      Upon any application or request by the Company to the Trustee to take any action under any provision of this Indenture, the Company shall furnish to the Trustee an Officers’
        Certificate stating that all conditions precedent, if any, provided for in this Indenture (including covenants, compliance with which constitute conditions precedent) relating to the proposed action have been complied with and an Opinion of Counsel
        stating that in the opinion of such counsel all such conditions precedent, if any, have been complied with, except that in the case of any such application or request as to which the furnishing of such documents is specifically required by any

      7

      

      
        
          


      

      Every certificate or opinion with respect to compliance with a condition or covenant provided for in this Indenture (excluding certificates delivered pursuant to Section 1009)
        shall include:

      (1) a statement that each individual signing such certificate or opinion has

      SECTION 103.    Form of Documents Delivered to
          Trustee. 

      In any case where several matters are required to be certified by, or covered by an opinion of, any specified Person, it is not necessary that all such matters be certified by,
        or covered by the opinion of, only one such Person, or that they be so certified or covered by only one document, but one such Person may certify or give an opinion as to some matters and one or more other such Persons as to other matters, and any
        such Person may certify or give an opinion as to such matters in one or several documents.

      Any certificate or opinion of an officer of the Company may be based, insofar as it relates to legal matters, upon an Opinion of Counsel, or a certificate or representations by
        counsel, unless such officer knows, or in the exercise of reasonable care should know, that the opinion, certificate or representations with respect to the matters upon which his certificate or opinion is based are erroneous. Any such Opinion of
        Counsel or certificate or representations may be based, insofar as it relates to factual matters, upon a certificate or opinion of, or representations by, an officer or officers of the Company stating that the information as to such factual matters
        is in the possession of the Company, unless such counsel knows that the certificate or opinion or representations as to such matters are erroneous.

      Where any Person is required to make, give or execute two or more applications, requests, consents, certificates, statements, opinions or other instruments under this
        Indenture, they may, but need not, be consolidated and form one instrument.

      SECTION 104.    Acts of Holders. 

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

       8

        

      
        
          


      

      made in the manner provided in this Section. The record of any meeting of Holders of Securities shall be proved in the manner provided in Section 1406. 

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

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

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

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

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

      SECTION 105.    Notices, etc. 

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

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

      9

      

      
        
          


      

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

      SECTION 106.    Notice to Holders; Waiver. 

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

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

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

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

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

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

      SECTION 107.    Effect of Headings and Table of
          Contents. 

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

        SECTION 108.    Successors and Assigns.

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

      SECTION 109.    Separability Clause. 

      In case any provision in this Indenture or in any Security or coupon shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining
        provisions shall not in any way be affected or impaired thereby.

      SECTION 110.    Benefits of Indenture. 

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

      SECTION 111.    No Personal Liability. 

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

      SECTION 112.    Governing Law. 

      This Indenture and the Securities and coupons shall be governed by and construed in accordance with the laws of the State of New York and for all purposes shall be governed by and construed in accordance with the law of said State, excluding its conflict of laws rules to the extent such rules would apply the law of another jurisdiction. This
        Indenture is subject to the provisions of the TIA that are required to be part of this Indenture and shall, to the extent applicable, be governed by such provisions.

      SECTION 113.    Legal Holidays. 

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

      SECTION 114.    Counterparts Originals; Electronic Signatures.

      This Indenture may be executed in any number of counterparts, each of which so executed shall be deemed to be an original, but all such counterparts shall together constitute
        but one and the same instrument. The exchange of copies of this Indenture and of signature pages by facsimile or PDF transmission shall constitute effective execution and delivery of this Indenture as to the parties hereto and may be used in lieu
        of the original Indenture for all purposes. Signatures of the parties hereto transmitted by facsimile or PDF shall be deemed to be their original signatures for all purposes. The words “execution,” “signed,” “signature,” and words of similar import
        in this Indenture and the Notes shall be deemed to include electronic or digital signatures or the keeping of records in electronic form, each of which shall be of the same effect, validity, and enforceability as manually executed signatures or a
        paper-based recordkeeping system, as the case may be, to the extent and as provided for under applicable law, including the Electronic Signatures in Global and National Commerce Act of 2000 (15 U.S.C. §§ 7001-7006), the Electronic Signatures and
        Records Act of 1999 (N.Y. State Tech. §§ 301-309), or any other similar state laws based on the Uniform Electronic Transactions Act; provided that, notwithstanding anything herein to the contrary, the Trustee is not under any obligation to agree to
        accept electronic signatures in any form or in any format unless expressly agreed to by such Trustee pursuant to procedures approved by such Trustee.

        SECURITIES FORMS

      

      

      SECTION 201.    Forms of Securities. 

      The Registered Securities, if any, of each series and the Bearer Securities, if any, and related coupons of each series, shall be in substantially the forms as shall be
        established in or pursuant to one or more indentures supplemental hereto or Board Resolutions, shall have such appropriate insertions, omissions, substitutions and other variations as are required or permitted by this Indenture or any indenture
        supplemental hereto, and may have such letters, numbers or other marks of identification or designation and such legends or endorsements placed thereon as the Company may deem appropriate and as are not inconsistent with the provisions of this
        Indenture, or as may be required to comply with any law or with any rule or regulation made pursuant thereto or with any rule or regulation of any stock exchange on which the Securities may be listed, or to conform to usage.

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

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

      SECTION 202.    Form of Trustee’s Certificate of
          Authentication. 

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

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

      ________________, as Trustee

      By

      Authorized Officer

      

      

      SECTION 203.    Securities Issuable in Global Form. 

      12

        

      
        
          


      

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

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

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

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

      Notwithstanding any other provision of this Indenture, so long as a series of Securities is a Global Security, the parties hereto will be bound at all times by the procedures
        of the applicable depositary with respect to such series.

        to unissued Securities of or within the series when issued from time to time):

      (1) the title of the Securities of or within the series (that shall distinguish
        the Securities of such series from all other series of Securities); 

      (2) any limit upon the aggregate principal amount of the Securities of or
        within the series that may be authenticated and delivered under this Indenture (except for Securities authenticated and delivered upon registration

      of transfer of, or in exchange for, or in lieu of, other Securities of or within the series pursuant to Section 304, 305, 306, 906 or 1107); 

      (3) the date or dates, or the method by which such date or dates will be
        determined, on which the principal of the Securities of or within the series shall be payable and the amount of principal payable thereon; 

      (4) the rate or rates (that may be fixed or variable) at which the Securities

      (19) the applicability, if any, of Sections 1302 and/or 1303 to the Securities
        of or within the series and any provisions in modification of, in addition to or in lieu of any of the provisions of Article Thirteen; 

      (20) if the Securities of such series are to be issuable in definitive form

        and, if so, whether the Company will have the option to redeem such Securities rather than pay such Additional Amounts (and the terms of any such option); 

      (22) the obligation, if any, of the Company to permit the Securities of such
        series to be converted into or exchanged for common stock of the Company or other securities or property of the Company and the terms and

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

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

      (24) any other terms of the series (which terms shall not be
        inconsistent with the provisions of this Indenture except as permitted by Section 905). 

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

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

      SECTION 302.    Denominations. 

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

      SECTION 303.    Execution, Authentication, Delivery
          and Dating. 

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

      Securities or coupons appertaining thereto bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Company shall bind the
        Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at the date of such Securities or coupons.

      At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities of any series, together with any coupon appertaining
        thereto, executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Securities, and the Trustee in accordance with the Company Order shall authenticate and deliver such
        Securities; provided, however, that, in connection with its original issuance, no Bearer Security shall be mailed or otherwise delivered to any location in the United States; and provided further that, unless otherwise specified with respect to any
        series of Securities pursuant to Section 301 a Bearer Security may be delivered in connection with its original issuance only if the Person entitled to receive such Bearer Security shall have furnished a certificate to Euroclear or Clearstream, as
        the case may be, in the form set forth in Exhibit A-1 to this Indenture or such other certificate as may be specified with respect to any series of Securities pursuant to Section 301, dated no earlier than 15 days prior to the earlier of the date
        on which such Bearer Security is delivered and the date on which any temporary Security first becomes exchangeable for such Bearer Security in accordance with the terms of such temporary Security and this Indenture.

      16

      

      
        
          


      

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

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

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

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

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

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

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

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

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

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

       17

      

      
        
          


      

      the Company, for all purposes of this Indenture such Security shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits of this
        Indenture.

      SECTION 304.    Temporary Securities. 

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

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

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

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

      18

      

      
        
          


      

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

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

      SECTION 305.    Registration, Registration of
          Transfer and Exchange. 

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

      19

      

      
        
          


      

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

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

      Notwithstanding the foregoing, except as otherwise specified as contemplated by Section 301, any permanent global Security shall be exchangeable only as provided in this
        paragraph. If the depository for any permanent global Security is DTC, then, unless the terms of such global Security expressly permit such global Security to be exchanged in whole or in part for definitive Securities, a global Security may be
        transferred, in whole but not in part, only to a nominee of DTC, or by a nominee of DTC to DTC, or to a successor to DTC for such global Security selected or approved by the Company or to a nominee of such successor to DTC. If at any time DTC
        notifies the Company that it is unwilling or unable to continue as depository for the applicable global Security or Securities or if at any time DTC ceases to be a clearing agency registered under the Exchange Act if so required by applicable law
        or regulation, the Company shall appoint a successor depository with respect to such global Security or Securities. If (x) a successor depository for such global Security or Securities is not appointed by the Company within 90 days after the
        Company receives such notice or becomes aware of such unwillingness, inability or ineligibility, (y) an Event of Default has occurred and is continuing and the beneficial owners representing a majority in principal amount of the applicable series
        of Securities represented by such global Security or Securities advise DTC to cease acting as depository for such global Security or Securities or (z) the Company, in its sole discretion, determines at any time that all Outstanding Securities (but
        not less than all) of any series issued or issuable in the form of one or more global Securities shall no longer be represented by such global Security or Securities (provided, however, the Company may not make such determination during the 40-day
        restricted period provided by Regulation S under the Securities Act or during any other similar period during which the Securities must be held in global form as may be required by the Securities Act), then the Company shall execute, and the
        Trustee shall authenticate and deliver definitive Securities of like series, rank, tenor and terms in definitive form in an aggregate principal amount equal to the principal amount of such global Security or Securities. If any beneficial owner of
        an interest in a permanent global Security is otherwise entitled to exchange such an interest for Securities 

       20

      

      
        
          


      

      of such series and of like tenor and principal amount of another authorized form and denomination, as specified as contemplated by Section 301 and provided that any applicable notice provided in
        the permanent global Security shall have been given, then without unnecessary delay but in any event not later than the earliest date on which such interest may be so exchanged, the Company shall execute, and the Trustee shall authenticate and
        deliver definitive Securities in aggregate principal amount equal to the principal amount of such beneficial owner’s interest in such permanent global Security. On or after the earliest date on which such interests may be so exchanged, such
        permanent global Security shall be surrendered for exchange by DTC or such other depository as shall be specified in the Company Order with respect thereto to the Trustee, as the Company’s agent for such purpose; provided, however, that no such
        exchanges may occur during a period beginning at the opening of business 15 days before any selection of Securities to be redeemed and ending on the relevant Redemption Date if the Security for which exchange is requested may be among those
        selected for redemption; and provided further that no Bearer Security delivered in exchange for a portion of a permanent global Security shall be mailed or otherwise delivered to any location in the United States. If a Registered Security is issued
        in exchange for any portion of a permanent global Security after the close of business at the office or agency where such exchange occurs on (i) any Regular Record Date and before the opening of business at such office or agency on the relevant
        Interest Payment Date, or (ii) any Special Record Date and before the opening of business at such office or agency on the related proposed date for payment of Defaulted Interest, interest or Defaulted Interest, as the case may be, will not be
        payable on such Interest Payment Date or proposed date for payment, as the case may be, in respect of such Registered Security, but will be payable on such Interest Payment Date or proposed date for payment, as the case may be, only to the Person
        to whom interest in respect of such portion of such permanent global Security is payable in accordance with the provisions of this Indenture.

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

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

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

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

      SECTION 306.    Mutilated, Destroyed, Lost and
          Stolen Securities. 

      If any mutilated Security or a Security with a mutilated coupon appertaining to it is surrendered to the Trustee or the Company, together with such security or indemnity as may
        be required by the Company or the Trustee to save each of them or any agent of either of them harmless, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of the same series and principal
        amount, 

       21

      

      
        
          


      

      containing identical terms and provisions and bearing a number not contemporaneously outstanding, with coupons corresponding to the coupons, if any, appertaining to the surrendered Security.

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

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

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

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

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

      SECTION 307.    Payment of Interest; Interest Rights
          Preserved. 

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

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

      22

      

      
        
          


      

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

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

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

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

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

      23

      

      
        
          


      

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

      Subject to the provisions of Section 1302 and except as otherwise specified with respect to a series of Securities in accordance with the provisions of Section 301, in the case
        of any Security that is converted or exchanged after any Regular Record Date and on or prior to the next succeeding Interest Payment Date (other than any Security, the principal of (or premium, if any, on) which shall become due and payable,
        whether at a Stated Maturity or by declaration of acceleration, call for redemption, or otherwise, prior to such Interest Payment Date), interest whose Stated Maturity is on such Interest Payment Date shall be payable on such Interest Payment Date
        notwithstanding such conversion or exchange, and such interest (whether or not punctually paid or duly provided for) shall be paid to the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of
        business on such Regular Record Date. Except as otherwise expressly provided in the immediately preceding sentence, in the case of any Security which is converted or exchanged, interest whose Stated Maturity is after the date of conversion or
        exchange of such Security shall not be payable.

       SECTION 308.    Persons Deemed Owners. 

       

        

      Prior to due presentment of a Registered Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in
        whose name such Registered Security is registered as the owner of such Security for the purpose of receiving payment of principal of (and premium or Make-Whole  Amount, if any), and (subject to Sections 305 and 307) interest on, such Registered
        Security and for all other purposes whatsoever, whether or not such Registered Security be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary.

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

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

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

      SECTION 309.    Cancellation. 

      All Securities and coupons surrendered for payment, redemption, repayment, registration of transfer or exchange or for credit against any sinking fund payment shall, if
        surrendered to any Person other than the Trustee, be delivered to the Trustee, and any such Securities and coupons and Securities and coupons surrendered directly to the Trustee for any such purpose shall be promptly canceled by it. The Company may
        at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder that 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 that the Company has not issued and sold, and all Securities so delivered shall be promptly canceled by the Trustee. If the Company shall so acquire any of the
        Securities, however, such acquisition shall not operate as a redemption or satisfaction of the indebtedness represented by such Securities unless and until the same are surrendered to the Trustee for cancellation. No Securities shall be
        authenticated in lieu of or in exchange for any Securities canceled as provided in this Section, 

       24

      

      
        
          


      

      except as expressly permitted by this Indenture. Cancelled Securities and coupons held by the Trustee shall be destroyed by the Trustee and, if required in writing by the Company, the Trustee
        shall deliver a certificate of such destruction to the Company, unless by a Company Order the Company directs their return to it.

      SECTION 310.    Computation of Interest. 

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

      ARTICLE FOUR

        

        SATISFACTION AND DISCHARGE

      

      

      SECTION 401.    Satisfaction and Discharge of
          Indenture. 

      This Indenture shall upon Company Request cease to be of further effect with respect to any series of Securities specified in such Company Request (except as to any surviving
        rights of registration of transfer or exchange of Securities of such series herein expressly provided for and any right to receive Additional Amounts, as provided in Section 1010), and the Trustee, upon receipt of a Company Order, and at the
        expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture as to such series when

      (1)            either 

        (A) all Securities of such series theretofore authenticated and delivered and
        all coupons, if any, appertaining thereto (other than (i) coupons appertaining to Bearer Securities surrendered for exchange for Registered Securities and maturing after such exchange, whose surrender is not required or has been waived as provided
        in Section 305, (ii) Securities and coupons of such series that have been destroyed, lost or stolen and that have been replaced or paid as provided in Section 306, (iii) coupons appertaining to Securities called for redemption and maturing after
        the relevant Redemption Date, whose surrender has been waived as provided in Section 1106, and (iv) Securities and coupons of such series 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 1003) have been delivered to the Trustee for cancellation; or 

        (B) all Securities of such series and, in the case of (i) or (ii) below, any
        coupons appertaining thereto not theretofore delivered to the Trustee for cancellation 

      (i)             have become due and payable, or 

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

      (iii)           if redeemable at the option of the Company, are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of
        notice of redemption by the Trustee in the name, and at the expense, of the Company, and the Company, in the case of (i), (ii) or (iii) above, has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust for the
        purpose an amount in the currency or currencies, currency unit or units or composite currency or currencies in which the Securities of such series are payable, sufficient to pay and discharge the entire indebtedness on such Securities and such
        coupons not theretofore delivered to the Trustee for cancellation, for principal (and premium or Make-Whole Amount, if any) and interest, and any Additional Amounts with respect thereto, to the date of such deposit (in the case of Securities that
        have become due and payable) or the Stated Maturity or Redemption Date, as the case may be;

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

      25

      

      
        
          


      

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

      Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee and any predecessor Trustee under Section 606, the obligations
        of the Company to any Authenticating Agent under Section 611 and, if money shall have been deposited with and held by the Trustee pursuant to subclause (B) of clause (1) of this Section, the obligations of the Trustee under Section 402 and the last
        paragraph of Section 1003, shall survive.

      In the event that there are Securities of two or more series outstanding hereunder, the Trustee shall be required to execute an instrument acknowledging satisfaction and
        discharge of this Indenture only if requested to do so with respect to Securities of a particular series as to which it is Trustee and if the other conditions thereto are met.

      SECTION 402.    Application of Trust Funds. 

      Subject to the provisions of the last paragraph of Section 1003, all money deposited with the Trustee pursuant to Section 401 shall be held in trust and applied by it, in
        accordance with the provisions of the Securities, the coupons 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 premium or Make-Whole Amount, if any), and any interest and Additional Amounts for whose payment such money has been deposited with or received by the Trustee, but such money need not be segregated from other
        funds except to the extent required by law.

      ARTICLE FIVE

          

          REMEDIES

      SECTION 501.    Events of Default. 

      Subject to any modifications, additions or deletions relating to any series of Securities as contemplated pursuant to Section 301, “Event of Default,” wherever used herein with
        respect to any particular series of Securities, means any one of the following events (whatever the reason for such Event of Default and whether or not 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) default in the payment of any interest upon or any Additional Amounts
        payable in respect of any Security of or within that series or of any coupon appertaining thereto, when such interest, Additional Amounts or coupon becomes due and payable, and continuance of such default for a period of 30 days; or

        terms of any Security of that series; or 

      (4) default in the performance, or breach, of any covenant or warranty of the

        default in whose performance or whose breach is elsewhere in this Section specifically dealt with), and continuance of such default or breach for a period of 90 days after there has been given, by registered or certified mail, 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 such default or breach and requiring it to be remedied and stating that such
        notice is a “Notice of Default” hereunder; or 

      (5) the Company pursuant to or within the meaning of any Bankruptcy Law:

        decree remains unstayed and in effect for 90 days; or 

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

      As used in this Section 501, the term “Bankruptcy Law” means Title 11, U.S. Code or any similar Federal or state law for the relief of debtors and the term “Custodian” means
        any receiver, trustee, assignee, liquidator or other similar official under any Bankruptcy Law.

      SECTION 502.    Acceleration of Maturity; Rescission
          and Annulment. 

      If an Event of Default with respect to Securities of any series at the time Outstanding occurs and is continuing, then and in every such case the Trustee or the Holders of not
        less than 25% in aggregate principal amount of the Outstanding Securities of each such affected series (voting as a single class) may declare the principal (or, if any Securities are Original Issue Discount Securities or Indexed Securities, such
        portion of the principal as may be specified in the terms thereof) of, and the Make-Whole Amount, if any, on, all 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
        the Holders), and upon any such declaration such principal or specified portion thereof shall become immediately due and payable.

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

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

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

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

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

      27

      

      
        
          


      

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

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

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

      SECTION 503.    Collection of Indebtedness and Suits
          for Enforcement by Trustee. 

      The Company covenants that if:

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

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

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

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

      SECTION 504.    Trustee May File Proofs of Claim. 

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

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

       28

        

      
        
          


      

      compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders allowed in such judicial proceeding, and 

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

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

      Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder of a Security or coupon any plan of
        reorganization, arrangement, adjustment or composition affecting the Securities or coupons or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder of a Security or coupon in any such
        proceeding.

      SECTION 505.    Trustee May Enforce Claims Without
          Possession of Securities or Coupons. 

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

      SECTION 506.    Application of Money Collected. 

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

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

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

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

      SECTION 507.    Limitation on Suits. 

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

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

       

      

       29

      

      
        
          


      

      (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 the Trustee 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 such Holders. 

      SECTION 508.    Unconditional Right of Holders to
          Receive Principal, Premium or Make-Whole Amount, if any, Interest and Additional Amounts. 

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

      SECTION 509.    Restoration of Rights and Remedies. 

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

      SECTION 510.    Rights and Remedies Cumulative. 

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

      SECTION 511.    Delay or Omission Not Waiver. 

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

      SECTION 512.    Control by Holders of Securities. 

      30

        

      
        
          


      

      The Holders of not less than 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 that is
        not inconsistent with such direction, and 

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

      SECTION 513.    Waiver of Past Defaults. 

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

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

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

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

      SECTION 514.    Waiver of Stay 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 stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives
        all benefit or advantage of any such law, and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been
        enacted.

      SECTION 515.    Undertaking for Costs. 

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

      ARTICLE SIX

        

        THE TRUSTEE

      

      

      SECTION 601.    Notice of Defaults. 

      Within 90 days after the occurrence of any default hereunder with respect to the Securities of any series, the Trustee shall transmit in the manner and to the extent provided
        in TIA Section 313(c), notice of such default hereunder actually known to a Responsible Officer of the Trustee, unless such default shall have been cured or waived; provided, however, that, except in the case of a default in the payment of the
        principal of (or premium or Make-Whole Amount, if any) or interest on or any Additional Amounts with respect to any Security of such series, or in the payment of any sinking fund installment with respect to the Securities of such series, the
        Trustee shall be protected in withholding such notice if and so long as Responsible Officers of the Trustee in good faith determine that the withholding of such notice is in the interests of the Holders of the Securities and coupons of such series;
        and provided further that in the case of any default or breach of the character specified in Section 501(4) with respect to the Securities and coupons of such series, no such notice to Holders shall be given until at least 60 days after the
        occurrence thereof. For the purpose of this Section, the term “default” means any event that is, or after notice or lapse of time or both would become, an Event of Default with respect to the Securities of such series.

      SECTION 602.    Certain Rights of Trustee. 

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

      (1) the Trustee shall perform only such duties as are expressly undertaken by
        it to perform under this Indenture and no implied covenants or obligations shall be read into this Indenture against the Trustee; 

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

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

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

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

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

      (7) the Trustee shall not be bound to make any investigation into the facts or
        matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, 

       32

        

      
        
          


      

      debenture, note, coupon or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the
        Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney; 

      (8) the Trustee may execute any of the trusts or powers hereunder or perform
        any duties hereunder either directly or by or through agents, attorneys, custodians or nominees and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent, attorney, custodian or nominee appointed with due
        care by it hereunder; 

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

      (10)             in no event shall the Trustee be responsible or liable for special, indirect, 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; 

      (11)             the Trustee shall not be deemed to have notice of any Default or Event of Default unless a Responsible Officer of the Trustee has actual knowledge thereof or
        unless written notice of any event which is in fact such a default is received by the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Securities and this Indenture; 

      (12)             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 to each agent, custodian and other Person employed to act hereunder; and 

      (13)             the Trustee may request that the Company deliver a certificate setting forth the names of individuals and/or titles of officers authorized at such time to take
        specified actions pursuant to this Indenture. 

      SECTION 603.    Not Responsible for Recitals or
          Issuance of Securities. 

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

      SECTION 604.    May Hold Securities. 

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

      SECTION 605.    Money Held in Trust. 

       

      

      33

        

      
        
          


      

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

      SECTION 606.    Compensation and Reimbursement. 

      The Company agrees:

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

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

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

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

      When the Trustee incurs expenses or renders services in connection with an Event of Default described in Section 501(5) and (6), such expenses (including the fees and expenses
        of its counsel) and the compensation for such services are intended to constitute expenses of administration under any Bankruptcy Law.

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

      SECTION 607.    Corporate Trustee Required;
          Eligibility. 

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

      SECTION 608.    Resignation and Removal; Appointment
          of Successor. 

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

       

      

      34

      

      
        
          


      

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

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

      (d) If at any time: 

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

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

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

      (e) If the Trustee shall resign, be removed or become incapable of acting, or
        if a vacancy shall occur in the office of Trustee for any cause with respect to the Securities of one or more series, the Company, by or  pursuant to a Board Resolution, shall promptly appoint a successor Trustee or Trustees with respect to the
        Securities of that or those series (it being understood that any such successor Trustee may be appointed with respect to the Securities of one or more or all of such series and that at any time there shall be only one Trustee with respect to the
        Securities of any particular series). If, within one year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee with respect to the Securities of any series shall be appointed by Act of the Holders
        of a majority in principal amount of the Outstanding Securities of such series delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment, become the successor
        Trustee with respect to the Securities of such series and to that extent supersede the successor Trustee appointed by the Company. If no successor Trustee with respect to the Securities of any series shall have been so appointed by the Company or
        the Holders of Securities and accepted appointment in the manner hereinafter provided, any Holder of a Security who has been a bona fide Holder of a Security of such series for at least six months may, on behalf of himself and all others similarly
        situated, petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to Securities of such series.

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

      SECTION 609.    Acceptance of Appointment By
          Successor. 

      (a) In case of the appointment hereunder of a successor Trustee with respect to
        all Securities, every such successor Trustee shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become
        effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with 

       35

        

      
        
          


      

      all the rights, powers, trusts and duties of the retiring Trustee; but, on request of the Company or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and
        deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee, and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee
        hereunder, subject nevertheless to its claim, if any, provided for in Section 606. 

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

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

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

      (e) All monies due and owing to the Trustee shall be paid before the Successor
        Trustee takes over. 

      SECTION 610.    Merger, Conversion, Consolidation or
          Succession to Business. 

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

      SECTION 611.    Appointment of Authenticating
          Agent. 

      At any time when any of the Securities remain Outstanding, the Trustee may appoint an Authenticating Agent or Agents with respect to one or more series of Securities that shall
        be authorized to act on behalf of the 

       36

      

      
        
          


      

      Trustee to authenticate Securities of such series issued upon exchange, registration of transfer or partial redemption or repayment thereof or pursuant to Section 306, and Securities so
        authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Any such appointment shall be evidenced by an instrument in writing signed by a
        Responsible Officer of the Trustee, a copy of which instrument shall be promptly furnished to the Company. Wherever reference is made in this Indenture to the authentication and delivery of Securities by the Trustee or the Trustee’s certificate of
        authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent. Each
        Authenticating Agent shall be reasonably acceptable to the Company and, except as may otherwise be provided pursuant to Section 301, shall at all times be a bank or trust company or corporation organized and doing business and in good standing
        under the laws of the United States of America or of any State or the District of Columbia, authorized under such laws to act as Authenticating Agent, having a combined capital and surplus of not less than $25,000,000 and subject to supervision or
        examination by Federal or State authorities. If such Authenticating Agent publishes reports of condition at least annually, pursuant to law or the requirements of the aforesaid supervising or examining authority, then for the purposes of this
        Section, the combined capital and surplus of such Authenticating Agent shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. In case at any time an Authenticating Agent shall cease
        to be eligible in accordance with the provisions of this Section, such Authenticating Agent shall resign immediately in the manner and with the effect specified in this Section.

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

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

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

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

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

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

      SECTION 613.    Conflicting Interests. 

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

        Authenticating Agent nor any Paying Agent nor any Security Registrar nor any director, officer, agent or employee of any of them shall be held accountable by reason of the disclosure of any information as to the names and addresses of the Holders
        of Securities or coupons in accordance with TIA Section 312, regardless of the source from which such information was derived, and that the Trustee shall not be held accountable by reason of mailing any material pursuant to a request made under TIA
        Section 312(b).

      SECTION 702.    Reports by Trustee. 

      Within 60 days after June 15 of each year commencing with the first June 15 after the first issuance of Securities pursuant to this Indenture, the Trustee shall transmit by

        Company may be required to file with the Commission pursuant to Section 13 or Section 15(d) of the Exchange Act; or, if the Company is not required to file information, documents or reports pursuant to either of such Sections, then it will file
        with the Trustee and the Commission, in accordance with rules and regulations prescribed from time to time by the Commission, such of the supplementary and periodic information, documents and reports that may be required pursuant to Section 13 of
        the Exchange Act in respect of a security listed and registered on a national securities exchange as may be prescribed from time to time in such rules and regulations; 

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

      38

      

      
        
          


      

      (3) transmit by mail (or to the extent permitted by applicable
        procedures or regulations, deliver electronically) to the Holders of Securities, within 30 days after the filing thereof with the Trustee, in the manner and to the extent provided in TIA Section 313(c), such summaries of any information, documents
        and reports required to be filed by the Company pursuant to paragraphs (1) or (2) of this Section as may be required by rules and regulations prescribed from time to time by the Commission.

        Date for interest for such series of Securities, semi-annually, upon such dates as are set forth in the Board Resolution or indenture supplemental hereto authorizing such series, and 

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

        CONSOLIDATION, MERGER, SALE, LEASE OR CONVEYANCE

      

      

      SECTION 801.    Consolidations and Mergers of
          Company and Sales, Leases and Conveyances Permitted Subject to Certain Conditions. 

      The Company may consolidate with, or sell, lease or convey all or substantially all of its assets to, or merge with or into any other Person, provided that in any such case,
        (i) either the Company shall be the continuing entity, or the successor (if other than the Company) entity shall be a Person organized and existing under the laws of the United States or a State thereof or the District of Columbia and such
        successor entity shall expressly assume the due and punctual payment of the principal of (and premium or Make-Whole Amount, if any) and any interest (including all Additional Amounts, if any, payable pursuant to Section 1010) on all of the
        Securities, according to their tenor, or as otherwise specified pursuant to Section 301, and the due and punctual performance and observance of all of the covenants and conditions of this Indenture to be performed by the Company by supplemental
        indenture, complying with Article Nine hereof, satisfactory to the Trustee, executed and delivered to the Trustee by such Person and (ii) immediately after giving effect to such transaction, no Event of Default, and no event that, after notice or
        the lapse of time, or both, would become an Event of Default, shall have occurred and be continuing.

          Corporation. 

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

      39

      

      
        
          


      

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

          Counsel. 

      Any consolidation, merger, sale, lease or conveyance permitted under Section 801 is also subject to the condition that the Trustee receive an Officers’ Certificate and an
        Opinion of Counsel to the effect that any such consolidation, merger, sale, lease or conveyance, and the assumption by any successor entity, complies with the provisions of this Article and that all conditions precedent herein provided for relating

      SECTION 901.    Supplemental Indentures without
          Consent of Holders. 

      Without the consent of any Holders of Securities or coupons, the Company, when authorized by or pursuant to a Board Resolution, and the Trustee, 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:

      (1) to evidence the succession of another Person to the Company and the
        assumption by any such successor of the covenants of the Company herein and in the Securities contained; or 

      (2) to add to the covenants of the Company for the benefit of the Holders of
        all or any series of Securities (and, if such covenants are to be for the benefit of less than all series of Securities, stating that such covenants are expressly being included solely for the benefit of such series) or to surrender any right or
        power herein conferred upon the Company; or 

      (3) to add any additional Events of Default for the benefit of the Holders of
        all or any series of Securities (and if such Events of Default are to be for the benefit of less than all series of Securities, stating that such  Events of Default are expressly being included solely for the benefit of such series); provided,
        however, that in respect of any such additional Events of Default such supplemental indenture may provide for a particular period of grace after default (which period may be shorter or longer than that allowed in the case of other defaults) or may
        provide for an immediate enforcement upon such default or may limit the remedies available to the Trustee upon such default or may limit the right of the Holders of a majority in aggregate principal amount of that or those series of Securities to
        which such additional Events of Default apply to waive such default; or

      (4) to add to or change any of the provisions of this Indenture to provide that
        Bearer Securities may be registrable as to principal, to change or eliminate any restrictions on the payment of principal of or any premium, Make-Whole Amount or Interest on Bearer Securities, to permit Bearer Securities to be issued in exchange
        for Registered Securities, to permit Bearer Securities to be issued in exchange for Bearer Securities of other authorized denominations or to permit or facilitate the issuance of Securities in uncertificated form, provided that any such action
        shall not adversely affect the interests of the Holders of Securities of any series or any related coupons in any material respect; or 

      (5) to add to, change or eliminate any of the provisions of this Indenture in
        respect of any series of Securities, provided that any such addition, change or elimination shall (i) neither (A) apply to any Security of any series created prior to the execution of such supplemental indenture and entitled to the benefit of such
        provision, nor (B) modify the rights of the Holder of any such Security with respect to such provision; or (ii) become effective only when there is no Security Outstanding; or 

      (6) to secure the Securities; or 

      40

      

      
        
          


      

      (7) to establish the form or terms of Securities of any series and any related
        coupons as permitted by Sections 201 and 301, including the provisions and procedures relating to Securities convertible into or exchangeable for other securities or property of the Company; or 

      (8) to evidence and provide for the acceptance of appointment hereunder by a
        successor Trustee with respect to the Securities of one or more series and to add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one
        Trustee; or 

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

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

      (11) to supplement any of the provisions of this Indenture to such extent as
        shall be necessary to permit or facilitate the defeasance and discharge of any series of Securities pursuant to Sections 401, 1302 and 1303; provided in each case that any such action shall not adversely affect the interests of the Holders of
        Securities of such series and any related coupons or any other series of Securities in any material respect. 

      SECTION 902.    Supplemental Indentures with Consent
          of Holders. 

      The Company and the Trustee may (i) amend or supplement this Indenture or the Securities without notice to any Holder of Securities but with the written consent of the Holders
        of a majority in aggregate principal amount of the Securities of all series then outstanding or (ii) supplement this Indenture with regard to a series of Securities, amend or supplement a Supplemental Indenture relating to a series of Securities,
        or amend the Securities of a series, without notice to any Holder of Securities but with the written consent of the Holders of a majority in aggregate principal amount of the Securities of that series then outstanding. The Holders of a majority in
        principal amount of the Securities of all series then outstanding may waive compliance by the Company with any provision of this Indenture or the Securities without notice to any Holder of Securities. The Holders of a majority in principal amount 
        of the Securities of any series then outstanding may waive compliance with any provision of this Indenture, any Supplemental Indenture or the Securities of that series with regard to the Securities of that series without notice to any Holder of
        Securities. However, without the consent of the Holder of each Outstanding Security affected thereby, no amendment, supplement or waiver may:

      (1) change the Stated Maturity of the principal of (or premium or Make-Whole
        Amount, if any, on) or any installment of principal of or interest on, any Security; or reduce the principal amount thereof or the rate or amount of interest thereon or any Additional Amounts payable in respect thereof, or any premium or Make-Whole
        Amount payable upon the redemption thereof, or change any obligation of the Company to pay Additional Amounts pursuant to Section 1010 (except as contemplated by Section 801(i) and permitted by Section 901(1)), or reduce the amount of the principal
        of an Original Issue Discount Security or Make-Whole Amount, if any, that would be due and payable upon a declaration of acceleration of the Maturity thereof pursuant to Section 502 or the amount thereof provable in bankruptcy pursuant to
        Section 504, or change any Place of Payment where, or the currency or currencies, currency unit or units or composite currency or currencies in which, the principal of any Security or any premium or Make-Whole Amount or any Additional Amounts
        payable in respect thereof or the interest thereon is payable, or impair the right to institute suit for the enforcement of any such payment on or after the Stated Maturity thereof (or, in the case of redemption or repayment at the option of the
        Holder, on or after the Redemption Date or the Repayment Date, as the case may be); or 

      (2) reduce the percentage in principal amount of the Outstanding Securities of
        any series, the consent of whose Holders is required for any such supplemental indenture, or the consent of whose Holders is required for any waiver with respect to such series (or compliance with certain provisions of this Indenture or certain
        defaults hereunder and their consequences) provided for in this Indenture, or reduce the requirements of Section 1404 for quorum or voting; or 

      41

      

      
        
          


      

      (3) modify any of the provisions of this Section, Section 513 or Section 1011,
        except to increase the required percentage to effect such action or to provide that certain other provisions of this Indenture cannot be modified or waived without the consent of the Holder of each Outstanding Security affected thereby; or 

      (4) make any change that adversely affects the right to convert or exchange any
        Security pursuant to Section 301 or decrease the conversion or exchange rate or increase the conversion or exchange price of any such Security. 

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

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

      SECTION 903.    Execution of Supplemental
          Indentures. 

      In executing, or accepting the additional trusts created by, any supplemental indenture permitted by this Article or the modification thereby of the trusts created by this
        Indenture, the Trustee shall be entitled to receive, and shall be fully protected in relying upon, an Opinion of Counsel and an Officers’ Certificate stating that the execution of such supplemental indenture is authorized or permitted by this
        Indenture and that all conditions precedent to the execution of such supplemental indenture have been complied with. The Trustee may, but shall not be obligated to, enter into any such supplemental indenture that affects the Trustee’s own rights,
        duties or immunities under this Indenture or otherwise.

      SECTION 904.    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 and of any coupon appertaining thereto shall be bound thereby.

      SECTION 905.    Conformity with Trust Indenture
          Act. 

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

      SECTION 906.    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 authenticated and delivered by the Trustee in exchange for Outstanding Securities of such series.

      SECTION 907.    Notice of Supplemental Indentures. 

      Promptly after the execution by the Company and the Trustee of any supplemental indenture pursuant to the provisions of Section 902, the Company shall give notice thereof to
        the Holders of each Outstanding Security affected, in the manner provided for in Section 106, setting forth in general terms the substance of such supplemental indenture.

      ARTICLE TEN

        

        COVENANTS

      

      

      SECTION 1001.    Payment of Principal, Premium or
          Make-Whole Amount, if any, Interest and Additional Amounts. 

      The Company covenants and agrees for the benefit of the Holders of each series of Securities that it will duly and punctually pay the principal of (and premium or Make-Whole
        Amount, if any) and interest on and any Additional Amounts payable in respect of the Securities of that series in accordance with the terms of such series of Securities, any coupons appertaining thereto and this Indenture. Unless otherwise
        specified as contemplated by Section 301 with respect to any series of Securities, any interest due on and any Additional Amounts payable in respect of Bearer Securities on or before Maturity, other than Additional Amounts, if any, payable as
        provided in Section 1010 in respect of principal of (or premium or Make-Whole Amount, if any, on) such a Security, shall be payable only upon presentation and surrender of the several coupons for such interest installments as are evidenced thereby
        as they severally mature. Unless otherwise specified with respect to Securities of any series pursuant to Section 301, at the option of the Company, all payments of principal may be paid by check to the registered Holder of the Registered Security
        or other person entitled thereto against surrender of such Security.

      SECTION 1002.    Maintenance of Office or Agency. 

      If Securities of a series are issuable only as Registered Securities, the Company shall maintain in each Place of Payment for any series of Securities an office or agency where
        Securities of that series may be presented or surrendered for payment or conversion, where Securities of that series may be surrendered for registration of transfer or exchange, and where notices and demands to or upon the Company in respect of the
        Securities of that series and this Indenture may be served. If Securities of a series are issuable as Bearer Securities, the Company will maintain: (A) in the City of Olympia, Washington, an office or agency where any Registered Securities of that
        series may be presented or surrendered for payment or conversion, where any Registered Securities of that series may be surrendered for exchange, where notices and demands to or upon the Company in respect of the Securities of that series and this
        Indenture may be served and where Bearer Securities of that series and related coupons may be presented or surrendered for payment or conversion in the circumstances described in the following paragraph (and not otherwise); (B) subject to any laws
        or regulations applicable thereto, in a Place of Payment for that series that is located outside the United States, an office or agency where Securities of that series and related coupons may be presented and surrendered for payment (including
        payment of any Additional Amounts payable on Securities of that series pursuant to Section 1010) or conversion; provided, however, that if the Securities of that series are listed on the Luxembourg Stock Exchange, The International Stock Exchange
        or any other stock exchange located outside the United States and such stock exchange shall so require, the Company will maintain a Paying Agent for the Securities of that series in Luxembourg, London, England or any other required city located
        outside the United States, as the case may be, so long as the Securities of that series are listed on such exchange; and (C) subject to any laws or regulations applicable thereto, in each Place of Payment for that series located outside the United
        States an office or agency where any Securities of that series may be surrendered for registration of transfer, where Securities of that series may be surrendered for exchange 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 each 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, except that Bearer Securities
        of that series and the related coupons may be presented and surrendered for payment (including payment of any Additional Amounts payable on Bearer Securities of that series pursuant to Section 1010) at the offices specified in the Security, in
        London, England, and the Company hereby appoints the same as its agent to receive such respective presentations, surrenders, notices and demands, and the Company hereby appoints the Trustee its agent to receive all such presentations, surrenders,
        notices and demands.

      Unless otherwise specified with respect to any Securities pursuant to Section 301, no payment of principal, premium, Make-Whole Amount or interest on or Additional Amounts in
        respect of Bearer Securities shall be made at any office or agency of the Company in the United States or by check mailed to any address in the United States or by transfer to an account maintained with a bank located in the United States;
        provided, however, that, if the 

       43

      

      
        
          


      

      Securities of a series are payable in Dollars, payment of principal of and any premium and interest on any Bearer Security (including any Additional Amounts or Make-Whole Amount payable on
        Securities of such series pursuant to Section 1010) shall be made at the office of the Company’s Paying Agent in the City of Olympia, Washington, if (but only if) payment in Dollars of the full amount of such principal, premium, interest,
        Additional Amounts or Make-Whole Amount, as the case may be, at all offices or agencies outside the United States maintained for the purpose by the Company in accordance with this Indenture, is illegal or effectively precluded by exchange controls
        or other similar restrictions.

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

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

      SECTION 1003.    Money for Securities Payments to Be
          Held in Trust. 

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

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

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

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

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

       

      

      44

        

      
        
          


      

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

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

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

      SECTION 1004.    Existence. 

      Subject to Article Eight, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect the existence, rights (charter and
        statutory) and franchises of the Company and its Subsidiaries; provided, however, that the Company shall not be required to preserve any right or franchise if the Board of Directors shall determine that the preservation thereof is no longer
        desirable in the conduct of the business of the Company and its Subsidiaries as a whole and that the loss thereof is not disadvantageous in any material respect to the Holders of Securities of any series.

      SECTION 1005.    Maintenance of Properties. 

      The Company will cause all of its material properties used or useful in the conduct of its business or the business of any Subsidiary to be maintained and kept in good
        condition, repair and working order and supplied with all necessary equipment and will cause to be made all necessary repairs, renewals, replacements, betterments and improvements thereof, all as in the judgment of the Company may be necessary so
        that the business carried on in connection therewith may be properly and advantageously conducted at all times; provided, however, that nothing in this Section shall prevent the Company or any Subsidiary from selling or otherwise disposing of its
        properties in the ordinary course of its business.

      SECTION 1006.    Insurance. 

      The Company will, and will cause each of its Subsidiaries to, keep all its insurable properties insured against loss or damage with commercially reasonable amounts and types of
        insurance provided by insurers of recognized responsibility.

      SECTION 1007.    Payment of Taxes and Other Claims. 

      The Company will pay or discharge or cause to be paid or discharged, before the same shall become delinquent, (1) all taxes, assessments and governmental charges levied or
        imposed upon it or any Subsidiary or upon the income, profits or property of the Company or any Subsidiary, and (2) all lawful claims for labor, materials and supplies that, if unpaid, might by law become a lien upon the property of the Company or
        any Subsidiary; provided, 

       45

      

      
        
          


      

      however, that the Company shall not be required to pay or discharge or cause to be paid or discharged any such tax, assessment, charge or claim whose amount, applicability or validity is being
        contested in good faith by appropriate proceedings.

      SECTION 1008.    Provision of Financial
          Information. 

      (a) The Company covenants and agrees to comply with its obligations pursuant to
        Section 703. 

      (b) The Company’s obligations under this Section 1008 and Section 703(1) and
        (2) shall be deemed satisfied, and no further filing with or delivery to the Trustee of copies of such information, documents or reports shall be required pursuant to such Sections, to the extent the Company has filed such information, documents or
        reports with the Commission via the Electronic Data Gathering and Retrieval (EDGAR) or any successor system. 

      SECTION 1009.    Statement as to Compliance. 

      The Company will deliver to the Trustee within 120 days after the end of each fiscal year, a brief certificate from the principal executive officer, principal financial officer
        or principal accounting officer as to his or her knowledge of the Company’s compliance with all conditions and covenants under this Indenture and, in the event of any noncompliance, specifying such noncompliance and the nature and status thereof.
        For purposes of this Section 1009, such compliance shall be determined without regard to any period of grace or requirement of notice under this Indenture.

      SECTION 1010.    Additional Amounts. 

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

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

       46

      

      
        
          


      

      incurred without gross negligence or bad faith on their part arising out of or in connection with actions taken or omitted by any of them in reliance on any Officers’ Certificate furnished
        pursuant to this Section or in reliance on the Company’s not furnishing such an Officers’ Certificate.

      SECTION 1011.    Waiver of Certain Covenants. 

      The Company may omit in any particular instance to comply with any term, provision or condition set forth in Sections 1004 to 1008, inclusive, and with any other term,
        provision or condition with respect to the Securities of any series specified in accordance with Section 301 (except any such term, provision or condition that could not be amended without the consent of all Holders of Securities of such series
        pursuant to Section 902), if before or after the time for such compliance the Holders of at least a majority in principal amount of all outstanding Securities of such series, by Act of such Holders, either waive such compliance in such instance or
        generally waive compliance with such covenant or condition, but no such waiver shall extend to or affect such covenant or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the
        Company and the duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect.

      ARTICLE ELEVEN

        

        REDEMPTION OF SECURITIES

      

      

      SECTION 1101.    Applicability of Article. 

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

      SECTION 1102.    Election to Redeem; Notice to
          Trustee. 

      The election of the Company to redeem any Securities shall be evidenced by or pursuant to a Board Resolution. In case of any redemption at the election of the Company of less
        than all of the Securities of any series, the Company shall, at least 45 days prior to the giving of the notice of redemption in Section 1104 (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee, in writing, of such
        Redemption Date, of the principal amount of Securities of such series to be redeemed and of the Redemption Price of such Securities and any accrued interest and Additional Amounts payable with respect thereto, if any, on the Redemption Date. In the
        case of any redemption of Securities prior to the expiration of any restriction on such redemption provided in the terms of such Securities or elsewhere in this Indenture, the Company shall furnish the Trustee with an Officers’ Certificate and
        Opinion of Counsel evidencing compliance with such restriction.

      SECTION 1103.    Selection by Trustee of Securities
          to Be Redeemed. 

      If less than all the Securities of any series issued with the same terms are to be redeemed, the particular Securities to be redeemed shall be selected not more than 60 days
        prior to the Redemption Date by the Trustee, from the Outstanding Securities of such series issued on such date with the same terms not previously called for redemption, by such method as the Trustee shall deem fair and appropriate, subject to the
        rules and procedures of DTC, and that 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.

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

      47

      

      
        
          


      

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

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

      SECTION 1104.    Notice of Redemption. 

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

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

      All notices of redemption shall state:

      (1) the Redemption Date; 

      (2) the Redemption Price, accrued interest to the Redemption Date payable as
        provided in Section 1106, if any, and Additional Amounts, if any; 

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

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

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

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

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

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

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

      48

      

      
        
          


      

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

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

      (12) such other information as the Trustee reasonably deems appropriate. 

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

      SECTION 1105.    Deposit of Redemption Price. 

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

      SECTION 1106.    Securities Payable on Redemption
          Date. 

      Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein
        specified in the currency or currencies, currency unit or units or composite currency or currencies in which the Securities of such series are payable (except as otherwise specified pursuant to Section 301 for the Securities of such series)
        (together with accrued interest and Additional Amounts payable with respect thereto, if any, on the Redemption Date), and from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued interest and
        Additional

      Amounts, if any) such Securities shall, if the same were interest-bearing, cease to bear interest and the coupons for such interest appertaining to any Bearer Securities so to be redeemed, except
        to the extent provided below, shall be void. Upon surrender of any such Security for redemption in accordance with said notice, together with all coupons, if any, appertaining thereto maturing after the Redemption Date, such Security shall be paid
        by the Company at the Redemption Price, together with accrued interest and Additional Amounts payable with respect thereto, if any, on the Redemption Date; provided, however, that installments of interest on Bearer Securities whose Stated Maturity
        is on or prior to the Redemption Date shall be payable only at an office or agency located outside the United States (except as otherwise provided in Section 1002) and, unless otherwise specified as contemplated by Section 301, only upon
        presentation and surrender of coupons for such interest; and provided further that except as otherwise provided with respect to Securities convertible or exchangeable into other securities or property (including securities of other issuers,
        provided that such securities are registered under Section 12 of the Exchange Act and such issuer is then eligible to use Form S-3 (or any successor form) for a primary offering of its securities) of the Company, installments of interest on
        Registered Securities whose Stated Maturity is on or prior to the Redemption Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the relevant Record Dates
        according to their terms and the provisions of Section 307.

      If any Bearer Security surrendered for redemption shall not be accompanied by all appurtenant coupons maturing after the Redemption Date, such Security may be paid after
        deducting from the Redemption Price an amount equal to the face amount of all such missing coupons, or the surrender of such missing coupon or coupons may be waived by the Company and the Trustee if there be furnished to them such security or
        indemnity as they may require to save each of them and any Paying Agent harmless. If thereafter the Holder of such Security shall surrender to the Trustee or any Paying Agent any such missing coupon in respect of which a deduction shall have been
        made from the Redemption Price, such Holder shall be entitled to receive the amount so deducted; provided, 

       49

      

      
        
          


      

      however, that interest represented by coupons shall be payable only at an office or agency located outside the United States (except as otherwise provided in Section 1002) and, unless otherwise
        specified as contemplated by Section 301, only upon presentation and surrender of those coupons. If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal, (and premium or Make-Whole Amount, if
        any) shall, until paid, bear interest from the Redemption Date at the rate borne by the Security.

      SECTION 1107.    Securities Redeemed in Part. 

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

      ARTICLE TWELVE

        

        SINKING FUNDS

      

      

      SECTION 1201.    Applicability of Article. 

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

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

      SECTION 1202.    Satisfaction of Sinking Fund
          Payments with Securities. 

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

      SECTION 1203.    Redemption of Securities for
          Sinking Fund. 

      Not less than 60 days prior to each sinking fund payment date for Securities of any series, the Company will deliver to the Trustee an Officers’ Certificate specifying the
        amount of the next ensuing mandatory sinking fund payment for that series pursuant to the terms of that series, the portion thereof, if any, which is to be satisfied by payment of cash in the currency or currencies, currency unit or units or
        composite currency or currencies in which the Securities of such series are payable (except as otherwise specified pursuant to Section 301 for the Securities of such series) and the portion thereof, if any, which is to be satisfied by delivering
        and crediting Securities of that series pursuant to Section 1202, and the amount of optional sinking fund payments, if any, to be added in cash to the next ensuing mandatory sinking fund payment, and will also deliver to the Trustee any Securities
        to be so delivered 

       50

      

      
        
          


      

      and credited. If such Officers’ Certificate shall specify an optional amount to be added in cash to the next ensuing mandatory sinking fund payment, the Company shall thereupon be obligated to
        pay the amount therein specified. Not less than 30 days before each such sinking fund payment date the Trustee shall select the Securities to be redeemed upon such sinking fund payment date in the manner specified in Section 1103 and cause notice
        of the redemption thereof to be given in the name of and at the expense of the Company in the manner provided in Section 1104. Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner
        stated in Section 1106 and 1107.

      ARTICLE THIRTEEN

        

        DEFEASANCE AND COVENANT DEFEASANCE

      

      

      SECTION 1301.    Applicability of Article; Company’s
          Option to Effect Defeasance or Covenant Defeasance. 

      If, pursuant to Section 301, provision is made for either or both of (a) defeasance of the Securities of or within a series under Section 1302 or (b) covenant defeasance of the
        Securities of or within a series under Section 1303 to be applicable to the Securities of any series, then the provisions of such Section or Sections, as the case may be, together with the other provisions of this Article (with such modifications
        thereto as may be specified pursuant to Section 301 with respect to any Securities), shall be applicable to such Securities and any coupons appertaining thereto, and the Company may at its option by Board Resolution at any time, with respect to
        such Securities and any coupons appertaining thereto, elect to defease such Outstanding Securities and any coupons appertaining thereto pursuant to Section 1302 (if applicable) or Section 1303 (if applicable) upon compliance with the conditions set
        forth below in this Article.

      SECTION 1302.    Defeasance and Discharge. 

      Upon the Company’s exercise of the above option applicable to this Section with respect to any Securities of or within a series, the Company shall be deemed to have been
        discharged from its obligations with respect to such Outstanding Securities and any coupons appertaining thereto on the date the conditions set forth in Section 1304 are satisfied (hereinafter, “defeasance”). For this purpose, such defeasance means
        that the Company shall be deemed to have paid and discharged the entire indebtedness represented by such Outstanding Securities and any coupons appertaining thereto, which shall thereafter be deemed to be “Outstanding” only for the purposes of
        Section 1305 and the other Sections of this Indenture referred to in clauses (A) and (B) below, and to have satisfied all of its other obligations under such Securities and any coupons appertaining thereto and this Indenture insofar as such
        Securities and any coupons appertaining thereto are concerned (and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following that shall survive until otherwise terminated or
        discharged hereunder: (A) the rights of Holders of such Outstanding Securities and any coupons appertaining thereto to receive, solely from the trust fund described in Section 1304 and as more fully set forth in such Section, payments in respect of
        the principal of (and premium or Make-Whole Amount, if any) and interest, if any, on such Securities and any coupons appertaining thereto when such payments are due, (B) the Company’s obligations with respect to such Securities under Sections 305,
        306, 1002 and 1003 and with respect to the payment of Additional Amounts, if any, on such Securities as contemplated by Section 1010, (C) the rights, powers, trusts, duties and immunities of the Trustee hereunder including but not limited to
        Section 606 hereof and (D) this Article. Subject to compliance with this Article Thirteen, the Company may exercise its option under this Section notwithstanding the prior exercise of its option under Section 1303 with respect to such Securities
        and any coupons appertaining thereto.

      SECTION 1303.    Covenant Defeasance. 

      Upon the Company’s exercise of the above option applicable to this Section with respect to any Securities of or within a series, the Company shall be released from its
        obligations under Sections 1004 to 1008, inclusive, and, if specified pursuant to Section 301, its obligations under any other covenant, with respect to such Outstanding Securities and any coupons appertaining thereto on and after the date the
        conditions set forth in Section 1304 are satisfied (hereinafter, “ covenant defeasance ”), and such Securities and any coupons appertaining thereto shall thereafter be deemed to be not “Outstanding” for the purposes of any direction, waiver,
        consent or declaration or Act 

       51

      

      
        
          


      

      of Holders (and the consequences of any thereof) in connection with Sections 1004 to 1008, inclusive, or such other covenant, but shall continue to be deemed “Outstanding” for all other purposes
        hereunder. For this purpose, such covenant defeasance means that, with respect to such Outstanding Securities and any coupons appertaining thereto, the Company may omit to comply with and shall have no liability in respect of any term, condition or
        limitation set forth in any such Section or such other covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such Section or such other covenant or by reason of reference in any such Section or such other
        covenant to any other provision herein or in any other document and such omission to comply shall not constitute a default or an Event of Default under Section 501(4) or 501(7) or otherwise, as the case may be, but, except as specified above, the
        remainder of this Indenture and such Securities and any coupons appertaining thereto shall be unaffected thereby.

      SECTION 1304.    Conditions to Defeasance or
          Covenant Defeasance. 

      The following shall be the conditions to application of Section 1302 or Section 1303 to any Outstanding Securities of or within a series and any coupons appertaining thereto:

      (a) The Company shall irrevocably have deposited or caused to be deposited with
        the Trustee as trust funds in trust for the purpose of making the following payments, specifically pledged as security for, and dedicated solely to, the benefit of the Holders of such Securities and any coupons appertaining thereto, (1) an amount
        in such currency, currencies or currency unit in which such Securities and any coupons appertaining thereto are then specified as payable at Stated Maturity, or (2) Government Obligations applicable to such Securities and coupons appertaining
        thereto (determined on the basis of the currency, currencies or currency unit in which such Securities and coupons appertaining thereto are then specified as payable at Stated Maturity) 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 of principal of (and premium or Make-Whole Amount, if any) and interest and Additional Amounts, if any, on such Securities and
        any coupons appertaining thereto, money in an amount, or (3) a combination thereof in an amount, sufficient, without consideration of any reinvestment of such principal and interest, in the opinion of a nationally recognized firm of independent
        public accountants expressed in a written certification thereof delivered to the Trustee, to pay and discharge, and that shall be applied by the Trustee to pay and discharge, (i) the principal of (and premium or Make-Whole Amount, if any) and
        interest, if any, on such Outstanding Securities and any coupons appertaining thereto on the Stated Maturity of such principal or installment of principal or interest and (ii) any mandatory sinking fund payments or analogous payments applicable to
        such Outstanding Securities and any coupons appertaining thereto on the day on which such payments are due and payable in accordance with the terms of this Indenture and of such Securities and any coupons appertaining thereto; provided, that the
        Trustee shall have been irrevocably instructed to apply such money or the proceeds of such  Government Obligations to said payments with respect to such Securities. Before such a deposit, the Company may give to the Trustee, in accordance with
        Section 1102 hereof, a notice of its election to redeem all or any portion of such Outstanding Securities at a future date in accordance with the terms of the Securities of such series and Article Eleven hereof, which notice shall be irrevocable.
        Such irrevocable redemption notice, if given, shall be given effect in applying the foregoing.

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

      (c) No Event of Default or event that with notice or lapse of time or both
        would become an Event of Default with respect to such Securities and any coupons appertaining thereto shall have occurred and be continuing on the date of such deposit or, insofar as Sections 501(5) and 501(6) are concerned, at any time during the
        period ending on the 91st day after the date of such deposit (it being understood that this condition shall not be deemed satisfied until the expiration of such period). 

      (d) In the case of an election under Section 1302, the Company shall have
        delivered to the Trustee an Opinion of Counsel stating that (i) the Company has received from, or there has been published by, the Internal Revenue Service a ruling, or (ii) since the date of execution of this Indenture, there has been a change in
        the applicable Federal income tax law, in either case to the effect that, and based thereon such opinion shall confirm 

       52

        

      
        
          


      

      that, the Holders of such Outstanding Securities and any coupons appertaining thereto will not recognize income, gain or loss for Federal income tax purposes as a result of such defeasance and
        will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such defeasance had not occurred. 

      (e) In the case of an election under Section 1303, the Company shall have
        delivered to the Trustee an Opinion of Counsel to the effect that the Holders of such Outstanding Securities and any coupons appertaining thereto will not recognize income, gain or loss for Federal income tax purposes as a result of such covenant
        defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such covenant defeasance had not occurred. 

      (f) The Company shall have delivered to the Trustee an Officers’ Certificate
        and an Opinion of Counsel, each stating that all conditions precedent to the defeasance under Section 1302 or the covenant defeasance under Section 1303 (as the case may be) have been complied with and an Opinion of Counsel to the effect that
        either (i) as a result of a deposit pursuant to subsection (a) above and the related exercise of the Company’s option under Section 1302 or Section 1303 (as the case may be) registration is not required under the Investment Company Act of 1940, as
        amended, by the Company, with respect to the trust funds representing such deposit or by the Trustee for such trust funds or (ii) all necessary registrations under said Act have been effected. 

      (g) After the 91st day following the deposit, the trust funds will not be
        subject to the effect of any applicable bankruptcy, insolvency, reorganization or similar laws affecting creditors’ rights generally. 

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

      SECTION 1305.    Deposited Money and Government
          Obligations to Be Held in Trust; Other Miscellaneous Provisions. 

      Subject to the provisions of the last paragraph of Section 1003, all money and Government Obligations (or other property as may be provided pursuant to Section 301) (including
        the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 1305, the “Trustee”) pursuant to Section 1304 in respect of any Outstanding Securities of any series and any coupons
        appertaining thereto shall be held in trust and applied by the Trustee, in accordance with the provisions of such Securities and any coupons appertaining thereto and this Indenture, to the payment, either directly or through any Paying Agent
        (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Holders of such Securities and any coupons appertaining thereto of all sums due and to become due thereon in respect of principal (and premium or Make-Whole
        Amount, if any) and interest and Additional Amounts, if any, but such money need not be segregated from other funds except to the extent required by law.

      Unless otherwise specified with respect to any Security pursuant to Section 301, if, after a deposit referred to in Section 1304(a) has been made, (a) the Holder of a Security
        in respect of which such deposit was made is entitled to, and does, elect pursuant to Section 301 or the terms of such Security to receive payment in a currency or currency unit other than that in which the deposit pursuant to Section 1304(a) has
        been made in respect of such Security, or (b) a Conversion Event occurs in respect of the currency or currency unit in which the deposit pursuant to Section 1304(a) has been made, the indebtedness represented by such Security and any coupons
        appertaining thereto shall be deemed to have been, and will be, fully discharged and satisfied through the payment of the principal of (and premium or Make-Whole Amount, if any), and interest, if any, on such Security as the same becomes due and
        Additional Amounts, if any, out of the proceeds yielded by converting (from time to time as specified below in the case of any such election) the amount or other property deposited in respect of such Security into the currency or currency unit in
        which such Security becomes payable as a result of such election or Conversion Event based on the applicable market exchange rate for such currency or currency unit in effect on the second Business Day prior to each payment date, except, with
        respect to a Conversion Event, for such currency or currency unit in effect (as nearly as feasible) at the time of the Conversion Event.

      53

      

      
        
          


      

      The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the Government Obligations deposited pursuant to
        Section 1304 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 such Outstanding Securities and any coupons appertaining thereto.

      Anything in this Article to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon Company Request any money or Government
        Obligations (or other property and any proceeds therefrom) held by it as provided in Section 1304 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 a defeasance or covenant defeasance, as applicable, in accordance with this Article.

        setting forth in reasonable detail the action proposed to be taken at the meeting, and the Trustee shall not have made the first publication of the notice of such meeting within 21 days after receipt of such request or shall not thereafter proceed
         to cause the meeting to be held as provided herein, then the Company or the Holders of Securities of such series in the amount above specified, as the case may be, may determine the time and the place in the City of Olympia, Washington for such
        meeting and may call such meeting for such purposes by giving notice thereof as provided in subsection (a) of this Section.

      SECTION 1403.    Persons Entitled to Vote at
          Meetings. 

      To be entitled to vote at any meeting of Holders of Securities of any series, a Person shall be (1) a Holder of one or more Outstanding Securities of such series, or (2) a
        Person appointed by an instrument in writing as proxy for a Holder or Holders of one or more Outstanding Securities of such series by such Holder or Holders. The only Persons who shall be entitled to be present or to speak at any meeting of Holders
        of Securities of any series shall be the Persons entitled to vote at such meeting and their counsel, any representatives of the Trustee and its counsel and any representatives of the Company and its counsel.

      SECTION 1404.    Quorum; Action. 

      The Persons entitled to vote a majority in principal amount of the Outstanding Securities of a series shall constitute a quorum for a meeting of Holders of Securities of such
        series; provided, however, that if any action is to be taken at such meeting with respect to a consent or waiver which this Indenture expressly provides may be given by the Holders of not less than a specified percentage in principal amount of the
        Outstanding Securities of a series, 

       54

      

      
        
          


      

      the Persons entitled to vote such specified percentage in principal amount of the Outstanding Securities of such series shall constitute a quorum. In the absence of a quorum within 30 minutes
        after the time appointed for any such meeting, the meeting shall, if convened at the request of Holders of Securities of such series, be dissolved. In any other case the meeting may be adjourned for a period of not less than 10 days as determined
        by the chairman of the meeting prior to the adjournment of such meeting. In the absence of a quorum at any such adjourned meeting, such adjourned meeting may be further adjourned for a period of not less than 10 days as determined by the chairman
        of the meeting prior to the adjournment of such adjourned meeting. Notice of the reconvening of any adjourned meeting shall be given as provided in Section 1402(a), except that such notice need be given only once not less than five (5) days prior
        to the date on which the meeting is scheduled to be reconvened. Notice of the reconvening of any adjourned meeting shall state expressly the percentage, as provided above, of the principal amount of the Outstanding Securities of such series which
        shall constitute a quorum. Except as limited by the proviso to Section 902, any resolution presented to a meeting or adjourned meeting duly reconvened at which a quorum is present as aforesaid may be adopted by the affirmative vote of the Holders
        of a majority in aggregate principal amount of the Outstanding Securities of that series represented at such meeting; provided, however, that, except as limited by the proviso to Section 902, any resolution with respect to any request, demand,
        authorization, direction, notice, consent, waiver or other action which this Indenture expressly provides may be made, given or taken by the Holders of a specified percentage, which is less than a majority, in principal amount of the Outstanding
        Securities of a series may be adopted at a meeting or an adjourned meeting duly reconvened and at which a quorum is present as aforesaid by the affirmative vote of the Holders of such specified percentage in principal amount of the Outstanding
        Securities of that series.

      Any resolution passed or decision taken at any meeting of Holders of Securities of any series duly held in accordance with this Section shall be binding on all the Holders of
        Securities of such series and the related coupons, whether or not present or represented at the meeting.

      Notwithstanding the foregoing provisions of this Section 1404, if any action is to be taken at a meeting of Holders of Securities of any series with respect to any request,
        demand, authorization, direction, notice, consent, waiver or other action that this Indenture expressly provides may be made, given or taken by the Holders of a specified percentage in principal amount of all Outstanding Securities affected
        thereby, or of the Holders of such series and one or more additional series:

      (i) there shall be no minimum quorum requirement for such meeting; and 

      (ii)             the principal amount of the Outstanding Securities of such series that vote in favor of such request, demand, authorization, direction, notice, consent, waiver
        or other action shall be taken into account in determining  whether such request, demand, authorization, direction, notice, consent, waiver or other action has been made, given or taken under this Indenture.

      SECTION 1405.    Determination of Voting Rights;
          Conduct and Adjournment of Meetings. 

      (a) Notwithstanding any provisions of this Indenture, the Trustee may make such
        reasonable regulations as it may deem advisable for any meeting of Holders of Securities of a series in regard to proof of the holding of Securities of such series and of the appointment of proxies and in regard to the appointment and duties of
        inspectors of votes, the submission and examination of proxies, certificates and other evidence of the right to vote, and such other matters concerning the conduct of the meeting as it shall deem appropriate. Except as otherwise permitted or
        required by any such regulations, the holding of Securities shall be proved in the manner specified in Section 104 and the appointment of any proxy shall be proved in the manner specified in Section 104 or by having the signature of the Person
        executing the proxy witnessed or guaranteed by any trust company, bank or banker authorized by Section 104 to certify to the holding of Bearer Securities. Such regulations may provide that written instruments appointing proxies, regular on their
        face, may be presumed valid and genuine without the proof specified in Section 104 or other proof. 

      (b) The Trustee shall, by an instrument in writing, appoint a temporary
        chairman of the meeting, unless the meeting shall have been called by the Company or by Holders of Securities as provided in Section 1402(b), in which case the Company or the Holders of Securities of or within the series calling the meeting, as the
        case may be, shall in like manner appoint a temporary chairman. A permanent chairman and a permanent 

       55

        

      
        
          


      

      secretary of the meeting shall be elected by vote of the Persons entitled to vote a majority in principal amount of the Outstanding Securities of such series represented at the meeting. 

      (c) At any meeting each Holder of a Security of such series or proxy shall be
        entitled to one vote for each $1,000 principal amount of the Outstanding Securities of such series held or represented by him; provided, however, that no vote shall be cast or counted at any meeting in respect of any Security challenged as not
        Outstanding and ruled by the chairman of the meeting to be not Outstanding. The chairman of the meeting shall have no right to vote, except as a Holder of a Security of such series or proxy. 

      (d) Any meeting of Holders of Securities of any series duly called pursuant to
        Section 1402 at which a quorum is present may be adjourned from time to time by Persons entitled to vote a majority in principal amount of the Outstanding Securities of such series represented at the meeting, and the meeting may be held as so
        adjourned without further notice. 

      SECTION 1406.    Counting Votes and Recording Action
          of Meetings. 

      The vote upon any resolution submitted to any meeting of Holders of Securities of any series shall be by written ballots on which shall be subscribed the signatures of the
        Holders of Securities of such series or of their representatives by proxy and the principal amounts and serial numbers of the Outstanding Securities of such series held or represented by them. The permanent chairman of the meeting shall appoint two
        inspectors of votes who shall count all votes cast at the meeting for or against any resolution and who shall make and file with the secretary of the meeting their verified written reports in duplicate of all votes cast at the meeting. A record, at
        least in duplicate, of the proceedings of each meeting of Holders of Securities of any series shall be prepared by the secretary of the meeting and there shall be attached to said record the original reports of the inspectors of votes on any vote
        by ballot taken thereat and affidavits by one or more persons having knowledge of the fact, setting forth a copy of the notice of the meeting and showing that said notice was given as provided in Section 1402 and, if applicable, Section 1404. Each
        copy shall be signed and verified by the affidavits of the permanent chairman and secretary of the meeting and one such copy shall be delivered to the Company and another to the Trustee to be preserved by the Trustee, the latter to have attached
        thereto the ballots voted at the meeting. Any record so signed and verified shall be conclusive evidence of the matters therein stated.

      SECTION 1407.    Evidence of Action Taken by
          Holders. 

      Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by a specified percentage in principal
        amount of the Holders of any or all series may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such specified percentage of Holders in person or by agent duly appointed in writing; and, except as
        herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee. Proof of execution of any instrument or of a writing appointing any such agent shall be sufficient for any
        purpose of this Indenture and (subject to Article Six) conclusive in favor of the Trustee and the Company, if made in the manner provided in this Article.

      SECTION 1408.    Proof of Execution of Instruments. 

      Subject to Article Six, the execution of any instrument by a Holder or his agent or proxy may be proved in accordance with such reasonable rules and regulations as may be
        prescribed by the Trustee or in such manner as shall be satisfactory to the Trustee.

      OR TO OBTAIN INTEREST PAYABLE PRIOR TO THE EXCHANGE DATE CERTIFICATE

       

      [Insert title or sufficient description of Securities to be delivered]

       

      This is to certify that, as of the date hereof, and except as set forth below, the above-captioned Securities held by you for our account (i) are owned by person(s) that are
        not citizens or residents of the United States, domestic partnerships, domestic corporations or any estate or trust the income of which is subject to United States federal income taxation regardless of its source (“United States person(s)”),
        (ii) are owned by United States person(s) that are (a) foreign branches of United States financial institutions (financial institutions, as defined in United States Treasury Regulations Section 1.165-12(c)(1)(v) are herein referred to as “financial
        institutions”) purchasing for their own account or for resale, or (b) United States person(s) who acquired the Securities through foreign branches of United States financial institutions and who hold the Securities through such United States
        financial institutions on the date hereof (and in either case (a) or (b), each such United States financial institution hereby agrees, on its own behalf or through its agent, that you may advise                                          
                  or its agent that such financial institution will provide a certificate within a reasonable time stating that it agrees to comply with the requirements of Section 165(j)(3)(A), (B) or (C) of the United States Internal Revenue Code of
        1986, as amended, and the regulations thereunder), or (iii) are owned by a financial institution for purposes of resale during the restricted period (as defined in United States Treasury Regulations Section 1.1635(c)(2)(i)(D)(7)), and, such
        financial institution described in clause (iii) above (whether or not also described in clause (i) or (ii)), certifies that it has not acquired the Securities for purposes of resale directly or indirectly to a United States person or to a person
        within the United States or its possessions.

      As used herein, “United States” means the United States of America (including the States and the District of Columbia); and its “possessions” include Puerto Rico, the U.S.
        Virgin Islands, Guam, American Samoa, Wake Island and the Northern Mariana Islands.

      We undertake to advise you promptly by tested telex on or prior to the date on which you intend to submit your certification relating to the above-captioned Securities held by
        you for our account in accordance with your Operating Procedures if any applicable statement herein is not correct on such date, and in the absence of any such notification it may be assumed that this certification applies as of such date. This
        certificate excepts and does not relate to [U.S.$] of such interest in the above-captioned Securities in respect of which we are not able to certify and as to which we understand an exchange for an interest in a permanent global Security or an
        exchange for and delivery of definitive Securities (or, if relevant, collection of any interest) cannot be made until we do so certify.

      We understand that this certificate may be required in connection with certain tax legislation in the United States. If administrative or legal proceedings are commenced or
        threatened in connection with which this certificate is or would be relevant, we irrevocably authorize you to produce this certificate or a copy thereof to any interested party in such proceedings.

        Securities (i) is owned by person(s) that are not citizens or residents of the United States, domestic partnerships, domestic corporations or any estate or trust the income of which is subject to United States Federal income taxation regardless of
        its source (“United States person(s)”), (ii) is owned by United States person(s) that are (a) foreign branches of United States financial institutions (financial institutions, as defined in United States Treasury Regulations

        institutions and who hold the Securities through such United States financial institutions on the date hereof (and in either case (a) or (b), each such financial institution has agreed, on its own behalf or through its agent, that we may advise
                                                               or its agent that such financial institution will provide a certificate within a reasonable time stating that it agrees to comply with the requirements of Section 165(j)(3)(A), (B), or (C) of
        the Internal Revenue Code of 1986, as amended, and the regulations thereunder), or (iii) is owned by a financial institution for purposes of resale during the restricted period (as defined in United States Treasury Regulations
        Section 1.163-5(c)(2)(i)(D)(7)), and that such financial institutions described in clause (iii) above (whether or not also described in clause (i) or (ii)) have certified that they have not acquired the Securities for purposes of resale directly or

        Virgin Islands, Guam, American Samoa, Wake Island and the Northern Mariana Islands.

      We further certify that (i) we are not making available herewith for exchange (or, if relevant, collection of any interest) any portion of the temporary global Security
        representing the above-captioned Securities excepted in the above-referenced certificates of Member Organizations and (ii) as of the date hereof we have not received any notification from any of our Member Organizations to the effect that the
        statements made by such Member Organizations with respect to any portion of the part submitted herewith for exchange (or, if relevant, collection of any interest) are no longer true and cannot be relied upon as of the date hereof.

      We understand that this certification is required in connection with certain tax legislation in the United States. If administrative or legal proceedings are commenced or
        threatened in connection with which this certificate is or would be relevant, we irrevocably authorize you to produce this certificate or a copy thereof to any interested party in such proceedings.
