        Certificate stating that all conditions precedent, if any, provided for in this Indenture 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 provision of this Indenture relating to such particular application or request,
        no additional certificate or opinion need be furnished.

       

      Every certificate or opinion with respect to compliance with a condition or covenant provided for in this Indenture shall include

       

      (3)  a statement that each individual signing such certificate or
          opinion has read such covenant or condition and the definitions herein relating thereto;

       

      (4)  a brief statement as to the nature and scope of the examination
          or investigation upon which the statements or opinions contained in such certificate or opinion are based;

       

      (5)  a statement that, in the opinion of each such individual, he has
          made such examination or investigation as is necessary to enable him to express an informed opinion as to whether or not such covenant or condition has been complied with; and

       

        

      
        7

        
          


      

      (6)  a statement as to whether, in the opinion of each such
          individual, such condition or covenant has been complied with.

       

      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 with respect 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 a certificate or opinion of, or representations by, counsel,
        unless such officer knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to matters upon which his certificate or opinion is based are erroneous. Any such certificate or Opinion
        of Counsel 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 with respect to such factual matters is in the possession
        of the Company, unless such counsel knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect 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 may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such 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, and, where it is hereby expressly required, to the Company. Such instrument or instruments (and the action
          embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient
          for any purpose of this Indenture and (subject to Section 601) conclusive in favor of the Trustee and the Company and any agent of the Trustee or the Company, if made in the manner provided in this Section.

       

      (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 the certificate of any 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 an officer of a corporation or association or a member of a partnership or an official of a public or governmental body, on behalf of such corporation, association,
          partnership, or public or governmental body or by a fiduciary, such certificate or affidavit shall also constitute sufficient proof of his authority. The fact and date of the execution by any Person of any such instrument or writing, or the
          authority of the Person executing the same, may also be proved in any other manner which the Trustee deems sufficient and in accordance with such reasonable rules as the Trustee may determine.

       

        

      
        8

        
          


      

      (c)  The ownership of Securities shall be proved by the Security Register.

       

      (d)  Any request, demand, authorization, direction, notice, consent, waiver or other
          action by the Holder of any Security shall bind every future Holder of the same Security and the Holder of every Security issued upon the transfer thereof or in exchange therefor or in lieu thereof in respect of anything done 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 Securities.

       

      SECTION 105.          Notices, etc., to Trustee and Company.

       

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

       

      (3)  the Trustee by any Holder or by the Company shall be sufficient
          for every purpose hereunder if in writing and mailed, first-class postage prepaid, to the Trustee addressed to it at its Corporate Trust Office;

       

      (4)  the Company by the Trustee or by any Holder shall be sufficient
          for every purpose hereunder if in writing and mailed, first-class postage prepaid, to the Company addressed to it at Kerr-McGee Center, Oklahoma City, Oklahoma 73102, Attention: Secretary, 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 to Holders of any event, such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed,
        first-class postage prepaid, to each Holder affected by such event, at his address as it appears in the Security Register, not later than the latest date, and not earlier than the earliest date, prescribed for the giving of such notice. In any case
        where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. 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.

       

      

      
        9

        
          


      

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

       

      SECTION 107.          Conflict with Trust Indenture Act.

       

      If any provision hereof limits, qualifies or conflicts with another provision hereof which is required to be included in this Indenture by any of the provisions of the Trust
        Indenture Act, such required provision shall control.

       

      SECTION 108.          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 109.          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 110.          Separability Clause.

       

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

       

      

      SECTION 111.          Benefits of Indenture.

       

      Nothing in this Indenture or in the Securities, 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 of Securities) any benefit or any legal or equitable right, remedy or claim under this Indenture.

       

      SECTION 112.          Governing Law.

       

      This Indenture and the Securities shall be deemed to be contracts made under the law of the State of New York and for all purposes shall be construed in accordance with the law
        of said State.

       

      SECTION 113.          Legal Holidays.

       

      In any case where any Interest Payment Date, Redemption Date or Stated Maturity of any Security shall not be a Business Day, then (notwithstanding any other provision of this
        Indenture or the Security) payment of interest or principal need not be made on such date, but may be made on the next succeeding Business Day with the same force and effect as if made on the Interest Payment Date or Redemption Date, or at the
        Stated Maturity, and no interest shall accrue for the period from and after such Interest Payment Date, Redemption Date or Stated Maturity, as the case may be.

      No recourse for the payment of principal of or interest on any Security or for any claim based on any Security or this Indenture shall be had against any director or officer or
        stockholder, past, present or future, of the Company. Any such claim against any such Person is expressly waived as a condition of, and as consideration for, the execution and delivery of this Indenture and the issue of the Securities.

       

      SECTION 115.          No Security Interest Created.

          pursuant to a Board Resolution or by a supplemental indenture as permitted by Section 201 in conformity with the provisions of this Indenture;

       

        

      
        13

        
          


      

      (b)  that the terms of such Securities have been established by or
          pursuant to a Board Resolution or by a supplemental indenture as permitted by Section 301 in conformity with the provisions of this Indenture;

       

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

       

      (d)  that all laws and requirements in respect of the execution and
          delivery by the Company of the Securities have been complied with and that authentication and delivery of the Securities by the Trustee will not violate the terms of the Indenture.

       

      The Trustee shall have the right to decline to authenticate and deliver any Securities under this Section if the Trustee, being advised by counsel, determines that such action
        may not lawfully be taken or if the Trustee in good faith by its Board of Directors or trustees, executive committee, or a trust committee of directors or trustees and/or vice presidents shall determine that such action would expose the Trustee to
        personal liability to existing Holders.

       

      Each Security shall be dated the date of its authentication.

       

      SECTION 304.         Execution of Securities.  The Securities shall be signed in the
        name and on behalf of the Company by the manual or facsimile signatures of the Chairman of the Board or its Vice Chairman or its President or one of its Vice Presidents under its corporate seal (which may be printed, engraved or otherwise
        reproduced thereon, by facsimile or otherwise), and attested by its Treasurer or Secretary or one of its Assistant Treasurers or Assistant Secretaries. Only such Securities as shall bear thereon a certificate of authentication substantially in the
        form hereinbefore recited, executed by the Trustee, shall be entitled to the benefits of this Indenture or be valid or obligatory for any purpose. Such certificate by the Trustee upon any Security executed by the Company shall be conclusive
        evidence that the Security so authenticated has been duly authenticated and delivered hereunder and that the Holder is entitled to the benefits of this Indenture.

       

      In case any officer of the Company who shall have signed any of the Securities shall cease to be such officer before the Securities so signed shall have been authenticated and
        delivered by the Trustee, or disposed of by the Company, such Securities nevertheless may be authenticated and delivered or disposed of as though the person who signed such Securities had not ceased to be such officer of the Company; and any
        Security may be signed on behalf of the Company by such persons as, at the actual date of the execution of such Security, shall be the proper officers of the Company, although at the date of the execution of this Indenture any such person was not
        such an officer.

      SECTION 305.         Exchange and Registration of Transfer of Securities.  Securities
        of any series may be exchanged for a like aggregate principal amount of Securities of the same series of other authorized denominations. Securities to be exchanged shall be surrendered at the office or agency to be maintained by the Company in the
        Borough of Manhattan, The City of New York, as provided in Section 1002. The Trustee is hereby appointed “Security Registrar” for the purpose of the registration of Securities and of transfer of Securities in the Security Register as herein
        provided. The Company shall cause to be kept at the Corporate Trust Office of the Trustee a register for each series of Securities issued hereunder (hereinafter collectively referred to as the “Security Register”) in which, subject to such
        reasonable regulations as it may prescribe, the Company shall provide for the registration of Securities and the transfer of Securities as in this Article Three provided. The Security Register shall be in written form or in any other form capable
        of being converted into written form within a reasonable time. Upon due presentment for registration of transfer of any Security of any series at such office or agency, the Company shall execute and the Trustee shall register, authenticate and
        deliver in the name of the transferee or transferees a new Security or Securities of the same series for an equal aggregate principal amount.

       

      All Securities presented for registration of transfer or for exchange, redemption or payment shall (if so required by the Company or the Security Registrar) be duly endorsed
        by, or be accompanied by a written instrument or instruments of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the registered Holder or his attorney duly authorized in writing.

       

      No service charge shall be made for any exchange or registration of transfer 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 therewith.

       

      The Company shall not be required to exchange or register the transfer of (a) any Securities of any series for a period of 15 days next preceding any selection of Securities of
        that series to be redeemed, or (b) any Securities selected, called or being called for redemption except, in the case of any Security to be redeemed in part, the portion thereof not so to be redeemed.

       

      SECTION 306.         Mutilated, Destroyed, Lost or Stolen Securities.  In case any
        temporary or definitive Security shall become mutilated or be destroyed, lost or stolen, the Company in the case of a mutilated Security shall, and in the case of a lost, stolen or destroyed Security may in its discretion, execute, and upon its
        request the Trustee shall authenticate and deliver, a new Security of the same series bearing a number, letter or other distinguishing symbol not contemporaneously outstanding, in exchange and substitution for the mutilated Security, or in lieu of
        and in substitution for the Security so destroyed, lost or stolen, or if any such Security shall have matured or shall be about to mature, instead of issuing a substituted Security, the Company may pay or authorize the payment of the same without
        surrender thereof (except in the case of a mutilated Security). In every case the applicant for a substituted Security shall furnish to the Company and to the Trustee such security or indemnity as may be required by them to save each of them
        harmless, and, in every case of destruction, loss or theft, the applicant shall also furnish to the Company and to the Trustee evidence to their satisfaction of the destruction, loss or theft of such Security and of the ownership thereof.

       

      

      
        15

        
          


      

      The Trustee may authenticate any such substituted Security and deliver the same upon the written request or authorization of any officer of the Company. Upon the issuance of
        any substituted Security, 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 connected therewith and in addition a further sum not
        exceeding two dollars for each Security so issued in substitution.

       

      Every substituted Security issued pursuant to the provisions of this Section 306 by virtue of the fact that any Security is destroyed, lost or stolen shall constitute an
        additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security shall be found at any time, and shall be entitled to all the benefits. of this Indenture equally and proportionately with any and all other
        Securities of that series duly issued hereunder. All Securities shall be held and owned upon the express condition that the foregoing provisions are exclusive with respect to the replacement or payment of mutilated, destroyed, lost or stolen
        Securities and shall preclude (to the extent lawful) any and all other rights or remedies with respect to the replacement or payment of negotiable instruments or other securities without their surrender.

       

      SECTION 307.         Temporary Securities.  Pending the preparation of definitive
        Securities of any series the Company may execute and the Trustee shall authenticate and deliver temporary Securities (printed or lithographed). Temporary Securities shall be issuable in any authorized denomination and substantially in the form of
        the definitive Securities but with such omissions, insertions and variations as may be appropriate for temporary Securities, all as may be determined by the Company. Every such temporary Security shall be executed by the Company and shall be
        authenticated by the Trustee upon the same conditions and in substantially the same manner, and with the same effect, as the definitive Securities. Without unreasonable delay the Company will execute and deliver to the Trustee definitive Securities
        of such series and thereupon any or all temporary Securities of such series may be surrendered in exchange therefor, at the Corporate Trust Office of the Trustee, and the Trustee shall authenticate and deliver in exchange for such temporary
        Securities an equal aggregate principal amount of definitive Securities. Such exchange shall be made by the Company at its own expense and without any charge therefor except that in case of any such exchange involving any registration of transfer
        the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto. Until so exchanged, the temporary Securities shall in all respects be entitled to the same benefits under
        this Indenture as definitive Securities authenticated and delivered hereunder.

       

      SECTION 308.          Payment of Interest; Interest Rights Preserved.

       

      Interest on any Security which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name that Security (or
        one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest.

       

      

      
        16

        
          


      

      Any interest on any Security which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date or within 30 days thereafter (herein called
        “Defaulted Interest”) shall forthwith cease to be payable to the registered Holder on the relevant Regular Record Date by virtue of having been such Holder; and such Defaulted Interest may be paid by the Company, at its election in each ease, as
        provided in clause (1) or (2) below:

       

      (3)  The Company may elect to make payment of any Defaulted Interest
          to the Persons in whose names. the Securities (or their respective Predecessor Securities) are registered at the close of business on a Special Record Date for the
          payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security and the date of the proposed payment, and
          at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior
          to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this clause provided. Thereupon the. Trustee shall fix a Special Record Date for the
          payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The
          Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be mailed,
          first-class postage prepaid, to each Holder at his address as it appears in the Security Register not less than 10 days prior to such Special Record Date. The Trustee may, in its discretion, in the name and at the expense of the Company, cause a
          similar notice to be published at least once in a newspaper, customarily published in the English language on each Business Day and of general circulation in the Borough of Manhattan, The City of New York, but such publication shall not be a
          condition precedent to the establishment of 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 Securities (or their respective Predecessor Securities) are registered on such Special Record Date and shall no longer be payable pursuant to the following clause (2).

       

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

       

          

      
        17

        
          


      

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

       

      SECTION 309.          Persons Deemed Owners.

       

      Prior to due presentment of a Security for registration of transfer, the Company, the Trustee, the Authenticating Agent and any agent of the Company or the Trustee may treat
        the Person in whose name any Security is registered as the owner of such Security for the purpose of receiving payment of principal of, and (subject to Section 308) interest on, such Security and for all other purposes whatsoever, whether or not
        such Security be overdue, and neither the Company, the Trustee, the Authenticating Agent nor any agent of the Company or the Trustee shall be affected by notice to the contrary.

       

      SECTION 310.          Cancellation.

       

      All Securities surrendered for payment, redemption, registration of transfer or exchange shall, if surrendered to any Person other than the Trustee, be delivered to the
        Trustee, and any such Securities and Securities surrendered directly to the Trustee for any such purpose shall be promptly cancelled by it. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated
        and delivered hereunder which the Company may have acquired in any manner whatsoever, and all Securities so delivered shall be promptly cancelled by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities
        cancelled as provided in this Section, except as expressly permitted by this Indenture. All cancelled Securities held by the Trustee shall be disposed of as directed by a Company Order.

       

      SECTION 311.          Computation of Interest.

       

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

      SECTION 401.          Satisfaction and Discharge of Indenture.

       

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

       

      (3)  either

       

      (A)  all Securities theretofore authenticated and delivered (other
          than (i) Securities which have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 306 and (ii) Securities for whose payment money has theretofore been deposited in trust or segregated and held in trust by
          the Company and thereafter repaid to the Company or discharged from such trust, as provided in Section 1003) have been delivered to the Trustee for cancellation; or

       

        

      
        18

        
          


      

      (B)  all such Securities not theretofore delivered to the Trustee for
          cancellation

       

      (i)  have become due and payable, or

          one year, or

       

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

       

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

       

      (5)  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 have been complied with.

       

      Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 607 and the obligations of the Trustee to any Authenticating Agent under Section 614 shall
        survive.

       

      SECTION 402.          Application of Trust Money.

       

      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 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, if any) and interest for whose payment
        such money has been deposited with the Trustee; but such money need not be segregated from other funds except to the extent required by law.

        REMEDIES

       

      SECTION 501.          Events of Default.

       

      “Event of Default”, wherever used
          herein with respect to Securities of any series, means any one of the following events and such other events as may be established with respect to the Securities of that series as contemplated by Section 301 hereof (whatever the reasons for such
          Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body):

       

      (a)  default in the payment of any instalment of interest upon any
          Security of that series as and when the same shall become due and payable, and continuance of such default for a period of 30 days; or

       

      (b)  default in the payment of the principal of and premium, if any,
          on any Security of that series as and when the same shall become due and payable either at Maturity, upon redemption, by declaration, repayment or otherwise; or

       

      (c)  default in the payment of any sinking fund instalment as and when
          the same shall become due and payable by the terms of a Security of that series; or

       

      (d)  failure on the part of the Company duly to observe or perform any
          other of the covenants or agreements on the part of the Company in this Indenture (other than those set forth exclusively in the terms of any particular series of Securities established as contemplated in this Indenture) continued for a period of
          60 days after the date on which written notice of such failure, requiring the Company to remedy the same, shall have been given to the Company by the Trustee, or to the Company and the Trustee by the Holders of at least 25 percent in aggregate
          principal amount of the Securities at the time Outstanding and stating that such notice is a “Notice of Default” hereunder; or

       

      (e)  a court having jurisdiction in the premises shall enter a decree
          or order for relief in respect of the Company in an involuntary case under any applicable bankruptcy, insolvency or other similar law now or hereafter in effect, or appointing a receiver, liquidator, assignee, custodian, trustee, sequestrator (or

      SECTION 502.          Acceleration of Maturity; Rescission and Annulment.

       

      If an Event of Default described in clauses (a), (b) or (c) or established pursuant to Section 301 with respect to Securities of any series at the time Outstanding occurs and
        is continuing, then and in each and every such case, unless the principal of all the Securities of such series shall have already become due and payable, either the Trustee or the Holders of not less than 25 percent in aggregate principal amount of
        the Securities of such series then Outstanding hereunder, by notice in writing to the Company (and to the Trustee if given by Holders), may declare the principal amount (or, if the Securities of that series are Original Issue Discount Securities,
        such portion of the principal amount as may be specified in the terms of that series) of all the Securities of such series to be due and payable immediately, and upon any such declaration the same shall become and shall be immediately due and
        payable, anything in this Indenture or in the Securities of such series contained to the contrary notwithstanding. If an Event of Default described in clauses (d), (e) or (f) occurs and is continuing, then and in each and every such case, unless
        the principal of all the Securities shall have already become due and payable, either the Trustee or the Holders of not less than 25 percent in aggregate principal amount of all the Securities then Outstanding hereunder, by notice in writing to the
        Company (and to the Trustee if given by Holders), may declare the principal amount (or, if any Securities are Original Issue Discount Securities, such portion of the principal amount as may be specified in the terms thereof) of all the Securities
        then Outstanding hereunder to be due and payable immediately, and upon any such declaration the same shall become and shall be immediately due and payable, anything in this Indenture or in the Securities contained to the contrary notwithstanding.
        The foregoing provisions are, however, subject to the condition that if, at any time after the principal amount (or, if the Securities of that series are Original Issue Discount Securities, such portion of the principal amounts as may be specified
        in the terms of that series) of the Securities of any series (or of all the Securities, as the case may be) shall have been so declared due and payable, and before any judgment or decree for the payment of the moneys due shall have been obtained or
        entered as hereinafter provided, the Company shall pay or shall deposit with the Trustee a sum sufficient to pay all matured instalments of interest upon all the Securities of such series (or of all the Securities, as the case may be) and the
        principal of and premium, if any, on any and all Securities of such series (or of all the Securities, as the case may be) which shall have become due otherwise than by acceleration (with interest on overdue instalments of interest, to the extent
        that payment of such interest is enforceable under applicable law, and on such principal and premium, if any, at the rate of interest or Yield to Maturity (in the case of Original Issue Discount Securities) borne by the Securities of such series
        (or at the rates of interest or Yields to Maturity of all the Securities, as the ease may be), to the date of such payment or deposit) and the reasonable expenses of the Trustee, and any and all defaults under this Indenture, other than the
        nonpayment of principal of or premium, if any, or accrued interest on Securities of such series (or of all the Securities, as the case may be) which shall have become due by acceleration, shall have been cured or waived pursuant to Section 508 —
        then and in every such case the Holders of a majority in aggregate principal amount of the Securities of such series (or of all the Securities, as the case may be) then Outstanding, by written notice to the Company and to the Trustee, may waive all
        defaults with respect to that series (or with respect to all Securities, as the case may be) and rescind and annul such declaration and its consequences; but no such waiver or rescission and annulment shall extend to or shall affect any subsequent
        default, or shall impair any right consequent thereon.

       

      

      
        21

        
          


      

      In case the Trustee or any Holder shall have proceeded to enforce any right under this Indenture and such proceedings shall have been discontinued or abandoned because of such
        rescission or annulment or for any other reason or shall have been determined adversely to the Trustee or to such Holder, then and in every such case the Company and the Trustee and the Holders shall be restored respectively to their several
        positions and rights hereunder, and all rights, remedies and powers of the Company and the Trustee and the Holders shall continue as though no such proceeding had been taken.

       

      

      SECTION 503.         Payment of Securities on Default; Suit Therefor.  The Company
        covenants that (a) in case default shall be made in the payment of any instalment of interest upon any of the Securities of any series as and when the same shall become due and payable, and such default shall have continued for a period of 30 days,
        or (b) in case default shall be made in the payment of the principal of and premium, if any, on any of the Securities of any series as and when the same shall become due and payable, whether at maturity of the Securities of that series or upon
        redemption or by declaration, repayment or otherwise — then, upon demand of the Trustee, the Company will pay to the Trustee, for the benefit of the Holders of the Securities of that series, the whole amount that then shall have become due and
        payable on all such Securities of that series for principal and premium, if any, or interest, or both, as the case may be, with interest upon the overdue principal and (to the extent that payment of such interest is enforceable under applicable
        law) upon the overdue instalments of interest at the rate or Yield to Maturity (in the case of Original Issue Discount Securities) borne by the Securities of that series; and, in addition thereto, such further amount as shall be sufficient to cover
        the costs and expenses of collection, including reasonable compensation to the Trustee, its agents, attorneys and counsel, and any expenses or liabilities incurred by the Trustee hereunder other than through its negligence or bad faith.

       

      In case the Company shall fail to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, shall be entitled and empowered
        to institute any actions or proceedings at law or in equity for the collection of the sums so due and unpaid, and may prosecute any such action or proceeding to judgment or final decree, and may enforce any such judgment or final decree against the
        Company or any other obligor upon such Securities and collect in the manner provided by law out of the property of the Company or any other obligor upon such Securities wherever situated the moneys adjudged or decreed to be payable.

       

      

      
        22

        
          


      

      In case there shall be pending proceedings for the bankruptcy or for the reorganization of the Company or any other obligor on the Securities of any series under any applicable
        bankruptcy, insolvency or similar law, or in case a receiver or trustee shall have been appointed for the property of the Company or such other obligor, or in the case of any other similar judicial proceedings relative to the Company or other
        obligor upon the Securities of any series, or to the creditors or property of the Company or such other obligor, 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 pursuant to the provisions of this Section 503, shall be entitled and empowered, by intervention in such proceedings or otherwise, to file and prove a
        claim or claims for the whole amount of principal (and premium, if any) and interest (or, if the Securities of that series are Original Issue Discount Securities, such portion of the principal amount as may be specified in the terms of that series)
        owing and unpaid in respect of the Securities of any series and, in case of any judicial proceedings, to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee and of the
        Holders allowed in such judicial proceedings relative to the Company or any other obligor on the Securities of any series, its or their creditors, or its or their property, and to collect and receive any moneys or other property payable or
        deliverable on any such claims, and to distribute the same after the deduction of its charges and expenses; and any receiver, assignee or trustee in bankruptcy or reorganization is hereby authorized by each of the Holders to make such payments to
        the Trustee, and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for compensation and expenses, including counsel fees incurred by it up to the date of
        such distribution. To the extent that such payment of reasonable compensation, expenses and counsel fees out of the estate in any such proceedings shall be denied for any reason, payment of the same shall be secured by a lien on, and shall be paid
        out of, any and all distributions, dividends, moneys, securities and other property which the Holders of the Securities of any series may be entitled to receive in such proceedings, whether in liquidation or under any plan of reorganization or
        arrangement or otherwise.

       

      All rights of action and of asserting claims under this Indenture, or under any of the Securities, may be enforced by the Trustee without the possession of any of the
        Securities, or the production thereof on any trial or other proceeding relative thereto, and any such suit or proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall
        be for the ratable benefit of the Holders of all the Securities in respect of which such action was taken.

       

      SECTION 504.          Application of Moneys Collected by Trustee.  Any moneys
        collected by the Trustee under this Article Five shall be applied in the order following, at the date or dates fixed by the Trustee for the distribution of such moneys, upon presentation of the several Securities in respect of which moneys have
        been collected, and stamping thereon the payment, if only partially paid, and upon surrender thereof if fully paid:

       

      FIRST: To the payment of costs and expenses of collection and reasonable compensation to the Trustee, its agents, attorneys and counsel, and of all other
        expenses and liabilities incurred, and all advances made, by the Trustee except as a result of its negligence or bad faith;

       

      SECOND: In case the principal of the Outstanding Securities in respect of which such moneys have been collected shall not have become due and be unpaid, to
        the payment of interest on the Securities of that series, in the order of the maturity of the instalments of such interest, with interest (to the extent that such interest has been collected by the Trustee) upon the overdue instalments of interest
        at the rate or Yield to Maturity (in the case of Original Issue Discount Securities) borne by the Securities of that series, such payments to be made ratably to the persons entitled thereto;

       

      

      
        23

        
          


      

      THIRD: In case the principal of the outstanding Securities in respect of which such moneys have been collected shall have become due, by declaration or
        otherwise, to the payment of the whole amount then owing and unpaid upon the Securities of that series for principal and premium, if any, and interest, with interest on the overdue principal and premium, if any, and (to the extent that such
        interest has been collected by the Trustee) upon overdue instalments of interest at the rate or Yield to Maturity (in the case of Original Issue Discount Securities) borne by the Securities of that series; and in case such moneys shall be
        insufficient to pay in full the whole amounts so due and unpaid upon the Securities of that series, then to the payment of such principal and premium, if any, and interest without preference or priority of principal and premium, if any, over
        interest, or of interest over principal and premium, if any, or of any instalment of interest over any other instalment of interest, or of any Security of that series over any other Security of that series, ratably to the aggregate of such
        principal and premium, if any, and accrued and unpaid interest.

       

      Any surplus then remaining shall be paid to the Company or to such other Person as shall be entitled to receive it.

       

      SECTION 505.         Proceedings by Holders.  No Holder of any Security of any series
        shall have any right by virtue of or by availing of any provision of this Indenture to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Indenture or for the appointment of a receiver or trustee, or
        for any other remedy hereunder, unless such Holder previously shall have given to the Trustee written notice of default and of the continuance thereof, as hereinbefore provided,. and unless also the Holders of not less than 25 percent in aggregate
        principal amount of the Securities of that series then Outstanding, or, in the case of any Event of Default described in clause (d), (e) or (f) of Section 501, 25 percent in aggregate principal amount of all Securities then Outstanding, shall have
        made written request upon the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder and shall have offered to the Trustee such reasonable indemnity as it may require against the costs, expenses and liabilities to
        be incurred therein or thereby, and the Trustee for 60 days after its receipt of such notice, request and offer of indemnity, shall have neglected or refused to institute any such action, suit or proceeding, it being understood and intended, and
        being expressly covenanted by the taker and Holder of every Security with every other taker and Holder and the Trustee, that no one or more 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 Holder, or to obtain or seek to obtain priority over or preference to any other such Holder, or to enforce any right under this Indenture, except in the manner herein provided and
        for the equal, ratable and common benefit of all such Holders.

       

      

      
        24

        
          


      

      Notwithstanding any other provisions in this Indenture, however, the right of any Holder of any Security to receive payment of the principal of and premium, if any, and
        interest on such Security, on or after the respective due dates expressed in such Security, or to institute suit for the enforcement of any such payment on or after such respective dates shall not be impaired or affected without the consent of such
        Holder.

       

      SECTION 506.         Proceedings by Trustee.  In case of an Event of Default
        hereunder the Trustee may in its discretion proceed to protect and enforce the rights vested in it by this Indenture by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any of such rights, either
        by suit in equity or by action at law or by proceeding in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement contained in this Indenture or in aid of the exercise of any power granted in this Indenture, or to
        enforce any other legal or equitable right vested in the Trustee by this Indenture or by law.

       

      SECTION 507.         Remedies Cumulative and Continuing.  All powers and remedies
        given by this Article Five to the Trustee or to the Holders shall, to the extent permitted by law, be deemed cumulative and not exclusive of any thereof or of any other powers and remedies available to the Trustee or the Holders, by judicial
        proceedings or otherwise, to enforce the performance or observance of the covenants and agreements contained in this Indenture, and no delay or omission of the Trustee or of any Holder to exercise any right or power accruing upon any default
        occurring and continuing as aforesaid shall impair any such right or power, or shall be construed to be a waiver of any such default or an acquiescence therein; and, subject to the provisions of Section 505, every power and remedy given by this
        Article Five or by law to the Trustee or to the Holders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the Holders.

       

      SECTION 508.         Direction of Proceedings and Waiver of Defaults by Majority of Holders. 
        The Holders of a majority in aggregate principal amount of the Securities of all series at the time Outstanding 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, however, that (subject to the provisions of
        Section 601) the Trustee shall have the right to decline to follow any such direction if the Trustee, being advised by counsel, determines that the action or proceeding so directed may not lawfully be taken or if the Trustee in good faith by its
        board of directors or trustee, executive committee, or a trust committee of directors or trustees and/or Responsible Officers shall determine that the action or proceedings so directed would involve the Trustee in personal liability. Subject to
        Section 502, the Holders of a majority in aggregate principal amount of the Securities of that series at the time Outstanding may on behalf of the Holders of all of the Securities of that series waive any past default or Event of Default described
        in clauses (a), (b) or (c) of Section 501, or any other Event of Default for such series specified in the terms thereof as contemplated by Section 301 (or, in the case of an event specified in clause (d), (e) or (f) of Section 501, the Holders of a
        majority in aggregate principal amount of all the Securities then Outstanding may waive any such default or Event of Default), and its consequences except a default in the payment of interest, or premium, if any, on, or the principal of any of the
        principal of any of the Securities. Upon any such. waiver the Company, the Trustee and the Holders of the Securities of that series (or of all of the Securities, as
        the case may be) shall be restored to their former positions and rights hereunder, respectively; but no such waiver shall extend to any subsequent or other default or Event of Default or impair any right consequent thereon. Whenever any default or
        Event of Default hereunder shall have been waived as permitted by this. Section 508, said default or Event of Default shall for all purposes of the Securities of that series and this Indenture be deemed to have been cured and to be not continuing.

      SECTION 509.         Undertaking to Pay 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 509 shall not apply to any suit instituted by the Trustee, to
        any suit instituted by any Holder of the Securities of any series or group of such Holders, holding in the aggregate more than ten percent in principal amount of the Outstanding Securities of that series (or, in the case of any suit relating to or
        arising under clause (d), (e) or (f) of Section 501, ten percent in principal amount of the aggregate Outstanding Securities) or to any suit instituted by any Holder for the enforcement of the payment of the principal of or premium, if any, or
        interest on any Security against the Company on or after the due date expressed in such Security.

      (4)  in the absence of bad faith on its part, the Trustee may
          conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but in the case of any such
          certificates or opinions which by any provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this
          Indenture.

       

        

      
        26

        
          


      

      (b)  In case an Event of Default with respect to the Securities of a series has occurred
          and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture with respect to such series, and use the same degree of care and skill in their exercise, as a prudent man would exercise or use under the
          circumstances in the conduct of his own affairs.

       

      (c)  No provision of this Indenture shall be construed to relieve the Trustee from
          liability for its own negligent action, its own negligent failure to act, or its own wilful misconduct, except that

       

      (3)  this Subsection shall not be construed to limit the effect of
          Subsection (a) of this Section;

       

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

          or omitted to be taken by it in good faith in accordance with the direction of the Holders pursuant to Section 508 relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any
          trust or power conferred upon the Trustee, under this Indenture; and

       

      (6)  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 adequate indemnity against such risk or liability is not reasonably assured to it.

       

      (d)  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 602.          Notice of Defaults.

        Series, as their names and addresses appear in the Security Register, notice of all defaults with respect to that Series known to the Trustee, unless such defaults shall have been cured or waived before the giving of such notice; provided, however, that, except in the case of a default in the payment of the principal of or premium, if any, or interest on any of the Securities of such series or in the making of any sinking fund payment
        with respect to such series, the Trustee shall be protected in withholding such notice if and so long as the board of directors, the executive committee or a trust committee of directors and/or Responsible Officers of the Trustee in good faith
        determines that the withholding of such notice is in the interests of the Holders; and provided, further, that in the case of any default of the character specified in clause (d) of Section 501 no such
        notice to Holders  shall be given until at least 30 days after the occurrence thereof. For the purpose of this Section, the term “default” means any event which is, or after notice or lapse of time or both would become, an Event of Default.

        indenture or indentures which are so likely to involve a material conflict of interest as to make it necessary in the public interest or for the protection of investors to disqualify the. Trustee from acting as such under this Indenture and such
        other indenture or indentures, or

       

      (ii) the Company shall have sustained the burden of proving, on application to the Commission and after opportunity for hearing thereon, that trusteeship
        under this Indenture and such other indenture or indentures is not so likely to involve a material conflict of interest as to make it necessary in the public interest or for the protection of investors to disqualify the Trustee from acting as such
        under one of such indentures;

       

      (2)  the Trustee or any of its directors or executive officers is an
          obligor upon the Securities of any series issued under this Indenture or an underwriter for the Company;

          a director or an executive officer, or both, of the Company but may not be at the same time an executive officer of both the Trustee and the Company; (ii) if and so long as the number of directors of the Trustee in office is more than nine, one
          additional individual may be a director or an executive officer, or both, of the Trustee and a director of the Company; and (iii) the Trustee may be designated by the Company or by any underwriter for the Company to act in the capacity of
          transfer agent, registrar, custodian, paying agent, fiscal agent, escrow agent, or depositary, or in any other similar capacity, or, subject to the provisions of paragraph (1) of this Subsection, to act as trustee, whether under an indenture or
          otherwise;

       

      (5)  10% or more of the voting securities of the Trustee is

      (7)  the Trustee is the beneficial owner of, or holds as collateral
          security for an obligation which is in default (as hereinafter in this Subsection defined), 5% or more of the voting securities of any person who, to the knowledge of the Trustee, owns 10% or more of the voting securities of, or controls directly
          or indirectly or is under direct or indirect common control with, the Company;

       

      (8)  the Trustee is the beneficial owner of, or holds as collateral

        31

        
          


      

      (9)  the Trustee owns, on May 15 in any calendar year, in the capacity
          of executor, administrator, testamentary or inter vivos trustee, guardian, committee or conservator, or in any other similar capacity, an aggregate of 25% or more of the voting securities, or of any class of security, of any person, the
          beneficial ownership of a specified percentage of which would have constituted a conflicting interest under paragraph (6), (7) or (8) of this Subsection. As to any such securities of which the Trustee acquired ownership through becoming executor,
          administrator, or testamentary trustee of an estate which included them, the provisions of the preceding sentence shall not apply, for a period of two years. from the date of such acquisition, to the extent that such securities included in such
          estate do not exceed 25% of such voting securities or 25% of any such class of security. Promptly after May 15 in each calendar year, the Trustee shall make a check of its holdings of such securities in any of the above-mentioned capacities as of
          such May 15. If the Company fails to make payment in full of the principal of or interest on, any of the Securities when and as the same becomes due and payable, and such failure continues for 30 days thereafter, the Trustee shall make a prompt
          check of its holding of such securities in any of the above-mentioned capacities as of the date of the expiration of such 30-day period, and after such date, notwithstanding the foregoing provisions of this paragraph, all such securities so held
          by the Trustee, with sole or joint control over such securities vested in it, shall, but only so long as such failure shall continue, be considered as though beneficially owned by the Trustee for the purposes of paragraphs (6), (7) and (8) of
          this Subsection.

       

      The specification of percentages in paragraphs (5) to (9), inclusive, of this Subsection shall not be construed as indicating that the ownership of such percentages of the
        securities of a person is or is not necessary or sufficient to constitute direct or indirect control for the purposes of paragraph (3) or (7) of this Subsection.

       

      For the purposes of paragraphs (6), (7), (8) and (9) of this Subsection only, (i) the terms “security” and “securities” shall include only such securities as are generally
        known as corporate securities, but shall not include any note or other evidence of indebtedness issued to evidence any obligation to repay moneys lent to a person by one or more banks, trust companies or banking firms, or any certificate of
        interest or participation in any such note or evidence of indebtedness; (ii) an obligation shall be deemed to be “in default” when a default in payment of principal shall have continued for 30 days or more and shall not have been cured; and (iii)
        the Trustee shall not be deemed to be the owner or holder of (A) any security which it holds as collateral security, as trustee or otherwise, for an obligation which is not in default as defined in clause (ii) above, or (B) any security which it
        holds as collateral security under this Indenture, irrespective of any default hereunder, or (C) any security which it holds as agent for collection, or as custodian, escrow agent, or depositary, or in any similar representative capacity.

          means every person who, within three years prior to the time as of which the determination is made, has purchased from the Company with a view to, or has offered or sold for the Company in connection with, the distribution of any security of the
          Company outstanding at such time, or has participated or has had a direct. or indirect participation in any such undertaking, or has participated or has had a participation in the direct or indirect underwriting of any such undertaking, but such
          term shall not include a person whose interest was limited to a commission from an underwriter or dealer not in excess of the usual and customary distributors’ or sellers’ commission.

      (4)  The term “voting security” means any security presently entitling
          the owner or holder thereof to vote in the direction or management of the affairs of a person, or any security issued under or pursuant to any trust, agreement or arrangement whereby a trustee or trustees or agent or agents for the owner or

      (e)  The percentages of voting securities and other securities specified in this Section
          shall be calculated in accordance with the following provisions:

       

      (3)  A specified percentage of the voting securities of the Trustee,
          the Company or any other person referred to in this Section (each of whom is referred to as a “person” in this paragraph) means such amount of the outstanding voting securities of such person as entitles the holder or holders thereof to cast such

          owing upon any claim as such creditor in respect of principal or interest, effected after the beginning of such four-month period and valid as against the Company and its other creditors, except any such reduction resulting from the receipt or
          disposition of any property described in paragraph (2) of this Subsection, or from the exercise of any right of set-off which the Trustee could have exercised if a petition in bankruptcy had been filed by or against the Company upon the date of
          such default; and

       

      (4)  all property received by the Trustee in respect of any claim as

          such claim by any Person (other than the Company) who is liable thereon, and (ii) the proceeds of the bona fide sale of any such claim by the Trustee to a third Person, and (iii) distributions made in cash, securities or other property in respect
          of claims filed against the Company in bankruptcy or receivership or in proceedings for reorganization pursuant to the Federal bankruptcy laws, as now or hereafter constituted, or any other Federal or State bankruptcy, insolvency or similar law;

       

      (B)  to realize, for its own account, upon any property held by it as
          security for any such claim, if such property was so held prior to the beginning of such four-month period;

       

      (C)  to realize, for its own account, but only to the extent of the
          claim hereinafter mentioned, upon any property held by it as security for any such claim, if such claim was created after the beginning of such four-month period and such property was received as security therefor simultaneously with the creation
          thereof, and if the Trustee shall sustain the burden of proving that at the time such property was so received the Trustee had no reasonable cause to believe that a default as defined in Subsection (c) of this Section would occur within four
          months; or

       

      (D)  to receive payment on any claim referred to in paragraph (B) or
          (C), against the release of any property held as security for such claim as provided in paragraph (B) or (C), as the case may be, to the extent of the fair value of such property.

        substitution shall, to the extent of the fair value of the property released, have the same status as the property released, and, to the extent that any claim referred to in any of such paragraphs is created in renewal of or in substitution for or
        for the purpose of repaying or refunding any pre-existing claim of the Trustee as such creditor, such claim shall have the same status as such pre-existing claim.

       

      

      
        38

        payments from such special account and payments of dividends on claims filed against the Company in bankruptcy or receivership or in proceedings for reorganization pursuant to the Federal bankruptcy laws, as now or hereafter constituted, or any
        other applicable Federal or State bankruptcy, insolvency or similar law, the same percentage of their respective claims, figured before crediting to the claim of the Trustee anything on account of the receipt by it from the Company of the funds and
        property in such special account and before crediting to the respective claims of the Trustee and the Holders and the holders of other indenture securities dividends on claims filed against the Company in bankruptcy or receivership or in
        proceedings for reorganization pursuant to the Federal bankruptcy laws, as now or hereafter constituted, or any other applicable Federal or State bankruptcy, insolvency or similar law, but after crediting thereon receipts on account of the

        receivership or proceedings for reorganization is pending shall have jurisdiction (i) to apportion between the Trustee and the Holders and the holders of other indenture securities, in accordance with the provisions of this paragraph, the funds and
        property held in such special account and proceeds thereof, or (ii) in lieu of such apportionment, in whole or in part, to give to the provisions of this paragraph due consideration in determining the fairness of the distributions to be made to the
        Trustee and the Holders and the holders of other indenture securities with respect to their respective claims, in which event it shall not be necessary to liquidate or to appraise the value of any securities or other property held in such special
        account or as security for any such claim, or to make a specific allocation of such distributions as between the secured and unsecured portions of such claims, or otherwise to apply the provisions of this paragraph as a mathematical formula.

       

      Any Trustee which has resigned or been removed after the beginning of such four-month period shall be subject to the provisions of this Subsection as though such resignation or
        removal had not occurred. If any Trustee has resigned or been removed prior to the beginning of such four-month period, it shall be subject to the provisions of this Subsection if and only if the following conditions exist:

       

      

      
        39

        occurred after the beginning of such four months period; and

       

      (ii)  such receipt of property or reduction of claim occurred within four months after such resignation or removal.

          indenture, or any securities or securities having a maturity of one year or more at the time of acquisition by the Trustee;

       

      (4)  advances authorized by a receivership or bankruptcy court of
          competent jurisdiction, or by this Indenture, for the purpose of preserving any property which shall at any time be subject to the lien of this Indenture or of discharging tax liens or other prior liens or encumbrances thereon, if notice of such
          advances and of the circumstances surrounding the making thereof is given to the Holders at the time and in the manner provided in this Indenture;

       

      (5)  disbursements made in the ordinary course of business in the
          capacity of trustee under an indenture, transfer agent, registrar, custodian, paying agent, fiscal agent or depositary, or other similar capacity;

       

      (6)  an indebtedness created as a result of services rendered or
          premises rented; or an indebtedness created as a result of goods or securities sold in a cash transaction as defined in Subsection (c) of this Section;

       

      (7)  the ownership of stock or of other securities of a corporation
          organized under the provisions of Section 25(a) of the Federal Reserve Act, as amended, which is directly or indirectly a creditor of the Company; or

       

      (8)  the acquisition, ownership, acceptance or negotiation of any
          drafts, bills of exchange, acceptances or obligations which fall within the classification of self-liquidating paper as defined in Subsection (c) of this Section.

       

      (c)  For the purpose of this Section only:

       

      (3)  The term “default” means any failure to make payment in full of
          the principal of or interest on any of the Securities or upon the other indenture securities when and as such principal or interest becomes due and payable.

       

      (4)  The term “other indenture securities” means securities upon which
          the Company is an obligor outstanding under any other indenture (i) under which the Trustee is also trustee, (ii) which contains provisions substantially similar to the provisions of this Section, and (iii) under which a default exists at the
          time of the apportionment of the funds and property held in such special account.

            (5)  The term “cash transaction” means any transaction in which
                full payment for goods or securities sold is made within seven days after delivery of the goods or securities in currency or in checks or other orders drawn upon banks or bankers and payable upon demand.

                exchange, acceptance or obligation which is made, drawn, negotiated or incurred by the Company for the purpose of financing the purchase, processing, manufacturing, shipment, storage or sale of goods, wares or merchandise and which is
                secured by documents evidencing title to, possession of, or a lien upon, the goods, wares or merchandise or the receivables or proceeds arising from the sale of the goods, wares or merchandise previously constituting the security, provided the security is received by the Trustee simultaneously with the creation of the creditor relationship with the Company arising from the making, drawing, negotiating or incurring of the draft,
                bill of exchange, acceptance or obligation.

              Trustee to authenticate Securities issued upon exchange, transfer or partial redemption 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. Wherever reference is made in this Indenture to the authentication and delivery of Securities by the Trustee or the Trustee’s certificate of authentication, such reference shall
              be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent. Each Authenticating Agent shall be
              acceptable to the Company and shall at all times be a 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, authorized under such laws to act as
              Authenticating Agent, having a combined capital and surplus of not less than $1,500,000 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 to 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
              without the execution or filing of any paper or any further act on the part of the Trustee or the Authenticating Agent.

              shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent which shall be acceptable to the Company and shall mail notice of such appointment to all Holders, as their
              names and addresses appear on the Security Register. 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 Trustee agrees to pay to each Authenticating Agent from time to time reasonable compensation for its services under this Section, and the Trustee shall be entitled to
              be reimbursed for such payments, subject to the provisions of Section 607.

            SECTION 701.          Company to Furnish Trustee Names and Addresses of Holders.

             

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

             

            (a)  semi-annually, (and not more than 15 days after each
                Regular Record Date of each series of Securities having such a Regular Record Date), a list, in such form as the Trustee may reasonably require, of the names and addresses of the Holders as of such Regular Record Date, and

             

            

            
              42

              
                


            

            (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,

             

            excluding from any such list names and addresses received by the Trustee in the capacity of Security
                Registrar if the Trustee is then acting in such capacity.

             

            SECTION 702.          Preservation of Information; Communications to Holders.

             

            (a)  The Trustee shall preserve, in as current a form as is reasonably practicable,
                the names and addresses of Holders contained in the most recent list furnished to the Trustee as provided in Section 701 and the names and addresses of Holders received by the Trustee in the capacity of Security Registrar if the Trustee is
                then acting in such capacity. The Trustee may destroy any list furnished to it as provided in Section 701 upon receipt of a new list so furnished.

             

            (b)  If three or more Holders ( hereinafter referred to as “applicants”) apply in
                writing to the Trustee, and furnish to the Trustee reasonable proof that each such applicant has owned a Security for a period of at least six months preceding the date of such application, and such application states that the applicants
                desire to communicate with other Holders with respect to their rights under this Indenture or under the Securities and is accompanied by a copy of the form of proxy or other communication which such applicants propose to transmit, then the
                Trustee shall, within five business days after the receipt of such application, at its election, either

             

            (i)   afford such applicants access to the information preserved
                at the time by the Trustee in accordance with Section 702(a), or

             

            (ii)  inform such applicants as to the approximate number of
                Holders whose names and addresses appear in the information preserved at the time by the Trustee in accordance with Section 702(a), and as to the approximate cost of mailing to such Holders the form, of proxy or other communication, if any,
                specified in such application.

             

            If the Trustee shall elect not to afford such applicants access to such information, the Trustee shall, upon the written request of such applicants, mail to each Holder
              whose name and address, appears in the information preserved at the time by the Trustee in accordance with Section 702(a), a copy of the form of proxy or other communication which is specified in such request, with reasonable promptness after
              a tender to the Trustee of the material to be mailed and of payment, or provision for the payment, of the reasonable expenses of mailing, unless within five days after such tender, the Trustee shall mail to such applicants and file with the
              Commission, together with a copy of the material to be mailed, a written statement to the effect that, in the opinion of the Trustee, such mailing would be contrary to the best interests of the Holders or would be in violation of applicable
              law. Such written statement shall specify the basis of such opinion. If the Commission, after opportunity for a hearing upon the objections specified in the written statement so filed, shall enter an order refusing to sustain any of such
              objections or if, after the entry of an order sustaining one or more of such objections, the Commission shall find, after notice and opportunity for hearing, that all the objections so sustained have been met and shall enter an order so
              declaring, the Trustee shall mail copies of such material to all such Holders with reasonable promptness after the entry of such order and the renewal of such tender; otherwise the Trustee shall be relieved of any obligation or duty to such
              applicants respecting their application.

            (c)  Every Holder of Securities, by receiving and holding the same, agrees with the
                Company and the Trustee that neither the Company nor the Trustee or any Authenticating Agent nor any Paying Agent nor any Security Registrar shall be held accountable by reason of the disclosure of any such information as to the names and
                addresses of the Holders in accordance with Section 702(b), 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

                that of the Debentures, on any property or funds held or collected by it as Trustee, except that the Trustee shall not be required (but may elect) to report such advances if such advances so remaining unpaid aggregate not more than 1/2 of 1% of the principal amount of the Outstanding Securities on the date of such
                report;

            (7)  any additional issue of Securities which the Trustee has
                not previously reported; and

             

            (8)  any action taken by the Trustee in the performance of its
                duties hereunder which it has not previously reported and which in its opinion materially affects the Securities, except action in respect of a default, notice of which has been or is to be withheld by the Trustee in accordance with Section

            (c)  A copy of each such report shall, at the time of such transmission to Holders,

              State thereof and such successor corporation shall expressly assume the due and punctual payment of the principal of and interest on all the Securities, according to their tenor, 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 satisfactory to the Trustee, executed and delivered to the Trustee by such corporation, and (ii) the Company or such successor
              corporation, as the case may be, shall not, immediately after such merger or consolidation, or such sale or conveyance, be in default in the performance of any such covenant or condition.

             

            SECTION 802.          Rights and Duties of Successor Corporation.

             

            In case of any such consolidation, merger, sale or conveyance and upon any such assumption by the successor corporation, such successor corporation shall succeed to and
              be substituted for the. Company, with the same effect as if it had been named herein as. the Company, and the predecessor corporation shall be relieved of any obligation under this Indenture and the Securities and, in the event of such sale

              with (or prior to) the Debt (as defined in Section 1008) secured by such Mortgage.

            SECTION 805.          Limitation on Lease of Properties as Entirety.

            (c)  to add to the covenants of the Company such further
                covenants, restrictions or conditions for the protection 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

                such purpose; or

             

            (e)  to establish the form or terms of Securities of any series
                as permitted by Sections 201 and 301; or

             

            (f)  to cure any ambiguity or to correct or supplement any
                provision contained herein or in any supplemental indenture which may be defective or inconsistent with any other provision contained herein or in any supplemental indenture, or to make such other provisions in regard to matters or
                questions arising under this Indenture which shall not adversely affect the interests of any Holder; or

             

            (g)  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

              any Security, or reduce the rate or extend the time of payment of interest thereon, or reduce the principal amount thereof or any premium thereon, or make the principal thereof or interest or premium thereon payable in any coin or currency
              other than that provided in the Securities or reduce the amount of the principal of an Original Issue Discount Security that would be due and payable upon an acceleration of the Maturity thereof pursuant to Section 502 or the amount thereof
              provable in bankruptcy pursuant to Section 503 or impair the right to institute suit for enforcement of any such payment on or after the Stated Maturity thereof (or, in the case of redemption, on or after the Redemption Date), or adversely
              affect the right of repayment, if any, at the option of the Holder without the consent of the Holder of each Security so affected, or (ii) reduce the aforesaid percentage of Securities, the Holders of which are required to consent to any such
              supplemental indenture, or the Holders of which are required for any waiver (of compliance with certain provisions of this Indenture or certain defaults hereunder and their consequences) provided for in this Indenture, without the consent of
              the Holder of each Security so affected. A supplemental indenture which changes or eliminates any covenant or other provision of this Indenture which has expressly been included solely for the benefit of one or more particular series of
              Securities, or which modifies the rights of the Holders of Securities of such series with respect to such covenant or other provision, shall be deemed not to affect the rights under this Indenture of the Holders of Securities of any other
              series.

             

            Upon the request of the Company, accompanied by a Board Resolution authorizing the execution of any such supplemental indenture, and upon the filing with the Trustee of
              evidence of the consent of Holders as aforesaid, the Trustee shall join with the Company in the execution of such supplemental indenture unless such supplemental indenture affects the Trustee’s own rights, duties or immunities under this
              Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such supplemental indenture.

            It shall not be necessary for the consent of the Holders under this Section 902 to approve the particular form of any proposed supplemental indenture, but it shall be
              sufficient if such consent shall approve the substance thereof.

             

            SECTION 903.         Compliance with Trust Indenture Act; Effect of Supplemental Indentures.  Any
              supplemental indenture executed pursuant to the provisions of this Article Nine shall comply with the Trust Indenture Act of 1939, as then in effect. Upon the execution of any supplemental indenture pursuant to the provisions of this Article
              Nine, this indenture shall be deemed to be modified and amended in accordance therewith and the respective rights, limitations of rights, obligations, duties and immunities under this Indenture of the Trustee, the Company and the Holders
              shall thereafter be determined, exercised and enforced hereunder subject in all respects to such modifications and amendments and all the terms and conditions of any such supplemental indenture shall be and be deemed to be part of the terms
              and conditions of this Indenture for any and all purposes.

             

            SECTION 904.        Notation on Securities.  Securities authenticated and delivered after the execution of
              any supplemental indenture pursuant to the provisions of this Article Nine may bear a notation in form approved by the Trustee as to any matter provided for in such supplemental indenture. If the Company or the Trustee shall so determine, new
              Securities of any series so modified as to conform, in the opinion of the Trustee and the Board of Directors, to any modification of this Indenture contained in any such supplemental indenture may be prepared and executed by the Company,
              authenticated by the Trustee and delivered in exchange for the Securities of such series then Outstanding.

             

            SECTION 905.        Evidence of Compliance of Supplemental Indenture to be Furnished Trustee.  The
              Trustee, subject to the provisions of Section 601, may receive an Officers’ Certificate and an Opinion of Counsel as conclusive evidence that any supplemental indenture executed pursuant hereto complies with the requirements of this Article
              Nine.

            SECTION 1001.        Payment of Principal and interest.

             

            The Company will duly and punctually pay the principal of, premium, if any, and interest on the Securities in accordance with the terms of the Securities and this

            The Company shall maintain in the Borough of Manhattan, The City of New York, an office or agency where Securities may be presented or surrendered for payment and an
              office or agency where Securities may be surrendered for transfer or exchange and where notices and demands to or upon the Company in respect of the Securities and this Indenture may be served. The Corporate Trust Office of the Trustee shall
              be such office of the Company in The City of New York, and the Trustee shall be the agent of the Company for all of the foregoing purposes, unless the Company shall designate and maintain some other office or agency for such purposes and give
              the Trustee written notice of the location thereof. The Company will give prompt written notice to the Trustee of any change in the location of any such office or agency. If at any time the Company shall fail to maintain any such required
              office or agency in the Borough of Manhattan, The City of New York, the Corporate Trust Office of the Trustee shall be conclusively deemed to be the agency of the Company for all such purposes,

            SECTION 1003.        Money for Security Payments to be held in Trust.

             

            If the Company shall at any time act as its own Paying Agent, it will, on or before each due date of the principal of or premium, if any, or interest on, any of the
              Securities, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay the principal or premium, if any, or interest so becoming due until such sums shall be paid to such Persons or otherwise disposed
              of as herein provided, and will promptly notify the Trustee of its action or failure so to act.

             

            Whenever the Company shall have one or more Paying Agents it will, prior to each due date of the. principal of or interest on, any Securities, deposit with a Paying Agent
              a sum sufficient. to pay the principal or premium, if any, or interest, so becoming due, such sum to be held in trust for the benefit of the Persons entitled to such principal or premium, if any, or interest, 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

             

            (3)  hold all sums held by it for the payment of the principal
                of or premium, if any, or interest on Securities 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;

             

            (4)  give the Trustee notice of any default by the Company (or
                any other obligor upon the Securities) in the making of any payment of principal or premium, if any, or interest; and

             

            (5)  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 money.

             

            

            
              51

              
                


            

            Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of or premium, if any, or interest on any
              Security and remaining unclaimed for three years after such principal or premium, if any or interest has become due and payable shall be paid to the Company on Company Request, or (if then held by the Company) shall be discharged from such
              trust; and the Holder of such Security shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability
              of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company
              cause to be published once, in a newspaper published in the English language, customarily published on each Business Day and of general circulation in the Borough of Manhattan, The City of New York, 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.        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 the Company 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 which, if unpaid, might by law become a lien upon the property
              of the Company or any Subsidiary; provided, 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.

            The Company will cause all Principal Properties to be maintained and kept in good physical condition, repair and working order and supplied with all necessary equipment
              and will cause to be made all necessary physical 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 or restrict the sale, abandonment or other disposition of any of such properties if
              such action is, in the judgment of the Company, desirable in the conduct of the business of the Company and its Subsidiaries as a whole.

             

            SECTION 1006.        Statement as to Default.

             

            The Company will deliver to the Trustee, on or before a date not more than four months after the end of each fiscal year of the Company ending after the date hereof, a
              statement (which shall not be deemed an Officers’ Certificate and need not conform with any of the provisions of Section 102) signed by the Chairman or Vice Chairman of the Board or the President or any Vice President of the Company and by
              the Treasurer or the Secretary or any Assistant Treasurer or any Assistant Secretary of the Company, stating that in the course of the performance by the signers of their duties as officers of the Company and based upon a review made under
              their supervision of the activities of the Company during such year and of the Company’s performance under this Indenture they would normally obtain knowledge whether or not the Company is in default in the performance of any covenant or
              agreement contained herein, stating whether or not they have obtained knowledge that the Company is in default in the performance of any such covenant or agreement, and if so, specifying each such default of which the signers have knowledge
              and the nature thereof.

            SECTION 1007.        Corporate Existence.

             

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

             

            SECTION 1008.        Limitation on Secured Debt.

             

            The Company will not itself, and will not permit any Restricted Subsidiary to, incur, issue, assume or guarantee any notes, bonds, debentures or other similar evidences
              of indebtedness (such Notes, bonds, debentures or other similar evidences of indebtedness being hereinafter in this Article called “Debt”), secured by pledge of, or mortgage or other lien on, any Principal Property owned or leased by the
              Company or any Restricted Subsidiary, or any shares of stock or Debt of any Restricted Subsidiary (pledges, mortgages and other liens being hereinafter in this Article called “Mortgage” or “Mortgages”), without effectively providing that the
              Securities (together with, if the Company shall so determine, any other Debt of the Company or such Restricted Subsidiary then existing or thereafter created which is not subordinated to the Securities) shall be secured equally and ratably
              with (or prior to) such secured Debt, so long as such secured Debt shall be so secured, unless, after giving effect thereto, the aggregate amount of all such secured debt (not including secured Debt permitted to be secured under clauses (1)
              to (7) below) plus the aggregate “value” (as defined in Section 1009) of all sale and leaseback transactions (as defined in Section 1009 but not including sale and leaseback transactions the proceeds of which have been or will be applied in
              accordance with Section 1009(2)) would not exceed 5% of Consolidated Net Tangible Assets; provided, however, that this Section shall not apply to, and there shall be excluded from secured Debt in any
              computation under this Section, Debt secured by:

             

            (3)  Mortgages on property of, or on any shares of stock or Debt
                of, the Company or a Restricted Subsidiary, existing on the date hereof;

             

            (4)  Mortgages on property of, or on any shares of stock or Debt
                of, any corporation existing at the time such corporation becomes a Restricted Subsidiary;

             

            

            
              53

              
                


            

            (5)  Mortgages on property of a Restricted Subsidiary securing
                exclusively indebtedness of such Subsidiary owing to the Company or any other Restricted Subsidiary;

             

            (6)  Mortgages in favor of the United States of America, or any
                State or agency thereof or of any foreign country, or any agency, department or other instrumentality thereof, to secure progress, advance or other payments pursuant to any contract or provision of any statute;

             

            (7)  Mortgages on property, shares of stock or Debt existing at
                the time of acquisition thereof (including acquisition through merger or consolidation) or to secure the payment of all or any part of the purchase price or construction cost thereof or to secure any Debt incurred prior to, at the time of,
                or within 24 months after, the acquisition of such property or shares or Debt or the completion of any such construction for the purpose of financing all or any part of the purchase price or construction cost thereof; and

             

            (8)  Mortgages on property of the Company or a Restricted
                Subsidiary to secure the payment of all or any part of the costs of exploration, drilling, mining, or development thereof for the purpose of increasing the production and sale or other disposition of oil, gas or other minerals or any
                indebtedness incurred to provide funds for all or any such purposes.

             

            (9)  any extension, renewal or replacement (or successive
                extensions, renewals or replacements), as a whole or in part, of any Mortgage referred to in the foregoing clauses (1) to (6), inclusive; provided, that (i) such extension, renewal or replacement
                Mortgage shall be limited to all or a part of the same property, shares of stock or Debt that secured the Mortgage extended, renewed or replaced (plus improvements on such property) and (ii) the Debt secured by such Mortgage at such time is
                not increased.

             

            For purposes of this Section 1008, the sale or other transfer of any interest in property of the character commonly referred to as a “production payment” shall not be
              deemed to create secured Debt.

             

            SECTION 1009.        Limitation on Sales and Leasebacks.

             

            The Company will not itself, and it will not permit any Restricted Subsidiary to, enter into any arrangement with any bank, insurance company or other lender or investor
              (not including the Company or any Restricted Subsidiary) or to which any such lender or investor is a party, providing for the leasing by the Company or any such Restricted Subsidiary for a period, including renewals, in excess of three years
              of any Principal Property owned or leased by the Company or such Restricted Subsidiary which has been or is to be sold or transferred, more than 120 days after the completion of construction and commencement of full operation thereof, by the
              Company or any such Restricted Subsidiary to such lender or investor or to any person to whom funds have been or are to be advanced by such lender or investor on the security of such Principal Property (herein referred to as a “sale and
              leaseback transaction”) unless either:

             

            

            
              54

              
                


            

            (3)  the Company or such Restricted Subsidiary could create Debt
                secured by a Mortgage pursuant to Section 1008 on the Principal Property to be leased back equal in amount to the amount realized or to be realized upon such sale and leaseback transaction without equally and ratably securing the
                Securities, or

             

            (4)  the Company within 120 days after the sale or transfer
                shall have been made by the Company or by any such Restricted Subsidiary, applies an amount equal to the value of the Principal Property so sold and leased back at the time of entering into such arrangement to the retirement of Funded Debt
                of the Company; provided, that the amount to be applied to the retirement of Funded Debt of the Company shall be reduced by (a) the principal amount of any Securities delivered within 120 days
                after such sale to the Trustee for retirement and cancellation, and (b) the principal amount of Funded Debt, other than Securities, voluntarily retired by the Company within 120 days after such sale. Notwithstanding the foregoing, no
                retirement referred to in this clause (2) may be effected by payment at maturity or pursuant to any mandatory sinking fund payment or any mandatory prepayment provision.

             

            As used in this Section 1009, the term “value” shall mean, with respect to a sale and leaseback transaction, as of any particular time an amount equal to the greater of
              (i) the net proceeds of sale of the property leased pursuant to such sale and leaseback transaction, or (ii) the fair value of such property at the time of entering into such sale and leaseback transaction as determined by the Board of
              Directors, in each case multiplied by a fraction of which the numerator is the number of full years of remaining term of the lease (without regard to renewal options) and the denominator is the full years of the full term of the lease
              (without regard to renewal options).

             

            It is understood that transactions entered into pursuant to Section 168(f)(8) of the Internal Revenue Code, as amended, are not Debt secured by a Mortgage within the
              meaning of Section 1008 or sale and leaseback transactions prohibited by this Section 1009.

             

            SECTION 1010.        Waiver of Certain Covenants.

             

            The Company may omit in any particular instance to comply with any covenant or condition set forth in Sections 1004, 1005 and 1007 through 1009, if before or after the
              time for such compliance the Holders of at least a majority in principal amount of the Securities at the time Outstanding shall, by Act of such Holders, waive such compliance in such instance, but no such waiver shall extend to or affect such
              covenant or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the duties of the Trustee in respect of any such covenant or condition shall remain in full
              force and effect.

                REDEMPTION OF SECURITIES

             

            SECTION 1101.        Applicability of Article.  The provisions of this Article shall be applicable to the
              Securities of any series which are redeemable before their maturity except as otherwise specified as contemplated by Section 301 for Securities of such series.

             

            SECTION 1102.       Notice of Redemption; Selection of Securities.  In case the Company shall desire to
              exercise the right to redeem all, or, as the case may be, any part of the Securities of any series in accordance with their terms, it shall fix a date for redemption and shall mail or cause to be mailed a notice of such redemption at least 30
              and not more than 60 days prior to the date fixed for redemption to the Holders of Securities of such series so to be redeemed as a whole or in part at their last addresses as the same appear on the Security Register. Such mailing shall be by
              first class mail. The notice if mailed in the manner herein provided shall be conclusively presumed to have been duly given, whether or not the Holder receives such notice. In any case, failure to give such notice by mail or any defect in the
              notice to the Holder of any Security of a series designated for redemption as a whole or in part shall not affect the validity of the proceedings for the redemption of any other Security of such series.

             

            Each such notice of redemption shall specify the date fixed for redemption, the redemption price at which Securities of such series are to be redeemed, the place or
              places of payment, that payment will be made upon presentation and surrender of such Securities, that any interest accrued to the date fixed for redemption will be paid as specified in said notice, and that on and after said date any interest
              thereon or on the portions thereof to be redeemed will cease to accrue. If less than all the Securities of a series are to be redeemed the notice of redemption shall specify the numbers of the Securities of that series to be redeemed. In case
              any Security of a series is to be redeemed in part only, the notice of redemption shall state the portion of the principal amount thereof to be redeemed and shall state that on and after the date fixed for redemption, upon surrender of such
              Security, a new Security or Securities of that series in principal amount equal to the unredeemed portion thereof will be issued.

             

            On or before the redemption date specified in the notice of redemption given as provided in this Section 1102, the Company will deposit with the Trustee or with one or
              more paying agents an amount of money sufficient to redeem on the redemption date all the Securities or portions thereof so called for redemption at the appropriate redemption price, together with accrued interest to the date fixed for
              redemption.

             

            If less than all the Securities of a series are to be redeemed the Company will give the Trustee notice not less than 60 days prior to the redemption date as to the
              aggregate principal amount of Securities to he redeemed and the Trustee shall select, in such manner as in its sole discretion it shall deem appropriate and fair, the Securities of that series or portions thereof (in multiples of $1,000,
              except as otherwise set forth in the applicable form of Security) to be redeemed.

            SECTION 1103.       Payment of Securities Called for Redemption.  If notice of redemption has been given
              as provided in Section 1102 or Section 1203, the Securities or portions of Securities of the series with respect to which such notice has been given shall become due and payable on the date and at the place or places stated in such notice at
              the applicable redemption price, together with any interest accrued to the date fixed for redemption, and on and after said date (unless the Company shall default in the payment of such Securities at the applicable redemption price, together
              with any interest accrued to said date) any interest on the Securities or portions of Securities of any series so called for redemption shall cease to accrue. On presentation and surrender of such Securities at a place of payment in said
              notice specified, the said Securities or the specified portions thereof shall be paid and redeemed by the Company at the applicable redemption price, together with any interest accrued thereon to the date fixed for redemption.

             

            Upon presentation of any Security redeemed in part only, the Company shall execute and the Trustee shall authenticate and deliver to the Holder thereof, at the expense of
              the Company, a new Security or Securities of such series, of authorized denominations, in principal amount equal to the unredeemed portion of the Security so presented.

              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 Securities of any series is herein referred to as an “optional sinking fund payment”.

             

            SECTION 1202.        Satisfaction of Mandatory Sinking Fund Payments with Securities.  In lien of making
              all or any part of any mandatory sinking fund payment with respect to any Securities of a series in cash, the Company may at its option (a) deliver to the Trustee Securities of that series theretofore purchased or otherwise acquired by the
              Company, or (b) receive credit for the principal amount of Securities of that series which have been previously delivered by the Trustee to the Company which have been redeemed either at the election of the Company pursuant to the terms of
              such Securities or through the application of permitted optional sinking fund payments pursuant to the terms of such Securities; provided that such Securities have not been previously so credited.
              Such Securities shall be received and credited for such purpose by the Trustee at the Redemption Price specified in such Securities for redemption through operation of the sinking fund and the amount of such 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 any series of Securities, the Company will deliver to the Trustee a certificate signed by the Treasurer or any Assistant Treasurer of the Company specifying the amount of the next ensuing sinking fund payment for
              that series pursuant to the terms of that series, the portion thereof, if any, which is to be satisfied by payment of cash and the portion thereof, if any, which is to be satisfied by delivering or crediting Securities of that series pursuant
              to Section 1202 (which Securities will, it not previously delivered, accompany such certificate) and whether the Company intends to exercise its right to make a permitted optional sinking fund payment with respect to such series. Such
              certificate shall also state that no Event of Default has occurred and is continuing with respect to such series. Such certificate shall be irrevocable and upon its delivery the Company shall be obligated to make the cash payment or payments
              therein referred to, if any, on or before the next succeeding sinking fund payment date. In the case of the failure of the Company to deliver such certificate (or to deliver the Securities specified in this paragraph), the sinking fund
              payment due on the next succeeding sinking fund payment date for that series shall be paid entirely in cash and shall be sufficient to redeem the principal amount of such Securities subject to a mandatory sinking fund payment without the
              option to deliver or credit Securities as provided in Section 1202 and without the right to make any optional sinking fund payment, if any, with respect to such series.

             

            Any sinking fund payment or payments (mandatory or optional) made in cash plus any unused balance of any preceding sinking fund payments made, in cash which shall equal or exceed $100,000 (or a lesser sum if the Company shall so request) with respect to the Securities of any particular series shall be applied by the Trustee on
              the sinking fund payment date on which such payment is made (or, if such payment is made before a sinking fund payment date, on the sinking fund payment date following the date of such payment) to the redemption of such Securities at the
              Redemption Price specified in such Securities for operation of the sinking fund together with accrued interest to the date fixed for redemption. Any sinking fund moneys not so applied or allocated by the Trustee to the redemption of
              Securities shall be added to the next cash sinking fund payment received by the Trustee for such series and, together with such payment, shall be applied in accordance with the provisions of this Section 1203. Any and all sinking fund moneys
              with respect to the Securities of any particular series held by the Trustee on the last sinking fund payment date with respect to Securities of such series and not held for the payment or redemption of particular Securities shall be applied
              by the Trustee, together with other moneys, if necessary, to be deposited sufficient for the purpose, to the payment of the principal of the Securities of that series at maturity.

             

            The Trustee shall select the Securities to be redeemed upon such sinking fund payment date in the manner specified in the last paragraph of Section 1102 and the Company
              shall cause notice of the redemption thereof to be given in the manner provided in Section 1102 except that the notice of redemption shall also state that the Securities are being redeemed by operation of the sinking fund. Such notice having
              been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated in Section 1103.

             

            On or before each sinking fund payment date, the Company shall pay to the Trustee in cash a sum equal to any interest accrued to the date fixed for redemption of
              Securities or portions thereof to be redeemed on such sinking fund payment date pursuant to this Section.

             

            

            
              58

              
                


            

            The Trustee shall not redeem any Securities of a series with sinking fund moneys or mail any notice of redemption of such Securities by operation of the sinking fund for
              such series during the continuance of a default in payment of interest on such Securities or of any Event of Default (other than an Event of Default occurring as a consequence of this paragraph) with respect to such Securities, except that if
              the notice of redemption of any such Securities shall theretofore have been mailed in accordance with the provisions hereof, the Trustee shall redeem such Securities if cash sufficient for that purpose shall be deposited with the Trustee for
              that purpose in accordance with the terms of this Article. Except as aforesaid, any moneys in the sinking fund for such series at the time when any such default or Event of Default shall occur and any moneys thereafter paid into such sinking
              fund shall, during the continuance of such default or Event of Default, be held as security for the payment of such Securities; provided, however, that in case such Event of Default or default shall
              have been cured or waived as provided herein, such moneys shall thereafter be applied on the next sinking fund payment date for such Securities on which such moneys may be applied pursuant to the provisions of this Section.

              HOLDERS’ MEETINGS

             

            SECTION 1301.        Purposes of Meetings.

              the following purposes:

             

            (3)  to give any notice to the Company or to the Trustee, or to

            (4)  to remove the Trustee and appoint a successor trustee
                pursuant to the provisions of Article Six;

             

            (5)  to consent to the execution of an indenture or indentures
                supplemental hereto pursuant to the provisions of Section 902; or

             

            (6)  to take any other action authorized to be taken by or on

              SECTION 1302.        Call of Meetings by Trustee.

                  

                

              The Trustee may at any time call a meeting of Holders of Securities of any or all series to take any action specified in Section 1301, to be held at such time and at such place in the Borough of Manhattan, The
                City of New York, as the Trustee shall determine. Notice of every meeting of the Holders of Securities of any or all series, setting forth the time and the place of such meeting and in general terms the action proposed to be taken at such
                meeting, shall be mailed not less than 20 nor more than 60 days prior to the date fixed for the meeting to Holders of Securities of each series affected.

            

             

            SECTION 1303.        Call of Meetings by Company or Holders.

             

            In case at any time the Company, pursuant to a Board Resolution, or the Holders of not less than 10% in aggregate principal amount of the Outstanding Securities of any or
              all series, as the case may be, shall have requested the Trustee to call a meeting of Holders of Securities of all series, if they hold not less than 10% of all Outstanding Securities, or a meeting of Holders of Outstanding Securities of the
              series of which they hold not less than 10%, to take any action authorized in Section 1301, by written request setting forth in reasonable detail the action proposed to be taken at the meeting, and the Trustee shall not have mailed notice of
              such meeting within 20 days after receipt of such request, then the Company or the Holders in the amount above specified may determine the time and the place for such meeting and may call such meeting to take any action authorized in Section
              1301 by mailing notice thereof as provided in Section 1302.

             

            SECTION 1304.        Qualifications for Voting.

             

            To be entitled to vote at any meeting of Holders, a Person shall be a Holder at the close of business two Business Days prior to such meeting of one or more Securities
              with respect to which such meeting is being held or be a Person appointed by an instrument in writing as proxy by such a Holder. The only Persons who will be entitled to be present or to speak at any meeting of Holders shall be the Persons
              entitled to vote at such meeting and their counsel and any representatives of the Trustee and its counsel and any representatives of the Company and its counsel.

             

            SECTION 1305.        Regulations.

             

            Notwithstanding any other provisions of this Indenture, the Trustee may make such reasonable regulations as it may deem advisable for any meeting of Holders, in regard to
              the appointment of proxies, 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 think fit. 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
              said Section 104; provided, however, that such regulations may provide that written instruments appointing proxies, regular on their face, may be presumed valid and genuine without the proof
              hereinbefore or in said Section 104 specified.

             

            

            
              60

              
                


            

            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 the Holders as
              provided in Section 1303, in which case the Company or the Holders calling the meeting, as the case may be, shall in like manner appoint a temporary chairman. A permanent chairman and a permanent secretary of the meeting may be elected by
              vote of the Holders of a majority in principal amount of the Securities with respect to which such meeting is being held represented at the meeting and entitled to vote.

             

            At any meeting each Holder or proxy shall be entitled to one vote for each $1,000 principal amount of Securities with respect to which such meeting is being held or
              represented by him and Outstanding (in the case of Original Issue Discount Securities, such principal amount to be determined as provided in the definition of “Outstanding”); 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 other than by
              virtue of Securities held by him or instruments in writing as aforesaid duly designating him as the Person to vote on behalf of other Holders. Any meeting of Holders duly called pursuant to the provisions of Section 1302 or 1303 may be
              adjourned from time to time by vote of the Holders (or proxies for such Holders) of a majority of the Securities with respect to which such meeting is being held represented at the meeting, and entitled to vote, and the meeting may be held as
              so adjourned without further notice.

             

            Notwithstanding anything in this Section to the contrary, at any meeting of Holders, the presence of Persons holding or representing Securities with respect to which such
              meeting is being held in an aggregate principal amount sufficient under the appropriate provision of this Indenture to take action on any business for the transaction of which such meeting was called shall constitute a quorum, but, if less
              than a quorum is present, the Persons holding or representing a majority in aggregate principal amount of such Securities represented at the meeting may adjourn such meeting with the same effect, for all intents and purposes, as though a
              quorum had been present.

             

            SECTION 1306.        Voting.

             

            The vote upon any resolution submitted to any meeting of Holders of Securities with respect to which such meeting is being held shall be by written ballots on which shall
              be subscribed the signatures of such Holders or proxies and the serial number or numbers and the principal amounts of the Securities held or represented by them. The 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 in duplicate of the
              proceedings of each meeting of Holders 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 facts setting forth a copy of the notice of the meeting and showing that said notice was mailed as provided in Section 1302. The record shall be signed and verified by the affidavits of the chairman and
              secretary of the meeting and one of the duplicates shall be delivered to the Company and the other to the Trustee to be preserved by the Trustee, the latter to have attached thereto the ballots voted at the meeting.

             

            

            
              61

              
                


            

            Any record so signed and verified shall be conclusive evidence of the matters therein stated.

             

            SECTION 1307.        Revocation by Holders.

             

            At any time prior to (but not after) the evidencing to the Trustee, in the manner provided in Section 104, of the taking of any action by the Holders of the percentage in
              aggregate principal amount of the Securities specified in this Indenture in connection with such action, any Person who is the Holder of a Security the serial number of which is included in the Securities, the Holders of which have consented
              to such action may, by filing written notice with the Trustee at the Corporate Trust Office and upon proof of holding as provided in Section 104, revoke such consent so far as concerns such Security, or if such Security is a Predecessor
              Security, so far as concerns the portion of such Security of which such Persons is the Holder. Except as aforesaid any such consent given by the Holder of any Security shall be conclusive and binding upon such Holder and upon all future
              Holders and owners of such Security and of any Security issued in exchange therefor or in lieu thereof, irrespective of whether or not any notation in regard thereto is made upon such Security. Any action taken by the Holders of the
              percentage in aggregate principal amount of the Securities specified in this Indenture in connection with such action shall be conclusively binding upon the Company, the Trustee and the Holders of all the Securities.

             

            SECTION 1308.        No Delay.

             

            Nothing in this Article contained shall be deemed or construed to require any delay in the exercise of any right or rights conferred upon or reserved to the Trustee or to
              the Holders under any of the provisions of this Indenture or of the Securities by reason of any call of a meeting of Holders or any rights expressly or impliedly conferred hereunder to make such call.

             

            SECTION 1309.       Action by Holders.  Whenever in this Indenture it is provided that the Holders of a
              specified percentage in aggregate principal amount of the Securities of any or all series may take any action (including the making of any demand or request, the giving of any notice, consent or waiver or the taking of any other action) the
              fact that at the time of taking any such action the Holders of such specified percentage have joined therein may be evidenced (a) by any instrument or any number of instruments of similar tenor executed by such Holders in person or by agent
              or proxy appointed in writing, or (b) by the record of such Holders voting in favor thereof at any meeting of such Holders duly called and held in accordance with the provisions of this Article Thirteen, or (c) by a combination of such
              instrument or instruments and any such record of such a meeting of such Holders.

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