    The
      aggregate principal amount of Securities that may be authenticated and delivered

      detailing the adoption of the terms thereof pursuant to the authority granted
      under a Board Resolution. In the case of Securities of a Series to be issued
      from time to time, the Board Resolution, Officers’ Certificate or supplemental
      indenture may provide for the method by which specified terms (such as interest
      rate, maturity date, record date or date from which interest shall accrue)
      are
      to be determined. Securities may differ between Series in respect of any
      matters, provided that all Series of Securities shall be equally and ratably
      entitled to the benefits of the Indenture.

    All
      Securities of any one Series need not be issued at the same time and may be
      issued from time to time, consistent with the terms of this Indenture, if so
      provided by or pursuant to the Board Resolution, supplemental indenture or
      Officers’ Certificate referred to above, and the authorized principal amount of
      any Series may not be increased to provide for issuances of additional
      Securities of such Series, unless otherwise provided in such Board Resolution,
      supplemental indenture or Officers’ Certificate. 

    


    Section
      2.3 Execution and Authentication.

     

    Two
      Officers shall sign the Securities for the Company by manual or facsimile
      signature. 

     

    If
      an
      Officer whose signature is on a Security no longer holds that office at the
      time
      the Security is authenticated, the Security shall nevertheless be valid.


     

    A
      Security shall not be valid until authenticated by the manual signature of
      the
      Trustee or an authenticating agent. The signature shall be conclusive evidence
      that the Security has been authenticated under this Indenture. 

     

    The
      Trustee shall at any time, and from time to time, authenticate Securities for
      original issue in the principal amount provided in the Board Resolution,
      supplemental indenture hereto or Officers’ Certificate, upon receipt by the
      Trustee of a Company Order. Such Company Order may authorize authentication
      and
      delivery pursuant to electronic instructions from the Company or its duly
      authorized agent or agents, which instructions shall be promptly confirmed
      in
      writing. Each Security shall be dated the date of its authentication unless
      otherwise provided by a Board Resolution, a supplemental indenture hereto or
      an
      Officers’ Certificate. 

     

    The
      aggregate principal amount of Securities of any Series outstanding at any time
      may not exceed any limit upon the maximum principal amount for such Series
      set
      forth in the Board Resolution, supplemental indenture hereto or Officers’
Certificate delivered pursuant to Section 2.2, except as provided in Section
      2.8. 

     

    Prior
      to
      the issuance of Securities of any Series, the Trustee shall have received and
      (subject to Section 7.2) shall be fully protected in conclusively relying on:
      (a) the Board Resolution, supplemental indenture hereto or Officers’ Certificate
      establishing the form of the Securities of that Series or of Securities within
      that Series and the terms of the Securities of that Series or of Securities
      within that Series, (b) an Officers’ Certificate complying with Section 10.4,
      and (c) an Opinion of Counsel complying with Section 10.4 and stating that
      (i)
      the form and terms of the Securities have been established in conformity with
      the provisions of this Indenture, and (ii) such Securities, when authenticated
      and delivered by the Trustee and issued by the Company in the manner and subject
      to any conditions specified therein, will constitute valid and binding
      obligations of the Company enforceable in accordance with their terms, except
      as
      the enforceability thereof may be limited by bankruptcy, insolvency,
      reorganization, moratorium, or other laws relating to or affecting creditors'
      rights and by general principles of equity.

     

    The
      Trustee shall have the right to decline to authenticate and deliver any
      Securities of such Series: (a) if the Trustee, being advised by counsel,
      determines that such action may not lawfully be taken; or (b) if the Trustee
      in
      good faith by its board of directors or trustees, executive committee or a
      trust
      committee of directors and/or vice-presidents shall determine that such action
      would expose the Trustee to personal liability to Holders of any then
      outstanding Series of Securities.

    The
      Trustee may appoint an authenticating agent acceptable to the Company to
      authenticate Securities. An authenticating agent may authenticate Securities
      whenever the Trustee may do so. Each reference in this Indenture to
      authentication by the Trustee includes authentication by such agent. An
      authenticating agent has the same rights as an Agent to deal with the Company
      or
      an Affiliate. 

    


    Section
      2.4 Registrar and Paying Agent.

     

    The
      Company shall maintain, with respect to each Series of Securities, at the place
      or places specified with respect to such Series pursuant to Section 2.2, an
      office or agency where Securities of such Series may be presented or surrendered
      for payment (“Paying Agent”), where Securities of such Series may be surrendered
      for registration of transfer or exchange (“Registrar”) and where notices and
      demands to or upon the Company in respect of the Securities of such Series
      and
      this Indenture may be served (“Service Agent”). The Registrar shall keep a
      register with respect to each Series of Securities and to their transfer and
      exchange. The Company will give prompt written notice to the Trustee of the
      name
      and address, and any change in the name or address, of each Registrar, Paying
      Agent or Service Agent. If at any time the Company shall fail to maintain any
      such required Registrar, Paying Agent or Service Agent or shall fail to furnish
      the Trustee with the name and address thereof, such presentations, surrenders,
      notices and demands may be made or served at the Corporate Trust Office of
      the
      Trustee, and the Company hereby appoints the Trustee as its agent to receive
      all
      such presentations, surrenders, notices and demands. 

     

    The
      Company may also from time to time designate one or more co-registrars,
      additional paying agents or additional service agents and may from time to
      time
      rescind such designations; provided, however, that no such designation or
      rescission shall in any manner relieve the Company of its obligations to
      maintain a Registrar, Paying Agent and Service Agent in each place so specified
      pursuant to Section 2.2 for Securities of any Series for such purposes. The
      Company will give prompt written notice to the Trustee of any such designation
      or rescission and of any change in the name or address of any such co-registrar,
      additional paying agent or additional service agent. The term “Registrar”
includes any co-registrar; the term “Paying Agent” includes any additional
      paying agent; and the term “Service Agent” includes any additional service
      agent. 

     

    The
      Company hereby appoints the Trustee the initial Registrar, Paying Agent and
      Service Agent for each Series unless another Registrar, Paying Agent or Service
      Agent, as the case may be, is appointed prior to the time Securities of that
      Series are first issued. 

    


    Section
      2.5 Paying Agent to Hold Money in Trust.

     

    The
      Company shall require each Paying Agent other than the Trustee to agree in
      writing that the Paying Agent will hold in trust, for the benefit of
      Securityholders of any Series of Securities, or the Trustee, all money held
      by
      the Paying Agent for the payment of principal of or interest on the Series
      of
      Securities, and will notify the Trustee of any default by the Company in making
      any such payment. While any such default continues, the Trustee may require
      a
      Paying Agent to pay all money held by it to the Trustee. The Company at any
      time
      may require a Paying Agent to pay all money held by it to the Trustee. Upon
      payment over to the Trustee, the Paying Agent (if other than the Company or
      a
      Subsidiary) shall have no further liability for the money. If the Company or
      a
      Subsidiary acts as Paying Agent, it shall segregate and hold in a separate
      trust
      fund for the benefit of Securityholders of any Series of Securities all money
      held by it as Paying Agent. 

    


    Section
      2.6 Securityholder Lists.

     

    The
      Trustee shall preserve in as current a form as is reasonably practicable the
      most recent list available to it of the names and addresses of Securityholders
      of each Series of Securities and shall otherwise comply with TIA Section 312(a).
      If the Trustee is not the Registrar, the Company shall furnish to the Trustee
      at
      least ten days before each interest payment date and at such other times as
      the
      Trustee may request in writing a list, in such form and as of such date as
      the
      Trustee may reasonably require, of the names and addresses of Securityholders
      of
      each Series of Securities.

    Section
      2.7 Transfer and Exchange.

     

    Where
      Securities of a Series are presented to the Registrar or a co-registrar with
      a
      request to register a transfer or to exchange them for an equal principal amount
      of Securities of the same Series, the Registrar shall register the transfer
      or
      make the exchange if its requirements for such transactions are met. To permit
      registrations of transfers and exchanges, the Trustee shall authenticate
      Securities at the Registrar’s request. No service charge shall be made for any
      registration of transfer or exchange (except as otherwise expressly permitted
      herein), but the Company may require payment of a sum sufficient to cover any
      transfer tax or similar governmental charge payable in connection therewith
      (other than any such transfer tax or similar governmental charge payable upon
      exchanges pursuant to Sections 2.11, 3.6 or 9.6). 

     

    Neither
      the Company nor the Registrar shall be required (a) to issue, register the
      transfer of, or exchange Securities of any Series for the period beginning
      at
      the opening of business fifteen days immediately preceding the mailing of a
      notice of redemption of Securities of that Series selected for redemption and
      ending at the close of business on the day of such mailing, or (b) to register
      the transfer of or exchange Securities of any Series selected, called or being
      called for redemption as a whole or the portion being redeemed of any such
      Securities selected, called or being called for redemption in part.


    


    Section
      2.8 Mutilated, Destroyed, Lost and Stolen
      Securities. 

     

    If
      any
      mutilated Security is surrendered to the Trustee, the Company shall execute
      and
      the Trustee shall authenticate and deliver in exchange therefor a new Security
      of the same Series and of like tenor and principal amount and bearing a number
      not contemporaneously outstanding. 

     

    If
      there
      shall be delivered to the Company and the Trustee (i) evidence to their
      satisfaction of the destruction, loss or theft of any Security and (ii) such
      security or indemnity as may be required by them to save each of them and any
      agent of either of them harmless, then, in the absence of notice to the Company
      or the Trustee that such Security has been acquired by a bona fide purchaser,
      the Company shall execute and upon its request the Trustee shall authenticate
      and make available for delivery, in lieu of any such destroyed, lost or stolen
      Security, a new Security of the same Series and of like tenor and principal
      amount and bearing a number not contemporaneously outstanding. 

     

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

     

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

     

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

     

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

    


    Section
      2.9 Outstanding Securities.

     

    The
      Securities outstanding at any time are all the Securities authenticated by
      the
      Trustee except for those canceled by it, those delivered to it for cancellation,
      those reductions in the interest on a Global Security effected by the Trustee
      in
      accordance with the provisions hereof and those described in this Section as
      not
      outstanding. 

     

    If
      a
      Security is replaced pursuant to Section 2.8, it ceases to be outstanding until
      the Trustee receives proof satisfactory to it that the replaced Security is
      held
      by a bona fide purchaser. 

     

    If
      the
      Paying Agent (other than the Company, a Subsidiary or an Affiliate of any
      thereof) holds on the Maturity of Securities of a Series money sufficient to
      pay
      such Securities payable on that date, then on and after that date such
      Securities of the Series cease to be outstanding and interest on them ceases
      to
      accrue. 


    
      
         

      

      
        9

        
          

        

      

      
         

      

    


    A
      Security does not cease to be outstanding because the Company or an Affiliate
      holds the Security. 

     

    In
      determining whether the Holders of the requisite principal amount of outstanding
      Securities have given any request, demand, authorization, direction, notice,
      consent or waiver hereunder, the principal amount of a Discount Security that
      shall be deemed to be outstanding for such purposes shall be the amount of
      the
      principal thereof that would be due and payable as of the date of such
      determination upon a declaration of acceleration of the Maturity thereof
      pursuant to Section 6.2. 

    


    Section
      2.10 Treasury Securities.

     

    In
      determining whether the Holders of the required principal amount of Securities
      of a Series have concurred in any request, demand, authorization, direction,
      notice, consent or waiver Securities of a Series owned by the Company or an
      Affiliate shall be disregarded, except that for the purposes of determining
      whether the Trustee shall be protected in conclusively relying on any such
      request, demand, authorization, direction, notice, consent or waiver only
      Securities of a Series that the Trustee knows are so owned shall be so
      disregarded. 

    


    Section
      2.11 Temporary Securities.

     

    Until
      definitive Securities are ready for delivery, the Company may prepare and the
      Trustee shall authenticate temporary Securities upon a Company Order. Temporary
      Securities shall be substantially in the form of definitive Securities but
      may
      have variations that the Company considers appropriate for temporary Securities.
      Without unreasonable delay, the Company shall prepare and the Trustee upon
      request shall authenticate definitive Securities of the same Series and date
      of
      maturity in exchange for temporary Securities. Until so exchanged, temporary
      securities shall have the same rights under this Indenture as the definitive
      Securities. 

    


    Section
      2.12 Cancellation. 

     

    The
      Company at any time may deliver Securities to the Trustee for cancellation.
      The
      Registrar and the Paying Agent shall forward to the Trustee any Securities
      surrendered to them for registration of transfer, exchange or payment. The
      Trustee shall cancel all Securities surrendered for transfer, exchange, payment,
      replacement or cancellation and shall destroy such canceled Securities (subject
      to the record retention requirement of the Exchange Act) and deliver a
      certificate of such destruction to the Company, unless the Company otherwise
      directs. The Company may not issue new Securities to replace Securities that
      it
      has paid or delivered to the Trustee for cancellation. 

    


    Section
      2.13 Defaulted Interest.

     

    If
      the
      Company defaults in a payment of interest on a Series of Securities, it shall
      pay the defaulted interest, plus, to the extent permitted by law, any interest
      payable on the defaulted interest, to the persons who are Securityholders of
      the
      Series on a subsequent special record date. The Company shall fix the record
      date and payment date. At least 30 days before the record date, the Company
      shall mail to the Trustee and to each Securityholder of the Series a notice
      that
      states the record date, the payment date and the amount of interest to be paid.
      The Company may pay defaulted interest in any other lawful manner. 

     

    Section
      2.14 Global Securities.

     

    2.14.1
      Terms of Securities.
      A Board
      Resolution, a supplemental indenture hereto or an Officers’ Certificate shall
      establish whether the Securities of a Series shall be issued in whole or in
      part
      in the form of one or more Global Securities and the Depositary for such Global
      Security or Securities. 

     

    2.14.2
      Transfer and Exchange.
      Notwithstanding any provisions to the contrary contained in Section 2.7 of
      the
      Indenture and in addition thereto, any Global Security shall be exchangeable
      pursuant to Section 2.7 of the Indenture for Securities registered in the names
      of Holders other than the Depositary for such Security or its nominee only
      if
      (i) such Depositary notifies the Company that it is unwilling or unable to
      continue as Depositary for such Global Security or if at any time such
      Depositary ceases to be a clearing agency registered under the Exchange Act,
      and, in either case, the Company fails to appoint a successor Depositary within
      90 days of such event, (ii) the Company executes and delivers to the Trustee
      an
      Officers’ Certificate to the effect that such Global Security shall be so
      exchangeable or (iii) an Event of Default with respect to the Securities
      represented by such Global Security shall have happened and be continuing.
      Any
      Global Security that is exchangeable pursuant to the preceding sentence shall
      be
      exchangeable for Securities registered in such names as the Depositary shall
      direct in writing in an aggregate principal amount equal to the principal amount
      of the Global Security with like tenor and terms.

    Except
      as
      provided in this Section 2.14.2, a Global Security may not be transferred except
      as a whole by the Depositary with respect to such Global Security to a nominee
      of such Depositary, by a nominee of such Depositary to such Depositary or
      another nominee of such Depositary or by the Depositary or any such nominee
      to a
      successor Depositary or a nominee of such a successor Depositary. 

     

    2.14.3
      Legend.
      Unless
      otherwise provided pursuant to Section 2.2, any Global Security issued hereunder
      shall bear a legend in substantially the following form: 

     

    “This
      Security is a Global Security within the meaning of the Indenture hereinafter
      referred to and is registered in the name of the Depositary or a nominee of
      the
      Depositary. This Security is exchangeable for Securities registered in the
      name
      of a person other than the Depositary or its nominee only in the limited
      circumstances described in the Indenture, and may not be transferred except
      as a
      whole by the Depositary to a nominee of the Depositary, by a nominee of the
      Depositary to the Depositary or another nominee of the Depositary or by the
      Depositary or any such nominee to a successor Depositary or a nominee of such
      a
      successor Depositary.” 

     

    2.14.4
      Acts of Holders.
      The
      Depositary, as a Holder, may appoint agents and otherwise authorize participants
      to give or take any request, demand, authorization, direction, notice, consent,
      waiver or other action which a Holder is entitled to give or take under the
      Indenture. 

     

    2.14.5
      Payments.
      Notwithstanding the other provisions of this Indenture, unless otherwise
      specified as contemplated by Section 2.2, payment of the principal of, premium,
      if any, and interest, if any, on any Global Security shall be made to the Holder
      thereof. 

     

    2.14.6
      Consents, Declaration and Directions.
      With
      respect to a Global Security, the Depositary may be treated by the Company,
      the
      Trustee and any agent of the Company or the Trustee as the absolute owner of
      the
      Global Security for all purposes whatsoever. Notwithstanding the foregoing,
      nothing herein shall prevent the Company, the Trustee or any agent of the
      Company or the Trustee, from giving effect to any written certification, proxy
      or other authorization furnished by the Depositary or impair, as between the
      Depositary and its agent members, the operation of customary practices governing
      the exercise of the rights of a holder of any Note.

    


    2.14.7
      Trustee Protections.
      Each
      Holder of a Security agrees to indemnify the Company and the Trustee against
      any
      liability that may result from the transfer, exchange or assignment of such
      Holder's Security in violation of any provision of this Indenture and/or
      applicable United States Federal or state securities law.

    


    The
      Trustee shall have no obligation or duty to monitor, determine or inquire as
      to
      compliance with any restrictions on transfer imposed under this Indenture or
      under applicable law with respect to any transfer of any interest in any
      Security (including any transfers between or among depositary participants
      or
      beneficial owners of interests in any Global Security) other than to require
      delivery of such certificates and other documentation or evidence as are
      expressly required by, and to do so if and when expressly required by the terms
      of, this Indenture, and to examine the same to determine substantial compliance
      as to form with the express requirements hereof.

    


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

    Section
      2.15 CUSIP Numbers.

     

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

    REDEMPTION
      

    


    Section
      3.1 Notice to Trustee.

     

    The
      Company may, with respect to any Series of Securities, reserve the right to
      redeem and pay the Series of Securities or may covenant to redeem and pay the
      Series of Securities or any part thereof prior to the Stated Maturity thereof
      at
      such time and on such terms as provided for in such Securities. If a Series
      of
      Securities is redeemable and the Company wants or is obligated to redeem prior
      to the Stated Maturity thereof all or part of the Series of Securities pursuant
      to the terms of such Securities, it shall notify the Trustee in writing of
      the
      redemption date and the principal amount of Series of Securities to be redeemed.
      The Company shall give the notice at least 45 days before the redemption date
      (or such shorter notice as may be acceptable to the Trustee). 

    


    Section
      3.2 Selection of Securities to be Redeemed.

     

    Unless
      otherwise indicated for a particular Series by a Board Resolution, a
      supplemental indenture or an Officers’ Certificate, if less than all the
      Securities of a Series are to be redeemed, the Trustee shall select the
      Securities of the Series to be redeemed by lot, pro rata or in any manner that
      the Trustee deems fair and appropriate. The Trustee shall make the selection
      from Securities of the Series outstanding not previously called for redemption.
      The Trustee may select for redemption portions of the principal of Securities
      of
      the Series that have denominations larger than $1,000. Securities of the Series
      and portions of them it selects shall be in amounts of $1,000 or whole multiples
      of $1,000 or, with respect to Securities of any Series issuable in other
      denominations pursuant to Section 2.2.10, the minimum principal denomination
      for
      each Series and integral multiples thereof. Provisions of this Indenture that
      apply to Securities of a Series called for redemption also apply to portions
      of
      Securities of that Series called for redemption. 

    


    Section
      3.3 Notice of Redemption.

     

    Unless
      otherwise indicated for a particular Series by Board Resolution, a supplemental
      indenture hereto or an Officers’ Certificate, at least 30 days but not more than
      90 days before a redemption date, the Company shall mail a notice of redemption
      by first-class mail to each Holder whose Securities are to be redeemed and
      if
      any Bearer Securities are outstanding, publish on one occasion a notice in
      an
      Authorized Newspaper. 

     

    The
      notice shall identify the Securities of the Series to be redeemed (including
      the
      CUSIP numbers thereof) and shall state: 

     

    (a)
      the
      redemption date; 

     

    (b)
      the
      redemption price; 

     

    (c)
      the
      name
      and address of the Paying Agent; 

     

    (d)
      that
      Securities of the Series called for redemption must be surrendered to the Paying
      Agent to collect the redemption price; 


    
      
         

      

      
        12

        
          

        

      

      
         

      

    


    (e)
      that
      interest on Securities of the Series called for redemption ceases to accrue
      on
      and after the redemption date; and 

     

    (f)
      any
      other
      information as may be required by the terms of the particular Series or the
      Securities of a Series being redeemed. 

     

    At
      the
      Company’s request, the Trustee shall give the notice of redemption in the
      Company’s name and at its expense. 

    


    Section
      3.4 Effect of Notice of Redemption. 

     

    Once
      notice of redemption is mailed or published as provided in Section 3.3,
      Securities of a Series called for redemption become due and payable on the
      redemption date and at the redemption price. A notice of redemption may not
      be

      outstanding occurs and is continuing (other than an Event of Default referred
      to
      in Section 6.1(e) or (f)) then in every such case the Trustee or the Holders
      of
      not less than 25% in principal amount of the outstanding Securities of that
      Series may declare the principal amount (or, if any Securities of that Series
      are Discount Securities, such portion of the principal amount as may be

      by Holders), and upon any such declaration such principal amount (or specified
      amount) and accrued and unpaid interest, if any, shall become immediately due
      and payable. If an Event of Default specified in Section 6.1(e) or (f) shall
      occur, the principal amount (or specified amount) of and accrued and unpaid

      of
      a majority in principal amount of the outstanding Securities of that Series,
      by
      written notice to the Company and the Trustee, may rescind and annul such
      declaration and its consequences if: 

     

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

      than
      by such declaration of acceleration and interest thereon at the rate or rates
      prescribed therefor in such Securities, 

     

    (iii)
      to
      the
      extent that payment of such interest is lawful, interest upon any overdue
      principal and overdue interest at the rate or rates prescribed therefor in
      such
      Securities, and 

     

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


     

    (b)
      all
      Events of Default with respect to Securities of that Series, other than the
      non-payment of the principal of Securities of that Series which have become
      due
      solely by such declaration of acceleration, have been cured or waived as
      provided in Section 6.13. 

     

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

    


    Section
      6.3 Collection of Indebtedness and Suits for Enforcement by
      Trustee.

     

    The

    (a)
      default
      is made in the payment of any interest on any Security when such interest
      becomes due and payable and such default continues for a period of 90 days,
      or


     

    (b)
      default
      is made in the payment of principal of any Security at the Maturity thereof,
      or


     

    (c)
      default
      is made in the deposit of any sinking fund payment when and as due by the terms
      of a Security, then, the Company will, upon demand of the Trustee, pay to it,
      for the benefit of the Holders of such Securities, the whole amount then due
      and
      payable on such Securities for principal and interest and, to the extent that
      payment of such interest shall be legally enforceable, interest on any overdue
      principal or any overdue interest, at the rate or rates prescribed therefor
      in
      such Securities, and, in addition thereto, such further amount as shall be
      sufficient to cover the costs and expenses of collection, including the
      reasonable compensation, expenses, disbursements and advances of the Trustee,
      its agents and counsel. 

     

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

     

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

      due and payable as therein expressed or by declaration or otherwise and
      irrespective of whether the Trustee shall have made any demand on the Company
      for the payment of overdue principal or interest) shall be entitled and

      Trustee and, in the event that the Trustee shall consent to the making of such

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

    


    Section
      6.10 Rights and Remedies Cumulative.

     

    Except
      as
      otherwise provided with respect to the replacement or payment of mutilated,
      destroyed, lost or stolen Securities in Section 2.8, no right or remedy herein
      conferred upon or reserved to the Trustee or to the Holders is intended to
      be
      exclusive of any other right or remedy, and every right and remedy shall, to
      the
      extent permitted by law, be cumulative and in addition to every other right
      and
      remedy given hereunder or now or hereafter existing at law or in equity or
      otherwise. The assertion or employment of any right or remedy hereunder, or
      otherwise, shall not prevent the concurrent assertion or employment of any
      other
      appropriate right or remedy.

    Section
      6.11 Delay or Omission Not Waiver.

      

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


    


    Section
      6.12 Control by Holders.

     

    The
      Holders of a majority in principal amount of the outstanding Securities of
      any
      Series shall have the right to direct the time, method and place of conducting
      any proceeding for any remedy available to the Trustee, or exercising any trust
      or power conferred on the Trustee, with respect to the Securities of such
      Series, provided that 

     

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

     

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

     

    (c)
      subject
      to the provisions of Section 6.1, the Trustee shall have the right to decline
      to
      follow any such direction if the Trustee in good faith shall, by a Responsible
      Officer of the Trustee, determine that the proceeding so directed would involve
      the Trustee in personal liability. 

     

    Section
      6.13 Waiver of Past Defaults.

    


    Subject
      to Section 6.2, the Holders of not less than a majority in principal amount
      of
      the outstanding Securities of any Series may on behalf of the Holders of all
      the
      Securities of such Series waive any past Default hereunder with respect to
      such
      Series and its consequences, except a Default in the payment of the principal
      of
      or interest on any Security of such Series (provided, however, that the Holders
      of a majority in principal amount of the outstanding Securities of any Series
      may rescind an acceleration and its consequences, including any related payment
      default that resulted from such acceleration). Upon any such waiver, such
      Default shall cease to exist, and any Event of Default arising therefrom shall
      be deemed to have been cured, for every purpose of this Indenture; but no such
      waiver shall extend to any subsequent or other Default or impair any right
      consequent thereon. 

    


    Section
      6.14 Undertaking for Costs.

     

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

    Section
      7.1 Duties of Trustee.

     

    (a)
      If
      an
      Event of Default has occurred and is continuing, the Trustee shall exercise
      the
      rights and powers vested in it by this Indenture and use the same degree of
      care
      and skill in their exercise as a prudent person would exercise or use under
      the
      circumstances in the conduct of such person’s own affairs. 


    
      
         

      

      
        19

        
          

        

      

      
         

      

    


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

     

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

     

    (ii)
      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 Officers’ Certificates or Opinions of Counsel furnished to the Trustee and
      conforming to the requirements of this Indenture; however, in the case of any
      such Officers’ Certificates or Opinions of Counsel which by any provisions
      hereof are specifically required to be furnished to the Trustee, the Trustee
      shall examine such Officers’ Certificates and Opinions of Counsel to determine
      whether or not they conform to the requirements of this Indenture (but need
      not
      confirm or investigate the accuracy of mathematical calculations or other facts
      stated therein). 

     

    (c)
      The
      Trustee may not be relieved from liability for its own negligent action, its
      own
      negligent failure to act or its own willful misconduct, except that:


     

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


     

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

     

    (iii)
      The
      Trustee shall not be liable with respect to any action taken, suffered or
      omitted to be taken by it with respect to Securities of any Series in good
      faith
      in accordance with the direction of the Holders of a majority in principal
      amount of the outstanding Securities of such Series relating to the time, method
      and place of conducting any proceeding for any remedy available to the Trustee,
      or exercising any trust or power conferred upon the Trustee, under this
      Indenture with respect to the Securities of such Series. 

     

    (d)
      Every
      provision of this Indenture that in any way relates to the Trustee is subject
      to
      paragraph (a), (b) and (c) of this Section. 

     

    (e)
      The
      Trustee may refuse to perform any duty or exercise any right or power unless
      it
      receives indemnity satisfactory to it against any loss, liability, damage,
      claim
      or expense. 

     

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

     

    (g)
      No
      provision of this Indenture shall require the Trustee to risk its own funds
      or
      otherwise incur any financial liability in the performance of any of its duties,
      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 is not reasonably assured to it. 

     

    (h)
      The
      Paying Agent, the Registrar and any authenticating agent shall be entitled
      to
      the protections and immunities as are set forth in paragraphs (a), (b) and
      (c)
      of this Section with respect to the Trustee. 

    


    Section
      7.2 Rights of Trustee.

     

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

     

    (b)
      Before
      the Trustee acts or refrains from acting, it may require an Officers’
Certificate or an Opinion of Counsel. The Trustee shall not be liable for any
      action it takes or omits to take in good faith in reliance on such Officers’
Certificate or Opinion of Counsel. 


    
      
         

      

      
        20

        
          

        

      

      
         

      

    


    (c)
      The
      Trustee may act through agents and shall not be responsible for the misconduct
      or negligence of any agent appointed with due care. No Depositary shall be
      deemed an agent of the Trustee and the Trustee shall not be responsible for
      any
      act or omission by any Depositary. 

     

    (d)
      The
      Trustee shall not be liable for any action it takes or omits to take in good
      faith which it believes to be authorized or within its rights or powers;
provided,
      however,
      that the
      Trustee’s conduct does not constitute willful misconduct, gross negligence or
      bad faith. 

     

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

     

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

    


    (g)
      The
      Trustee shall not be bound to make any investigation into the facts or matters
      stated in any resolution, certificate, statement, instrument, opinion, report,
      notice, request, direction, consent, order, bond, debenture, note, other
      evidence of indebtedness or other paper or document, but the Trustee, in its
      discretion, may make such further inquiry or investigation into such facts
      or
      matters as it may see fit, and, if the Trustee shall determine to make such
      further inquiry or investigation, it shall be entitled to examine the books,
      records and premises of the Company, at reasonable times during normal business
      hours, personally or by agent or attorney at the sole cost of the Company and
      shall incur no liability or additional liability of any kind by reason of such
      inquiry or investigation.

    


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

    


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

    


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

     

    In
      addition, the Trustee shall not be deemed to have knowledge of any Default
      or
      Event of Default until the Trustee shall have received written notification
      in
      the manner set forth in this Indenture or a Responsible Officer of the Trustee
      shall have obtained actual knowledge. Delivery of reports, information and
      documents to the Trustee under Section 4.2 is for informational purposes only
      and the information and the Trustee’s receipt of the foregoing shall not
      constitute constructive notice of any information contained therein, or
      determinable from information contained therein including the Company’s
      compliance with any of their covenants thereunder (as to which the Trustee
      is
      entitled to rely exclusively on an Officers’ Certificate). 

    


    Section
      7.3 Individual Rights of Trustee.

     

    The
      Trustee in its individual or any other capacity may become the owner or pledgee
      of Securities and may otherwise deal with the Company or an Affiliate with
      the
      same rights it would have if it were not Trustee. Any Agent may do the same
      with
      like rights. The Trustee is also subject to Sections 7.10 and 7.11.


    


    Section
      7.4 Trustee’s Disclaimer. 

     

    The
      Trustee makes no representation as to the validity or adequacy of this Indenture
      or the Securities, it shall not be accountable for the Company’s use of the
      proceeds from the Securities, and it shall not be responsible for any statement
      in the Securities other than its authentication. 


    
      
         

      

      
        21

        
          

        

      

      
         

      

    


    Section
      7.5 Notice of Defaults. 

     

    If
      a
      Default or Event of Default occurs and is continuing with respect to the
      Securities of any Series and if it is known to the Trustee, the Trustee shall
      mail to each Securityholder of the Securities of that Series and, if any Bearer
      Securities are outstanding, publish on one occasion in an Authorized Newspaper,
      notice of a Default or Event of Default within 90 days after it occurs or,
      if
      later, after the Trustee has knowledge of such Default or Event of Default.
      Except in the case of a Default or Event of Default in payment of principal
      of
      or interest on any Security of any Series, the Trustee may withhold the notice
      if and so long as its corporate trust committee or a committee of its
      Responsible Officers in good faith determines that withholding the notice is
      in
      the interests of Securityholders of that Series. 

    


    Section
      7.6 Reports by Trustee to Holders.

     

    Within
      60
      days after May 15 in each year, the Trustee shall transmit by mail to all
      Securityholders, as their names and addresses appear on the register kept by
      the
      Registrar and, if any Bearer Securities are outstanding, publish in an
      Authorized Newspaper, a brief report dated as of such May 15, in accordance
      with, and to the extent required under, TIA Section 313. 

     

    A
      copy of
      each report at the time of its mailing to Securityholders of any Series shall
      be
      filed with the SEC and each stock exchange on which the Securities of that
      Series are listed. The Company shall promptly notify the Trustee when Securities
      of any Series are listed on any stock exchange. 

    


    Section
      7.7 Compensation and Indemnity.

     

    The
      Company shall pay to the Trustee from time to time such compensation for its
      services as shall be agreed from time to time in writing. The Trustee’s
      compensation shall not be limited by any law on compensation of a trustee of
      an
      express trust. The Company shall reimburse the Trustee upon request for all
      reasonable disbursements, advances and expenses incurred by it, including the
      reasonable compensation and expenses of the Trustee’s agents and counsel.


     

    The
      Company shall indemnify the Trustee (including the cost of defending itself)
      against any loss, liability, damage, claim or expense incurred by it except
      as
      set forth in the next paragraph in the performance of its duties under this
      Indenture as Trustee or Agent. The Trustee shall notify the Company promptly
      of
      any claim for which it may seek indemnity. The Company shall defend the claim
      and the Trustee shall cooperate in the defense. The Trustee may have separate
      counsel and the Company shall pay the reasonable fees and expenses of such
      counsel. The Company need not pay for any settlement made without its consent,
      which consent shall not be unreasonably withheld. This indemnification shall
      apply to officers, directors, employees, shareholders and agents of the Trustee.
      

     

    The
      Company need not reimburse any expense or indemnify against any loss, liability,
      damage, claim or expense incurred by the Trustee determined by a court of
      competent jurisdiction to have been through negligence or bad faith.


     

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

     

    When
      the
      Trustee incurs expenses or renders services after an Event of Default specified
      in Section 6.1(e) or (f) occurs, the expenses and the compensation for the

      services are intended to constitute expenses of administration under any
      Bankruptcy Law. 

    


    The
      obligations of the Company in this Section 7.7 shall survive the discharge
      of
      the Indenture or resignation of the Trustee.

    Section
      7.8 Replacement of Trustee.

    


    A
      resignation or removal of the Trustee and appointment of a successor Trustee
      shall become effective only upon the successor Trustee’s acceptance of
      appointment as provided in this Section. 

     

    The
      Trustee may resign with respect to the Securities of one or more Series by
      so
      notifying the Company. The Holders of a majority in principal amount of the
      Securities of any Series may remove the Trustee with respect to that Series
      by
      so notifying the Trustee and the Company in writing. The Company may remove
      the
      Trustee with respect to Securities of one or more Series if: 

     

    (a)
      the
      Trustee fails to comply with Section 7.10; 

     

    (b)
      the
      Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered
      with respect to the Trustee under any Bankruptcy Law; 

     

    (c)
      a
      Custodian or public officer takes charge of the Trustee or its property; or
      

     

    (d)
      the
      Trustee becomes incapable of acting. 

     

    If
      the
      Trustee resigns or is removed or if a vacancy exists in the office of Trustee
      for any reason, the Company shall promptly appoint a successor Trustee. Within
      one year after the successor Trustee takes office, the Holders of a majority
      in
      principal amount of the then outstanding Securities may appoint a successor
      Trustee to replace the successor Trustee appointed by the Company. 

     

    If
      a
      successor Trustee with respect to the Securities of any one or more Series
      does
      not take office within 30 days after the retiring Trustee resigns or is removed,
      the retiring Trustee, the Company or the Holders of at least 10% in principal
      amount of the Securities of the applicable Series may petition any court of
      competent jurisdiction for the appointment of a successor Trustee. 

     

    If
      the
      Trustee with respect to the Securities of any one or more Series fails to comply
      with Section 7.10, any Securityholder of the applicable Series may petition
      any
      court of competent jurisdiction for the removal of the Trustee and the
      appointment of a successor Trustee. 

     

    A
      successor Trustee shall deliver a written acceptance of its appointment to
      the
      retiring Trustee and to the Company. Immediately after that, the retiring
      Trustee shall transfer all property held by it as Trustee to the successor
      Trustee subject to the lien provided for in Section 7.7, the resignation or
      removal of the retiring Trustee shall become effective, and the successor
      Trustee shall have all the rights, powers and duties of the Trustee with respect
      to each Series of Securities for which it is acting as Trustee under this
      Indenture. A successor Trustee shall mail a notice of its succession to each
      Securityholder of each such Series and, if any Bearer Securities are
      outstanding, publish such notice on one occasion in an Authorized Newspaper.
      Notwithstanding replacement of the Trustee pursuant to this Section 7.8, the
      Company’s obligations under Section 7.7 hereof shall continue for the benefit of
      the retiring trustee with respect to expenses and liabilities incurred by it
      prior to such replacement. 

    


    Section
      7.9 Successor Trustee by Merger, etc.

     

    If
      the
      Trustee consolidates with, merges or converts into, or transfers all or
      substantially all of its corporate trust business to, another corporation,
      the
      successor corporation without any further act shall be the successor Trustee.
      

    


    Section
      7.10 Eligibility; Disqualification. 

     

    This

      of
      the Company, shall execute proper instruments acknowledging satisfaction and

      all
      Securities theretofore authenticated and delivered (other than Securities that

      been delivered to the Trustee for cancellation; or 

     

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


     

    (1)
      have
      become due and payable, or

      Maturity or redemption date, as the case may be; 

     

    (b)

    Notwithstanding
      the satisfaction and discharge of this Indenture, the obligations of the Company

      principal and interest for whose payment such money has been deposited with
      or
      received by the Trustee or to make mandatory sinking fund payments or analogous
      payments as contemplated by Sections 8.3 or 8.4.

      installment of principal of and interest on the outstanding Securities of such
      Series on the Stated Maturity of such principal or installment of principal
      or
      interest and (ii) the benefit of any mandatory sinking fund payments applicable

      Trustee as trust funds in trust for the purpose of making the following

      benefit of the Holders of such Securities (i) in the case of Securities of
      such
      Series denominated in Dollars, cash in Dollars (or such other money or
      currencies as shall then be legal tender in the United States) and/or U.S.
      Government Obligations, or (ii) in the case of Securities of such Series
      denominated in a Foreign Currency (other than a composite currency), money
      and/or Foreign Government Obligations, which through the payment of interest
      and
      principal in respect thereof, in accordance with their terms, will provide
      (and
      without reinvestment and assuming no tax liability will be imposed on such
      Trustee), not later than one day before the due date of any payment of money,
      an
      amount in cash, sufficient, in the opinion of a nationally recognized firm
      of
      independent public accountants expressed in a written certification thereof
      delivered to the Trustee, to pay and discharge each installment of principal
      (including mandatory sinking fund or analogous payments) of and interest, if
      any, on all the Securities of such Series on the dates such installments of
      interest or principal are due; 

     

    (e)
      such
      deposit will not result in a breach or violation of, or constitute a default
      under, this Indenture or any other agreement or instrument to which the Company
      is a party or by which it is bound; 

     

    (f)
      no
      Default or Event of Default with respect to the Securities of such Series shall
      have occurred and be continuing on the date of such deposit or during the period
      ending on the 91st day after such date;

      Company shall have delivered to the Trustee an Officers’ Certificate and an
      Opinion of Counsel to the effect that (i) the Company has received from, or

      applicable Federal income tax law, in either case to the effect that, and based
      thereon such Opinion of Counsel shall confirm that, the Holders of the
      Securities of such Series will not recognize income, gain or loss for Federal
      income tax purposes as a result of such deposit, defeasance and discharge and
      will be subject to Federal income tax on the same amount and in the same manner
      and at the same times as would have been the case if such deposit, defeasance

      or with the intent of defeating, hindering, delaying or defrauding any other
      creditors of the Company; 

     

    (i)
      such
      deposit shall not result in the trust arising from such deposit constituting
      an
      investment company (as defined in the Investment Company Act of 1940, as
      amended), or such trust shall be qualified under such Act or exempt from
      regulation thereunder; and

    Section
      8.4 Covenant Defeasance.

     

    Unless
      this Section 8.4 is otherwise specified pursuant to Section 2.2.21 to be
      inapplicable to Securities of any Series, on and after the 91st day after the
      date of the deposit referred to in subparagraph (a) hereof, the Company may
      omit
      to comply with any term, provision or condition set forth under Sections 4.2,
      4.3, 4.4, 4.5, 4.6, and 5.1 as well as any additional covenants contained in
      a
      supplemental indenture hereto for a particular Series of Securities or a Board
      Resolution or an Officers’ Certificate delivered pursuant to Section 2.2.21 (and
      the failure to comply with any such covenants shall not constitute a Default
      or
      Event of Default under Section 6.1) and the occurrence of any event described
      in
      clause (e) of Section 6.1 shall not constitute a Default or Event of Default
      hereunder, with respect to the Securities of such Series, provided that the
      following conditions shall have been satisfied: 

     

    (a)
      With

      U.S. Government Obligations, or (ii) in the case of Securities of such Series
      denominated in a Foreign Currency (other than a composite currency), money
      and/or Foreign Government Obligations, which through the payment of interest
      and
      principal in respect thereof, in accordance with their terms, will provide
      (and
      without reinvestment and assuming no tax liability will be imposed on such
      Trustee), not later than one day before the due date of any payment of money,
      an
      amount in cash, sufficient, in the opinion of a nationally recognized firm
      of
      independent certified public accountants expressed in a written certification
      thereof delivered to the Trustee, to pay principal and interest, if any, on
      and
      any mandatory sinking fund in respect of the Securities of such Series on the
      dates such installments of interest or principal are due; 

     

    (b)
      Such
      deposit will not result in a breach or violation of, or constitute a default
      under, this Indenture or any other agreement or instrument to which the Company
      is a party or by which it is bound; 

     

    (c)
      No
      Default or Event of Default with respect to the Securities of such Series shall
      have occurred and be continuing on the date of such deposit or during the period
      ending on the 91st day after such date; 


    
      
         

      

      
        26

        
          

        

      

      
         

      

    


    (d)
      the
      Company shall have delivered to the Trustee an Opinion of Counsel confirming
      that Holders of the Securities of such Series will not recognize income, gain
      or
      loss for federal income tax purposes as a result of such deposit and defeasance
      and will be subject to federal income tax on the same amounts, in the same
      manner and at the same times as would have been the case if such deposit and
      defeasance had not occurred; 

    


    (e)
      the
      Company shall have delivered to the Trustee an Officers’ Certificate stating the
      deposit was not made by the Company with the intent of preferring the Holders
      of
      the Securities of such Series over any other creditors of the Company or with
      the intent of defeating, hindering, delaying or defrauding any other creditors
      of the Company; and 

     

    (f)
      The
      Company shall have delivered to the Trustee an Officers’ Certificate and an
      Opinion of Counsel, each stating that all conditions precedent herein provided
      for relating to the defeasance contemplated by this Section have been complied

    The
      Trustee and the Paying Agent shall pay to the Company upon request any money
      held by them for the payment of principal and interest that remains unclaimed
      for two years or such other shorter period set forth in applicable escheat
      or
      abandoned or unclaimed property law. After that, Securityholders entitled to
      the
      money must look to the Company for payment as general creditors unless an
      applicable abandoned property law designates another person. 

    


    Section
      8.6 Reinstatement.

     

    If
      the
      Trustee or Paying Agent is unable to apply any money or U.S. Government
      Obligations in accordance with Sections 8.1, 8.3 or 8.4, as the case may be,
      by
      reason of any legal proceeding or by reason of any order or judgment of any
      court or governmental authority enjoining, restraining or otherwise prohibiting
      such application, the Company’s obligations under this Indenture and the
      Securities shall be revived and reinstated as though no deposit had occurred
      pursuant to Section 8.1, 8.3 or 8.4, as the case may be, until such time as
      the
      Trustee or Paying Agent is permitted to apply all such money or U.S. Government
      Obligations in accordance with Section 8.1, 8.3 or 8.4, as the case may be;
      provided, however, that if the Company makes any payment of principal of,
      premium, if any, or interest on any Securities because of reinstatement of
      its
      obligations, the Company shall be subrogated to the rights of the holders of
      such Securities to receive such payment from the money or U.S. Government
      Obligations held by the Trustee or Paying Agent.

    (a)
      to
      cure
      any ambiguity, defect or inconsistency; 

     

    (b)
      to

    (f)
      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

    Section
      9.2 With Consent of Holders.

     

    The
      Company and the Trustee may enter into a supplemental indenture with the written
      consent of the Holders of at least a majority in principal amount of the
      outstanding Securities of each Series affected by such supplemental indenture
      (including consents obtained in connection with a tender offer or exchange
      offer
      for the Securities of such Series), for the purpose of adding any provisions
      to
      or changing in any manner or eliminating any of the provisions of this Indenture
      or of any supplemental indenture or of modifying in any manner the rights of
      the
      Securityholders of each such Series. Except as provided in Section 6.13, the
      Holders of at least a majority in principal amount of the outstanding Securities
      of each Series affected by such waiver by notice to the Trustee (including
      consents obtained in connection with a tender offer or exchange offer for the
      Securities of such Series) may waive compliance by the Company with any
      provision of this Indenture or the Securities with respect to such Series.
      

     

    It
      shall
      not be necessary for the consent of the Holders of Securities under this Section
      9.2 to approve the particular form of any proposed supplemental indenture or
      waiver, but it shall be sufficient if such consent approves the substance
      thereof. After a supplemental indenture or waiver under this Section becomes
      effective, the Company shall mail to the Holders of Securities affected thereby
      and, if any Bearer Securities affected thereby are outstanding, publish on
      one
      occasion in an Authorized Newspaper, a notice briefly describing the
      supplemental indenture or waiver. Any failure by the Company to mail or publish
      such notice, or any defect therein, shall not, however, in any way impair or
      affect the validity of any such supplemental indenture or waiver. 

    


    Section
      9.3 Limitations.

     

    Without
      the consent of each Securityholder affected, an amendment or waiver may not:
      

     

    (a)
      change
      the amount of Securities whose Holders must consent to an amendment, supplement
      or waiver; 

     

    (b)
      reduce
      the rate of or extend the time for payment of interest (including default
      interest) on any Security; 

     

    (c)
      reduce
      the principal or change the Stated Maturity of any Security or reduce the amount
      of, or postpone the date fixed for, the payment of any sinking fund or analogous
      obligation; 

     

    (d)
      reduce
      the principal amount of Discount Securities payable upon acceleration of the

      if
      any, on any Security (except a rescission of acceleration of the Securities
      of
      any Series by the Holders of at least a majority in principal amount of the
      outstanding Securities of such Series and a waiver of the payment default that
      resulted from such acceleration); 

     

    (f)
      make
      the
      principal of or interest, if any, on any Security payable in any currency other
      than that stated in the Security; 

     

    (g)
      make
      any
      change in Sections 6.8, 6.13, 9.3, 10.15 or 10.16; or

      forth in a supplemental indenture hereto that complies with the TIA as then
      in
      effect. 

    


    Section
      9.5 Revocation and Effect of Consents.

     

    Until
      an
      amendment or waiver becomes effective, a consent to it by a Holder of a Security
      is a continuing consent by the Holder and every subsequent Holder of a Security
      or portion of a Security that evidences the same debt as the consenting Holder’s
      Security, even if notation of the consent is not made on any Security. However,
      any such Holder or subsequent Holder may revoke the consent as to his Security
      or portion of a Security if the Trustee receives the notice of revocation before
      the date the amendment or waiver becomes effective. 

     

    Any
      amendment or waiver once effective shall bind every Securityholder of each
      Series affected by such amendment or waiver unless it is of the type described
      in any of clauses (a) through (g) of Section 9.3. In that case, the amendment
      or
      waiver shall bind each Holder of a Security who has consented to it and every
      subsequent Holder of a Security or portion of a Security that evidences the
      same
      debt as the consenting Holder’s Security. 

    


    Section
      9.6 Notation on or Exchange of Securities.

     

    The
      Trustee may place an appropriate notation about an amendment or waiver on any
      Security of any Series thereafter authenticated. The Company in exchange for
      Securities of that Series may issue and the Trustee shall authenticate upon
      request new Securities of that Series that reflect the amendment or waiver.
      

    


    Section
      9.7 Trustee Protected.

     

    In
      executing, or accepting the additional trusts created by, any supplemental
      indenture permitted by this Article or the modifications thereby of the trusts
      created by this Indenture, the Trustee shall be entitled to receive, and
      (subject to Section 7.1) shall be fully protected in conclusively relying upon,
      an Officers’ Certificate and an Opinion of Counsel stating that the execution of
      such supplemental indenture is authorized or permitted by this Indenture. The
      Trustee shall sign all supplemental indentures, except that the Trustee need
      not
      sign any supplemental indenture that adversely affects its rights.

      or
      the Indenture or for any claim based on, in respect of or by reason of such

    Section
      10.15 Securities in a Foreign Currency or in ECU.

     

    Unless
      otherwise specified in a Board Resolution, a supplemental indenture hereto
      or an
      Officers’ Certificate delivered pursuant to Section 2.2 of this Indenture with
      respect to a particular Series of Securities, whenever for purposes of this
      Indenture any action may be taken by the Holders of a specified percentage
      in
      aggregate principal amount of Securities of all Series or all Series affected
      by
      a particular action at the time outstanding and, at such time, there are
      outstanding Securities of any Series which are denominated in a coin or currency
      other than Dollars (including ECUs), then the principal amount of Securities
      of
      such Series which shall be deemed to be outstanding for the purpose of taking
      such action shall be that amount of Dollars that could be obtained for such
      amount at the Market Exchange Rate at such time. For purposes of this Section
      10.15, “Market Exchange Rate” shall mean the noon Dollar buying rate in New York
      City for cable transfers of that currency as published by the Federal Reserve
      Bank of New York; provided, however, in the case of ECUs, Market Exchange Rate
      shall mean the rate of exchange determined by the Commission of the European
      Union (or any successor thereto) as published in the Official Journal of the
      European Union (such publication or any successor publication, the “Journal”).
      If such Market Exchange Rate is not available for any reason with respect to
      such currency, the Trustee shall use, in its sole discretion and without
      liability on its part, such quotation of the Federal Reserve Bank of New York
      or, in the case of ECUs, the rate of exchange as published in the Journal,
      as of
      the most recent available date, or quotations or, in the case of ECUs, rates
      of
      exchange from one or more major banks in The City of New York or in the country
      of issue of the currency in question or, in the case of ECUs, in Luxembourg
      or
      such other quotations or, in the case of ECUs, rates of exchange as the Trustee,
      upon consultation with the Company, shall deem appropriate. The provisions
      of
      this paragraph shall apply in determining the equivalent principal amount in
      respect of Securities of a Series denominated in currency other than Dollars
      in
      connection with any action taken by Holders of Securities pursuant to the terms
      of this Indenture. 

     

    All
      decisions and determinations of the Trustee regarding the Market Exchange Rate
      or any alternative determination provided for in the preceding paragraph shall
      be in its sole discretion and shall, in the absence of manifest error, be
      conclusive to the extent permitted by law for all purposes and irrevocably
      binding upon the Company and all Holders. 

     

    Section
      10.16 Judgment Currency.

    


    The
      Company agrees, to the fullest extent that it may effectively do so under
      applicable law, that (a) if for the purpose of obtaining judgment in any court
      it is necessary to convert the sum due in respect of the principal of or
      interest or other amount on the Securities of any Series (the “Required
      Currency”) into a currency in which a judgment will be rendered (the “Judgment
      Currency”), the rate of exchange used shall be the rate at which in accordance
      with normal banking procedures the Trustee could purchase in The City of New
      York the Required Currency with the Judgment Currency on the day on which final
      unappealable judgment is entered, unless such day is not a New York Banking
      Day,
      then, the rate of exchange used shall be the rate at which in accordance with
      normal banking procedures the Trustee could purchase in The City of New York
      the
      Required Currency with the Judgment Currency on the New York Banking Day
      preceding the day on which final unappealable judgment is entered and (b) its
      obligations under this Indenture to make payments in the Required Currency
      (i)
      shall not be discharged or satisfied by any tender, any recovery pursuant to
      any
      judgment (whether or not entered in accordance with clause (a) ), in any
      currency other than the Required Currency, except to the extent that such tender
      or recovery shall result in the actual receipt, by the payee, of the full amount
      of the Required Currency expressed to be payable in respect of such payments,
      (ii) shall be enforceable as an alternative or additional cause of action for
      the purpose of recovering in the Required Currency the amount, if any, by which
      such actual receipt shall fall short of the full amount of the Required Currency
      so expressed to be payable, and (iii) shall not be affected by judgment being
      obtained for any other sum due under this Indenture. For purposes of the
      foregoing, “New York Banking Day” means any day except a Saturday, Sunday or a
      legal holiday in The City of New York on which banking institutions are
      authorized or required by law, regulation or executive order to close.


    


    Section
      10.17 Force Majeure.

    


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

    ARTICLE
      XI 

     

    SINKING
      FUNDS 

    


    Section
      11.1 Applicability of Article.

     

    The
      provisions of this Article shall be applicable to any sinking fund for the
      retirement of the Securities of a Series, except as otherwise permitted or
      required by any form of Security of such Series issued pursuant to this
      Indenture. 

     

    The
      minimum amount of any sinking fund payment provided for by the terms of the
      Securities of any Series is herein referred to as a “mandatory sinking fund
      payment” and any other amount provided for by the terms of Securities of such
      Series is herein referred to as an “optional sinking fund payment.” If provided
      for by the terms of Securities of any Series, the cash amount of any sinking
      fund payment may be subject to reduction as provided in Section 11.2. Each
      sinking fund payment shall be applied to the redemption of Securities of any
      Series as provided for by the terms of the Securities of such Series.


    


    Section
      11.2 Satisfaction of Sinking Fund Payments with
      Securities.

     

    The
      Company may, in satisfaction of all or any part of any sinking fund payment
      with
      respect to the Securities of any Series to be made pursuant to the terms of
      such
      Securities 

     

    (1)
      deliver outstanding Securities of such Series to which such sinking fund payment
      is applicable (other than any of such Securities previously called for mandatory
      sinking fund redemption) and (2) apply as credit Securities of such Series
      to
      which such sinking fund payment is applicable and which have been redeemed
      either at the election of the Company pursuant to the terms of such Series
      of
      Securities (except pursuant to any mandatory sinking fund) or through the
      application of permitted optional sinking fund payments or other optional
      redemptions pursuant to the terms of such Securities, provided that such
      Securities have not been previously so credited. Such Securities shall be
      received by the Trustee, together with an Officers’ Certificate with respect
      thereto, not later than 15 days prior to the date on which the Trustee begins
      the process of selecting Securities for redemption, and shall be credited for
      such purpose by the Trustee at the price specified in such Securities for
      redemption through operation of the sinking fund and the amount of such sinking
      fund payment shall be reduced accordingly. If as a result of the delivery or
      credit of Securities in lieu of cash payments pursuant to this Section 11.2,
      the
      principal amount of Securities of such Series to be redeemed in order to exhaust
      the aforesaid cash payment shall be less than $100,000, the Trustee need not
      call Securities of such Series for redemption, except upon receipt of a Company
      Order that such action be taken, and such cash payment shall be held by the
      Trustee or a Paying Agent and applied to the next succeeding sinking fund
      payment, provided, however, that the Trustee or such Paying Agent shall from
      time to time upon receipt of a Company Order pay over and deliver to the Company
      any cash payment so being held by the Trustee or such Paying Agent upon delivery
      by the Company to the Trustee of Securities of that Series purchased by the
      Company having an unpaid principal amount equal to the cash payment required
      to
      be released to the Company. 

    


    Section
      11.3 Redemption of Securities for Sinking Fund.

     

    Not
      less
      than 45 days (unless otherwise indicated in the Board Resolution, supplemental
      indenture hereto or Officers’ Certificate in respect of a particular Series of
      Securities) prior to each sinking fund payment date for any Series of
      Securities, the Company will deliver to the Trustee an Officers’ Certificate
      specifying the amount of the next ensuing mandatory sinking fund payment for
      that Series pursuant to the terms of that Series, the portion thereof, if any,
      which is to be satisfied by payment of cash and the portion thereof, if any,
      which is to be satisfied by delivering and crediting of Securities of that
      Series pursuant to Section 11.2, and the optional amount, if any, to be added
      in
      cash to the next ensuing mandatory sinking fund payment, and the Company shall
      thereupon be obligated to pay the amount therein specified. Not less than 30
      days (unless otherwise indicated in the Board Resolution, Officers’ Certificate
      or supplemental indenture in respect of a particular Series of Securities)
      before each such sinking fund payment date the Trustee shall select the
      Securities to be redeemed upon such sinking fund payment date in the manner
      specified in Section 3.2 and cause notice of the redemption thereof to be given
      in the name of and at the expense of the Company in the manner provided in
      Section 3.3. Such notice having been duly given, the redemption of such
      Securities shall be made upon the terms and in the manner stated in Sections
      3.4, 3.5 and 3.6.
