  ARTICLE 2

  THE SECURITIES

      Section 2.01.
      Form and Dating. The Securities
      of each series shall be substantially in such form or forms (not inconsistent
      with this Indenture) as shall be established by or pursuant to one or more
      Board Resolutions or in one or more indentures supplemental hereto, in
      each case with such appropriate insertions, omissions, substitutions and
      other variations as are required or permitted by this Indenture and may
      have imprinted or otherwise reproduced thereon such legend or legends or
      endorsements, not inconsistent with the provisions of this Indenture, as
      may be required to comply with any law, or with any rules of any securities
      exchange or usage, all as may be determined by the officers executing such
      Securities as evidenced by their execution of the Securities. Unless otherwise
      so established, Unregistered Securities shall have coupons attached. 

      Section 2.02.
      Execution And Authentication. Two
      Officers shall execute the Securities and one Officer shall execute the
      coupons appertaining thereto for the Company by facsimile or manual signature
      in the name and on behalf of the Company. The seal of the Company, if any,
      shall be reproduced on the Securities. If an Officer whose signature is
      on a Security or coupon appertaining thereto no longer holds that office
      at the time the Security is authenticated, the Security and such coupon
      shall nevertheless be valid.

      The Trustee, at
    the expense of the Company, may appoint an authenticating agent (the “Authenticating
    Agent”) to authenticate Securities.
    The 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 Authenticating Agent. 

      A Security and
    the coupons appertaining thereto shall not be valid until the Trustee or
    Authenticating Agent manually signs the certificate of authentication on
    the Security or on the Security to which such coupon appertains by an authorized
    officer. The signature shall be conclusive evidence that the Security or
    the Security to which the coupon appertains has been authenticated under
    this Indenture. 

      At any time and
    from time to time after the execution and delivery of this Indenture, the
    Company may deliver Securities of any series having attached thereto appropriate
    coupons, if any, executed by the Company to the Trustee for authentication
    together with the applicable documents referred to below in this Section,
    and the Trustee shall thereupon authenticate and deliver such Securities
    to or upon the written order of the Company. In authenticating any Securities
    of a series, the Trustee shall be entitled to receive prior to the authentication
    of any 

 9

 Securities of such series, and (subject to Article
    7) shall be fully protected in relying upon, unless and until such documents
    have been superseded or revoked:

        (a) any
      Board Resolution and/or executed supplemental indenture referred to in
      Sections 2.01 and 2.03 by or pursuant to which the forms and terms of the
      Securities of that series were established; 

        (b) an
      Officers’ Certificate setting forth the form or forms and terms of
      the Securities, stating that the form or forms and terms of the Securities
      of such series have been, or, in the case of a Periodic Offering, will
      be when established in accordance with such procedures as shall be referred
      to therein, established in compliance with this Indenture; and

        (c) an
      Opinion of Counsel substantially to the effect that the form or forms and
      terms of the Securities of such series have been, or, in the case of a
      Periodic Offering, will be when established in accordance with such procedures
      as shall be referred to therein, established in compliance with this Indenture
      and that the supplemental indenture, to the extent applicable, and Securities
      have been duly authorized and, if executed and authenticated in accordance
      with the provisions of the Indenture and delivered to and duly paid for
      by the purchasers thereof on the date of such opinion, would be entitled
      to the benefits of the Indenture and would be valid and binding obligations
      of the Company, enforceable against the Company in accordance with their
      respective terms, subject to bankruptcy, insolvency, reorganization, receivership,
      moratorium and other similar laws affecting creditors’ rights generally,
      general principles of equity, and covering such other matters as shall
      be specified therein and as shall be reasonably requested by the Trustee. 

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

      Notwithstanding
    the provisions of Sections 2.01 and 2.02, if, in connection with a Periodic
    Offering, all Securities of a series are not to be originally issued at one
    time, it shall not be necessary to deliver the Board Resolution otherwise
    required pursuant to Section 2.01 or the written order, Officers’ Certificate
    and Opinion of Counsel otherwise required pursuant to Section 2.02 at or
    prior to the authentication of each Security of such series if such documents
    are delivered at or prior to the authentication upon original issuance of
    the first Security of such series to be issued. 

      With respect to
    Securities of a series offered in a Periodic Offering, the Trustee may rely,
    as to the authorization by the Company of any of such 

 10

 Securities, the forms and terms thereof and the
    legality, validity, binding effect and enforceability thereof, upon the Opinion
    of Counsel and the other documents delivered pursuant to Sections 2.01 and
    2.02, as applicable, in connection with the first authentication of Securities
    of such series. 

      If the Company
    shall establish pursuant to Section 2.03 that the Securities of a series
    or a portion thereof are to be issued in the form of one or more Registered
    Global Securities, then the Company shall execute and the Trustee shall authenticate
    and deliver one or more Registered Global Securities that (i) shall represent
    and shall be denominated in an amount equal to the aggregate principal amount
    of all of the Securities of such series issued in such form and not yet cancelled,
    (ii) shall be registered in the name of the Depositary for such Registered
    Global Security or Securities or the nominee of such Depositary, (iii) shall
    be delivered by the Trustee to such Depositary or its custodian or pursuant
    to such Depositary’s instructions and (iv) shall bear a legend substantially
    to the following effect: “Unless and until it is exchanged in whole
    or in part for Securities in definitive registered form, this Security may
    not be transferred except as a whole by the Depositary to the nominee of
    the Depositary or 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 successor Depositary.”

      Section 2.03.
      Amount Unlimited; Issuable in Series. The
      aggregate principal amount of Securities which may be authenticated and
      delivered under this Indenture is unlimited. 

      The Securities
    may be issued in one or more series. There shall be established in or pursuant
    to Board Resolution or one or more indentures supplemental hereto, prior
    to the initial issuance of Securities of any series, subject to the last
    sentence of this Section 2.03,

      (a) the
    designation of the Securities of the series, which shall distinguish the
    Securities of the series from the Securities of all other series; 

      (b) any
    limit upon the aggregate principal amount of the Securities of the series
    that may be authenticated and delivered under this Indenture and any limitation
    on the ability of the Company to increase such aggregate principal amount
    after the initial issuance of the Securities of that series (except for Securities
    authenticated and delivered upon registration of transfer of, or in exchange
    for, or in lieu of, or upon redemption of, other Securities of the series
    pursuant hereto); 

      (c) the
    date or dates on which the principal of the Securities of the series is payable
    (which date or dates may be fixed or extendible); 

 11

      (d) the
    rate or rates (which may be fixed or variable) per annum at which the Securities
    of the series shall bear interest, if any, the date or dates from which such
    interest shall accrue, on which such interest shall be payable and (in the
    case of Registered Securities) on which a record shall be taken for the determination
    of Holders to whom interest is payable and/or the method by which such rate
    or rates or date or dates shall be determined; 

      (e) if
    other than as provided in Section 4.02, the place or places where the principal
    of and any interest on Securities of the series shall be payable, any Registered
    Securities of the series may be surrendered for exchange, notices, demands
    to or upon the Company in respect of the Securities of the series and this
    Indenture may be served and notice to Holders may be published; 

      (f) the
    right, if any, of the Company to redeem Securities of the series, in whole
    or in part, at its option and the period or periods within which, the price
    or prices at which and any terms and conditions upon which Securities of
    the series may be so redeemed, pursuant to any sinking fund or otherwise; 

      (g) the
    obligation, if any, of the Company to redeem, purchase or repay Securities
    of the series pursuant to any mandatory redemption, sinking fund or analogous
    provisions or at the option of a Holder thereof and the price or prices at
    which and the period or periods within which and any of the terms and conditions
    upon which Securities of the series shall be redeemed, purchased or repaid,
    in whole or in part, pursuant to such obligation; 

      (h) if
    other than denominations of $1,000 and any integral multiple thereof, the
    denominations in which Securities of the series shall be issuable; 

      (i) if
    other than the principal amount thereof, the portion of the principal amount
    of Securities of the series which shall be payable upon declaration of acceleration
    of the maturity thereof; 

      (j) if
    other than the coin or currency in which the Securities of the series are
    denominated, the coin or currency in which payment of the principal of or
    interest on the Securities of the series shall be payable or if the amount
    of payments of principal of and/or interest on the Securities of the series
    may be determined with reference to an index based on a coin or currency
    other than that in which the Securities of the series are denominated, the
    manner in which such amounts shall be determined; 

      (k) if
    other than the currency of the United States of America, the currency or
    currencies, including composite currencies, in which payment of the Principal
    of and interest on the Securities of the series shall be payable, and the
    manner in which any such currencies shall be valued against other currencies
    in which any other Securities shall be payable; 

 12

      (l) whether
    the Securities of the series or any portion thereof will be issuable as Registered
    Securities (and if so, whether such Securities will be issuable as Registered
    Global Securities) or Unregistered Securities (with or without coupons) (and
    if so, whether such Securities will be issued in temporary or permanent global
    form), or any combination of the foregoing, any restrictions applicable to
    the offer, sale or delivery of Unregistered Securities or the payment of
    interest thereon and, if other than as provided herein, the terms upon which
    Unregistered Securities of any series may be exchanged for Registered Securities
    of such series and vice versa;

      (m) whether
    and under what circumstances the Company will pay additional amounts on the
    Securities of the series held by a person who is not a U.S. person in respect
    of any tax, assessment or governmental charge withheld or deducted and, if
    so, whether the Company will have the option to redeem such Securities rather
    than pay such additional amounts;

      (n) if
    the Securities of the series are to be issuable in definitive form (whether
    upon original issue or upon exchange of a temporary Security of such series)
    only upon receipt of certain certificates or other documents or satisfaction
    of other conditions, the form and terms of such certificates, documents or
    conditions;

      (o) any
    trustees, depositaries, authenticating or paying agents, transfer agents
    or the registrar or any other agents with respect to the Securities of the
    series;

      (p) provisions,
    if any, for the defeasance of the Securities of the series (including provisions
    permitting defeasance of less than all Securities of the series), which provisions
    may be in addition to, in substitution for, or in modification of (or any
    combination of the foregoing) the provisions of Article 8;

      (q) if
    the Securities of the series are issuable in whole or in part as one or more
    Registered Global Securities or Unregistered Securities in global form, the
    identity of the Depositary or common Depositary for such Registered Global
    Security or Securities or Unregistered Securities in global form; 

      (r) any
    other Events of Default or covenants with respect to the Securities of the
    series; and

      (s) any
    other terms of the Securities of the series (which terms shall not be inconsistent
    with the provisions of this Indenture).

      All Securities
    of any one series and coupons, if any, appertaining thereto shall be substantially
    identical, except in the case of Registered Securities as to date and denomination,
    except in the case of any Periodic Offering and except as 

 13

 may otherwise be provided by or pursuant to the
    Board Resolution referred to above or as set forth in any such indenture
    supplemental hereto. 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 such Board Resolution
    or in any such indenture supplemental hereto and any forms and terms of Securities
    to be issued from time to time may be completed and established from time
    to time prior to the issuance thereof by procedures described in such Board
    Resolution or supplemental indenture. 

      Unless otherwise
    expressly provided with respect to a series of Securities, the aggregate
    principal amount of a series of Securities may be increased and additional
    Securities of such series may be issued up to the maximum aggregate principal
    amount authorized with respect to such series as increased. 

 Section 2.04.
      Denomination and Date of Securities; Payments of Interest.

 The Securities of each series shall be issuable
    as Registered Securities or Unregistered Securities in denominations established
    as contemplated by Section 2.03 or, if not so established with respect to
    Securities of any series, in denominations of $1,000 and any integral multiple
    thereof. The Securities of each series shall be numbered, lettered or otherwise
    distinguished in such manner or in accordance with such plan as the Officers
    of the Company executing the same may determine, as evidenced by their execution
    thereof. 

      Unless otherwise
    specified with respect to a series of Securities, each Security shall be
    dated the date of its authentication. The Securities of each series shall
    bear interest, if any, from the date, and such interest and shall be payable
    on the dates, established as contemplated by Section 2.03. 

      The person in whose
    name any Registered Security of any series is registered at the close of
    business on any record date applicable to a particular series with respect
    to any interest payment date for such series shall be entitled to receive
    the interest, if any, payable on such interest payment date notwithstanding
    any transfer or exchange of such Registered Security subsequent to the record
    date and prior to such interest payment date, except if and to the extent
    the Company shall default in the payment of the interest due on such interest
    payment date for such series, in which case the provisions of Section 2.13
    shall apply. The term “record
    date” as used with respect to
    any interest payment date (except a date for payment of defaulted interest)
    for the Securities of any series shall mean the date specified as such in
    the terms of the Registered Securities of such series established as contemplated
    by Section 2.03, or, if no such date is so established, the fifteenth day
    next preceding such interest payment date, whether or not such record date
    is a Business Day. 

 14

      Section 2.05.
      Registrar and Paying Agent; Agents Generally. The
      Company shall maintain an office or agency where Securities may be presented
      for registration, registration of transfer or for exchange (the “Registrar”)
      and an office or agency where Securities may be presented for payment (the
  “Paying Agent”),
  which shall be in the Borough of Manhattan, The City of New York or in Chicago,
  Illinois. The Company shall cause the Registrar to keep a register of the Registered
  Securities and of their registration, transfer and exchange (the “Security
  Register”). The Company may have
  one or more additional Paying Agents or transfer agents with respect to any
  series. 

      The Company shall
    enter into an appropriate agency agreement with any Agent not a party to
    this Indenture. The agreement shall implement the provisions of this Indenture
    and the Trust Indenture Act that relate to such Agent. The Company shall
    give prompt written notice to the Trustee of the name and address of any
    Agent and any change in the name or address of an Agent. If the Company fails
    to maintain a Registrar or Paying Agent, the Trustee shall act as such. The
    Company may remove any Agent upon written notice to such Agent and the Trustee; provided that
    no such removal shall become effective until (i) the acceptance of an appointment
    by a successor Agent to such Agent as evidenced by an appropriate agency
    agreement entered into by the Company and such successor Agent and delivered
    to the Trustee or (ii) notification to the Trustee that the Trustee shall
    serve as such Agent until the appointment of a successor Agent in accordance
    with clause (i) of this proviso. The Company or any affiliate of the Company
    may act as Paying Agent or Registrar; provided that
    neither the Company nor an affiliate of the Company shall act as Paying Agent
    in connection with the defeasance of the Securities or the discharge of this
    Indenture under Article 8. 

      The Company initially
    appoints the Trustee as Registrar, Paying Agent and Authenticating Agent.
    If, at any time, the Trustee is not the Registrar, the Registrar shall make
    available to the Trustee ten days prior to each interest payment date and
    at such other times as the Trustee may reasonably request the names and addresses
    of the Holders as they appear in the Security Register. 

      Section 2.06.
      Paying Agent to Hold Money in Trust. Not
      later than 10:00 a.m. New York City time on each due date or, in the case
      of Unregistered Securities, 10:00 a.m. New York City time on the Business
      Day prior to the due date, of any Principal or interest on any Securities,
      the Company shall deposit with the Paying Agent money in immediately available
      funds sufficient to pay such Principal or interest. The Company shall require
      each Paying Agent other than the Trustee to agree in writing that such
      Paying Agent shall hold in trust for the benefit of the Holders of such
      Securities or the Trustee all money held by the Paying Agent for the payment
      of Principal of and interest on such Securities and shall promptly notify
      the Trustee of any default by the Company in making any 

 15

 such payment. The Company at any time may require
    a Paying Agent to pay all money held by it to the Trustee and account for
    any funds disbursed, and the Trustee may at any time during the continuance
    of any payment default, upon written request to a Paying Agent, require such
    Paying Agent to pay all money held by it to the Trustee and to account for
    any funds disbursed. Upon doing so, the Paying Agent shall have no further
    liability for the money so paid over to the Trustee. If the Company or any
    affiliate of the Company acts as Paying Agent, it will, on or before each
    due date of any Principal of or interest on any Securities, segregate and
    hold in a separate trust fund for the benefit of the Holders thereof a sum
    of money sufficient to pay such Principal or interest so becoming due until
    such sum of money shall be paid to such Holders or otherwise disposed of
    as provided in this Indenture, and will promptly notify the Trustee in writing
    of its action or failure to act as required by this Section. 

      Section 2.07.
      Transfer and Exchange. Unregistered
      Securities (except for any temporary global Unregistered Securities) and
      coupons (except for coupons attached to any temporary global Unregistered
      Securities) shall be transferable by delivery.

      At the option of
    the Holder thereof, Registered Securities of any series (other than a Registered
    Global Security, except as set forth below) may be exchanged for a Registered
    Security or Registered Securities of such series and tenor having authorized
    denominations and an equal aggregate principal amount, upon surrender of
    such Registered Securities to be exchanged at the agency of the Company that
    shall be maintained for such purpose in accordance with Section 2.05 and
    upon payment, if the Company shall so require, of the charges hereinafter
    provided. If the Securities of any series are issued in both registered and
    unregistered form, except as otherwise established pursuant to Section 2.03,
    at the option of the Holder thereof, Unregistered Securities of any series
    may be exchanged for Registered Securities of such series and tenor having
    authorized denominations and an equal aggregate principal amount, upon surrender
    of such Unregistered Securities to be exchanged at the agency of the Company
    that shall be maintained for such purpose in accordance with Section 4.02,
    with, in the case of Unregistered Securities that have coupons attached,
    all unmatured coupons and all matured coupons in default thereto appertaining,
    and upon payment, if the Company shall so require, of the charges hereinafter
    provided. At the option of the Holder thereof, if Unregistered Securities
    of any series, maturity date, interest rate and original issue date are issued
    in more than one authorized denomination, except as otherwise established
    pursuant to Section 2.03, such Unregistered Securities may be exchanged for
    Unregistered Securities of such series and tenor having authorized denominations
    and an equal aggregate principal amount, upon surrender of such Unregistered
    Securities to be exchanged at the agency of the Company that shall be maintained
    for such purpose in accordance with Section 4.02, with, in the case of Unregistered
    Securities that have coupons attached, all 

 16

 unmatured coupons and all matured coupons in
    default thereto appertaining, and upon payment, if the Company shall so require,
    of the charges hereinafter provided. Registered Securities of any series
    may not be exchanged for Unregistered Securities of such series. Whenever
    any Securities are so surrendered for exchange, the Company shall execute,
    and the Trustee shall authenticate and deliver, the Securities which the
    Holder making the exchange is entitled to receive. 

      Upon surrender
    for registration of transfer of any Registered Security of a series at the
    agency of the Company that shall be maintained for that purpose in accordance
    with Section 2.05 and upon payment, if the Company shall so require, of the
    charges hereinafter provided, the Company shall execute, and the Trustee
    shall authenticate and deliver, in the name of the designated transferee
    or transferees, one or more new Registered Securities of the same series,
    of any authorized denominations and of like tenor and aggregate principal
    amount. 

      All Registered
    Securities presented for registration of transfer, exchange, redemption or
    payment shall be duly endorsed by, or be accompanied by a written instrument
    or instruments of transfer in form satisfactory to the Company and the Trustee
    duly executed by, the holder or his attorney duly authorized in writing. 

      The Company may
    require payment of a sum sufficient to cover any tax or other governmental
    charge that may be imposed in connection with any exchange or registration
    of transfer of Securities. No service charge shall be made for any such transaction. 

      Notwithstanding
    any other provision of this Section 2.07, unless and until it is exchanged
    in whole or in part for Securities in definitive registered form, a Registered
    Global Security representing all or a portion of the Securities of a series
    may not be transferred except as a whole by the Depositary for such series
    to a nominee of such Depositary or by a nominee of such Depositary to such
    Depositary or another nominee of such Depositary or by such Depositary or
    any such nominee to a successor Depositary for such series or a nominee of
    such successor Depositary.

      If at any time
    the Depositary for any Registered Global Securities of any series notifies
    the Company that it is unwilling or unable to continue as Depositary for
    such Registered Global Securities or if at any time the Depositary for such
    Registered Global Securities shall no longer be eligible under applicable
    law, the Company shall appoint a successor Depositary eligible under applicable
    law with respect to such Registered Global Securities. If a successor Depositary
    eligible under applicable law for such Registered Global Securities is not
    appointed by the Company within 90 days after the Company receives such notice
    or becomes aware of such ineligibility, the Company will execute, and the
    Trustee,

 17

 upon receipt of the Company’s order for
    the authentication and delivery of definitive Registered Securities of such
    series and tenor, will authenticate and deliver Registered Securities of
    such series and tenor, in any authorized denominations, in an aggregate principal
    amount equal to the principal amount of such Registered Global Securities,
    in exchange for such Registered Global Securities.

      The Company may
    at any time and in its sole discretion and subject to the procedures of the
    Depositary determine that any Registered Global Securities of any series
    shall no longer be maintained in global form. In such event the Company will
    execute, and the Trustee, upon receipt of the Company’s order for the
    authentication and delivery of definitive Registered Securities of such series
    and tenor, will authenticate and deliver, Registered Securities of such series
    and tenor in any authorized denominations, in an aggregate principal amount
    equal to the principal amount of such Registered Global Securities, in exchange
    for such Registered Global Securities.

      Any time the Registered
    Securities of any series are not in the form of Registered Global Securities
    pursuant to the preceding two paragraphs, the Company agrees to supply the
    Trustee with a reasonable supply of certificated Registered Securities without
    the legend required by Section 2.02 and the Trustee agrees to hold such Registered
    Securities in safekeeping until authenticated and delivered pursuant to the
    terms of this Indenture.

      If established
    by the Company pursuant to Section 2.03 with respect to any Registered Global
    Security, the Depositary for such Registered Global Security may surrender
    such Registered Global Security in exchange in whole or in part for Registered
    Securities of the same series and tenor in definitive registered form on
    such terms as are acceptable to the Company and such Depositary. Thereupon,
    the Company shall execute, and the Trustee shall authenticate and deliver,
    without service charge,

        (a) to
      the Person specified by such Depositary new Registered Securities of the
      same series and tenor, of any authorized denominations as requested by
      such Person, in an aggregate principal amount equal to and in exchange
      for such Person’s beneficial interest in the Registered Global Security;
      and

        (b) to
      such Depositary a new Registered Global Security in a denomination equal
      to the difference, if any, between the principal amount of the surrendered
      Registered Global Security and the aggregate principal amount of Registered
      Securities authenticated and delivered pursuant to clause (a) above.

 18

      Registered Securities
    issued in exchange for a Registered Global Security pursuant to this Section
    2.07 shall be registered in such names and in such authorized denominations
    as the Depositary for such Registered Global Security, pursuant to instructions
    from its direct or indirect participants or otherwise, shall instruct the
    Trustee or an agent of the Company or the Trustee. The Trustee or such agent
    shall deliver such Securities to or as directed by the Persons in whose names
    such Securities are so registered. 

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

      Notwithstanding
    anything herein or in the forms or terms of any Securities to the contrary,
    none of the Company, the Trustee or any agent of the Company or the Trustee
    shall be required to exchange any Unregistered Security for a Registered
    Security if such exchange would result in adverse Federal income tax consequences
    to the Company (such as, for example, the inability of the Company to deduct
    from its income, as computed for Federal income tax purposes, the interest
    payable on the Unregistered Securities) under then applicable United States
    Federal income tax laws. The Trustee and any such agent shall be entitled
    to rely on an Officers’ Certificate or an Opinion of Counsel in determining
    such result.

      The Registrar shall
    not be required (i) to issue, authenticate, register the transfer of or exchange
    Securities of any series for a period of 15 days before a selection of such
    Securities to be redeemed or (ii) to register the transfer of or exchange
    any Security selected for redemption in whole or in part.

      Section 2.08.
      Replacement Securities. If any mutilated
      Security or a Security with a mutilated coupon appertaining to it is surrendered
      to the Trustee, the Company shall execute and the Trustee shall authenticate
      and deliver, in exchange for such mutilated Security or in exchange for
      the Security to which a mutilated coupon appertains, a new Security of
      the same series and of like tenor and principal amount and bearing a number
      not contemporaneously outstanding, with coupons corresponding to the coupons,
      if any, appertaining to such mutilated Security or to the Security to which
      such mutilated coupon appertains. 

      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 or coupon and (ii) such
    security or indemnity as may be required by them to save each of them and
    any agent of any of them harmless, then, in the absence of notice to the
    Company or the Trustee that such Security or coupon has been acquired by
    a bona fide purchaser, the Company shall execute and the Trustee shall authenticate
    and 

 19

 deliver, in lieu of any such destroyed, lost
    or stolen Security or in exchange for the Security to which a destroyed,
    lost or stolen coupon appertains (with all appurtenant coupons not destroyed,
    lost or stolen), a new Security of the same series and of like tenor and
    principal amount and bearing a number not contemporaneously outstanding,
    with coupons corresponding to the coupons, if any, appertaining to such destroyed,
    lost or stolen Security or to the Security to which such destroyed, lost
    or stolen coupon appertains.

      In case any such
    mutilated, destroyed, lost or stolen Security or coupon has become or is
    about to become due and payable, the Company in its discretion may, instead
    of issuing a new Security, pay such Security or coupon (without surrender
    thereof except in the case of a mutilated Security or coupon) if the applicant
    for such payment shall furnish to the Company and the Trustee such security
    or indemnity as may be required by them to save each of them and any agent
    of any of them harmless, and in the case of destruction, loss or theft, evidence
    satisfactory to the Company and the Trustee and any agent of them of the
    destruction, loss or theft of such Security and the ownership thereof; provided,
    however, that the Principal of and
    any interest on Unregistered Securities shall, except as otherwise provided
    in Section 4.02, be payable only at an office or agency located outside the
    United States.

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

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

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

      Section 2.09.
      Outstanding Securities. Securities
      outstanding at any time are all Securities that have been authenticated
      by the Trustee except for those cancelled by it, those delivered to it
      for cancellation, those described in this 

 20

 Section as not outstanding and those that have
    been defeased pursuant to Section 8.05.

      If a Security is
    replaced pursuant to Section 2.08, it ceases to be outstanding unless and
    until the Trustee and the Company receive proof satisfactory to them that
    the replaced Security is held by a holder in due course. 

      If the Paying Agent
    (other than the Company or an affiliate of the Company) holds on the maturity
    date or any redemption date or date for repurchase of the Securities money
    sufficient to pay Securities payable or to be redeemed or repurchased on
    that date, then on and after that date such Securities cease to be outstanding
    and interest on them shall cease to accrue.

      A Security does
    not cease to be outstanding because the Company or one of its affiliates
    holds such Security, provided, however,
    that, in determining whether the Holders of the requisite principal amount
    of the outstanding Securities have given any request, demand, authorization,
    direction, notice, consent or waiver hereunder, Securities owned by the Company
    or any affiliate of the Company shall be disregarded and deemed not to be
    outstanding, except that, in determining whether the Trustee shall be protected
    in relying upon any such request, demand, authorization, direction, notice,
    consent or waiver, only Securities as to which a Responsible Officer of the
    Trustee has received written notice to be so owned shall be so disregarded.
    Any Securities so owned which are pledged by the Company, or by any affiliate
    of the Company, as security for loans or other obligations, otherwise than
    to another such affiliate of the Company, shall be deemed to be outstanding,
    if the pledgee is entitled pursuant to the terms of its pledge agreement
    and is free to exercise in its or his discretion the right to vote such securities,
    uncontrolled by the Company or by any such affiliate. 

      Section 2.10.
      Temporary Securities. Until definitive
      Securities of any series are ready for delivery, the Company may prepare
      and the Trustee shall authenticate temporary Securities of such series.
      Temporary Securities of any series shall be substantially in the form of
      definitive Securities of such series but may have insertions, substitutions,
      omissions and other variations determined to be appropriate by the Officers
      executing the temporary Securities, as evidenced by their execution of
      such temporary Securities. If temporary Securities of any series are issued,
      the Company will cause definitive Securities of such series to be prepared
      without unreasonable delay. After the preparation of definitive 

       Securities of
          any series, the temporary Securities of such series shall be exchangeable
          for definitive Securities of such series and tenor upon surrender of
          such temporary Securities at the office or agency of the Company designated
          for such purpose pursuant to Section 4.02, without charge to the Holder.
          Upon surrender for cancellation of any one or more temporary Securities
          of any series the Company shall execute and the Trustee shall authenticate
          and deliver in 

 21

 exchange therefor a like principal amount of
    definitive Securities of such series and tenor and authorized denominations.
    Until so exchanged, the temporary Securities of any series shall be entitled
    to the same benefits under this Indenture as definitive Securities of such
    series.

      Section 2.11.
      Cancellation. The Company at any
      time may deliver to the Trustee for cancellation any Securities previously
      authenticated and delivered hereunder which the Company may have acquired
      in any manner whatsoever, and may deliver to the Trustee for cancellation
      any Securities previously authenticated hereunder which the Company has
      not issued and sold. The Registrar, any transfer agent and the Paying Agent
      shall forward to the Trustee any Securities surrendered to them for transfer,
      exchange or payment. The Trustee shall cancel and dispose of in accordance
      with its customary procedures all Securities surrendered for transfer,
      exchange, payment or cancellation and shall deliver a certificate of disposition
      to the Company. The Company may not issue new Securities to replace Securities
      it has paid in full or delivered to the Trustee for cancellation.

      Section 2.12.
      CUSIP Numbers. The Company in issuing
      the Securities may use “CUSIP” and “CINS” numbers (if
      then generally in use), and the Trustee shall use CUSIP numbers or CINS
      numbers, as the case may be, in notices of redemption or exchange as a
      convenience to Holders and no representation shall be made as to the correctness
      of such numbers either as printed on the Securities or as contained in
      any notice of redemption or exchange. 

      Section 2.13.
      Defaulted Interest. If the Company
      defaults in a payment of interest on the Registered Securities, it shall
      pay, or shall deposit with the Paying Agent money in immediately available
      funds sufficient to pay, the defaulted interest plus (to the extent lawful)
      any interest payable on the defaulted interest (as may be specified in
      the terms thereof, established pursuant to Section 2.03) to the Persons
      who are Holders on a subsequent special record date, which shall mean the
      15th day next preceding the date fixed by the Company for the payment of
      defaulted interest, whether or not such day is a Business Day. At least
      15 days before such special record date, the Company shall mail to each
      Holder of such Registered Securities and to the Trustee a notice that states
      the special record date, the payment date and the amount of defaulted interest
      to be paid.

      Section
        2.14. Series May Include Tranches. A
        series of Securities may include one or more tranches (each a “tranche”)
        of Securities, including Securities issued in a Periodic Offering. The
        Securities of different tranches may have one or more different terms,
        including authentication dates and public offering prices, but all the
        Securities within each such tranche shall have identical terms, including
        authentication date and public offering price. Notwithstanding any other
        provision of this Indenture, with respect to Sections 2.02 (other than
        the 

 22

 fourth, sixth and seventh paragraphs thereof)
    through 2.04, 2.07, 2.08, 2.10, 3.01 through 3.05, 4.02, 6.01 through 6.14,
    8.01 through 8.07, 9.02 and Section 10.07, if any series of Securities includes
    more than one tranche, all provisions of such sections applicable to any
    series of Securities shall be deemed equally applicable to each tranche of
    any series of Securities in the same manner as though originally designated
    a series unless otherwise provided with respect to such series or tranche
    pursuant to Section 2.03. In particular, and without limiting the scope of
    the next preceding sentence, any of the provisions of such sections which
    provide for or permit action to be taken with respect to a series of Securities
    shall also be deemed to provide for and permit such action to be taken instead
    only with respect to Securities of one or more tranches within that series
    (and such provisions shall be deemed satisfied thereby), even if no comparable
    action is taken with respect to Securities in the remaining tranches of that
    series. 

ARTICLE 3

  REDEMPTION

      Section 3.01.
      Applicability of Article. The provisions
      of this Article shall be applicable to the Securities of any series which
      are redeemable before their maturity or to any sinking fund for the retirement
      of Securities of a series except as otherwise specified as contemplated
      by Section 2.03 for Securities of such series. 

      Section 3.02.
      Notice of Redemption; Partial Redemptions. Notice
      of redemption to the Holders of Registered Securities of any series to
      be redeemed as a whole or in part at the option of the Company shall be
      given by mailing notice of such redemption by first class mail, postage
      prepaid, at least 30 days and not more than 60 days prior to the date fixed
      for redemption to such Holders of Registered Securities of such series
      at their last addresses as they shall appear upon the registry books. Notice
      of redemption to the Holders of Unregistered Securities of any series to
      be redeemed as a whole or in part who have filed their names and addresses
      with the Trustee pursuant to Section 313(c)(2) of the Trust Indenture Act,
      shall be given by mailing notice of such redemption, by first class mail,
      postage prepaid, at least 30 days and not more than 60 days prior to the
      date fixed for redemption, to such Holders at such addresses as were so
      furnished to the Trustee (and, in the case of any such notice given by
      the Company, the Trustee shall make such information available to the Company
      for such purpose). Notice of redemption to all other Holders of Unregistered
      Securities of any series to be redeemed as a whole or in part shall be
      published in an Authorized Newspaper in The City of New York or with respect
      to any Security the interest on which is based on the offered quotations
      in the interbank Eurodollar market for dollar deposits in an Authorized
      Newspaper in London, in each case, once in each of three successive calendar
      weeks, the first publication to be not less than 30 

 23

 days nor more than 60 days prior to the date
    fixed for redemption. Any notice which is mailed or published in the manner
    herein provided shall be conclusively presumed to have been duly given, whether
    or not the Holder receives the notice. Failure to give 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. 

      The notice of redemption
    to each such Holder shall specify the principal amount of each Security of
    such series held by such Holder to be redeemed, the CUSIP numbers of the
    Securities to be redeemed, the date fixed for redemption, the redemption
    price, or if not then ascertainable, the manner of calculation thereof, the
    place or places of payment, that payment will be made upon presentation and
    surrender of such Securities and, in the case of Securities with coupons
    attached thereto, of all coupons appertaining thereto maturing after the
    date fixed for redemption, that such redemption is pursuant to the mandatory
    or optional sinking fund, or both, if such be the case, that interest accrued
    to the date fixed for redemption will be paid as specified in such notice
    and that on and after said date interest thereon or on the portions thereof
    to be redeemed will cease to accrue. 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 such series and tenor in principal amount equal
    to the unredeemed portion thereof will be issued. 

      The notice of redemption
    of Securities of any series to be redeemed at the option of the Company shall
    be given by the Company or, at the Company’s request, by the Trustee
    in the name and at the expense of the Company. 

      On or before 10:00
    a.m. New York City time on the redemption date or, in the case of Unregistered
    Securities, on or before 10:00 a.m. New York City time on the Business Day
    prior to the redemption date specified in the notice of redemption given
    as provided in this Section, the Company will deposit with the Trustee or
    with one or more Paying Agents (or, if the Company is acting as its own Paying
    Agent, set aside, segregate and hold in trust as provided in Section 2.06)
    an amount of money sufficient to redeem on the redemption date all the Securities
    of such series so called for redemption at the appropriate redemption price,
    together with accrued interest to the date fixed for redemption. If all of
    the outstanding Securities of a series are to be redeemed, the Company will
    deliver to the Trustee at least 10 days prior to the last date on which notice
    of redemption may be given to Holders pursuant to the first paragraph of
    this Section 3.02 (or such shorter period as shall be acceptable to the Trustee)
    an Officers’ Certificate stating that all such Securities are to be
    redeemed. If less than all the outstanding Securities of a series are to
    be redeemed, the Company will deliver to the Trustee 

 24

 at least 15 days prior to the last date on which
    notice of redemption may be given to Holders pursuant to the first paragraph
    of this Section 3.02 (or such shorter period as shall be acceptable to the
    Trustee) an Officers’
  Certificate stating the aggregate principal amount of such Securities to be
  redeemed. In the case of any redemption of Securities (a) prior to the expiration
  of any restriction on such redemption provided in the terms of such Securities
  or elsewhere in this Indenture, or (b) pursuant to an election of the Company
  which is subject to a condition specified in the terms of such Securities or
  elsewhere in this Indenture, the Company shall deliver to the Trustee, prior
  to the giving of any notice of redemption to Holders pursuant to this Section,
  an Officers’ Certificate evidencing compliance with such restriction or
  condition.

      If less than all
    the Securities of a series are to be redeemed, the Trustee shall select,
    pro rata, by lot or in such manner as it shall deem appropriate and fair,
    Securities of such series to be redeemed in whole or in part. Securities
    may be redeemed in part in principal amounts equal to authorized denominations
    for Securities of such series. The Trustee shall promptly notify the Company
    in writing of the Securities of such series selected for redemption and,
    in the case of any Securities of such series selected for partial redemption,
    the principal amount thereof to be redeemed. For all purposes of this Indenture,
    unless the context otherwise requires, all provisions relating to the redemption
    of Securities shall relate, in the case of any Security redeemed or to be
    redeemed only in part, to the portion of the principal amount of such Security
    which has been or is to be redeemed. 

      Section 3.03.
      Payment Of Securities Called For Redemption. If
      notice of redemption has been given as above provided, the Securities or
      portions of Securities specified in such notice shall become due and payable
      on the date and at the place stated in such notice at the applicable redemption
      price, together with interest accrued to the date fixed for redemption,
      and on and after such date (unless the Company shall default in the payment
      of such Securities at the redemption price, together with interest accrued
      to such date) interest on the Securities or portions of Securities so called
      for redemption shall cease to accrue, and the unmatured coupons, if any,
      appertaining thereto shall be void and, except as provided in Sections
      7.12 and 8.02, such Securities shall cease from and after the date fixed
      for redemption to be entitled to any benefit under this Indenture, and
      the Holders thereof shall have no right in respect of such Securities except
      the right to receive the redemption price thereof and unpaid interest to
      the date fixed for redemption. On presentation and surrender of such Securities
      at a place of payment specified in said notice, together with all coupons,
      if any, appertaining thereto maturing after the date fixed for redemption,
      said Securities or the specified portions thereof shall be paid and redeemed
      by the Company at the applicable redemption price, together with interest
      accrued thereon to the date fixed for redemption; provided that payment
      of interest becoming due on or prior 

 25

 to the date fixed for redemption shall be payable
    in the case of Securities with coupons attached thereto, to the Holders of
    the coupons for such interest upon surrender thereof, and in the case of
    Registered Securities, to the Holders of such Registered Securities registered
    as such on the relevant record date subject to the terms and provisions of
    Sections 2.04 and 2.13 hereof.

      If any Security
    called for redemption shall not be so paid upon surrender thereof for redemption,
    the principal shall, until paid or duly provided for, bear interest from
    the date fixed for redemption at the rate of interest or Yield to Maturity
    (in the case of an Original Issue Discount Security) borne by such Security. 

      If any Security
    with coupons attached thereto is surrendered for redemption and is not accompanied
    by all appurtenant coupons maturing after the date fixed for redemption,
    the surrender of such missing coupon or coupons may be waived by the Company
    and the Trustee, if there be furnished to each of them such security or indemnity
    as they may require to save each of them harmless. 

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

      Section 3.04.
      Exclusion of Certain Securities from Eligibility for Selection for Redemption. Securities
      shall be excluded from eligibility for selection for redemption if they
      are identified by registration and certificate number in a written statement
      signed by an authorized officer of the Company and delivered to the Trustee
      at least 40 days prior to the last date on which notice of redemption may
      be given as being owned of record and beneficially by, and not pledged
      or hypothecated by, either (a) the Company or (b) an entity specifically
      identified in such written statement as directly or indirectly controlling
      or controlled by or under direct or indirect common control with the Company.

      Section
        3.05. Mandatory and Optional Sinking
        Funds. 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 the Securities of any series is herein referred to as an “optional
        sinking fund payment”. The date on which a sinking fund payment
        is to be made is herein referred to as the “sinking fund payment
        date”. 

      In lieu of making
    all or any part of any mandatory sinking fund payment with respect to any
    series of Securities in cash, the Company may at its option (a) 

 26 

 deliver to the Trustee Securities of such series
    theretofore purchased or otherwise acquired (except through a mandatory sinking
    fund payment) by the Company or receive credit for Securities of such series
    (not previously so credited) theretofore purchased or otherwise acquired
    (except as aforesaid) by the Company and delivered to the Trustee for cancellation
    pursuant to Section 2.11, (b) receive credit for optional sinking fund payments
    (not previously so credited) made pursuant to this Section, or (c) receive
    credit for Securities of such series (not previously so credited) redeemed
    by the Company at the option of the Company pursuant to the terms of such
    Securities or through any optional sinking fund payment. Securities so delivered
    or credited shall be received or credited by the Trustee at the sinking fund
    redemption price specified in such Securities. 

      On or before the
    sixtieth day next preceding each sinking fund payment date for any series,
    or such shorter period as shall be acceptable to the Trustee, the Company
    will deliver to the Trustee an Officers’ Certificate (a) specifying
    the portion of the mandatory sinking fund payment to be satisfied by payment
    of cash and the portion to be satisfied by credit of specified Securities
    of such series and the basis for such credit, (b) stating that none of the
    specified Securities of such series has theretofore been so credited, (c)
    stating that no defaults in the payment of interest or Events of Default
    with respect to such series have occurred (which have not been waived or
    cured) and are continuing and (d) stating whether or not the Company intends
    to exercise its right to make an optional sinking fund payment with respect
    to such series and, if so, specifying the amount of such optional sinking
    fund payment which the Company intends to pay on or before the next succeeding
    sinking fund payment date. Any Securities of such series to be credited and
    required to be delivered to the Trustee in order for the Company to be entitled
    to credit therefor as aforesaid which have not theretofore been delivered
    to the Trustee shall be delivered for cancellation pursuant to Section 2.11
    to the Trustee with such Officers’ Certificate (or reasonably promptly
    thereafter if acceptable to the Trustee). Such Officers’
  Certificate shall be irrevocable and upon its receipt by the Trustee the Company
  shall become unconditionally obligated to make all the cash payments or delivery
  of Securities therein referred to, if any, on or before the next succeeding
  sinking fund payment date. Failure of the Company, on or before any such sixtieth
  day, to deliver such Officer’s Certificate and Securities specified in
  this paragraph, if any, shall not constitute a default but shall constitute,
  on and as of such date, the irrevocable election of the Company (i) that the
  mandatory sinking fund payment for such series due on the next succeeding sinking
  fund payment date shall be paid entirely in cash without the option to deliver
  or credit Securities of such series in respect thereof and (ii) that the Company
  will make no optional sinking fund payment with respect to such series as provided
  in this Section. 

      If the sinking
    fund payment or payments (mandatory or optional or both) to be made in cash
    on the next succeeding sinking fund payment date plus any 

 27

 unused balance of any preceding sinking fund
    payments made in cash shall exceed $50,000 (or a lesser sum if the Company
    shall so request with respect to the Securities of any series), such cash
    shall be applied on the next succeeding sinking fund payment date to the
    redemption of Securities of such series at the sinking fund redemption price
    thereof together with accrued interest thereon to the date fixed for redemption.
    If such amount shall be $50,000 (or such lesser sum) or less and the Company
    makes no such request then it shall be carried over until a sum in excess
    of $50,000 (or such lesser sum) is available. The Trustee shall select, in
    the manner provided in Section 3.02, for redemption on such sinking fund
    payment date a sufficient principal amount of Securities of such series to
    absorb said cash, as nearly as may be, and shall (if requested in writing
    by the Company) inform the Company of the serial numbers of the Securities
    of such series (or portions thereof) so selected. Securities shall be excluded
    from eligibility for redemption under this Section if they are identified
    by registration and certificate number in an Officers’ Certificate delivered
    to the Trustee at least 60 days prior to the sinking fund payment date as
    being owned of record and beneficially by, and not pledged or hypothecated
    by either (a) the Company or (b) an entity specifically identified in such
    Officers’ Certificate as directly or indirectly controlling or controlled
    by or under direct or indirect common control with the Company. The Trustee,
    in the name and at the expense of the Company (or the Company, if it shall
    so request the Trustee in writing) shall cause notice of redemption of the
    Securities of such series to be given in substantially the manner provided
    in Section 3.02 (and with the effect provided in Section 3.03) for the redemption
    of Securities of such series in part at the option of the Company. The amount
    of any sinking fund payments not so applied or allocated to the redemption
    of Securities of such series shall be added to the next cash sinking fund
    payment for such series and, together with such payment, shall be applied
    in accordance with the provisions of this Section. Any and all sinking fund
    moneys held on the stated maturity date of the Securities of any particular
    series (or earlier, if such maturity is accelerated), which are not held
    for the payment or redemption of particular Securities of such series shall
    be applied, together with other moneys, if necessary, sufficient for the
    purpose, to the payment of the Principal of, and interest on, the Securities
    of such series at maturity. 

      On or before 10:00
    a.m. New York City time on each sinking fund payment date or, in the case
    of Unregistered Securities, 10:00 a.m. New York City time on the Business
    Day prior to the sinking fund payment date, the Company shall pay to the
    Trustee in cash or shall otherwise provide for the payment of all interest
    accrued to the date fixed for redemption on Securities to be redeemed on
    the next following sinking fund payment date. 

      The Trustee shall
    not redeem or cause to be redeemed any Securities of a series with sinking
    fund moneys or mail any notice of redemption of Securities of such series
    by operation of the sinking fund during the continuance of a Default in 

 28

 payment of interest on such Securities or of
    any Event of Default except that, where the mailing of notice of redemption
    of any Securities shall theretofore have been made, the Trustee shall redeem
    or cause to be redeemed such Securities, provided that it shall have received
    from the Company a sum sufficient for such redemption. 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
    the sinking fund, shall, during the continuance of such Default or Event
    of Default, be deemed to have been collected under Article 6 and held for
    the payment of all such Securities. In case such Event of Default shall have
    been waived as provided in Section 6.04 or the Default cured on or before
    the sixtieth day preceding the sinking fund payment date in any year, such
    moneys shall thereafter be applied on the next succeeding sinking fund payment
    date in accordance with this Section to the redemption of such Securities. 

ARTICLE 4

  COVENANTS

      Section 4.01.
      Payment of Securities. The Company
      shall pay the Principal of and interest on the Securities on the dates
      and in the manner provided in the Securities and this Indenture. The interest
      on Securities with coupons attached (together with any additional amounts
      payable pursuant to the terms of such Securities) shall be payable only
      upon presentation and surrender of the several coupons for such interest
      installments as are evidenced thereby as they severally mature. The interest
      on any temporary Unregistered Securities (together with any additional
      amounts payable pursuant to the terms of such Securities) shall be paid,
      as to the installments of interest evidenced by coupons attached thereto,
      if any, only upon presentation and surrender thereof, and, as to the other
      installments of interest, if any, only upon presentation of such Unregistered
      Securities for notation thereon of the payment of such interest. The interest
      on Registered Securities (together with any additional amounts payable
      pursuant to the terms of such Securities) shall be payable only to the
      Holders thereof (subject to Section 2.04) and at the option of the Company
      may be paid by mailing checks for such interest payable to or upon the
      written order of such Holders at their last addresses as they appear on
      the Security Register of the Company.

      Notwithstanding
    any provisions of this Indenture and the Securities of any series to the
    contrary, if the Company and a Holder of any Registered Security so agree,
    payments of interest on, and any portion of the Principal of, such Holder’s
    Registered Security (other than interest payable at maturity or on any redemption
    or repayment date or the final payment of Principal on such Security) shall
    be made by the Paying Agent, upon receipt from the Company of immediately
    available funds by 11:00 A.M., New York City time (or such other time as
    may be agreed to between the Company and the Paying Agent), directly to the
    Holder of 

 29

 such Security (by Federal funds wire transfer
    or otherwise) if the Holder has delivered written instructions to the Trustee
    15 days prior to such payment date requesting that such payment will be so
    made and designating the bank account to which such payments shall be so
    made and in the case of payments of Principal, surrenders the same to the
    Trustee in exchange for a Security or Securities aggregating the same principal
    amount as the unredeemed principal amount of the Securities surrendered.
    The Trustee shall be entitled to rely on the last instruction delivered by
    the Holder pursuant to this Section 4.01 unless a new instruction is delivered
    15 days prior to a payment date. The Company will indemnify and hold each
    of the Trustee and any Paying Agent harmless against any loss, liability
    or expense (including attorneys’ fees) resulting from any act or omission
    to act on the part of the Company or any such Holder in connection with any
    such agreement or from making any payment in accordance with any such agreement.

      The Company shall
    pay interest on overdue Principal, and interest on overdue installments of
    interest, to the extent lawful, at the rate per annum specified in the Securities. 

      Section 4.02.
      Maintenance of Office or Agency. The
      Company will maintain in the Borough of Manhattan, The City of New York,
      or Chicago, Illinois an office or agency where Securities may be surrendered
      for registration of transfer or exchange or for presentation for payment
      and where notices and demands to or upon the Company in respect of the
      Securities and this Indenture may be served. The Company hereby initially
      designates the Corporate Trust Office of the Trustee, located in Chicago,
      Illinois, as such office or agency of the Company. The Company will give
      prompt written notice to the Trustee of the location, and any change in
      the location, of such office or agency. If at any time the Company shall
      fail to maintain any such required office or agency or shall fail to furnish
      the Trustee with the address thereof, such presentations, surrenders, notices
      and demands may be made or served at the address of the Trustee set forth
      in Section 10.02. 

      The Company
      will maintain one or more agencies in a city or cities located outside
      the United States (including any city in which such an agency is required
      to be maintained under the rules of any stock exchange on which the Securities
      of any series are listed) where the Unregistered Securities, if any, of
      each series and coupons, if any, appertaining thereto may be presented
      for payment. No payment on any Unregistered Security or coupon will be
      made upon presentation of such Unregistered Security or coupon at an agency
      of the Company within the United States nor will any payment be made by
      transfer to an account in, or by mail to an address in, the United States
      unless, pursuant to applicable United States laws and regulations then
      in effect, such payment can be made without adverse tax consequences to
      the Company. Notwithstanding the foregoing, if full payment in United States
      Dollars (“Dollars”) at each agency 

 30

 maintained by the Company outside the United
    States for payment on such Unregistered Securities or coupons appertaining
    thereto is illegal or effectively precluded by exchange controls or other
    similar restrictions, payments in Dollars of Unregistered Securities of any
    series and coupons appertaining thereto which are payable in Dollars may
    be made at an agency of the Company maintained in the Borough of Manhattan,
    The City of New York, or Chicago, Illinois. 

      The Company may
    also from time to time designate one or more other offices or agencies where
    the Securities of any series may be presented or surrendered for any or all
    such purposes and may from time to time rescind such designations; provided
    that no such designation or rescission shall in any manner relieve the Company
    of its obligation to maintain an office or agency in the Borough of Manhattan,
    The City of New York, or Chicago, Illinois for such purposes. The Company
    will give prompt written notice to the Trustee of any such designation or
    rescission and of any change in the location of any such other office or
    agency. 

      Section 4.03.
      Securityholders’ Lists. The
      Company will furnish or cause to be furnished to the Trustee a list in
      such form as the Trustee may reasonably require of the names and addresses
      of the holders of the Securities pursuant to Section 312 of the Trust Indenture
      Act of 1939 (a) semi-annually not more than 15 days after each record date
      for the payment of semi-annual interest on the Securities, as hereinabove
      specified, as of such record date, and (b) at such other times as the Trustee
      may request in writing, within thirty days after receipt by the Company
      of any such request as of a date not more than 15 days prior to the time
      such information is furnished.

      Section 4.04.
      Certificate to Trustee. The Company
      will furnish to the Trustee annually, on or before a date not more than
      four months after the end of its fiscal year (which, on the date hereof,
      is a calendar year), a brief certificate (which need not contain the statements
      required by Section 10.04) from its principal executive, financial or accounting
      officer as to his or her knowledge of the compliance of the Company with
      all conditions and covenants under this Indenture (such compliance to be
      determined without regard to any period of grace or requirement of notice
      provided under this Indenture) which certificate shall comply with the
      requirements of the Trust Indenture Act. 

      Section 4.05.
      Reports by the Company. The Company
      covenants to file with the Trustee, within 15 days after the Company is
      required to file the same with the Commission, copies of the annual reports
      and of the information, documents, and other reports which the Company
      may be required to file with the Commission pursuant to Section 13 or Section
      15(d) of the Exchange Act. 

 31

      Section 4.06. Additional
      Amounts. If the Securities of a
      series provide for the payment of additional amounts, at least 10 days
      prior to the first interest payment date with respect to that series of
      Securities and at least 10 days prior to each date of payment of Principal
      of or interest on the Securities of that series if there has been a change
      with respect to the matters set forth in the below-mentioned Officers’ Certificate,
      the Company shall furnish to the Trustee and the principal paying agent,
      if other than the Trustee, an Officers’ Certificate instructing the
      Trustee and such paying agent whether such payment of Principal of or interest
      on the Securities of that series shall be made to Holders of the Securities
      of that series without withholding or deduction for or on account of any
      tax, assessment or other governmental charge described in the Securities
      of that series. If any such withholding or deduction shall be required,
      then such Officers’ Certificate shall specify by country the amount,
      if any, required to be withheld or deducted on such payments to such Holders
      and shall certify the fact that additional amounts will be payable and
      the amounts so payable to each Holder, and the Company shall pay to the
      Trustee or such paying agent the additional amounts required to be paid
      by this Section. The Company covenants to indemnify the Trustee and any
      paying agent for, and to hold them harmless against, any loss, liability
      or expense reasonably incurred without negligence or bad faith on their
      part arising out of or in connection with actions taken or omitted by any
      of them in reliance on any Officers’ Certificate furnished pursuant
      to this Section. 

      Whenever in this
    Indenture there is mentioned, in any context, the payment of the Principal
    of or interest or any other amounts on, or in respect of, any Security of
    any series, such mention shall be deemed to include mention of the payment
    of additional amounts provided by the terms of such series established hereby
    or pursuant hereto to the extent that, in such context, additional amounts
    are, were or would be payable in respect thereof pursuant to such terms,
    and express mention of the payment of additional amounts (if applicable)
    in any provision hereof shall not be construed as excluding the payment of
    additional amounts in those provisions hereof where such express mention
    is not made.

      When Company May Merge, Etc. The

      transfer, lease or otherwise dispose of all or substantially all of its
      property and assets (in one transaction or a series of related transactions)
      to, any Person unless either (x) the Company shall be the continuing Person
      or (y) the Person (if other than the Company) formed by such consolidation
      or into which the Company is merged or to which properties and assets of
      the Company shall be sold, conveyed, transferred or leased shall be a

    the laws of the United States of America or any jurisdiction thereof and
    shall expressly assume, by a supplemental indenture, executed and delivered
    to the Trustee, all of the obligations of the Company on all of the Securities
    and under this Indenture and the Company in the case of clauses (x) and (y)
    shall have delivered to the Trustee (A) an Opinion of Counsel stating that
    such consolidation, merger or sale, conveyance, transfer or lease and such
    supplemental indenture (if any) complies with this provision and that all
    conditions precedent provided for herein relating to such transaction have

    enforceable against such entity in accordance with its terms, subject to
    customary exceptions and (B) an Officers’ Certificate to the effect
    that immediately after giving effect to such transaction, no Default shall

ARTICLE 6

  DEFAULT AND REMEDIES

      Section 6.01.
      Events of Default. An “Event
      of Default” shall occur with
      respect to the Securities of any series if: 

      (a) the
    Company defaults in the payment of the Principal of any Security of such
    series when the same becomes due and payable at maturity, upon acceleration,
    redemption or mandatory repurchase, including as a sinking fund installment,
    or otherwise; 

      (b) the
    Company defaults in the payment of interest on any Security of such series
    when the same becomes due and payable, and such default continues for a period
    of 30 days; 

      (c) the
    Company defaults in the performance of or breaches any other covenant or
    agreement of the Company in this Indenture with respect to any 

 33

 Security of such series or in the Securities
    of such series and such default or breach continues for a period of 30 consecutive
    days after written notice to the Company by the Trustee or to the Company
    and the Trustee by the Holders of 25% or more in aggregate principal amount
    of the Securities of all series affected thereby specifying such default
    or breach and requiring it to be remedied and stating that such notice is
    a “Notice of Default” hereunder; 

      (d) 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 similar official) of the Company or for any substantial part of its property
    or ordering the winding up or liquidation of its affairs, and such decree
    or order shall remain unstayed and in effect for a period of 60 consecutive
    days; 

      (e) the

    to the appointment of or taking possession by a receiver, liquidator, assignee,

    effects any general assignment for the benefit of creditors; or 

      (f) any
    other Event of Default established pursuant to Section 2.03 with respect
    to the Securities of such series occurs. 

      Section 6.02.
      Acceleration. (a) If an Event of
      Default other than as described in clauses (d) or (e) of Section 6.01 with
      respect to the Securities of any series then outstanding occurs and is
      continuing, then, and in each and every such case, except for any series
      of Securities the principal of which shall have already become due and
      payable, either the Trustee or the Holders of not less than 25% in aggregate
      principal amount of the Securities of any such series then outstanding
      hereunder (each such series treated as a separate class) by notice in writing
      to the Company (and to the Trustee if given by Securityholders), may declare
      the entire principal (or, if the Securities of any such series are Original
      Issue Discount Securities, such portion of the principal amount as may
      be specified in the terms of such series established pursuant to Section
      2.03) of all Securities of such series, and the interest accrued thereon,
      if any, to be due and payable immediately, and upon any such declaration
      the same shall become immediately due and payable. 

      (b) If
    an Event of Default described in clause (d) or (e) of Section 6.01 occurs
    and is continuing, then the principal amount (or, if any Securities are Original
    Issue Discount Securities, such portion of the principal as may be specified
    in the terms thereof established pursuant to Section 2.03) of all the 

 34

 Securities then outstanding and interest accrued
    thereon, if any, shall be and become immediately due and payable, without
    any notice or other action by any Holder or the Trustee, to the full extent
    permitted by applicable law. 

      The foregoing provisions,
    however, are subject to the condition that if, at any time after the principal
    (or, if the Securities are Original Issue Discount Securities, such portion
    of the principal as may be specified in the terms thereof established pursuant
    to Section 2.03) of the Securities of any series (or of all the Securities,
    as the case may be) shall have been so declared or become 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
    installments of interest upon all the Securities of each such series (or
    of all the Securities, as the case may be) and the principal of any and all
    Securities of each such series (or of all the Securities, as the case may
    be) which shall have become due otherwise than by acceleration (with interest
    upon such principal and, to the extent that payment of such interest is enforceable
    under applicable law, on overdue installments of interest, at the same rate
    as the rate of interest or Yield to Maturity (in the case of Original Issue
    Discount Securities) specified in the Securities of each such series to the
    date of such payment or deposit) and such amount as shall be sufficient to
    cover all amounts owing the Trustee under Section 7.07, and if any and all
    Events of Default under the Indenture, other than the non-payment of the
    principal of Securities which shall have become due by acceleration, shall
    have been cured, waived or otherwise remedied as provided herein, then and
    in every such case the Holders of a majority in aggregate principal amount
    of all the then outstanding Securities of all such series that have been
    accelerated (voting as a single class), by written notice to the Company
    and to the Trustee, may waive all defaults with respect to all such series
    (or with respect to all the 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. 

      For all purposes
    under this Indenture, if a portion of the principal of any Original Issue
    Discount Securities shall have been accelerated and declared or become due
    and payable pursuant to the provisions hereof, then, from and after such
    declaration, unless such declaration has been rescinded and annulled, the
    principal amount of such Original Issue Discount Securities shall be deemed,
    for all purposes hereunder, to be such portion of the principal thereof as
    shall be due and payable as a result of such acceleration, and payment of
    such portion of the principal thereof as shall be due and payable as a result
    of such acceleration, together with interest, if any, thereon and all other
    amounts owing thereunder, shall constitute payment in full of such Original
    Issue Discount Securities. 

 35

      Section 6.03.
      Other Remedies. If a payment default
      or an Event of Default with respect to the Securities of any series occurs
      and is continuing, the Trustee may pursue, in its own name or as trustee
      of an express trust, any available remedy by proceeding at law or in equity
      to collect the payment of Principal of and interest on the Securities of
      such series or to enforce the performance of any provision of the Securities
      of such series or this Indenture. 

      The Trustee may
    maintain a proceeding even if it does not possess any of the Securities or
    does not produce any of them in the proceeding. 

      Section 6.04.
      Waiver of Past Defaults. Subject
      to Sections 6.02, 6.07 and 9.02, the Holders of at least a majority in
      principal amount (or, if the Securities are Original Issue Discount Securities,
      such portion of the principal as is then accelerable under Section 6.02)
      of the outstanding Securities of all series affected (voting as a single
      class), by notice to the Trustee, may waive an existing Default or Event
      of Default with respect to the Securities of such series and its consequences,
      except a Default in the payment of Principal of or interest on any Security
      as specified in clauses (a) or (b) of Section 6.01 or in respect of a covenant
      or provision of this Indenture which cannot be modified or amended without
      the consent of the Holder of each outstanding Security affected. Upon any
      such waiver, such Default shall cease to exist, and any Event of Default
      with respect to the Securities of such series arising therefrom shall be
      deemed to have been cured, for every purpose of this Indenture; but no
      such waiver shall extend to any subsequent or other Default or Event of
      Default or impair any right consequent thereto. 

      Section 6.05.
      Control by Majority. Subject to
      Sections 7.01 and 7.02(e), the Holders of at least a majority in aggregate
      principal amount (or, if any Securities are Original Issue Discount Securities,
      such portion of the principal as is then accelerable under Section 6.02)
      of the outstanding Securities of all series affected (voting as a single
      class) may 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
      by this Indenture; provided, that the Trustee may refuse to follow any
      direction that conflicts with law or this Indenture, that may involve the
      Trustee in personal liability or that the Trustee determines in good faith
      may be unduly prejudicial to the rights of Holders not joining in the giving
      of such direction; and provided further, that the Trustee may take any
      other action it deems proper that is not inconsistent with any directions
      received from Holders of Securities pursuant to this Section 6.05. 

      Section 6.06.
      Limitation on Suits. No Holder of
      any Security of any series may institute any proceeding, judicial or otherwise,
      with respect to this 

 36

 Indenture or the Securities of such series, or
    for the appointment of a receiver or trustee, or for any other remedy hereunder,
    unless: 

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

        (b) the
      Holders of at least 25% in aggregate principal amount of outstanding Securities
      of all such series affected shall have made written request to the Trustee
      to institute proceedings in respect of such Event of Default in its own
      name as Trustee hereunder; 

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

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

        (e) during
      such 60-day period, the Holders of a majority in aggregate principal amount
      of the outstanding Securities of all such affected series have not given
      the Trustee a direction that is inconsistent with such written request. 

      A Holder may not
    use this Indenture to prejudice the rights of another Holder or to obtain
    a preference or priority over such other Holder. 

      Section 6.07.
      Rights of Holders to Receive Payment. Notwithstanding
      any other provision of this Indenture, the right of any Holder of a Security
      to receive payment of Principal of or interest, if any, on such Holder’s
      Security on or after the respective due dates expressed on such Security,
      or to bring 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 6.08.
      Collection Suit by Trustee. If an
      Event of Default with respect to the Securities of any series in payment
      of Principal or interest specified in clause (a) or (b) of Section 6.01
      occurs and is continuing, the Trustee may recover judgment in its own name
      and as trustee of an express trust against the Company for the whole amount
      (or such portion thereof as specified in the terms established pursuant
      to Section 2.03 of Original Issue Discount Securities) of Principal of,
      and accrued interest remaining unpaid on, together with interest on overdue
      Principal of, and, to the extent that payment of such interest is lawful,
      interest on overdue installments of interest on, the Securities of such
      series, in each case at the rate or Yield to Maturity (in the case of Original
      Issue Discount 

 37

 Securities) specified in such Securities, and
    such further amount as shall be sufficient to cover all amounts owing the
    Trustee under Section 7.07. 

      Section 6.09.
      Trustee May File Proofs of Claim. The
      Trustee may 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
      (including any claim for amounts due the Trustee under Section 7.07) and
      the Holders allowed in any judicial proceedings relative to the Company
      (or any other obligor on the Securities), its creditors or its property
      and shall be entitled and empowered to collect and receive any moneys,
      securities or other property payable or deliverable upon conversion or
      exchange of the Securities or upon any such claims and to distribute the
      same, and any custodian, receiver, assignee, trustee, liquidator, sequestrator
      or other similar official in any such judicial proceeding is hereby authorized
      by each Holder to make such payments to the Trustee and, in the event that
      the Trustee shall consent to the making of such payments directly to the
      Holders, to pay to the Trustee any amount due to it under Section 7.07.
      Nothing herein contained shall be deemed to empower the Trustee to authorize
      or consent to, or accept or adopt on behalf of any Holder, any plan of
      reorganization, arrangement, adjustment or composition affecting the Securities
      or the rights of any Holder thereof, or to authorize the Trustee to vote
      in respect of the claim of any Holder in any such proceeding. 

      Section 6.10.
      Application of Proceeds. Any moneys
      collected by the Trustee pursuant to this Article in respect of the Securities
      of any series shall be applied in the following order at the date or dates
      fixed by the Trustee and, in case of the distribution of such moneys on
      account of Principal or interest, upon presentation of the several Securities
      and coupons appertaining to such Securities in respect of which moneys
      have been collected and noting thereon the payment, or issuing Securities
      of such series and tenor in reduced principal amounts in exchange for the
      presented Securities of such series and tenor if only partially paid, or
      upon surrender thereof if fully paid: 

        FIRST: To the
      payment of all amounts due the Trustee under Section 7.07 applicable to
      the Securities of such series in respect of which moneys have been collected; 

        SECOND: In case
      the principal of the Securities of such series in respect of which moneys
      have been collected shall not have become and be then due and payable,
      to the payment of interest on the Securities of such series in default
      in the order of the maturity of the installments of such interest, with
      interest (to the extent that such interest has been collected by the Trustee)
      upon the overdue installments of interest at the same rate as the rate
      of interest or Yield to Maturity (in the case of Original Issue Discount
      Securities) specified in such Securities, such 

 38

   payments to be made ratably to the persons
      entitled thereto, without discrimination or preference; 

        THIRD: In case
      the principal of the Securities of such series in respect of which moneys
      have been collected shall have become and shall be then due and payable,
      to the payment of the whole amount then owing and unpaid upon all the Securities
      of such series for Principal and interest, with interest upon the overdue
      Principal, and (to the extent that such interest has been collected by
      the Trustee) upon overdue installments of interest at the same rate as
      the rate of interest or Yield to Maturity (in the case of Original Issue
      Discount Securities) specified in the Securities of such series; and in
      case such moneys shall be insufficient to pay in full the whole amount
      so due and unpaid upon the Securities of such series, then to the payment
      of such Principal and interest or Yield to Maturity, without preference
      or priority of Principal over interest or Yield to Maturity, or of interest
      or Yield to Maturity over Principal, or of any installment of interest
      over any other installment of interest, or of any Security of such series
      over any other Security of such series, ratably to the aggregate of such
      Principal and accrued and unpaid interest or Yield to Maturity; and 

        FOURTH: To the
      payment of the remainder, if any, to the Company or any other person lawfully
      entitled thereto. 

      Section 6.11.
      Restoration of Rights and Remedies. If
      the Trustee or any Holder has instituted any proceeding to enforce any
      right or remedy under this Indenture and such proceeding has been discontinued
      or abandoned for any reason, or has been determined adversely to the Trustee
      or to such Holder, then, and in every such case, subject to any determination
      in such proceeding, the Company, the Trustee and the Holders shall be restored
      to their former positions hereunder and thereafter all rights and remedies
      of the Company, Trustee and the Holders shall continue as though no such
      proceeding had been instituted. 

      Section 6.12. Undertaking
      for Costs. In any suit for the enforcement
      of any right or remedy under this Indenture or in any suit against the
      Trustee for any action taken or omitted by it as Trustee, in either case
      in respect to the Securities of any series, a court may require any party
      litigant in such suit (other than the Trustee) to file an undertaking to
      pay the costs of the suit, and the court may assess reasonable costs, including
      reasonable attorneys’ fees, against any party litigant (other than
      the Trustee) in the suit having due regard to the merits and good faith
      of the claims or defenses made by the party litigant. This Section 6.12
      does not apply to a suit by a Holder pursuant to Section 6.07, a suit instituted
      by the Trustee or a suit by Holders of more than 10% in principal amount
      of the outstanding Securities of such series.

 39

      Section 6.13.
      Rights and Remedies Cumulative. Except
      as otherwise provided with respect to the replacement or payment of mutilated,
      destroyed, lost or wrongfully taken Securities in Section 2.08, 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 6.14.
      Delay or Omission not Waiver. No
      delay or omission of the Trustee or of any Holder 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 6 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. 

ARTICLE 7

  TRUSTEE 

      Section 7.01.
      General. The duties and responsibilities
      of the Trustee shall be as provided by the Trust Indenture Act and as set
      forth herein. Notwithstanding the foregoing,
      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, unless it receives indemnity satisfactory to it against any
      loss, liability or expense. 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 Article 7. 

      Section 7.02.
      Certain Rights of Trustee. Subject
      to Trust Indenture Act Sections 315(a) through (d): 

        (a) the
      Trustee may rely and shall be protected in acting or refraining from acting
      upon any resolution, certificate, Officers’
    Certificate, Opinion of Counsel (or both), statement, instrument, opinion,
    report, notice, request, direction, consent, order, bond, debenture, note,
    other evidence of indebtedness or other paper or document believed by it
    to be genuine and to have been signed or presented by the proper person or
    persons. The Trustee need not investigate any fact or matter stated in the 

 40

   document, but the Trustee, in its discretion,
      may make such further inquiry or investigation into such facts or matters
      as it may see fit; 

        (b) before
      the Trustee acts or refrains from acting, it may require an Officers’ Certificate
      and/or an Opinion of Counsel, which shall conform to Section 10.04 and
      shall cover such other matters as the Trustee may reasonably request. The
      Trustee shall not be liable for any action it takes or omits to take in
      good faith in reliance on such certificate or opinion. Subject to Sections
      7.01 and 7.02, whenever in the administration of the trusts of this Indenture
      the Trustee shall deem it necessary or desirable that a matter be proved
      or established prior to taking or suffering or omitting any action hereunder,
      such matter (unless other evidence in respect thereof be herein specifically
      prescribed) may, in the absence of negligence or bad faith on the part
      of the Trustee, be deemed to be conclusively proved and established by
      an Officers’ Certificate delivered to the Trustee, and such certificate,
      in the absence of negligence or bad faith on the part of the Trustee, shall
      be full warrant to the Trustee for any action taken, suffered or omitted
      by it under the provisions of this Indenture upon the faith thereof; 

        (c) the
      Trustee may act through its attorneys and agents not regularly in its employ
      and shall not be responsible for the misconduct or negligence of any agent
      or attorney appointed with due care; 

        (d) any
      request, direction, order or demand of the Company mentioned herein shall
      be sufficiently evidenced by an Officers’
    Certificate (unless other evidence in respect thereof be herein specifically
    prescribed); and any Board Resolution may be evidenced to the Trustee by
    a copy thereof certified by the Secretary or an Assistant Secretary of the
    Company; 

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

        (f) the
      Trustee shall not be liable for any action it takes or omits to take in
      good faith that it believes to be authorized or within its rights or powers
      or for any action it takes or omits to take in accordance with the direction
      of the Holders in accordance with Section 6.05 relating to the time, method
      and place of conducting any proceeding for any 

 41

   remedy available to the Trustee, or exercising
      any trust or power conferred upon the Trustee, under this Indenture;

        (g) the
      Trustee may consult with counsel and the written 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; and 

        (h) prior
      to the occurrence of an Event of Default hereunder and after the curing
      or waiving of all Events of Default, the Trustee shall not be bound to
      make any investigation into the facts or matters stated in any resolution,
      certificate, Officers’ Certificate, Opinion of Counsel, Board Resolution,
      statement, instrument, opinion, report, notice, request, consent, order,
      approval, appraisal, bond, debenture, note, coupon, security, or other
      paper or document unless requested in writing so to do by the Holders of
      not less than a majority in aggregate principal amount of the Securities
      of all series affected then outstanding; provided that, if the payment
      within a reasonable time to the Trustee of the costs, expenses or liabilities
      likely to be incurred by it in the making of such investigation is, in
      the opinion of the Trustee, not reasonably assured to the Trustee by the
      security afforded to it by the terms of this Indenture, the Trustee may
      require reasonable indemnity against such expenses or liabilities as a
      condition to proceeding. 

      Section 7.03.
      Individual Rights of Trustee. The
      Trustee, in its individual or any other capacity, may become the owner
      or pledgee of Securities and may otherwise deal with the Company or its
      Affiliates with the same rights it would have if it were not the Trustee.
      Any Agent may do the same with like rights. However, the Trustee is subject
      to Trust Indenture Act Sections 310(b) and 311. For purposes of Trust Indenture
      Act Section 311(b)(4) and (6), the following terms shall mean: 

      (a) “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; and 

      (b) “self-liquidating
      paper” means any draft, bill
      of 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, 

 42

 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. 

      Section 7.04.
      Trustee's Disclaimer. The recitals
      contained herein and in the Securities (except the Trustee’s certificate
      of authentication) shall be taken as statements of the Company and not
      of the Trustee and the Trustee assumes no responsibility for the correctness
      of the same. Neither the Trustee nor any of its agents (a) makes any representation
      as to the validity or adequacy of this Indenture or the Securities and
      (b) shall be accountable for the Company’s use or application of the
      proceeds from the Securities. 

      Section 7.05.
      Notice of Default. If any Default
      with respect to the Securities of any series occurs and is continuing and
      if such Default is known to the actual knowledge of a Responsible Officer
      with the Corporate Trust Department of the Trustee, the Trustee shall give
      to each Holder of Securities of such series notice of such Default within
      90 days after it occurs (a) if any Unregistered Securities of such series
      are then outstanding, to the Holders thereof, by publication at least once
      in an Authorized Newspaper in the Borough of Manhattan, The City of New
      York and at least once in an Authorized Newspaper in London and (b) to
      all Holders of Securities of such series in the manner and to the extent
      provided in Section 313(c) of the Trust Indenture Act, unless such Default
      shall have been cured or waived before the mailing or publication of such
      notice; provided, however, that, except in the case of a Default in the
      payment of the Principal of or interest on any Security, the Trustee shall
      be protected in withholding such notice if the Trustee in good faith determines
      that the withholding of such notice is in the interests of the Holders. 

      Section 7.06.
      Reports by Trustee to Holders. The
      Trustee shall transmit to Holders such reports concerning the Trustee and
      its actions under this Indenture as may be required pursuant to the Trust
      Indenture Act at the times and in the manner provided pursuant thereto.
      If required by Section 313(a) of the Trust Indenture Act, the Trustee shall,
      within 60 days after each May 15 following the date of this Indenture,
      deliver to Holders a brief report, dated as of such May 15, which complies
      with the provisions of such Section 313(a). 

      A copy of each
    such report shall, at the time of such transmission to Holders, be filed
    by the Trustee with each stock exchange upon which any Securities are listed,
    with the Commission and with the Company. The Company will promptly notify
    the Trustee when any Securities are listed on any stock exchange. 

 43

      Section 7.07.
      Compensation and Indemnity. The
      Company shall pay to the Trustee such compensation as shall be agreed upon
      in writing from time to time for its services. The compensation of the
      Trustee shall not be limited by any law on compensation of a Trustee of
      an express trust. The Company shall reimburse the Trustee and any predecessor
      Trustee upon request for all reasonable out-of-pocket expenses, disbursements
      and advances incurred or made by the Trustee or such predecessor Trustee.
      Such expenses shall include the reasonable compensation and expenses of
      the Trustee’s or such predecessor Trustee’s agents, counsel and
      other persons not regularly in their employ. 

      The Company shall
    indemnify the Trustee and any predecessor Trustee for, and hold them harmless
    against, any loss or liability or expense incurred by them without negligence
    or bad faith on their part arising out of or in connection with the acceptance
    or administration of this Indenture and the Securities or the issuance of
    the Securities or of series thereof or the trusts hereunder and the performance
    of duties under this Indenture and the Securities, including the costs and
    expenses of defending themselves against or investigating any claim or liability
    and of complying with any process served upon them or any of their officers
    in connection with the exercise or performance of any of their powers or
    duties under this Indenture and the Securities. 

      To secure the Company’s
    payment obligations in this Section 7.07, the Trustee shall have a lien prior
    to the Securities on all money or property held or collected by the Trustee,
    in its capacity as Trustee, except money or property held in trust to pay
    Principal of, and interest on particular Securities. 

      The obligations
    of the Company under this Section to compensate and indemnify the Trustee
    and each predecessor Trustee and to pay or reimburse the Trustee and each
    predecessor Trustee for expenses, disbursements and advances shall constitute
    additional indebtedness hereunder and shall survive the satisfaction and
    discharge of this Indenture or the rejection or termination of this Indenture
    under bankruptcy law. Such additional indebtedness shall be a senior claim
    to that of the Securities upon all property and funds held or collected by
    the Trustee as such, except funds held in trust for the benefit of the Holders
    of particular Securities or coupons, and the Securities are hereby subordinated
    to such senior claim. Without prejudice to any other rights available to
    the Trustee under applicable law, if the Trustee renders services and incurs
    expenses following an Event of Default under Section 6.01(d) or Section 6.01(e)
    hereof, the parties hereto and the holders by their acceptance of the Securities
    hereby agree that such expenses are intended to constitute expenses of administration
    under any bankruptcy law. 

      Section 7.08.
      Replacement of Trustee. A resignation
      or removal of the Trustee as Trustee with respect to the Securities of
      any series and appointment of 

 44

 a successor Trustee as Trustee with respect to
    the Securities of any series shall become effective only upon the successor
    Trustee’s acceptance of appointment as provided in this Section 7.08. 

      The Trustee may
    resign as Trustee with respect to the Securities of any series at any time
    by so notifying the Company in writing. The Holders of a majority in principal
    amount of the outstanding Securities of any series may remove the Trustee
    as Trustee with respect to the Securities of such series by so notifying
    the Trustee in writing and may appoint a successor Trustee with respect thereto
    with the consent of the Company. The Company may remove the Trustee as Trustee
    with respect to the Securities of any series if: (i) the Trustee is no longer
    eligible under Section 7.11 of this Indenture; (ii) the Trustee is adjudged
    a bankrupt or insolvent; (iii) a receiver or other public officer takes charge
    of the Trustee or its property; or (iv) the Trustee becomes incapable of
    acting. 

      If the Trustee
    resigns or is removed as Trustee with respect to the Securities of any series,
    or if a vacancy exists in the office of Trustee with respect to the Securities
    of any series for any reason, the Company shall promptly appoint a successor
    Trustee with respect thereto. Within one year after the successor Trustee
    takes office, the Holders of a majority in principal amount of the outstanding
    Securities of such series may appoint a successor Trustee in respect of such
    Securities to replace the successor Trustee appointed by the Company. If
    the successor Trustee with respect to the Securities of any series does not
    deliver its written acceptance required by Section 7.09 within 30 days after
    the retiring Trustee resigns or is removed, the retiring Trustee, the Company
    or the Holders of a majority in principal amount of the outstanding Securities
    of such series may petition any court of competent jurisdiction for the appointment
    of a successor Trustee with respect thereto. 

      The Company shall
    give notice of any resignation and any removal of the Trustee with respect
    to the Securities of any series and each appointment of a successor Trustee
    in respect of the Securities of such series to all Holders of Securities
    of such series. Each notice shall include the name of the successor Trustee
    and the address of its Corporate Trust Office. 

      Notwithstanding
    replacement of the Trustee with respect to the Securities of any series pursuant
    to this Section 7.08 and Section 7.09, the Company’s obligations under
    Section 7.07 shall continue for the benefit of the retiring Trustee.

      Section 7.09. Acceptance
      of Appointment by Successor. In
      case of the appointment hereunder of a successor Trustee with respect to
      all Securities, every such successor Trustee so appointed shall execute,
      acknowledge and deliver to the Company and to the retiring Trustee an instrument
      accepting such appointment, and thereupon the resignation or removal of
      the retiring Trustee shall become 

 45

 effective and such successor Trustee, without
    any further act, deed or conveyance, shall become vested with all the rights,
    powers, trusts and duties of the retiring Trustee; but, on the request of
    the Company or the successor Trustee, such retiring Trustee shall, upon payment
    of its charges and subject to the lien provided for in Section 7.07, execute
    and deliver an instrument transferring to such successor Trustee all the
    rights, powers and trusts of the retiring Trustee and shall duly assign,
    transfer and deliver to such successor Trustee all property and money held
    by such retiring Trustee hereunder. 

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

      Upon request of
    any such successor Trustee, the Company shall execute any and all instruments
    for more fully and certainly vesting in and confirming to such successor
    Trustee all such rights, powers and trusts referred to in the first or second
    preceding paragraph, as the case may be. 

 46

      No successor Trustee
    shall accept its appointment unless at the time of such acceptance such successor
    Trustee shall be eligible under this Article and qualified under Section
    310(b) of the Trust Indenture Act. 

      Section 7.10.
      Successor Trustee By Merger, Etc. If
      the Trustee consolidates with, merges or converts into, or transfers all
      or substantially all of its corporate trust business to, another corporation
      or national banking association, the resulting, surviving or transferee
      corporation or national banking association without any further act shall
      be the successor Trustee with the same effect as if the successor Trustee
      had been named as the Trustee herein. 

      Section 7.11.
      Eligibility. This Indenture shall
      always have a Trustee who satisfies the requirements of Trust Indenture
      Act Section 310(a). The Trustee shall have a combined capital and surplus
      of at least $25,000,000 as set forth in its most recent published annual
      report of condition. 

      Section 7.12.
      Money Held in Trust. 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 and except for money held in trust under Article 8 of this
      Indenture.

      (other than Securities of such series which have been destroyed, lost or
      stolen and which have been replaced or paid as provided in Section 2.08)
      as and when the same shall have become due and payable, or (b) the Company
      shall have delivered to the Trustee for cancellation all Securities of
      any series theretofore authenticated (other than any Securities of such
      series which shall have been destroyed, lost or stolen and which shall
      have been replaced or paid as provided in Section 2.08) or (c) (i) all
      the securities of such series not theretofore delivered to the Trustee
      for cancellation shall have become due and payable, or are by their terms

      deposited or caused to be deposited with the Trustee as trust funds the
      entire amount in cash (other than moneys repaid by the Trustee or any paying
      agent to the Company in accordance with Section 8.04) or U.S. Government
      Obligations, maturing as to principal and interest in such amounts and
      at such times as will insure (without consideration of

 47

 the reinvestment of such interest) the availability
    of cash, or a combination thereof, sufficient to pay at maturity or upon
    redemption all Securities of such series (other than any Securities of such
    series which shall have been destroyed, lost or stolen and which shall have

    may be, and if, in any such case, the Company shall also pay or cause to
    be paid all other sums payable hereunder by the Company with respect to Securities
    of such series, then this Indenture shall cease to be of further effect with

    of transfer and exchange of securities of such series, and the Company’s
    right of optional redemption, if any, (ii) substitution of mutilated, defaced,
    destroyed, lost or stolen Securities, (iii) rights of holders to receive
    payments of principal thereof and interest thereon, upon the original stated
    due dates therefor (but not upon acceleration) and remaining rights of the
    holders to receive mandatory sinking fund payments, if any, (iv) the rights,
    obligations and immunities of the Trustee hereunder and (v) the rights of
    the Securityholders of such series as beneficiaries hereof with respect to
    the property so deposited with the Trustee payable to all or any of them),
    and the Trustee, on demand of the Company accompanied by an Officers’ Certificate
    and an Opinion of Counsel and at the cost and expense of the Company, shall
    execute proper instruments acknowledging such satisfaction of and discharging
    this Indenture with respect to such series; provided, that the rights of
    Holders of the Securities to receive amounts in respect of Principal of and
    interest on the Securities held by them shall not be delayed longer than
    required by then-applicable mandatory rules or policies of any securities
    exchange upon which the Securities are listed. The Company agrees to reimburse
    the Trustee for any costs or expenses thereafter reasonably and properly
    incurred and to compensate the Trustee for any services thereafter reasonably
    and properly rendered by the Trustee in connection with this Indenture or
    the Securities of such series.

      to Section 8.04, all moneys (including U.S. Government Obligations and
      the proceeds thereof) deposited with the Trustee pursuant to Section 8.01,

      the payment, either directly or through any paying agent to the Holders
      of the particular Securities of such series for the payment or redemption
      of which such moneys have been deposited with the Trustee, of all sums
      due and to become due thereon for Principal and interest; but such money
      need not be segregated from other funds except to the extent required by
      law. 

      Section 8.03.
      Repayment of Moneys Held by Paying Agent. In
      connection with the satisfaction and discharge of this Indenture with respect
      to Securities of any series, all moneys then held by any paying agent under
      the provisions of this 

 48

 Indenture with respect to such series of Securities
    shall, upon demand of the Company, be repaid to it or paid to the Trustee
    and thereupon such paying agent shall be released from all further liability
    with respect to such moneys. 

      Section 8.04.
      Return of Moneys Held by Trustee and Paying Agent Unclaimed for Two Years. Any
      moneys deposited with or paid to the Trustee or any paying agent for the
      payment of the Principal of or interest on any Security of any series and
      not applied but remaining unclaimed for two years after the date upon which
      such Principal or interest shall have become due and payable, shall, upon
      the written request of the Company and unless otherwise required by mandatory
      provisions of applicable escheat or abandoned or unclaimed property law,
      be repaid to the Company by the Trustee for such series or such paying
      agent, and the Holder of the Security of such series shall, unless otherwise
      required by mandatory provisions of applicable escheat or abandoned or
      unclaimed property laws, thereafter look only to the Company for any payment
      which such Holder may be entitled to collect, and all liability of the
      Trustee or any paying agent with respect to such moneys shall thereupon
      cease. 

      Section 8.05.
      Defeasance and Discharge of Indenture. The
      Company shall be deemed to have paid and shall be discharged from any and
      all obligations in respect of the Securities of any series, on the 123rd
      day after the deposit referred to in clause (i) hereof has been made, and
      the provisions of this Indenture shall no longer be in effect with respect
      to the Securities of such series (and the Trustee, at the expense of the
      Company, shall execute proper instruments acknowledging the same), except
      as to: (a) rights of registration of transfer and exchange, and the Company’s
      right of optional redemption, (b) substitution of apparently mutilated,
      defaced, destroyed, lost or stolen Securities, (c) rights of holders to
      receive payments of principal thereof and interest thereon, upon the original
      stated due dates therefor (but not upon acceleration), (d) the rights,

        (i) with
      reference to this provision the Company has deposited or caused to be irrevocably
      deposited with the Trustee (or another qualifying trustee satisfying the
      requirements of Section 7.11) as trust funds in trust, specifically pledged
      as security for, and dedicated solely to, the benefit of the Holders of
      the Securities of such series, (A) money in an amount, or (B) U.S. Government
      Obligations which through the payment of interest and principal in respect
      thereof in accordance with their terms will provide not later than one
      day before the due date of any payment referred to in subclause (x) or
      (y) of this clause (i) money in an amount, or (C) a combination thereof,
      sufficient, in the opinion of a nationally 

 49

   recognized firm of independent public accountants
      expressed in a written certification thereof delivered to the Trustee,
      to pay and discharge without consideration of the reinvestment of such
      interest and after payment of all federal, state and local taxes or other
      charges and assessments in respect thereof payable by the Trustee (x) the
      principal of, premium, if any, and each installment of interest on the
      outstanding Securities of such series on the due dates thereof and (y)
      any mandatory sinking fund payments or analogous payments applicable to
      the Securities of such series on the day on which such payments are due
      and payable in accordance with the terms of Securities of such series and
      the Indenture with respect to the Securities of such series; 

        (ii) the

      to the effect that Holders of Securities of such series will not recognize
      income, gain or loss for federal income tax purposes as a result of the
      Company’s exercise of its option under this Section 8.05 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
      and discharge had not occurred, which Opinion of Counsel must be based
      upon a ruling of the Internal Revenue Service to the same effect or a change
      in applicable federal income tax law or related treasury regulations after
      the date of this Indenture or (y) a ruling directed to the Trustee received
      from the Internal Revenue Service to the same effect as the aforementioned
      Opinion of Counsel and (B) an Opinion of Counsel to the effect that the
      creation of the defeasance trust does not violate the Investment Company
      Act of 1940 and after the passage of 123 days following the deposit, the
      trust fund will not be subject to the effect of Section 547 of the U.S.
      Bankruptcy Code or Section 15 of the New York Debtor and Creditor Law;

        (iii) immediately
      after giving effect to such deposit on a pro forma basis, no Event of Default,
      or event that after the giving of notice or lapse of time or both would
      become an Event of Default, shall have occurred and be continuing on the
      date of such deposit or during the period ending on the 123rd day after
      the date of such deposit, and such deposit shall not result in a breach
      or violation of, or constitute a default under, any other agreement or
      instrument to which the Company is a party or by which the Company is bound;

        (iv) if
      at such time the Securities of such series are listed on a national securities
      exchange, the Company has delivered to the Trustee an Opinion of Counsel
      to the effect that the Securities of such series will not be delisted as
      a result of such deposit, defeasance and discharge;

 50

        (v) the
      Company shall have delivered to the Trustee an Officers’ Certificate
      and an Opinion of Counsel, each stating that all conditions precedent to
      the defeasance and discharge under this Section have been complied with;
      and 

        (vi) if
      the Securities of such series are to be redeemed prior to the final maturity
      thereof (other than from mandatory sinking fund payments or analogous payments),
      notice of such redemption shall have been duly given pursuant to this Indenture
      or provision therefor satisfactory to the Trustee shall have been made.

      to any covenants established pursuant to Section 2.03(r)) and clause (f)
      of Section 6.01 shall be deemed not to be an Event of Default, if

      (a) with
    reference to this Section 8.06, the Company has deposited or caused to be
    irrevocably deposited with the Trustee (or another qualifying trustee satisfying
    the requirements of Section 7.11) as trust funds in trust, specifically pledged
    as security for, and dedicated solely to, the benefit of the Holders of the
    Securities of such series and the Indenture with respect to the Securities
    of such series, (i) money in an amount or (ii) U.S. Government Obligations
    which through the payment of interest and principal in respect thereof in
    accordance with their terms will provide not later than one day before the
    due dates thereof or earlier redemption (irrevocably provided for under agreements
    satisfactory to the Trustee), as the case may be, of any payment referred
    to in subclause (x) or (y) of this clause (a) money in an amount, or (iii)
    a combination thereof, 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 without consideration
    of the reinvestment of such interest and after payment of all federal, state
    and local taxes or other charges and assessments in respect thereof payable

    and of Securities of such series and the Indenture with respect to the Securities
    of such series; 

 51

      (b) the
    Company has delivered to the Trustee (i) an Opinion of Counsel to the effect
    that Holders of Securities of such series will not recognize income, gain
    or loss for federal income tax purposes as a result of the Company’s
    exercise of its option under this Section 8.06 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 and defeasance had not occurred
    and (ii) an Opinion of Counsel to the effect that the creation of the defeasance
    trust does not violate the Investment Company Act of 1940 and after the passage
    of 123 days following the deposit, the trust fund will not be subject to
    the effect of Section 547 of the U.S. Bankruptcy Code or Section 15 of the

      (c) immediately
    after giving effect to such deposit on a pro forma basis, no Event of Default,
    or event that after the giving of notice or lapse of time or both would become
    an Event of Default, shall have occurred and be continuing on the date of
    such deposit or during the period ending on the 123rd day after the date
    of such deposit, and such deposit shall not result in a breach or violation
    of, or constitute a default under, any other agreement or instrument to which
    the Company is a party or by which the Company is bound;

      (d) if
    at such time the Securities of such series are listed on a national securities
    exchange, the Company has delivered to the Trustee an Opinion of Counsel

      Reinstatement. If the Trustee or
      paying agent is unable to apply any monies or U.S. Government Obligations
      in accordance with Article 8 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 this Article until
      such time as the Trustee or paying agent is permitted to apply all such
      monies or U.S. Government Obligations in accordance with Article 8; provided,
      however, that if the Company has
      made any payment of Principal of or interest on any Securities because
      of the reinstatement of its obligations, the Company shall be subrogated
      to the rights of the Holders of such Securities to receive such payment
      from the monies or U.S. Government Obligations held by the Trustee or paying
      agent. 

      Section 8.08. Indemnity. The
    Company shall pay and indemnify the Trustee (or other qualifying trustee,

    Obligations deposited pursuant to Section 8.01, 8.05 or 8.06 or the principal
    or interest received in respect thereof other than any such tax, fee or other

    any coupons appertaining thereto. 

      Section 8.09. Excess
      Funds. Anything in this Article
      8 to the contrary notwithstanding, the Trustee shall deliver or pay to
      the Company from time to time upon request of the Company, any money or
      U.S. Government Obligations (or other property and any proceeds therefrom)
      held by it as provided in Section 8.01, 8.05 or 8.06 which, in the opinion
      of a nationally recognized firm of Independent Public Accountants expressed
      in a written certification thereof delivered to the Trustee, are in excess
      of the amount thereof which would then be required to be deposited to effect
      a discharge or defeasance, as applicable, in accordance with this Article
      8. 

      Section 8.10. Qualifying
      Trustee. Any trustee appointed pursuant
      to Section 8.05 or 8.06 for the purpose of holding money or U.S. Government
      Obligations deposited pursuant to such Sections shall be appointed under
      an agreement in form acceptable to the Trustee and shall provide to the
      Trustee a certificate, upon which certificate the Trustee shall be entitled
      to conclusively rely, that all conditions precedent provided for herein
      to the related defeasance have been complied with. In no event shall the
      Trustee be liable for any acts or omissions of said trustee

      thereby (all such series voting as a separate class) by written notice
      to the Trustee may waive future compliance by the Company with any provision
      of this Indenture or the Securities of such series. 

      Notwithstanding
    the provisions of this Section 9.02, without the consent of each Holder affected
    thereby, an amendment or waiver, including a waiver pursuant to Section 6.04,
    may not: 

      (a) change
    the stated maturity of the Principal of, or any sinking fund obligation or
    any installment of interest on, such Holder’s Security,

      (b) reduce
    the Principal amount thereof or the rate of interest thereon (including any
    amount in respect of original issue discount); 

      (c) reduce
    the above stated percentage of outstanding Securities the consent of whose
    holders is necessary to modify or amend the Indenture with respect to the
    Securities of the relevant series; and 

      (d) reduce
    the percentage in principal amount of outstanding Securities of the relevant
    series the consent of whose Holders is required for any supplemental indenture
    or for any waiver of compliance with certain provisions of 

 54

 this Indenture or certain Defaults and their
    consequences provided for in this Indenture. 

      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 Holders of Securities of such series with respect to such covenant or
    provision, shall be deemed not to affect the rights under this Indenture
    of the Holders of Securities of any other series or of the coupons appertaining
    to such Securities. 

      It shall not be
    necessary for the consent of any Holder under this Section 9.02 to approve
    the particular form of any proposed amendment, supplement or waiver, but
    it shall be sufficient if such consent approves the substance thereof. 

      After an amendment,
    supplement or waiver under this Section 9.02 becomes effective, the Company
    shall give to the Holders affected thereby a notice briefly describing the
    amendment, supplement or waiver. The Company will mail supplemental indentures
    to Holders upon request. Any failure of the Company to mail 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 9.03.
      Revocation and Effect of Consent. Until
      an amendment or waiver becomes effective, a consent to it by a Holder 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 Security of
      the consenting Holder, 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 its Security or portion of its Security. Such revocation
      shall be effective only if the Trustee receives the notice of revocation
      before the date the amendment, supplement or waiver becomes effective.
      An amendment, supplement or waiver shall become effective with respect
      to any Securities affected thereby on receipt by the Trustee of written
      consents from the requisite Holders of outstanding Securities affected
      thereby. 

      The Company may,
    but shall not be obligated to, fix a record date (which may be not less than
    five nor more than 60 days prior to the solicitation of consents) for the
    purpose of determining the Holders of the Securities of any series affected
    entitled to consent to any amendment, supplement or waiver. If a record date
    is fixed, then, notwithstanding the immediately preceding paragraph, those
    Persons who were such Holders at such record date (or their duly designated
    proxies) and only those Persons shall be entitled to consent to such amendment,
    supplement or waiver or to revoke any consent previously given, whether or
    not such Persons continue to be such Holders after such record date. No such
    consent shall be valid or effective for more than 90 days after such record
    date. 

 55

      After an amendment,
    supplement or waiver becomes effective with respect to the Securities of
    any series affected thereby, it shall bind every Holder of such Securities
    unless it is of the type described in any of clauses (a) through (d) of Section
    9.02. In case of an amendment or waiver of the type described in clauses
    (a) through (d) of Section 9.02, the amendment or waiver shall bind each
    such Holder who has consented to it and every subsequent Holder of a Security
    that evidences the same indebtedness as the Security of the consenting Holder. 

      Section 9.04.
      Notation on or Exchange of Securities. If
      an amendment, supplement or waiver changes the terms of any Security, the
      Trustee may require the Holder thereof to deliver it to the Trustee. The
      Trustee may place an appropriate notation on the Security about the changed
      terms and return it to the Holder and the Trustee may place an appropriate
      notation on any Security of such series thereafter authenticated. Alternatively,
      if the Company or the Trustee so determines, the Company in exchange for
      the Security shall issue and the Trustee shall authenticate a new Security
      of the same series and tenor that reflects the changed terms. 

      Section 9.05.
      Trustee to Sign Amendments, Etc. The
      Trustee shall be entitled to receive, and shall be fully protected in relying
      upon, an Opinion of Counsel stating that the execution of any amendment,
      supplement or waiver authorized pursuant to this Article 9 is authorized
      or permitted by this Indenture, stating that all requisite consents have
      been obtained or that no consents are required and stating that such supplemental
      indenture constitutes the legal, valid and binding obligation of the Company,
      enforceable against the Company in accordance with its terms, subject to
      customary exceptions. The Trustee may, but shall not be obligated to, execute
      any such amendment, supplement or waiver that affects the Trustee’s
      own rights, duties or immunities under this Indenture or otherwise. 

      Section 9.06.
      Conformity with Trust Indenture Act. Every
      supplemental indenture executed pursuant to this Article 9 shall conform
      to the requirements of the Trust Indenture Act as then in effect.

      qualified under the Trust Indenture Act.

      Section 10.02.

      received or (b) if mailed by first class mail 5 days after mailing, or
      (c) as between the Company and the Trustee if sent by facsimile transmission,
      when transmission is confirmed, in each case addressed as follows: 

if to the Company:

      Attention: Worldwide Securities Services 

  

      The Company or
    the Trustee by written notice to the other may designate additional or different
    addresses for subsequent notices or communications. 

      Any notice or communication
    shall be sufficiently given to Holders of any Unregistered Securities, by
    publication at least once in an Authorized Newspaper in The City of New York,
    or with respect to any Security the interest on which is based on the offered
    quotations in the interbank Eurodollar market for dollar deposits at least
    once in an Authorized Newspaper in London, and by mailing to the Holders
    thereof who have filed their names and addresses with the Trustee pursuant
    to Section 313(c)(2) of the Trust Indenture Act at such addresses as were
    so furnished to the Trustee and to Holders of Registered Securities by mailing
    to such Holders at their addresses as they shall appear on the Security Register.
    Notice mailed shall be sufficiently given if so mailed within the time prescribed.
    Copies of any such communication or notice to a Holder shall also be mailed
    to the Trustee and each Agent at the same time. 

      Failure to mail
    a notice or communication to a Holder or any defect in it shall not affect
    its sufficiency with respect to other Holders. Except as otherwise provided
    in this Indenture, if a notice or communication is mailed in the manner provided
    in this Section 10.02, it is duly given, whether or not the addressee receives
    it. 

 57

      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. 

      In case it shall
    be impracticable to give notice as herein contemplated, then such notification
    as shall be made with the approval of the Trustee shall constitute a sufficient
    notification for every purpose hereunder. 

      Section 10.03.
      Certificate and Opinion as to Conditions Precedent. Upon
      any request or application by the Company to the Trustee to take any action
      under this Indenture, the Company shall furnish to the Trustee: 

        (a) an
      Officers’ Certificate stating that, in the opinion of the signers,
      all conditions precedent, if any, provided for in this Indenture relating
      to the proposed action have been complied with; and 

        (b) an
      Opinion of Counsel stating that, in the opinion of such counsel, all such
      conditions precedent have been complied with. 

      Section 10.04.
      Statements Required in Certificate or Opinion. Each
      certificate or opinion with respect to compliance with a condition or covenant
      provided for in this Indenture (other than the certificate required by
      Section 4.04) shall include: 

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

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

        (c) a
      statement that, in the opinion of each such person, 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 

        (d) a
      statement as to whether or not, in the opinion of each such person, such
      condition or covenant has been complied with; provided,
      however, that, with respect to matters
      of fact, an Opinion of Counsel may rely on an Officers’ Certificate
      or certificates of public officials. 

 58

      Section 10.05.
      Evidence of Ownership. The Company,
      the Trustee and any agent of the Company or the Trustee may deem and treat
      the Holder of any Unregistered Security and the Holder of any coupon as
      the absolute owner of such Unregistered Security or coupon (whether or
      not such Unregistered Security or coupon shall be overdue) for the purpose
      of receiving payment thereof or on account thereof and for all other purposes,
      and neither the Company, the Trustee, nor any agent of the Company or the
      Trustee shall be affected by any notice to the contrary. The fact of the
      holding by any Holder of an Unregistered Security, and the identifying
      number of such Security and the date of his holding the same, may be proved
      by the production of such Security or by a certificate executed by any
      trust company, bank, banker or recognized securities dealer wherever situated
      satisfactory to the Trustee, if such certificate shall be deemed by the
      Trustee to be satisfactory. Each such certificate shall be dated and shall
      state that on the date thereof a Security bearing a specified identifying
      number was deposited with or exhibited to such trust company, bank, banker
      or recognized securities dealer by the person named in such certificate.
      Any such certificate may be issued in respect of one or more Unregistered
      Securities specified therein. The holding by the person named in any such
      certificate of any Unregistered Securities specified therein shall be presumed
      to continue for a period of one year from the date of such certificate
      unless at the time of any determination of such holding (1) another certificate
      bearing a later date issued in respect of the same Securities shall be
      produced or (2) the Security specified in such certificate shall be produced
      by some other Person, or (3) the Security specified in such certificate
      shall have ceased to be outstanding. Subject to Article 7, the fact and
      date of the execution of any such instrument and the amount and numbers
      of Securities held by the Person so executing such instrument may also
      be proven in accordance with such reasonable rules and regulations as may
      be prescribed by the Trustee or in any other manner which the Trustee may
      deem sufficient. 

      The Company, the
    Trustee and any agent of the Company or the Trustee may deem and treat the
    person in whose name any Registered Security shall be registered upon the
    Security Register for such series as the absolute owner of such Registered
    Security (whether or not such Registered Security shall be overdue and notwithstanding
    any notation of ownership or other writing thereon) for the purpose of receiving
    payment of or on account of the Principal of and, subject to the provisions
    of this Indenture, interest on such Registered Security and for all other
    purposes; and neither the Company nor the Trustee nor any agent of the Company
    or the Trustee shall be affected by any notice to the contrary. 

      Section 10.06.
      Rules by Trustee, Paying Agent or Registrar. The
      Trustee may make reasonable rules for action by or at a meeting of Holders.
      The Paying Agent or Registrar may make reasonable rules for its functions. 

 59

      Section 10.07.
      Payment Date Other Than a Business Day. Except
      as otherwise provided with respect to a series of Securities, if any date
      for payment of Principal or interest on any Security shall not be a Business
      Day at any place of payment, then payment of Principal of or interest on
      such Security, as the case may be, need not be made on such date, but may
      be made on the next succeeding Business Day at any place of payment with
      the same force and effect as if made on such date and no interest shall
      accrue in respect of such payment for the period from and after such date. 

      Section 10.08.
      Governing Law. The laws of the State
      of New York shall govern this Indenture and the Securities. 

      Section 10.09.
      No Adverse Interpretation of Other Agreements. This
      Indenture may not be used to interpret another indenture or loan or debt
      agreement of the Company or any Subsidiary of the Company. Any such indenture
      or agreement may not be used to interpret this Indenture. 

      Section 10.10.
      Successors. All agreements of the
      Company in this Indenture and the Securities shall bind its successors.
      All agreements of the Trustee in this Indenture shall bind its successors. 

      Section 10.11.
      Duplicate Originals. The parties
      may sign any number of copies of this Indenture. Each signed copy shall
      be an original, but all of them together represent the same agreement. 

      Section 10.12.
      Separability. 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 10.13.
      Table of Contents, Headings, Etc. The
      Table of Contents and headings of the Articles and Sections of this Indenture
      have been inserted for convenience of reference only, are not to be considered
      a part hereof and shall in no way modify or restrict any of the terms and
      provisions hereof. 

      Section 10.14.
      Incorporators, Stockholders, Officers and Directors of Company Exempt from
      Individual Liability. No recourse
      under or upon any obligation, covenant or agreement contained in this Indenture
      or any indenture supplemental hereto, or in any Security or any coupons
      appertaining thereto, or because of any indebtedness evidenced thereby,
      shall be had against any incorporator, as such or against any past, present
      or future stockholder, officer, director or employee, as such, of the Company
      or of any successor, either directly or through the Company or any successor,
      under any rule of law, statute or constitutional provision or by the enforcement
      of any assessment or by any legal or equitable proceeding or otherwise,
      all such liability being expressly waived and

 60

 released by the acceptance of the Securities
    and the coupons appertaining thereto by the holders thereof and as part of
    the consideration for the issue of the Securities and the coupons appertaining
    thereto. 

      Section
        10.15. 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 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 Business Day, then, to the extent
        permitted by applicable law, 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 Business 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, or any recovery pursuant to any judgment (whether or not
        entered in accordance with subsection (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.

ARTICLE 2 

  THE SECURITIES

      Section
        2.01. Form and Dating. The
        Securities of each series shall be substantially in such form or forms
        (not inconsistent with this Indenture) as shall be established by or
        pursuant to one or more Board Resolutions or in one or more indentures
        supplemental hereto, in each case with such appropriate insertions, omissions,
        substitutions and other variations as are required or permitted by this 

 9 

 Indenture and may have imprinted or otherwise
    reproduced thereon such legend or legends or endorsements, not inconsistent
    with the provisions of this Indenture, as may be required to comply with
    any law, or with any rules of any securities exchange or usage, all as may
    be determined by the officers executing such Securities as evidenced by their
    execution of the Securities. Unless otherwise so established, Unregistered
    Securities shall have coupons attached. 

      Section
        2.02. Execution And Authentication. Two
        Officers shall execute the Securities and one Officer shall execute the
        coupons appertaining thereto for the Company by facsimile or manual signature
        in the name and on behalf of the Company. The seal of the Company, if
        any, shall be reproduced on the Securities. If an Officer whose signature
        is on a Security or coupon appertaining thereto no longer holds that
        office at the time the Security is authenticated, the Security and such
        coupon shall nevertheless be valid.

      The Trustee,
      at the expense of the Company, may appoint an authenticating agent (the “Authenticating
      Agent”) to authenticate Securities. The 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 Authenticating Agent. 

      A Security
      and the coupons appertaining thereto shall not be valid until the Trustee
      or Authenticating Agent manually signs the certificate of authentication
      on the Security or on the Security to which such coupon appertains by an
      authorized officer. The signature shall be conclusive evidence that the
      Security or the Security to which the coupon appertains has been authenticated
      under this Indenture. 

      At any time
      and from time to time after the execution and delivery of this Indenture,
      the Company may deliver Securities of any series having attached thereto
      appropriate coupons, if any, executed by the Company to the Trustee for
      authentication together with the applicable documents referred to below
      in this Section, and the Trustee shall thereupon authenticate and deliver
      such Securities to or upon the written order of the Company. In authenticating
      any Securities of a series, the Trustee shall be entitled to receive prior
      to the authentication of any Securities of such series, and (subject to
      Article 7) shall be fully protected in relying upon, unless and until such
      documents have been superseded or revoked:

        (a) any
      Board Resolution and/or executed supplemental indenture referred to in
      Sections 2.01 and 2.03 by or pursuant to which the forms and terms of the
      Securities of that series were established; 

        (b) an
      Officers’ Certificate setting forth the form or forms and terms of
      the Securities, stating that the form or forms and terms of the Securities
      of such series have been, or, in the case of a Periodic Offering, 

10 

   will be when established in accordance with
      such procedures as shall be referred to therein, established in compliance
      with this Indenture; and

        (c) an
      Opinion of Counsel substantially to the effect that the form or forms and
      terms of the Securities of such series have been, or, in the case of a
      Periodic Offering, will be when established in accordance with such procedures
      as shall be referred to therein, established in compliance with this Indenture
      and that the supplemental indenture, to the extent applicable, and Securities
      have been duly authorized and, if executed and authenticated in accordance
      with the provisions of the Indenture and delivered to and duly paid for
      by the purchasers thereof on the date of such opinion, would be entitled
      to the benefits of the Indenture and would be valid and binding obligations
      of the Company, enforceable against the Company in accordance with their
      respective terms, subject to bankruptcy, insolvency, reorganization, receivership,
      moratorium and other similar laws affecting creditors’ rights generally,
      general principles of equity, and covering such other matters as shall
      be specified therein and as shall be reasonably requested by the Trustee. 

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

      Notwithstanding
      the provisions of Sections 2.01 and 2.02, if, in connection with a Periodic
      Offering, all Securities of a series are not to be originally issued at
      one time, it shall not be necessary to deliver the Board Resolution otherwise
      required pursuant to Section 2.01 or the written order, Officers’ Certificate
      and Opinion of Counsel otherwise required pursuant to Section 2.02 at or
      prior to the authentication of each Security of such series if such documents
      are delivered at or prior to the authentication upon original issuance
      of the first Security of such series to be issued. 

      With respect
      to Securities of a series offered in a Periodic Offering, the Trustee may
      rely, as to the authorization by the Company of any of such Securities,
      the forms and terms thereof and the legality, validity, binding effect
      and enforceability thereof, upon the Opinion of Counsel and the other documents
      delivered pursuant to Sections 2.01 and 2.02, as applicable, in connection
      with the first authentication of Securities of such series. 

      If the Company
      shall establish pursuant to Section 2.03 that the Securities of a series
      or a portion thereof are to be issued in the form of one or more Registered
      Global Securities, then the Company shall execute and the Trustee shall
      authenticate and deliver one or more Registered Global Securities that
      (i) 

 11 

 shall represent and shall be denominated in an
    amount equal to the aggregate principal amount of all of the Securities of
    such series issued in such form and not yet cancelled, (ii) shall be registered
    in the name of the Depositary for such Registered Global Security or Securities
    or the nominee of such Depositary, (iii) shall be delivered by the Trustee
    to such Depositary or its custodian or pursuant to such Depositary’s
    instructions and (iv) shall bear a legend substantially to the following
    effect: “Unless and until it is exchanged in whole or in part for Securities
    in definitive registered form, this Security may not be transferred except
    as a whole by the Depositary to the nominee of the Depositary or 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 successor Depositary.”

      Section
        2.03. Amount Unlimited; Issuable in
        Series. The aggregate principal amount
        of Securities which may be authenticated and delivered under this Indenture
        is unlimited. 

      The Securities
      may be issued in one or more series and shall be subordinated to the Senior
      Indebtedness pursuant to the provisions of Article 11 hereof. There shall
      be established in or pursuant to Board Resolution or one or more indentures
      supplemental hereto, prior to the initial issuance of Securities of any
      series, subject to the last sentence of this Section 2.03,

      (a) the
    designation of the Securities of the series, which shall distinguish the
    Securities of the series from the Securities of all other series; 

      (b) any
    limit upon the aggregate principal amount of the Securities of the series
    that may be authenticated and delivered under this Indenture and any limitation
    on the ability of the Company to increase such aggregate principal amount
    after the initial issuance of the Securities of that series (except for Securities
    authenticated and delivered upon registration of transfer of, or in exchange
    for, or in lieu of, or upon redemption of, other Securities of the series
    pursuant hereto); 

      (c) the
    date or dates on which the principal of the Securities of the series is payable
    (which date or dates may be fixed or extendible); 

      (d) the
    rate or rates (which may be fixed or variable) per annum at which the Securities
    of the series shall bear interest, if any, the date or dates from which such
    interest shall accrue, on which such interest shall be payable and (in the
    case of Registered Securities) on which a record shall be taken for the determination
    of Holders to whom interest is payable and/or the method by which such rate
    or rates or date or dates shall be determined; 

 12 

      (e) if
    other than as provided in Section 4.02, the place or places where the principal
    of and any interest on Securities of the series shall be payable, any Registered
    Securities of the series may be surrendered for exchange, notices, demands
    to or upon the Company in respect of the Securities of the series and this
    Indenture may be served and notice to Holders may be published; 

      (f) the
    right, if any, of the Company to redeem Securities of the series, in whole

    upon which Securities of the series shall be redeemed, purchased or repaid,
    in whole or in part, pursuant to such obligation; 

      (h) if

    other than the coin or currency in which the Securities of the series are
    denominated, the coin or currency in which payment of the principal of or
    interest on the Securities of the series shall be payable or if the amount
    of payments of principal of and/or interest on the Securities of the series
    may be determined with reference to an index based on a coin or currency
    other than that in which the Securities of the series are denominated, the
    manner in which such amounts shall be determined; 

      (k) if
    other than the currency of the United States of America, the currency or
    currencies, including composite currencies, in which payment of the Principal
    of and interest on the Securities of the series shall be payable, and the
    manner in which any such currencies shall be valued against other currencies
    in which any other Securities shall be payable; 

      (l) whether
    the Securities of the series or any portion thereof will be issuable as Registered
    Securities (and if so, whether such Securities will be issuable as Registered
    Global Securities) or Unregistered Securities (with or without coupons) (and

    the offer, sale or delivery of Unregistered Securities or the payment 

 13

    and under what circumstances the Company will pay additional amounts on the
    Securities of the series held by a person who is not a U.S. person in respect
    of any tax, assessment or governmental charge withheld or deducted and, if

    than pay such additional amounts;

      (n) if
    the Securities of the series are to be issuable in definitive form (whether
    upon original issue or upon exchange of a temporary Security of such series)
    only upon receipt of certain certificates or other documents or satisfaction
    of other conditions, the form and terms of such certificates, documents or
    conditions;

    or the registrar or any other agents with respect to the Securities of the
    series;

      (p) provisions,
    if any, for the defeasance of the Securities of the series (including provisions
    permitting defeasance of less than all Securities of the series), which provisions
    may be in addition to, in substitution for, or in modification of (or any
    combination of the foregoing) the provisions of Article 8; 

      (q) if
    the Securities of the series are issuable in whole or in part as one or more
    Registered Global Securities or Unregistered Securities in global form, the
    identity of the Depositary or common Depositary for such Registered Global
    Security or Securities or Unregistered Securities in global form; 

      (r) any
    other Events of Default or covenants with respect to the Securities of the
    series; and

      (s) any
    other terms of the Securities of the series (which terms shall not be inconsistent
    with the provisions of this Indenture).

      All Securities
      of any one series and coupons, if any, appertaining thereto shall be substantially
      identical, except in the case of Registered Securities as to date and denomination,
      except in the case of any Periodic Offering and except as may otherwise
      be provided by or pursuant to the Board Resolution referred to above or
      as set forth in any such indenture supplemental hereto. 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 such Board Resolution or in any such indenture supplemental
      hereto and any forms and terms of Securities to be issued from time to
      time may be completed 

 14 

 and established from time to time prior to the
    issuance thereof by procedures described in such Board Resolution or supplemental
    indenture. 

      Unless otherwise
      expressly provided with respect to a series of Securities, the aggregate
      principal amount of a series of Securities may be increased and additional
      Securities of such series may be issued up to the maximum aggregate principal
      amount authorized with respect to such series as increased.      

      Section
        2.04. Denomination and Date of Securities;
        Payments of Interest. The Securities of
        each series shall be issuable as Registered Securities or Unregistered
        Securities in denominations established as contemplated by Section 2.03
        or, if not so established with respect to Securities of any series, in
        denominations of $1,000 and any integral multiple thereof. The Securities
        of each series shall be numbered, lettered or otherwise distinguished
        in such manner or in accordance with such plan as the Officers of the
        Company executing the same may determine, as evidenced by their execution
        thereof. 

      Unless otherwise
      specified with respect to a series of Securities, each Security shall be
      dated the date of its authentication. The Securities of each series shall
      bear interest, if any, from the date, and such interest and shall be payable
      on the dates, established as contemplated by Section 2.03. 

      The person
      in whose name any Registered Security of any series is registered at the
      close of business on any record date applicable to a particular series
      with respect to any interest payment date for such series shall be entitled
      to receive the interest, if any, payable on such interest payment date
      notwithstanding any transfer or exchange of such Registered Security subsequent
      to the record date and prior to such interest payment date, except if and
      to the extent the Company shall default in the payment of the interest
      due on such interest payment date for such series, in which case the provisions
      of Section 2.13 shall apply. The term “record date” as
      used with respect to any interest payment date (except a date for payment
      of defaulted interest) for the Securities of any series shall mean the
      date specified as such in the terms of the Registered Securities of such
      series established as contemplated by Section 2.03, or, if no such date
      is so established, the fifteenth day next preceding such interest payment
      date, whether or not such record date is a Business Day. 

      Section
        2.05. Registrar and Paying Agent; Agents
        Generally. The Company shall maintain an
        office or agency where Securities may be presented for registration,
        registration of transfer or for exchange (the “Registrar”)
        and an office or agency where Securities may be presented for payment
        (the “Paying Agent”), which shall be in the Borough
        of Manhattan, The City of New York or in Chicago, Illinois. The Company
        shall cause the Registrar to keep a register of the Registered Securities
        and of their registration, transfer and exchange (the 

 15 

 “Security
        Register”). The Company may have one
        or more additional Paying Agents or transfer agents with respect to any
        series. 

      The Company
      shall enter into an appropriate agency agreement with any Agent not a party
      to this Indenture. The agreement shall implement the provisions of this
      Indenture and the Trust Indenture Act that relate to such Agent. The Company
      shall give prompt written notice to the Trustee of the name and address
      of any Agent and any change in the name or address of an Agent. If the
      Company fails to maintain a Registrar or Paying Agent, the Trustee shall
      act as such. The Company may remove any Agent upon written notice to such
      Agent and the Trustee; provided that no such removal shall become
      effective until (i) the acceptance of an appointment by a successor Agent
      to such Agent as evidenced by an appropriate agency agreement entered into
      by the Company and such successor Agent and delivered to the Trustee or
      (ii) notification to the Trustee that the Trustee shall serve as such Agent
      until the appointment of a successor Agent in accordance with clause (i)
      of this proviso. The Company or any affiliate of the Company may act as
      Paying Agent or Registrar; provided that neither the Company nor
      an affiliate of the Company shall act as Paying Agent in connection with
      the defeasance of the Securities or the discharge of this Indenture under
      Article 8. 

      The Company
      initially appoints the Trustee as Registrar, Paying Agent and Authenticating
      Agent. If, at any time, the Trustee is not the Registrar, the Registrar
      shall make available to the Trustee ten days prior to each interest payment
      date and at such other times as the Trustee may reasonably request the
      names and addresses of the Holders as they appear in the Security Register. 

      Section
        2.06. Paying Agent to Hold Money in
        Trust. Not later than 10:00 a.m. New York
        City time on each due date or, in the case of Unregistered Securities,
        10:00 a.m. New York City time on the Business Day prior to the due date,
        of any Principal or interest on any Securities, the Company shall deposit
        with the Paying Agent money in immediately available funds sufficient
        to pay such Principal or interest. The Company shall require each Paying
        Agent other than the Trustee to agree in writing that such Paying Agent
        shall hold in trust for the benefit of the Holders of such Securities
        or the Trustee all money held by the Paying Agent for the payment of
        Principal of and interest on such Securities and shall promptly notify
        the Trustee of any default by the Company in making any such payment.
        The Company at any time may require a Paying Agent to pay all money held
        by it to the Trustee and account for any funds disbursed, and the Trustee
        may at any time during the continuance of any payment default, upon written
        request to a Paying Agent, require such Paying Agent to pay all money
        held by it to the Trustee and to account for any funds disbursed. Upon
        doing so, the Paying Agent shall have no further liability for the money
        so paid over to the Trustee. If the Company or any affiliate of the Company
        acts as Paying Agent, it 

 16 

 will, on or before each due date of any Principal
    of or interest on any Securities, segregate and hold in a separate trust
    fund for the benefit of the Holders thereof a sum of money sufficient to
    pay such Principal or interest so becoming due until such sum of money shall
    be paid to such Holders or otherwise disposed of as provided in this Indenture,
    and will promptly notify the Trustee in writing of its action or failure
    to act as required by this Section. 

      Section
        2.07. Transfer and Exchange. Unregistered
        Securities (except for any temporary global Unregistered Securities)
        and coupons (except for coupons attached to any temporary global Unregistered
        Securities) shall be transferable by delivery.

      At the option
      of the Holder thereof, Registered Securities of any series (other than
      a Registered Global Security, except as set forth below) may be exchanged
      for a Registered Security or Registered Securities of such series and tenor
      having authorized denominations and an equal aggregate principal amount,
      upon surrender of such Registered Securities to be exchanged at the agency
      of the Company that shall be maintained for such purpose in accordance
      with Section 2.05 and upon payment, if the Company shall so require, of
      the charges hereinafter provided. If the Securities of any series are issued
      in both registered and unregistered form, except as otherwise established
      pursuant to Section 2.03, at the option of the Holder thereof, Unregistered
      Securities of any series may be exchanged for Registered Securities of
      such series and tenor having authorized denominations and an equal aggregate
      principal amount, upon surrender of such Unregistered Securities to be
      exchanged at the agency of the Company that shall be maintained for such
      purpose in accordance with Section 4.02, with, in the case of Unregistered
      Securities that have coupons attached, all unmatured coupons and all matured
      coupons in default thereto appertaining, and upon payment, if the Company
      shall so require, of the charges hereinafter provided. At the option of
      the Holder thereof, if Unregistered Securities of any series, maturity
      date, interest rate and original issue date are issued in more than one
      authorized denomination, except as otherwise established pursuant to Section
      2.03, such Unregistered Securities may be exchanged for Unregistered Securities
      of such series and tenor having authorized denominations and an equal aggregate
      principal amount, upon surrender of such Unregistered Securities to be
      exchanged at the agency of the Company that shall be maintained for such
      purpose in accordance with Section 4.02, with, in the case of Unregistered
      Securities that have coupons attached, all unmatured coupons and all matured
      coupons in default thereto appertaining, and upon payment, if the Company
      shall so require, of the charges hereinafter provided. Registered Securities
      of any series may not be exchanged for Unregistered
      Securities of such series. Whenever any Securities are so surrendered for
      exchange, the Company shall execute, and the Trustee shall authenticate
      and deliver, the Securities which the Holder making the exchange is entitled
      to receive. 

 17 

      Upon surrender
      for registration of transfer of any Registered Security of a series at
      the agency of the Company that shall be maintained for that purpose in
      accordance with Section 2.05 and upon payment, if the Company shall so
      require, of the charges hereinafter provided, the Company shall execute,
      and the Trustee shall authenticate and deliver, in the name of the designated
      transferee or transferees, one or more new Registered Securities of the
      same series, of any authorized denominations and of like tenor and aggregate
      principal amount. 

      All Registered
      Securities presented for registration of transfer, exchange, redemption
      or payment shall be duly endorsed by, or be accompanied by a written instrument
      or instruments of transfer in form satisfactory to the Company and the
      Trustee duly executed by, the holder or his attorney duly authorized in
      writing. 

      The Company
      may require payment of a sum sufficient to cover any tax or other governmental
      charge that may be imposed in connection with any exchange or registration
      of transfer of Securities. No service charge shall be made for any such
      transaction. 

      Notwithstanding
      any other provision of this Section 2.07, unless and until it is exchanged
      in whole or in part for Securities in definitive registered form, a Registered
      Global Security representing all or a portion of the Securities of a series
      may not be transferred except as a whole by the Depositary for such series
      to a nominee of such Depositary or by a nominee of such Depositary to such
      Depositary or another nominee of such Depositary or by such Depositary
      or any such nominee to a successor Depositary for such series or a nominee
      of such successor Depositary.

      If at any
      time the Depositary for any Registered Global Securities of any series
      notifies the Company that it is unwilling or unable to continue as Depositary
      for such Registered Global Securities or if at any time the Depositary
      for such Registered Global Securities shall no longer be eligible under
      applicable law, the Company shall appoint a successor Depositary eligible
      under applicable law with respect to such Registered Global Securities.
      If a successor Depositary eligible under applicable law for such Registered
      Global Securities is not appointed by the Company within 90 days after
      the Company receives such notice or becomes aware of such ineligibility,
      the Company will execute, and the Trustee, upon receipt of the Company’s
      order for the authentication and delivery of definitive Registered Securities
      of such series and tenor, will authenticate and deliver Registered Securities
      of such series and tenor, in any authorized denominations, in an aggregate
      principal amount equal to the principal amount of such Registered Global
      Securities, in exchange for such Registered Global Securities.

 18 

      The Company
      may at any time and in its sole discretion and subject to the procedures
      of the Depositary determine that any Registered Global Securities of any
      series shall no longer be maintained in global form. In such event the
      Company will execute, and the Trustee, upon receipt of the Company’s
      order for the authentication and delivery of definitive Registered Securities
      of such series and tenor, will authenticate and deliver, Registered Securities
      of such series and tenor in any authorized denominations, in an aggregate
      principal amount equal to the principal amount of such Registered Global
      Securities, in exchange for such Registered Global Securities.

      Any time
      the Registered Securities of any series are not in the form of Registered
      Global Securities pursuant to the preceding two paragraphs, the Company
      agrees to supply the Trustee with a reasonable supply of certificated Registered
      Securities without the legend required by Section 2.02 and the Trustee
      agrees to hold such Registered Securities in safekeeping until authenticated
      and delivered pursuant to the terms of this Indenture.

      If established
      by the Company pursuant to Section 2.03 with respect to any Registered
      Global Security, the Depositary for such Registered Global Security may
      surrender such Registered Global Security in exchange in whole or in part
      for Registered Securities of the same series and tenor in definitive registered
      form on such terms as are acceptable to the Company and such Depositary.
      Thereupon, the Company shall execute, and the Trustee shall authenticate
      and deliver, without service charge,

        (a) to
      the Person specified by such Depositary new Registered Securities of the
      same series and tenor, of any authorized denominations as requested by
      such Person, in an aggregate principal amount equal to and in exchange
      for such Person’s beneficial interest in the Registered Global Security;
      and

        (b) to
      such Depositary a new Registered Global Security in a denomination equal
      to the difference, if any, between the principal amount of the surrendered
      Registered Global Security and the aggregate principal amount of Registered
      Securities authenticated and delivered pursuant to clause (a) above.

      Registered
      Securities issued in exchange for a Registered Global Security pursuant
      to this Section 2.07 shall be registered in such names and in such authorized
      denominations as the Depositary for such Registered Global Security, pursuant
      to instructions from its direct or indirect participants or otherwise,
      shall instruct the Trustee or an agent of the Company or the Trustee. The
      Trustee or such agent shall deliver such Securities to or as directed by
      the Persons in whose names such Securities are so registered. 

 19 

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

      Notwithstanding
      anything herein or in the forms or terms of any Securities to the contrary,
      none of the Company, the Trustee or any agent of the Company or the Trustee
      shall be required to exchange any Unregistered Security for a Registered
      Security if such exchange would result in adverse Federal income tax consequences
      to the Company (such as, for example, the inability of the Company to deduct
      from its income, as computed for Federal income tax purposes, the interest
      payable on the Unregistered Securities) under then applicable United States
      Federal income tax laws. The Trustee and any such agent shall be entitled
      to rely on an Officers’ Certificate or an Opinion of Counsel in determining
      such result.

      The Registrar
      shall not be required (i) to issue, authenticate, register the transfer
      of or exchange Securities of any series for a period of 15 days before
      a selection of such Securities to be redeemed or (ii) to register the transfer
      of or exchange any Security selected for redemption in whole or in part.

      Section
        2.08. Replacement Securities. If
        any mutilated Security or a Security with a mutilated coupon appertaining
        to it is surrendered to the Trustee, the Company shall execute and the
        Trustee shall authenticate and deliver, in exchange for such mutilated
        Security or in exchange for the Security to which a mutilated coupon
        appertains, a new Security of the same series and of like tenor and principal
        amount and bearing a number not contemporaneously outstanding, with coupons
        corresponding to the coupons, if any, appertaining to such mutilated
        Security or to the Security to which such mutilated coupon appertains. 

      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 or coupon
      and (ii) such security or indemnity as may be required by them to save
      each of them and any agent of any of them harmless, then, in the absence
      of notice to the Company or the Trustee that such Security or coupon has
      been acquired by a bona fide purchaser, the Company shall execute and the
      Trustee shall authenticate and deliver, in lieu of any such destroyed,
      lost or stolen Security or in exchange for the Security to which a destroyed,
      lost or stolen coupon appertains (with all appurtenant coupons not destroyed,
      lost or stolen), a new Security of the same series and of like tenor and
      principal amount and bearing a number not contemporaneously outstanding,
      with coupons corresponding to the coupons, if any, appertaining to such
      destroyed, lost or stolen Security or to the Security to which such destroyed,
      lost or stolen coupon appertains.

 20 

      In case any
      such mutilated, destroyed, lost or stolen Security or coupon has become
      or is about to become due and payable, the Company in its discretion may,
      instead of issuing a new Security, pay such Security or coupon (without
      surrender thereof except in the case of a mutilated Security or coupon)
      if the applicant for such payment shall furnish to the Company and the
      Trustee such security or indemnity as may be required by them to save each
      of them and any agent of any of them harmless, and in the case of destruction,
      loss or theft, evidence satisfactory to the Company and the Trustee and
      any agent of them of the destruction, loss or theft of such Security and
      the ownership thereof; provided, however, that the Principal of
      and any interest on Unregistered Securities shall, except as otherwise
      provided in Section 4.02, be payable only at an office or agency located
      outside the United States.

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

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

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

      Section
        2.09. Outstanding Securities. Securities
        outstanding at any time are all Securities that have been authenticated
        by the Trustee except for those cancelled by it, those delivered to it
        for cancellation, those described in this Section as not outstanding
        and those that have been defeased pursuant to Section 8.05.

      If a Security
      is replaced pursuant to Section 2.08, it ceases to be outstanding unless
      and until the Trustee and the Company receive proof satisfactory to them
      that the replaced Security is held by a holder in due course. 

      If the Paying
      Agent (other than the Company or an affiliate of the Company) holds on
      the maturity date or any redemption date or date for

 21 

 repurchase of the Securities money sufficient
    to pay Securities payable or to be redeemed or repurchased on that date,
    then on and after that date such Securities cease to be outstanding and interest
    on them shall cease to accrue.

      A Security
      does not cease to be outstanding because the Company or one of its affiliates
      holds such Security, provided, however, that, in determining whether
      the Holders of the requisite principal amount of the outstanding Securities
      have given any request, demand, authorization, direction, notice, consent
      or waiver hereunder, Securities owned by the Company or any affiliate of
      the Company shall be disregarded and deemed not to be outstanding, except
      that, in determining whether the Trustee shall be protected in relying
      upon any such request, demand, authorization, direction, notice, consent
      or waiver, only Securities as to which a Responsible Officer of the Trustee
      has received written notice to be so owned shall be so disregarded. Any
      Securities so owned which are pledged by the Company, or by any affiliate
      of the Company, as security for loans or other obligations, otherwise than
      to another such affiliate of the Company, shall be deemed to be outstanding,
      if the pledgee is entitled pursuant to the terms of its pledge agreement
      and is free to exercise in its or his discretion the right to vote such
      securities, uncontrolled by the Company or by any such affiliate. 

      Section
        2.10. Temporary Securities. Until
        definitive Securities of any series are ready for delivery, the Company
        may prepare and the Trustee shall authenticate temporary Securities of
        such series. Temporary Securities of any series shall be substantially
        in the form of definitive Securities of such series but may have insertions,
        substitutions, omissions and other variations determined to be appropriate
        by the Officers executing the temporary Securities, as evidenced by their
        execution of such temporary Securities. If temporary Securities of any
        series are issued, the Company will cause definitive Securities of such
        series to be prepared without unreasonable delay. After the preparation
        of definitive Securities of
        any series, the temporary Securities of such series shall be exchangeable
        for definitive Securities of such series and tenor upon surrender of
        such temporary Securities at the office or agency of the Company designated
        for such purpose pursuant to Section 4.02, without charge to the Holder.
        Upon surrender for cancellation of any one or more temporary Securities
        of any series the Company shall execute and the Trustee shall authenticate
        and deliver in exchange therefor a like principal amount of definitive
        Securities of such series and tenor and authorized denominations. Until
        so exchanged, the temporary Securities of any series shall be entitled
        to the same benefits under this Indenture as definitive Securities of
        such series.

      Section
        2.11. Cancellation. The
        Company at any time may deliver to the Trustee for cancellation any Securities
        previously authenticated and delivered hereunder which the Company may
        have acquired in any manner whatsoever, and may deliver to the Trustee
        for cancellation any Securities previously authenticated

 22 

 hereunder which the Company has not issued and
    sold. The Registrar, any transfer agent and the Paying Agent shall forward
    to the Trustee any Securities surrendered to them for transfer, exchange
    or payment. The Trustee shall cancel and dispose of in accordance with its
    customary procedures all Securities surrendered for transfer, exchange, payment
    or cancellation and shall deliver a certificate of disposition to the Company.
    The Company may not issue new Securities to replace Securities it has paid
    in full or delivered to the Trustee for cancellation.

      Section
        2.12. CUSIP Numbers. The
        Company in issuing the Securities may use “CUSIP” and “CINS” numbers
        (if then generally in use), and the Trustee shall use CUSIP numbers or
        CINS numbers, as the case may be, in notices of redemption or exchange
        as a convenience to Holders and no representation shall be made as to
        the correctness of such numbers either as printed on the Securities or
        as contained in any notice of redemption or exchange. 

      Section
        2.13. Defaulted Interest. If
        the Company defaults in a payment of interest on the Registered Securities,
        it shall pay, or shall deposit with the Paying Agent money in immediately
        available funds sufficient to pay, the defaulted interest plus (to the
        extent lawful) any interest payable on the defaulted interest (as may
        be specified in the terms thereof, established pursuant to Section 2.03)
        to the Persons who are Holders on a subsequent special record date, which
        shall mean the 15th day next preceding the date fixed by the Company
        for the payment of defaulted interest, whether or not such day is a Business
        Day. At least 15 days before such special record date, the Company shall
        mail to each Holder of such Registered Securities and to the Trustee
        a notice that states the special record date, the payment date and the
        amount of defaulted interest to be paid.

      Section
        2.14. Series May Include Tranches. A
        series of Securities may include one or more tranches (each a “tranche”)
        of Securities, including Securities issued in a Periodic Offering. The
        Securities of different tranches may have one or more different terms,
        including authentication dates and public offering prices, but all the
        Securities within each such tranche shall have identical terms, including
        authentication date and public offering price. Notwithstanding any other
        provision of this Indenture, with respect to Sections 2.02 (other than
        the fourth, sixth and seventh paragraphs thereof) through 2.04, 2.07,
        2.08, 2.10, 3.01 through 3.05, 4.02, 6.01 through 6.14, 8.01 through
        8.07, 9.02 and Section 10.07, if any series of Securities includes more
        than one tranche, all provisions of such sections applicable to any series
        of Securities shall be deemed equally applicable to each tranche of any
        series of Securities in the same manner as though originally designated
        a series unless otherwise provided with respect to such series or tranche
        pursuant to Section 2.03. In particular, and without limiting the scope
        of the next preceding sentence, any of the provisions of such sections
        which provide for or permit action to be taken with respect to a series
        of Securities shall also be 

 23 

 deemed to provide for and permit such action
    to be taken instead only with respect to Securities of one or more tranches
    within that series (and such provisions shall be deemed satisfied thereby),
    even if no comparable action is taken with respect to Securities in the remaining
    tranches of that series. 

ARTICLE 3 

  REDEMPTION

      Section
        3.01. Applicability of Article. The
        provisions of this Article shall be applicable to the Securities of any
        series which are redeemable before their maturity or to any sinking fund
        for the retirement of Securities of a series except as otherwise specified
        as contemplated by Section 2.03 for Securities of such series. 

      Section
        3.02. Notice of Redemption; Partial
        Redemptions. Notice of redemption to the
        Holders of Registered Securities of any series to be redeemed as a whole
        or in part at the option of the Company shall be given by mailing notice
        of such redemption by first class mail, postage prepaid, at least 30
        days and not more than 60 days prior to the date fixed for redemption
        to such Holders of Registered Securities of such series at their last
        addresses as they shall appear upon the registry books. Notice of redemption
        to the Holders of Unregistered Securities of any series to be redeemed
        as a whole or in part who have filed their names and addresses with the
        Trustee pursuant to Section 313(c)(2) of the Trust Indenture Act, shall
        be given by mailing notice of such redemption, by first class mail, postage
        prepaid, at least 30 days and not more than 60 days prior to the date
        fixed for redemption, to such Holders at such addresses as were so furnished
        to the Trustee (and, in the case of any such notice given by the Company,
        the Trustee shall make such information available to the Company for
        such purpose). Notice of redemption to all other Holders of Unregistered
        Securities of any series to be redeemed as a whole or in part shall be
        published in an Authorized Newspaper in The City of New York or with
        respect to any Security the interest on which is based on the offered
        quotations in the interbank Eurodollar market for dollar deposits in
        an Authorized Newspaper in London, in each case, once in each of three
        successive calendar weeks, the first publication to be not less than
        30 days nor more than 60 days prior to the date fixed for redemption.
        Any notice which is mailed or published in the manner herein provided
        shall be conclusively presumed to have been duly given, whether or not
        the Holder receives the notice. Failure to give 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. 

 24 

      The notice
      of redemption to each such Holder shall specify the principal amount of
      each Security of such series held by such Holder to be redeemed, the CUSIP
      numbers of the Securities to be redeemed, the date fixed for redemption,
      the redemption price, or if not then ascertainable, the manner of calculation
      thereof, the place or places of payment, that payment will be made upon
      presentation and surrender of such Securities and, in the case of Securities
      with coupons attached thereto, of all coupons appertaining thereto maturing
      after the date fixed for redemption, that such redemption is pursuant to
      the mandatory or optional sinking fund, or both, if such be the case, that
      interest accrued to the date fixed for redemption will be paid as specified
      in such notice and that on and after said date interest thereon or on the
      portions thereof to be redeemed will cease to accrue. 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 such series and tenor in
      principal amount equal to the unredeemed portion thereof will be issued. 

      The notice
      of redemption of Securities of any series to be redeemed at the option
      of the Company shall be given by the Company or, at the Company’s
      request, by the Trustee in the name and at the expense of the Company. 

      On or before
      10:00 a.m. New York City time on the redemption date or, in the case of
      Unregistered Securities, on or before 10:00 a.m. New York City time on
      the Business Day prior to the redemption date specified in the notice of
      redemption given as provided in this Section, the Company will deposit
      with the Trustee or with one or more Paying Agents (or, if the Company
      is acting as its own Paying Agent, set aside, segregate and hold in trust
      as provided in Section 2.06) an amount of money sufficient to redeem on
      the redemption date all the Securities of such series so called for redemption
      at the appropriate redemption price, together with accrued interest to
      the date fixed for redemption. If all of the outstanding Securities of
      a series are to be redeemed, the Company will deliver to the Trustee at
      least 10 days prior to the last date on which notice of redemption may
      be given to Holders pursuant to the first paragraph of this Section 3.02
      (or such shorter period as shall be acceptable to the Trustee) an Officers’ Certificate
      stating that all such Securities are to be redeemed. If less than all the
      outstanding Securities of a series are to be redeemed, the Company will
      deliver to the Trustee at least 15 days prior to the last date on which
      notice of redemption may be given to Holders pursuant to the first paragraph
      of this Section 3.02 (or such shorter period as shall be acceptable to
      the Trustee) an Officers’ Certificate stating the aggregate principal
      amount of such Securities to be redeemed. In the case of any redemption
      of Securities (a) prior to the expiration of any restriction on such redemption
      provided in the terms of such Securities or elsewhere in this Indenture,
      or (b) pursuant to an election of the Company which is subject to a condition
      specified in the terms of such Securities or elsewhere in this Indenture,
      the 

 25 

 Company shall deliver to the Trustee, prior to
    the giving of any notice of redemption to Holders pursuant to this Section,
    an Officers’ Certificate evidencing compliance with such restriction
    or condition.

      If less than
      all the Securities of a series are to be redeemed, the Trustee shall select,
      pro rata, by lot or in such manner as it shall deem appropriate and fair,
      Securities of such series to be redeemed in whole or in part. Securities
      may be redeemed in part in principal amounts equal to authorized denominations
      for Securities of such series. The Trustee shall promptly notify the Company
      in writing of the Securities of such series selected for redemption and,
      in the case of any Securities of such series selected for partial redemption,
      the principal amount thereof to be redeemed. For all purposes of this Indenture,
      unless the context otherwise requires, all provisions relating to the redemption
      of Securities shall relate, in the case of any Security redeemed or to
      be redeemed only in part, to the portion of the principal amount of such
      Security which has been or is to be redeemed. 

      Section
        3.03. Payment Of Securities Called For
        Redemption. If notice of redemption has
        been given as above provided, the Securities or portions of Securities
        specified in such notice shall become due and payable on the date and
        at the place stated in such notice at the applicable redemption price,
        together with interest accrued to the date fixed for redemption, and
        on and after such date (unless the Company shall default in the payment
        of such Securities at the redemption price, together with interest accrued
        to such date) interest on the Securities or portions of Securities so
        called for redemption shall cease to accrue, and the unmatured coupons,
        if any, appertaining thereto shall be void and, except as provided in
        Sections 7.12 and 8.02, such Securities shall cease from and after the
        date fixed for redemption to be entitled to any benefit under this Indenture,
        and the Holders thereof shall have no right in respect of such Securities
        except the right to receive the redemption price thereof and unpaid interest
        to the date fixed for redemption. On presentation and surrender of such
        Securities at a place of payment specified in said notice, together with
        all coupons, if any, appertaining thereto maturing after the date fixed
        for redemption, said Securities or the specified portions thereof shall
        be paid and redeemed by the Company at the applicable redemption price,
        together with interest accrued thereon to the date fixed for redemption;
        provided that payment of interest becoming due on or prior to the date
        fixed for redemption shall be payable in the case of Securities with
        coupons attached thereto, to the Holders of the coupons for such interest
        upon surrender thereof, and in the case of Registered Securities, to
        the Holders of such Registered Securities registered as such on the relevant
        record date subject to the terms and provisions of Sections 2.04 and
        2.13 hereof.

      If any Security
      called for redemption shall not be so paid upon surrender thereof for redemption,
      the principal shall, until paid or duly provided for, bear 

 26 

 interest from the date fixed for redemption at
    the rate of interest or Yield to Maturity (in the case of an Original Issue
    Discount Security) borne by such Security. 

      If any Security
      with coupons attached thereto is surrendered for redemption and is not
      accompanied by all appurtenant coupons maturing after the date fixed for
      redemption, the surrender of such missing coupon or coupons may be waived
      by the Company and the Trustee, if there be furnished to each of them such
      security or indemnity as they may require to save each of them harmless. 

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

      Section
        3.04. Exclusion of Certain Securities
        from Eligibility for Selection for Redemption. Securities
        shall be excluded from eligibility for selection for redemption if they
        are identified by registration and certificate number in a written statement
        signed by an authorized officer of the Company and delivered to the Trustee
        at least 40 days prior to the last date on which notice of redemption
        may be given as being owned of record and beneficially by, and not pledged
        or hypothecated by, either (a) the Company or (b) an entity specifically
        identified in such written statement as directly or indirectly controlling
        or controlled by or under direct or indirect common control with the
        Company.

      Section
        3.05. Mandatory and Optional Sinking
        Funds. 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 the Securities of any series is herein referred to as an “optional
        sinking fund payment”. The date on which a sinking fund payment
        is to be made is herein referred to as the “sinking fund payment
        date”. 

      In lieu of
      making all or any part of any mandatory sinking fund payment with respect
      to any series of Securities in cash, the Company may at its option (a)
      deliver to the Trustee Securities of such series theretofore purchased
      or otherwise acquired (except through a mandatory sinking fund payment)
      by the Company or receive credit for Securities of such series (not previously
      so credited) theretofore purchased or otherwise acquired (except as aforesaid)
      by the Company and delivered to the Trustee for cancellation pursuant to
      Section 2.11, (b) receive credit for optional sinking fund payments (not
      previously so credited) made pursuant to this Section, or (c) receive credit
      for Securities of such series (not 

 27 

 previously so credited) redeemed by the Company
    at the option of the Company pursuant to the terms of such Securities or
    through any optional sinking fund payment. Securities so delivered or credited
    shall be received or credited by the Trustee at the sinking fund redemption
    price specified in such Securities. 

      On or before
      the sixtieth day next preceding each sinking fund payment date for any
      series, or such shorter period as shall be acceptable to the Trustee, the
      Company will deliver to the Trustee an Officers’ Certificate (a) specifying
      the portion of the mandatory sinking fund payment to be satisfied by payment
      of cash and the portion to be satisfied by credit of specified Securities
      of such series and the basis for such credit, (b) stating that none of
      the specified Securities of such series has theretofore been so credited,
      (c) stating that no defaults in the payment of interest or Events of Default
      with respect to such series have occurred (which have not been waived or
      cured) and are continuing and (d) stating whether or not the Company intends
      to exercise its right to make an optional sinking fund payment with respect
      to such series and, if so, specifying the amount of such optional sinking
      fund payment which the Company intends to pay on or before the next succeeding
      sinking fund payment date. Any Securities of such series to be credited
      and required to be delivered to the Trustee in order for the Company to
      be entitled to credit therefor as aforesaid which have not theretofore
      been delivered to the Trustee shall be delivered for cancellation pursuant
      to Section 2.11 to the Trustee with such Officers’ Certificate (or
      reasonably promptly thereafter if acceptable to the Trustee). Such Officers’
  Certificate shall be irrevocable and upon its receipt by the Trustee the Company
  shall become unconditionally obligated to make all the cash payments or delivery
  of Securities therein referred to, if any, on or before the next succeeding
  sinking fund payment date. Failure of the Company, on or before any such sixtieth
  day, to deliver such Officer’s Certificate and Securities specified in
  this paragraph, if any, shall not constitute a default but shall constitute,
  on and as of such date, the irrevocable election of the Company (i) that the
  mandatory sinking fund payment for such series due on the next succeeding sinking
  fund payment date shall be paid entirely in cash without the option to deliver
  or credit Securities of such series in respect thereof and (ii) that the Company
  will make no optional sinking fund payment with respect to such series as provided
  in this Section. 

      If the sinking
      fund payment or payments (mandatory or optional or both) to be made in
      cash on the next succeeding sinking fund payment date plus any unused balance
      of any preceding sinking fund payments made in cash shall exceed $50,000
      (or a lesser sum if the Company shall so request with respect to the Securities
      of any series), such cash shall be applied on the next succeeding sinking
      fund payment date to the redemption of Securities of such series at the
      sinking fund redemption price thereof together with accrued interest thereon
      to the date fixed for redemption. If such amount shall be $50,000 (or such
      lesser sum) or less and the Company makes no such request then it shall
      be carried over 

 28 

 until a sum in excess of $50,000 (or such lesser
    sum) is available. The Trustee shall select, in the manner provided in Section
    3.02, for redemption on such sinking fund payment date a sufficient principal
    amount of Securities of such series to absorb said cash, as nearly as may
    be, and shall (if requested in writing by the Company) inform the Company
    of the serial numbers of the Securities of such series (or portions thereof)
    so selected. Securities shall be excluded from eligibility for redemption
    under this Section if they are identified by registration and certificate
    number in an Officers’ Certificate delivered to the Trustee at least
    60 days prior to the sinking fund payment date as being owned of record and
    beneficially by, and not pledged or hypothecated by either (a) the Company
    or (b) an entity specifically identified in such Officers’ Certificate
    as directly or indirectly controlling or controlled by or under direct or
    indirect common control with the Company. The Trustee, in the name and at
    the expense of the Company (or the Company, if it shall so request the Trustee
    in writing) shall cause notice of redemption of the Securities of such series
    to be given in substantially the manner provided in Section 3.02 (and with
    the effect provided in Section 3.03) for the redemption of Securities of
    such series in part at the option of the Company. The amount of any sinking
    fund payments not so applied or allocated to the redemption of Securities
    of such series shall be added to the next cash sinking fund payment for such
    series and, together with such payment, shall be applied in accordance with
    the provisions of this Section. Any and all sinking fund moneys held on the
    stated maturity date of the Securities of any particular series (or earlier,
    if such maturity is accelerated), which are not held for the payment or redemption
    of particular Securities of such series shall be applied, together with other
    moneys, if necessary, sufficient for the purpose, to the payment of the Principal
    of, and interest on, the Securities of such series at maturity. 

      On or before
      10:00 a.m. New York City time on each sinking fund payment date or, in
      the case of Unregistered Securities, 10:00 a.m. New York City time on the
      Business Day prior to the sinking fund payment date, the Company shall
      pay to the Trustee in cash or shall otherwise provide for the payment of
      all interest accrued to the date fixed for redemption on Securities to
      be redeemed on the next following sinking fund payment date. 

      The Trustee
      shall not redeem or cause to be redeemed any Securities of a series with
      sinking fund moneys or mail any notice of redemption of Securities of such
      series by operation of the sinking fund during the continuance of a Default
      in payment of interest on such Securities or of any Event of Default except
      that, where the mailing of notice of redemption of any Securities shall
      theretofore have been made, the Trustee shall redeem or cause to be redeemed
      such Securities, provided that it shall have received from the Company
      a sum sufficient for such redemption. 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 the sinking
      fund, shall, during the continuance of such 

 29 

 Default or Event of Default, be deemed to have
    been collected under Article 6 and held for the payment of all such Securities.
    In case such Event of Default shall have been waived as provided in Section
    6.04 or the Default cured on or before the sixtieth day preceding the sinking
    fund payment date in any year, such moneys shall thereafter be applied on
    the next succeeding sinking fund payment date in accordance with this Section
    to the redemption of such Securities. 

ARTICLE 4

  COVENANTS

      Section
        4.01. Payment of Securities. The
        Company shall pay the Principal of and interest on the Securities on
        the dates and in the manner provided in the Securities and this Indenture.
        The interest on Securities with coupons attached (together with any additional
        amounts payable pursuant to the terms of such Securities) shall be payable
        only upon presentation and surrender of the several coupons for such
        interest installments as are evidenced thereby as they severally mature.
        The interest on any temporary Unregistered Securities (together with
        any additional amounts payable pursuant to the terms of such Securities)
        shall be paid, as to the installments of interest evidenced by coupons
        attached thereto, if any, only upon presentation and surrender thereof,
        and, as to the other installments of interest, if any, only upon presentation
        of such Unregistered Securities for notation thereon of the payment of
        such interest. The interest on Registered Securities (together with any
        additional amounts payable pursuant to the terms of such Securities)
        shall be payable only to the Holders thereof (subject to Section 2.04)
        and at the option of the Company may be paid by mailing checks for such
        interest payable to or upon the written order of such Holders at their
        last addresses as they appear on the Security Register of the Company.

      Notwithstanding
      any provisions of this Indenture and the Securities of any series to the
      contrary, if the Company and a Holder of any Registered Security so agree,
      payments of interest on, and any portion of the Principal of, such Holder’s
      Registered Security (other than interest payable at maturity or on any
      redemption or repayment date or the final payment of Principal on such
      Security) shall be made by the Paying Agent, upon receipt from the Company
      of immediately available funds by 11:00 A.M., New York City time (or such
      other time as may be agreed to between the Company and the Paying Agent),
      directly to the Holder of such Security (by Federal funds wire transfer
      or otherwise) if the Holder has delivered written instructions to the Trustee
      15 days prior to such payment date requesting that such payment will be
      so made and designating the bank account to which such payments shall be
      so made and in the case of payments of Principal, surrenders the same to
      the Trustee in exchange for a Security or Securities aggregating the same
      principal amount as the unredeemed principal amount of the Securities surrendered.
      The Trustee shall be entitled to rely on the last instruction 

 30 

 delivered by the Holder pursuant to this Section
    4.01 unless a new instruction is delivered 15 days prior to a payment date.
    The Company will indemnify and hold each of the Trustee and any Paying Agent
    harmless against any loss, liability or expense (including attorneys’ fees)
    resulting from any act or omission to act on the part of the Company or any
    such Holder in connection with any such agreement or from making any payment
    in accordance with any such agreement.

      The Company
      shall pay interest on overdue Principal, and interest on overdue installments
      of interest, to the extent lawful, at the rate per annum specified in the
      Securities. 

      Section
        4.02. Maintenance of Office or Agency. The
        Company will maintain in the Borough of Manhattan, The City of New York,
        or Chicago, Illinois an office or agency where Securities may be surrendered
        for registration of transfer or exchange or for presentation for payment
        and where notices and demands to or upon the Company in respect of the
        Securities and this Indenture may be served. The Company hereby initially
        designates the Corporate Trust Office of the Trustee, located in Chicago,
        Illinois, as such office or agency of the Company. The Company will give
        prompt written notice to the Trustee of the location, and any change
        in the location, of such office or agency. If at any time the Company
        shall fail to maintain any such required office or agency or shall fail
        to furnish the Trustee with the address thereof, such presentations,
        surrenders, notices and demands may be made or served at the address
        of the Trustee set forth in Section 10.02. 

      The Company
      will maintain one or more agencies in a city or cities located outside
      the United States (including any city in which such an agency is required
      to be maintained under the rules of any stock exchange on which the Securities
      of any series are listed) where the Unregistered Securities, if any, of
      each series and coupons, if any, appertaining thereto may be presented
      for payment. No payment on any Unregistered Security or coupon will be
      made upon presentation of such Unregistered Security or coupon at an agency
      of the Company within the United States nor will any payment be made by
      transfer to an account in, or by mail to an address in, the United States
      unless, pursuant to applicable United States laws and regulations then
      in effect, such payment can be made without adverse tax consequences to
      the Company. Notwithstanding the foregoing, if full payment in United States
      Dollars (“Dollars”) at each agency maintained by the Company
      outside the United States for payment on such Unregistered Securities or
      coupons appertaining thereto is illegal or effectively precluded by exchange
      controls or other similar restrictions, payments in Dollars of Unregistered
      Securities of any series and coupons appertaining thereto which are payable
      in Dollars may be made at an agency of the Company maintained in the Borough
      of Manhattan, The City of New York, or Chicago, Illinois. 

 31 

      The Company
      may also from time to time designate one or more other offices or agencies
      where the Securities of any series may be presented or surrendered for
      any or all such purposes and may from time to time rescind such designations;
      provided that no such designation or rescission shall in any manner relieve
      the Company of its obligation to maintain an office or agency in the Borough
      of Manhattan, The City of New York, or Chicago, Illinois for such purposes.
      The Company will give prompt written notice to the Trustee of any such
      designation or rescission and of any change in the location of any such
      other office or agency. 

      Section
        4.03. Securityholders’ Lists. The
        Company will furnish or cause to be furnished to the Trustee a list in
        such form as the Trustee may reasonably require of the names and addresses
        of the holders of the Securities pursuant to Section 312 of the Trust
        Indenture Act of 1939 (a) semi-annually not more than 15 days after each
        record date for the payment of semi-annual interest on the Securities,
        as hereinabove specified, as of such record date, and (b) at such other
        times as the Trustee may request in writing, within thirty days after
        receipt by the Company of any such request as of a date not more than
        15 days prior to the time such information is furnished.

      Section
        4.04. Certificate to Trustee. The
        Company will furnish to the Trustee annually, on or before a date not
        more than four months after the end of its fiscal year (which, on the
        date hereof, is a calendar year), a brief certificate (which need not
        contain the statements required by Section 10.04) from its principal
        executive, financial or accounting officer as to his or her knowledge
        of the compliance of the Company with all conditions and covenants under
        this Indenture (such compliance to be determined without regard to any
        period of grace or requirement of notice provided under this Indenture)
        which certificate shall comply with the requirements of the Trust Indenture
        Act. 

      Section
        4.05. Reports by the Company. The
        Company covenants to file with the Trustee, within 15 days after the
        Company is required to file the same with the Commission, copies of the
        annual reports and of the information, documents, and other reports which
        the Company may be required to file with the Commission pursuant to Section
        13 or Section 15(d) of the Exchange Act. 

      Section
        4.06. Additional Amounts. If the
        Securities of a series provide for the payment of additional amounts,
        at least 10 days prior to the first interest payment date with respect
        to that series of Securities and at least 10 days prior to each date
        of payment of Principal of or interest on the Securities of that series
        if there has been a change with respect to the matters set forth in the
        below-mentioned Officers’ Certificate, the Company shall furnish
        to the Trustee and the principal paying agent, if other than the Trustee,
        an Officers’ Certificate instructing the Trustee and such paying
        agent whether such payment of Principal 

 32 

 of or interest on the Securities of that series
    shall be made to Holders of the Securities of that series without withholding
    or deduction for or on account of any tax, assessment or other governmental
    charge described in the Securities of that series. If any such withholding
    or deduction shall be required, then such Officers’ Certificate shall
    specify by country the amount, if any, required to be withheld or deducted
    on such payments to such Holders and shall certify the fact that additional
    amounts will be payable and the amounts so payable to each Holder, and the
    Company shall pay to the Trustee or such paying agent the additional amounts
    required to be paid by this Section. The Company covenants to indemnify the
    Trustee and any paying agent for, and to hold them harmless against, any
    loss, liability or expense reasonably incurred without negligence or bad
    faith on their part arising out of or in connection with actions taken or
    omitted by any of them in reliance on any Officers’ Certificate furnished
    pursuant to this Section. 

      Whenever
      in this Indenture there is mentioned, in any context, the payment of the
      Principal of or interest or any other amounts on, or in respect of, any
      Security of any series, such mention shall be deemed to include mention
      of the payment of additional amounts provided by the terms of such series
      established hereby or pursuant hereto to the extent that, in such context,
      additional amounts are, were or would be payable in respect thereof pursuant
      to such terms, and express mention of the payment of additional amounts
      (if applicable) in any provision hereof shall not be construed as excluding
      the payment of additional amounts in those provisions hereof where such
      express mention is not made. 

ARTICLE 5 

  SUCCESSOR CORPORATION

      Section
        5.01. When Company May Merge, Etc. The
        Company shall not consolidate with, merge with or into, or sell, convey,
        transfer, lease or otherwise dispose of all or substantially all of its
        property and assets (in one transaction or a series of related transactions)
        to, any Person unless either (x) the Company shall be the continuing
        Person or (y) the Person (if other than the Company) formed by such consolidation
        or into which the Company is merged or to which properties and assets
        of the Company shall be sold, conveyed, transferred or leased shall be
        a corporation organized and validly existing under the laws of the United
        States of America or any jurisdiction thereof and shall expressly assume,
        by a supplemental indenture, executed and delivered to the Trustee, all
        of the obligations of the Company on all of the Securities and under
        this Indenture and the Company in the case of clauses (x) and (y) shall
        have delivered to the Trustee (A) an Opinion of Counsel stating that
        such consolidation, merger or sale, conveyance, transfer or lease and
        such supplemental indenture (if any) complies with this provision and
        that all conditions precedent provided for herein relating to such transaction
        have 

 33 

 been complied with and that such supplemental
    indenture (if any) constitutes the legal, valid and binding obligation of
    the Company and such successor enforceable against such entity in accordance
    with its terms, subject to customary exceptions and (B) an Officers’ Certificate
    to the effect that immediately after giving effect to such transaction, no
    Default shall have occurred and be continuing. 

      Section
        5.02. Successor Substituted. Upon
        any consolidation or merger, or any sale, conveyance, transfer, lease
        or other disposition of all or substantially all of the property and
        assets of the Company in accordance with Section 5.01 of this Indenture,
        the successor Person formed by such consolidation or into which the Company
        is merged or to which such sale, conveyance, transfer, lease or other
        disposition is made shall succeed to, and be substituted for, and may
        exercise every right and power of, the Company under this Indenture with
        the same effect as if such successor Person had been named as the Company
        herein and thereafter the predecessor Person, except in the case of a
        lease, shall be relieved of all obligations and covenants under this
        Indenture and the Securities. 

ARTICLE 6 

  DEFAULT AND REMEDIES

      Section
        6.01. Events of Default. An “Event
        of Default” shall occur with respect to the Securities of any
        series if: 

      (a) the
    Company defaults in the payment of the Principal of any Security of such
    series when the same becomes due and payable at maturity, upon acceleration,
    redemption or mandatory repurchase, including as a sinking fund installment,
    or otherwise; 

      (b) the
    Company defaults in the payment of interest on any Security of such series
    when the same becomes due and payable, and such default continues for a period
    of 30 days; 

      (c) the
    Company defaults in the performance of or breaches any other covenant or
    agreement of the Company in this Indenture with respect to any Security of
    such series or in the Securities of such series and such default or breach
    continues for a period of 30 consecutive days after written notice to the
    Company by the Trustee or to the Company and the Trustee by the Holders of
    25% or more in aggregate principal amount of the Securities of all series
    affected thereby specifying such default or breach and requiring it to be
    remedied and stating that such notice is a “Notice of Default” hereunder; 

 34 

      (d) 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 similar official) of the Company or for any substantial part of its property
    or ordering the winding up or liquidation of its affairs, and such decree
    or order shall remain unstayed and in effect for a period of 60 consecutive
    days; 

      (e) the
    Company (i) commences a voluntary case under any applicable bankruptcy, insolvency
    or other similar law now or hereafter in effect, or consents to the entry
    of an order for relief in an involuntary case under any such law, (ii) consents
    to the appointment of or taking possession by a receiver, liquidator, assignee,
    custodian, trustee, sequestrator or similar official of the Company or for
    all or substantially all of the property and assets of the Company or (iii)
    effects any general assignment for the benefit of creditors; or 

      (f) any
    other Event of Default established pursuant to Section 2.03 with respect
    to the Securities of such series occurs. 

      Section
        6.02. Acceleration. (a)
        If an Event of Default other than as described in clauses (d) or (e)
        of Section 6.01 with respect to the Securities of any series then outstanding
        occurs and is continuing, then, and in each and every such case, except
        for any series of Securities the principal of which shall have already
        become due and payable, either the Trustee or the Holders of not less
        than 25% in aggregate principal amount of the Securities of any such
        series then outstanding hereunder (each such series treated as a separate
        class) by notice in writing to the Company (and to the Trustee if given
        by Securityholders), may declare the entire principal (or, if the Securities
        of any such series are Original Issue Discount Securities, such portion
        of the principal amount as may be specified in the terms of such series
        established pursuant to Section 2.03) of all Securities of such series,
        and the interest accrued thereon, if any, to be due and payable immediately,
        and upon any such declaration the same shall become immediately due and
        payable. 

      (b) If
    an Event of Default described in clause (d) or (e) of Section 6.01 occurs
    and is continuing, then the principal amount (or, if any Securities are Original
    Issue Discount Securities, such portion of the principal as may be specified
    in the terms thereof established pursuant to Section 2.03) of all the Securities
    then outstanding and interest accrued thereon, if any, shall be and become
    immediately due and payable, without any notice or other action by any Holder
    or the Trustee, to the full extent permitted by applicable law. 

      The foregoing
      provisions, however, are subject to the condition that if, at any time
      after the principal (or, if the Securities are Original Issue Discount
      Securities, such portion of the principal as may be specified in the terms
      thereof 

 35 

 established pursuant to Section 2.03) of the
    Securities of any series (or of all the Securities, as the case may be) shall
    have been so declared or become 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 installments of interest upon
    all the Securities of each such series (or of all the Securities, as the
    case may be) and the principal of any and all Securities of each such series
    (or of all the Securities, as the case may be) which shall have become due
    otherwise than by acceleration (with interest upon such principal and, to
    the extent that payment of such interest is enforceable under applicable
    law, on overdue installments of interest, at the same rate as the rate of
    interest or Yield to Maturity (in the case of Original Issue Discount Securities)
    specified in the Securities of each such series to the date of such payment
    or deposit) and such amount as shall be sufficient to cover all amounts owing
    the Trustee under Section 7.07, and if any and all Events of Default under
    the Indenture, other than the non-payment of the principal of Securities
    which shall have become due by acceleration, shall have been cured, waived
    or otherwise remedied as provided herein, then and in every such case the
    Holders of a majority in aggregate principal amount of all the then outstanding
    Securities of all such series that have been accelerated (voting as a single
    class), by written notice to the Company and to the Trustee, may waive all
    defaults with respect to all such series (or with respect to all the 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. 

      For all purposes
      under this Indenture, if a portion of the principal of any Original Issue
      Discount Securities shall have been accelerated and declared or become
      due and payable pursuant to the provisions hereof, then, from and after
      such declaration, unless such declaration has been rescinded and annulled,
      the principal amount of such Original Issue Discount Securities shall be
      deemed, for all purposes hereunder, to be such portion of the principal
      thereof as shall be due and payable as a result of such acceleration, and
      payment of such portion of the principal thereof as shall be due and payable
      as a result of such acceleration, together with interest, if any, thereon
      and all other amounts owing thereunder, shall constitute payment in full
      of such Original Issue Discount Securities. 

      Section
        6.03. Other Remedies. If
        a payment default or an Event of Default with respect to the Securities
        of any series occurs and is continuing, the Trustee may pursue, in its
        own name or as trustee of an express trust, any available remedy by proceeding
        at law or in equity to collect the payment of Principal of and interest
        on the Securities of such series or to enforce the performance of any
        provision of the Securities of such series or this Indenture. 

 36 

      The Trustee
      may maintain a proceeding even if it does not possess any of the Securities
      or does not produce any of them in the proceeding. 

      Section
        6.04. Waiver of Past Defaults. Subject
        to Sections 6.02, 6.07 and 9.02, the Holders of at least a majority in
        principal amount (or, if the Securities are Original Issue Discount Securities,
        such portion of the principal as is then accelerable under Section 6.02)
        of the outstanding Securities of all series affected (voting as a single
        class), by notice to the Trustee, may waive an existing Default or Event
        of Default with respect to the Securities of such series and its consequences,
        except a Default in the payment of Principal of or interest on any Security
        as specified in clauses (a) or (b) of Section 6.01 or in respect of a
        covenant or provision of this Indenture which cannot be modified or amended
        without the consent of the Holder of each outstanding Security affected.
        Upon any such waiver, such Default shall cease to exist, and any Event
        of Default with respect to the Securities of such series arising therefrom
        shall be deemed to have been cured, for every purpose of this Indenture;
        but no such waiver shall extend to any subsequent or other Default or
        Event of Default or impair any right consequent thereto. 

      Section
        6.05. Control by Majority. Subject
        to Sections 7.01 and 7.02(e), the Holders of at least a majority in aggregate
        principal amount (or, if any Securities are Original Issue Discount Securities,
        such portion of the principal as is then accelerable under Section 6.02)
        of the outstanding Securities of all series affected (voting as a single
        class) may 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
        by this Indenture; provided, that the Trustee may refuse to follow any
        direction that conflicts with law or this Indenture, that may involve
        the Trustee in personal liability or that the Trustee determines in good
        faith may be unduly prejudicial to the rights of Holders not joining
        in the giving of such direction; and provided further, that the Trustee
        may take any other action it deems proper that is not inconsistent with
        any directions received from Holders of Securities pursuant to this Section
        6.05. 

      Section
        6.06. Limitation on Suits. No
        Holder of any Security of any series may institute any proceeding, judicial
        or otherwise, with respect to this Indenture or the Securities of such
        series, or for the appointment of a receiver or trustee, or for any other
        remedy hereunder, unless: 

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

 37 

        (b) the
      Holders of at least 25% in aggregate principal amount of outstanding Securities
      of all such series affected shall have made written request to the Trustee
      to institute proceedings in respect of such Event of Default in its own
      name as Trustee hereunder; 

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

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

        (e) during
      such 60-day period, the Holders of a majority in aggregate principal amount
      of the outstanding Securities of all such affected series have not given
      the Trustee a direction that is inconsistent with such written request. 

      A Holder
      may not use this Indenture to prejudice the rights of another Holder or
      to obtain a preference or priority over such other Holder. 

      Section
        6.07. Rights of Holders to Receive Payment. Notwithstanding
        any other provision of this Indenture, the right of any Holder of a Security
        to receive payment of Principal of or interest, if any, on such Holder’s
        Security on or after the respective due dates expressed on such Security,
        or to bring 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
        6.08. Collection Suit by Trustee. If
        an Event of Default with respect to the Securities of any series in payment
        of Principal or interest specified in clause (a) or (b) of Section 6.01
        occurs and is continuing, the Trustee may recover judgment in its own
        name and as trustee of an express trust against the Company for the whole
        amount (or such portion thereof as specified in the terms established
        pursuant to Section 2.03 of Original Issue Discount Securities) of Principal
        of, and accrued interest remaining unpaid on, together with interest
        on overdue Principal of, and, to the extent that payment of such interest
        is lawful, interest on overdue installments of interest on, the Securities
        of such series, in each case at the rate or Yield to Maturity (in the
        case of Original Issue Discount Securities) specified in such Securities,
        and such further amount as shall be sufficient to cover all amounts owing
        the Trustee under Section 7.07. 

      Section
        6.09. Trustee May File Proofs of Claim. The
        Trustee may 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
        (including any claim for amounts due the Trustee under Section 7.07)
        and the Holders allowed in any 

38 

 judicial proceedings relative to the
    Company (or any other obligor on the Securities), its creditors or its property
    and shall be entitled and empowered to collect and receive any moneys, securities
    or other property payable or deliverable upon conversion or exchange of the
    Securities or upon any such claims and to distribute the same, and any custodian,
    receiver, assignee, trustee, liquidator, sequestrator or other similar official
    in any such judicial proceeding is hereby authorized by each Holder to make
    such payments to the Trustee and, in the event that the Trustee shall consent
    to the making of such payments directly to the Holders, to pay to the Trustee
    any amount due to it under Section 7.07. Nothing herein contained shall be
    deemed to empower the Trustee to authorize or consent to, or accept or adopt
    on behalf of any Holder, any plan of reorganization, arrangement, adjustment
    or composition affecting the Securities or the rights of any Holder thereof,
    or to authorize the Trustee to vote in respect of the claim of any Holder
    in any such proceeding. 

      Section
      6.10. Application of Proceeds. Any
      moneys collected by the Trustee pursuant to this Article in respect of
      the Securities of any series shall be applied in the following order at
      the date or dates fixed by the Trustee and, in case of the distribution
      of such moneys on account of Principal or interest, upon presentation of
      the several Securities and coupons appertaining to such Securities in respect
      of which moneys have been collected and noting thereon the payment, or
      issuing Securities of such series and tenor in reduced principal amounts
      in exchange for the presented Securities of such series and tenor if only
      partially paid, or upon surrender thereof if fully paid: 

        FIRST:
      To the payment of all amounts due the Trustee under Section 7.07 applicable
      to the Securities of such series in respect of which moneys have been collected; 

        SECOND:
      Subject to Article 11, in case the principal of the Securities of such
      series in respect of which moneys have been collected shall not have become
      and be then due and payable, to the payment of interest on the Securities
      of such series in default in the order of the maturity of the installments
      of such interest, with interest (to the extent that such interest has been
      collected by the Trustee) upon the overdue installments of interest at
      the same rate as the rate of interest or Yield to Maturity (in the case
      of Original Issue Discount Securities) specified in such Securities, such
      payments to be made ratably to the persons entitled thereto, without discrimination
      or preference; 

        THIRD:
      Subject to Article 11, in case the principal of the Securities of such
      series in respect of which moneys have been collected shall have become
      and shall be then due and payable, to the payment of the whole amount then
      owing and unpaid upon all the Securities of such 

 39 

   series for Principal and interest,
      with interest upon the overdue Principal, and (to the extent that such
      interest has been collected by the Trustee) upon overdue installments of
      interest at the same rate as the rate of interest or Yield to Maturity
      (in the case of Original Issue Discount Securities) specified in the Securities
      of such series; and in case such moneys shall be insufficient to pay in
      full the whole amount so due and unpaid upon the Securities of such series,
      then to the payment of such Principal and interest or Yield to Maturity,
      without preference or priority of Principal over interest or Yield to Maturity,
      or of interest or Yield to Maturity over Principal, or of any installment
      of interest over any other installment of interest, or of any Security
      of such series over any other Security of such series, ratably to the aggregate
      of such Principal and accrued and unpaid interest or Yield to Maturity;
      and 

        FOURTH:
      To the payment of the remainder, if any, to the Company or any other person
      lawfully entitled thereto. 

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

      Section
      6.12. Undertaking
      for Costs. In any suit for the enforcement
      of any right or remedy under this Indenture or in any suit against the
      Trustee for any action taken or omitted by it as Trustee, in either case
      in respect to the Securities of any series, a court may require any party
      litigant in such suit (other than the Trustee) to file an undertaking to
      pay the costs of the suit, and the court may assess reasonable costs, including
      reasonable attorneys’ fees, against any party litigant (other than
      the Trustee) in the suit having due regard to the merits and good faith
      of the claims or defenses made by the party litigant. This Section 6.12
      does not apply to a suit by a Holder pursuant to Section 6.07, a suit instituted
      by the Trustee or a suit by Holders of more than 10% in principal amount
      of the outstanding Securities of such series.

      Section
      6.13. Rights and Remedies Cumulative. Except
      as otherwise provided with respect to the replacement or payment of mutilated,
      destroyed, lost or wrongfully taken Securities in Section 2.08, 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 

 40 

 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
      6.14. Delay or Omission not Waiver. No
      delay or omission of the Trustee or of any Holder 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 6 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. 

 ARTICLE 7 

  TRUSTEE 

      Section
      7.01. General. The
      duties and responsibilities of the Trustee shall be as provided by the
      Trust Indenture Act and as set forth herein. Notwithstanding
      the foregoing, 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, unless it receives indemnity satisfactory
      to it against any loss, liability or expense. 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 Article 7. 

      Section
      7.02. Certain Rights of Trustee. Subject
      to Trust Indenture Act Sections 315(a) through (d): 

        (a) the
      Trustee may rely and shall be protected in acting or refraining from acting
      upon any resolution, certificate, Officers’ Certificate, Opinion of
      Counsel (or both), statement, instrument, opinion, report, notice, request,
      direction, consent, order, bond, debenture, note, other evidence of indebtedness
      or other paper or document believed by it to be genuine and to have been
      signed or presented by the proper person or persons. The Trustee need not
      investigate any fact or matter stated in the document, but the Trustee,
      in its discretion, may make such further inquiry or investigation into
      such facts or matters as it may see fit; 

        (b) before
      the Trustee acts or refrains from acting, it may require an Officers’ Certificate
      and/or an Opinion of Counsel, which shall conform to Section 10.04 and
      shall cover such other matters as the Trustee 

41 

   may reasonably request. The Trustee
      shall not be liable for any action it takes or omits to take in good faith
      in reliance on such certificate or opinion. Subject to Sections 7.01 and
      7.02, whenever in the administration of the trusts of this Indenture the
      Trustee shall deem it necessary or desirable that a matter be proved or
      established prior to taking or suffering or omitting any action hereunder,
      such matter (unless other evidence in respect thereof be herein specifically
      prescribed) may, in the absence of negligence or bad faith on the part
      of the Trustee, be deemed to be conclusively proved and established by
      an Officers’ Certificate delivered to the Trustee, and such certificate,
      in the absence of negligence or bad faith on the part of the Trustee, shall
      be full warrant to the Trustee for any action taken, suffered or omitted
      by it under the provisions of this Indenture upon the faith thereof; 

        (c) the
      Trustee may act through its attorneys and agents not regularly in its employ
      and shall not be responsible for the misconduct or negligence of any agent
      or attorney appointed with due care; 

        (d) any
      request, direction, order or demand of the Company mentioned herein shall
      be sufficiently evidenced by an Officers’ Certificate (unless other
      evidence in respect thereof be herein specifically prescribed); and any
      Board Resolution may be evidenced to the Trustee by a copy thereof certified
      by the Secretary or an Assistant Secretary of the Company; 

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

        (f) the
      Trustee shall not be liable for any action it takes or omits to take in
      good faith that it believes to be authorized or within its rights or powers
      or for any action it takes or omits to take in accordance with the direction
      of the Holders in accordance with Section 6.05 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;

        (g) the
      Trustee may consult with counsel and the written advice of such counsel
      or any Opinion of Counsel shall be full and complete authorization and
      protection in respect of any action taken, 

 42 

   suffered or omitted by it hereunder
      in good faith and in reliance thereon; and 

        (h) prior
      to the occurrence of an Event of Default hereunder and after the curing
      or waiving of all Events of Default, the Trustee shall not be bound to
      make any investigation into the facts or matters stated in any resolution,
      certificate, Officers’ Certificate, Opinion of Counsel, Board Resolution,
      statement, instrument, opinion, report, notice, request, consent, order,
      approval, appraisal, bond, debenture, note, coupon, security, or other
      paper or document unless requested in writing so to do by the Holders of
      not less than a majority in aggregate principal amount of the Securities
      of all series affected then outstanding; provided that, if the payment
      within a reasonable time to the Trustee of the costs, expenses or liabilities
      likely to be incurred by it in the making of such investigation is, in
      the opinion of the Trustee, not reasonably assured to the Trustee by the
      security afforded to it by the terms of this Indenture, the Trustee may
      require reasonable indemnity against such expenses or liabilities as a
      condition to proceeding. 

      Section
      7.03. Individual Rights of Trustee. The
      Trustee, in its individual or any other capacity, may become the owner
      or pledgee of Securities and may otherwise deal with the Company or its
      Affiliates with the same rights it would have if it were not the Trustee.
      Any Agent may do the same with like rights. However, the Trustee is subject
      to Trust Indenture Act Sections 310(b) and 311. For purposes of Trust Indenture
      Act Section 311(b)(4) and (6), the following terms shall mean: 

      (a) “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; and 

      (b) “self-liquidating
      paper” means any draft, bill
      of 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. 

 43 

      Section
      7.04. Trustee's Disclaimer. The
      recitals contained herein and in the Securities (except the Trustee’s
      certificate of authentication) shall be taken as statements of the Company
      and not of the Trustee and the Trustee assumes no responsibility for the
      correctness of the same. Neither the Trustee nor any of its agents (a)
      makes any representation as to the validity or adequacy of this Indenture
      or the Securities and (b) shall be accountable for the Company’s use
      or application of the proceeds from the Securities. 

      Section
      7.05. Notice of Default. If
      any Default with respect to the Securities of any series occurs and is
      continuing and if such Default is known to the actual knowledge of a Responsible
      Officer with the Corporate Trust Department of the Trustee, the Trustee
      shall give to each Holder of Securities of such series notice of such Default
      within 90 days after it occurs (a) if any Unregistered Securities of such
      series are then outstanding, to the Holders thereof, by publication at
      least once in an Authorized Newspaper in the Borough of Manhattan, The
      City of New York and at least once in an Authorized Newspaper in London
      and (b) to all Holders of Securities of such series in the manner and to
      the extent provided in Section 313(c) of the Trust Indenture Act, unless
      such Default shall have been cured or waived before the mailing or publication
      of such notice; provided, however, that, except in the case of a Default
      in the payment of the Principal of or interest on any Security, the Trustee
      shall be protected in withholding such notice if the Trustee in good faith
      determines that the withholding of such notice is in the interests of the
      Holders. 

      Section
      7.06. Reports by Trustee to Holders. The
      Trustee shall transmit to Holders such reports concerning the Trustee and
      its actions under this Indenture as may be required pursuant to the Trust
      Indenture Act at the times and in the manner provided pursuant thereto.
      If required by Section 313(a) of the Trust Indenture Act, the Trustee shall,
      within 60 days after each May 15 following the date of this Indenture,
      deliver to Holders a brief report, dated as of such May 15, which complies
      with the provisions of such Section 313(a). 

      A copy
    of each such report shall, at the time of such transmission to Holders, be
    filed by the Trustee with each stock exchange upon which any Securities are
    listed, with the Commission and with the Company. The Company will promptly
    notify the Trustee when any Securities are listed on any stock exchange. 

      Section
      7.07. Compensation and Indemnity. The
      Company shall pay to the Trustee such compensation as shall be agreed upon
      in writing from time to time for its services. The compensation of the
      Trustee shall not be limited by any law on compensation of a Trustee of
      an express trust. The Company shall reimburse the Trustee and any predecessor
      Trustee upon request for all reasonable out-of-pocket expenses, disbursements
      and advances incurred or made by the 

 44 

 Trustee or such predecessor Trustee.
    Such expenses shall include the reasonable compensation and expenses of the
    Trustee’s or such predecessor Trustee’s agents, counsel and other
    persons not regularly in their employ. 

      The
    Company shall indemnify the Trustee and any predecessor Trustee for, and
    hold them harmless against, any loss or liability or expense incurred by
    them without negligence or bad faith on their part arising out of or in connection
    with the acceptance or administration of this Indenture and the Securities
    or the issuance of the Securities or of series thereof or the trusts hereunder
    and the performance of duties under this Indenture and the Securities, including
    the costs and expenses of defending themselves against or investigating any
    claim or liability and of complying with any process served upon them or
    any of their officers in connection with the exercise or performance of any
    of their powers or duties under this Indenture and the Securities. 

      To secure
    the Company’s payment obligations in this Section 7.07, the Trustee
    shall have a lien prior to the Securities on all money or property held or
    collected by the Trustee, in its capacity as Trustee, except money or property
    held in trust to pay Principal of, and interest on particular Securities. 

      The
    obligations of the Company under this Section to compensate and indemnify
    the Trustee and each predecessor Trustee and to pay or reimburse the Trustee
    and each predecessor Trustee for expenses, disbursements and advances shall
    constitute additional indebtedness hereunder and shall survive the satisfaction
    and discharge of this Indenture or the rejection or termination of this Indenture
    under bankruptcy law. Such additional indebtedness shall be a senior claim
    to that of the Securities upon all property and funds held or collected by
    the Trustee as such, except funds held in trust for the benefit of the Holders
    of particular Securities or coupons, and the Securities are hereby subordinated
    to such senior claim. Without prejudice to any other rights available to
    the Trustee under applicable law, if the Trustee renders services and incurs
    expenses following an Event of Default under Section 6.01(d) or Section 6.01(e)
    hereof, the parties hereto and the holders by their acceptance of the Securities
    hereby agree that such expenses are intended to constitute expenses of administration
    under any bankruptcy law. 

      Section
      7.08. Replacement of Trustee. A
      resignation or removal of the Trustee as Trustee with respect to the Securities
      of any series and appointment of a successor Trustee as Trustee with respect
      to the Securities of any series shall become effective only upon the successor
      Trustee’s acceptance of appointment as provided in this Section 7.08. 

      The
    Trustee may resign as Trustee with respect to the Securities of any series
    at any time by so notifying the Company in writing. The Holders of a 

 45 

 majority in principal amount of the
    outstanding Securities of any series may remove the Trustee as Trustee with
    respect to the Securities of such series by so notifying the Trustee in writing
    and may appoint a successor Trustee with respect thereto with the consent
    of the Company. The Company may remove the Trustee as Trustee with respect
    to the Securities of any series if: (i) the Trustee is no longer eligible
    under Section 7.11 of this Indenture; (ii) the Trustee is adjudged a bankrupt
    or insolvent; (iii) a receiver or other public officer takes charge of the
    Trustee or its property; or (iv) the Trustee becomes incapable of acting. 

      If the
    Trustee resigns or is removed as Trustee with respect to the Securities of
    any series, or if a vacancy exists in the office of Trustee with respect
    to the Securities of any series for any reason, the Company shall promptly
    appoint a successor Trustee with respect thereto. Within one year after the
    successor Trustee takes office, the Holders of a majority in principal amount
    of the outstanding Securities of such series may appoint a successor Trustee
    in respect of such Securities to replace the successor Trustee appointed
    by the Company. If the successor Trustee with respect to the Securities of
    any series does not deliver its written acceptance required by Section 7.09
    within 30 days after the retiring Trustee resigns or is removed, the retiring
    Trustee, the Company or the Holders of a majority in principal amount of
    the outstanding Securities of such series may petition any court of competent
    jurisdiction for the appointment of a successor Trustee with respect thereto. 

      The
    Company shall give notice of any resignation and any removal of the Trustee
    with respect to the Securities of any series and each appointment of a successor
    Trustee in respect of the Securities of such series to all Holders of Securities
    of such series. Each notice shall include the name of the successor Trustee
    and the address of its Corporate Trust Office. 

      Notwithstanding
    replacement of the Trustee with respect to the Securities of any series pursuant
    to this Section 7.08 and Section 7.09, the Company’s obligations under
    Section 7.07 shall continue for the benefit of the retiring Trustee. 

      Section
      7.09. Acceptance
      of Appointment by Successor. In case
      of the appointment hereunder of a successor Trustee with respect to all
      Securities, every such successor Trustee so appointed shall execute, acknowledge
      and deliver to the Company and to the retiring Trustee an instrument accepting
      such appointment, and thereupon the resignation or removal of the retiring
      Trustee shall become effective and such successor Trustee, without any
      further act, deed or conveyance, shall become vested with all the rights,
      powers, trusts and duties of the retiring Trustee; but, on the request
      of the Company or the successor Trustee, such retiring Trustee shall, upon
      payment of its charges and subject to the lien provided for in Section
      7.07, execute and deliver an instrument transferring to such successor
      Trustee all the rights, powers and trusts of the retiring Trustee and shall 

 46 

 duly assign, transfer and deliver
    to such successor Trustee all property and money held by such retiring Trustee
    hereunder. 

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

      Upon
    request of any such successor Trustee, the Company shall execute any and
    all instruments for more fully and certainly vesting in and confirming to
    such successor Trustee all such rights, powers and trusts referred to in
    the first or second preceding paragraph, as the case may be. 

      No successor
    Trustee shall accept its appointment unless at the time of such acceptance
    such successor Trustee shall be eligible under this Article and qualified
    under Section 310(b) of the Trust Indenture Act. 

      Section
      7.10. Successor Trustee By Merger,
      Etc. If the Trustee consolidates with,
      merges or converts into, or transfers all or substantially all of 

 47 

 its corporate trust business to, another
    corporation or national banking association, the resulting, surviving or
    transferee corporation or national banking association without any further
    act shall be the successor Trustee with the same effect as if the successor
    Trustee had been named as the Trustee herein. 

      Section
      7.11. Eligibility. This
      Indenture shall always have a Trustee who satisfies the requirements of
      Trust Indenture Act Section 310(a). The Trustee shall have a combined capital
      and surplus of at least $25,000,000 as set forth in its most recent
      published annual report of condition. 

      Section
      7.12. Money Held in Trust. 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 and except for money held in trust under Article 8 of this
      Indenture. 

 ARTICLE 8 

  SATISFACTION AND DISCHARGE
  OF INDENTURE; UNCLAIMED MONEYS 

      Section
      8.01. Satisfaction and Discharge
      of Indenture. If at any time (a) the
      Company shall have paid or caused to be paid the Principal of and interest
      on all the Securities of any series outstanding hereunder (other than Securities
      of such series which have been destroyed, lost or stolen and which have
      been replaced or paid as provided in Section 2.08) as and when the same
      shall have become due and payable, or (b) the Company shall have delivered
      to the Trustee for cancellation all Securities of any series theretofore
      authenticated (other than any Securities of such series which shall have
      been destroyed, lost or stolen and which shall have been replaced or paid
      as provided in Section 2.08) or (c) (i) all the securities of such series
      not theretofore delivered to the Trustee for cancellation shall have become
      due and payable, or are by their terms to become due and payable within
      one year or are to be called for redemption within one year under arrangements
      satisfactory to the Trustee for the giving of notice of redemption, and
      (ii) the Company shall have irrevocably deposited or caused to be deposited
      with the Trustee as trust funds the entire amount in cash (other than moneys
      repaid by the Trustee or any paying agent to the Company in accordance
      with Section 8.04) or U.S. Government Obligations, maturing as to principal
      and interest in such amounts and at such times as will insure (without
      consideration of the reinvestment of such interest) the availability of
      cash, or a combination thereof, sufficient to pay at maturity or upon redemption
      all Securities of such series (other than any Securities of such series
      which shall have been destroyed, lost or stolen and which shall have been
      replaced or paid as provided in Section 2.08) not theretofore delivered
      to the Trustee for cancellation, including principal and interest due or
      to become due on or prior to such date of maturity or 

 48 

 redemption as the case may be, and
    if, in any such case, the Company is not prohibited from making payments
    in respect of the Securities by Article 11 hereof and shall also pay or cause
    to be paid all other sums payable hereunder by the Company with respect to
    Securities of such series, then this Indenture shall cease to be of further
    effect with respect to Securities of such series (except as to (i) rights
    of registration of transfer and exchange of securities of such series, and
    the Company’s right of optional redemption, if any, (ii) substitution
    of mutilated, defaced, destroyed, lost or stolen Securities, (iii) rights
    of holders to receive payments of principal thereof and interest thereon,
    upon the original stated due dates therefor (but not upon acceleration) and
    remaining rights of the holders to receive mandatory sinking fund payments,
    if any, (iv) the rights, obligations and immunities of the Trustee hereunder
    and (v) the rights of the Securityholders of such series as beneficiaries
    hereof with respect to the property so deposited with the Trustee payable
    to all or any of them), and the Trustee, on demand of the Company accompanied
    by an Officers’ Certificate and an Opinion of Counsel and at the cost
    and expense of the Company, shall execute proper instruments acknowledging
    such satisfaction of and discharging this Indenture with respect to such
    series; provided, that the rights of Holders of the Securities to receive
    amounts in respect of Principal of and interest on the Securities held by
    them shall not be delayed longer than required by then-applicable mandatory
    rules or policies of any securities exchange upon which the Securities are
    listed. The Company agrees to reimburse the Trustee for any costs or expenses
    thereafter reasonably and properly incurred and to compensate the Trustee
    for any services thereafter reasonably and properly rendered by the Trustee
    in connection with this Indenture or the Securities of such series. 

      Section
      8.02. Application by Trustee of
      Funds Deposited for Payment of Securities. Subject
      to Section 8.04, all moneys (including U.S. Government Obligations and
      the proceeds thereof) deposited with the Trustee pursuant to Section 8.01,
      Section 8.05 or Section 8.06 shall be held in trust and applied by it to
      the payment, either directly or through any paying agent to the Holders
      of the particular Securities of such series for the payment or redemption
      of which such moneys have been deposited with the Trustee, of all sums
      due and to become due thereon for Principal and interest; but such money
      need not be segregated from other funds except to the extent required by
      law. Funds and U.S. Government Obligations held in trust under Section
      8.01, 8.05 or 8.06 shall not be subject to the claims of the holders of
      Senior Indebtedness under Article 11. 

      Section
      8.03. Repayment of Moneys Held
      by Paying Agent. In connection with
      the satisfaction and discharge of this Indenture with respect to Securities
      of any series, all moneys then held by any paying agent under the provisions
      of this Indenture with respect to such series of Securities shall, upon
      demand of the Company, be repaid to it or paid to the Trustee and thereupon
      such paying agent shall be released from all further liability with respect
      to such moneys. 

 49 

      Section
      8.04. Return of Moneys Held by
      Trustee and Paying Agent Unclaimed for Two Years. Any
      moneys deposited with or paid to the Trustee or any paying agent for the
      payment of the Principal of or interest on any Security of any series and
      not applied but remaining unclaimed for two years after the date upon which
      such Principal or interest shall have become due and payable, shall, upon
      the written request of the Company and unless otherwise required by mandatory
      provisions of applicable escheat or abandoned or unclaimed property law,
      be repaid to the Company by the Trustee for such series or such paying
      agent, and the Holder of the Security of such series shall, unless otherwise
      required by mandatory provisions of applicable escheat or abandoned or
      unclaimed property laws, thereafter look only to the Company for any payment
      which such Holder may be entitled to collect, and all liability of the
      Trustee or any paying agent with respect to such moneys shall thereupon
      cease. 

      Section
      8.05. Defeasance and Discharge
      of Indenture. The Company shall be
      deemed to have paid and shall be discharged from any and all obligations
      in respect of the Securities of any series, on the 123rd day after the
      deposit referred to in clause (i) hereof has been made, and the provisions
      of this Indenture shall no longer be in effect with respect to the Securities
      of such series (and the Trustee, at the expense of the Company, shall execute
      proper instruments acknowledging the same), except as to: (a) rights of
      registration of transfer and exchange, and the Company’s right of
      optional redemption, (b) substitution of apparently mutilated, defaced,
      destroyed, lost or stolen Securities, (c) rights of holders to receive
      payments of principal thereof and interest thereon, upon the original stated
      due dates therefor (but not upon acceleration), (d) the rights, obligations
      and immunities of the Trustee hereunder and (e) the rights of the Securityholders
      of such series as beneficiaries hereof with respect to the property so
      deposited with the Trustee payable to all or any of them; provided that
      the following conditions shall have been satisfied: 

        (i) with
      reference to this provision the Company has deposited or caused to be irrevocably
      deposited with the Trustee (or another qualifying trustee satisfying the
      requirements of Section 7.11) as trust funds in trust, specifically pledged
      as security for, and dedicated solely to, the benefit of the Holders of
      the Securities of such series, (A) money in an amount, or (B) U.S. Government
      Obligations which through the payment of interest and principal in respect
      thereof in accordance with their terms will provide not later than one
      day before the due date of any payment referred to in subclause (x) or
      (y) of this clause (i) money in an amount, or (C) a combination thereof,
      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 without consideration of the reinvestment
      of such interest and after payment of all federal, state and local taxes
      or other charges and assessments in respect 

 50 

   thereof payable by the Trustee (x)
      the principal of, premium, if any, and each installment of interest on
      the outstanding Securities of such series on the due dates thereof and
      (y) any mandatory sinking fund payments or analogous payments applicable
      to the Securities of such series on the day on which such payments are
      due and payable in accordance with the terms of Securities of such series
      and the Indenture with respect to the Securities of such series; 

        (ii) the
      Company has delivered to the Trustee (A) either (x) an Opinion of Counsel
      to the effect that Holders of Securities of such series will not recognize
      income, gain or loss for federal income tax purposes as a result of the
      Company’s exercise of its option under this Section 8.05 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
      and discharge had not occurred, which Opinion of Counsel must be based
      upon a ruling of the Internal Revenue Service to the same effect or a change
      in applicable federal income tax law or related treasury regulations after
      the date of this Indenture or (y) a ruling directed to the Trustee received
      from the Internal Revenue Service to the same effect as the aforementioned
      Opinion of Counsel and (B) an Opinion of Counsel to the effect that the
      creation of the defeasance trust does not violate the Investment Company
      Act of 1940 and after the passage of 123 days following the deposit, the
      trust fund will not be subject to the effect of Section 547 of the U.S.
      Bankruptcy Code or Section 15 of the New York Debtor and Creditor Law;

        (iii) immediately
      after giving effect to such deposit on a pro forma basis, no Event of Default,
      or event that after the giving of notice or lapse of time or both would
      become an Event of Default, shall have occurred and be continuing on the
      date of such deposit or during the period ending on the 123rd day after
      the date of such deposit, and such deposit shall not result in a breach
      or violation of, or constitute a default under, any other agreement or
      instrument to which the Company is a party or by which the Company is bound;

        (iv) if
      at such time the Securities of such series are listed on a national securities
      exchange, the Company has delivered to the Trustee an Opinion of Counsel
      to the effect that the Securities of such series will not be delisted as
      a result of such deposit, defeasance and discharge;

        (v) the
      Company shall have delivered to the Trustee an Officers’ Certificate
      and an Opinion of Counsel, each stating that all conditions precedent to
      the defeasance and discharge under this Section have been complied with;
      and 

 51 

        (vi) if
      the Securities of such series are to be redeemed prior to the final maturity
      thereof (other than from mandatory sinking fund payments or analogous payments),
      notice of such redemption shall have been duly given pursuant to this Indenture
      or provision therefor satisfactory to the Trustee shall have been made. 

      Section
      8.06. Defeasance of Certain Obligations. The
      Company may omit to comply with any term, provision or condition set forth
      in, and this Indenture will no longer be in effect with respect to, any
      covenant established pursuant to Section 2.03(r) and clause (c) (with respect
      to any covenants established pursuant to Section 2.03(r)) and clause (f)
      of Section 6.01 shall be deemed not to be an Event of Default, if

      (a) with
    reference to this Section 8.06, the Company has deposited or caused to be
    irrevocably deposited with the Trustee (or another qualifying trustee satisfying
    the requirements of Section 7.11) as trust funds in trust, specifically pledged
    as security for, and dedicated solely to, the benefit of the Holders of the
    Securities of such series and the Indenture with respect to the Securities
    of such series, (i) money in an amount or (ii) U.S. Government Obligations
    which through the payment of interest and principal in respect thereof in
    accordance with their terms will provide not later than one day before the
    due dates thereof or earlier redemption (irrevocably provided for under agreements
    satisfactory to the Trustee), as the case may be, of any payment referred
    to in subclause (x) or (y) of this clause (a) money in an amount, or (iii)
    a combination thereof, 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 without consideration
    of the reinvestment of such interest and after payment of all federal, state
    and local taxes or other charges and assessments in respect thereof payable
    by the Trustee (x) the principal of, premium, if any, and each installment
    of interest on the outstanding Securities on the due date thereof or earlier
    redemption (irrevocably provided for under arrangements satisfactory to the
    Trustee), as the case may be, and (y) any mandatory sinking fund payments
    or analogous payments applicable to the Securities of such series and the
    Indenture with respect to the Securities of such series on the day on which
    such payments are due and payable in accordance with the terms of the Indenture
    and of Securities of such series and the Indenture with respect to the Securities
    of such series; 

      (b) the
    Company has delivered to the Trustee (i) an Opinion of Counsel to the effect
    that Holders of Securities of such series will not recognize income, gain
    or loss for federal income tax purposes as a result of the Company’s
    exercise of its option under this Section 8.06 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 and defeasance had not occurred
    and (ii) an Opinion 

 52

 of Counsel to the effect that the
    creation of the defeasance trust does not violate the Investment Company
    Act of 1940 and after the passage of 123 days following the deposit, the
    trust fund will not be subject to the effect of Section 547 of the U.S. Bankruptcy
    Code or Section 15 of the New York Debtor and Creditor Law;

      (c) immediately
    after giving effect to such deposit on a pro forma basis, no Event of Default,
    or event that after the giving of notice or lapse of time or both would become
    an Event of Default, shall have occurred and be continuing on the date of
    such deposit or during the period ending on the 123rd day after the date
    of such deposit, and such deposit shall not result in a breach or violation
    of, or constitute a default under, any other agreement or instrument to which
    the Company is a party or by which the Company is bound;

      (d) if
    at such time the Securities of such series are listed on a national securities
    exchange, the Company has delivered to the Trustee an Opinion of Counsel
    to the effect that the Securities of such series will not be delisted as
    a result of such deposit, defeasance and discharge; and 

      (e) the
    Company shall have delivered to the Trustee an Officers’ Certificate
    and an Opinion of Counsel, each stating that all conditions precedent to
    the defeasance under this Section have been complied with. 

      Section
      8.07. Reinstatement. If
      the Trustee or paying agent is unable to apply any monies or U.S. Government
      Obligations in accordance with Article 8 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 this Article until
      such time as the Trustee or paying agent is permitted to apply all such
      monies or U.S. Government Obligations in accordance with Article 8; provided,
      however, that if the Company has made
      any payment of Principal of or interest on any Securities because of the
      reinstatement of its obligations, the Company shall be subrogated to the
      rights of the Holders of such Securities to receive such payment from the
      monies or U.S. Government Obligations held by the Trustee or paying agent. 

      Section
      8.08. Indemnity. The
      Company shall pay and indemnify the Trustee (or other qualifying trustee,
      collectively for purposes of this Section 8.08 and Section 8.02, the “Trustee”)
      against any tax, fee or other charge, imposed on or assessed against the
      U.S. Government Obligations deposited pursuant to Section 8.01, 8.05 or
      8.06 or the principal or interest received in respect thereof other than
      any such tax, fee or other charge which by law is for the account of the
      Holders of the Securities and any coupons appertaining thereto. 

 53 

      Section
      8.09. Excess
      Funds. Anything in this Article 8
      to the contrary notwithstanding, the Trustee shall deliver or pay to the
      Company from time to time upon request of the Company, any money or U.S.
      Government Obligations (or other property and any proceeds therefrom) held
      by it as provided in Section 8.01, 8.05 or 8.06 which, in the opinion of
      a nationally recognized firm of Independent Public Accountants expressed
      in a written certification thereof delivered to the Trustee, are in excess
      of the amount thereof which would then be required to be deposited to effect
      a discharge or defeasance, as applicable, in accordance with this Article
      8. 

      Section
      8.10. Qualifying
      Trustee. Any trustee appointed pursuant
      to Section 8.05 or 8.06 for the purpose of holding money or U.S. Government
      Obligations deposited pursuant to such Sections shall be appointed under
      an agreement in form acceptable to the Trustee and shall provide to the
      Trustee a certificate, upon which certificate the Trustee shall be entitled
      to conclusively rely, that all conditions precedent provided for herein
      to the related defeasance have been complied with. In no event shall the
      Trustee be liable for any acts or omissions of said trustee 

 ARTICLE 9 

  AMENDMENTS, SUPPLEMENTS
  AND WAIVERS 

      Section
      9.01. Without Consent of Holders. The
      Company and the Trustee may amend or supplement this Indenture or the Securities
      of any series without notice to or the consent of any Holder: 

        (a) to
      cure any ambiguity, defect or inconsistency in this Indenture; provided that
      such amendments or supplements shall not materially and adversely affect
      the interests of the Holders; 

         (b) to
      comply with Article 5; 

        (c) to
      comply with any requirements of the Commission in connection with the qualification
      of this Indenture under the Trust Indenture Act; 

        (d) to
      evidence and provide for the acceptance of appointment hereunder with respect
      to the Securities of any or all series by a successor Trustee and to add
      to or change any of the provisions of this Indenture as shall be necessary
      to provide for or facilitate the administration of the trusts hereunder
      by more than one Trustee, pursuant to the requirements of Section 7.09; 

 54 

        (e) to
      establish the form or forms or terms of Securities of any series or of
      the coupons appertaining to such Securities as permitted by Section 2.03; 

        (f) to
      provide for uncertificated or Unregistered Securities and to make all appropriate
      changes for such purpose; and 

        (g) to
      make any change that does not materially and adversely affect the rights
      of any Holder. 

      Section
      9.02. With Consent of Holders. Subject
      to Sections 6.04 and 6.07, without prior notice to any Holders, the Company
      and the Trustee may amend this Indenture and the Securities of any series
      with the written consent of the Holders of a majority in principal amount
      of the outstanding Securities of all series affected by such amendment
      (all such series voting as a separate class), and the Holders of a majority
      in principal amount of the outstanding Securities of all series affected
      thereby (all such series voting as a separate class) by written notice
      to the Trustee may waive future compliance by the Company with any provision
      of this Indenture or the Securities of such series. 

      Notwithstanding
    the provisions of this Section 9.02, without the consent of each Holder affected
    thereby, an amendment or waiver, including a waiver pursuant to Section 6.04,
    may not: 

      (a) change
    the stated maturity of the Principal of, or any sinking fund obligation or
    any installment of interest on, such Holder’s Security,

      (b) reduce
    the Principal amount thereof or the rate of interest thereon (including any
    amount in respect of original issue discount); 

      (c) reduce
    the above stated percentage of outstanding Securities the consent of whose
    holders is necessary to modify or amend the Indenture with respect to the
    Securities of the relevant series; and 

      (d) reduce
    the percentage in principal amount of outstanding Securities of the relevant
    series the consent of whose Holders is required for any supplemental indenture
    or for any waiver of compliance with certain provisions of this Indenture
    or certain Defaults and their consequences provided for in this Indenture. 

      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 Holders of Securities of such series with respect to such covenant or
    provision, 

 55 

 shall be deemed not to affect the
    rights under this Indenture of the Holders of Securities of any other series
    or of the coupons appertaining to such Securities. 

      It shall
    not be necessary for the consent of any Holder under this Section 9.02 to
    approve the particular form of any proposed amendment, supplement or waiver,
    but it shall be sufficient if such consent approves the substance thereof. 

      After
    an amendment, supplement or waiver under this Section 9.02 becomes effective,
    the Company shall give to the Holders affected thereby a notice briefly describing
    the amendment, supplement or waiver. The Company will mail supplemental indentures
    to Holders upon request. Any failure of the Company to mail 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
      9.03. Revocation and Effect of
      Consent. Until an amendment or waiver
      becomes effective, a consent to it by a Holder 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 Security of the consenting
      Holder, 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 its Security
      or portion of its Security. Such revocation shall be effective only if
      the Trustee receives the notice of revocation before the date the amendment,
      supplement or waiver becomes effective. An amendment, supplement or waiver
      shall become effective with respect to any Securities affected thereby
      on receipt by the Trustee of written consents from the requisite Holders
      of outstanding Securities affected thereby. 

      The
    Company may, but shall not be obligated to, fix a record date (which may
    be not less than five nor more than 60 days prior to the solicitation of
    consents) for the purpose of determining the Holders of the Securities of
    any series affected entitled to consent to any amendment, supplement or waiver.
    If a record date is fixed, then, notwithstanding the immediately preceding
    paragraph, those Persons who were such Holders at such record date (or their
    duly designated proxies) and only those Persons shall be entitled to consent
    to such amendment, supplement or waiver or to revoke any consent previously
    given, whether or not such Persons continue to be such Holders after such
    record date. No such consent shall be valid or effective for more than 90
    days after such record date. 

      After
    an amendment, supplement or waiver becomes effective with respect to the
    Securities of any series affected thereby, it shall bind every Holder of
    such Securities unless it is of the type described in any of clauses (a)
    through (d) of Section 9.02. In case of an amendment or waiver of the type
    described in clauses (a) through (d) of Section 9.02, the amendment or waiver
    shall bind each such Holder who has consented to it and every subsequent
    Holder of a Security that evidences the same indebtedness as the Security
    of the consenting Holder. 

 56 

      Section
      9.04. Notation on or Exchange of
      Securities. If an amendment, supplement
      or waiver changes the terms of any Security, the Trustee may require the
      Holder thereof to deliver it to the Trustee. The Trustee may place an appropriate
      notation on the Security about the changed terms and return it to the Holder
      and the Trustee may place an appropriate notation on any Security of such
      series thereafter authenticated. Alternatively, if the Company or the Trustee
      so determines, the Company in exchange for the Security shall issue and
      the Trustee shall authenticate a new Security of the same series and tenor
      that reflects the changed terms. 

      Section
      9.05. Trustee to Sign Amendments,
      Etc. The Trustee shall be entitled
      to receive, and shall be fully protected in relying upon, an Opinion of
      Counsel stating that the execution of any amendment, supplement or waiver
      authorized pursuant to this Article 9 is authorized or permitted by this
      Indenture, stating that all requisite consents have been obtained or that
      no consents are required and stating that such supplemental indenture constitutes
      the legal, valid and binding obligation of the Company, enforceable against
      the Company in accordance with its terms, subject to customary exceptions.
      The Trustee may, but shall not be obligated to, execute any such amendment,
      supplement or waiver that affects the Trustee’s own rights, duties
      or immunities under this Indenture or otherwise. 

      Section
      9.06. Conformity with Trust Indenture
      Act. Every supplemental indenture
      executed pursuant to this Article 9 shall conform to the requirements of
      the Trust Indenture Act as then in effect.

      The
    Company or the Trustee by written notice to the other may designate additional
    or different addresses for subsequent notices or communications. 

      Any
    notice or communication shall be sufficiently given to Holders of any Unregistered
    Securities, by publication at least once in an Authorized Newspaper in The
    City of New York, or with respect to any Security the interest on which is
    based on the offered quotations in the interbank Eurodollar market for dollar
    deposits at least once in an Authorized Newspaper in London, and by mailing
    to the Holders thereof who have filed their names and addresses with the
    Trustee pursuant to Section 313(c)(2) of the Trust Indenture Act at such
    addresses as were so furnished to the Trustee and to Holders of Registered
    Securities by mailing to such Holders at their addresses as they shall appear
    on the Security Register. Notice mailed shall be sufficiently given if so
    mailed within the time prescribed. Copies of any such communication or notice
    to a Holder shall also be mailed to the Trustee and each Agent at the same
    time. 

      Failure
    to mail a notice or communication to a Holder or any defect in it shall not
    affect its sufficiency with respect to other Holders. Except as otherwise
    provided in this Indenture, if a notice or communication is mailed in the
    manner provided in this Section 10.02, it is duly given, whether or not the
    addressee receives it. 

      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. 

 58 

      In case
    it shall be impracticable to give notice as herein contemplated, then such
    notification as shall be made with the approval of the Trustee shall constitute
    a sufficient notification for every purpose hereunder. 

      Section
      10.03. Certificate and Opinion
      as to Conditions Precedent. Upon any
      request or application by the Company to the Trustee to take any action
      under this Indenture, the Company shall furnish to the Trustee: 

        (a) an
      Officers’ Certificate stating that, in the opinion of the signers,
      all conditions precedent, if any, provided for in this Indenture relating
      to the proposed action have been complied with; and 

        (b) an
      Opinion of Counsel stating that, in the opinion of such counsel, all such
      conditions precedent have been complied with. 

      Section
      10.04. Statements Required in Certificate
      or Opinion. Each certificate or opinion
      with respect to compliance with a condition or covenant provided for in
      this Indenture (other than the certificate required by Section 4.04) shall
      include: 

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

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

        (c) a
      statement that, in the opinion of each such person, 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 

        (d) a
      statement as to whether or not, in the opinion of each such person, such
      condition or covenant has been complied with; provided,
      however, that, with respect to matters
      of fact, an Opinion of Counsel may rely on an Officers’ Certificate
      or certificates of public officials. 

      Section
      10.05. Evidence of Ownership. The
      Company, the Trustee and any agent of the Company or the Trustee may deem
      and treat the Holder of any Unregistered Security and the Holder of any
      coupon as the absolute owner of such Unregistered Security or coupon (whether
      or not such Unregistered Security or coupon shall be overdue) for the purpose
      of receiving payment thereof or on account thereof and for all other purposes,
      and neither the Company, the Trustee, nor any agent of the Company or the
      Trustee shall be affected by any notice to the 

 59 

 contrary. The fact of the holding
    by any Holder of an Unregistered Security, and the identifying number of
    such Security and the date of his holding the same, may be proved by the
    production of such Security or by a certificate executed by any trust company,
    bank, banker or recognized securities dealer wherever situated satisfactory
    to the Trustee, if such certificate shall be deemed by the Trustee to be
    satisfactory. Each such certificate shall be dated and shall state that on
    the date thereof a Security bearing a specified identifying number was deposited
    with or exhibited to such trust company, bank, banker or recognized securities
    dealer by the person named in such certificate. Any such certificate may
    be issued in respect of one or more Unregistered Securities specified therein.
    The holding by the person named in any such certificate of any Unregistered
    Securities specified therein shall be presumed to continue for a period of
    one year from the date of such certificate unless at the time of any determination
    of such holding (1) another certificate bearing a later date issued in respect
    of the same Securities shall be produced or (2) the Security specified in
    such certificate shall be produced by some other Person, or (3) the Security
    specified in such certificate shall have ceased to be outstanding. Subject
    to Article 7, the fact and date of the execution of any such instrument and
    the amount and numbers of Securities held by the Person so executing such
    instrument may also be proven in accordance with such reasonable rules and
    regulations as may be prescribed by the Trustee or in any other manner which
    the Trustee may deem sufficient. 

      The
    Company, the Trustee and any agent of the Company or the Trustee may deem
    and treat the person in whose name any Registered Security shall be registered
    upon the Security Register for such series as the absolute owner of such
    Registered Security (whether or not such Registered Security shall be overdue
    and notwithstanding any notation of ownership or other writing thereon) for
    the purpose of receiving payment of or on account of the Principal of and,
    subject to the provisions of this Indenture, interest on such Registered
    Security and for all other purposes; and neither the Company nor the Trustee
    nor any agent of the Company or the Trustee shall be affected by any notice
    to the contrary. 

      Section
      10.06. Rules by Trustee, Paying
      Agent or Registrar. The Trustee may
      make reasonable rules for action by or at a meeting of Holders. The Paying
      Agent or Registrar may make reasonable rules for its functions. 

      Section
      10.07. Payment Date Other Than
      a Business Day. Except as otherwise
      provided with respect to a series of Securities, if any date for payment
      of Principal or interest on any Security shall not be a Business Day at
      any place of payment, then payment of Principal of or interest on such
      Security, as the case may be, need not be made on such date, but may be
      made on the next succeeding Business Day at any place of payment with the
      same force and effect as if made on such date and no interest shall accrue
      in respect of such payment for the period from and after such date. 

 60 

      Section
      10.08. Governing Law. The
      laws of the State of New York shall govern this Indenture and the Securities. 

      Section
      10.09. No Adverse Interpretation
      of Other Agreements. This Indenture
      may not be used to interpret another indenture or loan or debt agreement
      of the Company or any Subsidiary of the Company. Any such indenture or
      agreement may not be used to interpret this Indenture. 

      Section
      10.10. Successors. All
      agreements of the Company in this Indenture and the Securities shall bind
      its successors. All agreements of the Trustee in this Indenture shall bind
      its successors. 

      Section
      10.11. Duplicate Originals. The
      parties may sign any number of copies of this Indenture. Each signed copy
      shall be an original, but all of them together represent the same agreement. 

      Section
      10.12. Separability. 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
      10.13. Table of Contents, Headings,
      Etc. The Table of Contents and headings
      of the Articles and Sections of this Indenture have been inserted for convenience

      Section
      10.14. Incorporators, Stockholders,
      Officers and Directors of Company Exempt from Individual Liability. No
      recourse under or upon any obligation, covenant or agreement contained
      in this Indenture or any indenture supplemental hereto, or in any Security
      or any coupons appertaining thereto, or because of any indebtedness evidenced
      thereby, shall be had against any incorporator, as such or against any
      past, present or future stockholder, officer, director or employee, as
      such, of the Company or of any successor, either directly or through the
      Company or any successor, under any rule of law, statute or constitutional
      provision or by the enforcement of any assessment or by any legal or equitable
      proceeding or otherwise, all such liability being expressly waived and
      released by the acceptance of the Securities and the coupons appertaining
      thereto by the holders thereof and as part of the consideration for the
      issue of the Securities and the coupons appertaining thereto. 

      Section
      10.15. 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 on the Securities of any series (the “Required
      Currency”) into a currency in
      which a judgment will be rendered (the 

 61 

 “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 Business Day, then, to the extent
      permitted by applicable law, 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 Business 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, or any recovery pursuant to any judgment (whether or not
      entered in accordance with subsection (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. 

 ARTICLE 11 

  SUBORDINATION OF SECURITIES 

      Section
      11.01. Agreement to Subordinate. The
      Company covenants and agrees, and each Holder of Securities issued hereunder
      by his acceptance thereof likewise covenants and agrees, that all Securities
      shall be issued subject to the provisions of this Article; and each person
      holding any Security, whether upon original issue or upon transfer, assignment
      or exchange thereof accepts and agrees that the Principal of and interest
      on all Securities issued hereunder shall, to the extent and in the manner
      herein set forth, be subordinated and subject in right of payment to the
      prior payment in full of all Senior Indebtedness. 

      Section
      11.02. Payments to Securityholders. No
      payments on account of Principal of or interest on the Securities shall
      be made if at the time of such payment or immediately after giving effect
      thereto there shall exist a default in any payment with respect to any
      Senior Indebtedness, and such default shall not have been cured or waived
      or shall not have ceased to exist. In addition, during the continuance
      of any default (other than a payment default) with respect to Designated
      Senior Indebtedness pursuant to which the maturity thereof may be accelerated,
      from and after the date of receipt by the Trustee of written notice from
      the holders of such Designated Senior Indebtedness or from an agent of
      such holders, stating that such default has occurred and is continuing,
      no payments on 

 62 

 account of Principal or interest in
    respect of the Securities may be made by the Company for a period (“Payment
    Blockage Period”) commencing on the date of delivery of such notice
    and ending 179 days thereafter (unless such Payment Blockage Period shall
    be terminated by written notice to the Trustee from the holders of such Designated
    Senior Indebtedness or from an agent of such holders, or such default has
    been cured or waived or has ceased to exist). Only one Payment Blockage Period
    may be commenced with respect to the Securities during any period of 360
    consecutive days. No Event of Default which existed or was continuing on
    the date of the commencement of any Payment Blockage Period with respect
    to the Designated Senior Indebtedness initiating such Payment Blockage Period
    shall be or be made the basis for the commencement of any subsequent Payment
    Blockage Period by the holders of such Designated Senior Indebtedness, unless
    such Event of Default shall have been cured or waived for a period of not
    less than 90 consecutive days. 

      Upon
    any payment or distribution of assets of the Company of any kind or character,
    whether in cash, property or securities, to creditors upon any liquidation,
    dissolution, winding up, receivership, reorganization, assignment for the
    benefit of creditors, marshalling of assets and liabilities or any bankruptcy,
    insolvency or similar proceedings of the Company, all amounts due or to become
    due upon all Senior Indebtedness shall first be paid in full, in cash or
    cash equivalents, or payment thereof provided for in accordance with its
    terms, before any payment is made on account of the Principal of, or interest
    on the indebtedness evidenced by the Securities, and upon any such liquidation,
    dissolution, winding up, receivership, reorganization, assignment, marshalling
    or proceeding, any payment or distribution of assets of the Company of any
    kind or character, whether in cash, property or securities, to which the
    Holders of the Securities or the Trustee under this Indenture would be entitled,
    except for the provisions hereof, shall be paid by the Company or by any
    receiver, trustee in bankruptcy, liquidating trustee, agent or other Person
    making such payment or distribution, directly to the holders of Senior Indebtedness
    (pro rata to such holders on the basis of the respective amounts of Senior
    Indebtedness held by such holders) or their respective representatives, or
    to the trustee or trustees under any indenture pursuant to which any instruments
    evidencing any of such Senior Indebtedness may have been issued, as their
    respective interests may appear, to the extent necessary to pay all Senior
    Indebtedness in full (including, without limitation, except to the extent,
    if any, prohibited by mandatory provisions of law, post-petition interest,
    in any such proceedings), after giving effect to any concurrent payment or
    distribution to or for the holders of Senior Indebtedness, before any payment
    or distribution is made to the holders of the indebtedness evidenced by the
    Securities or to the Trustee under this Indenture. 

      In the
    event that, notwithstanding the foregoing, any payment or distribution of
    assets of the Company of any kind or character, whether in cash, 

 63 

 property or securities, prohibited
    by the foregoing, shall be received by the Trustee under this Indenture or
    the Holders of the Securities before all Senior Indebtedness is paid in full
    or provision is made for such payment in accordance with its terms, such
    payment or distribution shall be held in trust for the benefit of and shall
    be paid over or delivered to the holders of such Senior Indebtedness or their
    respective representatives, or to the trustee or trustees under any indenture
    pursuant to which any instruments evidencing any of such Senior Indebtedness
    may have been issued, as their respective interests may appear, for application
    to the payment of all Senior Indebtedness remaining unpaid until all such
    Senior Indebtedness shall have been paid in full in accordance with its terms,
    after giving effect to any concurrent payment or distribution to or for the
    holders of such Senior Indebtedness. 

      For
    purposes of this Article, the words, “cash, property or securities” shall
    not be deemed to include shares of stock of the Company as reorganized or
    readjusted, or securities of the Company or any other corporation provided
    for by a plan of arrangement, reorganization or readjustment, the payment
    of which is subordinated (at least to the extent provided in this Article
    with respect to the Securities) to the payment of all Senior Indebtedness
    which may at the time be outstanding; provided,
    that (i) the Senior Indebtedness is assumed by the new corporation, if any,
    resulting from any such arrangement, reorganization or readjustment, and
    (ii) the rights of the holders of the Senior Indebtedness are not, without
    the consent of such holders, altered by such arrangement, reorganization
    or readjustment. The consolidation of the Company with, or the merger of
    the Company into, another corporation or the liquidation or dissolution of
    the Company following the sale, conveyance or transfer of all or substantially
    all of its property and assets to another corporation upon the terms and
    conditions provided in Article 5 shall not be deemed
    a dissolution, winding-up, liquidation or reorganization for the purposes
    of this Section if such other corporation shall, as a part of such consolidation,
    merger, sale, conveyance or transfer, comply with the conditions stated in Article
    5.
    Nothing in this Section shall apply to claims of, or payments to, the Trustee
    under or pursuant to Article 7. This Section shall be subject
    to the further provisions of Section 11.05. 

      Section
      11.03. Subrogation of Securities. Subject
      to the payment in full of all Senior Indebtedness, the Holders of the Securities
      shall be subrogated to the rights of the holders of Senior Indebtedness
      to receive payments or distributions of cash, property or securities of
      the Company applicable to the Senior Indebtedness until the principal of
      and interest on the Securities shall be paid in full; and, for the purposes
      of such subrogation, no payments or distributions to the holders of the
      Senior Indebtedness of any cash, property or securities to which the Holders
      of the Securities or the Trustee on their behalf would be entitled except
      for the provisions of this Article, and no payment over pursuant to the
      provisions 

 64 

 of this Article to the holders of
    Senior Indebtedness by Holders of the Securities or the Trustee on their
    behalf shall, as between the Company, its creditors other than holders of
    Senior Indebtedness and the Holders of the Securities, be deemed to be a
    payment by the Company to or on account of the Senior Indebtedness; and no
    payments or distributions of cash, property or securities to or for the benefit
    of the Securityholders pursuant to the subrogation provision of this Article,
    which would otherwise have been paid to the holders of Senior Indebtedness
    shall be deemed to be a payment by the Company to or for the account of the
    Securities. It is understood that the provisions of this Article are and
    are intended solely for the purpose of defining the relative rights of the
    holders of the Securities, on the one hand, and the Holders of the Senior
    Indebtedness, on the other hand. 

      Nothing
    contained in this Article or elsewhere in this Indenture or in the Securities
    is intended to or shall impair, as between the Company, its creditors other
    than the holders of Senior Indebtedness, and the Holders of the Securities,
    the obligation of the Company, which is absolute and unconditional, to pay
    to the Holders of the Securities the Principal of and interest on the Securities
    as and when the same shall become due and payable in accordance with their
    terms, or is intended to or shall affect the relative rights of the Holders
    of the Securities and creditors of the Company other than the holders of
    the Senior Indebtedness, nor shall anything herein or therein prevent the
    Holder of any Security or the Trustee on his behalf from exercising all remedies
    otherwise permitted by applicable law upon default under this Indenture,
    subject to the rights, if any, under this Article of the holders of Senior
    Indebtedness in respect of cash, property or securities of the Company received
    upon the exercise of any such remedy. 

      Upon
    any payment or distribution of assets of the Company referred to in this
    Article, the Trustee, subject to the provisions of Sections 7.01 and
    7.02, and the
    holders of the Securities shall be entitled to rely upon any order or decree
    made by any court of competent jurisdiction in which such liquidation, dissolution,
    winding up, receivership, reorganization, assignment or marshalling proceedings
    are pending, or a certificate of the receiver, trustee in bankruptcy, liquidating
    trustee, agent or other person making such payment or distribution, delivered
    to the Trustee or to the Holders of the Securities, for the purpose of ascertaining
    the Persons entitled to participate in such distribution, the holders of
    the Senior Indebtedness and other indebtedness of the Company, the amount
    thereof or payable thereon, the amount or amounts paid or distributed thereon
    and all other facts pertinent thereto or to this Article. 

      Section
      11.04. Authorization by Securityholders. Each
      Holder of a Security by his acceptance thereof authorizes the Trustee in
      his behalf to take such action as may be necessary or appropriate to effectuate
      the subordination 

 65 

 provided in this Article and appoints
    the Trustee his attorney-in-fact for any and all such purposes. 

      Section
      11.05. Notice to Trustee. The
      Company shall give prompt written notice to the Trustee and to any paying
      agent of any fact known to the Company which would prohibit the making
      of any payment of moneys to or by the Trustee or any paying agent in respect
      of the Securities pursuant to the provisions of this Article or would end
      such prohibition. Regardless of anything to the contrary contained in this
      Article or elsewhere in this Indenture, the Trustee shall not be charged
      with knowledge of the existence of any Senior Indebtedness or of any default
      or event of default with respect to any Senior Indebtedness or of any other
      facts which would prohibit the making of any payment of moneys to or by
      the Trustee or which would end such prohibition, unless and until the Trustee
      shall have received notice in writing at its principal Corporate Trust
      Office to that effect signed by an officer of the Company, or by a holder
      or agent of a holder of Senior Indebtedness or by the trustee under any
      indenture pursuant to which Senior Indebtedness shall be outstanding, who
      shall have been certified by the Company or otherwise established to the
      reasonable satisfaction of the Trustee to be such holder or agent or trustee,
      and, prior to the receipt of any such written notice, the Trustee shall,
      subject to Sections 7.01 and 7.02, be entitled
      to assume that no such facts exist; provided that if on a date at least
      three Business Days prior to the date upon which by the terms hereof any
      such moneys shall become payable for any purpose (including, without limitation,
      the payment of the Principal of, or interest on any Security) the Trustee
      shall not have received with respect to such moneys the notice of prohibition
      provided for in this Section, then, regardless of anything herein to the
      contrary, the Trustee shall have full power and authority to receive such
      moneys and to apply the same to the purpose for which they were received,
      and shall not be affected by any notice to the contrary which may be received
      by it on or after such prior date. 

      Regardless
    of anything to the contrary herein, nothing shall prevent (a) any payment
    by the Company or the Trustee to the Securityholders of amounts in connection
    with a redemption of Securities if (i) notice of such redemption has been
    given pursuant to Article 3 prior to the receipt by the
    Trustee of written notice of prohibition as aforesaid, and (ii) such notice
    of redemption is given not earlier than 60 days before the redemption date,
    or (b) any payment by the Trustee to the Securityholders of amounts deposited
    with it pursuant to Sections 8.01, 8.05 or 8.06.

      The
    Trustee shall be entitled to rely on the delivery to it of a written notice
    by a Person representing himself to be a holder of Senior Indebtedness (or
    a trustee or agent on behalf of such holder) to establish that such notice
    has been 

 66 

 given by a holder of Senior Indebtedness
    or a trustee or agent on behalf of any such holder. In the event that the
    Trustee determines in good faith that further evidence is required with respect
    to the right of any Person as a holder of Senior Indebtedness to participate
    in any payment or distribution pursuant to this Article, the Trustee may
    request such Person to furnish evidence to the reasonable satisfaction of
    the Trustee as to the amount of Senior Indebtedness held by such Person,
    the extent to which such Person is entitled to participate in such payment
    or distribution and any other facts pertinent to the rights of such Person
    under this Article, and if such evidence is not furnished the Trustee may
    defer any payment to such Person pending judicial determination as to the
    right of such Person to receive such payment. 

      Section
      11.06. Trustee’s Relation
      to Senior Indebtedness. The Trustee
      and any agent of the Company or the Trustee shall be entitled to all the
      rights set forth in this Article with respect to any Senior Indebtedness
      which may at any time be held by it in its individual or any other capacity
      to the same extent as any other holder of Senior Indebtedness and nothing
      in this Indenture shall deprive the Trustee or any such agent, of any of
      its rights as such holder. Nothing in this Article shall apply to claims
      of, or payments to, the Trustee under or pursuant to 7.07.

      With
    respect to the holders of Senior Indebtedness, the Trustee undertakes to
    perform or to observe only such of its covenants and obligations as are specifically
    set forth in this Article, and no implied covenants or obligations with respect
    to the holders of Senior Indebtedness shall be read into this Indenture against
    the Trustee. The Trustee shall not be deemed to owe any fiduciary duty to
    the holders of Senior Indebtedness and, subject to the provisions of Sections 7.01
    and 7.02, the Trustee
    shall not be liable to any holder of Senior Indebtedness if it shall pay
    over or deliver to Holders of Securities, the Company or any other Person
    moneys or assets to which any holder of Senior Indebtedness shall be entitled
    by virtue of this Article or otherwise. 

      Section
      11.07. No Impairment of Subordination. No
      right of any present or future holder of any Senior Indebtedness to enforce
      subordination as herein provided shall at any time in any way be prejudiced
      or impaired by any act or failure to act on the part of the Company or
      by any act or failure to act, in good faith, by any such holder, or by
      any noncompliance by the Company with the terms, provisions and covenants
      of this Indenture, regardless of any knowledge thereof which any such holder
      may have or otherwise be charged with.
