    The
      terms
      and provisions contained in the Securities shall constitute, and are hereby
      expressly made, a part of this Indenture and the Company and the Trustee, by
      their execution and delivery of this Indenture, expressly agree to such terms

      however,
      to the
      extent permitted by applicable law, if any provision of any Security conflicts
      with the express provisions of this Indenture, the provisions of this Indenture
      shall govern and be controlling.

     

    (b)  Restricted
      Global Securities.
      All of
      the Securities shall be issued initially in the form of one or more Restricted

      Securities represented thereby with the Securities Custodian, as custodian
      for
      the depositary, The Depository Trust Company (such depositary, or any successor
      thereto, being hereinafter referred to as the “Depositary”),

      registered in the name of its nominee, Cede & Co., or as otherwise
      instructed by the Depositary, duly executed by the Company and authenticated

      adjustments made on the records of the Securities Custodian and the Depositary
      as hereinafter provided, subject in each case to compliance with the Applicable
      Procedures and the provisions of this Indenture.

      amount of outstanding Securities from time to time endorsed thereon and that
      the
      aggregate amount of outstanding Securities represented thereby may from time
      to
      time be reduced or increased, as appropriate, to reflect exchanges, purchases,
      redemptions or conversions of such Securities, in each case in accordance with
      this Indenture. Any adjustment of the aggregate principal amount of a Global
      Security to reflect the amount of any increase or decrease in the amount of

      2.12 hereof, or otherwise in accordance with this Indenture, and shall be made
      on the records of the Trustee and the Depositary.

      shall
      have no rights under this Indenture with respect to any Global Security held
      on
      their behalf by the Depositary or under the Global Security, and the Depositary
      (including, for this purpose, its nominee) may be treated by the Company, the
      Trustee and any agent of the Company or the Trustee as the absolute owner and
      Holder of such Global Security for all purposes whatsoever.

     

    None
      of
      the Company, the Trustee, the Registrar, any Paying Agent or any agent of any
      of
      them shall have any responsibility or liability for any aspect of the records
      relating to or payments made on account of beneficial ownership interests in
      the
      Securities, for maintaining, supervising or reviewing any records relating
      to
      such beneficial owner interests, or for any acts or omissions of a Depositary
      or
      for any transactions between a Depositary and any beneficial owner or between
      or
      among beneficial owners. No owner of a beneficial interest in the Securities
      shall have any rights under this Indenture, and the Depositary or its nominee,

    Notwithstanding
      the foregoing, nothing herein shall (A) prevent the Company, the Trustee or
      any
      agent of the Company or the Trustee from giving effect to any written
      certification, proxy or other authorization furnished by the Depositary, or
      its
      nominee, as the case may be, or (B) impair, as between the Depositary and its
      Agent Members, the Applicable Procedures or the operation of customary practices
      governing the exercise of the rights of a Holder of any Security.

     

    (e)  Certificated
      Securities.
      Certificated Securities shall be issued only under the circumstances provided
      in
      Section 2.12(a)(i).

     

    Section
      2.02   Execution
      and Authentication.

     

     (a)
      A duly
      authorized Officer of the Company shall sign the Securities for the Company
      by
      manual or facsimile signature.

     

    (b)  If
      an
      Officer of the Company whose signature is on a Security no longer holds that
      office at the time the Trustee authenticates the Security, the Security shall
      be
      valid nevertheless.

     

    (c)  A
      Security shall not be valid until an authorized signatory of the Trustee
      manually signs the certificate of authentication on the Security. The signature
      shall be conclusive evidence that the Security has been authenticated under
      this
      Indenture.

     

    (d)  The
      Trustee shall initially authenticate and make available for delivery Securities
      for original issue in the
      aggregate principal amount of up to $700,000,000 upon receipt of a written
      order
      or orders of the Company signed by an Officer of the Company (a “Company
      Order”).
      The
      Company may, without the consent of the Holders, issue additional Securities
      (the “Additional
      Securities”)
      with
      the same terms and with the same CUSIP number as the Securities in an unlimited
      aggregate principal amount; provided,
      however
      that no
      such Additional Securities may be issued unless fungible with the Securities
      for
      U.S. federal income tax purposes. The Trustee shall authenticate Additional
      Securities thereafter in unlimited aggregate principal amount (so long as
      permitted by the terms of this Indenture) for original issue upon a Company
      Order of the Company in aggregate principal amount as specified in such order
      (except as provided in Section 2.07). Each such Company Order shall specify
      the
      amount of Securities to be authenticated and the date on which the Securities
      are to be authenticated. Such Additional Securities shall have identical terms
      to the Initial Securities except for issuance dates and prices and with respect
      to interest accruing prior to their date of issuance, and will constitute the
      same series as the Initial Securities for all purposes hereunder, including,
      without limitation, waivers, amendments and offers to purchase.

     

    (e)  The
      Trustee shall act as the initial authenticating agent. Thereafter, the Trustee
      may appoint an authenticating agent acceptable to the Company to authenticate
      Securities. An authenticating agent may authenticate Securities whenever the
      Trustee may do so. Each reference in this Indenture to authentication by the
      Trustee includes authentication by such Agent. An authenticating agent shall
      have the same rights as an Agent to deal with the Company or an Affiliate of
      the
      Company.

     

    The
      Securities shall be issuable only in registered form without coupons and only
      in
      denominations of $1,000 principal amount and any integral multiple
      thereof.

     

    Section

      Paying Agent and Conversion Agent.

     

    The
      Company shall maintain an office or agency where Securities may be presented
      for
      registration of transfer or for exchange (“Registrar”),
      an
      office or agency in the United States where Securities may be presented for
      purchase or payment (“Paying
      Agent”),
      an
      office or agency where Securities may be presented for conversion (“Conversion
      Agent”)
      and an
      office or agency where notices and demands to or upon the Company in respect
      of
      the Securities and this Indenture may be served. The Registrar shall keep a
      register of the Securities (“Register”)
      and of
      their transfer and exchange.

    The
      Company may have one or more co-registrars, one or more additional paying
      agents, and one or more additional conversion agents. The term “Registrar”
includes any co-registrar, including any named pursuant to Section 9.06. The
      term “Paying Agent” includes any additional paying agent, including any named
      pursuant to Section 9.06. The term “Conversion Agent” includes any additional
      conversion agent, including any named pursuant to Section 9.06.

     

    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 that relate to such Agent. The Company shall notify the Trustee of
      the
      name and address of any Agent not a party to this Indenture. If the Company
      fails to maintain a Registrar, Paying Agent or Conversion Agent or agent for
      service of notices and demands in any place required by this Indenture, or
      fails
      to give the foregoing notice, the Trustee shall act as such. The Company or
      any
      Affiliate of the Company may act as Paying Agent.

     

    The
      Company hereby initially appoints the Trustee as Registrar, Paying Agent and
      Conversion Agent in connection with the Securities.

     

    Section

      or
      delivery of Cash or shares of Common Stock, as applicable and as provided
      herein, the Company shall deposit with the Paying Agent Cash (in immediately
      available funds if deposited on the due date) or with the Conversion Agent
      such
      number of shares of Common Stock or other consideration sufficient to make
      such
      payments or deliveries when so becoming due. The Company shall require each
      Paying Agent or Conversion Agent, as applicable (other than the Trustee), to
      agree in writing that such Agent shall hold in trust for the benefit of
      Securityholders or the Trustee all Cash, Common Stock or other consideration,
      as
      applicable, held by such Agent for the making of payments or deliveries in
      respect of the Securities and shall notify the Trustee in writing of any default
      by the Company in making any such payment or delivery. If the Company or an
      Affiliate of the Company acts as Paying Agent or Conversion Agent, as
      applicable, it shall segregate the Cash, Common Stock and other consideration,
      as applicable, held by it as Paying Agent or Conversion Agent, as applicable,
      and hold it as a separate trust fund.

     

    The
      Company at any time may require a Paying Agent or Conversion Agent, as
      applicable, to pay all Cash, Common Stock or other consideration, as applicable,
      held by it to the Trustee, and the Trustee may at any time during the
      continuance of any Default, upon written request to the Paying Agent or the
      Conversion Agent, as applicable, require such Paying Agent or Conversion Agent,
      as applicable, to pay forthwith to the Trustee all Cash, Common Stock or other
      consideration, as applicable, so held in trust by such Paying Agent or
      Conversion Agent. Upon doing so, the Paying Agent or the Conversion Agent,
      as
      applicable, shall have no further liability for such Cash, Common Stock or
      other
      consideration, as applicable.

    The
      Trustee shall preserve in as current a form as is reasonably practicable the
      most recent list available to it of the names and addresses of the
      Securityholders. If the Trustee is not the Registrar, the Company shall furnish
      to the Trustee on or before each Interest Payment Date, and at such other times
      as the Trustee may request in writing, a list of the names and addresses of
      the
      Securityholders in such form and as of such date as the Trustee may reasonably
      request.

    Section
      2.06   Transfer
      and Exchange.

     

     (a)
      Subject
      to compliance with any applicable additional requirements contained in Section
      2.12, when a Security is presented to a Registrar with a request to register
      a
      transfer thereof or to exchange such Security for an equal principal amount
      of
      Securities of other authorized denominations, the Registrar shall register
      the
      transfer or make the exchange as requested; provided,
      however,
      that
      every Security presented or surrendered for registration of transfer or exchange
      shall, if such Security is a Certificated Security, be duly endorsed or
      accompanied by an assignment form, in the form included in Exhibit A attached
      hereto and, if applicable, a transfer certificate, in the form included in
      Exhibit A attached hereto, and in form reasonably satisfactory to the Registrar
      duly executed by the Holder thereof or its attorney duly authorized in writing.
      To permit registration of transfers and exchanges, upon surrender of any
      Security for registration of transfer or exchange at an office or agency
      maintained pursuant to Section 2.03, the Company shall execute and the Trustee
      shall, upon receipt of a Company Order, authenticate Securities of a like
      aggregate principal amount at the Registrar’s request. Any exchange or transfer
      shall be without charge, except that the Company or the Registrar may require
      payment of a sum sufficient to cover any tax, assessment or other governmental
      charge that may be imposed in relation thereto, other than exchanges pursuant
      to
      Section 2.10, Section 13.05, Article 5 or Article 7, in each case, not involving
      any transfer.

     

    Neither
      the Company, any Registrar nor the Trustee shall be required to exchange or
      register a transfer of any Securities or portions thereof selected for
      redemption (except, in the case of Securities to be redeemed in part, the
      portion thereof not to be redeemed) or any Securities in respect of which a
      Repurchase Notice or Fundamental Change Purchase Notice has been delivered
      and
      not validly withdrawn by the Holder thereof (except, in the case of the purchase
      of a Security in part, the portion thereof not to be purchased).

     

    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.

     

    (b)  Any
      Registrar appointed pursuant to Section 2.03 or Section 9.06 hereof shall
      provide to the Trustee such information as the Trustee may reasonably request
      in
      connection with the delivery by such Registrar of Securities upon transfer
      or
      exchange of Securities.

     

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

     

    Any
      Holder of a Global Security shall, by acceptance of such Global Security, agree
      that transfers of beneficial interests in such Global Security may be effected
      only through a book-entry system maintained by the Depositary (or its agent),
      and that ownership of a beneficial interest in a Global Security shall be
      required to be reflected in a book-entry system.

     

    Section
      2.07   Replacement
      Securities.

     

    If
      (a)
      any mutilated Security is surrendered to the Company, a Registrar or the
      Trustee, or (b) the Company, the Registrar and the Trustee receive evidence
      to
      their satisfaction of the destruction, loss or theft of any Security, and,
      in
      either case, there is delivered to the Company, the Registrar and the Trustee
      such security or indemnity as shall be reasonably required by them to save
      each
      of them harmless, then, in the absence of notice to the Company, such Registrar
      or the Trustee that such Security has been acquired by a bona fide or protected
      purchaser, the Company shall issue, and the Trustee shall, upon receipt of
      a
      Company Order (which the Company agrees to deliver promptly), authenticate
      and
      deliver, in exchange for any such mutilated Security or in lieu of any such
      destroyed, lost or stolen Security, a new Security of like tenor and principal
      amount, bearing a number not contemporaneously outstanding.

     

    
      
        
        

      

      
        13

        
          

        

      

      
        
        

      

    

    In
      case
      any such mutilated, destroyed, lost or stolen Security has become or is about
      to
      become due and payable, or is about to be redeemed or purchased by the Company
      pursuant to Article 5, the Company in its discretion may, instead of issuing
      a
      new Security, pay, redeem or purchase such Security, as the case may be, in
      accordance herewith.

     

    Upon
      the
      issuance of any new Securities under this Section 2.07, the Company may require
      the payment of a sum sufficient to cover any tax, assessment or other
      governmental charge that may be imposed in relation thereto as the result of
      any
      Securities, at the request of any Holder, being issued to a Person other than
      such Holder and any other reasonable expenses (including the reasonable fees
      and
      expenses of the Trustee or the Registrar) in connection therewith.

     

    Every
      new
      Security issued pursuant to this Section 2.07 in lieu of any mutilated,
      destroyed, lost or stolen Security shall constitute an original additional
      contractual obligation of the Company, whether or not the mutilated, destroyed,
      lost or stolen Security shall be at any time enforceable by anyone, and shall
      be
      entitled to all benefits of this Indenture equally and proportionately with
      any
      and all other Securities duly issued and outstanding hereunder.

     

    The
      provisions of this Section 2.07 are (to the extent lawful) exclusive and shall
      preclude (to the extent lawful) all other rights and remedies with respect
      to
      the replacement or payment of mutilated, destroyed, lost or stolen
      Securities.

     

    Section
      2.08   Outstanding
      Securities.

     

    Securities
      outstanding at any time are all Securities authenticated by the Trustee, except
      for those canceled by it, those paid, redeemed or repurchased, those delivered
      to it for cancellation and those described in this Section 2.08 as not
      outstanding.

     

    If
      a
      Security is replaced pursuant to Section 2.07 (other than a mutilated Security
      surrendered for replacement), it ceases to be outstanding unless the Trustee
      receives, subsequent to the new Security’s authentication, proof satisfactory to
      the Company that the replaced Security is held by a bona fide or protected
      purchaser. A mutilated Security ceases to be outstanding upon surrender and
      replacement thereof pursuant to Section 2.07.

     

    If
      the
      Paying Agent holds, in accordance with the terms of this Indenture, prior to
      11:00 a.m., New York City time, on the Maturity Date, a Redemption Date or
      Repurchase Date, as the case may be, Cash sufficient to pay all Initial
      Securities and all Additional Securities then payable, then on and after such
      Maturity Date, Redemption Date or Repurchase Date, as the case may be, such
      Securities shall cease to be outstanding and interest (including Contingent
      Interest or Additional Interest, if any) on such Securities shall cease to
      accrue.

     

    If
      a
      Security is converted in accordance with Article 7, then on the Conversion
      Date,
      such Security shall cease to be outstanding and interest (including Contingent
      Interest or Additional Interest, if any) on such Security shall cease to accrue,
      unless there shall be a default in the delivery of the consideration payable
      hereunder upon such conversion.

     

    Subject
      to the restrictions contained in Section 2.09, a Security does not cease to
      be
      outstanding solely because the Company or an Affiliate of the Company holds
      the
      Security.

    Section
      2.09   Treasury
      Securities.

     

    In
      determining whether the Holders of the required principal amount of Securities
      have given or concurred in any notice, request, demand, authorization,
      direction, waiver or consent, Securities owned by the Company or any other
      obligor on the Securities or by any Affiliate of the Company or of such other
      obligor shall be disregarded and deemed not to be outstanding for such purposes,
      except that, for purposes of determining whether the Trustee shall be protected
      in relying on any such notice, request, demand, authorization, direction, waiver
      or consent, only Securities which a Trust Officer actually knows are so owned
      shall be so disregarded. Securities so owned which have been pledged in good
      faith shall not be disregarded if the pledgee establishes to the satisfaction
      of
      the Trustee the pledgee’s right so to act with respect to the Securities and
      that the pledgee is not, and is not acting on the behalf of, the Company or
      any
      other obligor on the Securities or any Affiliate of the Company or of such
      other
      obligor. If requested by the Trustee, the Company agrees to notify the Trustee
      in writing of the existence of any such treasury Securities or Securities owned
      by the Company, any other obligor on the Securities, or, to the knowledge of
      the
      Company, any Affiliate of the Company.

     

    Section
      2.10   Temporary
      Securities.

     

    Until
      definitive Securities are ready for delivery, the Company may prepare and
      execute, and, upon receipt of a Company Order, the Trustee shall authenticate
      and deliver, temporary Securities. Temporary Securities shall be substantially
      in the form of definitive Securities but may have variations that the Company
      reasonably considers appropriate for temporary Securities. After the preparation
      of definitive Securities, the temporary Securities shall be exchangeable for
      definitive Securities upon surrender of the temporary Securities at the office
      or agency of the Company designated for such purpose pursuant to Section 2.03,
      without charge to the Holder. Upon surrender for cancellation of any one or
      more
      temporary Securities, the Company shall execute and the Trustee shall, upon
      receipt of a Company Order (which the Company agrees to deliver promptly),
      authenticate and deliver in exchange therefor a like principal amount of
      definitive Securities of authorized denominations. Until so exchanged the
      temporary Securities shall in all respects be entitled to the same benefits
      under this Indenture as definitive Securities.

     

    Section
      2.11   Cancellation.

     

    The
      Company at any time may deliver Securities to the Trustee for cancellation.
      The
      Registrar, the Paying Agent and the Conversion Agent shall forward to the
      Trustee or its agent any Securities surrendered to them for transfer, exchange,
      purchase, payment, redemption or conversion. The Trustee and no one else shall
      cancel, in accordance with its standard procedures, all Securities surrendered
      for transfer, exchange, payment, conversion or cancellation and shall deliver
      the canceled Securities to the Company. The Company may not issue new Securities
      to replace Securities that it has paid or delivered to the Trustee for
      cancellation or that any Holder has converted pursuant to Article
      7.

     

    All
      Securities that are purchased pursuant to Article 5 or otherwise acquired by
      the
      Company shall be delivered to the Trustee for cancellation. If the Company
      shall
      acquire any of the Securities, such acquisition shall not operate as a
      repurchase or satisfaction of the indebtedness represented by such Securities
      unless and until the same are delivered to the Trustee for
      cancellation.

     

    Section
      2.12   Legend;
      Additional Transfer and Exchange Requirements.

     

     (a) Transfer
      and Exchange of Global Securities.
      (i)
      Certificated Securities (x) shall be issued in exchange for interests in the
      Global Securities only if the Depositary notifies the Company that it is
      unwilling or unable to continue as Depositary for the Global Securities or
      if it
      at any time ceases to be a “clearing agency” registered under the Exchange Act,
      if so required by applicable law or regulation, and a successor Depositary
      is
      not appointed by the Company within 90 days of such notice or (y) may be issued
      in exchange for interests in the Global Securities, at a Holder’s election, if
      an Event of Default has occurred and is continuing, each of clauses (x) and
      (y)
      in accordance with the Applicable Procedures. In any such case, the Company
      shall execute, and the Trustee shall, upon receipt of a Company Order (which
      the
      Company agrees to deliver promptly), authenticate and deliver Certificated
      Securities in an aggregate principal amount equal to the principal amount of
      such Global Securities in exchange therefor. Only Restricted Certificated
      Securities shall be issued in exchange for beneficial interests in Restricted
      Global Securities, and only Unrestricted Certificated Securities shall be issued
      in exchange for beneficial interests in Unrestricted Global Securities.
      Certificated Securities issued in exchange for beneficial interests in Global
      Securities shall be registered in such names and shall be in such authorized
      denominations as the Depositary, pursuant to instructions from its Agent Members
      or otherwise in accordance with the Applicable Procedures, shall instruct the
      Trustee. The Trustee shall deliver or cause to be delivered such Certificated
      Securities to the Persons in whose name such Securities are so registered.
      Such
      exchange shall be effected in accordance with the Applicable Procedures. In
      the
      event that the Certificated Securities are not issued to each such beneficial
      owner promptly after the Registrar has received a request from the Depositary
      to
      issue such Certificated Securities, the Company expressly acknowledges, with
      respect to the right of any Holder to pursue a remedy pursuant to Section 11.06
      or 11.07 hereof, the right of any beneficial holder of Securities to pursue
      such
      remedy with respect to the portion of the Global Security that represents such
      Beneficial Owner’s Securities as if such Certificated Securities had been
      issued.

     

    
      
        
        

      

      
        15

        
          

        

      

      
        
        

      

    

    (ii)  Notwithstanding
      any other provisions of this Indenture other than the provisions set forth
      in
      Section 2.12(a)(i), a Global Security may not be transferred except as a whole
      by the Depositary to a 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.

     

    (b)  Transfer
      and Exchange of Certificated Securities.
      In the
      event that Certificated Securities are issued in exchange for beneficial
      interests in Global Securities in accordance with Section 2.12(a)(i), and,
      on or
      after such event, Certificated Securities are presented by a Holder to the
      Registrar with a request:

     

    (x) to
      register the transfer of the Certificated Securities to a person who shall
      take
      delivery thereof in the form of Certificated Securities only; or

     

    (y) to
      exchange such Certificated Securities for an equal principal amount of
      Certificated Securities of other authorized denominations,

     

    such
      Registrar shall register the transfer or make the exchange as requested;
provided,
      however,
      that
      the Certificated Securities presented or surrendered for register of transfer
      or
      exchange:

     

    (i)  shall
      be
      duly endorsed or accompanied by a written instrument of transfer in accordance
      with the proviso to the first sentence of Section 2.06(a); and

     

    (ii)  in
      the
      case of a Restricted Certificated Security, such request shall be accompanied
      by
      the following additional information and documents, as applicable:

     

    (A)  if
      such
      Restricted Certificated Security is being delivered to the Registrar by a Holder
      for registration in the name of such Holder, without transfer, or such
      Restricted Certificated Security is being transferred to the Company or a
      Subsidiary of the Company, a certification to that effect from such Holder
      (in
      substantially the form set forth in Exhibit A);

     

    (B)  if
      such
      Restricted Certificated Security is being transferred to a person the Holder
      reasonably believes is a QIB in accordance with Rule 144A, or pursuant to an
      effective registration statement under the Securities Act or in compliance
      with
      Regulation S under the Securities Act, a certification to that effect from
      such
      Holder (in substantially the form set forth in Exhibit A);

     

    (C)  if
      such
      Restricted Certificated Security is being transferred pursuant to an exemption
      from the registration requirements of the Securities Act in accordance with
      Rule
      144 or pursuant to and in compliance with another exemption from the
      registration requirements under the Securities Act, a certification to that
      effect from the Holder (in substantially the form set forth in Exhibit A) and,
      if the Company or the Registrar so requests, an Opinion of Counsel, certificates
      and other information reasonably acceptable to the Company to the effect that
      such transfer does not require registration under the Securities
      Act.

     

    
      
        
        

      

      
        16

        
          

        

      

      
        
        

      

    

    (c)  Transfer
      of a Beneficial Interest in a Restricted Global Security for a Beneficial
      Interest in an Unrestricted Global Security.
      Any
      person having a beneficial interest in a Restricted Global Security may upon
      request, subject to the Applicable Procedures, transfer such beneficial interest
      to a Person who is required or permitted to take delivery thereof in the form
      of
      a beneficial interest in an Unrestricted Global Security. Upon receipt by the
      Trustee of written instructions, or such other form of instructions as is
      customary for the Depositary, from the Depositary or its nominee on behalf
      of
      any Person having a beneficial interest in a Restricted Global Security and
      the
      following additional information and documents in such form as is customary
      for
      the Depositary from the Depositary or its nominee on behalf of the Person having
      such beneficial interest in the Restricted Global Security (all of which may
      be
      submitted by facsimile or electronically):

     

    (i)  if
      such
      beneficial interest is being transferred pursuant to an effective registration
      statement under the Securities Act, a certification to that effect from the
      Holder (in substantially the form set forth in Exhibit A); or

     

    (ii)  if
      such
      beneficial interest is being transferred pursuant to an exemption from the
      registration requirements of the Securities Act in accordance with Rule 144,
      a
      certification to that effect from the Holder (in substantially the form set
      forth in Exhibit A) and, if the Company or the Trustee so requests, an Opinion
      of Counsel, certificates and other information reasonably acceptable to the
      Company to the effect that such transfer does not require registration under
      the
      Securities Act;

     

    the
      Registrar shall reduce or cause to be reduced the aggregate principal amount
      of
      the Restricted Global Security by the appropriate principal amount and shall
      increase or cause to be increased the aggregate principal amount of the
      Unrestricted Global Security by a like principal amount. Such transfer shall
      otherwise be effected in accordance with the Applicable Procedures. If no
      Unrestricted Global Security is then outstanding, the Company shall execute
      and
      the Trustee shall, upon receipt of a Company Order (which the Company agrees
      to
      deliver promptly), authenticate and deliver an Unrestricted Global
      Security.

     

    (d)  Transfer
      of a Beneficial Interest in an Unrestricted Global Security for a Beneficial
      Interest in a Restricted Global Security.
      Any
      person having a beneficial interest in an Unrestricted Global Security may
      upon
      request, subject to the Applicable Procedures, transfer such beneficial interest
      to a person who is required or permitted to take delivery thereof in the form
      of
      a beneficial interest in a Restricted Global Security. Upon receipt by the
      Trustee of written instructions, or such other form of instructions as is
      customary for the Depositary, from the Depositary or its nominee on behalf
      of
      any person having a beneficial interest in an Unrestricted Global Security
      and
      the following additional information and documents in such form as is customary
      for the Depositary, from the Depositary or its nominee on behalf of the person
      having such beneficial interest in the Unrestricted Global Security (all of
      which may be submitted by facsimile or electronically):

     

    
      
        
        

      

      
        17

        
          

        

      

      
        
        

      

    

    (i)  a
      certification from the Holder (in substantially the form set forth in Exhibit
      A)
      to the effect that such beneficial interest is being transferred to a person
      that the transferor reasonably believes is a QIB in accordance with Rule
      144A;

     

    (ii)  a
      certification from the Holder (in substantially the form set forth in Exhibit
      A)
      to the effect that such beneficial interest is being transferred in compliance
      with Regulation S under the Securities Act;

     

    (iii)  if
      such
      beneficial interest in such Unrestricted Global Security is being transferred
      in
      compliance with any other exemption from registration under the Securities
      Act,
      certification to that effect from such Holder (in substantially the form set
      forth in Exhibit A) and if the Company or the Trustee so requests, an Opinion
      of
      Counsel, certificates and other information reasonably acceptable to the Company
      to the effect that such transfer does not require registration under the
      Securities Act; or

     

    (iv)  a
      certification (in substantially the form set forth in Exhibit A) to the effect
      that such beneficial interest is being transferred to the Company or a
      Subsidiary of the Company, the Registrar shall reduce or cause to be reduced
      the
      aggregate principal amount of the Unrestricted Global Security by the
      appropriate principal amount and shall increase or cause to be increased the
      aggregate principal amount of the Restricted Global Security by a like principal
      amount. Such transfer shall otherwise be effected in accordance with the
      Applicable Procedures. If no Restricted Global Security is then outstanding,
      the
      Company shall execute and the Trustee shall, upon receipt of a Company Order
      (which the Company agrees to deliver promptly), authenticate and deliver a
      Restricted Global Security.

     

    (e)  Transfers
      of Certificated Securities for Beneficial Interest in Global
      Securities.
      In the
      event that Certificated Securities are issued in exchange for beneficial
      interests in Global Securities and, thereafter, the events or conditions
      specified in Section 2.12(a)(i) which required such exchange shall cease to
      exist, the Company shall mail notice to the Trustee and to the Holders
(i)
      stating
      that Holders may exchange Certificated Securities for interests in Global
      Securities by complying with the procedures set forth in this Indenture and
      (ii)
      briefly
      describing such procedures and the events or circumstances requiring that such
      notice be given. Thereafter, if Certificated Securities are presented by a
      Holder to a Registrar with a request:

     

    (x) to
      register the transfer of such Certificated Securities to a Person who will
      take
      delivery thereof in the form of a beneficial interest in a Global Security,
      which request shall specify whether such Global Security will be a Restricted
      Global Security or an Unrestricted Global Security; or

     

    (y) to
      exchange such Certificated Securities for an equal principal amount of
      beneficial interests in a Global Security, which beneficial interests will
      be
      owned by the Holder transferring such Certificated Securities (provided that
      in
      the case of such an exchange, Restricted Certificated Securities may be
      exchanged only for Restricted Global Securities and Unrestricted Certificated
      Securities may be exchanged only for Unrestricted Global
      Securities),

     

    the
      Registrar shall register the transfer or make the exchange as requested by
      canceling such Certificated Security and causing the aggregate principal amount
      of the applicable Global Security to be increased accordingly and, if no such
      Global Security is then outstanding, the Company shall issue and the Trustee
      shall, upon receipt of a Company Order (which the Company agrees to deliver
      promptly) authenticate and deliver a new Global Security; provided,
      however,
      that

    (f)  Legends.
      (i)
      Except
      as permitted by the following paragraphs (ii), (iii) and (iv), each Global
      Security and Certificated Security (and all Securities issued in exchange
      therefor or upon registration of transfer or replacement thereof) shall bear
      a
      legend in substantially the form called for by Exhibit A attached hereto (the
      “Restricted
      Legend”),
      for
      so long as it is required by this Indenture to bear such legend.

     

    (ii)  Upon
      any
      sale or transfer of a Restricted Security (x) after the expiration of the
      holding period applicable to sales of the Securities under Rule 144(k) of the
      Securities Act, (y) pursuant to Rule 144 or (z) pursuant to an effective
      registration statement under the Securities Act:

     

    (A)  in
      the
      case of any Restricted Certificated Security, each Registrar shall permit the
      Holder thereof to transfer such Restricted Certificated Security to a transferee
      who, unless such transferee is an Affiliate of the Company, shall take such
      Security in the form of an Unrestricted Certificated Security or (under the
      circumstances described in Section 2.12(e)) an Unrestricted Global Security,
      and
      in each case shall rescind any restriction on the transfer of such Security;
      provided,
      however,
      that
      the Holder of such Restricted Certificated Security shall, in connection with
      such exchange or transfer, comply with the other applicable provisions of this
      Section 2.12; and

     

    (B)  in
      the
      case of a Restricted Global Security, each Registrar shall permit the Holder
      thereof to transfer such beneficial interest in a Restricted Global Security
      to
      a transferee who, unless such transferee is an Affiliate of the Company, shall
      take such Security in the form of a beneficial interest in an Unrestricted
      Global Security and shall rescind any restriction on transfer of such Security;
      provided,
      however,
      that
      such Unrestricted Global Security shall continue to be subject to the provisions
      of Section 2.12(a)(ii); and provided further,
      however,
      that
      the owner of such beneficial interest shall, in connection with such transfer,
      comply with the other applicable provisions of this Section 2.12.

     

    If
      the
      Applicable Procedures so require, prior to the removal of any restrictive legend
      at the end of the holding period applicable to sales of the Securities under
      Rule 144(k) of the Securities Act, such requesting Holder shall deliver an
      Opinion of Counsel in form reasonably acceptable to the Company to the effect
      that the restrictions on transfer contained herein and the restrictive legend
      are no longer required in order to maintain compliance with the Securities
      Act.

    (iii)  Upon
      the
      exchange, registration of transfer or replacement of Securities not bearing
      the
      Restricted Legend, the Company shall issue, and the Trustee shall, upon receipt
      of a Company Order (which the Company agrees to deliver promptly), authenticate
      and deliver, Securities that do not bear such Restricted Legend.

     

    (iv)  After
      the
      expiration of the holding period pursuant to Rule 144(k) of the Securities
      Act,
      the Company may with the consent of any Holder of a Restricted Global Security
      or a Restricted Certificated Security that is not an Affiliate of the Company,
      remove any restriction of transfer on such Security, and the Company shall
      issue, and the Trustee shall, upon receipt of a Company Order (which the Company
      agrees to deliver promptly), authenticate and deliver Securities that do not
      bear the Restricted Legend.

     

    (v)  Until
      the
      expiration of the holding period applicable to sales of the Securities under
      Rule 144(k) of the Securities Act or a transfer pursuant to Rule 144 or pursuant
      to an effective registration statement under the Securities Act, the shares
      of
      Common Stock issued upon conversion of the Securities shall bear a legend
      substantially to the same effect as the Restricted Legend; provided
      that all
      Securities held by Affiliates of the Company shall bear the Restricted Legend
      at
      all times.

     

    (g)  Transfers
      to the Company.
      Nothing
      contained in this Indenture or in the Securities shall prohibit the sale or
      other transfer of any Securities (including beneficial interests in Global
      Securities) to the Company, or any of its Subsidiaries or any of its
      Affiliates.

     

    Section
      2.13   CUSIP
      Numbers.

     

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

     

    Section
      2.14   Persons
      Deemed Owners.

     

    Prior
      to
      due presentment of a Security for registration of transfer, the Company, the
      Trustee and any agent of the Company or the Trustee may treat the person in
      whose name such Security is registered, which shall initially be the Depositary,
      as the owner of such Security for the purpose of receiving payment of principal
      of, the Repurchase Price, the Fundamental Change Purchase Price and interest
      (including Contingent Interest or Additional Interest, if any), on the Security,
      for the purpose of receiving Common Stock or Cash and for all other purposes,
      including without limitation, for purposes of giving notices hereunder,
      whatsoever, whether or not such Security is overdue, and none of the Company,
      the Trustee nor any agent of the Company or the Trustee shall be affected by
      notice to the contrary. The registered Holder of a Global Security may grant
      proxies and otherwise authorize any person, including Agent Members and persons
      that may hold interests through Agent Members, to take any action that a Holder
      is entitled to take under this Indenture or the Securities.

     

    Section
      2.15   Defaulted
      Interest.

     

    If
      the
      Company defaults on a payment of interest (including Contingent Interest or
      Additional Interest, if any) on the Securities, it shall pay the defaulted
      interest, plus (to the extent permitted by law) any interest payable on the
      defaulted interest, in accordance with the terms hereof, to the Persons who
      are
      Holders on a subsequent special record date, which date shall be at least five
      Business Days prior to the payment date. The Company shall fix such special
      record date and payment date in a reasonable manner. At least 10 days before
      such special record date, the Company shall mail to each Holder a notice that
      states the special record date, the payment date and the amount of defaulted
      interest, and interest payable on defaulted interest, if any, to be paid. The
      Company may make payment of any defaulted interest in any other lawful manner
      not inconsistent with the requirements (if applicable) of any securities
      exchange on which the Securities may be listed and, upon such notice as may
      be
      required by such exchange.

    Section
      2.16   Contingent
      Debt Tax Treatment.

     

     (a)  The
      Company and each Holder, by acquiring a beneficial interest in a Security,
      agree
      (in the absence of an administrative pronouncement or judicial ruling to the
      contrary) (i) to treat the Security as indebtedness for U.S. federal income
      tax purposes that is subject to the Treasury Regulations governing contingent
      payment debt instruments (the “contingent
      debt regulations”),
      (ii) that each Holder shall be bound by the Company’s application of the
      contingent debt regulations to the Security, including the Company’s
      determination of the “comparable yield” and “projected payment schedule” within
      the meaning of the contingent debt regulations, (iii) to treat the cash and
      the fair market value of any Common Stock received upon the conversion of the
      Security as a contingent payment for purposes of the contingent debt
      regulations, (iv) to accrue interest with respect to the outstanding
      Security as original issue discount according to the “noncontingent bond method”
set forth in the contingent debt regulations, using the comparable yield of
      7.00% compounded semi-annually and (v) that the Company and each Holder
      will not take any position on any U.S. federal tax return that is inconsistent
      with (i), (ii), (iii) or (iv) unless required by applicable law.

     

    The
      Company acknowledges and agrees, and each Holder and any beneficial holder
      of a
      Security by its purchase thereof shall be deemed to acknowledge and agree,
      that
      (i) the comparable yield means the annual yield the Company would pay, as
      of the Issue Date, on a fixed rate, nonconvertible debt security with no
      contingent payments, but with terms and conditions otherwise comparable to
      those
      of the Securities, (ii) the schedule of projected payments is determined on
      the basis of an assumption of a constant annual growth rate of the stock price
      and is not determined for any purpose other than for the determination of
      interest accruals and adjustments thereof in respect of the Securities for
      U.S.
      federal income tax purposes and (iii) the comparable yield and the schedule
      of projected payments do not constitute a projection or representation regarding
      the amounts payable on the Securities.

     

    A
      Holder
      may obtain the projected payment schedule for the Security, as determined by
      the
      Company pursuant to the contingent debt regulations, by submitting a written
      request to the Company at the following address: Linear Technology Corporation,
      1630 McCarthy Boulevard, Milpitas, CA 95035-7417, Attention: Chief Financial
      Officer.

     

    (b)  Each
      Security shall bear a legend relating to U.S. federal income tax matters in
      the
      form set forth in Exhibit A.

    Redemption
      and Repurchases

     

    Section
      5.01   Company’s
      Right to Redeem; Notices to Trustee.

     

    Prior
      to
      November 1, 2010, the Securities shall not be redeemable at the Company’s
      option. On or after November 1, 2010, the Company, at its option, may redeem
      the
      Securities for Cash at any time, in whole or in part, at a redemption price
      (the
“Redemption
      Price”)
      equal
      to 100% of the principal amount of the Securities being redeemed, plus any
      accrued and unpaid interest (including Contingent Interest or Additional
      Interest, if any) to, but not including, the Redemption Date; provided
      that if
      the Redemption Date falls after an Interest Payment Record Date and prior to
      the
      corresponding Interest Payment Date, accrued and unpaid interest (including
      Contingent Interest or Additional Interest, if any) shall be paid to the Holder
      on the relevant Interest Payment Record Date. If the Company elects to redeem
      Securities pursuant to this Section 5.01, it shall notify the Trustee in writing
      of such election together with the Redemption Date, the Conversion Rate, the
      principal amount of Securities to be redeemed and the Redemption Price.
      Notwithstanding the foregoing, the Company may not redeem the Securities if
      it
      has failed to pay any interest (including Contingent Interest or Additional
      Interest, if any) on the Securities when due and such failure to pay is
      continuing.

     

    The
      Company shall give the notice to the Trustee provided for in this Section 5.01
      by a Company Order, at least 20 days but not more than 60 days before the
      Redemption Date (unless a shorter notice shall be satisfactory to the
      Trustee).

     

    Section
      5.02   Selection
      of Securities to Be Redeemed.

     

    If
      the
      Company decides to redeem fewer than all of the Securities, unless the
      procedures of the Depositary provide otherwise, the Trustee shall select the
      Securities to be redeemed by lot, or in its discretion, on a pro rata basis.
      The
      Trustee may select for redemption portions of the principal amount of Securities
      that have denominations larger than $1,000.

     

    Securities
      and portions of Securities that the Trustee selects shall be in principal
      amounts of $1,000 or an integral multiple of $1,000. Provisions of this
      Indenture that apply to Securities called for redemption also apply to portions
      of Securities called for redemption. The Trustee shall notify the Company
      promptly (but in any case within seven days of the Company Order referred to
      in
      Section 5.01 unless a shorter notice is acceptable to the Company) of the
      Securities or portions of the Securities selected to be redeemed and, in the
      case of any Securities selected for partial redemption, the method it has chosen
      for the selection of the Security.

     

    Following
      a notice of redemption, Securities and portions of Securities are convertible,
      pursuant to Section 7.01(b)(iii), by the Holder until the Close of Business
      on the Business Day prior to the Redemption Date. If any Security selected
      for
      partial redemption is converted in part before termination of the conversion
      right with respect to the portion of the Security so selected, the converted
      portion of such Security shall be deemed (so far as may be) to be the portion
      selected for redemption. Securities that have been converted during a selection
      of Securities to be redeemed may be treated by the Trustee as outstanding for
      the purpose of such selection.

     

    Section
      5.03   Notice
      of Redemption.

     

    At
      least
      20 days but no more than 60 days before a Redemption Date, the Company shall
      mail a notice of redemption (substantially in the form set forth in Exhibit
      A)
      by first-class mail, postage prepaid, to each Holder of Securities to be
      redeemed.

     

    The
      notice shall identify the Securities to be redeemed and shall state (along
      with
      any other information the Company wishes to include):

     

    (a)  the
      Redemption Date;

     

    (b)  the
      Redemption Price;

     

    (c)  the
      Conversion Rate;

     

    (d)  the
      name
      and address of the Paying Agent and Conversion Agent;

     

    
      
        
        

      

      
        23

        
          

        

      

      
        
        

      

    

    (e)  that
      Securities may be converted at any time before the Close of Business on the
      Business Day prior to the Redemption Date;

     

    (f)  that
      Securities called for redemption and not converted shall be redeemed on the
      Redemption Date;

     

    (g)  that
      Holders who want to convert their Securities must satisfy the requirements
      set
      forth in the Securities;

     

    (h)  that
      Securities called for redemption must be surrendered to the Paying Agent (by
      effecting book entry transfer of the Securities or delivering Certificated
      Securities, together with necessary endorsements, as the case may be) to collect
      the Redemption Price;

     

    (i)  if
      fewer
      than all of the outstanding Securities are to be redeemed, the certificate
      numbers, if any, and principal amounts of the particular Securities to be
      redeemed;

     

    (j)  that,
      unless the Company defaults in making payments of such Redemption Price,
      interest, including Contingent Interest, if any, and Additional Interest, if
      any, on the Securities called for redemption shall cease to accrue from and
      after the Redemption Date; and

     

    (k)  the
      CUSIP, “ISIN” or other similar number(s), as the case may be, of the Securities
      being redeemed.

     

    At
      the
      Company’s request, the Trustee shall give the notice of redemption in the
      Company’s name and at the Company’s expense, provided
      that the
      Company makes such request at least seven Business Days (or such shorter period
      as may be satisfactory to the Trustee) prior to the date by which such notice
      of
      redemption must be given to Holders in accordance with this
      Section 5.03.

     

    Section
      5.04   Effect
      of Notice of Redemption.

     

    Once
      notice of redemption is given, Securities called for redemption become due
      and
      payable on the Redemption Date and at the Redemption Price stated in the notice
      except for Securities that are converted in accordance with the terms of this
      Indenture. Upon surrender to the Paying Agent, such Securities shall be paid
      at
      the Redemption Price stated in the notice and from and after the Redemption
      Date
      (unless the Company shall default in the payment of the Redemption Price) such
      Securities shall cease to bear interest (including Contingent Interest or
      Additional Interest, if any) and the rights of the Holders therein shall
      terminate (other than the right to receive the Redemption Price).

      of Redemption Price.

     

    Prior
      to
      10:00 a.m. (New York City time), on the Redemption Date, the Company shall
      deposit with the Paying Agent (or if the Company or a Subsidiary or an Affiliate
      of either of them is the Paying Agent, shall segregate and hold in trust) money
      sufficient to pay the Redemption Price of all Securities to be redeemed on
      that
      date other than Securities or portions of Securities called for redemption
      which
      on or prior thereto have been delivered by the Company to the Trustee for
      cancellation or have been converted. Upon written request of the Company, the
      Paying Agent shall as promptly as practicable return to the Company any money
      not required for that purpose because of conversion of Securities pursuant
      to
      Article 7. If such money is then held by the Company or a Subsidiary or an
      Affiliate of either in trust and is not required for such purpose it shall
      be
      discharged from such trust.

    (a)
      On

      record on the corresponding Interest Payment Record Date. Not later than 20

      terms of the Securities if the applicable Repurchase Notice has been withdrawn
      in accordance with the terms of this Indenture;

     

    (iv)
      that
      Securities must be surrendered to the Paying Agent (by effecting book entry

      with
      necessary endorsements, as the case may be) to collect
      payment;

     

    (v)that
      the
      Repurchase Price for any security as to which a Repurchase Notice has been
      given
      and not withdrawn shall be paid promptly following the later of the Business
      Day
      immediately following the Repurchase Date and the time of surrender of such
      Security as described in clause (iv) above;

    (x)the
      CUSIP, “ISIN” or other similar number(s), as the case may be, of the

    (xi)that
      any
      Security not properly tendered or otherwise not accepted for repurchase shall
      remain outstanding and continue to accrue interest, Contingent Interest, if
      any,

    (xii)that,
      in
      order to withdraw any Repurchase Notice previously delivered by a Holder to
      the
      Paying Agent, the Holder must deliver to the Paying Agent, by 5:00 p.m. (New
      York time) on the day that is the second Business Day prior to the Repurchase
      Date, a written notice of withdrawal specifying (A) the certificate number,
      if
      any, of the Securities in respect of which such notice of withdrawal is being
      submitted, (B) the principal amount of Securities in respect of which such
      notice of withdrawal is being submitted (or if the Securities are not in
      definitive form, the notice of withdrawal must comply with the Applicable
      Procedures), and (C) if the Holder is not withdrawing its Repurchase Notice
      for
      all of its Securities, the principal amount of the Securities which still remain
      subject to the original Repurchase Notice; and

     

    (xiii)that
      Holders whose Securities are being repurchased only in part will be issued
      new
      Securities equal in principal amount to the portion of the Securities tendered
      (or transferred by book-entry transfer) that is not to be repurchased, which
      portion must be equal to $1,000 in principal amount or an integral multiple
      thereof.

     

    At
      the
      Company’s request, the Trustee shall give such Company Notice to each Holder in
      the Company’s name and at the Company’s expense; provided,
      however,
      that,
      in all cases, the text of such Company Notice shall be prepared by the
      Company.

     

    (b)A
      Holder
      may exercise its rights specified in Section 5.07(a) upon delivery to the
      Paying Agent of a written notice of repurchase substantially in the form set

      Date, stating:

      transfer;

     

    (ii)the
      portion of the principal amount of the Security which the Holder shall deliver
      to be repurchased, which portion must be in principal amounts of $1,000 or
      an
      integral multiple of $1,000; and

     

    (iii)that
      such
      Security shall be repurchased by the Company as of the Repurchase Date pursuant
      to the terms and conditions specified in Section 6 of the Securities and in
      this
      Indenture.

     

    The
      delivery of such Security (together with all necessary endorsements) to the
      Paying Agent at any time after delivery of the Repurchase Notice at the offices
      of the Paying Agent shall be a condition to receipt by the Holder of the
      Specified Repurchase Price therefor; provided,
      however,
      that
      such Repurchase Price shall be so paid pursuant to this Section 5.07 only if

      5.07,
      a portion of a Security, if the principal amount of such portion is $1,000
      or an
      integral multiple of $1,000. Provisions of this Indenture that apply to the
      repurchase of all of a Security also apply to the repurchase of such portion
      of
      such Security.

     

    Any
      repurchase by the Company contemplated pursuant to the provisions of this
      Section 5.07 shall be consummated by the delivery of the consideration to be
      received by the Holder promptly following the later of the Business Day

      $1,000 or an integral multiple thereof on a date specified by the Company (the
      “Fundamental
      Change Purchase Date”,
      together with the Specified Purchase Dates, the “Repurchase
      Dates”)
      that
      is not less than 15 nor more than 45 Business Days after the date the Company

      a
      purchase price in Cash equal to 100% of the principal amount of the Securities
      tendered for purchase, plus accrued and unpaid interest (including Contingent
      Interest and Additional Interest, if any) on those Securities to, but not

      outstanding classes of the Company’s voting stock or has the power, directly or
      indirectly, to elect a majority of the members of the board of directors of
      the
      Company and (a) such person or group files a Schedule 13D or Schedule TO, or
      any
      successor schedule, form or report under the Exchange Act, disclosing the same
      or (b) the Company otherwise becomes aware of any such person or
      group;

     

    (ii)  the
      Company consolidates with, or merges with or into, another person, or in a
      single transaction or a series of transactions, the Company sells, assigns,
      conveys, transfers, leases or otherwise disposes of all or substantially all
      of
      its assets, or any person consolidates with, or merges with or into, the
      Company, in any such event other than pursuant to a transaction in which the
      persons that “beneficially owned” directly or indirectly, the shares of the
      Company’s voting stock immediately prior to such transaction beneficially own,
      directly or indirectly, shares of voting stock representing a majority of the
      total voting power of all outstanding classes of voting stock of the surviving
      or transferee person in substantially the same proportion amongst themselves
      (disregarding for this purpose any shares of voting stock (a) received as
      consideration for the capital stock of any person other than the Company or
      (b) held prior to such transaction and issued by a person other than the
      Company) as such ownership immediately prior to such transaction;

     

    
      
        
        

      

      
        27

        
          

        

      

      
        
        

      

    

    (iii)  the
      common stock into which the Securities are then convertible ceases to be listed
      on the NYSE, Nasdaq or another national securities exchange and is not then
      quoted on an established automated over-the-counter trading market in the United
      States and no American Depositary Shares or similar instruments for the common
      stock are so listed or quoted in the United States;

     

    (iv)  continuing
      directors cease to constitute a majority of the Company’s board of directors;
      or

     

    (v)  the
      Company’s stockholders approve any plan or proposal for the Company’s
      liquidation or dissolution.

     

    Subject
      to the next succeeding paragraph, “Makewhole
      Fundamental Change”
shall
      be deemed to have occurred upon the occurrence of a Fundamental Change described
      in clauses (i), (ii), and (v) above.

     

    Notwithstanding
      anything to the contrary set forth in this Indenture, a merger or consolidation
      described in clause (ii) above shall be deemed not to constitute a Fundamental
      Change for any purpose under the definition of Fundamental Change if at least
      90% of all the consideration (excluding Cash payments for fractional shares
      and
      Cash payments pursuant to dissenters’ appraisal rights) in the merger or
      consolidation constituting the Fundamental Change consists of common stock
      traded on the NYSE, Nasdaq or another national securities exchange (or which
      shall be so traded when issued or exchanged in connection with such merger
      or
      consolidation) and as a result of such transaction or transactions the
      Securities become convertible solely into Cash in an amount equal to the lesser
      of $1,000 and the Conversion Value and, if the Conversion Value is greater
      than
      $1,000, payment of the excess value in Cash, shares or a combination of Cash
      and
      shares in substantially the same manner as described herein.

      A
      hereto and which may be delivered by letter, overnight courier, hand delivery,
      facsimile transmission or in any other written form and, in the case of Global
      Securities, may be delivered electronically or by other means in accordance
      with
      the Applicable Procedures) of the exercise of such rights (a “Fundamental
      Change Purchase Notice”)
      to and
      actually received by a Paying Agent at any time prior to 5:00 p.m., New York
      City time, on the Business Day immediately preceding the Fundamental Change

    (ii)  the
      portion of the principal amount of the Securities that the Holder shall deliver
      to be purchased, which portion must be in principal amounts of $1,000 or an
      integral multiple thereof; and

    The
      delivery of such Security to any Paying Agent (together with all necessary
      endorsements) at the office of such Paying Agent shall be a condition to the
      receipt by the Holder of the Fundamental Change Purchase Price; provided,
      however,
      that
      such Fundamental Change Purchase Price shall be paid pursuant to this Section
      5.08 only if the Security so delivered to the Paying Agent shall conform in
      all
      material respects to the description thereof in the related Fundamental Change
      Purchase Notice.

     

    The
      Company shall purchase from the Holder thereof, pursuant to this Section 5.08,
      a
      portion of a Security if the principal amount of such portion is $1,000 or
      an
      integral multiple of $1,000. Provisions of this Section 5.08 that apply to
      the
      purchase of all of a Security also apply to the purchase of such a portion
      of
      such Security.

     

    Notwithstanding
      anything herein to the contrary, any Holder delivering to the Paying Agent
      the
      Fundamental Change Purchase Notice contemplated by this Section 5.08(c) shall
      have the right to withdraw such Fundamental Change Purchase Notice at any time
      prior to 5:00 p.m., New York City time, on the Business Day immediately
      preceding the Fundamental Change Purchase Date by delivery of a written notice
      of withdrawal to the Paying Agent in accordance with Section

      Paying
      Agent shall promptly notify the Company once each Business Day of the receipt
      by
      it of any Fundamental Change Purchase Notices or written notices of withdrawal
      thereof.

     

    (d)  Notwithstanding
      anything herein to the contrary, in the case of Global Securities, any
      Fundamental Change Purchase Notice may be delivered or withdrawn, and such
      Securities may be surrendered or delivered for purchase, in accordance with
      the
      Applicable Procedures.

     

    Section
      5.09   Effect
      of Repurchase Notice or Fundamental Change Purchase Notice.

     

     (a)
      Upon
      receipt by any Paying Agent of a Repurchase Notice or a Fundamental Change
      Purchase Notice, the Holder of the Security in respect of which such Repurchase
      Notice or Fundamental Change Purchase Notice, as the case may be, was given
      shall (unless such Repurchase Notice or Fundamental Change Purchase Notice
      is
      withdrawn as specified below) thereafter be entitled to receive the Repurchase
      Price or Fundamental Change Purchase Price, as the case may be, with respect
      to
      such Security. Such Fundamental Change Purchase Price shall be paid to such
      Holder promptly following the later of (i) the Fundamental Change Purchase
      Date
      (provided such Holder has satisfied the conditions in Section 5.08(c)) with
      respect to such Security or Repurchase Date (provided such Holder has satisfied
      the conditions of Section 5.07) with respect to such Security, as the case
      may
      be, and (ii) the time of delivery of such Security to a Paying Agent by the
      Holder thereof in the manner required by Section 5.07 or 5.08(c). A Security
      in
      respect of which a Repurchase Notice or a Fundamental Change Purchase Notice
      has
      been given by the Holder thereof may not be converted pursuant to Article 7
      hereof on or after the date of the delivery of such Repurchase Notice or
      Fundamental Change Purchase Notice, unless either (i) such Repurchase Notice
      or
      Fundamental Change Purchase Notice has first been validly withdrawn in
      accordance with Section 5.09(b); or (ii) there shall be a default in the payment
      of the Repurchase Price or Fundamental Change Purchase Price, provided,
      that
      the conversion right with respect to such Security shall terminate at 5:00
      p.m.,
      New York City time, on the date such default is cured and such Security is
      purchased in accordance herewith.

     

    (b)  A
      Repurchase Notice or Fundamental Change Purchase Notice may be withdrawn by
      any
      Holder delivering such Fundamental Change Purchase Notice upon delivery of
      a
      written notice of withdrawal (which may be delivered by mail, overnight courier,
      hand delivery, facsimile transmission or in any other written form and, in
      the
      case of Global Securities, may be delivered electronically or by other means
      in
      accordance with the Applicable Procedures) to and actually received by Paying
      Agent at any time prior to 5:00 p.m., New York City time, on the second Business
      Day immediately preceding the Repurchase Date or the Business Day immediately
      preceding the Fundamental Change Purchase Date, specifying:

     

    
      
        
        

      

      
        31

        
          

        

      

      
        
        

      

    

    (i)  if
      Certificated Securities are to be withdrawn, the certificate numbers of the
      Securities in respect of which such notice of withdrawal is being
      submitted;

     

    (ii)  the
      principal amount of the Securities in respect of which such notice of withdrawal
      is being submitted, which principal amount must be $1,000 or an integral
      multiple thereof; and

     

    (iii)  the
      principal amount, if any, of the Securities that remains subject to the original
      Repurchase Notice or Fundamental Change Purchase Notice, as the case may be,
      and
      that has been or shall be delivered for purchase by the Company.

     

    Section
      5.10   Deposit
      of Repurchase Price or Fundamental Change Purchase Price.

     

    Prior
      to
      10:00 a.m., New York City time, on a Repurchase Date, the Company shall deposit
      with the Paying Agent (or if the Company or an Affiliate of the Company is
      acting as the Paying Agent, shall segregate and hold in trust as provided in
      Section 2.04) an amount in Cash (in immediately available funds) sufficient
      to
      pay the aggregate Repurchase Price or Fundamental Change Purchase Price, as
      the
      case may be, of all the Securities or portions thereof that are to be purchased
      on that Repurchase Date.

     

    If
      a
      Paying Agent holds, in accordance with the terms hereof, at 10:00 a.m., New
      York
      City time, on a Repurchase Date, Cash sufficient to pay the aggregate Repurchase
      Price or Fundamental Change Purchase Price, as the case may be, of all
      Securities for which a Repurchase Notice or Fundamental Change Purchase Notice
      has been delivered and not validly withdrawn in accordance with this Indenture,
      then, on and after such Repurchase Date, such Securities shall cease to be
      outstanding and interest (including Contingent Interest or Additional Interest,
      if any) on such Securities shall cease to accrue, whether or not such Securities
      are delivered to the Paying Agent, and the rights of the Holders in respect
      thereof shall terminate (other than the right to receive the Repurchase Price
      or
      Fundamental Change Purchase Price, as applicable, upon delivery of such
      Securities by their Holders to the Paying Agent).

     

    Section
      5.11   Securities
      Purchased in Part.

     

    Any
      Certificated Security that is to be purchased only in part shall be surrendered
      at the office of a Paying Agent (with, if the Company or the Trustee so
      requires, due endorsement by, or a written instrument of transfer in form
      reasonably satisfactory to the Company and the Trustee duly executed by, the
      Holder thereof or such Holder’s attorney duly authorized in writing), and
      promptly after a Repurchase Date, the Company shall issue and the Trustee shall,
      upon receipt of a Company Order (which the Company agrees to deliver promptly),
      authenticate and deliver to the Holder of such Security, without service charge,
      a new Security or Securities, of such authorized denomination or denominations
      as may be requested by such Holder, in aggregate principal amount equal to,
      and
      in exchange for, the portion of the principal amount of the Security so
      surrendered that is not purchased.

     

    Section
      5.12   Repayment
      to the Company.

     

    To
      the
      extent that the aggregate amount of Cash deposited by the Company pursuant
      to
      Section 5.10 exceeds the aggregate Repurchase Price or Fundamental Change
      Purchase Price, as the case may be, of the Securities or portions thereof that
      the Company is obligated to purchase on the applicable Repurchase Date, then,
      within one day after the applicable Repurchase Date, the Paying Agent shall
      return any such excess Cash to the Company.

    When
      complying with the provisions of Article 5 hereof and subject to any exemptions
      available under applicable law, the Company shall:

     

    (a)  comply
      with Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange
      Act that may then be applicable; 

     

    (b)  file
      a
      Schedule TO or other successor or similar schedule, if required, under the
      Exchange Act; and

     

    (c)  otherwise
      comply with all federal and state securities laws so as to permit the rights
      and
      obligations in connection with any purchase pursuant to this Article 5 to be
      exercised in the time and in the manner specified herein.

    Conversion

     

    Section
      7.01   Conversion
      Privilege.

     

     (a)
      Subject
      to and upon compliance with the provisions of this Article 7, at the option
      of
      the Holder thereof, any Security, in whole or in part, may be converted into
      the
      Settlement Amount, at a rate (the “Conversion
      Rate”)
      of
      19.8138 shares of Common Stock per $1,000 principal amount of Securities,
      subject to adjustment pursuant to Section 7.05, prior to the Close of Business
      on the Business Day immediately preceding the Maturity Date.

     

    (b)  The
      Securities shall be convertible (i) at any time on or after March 1, 2027
      and prior to the Close of Business on the Business Day immediately preceding
      the
      Maturity Date and (ii) prior to March 1, 2027, only upon the
      occurrence of one of the following events:

     

    (i)  During
      any calendar quarter after the calendar quarter ending June 30, 2007 and only
      during such calendar quarter, if the Closing Price of the Common Stock for
      twenty (20) or more Trading Days in a period of 30 consecutive Trading Days
      ending on the last Trading Day of the preceding calendar quarter is more than
      130% of the Conversion Price on such last Trading Day. Commencing July 1, 2007
      and at the beginning of each calendar quarter thereafter, the Conversion Agent
      shall determine, on the Company’s behalf, whether the Securities are convertible
      as the result of the satisfaction of this condition in the preceding calendar
      quarter and shall promptly notify the Company and the Trustee accordingly.
      The
      Trustee shall, in turn, notify the Holders in each calendar quarter but in
      no
      event later than seven (7) days after the beginning of such calendar
      quarter.

     

    (ii)  During
      any five Business Day period after any five consecutive Trading Day period
      (the
“Measurement
      Period”)
      in
      which the Trading Price per $1,000 principal amount of Securities for each
      day
      of such Measurement Period was less than 98% of the product of the Closing
      Price
      on such date and the Conversion Rate on such date, all as determined by the
      Trustee. The Trustee shall have no obligation to determine the Trading Price
      of
      Securities unless requested by the Company to do so in writing, and the Company
      shall have no obligation to make such request unless a Holder provides the
      Company with reasonable evidence that the Trading Price per $1,000 principal
      amount of Securities would be less than 98% of the product of (a) the Conversion
      Rate of the Securities and (b) the Closing Price at such time, at which time
      the
      Company shall instruct the Trustee to determine the Trading Price of the
      Securities beginning on the next Trading Day and on each successive Trading
      Day
      until the Trading Price per $1,000 principal amount of Securities is greater
      than or equal to 98% of the product of (a) the Conversion Rate of the Securities
      and (b) the Closing Price on such date. If the Trading Price condition set
      forth
      in this Section 7.01(b)(ii) has been met, the Company shall so notify the
      Holders. If, at any time after the Trading Price condition set forth in this
      Section 7.01(b)(ii) has been met, the Trading Price per $1,000 principal amount
      of Securities is greater than or equal to 98% of the product of (a) the
      Conversion Rate of the Securities and (b) the Closing Price on such date, the
      Company shall so notify the Holders.

     

    
      
        
        

      

      
        33

        
          

        

      

      
        
        

      

    

    (iii)  If
      any of
      the Securities are called for redemption pursuant to Section 5.01 at any time
      prior to the Close of Business on the Business Day prior to the Redemption
      Date,
      even if the Securities are not otherwise convertible at such time.

     

    (iv)  If
      the
      Company elects to distribute to all holders of Common Stock:

     

    (A)  certain
      rights (including rights under a stockholder rights plan) or warrants entitling
      them to purchase, for a period expiring within 45 days of the date of issuance,
      shares of Common Stock at less than the average of the Closing Price for the
      five consecutive Trading Day period ending on the Trading Day preceding the
      announcement of such distribution; or

     

    (B)  cash,
      assets, debt securities or certain rights to purchase the Company’s securities,
      which distribution has a per share value exceeding 7.5% of the Closing Price
      of
      the Common Stock on the Trading Day immediately preceding the announcement
      of
      such distribution;

     

    then,
      in
      either case, the Company shall notify the Holders at least 25 Trading Days
      prior
      to the ex-dividend date for such distribution; provided
      that if
      the Company distributes rights pursuant to a stockholder rights plan, it shall
      notify the holders of the Securities on the Business Day after the Company
      is
      required to give notice generally to its stockholders pursuant to such
      stockholder rights plan if such date is less than 25 Trading Days prior to
      the
      date of such distribution. Once the Company has given the notice, Holders may
      surrender their Securities for conversion at any time until the earlier of
      the
      Close of Business on the Business Day prior to the ex-dividend date or the
      Company’s announcement that such distribution will not take place.
      Notwithstanding the foregoing, a Holder may not convert its Securities under
      this Section 7.01(b)(iv) if the Holder participates in such distribution due
      to
      the participation of Holders in such distribution.

     

    (v)  If
      the
      Company is a party to any transaction or an event occurs that constitutes a
      Fundamental Change, a Holder may surrender Securities for conversion at any
      time
      from and after the date which is ten (10) Trading Days prior to the anticipated
      effective date of such Fundamental Change until and including the Trading Day
      prior to the related Fundamental Change Repurchase Date. The Company shall
      give
      notice in writing to all Holders and the Trustee of a Fundamental Change no
      later than ten (10) Trading Days prior to the anticipated effective date of
      the
      Fundamental Change that the Company knows or reasonably should know will occur.
      If the Company does not know, and should not reasonably know, that a Fundamental
      Change will occur until a date that is within ten (10) Trading Days before
      the
      anticipated effective date of such Fundamental Change, the Company shall give
      notice in writing to all Holders and the Trustee of the Fundamental Change
      promptly after the Company has knowledge of such Fundamental Change. The Board
      of Directors shall determine in good faith the anticipated effective date of
      the
      Fundamental Change, and such determination shall be conclusive and binding
      on
      the Holders and shall be publicly announced by the Company not later than two
      Business Days prior to the end of such 10 Trading Day period.

     

    (c)  If
      a
      Holder elects to convert Securities in connection with a Makewhole Fundamental
      Change that has an Effective Date prior to November 1, 2010, the Company shall
      increase the Conversion Rate by an additional number of shares of Common Stock
      (the “Additional
      Shares”)
      set
      forth in Exhibit B. For purposes of this Section 7.01, any conversion occurring
      at a time when the Securities would be convertible in light of the expected
      or
      actual occurrence of a Makewhole Fundamental Change shall be deemed to have
      occurred “in connection” with a Makewhole Fundamental Change to the extent that
      such conversion is effected during the time period specified in Section
      7.01(b)(v) (regardless of whether the provisions of Section 7.01(b) shall apply
      to such conversion).

     

    
      
        
        

      

      
        34

        
          

        

      

      
        
        

      

    

    The
      increase in the Conversion Rate, expressed as a number of Additional Shares
      per
      $1,000 principal amount of Securities, will be determined by the Company by
      reference to the table attached as Exhibit B hereto, based on the date the
      Makewhole Fundamental Change occurs or becomes effective (the “Effective
      Date”)
      and the
      price paid or deemed to be paid per share of Common Stock in the transaction
      constituting the Makewhole Fundamental Change (the “Stock
      Price”);
      provided
      that if
      a Holder of the Common Stock receives only Cash in connection with a Fundamental
      Change described in clause (ii) of the definition thereof contained in Section
      5.08(a), the Stock Price shall be the Cash amount paid per share. In all other
      cases, the Stock Price shall be the average of the Closing Price of the Common
      Stock over the five consecutive Trading Day period ending on the Trading Day
      preceding the Effective Date of the Fundamental Change, provided
      that if
      the Stock Price is between two Stock Price amounts in the table or the Effective
      Date is between two Effective Dates in the table, the Company shall determine
      the increased Conversion Rate by a straight-line interpolation between the
      number of Additional Shares set forth for the next higher and next lower Stock
      Price amounts and the next earliest and next latest Effective Dates, based
      on a
      365 day year, as applicable. The Stock Price set forth in the first column
      of
      the table attached as Exhibit B hereto shall be adjusted as of any date on
      which
      the Conversion Rate is adjusted pursuant to Section 7.05. The adjusted Stock
      Prices shall equal the Stock Prices applicable immediately prior to such
      adjustment, multiplied by a fraction, the numerator of which is the Conversion
      Rate immediately prior to the adjustment giving rise to the Stock Price
      adjustment and the denominator of which is the Conversion Rate as so adjusted.
      The number of Additional Shares shall be adjusted in the same manner as the
      Conversion Rate is adjusted pursuant to Section 7.05. If (1) the Stock Price
      is
      greater than $150.00 per share of Common Stock (subject to adjustment in the
      same manner as the Stock Price), no increase in the Conversion Rate will be
      made, and (2) the Stock Price is less than $36.05 per share (subject to
      adjustment in the same manner as the Stock Price), no increase in the Conversion
      Rate will be made. Notwithstanding the foregoing, in no event will the number
      of
      Additional Shares in connection with a Makewhole Fundamental Change exceed
      7.93
      per $1,000 principal amount of Securities (subject to adjustment in the same
      manner as set forth in Section 7.05).

     

    (d)  If
      the
      Company is required to increase the Conversion Rate in connection with a
      Makewhole Fundamental Change pursuant to clause (c) above, Securities
      surrendered for conversion will be settled as follows (subject in all respects
      to the provisions set forth in Section 7.13):

     

    (i)  If
      the
      last day of the applicable Conversion Reference Period related to Securities
      surrendered for conversion is prior to the third Trading Day preceding the
      anticipated Effective Date of such Makewhole Fundamental Change, the Company
      shall settle such conversion as described in Section 7.13 by delivering the
      amount of consideration due (as described in Section 7.13, based on the
      Conversion Rate without regard to the number of Additional Shares to be added
      to
      the Conversion Rate as provided in clause (c) above) on the third Trading Day
      immediately following the last day of the applicable Conversion Reference
      Period. In addition, if a Makewhole Fundamental Change occurs, as soon as
      practicable following the Effective Date of such Makewhole Fundamental Change,
      the Company shall deliver the increase in such amount of Cash, shares of Common
      Stock or a combination of Cash and shares of Common Stock or Reference Property,
      if any, as the case may be, as if the Conversion Rate had been increased by
      such
      number of Additional Shares during the related Conversion Reference Period
      (and
      based upon the relevant Daily Conversion Value during such Conversion Reference
      Period). If such increased amount results in an increase to the amount of Cash
      to be paid to Holders, the Company shall pay such increase in Cash, and if
      such
      increased Settlement Amount results in an increase to the amount of Cash, shares
      of Common Stock or a combination of Cash and share of Common Stock, at the
      Company’s option, the Company will deliver such increase by delivering Cash,
      shares of Common Stock or a combination of Cash and shares of Common Stock
      or
      Reference Property based on such increase; and

     

    
      
        
        

      

      
        35

        
          

        

      

      
        
        

      

    

    (ii)  If
      the
      last day of the applicable Conversion Reference Period related to the Securities
      surrendered for conversion is on or following the third Trading Day preceding
      the anticipated Effective Date of the Makewhole Fundamental Change, the Company
      shall settle such conversion as described in Section 7.13 (based on the
      Conversion Rate as increased by the Additional Shares as provided in clause
      (c)
      above) on the later to occur of (A) the Effective Date of the transaction
      and (B) the third Trading Day immediately following the last day of the
      applicable Conversion Reference Period.

     

    Section
      7.02   Conversion
      Procedure.

     

     (a)
      The
      right of conversion attaching to any Security may be exercised at any time
      during which conversion is permitted in accordance with Section 7.01 (i) if
      such
      Security is represented by a Global Security, by book-entry transfer to the
      Conversion Agent through the facilities of the Depositary in accordance with
      the
      Applicable Procedures, or (ii) if such Security is represented by a Certificated
      Security, by delivery of such Security at the specified office of the Conversion
      Agent, accompanied, in either case, by: (1) a duly signed and completed
      conversion notice, in the form as set forth on the reverse of Security attached
      hereto as Exhibit A (a “Conversion
      Notice”);
      (2)
      if such Certificated Security has been lost, stolen, destroyed or mutilated,
      a
      notice to the Conversion Agent in accordance with Section 2.07 regarding the
      loss, theft, destruction or mutilation of the Security; (3) appropriate
      endorsements and transfer documents if required by the Conversion Agent; and
      (4)
      payment of any tax or duty, in accordance with Section 7.03, which may be
      payable in respect of any transfer involving the issue or delivery of the Common
      Stock in the name of a Person other than the Holder of the Security. The date
      on
      which the Holder satisfies all of those requirements is the “Conversion
      Date.”
The
      Securities shall be deemed to be converted immediately prior to the Close of
      Business on the Conversion Date. The Company shall deliver to the Holder through
      a Conversion Agent Cash and, if applicable, a certificate for the number of
      whole shares of Common Stock issuable upon the conversion (and Cash in lieu
      of
      any fractional shares pursuant to Section 7.13(h)) on the applicable date
      specified for such delivery in Section 7.13(g) hereof.

     

    (b)  The
      person in whose name the Security is registered shall, if shares of Common
      Stock
      are issuable upon conversion and if the Company so elects to issue all or any
      portion of such shares in lieu of paying Cash, be deemed to be a stockholder
      of
      record on the Conversion Date; provided,
      however,
      that no
      surrender of a Security or satisfaction of the other conditions in Section
      7.02(a) on any date when the stock transfer books of the Company shall be closed
      shall be effective to constitute the person or persons entitled to receive
      the
      shares of Common Stock upon such conversion as the record holder or holders
      of
      such shares of Common Stock on such date, but such surrender shall, provided
      that all such conditions have been satisfied, be effective to constitute the
      person or persons entitled to receive such shares of Common Stock as the record
      holder or holders thereof for all purposes at the Close of Business on the
      next
      succeeding day on which such stock transfer books are open. Upon conversion
      of a
      Security, such person shall no longer be a Holder of such Security. No separate
      payment or adjustment will be made for accrued and unpaid interest (including
      Contingent Interest or Additional Interest, if any) on a converted Security
      or
      for dividends or distributions on shares of Common Stock issued upon conversion
      of a Security. By delivering to the holder the Cash, shares or combination
      of
      Cash and shares of Common Stock issuable upon conversion, together with a cash
      payment in lieu of any fractional shares, the Company will satisfy its
      obligation with respect to the conversion of the Securities. Accordingly, any
      accrued but unpaid interest (including Contingent Interest or Additional
      Interest, if any) will be deemed paid in full upon conversion, rather than
      cancelled, forfeited or extinguished.

     

    
      
        
        

      

      
        36

        
          

        

      

      
        
        

      

    

    (c)  Upon
      surrender of a Security that is converted in part, the Company shall execute,
      and the Trustee shall, upon receipt of a Company Order, authenticate and deliver
      to the Holder, a new Security equal in principal amount of the unconverted
      portion of the Security surrendered.

     

    Section
      7.03   Taxes
      on Conversion.

     

    If
      a
      Holder converts a Security, the Company shall pay any documentary, stamp or
      similar issue or transfer taxes or duties relating to the issuance or delivery
      of shares of Common Stock upon exercise of such conversion rights. However,
      the
      Holder shall pay any tax or duty which may be payable relating to any transfer
      involving the issuance or delivery of shares of Common Stock in a name other
      than the Holder’s name. The Conversion Agent may refuse to deliver the
      certificate representing shares of Common Stock being issued in a name other
      than the Holder’s name until the Conversion Agent receives a sum sufficient to
      pay any tax or duties which will be due because the shares are to be issued
      in a
      name other than the Holder’s name. Nothing herein shall preclude any tax
      withholding required by law or regulation.

     

    Section
      7.04   Company
      to Provide Stock.

     

     (a)
      The
      Company shall, prior to the issuance of any Securities hereunder, and from
      time
      to time as may be necessary, reserve at all times and keep available, free
      from
      preemptive rights, out of its authorized but unissued Common Stock, a sufficient
      number of shares of Common Stock deliverable upon conversion of all of the
      Securities.

     

    (b)  All
      shares of Common Stock that may be issued upon conversion of the Securities
      shall be newly issued shares or shares held in the treasury of the Company,
      shall be duly authorized, validly issued, fully paid and nonassessable and
      shall
      be free of any preemptive rights and free of any lien or adverse
      claim.

     

    (c)  The
      Company shall comply with all applicable securities laws regulating the offer
      and delivery of any Common Stock upon conversion of Securities and, if the
      Common Stock is then listed or quoted on the NYSE, the Nasdaq or any other
      United States national or regional securities exchange or other market, shall
      list or cause to have quoted and keep listed and quoted the shares of Common
      Stock issuable upon conversion of the Notes to the extent permitted or required
      by the rules of such exchange or market; provided,
      however,
      that,
      if the rules of such automated quotation system or exchange permit the Company
      to defer the listing of such Common Stock until the first conversion of the
      Securities into Common Stock in accordance with the provisions of this
      Indenture, the Company covenants to list such Common Stock issuable upon
      conversion of the Securities in accordance with the requirements of such
      automated quotation system or exchange at such time.

     

    Section
      7.05   Adjustment
      of Conversion Rate.

     

    The
      Conversion Rate shall be adjusted from time to time by the Company if any of
      the
      following events occur, except that the Company will not make any adjustment
      if
      Holders of Securities may participate, as a result of holding the Securities,
      in
      the transactions described without having to convert their
      Securities:

     

    (a)  If
      the
      Company, at any time or from time to time while any of the Securities are
      outstanding, issues shares of its Common Stock as a dividend or distribution
      on
      shares of Common Stock, or if the Company effects subdivisions, combinations
      or
      reclassifications in respect of the Common Stock, then the Conversion Rate
      shall
      be adjusted based on the following formula:

     

    
      	
              CR'=CR0
                x
                

            	
              OS'

            
	
              OS0

            

    

    

     

    
      
        
        

      

      
        37

        
          

        

      

      
        
        

      

    

    where

     

    
      	
              CR0

            	
              =

            	
              the
                Conversion Rate in effect immediately prior to the Ex Date of such
                dividend or distribution, or effective date of such subdivision,
                combination or reclassification, as applicable;

            
	
              CR'

            	
              =

            	
              the
                Conversion Rate in effect on and after the Ex Date or effective
                date;

            
	
              OS0

            	
              =

            	
              the
                number of shares of Common Stock outstanding immediately prior the
                Ex Date
                or effective date; and

            
	
              OS'

            	
              =

            	
              the
                number of shares of Common Stock outstanding on and after the Ex
                Date or
                effective date.

            

    

    

     

    Such
      adjustment shall become effective immediately after 9:00 a.m., New York City
      time, on the Business Day following the record date for such dividend or
      distribution, or the date fixed for determination for such subdivision,
      combination or reclassification. The Company will not pay any dividend or make
      any distribution
      on
      shares of Common Stock held in treasury by the Company. If any dividend or
      distribution of the type described in this ‎Section 7.05(a) is declared but not
      so paid or made, or the outstanding shares of Common Stock are not subdivided,
      combined or reclassified,
      as the case may be, the Conversion Rate shall again be adjusted to the
      Conversion Rate which would then be in effect if such dividend, distribution,
      subdivision, combination or reclassification had not been declared.

     

    (b)  If
      the
      Company, at any time or from time to time while any of the Securities are
      outstanding, issues to all holders of its outstanding shares of Common Stock
      any
      rights or warrants entitling them for a period of not more than 45 calendar
      days
      from the issuance date thereof to subscribe for or purchase shares of Common
      Stock at a price per share less than the average of the Closing Price for the
      five consecutive Trading Day period ending on the Business Day immediately
      preceding the date of announcement of such issuance, the Conversion Rate shall
      be adjusted based on the following formula:

     

    
      	
              CR'
                = CR0
                x
                

            	
              OS0
                +
                X

            
	
              OS0
                +
                Y

            

    

    where

     

    
      	
              CR0

            	
              =

            	
              the
                Conversion Rate in effect immediately prior to the Ex Date for such
                issuance; 

            
	
              CR'

            	
              =

            	
              the
                Conversion Rate in effect on and after the Ex Date for such
                issuance;

            
	
              OS0

            	
              =

            	
              the
                number of shares of Common Stock outstanding on and after the Ex
                Date for
                such issuance;

            
	
              X

            	
              =

            	
              the
                total number of shares of Common Stock issuable pursuant to such
                rights or
                warrants; and

            
	
              Y

            	
              =

            	
              the
                number of shares of Common Stock equal to the aggregate price payable
                to
                exercise such rights or warrants divided by the average of the Closing
                Price for the five consecutive Trading Day period ending on the Business
                Day immediately preceding the date of announcement of the issuance
                of such
                rights or warrants.

            

    

    

     

    
      
        
        

      

      
        38

        
          

        

      

      
        
        

      

    

    Such
      adjustment shall be successively made whenever any such rights or warrants
      are
      issued and shall become effective immediately after 9:00 a.m., New York City
      time, on the Business Day following the record date of such issuance. To the
      extent that shares of Common Stock are not delivered pursuant to such rights
      or
      warrants upon the expiration or termination of such rights or warrants, the
      Conversion Rate shall be readjusted to the Conversion Rate which would then
      be
      in effect had the adjustments made upon the issuance of such rights or warrants
      been made on the basis of the delivery of only the number of shares of Common
      Stock actually delivered. In the event that such rights or warrants are not
      so
      issued, the Conversion Rate shall again be adjusted to be the Conversion Rate
      which would then be in effect if the announcement with respect to such rights,
      warrants or convertible securities had not been made.

     

    In
      determining whether any rights or warrants entitle the holders to subscribe
      for
      or purchase shares of Common Stock at less than the average of the Closing
      Price
      for the five consecutive Trading Day period ending on the Business Day
      immediately preceding the date of announcement of such issuance, and in
      determining the aggregate offering price of such shares of Common Stock, there
      shall be taken into account any consideration received by the Company for such
      rights or warrants and any amount payable on exercise thereof, the value of
      such
      consideration, if other than Cash, to be determined in good faith by the Board
      of Directors.

     

    (c)  In
      case
      the Company shall, by dividend or otherwise, distribute to all holders
      of
      its Common Stock shares of any class of capital stock of the Company (other
      than
      distributions of Common Stock covered by ‎Section 7.05(a)), evidences of its
      Indebtedness or other assets or property of the Company (including securities,
      but excluding
      (i)
      dividends and distributions and rights or warrants covered by Section 7.05(a),
      Section 7.05(b) or Section 7.05(e) (for which an adjustment is made to the
      Conversion Rate), (ii) to the extent provided in Section 7.07, rights
      distributed pursuant to a stockholder rights plan and (iii) cash covered by
      Section 7.05(d) (any of such shares of Capital Stock, Indebtedness, Cash or
      other assets or property hereinafter in this Section 7.05(c) called the
“Distributed
      Property”),
      then,
      in each such case the Conversion Rate shall be adjusted based on the following
      formula:

     

    
      	
              CR'
                = CR0
                x
                

            	
              SP0

            
	
              SP0
                -
                FMV

            

    

    where

     

    
      	
              CR0

    Such
      adjustment shall become effective immediately prior to 9:00 a.m., New York
      City
      time, on the Business Day following the date fixed for the determination of
      stockholders entitled to receive such distribution; provided
      that if
      the then fair market value (as so determined) of the portion of the Distributed
      Property so distributed applicable to one share of Common Stock is equal to
      or
      greater than SP0
      as set
      forth above, in lieu of the foregoing adjustment, adequate provision shall
      be
      made so that each Holder shall have the right to receive, for each $1,000
      principal amount of Securities upon conversion, the amount of Distributed
      Property such holder would have received had such holder owned a number of
      shares of Common Stock equal to the Conversion Rate on the record date. If
      such
      dividend or distribution is not so paid or made, the Conversion Rate shall
      again
      be adjusted to be the Conversion Rate that would then be in effect if such
      record date had not been fixed. If the Board of Directors determines the fair
      market value of any distribution for
      purposes of this ‎Section 7.05(c) by reference to the actual or when issued
      trading market for any securities, it shall in doing so consider the prices
      in
      such market over the same period used in computing the average of the Closing
      Price of the Common Stock.

     

    With
      respect to an adjustment pursuant to this Section 7.05(c) where there has been
      a
      payment of a dividend or other distribution on the Common Stock consisting
      of
      shares of capital stock of any class or series, or similar equity interest,
      of
      or relating to a Subsidiary or other business unit (a “Spin-Off,”

      on
      the fifteenth Trading Day immediately following, and including, the Ex Date
      for
      the distribution of the Spin-Off Securities shall be increased based on the

                share of
                Common Stock over the first 10 consecutive Trading Day period commencing
                on, and including, the fifth Trading Day after the Ex Date for such

                Day

                distribution.

            

    

    

     

    Such
      adjustment shall occur at the Close of Business on the fifteenth Trading Day
      from, and including, the Ex Date for the distribution of the Spin-Off
      Securities; provided, however, that the Company may in lieu of the foregoing
      adjustment elect to make adequate provision so that each Holder of Securities
      shall have the right to receive upon conversion thereof the amount of such
      Spin-Off Securities that such Holder of Securities would have received if such
      Securities had been converted on the record date with respect to such
      distribution.

    Rights
      or
      warrants distributed by the Company to all holders of Common Stock entitling
      the
      holders thereof to subscribe for, purchase or convert into shares of the
      Company’s capital stock (either initially or under certain circumstances), which
      rights or warrants, until the occurrence of a specified event or events
      (“Trigger
      Event”):
      (x)
      are deemed to be transferred
      with such shares of Common Stock; (y) are not exercisable; and (z) are also
      issued in respect of future issuances of Common Stock, shall be deemed not
      to
      have been distributed for purposes of this ‎Section 7.05(b), (and no adjustment
      to the Conversion Rate under this ‎‎Section 7.05(b), will be required) until the
      occurrence of the earliest Trigger Event, whereupon such rights or warrants
      shall be deemed to have been distributed and an appropriate adjustment (if
      any
      is required) to the Conversion Rate shall be made under this ‎Section 7.05(b).
      If any such right or warrant, including any such existing rights or warrants
      distributed prior to the date of this Indenture, are subject to events, upon
      the
      occurrence of which such rights or warrants become exercisable
      to purchase different securities, evidences of Indebtedness or other assets,
      then the date of the occurrence of any and each such event shall be deemed
      to be
      the date of distribution and record date with respect to new rights or warrants
      with such rights (and a termination or expiration of the existing rights or
      warrants without exercise by any of the holders thereof). In addition, in the
      event of any distribution (or deemed distribution) of rights or warrants or
      any
      Trigger Event or other event (of the type described in the preceding sentence)
      with respect thereto that was counted for purposes of calculating a distribution
      amount for which an adjustment to the Conversion Rate under this Section 7.05(b)
      was made, (1) in the case of any such rights or warrants that shall all have
      been redeemed or repurchased without exercise by any holders thereof, the
      Conversion Rate shall be readjusted upon such final redemption or repurchase
      to
      give effect to such distribution or Trigger Event, as the case may be, as though
      it were a cash distribution, equal to the per share redemption or repurchase
      price received by a holder or holders of Common Stock with respect to such
      rights or warrants (assuming such holder had retained such rights or warrants),
      made to all holders of Common Stock as of the date of such redemption or
      repurchase, and (2) in the case of such rights or warrants that shall have
      expired or been terminated without exercise by any holders thereof, the
      Conversion Rate shall be readjusted as if such rights or warrants had not been
      issued.

     

    For
      purposes of this Section 7.05(c), Section 7.05(a) and Section 7.05(b), any
      dividend or distribution to which this Section 7.05(c) is applicable that also
      includes shares of Common Stock, or rights or warrants to subscribe for or
      purchase shares of Common Stock to which Section 7.05(a) or 7.05(b) applies
      (or
      both), shall be deemed instead to be (1) a dividend or distribution of the
      evidences of Indebtedness, assets or shares of capital stock other than such
      shares of Common Stock or rights or warrants to which Section 7.05(a) or 7.05(b)
      applies (and any Conversion Rate adjustment required by this Section 7.05(c)
      with respect to such dividend or distribution shall then be made) immediately
      followed by (2) a dividend or distribution of such shares of Common Stock or
      such rights or warrants to which Section 7.05(a) or 7.05(b) applies (and any
      further Conversion Rate adjustment required by Section 7.05(a) and 7.05(b)
      with
      respect to such dividend or distribution shall then be made), except (A) the
      Ex
      Date of such dividend or distribution shall be substituted for “the Ex Date,”
“the Ex Date or effective date,” “the day following the record date for such
      dividend or distribution, or the date fixed for determination for such
      subdivision, combination or reclassification,” “the Ex Date for such issuance”
and “the date fixed for the determination of stockholders entitled to receive
      such rights and warrants” within the meaning of Section 7.05(a) and Section
      7.05(b) and (B) any shares of Common Stock included in such dividend or
      distribution shall not be deemed “outstanding immediately prior to the Ex Date
      or effective date” within the meaning of Section 7.05(a).

    (d)  If
      a cash
      dividend or distribution is made to all holders of Common Stock (other than
      (i)
      in connection with the Company’s liquidation, dissolution or winding up or (ii)
      distributions described in Section 7.05(e)), the Conversion Rate shall be
      adjusted based on the following formula:

     

    
      	
              CR'
                = CR0

                C

            

    

    where

     

    
      	
              CR0

            	
              =

            	
              the
                Conversion Rate in effect at the Close of Business on the Business
                Day
                immediately prior to the Ex Date for such dividend or
                distribution;

            
	
              CR'

            	
              =

            	
              the
                Conversion Rate in effect on and after the Ex Date for such
                distribution;

            
	
              SP0

            	
              =

            	
              the
                average Closing Price of the Common Stock for the five consecutive
                Trading
                Day period ending on the Trading Day immediately preceding the Ex
                Date for
                such dividend or distribution; and

            
	
              C

            	
              =

            	
              the
                amount in cash per share of Common Stock the Company dividends or
                distributes to holders of Common
                Stock.

            

    

    

     

    Such
      adjustment shall become effective immediately prior to the opening of business
      on the Ex Date for such dividend or distribution; provided that if the portion
      of the cash so distributed applicable to one share of Common Stock is equal
      to
      or greater than SP0
      as set
      forth above, in lieu of the foregoing adjustment, adequate provision shall
      be
      made so that each Holder shall have the right to receive, for each $1,000
      principal amount of Securities upon conversion, the amount of cash such Holder
      would have received had such Holder owned a number of shares of Common Stock
      equal to the Conversion Rate on the record date for such dividend or
      distribution. If such dividend or distribution is not so paid or made, the
      Conversion Rate shall again be adjusted to be the Conversion Rate that would
      then be in effect if such dividend or distribution had not been
      declared.

     

    For
      the
      avoidance of doubt, for purposes of this ‎Section 7.05(d), in the event of any
      reclassification of the Common Stock, as a result of which the Securities become
      convertible into more than one class of Common Stock, if an adjustment to the
      Conversion Rate is required pursuant to this ‎Section 7.05(d), references in
      this Section to one share of Common Stock or Closing Price of one share of
      Common Stock shall be deemed to refer to a unit or to the price of a unit
      consisting of the number of shares of each
      class
      of Common Stock into which the Securities are then convertible equal to the
      numbers of shares of such class issued in respect of one share of Common Stock
      in such reclassification. The above provisions of this paragraph shall similarly
      apply to successive reclassifications.

     

    (e)  If
      the
      Company or any of its Subsidiaries makes a payment in respect of a tender offer
      or exchange offer for all or any portion of the Common Stock, to the extent
      that
      the cash and value of any other consideration included in the payment per share
      of Common Stock validly tendered or exchanged exceeds the Closing Price of
      the
      Common Stock on the Trading Day next succeeding the last date on which tenders
      or exchanges may be made pursuant to such tender or exchange offer (as it may
      be
      amended), the Conversion Rate shall be increased based on the following
      formula:

                purchased in such tender or exchange offer;

    The
      adjustment to the Conversion Rate under this Section 7.05(e) shall occur on
      the
      Trading Day from, and including, the Trading Day next succeeding the date such
      tender or exchange offer expires.

     

    If
      the
      Company is obligated to repurchase shares pursuant to any such tender or
      exchange offer, but the Company is permanently prevented by applicable law
      from
      effecting any such purchases or all or any portion of such purchases are
      rescinded, the Conversion Rate shall again be adjusted to be the Conversion
      Rate
      that would then be in effect if such tender or exchange offer had not been
      made
      or had only been made in respect of the purchases that had been
      effected.

     

    (f)  For
      purposes of this Section 7.05 the term “record
      date”
shall
      mean, with respect to any dividend, distribution or other transaction or event
      in which the holders of Common Stock have the right to receive any cash,
      securities or other property or in which the Common Stock (or other applicable
      security) is exchanged for or converted into any combination of cash, securities
      or other property, the date fixed for determination of stockholders entitled
      to
      receive such cash, securities or other property (whether such date is fixed
      by
      the Board of Directors or by statute, contract or otherwise).

     

    (g)  If
      application of the formulas provided in Sections 7.05(a), 7.05(b), 7.05(c),
      7.05(d) or 7.05(e) would result in a decrease in the Conversion Rate, no
      adjustment to the Conversion Rate shall be made except in the case of a
      subdivision or split of the Common Stock.

     

    
      
        
        

      

      
        43

        
          

        

      

      
        
        

      

    

    (h)  In
      any
      case in which this Section 7.05 shall require that an adjustment be made
      following a record date or Expiration Date, as the case may be, established
      for
      purposes of this Section 7.05, the Company may elect to defer (but only until
      five Business Days following the filing by the Company with the Trustee of
      the
      certificate described in Section 7.10) issuing to the Holder of any Security
      converted after such record date or Expiration Date the shares of Common Stock
      and other capital stock of the Company, evidences of indebtedness or other
      non-Cash assets or rights or warrants issuable upon such conversion over and
      above Cash payable, or the shares of Common Stock and other capital stock of
      the
      Company, evidences of indebtedness or other non-Cash assets or rights or
      warrants issuable, upon such conversion only on the basis of the Conversion
      Rate
      prior to adjustment; and, in lieu of the shares, evidences of indebtedness
      or
      other non-Cash assets or rights or warrants the issuance of which, or Cash
      the
      payment of which, is so deferred, the Company shall issue or cause its transfer
      agents to issue due bills or other appropriate evidence prepared by the Company
      of the right to receive such shares or Cash, as the case may be. If any
      distribution in respect of which an adjustment to the Conversion Rate is
      required to be made as of the record date or Expiration Date therefor is not
      thereafter made or paid by the Company for any reason, the Conversion Rate
      shall
      be readjusted to the Conversion Rate which would then be in effect if such
      record date had not been fixed or such effective date or Expiration Date had
      not
      occurred.

     

    (i)  In
      the
      event of any adjustment to the Conversion Rate pursuant to clauses (b), (c),
      (d)
      and (e) above or as the result of or in connection with a Makewhole Fundamental
      Change pursuant to Section 7.01(c) that would or could reasonably be expected
      to
      result in the Securities, in the aggregate, becoming convertible into shares
      of
      Common Stock in excess of limits established by Nasdaq that would require
      stockholder approval of the issuances of such shares of Common Stock upon such
      conversion, the Company will, at its option, either obtain stockholder approval
      of such issuances or deliver cash in lieu of any shares otherwise deliverable
      upon conversions in excess of such limitations (based on the Closing Price
      of
      the Common Stock on the Trading Day immediately prior to the date when such
      shares would otherwise be required to be distributed).

     

    (j)  If
      one or
      more events occur requiring an adjustment be made to the Conversion Rate for
      a
      particular period, adjustments to the Conversion Rate shall be determined by
      the
      Company’s Board of Directors to reflect the combined impact of such Conversion
      Rate adjustments, as set out in this Section 7.05, during such
      period.

     

    Section
      7.06   No
      Adjustment.

     

    No
      adjustment in the Conversion Rate shall be required unless the adjustment would
      result in a change in the Conversion Rate of at least 1.00%; provided,
      however,
      that
      any adjustment which by reason of this Section 7.06 is not required to be made
      shall be carried forward and taken into account in subsequent adjustments and
      in
      connection with any conversion of Securities. All calculations under this
      Article 7 shall be made to the nearest one-ten thousandth (1/10,000) of a cent
      or to the nearest one-ten thousandth (1/10,000) of a share, as the case may
      be.

     

    No
      adjustment in the Conversion Rate need be made for (i) issuances of Common
      Stock
      pursuant to any present or future Company plan for reinvestment of dividends
      or
      interest payable on the Company’s securities or the investment of additional
      optional amounts thereunder in shares of Common Stock, (ii) upon the issuance
      of
      any shares of Common Stock or options or rights to purchase shares of Common
      Stock pursuant to any present or future employee, director or consultant benefit
      plan or program of or assumed by the Company or any of its subsidiaries or
      (iii)
      upon the issuance of any shares of Common Stock pursuant to any option, warrant,
      right or exercisable, exchangeable or convertible security not described in
      clause (i) or (ii) and outstanding as of the date the Securities were first
      issued.

     

    To
      the
      extent that the Securities become convertible into the right to receive Cash,
      interest will not accrue on such Cash.

     

    
      
        
        

      

      
        44

        
          

        

      

      
        
        

      

    

    No
      adjustment to the Conversion Rate need be made pursuant to Section 7.05 for
      a
      transaction if Holders are permitted to participate in the transaction without
      conversion on a basis and with notice that the Board of Directors of the Company
      determines in good faith to be fair and appropriate in light of the basis and
      notice on which holders of Common Stock participate in the
      transaction.

     

    No
      adjustment to the Conversion Rate need be made for accrued and unpaid interest,
      including Contingent Interest or Additional Interest, if any.

     

    Whenever
      a provision of this Indenture requires the calculation of an average of the
      Closing Price or Volume-Weighted Average Price over a span of multiple days,
      the
      Company shall make appropriate adjustments to account for any adjustment to
      the
      Conversion Rate that becomes effective, or any event requiring an adjustment
      to
      the Conversion Rate that becomes effective, or any event requiring an adjustment
      to the Conversion Rate where the Ex Date of the event occurs, at any time during
      the period from which the average is to be calculated.

     

    Section
      7.07   Stockholder
      Rights Plans.

     

    Upon
      conversion of the Securities, the Holders shall receive, in addition to any
      shares of Common Stock issuable upon such conversion, any associated rights
      issued under any future stockholder rights plan the Company adopts that provides
      each share of Common Stock issued upon conversion of the Securities at any
      time
      prior to the distribution of separate rights certificates representing such
      rights will be entitled to receive such rights unless, prior to conversion,
      the
      rights have separated from the Common Stock, expired, terminated or been
      redeemed or exchanged in accordance with such rights plan, and no adjustment
      shall be made to the Conversion Rate pursuant to Section 7.05. If the rights
      have separated from the Common Stock prior to any conversion, the Conversion
      Rate shall be adjusted at the time of separation as if the Company distributed
      to all holders of Common Stock, shares of Capital Stock, evidences of
      Indebtedness or assets as described in Section 7.05(c), subject to readjustment
      in the event of the expiration, termination or redemption of such
      rights.

     

    Section
      7.08   Effect
      of Reclassification, Consolidation, Merger or Sale on Conversion
      Privilege.

     

    If
      (1)
      there shall occur (a) any reclassification of the Company’s Common Stock (other
      than a change in par value, or from par value to no par value, or from no par
      value to par value, or as a result of a subdivision or combination); (b) a
      statutory share exchange, consolidation, merger or combination involving the
      Company other than a merger in which the Company is the continuing corporation
      and which does not result in any reclassification of, or change (other than
      in
      par value, or from par value to no par value, or from no par value to par value,
      or as a result of a subdivision or combination) in, outstanding shares of Common
      Stock; or (c) a sale or conveyance as an entirety or substantially as an
      entirety of the property and assets of the Company, directly or indirectly,
      to
      another Person; and (2) pursuant to such reclassification, statutory share
      exchange, consolidation, merger, combination, sale or conveyance, holders of
      outstanding shares of Common Stock would be entitled to receive stock (other
      than Common Stock), other securities, other property, assets or Cash for such
      shares of Common Stock (any such event a “Merger
      Event”),
      then
      the Company, or such successor or surviving, purchasing or transferee Person,
      as
      the case may be, shall, as a condition precedent to such Merger Event, execute
      and deliver to the Trustee a supplemental indenture providing that the right
      to
      convert a Security will be changed into a right to convert it into the kind
      and
      amount of shares of stock, other securities or other property or assets
      (including Cash or any combination thereof) that a holder of a number of shares
      of Common Stock equal to the Conversion Rate immediately prior to such Merger
      Event would have owned or been entitled to receive (the “Reference
      Property”)
      upon
      such transaction (assuming for such purposes that such conversion were settled
      entirely in Common Stock and without giving effect to any adjustment to the
      Conversion Rate with respect to a Makewhole Fundamental Change) immediately
      prior to such Merger Event, except that such Holders shall not be entitled
      to
      receive Additional Shares with respect to such transaction constituting a
      Makewhole Fundamental Change if such Holder does not convert its Securities
“in
      connection with” the relevant Fundamental Change. Appropriate provisions shall
      be made, as determined in good faith by the Board of Directors, to preserve
      the
      net share settlement provisions of the Securities described in Section 7.13
      following such Merger Event to the extent feasible. If the Merger Event causes
      the Common Stock to be converted into the right to receive more than a single
      type of consideration (determined based in part upon any form of stockholder
      election), the Reference Property into which the Securities will be convertible
      will be deemed to be the weighted average of the types and amounts of
      consideration received by the holders of Common Stock that affirmatively make
      such an election. However, at and after the effective time of the Merger Event,
      any amount otherwise payable in Cash upon conversion of the Securities shall
      continue to be payable in Cash, and the Daily Conversion Value shall be
      calculated based on the value of the Reference Property. None of the foregoing
      provisions shall affect the right of a holder of Securities to convert its
      Securities in accordance with the provisions of this Article 7 prior to the
      effective date of such Merger Event. Such supplemental indenture shall provide
      for adjustments of the Conversion Rate which shall be as nearly equivalent
      as
      may be practicable to the adjustments of the Conversion Rate provided for in
      this Article 7. The provisions of this Section 7.08 shall similarly apply to
      successive Merger Events.

    Section
      7.09   Other
      Adjustments.

     

    Subject
      to applicable stock exchange rules and listing standards, the Company shall
      be
      entitled to increase the Conversion Rate by any amount for a period of at least
      20 days if the Board of Directors determines that such increase would be in
      the
      best interests in the Company, provided
      the
      Company has given to Holders at least 15 days’ prior notice, in accordance with
      Section 16.02, of any such increase in the Conversion Rate. Subject to
      applicable stock exchange rules and listing standards, the Company shall be
      entitled to increase the Conversion Rate, in addition to the events requiring
      an
      increase in the Conversion Rate pursuant to Section 7.05, as it in its
      discretion shall determine to be advisable in order to avoid or diminish any
      tax
      to stockholders in connection with any stock dividends, subdivisions of shares,
      distributions of rights to purchase stock or securities or distributions of
      securities convertible into or exchangeable for stock hereafter made by the
      Company to its stockholders.

     

    Section
      7.10   Notice
      of Adjustment.

     

    Whenever
      the Conversion Rate or conversion privilege is adjusted, the Company shall
      promptly mail to Securityholders a notice of the adjustment in accordance with
      Section 16.02, and file with the Trustee an Officers’ Certificate briefly
      stating the Conversion Rate, the facts requiring the adjustment and the manner
      of computing it. Unless and until the Trustee shall receive an Officers’
Certificate setting forth an adjustment of the Conversion Rate, the Trustee
      may
      assume without inquiry that the Conversion Rate has not been adjusted and that
      the last Conversion Rate of which it has knowledge remains in
      effect.

     

    Section
      7.11   [Reserved].

     

    Section
      7.12   Trustee’s
      Disclaimer.

     

      The
      Trustee shall have no duty to determine when an adjustment under this Article
      7
      should be made, how it should be made or what such adjustment should be, but
      may
      accept as conclusive evidence of that fact or the correctness of any such
      adjustment set forth in, and shall be protected in relying upon, an Officers’
Certificate, including the Officers’ Certificate with respect thereto which the
      Company is obligated to file with the Trustee pursuant to Section 7.10. The
      Trustee makes no representation as to the validity or value of any securities
      or
      assets issued upon conversion of Securities, and the Trustee shall not be
      responsible for the Company’s failure to comply with any provisions of this
      Article 7.

     

    The
      Trustee shall not be under any responsibility to determine the correctness
      of
      any provisions contained in any supplemental indenture executed pursuant to
      Section 7.08, but may accept as conclusive evidence of the correctness thereof,
      and shall be fully protected in relying upon, the Officers’ Certificate and
      Opinion of Counsel with respect thereto which the Company is obligated to file
      with the Trustee pursuant to Section 7.08.

    Section
      7.13   Settlement
      Upon Conversion.

     

     (a)
      Upon any
      conversion of any Security, the Company shall deliver to converting Holders,
      in
      respect of each $1,000 Principal Amount of Securities being converted, a
“Settlement
      Amount”
equal
      to the sum of the Daily Settlement Amounts for each of the 20 Trading Days
      during the Conversion Reference Period for such Security.

     

    (b)  The
      “Daily
      Settlement Amount”
for
      each of the 20 Trading Days during the Conversion Reference Period shall consist
      of:

     

    (i)  Cash
      equal to the lesser of $50 and the Daily Conversion Value; and

     

    (ii)  to
      the
      extent the Daily Conversion Value exceeds $50, a number of shares of Common
      Stock (the “Daily
      Share Amount”)
      equal
      to (x) the difference between the Daily Conversion Value and $50, divided by
      (y)
      the Daily VWAP for such day.

     

    (c)  Upon
      conversion, Holders shall not receive any separate cash payment for accrued
      and
      unpaid interest (including Contingent Interest or Additional Interest, if any),
      unless such conversion occurs between a Record Date and the Interest Payment
      Date to which it relates and such Holder was the holder of record at the Close
      of Business on such Record Date.

     

    (d)  If
      Securities are converted after 5:00 p.m., New York City time, on a Record Date
      for the payment of interest, Holders of such Securities at 5:00 p.m., New York
      City time, on such Record Date will receive the interest payable on such
      Securities on the corresponding Interest Payment Date notwithstanding the
      conversion. Securities surrendered for conversion during the period from 5:00
      p.m., New York City time, on any Record Date to 9:00 a.m., New York City time,
      on the immediately following Interest Payment Date, must be accompanied by
      funds
      equal to the amount of interest payable on the Securities so converted;
provided
      that no
      such payment need be made (i) if the Company has specified a Repurchase Date
      following a Fundamental Change or Redemption Date in respect of the Securities
      that is after a Record Date and on or prior to the Business Day next succeeding
      the next Interest Payment Date; (ii) in respect of any conversion which occurs
      after the Record Date for the interest payment due on May 1, 2027 or (iii)
      to
      the extent of any overdue interest, if any such amount exists at the time of
      conversion with respect to such Security.

     

    (e)  On
      any
      day prior to the first Trading Day of the applicable Conversion Reference
      Period, the Company may specify by notice to the Trustee and Holders, a
      percentage of the Daily Share Amount that will be settled in cash (the
“Cash
      Percentage”).
      If
      the Company elects to specify a Cash Percentage then, in lieu of all or a
      portion of the Daily Share Amount for each Trading Day in the applicable
      Conversion Reference Period, the Company shall deliver Cash equal to the product
      of (i) the Cash Percentage, (ii) the Daily Share Amount for such Trading Day
      and
      (iii) the Daily VWAP for such Trading Day. The number of shares of Common Stock
      in respect of the Daily Share Amount for each Trading Day in the applicable
      Conversion Reference Period shall equal the product of (x) the Daily Share
      Amount and (y) 100% minus the Cash Percentage. If the Company does not specify
      a
      Cash Percentage by the start of the applicable Conversion Reference Period,
      the
      Company shall settle 100% of the Daily Share Amount for each Trading Day in
      the
      applicable Conversion Reference Period with shares of Common Stock; provided,
      however,
      that
      (i) the Company shall pay cash in lieu of fractional shares otherwise issuable
      upon conversion of such Security
      and
      (ii) if conversion of the Securities is in connection with a transaction
      described in ‎Section 7.08 pursuant to which the Securities become convertible
      into cash and Reference Property, the Company shall settle such conversion
      in
      Cash and Reference Property.

     

    
      
        
        

      

      
        47

        
          

        

      

      
        
        

      

    

    (f)  The
      Company shall determine the Daily Conversion Value and the number of shares
      of
      Common Stock, if any, to be issued upon conversion of the Securities at the
      end
      of the Conversion Reference Period.

     

    (g)  Upon
      conversion of any Securities, the Company will pay the Cash and deliver the
      shares of Common Stock, as applicable, as promptly as practicable after
      expiration of the Conversion Reference Period, but in no event later than the
      third Business Day after such expiration.

     

    (h)  The
      Company shall not issue fractional shares of Common Stock upon conversion of
      Securities. If multiple Securities shall be surrendered for conversion at one
      time by the same Holder, the number of full shares which shall be issuable
      upon
      conversion shall be computed on the basis of the aggregate Principal Amount
      of
      the Securities (or specified portions thereof to the extent permitted hereby)
      so
      surrendered. If any fractional share of stock would be issuable upon the
      conversion of any Securities, the Company shall make payment therefor in cash
      equal to the fraction of a share of Common Stock otherwise issuable multiplied
      by the Daily VWAP for the final Trading Day of the applicable Conversion
      Reference Period.

     

    (i)  Except
      as
      otherwise provided in this Indenture, no payment or adjustments in respect
      of
      payments of interest (including Contingent Interest or Additional Interest,
      if
      any) on Securities surrendered for conversion or any dividends or distributions
      on the Common Stock issued upon conversion shall be made upon the conversion
      of
      any Securities.

     

    (j)  For
      the
      purposes of Section 7.13, in the event that any of Daily Settlement Amount,
      Daily Conversion Value, Daily Share Amount or Daily VWAP is not calculable
      for
      all portions of the Conversion Reference Period, the Company’s Board of
      Directors shall in good faith determine the values necessary to calculate the
      Daily Settlement Amount, Daily Conversion Value, Daily Share Amount and Daily
      VWAP, as applicable.

    Contingent
      Interest

     

    Section
      8.01   Contingent
      Interest.

     

     (a)
      Beginning with the six-month period commencing on November 1, 2010 and ending
      on
      April 30, 2011, and for each six-month period from May 1 to October 31
      and from November 1 to April 30 thereafter, the Company shall pay
      Contingent Interest with respect to the Securities for any Contingent Interest
      Period if the average Trading Price per $1,000 principal amount of Securities
      during the five consecutive Trading Days ending three Trading Days before the
      applicable Contingent Interest Period equals or exceeds 120% of the principal
      amount of such Securities.

     

    (b)  The
      amount of Contingent Interest payable per $1,000 principal amount of Securities
      in respect of any Contingent Interest Period shall equal 0.25% per annum of
      the

      Company of a Notice of Default, provided,
      however,
      that
      the Company shall have 120 days after receipt of a Notice of Default to remedy,

      principal or accrued interest with respect to Indebtedness, where the amount

      other
      act on the part of the Trustee or any Holder.

    The
      Holders of a majority in aggregate principal amount of the Securities then
      outstanding by notice to the Trustee may rescind an acceleration of Securities
      and its consequences before a judgment or decree for the payment of money has
      been obtained by the Trustee if (a) the rescission would not conflict with
      any
      existing order or decree, (b) all existing Events of Default, other than the
      nonpayment of the principal of, plus accrued and unpaid interest (including
      Contingent Interest or Additional Interest, if any) on, the Securities that
      has
      become due solely by such declaration of acceleration, have been cured or waived
      and (c) all payments due to the Trustee and any predecessor Trustee under
      Section 12.06 have been made. No such rescission shall affect any subsequent
      Default or impair any right consequent thereto.

     

    Section
      11.03   Other
      Remedies.

     

    If
      an
      Event of Default occurs and is continuing, the Trustee may, but shall not be
      obligated to, pursue any available remedy by proceeding at law or in equity
      to
      collect the payment of the principal of or accrued and unpaid interest
      (including Contingent Interest and Additional Interest, if any) on the
      Securities, the payment of Cash and, if applicable, shares of Common Stock
      upon
      conversion or to enforce the performance of any provision of the Securities
      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. A delay or
      omission by the Trustee or any Securityholder in exercising any right or remedy
      accruing upon an Event of Default shall not impair the right or remedy or
      constitute a waiver of or acquiescence in the Event of Default. No remedy is
      exclusive of any other remedy. All available remedies are cumulative to the
      extent permitted by law.

     

    Section
      11.04   Waiver
      of Defaults and Events of Default.

     

    Subject
      to Section 11.07 and 13.02, the Holders of a majority in aggregate principal
      amount of the Securities then outstanding by notice to the Trustee may waive
      an
      existing or future Default or Event of Default and its consequences, except
      a
      Default or Event of Default in the payment of the principal of, or any interest
      (including Contingent Interest and Additional Interest, if any) on any Security
      when due at maturity or upon redemption, or the payment of any applicable
      Repurchase Price or Fundamental Change Purchase Price, or a failure by the
      Company to deliver Cash and, if applicable, shares of Common Stock upon
      conversion in accordance with Article 7 or any Default or Event of Default
      in
      respect of any provision of this Indenture or the Securities that, under Section
      13.02, cannot be modified or amended without the consent of the Holders of
      each
      outstanding Security. When a Default or Event of Default is waived, it is deemed
      cured, but no such waiver shall extend to any subsequent or other Default or
      impair any consequent right. This Section 11.04 shall be in lieu of Section
      316(a)(1)(B) of the TIA and such Section 316(a)(1)(B) is hereby expressly
      excluded from this Indenture, as permitted by the TIA.

     

    Section
      11.05   Control
      by Majority.

     

    The
      Holders of a majority in aggregate principal amount of the Securities then
      outstanding 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 it under this Indenture. However, the Trustee may refuse to follow
      any direction that conflicts with law or this Indenture, that the Trustee
      determines may be unduly prejudicial to the rights of another Holder or the
      Trustee, or that may involve the Trustee in personal liability unless the
      Trustee is offered security or indemnity reasonably satisfactory to it;
provided
      that the
      Trustee may take any other action deemed proper by the Trustee which is not
      inconsistent with such direction. This Section 11.05 shall be in lieu of Section
      316(a)(1)(A) of the TIA and such Section 316(a)(1)(A) is hereby expressly
      excluded from this Indenture, as permitted by the TIA.

     

    Section
      11.06   Limitations
      on Suits.

     

    Subject
      to Section 11.07, a Holder of a Security may not pursue any remedy with respect
      to this Indenture or the Securities unless:

     

    (a)  the
      Holder gives to the Trustee written notice of a continuing Event of
      Default;

     

    
      
        
        

      

      
        54

        
          

        

      

      
        
        

      

    

    (b)  the
      Holders of at least 25% in aggregate principal amount of the then outstanding
      Securities make a written request to the Trustee to pursue the
      remedy;

     

    (c)  such
      Holder or Holders offer to the Trustee security or indemnity reasonably
      satisfactory to the Trustee against any loss, liability or expense;

     

    (d)  the
      Trustee does not comply with the request within 60 days after receipt of the
      notice, request and the offer of security or indemnity; and

     

    (e)  no
      direction inconsistent with such written request has been given to the Trustee
      during such 60-day period by the Holders of a majority in aggregate principal
      amount of the Securities then outstanding.

     

    Section
      11.07   Rights
      of Holders to Receive Payment and to Convert.

     

    .
      Notwithstanding any other provision of this Indenture, the right of any Holder
      of a Security to receive payment in Cash of the principal amount, Repurchase
      Price, Fundamental Change Purchase Price or interest (including Contingent
      Interest and Additional Interest, if any) on any Security, on or after the
      respective due dates or Redemption Dates expressed in the Security and this
      Indenture, receive payment in Cash and, if applicable, shares of Common Stock
      or
      other property upon conversion in accordance with Article 7 or upon redemption
      in accordance with Article 5 and to bring suit for the enforcement of any such
      payment on or after such respective dates or the right to convert, is absolute
      and unconditional and shall not be impaired or affected without the consent
      of
      the Holder.

     

    Section
      11.08   Collection
      Suit by Trustee.

     

    If
      an
      Event of Default in the payment of principal or interest, Contingent Interest
      or
      Additional Interest specified in clause (a) or (b) of Section 11.01 occurs
      and
      is continuing, the Trustee may recover judgment in its own name and as trustee
      of an express trust against the Company or another obligor on the Securities
      for
      the whole amount owing with respect to the Securities and the amounts provided
      for in Section 12.06.

     

    Section
      11.09   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 the reasonable compensation, expenses, disbursements and advances
      of
      the Trustee, its agents and counsel) 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 money or other property payable or deliverable on any such claims
      and to distribute the same, and any Custodian 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 for the reasonable
      compensation, expenses, disbursements and advances of the Trustee, its agents
      and counsel, and any other amounts due the Trustee under Section 12.06, and
      to
      the extent that such payment of the reasonable compensation, expenses,
      disbursements and advances in any such proceedings shall be denied for any
      reason, payment of the same shall be secured by a lien on, and shall be paid
      out
      of, any and all distributions, dividends, money, securities and other property
      which the Holders may be entitled to receive in such proceedings, whether in
      liquidation or under any plan of reorganization or arrangement or otherwise.
      Nothing herein contained shall be deemed to authorize the Trustee to authorize
      or consent to or, on behalf of any Holder, to authorize, accept or adopt 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
      11.10   Priorities.

     

    Any
      money
      or property collected by the Trustee pursuant to this Article 11, and after
      an
      Event of Default, any money or other property distributable in respect of the
      Company’s obligations under this Indenture shall be paid out in the following
      order:

     

    First,
      to
      the Trustee (including any predecessor Trustee) for amounts due under Section
      12.06;

     

    Second,
      to Securityholders for amounts due and unpaid on the Securities for the
      principal amount, interest (including Contingent Interest and Additional
      Interest, if any), the Fundamental Change Purchase Price, the Repurchase Price,
      the Redemption Price, amounts due upon conversion (including amounts resulting
      from a Makewhole Fundamental Change), as the case may be, ratably, without
      preference or priority of any kind, according to such amounts due and payable
      on
      the Securities; and

     

    Third,
      the balance, if any, to the Company.

     

    The
      Trustee may fix a record date and payment date for any payment to Holders
      pursuant to this Section 11.10. At least 15 days before such record date, the
      Trustee shall mail to each Holder and the Company a notice that states the
      record date, the payment date and the amount to be paid.

     

    Section
      11.11   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,
      a
      court in its discretion may require the filing by any party litigant in the
      suit
      of an undertaking to pay the costs of the suit, and the court in its discretion
      may assess reasonable costs, including reasonable attorneys’ fees and expenses,
      against any party litigant in the suit, having due regard to the merits and
      good
      faith of the claims or defenses made by the party litigant. This Section 11.11
      does not apply to a suit made by the Trustee, a suit by a Holder pursuant to
      Section 11.07, or a suit by Holders of more than 10% in aggregate principal
      amount of the Securities then outstanding.

     

    Section
      11.12   Delay
      or Omission Not Waiver.

     

    No
      delay
      or omission of the Trustee or of any Holder of any Security 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 11 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
      12  

     

    Trustee

     

    Section
      12.01   Certain
      Duties and Responsibilities of Trustee.

     

     (a)  In
      case an Event of Default with respect to the Securities has occurred (that
      has
      not been cured or waived), the Trustee shall exercise with respect to the
      Securities such of the rights and powers vested in it by this Indenture, and
      use
      the same degree of care and skill in their exercise, as a prudent person would
      exercise or use under the circumstances in the conduct of his or her own
      affairs.

     

    (b)  Prior
      to
      the occurrence of an Event of Default with respect to the Securities and after
      the curing or waiving of all such Events of Default with respect to the
      Securities that may have occurred:

     

    (i)  the
      duties and obligations of the Trustee shall with respect to the Securities
      be
      determined solely by the express provisions of this Indenture, and the Trustee
      shall not be liable with respect to the Securities except for the performance
      of
      such duties and obligations as are specifically set forth in this Indenture,
      and
      no implied covenants or obligations shall be read into this Indenture against
      the Trustee; and

     

    
      
        
        

      

      
        56

        
          

        

      

      
        
        

      

    

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

     

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

     

    (i)  this
      subsection shall not be construed to limit the effect of Section
      12.01(b);

     

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

     

    (iii)  the
      Trustee shall not be liable with respect to any action taken or omitted to
      be
      taken by it in good faith in accordance with the direction of the Holders of
      not
      less than a majority in principal amount of the Securities at the time
      outstanding (determined as provided in Section 2.08) relating to the time,
      method and place of conducting any proceeding for any remedy available to the
      Trustee, or exercising any trust or power conferred upon the Trustee under
      this
      Indenture with respect to the Securities; and

     

    (iv)  none
      of
      the provisions contained in this Indenture shall require the Trustee to expend
      or risk its own funds or otherwise incur personal financial liability in the
      performance of any of its duties or in the exercise of any of its rights or
      powers, if there is reasonable ground for believing that the repayment of such
      funds or liability is not reasonably assured to it under the terms of this
      Indenture or adequate indemnity against such risk is not reasonably assured
      to
      it.

     

    (d)  Whether
      or not expressly so provided, every provision of this Indenture relating to
      the
      conduct or affecting the liability or affording protection to the Trustee (in
      any capacity, including Paying Agent, Registrar or Conversion Agent) shall
      be
      subject to the provisions of this Section.

     

    Section
      12.02   Certain
      Rights of Trustee.

     

    Except
      as
      otherwise provided in Section 12.01:

     

    (a)  The
      Trustee may conclusively rely and shall be fully protected in acting or
      refraining from acting upon any resolution, certificate, statement, instrument,
      opinion, report, notice, request, consent, order, approval, bond, security
      or
      other paper or document (whether in original or facsimile form) believed by
      it
      in good faith to be genuine and to have been signed or presented by the proper
      party or parties. The Trustee need not investigate any fact or matter stated
      in
      any such document;

     

    (b)  Any
      request, direction, order or demand of the Company mentioned herein shall be
      sufficiently evidenced by a resolution of the Company’s Board of Directors or an
      instrument signed in the name of the Company, by one or more Officers thereof
      (unless other evidence in respect thereof is specifically prescribed
      herein);

     

    (c)  Before
      the Trustee acts or refrains from acting, it may require an Officers’
Certificate or an Opinion of Counsel or both. The Trustee shall not be liable
      for any action it takes or omits to take in good faith in reliance on such
      Officers’ Certificate or Opinion of Counsel. The Trustee may consult with
      counsel of its own selection and the advice of such counsel and Opinions of
      Counsel with respect to legal matters relating to this Indenture and the
      Securities shall be full and complete authorization and protection from
      liability in respect of any action taken, suffered or omitted by it hereunder
      in
      good faith and in reliance thereon;

     

    
      
        
        

      

      
        57

        
          

        

      

      
        
        

      

    

    (d)  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
      Securityholders, pursuant to the provisions of this Indenture, unless such
      Securityholders shall have offered to the Trustee security or indemnity
      reasonably satisfactory to it against the costs, expenses and liabilities that
      may be incurred therein or thereby;

     

    (e)  The
      Trustee shall not be liable for any action taken or omitted to be taken by
      it in
      good faith and believed by it to be authorized or within the discretion or
      rights or powers conferred upon it by this Indenture;

     

    (f)  The
      Trustee shall not be bound to make any investigation into the facts or matters
      stated in any resolution, certificate, statement, instrument, opinion, report,
      notice, request, consent, order, approval, bond, security, or other papers
      or
      documents, but the Trustee, in its discretion, may make even further inquiry
      or
      investigation into such facts or matters as it may see fit; and, if the Trustee
      shall determine to make such further inquiry or investigation, it shall be
      entitled to examine the books, records and premises of the Company, personally
      or by agent or attorney at the sole cost of the Company and shall incur no
      liability or additional liability of any kind by reason of such inquiry or
      investigation;

     

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

     

    (h)  The
      Trustee shall not be deemed to have knowledge or be charged with knowledge
      of an
      Event of Default except (i) if the Trustee is acting as Paying Agent, any
      Default or Event of Default occurring pursuant to Sections 9.01, 11.01(a) or
      11.01(b) and (ii) any Default or Event of Default of which the Trustee shall
      have received written notification which references the Securities and this
      Indenture or of which a Trust Officer shall have obtained actual knowledge.
      Delivery of reports, information and documents to the Trustee under Section
      9.02
      is for informational purposes only and the Trustee’s receipt of the foregoing
      shall not constitute constructive notice of any information contained therein
      or
      determinable from information contained therein, including the Company’s
      compliance with any of its covenants hereunder (as to which the Trustee is
      entitled to rely exclusively on Officers’ Certificates, except as otherwise
      provided herein);

     

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

     

    (j)  The
      permissive right of the Trustee to take or refrain from taking any actions
      enumerated in this Indenture shall not be construed as a duty;

     

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

     

    
      
        
        

      

      
        58

        
          

        

      

      
        
        

      

    

    (l)  Anything
      in this Indenture notwithstanding, in no event shall the Trustee be liable
      for
      special, indirect, punitive or consequential loss or damage of any kind
      whatsoever (including but not limited to loss of profit), even if the Trustee
      has been advised as to the likelihood of such loss or damage and regardless
      of
      the form of action; and

     

    (m)  The
      Trustee shall not be responsible or liable for any failure or delay in the
      performance of its obligations under this Indenture arising out of or caused,

     (a)
      The

      of
      the same.

     

    (b)  The
      Trustee makes no representations as to the validity or sufficiency of this

      in accordance with any provision of this Indenture or established pursuant

      Held in Trust.

     

    Subject
      to the provisions of Section 15.02, all moneys received by the Trustee shall,

      for

      to
      the extent required by law. The Trustee shall be under no liability for interest
      on any moneys received by it hereunder except such as it may agree in writing
      with the Company to pay thereon.

     

    Section
      12.06   Compensation
      and Reimbursement.

     

     (a)
      The
      Company covenants and agrees to pay to the Trustee, and the Trustee shall be
      entitled to, such compensation (which shall not be limited by any provision
      of
      law in regard to the compensation of a trustee of an express trust), as the
      Company and the Trustee may from time to time agree in writing for all services
      rendered by it in the execution of the trusts hereby created and in the exercise
      and performance of any of the powers and duties hereunder of the Trustee, and,

      any of the provisions of this Indenture (including the reasonable compensation
      and the expenses and disbursements of its counsel and of all Persons not
      regularly in its employ) except any such expense, disbursement or advance as
      may
      arise from the Trustee’s gross negligence, bad faith or willful misconduct. The
      Company covenants and agrees to indemnify the Trustee (and its officers, agents,
      directors, stockholders and employees) for, and to hold it harmless against,
      any
      loss, liability or expense (including, without limitation, reasonable attorney’s
      fees and expenses) incurred without gross negligence or bad faith or willful
      misconduct on the part of the Trustee and arising out of or in connection with
      the acceptance or administration of this trust, including the reasonable costs
      and expenses of defending itself against any claim of liability in the
      premises.

    (b)  The
      obligations of the Company under this Section to compensate and indemnify the
      Trustee and to pay or reimburse the Trustee for reasonable expenses,
      disbursements and advances shall constitute additional indebtedness hereunder.
      Such additional indebtedness shall be secured by a lien prior 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.

     

    (c)  When
      the
      Trustee incurs expenses or renders services after an Event of Default specified
      in Section 11.01(h) or (i) occurs, the expenses and the compensation for the
      services are intended to constitute expenses of administration under any
      Bankruptcy Law.

     

    (d)  For
      the
      purposes of this Section 12.06, the “Trustee” shall include any predecessor
      Trustee; provided,
      however,
      that
      the gross negligence, bad faith or willful misconduct of any Trustee or other
      indemnified party hereunder shall not affect the rights of any other Trustee
      hereunder.

     

    (e)  The
      provisions of this Section shall survive the discharge of this Indenture and
      resignation or removal of the Trustee.

      12.07   Reliance
      on Officers’ Certificate.

     

    Except
      as
      otherwise provided in Section 12.01, whenever in the administration of the
      provisions 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
      to take any action hereunder, such matter (unless other evidence in respect
      thereof be herein specifically prescribed) may, in the absence of bad faith
      on
      the part of the Trustee, be deemed to be conclusively proved and established
      by
      an Officers’ Certificate or Opinion of Counsel delivered to the Trustee and such
      certificate, in the absence of bad faith on the part of the Trustee, shall
      be
      full warrant to the Trustee for any action taken, suffered or omitted to be
      taken by it under the provisions of this Indenture upon the faith
      thereof.

     

    Section
      12.08   Disqualification:

    There
      shall at all times be a Trustee with respect to the Securities issued hereunder
      which shall at all times be a corporation organized and doing business under
      the
      laws of the United States of America or any State or Territory thereof or of
      the
      District of Columbia, or a corporation or other Person permitted to act as

      powers, having a combined capital and surplus, or being a member of a bank
      holding company with a combined capital and surplus, of at least 50 million
      U.S.
      dollars ($50,000,000), and subject to supervision or examination by Federal,
      State, Territorial or District of Columbia authority. If such corporation
      publishes reports of condition at least annually, pursuant to law or to the
      requirements of the aforesaid supervising or examining authority, then for
      the
      purposes of this Section, the combined capital and surplus of such corporation
      shall be deemed to be its combined capital and surplus as set forth in its
      most
      recent report of condition so published. The Company may not, nor may any Person
      directly or indirectly controlling, controlled by, or under common control
      with
      the Company, serve as Trustee. In case at any time the Trustee shall cease
      to be
      eligible in accordance with the provisions of this Section, the Trustee shall
      resign immediately in the manner and with the effect specified in Section
      12.10.

    Section
      12.10   Resignation
      and Removal; Appointment of Successor..
      (a)
      The
      Trustee or any successor hereafter appointed may at any time resign as Trustee
      with respect to the Securities by giving written notice thereof to the Company
      and by transmitting notice of resignation by mail, first class postage prepaid,
      to the Securityholders, as their names and addresses appear upon the Register.
      Upon receiving such notice of resignation, the Company shall promptly appoint
      a
      successor trustee with respect to the Securities by or pursuant to a resolution
      of the Board of Directors. If no successor trustee shall have been so appointed
      and have accepted appointment within 30 days after the mailing of such notice
      of
      resignation, the resigning Trustee may petition any court of competent
      jurisdiction for the appointment of a successor trustee with respect to the
      Securities, or any Securityholder who has been a bona fide holder of a Security
      or Securities for at least six months may on behalf of himself and all others
      similarly situated, petition any such court for the appointment of a successor
      trustee, in either case at the sole cost and expense of the Company. Such court
      may thereupon after such notice, if any, as it may deem proper and prescribe,
      appoint a successor trustee.

     

    (b)  In
      case
      at any time any one of the following shall occur:

     

    (i)  the
      Trustee shall fail to comply with the provisions of Section 12.08 after written
      request therefor by the Company or by any Securityholder who has been a bona
      fide holder of a Security or Securities for at least six months;

     

    (ii)  the
      Trustee shall cease to be eligible in accordance with the provisions of Section
      12.09 and shall fail to resign after written request therefor by the Company
      or
      by any such Securityholder; or

     

    (iii)  the
      Trustee shall become incapable of acting, or shall be adjudged a bankrupt or
      insolvent, or commence a voluntary bankruptcy proceeding, or a receiver of
      the
      Trustee or of its property shall be appointed or consented to, or any public
      officer shall take charge or control of the Trustee or of its property or
      affairs for the purpose of rehabilitation, conservation or
      liquidation;

     

    then,
      in
      any such case, the Company may remove the Trustee with respect to all Securities
      and appoint a successor trustee by or pursuant to a resolution of the Board
      of
      Directors, or, unless the Trustee’s duty to resign is stayed as provided herein,
      subject to Section 11.11, any Securityholder who has been a bona fide holder
      of
      a Security or Securities for at least six months may, on behalf of that Holder
      and all others similarly situated, petition any court of competent jurisdiction
      for the removal of the Trustee and the appointment of a successor trustee.
      Such
      court may thereupon after such notice, if any, as it may deem proper and
      prescribe, remove the Trustee and appoint a successor trustee.

     

    (c)  The
      Holders of a majority in aggregate principal amount of the Securities at the
      time outstanding may at any time remove the Trustee by so notifying the Trustee
      and the Company and may appoint a successor Trustee with the consent of the
      Company. If no successor trustee shall have been so appointed and have accepted
      appointment within 30 days after such notification of removal by the Holders,
      the Trustee to be removed may petition any court of competent jurisdiction
      for
      the appointment of a successor trustee with respect to the Securities, or any
      Securityholder who has been a bona fide holder of a Security or Securities
      for
      at least six months may on behalf of himself and all others similarly situated,
      petition any such court for the appointment of a successor trustee, in either
      case at the sole cost and expense of the Company. Such court may, as it may
      deem
      proper prescribe or appoint a successor trustee.

     

    (d)  Notwithstanding
      anything herein to the contrary, any resignation or removal of the Trustee
      and
      appointment of a successor trustee with respect to the Securities pursuant
      to
      any of the provisions of this Section shall become effective upon acceptance
      of
      appointment by the successor trustee as provided in Section 12.11.

     

    
      
        
        

      

      
        61

        
          

        

      

      
        
        

      

    

    (e)  So
      long
      as no event which is, or, after notice or lapse of time, or both, would become,
      an Event of Default shall have occurred and be continuing, and except with
      respect to a Trustee appointed by the Holders of a majority in principal amount
      of the Securities at that time outstanding pursuant to subsection (c) of this
      Section, if the Company shall have delivered to the Trustee (i) a resolution
      of
      the Board of Directors appointing a successor Trustee, effective as of a date
      specified therein, and (ii) an instrument of acceptance of such appointment,
      effective as of such date, by such successor Trustee in accordance with Section
      12.11, the Trustee shall be deemed to have resigned as contemplated in
      subsection (a) of this Section, the successor Trustee shall be deemed to have
      been appointed by the Company pursuant to subsection (a) of this Section and
      such appointment shall be deemed to have been accepted as contemplated in
      Section 12.11, all as of such date, and all other provisions of this Section
      and
      Section 12.11 shall be applicable to such resignation, appointment and
      acceptance except to the extent inconsistent with this subsection
      (e).

     

    (f)  At
      any
      time there shall be only one Trustee with respect to the
      Securities.

     

    Section
      12.11   Acceptance
      of Appointment By Successor.

     

     (a)
      In case
      of the appointment hereunder of a successor trustee with respect to the
      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
      all other amounts payable to it hereunder, execute and deliver an instrument
      transferring to such successor trustee all the rights, powers, and trusts of
      the
      retiring Trustee and shall duly assign, transfer and deliver to such successor
      trustee all property and money held by such retiring Trustee hereunder, subject
      to the lien provided for in Section 12.06(b).

     

    (b)  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 subsection
      (a) of this Section.

     

    (c)  No
      successor trustee shall accept its appointment unless at the time of such
      acceptance such successor trustee shall be qualified and eligible under this
      Article 12.

     

    (d)  Upon
      acceptance of appointment by a successor trustee as provided in this Section,
      the Company shall transmit notice of the succession of such trustee hereunder
      by
      mail, first class postage prepaid, to the Securityholders, as their names and
      addresses appear upon the Register. If the Company fails to transmit such notice
      within ten days after acceptance of appointment by the successor trustee, the
      successor trustee shall cause such notice to be transmitted at the expense
      of
      the Company.

     

    Section
      12.12   Merger,
      Conversion, Consolidation or Succession to Business.

     

    Any
      corporation or other business entity into which the Trustee may be merged or
      converted or with which it may be consolidated, or any corporation or other
      business entity resulting from any merger, conversion or consolidation to which
      the Trustee shall be a party, or any corporation or other business entity
      succeeding to all or substantially all of the corporate trust business of the
      Trustee, including the administration of this Indenture, shall be the successor
      of the Trustee hereunder, provided that such corporation or other business
      entity shall be qualified under the provisions of Section 12.08 and eligible
      under the provisions of Section 12.09, without the execution or filing of any
      paper or any further act on the part of any of the parties hereto, anything
      herein to the contrary notwithstanding. In case any Securities shall have been
      authenticated, but not delivered, by the Trustee then in office, any successor
      by merger, conversion or consolidation to such authenticating Trustee may adopt
      such authentication and deliver the Securities so authenticated with the same
      effect as if such successor Trustee had itself authenticated such
      Securities.

    The
      Trustee shall comply with Section 311(a) of the TIA, excluding any creditor

      or been removed shall be subject to Section 311(a) of the TIA to the extent
      included therein.

     

    Section
      12.14   Notice
      of Defaults.

     

    If
      a
      Default or Event of Default occurs and is continuing hereunder and if it is
      actually known to a Trust Officer of the Trustee, the Trustee shall mail to
      each
      Holder notice of the Default or Event of Default within 90 days after such
      Default or Event of Default. Except in the case of a default in payment of
      principal of or interest (including Contingent Interest or Additional Interest,
      if any) on any Security, the Trustee may withhold the notice if and so long
      as a
      committee of its Trust Officers in good faith determines that withholding the
      notice is in the interest of the Holders of such Securities.

     

    Section
      12.15   Reports
      by Trustee.

     

     (a)
      Within

      pursuant thereto. In the event that, on any such reporting date, no events
      have
      occurred under the applicable sections of the TIA within the 12 months preceding
      such reporting date, the Trustee shall be under no duty or obligation to provide
      such reports. The Trustee shall also comply with TIA Section 313(b)(2). The
      Trustee shall transmit by mail all reports as required by TIA Section
      313(c).

     

    (b)  A
      copy of
      each such report shall, at the time of such transmission to Securityholders,
      be
      delivered to the Company and filed by the Trustee with each stock exchange
      upon
      which the Securities are listed and with the SEC in accordance with TIA Section
      313(d). The Company shall notify the Trustee when the Securities are listed
      on
      any stock exchange and of any delisting thereof.

      of
      the TIA regarding the collection of claims against the Company (or any such
      other obligor).

    Section
      13.02   With
      Consent of Holders.

     

    The
      Company and the Trustee may amend or supplement the Securities or this Indenture
      with the consent of the Holders of at least a majority in aggregate principal
      amount of the Securities then outstanding. Subject to Section 11.04 and Section
      11.07, the Holders of at least a majority in aggregate principal amount of
      the
      Securities then outstanding may waive compliance in any instance by the Company
      with any provision of the Securities or this Indenture or waive any past default
      under this Indenture and its consequences, except a default in the payment
      of
      any amount due, or in the obligation to deliver Common Stock, with respect
      to
      any Security or in respect of any provision which under this Indenture cannot
      be
      modified or amended, in each case without notice to any Securityholder. However,
      notwithstanding the foregoing but subject to Section 13.04, without the consent
      of the Holders of each Security then outstanding, an amendment, supplement
      or
      waiver may not:

     

    
      
        
        

      

      
        64

        
          

        

      

      
        
        

      

    

    (a)  change
      the stated maturity of the principal of or the payment date of any installment
      of interest (including Contingent Interest or Additional Interest, if any)

    (b)  reduce
      the principal amount, the Redemption Price, Repurchase Price or Fundamental
      Change Purchase Price, or the Conversion Rate (except as provided in this
      Indenture) of any Security or rate of interest, Contingent Interest or
      Additional Interest on, any Security;

     

    (c)  reduce
      the amount of principal payable upon acceleration of the maturity of any
      Security;

     

    (d)  change
      the currency in which payment of principal, the Redemption Price, Repurchase
      Price or Fundamental Change Purchase Price, or interest (including Contingent
      Interest or Additional Interest, if any) with respect to, the Securities is
      payable;

     

    (e)  impair
      the right to institute suit for the enforcement of any payment on, or with
      respect to, any Security;

     

    (f)  modify
      the provisions with respect to the repurchase rights of Holders as provided
      in
      Article 5 in a manner adverse to Holders;

     

    (g)  adversely
      affect the right of Holders to convert Securities other than as provided in
      this
      Indenture;

     

    (h)  reduce
      the percentage in principal amount of the outstanding Securities, the consent
      of
      whose Holders is required to take specific actions including, but not limited
      to, the waiver of past defaults or the modification or amendment of this
      Indenture; or

     

    (i)  alter
      the
      manner of calculation or rate of accrual of interest (including Contingent
      Interest or Additional Interest, if any), the Redemption Price, Repurchase
      Price, Fundamental Change Purchase Price or the Conversion Rate (except as
      permitted under this Indenture) on any Security or extend the time for payment
      of any such amount or shorten the time for redemption.

     

    It
      shall
      not be necessary for the consent of the Holders under this Section 13.02 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 Section 13.01 or this Section 13.02
      becomes effective, the Company shall mail to the Holders affected thereby a
      notice briefly describing the amendment, supplement or waiver. 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 amendment, supplement or
      waiver.

     

    Section
      13.03   Compliance
      with Trust Indenture Act.

     

    Every
      amendment to or supplement of this Indenture or the Securities shall comply
      with
      the TIA as in effect at the date of such amendment or supplement.

     

    Section
      13.04   Revocation
      and Effect of Consents.

     

    Until
      an
      amendment, supplement 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 consenting Holder’s
      Security, even if notation of the consent is not made on any Security. However,
      any such Holder or subsequent Holder may revoke the consent as to its Security
      or portion of a Security if the Trustee receives the notice of revocation before
      the date the amendment, supplement or waiver becomes effective.

    After
      an
      amendment, supplement or waiver becomes effective, it shall bind every
      applicable Securityholder.

     

    Section
      13.05   Notation
      on or Exchange of Securities.

     

    If
      an
      amendment, supplement or waiver changes the terms of a Security, the Trustee
      may
      require the Holder of the Security 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. 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 that reflects the changed terms.

     

    Section
      13.06   Trustee
      to Sign Amendments, Etc.

     

    The
      Trustee shall sign any amendment or supplemental indenture authorized pursuant
      to this Article 13 if the amendment or supplemental indenture does not adversely
      affect the rights, duties, liabilities or immunities of the Trustee in any
      material respect. If it does adversely affect the rights, duties, liabilities
      or
      immunities of the Trustee in any material respect, the Trustee may, in its
      sole
      discretion, but need not sign it. In signing or refusing to sign such amendment
      or supplemental indenture, the Trustee shall be provided with and, subject
      to
      Section 12.01, shall be fully protected in relying upon, an Officers’
Certificate and an Opinion of Counsel stating that such amendment or
      supplemental indenture is authorized or permitted by this Indenture and that
      all
      conditions precedent to the effectiveness of such amendment or supplement have
      been satisfied or duly waived.

     

    Section
      13.07   Effect
      of Supplemental Indentures.

     

    Upon
      the
      execution of any supplemental indenture under this Article, this Indenture
      shall
      be modified in accordance therewith, and such supplemental indenture shall
      form
      a part of this Indenture for all purposes; and every Holder of Securities
      theretofore or thereafter authenticated and delivered hereunder shall be bound
      thereby.

      for), and the Trustee, on demand of and at the expense of the Company, shall
      execute proper instruments acknowledging satisfaction and discharge of this

    (a)  either

     

    (i)  all
      Securities theretofore authenticated and delivered (other than Securities that
      have been destroyed, lost or stolen and which have been replaced or paid as
      provided in Section 2.07) have been delivered to the Trustee for cancellation;
      or

     

    (ii)  all

      Securities not theretofore delivered to the Trustee for cancellation have become
      due and payable whether at the Maturity Date, any Redemption Date or Repurchase
      Date, upon acceleration, upon conversion or otherwise and the Company deposits

      Stock or other consideration, or a combination thereof, as applicable hereunder,

      Counsel, each stating that all conditions precedent herein provided for relating
      to the satisfaction and discharge of this Indenture have been complied
      with.

     

    Notwithstanding
      the satisfaction and discharge of this Indenture, the obligations of the Company
      to the Trustee under Section 12.06 and, if money shall have been deposited
      with
      the Trustee pursuant to Section 15.01(a)(ii), the obligations of the Trustee

      Section 2.06, Section 2.07, Section 2.08, Section 2.15, Section 2.16, Section

      subject to applicable unclaimed property law. After return to the Company,
      Holders entitled to the Cash or securities must look to the Company for payment
      as general creditors unless an applicable abandoned property law designates
      another person and the Trustee, the Paying Agent and the Conversion Agent shall
      have no further liability to the Securityholders with respect to such Cash
      or
      securities for that period commencing after the return thereof.

      principal amount of ($ ) on May 1, 2027, and to pay interest thereon, in
      arrears, from and including the most recent Interest Payment Date to which
      interest has been paid or duly provided for (or if no interest has been paid,
      from, and including April 24, 2007), to, but excluding, May 1 and November
      1 of
      each year (each, an “Interest
      Payment Date”),
      beginning on November 1, 2007, at a rate of 3.125% per annum until the principal
      hereof is paid or made available for payment at May 1, 2027, or upon
      acceleration, or until such date on which this Security is converted, redeemed
      or purchased as provided herein. The interest so payable and punctually paid
      or
      duly provided for on any Interest Payment Date shall, as provided in the
      Indenture (as hereinafter defined), be paid to the Person in whose name this
      Security is registered at the Close of Business on the regular record date
      for
      such interest, which shall be the April 15 or October 15 (whether or not a
      Business Day), as the case may be, immediately preceding the relevant Interest
      Payment Date (each, an “Interest
      Payment Record Date”);
      provided,
      however,
      that
      interest shall be paid to a Person other than the Person in whose name this

      Date as provided herein. The Company will also pay contingent interest to the
      Holder during any six-month period from May 1 to October 31 and from November

      three trading days before the relevant six-month period equals 120% or more
      of
      the principal amount of the Security. The amount of contingent interest payable
      per $1,000 principal amount of the Security with respect to any six-month period
      will equal 0.25% per year of the average trading price of the Security for
      the

    3.125%
      CONVERTIBLE SENIOR NOTE DUE MAY 1, 2027

     

    This
      Security is one of a duly authorized issue of 3.125 % Convertible Senior Notes
      due May 1, 2027 (the “Securities”)
      of the
      Company issued under an Indenture, dated as of April 24, 2007 (the “Indenture”),
      between the Company and U.S. Bank National Association, as trustee (the
“Trustee”).
      The
      terms of this Security include those stated in the Indenture, those made part
      of
      the Indenture by reference to the Trust Indenture Act of 1939, as amended (the
      “TIA”),
      and
      those set forth in this Security. This Security is subject to all such terms,
      and Holders are referred to the Indenture and the TIA for a statement of all
      such terms. To the extent permitted by applicable law, if any provision of
      this
      Security conflicts with the express provisions of the Indenture, the provisions
      of the Indenture shall govern and be controlling. Capitalized terms used but
      not
      defined herein have the meanings assigned to them in the Indenture unless
      otherwise indicated.

              Interest.

            

    

     

    Linear
      Technology Corporation, a Delaware corporation (the “Company”),
      promises to pay interest on the principal amount of this Security at the rate
      per annum shown above. 

     

    The
      Company will pay interest, payable semi-annually in arrears, on May 1 and
      November 1 of each year, with the first payment to be made on November 1, 2007.
      Interest on this Security will accrue on the principal amount from, and
      including, the most recent date to which interest has been paid or provided
      for
      or, if no interest has been paid, from, and including, April 24, 2007, in each
      case to, but excluding, the next interest payment date or Maturity Date, as
      the
      case may be. Interest will be computed on the basis of a 360-day year of twelve
      30-day months. The Company will also pay contingent interest to the Holder
      during any six-month period from May 1 to October 31 and from November 1 to
      April 30 commencing with period beginning November 1, 2010, if the average
      Trading Price per $1,000 principal amount of the Security, during the five
      consecutive Trading Days ending three Trading Days before the relevant six-month
      period equals or exceeds 120% of the principal amount of the Security. The
      amount of contingent interest payable per $1,000 principal amount of the
      Security with respect to any six-month period will equal 0.25% per year of
      the
      average Trading Price of the Security for the five Trading Day period referred
      to above.

    Payment
      of the principal of, and interest on, this Security shall be made at the office
      of the Paying Agent in such coin or currency of the United States of America
      as
      at the time of payment is legal tender for payment of public and private debts.
      The Holder must surrender this Security to a Paying Agent to collect payment
      of
      principal. Payment of interest on Certificated Securities shall be made by
      check
      mailed to the address of the Person entitled thereto as such address appears
      in
      the Register; provided,
      however,
      that
      Holders with Securities in an aggregate principal amount in excess of $2.0
      million shall be paid, at their written election, by wire transfer of
      immediately available funds. Notwithstanding the foregoing, so long as the
      Securities are registered in the name of a Depositary or its nominee, all
      payments with respect to the Securities shall be made by wire transfer of
      immediately available funds to the account of the Depositary or its
      nominee.

      initially limited to $700,000,000 aggregate principal amount. The Company may,
      without consent of the Holders, issue additional Securities under the Indenture
      with the same terms as the Securities in an unlimited aggregate principal
      amount; provided

    This
      Security is being issued with original issue discount for U.S. federal income
      tax purposes. The issue price for this Security is $1,000 per $1,000 principal
      amount and the issue date for this Security is April 24, 2007. The comparable
      yield for this Security is 7.00% per annum, compounded semi-annually (which
      will
      be treated as the yield to maturity for U.S. federal income tax purposes).
      For
      information regarding the projected payment schedule for the Securities, holders
      should contact the general counsel of Linear Technology Corporation at 1630
      McCarthy Boulevard, Milpitas, California 95035-7417.

      to
      have agreed, with respect to each of the matters set forth below, as
      follows:

     

    (a)  Tax
      Treatment:

     

    (i) to
      treat
      the Securities as indebtedness for U.S. federal income tax purposes that is
      subject to the Treasury Regulations governing contingent payment debt
      instruments (the “contingent debt regulations”); and

     

    (ii) to
      treat
      any payment to and receipt by a Holder of cash and Common Stock upon conversion
      of a Security as a contingent payment under the contingent debt
      regulations.

     

    (b) Comparable
      Yield and Projected Payment Schedule. Solely for purposes of applying the
      contingent debt regulations:

     

    (i) for
      United States federal income tax purposes, to accrue interest with respect
      to
      outstanding Securities as original issue discount according to the
“noncontingent bond method,” as set forth in the contingent debt regulations,
      using the comparable yield of 7.00% compounded semi-annually; and

     

    (ii) the
      Company acknowledges and agrees, and each Holder and any beneficial owner of
      a
      Security, by its purchase of a Security shall be deemed to acknowledge and
      agree, that (A) the projected payment schedule is determined on the basis
      of an assumption of constant annual growth rate of the stock price, (B) the
      comparable yield and the projected payment schedule are not determined for
      any
      other purpose other than for the determination of interest accruals and
      adjustments thereof in respect of the Securities for U.S. federal income tax
      purposes and (C) the comparable yield and the projected payment schedule
      for not constitute a projection or representation regarding the actual amounts
      payable on the Securities.

      Securities in the form of beneficial interests in a Global Security that is
      a
“restricted security” within the meaning of Rule 144 under the Securities Act,
      then such transfer can be made only (x) pursuant to Rule 144A under the
      Securities Act to a transferee that the transferor reasonably believes is a
      “qualified institutional buyer,” as defined in Rule 144A, or (y) pursuant to

      Act or any similar rule that may be adopted by the Commission.

     

    (b)  If
      the
      Shelf Registration Statement is not an Automatic Shelf Registration Statement,
      the Company shall use its commercially reasonable efforts to cause the Shelf
      Registration Statement to become or be declared effective under the Act no
      later
      than 180 days after the Closing Date.

     

    (c)  The
      Company shall use its commercially reasonable efforts to keep the Shelf
      Registration Statement continuously effective, supplemented and amended as
      required by the Act, in order to permit the Prospectus forming part thereof
      to
      be usable by Holders for a period (the “Shelf Registration Period”) from the
      date the Shelf Registration Statement is declared effective by the Commission
      (or becomes effective in the case of an Automatic Shelf Registration Statement)
      until the earliest of (i) two years from the latest date of original
      issuance of the Notes; (ii) the date when all Registrable Securities shall
      have
      been registered under the Securities Act and disposed of; (iii) the date on
      which all Registrable Securities held by non-affiliates are eligible to be
      sold
      to the public pursuant to Rule 144(k) under the Securities Act;
      and
      (iv) the date upon which there are no Registrable Securities outstanding.
      None of the Company or any of its securityholders (other than the Holders of
      Registrable Securities) shall have the right to include any securities of the
      Company in any Shelf Registration Statement other than Registrable
      Securities.

     

    (d)  The
      Company shall cause the Shelf Registration Statement and the related Prospectus
      and any amendment or supplement thereto, as of the effective date of the Shelf
      Registration Statement or such amendment or supplement, (i) to comply in
      all material respects with the applicable requirements of the Act; and
      (ii) not to contain any untrue statement of a material fact or omit to
      state a material fact required to be stated therein or necessary in order to
      make the statements therein (in the case of the Prospectus, in the light of
      the
      circumstances under which they were made) not misleading.

     

    (e)  The
      Company shall issue a press release through a reputable national newswire
      service announcing the anticipated effective date of the Shelf Registration
      Statement at least 15 Business Days prior to the anticipated effective date
      thereof. In addition, the Company will give notice of its intention to file
      the
      Shelf Registration Statement to the Holders in the same manner as the Company
      would give notice to the holders of the Notes under the Indenture. Each Holder
      of Registrable Securities agrees to deliver a Notice and Questionnaire and
      such
      other information as the Company may reasonably request in writing, if any,
      to
      the Company at least ten Business Days prior to the anticipated effective date
      of the Shelf Registration Statement as announced in the press release. If a
      Holder does not timely complete and deliver a Notice and Questionnaire or
      provide the other information the Company may request, that Holder will not
      be
      named as a selling securityholder in the Prospectus and will not be permitted
      to
      sell its securities under the Shelf Registration Statement. From and after
      the
      effective date of the Shelf Registration Statement, the Company shall use
      commercially reasonable efforts, as promptly as is practicable after the date
      a
      Notice and Questionnaire is delivered, and in any event within five Business
      Days after such date, (i) if required by applicable law, to file with the
      Commission a post-effective amendment to the Shelf Registration Statement;
      and,
      if the Company shall file a post-effective amendment to the Shelf Registration
      Statement, use commercially reasonable efforts to cause such post-effective
      amendment to be declared effective under the Act as promptly as is practicable;
      or to prepare and, if permitted or required by applicable law, to file a
      supplement to the related Prospectus or an amendment or supplement to any
      document incorporated therein by reference or file any other required document
      so that the Holder delivering such Notice and Questionnaire is named as a
      selling securityholder in the Shelf Registration Statement and the related
      Prospectus, and so that such Holder is permitted to deliver such Prospectus
      to
      purchasers of the Registrable Securities in accordance with applicable law;
      provided,
      that
      the Company shall not be required to file more than one post-effective amendment
      in any calendar quarter or to file a supplement or post-effective amendment
      during any Deferral Period; (ii) provide such Holder, upon request, copies
      of any documents filed pursuant to Section 2(e)(i) hereof; and
      (iii) notify such Holder as promptly as practicable after the effectiveness
      under the Act of any post-effective amendment filed pursuant to
      Section 2(e)(i) hereof; provided,
      that if
      such Notice and Questionnaire is delivered during a Deferral Period, the Company
      shall so inform the Holder delivering such Notice and Questionnaire and shall
      take the actions set forth in clauses (i), (ii) and (iii) above upon
      expiration of the Deferral Period in accordance with Section 3(i) hereof.
      Notwithstanding anything contained herein to the contrary, the Company shall
      be
      under no obligation to name any Holder that is not a Notice Holder as a selling
      securityholder in the Shelf Registration Statement or related Prospectus;
provided,
      however,
      that
      any Holder that becomes a Notice Holder pursuant to the provisions of this
      Section 2(e) (whether or not such Holder was a Notice Holder at the
      effective date of the Shelf Registration Statement) shall be named as a selling
      securityholder in the Shelf Registration Statement or related Prospectus in
      accordance with the requirements of this Section 2(e). Each Holder named as
      a selling securityholder in the Prospectus agrees to promptly furnish to the
      Company all information required to be disclosed in order to make information
      previously furnished to the Company by the Holder not materially misleading
      and
      any other information regarding such Holder and the distribution of such
      Holder’s Registrable Securities as the Company may from time to time reasonably
      request in writing.

      amendment or supplement, if any, to the Prospectus included therein (including
      all documents incorporated by reference therein after the initial filing) and
      shall reflect in each such document, when so filed with the Commission, such
      comments as the Initial Purchaser reasonably proposes within three Business
      Days
      of the delivery of such document to the Initial Purchaser; and

     

    (ii)  include
      information regarding the Notice Holders and the methods of distribution they
      have elected for their Registrable Securities provided to the Company in Notices
      and Questionnaires in a timely manner, as provided above, as necessary to permit
      such distribution by the methods specified therein.

     

    (b)  The
      Company shall ensure that:

     

    (i)  the
      Shelf
      Registration Statement and any amendment thereto and any Prospectus forming
      part
      thereof and any amendment or supplement thereto complies in all material
      respects with the Act; and

     

    (ii)  the
      Shelf
      Registration Statement and any amendment thereto does not, when it becomes
      effective, contain an untrue statement of a material fact or omit to state
      a
      material fact required to be stated therein or necessary to make the statements
      therein not misleading.

     

    (c)  The
      Company shall advise the Initial Purchaser (solely with respect to clause (i)
      below), the Notice Holders and any underwriter that has provided in writing
      to
      the Company a telephone or facsimile number and address for notices, and confirm
      such advice in writing, if requested (which notice pursuant to clauses
      (ii)-(v) below shall be accompanied by an instruction to suspend the use of
      the Prospectus until the Company shall have remedied the basis for such
      suspension):

     

    (i)  when
      the
      Shelf Registration Statement and any amendment thereto (other than supplements
      that do nothing more than name Holders and provide information with respect
      thereto or that are required to be filed by the Company under the Exchange
      Act)
      has been filed with the Commission and when the Shelf Registration Statement
      or
      any post-effective amendment thereto has become effective;

     

    (ii)  of
      any
      request by the Commission for any amendment or supplement to the Shelf
      Registration Statement or the Prospectus or for additional information with
      respect thereto;

     

    (iii)  of
      the
      issuance by the Commission of any stop order suspending the effectiveness of
      the
      Shelf Registration Statement or the institution or threatening of any proceeding
      for that purpose, of the issuance by the Commission of a notification of
      objection to the use of the form on which the Registration Statement has been
      filed, and of the happening of any event that causes the Company to become
      an
“ineligible issuer” as defined in Commission Rule 405;

     

    (iv)  of
      the
      receipt by the Company of any notification with respect to the suspension of
      the
      qualification of the Common Stock included therein for sale in any jurisdiction
      or the institution or any written threat of any proceeding for such purpose;
      and

     

    (v)  of
      the
      happening of any event that requires any change in the Shelf Registration
      Statement or the Prospectus so that, as of such date, they (A) do not
      contain any untrue statement of a material fact and (B) do not omit to
      state a material fact required to be stated therein or necessary to make the
      statements therein (in the case of the Prospectus, in the light of the
      circumstances under which they were made) not misleading.

     

    Each
      Holder agrees that, upon receipt of any notice from the Company of the happening
      of any event or the discovery of any facts, each of the kind described in
      clauses (ii) through (v) hereof, such Holder will forthwith discontinue
      disposition of Registrable Securities pursuant to the Prospectus included in
      the
      Shelf Registration Statement until such Holder’s receipt of the copies of the
      supplemented or amended Prospectus contemplated by Section 3(h) hereof or
      written notice from the Company that the Shelf Registration Statement is again
      effective and no amendment or supplement is needed, and, if so directed by
      the
      Company, such Holder will deliver to the Company (at the Company’s expense) all
      copies in such Holder’s possession, other than permanent file copies then in
      such Holder’s possession, of the Prospectus covering such Registrable Securities
      current at the time of receipt of such notice. 

     

    (d)  The
      Company shall use its commercially reasonable efforts to prevent the issuance
      of
      any order suspending the effectiveness of the Shelf Registration Statement
      or
      the qualification of the securities therein for sale in any jurisdiction and,
      if
      issued, to obtain as soon as practicable the withdrawal thereof. The Company
      shall undertake additional actions as required to permit unrestricted resales
      of
      the Common Stock in accordance with the terms and conditions of this
      Agreement.

     

    (e)  Upon
      request, the Company shall furnish to each Notice Holder, without charge, at
      least one copy of the Shelf Registration Statement and any post-effective
      amendment thereto, including all material incorporated therein by reference,
      and, if a Notice Holder so requests in writing, all exhibits thereto (including
      exhibits incorporated by reference therein).

     

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

    (f)  During
      the Shelf Registration Period, the Company shall promptly deliver to each Notice
      Holder and any sales or placement agents or underwriters acting on their behalf,
      without charge, as many copies of the Prospectus (including the preliminary
      Prospectus, if any) included in the Shelf Registration Statement and any
      amendment or supplement thereto as any such person may reasonably request.
      The
      Company consents to the use of the Prospectus or any amendment or supplement
      thereto by each of the foregoing in connection with the offering and sale of
      the
      Registrable Securities in the manner contemplated by the
      Prospectus.

     

    (g)  Prior
      to
      any offering of Common Stock pursuant to the Shelf Registration Statement,
      the
      Company shall use commercially reasonable efforts to arrange for the
      qualification of the Registrable Securities for sale under the laws of such
      jurisdictions as any Notice Holder shall reasonably request in writing and
      shall
      use reasonable best efforts to maintain such qualification in effect so long
      as
      required; provided
      that in
      no event shall the Company be obligated to qualify to do business or as a dealer
      in any jurisdiction where it is not then so qualified or to take any action
      that
      would subject it to taxation or service of process in any jurisdiction where
      it
      is not then so subject.

     

    (h)  Upon
      the
      occurrence of any event contemplated by subsections (c)(ii) through
      (v) above, the Company shall as promptly as practicable (or within the time
      period provided for by Section 3(i) hereof, if applicable) prepare a
      post-effective amendment to the Shelf Registration Statement or an amendment
      or
      supplement to the related Prospectus or file any other required document so
      that, as thereafter delivered to the Initial Purchaser of the Registrable
      Securities included therein, the Prospectus will not include an untrue statement
      of a material fact or omit to state any material fact required to be stated
      therein or necessary to make the statements therein, in the light of the
      circumstances under which they were made, not misleading.

     

    (i)  Upon
      the
      occurrence or existence of any pending corporate development, public filings
      with the Commission or any other material event that, in the reasonable judgment
      of the Company, makes it appropriate to suspend the availability of the Shelf
      Registration Statement and the related Prospectus, the Company shall give notice
      (without notice of the nature or details of such events) to the Notice Holders
      that the availability of the Shelf Registration Statement is suspended and,
      upon
      actual receipt of any such notice, each Notice Holder agrees not to sell any
      Registrable Securities pursuant to the Shelf Registration Statement until such
      Notice Holder’s receipt of copies of the supplemented or amended Prospectus
      provided for in Section 3(h) hereof, or until it is advised in writing by
      the Company that the Prospectus may be used, and has received copies of any
      additional or supplemental filings that are incorporated or deemed incorporated
      by reference in such Prospectus. The period during which the availability of
      the
      Shelf Registration Statement and any Prospectus is suspended (the “Deferral
      Period”) shall not exceed 90 days in any 12-month period. Each Holder shall keep
      confidential any communications received by it from the Company regarding the
      suspension of the use of the Prospectus, except as required by applicable
      law.

     

    (j)  The
      Company shall comply with all applicable rules and regulations of the Commission
      and shall make generally available to its securityholders an earnings statement
      satisfying the provisions of Section 11(a) and Rule 158 of the Act (in
      either case, or such longer period as permitted by the Commission pursuant
      to
      Rule 12b-25 promulgated under the Exchange Act) no later than 45 days after
      the
      end of a 12-month period (or 90 days, if such period is a fiscal year) beginning
      with the first month of the Company’s first fiscal quarter commencing after the
      effective date of the Shelf Registration Statement.

     

    (k)  In
      addition to the Notice and Questionnaire, the Company may require each Holder
      of
      Registrable Securities to be sold pursuant to the Shelf Registration Statement
      to furnish to the Company such information regarding the Holder and the
      distribution of such Registrable Securities as the Company may from time to
      time
      reasonably require for inclusion in the Shelf Registration Statement. The
      Company may exclude from the Shelf Registration Statement the Registrable
      Securities of any Holder that fails to furnish such information within 15 days
      after receiving such request.

     

    (l)  In
      connection with an underwritten offering of the Registrable Securities, and
      subject to Section 6 hereof, the Company shall enter into customary
      agreements (including, if requested, an underwriting agreement in customary
      form) and take all other customary actions in order to expedite or facilitate
      the registration or the underwritten disposition of Registrable Securities,
      and
      in connection therewith, if an underwriting agreement is entered into, cause
      the
      same to contain customary indemnification provisions and
      procedures.

     

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

    (m)  Subject
      to Section 6 hereof, the Company shall:

     

    (i)  make
      reasonably available for inspection during normal business hours and upon prior
      notice by a representative of the Notice Holders of Registrable Securities
      to be
      registered thereunder, any underwriter participating in any disposition pursuant
      to the Shelf Registration Statement, and any attorney, accountant or other
      agent
      retained by the Holders or any such underwriter all relevant financial and
      other
      records and pertinent corporate documents of the Company and its subsidiaries;
      provided
      that
      such persons shall, at the Company’s request, first agree in writing with the
      Company that any information that is designated by the Company in writing as
      confidential at the time of delivery of such information shall be kept
      confidential by such persons and shall be used solely for the purpose of
      exercising rights under this Agreement; and provided,
      further, that the Company shall not be required to disclose any information
      subject to the attorney-client privilege or attorney work product privilege
      if
      and to the extent such disclosure would constitute a waiver of such
      privilege;

     

    (ii)  use
      its
      commercially reasonable efforts to cause the appropriate officers, directors,
      employees, accountants and auditors of the Company to make available for
      inspection during normal business hours all relevant information reasonably
      requested by such Holders or any such underwriter, attorney, accountant or
      agent
      in connection with the Shelf Registration Statement as is customary for similar
      due diligence examinations; provided,
      however,
      that
      the foregoing inspection and information gathering shall be coordinated on
      behalf of the Notice Holders or the Initial Purchaser by one counsel designated
      by and on behalf of such other parties as described in Section 4 hereof;
provided,
      further,
      that
      such persons shall, at the Company’s request, first agree in writing with the
      Company that any information that is designated by the Company in writing as
      confidential at the time of delivery of such information shall be kept
      confidential by such persons and shall be used solely for the purpose of
      exercising rights under this Agreement; and provided,
      further,
      that
      the Company shall not be required to disclose any information subject to the
      attorney-client privilege or attorney work product privilege if and to the
      extent such disclosure would constitute a waiver of such privilege;

     

    (iii)  make
      such
      representations and warranties to the Holders of Registrable Securities
      registered thereunder and the underwriters, if any, in form, substance and
      scope
      as are customarily made by issuers to underwriters in primary underwritten
      offerings and covering matters including, but not limited to, those set forth
      in
      the Purchase Agreement;

     

    (iv)  if
      requested by any Notice Holder in connection with an underwritten offering
      of
      the Registrable Securities, obtain opinions of counsel to the Company in
      customary form addressed to the Managing Underwriters, if any, and each selling
      Holder that is an underwriter;

     

    (v)  obtain
      “comfort” letters and updates thereof from the independent certified public
      accountants of the Company (and, if necessary, any other independent certified
      public accountants of any subsidiary of the Company or of any business acquired
      by the Company for which financial statements and financial data are, or are
      required to be, included in the Shelf Registration Statement), addressed to
      each
      selling Holder of Registrable Securities registered thereunder that is an
      underwriter and the Managing Underwriters, if any, in customary form and
      covering matters of the type customarily covered in “comfort” letters to
      underwriters in connection with similar underwritten offerings; and

     

    (vi)  deliver
      such documents and certificates as may be reasonably requested by the Majority
      Holders or the Managing Underwriters, if any, including those to evidence
      compliance with Section 3(j) hereof and with any customary conditions
      (including without limitation lock-up agreements with directors and officers)
      contained in the underwriting agreement or similar agreement entered into by
      the
      Company in connection with such underwritten offering.

     

    The
      actions set forth in clauses (iii), (iv), (v) and (vi) of this
      paragraph (m) shall be performed in connection with any underwriting or
      similar agreement as and to the extent required thereunder.

     

    (n)  In
      the
      event that any Broker-Dealer shall underwrite any Registrable Securities or
      participate as a member of an underwriting syndicate or selling group or “assist
      in the distribution” (within the meaning of the NASD Rules) thereof, whether as
      a Holder of such Registrable Securities or as an underwriter, a placement or
      sales agent or a broker or dealer in respect thereof, or otherwise, the Company
      shall use its reasonable best efforts to assist such Broker-Dealer in complying
      with the NASD Rules (subject to the same limitations and qualifications
      regarding confidentiality, attorney-client privilege and attorney work product
      privilege described in Section 3(m) above).

     

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

    (o)  The
      Company shall
      use its
      commercially reasonable efforts to take all other steps necessary to effect
      the
      registration of the Registrable Securities covered by the Shelf Registration
      Statement.

     

    4.  Registration
      Expenses.

     

    The
      Company shall bear all expenses incurred in connection with the performance
      of
      its obligations under Sections 2 and 3 hereof and shall reimburse the
      Holders for the reasonable fees and disbursements of one firm or counsel (which,
      if appointed, shall be a nationally recognized law firm experienced in
      securities matters designated by the Majority Holders) to act as counsel for
      the
      Holders in connection therewith. Notwithstanding the foregoing, each Holder
      shall pay all underwriting discounts and commissions, broker fees and
      commissions, and transfer taxes, if any, relating to the sale or disposition
      of
      such Holder’s Securities pursuant to the Shelf Registration
      Statement.

     

    5.  Indemnification
      and Contribution.

     

     (a)
      The
      Company agrees to indemnify and hold harmless each Holder of Registrable
      Securities covered by the Shelf Registration Statement, the Initial Purchaser,
      the directors, officers, employees, Affiliates and agents of each such Holder
      or
      Initial Purchaser and each person who controls any such Holder or Initial
      Purchaser within the meaning of either the Act or the Exchange Act against
      any
      and all losses, claims, damages or liabilities, joint or several, to which
      they
      or any of them may become subject under the Act, the Exchange Act or other
      federal or state statutory law or regulation, at common law or otherwise,
      insofar as such losses, claims, damages or liabilities (or actions in respect
      thereof) arise out of or are based upon any untrue statement or alleged untrue
      statement of a material fact contained in the Shelf Registration Statement
      as
      originally filed or in any amendment thereof, or in any preliminary Prospectus
      or the Prospectus, or in any amendment thereof or supplement thereto, or arise
      out of or are based upon the omission or alleged omission to state therein
      a
      material fact required to be stated therein or necessary to make the statements
      therein (in the case of any preliminary Prospectus or the Prospectus, in the
      light of the circumstances under which they were made) not misleading, and
      agrees to reimburse each such indemnified party, as incurred, for any legal
      or
      other expenses reasonably incurred by it in connection with investigating or
      defending any such loss, claim, damage, liability or action; provided,
      however,
      that
      the Company will not be liable in any such case to the extent that any such
      loss, claim, damage or liability arises out of or is based upon any such untrue
      statement or alleged untrue statement or omission or alleged omission made
      therein in reliance upon and in conformity with written information furnished
      to
      the Company by or on behalf of the party claiming indemnification specifically
      for inclusion therein. This indemnity agreement shall be in addition to any
      liability that the Company may otherwise have to the indemnified
      party.

     

    The
      Company also agrees to indemnify as provided in this Section 5(a) or
      contribute as provided in Section 5(d) hereof to Losses of each
      underwriter, if any, of Registrable Securities registered under the Shelf
      Registration Statement, its directors, officers, employees, Affiliates or agents
      and each person who controls such underwriter on substantially the same basis
      as
      that of the indemnification of the Initial Purchaser and the selling Holders
      provided in this paragraph (a) and shall, if requested by any Holder, enter
      into an underwriting agreement reflecting such agreement, as provided in
      Section 3(l) hereof.

     

    (b)  Each
      Holder of securities covered by the Shelf Registration Statement (including
      the
      Initial Purchaser that is a Holder, in such capacity) severally and not jointly
      agrees to indemnify and hold harmless the Company , each of its directors,
      each
      of its officers, employees, Affiliates and agents of the Company and each person
      who controls the Company within the meaning of either the Act or the Exchange
      Act, to the same extent as the foregoing indemnity from the Company to each
      such
      Holder, but only with reference to written information relating to such Holder
      furnished to the Company by or on behalf of such Holder specifically for
      inclusion in the documents referred to in the foregoing indemnity. This
      indemnity agreement shall be acknowledged by each Notice Holder that is not
      an
      Initial Purchaser in such Notice Holder’s Notice and Questionnaire and shall be
      in addition to any liability that any such Notice Holder may otherwise have
      to
      the Company.

     

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

    (c)  Promptly
      after receipt by an indemnified party under this Section 5 or notice of the
      commencement of any action, such indemnified party will, if a claim in respect
      thereof is to be made against the indemnifying party under this Section 5,
      notify the indemnifying party in writing of the commencement thereof; but the
      failure so to notify the indemnifying party (i) will not relieve the
      indemnifying party from liability under paragraph (a) or (b) above
      unless and to the extent it did not otherwise learn of such action and such
      failure results in the forfeiture by the indemnifying party of any substantial
      rights and defenses; and (ii) will not, in any event, relieve the
      indemnifying party from any obligations to any indemnified party other than
      the
      indemnification obligation provided in paragraph (a) or (b) above. The
      indemnifying party shall be entitled to appoint counsel (including local
      counsel) of the indemnifying party’s choice at the indemnifying party’s expense
      to represent the indemnified party in any action for which indemnification
      is
      sought (in which case the indemnifying party shall not thereafter be responsible
      for the fees and expenses of any separate counsel, other than local counsel
      if
      not appointed by the indemnifying party, retained by the indemnified party
      or
      parties except as set forth below); provided,
      however,
      that
      such counsel shall be reasonably satisfactory to the indemnified party.
      Notwithstanding the indemnifying party’s election to appoint counsel (including
      local counsel) to represent the indemnified party in an action, the indemnified
      party shall have the right to employ separate counsel (including local counsel),
      and the indemnifying party shall bear the reasonable fees, costs and expenses
      of
      such separate counsel if (i) the use of counsel chosen by the indemnifying
      party to represent the indemnified party would present such counsel with a
      conflict of interest; (ii) the actual or potential defendants in, or
      targets of, any such action include both the indemnified party and the
      indemnifying party and the indemnified party shall have reasonably concluded
      that there may be legal defenses available to it and/or other indemnified
      parties that are different from or additional to those available to the
      indemnifying party; (iii) the indemnifying party shall not have employed
      counsel satisfactory to the indemnified party to represent the indemnified
      party
      within a reasonable time after notice of the institution of such action; or
      (iv) the indemnifying party shall authorize the indemnified party to employ
      separate counsel at the expense of the indemnifying party. No
      indemnifying party shall, without the prior written consent of the indemnified
      party, effect any settlement of any pending or threatened action in respect
      of
      which any indemnified party is or could have been a party and indemnity could
      have been sought hereunder by such indemnified party unless such settlement
      (i)
      includes an unconditional release of such indemnified party from all liability
      on any claims that are the subject matter of such action, (ii) does not include
      a statement as to, or an admission of, fault, culpability or a failure to act
      by
      or on behalf of an indemnified party, and (iii) does not include any undertaking
      or obligation to act or to refrain from acting by the indemnified
      party.

     

    (d)  In
      the
      event that the indemnity provided in paragraph (a) or (b) of this
      Section 5 is unavailable to or insufficient to hold harmless an indemnified
      party for any reason, then each applicable indemnifying party shall have a
      joint
      and several obligation to contribute to the aggregate losses, claims, damages
      and liabilities (including legal or other expenses reasonably incurred in
      connection with investigating or defending loss, claim, liability, damage or
      action) (collectively “Losses”) to which such indemnified party may be subject
      in such proportion as is appropriate to reflect the relative benefits received
      by such indemnifying party, on the one hand, and such indemnified party, on
      the
      other hand, from the Shelf Registration Statement which resulted in such Losses.
      If the allocation provided by the immediately preceding sentence is unavailable
      for any reason, the indemnifying party and the indemnified party shall
      contribute in such proportion as is appropriate to reflect not only such
      relative benefits but also the relative fault of such indemnifying party, on
      the
      one hand, and such indemnified party, on the other hand, in connection with
      the
      statements or omissions which resulted in such Losses as well as any other
      relevant equitable considerations. Relative fault shall be determined by
      reference to, among other things, whether any untrue or any alleged untrue
      statement of a material fact or omission or alleged omission to state a material
      fact relates to information provided by the indemnifying party, on the one
      hand,
      or by the indemnified party, on the other hand, the intent of the parties and
      their relative knowledge, access to information and opportunity to correct
      or
      prevent such untrue statement or omission. The parties agree that it would
      not
      be just and equitable if contribution were determined by pro rata allocation
      (even if the Holders were treated as one entity for such purpose) or any other
      method of allocation which does not take account of the equitable considerations
      referred to above. Notwithstanding any other provision of this Section 5(d),
      the
      Holders shall not be required to contribute any amount in excess of the amount
      by which the net proceeds received by such Holders from the sale of the
      Registrable Securities pursuant to the Shelf Registration Statement exceeds
      the
      amount of damages which such Holders have otherwise been required to pay by
      reason of such untrue or alleged untrue statement or omission or alleged
      omission. Notwithstanding the provisions of this paragraph (d), no person
      guilty of fraudulent misrepresentation (within the meaning of Section 11(f)
      of the Act) shall be entitled to contribution from any person who was not guilty
      of such fraudulent misrepresentation. For purposes of this Section 5, each
      person who controls a Holder within the meaning of either the Act or the
      Exchange Act and each director, officer, employee and agent of such Holder
      shall
      have the same rights to contribution as such Holder, and each person who
      controls the Company within the meaning of either the Act or the Exchange Act,
      each officer of the Company and each director, employee or agent of the Company
      shall have the same rights to contribution as the Company , subject in each
      case
      to the applicable terms and conditions of this paragraph (d).

     

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

    (e)  The
      provisions of this Section 5 shall remain in full force and effect,
      regardless of any investigation made by or on behalf of any Holder or the
      Company or any of the indemnified persons referred to in this Section 5,
      and shall survive the sale by a Holder of securities covered by the Shelf
      Registration Statement.

     

    6.  Underwritten
      Registrations.

     

     (a)
      In no
      event will the method of distribution of Registrable Securities take the form
      of
      an underwritten offering without the prior written consent of the
      Company.

     

    (b)  If
      any
      shares of Registrable Securities covered by the Shelf Registration Statement
      are
      to be sold in an underwritten offering, the Managing Underwriters shall be
      selected by the Company, subject to the prior written consent of the Majority
      Holders, which consent shall not be unreasonably withheld.

     

    (c)  No
      person
      may participate in any underwritten offering pursuant to the Shelf Registration
      Statement unless such person (i) agrees to sell such person’s Registrable
      Securities on the basis reasonably provided in any underwriting arrangements
      approved by the persons entitled hereunder to approve such arrangements; and
      (ii) completes and executes all questionnaires, powers of attorney,
      indemnities, underwriting agreements and other documents reasonably required
      under the terms of such underwriting arrangements.

     

    7.  Registration
      Defaults.

     

    If
      any of
      the following events shall occur, then the Company shall pay additional interest
      (the “Additional Interest”) to the Holders as follows:

     

    (a)  if
      the
      Shelf Registration Statement is not filed with the Commission on or prior to
      the
      120th
      day
      following the Closing Date, then commencing on the 121st
      day
      after the Closing Date, Additional Interest shall accrue on the aggregate
      outstanding principal amount of the Notes, at a rate of 0.25% per annum for
      the first 90 days from and including such 121st
      day and
      0.50% per annum thereafter; or

     

    (b)  if
      the
      Shelf Registration Statement is not declared effective by the Commission (or
      has
      not become effective in the case of an Automatic Shelf Registration Statement)
      on or prior to the 180th
      day
      following the Closing Date, then commencing on the 181st
      day
      after the Closing Date, Additional Interest shall accrue on the aggregate
      outstanding principal amount of the Notes, at a rate of 0.25% per annum for
      the first 90 days from and including such 181st
      day and
      0.50% per annum thereafter; or

     

    (c)  if
      the
      Shelf Registration Statement has been declared or become effective but ceases
      to
      be effective or usable for the offer and sale of the Registrable Securities
      (without being succeeded immediately by an effective replacement shelf
      registration statement), or the Shelf Registration Statement or Prospectus
      contained therein ceases to be usable in connection with the resales of
      Registrable Securities for a period of time which exceeds 120 days in the
      aggregate in any consecutive 12-month period because either (i) any event occurs
      as a result of which the Prospectus forming part of such Shelf Registration
      Statement would include any untrue statement of a material fact or omit to
      state
      any material fact necessary to make the statements therein in the light of
      the
      circumstances under which they were made not misleading, (ii) it shall be
      necessary to amend such Shelf Registration Statement or supplement the related
      Prospectus to comply with the Act or Exchange Act or the respective rules
      thereunder, or (iii) the occurrence or existence of any pending corporate
      development or other material event with respect to us or a public filing with
      the Commission that, in the Company’s reasonable discretion, makes it
      appropriate to suspend the availability of a Shelf Registration Statement and
      the related prospectus, then Additional Interest shall accrue on the aggregate
      outstanding principal amount of the Notes at a rate of 0.25% per annum for
      the first 90 days from and including the day following such 91st
      day and
      0.50% per annum thereafter; 

     

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

    provided,
      however,
      that
      (1) upon the filing of the Shelf Registration Statement (in the case of
      paragraph (a) above), (2) upon the effectiveness of the Shelf
      Registration Statement (in the case of paragraph (b) above), or
      (3) upon such time as the Shelf Registration Statement which had ceased to
      remain effective or usable for resales again becomes effective and usable for
      resales (in the case of paragraph (c) above), the Additional Interest shall
      cease to accrue.

     

    Any
      amounts of Additional Interest due pursuant to this Section 7 will be
      payable in cash on the next succeeding interest payment date to Holders entitled
      to receive such Additional Interest on the relevant record dates for the payment
      of interest. If any Note ceases to be outstanding during any period for which
      Additional Interest is accruing, the Company will prorate the Additional
      Interest payable with respect to such Note. Upon the cure of all Registration
      Defaults then continuing, the accrual of Additional Interest will automatically
      cease and the interest rate borne by the Notes will revert to the original
      interest rate at such time.

     

    If
      Additional Interest would be payable because of more than one Registration
      Default, but at a rate of 0.25% per annum under one Registration Default
      and at a rate of 0.50% per annum under the other, then the Additional
      Interest rate shall be the higher rate of 0.50% per annum. Other than the
      Company’s obligation to pay Additional Interest in accordance with this
      Section 7, the Company will not have any liability for damages with respect
      to a Registration Default.

     

    Notwithstanding
      any provision in this Agreement, in no event shall Additional Interest accrue
      to
      holders of Common Stock issued upon conversion of the Notes. 

     

    8.  No
      Inconsistent Agreements.

     

    The
      Company has not entered into, and agrees not to enter into, any agreement with
      respect to its securities that is inconsistent with the registration rights
      granted to the Holders herein.

     

    9.  Rule
      144A and Rule 144.

     

    So
      long
      as any Registrable Securities remain outstanding, the Company shall use its
      commercially reasonable efforts to file the reports required to be filed by
      it
      under Rule 144A(d)(4) under the Act and the Exchange Act in a timely manner
      and,
      if at anytime the Company is not required to file such reports, it will, upon
      the written request of any Holder of Registrable Securities, make publicly
      available information necessary to permit sales of such Holder’s Registrable
      Securities pursuant to Rules 144 and 144A of the Act. The Company covenants
      that
      it will use its commercially reasonable efforts to take such further action
      as
      any Holder of Registrable Securities may reasonably request, all to the extent
      required from time to time to enable such Holder to sell Registrable Securities
      without registration under the Act within the limitation of the exemptions
      provided by Rules 144 and 144A (including, without limitation, the requirements
      of Rule 144A(d)(4)). Upon the written request of any Holder of Registrable
      Securities, the Company shall deliver to such Holder a written statement as
      to
      whether it has complied with such requirements, unless such statement has been
      included in the Company’s most recent report filed with the Commission pursuant
      to Section 13 or Section 15(d) of the Exchange Act. Notwithstanding the
      foregoing, nothing in this Section 9 shall be deemed to require the Company
      to register any of its securities pursuant to the Exchange Act.

     

    10.  Listing.

     

     So
      long
      as any Registrable Securities are outstanding, the Company shall use its
      commercially reasonable efforts to maintain the approval of the Registrable
      Securities for listing on the Nasdaq Global Market or such other exchange or
      trading market as the Common Stock is then listed.

     

    11.  Amendments
      and Waivers.

     

    The
      provisions of this Agreement may not be amended, qualified, modified or
      supplemented, and waivers or consents to departures from the provisions hereof
      may not be given, unless the Company has obtained the written consent of the
      Majority Holders; provided
      that,
      with respect to any matter that directly or indirectly affects the rights of
      the
      Initial Purchaser (in its capacity as such) hereunder, the Company shall obtain
      the written consent of the Initial Purchaser; provided,
      however,
      that no
      consent is necessary from any Holders in the event that this Agreement is
      amended, modified or supplemented for the purpose of curing any ambiguity,
      defect or inconsistency that does not adversely affect the rights of Holders;
      and provided,
      further,
      that
      the provisions of this Article 11 may not be amended, qualified, modified or
      supplemented, and waivers or consents to departures from the provisions hereof
      may not be given, unless the Company has obtained the written consent of the
      Initial Purchaser and each Holder. Without the consent of the Holder of each
      Note, no modification may change the provisions relating to the payment of
      Additional Interest.

     

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

    12.  Notices.

     

    All
      notices and other communications provided for or permitted hereunder shall
      be
      made in writing by hand-delivery, first-class mail, telex, telecopier or air
      courier guaranteeing overnight delivery:

     

    (a)  if
      to a
      Holder, at the most current address given by such holder to the Company in
      accordance with the provisions of the Notice and Questionnaire;

     

    (b)  if
      to the
      Initial Purchaser, initially at the address or addresses set forth in the
      Purchase Agreement; and

     

    (c)  if
      to the
      Company,
      initially at its address set forth in the Purchase Agreement.

     

    All
      such
      notices and communications shall be deemed to have been duly given when
      received.

     

    The
      Initial Purchaser or the Company by notice to the other parties may designate
      additional or different addresses for subsequent notices or
      communications.

     

    Notwithstanding
      the foregoing, notices given to Holders holding Notes in book-entry form may
      be
      given through the facilities of DTC or any successor depository.

     

    13.  Remedies.

     

    Each
      Holder, in addition to being entitled to exercise all rights provided to it
      herein or in the Purchase Agreement or granted by law, including recovery of
      liquidated or other damages, will be entitled to specific performance of its
      rights under this Agreement. The Company agrees that monetary damages would
      not
      be adequate compensation for any loss incurred by reason of a breach of the
      provisions of this Agreement and hereby agrees to waive in any action for
      specific performance the defense that a remedy at law would be
      adequate.

     

    14.  Successors.

     

    This
      Agreement shall inure to the benefit of and be binding upon the parties hereto,
      their respective successors and assigns, including, without the need for an
      express assignment or any consent by the Company thereto, subsequent Holders
      of
      Registrable Securities, and the indemnified persons referred to in
      Section 5 hereof. The Company hereby agrees to extend the benefits of this
      Agreement to any Holder of Registrable Securities, and any such Holder may
      specifically enforce the provisions of this Agreement as if an original party
      hereto.

     

    15.  Counterparts.

     

    This
      Agreement may be signed in one or more counterparts, each of which shall
      constitute an original and all of which together shall constitute one and the
      same agreement.

     

    16.  Headings.

     

    The
      section headings used herein are for convenience only and shall not affect
      the
      construction hereof.

     

    17.  Applicable
      Law.

     

    This
      Agreement shall be governed by and construed in accordance with the laws of
      the
      State of New York applicable to contracts made and to be performed in the State
      of New York. The parties hereto each hereby waive any right to trial by jury
      in
      any action, proceeding or counterclaim arising out of or relating to this
      Agreement.

     

    18.  Severability.

     

    In
      the
      event that any one of more of the provisions contained herein, or the
      application thereof in any circumstances, is held invalid, illegal or
      unenforceable in any respect for any reason, the validity, legality and
      enforceability of any such provision in every other respect and of the remaining
      provisions hereof shall not be in any way impaired or affected thereby, it
      being
      intended that all of the rights and privileges of the parties shall be
      enforceable to the fullest extent permitted by law.

     

    19.  Notes
      Held by the Company, etc.

     

    Whenever
      the consent or approval of Holders of a specified percentage of principal amount
      of Notes is required hereunder, Notes held by the Company or its Affiliates
      (other than subsequent Holders of Notes if such subsequent Holders are deemed
      to
      be Affiliates solely by reason of their holdings of such Notes) shall not be
      counted in determining whether such consent or approval was given by the Holders
      of such required percentage.

      the
      foregoing is in accordance with your understanding of our agreement, please
      sign
      and return to us the enclosed duplicate hereof, whereupon this letter and your
      acceptance shall represent a binding agreement by and between the Company and
