THE UNDERSIGNED SHAREHOLDERS OF

AND:

Lusora Healthcare Systems Inc.,
a Company incorporated under

  the laws of the Sate of Nevada, with an office at 2802 FlintrockTrace, Suite

(“LHCS”)

WHEREAS:

	A. 	
      The Privco Shareholders are the owners of 30,075,000
      common shares in the capital of Lusora, Inc. (collectively, the
      “Property”), a corporation existing under the laws of the State of Nevada;
      and,

	 	 
	B. 	
      The Privco Shareholders have agreed to exchange and LHCS
      has agreed to purchase the Property on the terms and conditions set forth
      in this share exchange agreement (“Agreement”).

NOW THEREFORE THIS AGREEMENT WITNESSES THAT in consideration of
the premises and the respective covenants and agreements herein contained, the
parties hereto covenant and agree as follows:

	1. 	
      The Privco Shareholders hereby exchanges and LHCS hereby
      purchases the Property for and at a price equal to the fair market value
      of the Property at the date of this Agreement (the “Purchase
    Price”).

	 	 
	2. 	
      In consideration for the transfer of each common share in
      the capital of Lusora Inc. by the Privco Shareholders to LHCS, LHCS agrees
      to issue to the Privco Shareholders one common share in the capital of
      LHCS, with an aggregate value equal to the Purchase Price.

	 	 
	3. 	
      The Privco Shareholders represent and warrant that they
      are the beneficial owners of the Property and that the Property is free
      and clear of all encumbrances of every nature and kind whatsoever and is
      freely saleable and transferable to LHCS.

- 2 -

	4. 	 Notwithstanding anything herein contained,
        the parties agree that it is their intention that the Purchase Price be
        an amount equal to the fair market value of the Property on the closing
        date (“Closing Date”) of the purchase and exchange of the Property
        (the “Transaction”).

	 	 	 	 
	5. 	 If at any time after the closing date of the
        Transaction contemplated by this Agreement:

	 	 	 	 
		(a) 	 the parties determine that the fair market
        value of the Property is different from the Purchase Price therefor as
        herein set out; or,

	 	 	 	 
		(b) 	 the competent taxing authority issues or proposes
        to issue any assessment or re-assessment of tax for any person on the
        basis of a determination that the fair market value of the Property is
        different from the Purchase Price, and the parties agree with such determination,
        or for the purposes of administering the applicable tax statute and determining
        the income tax consequence of the transaction herein set out, a determination
        of the fair market value is finally determined by a tribunal or Court
        of competent jurisdiction to be other than the Purchase Price;

	 	 	 	 
		 the parties will amend this Agreement retroactively
        to the effective date hereof and adjust the Purchase Price to ensure that
        the intention set out in Section 4 of this Agreement is met, but in no
        event will such elected amount be an amount greater than the fair market
        value thereof. Any adjustment to the Purchase Price pursuant to this Section
        5 will be carried out between the parties as agreed at the time such adjustment
        is to be made.

	 	 	 	 
	6. 	 Each Privco Shareholder represents and warrants
        that:

	 	 	 	 
		(a) 	 he has been advised to consult his own legal,
        tax and other advisors with respect to the merits and risks of an investment
        in the common shares in the capital of LHCS and with respect to applicable
        resale restrictions;

	 	 	 	 
		(b) 	 he is solely responsible (and LHCS is not
        in any way responsible) for compliance with:

			(ii) 	 applicable resale restrictions,

	 	 	 	 
			 in connection with the common shares in
        the capital of LHCS hereunder.

      issuable on conversion of Securities shall be substantially in the proportion
      which the total number of shares of such class resulting from all such

      2.01.  Form
      and Dating.
      The
      Securities and the Trustee’s certificate of authentication shall be
      substantially in the respective forms set forth in Exhibit A, which Exhibit
      is
      incorporated in and made part of this Indenture. The Securities may have

      quotation system rule or regulation or usage. The Company shall provide any
      such
      notations, legends or endorsements to the Trustee in writing. Each Security
      shall be dated the date of its authentication. The Securities are being offered
      and sold by the Company pursuant to a Securities Purchase Agreement dated
      November 16, 2006 (the “Purchase Agreement”) among the Company and the
      Purchasers.

    (a)  Restricted
      Global Securities.
      All of
      the Securities are initially being offered and sold to qualified institutional
      buyers as defined in Rule 144A (collectively, “QIBs” or individually, each a
“QIB”) in reliance upon a private placement exemption from registration under
      the Securities Act and shall be issued initially in the form of one or more
      Restricted Global Securities, which shall be deposited on behalf of the
      purchasers of the securities represented thereby with the Trustee, at its
      Corporate Trust Office, as custodian for the depositary, The Depository Trust
      Company (“DTC”, and such depositary, or any successor thereto, being hereinafter
      referred to as the “Depositary”), and registered in the name of its nominee,
      Cede & Co. (or any successor thereto), for the accounts of participants in
      the Depositary, duly executed by the Company and authenticated by the Trustee
      as
      hereinafter provided. The aggregate principal amount of the Restricted Global
      Securities may from time to time be increased or decreased by adjustments made
      on the records of the Securities Custodian as hereinafter provided, subject
      in
      each case to compliance with the Applicable Procedures. 

     

    (b)  Global
      Securities In General.
      Each
      Global Security shall represent such of the outstanding Securities as shall
      be
      specified therein and each shall provide that it shall represent the aggregate
      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 replacements,
      exchanges, purchases, redemptions, or conversions of such Securities. Any
      adjustment of the aggregate principal amount of a Global Security to reflect
      the
      amount of any increase or decrease in the amount of outstanding Securities
      represented thereby shall be made by the Trustee in accordance with instructions
      given by the Holder thereof as required by Section 2.12 and shall be made on
      the
      records of the Trustee and the Depositary.

     

    Members
      of, or participants in, the Depositary (“Agent Members”) 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. Notwithstanding the foregoing,
      nothing herein shall (1) 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 (2) impair, as between the
      Depositary and its Agent Members, the operation of customary practices governing
      the exercise of the rights of a Holder of any Security. 

     

    (c)  Book
      Entry Provisions.
      The
      Company shall execute and the Trustee shall, in accordance with this Section
      2.01(c), authenticate and deliver initially one or more Global Securities that
      (1) shall be registered in the name of the Depositary or its nominee, (2) shall
      be delivered by the Trustee to the Depositary or pursuant to the Depositary’s
      instructions and (3) shall bear legends substantially to the following
      effect:

     

    “UNLESS
      THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY
      TRUST COMPANY TO THE COMPANY OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE
      OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE &
CO. OR IN SUCH OTHER NAME 

     

    
      
        
        

      

      
        11

        
          

        

      

      
        
        

      

    

    AS
      IS
      REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY (AND
      ANY PAYMENT HEREON IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS
      REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY),
      ANY
      TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON
      IS WRONGFUL SINCE THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST
      HEREIN. THIS SECURITY IS A GLOBAL SECURITY WITHIN THE MEANING OF THE INDENTURE
      HEREINAFTER REFERRED TO AND IS REGISTERED IN THE NAME OF A DEPOSITARY OR A
      NOMINEE THEREOF. THIS SECURITY IS EXCHANGEABLE FOR SECURITIES REGISTERED IN
      THE
      NAME OF A PERSON OTHER THAN THE DEPOSITARY OR ITS NOMINEE ONLY IN THE LIMITED
      CIRCUMSTANCES DESCRIBED IN THE INDENTURE AND, UNLESS AND UNTIL IT IS EXCHANGED
      IN WHOLE OR IN PART FOR SECURITIES IN DEFINITIVE FORM, THIS 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.”

     

    Section
      2.02.  Execution
      and Authentication.

     

    (a)  The
      aggregate principal amount of Securities which may be authenticated and
      delivered under this Indenture is limited to $125,000,000 aggregate principal
      amount, except as provided in Sections 2.06 and 2.07.

     

    (b)  An
      Officer shall sign the Securities for the Company by manual or facsimile
      signature. Typographic and other minor errors or defects in any such facsimile
      signature shall not affect the validity or enforceability of any Security that
      has been authenticated and delivered by the Trustee.

     

    (c)  If
      an
      officer 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. 

     

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

     

    (e)  The
      Trustee shall authenticate and make available for delivery Securities for
      original issue in the aggregate principal amount of up to $125,000,000 upon
      receipt of a written order or orders of the Company signed by an Officer of
      the
      Company (a “Company Order”). The Company order shall specify the amount of
      Securities to be authenticated, shall provide that all such securities will
      be
      represented by a Restricted Global Security and the date on which each original
      issue of Securities is to be authenticated. 

     

    
      
        
        

      

      
        12

        
          

        

      

      
        
        

      

    

    (f)  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. 

     

    (g)  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
      2.03.  Registrar,
      Paying Agent and Conversion Agent.

     

    (a)  The
      Company shall maintain one or more offices or agencies where Securities may
      be
      presented for registration of transfer or for exchange (each, a “Registrar”),
      one or more offices or agencies where Securities may be presented for payment
      (each, a “Paying Agent”), one or more offices or agencies where Securities may
      be presented for conversion (each, a “Conversion Agent”) and one or more offices
      or agencies where notices and demands to or upon the Company in respect of
      the
      Securities and this Indenture may be served. The Company will at all times
      maintain a Paying Agent, Conversion Agent, Registrar 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 in the Borough of Manhattan, The City of New
      York. One of the Registrars (the “Primary Registrar”) shall keep a register of
      the Securities and of their transfer and exchange.

     

    (b)  The
      Company shall enter into an appropriate agency agreement with any Agent not
      a
      party to this Indenture, provided that the Agent may be an Affiliate of the
      Trustee. 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, 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 (except for the purposes of
      Section 5.01 and Article 9).

     

    (c)  The
      Company hereby initially designates the Trustee as Paying Agent, Registrar,
      Securities Custodian and Conversion Agent, and initially designates the
      Corporate Trust Office of the Trustee as an office or agency where notices
      and
      demands to or upon the Company in respect of the Securities and this Indenture
      shall be served.

     

    Section
      2.04.  Paying
      Agent to Hold Money in Trust.

     

    Prior
      to
      12:00 p.m. (noon), New York City time, on each due date of the payment of
      principal of, or interest on, any Securities, the Company shall deposit with
      the
      Paying Agent a sum sufficient to pay such principal or interest so becoming
      due.
      Subject to Section 9.02, a Paying Agent shall hold in trust for the benefit
      of
      Holders of Securities or the Trustee all money held by the Paying Agent for
      the
      payment of principal of, or interest on, the Securities, and shall notify the
      Trustee of any failure by the Company (or any other obligor on the Securities)
      to make any such payment. If the Company or an Affiliate of the Company acts
      as
      Paying Agent, it shall, before 12:00 p.m. (noon), New York City time, on each
      due date of the principal of, or interest 

     

    
      
        
        

      

      
        13

        
          

        

      

      
        
        

      

    

    on,
      any
      Securities, segregate the money and hold it as a separate trust fund. The
      Company at any time may require a Paying Agent to pay all money held by it
      to
      the Trustee, and the Trustee may at any time during the continuance of any
      Default, upon written request to a Paying Agent, require such Paying Agent
      to
      pay forthwith to the Trustee all sums so held in trust by such Paying Agent.
      Upon doing so, the Paying Agent (other than the Company) shall have no further
      liability for the money.

     

    Section
      2.05.  Lists
      of Holders of Securities.

     

    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 Holders of
      Securities. If the Trustee is not the Primary 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 in such form and as of
      such
      date as the Trustee may reasonably require of the names and addresses of Holders
      of Securities.

     

    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
      be duly endorsed or accompanied by an assignment form and, if applicable, a
      transfer certificate each in the form included in the form of Security attached
      as Exhibit A hereto, and completed in a manner satisfactory to the Registrar
      and
      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 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 or other governmental charge that may be imposed in relation
      thereto; provided that this sentence shall not apply to any exchange pursuant
      to
      Section 2.10, 2.12(a), 3.06, 4.02(e) or 10.05.

     

    (b)  Neither
      the Company, any Registrar nor the Trustee shall be required to exchange or
      register a transfer of (1) any Securities for a period of 15 days next preceding
      mailing of a notice of Securities to be redeemed, or (2) any Securities or
      portions thereof in respect of which a Fundamental Change Purchase Notice has
      been delivered and not withdrawn by the Holder thereof (except, in the case
      of
      the purchase of a Security in part, the portion thereof not to be
      purchased).

     

    (c)  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.

     

    
      
        
        

      

      
        14

        
          

        

      

      
        
        

      

    

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

     

    (e)  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 certificates and other documentation or evidence as are
      expressly required by, and to do so if and when expressly required by the terms
      of, this Indenture, and to examine the same to determine substantial compliance
      as to form with the express requirements hereof.

     

    Section
      2.07.  Replacement
      Securities.

     

    (a)  If
      any
      mutilated Security is surrendered to the Company, a Registrar or the Trustee,
      and the Company, a Registrar and the Trustee receive evidence to their
      satisfaction of the destruction, loss or theft of any Security, and there is
      delivered to the Company, the applicable Registrar and the Trustee such security
      or indemnity as will be 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 purchaser, the Company shall execute,
      and upon its written request the Trustee shall 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.

     

    (b)  If
      any
      such mutilated, destroyed, lost or stolen Security has become or is about to
      become due and payable, or is about to be purchased by the Company pursuant
      to
      Article 3, or converted pursuant to Article 4, the Company in its discretion
      may, instead of issuing a new Security, pay, purchase or convert such Security,
      as the case may be. 

     

    (c)  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 or other governmental charge
      that may be imposed in relation thereto as a 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. 

     

    (d)  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 hereunder.

     

    (e)  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.

     

    (a)  Securities
      outstanding at any time are all Securities authenticated by the Trustee, except
      for those canceled by it, those purchased pursuant to Article 3, those converted
      pursuant to Article 4, those delivered to the Trustee for cancellation or
      surrendered for transfer or exchange and those described in this Section 2.08
      as
      not outstanding. 

     

    (b)  If
      a
      Security is replaced pursuant to Section 2.07, it ceases to be outstanding
      unless the Company receives proof satisfactory to it that the replaced Security
      is held by a bona fide purchaser. 

     

    (c)  If
      a
      Paying Agent (other than the Company or an Affiliate of the Company) holds
      in
      respect of the outstanding Securities on a Fundamental Change Purchase Date
      or
      the Final Maturity Date money sufficient to pay the principal of (including
      premium, if any), accrued interest and Additional Interest, if any, on
      Securities (or portions thereof) payable on that date, then on and after such
      Fundamental Change Purchase Date or Final Maturity Date, as the case may be,
      such Securities (or portions thereof, as the case may be) shall cease to be
      outstanding and cash interest and Additional Interest, if any, on them shall
      cease to accrue.

     

    (d)  Subject
      to the restrictions contained in Section 2.09, a Security does not cease to
      be
      outstanding 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 concurred in any notice, 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, except that, for purposes
      of determining whether the Trustee shall be protected in relying on any such
      notice, direction, waiver or consent, only Securities which a Trust Officer
      of
      the Trustee with responsibility for this Indenture 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 the Company or any other obligor on the Securities
      or
      any Affiliate of the Company or of such other obligor.

     

    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
      with the consent of the Trustee considers appropriate for temporary Securities.
      Without unreasonable delay, the Company shall prepare and the Trustee shall
      authenticate and deliver definitive Securities in exchange for temporary
      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 or conversion. The Trustee and no one else shall cancel,
      in
      accordance with its standard procedures, all Securities surrendered for
      transfer, exchange, purchase, payment, conversion or cancellation and shall
      dispose of the cancelled Securities in accordance with its customary procedures
      or deliver the canceled Securities to the Company. 

     

    Section
      2.12.  Legend;
      Additional Transfer and Exchange Requirements.

     

    (a)  If
      Securities are issued upon the transfer, exchange or replacement of Securities
      subject to restrictions on transfer and bearing the legends set forth on the
      forms of Securities attached as Exhibit A (collectively, the “Legend”), or if a
      request is made to remove the Legend on a Security, the Securities so issued
      shall bear the Legend, or the Legend shall not be removed, as the case may
      be,
      unless there is delivered to the Company and the Registrar such satisfactory
      evidence, which shall include an Opinion of Counsel if requested by the Company
      or such Registrar, as may be reasonably required by the Company and the
      Registrar, that neither the Legend nor the restrictions on transfer set forth
      therein are required to ensure that transfers thereof comply with the provisions
      of Rule 144A or Rule 144 under the Securities Act or that such Securities are
      not “restricted” within the meaning of Rule 144 under the Securities Act;
      provided that no such evidence need be supplied in connection with the sale
      of
      such Security pursuant to a registration statement that is effective at the
      time
      of such sale. Upon (1) provision of such satisfactory evidence if requested
      or
      (2) notification by the Company to the Trustee and Registrar of the sale of
      such
      Security pursuant to a registration statement that is effective at the time
      of
      such sale, the Trustee, at the written direction of the Company, shall
      authenticate and deliver a Security that does not bear the Legend. If the Legend
      is removed from the face of a Security and the Security is subsequently held
      by
      an Affiliate of the Company, the Legend shall be reinstated. 

     

    (b)  A
      Global
      Security may not be transferred, in whole or in part, to any Person other than
      the Depositary or a nominee or any successor thereof, and no such transfer
      to
      any such other Person may be registered; provided that the foregoing shall
      not
      prohibit any transfer of a Security that is issued in exchange for a Global
      Security but is not itself a Global Security. No transfer of a Security to
      any
      Person shall be effective under this Indenture or the Securities unless and
      until such Security has been registered in the name of such Person.
      Notwithstanding any other provisions of this Indenture or the Securities,
      transfers of a Global Security, in whole or in part, shall be made only in
      accordance with this Section 2.12.

     

    (c)  Subject
      to Section 2.12(b) and in compliance with Section 2.12(d), every Security shall
      be subject to the restrictions on transfer provided in the Legend. Whenever
      any
      Restricted Security other than a Restricted Global Security is presented or
      surrendered for registration of transfer or in exchange for a Security
      registered in a name other than that of the Holder, such Security must be
      accompanied by a certificate in substantially the form set forth in Exhibit
      A,
      dated the date of such surrender and signed by the Holder of such Security,
      as
      to compliance with such restrictions on transfer. The Registrar shall not be
      required to accept for such 

     

    
      
        
        

      

      
        17

        
          

        

      

      
        
        

      

    

    registration
      of transfer or exchange any Security not so accompanied by a properly completed
      certificate. 

     

    (d)  The
      restrictions imposed by the Legend upon the transferability of any Security
      shall cease and terminate when such Security has been sold pursuant to an
      effective registration statement under the Securities Act or transferred in
      compliance with Rule 144 under the Securities Act (or any successor provision
      thereto) or, if earlier, upon the expiration of the holding period applicable
      to
      sales thereof under Rule 144(k) under the Securities Act (or any successor
      provision). Any Security as to which such restrictions on transfer shall have
      expired in accordance with their terms or shall have terminated may, upon a
      surrender of such Security for exchange to the Registrar in accordance with
      the
      provisions of this Section 2.12 (accompanied, in the event that such
      restrictions on transfer have terminated by reason of a transfer in compliance
      with Rule 144 or any successor provision, by, if requested by the Company or
      the
      Registrar, an Opinion of Counsel reasonably acceptable to the Company and the
      Registrar and addressed to the Company and the Registrar, to the effect that
      the
      transfer of such Security has been made in compliance with Rule 144 or such
      successor provision), be exchanged for a new Security, of like tenor and
      aggregate principal amount, which shall not bear the restrictive Legend. The
      Company shall inform the Trustee of the effective date of any registration
      statement registering the offer and sale of the Securities under the Securities
      Act. The Trustee shall not be liable for any action taken or omitted to be taken
      by it in good faith in accordance with the aforementioned Opinion of Counsel
      or
      registration statement.

     

    As
      used
      in Sections 2.12(c) and (d), the term “transfer” encompasses any sale, pledge,
      transfer, hypothecation or other disposition of any Security.

     

    (e)  The
      provisions below shall apply only to Global Securities:

     

    (1)  Each
      Global Security authenticated under this Indenture shall be registered in the
      name of the Depositary or a nominee thereof and delivered to such Depositary
      or
      a nominee thereof or custodian therefor, and each such Global Security shall
      constitute a single Security for purposes of this Indenture. 

     

    (2)  Notwithstanding
      any other provisions of this Indenture or the Securities, a Global Security
      shall not be exchanged in whole or in part for a Security registered, and no
      transfer of a Global Security in whole or in part shall be registered in the
      name of any Person other than the Depositary or one or more nominees thereof;
      provided that a Global Security may be exchanged for securities registered
      in
      the names of any person designated by the Depositary in the event that (A)
      the
      Depositary has notified the Company that it is unwilling or unable to continue
      as Depositary for such Global Security or such Depositary has ceased to be
      a
“clearing agency” registered under the Exchange Act, and a successor Depositary
      is not appointed by the Company within 90 days after receiving such notice
      or
      becoming aware that the Depositary has ceased to be a “clearing agency,” or (B)
      an Event of Default has occurred and is continuing with respect to the
      Securities. Any Global Security exchanged pursuant to subclause (A) above shall
      be so exchanged in whole and not in part, and any Global Security exchanged
      pursuant to subclause (B) above may be exchanged in whole or from time to time
      in part as directed by the Depositary. Any Security issued in exchange for
      a
      Global Security or any portion 

     

    
      
        
        

      

      
        18

        
          

        

      

      
        
        

      

    

    thereof
      shall be a Global Security; provided further that any such Security so issued
      that is registered in the name of a Person other than the Depositary or a
      nominee thereof shall not be a Global Security.

     

    (3)  Securities
      issued in exchange for a Global Security or any portion thereof shall be issued
      in definitive, fully registered form, without interest coupons, shall have
      an
      aggregate principal amount equal to that of such Global Security or portion
      thereof to be so exchanged, shall be registered in such names and be in such
      authorized denominations as the Depositary shall designate and shall bear the
      applicable legends provided for herein. Any Global Security to be exchanged
      in
      whole shall be surrendered by the Depositary to the Trustee, as Registrar.
      With
      regard to any Global Security to be exchanged in part, either such Global
      Security shall be so surrendered for exchange or, if the Trustee is acting
      as
      custodian for the Depositary or its nominee with respect to such Global
      Security, the principal amount thereof shall be reduced, by an amount equal
      to
      the portion thereof to be so exchanged, by means of an appropriate adjustment
      made on the records of the Trustee. Upon any such surrender or adjustment,
      the
      Trustee shall authenticate and deliver the Security issuable on such exchange
      to
      or upon the order of the Depositary or an authorized representative thereof.
      

     

    (4)  Subject
      to clause (6) of this Section 2.12(e), the registered Holder may grant proxies
      and otherwise authorize any Person, including Agent Members and Persons that
      may
      hold interests through Agent Members, to take any action which a Holder is
      entitled to take under this Indenture or the Securities. 

     

    (5)  In
      the
      event of the occurrence of any of the events specified in clause (2) of this
      Section 2.12(e), the Company will promptly make available to the Trustee a
      reasonable supply of Certificated Securities in definitive, fully registered
      form, without interest coupons. 

     

    (6)  Neither
      Agent Members nor any other Persons on whose behalf Agent Members may act shall
      have any rights under this Indenture with respect to any Global Security
      registered in the name of the Depositary or any nominee thereof, or under any
      such Global Security, and the Depositary or such nominee, as the case may be,
      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. Notwithstanding the foregoing, nothing herein shall prevent
      the Company, the Trustee or any agent of the Company or the Trustee from giving
      effect to any written certification, proxy or other authorization furnished
      by
      the Depositary or such nominee, as the case may be, or impair, as between the
      Depositary, its Agent Members and any other Person on whose behalf an Agent
      Member may act, the operation of customary practices of such Persons governing
      the exercise of the rights of a holder of any Security. 

     

    (7)  At
      such
      time as all interests in a Global Security have been converted, canceled or
      exchanged for Securities in certificated form, such Global Security shall,
      upon
      receipt thereof, be cancelled by the Trustee in accordance with standing
      procedures and instructions existing between the Depositary and the Securities
      Custodian, subject to Section 2.11 of this Indenture. At any time prior to
      such
      cancellation, if any interest in a 

     

    
      
        
        

      

      
        19

        
          

        

      

      
        
        

      

    

    Global
      Security is converted, canceled or exchanged for Securities in certificated
      form, the principal amount of such Global Security shall, in accordance with
      the
      standing procedures and instructions existing between the Depositary and the
      Securities Custodian, be appropriately reduced, and an endorsement shall be
      made
      on such Global Security, by the Trustee or the Securities Custodian, at the
      direction of the Trustee, to reflect such reduction. 

     

    (f)  Until
      the
      expiration of the holding period applicable to sales thereof under Rule 144(k)
      under the Securities Act (or any successor provision thereto), any stock
      certificate representing Common Stock issued upon conversion of any Security
      shall bear a legend in substantially the following form, unless such Common
      Stock has been sold pursuant to a registration statement that has been declared
      effective under the Securities Act (and which continues to be effective at
      the
      time of such transfer) or transferred in compliance with Rule 144 under the
      Securities Act (or any successor provision thereto), or such Common Stock has
      been issued upon conversion of Securities that have been transferred pursuant
      to
      a registration statement that has been declared effective under the Securities
      Act or pursuant to Rule 144 under the Securities Act (or any successor provision
      thereto), or unless otherwise agreed by the Company in writing with written
      notice thereof to the transfer agent:

     

    THE
      COMMON STOCK EVIDENCED HEREBY HAS NOT BEEN REGISTERED UNDER THE SECURITIES
      ACT
      OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR ANY STATE SECURITIES LAWS, AND,
      ACCORDINGLY, MAY NOT BE REOFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED,
      ENCUMBERED OR OTHERWISE DISPOSED OF IN THE ABSENCE OF SUCH REGISTRATION OR
      UNLESS SUCH TRANSACTION IS EXEMPT FROM, OR NOT SUBJECT TO, REGISTRATION UNDER
      THE SECURITIES ACT.

     

    BY
      ITS
      ACQUISITION HEREOF, THE HOLDER AGREES TO OFFER, SELL OR OTHERWISE TRANSFER
      THE
      COMMON STOCK EVIDENCED HEREBY PRIOR TO THE DATE THAT IS TWO YEARS AFTER THE
      LATER OF THE ORIGINAL ISSUE DATE HEREOF AND THE LAST DATE ON WHICH CHATTEM
      INC.
      (THE “COMPANY”) OR ANY AFFILIATE OF THE COMPANY WAS THE OWNER OF THE COMMON
      STOCK EVIDENCED HEREBY (OR ANY PREDECESSOR OF THE COMMON STOCK EVIDENCED HEREBY)
      (THE “RESALE RESTRICTION TERMINATION DATE”) ONLY (A) TO THE COMPANY OR ANY
      SUBSIDIARY THEREOF, (B) PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BEEN
      DECLARED EFFECTIVE UNDER THE SECURITIES ACT, OR (C) PURSUANT TO ANY OTHER
      AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT,
      SUBJECT TO THE COMPANY’S AND THE TRANSFER AGENT’S RIGHT PRIOR TO ANY SUCH OFFER,
      SALE OR TRANSFER PURSUANT TO CLAUSE (C) PRIOR TO THE RESALE RESTRICTION
      TERMINATION DATE TO REQUIRE THE DELIVERY OF AN OPINION OF COUNSEL,
      CERTIFICATIONS AND/OR OTHER INFORMATION SATISFACTORY TO EACH OF THEM, AND IN
      EACH OF THE FOREGOING CASES, TO REQUIRE THAT A CERTIFICATE OF TRANSFER IN THE
      FORM APPEARING ON THE OTHER SIDE OF THIS CERTIFICATE IS COMPLETED AND DELIVERED
      BY THE TRANSFEROR TO THE TRANSFER AGENT. THIS LEGEND WILL BE REMOVED UPON THE
      REQUEST OF THE HOLDER AFTER THE RESALE RESTRICTION TERMINATION
      DATE.

    Any
      such
      Common Stock as to which such restrictions on transfer shall have expired in
      accordance with their terms or as to which the conditions for removal of the
      foregoing legend set forth therein have been satisfied may, upon surrender
      of
      the certificates representing such shares of Common Stock for exchange in
      accordance with the procedures of the transfer agent for the Common Stock,
      be
      exchanged for a new certificate or certificates for a like number of shares
      of
      Common Stock, which shall not bear the restrictive legend required by this
      section.

     

    Section
      2.13.  CUSIP
      Numbers.

     

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

    Section
      3.01.  Purchase
      at Holders’ Option upon a Fundamental Change.

     

    (a)  If
      a
      Fundamental Change occurs prior to the Final Maturity Date, each Holder of
      a
      Security shall have the right, at the option of the Holder, to require the
      Company to repurchase for cash all or any portion of the Securities of such
      Holder equal to $1,000 principal amount (or an integral multiple thereof) at
      the
      Fundamental Change Purchase Price, on the date (the “Fundamental Change Purchase
      Date”) specified by the Company pursuant to subsection 3.01(b) that is not less
      than 30 days nor more than 45 days after the Fundamental Change Effective
      Date.

     

    (b)  As
      promptly as practicable following the date when the Company publicly announces
      a
      Fundamental Change but in no event less than 10 Trading Days prior to the
      anticipated Fundamental Change Effective Date, the Company shall mail a written
      notice of the Fundamental Change and of the resulting repurchase right to the
      Trustee, Paying Agent and to each Holder (and to beneficial owners as required
      by applicable law) (the “Fundamental Change Company Notice”). The Fundamental
      Change Company Notice shall include the form of a Fundamental Change Purchase
      Notice to be completed by the Holder and shall state:

     

    (1)  the
      events causing such Fundamental Change; 

     

    (2)  the
      date
      (or expected date) of such Fundamental Change;

      law. 

     

    
      
        
        

      

      
        22

        
          

        

      

      
        
        

      

    

    (1)  The
      Fundamental Change Purchase Notice shall state: (A) the certificate number
      (if
      such Security is held other than in global form) of the Security which the
      Holder will deliver to be purchased (or, if the Security is held in global
      form,
      any other items required to comply with the Applicable Procedures), (B) the
      portion of the principal amount of the Security which the Holder will deliver
      to
      be purchased, which portion must be $1,000 or an integral multiple of $1,000
      and
      (C) that such Security shall be purchased as of the Fundamental Change Purchase
      Date pursuant to the terms and conditions specified in the Securities and in
      this Indenture. 

     

    (2)  The
      delivery of a Security for which a Fundamental Change Purchase Notice has been
      timely delivered to any Paying Agent and not validly withdrawn prior to, on
      or
      after the Fundamental Change Purchase Notice (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 therefor.

     

    (3)  The
      Company shall only be obliged to purchase, pursuant to this Section 3.01, 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
      purchase of all of a Security also apply to the purchase of such portion of

      Security).

     

    (4)  Notwithstanding
      anything herein to the contrary, any Holder delivering to a Paying Agent the
      Fundamental Change Purchase Notice contemplated by this Section 3.01(c) shall
      have the right to withdraw such Fundamental Change Purchase Notice in whole
      or
      in a portion thereof that is a principal amount of $1,000 or in an integral
      multiple thereof at any time prior to the close of business on the Business
      Day
      prior to the Fundamental Change Purchase Date by delivery of a written notice
      of
      withdrawal to the Paying Agent in accordance with Section 3.02. 

     

    (5)  A
      Paying
      Agent shall promptly notify the Company of the receipt by it of any Fundamental
      Change Purchase Notice or written withdrawal thereof. 

     

    (6)  Anything
      herein to the contrary notwithstanding, 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 as in effect from time to time.

     

    Section
      3.02.  Effect
      of Fundamental Change Purchase Notice.

     

    (a)  Upon
      receipt by any Paying Agent of a properly completed Fundamental Change Purchase
      Notice from a Holder, the Holder of the Security in respect of which such
      Fundamental Change Purchase Notice was given shall (unless such Fundamental
      Change Purchase Notice is withdrawn as specified in Section 3.02(b)) thereafter
      be entitled to receive the Fundamental Change Purchase Price with respect to
      such Security, subject to the occurrence of an absence of an Event of Default,
      or a continuation thereof (other than a Default in the payment of the
      Fundamental Change Purchase Price). Such Fundamental Change Purchase Price
      shall
      be paid to such Holder promptly following the later of (1) the Fundamental
      Change Purchase Date (provided that the conditions in Section 3.01 have been
      satisfied) and (2) the time of delivery of 

     

    
      
        
        

      

      
        23

        
          

        

      

      
        
        

      

    

    such
      Security to a Paying Agent by the Holder thereof in the manner required by
      Section 3.01(c). Securities in respect of which a Fundamental Change Purchase
      Notice has been given by the Holder thereof may not be converted into shares
      of
      Common Stock pursuant to Article 4 on or after the date of the delivery of
      such
      Fundamental Change Purchase Notice unless such Fundamental Change Purchase
      Notice has first been validly withdrawn in accordance with Section 3.02(b)
      with
      respect to the Securities to be converted. 

     

    (b)  A
      Fundamental Change Purchase Notice may be withdrawn by means of a written notice
      (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) of withdrawal delivered by the Holder to a Paying Agent
      at any time prior to the close of business on the Business Day immediately
      prior
      to the Fundamental Change Purchase Date, specifying (1) if certificated
      Securities have been issued, the certificate number of the Security being
      withdrawn in whole or in withdrawable part (or if the Securities are not
      certificated, such written notice must comply with the Applicable Procedures),
      (2) the principal amount of the Security or portion thereof (which must be
      a
      principal amount of $1,000 or an integral multiple of $1,000 in excess thereof)
      with respect to which such notice of withdrawal is being submitted, and (3)
      the
      portion of the principal amount of the Security that will remain subject to
      the
      Fundamental Change Purchase Notice, which portion must be a principal amount
      of
      $1,000 or an integral multiple thereof. 

     

    Section
      3.03.  Deposit
      of Fundamental Change Purchase Price.

     

    (a)  On
      or
      before 10:00 a.m., New York City time, on the applicable Fundamental Change
      Purchase Date, the Company shall deposit with the Trustee or with a 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 of
      money (in immediately available funds), sufficient to pay the aggregate
      Fundamental Change Purchase Price of all the Securities or portions thereof
      that
      are to be purchased as of such Fundamental Change Purchase Date. 

     

    (b)  If
      a
      Paying Agent or the Trustee holds, in accordance with the terms hereof, money
      sufficient to pay the Fundamental Change Purchase Price of any Security for
      which a Fundamental Change Purchase Notice has been tendered and not withdrawn
      in accordance with this Indenture then, on immediately after the applicable
      Fundamental Change Purchase Date, such Security will cease to be outstanding,
      whether or not the Security is delivered to the Paying Agent or the Trustee,
      and
      interest and Additional Interest, if any, shall cease to accrue, and the rights
      of the Holder in respect of the Security shall terminate (other than the right
      to receive the Fundamental Change Purchase Price as aforesaid). The Company
      shall publicly announce the principal amount of Securities repurchased on or
      as
      soon as practicable after the Fundamental Change Purchase Date. 

     

    (c)  The
      Paying Agent will promptly return to the respective Holders thereof any
      Securities with respect to which a Fundamental Change Purchase Notice has been
      withdrawn in compliance with this Indenture. 

     

    
      
        
        

      

      
        24

        
          

        

      

      
        
        

      

    

    (d)  If
      a
      Fundamental Change Purchase Date falls after a Regular Record Date and on or
      before the related Interest Payment Date, then interest on the Securities
      payable on such Interest Payment Date will be payable to the Holders in whose
      names the Securities are registered at the close of business on such Regular
      Record Date.

     

    Section
      3.04.  Repayment
      to The Company.

     

    To
      the
      extent that the aggregate amount of cash deposited by the Company pursuant
      to
      Section 3.03 exceeds the aggregate Fundamental Change Purchase Price of the
      Securities or portions thereof that the Company is obligated to purchase, then
      promptly after the Fundamental Change Purchase Date the Trustee or a Paying
      Agent, as the case may be, shall return any such excess cash to the
      Company.

     

    Section
      3.05.  Securities
      Purchased in Part.

     

    Any
      Security that is to be purchased only in part shall be surrendered at the office
      of a Paying Agent, and promptly after the Fundamental Change Purchase Date,
      the
      Company shall execute and the Trustee shall authenticate and deliver to the
      Holder of such Security, without service charge, a new Security or Securities,
      of such authorized denomination or denominations as may be requested by such
      Holder (which must be equal to $1,000 principal amount or any integral thereof),
      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
      3.06.  Compliance
      with Securities Laws upon Purchase of Securities.

     

    In
      connection with any offer to purchase of Securities under Section 3.01, the
      Company shall (a) comply with Rule 13e-4 and Rule 14e-1 (or any successor to
      either such Rule), and any other tender offer rules, if applicable, under the
      Exchange Act, (b) file the related Schedule TO (or any successor or similar
      schedule, form or report) if required under the Exchange Act, and (c) otherwise
      comply with all federal and state securities laws in connection with such offer
      to purchase or purchase of Securities, all so as to permit the rights of the
      Holders and obligations of the Company under Sections 3.01 through 3.04 to
      be
      exercised in the time and in the manner specified therein. To the extent that
      compliance with any such laws, rules and regulations would result in a conflict
      with any of the terms hereof, this Indenture is hereby modified to the extent
      required for the Company to comply with such laws, rules and
      regulations.

     

    Section
      3.07.  Purchase
      of Securities in Open Market.

     

    The
      Company (a) on or prior to the date that is two years from the latest issuance
      of any Securities and in accordance with Section 2.11, shall surrender any
      Security purchased by the Company pursuant to this Article 3 to the Trustee
      for
      cancellation, and (b) after such date and in accordance with Section 2.11,
      may
      surrender such Security to the Trustee for cancellation. Any securities
      surrendered to the Trustee for cancellation may not be reissued or resold by
      the
      Company and will be canceled promptly in accordance with Section 2.11. The
      Company may repurchase Securities in the open market, by tender at any price
      or
      by negotiated transactions and such Securities may be reissued or resold, to
      the
      extent permitted by applicable law, or may be surrendered to the Trustee for
      cancellation.

    ARTICLE
      4

    CONVERSION

     

    Section
      4.01.  Conversion
      Privilege and Conversion Rate.

     

    (a)  Subject
      to the obligation and the right of the Company to pay some or all of the
      conversion consideration in cash in accordance with Section 4.13, and upon
      compliance with the provisions of this Article 4, at the option of the Holder
      thereof, any Security or portion thereof that is an integral multiple of $1,000
      principal amount may be converted into fully paid and nonassessable shares
      (calculated as to each conversion to the nearest 1/100th of a share) of Common
      Stock prior to the close of business on the Business Day immediately preceding
      the Final Maturity Date or such earlier date set forth in this Article 4, unless
      previously purchased by the Company at the Holder’s option upon the occurrence
      of a Fundamental Change, at the Conversion Rate in effect at such time,
      determined as hereinafter provided and subject to the adjustments described
      below, only under the following circumstances:

     

    (1)  during
      any fiscal quarter beginning after February 28, 2007, and only during such
      fiscal quarter, if, as of the last day of the immediately preceding fiscal
      quarter, the Closing Price per share of the Common Stock for at least 20 Trading
      Days in the period of the 30 consecutive Trading Days ending on the last Trading
      Day of such preceding calendar quarter was more than 130% of the Conversion
      Price (the “Conversion Trigger Price”);

     

    (2)  if
      the
      Company distributes to all holders of Common Stock rights (including rights
      under a shareholder rights agreement) or warrants entitling them to purchase,
      for a period expiring within 45 days of the date of issuance, Common Stock
      at
      less than the Current Market Price of the Common Stock on the day of issuance;
      

     

    (3)  if
      the
      Company distributes to all holders of Common Stock, assets, debt securities
      or
      rights to purchase the Company’s securities, which distribution has a per share
      value exceeding 15% of the average of the Closing Prices of the Common Stock
      for
      the five consecutive Trading Days ending on the date immediately preceding
      the
      first public announcement of such distribution; 

     

    (4)  if
      a
      Fundamental Change occurs; 

     

    (5)  at
      any
      time during the one month period beginning on October 15, 2013 and ending
      at the close of business on the Business Day immediately preceding the Final
      Maturity Date; or 

     

    (6)  prior
      to
      October 15, 2013, during any five Business Day period after any five
      consecutive Trading Day period in which the Trading Price per $1,000 principal
      amount of Securities, as determined following a request by a Holder in
      accordance with the procedures described below in Section 4.01(e)(ii), for
      each
      day of that period was less than 97% of the product of the Closing Price of
      the
      Common Stock and the then applicable Conversion Rate.

     

    
      
        
        

      

      
        26

        
          

        

      

      
        
        

      

    

    (b)  In
      the
      case of a distribution contemplated by clauses (2) and (3) of Section 4.01(a),
      the Company shall notify Holders and Trustee at least 20 days prior to the
      ex-dividend date for such distribution (the “Distribution Notice”); provided
      that if the Company distributes rights pursuant to a shareholder rights
      agreement, it will notify the Holders of the Securities on the Business Day
      after the Company is required to give notice generally to its shareholders
      pursuant to such shareholder rights agreement if such date is less than 20
      days
      prior to the date of such distribution. Once the Company has given the
      Distribution Notice, Holders may surrender their Securities for conversion
      at
      any time until the earlier of the close of business on the last Business Day
      preceding the ex-dividend date or the Company’s announcement that such
      distribution will not take place. Notwithstanding the provisions of clauses
      (2)
      and (3) of Section 4.01(a), Holders may not convert the Securities if the
      Holders will be entitled to participate in such distribution on an as converted
      basis. The Company will provide written notice to the Conversion Agent as soon
      as reasonably practicable of any anticipated or actual event or transaction
      that
      will cause or causes the Securities to become convertible pursuant to clauses
      (2) or (3) of Section 4.01(a). 

     

    (c)  [Intentionally
      Omitted] 

     

    (d)  In
      the
      case of a transaction contemplated by clause (4) of section 4.01(a), the Company
      will notify the Holders and Trustee at least 10 Trading Days prior to the
      anticipated Fundamental Change Effective Date of any Fundamental Change. Holders
      may surrender Securities for conversion at any time beginning 10 Trading Days
      before the anticipated Fundamental Change Effective Date of a Fundamental Change
      and until the last Trading Day preceding the Fundamental Change Purchase Date.
      

     

    (e)  (i)
      For each
      fiscal quarter of the Company, beginning with the fiscal quarter ending
      February 28, 2007, the Company will determine, on the first Business Day
      following the last Trading Day of such fiscal quarter, whether the Securities
      are convertible pursuant to clause (1) of Section 4.01(a), and, if so, will
      notify the Trustee in writing. Upon request of the Conversion Agent, the Company
      shall provide, or cause to be provided to, the Conversion Agent the Closing
      Price per share of Common Stock for the 30 consecutive Trading Days ending
      on
      the last Trading Day of the preceding fiscal quarter. 

     

    (ii)  The
      Company shall have no obligation to determine the Trading Price of the
      Securities and whether the Securities are convertible pursuant to clause (6)
      of
      Section 4.01(a) unless a Holder of Securities provides the Company with
      reasonable evidence that the Trading Price per $1,000 principal amount of
      Securities would be less than 97% of the product of the Closing Price of the
      Common Stock and the Conversion Rate per $1,000 principal amount of Securities.
      At such time, the Company shall 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 the Securities is greater than
      97%
      of the product of the Closing Price of the Common Stock and the Conversion
      Rate
      per $1,000 principal amount of the Securities. 

     

    (f)  The
      conversion rights pursuant to this Article 4 shall commence on the initial
      issuance date of the Securities and expire at the close of business on the
      Business Day immediately preceding the Final Maturity Date, but shall be
      exercisable only during the time 

     

    
      
        
        

      

      
        27

        
          

        

      

      
        
        

      

    

    periods
      specified with respect to each circumstance pursuant to which the Securities
      become convertible, subject, in the case of conversion of any Global Security,
      to any Applicable Procedures. If a Security is convertible as a result of a
      Fundamental Change, such conversion right shall commence and terminate as set
      forth in Section 4.01(d). Securities in respect of which a Fundamental Change
      Purchase Notice has been delivered may not be surrendered for conversion
      pursuant to this Article 4 prior to a valid withdrawal of such Fundamental
      Change Notice in accordance with the provisions of Article 3.

     

    (g)  Provisions
      of this Indenture that apply to conversion of all of a Security also apply
      to
      conversion of a portion of a Security.

     

    (h)  A
      Holder
      of Securities is not entitled to any rights of a holder of Common Stock until
      such Holder has converted its Securities into Common Stock, and only to the
      extent such Securities are deemed to have been converted into Common Stock
      pursuant to this Article 4.

     

    (i)  The
      Conversion Rate shall be adjusted in certain instances as provided in Section
      4.01(j) and Section 4.06.

     

    (j)  If
      a
      Fundamental Change occurs as a result of a Termination of Trading or as a result
      of the occurrence of one of the events specified in clause (i), (ii), (iii)
      or
      (v) of the definition of the term Change in Control, the Company shall pay,
      to
      the extent set forth in this Section 4.01(j), a make-whole premium to a Holder
      who converts its Securities in connection with any such transaction by
      increasing the Conversion Rate applicable to such Securities. A conversion
      of
      Securities will be deemed for the purposes of this Section 4.01(j) to be “in
      connection with” a Fundamental Change if the Conversion Notice set forth in the
      form of Security attached as Exhibit A is received by the Conversion Agent
      on or
      subsequent to the date 10 Trading Days prior to the date announced by the
      Company as the anticipated Fundamental Change Effective Date but before the
      close of business on the Business Day immediately preceding the related
      Fundamental Change Purchase Date. Any increase in the applicable Conversion
      Rate
      shall be determined by reference to the table below and shall be based on the
      date on which the Fundamental Change Effective Date occurs and the price paid,
      or deemed to be paid, per share of Common Stock in the transaction constituting
      the Fundamental Change (the “Stock Price”). If holders of Common Stock receive
      only cash in the Fundamental Change, the Stock Price shall be the cash amount
      paid per share of Common Stock. In all other cases, the Stock Price shall be
      the
      average of the Closing Prices of the Common Stock for each of the 10 Trading
      Days immediately prior to but not including the Fundamental Change Effective
      Date.

     

    The
      following table sets forth the amount, if any, by which the applicable
      Conversion Rate shall increase for each Stock Price and Fundamental Change
      Effective Date set forth below.

    *Original
      issue date of the notes.

     

    The
      actual Stock Price and Fundamental Change Effective Date may not be set forth
      in
      the table, in which case:

     

    (i)  if
      the
      actual Stock Price on the Fundamental Change Effective Date is between two
      Stock
      Prices in the table or the actual Fundamental Change Effective Date is between
      two Fundamental Change Effective Dates in the table, the amount of the
      Conversion Rate adjustment shall be determined by a straight-line interpolation
      between the adjustment amounts set forth for the two Stock Prices and the two
      Fundamental Change Effective Dates set forth in the table based on a 365-day
      year, as applicable;

     

    (ii)  if
      the
      Stock Price on the Effective date exceeds $200.00 per share, subject to
      adjustment as described below, no adjustment to the applicable conversion rate
      will be made; and

     

    (iii)  if
      the
      stock price
      on the
      effective date is less than $46.76 per share, subject to adjustment as described
      below, no adjustment to the applicable conversion rate will be
      made.

     

    The
      Stock
      Prices set forth in the first column of the table above will be adjusted as
      of
      any date on which the Conversion Rate of the Securities is adjusted in
      accordance with Section 4.06. The adjusted Stock Prices shall equal the Stock
      Prices applicable immediately prior to such adjustment multiplied by a fraction,
      the numerator of which shall be the Conversion Rate immediately prior to the
      adjustment giving rise to the Stock Price adjustment and the denominator of
      which shall be the Conversion Rate as so adjusted. The Conversion Rate
      adjustment amounts set forth in the table above shall be adjusted in the same
      manner as the Conversion Rate as set forth in Section 4.06.

     

    Notwithstanding
      the foregoing paragraph, in no event will the Conversion Rate exceed 21.3858
      per
      $1,000 principal amount of Securities, subject to adjustment in the manner
      set
      forth in clauses (1) through (4) of Section 4.06(a) hereof.

     

    (k)  Except
      as
      set forth in Section 4.02(c), by delivering the amount of cash and/or the number
      of shares of Common Stock issuable on conversion to the Trustee, the Company
      will be

    deemed
      to
      have satisfied its obligation to pay the principal amount of the Securities
      so
      converted and its obligation to pay accrued and unpaid interest, and Additional
      Interest if any, attributable to the period from the most recent Interest
      Payment Date through the Conversion Date (which amount will be deemed paid
      in
      full rather than cancelled, extinguished or forfeited).

     

    (l)  Notwithstanding
      anything else contained herein, the Securities shall not become subject to
      conversion by reason of a merger, consolidation, or other transaction effected
      with the Company’s direct or indirect Subsidiaries for the sole purpose of
      changing the Company’s state of incorporation to any other state within the
      United States or the District of Columbia.

     

    Section
      4.02.  Conversion
      Procedure.

     

    (a)  To
      convert a Security, the Holder must (1) complete and manually sign the
      Conversion Notice on the reverse of the Security and deliver such notice to
      the
      Conversion Agent, (2) surrender the Security to the Conversion Agent, (3)
      furnish appropriate endorsements and transfer documents if required by the
      Conversion Agent, and (4) pay all transfer or similar taxes, if required
      pursuant to Section 4.04. The date on which the Holder satisfies all of those
      requirements is the “Conversion Date.” Upon the conversion of a Security, the
      Company shall settle its conversion obligation in the manner set forth in
      Section 4.13.

     

    (b)  The
      person in whose name the shares of Common Stock, if any, that are issued upon
      conversion shall be deemed to be a holder of record of such shares of Common
      Stock on the date on which such shares, if any, are delivered to the Holder
      in
      accordance with the provisions of Section 4.13. Except as set forth in this
      Indenture, no payment or adjustment will be made for dividends or distributions
      declared or made on shares of Common Stock issued upon conversion of a Security
      prior to the issuance of such shares.

     

    (c)  Holders
      of Securities surrendered for conversion (in whole or in part) during the period
      from the close of business on any Regular Record Date to the opening of business
      on the next succeeding Interest Payment Date will receive the semi-annual
      interest payable on such Securities on the corresponding Interest Payment Date
      notwithstanding the conversion. Except as otherwise provided in this Section
      4.02(c), no payment or adjustment will be made for accrued interest on a
      converted Security.

     

    (d)  Subject
      to Section 4.02(c), nothing in this Section shall affect the right of a Holder
      in whose name any Security is registered at the close of business on a Regular
      Record Date to receive the interest payable on such Security on the related
      Interest Payment Date in accordance with the terms of this Indenture, the
      Securities and the Registration Rights Agreement. If a Holder converts more
      than
      one Security at the same time, the amount of cash to be paid and the number
      of
      shares of Common Stock issuable upon the conversion, if any (and the amount
      of
      any cash in lieu of fractional shares pursuant to Section 4.03), shall be based
      on the aggregate principal amount of all Securities so converted. 

     

    (e)  In
      the
      case of any Security which is converted in part only, upon such conversion
      the
      Company shall execute and the Trustee shall authenticate and deliver to the
      Holder thereof, without service charge, a new Security or Securities of
      authorized denominations in an aggregate principal amount equal to, and in
      exchange for, the unconverted portion of the principal amount 

     

    
      
        
        

      

      
        30

        
          

        

      

      
        
        

      

    

    of
      such
      Security. A Security may be converted in part, but only if the principal amount
      of such part is an integral multiple of $1,000 and the principal amount of
      such
      Security to remain outstanding after such conversion is equal to $1,000 or
      any
      integral multiple of $1,000 in excess thereof. 

     

    (f)  Upon
      the
      Company’s determination that a Holder is or will be entitled to convert its
      Securities pursuant to this Article 4, the Company will promptly after making
      such determination issue a press release and use reasonable efforts to post
      such
      information on the Company’s website or otherwise publicly disclose such
      information.

     

    Section
      4.03.  Fractional
      Shares.

     

    The
      Company will not issue fractional shares of Common Stock upon conversion of
      Securities. If more than one Security shall be surrendered for conversion at
      one
      time by the same Holder, the number of full shares that 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. In lieu of any fractional shares, the Company will pay an amount
      in
      cash for the current market value of the fractional shares. The current market
      value of a fractional share shall be determined (calculated to the nearest
      1/100th of a share) by multiplying the arithmetic average of the Volume Weighted
      Average Price of the Common Stock for each of the twenty consecutive Trading
      Days of the Conversion Reference Period by such fractional share and rounding
      the product to the nearest whole cent.

     

    Section
      4.04.  Taxes
      on Conversion.
      If a
      Holder converts a Security, the Company shall pay any transfer, stamp or similar
      taxes or duties related to the issue or delivery of shares of Common Stock,
      if
      any, upon such conversion. The Company shall also pay any such tax with respect
      to cash received in lieu of fractional shares. The Holder shall pay any such
      tax
      which is due because the Holder requests the shares to be issued in a name
      other
      than the Holder’s name. The Conversion Agent may refuse to deliver the
      certificate representing the 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 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
      4.05.  Company
      to Provide Stock.

     

    (a)  The
      Company shall, prior to issuance of any Securities hereunder, and from time
      to
      time as may be necessary, reserve, out of its authorized but unissued Common
      Stock, a sufficient number of shares of Common Stock to permit the conversion
      of
      all outstanding Securities into shares of Common Stock. 

     

    (b)  All
      shares of Common Stock delivered upon conversion of the Securities shall be
      duly
      authorized, validly issued, fully paid and nonassessable and shall be free
      from
      preemptive or similar rights of any securityholder of the Company and free
      of
      any lien or adverse claim as the result of any action by the Company.

     

    
      
        
        

      

      
        31

        
          

        

      

      
        
        

      

    

    (c)  The
      Company will endeavor promptly to comply with all federal and state securities
      laws regulating the offer and delivery of shares of Common Stock upon conversion
      of Securities.

     

    Section
      4.06.  Adjustment
      of Conversion Rate.

     

    (a)  The
      Conversion Rate shall be adjusted from time to time by the Company as follows:
      

     

    (1)  If
      the
      Company shall pay a dividend or make a distribution to all holders of
      outstanding Common Stock in shares of Common Stock, the Conversion Rate in
      effect immediately prior to the record date for the determination of
      shareholders entitled to receive such dividend or other distribution shall
      be
      increased so that the same shall equal the rate determined by multiplying the
      Conversion Rate in effect immediately prior to such record date by a fraction
      of
      which the numerator shall be the sum of the number of shares of Common Stock
      outstanding at the close of business on such record date plus the total number
      of shares of Common Stock constituting such dividend or other distribution
      and
      of which the denominator shall be the number of shares of Common Stock
      outstanding at the close of business on such record date. Such adjustment shall
      be made successively whenever any such dividend or distribution is made and
      shall become effective immediately after such record date. For the purpose
      of
      this clause (1), the number of shares of Common Stock at any time outstanding
      shall not include shares held in the treasury of the Company (to the extent
      any
      shares may be held in the treasury of the Company). The Company will not pay
      any
      dividend or make any distribution on Common Stock held in the treasury of the
      Company (to the extent any shares may be held in the treasury of the Company).
      If any dividend or distribution of the type described in this clause is declared
      but not so paid or made, the Conversion Rate shall again be adjusted to the
      Conversion Rate that would then be in effect if such dividend or distribution
      had not been declared. 

     

    (2)  If
      the
      Company shall subdivide its outstanding Common Stock into a greater number
      of
      shares, or combine its outstanding Common Stock into a smaller number of shares,
      the Conversion Rate in effect immediately prior to the day upon which such
      subdivision or combination becomes effective shall be, in the case of a
      subdivision of Common Stock, proportionately increased and, in the case of
      a
      combination of Common Stock, proportionately reduced. Such adjustment shall
      be
      made successively whenever any such subdivision or combination of the Common
      Stock occurs and shall become effective immediately after the date upon which
      such subdivision or combination becomes effective. 

     

    (3)  If
      the
      Company shall issue rights or warrants to all holders of its outstanding Common
      Stock entitling them for a period expiring within 45 days after such issuance
      to
      subscribe for or purchase shares of Common Stock (or securities convertible
      into
      Common Stock) at a price per share (or having a conversion price per share)
      less
      than the Current Market Price per share of Common Stock (as determined in
      accordance with clause (9) of this Section 4.06(a)) on the record date for
      the
      determination of shareholders entitled to receive such rights or warrants,
      the
      Conversion Rate in effect immediately prior thereto shall be adjusted so that
      the same shall equal the rate determined by multiplying the Conversion Rate
      in
      effect 

     

    
      
        
        

      

      
        32

        
          

        

      

      
        
        

      

    

    immediately
      prior to such record date by a fraction of which the numerator shall be the
      number of shares of Common Stock outstanding at the close of business on such
      record date plus the number of additional shares of Common Stock that such
      rights or warrants entitle holders thereof to subscribe for or purchase (or
      into
      which such convertible securities are convertible) and of which the denominator
      shall be the number of shares of Common Stock outstanding at the close of
      business on such record date plus the number of shares which the aggregate
      offering price of the total number of shares of Common Stock so offered for
      subscription or purchase (or the aggregate conversion price of the convertible
      securities so offered for subscription or purchase, which shall be determined
      by
      multiplying the number of shares of Common Stock issuable upon conversion of
      such convertible securities by the conversion price per share of Common Stock
      pursuant to the terms of such convertible securities) would purchase at the
      Current Market Price per share of Common Stock on such record date. Such
      adjustment shall be made successively whenever any such rights or warrants
      are
      issued, and shall become effective immediately after such record date. To the
      extent that shares of Common Stock (or securities convertible into Common Stock)
      are not delivered after the expiration of such rights or warrants, the
      Conversion Rate shall be readjusted to the Conversion Rate that would then
      be in
      effect had the adjustments made upon the issuance of such rights or warrants
      been made on the basis of delivery of only the number of shares of Common Stock
      (or securities convertible into Common Stock) actually delivered. If such rights
      or warrants are not so issued, the Conversion Rate shall again be adjusted
      to be
      the Conversion Rate that would then be in effect if the record date for the
      determination of shareholders entitled to receive such rights or warrants had
      not been fixed. In determining whether any rights or warrants entitle the
      shareholders to subscribe for or purchase shares of Common Stock at a price
      less
      than the Current Market Price per share of Common Stock and in determining
      the
      aggregate offering price of the total number of shares of Common Stock so
      offered, there shall be taken into account any consideration received by the
      Company for such rights or warrants and any amount payable on exercise or
      conversion thereof, the value of such consideration, if other than cash, to
      be
      determined by the Board of Directors. 

     

    (4)  If
      the
      Company shall make a dividend or other distribution to all holders of its Common
      Stock of Capital Stock, other than Common Stock, or evidences of indebtedness
      or
      other assets of the Company (excluding (x) any issuance of rights or warrants
      to
      which the provisions of Section 4.06(a)(3) shall apply, (y) dividends or
      distributions in connection with a reclassification, change, consolidation,
      merger, combination, liquidation, dissolution, winding up, sale or conveyance
      resulting in a change in the conversion consideration, or pursuant to any
      shareholder rights plan or (z) any dividend or distribution paid exclusively
      in
      cash to which the provisions of Section 4.06(a)(6) shall apply) (the
“Distributed Securities”), then in each such case (unless the Company
      distributes such Distributed Securities for distribution to the Holders of
      Securities on such dividend or distribution date as if each Holder had converted
      such Security into a number of shares of Common Stock equal to the then
      applicable Conversion Rate immediately prior to the record date with respect
      to
      such distribution) the Conversion Rate in effect immediately prior to the record
      date fixed for the determination of shareholders entitled to receive such
      dividend or distribution shall be 

    
      
        
        

      

      
        33

        
          

        

      

      
        
        

      

    

    adjusted
      so that the same shall equal the rate determined by multiplying the Conversion
      Rate in effect immediately prior to such record date by a fraction of which
      the
      numerator shall be the Current Market Price per share of the Common Stock on
      such record date and of which the denominator shall be Current Market Price
      per
      share on such record date less the fair market value (as determined in good
      faith by the Board of Directors, whose determination shall be conclusive
      evidence of such fair market value and which shall be evidenced by an Officers’
Certificate delivered to the Trustee) on such record date of the portion of
      the
      Distributed Securities so distributed applicable to one share of Common Stock
      (determined on the basis of the number of shares of Common Stock outstanding
      at
      the close of business on such record date). Such adjustment shall be made
      successively whenever any such distribution is made and shall become effective
      immediately after the record date for the determination of shareholders entitled
      to receive such distribution. In the event that 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.

     

    If
      the
      fair market value (as so determined) of the portion of the Distributed
      Securities so distributed applicable to one share of Common Stock is equal
      to or
      greater than the Current Market Price per share of the Common Stock on such
      record date, in lieu of the foregoing adjustment, adequate provision shall
      be
      made so that each holder of a Security shall have the right to receive upon
      conversion the amount of Distributed Securities so distributed that such Holder
      would have received had such Holder converted each Security on such record
      date
      into a number of shares of Common Stock equal to the Conversion Rate. If the
      Board of Directors determines the fair market value of any distribution for
      purposes of this Section 4.06(a)(4) by reference to the actual or when issued
      trading market for any securities, it must in doing so consider the prices
      in
      such market over the same period used in computing the Current Market Price
      of
      the Common Stock.

     

    Notwithstanding
      the foregoing, if the securities distributed by the Company to all holders
      of
      its Common Stock consist of Capital Stock of, or similar equity interests in,
      a
      Subsidiary or other business unit of the Company (the “Spinoff Securities”), the
      Conversion Rate shall be adjusted so that the same shall be equal to the rate
      determined by multiplying the Conversion Rate in effect on the record date
      fixed
      for the determination of shareholders entitled to receive such distribution
      by a
      fraction, the numerator of which shall be the sum of (A) the average Closing
      Price of one share of Common Stock over the ten consecutive Trading Day period
      (the “Spinoff Valuation Period”) commencing on and including the fifth Trading
      Day after the date on which ex-dividend trading commences for such distribution
      on the Nasdaq Global Market or such other U.S. national or regional exchange
      or
      market on which the Common Stock is then listed or quoted and (B) the average
      of
      the Closing Prices over the Spinoff Valuation Period of the Spinoff Securities
      multiplied by the number of Spinoff Securities distributed in respect of one
      share of Common Stock and the denominator of which shall be the average Closing
      Price of one share of Common Stock over the Spinoff Valuation Period, such
      adjustment to become effective immediately prior to the opening of business
      on
      the fifteenth Trading Day after the date on which ex-dividend trading commences;
      provided, however, that the Company may in lieu of the foregoing adjustment
      elect to 

     

    
      
        
        

      

      
        34

        
          

        

      

      
        
        

      

    

    make
      an
      equivalent distribution to the Holders of the Securities or make adequate
      provision so that each Holder of Securities shall have the right to receive
      upon
      conversion thereof the amount of such Spinoff Securities that such Holder of
      Securities would have received if such Securities had been converted on the
      record date with respect to such distribution. 

     

    (5)  With
      respect to any rights or warrants (the “Rights”) that may be issued or
      distributed pursuant to any existing rights plan of the Company or any rights
      plans implemented by the Company after the date of this Indenture (a “Rights
      Plan”), the Holders of Securities will receive, with respect to any shares of
      Common Stock issued upon conversion, the Rights described therein (whether
      or
      not the Rights have separated from the Common Stock at the time of conversion),
      subject to the limitations set forth in and in accordance with any such Rights
      Plan; provided that if at the time of conversion the Rights have separated
      from
      the shares of Common Stock in accordance with the provisions of the Rights
      Plan
      so that Holders would not be entitled to receive any rights in respect of the
      shares of Common Stock, if any, issuable upon conversion of the Securities
      as a
      result of the timing of the Conversion Date, the Conversion Rate will be
      adjusted as if the Company distributed to all holders of Common Stock
      Distributed Securities constituting such rights as provided in the first
      paragraph of clause (4) of this Section 4.06(a), subject to appropriate
      readjustment in the event of the expiration, termination, repurchase or
      redemption of the Rights. Other than as specified in this clause (5) of this
      Section 4.06(a), there will not be any adjustment to the Conversion Rate as
      the
      result of the issuance of any Rights, the distribution of separate certificates
      representing such Rights, the exercise or redemption of such Rights in
      accordance with any Rights Plan or the termination or invalidation of any
      Rights.

     

    (6)  If
      the
      Company shall, by dividend or otherwise, at any time distribute (a “Triggering
      Distribution”) to all holders of its Common Stock a payment consisting
      exclusively of cash (excluding any dividend or distribution in connection with
      the liquidation, dissolution or winding up of the Company, whether voluntary
      or
      involuntary) the Conversion Rate shall be increased so that the same shall
      equal
      the rate determined by multiplying such Conversion Rate in effect immediately
      prior to the close of business on the record date for such Triggering
      Distribution (a “Determination Date”) by a fraction of which the numerator shall
      be such Current Market Price per share of the Common Stock on the Determination
      Date and the denominator of which shall be the Current Market Price per share
      of
      the Common Stock on the Determination Date less the amount of such cash dividend
      or distribution applicable to one share of Common Stock (determined on the
      basis
      of the number of shares of Common Stock outstanding at the close of business
      on
      the Determination Date), such increase to become effective immediately prior
      to
      the opening of business on the day following the record date relating to such
      Triggering Distribution. If the amount of cash dividend or distribution
      applicable to one share of Common Stock is equal to or greater than the Current
      Market Price per share of the Common Stock on the Determination Date, in lieu
      of
      the foregoing adjustment, adequate provision shall be made so that each Holder
      of a Security shall have the right to receive upon conversion the amount of
      cash
      so distributed that such Holder would have received had such Holder converted
      each Security on such Determination Date into a number of shares of Common
      Stock
      equal to the Conversion Rate. In the event that such dividend 

     

    
      
        
        

      

      
        35

        
          

        

      

      
        
        

      

    

    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 divided or
      distribution had not been declared.

     

    (7)  If
      any
      tender offer made by the Company or any of its Subsidiaries for all or any
      portion of Common Stock shall expire, then, if the tender offer shall require
      the payment to shareholders of consideration per share of Common Stock having
      a
      fair market value (determined as provided below) that exceeds the Closing Price
      per share of Common Stock on the Trading Day next succeeding the last date
      (the
“Expiration Date”) tenders could have been made pursuant to such tender offer
      (as it may be amended) (the last time at which such tenders could have been
      made
      on the Expiration Date is hereinafter sometimes called the “Expiration Time”),
      the Conversion Rate shall be increased so that the same shall equal the rate
      determined by multiplying the Conversion Rate in effect immediately prior to
      the
      close of business on the Expiration Date by a fraction of which the numerator
      shall be the sum of (A) the fair market value of the aggregate consideration
      (the fair market value as determined in good faith by the Board of Directors,
      whose determination shall be conclusive evidence of such fair market value
      and
      which shall be evidenced by an Officers’ Certificate delivered to the Trustee)
      payable to shareholders based on the acceptance (up to any maximum specified
      in
      the terms of the tender offer) of all shares validly tendered and not withdrawn
      as of the Expiration Time (the shares deemed so accepted, up to any such
      maximum, being referred to as the “Purchased Shares”) and (B) the product of the
      number of shares of Common Stock outstanding (less any Purchased Shares and
      excluding any shares held in the treasury of the Company) at the Expiration
      Time
      and the Closing Price per share of Common Stock on the Trading Day next
      succeeding the Expiration Date and the denominator of which shall be the product
      of the number of shares of Common Stock outstanding (including Purchased Shares
      but excluding any shares held in the treasury of the Company) at the Expiration
      Time multiplied by the Closing Price per share of the Common Stock on the
      Trading Day next succeeding the Expiration Date, such increase to become
      effective immediately prior to the opening of business on the day following
      the
      Expiration Date. In the event that the Company is obligated to purchase shares
      pursuant to any such tender offer, but the Company is permanently prevented
      by
      applicable law from effecting any or all such purchases or any or all such
      purchases are rescinded, the Conversion Rate shall again be adjusted to be
      the
      Conversion Rate which would have been in effect based upon the number of shares
      actually purchased, if any. If the application of this clause (7) of Section
      4.06(a) to any tender offer would result in a decrease in the Conversion Rate,
      no adjustment shall be made for such tender offer under this clause
      (7).

     

    (8)  For
      purposes of this Section 4.06, the term “tender offer” shall mean and include
      both tender offers and exchange offers, all references to “purchases” of shares
      in tender offers (and all similar references) shall mean and include both the
      purchase of shares in tender offers and the acquisition of shares pursuant
      to
      exchange offers, and all references to “tendered shares” (and all similar
      references) shall mean and include shares tendered in both tender offers and
      exchange offers. 

     

    (9)  For
      purposes of any computation under this Section 4.06, “Current Market Price”
shall mean the average of the daily Closing Prices per share of Common Stock
      for

     

    
      
        
        

      

      
        36

        
          

        

      

      
        
        

      

    

    each
      of
      the ten consecutive Trading Days immediately prior to the date in question;
      provided, however, that if 

     

    (A)  the
“ex”
      date (as hereinafter defined) for any event (other than the issuance or
      distribution requiring such computation) that requires an adjustment to the
      Conversion Rate pursuant to Section 4.06(a) (1), (2), (3), (4), (5), (6) or
      (7)
      occurs during such ten consecutive Trading Days, the Closing Price for each
      Trading Day prior to the “ex” date for such other event shall be adjusted by
      dividing such Closing Price by the same fraction by which the Conversion Rate
      is
      so required to be adjusted as a result of such other event; 

     

    (B)  the
“ex”
      date for any event (other than the issuance or distribution requiring such
      computation) that requires an adjustment to the Conversion Rate pursuant to
      Section 4.06(a) (1), (2), (3), (4), (5), (6) or (7) occurs on or after the
“ex”
date for the issuance or distribution requiring such computation and prior
      to
      the day in question, the Closing Price for each Trading Day on and after the
      “ex” date for such other event shall be adjusted by dividing such Closing Price
      by the reciprocal of the fraction by which the Conversion Rate is so required
      to
      be adjusted as a result of such other event; and

     

    (C)  the
“ex”
      date for the issuance or distribution requiring such computation is prior to
      the
      day in question, after taking into account any adjustment required pursuant
      to
      the immediately preceding clause (A) or (B) of this Section 4.06(a)(9), the
      Closing Price for each Trading Day on or after such “ex” date shall be adjusted
      by adding thereto the amount of any cash and the fair market value (as
      determined in good faith by the Board of Directors in a manner consistent with
      any determination of such value for purposes of Section 4.06(a)(4) or (7),
      whose
      determination shall be conclusive and set forth in a board resolution of the
      Board of Directors) of the evidences of indebtedness, shares of capital stock
      or
      assets being distributed applicable to one share of Common Stock as of the
      close
      of business on the day before such “ex” date.

     

    For
      purposes of any computation under Section 4.06(a)(7), if the “ex” date for any
      event (other than the tender offer that is the subject of the adjustment
      pursuant to Section 4.06(a)(7)) that requires an adjustment to the Conversion
      Rate pursuant to Section 4.06(a)(1), (2), (3), (4), (5) or (6) occurs on the
      date of the Expiration Time for the tender or exchange offer requiring such
      computation or on the Trading Day next following the Expiration Time, the
      Closing Price for each Trading Day on and after the “ex” date for such other
      event shall be adjusted by dividing such Closing Price by the reciprocal of
      the
      fraction by which the Conversion Rate is so required to be adjusted as a result
      of such other event. For purposes of this Section 4.06(a)(9) the term “ex” date,
      when used:

     

    
      
        
        

      

      
        37

        
          

        

      

      
        
        

      

    

    (A)  with
      respect to any issuance or distribution, means the first date on which the
      Common Stock trades regular way on the relevant exchange or in the relevant
      market from which the Closing Price was obtained without the right to receive
      such issuance or distribution; 

     

    (B)  with
      respect to any subdivision or combination of shares of Common Stock, means
      the
      first date on which the Common Stock trades regular way on such exchange or
      in
      such market after the time at which such subdivision or combination becomes
      effective, and 

     

    (C)  with
      respect to any tender or exchange offer, means the first date on which the
      Common Stock trades regular way on such exchange or in such market after the
      Expiration Time of such offer.

     

    Notwithstanding
      the foregoing, whenever successive adjustments to the Conversion Rate are called
      for pursuant to this Section 4.06, such adjustments shall be made to the Current
      Market Price as may be necessary or appropriate to effectuate the intent of
      this
      Section 4.06 and to avoid unjust or inequitable results as determined in good
      faith by the Board of Directors.

     

    (10)  Subject
      to applicable stock exchange rules and listing standards, the Company shall
      be
      permitted 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
      Company’s best interest. Subject to applicable stock exchange rules and listing
      standards, the Company may also increase the Conversion Rate to avoid or
      diminish income tax to Holders of the Common Stock in connection with a dividend
      or distribution of Common Stock or similar event.

     

    (b)  In
      any
      case in which this Section 4.06 shall require that an adjustment be made
      following a record date, a Determination Date or Expiration Date, as the case
      may be, established for the purposes specified in this Section 4.06, 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 4.08)
      issuing to the Holder of any Security converted after such record date,
      Determination Date or Expiration Date the shares of Common Stock and other
      Capital Stock of the Company issuable upon such conversion over and above the
      shares of Common Stock and other Capital Stock of the Company (or other cash,
      property or securities, as applicable) issuable upon such conversion only on
      the
      basis of the Conversion Rate prior to adjustment; and, in lieu of any cash,
      property or securities the issuance 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 cash, property
      or
      securities. If any distribution in respect of which an adjustment to the
      Conversion Rate is required to be made as of the record date, Determination
      Date
      or Expiration Date therefore 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 record
      date, Determination Date or Expiration Date had not occurred. 

     

    
      
        
        

      

      
        38

        
          

        

      

      
        
        

      

    

    (c)  For
      purposes of this Section 4.06, “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 or
      converted into any combination of cash, securities or other property, the date
      fixed for determination of shareholders entitled to receive such cash, security
      or other property (whether or not such date is fixed by the Board of Directors
      or by statute, contract or otherwise). 

     

    (d)  If
      one or
      more event occurs 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 adjustment events, as set out in this Section 4.06, during such period.
      

     

    (e)  Notwithstanding
      the provisions set forth in Section 4.06(a), in no event shall the Conversion
      Rate exceed 21.3858 per $1,000 principal amount of Securities, subject to
      adjustment in the manner set forth in clauses (1) through (4) of Section
      4.06(a).

     

    Section
      4.07.  No
      Adjustment.
      No
      adjustment in the Conversion Rate shall be required if Holders may participate
      in the transactions set forth in Section 4.06 above (to the same extent as
      if
      the Securities had been converted into Common Stock immediately prior to such
      transactions) without converting the Securities held by such Holders.

     

    (a)  No
      adjustment in the Conversion Rate shall be required unless such adjustment
      would
      require an increase or decrease of at least 1% in the Conversion Rate as last
      adjusted; provided, however, that any adjustments which would be required to
      be
      made but for this Section 4.07(b) shall be carried forward and taken into
      account in any subsequent adjustment. Notwithstanding the foregoing, all
      adjustments not previously made shall have effect with respect to any conversion
      on or after October 15, 2013. All calculations under this Article 4 shall be
      made to the nearest cent or to the nearest one-ten thousandth of a share, as
      the
      case may be, with one half cent and 0.00005 of a share, respectively, being
      rounded upward.

     

    (b)  No
      adjustment in the Conversion Rate shall be required for (1) issuances of
      Common Stock pursuant to any present or future plan of the Company providing
      for
      the reinvestment of dividends or interest and the investment of additional
      optional amounts of Common Stock under any plan, (2) issuances of Common
      Stock or options or rights to purchase 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, (3) issuances of Common Stock
      pursuant to any option, warrant, right or exercisable, exchangeable or
      convertible security not described in clause (2) above and outstanding as of
      the
      Issue Date or (4) for accrued and unpaid interest and Additional Interest
      owed, if any.

     

    (c)  To
      the
      extent that the Securities become convertible into the right to receive cash
      in
      accordance with the provision of Section 4.10, no adjustment need be made
      thereafter as to the cash.

     

    
      
        
        

      

      
        39

        
          

        

      

      
        
        

      

    

    Section
      4.08.  Notice
      of Adjustment.

     

    Whenever
      the Conversion Rate or conversion privilege is required to be adjusted pursuant
      to this Indenture, the Company shall promptly mail to Holders a notice of the
      adjustment and file with the Trustee an Officers’ Certificate briefly stating
      the facts requiring the adjustment and the manner of computing it. Failure
      to
      mail such notice or any defect therein shall not affect the validity of any
      such
      adjustment. 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
      4.09.  Notice
      of Certain Transactions.

     

    In
      the
      event that there is a dissolution or liquidation of the Company, the Company
      shall mail to Holders and file with the Trustee a notice stating the proposed
      effective date. The Company shall mail such notice at least 10 days before
      such
      proposed effective date. Failure to mail such notice or any defect therein
      shall
      not affect the validity of any transaction referred to in this Section
      4.09.

     

    Section
      4.10.  Effect
      of Recapitalization, Reclassification, Consolidation, Merger or
      Sale.

     

    If
      any of
      following events occur (each, a “Business Combination”):

     

    (1)  any
      recapitalization, reclassification or change of the Common Stock, other than
      changes resulting from a subdivision or a combination, 

     

    (2)  a
      consolidation, merger or combination involving the Company, 

     

    (3)  a
      sale,
      conveyance or lease to another corporation of all or substantially all of the
      property and assets of the Company, other than to one or more of the Company’s
      subsidiaries, or 

     

    (4)  any
      statutory share exchange,

     

    in
      each
      case as a result of which holders of Common Stock are entitled to receive stock,
      other securities, other property or assets (including cash or any combination
      thereof) with respect to or in exchange for Common Stock, the Company or the
      successor or purchasing corporation, as the case may be, shall execute with
      the
      Trustee a supplemental indenture (which shall comply with the TIA as in force
      at
      the date of execution of such supplemental indenture if such supplemental
      indenture is then required to so comply) providing that the settlement of the
      Conversion Value will be based on the kind and amount of shares of stock, other
      securities or other property or assets (including cash or any combination
      thereof) which Holders of Common Stock receive in such Business Combination
      in
      respect of each share of Common Stock. In the event holders of Common Stock
      have
      the opportunity to elect the form of consideration to be received in such
      Business Combination, the Company shall make adequate provision whereby the
      Securities shall be convertible from and after the effective date of such
      Business Combination into the form of consideration elected by a majority of
      the
      Company’s shareholders in such Business 

     

    
      
        
        

      

      
        40

        
          

        

      

      
        
        

      

    

    Combination.
      Appropriate provisions will be made, as determined in good faith by the
      Company’s Board of Directors, to preserve the settlement provisions in Section
      4.13 following such Business Combination to the extent feasible. The Company
      may
      not become a party to any such transaction unless its terms are consistent
      with
      this Section 4.10. Such supplemental indenture shall provide for adjustments
      which shall be as nearly equivalent as may be practicable to the adjustments
      provided for in this Article 4. If, in the case of any such Business
      Combination, the stock or other securities and assets receivable thereupon
      by a
      holder of shares of Common Stock includes shares of stock or other securities
      and assets of a corporation other than the successor or purchasing corporation,
      as the case may be, in such Business Combination, then such supplemental
      indenture shall also be executed by such other corporation and shall contain
      a
      full and unconditional guarantee by such other corporation of all the Company’s
      obligations under the Indenture and the Securities and such additional
      provisions to protect the interests of the Holders of the Securities as the
      Board of Directors shall reasonably consider necessary by reason of the
      foregoing, including to the extent practicable the provisions providing for
      the
      repurchase rights set forth in Article 3 hereof. Notwithstanding anything
      contained in this Section, and for the avoidance of doubt, this Section shall
      not affect the right of a Holder to convert its Securities into shares of Common
      Stock prior to the effective date of the Business Combination.

     

    Section
      4.11.  Trustee’s
      Disclaimer.

     

    The
      Trustee shall have no duty to determine when an adjustment under this Article
      4
      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, 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 4.08. The Trustee makes
      no representation as to the validity or value of any securities or assets issued
      upon conversion of Securities. 

     

    Section
      4.12.  [Intentionally
      Omitted] 

     

    Section
      4.13.  Settlement
      of Conversion Obligation.

     

    (a)  Holders
      surrendering Securities for conversion shall receive for each $1,000 principal
      amount of Securities surrendered for conversion:

     

    (A)  cash
      in
      an amount equal to the lesser of (1) $1,000 and (2) the Conversion Value;
      and

     

    (B)  if
      the
      Conversion Value is greater than $1,000, a number of shares of Common
      Stock
      (the
“Remaining Shares”) equal to the sum of the Daily Share Amounts for each of the
      20 consecutive Trading Days in the Conversion Reference Period, appropriately
      adjusted to reflect stock splits, stock dividends, combinations or similar
      events occurring during the Conversion Reference Period, subject to the
      Company’s right to deliver cash in lieu of all or a portion of such Remaining
      Shares as set forth in Section 4.13(b);

     

    
      
        
        

      

      
        41

        
          

        

      

      
        
        

      

    

    provided
      that in no event shall the aggregate number of Remaining Shares, per $1,000
      principal amount of Securities, exceed the Aggregate Share Cap.

     

    (b)  On
      any
      day prior to the first Trading Day of the applicable Conversion Reference
      Period, the Company may specify 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, the amount of cash that the Company will deliver in respect
      of
      each Trading Day in the applicable Conversion Reference Period will equal the
      product of: (1) the Cash Percentage, (2) the Daily Share Amount for such Trading
      Day and (3) the Volume Weighted Average Price of the Common Stock for such
      Trading Day (provided that after the consummation of a Fundamental Change in
      which the consideration is comprised entirely of cash, the amount used in this
      clause (3) will be the cash price per share received by holders of the Common
      Stock in such Fundamental Change). The number of shares that the Company shall
      deliver in respect of each Trading Day in the applicable Conversion Reference
      Period will be a percentage of the Daily Share Amount equal to 100% minus the
      Cash Percentage. Upon making a determination that a percentage of the Daily
      Share Amount will be settled in cash, the Company shall promptly issue a press
      release and disclose such information on its website prior to the first Trading
      Day of the applicable Conversion Reference Period. If the Company does not
      specify a Cash Percentage by the start of the applicable Conversion Reference
      Period, the Company shall be required to 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 the Company shall pay cash in lieu
      of
      fractional shares otherwise issuable upon conversion of Securities.

     

    (c)  The
      Company shall determine the Conversion Value, Daily Share Amount and the number
      of shares of Common Stock, if any, to be issued upon conversion at the end
      of
      the applicable Conversion Reference Period. Upon conversion of a Security,
      the
      Company shall pay the cash and deliver the shares of Common Stock, as
      applicable, as promptly as practicable after the last Trading Day of the
      Conversion Reference Period but in any event not later than the third Trading
      Day following the last Trading Day of the Conversion Reference
      Period.

     

    For
      the
      purposes of Sections 4.13(a) and (b), in the event that any of Conversion Value,
      Daily Share Amounts or Volume Weighted Average Price cannot be determined 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
      Conversion Value, Daily Share Amounts and Volume Weighted Average Price, as
      applicable.

      punctually paid or duly provided for, on any Interest Payment Date shall be
      paid
      to the Person in whose name that Security is registered at the close of business

      Purchase Price and Additional Interest, if any, in each case if payable, shall
      be considered paid on the applicable date due if on such date the Trustee or
      the
      Paying Agent holds, in accordance with this Indenture, money sufficient to

      all such amounts then due. The Company shall, to the fullest extent permitted
      by
      law, pay interest in immediately available funds on overdue principal amount
      and
      interest at the annual rate borne by the Securities compounded semiannually,
      which interest shall accrue from the date such overdue amount was originally
      due
      to the date payment of such amount, including interest thereon, has been made

      is legal tender for payment of public and private debts; provided, however,
      that
      at the option of the Company payment of interest may be made by check mailed
      to
      the address of the Person entitled thereto as such address appears in the
      Register; provided further that a Holder with an aggregate principal amount
      in
      excess of $2,000,000 will be paid by wire transfer in immediately available
      funds at the election of such Holder if such Holder has provided wire transfer
      instructions to the Trustee at least 10 Business Days prior to the payment
      date.
      Any wire transfer instructions received by the Trustee will remain in effect
      until revoked by the Holder.

      Act, and within 15 days after it files them with the SEC, the Company shall
      file
      copies of all such reports, information and other documents with the Trustee;
      provided that any such reports, information and documents filed with the SEC
      pursuant to its Electronic Data Gathering, Analysis and Retrieval (or EDGAR)
      system shall be deemed to be filed with the Trustee. The Company also shall
      comply with the provisions of TIA Section 314(a). 

     

    (b)  Delivery
      of such reports, information and documents to the Trustee is for informational
      purposes only and the Trustee’s receipt of such 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).

      of the Company’s compliance with all terms, conditions and covenants on its part
      contained in this Indenture and stating whether or not the signer knows of

      of
      Default, the Officers’ Certificate shall describe the Default or Event of
      Default and the efforts to remedy the same. For the purposes of this Section
      5.03, compliance shall be determined without regard to any grace period or
      requirement of notice provided pursuant to the terms of this
      Indenture.

     

    Section

      Instruments and Acts.

     

    Upon
      request of the Trustee, the Company will execute and deliver such further
      instruments and do such further acts as may be reasonably necessary or proper
      to
      carry out more effectively the purposes of this Indenture.

    During
      the period prior to the expiration of the holding period applicable to sales

      the Company covenants and agrees that it shall, during any period in which
      it is
      not subject to Section 13 or 15(d) under the Exchange Act, upon the request
      of
      any Holder or beneficial holder of the Securities, make available to such Holder
      or beneficial holder of Securities or any Common Stock issued upon conversion
      thereof which continue to be Restricted Securities in connection with any sale
      thereof and any prospective purchaser of Securities or such Common Stock
      designated by such Holder or beneficial holder, the information required
      pursuant to Rule 144A(d)(4) under the Securities Act and it will take such
      further action as any Holder or beneficial holder of such Securities or such
      Common Stock may reasonably request, all to the extent required from time to
      time to enable such Holder or beneficial holder to sell its Securities or Common
      Stock without registration under the Securities Act within the limitation of
      the
      exemption provided by Rule 144A, as such Rule may be amended from time to time.

    Section
      5.07.  Stay,
      Extension and Usury Laws.

     

    The
      Company covenants (to the extent that it may lawfully do so) that it shall
      not
      at any time insist upon, plead or in any manner whatsoever claim or take the
      benefit or advantage of, any stay, extension or usury law or other law which
      would prohibit or forgive the Company from paying all or any portion of the
      principal of or accrued but unpaid interest or Additional Interest, if any,
      on
      the Securities as contemplated herein, wherever enacted, now or at any time
      hereafter in force, or which may affect the covenants or the performance of
      this
      Indenture, and the

    Company
      (to the extent it may lawfully do so) hereby expressly waives all benefit or
      advantage of any such law and covenants that it will not, by resort to any
      such
      law, hinder, delay or impede the execution of any power herein granted to the
      Trustee, but will suffer and permit the execution of every such power as though
      no such law had been enacted.

     

    Section
      5.08.  Payment
      of Additional Interest.

     

    If

      Rights Agreement, the Company shall deliver to the Trustee an Officers’
Certificate to that effect stating (i) the amount of such Additional Interest
      that is payable, (ii) the reason why such Additional Interest is payable and
      (iii) the date on which such Additional Interest is payable. Unless and until
      a
      Trust Officer of the Trustee receives such a certificate, the Trustee may assume
      without inquiry that no such Additional Interest is payable. If the Company
      has
      paid Additional Interest directly to the Persons entitled to such Additional
      Interest, the Company shall deliver to the Trustee a certificate setting forth
      the particulars of such payment.

     

    Section
      5.09.  Maintenance
      of Office or Agency.

     

    The
      Company will maintain an office or agency of the Trustee, Registrar and Paying
      Agent where securities may be presented or surrendered for payment, where
      Securities may be surrendered for registration of transfer, purchase or
      redemption and where notices and demands to or upon the Company in respect
      of
      the Securities and this Indenture may be served. The Corporate Trust Office
      shall initially be one such office or agency for all of the aforesaid purposes.
      The Company shall give prompt written notice to the Trustee of the location,
      and
      of any change in the location, of any such office or agency (other than a change
      in the location of the office of the Trustee). If at any time the Company shall
      fail to maintain any such required office or agency or shall fail to furnish
      the
      Trustee with the address thereof, such presentations, surrenders, notices and
      demands may be made or served at the address of the Trustee set forth in Section
      11.02.

     

    The
      Company may also from time to time designate one or more other offices or
      agencies where the Securities may be presented or surrendered for any or all
      such purposes and may from time to time rescind such designations; provided,
      however, that no such designation or rescission shall in any manner relieve
      the
      Company of its obligation to maintain an office or agency.

      “Notice of Default”), and the Company does not cure the Default within the time
      specified in clause (5) or (6) of Section 7.01(a), as applicable, after receipt

      to
      this Indenture.

    Section
      7.02.  Acceleration.

     

    If
      an
      Event of Default (other than an Event of Default specified in clause (8) or
      (9)
      of Section 7.01(a)) occurs and is continuing with respect to the Company, the
      Trustee may, by notice to the Company, or the Holders of at least 25% in
      aggregate principal amount of the Securities then outstanding may, by notice
      to
      the Company and the Trustee, declare the principal amount and accrued and unpaid
      interest, if any, and accrued and unpaid Additional Interest, if any, through
      the date of declaration on all the Securities to be immediately due and payable.
      Upon such a declaration, such principal amount and such accrued and unpaid
      interest, if any, and such accrued and unpaid Additional Interest, if any,
      shall
      be due and payable immediately. If an Event of Default specified in Section
      7.01(a)(8) or (9) occurs in respect of the Company and is continuing, the
      principal amount and accrued but unpaid interest, if any, and accrued and unpaid
      Additional Interest, if any, on all the Securities shall become and be
      immediately due and payable without any declaration or other act on the part
      of
      the Trustee or any Holders of Securities. The Holders of a majority in aggregate
      principal amount of the Securities then outstanding by notice to the Trustee
      may
      rescind an acceleration and its consequences if (a) all existing Events of
      Default, other than the nonpayment of the principal of the Securities which
      have
      become due solely by such declaration of acceleration, have been cured or
      waived; (b) to the extent the payment of such interest is lawful, interest
      (calculated at the rate per annum borne by the Securities) on overdue
      installments of interest and overdue principal, which has become due otherwise
      than by such declaration of acceleration, has been paid; (c) the rescission
      would not conflict with any judgment or decree of a court of competent
      jurisdiction; and (d) all payments due to the Trustee and any predecessor
      Trustee under Section 8.07 have been made. No such rescission shall affect
      any
      subsequent Default or impair any right consequent thereto.

     

    Section
      7.03.  Other
      Remedies.

     

    (a)  Subject
      to Section 8.01(a), 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 payment of the principal amount and accrued and
      unpaid interest, if any, and accrued and unpaid Additional Interest, if any,
      on
      the Securities or to enforce the performance of any provision of the Securities
      or this Indenture. 

     

    (b)  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 Holder 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
      applicable law.

     

    Section
      7.04.  Waiver
      of Defaults and Events of Default.

     

    Subject
      to Sections 7.07 and 10.02, the Holders of a majority in aggregate principal
      amount of the Securities then outstanding by notice to the Trustee may waive
      an
      existing Default or Event of Default and its consequences, except an uncured
      Default or Event of Default in the payment of the principal of, premium, if
      any,
      or any accrued but unpaid interest on any Security, an uncured failure by the
      Company to convert any Securities into Common Stock and cash, as 

     

    
      
        
        

      

      
        49

        
          

        

      

      
        
        

      

    

    applicable,
      or any Default or Event of Default in respect of any provision of this Indenture
      or the Securities which, under Section 10.02, cannot be modified or amended
      without the consent of the Holder of each Security affected. When a Default
      or
      Event of Default is waived, it is cured and ceases to exist.

     

    Section
      7.05.  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. 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 satisfactory to it; provided, however, that the Trustee may take
      any
      other action deemed proper by the Trustee which is not inconsistent with such
      direction.

     

    Section
      7.06.  Limitations
      on Suits.

     

    (a)  A
      Holder
      may not pursue any remedy with respect to this Indenture or the Securities
      (except actions for payment of overdue principal, premium, if any, or interest
      or for the conversion of the Securities pursuant to Article 4)
      unless:

     

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

     

    (2)  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;

     

    (3)  such
      Holder or Holders offer to the Trustee reasonable security or indemnity to
      the
      Trustee against any loss, liability or expense; 

     

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

     

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

     

    (b)  No
      Holder
      of a Security shall have any right under any provision of this Indenture or
      the
      Securities to affect, disturb, or prejudice the rights of another Holder of
      a
      Security or to obtain a preference or priority over another Holder of a
      Security.

     

    Section
      7.07.  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 of the principal amount, interest, Fundamental Change Purchase
      Price, if any, or Additional Interest, if any, in respect of the Securities
      held
      by such Holder, on or after the respective due dates expressed in the Securities
      and this Indenture (whether upon 

     

    
      
        
        

      

      
        50

        
          

        

      

      
        
        

      

    

    repurchase
      or otherwise), and to convert such Security in accordance with Article 4, and
      to
      bring suit for the enforcement of any such payment on or after such respective
      due dates or for the right to convert in accordance with Article 4, is absolute
      and unconditional and shall not be impaired or affected without the consent
      of
      the Holder.

     

    Section
      7.08.  Collection
      Suit by Trustee.

     

    If
      an
      Event of Default described in clause (1) or (2) of Section 7.01(a) 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 such further amount
      as
      shall be sufficient to cover the costs and expenses of collection, including
      the
      reasonable compensation, expenses, disbursements and advances of the Trustee,
      its agents and counsel.

     

    Section
      7.09.  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 Receiver 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 8.07, 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
      7.10.  Priorities.

     

    (a)  If
      the
      Trustee collects any money pursuant to this Article 7, it shall pay out the
      money in the following order:

     

    (1)  First,
      to
      the Trustee for amounts due under Section 8.07; 

     

    (2)  Second,
      to Holders for amounts due and unpaid on the Securities for the principal
      amount, interest, and Additional Interest, as applicable, ratably, without
      preference or priority of any kind, according to such respective amounts due
      and
      payable on the Holders’ Securities; 

     

    
      
        
        

      

      
        51

        
          

        

      

      
        
        

      

    

    (3)  Third,
      to
      such other Person or Persons, if any, to the extent entitled thereto; and

     

    (4)  Fourth,
      the balance, if any, to the Company. 

     

    (b)  The
      Trustee may fix a record date and payment date for any payment to Holders
      pursuant to this Section 7.10.

     

    Section
      7.11.  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 7.11
      does not apply to a suit made by the Trustee, a suit by a Holder pursuant to
      Section 7.07 or a suit by Holders of more than 10% in aggregate principal amount
      of the Securities then outstanding. This Section 7.11 shall be in lieu of
      Section 315(e) of the TIA and such Section 315(e) is hereby expressly excluded
      from this Indenture, as permitted by the TIA.

     

    ARTICLE
      8

    TRUSTEE

     

    Section
      8.01.  Obligations
      of Trustee.

     

    (a)  If
      an
      Event of Default of which a Responsible Officer of the Trustee shall have actual
      knowledge has occurred and is continuing, the Trustee shall exercise such of
      the
      rights and powers vested in it by this Indenture and use the same degree of
      care
      and skill in its exercise as a prudent person would exercise or use under the
      circumstances in the conduct of his or her own affairs. 

     

    (b)  Except
      during the continuance of an Event of Default of which a Responsible Officer
      of
      the Trustee shall have actual knowledge:

     

    (1)  the
      Trustee need perform only those duties as are specifically set forth in this
      Indenture and no others; and 

     

    (2)  in
      the
      absence of bad faith on its part, the Trustee may conclusively rely, as to
      the
      truth of the statements and the correctness of the opinions expressed therein,
      upon certificates or opinions furnished to the Trustee and conforming to the
      requirements of this Indenture. The Trustee, however, shall examine any
      certificates and opinions which by any provision hereof are specifically
      required to be delivered to the Trustee to determine whether or not they conform
      to the requirements of this Indenture, but need not confirm or investigate
      the
      accuracy of mathematical calculations or other facts stated therein.

     

    
      
        
        

      

      
        52

        
          

        

      

      
        
        

      

    

    This
      Section 8.01(b) shall be in lieu of Section 315(a) of the TIA and such Section
      315(a) is hereby expressly excluded from this Indenture, as permitted by the
      TIA. 

     

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

     

    (1)  this
      paragraph does not limit the effect of Section 8.01(b); 

     

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

     

    (3)  the
      Trustee shall not be liable in its individual capacity with respect to any
      action it takes or omits to take in good faith in accordance with a direction
      received by it pursuant to Section 7.05. 

     

    This
      Section 8.01(c) shall be in lieu of Sections 315(d)(1), 315(d)(2) and 315(d)(3)
      of the TIA and such Sections are hereby expressly excluded from this Indenture
      as permitted by the TIA. 

     

    (d)  No
      provision of this Indenture shall require the Trustee to expend or risk its
      own
      funds or otherwise incur any financial liability in the performance of any
      of
      its duties hereunder or in the exercise of any of its rights or powers unless
      the Trustee shall have received adequate security or indemnity in its opinion
      against potential costs and liabilities incurred by it relating thereto.

     

    (e)  Every
      provision of this Indenture that in any way relates to the Trustee is subject
      to
      subsections (a), (b), (c) and (d) of this Section 8.01. 

     

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

     

    Section
      8.02.  Rights
      of Trustee.

     

    (a)  Subject
      to Section 8.01:

     

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

     

    
      
        
        

      

      
        53

        
          

        

      

      
        
        

      

    

    (2)  Before
      the Trustee acts or refrains from acting, it may require an Officers’
Certificate or an Opinion of Counsel, which shall conform to Section 11.04(b).
      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.

     

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

     

    (4)  The
      Trustee shall not be personally liable for any action it takes or omits to
      take
      in good faith which it believes to be authorized or within its rights or powers.
      

     

    (5)  The
      Trustee may consult with counsel of its selection, and the advice or opinion
      of
      such counsel as to matters of law shall be full and complete authorization
      and
      protection in respect of any such action taken, omitted or suffered by it
      hereunder in good faith and in accordance with the advice or opinion of such
      counsel. 

     

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

     

    (7)  The
      Trustee shall not be bound to make any investigation into the facts or matters
      stated in any resolution, certificate, statement, instrument, opinion, report,
      notice, request, direction, consent, order, bond, debenture, note, other
      evidence of indebtedness or other paper or document, but the Trustee, in its
      discretion, may make such further inquiry or investigation into such facts
      or
      matters as it may see fit, and, if the Trustee shall determine to make such
      further inquiry or investigation, it shall be entitled to examine the books,
      records and premises of the Company, 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. The reasonable expense
      of every such examination shall be paid by the Company or, if paid by the
      Trustee, shall be repaid by the Company upon demand from the Company’s own
      funds. 

     

    (8)  The
      Trustee shall not be deemed to have notice or knowledge of any Default, Event
      of
      Default, or Fundamental Change unless a Responsible Officer of the Trustee
      has
      actual knowledge thereof or unless written notice of any event which is in
      fact
      such a Default is received by the Trustee at the Corporate Trust Office, and
      such notice references the Securities and this Indenture. In the absence of
      receipt of such notice or actual knowledge, the Trustee may conclusively assume
      that there is no Default, Event of Default, or Fundamental Change. 

     

    
      
        
        

      

      
        54

        
          

        

      

      
        
        

      

    

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

     

    (10)  The
      right
      of the Trustee to perform any discretionary act enumerated in this Indenture
      shall not be construed as a duty, and the Trustee shall not be answerable for
      other than its own gross negligence or willful misconduct in the performance
      of
      such act. 

     

    Section
      8.03.  Individual
      Rights of Trustee.

     

    The
      Trustee in its individual or any other capacity may become the owner or pledgee
      of Securities and may otherwise deal with the Company or an Affiliate of the
      Company with the same rights it would have if it were not Trustee. Any Agent
      may
      do the same with like rights. However, the Trustee is subject to Sections 8.10
      and 8.11.

     

    Section
      8.04.  Trustee’s
      Disclaimer.

     

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

     

    Section
      8.05.  Notice
      of Default or Events of Default.

     

    If
      a
      Default or an Event of Default occurs and is continuing and if it is known
      to
      the Trustee, the Trustee shall mail to each Holder of a Security notice of
      all
      uncured Defaults or Events of Default known to it within 90 days after it occurs
      or, if later, within 15 days after it becomes known to the Trustee. However,
      the
      Trustee may withhold the notice if and for so long as a committee of its Trust
      Officers in good faith determines that withholding notice is in the interests
      of
      Holders of Securities, except in the case of a Default or an Event of Default
      in
      payment of the principal of, or premium, if any, or interest on any Security
      when due or in the payment of any redemption or purchase obligation, or the
      Company’s failure to convert Securities when obligated to convert them. This
      Section 8.05 is in lieu of section 315(b) of the TIA and such provision is
      expressly excluded from this Indenture as permitted by the TIA.

     

    Section
      8.06.  Reports
      by Trustee to Holders.

     

    (a)  If
      a
      report is required by TIA Section 313, within 60 days after each May 15,
      beginning with the May 15 following the date of this Indenture, the Trustee
      shall mail to each Holder of Securities a brief report dated as of such May
      15
      that complies with TIA Section 313(a). If required by TIA Section 313, the
      Trustee also shall comply with TIA Sections 313(b)(2) and (c). 

     

    
      
        
        

      

      
        55

        
          

        

      

      
        
        

      

    

    (b)  A
      copy of
      each report at the time of its mailing to Holders of Securities shall be mailed
      to the Company and, to the extent required by the TIA, filed with the SEC,
      and
      each stock exchange, if any, on which the Securities are listed. The Company
      shall notify the Trustee whenever the Securities become listed on any stock
      exchange or listed or admitted to trading on any quotation system and any
      changes in the stock exchanges or quotation systems on which the Securities
      are
      listed or admitted to trading and of any delisting thereof. 

     

    Section
      8.07.  Compensation
      and Indemnity.

     

    (a)  The
      Company shall pay to the Trustee from time to time such compensation (as agreed
      to from time to time by the Company and the Trustee in writing) for its services
      (which compensation shall not be limited by any provision of law in regard
      to
      the compensation of a trustee of an express trust). The Company shall reimburse
      the Trustee upon request for all reasonable disbursements, expenses and advances
      incurred or made by it. Such expenses may include the reasonable compensation,
      disbursements and expenses of the Trustee’s agents and counsel. 

     

    (b)  The
      Company shall indemnify the Trustee or any predecessor Trustee (which for
      purposes of this Section 8.07 shall include its officers, directors, employees
      and agents) for, and hold it harmless against, any and all loss, liability
      or
      expense including taxes (other than franchise taxes and taxes based upon,
      measured by or determined by the income of the Trustee), incurred by it arising
      out of or in connection with the acceptance or administration of its duties
      under this Indenture or any action or failure to act as authorized or within
      the
      discretion or rights or powers conferred upon the Trustee hereunder including
      the reasonable costs and expenses of the Trustee and its counsel in defending
      (including reasonable legal fees and expenses) itself against any claim or
      liability in connection with the exercise or performance of any of its powers
      or
      duties hereunder. The Trustee shall notify the Company promptly of any claim
      asserted against the Trustee for which it may seek indemnity. The Company need
      not pay for any settlement effected without its prior written consent, which
      shall not be unreasonably withheld. Anything in this Indenture to the contrary
      notwithstanding, in no event shall the Trustee be liable for special, indirect
      or consequential loss or damage of any kind whatsoever (including but not
      limited to lost profits), even if the Trustee has been advised of the likelihood
      of such loss or damage and regardless of the form of action. 

     

    (c)  The
      Company need not reimburse the Trustee for any expense or indemnify it against
      any loss or liability incurred by it resulting from its gross negligence,
      willful misconduct or bad faith. 

     

    (d)  The
      Trustee shall have a senior claim to which the Securities are hereby made
      subordinate on all money or property held or collected by the Trustee. The
      obligations of the Company under this Section 8.07 shall survive the
      satisfaction and discharge of this Indenture or the resignation or removal
      of
      the Trustee. 

     

    (e)  When
      the
      Trustee incurs expenses or renders services after an Event of Default specified
      in clause (8) or (9) of Section 7.01(a) occurs, the expenses and the
      compensation for the services are intended to constitute expenses of
      administration under any Bankruptcy Law. The provisions of this Section shall
      survive the termination of this Indenture.

    Section
      8.08.  Replacement
      of Trustee.

     

    (a)  The
      Trustee may resign by so notifying the Company. The Holders of a majority in
      aggregate principal amount of the Securities then outstanding may remove the
      Trustee by so notifying the Trustee and the Company and may, with the Company’s
      written consent, appoint a successor Trustee. The Company may remove the Trustee
      at any time, so long as no Default or Event of Default has occurred and is
      continuing, and appoint a Successor Trustee in accordance with this Section
      8.08. 

     

    (b)  If
      the
      Trustee resigns or is removed or if a vacancy exists in the office of Trustee
      for any reason, the Company shall promptly appoint a successor Trustee. If
      the
      Company fails to promptly appoint a successor Trustee, the Trustee shall have
      the right to choose a qualified Trustee as successor, and the Company shall
      appoint such successor as Trustee. The resignation or removal of a Trustee
      shall
      not be effective until a successor Trustee shall have delivered the written
      acceptance of its appointment as described below. 

     

    (c)  If
      a
      successor Trustee does not take office within 30 days after the retiring Trustee
      resigns or is removed, the retiring Trustee, the Company or the Holders of
      10%
      in principal amount of the Securities then outstanding may petition any court
      of
      competent jurisdiction for the appointment of a successor Trustee at the expense
      of the Company. 

     

    (d)  If
      the
      Trustee fails to comply with Section 8.10, any Holder may petition any court
      of
      competent jurisdiction for the removal of the Trustee and the appointment of
      a
      successor Trustee. 

     

    (e)  A
      successor Trustee shall deliver a written acceptance of its appointment to
      the
      retiring Trustee and to the Company. Immediately after that, the retiring
      Trustee shall transfer all property held by it as Trustee to the successor
      Trustee and be released from its obligations (exclusive of any liabilities
      that
      the retiring Trustee may have incurred while acting as Trustee) hereunder,
      the
      resignation or removal of the retiring Trustee shall become effective, and
      the
      successor Trustee shall have all the rights, powers and duties of the Trustee
      under this Indenture. A successor Trustee shall mail notice of its succession
      to
      each Holder. 

     

    (f)  A
      retiring Trustee shall not be liable for the acts or omissions of any successor
      Trustee after its succession. 

     

    (g)  Notwithstanding
      replacement of the Trustee pursuant to this Section 8.08, the Company’s
      obligations under Section 8.07 shall continue for the benefit of the retiring
      Trustee.

     

    Section
      8.09.  Successor
      Trustee by Merger, Etc.

     

    If
      the
      Trustee consolidates with, merges or converts into, or transfers all or
      substantially all of its corporate trust business (including the administration
      of this Indenture) to, another corporation, the resulting, surviving or
      transferee corporation, without any further act, shall be the successor Trustee;
      provided such transferee corporation shall qualify and be eligible under Section
      8.10. Such successor Trustee shall promptly mail notice of its succession to
      the
      Company and each Holder.

    Section
      8.10.  Eligibility;
      Disqualification.

     

    The
      Trustee shall always satisfy the requirements of paragraphs (1), (2) and (5)
      of
      TIA Section 310(a). The Trustee (or its parent holding company) shall have
      a
      combined capital and surplus of at least $50,000,000 as set forth in its most
      recent published annual report of condition. If at any time the Trustee shall
      cease to satisfy any such requirements, it shall resign immediately in the
      manner and with the effect specified in this Article 8. The Trustee shall be
      subject to the provisions of TIA Section 310(b). Nothing herein shall prevent
      the Trustee from filing with the SEC the application referred to in the
      penultimate paragraph of TIA Section 310(b). 

     

    Section
      8.11.  Preferential
      Collection of Claims Against Company.

     

    The
      Trustee shall comply with TIA Section 311(a), excluding any creditor
      relationship listed in TIA Section 311(b). A Trustee who has resigned or been
      removed shall be subject to TIA Section 311(a) to the extent indicated
      therein.

    (a)  This

      which have been destroyed, lost or stolen and which have been replaced or paid
      as provided in Section 2.07 and (ii) Securities for whose payment money has
      theretofore been deposited in trust and thereafter repaid to the Company as

      or any of its Affiliates) or a Conversion Agent, if applicable, immediately
      available funds in trust for the purpose of and in an amount sufficient to

      and discharge all indebtedness and obligations related to such Securities not
      theretofore delivered to the Trustee for cancellation, for principal and

    (3)  the

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

     

    (b)  Notwithstanding
      the satisfaction and discharge of this Indenture, the obligations of the Company
      with respect to the conversion privilege and the Conversion Rate of the
      Securities pursuant to Article 4, the obligations of the Company to the Trustee
      under Section 8.07 and, if money shall have been deposited with the Trustee

      shall survive until the Securities have been paid in full. 

     

    Section
      9.02.  Application
      of Trust Money.
      Subject
      to the provisions of Section 9.03, the Trustee or a Paying Agent shall hold
      in
      trust, for the benefit of the Holders, all money deposited with it pursuant
      to
      Section 9.01 and shall apply the deposited money in accordance with this
      Indenture and the Securities to the payment of the principal of and interest
      on
      the Securities.

     

    Section
      9.03.  Repayment
      to Company.

      any
      excess money (1) deposited with them pursuant to Section 9.01 and (2) held
      by
      them at any time. 

     

    (a)  The
      Trustee and each Paying Agent shall, subject to applicable abandonment property
      laws, pay to the Company upon request any money held by them for the payment
      of
      principal or interest that remains unclaimed for two years after a right to
      such
      money has matured; provided, however, that the Trustee or such Paying Agent,
      before being required to make any such payment, may at the expense of the
      Company cause to be mailed to each Holder entitled to such money notice that
      such money remains unclaimed and that after a date specified therein, which
      shall be at least 30 days from the date of such mailing, any unclaimed balance
      of such money then remaining will be repaid to the Company. After payment to
      the
      Company, Holders entitled to money must look to the Company for payment as
      general creditors unless an applicable abandoned property law designates another
      person. 

     

    Section
      9.04.  Reinstatement.
      If the

      Section 9.02 by reason of any legal proceeding or by reason of any order or
      judgment of any court or governmental authority enjoining, restraining or
      otherwise prohibiting such application, then the Company’s obligations under
      this Indenture and the Securities shall be revived and reinstated as though
      no
      deposit had occurred pursuant to Section 9.01 until such time as the Trustee
      or
      such Paying Agent is permitted to apply all such money in accordance with
      Section 9.02; provided, however, that if the Company has made any payment of
      the
      principal of or interest on any Securities because of the reinstatement of
      its
      obligations, the Company shall be subrogated to the rights of the Holders of
      such Securities to receive any such payment from the money held by the Trustee
      or such Paying Agent.

      The
      Company and the Trustee may amend or supplement this Indenture or the Securities
      with the written consent of the Holders of not less than a majority in aggregate
      principal amount of the Securities then outstanding. However, subject to Section
      10.04, without the written consent of each Holder affected, an amendment,
      supplement or waiver may not:

     

    (1)  alter

      to modify or amend this Indenture or to waive any past Default or otherwise
      change the provisions in this Indenture that relate to modifying or amending
      this Indenture. 

     

    (b)  Without
      limiting the provisions of Section 10.02(a) hereof, the Holders of a majority
      in
      principal amount of the Securities then outstanding may, on behalf of all the
      Holders of all Securities, (i) waive compliance by the Company with the
      restrictive provisions of this Indenture, and (ii) waive any past Default or
      Event of Default under this Indenture and its consequences, except a default
      in
      the payment when due of the principal amount, accrued and unpaid interest,

      amendment, supplement or waiver under this Section 10.02 becomes effective,
      the
      Company shall promptly 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
      10.03.  Compliance
      with Trust Indenture Act.
      Every
      amendment to or supplement of this Indenture or the Securities shall comply

      the TIA as in effect at the date of such amendment or supplement. 

     

    Section
      10.04.  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.

     

    (a)  After
      an
      amendment, supplement or waiver becomes effective, it shall bind every Holder
      of
      a Security. 

     

    Section
      10.05.  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
      10.06.  Trustee
      to Sign Amendments, Etc.The
      Trustee shall sign any amendment or supplemental indenture authorized pursuant
      to this Article 10 if the amendment or supplemental indenture does not adversely
      affect the rights, duties, liabilities or immunities of the Trustee. If it
      does,
      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
      entitled to receive and, subject to Section 8.01, shall be fully protected
      in
      relying upon, an Opinion of Counsel stating that such amendment or supplemental
      indenture is authorized or permitted by this Indenture. The Company may not
      sign
      an amendment or supplement indenture until the Board of Directors approves
      it.

     

    Section
      10.07.  Effect
      of Supplemental Indentures.
      Upon
      the execution of any supplemental indenture under this Article 10, 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.

      CONVERTIBLE SENIOR NOTES DUE 2013 

     

    1.  INTEREST

     

    Chattem,
      Inc., a Tennessee corporation (the “Company”, which term shall include any
      successor corporation under the Indenture hereinafter referred to), promises
      to
      pay interest on the principal amount of this Security at the rate of 2.00%
      per
      annum. The Company shall pay interest semiannually on November 15 and
      May 15 of each year (each, an “Interest Payment Date”), commencing
      May 15, 2007. Each payment of interest will include interest accrued
      through the day before the relevant Interest Payment Date (or purchase date).
      Cash interest will be computed on the basis of a 360-day year comprised of
      twelve 30-day months. Any payment required to be made on a day that is not
      a
      Business Day shall be made on the next succeeding Business Day. Any reference
      herein to interest accrued or payable as of any date shall include any
      Additional Interest accrued or payable on such date as provided in the
      Registration Rights Agreement.

     

    No
      sinking fund is provided for the Securities.

     

    2.  METHOD
      OF
      PAYMENT

     

    The
      Company shall pay interest on this Security (except defaulted interest) to
      the
      person who is the Holder of this Security at the close of business on
      November 1 or May 1, as the case may be (each, a “Regular Record
      Date”), next preceding the related Interest Payment Date. The Holder must
      surrender this Security to a Paying Agent to collect payment of principal.
      The
      Company will pay principal and interest in money of the United States that
      at
      the time of payment is legal tender for payment of public and private debts.
      The
      Company may pay principal and interest in respect of any Certificated Security
      by check or wire payable in such money; provided, however, that a Holder with
      an
      aggregate principal amount in excess of $2,000,000 will be paid by wire transfer
      in immediately available funds at the election of such Holder if such Holder
      has
      provided wire transfer instructions to the Trustee at least 10 Business Days
      prior to the Payment Date. The Company may mail an interest check to the
      Holder’s registered address. Notwithstanding the foregoing, so long as this
      Security is registered in the name of a Depositary or its nominee, all payments
      hereon shall be made by wire transfer of immediately available funds to the
      account of the Depositary or its nominee.

     

    Any
      wire
      transfer instructions received by the Trustee will remain in effect until
      revoked by the Holder.

     

    3.  PAYING
      AGENT, REGISTRAR AND CONVERSION AGENT

     

    Initially,
      U.S. BANK, NATIONAL ASSOCIATION (the “Trustee”, which term shall include any
      successor trustee under the Indenture hereinafter referred to) will act as
      Paying Agent, Registrar and Conversion Agent. The Company may change any Paying
      Agent, Registrar or Conversion Agent without notice to the Holder. The Company
      or any of its Subsidiaries may, subject to certain limitations set forth in
      the
      Indenture, act as Paying Agent or Registrar. 

     

    
      
        
        

      

      
        A-5

        
          

        

      

      
        
        

      

    

    4.  INDENTURE,
      LIMITATIONS

     

    This
      Security is one of a duly authorized issue of Securities of the Company
      designated as its 2.00% Convertible Senior Notes Due 2013 (the “Securities”),
      issued under an Indenture dated as of November 22, 2006 (together with any
      supplemental indentures thereto, the “Indenture”), between the Company and the
      Trustee. The terms of this Security include those stated in the Indenture and
      those required by or made part of the Indenture by reference to the Trust
      Indenture Act of 1939, as amended, as in effect on the date of the Indenture.
      This Security is subject to all such terms, and the Holder of this security
      is
      referred to the Indenture and said Act for a statement of them. Capitalized
      terms not otherwise defined herein have the meaning ascribed to such terms
      in
      the Indenture.

     

    The
      Securities are unsecured obligations of the Company limited to $125,000,000
      aggregate principal amount. The Indenture does not limit other debt of the
      Company, secured or unsecured. 

     

    5.  PURCHASE
      OF SECURITIES OF HOLDERS’ OPTION UPON A FUNDAMENTAL CHANGE

     

    If
      a
      Fundamental Change occurs prior to the Final Maturity Date, at the option of
      the
      Holder and subject to the terms and conditions of the Indenture, the Company
      shall become obligated to purchase for cash, all or any part specified by the
      Holder (so long as the principal amount of such part is $1,000 or an integral
      multiple of $1,000) of the Securities held by such Holder on a date specified
      by
      the Company that is not less than 30 nor more than 45 days after the Fundamental
      Change Effective Date, at a purchase price equal to 100% of the principal amount
      thereof together with accrued and unpaid interest, if any, and accrued and
      unpaid Additional Interest, if any, to, but excluding, the Fundamental Change
      Purchase Date. The Holder shall have the right to withdraw any Fundamental
      Change Purchase Notice (in whole or in a portion thereof that is $1,000 or
      an
      integral multiple of $1,000) at any time prior to the close of business on
      the
      Business Day next preceding the Fundamental Change Purchase Date by delivering
      a
      written notice of withdrawal to the Paying Agent in accordance with the terms
      of
      the Indenture.

     

    6.  CONVERSION

     

    Subject
      to and upon compliance with the provisions of the Indenture and upon the
      occurrence of the events specified in the Indenture, a Holder may surrender
      for
      conversion any Security that is $1,000 principal amount or integral multiples
      thereof. In lieu of receiving shares of Common Stock, a Holder will receive,
      for
      each $1,000 principal amount of Securities surrendered for
      conversion:

     

    
      	·  	
              cash
                in an amount equal to the lesser of (1) $1,000 and (2) the Conversion
                Value; and

            

    

     

    
      	·  	
              if
                the Conversion Value is greater than $1,000, a number of shares of
                Common
                Stock equal to the sum of the Daily Share Amounts, for each of the
                twenty
                

            

    

     

    
      
        
          
          

        

        
          A-6

          
            

          

        

        
          
          

        

      

      	 	
              consecutive
                Trading Days in the Conversion Reference Period, appropriately adjusted
                to
                reflect stock splits, stock dividends, combinations or similar events
                occurring during the Conversion Reference Period, subject to the
                Company’s
                right to deliver cash in lieu of all or a portion of such shares
                as
                described in the Indenture;

            

    

     

    provided
      that in no event shall the aggregate number of shares of Common Stock to be
      issued pursuant to the foregoing clause, per $1,000 principal amount of
      Securities, exceed the Aggregate Share Cap, as defined in the
      Indenture.

     

    The
      Conversion Rate on any Securities surrendered in connection with a Fundamental
      Change may be increased by an amount, if any, determined in accordance with
      Section 4.01(j) of the Indenture. 

     

    7.  DENOMINATIONS,
      TRANSFER, EXCHANGE

     

    The
      Securities are in registered form, without coupons, in denominations of $1,000
      principal amount and integral multiples of $1,000 principal amount. A Holder
      may
      register the transfer of or exchange Securities in accordance with the
      Indenture. The Registrar may require a Holder, among other things, to furnish
      appropriate endorsements and transfer documents.

     

    8.  PERSONS
      DEEMED OWNERS

     

    The
      Holder of a Security may be treated as the owner of it for all purposes.

     

    9.  UNCLAIMED
      MONEY

     

    If
      money
      for the payment of principal or interest remains unclaimed for two years, the
      Trustee and any Paying Agent will pay the money back to the Company at its
      written request, subject to applicable unclaimed property law and the provisions
      of the Indenture. After that, Holders entitled to money must look to the Company
      for payment as general creditors unless an applicable abandoned property law
      designates another person. 

     

    10.  AMENDMENT,
      SUPPLEMENT AND WAIVER

     

    Subject
      to certain exceptions, the Indenture or the Securities may be amended or
      supplemented with the consent of the Holders of at least a majority in aggregate
      principal amount of the Securities then outstanding, and an existing Default
      or
      Event of Default and its consequence or compliance with any provision of the
      Indenture or the Securities may be waived in a particular instance with the
      consent of the Holders of a majority in aggregate principal amount of the
      Securities then outstanding. Without the consent of or notice to any Holder,
      the
      Company and the Trustee may amend or supplement the Indenture or the Securities
      to, among other things, cure any ambiguity, defect or inconsistency or make
      any
      other change that does not adversely affect the rights of the Holders in any
      material respect.

    11.  SUCCESSOR
      ENTITY

     

    When
      a
      successor corporation assumes all the obligations of its predecessor under
      the
      Securities and the Indenture in accordance with the terms and conditions of
      the
      Indenture, the predecessor corporation (except in certain circumstances
      specified in the Indenture) shall be released from those
      obligations.

     

    12.  DEFAULTS
      AND REMEDIES

     

    An
      Event
      of Default shall occur upon the occurrence of any of the events specified in
      Section 7.01 of the Indenture. Upon the occurrence of an Event of Default,
      the
      principal amount of this Security and accrued and unpaid interest shall be
      subject to becoming due and payable on the terms set forth in the Indenture.
      Holders of Securities may, on the terms set forth in the Indenture, rescind
      and
      annul the consequences of any such acceleration. 

     

    Holders
      may not enforce the Indenture or the Securities except as provided in the
      Indenture. The Trustee may require indemnity satisfactory to it before it
      enforces the Indenture or the Securities. Subject to certain limitations,
      Holders of a majority in aggregate principal amount of the Securities then
      outstanding may direct the Trustee in its exercise of any trust or power. The
      Trustee may withhold from Holders notice of any continuing Default (except
      a
      Default in payment of principal or interest) if and so long as it determines
      that withholding notice is in their interests. The Company is required to file
      periodic certificates with the Trustee as to the Company’s compliance with the
      Indenture and knowledge or status of any Default.

     

    13.  TRUSTEE
      DEALINGS WITH THE COMPANY

     

    U.S.
      Bank, National Association, the initial Trustee under the Indenture, in its
      individual or any other capacity, may make loans to, accept deposits from and
      perform services for the Company or an Affiliate of the Company, and may
      otherwise deal with the Company or an Affiliate of the Company, as if it were
      not the Trustee.

     

    14.  NO
      RECOURSE AGAINST OTHERS

     

    A
      director, officer, employee or shareholder, as such, of the Company shall not
      have any liability for any obligations of the Company under the Securities
      or
      the Indenture nor for any claim based on, in respect of or by reason of such
      obligations or their creation. The Holder of this Security by accepting this
      Security waives and releases all such liability. The waiver and release are
      part
      of the consideration for the issuance of this Security.

     

    15.  AUTHENTICATION

     

    This
      Security shall not be valid until the Trustee or an authenticating agent
      manually signs the certificate of authentication on the other side of this
      Security.

    CERTIFICATE
      TO BE DELIVERED UPON EXCHANGE OR REGISTRATION

     

    OF
      TRANSFER OF RESTRICTED SECURITIES

     

    Re: 2.00%
      Convertible Senior Notes Due 2013 (the “Securities”) of Chattem,
      Inc.

     

    This
      certificate relates to $        
principal amount of Securities owned in (check applicable box) □
      book-entry or □
      definitive form by
                          
(the “Transferor”).

     

    The
      Transferor has requested a Registrar or the Trustee to exchange or register
      the
      transfer of such Securities.

     

    In
      connection with such request and in respect of each such Security, the
      Transferor does hereby certify that the Transferor is familiar with transfer
      restrictions relating to the Securities as provided in Section 2.12 of the
      Indenture dated as of November 22, 2006 between Chattem, Inc. and U.S.
      Bank, National Association, as trustee (the “Indenture”), and the transfer of
      such Security is being made pursuant to an effective registration statement
      under the Securities Act of 1933, as amended (the “Securities Act”), or the
      transfer or exchange, as the case may be, of such Security does not require
      registration under the Securities Act because (check applicable box):

     

     

    
      	
               

              
                

              

            	 	
              Such
                Security is being acquired for the Transferor’s own account, without
                transfer. 

            

    

    
      	 	 	 
	
               

              
                
 

            	 	
              Such
                Security is being transferred to the Company or a Subsidiary (as
                defined
                in the Indenture) of the Company. 

            
	 	 	 
	  	 	
              Such
                security is being transferred to a person the Transferor reasonably
                believes is a “qualified institutional buyer” (as defined in Rule 144A or
                any successor provision thereto (“Rule 144A”) under the Securities Act)
                that is purchasing for its own account or for the account of a “qualified
                institutional buyer”, in each case to whom notice has been given that the
                transfer is being made in reliance on such Rule 144A, and in each
                case in
                reliance on Rule 144A.

            
	 	 	 
	
               

              
                

              

            	 	
              Such
                Security is being transferred pursuant to and in compliance with
                an
                exemption from the registration requirements under the Securities
                Act in
                accordance with Rule 144 (or any successor thereto) (“Rule 144”) under the
                Securities Act.

            
	 	 	 
	 

              

            	 	Such
              Security is being transferred to a non-U.S. Person in an offshore
              transaction in compliance with Rule 904 of Regulation S under the
              Securities Act (or any successor thereto). 
	 	 	 
	
               

              
                
 

            	 	
              Such
                Security is being transferred pursuant to and in compliance with
                an
                exemption from the registration requirements of the Securities Act
                (other
                than an exemption referred to above) and as a result of which such
                Security will, upon such transfer, cease to be a “restricted security”
                within the meaning of Rule 144 under the Securities
                Act. 

            

    

     

    
      
        
        

      

      
        A-14

        
          

        

      

      
        
        

      

    

    The
      Transferor acknowledges and agrees that, if the transferee will hold any such
      Securities in the form of beneficial interests in a Global Note which is a
      “restricted security” within the meaning of Rule 144 under the Securities Act,
      then such transfer can only be made pursuant to (i) Rule 144A under the
      Securities Act and such transferee must be a “qualified institutional buyer” (as
      defined in Rule 144A) or (ii) Regulation S under the Securities
      Act.
