              The
                Company desires to make certain agreements with Employee in order
                to
                induce Employee to remain in such employ and in exchange for Employee’s

                parties desire to evidence their agreement as to the terms of the

      the parties hereby agree as follows:

    

    
      	1.  	
              Employment.
                The Company hereby continues its employment of Employee as the Company’s
                Vice President of Marketing and Business Development, and Employee
                hereby
                accepts such employment, subject to the provisions of this

      	2.  	
              Duties
                and Authority.
                Employee shall be employed as the Company’s Vice President of Marketing
                and Business Development. Employee shall have such duties and authority
                as
                are customary for the Vice President of Marketing and Business Development
                of a publicly held corporation with similar authority as the Company’s
                President may from time to time reasonably assign Employee consistent
                with
                the foregoing and the other provisions of this Agreement, but focusing

                the Company’s general product lines. Employee agrees to devote her entire
                business time, energy and skills to such employment. However, it
                is
                understood that Employee shall not be required to devote more than
                the
                usual and customary hours per calendar week to such employment as
                are
                generally expected of similarly situated employees of publicly held
                companies. At all times, Employee shall be subject to the direction
                of the
                Company’s Board of Directors and its
                President.

                Employee’s base salary shall be reviewed annually within 30 days prior to
                the end of each fiscal year (but such annual base salary shall not
                be
                reduced to less than the prior year’s annual base salary without
                Employee’s written consent).

                shall be entitled to paid vacations of not more than four weeks each
                calendar year, which may be taken at Employee’s discretion; provided,

      	(i)  	
              This
                Agreement may be terminated by the Company at any time for Cause
                (as

                compensation; provided, however, that if such voluntary termination
                occurs
                at any time after a change of control (as hereinafter defined), Employee
                shall be entitled to receive severance benefits for a period of 15

              Options.
                In
                the event of a Change in Control of the Company as that term is defined
                in
                the Agreement, stock options held by Employee shall become immediately
                exercisable without regard to vesting and/or applicable benchmarks

                the agreement governing the exercise of such options contains provisions
                expressly to the contrary. In the event of a sale or an exchange
                of assets
                or stock anticipated to constitute a Change in Control, the Company
                agrees
                that it shall make provisions for the conversion or exchange of shares
                to

      	(i)  	
              Important
                and essential assets of the Company’s business are the identity of the
                Company’s customers for its Products in the Protected Territory and the
                identity of relationships in its distribution network for its Products
                in
                the Protected Territory and their goodwill toward the Company relating
                to
                the marketing and distribution of the Company’s Products in the Protected
                Territory,

                in
                the Protected Territory, and the business and goodwill which the
                Company
                enjoys are dependent to a high degree upon their personal relationships
                with Employee; and

            

    

    

    
      	(iii)  	
              Selling
                and servicing the Company’s Products in the Protected Territory requires

                distribution network in the Protected Territory within 12 months
                immediately preceding such termination date (y) for the purpose of
                encouraging such persons to leave or terminate their relationship
                with the
                company, or (z) for the primary purpose of encouraging such members
                to

                entity.

                further agrees that the remedy at law for any breach for any of the
                provisions of this section will be inadequate and that the Company,
                its
                successors or assigns shall be entitled to injunctive relief in addition
                to any other rights or remedies which the Company may have for any
                such
                breach.

              Arbitration.
                Any controversy or claims arising out of or relating to this Agreement
                shall be submitted to binding arbitration in accordance with the
                Commercial Arbitration Rules of the American Arbitration Association
                in
                Waukesha County, Wisconsin, and judgment upon the award rendered
                by the
                arbitrator may be entered in any court having jurisdiction thereof.
                If the
                parties cannot agree on the choice of a single arbitrator within
                15 days
                after receipt of a notice of arbitration, then the parties shall
                contact
                the chairperson of the Alternative Dispute Resolution section of
                the
                Wisconsin Bar, who shall select an independent arbitrator, and the
                arbitration shall be decided by such independent arbitrator. Each
                of the
                parties reserves the right to file with a court of competent jurisdiction
                an application for temporary or preliminary injunctive relief or
                a
                temporary protective order on the grounds that the arbitration award
                to
                which the applicant may be entitled may be rendered ineffective in
                the
                absence of such relief. The arbitration award shall be in writing,
                and
                shall specify the factual and legal basis for the award. The losing
                party
                shall pay all costs and expenses of the arbitrator.

ARTICLE II.
  

 THE SECURITIES  

        Section 2.01    Form and Dating.    

        The
Securities and the Trustee's certificate of authentication shall be substantially in the form set forth in Exhibit A, which is incorporated in and forms a part of this
Indenture. The Securities may have notations, legends or endorsements as required by law, stock exchange rule or usage, provided such notations, legends
or endorsements are in form reasonably acceptable to the Company. Each Security shall be dated the date of its authentication. 

        The
Securities shall be issued initially in the form of one or more Global Securities, substantially in the form set forth in Exhibit A (the "Global
Security"), deposited with the Trustee, as custodian for the Depositary, registered in the name of the Depositary or a nominee thereof, duly executed by the Company and
authenticated by the Trustee as hereinafter provided and bearing the legend set forth in Exhibits B. The aggregate principal amount of the Global Security may from time to time be increased or
decreased by adjustments made on the records of the Trustee, as custodian for the Depositary, as hereinafter provided; provided, that in no event shall
the aggregate principal amount of the Global Security or Global Securities exceed $225,000,000 (or $258,750,000 if the Underwriters elect to purchase all of the Additional Securities pursuant to the
Option). 

        Securities
issued in exchange for interests in a Global Security pursuant to Section 2.15 may be issued in the form of permanent certificated Securities in registered form in
substantially the form set forth in Exhibit A (the "Physical Securities") and, if applicable, bearing any legends required by
Section 2.17. 

        Section 2.02
Execution and Authentication. 

        One
duly authorized Officer shall sign the Securities for the Company by manual or facsimile signature. 

        A
Security's validity shall not be affected by the failure of an Officer whose signature is on such Security to hold, at the time the Security is authenticated, the same office at the
Company. 

7

 

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

        Upon
a written order of the Company signed by one Officer of the Company, the Trustee shall authenticate Securities for original issue in the aggregate principal amount of $225,000,000
and such additional principal amount, if any, as shall be determined pursuant to the next sentence of this Section 2.02. Upon receipt by the Trustee of an Officer's Certificate stating that the
Underwriters have elected to purchase from the Company a specified principal amount of Additional Securities, not to exceed $33,750,000 pursuant to the Option, the Trustee shall authenticate and
deliver such specified principal amount of Additional Securities to or upon the written order of the Company signed as provided in the immediately preceding sentence. Such Officer's Certificate must
be received by the Trustee not later than the proposed date for delivering of such Additional Securities. The aggregate principal amount of Securities outstanding at any time may not exceed
$225,000,000 (or $258,750,000 if the Underwriters have elected to purchase all of the Additional Securities pursuant to the Option) except as provided in this Section 2.02. 

        If
a written order of the Company pursuant to this Section 2.02 has been, or simultaneously is, delivered, any instructions by the Company to the Trustee with respect to
endorsement, delivery or redelivery of a Security issued in global form shall be in writing but need not comply with Section 14.04 hereof and need not be accompanied by an Opinion of Counsel. 

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

        Section 2.03
Registrar, Paying Agent and Conversion Agent. 

        The
Company shall maintain, or shall cause to be maintained, (i) an office or agency in the Borough of Manhattan, The City of New York, where Securities may be presented for
registration of transfer or for exchange ("Registrar"), (ii) an office or agency in the Borough of Manhattan, The City of New York, where
Securities may be presented for payment ("Paying Agent") and (iii) an office or agency in the Borough of Manhattan, The City of New York, where
Securities may be presented for conversion ("Conversion Agent"). The Registrar shall keep a register of the Securities and of their transfer and
exchange. The Company may appoint or change one or more co-Registrars, one or more
additional paying agents and one or more additional conversion agents without notice and may act in any such capacity on its own behalf. The term "Registrar" includes any co-registrar; the
term "Paying Agent" includes any additional paying agent; and the term "Conversion Agent" includes any additional conversion agent. 

        The
Company shall enter into an appropriate agency agreement with any Agent not a party to this Indenture. The agreement shall implement the provisions of this Indenture that relate to
such Agent. The Company shall notify the Trustee of the name and address of any such Agent not a party to this Indenture. If the Company fails to maintain a Registrar, Paying Agent or Conversion
Agent, the Trustee shall act as such. 

        The
Company initially appoints the Trustee as Paying Agent, Registrar, Bid Solicitation Agent and Conversion Agent. 

        Section 2.04  Paying Agent to Hold Money in Trust. 

        Each
Paying Agent shall hold in trust for the benefit of the Securityholders or the Trustee all moneys held by the Paying Agent for the payment of the Securities, and shall notify the
Trustee of any Default by the Company in making any such payment. While any such Default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Company at
any time may require a Paying Agent to pay all money held by it to the Trustee and account for any funds so paid by 

8

 

it.
Upon payment over to the Trustee, the Paying Agent shall have no further liability for such money. If the Company acts as Paying Agent, it shall segregate and hold as a separate trust fund all
money held by it as Paying Agent. 

        Section 2.05
Securityholder Lists. 

        The
Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Securityholders. If the Trustee is not the
Registrar, the Company shall furnish, or shall cause to be furnished, 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 Securityholders appearing in the security register of the Registrar. 

        Section 2.06
Transfer and Exchange. 

        Subject
to Sections 2.15 and 2.16, if Securities are presented to the Registrar with a request to register their transfer or to exchange them for an equal principal amount of Securities
of other authorized denominations, the Registrar shall register the transfer or make the exchange if its requirements for such transaction are met. To permit registrations of transfer and exchanges,
the Trustee shall authenticate Securities at the Registrar's request or upon the Trustee's receipt of a Company Order therefor. The Company or the Trustee, as the case may be, shall not be required to
register the transfer of or exchange any Security (i) for a period of twenty (20) calendar days before selecting, pursuant to Section 3.03, Securities to be redeemed or
(ii) that has been selected for Redemption or for which a Purchase Notice has been delivered pursuant to Section 3.08 or 3.09, and not withdrawn, in accordance with this Indenture,
except, in the case of a partial redemption, purchase or repurchase, that portion of Securities not being redeemed or repurchased. 

        No
service charge shall be made for any transfer, exchange or conversion of Securities, but the Company or the Trustee may require payment of a sum sufficient to cover any transfer tax
or similar governmental charge that may be imposed in connection with any transfer, exchange or conversion of Securities, other than exchanges pursuant to Section 2.10, 9.05 or 10.02, or
Article III, not involving any transfer. 

        Section 2.07  Replacement Securities. 

        If
the Holder of a Security claims that the Security has been mutilated, lost, destroyed or wrongfully taken, the Company shall issue and the Trustee shall authenticate a replacement
Security upon surrender to the Trustee of the mutilated Security, or upon delivery to the Trustee of evidence of the loss, destruction or theft of the Security satisfactory to the Trustee and the
Company. In the case of a lost, destroyed or wrongfully taken Security, if required by the Trustee or the Company, an indemnity bond must be provided by the Holder that is reasonably satisfactory to
the Trustee and the Company to indemnify and hold harmless the Company and the Trustee from any loss which any of them may suffer if such Security is replaced. The Trustee and the Company may charge
such Holder for their expenses in replacing a Security. 

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

        Upon
the issuance of any new Securities under this Section 2.07, the Company may require the payment of a sum sufficient to cover any tax, assessment or other governmental charge
that may be imposed in relation thereto and any other reasonable expenses (including the reasonable fees and expenses of the Trustee or the Registrar) connected therewith. 

        Every
replacement Security is an additional obligation of the Company only as provided in Section 2.08. 

9

   
        Section 2.08 Outstanding Securities. 

        Securities
outstanding at any time are all the Securities authenticated by the Trustee except for those converted, those cancelled by it, those delivered to it for cancellation and those
described in this Section 2.08 as not outstanding. Except to the extent provided in Section 2.09, a Security does not cease to be outstanding because the Company or one of its
Subsidiaries or Affiliates holds the Security. 

        If
a Security is replaced pursuant to Section 2.07, it ceases to be outstanding unless the Trustee receives proof satisfactory to it, or a court holds, that the replaced Security
is held by a "protected purchaser," as that term is defined in the New York Uniform Commercial Code. 

        If
the Paying Agent (other than the Company) holds on an Option Purchase Date, Redemption Date, Fundamental Change Repurchase Date or Maturity Date, money sufficient to pay the aggregate
Option Purchase Price, Redemption Price, Fundamental Change Repurchase Price or principal amount, as the case may be, with respect to all Securities to be redeemed, purchased or paid upon Purchase at
Holder's Option, Redemption, Repurchase Upon Fundamental Change or maturity, as the case may be, then (unless there shall be a Default in the payment of such aggregate Option Purchase Price,
Redemption Price, Fundamental Change Repurchase Price or principal amount), except as otherwise provided herein, on and after such date such Securities shall be deemed to be no longer outstanding,
interest on such Securities shall cease to accrue, and such Securities shall be deemed paid whether or not such Securities are delivered to the Paying Agent. Thereafter, all rights of the Holders of
such Securities shall terminate with respect to such Securities, other than the right to receive the Option Purchase Price, Redemption Price, Fundamental Change Repurchase Price or principal amount,
as the case may be, in accordance with this Indenture. Notwithstanding the foregoing provisions of this paragraph, a Holder shall be entitled to convert a Security on or prior to the close of business
on the Business Day immediately preceding the Maturity Date, provided such Security has not been surrendered for payment upon maturity. 

        If
a Security is converted in accordance with Article X, then, from and after the time of such conversion on the Conversion Date, such Security shall cease to be outstanding, and
interest, if any, shall cease to accrue on such Security unless there shall be a Default in the payment or delivery of the consideration payable hereunder upon such conversion. 

        Section 2.09  Securities Held by the Company or an Affiliate. 

        In
determining whether the Holders of the required aggregate principal amount of Securities have concurred in any direction, waiver or consent, Securities owned by the Company or any of
its Subsidiaries or Affiliates shall be considered as though not outstanding, except that, for the purposes of determining whether a Responsible Officer of the Trustee shall be protected in relying on
any such direction, waiver or consent, only Securities which the Trustee knows are so owned shall be so disregarded. Securities so owned which have been pledged in good faith may be considered to be
outstanding for purposes of this Section 2.09 if the pledgee establishes, to the satisfaction of the Trustee the pledgee's right to concur with respect to such Securities and that the pledgee
is not, and is not acting at the direction or on behalf of, the Company, any other obligor on the Securities, an Affiliate of the Company or an affiliate of any such other obligor. In the event of a
dispute as to whether the pledgee has established the foregoing, the Trustee may rely on the advice of counsel or on an Officer's Certificate. 

        Section 2.10
Temporary Securities. 

        Until
definitive Securities are ready for delivery, the Company may prepare and the Trustee shall, upon receipt of a Company Order, authenticate temporary Securities. Temporary
Securities shall be substantially in the form of definitive Securities but may have variations that the Company considers appropriate for temporary Securities. Without unreasonable delay, the Company
shall prepare and the Trustee, upon receipt of a Company Order, shall authenticate definitive Securities in exchange for 

10

 

temporary
Securities. Until so exchanged, each temporary Security shall in all respects be entitled to the same benefits under this Indenture as definitive Securities, and such temporary Security
shall be exchangeable for definitive Securities in accordance with the terms of this Indenture. 

        Section 2.11  Purchase and Cancellation. 

        The
Company may, to the extent permitted by law, purchase Securities in the open market or by tender offer at any price or by private agreement. The Company may, at its option, and to
the extent permitted by law, reissue, resell or surrender to the Trustee for cancellation any Securities the Company purchases in this manner. Securities surrendered to the Trustee for cancellation
may not be reissued or resold and shall be promptly cancelled. 

        The
Company at any time may deliver Securities to the Trustee for cancellation. The Registrar, Paying Agent and Conversion Agent shall forward to the Trustee any Securities surrendered
to them for transfer, exchange, payment or conversion. The Trustee shall promptly cancel all Securities surrendered for transfer, exchange, payment, conversion or cancellation in accordance with its
customary procedures. The Company may not issue new Securities to replace Securities that it has paid or delivered to the Trustee for cancellation or that any Securityholder has converted pursuant to
Article X.
All cancelled Securities held by the Trustee shall be destroyed, and certification of their destruction shall be delivered by the Trustee to the Company unless the Company shall, by a Company Order,
direct that cancelled Securities be returned to it. 

        Any
Securities or shares of Common Stock issued upon the conversion of Securities that are purchased or owned by the Company or any Affiliate thereof may not be resold by the Company or
such Affiliate unless registered under the Securities Act or resold pursuant to an exemption from the registration requirements of the Securities Act in a transaction that results in such Securities
or shares of Common Stock, as the case may be, no longer being "restricted securities" (as defined under Rule 144 under the Securities Act). 

        Section 2.12  Defaulted Interest. 

        If
and to the extent the Company defaults in a payment of interest on the Securities, the Company shall pay in cash the defaulted interest in any lawful manner plus, to the extent not
prohibited by applicable statute or case law, interest on such defaulted interest at the rate provided in the Securities. The Company may pay the defaulted interest (plus interest on such defaulted
interest) to the persons who are Securityholders on a subsequent special record date. The Company shall fix such record date and payment date. At least fifteen (15) calendar days before the
record date, the Company shall mail to Securityholders a notice that states the record date, payment date and amount of interest to be paid. Upon the due payment in full, interest shall no longer
accrue on such defaulted interest pursuant to this Section 2.12. 

        Section 2.13
CUSIP Numbers. 

        The
Company in issuing the Securities may use one or more "CUSIP" numbers, and, if so, the Trustee shall use the CUSIP numbers in notices of redemption or exchange as a convenience to
Holders; provided, however, that no representation is hereby deemed to be made by the Trustee as to the correctness or accuracy of the CUSIP numbers
printed on the notice or on the Securities; provided further, that reliance may be placed only on the other identification numbers printed on the
Securities, and the effectiveness of any such notice shall not be affected by any defect in, or omission of, such CUSIP numbers. The Company shall promptly notify the Trustee of any change in the
CUSIP numbers. 

        Section 2.14
Deposit of Moneys. 

        Prior
to 11:00 A.M., New York City time, on each interest payment date, Maturity Date, Redemption Date, Option Purchase Date or Fundamental Change Repurchase Date, the Company
shall have deposited with a Paying Agent (or, if the Company is acting as its own Paying Agent, shall 

11

 

have
segregated and shall hold in trust in accordance with Section 2.04) money, in funds immediately available on such date, sufficient to make cash payments, if any, due on such interest
payment date, Maturity Date, Redemption Date, Option Purchase Date or Fundamental Change Repurchase Date, as the case may be, in a timely manner which permits the Paying Agent to remit payment to the
Holders on such interest payment date, Maturity Date, Redemption Date, Option Purchase Date or Fundamental Change Repurchase Date, as the case may be. 

        Section 2.15
Book-Entry Provisions for Global Securities. 

        (a)   The
Global Securities initially shall (i) be registered in the name of the Depositary or the nominee of the Depositary, (ii) be delivered to the Trustee as
custodian for the Depositary and (iii) bear legends as set forth in Section 2.17. 

        Members
of, or participants in, the Depositary ("Participants") shall have no rights under this Indenture with respect to any Global
Security held on their behalf by the Depositary, or the Trustee as its custodian, or under the Global Security, and the Depositary may be treated by the Company and the Trustee and any agent of the
Company and the Trustee as the absolute owner of the Global Security for all purposes whatsoever. Notwithstanding the foregoing provisions of this paragraph, nothing herein shall prevent the Company,
the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or impair, as between the Depositary
and Participants, the operation of customary practices governing the exercise of the rights of a Holder of any Security. 

        (b)   Transfers
of Global Securities shall be limited to transfers in whole, but not in part, to the Depositary, its successors or their respective nominees. In addition,
Physical Securities shall be transferred to all beneficial owners, as identified by the Depositary, in exchange for their beneficial interests in Global Securities only if (i) the Depositary
notifies the Company that the Depositary is unwilling or unable to continue as depositary for any Global Security (or the Depositary ceases to be a "clearing agency" registered under
Section 17A of the Exchange Act) and, in either case, a successor Depositary is not appointed by the Company within ninety (90) days of such notice or cessation or (ii) an Event
of Default has occurred and is continuing. 

        (c)   In
connection with the transfer of a Global Security in its entirety to beneficial owners pursuant to Section 2.15(b), such Global Security shall be deemed to be
surrendered to the Trustee for cancellation, and the Company shall execute, and the Trustee shall upon written instructions from the Company authenticate and deliver, to each beneficial owner
identified by the Depositary in exchange for its beneficial interest in such Global Security, an equal aggregate principal amount of Physical Securities of authorized denominations. 

        (d)   The
Holder of any Global Security may grant proxies and otherwise authorize any Person, including Participants and Persons that may hold interests through Participants,
to take any action which a Holder is entitled to take under this Indenture or the Securities. 

        Section 2.16
Special Transfer Provisions. 

        Notwithstanding
any other provisions of this Indenture, but except as provided in Section 2.15(b), a Global Security may not be transferred except as a whole by the Depositary to
a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of
such successor Depositary. 

        The
Registrar shall retain copies of all letters, notices and other written communications received pursuant to Section 2.15 or this Section 2.16 for the period required by
the TIA and the Exchange Act. The Company shall have the right to inspect and make copies of all such letters, notices or other 

12

 

written
communications at any reasonable time upon the giving of reasonable written notice to the Registrar. 

        Section 2.17
Restrictive Legends. 

        Each
Global Security shall bear the legend as set forth in Exhibit B. 

ARTICLE III.  

 REDEMPTION AND REPURCHASE  

        Redemption of the Securities, as permitted by any provision of this Indenture, shall be made: 

          (i)  with
respect to a repurchase at the Company's option, in accordance with Sections 3.01 to 3.07 (a "Redemption"); 

         (ii)  with
respect to a repurchase at the Holder's option, in accordance with Section 3.08 (a "Purchase at Holder's
Option"); and 

        (iii)  with
respect to any repurchase upon a Fundamental Change, in accordance with Section 3.09 (a "Repurchase Upon Fundamental
Change"). 

        The
Company shall comply with all federal and state securities laws, and the applicable laws of any foreign jurisdiction, in connection with any offer to sell or solicitations of offers
to buy Securities pursuant to this Article III, including, to the extent applicable, complying with the provisions of Rule 13e-4 and Regulation 14E under the Exchange
Act and filing a Schedule TO or any other required schedule under the Exchange Act or other applicable laws. 

        Section 3.01
Right of Redemption. 

        The
Company shall have the right, at the Company's option, at any time, and from time to time, on a Redemption Date on or after November 15, 2011, to redeem all or any part of the
Securities at a price payable in cash equal to the Redemption Price; provided, however, that in no event shall any Redemption Date be a Legal Holiday;  provided,
further, that if the Redemption Date with respect to a Security is after the close of business on a record date for the payment of an
installment of interest and on or before the related interest payment date, then accrued and unpaid interest to, but excluding, such interest payment date shall be paid, on such interest payment date,
to the Holder of record of such Security (without any surrender of such Security by such Holder) at the close of business on such record date, the Redemption Price shall be equal to the principal
amount of Securities subject to Redemption and the Holder surrendering such Security for Redemption shall not be entitled to any interest (unless such Holder was also the Holder of record of such
Security at the close of business on such record date); provided, further, that the Company shall make at least 10 semi-annual interest
payments (including the interest payments on May 15, 2007 and November 15, 2011) in the full amount required by this Indenture with respect to the Securities prior to redeeming any
Securities pursuant to this Section 3.01. 

        Securities
in denominations larger than $1,000 principal amount may be redeemed in part but only in integral multiples of $1,000 principal amount. 

        Section 3.02
Notices to Trustee. 

        If
the Company elects to redeem Securities pursuant to Section 3.01, it shall notify the Trustee of the Redemption Date, the applicable provision of this Indenture pursuant to
which the Redemption is to be made and the aggregate principal amount of Securities to be redeemed, which notice shall be provided to the Trustee by the Company at least fifteen (15) days prior
to the mailing, in accordance with Section 3.04, of the notice of Redemption (unless a shorter notice period shall be satisfactory to the Trustee). 

13

 

        Section 3.03
Selection of Securities to be Redeemed. 

        If
the Company has elected to redeem less than all the Securities pursuant to Section 3.01, the Trustee shall, within five (5) Business Days after receiving the notice
specified in Section 3.02, select the Securities to be redeemed by lot, on a pro rata basis or in accordance with any other method the Trustee
considers fair and appropriate (and in such manner as complies with applicable legal requirements). The Trustee shall make such selection from Securities then outstanding and not already to be
redeemed by virtue of having been previously called for Redemption. The Trustee may select for Redemption portions of the principal amount of Securities that have denominations larger than $1,000
principal amount. Securities and portions of them the Trustee selects for Redemption shall be in amounts of $1,000 principal amount or integral multiples of $1,000 principal amount. The Trustee shall
promptly notify the Company in writing of the Securities selected for Redemption and the principal amount thereof to be redeemed. 

        The
Registrar need not register the transfer of or exchange any Securities that have been selected for Redemption, except the unredeemed portion of the Securities being redeemed in part. 

        Section 3.04
Notice of Redemption. 

        At
least thirty (30) days but not more than sixty (60) days before a Redemption Date, the Company shall mail, or cause to be mailed, by first-class mail a notice of
Redemption to each Holder whose Securities are to be redeemed, at the address of such Holder appearing in the security register. 

        The
notice shall identify the Securities and the aggregate principal amount thereof to be redeemed pursuant to the Redemption and shall state: 

          (i)  the
Redemption Date; 

         (ii)  the
Redemption Price; 

        (iii)  the
Conversion Rate and the Conversion Price; 

        (iv)  the
names and addresses of the Paying Agent and the Conversion Agent; 

         (v)  that
the right to convert the Securities called for Redemption will terminate at the close of business on the Business Day immediately preceding the Redemption Date,
unless there shall be a Default in the payment of the Redemption Price payable as provided in this Indenture upon Redemption; 

        (vi)  that
Holders who want to convert Securities must satisfy the requirements of Article X; 

       (vii)  that
Securities called for Redemption must be surrendered to the Paying Agent to collect the Redemption Price payable as herein provided upon Redemption; 

      (viii)  that,
unless there shall be a Default in the payment of the Redemption Price payable as herein provided upon Redemption (including, where the Redemption Date is after
a record date for the payment of an installment of interest and on or before the related interest payment date, the payment, on such interest payment date, of accrued and unpaid interest to, but
excluding, such interest payment date to the Holder of record at the close of business on such record date), interest on Securities called for Redemption ceases to accrue on and after the Redemption
Date, except as otherwise provided herein, and all rights of the Holders of such Securities shall terminate on and after the Redemption Date, other than the right to receive, upon surrender of such
Securities and in accordance with this Indenture, the amounts due hereunder on such Securities upon Redemption (and the rights of the Holder(s) of record of such Securities to receive, on the
applicable interest payment date, accrued and unpaid interest in accordance herewith in the event the Redemption Date is after a record date for the payment of an installment of interest and on or
before the related interest payment date); and 

14

 

        (ix)  the
CUSIP number or numbers, as the case may be, of the Securities. 

        The
right, pursuant to Article X, to convert Securities called for Redemption shall terminate at the close of business on the Business Day immediately preceding the Redemption
Date, unless there shall be a Default in the payment of the Redemption Price payable as herein provided upon Redemption. 

        At
the Company's request, upon reasonable prior notice, the Trustee shall mail the notice of Redemption in the Company's name and at the Company's expense;  provided, however, that the form and content of
such notice shall be prepared by the Company. 

        Section 3.05
Effect of Notice of Redemption. 

        Once
notice of Redemption is mailed, Securities called for Redemption become due and payable on the Redemption Date at the specified Redemption Price and, on and after such Redemption
Date (unless there shall be a Default in the payment of such Redemption Price), except as otherwise provided herein, such Securities shall cease to bear interest, and all rights of the Holders of such
Securities shall terminate, other than the right to receive such Redemption Price upon surrender of such Securities to the Paying Agent. 

        If
any Security shall not be fully and duly paid in accordance herewith upon Redemption, the Redemption Price shall, until paid, bear interest at the rate borne by such Security on the
principal amount of such Security, and such Security shall continue to be convertible pursuant to Article X. 

        Notwithstanding
anything herein to the contrary, no Securities may be redeemed by the Company if the principal amount of the Securities has been accelerated (other than as a result of a
failure to pay the relevant Redemption Price), and such acceleration has not been rescinded, on or prior to the relevant Redemption Date. The Paying Agent will promptly return to the respective
Holders thereof any Securities held by it during the continuance of such an acceleration. 

        Section 3.06
Deposit of Redemption Price. 

        Prior
to 11:00 A.M., New York City time on the Redemption Date, the Company shall deposit with a Paying Agent (or, if the Company is acting as its own Paying Agent, shall have
segregated and shall hold in trust in accordance with Section 2.04) money, in funds immediately available on the Redemption Date, sufficient to pay the consideration payable as herein provided
upon Redemption with respect to all Securities to be redeemed on that date. The Paying Agent shall return to the Company, as soon as practicable, any money not required for that purpose. 

        Section 3.07
Securities Redeemed in Part. 

        Any
Security to be submitted for Redemption only in part shall be delivered pursuant to Section 3.05 (with, if the Company or the Trustee so requires, due endorsement by, or a
written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by the Holder thereof or its attorney duly authorized in writing with a medallion guarantee), and the
Company shall execute, and the Trustee shall authenticate and make available for delivery to the Holder of such Security without service charge, a new Security or Securities, of any authorized
denomination(s) as requested by such Holder, of the same tenor and in aggregate principal amount equal to the portion of such Security not submitted for Redemption. 

        If
any Security selected for partial Redemption is converted in part, the principal of such Security subject to Redemption shall be reduced by the principal amount of such Security that
is converted. 

        Section 3.08  Purchase of Securities at Option of the Holder. 

        (a)   At
the option of the Holder thereof, Securities (or portions thereof that are integral multiples of $1,000 in principal amount) shall be purchased by the Company
pursuant to this Section 3.08 on November 15, 2011, November 15, 2016 and November 15, 2021 (each, an "Option Purchase
Date"), at 

15

 

a
purchase price, payable in cash, equal to one hundred percent (100%) of the principal amount of the Securities (or such portions thereof) to be so purchased, plus accrued and unpaid interest, if
any, to, but excluding, the applicable Option Purchase Date (the "Option Purchase Price") (provided,
that if such Option Purchase Date is after the close of business on a record date for the payment of an installment of interest and on or before the related interest payment date, then accrued and
unpaid interest to, but excluding, such interest payment date shall be paid, on such interest payment date, to the Holder of record of such Securities (without any surrender of such Securities by such
Holder) at the close of business on such record date, the Option Purchase Price shall be equal to the principal amount of Securities subject to Purchase at Holder's Option and the Holder surrendering
such Security for repurchase shall not be entitled to any interest (unless such Holder was also the Holder of record of such Security at the close of business on such record date)), upon: 

          (i)  delivery
to the Company (if it is acting as its own Paying Agent), or to a Paying Agent designated by the Company for such purpose in the Option Purchase Notice, by
such Holder, at any time from the opening of business on the date that is twenty (20) Business Days prior to the applicable Option Purchase Date until the close of business on the Business Day
immediately preceding the applicable Option Purchase Date, of a Purchase Notice, in the form set forth in the Securities or any other form of written notice substantially similar thereto, in each
case, duly completed and signed, with appropriate signature guarantee, stating: 

        (A)  the
certificate number(s) of the Securities which the Holder will deliver to be purchased, if such Securities are Physical Securities; 

        (B)  the
principal amount of Securities to be purchased, which must be $1,000 or an integral multiple thereof; and 

        (C)  that
such principal amount of Securities are to be purchased as of the applicable Option Purchase Date pursuant to the terms and conditions specified in
Section 3.08 of this Indenture; and 

         (ii)  delivery
to the Company (if it is acting as its own Paying Agent), or to a Paying Agent designated by the Company for such purpose in the Option Purchase Notice, at any
time after delivery of such Purchase Notice, of such Securities (together with all necessary endorsements), such delivery being a condition to receipt by the Holder of the Option Purchase Price
therefor payable as herein provided upon Purchase at Holder's Option (provided, however, that the Holder of record of such Securities on the record date
immediately preceding such Option Purchase Date need not surrender such Securities
in order to be entitled to receive, on the relevant interest payment date, the accrued and unpaid interest due thereon). 

        If
such Securities are held in book-entry form through the Depositary, the Purchase Notice shall comply with applicable procedures of the Depositary. 

        Upon
delivery of Physical Securities to the Company (if it is acting as its own Paying Agent) or such Paying Agent, such Holder shall be entitled to receive, upon request, from the
Company or such Paying Agent, as the case may be, a nontransferable receipt of deposit evidencing such delivery. 

        Notwithstanding
anything herein to the contrary, any Holder that has delivered the Purchase Notice contemplated by this Section 3.08(a) to the Company (if it is acting as its own
Paying Agent) or to a Paying Agent designated by the Company for such purpose in the Option Purchase Notice shall have the right to withdraw such Purchase Notice by delivery, at any time prior to the
close of business on the Business Day immediately preceding the applicable Option Purchase Date, of a written notice of withdrawal to the Company (if acting as its own Paying Agent) or the Paying
Agent, which notice shall contain the information specified in Section 3.08(b)(viii). 

16

   
        The Paying Agent shall promptly notify the Company of the receipt by it of any Purchase Notice or written notice of withdrawal thereof. 

        (b)   The
Company shall give notice (the "Option Purchase Notice") on a date not less than twenty (20) Business Days
prior to each Option Purchase Date to each Holder at its address shown in the register of the Registrar and to each beneficial owner as required by applicable law. Such notice shall state: 

          (i)  the
Option Purchase Price and the Conversion Rate; 

         (ii)  the
Conversion Rate then applicable to the Securities; 

        (iii)  the
names and addresses of the Paying Agent and the Conversion Agent; 

        (iv)  that
Securities with respect to which a Purchase Notice is given by a Holder may be converted pursuant to Article X only if such Purchase Notice has been
withdrawn in accordance with this Section 3.08 or if there shall be a Default in the payment of such Option Purchase Price payable as herein provided upon Purchase at Holder's Option; 

         (v)  that
Securities (together with any necessary endorsements) must be surrendered to the Paying Agent to collect payment of the Option Purchase Price payable as herein
provided upon Purchase at Holder's Option; 

        (vi)  that
the Option Purchase Price for any Security as to which a Purchase Notice has been given and not withdrawn will be paid as promptly as practicable, but in no event
later than the later of such Option Purchase Date or the time of delivery of the Security as described in clause (v) above; 

       (vii)  the
procedures the Holder must follow to exercise rights under this Section 3.08 (including the name and address of the Paying Agent) and a brief description of
those rights; 

      (viii)  that
a Holder will be entitled to withdraw its election in the Purchase Notice if the Company (if acting as its own Paying Agent) or the Paying Agent receives, at any
time prior to the close of business on the Business Day immediately preceding the applicable Option Purchase Date, or such longer period as may be required by law, a letter, telegram or facsimile
transmission (with confirmation of good transmission thereof) setting forth (I) the name of such Holder, (II) a statement that such Holder is withdrawing its election to have Securities
purchased by the Company on such Option Purchase Date pursuant to a Purchase at Holder's Option, (III) the certificate number(s) of such Securities to be so withdrawn, if such Securities are
Physical Securities, (IV) the principal amount of the Securities of such Holder to be so withdrawn, which amount must be $1,000 or an integral multiple thereof and (V) the principal
amount, if any, of the Securities of such Holder that remain subject to the Purchase Notice delivered by such Holder in accordance with this Section 3.08, which amount must be $1,000 or an
integral multiple thereof; 

        (ix)  that
on and after the applicable Option Purchase Date (unless there shall be a Default in the payment of the Option Purchase Price as herein provided upon a Purchase at
Holder's Option), interest on Securities subject to Purchase at Holder's Option will cease to accrue, and all rights of the Holders of such Securities shall terminate, other than the right to receive,
in accordance herewith, the Option Purchase Price payable as herein provided upon a Purchase at Holder's Option; and 

         (x)  the
CUSIP number or numbers, as the case may be, of the Securities. 

        At
the Company's request, upon reasonable prior notice, the Trustee shall mail such Option Purchase Notice in the Company's name and at the Company's expense;  provided, however, that the form and content
of such Option Purchase Notice shall be prepared by the Company. 

17

 

        No
failure of the Company to give an Option Purchase Notice shall limit any Holder's right pursuant hereto to exercise its rights to require the Company to purchase such Holder's
Securities pursuant to a Purchase at Holder's Option. 

        (c)   Subject
to the provisions of this Section 3.08, the Company shall pay, or cause to be paid, the Option Purchase Price with respect to each Security subject to
Purchase at Holder's Option to the Holder thereof as promptly as practicable, but in no event later than the later of the applicable Option Purchase Date and the time such Security (together with all
necessary endorsements) is surrendered to the Paying Agent. 

        (d)   Prior
to 11:00 A.M., New York City time on the applicable Option Purchase Date, the Company shall deposit with a Paying Agent (or, if the Company is acting as its
own Paying Agent, shall have segregated and shall hold in trust in accordance with Section 2.04) money, in funds immediately available on the applicable Option Purchase Date, sufficient to pay
the Option Purchase Price with respect to all of the Securities that are to be purchased by the Company on such Option Purchase Date pursuant to a Purchase at Holder's Option. The Paying Agent shall
return to the Company, as soon as practicable, any money not required for that purpose. 

        (e)   Once
the Purchase Notice has been duly delivered in accordance with this Section 3.08, the Securities to be purchased pursuant to the Purchase at Holder's Option
shall, on the applicable Option Purchase Date, become due and payable in accordance herewith, and, on and after such date (unless there shall be a Default in the payment of the Option Purchase Price
payable as herein provided upon a Purchase at Holder's Option), such Securities shall cease to bear interest, and all rights of the Holders of such Securities shall terminate, other than the right to
receive, in accordance herewith, the Option Purchase Price. 

        (f)    Securities
with respect to which a Purchase Notice has been duly delivered in accordance with this Section 3.08 may be converted pursuant to Article X, if
otherwise convertible in accordance with Article X, only if such Purchase Notice has been withdrawn in accordance with this Section 3.08 or if there shall be a Default in the payment of
the Option Purchase Price payable as herein provided upon a Purchase at Holder's Option. 

        (g)   If
any Security subject to Purchase at Holder's Option shall not be paid in accordance herewith, the principal of, and accrued and unpaid interest on, such Security
shall, until paid, bear interest, payable in cash, at the rate borne by such Security on the principal amount of such Security, and if such Security is otherwise convertible pursuant to
Article X, it shall continue to be convertible pursuant to Article X. 

        (h)   Any
Security which is to be submitted for Purchase at Holder's Option only in part shall be delivered pursuant to this Section 3.08 (with, if the Company or the
Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or its attorney duly authorized in
writing, with a medallion guarantee), and the Company shall execute, and the Trustee shall authenticate and make available for delivery to the Holder of such Security without service charge, a new
Security or Securities, of any authorized denomination as requested by such Holder, of the same tenor and in aggregate principal amount equal to the portion of such Security not submitted for Purchase
at Holder's Option. 

        (i)    Notwithstanding
anything herein to the contrary, no Securities may be purchased by the Company on an Option Purchase Date if the principal amount of the Securities has
been accelerated (other than as a result of a failure to pay the relevant Option Purchase Price), and such acceleration has not been rescinded, on or prior to the relevant Option Purchase Date. The
Paying Agent will promptly return to the respective Holders thereof any Securities held by it during the continuance of such an acceleration.

excluding, the Fundamental Change Repurchase Date (the "Fundamental Change Repurchase Price") (provided,
that if such Fundamental Change Repurchase Date is after the close of business on a record date for the payment of an installment of interest and on or before the related interest payment date, then
the accrued and unpaid interest, if any, to, but excluding, such interest payment date shall be paid, on such interest payment date, to the Holder of record of such Securities at the close of business
on such record date (without any surrender of such Securities by such Holder), the Fundamental Change Repurchase Price shall be equal to the principal amount of Securities subject to Repurchase Upon
Fundamental Change and the Holder surrendering such Securities for repurchase shall not be entitled to any such accrued and unpaid interest unless such Holder was also the Holder of record of such
Securities at the close of business on such record date), upon:

terminate, other than the right to receive, in accordance herewith, the Fundamental Change Repurchase Price payable as herein provided upon Repurchase Upon Fundamental Change; 

        (xi)  that
a Holder will be entitled to withdraw its election in the Purchase Notice if the Company (if acting as its own Paying Agent), or the Paying Agent receives, prior

CUSIP number or numbers, as the case may be, of the Securities. 

        At
the Company's request, upon reasonable prior notice, the Trustee shall mail such Fundamental Change Notice in the Company's name and at the Company's expense;  provided, however, that the form and
content of such Fundamental Change Notice shall be prepared by the Company. 

        No
failure of the Company to give a Fundamental Change Notice shall limit any Holder's right pursuant hereto to exercise a Fundamental Change Repurchase Right. 

        (c)   Subject
to the provisions of this Section 3.09, the Company shall pay, or cause to be paid, the Fundamental Change Repurchase Price with respect to each Security
as to which the Fundamental Change Repurchase Right shall have been exercised to the Holder thereof as promptly as practicable, but in no event later than the later of the Fundamental Change
Repurchase Date and the time such Security (together with all necessary endorsements) is surrendered to the Paying Agent. 

        (d)   Prior
to 11:00 A.M., New York City time on a Fundamental Change Repurchase Date, the Company shall deposit with a Paying Agent (or, if the Company is acting as
its own Paying Agent, shall have segregated and shall hold in trust in accordance with Section 2.04) money, in funds immediately available on the Fundamental Change Repurchase Date, sufficient

the Fundamental Change Notice and the Purchase Notice have been duly given in accordance with this Section 3.09, the Securities to be repurchased pursuant to
a Repurchase Upon Fundamental Change shall, on the Fundamental Change Repurchase Date, become due and payable in accordance herewith, and, on and after such date (unless there shall be a Default in
the payment of the Fundamental Change Repurchase Price payable as herein provided upon Repurchase Upon Fundamental Change), such Securities shall cease to bear interest, and all rights of the Holders
of such Securities shall terminate, other than the right to receive, in accordance herewith, the Fundamental Change Repurchase Price. 

        (f)    Securities
with respect to which a Purchase Notice has been duly delivered in accordance with this Section 3.09 may be converted pursuant to Article X, if
otherwise convertible in accordance with Article X, only if such Purchase Notice has been withdrawn in accordance with this Section 3.09 or if 

21

 

there
shall be a Default in the payment of the Fundamental Change Repurchase Price payable as herein provided upon Repurchase Upon Fundamental Change. 

        (g)   If
any Security shall not be paid upon surrender thereof for Repurchase Upon Fundamental Change, the principal of, and accrued and unpaid interest on, such Security
shall, until paid, bear interest, payable in cash, at the rate borne by such Security on the principal amount of such Security, and if such Security is otherwise convertible pursuant to
Article X, it shall continue to be convertible pursuant to Article X. 

        (h)   Any
Security which is to be submitted for Repurchase Upon Fundamental Change only in part shall be delivered pursuant to this Section 3.09 (with, if the Company

authorized in writing, with a medallion guarantee), and the Company shall execute, and the Trustee shall authenticate and make available for delivery to the Holder of such Security without service
charge, a new Security or Securities, of any authorized denomination as requested by such Holder, of the same tenor and in aggregate principal amount equal to the portion of such Security not duly
submitted for Repurchase Upon Fundamental Change. 

        (i)    Notwithstanding
anything herein to the contrary, no Securities may be purchased by the Company on a Fundamental Change Repurchase Date if the principal amount of the
Securities has been accelerated (other than as a result of a failure to pay the relevant Fundamental Change Repurchase Price), and such acceleration has not been rescinded, on or prior to the relevant
Fundamental Change Repurchase Date. The Paying Agent will promptly return to the respective Holders thereof any Securities held by it during the continuance of such an acceleration. 

        (j)    As
used herein and in the Securities, a "Fundamental Change" shall be deemed to have occurred upon the occurrence of
either a "Change in Control" or a "Termination of Trading." 

        (i)    A
"Change in Control" shall be deemed to have occurred at such time as: 

        (A)  any
"person" or "group" (as such terms are used in Sections 13(d) and 14(d) of the Exchange Act) is or becomes the "beneficial owner" (as such term is used in
Rule 13d-3 under the Exchange Act), directly or indirectly, of fifty percent (50%) or more of the total outstanding voting power of the Company's Voting Stock (such an event, an
"Acquisition of Voting Control"); or 

        (B)  there
occurs a sale, transfer, lease, conveyance or other disposition of all or substantially all of the property or assets of the Company to any "person" or "group" (as
such terms are used in Sections 13(d) and 14(d) of the Exchange Act), including any group acting for the purpose of acquiring, holding, voting or disposing of securities within the meaning of
Rule 13d-5(b)(1) under the Exchange Act; or 

        (C)  the
Company consolidates with, or merges with or into, another person or any person consolidates with, or merges with or into, the Company, unless either: 

         (1)  the
persons that "beneficially owned" (as such term is used in Rule 13d-3 under the Exchange Act), directly or indirectly, the shares of the Company's
Voting Stock immediately prior to such consolidation or merger "beneficially own," directly or indirectly, immediately after such consolidation or merger, shares of the surviving or continuing
corporation's Voting Stock representing at least a majority of the total outstanding voting power of the Voting Stock of the surviving or continuing corporation in substantially the same proportion as
such ownership immediately prior to such consolidation or merger; or 

22

 

         (2)  both
of the following conditions are satisfied (a transaction that satisfies both of the conditions set forth in this clause (2), a
"Listed Stock Business Combination"): (x) at least ninety percent (90%) of the consideration (other than cash payments for fractional shares or
pursuant to statutory appraisal rights) in such consolidation or merger consists of common stock and any associated rights traded or quoted on a U.S. national securities exchange (or which will be so
traded or quoted when issued or exchanged in connection with such consolidation or merger), and, (y) as a result of such consolidation or merger, the Securities become convertible into cash and
the Daily Share Amount, if any, which shall be payable at the Company's option in cash, shares of such common stock and associated rights or a combination thereof; or 

        (D)  the
following persons cease for any reason to constitute a majority of the Board of Directors: 

         (1)  individuals
who on the Issue Date constituted the Board of Directors; and 

         (2)  any
new directors whose election to the Board of Directors or whose nomination for election by the Company's shareholders was approved by at least a majority of the
directors of the Company then still in office who either were directors of the Company whose election or nomination for election was previously so approved or were directors of the Company on the
Issue Date; or 

        (E)  the
Company is liquidated or dissolved or the holders of the Company's Capital Stock approve any plan or proposal for the liquidation or dissolution of the Company. 

        (ii)   A
"Termination of Trading" shall be deemed to occur if the Common Stock (or other common stock into which the Securities
are then convertible) is neither listed for trading on a U.S. national securities exchange nor approved for trading on an established automated over-the-counter trading market
in the United States.

        The
Company shall pay all amounts due with respect to the Securities on the dates and in the manner provided in the Securities and this Indenture. All such amounts shall be considered
paid on the date due if the Paying Agent holds (or, if the Company is acting as Paying Agent, the Company has segregated and holds in trust in accordance with Section 2.04) on that date money
sufficient to pay the amount then due with respect to the Securities (unless there shall be a Default in the payment of such amounts to the respective Holder(s)). The Company will pay, in money of the
United States that at the time of payment is legal tender for payment of public and private debts, all amounts due in cash with respect to the Securities, which amounts shall be paid (A) in the
case of a Global Security, by wire transfer of immediately available funds to the account designated by the Depositary or its nominee; (B) in the case of a Physical Security that is held by a
Holder of more than five million dollars ($5,000,000) in aggregate principal amount of Securities, by wire transfer of immediately available funds to the account specified by such Holder or, if such
Holder does not specify an account, by mailing a check to the address of such Holder set forth in the register of the Registrar; and (C) in the case of a Physical Security that is held by a
Holder of five million dollars ($5,000,000) or less in aggregate principal amount of Securities, by mailing a check to the address of such Holder set forth in the register of the Registrar.

the Trustee, Registrar or co-Registrar) where Securities may be surrendered for registration of transfer or exchange, payment or conversion. The Company will give prompt written notice to
the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain, or fail to cause to maintain, any such required office or
agency or shall fail to furnish the Trustee with the address thereof, such presentations and surrenders may be made or served at the applicable Corporate Trust Office of the Trustee. The Company shall
maintain, or cause to be maintained, in the Borough of Manhattan, the City of New York, an office or agency where notices and demands to or upon the Company in respect of the Securities and this
Indenture may be served, provided that such office or agency may instead be at the principal office of the Company located in the United States. 

        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 in the Borough of Manhattan, the City of New York for such purposes. The Company shall give prompt written notice to the Trustee of any such designation or rescission
and of any change in the location of any such other office or agency. 

        The
Company hereby designates the Corporate Trust Office of the Trustee as an agency of the Company in accordance with Section 2.03. 

        Section 4.03

be, required to file with the SEC the Company's annual report (whether on Form 10-K under the Exchange Act or another appropriate form) for such fiscal year, a certificate of two
(2) or more Officers, in the form required by Section 14.05 stating whether or not the signatories to such certificate have actual knowledge of any Default or Event of Default by the
Company in performing any of its obligations under this Indenture or the Securities. If such signatories do know of any such Default or Event of Default, then such certificate shall describe the
Default or Event of Default and its status. 

        Section 4.05
Stay, Extension and Usury Laws. 

        The
Company covenants (to the extent that it may lawfully do so) that it will 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 wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Company (in each case, to the
extent that 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 has been enacted.

existence of each of its Subsidiaries, in accordance with the respective organizational documents of the Company and of each Subsidiary, and the rights (charter and statutory), licenses and franchises
of the Company and its Subsidiaries; provided, however, that the Company shall not be required to preserve any such right, license or franchise, or the
corporate existence of any Subsidiary, if in the good faith judgment of the Board of Directors (i) such preservation or existence is not material to the conduct of business of the Company and
(ii) the loss of such right, license or franchise or the dissolution of such Subsidiary does not have a material adverse impact on the Holders. 

        Section 4.07
Notice of Default. 

        Upon
the Company becoming aware of the occurrence of any Default or Event of Default, the Company shall give prompt written notice of such Default or Event of Default, and any remedial
action proposed to be taken, to the Trustee. 

        Section 4.08
Further Instruments And Acts.

request of the Trustee, the Company shall execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more

 DEFAULTS AND REMEDIES  

        Section 6.01 Events of Default. 

        An
"Event of Default" occurs if:

any of its Subsidiaries for money borrowed in such aggregate principal amount or more so that it becomes due and payable prior to the date on which it would otherwise become due and payable and such
default is not cured or waived, or such acceleration is not rescinded, within sixty (60) days after written notice to the Company by the Trustee or to the Company and the Trustee by Holders of
at least twenty five percent (25%) in the aggregate principal amount of the Securities then outstanding, each in accordance with this Indenture; 

      (viii)  the
Company or any of its Subsidiaries fails, within sixty (60) days, to pay, bond or otherwise discharge any judgments or orders for the payment of money the

        (ix)  the
Company or any of its Significant Subsidiaries or any group of Subsidiaries of the Company that in the aggregate would constitute a Significant Subsidiary of the
Company, pursuant 

26

 

to,
or within the meaning of, any Bankruptcy Law, insolvency law, or other similar law now or hereafter in effect or otherwise, either: 

        (A)  commences
a voluntary case, 

        (B)  consents
to the entry of an order for relief against it in an involuntary case, 

        (C)  consents

Significant Subsidiary of the Company insolvent or bankrupt, 

        (B)  appoints

        (C)  orders

and,
in the case of each of the foregoing clauses (A), (B) and (C) of this Section 6.01(x), the order or decree remains unstayed and in effect for at least thirty
(30) consecutive days. 

        The
term "Bankruptcy Law" means Title 11, U.S. Code or any similar U.S. Federal or State law for the relief of debtors. The term
"Custodian" means any receiver, trustee, assignee, liquidator or similar official under any Bankruptcy Law. 

        A
Default under clause (v) above is not an Event of Default until (I) the Trustee notifies the Company, or the Holders of at least twenty five percent (25%) in aggregate
principal amount of the Securities then outstanding notify the Company and the Trustee in writing, of the Default and (II) the Default is not cured within ninety (90) days after receipt
of such notice. Such notice must specify the Default,
demand that it be remedied and state that the notice is a "Notice of Default." If the Holders of at least twenty five percent (25%) in aggregate
principal amount of the outstanding Securities request the Trustee to give such notice on their behalf, the Trustee shall do so. When a Default is cured, it ceases to exist for all purposes under this
Indenture. 

        Section 6.02
Acceleration. 

        If
an Event of Default (excluding an Event of Default specified in Section 6.01(ix) or (x) with respect to the Company (but including an Event of Default specified
in Section 6.01(ix) or (x) solely with respect to a Significant Subsidiary of the Company or any group of Subsidiaries of the Company that in the aggregate would constitute a
Significant Subsidiary of the Company)) occurs and is continuing, the Trustee by notice to the Company, or the Holders of at least twenty five percent (25%) in aggregate principal amount of the
Securities then outstanding by notice to the Company and the Trustee, may declare the Securities to be immediately due and payable in full. Upon such declaration, the principal of, and any accrued and
unpaid interest on, all Securities shall be due and payable 

27

 

immediately.
If an Event of Default specified in Section 6.01(ix) or (x) with respect to the Company (excluding, for purposes of this sentence, an Event of Default specified in
Section 6.01(ix) or (x) solely with respect to a Significant Subsidiary of the Company or any group of Subsidiaries of the Company that in the aggregate would constitute a
Significant Subsidiary of the Company) occurs, the principal of, and accrued and unpaid interest on, all the Securities shall ipso facto become and be
immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. The Holders of a majority in aggregate principal amount of the Securities then outstanding by
written notice to the Trustee may rescind or annul an acceleration and its consequences if (A) the rescission would not conflict with any order or decree, (B) all existing Events of
Default, except the nonpayment of principal or interest that has become due solely because of the acceleration, have been cured or waived and (C) all amounts due to the Trustee under
Section 7.07 have been paid. 

        Section 6.03
Other Remedies. 

        Notwithstanding
any other provision of this Indenture, if an Event of Default occurs and is continuing, and a Responsible Officer of the Trustee has actual knowledge of such Event of
Default, the Trustee may pursue any available remedy by proceeding at law or in equity to collect the payment of amounts due with respect to the Securities or to enforce the performance of any
provision of the Securities or this Indenture. 

        The
Trustee may maintain a proceeding even if it does not possess any of the Securities or does not produce any of them in the proceeding. A delay or omission by the Trustee or any
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. All remedies are
cumulative. 

        Section 6.04
Waiver of Past Defaults. 

        Subject
to Sections 6.07 and 9.02, the Holders of a majority in aggregate principal amount of the Securities then outstanding may, by notice to the Trustee, waive any past Default or
Event of Default and its consequences, other than (A) a Default or Event of Default in the payment of the principal of, or premium, if any, or interest on any Security, or in the payment of the
Redemption Price, the Option Purchase Price or the Fundamental Change Repurchase Price (payable as herein provided, upon Redemption, Purchase at Holder's Option or Repurchase Upon Fundamental Change),
(B) a Default or Event of Default arising from a failure by the Company to convert any Securities in accordance with this Indenture or (C) any Default or Event of Default in respect of
any provision of this Indenture or the Securities which, under Section 9.02, cannot be modified or amended without the consent of the Holder of each outstanding Security affected. When a
Default or an Event of Default is waived, it is cured and ceases to exist for all purposes under this Indenture. This Section 6.04 shall be in lieu of TIA § 316(a)(1)(B), and, as
permitted by the TIA, TIA § 316(a)(1)(B) is hereby expressly excluded from this Indenture. 

        Section 6.05
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, is unduly prejudicial to the rights of
other Holders or would involve the Trustee in personal liability unless the Trustee is offered indemnity reasonably satisfactory to it; provided, that
the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction. This Section 6.05 shall be in lieu of TIA § 316(a)(1)(A), and, as
permitted by the TIA, TIA § 316(a)(1)(A) is hereby expressly excluded from this Indenture. 

28

 

        Section 6.06  Limitation on Suits. 

        Except
as provided in Section 6.07, a Securityholder may not institute any proceeding under this Indenture, or for the appointment of a receiver or a trustee, or for any other
remedy under this Indenture unless: 

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

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

        (iii)  such
Holder or Holders offer and, if requested, provide to the Trustee indemnity reasonably satisfactory to the Trustee against any loss, liability or expense to or of
the Trustee in connection with pursuing such remedy; 

        (iv)  the
Trustee does not comply with the request within sixty (60) days after receipt of such notice, request and offer of indemnity; and 

         (v)  during
such sixty (60) day period, the Holders of a majority in aggregate principal amount of the Securities then outstanding do not give the Trustee a direction
inconsistent with the request. 

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

        Section 6.07
Rights of Holders to Receive Payment. 

        Notwithstanding
any other provision of this Indenture, the right of any Holder to receive payment of all amounts due with respect to the Securities, on or after the respective due dates
as provided herein, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of the Holder. 

        Notwithstanding
any other provision of this Indenture, the right of any Holder to convert the Security in accordance with this Indenture, or to bring suit for the enforcement of such
right, shall not be impaired or affected without the consent of the Holder. 

        Section 6.08
Collection Suit by Trustee. 

        If
an Event of Default specified in Section 6.01(i) or (ii) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express
trust against the Company for the whole amount due with respect to the Securities, including any unpaid and accrued interest and interest on overdue principal and, to the extent lawful, interest and
such further amount as shall be sufficient to
cover the costs and expenses of collection, including the reasonable compensate expenses, disbursements and advances of the Trustee; its agents and counsel. 

        Section 6.09
Trustee May File Proofs of Claim. 

        The
Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee, any predecessor Trustee and the
Securityholders allowed in any judicial proceedings relative to the Company or its creditors or properties. 

        The
Trustee may collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same, and any custodian, receiver, assignee, trustee,
liquidator, sequestrator or similar official in any 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 the Trustee any amount due 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 7.07. 

29

 

        Nothing
herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement,
adjustment or composition affecting the Securities or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 

        Section 6.10  Priorities. 

        If
the Trustee collects any money pursuant to this Article VI, it shall pay out the money in the following order: 

	First:	 	to the Trustee for amounts due under Section 7.07;
	

Second:	
 	

to Securityholders for all amounts due and unpaid on the Securities, without preference or priority of any kind, according to the amounts due and payable on the Securities; and
	

Third:	
 	

the balance, if any, to the Company.

        The
Trustee, upon prior written notice to the Company, may fix a record date and payment date for any payment by it to Securityholders pursuant to this Section 6.10. At least
fifteen (15) days before each such record date, the Trustee shall mail to each Holder and the Company a written notice that states such record date and payment date and the amount of such
payment. 

        Section 6.11
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 other than the Trustee of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including
reasonable attorneys' fees, 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 6.11 does
not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07 or a suit by Holders of more than ten percent (10%) in aggregate principal amount of the outstanding Securities. 

ARTICLE VII.

        (a)   If
an Event of Default 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

expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but in the case of any such certificates or opinions which by any
provision hereof are specifically required to be furnished to the Trustee, the Trustee shall examine the certificates and opinions 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). 

30

 

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

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

         (ii)  the
Trustee shall be not liable 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 6.05. 

        (d)   Every
provision of this Indenture that in any way relates to the Trustee is subject to the provisions of this Section 7.01.

        (a)   Subject
to Section 7.01, the Trustee may conclusively rely on any document believed by it to be genuine and to have been signed or presented by the proper person.

Fundamental Change except any Default, Event of Default, Fundamental Change, Make-Whole Fundamental Change or Public Acquirer Fundamental Change of which a Responsible Officer of the
Trustee shall have received written notification or obtained actual knowledge. Except as otherwise provided herein, the Trustee may, in the absence of such actual knowledge or receipt of such written
notification, conclusively assume that there is no Default, Event of Default, Fundamental Change, Make-Whole Fundamental Change or Public Acquirer Fundamental Change. Delivery of reports,
information and documents to the Trustee under Article IV (other than Sections 4.04 and 4.07) is for informational purposes only and the receipt by the Trustee of the foregoing shall not

which each of the Trustee is entitled to rely on Officer's Certificates). 

        (h)   The

might be incurred by it in compliance with such request or direction. 

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

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

        (k)   The
Trustee shall not be required to expend or risk its own funds or otherwise incur financial liability for the performance of any of its duties hereunder or the
exercise of any of its rights or powers if there is reasonable ground for believing that the repayment of such funds or reasonably adequate indemnity against such risk or liability is not assured to
it. 

        (l)    The
Trustee shall not have any duty (i) to see to any recording, filing or depositing of this Indenture or any Indenture referred to herein or any financing
statement or continuation statement evidencing a security interest, or to see to the maintenance of any such recording or filing or depositing or to any rerecording, refiling or redepositing of any
thereof or (ii) to see to any insurance. 

        (m)  The
rights 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 other
than for its negligence or willful misconduct in the performance of such act. 

        (n)   The
Trustee shall not be required to give any bond or surety in respect of the execution of the powers granted hereunder. 

        Section 7.03
Individual Rights of Trustee. 

        The
Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the Company or any of its Affiliates with the same rights
the Trustee would have if it were not Trustee. The Trustee, however, must comply with Sections 7.10 and 7.11. 

32

 

        Section 7.04
Disclaimer of the Trustee. 

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

        Section 7.05
Notice of Defaults. 

        If
a Default or Event of Default occurs and is continuing as to which the Trustee has received notice pursuant to the provisions of this Indenture, or as to which a Responsible Officer
of the Trustee shall have actual knowledge, then the Trustee shall mail to each Holder a notice of the Default or Event of Default within thirty (30) days after receipt of such notice or after
acquiring such knowledge, as applicable, unless such Default or Event of Default has been cured or waived; provided, however, that,
except in the case of a Default or Event of Default in payment of any amounts due with respect to any Security or an Event of Default arising from a failure by the Company to convert any Securities in
accordance with this Indenture, the Trustee may withhold such notice if, and so long as it in good faith determines that, withholding such notice is in the best interests of Holders. 

        Section 7.06
Reports by Trustee to Holders. 

        Within
sixty (60) days after each May 15, beginning with May 15, 2007, the Trustee shall mail to each Securityholder if required by TIA § 313(a) a
brief report dated as of such May 15 that complies with TIA § 313(c). In such event, the Trustee also shall comply with TIA § 313(b) and TIA
§ 313(d). 

        A
copy of each report at the time of its mailing to Securityholders shall be mailed by first class mail to the Company and filed by the Trustee with the SEC and each stock exchange, if
any, on which the Securities are listed. The Company shall promptly notify the Trustee of the listing or delisting of the Securities on or from any stock exchange. 

        Section 7.07
Compensation and Indemnity. 

        The
Company shall pay to the Trustee from time to time such compensation for its services as shall be agreed upon in writing. The Trustee's compensation shall not be limited by any law
on compensation of a trustee of an express trust. The Company shall reimburse the Trustee upon request for all reasonable out-of-pocket expenses incurred by them pursuant to,
and in accordance with, any provision hereof. Such expenses shall include the reasonable compensation and out-of-pocket expenses of the agents and counsel of the Trustee. 

        The
Company shall indemnify the Trustee and any of its officers, directors, employees, representatives and agents against any and all loss, liability, damage, claim or expense (including
the reasonable fees and expenses of counsel and taxes other than those based upon the income of the Trustee) incurred by it in connection with the acceptance or administration of this trust and the
performance of its duties hereunder, including the reasonable costs and expenses of defending itself against any claim (whether asserted by the Company, any Holder or any other Person) or liability in
connection with the exercise or performance of any of its powers and duties hereunder. The Company need not pay any settlement made without its consent, which consent shall not be unreasonably
withheld or delayed. The Trustee shall notify the Company promptly of any claim for which it may seek indemnification. The Company need not reimburse any expense or indemnify against any loss or
liability incurred by the Trustee through the negligence, bad faith or willful misconduct of the Trustee. 

        Notwithstanding
anything herein to the contrary, to the extent permitted by the TIA, in no event shall the Trustee be liable for special, indirect or consequential losses or damages of
any kind whatsoever (including, without limitation, lost profits), even if the Trustee has been advised of the likelihood of such losses or damages and regardless of the form of action. 

33

 

        To
secure the Company's payment obligations in this Section 7.07, the Trustee shall have a lien prior to the Securities on all money or property held or collected by the Trustee
pursuant to this Indenture, except that held in trust to pay amounts due on particular Securities. 

        The
indemnity obligations of the Company with respect to the Trustee provided for in this Section 7.07 shall survive any resignation or removal of the Trustee. 

        When
the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(ix) or (x) occurs, the expenses and the compensation for the
services are intended to constitute expenses of administration under any Bankruptcy Law. 

        Section 7.08  Replacement of Trustee. 

        A
resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon such successor's acceptance of appointment as provided in this
Section 7.08. 

        The
Trustee may resign by so notifying the Company in writing thirty (30) Business Days prior to such resignation. 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 in writing and may appoint a successor Trustee with the Company's consent. The Company may remove the
Trustee if: 

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

         (ii)  the
Trustee is adjudged a bankrupt or an insolvent; 

        (iii)  a
receiver or other public officer takes charge of the Trustee or its property; or 

        (iv)  the
Trustee becomes incapable of acting. 

        If
the Trustee resigns or is removed or if a vacancy exists in the office of Trustee, for any reason, the Company shall promptly appoint a successor Trustee. 

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

        If
the Trustee fails to comply with Section 7.10, the Company or any Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of
a successor Trustee. 

        Each
successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon, 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. The successor Trustee shall mail a notice of its succession to
Securityholders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee subject to the lien provided for in Section 7.07. 

        Section 7.09  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 to, another corporation, the successor corporation
without any further act shall be the successor Trustee if such successor corporation is otherwise eligible hereunder. 

        Section 7.10
Eligibility; Disqualification. 

        There
shall at all times be a Trustee hereunder, which (A) is an entity organized and doing business under the laws of the United States of America or of any state thereof,

34

 

federal
or state authorities and (D) has a combined capital and surplus of at least $100 million as set forth in its most recent published annual report of condition. The Trustee shall
comply with TIA § 310(b). Nothing in this Indenture shall prevent the Trustee from filing with the SEC the application referred to in the penultimate paragraph of TIA § 310(b). 

        Section 7.11  Preferential Collection of Claims Against Company. 

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

ARTICLE VIII.
  

 DISCHARGE OF INDENTURE  

        Section 8.01 Termination of the Obligations of the Company. 

        This
Indenture shall cease to be of further effect if (a) either (i) all outstanding Securities (other than Securities replaced pursuant to Section 2.07 hereof) have
been delivered to the Trustee for cancellation or (ii) all outstanding Securities have become due and payable on the Maturity Date or upon Purchase at Holder's Option, Redemption or Repurchase
Upon Fundamental Change, and in any case the Company irrevocably deposits, after to the applicable due date, with the Paying Agent (if the Paying Agent is not the Company or any of its Affiliates)
cash in money of the United States that at the time of payment is legal tender for payment of public and private debts, sufficient to pay all amounts due and owing on all outstanding Securities (other
than Securities replaced pursuant to Section 2.07 hereof) on the Maturity Date or an Option Purchase Date, Redemption Date or Fundamental Change Repurchase Date, as the case may be;
(b) the Company pays to the Trustee all other sums payable hereunder by the Company; (c) no Default or Event of Default with respect to the Securities shall exist on the date of such
deposit; (d) such deposit will not result in a breach or violation of, or constitute a Default or Event of Default under, this Indenture; and (e) the Company has delivered to the Trustee
an Officer's Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for herein relating to the satisfaction and discharge of this Indenture have been complied with;  provided, however,
 that Sections 2.02, 2.03, 2.04, 2.05, 2.06, 2.07, 2.08, 2.09, 2.10, 2.11, 2.12, 2.15, 2.16, 2.17, 3.05, 3.08, 3.09, 4.01,
4.02, 4.05, 4.06, 7.07 and 7.08 and Articles VIII and X shall survive any discharge of this
Indenture until such time as the Securities have been paid in full and there are no Securities outstanding. 

        Section 8.02
Application of Trust Money. 

        The
Trustee or Paying Agent, as applicable, shall hold in trust all money deposited with it pursuant to Section 8.01 and shall apply such deposited money through the Paying Agent
and in accordance with this Indenture to the payment of amounts due on the Securities. 

        Section 8.03
Repayment to Company. 

        The
Trustee and the Paying Agent shall promptly notify the Company of, and pay to the Company upon the request of the Company, any excess money held by them at any time. The Trustee or
the Paying Agent, as the case may be, shall provide written notice to the Company of any money that has been held by it and has, for a period of two (2) years, remained unclaimed for the
payment of the principal of, or any accrued and unpaid interest on, the Securities. The Trustee and the Paying Agent shall pay to the Company upon the written request of the Company any money held by
them for the payment of the principal of, premium, if any, or any accrued and unpaid interest on, the notes that remains unclaimed for two (2) years; provided,
however, that the Trustee or such Paying Agent, before being required to make any such repayment, may (in no event later than five (5) days after the Company requests
repayment pursuant to this Section 8.03), at the expense of the Company, cause to be published once in a newspaper of general circulation in the City of New York or cause to be mailed 

35

 

to
each Holder, notice stating that such money remains unclaimed and that, after a date specified therein, which shall not be less than thirty (30) days from the date of such publication or
mailing, any unclaimed balance of such money then remaining will be repaid to the Company. After payment to the Company, Securityholders entitled to the money must look to the Company for payment as
general creditors, subject to applicable law, and all liability of the Trustee and the Paying Agent with respect to such money and payment shall, subject to applicable law, cease. 

        Section 8.04
Reinstatement. 

        If
the Trustee or Paying Agent is unable to apply any money in accordance with Sections 8.01 and 8.02 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, the obligations of the Company under this Indenture and the Securities shall be revived and reinstated as
though no deposit had occurred pursuant to Sections 8.01 and 8.02 until such time as the Trustee or Paying Agent is
permitted to apply all such money in accordance with Sections 8.01 and 8.02; provided, however, that if the Company has made any payment of amounts due
with respect to any Securities because of the reinstatement of its obligations, then the Company shall be subrogated to the rights of the Holders of such Securities to receive such payment from the
money held by the Trustee or Paying Agent. 

ARTICLE IX.
  

 AMENDMENTS  

        Section 9.01 Without Consent of Holders. 

        The
Company, with the consent of the Trustee may amend or supplement this Indenture or the Securities without notice to or the consent of any Securityholder: 

          (i)  to

36

 

        In
addition, the Company and the Trustee may enter into a supplemental indenture without the consent of Holders of the Securities to cure any ambiguity, defect, omission or inconsistency
in this Indenture in a manner that does not, individually or in the aggregate with all other modifications made or to be made to the Indenture, adversely affect the rights of any Holder in any
material respect. The Company and the Trustee may also enter into a supplemental indenture without the consent of Holders of the Securities in order to conform this Indenture to the "Description of
the notes" contained in this Prospectus Supplement. 

        Section 9.02
With Consent of Holders. 

        The
Company, with the consent of the Trustee may amend or supplement this Indenture or the Securities without notice to any Securityholder but with the written consent of the Holders of
at least a majority in aggregate principal amount of the outstanding Securities. Subject to Sections 6.04 and 6.07, the Holders of a majority in aggregate principal amount of the outstanding
Securities may, by notice to the Trustee, waive compliance by the Company with any provision of this Indenture or the Securities without notice to any other Securityholder. Notwithstanding anything
herein to the contrary, without the consent of each Holder of each outstanding Security affected, an amendment, supplement or waiver, including a waiver pursuant to Section 6.04, may not: 

          (i)  change
the stated maturity of the principal of, or the payment date of any installment of interest on, any Security; 

         (ii)  reduce
the principal amount of, or any premium or interest on, any Security; 

        (iii)  change
the place, manner or currency of payment of principal of, or any premium or interest on, any Security; 

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

         (v)  modify,
in a manner adverse to Holders, the provisions with respect to the right of Holders pursuant to Article III to require the Company to purchase Securities
on an Option Purchase Date or to repurchase Securities upon the occurrence of a Fundamental Change; 

        (vi)  adversely
affect the right of Holders to convert Securities in accordance with Article X; 

       (vii)  to
modify the ranking of the Securities in a manner adverse to Holders; 

      (viii)  reduce
the percentage of the aggregate principal amount of the outstanding Securities whose Holders must consent to a modification to or amendment of any provision of
this Indenture or the Securities; 

        (ix)  reduce
the percentage of the aggregate principal amount of the outstanding Securities whose Holders must consent to a waiver of compliance with any provision of this
Indenture or the Securities or a waiver of any Default or Event of Default; or 

         (x)  modify
the provisions of this Indenture with respect to modification and waiver (including waiver of a Default or an Event of Default), except to increase the percentage
required for modification or waiver or to provide for consent of each affected Holder. 

        Promptly
after an amendment, supplement or waiver under Section 9.01 or this Section 9.02 becomes effective, the Company shall mail, or cause to be mailed, to
Securityholders a notice briefly describing such amendment, supplement or waiver. Any failure of the Company to mail such notice shall not in any way impair or affect the validity of such amendment,
supplement or waiver. 

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

37

   
        Section 9.03 Compliance with Trust Indenture Act. 

        Every
amendment, waiver or supplement to this Indenture or the Securities shall comply with the TIA as then in effect. 

        Section 9.04
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. An amendment, supplement or
waiver becomes effective in accordance with its terms and thereafter binds every Holder. 

        After
an amendment, supplement or waiver becomes effective with respect to the Securities, it shall bind every Holder unless such amendment, supplement or waiver makes a change that
requires, pursuant to Section 9.02, the consent of each Holder affected. In that case, the amendment, supplement or waiver shall bind each Holder of a Security who has consented to it and,
provided that notice of such amendment, supplement or waiver is reflected on a Security that evidences the same debt as the consenting Holder's Security, every subsequent Holder of a Security or
portion of a Security that evidences the same debt as the consenting Holder's Security. 

        Nothing
in this Section 9.04 shall impair the Company's rights pursuant Section 9.01 to amend this Indenture or the Securities without the consent of any Securityholder in
the manner set forth in, and permitted by, such Section 9.01. 

        Section 9.05  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 as directed and prepared by the Company about the changed terms and return it to the
Holder. Alternatively, if the Company 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 9.06  Trustee Protected. 

        The
Trustee shall sign any amendment, supplemental indenture or waiver authorized pursuant to this Article IX; provided, however,
that the Trustee need not sign any amendment, supplement or waiver authorized pursuant to this Article IX that adversely affects the rights, duties, liabilities or immunities of the Trustee.
The Trustee shall be entitled to receive and conclusively rely upon an Opinion of Counsel as to legal matters and an Officer's Certificate as to factual matters that any supplemental indenture,
amendment or waiver is permitted or authorized pursuant to this Indenture. 

        Section 9.07  Effect of Supplemental Indentures. 

        Upon
the due execution and delivery of any supplemental indenture in accordance with this Article IX, this Indenture shall be modified in accordance therewith, and such
supplemental indenture shall form a part of this Indenture for all purposes, and, except as set forth in Sections 9.02 and 9.04, every Holder of Securities shall be bound thereby. 

38

 

ARTICLE X.
  

 CONVERSION  

        Section 10.01 Conversion Privilege; Restrictive Legends. 

        (a)   Subject
to the provisions of Article III, the Securities shall be convertible into cash or, at the Company's option, cash and shares of Common Stock (if
applicable) in accordance with this Article X and as set forth below if any of the following conditions are satisfied: 

          (i)  Conversion Based on Closing Sale Price of Common Stock. The Securities may be surrendered for conversion into cash or,
at the Company's option, cash and shares of Common Stock (if applicable) on any Business Day of a calendar quarter after the calendar quarter ending December 31, 2006 (and only
during such calendar quarter), if the Closing Sale Price for each of twenty (20) or more Trading Days in a period of thirty (30) consecutive Trading Days ending on the last Trading Day
of the immediately preceding calendar quarter exceeds one hundred and thirty percent (130%) of the Conversion Price in effect on the last Trading Day of the immediately preceding calendar quarter.
Solely for purposes of determining whether the Securities shall have become convertible pursuant to this Section 10.01(a)(i), the Board of Directors shall, in its good faith determination,
which shall be described in a Board Resolution, make appropriate adjustments to the Closing Sale Prices and/or such Conversion Price used to determine whether the Securities shall have become
convertible pursuant to this Section 10.01(a)(i) to account for any adjustments to the Conversion Rate which shall have become effective, or any event requiring an adjustment to the
Conversion Rate where the Ex-Date of such event occurs, during the period of thirty (30) consecutive Trading Days ending on the last Trading Day of the immediately preceding
calendar quarter. 

         (ii)  Conversion Upon Satisfaction of Trading Price Condition. The Securities may be surrendered for conversion into cash or,
at the Company's option, cash and shares of Common Stock (if applicable) during the five (5) consecutive Business Days immediately after any five (5) consecutive Trading Day period (such
five (5) consecutive Trading Day period, the "Note Measurement Period") in which the average Trading Price per $1,000 principal amount of the
Securities was equal to or less than ninety eight percent (98%) of the average Conversion Value (as defined below) during the Note Measurement Period (such condition, the
"Trading Price Condition"). The Bid Solicitation Agent shall not have any obligation to determine the Trading Price unless the Company has requested
such determination in writing, and the Company shall have no obligation to make such request unless a Holder provides the Company with reasonable written evidence that the Trading Price per $1,000
principal amount of the Securities would be equal to or less than ninety eight percent (98%) of the Conversion Value. Upon receipt of such evidence, the Company shall instruct the Bid Solicitation
Agent in writing to determine the Trading Price per $1,000 principal amount of the Securities for each of the five (5) successive Trading Days immediately after the Company receives such
written evidence and on each Trading Day thereafter until the first Trading Day on which the Trading Price Condition is no longer satisfied. If the Company does not so instruct the Bid Solicitation
Agent after a Holder provides the Company with reasonable written evidence that the Trading Price per $1,000 principal amount of Securities would be less than 98% of the product of the Closing Sale
Price per share of Common Stock and the Conversion Rate, the Trading Price per $1,000 principal amount of Securities shall be deemed to be less than 98% of the product of the Closing Sale Price per
share of Common Stock and Conversion Rate on each Trading Day that the Company fails to do so. For purposes of this paragraph, the "Conversion Value"
per $1,000 principal amount of Securities on a given Trading Day means the product of the Closing Sale Price of the Common Stock on such Trading Day and the Conversion Rate in effect on such Trading
Day. 

39

 

        (iii)  Conversion Based on Redemption. If the Securities are called for Redemption pursuant to Section 3.01, Holders
may surrender Securities for conversion into cash or, at the Company's option, cash and shares of Common Stock (if applicable); provided, however, that
Securities may be surrendered for conversion pursuant to this paragraph only until the close of business on the Business Day immediately preceding the Redemption Date. 

        (iv)  Conversion Upon Certain Distributions. If the Company takes any action, or becomes aware of any event, that would
require an adjustment to the Conversion Rate pursuant to Sections 10.05(b), 10.05(c), 10.05(d) or 10.05(e), the Securities may be surrendered for conversion into cash or, at the Company's option, cash
and shares of Common Stock (if applicable) beginning on the date the Company mails the notice to the Holders as provided in Section 10.10 (or, if earlier, the date the Company is required under
this Indenture to mail such notice) and at any time thereafter until the close of business on the Business Day immediately preceding the Ex-Date (as defined in Section 10.05(g)) of
the applicable transaction or until the Company announces that such transaction will not take place. 

         (v)  Conversion Upon Occurrence of Certain Corporate Transactions. If either: 

        (A)  a
Fundamental Change or a Make-Whole Fundamental Change occurs; or 

        (B)  the
Company is a party to a consolidation, merger or binding share exchange, sale of all or substantially all of the Company's properties and assets or other similar
transaction, in each case, pursuant to which the Common Stock would be converted into or exchanged for, or would constitute solely the right to receive, cash, securities or other property, 

then,
in each case, the Securities may be surrendered for conversion into cash or, at the Company's option, cash and shares of Common Stock, if applicable, at any time during the period that begins
on, and includes, the date that is thirty (30) Business Days prior to the date originally announced by the Company as the anticipated effective date of such transaction and ends on, and
includes, the date that is thirty (30) Business Days after the actual effective date of such transaction; provided, however, that if such
transaction is a Make-Whole Fundamental Change, then the Securities may also be surrendered for conversion into cash or, at the Company's option, cash and shares of Common Stock, if
applicable, at any time during the Make-Whole Conversion Period applicable to such Make-Whole Fundamental Change; and provided,  further, that if such
transaction is a Fundamental Change, then the Securities may also be surrendered for conversion into cash and, if applicable,
shares of Common Stock, if applicable, at any time until, and including, the Fundamental Change Repurchase Date applicable to such Fundamental Change. The Company shall mail to Holders, at their
addresses appearing in the Security register, notice of the anticipated effective date of any transaction described clause (A) or clause (B) above. The Company shall make this mailing at
least 30 Business Days before the first anticipated effective date of such transaction. 

        (vi)  Conversion During Specified Periods. The Securities may be surrendered for conversion into cash or, at the Company's
option, cash and shares of Common Stock (if applicable) at any time from, and including, October 15, 2011 to, and including, November 15, 2011 and at any time on or after
November 15, 2024 and before the close of business on the Business Day immediately preceding the Maturity Date, subject to earlier Redemption, Purchase at Holder's Option of Repurchase Upon
Fundamental Change. 

        (b)   The
initial Conversion Rate shall be [    ] shares of Common Stock per $1,000 principal amount of Securities. The Conversion Rate shall
be subject to adjustment in accordance with Sections 10.05 through 10.14. 

        (c)   Subject
to the last sentence of Section 10.01(a)(v) and Section 10.10, whenever any event described in Section 10.01 shall occur which shall
cause the Securities to become convertible as 

40

 

provided
in this Article X, the Company shall promptly deliver, in accordance with Section 14.02, written notice of the convertibility of the Securities to the Trustee, the Conversion
Agent and each Holder and shall, as soon practicable, but in no event later than the open of business on the second Business Day following the date the Securities shall become convertible as provided
in this Article X as a result of such event, publicly announce, through a reputable national newswire service, and publish on the Company's website, that the Securities have become convertible.
Such written notice, public announcement and publication shall include: 

          (i)  a
description of such event; 

         (ii)  a
description of the periods during which the Securities shall be convertible as provided in this Article X as a result of such event; 

        (iii)  the
anticipated effective date of such event, if applicable; and 

        (iv)  the
procedures Holders must follow to convert their notes in accordance with this Article X, including the name and address of the Conversion Agent. 

        A
Holder may convert a portion of the principal amount of a Security if such portion is $1,000 principal amount or an integral multiple of $1,000 principal amount. Provisions of this
Indenture that apply to conversion of all of a Security also apply to conversion of a portion of such Security. 

        Section 10.02
Conversion Procedure And Payment Upon Conversion. 

        (a)   To
convert a Security, a Holder must (1) complete and sign the Conversion Notice, with appropriate signature guarantee, on the back of the Security,
(2) surrender the Security to a Conversion Agent, (3) furnish appropriate endorsements and transfer documents if required by the Registrar or Conversion Agent, (4) pay the amount
of interest, if any, the Holder must pay in accordance with Section 10.02(d) and (5) pay any tax or duty if required pursuant to Section 10.03. In addition, in the case of a
Global Security, a converting Holder must comply with the applicable procedures of the Depository. A Holder may convert a portion of a Security if the portion is $1,000 principal amount or an integral
multiple of $1,000 principal amount. Upon conversion of a Holder's Security, the Company shall deliver, through the Conversion Agent, to such converting Holder a settlement amount, per $1,000
principal amount of Securities being converted, equal to the sum of the Daily Settlement Amounts for each of the 20 Trading Days during the Cash Settlement Averaging Period (the
"Settlement Amount"). 

        The
"Daily Settlement Amount" for each of the 20 Trading Days during the Cash Settlement Averaging Period shall consist of (i) the
Daily Principal Return and (ii) the Daily Share Amount; provided, however, that the Company shall not issue fractional shares of Common Stock and
shall instead deliver cash (in addition to any other consideration payable upon such conversion) in an amount equal to the value of such fraction computed on the basis of the Closing Sale Price of the
Common Stock on the last Trading Day of the Cash Settlement Averaging Period. 

        The
Company shall deliver such Settlement Amount as soon as practicable following the date (the "Conversion Date") on which such Holder
satisfies all the requirements for such conversion specified above, but in no event more than three (3) Business Days after the last Trading Day in the Cash Settlement Averaging Period
applicable to such conversion; provided, however, that any Make-Whole Consideration payable pursuant to Section 10.14 shall be
delivered by the Company within the time period specified in Section 10.14. 

        (b)   "Cash Settlement Averaging Period" shall mean, with respect to a Security that is surrendered for conversion in
accordance with this Article X, the twenty (20) consecutive Trading-Day period that begins on, and includes, the second (2nd) Trading Day after the day such Security is
surrendered for such conversion. 

41

 

        "Daily Principal Return" shall mean, with respect to each Trading Day in the Cash Settlement Averaging Period, the lesser of fifty dollars
($50) and the Daily Conversion Value for such Trading Day. 

        "Daily Conversion Value" shall mean, with respect to each Trading Day in the Cash Settlement Averaging Period, one-twentieth
(1/20th) of the product of (i) the Conversion Rate in effect on such Trading Day and (ii) the VWAP Price of Common Stock on such Trading Day. 

        "Daily Share Amount" shall mean, with respect to a Trading Day, an amount equal to the following: (i) if the Daily Conversion Value
for such Trading Day is equal to or lesser than fifty dollars ($50), then the Daily Share Amount with respect to such Trading Day shall mean an amount equal to zero (0); and (ii) if the Daily
Conversion Value for such Trading Day exceeds fifty dollars ($50), then the Daily Share Amount with respect to such Trading Day shall mean a fraction (a) whose numerator is the excess of such
Daily Conversion Value over fifty dollars ($50) and (b) whose denominator is the VWAP Price of Common Stock on such Trading Day. 

        (c)   On
and after the last Trading Day of the relevant Cash Settlement Averaging Period, the person in whose name any certificate representing Net Shares (other than Net
Shares comprised of Make-Whole Consideration), if any, shall be registered shall be treated as a stockholder of record of the Company, and on and after the relevant Conversion Date, all
rights of the Holder of such Security shall terminate, other than the right to receive the consideration deliverable upon conversion of such Security as provided herein. In the case of Net Shares
comprised of Make-Whole Consideration, on and after the later of (x) the last Trading Day of the relevant Cash Settlement Averaging Period and (y) the Effective Date of the
relevant Make-Whole Fundamental Change, the person in whose name any certificate representing such Net Shares, if any, shall be registered shall be treated as a stockholder of record of
the Company. A Holder of Securities is not entitled, as such, to any rights of a holder of Common Stock until such Holder has converted its Securities into shares of Common Stock (to the extent such
Securities are convertible into Shares of Common Stock) or is deemed to be a stockholder of record of the Company, as provided in this Section 10.02(c). 

        (d)   Except
as provided in the Securities or in this Article X, no payment or adjustment will be made for accrued interest on a converted Security or for dividends on
any Common Stock issued on or prior to conversion. Upon the conversion of any Security, the accrued but unpaid interest attributable to the period from the Issue Date to the Conversion Date with
respect to the converted Securities, shall not be cancelled, extinguished or forfeited, but rather shall be deemed to be paid in full to the Holder thereof through delivery of cash and shares of
Common Stock, if any, in exchange for the Securities being converted pursuant to the provisions hereof. If any Holder surrenders a Security for conversion after the close of business on the record
date for the payment of an installment of interest and on or before the related interest payment date, then, notwithstanding such conversion, the accrued and unpaid interest payable with respect to
such Security on such interest payment date shall be paid, on such interest payment date, to the Holder of record of such Security at the close of business on such record date;  provided, that such
Security, when surrendered for conversion to the Conversion Agent on behalf of the Company, must be accompanied by payment in cash
of an amount equal to the interest payable on such interest payment date on the portion of the Security so converted; provided further, however, that
such payment to the Conversion Agent described in the immediately preceding proviso in respect of a Security surrendered for conversion shall not be required if such Security is called for Redemption
pursuant to Sections 3.01 through 3.04, or if the Holder converts Securities pursuant to a Fundamental Change and the Company has specified a Redemption Date or a Fundamental Change Repurchase Date,
as applicable, in either case that is after a record date for the payment of an installment of interest and on or before the related interest payment date; provided
further, that, if the Company shall have, prior to the Conversion Date with respect to a Security, defaulted in a payment of interest on such Security, then in no event shall
the Holder of such Security who surrenders such Security for conversion be required to pay such defaulted interest or the interest that shall have accrued on such defaulted interest pursuant to
Section 2.12 or otherwise (it being 

42

 

understood
that nothing in this Section 10.02(d) shall affect the Company's obligations under Section 2.12). 

        (e)   If
a Holder converts more than one Security at the same time, the number of full shares of Common Stock issuable upon such conversion, if any, shall be based on the
total principal amount of all Securities converted. 

        (f)    Upon
surrender of a Security that is converted in part, the Trustee shall authenticate for the Holder a new Security equal in principal amount to the unconverted portion
of the Security surrendered and the aggregate sum of all Daily Settlement Amounts for each of the twenty Trading Days during the applicable Cash Settlement Averaging Period (and not in respect of each
Daily Settlement Amount nor some portion of the Daily Settlement Amounts for one or some portion of the twenty Trading Days during the applicable Cash Settlement Averaging Period). 

        (g)   If
the last day on which a Security may be converted is a Legal Holiday in a place where a Conversion Agent is located, the Security may be surrendered to that
Conversion Agent on the next succeeding day that is not a Legal Holiday. 

        (h)   The
Company may elect to pay cash to the Holders surrendered for conversion in lieu of all or a portion of the Common Stock otherwise issuable pursuant to this
Article X. In such event, the close of business on the Business Day prior to the first scheduled Trading Day of the applicable Cash Settlement Averaging Period, the Company shall specify a
percentage of the Daily Share Amount that shall be settled in cash (the "Cash Percentage") and the amount of cash that the Company shall pay in respect
of each Trading Day in the applicable Cash Settlement Averaging Period will equal the product of: (1) the Cash Percentage, (2) the Daily Share Amount for such Trading Day and
(3) the VWAP Price of the Common Stock for such Trading Day. The number of shares of Common Stock that the Company shall deliver in respect of each Trading Day in the applicable Cash Settlement
Averaging 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 notify Holders of such Cash Percentage by notifying the Trustee (the "Cash Percentage Notice"). If the Company does not
specify a Cash Percentage by the close of business on the Trading Day prior to the scheduled first Trading Day of the applicable Cash Settlement Averaging Period, the Company shall settle 100% of the
Daily Share Amount for each Trading Day in the applicable Cash Settlement Averaging 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. The Company at its option, may revoke any Cash Percentage Notice by notifying the Trustee;
provided, that the Company shall revoke such notice by the close of business on the Business Day prior to the first scheduled Trading Day of the applicable Cash Settlement Averaging Period. 

        Section 10.03
Taxes on Conversion. 

        If
a Holder converts its Security, the Company shall pay any documentary, stamp or similar issue or transfer tax or duty due on the issue, if any, of shares of Common Stock upon the
conversion. However, such Holder shall pay any such tax or duty which is due because such shares are issued in a name other than such Holder's name. The Conversion Agent may refuse to deliver a
certificate representing the shares of Common Stock to be issued in a name other than such Holder's name until the Conversion Agent receives a sum sufficient to pay any tax or duty which will be due
because such shares are to be issued in a name other than such Holder's name. 

        Section 10.04  Company to Provide Stock. 

        The
Company shall at all times reserve out of its authorized but unissued Common Stock or Common Stock held in its treasury enough shares of Common Stock to permit the conversion, in
accordance herewith, of all of the Securities (assuming a Cash Percentage of 0% for all such 

43

 

conversions).
The shares of Common Stock, if any, due upon conversion of a Global Security shall be delivered by the Company in accordance with the Depositary's customary practices. 

        All
shares of Common Stock which may be issued upon conversion of the Securities shall be validly issued, fully paid and non-assessable and shall be free of preemptive or
similar rights and free of any lien or adverse claim. 

        The
Company shall comply with all securities laws regulating the offer and delivery of shares of Common Stock upon conversion of Securities and shall list such shares on each national
securities exchange or automated quotation system on which the Common Stock is listed. 

        Section 10.05  Adjustment of Conversion Rate. 

        The
Conversion Rate shall be subject to adjustment from time to time as follows: 

        (a)   If
the Company shall (1) pay a dividend in shares of Common Stock to all holders of Common Stock, (2) make a distribution in shares of Common Stock to all
holders of Common Stock, (3) subdivide the outstanding shares of Common Stock into a greater number of shares of Common Stock or (4) combine the outstanding shares of Common Stock into a
smaller number of shares of Common Stock, the Conversion Rate shall be adjusted by multiplying the Conversion Rate in effect immediately prior to the open of business on the Ex-Date or
effective date, as applicable, of such dividend, distribution, subdivision or combination by the number of shares of Common Stock which a person who owns only one share of Common Stock immediately
before the Ex-Date or effective date, as applicable, of such dividend, distribution, subdivision or combination and who is entitled to participate in such dividend, distribution,
subdivision or combination would own immediately after giving effect to such dividend, distribution, subdivision or combination. Any adjustment made pursuant to this Section 10.05(a) shall
become effective at the opening of business on the Ex-Date or effective date, as the case may be, of such dividend, distribution, subdivision or combination. Other than in the event of a
combination, in no event shall the Conversion Rate be decreased pursuant to this Section 10.05(a). 

        (b)   If
the Company shall distribute rights or warrants to all or substantially all holders of Common Stock, entitling them, for a period expiring not more than sixty
(60) calendar days immediately following the record date for the determination of holders of Common Stock entitled to receive such rights or warrants, to subscribe for or purchase shares of
Common Stock at a price per share that is less than the Current Market Price (as determined pursuant to Section 10.05(g)) per share of Common Stock on the record date for the determination of
holders of Common Stock entitled to receive such rights or warrants, the Conversion Rate shall be increased by multiplying the Conversion Rate in effect immediately prior to the opening of business on
the Ex-Date for such distribution by a fraction of which (A) the numerator shall be the sum of (I) the number of shares of Common Stock outstanding at the opening of business
on the Ex-Date for such distribution and (II) the aggregate number of shares (the "Underlying Shares") of Common Stock underlying all
such issued rights or warrants (whether by exercise, conversion, exchange or otherwise), and (B) the denominator shall be the sum of (I) number of shares of Common Stock outstanding at
the opening of business on the Ex-Date for such distribution and (II) the number of shares of Common Stock that the aggregate exercise, conversion, exchange or other price at which
the Underlying Shares may be
subscribed for or purchased pursuant to such rights or warrants would purchase at such Current Market Price per share of Common Stock; provided,
however, no adjustment shall be made pursuant to this Section 10.05(b) solely by reason of a distribution of rights pursuant to a Rights Plan so long as the Company has
complied with the provisions of Section 10.13 with respect to such Rights Plan and such related distribution. Such increase shall become effective at the opening of business on the
Ex-Date for such distribution. In no event shall the Conversion Rate be decreased pursuant to this Section 10.05(b). 

44

  

        (c)   Except
as set forth in the immediately succeeding paragraph, if the Company shall dividend or distribute to all or substantially all holders of Common Stock shares of
Capital Stock of the Company or any existing or future Subsidiary (other than Common Stock), evidences of Indebtedness or other assets (other than dividends or distributions requiring an adjustment to
the Conversion Rate in accordance with Sections 10.05(d) or 10.05(e)), or shall dividend or distribute to all or substantially all holders of Common Stock rights or warrants to subscribe for or
purchase securities (other than dividends or distributions of rights or warrants requiring an adjustment to the Conversion Rate in accordance with Section 10.05(b)), then in each such case the
Conversion Rate shall be increased by multiplying the Conversion Rate in effect immediately prior to the opening of business on the Ex-Date for such dividend or distribution by a fraction
of which (A) the numerator shall be the Current Market Price per share of Common Stock (as determined pursuant to Section 10.05(g)) on such Ex-Date and (B) the
denominator shall be an amount equal to (I) such Current Market Price per share of Common Stock less (II) the fair market value (as determined in good faith by the Board of Directors,
whose determination shall be conclusive and described in a Board Resolution), on such Ex-Date, of the portion of the shares of Capital Stock, evidences of Indebtedness, assets, rights and
warrants to be dividended or distributed applicable to one share of Common Stock, such increase to become effective at the opening of business on the Ex-Date for such dividend or
distribution; provided, however, that if such denominator is equal to or less than zero, then, in lieu of the foregoing adjustment to the Conversion
Rate, adequate provision shall be made so that each Holder of Securities shall have the right to receive on the date on which the relevant dividend or distribution is paid to holders of Common Stock,
for each $1,000 aggregate principal amount of Securities, the number of shares of such Capital Stock, the amount of such Indebtedness or other assets, or the number of such rights or warrants, as the
case may be, that such Holder would have received in connection with such dividend or distribution had such Holder owned a number of shares of Common Stock equal to the Conversion Rate on the
Ex-Date for such dividend or distribution. 

        Notwithstanding
anything to the contrary in this Section 10.05(c), if, in a distribution requiring an adjustment to the Conversion Rate pursuant to the immediately preceding
paragraph, the property distributed by the Company to all Holders of Common Stock consists solely of Capital Stock, or similar equity interests in, a Subsidiary or other business unit of the Company,
which Capital Stock or interests are, or will be upon completion of such distribution, listed on a national securities exchange or quoted on an automated quotation system and closing sale prices for
such Capital Stock or interests are readily available (a "Spin-Off"), then in lieu of adjusting the Conversion Rate in accordance with the
immediately preceding paragraph, the Conversion Rate shall be increased by multiplying the Conversion Rate in effect immediately prior to the opening of business on the thirteenth (13th) Trading Day
immediately following the effective date of such Spin-Off by a fraction (I) whose numerator is the sum of (A) the average of the Closing Sale Prices per share of Common Stock
for the ten (10) consecutive Trading Days commencing on, and including, the third (3rd) Trading Day immediately following the effective date of such Spin-Off and (B) the
product of (i) the average of the Closing Sale Prices per share or unit, as applicable, of such Capital Stock or interests (determined as if such shares or units were shares of Common Stock for
purposes of the definition of "Closing Sale Price") for the for the ten (10) consecutive Trading Days commencing on, and including, the third (3rd) Trading Day immediately following the
effective date of such Spin-Off and (ii) number of shares or units, as applicable, of such Capital Stock or interests distributed per share of Common Stock; and (II) whose
denominator is the average of the Closing Sale Prices per share of Common Stock for the ten (10) consecutive Trading Days commencing on, and including, the third (3rd) Trading Day immediately
following the effective date of such Spin-Off. The average Closing Sale Prices referred to in the immediately preceding sentence shall be subject to appropriate adjustments, in the
Company's good faith determination, to account for other distributions, stock splits and combinations, stock dividends, 

45

 

reclassifications
and similar events occurring during the relevant period. Each adjustment to the Conversion Rate made pursuant to this paragraph shall become effective at the opening of business on
the thirteenth (13th) Trading Day immediately following the effective date of such Spin-Off. 

        In
no event shall the Conversion Rate be decreased pursuant to this Section 10.05(c). 

        (d)   If
the Company shall, by dividend or otherwise, at any time make a distribution of cash (excluding any cash that is distributed as part of a distribution requiring a
Conversion Rate adjustment pursuant to Section 10.05(e)) to all or substantially all holders of Common Stock, the Conversion Rate shall be increased by multiplying the Conversion Rate in effect
immediately prior to the opening of business on the Ex-Date for such dividend or distribution by a fraction (A) whose numerator shall be the Current Market Price per share of Common
Stock (as determined pursuant to Section 10.05(g)) on such Ex-Date and (B) whose denominator shall be an amount equal to (I) such Current Market Price per share of
Common Stock less (II) the amount of the distribution per share of Common Stock; provided however, that if the denominator of such fraction shall
be equal to or less than zero, in lieu of the foregoing adjustment, adequate provision shall be made so that each Holder of Securities shall have the right to receive on the date on which the relevant
dividend or distribution is paid to holders of Common Stock, for each $1,000 aggregate principal amount of Securities, the amount of cash that such Holder would have received in connection with such
dividend or distribution had such Holder owned a number of shares of Common Stock equal to the Conversion Rate on the
Ex-Date for such dividend or distribution. An adjustment to the Conversion Rate pursuant to this Section 10.05(d) shall become effective at the opening of business on the
Ex-Date for such dividend or distribution. In no event shall the Conversion Rate be decreased pursuant to this Section 10.05(d). 

        (e)   If
the Company or any Subsidiary shall distribute cash or other consideration in respect of a tender offer or exchange offer made by the Company or any Subsidiary for
all or any portion of the Common Stock where the sum of the aggregate amount of such cash distributed and the aggregate fair market value (as determined in good faith by the Board of Directors, whose
determination shall be conclusive and set forth in a Board Resolution), as of the Expiration Date (as defined below), of such other consideration distributed (such sum, the
"Aggregate Amount") expressed as an amount per share of Common Stock validly tendered or exchanged, and not withdrawn, pursuant to such tender offer or
exchange offer as of the Expiration Time (as defined below) (such tendered or exchanged shares of Common Stock, the "Purchased Shares") exceeds the
Closing Sale Price per share of Common Stock on the first Trading Day immediately succeeding the last date (such last date, the "Expiration Date") on
which tenders or exchanges could have been made pursuant to such tender offer or exchange offer (as the same may be amended through the Expiration Date), then the Conversion Rate shall be increased by
multiplying the Conversion Rate in effect immediately prior to the opening of business on the Business Day immediately following the first Trading Day immediately succeeding the Expiration Date by a
fraction (A) whose numerator is equal to the sum of (I) the Aggregate Amount and (II) the product of (a) the Closing Sale Price per share of Common Stock on the first
Trading Day immediately succeeding the Expiration Date and (b) an amount equal to (i) the number of shares of Common Stock outstanding as of the last time (the
"Expiration Time") at which tenders or exchanges could have been made pursuant to such tender offer or exchange offer (including all Purchased Shares)
less (ii) the Purchased Shares and (B) whose denominator is equal to the product of (I) the number of shares of Common Stock outstanding as of the Expiration Time (including all
Purchased Shares) and (II) the Closing Sale Price per share of Common Stock on the first Trading Day immediately succeeding the Expiration Date. 

        An
increase, if any, to the Conversion Rate pursuant to this Section 10.05(e) shall become effective at the opening of business on the Business Day immediately following the first
Trading 

46

 

Day
immediately succeeding the Expiration Date. In the event that the Company or a Subsidiary is obligated to purchase shares of Common Stock pursuant to any such tender offer or exchange offer, but
the Company or such Subsidiary is permanently prevented by applicable law from effecting any such purchases, or all such purchases are rescinded, then the Conversion Rate shall again be adjusted to be
the Conversion Rate which would then be in effect if such tender offer or exchange offer had not been made. If the application of this Section 10.05(e) to any tender offer or exchange offer
would result in a decrease in the Conversion Rate, no adjustment shall be made for such tender offer or exchange offer under this Section 10.05(e). 

        (f)    In
addition to the foregoing adjustments in subsections (a), (b), (c), (d) and (e) above, the Company, from time to time and to the extent permitted by law
and the continued listing requirements of the Nasdaq Global Select Market, may increase the Conversion Rate by any amount for a period of at
least twenty (20) calendar days or such longer period as may be permitted by law, if the Board of Directors has made a determination, which determination shall be conclusive, that such increase
would be in the best interests of the Company. Such Conversion Rate increase shall be irrevocable during such period. The Company shall give notice to the Trustee and the Conversion Agent and shall
mail notice of such increase to each Holder of Securities at such Holder's address as the same appears on the registry books of the Registrar, at least fifteen (15) days prior to the date on
which such increase commences. 

        (g)   For
the purpose of any computation under subsections (b), (c) or (d) above of this Section 10.05, the current market price per share of Common Stock
(the "Current Market Price") on any date (the "Determination Date") shall be deemed to be the average of
the Closing Sale Prices for the ten (10) consecutive Trading Days ending on, and including, the earlier of the Determination Date and the Ex-Date with respect to the distribution
requiring such computation; provided, however, that such Current Market Price per share of Common Stock shall be appropriately adjusted by the Board of
Directors, in its good faith determination (which determination shall be described in a Board Resolution), to account for any adjustment, pursuant hereto, to the Conversion Rate that shall become
effective, or any event requiring, pursuant hereto, an adjustment to the Conversion Rate where the Ex-Date of such event occurs, at any time during the period that begins on, and includes,
the first day of such ten (10) consecutive Trading Days and ends on, and includes, the date when the adjustment to the Conversion Rate on account of the event requiring the computation of such
Current Market Price becomes effective. 

        The
term "Ex-Date," (i) when used with respect to any issuance or distribution, means the first date on which the
Common Stock trades the regular way on the relevant exchange or in the relevant market from which the Closing Sale Price was obtained without the right to receive such issuance or distribution,
(ii) when used with respect to any subdivision or combination of shares of Common Stock, means the first date on which the Common Stock trades the regular way on such exchange or in such market
after the time at which such subdivision or combination becomes effective, and (iii) when used with respect to any tender offer or exchange offer means the first date on which the Common Stock
trades the regular way on such exchange or in such market after the expiration time of such tender offer or exchange offer (as it may be amended or extended). 

        Section 10.06
No Adjustment. 

        Notwithstanding
anything to the contrary in Section 10.05, no adjustment in the Conversion Rate pursuant to Section 10.05 shall be required until cumulative adjustments
amount to one percent (1%) or more of the Conversion Rate as last adjusted (or, if never adjusted, the initial Conversion Rate); provided, however, that
any adjustments to the Conversion Rate which by reason of this Section 10.06 are not required to be made shall be carried forward and taken into account in any subsequent adjustment to the
Conversion Rate; provided further, that if the Company shall mail a notice of Redemption pursuant to Section 3.04, or if a Fundamental Change or
Make-Whole Fundamental 

47

 

Change
occurs, or if the Securities shall become convertible pursuant to Section 10.01(a)(iv) or Section 10.01(a)(v), then, in each case, any adjustments to the Conversion Rate
that have been, and at such time remain, deferred pursuant to this Section 10.06 shall be given effect, and such adjustments, if any, shall no longer be carried forward and taken into account
in any subsequent adjustment to the Conversion Rate; provided, further, that the Company shall make such carried forward adjustments regardless of
whether the aggregate adjustment is less than 1% within one year of the first such adjustment carried forward, and on the Maturity Date. All calculations under this Article X shall be made to
the nearest cent or to the nearest one-millionth of a share, as the case may be. 

        Rights,
options or warrants distributed by the Company that until the occurrence of a specified event or events ("Trigger Event"):
(i) are deemed to be transferred with such shares of Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of Common Stock, shall be
deemed not to have been distributed for purposes of this Section 10.05 (and no adjustment to the Conversion Rate under this Section 10.05 will be required) until the occurrence of the
earliest Trigger Event, whereupon such rights, options and warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion Rate shall be made
under Section 10.05(c). Upon the expiration, termination or redemption of any such rights, options or warrants without the exercise of such rights, options or warrants, the Conversion Rate then
in effect shall be adjusted immediately to the Conversion Rate that would have been in effect at the time of such expiration, termination or redemption had such rights, options or warrants, to the
extent outstanding immediately prior to such expiration, termination or redemption, never been issued. 

        If
any dividend or distribution is declared and the Conversion Rate is adjusted pursuant to Section 10.05 on account of such dividend or distribution, but such dividend or
distribution is thereafter not paid or made, the Conversion Rate shall again be adjusted to the Conversion Rate which would then be in effect had such dividend or distribution not been declared. 

        No
adjustment to the Conversion Rate in connection with an transaction described in Sections 10.05(a) through 10.05(e) if the Company makes provision for each Holder of Securities to
participate in the transaction without conversion at the same time as holders of the Common Stock as if each such Holder of Securities held a number of shares of Common Stock equal to the Conversion
Rate in effect on the Ex-Date or effective date, as the case may be, for such transaction multiplied by the principal amount (expressed in
thousands) of Securities held by such Holder. 

        Notwithstanding
anything to the contrary herein, the Conversion Rate will not be increased, including pursuant to the provisions set forth in Section 10.14, to the extent that the
resulting increase will cause the Conversion Rate to exceed [            ] shares per $1,000 principal amount of Securities (the "Adjustment
Cap"). The Adjustment Cap shall be adjusted in the same manner in which, and for the same events for which, the Conversion Rate is adjusted under this Indenture. 

        Section 10.07
Other Adjustments. 

        In
the event that, as a result of an adjustment made pursuant to Section 10.05 hereof, the Holder of any Security thereafter surrendered for conversion shall become entitled to
receive any shares of Capital Stock other than shares of Common Stock, thereafter such other shares so receivable upon conversion of any Security shall be subject to adjustment, including the
Conversion Rate with respect thereto, from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to Common Stock contained in this Article X. 

        Section 10.08
Adjustments for Tax Purposes. 

        Except
as prohibited by law the Company may (but is not obligated to) make such increases in the Conversion Rate, in addition to those required by Section 10.05 hereof, as it
determines to be advisable in order that any Common Stock dividend, subdivision of shares of Common Stock, distribution of rights to purchase Common Stock or securities or distribution of securities
convertible into or 

48

 

exchangeable
for Common Stock made by the Company or to its stockholders will not be taxable to the recipients thereof or in order to diminish any such taxation. 

        Section 10.09
Notice of Adjustment. 

        Whenever
the Conversion Rate is adjusted, the Company shall promptly mail to Holders at the addresses appearing on the Registrar's books a notice of the adjustment and file with the
Trustee and the Conversion Agent an Officer's Certificate briefly stating the facts requiring the adjustment and the manner of computing it. The certificate shall be conclusive evidence of the
correctness of such adjustment. 

        Section 10.10
Notice of Certain Transactions. 

        In
the event that: 

        (1)   the
Company takes any action, or becomes aware of any event, which would require an adjustment in the Conversion Rate, 

        (2)   the
Company takes any action that would require a supplemental indenture pursuant to Section 10.11, or 

        (3)   there
is a dissolution or liquidation of the Company, 

the
Company shall mail to Holders at the addresses appearing on the Registrar's books, and the Trustee and the Conversion Agent, a written notice stating the proposed record, effective or expiration
date, as the case may be, of any transaction referred to in clause (1), (2) or (3) of this Section 10.10. The Company shall mail such notice at least twenty thirty
(30) Business Days before such date provided, however, failure to mail such notice or any defect therein shall not affect the validity of any
transaction referred to in clause (1), (2) or (3) of this Section 10.10. 

        Section 10.11
Effect of Reclassifications, Consolidations, Mergers, Binding Share Exchanges or Sales on Conversion Privilege. 

        Except
as provided in Section 10.14(e), if any of the following shall occur, namely: (i) any reclassification or change in the Common Stock issuable upon conversion of
Securities (other than a change only in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination of Common Stock),
(ii) any consolidation, merger or binding share exchange to which the Company is a party other than a merger in which the Company is the continuing Person and which does not result in any
reclassification of, or change (other than a change in name, or par value, or from par value to no par value, or from no par value to par value or as a result of a subdivision or combination) in, the
Common Stock or (iii) any sale, transfer, lease, conveyance or other disposition of all or substantially all of the property or assets of the Company or consummation of a similar transaction,
in each case pursuant to which the Common Stock would be converted into or exchanged for, or would constitute solely the right to receive, cash, securities or other property, then the Company or such
successor or purchasing Person, as the case may be, shall execute and deliver to the Trustee a supplemental indenture in form reasonably satisfactory to the Trustee providing that, at and after the
effective time of such reclassification, change, consolidation, merger, binding share exchange, sale, transfer, lease, conveyance or disposition, the Holder of each Security then outstanding shall
have the right to convert such Security (if otherwise convertible pursuant to this Article X) into the kind and amount of cash, securities or other property (collectively,
"Reference Property") receivable upon such reclassification, change, consolidation, merger, binding share exchange, sale, transfer, lease, conveyance,
disposition or similar transaction by a holder of a number of shares of Common Stock equal to the product of the principal amount of such Security and the Conversion Rate in effect immediately prior
to such reclassification, change, consolidation, merger, binding share exchange, sale, transfer, lease, conveyance, disposition or similar transaction (assuming, if holders of Common Stock shall have
the opportunity to elect the form of consideration to receive pursuant to 

49

 

such
reclassification, change, consolidation, merger, binding share exchange, sale, transfer, lease, conveyance or disposition, that the Collective Election shall have been made with respect to such
election); provided, however, that at and after the effective time of such reclassification, change, consolidation, merger, binding share exchange,
sale, transfer, lease, conveyance or disposition, the Principal Return payable hereunder upon conversion of such Security shall continue to be payable in cash, the Daily Conversion Value and each
Daily Share Amount shall be calculated based on the fair value of the Reference Property instead of the VWAP Price per share of Common Stock and the Daily Share Amount shall be payable, at the
Company's option in cash, Reference Property or a combination thereof pursuant to the procedures set forth in Section 10.02(h). If holders of Common Stock shall have the opportunity to elect
(the "Collective Election") the form of consideration to receive pursuant to such reclassification, change, consolidation, merger, binding share
exchange, sale, transfer, lease, conveyance or disposition, then the Company shall make adequate provision to give Holders, treated as a single class, a reasonable opportunity to elect the form of
such consideration for purposes of determining the composition of the Reference Property referred to in the immediately preceding sentence, and once such election is made, such election shall apply to
all Holders after the effective time of such reclassification, change, consolidation, merger, binding share exchange, sale, transfer, lease, conveyance or disposition. Such Collective Election shall
be determined based on the weighted average of the elections made by Holders of the Securities who participate in such determination, shall be subject to any limitations to which all of the holders of
Common Stock are subject, such as pro rata reductions applicable to any portion of the consideration payable in such reclassification, change,
consolidation, merger, binding share exchange, sale, transfer, lease, conveyance or disposition, and shall be conducted in such a manner as to be completed by the close of business on the actual
effective date of such reclassification, change, consolidation, merger, binding share exchange, sale, transfer, lease, conveyance or disposition. The supplemental indenture referred to in the first
sentence of this paragraph shall provide for adjustments, including with respect to the Conversion Rate, which shall be as nearly equivalent as may be practicable to the adjustments provided for in
this Article X. The
foregoing, however, shall not in any way affect the right a Holder of a Security may otherwise have, pursuant to Section 10.05(c), Section 10.05(b) or Section 10.13, to receive
rights or warrants upon conversion of a Security. If, in the case of any such consolidation, merger, binding share exchange, sale, transfer, lease, conveyance or disposition, the stock or other
securities and property (including cash) receivable thereupon by a holder of Common Stock includes shares of stock or other securities and property of a Person other than the successor or purchasing
Person, as the case may be, in such consolidation, merger, binding share exchange, sale, transfer, lease, conveyance or disposition, then such supplemental indenture shall also be executed by such
other Person and shall contain such additional provisions to protect the interests of the Holders of the Securities as the Board of Directors in good faith shall reasonably determine necessary by
reason of the foregoing (which determination shall be described in a Board Resolution). The provisions of this Section 10.11 shall similarly apply to successive consolidations, mergers, binding
share exchanges, sales, transfers, leases, conveyances or dispositions. 

        In
the event the Company shall execute a supplemental indenture pursuant to this Section 10.11, the Company shall promptly file with the Trustee and the Conversion Agent an
Officer's Certificate briefly stating the reasons therefor, the kind or amount of shares of stock or securities or property (including cash) receivable by Holders of the Securities upon the conversion
of their Securities after any such reclassification, change, consolidation, merger, binding share exchange, sale, transfer, lease, conveyance or disposition and any adjustment to be made with respect
thereto. 

50

   
        Section 10.12 Disclaimer of the Trustee and the Conversion Agent. 

        Neither
of the Trustee nor the Conversion Agent shall have any duty to determine when an adjustment under this Article X should be made, how it should be made or what such
adjustment should be, but each may accept as conclusive evidence of the correctness of any such adjustment, and shall be protected in relying upon, the Officer's Certificate with respect thereto which
the Company is obligated to file with the Trustee and the Conversion Agent pursuant to Section 10.09 hereof. Neither of the Trustee nor the Conversion Agent makes any representation as to the
validity or value of any securities or assets issued upon conversion of Securities, and none of them shall be responsible for the failure by the Company to comply with any provisions of this
Article X. 

        Neither
of the Trustee nor the Conversion Agent shall be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture executed pursuant
to Section 10.11, but each of them may accept as conclusive evidence of the correctness thereof, and shall be protected in relying upon, an Opinion of Counsel and the Officer's Certificate with
respect thereto which the Company is obligated to file with the Trustee pursuant to Section 10.11 hereof. 

        Section 10.13
Rights Distributions Pursuant to Stockholders' Rights Plans. 

        Upon
conversion, the Holders of Securities shall also receive, to the extent they receive shares of Common Stock, the associated rights under the rights agreement, dated as of
August 6, 2002, between the Company and American Stock Transfer and Trust Co. or any future shareholder rights plan the Company may establish (a "Rights
Plan"), unless prior to such conversion, such rights have separated from the Common Stock, in which case upon such separation, the Conversion Rate shall be adjusted pursuant to
Section 10.05(c), subject to readjustment in the event of the expiration, termination or redemption of such rights. 

        Section 10.14
Increased Conversion Rate Applicable to Certain Notes Surrendered in Connection with Make-Whole Fundamental
Changes. 

        (a)   Notwithstanding
anything herein to the contrary, the Conversion Rate applicable to each Security that is surrendered for conversion, in accordance with this
Article X, at any time during the period (the "Make-Whole Conversion Period") that begins on, and includes, the date that is thirty
(30) Business Days prior to the date originally announced by the Company as the anticipated effective date of a Make-Whole Fundamental Change (which anticipated effective date the
Company shall disclose, in good faith, in the written notice, public announcement and publication referred to in Section 10.14(d)) and ends on, and includes, the date that is thirty
(30) Business Days after the actual effective date of such Make-Whole Fundamental Change (or, if such Make-Whole Fundamental Change also constitutes a Fundamental
Change, to, and including, the Fundamental Change Repurchase Date applicable to such Fundamental Change) shall be increased to an amount equal to the Conversion Rate that would, but for this
Section 10.14, otherwise apply to such Security pursuant to this Article X, plus an amount equal to the Make-Whole Applicable
Increase; provided, however, that such increase to the Conversion Rate shall not apply if either: 

          (i)  such
Make-Whole Fundamental Change constitutes a Public Acquirer Fundamental Change with respect to which the Company shall have duly made, and given full
effect to, an election, pursuant to and in accordance with Section 10.14(e), to make an Acquirer Stock Conversion Right Adjustment; or 

         (ii)  such
Make-Whole Fundamental Change is announced by the Company but shall not be consummated. 

        The
additional consideration payable hereunder on account of any Make-Whole Applicable Increase with respect to a Security surrendered for conversion is herein referred to as
the "Make-Whole Consideration." 

51

 

        (b)   As
used herein, "Make-Whole Applicable Increase" shall mean, with respect to a Make-Whole
Fundamental Change, the amount, set forth in the following table, which corresponds to the effective date of such Make-Whole Fundamental Change (the "Effective
Date") and the Applicable Price of such Make-Whole Fundamental Change:

provided, however, that: 

          (i)  if
the actual Applicable Price of such Make-Whole Fundamental Change is between two (2) Applicable Prices listed in the table above under the column
titled "Applicable Price," or if the actual Effective Date of such Make-Whole Fundamental Change is between two Effective Dates listed in the table above in the row immediately below the
title "Effective Date," then
the Make-Whole Applicable Increase for such Make-Whole Fundamental Change shall be determined by linear interpolation between the Make-Whole Applicable Increases
set forth for such two Applicable Prices, or for such two Effective Dates based on a three hundred and sixty five (365) day year, as applicable; 

         (ii)  if
the actual Applicable Price of such Make-Whole Fundamental Change is greater than $[    ] per share (the
"Make-Whole Cap") (subject to adjustment as provided in Section 10.14(b)(iii)), or if the actual Applicable Price of such
Make-Whole Fundamental Change is less than $[    ] (the "Make-Whole Floor") per share (subject
to adjustment as provided in Section 10.14(b)(iii)), then the Make-Whole Applicable Increase shall be equal to zero (0); 

        (iii)  if
an event occurs that requires, pursuant to this Article X (other than solely pursuant to this Section 10.14), an adjustment to the Conversion Rate,
then, on the date and at the time such adjustment is so required to be made, each price set forth in the table above under the column 

52

 

titled
"Applicable Price", as well as the Make-Whole Cap and Make-Whole Floo,r shall be deemed to be adjusted so that such price, at and after such time, shall be equal to the
product of (1) such price as in effect immediately before such adjustment to such price and (2) a fraction whose numerator is the Conversion Rate in effect immediately before such
adjustment to the Conversion Rate and whose denominator is the Conversion Rate to be in effect, in accordance with this Article X, immediately after such adjustment to the Conversion Rate; 

        (iv)  if
the Company is required to increase the Conversion Rate by the Make-Whole Applicable Increase as a result of a Make-Whole Fundamental Change,
Securities surrendered for conversion will be settled in accordance with the provisions of this Section 10.14(b)(iv) (subject in all respects to the provisions set forth in
Section 10.02). If the last day of the applicable Cash Settlement Averaging Period related to Securities surrendered for conversion is prior to the third scheduled Trading Day preceding the
anticipated effective date of such Make-Whole Fundamental Change, the Company will settle such conversion as set forth in Section 10.02 by delivering the amount of consideration
due, based on the Conversion Rate prior to adjustment for the Make-Whole Applicable Increase, on the third Trading Day immediately following the last day of the applicable Cash Settlement
Averaging Period. As soon as practicable following the Effective date of such Make-Whole Fundamental Change, the Company will deliver the Make-Whole Consideration in the form
of cash and shares of the Common Stock or Reference Property deliverable in lieu of shares of Common Stock, if any, as the case may be, as if the Conversion Rate had been increased by the
Make-Whole Applicable Increase during the related Cash Settlement Averaging Period (and based upon the relevant daily VWAP Prices during such Cash Settlement Averaging Period). If such
Make-Whole Applicable Increase results in an increase to the amount of cash to be paid to Holders, the Company will pay such Make-Whole Applicable Increase in cash, and if such
Make-Whole Applicable Increase results in an increase to the number of shares of Common Stock, the Company will deliver such increase by delivering shares of Common Stock or
Reference Property based on such Make-Whole Applicable Increase. If the last Trading Day of the applicable Cash Settlement Averaging Period related to Securities surrendered for conversion
is on or following the third scheduled Trading Day preceding the anticipated effective date of the Make-Whole Fundamental Change, the Company will settle such conversion as set forth in
Section 10.02 on the later to occur of (i) the Effective Date of the Make-Whole Fundamental Change and (ii) the third Trading Day immediately following the last
Trading Day of the applicable Cash Settlement Averaging Period. 

         (v)  each
Make-Whole Applicable Increase amount set forth in the table above shall be adjusted in the same manner in which, and for the same events for which, the
Conversion Rate is to be adjusted pursuant to Section 10.01 through Section 10.13; and 

        (c)   As
used herein, "Applicable Price" shall have the following meaning with respect to a Make-Whole Fundamental
Change: (I) if such Make-Whole Fundamental Change constitutes a Common Stock Change Make-Whole Fundamental Change and the consideration (excluding cash payments for
fractional shares or pursuant to statutory appraisal rights) for the Common Stock in such Make-Whole Fundamental Change consists solely of cash, then the "Applicable Price" with respect to
such Make-Whole Fundamental Change shall be equal to the cash amount paid per share of Common Stock in such Make-Whole Fundamental Change; and (II) in all other
circumstances, the "Applicable Price" with respect to such Make-Whole Fundamental Change shall be equal to the average of the Closing Sale Prices per share of Common Stock for the five
(5) consecutive Trading Days immediately preceding the Effective Date of such Make-Whole Fundamental Change, which average shall be appropriately adjusted by the Board of Directors,
in its good faith determination (which determination shall be described in a Board Resolution), to account for any adjustment, pursuant hereto, to the Conversion Rate that shall become effective, or
any event requiring, pursuant hereto, an adjustment to 

53

 

the
Conversion Rate where the Ex-Date of such event occurs, at any time during such five (5) consecutive Trading Days. 

        (d)   At
least thirty (30) Business Days before the first anticipated effective date of each proposed Make-Whole Fundamental Change, the Company shall mail
to each Holder, in accordance with Section 14.02, written notice of, and shall publicly announce, through a reputable national newswire service, and publish on the Company's website, the
anticipated effective date of such proposed Make-Whole Fundamental Change. Each such notice, announcement and publication shall also state (I) that the Company either (A) has
elected, in accordance with Section 10.14(e), to make an Acquirer Stock Conversion Right Adjustment with respect to such Make-Whole Fundamental Change in lieu of increasing the
Conversion Rate pursuant to Section 10.14(a) or (B) has elected not to make an Acquirer Stock Conversion Right Adjustment with respect to such Make-Whole Fundamental Change;
and (II) if the Company has elected not to make such Acquirer Stock Conversion Right Adjustment with respect to such Make-Whole Fundamental Change, that, in connection with such
Make-Whole Fundamental Change, the Company shall increase, in accordance herewith, the Conversion Rate applicable to Securities entitled as provided herein to such increase (along with a
description of how such increase shall be calculated and the time periods during which Securities must be surrendered in order to be entitled to such increase). No later than the third Business Day
after the Effective Date of each Make-Whole Fundamental Change, the Company shall mail, in accordance with Section 14.02, written notice of, and shall publicly announce, through a
reputable national newswire service, and publish on the Company's website, such Effective Date and the Make-Whole Applicable Increase applicable to such Make-Whole Fundamental
Change. 

        (e)   Notwithstanding
anything to the contrary in this Section 10.14, if the Company shall make any mailing, announcement or publication referred to in
Section 10.14(d) in respect of a Make-Whole Fundamental Change that shall also constitute a Public Acquirer Fundamental Change, then the Company shall have the right to, in lieu of
increasing the Conversion Rate pursuant to Section 10.14(a) in connection with such Make-Whole Fundamental Change, cause the right to convert the Securities in accordance with this
Article X to change such that, from and after the effective time of such Public Acquirer Fundamental Change, the Holder of each Security then outstanding shall have the right to convert such
Security (if otherwise convertible pursuant to this Article X) solely into shares of the Public Acquirer Common Stock applicable to such Public Acquirer Fundamental Change (except that, at and
after such effective time, the Principal Return payable hereunder upon conversion of such Security shall continue to be payable in cash, the Daily Conversion Value and each Daily Share Amount shall be
calculated by reference to the VWAP Price per share of such Public Acquirer Common Stock as opposed to the VWAP Price per share of the Common Stock and each Daily Share Amount shall be payable, at the
Company's option, in cash, Public Acquirer Common Stock (instead of Common Stock), or a combination thereof pursuant to the procedures set forth in Section 10.02(h)), at an initial Conversion
Rate (which shall take effect at such effective time, but which shall thereafter be subject to adjustment in the same manner in which, and for the same events for which, the Conversion Rate is to be
adjusted pursuant to this Article X) equal to the Conversion Rate in effect immediately before such effective time multiplied by a fraction (I) whose numerator is the fair market value
(as determined in good faith by the Board of Directors, which determination shall be described in a Board Resolution), as of such effective time of such Public Acquirer Fundamental Change, of the
cash, securities and other property paid or payable pursuant to such Public Acquirer Fundamental Change per share of Common Stock and (II) whose denominator is the average of the Closing Sale
Prices per share of such Public Acquirer Common Stock for the five (5) consecutive trading days commencing on, and including, the trading day immediately after the Effective Date of such Public
Acquirer Fundamental Change, which average shall be appropriately adjusted by the Board of Directors, in its good faith determination (which determination shall be described in a Board Resolution), to
account for any event that, assuming such Public Acquirer Common Stock were Common Stock, would require, pursuant hereto, an adjustment to the Conversion Rate to become effective, or any such event
whose 

54

 

Ex-Date
occurs, at any time during such five (5) consecutive trading days. Any such change in the right to convert the Securities in accordance with this Section 10.14(e) is
herein referred to as an "Acquirer Stock Conversion Right Adjustment." 

        If
the Company shall have elected, in accordance with this Section 10.14(e), to make an Acquirer Stock Conversion Right Adjustment with respect to a Public Acquirer Fundamental
Change, then: 

          (i)  the
Company shall cause there to be executed and delivered to the Trustee a supplemental indenture in form reasonably satisfactory to the Trustee, which supplemental
indenture shall (a) give due effect to such election in accordance with this Section 10.14(e), including, without limitation, evidencing a binding and enforceable obligation of the
issuer of the applicable Public Acquirer Common Stock to satisfy the right of Holders to convert Securities in accordance with this Article X and this Section 10.14(e); (b) be
executed by, without limitation, such issuer; (c) which supplemental indenture shall provide for such adjustments, including with respect to the Conversion Rate, and contain such additional
provisions to protect the interests of the Holders of the Securities, as the Board of Directors in good faith shall
reasonably determine (which determination shall be described in a Board Resolution); and (d) be in full force and effect no later than the effective time of such Public Acquirer Fundamental
Change; 

         (ii)  the
Company shall promptly file with the Trustee an Officer's Certificate briefly stating the reasons for such supplemental indenture, the nature of the change in the
conversion right pursuant to such Acquirer Stock Conversion Right Adjustment and the Conversion Rate as adjusted therefor; 

        (iii)  the
provisions of Section 10.11 shall not apply to such Public Acquirer Fundamental Change, provided such Public
Acquirer Fundamental Change shall have been duly given effect in accordance with this Section 10.14(e); and 

        (iv)  such
election shall be irrevocable with respect to such Public Acquirer Fundamental Change and shall be deemed to have been made at the time the Company shall, with
respect to such Public Acquirer Fundamental Change, mail the first notice, or make the first public announcement or publication, whichever shall occur earlier, referred to in Section 10.14(d)
(it being understood that the Company shall discharge its obligations hereunder in good faith in determining whether an announced transaction and a completed transaction are deemed, for purposes of
this clause (iv), to be the same Public Acquirer Fundamental Change despite differences in the announced terms and the terms as such transaction was consummated);  provided, however, that the
Company shall not be obligated to give effect to such an election with respect to a Public Acquirer Fundamental Change that
has been announced by the Company but that shall not be consummated. 

        For
avoidance of doubt, any change in the right of Holders, made pursuant to this Section 10.14(e), to convert Securities shall apply to all Holders. 

        (f)    For
avoidance of doubt, the provisions of this Section 10.14 shall not affect or diminish the Company's other obligations, if any, under this Indenture with
respect to a Public Acquirer Fundamental Change or Make-Whole Fundamental Change. 

        (g)   Nothing
in this Section 10.14 shall prevent an adjustment to the Conversion Rate pursuant to Section 10.05 in respect of a Make-Whole
Fundamental Change or a Public Acquirer Fundamental Change.

OF SECURITY] 

EARTHLINK, INC.  

[    ]% Convertible Senior Note due 2026  

        1.     Interest.  EarthLink, Inc., a Delaware corporation (the "Company"), promises to
pay interest on the principal amount of this Security at the rate per annum shown above. The Company will pay interest, payable semi-annually in arrears, on May 15 and
November 15 of each year, with the first payment to be made on May 15, 2007. Interest on the Securities will accrue on the principal amount from, and including, the most recent date to
which interest has been paid or provided for or, if no interest has been paid, from, and including, November [    ], 2006, in each case to, but excluding, the
next interest payment date or Maturity Date, as the case may be. Notwithstanding the foregoing, on the Maturity Date, the Company shall pay any accrued and unpaid interest to the Holder to whom it
pays the principal amount payable on the Maturity Date, instead of to the Holder of record on the record date corresponding to the interest payment that falls on the Maturity Date. Interest will be
computed on the basis of a 360-day year of twelve 30-day months. 

        2.     Maturity.  The Securities will mature on November 15, 2026. 

        3.     Method of Payment.  Except as provided in the Indenture (as defined below), the Company will pay interest on
the Securities to the persons who are Holders of record of Securities at the close of business on the record date set forth on the face of this Security next preceding the applicable interest payment
date. Holders must surrender Securities to a Paying Agent to collect the principal amount, Redemption Price, Option Purchase Price or Fundamental Change Repurchase Price of the Securities, plus, if
applicable, accrued and unpaid interest, if any, payable as herein provided upon Redemption, Purchase at Holder's Option or Repurchase Upon Fundamental Change, as the case may be. The Company will
pay, in money of the United States that at the time of payment is legal tender for payment of public and private debts, all amounts due in cash with respect to the Securities, which amounts shall be
paid (A) in the case this Security is a Global Security, by wire transfer of immediately available funds to the account designated by the Depositary or its nominee; (B) in the case this
Security is a Physical Security and is held by a Holder of more than five million dollars ($5,000,000) in aggregate principal amount of Securities, by wire transfer of immediately available funds to
the account within the United States of America specified by such Holder or, if such Holder does not specify an account, by mailing a check to the address of such Holder set forth in the register of
the Registrar; and (C) in the case this Security is a Physical Security and is held by a Holder of five million dollars ($5,000,000) or less in aggregate principal amount of Securities, by
mailing a check to the address of such Holder set forth in the register of the Registrar. If a payment date is a Legal Holiday at a place of payment, payment may be made at that place on the next
succeeding day that is not a Legal Holiday, and no interest shall accrue on that payment for the additional period of time. 

        4.     Paying Agent, Registrar, Conversion Agent.  Initially, Wells Fargo Bank, N.A. (the
"Trustee") will act as Paying Agent, Registrar, Bid Solicitation Agent and Conversion Agent. The Company may change any Paying Agent, Registrar, Bid
Solicitation Agent or Conversion Agent without notice. 

        5.     Indenture. The Company issued the Securities under an Indenture dated as of
November [    ], 2006 (the "Indenture") between the Company and the Trustee. The terms of the Securities
include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S. Code §§ 77aaa-77bbbb)
(the "TIA") as amended and in effect from time to time. The Securities are subject to all such terms, and Holders are referred to the Indenture and the
TIA for a statement of such terms. The Securities are general unsecured senior subordinate obligations of the Company limited to $225,000,000 aggregate principal amount ($258,750,000 if the
Underwriters have elected to exercise in full the Option to purchase up to an additional $33,7500,000 aggregate principal amount of the Securities), except as otherwise provided in the Indenture
(except for Securities issued in 

A-3

 

substitution
for destroyed, mutilated, lost or stolen Securities). Terms used herein without definition and which are defined in the Indenture have the meanings assigned to them in the Indenture. 

        6.     Optional Redemption.  Subject to the terms and conditions of the Indenture, the Company shall have the right,
at the Company's option, at any time, and from time to time, on a Redemption Date on or after November 15, 2011, to redeem all or any part of the Securities. 

        7.     Notice of Redemption.  Notice of Redemption will be mailed at least thirty (30) calendar days but not
more than sixty (60) calendar days before the Redemption Date to each Holder of Securities to be redeemed at its address appearing in the security register. 

        8.     Purchase by the Company at the Option of the Holder.  Subject to the terms and conditions of the Indenture,
the Company shall become obligated to purchase, at the option of each Holder, the Securities held by such Holder on November 15, 2011, November 15, 2016 and November 15, 2021. 

        9.     Repurchase at Option of Holder Upon a Fundamental Change.  Subject to the terms and conditions of the
Indenture, in the event of a Fundamental Change, each Holder of the Securities shall have the right, at the Holder's option, to require the Company to repurchase such Holder's Securities including any
portion thereof which is $1,000 in principal amount or any integral multiple thereof. 

        10.   Conversion.  Subject to the terms and conditions of the Indenture, the Securities will be convertible into
cash or, at the Company's option, cash and shares of Common Stock based on an initial Conversion Rate, subject to adjustment, of [            ] shares per $1,000 principal
amount of Securities. 

        11.   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. The transfer of Securities may be registered and Securities may be exchanged as provided in the Indenture. The Trustee may
require a Holder, among other things, to furnish appropriate endorsements and transfer documents. No service charge shall be made for any such registration of transfer or exchange, but the Company and
the Trustee may require payment of a sum sufficient to cover any tax or similar governmental charge that may be imposed in connection with certain transfers or exchanges. The Company or the Trustee,
as the case may be, shall not be required to register the transfer of or exchange any Security (i) for a period of twenty (20) calendar days before selecting, pursuant to
Section 3.03 of the Indenture, Securities to be redeemed or (ii) that has been selected for Redemption or for which a Purchase Notice has been delivered pursuant to Section 3.08
or 3.09, and not withdrawn, in accordance with the Indenture, except, in the case of a partial redemption, purchase or repurchase, that portion of Securities not being redeemed or repurchased. 

        12.   Persons Deemed Owners.  The registered Holder of a Security may be treated as the owner of such Security for
all purposes. 

        13.   Merger or Consolidation.  Except as provided in the Indenture, the Company shall not consolidate with, or
merge with or into, or sell, transfer, lease, convey or otherwise dispose of all or substantially all of the property or assets of the Company to, another person, whether in a single transaction or
series of related transactions. 

        14.   Amendments, Supplements and Waivers.  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 outstanding Securities, and certain existing Defaults or Events of Default may be
waived with the consent of the Holders of a majority in aggregate principal amount of the Securities then outstanding. In accordance with the terms of the Indenture, the Company, with the consent of
the Trustee, may amend or supplement certain provisions of the Indenture or the Securities without notice to or the consent of any Securityholder. 

A-4

 

        15.   Defaults and Remedies.  If an Event of Default (excluding an Event of Default specified in
Section 6.01(viii) or (ix) of the Indenture with respect to the Company (but including an Event of Default specified in Section 6.01(viii) or (ix) of the
Indenture solely with respect to a Significant Subsidiary of the Company or any group of Subsidiaries that in the aggregate would constitute a Significant Subsidiary of the Company)) occurs and is
continuing, the Trustee by notice to the Company or the Holders of at least twenty five percent (25%) in principal amount of the Securities then outstanding by notice to the Company and the Trustee
may declare the Securities to be due and payable. If an Event of Default specified in Section 6.01(viii) or (ix) of the Indenture with respect to the Company (excluding, for
purposes of this sentence, an Event of Default specified in Section 6.01(viii) or (ix) of the Indenture solely with respect to a Significant Subsidiary of the Company or any group
of Subsidiaries that in the aggregate would constitute a Significant Subsidiary of the Company) occurs, the principal of, and premium and accrued and unpaid interest on, all the Securities shall ipso
facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder.

successor Trustee thereunder, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for, the Company or its Affiliates, and may otherwise deal with the
Company or its Affiliates, as if it were not Trustee. 

        17.   No Recourse Against Others.  No past, present or future director, officer, employee or shareholder, as such,
of the Company shall have any liability for any obligations of the Company under the Securities or the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their
creation. Each Holder, by accepting a Security, waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Securities. 

        18.   Authentication.  This Security shall not be valid until authenticated by the manual signature of the Trustee
or an authenticating agent in accordance with the Indenture. 

        19.   Governing Law.  The laws of the State of New York, without regard to principles of conflicts of law, shall
govern the Securities.
