as of the Closing. 

  

	1.2	Purchase Price. In consideration for Sellers’ delivery of the Membership Interests, Purchaser shall issue to Sellers at the Closing 3,913,034 fully paid ordinary shares
in the Purchaser (“Shares”). The Purchase Price for Membership Interests has been established and will be allocated among the Sellers as set forth in Schedule 1.2. 

  

	1.3	Purchase of Notes. Subject to the terms and conditions set forth herein, McAllister will assign to Purchaser his rights under the Promissory Notes held by McAllister, and
issued by the Company, copies of which are attached hereto as Schedule 1.3.

	1.5	Purchaser’s Common Stock. Sellers and McAllister agree that the Shares issued to them by the Purchaser, pursuant to Sections 1.2 and 1.4 respectively (the
“Consideration Shares”), will not be, directly or indirectly, sold, pledged, transferred, or otherwise disposed of; except that Sellers or McAllister may each, individually, sell an amount of such Consideration Shares, in each calendar
quarter, commencing during the first quarter of 2004, equal to the greater of (i) the number of such Consideration Shares required to fund any U.S. income taxes owed by them individually as a direct result of the transaction contemplated by this

reorganization, merger, consolidation, recapitalization, reclassification, stock split-up, combination of shares, or dividend payable in shares, the parties shall make an appropriate adjustment to the number and kind of shares constituting the

or other action provided by this Indenture to be given or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by an agent duly appointed in writing; and,
except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee and, where it is hereby expressly required, to the Company, as described in Section 12.02. Such
instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of Holders signing such instrument or instruments. Proof of execution of any such instrument or of a

 (b) The fact and date of the execution by any person of any such instrument
or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing
acknowledged to such officer the execution thereof. Where such execution is by a signer acting in a capacity other than such signer’s individual capacity, such certificate or affidavit shall also constitute sufficient proof of such

therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee or the Company in reliance thereon, whether or not notation of such action is made upon such Security. 
  
 (e) If the Company shall solicit from the Holders any request, demand,
authorization, direction, notice, consent, waiver or other Act, the Company may, at its option, by or pursuant to a Board Resolution, fix in advance a record date for the determination of Holders entitled to give such request, demand, authorization,
direction, notice, consent, waiver or other Act, but the Company shall have no obligation to do so. If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other Act may be given before or after
such record date, but only the Holders of record at the close of business on such record date shall be deemed to be Holders for the purposes of determining whether Holders of the requisite proportion of outstanding Securities have authorized or
agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other Act, and for that purpose the outstanding Securities shall be computed as of such record date; provided that no such authorization,
agreement or consent by the Holders on such record date shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later than six months after the record date. 
  
 ARTICLE 2 
 THE SECURITIES 
  
 Section 2.01. Form and Dating. The Securities and the Trustee’s certificate of authentication shall be substantially in the form of Exhibits A
and B, which are a part of this Indenture. The Securities may have notations, legends or endorsements required by law, stock exchange rule or usage (provided that any such notation, legend or endorsement required by usage is in a form
acceptable to the Company). The Company shall provide any such notations, legends or endorsements to the Trustee in writing. Each Security shall be dated the date of its authentication. 
  
 (a) 144A Global Securities. Securities offered and sold within the United States to qualified institutional buyers as
defined in Rule 144A (“QIBs”) in reliance on Rule 144A shall be issued, initially in the form of a 144A Global Security, which shall be deposited with the Trustee at its Corporate Trust Office, as custodian for the Depositary (as
defined below) and registered in the name of The Depository Trust Company (“DTC”) or the nominee thereof (DTC, or any successor thereto, and any such nominee being hereinafter referred to as the “Depositary”), duly
executed by the Company and authenticated by the Trustee as hereinafter provided. The aggregate principal amount of the 144A Global Securities may from time to time be increased or decreased by adjustments made on the records of the Trustee and the
Depositary as hereinafter provided. 
  

 11 

 (b) Global Securities in General. Each Global Security shall represent such of the outstanding
Securities as shall be specified therein and each shall provide that it shall represent the aggregate amount of outstanding Securities from time to time endorsed thereon and that the aggregate amount of outstanding Securities represented thereby may
from time to time be reduced or increased, as appropriate, to reflect exchanges, redemptions, repurchases and conversions. 
  
 Any adjustment of the aggregate principal amount of a Global Security to reflect the amount of any increase or decrease in the amount of outstanding
Securities represented thereby shall be made by the Trustee in accordance with instructions given by the Holder thereof as required by Section 2.12 hereof and shall be made on the records of the Trustee and the Depositary. 
  
 (c) Book-Entry Provisions. This Section 2.01(c) shall apply only to
Global Securities deposited with or on behalf of the Depositary. 
  
 The Company shall execute and the Trustee shall, in accordance with this Section 2.01(c), authenticate and deliver initially one or more Global Securities that (a) shall be registered in the name of the Depositary, (b) shall be delivered by
the Trustee to the Depositary or held by the Trustee pursuant to the Depositary’s instructions and (c) shall be substantially in the form of Exhibit A attached hereto. 
  
 (d) Certificated Securities. Securities not issued as interests in the Global Securities will be issued in
certificated form substantially in the form of Exhibit B attached hereto. 
  
 Section 2.02. Execution and Authentication. The Securities shall be executed on behalf of the Company by two Officers. The signature of the two Officers on the Securities may be manual or facsimile. 

 
 Securities bearing the manual or facsimile signatures of individuals who
were, at the time of the execution of the Securities, Officers shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Securities or did not hold
such offices at the date of authentication of such Securities. 
  
 No Security shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Security a certificate of authentication substantially in the form provided for herein duly executed by
the Trustee by manual signature of an authorized signatory, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder. 
  
 The Trustee shall authenticate and deliver the Securities for original issue
in an aggregate principal amount of up to $75,000,000 (up to $82,500,000 aggregate principal amount if the initial purchasers’ option set forth in the Purchase Agreement is exercised in full) upon one or more Company Orders 
  

 12 

 without any further action by the Company (other than as contemplated in Section 12.04 and Section 12.05 hereof). The
aggregate principal amount of the Securities due at the Stated Maturity thereof outstanding at any time may not exceed the amount set forth in the foregoing sentence. 
  
 The Securities shall be issued only in registered form without coupons and only in denominations of $1,000 of principal
amount and any integral multiple of $1,000. 
  
 Section 2.03.
Registrar, Paying Agent and Conversion Agent. The Company shall maintain an office or agency where Securities may be presented for registration of transfer or for exchange (“Registrar”), an office or agency where Securities may
be presented for purchase or payment (“Paying Agent”) and an office or agency 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 have one or more co-registrars, one or more additional paying agents and one or more additional conversion agents. The term Paying Agent includes any additional paying agent, including any named pursuant to
Section 4.05. The term Conversion Agent includes any additional conversion agent, including any named pursuant to Section 4.05. 
  
 The Company shall enter into an appropriate agency agreement with any Registrar, Paying Agent, Conversion Agent, or co-registrar (in each case, if such
Registrar, agent or co-registrar is a Person other than the Trustee). The agreement shall implement the provisions of this Indenture that relate to such agent. The Company shall notify the Trustee of the name and address of any such agent. If the
Company fails to maintain a Registrar, Paying Agent or Conversion Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefor pursuant to Section 7.07. The Company or any Subsidiary or an Affiliate of either of
them may act as Paying Agent, Registrar, Conversion Agent or co-registrar. 
  
 The Company initially appoints the Trustee as Registrar, Conversion Agent and Paying Agent in connection with the Securities. 
  
 Section 2.04. Paying Agent to Hold Money and Securities in Trust. Except as otherwise provided herein, on or prior to each due date of payments in
respect of any Security, the Company shall deposit with the Paying Agent a sum of money (in immediately available funds if deposited on the due date) or shares of Common Stock sufficient to make such payments when so becoming due. The Company shall
require each Paying Agent (other than the Trustee) to agree in writing that the Paying Agent shall hold in trust for the benefit of Securityholders or the Trustee all money and shares of Common Stock held by the Paying Agent for the making of
payments in respect of the Securities and shall notify the Trustee of any default by the Company in making any such payment. At any time during the continuance of any such default, the Paying Agent shall, upon the written request of the Trustee,
forthwith pay to the Trustee all money and shares 
  

 13 

 of Common Stock so held in trust. If the Company, a Subsidiary or an Affiliate of either of them acts as Paying Agent, it
shall segregate the money and shares of Common Stock held by it as Paying Agent and hold it as a separate trust fund. The Company at any time may require a Paying Agent to pay all money and shares of Common Stock held by it to the Trustee and to
account for any funds and Common Stock disbursed by it. Upon doing so, the Paying Agent shall have no further liability for the money or shares of Common Stock. 
  

Section 2.05. Securityholder Lists. The Trustee shall preserve the most recent list available to it of the names and addresses of
Securityholders. If the Trustee is not the Registrar, the Company shall cause to be furnished to the Trustee at least semiannually on July 1 and January 1 a listing of Securityholders dated within 15 days of the date on which the list is furnished
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. 
  
 Section 2.06. Transfer and Exchange. 
  
 (a) Subject to Section 2.12 hereof, upon surrender for registration of transfer of any Security, together with a written
instrument of transfer satisfactory to the Registrar duly executed by the Securityholder or such Securityholder’s attorney duly authorized in writing, at the office or agency of the Company designated as Registrar or co-registrar pursuant to
Section 2.03, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Securities of any authorized denomination or denominations, of a like aggregate
principal amount. The Company shall not charge a service charge for any registration of transfer or exchange, but the Company may require payment of a sum sufficient to pay all taxes, assessments or other governmental charges that may be imposed in
connection with the transfer or exchange of the Securities from the Securityholder requesting such transfer or exchange. 
  
 At the option of the Holder, Securities may be exchanged for other Securities of any authorized denomination or denominations, of a like aggregate
principal amount upon surrender of the Securities to be exchanged, together with a written instrument of transfer satisfactory to the Registrar duly executed by the Securityholder or such Securityholder’s attorney duly authorized in writing, at
such office or agency. Whenever any Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive. 
  
 The Company shall not be required to make, and the Registrar need not
register, transfers or exchanges of Securities selected for redemption (except, in the case of Securities to be redeemed in part, the portion thereof not to be redeemed) or any Securities in respect of which a Repurchase Notice or Change of Control
Repurchase Notice has been given and not withdrawn by the Holder 
  

 14 

 thereof in accordance with the terms of this Indenture (except, in the case of Securities to be purchased in part, the
portion thereof not to be purchased) or any Securities for a period of 15 days before the mailing of a notice of redemption of Securities to be redeemed. 
  
 (b) Notwithstanding any provision to the contrary herein, so long as a Global Security remains outstanding and is held by or on behalf of the Depositary,
transfers of a Global Security, in whole or in part, shall be made only in accordance with Section 2.12 and this Section 2.06(b). Transfers of a Global Security shall be limited to transfers of such Global Security in whole or in part, to the
Depositary, to nominees of the Depositary or to a successor of the Depositary or such successor’s nominee. 
  
 (c) Successive registrations and registrations of transfers and exchanges as aforesaid may be made from time to time as desired, and each such
registration shall be noted on the register for the Securities. 
  
 (d) Any Registrar appointed pursuant to Section 2.03 hereof shall provide to the Trustee such information as the Trustee may reasonably require in connection with the delivery by such Registrar of Securities upon transfer or exchange of
Securities. 
  
 (e) No Registrar shall be required to make
registrations of transfer or exchange of Securities during any periods designated in the text of the Securities or in this Indenture as periods during which such registration of transfers and exchanges need not be made. 
  
 (f) If Securities are issued upon the transfer, exchange or replacement of
Securities subject to restrictions on transfer and bearing the legends set forth on the forms of Security attached hereto as Exhibits A and B setting forth such restrictions (collectively, the “Legend”), or if a request is made to
remove the Legend on a Security, the Securities so issued shall bear the Legend, or the Legend shall not be removed, as the case may be, unless there is delivered to each of the Company and the Trustee, and the Registrar (if not the same Person as
the Trustee) such satisfactory evidence, which shall include an opinion of counsel, as may be reasonably required by the Company and the Trustee (if not the same Person as the Trustee), that neither the Legend nor the restrictions on transfer set
forth therein are required to ensure that transfers thereof comply with the provisions of Rule 144A or Rule 144 under the Securities Act or that such Securities are not “restricted” within the meaning of Rule 144 under the
Securities Act. Upon (i) provision of such satisfactory evidence, or (ii) notification by the Company to the Trustee and Registrar of the sale of such Security pursuant to a registration statement that is effective at the time of such sale, the
Trustee, at the written direction of the Company, shall authenticate and deliver a Security that does not bear the Legend. If the Legend is removed from the face of a Security and the Security is subsequently held by the Company or an Affiliate of
the Company, the Legend shall be reinstated. 
  

 15 

 Section 2.07. Replacement Securities. If (a) any mutilated Security is surrendered to the Trustee,
or (b) the Company and the Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Security, and there is delivered to the Company and the Trustee such security or indemnity as may be required by them to save each of
them harmless, then, in the absence of notice to the Company or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute and upon its written request the Trustee shall authenticate and deliver, in exchange
for any such mutilated Security or in lieu of any such destroyed, lost or stolen Security, a new Security of like tenor and principal amount, bearing a certificate number not contemporaneously outstanding. 
  
 In case any such mutilated, destroyed, lost or stolen Security has become or
is about to become due and payable, or is about to be purchased by the Company pursuant to Article 3 hereof, the Company in its discretion may, instead of issuing a new Security, pay or purchase such Security, as the case may be. 
  
 Upon the issuance of any new Securities under this Section 2.07, the Company
may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith. 
  
 Every new Security issued pursuant to this Section 2.07 in lieu of any
mutilated, destroyed, lost or stolen Security shall constitute an original contractual obligation of the Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all benefits
of this Indenture equally and proportionately with any and all other Securities duly issued hereunder. 
  
 The provisions of this Section 2.07 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Securities. 
  
 Section 2.08. Outstanding Securities; Determinations of Holders’ Action. Securities outstanding at any time are all the Securities authenticated by the Trustee except for those cancelled by it, those paid pursuant to Section
2.07, those delivered to it for cancellation and those described in this Section 2.08 as not outstanding. A Security does not cease to be outstanding because the Company or an Affiliate thereof holds the Security; provided, however, that in
determining whether the Holders of the requisite principal amount of Securities have given or concurred in any request, demand, authorization, direction, notice, consent, waiver, or other Act hereunder, Securities owned by the Company or any other
obligor upon the Securities or any Affiliate of the Company or such other obligor shall be disregarded and deemed not to be outstanding, except that, in determining whether the Trustee shall be protected in relying upon any such request, demand,
authorization, direction, notice, consent, waiver or other act, only Securities which a Responsible Officer of the Trustee actually knows to be so owned shall 
  

 16 

 be so disregarded. Subject to the foregoing, only Securities outstanding at the time of such determination shall be
considered in any such determination (including, without limitation, determinations pursuant to Articles 6 and 9). 
  
 If a Security is replaced pursuant to Section 2.07, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced
Security is held by a bona fide purchaser. 
  
 If the Paying Agent
holds, in accordance with this Indenture, on a Redemption Date, or on the Business Day immediately following a Repurchase Date or a Change of Control Repurchase Date, or on Stated Maturity, money or securities, if permitted hereunder, sufficient to
pay Securities payable on that date, then immediately after such Redemption Date, Repurchase Date, Change of Control Repurchase Date or Stated Maturity, as the case may be, such Securities shall cease to be outstanding and Interest and Liquidated
Damages, if any, on such Securities shall cease to accrue; provided, that if such Securities are to be redeemed, notice of such redemption has been duly given pursuant to this Indenture or provision therefor satisfactory to the Trustee has
been made. 
  
 If a Security is converted in accordance with
Article 10, then from and after the time of conversion on the date of conversion, such Security shall cease to be outstanding and Interest and Liquidated Damages, if any, shall cease to accrue on such Security. 
  
 Section 2.09. Temporary Securities. Pending the preparation of
definitive Securities, the Company may execute, and upon Company Order the Trustee shall authenticate and deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Securities in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the Officers executing such Securities may determine, as conclusively
evidenced by their execution of such Securities. 
  
 If temporary
Securities are issued, the Company will cause definitive Securities to be prepared without unreasonable delay. After the preparation of definitive Securities, the temporary Securities shall be exchangeable for definitive Securities upon surrender of
the temporary Securities at the office or agency of the Company designated for such purpose pursuant to Section 2.03, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities the Company shall execute and
the Trustee shall authenticate and deliver in exchange therefor a like principal amount of definitive Securities of authorized denominations. Until so exchanged the temporary Securities shall in all respects be entitled to the same benefits under
this Indenture as definitive Securities. 
  
 Section 2.10.
Cancellation. All Securities surrendered for payment, purchase by the Company pursuant to Article 3, conversion, redemption or 
  

 17 

 registration of transfer or exchange shall, if surrendered to any person other than the Trustee, the Registrar or the
Paying Agent, as the case may be, be delivered to the Trustee and shall be promptly cancelled by it. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the
Company may have acquired in any manner whatsoever, and all Securities so delivered shall be promptly cancelled by the Trustee. The Company may not issue new Securities to replace Securities it has paid or delivered to the Trustee for cancellation
or that any Holder has converted pursuant to Article 10. No Securities shall be authenticated in lieu of or in exchange for any Securities cancelled as provided in this Section, except as expressly permitted by this Indenture. All cancelled
Securities held by the Trustee shall be disposed of by the Trustee in accordance with the Trustee’s customary procedure. 
  
 Section 2.11. Persons Deemed Owners. Prior to due presentment of a Security for registration of transfer, the Company, the Trustee and any agent of
the Company or the Trustee may treat the person in whose name such Security is registered as the owner of such Security for the purpose of receiving payment of the principal amount of the Security or any portion thereof, or the payment of any
Redemption Price, Repurchase Price or Change of Control Repurchase Price in respect thereof, and Interest or Liquidated Damages thereon, for the purpose of conversion and for all other purposes whatsoever, whether or not such Security be overdue,
and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary. 
  
 Section 2.12. Global Securities. 
  
 (a) Notwithstanding any other provisions of this Indenture or the Securities, (A) transfers of a Global Security, in whole or in part, shall be made only
in accordance with Section 2.06 and Section 2.12(a)(i), (B) transfers of a beneficial interest in a Global Security for a Certificated Security shall comply with Section 2.06, Section 2.12(a)(ii) and Section 2.12(e)(i), and (C) transfers of a
Certificated Security shall comply with Section 2.06, Section 2.12(a)(iii) and Section 2.12(a)(iv). 
  
 (i) Transfer of Global Security. A Global Security may not be transferred, in whole or in part, to any person other than the
Depositary or a nominee or any successor thereof, and no such transfer to any such other person may be registered; provided that this clause shall not prohibit any transfer of a Security that is issued in exchange for a Global Security but is
not itself a Global Security. No transfer of a Security to any Person shall be effective under this Indenture or the Securities unless and until such Security has been registered in the name of such Person. Nothing in this Section 2.12(a)(i) shall
prohibit or render ineffective any transfer of a beneficial interest in a Global Security effected in accordance with the other provisions of this Section 2.12(a). 
  

 18 

 (ii) Restrictions on Transfer of a Beneficial Interest in a Global Security for a
Certificated Security. A beneficial interest in a Global Security may not be exchanged for a Certificated Security except upon satisfaction of the requirements set forth below and in Section 2.12(e)(i) below. Upon receipt by the Trustee of a
transfer of a beneficial interest in a Global Security in accordance with Applicable Procedures for a Certificated Security in the form satisfactory to the Trustee, together with: 
  
 (A) so long as the Securities are Restricted Securities, certification in the form set forth in
Exhibit C; 
  
 (B) written instructions to
the Trustee to make, or direct the Registrar to make, an adjustment on its books and records with respect to such Global Security to reflect a decrease in the aggregate principal amount of the Securities represented by the Global Security, such
instructions to contain information regarding the Depositary account to be credited with such decrease; and 
  
 (C) if the Company or the Trustee so requests, an opinion of counsel or other evidence reasonably satisfactory to it as to the compliance
with the restrictions set forth in the Legend, 
  
 then the
Trustee shall cause, or direct the Registrar to cause, in accordance with the standing instructions and procedures existing between the Depositary and the Registrar, the aggregate principal amount of the Securities represented by the Global Security
to be decreased by the aggregate principal amount of the Certificated Security to be issued, shall issue such Certificated Security and shall debit or cause to be debited to the account of the person specified in such instructions a beneficial
interest in the Global Security equal to the principal amount of the Certificated Security so issued. 
  
 (iii) Transfer and Exchange of Certificated Securities. When Certificated Securities are presented to the Registrar with a request:

  
 (y) to register the transfer of such
Certificated Securities; or 
  
 (z) to exchange
such Certificated Securities for an equal principal amount of Certificated Securities of other authorized denominations, 
  
 the Registrar shall register the transfer or make the exchange as requested if its reasonable requirements for such transaction are met; provided,
however, that the Certificated Securities surrendered for transfer or exchange: 
  
 (A) shall be duly endorsed or accompanied by a written instrument of transfer in form reasonably satisfactory to the Company and the
Registrar, duly executed by the Holder thereof or his attorney duly authorized in writing; and 
  

 19 

 (B) so long as such Securities are Restricted Securities, such Securities are being
transferred or exchanged pursuant to an effective registration statement under the Securities Act or pursuant to clause (1), (2) or (3) below, and are accompanied by the following additional information and documents, as applicable: 
  
 (1) if such Certificated Securities are being delivered to
the Registrar by a Holder for registration in the name of such Holder, without transfer, a certification from such Holder to that effect; or 
  
 (2) if such Certificated Securities are being transferred to the Company, a certification to that effect; or 
  
 (3) if such Certificated Securities are being transferred
pursuant to an exemption from registration, (i) a certification to that effect (in the form set forth in Exhibit C, if applicable) and (ii) if the Company or the Trustee so requests, an opinion of counsel or other evidence reasonably satisfactory to
it as to the compliance with the restrictions set forth in the Legend. 
  
 (iv) Restrictions on Transfer of a Certificated Security for a Beneficial Interest in a Global Security. A Certificated Security may not be exchanged for a beneficial interest in a Global Security except upon
satisfaction of the requirements set forth below. 
  
 Upon receipt
by the Trustee of a Certificated Security, duly endorsed or accompanied by appropriate instruments of transfer, in form satisfactory to the Trustee, together with: 
  
 (A) so long as the Securities are Restricted Securities, certification, in the form set forth in Exhibit C,
that such Certificated Security (1) is being transferred to a QIB in accordance with Rule 144A under the Securities Act or (2) is being transferred pursuant to and in compliance with Rule 144 under the Securities Act; and 
  
 (B) written instructions directing the Trustee to make, or
to direct the Registrar to make, an adjustment on its books and records with respect to such Global Security to reflect an increase 
  

 20 

 in the aggregate principal amount of the Securities represented by the Global Security, such instructions
to contain information regarding the Depositary account to be credited with such increase, then the Trustee shall cancel such Certificated Security and cause, or direct the Registrar to cause, in accordance with the standing instructions and
procedures existing between the Depositary and the Registrar, the aggregate principal amount of Securities represented by the Global Security to be increased by the aggregate principal amount of the Certificated Security to be exchanged, and shall
credit or cause to be credited to the account of the person specified in such instructions a beneficial interest in the Global Security equal to the principal amount of the Certificated Security so cancelled. If no Global Securities are then
outstanding, the Company shall issue and the Trustee shall authenticate, upon written order of the Company in the form of an Officers’ Certificate, a new Global Security in the appropriate principal amount. 
  
 (b) Subject to Section 2.12(c), every Security shall be subject to the
restrictions on transfer provided in the Legend including the delivery of an opinion of counsel, if so provided. Whenever any Restricted Security is presented or surrendered for registration of transfer or for exchange for a Security registered in a
name other than that of the Holder, such Security must be accompanied by a certificate in substantially the form set forth in Exhibit C, dated the date of such surrender and signed by the Holder of such Security, as to compliance with such
restrictions on transfer. The Registrar shall not be required to accept for such registration of transfer or exchange any Security not so accompanied by a properly completed certificate. 
  
 (c) The restrictions imposed by the Legend upon the transferability of any Security shall cease and terminate when such
Security has been sold pursuant to an effective registration statement under the Securities Act or transferred in compliance with Rule 144 under the Securities Act (or any successor provision thereto) or, if earlier, upon the expiration of the
holding period applicable to sales thereof under Rule 144(k) under the Securities Act (or any successor provision). Any Security as to which such restrictions on transfer shall have expired in accordance with their terms or shall have terminated
may, upon a surrender of such Security for exchange to the Registrar in accordance with the provisions of this Section 2.12 (accompanied, in the event that such restrictions on transfer have terminated by reason of a transfer in compliance with Rule
144 or any successor provision, by an opinion of counsel having substantial experience in practice under the Securities Act and otherwise reasonably acceptable to the Company and the Trustee, addressed to the Company and the Trustee and in form
acceptable to the Company and the Trustee, to the effect that the transfer of such Security has been made in compliance with Rule 144 or such successor provision), be exchanged for a new Security, of like tenor and aggregate principal amount,

  

 21 

 which shall not bear the restrictive Legend. The Company shall inform the Trustee of the effective date of any
registration statement registering the Securities under the Securities Act. The Trustee shall not be liable for any action taken or omitted to be taken by it in good faith in accordance with the aforementioned opinion of counsel or registration
statement. 
  
 (d) As used in the preceding two paragraphs of this
Section 2.12, the term “transfer” encompasses any sale, pledge, transfer, loan, hypothecation, or other disposition of any Security. 
  
 (e) The provisions of clauses (i), (ii), (iii), (iv) and (v) of this Section 2.12(e) shall apply only to Global Securities: 
  
 (i) Notwithstanding any other provisions of this Indenture
or the Securities, a Global Security shall not be exchanged in whole or in part for a Security registered in the name of any Person other than the Depositary or one or more nominees thereof, provided that a Global Security may be exchanged
for Securities registered in the names of any person designated by the Depositary in the event that (A) the Depositary has notified the Company that it is unwilling or unable to continue as Depositary for such Global Security, and a successor
Depositary is not appointed by the Company within 90 days, (B) at any time, the Company, in its sole discretion but to the extent permitted by the Depositary, determines not to have Securities represented by Global Securities, or (C) upon a request
by or on behalf of the Depositary, a beneficial interest in a Global Security may be exchanged for a security in registered form in accordance with the Depositary’s procedures. Any Global Security exchanged pursuant to clause (A) above shall be
so exchanged in whole and not in part, and any Global Security exchanged pursuant to clause (B) above may be exchanged in whole or from time to time in part as directed by the Depositary. Any Security issued in exchange for a Global Security or any
portion thereof shall be a Global Security; provided that any such Security so issued that is registered in the name of a person other than the Depositary or a nominee thereof shall not be a Global Security. 
  
 (ii) Securities issued in exchange for a Global Security or
any portion thereof shall be issued in definitive, fully registered form, shall have an aggregate principal amount equal to that of such Global Security or portion thereof to be so exchanged, shall be registered in such names and be in such
authorized denominations as the Depositary shall designate and shall bear the applicable legends provided for herein. Any Global Security to be exchanged in whole shall be surrendered by the Depositary to the Registrar. With regard to any Global
Security to be exchanged in part, either such Global Security shall be so surrendered for exchange or, if the Trustee is acting as custodian for the Depositary or its nominee with respect to such Global Security, the principal amount thereof shall
be reduced, by an amount equal to the portion thereof to be so exchanged, by 
  

 22 

 means of an appropriate adjustment made on the records of the Trustee. Upon any such surrender or
adjustment, the Trustee shall authenticate and deliver the Security issuable on such exchange to or upon the order of the Depositary or an authorized representative thereof. 
  
 (iii) Subject to the provisions of clause (v) of this Section 2.12(e), the registered Holder may grant
proxies and otherwise authorize any person, including Agent Members (as defined below) and persons that may hold interests through Agent Members, to take any action which a holder is entitled to take under this Indenture or the Securities.

  
 (iv) In the event of the occurrence of any of
the events specified in clause (i) of this Section 2.12(e), the Company will promptly notify the Trustee and make available to the Trustee a reasonable supply of Certificated Securities in definitive, fully registered form. 
  
 (v) Neither any members of, or participants in, the
Depositary (collectively, the “Agent Members”) nor any other persons on whose behalf Agent Members may act shall have any rights under this Indenture with respect to any Global Security registered in the name of the Depositary or
any nominee thereof, or under any such Global Security, and the Depositary or such nominee, as the case may be, may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner and holder of such Global
Security for all purposes whatsoever; provided that an owner of a beneficial interest in a Global Security may directly enforce against the Company, without any proxy, comment, solicitation, waiver or any participation of the Depositary, its
right to exchange such beneficial interest for a Security in registered form pursuant to Section 2.12(e)(i) above. Notwithstanding the foregoing, nothing herein shall (A) prevent the Company, the Trustee or any agent of the Company or the Trustee
from giving effect to any written certification, proxy or other authorization furnished by the Depositary or such nominee, as the case may be, or (B) impair, as between the Depositary, its Agent Members and any other person on whose behalf an Agent
Member may act, the operation of customary practices of such Persons governing the exercise of the rights of a holder of any Security. 
  
 Section 2.13. CUSIP Numbers. The Company may issue the Securities with one or more “CUSIP” numbers (if then generally in use), and, if
so, the Trustee shall use “CUSIP” numbers in notices of redemption as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the
Securities or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers.
The Company will promptly notify the Trustee of any change in the CUSIP numbers.

 ARTICLE 3 
 REDEMPTION
AND REPURCHASES 
  
 Section 3.01.
Company’s Right to Redeem; Notices to Trustee. Prior to July 20, 2009, the Securities will not be redeemable at the Company’s option. Beginning on July 20, 2009, the Company, at its option, may redeem the Securities for cash at any
time as a whole, or from time to time in part, at a redemption price (the “Redemption Price”) equal to 100% of the principal amount of the Securities redeemed plus accrued and unpaid Interest and accrued and unpaid Liquidated
Damages, if any, on the Securities redeemed to (but excluding) the Redemption Date; provided that if the Redemption Date falls after an Interest Record Date and on or prior to the related Interest Payment Date, the Redemption Price shall only
be 100% of the principal amount of Securities to be redeemed and the Company shall pay such accrued and unpaid Interest to the record holder of the Securities on such Interest Record Date. If the Company elects to redeem Securities, it shall notify
the Trustee in writing of the Redemption Date, the Conversion Rate, the principal amount of Securities to be redeemed and the Redemption Price. 
  
 The Company shall give the notice to the Trustee provided for in this Section 3.01 by a Company Order, at least 30 days but not more than 60 days before
the Redemption Date (unless a shorter notice shall be satisfactory to the Trustee). 
  
 Section 3.02. Selection of Securities to be Redeemed. If less than all of the Securities are to be redeemed, unless the procedures of the Depositary provide otherwise, the Trustee shall select the Securities to
be redeemed by lot, on a pro rata basis or by another method the Trustee considers fair and appropriate (so long as such method is not prohibited by the rules of any stock exchange on which the Securities are then listed). Subject to the previous
sentence, the Trustee shall make the selection within five Business Days after it receives the notice provided for in Section 3.01 from outstanding Securities not previously called for redemption. The Trustee may select for redemption portions of
the principal amount of Securities that have denominations larger than $1,000. 
  
 Securities and portions of Securities that the Trustee selects shall be in principal amounts of $1,000 or an integral multiple of $1,000. Provisions of this Indenture that apply to Securities called for redemption
also apply to portions of Securities called for redemption. The Trustee shall notify the Company promptly of the Securities or portions of the Securities to be redeemed. 
  

 24 

 If any Security selected for partial redemption is converted in part pursuant to Section 10.01(a)(iii)
before termination of the conversion right with respect to the portion of the Security so selected, the converted portion of such Security shall be deemed (so far as may be) to be the portion selected for redemption. Securities that have been
converted during a selection of Securities to be redeemed may be treated by the Trustee as outstanding for the purpose of such selection. 
  
 Section 3.03. Notice of Redemption. At least 30 days but not more than 60 days before a Redemption Date, the Company shall mail a notice of
redemption by first-class mail, postage prepaid, to each Holder of Securities to be redeemed. 
  
 The notice shall identify the Securities to be redeemed and shall state: 
  
 (a) the Redemption Date; 
  
 (b) the Redemption Price; 
  
 (c) the Conversion Rate; 
  
 (d) the name and address of the Paying Agent and the Conversion Agent; 
  
 (e) that Securities called for redemption may be converted at any time before the close of business on the Business Day
prior to the Redemption Date; 
  
 (f) that Securities called for
redemption and not converted will be redeemed on the Redemption Date; 
  
 (g) that Holders who want to convert their Securities must satisfy the requirements set forth in the Securities; 
  
 (h) that Securities called for redemption must be surrendered to the Paying Agent to collect the Redemption Price; 
  
 (i) if fewer than all of the outstanding Securities are to be redeemed, the
certificate numbers, if any, and principal amounts of the particular Securities to be redeemed; 
  
 (j) that, unless the Company defaults in making payment of such Redemption Price, Interest and Liquidated Damages, if any, on Securities called for
redemption will cease to accrue on and after the Redemption Date; and 
  
 (k) the CUSIP number(s) of the Securities. 
  

 25 

 At the Company’s request, the Trustee shall give the notice of redemption in the Company’s name
and at the Company’s expense, provided that the Company makes such request at least seven Business Days prior to the date by which such notice of redemption must be given to Holders in accordance with this Section 3.03 and the text of
such notice is completed by the Company. 
  
 Section 3.04.
Effect of Notice of Redemption. Once notice of redemption is given, Securities called for redemption become due and payable on the Redemption Date and at the Redemption Price stated in the notice (except for Securities which are converted in
accordance with the terms of this Indenture) and from and after such date (unless the Company shall default in the payment of the Redemption Price) any accrued and unpaid Interest and Liquidated Damages, if any, on such Securities shall cease to
bear Interest. Upon surrender to the Paying Agent, such Securities shall be paid at the Redemption Price. 
  
 Section 3.05. Deposit of Redemption Price. Prior to 10:00 a.m. (New York City time), on the Redemption Date, the Company shall deposit with the
Paying Agent (or if the Company or a Subsidiary or an Affiliate of either of them is the Paying Agent, shall segregate and hold in trust) money sufficient to pay the Redemption Price of all Securities to be redeemed on that date other than
Securities or portions of Securities called for redemption which on or prior thereto have been delivered by the Company to the Trustee for cancellation or have been converted. The Paying Agent shall as promptly as practicable return to the Company
any money not required for that purpose because of conversion of Securities pursuant to Article 10. If such money is then held by the Company in trust and is not required for such purpose it shall be discharged from such trust. 
  
 Section 3.06. Securities Redeemed in Part. Upon surrender of a
Security that is redeemed in part, the Company shall execute and the Trustee shall authenticate and deliver to the Holder a new Security in an authorized denomination equal in principal amount to the unredeemed portion of the Security surrendered.

  
 Section 3.07. Repurchase of Securities by the Company at
Option of the Holder. Securities shall be purchased by the Company at the option of the Holder on July 15, 2009, July 15, 2014 and July 15, 2019 (each, a “Repurchase Date”), at a purchase price in cash equal to 100% of the
principal amount of those Securities, plus any accrued and unpaid Interest and accrued and unpaid Liquidated Damages, if any, on those Securities, to (but excluding) such Repurchase Date (the “Repurchase Price”); provided
that if any such Repurchase Date falls after an Interest Record Payment Date and on or prior to the related Interest Payment Date, the Repurchase Price shall only be 100% of the principal amount of those Securities and the Company shall pay such
accrued and unpaid Interest to the record holder of the Securities on such Interest Record Date. Not later than 25 Business Days prior to any Repurchase Date, the Company shall mail a Company Notice by first class mail to the Trustee and to each
Holder (and 
  

 26 

 to beneficial owners as required by applicable law). The Company Notice shall include a form of Repurchase Notice to be
completed by a Holder and shall state: 
  
 (a)
the Repurchase Price and the Conversion Rate; 
  
 (b) the name and address of the Paying Agent and the Conversion Agent; 
  
 (c) that Securities as to which a Repurchase Notice has been given may be converted if they are otherwise convertible only in accordance
with Article 10 hereof and the terms of the Securities if the applicable Repurchase Notice has been withdrawn in accordance with the terms of this Indenture; 
  

(d) that Securities must be surrendered to the Paying Agent to collect payment; 
  
 (e) that the Repurchase Price for any Security as to which a
Repurchase Notice has been given and not withdrawn will be paid promptly following the later of the Business Day immediately following the Repurchase Date and the time of surrender of such Security as described in (d); 
  
 (f) the procedures the Holder must follow to exercise its
put rights under this Section 3.07 and a brief description of those rights; 
  
 (g) briefly, the conversion rights, if any, with respect to the Securities; 
  
 (h) the procedures for withdrawing a Repurchase Notice; 
  
 (i) that, unless the Company defaults in making payment on Securities for which a Repurchase Notice has been
submitted, Interest or Liquidated Damages, if any, on such Securities will cease to accrue on and immediately after the Repurchase Date; and 
  
 (j) the CUSIP number of the Securities. 
  
 At the Company’s request, the Trustee shall give such Company Notice in the Company’s name and at the Company’s expense; provided,
however, that, in all cases, the text of such Company Notice shall be prepared by the Company. 
  
 Purchases of Securities hereunder shall be made, at the option of the Holder thereof, upon: 
  
 (i) delivery to the Paying Agent by the Holder of a written notice of repurchase (a “Repurchase
Notice”) during the period beginning at any time from the opening of business on the date that is 20 Business Days prior to the relevant Repurchase Date until the close of business on the Repurchase Date stating: 
  
 (A) the certificate number of the Security which the Holder
will deliver to be purchased or the appropriate Depositary procedures if Certificated Securities have not been issued for such Security, 
  

 27 

 (B) the portion of the principal amount of the Security which the Holder will deliver to
be purchased, which portion must be in principal amounts of $1,000 or an integral multiple of $1,000, and 
  
 (C) that such Security shall be purchased by the Company as of the Repurchase Date pursuant to the terms and conditions specified in
Section 5 of the Securities and in this Indenture; and 
  
 (ii) delivery of such Security to the Paying Agent at any time after delivery of the Repurchase Notice (together with all necessary endorsements) at the offices of the Paying Agent, such delivery being a condition to receipt by the Holder
of the Repurchase Price therefor; provided, however, that such Repurchase Price shall be so paid pursuant to this Section 3.07 only if the Security so delivered to the Paying Agent shall conform in all respects to the description thereof in
the related Repurchase Notice. 
  
 The Company shall purchase from
the Holder thereof, pursuant to this Section 3.07, a portion of a Security, if the principal amount of such portion is $1,000 or an integral multiple of $1,000. Provisions of this Indenture that apply to the purchase of all of a Security also apply
to the purchase of such portion of such Security. 
  
 Any purchase
by the Company contemplated pursuant to the provisions of this Section 3.07 shall be consummated by the delivery of the consideration to be received by the Holder promptly following the later of the Business Day immediately following the Repurchase
Date and the time of delivery of the Security.

 Section 3.08. Repurchase of Securities at Option of the Holder upon a Change of Control .

  
 (a) If a Change of Control occurs (subject to certain
exceptions set forth below), Securities not previously purchased or redeemed by the Company shall be purchased by the Company, at the option of the Holder thereof, at a purchase price equal to 100% of the principal amount of those Securities, plus
any accrued and unpaid Interest and accrued and unpaid Liquidated Damages, if any, on those Securities (the “Change of Control Repurchase Price”) to, but not including, the date that is 30 days following the date of the notice of a
Change of Control delivered by the Company pursuant to Section 3.08(b) (the “Change of Control Repurchase Date”), subject to satisfaction by or on behalf of the Holder of the requirements set forth in Section 3.08(c). If the Change
of Control Repurchase Date falls after an Interest Record Date and on or prior to the related Interest Payment Date, the Change of Control Repurchase Price shall be only 100% of the principal amount of those Securities and the Company shall pay such
accrued and unpaid Interest to the record holder of the Securities on such Interest Payment Date. 
  
 A “Change of Control” will be deemed to have occurred at such time after the original issuance of the Securities when any of the
following has occurred: 
  
 (i) the acquisition
by any Person, including any syndicate or group deemed to be a “person” under Section 13(d)(3) of the Exchange Act of beneficial ownership, directly or indirectly, through a purchase, merger or other acquisition transaction or
series of purchase, merger or other acquisition transactions, of shares of the Capital Stock of the Company entitling that Person to exercise 50% or more of the total voting power of all shares of the Capital Stock of the Company entitled to vote
generally in elections of directors, other than any acquisition by the Company, any Subsidiary of the Company, or any of the employee benefit plans of the Company (except that any of those Persons shall be deemed to have beneficial ownership of all
securities it has the right to acquire, whether the right is currently exercisable or is exercisable only upon the occurrence of a subsequent condition); 
  
 (ii) during any period of two consecutive years, individuals who at the beginning of such period constituted the board of directors
(together with any new directors whose election by the board of directors or whose nomination for election by stockholders of the Company was approved by a vote of a majority of the board of directors then still in office who were either directors
at the beginning of such period or whose election or nomination for election was previously so approved) cease for any reason to constitute a majority of the board of directors then in office; or 
  

 29 

 (iii) the Company consolidates or merges with or into any other Person (other than one or
more Subsidiaries of the Company), any merger of another Person (other than one or more Subsidiaries of the Company) into the Company, or any conveyance, transfer, sale, lease or other disposition of all or substantially all of the properties and
assets of the Company to another Person (other than one or more Subsidiaries of the Company), other than: (A) any transaction pursuant to which holders of shares of the Capital Stock of the Company immediately prior to the transaction have the
entitlement to exercise, directly or indirectly, 50% or more of the total voting power of all shares of Capital Stock of the Company entitled to vote generally in elections of directors of the continuing or surviving Person immediately after giving
effect to such issuance, or (B) any merger, share exchange, transfer of assets or similar transaction solely for the purpose of changing the jurisdiction of incorporation or form of organization of the Company and resulting in a reclassification,
conversion or exchange of outstanding shares of Common Stock, if at all, solely into shares of common stock, ordinary shares or American Depositary Shares or other equity interests of the surviving Person or a direct or indirect parent of the
surviving Person. 
  
 For the purposes of this Section 3.08(a),
(x) whether a person is a “beneficial owner” shall be determined in accordance with Rule 13d-3 under the Exchange Act and (y) the term “person” includes any syndicate or group that would be deemed to be a
“person” under Section 13(d)(3) of the Exchange Act. 
  
 Notwithstanding the foregoing, the Company shall not be required to purchase Securities of Holders upon a Change of Control pursuant to this Section 3.08(a) if 90% or more of the consideration received by stockholders of the Company in the
transaction or transactions (other than cash payments for fractional shares and cash payments made in respect of dissenters’ appraisal rights) constituting a Change of Control consists of shares of common stock traded or to be traded
immediately following a Change of Control on a national securities exchange or the Nasdaq National Market or that will be so traded or quoted when issued or exchanged in connection with a Change in Control, and, as a result of the transaction or
transactions, the Securities become convertible into that common stock (and any rights attached thereto). 
  
 (b) No later than 30 days after the occurrence of a Change of Control that is not subject to the exception set forth in Section 3.08(a), the Company shall
mail a Company Notice of the Change of Control by first class mail to the Trustee and to each Holder (and to beneficial owners as required by applicable law). The Company Notice shall include a form of Change of Control Repurchase Notice to be
completed by the Holder and shall state: 
  
 (i)
briefly, the events causing the Change of Control and the date of such Change of Control; 
  

 30 

 (ii) the date by which the Change of Control Repurchase Notice pursuant to this Section
3.08 must be delivered to the Paying Agent in order for a Holder to exercise the repurchase rights; 
  
 (iii) the Change of Control Repurchase Date; 
  
 (iv) the Change of Control Repurchase Price; 
  
 (v) the name and address of the Paying Agent and the Conversion Agent; 
  
 (vi) the Conversion Rate; 
  
 (vii) that the Securities as to which a Change of Control Repurchase Notice has been given may be converted
if they are otherwise convertible pursuant to Article 10 hereof only if the Change of Control Repurchase Notice has been withdrawn in accordance with the terms of this Indenture; 
  
 (viii) that the Securities must be surrendered to the Paying Agent to collect payment; 
  
 (ix) that the Change of Control Repurchase Price for any
Security as to which a Change of Control Repurchase Notice has been duly given and not withdrawn will be paid promptly following the later of the Business Day immediately following the Change of Control Repurchase Date and the time of surrender of
such Security as described in clause (viii); 
  
 (x) briefly, the procedures the Holder must follow to exercise rights under this Section 3.08; 
  
 (xi) briefly, the conversion rights, if any, on the Securities; 
  
 (xii) the procedures for withdrawing a Change of Control Repurchase Notice; 
  
 (xiii) that, unless the Company defaults in making payment
of such Change of Control Repurchase Price, Interest and Liquidated Damages, if any, on Securities surrendered for purchase by the Company will cease to accrue on and immediately after the Change of Control Repurchase Date; and 
  
 (xiv) the CUSIP number(s) of the Securities. 
  
 At the Company’s request, the Trustee shall give such Company Notice in
the Company’s name and at the Company’s expense; provided, however, that, in all cases, the text of such Company Notice shall be prepared by the Company. 
  

 31 

 (c) A Holder may exercise its rights specified in this Section 3.08 upon delivery of a written notice of
purchase (a “Change of Control Repurchase Notice”) to the Paying Agent at any time on or prior to the close of business on the Business Day immediately preceding the Change of Control Repurchase Date stating: 
  
 (i) the certificate number of the Security which the Holder
will deliver to be purchased or the appropriate Depositary procedures if Certificated Securities have not been issued; 
  
 (ii) the portion of the principal amount of the Security which the Holder will deliver to be purchased, which portion must be $1,000 or an
integral multiple of $1,000; and 
  
 (iii) that
such Security shall be purchased pursuant to the terms and conditions specified in the Securities and in this Indenture. 
  
 The delivery of such Security to the Paying Agent with the Change of Control Repurchase Notice (together with all necessary endorsements) at the offices
of the Paying Agent shall be a condition to the receipt by the Holder of the Change of Control Repurchase Price therefor; provided, however, that such Change of Control Repurchase Price shall be so paid pursuant to this Section 3.08 only if
the Security so delivered to the Paying Agent shall conform in all respects to the description thereof set forth in the related Change of Control Repurchase Notice. 
  
 The Company shall purchase from the Holder thereof, pursuant to this Section 3.08, a portion of a Security if the principal
amount of such portion is $1,000 or an integral multiple of $1,000. Provisions of this Indenture that apply to the purchase of all of a Security also apply to the purchase of such portion of such Security. 
  
 Any purchase by the Company contemplated pursuant to the provisions of this
Section 3.08 shall be consummated by the delivery of the Change of Control Repurchase Price to be received by the Holder on the Business Day immediately following the Change of Control Repurchase Date. 
  
 Notwithstanding anything herein to the contrary, any Holder delivering to the
Paying Agent the Change of Control Repurchase Notice contemplated by this Section 3.08(c) shall have the right to withdraw such Change of Control Repurchase Notice at any time prior to the close of business on the Business Day immediately preceding
the Change of Control Repurchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 3.09. 
  
 The Paying Agent shall promptly notify the Company of the receipt by it of any Change of Control Repurchase Notice or written withdrawal thereof.

  

 32 

 The Company will not be required to make a Change of Control offer upon a Change of Control if a third
party makes the Change of Control offer in the manner, at the times and otherwise in compliance with the requirements set forth herein applicable to a Change of Control offer made by the Company and purchases all Securities validly tendered and not
withdrawn under such Change of Control offer. 
  
 Section 3.09.
Effect of Repurchase Notice or Change of Control Repurchase Notice. 
  
 (a) Payment of the Repurchase Price or the Change of Control Repurchase Price for a Security for which a Repurchase Notice or a Change of Control Repurchase Notice, as the case may be, has been delivered and not
withdrawn in accordance with Section 3.09(b) or Section 3.09(c), as the case may be, is conditioned upon book-entry transfer or delivery of the Security, together with necessary endorsements, to the Paying Agent, or any other office of the Paying
Agent, at any time after delivery of the Repurchase Notice or the Change of Control Repurchase Notice, as the case may be. The Company shall pay the Repurchase Price or the Change of Control Repurchase Price to the Paying Agent promptly following
the later of the Repurchase Date or the Change of Control Repurchase Date or the time of book-entry transfer or delivery of the purchased Securities. If the Paying Agent holds money or securities sufficient to pay the Repurchase Price or the Change
of Control Repurchase Price on the Business Day immediately following the Repurchase Date or the Change of Control Repurchase Date, then: 
  
 (i) the purchased Securities will cease to be outstanding and interest and Liquidated Damages, if any, will cease to accrue, and

  
 (ii) all other rights of the Holders of such
purchased Securities will terminate (other than the right to receive the Repurchase Price or the Change of Control Repurchase Price upon delivery or transfer of such purchased Securities), 
  
 in each case, whether or not book-entry transfer of the purchased Securities is made or
whether or not the purchased Securities are delivered to the Paying Agent. 
  
 Securities in respect of which a Repurchase Notice or Change of Control Repurchase Notice has been given by the Holder thereof may not be converted pursuant to Article 10 hereof on or after the date of the delivery of
such Repurchase Notice or Change of Control Repurchase Notice unless such Repurchase Notice or Change of Control Repurchase Notice has first been validly withdrawn in accordance with Section 3.09(b) or Section 3.09(c). 
  
 (b) A Repurchase Notice or Change of Control Repurchase Notice may be
withdrawn by means of a written notice of withdrawal delivered to the office of the Paying Agent in accordance with the Repurchase Notice or Change of 
  

 33

to the Business Day immediately preceding the Change of Control Repurchase Date, as the case may be, specifying: 
  
 (i) the certificate number of the Security in respect of which such notice of withdrawal is being submitted or the appropriate Depositary
procedures if Certificated Securities have not been issued for such Security, 
  
 (ii) the principal amount of the Security with respect to which such notice of withdrawal is being submitted, and 
  
 (iii) the principal amount, if any, of such Security which remains subject to the original Repurchase Notice or Change of Control
Repurchase Notice, as the case may be, and which has been or will be delivered for purchase by the Company. 
  
 (c) There shall be no purchase of any Securities pursuant to Section 3.07 or 3.08 if there has occurred (prior to, on or after, as the case may be, the
giving, by the Holders of such Securities, of the required Repurchase Notice or Change of Control Repurchase Notice, as the case may be) and is continuing an Event of Default (other than a default that is cured by the payment of the Repurchase Price
or Change of Control Repurchase Price, as the case may be, with respect to such Securities). The Paying Agent will promptly return to the respective Holders thereof any Securities (x) with respect to which a Repurchase Notice or Change of Control
Repurchase Notice, as the case may be, has been withdrawn in compliance with this Indenture, or (y) held by it during the continuance of an Event of Default (other than a default that is cured by the payment of the Repurchase Price or Change of
Control Repurchase Price, as the case may be, with respect to such Securities) in which case, upon such return, the Repurchase Notice or Change of Control Repurchase Notice with respect thereto shall be deemed to have been withdrawn.

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

which is to be purchased only in part shall be surrendered at the office of the 
  

 34 

 Paying Agent (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 such Holder’s attorney duly authorized in writing) and the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such
Security, without service charge, a new Security or Securities, of any authorized denomination as requested by such Holder in aggregate principal amount equal to, and in exchange for, the portion of the principal amount of the Security so
surrendered which is not purchased.

obligations under Sections 3.07 and 3.08 to be exercised in the time and in the manner specified in Sections 3.07 and 3.08. 
  
 Section 3.13. Repayment to the Company. The Trustee and the Paying Agent shall return to the Company any cash that remains unclaimed as provided in
Section 12 of the Securities, together with interest, if any, thereon (subject to the provisions of Section 7.01(f)), held by them for the payment of the Repurchase Price or Change of Control Repurchase Price, as the case may be; provided,
however, that to the extent that the aggregate amount of cash deposited by the Company pursuant to Section 3.10 exceeds the aggregate Repurchase Price or Change of Control Repurchase Price, as the case may be, of the Securities or portions
thereof which the Company is obligated to purchase as of the Repurchase Date or Change of Control Repurchase Date, as the case may be, then, unless otherwise agreed in writing with the Company, promptly after the Business Day following the
Repurchase Date or Change of Control Repurchase Date, as the case may be, the Trustee shall return any such excess to the Company together with interest thereon (subject to the provisions of Section 7.01(f)). 
  
 ARTICLE 4 
 COVENANTS 
  
 Section 4.01. Payment of Securities. The Company shall promptly make all payments in respect of the Securities on the dates and in the manner provided in the Securities or pursuant to this Indenture. Any
amounts of cash in immediately available funds or shares of Common Stock to be given to the Trustee or Paying Agent, shall be deposited with the Trustee or Paying Agent by 10:00 a.m., New York City time, by the Company. The principal amount of, and
Interest and Liquidated Damages, if any, on the Securities, and the Redemption Price, Repurchase Price and the Change of Control Repurchase Price shall be 
  

 35 

 considered paid on the applicable date due if on such date (or, in the case of a Repurchase Price or a Change of Control
Repurchase Price, on the Business Day immediately following the applicable Purchase Date or Change of Control Repurchase Date, as the case may be) the Trustee or the Paying Agent holds, in accordance with this Indenture, cash or securities, if
permitted hereunder, sufficient to pay all such amounts then due. 
  
 Section 4.02. SEC and Other Reports. The Company shall file with the Trustee, within 15 days after it files such annual and quarterly reports, information, documents and other reports with the SEC, copies of its annual report and of
the information, documents and other reports (or copies of such portions of any of the foregoing as the SEC may by rules and regulations prescribe) which the Company is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange
Act; provided that any such reports, information or documents filed with the SEC pursuant to its Electronic Data and Gathering Analysis and Retrieval System shall be deemed to be filed with the Trustee. The Company shall comply with the other
provisions of TIA Section 314(a). Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained
therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely conclusively on Officers’ Certificates). 
  
 Section 4.03. Compliance Certificate. The Company shall deliver to the
Trustee within 120 days after the end of each fiscal year of the Company (beginning with the fiscal year ending December 31, 2004) an Officers’ Certificate, stating whether or not to the knowledge of the signers thereof, the Company is in
default in the performance and observance of any of the terms, provisions and conditions of this Indenture (without regard to any period of grace or requirement of notice provided hereunder) and if the Company shall be in default, specifying all
such defaults and the nature and status thereof of which they may have knowledge. 
  
 Section 4.04. Further Instruments and Acts. The Company will execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the
purposes of this Indenture. 
  
 Section 4.05. Maintenance of
Office or Agency. The Company will maintain in Chicago, an office or agency of the Trustee, Registrar, Paying Agent and Conversion Agent where Securities may be presented or surrendered for payment, where Securities may be surrendered for
registration of transfer, exchange, purchase, redemption or conversion and where notices and demands to or upon the Company in respect of the Securities and this Indenture may be served. The office of LaSalle Bank N.A. located at 135 S. LaSalle
Street, Suite 1960, Chicago, Illinois 60603, Attention: Erik R. Benson, shall initially be such 
  

 36 

 office or agency for all of the aforesaid purposes. The Company shall give prompt written notice to the Trustee of the
location, and of any change in the location, of any such office or agency (other than a change in the location of the office of the Trustee). If at any time the Company shall fail to maintain any such required office or agency or shall fail to
furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the address of the Trustee set forth in Section 12.02. 
  
 The Company may also from time to time designate one or more other offices or agencies where the Securities may be presented
or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or
agency in Chicago, for such purposes. 
  
 Section 4.06.
Delivery of Certain Information. At any time when the Company is not subject to Section 13 or 15(d) of the Exchange Act, upon the request of a Holder or any beneficial owner of Securities or holder or beneficial owner of shares of Common Stock
issued upon conversion thereof, the Company will promptly furnish or cause to be furnished Rule 144A Information (as defined below) to such Holder or any beneficial owner of Securities or holder or beneficial owner of shares of Common Stock, or to a
prospective purchaser of any such security designated by any such holder, as the case may be, to the extent required to permit compliance by such Holder or holder with Rule 144A under the Securities Act in connection with the resale of any such
security. “Rule 144A Information” shall be such information as is specified pursuant to Rule 144A(d)(4) under the Securities Act. Whether a person is a beneficial owner shall be determined by the Company to the Company’s
reasonable satisfaction. 
  
 Section 4.07. Liquidated
Damages Notice. In the event that the Company is required to pay Liquidated Damages to holders of Securities pursuant to the Registration Rights Agreement, the Company will provide written notice (the “Liquidated Damages
Notice”) to the Trustee of its obligation to pay Liquidated Damages prior to the Interest Record Date for the payment of Liquidated Damages, and the Liquidated Damages Notice shall set forth the amount of Liquidated Damages to be paid by
the Company on such payment date. The Trustee shall not at any time be under any duty to any holder of Securities to determine the Liquidated Damages, or with respect to the nature, extent or calculation of the amount of Liquidated Damages when
made, or with respect to the method employed in such calculation of the Liquidated Damages.

Indenture with the same effect as if such successor had been named as the Company herein; and thereafter, except in the case of a lease and obligations the Company may have under a supplemental indenture, the Company shall be discharged from all
obligations and covenants under this Indenture and the Securities. Subject to Section 9.06, the Company, the Trustee and the successor Person shall enter into a supplemental indenture to evidence the succession and substitution of such successor
Person and such discharge and release of the Company. 
  
 ARTICLE 6

 DEFAULTS AND REMEDIES 
  
 Section 6.01. Events and Defaults. 
  
 So long as any Securities are outstanding, each of the following shall be an “Event of Default”:

the right to convert a Security in accordance with Article 10 hereof, the Company (x) fails to 
  

 38 

 deliver the cash, shares of Common Stock, or the required combination of cash and shares of Common Stock
required to be delivered as part of the applicable Conversion Settlement Distribution on the applicable Conversion Settlement Date;

Holder’s right to require the Company to purchase such Securities pursuant to and in accordance with Section 3.07 or 3.08 hereof; 
  
 (c) the Company defaults in its obligation to redeem any Security, or any portion thereof, called for redemption by the Company pursuant
to and in accordance with Section 3.01 hereof; 
  
 (d) the Company fails to provide a Change of Control Repurchase Notice when due; 
  
 (e) the Company defaults in the payment of the principal amount of any Security when the same becomes due and payable at its Stated
Maturity; 
  
 (f) the Company defaults in the
payment of any Interest or Liquidated Damages, if any, when due and payable, and continuance of such default for a period of 30 days past the applicable due date; 
  
 (g) the Company fails to comply with any of the terms, agreements or covenants of the Company in the
Securities or this Indenture (other than those referred to in clause (a) through clause (f) above) and such failure continues for 60 days after receipt by the Company of a Notice of Default; 
  
 (h) a failure to pay when due at maturity or a default,
event of default or other similar condition or event (however described) that results in the acceleration of maturity of any indebtedness of the Company or any Designated Subsidiary in an aggregate amount of $25 million or more, unless the
acceleration is rescinded, stayed or annulled within 30 days after written notice of default is given to the Company by the Trustee or Holders of not less than 25% in aggregate principal amount of the Securities then outstanding; 
  
 (i) the entry by a court having jurisdiction in the premise
of (A) a decree or order for relief in respect of the Company, any Designated Subsidiary or any group of two or more Subsidiaries that, taken as a whole, would constitute a Designated Subsidiary in an involuntary case or proceeding under any
applicable bankruptcy, insolvency, reorganization or other similar law or (B) a decree or order adjudging the Company or any Designated Subsidiary, a bankrupt or insolvent, or approving as properly 
  

 39 

 filed a petition seeking reorganization, arrangement, adjustment or composition of or in respect of the
Company or any Designated Subsidiary under any applicable law, or appointing a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official of the Company or of any substantial part of its property, or ordering the
winding up or liquidation of its affairs, and the continuance of any such decree or order for relief or any such other decree or order described in Clause (A) or (B) above unstayed and in effect for a period of 90 consecutive days; and 

 
 (j) the commencement by the Company, any Designated
Subsidiary or any group of two or more Subsidiaries that, taken as a whole, would constitute a Designated Subsidiary of a voluntary case or proceeding under any applicable bankruptcy, insolvency, reorganization or other similar law or of any other
case or proceeding to be adjudicated a bankrupt or insolvent, or the consent by the Company or any Designated Subsidiary to the entry of a decree or order for relief in respect of the Company or any Designated Subsidiary in an involuntary case or
proceeding under any applicable bankruptcy, insolvency, reorganization or other similar law or to the commencement of any bankruptcy or insolvency case or proceeding against the Company, or the filing by the Company or any Designated Subsidiary of a
petition or answer or consent seeking reorganization or relief under any applicable law, or the consent by the Company to the filing of such petition or to the appointment of or the taking possession by a custodian, receiver, liquidator, assignee,
trustee, sequestrator or other similar official of the Company or of any substantial part of its property, or the making by the Company or any Designated Subsidiary of an assignment for the benefit of creditors, or the admission by the Company or
any Designated Subsidiary in writing of its inability to pay its debts generally as they become due, or the taking of corporate action by the Company or any Designated Subsidiary expressly in furtherance of any such action. 
  
 For the avoidance of doubt, clause (g) above shall not constitute an Event of
Default until the Trustee notifies the Company, or the Holders of at least 25% in aggregate principal amount of the Securities at the time outstanding notify the Company and the Trustee, of such default and the Company does not cure such default
(and such default is not waived) within the time specified in clause (g) above after actual receipt of such notice. Any such notice must specify the default, demand that it be remedied and state that such notice is a “Notice of
Default.” 
  
 The Trustee shall, within 90 days of the
occurrence of an Event of Default known to it, give to the Holders of the Securities notice of all uncured Events of Defaults known to it and written notice of any event which, with the giving of notice or the lapse of time, or both, would become an
Event of Default, its status and what action the Company is taking or proposes to take with respect thereto; provided, however, that the Trustee shall be protected in withholding such notice if it, in good faith, determines that the
withholding of such notice is in the best interest of such Holders, except in the case of an Event of Default specified in clauses (a) through (e) of this Section 6.01. 
  

 40 

 Section 6.02. Acceleration. If an Event of Default (other than an Event of Default specified in
Section 6.01(i) or 6.01(j) with respect to the Company) occurs and is continuing (the default not having been cured or waived), the Trustee by notice to the Company, or the Holders of at least 25% in aggregate principal amount of the Securities at
the time outstanding by notice to the Company and the Trustee, may declare the principal amount of the Securities and any accrued and unpaid Interest and accrued and unpaid Liquidated Damages, if any, on all the Securities to be immediately due and
payable. Upon such a declaration, such accelerated amount shall be due and payable immediately. If an Event of Default specified in Section 6.01(i) or 6.01(j) with respect to the Company occurs and is continuing, the principal amount of the
Securities and any accrued and unpaid Interest and accrued and unpaid Liquidated Damages, if any, on all the Securities shall become and be immediately due and payable without any declaration or other act on the part of the Trustee or any
Securityholders. The Holders of a majority in aggregate principal amount of the Securities at the time outstanding, by notice to the Trustee (and without notice to any other Securityholder) may rescind an acceleration and its consequences if the
rescission would not conflict with any judgment or decree and if all existing Events of Default have been cured or waived except nonpayment of the principal amount of the Securities and any accrued and unpaid Interest and accrued and unpaid
Liquidated Damages, if any, that have become due solely as a result of acceleration. No such rescission shall affect any subsequent Event of Default or impair any right consequent thereto. 
  
 Section 6.03. Other Remedies. If an Event of Default occurs and is
continuing, the Trustee may pursue any available remedy to collect the payment of the principal amount of the Securities and any accrued and unpaid Interest and accrued and unpaid Liquidated Damages, if any, on the Securities or to enforce the
performance of any provision of the Securities or this Indenture. 
  
 The Trustee may maintain a proceeding even if the Trustee does not possess any of the Securities or does not produce any of the Securities in the proceeding. A delay or omission by the Trustee or any Securityholder in exercising any right
or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of, or acquiescence in, the Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative. 
  
 Section 6.04. Waiver of Past Defaults. The Holders of a majority in
aggregate principal amount of the Securities at the time outstanding, by notice to the Trustee (and without notice to any other Securityholder), may waive an existing or past Event of Default and its consequences except (a) an Event of Default
described in Section 6.01 clauses (a) through (f) or (b) an Event of Default in respect of a provision that under Section 9.02 cannot be amended 
  

 41 

 without the consent of each Securityholder affected. When an Event of Default is waived, it is deemed cured, but no such
waiver shall extend to any subsequent or other Event of Default or impair any consequent right. This Section 6.04 shall be in lieu of Section 316(a)1(B) of the TIA and such Section 316(a)1(B) is hereby expressly excluded from this Indenture, as
permitted by the TIA. 
  
 Section 6.05. Control by Majority.
The Holders of a majority in aggregate principal amount of the Securities at the time outstanding may direct, through the written consent of such Holders, the time, method and place of conducting any proceeding for any remedy available to the
Trustee or of exercising any trust or power conferred on the Trustee. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture or that the Trustee determines in good faith is unduly prejudicial to the rights
of other Securityholders or would involve the Trustee in personal liability unless the Trustee is offered indemnity satisfactory to it. This Section 6.05 shall be in lieu of Section 316(a)1(A) of the TIA and such Section 316(a)1(A) is hereby
expressly excluded from this Indenture, as permitted by the TIA. 
  
 Section 6.06. Limitation on Suits. A Securityholder may not pursue any remedy with respect to this Indenture or the Securities, except in the case of an Event of Default specified in Section 6.01(e) and Section 6.01(f), unless:

  
 (a) the Holder gives to the Trustee written
notice stating that an Event of Default is continuing; 
  
 (b) the Holders of at least 25% in aggregate principal amount of the Securities at the time outstanding make a written request to the Trustee to pursue the remedy; 
  
 (c) such Holder or Holders offer to the Trustee security or indemnity satisfactory to the Trustee against
any loss, liability or expense; 
  
 (d) the
Trustee does not comply with the request within 60 days after receipt of such request and offer of security or indemnity; and 
  
 (e) the Holders of a majority in aggregate principal amount of the Securities at the time outstanding do not give the Trustee a direction
inconsistent with the request during such 60-day period. 
  
 A
Securityholder may not use this Indenture to prejudice the rights of any other Securityholder or to obtain a preference or priority over any other 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 the principal amount of the Securities and any accrued and unpaid Interest and accrued and unpaid Liquidated Damages, if any, in respect of the Securities held 
  

 42 

 by such Holder, on or after the respective due dates expressed in the Securities or any Redemption Date, Repurchase Date
or Change of Control Repurchase Date, and to convert the Securities in accordance with Article 10, or to bring suit for the enforcement of any such payment on or after such respective dates or the right to convert, shall not be impaired or affected
adversely without the consent of such Holder. 
  
 Section 6.08.
Collection Suit by Trustee. If an Event of Default described in Section 6.01 clauses (a) through (f) 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 owing with respect to the Securities and the amounts provided for in Section 7.07. 
  
 Section 6.09. Trustee May File Proofs of Claim. In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial
proceeding relative to the Company or any other obligor upon the Securities or the property of the Company or of such other obligor or their creditors, the Trustee (irrespective of whether the principal amount of the Securities and any accrued and
unpaid Interest and accrued and unpaid Liquidated Damages, if any, in respect of the Securities shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on
the Company for the payment of any such amount) shall be entitled and empowered, by intervention in such proceeding or otherwise: 
  
 (a) to file and prove a claim for the whole principal amount of the Securities and any accrued and unpaid Interest and accrued and unpaid Liquidated
Damages, if any, and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its
agents and counsel or any other amounts due the Trustee under Section 7.07) and of the Holders allowed in such judicial proceeding, and 
  
 (b) to 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 such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments
directly to the Holders, to pay 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. 
  
 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. 
  

 43 

 Section 6.10. Priorities. If the Trustee collects any money pursuant to this Article 6, 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 amounts due and unpaid on the Securities for the principal amount of the Securities and any accrued and unpaid Interest and accrued and unpaid Liquidated Damages, if any, as the case may be, ratably, without preference or
priority of any kind, according to such amounts due and payable on the Securities; and 
  
 THIRD: the balance, if any, to the Company. 
  
 The Trustee may fix a record date and payment date for any payment to Securityholders pursuant to this Section 6.10. At least 15 days before such record date, the Trustee shall mail to each Securityholder and the
Company a notice that states the record date, the payment date and the amount to be paid. 
  
 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 (other than the Trustee) in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees
and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee. This Section 6.11 shall be in lieu
of Section 315(e) of the TIA and such Section 315(e) is hereby expressly excluded from this Indenture, as permitted by the TIA. 
  
 Section 6.12. Waiver of Stay, Extension or Usury Laws. The Company covenants (to the extent that it may lawfully do so) that it will not at any
time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law or any usury or other law wherever enacted, now or at any time hereafter in force, which would prohibit or forgive the
Company from paying all or any portion of the principal amount of the Securities and any accrued and unpaid Interest and accrued and unpaid Liquidated Damages, if any, on Securities, as contemplated herein, or which may affect the covenants or the
performance of this Indenture; and the Company (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 hinder, delay or impede the execution of any power herein
granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

 ARTICLE 7 
 TRUSTEE 
  
 Section
7.01. Duties of Trustee. The duties and responsibilities of the Trustee shall be as provided by the TIA and as set forth herein. 
  
 (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise the rights and powers vested in it by this Indenture and use the
same degree of care and skill in its exercise as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs. 
  
 (b) Except during the continuance of an Event of Default: 
  
 (i) the Trustee need perform only those duties that are specifically set forth in this Indenture and no
others, and no implied duties shall be read into this Indenture against the Trustee; and 
  
 (ii) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of
the opinions expressed therein, upon 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. This Section 7.01(b) shall be in lieu of Section 315(a) of the TIA and such Section 315(a) is hereby expressly excluded from this Indenture, as permitted by the TIA. 
  
 (c) The Trustee may not be relieved from liability for its own negligent
action, its own negligent failure to act or its own willful misconduct, except that: 
  
 (i) this Section (c) does not limit the effect of Section 7.01(b); 
  
 (ii) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer
unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; and

 (g) No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance
of any of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it.

  
 Section 7.02. Rights of Trustee. Subject to its duties
and responsibilities under the TIA: 
  
 (a) the Trustee may
conclusively rely and shall be protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness

discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and
premises of the Company, personally or by agent or attorney at the sole cost of the Company and shall incur no liability or additional liability of any kind by reason of such inquiry or investigation; 
  
 (i) the Trustee shall not be deemed to have notice of any default or Event of
Default unless a Responsible Officer of the Trustee has actual knowledge thereof or unless written notice of any event which is in fact such a default is received by the Trustee at the Corporate Trust Office of the Trustee, and such notice
references the Securities and this Indenture; 
  
 (j) 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 to each agent,
custodian and other person employed to act hereunder; and 
  
 (k)
the Trustee may request that the Company deliver an Officers’ Certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture, which Officers’
Certificate may be signed by any person authorized to sign an Officers’ Certificate, including any person specified as so authorized in any such certificate previously delivered and not superseded. 
  
 Section 7.03. Individual Rights of Trustee. The Trustee in its
individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee. Any Paying Agent, Registrar, Conversion Agent or
co-registrar may do the same with like rights. However, the Trustee must comply with Sections 7.10 and 7.11. 
  

 47 

 Section 7.04. Trustee’s Disclaimer. The Trustee makes no representation as to the validity or
adequacy of this Indenture or the Securities, it shall not be accountable for the Company’s use or application of the proceeds from the Securities, it shall not be responsible for any statement in the registration statement for the Securities
under the Securities Act or in any offering document for the Securities, the Indenture or the Securities (other than its certificate of authentication), or the determination as to which beneficial owners are entitled to receive any notices
hereunder. 
  
 Section 7.05. Notice of Defaults. If a
default or Event of Default occurs and if it is known to the Trustee, the Trustee shall give to each Securityholder notice of the default or Event of Default within 90 days after it occurs or, if later, within 15 days after it is known to the
Trustee, unless such default or Event of Default shall have been cured or waived before the giving of such notice. Notwithstanding the preceding sentence, except in the case of a default or Event of Default described in Section 6.01 clauses (a)
through (f), the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interest of the Securityholders. The preceding sentence shall be in lieu of the
proviso to Section 315(b) of the TIA and such proviso is hereby expressly excluded from this Indenture, as permitted by the TIA. The Trustee shall not be deemed to have knowledge of a default or Event of Default unless a Responsible Officer of the
Trustee has received written notice of such default or Event of Default, which notice specifically references this Indenture and the Securities. 
  
 Section 7.06. Reports by Trustee to Holders. Within 75 days after each December 31 beginning with the December 31 following the date of this
Indenture, the Trustee shall mail to each Securityholder a brief report dated as of such December 31 that complies with TIA Section 313(a), if required by such Section 313(a). The Trustee also shall comply with TIA Section 313(b). 
  
 A copy of each report at the time of its mailing to Securityholders shall be
filed with the SEC and each securities exchange, if any, on which the Securities are listed. The Company agrees to notify the Trustee promptly whenever the Securities become listed on any securities exchange and of any delisting thereof. 

 
 Section 7.07. Compensation and Indemnity. The Company agrees:

  
 (a) to pay to the Trustee from time to time such compensation
as the Company and the Trustee shall from time to time agree in writing for all services rendered by it hereunder (which compensation shall not be limited (to the extent permitted by law) by any provision of law in regard to the compensation of a
trustee of an express trust); 
  
 (b) to reimburse the Trustee
upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any provision of this Indenture (including the reasonable compensation and the 
  

 48 

 expenses, advances and disbursements of its agents and counsel), except any such expense, disbursement or advance as
shall be determined to have been caused by its own negligence or willful misconduct; and 
  
 (c) to indemnify the Trustee or any predecessor Trustee and their agents for, and to hold them harmless against, any loss, damage, claim, liability, cost or expense (including reasonable attorney’s fees and
expenses, and taxes (other than taxes based upon, measured by or determined by the income of the Trustee)) incurred without negligence or willful misconduct on its part, arising out of or in connection with the acceptance or administration of this
trust, including the costs and expenses of defending itself against any claim (whether asserted by the Company or any Holder or any other person) or liability in connection with the exercise or performance of any of its powers or duties hereunder.

  
 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, except that held in trust to pay the principal amount of, or the Redemption Price, Repurchase Price, Change of Control
Repurchase Price, Interest or Liquidated Damages, if any, as the case may be, on particular Securities. 
  
 The Company’s payment obligations pursuant to this Section 7.07 shall survive the discharge of this Indenture and the resignation or removal of the
Trustee. When the Trustee incurs expenses after the occurrence of an Event of Default specified in Section 6.01(i) or 6.01(j), the expenses, including the reasonable charges and expenses of its counsel, are intended to constitute expenses of
administration under any bankruptcy law. 
  
 Section 7.08.
Replacement of Trustee. The Trustee may resign by so notifying the Company; provided, however, no such resignation shall be effective until a successor Trustee has accepted its appointment pursuant to this Section 7.08. The Holders of a
majority in aggregate principal amount of the Securities at the time outstanding may remove the Trustee by so notifying the Trustee and the Company. The Company shall remove the Trustee if: 
  
 (a) the Trustee fails to comply with Section 7.10; 
  
 (b) the Trustee is adjudged bankrupt or insolvent; 
  
 (c) a receiver or public officer takes charge of the Trustee or its
property; or 
  
 (d) the Trustee otherwise 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, by resolution of its Board of Directors, a successor Trustee. 
  

 49 

 A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to
the Company satisfactory in form and substance to the retiring Trustee and 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. 
  
 If a successor Trustee does not take
office within 30 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company or the Holders of a majority in aggregate principal amount of the Securities at the time outstanding may petition any court of competent
jurisdiction at the expense of the Company for the appointment of a successor Trustee. 
  
 If the Trustee fails to comply with Section 7.10, any Securityholder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 
  
 So long as no event which is, or after notice or lapse of time, or both,
would become, an Event of Default shall have occurred and be continuing, if the Company shall have delivered to the Trustee (i) a Board Resolution appointing a successor Trustee, effective as of a date specified therein, and (ii) an instrument of
acceptance of such appointment, effective as of such date, by such successor Trustee in accordance with this Indenture, the Trustee shall be deemed to have resigned as contemplated in this Section 7.08, the successor Trustee shall be deemed to have
been accepted as contemplated in this Indenture, all of such date, and all other provisions of this Indenture shall be applicable to such resignation, appointment and acceptance. 
  
 Section 7.09. Successor Trustee by Merger. If the Trustee consolidates with, merges or converts into, or transfers
all or substantially all its corporate trust business or assets to, another corporation, the resulting, surviving or transferee corporation without any further act shall be the successor Trustee. 
  
 Section 7.10. Eligibility; Disqualification. The Trustee shall at all
times satisfy the requirements of TIA Sections 310(a)(1) and 310(b). The Trustee (or its parent holding company) shall have a combined capital and surplus of at least $50,000,000 as set forth in its most recent published annual report of condition.
Nothing herein contained shall prevent the Trustee from filing with the SEC the application referred to in the penultimate paragraph of TIA Section 310(b). 
  
 Section 7.11. Preferential Collection of Claims Against Company. The Trustee shall comply with TIA Section 311(a), excluding any creditor
relationship listed in TIA Section 311(b). A Trustee who has resigned or been removed shall be subject to TIA Section 311(a) to the extent indicated therein. 
  

 50 

 ARTICLE 8 
 DISCHARGE OF INDENTURE 
  
 Section 8.01. Discharge of Liability on Securities. When (i) the Company delivers to the Trustee all outstanding Securities (other than Securities
replaced or repaid pursuant to Section 2.07) for cancellation or (ii) all outstanding Securities have become due and payable and the Company deposits with the Trustee cash sufficient to pay all amounts due and owing on all outstanding Securities
(other than Securities replaced pursuant to Section 2.07), and if in either case the Company pays all other sums payable hereunder by the Company, then this Indenture shall, subject to Section 7.07, cease to be of further effect. The Trustee shall

Trustee and the Paying Agent shall return to the Company upon written request any money or securities held by them for the payment of any amount with respect to the Securities that remains unclaimed for two years, subject to applicable unclaimed
property law. After return to the Company, Holders entitled to the money or securities must look to the Company for payment as general creditors unless an applicable abandoned property law designates another person and the Trustee and the Paying
Agent shall have no further liability to the Securityholders with respect to such money or securities for that period commencing after the return thereof. 
  
 ARTICLE 9

of the Debentures” in the Offering Memorandum relating to the Securities will not be deemed to adversely affect the interests of the Holders of the Securities. 
  
 Section 9.02. With Consent of Holders. Except as provided below in this Section 9.02, this Indenture (including the
terms and conditions of the Securities) or the Securities may be amended, modified or supplemented, and noncompliance 
  

 52 

 in any particular instance with any provision of this Indenture or the Securities may be waived, in each case with the
written consent of the Holders of at least a majority of the principal amount of the Securities at the time outstanding. 
  
 Without the written consent or the affirmative vote of each Holder of Securities affected thereby, an amendment, supplement or waiver under this Section
9.02 may not: 
  
 (a) change the maturity of any
Security, or the payment date of any installment of Interest or Liquidated Damages payable on any Security;

 53 

 (k) reduce the percentage of the aggregate principal amount of the outstanding Securities
the consent of whose Holders is required for any such supplemental indenture entered into in accordance with this Section 9.02 or the consent of whose Holders is required for any waiver provided for in this Indenture. 
  
 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, but it shall be sufficient if such consent approves the substance thereof. 
  
 After an amendment under this Section 9.02 becomes effective, the Company shall mail to each Holder a notice briefly describing the amendment. The failure
to give such notice to each Holder, or any defect therein, shall not impair or affect the validity of an amendment under this Section 9.02.

Holder and every subsequent Holder of that Security or portion of the Security that evidences the same obligation as the consenting Holder’s Security, even if notation of the consent, waiver or action is not made on the Security. However, any
such Holder or subsequent Holder may revoke the consent, waiver or action as to such Holder’s Security or portion of the Security if the Trustee receives the notice of revocation before the date the amendment, waiver or action becomes
effective. After an amendment, waiver or action becomes effective, it shall bind every Securityholder. 
  
 Section 9.05. Notation On or Exchange Of Securities. Securities authenticated and delivered after the execution of any supplemental indenture
pursuant to this Article may, and shall if required by the Trustee, bear a notation in form approved by the Trustee as to any matter provided for in such supplemental indenture. If the Company shall so determine, new Securities so modified as to

 54

indenture authorized pursuant to this Article 9 if the amendment contained therein does not affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may, but need not, sign such supplemental indenture. In signing

 ARTICLE 10 
 CONVERSIONS

  
 Section 10.01. Conversion Privilege. 
  
 (a) Subject to and upon compliance with the provisions of this Article 10
(including without limitation the Company’s right, in its sole and absolute discretion, to satisfy its Conversion Obligation in any manner permitted pursuant to Section 10.03), a Holder of a Security shall have the right, at such Holder’s
option, to convert all or any portion (if the portion to be converted is $1,000 principal amount or an integral multiple thereof) of such Security at any time prior to the close of business on the Stated Maturity at the Conversion Rate (the
“Conversion Obligation”) in effect on the date of conversion: 
  
 (i) during any fiscal quarter of the Company (a “Fiscal Quarter”) (and only during such Fiscal Quarter) commencing after
September 30, 2004, if the Last Reported Sale Price of the Common Stock for at least 20 consecutive Trading Days in the 30 consecutive Trading Day period ending on the last Trading Day of the immediately preceding Fiscal Quarter was more than 130%
of the Conversion Price in effect on such 30th Trading Day; 
  
 (ii) during the five consecutive Business Day period immediately after any five consecutive Trading Day period (the “Measurement Period”) in which the Trading Price per $1,000 principal amount of the
Securities for each day of such Measurement Period was less than 98% of the product of the Last Reported Sale Price on such date and the Conversion Rate on such date; provided, however, that Securities may not be converted in reliance on this
subsection after July 15, 2019 if on any Trading Day during the Measurement Period the Last Reported Sale Price was between 100% and 130% of the Conversion Price on such Trading Day. 
  

 55 

 (iii) at any time prior to the close of business on the Business Day prior to the
Redemption Date, if such Security has been called for redemption pursuant to Article 3 hereof; and 
  
 (iv) as provided in clause (b) of this Section 10.01. 
  
 The Company or a designated agent shall determine on a daily basis whether the Securities shall be convertible as a result
of the occurrence of an event specified in clause (a) above and, if the Securities shall be so convertible, the Company shall promptly deliver to the Trustee and the Conversion Agent written notice thereof. Whenever the Securities shall become
convertible pursuant to Section 10.01, the Company or, at the Company’s request, the Trustee in the name and at the expense of the Company, shall promptly notify the Holders of the event triggering such convertibility in the manner provided in
Section 12.02, and the Company shall also promptly publicly announce such information. Any notice so given shall be conclusively presumed to have been duly given, whether or not the Holder receives such notice. 
  
 (b) In addition, in the event that: 
  
 (i) the Company distributes to all Holders of Common Stock
rights entitling them to purchase, for a period expiring within 60 days after such distribution, Common Stock at less than the Last Reported Sale Price of the Common Stock on the Business Day immediately preceding the date of the announcement of
such distribution; or 
  
 (ii) the Company
distributes to all Holders of Common Stock cash or other assets, debt securities or rights to purchase the Company’s securities, which distribution has a per share value, as determined by the Board of Directors, exceeding 10% of the Last
Reported Sale Price of the Common Stock on the Business Day immediately preceding the date of the announcement of such distribution, 
  
 then, in each case, the Securities may be surrendered for conversion at any time on and after the date that the Company gives notice to the Holders of
such right, which shall be not less than 20 days prior to the Ex-Dividend Date for such distribution, until the earlier of the close of business on the Business Day immediately preceding the Ex-Dividend Date or the date the Company announces that
such distribution will not take place, or 
  
 (iii) a Change of Control occurs (A) pursuant to clause (i) of the definition thereof (if the Holders of Securities have the right to cause the Company to purchase those Securities pursuant to Section 3.08)or (B) pursuant to clause (iii) of
the definition thereof (regardless of whether the Holders of Securities have the right to cause the Company to purchase those Securities pursuant to Section 3.08), 
  

 56 

 then the Securities may be surrendered for conversion at any time from and after the date which is 15
days prior to the date announced by the Company as the anticipated effective time of such transaction until 15 days after the effective date of the transaction or, if such transaction also results in a Change of Control Repurchase Date, until the
Change of Control Repurchase Date, and, at such effective time, the right to convert the Securities into shares of Common Stock shall be changed, as set forth in Section 10.05, into a right to convert into the kind and amount of such cash,
securities or other property which the Holder of such Securities would have received if such Holder had converted the Securities immediately prior to such transaction. The Company shall notify Holders and the Trustee at the same time the Company
publicly announces such transaction (but in no event less than 15 days prior to the effective date of such transaction to the extent practicable). 
  
 Notwithstanding the foregoing, the Securities will not be convertible pursuant to clauses (i) or (ii) above and no adjustment to the Conversion Rate will be made if the
Company provides that Holders of Securities will participate in such distribution without conversion. 
  
 (c) If a Holder elects to convert Securities in connection with a Change of Control pursuant to clause (3) of the definition thereof that occurs prior to
June 15, 2009 and 10% or more of the consideration for the Common Stock (other than cash payments for fractional shares and cash payments made in respect of dissenters’ appraisal rights) in such Change of Control transaction consists of cash or
securities (or other property) that are not traded or scheduled to be traded immediately following such transaction on a U.S. national securities exchange or the Nasdaq National Market, such Holder will be entitled to receive, in addition to a
number of shares of Common Stock equal to the Conversion Rate per $1,000 principal amount of Securities, an additional number of shares of Common Stock (the “Additional Shares”) as described below, subject to the Company’s
payment elections as described in Section 10.03; provided that if the Stock Price is equal to or greater than $30.00 or less than $8.04 (subject in each case to adjustment as described below), the number of Additional Shares shall be zero.
The Additional Shares will not be payable in Shares of Common Stock, but will represent a right to receive the aggregate amount of cash, securities or other property into which the Additional Shares would convert into in the transaction from the
surviving entity (or an indirect or direct parent thereof). 
  
 The number of Additional Shares will be determined by reference to the table attached as Schedule A hereto, based on the effective date of such Change of Control transaction and the Stock Price; provided that if the Stock Price is
between two Stock Price amounts in the table or such effective date is between two Effective Dates in the table, the number of Additional Shares will be 
  

 57 

 determined by a straight-line interpolation between the number of Additional Shares set forth for the higher and lower
Stock Price amounts and the two effective dates, as applicable, based on a 365-day year. 
  
 The Stock Prices set forth in the first row of the table in Schedule A hereto will be adjusted as of any date on which the Conversion Rate of the Debentures is adjusted. The adjusted Stock Prices will equal the Stock
Prices applicable immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the Conversion Rate immediately prior to the adjustment giving rise to the Stock Price adjustment and the denominator of which is the
Conversion Rate as so adjusted. The number of Additional Shares will be adjusted in the same manner as the Conversion Rate as set forth Section 10.04. 
  
 Notwithstanding the foregoing, in no event will the total number of shares of Common Stock issuable upon conversion exceed 124.3781 per $1,000 principal
amount of Securities, subject to adjustments in the same manner as the Conversion Rate as set forth in Section 10.04. 
  
 Section 10.02. Conversion Procedure; Conversion Rate; Fractional Shares. 
  
 (a) Subject to Section 10.01 and the Company’s rights under Section 10.03, each Security shall be convertible at the
office of the Conversion Agent into fully paid and nonassessable shares (calculated to the nearest 1/100th of a share) of Common Stock. The rate at which shares of Common Stock shall be delivered upon conversion (the “Conversion
Rate”) shall be initially 88.8415 shares of Common Stock for each $1,000 principal amount of Securities. The Conversion Rate shall be adjusted in certain instances as provided in Section 10.04 hereof, but shall not be adjusted for any
accrued and unpaid Interest or Liquidated Damages, if any. Upon conversion, no payment shall be made by the Company with respect to any accrued and unpaid Interest. Instead, such amount shall be deemed paid by the applicable Conversion Settlement
Distribution delivered upon conversion of any Security into Common Stock. In addition, no payment or adjustment shall be made in respect of dividends on the Common Stock with a record date prior to the date of conversion. Notwithstanding the
foregoing, upon conversion a Holder shall receive any accrued and unpaid Liquidated Damages to the Conversion Date. The Company shall not issue any fraction of a share of Common Stock in connection with any conversion of Securities, but instead
shall, subject to Section 10.04 hereof, make a cash payment (calculated to the nearest cent) equal to such fraction multiplied by the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the Conversion Date.

  
 (b) Before any Holder of a Security shall be entitled to
convert the same into Common Stock, such Holder shall (1) in the case of Global Securities, comply with the procedures of the Depositary in effect at that time and furnish appropriate endorsement and transfer documents, and (2) in the case of

  

 58 

 Certificated Securities, surrender such Securities, duly endorsed to the Company or in blank (and accompanied by
appropriate endorsement and transfer documents), at the office of the Conversion Agent, and give written notice to the Conversion Agent in the form on the reverse of such Certificated Security (or a facsimile thereof) (a “Notice of
Conversion”) at said office or place that such Holder elects to convert the same and shall state in writing therein the principal amount of Securities to be converted and the name or names (with addresses) in which such Holder wishes the
certificate or certificates for Common Stock included in the Conversion Settlement Distribution, if any, to be registered. 
  
 Before any such conversion, a Holder also shall pay all taxes or duties, if any, as provided in Section 10.06 and any amount payable pursuant to Section
10.02(g). 
  
 If more than one Security shall be surrendered for
conversion at one time by the same Holder, the number of full shares of Common Stock, if any, that shall be deliverable upon conversion as part of the Conversion Settlement Distribution shall be computed on the basis of the aggregate principal
amount of the Securities (or specified portions thereof to the extent permitted thereby) so surrendered. 
  
 (c) A Security shall be deemed to have been converted immediately prior to the close of business on the date (the “Conversion Date”) that
is the latest of: (i) the date the Holder has complied with Section 10.02(b), (ii) the expiration of the Cash Settlement Notice Period or (iii) if the Company elects to pay cash in lieu of Common Stock pursuant to Section 10.03, the expiration of
the Conversion Retraction Period. 
  
 (d) Subject to the next
succeeding sentence, the Company will, on the Conversion Settlement Date, (i) pay the cash component (including cash in lieu of any fraction of a share to which such Holder would otherwise be entitled), if any, of the Conversion Settlement
Distribution determined pursuant to Section 10.03 to the Holder of a Security surrendered for conversion, or such Holder’s nominee or nominees, and (ii) issue, or cause to be issued, and deliver to the Conversion Agent or to such Holder, or
such Holder’s nominee or nominees, certificates or a book-entry transfer through the Depositary for the number of full shares of Common Stock, if any, to which such Holder shall be entitled as part of such Conversion Settlement Distribution.

  
 (e) In case any Security shall be surrendered for partial
conversion, the Company shall execute and the Trustee shall authenticate and deliver to or upon the written order of the Holder of the Security so surrendered, without charge to such Holder (subject to the provisions of Section 10.06 hereof), a new
Security or Securities in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Securities. 
  
 (f) By delivering the applicable Conversion Settlement Distribution upon conversion of any Security to the Conversion Agent or to the Holder or such

  

 59 

 Holder’s nominee or nominees, the Company will have satisfied in full its Conversion Obligation with respect to such
Security, and upon such delivery accrued and unpaid Interest with respect to such Security will be deemed to be paid in full rather than canceled, extinguished or forfeited. 
  
 (g) If a Securityholder delivers a Notice of Conversion after the Interest Record Date for a payment of Interest but prior
to the corresponding Interest Payment Date, such Securityholder must pay to the Company, at the time such Securityholder surrenders Securities for conversion, an amount equal to the Interest excluding, for the avoidance of doubt, Liquidated Damages,
if any, that has accrued and will be paid on the related Interest Payment Date. This Section 10.02(g) shall not apply to a Securityholder that converts Securities after an Interest Record Date for a payment of Interest but on or prior to the
corresponding Interest Payment Date if (1) the Company has specified a Redemption Date during such period, (2) the Company has specified a Change of Control Repurchase Date during such period or (3) to the extent of any overdue Interest if any
overdue Interest exists at the time of conversion with respect to the Securities converted. Notwithstanding the foregoing, the Company shall refund any amount paid by a Securityholder pursuant to this Section 10.02(g) if the Cash Settlement Notice
Period or, if the Company elects to pay cash in lieu of Common Stock pursuant to Section 10.03, the Cash Settlement Averaging Period, ends on or subsequent to the Interest Payment Date immediately following the date such Securityholder delivered a
Notice of Conversion. Such refunded amount shall be paid at the time of delivery of the Conversion Settlement Distribution following conversion of any Securities. 
  
 Section 10.03. Payment of Cash In Lieu of Common Stock. 
  
 (a) If a Holder elects to convert all or any portion of a Security into
shares of Common Stock as set forth in Section 10.01 and the Company receives such Holder’s Notice of Conversion on or prior to the day that is 20 calendar days prior to the Stated Maturity, or with respect to Securities called for redemption
pursuant to Section 3.01, the applicable Redemption Date (the “Final Notice Date”), the Company may choose to satisfy all or any portion of its Conversion Obligation in cash. Upon such election, the Company will notify such Holder
through the Trustee of the dollar amount to be satisfied in cash (which must be expressed either as 100% of the Conversion Obligation or as a fixed dollar amount) at any time on or before the date that is two Business Days following the
Company’s receipt of the Notice of Conversion as specified in Section 10.02 (such period, the “Cash Settlement Notice Period”). If the Company elects to pay cash for any portion of the shares otherwise issuable to the Holder,
the Holder may retract the Notice of Conversion at any time during the two Business Day period beginning on the day after the final day of the Cash Settlement Notice Period (the “Conversion Retraction Period”); no such retraction
can be made (and a Notice of Conversion shall be irrevocable) if the Company does not elect to deliver cash in lieu of shares of Common Stock (other than cash in lieu of fractional shares). With respect to any Notice of Conversion received by the

  

 60 

 Company prior to the Final Notice Date, the “Conversion Settlement Distribution” for any Security
subject to such Notice of Conversion shall consist of cash, Common Stock or a combination thereof, as selected by the Company as set forth below: 
  
 (i) if the Company elects to satisfy the entire Conversion Obligation in shares of Common Stock, the Conversion Settlement Distribution
shall be a number of shares equal to (1) the aggregate principal amount of the Securities to be converted divided by 1,000, multiplied by (2) the sum of the Conversion Rate (or, if the Conversion Date occurs at a time when the Holder holds Transfer
Restricted Securities (as defined in the Registration Rights Agreement) and there exists a Registration Default (as defined in the Registration Rights Agreement) affecting the Holder’s Transfer Restricted Securities (as defined in the
Registration Rights Agreement), in lieu of Liquidated Damages, for the purposes of this Section 10.03(a)(i) and Section 10.03(a)(iii), such Conversion Rate will be multiplied by 103%) and the number of Additional Shares, if any, pursuant to Section
10.01(c) above; 
  
 (ii) if the Company elects to
satisfy the entire Conversion Obligation in cash, the Conversion Settlement Distribution shall be cash in an amount equal to the product of: 
  
 (A) a number equal to the product of (x) the aggregate principal amount of Securities to be converted divided by 1,000 multiplied by (y)
the sum of the Conversion Rate and the number of Additional Shares, if any, pursuant to Section 10.01(c) above, and 
  
 (B) the average Last Reported Sale Price of the Common Stock during the Trading Days in the Cash Settlement Averaging Period; and

  
 (iii) if the Company elects to satisfy a
fixed portion (other than 100%) of the Conversion Obligation in cash, the Conversion Settlement Distribution shall consist of such cash amount (“Cash Amount”) and a number of shares equal to the greater of (1) zero and (2) the
excess, if any, of the number of shares calculated as set forth in clause (i) above over the number of shares equal to the sum, for each day of the Cash Settlement Averaging Period, of (x) 5% (or, if a Holder elects to convert Securities pursuant to
Section 10.01(b) and is entitled to Additional Shares pursuant to Section 10.01(c), then 20%) of the Cash Amount, divided by (y) the Last Reported Sale Price of the Common Stock on such day. 
  
 (b) At any time on or before any Final Notice Date, the Company will notify
the Trustee if it intends to satisfy all or any portion of the Conversion Obligation with respect to conversions of Securities for which the Company 
  

 61 

 receives a Notice of Conversion after such Final Notice Date in cash and the dollar amount to be satisfied in cash (which
must be expressed either as 100% or as a fixed dollar amount). In such case, such Notice of Conversion will not be retractable and the applicable Conversion Settlement Distribution will be computed in the same manner as set forth in clause (a) above
except that the Cash Settlement Averaging Period shall be the 10 Trading Days beginning on the first day following the Company’s receipt of the Notice of Conversion. If the Company elects not to satisfy all or any portion of the Conversion
Obligation in cash, then the Conversion Settlement Distribution will be on the third Business Day following the Conversion Date. 
  
 (c) Notwithstanding anything to the contrary in this Indenture, at any time prior to Stated Maturity, the Company may irrevocably elect, in its sole
discretion without the consent of the Holders, by notice to the Trustee and the Holders, to satisfy the Conversion Obligation in cash by paying 100% of the principal amount of the Securities converted after the date of such election. After making
such election, the Company shall satisfy the remainder of the Conversion Obligation to the extent it exceeds the principal amount in Common Stock. Settlement amounts shall be computed and settlement dates shall be determined in the same manner as
set forth above under clause (a); provided that (i) notice of the election to deliver cash for the principal amount will be deemed to have been provided on the last date of the Cash Settlement Notice Period and the Company will not be
required to make any further election prior to the Final Notice Date (and will not deliver any further notice thereof following the Conversion Date); (ii) the Notice of Conversion will not be retractable; (iii) the Cash Settlement Averaging Period
shall be the 20 Trading Days beginning on the first day following the Company’s receipt of the Notice of Conversion; and (iv) the Cash Amount shall be the lesser of (A) (x) the number of shares of Common Stock, calculated as set forth above in
clause (a)(i) multiplied by (y) the average Last Reported Sale Price during the Cash Settlement Averaging Period and (B) 100% of the principal amount of a Security. 
  
 Section 10.04. Adjustment of Conversion Rate. The Conversion Rate shall be adjusted (without duplication) from time
to time by the Company as follows: 
  
 (a) In case the Company
shall hereafter pay a dividend or make a distribution to all holders of the outstanding Common Stock in shares of Common Stock, the Conversion Rate shall be increased so that the same shall equal the rate determined by dividing the Conversion Rate
in effect at the opening of business on the date following the date fixed for the determination of stockholders entitled to receive such dividend or other distribution by a fraction, 
  
 (i) the numerator of which shall be the number of shares of the Common Stock outstanding at the close of
business on the date fixed for such determination; and 
  

 62 

 (ii) the denominator of which shall be the sum of such number of shares and the total
number of shares constituting such dividend or other distribution, 
  
 such
increase to become effective immediately after the opening of business on the day following the date fixed for such determination. For the purpose of this paragraph (a), the number of shares of Common Stock at any time outstanding shall not include
shares held in the treasury of the Company. The Company will not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company. If any dividend or distribution of the type described in this Section 10.04(a)
is declared but not so paid or made, the Conversion Rate shall again be adjusted to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. 
  
 (b) In case the Company shall issue rights or warrants (other than pursuant
to any dividend reinvestment or share purchase plan) to all holders of its outstanding shares of Common Stock entitling them (for a period expiring within 60 days after the date of such issuance) to subscribe for or purchase shares of Common Stock
at a price per share less than the Last Reported Price on the date fixed for determination of stockholders entitled to receive such rights or warrants, the Conversion Rate shall be adjusted so that the same shall equal the rate determined by
dividing the Conversion Rate in effect immediately prior to the date fixed for determination of stockholders entitled to receive such rights or warrants by a fraction, 
  
 (i) the numerator of which shall be the number of shares of Common Stock outstanding at the close of
business on the date of issuance of such rights or warrants plus the number of shares that the aggregate offering price of the total number of shares so offered would purchase at such Last Reported Sale Price, and 
  
 (ii) the denominator of which shall be the number of shares
of Common Stock outstanding on the date of issuance of such rights or warrants plus the total number of additional shares of Common Stock offered for subscription or purchase. 
  
 Such adjustment shall be successively made whenever any such rights or warrants are issued, and shall become effective
immediately after the opening of business on the day following the date of issuance of such rights or warrants. To the extent that shares of Common Stock are not delivered after the expiration of such rights or warrants, the Conversion Rate shall be
readjusted to the Conversion Rate that would then be in effect had the adjustments made upon the issuance of such rights or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered. In the event
that such rights or warrants are not so issued, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such date fixed for the determination of stockholders entitled to receive such rights or warrants
had not 
  

 63 

 been fixed. In determining whether any rights or warrants entitle the holders to subscribe for or purchase shares of
Common Stock at less than such Last Reported Sale Price, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration received by the Company for such rights or warrants and any
amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors. 
  
 (c) In case outstanding shares of Common Stock shall be subdivided into a greater number of shares of Common Stock, the Conversion Rate in effect at the
opening of business on the day following the day upon which such subdivision becomes effective shall be proportionately increased, and conversely, in case outstanding shares of Common Stock shall be combined into a smaller number of shares of Common
Stock, the Conversion Rate in effect at the opening of business on the day following the day upon which such combination becomes effective shall be proportionately reduced, such increase or reduction, as the case may be, to become effective
immediately after the opening of business on the day following the day upon which such subdivision or combination becomes effective. 
  
 (d) In case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock shares of any class of Capital Stock of the
Company, debt securities, assets or rights or warrants to purchase securities of the Company (excluding (x) any dividend or distribution paid exclusively in cash or (y) any dividend, distribution or issuance referred to in Section 10.04(a) or (b))
(any of the foregoing hereinafter in this Section 10.04(d) called the “Distributed Assets”), then, in each such case, the Conversion Rate shall be adjusted so that the same shall be equal to the rate determined by multiplying the
Conversion Rate in effect on the Record Date with respect to such distribution by a fraction, 
  
 (i) the numerator of which shall be the Current Market Price per share of the Common Stock on such Record Date plus the Fair Market Value,
as determined by the Board of Directors, of the portion of those assets, debt securities, shares of any class of Capital Stock of the Company or rights or warrants so distributed applicable to one share of Common Stock; and 
  
 (ii) the denominator of which shall be the Current Market
Price per share of the Common Stock on the Record Date, 
  
 such adjustment to
become effective immediately prior to the opening of business on the day following such Record Date; provided, however, that in the event (1) the then Fair Market Value (as so determined) of the portion of the Distributed Assets so
distributed applicable to one share of Common Stock is equal to or greater than the Current Market Price of the Common Stock on the Record Date or (2) the Current Market Price of the Common Stock on the Record Date exceeds the then Fair Market Value
(as so determined) of the portion of the Distributed Assets so distributed applicable to one share of Common Stock by less than $1.00, 
  

 64 

 in lieu of the foregoing adjustment, adequate provision shall be made so that each Holder shall have the right to receive
upon conversion the amount of Distributed Assets such holder would have received had such holder converted each Security on the Record Date. In the event that such dividend or distribution is not so paid or made, the Conversion Rate shall again be
adjusted to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. 
  
 Rights or warrants distributed by the Company to all holders of Common Stock entitling the holders thereof to subscribe for or purchase shares of the
Company’s Capital Stock (either initially or under certain circumstances), which rights or warrants, until the occurrence of a specified event or events (“Trigger Event”): (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 10.04 (and no adjustment to the Conversion Rate under this
Section 10.04 will be required) until the occurrence of the earliest Trigger Event, whereupon such rights 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 this Section 10.04(d). If any such right or warrant, including any such existing rights or warrants distributed prior to the date of this Indenture, are subject to events, upon the occurrence of which such rights or warrants become exercisable
to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and record date with respect to new rights or warrants with such
rights (and a termination or expiration of the existing rights or warrants without exercise by any of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of rights or warrants, or any Trigger Event or other
event (of the type described in the preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Rate under this Section 10.04 was made, (1) in the case of any
such rights or warrants that shall all have been redeemed or repurchased without exercise by any holders thereof, the Conversion Rate shall be readjusted upon such final redemption or repurchase to give effect to such distribution or Trigger Event,
as the case may be, as though it were a cash distribution, equal to the per share redemption or repurchase price received by a holder or holders of Common Stock with respect to such rights or warrants (assuming such holder had retained such rights
or warrants), made to all holders of Common Stock as of the date of such redemption or repurchase, and (2) in the case of such rights or warrants that shall have expired or been terminated without exercise by any holders thereof, the Conversion Rate
shall be readjusted as if such rights and warrants had not been issued. 
  
 No adjustment of the Conversion Rate shall be made pursuant to this Section 10.04(d) in respect of rights or warrants distributed or deemed distributed on any Trigger Event to the extent that such rights or warrants are actually
distributed, or reserved by the Company for distribution to holders of Securities upon conversion by such holders of Securities to Common Stock. 
  

 65 

 For purposes of this Section 10.04(d) and Sections 10.04(a) and (b), any dividend or distribution to
which this Section 10.04(d) is applicable that also includes shares of Common Stock, or rights or warrants to subscribe for or purchase shares of Common Stock (or both), shall be deemed instead to be (1) a dividend or distribution of debt
securities, assets or shares of capital stock other than such shares of Common Stock or rights or warrants (and any Conversion Rate adjustment required by this Section 10.04(d) with respect to such dividend or distribution shall then be made)
immediately followed by (2) a dividend or distribution of such shares of Common Stock or such rights or warrants (and any further Conversion Rate adjustment required by Sections 10.04(a) and (b) with respect to such dividend or distribution shall
then be made), except (A) the Record Date of such dividend or distribution shall be substituted as “the date fixed for the determination of stockholders entitled to receive such dividend or other distribution”, “the date fixed for the
determination of stockholders entitled to receive such rights or warrants” and “the date fixed for such determination” within the meaning of Sections 10.04(a) and (b), and (B) any shares of Common Stock included in such dividend or
distribution shall not be deemed “outstanding at the close of business on the date fixed for such determination” within the meaning of Section 10.04(a). 
  
 If any Distributed Assets requiring any adjustment pursuant to this Section 10.04(d) consists of the Capital Stock, or
similar equity interests in, a Subsidiary or other business unit of the Company, the Conversion Rate in effect immediately before the close of business on the Record Date fixed for determination of shareholders entitled to receive the distribution
shall instead be increased by multiplying the Conversion Rate then in effect by a fraction, (A) the numerator of which is the sum of (1) the average of the Last Reported Sale Prices of such distributed security for the 20 Trading Days commencing on
and including the fifth Trading Day after the Ex-Dividend Date on the Nasdaq National Market or such other national or regional exchange or market on which the securities are then listed or quoted, plus (2) the average of the Last Reported Sale
Prices of the Common Stock over the same Trading Day period and (B) the denominator of which is such average of the Last Reported Sale Prices of the Common Stock. 
  
 (e) In case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock cash (an
“Extraordinary Cash Dividend”) (excluding (i) any dividend or distribution on the Common Stock paid after July 15, 2009 to the extent that the aggregate amount of such payment per share of Common Stock in any twelve month period
does not exceed 5% of the average of the Last Reported Sale Prices of the Common Stock during the 10 Trading Days immediately prior to the declaration date for such dividend or distribution (the “Dividend Threshold Amount”) and (ii)
any dividend or distribution in connection with the liquidation, dissolution or winding up of the Company, whether voluntary or involuntary), then, in such case, the Conversion Rate shall 
  

 66 

 be adjusted so that the same shall equal the rate determined by multiplying the Conversion Rate in effect immediately
prior to the close of business on the Record Date for such Extraordinary Cash Dividend by a fraction, 
  
 (i) the numerator of which shall be the Current Market Price of the Common Stock on such Record Date plus the amount of cash so
distributed applicable to one share of Common Stock, and 
  
 (ii) the denominator of which shall be such Current Market Price of the Common Stock, 
  
 such adjustment to be effective immediately prior to the opening of business on the day following the Record Date; provided, however, that in the event the portion
of cash so distributed applicable to one share of Common Stock is equal to or greater than the Current Market Price of the Common Stock on the Record Date, in lieu of the foregoing adjustment, adequate provision shall be made so that each Holder
shall have the right to receive upon conversion the amount of cash such holder would have received had such holder converted each Security on the Record Date. In the event that such dividend or distribution is not so paid or made, the Conversion
Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. 
  
 If an adjustment is required to be made under this Section 10.04(e) after July 15, 2009 as a result of a distribution that is a dividend, the adjustment shall be based
upon the amount by which the distribution exceeds the Dividend Threshold Amount. If an adjustment is required to be made under this Section 10.04(e) as a result of a distribution that is not a dividend, the adjustment shall be based upon the full
amount of such distribution. 
  
 (f) In case a tender or exchange
offer made by the Company or any Subsidiary for all or any portion of the Common Stock shall expire and such tender or exchange offer (as amended upon the expiration thereof) shall require the payment to stockholders of consideration per share of
Common Stock having a Fair Market Value (as determined by the Board of Directors) that as of the last time (the “Expiration Time”) tenders or exchanges may be made pursuant to such tender or exchange offer (as it may be amended)
exceeds the Last Reported Sale Price of the Common Stock on the Trading Day next succeeding the Expiration Time, the Conversion Rate shall be adjusted so that the same shall equal the rate determined by multiplying the Conversion Rate in effect
immediately prior to the Expiration Time by a fraction 
  
 (i) the numerator of which shall be the sum of (x) the Fair Market Value (determined by the Board of Directors) of the aggregate consideration payable to stockholders based on the acceptance (up to any maximum specified in the terms of the
tender or exchange offer) of all shares validly tendered or exchanged and not withdrawn as of the Expiration Time (the shares deemed so accepted up to any such maximum, 
  

 67 

 being referred to as the “Purchased Shares”) and (y) the product of the number of shares
of Common Stock outstanding (less any Purchased Shares) at the Expiration Time and the Last Reported Sale Price of the Common Stock on the Trading Day next succeeding the Expiration Time, and 
  
 (ii) the denominator of which shall be the number of shares
of Common Stock outstanding (including any Purchased Shares) at the Expiration Time multiplied by Last Reported Sale Price of the Common Stock on the Trading Day next succeeding the Expiration Time, 
  
 such adjustment to become effective immediately prior to the opening of business on the day
following the Expiration Time. In the event that the Company is obligated to purchase shares pursuant to any such tender or exchange offer, but the Company is permanently prevented by applicable law from effecting any such purchases or all such
purchases are rescinded, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such tender or exchange offer had not been made. 
  
 (g) The Company, from time to time, may, to the extent permitted by applicable law and the listing requirements of the
Nasdaq National Market (and any other exchange on which shares of the Common Stock are then listed), make such increases in the Conversion Rate, in addition to those required by this Section 10.04 as the Board of Directors considers to be advisable
to avoid or diminish any income tax to holders of Common Stock or rights to purchase shares of Common Stock resulting from any dividend or distribution of Capital Stock (or rights to acquire stock) or from any event treated as such for income tax
purposes. 
  
 To the extent permitted by applicable law and the
listing requirements of the Nasdaq National Market (and any other exchange on which shares of Common Stock are then listed), the Company from time to time may increase the Conversion Rate by any amount for any period of time if the period is at
least twenty (20) Business Days and the Board of Directors shall have made a determination that such increase would be in the best interests of the Company, which determination shall be conclusive. Whenever the Conversion Rate is increased pursuant
to the preceding sentence, the Company shall mail to holders of record of the Securities a notice of the increase at least fifteen (15) days prior to the date the increased Conversion Rate takes effect, and such notice shall state the increased
Conversion Rate and the period during which it will be in effect. 
  
 (h) All calculations under this Article 10 shall be made by the Company and shall be made to the nearest cent or to the nearest one-ten thousandth of a share, as the case may be, with one half-cent and 0.00005 of a share, respectively,
being rounded upward. No adjustment need be made for: 
  
 (i) the issuance of any shares of Common Stock pursuant to any present or future plan providing for the reinvestment of dividends or interest payable on securities of the Company and the investment of additional optional amounts in shares
of Common Stock under any plan, 
  

 68 

 (ii) the issuance of any shares of Common Stock or options or rights to purchase those
shares pursuant to any present or future employee, director or consultant benefit plan or program of or assumed by the Company or any of its Subsidiaries, 
  
 (iii) the issuance of any shares of Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible
security not described in clause (ii) above and outstanding as of the date the Securities were first issued, 
  
 (iv) a change in the par value of the Common Stock, 
  
 (v) the issuance of any shares of Common Stock pursuant to conversion of the Securities, or 
  
 (vi) accrued and unpaid Interest, including Liquidated
Damages, if any. 
  
 To the extent the Securities become
convertible into cash, assets, property or securities (other than Capital Stock of the Company), no adjustment need be made thereafter as to the cash, assets, property or such securities. 
  
 (i) Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly file with the Trustee and any
conversion agent other than the Trustee an Officers’ Certificate setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Unless and until a Responsible Officer of the
Trustee shall have received such Officers’ Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume that the last Conversion Rate of which it has knowledge is still in effect.
Promptly after delivery of such certificate, the Company shall prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted Conversion Rate and the date on which each adjustment becomes effective and shall mail such notice
of such adjustment of the Conversion Rate to the holder of each Security at his last address appearing on the Security register provided for in Section 2.03 of this Indenture, within twenty (20) days after execution thereof. Failure to deliver such
notice shall not affect the legality or validity of any such adjustment. 
  
 (j) In any case in which this Section 10.04 provides that an adjustment shall become effective immediately after (1) a record date or Record Date for an event, (2) the date fixed for the determination of stockholders
entitled to receive a dividend or distribution pursuant to Section 10.04(a), (3) a date fixed for the determination of stockholders entitled to receive rights or warrants pursuant to Section 10.04(b), or (4) the Expiration Time for any tender or
exchange offer 
  

 69 

 pursuant to Section 10.04(f) (each a “Determination Date”), the Company may elect to defer until the
occurrence of the relevant Adjustment Event (as hereinafter defined) (x) issuing to the holder of any Security converted after such Determination Date and before the occurrence of such Adjustment Event, the additional shares of Common Stock or other
securities issuable upon such conversion by reason of the adjustment required by such Adjustment Event over and above the Common Stock issuable upon such conversion before giving effect to such adjustment and (y) paying to such holder any amount in
cash in lieu of any fraction pursuant to Section 10.04(a). For purposes of this Section 10.04(j), the term “Adjustment Event” shall mean: 
  
 (i) in any case referred to in clause (1) hereof, the occurrence of such event, 
  
 (ii) in any case referred to in clause (2) hereof, the date
any such dividend or distribution is paid or made, 
  
 (iii) in any case referred to in clause (3) hereof, the date of expiration of such rights or warrants, and 
  
 (iv) in any case referred to in clause (4) hereof, the date a sale or exchange of Common Stock pursuant to such tender or exchange offer
is consummated and becomes irrevocable. 
  
 (k) For purposes of
this Section 10.04, the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of
Common Stock. The Company will not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company. 
  
 (l) If rights or warrants for which an adjustment has been made pursuant to the provisions of this Section 10.04 expire unexercised, the Conversion Rate
shall be readjusted as if such unexercised rights or warrants had not been issued. 
  
 (m) Notwithstanding the foregoing provisions of this Section 10.04, no adjustment shall be made thereunder, nor shall an adjustment be made to the ability of a Holder of a Security to convert, for any distribution
described therein if the Holder will otherwise participate in the distribution without conversion of such Holder’s Securities. 
  
 (n) Notwithstanding the foregoing provisions of this Section 10.04, in the event of an adjustment pursuant to Section 10.04(d), (e), or (f), in no event
will the total number of shares of Common Stock issuable upon conversion exceed 124.3781 per $1,000 principal amount of Securities, subject to adjustments pursuant to the provisions of Section 10.04(a), (b) and (c). 
  

 70 

 Section 10.05. Effect of Reclassification; Consolidation; Merger or Sale. If any of the following
events occur, namely (a) any reclassification or change of the outstanding shares of Common Stock (other than a subdivision or combination to which Section 10.04(c) applies), (b) any consolidation, merger, statutory share exchange or combination of
the Company with another Person as a result of which holders of Common Stock shall be entitled to receive stock, other securities or other property or assets (including cash) with respect to or in exchange for such Common Stock, or (c) any sale or
conveyance of all or substantially all the properties and assets of the Company to any other Person as a result of which holders of Common Stock shall be entitled to receive stock, other securities or other property or assets (including cash) with
respect to or in exchange for such Common Stock, then the Company or the successor or purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture (which shall comply with the TIA as in force at the date of
execution of such supplemental indenture) providing that each Security shall be convertible, subject to the provisions of Section 10.03, into the kind and amount of shares of stock, other securities or other property or assets (including cash)
receivable upon such reclassification, change, consolidation, merger, statutory share exchange, combination, sale or conveyance by a holder of a number of shares of Common Stock issuable upon conversion of such Securities (assuming, for such
purposes, a sufficient number of authorized shares of Common Stock are available to convert all such Securities) immediately prior to such reclassification, change, consolidation, merger, statutory share exchange, combination, sale or conveyance
assuming such holder of Common Stock did not exercise his rights of election, if any, as to the kind or amount of stock, other securities or other property or assets (including cash) receivable upon such reclassification, change, consolidation,
merger, statutory share exchange, combination, sale or conveyance (provided that, if the kind or amount of stock, other securities or other property or assets (including cash) receivable upon such reclassification, change, consolidation,
merger, statutory share exchange, combination, sale or conveyance is not the same for each share of Common Stock in respect of which such rights of election shall not have been exercised (“nonelecting share”), then for the purposes
of this Section 10.05 the kind and amount of stock, other securities or other property or assets (including cash) receivable upon such reclassification, change, consolidation, merger, statutory share exchange, combination, sale or conveyance for
each nonelecting share shall be deemed to be the kind and amount so receivable per share by a plurality of the nonelecting shares). Such supplemental indenture shall provide for adjustments which shall be as nearly equivalent as may be practicable
to the adjustments provided for in this Article 10. 
  
 The
Company shall cause notice of the execution of such supplemental indenture to be mailed to each holder of Securities, at its address appearing on the Security register provided for in Section 2.03 of this Indenture, within twenty (20) days after
execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture. 
  

 71 

 The above provisions of this Section shall similarly apply to successive reclassifications, changes,
consolidations, mergers, statutory share exchanges, combinations, sales and conveyances. 
  
 If this Section 10.05 applies to any event or occurrence, Section 10.04 shall not apply. 
  
 Section 10.06. Taxes on Shares Issued. The issue of stock certificates on conversions of Securities shall be made without charge to the converting
Holder for any tax in respect of the issue thereof. The Company shall not, however, be required to pay any tax which may be payable in respect of any transfer involved in the issue and delivery of stock in any name other than that of the holder of
any Securities converted, and the Company shall not be required to issue or deliver any such stock certificate unless and until the Person or Persons requesting the issue thereof shall have paid to the Company the amount of such tax or shall have
established to the satisfaction of the Company that such tax has been paid. 
  
 Section 10.07. Reservation of Shares, Shares to be Fully Paid; Compliance with Governmental Requirements; Listing of Common Stock. 
  
 (a) The Company shall provide, free from preemptive rights, out of its authorized but unissued shares or shares held in
treasury, sufficient shares of Common Stock to provide for the conversion of the Securities from time to time as such Securities are presented for conversion. 
  

(b) Before taking any action which would cause an adjustment increasing the Conversion Rate to an amount that would cause the Conversion Price to be
reduced below the then par value, if any, of the shares of Common Stock issuable upon conversion of the Securities, the Company will take all corporate action which may, in the opinion of its counsel, be necessary in order that the Company may
validly and legally issue shares of such Common Stock at such adjusted Conversion Rate. 
  
 (c) (i) The Company covenants that all shares of Common Stock which may be issued upon conversion of Securities or in payment of the Repurchase Price or the Change of Control Repurchase Price will upon issue be fully
paid and non-assessable by the Company and free from all taxes, liens and charges with respect to the issue thereof. 
  
 (ii) The Company covenants that, if any shares of Common Stock to be provided for the purpose of conversion of Securities hereunder
require registration with or approval of any governmental authority under any federal or state law before such shares may be validly issued upon conversion, the Company will in good faith and as expeditiously as possible, to the extent then
permitted by the rules and interpretations of the Securities and Exchange Commission (or any successor thereto), endeavor to secure such registration or approval, as the case may be. 
  

 72 

 (iii) The Company further covenants that, if at any time the Common Stock shall be listed
on the NYSE or any other national securities exchange or automated quotation system, the Company will, if permitted by the rules of such exchange or automated quotation system, list and keep listed, so long as the Common Stock shall be so listed on
such exchange or automated quotation system, all Common Stock issuable upon conversion of the Security; provided, however, that, if the rules of such exchange or automated quotation system permit the Company to defer the listing of such
Common Stock until the first conversion of the Securities into Common Stock in Common Stock in accordance with the provisions of this Indenture, the Company covenants to list such Common Stock issuable upon conversion of the Securities in accordance
with the requirements of such exchange or automated quotation system at such time. 
  
 Section 10.08. Responsibility of Trustee. The Trustee and any other conversion agent shall not at any time be under any duty or responsibility to any holder of Securities to determine the Conversion Rate or
whether any facts exist which may require any adjustment of the Conversion Rate, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental
indenture provided to be employed, in making the same. The Trustee and any other conversion agent shall not be accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of any securities or property,
which may at any time be issued or delivered upon the conversion of any Security; and the Trustee and any other conversion agent make no representations with respect thereto. Neither the Trustee nor any conversion agent shall be responsible for any
failure of the Company to issue, transfer or deliver any shares of Common Stock or stock certificates or other securities or property or cash upon the surrender of any Security for the purpose of conversion or to comply with any of the duties,
responsibilities or covenants of the Company contained in this Article 10. Without limiting the generality of the foregoing, neither the Trustee nor any conversion agent shall be under any responsibility to determine the correctness of any
provisions contained in any supplemental indenture entered into pursuant to Section 10.05 relating either to the kind or amount of shares of stock or securities or property (including cash) receivable by Holders upon the conversion of their
Securities after any event referred to in such Section 10.05 or to any adjustment to be made with respect thereto, but, subject to the provisions of Section 7.01, may accept as conclusive evidence of the correctness of any such provisions, and shall
be protected in relying upon, the Officers’ Certificate (which the Company shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto. 
  

 73 

 Section 10.09. Notice To Holders Prior To Certain Actions. In case: 
  
 (a) the Company shall declare a dividend (or any other
distribution) on its Common Stock that would require an adjustment in the Conversion Rate pursuant to Section 10.04; or 
  
 (b) the Company shall authorize the granting to the holders of all or substantially all of its Common Stock of rights or warrants to
subscribe for or purchase any share of any class or any other rights or warrants; or 
  
 (c) of any reclassification or reorganization of the Common Stock of the Company (other than a subdivision or combination of its
outstanding Common Stock, or a change in par value, or from par value to no par value, or from no par value to par value), or of any consolidation, merger or statutory share exchange to which the Company is a party and for which approval of any
stockholders of the Company is required, or of the sale or transfer of all or substantially all of the assets of the Company; or 
  
 (d) of the voluntary or involuntary dissolution, liquidation or winding up of the Company; 
  
 the Company shall cause to be filed with the Trustee and to be mailed to each Holder of
Securities at his address appearing on the register provided for in Section 2.03 of this Indenture, as promptly as possible but in any event at least ten (10) days prior to the applicable date hereinafter specified, a notice stating (x) the date on
which a record is to be taken for the purpose of such dividend, distribution of rights or warrants, or, if a record is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such dividend, distribution or
rights are to be determined, or (y) the date on which such reclassification, consolidation, merger, or statutory share exchange, sale, transfer, dissolution, liquidation or winding up is expected to become effective or occur, and the date as of
which it is expected that holders of Common Stock of record shall be entitled to exchange their Common Stock for securities or other property deliverable upon such reclassification, consolidation, merger, or statutory share exchange, sale, transfer,
dissolution, liquidation or winding up. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such dividend, distribution, reclassification, consolidation, merger, or statutory share exchange, sale,
transfer, dissolution, liquidation or winding up. 
  
 Section
10.10. Rights Issued in Respect of Common Stock Issued upon Conversion. To the extent the Company has a rights plan that is in effect upon a Conversion Date, Holders of Securities shall receive, upon conversion of Securities, in addition to
shares of Common Stock, cash, or combination of cash and shares of Common Stock, the rights under the applicable rights plan unless, prior to the Conversion Date, the rights have separated from the Common Stock, in which case the Conversion Rate in
effect shall be adjusted at the time of separation as if the Company had distributed to all holders of Common Stock the assets, debt securities, shares of Capital Stock or rights or warrants to purchase securities of the Company as described in
Section 10.04(d). 
  

 74 

 Section 10.11. Unconditional Rights of Holders to Convert. Notwithstanding any other provision in
this Indenture, the Holder of any Security shall have the right, which is absolute and unconditional, to convert its Security in accordance with this Article 10 and to bring an action for the enforcement of any such right to convert, and such rights
shall not be impaired or affected without the consent of such Holder.

 [FORM OF REVERSE OF GLOBAL SECURITY] 
  
 3.50% Convertible Senior Debentures Due 2024 
  
 This Security is one of a duly authorized issue of 3.50% Convertible Senior Debentures Due 2024 (the
“Securities”) of Allscripts Healthcare Solutions, Inc., a Delaware corporation (including any successor corporation under the Indenture hereinafter referred to, the “Company”), issued under an Indenture, dated as of
July 6, 2004 (the “Indenture”), between the Company and LaSalle Bank N.A., as trustee (the “Trustee”). The terms of the Security include those stated in the Indenture, those made part of the Indenture by reference
to the Trust Indenture Act of 1939, as amended (“TIA”), and those set forth in this Security. This Security is subject to all such terms, and Holders are referred to the Indenture and the TIA for a statement of all such terms. To
the extent permitted by applicable law, in the event of any inconsistency between the terms of this Security and the terms of the Indenture, the terms of the Indenture shall control. Capitalized terms used but not defined herein have the meanings
assigned to them in the Indenture referred to below unless otherwise indicated. 
  
 1. Interest. 
  
 The Securities shall bear
interest on the principal amount thereof at a rate of 3.50% per year. The Company shall pay Liquidated Damages as set forth in Section 4.07 of the Indenture and the Registration Rights Agreement. 
  
 Interest will be payable semi-annually on each Interest Payment Date to
Holders at the close of business on the preceding Interest Record Date. Interest will be computed on the basis of a 360-day year comprised of twelve 30 day months. 
  
 If any Interest Payment Date, Stated Maturity date, Redemption Date, Repurchase Date or Change of Control Repurchase Date of
a Security falls on a day that is not a Business Day, the required payment of Interest, if any, and principal will be made on the next succeeding Business Day and no Interest on such payment will accrue for the period from and after the Interest
Payment Date, the Stated Maturity date, Redemption Date, Repurchase Date or Change of Control Repurchase Date to such next succeeding Business Day. 
  
 If the principal amount of any Security, or any accrued and unpaid Interest or Liquidated Damages, if any, are not paid when due (whether upon
acceleration pursuant to Section 6.02 of the Indenture, upon the date set for payment of the Redemption Price pursuant to Section 5 hereof, upon the date set for payment of the Repurchase Price or Change of Control Repurchase Price pursuant to
Section 6 hereof, upon the Stated Maturity of the Securities, upon the Interest Payment Dates or upon the Liquidated Damages Payment Dates as defined in the Registration Rights Agreement), then in each such case the overdue amount shall, 

 

 A-5 

 to the extent permitted by law, bear cash interest at the rate of 2% per annum, compounded semiannually, which interest
shall accrue from the date such overdue amount was originally due to the date payment of such amount, including interest thereon, has been made or duly provided for. All such interest shall be payable in cash on demand but if not so demanded shall
be paid quarterly to the Holders on the last day of each quarter. 
  
 2. Method
of Payment. 
  
 Except as provided below, the Company shall
pay Interest on (i) Global Securities, to DTC in immediately available funds, (ii) any Certificated Security having an aggregate principal amount of $5,000,000 or less, by check mailed to the Holder of such Security and (iii) any Certificated
Security having an aggregate principal amount of more than $5,000,000, by wire transfer in immediately available funds or by mail at the election of the Holder of any such Security. 
  
 At Stated Maturity, the Company will pay Interest on Certificated Securities at the Company’s office or agency in
Illinois. 
  
 Subject to the terms and conditions of the
Indenture, the Company will make payments in cash in respect of Redemption Prices, Repurchase Prices, Change of Control Repurchase Prices and at Stated Maturity to Holders who surrender Securities to a Paying Agent to collect such payments in
respect of the Securities. The Company will pay cash amounts in money of the United States that at the time of payment is legal tender for payment of public and private debts. However, the Company may make such cash payments by check payable in such
money. 
  
 3. Indenture. 
  
 The Securities are general unsecured obligations of the Company limited to
$75,000,000 aggregate principal amount. The Indenture does not limit other indebtedness of the Company, secured or unsecured. 
  
 4. Redemption at the Option of the Company. 
  
 No sinking fund is provided for the Securities. The Securities are redeemable for cash at the option of the Company, in whole or in part, at any time or
from time to time on or after July 20, 2009 upon not less than 30 nor more than 60 days’ notice by mail for a redemption price equal to the principal amount of those Securities plus accrued and unpaid Interest and Liquidated Damages, if any, on
those Securities up to (but excluding) the Redemption Date (the “Redemption Price”). 
  
 In no event will any Security be redeemable before July 20, 2009. 
  

 A-6 

 5. 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 the Holder, all or any portion of the Securities held by such Holder on July 15, 2009, July 15, 2014, July 15, 2019, in integral multiples of $1,000 at a Repurchase Price equal to the principal amount
of those Securities plus accrued and unpaid Interest, and Liquidated Damages, if any, on those Securities up to (but excluding) the Purchase Date. To exercise such right, a Holder shall deliver to the Paying Agent a Purchase Notice containing the
information set forth in the Indenture, at any time from the opening of business on the date that is 20 Business Days prior to such Purchase Date until the close of business on such Purchase Date, and shall deliver the Securities to the Paying Agent
as set forth in the Indenture. 
  
 At the option of the Holder and
subject to the terms and conditions of the Indenture, the Company shall become obligated to purchase the Securities held by such Holder after the occurrence of a Change of Control for a Change of Control Repurchase Price equal to the principal
amount of those Securities plus accrued and unpaid Interest and Liquidated Damages, if any, on those Securities up to (but excluding) the Change of Control Repurchase Date. 
  
 Holders have the right to withdraw any Repurchase Notice or Change of Control Repurchase Notice, as the case may be, by
delivering to the Paying Agent a written notice of withdrawal in accordance with the provisions of the Indenture. 
  
 If cash sufficient to pay the Repurchase Price or Change of Control Repurchase Price, as the case may be, of all Securities or portions thereof to be
purchased as of the Repurchase Date or the Change of Control Repurchase Date, as the case may be, is deposited with the Paying Agent, on the Business Day immediately following the Repurchase Date or the Change of Control Repurchase Date, Interest
and Liquidated Damages, if any, will cease to accrue on such Securities (or portions thereof) on and following such Repurchase Date or Change of Control Repurchase Date, and the Holder thereof shall have no other rights as such other than the right
to receive the Repurchase Price or Change of Control Repurchase Price upon surrender of such Security. 
  
 6. Notice of Redemption. 
  
 Notice of redemption pursuant to Section 4 of this Security will be mailed at least 30 days but not more than 60 days before the Redemption Date to each Holder of Securities to be redeemed at the Holder’s registered address. If money
sufficient to pay the Redemption Price of all Securities (or portions thereof) to be redeemed on the Redemption Date is deposited with the Paying Agent prior to or on the Redemption Date, on and immediately after such Redemption Date Interest and
Liquidated Damages, if any, will cease to accrue on such Securities or portions thereof. Securities in denominations larger than $1,000 principal amount may be redeemed in part but only in integral multiples of $1,000 of principal amount.

 7. Conversion. 
  
 Subject to and in compliance with the provisions of the Indenture (including, without limitation, the conditions to conversion of this Security set forth
in Section 10.01 thereof), a Holder is entitled, at such Holder’s option, to convert the Holder’s Security (or any portion of the principal amount thereof that is $1,000 or an integral multiple $1,000), into fully paid and nonassessable
shares of Common Stock at the Conversion Rate in effect at the time of conversion provided, however, the Company may satisfy its obligation with respect to any demand for conversion by delivering Common Stock, cash or a combination of cash
and Common Stock. 
  
 The Company will notify Holders of any event
triggering the right to convert the Securities as specified above in accordance with the Indenture. 
  
 A Security in respect of which a Holder has delivered a Purchase Notice or Change of Control Repurchase Notice, as the case may be, exercising the option
of such Holder to require the Company to purchase such Security may be converted only if such Repurchase Notice or Change of Control Repurchase Notice, as the case may be, is withdrawn in accordance with the terms of the Indenture. 
  
 The initial Conversion Rate is 88.8415 shares of Common Stock per $1,000
principal amount, subject to adjustment in certain events described in the Indenture. The Conversion Rate shall not be adjusted for any accrued and unpaid Interest and accrued or Liquidated Damages. Upon conversion, no payment shall be made by the
Company with respect to accrued and unpaid Interest. Instead, such amount shall be deemed paid by the shares of Common Stock delivered upon conversion of any Security. A Holder shall receive, however, accrued and unpaid Liquidated Damages, if any.
In addition, no payment or adjustment shall be made in respect of dividends on the Common Stock, except as set forth in the Indenture. 
  
 In certain circumstances as set forth in the Indenture, a Holder shall receive Additional Shares as set forth in Section 10.01 of the Indenture.

  
 To surrender a Security for conversion, a Holder must (1)
complete and manually sign the Notice of Conversion attached hereto (or complete and manually sign a facsimile of such notice) and deliver such notice to the Conversion Agent, (2) surrender the Security to the Conversion Agent, (3) furnish
appropriate endorsements and transfer documents, (4) if required by Section 10.02(g) of the Indenture, pay Interest and (5) pay any transfer or similar tax, if required. 
  

 A-8 

 No fractional shares of Common Stock shall be issued upon conversion of any Security. Instead of any
fractional share of Common Stock that would otherwise be issued upon conversion of such Security, the Company shall pay a cash adjustment as provided in the Indenture. 
  
 If the Company (i) is a party to a consolidation, merger, statutory share exchange or combination, (ii) reclassifies the
Common Stock, or (iii) conveys, transfers or leases its properties and assets substantially as an entirety to any Person, the right to convert a Security into shares of Common Stock may be changed into a right to convert it into securities, cash or
other assets of the Company or such other Person, in each case in accordance with the Indenture. 
  
 8. Conversion Arrangement on Call for Redemption. 
  
 Any Securities called for redemption, unless surrendered for conversion before the close of business on Redemption Date, may be deemed to be purchased from the Holders of such Securities at an amount not less than the
Redemption Price, by one or more investment bankers or other purchasers who may agree with the Company to purchase such Securities from the Holders, to convert them into shares of Common Stock and to make payment for such Securities to the Trustee
in trust for such Holders. 
  
 9. Paying Agent, Conversion Agent and Registrar.

  
 Initially, the Trustee will act as Paying Agent,
Conversion Agent and Registrar. The Company may appoint and change any Paying Agent, Conversion Agent or Registrar without notice, other than notice to the Trustee; provided that the Company will maintain at least one Paying Agent in the
State of Illinois, which shall initially be an office or agency of the Trustee. The Company or any of its Subsidiaries or any of their Affiliates may act as Paying Agent, Conversion Agent or Registrar. 
  
 10. Denominations; Transfer; Exchange. 
  
 The Securities are in fully registered form, without coupons, in
denominations of $1,000 of principal amount and integral multiples of $1,000. A Holder may transfer or exchange Securities in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements
and transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. The Registrar need not transfer or exchange any Securities selected for redemption (except, in the case of a Security to be redeemed in part, the
portion of the Security not to be redeemed) or any Securities in respect of which a Purchase Notice or Change of Control Repurchase Notice has been given and not withdrawn (except, in the case of a Security to be purchased in part, the portion of
the Security not to be purchased) or any Securities for a period of 15 days before the mailing of a notice of redemption of Securities to be redeemed. 
  

 A-9 

 11. Persons Deemed Owners. 
  
 The registered Holder of this Security may be treated as the owner of this Security for all purposes. 
  
 12. Unclaimed Money or Securities. 
  
 The Trustee and the Paying Agent shall return to the Company upon written
request any money or securities held by them for the payment of any amount with respect to the Securities that remains unclaimed for two years, subject to applicable unclaimed property law. After return to the Company, Holders entitled to the money
or securities must look to the Company for payment as general creditors unless an applicable abandoned property law designates another person. 
  
 13. Amendment; Waiver. 
  
 Subject to certain exceptions set forth in the Indenture, (i) the Indenture or the Securities may be amended with the written consent of the Holders of at
least a majority in aggregate principal amount of the outstanding Securities and (ii) certain Events of Defaults may be waived with the written consent of the Holders of a majority in aggregate principal amount of the outstanding Securities. Subject
to certain exceptions set forth in the Indenture, without the consent of any Securityholder, the Company and the Trustee may amend the Indenture or the Securities (i) to add guarantees with respect to the Securities or securing the Securities, (ii)
to add to the covenants of the Company or the Events of Default for the benefit of the Holders of Securities, (iii) to surrender any right or power conferred upon the Company in the Indenture, (iv) to provide for conversion rights of Holders of
Securities if any reclassification or change of the Company’s Common Stock or any consolidation, merger or sale of all or substantially all of the Company’s assets occurs, (v) to provide for the assumption of the Company’s obligations
to Holders of Securities in the case of a merger, consolidation, conveyance, transfer or lease pursuant to Article 5 of the Indenture, (vi) to increase the Conversion Rate; provided, however, that such increase in the Conversion Rate shall
not adversely affect the interests of the Holders of Securities, (vii) to establish the form of Securities if issued in definitive form, (viii) to evidence and provide for the acceptance of the appointment under the Indenture of a successor Trustee,
(ix) to comply with the requirements of the SEC in order to effect or maintain the qualification of the Indenture under the TIA, (x) make any changes or modifications necessary in connection with the registration of the Securities under the
Securities Act as contemplated in the Registration Rights Agreement; provided that such change or modification does not in the good faith opinion of the Board of Directors and the Trustee adversely affect the interests of the Holders of
Securities in any material respect, (xi) to cure any ambiguity or to correct or supplement any provision in the Indenture which may be inconsistent with any other provision in the Indenture or which is otherwise defective, provided, however,
that any such cure, correction or supplement shall not 
  

 A-10 

 adversely affect the interests of the Holders of Securities, provided further that any such cure, correction or
supplement made solely to conform the provisions of the Indenture to the “Description of the Debentures” in the Offering Memorandum relating to the Securities will not be deemed to adversely affect the interests of the Holders of
Securities, or (xii) add or modify any other provisions of the Indenture with respect to matters or questions arising under the Indenture that the Company and the Trustee may deem necessary or desirable and that will not materially adversely affect
the interests of the Holders of Securities; provided that any addition or modification made solely to conform the provisions of this Indenture to the “Description of Debentures” in the Offering Memorandum relating to the Securities
will not be deemed to adversely affect the interests of the holders of the Securities. 
  
 14. Defaults and Remedies. 
  
 If any Event of
Default with respect to Securities shall occur and be continuing, the principal amount of the Securities and any accrued and unpaid Interest and accrued and unpaid Liquidated Damages, if any, on all the Securities may be declared due and payable in
the manner and with the effect provided in the Indenture. 
  
 15. Trustee
Dealings with the Company. 
  
 Subject to certain limitations
imposed by the TIA, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Securities and may otherwise deal with and collect obligations owed to it by the Company or its Affiliates and may
otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee. 
  
 16. Calculations in Respect of Securities. 
  
 The Company or its agents will be responsible for making all calculations called for under the Securities including, but not limited to, determination of the market prices for the Securities and of the Common Stock
and Liquidated Damages, if any, accrued on the Securities. Any calculations made in good faith and without manifest error will be final and binding on Holders of the Securities. The Company or its agents will be required to deliver to the Trustee a
schedule of its calculations and the Trustee will be entitled to conclusively rely upon the accuracy of such calculations without independent verification. 
  
 17. [Reserved]. 
  
 18. [Reserved]. 
  
 19. No Recourse
Against Others.

shareholder, as such, of the Company shall not have any liability for any obligations of the Company under the 
  

 A-11 

 Securities or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation.
By accepting a Security, each Securityholder waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Securities.
