 All other TIA terms used in this Indenture that are defined by
the TIA, defined by TIA reference to another statute or defined by SEC rule have the meanings assigned to them by such definitions. 
  
 Section 1.4 Rules of Construction. Unless the context otherwise requires: 
  
 (1) a term has the meaning assigned to it; 
  
 (2) an accounting term not otherwise defined has the meaning assigned to it in accordance with U.S. generally accepted

 (3)
“or” is not exclusive; 
  
 (4) “including”

 (5) words in the

 Section 1.5 Acts of Holders. (a) Any request, demand, authorization, direction, notice, consent, waiver 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 10.2. 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 writing appointing any such agent shall be sufficient for any purpose of this Indenture and conclusive
in favor of the Trustee and the Company, if made in the manner provided in this Section. 
  
 (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

  

 6 

 
individual capacity, such certificate or affidavit shall also constitute sufficient proof of such signer’s authority. The fact and date of the execution
of any such instrument or writing, or the authority of the Person executing the same, may also be proved in any other manner that the Trustee deems sufficient. 
  

(c) The principal amount and serial number of any Security and the ownership of Securities shall be proved by the register for the Securities.

  
 (d) Any request, demand, authorization, direction, notice,
consent, waiver or other Act of the Holder of any Security shall bind every future Holder of the same Security and the Holder of every Security issued upon the registration of transfer thereof or in exchange 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.

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 2.1(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 2.1(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 pursuant to the Depositary’s instructions and (c) shall be substantially in the form of Exhibit A attached hereto; provided that the Legend (other than the first and second paragraphs
thereof) may be removed from such Global Security on satisfaction of the conditions specified in this Indenture. 
  
 (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; provided that the Legend may be removed from such Securities on satisfaction of the conditions specified in this Indenture. 
  

Section 2.2 Execution and Authentication. The Securities shall be executed on behalf of the Company by any Officer. The signature of the Officer
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 

  

 8 

 
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 $60,000,000 (up to $72,000,000 if the Initial Purchasers exercise their option to purchase up to $12,000,000 aggregate principal amount of
additional Securities) upon one or more Company Orders without any further action by the Company (other than as contemplated in Section 10.4 and Section 10.5 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 2.3 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 4.5. The term Conversion Agent includes any additional conversion agent,
including any named pursuant to Section 4.5. 
  
 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 7.7. 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, Paying Agent and
Conversion Agent in connection with the Securities. 
  
 Section
2.4 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) 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 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 so held in trust. If the Company, a Subsidiary or an 

  

 9 

 
Affiliate of either of them acts as Paying Agent, it shall segregate the money 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 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. 
  
 Section 2.5 Securityholder Lists. The Trustee shall preserve in as
current a form as is reasonably practicable the most recent list available to it of the names and addresses of Securityholders. If the Trustee is not the Registrar, the Company shall cause to be furnished to the Trustee at least semiannually on
January 1 and July 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
2.6 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 2.3, 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 Change of Control Purchase Notice has been given and not withdrawn by the Holder 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, (i) transfers of beneficial interests in a Global Security, in whole or in part, may be effected only through a book entry system maintained by the Holder of such Global
Security (or its agent) in accordance with Applicable Procedures, (ii) ownership of a beneficial interest in the Security shall be required to 

  

 10 

 
be reflected in book entry and (iii) transfers of Global Securities or beneficial interests in Global Securities shall be made only in accordance with
Section 2.12 and this Section 2.6(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 2.3 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 the Company and the Registrar such satisfactory evidence, which shall include an opinion of counsel, as may be reasonably required by the Company and the Registrar 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 of 1933, as amended (“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. 
  
 In the event Rule 144(k) as promulgated under the Securities Act is amended
to shorten the two-year period under Rule 144(k), then, the references in the Legend to “TWO YEARS”, and in the corresponding transfer restrictions described above, will be deemed to refer to such shorter period, from and after receipt by
the Trustee of an Officers’ Certificate and an Opinion of Counsel to that effect. As soon as practicable after the Company knows of the effectiveness of any such amendment to shorten the two-year period under Rule 144(k), unless such changes
would otherwise be prohibited by, or would cause a violation of, the federal securities laws applicable at the time, the Company will provide to the Trustee an Officers’ Certificate and an Opinion of Counsel as to the effectiveness of such
amendment and the effectiveness of such change to the restrictive legends and transfer restrictions.  
  

 11 

 Until the Legend on any Restricted Security has been removed in compliance with this Section 2.6(f), all
shares of Common Stock (or other securities issuable upon conversion as a result of the provisions of this Indenture) issued upon conversion of such Restricted Security shall bear a legend substantially in the form of the Legend (the “Common
Stock Restrictive Legend”) and shall be subject to the same restrictions on transfer as such Restricted Security. At any time following the time when the restrictions on transfer set forth in the Common Stock Restrictive Legend shall have
expired in accordance with their terms or shall have terminated under applicable law, the holder of such Common Stock may, upon a surrender of the certificate representing such Common Stock exchange to the Company’s transfer agent in accordance
with such agent’s customary procedures (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, addressed to the Company and in form acceptable to the Company, to the effect that the transfer of such Common Stock has been made in compliance with
Rule 144 or such successor provision), may receive a new certificate representing such Common Stock, in like amount, which shall not bear the Common Stock Restrictive Legend. 
  
 Section 2.7 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 2.7, 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 2.7 in lieu of any
mutilated, destroyed, lost or stolen Security shall constitute an original additional 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 2.7 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. 
  

 12 

 Section 2.8 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 2.7, those delivered to it for cancellation and those described in this Section 2.8 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 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 8). 
  
 If a Security is replaced pursuant to
Section 2.7, 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 following a Change of Control Purchase Date, or
on Stated Maturity, money sufficient to pay Securities payable on that date, then immediately after such Redemption Date, Change of Control Purchase Date or Stated Maturity, as the case may be, such Securities shall cease to be outstanding and
interest, including Additional Amounts, 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 9, then from and after the time of conversion on the date of conversion, such Security shall cease to be outstanding and interest, including Additional Amounts, if any, shall cease to accrue on such Security.

  
 Section 2.9 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 2.3, 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 

  

 13 

 
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. If the Company shall acquire any of the Securities, such acquisition shall not operate as a redemption or satisfaction
of the indebtedness represented by such Securities unless the same are delivered to the Trustee for cancellation. All Securities surrendered for payment, purchase by the Company pursuant to Article 3, conversion, redemption or registration of
transfer or exchange shall, if surrendered to any Person other than the Trustee, 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 9. 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 principal of the Security or the payment of any Redemption
Price or Change of Control Purchase Price in respect thereof, and interest 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 2.6 and Section 2.12(a)(i), (B) transfers or exchanges of a beneficial interest in a Global Security for an interest in the same or another Global Security shall comply with Section 2.6 and Section 2.12(a)(ii) below, (C) transfers of a
beneficial interest in a Global Security for a Certificated Security shall comply with Section 2.6, Section 2.12(a)(ii) below and Section 2.12(e)(1) below, and (D) transfers of a Certificated Security shall comply with Section 2.6 and Sections
2.12(a)(iv) and (v) below. 
  
 (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 (i) shall not prohibit any transfer of a Certificated Security that is issued in exchange for a Global Security. No transfer of a Global 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. 
  

 14 

 (ii) Transfer or Exchange of a Beneficial Interest in a Global Security for a
Beneficial Interest in the Same or Another Global Security. 
  
 (x) A beneficial interest in a Global Security may not be transferred or exchanged for a beneficial interest in another Global Security except upon satisfaction of the requirements set forth below. Upon receipt by the
Trustee of a request to transfer or exchange of a beneficial interest in a Global Security in accordance with Applicable Procedures for a beneficial interest in another Global Security, 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, in the case of a transfer or exchange of a beneficial interest in a Global Security for a beneficial interest in another Global Security, an adjustment on its books and records with respect to
such Global Securities to reflect a decrease and increase in the aggregate principal amount of the Securities represented by such Global Securities, such instructions to contain information regarding the Depositary accounts to be credited with such
decrease and increase; 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, (1) 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 appropriate Global Security to be decreased by the aggregate principal amount that the other Global Security is increased and (2) in accordance with
the standing instructions and procedures existing between the Depositary and the Registrar and Applicable Procedures, shall debit and credit or cause to be debited or credited, as appropriate, to the accounts of the persons specified in such
instructions a beneficial interest in the Global Security or Global Securities, as appropriate, equal to the amount of the beneficial interests so transferred or exchanged. 
  
 (y) Beneficial interests in a Global Security may be transferred to Persons who take delivery in the same
Global Security in accordance with the Applicable Procedures and, if the Global Security is a Restricted Security, in accordance with the transfer restrictions set forth in the Legend. No written orders or instructions shall be required to be
delivered to the Registrar or the Trustee to effect the transactions described in this Section 2.12(a)(ii)(y). 
  
 (z) Other than transfers to the Company or to an Affiliate of the Company, beneficial interests in a Global Security that is not a
Restricted Security 

  

 15 

 may not be transferred to Person who takes delivery thereof in the form a beneficial interest in a
Global Security that is a Restricted Security. 
  
 (iii) Transfer or Exchange 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)(1) 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. 
  
 (iv) 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: 

 

	 	(1)	 	 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 

  

 16 

	 	(2)	 	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 (A), (B) or (C) below, and are accompanied by the following additional information and documents, as applicable: 

  
 (A) 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 
  
 (B) if
such Certificated Securities are being transferred to the Company, a certification to that effect; or 
  
 (C) 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 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. 
  
 (v) 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: 
  
 (I) so long as the Securities are Restricted Securities, certification, in the form set forth in Exhibit C, that such Certificated Security is being
transferred to a QIB in accordance with Rule 144A, or to an institutional accredited investor within the meaning of Rule 501(a)(1), (2), (3) or (7) of Regulation D of the Securities Act; and 
  
 (II) 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 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 

  

 17 

 
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 the succeeding Section (c), every Security
shall be subject to the restrictions on transfer provided in the Legend and herein including the delivery of an opinion of counsel, if so provided. Whenever any Restricted Security is presented or surrendered for transfer or for exchange, 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 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, addressed to the Company and in form acceptable to the Company, to the effect that the transfer of such
Security has been made in compliance with Rule 144 or such successor provision), be exchanged for a new Security, of like tenor and aggregate principal amount, which shall not bear the restrictive Legend. The Company shall inform the Trustee of the
effective date of any registration statement registering the 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 interest in any Security. 
  
 (e) The provisions of clauses (1), (2), (3) and (4) below shall apply only to
Global Securities: 
  

	 	(1)	 	 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 

  

 18 

	 	 	 	for Securities registered in the names of any Person designated by the Depositary in the event that (i) the Depositary has notified the Company that it is unwilling or unable to
continue as Depositary for such Global Security or such Depositary has ceased to be a “clearing agency” registered under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and a successor Depositary is not
appointed by the Company within 90 days or (ii) an Event of Default has occurred and is continuing with respect to the Securities. Any Global Security exchanged pursuant to clause (i) above shall be so exchanged in whole and not in part, and any
Global Security exchanged pursuant to clause (ii) 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. 

  

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

  

	 	(3)	 	Subject to the provisions of clause (5) below, 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. 

  

	 	(4)	 	In the event of the occurrence of any of the events specified in clause (1) above, the Company will promptly make available to the Trustee a reasonable supply of Certificated
Securities in definitive, fully registered form, without interest coupons. 

  

	 	(5)	 	 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 

  

 19 

	 	 
Global Security registered in the name of the Depositary or any nominee thereof, or under any such Global Security, and the Depositary or such nominee, as
the case may be, may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner and holder of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent
the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or such nominee, as the case may be, or impair, as between the Depositary,
its Agent Members and any other Person on whose behalf an Agent Member may act, the operation of customary practices of such Persons governing the exercise of the rights of a holder of any Security. 

  
 (f) By its acceptance of any Security bearing the Legend, each Holder of such
Security acknowledges the restrictions on transfer of such Security set forth in this Indenture and agrees that it will transfer such Security only as provided in this Indenture. 
  
 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 III 
  
 REDEMPTION AND PURCHASES 
  
 Section 3.1
Company’s Right to Redeem; Notices to Trustee. Prior to July 20, 2006, the Securities will not be redeemable at the Company’s option. Beginning on July 20, 2006, the Company, at its option, may redeem the Securities, subject to and
in accordance with the terms and conditions of Section 5 of the Securities, for cash, as a whole or in part, at a redemption price equal to the principal amount of those Securities plus any accrued and unpaid interest, including Additional Amounts,
if any, on those Securities to the Redemption Date. If the Company elects to redeem Securities pursuant to Section 5 of the Securities, it shall notify the Trustee in writing of the Redemption Date, the principal amount of Securities to be redeemed
and the Redemption Price. 
  
 The Company shall give the
notice to the Trustee of its intention to exercise its right to redeem the Securities as provided for in this Section 3.1 by a Company Order at least ten (10) Business Days prior to the day the Redemption Notice is to be mailed.

  
 Section 3.2 Selection of Securities to Be Redeemed. If
less than all 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 

  

 20 

 
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). The Trustee shall make the selection within five Business Days after it receives the notice provided for in Section 3.1 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. 
  
 Securities and portions of Securities that are to be redeemed are convertible by the Holder until the close of business on
the second Business Day prior to the Redemption Date unless the Company fails to pay the Redemption Price on the Redemption Date. If any Security selected for partial redemption is converted in part before termination of the conversion right with
respect to the portion of the Security so selected, the converted portion of such Security shall be deemed (so far as may be) to be the portion selected for redemption. Securities which 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 3.3 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: 
  

	 	(1)	 	the Redemption Date; 

  

	 	(2)	 	the Redemption Price; 

  

	 	(3)	 	the Conversion Price; 

  

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

  

	 	(5)	 	that Securities called for redemption may be converted at any time before the close of business on the second Business Day prior to the Redemption Date; 

  

	 	(6)	 	that Holders who wish to convert their Securities must satisfy the requirements set forth in Section 8 of the Securities; 

  

	 	(7)	 	that Securities called for redemption must be surrendered to the Paying Agent to collect the Redemption Price; 

  

 21 

	 	(8)	 	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;

  

	 	(9)	 	that, unless the Company defaults in making payment of such Redemption Price, interest, including Additional Amounts, if any, on Securities called for redemption will cease to
accrue interest on and after the Redemption Date; and 

  

	 	(10)	 	the CUSIP number(s) of the Securities. 

  
 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 ten Business Days prior to the date by which such notice of redemption is to be given to Holders in accordance with this Section 3.3, unless the Trustee agrees to a shorter period. 
  
 Section 3.4 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. Upon surrender to the
Paying Agent, such Securities shall be paid at the Redemption Price stated in the notice. 
  
 Section 3.5 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 11. 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 3.6 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 3.7 Purchase of Securities at Option of the Holder
upon Change of Control. (a) (1) If a Change of Control occurs (subject to certain exceptions set forth below), the Securities not previously purchased by the Company shall be purchased by the Company for cash, at the option of the Holder
thereof, at a purchase price specified in Section 6 of the Securities (the “Change of Control Purchase Price”), as of the date that is no later than 30 days after the date of a notice of Change of Control delivered by the Company pursuant
to Section 3.7(b) (the “Change of Control Purchase Date”), subject to satisfaction by or on behalf of the Holder of the requirements set forth in Section 3.7(c). 
  

 22 

 A “Change of Control” will be deemed to have occurred at such time after the Securities are
originally issued when any of the following events shall occur: 
  
 (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 purchases, mergers 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 of its subsidiaries or any of its employee benefit plans; or 
  
 (ii) the first day on which a majority of the members of
the board of directors of the Company does not consist of Continuing Directors; or 
  
 (iii) the Company consolidates or merges with or into any other Person, any merger of another Person into the Company, or any conveyance,
transfer, sale, lease or other disposition of all or substantially all of the Company’s properties and assets to another Person, other than: (A) any transaction: (1) that does not result in any reclassification, conversion, exchange or
cancellation of outstanding shares of the Company’s Capital Stock; and (2) pursuant to which the holders of 50% or more of the total voting power of the Company’s Capital Stock entitled to vote generally in elections of directors
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 entitled to vote generally in elections of directors of the continuing or surviving
Person immediately after giving effect to such issuance; and (B) any merger primarily for the purpose of changing the Company’s jurisdiction of incorporation and resulting in a reclassification, conversion or exchange of outstanding shares of
Common Stock, if at all, solely into shares of common stock of the surviving entity. 
  
 A “Continuing Director” shall mean, as of any date of determination, any member of the Board of Directors who: 
  
 (i) was a member of the Board of Directors of the Company on July 10, 2003; or 
  
 (ii) was nominated for election or elected to the Board of
Directors with the approval of a majority of the Continuing Directors who were members of the Board of Directors at the time of the new director’s nomination or election. 
  

	(2)	 	Notwithstanding the provisions of Section 3.7(a)(1), the Company shall not be required to purchase the Securities of the Holders upon a Change of Control pursuant to this Section
3.7 (and a Change of Control shall be deemed not to have occurred) if: 

  

	 	(i)	 	 the Sale Price per share of Common Stock for any five Trading Days within (1) the period of 10 consecutive Trading Days ending immediately after the later of the
Change of Control or the public announcement of the Change of Control, in the case of a Change of Control under clause (i) or 

  

 23 

 (ii) of the definition of “Change of Control” above, or (2) the period of 10 consecutive
Trading Days ending immediately before the Change of Control, in the case of a Change of Control under clause (iii) of the definition of “Change of Control” above, equals or exceeds 110% of the Conversion Price of the Securities in effect
on each of those five Trading Days; or 
  

	 	(ii)	 	all of the consideration 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 Stock Market, and, as a result of the transaction or transactions,
the Securities become convertible solely into that common stock (and any rights attached thereto). 

  
 For the purposes of this Section 3.7, (x) whether a Person is a “beneficial owner” shall be determined in accordance with Rule 13d-3 and Rule 13d-5 under the
Exchange Act (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) 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. 
  
 (b) No later than 30 days after the occurrence of a Change of Control, the Company shall mail a written 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 notice shall include a form of Change of Control Purchase Notice to be completed by the Holder and shall state:

  

	 	(1)	 	briefly, the events causing a Change of Control and the date of such Change of Control; 

  

	 	(2)	 	the date by which the Change of Control Purchase Notice pursuant to this Section 3.7 must be delivered to the Paying Agent in order for a Holder to exercise the repurchase rights;

	 	(7)	 	that the Securities as to which a Change of Control Purchase Notice has been given may be converted if they are otherwise convertible pursuant to Article 10 hereof only if the
Change of Control Purchase Notice has been withdrawn in accordance with the terms of this Indenture; 

  

 24 

	 	(8)	 	that the Securities must be surrendered to the Paying Agent to collect payment; 

  

	 	(9)	 	that the Change of Control Purchase Price for any Security as to which a Change of Control Purchase Notice has been duly given and not withdrawn will be paid promptly following the
later of the Change of Control Purchase Date and the time of surrender of such Security as described in clause (8) above; 

  

	 	(10)	 	briefly, the procedures the Holder must follow to exercise rights under this Section 3.7; 

  

	 	(11)	 	briefly, the conversion rights of the Securities; 

  

	 	(12)	 	the procedures for withdrawing a Change of Control Purchase Notice; 

  

	 	(13)	 	that, unless the Company defaults in making payment of such Change of Control Purchase Price, interest, if any, on Securities surrendered for purchase by the Company will cease to
accrue on and after the Change of Control Purchase Date; and 

  

	 	(14)	 	the CUSIP number(s) of the Securities. 

  
 Without otherwise limiting the Company’s obligations pursuant to this Section 3.7 in any way, the Company shall also issue a press release through
Dow Jones & Company, Inc. or Bloomberg Business News containing the relevant information and otherwise make this information available on the Company’s web site or through another public medium as the Company may use at that time.

  
 (c) A Holder may exercise its rights specified in Section
3.7(a) upon delivery of a written notice of purchase (a “Change of Control Purchase Notice”) to the Paying Agent at any time on or prior to the close of business on the second Business Day preceding the Change of Control Purchase Date
(unless the Company shall specify a later date), specifying: 
  

	 	(1)	 	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;

  

	 	(2)	 	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

  

	 	(3)	 	that such Security shall be purchased pursuant to the terms and conditions specified in Section 6 of the Securities and in this Indenture. 

  
 The delivery of such Security to the Paying Agent with the Change of Control
Purchase 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 Purchase Price 

  

 25 

 
therefor; provided, however, that such Change of Control Purchase Price shall be so paid pursuant to this Section 3.7 and Section 3.8 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 Purchase Notice. 
  
 The Company shall purchase from the Holder thereof, pursuant to this Section 3.7 and Section 3.8, a portion of a Security if the principal amount of such

by Section 3.7(c). Securities in respect of which a Change of Control Purchase Notice has been given by the Holder thereof may not be converted pursuant to Article 9 hereof on or after the date of the delivery of such Change of Control Purchase
Notice unless such Change of Control Purchase Notice has first been validly withdrawn as specified in the following two paragraphs.

Company. 

  
 There shall be no purchase of any
Securities pursuant to Section 3.7 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 Change of Control Purchase Notice) and is continuing an Event of Default (other than
a default in the payment of the Change of Control Purchase Price with respect to such Securities). The Paying Agent will promptly return to the respective Holders thereof any Securities (x) with respect to which a Change of Control Purchase Notice
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 in the payment of the Change of Control Purchase Price with respect to such Securities) in which case, upon
such return, the Change of Control Purchase Notice with respect thereto shall be deemed to have been withdrawn. 
  
 Section 3.9 Deposit of Change of Control Purchase Price. Prior to 10:00 a.m., New York City time, on the Business Day following the Change of
Control Purchase Date, the Company shall deposit with the Trustee or 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
2.4) an amount of cash (in immediately available funds if deposited on such Business Day) sufficient to pay the aggregate Change of Control Purchase Price of all the Securities or portions thereof which are to be purchased as of the Change of

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.  
  
 Section 3.11
Covenant to Comply With Securities Laws Upon Purchase of Securities. When complying with the provisions of Section 3.7 hereof (provided that such offer or purchase constitutes an “issuer tender offer” for purposes of Rule 13e-4
(which term, as used herein, includes any successor provision thereto) under the Exchange Act at the time of such offer or purchase), and subject to any exemptions available under applicable law, the Company shall (i) comply with Rule 13e-4 and Rule
14e-1 (or any successor provision) under the Exchange Act, (ii) file the related Schedule TO (or any successor schedule, form or report) under the Exchange Act, and (iii) otherwise comply with all Federal and state securities laws so as to permit

Company any cash that remains unclaimed as provided in Section 11 of the Securities, together with interest or dividends, if any, thereon (subject to the provisions of Section 7.1(f)), held by them for the payment of the Change of Control Purchase
Price; provided, however, that to the extent that the aggregate amount of cash deposited by the Company pursuant to Section 3.9 exceeds the aggregate Change of Control Purchase Price of the Securities or portions thereof which the Company is
obligated to purchase as of the Change of Control Purchase Date, then, unless otherwise agreed in writing with the Company, promptly after the Business Day following the Change of Control Purchase Date, the Trustee shall return any such excess to
the Company together with interest thereon (subject to the provisions of Section 7.1(f)).

requirements of Section 13 or 15(d) of the Exchange Act, it shall continue to provide the Trustee with reports containing substantially the same information as would have been required to be filed with the SEC had the Company continued to have been
subject to such reporting requirements. In such event, such reports shall be provided at the times the Company would have been required to provide reports had it continued to have been subject to such reporting requirements. The Company also 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 4.3 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 on December 31, 2003) an Officers’ Certificate, stating whether or not to the

 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

 (3) 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 3.1 hereof;

million or more, for a period of 30 days after written notice of default is given to the Company by the Trustee or to the Company and the Trustee by Holders of not less than 25% in aggregate principal amount of the Securities then outstanding, which
default (A) is caused by the failure to pay principal or interest when due on such indebtedness by the end of the applicable grace period, if any, unless such indebtedness is discharged or (B) results in the acceleration of such indebtedness, unless
such acceleration is waived, cured, rescinded or annulled or unless such indebtedness is discharged; 
  
 (7) the entry by a court having jurisdiction in the premises of (i) a decree or order for relief in respect of the Company or any of its Subsidiaries that

Subsidiary, expressly in furtherance of any such action. 
  
 A
Default under clause (5) above is not 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 the
Default and the Company does not cure such Default (and such Default is not waived) within the time specified in clause (5) above after actual receipt of such notice. Any such notice must specify the Default, require that it be remedied and state
that such notice is a “Notice of Default.” 
  
 The
Trustee shall, within 90 days of the occurrence of a Default or Event of Default, give to the Holders of the Securities notice of all uncured Defaults or Events of Default known to it, its status and what action the Company is taking or proposes to
take with respect thereto; provided, however, 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 a Default or
Event of Default under clauses (1), (2), (3) or (4) above. 
  
 Section 6.2 Acceleration. If an Event of Default (other than an Event of Default specified in Section 6.1(7) or (8) with respect to the Company) occurs and is continuing (the Event of Default not having been cured or waived as
provided in this Article 6), 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 plus
accrued and unpaid interest, including Additional Amounts, 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 6.1(7) or (8) occurs (with respect to the Company) and is continuing, the principal amount plus accrued and unpaid interest, including Additional Amounts, 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 

  

 32 

 
judgment or decree and if all existing Events of Default have been cured or waived except nonpayment of the principal amount plus accrued and unpaid
interest, including Additional Amounts, if any, that have become due solely as a result of acceleration and if all amounts due to the Trustee under Section 7.7 have been paid. No such rescission shall affect any subsequent Default or impair any
right consequent thereto. 
  
 Section 6.3 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 plus accrued and unpaid interest, including Additional Amounts, 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 6.4 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 Default and its consequences except (i) an Event of
Default described in Section 6.1(1), 6.1(2), 6.1(3) or 6.1(4), (ii) a Default in respect of a provision that under Section 8.2 cannot be amended without the consent of each Securityholder affected or (iii) a Default which constitutes a failure to
convert any Security in accordance with the terms of Article 9. When a Default is waived, it is deemed cured, but no such waiver shall extend to any subsequent or other Default or impair any consequent right. This Section 6.4 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 6.5 Control by Majority. The Holders of a majority in aggregate principal amount of the Securities at the time outstanding may direct 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 6.5 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 6.6 Limitation on Suits. A Securityholder may not pursue any remedy with respect to this Indenture or the Securities unless:

  

	 	(1)	 	the Holder gives to the Trustee written notice stating that an Event of Default is continuing; 

  

 33 

	 	(2)	 	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;

  

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

  

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

  

	 	(5)	 	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 6.7 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, Redemption Price, Change of Control Purchase Price or interest, including Additional Amounts, if any, in respect of the Securities held by such Holder, on or after the respective due dates expressed in the Securities or any
Redemption Date, and to convert the Securities in accordance with Article 9, 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 6.8 Collection Suit
by Trustee. If an Event of Default described in Section 6.1(1), (2), (3) or (4) 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 7.7. 
  
 Section 6.9 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, Redemption Price, Change of Control Purchase
Price or interest, including Additional Amounts, 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 amount of the principal amount, Redemption Price, Change of Control Purchase Price, or interest, including
Additional Amounts, 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 7.7) and of the Holders allowed in such judicial proceeding, and 

  

 34 

 (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 7.7. 
  
 Nothing herein contained
shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof, or to
authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 
  
 Section 6.10 Priorities. If the Trustee collects any money pursuant to this Article 6, it shall pay out the money in the following order: 
  
 FIRST: to the Trustee for amounts due under Section 7.7; 
  
 SECOND: to Securityholders for amounts due and unpaid on the Securities for the principal amount, Redemption Price, Change
of Control Purchase Price or interest, including Additional Amounts, 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, a suit by a Holder pursuant to Section 6.7 or a suit by Holders of more than 10% in aggregate principal amount of the Securities at the
time outstanding. 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, Redemption Price or Change of Control Purchase Price in respect of Securities, or any 

  

 35 

 
interest, including Additional Amounts, if any, on such amounts, 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 VII 
  
 TRUSTEE 
  
 Section 7.1 Duties of Trustee. (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: 

  

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

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 7.1(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: 
  

	 	(1)	 	this Section (c) does not limit the effect of Section (b) of this Section 7.1;

incur any financial liability unless it receives indemnity satisfactory to it against any loss, liability or expense. 
  
 (f) Money held by the Trustee in trust hereunder need not be segregated from other funds except to the extent required by law. The Trustee (acting in any
capacity hereunder) shall be under no liability for interest on any money received by it hereunder unless otherwise agreed in writing with the Company. 
  
 Section 7.2 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 or other paper or document believed by it to be
genuine and to have been signed or presented by the proper party or parties;

 (f) the
Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request, order or direction of any of the Holders, pursuant to the provisions of this Indenture, unless such Holders shall have

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

 (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 7.3 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. 
  
 Section 7.4 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. 
  

 38 

 Section 7.5 Notice of Defaults. If a Default occurs and if it is known to the Trustee, the Trustee
shall give to each Securityholder notice of the Default within 90 days after it occurs or, if later, within 15 days after it is known to the Trustee, unless such Default shall have been cured or waived before the giving of such notice.
Notwithstanding the preceding sentence, except in the case of a Default described in Section 6.1(1), (2) (3) or (4), 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 unless a Responsible Officer of the Trustee has received written notice of such Default, which notice specifically references this Indenture and the Securities. 
  
 Section 7.6 Reports by Trustee to Holders. Within 60 days after each
May 15 beginning with the May 15 following the date of this Indenture, the Trustee shall mail to each Securityholder a brief report dated as of such May 15 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 7.7
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 expenses, advances and disbursements of its agents and counsel), except any such expense, disbursement or advance as may be attributable to its negligence or bad faith; 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 attorney’s fees and expenses, and taxes (other than taxes based upon, measured by or determined by the income of the Trustee and any and all
franchise taxes of the Trustee)) incurred without negligence or bad faith 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 7.7, the Trustee shall have a lien prior to the Securities
on all money or property held or collected by the Trustee, 

  

 39 

 
except that held in trust to pay the principal amount, Redemption Price, Change of Control Purchase Price or interest, including Additional Amounts, if any,
as the case may be, on particular Securities. 
  
 The
Company’s payment obligations pursuant to this Section 7.7 shall survive the discharge of this Indenture and the resignation or removal of the Trustee. When the Trustee incurs expenses after the occurrence of a Default specified in Section
6.1(6) or (7), the expenses including the reasonable charges and expenses of its counsel, are intended to constitute expenses of administration under any bankruptcy law. 
  
 Section 7.8 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 7.8. 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: 
  
 (1) the Trustee fails to comply with Section 7.10; 
  
 (2) the Trustee is adjudged bankrupt or insolvent; 
  
 (3) a receiver or public officer takes charge of the Trustee or its property; or 
  
 (4) 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. 
  
 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 7.7. 
  
 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. 
  
 Section 7.9 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 

  

 40 

 
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 Commission 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. 
  
 ARTICLE VIII 
  
 AMENDMENTS 
  
 Section 8.1 Without Consent of Holders. The Company and the Trustee may amend, modify or supplement this Indenture or the Securities without the
consent of any Securityholder to: 
  
 (a) add to the covenants of
the Company for the benefit of the Holders of Securities; 
  
 (b)
surrender any right or power herein conferred upon the Company; 
  
 (c) provide for conversion rights of Holders of Securities if any reclassification or change of the Common Stock or any consolidation, merger or sale of all or substantially all of the Company’s assets occurs; 
  
 (d) provide for the assumption of the Company’s obligations to the
Holders of Securities in the case of a merger, consolidation, conveyance, transfer or lease pursuant to Article 5 hereof; 
  
 (e) reduce the Conversion Price; provided, however, that such reduction in the Conversion Price shall not adversely affect the interests of the Holders of
Securities (after taking into account tax and other consequences of such reduction); 
  
 (f) comply with the requirements of the SEC in order to effect or maintain the qualification of this Indenture under the TIA; 
  

(g) cure any ambiguity, to correct or supplement any provision herein which may be inconsistent with any other provision herein or which is otherwise
defective; provided, however, that such action pursuant to this clause (g) does not, in the good faith opinion of the Board of Directors of the Company (as evidenced by a Board Resolution), adversely affect the interests of the Holders of Securities
in any material respect; and 

  

 41 

 (h) add or modify any other provisions herein with respect to matters or questions arising hereunder
which the Company and the Trustee may deem necessary or desirable and that will not, in the good faith opinion of the Board of Directors of the Company (as evidenced by a Board Resolution), adversely affect the interests of the Holders of
Securities. 
  
 Section 8.2 With Consent of Holders. Except
as provided below in this Section 8.2, this Indenture or the Securities may be amended, modified or supplemented, and noncompliance 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 or waiver under this Section 8.2 may not:

  
 (a) change the maturity of the principal amount of, or the
date any installment of interest, including Additional Amounts, is due on, any Security; 
  
 (b) reduce the principal amount of, or interest, including Additional Amounts payable on, or the Redemption Price or Change of Control Purchase Price of, any Security; 
  
 (c) change the currency of any amount owed or owing under the Security or
any interest thereon from U.S. Dollars; 
  
 (d) impair the right
of any Holder to institute suit for the enforcement of any payment or with respect to, or conversion of, any Security; 
  
 (e) modify the obligation of the Company to maintain an office or agency in The City of New York pursuant to Section 4.5; 
  
 (f) except as otherwise permitted or contemplated by the provisions of this
Indenture, adversely affect the repurchase right of the Holders of the Securities as provided in Article 3 or the right of the Holders of the Securities to convert any Security as provided in Article 9; 
  
 (g) modify the provisions of Article 5 in a manner adverse to the Holders of
the Securities; 
  
 (h) modify any of the provisions of this
Section 8.2, or reduce the principal amount of outstanding Securities required to waive a default, except to provide that certain other provisions of this Indenture cannot be modified or waived without the consent of the Holder of each outstanding
Security affected thereby; or 
  
 (i) reduce the percentage of
the principal amount of the outstanding Securities the consent of whose Holders is required for any such supplemental indenture or the consent of whose Holders is required for any waiver provided for in this Indenture. 
  

 42 

 It shall not be necessary for the consent of the Holders under this Section 8.2 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 8.2 becomes effective, the Company shall mail to each Holder a notice briefly describing the amendment. 

 
 Nothing in this Section 8.2 shall impair the ability of the Company and
the Trustee to amend this Indenture or the Securities without the consent of any Securityholder to provide for the assumption of the Company’s obligations to the Holders of Securities in the case of a merger, consolidation, conveyance, transfer
or lease pursuant to Article 5 hereof. 
  
 Section 8.3
Compliance with Trust Indenture Act. Every supplemental indenture executed pursuant to this Article shall comply with the TIA. 
  
 Section 8.4 Revocation and Effect of Consents, Waivers and Actions. Until an amendment, waiver or other action by Holders becomes effective, a
consent thereto by a Holder of a Security hereunder is a continuing consent by the 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 8.5 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 conform, in the opinion of the Trustee and the Board of Directors, to any such supplemental indenture may be prepared and executed by the Company and authenticated and delivered by the Trustee in exchange for outstanding
Securities. 
  
 Section 8.6 Trustee to Sign Supplemental
Indentures. The Trustee shall sign any supplemental indenture authorized pursuant to this Article 8 if the amendment contained therein does not adversely 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 such supplemental indenture the Trustee shall receive, and (subject to the provisions of Section 7.1) shall be fully protected in relying upon, an Officers’ Certificate and
an Opinion of Counsel stating that such amendment is authorized or permitted by this Indenture. 
  
 Section 8.7 Effect of Supplemental Indentures. Upon the execution of any supplemental indenture under this Article, this Indenture shall be
modified in accordance therewith, and such supplemental indenture shall form a part of this Indenture for all purposes; and every Holder of Securities theretofore or thereafter authenticated and delivered hereunder shall be bound thereby.

 ARTICLE IX 
  
 CONVERSIONS 
  
 Section 9.1 Conversion Privilege. (a) Subject to and upon compliance with the provisions of this Article 9, 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 or an integral multiple of $1,000) of such Security into shares of Common Stock at the Conversion Price in effect on the date of conversion,
at any time prior to the close of business on the Business Day prior to the Stated Maturity of the Securities. 
  
 Section 9.2 Conversion Procedure; Conversion Price; Fractional Shares. (a) 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 Security will be converted into shares of Common Stock at the Conversion Price therefor. No payment or adjustment shall be made in respect
of dividends on the Common Stock or accrued interest on a converted Security, except as described in Section 9.9 hereof. 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 9.3(k) hereof, make a cash payment (calculated to the nearest cent) equal to such fraction multiplied by the Sale Price of the Common Stock on the last Trading Day prior to the date of conversion. Notwithstanding the
foregoing, a Security in respect of which a Holder has delivered a Change of Control Purchase Notice exercising such Holder’s option to require the Company to repurchase such Security may be converted only if such notice of exercise is
withdrawn in accordance with the Section 3.8 hereof. 
  
 (b) Before any Holder of a Security shall be entitled to convert the same into Common Stock, such Holder shall, in the case of Global Securities, comply with the procedures of the Depositary in effect at that time, and in the case of
Certificated Securities, surrender such Securities, duly endorsed to the Company or in blank, at the office of the Conversion Agent, and shall give written notice to the Company 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 to be issued. 
  
 Before any such conversion, a Holder also shall pay all funds required, if
any, relating to interest on the Securities, as provided in Section 9.9, and all taxes or duties, if any, as provided in Section 9.8. 
  
 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 which shall be
deliverable upon conversion 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. Subject to the next succeeding sentence, the Company will,
as soon as practicable thereafter, issue and deliver at said office or place to such Holder of a Security, or to such Holder’s nominee or nominees, certificates for the number of full shares of Common Stock to which such Holder shall be
entitled as aforesaid, together with cash in lieu of any fraction of a share to which such Holder would otherwise be entitled. The Company shall not be required to deliver certificates for shares 

  

 44 

 
of Common Stock while the stock transfer books for such stock or the security register are duly closed for any purpose, but certificates for shares of Common
Stock shall be issued and delivered as soon as practicable after the opening of such books or security register. 
  
 (c) A Security shall be deemed to have been converted as of the close of business on the date of the surrender of such Securities for conversion as
provided above, and the Person or Persons entitled to receive the Common Stock issuable upon such conversion shall be treated for all purposes as the record Holder or Holders of such Common Stock as of the close of business on such date. 

 
 (d) 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 9.8 hereof), a new Security or
Securities in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Securities. 
  
 Section 9.3 Adjustment of Conversion Price. The Conversion Price shall be adjusted from time to time as follows: 
  
 (a) In case the Company shall, at any time or from time to time while any of
the Securities are outstanding, pay a dividend or make a distribution in shares of Common Stock to all holders of its outstanding shares of Common Stock, then the Conversion Price in effect at the opening of business on the date following the record
date fixed for the determination of stockholders entitled to receive such dividend or other distribution shall be reduced by multiplying such Conversion Price by a fraction: 
  
 (1) the numerator of which shall be the number of shares of Common Stock outstanding at the close of
business on the Record Date fixed for such determination; and 
  
 (2) 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 reduction shall become effective immediately after the opening of business on the day following the Record Date fixed
for such determination. If any dividend or distribution of the type described in this Section 9.3(a) is declared but not so paid or made, the Conversion Price shall again be adjusted to the Conversion Price which would then be in effect if such
dividend or distribution had not been declared. 
  
 (b) In case
the Company shall, at any time or from time to time while any of the Securities are outstanding, subdivide its outstanding shares of Common Stock into a greater number of shares of Common Stock, then the Conversion Price in effect at the opening of
business on the day following the day upon which such subdivision becomes effective shall be proportionately reduced, and conversely, in case the Company shall, at any time or from time to time while any of the Securities are outstanding, combine
its outstanding shares of Common Stock into a smaller number of shares of Common Stock, then the Conversion Price in effect at the opening of business on the day following the day upon which such combination becomes effective shall be
proportionately increased. 
  

 45 

 Such reduction or increase, as the case may be, shall become effective immediately after the opening of
business on the day following the day upon which such subdivision or combination becomes effective. 
  
 (c) In case the Company shall, at any time or from time to time while any of the Securities are outstanding, issue rights or warrants (other than any
rights or warrants referred to in Section 9.3(d)) to all or substantially all holders of its shares of Common Stock entitling them to subscribe for or purchase shares of Common Stock (or securities convertible into shares of Common Stock) at a price
per share (or having a conversion price per share) less than the Sale Price on the Business Day immediately preceding the date of the announcement of such issuance (treating the conversion price per share of the securities convertible into Common
Stock as equal to (x) the sum of (i) the price for a unit of the security convertible into Common Stock and (ii) any additional consideration initially payable upon the conversion of such security into Common Stock divided by (y) the number of
shares of Common Stock initially underlying such convertible security), then the Conversion Price shall be adjusted so that the same shall equal the price determined by multiplying the Conversion Price in effect at the opening of business on the
date after such date of announcement by a fraction: 
  
 (1) the numerator of which shall be the number of shares of Common Stock outstanding on the close of business on the date of announcement, plus the number of shares or securities which the aggregate offering price of the total number of
shares or securities so offered for subscription or purchase (or the aggregate conversion price of the convertible securities so offered) would purchase at such Sale Price of the Common Stock; and 
  
 (2) the denominator of which shall be the number of shares
of Common Stock outstanding at the close of business on the date of announcement, plus the total number of additional shares of Common Stock so offered for subscription or purchase (or into which the convertible securities so offered are
convertible). 
  
 Such adjustment shall become effective
immediately after the opening of business on the day following the date of announcement of such issuance. To the extent that shares of Common Stock (or securities convertible into shares of Common Stock) are not delivered pursuant to such rights or
warrants, upon the expiration or termination of such rights or warrants, the Conversion Price shall be readjusted to the Conversion Price which would then be in effect had the adjustments made upon the issuance of such rights or warrants been made
on the basis of the delivery of only the number of shares of Common Stock (or securities convertible into shares of Common Stock) actually delivered. In the event that such rights or warrants are not so issued, the Conversion Price shall again be
adjusted to be the Conversion Price which would then be in effect if the date fixed for the determination of stockholders entitled to receive such rights or warrants had not 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 Sale Price, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration received for such rights or
warrants, the value of such consideration if other than cash, to be determined by the Board of Directors. 
  

 46 

 (d) In case the Company shall, at any time or from time to time while any of the Securities are
outstanding, by dividend or otherwise, distribute to all or substantially all holders of its shares of Common Stock (including any such distribution made in connection with a consolidation or merger in which the Company is the continuing corporation
and the Common Stock is not changed or exchanged), cash, shares of its capital stock (other than any dividends or distributions to which Section 9.3(a) applies), evidences of its indebtedness or other assets, including securities, but excluding (i)
any rights or warrants referred to in Section 9.3(c), (ii) dividends or distributions of stock, securities or other property or assets (including cash) in connection with a reclassification, consolidation, merger, statutory share exchange,
combination, sale or conveyance to which Section 9.4 applies and (iii) dividends and distributions paid exclusively in cash (such capital stock, evidence of its indebtedness, cash, other assets or securities being distributed hereinafter in this
Section 9.3(d) called the “distributed assets”), then, in each such case, subject to the third and fourth succeeding paragraphs and the last paragraph of this Section 9.3(d), the Conversion Price shall be reduced so that the same shall be
equal to the price determined by multiplying the Conversion Price in effect immediately prior to the close of business on the Record Date with respect to such distribution by a fraction: 
  
 (1) the numerator of which shall be the Current Market Price of the Common Stock, less the Fair Market Value
on such date of the portion of the distributed assets so distributed applicable to one share of Common Stock (determined on the basis of the number of shares of Common Stock outstanding on the record date)(determined as provided in Section 9.3(g))
on such date; and 
  
 (2) the denominator of
which shall be such Current Market Price. 
  
 Such reduction shall become
effective immediately prior to the opening of business on the day following the Record Date for such distribution. In the event that such dividend or distribution is not so paid or made, the Conversion Price shall again be adjusted to be the
Conversion Price which would then be in effect if such dividend or distribution had not been declared. 
  
 If the Board of Directors determines the Fair Market Value of any distribution for purposes of this Section 9.3(d) by reference to the actual or when
issued trading market for any distributed assets comprising all or part of such distribution, it must in doing so consider the prices in such market over the same period (the “Reference Period”) used in computing the Current Market Price
pursuant to Section 9.3(g) to the extent possible, unless the Board of Directors determines in good faith that determining the Fair Market Value during the Reference Period would not be in the best interest of the Holders. 
  
 In the event any such distribution consists of shares of capital stock of, or
similar equity interests in, one or more of the Company’s Subsidiaries (a “Spin-Off”), the Fair Market Value of the securities to be distributed shall equal the average of the closing sale prices of such securities on the principal
securities market on which such securities are traded for the five consecutive Trading Days commencing on and including the sixth day of trading of those securities after the effectiveness of the Spin-Off, and the Current Market Price shall be
measured for the same period. In the event, however, that an underwritten initial public offering of the securities in the Spin-Off occurs simultaneously with the Spin-Off, Fair Market Value of the securities distributed in the Spin-Off shall mean
the initial public offering price of such securities 

  

 47 

 
and the Current Market Price shall mean the Sale Price for the Common Stock on the same Trading Day. 
  
 Rights or warrants distributed by the Company to all holders of its shares of
Common Stock entitling them 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 shares of Common Stock shall be deemed not to have been distributed for purposes of
this Section 9.3(d) (and no adjustment to the Conversion Price under this Section 9.3(d) will be required) until the occurrence of the earliest Trigger Event. If such right or warrant is subject to subsequent events, upon the occurrence of which
such right or warrant shall become exercisable to purchase different distributed assets, evidences of indebtedness or other assets, or entitle the holder to purchase a different number or amount of the foregoing or to purchase any of the foregoing
at a different purchase price, then the occurrence of each such event shall be deemed to be the date of issuance and record date with respect to a new right or warrant (and a termination or expiration of the existing right or warrant without
exercise by the holder 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 resulted
in an adjustment to the Conversion Price under this Section 9.3(d): 
  
 (1) in the case of any such rights or warrants which shall all have been redeemed or repurchased without exercise by any holders thereof, the Conversion Price 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 of shares of Common Stock with respect to such
rights or warrants (assuming such holder had retained such rights or warrants), made to all holders of shares of Common Stock as of the date of such redemption or repurchase; and 
  
 (2) in the case of such rights or warrants which shall have expired or been terminated without exercise, the
Conversion Price shall be readjusted as if such rights and warrants had never been issued. 
  
 For purposes of this Section 9.3(d) and Sections 9.3(a), 9.3(b) and 9.3(c), any dividend or distribution to which this Section 9.3(d) is applicable that also includes (i) shares of Common Stock, (ii) a subdivision or
combination of shares of Common Stock to which Section 9.3(b) applies or (iii) rights or warrants to subscribe for or purchase shares of Common Stock to which Section 9.3(c) applies (or any combination thereof), shall be deemed instead to be:

  
 (1) a dividend or distribution of the
evidences of indebtedness, assets, shares of capital stock, rights or warrants, other than such shares of Common Stock, such subdivision or combination or such rights or warrants to which Sections 9.3(a), 9.3(b) and 9.3(c) apply, respectively (and
any Conversion Price reduction required by this Section 9.3(d) with respect to such dividend or distribution shall then be made), immediately followed by 

  

 48 

 (2) a dividend or distribution of such shares of Common Stock, such subdivision or
combination or such rights or warrants (and any further Conversion Price reduction required by Sections 9.3(a), 9.3(b) and 9.3(c) 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 (i) “the date fixed for the determination of stockholders entitled to receive such dividend or other distribution,” “Record Date fixed for such determinations” and “Record Date” within the meaning of
Section 9.3(a), (ii) ”the day upon which such subdivision becomes effective” and “the day upon which such combination becomes effective” within the meaning of Section 9.3(b), and (iii) as “the date fixed for the
determination of stockholders entitled to receive such rights or warrants,” “the Record Date fixed for the determination of the stockholders entitled to receive such rights or warrants” and such “Record Date” within the
meaning of Section 9.3(c); 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 9.3(a) and any reduction or increase in the number
of shares of Common Stock resulting from such subdivision or combination shall be disregarded in connection with such dividend or distribution. 
  
 In the event of any distribution referred to in this Section 9.3(d) in which (1) the Fair Market Value (as determined by the Board of Directors) of such
distribution applicable to one share of Common Stock (determined as provided above) equals or exceeds the average of the Sale Prices of the Common Stock over the ten consecutive Trading Day period ending on the Record Date for such distribution or
(2) the average of the Sale Prices of the Common Stock over the ten consecutive Trading Day period ending on the Record Date for such distribution exceeds the Fair Market Value of such distribution by less than $1.00, then, in each such case, in
lieu of an adjustment to the Conversion Price, adequate provision shall be made so that each Holder shall have the right to receive upon conversion of a Security, in addition to shares of Common Stock, the kind and amount of such distribution such
Holder would have received had such Holder converted such Security immediately prior to the Record Date for determining the shareholders entitled to receive the distribution. 
  
 In the event of any distribution referred to in Section 9.3(c) or 9.3(d), where, in the case of a distribution described in
Section 9.3(d), the Fair Market Value of such distribution per share of Common Stock (as determined by the Board of Directors) exceeds 10% of the Sale Price of a share of Common Stock on the Business Day immediately preceding the declaration date
for such distribution, then, if such distribution would also trigger a conversion right under Section 9.1(b) or the Securities are otherwise convertible pursuant to this Article 9, the Company will be required to give notice to the Holders of
Securities at least 20 days prior to the Ex-Dividend Time for the distribution and, upon the giving of notice, 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
conversion right, until the close of business on the Business Day prior to the Ex-Dividend Time or the Company announces that such distribution will not take place. No 

  

 49 

 
adjustment to the Conversion Price or the ability of a Holder of a Security to convert will be made if the Holder will otherwise participate in such
distribution without conversion. 
  
 (e) In case the Company
shall, by dividend or otherwise, distribute to all or substantially all holders of its Common Stock cash (excluding 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 Price shall be reduced so that the same shall equal the rate determined by multiplying the Conversion Price in effect on the applicable record date by a fraction, 
  
 (1) the numerator of which shall be the Current Market Price
on such record date less the full amount of cash so distributed as applicable to one share of Common Stock; and 
  
 (2) the denominator of which shall be the Current Market Price on such record date, 
  
 such adjustment to be effective immediately prior to the opening of business on the day
following the Record Date; provided that if the portion of the cash so distributed applicable to one share of Common Stock is equal to or greater than the Current Market Price 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. If such dividend or distribution is not so
paid or made, the Conversion Price shall again be adjusted to be the Conversion Price that would then be in effect if such dividend or distribution had not been declared. 
  
 (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, whose
determination shall be conclusive and described in a resolution of 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 Closing Sale Price of a share of Common Stock on the Trading Day next succeeding the Expiration Time, the Conversion Price shall be reduced so that the same shall equal the price determined by multiplying the Conversion Price in effect
immediately prior to the Expiration Time by a fraction, 
  
 (1) the numerator of which shall be the number of shares of Common Stock outstanding (including any tendered or exchanged shares) at the Expiration Time multiplied by the Sale Price of a share of 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; and 
  
 (2) the denominator of which shall be the sum of (x) the Fair Market Value (determined as aforesaid) of the
aggregate consideration payable to stockholders based on 

  

 50 

 
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, 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 Sale Price of a share of Common Stock on the Trading Day next succeeding the Expiration Time. 
  
 If 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 Price shall again be adjusted to be the Conversion Price that would then be in effect if such tender or exchange offer had not been made. 
  
 (g) For purposes of this Article 9, the following terms shall have the meanings indicated: 
  
 “Current Market Price” on any date means the average of the daily
Sale Prices per share of Common Stock for the ten consecutive Trading Days immediately prior to such date; provided, however, that if: 
  
 (1) the “ex” date (as hereinafter defined) for any event (other than the issuance or distribution requiring such computation)
that requires an adjustment to the Conversion Price pursuant to Section 9.3(a), (b), (c), (d), (e) or (f) occurs during such ten consecutive Trading Days, the Sale Price for each Trading Day prior to the “ex” date for such other event
shall be adjusted by dividing such Sale Price by the same fraction by which the Conversion Price is so required to be adjusted as a result of such other event; 
  

(2) the “ex” date for any event (other than the issuance or distribution requiring such computation) that requires an
adjustment to the Conversion Price pursuant to Section 9.3(a), (b), (c), (d), (e) or (f) occurs on or after the “ex” date for the issuance or distribution requiring such computation and prior to the day in question, the Sale Price for each
Trading Day on and after the “ex” date for such other event shall be adjusted by dividing such Sale Price by the reciprocal of the fraction by which the Conversion Price is so required to be adjusted as a result of such other event; and

  
 (3) the “ex” date for the issuance
or distribution requiring such computation is prior to the day in question, after taking into account any adjustment required pursuant to clause (1) or (2) of this proviso, the Sale Price for each Trading Day on or after such “ex” date
shall be adjusted by adding thereto the amount of any cash and the Fair Market Value (as determined by the Board of Directors in a manner consistent with any determination of such value for purposes of Section 9.3(d), (e) or (f)) of the evidences of
indebtedness, shares of capital stock or assets being distributed applicable to one share of Common Stock as of the close of business on the day before such “ex” date. 
  
 For purposes of any computation under Section 9.3(f), if the “ex” date for any event (other than the tender offer requiring such
computation) that requires an adjustment to the Conversion Price pursuant to Section 9.3(a), (b), (c), (d), (e) or (f) occurs on or after the Expiration Time for the 

  

 51 

 
tender or exchange offer requiring such computation and prior to the day in question, the Sale Price for each Trading Day on and after the “ex”
date for such other event shall be adjusted by dividing such Sale Price by the reciprocal of the fraction by which the Conversion Price is so required to be adjusted as a result of such other event. For purposes of this paragraph, the term
“ex” date, when used: 
  
 (1) with
respect to any issuance or distribution, means the first date on which the shares of Common Stock trade regular way on the relevant exchange or in the relevant market from which the Sale Price was obtained without the right to receive such issuance
or distribution; 
  
 (2) with respect to any
subdivision or combination of shares of Common Stock, means the first date on which the shares of Common Stock trade regular way on such exchange or in such market after the time at which such subdivision or combination becomes effective; and

  
 (3) with respect to any tender or exchange
offer, means the first date on which the shares of Common Stock trade regular way on such exchange or in such market after the Expiration Time of such offer. 
  
 Notwithstanding the foregoing, whenever successive adjustments to the Conversion Price are called for pursuant to this Section 9.3, such adjustments shall be made to the
Current Market Price as may be necessary or appropriate to effectuate the intent of this Section 9.3 and to avoid unjust or inequitable results as determined in good faith by the Board of Directors. 
  
 “Fair Market Value” shall mean the amount that a willing buyer
would pay a willing seller in an arm’s-length transaction (as determined by the Board of Directors, whose determination shall be conclusive). 
  
 “Record Date” shall mean, with respect to any dividend, distribution or other transaction or event in which the holders of shares of Common
Stock have the right to receive any cash, securities or other property or in which the shares of Common Stock (or other applicable security) is exchanged for or converted into any combination of cash, securities or other property, the date fixed for
determination of stockholders entitled to receive such cash, securities or other property (whether such date is fixed by the Board of Directors or by statute, contract or otherwise). 
  
 (h) The Company shall be entitled to make such additional reductions in the Conversion Price, in addition to those required
by Sections 9.3(a), (b), (c), (d), (e) and (f), as shall be necessary in order that any dividend or distribution of Common Stock, any subdivision, reclassification or combination of shares of Common Stock or any issuance of rights or warrants
referred to above shall not be taxable to the holders of Common Stock for United States Federal income tax purposes. 
  
 (i) To the extent permitted by applicable law, the Company may, from time to time, reduce the Conversion Price by any amount for any period of time, if
such period is at least 20 days and the reduction is irrevocable during the period. Whenever the Conversion Price is reduced pursuant to the preceding sentence, the Company shall mail to the Trustee and each 

  

 52 

 
Holder at the address of such Holder as it appears in the register of the Securities maintained by the Registrar, at least 15 days prior to the date the
reduced Conversion Price takes effect, a notice of the reduction stating the reduced Conversion Price and the period during which it will be in effect. 
  
 (j) In any case in which this Section 9.3 shall require that any adjustment be made effective as of or retroactively immediately following a Record Date,
the Company may elect to defer (but only for five Trading Days following the filing of the statement referred to in Section 9.5) issuing to the Holder of any Securities converted after such Record Date the shares of Common Stock issuable upon such
conversion over and above the shares of Common Stock issuable upon such conversion on the basis of the Conversion Price prior to adjustment; provided, however, that the Company shall deliver to such Holder a due bill or other appropriate instrument
evidencing such Holder’s right to receive such additional shares upon the occurrence of the event requiring such adjustment. 
  
 (k) All calculations under this Section 9.3 shall be made to the nearest cent or one-hundredth of a share, with one-half cent and 0.005 of a share,
respectively, being rounded upward. Notwithstanding any other provision of this Section 9.3, the Company shall not be required to make any adjustment of the Conversion Price unless such adjustment would require an increase or decrease of at least 1%
of such price. Any lesser adjustment shall be carried forward and shall be made at the time of and together with the next subsequent adjustment which, together with any adjustment or adjustments so carried forward, shall amount to an increase or
decrease of at least 1% in such price. Any adjustments under this Section 9.3 shall be made successively whenever an event requiring such an adjustment occurs. 
  

(l) In the event that at any time, as a result of an adjustment made pursuant to this Section 9.3, the Holder of any Securities thereafter surrendered
for conversion shall become entitled to receive any shares of stock of the Company other than shares of Common Stock into which the Securities originally were convertible, the Conversion Price of such other shares so receivable upon conversion of
any such Security shall be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to Common Stock contained in subparagraphs (a) through (k) of this Section 9.3, and the
provision of Sections 9.1, 9.2 and 9.4 through 9.9 with respect to the Common Stock shall apply on like or similar terms to any such other shares and the determination of the Board of Directors as to any such adjustment shall be conclusive.

  
 (m) No adjustment shall be made pursuant to this Section 9.3
(i) if the effect thereof would be to reduce the Conversion Price below the par value (if any) of the Common Stock or (ii) if the Holders of the Securities may participate in the transaction that would otherwise give rise to an adjustment pursuant
to this Section 9.3. 
  
 Section 9.4 Consolidation or Merger of
the Company. If any of the following events occurs, namely: 
  
 (1) any reclassification or change of the outstanding Common Stock (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or
combination); 
  

 53 

 (2) any merger, consolidation, statutory share exchange or combination of the Company
with another corporation as a result of which holders of Common Stock shall be entitled to receive stock, securities or other property or assets (including cash) with respect to or in exchange for such Common Stock; or 
  
 (3) any sale or conveyance of the properties and assets of
the Company as, or substantially as, an entirety to any other corporation as a result of which holders of Common Stock shall be entitled to receive stock, securities or other property or assets (including cash) with respect to or in exchange for
such Common Stock; 
  
 the Company or the successor or purchasing corporation, as
the case may be, shall execute with the Trustee a supplemental indenture (which shall comply with the Trust Indenture Act as in force at the date of execution of such supplemental indenture, if such supplemental indenture is then required to so
comply) providing that such Securities shall be convertible into the kind and amount of shares of stock and other securities or property or assets (including cash) which such Holder would have been entitled to receive upon such reclassification,
change, merger, consolidation, statutory share exchange, combination, sale or conveyance had such Securities been converted into Common Stock immediately prior to such reclassification, change, merger, consolidation, statutory share exchange,
combination, sale or conveyance assuming such holder of Common Stock did not exercise its rights of election, if any, as to the kind or amount of securities, cash or other property receivable upon such merger, consolidation, statutory share
exchange, sale or conveyance (provided, that if the kind or amount of securities, cash or other property receivable upon such merger, consolidation, statutory share exchange, 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 (“Non-Electing Share”), then for the purposes of this Section 9.4, the kind and amount of securities, cash or other property receivable upon such merger, consolidation,
statutory share exchange, sale or conveyance for each Non-Electing Share shall be deemed to be the kind and amount so receivable per share by a plurality of the Non-Electing 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 9. If, in the case of any such reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance, the stock
or other securities and assets receivable thereupon by a holder of Common Stock includes shares of stock or other securities and assets of a corporation other than the successor or purchasing corporation, as the case may be, in such
reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance, then such supplemental indenture shall also be executed by such other corporation and shall contain such additional provisions to protect the
interests of the Holders of the Securities as the Board of Directors shall reasonably consider necessary by reason of the foregoing, including to the extent practicable the provisions providing for the conversion rights set forth in this Article 9.

  
 The Company shall cause notice of the execution of such
supplemental indenture to be mailed to each Holder, at the address of such Holder as it appears on the register of the Securities maintained by the Registrar, within 20 days after execution thereof. Failure to deliver such notice shall not affect
the legality or validity of such supplemental indenture. 
  

 54 

 The above provisions of this Section 9.4 shall similarly apply to successive reclassifications, mergers,
consolidations, statutory share exchanges, combinations, sales and conveyances. 
  
 If this Section 9.4 applies to any event or occurrence, Section 10.3 shall not apply. 
  
 Section 9.5 Notice of Adjustment. Whenever an adjustment in the Conversion Price with respect to the Securities is required: 
  
 (1) the Company shall forthwith place on file with the
Trustee and any Conversion Agent for such securities a certificate of the Treasurer of the Company, stating the adjusted Conversion Price determined as provided herein and setting forth in reasonable detail such facts as shall be necessary to show
the reason for and the manner of computing such adjustment; and 
  
 (2) a notice stating that the Conversion Price has been adjusted and setting forth the adjusted Conversion Price shall forthwith be given by the Company or, at the Company’s request, by the Trustee in the name
and at the expense of the Company, to each Holder in the manner provided in Section 10.2. Any notice so given shall be conclusively presumed to have been duly given, whether or not the Holder receives such notice. 
  
 In addition, whenever an adjustment in the Conversion Price with respect to the Securities is
required, the Company will issue a press release through Dow Jones & Company, Inc. or Bloomberg Business News containing the relevant information and make this information available on the Company’s web site or through another public medium
as it may use at that time. 
  
 Section 9.6 Notice in Certain
Events. In case: 
  
 (1) of a
consolidation or merger to which the Company is a party and for which approval of any stockholders of the Company is required, or of the sale or conveyance to another Person or entity or group of Persons or entities acting in concert as a
partnership, limited partnership, syndicate or other group (within the meaning of Rule 13d-3 under the Exchange Act) of all or substantially all of the property and assets of the Company; or 
  
 (2) of the voluntary or involuntary dissolution, liquidation
or winding up of the Company; or 
  
 (3) of any
action triggering an adjustment of the Conversion Price referred to in clauses (x) or (y) below; 
  
 then, in each case, the Company shall cause to be filed with the Trustee and the Conversion Agent, and shall cause to be given, to the Holders of the Securities in the manner provided in Section 10.2, at least 15 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 any distribution or grant of rights or warrants triggering an adjustment to the Conversion Price pursuant to this
Article 9, or, if a 

  

 55 

 
record is not to be taken, the date as of which the holders of record of Common Stock entitled to such distribution, rights or warrants are to be determined,
or (y) the date on which any reclassification, consolidation, merger, sale, conveyance, dissolution, liquidation or winding up triggering an adjustment to the Conversion Price pursuant to this Article 9 is expected to become effective, 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 sale, conveyance, dissolution,
liquidation or winding up. 
  
 Failure to give such notice or any
defect therein shall not affect the legality or validity of the proceedings described in clause (1), (2) or (3) of this Section 9.6. 
  
 Section 9.7 Company To Reserve Stock: Registration; Listing.  
  
 (a) The Company shall, in accordance with the laws of the State of Washington, at all times reserve and keep available, free
from preemptive rights, out of its authorized but unissued shares of Common Stock, for the purpose of effecting the conversion of the Securities, such number of its duly authorized shares of Common Stock as shall from time to time be sufficient to
effect the conversion of all Securities then outstanding into such Common Stock at any time (assuming that, at the time of the computation of such number of shares or securities, all such Securities would be held by a single Holder); provided,
however, that nothing contained herein shall preclude the Company from satisfying its obligations in respect of the conversion of the Securities by delivery of purchased shares of Common Stock which are then held in the treasury of the Company. The
Company covenants that all shares of Common Stock which may be issued upon conversion of Securities will upon issue be fully paid and nonassessable and free from all liens and charges and, except as provided in Section 9.8, taxes with respect to the
issue thereof. 
  
 (b) If any shares of Common Stock which would
be issuable upon conversion of Securities hereunder require registration with or approval of any governmental authority before such shares or securities may be issued upon such conversion, the Company will in good faith and as expeditiously as
possible endeavor to cause such shares or securities to be duly registered or approved, as the case may be. The Company further covenants that so long as the Common Stock shall be listed on the New York Stock Exchange, the Company will, if permitted
by the rules of such exchange, list and keep listed all Common Stock issuable upon conversion of the Securities, and the Company will endeavor to list the shares of Common Stock required to be delivered upon conversion of the Securities prior to
such delivery upon any other national securities exchange upon which the outstanding Common Stock is listed at the time of such delivery. 
  
 Section 9.8 Taxes on Conversion. The issue of stock certificates on conversion of Securities shall be made without charge to the converting Holder
for any documentary, stamp or similar issue or transfer taxes in respect of the issue thereof, and the Company shall pay any and all documentary, stamp or similar issue or transfer taxes that may be payable in respect of the issue or delivery of
shares of Common Stock on conversion of Securities pursuant hereto. The Company shall not, however, be required to pay any such tax which may be payable in respect of any transfer involved in the issue or delivery of shares of Common Stock or the
portion, if any, of the Securities which are not so converted in a name other than that in which 

  

 56 

 
the Securities so converted were registered, and no such issue or delivery shall be made unless and until the Person requesting such issue has paid to the
Company the amount of such tax or has established to the satisfaction of the Company that such tax has been paid. 
  
 Section 9.9 Conversion After Record Date. Except as provided below, if any Securities are surrendered for conversion on any day other than an
Interest Payment Date, the Holder of such Securities shall not be entitled to receive any interest that has accrued on such Securities since the prior Interest Payment Date. By delivery to the Holder of the number of shares of Common Stock or other
consideration issuable upon conversion in accordance with this Article 9, any accrued and unpaid interest on such Securities will be deemed to have been paid in full. 
  
 If any Securities are surrendered for conversion subsequent to the Record Date preceding an Interest Payment Date but on or
prior to such Interest Payment Date, the Holder of such Securities at the close of business on such Record Date shall receive the interest payable on such Securities on such Interest Payment Date notwithstanding the conversion thereof. Securities
surrendered for conversion during the period from the close of business on any Record Date preceding any Interest Payment Date to the opening of business on such Interest Payment Date shall (except in the case of Securities which have been called
for redemption on a Redemption Date between such Record Date and the third Business Day after such Interest Payment Date) be accompanied by payment by Holders, for the account of the Company, in New York Clearing House funds or other funds of an
amount equal to the interest payable on such Interest Payment Date on the Securities being surrendered for conversion. Except as provided in this Section 9.9, no adjustments in respect of payments of interest on Securities surrendered for conversion
or any dividends or distributions or interest on the Common Stock issued upon conversion shall be made upon the conversion of any Securities. 
  
 Section 9.10 Company Determination Final. Any determination that the Company or the Board of Directors must make pursuant to this Article 9 shall
be conclusive if made in good faith and in accordance with the provisions of this Article, absent manifest error, and set forth in a Board Resolution.  
  

Section 9.11 Responsibility of Trustee for Conversion Provisions. The Trustee has no duty to determine when an adjustment under this Article 9
should be made, how it should be made or what it should be. The Trustee makes no representation as to the validity or value of any securities or assets issued upon conversion of Securities. The Trustee shall not be responsible for any failure of the
Company to comply with this Article 9. Each Conversion Agent other than the Company shall have the same protection under this Section 9.11 as the Trustee.  
  
 The rights, privileges, protections, immunities and benefits given to the Trustee under the Indenture including, without
limitation, its rights to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each Paying Agent or Conversion Agent acting hereunder. 
  
 Section 9.12 Unconditional Right of Holders to Convert.
Notwithstanding any other provision in this Indenture, the Holder of any Security shall have the right, which is 

  

 57 

 
absolute and unconditional, to convert its Security in accordance with this Article 9 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] 
  
 6.25% Convertible Senior Notes due 2008 
  
 This Security is one of a duly authorized issue of the 6.25% Convertible Senior Notes due 2008 (the “Securities”)
of Indevus Pharmaceuticals, Inc., a Delaware corporation (including any successor corporation under the Indenture hereinafter referred to, the “Company”), issued under an Indenture, dated as of July 16, 2003 (the “Indenture”),
between the Company and The Bank of New York, 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 Company promises to pay Interest on the principal amount
of the Securities at the interest rate of 6.25% (the “Interest Rate”) from the date of issuance until repayment in full at July 15, 2008, or until an earlier conversion, redemption or repurchase. The Company will pay Interest on this
Security semi-annually in arrears on January 15 and July 15 of each year (each, an “interest payment date”), commencing January 15, 2004. 
  
 The Securities shall bear interest from July 16, 2003 until the principal amount thereof is paid or made available for payment, or until such date on
which the Securities are converted, redeemed or purchased as provided herein at a rate of 6.25% per annum. 
  
 Interest on the Securities shall be computed (i) for any full semi-annual period for which a particular Interest Rate is applicable, on the basis of a
360-day year of twelve 30-day months and (ii) for any period for which a particular Interest Rate is applicable for less than a full semiannual period for which Interest is calculated, on the basis of a 30-day month and, for such periods of less
than a month, the actual number of days elapsed over a 30-day month. 
  
 If this Security is redeemed or repurchased by the Company on a date that is after the record date and prior to the corresponding interest payment date, interest and Additional Amounts, if any, accrued and unpaid hereon to but not including
the applicable Redemption Date or Change of Control Purchase Date, as the case may be, will be paid to the same Holder to whom the Company pays the principal of this Security. 
  
 Interest on Securities converted after a record date but prior to the corresponding interest payment date will be paid to
the Holder of the Securities on the record date but, upon conversion, the Holder must pay the Company the interest and Additional Amounts, if any, which have accrued and will be paid on such interest payment date; provided, that no such

  

 A-4 

 
payment need be made with respect to Securities which will be redeemed by the Company after a record date and prior to the third Business Day after the
corresponding interest payment date. 
  
 If the principal amount
hereof or any portion of such principal amount or any interest, including Additional Amounts, if any, on any Security is not paid when due (whether upon acceleration pursuant to Section 6.2 of the Indenture, upon the date set for payment of the
Redemption Price pursuant to Section 5 hereof or the Change of Control Purchase Price pursuant to Section 6 hereof or upon the Stated Maturity of this Security), then in each such case the overdue amount shall, to the extent permitted by law, bear
interest at the Interest Rate, compounded semi-annually, which interest shall accrue from the date on which such overdue amount was originally due to the date of payment of such amount, including interest thereon, has been made or duly provided for.
All such interest shall be payable on demand. 
  
 2. Method of Payment. 
  
 Except as provided
below, interest will be paid (i) on the Global Securities to The Depository Trust Company (“DTC”) or its nominee in immediately available funds, (ii) on any definitive Securities having an aggregate principal amount of $5,000,000 or less,
by check mailed to the Holders of such Securities; and (iii) on any definitive Securities having an aggregate principal amount of more than $5,000,000, by wire transfer in immediately available funds at the election of the Holders of such
Securities. 
  
 At Stated Maturity the Company will pay interest
on definitive Securities at the Company’s office or agency in New York City, which initially will be the Corporate Trust Office of the Trustee in New York City. 
  
 Principal on Global Securities will be paid to DTC or its nominee in immediately available funds. Principal on definitive

 4. Indenture. 
  
 The Securities are senior unsecured obligations of the Company limited to $60,000,000 aggregate principal amount (up to
$72,000,000 aggregate principal amount if the Initial Purchasers exercise their option to purchase up to $12,000,000 aggregate principal amount of additional Securities). The Indenture does not limit other indebtedness of the Company, secured or
unsecured. 
  
 5. Redemption at the Option of
the Company. 
  
 No sinking fund is provided for the
Securities. The Securities are not redeemable by the Company prior to July 20, 2006. 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, 2006 upon not less
than 30 nor more than 60 days’ notice (the “Redemption Notice”) by mail for a redemption price equal to the principal amount of those Securities plus accrued and unpaid interest, including Additional Amounts, if any, up to the
Redemption Date (the “Redemption Price”); provided, that the Current Market Value for the Common Stock equals or exceeds 150% of the Conversion Price in then in effect for at least 20 Trading Days in any consecutive 30 Trading Day period
ending on the Trading Day prior to the date of the mailing of the Redemption Notice by the Company. The term “Current Market Value”, for any Trading Day, shall mean the Sale Price of the Common Stock, as reported on the Nasdaq Stock Market
or the principal national securities exchange or inter-dealer quotation system on which the Common Stock is then listed, on such Trading Day. 
  
 6. Purchase By the Company at the Option of the Holder. 
  
 At the option of the Holder and subject to the terms and conditions of the Indenture, the Company shall become obligated to
offer to purchase the Securities held by such Holder within 30 days after the occurrence of a Change of Control of the Company for a Change of Control Purchase Price equal to the principal amount plus accrued and unpaid interest, including
Additional Amounts, if any, of such Security on the Change of Control Purchase Date. The Change of Control Purchase Date shall be within 30 days of the Company’s delivery of the notice described in the preceding sentence. The Change of Control
Purchase Price shall be paid in cash. 
  
 Holders have the right
to withdraw any Change of Control Purchase 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 Change of Control Purchase Price of all Securities or portions thereof to be purchased as of
the Change of Control Purchase Date, is deposited with the Paying Agent, on the Business Day following the Change of Control Purchase Date, interest will cease to accrue on such Securities (or portions thereof) immediately after such Change of
Control Purchase Date, and the Holder thereof shall have no other rights as such other than the right to receive the Change of Control Purchase Price upon surrender of such Security. 
  
 7. Notice of Redemption. 
  

 A-6 

 Notice of redemption pursuant to Section 5 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, immediately after such Redemption Date interest ceases to accrue on such Securities or portions thereof. Securities in denominations larger than $1,000 of principal amount
may be redeemed in part but only in integral multiples of $1,000 of principal amount. 
  
 8. Conversion. 
  
 Subject to and in compliance with the provisions of the Indenture, 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 Price in effect at the time of conversion. 
  
 A Security in respect of which a Holder has delivered a Change of Control
Purchase Notice, exercising the option of such Holder to require the Company to purchase such Security, may be converted only if such Change of Control Purchase Notice is withdrawn in accordance with the terms of the Indenture. 
  
 The initial Conversion Price is $6.656, subject to adjustment in certain
events described in the Indenture. A Holder that surrenders Securities for conversion will receive cash or a check in lieu of any fractional share of Common Stock. 
  
 To surrender a Security for conversion, a Holder must (1) complete and manually sign the conversion notice below (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 and (4) pay any transfer or
similar tax, if required by the Indenture. 
  
 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 or binding share exchange, (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. 
  
 9. 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 

  

 A-7 

 
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 Purchase 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. 
  
 10. Persons Deemed Owners. 
  
 The registered Holder of this Security may be treated as the owner of this Security for all purposes. 
  
 11. Unclaimed Money or Securities. 
  
 The Trustee and the Paying Agent shall return to the Company upon written
request any money 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. 
  
 12. 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 Defaults may be waived with the written consent of the Holders of a majority in aggregate principal amount of the outstanding Securities. The Indenture and
the Securities may also be amended by the Company and the Trustee, without the consent of any Holder, in certain circumstances set forth in the Indenture; provided, that certain provisions of the Indenture and the Securities may not be amended
without the consent of each affected Holder. 
  
 13. Defaults and Remedies. 
  
 If any Event of
Default with respect to Securities shall occur and be continuing, the principal of all the Securities may be declared due and payable in the manner and with the effect provided in the Indenture. 
  
 14. 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. 
  

 A-8 

 15. No Recourse Against Others. 
  
 A director, officer, employee or shareholder, as such, of the Company shall
not have any liability for any obligations of the Company under the Securities or the Indenture 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. 
  
 16. Authentication. 
  
 This Security shall not be valid until an authorized signatory of the Trustee manually signs the Trustee’s Certificate of Authentication on the other
side of this Security.

the proposed distribution by such Holder of its Transfer Restricted Securities, in connection with the Shelf Registration Statement or Prospectus or Preliminary Prospectus included therein and in any application to be filed with or under state
securities law, as the Company may reasonably request. In connection with all such requests for information from Holders of Transfer Restricted Securities, the Company shall notify such Holders of the requirements set forth in this paragraph
regarding their obligation to provide the information requested pursuant to this Section. Holders who have not delivered a Questionnaire prior to the effectiveness of the Shelf Registration Statement may receive a Questionnaire from the Company upon
request. Upon receipt of such a completed Questionnaire from a Holder following the effectiveness of the Shelf Registration Statement, the Company shall, as promptly as reasonably practicable, file such amendments to the Shelf Registration Statement
or supplements to a related Prospectus as are necessary to permit such Holder to transfer its Transfer Restricted Securities pursuant to the Shelf Registration Statement. Each Holder as to which the Shelf Registration Statement is being effected
agrees to furnish promptly to the Company all information required to be disclosed in order to make information previously furnished to the Company by such Holder not materially misleading. 
  
 3. Additional Amounts. 
  
 (a) If: 
  
 (i) the Shelf Registration Statement is not filed with the Commission prior to or on the Shelf Filing
Deadline; 
  
 (ii) the Shelf Registration
Statement has not been declared effective by the Commission prior to or on the Effectiveness Target Date; 
  
 (iii) except as provided in Section 4(b)(i) hereof, the Shelf Registration Statement is filed and declared effective but, during the
Effectiveness Period, shall thereafter cease to be effective or fail to be usable for its intended purpose without being succeeded within two Business Days by a post-effective amendment to the Shelf Registration Statement, a supplement to the
Prospectus or a report filed with the Commission pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act that cures such failure and, in the case of a post-effective amendment, is itself immediately declared effective; or 
  
 (iv) (A) prior to or on the 60th or 90th day, as the case may be, of any Suspension Period, such suspension has not been terminated or (B) Suspension Periods exceed an aggregate of 120 days in any 360 day period, 
  
 (each such event referred to in foregoing clauses (i) through (iv), a “Registration
Default”), the Company hereby agrees to pay additional amounts (“Additional Amounts”) with respect to the Transfer Restricted Securities from and including the day following the Registration Default to but excluding the day
on which the Registration Default has been cured, accruing at a rate: 
  
 (A) in respect of the Notes, to each holder of Notes, (x) with respect to the first 90-day period during which a Registration Default shall have occurred 
  

 5 

 
and be continuing, equal to 0.25% per annum of the principal amount of the Notes, and (y) with respect to the period commencing on the 91st day following the day the Registration Default shall have occurred and be continuing, equal to 0.50% per annum of the
principal amount of the Notes; provided that in no event shall Additional Amounts accrue at a rate per year exceeding 0.50% of the Applicable Amount of the Notes; and 
  
 (B) in respect of any shares of Common Stock, to each holder of shares of Common Stock issued upon
conversion of Notes, (x) with respect to the first 90-day period in which a Registration Default shall have occurred and be continuing, equal to 0.25% per annum of the Applicable Amount of the converted Notes, and (y) with respect to the period
commencing the 91st day following the day the Registration Default shall have occurred and be continuing, equal to
0.50% per annum of the Applicable Amount of the converted Notes; provided that in no event shall Additional Amounts accrue at a rate per year exceeding 0.50% of the Applicable Amount of the converted Notes. 
  
 (b) All accrued Additional Amounts shall be paid in arrears to Record Holders
by the Company on each Additional Amounts Payment Date by wire transfer of immediately available funds or by federal funds check. Following the cure of all Registration Defaults relating to any particular Security or share of Common Stock, the
accrual of Additional Amounts with respect to such Security or share of Common Stock will cease. The Company agrees to deliver all notices, certificates and other documents contemplated by the Indenture in connection with the payment of Additional
Amounts. 
  
 All obligations of the Company set forth in this
Section 3 that are outstanding with respect to any Transfer Restricted Security at the time such security ceases to be a Transfer Restricted Security shall survive until such time as all such obligations with respect to such Transfer Restricted
Security shall have been satisfied in full. 
  
 The Additional
Amounts set forth above shall be the exclusive monetary remedy available to the Holders of Transfer Restricted Securities for such Registration Default. 
  
 4. Registration Procedures. 
  
 (a) In connection with the Shelf Registration Statement, the Company shall comply with all the provisions of Section 4(b) hereof and shall use its
reasonable best efforts to effect such registration to permit the sale of the Transfer Restricted Securities being sold in accordance with the intended method or methods of distribution thereof, and pursuant thereto, shall prepare and file with the
Commission a Shelf Registration Statement relating to the registration on any appropriate form under the Securities Act. 
  
 (b) In connection with the Shelf Registration Statement and any Prospectus required by this Agreement to permit the sale or resale of Transfer Restricted
Securities, the Company shall: 
  
 (i) Use its
reasonable best efforts to keep the Shelf Registration Statement continuously effective during the Effectiveness Period; upon the 

  

 6 

 
occurrence of any event or the existence of any fact that would cause the Shelf Registration Statement or the Prospectus contained therein, in either case
including any document incorporated by reference therein, (A) to contain a material misstatement or omission or (B) not be effective and usable for resale of Transfer Restricted Securities during the Effectiveness Period, the Company shall file
promptly an appropriate amendment to the Shelf Registration Statement, a supplement to the Prospectus or a report filed with the Commission pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act, in the case of clause (A), correcting any
such misstatement or omission, and, in the case of either clause (A) or (B), use its reasonable best efforts to cause such amendment to be declared effective and the Shelf Registration Statement and the related Prospectus to become usable for their
intended purposes as soon as practicable thereafter. Notwithstanding the foregoing, the Company may suspend the effectiveness of the Shelf Registration Statement by written notice to the Holders for a period not to exceed an aggregate of 60 days in
any 90-day period (each such period, a “Suspension Period”) if: 
  
 (x) an event occurs and is continuing as a result of which the Shelf Registration Statement would, in the Company’s reasonable
judgment, contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading; and 
  
 (y) the Company reasonably determines that the disclosure of such event at such time would have a material
adverse effect on the business of the Company (and its subsidiaries, if any, taken as a whole); 
  
 provided that in the event the disclosure relates to a previously undisclosed proposed or pending material business transaction, the disclosure of
which would impede the Company’s ability to consummate such transaction, the Company may extend a Suspension Period from 60 days to 90 days; provided, however, that Suspension Periods shall not exceed an aggregate of 120 days in any
360-day period. 
  
 (ii) Prepare and file with
the Commission such amendments and post-effective amendments to the Shelf Registration Statement as may be necessary to keep the Shelf Registration Statement effective during the Effectiveness Period; cause the Prospectus to be supplemented by any
required Prospectus supplement, and as so supplemented to be filed pursuant to Rule 424 under the Securities Act, and to comply fully with the applicable provisions of Rules 424 and 430A under the Securities Act in a timely manner; and comply with
the provisions of the Securities Act with respect to the disposition of all securities covered by the Shelf Registration Statement during the applicable period in accordance with the intended method or methods of distribution by the sellers thereof
set forth in the Shelf Registration Statement or supplement to the Prospectus. 
  

 7 

 (iii) Advise the underwriter(s), if any, and selling Holders promptly (but in any event
within two Business Days) and, if requested by such Persons, to confirm such advice in writing: 
  
 (A) when the Prospectus or any Prospectus supplement or post-effective amendment has been filed, and, with respect to the Shelf
Registration Statement or any post-effective amendment thereto, when the same has become effective, 
  
 (B) of any request by the Commission for amendments to the Shelf Registration Statement or amendments or supplements to the Prospectus or
for additional information relating thereto, 
  
 (C) of the issuance by the Commission of any stop order suspending the effectiveness of the Shelf Registration Statement under the Securities Act or of the suspension by any state securities commission of the qualification of the Transfer
Restricted Securities for offering or sale in any jurisdiction, or the initiation of any proceeding for any of the preceding purposes, or 
  
 (D) of the existence of any fact or the happening of any event, during the Effectiveness Period, that makes any statement of a material
fact made in the Shelf Registration Statement, the Prospectus, any amendment or supplement thereto, or any document incorporated by reference therein untrue, or that requires the making of any additions to or changes in the Shelf Registration
Statement or the Prospectus in order to make the statements therein not misleading. 
  
 If at any time the Commission shall issue any stop order suspending the effectiveness of the Shelf Registration Statement, or any state securities commission or other regulatory authority shall issue an order
suspending the qualification or exemption from qualification of the Transfer Restricted Securities under state securities or Blue Sky laws, the Company shall use its reasonable best efforts to obtain the withdrawal or lifting of such order at the
earliest possible time and will provide to the Initial Purchasers and each Holder who is named in the Shelf Registration Statement prompt notice of the withdrawal of any such order. 
  
 (iv) Furnish to each of the selling Holders and each of the underwriter(s), if any, before filing with the
Commission, a copy of the Shelf Registration Statement and copies of any Prospectus included therein or any amendments or supplements to the Shelf Registration Statement or Prospectus (other than documents incorporated by reference after the initial
filing of the Shelf Registration Statement), which documents will be subject to the review of such holders and underwriter(s), if any, for a period of at least ten Business Days (in the case of the Shelf Registration Statement and Prospectus) and
two Business Days (in the case of any amendment or supplement thereto), and the Company 

  

 8 

 
will not file the Shelf Registration Statement or Prospectus or any amendment or supplement to the Shelf Registration Statement or Prospectus (other than
documents incorporated by reference) to which a selling Holder of Transfer Restricted Securities covered by the Shelf Registration Statement or the underwriter(s), if any, shall reasonably object prior to the filing thereof. A selling Holder or
underwriter, if any, shall be deemed to have reasonably objected to such filing if the Shelf Registration Statement, amendment, Prospectus or supplement, as applicable, as proposed to be filed, contains a material misstatement or omission.

  
 (v) Make available at reasonable times for
inspection by one or more representatives of the selling Holders, designated in writing by a Majority of Holders whose Transfer Restricted Securities are included in the Shelf Registration Statement, any underwriter participating in any distribution
pursuant to the Shelf Registration Statement, and any attorney or accountant retained by such selling Holders or any of the underwriter(s), all financial and other records, pertinent corporate documents and properties of the Company as shall be
reasonably necessary to enable them to exercise any applicable due diligence responsibilities, and cause the Company’s officers, directors, managers and employees to supply all information reasonably requested by any such representative or
representatives of the selling Holders, underwriter, attorney or accountant in connection with the Shelf Registration Statement after the filing thereof and before its effectiveness, provided, however, that any information designated by the
Company as confidential at the time of delivery of such information shall be kept confidential by the recipient thereof. 
  
 (vi) If requested by any selling Holders or the underwriter(s), if any, promptly incorporate in the Shelf Registration Statement or
Prospectus, pursuant to a supplement or post-effective amendment if necessary, such information as such selling Holders and underwriter(s), if any, may reasonably request to have included therein, including, without limitation: (1) information
relating to the “Plan of Distribution” of the Transfer Restricted Securities, (2) information with respect to the principal amount of Notes or number of shares of Common Stock being sold to such underwriter(s), (3) the purchase price being
paid therefor and (4) any other terms of the offering of the Transfer Restricted Securities to be sold in such offering; and make all required filings of such Prospectus supplement or post-effective amendment as soon as reasonably practicable after
the Company is notified of the matters to be incorporated in such Prospectus supplement or post-effective amendment. 
  
 (vii) Furnish to each selling Holder and each of the underwriter(s), if any, without charge, at least one copy of the Shelf Registration
Statement, as first filed with the Commission, and of each amendment thereto (and any documents incorporated by reference therein or exhibits thereto (or exhibits incorporated in such exhibits by reference) as such Person may request). 

 

 9 

 (viii) Deliver to each selling Holder and each of the underwriter(s), if any, without
charge, as many copies of the Prospectus (including each preliminary prospectus) and any amendment or supplement thereto as such Persons reasonably may request; subject to any notice by the Company in accordance with this Section 4(b) of the
existence of any fact or event of the kind described in Section 4(b)(iii)(D), the Company hereby consents to the use of the Prospectus and any amendment or supplement thereto by each of the selling Holders and each of the underwriter(s), if any, in
connection with the offering and the sale of the Transfer Restricted Securities covered by the Prospectus or any amendment or supplement thereto. 
  
 (ix) The Company shall: 
  
 (A) upon request, furnish to each selling Holder and each underwriter, if any, in such substance and scope as they may reasonably request
and as are customarily made by issuers to underwriters in primary underwritten offerings for selling security holders, upon the date of closing of any sale of Transfer Restricted Securities in an Underwritten Registration: 
  
 (1) a certificate, dated the date of such closing, signed
by the Chief Financial Officer of the Company confirming, as of the date thereof, matters of the type set forth in Section 5(f) of the Purchase Agreement and such other matters as such parties may reasonably request; 
  
 (2) opinions, each dated the date of such closing, of
counsel to the Company covering such of the matters as are customarily covered in legal opinions to underwriters in connection with underwritten offerings of securities; and 
  
 (3) customary comfort letters, dated the date of such closing, from the Company’s independent
accountants in the customary form and covering matters of the type customarily covered in comfort letters to underwriters in connection with underwritten offerings of securities; 
  
 (B) set forth in full in the underwriting agreement, if any, indemnification provisions and procedures which
provide rights no less protective than those set forth in Section 6 hereof with respect to all parties to be indemnified; and 
  
 (C) deliver such other documents and certificates as may be reasonably requested by such parties to evidence compliance with clause (A)
above and with any customary conditions contained in the underwriting agreement or other agreement entered into by the selling Holders pursuant to this clause (ix). 
  
 (x) Before any public offering of Transfer Restricted Securities, cooperate with the selling Holders, the
underwriter(s), if any, and their respective counsel in connection with the registration and qualification of the Transfer Restricted Securities under the securities or Blue Sky laws of such jurisdictions in 

  

 10 

 
the United States as the selling Holders or underwriter(s), if any, may reasonably request and do any and all other acts or things necessary or advisable to
enable the disposition in such jurisdictions of the Transfer Restricted Securities covered by the Shelf Registration Statement; provided, however, that the Company shall not be required (A) to register or qualify as a foreign corporation or a
dealer of securities where it is not now so qualified or to take any action that would subject it to the service of process in any jurisdiction where it is not now so subject or (B) to subject itself to taxation in any such jurisdiction if it is not
now so subject. 
  
 (xi) Cooperate with the
selling Holders and the underwriter(s), if any, to facilitate the timely preparation and delivery of certificates representing Transfer Restricted Securities to be sold and not bearing any restrictive legends (unless required by applicable
securities laws); and enable such Transfer Restricted Securities to be in such denominations and registered in such names as the Holders or the underwriter(s), if any, may request at least two Business Days before any sale of Transfer Restricted
Securities made by such underwriter(s). 
  
 (xii)
Use its reasonable best efforts to cause the Transfer Restricted Securities covered by the Shelf Registration Statement to be registered with or approved by such other U.S. governmental agencies or authorities as may be necessary to enable the
seller or sellers thereof or the underwriter(s), if any, to consummate the disposition of such Transfer Restricted Securities. 
  
 (xiii) Provide CUSIP numbers for all Transfer Restricted Securities not later than the effective date of the Shelf Registration Statement
and provide the Trustee under the Indenture with certificates for the Notes that are in a form eligible for deposit with The Depository Trust Company. 
  
 (xiv) Cooperate and assist in any filings required to be made with the NASD and in the performance of any due diligence investigation by
any underwriter that is required to be retained in accordance with the rules and regulations of the NASD. 
  
 (xv) Otherwise use its reasonable best efforts to comply with all applicable rules and regulations of the Commission and all reporting
requirements under the Exchange Act. 
  
 (xvi)
Cause the Indenture to be qualified under the TIA not later than the effective date of the Shelf Registration Statement required by this Agreement, and, in connection therewith, cooperate with the Trustee and the holders of Notes to effect such
changes to the Indenture as may be required for such Indenture to be so qualified in accordance with the terms of the TIA; and execute and use its reasonable best efforts to cause the Trustee thereunder to execute all documents that may be required
to effect such changes and all other forms and documents required to be filed with the Commission to enable such Indenture to be so qualified in a timely manner. 
  

 11 

 (xvii) Cause all shares of Common Stock covered by the Shelf Registration Statement to be
listed or quoted, as the case may be, on each securities exchange or automated quotation system on which similar securities issued by the Company are then listed or quoted. 
  
 (xviii) Provide to each Holder upon written request each document filed with the Commission pursuant to the
requirements of Section 13 and Section 15 of the Exchange Act after the effective date of the Shelf Registration Statement. 
  
 (xix) If requested by the underwriter(s), make appropriate officers of the Company available to the underwriter(s) for meetings with
prospective purchasers of the Transfer Restricted Securities and prepare and present to potential investors customary “road show” or marketing materials in a manner consistent with other new issuances of other securities similar to the
Transfer Restricted Securities. 
  
 (c) Each Holder agrees by
acquisition of a Transfer Restricted Security that, upon receipt of any notice from the Company of the existence of any fact of the kind described in Section 4(b)(iii)(D) hereof, such Holder will, and will use its reasonable best efforts to cause
any underwriter(s) in an Underwritten Offering to, forthwith discontinue disposition of Transfer Restricted Securities pursuant to the Shelf Registration Statement until: 
  
 (i) such Holder has received copies of the supplemented or amended Prospectus contemplated by Section
4(b)(i) and 4(b)(viii) hereof; or 
  
 (ii) such
Holder is advised in writing by the Company that the use of the Prospectus may be resumed, and has received copies of any additional or supplemental filings that are incorporated by reference in the Prospectus. 
  
 If so directed by the Company, each Holder will deliver to the Company (at the Company’s
expense) all copies, other than permanent file copies then in such Holder’s possession, of the Prospectus covering such Transfer Restricted Securities that was current at the time of receipt of such notice of suspension. 
  
 5. Registration Expenses. All expenses incident to the
Company’s performance of or compliance with this Agreement shall be borne by the Company regardless of whether a Shelf Registration Statement becomes effective, including, without limitation: 
  
 (i) all registration and filing fees and expenses (including
filings made by any Initial Purchasers or Holders with the NASD); 
  
 (ii) all fees and expenses of compliance with federal securities and state Blue Sky or securities laws; 
  
 (iii) all expenses of printing (including printing of Prospectuses and certificates for the Common Stock to be issued upon conversion of
the Notes) and the Company’s expenses for messenger and delivery services and telephone; 
  

 12 

 (iv) all fees and disbursements of counsel to the Company and, subject to Section 5(b)
below, the Holders of Transfer Restricted Securities; 
  
 (v) all application and filing fees in connection with listing (or authorizing for quotation) the Common Stock on a national securities exchange or automated quotation system pursuant to the requirements hereof; and 
  
 (vi) all fees and disbursements of independent certified
public accountants of the Company (including the expenses of any special audit and comfort letters required by or incident to such performance). 
  
 The Company shall bear its internal expenses (including, without limitation, all salaries and expenses of its officers and employees performing legal,
accounting or other duties), the expenses of any annual audit and the fees and expenses of any Person, including special experts, retained by the Company. 
  
 (b) In connection with the Shelf Registration Statement required by this Agreement, including any amendment or supplement thereto, and any other documents
delivered to any Holders, the Company shall reimburse the Initial Purchasers and the Holders of Transfer Restricted Securities being registered pursuant to the Shelf Registration Statement, as applicable, for the reasonable fees and disbursements of
not more than one counsel, which shall be chosen by a Majority of Holders for whose benefit the Shelf Registration Statement is being prepared. 
  
 6. Indemnification and Contribution. 
  
 (a) The Company shall indemnify and hold harmless each Holder, such Holder’s officers, directors, partners and employees and each person, if any, who
controls such Holder within the meaning of the Securities Act (each, an “Indemnified Holder”), from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof (including, but not limited to, any
loss, claim, damage, liability or action relating to resales of the Transfer Restricted Securities), to which such Indemnified Holder may become subject, insofar as any such loss, claim, damage, liability or action arises out of, or is based upon:

  
 (i) any untrue statement or alleged untrue
statement of a material fact contained in (A) the Shelf Registration Statement or Prospectus or any amendment or supplement thereto or (B) any blue sky application or other document or any amendment or supplement thereto prepared or executed by the
Company (or based upon written information furnished by or on behalf of the Company expressly for use in such blue sky application or other document or amendment on supplement) filed in any jurisdiction specifically for the purpose of qualifying any
or all of the Transfer Restricted Securities under the securities law of any state or other jurisdiction (such application or document being hereinafter called a “Blue Sky Application”); or 
  
 (ii) the omission or alleged omission to state in the Shelf
Registration Statement, Prospectus or any amendment or supplement thereto, or in any Blue Sky Application, any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which
they were made, not misleading, 

  

 13 

 
and shall reimburse each Indemnified Holder promptly upon demand for any legal or other expenses reasonably incurred by such Indemnified Holder in connection
with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the Company shall not be liable in any such case to the extent that any
such loss, claim, damage, liability or action arises out of, or is based upon, (A) any untrue statement or alleged untrue statement or omission or alleged omission made in the Shelf Registration Statement or Prospectus or amendment or supplement
thereto or Blue Sky Application or other document referred to in Section 6(a)(i) hereof in reliance upon and in conformity with written information furnished to the Company by or on behalf of such Holder specifically for inclusion therein and (B)
the failure of the Indemnified Holder to deliver in a corrective amendment or supplement after delivery by the Company to such Indemnified Holder of such amendment or supplement. The foregoing indemnity agreement is in addition to any liability
which the Company may otherwise have to any Indemnified Holder. 
  
 (b) Each Holder, severally and not jointly, shall indemnify and hold harmless the Company, its officers, directors and employees and each person, if any, who controls the Company within the meaning of the Securities Act, from and against
any loss, claim, damage or liability, joint or several, or any action in respect thereof, to which the Company or any such officer, director, employee or controlling person may become subject, insofar as any such loss, claim, damage or liability or
action arises out of, or is based upon: 
  
 (i)
any untrue statement or alleged untrue statement of any material fact contained in the Shelf Registration Statement or Prospectus or any amendment or supplement thereto or any Blue Sky Application or other document referred to in Section 6(a)(i)
hereof; or 
  
 (ii) the omission or the alleged
omission to state in the Shelf Registration Statement, Prospectus or any amendment or supplement thereto, or in any Blue Sky Application or other document referred to in Section 6(a)(i) hereof, any material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, 
  
 but in each case only to the extent that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity
with written information furnished to the Company by or on behalf of such Holder (or its related Indemnified Holder) specifically for use therein, and shall reimburse the Company and any such officer, employee or controlling person promptly upon
demand for any legal or other expenses reasonably incurred by the Company or any such officer, employee or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or
action as such expenses are incurred. The foregoing indemnity agreement is in addition to any liability which any Holder may otherwise have to the Company and any such officer, employee or controlling person. 
  
 (c) Promptly after receipt by an indemnified party under this Section 6 of
notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Section 6, notify the indemnifying party in writing of the claim or the
commencement of that action; provided, 

  

 14 

 
however, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have under this Section 6 except to
the extent it has been materially prejudiced by such failure and, provided, further, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under this
Section 6. If any such claim or action shall be brought against an indemnified party, and the indemnified party shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it
wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the
defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 6 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other
than reasonable costs of investigation; provided, however, that a Majority of Holders shall have the right to employ a single counsel to represent jointly a Majority of Holders and their respective officers, directors, partners, employees and
controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought by a Majority of Holders against the Company under this Section 6, and, if a Majority of Holders seeking indemnification shall
have been advised by legal counsel that there may be one or more legal defenses available to them and their respective directors, officers, partners, employees and controlling persons that are different from or additional to those available to the
Company and its officers, directors, employees and controlling persons, the fees and expenses of a single separate counsel shall be paid by the Company. No indemnifying party shall: 
  
 (i) without the prior written consent of the indemnified parties (which consent shall not be unreasonably
withheld) settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the
indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or
proceeding, or 
  
 (ii) be liable for any
settlement of any such action effected without its written consent (which consent shall not be unreasonably withheld), but if settled with its written consent or if there be a final judgment for the plaintiff in any such action, the indemnifying
party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment. 
  
 (d) If the indemnification provided for in this Section 6 shall for any reason be unavailable or insufficient to hold harmless an indemnified party under
Section 6(a) or 6(b) in respect of any loss, claim, damage or liability (or action in respect thereof) referred to therein, each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by
such indemnified party as a result of such loss, claim, damage or liability (or action in respect thereof): 
  
 (i) in such proportion as is appropriate to reflect the relative benefits received by the Company from the offering and sale of the
Transfer Restricted Securities 

  

 15 

 
on the one hand and a Holder with respect to the sale by such Holder of the Transfer Restricted Securities on the other, or 
  
 (ii) if the allocation provided by clause (6)(d)(i) is not
permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause 6(d)(i) but also the relative fault of the Company on the one hand and the Holders on the other in connection with the
statements or omissions or alleged statements or alleged omissions that resulted in such loss, claim, damage or liability (or action in respect thereof), as well as any other relevant equitable considerations. 
  
 The relative benefits received by the Company on the one hand and a Holder on the other with
respect to such offering and such sale shall be deemed to be in the same proportion as the total net proceeds from the offering of the Notes purchased under the Purchase Agreement (before deducting expenses) received by the Company on the one hand,
bear to the total proceeds received by such Holder with respect to its sale of Transfer Restricted Securities on the other. The relative fault of the parties shall be determined by reference to whether the untrue or alleged untrue statement of a
material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company on the one hand or the Holders on the other, the intent of the parties and their relative knowledge, access to information and
opportunity to correct or prevent such statement or omission. The Company and each Holder agree that it would not be just and equitable if the amount of contribution pursuant to this Section 6(d) were determined by pro rata allocation or by
any other method of allocation that does not take into account the equitable considerations referred to in the first sentence of this paragraph (d). The amount paid or payable by an indemnified party as a result of the loss, claim, damage or
liability, or action in respect thereof, referred to above in this Section 6 shall be deemed to include, for purposes of this Section 6, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or
defending or preparing to defend any such action or claim. Notwithstanding the provisions of this Section 6, no Holder shall be required to contribute any amount in excess of the amount by which the total price at which the Transfer Restricted
Securities purchased by it were resold exceeds the amount of any damages which such Holder has otherwise been required to pay by reason of any untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Holders’ obligations to contribute as provided in this
Section 6(d) are several and not joint. 
  
 7. Rule
144A. In the event the Company is not subject to Section 13 or 15(d) of the Exchange Act, the Company hereby agrees with each Holder, for so long as any Transfer Restricted Securities remain outstanding, to make available to any Holder or
beneficial owner of Transfer Restricted Securities in connection with any sale thereof and any prospective purchaser of such Transfer Restricted Securities from such Holder or beneficial owner, the information required by Rule 144A(d)(4) under the
Securities Act in order to permit resales of such Transfer Restricted Securities pursuant to Rule 144A. 
  

 16 

 8. Participation in Underwritten Registrations. No Holder may participate in any
Underwritten Registration hereunder unless such Holder: 
  
 (i) agrees to sell such Holder’s Transfer Restricted Securities on the basis provided in any underwriting arrangements approved by the Persons entitled hereunder to approve such arrangements; and 
  
 (ii) completes and executes all reasonable questionnaires,
powers of attorney, indemnities, underwriting agreements, lock-up letters and other documents required under the terms of such underwriting arrangements. 
  
 9. Miscellaneous. 
  
 (a) Remedies. The Company acknowledges and agrees that any failure by the Company to comply with its obligations under Section 2 hereof may
result in material irreparable injury to the Initial Purchasers or the Holders for which there is no adequate remedy at law, that it will not be possible to measure damages for such injuries precisely and that, in the event of any such failure, the
Initial Purchasers or any Holder may obtain such relief as may be required to specifically enforce the Company’s obligations under Section 2 hereof. The Company further agrees to waive the defense in any action for specific performance that a
remedy at law would be adequate. 
  
 (b) Actions Affecting
Transfer Restricted Securities. The Company shall not, directly or indirectly, take any action with respect to the Transfer Restricted Securities as a class that would adversely affect the ability of the Holders of Transfer Restricted
Securities to include such Transfer Restricted Securities in a registration undertaken pursuant to this Agreement. 
  
 (c) No Inconsistent Agreements. The Company will not, on or after the date of this Agreement, enter into any agreement with respect to its
securities that is inconsistent with the rights granted to the Holders in this Agreement or otherwise conflicts with the provisions hereof; provided, however, that the Company shall be permitted to grant registration rights to the holder of up to
$350,000 of Common Stock of the Company (the “Included Stock”) which may be included in the Shelf Registration Statement provided that the inclusion of the Included Stock does not prejudice in any material respect the rights of the Holders
of Transfer Restricted Securities arising under this Agreement. In addition, other than in connection with the issuance of the Included Stock, the Company shall not grant to any of its security holders (other than the Holders of Transfer Restricted
Securities in such capacity) the right to include any of its securities in the Shelf Registration Statement provided for in this Agreement other than the Transfer Restricted Securities. The Company has not previously entered into any agreement
(which has not expired or been terminated) granting any registration rights with respect to its securities to any Person which rights conflict with the provisions hereof. 
  
 (d) Amendments and Waivers. This Agreement may not be amended, modified or supplemented, and waivers or
consents to or departures from the provisions hereof may not be given, unless the Company has obtained the written consent of a Majority of Holders or such greater percentage of the Holders as required by the Indenture.

 (f) Successors and Assigns. This Agreement shall inure to the benefit of and be binding upon the successors and assigns of each of the parties, including without limitation and without the need for an
express assignment, subsequent Holders of Transfer Restricted Securities; provided, however, that (i) this Agreement shall not inure to the benefit of or be binding upon a successor or assign of a Holder unless and to the extent such
successor or assign acquired Transfer Restricted Securities from such Holder and (ii) nothing contained herein shall be deemed to permit any assignment, transfer or other disposition of Transfer Restricted Securities in violation of the terms of the

required percentage.
