 (4)

 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 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. 
 ARTICLE II 

THE SECURITIES 
 Section 2.1 Form
and Dating. The Securities and the Trustee’s certificate of authentication shall be substantially in the form of Exhibits A and B, which are a part of this Indenture. The Securities may have notations, legends or endorsements required by
law, stock exchange rule or usage (provided that any such notation, legend or endorsement required by usage is in a form acceptable to the Company). The Company shall provide any such 

  

 5 








 
notations, legends or endorsements to the Trustee in writing. Each Security shall be dated the date of its authentication. The Securities are being offered
by the Company in exchange for an equal principal amount of similar debt securities (the “Existing Securities”) tendered in exchange therefor by the holders thereof. 
 (a) Restricted Global Securities. Each Security issued in exchange for an Existing Security shall be issued initially in the form of one or more
Restricted Global Securities, which shall be deposited on behalf of the acquirers of the Securities represented thereby with the Trustee at its Corporate Trust Office, as custodian for the Depositary (as defined below) and registered in the name of
The Depository Trust Company (“DTC”) or the nominee thereof DTC, or any successor thereto, and any such nominee being hereinafter referred to as the “Depositary”), duly executed by the Company and authenticated by the Trustee as
hereinafter provided. The aggregate principal amount of the Restricted Global Securities may from time to time be increased or decreased by adjustments made on the records of the Trustee and the Depositary as hereinafter provided. 
 (b) Global Securities in General. Each Global Security shall represent such of the outstanding Securities as shall be specified therein and each
shall provide that it shall represent the aggregate amount of outstanding Securities from time to time endorsed thereon and that the aggregate amount of outstanding Securities represented thereby may from time to time be reduced or increased, as
appropriate, to reflect exchanges, redemptions, repurchases and conversions. 
 Any adjustment of the aggregate principal amount of a Global
Security to reflect the amount of any increase or decrease in the amount of outstanding Securities represented thereby shall be made by the Trustee in accordance with instructions given by the Holder thereof as required by Section 2.12 hereof
and shall be made on the records of the Trustee and the Depositary. 
 (c) Book-Entry Provisions. This Section 2.1(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 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 $72,000,000 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 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. 
  

 7 








 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 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. 
 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 

  

 8 








 
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. 
 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. 
  

 9 








 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 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. 
  

 10 








 (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 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 
  

 11 








 (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 

  

	 	(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 qualified institutional buyer as defined in Rule
144A (“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 
  

 12 








 (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 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 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

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

 (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. 
 Section 2.14. Ranking of Securities in Relation to Existing Securities. The Securities shall rank pari passu in right of payment with
the Existing Securities. 
 ARTICLE III 
 REDEMPTION AND PURCHASES 
 Section 3.1 Company’s Right to Redeem; Notices to Trustee. Prior to July 15, 2008,
the Securities will not be redeemable at the Company’s option. Beginning on July 15, 2008, 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. 
  

 14 








 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 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; 

  

	 	(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. 

  

 15 








 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). 
 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:

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 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.

Directors who:

 (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 (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 Global 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;

	 	(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; 

  

 17 









	 	(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;

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 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

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

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

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

satisfaction.

 22 








 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 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. 
  

 23 








 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; 

  

	 	(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 
 (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. 
  

 24 








 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 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.

 25 









	 	 
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:

 (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.

 (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;

liabilities which may be incurred therein or thereby; 
  

 26 








 (g) any request or direction of the Company mentioned herein shall be sufficiently evidenced by a Company

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

 (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

 (j) the rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are

 (l) in no event shall the Trustee be responsible or liable for special, indirect, or consequential loss or damage of any kind whatsoever

 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. 
 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).

  

 27 








 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 shall be determined to have been caused by its negligence, bad faith or willful misconduct; and 
 (c) to indemnify the Trustee or any predecessor Trustee and their agents for, and to hold them harmless against, any loss, damage, claim, liability, cost
or expense (including 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, 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. 
  

 28 








 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 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

 (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

 Without the written consent or the affirmative vote of each Holder of Securities affected thereby, an

 (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. 
 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. 
  

 30 








 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 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. 
  

 31 








 (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. 
 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 
  

 32 








 (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.

 (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 

  

 33 








 
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 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 
 (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

  

 34 








 (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 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 Conversion Price shall equal the price determined by multiplying the Conversion Price in effect immediately prior to the Expiration Time by a fraction, 
  

 35 








 (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 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 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; 
  

 36 








 (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 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. 
  

 37 








 (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); 
 (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. 
 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 (as
defined in Section 2.3) 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 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 Delaware, 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. 
  

 39 








 (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 NASDAQ Global Market, 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 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 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 2009 
 This Security is one of a duly authorized issue of the 6.25% Convertible Senior Notes due 2009 (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 August 6, 2007 (the “Indenture”), between the Company and The Bank of New York Trust Company, N.A., as trustee (the “Trustee”). The terms
of the Security include those stated in the Indenture, those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (“TIA”), and those set forth in this Security. This Security is subject to all such terms,
and Holders are referred to the Indenture and the TIA for a statement of all such terms. To the extent permitted by applicable law, in the event of any inconsistency between the terms of this Security and the terms of the Indenture, the terms of the
Indenture shall control. Capitalized terms used but not defined herein have the meanings assigned to them in the Indenture referred to below unless otherwise indicated. 
 1. Interest  
 The 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, 2009, 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, 2008. 
 The Securities shall bear interest from                     , 2007 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 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 which has accrued and will be paid on such interest payment date; provided, that no such 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 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. 
  

 A-3 








 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 Securities will be payable, upon Stated Maturity or when due, at the office or agency of the Company in New York City, maintained for such purpose,
initially the Corporate Trust Office of the Trustee in New York City. 
 Subject to the terms and conditions of the Indenture, the Company
will make payments in cash in respect of Redemption Prices, Change of Control Purchase Prices and at Stated Maturity to Holders who surrender Securities to a Paying Agent to collect such payments in respect of the Securities. The Company will pay
cash amounts in money of the United States that at the time of payment is legal tender for payment of public and private debts. However, the Company may make such cash payments by check payable in such money. 
 3. Paying Agent, Conversion Agent and Registrar. 
 Initially, The Bank of New York Trust Company, N.A. will act as Paying Agent, Conversion Agent and Registrar. The Company may appoint and change any Paying Agent, Conversion Agent or Registrar without notice, other than notice to the
Trustee; provided that the Company will maintain at least one Paying Agent in the State of New York, City of New York, Borough of Manhattan, which shall initially be an office or agency of the Trustee. The Company or any of its Subsidiaries or any
of their Affiliates may act as Paying Agent, Conversion Agent or Registrar. 
 4. Indenture.  
 The Securities are senior unsecured obligations of the Company limited to up to $72,000,000 aggregate principal amount. 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 15, 2008. 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 15, 2008 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 up to the Redemption Date (the “Redemption Price”); provided, that the Current Market Value for the Common Stock equals or exceeds $8.50
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 Global 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 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. 
  

 A-4 








 7. Notice of Redemption. 
 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 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 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. 
  

 A-5 








 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. 
 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. 
 17. Abbreviations. 
 Customary abbreviations may be
used in the name of a Securityholder or an assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the entireties), JT TEN (=joint tenants with right of survivorship and not as tenants in common), CUST (=custodian), and U/G/M/A
(=Uniform Gift to Minors Act). 
 18. GOVERNING LAW. 
 THIS SECURITY AND THE INDENTURE SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.
