 SECTION 1.03. Compliance Certificates and Opinions. Upon any application or
request by the Company to the Trustee to take any action under any provision of this Indenture, the Company shall furnish to the Trustee an Officers’ Certificate stating that all conditions precedent, if any, provided for in this Indenture
relating to the proposed action have been complied with and an Opinion of Counsel stating that in the opinion of such counsel all such conditions precedent, if any, have been complied with, except that in the case of any such application or request
as to which the furnishing of such documents is specifically required by any provision of this Indenture relating to such particular application or request, no additional certificate or opinion need be furnished. 
 Every certificate or opinion with respect to compliance with a condition or covenant provided for in this Indenture shall include: 
 (a) a statement that each individual signing such certificate or opinion has read such condition or covenant and the definitions herein
relating thereto; 
 (b) a brief statement as to the nature and scope of the examination or investigation upon which the
statements or opinions contained in such certificate or opinion are based; 
 (c) a statement that, in the opinion of each
such individual, he has made such examination or investigation as is necessary to enable him to express an informed opinion as to whether or not such condition or covenant has been complied with; and 
 (d) a statement as to whether, in the opinion of each such individual, such condition or covenant has been complied with. 
 SECTION 1.04. Form of Documents Delivered to Trustee. In any case where several matters are required to be certified by, or covered by
an opinion of, any specified Person, it is not necessary that all such matters be certified by, or covered by the opinion of, only one such Person, or that they be so certified or covered by only one document, but one such Person may certify or give
an opinion as to some matters and one or more other such Persons as to other matters, and any such Person may certify or give an opinion as to such matters in one or several documents. 
 Any certificate or opinion of an officer of the Company may be based, insofar as it relates to legal matters, upon an Opinion of Counsel, or a
certificate or representations by counsel, unless such officer knows, or in the 

  

 6 








 
exercise of reasonable care should know, that the opinion, certificate or representations with respect to the matters upon which such certificate or opinion
is based are erroneous. Any such Opinion of Counsel or certificate or representations may be based, insofar as it relates to factual matters, upon a certificate or opinion of, or representations by, an officer or officers of the Company stating that
the information as to such factual matters is in the possession of the Company, unless such counsel knows that the certificate or opinion or representations as to such matters are erroneous. 
 Where any Person is required to make, give or execute two or more applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and form one instrument. 
 SECTION 1.05. 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 of the Outstanding Securities may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by agents duly appointed in writing. 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. Such instrument or instruments (and the action
embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent, or of
the holding by any Person of a Security, shall be sufficient for any purpose of this Indenture and conclusive in favor of the Trustee and the Company and any agent of the Trustee or the Company, if made in the manner provided in this
Section 1.05. 
 (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 to 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 him the
execution thereof. Where such execution is by a signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient proof of his 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 reasonable manner which the Trustee deems sufficient. 
 (c) The ownership of the Securities shall be proved by the Security Register. 
 (d)(i) 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, in or pursuant to a Board Resolution, fix in advance a record date for the determination of Holders entitled to effect such request, demand, authorization, direction, notice, consent, waiver or other Act, but the
Company shall have no obligation to do so; provided that the Company shall not be entitled to set a record date for, and the provisions of this paragraph shall not apply with respect to, the giving or making of any notice, declaration,
request or direction referred to in clause 1.05(d)(iii) below. Notwithstanding TIA Section 316(c), such record date shall be the record date specified in or pursuant to such Board Resolution, which shall be a date not earlier than the date 30
days prior to the first solicitation of Holders generally in connection therewith and not later than the date such solicitation is completed. If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or
other Act may be effected 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 eleven months after the record
date. 
  

 7 








 (ii) Subject to clause 1.05(d)(iii) below, in the absence of any such record date
fixed by the Company, regardless as to whether any solicitation of the Holders is occurring on behalf of the Company or any Holder, the Trustee may, at its option, fix in advance a record date for the determination of such Holders entitled to give
such request, demand, authorization, direction, notice, consent, waiver or other Act, but the Trustee shall have no obligation to do so. Any such record date shall be a date not more than 30 days prior to the first solicitation of Holders generally
in connection therewith and no later than the date of such solicitation. 
 (iii) The Trustee may set any day as a record
date for the purpose of determining the Holders of Outstanding Securities entitled to join in the giving or making of (A) any notice of default, (B) any declaration of acceleration referred to in Section 4.02, (C) any request to
institute proceedings referred to in Section 4.07(b), or (D) any direction referred to in Section 4.12, and may also set an expiration date by which the relevant Act must be taken. If any record date is set pursuant to this paragraph,
the Holders of Outstanding Securities on such record date, and no other Holders, shall be entitled to join in such notice, declaration, request or direction, whether or not such Holders remain Holders after such record date; provided that no
such Act shall be effective hereunder unless taken on or prior to any applicable expiration date by Holders of the requisite principal amount of Outstanding Securities on such record date. Nothing in this paragraph shall be construed to prevent the
Trustee from setting a new record date for any action (whereupon the record date previously set shall automatically and without any action by any Person be canceled and of no effect), nor shall anything in this paragraph be construed to render
ineffective any Act taken by Holders of the requisite principal amount of Outstanding Securities on the date such Act is taken. Promptly after any record date is set pursuant to this paragraph, the Trustee, at the Company’s expense, shall cause
notice of such record date, the proposed Act by Holders and the applicable expiration date to be given to the Company in writing and to each Holder of Outstanding Securities in the manner set forth in Section 1.07. 
 (e) 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, any Security
Registrar, any Paying Agent, any Conversion Agent or the Company in reliance thereon, whether or not notation of such action is made upon such Security. 
 SECTION 1.06. Notices, Etc to Trustee and Company. 
 Any request, demand, authorization,
direction, notice, consent, waiver or other Act of Holders or other notice or communication provided or permitted by this Indenture to be made upon, given or furnished to, or filed with: 
 (a) the Trustee by any Holder or by the Company shall be sufficient for every purpose hereunder if made, given, furnished or filed in
writing to or with the Trustee, delivered in person, mailed by first class mail, postage prepaid, or sent by facsimile or overnight courier, at its address as follows: if mailed by first class mail, to U.S. Bank National Association, Corporate Trust
Services, P.O. Box 960778, Boston, MA 02102-0778, Attention: TranSwitch Corporation 5.45% Convertible Notes due 2010, or if sent by other means to U.S. Bank National Association, Corporate Trust Services, One Federal Street, 3rd Floor, Boston, MA
02110, Attention: Corporate Trust Services/ David J. Ganss, Attention: TranSwitch Corporation 5.45% Convertible Notes due 2010 (facsimile: 617-603-6667), or to such other address or facsimile number as the Trustee may designate by written notice
from time to time; provided that notices or other communications to the Trustee shall only be deemed given when actually received by the Trustee, 
 (b) the Company by the Trustee or by any Holder shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if in writing and delivered in person, mailed by first class mail, postage
prepaid, or sent by facsimile or overnight courier, to the Company addressed to it at the address of its principal office specified in the first paragraph of this Indenture; provided that the Company may, by 

  

 8 








 
notice furnished in writing to the Trustee, designate additional or different addresses for subsequent notices or communications by the Company; and
further provided that notices or other communications to the Company shall only be deemed given when actually received by the Company. 
 SECTION 1.07. Notice to Holders; Waiver. Where this Indenture provides for notice of any event to Holders by the Company or the Trustee, such notice shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid, to each such Holder affected by such event, at his address as it appears in the Security Register, not later than the latest date, and not earlier than the earliest date, prescribed for the
giving of such notice. Such notice shall be deemed to have been given when such notice is mailed. In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any
particular Holder shall affect the sufficiency of such notice with respect to other Holders given as provided herein. Any notice mailed to a Holder in the manner herein prescribed shall be conclusively deemed to have been received by such Holder,
whether or not such Holder actually receives such notice. 
 If by reason of the suspension of or irregularities in regular mail service or
by reason of any other cause it shall be impracticable to give such notice by mail, then such notification to Holders as shall be made with the approval of the Trustee shall constitute a sufficient notification to such Holders for every purpose
hereunder. 
 Any request, demand, authorization, direction, notice, consent, waiver or other Act required or permitted under this Indenture
shall be in the English language, except that any published notice may be in an official language of the country of publication. 
 Where
this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by
Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver. 
 SECTION 1.08. Effect of Headings and Table of Contents. The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof.

 SECTION 1.09. Successors and Assigns. All covenants and agreements in this Indenture by the Company shall bind its
successors and assigns, whether so expressed or not. 
 SECTION 1.10. Separability Clause. In case any provision in this
Indenture or in any Security shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. 
 SECTION 1.11. Benefits of Indenture. Nothing in this Indenture or in the Securities, express or implied, shall give to any Person, other
than the parties hereto, any Security Registrar, any Paying Agent, any Conversion Agent and their successors hereunder and the Holders any benefit or any legal or equitable right, remedy or claim under this Indenture. 
 SECTION 1.12. Governing Law. This Indenture and the Securities shall be governed by and construed in accordance with the law of the
State of New York without regard to conflict of laws principles. 
 SECTION 1.13. Legal Holidays. In any case where any
Interest Payment Date, Redemption Date, Repurchase Date, Stated Maturity or Maturity of any Security or the last date on which a Holder has the right to convert his Securities shall not be a Business Day at any Place of Payment, then
(notwithstanding any other provision of this Indenture or any Security), payment of Redemption Price, Repurchase Price, interest (including any Liquidated Damages) or principal (and premium, if any), or conversion of the Securities, need not be made
at 

  

 9 








 
such Place of Payment on such date, but may be made on the next succeeding Business Day at such Place of Payment with the same force and effect as if made on
the Interest Payment Date, Redemption Date, Repurchase Date or at the Stated Maturity or Maturity or on such last day for conversion; provided that no interest shall accrue on the amount so payable for the period from and after such Interest Payment
Date, Redemption Date, Repurchase Date, Stated Maturity or Maturity or on such last day for conversion, as the case may be. 
 SECTION 1.14. Personal Immunity from Liability for Incorporators, Stockholders, Etc. No recourse shall be had for the payment of the principal of or premium, if any, or interest (including any Liquidated Damages), if any, on any
Security, or for any claim based thereon, or otherwise in respect of any Security, or based on or in respect of this Indenture or any indenture supplemental hereto, against any incorporator, or against any past, present or future stockholder,
director or officer, as such, of the Company or of any successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise, all such liability being expressly waived
and released as a condition of, and as consideration for, the execution of this Indenture and the issue of Securities. 
 SECTION 1.15.
Conflict with Trust Indenture Act. If any provision hereof limits, qualifies or conflicts with a provision of the TIA that is required under such Act to be a part of and govern this Indenture, the latter provision shall control. If any
provision of this Indenture modifies or excludes any provision of the TIA that may be so modified or excluded, the latter provision shall be deemed to apply to this Indenture as so modified or to be excluded, as the case may be. To the extent that
any provision of a Security conflicts with a provision in this Indenture, the provision of this Indenture shall control. 
 SECTION 1.16. Execution in Counterparts. This Indenture may be executed in any number of counterparts, each of which shall be an original, but such counterparts shall together constitute but one and the same instrument.

 ARTICLE 2 
 SECURITIES FORMS 
 SECTION 2.01. Forms of Securities. The Securities shall be

		 		 	 as Trustee

				
		 		 	By:  	 	  
		 		 		 		 	Authorized Signatory

 SECTION 2.03. Securities Issuable in Global Form. Except as otherwise provided in
this Section 2.03 or in Section 3.04, the Securities shall be issuable only in global form and deposited with the Trustee, at its Corporate Trust Office (or such other location as it may determine from time to time for such purpose), as
custodian for DTC or the nominees thereof, and any such Security shall represent such of the Outstanding Securities as shall be set forth in the books and records of the Trustee and may provide that it shall represent the aggregate amount of
Outstanding Securities from time to time as adjusted in the books and records of the Trustee, and that the aggregate amount of Outstanding Securities represented thereby may from time to time be increased or decreased to reflect exchanges.

  

 10 








 Notwithstanding anything to the contrary contained herein, each of the Company’s and any
Holder’s obligations or exercise of any right or procedure described herein shall be made in accordance with and subject to the procedures of the Trustee and the depository or the nominees thereof. Members of, or participants in, the depositary
(“Agent Members”) shall have no rights under this Indenture with respect to any Note in global form held on their behalf by the depositary or by the Trustee as the custodian of the depositary or under such Note in global form, and
the depositary may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner of such Note 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 impair, as between the depositary and its Agent Members, the operation of customary
practices of such depositary governing the exercise of the rights of a holder of a beneficial interest in any Note held in global form. Any adjustment of the aggregate amount of Outstanding Securities represented by a Security in global form to
reflect the amount, or any increase or decrease in the amount, of Outstanding Securities represented thereby shall be made by the Trustee in such manner and upon instructions given by such Person or Persons as shall be specified therein or in the
Company Order to be delivered to the Trustee pursuant to Section 3.03. Subject to the provisions of Section 3.03, the Trustee shall, if required, deliver and redeliver any Security in global form in the manner and upon instructions given
by the Person or Persons specified therein or in the applicable Company Order. If a Company Order pursuant to Section 3.03 has been, or simultaneously is, delivered, any instructions by the Company with respect to endorsement or delivery or
redelivery of a Security in global form shall be in writing but need not comply with Section 1.03 and need not be accompanied by an Opinion of Counsel. 
 The provisions of the last sentence of Section 3.03 shall apply to any Security represented by a Security in global form if such Security was never issued and sold by the Company and the Company delivers to the
Trustee the Security in global form together with written instructions (which need not comply with Section 1.03 and need not be accompanied by an Opinion of Counsel) with regard to the reduction in the principal amount of Securities represented
thereby, together with the written statement contemplated by the last sentence of Section 3.03. 
 Notwithstanding the provisions of
Section 3.07, payment of principal of and any premium and interest (including any Liquidated Damages) on any Security in global form shall be made to the Person or Persons specified in such Security. 
 All Securities issued in global form shall bear the following legend: 
 UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION (“DTC”), NEW YORK, NEW YORK, TO THE COMPANY OR ITS AGENT FOR REGISTRATION OF
TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC, AND ANY PAYMENT IS MADE TO CEDE & CO. OR TO SUCH OTHER
ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC, ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL BECAUSE THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.

 TRANSFERS OF THIS GLOBAL SECURITY SHALL BE LIMITED TO TRANSFERS IN WHOLE, BUT NOT IN PART, TO NOMINEES OF CEDE & CO. OR TO A
SUCCESSOR THEREOF OR SUCH SUCCESSOR’S NOMINEE. 
  

 11 








 ARTICLE 3 
 THE SECURITIES 
 SECTION 3.01. Title and Term. The
Securities shall be and are hereby authorized to be designated as “5.45% Convertible Notes due 2010.” The Securities are limited in aggregate principal amount to $25,013,000. The Securities shall mature and the principal thereof shall be
due and payable, together with all accrued and unpaid interest thereon, on September 30, 2010. The Securities shall be convertible into shares of Common Stock as set forth herein. The Securities are entitled to the payment of Liquidated Damages
as set forth herein and in the Registration Rights Agreement. 
 SECTION 3.02. Denominations. The Securities shall be
issuable in denominations of $1,000 and any integral multiple thereof. 
 SECTION 3.03. Execution, Authentication, Delivery and
Dating. The Securities shall be executed on behalf of the Company by the Chief Executive Officer, the Chief Financial Officer, the Treasurer, the President or a Vice President of the Company. The signature of any of these individuals on the
Securities may be a manual or facsimile signature of such authorized officer and may be imprinted or otherwise reproduced on the Securities. 
 Securities bearing the manual or facsimile signatures of an individual who was at any time the proper officer of the Company shall bind the Company, notwithstanding that such individual shall have ceased to hold such office prior to the
authentication and delivery of such Securities or did not hold such office at the date of such Securities. 
 At any time and from time to
time after the execution and delivery of this Indenture, the Company may deliver Securities, executed by the Company, to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Securities, and the
Trustee in accordance with the Company Order shall authenticate and deliver such Securities. 
 Each Security shall be dated the date of its
authentication. 
 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 in Section 2.02, 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 and is entitled to the benefits of this Indenture. Notwithstanding the foregoing, if any Security shall have been authenticated and
delivered hereunder but never issued and sold by the Company, and the Company shall deliver such Security to the Trustee for cancellation as provided in Section 3.08 together with a written statement (which need not comply with
Section 1.03 and need not be accompanied by an Opinion of Counsel) stating that such Security has never been issued and sold by the Company, for all purposes of this Indenture, such Security shall be deemed not to have been authenticated and
delivered hereunder and shall never be entitled to the benefits of this Indenture. 
 SECTION 3.04. Registration, Registration of
Transfer and Exchange.
 (a) The Company shall cause to be kept at the Corporate Trust Office of the Trustee or in any
office or agency of the Company in a Place of Payment a register for the Securities (the “Security Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of
the Securities and of transfers of the Securities. The Security Register shall be in written form or any other form capable of being converted into written form within a reasonable time. The Trustee, at its Corporate Trust Office, is hereby
appointed “Security Registrar” for the purpose of registering the 

  

 12 








 
Securities and transfers of the Securities on such Security Register as herein provided. In the event that the Trustee shall cease to be Security Registrar,
it shall have the right to examine the Security Register at all reasonable times. 
 Subject to the provisions of this Section 3.04 and
except as otherwise provided in any Security, including any legend thereon, upon surrender for registration of transfer of any Security at any office or agency of the Company in a Place of Payment, 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 denominations and of a like aggregate principal amount, bearing a number not contemporaneously outstanding, and
containing identical terms and provisions. 
 Subject to the provisions of this Section 3.04, at the option of the Holder, the
Securities may be exchanged for other Securities, of any authorized denomination or denominations and of a like aggregate principal amount, containing identical terms and provisions, upon surrender of the Securities to be exchanged at any such
office or agency. Whenever any such Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Securities that the Holder making the exchange is entitled to receive. 
 Notwithstanding the foregoing, any global Security shall be exchangeable only as provided in this paragraph. The depositary for the global Securities
shall be DTC, and the global Securities may be transferred, in whole but not in part, only to a nominee of DTC, or by a nominee of DTC to DTC, or to a successor to DTC for such global Security selected or approved by the Company or to a nominee of
such successor to DTC. If at any time DTC notifies the Company that it is unwilling or unable to continue as depositary for the applicable global Security or Securities or if at any time DTC ceases to be a clearing agency registered under the
Exchange Act, if so required by applicable law or regulation, the Company shall appoint a successor depositary with respect to such global Security or Securities. If (x) a successor depositary for such global Security or Securities is not
appointed by the Company within 90 days after the Company receives such notice or becomes aware of such unwillingness, inability or ineligibility, or (y) a Default or an Event of Default has occurred and is continuing, or (z) the Company,
in its sole discretion, executes and delivers to the Trustee and the Security Registrar an Officers’ Certificate stating that definitive Securities may be issued in exchange for interests in a global Security or Securities, then the Company
shall execute, and the Trustee shall authenticate and deliver, definitive Securities of like rank, tenor and terms in definitive form, registered in such names as DTC shall direct and bearing such legends as the Company shall specify in writing, in
an aggregate principal amount equal to the principal amount of such global Security or Securities. If a Security is issued in exchange for any portion of a global Security after the close of business at the office or agency where such exchange
occurs on (i) any Regular Record Date and before the opening of business at such office or agency on the relevant Interest Payment Date or (ii) any Special Record Date and before the opening of business at such office or agency on the
related proposed date for payment of Defaulted Interest, interest or Defaulted Interest, as the case may be, shall not be payable on such Interest Payment Date or proposed date for payment, as the case may be, in respect of such Security, but will
be payable on such Interest Payment Date or proposed date for payment, as the case may be, only to the Person to whom interest in respect of such portion of such global Security is payable in accordance with the provisions of this Indenture.

 All Securities issued upon any registration of transfer or exchange of Securities shall be the valid obligations of the Company,
evidencing the same debt, and entitled to the same benefits under this Indenture, as the Securities surrendered upon such registration of transfer or exchange. 
 Every Security presented or surrendered for registration of transfer or for exchange or redemption shall (if so required by the Company or the Security Registrar) be duly endorsed, or be accompanied by a written
instrument of transfer, in form satisfactory to the Company and the Security Registrar, duly executed by the Holder thereof or his attorney duly authorized in writing. 
  

 13 








 No service charge shall be made to a Holder for any registration of transfer or exchange of Securities,
but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 10.07
or 11.02(e) not involving any transfer. 
 The Company or the Trustee, as applicable, shall not be required (i) to issue, register the
transfer of or exchange any Security during a period beginning at the opening of business 15 days before the date of the mailing of a notice of redemption with respect to the Securities to be redeemed under Section 10.03 and ending at the close
of business on the day of the mailing of the relevant notice of redemption, or (ii) to register the transfer of or exchange any Security so selected for redemption in whole or in part, except, in the case of any Security to be redeemed in part,
the portion thereof not to be redeemed, or (iii) to issue, register the transfer of or exchange any Security that has been surrendered for repayment at the option of the Holder, except the portion, if any, of such Security not to be so repaid.

 (b) Every Security that bears or is required under this Section 3.04(b) to bear the legend set forth in this
Section 3.04(b) (together with any Common Stock issued upon conversion or exchange of the Securities and required to bear the legend set forth in Section 3.04(c), collectively, the “Restricted Securities”) shall be subject
to the restrictions on transfer set forth in this Section 3.04(b) (including one of the legends set forth below), unless such restrictions on transfer shall be waived by written consent of the Company, and the holder of each such Restricted
Security, by such holder’s acceptance thereof, agrees to be bound by all such restrictions on transfer. As used in Sections 3.04(b) and 3.04(c), the term “transfer” encompasses any sale, pledge, transfer or other disposition
whatsoever of any Restricted Security. Upon the effectiveness of a filed registration statement covering the Securities, the Company shall deliver an Officers’ Certificate to the Trustee in a form reasonably satisfactory to the Trustee
informing the Trustee of the effectiveness of such registration and instructing the Trustee regarding the issuance and delivery of unlegended Securities. 
 Until two years after the original issuance date of any Security, any certificate evidencing such Security (and all securities issued in exchange therefor or substitution thereof, other than Common Stock, if any,
issued upon conversion thereof, which shall bear the legend set forth in Section 3.04(c), if applicable) shall bear a legend in substantially the following form (unless such Securities have been transferred pursuant to a registration statement
that has been declared effective under the Securities Act (and which continues to be effective at the time of such transfer), or pursuant to the exemption from registration provided by Rule 144 under the Securities Act (as evidenced by such
certifications or other information as the Company may reasonably require), with instruction to remove the legend having been given to the Trustee by the Company in the form of an Officers’ Certificate, or unless otherwise agreed by the Company
in writing, with notice thereof to the Trustee in the form of an Officers’ Certificate): 
 THE SECURITY EVIDENCED HEREBY HAS NOT BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR ANY STATE SECURITIES LAWS AND MAY NOT BE OFFERED OR SOLD EXCEPT AS SET FORTH IN THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF, THE HOLDER
(1) AGREES THAT IT WILL NOT WITHIN TWO YEARS AFTER THE ORIGINAL ISSUANCE OF THE SECURITY EVIDENCED HEREBY RESELL OR OTHERWISE TRANSFER THE SECURITY EVIDENCED HEREBY OR THE COMMON STOCK ISSUABLE UPON CONVERSION OR EXCHANGE OF SUCH SECURITY
EXCEPT (A) TO THE COMPANY OR ANY SUBSIDIARY THEREOF, (B) TO A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, (C) PURSUANT TO THE EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE
SECURITIES ACT (IF AVAILABLE), (D) PURSUANT TO ANOTHER EXEMPTION FROM REGISTRATION, OR (E) PURSUANT TO A REGISTRATION STATEMENT THAT HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT (AND WHICH CONTINUES TO BE EFFECTIVE AT THE TIME OF
SUCH TRANSFER); AND (3) AGREES THAT IT WILL DELIVER TO EACH PERSON TO WHOM THE SECURITY EVIDENCED HEREBY IS TRANSFERRED (OTHER THAN A TRANSFER PURSUANT TO CLAUSE 2(E) ABOVE) A

NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. IN CONNECTION WITH ANY TRANSFER OF THE SECURITY EVIDENCED HEREBY WITHIN TWO YEARS AFTER THE ORIGINAL
ISSUANCE OF SUCH SECURITY (OTHER THAN A TRANSFER PURSUANT TO CLAUSE 2(D) ABOVE), THE HOLDER MUST CHECK THE APPROPRIATE BOX SET FORTH ON THE REVERSE HEREOF RELATING TO THE MANNER OF SUCH TRANSFER AND SUBMIT THIS CERTIFICATE TO U.S. BANK NATIONAL
ASSOCIATION, AS TRUSTEE. IF THE PROPOSED TRANSFER IS PURSUANT TO CLAUSE 2(C) OR 2(D) ABOVE, THE HOLDER MUST, PRIOR TO SUCH TRANSFER, FURNISH TO U.S. BANK NATIONAL ASSOCIATION, AS TRUSTEE, SUCH CERTIFICATIONS OR OTHER INFORMATION (OR, IN THE CASE OF
A TRANSFER PURSUANT TO CLAUSE 2(D), SUCH LEGAL OPINIONS) AS THE COMPANY MAY REASONABLY REQUIRE TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE
SECURITIES ACT. THIS LEGEND WILL BE REMOVED UPON THE EARLIER OF THE TRANSFER OF THE SECURITY EVIDENCED HEREBY PURSUANT TO CLAUSE 2(C) OR 2(E) ABOVE OR THE EXPIRATION OF TWO YEARS FROM THE ORIGINAL ISSUANCE OF THE SECURITY EVIDENCED HEREBY.

 Any Security (or Security issued in exchange or substitution therefor) as to which such restrictions on transfer shall have expired or
terminated in accordance with their terms may, upon surrender of such Security for exchange to the Security Registrar in accordance with the provisions of this Section 3.04, be exchanged for a new Security or Securities, of like tenor and
aggregate principal amount, which shall not bear the restrictive legend required by this Section 3.04(b). 
 At such time as all
interests in the global Security have been redeemed, converted, canceled, repurchased or transferred, the global Security shall be, upon receipt thereof, canceled by the Trustee in accordance with standing procedures and instructions existing
between the depositary and the Custodian. 
 (c) Until two years after the original issuance date of any Security, any stock
certificate representing Common Stock issued upon conversion or exchange of such Security shall bear a legend in substantially the following form (unless such Common Stock has been or is being transferred or sold pursuant to the exemption from
registration provided by Rule 144 under the Securities Act (as evidenced by such certifications or other information as the Company may require), with written instruction to remove the legend having been given by the Company to its transfer agent,
or pursuant to a registration statement that has been declared effective under the Securities Act, and which continues to be effective at the time of such transfer, or such Common Stock has been issued upon conversion or exchange of Securities that
have been transferred pursuant to a registration statement that has been declared effective under the Securities Act, or unless otherwise agreed by the Company with written notice thereof to the Trustee (in the form of an Officers’ Certificate)
and any transfer agent for the Common Stock): 
 THE COMMON STOCK EVIDENCED HEREBY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933,
AS AMENDED (THE “SECURITIES ACT”), OR ANY STATE SECURITIES LAWS AND MAY NOT BE OFFERED OR SOLD EXCEPT AS SET FORTH IN THE FOLLOWING SENTENCE. THE HOLDER HEREOF AGREES THAT UNTIL THE EXPIRATION OF TWO YEARS AFTER THE ORIGINAL ISSUANCE OF
THE SECURITY UPON THE CONVERSION OR EXCHANGE OF WHICH THE COMMON STOCK EVIDENCED HEREBY WAS ISSUED, (1) IT WILL NOT RESELL OR OTHERWISE TRANSFER THE COMMON STOCK EVIDENCED HEREBY EXCEPT (A) TO THE COMPANY OR ANY SUBSIDIARY THEREOF,
(B) IN ACCORDANCE WITH THE EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT, (D) PURSUANT TO ANOTHER EXEMPTION FROM REGISTRATION OR (E) IN ACCORDANCE WITH A REGISTRATION STATEMENT THAT HAS BEEN DECLARED
EFFECTIVE UNDER THE SECURITIES ACT AND THAT CONTINUES TO BE EFFECTIVE AT THE TIME OF SUCH TRANSFER; (2) PRIOR TO ANY SUCH TRANSFER (OTHER THAN A TRANSFER PURSUANT TO CLAUSE 1(E) ABOVE), IT WILL FURNISH TO THE COMPANY’S TRANSFER AGENT, SUCH
CERTIFICATIONS AND OTHER INFORMATION (OR, 

  

 15 








 
IN THE CASE OF A TRANSFER PURSUANT TO CLAUSE 1(D), SUCH LEGAL OPINIONS) AS THE COMPANY MAY REASONABLY REQUIRE TO CONFIRM THAT SUCH TRANSFER IS BEING MADE
PURSUANT TO AN EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT; AND (3) IT WILL DELIVER TO EACH PERSON TO WHOM THE COMMON STOCK EVIDENCED HEREBY IS TRANSFERRED (OTHER THAN A TRANSFER
PURSUANT TO CLAUSE 1(E) ABOVE) A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. THIS LEGEND WILL BE REMOVED UPON THE EARLIER OF THE TRANSFER OF THE COMMON STOCK EVIDENCED HEREBY PURSUANT TO CLAUSE 1(C) OR 1(E) ABOVE OR THE EXPIRATION OF TWO
YEARS FROM THE ORIGINAL ISSUANCE OF THE SECURITY UPON THE CONVERSION OR EXCHANGE OF WHICH THE COMMON STOCK EVIDENCED HEREBY WAS ISSUED. 
 Any such Common Stock as to which such restrictions on transfer shall have expired or terminated in accordance with their terms may, upon surrender of the certificates representing such shares of Common Stock for exchange in accordance with
the procedures of the transfer agent for the Common Stock, be exchanged for a new certificate or certificates for a like aggregate number of shares of Common Stock, which shall not bear the restrictive legend required by this Section 3.04(c).

 (d) Any Security or Common Stock issued upon the conversion or exchange of a Security that, prior to the expiration of the
holding period applicable to sales thereof under Rule 144(k) under the Securities Act (or any successor provision), is purchased or owned by the Company or any Affiliate thereof may not be resold by the Company or such Affiliate unless registered
under the Securities Act or resold pursuant to an exemption from the registration requirements of the Securities Act in a transaction that results in such Securities or Common Stock, as the case may be, no longer being “restricted
securities” (as defined under Rule 144). 
 (e) Notwithstanding any provision of Section 3.04 to the contrary, in
the event Rule 144(k) as promulgated under the Securities Act (or any successor rule) is amended to change the two-year period under Rule 144(k) (or the corresponding period under any successor rule), from and after receipt by the Trustee of the
Officers’ Certificate and Opinion of Counsel provided for in this Section 3.04(e), (i) each reference in Section 3.04(b) to “two years” and in the restrictive legend set forth in such paragraph to “TWO YEARS”
shall be deemed for all purposes hereof to be references to such changed period, (ii) each reference in Section 3.04(c) to “two years” and in the restrictive legend set forth in such paragraph to “TWO YEARS” shall be
deemed for all purposes hereof to be references to such changed period and (iii) all corresponding references in the Securities and the restrictive legends thereon shall be deemed for all purposes hereof to be references to such changed period,
provided that such changes shall not become effective if they are otherwise prohibited by, or would otherwise cause a violation of, the then-applicable federal securities laws. As soon as practicable after the Company has knowledge of the
effectiveness of any such amendment to change the two-year period under Rule 144(k) (or the corresponding period under any successor rule), unless such changes would otherwise be prohibited by, or would otherwise cause a violation of, the
then-applicable federal securities law, the Company shall provide to the Trustee an Officers’ Certificate and Opinion of Counsel informing the Trustee of the effectiveness of such amendment and the effectiveness of the foregoing changes to
Sections 3.04(b) and 3.04(c) and the Securities. The provisions of this Section 3.04(e) shall not be effective until such time as the Opinion of Counsel and Officers’ Certificate have been received by the Trustee hereunder. This
Section 3.04(e) shall apply to successive amendments to Rule 144(k) (or any successor rule) changing the holding period thereunder. 
 SECTION 3.05. Mutilated, Destroyed, Lost and Stolen Securities. If any mutilated Security is surrendered to the Trustee or the Company, together with such security or indemnity as may be required by the Company or the
Trustee to save each of them or any agent of either of them harmless, the Company shall, at the relevant Holder’s expense, execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of the same principal amount,
containing identical terms and provisions and bearing a number not contemporaneously outstanding. 
  

 16 








 If there shall be delivered to the Company and to the Trustee (i) evidence to their satisfaction of
the destruction, loss or theft of any Security and (ii) such security or indemnity as may be required by them to save each of them and any agent of either 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, at the relevant Holder’s expense, shall execute, and upon the Company’s request the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen
Security, a new Security of the same principal amount, containing identical terms and provisions and bearing a number not contemporaneously outstanding, appertaining to such destroyed, lost or stolen Security. 
 Notwithstanding the provisions of the previous two paragraphs, in case any such mutilated, destroyed, lost or stolen Security has become or is about to
become due and payable, the Company in its discretion may, instead of issuing a new Security, pay such Security. 
 Upon the issuance of any
new Security under this Section, 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 in lieu of any mutilated, destroyed, lost or stolen Security,
shall constitute an original additional contractual obligation of the Company, whether or not the mutilated, destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture
equally and proportionately with any and all other Securities duly issued hereunder. 
 The provisions of this Section 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 3.06. Payment of Interest; Interest Rights Preserved. Interest on any Security (including any Liquidated Damages) that is payable, and is punctually paid or duly provided for, on any Interest
Payment Date shall be paid to the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest at the office or agency of the Company maintained for
such purpose pursuant to Section 9.02; provided, however, that each installment of interest (including any Liquidated Damages) on any Security may at the Company’s option be paid by (i) mailing a check for such interest, payable to or
upon the written order of the Person entitled thereto pursuant to Section 3.07, to the address of such Person as it appears on the Security Register or (ii) if the Trustee shall have received written bank wire instructions prior to the
Regular Record Date for such payment, transfer to an account maintained by the payee located inside the United States; provided, however, that payments to DTC shall be made by wire transfer of immediately available funds to the account of DTC or its
nominee. The term “Regular Record Date” with respect to any Interest Payment Date shall mean the March 15 or September 15 preceding March 31 or September 30, respectively. 
 Any interest (including any Liquidated Damages) on any Security that is payable, but is not punctually paid or duly provided for, on any Interest Payment
Date (herein called “Defaulted Interest”) shall forthwith cease to be payable to the registered Holder thereof on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the
Company, at its election in each case, as provided in clause 3.06(a) or 3.06(b) below: 
 (a) The Company may elect to make
payment of any Defaulted Interest to the Persons in whose names the Securities (or their respective Predecessor Securities) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be
fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security and the date of the proposed payment (which shall not be less than 30 days after such notice is
received by the Trustee) and at the same time the Company shall deposit with the Trustee an amount of 

  

 17 








 
money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such
deposit on or prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this clause provided. Thereupon the Company shall fix a Special Record
Date for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment. The Company shall promptly notify the Trustee of such Special Record Date and, in the name and
at the expense of the Company, the Trustee shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to each Holder of Securities at his address as it
appears in the Security Register not less than 10 days prior to such Special Record Date. The Trustee may, in its discretion, in the name and at the expense of the Company, cause a similar notice to be published at least once in an Authorized
Newspaper in each Place of Payment, but such publications shall not be a condition precedent to the establishment of such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been
mailed as aforesaid, such Defaulted Interest shall be paid to the Persons in whose names the Securities (or their respective Predecessor Securities) are registered at the close of business on such Special Record Date and shall no longer be payable
pursuant to the following clause (b). 
 (b) The Company may make payment of any Defaulted Interest on the Securities in
any other lawful manner not inconsistent with the requirements of any securities exchange on which such Securities may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the
proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee. 
 Subject to the foregoing
provisions of this Section, each Security delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by
such other Security. 
 SECTION 3.07. 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 (and premium, if any),
and (subject to Sections 3.04 and 3.06) interest on, such Security and for all other purposes whatsoever, whether or not such Security is overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be
affected by notice to the contrary. 
 None of the Company, the Trustee, any Paying Agent or the Security Registrar shall have any
responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a Security in global form or for maintaining, supervising or reviewing any records relating to such beneficial
ownership interests. 
 Notwithstanding the foregoing, with respect to any global Security, 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 any depositary, as a Holder, with respect to such global Security or impair, as between such depositary
and owners of beneficial interests in such global Security, the operation of customary practices governing the exercise of the rights of such depositary (or its nominee) as a Holder of such global Security. 
 SECTION 3.08. Cancellation. All Securities surrendered for payment, redemption, repayment at the option of the Holder or registration of
transfer or exchange shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee, and any such Securities surrendered directly to the Trustee for any such purpose shall be promptly canceled by it. The Company may at any
time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder that the Company may have acquired in any manner whatsoever, and may deliver to the Trustee (or to any other Person for delivery to the
Trustee) for cancellation 

  

 18 








 
any Securities previously authenticated hereunder that the Company has not issued and sold, and all Securities so delivered shall be promptly canceled by the
Trustee. If the Company shall so acquire any of the Securities, however, such acquisition shall not operate as a redemption or satisfaction of the indebtedness represented by such Securities unless and until the same are surrendered to the Trustee
for cancellation. No Securities shall be authenticated in lieu of or in exchange for any Securities canceled as provided in this Section, except as expressly permitted by this Indenture. Canceled Securities held by the Trustee shall be destroyed by
the Trustee and the Trustee shall deliver a certificate of such destruction to the Company, unless by a Company Order the Company directs their return to it. 
 SECTION 3.09. Computation of Interest. Interest (including any Liquidated Damages) on the Securities shall be computed on the basis of a 360-day year consisting of twelve 30-day months. 
 SECTION 3.10. CUSIP Numbers. The Company in issuing the Securities shall use “CUSIP” numbers, and the Trustee shall use CUSIP
numbers in notices of redemption as a convenience to Holders; provided however, 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 shall promptly notify the
Trustee of any change in the CUSIP numbers applicable to the Securities. 
 ARTICLE 4

 (f) default in the performance, or breach, of any covenant or warranty of the Company in this Indenture with respect to any Security

or certified mail, to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in principal amount of the Outstanding Securities a written notice specifying such default or breach and requiring it to be remedied
and stating that such notice is a “Notice of Default” hereunder; or 
  

 19 








 (g) a default under any bonds, debentures, notes or other evidences of indebtedness for
money borrowed of the Company or under any mortgages, indentures or instruments under which there may be issued or by which there may be secured or evidenced any indebtedness for money borrowed by the Company, whether such indebtedness now exists or
shall hereafter be created, which indebtedness, individually or in the aggregate, has a principal amount outstanding in excess of $10,000,000, which default shall have resulted in such indebtedness becoming or being declared due and payable prior to
the date on which it would otherwise have become due and payable, without such indebtedness having been discharged, or such acceleration having been rescinded or annulled, within a period of 60 days after there shall have been given, by registered
or certified mail, to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in principal amount of the Securities then Outstanding, a written notice specifying such default and requiring the Company to cause
such indebtedness to be discharged or cause such acceleration to be rescinded or annulled and stating that such notice is a “Notice of Default” hereunder (unless such default has been cured or waived); or

determined in accordance with GAAP, consistently applied or shall not fairly present the Company’s results of operation for any such quarter. 
 As used in this Section 4.01 only, the term “Bankruptcy Law” means title 11, U.S. Code or any similar Federal or State law for the relief of debtors; and the term “Custodian” means any receiver,
trustee, assignee, liquidator or other similar official under any Bankruptcy Law. 
 SECTION 4.02. Acceleration of Maturity;
Rescission and Annulment. Subject to the immediately succeeding paragraph, if an Event of Default with respect to Securities at the time Outstanding occurs and is continuing, then and in every such case the Trustee, or the Holders of not
less than 25% in principal amount of the Outstanding Securities, may declare the principal of all the Securities, and accrued interest thereon to the date of such declaration, to be due and payable immediately, by a notice in writing to the Company
(and to the Trustee if given by the Holders), and upon any such declaration such principal shall become immediately due and payable. If an Event of Default specified in Section 4.01(h) or Section 4.01(i) occurs, the principal of, and
accrued interest on, all the Securities shall automatically, and without any declaration or other action on the part of the Trustee or any Holder, become immediately due and payable. 
  

 20 








 At any time after such a declaration of acceleration with respect to the Securities has been made and
before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter provided in this Article, the Holders of a majority in principal amount of the Outstanding Securities, by written notice to the Company and the
Trustee, may rescind and annul such declaration and its consequences if: 
 (a) the Company has paid or deposited with the
Trustee a sum sufficient to pay: 
 (i) all overdue installments of interest on all Outstanding Securities, 
 (ii) the principal of (and premium, if any, on) any Outstanding Securities that have become due otherwise than by reason of such
declaration of acceleration and interest thereon at the rate or rates borne by or provided for in such Securities, 
 (iii) to
the extent that payment of such interest is lawful, interest upon overdue installments of interest at the rate or rates borne by or provided for in such Securities, and 
 (iv) all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel; and 
 (b) all Events of Default with respect to the Securities, other than the nonpayment of
the principal of (or premium, if any) or interest on Securities which have become due solely by reason of such declaration of acceleration, have been cured or waived as provided in Section 4.13. 
 No such rescission shall affect any subsequent Default or Event of Default or impair any right in respect thereof. 
 SECTION 4.03. Collection of Indebtedness and Suits for Enforcement by Trustee. The Company covenants that if: 
 (a) default is made in the payment of any installment of interest (including any Liquidated Damages) on any Security when such interest
becomes due and payable and such default continues for a period of 30 days, or 
 (b) default is made in the payment of the
principal of (or premium, if any, on) any Security at its Maturity, 
 then the Company shall, upon demand of the Trustee, pay to the Trustee,
for the benefit of the Holders of such Securities, the whole amount then due and payable on such Securities for principal (and premium, if any) and interest (including any Liquidated Damages), with interest upon any overdue principal (and premium,
if any) and, to the extent that payment of such interest shall be legally enforceable, upon any overdue installments of interest (including any Liquidated Damages), at the rate or rates borne by or provided for in such Securities, and, in addition
thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. 
 If the Company fails to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, and may prosecute such proceeding to judgment or final decree, and may enforce the same against the Company or any other obligor upon such Securities under a supplemental
indenture entered into in accordance herewith and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other such obligor upon such Securities, wherever situated. 
 If an Event of Default occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the
Holders of Securities by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the
exercise of any power granted herein, or to enforce any other proper remedy. 
  

 21 








 SECTION 4.04. 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 under a supplemental indenture entered into in
accordance herewith or the property of the Company or of such other obligor or the Company’s, or any such other obligor’s, creditors, the Trustee (irrespective of whether the principal of the Securities shall then be due and payable as
therein expressed or by acceleration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the payment of overdue principal, premium, if any, or interest) shall be entitled and empowered, by intervention
in such proceeding or otherwise: 
 (a) to file and prove a claim for the whole amount, or such lesser amount as may be
provided for in the Securities, of principal (and premium, if any) and interest, owing and unpaid in respect of the Securities 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) 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 other similar official) in any such judicial proceeding is hereby directed
by each Holder to make such payments to the Trustee, and in the event that the Trustee shall request or consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation,
expenses, disbursements and advances of the Trustee and any predecessor Trustee, their agents and counsel, and any other amounts due the Trustee or any predecessor Trustee under Section 5.07. 
 Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder of a Security,
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 of a Security in any such proceeding; provided
however, that the Trustee may, on behalf of the Holders, vote for the election of a trustee in bankruptcy or similar official and be a member of a creditors’ or other similar committee. 
 SECTION 4.05. Trustee May Enforce Claims Without Possession of Securities. All rights of action and claims under this Indenture or any
of the Securities may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its
own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of
the Holders of the Securities in respect of which such judgment has been recovered. 
 SECTION 4.06. Application of Money
Collected. Any money collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal (or premium, if
any) or interest, upon presentation of the Securities, or both, as the case may be, and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid: 
 FIRST: To the payment of all amounts due the Trustee and any predecessor Trustee under Section 5.07; 
 SECOND: To the payment of the amounts then due and unpaid upon the Securities for principal (and premium, if any) and interest (including Liquidated
Damages, if any) payable, and any other amounts due and payable under this Indenture or under the Securities (including with respect to the Make-Whole Premium, if any), in respect of which or for the benefit of which such money has been collected,
ratably, without preference or 

  

 22 








 
priority of any kind, according to the aggregate amounts due and payable on such Securities for principal (and premium, if any), interest (including
Liquidated Damages, if any) and any Make-Whole Premium, respectively; and 
 THIRD: To the payment of the remainder, if any, to the Company.

 SECTION 4.07. Limitation on Suits. No Holder of any Security shall have any right to institute any proceeding, judicial
or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless: 
 (a) such Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to the Securities; 
 (b) the Holders of not less than 25% in principal amount of the Outstanding Securities shall have made written request to the Trustee to
institute proceedings in respect of such Event of Default in its own name as Trustee hereunder; 
 (c) such Holder or Holders
have offered to the Trustee security or indemnity reasonably satisfactory to the Trustee against the costs, expenses and liabilities to be incurred in compliance with such request; 
 (d) the Trustee for 60 days after its receipt of such notice, request and offer of security or indemnity has failed to institute any such
proceeding; and 
 (e) no direction inconsistent with such written request has been given to the Trustee during such 60-day
period by the Holders of a majority in principal amount of the Outstanding Securities; 
 it being understood and intended that no one or more
of such Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other of such Holders, or to obtain or to seek to obtain priority or
preference over any other of such Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all such Holders. 
 SECTION 4.08. Unconditional Right of Holders to Receive Principal, Premium, If Any, and Interest. Notwithstanding any other provision in
this Indenture, the Holder of any Security shall have the right, which is absolute and unconditional, to receive payment of the principal of, and premium, if any, including the Redemption Prices, the Repurchase Price pursuant to Article 11 and
(subject to Sections 3.04 and 3.06) interest (including Liquidated Damages, if any) on such Security on the respective due dates expressed in such Security (or, in the case of redemption or repurchase, on the Redemption Date or Repurchase Date,
as the case may be) and to convert such Security in accordance with the provisions of this Indenture and to institute suit for the enforcement of any such payment and right to convert, and such rights shall not be impaired or adversely affected
without the consent of such Holder. 
 SECTION 4.09. Restoration of Rights and Remedies. If the Trustee or any Holder of a
Security has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every
such case, the Company, the Trustee and the Holders of Securities shall, subject to any determination in such proceeding, be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the
Trustee and the Holders shall continue as though no such proceeding had been instituted. 
 SECTION 4.10. Rights and Remedies
Cumulative. Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in the last paragraph of Section 3.05, no right or remedy herein conferred upon or reserved to the
Trustee or to the Holders of Securities is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be 

  

 23 








 
cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. 
 SECTION 4.11. Delay or Omission Not Waiver. No delay or omission of the Trustee or of any Holder of any Security to exercise any right or remedy accruing upon any Event of Default shall impair any
such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may
be deemed expedient, by the Trustee or by the Holders of Securities, as the case may be. 
 SECTION 4.12. Control by Holders of
Securities. The Holders of not less than a majority in principal amount of the Outstanding Securities shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or
exercising any trust or power conferred on the Trustee with respect to the Securities, provided that: 
 (a) such direction
shall not be in conflict with any rule of law or with this Indenture, 
 (b) the Trustee may take any other action deemed
proper by the Trustee that is not inconsistent with such direction, and 
 (c) the Trustee need not take any action that might
involve it in personal liability or be unduly prejudicial to the Holders of Securities not joining therein. 
 SECTION 4.13. Waiver
of Past Defaults. The Holders of not less than a majority in principal amount of the Outstanding Securities may on behalf of the Holders of all the Securities waive any past Default or Event of Default hereunder with respect to such
Securities and its consequences, except a Default or Event of Default: 
 (a) in the payment of the principal of (or premium,
if any) or interest (including Liquidated Damages) on any Security, 
 (b) in respect of the conversion by the Company of any
Security into Common Stock, 
 (c) in the payment of the Redemption Price pursuant to Article 10, 
 (d) in the payment of the Repurchase Price pursuant to Article 11, 
 (e) in the payment of the Additional Interest Payment, if any, pursuant to Article 12, 
 (f) in the payment of the Make-Whole Premium, if any, pursuant to Article 12, 
 (g) in respect of a covenant or provision hereof that under Article 8 cannot be modified or amended without the consent of the Holder
of each Outstanding Security affected; or 
 (h) in respect of a covenant or provision hereof for the personal protection or
benefit of the Trustee, without the consent of the Trustee. 
 Upon any such waiver, such Default or Event of Default shall cease to exist,
and any Event of Default arising from any such Default shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent
thereon. 
 SECTION 4.14. Waiver of Usury, Stay or Extension Laws. The Company covenants (to the extent that it may lawfully
do so) that it shall not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any usury, stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the
covenants or the performance of this Indenture; and the Company (to the extent that 

  

 24 








 
it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it shall 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. 
 SECTION 4.15. Undertaking for Costs. All parties to this Indenture agree, and each Holder of any Security by his acceptance thereof shall be deemed to have agreed, that any court may in its discretion
require, 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, the filing by any party litigant in such suit of an undertaking to pay the
costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in such suit having due regard to the merits and good faith of the claims or defenses made
by such party litigant; but the provisions of this Section shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in principal amount of the
Outstanding Securities, or to any suit instituted by any Holder for the enforcement of the payment of the principal of (or premium, if any) or interest on any Security on or after the respective Stated Maturities expressed in such Security (or, in
the case of redemption or repurchase, on or after the Redemption Date or the Repurchase Date, respectively), or the right to convert any Security in accordance with Article 12. 
 ARTICLE 5 
 THE TRUSTEE 
 SECTION 5.01. General. The Trustee, prior to the occurrence of an Event of Default known to a Responsible Officer of the Trustee and
after the curing of all Events of Default that may have occurred, undertakes to perform such duties and only such duties as are specifically set forth in this Indenture. In case an Event of Default has occurred (that has not been cured or waived)
and is known to a Responsible Officer of the Trustee, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent man would exercise or use under
the circumstances in the conduct of his own affairs. 
 No provision of this Indenture shall be construed to relieve the Trustee from
liability for its own negligent action, its own negligent failure to act, its own willful misconduct, its own recklessness or its own bad faith. 
 SECTION 5.02. Certain Rights of Trustee. Subject to TIA Sections 315(a) through (d): 
 (a) the
Trustee may rely, and shall be protected in acting or refraining from acting, upon any resolution, certificate, statement, instrument, facsimile transmission, 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, made or presented by the proper person, and may accept and rely upon the same as conclusive evidence of the truth and accuracy of the
statements and opinions contained therein. The Trustee need not investigate any fact or matter stated in any such document; 
 (b) before the Trustee acts or refrains from acting, it may require an Officers’ Certificate or an Opinion of Counsel, which shall conform to Section 1.03. The Trustee shall not be liable for any action it takes or omits to take
in good faith in reliance on such certificate or opinion; 
 (c) the Trustee may consult with counsel, and the written advice
of such counsel shall be full and complete authorization and protection with respect to any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon, and may act through its attorneys and agents and shall not be
responsible for the misconduct or negligence of any attorney or agent appointed with due care; 
 (d) the Trustee shall be
under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders, unless such Holders shall have offered to the Trustee reasonable security or indemnity against the costs,
expenses and liabilities that might be incurred by it in complying with such request or direction; 
  

 25 








 (e) the Trustee shall not be liable for any action it takes or omits to take in good
faith that it believes to be authorized or within its rights or powers or for any action it takes or omits to take in accordance with the written direction of the holders of a majority in principal amount of the Outstanding Securities relating to
the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture; 
 (f) whenever in the administration of this Indenture the Trustee shall deem it desirable that a matter be proved or established prior to
taking, suffering or omitting any action hereunder, the Trustee (unless other evidence be herein specifically prescribed) may, in the absence of bad faith on its part, rely upon an Officers’ Certificate; 
 (g) 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; 
 (h) the Trustee shall not be required to take notice or be deemed to have notice of any Default or Event of Default unless the Trustee be
specifically notified of such Default or Event of Default in writing by the Company or any Holder, and in the absence of such notice the Trustee may conclusively assume that there is no Default or event of Default; provided that if the
Trustee is acting as Paying Agent, the Trustee shall be required to take and be deemed to have notice of its failure to receive payments of interest or principal hereunder; 
 (i) the Trustee shall have no responsibility with respect to any information in any offering memorandum or other disclosure material
distributed with respect to the Securities, and the Trustee shall have no responsibility for compliance with securities laws in connection with the issuance and sale, resale, transfer or exchange of the Securities; 
 (j) in the event the Trustee shall receive inconsistent or conflicting requests and security or indemnity from two or more groups of
Holders, each representing at least 25% (but less than 50%) of the aggregate principal amount of the Securities then Outstanding, the Trustee shall act in accordance with instructions received by the Holders of the greater percentage thereof;

 (k) except as otherwise expressly provided by the provisions of this Indenture, the Trustee shall not be obligated, and may
not be required to give or furnish any notice, demand, report, request, reply, statement, advice or opinion to any Holder or to the Company or any other Person, and the Trustee shall not incur any liability for its failure or refusal to give or
furnish the same unless obligated or required to do so by the express provisions hereof; 
 (l) the Trustee shall not be
required to give any bond or surety with respect to the performance of its duties or the exercise of its powers under this Indenture; and 
 (m) any permissive power or authority granted to the Trustee shall not be construed to be a duty. 
 SECTION 5.03. Individual Rights of Trustee. The Trustee, any Paying Agent, Security Registrar or any other agent of the Company, in its individual or any other capacity, may become the owner or pledgee of Securities and may
otherwise deal with the Company, its Subsidiaries or its Affiliates with the same rights it would have if it were not the Trustee, Paying Agent, Security Registrar or such other agent. Any registrar, co-registrar, paying agent, conversion agent or
authenticating agent may do the same with like rights. However, upon qualification of this Indenture under the TIA, the Trustee shall be subject to TIA Sections 310(b) and 311. 
 SECTION 5.04. Trustee’s Disclaimer. The Trustee (i) makes no representation as to the validity or adequacy of this Indenture,
the Securities or the offering documents relating to the Securities, (ii) shall not be accountable for the Company’s use or application of the proceeds from the Securities and (iii) shall not be responsible for any statement in the
Securities other than its certificate of authentication. 
  

 26 








 SECTION 5.05. Notice of Default. If any Event of Default occurs and is continuing and if
a Responsible Officer of the Trustee has actual knowledge of such Event of Default, the Trustee shall mail to each holder in the manner and to the extent provided in TIA Section 313(c) notice of the Event of Default within 90 days after it
occurs, unless such Event of Default has been cured or waived; provided, however, that, except in the case of a Default in the payment of the principal of (or premium, if any) or interest on any Security, the Trustee shall be protected in
withholding such notice if and so long as Responsible Officers of the Trustee in good faith determine that the withholding of such notice is in the interests of the Holders of the Securities. 
 SECTION 5.06. Conflicting Interests of Trustee. If the Trustee has or shall acquire a conflicting interest within the meaning of the
TIA, the Trustee shall either eliminate such interest or resign, to the extent and in the manner provided by, and subject to the provisions of, the TIA and this Indenture. 
 SECTION 5.07. Compensation and Indemnity. The Company shall pay to the Trustee such compensation as shall be agreed upon in writing for
its services. The compensation of the Trustee shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee upon request for all reasonable out-of-pocket expenses, disbursements and
advances incurred or made by the Trustee in accordance with this Indenture. Such expenses shall include the reasonable compensation, expenses, disbursements and advances of the Trustee’s agents and counsel. 
 The Company shall indemnify and hold harmless the Trustee and its directors, agents and employees (including officers) (collectively the
“Indemnitees”) against any and all losses, liabilities, obligations, damages, penalties, fines, judgments, actions, suits, proceedings, reasonable costs and expenses (including reasonable fees and disbursements of counsel) of any
kind whatsoever that may be incurred by or imposed on the Indemnitees or any of them arising out of or in connection with the acceptance or administration of the Trustee’s duties under this Indenture; provided, however, that the Company
need not reimburse any expense or indemnify against any loss, obligation, damage, penalty, fine, judgment, action, suit, proceeding, reasonable cost or expense (including reasonable fees and disbursements of counsel) of any kind whatsoever that may
be incurred by Indemnitees or any of them which results from the negligence or willful misconduct of the Indemnitees or any of them. The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee
to so notify the Company shall not relieve the Company of its obligations hereunder, unless the Company is materially prejudiced thereby. The Company shall defend the claim, and the Trustee shall cooperate in the defense. Unless otherwise set forth
herein, the Indemnitees or any of them, may have separate counsel and the Company shall pay the reasonable fees and expenses of such counsel. The Company need not pay for any settlement made without its consent, which consent shall not be
unreasonably withheld. The provisions of this Section 5.07 shall survive the termination of this Indenture and the resignation or removal of the Trustee for any reason, including any termination under any bankruptcy law. 
 To secure the Company’s payment obligations in this Section 5.07, the Trustee shall have a lien prior to the Securities on all money or
property held or collected by the Trustee, in its capacity as Trustee, except money or property held in trust to pay principal of, premium, if any, and interest on particular Securities. 
 If the Trustee incurs expenses or renders services after the occurrence of an Event of Default specified in Section 4.01(h) or Section 4.01(i),
such expenses, and the compensation due to the Trustee for such services, are intended to constitute expenses of administration under Title 11 of the United States Bankruptcy Code or any applicable federal or state law for the relief of debtors.

 SECTION 5.08. Replacement of Trustee. A resignation or removal of the Trustee and appointment of a successor Trustee
shall become effective only upon the successor Trustee’s acceptance of appointment as provided in this Section 5.08. 
 The Trustee
may resign at any time by so notifying the Company in writing at least thirty days prior to the date of the proposed resignation. The Holders of a majority in principal amount of the Outstanding Securities 

  

 27 








 
may at any time, by written notice to the Trustee and the Company, remove the Trustee and, with the prior consent of the Company, appoint a successor
Trustee. The Company may remove the Trustee if: (i) the Trustee is no longer eligible under Section 5.10; (ii) the Trustee is adjudged a bankrupt or an insolvent; (iii) a receiver or other public officer takes charge of the
Trustee or its property; or (iv) the Trustee becomes incapable of acting. 
 If the Trustee is removed without the concurrent
appointment by the Holders of a successor Trustee, if the Trustee resigns, or if a vacancy exists in the office of Trustee for any other reason, the Company shall promptly appoint a successor Trustee. If no successor Trustee has delivered its
written acceptance required by the next succeeding paragraph of this Section 5.08 within thirty days after the retiring Trustee delivers notice of its resignation or is removed, or after the occurrence of a vacancy in the office of Trustee for
any other reason, the retiring Trustee, the Company or the Holders of a majority in principal amount of the Outstanding Securities may petition any court of competent jurisdiction for the appointment of a successor Trustee. 
 A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Immediately after the delivery of
such written acceptance, subject to the lien provided in Section 5.07, (i) the retiring Trustee shall transfer all property held by it as Trustee to the successor Trustee, (ii) the resignation or removal of the retiring Trustee shall
become effective and (iii) the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. A successor Trustee shall mail notice of its succession to each Holder. 
 If the Trustee is no longer eligible under Section 5.10, any Holder who satisfies the requirements of TIA Section 310(b) may petition any court
of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 
 The Company shall give notice of any
resignation and any removal of the Trustee and each appointment of a successor Trustee to all Holders. Each notice shall include the name of the successor Trustee and the address of its Corporate Trust Office. 
 Notwithstanding replacement of the Trustee pursuant to this Section 5.08, the Company’s obligations under Section 5.07 shall continue for
the benefit of the retiring Trustee. 
 SECTION 5.09. Successor Trustee by Merger, Etc. If the Trustee consolidates with,
merges or converts into, or transfers all or substantially all of its corporate trust business (including the administration of this Indenture) to, another corporation or national banking association, the resulting, surviving or transferee
corporation or national banking association, without any further act, shall be the successor Trustee with the same effect as if the successor Trustee had been named as the Trustee herein. 
 SECTION 5.10. Eligibility. This Indenture shall always have a Trustee who satisfies the requirements of TIA Section 310(a)(1). The
Trustee (or the bank holding company to which the Trustee is a member) shall have a combined capital and surplus of at least $25 million as set forth in its most recent published annual report of condition. 
 SECTION 5.11. Money Held in Trust. Subject to the provisions of Section 9.03, all monies received by the Trustee shall, until used
or applied as herein provided, be held in trust for the purposes for which they were received. The Trustee shall not be liable for interest on any money received by it except as the Trustee may agree with the Company. Money held in trust by the
Trustee need not be segregated from other funds except to the extent required by law. 
 SECTION 5.12. Preferential Collection of
Claims. If and when the Trustee shall be or become a creditor of the Company (or any other obligor upon the Securities under a supplemental indenture entered into in accordance herewith), the Trustee shall be subject to the provisions of
the Trust Indenture Act regarding the collection of the claims against the Company (or any such other obligor). 
  

 28 








 SECTION 5.13. Trustee’s Application for Instructions from the Company; Liquidated
Damages. (a) Any application by the Trustee for written instructions from the Company (other than with regard to any action proposed to be taken or omitted to be taken by the Trustee that affects the rights of the Holders) may, at the option of
the Trustee, set forth in writing any action proposed to be taken or omitted by the Trustee under this Indenture and the date on and/or after which such action shall be taken or such omission shall be effective. The Trustee shall not be liable for
any action taken by, or omission of, the Trustee in accordance with a proposal included in such application on or after the date specified in such application (which date shall not be less than ten Business Days after the date any officer of the
Company actually receives such application, unless any such officer shall have consented in writing to any earlier date) unless prior to taking any such action (or the effective date in the case of an omission), the Trustee shall have received
written instructions in response to such application specifying the action to be taken or omitted. 
 (b) If Liquidated
Damages are payable to Holders pursuant to the terms of the Registration Rights Agreement, the Company shall deliver to the Trustee a certificate to that effect stating (i) the amount of Liquidated Damages that is payable and (ii) the date
on which such amount of Liquidated Damages is payable. Unless and until a Responsible Officer of the Trustee receives at the Corporate Trust Office such a certificate, the Trustee may assume without inquiry that no Liquidated Damages are payable.
Upon receipt of a Company Request together with a sum sufficient to pay such Liquidated Damages so becoming due, the Trustee shall pay such Liquidated Damages to the Holders in the same manner as interest on the Securities. If the Company has paid
Liquidated Damages directly to the Persons entitled to them, the Company shall deliver to the Trustee a certificate setting forth the particulars of such payment. 
 ARTICLE 6 
 HOLDERS’ LISTS AND
REPORTS BY TRUSTEE AND COMPANY 
 SECTION 6.01.
Disclosure of Names and Addresses of Holders. Every Holder of Securities, by receiving and holding the same, agrees with the Company and the Trustee that none of the Company, the Trustee, any Paying Agent or any Security Registrar, shall

to Sections 13(a) or 13(b) or Section 15(d) of the Exchange Act; or, if the Company is not required to file information, documents or reports pursuant to any of such Sections, then it shall file with the Trustee, in accordance with rules

 (i) semiannually, not later than 10 days after the Regular Record Date for the payment of
interest on the Securities, a list, in such form as the Trustee may reasonably require, of the names and addresses of the Holders as of such Regular Record Date; and 
 (ii) at such other times as the Trustee may request in writing, within 30 days after the receipt by the Company of any such request, a

 provided, however,
that, so long as the Trustee is the Security Registrar, no such list shall be required to be furnished.

Sales, Leases and Conveyances Permitted Subject to Certain Conditions. The Company may consolidate with, or sell, lease, transfer, convey or otherwise dispose of all or substantially all of its assets to, or merge with or into any other
Person, provided however, that in any such case, (1) either the Company shall be the continuing corporation, or the Person (if other than the Company) formed by such consolidation or into which the Company is merged or the Person (if other than

Subsidiary), which, if such assets were owned by the Company, would constitute all or substantially all of the properties and assets of the Company, shall be deemed to be the transfer of all or substantially all of the properties and assets of the
Company. 
  

 30 








 SECTION 7.02. Rights and Duties of Successor Corporation. In case of any such
consolidation, merger, sale, lease, conveyance or other disposition and upon any such assumption by the successor Person, such successor Person shall succeed to and be substituted for the Company, with the same effect as if it had been named herein
as the party of the first part, and the predecessor corporation, except in the event of a lease, shall be relieved of any further obligation under this Indenture and the Securities. Such successor Person thereupon may cause to be signed, and may
issue either in its own name or in the name of the Company, any or all of the Securities issuable hereunder that theretofore shall not have been signed by the Company and delivered to the Trustee; and, upon the order of such successor Person,
instead of the Company, and subject to all the terms, conditions and limitations in this Indenture prescribed, the Trustee shall authenticate and shall deliver any Securities that previously shall have been signed and delivered by the officers of
the Company to the Trustee for authentication, and any Securities that such successor Person thereafter shall cause to be signed and delivered to the Trustee for that purpose. All the Securities so issued shall in all respects have the same legal
rank and benefit under this Indenture as the Securities theretofore or thereafter issued in accordance with the terms of this Indenture as though all of such Securities had been issued at the date of the execution hereof. 
 In case of any such consolidation, merger, sale, lease, conveyance or other disposition, such changes in phraseology and form (but not in substance) may

successor Person pursuant to this Article 7 constitutes the legal, valid and binding obligation of such successor Person, subject to customary exceptions. 
 ARTICLE 8 
 SUPPLEMENTAL INDENTURES 
 SECTION 8.01. Supplemental Indentures Without Consent of Holders. Without the consent of any Holders of Securities, the Company, when
authorized by or pursuant to a Board Resolution, and the Trustee, at any time and from time to time, may enter into one or more indentures supplemental hereto, in form satisfactory to the Trustee, for any of the following purposes:

of Default for the benefit of the Holders proposed by the Company in a Company Request and, in respect of any such additional Event of Default, such supplemental indenture may provide for a particular period of grace after default (which period may
be shorter or longer than that allowed in the case of other defaults) or may provide for an immediate enforcement upon such Event of Default, or may limit the remedies available to the Trustee upon such Event of Default or limit the right of the
Holders of a majority in aggregate principal amount of those Securities to which such additional Events of Default apply to waive such default, all as set forth in the Company Request; 
 (d) to evidence and provide for the acceptance of appointment hereunder by a successor Trustee and to add to or change any of the
provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee;

 (e) to cure any ambiguity or to correct or supplement any provision herein that may be
defective or inconsistent with any other provision herein; provided such provisions shall not adversely affect the interests of the Holders of Securities in any material respect; 
 (f) to make any change that does not adversely affect the rights of any holder of Securities or to surrender any right, power or option
conferred on the Company hereunder; or 
 (g) to make any change to comply with any requirement of the Commission in
connection with the qualification of the Indenture under TIA; or 
 (h) to provide for the issuance of uncertificated

 The Company and the Trustee may not enter into a supplemental indenture pursuant to this Section 8.01 if such supplemental indenture modifies in any
respect any Event of Default relating to any covenant in this Indenture in effect immediately prior to the time such supplemental indenture becomes effective. 
 SECTION 8.02. Supplemental Indentures with Consent of Holders. With the consent of the Holders of not less than a majority in principal amount of the Outstanding Securities affected by such
supplemental indenture, by Act of said Holders delivered to the Company and the Trustee, the Company, when authorized by or pursuant to a Board Resolution, and the Trustee may enter into an indenture or indentures supplemental hereto for the purpose
of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or of modifying in any manner the rights of the Holders; provided, however, that no such supplemental indenture shall, without the consent
of the Holder of each Outstanding Security affected thereby: 
 (a) reduce the principal amount, Repurchase Price or
Redemption Price with respect to any Security, or extend the Stated Maturity of any Security or alter the manner of payment or rate of interest on any Security or make any Security (including any Liquidated Damages or Redemption Price or Repurchase

 ARTICLE 9 
 COVENANTS 
 SECTION 9.01. Payment of Principal, Premium, If Any, and Interest. The Company covenants and agrees for the benefit of the Holders of
Securities that it shall duly and punctually pay the principal of (and premium, if any), interest on (including Liquidated Damages, if any), and the Repurchase Price, the Redemption Price, the Make-Whole Premium and the Additional Interest Payment
with respect to, the Securities in accordance with the terms of the Securities and this Indenture. At the option of the Company, all payments of principal with respect to any Security may be paid by check to the registered Holder of the Security or
other Person entitled thereto against surrender of such Security. The conversion of any Securities pursuant to Article 12 hereof and payment of the Additional Interest Payment by delivery of shares of Common Stock in accordance with
Article 10, together with the making of any cash payments required to be made in accordance with the terms of the Securities and this Indenture, shall satisfy the Company’s obligations under this Section 9.01 with respect to such
Securities. 
 SECTION 9.02. Maintenance of Office or Agency. The Company shall maintain a Place of Payment for the
Securities in the Borough of Manhattan, The City of New York, which shall be an office or agency where the Securities may be presented or surrendered for payment or conversion, exchange or redemption, where the Securities may be surrendered for
registration of transfer or exchange and where notices and demands to or upon the Company in respect of the Securities and this Indenture may be served. The Company initially designates U.S. Bank National Association, at 100 Wall Street, Suite 1600,
New York, N.Y. 10005 as such an office or agency of the Company, unless and until the Company shall designate and maintain some other office or agency for one or more of such purposes. The Company shall give prompt written notice to the Trustee of
the location, and any change in the location, of each such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations,
surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee, and the Company hereby appoints the Trustee its agent to receive all such presentations, surrenders, notices and demands. 
 The Company may from time to time designate one or more other offices or agencies (in or outside of The City of New York) where the Securities may be
presented or surrendered for any or all of such purposes, and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an
office or agency in accordance with the requirements set forth above for such purposes. The Company shall give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or
agency. 
  

 33 








 SECTION 9.03. Money for Securities Payments to Be Held in Trust. If the Company shall at
any time act as its own Paying Agent with respect to any Securities, it shall, on or before each due date of the principal of (and premium, if any), or interest on, the Securities, segregate and hold in trust for the benefit of the Persons entitled
thereto a sum sufficient to pay the principal (and premium, if any) or interest so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided, and shall promptly notify the Trustee of its action or failure
so to act. 
 Whenever the Company shall have one or more Paying Agents for the Securities, it shall, before each due date of the principal
of (and premium, if any), or interest on, the Securities, deposit with a Paying Agent a sum sufficient to pay the principal (and premium, if any) or interest, so becoming due, such sum to be held in trust for the benefit of the Persons entitled to
such principal, premium or interest and (unless such Paying Agent is the Trustee) the Company shall promptly notify the Trustee of its action or failure so to act. 
 The Company shall cause each Paying Agent other than the Trustee to execute and deliver to the Trustee an instrument pursuant to which such Paying Agent shall agree with the Trustee, subject to the provisions of this
Section, that such Paying Agent shall: 
 (a) hold all sums held by it for the payment of principal of (and premium, if any,)
or interest on the Securities, in trust for the benefit of the Persons entitled thereto, until such sums shall be paid to such Persons or otherwise disposed of as herein provided; 
 (b) give the Trustee notice of any default by the Company (or any other obligor upon the Securities under a supplemental indenture entered
into in accordance herewith) in the making of any such payment of principal (and premium, if any) or interest; and 
 (c) at
any time during the continuance of any such default, upon the written request of the Trustee, forthwith pay to the Trustee all sums so held in trust by such Paying Agent. 
 The Company may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay, to the Trustee all sums
held in trust by the Company or such Paying Agent, such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by the Company or such Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such
Paying Agent shall be released from all further liability with respect to such sums. 
 Any money deposited with the Trustee or any Paying
Agent, or then held by the Company, in trust for the payment of the principal of (and premium, if any) or interest on any Security and remaining unclaimed for two years after such principal (and premium, if any) or interest has become due and
payable shall be paid to the Company upon Company Request or (if then held by the Company) shall be discharged from such trust; and the Holder of such Security shall thereafter, as an unsecured general creditor, look only to the Company for payment
of such principal of (and premium, if any) or interest on any Security, without interest thereon, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall
thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in an Authorized Newspaper, notice that such money
remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication, any unclaimed balance of such money then remaining shall be repaid to the Company. 
 SECTION 9.04. Existence. Subject to Article 7, the Company shall do or cause to be done all things necessary to preserve and keep
in full force and effect the corporate existence of the Company and its Subsidiaries, and their respective rights (charter and statutory) and franchises, except to the extent that the Board of Directors shall determine that the failure to do so
would not have a material adverse effect on the business, 

  

 34 








 
assets, financial condition or results of operation of the Company (a “Material Adverse Effect”); provided, however, that the Company shall
not be required to preserve any right or franchise if the Board of Directors shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and that the loss thereof is not disadvantageous in any
material respect to the Holders. 
 SECTION 9.05. Payment of Taxes and Other Claims. The Company shall pay or discharge, or
cause to be paid or discharged, before the same shall become delinquent, (1) all taxes, assessments and governmental charges levied or imposed upon it or any Subsidiary or upon the income, profits or property of the Company or any Subsidiary,
and (2) all lawful claims for labor, materials and supplies which, if unpaid, might by law become a lien upon the property of the Company or any Subsidiary and have a Material Adverse Effect; provided, however, that the Company shall not be
required to pay or discharge or cause to be paid or discharged any such tax, assessment, charge or claim, the amount, applicability or validity of which is being contested in good faith by appropriate proceedings. 
 SECTION 9.06. No Senior Debt. The Company shall not, and shall not permit any of its Subsidiaries to incur, any indebtedness for money
borrowed that will be senior or pari passu to the Securities; provided, however, that the Company may obtain a line of credit from a financial institution having assets of not less than $200,000,000 in an amount up to $5,000,000, to use for working
capital. 
 SECTION 9.07. Statement as to Compliance; Notice of Default. The Company shall deliver to the Trustee, within
120 days after the end of each fiscal year of the Company, a certificate from the Company’s Chief Executive Officer, Chief Financial Officer or principal accounting officer as to his or her knowledge of the Company’s compliance with all
terms, conditions and provisions under this Indenture and, in the event of any noncompliance, specifying such noncompliance and the nature and status thereof. As of the date hereof, the Company’s fiscal year ends on December 31. For
purposes of this Section 9.06, such compliance shall be determined without regard to any period of grace or requirement of notice under this Indenture. The Company, within five Business Days of becoming aware of the occurrence of any Default or
Event of Default, shall deliver written notice to the Trustee of the occurrence thereof. 
 SECTION 9.08. Waiver of Certain
Covenants. The Company may omit in any particular instance to comply with any term, provision or condition set forth in Section 9.04 or 9.05 if, before the time for such compliance, the Holders of at least a majority in principal
amount of the Outstanding Securities, by Act of such Holders, either waive such compliance in such instance or generally waive compliance with such covenant or condition, but no such waiver shall extend to or affect such covenant or condition except
to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect. 
 SECTION 9.09. Rule 144A Information Requirement. Within the period prior to the expiration of the holding period applicable to sales
thereof under Rule 144(k) under the Securities Act (or any successor provision), the Company covenants and agrees that it shall, during any period in which it is not subject to Section 13 or 15(d) under the Exchange Act, make available to any
Holder or beneficial owner of Securities that continue to be Restricted Securities, in connection with any sale thereof, and to any prospective purchaser of Securities from such holder or beneficial owner, the information required pursuant to Rule
144A(d)(4) under the Securities Act upon the request of any such holder or beneficial owner of the Securities, and the Company shall take such further action as any holder or beneficial owner of such Securities may reasonably request, all to the
extent required from time to time to enable such holder or beneficial owner to sell its Securities without registration under the Securities Act within the limitation of the exemption provided by Rule 144A, as such rule may be amended from time to
time.

 ARTICLE 10 
 REDEMPTION OF SECURITIES 
 SECTION 10.01.
Optional Redemption by the Company. 
 (a) [Reserved]. 
 (b) The Securities may be redeemed at the election of the Company, as a whole or from time to time in part, at any time after July 6,
2009, and prior to maturity (an “Optional Redemption”), upon notice as set forth in Section 10.04, at a redemption price of 100% of the principal amount so redeemed, together with accrued and unpaid interest (including
Liquidated Damages, if any), if any, up to but not including the date fixed for redemption (the “Redemption Price”); provided, however, that the Securities will not be redeemable during such period unless the Closing Price
per share of Common Stock exceeds 150% of the Conversion Price for at least 20 Trading Days within a period of 30 consecutive Trading Days ending within five Trading Days immediately preceding the aforesaid notice to Holders. 
 SECTION 10.02. Election to Redeem; Notice to Trustee. The election of the Company to redeem any Securities shall be evidenced by a Board
Resolution. In case of any redemption at the election of the Company of all or any part of the Securities pursuant to Section 10.01 (Optional Redemption), the Company shall, at least 15 days prior to the giving of the notice of redemption in
Section 10.04 to the Holders (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee of the Redemption Date and of the principal amount of Securities to be redeemed. In the case of any redemption of Securities prior
to the expiration of any restriction on such redemption provided in the terms of such Securities or elsewhere in this Indenture, the Company shall furnish the Trustee with an Officers’ Certificate evidencing compliance with all such
restrictions. 
 SECTION 10.03. Selection by Trustee of Securities to Be Redeemed. If less than all the Securities are to be
redeemed, the particular Securities to be redeemed shall be selected not more than 60 days and not less than 30 days prior to the Redemption Date by the Trustee, from the Outstanding Securities not previously called for redemption, by lot, pro rata
or any other method that complies with the requirements of any exchange on which the Securities are listed or quoted and that the Trustee shall deem fair and appropriate. 
 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, solely for purposes of determining the aggregate principal amount of the Securities to be redeemed, to be the portion selected for redemption (provided, however, that the Holder of such Security so converted and deemed redeemed shall
not be entitled to any interest payment as a result of such deemed redemption except for such interest payment as such Holder would have otherwise been entitled to receive upon conversion of such Security). Securities that have been converted during
a selection of Securities to be redeemed may be treated by the Trustee as Outstanding for the purpose of such selection. 
 Securities in
denominations of $1,000 may only be redeemed in whole. The Trustee may select for redemption portions (equal to $1,000 or any integral multiple thereof) of the principal of Securities that have denominations larger than $1,000. 
 The Trustee shall promptly notify the Company and the Security Registrar (if other than itself) in writing of the Securities selected for redemption and,
in the case of any Securities selected for partial redemption, the principal amount thereof to be redeemed. 
 For all purposes of this
Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities shall relate, in the case of any Security redeemed or to be redeemed only in part, to the portion of the principal amount of such Security
which has been or is to be redeemed. 
 SECTION 10.04. Notice of Redemption. Notice of redemption shall be given in the
manner provided in Section 1.07, at least 30 days, but not more than 60 days, prior to the Redemption Date; provided, that failure to 

  

 36 








 
give such notice in the manner herein provided to the Holder of any Security designated for redemption as a whole or in part, or any defect in the notice to
any such Holder, shall not affect the validity of the proceedings for the redemption of any other such Security or portion thereof. 
 All
notices of redemption shall state: 
 (a) the Redemption Date; 
 (b) the Redemption Price; 
 (c) [Reserved]; 
 (d) if less than all Outstanding Securities are to be redeemed, the
identification (and, in the case of partial redemption, the principal amount) of the particular Securities to be redeemed; 
 (e) if any Security is to be redeemed in part only, the portion of the principal amount of such Security to be redeemed, and the notice that relates to such Security shall state that on and after the Redemption Date, upon surrender of such
Security, the holder shall receive, without a charge, a new Security or Securities of authorized denominations for the principal amount thereof remaining unredeemed; 
 (f) [Reserved]; 
 (g) that on the Redemption Date, the Redemption Price shall become due and payable upon each such Security, or the portion thereof, to be redeemed and, if applicable, that interest thereon shall cease to accrue on and after said date;

 (h) the Place or Places of Payment where such Securities are to be surrendered for payment of the Redemption Price;

 (i) that Securities called for redemption must be presented and surrendered to the Paying Agent to collect the redemption
price; 
 (j) the then current Conversion Price; 
 (k) that the Securities called for redemption may be converted at any time before the close of business on the last Business Day prior to
the Redemption Date; 
 (l) the CUSIP number of such Security, if any; and 
 (m) that a Holder of Securities who desires to convert Securities must satisfy the requirements for conversion contained in such
Securities. 
 Notice of redemption of Securities to be redeemed shall be given by the Company or, at the Company’s request, by the
Trustee in the name and at the expense of the Company. 
 SECTION 10.05. Deposit of Redemption Price. Not later than 11:00
a.m. New York City time on the Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 9.03) an amount of money
sufficient to pay, on the Redemption Date, the Redemption Price of all the Securities or portions thereof that are to be redeemed on that date, other than Securities or portions thereof called for redemption on that date that have been delivered by
the Company to the Trustee for cancellation or have been converted. Upon written request, the Trustee or the Paying Agent, as the case may be, shall return to the Company no later than 5 Business Days after such request any money not required to pay
such Redemption Price. 
 SECTION 10.06. Securities Payable on Redemption Date. Notice of redemption having been given as
aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified, and from and after such date (unless the Company shall default in the payment of the Redemption Price) such
Securities shall cease to bear interest. Upon surrender of any such 

  

 37 








 
Security for redemption in accordance with said notice, such Security shall be paid by the Company at the Redemption Price. 
 If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the Redemption Price, shall, until paid, bear interest
from the Redemption Date at the rate borne by the Security and such Security shall remain convertible into Common Stock until the Redemption Price, and any such accrued interest, shall have been paid or duly provided for. 
 SECTION 10.07. Securities Redeemed in Part. Any Security that is to be redeemed only in part (pursuant to the provisions of this
Article) shall be surrendered at a Place of Payment therefor (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder
thereof or his 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 unredeemed portion of the principal of the Security so surrendered. 
 ARTICLE 11 
 REPURCHASE AT OPTION OF
HOLDERS UPON CHANGE IN CONTROL 
 SECTION 11.01. Right
to Require Repurchase. In the event that a Change in Control shall occur, each Holder shall have the right, at the Holder’s option, to require the Company to repurchase all of such Holder’s Securities, or any portion of the
principal amount thereof that is an integral multiple of $1,000 (provided that no single Security may be repurchased in part unless the portion of the principal amount of such Security to be outstanding after such repurchase is equal to $1,000 or an
integral multiple of $1,000), on the date (the “Repurchase Date”) that is 45 Business Days after the date of the occurrence of a Change in Control at a purchase price equal to 100% of the principal amount plus interest (including
Liquidated Damages, if any) accrued and unpaid to the Repurchase Date (the “Repurchase Price”). The Repurchase Price shall be paid in cash. 
 SECTION 11.02. Notices; Method of Exercising Repurchase Right, Etc. (a) Unless the Company shall have theretofore called for redemption all of the Outstanding Securities, on or before the date that is 30
Business Days after the occurrence of a Change in Control, the Company shall give notice to all Holders of Outstanding Securities and to the Trustee (the “Company Notice”) of the occurrence of the Change in Control and of the
repurchase right set forth herein arising as a result thereof. 
 Each Company Notice shall state: 
 (i) the date of such Change in Control and, briefly, the events causing such Change in Control; 
 (ii) the date by which the Change in Control Purchase Notice (as defined below) must be delivered; 
 (iii) the Repurchase Date; 
 (iv) the Repurchase Price; 
 (v) a description of the procedure that a Holder must follow to
exercise a repurchase right;

(viii) briefly, the conversion rights of Holders of Securities;

 38 








 Promptly after giving the Company Notice to the Holders of Outstanding Securities and to the Trustee, the
Company shall cause a copy of the Company Notice to be published in The Wall Street Journal or another daily newspaper of national circulation and will also post such notice on the Company’s website. 
 (b) [Intentionally Omitted] 
 (c) To exercise a repurchase right, a Holder must deliver to the Trustee or at the office or agency maintained by the Company for such purpose in the Borough of Manhattan, The City of New York pursuant to
Section 9.02, prior to the close of business on or before the Repurchase Date, (i) written notice of the Holder’s exercise of such right (the “Change in Control Purchase Notice”), which notice shall set forth
(A) the name of the Holder, (B) the certificate numbers of the Securities with respect to which the repurchase right is being exercised, (C) the principal amount of the Securities to be repurchased (and, if any Security is to be
repurchased in part, the portion of the principal amount thereof to be repurchased, which shall be in integral multiples of $1,000) and (D) a statement that an election to exercise the repurchase right is being made thereby pursuant to the
applicable provisions of the Securities and (ii) surrender the Securities subject to the Change in Control Purchase Notice. 
 (d) On or prior to the Repurchase Date the Company shall deposit with the Trustee or with the Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 9.03) an amount of
money sufficient to pay the Repurchase Price of the Securities that are to be repaid on the Repurchase Date. On the Repurchase Date, the Trustee, a Paying Agent (or, if the Company is acting as its own Paying Agent, the Company) shall repurchase all
such Securities validly tendered prior to such date. 
 In the event that a Holder has previously delivered a Change in Control Purchase
Notice, but failed to surrender the Security with respect to which such Change in Control Purchase Notice relates, then so long as the Trustee or the Paying Agent holds (or, if the Company is acting as its own Paying Agent, the Company segregates
and holds in trust as provided in Section 9.03) money sufficient to pay the Repurchase Price in respect of such Security, then such Security shall cease to be Outstanding for the purposes of this Indenture on the Repurchase Date and all rights
of the Holder thereof other than the right to receive the Repurchase Price shall terminate. 
 (e) All Securities delivered
for repurchase shall be delivered to the Trustee to be canceled in accordance with the provisions of Section 3.08. 
 (f)
If any Security (or portion thereof) surrendered for repurchase shall not have been repurchased on the Business Day following the Repurchase Date, the Repurchase Price in respect of such Security shall, until paid, bear interest from the Business
Day following the Repurchase Date at the rate borne by the Security and such Security shall remain convertible into Common Stock until the Repurchase Price and any such accrued interest shall have been paid or duly provided for. 
 (g) Any Security that is to be repurchased only in part shall be surrendered to the Trustee or any such Paying Agent (or if the Company is
acting as its own Paying Agent, the Company) 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, containing identical terms and
conditions, each in an authorized denomination in aggregate principal amount equal to and in exchange for the portion of the principal of the Security so surrendered that was not repurchased. 
 (h) Any Holder that has delivered a Change in Control Purchase Notice shall have the right to withdraw such notice by delivery of a
written notice of withdrawal to the Trustee or any such Paying Agent prior to the close of business on the Repurchase Date. The notice of withdrawal shall state the principal amount and the certificate numbers of the Securities as to which the
withdrawal notice relates and the principal amount, if any, that remains subject to the Change in Control Purchase Notice. A Security in respect of which a Holder has exercised its right to require repurchase upon a Change in Control may thereafter
be converted 

  

 39 








 
into Common Stock only if, and at such time as, such Holder withdraws its Change in Control Purchase Notice in accordance with the preceding sentence.

 (i) [Intentionally Omitted] 
 (j) [Intentionally Omitted] 
 (k) [Intentionally Omitted] 
 (l) Notwithstanding anything to the contrary in this Section 11.02, the Company shall not be required to give the Company Notice

Holders of all Outstanding Securities and to the Trustee, (B) such Person repurchases all Outstanding Securities validly tendered and not withdrawn, and (C) such Person makes all payments with respect thereto. This Section 11.02(l)
shall not relieve the Company of any of its obligations under this Indenture or any Security; provided, however, that if another Person makes the offer to repurchase Outstanding Securities as set forth in this Section, the Company shall not
be obligated to give the Company Notice. 
 (m) Absent, and except to the extent of, the Trustee’s receipt of a Company
Notice of a Change in Control, the Trustee shall not be under any duty to determine or monitor whether a Change in Control has occurred, from time to time. 
 SECTION 11.03. Certain Definitions. For purposes of this Article 11:

CONVERSION 
 SECTION 12.01. Conversion Privilege, Conversion Rate and Conversion Price. Subject to and upon compliance with the provisions of this Article 12, at the option of the Holder thereof, any Security or any portion of the
principal amount thereof that is $1,000 or an integral multiple of $1,000 may be converted at any time after original issuance thereof through the close of business on September 30, 2010 into that number of fully paid and non-assessable shares
of Common Stock obtained by multiplying the Conversion Rate then in effect by each $1,000 principal amount of Securities surrendered for conversion. In case a Security or portion thereof has previously been called for redemption at the election of
the Company, such conversion right in respect of the Security or portion so called shall expire at the close of business, New York City time, on the last Business Day prior to the Redemption Date, unless the Company defaults in making the payment
due upon redemption. A Security in respect of which a Holder has delivered a Change in Control Purchase Notice (as defined in Article 11 hereof) exercising the option of such Holder to require the Company to purchase such Security may be
converted only if such notice and the Security is withdrawn by a written notice of withdrawal delivered by the Holder to the Trustee or any Paying Agent prior to the close of business on the Repurchase Date, in accordance with the terms of this
Indenture. 
 The price at which shares of Common Stock shall be delivered upon conversion (herein called the “Conversion
Price”) shall be initially approximately $2.118 per share of Common Stock, which is equal to a conversion rate of 472.1435 shares per $1,000 principal amount of the Securities (the “Conversion Rate”). The Conversion Rate
shall be adjusted in certain instances as provided in Section 12.04 and, in every instance in which an adjustment is made to the Conversion Rate, a corresponding adjustment shall be made to the Conversion Price. The adjusted Conversion Price
shall equal at any time 1,000 divided by the then adjusted Conversion Rate. 
 In the case of a Change in Control that the Company knows or
reasonably should know will occur, the Company will notify the Holders and Trustee in writing at least 15 Trading Days prior to the date on which such 

  

 41 








 
Change in Control becomes effective (provided that the Company shall make public disclosure thereof prior to or contemporaneously with such notification to
the Holders). If the Company does not know, and should not reasonably know, that a Change in Control will occur until a date that is within 15 Trading Days before the anticipated Effective Date (as defined below) or other applicable event, the
Company will notify the Holders and the Trustee in writing as promptly as practicable after the Company has knowledge of such Change in Control or such other event (provided that the Company shall make public disclosure thereof prior to or
contemporaneously with such notification to the Holders). 
 If a Holder elects to convert its Securities in connection with a corporate
transaction that constitutes a Change in Control at any time on or prior to July 6, 2010, pursuant to which 10% or more of the consideration for the Common Stock (other than cash payments for fractional shares and cash payments made in respect
of dissenters’ appraisal rights) in such transaction consists of cash or securities (or other property) that are not traded or scheduled to be traded immediately following such transaction on a U.S. national securities exchange or any United
States system of automated dissemination of quotations of securities prices or an established over-the-counter trading market in the United States (a “Non-Stock Change in Control”), then, in addition to the Common Stock such Holder
is entitled to receive upon such conversion, the Company will pay a make-whole premium (the “Make-Whole Premium”) in cash to such Holders, which Make-Whole Premium shall be due and payable in accordance with Section 12.02 of
this Indenture; provided that if the Share Price in such transaction is less than U.S.$1.83 (subject to adjustment as described below), no Make-Whole Premium shall be paid by the Company. For the avoidance of doubt, the Make-Whole Premium provided
for in this Section 12.01 shall only be paid with respect to the Securities being converted in connection with such Non-Stock Change in Control and shall not be effective as to any Securities not so converted. 
 The Make-Whole Premium will be expressed as a percentage of the principal amount of the Securities and will be determined by the Company by reference to
the table below, based on the date the Non-Stock Change in Control becomes effective (the “Effective Date”) and the share price paid per share of Common Stock in the corporate transaction (the “Share Price”);
provided that if holders of the Common Stock receive only cash in such corporate transaction, the Share Price shall be the cash amount paid per share. Otherwise, the Share Price will be the average of the Closing Price on the five Trading
Days prior to but not including the Effective Date; provided further that if the Effective Date is between two Effective Dates in the table, the Company shall determine the Make-Whole Premium by a straight-line interpolation between the
percentage set forth for the two dates, as applicable, based on a 365-day year.

 The Share Prices set forth in the first row of the table (i.e., column headers) above will be
adjusted as of any date on which the Conversion Rate of the Securities is adjusted pursuant to this Indenture. The adjusted Share Prices will equal the Share Prices applicable immediately prior to such adjustment, multiplied by a fraction, the
numerator of which is the Conversion Rate as so adjusted giving rise to the Closing Rate adjustment and the denominator of which is the Conversion Rate immediately prior to the adjustment. 
 SECTION 12.02. Exercise of Conversion Privilege. In order to exercise the conversion privilege with respect to any Security in
definitive form, the Holder of any Security to be converted shall surrender such Security, duly endorsed or assigned to the Company or in blank, at any office or agency maintained by the 

  

 42 








 
Company pursuant to Section 9.02, accompanied by (a) written notice to the Company in substantially the form of conversion notice attached to the
form of Security attached as Exhibit A hereto at such office or agency that the Holder elects to convert such Security or, if less than the entire principal amount thereof is to be converted, the portion thereof to be converted, (b) the
funds, if any, required by this Section 12.02, and (c) if shares or any portion of such Security not to be converted are to be issued in the name of a Person other than the Holder thereof, the name of the Person in which to issue such
shares and the transfer taxes, if any, required to be paid by the Holder pursuant to Section 12.08. 
 In order to exercise the
conversion privilege with respect to any interest in a global Security, the beneficial owner must complete, or cause to be completed, the appropriate instruction form for conversion pursuant to the depositary’s book-entry conversion program,
deliver, or cause to be delivered, by book-entry delivery, an interest in such global Security, furnish appropriate endorsements and transfer documents if required by the Company or the Trustee or other agent, and pay the funds, if any, required by
this Section 12.02 and any transfer taxes if required pursuant to Section 12.08. 
 As promptly as practicable after satisfaction
of the requirements for conversion set forth above, the Company shall issue and shall deliver to such Holder a certificate or certificates for the number of full shares of Common Stock issuable upon the conversion of such Security or portion thereof
in accordance with the provisions of this Article and a check or cash in respect of any fractional interest in respect of a share of Common Stock arising upon such conversion, as provided in Section 12.03, and in respect of any Make-Whole
Premium. In case any Security of a denomination greater than $1,000 shall be surrendered for partial conversion, and subject to Article 2, the Company shall execute, and the Trustee shall authenticate and deliver to the holder of the Security
so surrendered, without charge, a new Security or Securities in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Security. 
 Each conversion shall be deemed to have been effected as to any such Security (or portion thereof) on the date on which the requirements set forth above
in this Section 12.02 have been satisfied as to such Security (or portion thereof), and the Person in whose name any certificate or certificates for shares of Common Stock shall be issuable upon such conversion shall be deemed to have become on
said date the holder of record of the shares represented thereby; provided however that any such surrender on any date when the stock transfer books of the Company shall be closed shall constitute the Person in whose name the certificates are
to be issued as the record holder thereof for all purposes on the next succeeding day on which such stock transfer books are open, but such conversion shall be at the Conversion Rate in effect on the date upon which such Security shall be
surrendered. 
 Any Security or portion thereof surrendered for conversion during the period from the close of business on the record date
for any interest payment date to the close of business on the Business Day next preceding the following interest payment date that has not been called for redemption during such period, shall be accompanied by payment, in immediately available funds
or other funds acceptable to the Company, of an amount equal to the interest otherwise payable on such interest payment date on the principal amount being converted; provided however that no such payment need be made to the extent any overdue
interest shall exist at the time of conversion with respect to any such Security or portion thereof. On conversion of a Security, that portion of accrued and unpaid interest, if any, remaining unpaid on such conversion shall not be cancelled,
extinguished or forfeited, but rather shall be deemed to be paid in full to the Holder thereof through delivery of the Common Stock (together with the cash payment, if any, in lieu of fractional shares) in exchange for the Security being converted
pursuant to the provisions hereof. Except as provided above in this Section 12.02, no payment or other adjustment shall be made for interest accrued on any Security converted or for dividends on any shares issued upon the conversion of such
Security as provided in this Article. 
 Upon the conversion of an interest in a global Security, the Trustee (or other conversion agent
appointed by the Company), shall make a notation on such global Security as to the reduction in the principal amount represented thereby. The Company shall notify the Trustee in writing of any conversions of Securities effected through any
Conversion Agent other than the Trustee. 
  

 43 








 SECTION 12.03. Fractions of Shares. No fractional shares of Common Stock shall be issued
upon conversion of Securities. If more than one Security shall be surrendered for conversion at one time by the same Holder, the number of full shares that shall be issuable upon conversion thereof shall be computed on the basis of the aggregate
principal amount of the Securities (or specified portions thereof) so surrendered. Instead of any fractional share of Common Stock that would otherwise be issuable upon conversion of any Security (or specified portions thereof), the Company shall
pay a cash adjustment in respect of such fraction in an amount equal to the same fraction of the Closing Price per share of the Common Stock at the close of business on the Trading Day immediately preceding such day. 
 “Trading Day” shall mean each day on which the primary securities exchange or quotation system that is used to determine the Closing
Price is open for trading or quotation. 
 “Closing Price” of a single share of Common Stock on any Trading Day shall mean
the closing sale price per share for the Common Stock (or if no closing sale price is reported, the average of the bid and ask prices) on such Trading Day on the principal United States national securities exchange on which the Common Stock is
traded or, if the Common Stock is not listed on a United States national stock exchange, any United States system of automated dissemination of quotations of securities prices or an established over-the-counter trading market in the United States.
In the absence of the foregoing, the Company’s Board of Directors will determine the Closing Price on such reasonable basis as it considers appropriate based on its reasonable good faith judgment. 
 SECTION 12.04. Adjustment of Conversion Rate.
 (a) In case the Company shall pay or make a dividend or other distribution on its Common Stock exclusively in Common Stock, the Conversion Rate in effect at the opening of business on the earlier of the day next
following such dividend or other distribution or the date fixed for the determination of stockholders entitled to receive such dividend or other distribution shall be adjusted so that a Holder upon conversion shall be entitled to receive that number
of shares of Common Stock it would have been entitled to after such dividend or other distribution if it had converted its Security immediately prior to such dividend or other distribution. 
 (b) In case the Company shall pay or make a dividend or other distribution on its Common Stock consisting exclusively of, or shall
otherwise issue to all holders of its Common Stock, rights, warrants or options entitling the holders thereof, for a period not exceeding 45 days, to subscribe for or purchase shares of Common Stock at a price per share less than the current market
price per share (determined as provided in Section 12.04(h)) of the Common Stock on the date fixed for the determination of stockholders entitled to receive such rights, warrants or options, the Conversion Rate in effect at the opening of
business on the day following the date fixed for such determination shall be increased by multiplying such Conversion Rate by a fraction of which the numerator shall be the number of shares of Common Stock outstanding at the close of business on the
date fixed for such determination plus the number of shares of Common Stock so offered for subscription or purchase and the denominator shall be the number of shares of Common Stock outstanding at the close of business on the date fixed for such
determination plus the number of shares of Common Stock which the aggregate price of the total number of shares so offered would purchase at the current market price per share (determined as provided in Section 12.04(h)), such increase to
become effective immediately after the opening of business on the day following the date fixed for such determination. 
 (c)
In case outstanding shares of Common Stock shall be subdivided into a greater number of shares of Common Stock, the Conversion Rate in effect at the opening of business on the day following the day upon which such subdivision becomes effective shall
be proportionately increased, and, conversely, in case outstanding shares of Common Stock shall each be combined into a smaller number of shares of Common Stock, the Conversion Rate in effect at the opening of business on the day following the day
upon which such combination becomes effective shall be proportionately reduced, such increase or reduction, as the case may be, to become effective immediately after the opening of business on the day following the day upon which such subdivision or
combination becomes effective. 
  

 44 








 (d) In case the Company shall, by dividend or otherwise, distribute to all holders of its
Common Stock evidences of its indebtedness, shares of any class of capital stock, securities, cash or assets (excluding any rights, warrants or options referred to in Section 12.04(b), any dividend or distribution paid exclusively in cash and
any dividend or distribution referred to in Section 12.04(a)), the Conversion Rate shall be adjusted by multiplying the Conversion Rate in effect immediately prior to the earlier of such distribution or the determination of stockholders
entitled to receive such distribution by a fraction of which the numerator shall be the current market price per share (determined as provided in Section 12.04(h)) and the denominator shall be such current market price less the fair market
value (as determined in good faith by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution), on the date of such effectiveness, of the portion of the evidences of indebtedness, shares of capital stock,
securities, cash and assets so distributed applicable to one share of Common Stock, such adjustment to become effective immediately prior to the opening of business on the day next following the later of (i) the date fixed for the payment of
such distribution and (ii) the date 20 days after the notice relating to such distribution is given pursuant to Section 12.06 (such later date of (i) and (ii) being referred to as the “Reference Date”). The
provisions of this Section 12.04(d) shall not be applicable to an event covered by Section 12.04(k). For purposes of this Section 12.04(d) and Sections 12.04(a) and 12.04(b), any dividend or distribution for which an adjustment is
being made pursuant to this Section 12.04(d) that also includes shares of Common Stock or rights, warrants or options to subscribe for or purchase shares of Common Stock shall be deemed instead to be (A) a dividend or distribution of the
evidences of indebtedness, cash, property, shares of capital stock or securities other than such shares of Common Stock or such rights, warrants or options (making any Conversion Rate adjustment required by this Section 12.04(d)) immediately
followed by (B) a dividend or distribution of such shares of Common Stock or such rights (making any further Conversion Rate adjustment required by Sections 12.04(a) or 12.04(b)), except (1) the record date of such dividend or distribution
as defined in this Section 12.04(d) shall be substituted as “the date fixed for the determination of stockholders entitled to receive such dividend or other distributions”, “the date fixed for the determination of stockholders
entitled to receive such rights, warrants or options” and “the date fixed for such determination” within the meaning of Sections 12.04(a) and 12.04(b) and (2) 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 this 12.04(d). 
 (e) In case the Company shall, by dividend or otherwise, make a distribution to all holders of its Common Stock exclusively in cash, the Company shall, in all cases, at the time of such distribution, make a cash
payment to the Holders of all outstanding Securities equal to the amount of cash such Holder would have received with respect to such distribution for all of its Securities had such Holder converted its Securities into Common Stock immediately prior
to the close of business on the date fixed for the determination of the stockholders of record entitled to such distribution. 
 (f) In case a successful tender or exchange offer, other than an odd lot offer, made by the Company or any Subsidiary for all or any portion of the Common Stock shall involve an aggregate consideration having a fair market value (as
determined in good faith by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution) at the last time (the “Expiration Time”) tenders or exchanges may be made pursuant to such tender or
exchange offer (as it may be amended) that exceeds the current market price per share (determined as provided in Section 12.04(h)) of the Common Stock outstanding (including any tendered shares) on the Expiration Time times the number of shares
of Common Stock outstanding (including any tendered shares) as of the Expiration Time, then, in each case, the Conversion Rate shall be adjusted by multiplying the Conversion Rate in effect immediately prior to the Expiration Time by a fraction of
which (i) the denominator shall be (x) the product of the current market price per share (determined as provided in Section 12.04(h)) of the Common Stock on the Trading Day next succeeding the Expiration Time times the number of
shares of Common Stock outstanding (including any tendered or exchanged shares) at the Expiration Time minus (y) 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, 

  

 45 








 
being referred to as the “Purchased Shares”) and (ii) the numerator shall be the product of (x) such current market price per
share (determined in accordance with Section 12.04(h)) on the Trading Day next succeeding the Expiration Time times (y) such number of outstanding shares at the Expiration Time less the number of Purchased Shares, such increase to become
effective immediately prior to the opening of business on the day following the Expiration Time. 
 (g) In case the
September 30, 2008 Trailing Twelve Month Net Income shall be less than $0.00, the Conversion Rate shall be increased to 546.4481, which number shall be subject to adjustment from the date hereof as set forth in clauses (a) through
(f) of this Section 12.04 (the “Operating Adjustment”); provided, however, that no Operating Adjustment shall occur in the event that the simple average of the daily Volume-Weighted Average Price for the five
Business Days immediately preceding the Operating Adjustment Determination Date and the five succeeding Business Days commencing on the Operating Adjustment Determination Date shall exceed one hundred twenty-five percent (125%) of the
Conversion Price. The Operating Adjustment shall be effective, if at all, on the tenth business day following the Operating Adjustment Determination Date. 
 The “Operating Adjustment Determination Date” shall be the earlier of the date on which the Company files its quarterly report on Form 10-Q under the Exchange Act for the three and nine months ended
September 30, 2008 or November 17, 2008. 
 The “September 30, 2008 Trailing Twelve Month Net Income” of the
Company shall equal the aggregate net income (or loss) plus costs or expenses attributable to stock based compensation and any intangible asset impairments, including but not limited to, investments and goodwill, of the Company for the four
consecutive fiscal quarters ending immediately prior to October 1, 2008, which shall be calculated by the Company by deriving such amounts from the Company’s quarterly report on form 10-Q for the period ending September 30, 2008 and
from the Company’s annual report on Form 10-K for the year ended December 31, 2007, consistent with the amounts reported in such filings. In the event that the Company shall have changed its fiscal year-end period, the September 30,
2008 Trailing Twelve Month Net Income shall be based on such relevant periodic reports that the Company shall have filed, and the Company shall make such notification of adjustment as may be required under this Section 12.04(g). 
 The “Volume-Weighted Average Price” per share of the of the Common Stock on a Trading Day is the volume-weighted average price per share
of the Common Stock on the Nasdaq Global Market or, if the Common Stock is not then listed on the Nasdaq Global market, on the principal exchange or over-the-counter market on which the Common Stock is then listed or traded, from 9:30 a.m. to 4:00
p.m., New York City time, on that Trading Day, as displayed by Bloomberg. If such price is not available, the Volume-Weighted Average Price means the market value per share of the Common Stock on such day as determined by a nationally recognized
investment banking firm retained for this purpose by the Company. 
 The Company shall notify the Holders and the Trustee in the manner
provided in Section 12.05 of any adjustment in the Conversion Rate under this Section 12.04(g), setting forth the date on which such adjustment is effective as provided herein. 
 (h) For the purpose of any computation under Sections 12.04(b), (d) and (e), the current market price per share of Common Stock on
any date in question shall be deemed to be the average of the daily Closing Prices per share of Common Stock for the ten consecutive Trading Days immediately prior to the date in question; provided, however, that (i) if the
“ex” date (as hereinafter defined) for any event (other than the issuance or distribution requiring such computation) that requires an adjustment to the Conversion Rate pursuant to Section 12.04(a), (b), (c), (d), (e), (f) or
(g) (“Other Event”) occurs on or after the 20th Trading Day prior to the date in question and prior to the “ex” date for the issuance or distribution requiring such computation (the “Current Event”),
the Closing Price for each Trading Day prior to the “ex” date for such Other Event shall be adjusted by multiplying such Closing Price by the reciprocal of the fraction by which the Conversion Rate is so required to be adjusted as a result
of such Other Event, (ii) if the “ex” date for any 

  

 46 








 
Other Event occurs after the “ex” date for the Current Event and on or prior to the date in question, the Closing Price for each Trading Day on and
after the “ex” date for such Other Event shall be adjusted by multiplying such Closing Price by the fraction by which the Conversion Rate is so required to be adjusted as a result of such Other Event, (iii) if the “ex” date
for any Other Event occurs on the “ex” date for the Current Event, one of those events shall be deemed for purposes of clauses (i) and (ii) of this proviso to have an “ex” date occurring prior to the “ex” date
for the Other Event, and (iv) if the “ex” date for the Current Event is on or prior to the date in question, after taking into account any adjustment required pursuant to clause (ii) of this proviso, the Closing Price for each
Trading Day on or after such “ex” date shall be adjusted by adding thereto the amount of any cash and the fair market value on the date in question (as determined in good faith by the Board of Directors in a manner consistent with any
determination of such value for purposes of Section 12.04(d) or (e), whose determination shall be conclusive and described in a Board Resolution) of the portion of the rights, warrants, options, evidences of indebtedness, shares of capital
stock, securities, cash or property being distributed applicable to one share of Common Stock. For the purpose of any computation under Section 12.04(f), the current market price per share of Common Stock on any date in question shall be deemed
to be the average of the daily Closing Prices for the five consecutive Trading Days selected by the Company commencing on or after the latest (the “Commencement Date”) of (i) the date 20 Trading Days before the date in
question, (ii) the date of commencement of the tender or exchange offer requiring such computation and (iii) the date of the last amendment, if any, of such tender or exchange offer involving a change in the maximum number of shares for
which tenders are sought or a change in the consideration offered, and ending not later than the Trading Day next succeeding the Expiration Time of such tender or exchange offer (or, if such Expiration Time occurs before the close of trading on a
Trading Day, not later than the Trading Day during which the Expiration Time occurs); provided, however, that if the “ex” date for any Other Event (other than the tender or exchange offer requiring such computation) occurs on or
after the Commencement Date and on or prior to the Trading Day next succeeding the Expiration Time for the tender or exchange offer requiring such computation, the Closing Price for each Trading Day prior to the “ex” date for such Other
Event shall be adjusted by multiplying such Closing Price by the reciprocal of the same fraction by which the Conversion Rate is so required to be adjusted as a result of such other event. For purposes of this paragraph, the term “ex”
date, (i) when used with respect to any issuance or distribution, means the first date on which the Common Stock trades regular way on the relevant exchange or in the relevant market from which the Closing Price was obtained without the right
to receive such issuance or distribution, (ii) when used with respect to any subdivision or combination of shares of Common Stock, means the first date on which the Common Stock trades regular way on such exchange or in such market after the
time at which such subdivision or combination becomes effective, and (iii) when used with respect to any tender or exchange offer means the first date on which the Common Stock trades regular way on such exchange or in such market after the
Expiration Time of such tender or exchange offer. 
 (i) In addition to those required by paragraphs (a), (b), (c), (d), (e),
(f) and (g) of this Section 12.04, to the extent permitted by applicable law, the Company from time to time may increase the Conversion Rate by any amount for any period of time if the period is at least twenty (20) days and the
Board of Directors shall have made a determination that such increase would be in the best interests of the Company, which determination shall be conclusive. Whenever the Conversion Rate is increased pursuant to the preceding sentence, the Company
shall give notice of the increase to the Holders of Securities in the manner provided in Section 1.06 at least fifteen (15) days prior to the date the increased Conversion Rate takes effect, and such notice shall state the increased
Conversion Rate and the period during which it will be in effect. 
 (j) No adjustment in the Conversion Rate shall be
required unless such adjustment would require an increase or decrease of at least 1% in the Conversion Rate; provided, however, that any adjustments, which by reason of this Section 12.04(j) are not required to be made, shall be carried
forward and taken into account in any subsequent adjustment. 
 (k) In the event that the Company distributes assets, debt
securities, rights, warrants or options (other than those referred to in Section 12.04(b)) pro rata to holders of Common Stock, and the fair market value of the portion of assets, debt securities, rights, warrants or options applicable to one
share of Common Stock 

  

 47 








 
distributed to holders of Common Stock exceeds the Average Sale Price (as defined below) per share of Common Stock, or such Average Sale Price exceeds such
fair market value by less than $1.00, then so long as any such assets, debt securities, rights, options or warrants have not expired or been redeemed by the Company, the Company shall make proper provision so that the Holder of any Security upon
conversion, rather than being entitled to an adjustment in the Conversion Rate, will be entitled to receive upon such conversion, in addition to the shares of Common Stock otherwise issuable upon conversion, the kind and amount of assets, debt
securities, rights, warrants and options such Holder would have received had such Holder converted its Security immediately prior to the date of determination of the holders entitled to such distribution. 
 “Average Sale Price” means the average of the Closing Prices of the Common Stock for the shorter of (i) 30 consecutive Trading Days
ending on the last full Trading Day prior to the Time of Determination (as defined below) with respect to the rights, options, warrants or distribution in respect of which the Average Sale Price is being calculated, or (ii) the period
(x) commencing on the date next succeeding the first public announcement of (a) the issuance of rights, options or warrants or (b) the distribution, in each case, in respect of which the Average Sale Price is being calculated and
(y) proceeding through the last full Trading Day prior to the Time of Determination with respect to the rights, options, warrants or distribution in respect of which the Average Sale Price is being calculated, or (iii) the period, if any,
(x) commencing on the date next succeeding the Ex-Dividend Time (as defined below) with respect to the next preceding (a) issuance of rights, warrants or options or (b) distribution, in each case, for which an adjustment is required
by the provisions of Section 12.04(b) or Section 12.04(k) and (y) proceeding through the last full Trading Day prior to the Time of Determination with respect to the rights, options, warrants, or distribution in respect of which the
Average Sale Price is being calculated. If the Ex-Dividend Time (or in the case of a subdivision, combination or reclassification, the effective date with respect thereto) with respect to a dividend, subdivision, combination or reclassification to
which Section 12.04(a), (b) or (c) applies occurs during the period applicable for calculating “Average Sale Price” pursuant to the definition in the preceding sentence, “Average Sale Price” shall be calculated for
such period in a manner determined in good faith by the Board of Directors to reflect the impact of such dividend, subdivision, combination or reclassification on the Closing Price of the Common Stock during such period. 
 “Time of Determination” means the time and date of the earlier of (i) the determination of stockholders entitled to receive rights,
warrants or options or a distribution, in each case, to which this Section 12.04 applies and (ii) the time (“Ex-Dividend Time”) immediately prior to the commencement of “ex-dividend” trading for such rights,
options, warrants or distribution on the New York Stock Exchange or such other national or regional exchange or market on which the shares of Common Stock are listed or quoted. 
 SECTION 12.05. Notice of Adjustments of Conversion Rate. Whenever the Conversion Rate and Conversion Price are adjusted as herein
provided, the Company shall compute the adjusted Conversion Rate and Conversion Price in accordance with Section 12.04 and shall prepare a certificate signed by the Chief Financial Officer of the Company setting forth the adjusted Conversion
Rate and Conversion Price and showing in reasonable detail the facts upon which such adjustment is based, and such certificate shall forthwith be filed (with a copy to the Trustee or the Conversion Agent) at each office or agency maintained for the
purpose of conversion of Securities pursuant to Section 9.02; and the Company shall forthwith cause a notice setting forth the adjusted Conversion Rate and Conversion Price to be mailed, first class postage prepaid, to each Holder of Securities
at its address appearing on the Security Register. Unless and until the Trustee (and the Conversion Agent, as the case may be) shall receive such notice, the Trustee (and the Conversion Agent, as the case may be) may assume without inquiry that the
Conversion Rate and Conversion Price have not been, and are not required to be, adjusted and that the last Conversion Rate and Conversion Price of which it has written notice remain in effect. 
 SECTION 12.06. Notice of Certain Corporate Action. In case: 
 (a) the Company shall declare a dividend (or any other distribution) on its Common Stock that would require a Conversion Rate adjustment
pursuant to Section 12.04(e); or 
  

 48 








 (b) the Company shall authorize the granting to all holders of its Common Stock of
rights, warrants or options to subscribe for or purchase any shares of capital stock of any class or of any other rights (excluding rights distributed pursuant to any stockholder rights plan); or 
 (c) of any reclassification of the Common Stock of the Company (other than a subdivision or combination of its outstanding shares of
Common Stock), or of any 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 transfer of all or substantially all of the assets of the Company; or

 (d) of the voluntary or involuntary dissolution, liquidation or winding up of the Company; or 
 (e) the Company or any Subsidiary of the Company shall commence a tender or exchange offer for all or a portion of the Company’s
outstanding shares of Common Stock (or shall amend any such tender or exchange offer); 
 then the Company shall cause to be filed at each
office or agency maintained for the purpose of conversion of Securities pursuant to Section 9.02, and shall cause to be mailed to all Holders at their last addresses as they shall appear in the Security Register, at least 20 days (or 10 days in
any case specified in clause 12.06(a) or 12.06(b) above) prior to the applicable record, effective or expiration date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend,
distribution or granting of rights, warrants or options, or, if a record is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such dividend, distribution, rights, warrants or options are to be determined,
or (y) the date on which such reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding up 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 shares of Common Stock for securities, cash or other property deliverable upon such reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding up, or (z) the date on which such
tender offer commenced, the date on which such tender offer is scheduled to expire unless extended, the consideration offered and the other material terms thereof (or the material terms of any amendment thereto). 
 SECTION 12.07. Company’s Obligation Regarding Common Stock. The Company shall at all times reserve and keep available, free from
preemptive rights, out of its authorized but unissued Common Stock, solely for the purpose of effecting the conversion of Securities, the whole number of shares of Common Stock then issuable upon the conversion in full of all Outstanding Securities.

 Before taking any action which would cause an adjustment reducing the Conversion Price below the then par value, if any, of the shares of
Common Stock issuable upon conversion of the Securities, the Company shall take all corporate action that may, in the opinion of its counsel, be necessary in order that the Company may validly and legally issue shares of such Common Stock at such
adjusted Conversion Price. 
 The Company covenants that if any shares of Common Stock to be provided for the purpose of conversion of
Securities hereunder require registration with or approval of any governmental authority under any federal or state law before such shares may be validly issued upon conversion, the Company shall in good faith and as expeditiously as practicable
endeavor to secure such registration or approval, as the case may be. 
 The Company further covenants that so long as the Common Stock shall
be listed on the New York Stock Exchange, The Nasdaq Stock Market, or any other national securities exchange the Company shall, if permitted by the rules of such exchange, list and keep listed so long as the Common Stock shall be so listed on such
market or exchange, all Common Stock issuable upon conversion of the Securities. 
 SECTION 12.08. Taxes on Conversions. The
Company shall pay any and all stamp, documentary or issuance taxes that may be payable in respect of the issue or delivery of shares of Common Stock on conversion of Securities pursuant hereto, but shall not pay any taxes measured by net income or
otherwise imposed on Holders in connection with a conversion. The Company shall not, however, be required to pay any tax that may 

  

 49 








 
be payable in respect of any transfer involved in the issue and delivery of shares of Common Stock in a name other than that of the Holder of the Security or
Securities to be converted, 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 any such tax, or has established to the satisfaction of the Company that such tax has
been paid. 
 SECTION 12.09. Covenant as to Common Stock. The Company covenants that all shares of Common Stock that may be
issued upon conversion of Securities shall upon issue be newly issued (and not treasury shares) and shall be duly authorized, validly issued, fully paid and nonassessable and, except as provided in Section 12.08, the Company shall pay all
taxes, liens and charges with respect to the issue thereof. 
 SECTION 12.10. Cancellation of Converted Securities. All
Securities delivered for conversion shall be delivered to the Trustee to be cancelled by or at the direction of the Trustee, which shall dispose of the same as provided in Section 3.08. 
 SECTION 12.11. Provisions in Case of Reclassification, Consolidation, Merger or Sale of Assets. In the event that the Company shall be a
party to any transaction (including any (i) recapitalization or reclassification of the 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 of the Common Stock), (ii) any consolidation of the Company with, or merger of the Company into, any other person, any merger of another person into the Company (other than a merger that does not result in a reclassification,
conversion, exchange or cancellation of outstanding shares of Common Stock of the Company), (iii) any sale, lease, transfer, conveyance or other disposition of all or substantially all of the assets of the Company or (iv) any compulsory
share exchange) pursuant to which the Common Stock is converted into the right to receive other securities, cash or other property, then lawful provision shall be made as part of the terms of such transaction whereby the Holder of each Security then
Outstanding shall have the right thereafter to convert such Security only into (subject to funds being legally available for such purpose under applicable law at the time of such conversion) the kind and amount of securities, cash and other property
receivable upon such transaction by a holder of the number of shares of Common Stock into which such Security might have been converted immediately prior to such transaction. The Company or the Person formed by such consolidation or resulting from
such merger or that acquired such assets or that acquired the Company’s shares of Common Stock, as the case may be, shall execute and deliver to the Trustee a supplemental indenture establishing such rights. Such supplemental indenture shall
provide for adjustments that, for events subsequent to the effective date of such supplemental indenture, shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article. In the event holders of Common Stock have
the opportunity to elect the form of consideration to be received in such reclassification, change, combination, consolidation, merger, sale or conveyance, the Company will make adequate provision whereby the Holders of the Securities shall have the
opportunity, on a timely basis, to determine the form of consideration into which all of the Securities, treated as a single class, shall be convertible. The form of consideration into which all of the Securities, treated as a single class, shall be
convertible, shall be determined by the Holders of a majority of the Securities (based on principal amount outstanding thereunder) who have made an election as to such form of consideration and shall be subject to any limitations to which all of the
holders of Common Stock are subject, such as pro rata reductions applicable to any portion of the consideration payable. In the event that the Holders do not make such election on or prior to the date 10 days after receipt of notice that such
election is required, then for the purposes of this Section 12.11 the kind and amount of securities, cash or other property receivable upon such reclassification, change, combination, consolidation, merger, sale or conveyance by each Holder
shall be deemed to be the kind and amount so receivable by holders of a plurality of the Common Stock. The above provisions of this Section 12.11 shall similarly apply to successive transactions of the foregoing type. 
 SECTION 12.12. Company’s Obligation. All calculations, adjustments, conversions and other determinations under this Article 12
shall be the sole responsibility and obligation of the Company. The Trustee (a) shall have no obligation to review, verify, challenge or contest any such calculation, adjustment, conversion or other determination and (b) shall not be
liable for any default or error by the Company under this Article 12.

commencing September 30, 2007 (each an “Interest Payment Date”) and beginning to accrue as of July 6, 2007, at said office or agency, in like coin or currency, at the rate of 5.45% per annum, until the principal

 FORM OF REVERSE OF SECURITY 
 TranSwitch Corporation 
 5.45% CONVERTIBLE NOTE DUE 2010 
 This Security is one of a duly authorized issue of securities of the Company designated as its 5.45% Convertible Notes due 2010 (herein called the
“Securities”). The Securities are limited in aggregate principal amount to $25,013,000 as adjusted from time to time on the books and records of the Trustee, which may be issued under an Indenture, dated as of July 6, 2007 (the
“Indenture”), between the Company and U.S. BANK NATIONAL ASSOCIATION, as Trustee for the Holders of Securities issued under said Indenture (herein called the “Trustee,” which term includes any successor trustee
under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee, and the Holders
of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. 
 The Holder of this Security
(including any Person that has a beneficial interest in this Security) and the Common Stock of the Company issuable upon conversion hereof is entitled to the benefits of a Registration Rights Agreement, dated as of July 6, 2007 executed by the
Company (the “Registration Rights Agreement”). Pursuant to the Registration Rights Agreement, the Company has agreed for the benefit of the Holders from time to time of the Registrable Securities to pay additional interest on this Security
(“Liquidated Damages”) in accordance with the terms of the Registration Rights Agreement. Whenever in this Security there is a reference, in any context, to the payment of the principal of, premium, if any, or interest on, or in
respect of, any Security, such mention shall be deemed to include mention of the payment of Liquidated Damages payable as described in this paragraph to the extent that, in such context, Liquidated Damages are, were or would be payable in respect of
such Security and express mention of the payment of Liquidated Damages (if applicable) in any provisions of this Security shall not be construed as excluding Liquidated Damages in those provisions of this Security where such express mention is not
made. 
 Subject to and upon compliance with the provisions of the Indenture, the Holder of this Security is entitled, at its option, at any
time on or before maturity of the Securities, or in case this Security or a portion hereof is called for redemption, then in respect of this Security or such portion hereof until and including, but (unless the Company defaults in making the payment
due upon redemption or repurchase) not after, the close of business on the Business Day immediately preceding the Redemption Date or Repurchase Date, as the case may be, to convert this Security (or any portion of the principal amount hereof which
is U.S. $1,000 or an integral multiple thereof), at the principal amount hereof, or of such portion, into fully paid and nonassessable shares of Common Stock of the Company at a Conversion Rate of 472.1435 shares of common stock per $1,000 principal
amount of the Securities (or at the current adjusted Conversion Rate if an adjustment has been made as provided in Article 12 of the Indenture) by surrender of this Security, duly endorsed or assigned to the Company or in blank, to the Company
at its office or agency maintained for such purpose, accompanied by the conversion notice hereon executed by the Holder hereof evidencing such Holder’s election to convert this Security, or if less than the entire principal amount hereof is to
be converted, the portion hereof to be converted, and, in case such surrender shall be made during the period from the close of business on any Regular Record Date to the opening of business on the corresponding Interest Payment Date (unless this
Security or the portion hereof being converted has been called for redemption on a Redemption Date within such period between and including such Regular Record Date and such Interest Payment Date), also accompanied by payment in funds acceptable to
the Company of an amount equal to the interest payable on such Interest Payment Date on the principal amount of this Security then being converted. Subject to the aforesaid requirement for payment of interest and, in the case of a conversion after
the close of business on any Regular Record Date and on or before the corresponding Interest Payment Date, to the right of the Holder of this Security (or any Predecessor Security) of record at such Regular Record Date to receive an installment of
interest (even if the Security has been called for redemption on a Redemption Date within such period), no payment or adjustment is to be made on conversion for interest accrued hereon or for dividends on the Common Stock issued on conversion. If a
Holder elects to convert its 










 
Securities in connection with a corporate transaction that would constitute a Non-Stock Change in Control as described in Section 12.01 of the Indenture
at any time on or prior to July 6, 2010, then, in addition to the Common Stock such Holder is entitled to receive upon such conversion, the Company will pay a Make-Whole Premium to such Holders as described in, and subject to the terms of,
Section 12.01 of the Indenture, which Make-Whole Premium shall be due and payable in accordance with Section 12.02 of the Indenture, provided that if the Share Price in such transaction is U.S. $1.83 (subject to adjustment as described
below), no Make-Whole Premium shall be paid by the Company. No fractions of shares or scrip representing fractions of shares will be issued on conversion, but instead of any fractional interest the Company shall pay a cash adjustment as provided in
Article 12 of the Indenture. The Conversion Rate and Conversion Price are subject to adjustment as provided in Article 12 of the Indenture. In addition, the Indenture provides that in case of certain reclassifications, consolidations,
mergers, sales or transfers of assets or other transactions pursuant to which the Common Stock is converted into the right to receive other securities, cash or other property, the conversion privilege shall be modified so that this Security, if then
outstanding, will be convertible thereafter, during the period this Security shall be convertible as specified above, only into the kind and amount of securities, cash and other property receivable upon the transaction by a holder of the number of
shares of Common Stock into which this Security might have been converted immediately prior to such transaction. 
 The Securities (other
than those Securities that have been converted in accordance with the terms of the Indenture) are subject to redemption at the option of the Company upon not less than 30 days’ or more than 60 days’ notice by mail, as a whole or from time
to time in part, at any time after July 6, 2009 at a redemption price of 100% of the principal amount so redeemed, together with accrued interest (including Liquidated Damages, if any) to (but not including) the Redemption Date (subject to the
right of holders of record on the Regular Record Date to receive interest on the related Interest Payment Date); provided, however, that the Securities will not be redeemable during such period unless the Closing Price per share of Common
Stock exceeds 150% of the Conversion Price for at least 20 Trading Days within a period of 30 consecutive Trading Days ending within five Trading Days immediately preceding the aforesaid notice to Holders. Any redemption of Securities must be in
integral multiples of $1,000. 
 If fewer than all of the Securities are to be redeemed, the Trustee shall select the Securities to be
redeemed in principal amounts at maturity of $1,000 or integral multiples thereof by lot, pro rata or by any other method that complies with the requirements of any exchange on which the Securities are listed or quoted and that the Trustee considers
fair and appropriate. If a portion of a Holder’s Securities is selected for partial redemption and that holder converts a portion of those Securities prior to the redemption, the converted portion shall be deemed, solely for purposes of
determining the aggregate principal amount of the Securities to be redeemed by the Company, to be of the portion selected for redemption. 
 In certain circumstances involving a Change in Control, each Holder shall have the right to require the Company to repurchase all or part of its Securities at a repurchase price equal to 100% of the principal amount thereof, together with
accrued and unpaid interest through the Repurchase Date (subject to the right of holders of record on the Regular Record Date to receive interest on the related Interest Payment Date). The repurchase price shall be paid in cash. 
 The Securities do not have the benefit of any sinking fund. 
 In the event of redemption, conversion or repurchase of this Security in part only, a new Security or Securities for the unredeemed, unconverted or unrepurchased portion hereof shall be issued in the name of the
Holder hereof upon the cancellation hereof. 
 If an Event of Default 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 Article 4 of the Indenture. 
 The Indenture permits, with
certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities under 










 
the Indenture at any time by the Company and the Trustee with (or, in the limited circumstances set forth in the Indenture, without) the consent of the
Holders of a majority in aggregate principal amount of the Securities at the time Outstanding. The Indenture also contains provisions permitting the Holders of a majority in aggregate principal amount of the Securities at the time Outstanding, on
behalf of the Holders of all the Securities, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security
shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or
waiver is made upon this Security. 
 No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter
or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of, premium, if any, and interest (including Liquidated Damages) on this Security at the times, place and rate, and in the coin or currency, herein
prescribed or to convert this Security as provided in the Indenture. 
 As provided in the Indenture and subject to certain limitations
therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the Corporate Trust Office duly endorsed by, or accompanied by a written instrument of transfer
in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities, of authorized denominations and for the same aggregate principal
amount, will be issued to the designated transferee or transferees. 
 The Securities are issuable only in registered form without coupons in
denominations of $1,000 and any integral multiple thereof. 
 No service charge shall be made to a Holder for any such registration of
transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. 
 Prior to due presentment of this 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 this Security is registered as the owner
hereof for all purposes and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary. 
 Interest on
this Security will accrue from the most recent date to which interest has been paid, or if no interest has been paid, from July 6, 2007. Interest (including Liquidated Damages) on this Security shall be computed on the basis of a 360-day year
of twelve 30-day months. In the event that any date on which interest (including Liquidated Damages) is payable on the Securities is not a Business Day, then payment of interest payable on such date will be made on the next succeeding day which is a
Business Day (and without any interest or other payment in respect of any such delay). All references to interest in this Security as of any date shall be deemed to include additional interest, if any, accrued or payable as of such date as provided
in the Indenture or this Security. 
 All terms used in this Security which are defined in the Indenture shall have the meanings assigned to
them in the Indenture. 
 THE INDENTURE AND THIS SECURITY SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW
YORK WITHOUT REGARD TO CONFLICT OF LAWS PRINCIPLES.
