certificates, statements, opinions or other instruments under this Indenture, they may, but need not, be consolidated and form one instrument. 
 Section 1.4 Acts of Holders. 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 of all series or one or
more series, as the case may be, 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. If Securities of a series are issuable as Bearer
Securities, any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by Holders of Securities of such series may, alternatively, be embodied in and evidenced by the record
of Holders of Securities of such series voting in favor thereof, either in person or by proxies duly appointed in writing, at any meeting of Holders of Securities of such series duly called and held in accordance with the provisions of Article
Fifteen, or a combination of such instruments and any such record. Except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments or record or both are delivered to the Trustee and, where it is
hereby expressly required, to the Company. Such instrument or instruments and any such record (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Holders signing such instrument or
instruments or so voting at any such meeting. 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, if made in the manner provided in this Section. The record of any meeting of Holders of Securities shall be proved in the manner provided in Section 15.6.

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 authority. The fact and date of the execution of any such instrument or writing, or the authority of the Person
executing the same, may also be proved in any other manner that the Trustee deems sufficient.

of Registered Securities held by any Person, and the date of holding the same, shall be proved by the Security Register. 
 (3) The principal
amount and serial numbers of Bearer Securities held by any Person, and the date of holding the same, may be proved by (i) the production of such Bearer Securities or by a certificate executed, as depositary, by any trust company, bank, banker
or other depositary, wherever situated, if such certificate shall be deemed by the Trustee to be satisfactory, showing that at the date therein mentioned such Person had on deposit with such depositary, or exhibited to it, the Bearer Securities
therein 

  

 - 13 - 

 
described; or (ii) such facts as may be proved by the certificate or affidavit of the Person holding such Bearer Securities, if such certificate or
affidavit is deemed by the Trustee to be satisfactory. The Trustee or the Company may assume that such ownership of any Bearer Security continues until (1) another certificate or affidavit bearing a later date issued in respect of the same
Bearer Security is produced, or (2) such Bearer Security is produced to the Trustee by some other Person, or (3) such Bearer Security is surrendered in exchange for a Registered Security, or (4) such Bearer Security is no longer
Outstanding. The principal amount and serial numbers of Bearer Securities held by any Person, and the date of holding the same, may also be proved in any other manner that the Trustee deems sufficient. 
 (4) If the Company shall solicit from the Holders of Registered Securities 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 give such request, demand, authorization, direction, notice, consent, waiver or other Act, but
the Company shall have no obligation to do so. 
 Notwithstanding TIA Section 3.16(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 given before or after such record date, but only the Holders of record at the close of business on such record date shall be
deemed to be Holders for the purposes of determining whether Holders of the requisite proportion of Outstanding Securities have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other
Act, and for that purpose the Outstanding Securities shall be computed as of such record date; provided that no such authorization, agreement or consent by the Holders on such record date shall be deemed effective unless it shall become effective
pursuant to the provisions of this Indenture not later than eleven months after the record date. 
 (5) 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 Authenticating Agent, or the Company in reliance thereon, whether or not notation of such action is made upon such
Security. 
 Section 1.5 Notices, etc. to Trustee or the Company. Any request, demand, authorization, direction, notice, consent,
waiver or Act of Holders or other documents provided or permitted by this Indenture to be made upon, given or furnished to, or filed with, 
  

 - 14 - 

 (1) the Trustee by any Holder or by the Company shall be sufficient for every purpose hereunder (unless
otherwise herein expressly provided) if made, given, furnished or filed in writing to or with the Trustee at its Corporate Trust Office, Attention: Corporate Trust Administration, or 
 (2) 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 mailed, first-class postage prepaid or by overnight delivery service, to the Company addressed to it at the address of the Company’s principal office specified in the first paragraph of this Indenture, to the attention of its
General Counsel, or at any other address previously furnished in writing to the Trustee by the Company. 
 Section 1.6 Notice to
Holders; Waiver. Except as otherwise expressly provided herein or otherwise specified with respect to any series of Securities pursuant to Section 3.1, where this Indenture provides for notice of any event to Holders of Registered
Securities by the Company or the Trustee, such notice shall be sufficiently given 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. In any case where notice to Holders of Registered Securities 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 of Registered Securities or the sufficiency of any notice to Holders of Bearer Securities given as provided. 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. 
 In case, by reason of the suspension of or irregularities in regular mail service or by reason of any other cause, it shall be impractical to mail notice of any event to Holders of Registered Securities when such
notice is required to be given pursuant to any provision of this Indenture, then any manner of giving such notice as shall be satisfactory to the Trustee shall be deemed to be sufficient giving of such notice for every purpose hereunder. 

Except as otherwise expressly provided herein or otherwise specified with respect to any Securities pursuant to Section 3.1, where this Indenture
provides for notice to Holders of Bearer Securities of any event, such notice shall be sufficiently given to Holders of Bearer Securities if published in an Authorized Newspaper in The City of New York and in such other city or cities as may be
specified in such Securities on a Business Day at least twice, the first such publication to be not earlier than the earliest date, and not later than the latest date, prescribed for the giving of such notice. Any such notice shall be deemed to have
been given on the date of such publication or, if published more than once, on the date of the first such publication. 
 If by reason of the
suspension of publication of any Authorized Newspaper or Authorized Newspapers or by reason of any other cause, it shall be impracticable to publish any notice to Holders of Bearer Securities as provided above, then such 

  

 - 15 - 

 
notification to Holders of Bearer Securities as shall be given with the approval of the Trustee shall constitute sufficient notice to such Holders for every
purpose hereunder. Neither the failure to give notice by publication to Holders of Bearer Securities as provided above, nor any defect in any notice so published, shall affect the sufficiency of such notice with respect to other Holders of Bearer
Securities or the sufficiency of any notice to Holders of Registered Securities given as provided herein. 
 Any request, demand,
authorization, direction, notice, consent or waiver 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.

Contents are for convenience only and shall not affect the construction hereof. 
 Section 1.8 Successors and Assigns. All
covenants and agreements in this Indenture by the Company shall bind its successors and assigns, whether so expressed or not.

any way be affected or impaired thereby.

coupons, express or implied, shall give to any Person, other than the parties hereto, any Authenticating Agent, any Paying Agent, any Securities Registrar and their respective successors hereunder and the Holders of Securities or coupons, any
benefit or any legal or equitable right, remedy or claim under this Indenture.

coupon other than a provision in the Securities of any series which specifically states that such

provision shall apply in lieu of this Section), payment of principal (or premium, if any) or interest, if any, need not be made at 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 Repayment Date, sinking fund payment date, or at the Stated Maturity or
Maturity, as the case may be; provided that no interest shall accrue on the amount so payable for the period from and after such Interest Payment Date, Redemption Date, Repayment Date, sinking fund payment date, Stated Maturity or Maturity, as the
case may be.

 Section 2.3 Securities Issuable in Global Form. If Securities of or within a series are
issuable in global form, as specified as contemplated by Section 3.1, then, notwithstanding clause (8) of Section 3.1, any such Security shall represent such of the Outstanding Securities of such series as shall be specified therein
and may provide that it shall represent the aggregate amount of Outstanding Securities of such series from time to time endorsed thereon and that the aggregate amount of Outstanding Securities of such series represented thereby may from time to time
be increased or decreased to reflect exchanges. Any endorsement of 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 3.3 or Section 3.4, as applicable. Subject to the provisions of Section 3.3
and Section 3.4, as applicable, the Trustee shall deliver any Security in permanent 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 3.3 or Section 3.4 has been, or simultaneously is, delivered, any instructions by the Company with respect to endorsement or delivery of a Security in global form shall be in writing but need not comply with Section 1.2 and
need not be accompanied by an Opinion of Counsel. 
 The provisions of the last sentence of Section 3.3 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 1.2
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 3.3. 
 Notwithstanding any provisions of Section 3.7 to the contrary, unless otherwise specified as contemplated by Section 3.1, payment of principal
of (and premium, if any) and interest, if any, on any Security in permanent global form shall be made to the Person or Persons specified therein. 
 Notwithstanding the provisions of Section 3.9 and except as provided in the preceding paragraph, the Company, the Trustee and any agent of the Company and the Trustee shall treat as the Holder of such principal amount of Outstanding
Securities represented by a permanent global Security (i), in the case of a permanent global Security in registered form, the Holder of such permanent global Security in registered form, or (ii) in the case of a permanent global Security in
bearer form, Euroclear or Clearstream.

will pay Additional Amounts as contemplated by Section 10.8 on the Securities of the series to any Holder who is not a United States person (including any modification to the definition of such term) in respect of any tax, assessment or

 - 23 - 

 Section 3.3 Execution, Authentication, Delivery and Dating. The Securities and any coupons
appertaining thereto shall be executed on behalf of the Company by its Chairman, its President or a Vice President. The signature of any of these officers on the Securities or coupons may be the manual or facsimile signatures of the present or any
future such authorized officer and may be imprinted or otherwise reproduced on the Securities. 
 Securities or coupons bearing the manual or
facsimile signatures of individuals who were at any time the proper officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of
such Securities or did not hold such offices at the date of such Securities or coupons. 
 At any time and from time to time after the
execution and delivery of this Indenture, the Company may deliver Securities of any series together with any coupons appertaining thereto, 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 such Company Order shall authenticate and deliver such Securities; provided, however, that, in connection with its original issuance, no Bearer Security shall be
mailed or otherwise delivered to any location in the United States; and provided further that, unless otherwise specified with respect to any series of Securities pursuant to Section 3.1, a Bearer Security may be delivered in connection with
its original issuance only if the Person entitled to receive such Bearer Security shall have furnished a certificate substantially in the form set forth in Exhibit A-1 to this Indenture, dated no earlier than 15 days prior to the earlier of the date
on which such Bearer Security is delivered and the date on which any temporary Security first becomes exchangeable for such Bearer Security in accordance with the terms of such temporary Security and this Indenture. If any Security shall be
represented by a permanent global Bearer Security, then, for purposes of this Section and Section 3.4, the notation of a beneficial owner’s interest therein upon original issuance of such Security or upon exchange of a portion of a
temporary global Security shall be deemed to be delivery in connection with its original issuance of such beneficial owner’s interest in such permanent global Security. Except as permitted by Section 3.6, the Trustee shall not authenticate
and deliver any Bearer Security unless all appurtenant coupons for interest then matured have been detached and cancelled. If not all the Securities of any series are to be issued at one time and if the Board Resolution, and the Officer’s
Certificate pursuant to a Board Resolution or supplemental indenture establishing such series shall so permit, such Company Order may set forth procedures acceptable to the Trustee for the issuance of such Securities and determining terms of
particular Securities of such series such as interest rate, maturity, date of issuance and date from which interest shall accrue. 
 In
authenticating such Securities, and accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee shall be entitled to receive, and shall be fully protected in relying upon: 
 (a) the Board Resolution and the Officers’ Certificate or supplemental indenture, as applicable, relating thereto and, if applicable, an appropriate
record of any action taken pursuant to such resolution, certificate or supplemental indenture, certified by the Secretary or an Assistant Secretary of the Company; 
  

 - 24 - 

 (b) an Opinion of Counsel stating in effect (subject to customary exceptions): 
 (1) that the form or forms of such Securities to be endorsed thereon and any coupons have been established in conformity with the
provisions of this Indenture; 
 (2) that the terms of such Securities and any coupons have been established in conformity
with the provisions of this Indenture; 
 (3) that such Securities and any coupons appertaining thereto, when completed by
appropriate insertions and executed and delivered by the Company to the Trustee for authentication in accordance with this Indenture, and authenticated and delivered by the Trustee in accordance with this Indenture and issued by the Company in the
manner and subject to any conditions specified in such Opinion of Counsel, will be the legal, valid and binding obligations of the Company enforceable in accordance with their terms, subject to the effect of any applicable bankruptcy, insolvency,
reorganization, moratorium and other similar laws affecting creditors’ rights generally (including on all laws relating to fraudulent transfers), to general principles of equity; 
 (4) that all laws and requirements in respect of the execution and delivery by the Company of such Securities, any coupons and of the
supplemental indentures, if any, have been complied with and that authentication and delivery of such Securities and any coupons and the execution and delivery of the supplemental indenture, if any, by the Trustee will not violate the terms of the
Indenture; 
 (5) that the Company has the corporate power to issue such Securities and any coupons, and has duly taken all
necessary corporate action with respect to such issuance; and 
 (6) that the issuance of such Securities and any coupons will
not contravene the articles of incorporation or by-laws of the Company or result in any violation of any of the terms or provisions of any law or regulation or of any indenture, mortgage or other agreement known to such Counsel by which the Company
is bound; and 
 (c) an Officers’ Certificate of the Company as to the absence of any event that is, or after notice or lapse of time or
both would become, an Event of Default. 
  

 - 25 - 

 The Trustee shall not be required to authenticate and deliver any such Securities if the issue of such
Securities pursuant to this Indenture will affect the Trustee’s own rights, duties or immunities under the Securities and this Indenture or otherwise in a manner which is not reasonably acceptable to the Trustee. 
 Each Registered Security shall be dated the date of its authentication and each Bearer Security shall be dated as of the date specified as contemplated
by Section 3.1. 
 No Security or coupon shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose
unless there appears on such Security a certificate of authentication substantially in the form provided for herein duly executed by the Trustee by manual signature of an authorized officer, 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 3.10 together with a written statement (which need not comply with Section 1.2 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 never to have been authenticated and delivered hereunder and shall never be entitled to the benefits of this Indenture. 
 Section 3.4 Temporary Securities. Pending the preparation of definitive Securities of any series, the Company may execute, and upon Company
Order the Trustee shall authenticate and deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu
of which they are issued and in registered form or, if authorized, in bearer form with one or more coupons or without coupons, and with such appropriate insertions, omissions, substitutions and other variations as conclusively the officers executing
such Securities or coupons may determine, as conclusively evidenced by their execution of such Securities or coupons, as the case may be. Such temporary Securities may be in global form. 
 Except in the case of temporary Securities in global form (which shall be exchanged in accordance with the provisions of the following paragraphs), if
temporary Securities of any series are issued, the Company will cause definitive Securities of that series to be prepared without unreasonable delay. After the preparation of definitive Securities of such series, the temporary Securities of such
series shall be exchangeable for definitive Securities of such series upon surrender of the temporary Securities of such series at the office or agency of the Company in a Place of Payment for that series, without charge to the Holder. Upon
surrender for cancellation of any one or more temporary Securities of any series (accompanied by any unmatured coupons appertaining thereto), the Company shall execute and upon receipt of a Company Order the Trustee shall authenticate and deliver in
exchange therefor a like principal amount of definitive Securities of the same series and of like tenor of authorized denominations; provided, 

  

 - 26 - 

 
however, that no definitive Bearer Security shall be delivered in exchange for a temporary Registered Security; and provided further that a definitive Bearer
Security shall be delivered in exchange for a temporary Bearer Security only in compliance with the conditions set forth in Section 3.3. Until so exchanged the temporary Securities of any series shall in all respects be entitled to the same
benefits under this Indenture as definitive Securities of such series. If temporary Securities of any series are issued in global form, any such temporary global Security shall, unless otherwise provided therein, be delivered to the London office of
a depositary or common depositary (the “Common Depositary”), for the benefit of Euroclear and Clearstream, for credit to the respective accounts of the beneficial owners of such Securities (or to such other accounts as they may direct).

 Without unnecessary delay but in any event not later than the date specified in, or determined pursuant to the terms of, any such
temporary global Security (the “Exchange Date”), the Company shall deliver to the Trustee definitive Securities, in aggregate principal amount equal to the principal amount of such temporary global Security, executed by the Company. On or
after the Exchange Date such temporary global Security shall be surrendered by the Common Depositary to the Trustee, as the Company’s agent for such purpose, to be exchanged, in whole or from time to time in part, for definitive Securities
without charge and upon receipt of a Company Order the Trustee shall authenticate and deliver, in exchange for each portion of such temporary global Security, an equal aggregate principal amount of definitive Securities of the same series of
authorized denominations and of like tenor as the portion of such temporary global Security to be exchanged. The definitive Securities to be delivered in exchange for any such temporary global Security shall be in bearer form, registered form,
permanent global bearer form or permanent global registered form, or any combination thereof, as specified as contemplated by Section 3.1, and, if any combination thereof is so specified, as requested by the beneficial owner thereof; provided,
however, that, unless otherwise specified in such temporary global Security, upon such presentation by the Common Depositary, such temporary global Security is accompanied by a certificate dated the Exchange Date or a subsequent date and signed by
Euroclear as to the portion of such temporary global Security held for its account then to be exchanged and a certificate dated the Exchange Date or a subsequent date and signed by Clearstream as to the portion of such temporary global Security held
for its account then to be exchanged, each substantially in the form set forth in Exhibit A-2 to this Indenture (or in such other form as may be established pursuant to Section 3.1); and provided further that definitive Bearer Securities shall
be delivered in exchange for a portion of a temporary global Security only in compliance with the requirements of Section 3.3. Definitive Securities in bearer form to be delivered in exchange for any portion of a temporary global Security shall
be delivered only outside the United States. 
 Until exchanged in full as hereinabove provided, the temporary Securities of any series shall
in all respects be entitled to the same benefits under this Indenture as definitive Securities of the same series and of like tenor authenticated and delivered hereunder, except that, unless otherwise specified as contemplated by Section 3.1,
interest payable on a temporary global Security on an Interest Payment Date for Securities of such series occurring prior to the applicable Exchange Date shall be payable 

  

 - 27 - 

 
to Euroclear and Clearstream on such Interest Payment Date upon delivery by Euroclear and Clearstream to the Trustee or the applicable Paying Agent of a
certificate or certificates substantially in the form set forth in Exhibit A-2 to this Indenture (or in such other form as may be established pursuant to Section 3.1), for credit without further interest thereon on or after such Interest
Payment Date to the respective accounts of the Persons who are the beneficial owners of such temporary global Security on such Interest Payment Date and who have each delivered to Euroclear or Clearstream, as the case may be, a certificate dated no
earlier than 15 days prior to the Interest Payment Date occurring prior to such Exchange Date substantially in the form set forth in Exhibit A-1 to this Indenture (or in such other form as may be established pursuant to Section 3.1).
Notwithstanding anything to the contrary herein contained, the certifications made pursuant to this paragraph shall satisfy the certification requirements of the preceding two paragraphs of this Section and of the third paragraph of Section 3.3
of this Indenture and the interests of the Persons who are the beneficial owners of the temporary global Security with respect to which such certification was made will be exchanged for definitive Securities of the same series and of like tenor on
the Exchange Date or the date of certification if such date occurs after the Exchange Date, without further act or deed by such beneficial owners. Except as otherwise provided in this paragraph, no payments of principal (or premium, if any) or
interest, if any, owing with respect to a beneficial interest in a temporary global Security will be made unless and until such interest in such temporary global Security shall have been exchanged for an interest in a definitive Security. Any
interest so received by Euroclear and Clearstream and not paid as herein provided shall be returned to the Trustee or the applicable Paying Agent immediately prior to the expiration of two years after such Interest Payment Date in order to be repaid
to the Company in accordance with (but otherwise subject to) Section 10.3. 
 Section 3.5 Registration, Registration of Transfer
and Exchange. The Company and the Trustee shall cause to be kept at the Corporate Trust Office of the Trustee a register for each series of Securities (the registers maintained in the Corporate Trust Office of the Trustee and in any other office
or agency of the Company in a Place of Payment being herein sometimes collectively referred to as the “Security Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration
of Registered Securities and of transfers of Registered Securities; provided, however, that there shall be only one Security Register per series of Securities. The Security Register shall be in written form or any other form capable of being
converted into written form within a reasonable time. At all reasonable times, the Security Register shall be open to inspection by the Trustee. The Trustee is hereby initially appointed as security registrar (the “Security Registrar”) for
the purpose of registering Registered Securities and transfers of Registered Securities as herein provided and for facilitating exchanges of temporary global Securities for permanent global Securities or definitive Securities, or both, or of
permanent global Securities for definitive Securities, as herein provided. 
 Upon surrender for registration of transfer of any Registered
Security of any series at the office or agency in a Place of Payment for that series, the Company shall execute, and upon receipt of a Company Order the Trustee shall authenticate and deliver, in the name of the designated transferee, one or more
new Registered Securities of the same series, of any authorized denominations and of a like aggregate principal amount and tenor. 
  

 - 28 - 

 At the option of the Holder, Registered Securities of any series may be exchanged for other Registered
Securities of the same series, of any authorized denomination and of a like aggregate principal amount, upon surrender of the Registered Securities to be exchanged at such office or agency. Whenever any Registered Securities are so surrendered for
exchange, the Company shall execute, and upon receipt of a Company Order the Trustee shall authenticate and deliver, the Registered Securities which the Holder making the exchange is entitled to receive. Unless otherwise specified with respect to
any series of Securities as contemplated by Section 3.1 or this Section 3.5, Bearer Securities may not be issued in exchange for Registered Securities. 
 If (but only if) expressly permitted in or pursuant to the applicable Board Resolution and (subject to Section 3.3) set forth in the applicable Officer’s Certificate, or in any indenture supplemental hereto,
delivered as contemplated by Section 3.1, at the option of the Holder, Bearer Securities of any series may be exchanged for Registered Securities of the same series of any authorized denomination and of a like aggregate principal amount and
tenor, upon surrender of the Bearer Securities to be exchanged at any such office or agency, with all unmatured coupons and all matured coupons in default thereto appertaining. If the Holder of a Bearer Security is unable to produce any such
unmatured coupon or coupons or matured coupon or coupons in default, any such permitted exchange may be effected if the Bearer Securities are accompanied by payment in funds acceptable to the Company in an amount equal to the face amount of such
missing coupon or coupons, or the surrender of such missing coupon or coupons may be waived by the Company and the Trustee if there is furnished to them such security or indemnity as they may require to save each of them and any Paying Agent
harmless. If thereafter the Holder of such Security shall surrender to any Paying Agent any such missing coupon in respect of which such a payment shall have been made, such Holder shall be entitled to receive the amount of such payment; provided,
however, that, except as otherwise provided in Section 10.2, interest represented by coupons shall be payable only upon presentation and surrender of those coupons at an office or agency located outside the United States. Notwithstanding the
foregoing, in case a Bearer Security of any series is surrendered at any such office or agency in a permitted exchange for a Registered Security of the same series and like tenor after the close of business at such office or agency 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, such Bearer Security shall be surrendered without the coupon relating to such Interest Payment Date or proposed date for payment, as the case may be, and interest or Defaulted Interest, as the case may be, will not be
payable on such Interest Payment Date or proposed date for payment, as the case may be, in respect of the Registered Security issued in exchange for such Bearer Security, but will be payable only to the Holder of such coupon when due in accordance
with the provisions of this Indenture. 
  

 - 29 - 

 Whenever any Securities are so surrendered for exchange, the Company shall execute, and upon receipt of a
Company Order the Trustee shall authenticate and deliver, the Securities that the Holder making the exchange is entitled to receive. 
 Notwithstanding the foregoing, except as otherwise specified as contemplated by Section 3.1, any permanent global Security shall be exchangeable only as provided in this paragraph. If any beneficial owner of an interest in a permanent
global Security is entitled to exchange such interest for Securities of such series and of like tenor and principal amount of another authorized form and denomination, as specified as contemplated by Section 3.1 and provided that any applicable
notice provided in the permanent global Security shall have been given, then without unnecessary delay but in any event not later than the earliest date on which such interest may be so exchanged, the Company shall deliver to the Trustee definitive
Securities of that series in aggregate principal amount equal to the principal amount of such beneficial owner’s interest in such permanent global Security, executed by the Company. On or after the earliest date on which such interests may be
so exchanged, such permanent global Security shall be surrendered by the Common Depositary or such other depositary as shall be specified in the Company Order with respect thereto to the Trustee, as the Company’s agent for such purpose, to be
exchanged, in whole or from time to time in part, for definitive Securities without charge, and upon receipt of such Company Order the Trustee shall authenticate and deliver, in exchange for each portion of such permanent global Security, an equal
aggregate principal amount of definitive Securities of the same series of authorized denominations and of like tenor as the portion of such permanent global Security to be exchanged which, unless the Securities of the series are not issuable both as
Bearer Securities and as Registered Securities, as specified as contemplated by Section 3.1, shall be in the form of Bearer Securities or Registered Securities, or any combination thereof, as shall be specified by the beneficial owner thereof;
provided, however, that no such exchanges may occur during a period beginning at the opening of business 15 days before any selection of Securities to be redeemed and ending on the relevant Redemption Date if the Security for which exchange is
requested may be among those selected for redemption; and provided, further, that no Bearer Security delivered in exchange for a portion of a permanent global Security shall be mailed or otherwise delivered to any location in the United States. If a
Registered Security is issued in exchange for any portion of a permanent 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, will not be payable on such Interest Payment Date or proposed date for payment, as the case may be, in respect of such Registered 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 permanent 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. 
  

 - 30 - 

 Every Registered Security presented or surrendered for registration of transfer or for exchange 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. 
 No service charge shall be made 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 3.4, 9.6, 11.7 or 13.5 not
involving any transfer. 
 If at any time the Depositary for any permanent global Registered Securities of any series notifies the Company
that it is unwilling or unable to continue as Depositary for such permanent global Registered Securities or if at any time the Depositary for such permanent global Registered Securities shall no longer be eligible under applicable law, the Company
shall appoint a successor Depositary eligible under applicable law with respect to such permanent global Registered Securities. If a successor Depositary eligible under applicable law for such Registered Global Securities is not appointed by the
Company within 90 days after the Company receives such notice or becomes aware of such ineligibility, the Company will execute, and the Trustee, upon receipt a Company Order for the authentication and delivery of definitive Registered Securities of
such series and tenor, will authenticate and deliver such definitive Registered Securities of such series and tenor, in any authorized denominations, in an aggregate principal amount equal to the principal amount of such permanent global Registered
Securities, in exchange for such permanent global Registered Securities. 
 The Company may at any time and in its sole discretion determine
that any permanent global Registered Securities of any series shall no longer be maintained in global form. In such event the Company will execute, and the Trustee, upon receipt of a Company Order for the authentication and delivery of definitive
Registered Securities of such series and tenor, will authenticate and deliver, definitive Registered Securities of such series and tenor in any authorized denominations, in an aggregate principal amount equal to the principal amount of such
permanent global Registered Securities, in exchange for such permanent global Registered Securities. 
 The Company shall not be required
(i) to issue, register the transfer of or exchange Securities of any series during a period beginning at the opening of business 15 days before the day of the selection for redemption of Securities of that series under Sections 11.3 or 12.3 and
ending at the close of business on (A) if Securities of the series are issuable only as Registered Securities, the day of the mailing of the relevant notice of redemption and (B) if Securities of the series are issuable as Bearer
Securities, the day of the first publication of the relevant notice of redemption or, if Securities of the series are also issuable as Registered Securities and there is no publication, the mailing of the relevant notice of redemption, or
(ii) to register the transfer of or exchange any Registered Security so selected for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part, or (iii) to exchange any 

  

 - 31 - 

 
Bearer Security so selected for redemption except that such a Bearer Security may be exchanged for a Registered Security of that series and like tenor;
provided that such Registered Security shall be simultaneously surrendered for redemption, or (iv) to issue, register the transfer of or exchange any Security which has been surrendered for repayment at the option of the Holder, except the
portion, if any, of such Security not to be so repaid. 
 The Trustee shall have no obligation or duty to monitor, determine or inquire as to
compliance with any restrictions on transfer that may be imposed under this Indenture with respect to the Securities of any series pursuant to the terms thereof established as contemplated by Section 3.1 or under applicable law with respect to
any transfer of any interest in any such Security (including any transfers between or among any depositary (including any Depositary or Common Depositary), or its nominee, as a Holder of a Security issued in global form, any participants in such
depositary or owners or holders of beneficial interests in any such global Security) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required
by, the terms of such Securities if and as may be so established in respect of such Securities, and to examine the same to determine substantial compliance as to form with the express requirements thereof. Neither the Trustee nor any agent of the
Trustee shall have any responsibility for actions taken or not taken by the Depositary. 
 Section 3.6 Mutilated, Destroyed, Lost and
Stolen Securities. If any mutilated Security or a Security with a mutilated coupon appertaining to it is surrendered to the Trustee, the Company shall execute and upon receipt of a Company Order the Trustee shall authenticate and deliver in
exchange therefor a new Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously Outstanding, with coupons corresponding to the coupons, if any, appertaining to the surrendered Security, or, in
case any such mutilated Security or coupon has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Security, with coupons corresponding to the coupons, if any, appertaining to the surrendered
Security, pay such Security or coupon. 
 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 or coupon 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 or coupon has been acquired by a bona fide purchaser, the Company shall execute and upon Company Order the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security or in
exchange for the Security to which a destroyed, lost or stolen coupon appertains (with all appurtenant coupons not destroyed, lost or stolen), a new Security of the same series and of like tenor and principal amount and bearing a number not
contemporaneously Outstanding with coupons corresponding to the coupons, if any, appertaining to such destroyed, lost or stolen Security or to the Security to which such destroyed, lost or stolen coupon appertains. Notwithstanding the provisions of
the previous two paragraphs, in case any such mutilated, destroyed, lost or stolen Security or coupon has become or is about to become due and payable, the 

  

 - 32 - 

 
Company in its discretion may, instead of issuing a new Security, with coupons corresponding to the coupons, if any, appertaining to such mutilated,
destroyed, lost or stolen Security or to the Security to which such mutilated, destroyed, lost or stolen coupon appertains, pay such Security or coupon; provided, however, that payment of principal of (and premium, if any) and interest, if any, on
Bearer Securities shall, except as otherwise provided in Section 10.2, be payable only at an office or agency located outside the United States and, unless otherwise specified as contemplated by Section 3.1, any interest on Bearer
Securities shall be payable only upon presentation and surrender of the coupons appertaining thereto. 
 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 of any series with its coupons, if any, issued pursuant to this Section in lieu of any mutilated,
destroyed, lost or stolen Security, or in exchange for a Security to which a mutilated, destroyed, lost or stolen coupon appertains, shall constitute an original additional contractual obligation of the Company and whether or not the mutilated,
destroyed, lost or stolen Security and its coupons, if any, or the mutilated, destroyed, lost or stolen coupon 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 of that series and their coupons, if any, 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 or coupons. 
 Section 3.7 Payment of Interest; Interest Rights Preserved; Optional Interest Reset. (a) Unless otherwise provided as contemplated by
Section 3.1 with respect to any series of Securities, interest, if any, on any Registered Security which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name such
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 10.2; provided, however,
that each installment of interest, if any, on any Registered 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 3.9, to the address of such Person as it appears on the Security Register or (ii) transfer to an account located in the United States maintained by the payee. If the Person entitled to such payment delivers appropriate wire
instructions to the Trustee within 15 Business Days of the Interest Payment Date, the Company will pay such amount via wire transfer. 
 Unless otherwise provided as contemplated by Section 3.1 with respect to the Securities of any series, payment of interest, if any, may be made, in the case of a Bearer Security, by transfer to an account located outside the United
States maintained by the payee. Any interest on any Registered Security of any series which is payable, but is not 

  

 - 33 - 

 
punctually paid or duly provided for, on any Interest Payment Date shall forthwith cease to be payable to the Holder on the relevant Regular Record Date by
virtue of having been such Holder, and such defaulted interest and, if applicable, interest on such defaulted interest (to the extent lawful) at the rate specified in the Securities of such series (such defaulted interest and, if applicable,
interest thereon herein collectively called “Defaulted Interest”) shall be paid by the Company, at its election in each case, as provided in clause (1) or (2) below: 
 (1) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Registered Securities of such series (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 Registered Security of such series and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money in the Currency in which the
Securities of such series are payable (except as otherwise specified pursuant to Section 3.1 for the Securities of such series and except, if applicable, as provided in Sections 3.12(b), 3.12(d) and 3.12(e)) 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 Trustee shall fix a Special Record Date for the payment of such Defaulted Interest that shall be not more than 15 days and not less than 10 days prior to the date
of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company,
shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be given in the manner provided in Section 1.6, not less than 10 days prior to such Special Record Date. Notice of the proposed
payment of such Defaulted Interest and the Special Record Date therefor having been so given, such Defaulted Interest shall be paid to the Persons in whose name the Registered Securities of such series (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 (2). 
 (2) The Company may make payment of any Defaulted Interest on the Registered Securities of any series 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. 
 (b) The provisions of this Section 3.7(b) may be made applicable to any series of Securities pursuant to Section 3.1 (with such modifications,
additions or substitutions as may be specified pursuant to such Section 3.1). The interest rate (or the spread or spread multiplier used to calculate such interest rate, if applicable) on any Security of such series may be reset by the Company
on the date or dates specified on the 

  

 - 34 - 

 
face of such Security (each an “Optional Reset Date”). The Company may exercise such option with respect to such Security by notifying the Trustee
of such exercise (and of the information described in the immediately succeeding sentence) at least 50 but not more than 60 days prior to an Optional Reset Date for such Security. Not later than 40 days prior to each Optional Reset Date, the Trustee
shall transmit, in the manner provided for in Section 1.6, to the Holder of any such Security a notice (the “Reset Notice”) indicating whether the Company has elected to reset the interest rate (or the spread or spread multiplier used
to calculate such interest rate, if applicable), and if so (i) such new interest rate (or such new spread or spread multiplier, if applicable) and (ii) the provisions, if any, for redemption during the period from such Optional Reset Date
to the next Optional Reset Date or if there is no such next Optional Reset Date, to the date of Maturity of such Security (each such period a “Subsequent Interest Period”), including the date or dates on which or the period or periods
during which and the price or prices at which such redemption may occur during the Subsequent Interest Period. 
 Notwithstanding the
foregoing, not later than 20 days prior to the Optional Reset Date, the Company may, at its option, revoke the interest rate (or the spread or spread multiplier used to calculate such interest rate, if applicable) provided for in the Reset Notice
and establish an interest rate (or a spread or spread multiplier used to calculate such interest rate, if applicable) that is higher than the interest rate (or the spread or spread multiplier, if applicable) provided for in the Reset Notice, for the
Subsequent Interest Period by causing the Trustee to transmit, in the manner provided for in Section 1.6, notice of such higher interest rate (or such higher spread or spread multiplier, if applicable) to the Holder of such Security. Such
notice shall be irrevocable. All Securities with respect to which the interest rate (or the spread or spread multiplier used to calculate such interest rate, if applicable) is reset on an Optional Reset Date, and with respect to which the Holders of
such Securities have not tendered such Securities for repayment (or have validly revoked any such tender) pursuant to the next succeeding paragraph, will bear such higher interest rate (or such higher spread or spread multiplier, if applicable).

 The Holder of any such Security will have the option to elect repayment by the Company of the principal of such Security on each Optional
Reset Date at a price equal to the principal amount thereof plus interest accrued to such Optional Reset Date. In order to obtain repayment on an Optional Reset Date, the Holder must follow the procedures set forth in Article Thirteen for repayment
at the option of Holders except that the period for delivery or notification to the Trustee shall be at least 25 but not more than 35 days prior to such Optional Reset Date and except that, if the Holder has tendered any Security for repayment
pursuant to the Reset Notice, the Holder may, by written notice to the Trustee, revoke such tender or repayment until the close of business on the tenth day before such Optional Reset Date. 
 Subject to the foregoing provisions of this Section and Section 3.5, 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. 
  

 - 35 - 

 Section 3.8 Optional Extension of Maturity. The provisions of this Section 3.8 may be
made applicable to any series of Securities pursuant to Section 3.1 (with such modifications, additions or substitutions as may be specified pursuant to such Section 3.1). The Stated Maturity of any Security of such series may be extended
at the option of the Company for the period or periods specified on the face of such Security (each an “Extension Period”) up to but not beyond the final maturity date set forth on the face of such Security. The Company may exercise such
option with respect to any Security by notifying the Trustee of such exercise (and of the information described in the immediately succeeding sentence) at least 50 but not more than 60 days prior to the Stated Maturity of such Security in effect
prior to the exercise of such option (the “Original Stated Maturity”). If the Company exercises such option, the Trustee shall transmit, in the manner provided for in Section 1.6, to the Holder of such Security not later than 40 days
prior to the Original Stated Maturity a notice (the “Extension Notice”) prepared by the Company indicating (i) the election of the Company to extend the Stated Maturity, (ii) the new Stated Maturity, (iii) the interest rate,
if any, applicable to the Extension Period and (iv) the provisions, if any, for redemption during such Extension Period. Upon the Trustee’s transmittal of the Extension Notice, the Stated Maturity of such Security shall be extended
automatically and, except as modified by the Extension Notice and as described in the next paragraph, such Security will have the same terms as prior to the transmittal of such Extension Notice. 
 Notwithstanding the foregoing, not later than 20 days before the Original Stated Maturity of such Security, the Company may, at its option, revoke the
interest rate provided for in the Extension Notice and establish a higher interest rate for the Extension Period by causing the Trustee to transmit, in the manner provided for in Section 1.6, notice of such higher interest rate to the Holder of
such Security. Such notice shall be irrevocable. All Securities with respect to which the Stated Maturity is extended will bear such higher interest rate. 
 If the Company extends the Stated Maturity of any Security, the Holder will have the option to elect repayment of such Security by the Company on the Original Stated Maturity at a price equal to the principal amount
thereof, plus interest accrued to such date. In order to obtain repayment on the Original Stated Maturity once the Company has extended the Stated Maturity thereof, the Holder must follow the procedures set forth in Article Thirteen for repayment at
the option of Holders, except that the period for delivery or notification to the Trustee shall be at least 25 but not more than 35 days prior to the Original Stated Maturity and except that, if the Holder has tendered any Security for repayment
pursuant to an Extension Notice, the Holder may by written notice to the Trustee revoke such tender for repayment until the close of business on the tenth day before the Original Stated Maturity. 
 Section 3.9 Persons Deemed Owners. Prior to due presentment of a Registered 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 Registered Security is registered as the absolute owner of such Registered Security for the purpose of receiving payment of principal of (and premium, if any) and
(subject to Sections 3.5 and 3.7) interest, if any, on such Security and for all other purposes whatsoever, whether or not such Security be overdue, and none of the Company, the Trustee or any agent of the Company or the Trustee shall be affected by
notice to the contrary. 
  

 - 36 - 

 Title to any Bearer Security and any coupons appertaining thereto shall pass by delivery. The Company,
the Trustee and any agent of the Company or the Trustee may treat the bearer of any Bearer Security and the bearer of any coupon as the absolute owner of such Security or coupon for the purpose of receiving payment thereof or on account thereof and
for all other purposes whatsoever, whether or not such Security or coupons be overdue, and none of the Company, the Trustee or 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. The Company, the Trustee, the Paying
Agent and the Securities Registrar shall be entitled to deal with any depositary (including any Depositary or Common Depositary), and any nominee thereof, that is the Holder of any such global Security for all purposes of this Indenture relating to
such global Security (including the payment of principal, premium, if any, and interest and Additional Amounts, if any, the giving of instructions or directions by or to the owner or holder of a beneficial ownership interest in such global Security)
as the sole Holder of such global Security and shall have no obligations to the beneficial owners thereof. None of the Company, the Trustee, any Paying Agent or the Security Registrar shall have any responsibility or liability for any acts or
omissions of any such depositary with respect to such global Security, for the records of any such depositary, including records in respect of beneficial ownership interests in respect of any such global Security, for any transactions between such
depositary and any participant in such depositary or between or among any such depositary, any such participant and/or any holder or owner of a beneficial interest in such global Security or for any transfers of beneficial interests in any such
global Security. 
 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 (including any Depositary or Common 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 Holder of such global
Security. 
 Section 3.10 Cancellation. All Securities and coupons surrendered for payment, redemption, repayment at the option
of the Holder, registration of transfer or exchange or for credit against any current or future sinking fund payment shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee. All Securities and coupons so delivered to
the Trustee shall be promptly cancelled by it. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and may
deliver to the Trustee (or to any other Person for delivery to the Trustee) for cancellation any Securities previously authenticated hereunder which the Company has 

  

 - 37 - 

 
not issued and sold, and all Securities so delivered shall be promptly cancelled 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 cancelled as provided in this Section, except as expressly permitted by this Indenture. All cancelled Securities and coupons held by the Trustee shall be disposed of by the Trustee in accordance with its customary
procedures and, if requested by the Company in writing, certification of their disposal shall be delivered to the Company, unless by Company Order the Company shall timely direct that cancelled Securities be returned to it. 
 Section 3.11 Computation of Interest. Except as otherwise specified as contemplated by Section 3.1 with respect to Securities of any
series, interest, if any, on the Securities of each series shall be computed on the basis of a 360-day year of twelve 30-day months. 
 Section 3.12 Currency and Manner of Payments in Respect of Securities. 
 (a) Unless otherwise specified with respect to
any series of Securities pursuant to Section 3.1, with respect to Registered Securities of any series not permitting the election provided for in paragraph (b) below or the Holders of which have not made the election provided for in
paragraph (b) below, and with respect to Bearer Securities of any series, except as provided in paragraph (d) below, payment of the principal of (and premium, if any) and interest, if any, on any Registered or Bearer Security of such
series will be made in the Currency in which such Registered Security or Bearer Security, as the case may be, is payable. The provisions of this Section 3.12 may be modified or superseded with respect to any Securities pursuant to
Section 3.1. 
 (b) It may be provided pursuant to Section 3.1 with respect to Registered Securities of any series that Holders
shall have the option, subject to paragraphs (d) and (e) below, to receive payments of principal of (or premium, if any) or interest, if any, on such Registered Securities in any of the Currencies which may be designated for such election
by delivering to the Trustee a written election with signature guarantees and in the applicable form established pursuant to Section 3.1, not later than the close of business on the Election Date immediately preceding the applicable payment
date or at least 15 days prior to the date of Maturity. If a Holder so elects to receive such payments in any such Currency, such election will remain in effect for such Holder or any transferee of such Holder until changed by such Holder or such
transferee by written notice to the Trustee (but any such change must be made not later than the close of business on the Election Date immediately preceding the next payment date to be effective for the payment to be made on such payment date and
no such change of election may be made with respect to payments to be made on any Registered Security of such series with respect to which an Event of Default has occurred or with respect to which the Company has deposited funds pursuant to Article
Four or Fourteen or with respect to which a notice of redemption has been given by the Company or a notice of option to elect repayment has been sent by such Holder or such transferee). Any Holder of any such Registered Security who shall not have
delivered any such election to the 

  

 - 38 - 

 
Trustee not later than the close of business on the applicable Election Date will be paid the amount due on the applicable payment date in the relevant
Currency as provided in Section 3.12(a). The Trustee shall notify the Exchange Rate Agent as soon as practicable after the Election Date of the aggregate principal amount of Registered Securities for which Holders have made such written
election. 
 (c) Unless otherwise specified pursuant to Section 3.1, if the election referred to in paragraph (b) above has been
provided for pursuant to Section 3.1, then not later than the fourth Business Day after the Election Date for each payment date for Registered Securities of any series, the Exchange Rate Agent will deliver to the Company a written notice
specifying, in the Currency in which Registered Securities of such series are payable, the respective aggregate amounts of principal of (and premium, if any) and interest, if any, on the Registered Securities to be paid on such payment date,
specifying the amounts in such Currency so payable in respect of the Registered Securities as to which the Holders of Registered Securities of such series shall have elected to be paid in another Currency as provided in paragraph (b) above. If
the election referred to in paragraph (b) above has been provided for pursuant to Section 3.1 and if at least one Holder has made such election, then, unless otherwise specified pursuant to Section 3.1, on the second Business Day
preceding such payment date the Company will deliver to the Trustee for such series of Registered Securities an Exchange Rate Officer’s Certificate in respect of the Dollar or Foreign Currency payments to be made on such payment date. Unless
otherwise specified pursuant to Section 3.1, the Dollar or Foreign Currency amount receivable by Holders of Registered Securities who have elected payment in a Currency as provided in paragraph (b) above shall be determined by the Company
on the basis of the applicable Market Exchange Rate in effect on the third Business Day (the “Valuation Date”) immediately preceding each payment date, and such determination shall be conclusive and binding for all purposes, absent
manifest error. 
 (d) If a Conversion Event occurs with respect to a Foreign Currency in which any of the Securities are denominated or
payable other than pursuant to an election provided for pursuant to paragraph (b) above, then with respect to each date for the payment of principal of (and premium, if any) and interest, if any, on the applicable Securities denominated or
payable in such Foreign Currency occurring after the last date on which such Foreign Currency was used (the “Conversion Date”), the Dollar shall be the Currency of payment for use on each such payment date. Unless otherwise specified
pursuant to Section 3.1, the Dollar amount to be paid by the Company to the Trustee and by the Trustee or any Paying Agent to the Holders of such Securities with respect to such payment date shall be, in the case of a Foreign Currency other
than a currency unit, the Dollar Equivalent of the Foreign Currency or, in the case of a currency unit, the Dollar Equivalent of the Currency Unit, in each case as determined by the Exchange Rate Agent in the manner provided in paragraph (f) or
(g) below. 
 (e) Unless otherwise specified pursuant to Section 3.1, if the Holder of a Registered Security denominated in any
Currency shall have elected to be paid in another Currency as provided in paragraph (b) above, and a Conversion Event occurs with respect to such elected Currency, such Holder shall receive payment in the Currency in which payment would have
been made in the absence of such election; and if a 

  

 - 39 - 

 
Conversion Event occurs with respect to the Currency in which payment would have been made in the absence of such election, such Holder shall receive payment
in Dollars as provided in paragraph (d) above. 
 (f) The “Dollar Equivalent of the Foreign Currency” shall be determined by
the Exchange Rate Agent and shall be obtained for each subsequent payment date by converting the specified Foreign Currency into Dollars at the Market Exchange Rate on the Conversion Date. 
 (g) The “Dollar Equivalent of the Currency Unit” shall be determined by the Exchange Rate Agent and subject to the provisions of paragraph
(h) below shall be the sum of each amount obtained by converting the Specified Amount of each Component Currency into Dollars at the Market Exchange Rate for such Component Currency on the Valuation Date with respect to each payment.

 (h) For purposes of this Section 3.12 the following terms shall have the following meanings: 
 A “Component Currency” shall mean any Currency which, on the Conversion Date, was a component currency of the relevant currency unit,
including the Euro. 
 A “Specified Amount” of a Component Currency shall mean the number of units of such Component Currency
or fractions thereof which were represented in the relevant currency unit, including the Euro, on the Conversion Date. If after the Conversion Date the official unit of any Component Currency is altered by way of combination or subdivision, the
Specified Amount of such Component Currency shall be divided or multiplied in the same proportion. If after the Conversion Date two or more Component Currencies are consolidated into a single currency, the respective Specified Amounts of such
Component Currencies shall be replaced by an amount in such single Currency equal to the sum of the respective Specified Amounts of such consolidated Component Currencies expressed in such single Currency, and such amount shall thereafter be a
Specified Amount and such single Currency shall thereafter be a Component Currency. If after the Conversion Date any Component Currency shall be divided into two or more currencies, the Specified Amount of such Component Currency shall be replaced
by amounts of such two or more currencies, having an aggregate Dollar Equivalent value at the Market Exchange Rate on the date of such replacement equal to the Dollar Equivalent value of the Specified Amount of such former Component Currency at the
Market Exchange Rate immediately before such division and such amounts shall thereafter be Specified Amounts and such currencies shall thereafter be Component Currencies. If, after the Conversion Date of the relevant currency unit, including the
Euro, a Conversion Event (other than any event referred to above in this definition of “Specified Amount”) occurs with respect to any Component Currency 

  

 - 40 - 

 
of such currency unit and is continuing on the applicable Valuation Date, the Specified Amount of such Component Currency shall, for purposes of calculating
the Dollar Equivalent of the Currency Unit, be converted into Dollars at the Market Exchange Rate in effect on the Conversion Date of such Component Currency. 
 “Election Date” shall mean the date for any series of Registered Securities as specified pursuant to clause (13) of Section 3.1 by which the written election referred to in paragraph
(b) above may be made. 
 All decisions and determinations of the Exchange Rate Agent regarding the Dollar Equivalent of the Foreign
Currency, the Dollar Equivalent of the Currency Unit, the Market Exchange Rate and changes in the Specified Amounts as specified above shall be in its sole discretion and shall, in the absence of manifest error, be conclusive for all purposes and
irrevocably binding upon the Company, the Trustee and all Holders of such Securities denominated or payable in the relevant Currency. The Exchange Rate Agent shall promptly give written notice to the Company and the Trustee of any such decision or
determination. In the event that the Company determines in good faith that a Conversion Event has occurred with respect to a Foreign Currency, the Company will immediately give written notice thereof to the Trustee and to the Exchange Rate Agent
(and the Trustee will promptly thereafter give notice in the manner provided for in Section 1.6 to the affected Holders) specifying the Conversion Date. In the event the Company so determines that a Conversion Event has occurred with respect to
the Euro or any other currency unit in which Securities are denominated or payable, the Company will immediately give written notice thereof to the Trustee and to the Exchange Rate Agent (and the Trustee will promptly thereafter give notice in the
manner provided for in Section 1.6 to the affected Holders) specifying the Conversion Date and the Specified Amount of each Component Currency on the Conversion Date. In the event the Company determines in good faith that any subsequent change
in any Component Currency as set forth in the definition of Specified Amount above has occurred, the Company will similarly give written notice to the Trustee and the Exchange Rate Agent. The Trustee shall be fully justified and protected in relying
and acting upon information received by it from the Company and the Exchange Rate Agent and shall not otherwise have any duty or obligation to determine the accuracy or validity of such information independent of the Company or the Exchange Rate
Agent.

any substantial part of their property, or the making by them of an assignment for the benefit of creditors, or the admission by them in writing of their inability to pay their debts generally as they become due; or 
 (8) there occurs any other Event of Default provided pursuant to Section 3.1 or 9.1 with respect to Securities of that series. 
 Section 5.2 Acceleration of Maturity; Rescission and Annulment. If an Event of Default described in clause (1), (2), (3), (4), (5) or
(8) of Section 5.01 with respect to Securities of any series at the time Outstanding occurs and is continuing, then in every such case the Trustee or the Holders of not less than 25% in principal amount of the Outstanding Securities of
that series may declare the principal amount (or, if the Securities of that series are Original Issue Discount Securities or Indexed Securities, such portion of the principal amount as may be specified in the terms of that series) of all of the
Outstanding Securities of that series and any accrued and unpaid cash interest through 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 Holders), and upon any such
declaration such principal amount shall become immediately due and payable. 
  

 - 45 - 

 At any time after such a declaration of acceleration with respect to Securities of any series (or of all
series, as the case may be) has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of a majority in principal amount of the Outstanding
Securities of that series (or of all series, as the case may be) by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if: 
 (1) the Company has paid or deposited with the Trustee a sum sufficient to pay in the Currency in which the Securities of such series are payable (except
as otherwise specified pursuant to Section 3.1 for the Securities of such series and except, if applicable, as provided in Sections 3.12(b), 3.12(d) and 3.12(e)), 
 (A) all overdue interest, if any, on all Outstanding Securities of that series (or of all series, as the case may be) and any related coupons, 
 (B) all unpaid principal of (and premium, if any) any Outstanding Securities of that series (or of all series, as the case may be) which has become due

or, if no such rate or rates are so prescribed, at the rate borne by the Securities during the period of such default, 
 (D) all sums paid or
advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel (including in each case pursuant to Section 6.6); and

be) which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 5.13; and 
 (3)
such rescission would not conflict with any judgment or decree of a court of competent jurisdiction. 
 If an Event of Default described in
clause (6) or (7) occurs and is continuing, then the principal amounts (or, if the Securities of that series are Original Issue Discount Securities or Indexed Securities, such portion of the principal amount as may be specified in the
terms of that series) of all the Securities and then Outstanding, together with any accrued interest through the occurrence of such Event of Default, shall become and be due and payable immediately, without any declaration or other act by the

 Section 5.3 Collection of Indebtedness and Suits for Enforcement by Trustee. The Company
covenants that (1) in case default shall be made in the payment of any installment of interest on any Security of any series and any related coupon, as and when the same shall become due and payable, and such default shall have continued for a
period of 90 days, or (2) in case default shall be made in the payment of the principal (or premium, if any, on) any Security of any series at its Maturity and such default shall have continued for a period of five Business Days then, upon
demand of the Trustee, the Company will pay to the Trustee (such demand and payment in the case of Bearer Securities to occur only outside of the United States), for the benefit of the Holders of Securities of such series and coupons, the whole
amount that then shall have become due and payable on such Securities and coupons of that series for principal and any premium or interest, or both, as the case may be, with interest upon the overdue principal and (to the extent that payment of such
interest is enforceable under applicable law) upon overdue installments of interest at the rate borne by or provided for in such Securities during the period of such default; and, in addition thereto, such further amount as shall be sufficient to
cover reasonable compensation to the Trustee, its agents, attorneys and counsel, and all other expenses and liabilities incurred, and all advances made, by the Trustee except as a result of its negligence or bad faith.

discretion proceed to protect and enforce its rights and the rights of the Holders of Securities of such series (or of all series, as the case may be) and any related coupons 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. 
 Section 5.4 Trustee May File Proofs of Claim. In case of the pendency of any receivership, insolvency, liquidation, bankruptcy,

irrespective of whether the principal of the Securities of any series shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the payment
of any overdue principal, premium, if any, or interest, shall be entitled and empowered, by intervention in such proceeding or otherwise, 
 (1) to file and prove a claim for the whole amount of principal (and premium, if any) (or if the case of Original Issue Discount Securities or Indexed Securities, such portion of the principal amount as may be specified in the terms of such
series) and interest, if any, 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,

 (2) to collect and receive any moneys or other property payable or deliverable on any such claims and to
distribute the same (which distribution, in the case of Bearer Securities or coupons appertaining thereto, shall occur only outside the United States); and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar
official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any
amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 6.6. 
 Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Securities or coupons or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 
 Section 5.5 Trustee May Enforce Claims Without Possession of Securities. All rights of action and claims under this Indenture or the
Securities or coupons may be prosecuted and enforced by the Trustee without the possession of any of the Securities or coupons or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be
brought in its own name and 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 and coupons in respect of which such judgment has been recovered. 
 Section 5.6
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 any premium and interest, upon presentation of the Securities or coupons, or both, as the case may be (such presentation, in the case of Bearer Securities or coupons, to occur only outside the United States) 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 under
Section 6.6; 
 Second: To the payment (such payment, in the case of Bearer Securities or coupons, to occur only outside the United
States) of the amounts then due and unpaid for principal of and any premium and interest on the Securities and coupons in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any
kind, according to the amounts due and payable on such Securities and coupons for principal and any premium and interest, respectively; and 
 Third: To the payment of the remainder, if any, to the Company, or as a court of competent jurisdiction may direct in writing.

described in clause (1), (2), (3), (4), (5) or (8) of Section 5.01, or of Holders of all Securities in the case of any Event of Default described in clause (6) or (7) of Section 5.01, or to obtain or to seek to obtain

case of redemption or repayment at the option of the Holder, on the Redemption Date or Repayment Date, as the case may be) and to institute suit for the
enforcement of any such payment, and such rights shall not be impaired without the consent of such Holder. 
 Section 5.9 Restoration
of Rights and Remedies. If the Trustee or any Holder 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, subject to any determination in such proceeding, the Company, the Trustee and the Holders shall 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.

Rights and Remedies Cumulative. Except as otherwise provided with respect to replacement or payment of mutilated, destroyed, lost or stolen Securities or coupons in Section 3.6, no right or remedy herein conferred upon or reserved to the
Trustee or to the Holders of Securities and coupons is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be 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 5.11 Delay or Omission Not Waiver. No delay or omission of the Trustee or of any Holder of any Security or coupon 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 or coupons, as the case may be.

arising under clause (1), (2), (3), (4), (5) or (8) of Section 5.1 (provided, however, the Holders of not less than a majority in principal amount of all 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 relating to or arising under clause (6) or (7) of Section 5.1), and 
 (1) such direction shall not be in conflict with any rule of law or with this Indenture, 
 (2) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction, 
  

 - 50 - 

 (3) such direction is not unduly prejudicial to the rights of Holders of Securities of such series not
taking part in such direction, and 
 (4) such direction would not involve the Trustee in personal liability, as the Trustee, upon being
advised by counsel, shall reasonably determine. 
 Section 5.13 Waiver of Past Defaults. Subject to Section 5.2, the Holders
of not less than a majority in principal amount of Outstanding Securities of any series may on behalf of the Holders of all the Securities of such series waive any past default waive any past default described in clause (1), (2), (3), (4),

default), hereunder with respect to such series and its consequences, except a default: 
 (1) in respect of the payment of the principal of
or any premium and interest on any Security or any related coupon, or 
 (2) in respect of a covenant or provision hereof which under Article
Nine cannot be modified or amended without the consent of the Holder of each Outstanding Security of such series affected. 
 Upon any such
waiver, any such default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture, and the Company, the Trustee and Holders shall be restored to their former positions
and rights hereunder, respectively; but no such waiver shall extend to any subsequent or other default or Event of Default or impair any right consequent thereon. 
 Section 5.14 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, suffered 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 and expenses, 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 Security, or to any suit instituted by any Holder for the enforcement of the payment of the principal of (or premium if any, on) or interest on any Securities on or after the Stated Maturity or Maturities expressed in such
Security (or, in the case of redemption, on or after the Redemption Date). 
 Section 5.15 Waiver of Stay or Extension Laws. The
Company covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time
hereafter in force, which may affect the 

  

 - 51 - 

 
covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage
of any such law and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted. 
 ARTICLE VI 
 THE TRUSTEE

Securities of any series, the Trustee shall transmit in the manner and to the extent provided in TIA Section 313(c), notice of such default hereunder known to a Responsible Officer of the Trustee, unless such Default shall have 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, if any, on any Security of such series or in the payment of any sinking fund installment with respect to Securities
of such series, the Trustee shall be protected in withholding such notice if and so long as the board of directors, the executive committee or a trust committee of directors and/or Responsible Officers of the Trustee in good faith determine that the
withholding of such notice is in the interest of the Holders of Securities of such series and any related coupons; and provided further that in the case of any default or breach of the character specified in Section 5.1(4) with respect to
Securities and coupons of such series, no such notice to Holders shall be given until at least 30 days after the occurrence thereof.

 (b) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the
Trustee and conforming to the requirements of this Indenture; but in the case of any such certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine
the same to determine whether or not they conform to the requirements of this Indenture; 
 (2) if any Event of Default has occurred and is
continuing with respect to the Securities of any series, 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 person would exercise or use
under the circumstances in the conduct of such person’s own affairs; 
  

 - 52 - 

 (3) the Trustee may not be relieved from liabilities for its own negligent action, its own negligent
failure to act, or its own willful misconduct, except that:

(1) of this paragraph or the penultimate paragraph of this Section 6.2; 
 (b) the Trustee shall not be liable for any error of

costs and expenses (including reasonable fees and expenses of counsel) of defending itself or themselves against any claim or liability in connection with the exercise or performance of any of its or their powers or duties hereunder. 
 The obligations of the Company under this Section to compensate the Trustee, to pay or reimburse the Trustee for expenses, disbursements and advances and
to indemnify 

  

 - 55 - 

 
and hold harmless the Trustee shall constitute additional Indebtedness hereunder and shall survive the satisfaction and discharge of this Indenture, the
resignation or removal of the Trustee and the termination of this Indenture for any reason. As security for the performance of such obligations of the Company, the Trustee shall have a claim and lien prior to the Securities upon all property and
funds held or collected by the Trustee as such, except funds held in trust for the payment of principal of (or premium, if any) or interest, if any, on particular Securities or any coupons.

reports of condition at least annually, pursuant to law or to the requirements of Federal, State, territorial or District of Columbia supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such
corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section, it shall
resign immediately in the manner and with the effect hereinafter specified in this Article. If the Trustee shall have or acquire any conflicting interest within the meaning of the Trust Indenture Act, it shall either eliminate such conflicting
interest or resign to the extent, in the manner and with the effect, and subject to the conditions, provided in the Trust Indenture Act and this Indenture. For purposes of Section 3.10(b)(1) of the Trust Indenture Act and to the extent
permitted thereby, the Trustee, in its capacity as trustee in respect of the Securities of any series, shall not be deemed to have a conflicting interest arising from its capacity as trustee in respect of the Securities of any other series. Nothing
contained herein shall prevent the Trustee from filing the application provided for in the second to last sentence of Section 310(b) of the Trust Indenture Act. 
 Section 6.8 Resignation and Removal; Appointment of Successor. 
 (a) No resignation or removal of
the Trustee and no appointment of a successor Trustee pursuant to this Article shall become effective until the acceptance of appointment by the successor Trustee in accordance with the applicable requirements of Section 6.9 and any and all
amounts then due and owing to the Trustee hereunder have been paid in full. 
  

 - 56 - 

 (b) The Trustee may resign at any time with respect to the Securities of one or more series by giving
written notice thereof to the Company. If the instrument of acceptance by a successor Trustee required by Section 6.9 shall not have been delivered to the Trustee within 30 days after the giving of such notice of resignation, the resigning
Trustee may petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series. 
 (c) The Trustee may be removed at any time with respect to the Securities of any series by Act of the Holders of not less than a majority in principal amount of the Outstanding Securities of such series, delivered to the Trustee and to the
Company. 
 (d) If at any time: 
  

	 	(a)	the Trustee shall fail to comply with the provisions of TIA Section 310(b) after written request therefor by the Company or by any Holder who has been a bona fide Holder of a
Security for at least six months, or 

  

	 	(b)	the Trustee shall cease to be eligible under Section 6.7 and shall fail to resign after written request therefor by the Company or by any Holder who has been a bona fide Holder
of a Security for at least six months, or

shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, 

 then, in any such case, (i) the Company, by a Board Resolution, may remove the Trustee with respect to all Securities, or (ii) subject to TIA Section 315(e), any Holder who has been a bona fide Holder of a Security for at
least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee with respect to all Securities and the appointment of a successor Trustee or Trustees.

 (e) If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any
cause, with respect to the Securities of one or more series, the Company, by a Board Resolution, shall promptly appoint a successor Trustee or Trustees with respect to the Securities of that or those series (it being understood that any such
successor Trustee may be appointed with respect to the Securities of one or more or all of such series and that at any time there shall be only one Trustee with respect to the Securities of any particular series). If, within one year after such
resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee with respect to the Securities of any series shall be appointed by Act of the Holders of a majority in principal amount of the Outstanding Securities of
such series 

  

 - 57 - 

 
delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment, become the
successor Trustee with respect to the Securities of such series and to that extent supersede the successor Trustee appointed by the Company. If no successor Trustee with respect to the Securities of any series shall have been so appointed by the
Company or the Holders and accepted appointment in the manner hereinafter provided, any Holder who has been a bona fide Holder of a Security of such series for at least six months may, on behalf of himself and all others similarly situated, petition
any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series. 
 (f) The
Company shall give notice of each resignation and each removal of the Trustee with respect to the Securities of any series and each appointment of a successor Trustee with respect to the Securities of any series to the Holders of Securities of such
series in the manner provided for in Section 1.6. Each notice shall include the name of the successor Trustee with respect to the Securities of such series and the address of its Corporate Trust Office. 
 Section 6.9 Acceptance of Appointment by Successor. In case of the appointment hereunder of a successor Trustee with respect to all
Securities, every such successor Trustee so appointed shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall
become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on the request of the Company or the successor Trustee, such
retiring Trustee shall, upon payment of its charges, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor
Trustee all property and money held by such retiring Trustee hereunder, subject nevertheless to its claim and lien and its right to receive compensation, reimbursement and indemnity, all as provided for in Section 6.6. 
 (a) In case of the appointment hereunder of a successor Trustee with respect to the Securities of one or more (but not all) series, the Company, the
retiring Trustee and each successor Trustee with respect to the Securities of one or more series shall execute and deliver an indenture supplemental hereto wherein each successor Trustee shall accept such appointment and which (1) shall contain
such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each successor Trustee all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which
the appointment of such successor Trustee relates, (2) if the retiring Trustee is not retiring with respect to all Securities, shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that or those series as to which the retiring Trustee is not retiring shall continue to be vested in the retiring Trustee, and (3) shall 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, it being understood that nothing herein or in such supplemental indenture shall constitute such
Trustees co-trustees of the same trust and 

  

 - 58 - 

 
that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such
Trustee; and upon the execution and delivery of such supplemental indenture the resignation or removal of the retiring Trustee shall become effective to the extent provided therein and each such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates; but, on request of the Company
or any successor Trustee, such retiring Trustee shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder with respect to the Securities of that or those series to which the
appointment of such successor Trustee relates, subject nevertheless to its claim and lien and its right to receive compensation, reimbursement and indemnity, all as provided for in Section 6.6. Whenever there is a successor Trustee with respect
to one or more (but less than all) series of securities issued pursuant to this Indenture, the terms “Indenture” and “Securities” shall have the meanings specified in the provisos to the respective definitions of those terms in
Section 1.1 which contemplate such situation. 
 (b) Upon request of any such successor Trustee, the Company shall execute any and all
instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts referred to in paragraph (a) of this Section. 
 (c) No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible under
this Article. 
 Section 6.10 Merger, Conversion, Consolidation or Succession to Business. Any corporation into which the Trustee
may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all the corporate
trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such corporation shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of
any of the parties hereto. In case any Securities or coupons shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such
authentication and deliver the Securities or coupons so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities or coupons. In case any of the Securities shall not have been authenticated by such
predecessor Trustee, any successor Trustee may authenticate and deliver such Securities or coupons either in the name of any predecessor hereunder or in the name of the successor Trustee. In all such cases such certificates shall have the full force
and effect which this Indenture provides for the certificate of authentication of the Trustee; provided, however, that the right to adopt the certificate of authentication of any predecessor Trustee or to authenticate Securities in the name of any
predecessor Trustee shall apply only to its successor or successors by merger, conversion or consolidation. 
  

 - 59 - 

 Section 6.11 Appointment of Authenticating Agent. At any time when any of the Securities
remain Outstanding, the Trustee may appoint an Authenticating Agent or Agents with respect to one or more series of Securities which shall be authorized to act on behalf of the Trustee to authenticate Securities of such series and the Trustee shall
give written notice of such appointment to all Holders of Securities of the series with respect to which such Authenticating Agent will serve, in the manner provided for in Section 1.6. Securities so authenticated shall be entitled to the
benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Any such appointment shall be evidenced by an instrument in writing signed by a Responsible Officer of the Trustee, and a
copy of such instrument shall be promptly furnished to the Company. Wherever reference is made in this Indenture to the authentication and delivery of Securities by the Trustee or the Trustee’s certificate of authentication, such reference
shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent. Each Authenticating Agent shall be
acceptable to the Company and shall at all times be a corporation organized and doing business under the laws of the United States of America, any state thereof or the District of Columbia, authorized under such laws to act as Authenticating Agent,
having a combined capital and surplus of not less than $50,000,000 and subject to supervision or examination by federal or state authority. If such corporation publishes reports of condition at least annually, pursuant to law or to the requirements
of said supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so
published. If at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect specified in this Section. 
 Any corporation into which an Authenticating Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any
merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to the corporate agency or corporate trust business of an Authenticating Agent, shall continue to be an Authenticating Agent,
provided such corporation shall be otherwise eligible under this Section, without the execution or filing of any paper or any further act on the part of the Trustee or the Authenticating Agent. 
 An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee and to the Company. The Trustee may at any time terminate
the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Company. Upon receiving such a notice of resignation or upon such a termination, or in case at any time such Authenticating Agent shall
cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent which shall be acceptable to the Company and shall give written notice of such appointment to all Holders of Securities
of the series with respect to which such Authenticating Agent will serve, in the manner provided for in Section 1.6. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers
and duties of its predecessor hereunder, with 

  

 - 60 - 

 
like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of
this Section. 
 The Trustee agrees to pay to each Authenticating Agent from time to time reasonable compensation for its services under this
Section, and the Trustee shall be entitled to be reimbursed for such payments, pursuant to the provisions of Section 6.6. 
 If an
appointment with respect to one or more series is made pursuant to this Section, the Securities of such series may have endorsed thereon, in addition to the Trustee’s certificate of authentication, an alternate certificate of authentication in
the following form: 
 Dated:                     

 This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture.

authorized or permitted by this Indenture and, with respect to such Opinion of Counsel, that such supplemental indenture is a valid and binding obligation of the Company, enforceable against it in accordance with its terms (subject to customary
conditions), (2) a copy of the Board Resolution, certified by the Secretary of an Assistant Secretary of the Company, authorizing the execution of such supplemental indenture and (3) if such supplemental indenture is executed pursuant to
Section 9.2, evidence of the consent of the Holders required to consent thereto. The Trustee may, but shall not be obligated to, enter into any such supplemental indenture which affects the Trustee’s own rights, duties or immunities under
this Indenture or otherwise. 
 Section 9.4 Effect of Supplemental Indentures. Upon the execution of any supplemental indenture
under this Article, this Indenture shall be modified in accordance therewith, and such supplemental indenture shall form a part of this Indenture for all purposes; and every Holder of Securities theretofore or thereafter authenticated and delivered
hereunder and of any coupon appertaining thereto shall be bound thereby.

Every supplemental indenture executed pursuant to this Article shall conform to the requirements of the Trust Indenture Act as then in effect.

Trustee, bear a notation in form 

  

 - 65 - 

 
approved by the Trustee as to any matter provided for in such supplemental indenture. If the Company shall so determine, new Securities of any series so
modified as to conform, in the opinion of the Trustee and the Company, to any such supplemental indenture may be prepared and executed by the Company and upon receipt of a Company Order authenticated and delivered (which delivery, in the case of
Bearer Securities, shall occur only outside the United States) by the Trustee in exchange for Outstanding Securities of such series. 
 Section 9.7 Notice of Supplemental Indentures. Promptly after the execution by the Company and the Trustee of any supplemental indenture pursuant to the provisions of Section 9.2, the Company shall give notice thereof to
the Holders of each Outstanding Security affected, in the manner provided for in Section 1.6, setting forth in general terms the substance of such supplemental indenture; provided, that failure to give such notice, or any defect in the notice,
shall not impair or affect the validity of such supplemental indenture. 
 Section 9.8 Effect on Senior Indebtedness. No
supplemental indenture shall adversely affect the rights of any holder of Senior Indebtedness without the consent of such holder.

 COVENANTS 
 Section 10.1 Payment of Principal, Premium, if Any, and Interest. The Company covenants and agrees for the benefit of the Holders of each series of Securities and any related coupons that it will duly and
punctually pay the principal of and any premium and interest on the Securities of that series in accordance with the terms of the Securities, any coupons appertaining thereto and this Indenture. Unless specified as contemplated by Section 3.1
with respect to any series of Securities, any interest installments due on Bearer Securities on or before Maturity shall be payable only upon presentation and surrender of the several coupons for such interest installments as are evidenced thereby
as they severally mature. 
 Section 10.2 Maintenance of Office or Agency. If the Securities of a series are issuable only as
Registered Securities, the Company will maintain in each Place of Payment for any series of Securities an office or agency where the Securities may be presented or surrendered for payment, where the Securities may be surrendered for registration of
transfer or exchange, where Securities of that series that are convertible or exchangeable may be surrendered for conversion or exchange, as applicable, and where notices and demands to or upon the Company in respect of the Securities and this
Indenture may be served. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain 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 except that Bearer Securities of any series and related coupons may be
presented and surrendered for payment only outside the United States, at the offices specified in the Security, and the Company hereby appoints the Trustee as its agent to receive all such presentations, surrenders, notices and demands. Unless
otherwise specified with respect to any 

  

 - 66 - 

 
Securities as contemplated by Section 3.1 with respect to a series of Securities, the Company hereby designates as a Place of Payment for each series of
Securities the office or agency of the Trustee in the City of Wilmington, Delaware, and initially appoints the Trustee at its Corporate Trust Office as Paying Agent in such city and as its agent to receive all such presentations, surrenders, notices
and demands. 
 Unless otherwise specified with respect to any Securities pursuant to Section 3.1, no payment of principal, premium or
interest on Bearer Securities shall be made at any office or agency of the Company in the United States or by check mailed to any address in the United States or by transfer to an account maintained with a bank located in the United States;
provided, however, that, if the Securities of a series are payable in Dollars, payment of principal of (and premium, if any) and interest, if any, on any Bearer Security shall be made at the office of the Company’s Paying Agent in The City of
New York, if (but only if) payment in Dollars of the full amount of such principal, premium or interest, as the case may be, at all offices or agencies outside the United States maintained for such purpose by the Company in accordance with this
Indenture is illegal or effectively precluded by exchange controls or other similar restrictions. 
 The Company may also from time to time
designate one or more other offices or agencies where the Securities of one or more series may be presented or surrendered for any or all such purposes and may from time to time rescind any such designation; 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 Securities of any series for such purposes. The Company will 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. Unless otherwise specified with respect to any Securities as contemplated by Section 3.1 with respect to a
series of Securities, the Company hereby designates as a Place of Payment for each series of Securities the office or agency of the Trustee in the City of Wilmington, Delaware, and initially appoints the Trustee at its Corporate Trust Office as
Paying Agent in such city and as its agent to receive all such respective presentations, surrenders, notices and demands. 
 Unless otherwise
specified with respect to any Securities pursuant to Section 3.1, if and so long as the Securities of any series (i) are denominated in a Currency other than Dollars or (ii) may be payable in a Currency other than Dollars, or so long
as it is required under any other provision of the Indenture, then the Company will maintain with respect to each such series of Securities, or as so required, at least one Exchange Rate Agent. 
 Section 10.3 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 series of Securities and any related coupons, it will, on or before each due date of the principal of or any premium and interest on any of the Securities of that series, segregate and hold in trust for the benefit of the Persons entitled
thereto a sum sufficient to pay all amounts payable to the Trustee under Section 6.6 and a sum in the Currency in which the Securities of such series are payable (except as otherwise specified pursuant to Section 

  

 - 67 - 

 
3.1 for the Securities of such series and except, if applicable, as provided in Sections 3.12(b), 3.12(d) and 3.12(e)) sufficient to pay the principal and
any premium and interest on Securities of such series so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided and will promptly notify the Trustee of its action or failure so to act. Whenever the
Company shall have one or more Paying Agents for any series of Securities and any related coupons, it will, prior to each due date of the principal of or any premium and interest on any Securities, deposit with a Paying Agent a sum (in the Currency
described in the preceding paragraph) sufficient to pay such amount so becoming due, such sum to be held as provided by the Trust Indenture Act, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of its action
or failure so to act. 
 The Company will cause each Paying Agent for any series of Securities other than the Trustee to execute and deliver
to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent will (i) comply with the provisions of the Trust Indenture Act applicable to it as a Paying
Agent and (ii) during the continuance of any default by the Company (or any other obligor upon the Securities) in the making of any payment in respect of the Securities, and upon written request of the Trustee, forthwith pay to the Trustee all
sums held in trust by such Paying Agent for payment in respect of the Securities and to account for any monies already paid. 
 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 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. 
 Except as provided in the Securities of any series, and subject to any applicable abandoned Property
laws, 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 or any premium or interest on any Security of any series, or any coupon appertaining thereto, and remaining
unclaimed for two years after such principal, premium and interest has become due and payable shall be paid to the Company on Company Request, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Security or
coupon shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, 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 in each Place of Payment,
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 will be repaid to the Company.

 Section 10.4 Statement by Officers as to Default. 
 (a) The Company will deliver to the Trustee, within 120 days after the end of each fiscal year of the Company ending after the date hereof, an
Officers’ Certificate, one of the signers of which shall be the principal executive officer, principal financial officer or principal accounting officer of the Company stating whether or not to the best knowledge of the signers thereof the
Company is in default in the performance and observance of any of the terms, provisions and conditions of this Indenture (without regard to any period of grace or requirement of notice provided hereunder) and, if the Company shall be in default,
specifying all such defaults and the nature and status thereof of which they may have knowledge. 
 (b) The Company shall, so long as any of
Securities of any series are Outstanding, deliver to the Trustee, forthwith, but in no event later than five Business Days, upon any Officer becoming aware of any event which after notice or lapse of time would become a Default or Event of Default
under Section 5.1, a notice specifying such Default or Event of Default and what action the Company is taking or proposes to take with respect thereto. 
 Section 10.5 Existence. The Company will do or cause to be done all things necessary to preserve and keep in full force and effect its existence, rights (charter and statutory) and franchises; provided,
however, that the Company shall not be required to preserve any such right or franchise if its 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 10.6 Further Instruments and Acts. Upon request
of the Trustee or as otherwise necessary, the Company will execute and deliver such further instruments and do such further acts or as otherwise necessary may be reasonably necessary or proper to carry out more effectively the purposes of this
Indenture. 
 Section 10.7 Calculation of Original Issue Discount. Upon request of the Trustee, the Company shall file with the
Trustee promptly at the end of each calendar year a written notice specifying the amount of original issue discount (including daily rates and accrual periods), if any, accrued on Outstanding Securities as of the end of such year. 
 Section 10.8 Additional Amounts. If any Securities of a series provide for the payment of additional amounts to any Holder who is not a
United States person in respect of any tax, assessment or governmental charge (“Additional Amounts”), the Company will pay to the Holder of any Security of such series or any coupon appertaining thereto such Additional Amounts as may be
specified as contemplated by Section 3.1. Whenever in this Indenture there is mentioned, in any context, the payment of the principal (or premium, if any) or interest, if any, on, or in respect of, any Security of a series or payment of any
related coupon or the net proceeds received on the sale or exchange of any Security of a series, such mention shall be deemed to include mention of the payment of Additional Amounts provided for by the terms of such series established pursuant to

  

 - 69 - 

 
Section 3.1 to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof pursuant to such terms and express
mention of the payment of Additional Amounts (if applicable) in any provisions hereof shall not be construed as excluding Additional Amounts in those provisions hereof where such express mention is not made. 
 Except as otherwise specified as contemplated by Section 3.1, if the Securities of a series provide for the payment of Additional Amounts, at least
10 days prior to the first Interest Payment Date with respect to that series of Securities (or if the Securities of that series will not bear interest prior to Maturity, the first day on which a payment of principal (and premium, if any) is made),
and at least 10 days prior to each date of payment of principal (or premium, if any) or interest if there has been any change with respect to the matters set forth in the below-mentioned Officer’s Certificate, the Company will furnish the
Trustee and the Company’s principal Paying Agent or Paying Agents, if other than the Trustee, with an Officer’s Certificate instructing the Trustee and such Paying Agent or Paying Agents whether such payment of principal, premium or
interest on the Securities of that series shall be made to Holders of Securities of that series or any related coupons who are not United States persons without withholding for or on account of any tax, assessment or other governmental charge
described in the Securities of the series. If any such withholding shall be required, then such Officer’s Certificate shall specify by country and the amount, if any, required to be withheld on such payments to such Holders of Securities of
that series or related coupons and the Company will pay to the Trustee or such Paying Agent the Additional Amounts required by the terms of such Securities. In the event that the Trustee or any Paying Agent, as the case may be, shall not so receive
the above-mentioned certificate, then the Trustee or such Paying Agent shall be entitled to (i) assume that no such withholding or deduction is required with respect to any payment of principal of (or premium, if any) or interest, if any, on
any Securities of a series or related coupons until it shall have received a certificate advising otherwise and (ii) to make all payments of principal of (and premium, if any) and interest, if any, on the Securities of a series or related
coupons without withholding or deductions until otherwise advised. The Company covenants to indemnify the Trustee, any Paying Agent, and their respective officers, directors, employees, and agents for, and to hold them harmless against, any loss,
liability or expense reasonably incurred without negligence or bad faith on their part arising out of or in connection with actions taken or omitted by any of them in reliance on any Officer’s Certificate furnished pursuant to this Section.
This sentence shall survive the termination of this Indenture and the earlier resignation or removal of the Trustee. 
 Section 10.9
Merger, Consolidation and Sale of Assets. 
 (a) The Company shall not consolidate with or merge with or into any other Person or
convey, transfer or lease all or substantially all of its properties and assets to any Person, unless: 
 (i) the resulting, surviving or
transferee Person, if not the Company, is a corporation organized and existing under the laws of the United States of America, any State thereof or the District of Columbia, and such Person, if not the Company, expressly assumes by supplemental
indenture all of the Company’s obligations under any Securities and this Indenture; 
  

 - 70 - 

 (ii) immediately after giving effect to such transaction, no Default has occurred and is continuing under
this Indenture; and 
 (iii) the Company has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating
that such consolidation, merger, conveyance, transfer or lease and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture complies with this Section 10.9 and that all conditions precedent
herein provided for relating to such transaction have been complied with. 
 (b) Upon any consolidation of the Company with, or merger of the
Company into, any other Person or any conveyance, transfer or lease of all or substantially all of the properties and assets of the Company in accordance with Section 10.9(a), the successor Person formed by such consolidation or into which the
Company is merged or to which such conveyance, transfer or lease is made shall succeed to, and be substituted for, and may exercise every right and power of, the Company under this Indenture with the same effect as if such successor Person had been
named as the Company herein, and thereafter, except in the case of a lease, the predecessor Person shall be relieved of all obligations and covenants under this Indenture and any Securities. 
 Section 10.10 Waiver of Certain Covenants. The Company may, with respect to any series of Securities, omit in any particular instance to
comply with any term, provision or condition which affects such series set forth in Sections 10.5 or as specified pursuant to Section 3.1(15) for Securities of such series, in any covenants of the Company added to Article Ten pursuant to
Section 3.1(14) or Section 3.1(15) in connection with Securities of such series, if the Holders of at least a majority in principal amount of all Outstanding Securities affected by such term, provision or condition, by Act of such Holders,
waive such compliance in such instance with such term, provision or condition (provided that evidence of such waiver is presented to the Trustee), but no such waiver shall extend to or affect such term, provision 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 to Holders of Securities of such series in respect of any such term, provision or condition shall remain in full force and
effect. 
 ARTICLE XI 
 REDEMPTION OF SECURITIES 
 Section 11.1 Applicability of Article. Securities of any series which are redeemable
before their Stated Maturity shall be redeemable in accordance with the terms of such Securities and (except as otherwise specified as contemplated by Section 3.1 for Securities of any series) in accordance with this Article. 
 Section 11.2 Election to Redeem; Notice to Trustee. The election of the Company to redeem any Securities shall be evidenced by or pursuant to
a Board 

  

 - 71 - 

 
Resolution. In case of any redemption at the election of the Company, the Company shall, at least 60 days prior to the Redemption Date fixed by the Company
(unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee of such Redemption Date and of the principal amount of Securities of such series to be redeemed and shall deliver to the Trustee such documentation and records as
shall enable the Trustee to select the Securities to be redeemed pursuant to Section 11.3. 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 Officer’s Certificate evidencing compliance with such restriction. 
 Section 11.3 Selection by Trustee of Securities to Be Redeemed. If less than all the Securities of any series are to be redeemed, the particular Securities to be redeemed shall be selected not more than 60 days prior to the
Redemption Date by the Trustee, from the Outstanding Securities of such series not previously called for redemption, by such method as the Trustee shall deem reasonable and which may provide for the selection for redemption of portions of the
principal of Securities of such series; provided, however, that no such partial redemption shall reduce the portion of the principal amount of a Security not redeemed to less than the minimum authorized denomination for Securities of such series
established pursuant to Section 3.1 and Section 3.2. 
 The Trustee shall promptly notify the Company 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 11.4 Notice of Redemption. Except as otherwise
specified as contemplated by Section 3.1 for Securities of any series, notice of redemption shall be given in the manner provided for in Section 1.6 not less than 30 nor more than 60 days prior to the Redemption Date, to each Holder of
Securities to be redeemed. 
 Except as otherwise specified as contemplated by Section 3.1 for Securities of any series, all notices of
redemption shall state: 
 (1) the Redemption Date, 
 (2) the Redemption Price (if known) or the formula pursuant to which the Redemption Price is to be determined if the Redemption Price cannot be determined at the time the notice is given, 
 (3) if less than all the Outstanding Securities of any series are to be redeemed, the identification (and, in the case of partial redemption, the
principal amounts) of the particular Securities to be redeemed, 
  

 - 72 - 

 (4) in case any Security is to be redeemed in part only, the notice which relates to such Security shall
state that on and after the Redemption Date, upon surrender of such Security, the Holder will receive, without charge, a new Security or Securities of authorized denominations for the principal amount thereof remaining unredeemed, 
 (5) that on the Redemption Date, the Redemption Price and accrued interest, if any, to the Redemption Date payable as provided in Section 11.6 will
become due and payable upon each such Security, or the portion thereof, to be redeemed and, if applicable, that interest thereon will cease to accrue on and after said date, 
 (6) the Place or Places of Payment (which in the case of Bearer Securities shall be outside the United States) where such Securities, together in the
case of Bearer Securities with all coupons appertaining thereto, if any, maturing after the Redemption Date, are to be surrendered for payment of the Redemption Price and accrued interest, if any, 
 (7) that the redemption is for a sinking fund, if such is the case, 
 (8) that, unless otherwise specified in such notice, Bearer Securities of any series, if any, surrendered for redemption must be accompanied by all coupons maturing subsequent to the Redemption Date or the amount of
any such missing coupon or coupons will be deducted from the Redemption Price unless security or indemnity satisfactory to the Company, the Trustee and any Paying Agent is furnished, 
 (9) if Bearer Securities of any series are to be redeemed and any Registered Securities of such series are not to be redeemed, and if such Bearer
Securities may be exchanged for Registered Securities not subject to redemption on such Redemption Date pursuant to Section 3.5 or otherwise, the last date, as determined by the Company, on which such exchanges may be made, 
 (10) the CUSIP, ISIN or other similar numbers, if any, assigned to such Securities; provided, however, that such notice may state that no representation
is made as to the correctness of CUSIP, ISIN or other similar numbers, in which case none of the Company, the Trustee or any agent of the Company or the Trustee shall have any liability in respect of the use of any CUSIP, ISIN or other similar
number or numbers on such notices, and the redemption of such Securities shall not be affected by any defect in or omission of such numbers, and 
 (11) such other matters as the Company shall deem desirable or appropriate. 
 Notice of redemption of Securities to be redeemed at
the election of the Company 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 11.5 Deposit of Redemption Price. On or prior to any Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the 

  

 - 73 - 

 
Company is acting as its own Paying Agent, which it may not do in the case of a sinking fund payment under Article Twelve, segregate and hold in trust as
provided in Section 10.3) an amount of money in same day funds in the Currency in which the Securities of such series are payable (except as otherwise specified pursuant to Section 3.1 for the Securities of such series and except, if
applicable, as provided in Sections 3.12(b), 3.12(d) and 3.12(e)) sufficient to pay on the Redemption Date the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date) accrued interest, if any, on, all the
Securities or portions thereof which are to be redeemed on that date. 
 Section 11.6 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 in the Currency in which the Securities of such series are payable
(except as otherwise specified pursuant to Section 3.1 for the Securities of such series and except, if applicable, as provided in Sections 3.12(b), 3.12(d) and 3.12(e)) (together with accrued interest, if any, to the Redemption Date), and from
and after such date (unless the Company shall default in the payment of the Redemption Price and accrued interest, if any) such Securities shall, if the same were interest-bearing, cease to bear interest and the coupons for such interest
appertaining to any Bearer Securities so to be redeemed, except to the extent provided below, shall be void. Upon surrender of any such Security for redemption in accordance with said notice, together with all coupons, if any, appertaining thereto
maturing after the Redemption Date, such Security shall be paid by the Company at the Redemption Price, together with accrued interest, if any, to the Redemption Date; provided, however, that installments of interest on Bearer Securities whose
Stated Maturity is on or prior to the Redemption Date shall be payable only at an office or agency located outside the United States (except as otherwise provided in Section 10.2) and, unless otherwise specified as contemplated by
Section 3.1, only upon presentation and surrender of coupons for such interest; and provided further that installments of interest on Registered Securities whose Stated Maturity is on or prior to the Redemption Date shall be payable to the
Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the relevant Record Dates according to their terms and the provisions of Section 3.7. 
 If any Bearer Security surrendered for redemption shall not be accompanied by all appurtenant coupons maturing after the Redemption Date, such Security
may be paid after deducting from the Redemption Price an amount equal to the face amount of all such missing coupons, or the surrender of such missing coupon or coupons may be waived by the Company and the Trustee if there be furnished to them such
security or indemnity as they may require to save each of them and any Paying Agent harmless. If thereafter the Holder of such Security shall surrender to the Trustee or any Paying Agent any such missing coupon in respect of which a deduction shall
have been made from the Redemption Price, such Holder shall be entitled to receive the amount so deducted; provided, however, that interest represented by coupons shall be payable only at an office or agency located outside the United States (except
as otherwise provided in Section 10.2) and, unless otherwise specified as contemplated by Section 3.1, only upon presentation and surrender of those coupons. 
  

 - 74 - 

 If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the
principal (and premium, if any) shall, until paid, bear interest from the Redemption Date at the rate of interest or Yield to Maturity (in the case of Original Issue Discount Securities) set forth in such Security. 
 Section 11.7 Securities Redeemed in Part. Any Security which is to be redeemed only in part (pursuant to the provisions of this Article or of
Article Twelve) 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 such Holder’s attorney duly authorized in writing), and the Company shall execute, and upon receipt of a Company Order the Trustee shall authenticate and deliver to the Holder of such Security without service charge, a new
Security or Securities of the same series and of like tenor, 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. If any definitive Security is redeemed only in part, the Company may block the transfer or exchange of such Security during the period beginning 15 days prior to the date of mailing of the notice relating to such redemption and ending
on the day of such mailing, in order to freeze the list of holders to prepare the mailing. The Company may also refuse to register transfers or exchanges of any such Security, except that it may continue to permit transfers and exchanges of the
unredeemed portion of any such Security. 
 ARTICLE XII 
 SINKING FUNDS 
 Section 12.1 Applicability of Article. Retirements of Securities of any
series pursuant to any sinking fund shall be made in accordance with the terms of such Securities and (except as otherwise specified as contemplated by Section 3.1 for Securities of any series) in accordance with this Article. 
 The minimum amount of any sinking fund payment provided for by the terms of Securities of any series is herein referred to as a “mandatory sinking
fund payment”, and any payment in excess of such minimum amount provided for by the terms of Securities of any series is herein referred to as an “optional sinking fund payment”. If provided for by the terms of Securities of any
series, the cash amount of any mandatory sinking fund payment may be subject to reduction as provided in Section 12.2. Each sinking fund payment shall be applied to the redemption of Securities of any series as provided for by the terms of
Securities of such series. 
 Section 12.2 Satisfaction of Sinking Fund Payments with Securities. Subject to Section 12.3,
in lieu of making all or any part of any mandatory sinking fund payment with respect to any Securities of a series in cash, the Company may at its option (1) deliver to the Trustee Outstanding Securities of a series (other than any previously
called for redemption) theretofore purchased or otherwise acquired by the Company, together, in the case of any Bearer Securities of such series, with all unmatured coupons appertaining thereto, and/or (2) receive credit for the principal
amount of Securities of 

  

 - 75 - 

 
such series which have been previously delivered to the Trustee by the Company or for Securities of such series which have been redeemed either at the
election of the Company pursuant to the terms of such Securities or through the application of permitted optional sinking fund payments pursuant to the terms of such Securities, in each case in satisfaction of all or any part of any mandatory
sinking fund payment with respect to the Securities of the same series required to be made pursuant to the terms of such Securities as provided for by the terms of such series; provided, however, that such Securities have not been previously so
credited. Such Securities shall be received and credited for such purpose by the Trustee at the Redemption Price specified in such Securities for redemption through operation of the sinking fund and the amount of such mandatory sinking fund payment
shall be reduced accordingly. 
 Section 12.3 Redemption of Securities for Sinking Fund. Not less than 60 days prior to each
sinking fund payment date for any series of Securities, the Company will deliver to the Trustee an Officer’s Certificate specifying the amount of the next ensuing sinking fund payment for that series pursuant to the terms of that series, the
portion thereof, if any, which is to be satisfied by payment of cash in the Currency in which the Securities of such series are payable (except as otherwise specified pursuant to Section 3.1 for the Securities of such series and except, if
applicable, as provided in Sections 3.12(b), 3.12(d) and 3.12(e)) and the portion thereof, if any, which is to be satisfied by delivering or crediting Securities of that series pursuant to Section 12.2 (which Securities will, if not previously
delivered, accompany such certificate) and whether the Company intends to exercise its right to make a permitted optional sinking fund payment with respect to such series. Such certificate shall be irrevocable and upon its delivery the Company shall
be obligated to make the cash payment or payments therein referred to, if any, on or before the next succeeding sinking fund payment date. In the case of the failure of the Company to deliver such certificate, the sinking fund payment due on the
next succeeding sinking fund payment date for that series shall be paid entirely in cash and shall be sufficient to redeem the principal amount of such Securities subject to a mandatory sinking fund payment without the option to deliver or credit
Securities as provided in Section 12.2 and without the right to make any optional sinking fund payment, if any, with respect to such series. 
 Not more than 60 days before each such sinking fund payment date the Trustee shall select the Securities to be redeemed upon such sinking fund payment date in the manner specified in Section 11.3 and cause notice of the redemption
thereof to be given in the name of and at the expense of the Company in the manner provided in Section 11.4. Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated in Sections
11.6 and 11.7. 
 Prior to any sinking fund payment date, the Company shall pay to the Trustee or a Paying Agent (or, if the Company is
acting as its own Paying Agent, segregate and hold in trust as provided in Section 10.3) in cash a sum equal to the principal (and premium, if any) and any interest that will accrue to the date fixed for redemption of Securities or portions
thereof to be redeemed on such sinking fund payment date pursuant to this Section 12.3. 
  

 - 76 - 

 Notwithstanding the foregoing, with respect to a sinking fund for any series of Securities, if at any
time the amount of cash to be paid into such sinking fund on the next succeeding sinking fund payment date, together with any unused balance of any preceding sinking fund payment or payments for such series, does not exceed in the aggregate
$100,000, the Trustee, unless requested by the Company, shall not give the next succeeding notice of the redemption of Securities of such series through the operation of the sinking fund. Any such unused balance of moneys deposited in such sinking
fund shall be added to the sinking fund payment for such series to be made in cash on the next succeeding sinking fund payment date or, at the request of the Company, shall be applied at any time or from time to time to the purchase of Securities of
such series, by public or private purchase, in the open market or otherwise, at a purchase price for such Securities (excluding accrued interest and brokerage commissions, for which the Trustee or any Paying Agent will be reimbursed by the Company)
not in excess of the principal amount thereof. 
 ARTICLE XIII 
 REPAYMENT AT OPTION OF HOLDERS 
 Section 13.1 Applicability of
Article. Repayment of Securities of any series before their Stated Maturity at the option of Holders thereof shall be made in accordance with the terms of such Securities and (except as otherwise specified as contemplated by Section 3.1 for
Securities of any series) in accordance with this Article. 
 Section 13.2 Repayment of Securities. Securities of any series
subject to repayment in whole or in part at the option of the Holders thereof will, unless otherwise provided in the terms of such Securities, be repaid at the Repayment Price thereof, together with interest, if any, thereon accrued to the Repayment
Date specified in or pursuant to the terms of such Securities. The Company covenants that on or before the Repayment Date it will 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 10.3) an amount of money in the Currency in which the Securities of such series are payable (except as otherwise specified pursuant to Section 3.1 for the Securities of such series and except, if
applicable, as provided in Sections 3.12(b), 3.12(d) and 3.12(e)) sufficient to pay the Repayment Price of, and (except if the Repayment Date shall be an Interest Payment Date) accrued interest, if any, on, all the Securities or portions thereof, as
the case may be, to be repaid on such date. 
 Section 13.3 Exercise of Option. Securities of any series subject to repayment at
the option of the Holders thereof will contain an “Option to Elect Repayment” form on the reverse of such Securities. To be repaid at the option of the Holder, any Security so providing for such repayment, with the “Option to Elect
Repayment” form on the reverse of such Security duly completed by the Holder (or by the Holder’s attorney duly authorized in writing), must be received by the Company at the Place of Payment therefor specified in the terms of such Security
(or at such other place or places of which the Company shall from time to time notify the Holders of such Securities) not earlier than 45 days nor later than 30 days prior to the Repayment Date. If less than the entire Repayment Price of such
Security is to be repaid in accordance with the terms of such 

  

 - 77 - 

 
Security, the portion of the Repayment Price of such Security to be repaid, in increments of the minimum denomination for Securities of such series, and the
denomination or denominations of the Security or Securities to be issued to the Holder for the portion of such Security surrendered that is not to be repaid, must be specified. Any Security providing for repayment at the option of the Holder thereof
may not be repaid in part if, following such repayment, the unpaid principal amount of such Security would be less than the minimum authorized denomination of Securities of the series of which such Security to be repaid is a part. Except as
otherwise may be provided by the terms of any Security providing for repayment at the option of the Holder thereof, exercise of the repayment option by the Holder shall be irrevocable unless waived by the Company. 
 Section 13.4 When Securities Presented for Repayment Become Due and Payable. If Securities of any series providing for repayment at the
option of the Holders thereof shall have been surrendered as provided in this Article and as provided by or pursuant to the terms of such Securities, such Securities or the portions thereof, as the case may be, to be repaid shall become due and
payable and shall be paid by the Company on the Repayment Date therein specified, and on and after such Repayment Date (unless the Company shall default in the payment of such Securities on such Repayment Date) such Securities shall, if the same
were interest-bearing, cease to bear interest and the coupons for such interest appertaining to any Bearer Securities so to be repaid, except to the extent provided below, shall be void. Upon surrender of any such Security for repayment in
accordance with such provisions, together with all coupons, if any, appertaining thereto maturing after the Repayment Date, the Repayment Price of such Security so to be repaid shall be paid by the Company, together with accrued interest, if any, to
the Repayment Date; provided, however, that coupons whose Stated Maturity is on or prior to the Repayment Date shall be payable only at an office or agency located outside the United States (except as otherwise provided in Section 10.2) and,
unless otherwise specified pursuant to Section 3.1, only upon presentation and surrender of such coupons; and provided further that, in the case of Registered Securities, installments of interest, if any, whose Stated Maturity is on or prior to
the Repayment Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the relevant Record Dates according to their terms and the provisions of Section 3.7.

 If any Bearer Security surrendered for repayment shall not be accompanied by all appurtenant coupons maturing after the Repayment Date,
such Security may be paid after deducting from the amount payable therefor as provided in Section 13.2 an amount equal to the face amount of all such missing coupons, or the surrender of such missing coupon or coupons may be waived by the
Company and the Trustee if there be furnished to them such security or indemnity as they may require to save each of them and any Paying Agent harmless. If thereafter the Holder of such Security shall surrender to the Trustee or any Paying Agent any
such missing coupon in respect of which a deduction shall have been made as provided in the preceding sentence, such Holder shall be entitled to receive the amount so deducted; provided, however, that interest represented by coupons shall be payable
only at an office or agency located outside the United States (except as otherwise provided in Section 10.2) and, unless otherwise specified as contemplated by Section 3.1, only upon presentation and surrender of those coupons. If the
principal amount of any 

  

 - 78 - 

 
Security surrendered for repayment shall not be so repaid upon surrender thereof, such principal amount (together with interest, if any, thereon accrued to
such Repayment Date) shall, until paid, bear interest from the Repayment Date at the rate of interest or Yield to Maturity (in the case of Original Issue Discount Securities) set forth in such Security. 
 Section 13.5 Securities Repaid in Part. Upon surrender of any Registered Security which is to be repaid in part only, the Company shall
execute and upon receipt of a Company Order the Trustee shall authenticate and deliver to the Holder of such Security, without service charge and at the expense of the Company, a new Registered Security or Securities of the same series, and of like
tenor, of any authorized denomination specified by the Holder, in an aggregate principal amount equal to and in exchange for the portion of the principal of such Security so surrendered which is not to be repaid. 
 ARTICLE XIV 
 DEFEASANCE AND COVENANT
DEFEASANCE 
 Section 14.1 Company’s Option to Effect Defeasance or Covenant Defeasance. Except as otherwise specified
as contemplated by Section 3.1 for Securities of any series, the provisions of this Article Fourteen shall apply to each series of Securities, and the Company may, at its option, effect defeasance of the Securities of or within a series under
Section 14.2, or covenant defeasance of or within a series under Section 14.3 in accordance with the terms of such Securities and in accordance with this Article. 
 Section 14.2 Defeasance and Discharge. Upon the Company’s exercise of the above option applicable to this Section with respect to any
Securities of or within a series, the Company shall be deemed to have been discharged from its obligations with respect to such Outstanding Securities and any related coupons on the date the conditions set forth in Section 14.4 are satisfied
(hereinafter, “defeasance”). For this purpose, such defeasance means that the Company shall be deemed to have paid and discharged the entire Indebtedness represented by such Outstanding Securities and any related coupons, which shall
thereafter be deemed to be “Outstanding” only for the purposes of Section 14.5 and the other Sections of this Indenture referred to in (A) and (B) below, and to have satisfied all its other obligations under such Securities
and any related coupons and this Indenture insofar as such Securities and any related coupons are concerned (and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following which
shall survive until otherwise terminated or discharged hereunder: (A) the rights of Holders of such Outstanding Securities and any related coupons to receive, solely from the trust fund described in Section 14.4 and as more fully set forth
in such Section, payments in respect of the principal of (and premium, if any) and interest, if any, on such Securities and any related coupons when such payments are due, (B) the Company’s obligations with respect to such Securities under
Sections 3.4, 3.5, 3.6, 10.2 and 10.3 and with respect to the payment of Additional Amounts, if any, on such Securities as contemplated by Section 10.8 and such obligations as shall be ancillary thereto, (C) the rights, powers, trusts,
duties and immunities of the Trustee hereunder including Section 6.6 and the penultimate paragraph of Section 14.5 and (D) this Article Fourteen. Subject to compliance with this Article Fourteen, the 

  

 - 79 - 

 
Company may exercise its option under this Section 14.2 notwithstanding the prior exercise of its option under Section 14.3 with respect to such
Securities and any related coupons. 
 Section 14.3 Covenant Defeasance. Upon the Company’s exercise of the above option
applicable to this Section with respect to any Securities of or within a series, the Company shall be released from its obligations under any covenant specified pursuant to Section 3.1, with respect to such Outstanding Securities and any
related coupons on and after the date the conditions set forth in Section 14.4 are satisfied (hereinafter, “covenant defeasance”), and such Securities and any related coupons shall thereafter be deemed not to be
“Outstanding” for the purposes of any direction, waiver, consent or declaration or Act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed “Outstanding” for all
other purposes hereunder. For this purpose, such covenant defeasance means that, with respect to such Outstanding Securities and any related coupons, the Company may omit to comply with and shall have no liability in respect of any term, condition
or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of reference in any such covenant to any other provision herein or in any other document and
such omission to comply shall not constitute a Default or an Event of Default under Section 5.1(4) or Section 5.1(8) or otherwise, as the case may be, but, except as specified above, the remainder of this Indenture and such Securities and
any related coupons shall be unaffected thereby. 
 Section 14.4 Conditions to Defeasance or Covenant Defeasance. The following
shall be the conditions to application of either Section 14.2 or Section 14.3 to any Outstanding Securities of or within a series and any related coupons: 
 (1) The Company shall irrevocably have deposited or caused to be deposited with the Trustee (or another trustee satisfying the requirements of Section 6.7 who shall agree to comply with the provisions of this
Article Fourteen applicable to it) as trust funds in trust for the purpose of making the following payments, specifically pledged as security for, and dedicated solely to, the benefit of the Holders of such Securities and any related coupons,
(A) an amount (in such Currency in which such Securities and any related coupons are then specified as payable at Stated Maturity), or (B) Government Obligations applicable to such Securities (determined on the basis of the Currency in
which such Securities are then specified as payable at Stated Maturity) which through the scheduled payment of principal and interest in respect thereof in accordance with their terms will provide, not later than one day before the due date of any
payment of principal of and premium, if any, and interest, if any, under such Securities and any related coupons, money in an amount, or (C) a combination thereof, sufficient, in the opinion of a nationally recognized firm of independent public
accountants expressed in a written certification thereof delivered to the Trustee, to pay and discharge, and which shall be applied by the Trustee (or other qualifying trustee) to pay and discharge, (i) the principal of (and premium, if any)
and interest, if any, on such Outstanding Securities and any related coupons on the Stated Maturity (or Redemption Date, if applicable) of such principal (and premium, if any) or installment of interest, if any, and (ii) any mandatory sinking
fund payments or analogous payments applicable to such Outstanding Securities 

  

 - 80 - 

 
and any related coupons on the day on which such payments are due and payable in accordance with the terms of this Indenture and of such Securities and any
related coupons; provided that the Trustee shall have been irrevocably instructed to apply such money or the proceeds of such Government Obligations to said payments with respect to such Securities and any related coupons. Before such a deposit, the
Company may give to the Trustee, in accordance with Section 11.2 hereof, a notice of its election to redeem all or any portion of such Outstanding Securities at a future date in accordance with the terms of the Securities of such series and
Article Eleven hereof, which notice shall be irrevocable. Such irrevocable redemption notice, if given, shall be given effect in applying the foregoing. 
 (2) No Default or Event of Default with respect to such Securities or any related coupons shall have occurred and be continuing on the date of such deposit or, insofar as Section 5.1(7) are concerned, at any time
during the period ending on the 91st day after the date of such deposit (it being understood that this condition shall not be deemed satisfied until the expiration of such period). 
 (3) Such defeasance or covenant defeasance shall not result in a breach or violation of, or constitute a default under, any material agreement or
instrument (other than this Indenture) to which the Company or any of its Subsidiaries is a party or by which the Company or any of its Subsidiaries is bound. 
 (4) In the case of an election under Section 14.2, the Company shall have delivered to the Trustee an Opinion of Counsel stating that (x) the Company has received from, or there has been published by, the
Internal Revenue Service a ruling, or (y) since the date of execution of this Indenture, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such opinion shall confirm that, the
Holders of such Outstanding Securities and any related coupons will not recognize income, gain or loss for federal income tax purposes as a result of such election and such defeasance and will be subject to federal income tax on the same amounts, in
the same manner and at the same times as would have been the case if the deposit and such defeasance had not occurred. 
 (5) In the case of
an election under Section 14.3, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of such Outstanding Securities and any related coupons will not recognize income, gain or loss for federal
income tax purposes as a result of such covenant defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if the deposit and such covenant defeasance had not
occurred. 
 (6) Notwithstanding any other provisions of this Section, such defeasance or covenant defeasance shall be effected in compliance
with any additional or substitute terms, conditions or limitations in connection therewith pursuant to Section 3.1. 
 (7) The Company
shall have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for relating to either the defeasance under Section 14.2 or the covenant defeasance under
Section 14.3 (as the case may be) have been complied with. 
  

 - 81 - 

 Section 14.5 Deposited Money and Government Obligations to Be Held in Trust; Other Miscellaneous
Provisions. Subject to the provisions of the last paragraph of Section 10.3, all money and Government Obligations (or other property as may be provided pursuant to Section 3.1) (including the proceeds thereof) deposited with the
Trustee (or other qualifying trustee, collectively for purposes of this Section 14.5, the “Trustee”) pursuant to Section 14.4 in respect of such Outstanding Securities and any related coupons shall be held in trust and applied by
the Trustee, in accordance with the provisions of such Securities and any related coupons and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent), to the Holders of such
Securities and any related coupons of all sums due and to become due thereon in respect of principal (and premium, if any) and interest, if any, but such money need not be segregated from other funds except to the extent required by law. 

Unless otherwise specified with respect to any Security pursuant to Section 3.1, if, after a deposit referred to in Section 14.4(1) has been
made, (a) the Holder of a Security in respect of which such deposit was made is entitled to, and does, elect pursuant to Section 3.12(b) or the terms of such Security to receive payment in a Currency other than that in which the deposit
pursuant to Section 14.4(1) has been made in respect of such Security, or (b) a Conversion Event occurs as contemplated in Section 3.12(d) or 3.12(e) or by the terms of any Security in respect of which the deposit pursuant to
Section 14.4(1) has been made, the Indebtedness represented by such Security and any related coupons shall be deemed to have been, and will be, fully discharged and satisfied through the payment of the principal of (and premium, if any) and
interest, if any, on such Security as they become due out of the proceeds yielded by converting (from time to time as specified below in the case of any such election) the amount or other property deposited in respect of such Security into the
Currency in which such Security becomes payable as a result of such election or Conversion Event based on the applicable Market Exchange Rate for such Currency in effect on the third Business Day prior to each payment date, except, with respect to a
Conversion Event, for such Currency in effect (as nearly as feasible) at the time of the Conversion Event. 
 The Company shall pay and
indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or Government Obligations deposited pursuant to Section 14.4 or the principal and interest received in respect thereof other than any such tax,
fee or other charge which by law is for the account of the Holders of such Outstanding Securities and any related coupons; it being understood that the Trustee shall bear no responsibility for any such tax, fee or other charge that is imposed by law
or for the account of Holders. The foregoing sentence shall survive the termination of this Indenture and the earlier resignation or removal of the Trustee. 
 Anything in this Article Fourteen to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon Company Request any money or Government Obligations (or other property and any
proceeds therefrom) held 

  

 - 82 - 

 
by it as provided in Section 14.4 which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written
certification thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect an equivalent defeasance or covenant defeasance, as applicable, in accordance with this Article. 

Section 14.6 Reinstatement. If the Trustee or any Paying Agent is unable to apply any money in accordance with Section 14.5 with
respect to any Securities by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s obligations under this Indenture and such Securities and
any related coupons shall be revived and reinstated as though no deposit had occurred pursuant to Section 14.2 or 14.3, as the case may be, until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with
Section 14.5; provided, however, that if the Company makes any payment of principal of (or premium, if any) or interest, if any, on any such Security or any related coupon following the reinstatement of its obligations, the Company shall be
subrogated to the rights of the Holders of such Securities and any related coupons to receive such payment from the money held by the Trustee or Paying Agent.

Securities of a series, the Persons entitled to vote such specified percentage in principal amount of the Outstanding Securities of such series shall constitute a quorum. In the absence of a quorum within 30 minutes of the time appointed for any

which is less than a majority, in principal amount of the Outstanding Securities of a series may be adopted at a meeting or an adjourned meeting duly reconvened and at which a quorum is present as aforesaid by the affirmative vote of the Holders of

 Notwithstanding the foregoing provisions of this Section 15.4, if any action is to be taken at a meeting of Holders of Securities of any series with
respect to any request, demand, authorization, direction, notice, consent, waiver or other action that this Indenture expressly provides may be made, given or taken by the Holders of a specified percentage in principal amount of all Outstanding
Securities affected thereby, or of the Holders of such series and one or more additional series: 
 (a) there shall be no minimum quorum
requirement for such meeting; and 
 (b) the principal amount of the Outstanding Securities of such series that vote in favor of such
request, demand, authorization, direction, notice, consent, waiver or other action shall be taken into account in determining whether such request, demand, authorization, direction, notice, consent, waiver or other action has been made, given or
taken under this Indenture. 
 Section 15.5 Determination of Voting Rights; Conduct and Adjournment of Meetings. 
 (a) Notwithstanding any provisions of this Indenture, the Trustee may make such reasonable regulations as it may deem advisable for any meeting of Holders
of Securities of a series in regard to proof of the holding of Securities of such series and of the appointment of proxies and in regard to the appointment and duties of inspectors of votes, the submission and examination of proxies, certificates
and other evidence of the right to vote, and such other matters concerning the conduct of the meeting as its shall deem appropriate. Except as otherwise permitted or required by any such regulations, the holding of Securities shall be proved in the
manner specified in Section 1.4 and the appointment of any proxy shall be proved in the manner specified in Section 1.4 or by having the signature of the person executing the proxy witnessed or guaranteed by any trust company, bank or
banker authorized by Section 1.4 to certify to the holding of Bearer Securities. Such regulations may provide that written instruments appointing proxies, regular on their face, may be presumed valid and genuine without the proof specified in
Section 1.4 or other proof. 
 (b) The Trustee shall, by an instrument in writing appoint a temporary chairman of the meeting, unless
the meeting shall have been called by the Company or by Holders of Securities as provided in Section 15.2(b), in which case the Company or the Holders of Securities of the series calling the meeting, as the case may be, shall in like manner
appoint a temporary chairman. A permanent chairman and a permanent secretary of the meeting shall be elected by vote of the Persons entitled to vote a majority in principal amount of the Outstanding Securities of such series represented at the
meeting. 
  

 - 85 - 

 (c) At any meeting each Holder of a Security of such series or proxy shall be entitled to one vote for
each $1,000 principal amount of Outstanding Securities of such series held or represented by him (determined as specified in the definition of “Outstanding” in Section 1.1); provided, however, that no vote shall be cast or counted at
any meeting in respect of any Security challenged as not Outstanding and ruled by the chairman of the meeting to be not Outstanding. The chairman of the meeting shall have no right to vote, except as a Holder of a Security of such series or proxy.

 (d) Any meeting of Holders of Securities of any series duly called pursuant to Section 15.2 at which a quorum is present may be
adjourned from time to time by Persons entitled to vote a majority in principal amount of the Outstanding Securities of such series represented at the meeting; and the meeting may be held as so adjourned without further notice. 
 Section 15.6 Counting Votes and Recording Action of Meetings. The vote upon any resolution submitted to any meeting of Holders of Securities
of any series shall be by written ballots on which shall be subscribed the signatures of the Holders of Securities of such series or of their representatives by proxy and the principal amounts and serial numbers of the Outstanding Securities of such
series held or represented by them. The permanent chairman of the meeting shall appoint two inspectors of votes who shall count all votes cast at the meeting for or against any resolution and who shall make and file with the secretary of the meeting
their verified written reports in duplicate of all votes cast at the meeting. A record, at least in duplicate, of the proceedings of each meeting of Holders of Securities of any series shall be prepared by the Secretary of the meeting and there
shall be attached to said record the original reports of the inspectors of votes on any vote by ballot taken thereat and affidavits by one or more persons having knowledge of the facts setting forth a copy of the notice of the meeting and showing
that said notice was given as provided in Section 15.2 and, if applicable, Section 15.4. Each copy shall be signed and verified by the affidavits of the permanent chairman and secretary of the meeting and one such copy shall be delivered
to the Company, and another to the Trustee to be preserved by the Trustee, the latter to have attached thereto the ballots voted at the meeting. Any record so signed and verified shall be conclusive evidence of the matters therein stated.

 [Insert title or sufficient description of Securities to be delivered] 
 This is to certify that as of the date hereof, and except as set forth below, the above-captioned Securities held by you for our account (i) are owned by person(s) that are not citizens or residents of the United
States, domestic partnerships, domestic corporations or any estate or trust the income of which is subject to United States federal income taxation regardless of its source (“United States person(s)”), (ii) are owned by United States

 [FORM OF REVERSE OF NOTE] 
 HOLOGIC, INC. 
 2.00% Convertible Senior Notes due 2037 
 This Note is one of a duly authorized issue of Notes of the Company designated as its “2.00% Convertible Senior Notes due 2037” (herein
called the “Notes”) issued and to be issued under the Indenture (the “Base Indenture”), dated as of December 10, 2007, between the Company and Wilmington Trust Company, as Trustee (herein called the
“Trustee,” which term includes any successor trustee under the Indenture (as defined below)), as supplemented and modified by the First Supplemental Indenture (the “Supplemental Indenture” and, together with the
Base Indenture, the “Indenture”), dated as of December 10, 2007, between the Company and the Trustee, 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 Notes and of the terms upon which the Notes are, and are to be, authenticated and delivered. As provided in the Supplemental Indenture and
subject to certain limitations therein set forth, the Notes are exchangeable for a like aggregate Accreted Principal Amount of Notes of any authorized denominations as requested by the Holder surrendering the same upon surrender of the Note or Notes
to be exchanged, at the Corporate Trust Office of the Trustee. The Trustee upon such surrender by the Holder hereof and the satisfaction of any requirements therefor set forth in the Supplemental Indenture shall issue the new Notes in the requested
denominations. Additional Notes may be issued in an unlimited aggregate principal amount, subject to certain conditions specified in the Supplemental Indenture. 
 No sinking fund is provided for in the Notes. 
 In any case where any Interest Payment Date, Redemption
Date, Optional Put Repurchase Date, Fundamental Change Repurchase Date or the Maturity Date of any Note or the last date on which a Holder has the right to convert his Notes shall not be a Business Day, then (notwithstanding any other provision of
the Supplemental Indenture or of the Notes) payment of Interest or Accreted Principal Amount or conversion of the Notes need not be made on such date, but may be made on the next succeeding Business Day with the same force and effect as if made on
the Interest Payment Date, Redemption Date, Optional Put Repurchase Date or Fundamental Change Repurchase Date, or at the Maturity Date, or on such last day for conversion, provided that no Interest shall accrue for the period from and after
such Interest Payment Date, Redemption Date, Optional Put Repurchase Date, Fundamental Change Repurchase Date or the Maturity Date , as the case may be. 
 The Supplemental Indenture contains provisions permitting the Company and the Trustee in certain circumstances, without the consent of the Holders of the Notes, and in other circumstances, with the consent of the
Holders of not less than a majority in aggregate Accreted Principal Amount of the Notes at the time outstanding, evidenced as in the Supplemental Indenture provided, to execute supplemental indentures adding any provisions to or changing in any
manner or eliminating any of the provisions of the Supplemental Indenture or of any supplemental indenture or modifying in any manner the rights of the Holders of the Notes; 

  

 20 

 
provided, however, that no such supplemental indenture shall make any of the changes set forth in Section 8.02 of the Supplemental
Indenture, without the consent of each Holder of an outstanding Note affected thereby. It is also provided in the Supplemental Indenture that, prior to any declaration accelerating the maturity of the Notes, the Holders of a majority in Accreted
Principal Amount of the Notes at the time outstanding may on behalf of the Holders of all of the Notes waive any past Default or Event of Default under the Supplemental Indenture and its consequences except as provided in the Supplemental Indenture.
Any such consent or waiver by the Holder of this Note (unless revoked as provided in the Supplemental Indenture) shall be conclusive and binding upon such Holder and upon all future holders and owners of this Note and any Notes which may be issued
in exchange or substitution hereof, irrespective of whether or not any notation thereof is made upon this Note or such other Notes. 
 No
reference herein to the Supplemental Indenture and no provision of this Note or of the Supplemental Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the Accreted Principal Amount of, and
accrued and unpaid Interest on, this Note, at the place, at the respective times, at the rate and in the lawful money herein prescribed. 
 Subject to the provisions of the Supplemental Indenture, upon the occurrence of a Fundamental Change or on an Optional Put Repurchase Date, the Holder has the right, at such Holder’s option, to require the Company to repurchase all of
such Holder’s Notes or any portion thereof (in Original Principal Amounts of $1,000 or integral multiples thereof) on the Fundamental Change Repurchase Date or Optional Put Repurchase Date, as applicable, at a price equal to 100% of the
Accreted Principal Amount of the Notes such Holder elects to require the Company to repurchase, together with accrued and unpaid Interest to, but excluding the Fundamental Change Repurchase Date or Optional Put Repurchase Date, as applicable, unless
such Fundamental Change Repurchase Date or Optional Put Repurchase Date, as applicable, falls after a Regular Record Date and on or prior to the corresponding Interest Payment Date, in which case the Company shall pay the full amount of accrued and
unpaid Interest payable on such Interest Payment Date to the Holder of record at the close of business on the corresponding Regular Record Date. No later than 20 Business Days prior to each Optional Put Repurchase Date, the Company shall give notice
to each Holder (and to beneficial owners as required by applicable law) of their related repurchase right. The Company or, at the written request of the Company, the Trustee shall mail to all Holders of record of the Notes a notice of the occurrence
of a Fundamental Change and of the repurchase right arising as a result thereof after the occurrence of any Fundamental Change, but on or before the 10th calendar day following such occurrence. 
 The Holder hereof has the right, at its option, (i) upon the occurrence of certain conditions specified in the Supplemental Indenture, at any time
prior to the close of business on the Scheduled Trading Day immediately preceding September 15, 2037, or (ii) on or after September 15, 2037, at any time prior to the close of business on the second Scheduled Trading Day immediately
preceding the Maturity Date, to convert any Notes or portion thereof which is $1,000 in Original Principal Amount or an integral multiple thereof, into shares of Common Stock (or cash or combination of cash and shares of Common Stock, at the
election of the Company, as set forth in Section 12.02 of the Supplemental Indenture) or Reference Property, in 

  

 21 

 
each case at the Conversion Rate specified in the Supplemental Indenture, as adjusted from time to time as provided in the Supplemental Indenture, upon
satisfaction of certain requirements set forth in the Supplemental Indenture, including, if applicable, the surrender of this Note, together with a Notice of Conversion, a form of which is contained under Section 2.03 of the Supplemental
Indenture, as provided in the Supplemental Indenture and this Note, to the Company at the office or agency of the Company maintained for that purpose, or at the option of such Holder, the Corporate Trust Office, and, unless the shares of Common
Stock or Reference Property, as the case may be, issuable on conversion are to be issued in the same name as this Note, duly endorsed by, or accompanied by instruments of transfer in form satisfactory to the Company duly executed by, the Holder or
by his duly authorized attorney. The initial Conversion Rate shall be 12.9555 shares of Common Stock for each $1,000 in Original Principal Amount of Notes. No fractional shares of Common Stock or Reference Property, as the case may be, shall be
issued upon any conversion, but an adjustment in cash shall be paid to the Holder, as provided in the Supplemental Indenture, in respect of any fraction of such share which would otherwise be issuable upon the surrender of any Note or Notes for
conversion. No adjustment shall be made for dividends or any such shares issued upon conversion of such Notes except as provided in the Supplemental Indenture. 
 Upon due presentment for registration of transfer of this Note at the office or agency of the Company, a new Note or Notes of authorized denominations for an equal aggregate Accreted Principal Amount shall be issued
to the transferee in exchange thereof, subject to the limitations provided in the Supplemental Indenture, without charge except for any tax, assessments or other governmental charge imposed in connection therewith. 
 The Company, the Trustee, any Authenticating Agent, any Paying Agent, any Conversion Agent and any Registrar may deem and treat the registered Holder
hereof as the absolute owner of this Note (whether or not this Note shall be overdue and notwithstanding any notation of ownership or other writing hereon), for the purpose of receiving payment hereof, or on account hereof, for the conversion hereof
and for all other purposes, and neither the Company nor the Trustee nor any other authenticating agent nor any Paying Agent nor any other Conversion Agent nor any Registrar shall be affected by any notice to the contrary. All payments made to or
upon the order of such registered Holder shall, to the extent of the sum or sums paid, satisfy and discharge liability for monies payable on this Note. 
 No recourse for the payment of the Accreted Principal Amount of, or accrued and unpaid Interest on, this Note, or for any claim based hereon or otherwise in respect hereof, and no recourse under or upon any
obligation, covenant or agreement of the Company in the Supplemental Indenture or any indenture supplemental thereto or in any Note, or because of the creation of any Indebtedness represented thereby, shall be had against any incorporator,
stockholder, employee, agent, officer, director or subsidiary, as such, past, present or future, of the Company or of any successor corporation, either directly or through the Company or 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, by the acceptance hereof and as part of the consideration for the issue hereof, expressly waived and released.

  

 22 

 Terms used in this Note and defined in the Supplemental Indenture are used herein as therein defined.

 In the case of any conflict between the provisions of this Note and the Indenture, the provisions of the Indenture shall control.

 The Indenture and this Note shall be governed by and construed in accordance with the laws of the State of New York. 
 Customary abbreviations may be used in the name of a Holder or an assignee, such as TEN COM (=tenants in common), TENANT (=tenants by the entireties), JT
TEN (joint tenants with right of survivorship and not as tenants in common), CUST (=custodian), and U/G/M/A (=Uniform gift to Minors Act).

of U.S. $1,000 in excess thereof. 
 SECTION 3.06 Execution, Authentication, Delivery and Dating. 

The Notes shall be executed on behalf of the Company by its Chief Executive Officer, its President or one of its Vice Presidents, attested by its
Secretary or one of its Assistant Secretaries. The signature of any of these officers on the Notes may be manual or facsimile. 
 Notes
bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the
authentication and delivery of such Notes or did not hold such offices at the date of such Notes. 
 At any time and from time to time after
the execution and delivery of this Supplemental Indenture, the Company may deliver Notes executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Notes; and the Trustee in
accordance with such Company Order shall authenticate and deliver such Notes as provided in this Indenture and not otherwise. 
 Each Note
shall be dated the date of its authentication. 
 No Note shall be entitled to any benefit under this Supplemental Indenture or be valid or
obligatory for any purpose unless there appears on such Note a certificate of authentication substantially in the form provided for herein executed by the Trustee by manual signature, and such certificate upon any Note shall be conclusive evidence,
and the only evidence, that such Note has been duly authenticated and delivered hereunder. 
 SECTION 3.07 Global
Notes; Non-Global Notes; Book-entry Provisions. 
 (a) Global Notes 
 (i) Each Global Note issued and authenticated under this Supplemental Indenture shall be registered in the name of the Depositary
designated by the Company for such Global Note or a nominee thereof and delivered to such Depositary or a nominee thereof or custodian therefor, and each such Global Note shall constitute a single Note for all purposes of this Indenture. The Company
hereby appoints DTC as the initial Depositary. 
  

 29 

 (ii) Except for exchanges of Global Notes for definitive, non-Global Notes at the sole
discretion of the Company, no Global Note may be exchanged in whole or in part for Notes registered, and no transfer of a Global Note in whole or in part may be registered, in the name of any Person other than the Depositary for such Global Note or
a nominee thereof unless (A) such Depositary (i) has notified the Company that it is unwilling or unable to continue as Depositary for such Global Note, or (ii) has ceased to be a clearing agency registered as such under the Exchange
Act, has ceased to be a “clearing corporation” within the meaning of the Uniform Commercial Code, or announces an intention permanently to cease business or does in fact do so or (B) there shall have occurred and be continuing an
Event of Default with respect to such Global Note and the maturity of the Notes shall have been accelerated in accordance with Section 5.02 and any Holder shall have given written notice to the Company requesting the issuance of definitive
Notes. In such event set forth in clause (A) above, if a successor Depositary for such Global Note is not appointed by the Company within 90 calendar days after the Company receives such notice or becomes aware of such ineligibility, the
Company shall execute, and the Trustee, upon receipt of a Company Order directing the authentication and delivery of Notes, shall authenticate and deliver, Notes, in any authorized denominations in an aggregate principal amount equal to the Accreted
Principal Amount of such Global Note in exchange for such Global Note. 
 (iii) If any Global Note is to be exchanged for
other Notes or canceled in whole, it shall be surrendered by or on behalf of the Depositary or its nominee to the Trustee, as Registrar, for exchange or cancellation, as provided in this Article 3. If any Global Note is to be exchanged for other
Notes or canceled in part, or if another Note is to be exchanged in whole or in part for a beneficial interest in any Global Note, in each case as provided in this Article 3, then either (A) such Global Note shall be so surrendered for exchange
or cancellation, as provided in this Article 3, or (B) the Accreted Principal Amount thereof shall be reduced or increased by an amount equal to the portion thereof to be so exchanged or canceled, or equal to the principal amount of such other
Note to be so exchanged for a beneficial interest therein, as the case may be, by means of an appropriate adjustment made on the records of the Trustee, as Registrar, whereupon the Trustee, in accordance with the Applicable Procedures, shall
instruct the Depositary or its authorized representative to make a corresponding adjustment to its records. Upon any such surrender or adjustment of a Global Note, the Trustee shall, upon receipt of a Company Order, subject to this Article 3,
authenticate and deliver any Notes issuable in exchange for such Global Note (or any portion thereof) to or upon the order of, and registered in such names as may be directed by, the Depositary or its authorized representative. The Trustee shall be

  

 30 

 
entitled to receive from the Depositary the names, addresses and tax identification numbers of the Persons in whose names the Notes are to be registered
prior to such authentication and delivery. Upon the request of the Trustee in connection with the occurrence of any of the events specified in the preceding paragraph, the Company shall promptly make available to the Trustee a reasonable supply of
Notes that are not in the form of Global Notes. The Trustee shall be entitled to rely upon any order, direction or request of the Depositary or its authorized representative which is given or made pursuant to this Article 3 if such order, direction
or request is given or made in accordance with the Applicable Procedures. 
 (iv) Every Note authenticated and delivered upon
registration of transfer of, or in exchange for or in lieu of, a Global Note or any portion thereof, whether pursuant to this Article 3 or otherwise, shall be authenticated and delivered in the form of, and shall be, a registered Global Note, unless
such Note is to be registered in accordance with this Article 3 in the name of a Person other than the Depositary for such Global Note or a nominee thereof, in which case such Note shall be authenticated and delivered in definitive, fully registered
form, without interest coupons. 
 (v) The Depositary or its nominee, as registered owner of a Global Note, shall be the
Holder of such Global Note for all purposes under this Supplemental Indenture and the Notes, and owners of beneficial interests in a Global Note shall hold such interests pursuant to the Applicable Procedures. Accordingly, any such owner’s
beneficial interest in a Global Note shall be shown only on, and the transfer of such interest shall be effected only through, records maintained by the Depositary or its nominee or its Agent Members and such owners of beneficial interests in a
Global Note shall not be considered the owners or holders thereof. 
 (b) Non-Global Notes. Notes issued pursuant to
Section 3.07(a)(ii) shall be in definitive, fully registered form, without interest coupons. 
 SECTION 3.08
Persons Deemed Owners. 
 Prior to due presentment of a Note for registration of transfer, the Company, the Trustee, any Paying Agent
and any agent of the Company, the Trustee or any Paying Agent may treat the Person in whose name such Note is registered as the owner of such Note for the purpose of receiving payment of principal of and (subject to Section 3.10) Interest on
such Note and for all other purposes whatsoever, whether or not such Note be overdue, and neither the Company, the Trustee, any Paying Agent nor any agent of the Company, the Trustee or any Paying Agent shall be affected by notice to the contrary.

  

 31 

 SECTION 3.09 Mutilated, Destroyed, Lost and Stolen Notes. 
 If any mutilated Note is surrendered to the Trustee, the Company shall execute and upon receipt of a Company Order, the Trustee shall authenticate and
deliver in exchange therefor a new Note of like tenor and Accreted Principal Amount and bearing a number not contemporaneously outstanding. 
 If there shall be delivered to the Company and the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Note 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 Note has been acquired by a bona fide purchaser, the Company shall execute and upon receipt of a Company Order, the Trustee shall
authenticate and deliver, in lieu of any such destroyed, lost or stolen Note, a new Note of like tenor and principal amount and bearing a number not contemporaneously outstanding. 
 In case any such mutilated, destroyed, lost or stolen Note has become or is about to become due and payable, the Company in its discretion may, instead
of issuing a new Note, pay such Note. 
 Upon the issuance of any new Note under this Section 3.09, 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 Note issued pursuant to this Section 3.09 in lieu of any destroyed, lost or stolen Note shall constitute an original additional
contractual obligation of the Company, whether or not the destroyed, lost or stolen Note shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Supplemental Indenture equally and proportionately with any and
all other Notes duly issued hereunder. 
 The provisions of this Section 3.09 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 Notes. 
 SECTION 3.10 Payment of Interest; Interest Rights Preserved. 
 Interest on any Note which 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 Note (or one or more Predecessor Notes) is registered at the close of business on the Regular Record Date for such Interest.

 Any Interest on any Note which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date (herein called
“Defaulted 

  

 32 

 
Interest”) shall forthwith cease to be payable to the Holder 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 (a) or (b) below: 
 (a) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at the close of business on a special record date for the payment of such
Defaulted Interest (a “Special Record Date”), 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 Note and the date of the
proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements reasonably satisfactory to the
Trustee for such deposit 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 Trustee 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 and not less than 10 days after the receipt by the Trustee of the notice of the
proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, 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 at his address as it appears in the Securities Register, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the
Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Notes (or their respective Predecessor Notes) 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
in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes 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 3.10, each Note delivered under this Supplemental Indenture upon registration of transfer of or in exchange for or in lieu of any other Note shall carry the rights to Interest accrued and unpaid, and to accrue, which
were carried by such other Note, as provided for in this Indenture and the Notes. 
  

 33 

 SECTION 3.11 Cancellation. 
 All Notes surrendered for payment, registration of transfer or exchange or conversion shall, if surrendered to any Person other than the Trustee, be
delivered to the Trustee and shall be promptly cancelled by it. The Company may at any time deliver to the Trustee for cancellation any Notes previously authenticated and delivered hereunder which the Company may have acquired in any manner
whatsoever, and all Notes so delivered shall be promptly cancelled by the Trustee. No Notes shall be authenticated in lieu of or in exchange for any Notes cancelled as provided in this Section 3.11, except as expressly permitted by this
Supplemental Indenture. All cancelled Notes held by the Trustee shall be disposed of as directed by a Company Order. 
 SECTION 3.12 Computation of Interest.

twelve 30-day months.

 When (1) the Company shall deliver to the Registrar for cancellation all Notes then Outstanding not theretofore delivered to the Registrar for
cancellation or (2) all the Notes then Outstanding not theretofore delivered to the Registrar for cancellation shall have (a) been deposited for conversion and the Company shall deliver to the Holders shares of Common Stock (or, at the
election of the Company, cash or a combination of cash and shares of Common Stock) sufficient to pay all amounts owing in respect of all such Notes or (b) become due and payable on the Maturity Date, Redemption Date, Optional Put Repurchase

continuing, and the Company shall also pay or cause to be paid all other sums payable hereunder by the Company, then this Supplemental Indenture with respect to the Notes shall cease to be of further effect (except as to (i) remaining rights of
registration of transfer, substitution and exchange and conversion of Notes, (ii) rights hereunder of Holders to receive from the Trustee payments of the amounts then due, including Interest with respect to the Notes and the other rights,
duties and

obligations of Holders, as beneficiaries hereof solely with respect to the amounts, if any, so deposited with the Trustee, and (iii) the rights,
obligations and immunities of the Trustee, Authenticating Agent, Paying Agent, Conversion Agent and Registrar under this Supplemental Indenture with respect to the Notes), and the Trustee, on demand of the Company accompanied by an Officers’

provided, however, the Company hereby agrees to reimburse the Trustee, Authenticating Agent, Paying Agent, Conversion Agent and Registrar for any costs or expenses thereafter reasonably and properly incurred by the Trustee,
Authenticating Agent, Paying Agent, Conversion Agent and Registrar and to compensate the Trustee, Authenticating Agent, Paying Agent, Conversion Agent and Registrar for any services thereafter reasonably and properly rendered by the Trustee,

 SECTION 4.02 Reinstatement. 
 If the Trustee or the Paying Agent is unable to apply any money to the Holders entitled
thereto by reason of any order or judgment of any court of governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s obligations under this Supplemental Indenture with respect to the Notes shall be
revived and reinstated as though no deposit had occurred pursuant to Section 4.01 until such time as the Trustee or the Paying Agent is permitted to apply all such money in accordance with this Supplemental Indenture and the Notes to the
Holders entitled thereto; provided, however, that if the Company makes any payment of the Accreted Principal Amount of or Interest on any Note following the reinstatement of its obligations, the Company shall be subrogated to the rights of
the Holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent. 
 SECTION 4.03
Officers’ Certificate; Opinion of Counsel. 
 Upon any application or demand by the Company to the Trustee to take any action
under Section 4.01, the Company shall furnish to the Trustee an Officers’ Certificate and Opinion of Counsel stating that all conditions precedent, if any, provided for in this Supplemental Indenture relating to the proposed action have
been complied with.

 REMEDIES 
 SECTION 5.01 Events of Default. 
 “Event of Default,” wherever used herein, means any one of the following events with respect to the Notes (whatever the reason for such
Event of Default or whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body): 

(a) default in any payment of Interest on any Note when due and payable and the default continues for a period of 30 calendar days; or

 (d) failure by the Company to comply with its obligations under Section 7.01; or 
 (e) failure by the Company to comply with its notice requirements under Section 11.09(b) when due; or 
 (f) failure by the Company for 60 calendar days after written notice from the Trustee or the Holders of at least 25% aggregate Accreted
Principal Amount of the Outstanding Notes has been received by the Company to comply with any of its other agreements contained in the Notes or the Indenture; or 
 (g) default by the Company or any Subsidiary of the Company with respect to any mortgage, agreement or other instrument under which there
may be outstanding, or by which there may be secured or evidenced, any debt for money borrowed in excess of $50.0 million in the aggregate of the Company and/or any such Subsidiary of the Company, whether such debt now exists or shall hereafter be
created, which default results (i) in such debt becoming or being declared due and payable and such debt has not been discharged in full or such declaration rescinded or annulled within 30 calendar days or (ii) from a failure to pay the
principal of any such debt when due and payable at its stated maturity, upon required repurchase, upon declaration or otherwise, and such 

  

 36 

 
defaulted payments shall not have been made, waived or extended within 30 calendar days; or 
 (h) failure by the Company or any of its Significant Subsidiaries to pay any final and non-appealable judgments entered by a court of
competent jurisdiction in excess of $25.0 million (to the extent not covered by insurance to which a solvent and unaffiliated insurance company has acknowledged coverage) that are not waived, satisfied or discharged for any period of 30 calendar
days during which a stay of enforcement is not in effect; or 
 (i) the Company shall commence a voluntary case or other
proceeding seeking liquidation, reorganization or other relief with respect to the Company or any of its Significant Subsidiaries or its debts under any bankruptcy, insolvency or other similar law now or hereafter in effect or seeking the
appointment of a trustee, receiver, liquidator, custodian or other similar official of the Company or any of its Significant Subsidiaries or any substantial part of its property, or shall consent to any such relief or to the appointment of or taking
possession by any such official in an involuntary case or other proceeding commenced against it, or shall make a general assignment for the benefit of creditors, or shall fail generally to pay its debts as they become due; or 
 (j) an involuntary case or other proceeding shall be commenced against the Company or any of its Significant Subsidiaries seeking
liquidation, reorganization or other relief with respect to the Company or its debts under any bankruptcy, insolvency or other similar law now or hereafter in effect or seeking the appointment of a trustee, receiver, liquidator, custodian or other
similar official of the Company or any of its Significant Subsidiaries or any substantial part of its property, and such involuntary case or other proceeding shall remain undismissed and unstayed for a period of 60 consecutive calendar days.

 (k) For the avoidance of doubt, Section 5.1 of the Base Indenture shall not be applicable to the Notes. 
 SECTION 5.02 Acceleration of Maturity; Rescission and Annulment. 
 If an Event of Default (other than an Event of Default specified in Section 5.01(i) or Section 5.01(j) with respect to the Company) occurs and
is continuing, then in every such case (except as provided in the immediately following paragraph) the Trustee or the Holders of not less than 25% in aggregate Accreted Principal Amount of the Outstanding Notes may declare 100% of the aggregate
Accreted Principal Amount of and accrued and unpaid Interest on all the Notes 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 of 

  

 37 

 
acceleration, all principal and all accrued and unpaid Interest on the Notes shall become immediately due and payable. If an Event of Default specified in
Section 5.01(i) or Section 5.01(j) with respect to the Company occurs, the aggregate accreted principal of, and accrued and unpaid Interest, if any, on, all of the Notes shall become due and payable immediately without any declaration or
other Act of the Holders or any act on the part of the Trustee. 
 Notwithstanding the foregoing, at the election of the Company, the sole
remedy of Holders for an Event of Default specified in Section 5.01(f) relating to the failure by the Company to comply with its obligations under Section 10.06 and for any failure by the Company to comply with the requirements of
Section 314(a)(1) of the Trust Indenture Act, shall for the first 90 calendar days after the occurrence of such an Event of Default consist exclusively of the right (the “Extension Right”) to receive an extension fee on the
Notes in an amount equal to 0.25% of the principal amount of the Notes (the “Extension Fee”). If the Company elects to pay the Extension Fee as the sole remedy for an Event of Default specified in Section 5.01(f) relating to
the failure by the Company to comply with its obligations under Section 10.06 and for any failure by the Company to comply with the requirements of Section 314(a)(1) of the Trust Indenture Act, the Company (i) shall notify, in the
manner provided for in Section 1.6 of the Base Indenture, the Holders and the Trustee and Paying Agent of such election prior to the first Business Day following the date on which such Event of Default first occurs and (ii) pay the
Extension Fee, on or before the close of business on the date on which such Event of Default first occurs, on all Notes then Outstanding. Upon the Company’s failure to give such notice or to pay the Extension Fee when due, the Notes shall be
subject to acceleration as provided in the first paragraph of this Section 5.02. On and after the 91st calendar day after such Event of Default occurs, if such Event of Default is not cured or waived prior to such 91st calendar day, the Notes
shall be subject to acceleration as provided in the first paragraph of this Section 5.02. If an Extension Fee is payable under this Section 5.02, the Company shall deliver to the Trustee a certificate to that effect stating (i) the
amount of such Extension Fee that is payable and (ii) the date on which such Extension Fee 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 the Extension Fee is not payable. If the Extension Fee has been paid by the Company directly to the Holders, the Company shall deliver to the Trustee a certificate setting forth the particulars of such payment. 
 Notwithstanding the foregoing paragraph, if an Event of Default (as defined therein) occurs under any series of the Company’s debt securities (other
than the Notes) issued subsequent to the Issue Date resulting from the Company’s failure to comply with obligations similar to those contained in Section 10.06 or the requirements of Section 314(a)(1) of the Trust Indenture Act, and
such Event of Default is not subject to extension on terms similar to those set forth in the 

  

 38 

 
foregoing paragraph, then the Extension Right shall no longer apply and the Notes shall be subject to acceleration as provided in the first paragraph of this
Section 5.02. 
 This Section 5.02, however, is subject to the conditions that if, at any time after the Accreted Principal Amount
of the Notes shall have been so declared due and payable, and before any judgment or decree for the payment of the monies due shall have been obtained or entered as hereinafter provided, the Company shall pay or shall deposit with the Trustee a sum
sufficient to pay installments of accrued and unpaid Interest upon all Notes and the Accreted Principal Amount of any and all Notes that shall have become due otherwise than by acceleration (with Interest on installments of accrued and unpaid
Interest (to the extent that payment of such Interest is enforceable under applicable law) and on such Accreted Principal Amount at the rate borne by the Notes during the period of such Default) and amounts due to the Trustee pursuant
Section 6.6 of the Base Indenture, and if (1) rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (2) any and all Events of Defaults under this Supplemental Indenture with respect to such
Notes, other than the nonpayment of Accreted Principal Amount of and accrued and unpaid Interest on such Notes that shall have become due solely by such acceleration, shall have been cured or waived pursuant to Section 5.04, then and in every
such case the Holders of a majority in aggregate principal amount of the Outstanding Notes, by written notice to the Company and to the Trustee, may waive all Defaults or Events of Default with respect to the Notes and rescind and annul such
declaration and its consequences and such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver or rescission and annulment shall extend to
or shall affect any subsequent Default or Event of Default, or shall impair any right consequent thereon. 
 SECTION
5.03 Unconditional Right of Holders to Receive Principal and Interest and to Convert. 
 Notwithstanding any other provision in
this Indenture, the Holder of any Note shall have the right, which is absolute and unconditional, to receive payment of the Accreted Principal Amount of and (subject to Section 3.10) Interest on such Note on the Maturity Date, and to convert
such Note in accordance with Article 12, and to institute suit for the enforcement of any such payment and right to convert, and such rights shall not be impaired without the consent of such Holder. 
 SECTION 5.04 Waiver of Past Defaults and Rescission of Acceleration. 
 With the consent of the Holders of not less than a majority in the aggregate Accreted Principal Amount of the Outstanding Notes (including, without
limitation, consents obtained in connection with a purchase of, or tender 

  

 39 

 
offer or exchange offer for, the Notes), any past Default hereunder and its consequences may be waived on behalf of the Holders of all of the Notes, except a
Default (A) in the payment of the Accreted Principal Amount of or Interest on any Note or in the delivery of amounts due upon conversion, or (B) in respect of a covenant or provision hereof which under Article 8 cannot be modified or
amended without the consent of the Holder of each Outstanding Note affected, and rescind any such acceleration with respect to the Notes and its consequences if (1) rescission would not conflict with any judgment or decree of a court of
competent jurisdiction and (2) all existing Events of Default, other than the nonpayment of Accreted Principal Amount of and Interest on the Notes or failure to deliver amounts due upon conversion that have become due solely by such declaration
of acceleration, have been cured or waived. 
 Upon the waiver of any such Default, such Default shall cease to exist, and any Event of
Default arising therefrom shall be deemed to have been cured, for every purpose of the Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon. 
 SECTION 5.05 Waiver of Stay, Usury 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 stay, usury or extension law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of the Indenture; and the Company (to the extent that it may lawfully do so)
hereby expressly waives all benefit or advantage of any such law and covenants that it shall not hinder, delay or impede by reason of such law the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of
every such power as though no such law had been enacted. 
 SECTION 5.06 Control by Holders. 
 The Holders of a majority in aggregate Accreted Principal Amount of the Outstanding Notes 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, provided that 
 (a) such direction shall not be in conflict with any rule of law or with the Indenture; 
 (b)
the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction; and 
 (c)
the Trustee may refuse to follow any direction that conflicts with law or the Indenture, or that the Trustee determines is unduly prejudicial to the rights of any other Holder or would involve the Trustee in personal liability, 
  

 40 

 provided further that, prior to taking any action under the Indenture, the Trustee will be entitled to
indemnification satisfactory to it in its sole discretion against all losses and expenses caused by taking or not taking such action. 
 SECTION 5.07 Collection of Indebtedness and Suits for Enforcement by Trustee. 
 The Company
covenants that if: 
 (1) default is made in the payment of any Interest on any Note when such Interest becomes due and
payable and such default continues for a period of 30 days, or 
 (2) default is made in the payment of the Accreted Principal
Amount of (or premium, if any, on) any Note at the Maturity thereof, 
 the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Notes, the whole amount then due and payable on such Notes for Accreted Principal Amount and Interest, and, to the extent that payment of such Interest shall be legally enforceable, Interest on any overdue Accreted Principal Amount
and on any overdue Interest, at the rate borne by the Notes, 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 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 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 the Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy. 
 SECTION 5.08 Trustee May File Proofs of Claim. 
 In case of any judicial proceeding relative to the Company (or any
other obligor upon the Notes), its property or its creditors, the Trustee shall be entitled and empowered, by intervention in such proceeding or otherwise, to take any and all actions authorized under the Trust Indenture Act in order to have claims
of the Holders and the Trustee allowed in any such proceeding. In particular, the Trustee shall be authorized 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 authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to
the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and 

  

 41 

 
advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 6.6 of the Base Indenture. 
 No provision of the Indenture shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 
 SECTION 5.09 Trustee May Enforce Claims Without Possession of Notes. 
 All rights of action and claims under the Indenture or the Notes may be prosecuted and enforced by the Trustee without the possession of any of the Notes
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 Notes in respect of which such judgment has been recovered. 
 SECTION 5.10 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 Notes 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 under Section 6.6 of the Base Indenture; and 
 SECOND: To the payment of the amounts then due and unpaid for Accreted Principal Amount of and Interest on the Notes in respect of which
or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Notes for Accreted Principal Amount and Interest, respectively. 
 SECTION 5.11 Limitation on Suits. 
 No Holder of any Note shall have any right to institute any proceeding, judicial or otherwise, with respect to the Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless:

 (1) such Holder has previously given written notice to the Trustee of a continuing Event of Default; 
  

 42 

 (2) the Holders of not less than 25% in aggregate Accreted Principal Amount of the
Outstanding Notes 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; 
 (3) such Holder or Holders have offered to the Trustee security or indemnity satisfactory to it against any costs, liability or expense;

 (4) the Trustee for 60 calendar days after its receipt of such notice, request and offer of security or indemnity has
failed to institute any such proceeding; and 
 (5) no direction that, in the opinion of the Trustee, is inconsistent with
such written request has been given to the Trustee during such 60 calendar day period by the Holders of a majority in aggregate Accreted Principal Amount of the Outstanding Notes; 
 it being understood and intended that no one or more Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Supplemental Indenture to affect, disturb or prejudice
the rights of any other Holders, or to obtain or to seek to obtain priority or preference over any other Holders or to enforce any right under the Indenture, except in the manner herein provided and for the equal and ratable benefit of all the
Holders. 
 SECTION 5.12 Restoration of Rights and Remedies. 
 If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under the 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, subject to any determination in such proceeding, the Company, the Trustee and the Holders shall 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 5.13 Rights and Remedies Cumulative. 
 Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes in the last paragraph of Section 3.09, no right or remedy herein conferred upon or reserved to
the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be 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. 
  

 43 

 SECTION 5.14 Delay or Omission Not Waiver. 
 No delay or omission of the Trustee or of any Holder of any Note 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, as the case may be. 
 SECTION 5.15 Undertaking for Costs.

 In any suit for the enforcement of any right or remedy under the Indenture, or in any suit against the Trustee for any action taken,
suffered or omitted by it as Trustee, a court may require any party litigant in such suit to file an undertaking to pay the costs of such suit, and may assess reasonable costs, including reasonable attorneys’ fees and expenses, against any such
party litigant, in the manner and to the extent provided in the Trust Indenture Act; provided, that neither this Section 5.15 nor the Trust Indenture Act shall be deemed to authorize any court to require such an undertaking or to make
such an assessment in any suit instituted by the Company or in any suit for the enforcement of the right to convert any Note in accordance with Article 12.

 Any notice required to

date of the Accreted Principal Amount of or Interest on any of the Notes, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay all amounts payable to the Trustee under Section 6.6 of the Base
Indenture and the Accreted Principal Amount or Interest so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided and will promptly notify the Trustee of its action or failure so to act. 
 Whenever the Company shall have one or more Paying Agents, it will, prior to each due date of the Accreted Principal Amount of or Interest on any Notes,
deposit with a Paying Agent a sum sufficient to pay such amount, such sum to be held as provided by the Trust Indenture Act, and (unless such Paying 

  

 50 

 
Agent is the Trustee) the Company will promptly notify the Trustee of its action or failure so to act. 
 The Company will cause each Paying Agent other than the Trustee to execute and deliver to the Trustee an instrument in which such Paying Agent shall
agree with the Trustee, subject to the provisions of this Section 10.05, that such Paying Agent will (i) comply with the provisions of the Trust Indenture Act applicable to it as a Paying Agent and (ii) during the continuance of any
default by the Company (or any other obligor upon the Notes) in the making of any payment in respect of the Notes, upon the written request of the Trustee, forthwith pay to the Trustee all sums held in trust by such Paying Agent as such. 

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 money. 
 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 or Interest on any Note and remaining unclaimed for two years after such Accreted
Principal Amount or Interest has become due and payable shall be paid to the Company on Company Request, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Note shall thereafter, as an unsecured general
creditor, look only to the Company for payment thereof, 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 a Press Release, notice that such money remains unclaimed and that, after a
date specified therein, which shall not be less than 30 calendar days from the date of such publication, any unclaimed balance of such money then remaining will be repaid to the Company.

of the Exchange Act with the Trustee within 30 calendar days after the same are required to be filed with the Commission. Documents filed by the Company with the Commission via the EDGAR system (or any successor thereto) will be deemed filed with
the Trustee as of the time such documents are filed via EDGAR (or any successor thereto). 
  

 51 

 (b) Delivery of such reports, information and documents to the Trustee is for
informational purposes only, and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of
its covenants hereunder (as to which the Trustee is entitled to conclusively rely exclusively on an Officers’ Certificate). Notwithstanding anything to the contrary in this Section 10.06, the Company, to the extent permitted under the
Trust Indenture Act, shall not be required to deliver to the Trustee or the Holders any material for which the Company has sought and received confidential treatment by the Commission. 
 SECTION 10.07 [Reserved] 
 SECTION 10.08 Tax Treatment of Notes. 
 The Company agrees, and by acceptance of a beneficial ownership interest
in the Notes each Holder is deemed to have agreed, for United States federal income tax purposes, 
 (a) to treat the Notes as
indebtedness subject to United States Treasury Regulation Section 1.1275-4 (the “Contingent Payment Debt Regulations”) and, for purposes of the Contingent Payment Debt Regulations, to treat cash and the fair market value of any
Common Stock beneficially received by a Holder upon conversion of such Note as a contingent payment under Treasury Regulation Section 1.1275-4(b); 
 (b) to be bound by the Company’s application of the Contingent Payment Debt Regulations to the Notes, including the Company’s determination of the comparable yield and projected payment schedule, as defined
in the Contingent Payment Debt Regulations, with respect to the Notes. A Holder may obtain the issue price, issue date, comparable yield (which will be treated as the yield to maturity for United States federal income tax purposes) and projected
payment schedule by submitting a written request to the Company at the following address: Hologic, Inc., 35 Crosby Drive, Bedford, Massachusetts 01730, Attention: Investor Relations; 
 (c) that the comparable yield and the projected payment schedule are not determined for any purpose other than for the purpose of applying
Treasury Regulation Section 1.1275-4(b) to the Notes, and the comparable yield and the projected payment schedule do not constitute a projection or representation regarding the actual amounts payable on the Notes; 
 (d) to use the projected payment schedule referred to in Section 10.08(b) above, as required by United States Treasury Regulations
Section 1.1275-4(b)(4)(iv), to determine its interest accruals and adjustments as provided by United States Treasury Regulation Section 1.1275-4(b); and 
  

 52 

 (e) the Company and each Holder shall not take any position on a tax return inconsistent
with (a), (b), (c) or (d), unless otherwise required by applicable law. 
 ARTICLE 11 
 REDEMPTION AND REPURCHASE OF NOTES 
 SECTION 11.01 Right to Redeem; Notice to Trustee. 
 At any time on or after December 18, 2013, the Company may redeem any or all of the Notes, except for the Notes that the Company is required to
repurchase pursuant to Section 11.08 and Section 11.09, in cash at the Redemption Price (as defined below). 
 The redemption price
will equal 100% of the Accreted Principal Amount of the Notes being redeemed, plus accrued and unpaid Interest, if any, to, but not including, the Redemption Date (the “Redemption Price”). However, if the Redemption Date is after a
Regular Record Date and on or prior to the corresponding Interest Payment Date, the Company shall pay the full amount of accrued and unpaid Interest payable on such Interest Payment Date to the Holder of record at the close of business on the
corresponding Regular Record Date. 
 If the Company elects to redeem Notes pursuant to this Section 11.01, it shall notify the Trustee
at least 45 calendar days prior to the Redemption Date, as fixed by the Company (unless a shorter notice shall be satisfactory to the Trustee), of the Redemption Date and the Accreted Principal Amount of Notes to be redeemed. 
 Notwithstanding the foregoing, the Company may not redeem any Notes if the Company has failed to pay any Interest due on the Notes and such failure to
pay is continuing. 
 SECTION 11.02 Selection of Notes to Be Redeemed. 
 If less than all of the outstanding Notes are to be redeemed, the Trustee will select the Notes to be redeemed in Original Principal Amounts of $1,000 or
multiples of $1,000 by lot, pro rata or by another method the Trustee considers reasonable. If a portion of a Holder’s Notes is selected for redemption and such Holder converts a portion of its Notes, the converted portion will be deemed to be
of the portion selected for redemption. Provisions of this Supplemental Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption. If any Note selected for partial redemption is converted in part
before termination of the conversion right with respect to the portion of the Note so selected, the converted portion of such Note shall be deemed to be taken from the portion selected for redemption. Notes which have been converted during a 

  

 53 

 
selection of Notes to be redeemed shall be treated by the Trustee as Outstanding for the purpose of such selection. 
 SECTION 11.03 Notice of Redemption. 
 Not more than 60 calendar days but not less than 30 calendar days prior to the Redemption Date, the Company shall give a Notice of Redemption to all record Holders at their addresses set forth in the Securities
Register of the Registrar. 
 The notice shall identify the Notes to be redeemed and shall state: 
 (a) that the Holder has a right to convert the Notes called for Redemption, and the Conversion Rate then in effect; 
 (b) the Redemption Date; 
 (c) the Redemption Price; 
 (d) the name and address of each Paying Agent and Conversion
Agent; 
 (e) that Notes called for redemption must be presented and surrendered to a Paying Agent to collect the Redemption
Price; 
 (f) that Holders who wish to convert Notes must surrender such Notes for conversion no later than 5:00 p.m., New
York City time, on the Scheduled Trading Day immediately preceding the Redemption Date and must satisfy the other requirements set forth in Article 12 (which shall be specified in such notice); 
 (g) that, unless the Company defaults in making the payment of the Redemption Price, Interest on Notes called for redemption shall cease
accruing on and after the Redemption Date and subject to the provisions of Sections 11.01 and 11.04, the only remaining right of the Holder shall be to receive payment of the Redemption Price upon presentation and surrender to a Paying Agent of the
Notes; and 
 (h) if any Note is being redeemed in part, the portion of the Accreted Principal Amount of such Note to be
redeemed and that, after the Redemption Date, upon presentation and surrender of such Note, new Notes in aggregate Accreted Principal Amount equal to the unredeemed portion thereof will be issued. 
 If any of the Notes to be redeemed is in the form of a Global Security, then the Company shall modify such notice to the extent necessary to accord with
the procedures of the Depositary applicable to redemptions. At the Company’s 

  

 54 

 
written request, the Trustee shall give the notice of redemption in the Company’s name and at the Company’s expense. 
 SECTION 11.04 Effect of Notice of Redemption. 
 Once notice of redemption is mailed, Notes called for redemption become due and payable on the Redemption Date and at the Redemption Price stated in the
notice except for Notes that are covered in accordance with the terms of this Supplemental Indenture. Upon presentation and surrender to a Paying Agent, Notes called for redemption shall be paid in cash at the Redemption Price stated in the notice
and from and after the Redemption Date such Notes shall cease to bear Interest and the rights of the Holders therein shall terminate (other than the right to receive the Redemption Price). 
 SECTION 11.05 Deposit of Redemption Price. 
 Prior to 1:00 p.m., New York City time, on the Redemption Date, the Company shall deposit with a Paying Agent (or, if the Company acts as Paying Agent,
shall segregate and hold in trust) an amount of money (in immediately available funds if deposited on such Redemption Date) sufficient to pay the Redemption Price of all Notes to be redeemed on that date, other than Notes or portions thereof called
for redemption on that date which have been delivered by the Company to the Trustee for cancellation or have been converted. The Paying Agent shall as promptly as practicable return to the Company any money not required for that purpose or, if such
money is then held by the Company in trust and is not required for such purpose, it shall be discharged from the trust. 
 If the Paying
Agent holds on a Redemption Date cash sufficient to pay the Redemption Price payable on that date, then on and after such Redemption Date, such Notes (or portions thereof, as the case may be) shall cease to be outstanding, the Accreted Principal
Amount shall cease to accrete and Interest (if any) on them shall cease to accrue; provided that if such Notes are to be redeemed, notice of such redemption has been duly given pursuant to this Indenture or provision therefor satisfactory to
the Trustee has been made. 
 SECTION 11.06 Notes Redeemed in Part. 
 Upon presentation and surrender of a Note that is redeemed in part, the Company shall execute and, upon receipt of a Company Order, the Trustee shall
authenticate and deliver to the Holder, without charge, new Notes of authorized denominations as requested by such Holder in aggregate Accreted Principal Amount equal to the unredeemed portion of the Note surrendered. 
  

 55 

 SECTION 11.07 No Redemption of Notes Upon Occurrence of Acceleration.

 Notwithstanding anything herein to the contrary, the Company will not redeem any Notes on any date if the Accreted Principal Amount of the
Notes has been accelerated, and such acceleration has not been rescinded on or prior to the Redemption Date (except in the case of an acceleration resulting from a default by the Company in the payment of the Redemption Price with respect to such
Notes). 
 SECTION 11.08 Repurchase of Notes at the Option of Holders. 
 (a) Optional Put. (i) On December 13, 2013, December 15, 2017, December 15,
2022, December 15, 2027 and December 15, 2032 (each, an “Optional Put Repurchase Date”), each Holder shall have the right, at such Holder’s option, to require the Company to repurchase all of such Holder’s
Notes or any portion of the Original Principal Amount thereof that is equal to $1,000 or an integral multiple of $1,000, for cash at a repurchase price equal to 100% of the Accreted Principal Amount thereof, together with accrued and unpaid Interest
thereon to, but excluding, such Optional Put Repurchase Date (the “Optional Put Repurchase Price”) (subject to satisfaction by or on behalf of the Holder of the requirements set forth in Section 11.08(a)(iii)), unless such
Optional Put Repurchase Date falls after a Regular Record Date and on or prior to the corresponding Interest Payment Date, in which case the Company shall pay the full amount of accrued and unpaid Interest payable on such Interest Payment Date to
the Holder of record at the close of business on the corresponding Regular Record Date. 
 (ii) No later than 20 Business Days
prior to each Optional Put Repurchase Date, the Company shall give notice of the repurchase right under Section 11.08(a)(i) (an “Optional Put Repurchase Offer”) to all record Holders at their addresses set forth in the
Securities Register of the Registrar (and to beneficial owners as required by applicable law). The notice shall include a form of notice to be completed by the Holder and returned to the Company in the event that the Holder elects such right to such
repurchase (the “Optional Put Repurchase Notice”) and shall briefly state, as applicable: 
 (A) the date by
which the Optional Put Repurchase Notice must be delivered to the Paying Agent in order for a Holder to exercise the repurchase right; 
 (B) the Optional Put Repurchase Date; 
 (C) the Optional Put Repurchase Price; 
  

 56 

 (D) the name and address of the Paying Agent and the Conversion Agent; 
 (E) the Conversion Rate; 
 (F) the conversion rights, if any, of the Notes; 
 (G) that the Notes as to which an Optional
Put Repurchase Notice has been given may be converted if they are otherwise convertible pursuant to Article 12 only if the Optional Put Repurchase Notice has been withdrawn in accordance with the terms of this Supplemental Indenture; 
 (H) that the Notes must be surrendered to the Paying Agent to collect payment; 
 (I) that the Optional Put Repurchase Price for any Note as to which an Optional Put Repurchase Notice has been duly given and not
withdrawn will be paid promptly following the later of the Optional Put Repurchase Date and the time of surrender of such Note; 
 (J) the procedures the Holder must follow to exercise its put right under this Section 11.08(a); 
 (K) the
procedures for withdrawing an Optional Put Repurchase Notice; 
 (L) that, unless the Company defaults in making payment of
such Optional Put Repurchase Price, Interest on Notes surrendered for repurchase by the Company will cease to accrue on and after the Optional Put Repurchase Date; and 
 (M) the CUSIP number(s) of the Notes. 
 At the Company’s request, the Trustee shall give the Optional Put Repurchase Offer in the Company’s name and at the Company’s expense; provided, however, that the Company makes such request at
least three Business Days (unless a shorter period shall be satisfactory to the Trustee) prior to the date by which such Optional Put Repurchase Offer must be given to the Holder in accordance with this Section 11.08(a)(ii); provided,
further, that the text of the Optional Put Repurchase Offer shall be prepared by the Company. 
 (iii) A Holder may
exercise its right specified in Section 11.08(a)(i) upon delivery of a properly completed Optional Put Repurchase Notice to the Paying Agent at any time during the period beginning at 9:00 a.m., New York City time, on the date that is 20

integral multiple of $1,000 thereof; and 
 (C) that the Notes shall be repurchased by the Company pursuant to the applicable
provisions of the Notes and this Supplemental Indenture. 
 The book–entry transfer or delivery of such Note to the Paying Agent with,
or at any time after delivery of, the Optional Put Repurchase Notice (together with all necessary endorsements) at the offices of the Paying Agent shall be a condition to the receipt by the Holder of the Optional Put Repurchase Price therefor;
provided, however, that such Optional Put Repurchase Price shall be so paid pursuant to this Section 11.08(a) only if the Note so delivered to the Paying Agent shall conform in all respects to the description thereof in the related
Optional Put Repurchase Notice. 
 The Company shall repurchase from the Holder thereof, pursuant to this Section 11.08(a), a portion of
a Note, so long as the Original Principal Amount of such portion is $1,000 Original Principal Amount or an integral multiple of $1,000 Original Principal Amount. Provisions of this Supplemental Indenture that apply to the repurchase of all of a Note
also apply to the repurchase of such portion of such Note. 
 The Paying Agent shall promptly notify the Company of the receipt by it of any
Optional Put Repurchase Notice or written notice of withdrawal thereof. 
 (b) Effect of Optional Put Repurchase

receipt of cash by the Paying Agent from the Company, on the later of (1) the Optional Put Repurchase Date with respect to such Note (provided the conditions in Section 11.08(a)(iii) have been satisfied) and (2) the time of book-entry
transfer or delivery of such Note to the Paying Agent by the Holder thereof in the manner required by Section 11.08(a)(iii). Notes in respect of 

  

 58 

 
which an Optional Put Repurchase Notice has been given by the Holder thereof may not be converted pursuant to Article 12 on or after the date of the delivery
of such Optional Put Repurchase Notice unless such Optional Put Repurchase Notice has first been validly withdrawn as specified in the following paragraph. 
 An Optional Put Repurchase Notice may be withdrawn by means of a written notice of withdrawal delivered to the office of the Paying Agent in accordance with the Optional Put Repurchase Notice at any time prior to 5:00

 (i) the
Original Principal Amount of such Note with respect to which such notice of withdrawal is being submitted; 
 (ii) if
certificated Notes have been issued, the certificate numbers of the withdrawn Notes; and 
 (iii) the Original Principal
Amount, if any, of such Note which remains subject to the Optional Put Repurchase Notice, which portion must be in Original Principal amounts of $1,000 or an integral multiple of $1,000. 
 provided, however, that with respect to Global Notes, the notice must comply with the Applicable Procedures. 
 (c) Deposit of Optional Put Repurchase Price. Prior to 1:00 p.m., New York City time, on the applicable Optional Put Repurchase Date, the Company shall deposit with the Paying Agent (or if the Company or a

aggregate Optional Put Repurchase Price of all the Notes or portions thereof which are to be repurchased on such Optional Put Repurchase Date. 
 If the Paying Agent (other than the Company or an Affiliate of the Company) holds, in accordance with the terms hereof, at 1:00 p.m., New York City time, on the applicable Optional Put Repurchase Date, cash sufficient to pay the Optional
Put Repurchase Price of any Notes for which an Optional Put Repurchase Notice has been tendered and not withdrawn pursuant to Section 11.08(b), then, on and after such Optional Put Repurchase Date, such Notes will cease to be outstanding, the
Accreted Principal Amount shall cease to accrete and Interest, if any, on such Notes will cease to accrue, whether or not such Notes are delivered to the Paying Agent, and the rights of the Holders in respect thereof shall terminate (other than the
right to receive the Optional Put Repurchase Price upon delivery of such Notes, together with any necessary endorsement) and the repurchased Notes shall be cancelled. 
  

 59 

 (d) Notes Repurchased in Part. Any Certificated Note which is to be repurchased
only in part shall be surrendered at the office of the Paying Agent (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the
Holder thereof or such Holder’s attorney duly authorized in writing) and the Company shall execute and upon receipt of a Company Order the Trustee shall authenticate and deliver to the Holder of such Note, without charge, new Notes, of any
authorized denomination as requested by such Holder in aggregate Accreted Principal Amount equal to, and in exchange for, the portion of the Accreted Principal Amount of the Note so surrendered which is not repurchased. 
 (e) Covenant to Comply with Securities Laws upon Repurchase of Notes. In connection with any repurchase of the Notes pursuant to
this Section 11.08, the Company shall:

 (ii) otherwise comply
with all federal and state securities laws. 
 To the extent that the provisions of any securities laws or regulations conflict with the
provisions of this Section 11.08, the Company’s compliance with such laws and regulations shall not in and of itself cause a breach of its obligations under this Section 11.08. 
 (f) Repayment to the Company. The Paying Agent shall return to the Company any cash that remains unclaimed for two years, together
with Interest, if any, thereon, held by it for the payment of the Optional Put Repurchase Price; provided, however, to the extent that the aggregate amount of cash deposited by the Company pursuant to Section 11.08(c) exceeds the
aggregate Optional Put Repurchase Price of the Notes or portions thereof which the Company is obligated to repurchase on the Optional Put Repurchase Date, then, promptly after the Optional Put Repurchase Date, the Paying Agent shall return any such
excess to the Company. 
 (g) No Repurchase Upon Acceleration. Notwithstanding anything herein to the contrary, there
shall be no purchase of any Notes pursuant to this Section 11.08 if the Accreted Principal Amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to the Optional Put Repurchase Date (except in the
case of an Event of Default resulting from a default by the Company in the payment of the Optional Put Repurchase Price with respect to such Notes).

 SECTION 11.09 Right to Require Repurchase Upon a Fundamental Change.

 (a) If a Fundamental Change occurs at any time, then each Holder shall have the right, at such Holder’s option, to
require the Company to repurchase all of such Holder’s Notes or any portion of the Original Principal Amount thereof that is equal to $1,000 or an integral multiple of $1,000, for cash on the date (the “Fundamental Change Repurchase
Date”) specified by the Company that is not less than 20 calendar days and not more than 35 calendar days after the date of the Fundamental Change Repurchase Right Notice at a repurchase price equal to 100% of the Accreted Principal Amount
thereof, together with accrued and unpaid Interest thereon to, but excluding, the Fundamental Change Repurchase Date (the “Fundamental Change Repurchase Price”), unless such Fundamental Change Repurchase Date falls after a Regular
Record Date and on or prior to the corresponding Interest Payment Date, in which case the Company shall pay the full amount of accrued and unpaid Interest payable on such Interest Payment Date to the Holder of record at the close of business on the
corresponding Regular Record Date. 
 However, notwithstanding the foregoing, Holders shall not have the right to require the Company to
repurchase any Notes under this Section 11.09 based on a Fundamental Change described in clause (1), (2) or (3) of the definition thereof (and the Company shall not be required to deliver the Fundamental Change Repurchase Right Notice
incidental thereto) if at least 90% of the consideration paid for the Common Stock (excluding cash payments for fractional shares and cash payments made pursuant to dissenters’ appraisal rights and cash dividends) in a merger or consolidation
or such other transaction otherwise constituting a Fundamental Change described in clause (1) or (2) of the definition thereof consists of shares of Common Stock or American Depositary Receipts in respect of shares of Common Stock traded
on any of the New York Stock Exchange, the American Stock Exchange, the NASDAQ Global Market or the NASDAQ Global Select Market (or any of their respective successors) (or that will be so traded or quoted immediately following the completion of such
merger or consolidation or such other transaction) and, as a result of the completion of such merger or consolidation or such other transaction, the Notes become convertible into shares of such Common Stock or such American Depositary Receipts
pursuant to Section 12.10 (or cash or a combination of cash and shares of such Common Stock or such American Depositary Receipts pursuant to Section 12.10, if the Company so elects or has so elected). 
 Repurchases of Notes under this Section 11.09 shall be made, at the option of the Holder thereof, upon: 
 (i) if the Notes are held in certificated form, delivery to the Trustee (or other Paying Agent appointed by the Company) by a Holder of a
duly completed notice (the “Fundamental Change Repurchase 

  

 61 

 
Notice”) in the form set forth on the reverse of the Note or, if the Notes are held in global form, a notice that complies with the Applicable
Procedures, prior to the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date; and 
 (ii) delivery or book-entry transfer of the Notes to the Trustee (or other Paying Agent appointed by the Company) prior to the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date (together with
all necessary endorsements) at the Corporate Trust Office of the Trustee (or other Paying Agent appointed by the Company), such delivery being a condition to receipt by the Holder of the Fundamental Change Repurchase Price therefor; provided
that such Fundamental Change Repurchase Price shall be so paid pursuant to this Section 11.09 only if the Note so delivered to the Trustee (or other Paying Agent appointed by the Company) shall conform in all respects to the description thereof
in the related Fundamental Change Repurchase Notice. 
 The Fundamental Change Repurchase Notice shall state: 
 (A) if certificated, the certificate numbers of Notes to be delivered for repurchase; 
 (B) the portion of the Original Principal Amount of Notes to be repurchased, which must be $1,000 or an integral multiple thereof; and

 (C) that the Notes are to be repurchased by the Company pursuant to the applicable provisions of the Notes and this
Supplemental Indenture. 
 Any purchase by the Company contemplated pursuant to the provisions of this Section 11.09 shall be
consummated by the delivery of the consideration to be received by the Holder promptly following the later of the Fundamental Change Repurchase Date and the time of the book-entry transfer or delivery of the Note. 
 The Trustee (or other Paying Agent appointed by the Company) shall promptly notify the Company of the receipt by it of any Fundamental Change Repurchase
Notice or written notice of withdrawal thereof in accordance with the provisions of subsection (c) of this Section 11.09. 
 Any
Note that is to be repurchased only in part shall be surrendered to the Trustee (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, upon receipt of a Company Order, the Trustee shall authenticate and make available for delivery to the Holder of 

  

 62 

 
such Note without service charge, a new Note or Notes, containing identical terms and conditions, each in an authorized denomination in aggregate principal
amount equal to and in exchange for the unrepurchased portion of the principal of the Note so surrendered. 
 (b) After the
occurrence of a Fundamental Change, but on or before the 10th calendar day after the Effective Date of such Fundamental Change, the Company shall provide to all Holders of record of the Notes and the Trustee and Paying Agent a notice (the
“Fundamental Change Repurchase Right Notice”) on the occurrence of such Fundamental Change and of the resulting repurchase right, if any, at the option of the Holders arising as a result thereof. 
 Each Fundamental Change Repurchase Right Notice shall specify (if applicable): 
 (i) the events causing the Fundamental Change; 
 (ii) the date of the Fundamental Change; 
 (iii) the last date on which a Holder may exercise the repurchase right arising as a result of a Fundamental Change, if applicable; 
 (iv) the Fundamental Change Repurchase Price, if applicable; 
 (v) the Fundamental Change Repurchase Date, if applicable; 
 (vi) the name and address of the Paying Agent and the Conversion Agent, if applicable; 
 (vii) the applicable Conversion Rate and any adjustments to the applicable Conversion Rate; 
 (viii) that the Notes with respect to which a Fundamental Change Repurchase Notice has been delivered by a Holder may be converted only if
the Holder withdraws the Fundamental Change Repurchase Notice in accordance with the terms of this Supplemental Indenture; and 
 (ix) the procedures that Holders must follow to require the Company to repurchase their Notes. 
 No failure of the Company to give
the foregoing notices and no defect therein shall limit the Holders’ repurchase rights or affect the validity of the proceedings for the repurchase of the Notes pursuant to this Section 11.09. 
 (c) A Fundamental Change Repurchase Notice may be withdrawn by means of a written notice of withdrawal delivered to the Paying Agent in
accordance with the Fundamental Change Repurchase Right Notice at any time 

  

 63 

 
prior to the close of business on the Business Day prior to the Fundamental Change Repurchase Date, specifying: 
 (i) the Original Principal Amount of the Notes with respect to which such notice of withdrawal is being submitted; 
 (ii) if certificated Notes have been issued, the certificate numbers of the withdrawn Notes, and 
 (iii) the Original Principal Amount, if any, of such Note that remains subject to the original Fundamental Change Repurchase Notice, which
portion must be in Original Principal Amounts of $1,000 or an integral multiple of $1,000; 
 provided, however, that if the Notes are not in
certificated form, the notice must comply with the Applicable Procedures. 
 (d) In connection with any repurchase of the
Notes pursuant to this Section 11.09, the Company shall 
 (i) comply with the provisions of Rule 13e-4, Rule 14e-1 (or
any successor provision) and any other tender offer rules under the Exchange Act that may then be applicable; and 
 (ii)
otherwise comply with all applicable federal and state securities laws. 
 To the extent that the provisions of any securities laws or
regulations conflict with the provisions of this Section 11.09, the Company’s compliance with such laws and regulations shall not in and of itself cause a breach of its obligations under this Section 11.09. 
 (e) On or prior to 1:00 p.m., New York City time, on the Fundamental Change Repurchase Date, the Company shall deposit with the Trustee
(or other Paying Agent appointed by the Company or if the Company is acting as its own Paying Agent, set aside, segregate and hold in trust as provided in Section 10.05) an amount of money sufficient to repurchase all of the Notes to be
repurchased on such date at the Fundamental Change Repurchase Price. Subject to receipt of funds and/or Notes by the Trustee (or other Paying Agent appointed by the Company) from the Company or the Holders, as applicable, payment for Notes
surrendered for repurchase (and not withdrawn) prior to the close of business on the Business Day prior to the Fundamental Change Repurchase Date shall be made promptly after the later of (x) the Fundamental Change Repurchase Date with respect
to such Note (provided the Holder has satisfied the conditions to the payment of the Fundamental Change Repurchase Price in this Section 11.09), and (y) the time of book-entry transfer or the 

  

 64 

 
delivery of such Note to the Trustee (or other Paying Agent appointed by the Company) by the Holder thereof in the manner required by this
Section 11.09. The Trustee shall, promptly after such payment and upon written demand by the Company, return to the Company any funds in excess of the Fundamental Change Repurchase Price. 
 (f) Subject to a Holder’s right to receive Interest on the related Interest Payment Date where the Fundamental Repurchase Date falls
between a Regular Record Date and the Interest Payment Date to which it relates, if the Trustee (or other Paying Agent appointed by the Company) holds money sufficient to repurchase on the Fundamental Change Repurchase Date all the Notes or portions
thereof that are to be purchased as of the Business Day following the Fundamental Change Repurchase Date, then on and after the Fundamental Change Repurchase Date (i) such Notes shall cease to be outstanding, (ii) the Accreted Principal
Amount shall cease to accrete, (iii) Interest shall cease to accrue on such Notes, and (iv) all other rights of the Holders of such Notes shall terminate, whether or not book-entry transfer of the Notes has been made or the Notes have been
delivered to the Trustee or Paying Agent, other than the right to receive the Fundamental Change Repurchase Price upon delivery of the Notes. 
 ARTICLE 12 
 CONVERSION OF NOTES 
 SECTION 12.01 Conversion Privilege and Conversion Rate. 
 (a) Subject to the conditions described in clauses (i), (ii), (iii) and (iv) below, and upon compliance with the provisions of
this Article 12, a Holder shall have the right, at such Holder’s option, to convert all or any portion (if the portion to be converted is $1,000 in Original Principal Amount or an integral multiple thereof) of any Notes at any time prior to the
close of business on the Scheduled Trading Day immediately preceding September 15, 2037, into shares of Common Stock (or, at the election of the Company, cash or a combination of cash and shares of Common Stock as described herein) at a rate of
12.9555 shares of Common Stock (subject to adjustment by the Company as provided in Sections 12.01(e) and 12.04 hereof) per $1,000 in Original Principal Amount of the Notes (the “Conversion Rate”) under the circumstances and during
the periods set forth below. On and after September 15, 2037 regardless of the conditions described in clauses (i), (ii), (iii) and (iv) below, and upon compliance with the provisions of this Article 12, a Holder shall have the right,
at such Holder’s option, to convert all or any portion (if the portion to be converted is $1,000 in Original Principal Amount or an integral multiple thereof) of any Notes at the applicable Conversion Rate at any time prior to the close of
business on the second Scheduled Trading Day immediately preceding the Maturity Date. 
  

 65 

 (i) The Notes shall be convertible prior to September 15, 2037, during the five
Business Day period after any five consecutive Trading Day period (as used in this Section 12.01(a)(i), the “Measurement Period”) in which the Trading Price per $1,000 in Original Principal Amount of the Notes for each Trading
Day of such Measurement Period was less than 98% of the product of the Last Reported Sale Price of the Common Stock on such Trading Day and the applicable Conversion Rate in effect on such Trading Day, as determined by the Trustee and subject to
compliance with the procedures and conditions described below concerning the Trustee’s obligation to make such determination (the “Trading Price Condition”). If a Holder provides the Company with reasonable evidence that the
Trading Price per $1,000 in Original Principal Amount of the Notes would be less than 98% of the product of (a) the then-applicable Conversion Rate of the Notes and (b) the Last Reported Sale Price at such time, then the Company shall
instruct in writing the Trustee to determine the Trading Price of the Notes beginning on the next Trading Day and on each successive Trading Day until the date on which the Trading Price per $1,000 in Original Principal Amount of the Notes is
greater than or equal to 98% of the product of (a) the then-applicable Conversion Rate of the Notes and (b) the Last Reported Sale Price (as provided to the Trustee by the Company on each such date). If the Trading Price Condition has been
met in accordance with the foregoing, the Company shall so notify the Holders of the Notes and the Trustee. If, at any time after the Trading Price Condition has been met in accordance with the foregoing, the Trading Price per $1,000 in Original
Principal Amount of the Notes is greater than 98% of the product of (a) the then-applicable Conversion Rate of the Notes and (b) the Last Reported Sale Price on such date, the Company shall so notify the Holders of the Notes and the
Trustee, and the Trustee shall have no further obligation to determine the Trading Price of the Notes unless requested by the Company to do so again in writing pursuant to this Section 12.01(a)(i). Furthermore, if the Company does not, when
obligated to do so pursuant to this clause (i), instruct the Trustee to determine the Trading Price of the Notes, or if the Company so instructs the Trustee, but the Trustee does not make such determination, then the Trading Price per $1,000 in
Original Principal Amount of the Notes shall be deemed to be less than 98% of the product of (a) the then-applicable Conversion Rate of the Notes and (b) the Last Reported Sale Price on such date. 
 (ii) The Notes shall be convertible prior to September 15, 2037, during any calendar quarter after the calendar quarter ending
December 31, 2007 (and only during such calendar quarter), if the Last Reported Sale Price of the Common Stock for 20 or more Trading Days in a period of 30 consecutive Trading Days ending on the last Trading Day of the immediately preceding
calendar quarter exceeds 130% of the applicable 

  

 66 

 
Conversion Price in effect on the last Trading Day of the immediately preceding calendar quarter. For each calendar quarter, the Company, or at the written
request of the Company, the Conversion Agent, will determine if the Notes are convertible as the result of the satisfaction of the condition in this Section 12.01(a)(ii) in the preceding calendar quarter and the Company will promptly notify the
Holders and the Trustee if this condition was satisfied. 
 (iii) In the event the Company calls the Notes for redemption
pursuant to Section 11.01, the Notes shall be convertible pursuant to subsection (f) of this Section. 
 (iv) The
Notes shall be convertible prior to September 15, 2037, as provided in subsections (b), (c) and (d) of this Section 12.01. 
 (b) In the event that the Company elects to: 
 (i) distribute to all or substantially all
holders of Common Stock any rights or warrants entitling them, for a period of not more than 60 calendar days after the record date for such distribution, to subscribe for or purchase Common Stock at a price per share less than the Last Reported
Sale Price of the Common Stock for the Trading Day immediately preceding the declaration date of such distribution; or 
 (ii)
distribute to all or substantially all holders of Common Stock assets (including cash) or debt securities of the Company or certain rights to purchase the Company’s securities, which distribution has a per share value (as determined by the
Board of Directors) exceeding 10% of the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the date of declaration of such distribution, 
 the Company shall notify Holders and the Trustee in writing with respect to any distribution referred to in either clause (i) or clause (ii) above and of the resulting conversion right no later than the 35th
Scheduled Trading Day prior to the Ex-Date for such distribution. Once the Company has given such notice, Holders may surrender the Notes for conversion at any time until the earlier of 5:00 p.m., New York City time, on the Business Day immediately
preceding the Ex-Date for such distribution or the date the Company announces that such distribution will not take place. A Holder may not exercise this right if such Holder is permitted to participate (as a result of holding the Notes, and at the
same time as holders of the Common Stock participate) in any distribution referred to in clause (i) or clause (ii) above as if such Holder held a number of shares of Common Stock equal to the then-applicable Conversion Rate, multiplied by
the principal amount (expressed in thousands) of Notes held by such Holder, without having to convert its Notes. 
  

 67 

 (c) If the Company is a party to a combination, merger, recapitalization,
reclassification, binding-share exchange or other similar transaction or sale or conveyance of all or substantially all of its properties and assets, in each case pursuant to which the Common Stock would be converted into cash, securities and/or
other property and that does not also constitute a Fundamental Change, then the Holders shall have the right to convert Notes at any time beginning on the effective date of such transaction and ending on the 30th Scheduled Trading Day following the
effective date of such transaction. The Company shall notify Holders and the Trustee in writing at least 10 Scheduled Trading Days prior to the anticipated effective date of any such transaction. The Board of Directors shall determine the
anticipated effective date of the transaction, and such determination shall be conclusive and binding on the Holders. 
 (d)
If the Company is a party to any transaction or event described in the definition of Fundamental Change, a Holder may surrender Notes for conversion at any time, after the Company gives the notice referred to in the last sentence of this
Section 12.01(d), from the effective date of such event until (i) the Fundamental Change Repurchase Date corresponding to such events or (ii) if there is no such Fundamental Change Repurchase Date, 30 Scheduled Trading Days following
the effective date of such transaction or event. The Company shall notify in writing, in the manner provided for in Section 1.6 of the Base Indenture, each of the Holders and the Trustee of the Fundamental Change on or before the date such
event occurs or becomes effective or, if later, within 2 Business Days after the date the Company becomes aware of such occurrence or effectiveness. 
 (e) If a Holder elects to convert Notes in connection with a Make-Whole Fundamental Change, the Conversion Rate applicable to each $1,000 in Original Principal Amount of Notes so converted shall be increased by an
additional number of shares of Common Stock (the “Additional Shares”) as described below; provided, however that no increase shall be made in the case of a transaction or event constituting a Fundamental Change
described in clauses (1) or (2) of such definition where 90% or more of the consideration for the Common Stock (excluding cash payments for fractional shares and cash payments made pursuant to dissenters’ appraisal rights) in such
transaction consists of shares of Common Stock or American Depositary Receipts in respect of shares of Common Stock traded on any of the New York Stock Exchange, the American Stock Exchange, the NASDAQ Global Market or the NASDAQ Global Select
Market (or any of their respective successors) (or that will be so traded or quoted immediately following the transaction) and as a result of such transaction or transactions the Notes become convertible (to the extent otherwise convertible into
shares of Common Stock) into cash and, if applicable, such shares of such Capital Stock or such American Depositary Receipts. Settlement of Notes tendered for conversion to which Additional 

  

 68 

 
Shares shall be added to the Conversion Rate as provided in this subsection (e) shall be settled pursuant to Section 12.02(e). For purposes of this
subsection (e), a conversion shall be deemed to be “in connection with” such Make-Whole Fundamental Change if such conversion occurs on or after the Make-Whole Reference Date until the related Fundamental Change Repurchase Date for
such Make-Whole Fundamental Change or, if there is no such Fundamental Change Repurchase Date, 30 Scheduled Trading Days following the Make-Whole Reference Date, but in no event later than the second Scheduled Trading Day prior to the Maturity of
the Notes. The Company will notify Holders and the Trustee in writing of the occurrence of any Make-Whole Fundamental Change applicable to this subsection (e) on the Make-Whole Reference Date. 
 (i) The number of Additional Shares by which the Conversion Rate will be increased in the event of a Make-Whole Fundamental Change shall
be determined by the Company by reference to the table attached as Schedule A hereto, based on the Make-Whole Reference Date and the Stock Price; provided that, for purposes of determining the number of Additional Shares, the
Make-Whole Reference Date of a transaction described in clause (1) or (2) of the definition of Fundamental Change shall be deemed to be the earlier of (x) the date on which such transaction occurs or becomes effective and (y) the
date of the first public announcement of such transaction by the Company or the counterparty to the transaction; provided, that if the actual Stock Price is between two Stock Price amounts in the table or the Make-Whole Reference Date is
between two Make-Whole Reference Dates in the table, the number of Additional Shares by which the Conversion Rate will be increased shall be determined by a straight-line interpolation between the number of Additional Shares set forth for the next
higher and next lower Stock Price amounts and the two nearest Make-Whole Reference Dates, as applicable, based on a 365-day year; provided, further, that if (1) the Stock Price is greater than $350.00 per share of Common Stock (subject
to adjustment in accordance with clause (ii) below), no adjustments will be made in the Conversion Rate, and (2) the Stock Price is less than $61.75 per share (subject to adjustment in accordance with clause (ii) below), no
adjustments will be made in the Conversion Rate. Notwithstanding the foregoing, in no event shall the Conversion Rate exceed 16.1943 shares per $1,000 in Original Principal Amount of Notes (subject to adjustment in the same manner as set forth in
Section 12.04). In addition, if Holders convert their Notes prior to any applicable Make-Whole Reference Date, and the related Make-Whole Fundamental Change does not occur, Holders will not be entitled to an increased Conversion Rate in
connection with such conversion. 
  

 69 

 (ii) The Stock Prices set forth in the first row of the tables in Schedule A
hereto shall be adjusted by the Company as of any date on which the Conversion Rate of the Notes is adjusted (except pursuant to this Section 12.01(e)). The adjusted Stock Prices shall equal the Stock Prices applicable immediately prior to such
adjustment, multiplied by a fraction, the numerator of which is the applicable Conversion Rate in effect immediately prior to the adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so
adjusted. The number of Additional Shares within the table shall be adjusted in the same manner as the Conversion Rate as set forth in Section 12.04 (other than by operation of an adjustment to the Conversion Rate by adding Additional Shares).

 (f) In the event the Company calls the Notes for redemption pursuant to Section 11.01, the Notes shall be convertible
until 5:00 p.m., New York City time, on the Business Day preceding the applicable Redemption Date (after which time the Holders’ right to convert will expire unless the Company defaults in the payment of the applicable Redemption Price).

 SECTION 12.02 Exercise of Conversion Privilege. 
 (a) The Company shall satisfy the Conversion Obligation by delivering, as applicable: 
 (i) on or before the third Business Day immediately following the Conversion Date, a number of shares of Common Stock equal to
(i) (A) the aggregate Original Principal Amount of Notes to be converted, divided by (B) 1,000 multiplied by (ii) the Conversion Rate in effect on the relevant Conversion Date; 
 (ii) on the third Business Day immediately following the last day of the related Observation Period, for each $1,000 in Original Principal
Amount of Notes tendered for conversion, cash in an amount equal to the sum of the Daily Conversion Values for each of the 30 VWAP Trading Days during the related Observation Period; or 
 (iii) on the third Business Day immediately following the last day of the related Observation Period, for each $1,000 in Original
Principal Amount of Notes tendered for conversion, cash and shares of Common Stock, if any, equal to the sum of the Daily Settlement Amounts for each of the 30 VWAP Trading Days during the related Observation Period, 
 in each case subject, if applicable, to Section 12.02(c) and Section 12.03 hereof. The applicable settlement method for any particular conversion of Notes

  

 70 

 
(pursuant to clause (i), (ii) or (iii) above) shall be determined pursuant to Section 12.02(b). 
 (b) Prior to the 35th Scheduled Trading Day prior to the Maturity Date, the Company may elect to settle conversions in respect of the
Conversion Obligation pursuant to clause (i), (ii) or (iii) of Section 12.02(a) (or, if the Company has made the Net Share Settlement Election on or prior to the applicable Conversion Date, clause (ii) or (iii) of
Section 12.02(a)) by providing notice (a “Consideration Notice”) to the converting Holders through the Trustee (by requesting in writing that the Trustee provide the Consideration Notice) of the applicable settlement method no
later than the second Business Day immediately following the related Conversion Date or by making the Net Share Settlement Election. If the Consideration Notice designates settlement pursuant to clause (iii) of Section 12.02(a), it will
state the Specified Dollar Amount. If the Company does not provide a Consideration Notice in respect of a conversion and has not made the Net Settlement Election, conversion of the applicable Notes will be settled pursuant to clause (i) of
Section 12.02(a). 
 At any time prior to the 35th Scheduled Trading Day prior to the Maturity Date, the Company may deliver a one-time
Consideration Notice to the Holders designating the settlement method (clause (i), (ii) or (iii) of Section 12.02(a) or, if the Company has made the Net Share Settlement Election, clause (ii) or (iii) of
Section 12.02(a)) for all conversions that occur on or after the 35th Scheduled Trading Day prior to the Maturity Date. For conversions that occur on or after the 35th Scheduled Trading Day prior to the Maturity Date, 
 (1) if the Company has not delivered the one-time Consideration Notice referred to in this Section 12.02(b) and has not made the Net Share
Settlement Election, conversion of the applicable Notes will be settled in accordance with clause (i) of Section 12.02(a); and 
 (2) if the Company has not delivered the one-time Consideration Notice referred to in this Section 12.02(b) and has made the Net Share Settlement Election, conversion of the applicable Notes will be settled in accordance with clause
(iii) of Section 12.02(a), and the Specified Dollar Amount for all such conversions will be deemed to be the Accreted Principal Amount as of the Maturity Date. 
 At any time prior to the 35th Scheduled Trading Day prior to the Maturity Date, the Company may deliver a one-time irrevocable notice to the Holders electing to settle all conversions of the Notes from the date of
such notice pursuant to either clause (ii) or (iii) of Section 12.02(a) (the “Net Share Settlement Election”). If the Company has made the Net Share Settlement Election and elected to settle all conversions pursuant
to clause (iii) above, the notice of such Net Share Settlement Election shall state the Specified Dollar Amount applicable to all conversions of such Notes, which shall be at least the 

  

 71 

 
Accreted Principal Amount of such Notes as of the Conversion Date, provided that the Specified Dollar Amount applicable to all conversions of such
Notes converted on or after the 35th Scheduled Trading Day prior to the Maturity Date shall be at least the Accreted Principal Amount of such Notes as of
the Maturity Date. Upon making the Net Share Settlement Election, the Company will issue a Press Release or post such information on its website, or otherwise publicly disclose such information, and will provide written notice to the Holders in the
manner contemplated by this Supplemental Indenture, including through the facilities of the DTC. 
 The Company will settle all
conversions by Holders converting on the same Trading Day in the same manner. Except for all conversions that occur on or after the 35th Scheduled Trading Day prior to the Maturity Date and, if the Company has made the Net Share Settlement Election
(to the extent such election restricts the method of conversion), all conversions that occur on or after the date of such Net Share Settlement Election, the Company will have no obligation to settle Conversion Obligations arising on different
Trading Days in the same manner. 
 (c) Notwithstanding any of the foregoing to the contrary, in lieu of settling the
Conversion Obligation in the manner set forth in Section 12.02(a) above, the Company may elect (the “Exchange Election”) to direct the Conversion Agent in writing to surrender, on or prior to the second Business Day following
the Conversion Date, Notes tendered for conversion to a financial institution designated by the Company (the “Financial Institution”) for exchange in lieu of conversion. In order to accept any Notes surrendered for conversion, the
Financial Institution must agree to timely deliver, in exchange for such Notes, the shares of Common Stock and/or cash which would otherwise be due upon conversion as set forth in Section 12.02(a) (the “Conversion
Consideration”). If the Company makes the Exchange Election, the Company will, by the close of business on the second Business Day following the relevant Conversion Date, notify Holders surrendering Notes for conversion that the Company has
made the Exchange Election and will notify the Financial Institution of the Conversion Consideration to be delivered pursuant to Sections 12.02(a) and (b) and the relevant deadline for delivery of the Conversion Consideration. Any Notes
exchanged by the Financial Institution will remain outstanding. If the Financial Institution agrees to accept Notes for exchange but does not timely deliver the related Conversion Consideration, or if such Financial Institution does not accept such
Notes for exchange, the Company will deliver the Conversion Consideration as if the Company had not made the Exchange Election. 
 (d) Before any Holder of a Note shall be entitled to convert the same as set forth above, such Holder shall (1) in the case of a Global Note, comply with the procedures of the Depositary in effect at that time and, if required, pay
funds equal to Interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in subsection (i) of this Section 12.02(a) and, if required, 

  

 72 

 
pay all taxes or duties, if any, in connection therewith and (2) in the case of a Note issued in certificated form, (A) complete and manually sign
and deliver an irrevocable written notice to the Conversion Agent in the form set forth under Section 2.03 (or a facsimile thereof) (a “Notice of Conversion”) at the office of the Conversion Agent and shall state in writing
therein the Accreted Principal Amount of Notes to be converted and the name or names (with addresses) in which such Holder wishes the certificate or certificates for any shares of Common Stock, if any, to be delivered upon settlement of the
Conversion Obligation to be registered, (B) surrender such Notes, duly endorsed to the Company or in blank (and accompanied by appropriate endorsement and transfer documents), at the office of the Conversion Agent, (C) if required, pay
funds equal to Interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in subsection (i) of Section 12.02(a), and (D) if required, pay all taxes or duties, if any, in connection therewith.
As used herein, “Conversion Date” shall mean the date that the Holder has complied with the requirements set forth in this subsection (d). 
 No Notice of Conversion with respect to any Notes may be tendered by a Holder thereof if such Holder has also tendered a Fundamental Change Repurchase Notice and not validly withdrawn such Fundamental Change
Repurchase Notice in accordance with the applicable provisions of Section 11.09. 
 If more than one Note shall be surrendered for
conversion at one time by the same Holder, the Conversion Obligation with respect to such Notes, if any, that shall be payable upon conversion shall be computed on the basis of the aggregate Accreted Principal Amount of the Notes (or specified
portions thereof to the extent permitted thereby) so surrendered. 
 (e) Delivery of the amounts owing in satisfaction of the
Conversion Obligation shall be made by the Company in no event later than the date specified in subsection (a) of this Section 12.02, except to the extent specified in subsection (b) of this Section 12.02. The Company shall make
such delivery by issuing, or causing to be issued, and delivering to such Holder, or such Holder’s nominee or nominees, certificates or a book-entry transfer through the Depositary for the number of full shares of Common Stock to which such
Holder shall be entitled as part of such Conversion Obligation (together with any cash in lieu of fractional shares). 
 (f)
In case any Note shall be surrendered for partial conversion, the Company shall execute and the Trustee shall, as provided in a Company Order, authenticate and deliver to or upon the written order of the Holder of the Note so surrendered, without
charge to such Holder, a new Note or Notes in authorized denominations in an aggregate Accreted Principal Amount equal to the unconverted portion of the surrendered Notes. 
  

 73 

 (g) If a Holder submits a Note for conversion, the Company shall pay all documentary,
stamp or similar issue or transfer tax due, if any, which may be imposed by the United States or any political subdivision thereof or taxing authority thereof or therein with respect to the issuance of shares of Common Stock, if any, upon the
conversion. However, the Holder shall pay any such tax which is due because the Holder requests any shares of Common Stock to be issued in a name other than the Holder’s name. The Company may refuse to deliver the certificates representing the
shares of Common Stock being issued in a name other than the Holder’s name until the Company receives a sum sufficient to pay any tax which will be due because the shares are to be issued in a name other than the Holder’s name. Nothing
herein shall preclude any tax withholding required by law or regulations. 
 (h) Except as provided in Section 12.04, no
adjustment shall be made for dividends on any shares issued upon the conversion of any Note as provided in this Article 12. 
 (i) Upon the conversion of an interest in a Global Note, the Trustee, or the Custodian at the direction of the Trustee, shall make a notation on such Global Note as to the reduction in the principal amount represented thereby. The Company
shall notify the Trustee in writing of any conversion of Notes effected through any Conversion Agent other than the Trustee. 
 (j) Upon conversion, a Holder shall not receive any separate cash payment for accrued and unpaid Interest except as set forth below. The Company’s settlement of the Conversion Obligation as described above shall be deemed to satisfy
its obligation to pay the principal amount of the Notes and accrued and unpaid Interest to, but not including, the Conversion Date. As a result, accrued and unpaid Interest on the Notes to, but not including, the Conversion Date shall be deemed to
be paid in full rather than cancelled, extinguished or forfeited. Notwithstanding the preceding sentence, if Notes are converted after 5:00 p.m., New York City time, on a Regular Record Date, Holders of such Notes as of 5:00 p.m., New York City
time, on such Regular Record Date shall receive the Interest payable on such Notes on the corresponding Interest Payment Date notwithstanding the conversion. Notes surrendered for conversion during the period from 5:00 p.m., New York City time, on
any Regular Record Date to 9:00 a.m., New York City time, on the corresponding Interest Payment Date must be accompanied by payment of an amount in cash equal to the Interest payable, on such Interest Payment Date, on the Notes so converted;
provided, however, that no such payment need be made (i) if the Company has specified a Fundamental Change Repurchase Date that is after a Regular Record Date and on or prior to the corresponding Interest Payment Date; or
(ii) to the extent of any overdue Interest remains unpaid at the time of conversion with respect to such Note. Except as described above, no payment or adjustment shall be made for accrued Interest on converted Notes. The Company shall not be
required to convert any Notes that are surrendered 

  

 74 

 
for conversion without payment of Interest as required by this Section 12.02(j). The Conversion Rate will not be adjusted for accrued and unpaid
Interest or accreted principal in excess of the $1,000 Original Principal Amount of the Notes. 
 SECTION 12.03
Fractions of Shares. 
 No fractional shares of Common Stock shall be issued upon conversion of any Note or Notes. If more than one
Note shall be surrendered for conversion at one time by the same Holder, the number of full shares which shall be issuable upon conversion thereof shall be computed on the basis of the aggregate Accreted Principal Amount of the Notes (or specified
portions thereof) so surrendered. Instead of any fractional share of Common Stock that would otherwise be issuable upon conversion of any Note or Notes (or specified portions thereof), the Company shall calculate and pay a cash adjustment in respect
of such fraction (calculated to the nearest 1/100th of a share) based on the Daily VWAP on (x) the last VWAP Trading Day of the applicable Observation Period in the case of conversions following any Net Share Settlement Election or conversions
settled in accordance with clause (iii) of Section 12.02(a) above and (y) the Conversion Date (or, if the Conversion Date is not a Trading Day, the next following Trading Day) if the Company elects to settle in accordance with clause
(i) of Section 12.02(a) above. 
 SECTION 12.04 Adjustment of Conversion Rate. 
 The Conversion Rate shall be adjusted from time to time by the Company as follows; provided that the Company shall not make any adjustments to the
Conversion Rate if Holders of the Notes participate (as a result of holding the Notes, and at the same time as holders of the Common Stock participate) in any of the transactions described below as if such Holders held a number of shares of Common
Stock equal to the applicable Conversion Rate, multiplied by the Original Principal Amount (expressed in thousands) of Notes held by such Holders, without having to convert their Notes: 
 (a) In case the Company shall issue shares of Common Stock as a dividend or distribution on shares of Common Stock, or shall effect a
share split or share combination, the Conversion Rate shall be adjusted based on the following formula: 
  

													
		 	 CR’
	 		 	 =
	 	 CR0 ×
	 	 OS’
	  	
		 		 		 		 		 	OS0	  	

 where, 
  

 75 

 CR0 = the Conversion Rate in effect immediately prior to the close of business on the Ex-Date for such dividend or distribution or the effective date of such share split or combination,
as the case may be; 
 CR’ = the Conversion Rate in effect immediately after the close of business on the Ex-Date for such
dividend or distribution or the effective date of such share split or combination, as the case may be; 
 OS0 = the number of shares of Common Stock outstanding immediately prior to the Ex-Date for such dividend or distribution
or the effective date of such share split or combination, as the case may be; and 
 OS’ = the number of shares of Common Stock
that will be outstanding as of the “Ex-Date” for such dividend or distribution and immediately after giving effect to such dividend or distribution or immediately after the effective date of such share split or combination, as the case may
be. 
 Such adjustment shall become effective immediately after the close of business on the Ex-Date fixed for such dividend or distribution,
or the effective date for such share split or share combination. If any dividend or distribution of the type described in this Section 12.04(a) is declared but not so paid or made, or the outstanding shares of Common Stock are not split or
combined, as the case may be, the Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution, or split or combine the outstanding shares of Common Stock, as
the case may be, to the Conversion Rate that would then be in effect if such dividend, distribution, share split or share combination had not been declared. 
 (b) In case the Company shall distribute to all or substantially all holders of its outstanding shares of Common Stock any rights or
warrants entitling them for a period expiring not more than 60 calendar days after the Ex-Date of such distribution to subscribe for or purchase shares of Common Stock at a price per share less than the Last Reported Sale Price of the Common Stock
on the Trading Day immediately preceding the declaration date of such distribution, the Conversion Rate shall be adjusted based on the following formula; provided that the Conversion Rate will be readjusted to the extent that such rights or
warrants are not exercised prior to their expiration: 
  

													
		 	 CR’
	 		 	 =
	 	 CR0 ×
	 	 (OS0 + X)
	  	
		 		 		 		 		 	(OS0 + Y)	  	

 where, 
 CR0 =
the Conversion Rate in effect immediately prior to the close of business on the Ex-Date for such distribution; 
  

 76 

 CR’ = the Conversion Rate in effect immediately after the close of business on the Ex-Date for such
distribution; 
 OS0 = the number of shares of Common Stock outstanding immediately prior to the Ex-Date for such distribution; 
 X = the total number of shares of Common Stock issuable pursuant to such rights or warrants; and 
 Y = the number of shares of
Common Stock equal to the aggregate price payable to exercise such rights or warrants divided by the average of the Daily VWAP of Common Stock over the 10 consecutive VWAP Trading Day period ending on the VWAP Trading Day immediately preceding the
Ex-Date for such distribution. 
 Such adjustment shall be successively made whenever any such rights or warrants are distributed and shall
become effective immediately after the close of business on the Ex-Date for such distribution. The Company shall not issue any such rights or warrants in respect of shares of the Common Stock held in treasury by the Company. To the extent that
shares of the Common Stock are not delivered after the expiration of such rights or warrants, the Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect had the adjustments made upon the issuance of such rights or
warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered. If such rights or warrants are not so issued, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in
effect if such Ex-Date for such distribution had not been fixed. 
 In determining whether any rights or warrants entitle the holders to
subscribe for or purchase shares of Common Stock at less than such Last Reported Sale Price, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration received by the Company
for such rights or warrants and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors. 
 (c) In case the Company shall, by dividend or otherwise, distribute to all or substantially all holders of its Common Stock shares of any
class of Capital Stock of the Company, evidences of its Indebtedness or other assets or property of the Company excluding (i) dividends and distributions covered by subsections (a), (b) or (d) of this Section 12.04 and
distributions described below in this subsection (c) with respect to Spin-Offs) (any of such shares of Capital Stock, Indebtedness, or other asset or property hereinafter in this subsection (c) called the “Distributed
Property”), then, in each such case the Conversion Rate shall be adjusted based on the following formula: 
  

 77 

													
		 	 CR’
	 		 	 =
	 	 CR0 ×
	 	 SP0

	  	
		 		 		 		 		 	SP0 – FMV	  	

 where, 
 CR0 =
the Conversion Rate in effect immediately prior to the close of business on the Ex-Date for such distribution; 
 CR’ = the
Conversion Rate in effect immediately after the close of business on the Ex-Date for such distribution; 
 SP0 = the average of the Daily VWAP of Common Stock over the ten (10) consecutive VWAP Trading Day period ending on
the VWAP Trading Day immediately preceding the Ex-Date for such distribution; and 
 FMV = the fair market value as determined by the
Board of Directors or a committee thereof of the Distributed Property with respect to each outstanding share of Common Stock on the Ex-Date for such distribution. 
 Such adjustment shall become effective immediately after the close of business on the Ex-Date for
such distribution; provided that if “FMV” as set forth above is equal to or greater than “SP0” as set forth above, in lieu of
the foregoing adjustment, adequate provision shall be made so that each Holder has the right to receive, for each $1,000 in principal amount of Notes, the amount of Distributed Property such Holder would have received had such Holder owned a number
of shares of Common Stock equal to the Conversion Rate on the Ex-Date for such distribution, without being required to convert the Notes. If such distribution is not so paid or made, the Conversion Rate shall again be adjusted to be the Conversion
Rate that would then be in effect if such dividend or distribution had not been declared. If the Board of Directors determines “FMV” for purposes of this Section 12.04(c) by reference to the actual or when issued trading market for
any securities, it must in doing so consider the prices in such market over the same period used in computing the Last Reported Sale Prices of the Common Stock over the ten consecutive Trading Day period ending on the Trading Day immediately
preceding the Ex-Date for such distribution. 
 With respect to an adjustment pursuant to this subsection (c) where there has
been a payment of a dividend or other distribution on the Common Stock, in shares of Capital Stock of any class or series, or similar equity interest, of or relating to a Subsidiary or other business unit (a “Spin-Off”), the
Conversion Rate in effect immediately before 5:00 p.m., New York City time, on the 10th Trading Day immediately following, and including, the effective date of the Spin-Off shall be increased based on the following formula: 
  

													
		 	 CR’
	 		 	 =
	 	 CR0 ×
	 	 FMV0 + MP0
	  	
		 		 		 		 		 	MP0	  	

  

 78 

 where, 
 CR0 =
the Conversion Rate in effect immediately prior to the close of business on the 10th Trading Day immediately following the effective date of the Spin-Off; 
 CR’ = the Conversion Rate in effect immediately after the close of business on the 10th Trading Day immediately following the effective date of the Spin-Off; 
 FMV0
= the average of the Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to holders of Common Stock applicable to one share of Common Stock over the first 10 consecutive VWAP Trading Day period immediately
following, and including, the effective date of the Spin-Off; and 
 MP0 = the average of the Daily VWAP of Common Stock over the first 10 consecutive VWAP Trading Day period immediately following, and including, the effective date
of the Spin-Off. 
 Such adjustment to the Conversion Rate under this subsection (c) shall occur on the 10th Trading Day from,
and including, the effective date of the Spin-Off; provided that for any conversion within the 10 Trading Days immediately following, and including, the effective date of any Spin-Off, the Conversion Rate shall be adjusted based on the number
of Trading Days between the effective date of such Spin-Off and the Conversion Date. 
 Rights or warrants distributed by the Company to all
holders of Common Stock, entitling the holders thereof to subscribe for or purchase shares of the Company’s Capital Stock, including Common Stock (either initially or under certain circumstances), which rights or warrants, until the occurrence
of a specified event or events (“Trigger Event”): (i) are deemed to be transferred with such shares of Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of Common Stock,
shall be deemed not to have been distributed for purposes of this Section 12.04 (and no adjustment to the Conversion Rate under this Section 12.04 shall be required) until the occurrence of the earliest Trigger Event, whereupon such rights
and warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion Rate shall be made under this subsection (c). If any such rights or warrants are subject to events, upon the occurrence of
which such rights or warrants become exercisable to purchase different securities, evidences of Indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and record date
with respect to new rights or warrants with such rights (and a termination or expiration of the existing rights or warrants without exercise by any of the holders thereof). In 

  

 79 

 
addition, in the event of any distribution (or deemed distribution) of rights or warrants, or any Trigger Event or other event (of the type described in the
preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Rate under this Section 12.04 was made, (1) in the case of any such rights or warrants
that shall all have been redeemed or repurchased without exercise by any holders thereof, the Conversion Rate shall be readjusted upon such final redemption or repurchase to give effect to such distribution or Trigger Event, as the case may be, as
though it were a cash distribution, equal to the per share redemption or repurchase price received by a holder or holders of Common Stock with respect to such rights or warrants (assuming such holder had retained such rights or warrants), made to
all holders of Common Stock as of the date of such redemption or repurchase, and (2) in the case of such rights or warrants that shall have expired or been terminated without exercise by any holders thereof, the Conversion Rate shall be
readjusted as if such rights and warrants had not been issued. 
 For purposes of this subsection (c) and subsections (a) and
(b) of this Section 12.04, any dividend or distribution to which this subsection (c) is applicable that also includes shares of Common Stock to which subsection (a) of this Section 12.04 applies or rights or warrants to
subscribe for or purchase shares of Common Stock to which subsection (a) or (b) of this Section 12.04 applies (or both), shall be deemed instead to be (1) a dividend or distribution of the evidences of Indebtedness, assets or
shares of Capital Stock other than such shares of Common Stock or rights or warrants, to which this subsection (c) applies (and any Conversion Rate adjustment required by this subsection (c) with respect to such dividend or distribution
shall then be made) immediately followed by (2) a dividend or distribution of such shares of Common Stock or such rights or warrants (and any further Conversion Rate adjustment required by subsections (a) and (b) of this
Section 12.04 with respect to such dividend or distribution shall then be made), except (A) the Ex-Date of such dividend or distribution shall under this subsection (c) be substituted as the “Ex-Date” within the meaning of
subsection (a) and subsection (b) and (B) any shares of Common Stock included in such dividend or distribution shall not be deemed “outstanding immediately prior to the Ex-Date for such dividend or distribution or immediately
prior to the effective date of such share split or combination, as the case may be” within the meaning of subsection (a) or “outstanding immediately prior to the Ex-Date for such distribution” within the meaning of subsection
(b). 
 (d) In case the Company shall pay any cash dividends or distributions to all or substantially all holders of its
Common Stock, the Conversion Rate shall be adjusted based on the following formula: 
  

													
		 	 CR’
	 		 	 =
	 	 CR0 ×
	 	 SP0

	  	
		 		 		 		 		 	SP0 - C	  	

  

 80 

 where, 
 CR0 =
the Conversion Rate in effect immediately prior to the close of business on the Ex-Date for such distribution; 
 CR’ = the
Conversion Rate in effect immediately after the close of business on the Ex-Date for such distribution; 
 SP0 = the average of the Daily VWAP of Common Stock for the 10 consecutive VWAP Trading Day period immediately preceding
the Ex-Date for such distribution; and 
 C = the amount in cash per share the Company distributes to holders of Common Stock in such
distribution. 
 Such adjustment shall become effective immediately after the close of
business on the Ex-Date for such dividend or distribution; provided that if the portion of the cash so distributed applicable to one share of the Common Stock is equal to or greater than SP0
 as set forth above, in lieu of the foregoing adjustment, adequate provision shall be made so that each Holder shall receive on the date on which such cash dividend is distributed to holders of Common
Stock, for each $1,000 in principal amount of Notes, the amount of cash such Holder would have received had such Holder owned a number of shares equal to the Conversion Rate on the Ex-Date for such distribution, without being required to convert the
Notes. If such dividend or distribution is not so paid or made, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. 
 For the avoidance of doubt, for purposes of this subsection (d), in the event of any reclassification of the Common Stock, as a result of which the Notes
become convertible into more than one class of Common Stock, if an adjustment to the Conversion Rate is required pursuant to this subsection (d), references in this Section 12.04 to one share of Common Stock or Last Reported Sale Price of one
share of Common Stock shall be deemed to refer to a unit or to the price of a unit consisting of the number of shares of each class of Common Stock into which the Notes are then convertible equal to the numbers of shares of such class issued in
respect of one share of Common Stock in such reclassification. The above provisions of this paragraph shall similarly apply to successive reclassifications. 
 (e) In case the Company or any of its Subsidiaries make a payment in respect of a tender offer or exchange offer for all or any portion of
the Common Stock, to the extent that the cash and value of any other consideration included in the payment per share of Common Stock exceeds the Daily VWAP of the Common Stock on the VWAP Trading Day next succeeding the last date on which tenders or
exchanges may be made pursuant to such tender or exchange offer, the Conversion Rate shall be increased based on the following formula: 
  

 81 

													
		 	 CR’
	 		 	 =
	 	 CR0 ×
	 	 AC + (SP’ × OS’)
	  	
		 		 		 		 		 	OS0 × SP’	  	

 where, 
 CR0 =
the Conversion Rate in effect on the date such tender or exchange offer expires; 
 CR’ = the Conversion Rate in effect on the day
next succeeding the date such tender or exchange offer expires; 
 AC = the aggregate value of all cash and any other consideration as
determined by the Board of Directors or a committee thereof paid or payable for shares purchased in such tender or exchange offer; 
 OS0 =
the number of shares of Common Stock outstanding immediately prior to the date such tender or exchange offer expires; 
 OS’ = the
number of shares of Common Stock outstanding immediately after the date such tender or exchange offer expires (after giving effect to such tender offer or exchange offer); and 
 SP’ = the Last Reported Sale Price of Common Stock on the Trading Day next succeeding the date such tender or exchange offer expires. 
 Such adjustment shall become effective immediately after close of business on the Trading Day next succeeding the date such tender or exchange offer
expires. If the Company or its Subsidiary is obligated to purchase shares of Common Stock pursuant to any such tender or exchange offer, but the Company or its Subsidiary is permanently prevented by applicable law from effecting all or any such
purchases or all or any portion of such purchases are rescinded, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such tender or exchange offer had not been made or had only been made in respect
of the purchases that had been effected. 
 If the application of any of the foregoing formulas (other than in respect of a share
combination) would result in a decrease in the Conversion Rate, no adjustment to the Conversion Rate will be made. 
 For purposes of this
Section 12.04 the term “record date” shall mean, with respect to any dividend, distribution or other transaction or event in which the holders of Common Stock have the right to receive any cash, securities or other property or
in which the Common Stock (or other applicable security) is exchanged for or converted into any combination of cash, securities or other property, the date fixed for determination of shareholders entitled to receive such 

  

 82 

 
cash, securities or other property (whether such date is fixed by the Board of Directors or by statute, contract or otherwise). 
 (f) In addition to those required by subsections (a), (b), (c), (d) and (e) of this Section 12.04, and to the extent
permitted by applicable law and the rules of the NASDAQ Global Select Market or any other securities exchange on which the Common Stock is then listed, the Company from time to time may increase the Conversion Rate by any amount for a period of at
least 20 Business Days if the Board of Directors determines that such increase would be in the Company’s best interest. If the Company makes such determination, it will be conclusive and the Company will notify the Holders of the Notes and the
Trustee of the increased Conversion Rate and the period during which it will be in effect at least 15 calendar days prior to the date the increased Conversion Rate takes effect, in accordance with applicable law. The Company may also, but is not
required to, increase the Conversion Rate to avoid or diminish any income tax to holders of Common Stock or rights to purchase Common Stock in connection with a dividend or distribution of shares or rights to acquire shares or similar event.

 If the Company has in effect a rights plan upon a conversion of the Notes into Common Stock and the rights have not separated from the
Common Stock, Holders will receive, upon a conversion of the Notes in respect of which the Company is required to deliver shares of Common Stock, in addition to such shares of Common Stock, rights under the Company’s rights plan. If prior to
any conversion, the rights have separated from the Common Stock, the Conversion Rate will be adjusted at the time of separation as if the Company had distributed to all holders of Common Stock, capital stock, evidences of indebtedness or other
assets or property pursuant to Section 12.02(d) hereof, subject to readjustment upon the subsequent expiration, termination or redemption of such rights. If the Company’s rights plan existing at the date of this Supplemental Indenture is
terminated, no adjustment in the Conversion Rate will be required upon issuance of rights under any replacement plan. 
 (g)
Except as described in this Section 12.04 or in Section 12.01(e), the Company will not adjust the Conversion Rate. Without limiting the foregoing, no adjustment to the Conversion Rate need be made: 
 (i) upon the issuance of any shares of Common Stock pursuant to any present or future plan providing for the reinvestment of dividends or
interest payable on securities of the Company and the investment of additional optional amounts in shares of Common Stock under any plan; 
 (ii) upon the issuance of any shares of Common Stock or options or rights to purchase or acquire those shares of Common Stock pursuant to any present or future employee, director or consultant benefit plan or program
of or assumed by the Company or any of its Subsidiaries; 
  

 83 

 (iii) upon the issuance of any shares of Common Stock pursuant to any option, warrant,
right or exercisable, exchangeable or convertible security not described in clause (ii) above and outstanding as of the date of this Supplemental Indenture; 
 (iv) for a change in the par value of the Common Stock; 
 (v) for accrued and unpaid Interest; 
 (vi) for accreted principal in excess of the $1,000 Original Principal Amount of the Notes; or 
 (vii) as a result of a tender offer solely to holders of fewer than 100 shares of the Common Stock. 
 (h) All
calculations and other determinations under this Article 12 shall be made by the Company and shall be made to the nearest cent or to the nearest one-ten thousandth (1/10,000) of a share, as the case may be. No adjustment shall be made to the
Conversion Rate unless such adjustment would require a change of at least 1% in the Conversion Rate then in effect at such time. The Company shall carry forward any adjustments that are less than 1% of the Conversion Rate and make such carried
forward adjustments, regardless of whether the aggregate adjustment is less than 1%, to any Notes that are converted upon such conversion. 
 (i) In any case in which this Section 12.04 provides that an adjustment shall become effective immediately after (1) the Ex-Date for an event or (2) the last date on which tenders or exchanges may be
made pursuant to any tender or exchange offer pursuant to subsection (e) of this Section 12.04 (each an “Adjustment Determination Date”), the Company may elect to defer until the occurrence of the applicable Adjustment
Event (as hereinafter defined) (x) issuing to the Holder of any Note converted after such Adjustment Determination Date and before the occurrence of such Adjustment Event, the additional cash and, if applicable, shares of Common Stock or other
securities issuable upon such conversion by reason of the adjustment required by such Adjustment Event over and above the amounts deliverable upon such conversion before giving effect to such adjustment and (y) paying to such Holder any amount
in cash in lieu of any fraction pursuant to Section 12.03. For purposes of this subsection (i), the term “Adjustment Event” shall mean: 
 (i) in any case referred to in clause (1) hereof, the date any dividend or distribution of Common Stock, shares of Capital Stock,
evidences of Indebtedness, other assets or property or cash is paid or made, the effective date of any share split or combination or the date of expiration of any rights or warrants, and 
  

 84 

 (ii) in any case referred to in clause (2) hereof, the date a sale or exchange of
Common Stock pursuant to such tender or exchange offer is consummated and becomes irrevocable. 
 (j) For purposes of this
Section 12.04, the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of
Common Stock. 
 (k) For the avoidance of doubt, if a Holder converts Notes prior to the effective date of a Fundamental
Change, and the Fundamental Change does not occur, the Holder shall not be entitled to Additional Shares in connection with such conversion. 
 (l) With respect to a conversion of Notes pursuant to this Article 12, on the date the Shares issuable upon conversion of the Notes are delivered to the converting Holder pursuant to Section 12.02(a) (the
“Delivery Date”), the Person in whose name any certificate representing any shares of Common Stock issuable upon such conversion is registered shall be treated as a stockholder of record of the Company on such Delivery Date. On and
after the Delivery Date with respect to a conversion of Notes pursuant hereto, all rights of the Holders of such Notes shall terminate. A Holder of a Note is not entitled, as such, to any rights of a holder of Common Stock unless and until such
Holder converts such Note and receives shares of Common Stock in respect of such conversion on the Delivery Date with respect to such conversion. 
 (m) Whenever any provision of this Article 12 requires a calculation of Last Reported Sale Prices over a span of multiple days, the Company shall make appropriate adjustments to account for any adjustment to the
Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the Ex-Date of the event occurs, at any time during the period from which such calculation is to be calculated; provided that such
adjustments shall only be made to the Conversion Rate relating to days prior to the date that the adjustment to the Conversion Rate becomes effective. 
 (n) If the effective date of any adjustment event described in this Section 12.04 occurs during an Observation Period for any Notes, the Company shall make proportional adjustments to the number of Deliverable
Shares (in the same manner as the Conversion Rate) for each VWAP Trading Day during the portion of the Observation Period preceding the effective date of such adjustment event. 
 SECTION 12.05 Notice of Adjustments of Conversion Rate. 
 Whenever the Conversion Rate is adjusted as herein provided: 
  

 85 

 (a) the Company shall compute the adjusted Conversion Rate 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 showing in reasonable detail the facts upon which such adjustment is based, and such certificate
shall promptly be filed with the Trustee and with each Conversion Agent (if other than the Trustee); and 
 (b) upon each such
adjustment, a notice stating that the Conversion Rate has been adjusted and setting forth the adjusted Conversion Rate shall be required, such notice shall be provided by the Company to all Holders in accordance with Section 1.6 of the Base
Indenture. 
 Neither the Trustee nor any Conversion Agent shall be under any duty or responsibility with respect to any such certificate or
the information and calculations contained therein, except to exhibit the same to any Holder desiring inspection thereof at its office during normal business hours or in such other manner of inspection as the Trustee deems practicable. 

SECTION 12.06 Company to Reserve Common Stock. 
 The Company shall at all times reserve and keep available, free from preemptive rights, out of its authorized but unissued Common Stock, for the purpose
of effecting the conversion of Notes, the full number of shares of Common Stock then issuable upon the conversion of all Outstanding Notes. 
 SECTION 12.07 Taxes on Conversions. 
 Except as provided in the next sentence, the Company
shall pay all documentary, stamp or similar issue or transfer tax due that may be payable in respect of the issue or delivery of shares of Common Stock on conversion of Notes pursuant hereto. The Company shall not, however, be required, and the
Holder shall instead be required, to pay any tax or duty that may be payable in respect of (i) income of the Holder, or (ii) any transfer involved in the issue and delivery of shares of Common Stock in a name other than that of the Holder
of the Note or Notes 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 duty, or has established to the satisfaction of the Company
that such tax or duty has been paid. 
 SECTION 12.08 Certain Covenants. 
 Before taking any action which would cause an adjustment reducing the Conversion Rate below the then par value, if any, of the shares of Common Stock
issuable upon conversion of the Notes, the Company shall take all corporate action, if any, which it reasonably determines may be necessary in order that the 

  

 86 

 
Company may validly and legally issue shares of such Common Stock at such adjusted Conversion Rate. 
 The Company covenants that all shares of Common Stock issued upon conversion of Notes shall be fully paid and non-assessable by the Company and free from
all liens created by the Company. 
 SECTION 12.09 Cancellation of Converted Notes. 
 All Notes delivered for conversion shall be delivered to the Trustee or its agent and canceled by the Trustee as provided in Section 3.11.

 SECTION 12.10 Provision in Case of Effect of Reclassification, Consolidation, Merger or Sale.

 If there shall occur (i) any Fundamental Change described in clause (2) of the definition of Fundamental Change, (ii) any
reclassification or change of the outstanding shares of 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 split, subdivision or combination), (iii) any
consolidation, binding share exchange, recapitalization, reclassification, merger, combination or other similar event, or (iv) any sale or conveyance of all or substantially all of the property and assets of the Company to any other Person, in
any case as a result of which holders of Common Stock shall be entitled to receive cash, securities or other property or assets with respect to or in exchange for their shares of Common Stock (any such event described in clauses (i) through
(iv) a “Merger Event”), then: 
 (a) the Company or the successor or purchasing Person, as the case may
be, shall execute with the Trustee (subject to the Trustee’s rights as provided herein) a supplemental indenture (which shall comply with the Trust Indenture Act as in force at the date of execution of such supplemental indenture if such
supplemental indenture is then required to so comply) permitted under Section 8.01(f) providing for the conversion and settlement of the Notes as set forth in this Supplemental Indenture. Such supplemental indenture shall provide for
adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article 12 and the Trustee may conclusively rely on the determination by the Company of the equivalency of such adjustments. If, in the
case of any Merger Event, the Reference Property includes shares of stock or other securities and assets of a company other than the successor or purchasing company, as the case may be, in such change of control, consolidation, binding share
exchange, recapitalization, reclassification, merger, combination, sale or conveyance or Fundamental Change described in clause (2) of the definition of Fundamental Change, then such supplemental indenture shall also be executed by such other
company and shall contain such additional provisions to protect the interests of the Holders of the Notes as the Board of Directors shall reasonably consider 

  

 87 

 
necessary by reason of the foregoing, including to the extent required by the Board of Directors and practicable the provisions providing for the repurchase
rights set forth in Article 11. 
 In the event a supplemental indenture is executed pursuant to this Section 12.10, the Company shall
promptly file with the Trustee an Officers’ Certificate (and the documents and information provided for in Section 9.3 of the Base Indenture) briefly stating the reasons therefore, the kind or amount of cash, securities, property or assets
that will constitute the Reference Property after any such Merger Event, any adjustment to be made with respect thereto and that all conditions precedent have been complied with, and shall promptly mail notice thereof to all Holders, and the Trustee
shall be protected in relying on such Officers’ Certificate; it being understood that the Trustee shall have no responsibility to determine the correctness of any provisions contained in any supplemental indenture executed pursuant to this
Section 12.10. 
 If any securities to be provided for the purpose of conversion of Notes hereunder require registration with or
approval of any governmental authority under any federal or state law before such securities may be validly issued upon conversion, each supplemental indenture executed pursuant to this Section 12.10 shall provide that the Company or the
successor or the purchasing Person, as the case may be, or if the Reference Property includes shares of stock or other securities and assets of a company other than the successor or purchasing company, as the case may be, then such company, shall
use all commercially reasonable efforts, to the extent then permitted by the rules and interpretations of the Commission (or any successor thereto), to secure such registration or approval in connection with the conversion of Notes. 
 Notwithstanding the provisions of Section 12.02 and Section 12.03, and subject to the provisions of Section 12.01, at the effective time
of such Merger Event, the right to convert each $1,000 in principal amount of Notes shall be changed to a right to convert such Notes by reference to the kind and amount of cash, securities, or other property that a holder of a number of shares of
Common Stock equal to the Conversion Rate immediately prior to such transaction would have owned or been entitled to receive (the “Reference Property”) such that from and after the effective time of such transaction, a Holder shall
be entitled thereafter to convert its Notes into the same type (and in the same proportion) of Reference Property, subject to the Company’s right to elect to settle conversions, in whole or in part, in shares of Common Stock, cash or a
combination of cash and shares of Common Stock, provided that if the Company makes the Net Share Settlement Election, upon conversion, Holders will receive Reference Property as follows: (x) either (i) all cash or (ii) cash up
to the Specified Dollar Amount, and (y) in lieu of the shares of Common Stock otherwise deliverable, Reference Property. The amount of consideration, and, consequently, Reference Property, Holders receive upon conversion will be based on the
Daily Conversion Values of Reference Property and the applicable Conversion Rate, as described in Section 

  

 88 

 
12.02. For purposes of determining the constitution of Reference Property, the type and amount of consideration that a holder of Common Stock would have been
entitled to in the case of any Merger Event that causes the Common Stock to be converted into the right to receive more than a single type of consideration determined, based in part upon any form of stockholder election, such consideration will be
deemed to be the weighted average of the types and amounts of consideration received by the holders of Common Stock that affirmatively make such an election, or (ii) if no holders of Common Stock affirmatively make such an election, the types
and amount of consideration actually received by such holders. The Company shall not become a party to any such transaction unless its terms are consistent with the preceding. None of the foregoing provisions shall affect the right of a Holder to
convert its Notes in accordance with the provisions of this Article 12 prior to the effective date. 
 (b) The Company shall
cause notice of the execution of such supplemental indenture to be mailed to each Holder, at his address appearing on the Securities Register provided for in this Supplemental Indenture, within 20 calendar days after execution thereof. Failure to
deliver such notice shall not affect the legality or validity of such supplemental indenture. 
 (c) The above provisions of
this Section 12.10 shall similarly apply to successive Merger Events. 
 SECTION 12.11 Company
Responsible for Making Calculations. 
 Except as otherwise provided herein, the Company will be responsible for making all calculations
required under the Notes and this Supplemental Indenture. The Company will make these calculations in good faith and absent manifest error, these calculations will be final and binding on the Holders. The Company will provide a schedule of such
calculations to each of the Trustee and the Conversion Agent, and each of the Trustee and the Conversion Agent is entitled to conclusively rely upon the accuracy of such calculations without independent verification. The Trustee will forward the
Company’s calculations to any Holder upon the written request of such Holder. 
 SECTION 12.12
Responsibility of Trustee for Conversion Provisions. 
 The Trustee and any Conversion Agent shall not at any time be under any
duty or responsibility to any Holder to determine whether any facts exist which may require any adjustment of the Conversion Rate, or with respect to the nature or extent of any such adjustment when made, or with respect to the method employed,
herein or in any supplemental indenture provided to be employed, in making the same, or whether a supplemental indenture need be entered into. Neither the Trustee nor any Conversion Agent shall be accountable with respect to the validity or value
(or the kind or amount) of any Common Stock, or of any other securities or property or cash, which may at any time be issued or delivered 

  

 89 

 
upon the conversion of any Notes; and it or they do not make any representation with respect thereto. Neither the Trustee nor any Conversion Agent shall be
responsible for any failure of the Company to make or calculate any cash payment or to issue, transfer or deliver any shares of Common Stock or share certificates or other securities or property or cash upon the surrender of any Note for the purpose
of conversion; and the Trustee and any Conversion Agent shall not be responsible for any failure of the Company to comply with any of the covenants of the Company contained in this Article 12. 
 This instrument may be executed in any number of counterparts, each of which so executed shall be deemed to be an original, but all such counterparts
shall together constitute but one and the same instrument.
