 (b) The fact and date of the execution by any Person of any such instrument or writing may
be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to
him the execution thereof. Where such execution is by a signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient proof of his authority. The fact and date of the execution of any
such instrument or writing, or the authority of the Person executing the same, may also be proved in any other reasonable manner which the Trustee deems sufficient. 
 (c) The ownership of Registered Securities shall be proved by the Security Register or by a certificate of the Security Registrar. 
 (d) The ownership of Bearer Securities may be proved by the production of such Bearer Securities or by a certificate executed, as depository, by any trust company, bank, banker or other depository,
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 depository, or exhibited to it, the Bearer Securities therein described; or
such facts 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 and 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 ownership of Bearer Securities may also be proved in any other manner which the Trustee deems
sufficient. 
 (e) 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 316(c), such record date shall be the record date specified in or pursuant to such Board Resolution, which shall be a date not
earlier than the date 30 days prior to the first solicitation of Holders generally in connection therewith and not later than the date such solicitation is completed. If such a record date is fixed, such request, demand, authorization, direction,
notice, consent, waiver or other Act may be 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. 
 (f) 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. 

(g) The Trustee may, in its sole discretion, set any day as a record date for the purpose of determining the Holders of Outstanding
Securities of any series entitled to join in the giving or 

  
 13 

 
making of (i) any Notice of Default, (ii) any declaration of acceleration referred to in Section 502, (iii) any request to institute proceedings referred to in
Section 507(2) or (iv) any direction referred to in Section 512, in each case with respect to Securities of such series. If any record date is set pursuant to this paragraph, the Holders of Outstanding Securities of such series on
such record date, and no other Holders, shall be entitled to join in such notice, declaration, request or direction, whether or not such Holders remain Holders after such record date, provided that no such action shall be effective hereunder unless
taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of Outstanding Securities of such series on such record date. Nothing in this paragraph shall be construed to prevent the Trustee from setting a new
record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be cancelled and of no effect), and nothing in this
paragraph shall be construed to render ineffective any action taken by Holders of the requisite principal amount of Outstanding Securities of the relevant series on the date such action is taken. Promptly after any record date is set pursuant to
this paragraph, the Trustee, at the Company’s expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Company in writing and to each Holder of Securities of the
relevant series in the manner set forth in Section 106. 
 (h) With respect to any record date set pursuant to this
Section, the party hereto which sets such record dates may designate any day as the “Expiration Date” and from time to time may change the Expiration Date to any earlier or later day; provided that no such change shall be effective unless
notice of the proposed new Expiration Date is given to the other party hereto in writing, and to each Holder of Securities of the relevant series in the manner set forth in Section 106, on or prior to the existing Expiration Date. If an
Expiration Date is not designated with respect to any record date set pursuant to this Section, the party hereto which set such record date shall be deemed to have initially designated the 180/th/ day after such record date as the Expiration Date
with respect thereto, subject to its right to change the Expiration Date as provided in this paragraph. Notwithstanding the foregoing, no Expiration Date shall be later than the 180/th/ day after the applicable record date. 

Without limiting the foregoing, a Holder entitled hereunder to take any action hereunder with regard to any particular Security may do so
with regard to all or any part of the principal amount of such Security or by one or more duly appointed agents each of which may do so pursuant to such appointment with regard to all or any part of such principal amount. 

 

	SECTION 105.	Notices, etc., to the Trustee and Company. 

 Any request, demand, authorization, direction, notice, consent, waiver or Act of Holders or other document provided or permitted by this Indenture to be made upon, given or furnished to or filed with,

 (1) the Trustee by any Holder or by the Company shall be sufficient for every purpose hereunder if made, given, furnished or
filed in writing to or with the Trustee at its Corporate Trust Office, Attention: Corporate Trustee 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, to the Company addressed to it at the address of its
principal office specified in the first paragraph of this Indenture or at any other address previously furnished in writing to the Trustee by the Company. 

  
 14 

	SECTION 106.	Notice to Holders; Waiver. 

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 (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to each such Holder affected by such event, at his address as it appears in the Security Register, not later than the latest
date, and not earlier than the earliest date, prescribed for the giving of such notice. 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 herein. Any notice mailed to a Holder in
the manner herein prescribed shall be conclusively deemed to have been received by such Holder, whether or not such Holder actually receives such notice. 
 If by reason of the suspension of or irregularities in regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such notification to Holders of
Registered Securities as shall be made with the approval of the Trustee shall constitute a sufficient notification to such Holders for every purpose hereunder. 
 Except as otherwise expressly provided herein or otherwise specified with respect to any Securities pursuant to Section 301, where this Indenture provides for notice to Holders of Bearer Securities
of any event, such notice shall be sufficiently given 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, and if the Securities of such series are listed on any
stock exchange outside the United States, in any place at which such Securities are listed on a securities exchange to the extent that such securities exchange so requires, on a Business Day, such publication to be not later than the latest date,
and not earlier than the earliest 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 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 any particular Holder 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. 
  

	SECTION 107.	Effect of Headings and Table of Contents. 

 The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof.

	SECTION 108.	Successors and Assigns. 

All covenants and agreements in this Indenture by the Company shall bind its successors and assigns, whether so expressed or not.

  

	SECTION 109.	Separability Clause. 

 In
case any provision in this Indenture or in any Security or coupon shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. 

 

	SECTION 110.	Benefits of Indenture. 

Nothing in this Indenture or in the Securities or coupons appertaining thereto, express or implied, shall give to any Person, other than
the parties hereto, any Security Registrar, any Paying Agent, any Authenticating Agent and their successors hereunder, the holders of Senior Debt and the Holders and, to the extent expressly provided in any Trust Agreement, the Holders of Preferred
Securities, any benefit or any legal or equitable right, remedy or claim under this Indenture. 
  

	SECTION 111.	No Personal Liability. 

No recourse under or upon any obligation, covenant or agreement contained in this Indenture, in any Security or coupon appertaining
thereto, or because of any indebtedness evidenced thereby, shall be had against any promoter, as such, or against any past, present or future shareholder, officer or director, as such, of the Company or of any successor, either directly or through
the Company or any successor, under any rule of law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise, all such liability being expressly waived and released by the
acceptance of the Securities by the Holders thereof and as part of the consideration for the issue of the Securities. 
  

	SECTION 112.	Governing Law; Waiver of Trial by Jury. 

 This Indenture and the Securities and coupons shall be governed by and construed in accordance with the laws of the State of New York. This Indenture is subject to the provisions of the TIA that are
required to be part of this Indenture and shall, to the extent applicable, be governed by such provisions and any provisions of this Indenture that are not permitted by the provisions of the TIA shall be deemed to be deleted or modified to the
extent such provisions are required to be deleted or modified for the Indenture to be qualified under the TIA. Each of the Company and the Trustee irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by
jury in any legal proceeding arising out of or relating to this Indenture or the transactions contemplated hereby. 
  

	SECTION 113.	Legal Holidays. 

 In any
case where any Interest Payment Date, Redemption Date, Repayment Date, sinking fund payment date, Stated Maturity or Maturity of any Security or the last date on which a Holder has the right to convert or exchange a Security at a particular
conversion or exchange price shall not be a Business Day at any Place of Payment, then (notwithstanding any other provision of this Indenture or any Security or coupon other than a provision in the Securities of any series which specifically states
that such provision shall apply in lieu hereof), payment of interest or any Additional Amounts or principal (and premium or Make-Whole Amount, if any) need not be made at such Place of Payment on such date, conversion or exchange need not be made at
such Place of Payment on such date, but may be made on the next 

  
 16 

 
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 or sinking fund payment date, or at the
Stated Maturity or Maturity or on such last day for conversion or exchange, provided that so long as such payment is made on the next succeeding Business Day, 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 or on such last day for conversion or exchange, as the case may be, to such Business Day.

Resolutions, shall have such appropriate insertions, omissions, substitutions and other variations as are required or permitted by this Indenture or any indenture supplemental hereto, and may have such letters, numbers or other marks of
identification or designation and such legends or endorsements placed thereon as the Company may deem appropriate and as are not inconsistent with the provisions of this Indenture, or as may be required to comply with any law or with any rule or
regulation made pursuant thereto or with any rule or regulation of any stock exchange on which the Securities may be listed or Depository therefor, or to conform to usage. If temporary Securities of any series are issued as permitted by
Section 304, the form thereof also shall be established as provided by the preceding sentence. If the forms of Securities and coupons, if any, of any series are established by, or by action taken pursuant to, a Board Resolution, a copy of the
Board Resolution together with an appropriate record of any such action taken pursuant thereto, including a copy of the approved form of Securities or coupons, if any, shall be certified by the Secretary or an Assistant Secretary of the Company and

 Unless otherwise specified as contemplated by Section 301, Bearer Securities shall have interest coupons attached. 
 The definitive Securities and coupons shall be printed, lithographed or engraved or produced by any combination of these methods on a steel engraved border or steel engraved borders or may be produced in
any other manner, all as determined by the officers of the Company executing such Securities or coupons, as evidenced by their execution of such Securities or coupons. 
 Securities distributed to holders of book-entry Preferred Securities shall be distributed in the form of one or more global securities registered in the name of a Depositary or its nominee, and deposited
with the Security Registrar, as custodian for such Depositary, or held by such Depositary, for credit by the Depositary to the respective accounts of the beneficial owners of the Securities represented thereby (or such other accounts as they may

	SECTION 203.	Securities Issuable in Global Form. 

 If Securities of or within a series are issuable in global form, as specified as contemplated by Section 301, then, notwithstanding clause (8) of Section 301 and the provisions of
Section 302, 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 written instruction 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 303 or 304. Subject to the provisions of Section 303 and, if applicable, Section 304, the Trustee shall deliver and redeliver any Security in permanent global form in the manner

respect to endorsement or delivery or redelivery of a Security in global form shall be in writing but need not comply with Section 102 and need not be accompanied by an Opinion of Counsel. 

The provisions of the last sentence of Section 303 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 102 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 303.

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.

 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 coupon 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 the 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 301 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 to Euroclear or Clearstream, as the case may be, in the form set forth in Exhibit A-1 to this Indenture or such other certificate as may be specified with respect to any series of Securities
pursuant to Section 301, 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. Except as permitted by Section 306, the Trustee shall not authenticate and deliver any Bearer Security unless all appurtenant coupons for interest then matured have been detached and
canceled. 
 If all of the Securities are not to be issued at one time and if the 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 the terms of particular Securities of such series, such as interest rate or formula,
maturity date, date of issuance and date from which interest shall accrue. In authenticating Securities, and accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee shall be entitled to receive, and
(subject to Section 612 and TIA Section 315(a) through 315(d)) shall be fully protected in conclusively relying upon: 

(i) an Opinion of Counsel complying with Section 102 and stating that: 

(a) the form or forms of such Securities and any coupons have been, or will have been upon compliance with such procedures as may be
specified therein, established in conformity with the provisions of this Indenture; 
 (b) the terms of such Securities and any
coupons have been, or will have been upon compliance with such procedures as may be specified therein, established in conformity with the provisions of this Indenture; and 
 (c) such Securities, together with any coupons appertaining thereto, when completed pursuant to such procedures as may be specified therein, and executed and delivered by the Company to the Trustee for
authentication in accordance with this Indenture, 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
constitute legal, valid and binding obligations of the Company, enforceable in accordance with their terms, subject to applicable bankruptcy, insolvency, reorganization and other similar laws of general applicability relating to or affecting the
enforcement of creditors’ rights generally and to general equitable principles and to such other matters as may be specified therein; and 
 (ii) an Officers’ Certificate complying with Section 102 and stating that all conditions precedent provided for in this Indenture relating to the issuance of such Securities have been, or will
have been upon compliance with such procedures as may be specified therein, complied with and that, to the best of the knowledge of the signers of such certificate, no Event of Default with respect to such Securities shall have occurred and be
continuing. 

  
 23 

 Notwithstanding the provisions of Section 301 and of the preceding paragraph, if all
the Securities of any series are not to be issued at one time, it shall not be necessary to deliver a Company Order, an Opinion of Counsel or an Officers’ Certificate otherwise required pursuant to the preceding paragraph at the time of
issuance of each Security of such series, but such order, opinion and certificate, with appropriate modifications to cover such future issuances, shall be delivered at or before the time of issuance of the first Security of such series. 

The Trustee shall not be required to authenticate such Securities if the issue of such Securities pursuant to this Indenture will affect
the Trustee’s own rights, duties, obligations 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 301. 
 No Security or coupon appertaining thereto shall be entitled to any benefit under this
Indenture or be valid or obligatory for any purpose unless there appears on such Security or the Security to which such coupon appertains a certificate of authentication substantially in the form provided for herein duly executed by the Trustee by
manual signature of an authorized signatory, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder 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 309 together with a written statement (which need not comply with Section 102 and need not be accompanied by an Opinion of Counsel) stating that such Security has never been issued or 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 304.	Temporary Securities. 

(a) 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, 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 the officers of the Company executing such Securities
may determine, as conclusively evidenced by their execution of such Securities. In the case of Securities of any series, 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 Section 304(b) or as otherwise provided in or pursuant to a Board Resolution), 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 non-matured coupons appertaining thereto), the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a like principal amount
of definitive Securities of the same series of authorized denominations; provided, 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 3.03. 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. 

  
 24 

 (b) Unless otherwise provided as contemplated in Section 301, this Section 304(b)
shall govern the exchange of temporary Securities issued in global form other than through the facilities of DTC. If any such temporary Security is issued in global form, then such temporary global Security shall, unless otherwise provided therein,
be delivered to the London office of a depository or common depository (the “Common Depository”), for the benefit of Euroclear and Clearstream. 
 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 an 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 Depository 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 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 or within 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 301, 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 Depository, 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, if any, 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, if any, held for its account then to be exchanged, each in the form set forth
in Exhibit A-2 to this Indenture or in such other form as may be established pursuant to Section 301; 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 303. 
 Unless otherwise specified in such temporary global Security, the
interest of a beneficial owner of Securities of a series in a temporary global Security shall be exchanged for definitive Securities of the same series and of like tenor following the Exchange Date when the account holder instructs Euroclear or
Clearstream, as the case may be, to request such exchange on his behalf and delivers to Euroclear or Clearstream, as the case may be, a certificate in the form set forth in Exhibit A-1 to this Indenture (or in such other form as may be established
pursuant to Section 301), dated no earlier than 15 days prior to the Exchange Date, copies of which certificate shall be available from the offices of Euroclear or Clearstream, the Trustee, any Authenticating Agent appointed for such series of
Securities and each Paying Agent. Unless otherwise specified in such temporary global Security, any such exchange shall be made free of charge to the beneficial owners of such temporary global Security, except that a Person receiving definitive
Securities must bear the cost of insurance, postage, transportation and the like unless such Person takes delivery of such definitive Securities in person at the offices of Euroclear or Clearstream. 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 301, interest payable on a temporary global Security on an Interest Payment 

  
 25 

 
Date for Securities of such series occurring prior to the applicable Exchange Date shall be payable to Euroclear or Clearstream on such Interest Payment Date upon delivery by Euroclear or
Clearstream to the Trustee of a certificate or certificates in the form set forth in Exhibit A-2 to this Indenture (or in such other forms as may be established pursuant to Section 301), for credit without further interest on or after such
Interest Payment Date to the respective accounts of 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 in the form set forth as Exhibit A-1 to this Indenture (or in such other forms as may be established pursuant to Section 301).
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 304(b) and of the third paragraph of
Section 303 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 interest
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 or Clearstream and not paid as herein provided shall be returned to the Trustee prior to the expiration of two years after such Interest Payment Date in order to be repaid to the Company. 

 

	SECTION 305.	Registration, Registration of Transfer and Exchange. 

 The Company shall cause to be kept at the Corporate Trust Office of the Trustee or in any office or agency of the Company in a Place of Payment a register for each series of Securities (the registers
maintained in such office or in any such office or agency of the Company in a Place of Payment being herein sometimes referred to collectively as the “Security Register”) in which, subject to such reasonable regulations as it or the
Security Registrar may prescribe, the Company shall provide for the registration of Registered Securities and of transfers of Registered Securities. The Security Register shall be in written form or any other form capable of being converted into
written form within a reasonable time. The Trustee, at its Corporate Trust Office, is hereby initially appointed “Security Registrar” for the purpose of registering Registered Securities and transfers of Registered Securities on such
Security Register as herein provided. In the event that the Trustee shall cease to be Security Registrar, it shall have the right to examine the Security Register at all reasonable times and to require that a copy of the Security Register in written
form be delivered to it from time to time as reasonably requested. Subject to the provisions of this Section 305, upon surrender for registration of transfer of any Registered Security of any series at any office or agency of the Company in a
Place of Payment for that series, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Registered Securities of the same series, of any authorized
denominations and of a like aggregate principal amount, bearing a number not contemporaneously outstanding, and containing identical terms and provisions. 
 Subject to the provisions of this Section 305, at the option of the Holder, Registered Securities of any series (not in global form) may be exchanged for other Registered Securities of the same
series, of any authorized denomination or denominations and of a like aggregate principal amount, containing identical terms and provisions, upon surrender of the Registered Securities to be exchanged at any such office or agency. Whenever any such
Registered Securities are so surrendered for exchange, the Company shall execute, and 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 301, Bearer Securities may not be issued in exchange for Registered Securities. 

  
 26 

 If (but only if) permitted as contemplated by Section 301, at the option of the Holder,
Bearer Securities of any series may be exchanged for Registered Securities of the same series of any authorized denominations 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 1002, 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. Whenever any Securities are so surrendered for
exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Securities which the holder making the exchange is entitled to receive. 
 Notwithstanding the foregoing, except as otherwise specified as contemplated by Section 301, any permanent global Security shall be exchangeable only as provided in this paragraph. If the depository
for any permanent global Security is DTC, then, unless the terms of such global Security expressly permit such global Security to be exchanged in whole or in part for definitive Securities, a global Security may be transferred, in whole but not in
part, only to a nominee of DTC, or by a nominee of DTC to DTC, or to a successor to DTC for such global Security selected or approved by the Company or to a nominee of such successor to DTC. If at any time DTC notifies the Company that it is
unwilling or unable to continue as depository for the applicable global Security or Securities or if at any time DTC ceases to be a clearing agency registered under the Exchange Act if so required by applicable law or regulation, the Company shall
appoint a successor depository with respect to such global Security or Securities. If (x) a successor depository for such global Security or Securities is not appointed by the Company within 90 days after the Company receives such notice or
becomes aware of such unwillingness, inability or ineligibility, (y) an Event of Default has occurred and is continuing and the beneficial owners representing a majority in principal amount of the applicable series of Securities represented by
such global Security or Securities advise DTC to cease acting as depository for such global Security or Securities or (z) the Company, in its sole discretion and subject to the procedures of DTC, determines at any time that all Outstanding
Securities (but not less than all) of any series issued or issuable in the form of one or more global Securities shall no longer be represented by such global Security or Securities (provided, however, the Company may not make such determination
during the 40-day restricted period provided by Regulation S under the Securities Act or during any other similar period during which the Securities must be held in global form as may be required by the Securities Act), then the Company shall
execute, and the Trustee shall authenticate and deliver definitive Securities of like series, rank, tenor and terms in definitive form in an aggregate principal amount equal to the principal amount of such global

  
 27 

 
Security or Securities. If any beneficial owner of an interest in a permanent global Security is otherwise entitled to exchange such an 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 301 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 execute, and the Trustee shall authenticate and deliver definitive Securities in aggregate principal amount equal to the principal
amount of such beneficial owner’s interest in such permanent global Security. On or after the earliest date on which such interests may be so exchanged, such permanent global Security shall be surrendered for exchange by DTC or such other
depository as shall be specified in the Company Order with respect thereto to the Trustee, as the Company’s agent for such purpose; 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. 

Every Registered Security presented or surrendered for registration of transfer or for exchange or redemption shall (if so required by
the Company, the Trustee or the Security Registrar) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to 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 304, 906, 1107 or 1305 not
involving any transfer. 
 The Company or the Trustee, as applicable, shall not be required (i) to issue, register the
transfer of or exchange any Security if such Security may be among those selected for redemption during a period beginning at the opening of business 15 days before selection of the Securities to be redeemed under Section 1103 and ending at the
close of business on (A) if such Securities are issuable only as Registered Securities, the day of the mailing of the relevant notice of redemption and (B) if such Securities are issuable as Bearer Securities, the day of the first
publication of the relevant notice of redemption or, if such Securities 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, in the case of any Registered Security to be redeemed in part, the portion thereof not to be redeemed, or (iii) to exchange any 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

  
 28 

 
redemption, or (iv) to issue or to register the transfer or exchange of 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. 
  

	SECTION 306.	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 or the Company, together with such security or indemnity as may be required by the Company
or the Trustee to save each of them or any agent of either of them harmless, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of the same series and principal amount, containing identical
terms and provisions and bearing a number not contemporaneously outstanding, with coupons corresponding to the coupons, if any, appertaining to the surrendered Security. 
 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 actual 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 its written request 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 principal amount, containing identical terms and provisions 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 Company in its
discretion may, instead of issuing a new Security, with coupons corresponding to coupons, if any, appertaining to such destroyed, lost or stolen Security or to the Security to which such destroyed, lost or stolen coupon appertains, pay such Security
or coupon; provided, however, that payment of principal of (and premium or Make-Whole Amount, if any), any interest on and any Additional Amounts with respect to Bearer Securities shall, except as otherwise provided in Section 1002, be payable
only at an office or agency located outside the United States and, unless otherwise specified as contemplated by Section 301, 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 destroyed, lost or stolen Security, or in exchange for a Security to which a destroyed, lost or
stolen coupon appertains, shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security and its coupons, if any, or the 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. 

  
 29 

	SECTION 307.	Payment of Interest; Interest Rights Preserved. 

 Except as otherwise specified with respect to a series of Securities in accordance with the provisions of Section 301, interest on any Registered Security that is payable, and is punctually paid or
duly provided for, on any Interest Payment Date shall be paid to the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest at the office or
agency of the Company maintained for such purpose pursuant to Section 1002; provided, however, that each installment of interest 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 308, to the address of such Person as it appears on the Security Register or (ii) transfer to an account maintained by the payee located inside the
United States. 
 Unless otherwise provided as contemplated by Section 301 with respect to the Securities of any series,
payment of interest may be made, in the case of a Bearer Security, by transfer to an account maintained by the payee with a bank located outside the United States. 
 Unless otherwise provided as contemplated by Section 301, every permanent global Security will provide that interest, if any, payable on any Interest Payment Date will be paid to DTC, Euroclear
and/or Clearstream, as the case may be, with respect to that portion of such permanent global Security held for its account by DTC, Euroclear or Clearstream, as the case may be, for the purpose of permitting such party to credit the interest
received by it in respect of such permanent global Security to the accounts of the beneficial owners thereof. 
 In case a
Bearer Security of any series is surrendered in exchange for a Registered Security of such series after the close of business (at an office or agency in a Place of Payment for such series) on any Regular Record Date and before the opening of
business (at such office or agency) on the next succeeding Interest Payment Date, such Bearer Security shall be surrendered without the coupon relating to such Interest Payment Date and interest will not be payable on such Interest Payment Date 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. 

Except as otherwise specified with respect to a series of Securities in accordance with the provisions of section 301, any interest on
any Registered Security of any series that is payable, but is not punctually paid or duly provided for, on any Interest Payment Date (herein called “Defaulted Interest”) shall forthwith cease to be payable to the registered Holder thereof
on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in clause (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 (which shall not be less than 20 days after such notice is received by the Trustee), and at the same time
the Company shall deposit with the Trustee an amount of money in the currency or currencies, currency unit or units or composite currency or currencies in which the Securities of such series are payable (except as otherwise specified pursuant to
Section 301 for the Securities of such series) 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

  
 30 

 
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 of Registered Securities of such series at his address as it appears in the Security 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 mailed as aforesaid, such Defaulted Interest shall be paid 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 such Special Record Date and shall no longer be payable pursuant to the following clause (2). In case a Bearer Security of any series is surrendered at the office or
agency in a Place of Payment for such series in exchange for a Registered Security of such series after the close of business at such office or agency on 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 proposed date of payment and Defaulted Interest will not be payable on such proposed date of payment 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. 

(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 written 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 and Section 305, 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. 
 Subject to the provisions of Section 1402 and except as otherwise specified
with respect to a series of Securities in accordance with the provisions of section 301, in the case of any Security which is converted or exchanged after any Regular Record Date and on or prior to the next succeeding Interest Payment Date (other
than any Security, the principal of (or premium, if any, on) which shall become due and payable, whether at a Stated Maturity or by declaration of acceleration, call for redemption, or otherwise, prior to such Interest Payment Date), interest whose
Stated Maturity is on such Interest Payment Date shall be payable on such Interest Payment Date notwithstanding such conversion or exchange, and such interest (whether or not punctually paid or duly provided for) shall be paid to the Person in whose
name that Security (or one or more Predecessor Securities) is registered at the close of business on such Regular Record Date. Except as otherwise expressly provided in the immediately preceding sentence, in the case of any Security which is
converted or exchanged, interest whose Stated Maturity is after the date of conversion or exchange of such Security shall not be payable. 
  

	SECTION 308.	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 owner of such Security for the purpose of receiving payment of principal of (and premium or Make-Whole Amount, if any), and (subject to Sections 305 and
307) interest on and Additional Amounts with respect to, such Registered Security and for all other purposes whatsoever, whether or not such Registered Security be overdue, and neither the Company, the Trustee nor any agent of the Company or the
Trustee shall be affected by notice to the contrary. 

  
 31 

 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 Holder of any Bearer Security and the Holder 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 coupon be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary. 

None of the Company, the Trustee, any Paying Agent or the Security Registrar will have any responsibility or liability for any aspect of
the records relating to or payments made on account of beneficial ownership interests of a Security in global form or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests. 

Notwithstanding the foregoing, with respect to any global Security, nothing herein shall prevent the Company, the Trustee, or any agent
of the Company or the Trustee, from giving effect to any written certification, proxy or other authorization furnished by any depository, as a Holder, with respect to such global Security or impair, as between such depository and owners of
beneficial interests in such global Security, the operation of customary practices governing the exercise of the rights of such depository (or its nominee) as Holder of such global Security. 

 

	SECTION 309.	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 sinking fund payment shall, if surrendered to any Person other than the Trustee, be
delivered to the Trustee, and any such Securities and coupons and Securities and coupons surrendered directly to the Trustee for any such purpose shall be promptly canceled by it. The Company may at any time deliver to the Trustee for cancellation
any Securities previously authenticated and delivered hereunder 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 not issued and sold, and all Securities so delivered shall be promptly canceled by the Trustee. If the Company shall so acquire any of the Securities, however, such acquisition shall not
operate as a redemption or satisfaction of the indebtedness represented by such Securities unless and until the same are surrendered to the Trustee for cancellation. No Securities shall be authenticated in lieu of or in exchange for any Securities
canceled as provided in this Section, except as expressly permitted by this Indenture. Canceled Securities and coupons held by the Trustee shall be destroyed by the Trustee and, if required in writing by the Company, the Trustee shall deliver a
certificate of such destruction to the Company, unless by a Company Order the Company directs their return to it. 
  

	SECTION 310.	Computation of Interest. 

Except as otherwise specified as contemplated by Section 301 with respect to Securities of any series, interest on the Securities of
each series shall be computed on the basis of a 360-day year consisting of twelve 30-day months. 
  

	SECTION 311.	Deferrals of Interest Payment Dates. 

 If specified as contemplated by Section 201 or Section 301 with respect to the Securities of a particular series, so long as no Event of Default has occurred and is continuing, the Company shall
have the right, at any time during the term of such series, from time to time to defer the payment of interest on such Securities for such period or periods as may be specified as contemplated by Section 301 (each, an “Extension
Period”) during which Extension Periods the Company shall have the right to make partial 

  
 32 

 
payments of interest on any Interest Payment Date. No Extension Period shall end on a date other than an Interest Payment Date. At the end of any such Extension Period the Company shall pay all
interest then accrued and unpaid on the Securities; provided, however, that no Extension Period shall extend beyond the Stated Maturity of the principal of the Securities of such series; provided, further, that during any such Extension Period, the
Company shall not, and shall not permit any Subsidiary to, (i) declare or pay any dividends or distributions on, or redeem, purchase, acquire or make a liquidation payment with respect to, any of the Company’s capital stock, or
(ii) make any payment of principal of or interest or premium, if any, on or repay, repurchase or redeem any debt security of the Company that ranks pari passu in all respects with or junior in interest to the Securities of such series or make
any guarantee payments with respect to any guarantee by the Company of the debt securities of any Subsidiary of the Company that by their terms rank pari passu in all respects with or junior in interest to the securities of such series (other than
(a) repurchases, redemptions or other acquisitions of shares of capital stock of the Company in connection with any employment contract, benefit plan or other similar arrangement with or for the benefit of one or more employees, officers,
directors or consultants, in connection with a dividend reinvestment or stockholder stock purchase plan or in connection with the issuance of capital stock of the Company (or securities convertible into or exercisable for such capital stock) as
consideration in an acquisition transaction entered into prior to any applicable Extension Period, (b) as a result of any exchange or conversion of any class or series of the Company’s capital stock (or any capital stock of a subsidiary of
the Company) for any class or series of the Company’s capital stock or of any class or series of the Company’s indebtedness for any class or series of the Company’s capital stock, (c) the purchase of fractional interests in
shares of the Company’s capital stock pursuant to the conversion or exchange provisions of such capital stock or the security being converted or exchanged, (d) any declaration of a dividend in connection with any stockholder’s rights
plan, or the issuance of rights, stock or other property under any stockholder’s rights plan, or the redemption or repurchase of rights pursuant thereto, or (e) any dividend in the form of stock, warrants, options or other rights where the
dividend stock or the stock issuable upon exercise of such warrants, options or other rights is the same stock as that on which the dividend is being paid or ranks pari passu with or junior to such stock). Prior to the termination of any such
Extension Period, the Company may further defer the payment of interest, provided that no Extension Period shall exceed the period or periods specified in such Securities or extend beyond the Stated Maturity of the principal of such Securities. Upon
termination of any Extension Period and upon the payment of all accrued and unpaid interest then due on any Interest Payment Date, the Company may elect to begin a new Extension Period, subject to the above requirements. No interest shall be due and
payable during an Extension Period, except at the end thereof. The Company shall give the Trustee prior written notice of its election to begin any such Extension Period as specified pursuant to Section 301 at least one Business Day prior to
the next succeeding Interest Payment Date on which interest on Securities of such series would be payable but for such deferral or, with respect to any Securities of a series issued to a Unum Group Trust, so long as any such Securities are held by
such Unum Group Trust, at least one Business Day prior to the earlier of (i) the next succeeding date on which Distributions on the Preferred Securities of such Unum Group Trust would be payable but for such deferral, and (ii) the date on
which the Property Trustee of such Unum Group Trust is required to give notice to any securities exchange or other applicable self-regulatory organization or to holders of such Preferred Securities of the record date or the date such Distributions
are payable. 
 The Trustee, at the expense of the Company, shall promptly give notice of the Company’s election to begin
any such Extension Period to the Holders of the Outstanding Securities of such series. 
  

	SECTION 312.	Right Of Set-Off. 

 With
respect to the Securities of a series issued to a Unum Group Trust, notwithstanding anything to the contrary herein, the Company shall have the right to set-off any payment it is otherwise required to make thereunder in respect of any such Security
to the extent the Company has theretofore made, or is concurrently on the date of such payment, making a payment under the Unum Group Guarantee relating to such Security or to a holder of such Security pursuant to Section 508 hereof.

  
 33 

	SECTION 313.	Agreed Tax Treatment. 

Each Security issued hereunder shall provide that the Company and, by its acceptance of a Security or a beneficial interest therein, the
Holder of, and any Person that acquires a beneficial interest in, such Security agree that for United States Federal, state and local tax purposes it is intended that such Security constitutes indebtedness of the Company for United States Federal,
state and local tax purposes and, with respect to Securities of a series issued to a Unum Group Trust, to treat Preferred Securities of such Trust (including but not limited to all payments and proceeds with respect to such Preferred Securities) as
an undivided beneficial ownership interest in the Securities (and payments and proceeds therefrom, respectively) for United States Federal, state and local tax purposes. The provisions of this Indenture shall be interpreted to further this intention
and agreement of the parties. 
  

	SECTION 314.	Cusip Numbers. 

 The
Company in issuing the Securities may use “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in notices of redemption or other related material as a convenience to Holders; provided that
any such notice or other related material may state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of redemption or other related material and that reliance may
be placed only on the other identification numbers printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers. 

 

	SECTION 315.	Shortening of Stated Maturity. 

 If specified as contemplated by Section 201 or 301 with respect to the Securities of a particular series, the Company shall have the right to shorten the Stated Maturity of the principal of the
Securities of such series at any time to any date not earlier than the first date on which the Company has the right to redeem the Securities of such series. In the event that the Company elects to shorten the Stated Maturity of the Securities of
such series, it shall give written notice to the Trustee. 
 ARTICLE FOUR

shall execute proper instruments acknowledging satisfaction and discharge of this Indenture as to such series and any coupons appertaining thereto when 
 (1) either

 34 

 
coupons of such series which have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 306, (iii) coupons appertaining to Securities called for

theretofore delivered to the Trustee for cancellation 
 (i) have become due and payable, or 

(ii) will become due and payable at their Stated Maturity within one year, or 

(iii) if redeemable at the option of the Company, are to be called for redemption within one year under arrangements
satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company, and the Company, in the case of (i), (ii) or (iii) above, has irrevocably deposited or caused to be
deposited with the Trustee as trust funds in trust for the purpose an amount in the currency or currencies, currency unit or units or composite currency or currencies in which the Securities of such series are payable, sufficient to pay and
discharge the entire indebtedness on such Securities and such coupons not theretofore delivered to the Trustee for cancellation, for principal (and premium or Make-Whole Amount, if any) and interest, and any Additional Amounts with respect thereto,
to the date of such deposit (in the case of Securities which have become due and payable) or the Stated Maturity or Redemption Date, as the case may be; 
 (2) The Company has paid or caused to be paid all other sums payable hereunder by the Company; and 
 (3) The Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and

the Trustee pursuant to subclause (B) of clause (1) of this Section, the obligations of the Trustee under Section 402 and the last paragraph of Section 1003, shall survive. 

In the event that there are Securities of two or more series outstanding hereunder, the Trustee shall be required to execute an
instrument acknowledging satisfaction and discharge of this Indenture only if requested in writing to do so with respect to Securities of a particular series as to which it is Trustee and if the other conditions thereto are met. 

 

	SECTION 402.	Application of Trust Funds. 

 Subject to the provisions of the last paragraph of Section 1003, all money deposited with the Trustee pursuant to Section 401 shall be held in trust and applied by it, in accordance with the
provisions 

  
 35 

 
of the Securities, the coupons and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine,
to the Persons entitled thereto, of the principal (and premium or Make-Whole Amount, if any), and any interest and Additional Amounts for whose payment such money has been deposited with or received by the Trustee, but such money need not be
segregated from other funds except to the extent required by law. Money deposited pursuant to Section 401 not in violation of this Indenture shall not be subject to claims of holders of Senior Debt under Article Seventeen. 

ARTICLE FIVE

obligor or guarantor), having a principal amount outstanding in excess of $10,000,000 (other than indebtedness which is non-recourse to the Company or the Subsidiaries), whether such indebtedness now exists or shall hereafter be created, which
default shall have resulted in such indebtedness being declared due and payable prior to the date on which it would otherwise have become due and payable, without such indebtedness having been discharged, or such acceleration having been rescinded
or annulled, within a period of 30 days after there shall have been given, by registered or certified mail, to the Company by the Trustee or to the Company and the

	SECTION 502.	Acceleration of Maturity; Rescission and Annulment. 

 If an Event of Default with respect to Securities of any series at the time Outstanding occurs and is continuing, then and in every such case the Trustee or the Holders of not less than 25% in aggregate
principal amount of the Outstanding Securities of each such affected series (voting as a single class) may declare the principal and premium, if any, (or, if any Securities are Original Issue Discount Securities or

  
 37 

 
Indexed Securities, such portion of the principal as may be specified in the terms thereof) of, and the Make-Whole Amount, if any, on, all the Securities of that series to be due and payable
immediately, by a notice in writing to the Company (and to the Trustee if given by the Holders), provided that, in the case of the Securities of a series issued to a Unum Group Trust, if, upon an Event of Default, the Trustee or the Holders of not
less than 25% in aggregate principal amount of the Outstanding Securities of that series fail to declare the principal of all the Securities of that series to be immediately due and payable, the holders of at least 25% in aggregate Liquidation
Amount (as defined in the Trust Agreement under which such Unum Group Trust is created) of the corresponding series of Preferred Securities then outstanding shall have such right by a notice in writing to the Company and the Trustee; and upon any
such declaration such principal and premium, if any, or specified portion thereof and the accrued interest shall become immediately due and payable. 
 At any time after such a declaration of acceleration with respect to Securities of any series 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, 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, currency unit or composite
currency in which the Securities of such series are payable (except as otherwise specified pursuant to Section 301 for the Securities of such series): 
 (A) all overdue installments of interest on and any Additional Amounts payable in respect of all Outstanding Securities of that series and any related coupons;

become due otherwise than by such declaration of acceleration and interest thereon at the rate or rates borne by or provided for in such Securities; 
 (C) to the extent that payment of such interest is lawful, interest upon overdue installments of interest and any Additional Amounts at the rate or rates borne by or provided for in such Securities; and

 (D) all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses,

of that series, other than the nonpayment of the principal of (or premium or Make-Whole Amount, if any) or interest on Securities of that series which have become due solely by such declaration of acceleration, have been cured or waived as provided
in Section 513. 
 In the case of Securities of a series issued to a Unum Group Trust, the holders of a majority in
aggregate Liquidation Amount (as defined in the Trust Agreement under which such Unum Group Trust is created) of the related series of Preferred Securities issued by such Unum Group Trust shall also have the right to rescind and annul such
declaration and its consequences by written notice to the Company and the Trustee, subject to the satisfaction of the conditions set forth in Clauses (1) and (2) of this Section 502. 

No such rescission shall affect any subsequent default or impair any right consequent thereon. 

  
 38 

	SECTION 503.	Collection of Indebtedness and Suits for Enforcement by Trustee. 

 The Company covenants that if: 
 (1) default is made in the payment of any
installment of interest or Additional Amounts, if any, on any Security of any series and any related coupon when such interest or Additional Amount becomes due and payable and such default continues for a period of 30 days, or 

(2) default is made in the payment of the principal of (or premium or Make-Whole Amount, if any, on) any Security of any series at its
Maturity, then the Company will, upon demand of the Trustee, pay to the Trustee, for the benefit of the Holders of such Securities of such series and coupons, the whole amount then due and payable on such Securities and coupons for principal (and
premium or Make-Whole Amount, if any) and interest and Additional Amounts, with interest upon any overdue principal (and premium or Make-Whole Amount, if any) and, to the extent that payment of such interest shall be legally enforceable, upon any
overdue installments of interest or Additional Amounts, if any, at the rate or rates borne by or provided for in such Securities, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection,
including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. 
 If the
Company fails to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, and may prosecute such proceeding to
judgment or final decree, and may enforce the same against the Company or any other obligor upon such Securities of such series and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company
or any other obligor upon such Securities of such series, wherever situated. 
 If an Event of Default with respect to
Securities of any series occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders of Securities of such series 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 504.	Trustee May File Proofs of Claim. 

 In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or any other
obligor upon the Securities or the property of the Company or of such other obligor or their creditors, the Trustee (irrespective of whether the principal 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 overdue principal, premium or Make-Whole Amount, if any, or interest, shall be entitled and empowered, by intervention in
such proceeding or otherwise to take any and all actions authorized under the TIA in order to have any claims of the Holders and the Trustee allowed in any such proceeding and: 

(i) to file and prove a claim for the whole amount, or such lesser amount as may be provided for in the Securities of such
series, of principal (and premium or Make-Whole Amount, if any) and interest and Additional Amounts, 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, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders allowed in such judicial proceeding, and 

  
 39 

 (ii) 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 of Securities of such series and coupons 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 to it for the reasonable compensation, expenses, disbursements and advances of the Trustee and any predecessor Trustee, their agents and counsel, and any other amounts due the Trustee or
any predecessor Trustee under Section 606. 
 Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder of a Security or coupon 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 of a Security or coupon in any such proceeding provided, however, that the Trustee may, only on behalf of the Holders, vote for the election of a trustee in bankruptcy or similar official and
be a member of the creditors’ committee or other similar committee. 
  

	SECTION 505.	Trustee May Enforce Claims Without Possession of Securities or Coupons. 

 All rights of action and claims under this Indenture or any of 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 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 506.	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 or Make-Whole Amount, if any) or interest and any Additional Amounts, upon presentation of the Securities or coupons, or both, as the case may be, and the notation thereon of the payment if only partially paid and upon
surrender thereof if fully paid: 
 FIRST: To the payment of all amounts due the Trustee and any predecessor Trustee under
Section 606, 
 SECOND: Subject to Article Seventeen, to the payment of the amounts then due and unpaid upon the Securities
and coupons for principal (and premium or Make-Whole Amount, if any) and interest and any Additional Amounts payable, 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 aggregate amounts due and payable on such Securities and coupons for principal (and premium or Make-Whole Amount, if any), interest and Additional Amounts, respectively, and 

THIRD: To the payment of the remainder, if any, to the Company.

	SECTION 507.	Limitation on Suits. 

 No
Holder of any Security of any series or any related coupon shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder,
unless: 
 (1) such Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to
the Securities of that series; 
 (2) the Holders of not less than 25% in principal amount of the Outstanding Securities of that
series 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 indemnity satisfactory to it against the costs, expenses and liabilities to be incurred in compliance with such request; 

(4) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding;
and 
 (5) no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the
Holders of a majority in principal amount of the Outstanding Securities of that series; it being understood and intended that no one or more of such Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other of such Holders, or to obtain or to seek to obtain priority or preference over any other of such Holders or to enforce any right under this Indenture, except in the manner
herein provided and for the equal and ratable benefit of all such Holders. 
  

	SECTION 508.	Unconditional Right of Holders to Receive Principal, Premium or Make-Whole Amount, if any, Interest and Additional Amounts; Direct Action by Holders of Preferred
Securities. 

 Notwithstanding any other provision in this Indenture, the Holder of any Security or coupon
shall have the right which is absolute and unconditional to receive payment of the principal of (and premium or Make-Whole Amount, if any) and (subject to Sections 305 and 307) interest on, and any Additional Amounts in respect of, such Security or
payment of such coupon on the respective due dates expressed in such Security or coupon (or, in the case of redemption, on the Redemption Date), to convert or exchange such Securities in accordance with Article Sixteen and to institute suit for the
enforcement of any such payment, and such rights shall not be impaired without the consent of such Holder. In the case of Securities of a series issued to a Unum Group Trust, any holder of the corresponding series of Preferred Securities issued by
such Unum Group Trust shall have the right, upon the occurrence of an Event Default described in Section 501(1) or 501(2), to institute a suit directly against the Company for enforcement of payment to such holder of principal of (premium, if
any) and (subject to Section 308 and Section 311) interest on and any Additional Amounts in respect thereof the Securities having a principal amount equal to the aggregate Liquidation Amount (as defined in the Trust Agreement under which
such Unum Group Trust is created) of such Preferred Securities of the corresponding series held by such holder. 
  

	SECTION 509.	Restoration of Rights and Remedies. 

 If the Trustee or any Holder of a Security or coupon or any holder of Preferred Securities 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, to such 

  
 41 

 
Holder or such holder of Preferred Securities, then and in every such case the Company, the Trustee, the Holders of Securities and coupons, and such holder of Preferred Securities shall, subject
to any determination in such proceeding, be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee, the Holders and the holders of Preferred Securities shall continue as though
no such proceeding had been instituted. 
  

	SECTION 510.	Rights and Remedies Cumulative. 

 Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities or coupons in the last paragraph of Section 306, no right or remedy herein
conferred upon or reserved to the Trustee or to the Holders of Securities or 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 511.	Delay or Omission Not Waiver. 

 No delay or omission of the Trustee, of any Holder of any Security or coupon or any holder of any Preferred Security to exercise any right or remedy accruing upon any Event of Default shall impair any
such right or remedy or constitute a waiver of any such Event of Default or any acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders and the right and remedy given to the holders of Preferred
Securities by Section 508 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, or the holders of Preferred Securities, as the case may be. 

 

	SECTION 512.	Control by Holders of Securities. 

 The Holders of not less than a majority in principal amount of the Outstanding Securities of any series shall have the right to direct the time, method and place of conducting any proceeding for any
remedy available to the Trustee or exercising any trust or power conferred on the Trustee with respect to the Securities of such series, provided that 
 (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, and 
 (3) the Trustee need not take any action which might involve it in personal liability or be unduly prejudicial to the Holders of Securities of such series not joining therein (but the Trustee shall have
no obligation as to the determination of such undue prejudice). 
  

	SECTION 513.	Waiver of Past Defaults. 

The Holders of not less than a majority in principal amount of the Outstanding Securities of any series and, in the case of any Securities
of a series issued to a Unum Group Trust, the holders of a Majority in Liquidation Amount (as defined in the Trust Agreement under which such Unum Group Trust is created) of the Preferred Securities issued by such Unum Group Trust may on behalf of
the Holders of all the Securities of such series and any related coupons or all the Preferred Securities issued by such Unum Group Trust consent to the waiver of any past default hereunder with respect to such series and its consequences, except a
default 

  
 42 

 (1) in the payment of the principal of (or premium or Make-Whole Amount, if any) or interest
on or Additional Amounts payable in respect of any Security of such series or any related coupons, 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, 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 shall extend
to any subsequent or other default or Event of Default or impair any right consequent thereon. 
  

	SECTION 514.	Waiver of Stay, Usury 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 usury, stay
or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Company (to the extent that 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.

  

	SECTION 515.	Undertaking for Costs. 

All parties to this Indenture agree, and each Holder of any Security by his acceptance thereof shall be deemed to have agreed, that any
court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in such suit of
an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in such suit having due regard to the merits and good faith of the
claims or defenses made by such party litigant; but the provisions of this Section shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in principal
amount of the Outstanding Securities, or to any suit instituted by any Holder for the enforcement of the payment of the principal of (or premium or Make-Whole Amount, if any) or interest on or Additional Amounts payable with respect to any Security
on or after the respective Stated Maturities expressed in such Security (or in the case of redemption, on or after the Redemption Date) or to enforce the right to convert or exchange any Security in accordance with Article Sixteen.

Within 90 days after the occurrence of any default hereunder with respect to the 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 actually known to a Responsible Officer of the Trustee, unless such default shall 

  
 43 

 
have been cured or waived; provided, however, that, except in the case of a default in the payment of the principal of (or premium or Make-Whole Amount, if any) or interest on or any Additional
Amounts with respect to any Security of such series, or in the payment of any sinking fund installment with respect to the Securities of such series, the Trustee shall be protected in withholding such notice if and so long as Responsible Officers of
the Trustee in good faith determine that the withholding of such notice is in the interests of the Holders of the Securities and coupons of such series; and provided further that in the case of any default or breach of the character specified in
Section 501(4) with respect to the Securities and coupons of such series, no such notice to Holders shall be given until at least 60 days after the occurrence thereof. For the purpose of this Section, the term “default” means any
event which is, or after notice or lapse of time or both would become, an Event of Default with respect to the Securities of such series. 
  

	SECTION 602.	Certain Duties, Responsibilities and Rights of Trustee.

shall be protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, coupon or other paper or document believed by it to
be genuine and to have been signed or presented by the proper party or parties; 
 (3) any request or direction
of the Company mentioned herein shall be sufficiently evidenced by a Company Request or Company Order (other than delivery of any Security, together with any coupons appertaining thereto, to the Trustee for authentication and delivery pursuant to
Section 303 which shall be sufficiently evidenced as provided therein) and any resolution of the Board of Directors may be sufficiently evidenced by a Board Resolution; 

(4) whenever in the administration of this Indenture the Trustee shall deem it desirable that a matter be proved or
established prior to taking, suffering or omitting any action hereunder, the Trustee (unless other evidence be herein specifically prescribed) may, in the absence of bad faith on its part, rely upon an Officers’ Certificate; 

(5) the Trustee may consult with counsel and as a condition to the taking, suffering or omission of any action hereunder
may demand an Opinion of Counsel, and the advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance
thereon; 
 (6) the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by
this Indenture at the request or direction of any of the Holders of Securities of any series or any related coupons pursuant to this Indenture, unless such Holders shall have offered to the Trustee security or indemnity satisfactory to it against
the costs, expenses and liabilities which might be incurred by it in compliance with such request or direction; 

  
 44 

 (7) the Trustee shall not be bound to make any investigation into the facts
or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, coupon or other paper or document, but the Trustee, in its discretion, may make such further

by agent or attorney; 
 (8) the Trustee may execute any of the trusts or powers hereunder or perform any duties
hereunder either directly or by or through agents, attorneys, custodians or nominees and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent, attorney, custodian or nominee appointed with due care by it
hereunder; 
 (9) if the Trustee is acting as Paying Agent or Transfer Agent and Registrar hereunder, the rights,
indemnities and protections afforded to the Trustee pursuant to this Article VI shall also be afforded to such Paying Agent or Transfer Agent and Registrar; 
 (10) the Trustee shall not be deemed to have knowledge of any Event of Default unless the Trustee shall have received written notice, or a Responsible Officer charged with the administration of this
Indenture shall have actual knowledge of such Event of Default; 
 (11) the Trustee shall not be liable for any
action taken, suffered or omitted by it in good faith and reasonably believed by it to be authorized or within the discretion or rights or powers conferred upon it by this Indenture. The Trustee shall not be required to expend or risk its own funds
or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or indemnity satisfactory
to it against such risk or liability is not reasonably assured to it; 
 (12) the Trustee shall not be liable for
special, indirect or consequential loss or damage of any kind whatsoever (including but not limited to lost profits), even if the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action; and 

(13) the Trustee shall not be responsible or liable for any failure or delay in the performance of its obligations under
this Indenture arising out of or caused by, directly or indirectly, forces beyond its control, including without limitation strikes, work stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes
or acts of God, and interruptions, loss or malfunctions of utilities, communications or computer (software or hardware) services. 
  

	SECTION 603.	Not Responsible for Recitals or Issuance of Securities. 

 The recitals contained herein and in the Securities, except the Trustee’s certificate of authentication, and in any coupons shall be taken as the statements of the Company, and neither the Trustee
nor any Authenticating Agent assumes any responsibility for their correctness. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Securities or coupons, except that the Trustee represents that it is
duly authorized to execute and deliver this Indenture, authenticate the Securities and perform its obligations hereunder. Neither the Trustee nor any Authenticating Agent shall be accountable for the use or application by the Company of Securities
or the proceeds thereof. 

  
 45 

	SECTION 604.	May Hold Securities. 

 The
Trustee, any Paying Agent, Security Registrar, Authenticating Agent or any other agent of the Company, in its individual or any other capacity, may become the owner or pledgee of Securities and coupons and, subject to Section 613 and TIA
Sections 310(b) and 311, may otherwise deal with the Company with the same rights it would have if it were not Trustee, Paying Agent, Security Registrar, Authenticating Agent or such other agent. 

 

	SECTION 605.	Money Held in Trust. 

Money held by the Trustee in trust hereunder need not be segregated from other funds except to the extent required by law. The Trustee
shall be under no liability for interest on, or investment of, any money received by it hereunder except as otherwise agreed in writing with the Company. 
  

	SECTION 606.	Compensation and Reimbursement. 

 The Company agrees: 
 (1) to pay to the Trustee from time to time reasonable
compensation for all services rendered by it hereunder, including extraordinary services rendered in connection with or during the continuation of a default hereunder (which compensation shall not be limited by any provision of law in regard to the
compensation of a trustee of an express trust); 
 (2) to reimburse each of the Trustee and any predecessor Trustee upon its
request for all reasonable expenses, disbursements and advances incurred or made by it in accordance with any provision of this Indenture (including the reasonable compensation and the expenses and disbursements of its agents and counsel), except to
the extent any such expense, disbursement or advance may be attributable to its gross negligence or bad faith; and 
 (3) to
indemnify each of the Trustee and any predecessor Trustee and each of their respective directors, officers, agents and employees for, and to hold each of them harmless against, any loss, liability or expense, arising out of or in connection with the
acceptance or administration of the trust or trusts or the performance of its duties hereunder, including the costs and expenses of defending itself against any claim or liability in connection with the exercise or performance of any of its powers
or duties hereunder except to the extent any such loss, liability or expense may be attributable to its own gross negligence or bad faith. 
 As security for the performance of the obligations of the Company under this Section, the Trustee shall have a 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 or Make-Whole Amount, if any) or interest on particular Securities or any coupons. 
 Without prejudice to any other rights available to the Trustee under applicable law, when the Trustee incurs expenses or renders services in connection with an Event of Default described in
Section 501(6) and (7), such expenses (including the fees and expenses of its counsel) and the compensation for such services are intended to constitute expenses of administration under any Bankruptcy Law. 

The provisions of this Section shall survive the termination of this Indenture or the resignation or removal of the Trustee. 

  
 46 

	SECTION 607.	Corporate Trustee Required; Eligibility. 

 There shall at all times be a Trustee hereunder which shall be eligible to act as Trustee under TIA Section 310(a)(1) and shall have a combined capital and surplus of at least $50,000,000. If such
Trustee or Person publishes reports of condition at least annually, pursuant to law or 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 Trustee or Person 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. 
  

	SECTION 608.	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 609. 
 (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 an instrument of acceptance by a successor Trustee 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. 
 (c) The
Trustee may be removed at any time with respect to the Securities of any series by Act of the Holders of 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: 
 (1) the Trustee shall fail to comply with the provisions of Section 613 or TIA Section 310(b) after written request therefor by the Company or by any Holder of a Security who has been a bona
fide Holder of a Security for at least six months, or 
 (2) the Trustee shall cease to be eligible under
Section 607 and shall fail to resign after written request therefor by the Company or by any Holder of a Security who has been a bona fide Holder of a Security for at least six months, or 

(3) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent or a receiver of the Trustee
or of its property shall be appointed or any public officer 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 or pursuant to a Board Resolution may remove the Trustee and appoint a successor Trustee with respect to
all Securities, or (ii) subject to TIA Section 315(e), any Holder of a Security 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 or pursuant to a Board Resolution, shall promptly appoint a successor Trustee or 

  
 47 

 
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) and shall comply with the requirements of Section 609. If, within one year after such resignation, removal or incapacity, 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 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 of Securities and accepted appointment in the manner hereinafter provided, any Holder of a Security 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
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 notices to the Holders of Securities in Section 106.
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 609.	Acceptance of Appointment by Successor. 

 (a) In case of the appointment hereunder of a successor Trustee with respect to all Securities, every such successor Trustee 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 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, if any, provided for
in Section 606. 
 (b) 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, pursuant to Article Nine hereof, 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 that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder

  
 48 

 
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. 

(c) 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) or (b) of this Section, as the case may be. 
 (d) 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 610.	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 of 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 Securities or coupons shall not have been authenticated by such predecessor Trustee, any such successor Trustee may authenticate and deliver such Securities or coupons, in either its own name or that of its predecessor Trustee,
with the full force and effect which this Indenture provides for the certificate of authentication of the Trustee. 
  

	SECTION 611.	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 issued upon exchange, registration of transfer or partial redemption or repayment thereof or pursuant to Section 306, and 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, a copy of
which 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 reasonably
acceptable to the Company and, except as may otherwise be provided pursuant to Section 301, shall at all times be a bank or trust company or corporation organized and doing business and in good standing under the laws of the United States of
America or of any State 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
authorities. If such Authenticating Agent publishes reports of condition at least annually, pursuant 

  
 49 

 
to law or the requirements of the aforesaid supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Authenticating Agent shall be
deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. In case at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, such
Authenticating Agent 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 further act on the part of the Trustee or the Authenticating Agent. 
 An Authenticating Agent for any series of
Securities may at any time resign by giving written notice of resignation to the Trustee for such series and to the Company. The Trustee for any series of Securities may at any time terminate the agency of an Authenticating Agent by giving written
notice of termination 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 for such series may appoint a successor Authenticating Agent which shall be acceptable to the Company and shall give notice of such appointment to all Holders of Securities of or within the series with respect
to which such Authenticating Agent will serve in the manner set forth in Section 106. 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 like effect as if originally named as an Authenticating Agent herein. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section. 

The Company agrees to pay to each Authenticating Agent from time to time reasonable compensation including reimbursement of its
reasonable expenses for its services under this Section. 
 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 or in lieu of the Trustee’s certificate of authentication, an alternate certificate of authentication substantially in the following form:

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

	SECTION 612.	Certain Duties and Responsibilities. 

 No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of
any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such 

  
 50 

 
funds or indemnity satisfactory to it against such risk or liability is not reasonably assured to it. Whether or not therein expressly so provided, every provision of this Indenture relating to
the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section. 
  

	SECTION 613.	Conflicting Interests. 

If the Trustee has or shall acquire a conflicting interest within the meaning of the Trust Indenture Act, the Trustee shall either
eliminate such interest or resign, to the extent and in the manner provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture. To the extent permitted by such Act, the Trustee shall not be deemed to have a conflicting
interest by virtue of being a trustee under this Indenture with respect to Securities of more than one series. In case an Event of Default shall occur and be continuing, the Trustee shall exercise such of its rights and powers under the applicable
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 his own affairs. 

 

	SECTION 614.	Preferential Collection of Claims Against Company. 

 If and when the Trustee shall be or become a creditor of the Company (or any other obligor upon the Securities), the Trustee shall be subject to the provisions of the TIA regarding the collection of
claims against the Company (or any such other obligor). 
 ARTICLE SEVEN

	SECTION 701.	Disclosure of Names and Addresses of Holders. 

 Every Holder of Securities or coupons, by receiving and holding the same, agrees with the Company and the Trustee that neither the Company nor the Trustee nor any Authenticating Agent nor any Paying Agent
nor any Security Registrar nor any director, officer, agent or employee of any of them shall be held accountable by reason of the disclosure of any information as to the names and addresses of the Holders of Securities or coupons in accordance with

A copy of each such report shall, at the time of such transmission to Holders, be filed by the Trustee with the Commission and with the

	SECTION 704.	Company to Furnish Trustee Names and Addresses of Holders. 

 The Company will furnish or cause to be furnished to the Trustee: 
 (1)
semi-annually, not later than 15 days after the Regular Record Date for interest for each series of Securities, a list, in such form as the Trustee may reasonably require, of the names and addresses of the Holders of Registered Securities of such
series as of such Regular Record Date, or if there is no Regular Record Date for interest for such series of Securities, semi-annually, upon such dates as are set forth in the Board Resolution or indenture supplemental hereto authorizing such
series, and 
 (2) at such other times as the Trustee may request in writing, within 30 days after the receipt by the Company of
any such request, a list of similar form and content as of a date not more than 15 days prior to the time such list is furnished, provided however, that, so long as the Trustee is the Security Registrar, no such lists shall be required to be
furnished. 
 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

 ARTICLE EIGHT 

CONSOLIDATION, MERGER, SALE, LEASE OR CONVEYANCE 
  

	SECTION 801.	Consolidations and Mergers of Company and Sales, Leases and Conveyances Permitted Subject to Certain Conditions. 

With respect to any series of Securities, the Company may consolidate with, or sell, lease or convey all or substantially all of its
assets to, or merge with or into any other Person, provided that in any such case, (i) either the Company shall be the continuing entity, or the successor entity (if other than the Company) shall expressly assume the due and punctual payment of
the principal of (and premium or Make-Whole Amount, if any) and any interest (including Additional Amounts, if any, payable pursuant to Section 1011) on all of the Securities of such series, according to their tenor, and the due and punctual
performance and observance of all of the covenants and conditions of this Indenture applicable to such 

  
 52 

 
series to be performed by the Company by supplemental indenture, complying with Article Nine hereof, satisfactory to the Trustee, executed and delivered to the Trustee by such Person, and the
conversion or exchange rights shall be provided for in accordance with Article Sixteen, if applicable, or as otherwise specified pursuant to Section 301; (ii) immediately after giving effect to such transaction and treating any
indebtedness which becomes an obligation of the Company or any Subsidiary as a result thereof as having been incurred by the Company or such Subsidiary at the time of such transaction, no Event of Default applicable to such series, and no event
which, after notice or the lapse of time, or both, would become an Event of Default applicable to such series, shall have occurred and be continuing; and (iii) in the case of the Securities of a series issued to a Unum Group Trust, such
consolidation, merger, conveyance, transfer or lease is permitted under the Trust Agreement under which the Unum Group Trust is created and the related Unum Group Guarantee and does not give rise to any breach or violation of the related Trust
Agreement or Unum Group Guarantee. 
  

	SECTION 802.	Rights and Duties of Successor Corporation. 

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

	SECTION 803.	Officers’ Certificate and Opinion of Counsel. 

 Any consolidation, merger, sale, lease or conveyance permitted under Section 801 is also subject to the condition that the Trustee receive an Officers’ Certificate and an Opinion of Counsel to
the effect that any such consolidation, merger, sale, lease or conveyance, and the assumption by any successor entity, complies with the provisions of this Article and that all conditions precedent herein provided for relating to such transaction
have been complied with.

 (3) to add any additional Events of
Default for the benefit of the Holders of all or any series of Securities (and if such Events of Default are to be for the benefit of less than all series of Securities, stating that such Events of Default are expressly being included solely for the

the case of other defaults) or may provide for an immediate enforcement upon such default or may limit the remedies available to the Trustee upon such default or may limit the right of the Holders of a majority in aggregate principal amount of that
or those series of Securities to which such additional Events of Default apply to waive such default; or

addition, change or elimination shall (i) neither (A) apply to any Security of any series created prior to the execution of such supplemental indenture and entitled to the benefit of such provision, nor (B) modify the rights of the
Holder of any such Security with respect to such provision; or (ii) become effective only when there is no Security Outstanding; or 
 (6) to secure the Securities; or 
 (7) to establish the form or terms of
Securities of any series and any related coupons as permitted by Sections 201 and 301, including the provisions and procedures relating to Securities convertible into or exchangeable for other securities or property of the Company; or 

(8) to evidence and provide for the acceptance of appointment hereunder by a successor Trustee with respect to the Securities of one or
more series and to add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee; or 

(9) to make provision with respect to the conversion or exchange rights of Holders pursuant to the requirements of Article Sixteen,
including providing for the conversion or exchange of the securities into any security or property of the Company; or 

  
 54 

 (10) to cure any ambiguity, to correct or supplement any provision herein which may be
defective or inconsistent with any other provision herein, or to make any other provisions with respect to matters or questions arising under this Indenture which shall not be inconsistent with the provisions of this Indenture or to make any other
changes, provided that in each case, such provisions shall not adversely affect the interests of the Holders of Securities of any series or any related coupons in any material respect or, in the case of the Securities of a series issued to a Unum
Group Trust and for so long as any of the corresponding series of Preferred Securities issued by such Unum Group Trust shall remain outstanding, the holders of such Preferred Securities; or 

(11) to close this Indenture with respect to the authentication and delivery of additional series of Securities or to qualify, or
maintain qualification of, this Indenture under the TIA; or 
 (12) to supplement any of the provisions of this Indenture to
such extent as shall be necessary to permit or facilitate the defeasance and discharge of any series of Securities pursuant to Sections 401, 1402 and 1403; provided in each case that any such action shall not adversely affect the interests of the
Holders of Securities of such series and any related coupons or any other series of Securities in any material respect. 
  

	SECTION 902.	Supplemental Indentures with Consent of Holders. 

 Except as may otherwise be provided pursuant to Section 301 for all or any specific Securities of any series, with the consent of the Holders of not less than a majority in principal amount of all
Outstanding Securities affected by such supplemental indenture, considered together as one class for this purpose (such affected Securities may be Securities of the same or different series and, with respect to any series, may comprise fewer than
all the Securities of such series), by Act of said Holders delivered to the Company and the Trustee, the Company, when authorized by or pursuant to a Board Resolution, and the Trustee may enter into an indenture or indentures supplemental hereto for
the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or of modifying in any manner the rights of the Holders of such affected Securities and any related coupons under this
Indenture; provided, however, that no such supplemental indenture shall, without the consent of the Holder of each Outstanding Security affected thereby: 
 (1) change the Stated Maturity of the principal of (or premium or Make-Whole Amount, if any, on) or any installment of principal of or interest on, any Security; or reduce the principal amount thereof or
the rate or amount of interest thereon or any Additional Amounts payable in respect thereof, or any premium or Make-Whole Amount payable upon the redemption thereof, or change any obligation of the Company to pay Additional Amounts pursuant to
Section 1011 (except as contemplated by Section 801(i) and permitted by Section 901(1)), or reduce the amount of the principal of an Original Issue Discount Security or Indexed Security or Make-Whole Amount, if any, that would be due
and payable upon a declaration of acceleration of the Maturity thereof pursuant to Section 502 or the amount thereof provable in bankruptcy pursuant to Section 504, or adversely affect any right of repayment at the option of the Holder of
any Security, or change any Place of Payment where, or the currency or currencies, currency unit or units or composite currency or currencies in which, the principal of any Security or any premium or Make-Whole Amount or any Additional Amounts
payable in respect thereof or the interest thereon is payable, or impair the right to institute suit for the enforcement of any such payment on or after the Stated Maturity thereof (or, in the case of redemption or repayment at the option of the
Holder, on or after the Redemption Date or the Repayment Date, as the case may be); or 
 (2) educe the percentage in principal
amount of the Outstanding Securities of any series, the consent of whose Holders is required for any such supplemental indenture, or the consent of whose Holders is required for any waiver with respect to such series (or compliance with certain

 55 

 (3) modify any of the provisions of this Section, Section 513 or Section 1012,
except to increase the required percentage to effect such action or to provide that certain other provisions of this Indenture cannot be modified or waived without the consent of the Holder of each Outstanding Security affected thereby; or

 (4) make any change that adversely affects the right to convert or exchange any Security as provided in Article Sixteen or
pursuant to Section 301 (except as permitted by Section 901(9)) or decrease the conversion or exchange rate or increase the conversion or exchange price of any such Security; 
 provided, further, that, in the case of the Securities of a series issued to a Unum Group Trust, so long as any of the corresponding series of Preferred Securities issued by such Unum Group Trust remains

any) of the Securities of such series and all accrued and, subject to Section 307, unpaid interest thereon have been paid in full and (ii) no amendment shall be made to Section 508 of this Indenture that would impair the rights of the
holders of Preferred Securities provided therein without the prior consent of the holders of each Preferred Security then outstanding unless and until the principal (and premium, if any) of the Securities of such series and all accrued and (subject
to Section 307) unpaid interest thereon have been paid in full. 
 A supplemental indenture that changes or eliminates any
covenant or other provision of this Indenture that has expressly been included solely for the benefit of one or more particular series of Securities or Preferred Securities, or which modifies the rights of the Holders of Securities or holders of
Preferred Securities of such series with respect to such covenant or other provision, shall be deemed not to affect the rights under this Indenture of the Holders of Securities or holders of Preferred Securities of any other series. 

It shall not be necessary for any Act of Holders under this Section to approve the particular form of any proposed supplemental
indenture, but it shall be sufficient if such Act shall approve the substance thereof. 
  

	SECTION 903.	Execution of Supplemental Indentures. 

 In executing, or accepting the additional trusts created by, any supplemental indenture permitted by this Article or the modification thereby of the trusts created by this Indenture, the Trustee shall be

 ARTICLE TEN 

COVENANTS 
  

	SECTION 1001.	Payment of Principal, Premium or Make-Whole Amount, if any, Interest and Additional Amounts. 

The Company covenants and agrees for the benefit of the Holders of each series of Securities that it will duly and punctually pay the
principal of (and premium or Make-Whole Amount, if any) and interest on and any Additional Amounts payable in respect of the Securities of that series in accordance with the terms of such series of Securities, any coupons appertaining thereto and
this Indenture. Unless otherwise specified as contemplated by Section 301 with respect to any series of Securities, any interest due on and any Additional Amounts payable in respect of Bearer Securities on or before Maturity, other than
Additional Amounts, if any, payable as provided in Section 1011 in respect of principal of (or premium or Make-Whole Amount, if any, on) such a Security, shall be payable only upon presentation and surrender of the several coupons for such
interest installments as are evidenced thereby as they severally mature. Unless otherwise specified with respect to Securities of any series pursuant to Section 301, at the option of the Company, all payments of principal may be paid by check
to the registered Holder of the Registered Security or other person entitled thereto against surrender of such Security. 

  
 57 

	SECTION 1002.	Maintenance of Office or Agency. 

 If Securities of a series are issued as Registered Securities, the Company shall maintain in each Place of Payment for any series of Securities an office or agency where Securities of that series may be
presented or surrendered for payment or conversion, where Securities of that series may be surrendered for registration of transfer or exchange, where Securities of that series may be converted or exchanged in accordance with Article Sixteen, and
where notices and demands to or upon the Company in respect of the Securities of that series and this Indenture may be served. If Securities of a series are issued as Bearer Securities, the Company will maintain: (A) in the City of Chattanooga,
Tennessee or in the Borough of Manhattan, The City of New York, an office or agency where any Registered Securities of that series may be presented or surrendered for payment or conversion, where any Registered Securities of that series may be
surrendered for exchange, where notices and demands to or upon the Company in respect of the Securities of that series and this Indenture may be served and where Bearer Securities of that series and related coupons may be presented or surrendered
for payment or conversion in the circumstances described in the following paragraph (and not otherwise); (B) subject to any laws or regulations applicable thereto, in a Place of Payment for that series which is located outside the United
States, an office or agency where Securities of that series and related coupons may be presented and surrendered for payment (including payment of any Additional Amounts payable on Securities of that series pursuant to Section 1011) or
conversion; provided, however, that if the Securities of that series are listed on the Luxembourg Stock Exchange, The International Stock Exchange of the United Kingdom or any other stock exchange located outside the United States and such stock
exchange shall so require, the Company will maintain a Paying Agent for the Securities of that series in Luxembourg, London or any other required city located outside the United States, as the case may be, so long as the Securities of that series
are listed on such exchange; and (C) subject to any laws or regulations applicable thereto, in each Place of Payment for that series located outside the United States an office or agency where any Securities of that series may be surrendered
for registration of transfer, where Securities of that series may be surrendered for exchange and where notices and demands to or upon the Company in respect of the Securities of that series 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 each such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the
address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee, except that Bearer Securities of that series and the related coupons may be presented and surrendered for
payment (including payment of any Additional Amounts payable on Bearer Securities of that series pursuant to Section 1011) at the offices specified in the Security, in London, England, and the Company hereby appoints the same as its agent to
receive such respective presentations, surrenders, notices and demands, and the Company hereby appoints the Trustee its agent to receive all such presentations, surrenders, notices and demands. 

Unless otherwise specified with respect to any Securities pursuant to Section 301, no payment of principal, premium, Make-Whole
Amount or interest on or Additional Amounts in respect of 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 any premium and interest on any Bearer Security (including any Additional Amounts or Make-Whole Amount
payable on Securities of such series pursuant to Section 1011) shall be made at the office of the Company’s Paying Agent in the City of Chattanooga, Tennessee or the Borough of Manhattan, The City of New York, if (but only if) payment in
Dollars of the full amount of such principal, premium, interest, Additional Amounts or Make-Whole Amount, as the case may be, at all offices or agencies outside the United States maintained for the purpose by the Company in accordance with this
Indenture, is illegal or effectively precluded by exchange controls or other similar restrictions. 

  
 58 

 The Company may from time to time designate one or more other offices or agencies where the
Securities of one or more series and related coupons, if any, may be presented or surrendered for any or all of such purposes, and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in
any manner relieve the Company of its obligation to maintain an office or agency in accordance with the requirements set forth above for 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 pursuant to Section 301, if and so long as the Securities of any series (i) are denominated in a Foreign Currency or (ii) may be payable in a Foreign Currency, 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 1003.	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 any Securities and any related coupons, it will, on or before each due date of the principal of (and premium or
Make-Whole Amount, if any), or interest on or Additional Amounts in respect of, any of the Securities of that series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum in the currency or currencies, currency unit or
units or composite currency or currencies in which the Securities of such series are payable (except as otherwise specified pursuant to Section 301 for the Securities of such series) sufficient to pay the principal (and premium or Make-Whole
Amount, if any) or interest or Additional Amounts 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, on or before
each due date of the principal of (and premium or Make-Whole Amount, if any), or interest on or Additional Amounts in respect of, any Securities of that series, deposit with a Paying Agent a sum (in the currency or currencies, currency unit or units
or composite currency or currencies described in the preceding paragraph) sufficient to pay the principal (and premium or Make-Whole Amount, if any) or interest or Additional Amounts, so becoming due, such sum to be held in trust for the benefit of
the Persons entitled to such principal, premium, Make-Whole Amount or interest or Additional Amounts 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 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: 
 (1) hold all sums
held by it for the payment of principal of (and premium or Make-Whole Amount, if any) or interest on Securities or Additional Amounts in trust for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise
disposed of as herein provided; 
 (2) give the Trustee written notice of any default by the Company (or any other obligor upon
the Securities) in the making of any such payment of principal (and premium or Make-Whole Amount, if any) or interest or Additional Amounts; and 
 (3) at any time during the continuance of any such default upon the written request of the Trustee, forthwith pay to the Trustee all sums so held in trust by such Paying Agent. 

  
 59 

 The Company may at any time, for the purpose of obtaining the satisfaction and discharge of
this Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be held by the Trustee upon the same trusts as those upon which
such sums were held by the Company or such Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such sums. 

Except as otherwise provided in the Securities of any series, any money deposited with the Trustee or any Paying Agent, or then held by
the Company, in trust for the payment of the principal of (and premium or Make-Whole Amount, if any) or interest on, or any Additional Amounts in respect of, any Security of any series and remaining unclaimed for two years after such principal (and
premium or Make-Whole Amount, if any), interest or Additional Amounts has become due and payable shall be paid to the Company upon Company Request or (if then held by the Company) shall be discharged from such trust; and the Holder of such Security
shall thereafter, as an unsecured general creditor, look only to the Company for payment of such principal of (and premium or Make-Whole Amount, if any) or interest on, or any Additional Amounts in respect of, any Security, without interest thereon,
and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to
make any such repayment, may at the expense of the Company cause to be published once, in an Authorized Newspaper, notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date
of such publication, any unclaimed balance of such money then remaining will be repaid to the Company. 
  

	SECTION 1004.	Restrictions During Extension Period. 

 During any Extension Period, the Company shall not, and shall not permit any Subsidiary to, (i) declare or pay any dividends or distributions on, or redeem, purchase, acquire or make a liquidation
payment with respect to, any of the Company’s capital stock, or (ii) make any payment of principal of or interest or premium, if any, on or repay, repurchase or redeem any debt security of the Company that ranks pari passu in all respects
with or junior in interest to the Securities of such series or make any guarantee payments with respect to any guarantee by the Company of the debt securities of any Subsidiary of the Company that by their terms rank pari passu in all respects with
or junior in interest to the securities of such series (other than (a) repurchases, redemptions or other acquisitions of shares of capital stock of the Company in connection with any employment contract, benefit plan or other similar
arrangement with or for the benefit of one or more employees, officers, directors or consultants, in connection with a dividend reinvestment or stockholder stock purchase plan or in connection with the issuance of capital stock of the Company (or
securities convertible into or exercisable for such capital stock) as consideration in an acquisition transaction entered into prior to any applicable Extension Period, (b) as a result of any exchange or conversion of any class or series of the
Company’s capital stock (or any capital stock of a subsidiary of the Company) for any class or series of the Company’s capital stock or of any class or series of the Company’s indebtedness for any class or series of the Company’s
capital stock, (c) the purchase of fractional interests in shares of the Company’s capital stock pursuant to the conversion or exchange provisions of such capital stock or the security being converted or exchanged, (d) any declaration
of a dividend in connection with any stockholder’s rights plan, or the issuance of rights, stock or other property under any stockholder’s rights plan, or the redemption or repurchase of rights pursuant thereto, or (e) any dividend in
the form of stock, warrants, options or other rights where the dividend stock or the stock issuable upon exercise of such warrants, options or other rights is the same stock as that on which the dividend is being paid or ranks pari passu with or
junior to such stock).

	SECTION 1005.	Existence. 

 Subject to
Article Eight, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect the existence, rights (charter and statutory) and franchises of the Company and its Subsidiaries; provided, however, that the
Company shall not be required to preserve any such right or franchise if the Board of Directors shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and its Subsidiaries as a whole and
that the loss thereof is not disadvantageous in any material respect to the Holders of Securities of any series.

	SECTION 1010.	Statement as to Compliance. 

 The Company will deliver to the Trustee within 120 days after the end of each fiscal year, a brief certificate from the principal executive officer, principal financial officer or principal accounting

 If
any Securities of a series provide for the payment of Additional Amounts, the Company will pay to the Holder of any Security of such series or any coupon appertaining thereto Additional Amounts as may be specified as contemplated by
Section 301. Whenever in this Indenture there is mentioned, in any context except in the case of Section 502(1), the payment of the principal of or any premium, Make-Whole Amount or interest on, or in respect of, any Security of any series
or payment of any related coupon or the net proceeds received on the sale or exchange of any Security of any series, such mention shall be deemed to include mention of the payment of Additional Amounts provided by the terms of such series
established pursuant to Section 301 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 301, 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 any premium is made), and at least 10 days prior to each date of payment of
principal and any premium or Make-Whole Amount or interest if there has been any change with respect to the matters set forth in the below-mentioned Officers’ Certificate, the Company will furnish the Trustee and the Company’s principal
Paying Agent or Paying Agents, if other than the Trustee, with an Officers’ Certificate instructing the Trustee and such Paying Agent or Paying Agents whether such payment of principal of and any 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

  
 61 

 
the Securities of or within the series. If any such withholding shall be required, then such Officers’ Certificate shall specify by country 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, if any, 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 (i) to assume that no such withholding or deduction is required with respect to any payment of
principal or interest with respect to 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 and interest with respect to the Securities of a series
or related coupons without withholding or deductions until otherwise advised. The Company covenants to indemnify the Trustee and any Paying Agent and their respective officers, directors, employees and agents for, and to hold them harmless against,
any loss, liability or expense (including legal fees and expenses) reasonably incurred without gross 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 Officers’
Certificate furnished pursuant to this Section or in reliance on the Company’s not furnishing such an Officers’ Certificate. 
  

	SECTION 1012.	Waiver of Certain Covenants. 

 Subject to the rights of the holders of Preferred Securities specified in Section 902, the Company may omit in any particular instance to comply with any term, provision or condition set forth in
Sections 1004 to 1009, inclusive, and with any other term, provision or condition with respect to the Securities of any series specified in accordance with Section 301, if before or after the time for such compliance the Holders of at least a
majority in principal amount of all outstanding Securities of such series, by Act of such Holders, either waive such compliance in such instance or generally waive compliance with such covenant or condition, but no such waiver shall extend to or
affect such covenant or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the duties of the Trustee in respect of any such term, provision or condition shall remain
in full force and effect. 
  

	SECTION 1013.	Additional Sums. 

 In the
case of the Securities of a series issued to a Unum Group Trust, so long as no Event of Default has occurred and is continuing and except as otherwise specified as contemplated by Section 201 or Section 301, in the event that (i) a
Unum Group Trust is the Holder of all of the Outstanding Securities of such series and (ii) a Tax Event in respect of such Unum Group Trust shall have occurred and be continuing, the Company shall pay to such Unum Group Trust (and its permitted
successors or assigns under the Trust Agreement under which such Unum Group Trust is created) as Holder of the Securities of such series for so long as such Unum Group Trust (or its permitted successor or assignee) is the registered holder of any
Securities of such series, such additional sums as may be necessary in order that the amount of Distributions (including any Additional Amounts (as defined in such Trust Agreement)) then due and payable by such Unum Group Trust on the related
Preferred Securities and Common Securities that at any time remain outstanding in accordance with the terms thereof shall not be reduced as a result of any Additional Taxes (the “Additional Sums”). Whenever in this Indenture or the
Securities there is a reference in any context to the payment of principal of or interest on the Securities, such mention shall be deemed to include mention of the payments of the Additional Sums provided for in this paragraph to the extent that, in
such context, Additional Sums are, were or would be payable in respect thereof pursuant to the provisions of this paragraph and express mention of the payment of Additional Sums (if applicable) in any provisions hereof shall not be construed as
excluding Additional Sums in those provisions hereof where such express mention is not made; provided, however, that the deferral of the payment of interest pursuant to Section 311 or the Securities shall not defer the payment of any Additional
Sums that may be due and payable. 

  
 62 

	SECTION 1014.	Additional Covenants. 

The Company covenants and agrees with each Holder of Securities of each series that it shall not, and it shall not permit any Subsidiary
of the Company to, (a) declare or pay any dividends or distributions on, or redeem, purchase, acquire or make a liquidation payment with respect to, any shares of the Company’s capital stock, or (b) make any payment of principal of or
interest or premium, if any, on or repay, repurchase or redeem any debt securities of the Company that rank pari passu in all respects with or junior in interest to the Securities of such series or make any guarantee payments with respect to any
guarantee by the Company of debt securities of any subsidiary of the Company if such guarantee ranks pari passu in all respects with or junior in interest to the Securities (other than (a) repurchases, redemptions or other acquisitions of
shares of capital stock of the Company in connection with any employment contract, benefit plan or other similar arrangement with or for the benefit of one or more employees, officers, directors or consultants, in connection with a dividend
reinvestment or stockholder stock purchase plan or in connection with the issuance of capital stock of the Company (or securities convertible into or exercisable for such capital stock) as consideration in an acquisition transaction entered into
prior to any applicable Extension Period, (b) as a result of any exchange or conversion of any class or series of the Company’s capital stock (or any capital stock of a subsidiary of the Company) for any class or series of the
Company’s capital stock or of any class or series of the Company’s indebtedness for any class or series of the Company’s capital stock, (c) the purchase of fractional interests in shares of the Company’s capital stock
pursuant to the conversion or exchange provisions of such capital stock or the security being converted or exchanged, (d) any declaration of a dividend in connection with any stockholder’s rights plan, or the issuance of rights, stock or
other property under any stockholder’s rights plan, or the redemption or repurchase of rights pursuant thereto, or (e) any dividend in the form of stock, warrants, options or other rights where the dividend stock or the stock issuable upon
exercise of such warrants, options or other rights is the same stock as that on which the dividend is being paid or ranks pari passu with or junior to such stock), if at such time (i) there shall have occurred any event of which the Company has
actual knowledge that (A) with the giving of notice or the lapse of time or both, would constitute an Event of Default with respect to the Securities of such series and (B) in respect of which the Company shall not have taken reasonable
steps to cure, (ii) if the Securities of such series are held by a Unum Group Trust, the Company shall be in default with respect to its payment of any obligations under the Unum Group Guarantee relating to the Preferred Securities issued by
such Unum Group Trust, or (iii) the Company shall have given written notice of its election to begin an Extension Period with respect to the Securities of such series as provided herein and shall not have rescinded such notice, or such
Extension Period, or any extension thereof, shall be continuing. 
 The Company also covenants with each Holder of Securities of
a series issued to a Unum Group Trust (i) to maintain directly or indirectly 100% ownership of the Common Securities of such Unum Group Trust; provided, however, that any permitted successor of the Company hereunder may succeed to the
Company’s ownership of such Common Securities, (ii) as holder of such Common Securities, not to voluntarily terminate, wind-up or liquidate such Trust, other than (a) in connection with a distribution of the Securities of such series
to the holders of the related Preferred Securities in liquidation of such Trust, or (b) in connection with certain mergers, consolidations or amalgamations permitted by the related Trust Agreement, and (iii) to use its reasonable efforts,
consistent with the terms and provisions of such Trust Agreement, to cause such Unum Group Trust to remain classified as a grantor trust and not an association taxable as a corporation for United States federal income tax purposes. 

 

	SECTION 1015.	Original Issue Discount. 

For each year during which any Securities that were issued with original issue discount are Outstanding, the Company shall furnish to each
Paying Agent in a timely fashion such information as may be reasonably requested by each Paying Agent in order that each Paying Agent may prepare the 

  
 63 

 
information which it is required to report for such year on Internal Revenue Service Forms 1096 and 1099 pursuant to Section 6049 of the Internal Revenue Code of 1986, as amended. Such
information shall include the amount of original issue discount includable in income for each $1,000 of principal amount at Stated Maturity of outstanding Securities during such year. 

ARTICLE ELEVEN 
 REDEMPTION OF SECURITIES 
  

	SECTION 1101.	Applicability of Article. 

Securities of any series which are redeemable before their Stated Maturity shall be redeemable in accordance with their terms and (except
as otherwise specified as contemplated by Section 301 for Securities of any series) in accordance with this Article. 
  

	SECTION 1102.	Election to Redeem; Notice to Trustee. 

 The election of the Company to redeem any Securities, including coupons, if any, shall be evidenced by or pursuant to a Board Resolution. In case of any redemption at the election of the Company, the
Company shall, at least 45 days prior to the giving of the notice of redemption in Section 1104 (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee, in writing, of such Redemption Date, Redemption Price and of the
principal amount of Securities of the series to be redeemed. In the case of any redemption of Securities prior to the expiration of any restriction on such redemption provided in the terms of such Securities or elsewhere in this Indenture or
pursuant to an election of the Company which is subject to a condition specified in the terms of such Securities, the Company shall furnish the Trustee with an Officers’ Certificate and Opinion of Counsel evidencing compliance with such
restriction or condition. 
  

	SECTION 1103.	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 issued on such date with the same terms not previously called for redemption, by such method as the Trustee shall deem fair and appropriate and which may provide for the selection for redemption of portions
(equal to the minimum authorized denomination for Securities of that series or any integral multiple thereof) of the principal amount of Securities of such series of a denomination larger than the minimum authorized denomination for Securities of
that series. The Trustee shall make the selection from Securities of the series that are Outstanding and that have not previously been called for redemption and may provide for the selection for redemption of portions (equal to the minimum
authorized denomination for Securities, including coupons, if any, of that series or any integral multiple thereof). 
 If any
Security selected for partial redemption is converted in part before termination of the conversion or exchange right with respect to the portion of the Security so selected, the converted or exchanged portion of such Security shall be deemed (so far
as may be) to be the portion selected for redemption. Securities which have been converted or exchanged during a selection of Securities to be redeemed shall be treated by the Trustee as Outstanding for the purpose of such selection. In any case
where more than one Security is registered in the same name, the Trustee in its discretion may treat the aggregate principal amount so registered as if it were represented by one Security. 

  
 64 

 The Trustee shall promptly notify the Company and the Security Registrar (if other than
itself) in writing of the Securities selected for redemption and, in the case of any Securities selected for partial redemption, the principal amount thereof to be redeemed. 
 For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities shall relate, in the case of any Security redeemed or to be redeemed only
in part, to the portion of the principal amount of such Security which has been or is to be redeemed. 
  

	SECTION 1104.	Notice of Redemption. 

Notice of redemption shall be given in the manner provided in Section 106, not less than 30 days nor more than 60 days prior to the
Redemption Date, unless a shorter period is specified by the terms of such series established pursuant to Section 301, to each Holder of Securities to be redeemed, but failure to give such notice in the manner herein provided to the Holder of
any Security designated for redemption as a whole or in part, or any defect in the notice to any such Holder, shall not affect the validity of the proceedings for the redemption of any other such Security or portion thereof. 

Any notice that is mailed to the Holders of Registered Securities in the manner herein provided shall be conclusively presumed to have
been duly given, whether or not the Holder receives the notice. 
 All notices of redemption shall state: 

(1) the Redemption Date; 
 (2) the Redemption Price (or if not then ascertainable, the manner of calculation thereof), accrued interest to the Redemption Date payable as provided in Section 1106, if any, and Additional
Amounts, if any; 
 (3) if less than all Outstanding Securities of any series are to be redeemed, the identification (and, in
the case of partial redemption, the principal amount) of the particular Security or Securities to be redeemed; 
 (4) in case
any Security is to be redeemed in part only, that on and after the Redemption Date, upon surrender of such Security, the holder will receive, without a 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 to the Redemption Date
payable as provided in Section 1106, if any, will become due and payable upon each such Security, or the portion thereof, to be redeemed and, if applicable, that interest thereon shall cease to accrue on and after said date; 

(6) the Place or Places of Payment 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, or for conversion or exchange; 
 (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 date 

  
 65 

 
fixed for redemption 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 for such
series 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 the redemption on this Redemption Date pursuant to Section 305 or otherwise, the last date, as determined
by the Company, on which such exchanges may be made; 
 (10) the CUSIP number of such Security, if any, provided that neither
the Company nor the Trustee shall have any responsibility for any such CUSIP number; and 
 (11) if applicable, that a Holder of
Securities who desires to convert or exchange Securities to be redeemed must satisfy the requirements for conversion or exchange contained in such Securities, the then existing conversion or exchange price or rate and the date and time when the
option to convert or exchange shall expire and the place or places where such Securities may be surrendered for conversion. 

Notice of redemption of Securities to be redeemed shall be given by the Company or, at the Company’s written request, by the Trustee
in the name and at the expense of the Company. 
  

	SECTION 1105.	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 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 1003) an amount of money in the currency or currencies, currency unit or units or composite currency or currencies in which the Securities of such series are
payable (except as otherwise specified pursuant to Section 301 for the Securities of such series) 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 on, all the Securities or portions thereof which are to be redeemed on that date. 
  

	SECTION 1106.	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 or
currencies, currency unit or units or composite currency or currencies in which the Securities of such series are payable (except as otherwise specified pursuant to Section 301 for the Securities of such series) (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) 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. Except as provided in the next succeeding paragraph, 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 1002) and, unless otherwise specified as contemplated by Section 301, only upon presentation and surrender of coupons for such interest; and provided further that except as otherwise provided with respect to Securities convertible
or exchangeable into other securities or property of the Company installments of 

  
 66 

 
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 307. 

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 (and any Additional Amounts) represented by coupons shall be payable only at an office or
agency located outside the United States (except as otherwise provided in Section 1002) and, unless otherwise specified as contemplated by Section 301, only upon presentation and surrender of those coupons. If any Security called for
redemption shall not be so paid upon surrender thereof for redemption, the principal, (and premium or Make-Whole Amount, if any) shall, until paid, bear interest from the Redemption Date at the rate borne by the Security. 

 

	SECTION 1107.	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 his attorney duly authorized in writing) and the Company shall execute and the Trustee
shall authenticate and deliver to the Holder of such Security without service charge a new Security or Securities of the same series, 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. 
  

	SECTION 1108.	Right of Redemption of Securities Initially Issued to a Unum Group Trust. 

 In the case of the Securities of a series initially issued to a Unum Group Trust, if specified as contemplated by Section 301, the Company, at its option, may redeem such Securities in whole but not
in part upon the occurrence and during the continuation of a Tax Event or Investment Company Event of such Securities at any time within 90 days following the occurrence of such Tax Event or Investment Company Event in respect of such Unum Group
Trust, in each case at a Redemption Price specified as contemplated by Section 301. 
 ARTICLE TWELVE 

SINKING FUNDS 
  

	SECTION 1201.	Applicability of Article. 

The provisions of this Article shall be applicable to any sinking fund for the retirement of Securities of a series except as otherwise
specified as contemplated by Section 301 for Securities of such series. 
 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 such Securities of any series is herein
referred to as an 

  
 67 

 
“optional sinking fund payment.” If provided for by the terms of any Securities of any series, the cash amount of any mandatory sinking fund payment may be subject to reduction as
provided in Section 1202. 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 1202.	Satisfaction of Sinking Fund Payments with Securities. 

 The Company may, in satisfaction of all or any part of any mandatory sinking fund payment with respect to the Securities of a series, (1) deliver Outstanding Securities of such series (other than any
previously called for redemption) together in the case of any Bearer Securities of such series with all unmatured coupons appertaining thereto and (2) apply as a credit 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, as provided for by the terms of such Securities, or which have otherwise been
acquired by the Company; provided that such Securities so delivered or applied as a credit have not been previously so credited. Such Securities shall be received and credited for such purpose by the Trustee at the applicable 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 1203.	Redemption of Securities for Sinking Fund. 

 Not less than 60 days prior to each sinking fund payment date for Securities of any series, the Company will deliver to the Trustee an Officers’ Certificate specifying the amount of the next ensuing
mandatory 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 or currencies, currency unit or units or composite currency or currencies
in which the Securities of such series are payable (except as otherwise specified pursuant to Section 301 for the Securities of such series) and the portion thereof, if any, which is to be satisfied by delivering and crediting Securities of
that series pursuant to Section 1202, and the optional amount, if any, to be added in cash to the next ensuing mandatory sinking fund payment, and will also deliver to the Trustee any Securities to be so delivered and credited. If such
Officers’ Certificate shall specify an optional amount to be added in cash to the next ensuing mandatory sinking fund payment, the Company shall thereupon be obligated to pay the amount therein specified. Not more than 60 nor less than 30 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 1103 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 1104. Such notice having been duly given, the redemption of such Securities shall be made upon the terms 

ARTICLE THIRTEEN 
 REPAYMENT AT THE OPTION OF HOLDERS 
  

	SECTION 1301.	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, if any, and (except as otherwise specified by the terms of such series established pursuant to Section 301) in accordance with this Article. 

 

	SECTION 1302.	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 a price equal to the 

  
 68 

 
principal amount thereon, together with interest, if any, thereof 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 1003) an amount of money in the currency or currencies,
currency unit or units or composite currency or currencies in which the Securities of such series are payable (except as otherwise specified pursuant to Section 301 for the Securities of such series) sufficient to pay the principal (or, if so
provided by the terms of the Securities of any series, a percentage of the principal) of, and (except if the Repayment Date shall be an Interest Payment Date) accrued interest on, all the Securities or portion thereof, as the case may be, to be
repaid on such date. 
  

	SECTION 1303.	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. In order for any Security to be repaid at the option of the Holder, the Trustee must receive 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 60 days nor later than 30 days prior to the Repayment Date (1) the Security so providing for such repayment together with the “Option to Elect
Repayment” form on the reverse thereof duly completed by the Holder (or by the Holder’s attorney duly authorized in writing) or (2) a telegram, telex, facsimile transmission or a letter from a member of a national securities exchange,
or the National Association of Securities Dealers, Inc. (“NASD”), or a commercial bank or trust company in the United States setting forth the name of the Holder of the Security, the principal amount of the Security, the principal amount
of the Security to be repaid, the CUSIP number, if any, or a description of the tenor and terms of the Security, a statement that the option to elect repayment is being exercised thereby and a guarantee that the Security to be repaid, together with
the duly completed form entitled “Option to Elect Repayment” on the reverse of the Security, will be received by the Trustee not later than the third Business Day after the date of such telegram, telex, facsimile transmission or letter;
provided, however, that such telegram, telex, facsimile transmission or letter shall only be effective if such Security and form duly completed are received by the Trustee by such third Business Day. If less than the entire principal amount of such
Security is to be repaid in accordance with the terms of such Security, the principal amount 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 the principal amount of such Security surrendered that is not to be repaid, must be specified. The principal amount of 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 or within 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 1304.	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

  
 69 

 
Date, the principal amount 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 1002) and, unless otherwise specified pursuant to Section 301,
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 (but without
interest thereon, unless the Company shall default in the payment thereof) 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 307. 
 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 1302 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 1002) and, unless otherwise specified as contemplated by Section 301,
only upon presentation and surrender of those coupons. If the principal amount of any 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 1305.	Securities Repaid in Part. 

Upon surrender of any Registered Security which is to be repaid in part only, the Company shall execute and 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, 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 FOURTEEN 
 DEFEASANCE AND COVENANT DEFEASANCE 
  

	SECTION 1401.	Applicability of Article; Company’s Option to Effect Defeasance or Covenant Defeasance. 

If, pursuant to Section 301, provision is made for either or both of (a) defeasance of the Securities of or within a series
under Section 1402 or (b) covenant defeasance of the Securities of or within a series under Section 1403 to be applicable to the Securities of any series, then the provisions of such Section or Sections, as the case may be, together
with the other provisions of this Article (with such modifications thereto as may be specified pursuant to Section 301 with respect to any Securities), shall be applicable to such Securities and any coupons appertaining thereto, and the Company
may at its option by Board Resolution at any time, with respect to such Securities and any coupons appertaining thereto, elect to defease such Outstanding Securities and any coupons appertaining thereto pursuant to Section 1402 (if applicable)
or Section 1403 (if applicable) upon compliance with the conditions set forth below in this Article. 

  
 70 

	SECTION 1402.	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 and the provisions of Article Seventeen shall cease to be effective with respect to such Outstanding Securities and any coupons appertaining thereto on and after the date the
conditions set forth in Section 1404 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 coupons appertaining thereto, which shall thereafter be deemed to be “Outstanding” only for the purposes of Section 1405 and the other Sections of this Indenture referred to in clauses (A) and
(B) below, and to have satisfied all of its other obligations under such Securities and any coupons appertaining thereto and this Indenture insofar as such Securities and any coupons appertaining thereto 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
coupons appertaining thereto to receive, solely from the trust fund described in Section 1404 and as more fully set forth in such Section, payments in respect of the principal of (and premium or Make-Whole Amount, if any) and interest, if any,
on such Securities and any coupons appertaining thereto when such payments are due, (B) the Company’s obligations with respect to such Securities under Sections 305, 306, 1002 and 1003 and with respect to the payment of Additional Amounts,
if any, on such Securities as contemplated by Section 1011, (C) the rights, powers, trusts, duties and immunities of the Trustee hereunder and (D) this Article. Subject to compliance with this Article Fourteen, the Company may
exercise its option under this Section notwithstanding the prior exercise of its option under Section 1403 with respect to such Securities and any coupons appertaining thereto. 

 

	SECTION 1403.	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 Sections 1005 to 1009, inclusive, and, if specified pursuant to Section 301, its obligations under any other covenant, with respect to such Outstanding Securities and any coupons appertaining
thereto and the provisions of Article Seventeen with respect to such series shall cease to be effective on and after the date the conditions set forth in Section 1404 are satisfied (hereinafter, “covenant defeasance”), and such
Securities and any coupons appertaining thereto shall thereafter be deemed to be not “Outstanding” for the purposes of any direction, waiver, consent or declaration or Act of Holders (and the consequences of any thereof) in connection with
Sections 1005 to 1009, inclusive, or such other covenant, 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 coupons appertaining thereto, 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 Section, Article Seventeen or such other covenant, whether directly or
indirectly, by reason of any reference elsewhere herein to any such Section or such other covenant or by reason of reference in any such Section or such other 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 501(4) or 501(8) or otherwise, as the case may be, but, except as specified above, the remainder of this Indenture and such Securities and any coupons appertaining
thereto shall be unaffected thereby. 

  
 71 

	SECTION 1404.	Conditions to Defeasance or Covenant Defeasance. 

 The following shall be the conditions to application of Section 1402 or Section 1403 to any Outstanding Securities of or within a series and any coupons appertaining thereto:

requirements of Section 607 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 coupons appertaining thereto, (1) an amount in such currency, currencies or currency unit in which such Securities and any coupons appertaining thereto are then specified as
payable at Stated Maturity, or (2) if Securities of such series are not subject to early repayment at the option of the Holders, Government Obligations applicable to such Securities and coupons appertaining thereto (determined on the basis of
the currency, currencies or currency unit in which such Securities and coupons appertaining thereto 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 or Make-Whole Amount, if any) and interest, if any, and Additional Amounts, if any, on such Securities and any coupons appertaining
thereto, money in an amount, or (3) a combination thereof in an amount, sufficient, without consideration of any reinvestment of such principal and interest, 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 or Make-Whole Amount,
if any) and interest, if any, and Additional Amounts, if any, on such Outstanding Securities and any coupons appertaining thereto on the Stated Maturity of such principal or installment of principal or interest and (ii) any mandatory sinking

may give to the Trustee, in accordance with Section 1102 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. 
 (b) Such defeasance or covenant defeasance shall not result in a breach or violation of, or constitute a breach or default under, this Indenture or any other material agreement or instrument to which the
Company is a party or by which it is bound (and shall not cause the Trustee to have a conflicting interest pursuant to Section 310(b) of the TIA with respect to any Security of the Company). 

(c) No Event of Default or event which with notice or lapse of time or both would become an Event of Default with respect to such
Securities and any coupons appertaining thereto shall have occurred and be continuing on the date of such deposit or, insofar as Sections 501(6) and 501(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). 
 (d) In
the case of an election under Section 1402, the Company shall have delivered to the Trustee an Opinion of Counsel stating that (i) the Company has received from, or there has been published by, the Internal Revenue Service a ruling, or
(ii) 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 coupons appertaining thereto will not recognize income, gain or loss for Federal income tax purposes as a result of 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 such defeasance had not occurred. 

  
 72 

 (e) In the case of an election under Section 1403, the Company shall have delivered to
the Trustee an Opinion of Counsel to the effect that the Holders of such Outstanding Securities and any coupons appertaining thereto 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 such covenant defeasance had not occurred. 
 (f) The Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent to the defeasance under Section 1402 or the
covenant defeasance under Section 1403 (as the case may be) have been complied with and an Opinion of Counsel to the effect that either (i) as a result of a deposit pursuant to subsection (a) above and the related exercise of the
Company’s option under Section 1402 or Section 1403 (as the case may be) registration is not required under the Investment Company Act of 1940, as amended, by the Company, with respect to the trust funds representing such deposit or
by the Trustee for such trust funds or (ii) all necessary registrations under said Act have been effected. 
 (g) After the
91st day following the deposit, the trust funds will not be subject to the effect of any applicable bankruptcy, insolvency, reorganization or similar laws affecting creditors’ rights generally. 

(h) The Company shall have delivered an Opinion of Counsel to the effect that the trust funds deposited pursuant to this Section will not
be subject to the rights of any holders of Senior Debt, including those arising under Article Seventeen. 
 (i) 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 which may be imposed on the Company in connection therewith pursuant to
Section 301. 
  

	SECTION 1405.	Deposited Money and Government Obligations to be held in Trust; Other Miscellaneous Provisions. 

Subject to the provisions of the last paragraph of Section 1003, all money and Government Obligations (or other property as may be
provided pursuant to Section 301) (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 1405, the “Trustee”) pursuant to Section 1404 in respect
of any Outstanding Securities of any series and any coupons appertaining thereto shall be held in trust and applied by the Trustee, in accordance with the provisions of such Securities and any coupons appertaining thereto and this Indenture, to the
payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Holders of such Securities and any coupons appertaining thereto of all sums due and to become due
thereon in respect of principal (and premium or Make-Whole Amount, if any) and interest and Additional Amounts, if any, but such money need not be segregated from other funds except to the extent required by law. 

Money and Government Obligations (including the proceeds thereof) so held in trust shall not be subject to the provisions of Article
Seventeen, provided that the applicable conditions of Section 1404 have been satisfied. 
 Unless otherwise specified with
respect to any Security pursuant to Section 301, if, after a deposit referred to in Section 1404(a) 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 301 or the terms of such Security to receive payment in a currency or currency unit other than that in which the deposit pursuant to Section 1404(a) 

  
 73 

 
has been made in respect of such Security, or (b) a Conversion Event occurs in respect of the currency or currency unit in which the deposit pursuant to Section 1404(a) has been made,
the indebtedness represented by such Security and any coupons appertaining thereto shall be deemed to have been, and will be, fully discharged and satisfied through the payment of the principal of (and premium or Make-Whole Amount, if any), and
interest, if any, on such Security as the same becomes 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 or currency unit 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 or currency unit in effect on the second Business Day prior to each
payment date, except, with respect to a Conversion Event, for such currency or currency unit 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 Government Obligations deposited pursuant to Section 1404 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 coupons appertaining thereto. 

Anything in this Article 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 by it as provided in Section 1404 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 a defeasance or covenant defeasance, as applicable, in accordance with this Article. 

 

	SECTION 1406.	Reinstatement. 

 If the
Trustee or the Paying Agent is unable to apply any money or the Government Obligations, as the case may be, in accordance with this Article 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 obligations under this Indenture, such Securities and any coupons appertaining thereto from which the Company has been discharged or released pursuant to Section 1402 or
1403 shall be revived and reinstated as though no deposit had occurred pursuant to this Article with respect to such Securities, until such time as the Trustee or Paying Agent is permitted to apply all money or Government Obligations, as the case
may be, held in trust pursuant to Section 1405 with respect to such Securities and any coupons appertaining thereto in accordance with this Article; provided, however, that if the Company makes any payment of principal of or any
premium or interest on any such Security following such reinstatement of its obligations, the Company shall be subrogated to the rights (if any) of the Holders of such Securities or coupons to receive such payment from the money or Government
Obligations, as the case may be, so held in trust. 
  

	SECTION 1407.	Qualifying Trustee. 

 Any
trustee appointed pursuant to Section 1404 for the purpose of holding trust funds deposited pursuant to that Section shall be appointed under an agreement in form acceptable to the Trustee and shall provide to the Trustee a certificate of such
trustee, upon which certificate the Trustee shall be entitled to conclusively rely, that all conditions precedent provided for herein to the related defeasance or covenant defeasance have been complied with. In no event shall the Trustee be liable
for any acts or omissions of said trustee.

or all series may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such specified percentage of Holders in person or by agent duly appointed in writing; and, except as herein otherwise expressly
provided, such action shall become effective when such instrument or instruments are delivered to the Trustee. Proof of execution of any instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and

 No
fractional shares of securities shall be delivered upon exchanges of Securities of any series. If more than one Security shall be surrendered for exchange at one time by the same Holder, the number of full shares which shall be delivered upon
exchange shall be computed on the basis of the aggregate principal amount of the Securities (or specified portions thereof to the extent permitted hereby) so surrendered. If, except for the provisions of this Section 1603, any Holder of a
Security or Securities would be entitled to a fractional share of a security upon the exchange of such Security or Securities, or specified portions thereof, the Company shall pay to such Holder an amount in cash equal to the current market value of
such fractional share computed on the basis of an average Closing Price of such security. The “Closing Price” of any security on any date of determination means, (i) if such security is listed or admitted to unlisted trading
privileges on a national securities exchange, the last reported sale price regular way on such exchange, (ii) if such security is not at the time so listed, as reported by the NASDAQ National Market, or (iii) if such security is not at the

 78 

 
reclassification, combinations or similar transactions or any consolidation, merger or other reorganization event in accordance with the terms of the supplemental indenture or Board Resolution
setting forth the terms of the Securities of such series. 
 Whenever the exchange rate is adjusted, the Company shall compute
the adjusted exchange rate in accordance with terms of the applicable Board Resolution or supplemental indenture and shall prepare an Officers’ Certificate setting forth the adjusted exchange rate and showing in reasonable detail the facts upon
which such adjustment is based, and such certificate shall forthwith be filed at each office or agency maintained for the purpose of exchange of Securities pursuant to Section 1002 and, if different, with the Trustee. The Company shall
forthwith cause a notice setting forth the adjusted exchange rate to be mailed, first class postage prepaid, to each Holder of Securities of such series at its address appearing on the Security Register and to any exchange agent other than the
Trustee.

securities are registered under Section 12 of the Exchange Act and such issuer is then eligible to use Form S-3 (or any successor form) for a primary offering of its securities) of the Company on exchange of Securities pursuant hereto. The
Company shall not, however, be required to pay any tax which may be payable in respect of any transfer involved in the delivery of shares of securities in a name other than that of the Holder of the Security or Securities to be exchanged, and no
such transfer or delivery shall be made unless and until the person requesting such transfer has paid to the Company the amount of any such tax, or has established, to the satisfaction of the Company, that such tax has been paid. 

 

	SECTION 1606.	Shares Free and Clear. 

The Company hereby warrants that upon exchange of Securities of any series, the Holder of a Security shall receive all rights held by the
Company in such security for which such Security is at such time exchangeable under this Article Sixteen, free and clear of any and all liens, claims, charges and encumbrances other, to the extent permitted by the terms of the Securities of such
series, than any liens, claims, charges and encumbrances which may have been placed on any such security by the prior owner thereof, prior to the time such security was acquired by the Company. Except as provided in Section 1604, the Company
will pay all taxes and charges with respect to the delivery of such security delivered in exchange for Securities hereunder. 
  

	SECTION 1607.	Cancellation of Security. 

Upon receipt by the Trustee of Securities of any series delivered to it for exchange under this Article Sixteen, the Trustee shall cancel
and dispose of the same as provided in Section 309. 
  

	SECTION 1608.	Duties of Trustee Regarding Exchange. 

 Neither the Trustee nor any exchange agent shall at any time be under any duty or responsibility to any Holder of Securities of any series that is exchangeable into other securities or property (including
securities of other issuers, provided that such securities are registered under Section 12 of the Exchange Act and such issuer is then eligible to use Form S-3 (or any successor form) for a primary offering of its securities) of the Company to
determine whether any facts exist which may require any adjustment of the exchange rate, or with respect to the nature or extent of any such adjustment when made, or with respect to the method employed, whether herein or in any supplemental
indenture, any resolutions of the Board of Directors or written instrument executed by one or more officers of the Company provided to be 

  
 79 

 
employed in making the same. Neither the Trustee nor any exchange agent shall be accountable with respect to the validity or value (or the kind or amount) of any securities or property (including
securities of other issuers, provided that such securities are registered under Section 12 of the Exchange Act and such issuer is then eligible to use Form S-3 (or any successor form) for a primary offering of its securities) of the Company, or
of any Securities and neither the Trustee nor any exchange agent makes any representation with respect thereto. Subject to the provisions of Section 612, neither the Trustee nor any exchange agent shall be responsible for any failure of the
Company to issue, transfer or deliver any stock certificates or other securities or property (including securities of other issuers, provided that such securities are registered under Section 12 of the Exchange Act and such issuer is then
eligible to use Form S-3 (or any successor form) for a primary offering of its securities) upon the surrender of any Security for the purpose of exchange or to comply with any of the covenants of the Company contained in this Article Sixteen or in
the applicable supplemental indenture, resolutions of the Board of Directors or written instrument executed by one or more duly authorized officers of the Company. 
  

	SECTION 1609.	Repayment of Certain Funds Upon Exchange. 

 Any funds which at any time shall have been deposited by the Company or on its behalf with the Trustee or any other paying agent for the purpose of paying the principal of, and premium, if any, and
interest, if any, on any of the Securities (including funds deposited for the sinking fund referred to in Article Twelve hereof) and which shall not be required for such purposes because of the exchange of such Securities as provided in this Article
Sixteen shall after such exchange be repaid to the Company by the Trustee upon the Company’s written request. 
  

	SECTION 1610.	Exercise of Conversion Privilege. 

 In order to exercise a conversion or exchange privilege, the Holder of a Security of a series with such a privilege shall surrender such Security to the Company at the office or agency maintained for that
purpose pursuant to Section 1002, accompanied by written notice to the Company that the Holder elects to convert or exchange such Security or a specified portion thereof. Such notice shall also state, if different from the name or names (with
address) in which the Securities are registered, the name or names in which the securities or property (including securities of other issuers, provided that such securities are registered under Section 12 of the Exchange Act and such issuer is
then eligible to use Form S-3 (or any successor form) for a primary offering of its securities) of the Company which shall be issuable on such conversion or exchange shall be issued. Securities surrendered for conversion or exchange shall (if so
required by the Company or the Trustee) be duly endorsed by or accompanied by instruments of transfer in forms satisfactory to the Company and the Trustee duly executed by the registered Holder or its attorney duly authorized in writing; and
Securities so surrendered for conversion or exchange during the period from the close of business on any Regular Record Date to the opening of business on the next succeeding Interest Payment Date (excluding Securities or portions thereof called for
redemption during such period) shall also be accompanied by payment in funds acceptable to the Company of an amount equal to the interest payable on such Interest Payment Date on the principal amount of such Security then being converted, and such
interest shall be payable to such registered Holder notwithstanding the conversion or exchange of such Security, subject to the provisions of Section 307 relating to the payment of Defaulted Interest by the Company. As promptly as practicable
after the receipt of such notice and of any payment required pursuant to a Board Resolution and, subject to Section 303, set forth, or determined in the manner provided, in an Officers’ Certificate, or established in one or more indentures
supplemental hereto setting forth the terms of such series of Security, and the surrender of such Security in accordance with such reasonable regulations as the Company may prescribe, the Company shall issue and shall deliver, at the office or
agency at which such Security is surrendered, to such Holder or on its written order, securities or property (including securities of other issuers, provided that such securities are registered under Section 12 of the Exchange Act and such
issuer is then eligible to use Form S-3 (or any 

  
 80 

 
successor form) for a primary offering of its securities) of the Company issuable or deliverable upon the conversion or exchange of such Security (or specified portion thereof), in accordance
with the provisions of such Board Resolution, Officers’ Certificate or supplemental indenture, and cash as provided therein in respect of any fractional share of such common stock otherwise issuable upon such conversion or exchange. Such
conversion or exchange shall be deemed to have been effected immediately prior to the close of business on the date on which such notice and such payment, if required, shall have been received in proper order for conversion or exchange by the
Company and such Security shall have been surrendered as aforesaid (unless such Holder shall have so surrendered such Security and shall have instructed the Company to effect the conversion or exchange on a particular date following such surrender
and such Holder shall be entitled to convert or exchange such Security on such date, in which case such conversion or exchange shall be deemed to be effected immediately prior to the close of business on such date) and at such time the rights of the
Holder of such Security as such Security Holder shall cease and the person or persons in whose name or names any securities or property (including securities of other issuers, provided that such securities are registered under Section 12 of the
Exchange Act and such issuer is then eligible to use Form S-3 (or any successor form) for a primary offering of its securities) of the Company shall be issuable or deliverable upon such conversion or exchange shall be deemed to have become the
Holder or Holders of record of the shares represented thereby. Except as set forth above and subject to the final paragraph of Section 307, no payment or adjustment shall be made upon any conversion or exchange on account of any interest
accrued on the Securities surrendered for conversion or exchange or on account of any interest or dividends on the securities or property (including securities of other issuers, provided that such securities are registered under Section 12 of
the Exchange Act and such issuer is then eligible to use Form S-3 (or any successor form) for a primary offering of its securities) of the Company issued or delivered upon such conversion or exchange. 

In the case of any Security which is converted or exchanged in part only, upon such conversion or exchange the Company shall execute and
the Trustee shall authenticate and deliver to or on the order of the Holder thereof, at the expense of the Company, a new Security or Securities of the same series, of authorized denominations, in aggregate principal amount equal to the unconverted
or unexchanged portion of such Security. 
  

	SECTION 1611.	Effect of Consolidation or Merger on Conversion Privilege. 

 In case of any consolidation of the Company with, or merger of the Company into or with any other Person, or in case of any sale of all or substantially all of the assets of the Company, the Company or
the Person formed by such consolidation or the Person into which the Company shall have been merged or the Person which shall have acquired such assets, as the case may be, shall execute and deliver to the Trustee a supplemental indenture providing
that the Holder of each Security then outstanding of any series that is convertible into common stock of the Company shall have the right, which right shall be the exclusive conversion right thereafter available to said Holder (until the expiration
of the conversion right of such Security), to convert such Security into the kind and amount of shares of stock or other securities or property (including cash) receivable upon such consolidation, merger or sale by a holder of the number of shares
of common stock of the Company into which such Security might have been converted immediately prior to such consolidation, merger or sale, subject to compliance with the other provisions of this Indenture, such Security and such 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 such Security. The above provisions of this Section shall similarly apply to successive
consolidations, mergers or sales. It is expressly agreed and understood that anything in this Indenture to the contrary notwithstanding, if, pursuant to such merger, consolidation or sale, holders of outstanding shares of common stock of the Company
do not receive shares of common stock of the surviving corporation but receive other securities, cash or other property or any combination thereof, Holders of Securities shall not have the right to thereafter convert their Securities into common
stock of 

  
 81 

 
the surviving corporation or the corporation which shall have acquired such assets, but rather, shall have the right upon such conversion to receive the other securities, cash or other property
receivable by a holder of the number of shares of common stock of the Company into which the Securities held by such holder might have been converted immediately prior to such consolidation, merger or sale, all as more fully provided in the first
sentence of this Section 1611. Anything in this Section 1611 to the contrary notwithstanding, the provisions of this Section 1611 shall not apply to a merger or consolidation of another corporation with or into the Company pursuant to
which both of the following conditions are applicable: (i) the Company is the surviving corporation and (ii) the outstanding shares of common stock of the Company are not changed or converted into any other securities or property
(including cash) or changed in number or character or reclassified pursuant to the terms of such merger or consolidation. 
 As
evidence of the kind and amount of shares of stock or other securities or property (including cash) into which Securities may properly be convertible after any such consolidation, merger or sale, or as to the appropriate adjustments of the
conversion prices applicable with respect thereto, the Trustee shall be furnished with and may accept the certificate or opinion of an independent certified public accountant with respect thereto; and, in the absence of bad faith on the part of the
Trustee, the Trustee may conclusively rely thereon, and shall not be responsible or accountable to any Holder of Securities for any provision in conformity therewith or approved by such independent certified accountant which may be contained in said
supplemental indenture. 
 ARTICLE SEVENTEEN 
 SUBORDINATION 
  

	SECTION 1701.	Agreement to Subordinate. 

Except as otherwise provided in a supplemental indenture or pursuant to Section 301, the Company agrees, and each Holder by accepting
a Security agrees, that the indebtedness evidenced by the Securities is subordinated in right of payment, to the extent and in the manner provided in this Article, to the prior payment in full of all Senior Debt and that the subordination is for the
benefit of the holders of Senior Debt. 
 Notwithstanding the foregoing, if a deposit referred to in
Section 1404(a) is made pursuant to Section 1402 or Section 1403 with respect to any Securities (and provided all other conditions set out in Section 1402 or 1403, as applicable, shall have been satisfied with respect to such
Securities), then, when the 91st day after such deposit
has ended, no money or Government Obligations so deposited, and no proceeds thereon, will be subject to any rights of holders of Senior Debt, including any such rights arising under this Article Seventeen. 

 

	SECTION 1702.	Liquidation; Dissolution; Bankruptcy. 

 In the event of (a) any insolvency or bankruptcy case or proceeding, or any receivership, liquidation, reorganization or other similar case or proceeding in connection therewith, relative to the
Company or to its creditors, as such, or to its assets, or (b) any liquidation, dissolution or other winding up of the Company, whether voluntary or involuntary and whether or not involving insolvency or bankruptcy, or (c) any assignment
for the benefit of creditors or any other marshalling of assets and liabilities of the Company: 
 (1) holders of Senior Debt
shall be entitled to receive payment in full in cash of the principal thereof, premium, if any, Additional Amounts, if any, and interest (including interest accruing after the commencement of any such proceeding) to the date of payment on the Senior
Debt before Holders shall be entitled to receive any payment of principal of or interest on Securities; 

  
 82 

 (2) until the Senior Debt is paid in full in cash, any distribution to which Holders or the
Trustee would be entitled but for this Article shall be made to holders of Senior Debt as their interests may appear for the application to the payment thereof, except that Holders may receive securities that are subordinated to Senior Debt to at
least the same extent as the Securities; and 
 (3) the Trustee is entitled to conclusively rely upon an order or decree of a
court of competent jurisdiction or a certificate of a bankruptcy trustee or other similar official for the purpose of ascertaining the persons entitled to participate in such distribution, the holders of Senior Debt and other Company debt, the
amount thereof or payable thereon and all other pertinent facts relating to the Trustee’s obligations under this Article Seventeen. 
 In the event that, notwithstanding the foregoing provisions of this Section, the Trustee or the Holder of any Security shall have received any payment or distribution of assets of the Company of any kind
or character, whether in cash, property or securities, including any such payment or distribution which may be payable or deliverable by reason of the payment of any other indebtedness of the Company being subordinated to the payment of the
Securities, before all Senior Debt is paid in full or payment thereof provided for, and if such fact shall, at or prior to the time of such payment or distribution, have been made known to a Responsible Officer of the Trustee in writing or, as the
case may be, such Holder, then and in such event such payment or distribution shall be paid over or delivered forthwith to the trustee in bankruptcy, receiver, liquidating trustee, custodian, assignee, agent or other Person making payment or
distribution of assets of the Company for application to the payment of all Senior Debt remaining unpaid, to the extent necessary to pay all Senior Debt in full, after giving effect to any concurrent payment or distribution to or for the holders of
Senior Debt. Any taxes that have been withheld or deducted from any payment or distribution in respect of the Securities, or any taxes that ought to have been withheld or deducted from any such payment or distribution that have been remitted to the
relevant taxing authority, shall not be considered to be an amount that the Trustee or the Holder of any Security receives for purposes of this Section. 
  

	SECTION 1703.	Default on Senior Debt. 

The Company may not pay principal, premium, interest or Additional Amounts on the Securities and may not acquire any Securities for cash
or property other than capital stock of the Company if: 
 (1) (a) in the event and during the continuation of any default in
the payment of principal, premium, if any, or interest on any Senior Debt beyond any applicable grace period with respect thereto or (b) a default on Senior Debt occurs and is continuing that permits holders of such Senior Debt (or a trustee on
their behalf) to accelerate its maturity, or 
 (2) the default is the subject of judicial proceedings or the Company receives a
notice of the default from a person who may give it pursuant to Section 1711. If the Company receives any such notice, a similar notice received within nine months thereafter relating to the same default on the same issue of Senior Debt shall
not be effective for purposes of this Section. 
 The Company may resume payments on the Securities and may acquire them when:

 (a) the default is cured or waived, or 

(b) 120 days pass after the notice is given if the default is not the subject of judicial proceedings. 

if this Article otherwise permits the payment or acquisition at that time. 

  
 83 

	SECTION 1704.	Acceleration of Securities. 

 In the event that any Securities are declared due and payable before their Stated Maturity, then and in such event the holders of Senior Debt shall be entitled to receive payment in full of all amounts
due or to become due on or in respect of all Senior Debt or provision shall be made for such payment in cash, before the Holders of the Securities are entitled to receive any payment (including any payment which may be payable by reason of the
payment of any other indebtedness of the Company being subordinated to the payment of the Securities) by the Company on account of the principal of, premium, if any, Additional Amounts, if any or interest on the Securities or on account of the
purchase or other acquisition of Securities; provided, however, that nothing in this Section shall prevent the satisfaction of any sinking fund payment in accordance with Article Twelve by delivering and crediting pursuant to Section 1202
Securities which have been acquired (upon redemption or otherwise) prior to such declaration of acceleration; provided, further, money deposited pursuant to Section 402 not in violation of this Indenture shall not be subject to the claims of
holders of Senior Debt. 
 In the event that, notwithstanding the forgoing, the Company shall make any payment to the Trustee or
the Holder of any Security prohibited by the foregoing provisions of this Section, and if such fact shall, at or prior to the time of such payment, have been made known to a Responsible Officer of the Trustee in writing or, as the case may be, such
Holder, then and in such event such payment shall be paid over and delivered forthwith to the Company. 
  

	SECTION 1705.	When Distribution Must be Paid Over. 

 If a distribution is made to Holders that because of this Article should not have been made to them, the Holders who receive the distribution shall hold it in trust for holders of Senior Debt and pay it
over to them as their interests may appear. 
  

	SECTION 1706.	Notice by Company. 

 The
Company shall promptly notify the Trustee, in writing, and any Paying Agent of any facts known to the Company that would cause a payment on the Securities to violate this Article. 

 

	SECTION 1707.	Subrogation. 

 After all
Senior Debt is paid in full and until the Securities are paid in full, Holders shall be subrogated to the rights of holders of Senior Debt to receive payments or distributions applicable to Senior Debt to the extent that distributions otherwise
payable to the Holders have been applied to the payment of Senior Debt. A payment or distribution made under this Article to holders of Senior Debt which otherwise would have been made to Holders is not, as among the Company, its creditors other
than the holders of Senior Debt and Holders, a payment or distribution by the Company on account of the Senior Debt. 
  

	SECTION 1708.	Relative Rights. 

 This
Article is intended solely to define the relative rights of Holders on the one hand and the holders of Senior Debt on the other hand. Nothing in this Indenture or in the Securities shall: 

(1) impair, as among the Company, its creditors other than holders of Senior Debt and the Holders of the Securities, the obligation of
the Company, which is absolute and unconditional, to pay to the Holders of the Securities the principal of, premium, if any, Additional Amounts, if any, and interest on the Securities as and when the same shall become due and payable in accordance
with their terms; 

  
 84 

 (2) affect the relative rights of Holders and creditors of the Company other than holders of
Senior Debt; or 
 (3) prevent the Trustee or any Holder (or to the extent expressly provided herein, the holder of any
Preferred Security) from exercising its available remedies upon an Event of Default, subject to the rights of holders of Senior Debt to receive payments or distributions otherwise payable to Holders or the Trustee. 

If the Company fails because of this Article to pay principal, premium, if any, Additional Amounts, if any, or interest on a Security on
the due date, such failure shall constitute a default hereunder. 
  

	SECTION 1709.	Subordination May Not be Impaired by Company. 

 No right of any holder of Senior Debt to enforce the subordination of the indebtedness evidenced by the Securities shall be impaired by any act or failure to act by the Company or by its failure to comply
with this Indenture. 
  

	SECTION 1710.	Distribution or Notice to Representative. 

 Whenever a distribution is to be made or a notice given to holders of Senior Debt, the distribution may be made and the notice given to their Representative. 

 

	SECTION 1711.	Rights of Trustee and Paying Agent. 

 The Trustee or any Paying Agent may continue to make payments on the Securities until it receives written notice of facts that would cause a payment of principal of or interest on the Securities to
violate this Article. Only the Company, a Representative or a holder of an issue of Senior Debt that has no Representative may give the written notice. 
 The Trustee has no fiduciary duty to the holders of Senior Debt other than as created under this Indenture. The Trustee in its individual or any other capacity may hold Senior Debt with the same rights it
would have if it were not Trustee. 
 The Company’s obligation to pay, and the Company’s payment of, the amounts
required by Section 606 are excluded from the operation of this Article Seventeen. 
  

	SECTION 1712.	Payment Permitted in Certain Situations. 

 Nothing contained in this Article or elsewhere in this Indenture or in any of the Securities shall prevent (a) the Company, at any time except during the pendency of any case, proceeding,
dissolution, liquidation or other winding up, assignment for the benefit of creditors or other marshalling of assets and liabilities of the Company referred to in Section 1702 or under the conditions described in Section 1703 or 1704, from
making payments at any time of or on account of the principal of, premium, if any, Additional Amounts, if any or interest on the Securities or on account of the purchase or other acquisition of the Securities, or (b) the application by the
Trustee of any money deposited with it hereunder to the payment of or on account of the principal of, premium, if any, Additional Amounts, if any, or interest on the Securities or the retention of such payment by the Holders, if, at the time of such
application by the Trustee, it did not have knowledge (in accordance with Section 1706) that such payment would have been prohibited by the provisions of this Article. 

  
 85 

	SECTION 1713.	Trustee to Effectuate Subordination. 

 Each Holder of a Security by his acceptance thereof authorizes and directs the Trustee on his behalf to take such action as may be necessary or appropriate to effectuate the subordination provided in this
Article and appoints the Trustee his attorney-in-fact for any and all such purposes. 
  

	SECTION 1714.	Reliance on Judicial Order or Certificate of Liquidating Agent. 

 Upon any payment or distribution of assets of the Company referred to in this Article, the Trustee, subject to the provisions of Section 601, and the Holders of the Securities shall be entitled to
conclusively rely upon any order or decree entered by any court of competent jurisdiction in which such insolvency, bankruptcy, receivership, liquidation, reorganization, dissolution, winding up or similar case or proceeding is pending, or a
certificate of the trustee in bankruptcy, receiver, liquidating trustee, custodian, assignee for the benefit of creditors, agent or other Person making such payment or distribution, delivered to the Trustee or to the Holders of Securities, for the
purpose of ascertaining the Persons entitled to participate in such payment or distribution, the holders of Senior Debt and other indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon
and all other facts pertinent thereto or to this Article. The Trustee shall be entitled to rely on the delivery to it of a written notice by a Person representing himself to be a holder of Senior Debt or a Representative therefor to establish that
such notice has been given by a holder of such Senior Debt or such Representative on behalf of such holder. In the event that the Trustee determines in good faith that further evidence is required with respect to the right of any Person as a holder
of Senior Indebtedness to participate in any payment or distribution pursuant to this Article Seventeen, the Trustee may request such Person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of Senior Debt held by
such Person, the extent to which such Person is entitled to participate in such payment or distribution and any other facts pertinent to the right of such Person under this Article Seventeen, and, if such evidence is not furnished, the Trustee may
defer any payment to such Person pending judicial determination as to the right of such Person to receive such payment or distribution. 
  

	SECTION 1715.	Article Applicable to Paying Agents. 

 In case at any time any Paying Agent other than the Trustee shall have been appointed by the Company and be then acting hereunder, the term “Trustee” as used in this Article shall in such case
(unless the context otherwise requires) be construed as extending to and including such Paying Agent within its meaning as fully for all intents and purposes as if such Paying Agent were named in this Article in addition to or in place of the
Trustee. 
 This Indenture 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 Indenture. 

  
 86 

 IN WITNESS WHEREOF, the parties hereto have caused this Indenture to be duly executed by
their respective officers hereunto duly authorized, all as of the day and year first above written.

Security of such series) only upon receipt of certain certificates or other documents or satisfaction of other conditions, the form and terms of such certificates, documents or conditions; 

(r) any trustees, depositaries, authenticating or paying agents, transfer agents or registrars or any other agents with respect to the
Securities of such series; 
 (s) any applicable United States federal income tax and Israel income tax provisions, including,
but not limited to: whether and under what circumstances the Issuer will pay additional amounts on Securities for any tax, assessment or governmental charge withheld or deducted and, if so, whether it will have the option to redeem those Securities
rather than pay the additional amounts; tax considerations applicable to any discounted Securities or to Securities issued at par that are treated as having been issued at a discount for United States federal income tax purposes; and tax
considerations applicable to any Securities denominated and payable in foreign currencies; 
 (t) whether certain payments on the
Securities will be guaranteed under a financial insurance guaranty policy and the terms of that guaranty; 
 (u) any applicable
selling restrictions; 
 (v) any other events of default, modifications or elimination of any acceleration rights, or covenants
with respect to the Securities of such series and any terms required by or advisable under applicable laws or regulations, including laws and regulations relating attributes required for the Securities to be afforded certain capital treatment for
bank regulatory or other purposes; and 
 (w) any other terms of the series. 

All Securities of any one series shall be substantially identical except as to denomination and except as may otherwise be provided in or
pursuant to such resolution of the Board or in any such indenture supplemental hereto. All Securities of any one series need not be issued at the same time and may be issued from time to time, consistent with the terms of this Indenture, if so
provided by or pursuant to such Board Resolution or in any such indenture supplemental hereto.

 Section 2.04. Authentication and Delivery of Securities. At any time and from time to
time after the execution and delivery of this Indenture, the Issuer may deliver Securities of any series executed by the Issuer to the Trustee for authentication, and the Trustee shall thereupon authenticate and deliver such Securities to or upon
the written order of the Issuer, signed by any two officers of the Issuer authorized by the Board to execute any such order, without any further action by the Issuer. 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 (subject to Section 5.01) shall be fully protected in relying upon: 
 (a) a certified copy of any resolution or resolutions of the Board authorizing the action taken pursuant to the resolution or resolutions delivered under clause 2.04(b) below; 

(b) a copy of any resolution or resolutions of the Board relating to such series, in each case certified by the Secretary or an Assistant
Secretary of the Issuer; 
 (c) an executed supplemental indenture, if any; 

(d) an Officers’ Certificate setting forth the form and terms of the Securities as required pursuant to Sections 2.01 and 2.03,
respectively and prepared in accordance with Section 10.05; 
 (e) an Opinion of Counsel, prepared in accordance with
Section 10.05, 
 (i) to the effect that the form or forms and terms of such Securities have been
established by or pursuant to a resolution of the Board or by a supplemental indenture as permitted by Sections 2.01 and 2.03 in conformity with the provisions of this Indenture; 

(ii) to the effect that such Securities, when authenticated and delivered by the Trustee and issued by the Issuer in the
manner and subject to any conditions specified in such Opinion of Counsel, will constitute valid and binding obligations of the Issuer; and 
 (iii) covering such other matters as the Trustee may reasonably request. 
 The
Trustee shall have the right to decline to authenticate and deliver any Securities under this Section if the Trustee, being advised by counsel, determines that such action may not lawfully be taken by the Issuer or if the Trustee in good faith shall
determine that such action would expose the Trustee to personal liability to existing Holders. 
 Section 2.05. Execution of
Securities. The Securities shall be signed on behalf of the Issuer by any two officers of the Issuer authorized by the Board to execute such Securities, which Securities may, but need not, be attested. Such signatures may be the manual or
facsimile signatures of the present or any future such officers. Typographical and other minor errors or defects in any such signature shall not affect the validity or enforceability of any Security that has been duly authenticated and delivered by
the Trustee. 
 In case any officer of the Issuer who shall have signed any of the Securities shall cease to be such officer
before the Security so signed shall be authenticated and delivered by the Trustee or disposed of by the Issuer, such Security nevertheless may be authenticated and delivered or disposed of as though the person who signed such Security had not ceased
to be such officer of the Issuer; and any 

  
 8 

 
Security may be signed on behalf of the Issuer by such persons as, at the actual date of the execution of such Security, shall be the proper officers of the Issuer, although at the date of the
execution and delivery of this Indenture any such person was not such an officer. 
 Section 2.06. Certificate of
Authorization. Only such Securities as shall bear thereon a certificate of authentication substantially in the form hereinbefore recited, executed by the Trustee by the manual signature of one of its authorized officers, shall be entitled to the
benefits of this Indenture or be valid or obligatory for any purpose. Such certificate by the Trustee upon any Security executed by the Issuer shall be conclusive evidence that the Security so authenticated has been duly authenticated and delivered
hereunder and that the holder is entitled to the benefits of this Indenture. 
 Section 2.07. Denomination and Date of
Securities; Payments of Interest. The Securities shall be issuable as registered securities without coupons and in denominations as shall be specified as contemplated by Section 2.03. In the absence of any such specification with respect to
the Securities of any series, the Securities of such series shall be issuable in denominations of $1,000 and any multiple thereof. The Securities shall be numbered, lettered, or otherwise distinguished in such manner or in accordance with such plan
as the officers of the Issuer executing the same may determine with the approval of the Trustee as evidenced by the execution and authentication thereof. 
 Each Security shall be dated the date of its authentication, shall bear interest, if any, from the date and shall be payable on the dates, in each case, which shall be specified as contemplated by
Section 2.03. 
 The person in whose name any Security of any series is registered at the close of business on any record
date applicable to a particular series with respect to any interest payment date for such series shall be entitled to receive the interest, if any, payable on such interest payment date notwithstanding any transfer or exchange of such Security
subsequent to the record date and prior to such interest payment date, except if and to the extent the Issuer and the Guarantor shall default in the payment of the interest due on such interest payment date for such series, in which case such
defaulted interest shall be paid to the persons in whose names Outstanding Securities for such series are registered at the close of business on a subsequent record date (which shall be not less than five Business Days prior to the date of payment
of such defaulted interest) established by notice given by mail by or on behalf of the Issuer or the Guarantor to the holders of Securities not less than 15 days preceding such subsequent record date. The term “record date” as used with
respect to any interest payment date (except a date for payment of defaulted interest) shall mean the date specified as such in the terms of the Securities of any particular series, or, if no such date is so specified, if such interest payment date
is the first day of a calendar month, the 15th day of the next preceding calendar month or, if such interest payment date is the 15th day of a calendar month, the first day of such calendar month, in either case whether or not such record date is a
Business Day. 
 Section 2.08. Registration, Transfer and Exchange. The Issuer will keep or cause to be kept at each
office or agency to be maintained for the purpose as provided in Section 3.02 a register or registers in which, subject to such reasonable regulations as it may prescribe, it will register, and will register the transfer of, Securities as in
this Article provided. Such register shall be in written form in the English language or in any other form capable of being converted into such form within a reasonable time. At all reasonable times such register or registers shall be open for
inspection by the Trustee. 
 Upon due presentation for registration of transfer of any Security of any series at any such
office or agency to be maintained for the purpose as provided in Section 3.02, the Issuer shall execute and the Trustee shall authenticate and deliver in the name of the transferee or transferees a new Security or Securities of the same series
in authorized denominations for a like aggregate principal amount. 

  
 9 

 Any Security or Securities of any series may be exchanged for a Security or Securities of
the same series in other authorized denominations, in an equal aggregate principal amount. Securities of any series to be exchanged shall be surrendered at any office or agency to be maintained by the Issuer for the purpose as provided in
Section 3.02, and the Issuer shall execute and the Trustee shall authenticate and deliver in exchange therefor the Security or Securities of the same series which the Securityholder making the exchange shall be entitled to receive, bearing
numbers not contemporaneously outstanding. 
 All Securities presented for registration of transfer, exchange, redemption or
payment shall (if so required by the Issuer or the Trustee) be duly endorsed by, or be accompanied by a written instrument or instruments of transfer in form satisfactory to the Issuer and the Trustee duly executed by, the holder or his attorney
duly authorized in writing. 
 The Issuer may require payment of a sum sufficient to cover any tax or other governmental charge
that may be imposed in connection with any exchange or registration of transfer of Securities. No service charge shall be made for any such transaction. 
 The Issuer shall not be required to exchange or register a transfer of (a) any Securities of any series for a period of 15 days next preceding the first mailing of notice of redemption of Securities
of such series to be redeemed, (b) any Securities selected, called or being called for redemption except, in the case of any Security where notice has been given that such Security is to be redeemed in part, the portion thereof not so to be
redeemed, or (c) any Securities of any series between a record date and the next succeeding payment date. 
 All Securities
issued upon any transfer or exchange of Securities shall be valid obligations of the Issuer, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Securities surrendered upon such transfer or exchange. 

The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed
under this Indenture or under applicable law with respect to any transfer of any interest in any Security (including any transfers between or among Depositary Participants or beneficial owners of interests in any Registered 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, this Indenture, and to examine the same to determine substantial compliance
as to form with the express requirements hereof. 
 Neither the Trustee nor any agent shall have any responsibility for any
actions taken or not taken by the Depositary. 
 Section 2.09. Mutilated, Defaced, Destroyed, Lost and Stolen Securities.
In case any temporary or definitive Security shall become mutilated, defaced or be destroyed, lost or stolen, the Issuer in its discretion may execute, and upon the written request of any officer of the Issuer, the Trustee shall authenticate and
deliver, a new Security of the same series, bearing a number not contemporaneously outstanding, in exchange and substitution for the mutilated or defaced Security, or in lieu of and substitution for the Security so destroyed, lost or stolen. In
every case the applicant for a substitute Security shall furnish to the Issuer, the Guarantor and the Trustee and any agent of the Issuer, the Guarantor or the Trustee such security or indemnity as may be required by them to indemnify and defend and
to save each of them harmless and, in every case of destruction, loss or theft, evidence to their 

  
 10 

 
satisfaction of the destruction, loss or theft of such Security and of the ownership thereof in the case of mutilation or defacement shall surrender the Security to the Trustee or such agent.

 Upon the issuance of any substitute Security, the Issuer 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 or its agent) connected therewith. In case any Security which has matured or is about to mature or has been
called for redemption in full shall become mutilated or defaced or be destroyed, lost or stolen, the Issuer may instead of issuing a substitute Security, pay or authorize the payment of the same (without surrender thereof except in the case of a
mutilated or defaced Security), if the applicant for such payment shall furnish to the Issuer, the Guarantor and the Trustee and any agent of the Issuer, the Guarantor or the Trustee such security or indemnity as any of them may require to save each
of them harmless, and, in every case of destruction, loss or theft. The applicant shall also furnish to the Issuer, the Guarantor and the Trustee and any agent of the Issuer, the Guarantor or the Trustee evidence to their satisfaction of the
destruction, loss or theft of such Security and of the ownership thereof. 
 Every substitute Security of any series issued
pursuant to the provisions of this section by virtue of the fact that any such Security is destroyed, lost or stolen shall constitute an additional contractual obligation of the Issuer and the Guarantor, whether or not the destroyed, lost or stolen
Security shall be at any time enforceable by anyone and shall be entitled to all the benefits of (but shall be subject to all the limitations of rights set forth in) this Indenture equally and proportionately with any and all other Securities of
such series duly authenticated and delivered hereunder. All Securities shall be held and owned upon the express condition that, to the extent permitted by law, the foregoing provisions are exclusive with respect to the replacement or payment of
mutilated, defaced or destroyed, lost or stolen Securities and shall preclude any and all other rights or remedies notwithstanding any law or statute existing or hereafter enacted to the contrary with respect to the replacement or payment of
negotiable instruments or other securities without their surrender. 
 Section 2.10. Cancellation of Securities. All
Securities surrendered for payment, redemption, registration of transfer or exchange, or for credit against any payment in respect of a sinking or analogous fund, if surrendered to the Issuer or any agent of the Issuer or the Trustee, shall be
delivered to the Trustee for cancellation or, if surrendered to the Trustee, shall be cancelled by it; and no Securities shall be issued in lieu thereof except as expressly permitted by any of the provisions of this Indenture. The Trustee shall
dispose of cancelled Securities held by it in accordance with its procedures for the disposition of cancelled Securities and deliver a certificate of disposition to the Issuer upon request. If the Issuer shall acquire any of the Securities, such
acquisition shall not operate as a redemption or satisfaction of the indebtedness represented by such Securities unless and until the same are delivered to the Trustee for cancellation. 

Section 2.11. Temporary Securities. Pending the preparation of definitive Securities for any series, the Issuer may execute and
the Trustee shall authenticate and deliver temporary Securities for such series (printed, lithographed, typewritten or otherwise reproduced, in each case in form satisfactory to the Trustee). Temporary Securities of any series shall be issuable as
registered Securities without coupons, of any authorized denomination, and substantially in the form of the definitive Securities of such series but with such omissions, insertions and variations as may be appropriate for temporary Securities, all
as may be determined by the Issuer with the concurrence of the Trustee. Temporary Securities may contain such reference to any provisions of this Indenture as may be appropriate. Every temporary Security shall be executed by the Issuer and be
authenticated by the Trustee upon the same conditions and in substantially the same manner, and with like effect, as the definitive Securities. Without unreasonable delay the Issuer shall execute and shall furnish definitive Securities of such
series and thereupon temporary Securities of such series may be surrendered in 

  
 11 

 
exchange therefor without charge at each office or agency to be maintained by the Issuer for that purpose pursuant to Section 3.02, and the Trustee shall authenticate and deliver in exchange
for such temporary Securities of such series a like aggregate principal amount of definitive Securities of the same series of authorized denominations. Until so exchanged, the temporary Securities of any series shall be entitled to the same benefits
under this Indenture as definitive Securities of such series unless otherwise established pursuant to Section 2.03. 

Section 2.12. CUSIP Numbers. The Issuer in issuing the Securities may use “CUSIP” numbers (if then generally in use),
and, if so, the Trustee shall use “CUSIP” numbers in notices of redemption and other notices to the Holders as a convenience to Holders; provided, that any such notice may state that no representation is made as to the correctness of such
numbers either as printed on the Securities or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption shall not be affected by any defect
in or omission of such numbers. The Issuer will promptly notify the Trustee in writing of any change in the “CUSIP” numbers. 
 Section 2.13. Registered Global Securities. None of the Issuer, the Guarantor, the Trustee or any Agent shall have any responsibility or obligation to any beneficial owner of an interest in a
Registered Global Security, any members of, or a participant in, the Depositary (“Agent Members”) or other Person with respect to the accuracy of the records of the Depositary or its nominee or any participant or Agent Member thereof, with
respect to any ownership interest in a Registered Global Security or with respect to the delivery to any participant, Agent Member, beneficial owner or other Person (other than the Depositary) of any notice or the payment of any amount or delivery
of any Registered Global Security (or other security or property) under or with respect to such Registered Global Securities. All notices and communications to be given to the Holders and all payments to be made to Holders in respect of the
Registered Global Securities shall be given or made only to or upon the order of the registered Holders. The rights of beneficial owners in any Registered Global Security shall be exercised only through the Depositary subject to the applicable rules
and procedures of the Depositary. The Issuer, the Guarantor, the Trustee and each Agent may rely and shall be fully protected in relying upon information furnished by the Depositary with respect to its Agent Members, participants and any beneficial
owners. 
 ARTICLE 3 
 COVENANTS OF THE ISSUER, THE GUARANTOR AND THE TRUSTEE 
 Section 3.01. Payment
of Principal and Interest. The Issuer covenants and agrees for the benefit of each series of Securities that it will duly and punctually pay or cause to be paid the principal of, and interest on, each of the Securities of such series (together
with any additional amounts payable pursuant to the terms of such Securities) at the place or places, at the respective times and in the manner provided in such Securities. Subject to any other provisions that may be established pursuant to
Section 2.03, the interest on Securities (together with any additional amounts payable pursuant to the terms of such Securities) shall be payable only to or upon the written order of the Holders thereof and, at the option of the Issuer, may be
paid by wire transfer or by mailing checks for such interest payable to or upon the written order of such Holders at their last addresses as they appear on the registry books of the Issuer. 

Whenever in this Indenture there is mentioned, in any context, the payment of the principal of or any premium, interest or any other
amounts on, or in respect of, any Security of any series or the net proceeds received on the sale or exchange of any Security of any series, such mention shall be deemed to include mention of the payment of additional amounts provided by the terms
of such series 

  
 12 

 
established hereby or pursuant hereto 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 provision hereof shall not be construed as excluding the payment of additional amounts in those provisions hereof where such express mention is not made. 

Section 3.02. Offices for Payments, etc. So long as any of the Securities remain outstanding, the Issuer will maintain in the
Borough of Manhattan, The City of New York, the following for each series: an office or agency (a) where the Securities may be presented for payment, (b) where the Securities may be presented for registration of transfer and for exchange
as in this Indenture or any supplemental indenture provided and (c) where notices and demands to or upon the Issuer in respect of the Securities or of this Indenture may be served. The Issuer will give to the Trustee written notice of the
location of any such office or agency and of any change of location thereof. Unless otherwise specified in accordance with Section 2.03, the Issuer hereby initially designates the Corporate Trust Office of the Trustee, as the office to be
maintained by it for each such purpose. In case the Issuer shall fail to so designate or maintain any such office or agency or shall fail to give such notice of the location or of any change in the location thereof, presentations and demands may be
made and notices may be served at the Corporate Trust Office. 
 The Issuer may from time to time designate one or more
additional offices or agencies where the Securities of a series may be presented for payment, where the Securities of that series may be presented for exchange as provided in this Indenture and pursuant to Section 2.03 and where the Securities
of that series may be presented for registration of transfer as provided in this Indenture, and the Issuer may from time to time rescind any such designation, as the Issuer may deem desirable or expedient; provided, however, that no such designation
or rescission shall in any manner relieve the Issuer of its obligation to maintain the agencies provided for in this Section. The Issuer will give to the Trustee prompt written notice of any such designation or rescission thereof. 

Section 3.03. Appointment to Fill a Vacancy in Office of Trustee. The Issuer, whenever necessary to avoid or fill a vacancy in the
office of Trustee, will appoint, in the manner provided in Section 5.09, a Trustee, so that there shall at all times be a Trustee with respect to each series of Securities hereunder. 

Section 3.04. Paying Agents. Whenever the Issuer shall appoint a paying agent other than the Trustee with respect to the
Securities of any series, it will cause such paying agent to execute and deliver to the Trustee an instrument in which such agent shall agree with the Trustee, subject to the provisions of this Section, 

(a) that it will hold all sums received by it as such agent for the payment of the principal of or interest on the Securities of such
series (whether such sums have been paid to it by the Issuer, the Guarantor or by any other obligor on the Securities of such series) in trust for the benefit of the holders of the Securities of such series or of the Trustee, 

(b) that it will give the Trustee notice of any failure by the Issuer (or by the Guarantor or any other obligor on the Securities of such
series) to make any payment of the principal of or interest on the Securities of such series when the same shall be due and payable, and 
 (c) that it will pay any such sums so held in trust by it to the Trustee upon the Trustee’s written request at any time during the continuance of the failure referred to in clause 3.04(b) above.

  
 13 

 The Issuer will, on the Business Day prior to each due date of the principal of or interest
on the Securities of such series, deposit with the paying agent a sum in immediately available funds in United States dollars sufficient to pay such principal or interest so becoming due, and (unless such paying agent is the Trustee) the Issuer will
promptly notify the Trustee of any failure to take such action. 
 If the Issuer shall act as its own paying agent with respect
to the Securities of any Series, it will, on or before each due date of the principal of or interest on the Securities of such series, set aside, segregate and hold in trust for the benefit of the holders of the Securities of such series a sum
sufficient to pay such principal or interest so becoming due. The Issuer will promptly notify the Trustee of any failure to take such action. 
 Anything in this section to the contrary notwithstanding, the Issuer may at any time, for the purpose of obtaining a satisfaction and discharge with respect to one or more or all series of Securities
hereunder, or for any other reason, pay or cause to be paid to the Trustee all sums held in trust for any such series by the Issuer or any paying agent hereunder, as required by this Section, such sums to be held by the Trustee upon the trusts
herein contained. 
 Anything in this section to the contrary notwithstanding, the agreement to hold sums in trust as provided
in this section is subject to the provisions of Sections 9.03 and 9.04. 
 For the avoidance of doubt, any paying agent
hereunder shall comply with applicable backup withholding tax and information reporting requirements under the U.S. Internal Revenue Code of 1986, as amended, and the U.S. Treasury Regulations promulgated thereunder with respect to payments made
under the Securities of any series (including, to the extent required, the collection of Internal Revenue Service Forms W-8 and W-9 and the filing of U.S. Internal Revenue Service Forms 1099 and 1096). 

Section 3.05. Certificates of the Issuer and the Guarantor. The Issuer and the Guarantor will each furnish to the Trustee within
120 days after the end of each fiscal year of the Issuer or the Guarantor, as the case may be, commencing on December 31, 2011, an Officers’ Certificate of the Issuer or the Guarantor, as the case may be, as to the signers’ knowledge
of the Issuer’s or the Guarantor’s compliance with all conditions and covenants under the Indenture (such compliance to be determined without regard to any period of grace or requirement of notice provided under the Indenture). In the
event an Officer of the Issuer comes to have actual knowledge of an Event of Default or an event which, with notice or the lapse of time or both, would constitute an Event of Default, regardless of the date, the Issuer shall deliver an
Officers’ Certificate to the Trustee specifying such Default and the nature and status thereof. 
 Section 3.06.
Securityholders Lists. If and so long as the Trustee shall not be the Security registrar for the Securities of any series, the Issuer will furnish or cause to be furnished to the Trustee a list in such form as the Trustee may reasonably
require of the names and addresses of the holders of the Securities of such series pursuant to Section 312 of the Trust Indenture Act of 1939 (a) semi-annually not more than 15 days after each record date for the payment of interest on
such Securities, as hereinabove specified, as of such record date and on dates to be determined pursuant to Section 2.03 for non-interest bearing securities in each year, and (b) at such other times as the Trustee may request in writing,
within 30 days after receipt by the Issuer of any such request as of a date not more than 15 days prior to the time such information is furnished. 
 Section 3.07. Reports by the Issuer. Each of the Issuer and the Guarantor covenants to file with the Trustee, within 15 days after the Issuer or the Guarantor, as the case may be, is required to
file the same with the Commission, copies of the annual reports and of the information, 

  
 14 

 
documents, and other reports that the Issuer or the Guarantor may be required to file with the Commission pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934.
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 Issuer’s or the Guarantor’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates or Guarantor’s
Officers’ Certificates, as applicable). 
 Section 3.08. Reports by the Trustee. Any Trustee’s report required
under Section 313(a) of the Trust Indenture Act of 1939 shall be transmitted on or before July 15 in each year following the date hereof, so long as any Securities are outstanding hereunder, and shall be dated as of a date convenient to
the Trustee no more than 60 nor less than 45 days prior thereto. 
 Section 3.09. Calculation of Original Issue Discount.
The Issuer shall prepare and provide to the Trustee on a timely basis any form required to be submitted by the Trustee on behalf of the Issuer with the Internal Revenue Service and the Holders of Securities relating to original issue discount,
including, without limitation, Form 1099-0ID or any successor form. 
 ARTICLE 4 

REMEDIES OF THE TRUSTEE AND 
 SECURITYHOLDERS ON EVENT OF DEFAULT

Acceleration of Maturity, Waiver of Default. Unless otherwise established in accordance with Section 2.03 or by any applicable supplemental indenture, “Event of Default” with respect to Securities of any series wherever used
herein means each one of the following events which shall have occurred and be continuing (whatever the reason for such Event of Default and 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 the
payment of premium or principal in respect of the Securities; 
 (b) default for more than 30 days in the payment of interest in

 15 

 
property, or ordering the winding up or liquidation of its affairs, and the continuance of any such decree or order for relief or any such other decree or order unstayed and in effect for a
period of 60 consecutive days; or 
 (e) the commencement by the Issuer or the Guarantor of a voluntary case or proceeding under
any applicable U.S. federal or state bankruptcy, insolvency, reorganization or other similar law or of any other case or proceeding to be adjudicated a bankrupt or insolvent, or the consent by the Issuer to the entry of a decree or order for relief

its property, or the making by the Issuer or the Guarantor of an assignment for the benefit of creditors, or the admission by the Issuer or the Guarantor in writing of its inability to pay its debts generally as they become due, or the taking of
corporate action by the Issuer or the Guarantor expressly in furtherance of any such action; or 
 (f) any other Event of Default
provided in the supplemental indenture or resolution of the Board under which such series of Securities is issued or in the form of Security for such series. 
 Unless otherwise set forth in any applicable supplemental indenture, if an Event of Default described in clauses 4.01(a), 4.01(b), 4.01(c), or 4.01(f) above (if the Event of Default under clauses 4.01(c)
or 4.01(f) is with respect to less than all series of Securities then Outstanding) occurs and is continuing, then, and in each and every such case, except for any series the principal of which shall have already become due and payable, either the
Trustee or the holders of not less than 25% in aggregate principal amount of the Securities of all series affected thereby then Outstanding hereunder (treated as one class) by notice in writing to the Issuer and the Guarantor (and to the Trustee if
given by Securityholders), may declare the entire principal (or, if the Securities of any such affected series are Original Issue Discount Securities, such portion of the principal amount as may be specified in the terms of such series) of all
Securities of such affected series and the interest accrued thereon, if any, to be due and payable immediately, and upon any such declaration the same shall become immediately due and payable. Unless otherwise set forth in any applicable
supplemental indenture, if an Event of Default described in clauses 4.01(c) or 4.01(f) (if the Event of Default under clauses 4.01(c) or 4.01(f) is with respect to all series of Securities at the time Outstanding) occurs and is continuing, then and
in each and every such case, unless the principal of all the Securities shall have already become due and payable, either the Trustee or the holders of not less than 25% in aggregate principal amount of all the then Outstanding Securities hereunder
(treated as one class) for which any applicable supplemental indenture does not prevent acceleration under the relevant circumstances, by notice in writing to the Issuer and the Guarantor (and to the Trustee if given by Securityholders), may declare
the entire principal (or, if any Securities are Original Issue Discount Securities, such portion of the principal as may be specified in the terms thereof) of all the Securities then Outstanding and interest accrued thereon, if any, to be due and
payable immediately, and upon any such declaration the same shall become immediately due and payable. Unless otherwise set forth in any applicable supplemental indenture, if an Event of Default described in clauses 4.01(d) or 4.01(e) occurs and is
continuing, then the principal and accrued and unpaid interest, and premium if any, with respect to any Securities then Outstanding shall ipso facto become and be immediately due and payable without any declaration or other act on the part of
the Trustee or any Holder. 

  
 16 

 The foregoing provisions, however, are subject to the condition that if, at any time after
the principal (or, if the Securities are Original Issue Discount Securities, such portion of the principal as may be specified in the terms thereof) of the Securities of any series (or of all the Securities, as the case may be) shall have been so
declared due and payable, and before any judgment or decree for the payment of the moneys due shall have been obtained or entered as hereinafter provided, the Issuer or the Guarantor shall pay or shall deposit with the Trustee a sum sufficient to
pay all matured installments of interest upon all the Securities of such series (or of all the Securities, as the case may be) and the principal of any and all Securities of such series (or of all the Securities, as the case may be) which shall have
become due otherwise than by acceleration (with interest upon such principal and, to the extent that payment of such interest is enforceable under applicable law, on overdue installments of interest at the same rate as the rate of interest or Yield
to Maturity (in the case of Original Issue Discount Securities) specified in the Securities of such series (or at the respective rates of interest or Yields to Maturity of all the Securities, as the case may be) to the date of such payment or
deposit) and such 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
negligence or bad faith, and if any and all Events of Default under the Indenture, other than the non-payment of the principal of Securities which shall have become due by acceleration, shall have been cured, waived or otherwise remedied as provided
herein, then and in every such case the holders of a majority in aggregate principal amount of all the Securities of each such series (or of all the Securities, as the case may be) then Outstanding (in each case treated as one class), by written
notice to the Issuer, the Guarantor and the Trustee, may waive all defaults with respect to each such series (or with respect to all the Securities, as the case may be) and rescind and annul such declaration and its consequences, but no such waiver
or rescission and annulment shall extend to or shall affect any subsequent default or shall impair any right consequent thereon. 
 For all purposes under this Indenture, if a portion of the principal of any Original Issue Discount Securities shall have been accelerated and declared due and payable pursuant to the provisions hereof,
then, from and after such declaration, unless such declaration has been rescinded and annulled, the principal amount of such Original Issue Discount Securities shall be deemed, for all purposes hereunder, to be such portion of the principal thereof
as shall be due and payable as a result of such acceleration, and payment of such portion of the principal thereof as shall be due and payable as a result of such acceleration, together with interest, if any, thereon and all other amounts owing
thereunder, shall constitute payment in full of such Original Issue Discount Securities. 
 Section 4.02. Collection of
Indebtedness by Trustee; Trustee May Prove Debt. Each of the Issuer and the Guarantor covenants that (a) in case default shall be made in the payment of any installment of interest on any of the Securities of any series when such interest
shall have become due and payable, and such default shall have continued for a period of 30 days or (b) in case default shall be made in the payment of all or any part of the principal of any of the Securities of any series when the same shall
have become due and payable, whether upon maturity of the Securities of such series or upon any redemption or by declaration or otherwise, then upon demand of the Trustee, the Issuer or the Guarantor, as the case may be, will pay to the Trustee for
the benefit of the Holders of the Securities of such series the whole amount that then shall have become due and payable on all Securities of such series for principal or interest, as the case may be (with interest to the date of such payment upon
the overdue principal and, to the extent that payment of such interest is enforceable under applicable law, on overdue installments of interest at the same rate as the rate of interest or Yield to Maturity (in the case of Original Issue Discount
Securities) specified in the Securities of such series); and in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including reasonable compensation to the Trustee and each predecessor
Trustee, their respective agents, attorneys and counsel, and any expenses and liabilities incurred, and all advances made, by the Trustee and each predecessor Trustee except as a result of its negligence or bad faith. 

  
 17 

 Until such demand is made by the Trustee, the Issuer may pay the principal of and interest
on the Securities of any series to the registered Holders, whether or not the principal of and interest on the Securities of such series be overdue. 
 In case the Issuer or the Guarantor shall fail forthwith to pay such amounts upon such demand, the Trustee, in its own name and as trustee of an express trust, shall be entitled and empowered to institute
any action or proceedings at law or in equity for the collection of the sums so due and unpaid, and may prosecute any such action or proceedings to judgment or final decree, and may enforce any such judgment or final decree against the Issuer or the
Guarantor or other obligor upon such Securities and collect in the manner provided by law out of the property of the Issuer or the Guarantor or other obligor upon such Securities, wherever situated, the moneys adjudged or decreed to be payable.

 In case there shall be pending proceedings relative to the Issuer, the Guarantor or any other obligor upon the Securities
under Title 11 of the United States Code or any other applicable federal or state bankruptcy, insolvency or other similar law, or in case a receiver, assignee or trustee in bankruptcy or reorganization, liquidator, sequestrator or similar official
shall have been appointed for or taken possession of the Issuer or the Guarantor or its property or such other obligor, or in case of any other comparable judicial proceedings relative to the Issuer, the Guarantor or other obligor upon the
Securities of any series, or to the creditors or property of the Issuer, the Guarantor or such other obligor, the Trustee, irrespective of whether the principal of any Securities shall then be due and payable as therein expressed or by declaration
or otherwise and irrespective of whether the Trustee shall have made any demand pursuant to the provisions of this Section, shall be entitled and empowered, by intervention in such proceedings or otherwise: 

(a) to file and prove a claim or claims for the whole amount of principal and interest (or, if the Securities of any series are Original
Issue Discount Securities, such portion of the principal amount as may be specified in the terms of such series) owing and unpaid in respect of the Securities of any series, 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 reasonable compensation to the Trustee and each predecessor Trustee, and their respective agents, attorneys and counsel, and for reimbursement of all expenses and liabilities
incurred, and all advances made, by the Trustee and each predecessor Trustee, except as a result of negligence or bad faith) and of the Securityholders allowed in any judicial proceedings relative to the Issuer, the Guarantor or other obligor upon
the Securities of any series, or to the creditors or property of the Issuer, the Guarantor or such other obligor, 
 (b) unless
prohibited by applicable law and regulations, to vote on behalf of the holders of the Securities of any series in any election of a trustee or a standby trustee in arrangement, reorganization, liquidation or other bankruptcy or insolvency
proceedings or person performing similar functions in comparable proceedings, and 
 (c) to collect and receive any moneys or
other property payable or deliverable on any such claims, and to distribute all amounts received with respect to the claims of the Securityholders and of the Trustee on their behalf; and any trustee, receiver, or liquidator, custodian or other
similar official is hereby authorized by each of the Securityholders to make payments to the Trustee, and, in the event that the Trustee shall consent to the making of payments directly to the Securityholders, to pay to the Trustee such amounts as
shall be sufficient to cover reasonable compensation to the Trustee, each predecessor Trustee and their respective agents, attorneys and counsel, and all other expenses and liabilities incurred, and all advances made, by the Trustee and each
predecessor Trustee except as a result of negligence or bad faith. 

  
 18 

 Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to
or vote for or accept or adopt on behalf of any Securityholder any plan or reorganization, arrangement, adjustment or composition affecting the Securities of any series or the rights of any Holder thereof, or to authorize the Trustee to vote in
respect of the claim of any Securityholder in any such proceeding except, as aforesaid, to vote for the election of a trustee in bankruptcy or similar person. 
 All rights of action and of asserting claims under this Indenture, or under any of the Securities, may be enforced by the Trustee without the possession of any of the Securities or the production thereof
on any trial or other proceedings relative thereto, and any such action or proceedings instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment, subject to the payment of the expenses,
disbursements and compensation of the Trustee, each predecessor Trustee and their respective agents and attorneys, shall be for the ratable benefit of the holders of the Securities in respect of which such action was taken. 

In any proceedings brought by the Trustee (and also any proceedings involving the interpretation of any provision of this Indenture to
which the Trustee shall be a party) the Trustee shall be held to represent all the holders of the Securities in respect to which such action was taken, and it shall not be necessary to make any holders of such Securities parties to any such
proceedings. 
 Section 4.03. Application of Proceeds. Any moneys collected by the Trustee pursuant to this Article in
respect of any series shall be applied in the following order at the date or dates fixed by the Trustee and, in case of the distribution of such moneys on account of principal or interest, upon presentation of the several Securities in respect of
which monies have been collected and stamping (or otherwise noting) thereon the payment, or issuing Securities of such series in reduced principal amounts in exchange for the presented Securities of like series if only partially paid, or upon
surrender thereof if fully paid: 
 FIRST: To the payment of costs and expenses applicable to such series in respect of which
monies have been collected, including reasonable compensation to the Trustee and each predecessor Trustee and their respective agents and attorneys and of all expenses and liabilities incurred, and all advances made, by the Trustee and each
predecessor Trustee except as a result of negligence or bad faith; 
 SECOND: In case the principal of the Securities of such
series in respect of which moneys have been collected shall not have become and be then due and payable, to the payment of interest on the Securities of such series in default in the order of the maturity of the installments of such interest, with
interest (to the extent that such interest has been collected by the Trustee) upon the overdue installments of interest at the same rate as the rate of interest or Yield to Maturity (in the case of Original Issue Discount Securities) specified in
such Securities, such payments to be made ratably to the persons entitled thereto, without discrimination or preference; 

THIRD: In case the principal of the Securities of such series in respect of which moneys have been collected shall have become and shall
be then due and payable, to the payment of the whole amount then owing and unpaid upon all the Securities of such series for principal and interest, with interest upon the overdue principal, and (to the extent that such interest has been collected
by the Trustee) upon overdue installments of interest at the same rate as the rate of interest or Yield to Maturity (in the case of Original Issue Discount Securities) specified in the Securities of such series; and in case such moneys shall be
insufficient to pay in full the whole amount so due and unpaid upon the Securities of such series, then to the payment of such principal and interest or Yield to Maturity, without preference or priority of principal over interest or Yield to
Maturity, or of interest or Yield to Maturity over principal, or of any installment of interest over any other installment of interest, or of any Security of such series over any other Security of such series, ratably to the aggregate of such
principal and accrued and unpaid interest or Yield to Maturity; and 

  
 19 

 FOURTH: To the payment of the remainder, if any, to the Issuer or any other person lawfully
entitled thereto. 
 Section 4.04. Suits for Enforcement. In case an Event of Default has occurred, has not been waived
and is continuing, the Trustee may in its discretion proceed to protect and enforce the rights vested in it by this Indenture by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any of such
rights, either at law or in equity or in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement contained in this Indenture or in aid of the exercise of any power granted in this Indenture or to enforce any other
legal or equitable right vested in the Trustee by this Indenture or by law. 
 Section 4.05. Restoration of Rights on
Abandonment of Proceeding. In case the Trustee shall have proceeded to enforce any right under this Indenture and such proceedings shall have been discontinued or abandoned for any reason, or shall have been determined adversely to the Trustee,
then and in every such case the Issuer and the Trustee shall be restored respectively to their former positions and rights hereunder, and all rights, remedies and powers of the Issuer, the Trustee and the Securityholders shall continue as though no
such proceedings had been taken. 
 Section 4.06. Limitations on Suits by Securityholder. No holder of any Security of
any series shall have any right by virtue or by availing of any provision of this Indenture to institute any action or proceeding at law or in equity or in bankruptcy or otherwise upon or under or with respect to this Indenture, or for the
appointment of a trustee, receiver, liquidator, custodian or other similar official or for any other remedy hereunder, unless such Holder previously shall have given to the Trustee written notice of default and of the continuance thereof, as
hereinbefore provided, and unless also the Holders of not less than 25% in aggregate principal amount of the Securities of each affected series then Outstanding (treated as a single class) shall have made written request upon the Trustee to
institute such action or proceedings in its own name as trustee hereunder and shall have offered to the Trustee such reasonable indemnity as it may require against the costs, expenses and liabilities to be incurred therein or thereby and the Trustee
for 60 days after its receipt of such notice, request and offer of indemnity shall have failed to institute any such action or proceeding and no direction inconsistent with such written request shall have been given to the Trustee pursuant to
Section 4.09; it being understood and intended, and being expressly covenanted by the taker and Holder of every Security with every other taker and Holder and the Trustee, that no one or more Holders of Securities of any series shall have any
right in any manner whatever by virtue or by availing of any provision of this Indenture to affect, disturb or prejudice the rights of any other such Holder of Securities, or to obtain or seek to obtain priority over or preference to any other such
Holder or to enforce any right under this Indenture, except in the manner herein provided and for the equal, ratable and common benefit of all Holders of Securities of the applicable series. For the protection and enforcement of the provisions of
this Section, each and every Securityholder and the Trustee shall be entitled to such relief as can be given either at law or in equity. 
 Section 4.07. Unconditional Right of Securityholders to Institute Certain Suits. Notwithstanding any other provision in this Indenture and any provision of any Security, the right of any Holder of
any Security to receive payment of the principal of and interest on such Security on or after the respective due dates expressed in such Security, or to institute suit for the enforcement of any such payment on or after such respective dates, shall
not be impaired or affected without the consent of such Holder. 

  
 20 

 Section 4.08. Powers and Remedies Cumulative; Delay or Omission Not Waiver of
Default. Except as provided in Section 4.06, no right or remedy herein conferred upon or reserved to the Trustee or to the Securityholders 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. 
 No delay or omission of the
Trustee or of any Securityholder to exercise any right or power accruing upon any Event of Default occurring and continuing as aforesaid shall impair any such right or power or shall be construed to be a waiver of any such Event of Default or an
acquiescence therein; and, subject to Section 4.06, every power and remedy given by this Indenture or by law to the Trustee or to the Securityholders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee
or by the Securityholders. 
 Section 4.09. Control by Securityholders. The Holders of a majority in aggregate principal
amount of the Securities of each series affected (with all such series voting as a single class) at the time Outstanding shall have the right to direct the time, method, and place of conducting any proceeding for any remedy available to the Trustee,
or exercising any trust or power conferred on the Trustee with respect to the Securities of such series by this Indenture; provided that such direction shall not be otherwise than in accordance with law and the provisions of this Indenture and
provided further that (subject to the provisions of Section 5.01) the Trustee shall have the right to decline to follow any such direction if the Trustee shall determine that the action or proceeding so directed may not lawfully be taken or if
the Trustee in good faith shall determine that the action or proceedings so directed would involve the Trustee in personal liability or if the Trustee in good faith shall so determine that the actions or forebearances specified in or pursuant to
such direction would be unduly prejudicial to the interests of Holders of the Securities of all series so affected not joining in the giving of said direction, it being understood that (subject to Section 5.01) the Trustee shall have no duty to
ascertain whether or not such actions or forebearances are unduly prejudicial to such Holders. 
 Nothing in this Indenture
shall impair the right of the Trustee in its discretion to take any action deemed proper by the Trustee and which is not inconsistent with such direction or directions by Securityholders. 

Section 4.10. Waiver of Past Defaults. Prior to the acceleration of the maturity of any Securities as provided in
Section 4.01, the Holders of a majority in aggregate principal amount of the Securities of all series at the time Outstanding with respect to which an Event of Default shall have occurred and be continuing (voting as a single class) may on
behalf of the Holders of all such Securities waive any past default or Event of Default described in Section 4.01 and its consequences, except a default in respect of a covenant or provision hereof which cannot be modified or amended without
the consent of the Holder of each Security affected. In the case of any such waiver, the Issuer, the Guarantor, the Trustee and the Holders of all such Securities shall be restored to their former positions and rights hereunder, respectively; but no
such waiver shall extend to any subsequent or other default or impair any right consequent thereon. 
 Upon any such waiver,
such default shall cease to exist and be deemed to have been cured and not to have occurred, and any Event of Default arising therefrom shall be deemed to have been cured, and not to have occurred for every purpose of this Indenture; but no such
waiver shall extend to any subsequent or other default or Event of Default or impair any right consequent thereon. 

  
 21 

 Section 4.11. Trustee to Give Notice of Default, But May Withhold in Certain
Circumstances. The Trustee shall give to the Securityholders of any series, as the names and addresses of such Holders appear on the registry books, notice by mail of all defaults known to the Trustee which have occurred with respect to such
series, such notice to be transmitted within 90 days after the occurrence thereof, unless such defaults shall have been cured before the giving of such notice (the term “default” or “defaults” for the purposes of this section
being hereby defined to mean any event or condition which is, or with notice or lapse of time or both would become, an Event of Default); provided that, except in the case of default in the payment of the principal of or interest on any of the
Securities of such series, or in the payment of any sinking or purchase fund installment with respect to the 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 or trustees and/or Responsible Officers of the Trustee in good faith determines that the withholding of such notice is in the interests of the Securityholders of such series. 

Section 4.12. Right of Court to Require Filing of Undertaking to Pay 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,
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 Securityholder or group of Securityholders of any series holding in the aggregate more than 10% in aggregate principal amount of the Securities of such series, or, in the case of any suit relating to or arising under clauses
4.01(c) or 4.01(f) (if the suit relates to Securities of more than one but less than all series), 10% in aggregate principal amount of Securities Outstanding affected thereby, or in the case of any suit relating to or arising under clauses 4.01(c)
or 4.01(f) (if the suit relates to all the Securities then Outstanding), 4.01(d) or 4.01(e), 10% in aggregate principal amount of all Securities Outstanding, or to any suit instituted by any Securityholder for the enforcement of the payment of the
principal of or interest on any Security on or after the due date expressed in such Security. 
 ARTICLE 5 

CONCERNING THE TRUSTEE 
 Section 5.01. Duties and Responsibilities of the Trustee; During Default; Prior to Default. With respect to the Holders of any series of Securities issued hereunder, the Trustee, prior to the
occurrence of an Event of Default with respect to the Securities of a particular series and after the curing or waiving of all Events of Default which may have occurred with respect to such series, undertakes to perform such duties and only such
duties as are specifically set forth in this Indenture. In case an Event of Default with respect to the Securities of a series has occurred (which has not been cured or waived) the Trustee shall exercise with respect to such series of Securities
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 his or her own affairs. 

No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent
failure to act or its own willful misconduct, except that 

  
 22 

 (a) prior to the occurrence of an Event of Default with respect to the Securities of any
series and after the curing or waiving of all such Events of Default with respect to such series which may have occurred: 
 (i) the duties and obligations of the Trustee with respect to the Securities of any Series shall be determined solely by the express provisions of this Indenture, and the Trustee shall not be liable
except for the performance of such duties and obligations as are specifically set forth in this Indenture, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and 

(ii) in the absence of bad faith on the part of the Trustee, the Trustee may conclusively rely, as to the truth of the
statements and the correctness of the opinions expressed therein, upon any statements, certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but in the case of any such statements, 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 (but need not
confirm or investigate the accuracy of mathematical calculations or other facts stated therein); 
 (b) the Trustee shall not be
liable for any error of judgment made in good faith by a Responsible Officer or Responsible Officers of the Trustee, unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts; and 

(c) the Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the
direction of the holders pursuant to Section 4.09 relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture.

 None of the provisions contained in this Indenture shall require the Trustee to expend or risk its own funds or otherwise
incur personal financial liability in the performance of any of its duties or in the exercise of any of its rights or powers, if there shall be reasonable ground for believing that the repayment of such funds or adequate indemnity against such
liability is not reasonably assured to it. 
 The provisions of this Section 5.01 are in furtherance of and subject to
Sections 315 and 316 of the Trust Indenture Act of 1939. 
 Section 5.02. Certain Rights of the Trustee. In furtherance
of and subject to the Trust Indenture Act of 1939, and subject to Section 5.01: 
 (a) the Trustee may conclusively rely and
shall be protected in acting or refraining from acting upon any resolution, Officers’ Certificate, Guarantor’s Officers’ Certificate or any other certificate, statement, instrument, opinion, report, notice, request, consent, order,
bond, debenture, note, coupon, security or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties; 
 (b) any request, direction, order or demand of the Issuer or the Guarantor mentioned herein shall be sufficiently evidenced by an Officers’ Certificate or a Guarantor’s Officers’
Certificate, as the case may be, (unless other evidence in respect thereof be herein specifically prescribed); and any resolution of the Board or of the Guarantor’s Board of Directors may be evidenced to the Trustee by a copy thereof certified
by the secretary or an assistant secretary of the Issuer or the Guarantor, as the case may be; 

  
 23 

 (c) the Trustee may consult with counsel of its selection and any advice or Opinion of
Counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted to be taken by it hereunder in good faith and in accordance with such advice or Opinion of Counsel; 

(d) the Trustee shall be under no obligation to exercise any of the trusts or powers vested in it by this Indenture at the request, order
or direction of any of the Securityholders pursuant to the provisions of this Indenture, unless such Securityholders shall have offered to the Trustee security or indemnity satisfactory to it against the costs, expenses and liabilities which might
be incurred therein or thereby; 
 (e) the Trustee shall not be liable for any action taken or omitted by it in good faith and
believed by it to be authorized or within the discretion, rights or powers conferred upon it by this Indenture; 
 (f) prior to
the occurrence of an Event of Default hereunder and after the curing or waiving of all Events of Default, the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, report, notice, request, consent, order, approval, appraisal, bond, debenture, note, coupon, security, or other paper or document unless requested in writing so to do by the holders of not less than a majority in aggregate
principal amount of the Securities of all series affected then outstanding; provided that, if the payment within a reasonable time to the Trustee of the costs, expenses or liabilities likely to be incurred by it in the making of such investigation
is, in the opinion of the Trustee, not reasonably assured to the Trustee by the security afforded to it by the terms of this Indenture, the Trustee may require indemnity satisfactory to it against such expenses or liabilities as a condition to
proceeding; the reasonable expenses of every such investigation shall be paid by the Issuer or, if paid by the Trustee or any predecessor trustee, shall be repaid by the Issuer upon demand; 

(g) the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents
or attorneys not regularly in its employ and the Trustee shall not be responsible for any misconduct or negligence on the part of any such agent or attorney appointed with due care by it hereunder; 

(h) whenever in the administration of this Indenture the Trustee shall deem it desirable that a matter be proved or established prior to
taking, suffering or omitting any action hereunder, the Trustee (unless other evidence be herein specifically prescribed) may, in the absence of bad faith on its part, conclusively rely upon an Officers’ Certificate or a Guarantor’s
Officers’ Certificate, as the case may be; 
 (i) the Trustee shall not be deemed to have notice of any Event of Default or
an event which, with notice or lapse of time or both, would constitute an Event of Default unless a Responsible Officer of the Trustee has actual knowledge thereof or unless written notice of any event which is in fact such a default is received by
the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Securities and this Indenture; 
 (j)
the rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each
agent, custodian and other Person employed to act hereunder; 

  
 24 

 (k) the Trustee may request that the Issuer or the Guarantor deliver an Officers’
Certificate or a Guarantor’s Officers’ Certificate, as the case may be, setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture, which Officers’
Certificate or Guarantor’s Officers’ Certificate, as the case may be, may be signed by any person authorized to sign an Officers’ Certificate or a Guarantor’s Officers’ Certificate, as the case may be, including any person
specified as so authorized in any such certificate previously delivered and not superseded; 
 (l) in no event shall the Trustee
be responsible or liable for special, indirect, incidental, punitive or consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of
such loss or damage and regardless of the form of action; 
 (m) in no event shall the Trustee be responsible or liable for any
failure or delay in the performance of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including, without limitation, strikes, work stoppages, accidents, acts of war or terrorism, civil or
military disturbances, nuclear or natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services; it being understood that the Trustee shall use reasonable
efforts which are consistent with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances; and 
 (n) neither the Trustee nor any Agent shall have any obligation or duty to monitor, determine or inquire as to compliance by the Issuer, the Guarantor or the Securityholders with or with respect to any
securities or tax laws (including but not limited to any United States federal or state or other securities or tax laws), or, except as specifically provided herein, obtain documentation on any transfers or exchanges of the Securities of any series.
Nothing in this provision shall be deemed to limit the Trustee’s duty to comply with any obligations it may have pursuant to applicable law. 
 Section 5.03. Trustee Not Responsible for Recitals, Disposition of Securities or Application of Proceeds Thereof. The recitals contained herein and in the Securities, except the Trustee’s
certificates of authentication, shall be taken as the statements of the Issuer or the Guarantor, as the case may be, and the Trustee assumes no responsibility for the correctness of the same. The Trustee makes no representation as to the validity or
sufficiency of this Indenture or of the Securities. The Trustee shall not be accountable for the use or application by the Issuer of any of the Securities or of the proceeds thereof. 

Section 5.04. Trustee and Agents May Hold Securities; Collections, etc. The Trustee or any agent of the Issuer, the Guarantor or
the Trustee, in its individual or any other capacity, may become the owner or pledgee of Securities with the same rights it would have if it were not the Trustee or such agent and may otherwise deal with the Issuer or the Guarantor and receive,
collect, hold and retain collections from the Issuer or the Guarantor with the same rights it would have if it were not the Trustee or such agent. 
 Section 5.05. Moneys Held by Trustee. Subject to the provisions of Section 9.04 hereof, all moneys received by the Trustee shall, until used or applied as herein provided, be held in trust for
the purposes for which they were received, but need not be segregated from other funds except to the extent required by mandatory provisions of law. Neither the Trustee nor any agent of the Issuer or the Trustee shall be under any liability for
interest on any moneys received by it hereunder. 
 Section 5.06. Compensation and Indemnification of Trustee and its Prior
Claim. The Issuer covenants and agrees to pay to the Trustee from time to time, and the Trustee shall be entitled to, compensation as the Issuer and the Trustee shall from time to time agree in writing (which shall not be

limited by any provision of law in regard to the compensation of a trustee of an express trust) and the Issuer covenants and agrees to pay or reimburse the Trustee and each predecessor Trustee
upon its request for all reasonable expenses, disbursements and advances incurred or made by or on behalf of it in accordance with any of the provisions of this Indenture (including the reasonable compensation and the expenses and disbursements of
its counsel and of all agents and other persons not regularly in its employ) except to the extent any such expense, disbursement or advance may arise from its negligence or bad faith. The Issuer also covenants to indemnify the Trustee and each
predecessor Trustee and their agents, officers, directors and employees for, and to hold each of them harmless against, any loss, liability or expense arising out of or in connection with the acceptance or administration of this Indenture or the
trusts hereunder and the performance of its duties hereunder, including the costs and expenses of defending itself against or investigating any claim of liability in the premises, except to the extent such loss liability or expense is due to the
negligence or bad faith of the Trustee or such predecessor Trustee or their respective agents, officers, directors and employees. The obligations of the Issuer under this section to compensate and indemnify the Trustee and each predecessor Trustee
and to pay or reimburse the Trustee and each predecessor Trustee for expenses, disbursements and advances shall constitute additional indebtedness hereunder and shall survive the payment in full of the Securities issued hereunder, the resignation or
removal of the Trustee, or the satisfaction and discharge of this Indenture. Such additional indebtedness shall be a senior claim to that of the Securities upon all property and funds held or collected by the Trustee as such, except funds held in
trust for the benefit of the holders of particular Securities, and the Securities are hereby subordinated to such senior claim. 

When the Trustee incurs expenses or renders services in connection with an Event of Default specified in Section 4.01(d) or
Section 4.01(e), the expenses (including the reasonable charges and expenses of its counsel) and the compensation for the services are intended to constitute expenses of administration under any applicable federal or state bankruptcy,
insolvency or other similar law. 
 Section 5.07. Right of Trustee to Rely on Officers’ Certificate, etc. Subject to
Sections 5.01 and 5.02, whenever in the administration of the trusts of this Indenture the Trustee shall deem it necessary or desirable that a matter be proved or established prior to taking or suffering or omitting any action hereunder, such matter
(unless other evidence in respect thereof be herein specifically prescribed) may, in the absence of negligence or bad faith on the part of the Trustee, be deemed to be conclusively proved and established by an Officers’ Certificate delivered to
the Trustee, and such certificate, in the absence of negligence or bad faith on the part of the Trustee, shall be full warrant to the Trustee for any action taken, suffered or omitted by it under the provisions of this Indenture upon the faith
thereof. 
 Section 5.08. Persons Eligible for Appointment as Trustee. The Trustee for each series of Securities
hereunder shall at all times be a corporation organized and doing business under the laws of the United States of America or the District of Columbia having a combined capital and surplus of at least $25,000,000, and which is eligible in accordance
with the provisions of Section 310(a) of the Trust Indenture Act of 1939. If such corporation publishes reports of condition at least annually, pursuant to law or to the requirements of a federal, state 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. 

Section 5.09. Resignation and Removal; Appointment of Successor Trustee. (a) The Trustee, or any trustee or trustees
hereafter appointed, may at any time resign with respect to one or more or all series of Securities by giving written notice of resignation to the Issuer and by mailing notice thereof by first class mail to Holders of the applicable series of
Securities at their last addresses as they shall appear on the Security register. Upon receiving such notice of resignation, the Issuer shall promptly 

  
 26 

 
appoint a successor trustee or trustees with respect to the applicable series by written instrument in duplicate, executed by authority of the Board, one copy of which instrument shall be
delivered to the resigning Trustee and one copy to the successor trustee or trustees. If no successor trustee shall have been so appointed with respect to any series and have accepted appointment within 30 days after the mailing of such notice of
resignation, the resigning trustee at the Issuer’s expense may petition any court of competent jurisdiction for the appointment of a successor trustee, or any Securityholder who has been a bona fide Holder of a Security or Securities of the
applicable series for at least six months may, subject to the provisions of Section 4.12, on behalf of himself and all others similarly situated, petition any such court for the appointment of a successor trustee. Such court may thereupon,
after such notice, if any, as it may deem proper and prescribe, appoint a successor trustee. 
 (b) In case at any time any of
the following shall occur: 
 (i) the Trustee shall fail to comply with the provisions of Section 310(b) of
the Trust Indenture Act of 1939 with respect to any series of Securities after written request therefor by the Issuer or by any Securityholder who has been a bona fide Holder of a Security or Securities of such series for at least six months; or

 (ii) the Trustee shall cease to be eligible in accordance with the provisions of Section 310(a) of the
Trust Indenture Act of 1939 and shall fail to resign after written request therefor by the Issuer or by any Securityholder; or 
 (iii) the Trustee shall become incapable of acting with respect to any series of Securities, or shall be adjudged a bankrupt or insolvent, or a receiver or liquidator of the Trustee or of its property
shall be appointed, or any public officer 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, the Issuer may remove the Trustee with respect to the applicable series of Securities and appoint a successor trustee for such series by written instrument, in duplicate, executed
by order of the Board of the Issuer, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor trustee, or, subject to Section 315(e) of the Trust Indenture Act of 1939, any Securityholder who has
been a bona fide Holder of a Security or Securities 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 removal of the Trustee and the appointment of
a successor trustee with respect to such series. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor trustee. 

(c) The Holders of a majority in aggregate principal amount of the Securities of each series at the time outstanding may at any time
remove the Trustee with respect to Securities of such series and appoint a successor trustee with respect to the Securities of such series by delivering to the Trustee so removed, to the successor trustee so appointed and to the Issuer the evidence
provided for in Section 6.01 of the action in that regard taken by the Securityholders. 
 (d) Any resignation or removal
of the Trustee with respect to any series and any appointment of a successor trustee with respect to such series pursuant to any of the provisions of this Section 5.09 shall become effective upon acceptance of appointment by the successor
trustee as provided in Section 5.10. 
 Section 5.10. Acceptance of Appointment by Successor Trustee. Any successor
trustee appointed as provided in Section 5.09 shall execute and deliver to the Issuer and to its predecessor trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal of

  
 27 

 
the predecessor trustee with respect to all or any applicable series shall become effective and such successor trustee, without any further act, deed or conveyance, shall become vested with all
rights, powers, duties and obligations with respect to such series of its predecessor hereunder, with like effect as if originally named as trustee for such series hereunder; but, nevertheless, on the written request of the Issuer or of the
successor trustee, upon payment of its charges then unpaid, the trustee ceasing to act shall, subject to Section 9.04, pay over to the successor trustee all moneys at the time held by it hereunder and shall execute and deliver an instrument
transferring to such successor trustee all such rights, powers, duties and obligations. Upon request of any such successor trustee, the Issuer shall execute any and all instruments in writing for more fully and certainly vesting in and confirming to
such successor trustee all such rights and powers. Any trustee ceasing to act shall, nevertheless, retain a prior claim upon all property or funds held or collected by such trustee to secure any amounts then due it pursuant to the provisions of
Section 5.06. 
 If a successor trustee is appointed with respect to the Securities of one or more (but not all) series,
the Issuer, the predecessor Trustee and each successor trustee with respect to the Securities of any applicable series shall execute and deliver an indenture supplemental hereto which shall contain such provisions as shall be deemed necessary or
desirable to confirm that all the rights, powers, trusts and duties of the predecessor Trustee with respect to the Securities of any series as to which the predecessor Trustee is not retiring shall continue to be vested in the predecessor Trustee,
and 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 that each such trustee shall be trustee of a trust or trusts under separate indentures. 
 Upon acceptance of appointment by any successor trustee as provided in this Section 5.10, the Issuer shall mail notice thereof by first-class mail to the Holders of Securities of any series for which
such successor trustee is acting as trustee at their last addresses as they shall appear in the Security register. If the acceptance of appointment is substantially contemporaneous with the resignation, then the notice called for by the preceding
sentence may be combined with the notice called for by Section 5.09. If the Issuer fails to mail such notice within 10 days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be mailed at
the expense of the Issuer. 
 Section 5.11. Merger, Conversion, Consolidation or Succession to Business of Trustee. 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 of the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided that such corporation shall be eligible under the provisions of Section 5.08, without the execution or filing of any
paper or any further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding. 
 In case
at the time such successor to the Trustee shall succeed to the trusts created by this Indenture any of the Securities of any series shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of
authentication of any predecessor Trustee and deliver such Securities so authenticated; and, in case at that time any of the Securities of any series shall not have been authenticated, any successor to the Trustee may authenticate such Securities
either in the name of any predecessor hereunder or in the name of the successor Trustee; and in all such cases such certificate shall have the full force which it is anywhere in the Securities of such series or in this Indenture provided that the
certificate of the Trustee shall have; provided, that the right to adopt the certificate of authentication of any predecessor Trustee or to authenticate Securities of any series in the name of any predecessor Trustee shall apply only to its
successor or successors by merger, conversion or consolidation.

 ARTICLE 6 
 CONCERNING THE SECURITYHOLDERS 
 Section 6.01. Evidence of Action Taken by
Securityholders. Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by a specified percentage in principal amount of the Securityholders of any or all series may
be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such specified percentage of Securityholders in person or by agent duly appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered to the Trustee. Proof of execution of any instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and (subject to
Sections 5.01 and 5.02) conclusive in favor of the Trustee and the Issuer, if made in the manner provided in this Article. 

Section 6.02. Proof of Execution of Instruments and of Holding of Securities; Record Date. Subject to Sections 5.01 and 5.02, the
execution of any instrument by a Securityholder or his agent or proxy may be proved in accordance with such reasonable rules and regulations as may be prescribed by the Trustee or in such manner as shall be satisfactory to the Trustee. The holding
of Securities shall be proved by the Security register or by a certificate of the registrar thereof. The Issuer may set a record date for purposes of determining the identity of holders of Securities of any series entitled to vote or consent to any
action referred to in Section 6.01, which record date may be set at any time or from time to time by notice to the Trustee, for any date or dates (in the case of any adjournment or reconsideration) not more than 60 days nor less than 5 days
prior to the proposed date of such vote or consent, and thereafter, notwithstanding any other provisions hereof, only holders of Securities of such series of record on such record date shall be entitled to so vote or give such consent or revoke such
vote or consent. 
 Section 6.03. Holders to be Treated as Owners. The Issuer, the Guarantor, the Trustee and any agent
of the Issuer, the Guarantor or the Trustee may deem and treat the person in whose name any Security shall be registered upon the Security register for such series as the absolute owner of such Security (whether or not such Security shall be overdue
and notwithstanding any notation of ownership or other writing thereon) for the purpose of receiving payment of or on account of the principal of and, subject to the provisions of this Indenture, interest on such Security and for all other purposes;
and none of the Issuer, the Guarantor, the Trustee or any agent of the Issuer, the Guarantor or the Trustee shall be affected by any notice to the contrary. All such payments so made to any such person, or upon his order, shall be valid, and, to the
extent of the sum or sums so paid, effectual to satisfy and discharge the liability for moneys payable upon any such Security. 

Section 6.04. Securities Owned by Issuer Deemed Not Outstanding. In determining whether the Holders of the requisite aggregate
principal amount of Outstanding Securities of any or all series have concurred in any direction, consent or waiver under this Indenture, Securities which are owned by the Issuer or any other obligor on the Securities with respect to which such
determination is being made or by any person directly or indirectly controlling or controlled by or under direct or indirect common control with the Issuer or any other obligor on the Securities with respect to which such determination is being made
shall be disregarded and deemed not to be Outstanding for the purpose of any such determination, except that for the purpose of determining whether the Trustee shall be protected in relying on any such direction, consent or waiver only Securities
which a Responsible Officer of the Trustee actually knows are so owned shall be so disregarded. Securities so owned which have been pledged in good faith may be regarded as Outstanding if the pledgee establishes to the satisfaction of the Trustee
the pledgee’s right so to act with respect to such Securities and that the pledgee is not the Issuer or any other obligor upon the Securities or any person directly or indirectly controlling or controlled by or

  
 29 

 
under direct or indirect common control with the Issuer or any other obligor on the Securities. In case of a dispute as to such right, the advice of counsel shall be full protection in respect of
any decision made by the Trustee in accordance with such advice. Upon request of the Trustee, the Issuer shall furnish to the Trustee promptly an Officers’ Certificate listing and identifying all Securities, if any, known by the Issuer to be
owned or held by or for the account of any of the above-described persons; and, subject to Sections 5.01 and 5.02, the Trustee shall be entitled to accept such Officers’ Certificate as conclusive evidence of the facts therein set forth and of
the fact that all Securities not listed therein are Outstanding for the purpose of any such determination. 
 Section 6.05.
Right of Revocation of Action Taken. At any time prior to (but not after) the evidencing to the Trustee, as provided in Section 6.01, of the taking of any action by the Holders of the percentage in aggregate principal amount of the
Securities of any or all series, as the case may be, specified in this Indenture in connection with such action, any Holder of a Security the serial number of which is shown by the evidence to be included among the serial numbers of the Securities
the Holders of which have consented to such action may, by filing written notice at the Corporate Trust Office and upon proof of holding as provided in this Article, revoke such action so far as concerns such Security. Except as aforesaid any such
action taken by the Holder of any Security shall be conclusive and binding upon such Holder and upon all future Holders and owners of such Security and of any Securities issued in exchange or substitution therefor or on registration of transfer
thereof, irrespective of whether or not any notation in regard thereto is made upon any such Security. Any action taken by the Holders of the percentage in aggregate principal amount of the Securities of any or all series, as the case may be,
specified in this Indenture in connection with such action shall be conclusively binding upon the Issuer, the Trustee and the Holders of all the Securities affected by such action. 

ARTICLE 7 

SUPPLEMENTAL INDENTURES 
 Section 7.01. Supplemental Indentures without Consent of Securityholders. The Issuer, when authorized by a resolution of its Board (which resolutions may provide general authorization for such
action and may provide that the specific terms of such action may be determined by officers of the Issuer authorized thereby), and the Guarantor, when authorized by a resolution of the Guarantor’s Board of Directors, and the Trustee may from
time to time and at any time enter into an indenture or indentures supplemental hereto for one or more of the following purposes: 
 (a) to convey, transfer, assign, mortgage or pledge to the Trustee as security for the Securities of one or more series any property or assets; 

(b) to evidence the succession of another legal entity to the Issuer or the Guarantor, as the case may be, or successive successions, and
the assumption by the successor legal entity of the covenants, agreements and obligations of the Issuer or the Guarantor, as the case may be, pursuant to Article 8; 
 (c) to add to the covenants of the Issuer or the Guarantor such further covenants, restrictions, conditions or provisions as the Issuer, the Guarantor and the Trustee shall consider to be for the
protection of the Holders of Securities, and to make the occurrence, or the occurrence and continuance, of a default in any such additional covenants, restrictions, conditions or provisions an Event of Default permitting the enforcement of all or
any of the several remedies provided in this Indenture as herein set forth; provided, that in respect of any such additional covenant, restriction, condition or provision such supplemental indenture may provide for a particular period of grace after
default (which period may be shorter or longer than that allowed in the case of other defaults) or may provide for an 

  
 30 

 
immediate enforcement upon such an Event of Default or may limit the remedies available to the Trustee upon such an Event of Default or may limit the right of the Holders of a majority in
aggregate principal amount of the Securities of such series to waive such an Event of Default; 
 (d) to cure any ambiguity or
to correct or supplement any provision contained herein or in any supplemental indenture which may be defective or inconsistent with any other provision contained herein or in any supplemental indenture; or to make such other provisions in regard to
matters or questions arising under this Indenture or under any supplemental indenture as the Issuer or the Guarantor may deem necessary or desirable and which shall not adversely affect the interests of the Holders of the Securities in any material
respect; 
 (e) to establish the form or terms of Securities of any series as permitted by Sections 2.01 and 2.03; and

 (f) to evidence the assumption by the Guarantor of all of the rights and obligations of the Issuer hereunder with respect to a
series of Securities and under the Securities of such series and the release of the Issuer from its liabilities hereunder and under such Securities as obligor on the Securities of such series, all as provided in Section 12.06 hereof.

 The Trustee is hereby authorized to join with the Issuer and the Guarantor in the execution of any such supplemental
indenture, to make any further appropriate agreements and stipulations which may be therein contained and to accept the conveyance, transfer, assignment, mortgage or pledge of any property thereunder, but the Trustee 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. 
 Any supplemental indenture authorized by the provisions of this section may be executed without the consent of the Holders of any of the Securities at the time outstanding, notwithstanding any of the
provisions of Section 7.02. 
 Section 7.02. Supplemental Indentures with Consent of Securityholders. With the
consent (evidenced as provided in Article 6) of the Holders of not less than a majority in aggregate principal amount of the Securities at the time Outstanding of all series affected by such supplemental indenture (voting as one class), the Issuer,
when authorized by a resolution of its Board (which resolutions may provide general authorization for such action and may provide that the specific terms of such action may be determined by officers of the Issuer authorized thereby), and the
Guarantor, when authorized by a resolution of the Guarantor’s Board of Directors, and the Trustee may, from time to time and at any time, enter into an indenture or indentures supplemental hereto for the purpose of adding any provisions to or
changing in any manner or eliminating any of the provisions of this Indenture or of any supplemental indenture or of modifying in any manner the rights of the Holders of the Securities of each such series; provided, that no such supplemental
indenture shall (a) (i) extend the final maturity of any Security, (ii) reduce the principal amount thereof, (iii) reduce the rate or extend the time of payment of interest thereon, (iv) reduce any amount payable on
redemption thereof, (v) make the principal thereof (including any amount in respect of original issue discount), or interest thereon payable in any coin or currency other than that provided in the Securities or in accordance with the terms
thereof, (vi) modify or amend any provisions for converting any currency into any other currency as provided in the Securities or in accordance with the terms thereof, (vii) reduce the amount of the principal of an Original Issue Discount
Security that would be due and payable upon an acceleration of the maturity thereof pursuant to Section 4.01 or the amount thereof provable in bankruptcy pursuant to Section 4.02, (viii) modify or amend any provisions relating to the
conversion or exchange of the Securities for securities of the Issuer or the Guarantor or of other entities or other property (or the cash value thereof), including the determination of 

  
 31 

 
the amount of securities or other property (or cash) into which the Securities shall be converted or exchanged, other than as provided in the antidilution provisions or other similar adjustment
provisions of the Securities or otherwise in accordance with the terms thereof, or (ix) alter the provisions of Section 10.11 or Section 10.13 or impair or affect the right of any Securityholder to institute suit for the payment
thereof or, if the Securities provide therefor, any right of repayment at the option of the Securityholder, in each case without the consent of the Holder of each Security so affected, or (b) reduce the aforesaid percentage of Securities of any
series, the consent of the Holders of which is required for any such supplemental indenture, without the consent of the Holders of each Security so affected. 
 A supplemental indenture which changes or eliminates any covenant or other provision of this Indenture which has expressly been included solely for the benefit of one or more particular series of
Securities, or which modifies the rights of holders of Securities of such series, with respect to such covenant or provision, shall be deemed not to affect the rights under this Indenture of the holders of Securities of any other series. 

Upon the request of the Issuer, accompanied by a copy of a resolution of the Board (which resolutions may provide general authorization
for such action and may provide that the specific terms of such action may be determined by officers of the Issuer authorized thereby) certified by the secretary or an assistant secretary of the Issuer authorizing the execution of any such
supplemental indenture, and upon the filing with the Trustee of evidence of the consent of Securityholders as aforesaid and other documents, if any, required by Section 6.01, the Trustee shall join with the Issuer and the Guarantor in the
execution of such supplemental indenture unless such supplemental indenture affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated
to, enter into such supplemental indenture. 
 It shall not be necessary for the consent of the Securityholders under this
section to approve the particular form of any proposed supplemental indenture, but it shall be sufficient if such consent shall approve the substance thereof. 
 Promptly after the execution by the Issuer, the Guarantor and the Trustee of any supplemental indenture pursuant to the provisions of this Section, the Trustee shall give notice thereof by (a) first
class mail to the Holders of Securities of each series affected thereby at their addresses as they shall appear on the registry books of the Issuer or (b) by any other means set forth in such supplemental indenture, setting forth in general
terms the substance of such supplemental indenture. Any failure of the Trustee to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such supplemental indenture. 

Section 7.03. Effect of Supplemental Indenture. Upon the execution of any supplemental indenture pursuant to the provisions
hereof, this Indenture shall be and be deemed to be modified and amended in accordance therewith and the respective rights, limitations of rights, obligations, duties and immunities under this Indenture of the Trustee, the Issuer, the Guarantor and
the Holders of Securities of each series affected thereby shall thereafter be determined, exercised and enforced hereunder subject in all respects to such modifications and amendments, and all the terms and conditions of any such supplemental
indenture shall be and be deemed to be part of the terms and conditions of this Indenture for any and all purposes. 
 Section
7.04. Documents to Be Given to Trustee. In executing, or accepting the additional trusts created by, any supplemental indenture permitted by this Article or the modification thereby of the trusts created by this Indenture, the Trustee shall
receive, and shall be fully protected in relying upon, an Officers’ Certificate and an Opinion of Counsel stating that the execution of such supplemental indenture is authorized or permitted by this Indenture. The Trustee may, but shall not be
obligated to, enter into any such supplemental indenture which adversely affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise. 

  
 32 

 Section 7.05. Notation on Securities in Respect of Supplemental Indentures.
Securities of any series authenticated and delivered after the execution of any supplemental indenture pursuant to the provisions of this Article may bear a notation in form approved by the Trustee for such series as to any matter provided for by
such supplemental indenture or as to any action taken by Securityholders. If the Issuer or the Trustee shall so determine, new Securities of any series so modified as to conform, in the opinion of the Trustee and the Board, to any modification of
this Indenture contained in any such supplemental indenture may be prepared by the Issuer, authenticated by the Trustee and delivered in exchange for the Securities of such series then Outstanding. 

ARTICLE 8 

CONSOLIDATION, MERGER, SALE OR CONVEYANCE 
 Section 8.01. Issuer May Consolidate, etc., on Certain Terms. The Issuer covenants that it will not merge or consolidate with any other Person or sell or convey all or substantially all of its
assets to any Person, unless (i) either the Issuer shall be the continuing legal entity, or the successor legal entity or the Person which acquires by sale or conveyance substantially all the assets of the Issuer (if other than the Issuer)
shall expressly assume the due and punctual payment of the principal of and interest on all the Securities, according to their tenor, and the due and punctual performance and observance of all of the covenants and conditions of this Indenture to be
performed or observed by the Issuer, by supplemental indenture satisfactory to the Trustee, executed and delivered to the Trustee by such successor legal entity, and (ii) the Issuer or such successor legal entity, as the case may be, shall not,
immediately after such merger or consolidation, or such sale or conveyance, be in default in the performance of any such covenant or condition. 
 Section 8.02. Successor Substituted. In case of any such consolidation, merger, sale or conveyance, and following such an assumption by the successor legal entity, all in the manner described in
section 8.01, such successor legal entity shall succeed to and be substituted for the Issuer, with the same effect as if it had been named herein. Such successor legal entity may cause to be signed, and may issue either in its own name or in the
name of the Issuer prior to such succession any or all of the Securities issuable hereunder which theretofore shall not have been signed by the Issuer and delivered to the Trustee; and, upon the order of such successor legal entity instead of the
Issuer and subject to all the terms, conditions and limitations in this Indenture prescribed, the Trustee shall authenticate and shall deliver any Securities which previously shall have been signed and delivered by the officers of the Issuer to the
Trustee for authentication, and any Securities which such successor legal entity thereafter shall cause to be signed and delivered to the Trustee for that purpose. All of the Securities so issued shall in all respects have the same legal rank and
benefit under this Indenture as the Securities theretofore or thereafter issued in accordance with the terms of this Indenture as though all of such Securities had been issued at the date of the execution hereof. Any required changes in phrasing and
form (but not in substance) may be made in the Securities thereafter to be issued as may be appropriate. 
 In the event of such
assumption following any sale or conveyance in accordance with section 8.01 and this section 8.02 (other than a conveyance by way of lease) the Issuer (including any successor legal entity that has been further substituted in accordance with section
8.01 and this section 8.02) shall be discharged from all obligations and covenants under this Indenture and the Securities and may be liquidated and dissolved. 

  
 33 

 Section 8.03. Guarantor May Consolidate, etc., on Certain Terms. The Guarantor
covenants that it will not merge or consolidate with any other Person or sell, lease or convey all or substantially all of its assets to any other Person, unless (i) either the Guarantor shall be the continuing legal entity, or the successor
legal entity or the Person which acquires by sale, lease or conveyance substantially all the assets of the Guarantor (if other than the Guarantor) shall expressly assume the due and punctual payment of the principal of and interest on all the
Securities and the due and punctual performance and observance of all of the covenants and conditions of this Indenture to be performed or observed by the Guarantor, by supplemental indenture satisfactory to the Trustee, executed and delivered to
the Trustee by such successor legal entity, and (ii) the Guarantor, such Person or such successor legal entity, as the case may be, shall not, immediately after such merger or consolidation, or such sale, lease or conveyance, be in default in
the performance of any such covenant or condition. 
 Section 8.04. Successor Legal Entity Substituted for the Guarantor.
In case of any such consolidation, merger, sale, lease or conveyance, and following such an assumption by the successor legal entity, all in the manner described in section 8.03, such successor legal entity shall succeed to and be substituted for
the Guarantor with the same effect as if it had been named herein and any required changes in phrasing and form (but not in substance) may be made in the Securities thereafter to be issued as may be appropriate. 

In the event of such assumption following any sale or conveyance in accordance with section 8.03 and this section 8.04 (other than a
conveyance by way of lease) the Guarantor (including any successor legal entity that has been further substituted in accordance with section 8.03 and this section 8.04) shall be discharged from all obligations and covenants under this Indenture and
the Securities and may be liquidated and dissolved. 
 Section 8.05. Opinion of Counsel to Trustee. The Trustee, subject
to the provisions of Sections 5.01 and 5.02, shall receive an Opinion of Counsel, prepared in accordance with Section 10.05, as conclusive evidence that any such consolidation, merger, sale, lease or conveyance, and any such assumption, and any
such liquidation or dissolution, complies with the applicable provisions of this Indenture. 
 ARTICLE 9 

SATISFACTION AND DISCHARGE OF INDENTURE; UNCLAIMED MONEYS 
 Section 9.01. Satisfaction and Discharge of Indenture. (a) If at any time (i) the Issuer or the Guarantor shall have paid or caused to be paid the principal of and interest on all the
Securities of any series outstanding hereunder (other than Securities of such series which have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 2.09) as and when the same shall have become due and
payable, or (ii) the Issuer or the Guarantor shall have delivered to the Trustee for cancellation all Securities of any series theretofore authenticated (other than any Securities of such series which shall have been destroyed, lost or stolen
and which shall have been replaced or paid as provided in Section 2.09) or (iii) (A) all the securities of such series not theretofore delivered to the Trustee for cancellation shall have become due and payable, or are by their terms
to become due and payable within one year or are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption, and (B) the Issuer or the Guarantor shall have irrevocably
deposited or caused to be deposited with the Trustee as trust funds the entire amount in cash (other than moneys repaid by the Trustee or any paying agent to the Issuer in accordance with Section 9.04) in the case of any series of Securities
the payments on which may only be made in United States dollars, direct obligations of the United States of America, backed by its full faith and credit (“U.S. Government Obligations”), maturing as to principal and interest at such times
and in such amounts as will 

  
 34 

 
insure the availability of cash, or a combination thereof, sufficient to pay at maturity or upon redemption all Securities of such series (other than any Securities of such series which shall
have been destroyed, lost or stolen and which shall have been replaced or paid as provided in Section 2.09) not theretofore delivered to the Trustee for cancellation, including principal and interest due or to become due on or prior to such
date of maturity as the case may be, and if, in any such case, the Issuer or the Guarantor shall also pay or cause to be paid all other sums payable hereunder by the Issuer or the Guarantor with respect to Securities of such series, then this
Indenture shall cease to be of further effect with respect to Securities of such series (except as to (i) rights of registration of transfer and exchange of securities of such series, and the Issuer’s right of optional redemption, if any,
(ii) substitution of mutilated, defaced, destroyed, lost or stolen Securities, (iii) rights of holders to receive payments of principal thereof and interest thereon upon the original stated due date therefor (but no upon acceleration), and
remaining rights of the holders to receive mandatory sinking fund payments, if any, (iv) the rights, obligations, indemnities and immunities of the Trustee hereunder and (v) the rights of the Securityholders of such series as beneficiaries
hereof with respect to the property so deposited with the Trustee payable to all or any of them), and the Trustee, on demand of the Issuer or the Guarantor accompanied by an Officers’ Certificate (or Guarantor’s Officer’s Certificate
respectively) and an Opinion of Counsel and at the cost and expense of the Issuer, shall execute proper instruments acknowledging such satisfaction of and discharging this Indenture with respect to such series; provided, that the rights of Holders
of the Securities to receive amounts in respect of principal of and interest on the Securities held by them shall not be delayed longer than required by then-applicable mandatory rules or policies of any securities exchange upon which the Securities
are listed. The Issuer agrees to reimburse the Trustee for any costs or expenses thereafter reasonably and properly incurred and to compensate the Trustee for any services thereafter reasonably and properly rendered by the Trustee in connection with
this Indenture or the Securities of such series. 
 (b) The following provisions shall apply to the Securities of each series
unless specifically otherwise provided in a Board Resolution, Officers’ Certificate or indenture supplemental hereto provided pursuant to Section 2.03. In addition to discharge of the Indenture pursuant to the next preceding paragraph, in
the case of any series of Securities the exact amounts (including the currency of payment) of principal of and interest due on which can be determined at the time of making the deposit referred to in clause 9.01(b)(i) below, the Issuer and the
Guarantor shall be deemed to have paid and discharged the entire indebtedness on all the Securities of such a series on the 91st day after the date of the deposit referred to in clause 9.01(b)(i) below, and the provisions of this Indenture with
respect to the Securities of such series thereto shall no longer be in effect (except as to (1) rights of registration of transfer and exchange of Securities of such series and the Issuer’s right of optional redemption, if any,
(2) substitution of mutilated, defaced, destroyed, lost or stolen Securities, (3) rights of Holders of Securities to receive payments of principal thereof and interest thereon, upon the original stated due dates therefor (but not upon
acceleration), and remaining rights of the Holders to receive mandatory sinking fund payments, if any, (4) the rights, obligations, duties, indemnities and immunities of the Trustee hereunder, (5) the rights of the Holders of Securities of
such series as beneficiaries hereof with respect to the property so deposited with the Trustee payable to all or any of them and (6) the obligations of the Issuer under Section 3.02) and the Trustee, at the expense of the Issuer or the
Guarantor, shall at the Issuer’s or the Guarantor’s request, execute proper instruments acknowledging the same, if 
 (i) with reference to this provision the Issuer or the Guarantor has irrevocably deposited or caused to be irrevocably deposited with the Trustee as trust funds in trust specifically pledged as security
for, and dedicated solely to, the benefit of the Holders of the Securities of such series (A) cash in an amount, or (B) in the case of any series of Securities the payments on which may only be made in Dollars, U.S. Government Obligations,
maturing as to principal and interest at such times and in such amounts as will insure the availability of cash 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 

  
 35 

 
Trustee, to pay (1) the principal and interest on all Securities of such series and Coupons appertaining thereto on each date that such principal or interest is due and payable and
(2) any mandatory sinking fund payments on the dates on which such payments are due and payable in accordance with the terms of the Indenture and the Securities of such series; 

(ii) such deposit will not result in a breach or violation of, or constitute a default under, any agreement or instrument
to which the Issuer is a party or by which it is bound; 
 (iii) the Issuer or the Guarantor has delivered to
the Trustee an Opinion of Counsel based on the fact that (x) the Issuer has received from, or there has been published by, the Internal Revenue Service a ruling or (y) since the date hereof, there has been a change in the applicable
federal income tax law, in either case to the effect that, and such opinion shall confirm that, the Holders of the Securities of such series and Coupons appertaining thereto will not recognize income, gain or loss for federal income tax purposes as
a result of such deposit, defeasance and discharge and will be subject to federal income tax on the same amount and in the same manner and at the same times, as would have been the case if such deposit, defeasance and discharge had not occurred; and

 (iv) the Issuer or the Guarantor has delivered to the Trustee an Officers’ Certificate or
Guarantor’s Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for relating to the defeasance contemplated by this provision have been complied with. 

(c) Each of the Issuer and the Guarantor shall be released from its obligations under Section 8.01 with respect to the Securities of
any Series, Outstanding, and under any guarantee in respect thereof, on and after the date the conditions set forth below are satisfied (hereinafter, “covenant defeasance”). For this purpose, such covenant defeasance means that, with
respect to the Outstanding Securities of any Series, and under a guarantee in respect thereof, the Issuer and the Guarantor may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in such
Sections, whether directly or indirectly by reason of any reference elsewhere herein to such Sections or by reason of any reference in such Sections to any other provision herein or in any other document and such omission to comply shall not
constitute an Event of Default under Section 4.01, but the remainder of this Indenture and such Securities and Coupons and the Guarantee shall be unaffected thereby. The following shall be the conditions to application of this subsection
(c) of this Section 9.01: 
 (i) The Issuer or the Guarantor has irrevocably deposited or caused to be
deposited with the Trustee 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 the Securities of such series, (A) cash in an
amount, or (B) in the case of any series of Securities the payments on which may only be made in Dollars, U.S. Government Obligations maturing as to principal and interest at such times and in such amounts as will insure the availability of
cash 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 (1) the principal and interest on
all Securities of such series and Coupons appertaining thereto and (2) any mandatory sinking fund payments on the day on which such payments are due and payable in accordance with the terms of the Indenture and the Securities of such series.

 (ii) No Event of Default or event which with notice or lapse of time or both would become an Event of Default
with respect to the Securities shall have occurred and be continuing on the date of such deposit, after giving effect thereto. 

  
 36 

 (iii) Such covenant defeasance shall not cause the Trustee to have a
conflicting interest for purposes of the Trust Indenture Act of 1939 with respect to any securities of the Issuer. 
 (iv) Such covenant defeasance shall not result in a breach or violation of, or constitute a default under, this Indenture or any other agreement or instrument to which the Issuer or the Guarantor is a
party or by which either of them is bound. 
 (v) Such covenant defeasance shall not cause any Securities then
listed on any registered national securities exchange under the Securities Exchange Act of 1934, as amended, to be delisted.

that the Holders of the Securities of such series 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 such covenant defeasance had not occurred. 
 (vii) The Issuer
or the Guarantor shall have delivered to the Trustee an Officers’ Certificate or Guarantor’s Officers’ Certificate, as the case may be, and an Opinion of Counsel, each stating that all conditions precedent provided for relating to the
covenant defeasance contemplated by this provision have been complied with. 
 Section 9.02. Application by Trustee of Funds
Deposited for Payment of Securities. Subject to Section 9.04 and any subordination provisions applicable to the Securities; all moneys deposited with the Trustee pursuant to Section 9.01 shall be held in trust and applied by it to the
payment, either directly or through any paying agent (including the Issuer acting as its own paying agent), to the Holders of the particular Securities of such series for the payment or redemption of which such moneys have been deposited with the
Trustee, of all sums due and to become due thereon for principal and interest; but such money need not be segregated from other funds except to the extent required by law. 
 Section 9.03. Repayment of Moneys Held by Paying Agent. In connection with the satisfaction and discharge of this Indenture with respect to Securities of any series, all moneys then held by any
paying agent under the provisions of this Indenture with respect to such series of Securities shall, upon written demand of the Issuer, be repaid to it or paid to the Trustee and thereupon such paying agent shall be released from all further
liability with respect to such moneys. 
 Section 9.04. Return of Moneys Held by Trustee and Paying Agent Unclaimed for Two
Years. Any moneys deposited with or paid to the Trustee or any paying agent for the payment of the principal of or interest on any Security of any series and not applied but remaining unclaimed for two years after the date upon which such
principal or interest shall have become due and payable, shall, upon the written request of the Issuer and unless otherwise required by mandatory provisions of applicable escheat or abandoned or unclaimed property law, be repaid to the Issuer by the
Trustee for such series or such paying agent, and the Holder of the Security of such series shall, unless otherwise required by mandatory provisions of applicable escheat or abandoned or unclaimed property laws, thereafter look only to the Issuer
for any payment which such Holder may be entitled to collect, and all liability of the Trustee or any paying agent with respect to such moneys shall thereupon cease. 

  
 37 

 The Issuer shall pay and indemnify the Trustee against any tax, fee or other charge imposed
on or assessed against the U.S. Government Obligations deposited pursuant to Section 9.01 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
Outstanding Securities.

such covenants and provisions being for the sole benefit of the parties hereto and their successors and of the Holders of the Securities.

 Any notice, direction, request or demand by the Issuer, the Guarantor or any Securityholder to or upon the Trustee shall be deemed to have been sufficiently given or made, for all purposes, if delivered
in person or mailed by first-class mail to the Trustee at 101 Barclay Street, Floor 4E, New York, NY 10286, Attention: Corporate Trust Administration – Global Finance Unit. 

The Trustee agrees to accept and act upon instructions or directions pursuant to this Indenture sent by unsecured e-mail, facsimile
transmission or other similar unsecured electronic methods. If the party elects to give the Trustee e-mail or facsimile instructions (or instructions by a similar electronic method) and the Trustee in its discretion elects to act upon such
instructions, the Trustee’s understanding of such instructions shall be deemed controlling. The Trustee shall not be liable for any losses, costs or expenses arising directly or indirectly from the Trustee’s reliance upon and compliance
with such instructions notwithstanding such instructions conflict or are inconsistent with a subsequent written instruction. Each other party agrees to assume all risks arising out of the use of such electronic methods to submit instructions and
directions to the Trustee, including without limitation the risk of the Trustee acting on unauthorized instructions, and the risk or interception and misuse by third parties. 
 Where this Indenture provides for notice to Holders, such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to

  
 39 

 
each Holder entitled thereto, at his last address as it appears in the Security register. In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any
defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. 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. 
 In case, by reason of the suspension of or irregularities in regular mail service,
it shall be impracticable to mail notice to the Issuer, the Guarantor or Securityholders 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 a sufficient giving of such notice. 
 Notwithstanding anything to the contrary contained herein,
as long as the Securities are in the form of a Registered Global Security, notice to the Holders may be made electronically in accordance with procedures of the Depositary. 
 Section 10.05. Officers’ Certificates and Opinions of Counsel; Statements to be Contained Therein. Upon any application or demand by the Issuer or the Guarantor to the Trustee to take any
action under any of the provisions of this Indenture, the Issuer or the Guarantor, as the case may be, shall furnish to the Trustee an Officers’ Certificate or Guarantor’s Officers’ Certificate, as the case may be, stating that all
conditions precedent provided for in this Indenture relating to the proposed action have been complied with and an Opinion of Counsel stating that in the opinion of such counsel all such conditions precedent have been complied with. 

Each certificate or opinion provided for in this Indenture and delivered to the Trustee with respect to compliance with a condition or
covenant provided for in this Indenture shall include (a) a statement that the person making such certificate or opinion has read such covenant or condition, (b) a brief statement as to the nature and scope of the examination or
investigation upon which the statements or opinions contained in such certificate or opinion are based, (c) a statement that, in the opinion of such person, he has made such examination or investigation as is necessary to enable him to express
an informed opinion as to whether or not such covenant or condition has been complied with and (d) a statement as to whether or not, in the opinion of such person, such condition or covenant has been complied with. 

Any certificate, statement or opinion of an officer of the Issuer or the Guarantor may be based, insofar as it relates to legal matters,
upon a certificate or opinion of or representations by counsel, unless such officer knows that the certificate or opinion or representations with respect to the matters upon which his certificate, statement or opinion may be based as aforesaid are
erroneous, or in the exercise of reasonable care should know that the same are erroneous. Any certificate, statement or opinion of counsel may be based, insofar as it relates to factual matters, information with respect to which is in the possession
of the Issuer or the Guarantor, as the case may be, upon the certificate, statement or opinion of or representations by an officer of officers of the Issuer or the Guarantor, as the case may be, unless such counsel knows that the certificate,
statement or opinion or representations with respect to the matters upon which his certificate, statement or opinion may be based as aforesaid are erroneous, or in the exercise of reasonable care should know that the same are erroneous. 

Any certificate, statement or opinion of an officer of the Issuer or the Guarantor or of counsel may be based, insofar as it relates to
accounting matters, upon a certificate or opinion of or representations by an accountant or firm of accountants in the employ of the Issuer, unless such officer or counsel, as the case may be, knows that the certificate or opinion or representations
with respect to the 

  
 40 

 
accounting matters upon which his certificate, statement or opinion may be based as aforesaid are erroneous, or in the exercise of reasonable care should know that the same are erroneous.

 Any certificate or opinion of any independent firm of public accountants filed with the Trustee shall contain a statement
that such firm is independent. 
 Section 10.06. Payments Due on Saturdays, Sundays and Holidays. If the date of maturity
of interest on or principal of the Securities of any series or the date fixed for redemption or repayment of any such Security shall not be a Business Day, then payment of interest or principal 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 date of maturity or the date fixed for redemption, and no interest shall accrue for the period after such date. 

Section 10.07. Conflict of any Provision of Indenture with Trust Indenture Act of 1939. If and to the extent that any provision of
this Indenture limits, qualifies or conflicts with another provision included in this Indenture by operation of Sections 310 to 317, inclusive, of the Trust Indenture Act of 1939 (an “incorporated provision”), such incorporated provision
shall control. 
 Section 10.08. New York Law to Govern. This Indenture and each Security shall be deemed to be a
contract under the laws of the State of New York, and for all purposes shall be construed in accordance with the laws of such State. 
 Section 10.09. Counterparts. This Indenture may be executed in any number of counterparts, each of which shall be an original; but such counterparts shall together constitute but one and the same
instrument. 
 Section 10.10. Effect of Headings. The Article and Section headings herein and the Table of Contents are
for convenience only and shall not affect the construction hereof. 
 Section 10.11. Securities in a Non-U.S. Currency.
Unless otherwise specified in an Officers’ Certificate delivered pursuant to Section 2.03 of this Indenture with respect to a particular series of Securities, whenever for purposes of this Indenture any action may be taken by the Holders
of a specified percentage in aggregate principal amount of Securities of all series or all series affected by a particular action at the time Outstanding and, at such time, there are Outstanding Securities of any series which are denominated in a
coin or currency other than Dollars, then the principal amount of Securities of such series which shall be deemed to be Outstanding for the purpose of taking such action shall be that amount of Dollars that could be obtained for such amount at the
Market Exchange Rate. For purposes of this Section 10.11, Market Exchange Rate shall mean the noon Dollar buying rate in New York City for cable transfers of that currency as published by the Federal Reserve Bank of New York. If such Market
Exchange Rate is not available for any reason with respect to such currency, the Issuer shall use, in good faith and its reasonable discretion and without liability on its part, such quotation of the Federal Reserve Bank of New York as of the most
recent available date, or quotations from one or more major banks in The City of New York or in the country of issue of the currency in question, or such other quotations as the Issuer shall in its commercially reasonable judgment deem appropriate.
The provisions of this paragraph shall apply in determining the equivalent principal amount in respect of Securities of a series denominated in a currency other than Dollars in connection with any action taken by Holders of Securities pursuant to
the terms of this Indenture. 
 All decisions and determinations of the Issuer regarding the Market Exchange Rate or any
alternative determination provided for in the preceding paragraph shall be in its commercially 

  
 41 

 
reasonable judgment and shall, in the absence of manifest error, be conclusive to the extent permitted by law for all purposes and irrevocably binding upon the Issuer and all Holders. 

Section 10.12. Submission to Jurisdiction. Each of the Issuer and the Guarantor agrees that any legal suit, action or proceeding
arising out of or based upon this Indenture may be instituted in any federal or state court sitting in New York City, and, to the fullest extent permitted by law, waives any objection which it may now or hereafter have to the laying of venue of any
such proceeding, and irrevocably submits to the jurisdiction of such court in any suit, action or proceeding. Each of the Issuer and the Guarantor, as long as any of the Securities remain Outstanding or the parties hereto have any obligation under
this Indenture, shall have an authorized agent (the “Authorized Agent”) in the United States upon whom process may be served in any such legal action or proceeding. Service of process upon such agent and written notice of such service
mailed or delivered to it shall to the extent permitted by law be deemed in every respect effective service of process upon it in any such legal action or proceeding. The Issuer and the Guarantor each hereby appoints Teva Pharmaceuticals USA, Inc.,
1090 Horsham Road, North Wales, PA 19454, as its agent for such purposes, and covenants and agrees that service of process in any legal action or proceeding may be made upon it at such office of such agent. 

Section 10.13. Judgment Currency. Each of the Issuer and the Guarantor agrees, to the fullest extent that it may effectively do so
under applicable law, that (a) if for the purpose of obtaining judgment in any court it is necessary to convert the sum due in respect of the principal of or interest on the Securities of any series (the “Required Currency”) into a
currency in which a judgment will be rendered (the “Judgment Currency”), the rate of exchange used shall be the rate at which in accordance with normal banking procedures the Trustee could purchase in The City of New York the Required
Currency with the Judgment Currency on the day on which final unappealable judgment is entered, unless such day is not a New York Banking Day, then, to the extent permitted by applicable law, the rate of exchange used shall be the rate at which in
accordance with normal banking procedures the Trustee could purchase in The City of New York the Required Currency with the Judgment Currency on the New York Banking Day preceding the day on which final unappealable judgment is entered and
(b) its obligations under this Indenture to make payments in the Required Currency (i) shall not be discharged or satisfied by any tender, or any recovery pursuant to any judgment (whether or not entered in accordance with subsection (a)),
in any currency other than the Required Currency, except to the extent that such tender or recovery shall result in the actual receipt, by the payee, of the full amount of the Required Currency expressed to be payable in respect of such payments,
(ii) shall be enforceable as an alternative or additional cause of action for the purpose of recovering in the Required Currency the amount, if any, by which such actual receipt shall fall short of the full amount of the Required Currency so
expressed to be payable and (iii) shall not be affected by judgment being obtained for any other sum due under this Indenture. For purposes of the foregoing, “New York Banking Day” means any day except a Saturday, Sunday or a legal
holiday in The City of New York or a day on which banking institutions in The City of New York are authorized or required by law or executive order to close. 
 Section 10.14. Waiver of Jury Trial. EACH OF THE ISSUER, THE GUARANTOR AND THE TRUSTEE HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY
JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE SECURITIES OR THE TRANSACTION CONTEMPLATED HEREBY.

 ARTICLE 11 
 REDEMPTION OF SECURITIES AND SINKING FUNDS 
 Section 11.01. Applicability Of
Article. The provisions of this Article shall be applicable to the Securities of any series which are redeemable before their maturity or to any sinking fund for the retirement of Securities of a series except as otherwise specified as
contemplated by Section 2.03 for Securities of such series. 
 Section 11.02. Notice Of Redemption; Partial
Redemptions. Notice of redemption to the Holders of Securities of any series to be redeemed as a whole or in part at the option of the Issuer shall be given by mailing notice of such redemption by first class mail, postage prepaid, at least 30
days and not more than 60 days prior to the date fixed for redemption to such Holders of Securities of such series at their last addresses as they shall appear upon the registry books. Any notice which is mailed in the manner herein provided shall
be conclusively presumed to have been duly given, whether or not the Holder receives the notice. Failure to give notice by mail, or any defect in the notice to the Holder of any Security of a series designated for redemption as a whole or in part
shall not affect the validity of the proceedings for the redemption of any other Security of such series. Any such notice of redemption shall also be given to the Trustee in the manner provided in Section 10.04 hereof at least 30 days and not
more than 60 days prior to the date fixed for redemption. 
 The notice of redemption to each such Holder shall specify the
principal amount of each Security of such series held by such Holder to be redeemed, the CUSIP number (if any), the date fixed for redemption, the redemption price, the place or places of payment, that payment will be made upon presentation and
surrender of such Securities, that such redemption is pursuant to the mandatory or optional sinking fund, or both, if such be the case, that interest accrued to the date fixed for redemption will be paid as specified in such notice and that on and
after said date interest thereon or on the portions thereof to be redeemed will cease to accrue. In case any Security of a series is to be redeemed in part the notice of redemption shall state the portion of the principal amount thereof to be
redeemed and shall state that on and after the date fixed for redemption, upon surrender of such Security, a new Security or Securities of such series in principal amount equal to the unredeemed portion thereof will be issued. 

The notice of redemption of Securities of any series to be redeemed at the option of the Issuer shall be given by the Issuer or, at the
Issuer’s request delivered to the Trustee at least 5 days before the date such notice is to be given (unless a shorter period shall be acceptable to the Trustee), by the Trustee in the name and at the expense of the Issuer. 

On or before the redemption date specified in the notice of redemption given as provided in this Section, the Issuer will deposit with
the Trustee or with one or more paying agents (or, if the Issuer is acting as its own paying agent, set aside, segregate and hold in trust as provided in Section 3.04) an amount of money or other property sufficient to redeem on the redemption
date all the Securities of such series so called for redemption at the appropriate redemption price, together with accrued interest to the date fixed for redemption. If less than all the outstanding Securities of a series are to be redeemed, the
Issuer will deliver to the Trustee at least 70 days prior to the date fixed for redemption an Officers’ Certificate stating the aggregate principal amount of Securities to be redeemed. 

If less than all the Securities of a series are to be redeemed, the Trustee shall select, in such manner as it shall deem appropriate and
fair, Securities of such series to be redeemed in whole or in part. Securities may be redeemed in part in multiples equal to the minimum authorized denomination for Securities of such series or any multiple thereof. The Trustee shall promptly notify
the Issuer in writing of the Securities of such series selected for redemption and, in the case of any Securities of such series 

  
 43 

 
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 of any series 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 11.03. Payment of Securities Called for Redemption. If notice of redemption has been given as above provided, the
Securities or portions of Securities specified in such notice shall become due and payable on the date and at the place stated in such notice at the applicable redemption price, together with interest accrued to the date fixed for redemption, and on
and after said date (unless the Issuer shall default in the payment of such Securities at the redemption price, together with interest accrued to said date) interest on the Securities or portions of Securities so called for redemption shall cease to
accrue and, except as provided in Sections 5.05 and 9.04, such Securities shall cease from and after the date fixed for redemption to be entitled to any benefit or security under this Indenture, and the Holders thereof shall have no right in respect
of such Securities except the right to receive the redemption price thereof and unpaid interest to the date fixed for redemption. On presentation and surrender of such Securities at a place of payment specified in said notice, said Securities or the
specified portions thereof shall be paid and redeemed by the Issuer at the applicable redemption price, together with interest accrued thereon to the date fixed for redemption; provided that any semiannual payment of interest becoming due on the
date fixed for redemption shall be payable to the Holders of such Securities registered as such on the relevant record date subject to the terms and provisions of Sections 2.03 and 2.04 hereof. 

If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal shall, until paid or duly
provided for, bear interest from the date fixed for redemption at the rate of interest or Yield to Maturity (in the case of an Original Issue Discount Security) borne by such Security. 

Upon presentation of any Security redeemed in part only, the Issuer shall execute and the Trustee shall authenticate and deliver to or on
the order of the Holder thereof, at the expense of the Issuer, a new Security or Securities of such series, of authorized denominations, in principal amount equal to the unredeemed portion of the Security so presented. 

Section 11.04. Exclusion of Certain Securities from Eligibility for Selection for Redemption. Securities shall be excluded from
eligibility for selection for redemption if they are identified by registration and certificate number in a written statement signed by an authorized officer of the Issuer and delivered to the Trustee at least 40 days prior to the last date on which
notice of redemption may be given as being owned of record and beneficially by, and not pledged or hypothecated by either (a) the Issuer or (b) an entity specifically identified in such written statement as directly or indirectly
controlling or controlled by or under direct or indirect common control with the Issuer. 
 Section 11.05. Mandatory and
Optional Sinking Funds. The minimum amount of any sinking fund payment provided for by the terms of the 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”. The date on which a sinking fund payment is to be made is herein referred to as the “sinking fund payment
date”. 
 In lieu of making all or any part of any mandatory sinking fund payment with respect to any series of Securities
in cash, the Issuer may at its option (a) deliver to the Trustee Securities of such series theretofore purchased or otherwise acquired (except upon redemption pursuant to the mandatory sinking fund) by the Issuer or receive credit for
Securities of such series (not previously so credited) 

  
 44 

 
theretofore purchased or otherwise acquired (except as aforesaid) by the Issuer and delivered to the Trustee for cancellation pursuant to Section 2.10, (b) receive credit for optional
sinking fund payments (not previously so credited) made pursuant to this Section, or (c) receive credit for Securities of such series (not previously so credited) redeemed by the Issuer through any optional redemption provision contained in the
terms of such series. Securities so delivered or credited shall be received or credited by the Trustee at the sinking fund redemption price specified in such Securities. 
 On or before the 60th day next preceding each sinking fund payment date for any series, the Issuer will deliver to the Trustee a written statement (which need not contain the statements required by
Section 10.05) signed by an authorized officer of the Issuer (a) specifying the portion of the mandatory sinking fund payment to be satisfied by payment of cash and the portion to be satisfied by credit of Securities of such series,
(b) stating that none of the Securities of such series has theretofore been so credited, (c) stating that no defaults in the payment of interest or Events of Default with respect to such series have occurred (which have not been waived or
cured) and are continuing and (d) stating whether or not the Issuer intends to exercise its right to make an optional sinking fund payment with respect to such series and, if so, specifying the amount of such optional sinking fund payment which
the Issuer intends to pay on or before the next succeeding sinking fund payment date. Any Securities of such series to be credited and required to be delivered to the Trustee in order for the Issuer to be entitled to credit therefor as aforesaid
which have not theretofore been delivered to the Trustee shall be delivered for cancellation pursuant to Section 2.10 to the Trustee with such written statement (or reasonably promptly thereafter if acceptable to the Trustee). Such written
statement shall be irrevocable and upon its receipt by the Trustee the Issuer shall become unconditionally obligated to make all the cash payments or payments therein referred to, if any, on or before the next succeeding sinking fund payment date.
Failure of the Issuer, on or before any such 60th day, to deliver such written statement and Securities specified in this paragraph, if any, shall not constitute a default but shall constitute, on and as of such date, the irrevocable election of the
Issuer (i) that the mandatory sinking fund payment for such series due on the next succeeding sinking fund payment date shall be paid entirely in cash without the option to deliver or credit Securities of such series in respect thereof and
(ii) that the Issuer will make no optional sinking fund payment with respect to such series as provided in this Section. 

If the sinking fund payment or payments (mandatory or optional or both) to be made in cash on the next succeeding sinking fund payment
date plus any unused balance of any preceding sinking fund payments made in cash shall exceed $50,000 (or a lesser sum if the Issuer shall so request in writing to the Trustee specifying such lesser amount) with respect to the Securities of any
particular series, such cash shall be applied on the next succeeding sinking fund payment date to the redemption of Securities of such series at the sinking fund redemption price together with accrued interest to the date fixed for redemption. If
such amount shall be $50,000 or less and the Issuer makes no such request then it shall be carried over until a sum in excess of $50,000 is available. The Trustee shall select, in the manner provided in Section 11.02, for redemption on such
sinking fund payment date a sufficient principal amount of Securities of such series to absorb said cash, as nearly as may be, and shall (if requested in writing by the Issuer) inform the Issuer of the serial numbers of the Securities of such series
(or portions thereof) so selected. Securities of any series which are (a) owned by the Issuer or an entity known by a Responsible Officer of the Trustee to be directly or indirectly controlling or controlled by or under direct or indirect
common control with the Issuer, as shown by the Security register, and not known to a Responsible Officer of the Trustee to have been pledged or hypothecated by the Issuer or any such entity or (b) identified in an Officers’ Certificate at
least 60 days prior to the sinking fund payment date as being beneficially owned by, and not pledged or hypothecated by, the Issuer or an entity directly or indirectly controlling or controlled by or under direct or indirect common control with the
Issuer shall be excluded from Securities of such series eligible for selection for redemption. The Trustee, in the name and at the expense of the Issuer (or the Issuer, if it shall so request the Trustee in writing) shall cause notice of redemption
of the Securities of such series to be given in substantially the manner provided in Section 

  
 45 

 
11.02 (and with the effect provided in Section 11.03) for the redemption of Securities of such series in part at the option of the Issuer. The amount of any sinking fund payments not so
applied or allocated to the redemption of Securities of such series shall be applied to the next cash sinking fund payment for such series and, together with such payment, shall be applied in accordance with the provisions of this Section. Any and
all sinking fund moneys held on the stated maturity date of the Securities of any particular series (or earlier, if such maturity is accelerated), which are not held for the payment or redemption of particular Securities of such series shall be
applied, together with other moneys, if necessary, sufficient for the purpose, to the payment of the principal of, and interest on, the Securities of such series at maturity. 
 On or before the Business Day prior to each sinking fund payment date, the Issuer shall pay to the Trustee in cash or shall otherwise provide for the payment of all interest accrued to the date fixed for
redemption on Securities to be redeemed on the next following sinking fund payment date. 
 The Trustee shall not redeem or
cause to be redeemed any Securities of a series with sinking fund moneys or give any notice of redemption of Securities for such series by operation of the sinking fund during the continuance of a default in payment of interest on such Securities or
of any Event of Default except that, where the mailing of notice of redemption of any Securities shall theretofore have been made, the Trustee shall redeem or cause to be redeemed such Securities, provided that it shall have received from the Issuer
a sum sufficient for such redemption. Except as aforesaid, any moneys in the sinking fund for such series at the time when any such default or Event of Default shall occur, and any moneys thereafter paid into the sinking fund, shall, during the
continuance of such default or Event of Default, be deemed to have been collected under Article 4 and held for the payment of all such Securities. In case such Event of Default shall have been waived as provided in Section 4.10 or the default
cured on or before the 60th day preceding the sinking fund payment date in any year, such moneys shall thereafter be applied on the next succeeding sinking fund payment date in accordance with this Section to the redemption of such Securities.

 ARTICLE 12 
 GUARANTEE 
 Section 12.01. The Guarantee. The Guarantor hereby
unconditionally guarantees to each Holder of a Security authenticated and delivered by the Trustee the due and punctual payment of the principal of, any premium and interest on, and any additional amounts with respect to such Security and the due
and punctual payment of the sinking fund payments (if any) provided for pursuant to the terms of such Security, when and as the same shall become due and payable, whether at maturity, by acceleration, redemption, repayment or otherwise, in
accordance with the terms of such Security and of this Indenture. In case of the failure of the Issuer punctually to pay any such principal, premium, interest, additional amounts or sinking fund payment, the Guarantor hereby agrees to cause any such
payment to be made punctually when and as the same shall become due and payable, whether at maturity, upon acceleration, redemption, repayment or otherwise, and as if such payment were made by the Issuer. 

Section 12.02. Net Payments. Except as otherwise provided in any indenture supplemental hereto, all payments of principal of and
premium, if any, interest and any other amounts on, or in respect of, the Securities of any series shall be made by the Guarantor without withholding or deduction at source for, or on account of, any present or future taxes, fees, duties,
assessments or governmental charges of whatever nature imposed or levied by or on behalf of the State of Israel (the “taxing jurisdiction”) or any political subdivision or taxing authority thereof or therein, unless such taxes, fees,
duties, assessments or governmental charges are required to be withheld or deducted by (i) the laws (or any regulations or ruling promulgated thereunder) of a taxing jurisdiction or any political subdivision or taxing authority thereof or
therein or (ii) an official position regarding the application, administration, 

  
 46 

 
interpretation or enforcement of any such laws, regulations or rulings (including, without limitation, a holding by a court of competent jurisdiction or by a taxing authority in a taxing
jurisdiction or any political subdivision thereof). If a withholding or deduction at source is required, the Guarantor shall, subject to certain limitations and exceptions set forth below, pay to the Holder of any such Security such additional
amounts as may be necessary so that every net payment of principal, premium, if any, interest or any other amount made to such Holder, after such withholding or deduction, shall not be less than the amount provided for in such Security, and this
Indenture to be then due and payable; provided, however, that the Guarantor shall not be required to make payment of such additional amounts for or on account of: 
 (a) any tax, fee, duty, assessment or governmental charge of whatever nature which would not have been imposed but for the fact that such Holder: (A) was a resident, domiciliary or national of, or
engaged in business or maintained a permanent establishment or was physically present in, the relevant taxing jurisdiction or any political subdivision thereof or otherwise had some connection with the relevant taxing jurisdiction other than by
reason of the mere ownership of, or receipt of payment under, such Security; (B) presented such Security for payment in the relevant taxing jurisdiction or any political subdivision thereof, unless such Security could not have been presented
for payment elsewhere; or (C) presented such Security more than 30 days after the date on which the payment in respect of such Security first became due and payable or provided for, whichever is later, except to the extent that the Holder would
have been entitled to such additional amounts if it had presented such Security for payment on any day within such period of 30 days; 
 (b) any estate, inheritance, gift, sale, transfer, personal property or similar tax, assessment or other governmental charge; 
 (c) any tax, assessment or other governmental charge that is imposed or withheld by reason of the failure by the Holder or the beneficial owner of such Security to comply with any reasonable request by
the Guarantor addressed to the Holder within 90 days of such request (A) to provide information concerning the nationality, residence or identity of the Holder or such beneficial owner or (B) to make any declaration or other similar claim
or satisfy any information or reporting requirement, which, in the case of (A) or (B), is required or imposed by statute, treaty, regulation or administrative practice of the relevant taxing jurisdiction or any political subdivision thereof as
a precondition to exemption from all or part of such tax, assessment or other governmental charge; or 
 (d) any combination of
items (a), (b) and (c); 
 nor shall additional amounts be paid with respect to any payment of the principal of, or premium, if any,
interest or any other amounts on, any such Security to any Holder who is a fiduciary or partnership or other than the sole beneficial owner of such Security to the extent such payment would be required by the laws of the relevant taxing jurisdiction
(or any political subdivision or relevant taxing authority thereof or therein) to be included in the income for tax purposes of a beneficiary or partner or settlor with respect to such fiduciary or a member of such partnership or a beneficial owner
who would not have been entitled to such additional amounts had it been the Holder of the Security. 
 Section 12.03.
Guarantee Unconditional, etc. The Guarantor hereby agrees that its obligations hereunder shall be as principal and not merely as surety, and shall be absolute, irrevocable and unconditional, irrespective of, and shall be unaffected by, any
invalidity, irregularity or unenforceability of any Security or this Indenture, any failure to enforce the provisions of any Security or this Indenture, or any waiver, modification, consent or indulgence granted with respect thereto by the Holder of
such Security or the Trustee, the recovery of any judgment against the Issuer or any action to enforce the same, or any other circumstances which may otherwise constitute a legal or equitable discharge of a surety or guarantor. The Guarantor hereby
waives diligence, presentment, demand of payment, filing of claims 

  
 47 

 
with a court in the event of merger, insolvency or bankruptcy of the Issuer, any right to require a proceeding first against the Issuer, protest or notice with respect to any such Security or the
indebtedness evidenced thereby and all demands whatsoever, and covenants that this Guarantee will not be discharged except by payment in full of the principal of, any premium and interest on, and any additional amounts and sinking fund payments
required with respect to, the Securities and the complete performance of all other obligations contained in the Securities and this Indenture, as supplemented and amended from time to time. The Guarantor further agrees, to the fullest extent that it
lawfully may do so, that, as between the Guarantor, on the one hand, and the Holders and the Trustee, on the other hand, the maturity of the obligations guaranteed hereby may be accelerated as provided in Section 4.01 hereof for the purposes of
this Guarantee, notwithstanding any stay, injunction or prohibition extant under any bankruptcy, insolvency, reorganization or other similar law of any jurisdiction preventing such acceleration in respect of the obligations guaranteed hereby.

 Section 12.04. Reinstatement. This Guarantee shall continue to be effective or be reinstated, as the case may be, if
at any time payment on any Security, in whole or in part, is rescinded or must otherwise be restored to the Issuer or the Guarantor upon the bankruptcy, liquidation or reorganization of the Issuer or otherwise. 

Section 12.05. Subrogation. The Guarantor shall be subrogated to all rights of the Holder of any Security against the Issuer in
respect of any amounts paid to such Holder by the Guarantor pursuant to the provisions of this Guarantee; provided, however, that the Guarantor shall not be entitled to enforce, or to receive any payments arising out of or based upon, such right of
subrogation until the principal of, any premium and interest on, and any additional amounts and sinking fund payments required with respect to, all Securities shall have been paid in full. 

Section 12.06. Assumption by Guarantor. 
 (a) The Guarantor may, without the consent of the Holders, assume all of the rights and obligations of the Issuer hereunder with respect to a series of Securities and under the Securities of such series
if, after giving effect to such assumption, no Event of Default or event which with the giving of notice or lapse of time, or both, would become an Event of Default, shall have occurred and be continuing. Upon such an assumption, the Guarantor shall
execute a supplemental indenture evidencing its assumption of all such rights and obligations of the Issuer and the Issuer shall be released from its liabilities hereunder and under such Securities as obligor on the Securities of such Series.

 (b) The Guarantor shall assume all of the rights and obligations of the Issuer hereunder with respect to a series of
Securities and under the Securities of such series if, upon a default by the Issuer in the due and punctual payment of the principal, sinking fund payment, if any, premium, if any, or interest on such Securities, the Guarantor is prevented by any
court order or judicial proceeding from fulfilling its obligations under Section 12.01 with respect to such series of Securities. Such assumption shall result in the Securities of such series becoming the direct obligations of the Guarantor and
shall be effected without the consent of the Holders of the Securities of any Series. Upon such an assumption, the Guarantor shall execute a supplemental indenture evidencing its assumption of all such rights and obligations of the Issuer, and the
Issuer shall be released from its liabilities hereunder and under such Securities as obligor on the Securities of such Series.
