year.” 
  

	 	2.	Section 7 of the Letter Agreement is hereby amended to add immediately following the words “In addition to the foregoing lump-sum payment”, a new
subsection (v) which reads as follows: 

 “(v) You will receive the portion of your
Annual Bonus for the fiscal year of termination that is tied to the achievement of the Company’s performance objectives for such fiscal year, based on the Company’s actual achievement of such performance objectives for the full fiscal
year, pro-rated for the number of days that have elapsed during such fiscal year prior to the termination of your employment. You will receive any portion of your Annual Bonus for the fiscal year of termination that is tied to achievement of
personal objectives for such fiscal year at “Target” level for the achievement of such personal objectives, pro-rated for the number of days that have elapsed during such fiscal year prior to the termination of your employment. The payment

 In any case where several matters are required to be certified by, or covered by an opinion of, any specified Person, it is not necessary that all such matters be certified by, or covered by the opinion

provided such action shall become effective when such instrument or instruments are delivered to the Trustee and, where it is hereby expressly required, to the Company. Such instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the “Act” of the Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this
Indenture and (subject to Section 6.1) conclusive in favor of the Trustee and the Company, if made in the manner provided in this Section. 
 (b) The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer
authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to 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
manner which the Trustee deems sufficient. 
 (c) Subject to TIA Section 316(c), the Company may fix any day as the record
date for the purpose of determining the Holders of Securities of any series entitled to give or take any request, demand, authorization, direction, notice, consent, waiver or other action, or to vote on any action, authorized or permitted by this
Indenture to be given or taken by Holders of Securities of such series. If not set by the Company prior to the first solicitation of a Holder of Securities of such series made by any Person in respect of any such action, or, in the case of any such
vote, prior to such vote, the record date for any such action or vote shall be the 30th day (or, if later, the date of the most recent list of Holders required to be provided pursuant to Section 7.1) prior to such first solicitation or
vote, as the case may be. With regard to any record date for action to be taken by the Holders of one or more series of Securities, only the Holders of Securities of such series on such date (or their duly designated proxies) shall be entitled to
give or take, or vote on, the relevant action. 
 (d) The ownership of Securities shall be proved by the Security Register.

 (e) Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Security shall
bind every future Holder of the same Security and the Holder of every Security issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee or
the Company in reliance thereon, whether or not notation of such action is made upon such Security. 
 Section 1.7 Notices, Etc., to
Trustee and Company. 
 (a) 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 Trust Administration, or 

(2) the Company by the Trustee or by any Holder shall be sufficient for every purpose hereunder (unless otherwise herein
expressly provided) if in writing and mailed, first-class postage prepaid, to the Company addressed to it at the address of its principal office specified in the first paragraph of this instrument or at any other address previously furnished in

 Section 1.8 Notice to
Holders; Waiver. 
 Where this Indenture provides for notice to Holders of any event, such notice shall be sufficiently given
(unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to each Holder affected by such event, at his address as it appears in the Security Register, not later than the latest date (if any), and not
earlier than the earliest date (if any), prescribed for the giving of such notice. 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. 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. 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 regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such notification as shall be made with the approval
of the Trustee shall constitute a sufficient notification for every purpose hereunder. 
 Section 1.9 Conflict with Trust Indenture Act.

 If any provision hereof limits, qualifies or conflicts with a provision of the TIA that is required under such Act to be a
part of and govern this Indenture, the latter provision shall control. If any provision of this Indenture modifies or excludes any provision of the TIA that may be so modified or excluded, the latter provision shall be deemed to apply to this
Indenture as so modified or to be excluded, as the case may be.

Separability Clause. 
 In case any provision in this Indenture or in the Securities shall be invalid, illegal or
unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. 
 Section 1.13 Benefits of Indenture. 
 Nothing in this Indenture or in the Securities, express or implied,
shall give to any Person, other than the parties hereto and their successors hereunder and the Holders, any benefit or any legal or equitable right, remedy or claim under this Indenture.

 THIS INDENTURE AND THE SECURITIES SHALL
BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO ANY CONFLICTS OF LAWS PRINCIPLES INCONSISTENT THEREWITH. 
 Section 1.15 Legal Holidays. 
 In any case where any Interest Payment
Date, Redemption Date, Stated Maturity or Maturity of any Security shall not be a Business Day at any Place of Payment, then (notwithstanding any other provision of this Indenture or of the Securities (other than a provision of the Securities of any
series which specifically states that such provision shall apply in lieu of this Section)) payment of interest or principal (and premium, if any) need not be made at such Place of Payment on such date, but may be made on the next succeeding Business
Day at such Place of Payment with the same force and effect as if made on the Interest Payment Date, the Redemption Date, or at the Stated Maturity or Maturity; provided that, no interest shall accrue for the intervening period.

Depositary or its nominee only in the limited circumstances described in the Indenture and may not be transferred except as a whole by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another

entity as is requested by an authorized representative of [insert name of nominee]), any transfer, pledge or other use hereof for value or otherwise by or to any person is wrongful inasmuch as the registered owner hereof, [insert name of nominee],

 (b) Members of, or Participants in, the Depositary (“Agent Members”) shall have no rights under this Indenture with respect
to any Global Security held on their behalf by the Depositary, or the Trustee as its custodian, or under the Global Security, and the Depositary may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute
owner of the Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other
authorization furnished by the Depositary or impair, as between the Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights of a Holder of any Security. 
 (c) Transfers of any Global Security shall be limited to transfers in whole, but not in part, to the Depositary, its successors or their
representative nominees. Except as provided below, owners of beneficial interests in Global Securities will not be entitled to receive Physical Securities. If required to do so pursuant to any applicable law or regulation, beneficial owners may
obtain Physical Securities in exchange for their beneficial interests in a Global Security upon written request in accordance with the Depositary’s and the Security Registrar’s procedures. In addition, Physical Securities shall be
transferred to all beneficial owners in exchange for their beneficial interests in a Global Security of a particular series if (1) the Depositary notifies the Company that it is unwilling or unable to continue as depositary for such Global
Security or the Depositary ceases to be a clearing agency registered under the Exchange Act, at a time when the Depositary is required to be so registered in order to act as depositary, and in each case a successor depositary is not appointed by the
Company within ninety (90) days of such notice, or (2) the Company executes and delivers to the Trustee and Security Registrar an Officers’ Certificate stating that such Global Security shall be so exchangeable, or (3) an Event

Securities or otherwise applicable under the Securities Act reflect on its books and records the date and a decrease in the principal amount of the beneficial interest in such Global Security to be transferred, and the Company shall execute, and the
Trustee shall authenticate and deliver, one or more Physical Securities of like tenor and amount. 
 (e) In connection with the
transfer of an entire Global Security to beneficial owners in the form of Physical Securities pursuant to Section 2.4(c), such Global Security shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall

such Security for all purposes of this Indenture, and neither the Company, the Security Registrar nor the Trustee shall have any responsibility or obligation to any Agent Members or other beneficial owners of the Securities represented by such

 Section 3.3 Execution, Authentication, Delivery and Dating. 
 (a) The Securities shall be executed on behalf of the Company by its Chairman of the Board, its Chief Executive Officer, its President, its Chief Financial Officer or one of its Vice Presidents, under its
corporate seal reproduced thereon attested by its Secretary or one of its Assistant Secretaries. The signature of any of these officers on the Securities may be manual, facsimile or electronic. 
 (b) Securities bearing the manual, facsimile or electronic signatures of individuals who were at any time the proper officers of the Company
shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at the date of such Securities. 
 (c) At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities of any series
executed by the Company to the Trustee for authentication, together with an Order of the Authentication for the authentication and delivery of such Securities (an “Authentication Order”), and the Trustee in accordance with the
Authentication Order shall authenticate and deliver or make available for delivery such Securities; provided, however, that in the case of Securities of a series that are not to be originally issued at one time, the Trustee shall authenticate
and deliver or make available for delivery such Securities from time to time in accordance with such other procedures (including, without limitation, the receipt by the Trustee of oral or electronic instructions from the Company or its duly
authorized agents, promptly confirmed in writing) acceptable to the Trustee as may be specified by or pursuant to an Authentication Order delivered to the Trustee prior to the time of the first authentication of Securities of such series. If the
form or forms or terms of the Securities of the series have been established in or pursuant to one or more Board Resolutions or pursuant to authority granted by one or more Board Resolutions as permitted by Sections 2.1 and
Section 3.1, 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 6.1) shall
be fully protected in relying upon, an Opinion of Counsel stating: 
 (1) if the form or forms of such Securities
have been established by or pursuant to Board Resolution or pursuant to authority granted by one or more Board Resolutions as permitted by Section 2.1, that such form or forms have been established in conformity with the provisions of
this Indenture; 
 (2) if the terms of such Securities have been, or in the case of Securities of a series that
are not to be originally issued at one time, will be established by or pursuant to Board Resolution or pursuant to authority granted by one or more Board Resolutions as permitted by Section 3.1, that such terms have been, or in the case
of Securities of a series that are not to be originally issued at one time, will be established in conformity with the provisions of this Indenture, subject, in the case of Securities of a series that are not to be originally issued at one time, to
any conditions specified in such Opinion of Counsel; and 
 (3) that such Securities, when authenticated and
delivered by the Trustee and issued by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute valid and legally binding obligations of the Company enforceable in accordance with their terms,
subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles; provided that, such Opinion of
Counsel need express no opinion as to whether a court in the United States would render a money judgment in currency other than that of the United States. 
 (d) If such form or forms or terms have been so established, the Trustee shall not be required to authenticate such Securities if the issue of such Securities pursuant to this Indenture will adversely
affect the Trustee’s own rights, duties or immunities under the Securities and this Indenture or otherwise in a manner which the Trustee determines would expose it to personal liability. 
 (e) Notwithstanding the provisions of Section 3.1 and of Section 3.3(d), if all Securities of a series are not to be
originally issued at one time, it shall not be necessary to deliver the Officers’ Certificate otherwise required pursuant to Section 3.1 or the Authentication Order and Opinion of Counsel otherwise required pursuant to such
preceding paragraph at or prior to the time of authentication of each Security of such series if such documents, with appropriate modifications to cover such future issuances, are delivered at or prior to the authentication upon original issuance of
the first Security of such series to be issued. 
 (f) If the Company shall establish pursuant to Section 3.1 that
the Securities of a series are to be issued in whole or in part in the form of one or more Global Securities, then the Company shall execute and the Trustee shall, in accordance with this Section and the Authentication Order with respect to such
series, authenticate and deliver or make available for delivery one or more Securities in such form that (1) shall represent and shall be denominated in an amount equal to the aggregate principal amount of the Outstanding Securities of such
series to be represented by such Global Security or Global Securities, (2) shall be registered in the name of the Depositary for such Global Security or Global Securities or the nominee of such Depositary, (3) shall be delivered by the
Trustee to such Depositary or pursuant to such Depositary’s instruction, and (4) shall bear the legend(s) set forth in Section 2.2. 
  

 9 

 (g) Unless otherwise established pursuant to Section 3.1, each Depositary
designated pursuant to Section 3.1 for a Global Security must, at the time of its designation and at all times while it serves as Depositary, be a clearing agency registered under the Exchange Act and any other applicable statute or
regulation. The Trustee shall have no responsibility to determine if the Depositary is so registered. Each Depositary shall enter into an agreement with the Trustee governing the respective duties and rights of such Depositary and the Trustee with
regard to Global Securities. 
 (h) Each Security shall be dated the date of its authentication. 
 (i) No Security shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such
Security a certificate of authentication substantially in the form provided for herein executed by the Trustee by manual signature of an authorized officer thereof, and such certificate upon any Security shall be conclusive evidence, and the only
evidence, that such Security has been duly authenticated and delivered hereunder. Notwithstanding the foregoing, if any Security shall have been authenticated and delivered hereunder but never issued and sold by the Company, and the Company shall
deliver such Security to the Trustee for cancellation as provided in Section 3.9, for all purposes of this Indenture such Security shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to
the benefits of this Indenture. 
 Section 3.4 Temporary Securities. 
 Pending the preparation of definitive Securities of any series, the Company may execute, and upon an Authentication Order the Trustee shall
authenticate and deliver or make available for delivery, temporary Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities
in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may determine, as evidenced by their execution of such Securities. 
 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 the Company shall execute and the Trustee shall authenticate
and deliver or make available for delivery in exchange therefor one or more definitive Securities of the same series, of any authorized denominations and of a like aggregate principal amount and tenor. 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 and tenor. 
 Section 3.5 Registration; Registration of Transfer and Exchange. 
 (a) The Company shall cause to be kept
at the Corporate Trust Office of the Trustee a register (the register maintained in such office and in any other office or agency of the Company in a Place of Payment being herein sometimes collectively referred to as the “Security
Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Securities and of transfers of Securities. The Trustee is hereby appointed “Security Registrar” for
the purpose of registering Securities and transfers of Securities as herein provided. 
 (b) Notwithstanding anything herein to
the contrary, there shall be only one Security Register with respect to each series of Securities. 
 (c) Upon surrender for
registration of transfer of any Security of any series at the 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 or make available for delivery, in the
name of the designated transferee or transferees, one or more new Securities of the same series, of any authorized denominations and of a like aggregate principal amount and tenor. 
 (d) At the option of the Holder, Securities of any series may be exchanged for other Securities of the same series, of any authorized
denominations and of a like aggregate principal amount and tenor, upon surrender of the Securities to be exchanged at such office or agency. 
 (e) Whenever any Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver or make available for delivery, the Securities which the Holder
making the exchange is entitled to receive. 
 (f) 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. 
 (g) Every Security presented or surrendered for registration of transfer or for exchange shall (if so required by the Company, the Security
Registrar or the Trustee) be duly endorsed or be accompanied by a written instrument of transfer in form satisfactory to the Company, the Security Registrar and the Trustee duly executed, by the Holder thereof or his attorney duly authorized in
writing. 
 (h) No service charge shall be made for any registration of transfer or exchange of Securities, but the Company may
require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 3.4,
Section 9.6 or Section 11.7 not involving any transfer. 
 (i) The Company shall not be required
(1) to issue, register the transfer of or exchange Securities of any series during a period beginning at the opening of business fifteen (15) days before the day of the mailing of a notice of redemption of Securities of that series
selected for redemption under Section 11.3 and ending at the close of business on the day of such mailing, or (2) to register the transfer of or exchange any Security so selected for redemption in whole or in part, except the
unredeemed portion of any Security being redeemed in part. 
 (j) Notwithstanding the foregoing, any Global Security shall be
exchangeable pursuant to this Section 3.5 for Securities registered in the names of Persons other than the Depositary for such Security or its nominee only if (1) such Depositary notifies the Company that it is unwilling or unable
to continue as Depositary for such Global Security or if at any time such Depositary ceases to be a clearing agency registered under the Securities Exchange Act of 1934, as amended and the Company does not appoint a successor Depositary within
ninety (90) days after receipt by it of such notice or after it becomes aware of such cessation, (2) the Company executes and delivers to the Trustee an Order of the Company that such Global Security shall be so exchangeable or
(3) there shall have occurred and be continuing an Event of Default with respect to the Securities. Any Global Security that is exchangeable pursuant to the preceding sentence shall be exchangeable for Securities registered in such names as
such Depositary shall direct. 
 (k) Notwithstanding any other provision in this Indenture, unless and until it is exchanged in
whole or in part for Securities that are not in the form of a Global Security, a Global Security may not be transferred or exchanged except as a whole by the Depositary with respect to such Global Security to a nominee of such

  

 10 

 
Depositary or by a nominee of such Depositary to such Depositary or another nominee of such Depositary. 
 (l) 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 in a Global Security or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests. 
 Section 3.6 Mutilated, Destroyed, Lost and Stolen Securities. 
 If any
mutilated Security is surrendered to the Trustee, the Company shall execute and the Trustee shall authenticate and deliver or make available for delivery in exchange therefor a new Security of the same series and of like tenor and principal amount
and bearing a number not contemporaneously outstanding. 
 If there shall be delivered to the Company and the Trustee
(i) evidence to their satisfaction of the destruction, loss or theft of any Security and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of
notice to the Company or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute and the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security, a new Security of
the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding. 
 In case any
such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Security, pay such Security. 
 Upon the issuance of any new Security under this Section, the Company may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith. 
 Every new Security of any series issued pursuant to this Section in lieu of any destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company, whether or
not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities of that series duly issued hereunder.

 The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with
respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities. 
 Section 3.7 Payment of Interest; Interest
Rights Preserved. 
 (a) Except as otherwise provided as contemplated by Section 3.1 with respect to any series
of Securities, interest on any Security which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name 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 maintained for such purpose pursuant to Section 10.2; provided, however, that at the option of the Company, interest on Securities of any
series that bear interest may be paid (i) by check mailed to the address of the Person entitled thereto as it shall appear on the Security Register or (ii) by wire transfer to an account maintained by the Person entitled thereto as
specified in the Security Register; provided that, such Person shall have given the Trustee written wire instructions at least five (5) Business Days prior to the applicable Interest Payment Date. 
 (b) Any interest on any Security of any series which 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 Holder on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company, at its
election in each case, as provided in clause (1) or (2) below: 
 (1) The Company may elect to make
payment of any Defaulted Interest to the Persons in whose names the 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 Security of such series and the date of the proposed payment, and at the same time the
Company shall deposit with the Trustee an amount of money 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 prior to the date of the
proposed payment such money, when deposited, to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this Clause provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted
Interest which shall be not more than fifteen (15) days and not less than ten (10) days prior to the date of the proposed payment and not less than ten (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 Securities of such series at his address as it appears in the Security Register, not less than ten (10) days prior to such Special Record Date. Notice of the proposed payment of such Defaulted
Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of
business on such Special Record Date and shall no longer be payable pursuant to the following clause (2). 
 (2)
The Company may make payment of any Defaulted Interest on the Securities of any series in any other lawful manner not inconsistent with the requirements of any securities exchange on which such Securities may be listed, and upon such notice as may
be required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this Clause, such manner of payment shall be deemed practicable by the Trustee. 
 (c) Subject to the foregoing provisions of this Section, each Security delivered under this Indenture upon registration of transfer of or in
exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security. 
 Section 3.8 Persons Deemed Owners. 
 Prior to due presentment of a
Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such Security is registered as the owner of such Security for the purpose of receiving payment of
principal of and any premium and (subject to Section 3.7) any interest on such Security and for all other purposes whatsoever, whether or not such Security be overdue, and neither the Company, the Trustee nor any agent of the Company or
the Trustee shall be affected by notice to the contrary. 
 Section 3.9 Cancellation. 
 All Securities surrendered for payment, redemption, 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. All Securities so delivered and any Securities surrendered directly to the Trustee for any such purpose

  

 11 

 
shall be promptly canceled by the Trustee and such cancellation shall be noted conspicuously on each such Security. 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. 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. All canceled Securities held by the Trustee shall be disposed of as directed by an Order of the Company or after ninety (90) days, if not in receipt of such Order of the Company,
shall be disposed of in accordance with the Trustee’s customary procedures. The Trustee shall provide the Company a list of all Securities that have been cancelled from time to time as requested by the Company. 
 Section 3.10 Computation of Interest. 
 Except as otherwise specified as contemplated by Section 3.1 for Securities of any series, interest on the Securities of each series shall be computed on the basis of a 360-day year of twelve
30-day months. 
 Section 3.11 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 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 CUSIP numbers. The Company will promptly notify the Trustee of any change in the CUSIP numbers.

 Section 3.12 Original Issue Discount. 
 If any of the Securities is an Original Issue Discount Security, the Company shall file with the Trustee as soon as practicable following at the end of each calendar year (1) a written notice
specifying the amount or original issue discount (including daily rates and accrual periods) accrued on such Outstanding Original Issue Discount Securities as of the end of such year and (2) such other specific information relating to such
original issued discount as may then be relevant under the Internal Revenue Code and reasonably available to the Company.

 (a) If an Event of Default (other than an Event of Default described in Section 5.1(a)(5) or
Section 5.1(a)(6)) with respect to Securities of any series at the time Outstanding occurs and is continuing, then in every such case (1) the Trustee by written notice to the Company, or (2) the Holders of not less than 25% in
principal amount of the Outstanding Securities of that series by written notice to the Company and Trustee, may declare the principal amount (or, if any of the Securities of that series are Original Issue Discount Securities or indexed securities,
such portion of the principal amount of such Securities as may be specified in the terms thereof) of all of the Securities of that series to be due and payable immediately and upon any such declaration such principal amount (or, in the case of
Original Issue Discount Securities or indexed securities, such specified amount) shall become immediately due and payable, provided however, that if any Credit Agreement (as such term may be defined in any supplemental indenture) shall be at
any time or from time to time in force and effect and if an Event of Default shall have occurred and be continuing (other than an Event of Default specified in Section 5.1(a)(5) or Section 5.1(a)(6)), then, unless otherwise
provided in a supplemental indenture, any such acceleration shall not be effective until the earlier to occur of:

 (D) all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances
of the Trustee, its agents and counsel; and 
 (2) all Events of Default with respect to Securities of that
series, other than the non-payment of the principal of Securities of that series which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 5.13. 
  

 13 

 (c) No such rescission shall affect any subsequent default or impair any right consequent
thereon. 
 (d) If an Event of Default described in Section 5.1(a)(6) or Section 5.1(a)(7) occurs, the
Outstanding Securities shall ipso facto become immediately due and payable without need of any declaration or other act on the part of the Trustee or any Holder. 
 Section 5.3 Right of Holders to Receive Payment and Suits for Enforcement by Trustee. 
 If an Event of Default specified in Section 5.1(a)(1) or Section 5.1(a)(2) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express
trust against the Company, any Guarantor or any other obligor on the Securities for the whole amount of principal of, premium, if any, and accrued interest (including any additional interest applicable with respect to Securities of any series),
together with interest on overdue principal and, to the extent that payment of such interest is lawful, interest on overdue installments of interest, in each case at the rate per annum borne by the Securities and 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. 
 Section 5.4 Trustee May File Proofs of Claim. 
 In case of any judicial
proceeding relating to the Company (or any other obligor upon the Securities), its property or its creditors, the Trustee shall be entitled and empowered, by intervention in such proceeding or otherwise, to take any and all actions authorized under
the TIA in order to have claims of the Holders and the Trustee allowed in any such proceeding. In particular, the Trustee shall be authorized to collect and receive any moneys or other property payable or deliverable on any such claims and to
distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments directly to the Trustee and, in the
event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and
any other amounts due the Trustee under Section 6.7. 
 No provision of this Indenture shall be deemed to authorize
the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding; provided, however, that the Trustee may, on behalf of the Holders, vote for the election of a trustee in bankruptcy or similar official and may be a member of a creditors’ or
other similar committee. 
 Section 5.5 Trustee May Enforce Claims Without Possession of Securities. 
 All rights of action and claims under this Indenture or the Securities may be prosecuted and enforced by the Trustee without the possession
of any of the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after
provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Securities in respect of which such judgment has been recovered.

 Section 5.6 Application of Money Collected. 
 If the Trustee collects any money pursuant to this Article 5, it shall pay out such money in the following order:

kind, according to the amounts due and payable on the Securities for principal (including any premium); and 
 Fourth: the
balance, if any, to the Company or to the extent the Trustee collects any amount from any Guarantor, to such Guarantor.

Trustee, upon prior written notice to the Company, may fix a record date and payment date for any payment to Holders pursuant to this Section 5.6. 
 Section 5.7 Limitation on Suits. 
 (a) No Holder of any Security of any
series shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver, assignee, trustee, liquidator or sequestrator (or similar official) or for any other remedy
hereunder, unless 
 (1) such Holder gives 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;

and liabilities to be incurred in compliance with such request; 
 (4) the Trustee does not comply with the
request within sixty (60) days after its receipt of such notice, request and offer, and, if requested, indemnity; and 
 (5) before or during such 60-day period by the Holders of a majority in principal amount of the Outstanding Securities of that series do not give the Trustee a direction which is inconsistent with the
request; 
 (b) The foregoing limitations shall not apply to a suit instituted by a Holder for the enforcement of the payment of
principal of, premium, if any, or accrued interest on, such Security on or after the respective due dates set forth in such Security. 
 (c) 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 Holders, or to obtain or to seek to
obtain priority or preference over any other Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all Holders.

 Section 5.8 Unconditional Right of Holders to Receive Principal, Premium and Interest.

 Notwithstanding any other provision in this Indenture, the Holder of any Security shall have the right, which is absolute
and unconditional, to receive payment of the principal of and any premium, if any, and (subject to Section 3.7) any interest on such Security on the Stated Maturity or Maturities expressed in such Security (or, in the case of redemption,
on the Redemption Date) and to institute suit for the enforcement of any such payment, and such rights shall not be impaired without the consent of such Holder. 
 Section 5.9 Restoration of Rights and Remedies. 
 If the Trustee or any
Holder has instituted any proceeding to enforce any right or remedy under this Indenture, any Security, or any Guarantee and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to
such Holder, then and in every such case, subject to any determination in such proceeding, the Company, each Guarantor, if any, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and
thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted. 
 Section 5.10 Rights and Remedies Cumulative. 
 Except as otherwise provided with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Securities in the last paragraph of Section 3.6 and as otherwise provided in Section 5.7, no right or remedy herein conferred upon or reserved to the Trustee or to the
Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or
in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. 
 Section 5.11 Delay or Omission Not Waiver. 
 No delay or omission of the Trustee or of any Holder of any Securities to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of
any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the
Holders, as the case may be. 
 Section 5.12 Control by Holders. 
 The Holders of not less than a majority in aggregate principal amount of the Outstanding Securities shall have the right to direct the time,
method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, provided, however, that the Trustee may refuse to follow any direction (1) that conflicts
with any rule of law or this Indenture, (2) that the Trustee determines may be unduly prejudicial to the rights of another Holder, or (3) that may expose the Trustee to personal liability unless the Trustee has been provided reasonable
indemnity against any loss or expense caused by its following such direction; and provided further that the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. 
 Section 5.13 Waiver of Past Defaults. 
 (a) The Holders of not less than a majority in principal amount of the Outstanding Securities of any series may on behalf of the Holders of all the Securities of such series waive any past default
hereunder with respect to such series and its consequences, except a default 
 (1) in the payment of the
principal of or any premium, if any, or interest on any Security of such series, or 
 (2) in respect of a
covenant or provision hereof which under Article 9 cannot be modified or amended without the consent of the Holder of each Outstanding Security of such series affected. 
 (b) 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 impair any right consequent thereon. 
 Section 5.14 Undertaking for Costs. 
 In any suit for the enforcement of any right or remedy under this
Indenture, or in any suit against the Trustee for any action taken, suffered or omitted by it as Trustee, a court may require any party litigant in such suit to file an undertaking to pay the costs of such suit, and may assess reasonable costs,
including counsel fees and expenses, against any such party litigant, in the manner and to the extent provided in the TIA; provided that, neither this Section nor the TIA shall be deemed to authorize any court to require such an undertaking
or to make such an assessment in any suit instituted by the Company, the Trustee or the Holders of more than 10% in aggregate principal amount of the Outstanding Securities of any series or to any suit instituted by any Holder 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 6

 THE TRUSTEE 
 Section 6.1 Certain Duties and Responsibilities. 
 (a) In case an Event of Default has occurred and is
continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in its exercise, as a prudent Person would exercise or use under the circumstances in the conduct of such
Person’s own affairs. 
 (b) Except during the continuance of an Event of Default: 
 (1) the duties of the Trustee shall be determined solely by the express provisions of the Indenture and the Trustee
undertakes to perform only such duties as are specifically set forth in this Indenture, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and 
 (2) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the
correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, in the case of any such certificates or opinions which by any provision hereof are
specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the certificates and opinions to determine whether or not they conform to the requirements of this Indenture (but need not confirm or investigate the
accuracy of mathematical calculations or other facts purported to be stated therein). 
  

 15 

 (c) No provision of this Indenture shall be construed to relieve the Trustee from liability
for its own bad faith, its own grossly negligent action, its own grossly negligent failure to act or its own willful misconduct, except that : 
 (1) this Section 6.1(c) does not limit the effect of Section 6.1(b); 
 (2) the Trustee shall not be liable for any error of judgment made in good faith by a Trust Officer, unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; and 

(3) the Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with
a direction received by it pursuant to Section 5.12. 
 (d) 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
funds or adequate indemnity against such risk or liability is not reasonably assured to it. 
 (e) Whether or not expressly so
provided, every provision of this Indenture that in any way relates to the Trustee is subject to Section 6.1(a) through Section 6.1(d). 
 (f) The Trustee shall not be liable for interest on any money or assets received by it except as the Trustee may agree in writing with the Company. Money or assets held in trust by the Trustee need not be
segregated from other funds or assets except to the extent required by law. 
 Section 6.2 Notice of Defaults. 
 Within ninety (90) days after the occurrence of any default hereunder with respect to Securities of any series and if actually known to
the Trustee, the Trustee shall mail to all Holders of Securities of such series, as their names and addresses appear in the Security Register, notice of such default hereunder, unless such default shall have been cured or waived before the giving of
such notice; provided, however, that, except in the case of a default in the payment of the principal of (or premium, if any) or interest on Securities of any series or in the payment of any sinking fund installment with respect to Securities
of such series, the Trustee shall be protected in withholding such notice if and so long as the board of directors, the executive committee or a trust committee of directors and/or Responsible Officers of the Trustee in good faith determine that the
withholding of such notice is in the interest of the Holders of Securities of such series; and provided, further, that in the case of any default of the character specified in Section 5.1(4) with respect to Securities of such series no
such notice to Holders shall be given until at least thirty (30) days after the occurrence thereof. For the purpose of this Section, the term “default” means any event which is, or after notice of lapse of time or both would become,
an Event of Default with respect to Securities of such series. Subject to TIA Section 315(b), the Trustee shall not be deemed to have, or be required to take, notice of any default or Event of Default (other than a default described in (a)(1)
through (3) of Section 5.1) except upon (a) written notification from the Company, or (b) written notification from a Holder and, in the absence of such notice, the Trustee may conclusively presume that there is no default
or Event of Default except as aforesaid. 
 Section 6.3 Certain Rights of Trustee. 
 (a) Subject to the provisions of Section 6.1 and the provisions of TIA Section 315: 
 (1) the Trustee may conclusively rely and shall be protected in acting or refraining from acting upon any resolution,
certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document (whether in its original or facsimile form) believed by it to be
genuine and to have been signed or presented by the proper Person. The Trustee need not investigate any fact or matter stated in the document; 
 (2) any request or direction of the Company mentioned herein shall be sufficiently evidenced by a Request of the Company or Order of the Company and any resolution of the Board of Directors may be
sufficiently evidenced by a Board Resolution; 
 (3) 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; 
 (4) the Trustee may consult with counsel of its selection 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; 
 (5) 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 pursuant to this Indenture, unless such Holders shall have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities which might be incurred by it in compliance
with such request or direction; 
 (6) the Trustee shall not be bound to make any investigation into the facts or
matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document, but the Trustee, in its discretion,
may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the
Company, personally or by agent or attorney; 
 (7) 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 and the Trustee shall not be responsible for any misconduct (except for willful misconduct)or negligence (except for gross negligence) on the part of any agent or
attorney appointed with due care by it hereunder; 
 (8) unless otherwise specifically provided in this
Indenture, any demand, request, direction or notice from the Company shall be sufficient if signed by an Officer of the Company and the Trustee shall be entitled to rely on such demand, request, direction, or notice, from and to the extent permitted
by this Indenture and not otherwise prohibited by or inconsistent with the TIA; 
 (9) the Trustee shall not be
deemed to have knowledge of any Default or Event of Default except (A) any Event of Default occurring pursuant to Section 5.1(a) or Section 5.1(b), or (B) any Event of Default of which a Trust Officer of the Trustee
shall have received written notification or otherwise obtained actual knowledge; 
 (10) whenever by the terms of
this Indenture, the Trustee shall be required to transmit notices or reports to any or all Holders, the Trustee shall be entitled to rely on the information provided by the Security Registrar as to the names and addresses of the Holders as being
correct. If the Security Registrar is other than the Trustee, the Trustee shall not be responsible for the accuracy of such information; 
 (11) 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 (including as Security Registrar), and to each agent, custodian, and any other such Persons employed to act hereunder; 
 (12) the Trustee is not required to give any bond or surety with respect to the performance of its duties or the exercise of
its powers under this Indenture; 
  

 16 

 (13) whenever any provision of this Indenture indicates that any
confirmation of a condition or event is qualified by the words “to the knowledge of” or “known to” the Trustee or words of similar meaning, said words shall mean and refer to the current awareness of one or more Trust Officers;

 (14) the Trustee shall not be liable for any action taken, suffered, or omitted to be taken 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 the Indenture; 
 (15) in no event shall the Trustee be responsible or liable for special, indirect 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; and 
 (16) 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 or 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 avoid and mitigate the effects of such occurrences and to resume performance as soon as
practicable under the circumstances). 
 (b) Subject to the above provisions, the Holders of not less than a majority in
aggregate principal amount of the Outstanding Securities 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 under this
Indenture.

 Section 6.5 May Hold Securities and Serve as Trustee Under Other Indentures. 
 The Trustee, any Authenticating Agent, any Paying Agent, any Security Registrar or any other agent of the Company, in its individual or any other capacity, may become the owner or pledgee of Securities
and, subject to Section 6.8 and Section 6.13 of this Indenture and TIA Sections 310 and 311, may otherwise deal with the Company with the same rights it would have if it were not Trustee, Authenticating Agent, Paying Agent,

disbursements and advances incurred or made by the Trustee in accordance with any provision of this Indenture (including the reasonable compensation and the expenses and disbursements of its agents and counsel), provided, however, Trustee
shall provide the Company reasonable advance notice of any expenditure not in the ordinary course of business and further provided, however, that the Company shall have no obligation to reimburse the Trustee with respect to any such expense,
disbursement or advance as may be attributable to the Trustee’s negligence, willful misconduct or bad faith; and 
 (3) to indemnify each of the Trustee, or any predecessor Trustee, for, and to hold it harmless against, any and all loss, liability, damage, claim or expense incurred without negligence or willful misconduct on its part, arising out of or

or duties hereunder. 
 The Trustee shall have a lien prior to the Securities upon all property and funds held by it hereunder

with an Event of

  

 17 

 
Default specified in Section 5.1(a)(5) or Section 5.1(a)(6), 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. 
 The provisions of this Section shall survive the satisfaction and discharge of this Indenture and the resignation or removal of the Trustee. 
 Section 6.8 Disqualification; Conflicting Interests. 
 If the Trustee
has or shall acquire a conflicting interest within the meaning of the TIA, the Trustee shall either eliminate such conflict, apply to the SEC for permission to continue as Trustee, or resign, to the extent and in the manner provided by, and subject
to the provisions of, the TIA and this Indenture. 
 To the extent permitted by the TIA, the Trustee shall not be deemed to have

 Section 6.9 Corporate Trustee Required; Eligibility. 
 There shall at all times be a Trustee hereunder
which shall be a Person that is eligible pursuant to the TIA to act as such and has a combined capital and surplus of at least $50,000,000. If such Person publishes reports of condition at least annually, pursuant to law or to the requirements of
any federal or state supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such 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 6.10 Resignation and Removal; Appointment of Successor. 
 (a) No resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this Article shall become effective until the acceptance of appointment by the successor Trustee in
accordance with the applicable requirements of Section 6.11. 
 (b) The Trustee may resign at any time with respect
to the Securities of one or more series by giving written notice thereof to the Company. If the instrument of acceptance by a successor Trustee required by Section 6.11 shall not have been delivered to the Trustee within thirty
(30) days after the giving of such notice of resignation, the resigning Trustee may petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such
series. 
 (c) The Trustee may be removed at any time with respect to the Securities of any series by Act of the Holders of a
majority in principal amount of the Outstanding Securities of such series, delivered to the Trustee and to the Company. If the instrument of acceptance by a successor Trustee required by Section 6.11 shall not have been delivered to the
Trustee within thirty (30) days after the giving of such notice of removal, the Trustee being removed may petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a successor Trustee with respect to
the Securities of such series. 
 (d) If at any time: 
 (1) the Trustee shall fail to comply with Section 6.8 after written request therefor by the Company or by any
Holder who has been a bona fide Holder of a Security for at least six months, or 
 (2) the Trustee ceases to be
eligible under Section 6.9 and shall fail to resign after written request therefor by the Company or by any such Holder, 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 Section 5.14, any Holder who has been a bona fide
Holder of a Security for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee with respect to all Securities and the appointment of a successor
Trustee or Trustees. 
 (e) If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur
in the office of Trustee for any cause, with respect to the Securities of one or more series, the Company, by or pursuant to a Board Resolution, shall promptly appoint a successor Trustee or Trustees with respect to the Securities of that or those
series (it being understood that any such successor Trustee may be appointed with respect to the Securities of one or more or all of such series and that at any time there shall be only one Trustee with respect to the Securities of any particular
series) and shall comply with the applicable requirements of Section 6.11. If within one year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee with respect to the Securities of any
series shall be appointed by Act of the Holders of a majority in principal amount of the Outstanding Securities of such series delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance
of such appointment in accordance with the applicable requirements of Section 6.11, become the successor Trustee with respect to the Securities of such series and to that extent supersede the successor Trustee appointed by the Company.
If no successor Trustee with respect to the Securities of any series shall have been so appointed by the Company or the Holders and accepted appointment in the manner required by Section 6.11, any Holder who has been a bona fide Holder
of a Security of such series for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series.

 (f) The Company shall give notice of each resignation and each removal of the Trustee with respect to the Securities of any
series and each appointment of a successor Trustee with respect to the Securities of any series to all Holders of Securities of such series in the manner provided in Section 1.8. Each notice shall include the name of the successor
Trustee with respect to the Securities of such series and the address of its Corporate Trust Office. 
 Section 6.11 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 so appointed shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become
effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on the request of the Company or the successor Trustee, such retiring
Trustee shall, upon payment of its charges, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all
property and money held by such retiring Trustee hereunder. 
  

 18 

 (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 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
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; provided, however, that to the extent that such property and money is not held by the Trustee in trust for the benefit of the Holders of particular
Securities, such retiring Trustee shall transfer and deliver to such successor Trustee such property and money upon payment of its charges hereunder. 
 (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) and (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 6.12 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 or banking association resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation or banking
association succeeding to all or substantially all the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such corporation or banking association 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 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 so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities; and in case at that time
any Securities 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 to the Trustee; and in all such cases such certificates
of authentication shall have the full force and effect which is otherwise provided for anywhere in the Securities or in this Indenture that a certificate of authentication of the Trustee would have. 
 Section 6.13 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). 
 Section 6.14 Investment of Certain Payments Held by the Trustee.

 Any amounts held by the Trustee hereunder, other than pursuant to Article 13 hereof, shall be invested by the
Trustee from time to time at the written direction of the Company in such investments as may be specified by the Company and permitted by law and under the Indenture; provided that in investing trust funds pursuant to the terms of this
Section and liquidating any investments held in trust hereunder, the Trustee may, to the extent permitted by law, purchase securities (including for the purposes of this paragraph securities as to which the Trustee or a Trustee Affiliate (as defined
below) is the issuer or guarantor) from, and sell securities to, itself or any Trustee Affiliate and purchase securities underwritten by, or in which a market is made by, the Trustee or a Trustee Affiliate. For the purposes hereof, a “
Trustee Affiliate ” shall mean an entity that directly, or indirectly through one or more intermediaries, controls, or is controlled by, or is under common control with, the Trustee. Any income or gain realized as a result of any such
investment shall be promptly distributed (in no event later than the next Business Day) to the Company after any intended amounts have been paid to the Holders entitled thereto, except after the occurrence and during the continuance of an Event of
Default. The Trustee shall have no liability to the Company for any loss resulting from any investment made in accordance with this Section, and shall bear no expense in connection with any investment pursuant to this Section. Any such investment
may be sold (without regard to maturity date) by the Trustee whenever necessary to make any distribution required by this Indenture. Nothing herein shall require the Trustee to invest funds held by it pursuant to the last paragraph of
Section 10.3. 
 Section 6.15 Appointment of Authenticating Agent. 
 (a) 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 original issue and upon exchange, registration of transfer or partial redemption thereof or pursuant to Section 3.6, 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. Wherever reference is made in this Indenture to the authentication and delivery of Securities by the
Trustee or the Trustee’s certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the
Trustee by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the Company and shall at all times be a corporation organized and doing business under the laws of the United States of America, any State thereof or the District
of Columbia, authorized under such laws to act as Authenticating Agent, having a combined capital and surplus of not less than $50,000,000 and subject to supervision or examination by federal or state authority. If such Authenticating Agent
publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Authenticating Agent shall be deemed
to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, such Authenticating Agent
shall resign immediately in the manner and with the effect specified in this Section. 
 (b) 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 all
or substantially all the corporate agency or corporate trust business of an Authenticating Agent, shall continue to be an Authenticating Agent provided such corporation shall be otherwise eligible under this Section, without the execution or filing
of any paper or any further act on the part of the Trustee or the Authenticating Agent. 
 (c) An Authenticating Agent may
resign at any time by giving written notice thereof to the Trustee and to the Company. The Trustee may at any time terminate

  

 19 

 
the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Company. Upon receiving such a notice of resignation or upon such a termination, or
in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent which shall be acceptable to the Company and shall mail written
notice of such appointment by first-class mail, postage prepaid, to all Holders of Securities of the series with respect to which such Authenticating Agent will serve, as their names and addresses appear in the Security Register. 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. No successor
Authenticating Agent shall be appointed unless eligible under the provisions of this Section. 
 (d) The Company agrees to pay
to each Authenticating Agent from time to time reasonable compensation for its services under this Section. 
 (e) 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 alternative certificate of
authentication in the following form: 
 This is one of the Securities of the series designated therein referred to in the
within-mentioned Indenture.

 The Company may also from time
to time designate one or more other offices or agencies where the Securities of one or more series may be presented or surrendered for any or all such purposes and may from time to time rescind 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 each Place of Payment for Securities of any series for such purposes. The Company will

  

 22 

 
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. 
 Section 10.3 Money for Securities Payments to Be Held in Trust. 
 If the Company shall at any time act as its own Paying Agent with respect to any series of Securities, it will, on or before each due date of the principal of (and premium, if any) or interest on any of
the Securities of that series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay the principal (and premium, if any) or interest so becoming due until such sums shall be paid to such Persons or
otherwise disposed of as herein provided and 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, it will, on or before each due date of the principal of (and premium, if any) or interest on any Securities of that series, deposit with a Paying Agent a sum sufficient
to pay the principal (and premium, if any) or interest so becoming due, such sum to be held in trust for the benefit of the Persons entitled to such principal, premium or interest, and (unless such Paying Agent is the Trustee) the Company will
promptly notify the Trustee of its action or failure so to act. 
 The Company will cause each Paying Agent for any series of
Securities other than the Trustee to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent will: 
 (1) hold all sums held by it for the payment of the principal of (and premium, if any) or interest on Securities of that
series 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 notice of any default by the Company (or any other obligor upon the Securities of that series) in the making of any payment of principal (and premium, if any) or interest on the
Securities of that series; 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. 
 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 Order of the Company direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent,
such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by the Company or such Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further
liability with respect to such money. 
 Any money deposited with the Trustee or any Paying Agent, or received by the Trustee in
respect of obligations deposited with the Trustee pursuant to Article 13, or then held by the Company, in trust for the payment of the principal of (and premium, if any) or interest on any Security of any series and remaining unclaimed for
two years after such principal (and premium, if any) or interest has become due and payable shall be paid to the Company on Request of the Company (unless otherwise required by mandatory provisions of applicable escheat or abandoned or unclaimed
property law), 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 thereof (unless the Company has remitted
required moneys or property to the appropriate governmental authority under any applicable escheat or abandoned or unclaimed property laws, or has otherwise been discharged under such laws or laws of similar applicability, in which case such Holder
shall look solely to its remedies (if any) under such laws and not to the Company), and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof shall thereupon cease;
provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in a newspaper published in the English language, customarily published on
each Business Day and of general circulation in the City of New York or mailed to Holders entitled to such notice, notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than thirty (30) days
from the date of such publication, any unclaimed balance of such money then remaining will be repaid to the Company. 
 Section 10.4
Corporate Existence. 
 Subject to Article 8, the Company will do or cause to be done all things necessary to preserve
and keep in full force and effect its corporate existence, rights (charter and statutory) and franchises; provided, however, that the Company shall not be required to preserve any such right or franchise if the Company shall determine that
the preservation thereof is no longer desirable in the conduct of the business of the Company. 
 Section 10.5 Waiver of Certain
Covenants. 
 Except as otherwise set forth in any supplemental indenture, the Company may omit in any particular instance to
comply with any covenant or condition set forth in Section 10.4 or in any supplemental indenture with respect to the Securities of any series, if before or after the time for such compliance the Holders of at least a majority in
principal amount of the Outstanding Securities of such series shall, 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 covenant or condition shall remain in full force
and effect. 
 The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Persons
entitled to waive compliance with any covenant or condition hereunder. If a record date is fixed, the Holders on such record date, or their duly designated proxies, and only such Persons, shall be entitled to waive any such compliance, whether or
not such Holders remain Holders after such record date. 
 Section 10.6 Compliance Certificate. 
 The Company will furnish to the Trustee, within 120 days after the end of each fiscal year of the Company ending after the date of the first
issuance of Securities of the applicable series, a brief certificate (which need not comply with Section 1.4) from the principal executive, financial or accounting Officer of the Company stating that in the course of the performance by
the signer of his or her duties as an Officer of the Company he or she would normally have knowledge of any default or non-compliance by the Company in the performance of any covenants or conditions contained in this Indenture or any supplemental
indenture with respect to such Securities, stating whether or not he or she has knowledge of any such default or non-compliance and, if so, specifying each such default or non-compliance of which the signer has knowledge and the nature thereof. For
purposes of this Section 10.6, non-compliance or default shall be determined without regard to any grace period or requirement of notice provided pursuant to the terms of this Indenture. 
 ARTICLE 11 
 REDEMPTION OF SECURITIES 
 Section 11.1 Applicability of Article. 
  

 23 

 Securities of any series which are redeemable in whole or in part before their Stated
Maturity shall be redeemable in accordance with their terms and (except as otherwise specified as contemplated by Section 3.1 for Securities of any series) in accordance with this Article. 
 Section 11.2 Election to Redeem; Notice to Trustee. 
 The election of the Company to redeem any Securities shall be evidenced by or pursuant to a Board Resolution or Officers’ Certificate. In case of any redemption at the election of the Company of the
Securities of any series, the Company shall, at least sixty (60) days prior to the Redemption Date fixed by the Company (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee of such Redemption Date, of the principal
amount of Securities of such series to be redeemed and, if applicable, of the tenor of the Securities to be redeemed. In the case of any redemption of Securities (1) prior to the expiration of any restriction on such redemption provided in the
terms of such Securities or elsewhere in this Indenture or (2) pursuant to an election of the Company which is subject to a condition specified in the terms of such Securities or elsewhere in this Indenture, the Company shall furnish the
Trustee with an Officers’ Certificate evidencing compliance with such restriction or condition. 
 Section 11.3 Selection of
Securities to Be Redeemed. 
 If less than all the Securities of any series are to be redeemed (unless all of the Securities
of such series and of a specified tenor are to be redeemed or unless such redemption affects only a single Security), the particular Securities to be redeemed shall be selected not more than sixty (60) days prior to the Redemption Date by the
Trustee, from the Outstanding Securities of such series not previously called for redemption, by (1) in such manner as complies with the requirements of the principal national securities exchange, if any, on which the Securities being redeemed
are listed, or (2) if the Securities are not then listed on a national securities exchange, then pro rata or by lot or (3) by such other method as the Trustee shall deem fair and appropriate and which may provide for the selection
for redemption of a portion of the principal amount of any Security of such series, provided that the unredeemed portion of the principal amount of any Security shall be in an authorized denomination (which shall not be less than the minimum
authorized denomination) for such Security. If less than all of the Securities of such series and of a specified tenor are to be redeemed (unless such redemption affects only a single Security), the particular Securities to be redeemed shall be
selected not more than sixty (60) days prior to the Redemption Date by the Trustee, from the Outstanding Securities of such series and specified tenor not previously called for redemption in accordance with the preceding sentence. 

The Trustee shall promptly notify the Company in writing of the Securities selected for redemption and, in the case of any Securities
selected for partial redemption, the principal amount thereof to be redeemed Securities and portions of Securities selected shall be in amounts of $1,000 or whole multiples of $1,000; except that if all of the Securities of a Holder are to be
redeemed, the entire Outstanding amount of Securities held by such Holder, even if not a multiple of $1,000, shall be redeemed. Except as provided in the preceding sentence, provisions of this Indenture that apply to Securities called for redemption
also apply to portions of Securities called for redemption.
 The provisions of the two preceding paragraphs shall not apply
with respect to any redemption affecting only a single Security, whether such Security is to be redeemed in whole or in part. In the case of any such redemption in part, the unredeemed portion of the principal amount of the Security shall be in an
authorized denomination (which shall not be less than the minimum authorized denomination) for such Security. 
 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 Securities redeemed or to be redeemed only in part, to the portion of the principal amount of
such Securities which has been or is to be redeemed. 
 Section 11.4 Notice of Redemption. 
 (a) Notice of redemption shall be given by first-class mail, postage prepaid, mailed not less than thirty (30) nor more than sixty
(60) days prior to the Redemption Date, to each Holder of Securities to be redeemed, at his address appearing in the Security Register. 
 (b) All notices of redemption shall identify the Securities to be redeemed (including CUSIP numbers, provided, however, that no representation will be made as to the correctness or accuracy of the
CUSIP number) and shall state: 
 (1) the Redemption Date, 
 (2) the Redemption Price (or the method of calculating such price), 
 (3) in the case of partial redemption of any Securities, the principal amounts of the particular Securities to be redeemed,

 (4) that on the Redemption Date the Redemption Price will become due and payable upon each such Security, or
portion thereof, to be redeemed and, if applicable, that interest thereon will cease to accrue on and after said date, 
 (5) for any Securities that by their terms may be converted, the terms of conversion, the date on which the right to convert the Security to be redeemed will terminate and the place or places where such Securities may be surrendered for
conversion; 
 (6) the place or places where such Securities are to be surrendered for payment of the Redemption
Price, and 
 (7) that the redemption is for a sinking fund, if such is the case. 
 (c) Notice of redemption of Securities to be redeemed at the election of the Company shall be given by the Company or, at the Company’s
request, by the Trustee in the name and at the expense of the Company and shall be irrevocable. The notice, if mailed in the manner provided herein, shall be conclusively presumed to have been given, whether or not the Holder receives such notice.
In any case, failure to give such notice by mail or any defect in the notice to the Holder of any Security designed for redemption as a whole or in part shall not affect the validity of the proceedings for the redemption of any other securities.

 Section 11.5 Deposit of Redemption Price. 
 On or prior to the Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in
Section 10.3) an amount of money in the currency or currencies in which the Securities of such series are payable (except as otherwise specified pursuant to Section 3.1 for the Securities of such series) sufficient to pay 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 11.6 Securities Payable on Redemption Date. 
 (a) Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified, and from and
after such date (unless the Company shall default in the payment of the Redemption Price and accrued interest) such Securities shall cease to bear interest. Upon surrender of any such Security for redemption in accordance with said notice, such
Security shall be paid by the Company at the

  

 24 

 
Redemption Price, together with accrued interest to the Redemption Date; provided, however, that, unless otherwise specified as contemplated by Section 3.1, installments of
interest whose Stated Maturity is on or prior to the Redemption Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the relevant Record Dates according to
their terms and the provisions of Section 3.7. 
 (b) If any Security called for redemption shall not be so paid
upon surrender thereof for redemption, the principal and any premium shall, until paid, bear interest from the Redemption Date at the rate prescribed therefor in the Security. 
 Section 11.7 Securities Redeemed in Part. 
 Any Security which is to be
redeemed only in part 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 or make available for delivery to the Holder of such Security without service charge, a new Security or
Securities of the same series and of like tenor, of any authorized denomination as requested by such Holder, in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Security so surrendered. If a
Book-Entry Security is so surrendered, such new Security so issued shall be a new Book-Entry Security. 
 ARTICLE 12

 REPURCHASE AT THE OPTION OF HOLDERS 
 Section 12.1 Applicability of Article. 
 Repurchase of Securities of
any series before their Stated Maturity at the option of Holders thereof shall be made in accordance with the terms of such Securities and (except as otherwise specified or as contemplated by Section 3.1 for Securities of any series) in
accordance with this Article. 
 Section 12.2 Repurchase of Securities. 
 Securities of any series subject to repurchase in whole or in part at the option of the Holders thereof will, unless otherwise provided in
the terms of such Securities, be repurchased at a price equal to the principal amount thereof and premium, if any, thereon, together with interest thereon accrued to the Repurchase Date specified in or pursuant to the terms, if any, of such
Securities. The Company covenants that on or before the Repurchase Date it will deposit with the Trustee or Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 10.3) an
amount of money sufficient to pay the principal (or, if so provided by the terms of the Securities of any series, a percentage of the principal) of, the premium, if any, and (except if the Repurchase Date shall be an Interest Payment Date) accrued
interest on, all the Securities or portions thereof, as the case may be, to be repurchased on such date, as required by any supplemental indenture. 
 Section 12.3 Exercise of Option. 
 Securities of any series subject to repurchase at the option of the
Holders thereof may contain an “Option to Elect Repurchase” form on the reverse of such Securities. In the case of Securities with the “Option to Elect Repurchase” form, such Securities to be repurchased at the option of the
Holder must have the “Option to Elect Repurchase” form duly completed by the Holder (or by the Holder’s attorney duly authorized in writing), and such completed form and Securities must be received by the Company at the Place of
Payment therefor specified in the terms of such Security (or at such other place or places of which the Company shall from time to time notify the Holders of such Securities) not earlier than 45 days nor later than 30 days prior to the Repurchase
Date. If less than the entire principal amount of such Security is to be repurchased in accordance with the terms of such Security, the principal amount of such Security to be repurchased, 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 repurchased, must be specified. The principal amount
of any Security providing for repurchase at the option of the Holder thereof may not be repurchased in part if, following such repurchase, the unpaid principal amount of such Security would be less than the minimum authorized denomination of
Securities of the series of which such Security to be repurchased is a part. Except as otherwise may be provided by the terms of any Security providing for repurchase at the option of the Holder thereof, exercise of the repurchase option by the
Holder shall be irrevocable unless waived by the Company. 
 Section 12.4 When Securities Presented for Repurchase Become Due and
Payable. 
 If Securities of any series providing for repurchase 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 repurchased shall become due and payable and shall be paid by the Company on
the Repurchase Date therein specified, and on and after such Repurchase Date (unless the Company shall default in the payment of such Securities on such Repurchase Date) such Securities shall, if the same were interest-bearing, cease to bear
interest. Upon surrender of any such Security for repurchase in accordance with such provisions, the principal amount of such Security so to be repurchased shall be paid by the Company, together with accrued interest and/or premium, if any, to (but
excluding) the Repurchase Date; provided, however, that, unless otherwise specified as contemplated by Section 3.1, installments of interest, if any, whose Stated Maturity is on or prior to the Repurchase 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 3.7. 
 If the principal amount of any Security surrendered for repurchase
shall not be so repurchased upon surrender thereof, such principal amount (together with interest, if any, thereon accrued to such Repurchase Date) and any premium shall, until paid, bear interest from the Repurchase Date at the rate of interest or
yield to Maturity (in the case of Original Issue Discount Securities) set forth in such Security. 
 Section 12.5 Securities Repurchased
in Part. 
 Upon surrender of any Security which is to be repurchased 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 Security or Securities of the same series, of any authorized denomination specified by the Holder, in a principal amount
equal to and in exchange for the portion of the principal of such Security so surrendered which is not to be repurchased. 
 ARTICLE 13 
 SINKING FUNDS 
  

 25 

 Section 13.1 Applicability of Article. 
 (a) 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 3.1 for Securities of such series. 
 (b) The minimum amount of any sinking
fund payment provided for by the terms of Securities of any series is herein referred a “mandatory sinking fund payment,” and any payment in excess of such minimum amount provided for by the terms of Securities of any series is herein
referred to as an “optional sinking fund payment”. If provided for by the terms of Securities of any series, the cash amount of any sinking fund payment may be subject to reduction as provided in Section 13.2. Each sinking fund
payment shall be applied to the redemption of Securities of any series as provided for by the terms of Securities of such series. 
 Section 13.2 Satisfaction of Sinking Fund Payments with Securities. 
 The Company (1) may deliver
Outstanding Securities of a series (other than any previously called for redemption) and (2) may apply as a credit Securities of a series which have been redeemed either at the election of the Company pursuant to the terms of such Securities or
through the application of permitted optional sinking fund payments pursuant to the terms of such Securities, in each case in satisfaction of all or any part of any sinking fund payment with respect to the Securities of such series required to be
made pursuant to the terms of such Securities as and to the extent provided for by the terms of such series; provided that such Securities have not been previously so credited. Such Securities shall be received and credited for such purpose
by the Trustee at the Redemption Price specified in such Securities for redemption through operation of the sinking fund and the amount of such sinking fund payment shall be reduced accordingly. 
 Section 13.3 Redemption of Securities for Sinking Fund. 
 Not less than forty-five (45) days prior to each sinking fund payment date for any series of Securities, the Company will deliver to the Trustee an Officers’ Certificate specifying the amount of
the next ensuing sinking fund payment for that series pursuant to the terms of that series, the portion thereof, if any, which is to be satisfied by payment of cash and the portion thereof, if any, which is to be satisfied by delivering and
crediting Securities of that series pursuant to Section 13.2 and stating the basis for such credit and that such Securities have not been previously so credited and will also deliver to the Trustee any Securities to be so delivered. Not
less than thirty (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 11.3 and cause notice of the
redemption thereof to be given in the name of and at the expense of the Company in the manner provided in Section 11.4. Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner
stated in Section 11.6 and Section 11.7. 
 ARTICLE 14 
 DEFEASANCE AND COVENANT DEFEASANCE 
 Section 14.1 Applicability of Article; Company’s Option to Effect Defeasance or Covenant Defeasance. 
 Unless, pursuant to Section 3.1, provision is made that either or both of (1) defeasance of the Securities of a series under Section 14.2 as may be specified pursuant to Section 3.1 with respect to
any Securities, shall be applicable or (2) covenant defeasance of the Securities of a series under Section 14.3 shall not apply to the Securities of a series, then the provisions of such Section or Sections, as the case may be,
together with the other provisions of this Article Thirteen, with such modifications thereto to the Securities of such series, and the Company may at its option by Board Resolution, at any time, with respect to the Securities of such series, elect
to have either Section 14.2 (if applicable) or Section 14.3 (if applicable) applied to the Outstanding Securities of such series upon compliance with the conditions set forth below in this Article 14. 
 Section 14.2 Defeasance and Discharge. 
 Upon the Company’s exercise of its option to have this Section applied to any series of Securities, the Company shall be deemed to have been discharged from its obligations with respect to the
Outstanding Securities of such series, and the provisions of Article 14 hereof shall cease to be effective, on and after the date the conditions precedent set forth below 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 the Outstanding Securities of such series which shall thereafter be deemed to be “Outstanding” only for the purposes
of the Sections of this Indenture referred to in clauses (1) and (2) of this Section, and to have satisfied all its other obligations under such Securities and this Indenture insofar as such Securities 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: (1) the rights of Holders of Outstanding Securities of such
series to receive, solely from the trust fund described in Section 14.4 as more fully set forth in such Section, payments of the principal of (and premium, if any) and interest on such Securities when such payments are due, (2) the
Company’s obligations with respect to such Securities under Section 3.5, Section 3.6, Section 10.2 and Section 10.3 and such obligations as shall be ancillary thereto, (3) the rights, powers,
trusts, duties, immunities and other provisions in respect of the Trustee hereunder and (4) this Article. Subject to compliance with this Article, the Company may exercise its option under this Section 14.2 notwithstanding the prior
exercise of its option under Section 14.3 with respect to the Securities of such series. Following a defeasance, payment of such Securities may not be accelerated because of an Event of Default. 
 Section 14.3 Covenant Defeasance. 
 Upon the Company’s exercise of its option (if any) to have this Section applied to any series of Securities, the Company shall be released from its obligations under Section 8.1,
Section 10.5 and Section 10.6 (and any covenant made applicable to such Securities pursuant to Section 3.1) and the occurrence of an event specified in Section 5.1(a)(4) (with respect to
Section 8.1, Section 10.5 and Section 10.6 or any such covenant) (and any other Event of Default applicable to such Securities that are determined pursuant to Section 3.1 to be subject to this
provision) shall not be deemed to be an Event of Default with respect to the Outstanding Securities of such series and the provisions of Article 14 hereof shall cease to be effective on and after the date the conditions set forth below are
satisfied (hereinafter, “covenant defeasance”), and such Securities shall thereafter be deemed not to be “Outstanding” for the purposes of any direction, waiver, consent or declaration or Act of Holders (and the consequences of
any other thereof) in connection with Section 8.1, Section 10.5 and Section 10.6 (and any other covenant made applicable to such Security pursuant to Section 3.1) and any such Events of Default, but
shall continue to be deemed “Outstanding” for all other purposes hereunder. For this purpose, such covenant defeasance means that, with respect to the Outstanding Securities of such series, 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 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 any reference in any such Section or such other covenant to any other provision herein or in any other document, but the remainder of this Indenture and such Securities shall be unaffected thereby. Notwithstanding the defeasance by the Company of
its obligations under Section 8.1, Section 10.5 and Section 10.6, any successor shall be required to assume the Company’s obligations under Section 6.7 as a condition to such succession.

 Section 14.4 Conditions to Defeasance or Covenant Defeasance. 
 The following shall be the conditions precedent to application of either Section 14.2 or Section 14.3 to the
Outstanding Securities of or within such series: 
  

 26 

 (1) The Company shall irrevocably have deposited or caused to be deposited
with the Trustee (or another trustee satisfying the requirements of Section 6.9 who shall agree to comply with the provisions of this Article 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, (A) money in an amount (in such currency, currencies or currency units in which such Securities are then specified as payable at
Maturity), or (B) U.S. Government Obligations 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, money in an
amount, or (C) a combination thereof in an amount, sufficient, without reinvestment, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, to pay
and discharge, and which shall be applied by the Trustee (or other qualifying trustee) to pay and discharge, (i) the principal of (and premium, if any) and interest on the Outstanding Securities of such series on the Maturity of such principal,
premium, if any, or interest and (ii) any mandatory sinking fund payments applicable to such Securities on the day on which such payments are due and payable in accordance with the terms of this Indenture and such Securities. Before such a
deposit the Company may make arrangements satisfactory to the Trustee for the redemption of Securities at a future date or dates in accordance with Article 11, which shall be given effect in applying the foregoing “U.S. Government
Obligations” means securities that are (x) direct obligations of the United States of America for the payment of which its full faith and credit is pledged or (y) obligations of a Person controlled or supervised by and acting as
an agency or instrumentality of the United States of America the payment of which is unconditionally guaranteed as a full faith and credit obligation by the United States of America, which, in either case, are not callable or redeemable at the
option of the issuer thereof, and shall also include a depositary receipt issued by a bank (as defined in Section 3(a)(2) of the Securities Act) as custodian with respect to any such U.S. Government Obligation or a specific payment of principal
of or interest on any such U.S. Government Obligation held by such custodian for the account of the holder of such depositary receipt, provided that (except as required by law) such custodian is not authorized to make any deduction from the
amount payable to the holder of such depositary receipt from any amount received by the custodian in respect of the U.S. Government Obligation or the specific payment of principal of or interest on the U.S. Government Obligation evidenced by such
depositary receipt. 
 (2) 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 of such series shall have occurred and be continuing (A) on the date of such deposit or (B) insofar as Section 5.1(a)(5) and Section 5.1(a)(6) are concerned, at any
time during the period ending on the 91st day after the date of such deposit or, if longer, ending on the day following the expiration of the longest preference period applicable to the Company in respect of such deposit (it being understood that
this condition shall not be deemed satisfied until the expiration of such period). 
 (3) Such defeasance or
covenant defeasance shall not (A) cause the Trustee for the Securities of such series to have a conflicting interest as defined in Section 6.8 or for purposes of the TIA with respect to any Securities of the Company or
(B) result in the trust arising from such deposit to constitute, unless it is qualified as, a regulated investment company under the Investment Company Act of 1940, as amended. 
 (4) Such defeasance or covenant defeasance shall not result in a breach or violation of or constitute a default under, this
Indenture or any other material agreement or instrument to which the Company is a party or by which it is bound. 
 (5) In the case of an election under Section 14.2, the Company shall have delivered to the Trustee an Opinion of Counsel stating that (A) the Company has received from, or there has been published by, the Internal Revenue
Service a ruling, or (B) since the date 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 the Outstanding
Securities of such series 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. 
 (6) In the case of an election under
Section 14.3, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of the Outstanding 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. 
 (7) Such defeasance or covenant defeasance shall be effected in compliance with any additional terms, conditions or
limitations which may be imposed on the Company in connection therewith pursuant to Section 3.1. 
 (8) The Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for relating to either the defeasance under Section 14.2 or the
covenant defeasance under Section 14.3 (as the case may be) have been complied with. 
 Section 14.5 Deposited Money and
U.S. Government Obligations to be Held in Trust; Other Miscellaneous Provisions. 
 Subject to the provisions of the last
paragraph of Section 10.3, all money and U.S. Government Obligations (including the proceeds thereof) deposited with the Trustee or other qualifying trustee (collectively, for purposes of this Section 14.5, the
“Trustee”) pursuant to Section 14.4 in respect of the Outstanding Securities of such series shall be held in trust and applied by the Trustee, in accordance with the provisions of such Securities and this Indenture, to the
payment, either directly or through any Paying Agent (but not including the Company acting as its own Paying Agent) as the Trustee may determine, to the Holders of such Securities, of all sums due and to become due thereon in respect of principal
(and premium, if any) and interest, but such money need not be segregated from other funds except to the extent required by law. Money so held in trust shall not be subject to the provisions of this Article. 
 The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the money or U.S.
Government Obligations deposited pursuant to Section 14.4 or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of Outstanding Securities;
provided that the Trustee shall be entitled to charge any such tax, fee or other charge to such Holder’s account. 
 Anything herein to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon Request of the Company any money or U.S. Government Obligations held by it as provided in Section 14.4 which
in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect an
equivalent defeasance or covenant defeasance, as the case may be with respect to such Securities. 
 Section 14.6 Reinstatement. 

 If the Trustee or the Paying Agent is unable to apply any money in accordance with this Article by reason of any order or
judgment or any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s obligations under the Securities of such series shall be revived and reinstated as though no deposit had
occurred pursuant to this Article until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 14.5; provided, however, that (a) if the Company makes any payment of principal
of (and premium, if any) or interest on any such Security following the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Securities to receive such payment from the money held by the Trustee or
the Paying Agent, and (b) unless otherwise required by any legal proceeding or any order or judgment of any court or governmental authority, the Trustee or Paying Agent shall immediately return all such money and U.S. Government Obligations to
the Company promptly after receiving a written request therefor at any time, if such reinstatement of the Company’s obligations has occurred and continues to be in effect. 
 Section 14.7 Qualifying Trustee. 
  

 27 

 Any trustee appointed pursuant to Section 14.4 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. 
 ARTICLE 15 
 IMMUNITY OF INCORPORATORS, STOCKHOLDERS, OFFICERS, DIRECTORS AND EMPLOYEES

                     of Dollars on

hereof is paid or made available for payment [if applicable, insert — and (to the extent that the payment of such interest shall be legally enforceable) at the rate of         % per annum on
any overdue principal and premium and on any overdue installment of interest]. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in such Indenture, be paid to the Person in whose name
this Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest, which shall be the
                     or
                     (whether or not a Business Day), as the case may be, next preceding such Interest Payment Date. Any such interest
not so punctually paid or duly provided for will forthwith cease to be payable to the Holder on such Regular Record Date and may either be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the
close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to Holders of Securities of this series not less than ten (10) days prior to such Special Record

fully provided in said Indenture].

this Security shall not bear interest except in the case of a default in payment of principal upon acceleration, upon redemption or at Stated Maturity and in such case the overdue principal of this Security shall bear interest at the rate of
% per annum (to the extent that the payment of such interest shall be legally enforceable), which shall accrue from the date of such default in payment to the date payment of such principal has been made or duly provided for. Interest on any
overdue principal shall be payable on demand. [Any such interest on any overdue principal that is not so paid on demand shall bear interest at the rate of         % per annum (to the extent that
the payment of such interest shall be legally enforceable), which shall accrue from the date of such demand for payment to the date payment of such interest has been made or duly provided for, and such interest shall also be payable on demand.]]

 Payment of the principal of (and premium, if any) and [if applicable, insert — any such] interest on this Security will
be made at the office or agency of the Company maintained for that purpose in such coin or currency of [the United States of America] as at the time of payment is legal tender for payment of public and private debts [if applicable, insert —;
provided, however, that at the option of the Company payment of interest may be made by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register or by wire transfer to an account maintained
by the Person entitled thereto as specified in the Security Register, provided, however such Person shall have given the Trustee written wire instructions at least five (5) Business Days prior to the applicable Interest Payment Date.]

provision.] 
 Reference is hereby made to the further provisions of this Security set forth on the reverse hereof, which
further provisions shall for all purposes have the same effect as if set forth at this place.
