Amended Severance Agreement, effective as of January 1, 2010

 Exhibit 10.1 
 POLYCOM, INC. 
 AMENDED SEVERANCE AGREEMENT 

 This Amended Severance Agreement (the “Agreement”) is made and entered into by and between Polycom, Inc., a
Delaware Corporation (the “Company”), and you, Robert C. Hagerty, effective as of January 1, 2010, and amends and restates the Amended Severance Agreement entered into as of December 19, 2008, which amended and restated the
Severance Agreement entered into as of May 20, 2008, which amended and restated the Severance Agreement entered into as of July 31, 2003 (the “Original Effective Date”), by you and the Company. For purposes of this Agreement, the
“Company” shall include any parent or subsidiary of the Company, unless the context clearly requires otherwise. 
 This Agreement is intended to strongly encourage you to remain with the Company by providing you with certain severance benefits in the event that your employment with the Company terminates under certain circumstances. This Agreement also
is intended to provide you with enhanced financial security in recognition of your past and future service to the Company. 
 1.
Eligibility for Severance Benefits. You will be entitled to the payments and benefits described in Section 2 only if both: (a) either (1) the Company terminates your employment for a reason other than Cause, death or
Disability, or (2) you voluntarily terminate your employment with the Company for Good Reason, and (b) you (1) sign and deliver to the Company a Release of Claims satisfactory to the Company within the period required by the Release
of Claims and in no event later than sixty (60) days following your termination, inclusive of any revocation period set forth in the Release of Claims, (2) do not subsequently revoke your signature on the Release of Claims, and
(3) comply with all of the terms of this Agreement, including (but not limited to) Section 7 regarding Non-Solicitation of Employees and Section 8 regarding Non-Competition. Notwithstanding the preceding, if your termination of
employment would qualify you for payments and benefits under your Amended Change of Control Severance Agreement with the Company dated December 19, 2008, you will receive none of the payments and benefits described in Section 2. Instead,
you will receive the payments and benefits to which you are entitled under your Change of Control Severance Agreement. 
 2.
Severance Benefits. If you meet the eligibility requirements described in Section 1, you will receive the following. 
 (a) Severance Payments. You will receive a lump sum severance payment equal to the sum of (i) two hundred percent (200%) of your annual base salary in effect immediately prior to the date of your termination of employment
(the “Termination Date”) and (ii) the product of two hundred percent (200%) of your target bonus percentage applicable in the year immediately prior to your Termination Date multiplied by your annual base salary in effect
immediately prior to the Termination Date. Subject to Section 2(e) below, if your employment ends on or before October 15 of a calendar year, your severance payment will be made within three (3) days after the Release of Claims
becomes effective and no longer is subject to revocation but on or before December 31 of that calendar year. If your employment ends after October 15 of a calendar year, your severance

 
payment will be made on the later of (1) the first payroll date in the calendar year next following the calendar year in which your employment has ended or (2) the first payroll date
following the date your Release of Claims becomes effective, subject to Section 2(e) below. 
 (b) Option
Exercisability. You will have one year following the Termination Date to exercise your Company stock option grant nos. 00000822 (dated July 23, 1999), NQ000822 (dated July 23, 1999), 00002008 (dated May 17, 2001), NQ002008 (dated
May 17, 2001) and any Company stock options granted to you after the Original Effective Date, but in each case only to the extent that such option is vested and unexpired on the Termination Date. Moreover, in no event may any such option be
exercised after the original maximum term of the option. Any options that are unvested on the Termination Date will be forfeited on that date. 
 (c) Other Benefits. You may continue your health, dental and vision benefits coverage under the Company’s group health plans for up to one year following the Termination Date or until you (and
your eligible dependents) become eligible for group insurance benefits from another employer or are no longer eligible to receive continuation coverage pursuant to COBRA, whichever comes first, but only if you elect continuation coverage under the
Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”), within the time period prescribed pursuant to COBRA. For the duration of the one-year coverage period, the Company will reimburse you for the COBRA premiums paid
by you (for coverage for yourself and your eligible dependents). COBRA reimbursements will be made by the Company to you consistent with the Company’s normal expense reimbursement policy, provided that you submit documentation to the Company
substantiating your payments for COBRA coverage. After the one-year coverage period, Company reimbursements will cease and you will be responsible for the payment of any COBRA premiums. The Company will not reimburse you for any taxable income
imputed to you because the Company has reimbursed you for your COBRA premiums (or those of your eligible dependents). 
 (d)
Accrued Wages and Paid-Time Off; Expenses. The Company will pay you: (1) any unpaid base salary due for periods prior to the Termination Date, (2) all of your accrued and unused paid-time off (“PTO”) through the
Termination Date, (3) following your submission of proper expense reports, the total unreimbursed amount of all expenses incurred by you in your duties of employment with the Company that are reimbursable in accordance with the Company’s
then-existing policies, and (4) any other benefits due to you through the Termination Date under the Company’s formal employee benefit plans (for example, the Company’s “401(k)” plan). These payments will be made promptly
upon your employment termination and within the period of time mandated by law or as provided in the applicable plan document. 
 (e) Section 409A. 
 (i) Six-Month Delay. Notwithstanding anything to the contrary in this
Agreement, no Deferred Compensation Separation Benefits (as defined below) payable under this Agreement will be considered due or payable until you have incurred a “separation from service” within the meaning of Section 409A of the
Internal Revenue Code of 1986, as amended and the final regulations and any guidance promulgated thereunder (together, “Section 409A”). In addition, if you are a “specified employee” within the meaning of Section 409A at the
time of your separation from service (other than due to death), then the severance benefits payable to you under this Agreement, if

  

 -2- 

 
any, and any other severance payments or separation benefits that may be considered deferred compensation under Section 409A (together, the “Deferred Compensation Separation
Benefits”) otherwise due to you on or within the six (6) month period following your separation from service will accrue during such six (6) month period and will become payable in a lump sum payment (less applicable withholding
taxes) on the date six (6) months and one (1) day following the date of your separation from service. All subsequent payments, if any, will be payable in accordance with the payment schedule applicable to each payment or benefit.
Notwithstanding anything herein to the contrary, if you die following your separation from service but prior to the six (6) month anniversary of your date of separation, then any payments delayed in accordance with this paragraph will be
payable in a lump sum (less applicable withholding taxes) to your estate as soon as administratively practicable after the date of your death and all other Deferred Compensation Separation Benefits will be payable in accordance with the payment
schedule applicable to each payment or benefit. 
 (ii) Amendments to this Agreement to Comply with Section 409A.
This provision is intended to comply with the requirements of Section 409A so that none of the severance payments and benefits to be provided hereunder will be subject to the additional tax imposed under Section 409A, and any ambiguities
herein will be interpreted to so comply. The Company and you agree to work together in good faith to consider amendments to this Agreement and to take such reasonable actions, which are necessary, appropriate or desirable to avoid imposition of any
additional tax or income recognition prior to actual payment to you under Section 409A. 
 3. Other Terminations of
Employment. If your employment with the Company is terminated by the Company for Cause, death or Disability, or if you voluntarily terminate your employment other than for Good Reason, you will not be entitled to receive any of the payments or
benefits described in Section 2 of this Agreement. However, you may be eligible for benefits under the Company’s severance and benefit plans and policies on the Termination Date. In addition, the Company will pay you: (1) any unpaid
base salary due for periods prior to the Termination Date, (2) all of your accrued and unused PTO through the Termination Date, (3) following your submission of proper expense reports, the total unreimbursed amount of all expenses incurred
by you in your duties of employment with the Company that are reimbursable in accordance with the Company’s then-existing policies, and (4) any other benefits due to you through the Termination Date under the Company’s formal employee
benefit plans (for example, the Company’s “401(k)” plan). These payments will be made promptly upon your employment termination and within the period of time mandated by law or as provided in the applicable plan document. 

4. Definition of Terms. The following terms used to in this Agreement shall have the following meanings: 
 (a) Cause. “Cause” means (1) an act of personal dishonesty taken by you in connection with your responsibilities as an
employee and intended to result in your substantial personal enrichment, (2) your being convicted of a crime recognized as a felony in the United States, (3) a willful act by you which constitutes gross misconduct and which is injurious to
the Company, (4) following delivery to you of a written demand for performance from the Company which describes the basis for the Company’s reasonable belief that the you have not substantially performed your duties, continued violations
by you of your obligations to the Company which are demonstrably willful and deliberate on your part. 
  

 -3- 

 (b) Disability. “Disability” means your being unable to perform the
principal functions of your duties due to a physical or mental impairment, but only if such inability has lasted or is reasonably expected to last for at least six months. The Company will determine whether a Disability exists based on evidence
provided by one or more physicians selected by the Company and reasonably acceptable to you. 
 (c) Good Reason.
“Good Reason” means, without your written consent (1) a material reduction of your duties, authority or responsibilities, relative to your duties, authority or responsibilities as in effect immediately prior to such reduction, or the
assignment to you of such reduced duties, authority or responsibilities; (2) a substantial reduction of the facilities and perquisites (including office space and location) available to you immediately prior to such reduction; (3) a
reduction by the Company of your base compensation or target annual bonus opportunity as in effect immediately prior to such reduction; (4) a material reduction by the Company in the kind or level of benefits to which you were entitled
immediately prior to such reduction with the result that your overall benefits are significantly reduced (unless similar reductions apply to substantially all of the Company’s other senior executives); (5) your relocation to a facility or
a location more than thirty-five (35) miles from your then present location. 
 (d) Release of Claims. “Release

 5. Term of Agreement. If you have a termination of employment that entitles you to receive the payments and benefits described in
Section 2, this Agreement will terminate when all of your and the Company’s obligations under the Agreement have been satisfied. If you have a termination of employment that does not entitle you to receive the payments and benefits
descried in Section 2, this Agreement will terminate on the Termination Date. 
 6. At-Will Employment. The Company
and you acknowledge that your employment is and will continue to be at-will, as defined under applicable law. 
 7.

employment, or take away such employees, or attempt to solicit, induce, recruit, encourage or take away employees of the Company, either for yourself or any other person or entity. 
 8. Non-Competition. With respect to any businesses of the Company or any of its subsidiaries during the period beginning on the
Original Effective Date through the date of your termination of employment from the Company and all of its subsidiaries (collectively, the “Businesses”), you agree that during the period beginning on the Original Effective Date and ending
two years after the date on which you terminate employment, you, directly or indirectly, whether as employee, owner, sole proprietor, partner, director, member, consultant, agent, founder, co-venturer or otherwise, will: (i) not engage,
participate or invest in any business activity anywhere in the world that is directly competitive with the principal products or services of the Businesses (except that it will not be a violation of this Section 8 for you to own as a passive
investment not more than one percent of any class of publicly traded securities of any entity); nor (ii) directly or indirectly solicit business from any of the Businesses’ customers and users on behalf of any business that directly
competes with the Businesses. 
  

 -4- 

 9. Assignment. This Agreement will be binding upon and become of advantage to
(a) your heirs, executors and legal representatives upon your death and (b) any successor of the Company. Any such successor of the Company will be deemed substituted for the Company under the terms of this Agreement for all purposes. For
this purpose, “successor” means any person, firm, corporation or other business entity which at any time, whether by purchase, merger or otherwise, directly or indirectly acquires all or substantially all of the assets or business of the
Company. None of your rights to receive any form of compensation payable pursuant to this Agreement may be assigned or transferred except by will or the laws of descent and distribution. Any other attempted assignment, transfer, conveyance or other
disposition of your right to compensation or other benefits will be null and void. 
 10. Notices.

 (b) Notice of Termination. Any termination by the Company for
Cause or by you for Good Reason must be communicated by a notice of termination to the other party. The notice will indicate the specific termination provision in this Agreement relied upon, will set forth in reasonable detail the facts and
circumstances claimed to provide a basis for termination under the provision so indicated, and will specify the date of your employment termination (which will not be more than 30 days after the giving of such notice). Any failure on your part to
include in the notice any fact or circumstance that contributes to a showing of Good Reason will not waive any of your rights under this Agreement or prevent you from asserting that fact or circumstance in enforcing this Agreement. 
  

 -5- 

 11. Severability. In the event that any provision hereof becomes or is declared by a
court of competent jurisdiction to be illegal, unenforceable or void, this Agreement will continue in full force and effect without said provision. 
 12. Entire Agreement. This Agreement, your Change of Control Severance Agreement and the agreements evidencing any Company stock options and other equity compensation awards (if any) granted to you
represent the entire agreement and understanding between the Company and you concerning your severance arrangements with the Company or any of its subsidiaries, and supersedes and replaces any and all prior agreements and understandings concerning
your severance arrangements with the Company. With respect to equity compensation awards granted on or after the date hereof, the acceleration of vesting provided therein will apply to such awards except to the extent otherwise explicitly provided
in the applicable equity award agreement. 
 13. Arbitration. 
 (a) General. In consideration of your service to the Company, its promise to arbitrate all employment related disputes and your
receipt of the compensation, pay raises and other benefits paid to you by the Company, at present and in the future, you agree that any and all controversies, claims, or disputes with anyone (including the Company and any employee, officer,
director, shareholder or benefit plan of the Company in their capacity as such or otherwise) arising out of, relating to, or resulting from your service to the Company under this Agreement or otherwise or the termination of your service with the
Company, including any breach of this Agreement, shall be subject to binding arbitration under the Arbitration Rules set forth in California Code of Civil Procedure Section 1280 through 1294.2, including Section 1283.05 (the
“Rules”) and pursuant to California law. Disputes which you agree to arbitrate, and thereby agree to waive any right to a trial by jury, include any statutory claims under state or federal law, including, but not limited to, claims under
Title VII of the Civil Rights Act of 1964, the Americans with Disabilities Act of 1990, the Age Discrimination in Employment Act of 1967, the Older Workers Benefit Protection Act, the California Fair Employment and Housing Act, the California Labor
Code, claims of harassment, discrimination or wrongful termination and any statutory claims. You further understand that this Agreement to arbitrate also applies to any disputes that the Company may have with you. 
 (b) Procedure. You agree that any arbitration will be administered by the American Arbitration Association (“AAA”) and that
a neutral arbitrator will be selected in a manner consistent with its National Rules for the Resolution of Employment Disputes. The arbitration proceedings will allow for discovery according to the rules set forth in the National Rules for the
Resolution of Employment Disputes or California Code of Civil Procedure. You agree that the arbitrator shall have the power to decide any motions brought by any party to the arbitration, including motions for summary judgment and/or adjudication and
motions to dismiss and demurrers, prior to any arbitration hearing. You agree that the arbitrator shall issue a written decision on the merits. You also agree that the arbitrator shall have the power to award any remedies, including attorneys’
fees and costs, available under applicable law. You understand the Company will pay for any administrative or hearing fees charged by the arbitrator or AAA except that you shall pay the first $200.00 of any filing fees associated with any
arbitration you initiate. You agree that the arbitrator shall administer and conduct any arbitration in a manner consistent with the Rules and that to the extent that the AAA’s National Rules for the Resolution of Employment Disputes conflict
with the Rules, the Rules shall take precedence. 
  

 -6- 

 (c) Remedy. Except as provided by the Rules, arbitration shall be the sole, exclusive
and final remedy for any dispute between you and the Company. Accordingly, except as provided for by the Rules, neither you nor the Company will be permitted to pursue court action regarding claims that are subject to arbitration. Notwithstanding,
the arbitrator will not have the authority to disregard or refuse to enforce any lawful Company policy, and the arbitrator shall not order or require the Company to adopt a policy not otherwise required by law which the Company has not adopted.

 (d) Availability of Injunctive Relief. In addition to the right under the Rules to petition the court for provisional
relief, you agree that any party may also petition the court for injunctive relief where either party alleges or claims a violation of this Agreement or any other agreement regarding trade secrets, confidential information, nonsolicitation or Labor
Code §2870. In the event either party seeks injunctive relief, the prevailing party shall be entitled to recover reasonable costs and attorneys’ fees. 
 (e) Administrative Relief. You understand that this Agreement does not prohibit you from pursuing an administrative claim with a local, state or federal administrative body such as the Department
of Fair Employment and Housing, the Equal Employment Opportunity Commission or the workers’ compensation board. This Agreement does, however, preclude you from pursuing court action regarding any such claim. 
 (f) Voluntary Nature of Agreement. You acknowledge and agree that you are executing this Agreement voluntarily and without any duress
or undue influence by the Company or anyone else. You further acknowledge and agree that you have carefully read this Agreement and that you have asked any questions needed for you to understand the terms, consequences and binding effect of this
Agreement and fully understand it, including that you are waiving your right to a jury trial. Finally, you agree that you have been provided an opportunity to seek the advice of an attorney of your choice before signing this Agreement. 

14. No Oral Modification, Cancellation or Discharge. This Agreement may be changed or terminated only in writing (signed by you
and an authorized officer of the Company). 
 15. Withholding. The Company is authorized to withhold, or cause to be
withheld, from any payment or benefit under this Agreement the full amount of any applicable withholding taxes. 
 16.
Governing Law. This Agreement will be governed by the laws of the State of California (with the exception of its conflict of laws provisions). 
 17. Acknowledgment. You acknowledge that you have had the opportunity to discuss this matter with and obtain advice from your private attorney, have had sufficient time to, and have carefully read
and fully understand all the provisions of this Agreement, and are knowingly and voluntarily entering into this Agreement.

direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by Holders of Securities of all series or one or more series, as the case may be, may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by agents duly appointed in writing. If Securities of a series are issuable as Bearer Securities, any request, demand, authorization, direction, notice, consent, waiver or other action
provided by this Indenture to be given or taken by Holders of Securities of such series may, alternatively, be embodied in and evidenced by the record of Holders of Securities of such series voting in favor thereof, either in person or by proxies
duly appointed in writing, at any meeting of Holders of Securities of such series duly called and held, or a combination of such instruments and any such record. Except as herein otherwise expressly provided, such action shall become effective when
such instrument or instruments or record or both are delivered to the Trustee and, where it is hereby expressly required, to the Company. Such instrument or instruments and any such record (and the action embodied therein and evidenced thereby) are
herein sometimes referred to as the “Act” of the Holders signing such instrument or instruments or so voting at any such meeting. Proof of execution of any such instrument or of a writing appointing any such agent, or of the holding by any
Person of a Security, shall be sufficient for any purpose of this Indenture and conclusive in favor of the Trustee and the Company and any agent of the Trustee or 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 or her 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 that the Trustee deems reasonably sufficient.

 (c) The ownership of Registered Securities shall be proved by the Security Register.

 (d) The ownership of Bearer Securities may be proved by the production of such Bearer Securities or by a certificate
executed, as depositary, by any trust company, bank, banker or other depositary, wherever situated, if such certificate shall be deemed by the Trustee to be satisfactory, showing that at the date therein mentioned such Person had on deposit with
such depositary, or exhibited to it, the Bearer Securities therein described; or such facts may be proved by the certificate or affidavit of the Person holding such Bearer Securities, if such certificate or affidavit is deemed by the Trustee to be
satisfactory. The Trustee and the Company may assume that such ownership of any Bearer Security continues until (1) another certificate or affidavit bearing a later date issued in respect of the same Bearer Security is produced, or
(2) such Bearer Security is produced to the Trustee by some other Person, or (3) such Bearer Security is surrendered in exchange for a Registered Security or (4) such Bearer Security is no longer Outstanding. The ownership of Bearer
Securities may also be proved in any other manner that the Trustee deems reasonably sufficient. 
 (e) If the Company shall
solicit from the Holders of Securities any request, demand, authorization, direction, notice, consent, waiver or other Act, the Company may, at its option, in or pursuant to a Board Resolution, fix in advance a record date for the determination of
Holders entitled to give such request, demand, authorization, direction, notice, consent, waiver or other Act, but the Company shall have no obligation to do so. Notwithstanding TIA Section 316(c), such record date shall be the record date
specified in or pursuant to such Board Resolution, which shall be a date not earlier than the date 30 days prior to the first solicitation of Holders generally in connection therewith and not later than the date such solicitation is completed. If
such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other Act may be given before or after such record date, but only the Holders of record at the close of business on such record date shall be
deemed to be Holders for the purposes of determining whether Holders of the requisite proportion of Outstanding Securities have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other
Act, and for that purpose the Outstanding Securities shall be computed as of such record date; provided that no such authorization, agreement or consent by the Holders on such record date shall be deemed effective unless it shall become
effective pursuant to the provisions of this Indenture not later than six months after the record date. 
 (f) Any request,
demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Security shall bind every future Holder of the same Security and the Holder of every Security issued upon the registration of transfer thereof or in exchange
therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee, any Security Registrar, any Paying Agent, any Authenticating Agent or the Company in reliance thereon, whether or not notation of such action is
made upon such Security. 
 Section 1.05. Notices, Etc., to Trustee and Company.

date, and not earlier than the earliest date, prescribed for the giving of such notice. In any case where notice to Holders of Registered Securities is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed,
to any particular Holder shall affect the sufficiency of such notice with respect to other Holders of Registered Securities or the sufficiency of any notice to Holders of Bearer Securities given as provided herein. Any notice mailed to a Holder in
the manner herein prescribed shall be conclusively deemed to have been received by such Holder, whether or not such Holder actually receives such notice. 
 If by reason of the suspension of or irregularities in regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such notification to Holders of
Registered Securities as shall be made with the approval of the Trustee shall constitute a sufficient notification to such Holders for every purpose hereunder. 
 Except as otherwise expressly provided herein or otherwise specified with respect to any Securities pursuant to Section 3.01, where this Indenture provides for notice to Holders of Bearer Securities
of any event, such notice shall be sufficiently given if published in an Authorized Newspaper in The City of New York and in such other city or cities as may be specified in such Securities on a Business Day, such publication to be not later than
the latest date, and not earlier than the earliest date, prescribed for the giving of such notice. Any such notice shall be deemed to have been given on the date of such publication or, if published more than once, on the date of the first such
publication. 
 If by reason of the suspension of publication of any Authorized Newspaper or Authorized Newspapers or by reason
of any other cause it shall be impracticable to publish any notice to Holders of Bearer Securities as provided above, then such notification to Holders of Bearer Securities as shall be given with the approval of the Trustee shall constitute
sufficient notice to such Holders for every purpose hereunder. Neither the failure to give notice by publication to Holders of Bearer Securities as provided above, nor any defect in any notice so published, shall affect the sufficiency of such
notice with respect to other Holders of Bearer Securities or the sufficiency of any notice to Holders of Registered Securities given as provided herein.

Table of Contents

 All Securities of any one series and the coupons appertaining to any Bearer Securities of
such series shall be substantially identical except, in the case of Registered Securities, as to denomination and except as may otherwise be provided in or pursuant to the Board Resolution referred to above (subject to Section 3.03) and set
forth in the Officers’ Certificate referred to above or in any such indenture supplemental hereto. All Securities of any one series need not be issued at the same time and, unless otherwise provided, a series may be reopened, without the
consent of the Holders, for issuances of additional Securities of such series. 
 If any of the terms of the Securities of any
series are established by action taken pursuant to one or more Board Resolutions, a copy of an appropriate record of such action(s) shall be certified by the Secretary or an Assistant Secretary of the Company and delivered to the Trustee at or prior
to the delivery of the Officers’ Certificate setting forth the terms of the Securities of such series. 
 Section 3.02.
Denominations. 
 The Securities of each series shall be issuable in such denominations as shall be specified as
contemplated by Section 3.01. With respect to Securities of any series denominated in Dollars, in the absence of any such provisions with respect to the Securities of any series, the Registered Securities of such series, other than Registered
Securities issued in global form (which may be of any denomination) shall be issuable in denominations of $1,000 and any integral multiple thereof, and the Bearer Securities of such series, other than Bearer Securities issued in global form (which
may be of any denomination), shall be issuable in a denomination of $5,000. 
 Section 3.03. Execution, Authentication,
Delivery and Dating. 
 The Securities and any coupons appertaining thereto shall be executed on behalf of the Company by
any one of its Chairman of the Board of Directors, its Chief Executive Officer, its President, its Chief Financial Officer or a Vice President and by one of its Secretary or its Controller, under its corporate seal reproduced thereon, and attested
by its Secretary or one of its Assistant Secretaries. The signature of any of these officers on the Securities and coupons may be manual or facsimile signatures of the present or any future such authorized officer and may be imprinted or otherwise
reproduced on the Securities. 
 Securities or coupons bearing the manual or facsimile signatures of individuals who were at any
time the proper officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at the
date of such Securities or coupons. 
 At any time and from time to time after the execution and delivery of this Indenture, the
Company may deliver Securities of any series, together with any coupon appertaining thereto, executed by the Company, to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Securities, and the
Trustee in accordance with the Company Order shall authenticate and deliver such Securities; provided, however, that, in connection with its original issuance, no Bearer Security shall be mailed or otherwise delivered to any location
in the United States; and provided further that, unless otherwise specified with respect to any series of Securities pursuant to Section 3.01, a Bearer Security may be delivered in

  

 22 

Table of Contents

 
connection with its original issuance only if the Person entitled to receive such Bearer Security shall have furnished a certificate in the form set forth in such certificate as may be specified
with respect to any series of Securities pursuant to Section 3.01, dated no earlier than 15 days prior to the earlier of the date on which such Bearer Security is delivered and the date on which any temporary Security first becomes exchangeable
for such Bearer Security in accordance with the terms of such temporary Security and this Indenture. If any Security shall be represented by a permanent global Bearer Security, then, for purposes of this Section and Section 3.04, the notation
of a beneficial owner’s interest therein upon original issuance of such Security or upon exchange of a portion of a temporary global Security shall be deemed to be delivery in connection with its original issuance of such beneficial
owner’s interest in such permanent global Security. Except as permitted by Section 3.06, the Trustee shall not authenticate and deliver any Bearer Security unless all appurtenant coupons for interest then matured have been detached and
cancelled. If all the Securities of any series are not to be issued at one time and if the Board Resolution or supplemental indenture establishing such series shall so permit, such Company Order may set forth procedures acceptable to the Trustee for
the issuance of such Securities and determining the terms of particular Securities of such series, such as interest rate, maturity date, date of issuance and date from which interest shall accrue. In authenticating such Securities, and accepting the
additional responsibilities under this Indenture in relation to such Securities, the Trustee shall be entitled to receive, and (subject to TIA Section 315(a) through 315(d)) shall be fully protected in relying upon, 
 (i) an Opinion of Counsel stating, 
 (a) that the form or forms of such Securities and any coupons have been established in conformity with the provisions of this
Indenture; 
 (b) that the terms of such Securities and any coupons have been established in conformity with the
provisions of this Indenture; and 
 (c) that such Securities, together with any coupons appertaining thereto,
when completed by appropriate insertions and executed and delivered by the Company to the Trustee for authentication in accordance with this Indenture, authenticated and delivered by the Trustee in accordance with this Indenture and issued by the
Company in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute legal, valid and binding obligations of the Company, enforceable in accordance with their terms, subject to applicable bankruptcy, insolvency,
reorganization and other similar laws of general applicability relating to or affecting the enforcement of creditors’ rights, to general equitable principles and to such other qualifications as such counsel shall conclude do not materially
affect the rights of Holders of such Securities and any coupons; and 
 (ii) an Officers’ Certificate
stating, to the knowledge of the signers of such certificate, that no Event of Default with respect to any of the Securities shall have occurred and be continuing.

Table of Contents

 Notwithstanding the provisions of Section 3.01 and of this Section 3.03, if all
the Securities of any series are not to be issued at one time, it shall not be necessary to deliver an Officers’ Certificate otherwise required pursuant to Section 3.01 or the Company Order, Opinion of Counsel or Officers’ Certificate
otherwise required pursuant to the preceding paragraph at the time of issuance of each Security of such series, but such order, opinion and certificates, with appropriate modifications to cover such future issuances, shall be delivered at or before
the time of issuance of the first Security of such series. 
 If such form 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 affect the Trustee’s own rights, duties, obligations or immunities under the Securities and this Indenture or otherwise in a manner
which is not reasonably acceptable to the Trustee. Notwithstanding the generality of the foregoing, the Trustee will not be required to authenticate Securities denominated in a Foreign Currency if the Trustee reasonably believes that it would be
unable to perform its duties with respect to such Securities. 
 Each Registered Security shall be dated the date of its
authentication and each Bearer Security shall be dated as of the date specified as contemplated by Section 3.01. 
 No
Security or coupon shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Security or Security to which such coupon appertains a certificate of authentication substantially in the
form provided for herein duly executed by the Trustee or an Authenticating Agent by manual signature of an authorized signatory, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been
duly authenticated and delivered hereunder and is entitled to the benefits of this Indenture. Notwithstanding the foregoing, if any Security shall have been authenticated and delivered hereunder but never issued and sold by the Company, and the
Company shall deliver such Security to the Trustee for cancellation as provided in Section 3.10 together with a written statement (which need not comply with Section 1.02 and need not be accompanied by an Opinion of Counsel) stating that
such Security has never been issued and sold by the Company, for all purposes of this Indenture such Security shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits of this Indenture.

 Section 3.04. Temporary Securities. 
 (a) Pending the preparation of definitive Securities of any series, the Company may execute, and upon Company Order the Trustee shall authenticate and deliver, temporary Securities which are printed,
lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued, in registered form, or, if authorized, in bearer form with one
or more coupons or without coupons, and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may determine, as conclusively evidenced by their execution of such Securities. In the
case of Securities of any series, such temporary Securities may be in global form. 
  

 24 

Table of Contents

 Except in the case of temporary Securities in global form (which shall be exchanged in
accordance with Section 3.04(b) or as otherwise provided in or pursuant to a Board Resolution), if temporary Securities of any series are issued, the Company will cause definitive Securities of that series to be prepared without unreasonable
delay. After the preparation of definitive Securities of such series, the temporary Securities of such series shall be exchangeable for definitive Securities of such series upon surrender of the temporary Securities of such series at the office or
agency of the Company in a Place of Payment for that series, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities of any series (accompanied by any non-matured coupons appertaining thereto), the
Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a like principal amount and like tenor of definitive Securities of the same series of authorized denominations; provided, however, that no
definitive Bearer Security shall be delivered in exchange for a temporary Registered Security; and provided further that a definitive Bearer Security shall be delivered in exchange for a temporary Bearer Security only in compliance with the
conditions set forth in Section 3.03. Until so exchanged, the temporary Securities of any series shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of such series. 
 (b) Unless otherwise provided in or pursuant to a Board Resolution, this Section 3.04(b) shall govern the exchange of temporary
Securities issued in global form through the London office of a depositary or common depositary (the “Common Depositary”), for the benefit of Euroclear and Clearstream, for credit to the respective accounts of the beneficial owners
of such Securities (or to such other accounts as they may direct). If temporary Securities of any series are issued in global form, any such temporary global Security shall, unless otherwise provided therein, be delivered to the London office of the
Common Depositary, for the benefit of Euroclear and Clearstream, for credit to the respective accounts of the beneficial owners of such Securities (or to such other accounts as they may direct). 
 Without unnecessary delay but in any event not later than the date specified in, or determined pursuant to the terms of, any such temporary
global Security (the “Exchange Date”), the Company shall deliver to the Trustee definitive Securities, in aggregate principal amount equal to the principal amount of such temporary global Security, executed by the Company. On or
after the Exchange Date, such temporary global Security shall be surrendered by the Common Depositary to the Trustee, as the Company’s agent for such purpose, or to the Security Registrar, to be exchanged, in whole or from time to time in part,
for definitive Securities without charge, and the Trustee shall authenticate and deliver, in exchange for each portion of such temporary global Security, an equal aggregate principal amount of definitive Securities of the same series of authorized
denominations and of like tenor as the portion of such temporary global Security to be exchanged. The definitive Securities to be delivered in exchange for any such temporary global Security shall be in bearer form, registered form, permanent global
bearer form or permanent global registered form, or any combination thereof, as specified as contemplated by Section 3.01, and, if any combination thereof is so specified, as requested by the beneficial owner thereof; provided,
however, that, unless otherwise specified in such temporary global Security, upon such presentation by the Common Depositary, such temporary global Security is accompanied by a certificate dated the Exchange Date or a subsequent date and
signed by Euroclear as to the portion of such temporary global Security held for its account then to be exchanged and a certificate dated the Exchange Date or a subsequent date and signed by Clearstream as to the portion of such temporary global
Security held for its account then to be exchanged, each in the

  

 25 

Table of Contents

 
form as may be established pursuant to Section 3.01; and provided further that definitive Bearer Securities shall be delivered in exchange for a portion of a temporary global Security
only in compliance with the requirements of Section 3.03. 
 Unless otherwise specified in such temporary global Security,
the interest of a beneficial owner of Securities of a series in a temporary global Security shall be exchanged for definitive Securities of the same series and of like tenor following the Exchange Date when the account holder instructs Euroclear or
Clearstream, as the case may be, to request such exchange on his behalf and delivers to Euroclear or Clearstream, as the case may be, a certificate in such form as may be established pursuant to Section 3.01, dated no earlier than 15 days prior
to the Exchange Date, copies of which certificate shall be available from the offices of Euroclear and Clearstream, the Trustee, any Authenticating Agent appointed for such series of Securities and each Paying Agent. Unless otherwise specified in
such temporary global Security, any such exchange shall be made free of charge to the beneficial owners of such temporary global Security, except that a Person receiving definitive Securities must bear the cost of insurance, postage, transportation
and the like unless such Person takes delivery of such definitive Securities in person at the offices of Euroclear or Clearstream. Definitive Securities in bearer form to be delivered in exchange for any portion of a temporary global Security shall
be delivered only outside the United States. 
 Until exchanged in full as hereinabove provided, the temporary Securities of any
series shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of the same series and of like tenor authenticated and delivered hereunder, except that, unless otherwise specified as contemplated by
Section 3.01, interest payable on a temporary global Security on an Interest Payment Date for Securities of such series occurring prior to the applicable Exchange Date shall be payable to Euroclear and Clearstream on such Interest Payment Date
upon delivery by Euroclear and Clearstream to the Trustee or the applicable Paying Agent of a certificate or certificates in the form as may be established pursuant to Section 3.01 for credit without further interest on or after such Interest
Payment Date to the respective accounts of Persons who are the beneficial owners of such temporary global Security on such Interest Payment Date and who have each delivered to Euroclear or Clearstream, as the case may be, a certificate dated no
earlier than 15 days prior to the Interest Payment Date occurring prior to such Exchange Date in the form as may be established pursuant to Section 3.01. Notwithstanding anything to the contrary herein contained, the certifications made
pursuant to this paragraph shall satisfy the certification requirements of the preceding two paragraphs of this Section 3.04(b) and of the third paragraph of Section 3.03 of this Indenture and the interests of the Persons who are the
beneficial owners of the temporary global Security with respect to which such certification was made will be exchanged for definitive Securities of the same series and of like tenor on the Exchange Date or the date of certification if such date
occurs after the Exchange Date, without further act or deed by such beneficial owners. Except as otherwise provided in this paragraph, no payments of principal (or premium, if any) or interest, if any, owing with respect to a beneficial interest in
a temporary global Security will be made unless and until such interest in such temporary global Security shall have been exchanged for an interest in a definitive Security. Any interest so received by Euroclear and Clearstream and not paid as
herein provided shall be returned to the Trustee or the applicable Paying Agent immediately prior to the expiration of two years after such Interest Payment Date in order to be repaid to the Company.

 Section 3.05. Registration, Transfer and Exchange. 
 The Company shall cause to be kept at the Corporate Trust Office of the Trustee or in any office or agency of the Company in a Place of
Payment a register for each series of Securities (the registers maintained in such office or in any such office or agency of the Company in a Place of Payment being herein sometimes referred to collectively as the “Security
Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Registered Securities and of transfers of Registered Securities. The Security Register shall be in written
form or any other form capable of being converted into written form within a reasonable time. The Trustee, at its Corporate Trust Office, is hereby initially appointed “Security Registrar” for the purpose of registering Registered
Securities and transfers of Registered Securities on such Security Register as herein provided, and for facilitating exchanges of temporary global Securities for permanent global Securities or definitive Securities, or both, or of permanent global
Securities for definitive Securities, or both, as herein provided. In the event that the Trustee shall cease to be Security Registrar, it shall have the right to examine the Security Register at all reasonable times. 
 Upon surrender for registration of transfer of any Registered Security of any series at any office or agency of the Company in a Place of
Payment for that series, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Registered Securities of the same series, of any authorized denominations
and of a like aggregate principal amount, bearing a number not contemporaneously outstanding and containing identical terms and provisions. 
 At the option of the Holder, Registered Securities of any series may be exchanged for other Registered Securities of the same series, of any authorized denomination or denominations and of a like
aggregate principal amount, containing identical terms and provisions, upon surrender of the Registered Securities to be exchanged at any such office or agency. Whenever any Registered Securities are so surrendered for exchange, the Company shall
execute, and the Trustee shall authenticate and deliver, the Registered Securities which the Holder making the exchange is entitled to receive. Unless otherwise specified with respect to any series of Securities as contemplated by Section 3.01,
Bearer Securities may not be issued in exchange for Registered Securities. 
 If (but only if) permitted by the applicable Board
Resolution and (subject to Section 3.03) set forth in the applicable Officers’ Certificate, or in any indenture supplemental hereto, delivered as contemplated by Section 3.01, at the option of the Holder, Bearer Securities of any
series may be exchanged for Registered Securities of the same series of any authorized denominations and of a like aggregate principal amount and tenor, upon surrender of the Bearer Securities to be exchanged at any such office or agency, with all
unmatured coupons and all matured coupons in default thereto appertaining. If the Holder of a Bearer Security is unable to produce any such unmatured coupon or coupons or matured coupon or coupons in default, any such permitted exchange may be
effected if the Bearer Securities are accompanied by payment in funds acceptable to the Company in an amount equal to the face amount of such missing coupon or coupons, or the surrender of such missing coupon or coupons may be waived by the Company
and the Trustee if there is furnished to them such security or indemnity as they may require to save each of them and any Paying Agent harmless. If thereafter the Holder of such Security shall

  

 27 

Table of Contents

 
surrender to any Paying Agent any such missing coupon in respect of which such a payment shall have been made, such Holder shall be entitled to receive the amount of such payment;
provided, however, that, except as otherwise provided in Section 10.02, interest represented by coupons shall be payable only upon presentation and surrender of those coupons at an office or agency located outside the United
States. Notwithstanding the foregoing, in case a Bearer Security of any series is surrendered at any such office or agency in a permitted exchange for a Registered Security of the same series and like tenor after the close of business at such office
or agency on (i) any Regular Record Date and before the opening of business at such office or agency on the relevant Interest Payment Date or (ii) any Special Record Date and before the opening of business at such office or agency on the
related proposed date for payment of Defaulted Interest, such Bearer Security shall be surrendered without the coupon relating to such Interest Payment Date or proposed date for payment, as the case may be, and interest or Defaulted Interest, as the
case may be, will not be payable on such Interest Payment Date or proposed date for payment, as the case may be, in respect of the Registered Security issued in exchange for such Bearer Security, but will be payable only to the Holder of such coupon
when due in accordance with the provisions of this Indenture. 
 Whenever any Securities are so surrendered for exchange, the
Company shall execute, and the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive. 
 Notwithstanding the foregoing, except as otherwise specified as contemplated by Section 3.01, any permanent global Security shall be exchangeable only as provided in this paragraph. If any beneficial
owner of an interest in a permanent global Security is entitled to exchange such interest for Securities of such series and of like tenor and principal amount of another authorized form and denomination, as specified as contemplated by
Section 3.01 and provided that any applicable notice provided in the permanent global Security shall have been given, then without unnecessary delay but in any event not later than the earliest date on which such interest may be so exchanged,
the Company shall deliver to the Trustee definitive Securities in aggregate principal amount equal to the principal amount of such beneficial owner’s interest in such permanent global Security, executed by the Company. On or after the earliest
date on which such interests may be so exchanged, such permanent global Security shall be surrendered by the Common Depositary or such other depositary as shall be specified in the Company Order with respect thereto to the Trustee, as the
Company’s agent for such purpose, or to the Security Registrar, to be exchanged, in whole or from time to time in part, for definitive Securities of the same series without charge and the Trustee shall authenticate and deliver, in exchange for
each portion of such permanent global Security, an equal aggregate principal amount of definitive Securities of the same series of authorized denominations and of like tenor as the portion of such permanent global Security to be exchanged which,
unless the Securities of the series are not issuable both as Bearer Securities and as Registered Securities, in which case the definitive Securities exchanged for the permanent global Security shall be issuable only in the form in which the
Securities are issuable, as specified as contemplated by Section 3.01, shall be in the form of Bearer Securities or Registered Securities, or any combination thereof, as shall be specified by the beneficial owner thereof; provided,
however, that no such exchanges may occur during a period beginning at the opening of business 15 days before any selection of Securities to be redeemed and ending on the relevant Redemption Date if the Security for which exchange is
requested may be among those selected for redemption; and provided further that no Bearer

  

 28 

Table of Contents

 
Security delivered in exchange for a portion of a permanent global Security shall be mailed or otherwise delivered to any location in the United States. If a Registered Security is issued in
exchange for any portion of a permanent global Security after the close of business at the office or agency where such exchange occurs on (i) any Regular Record Date and before the opening of business at such office or agency on the relevant
Interest Payment Date, or (ii) any Special Record Date and before the opening of business at such office or agency on the related proposed date for payment of Defaulted Interest, interest or Defaulted Interest, as the case may be, will not be
payable on such Interest Payment Date or proposed date for payment, as the case may be, in respect of such Registered Security, but will be payable on such Interest Payment Date or proposed date for payment, as the case may be, only to the Person to
whom interest in respect of such portion of such permanent global Security is payable in accordance with the provisions of this Indenture. 
 All Securities issued upon any registration of transfer or exchange of Securities shall be valid obligations of the Company, evidencing the same debt and entitled to the same benefits under this
Indenture, as the Securities surrendered upon such registration of transfer or exchange. 
 Every Registered Security presented
or surrendered for registration of transfer or for exchange shall (if so required by the Company or the Security Registrar or any transfer agent) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the
Company and the Security Registrar, duly executed by the Holder thereof or his attorney or any transfer agent duly authorized in writing. 
 No service charge shall be made for any registration of transfer or exchange of Securities, but the Company or the Trustee 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 3.04, 9.06, 11.07 or 13.05 not involving any transfer. 
 The Company shall not be required (i) to issue, register the transfer of or exchange any Security if such Security may be among those
selected for redemption during a period beginning at the opening of business 15 days before selection of the Securities to be redeemed under Section 11.03 and ending at the close of business on (A) if such Securities are issuable only as
Registered Securities, the day of the mailing of the relevant notice of redemption and (B) if such Securities are issuable as Bearer Securities, the day of the first publication of the relevant notice of redemption or, if such Securities are
also issuable as Registered Securities and there is no publication, the mailing of the relevant notice of redemption or (ii) to register the transfer of or exchange any Registered Security so selected for redemption in whole or in part, except,
in the case of any Registered Security to be redeemed in part, the portion thereof not to be redeemed, or (iii) to exchange any Bearer Security so selected for redemption except that such a Bearer Security may be exchanged for a Registered
Security of that series and like tenor, provided that such Registered Security shall be simultaneously surrendered for redemption, or (iv) to issue, register the transfer of or exchange any Security which has been surrendered for repayment at
the option of the Holder, except the portion, if any, of such Security not to be so repaid.

 Section 3.06. Mutilated, Destroyed, Lost and Stolen Securities. 
 If any mutilated Security or a Security with a mutilated coupon appertaining to it is surrendered to the Trustee or the Company, together
with, in proper cases, such security or indemnity as may be required by the Company or the Trustee to save each of them or any agent of either of them harmless, the Company shall execute and the Trustee shall authenticate and deliver in exchange
therefor a new Security of the same series and principal amount, containing identical terms and provisions and bearing a number not contemporaneously outstanding, with coupons corresponding to the coupons, if any, appertaining to the surrendered
Security. 
 If there shall be delivered to the Company and to the Trustee (i) evidence to their satisfaction of the
destruction, loss or theft of any Security or coupon and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company or the Trustee that
such Security or coupon has been acquired by a protected purchaser, the Company shall, subject to the following paragraph, execute and upon its request the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen
Security or in exchange for the Security to which a destroyed, lost or stolen coupon appertains (with all appurtenant coupons not destroyed, lost or stolen), a new Security of the same series and principal amount, containing identical terms and
provisions and bearing a number not contemporaneously outstanding, with coupons corresponding to the coupons, if any, appertaining to such destroyed, lost or stolen Security or to the Security to which such destroyed, lost or stolen coupon
appertains. 
 Notwithstanding the provisions of the previous two paragraphs, in case any such mutilated, destroyed, lost or
stolen Security or coupon has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Security, with coupons corresponding to the coupons, if any, appertaining to such mutilated, destroyed, lost or
stolen Security or to the Security to which such mutilated, destroyed, lost or stolen coupon appertains, pay such Security or coupon, as the case may be; provided, however, that payment of principal of (and premium, if any) and
interest, if any, on Bearer Securities shall, except as otherwise provided in Section 10.02, be payable only at an office or agency located outside the United States and, unless otherwise specified as contemplated by Section 3.01, any
interest on Bearer Securities shall be payable only upon presentation and surrender of the coupons appertaining thereto. 
 Upon
the issuance of any new Security under this Section, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and
expenses of the Trustee) connected therewith. 
 Every new Security of any series with its coupons, if any, issued pursuant to
this Section in lieu of any destroyed, lost or stolen Security, or in exchange for a Security to which a destroyed, lost or stolen coupon appertains, shall constitute an original additional contractual obligation of the Company, whether or not the
destroyed, lost or stolen Security and its coupons, if any, or the destroyed, lost or stolen coupon shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all
other Securities of that series and their coupons, if any, duly issued hereunder.

 The provisions of this Section are exclusive and shall preclude (to the extent lawful) all
other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities or coupons. 
 Section 3.07. Payment of Interest; Interest Rights Preserved; Optional Interest Reset. 
 (a) Except as
otherwise specified with respect to a series of Securities in accordance with the provisions of Section 3.01, interest, if any, on any Registered Security that is payable, and is punctually paid or duly provided for, on any Interest Payment
Date shall be paid to the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest at the office or agency of the Company maintained for such
purpose pursuant to Section 10.02; provided, however, that each installment of interest, if any, on any Registered Security may at the Company’s option be paid by (i) mailing a check for such interest, payable to or upon
the written order of the Person entitled thereto pursuant to Section 3.09, to the address of such Person as it appears on the Security Register or (ii) transfer to an account maintained by the payee located in the United States.

 Unless otherwise provided as contemplated by Section 3.01 with respect to the Securities of any series, payment of
interest, if any, may be made, in the case of a Bearer Security, by transfer to an account maintained by the payee with a bank located outside the United States. 
 Unless otherwise provided as contemplated by Section 3.01, every permanent global Security will provide that interest, if any, payable on any Interest Payment Date will be paid to each of Euroclear
and Clearstream with respect to that portion of such permanent global Security held for its account by the Common Depositary, for the purpose of permitting each of Euroclear and Clearstream to credit the interest, if any, received by it in respect
of such permanent global Security to the accounts of the beneficial owners thereof. 
 In case a Bearer Security of any series
is surrendered in exchange for a Registered Security of such series after the close of business (at an office or agency in a Place of Payment for such series) on any Regular Record Date and before the opening of business (at such office or agency)
on the next succeeding Interest Payment Date, such Bearer Security shall be surrendered without the coupon relating to such Interest Payment Date and interest will not be payable on such Interest Payment Date in respect of the Registered Security
issued in exchange for such Bearer Security, but will be payable only to the Holder of such coupon when due in accordance with the provisions of this Indenture. 
 Except as otherwise specified with respect to a series of Securities in accordance with the provisions of Section 3.01, any interest on any Registered Security of any series that is payable, but is
not punctually paid or duly provided for, on any Interest Payment Date (herein called “Defaulted Interest”) shall forthwith cease to be payable to the registered Holder thereof on the relevant Regular Record Date by virtue of having
been such Holder, and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in clause (1) or (2) below:

Table of Contents

 (1) The Company may elect to make payment of any Defaulted Interest to the
Persons in whose names the Registered Securities of such series (or their respective Predecessor Securities) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the
following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Registered Security of such series and the date of the proposed payment (which shall not be less than 20 days after
such notice is received by the Trustee), and at the same time the Company shall deposit with the Trustee an amount of money in the Currency in which the Securities of such series are payable (except as otherwise specified pursuant to
Section 3.01 for the Securities of such series and except, if applicable, as provided in Sections 3.12(b), 3.12(d) and 3.12(e)) equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements
satisfactory to the Trustee for such deposit on or prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this clause provided. Thereupon the
Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of
the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special
Record Date therefor to be mailed, first-class postage prepaid, to each Holder of Registered Securities of such series at his address as it appears in the Security Register not less than 10 days prior to such Special Record Date. Notice of the
proposed payment of such Defaulted Interest and the Special Record Date therefor having been mailed as aforesaid, such Defaulted Interest shall be paid to the Persons in whose names the Registered Securities of such series (or their respective
Predecessor Securities) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following clause (2). In case a Bearer Security of any series is surrendered at the office or agency in a
Place of Payment for such series in exchange for a Registered Security of such series after the close of business at such office or agency on any Special Record Date and before the opening of business at such office or agency on the related proposed
date for payment of Defaulted Interest, such Bearer Security shall be surrendered without the coupon relating to such proposed date of payment and Defaulted Interest will not be payable on such proposed date of payment in respect of the Registered
Security issued in exchange for such Bearer Security, but will be payable only to the Holder of such coupon when due in accordance with the provisions of this Indenture. 
 (2) The Company may make payment of any Defaulted Interest on the Registered Securities of any series in any other lawful
manner not inconsistent with the requirements of any securities exchange on which such Securities may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment
pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee. 
 (b) The provisions of this
Section 3.07(b) may be made applicable to any series of Securities pursuant to Section 3.01 (with such modifications, additions or substitutions as may be

  

 32 

Table of Contents

 
specified pursuant to such Section 3.01). The interest rate (or the spread or spread multiplier used to calculate such interest rate, if applicable) on any Security of such series may be
reset by the Company on the date or dates specified on the face of such Security (each an “Optional Reset Date”). The Company may exercise such option with respect to such Security by notifying the Trustee of such exercise at least
45 but not more than 60 days prior to an Optional Reset Date for such Security. Not later than 40 days prior to each Optional Reset Date, the Trustee shall transmit, in the manner provided for in Section 1.06, to the Holder of any such Security
a notice (the “Reset Notice”) indicating whether the Company has elected to reset the interest rate (or the spread or spread multiplier used to calculate such interest rate, if applicable), and if so (i) such new interest rate
(or such new spread or spread multiplier, if applicable) and (ii) the provisions, if any, for redemption during the period from such Optional Reset Date to the next Optional Reset Date or if there is no such next Optional Reset Date, to the
Stated Maturity of such Security (each such period a “Subsequent Interest Period”), including the date or dates on which or the period or periods during which and the price or prices at which such redemption may occur during the
Subsequent Interest Period. 
 Notwithstanding the foregoing, not later than 20 days prior to the Optional Reset Date, the
Company may, at its option, revoke the interest rate (or the spread or spread multiplier used to calculate such interest rate, if applicable) provided for in the Reset Notice and establish a higher interest rate (or a spread or spread multiplier
providing for a higher interest rate, if applicable) for the Subsequent Interest Period by causing the Trustee to transmit, in the manner provided for in Section 1.06, notice of such higher interest rate (or such higher spread or spread
multiplier providing for a higher interest rate, if applicable) to the Holder of such Security. Such notice shall be irrevocable. All Securities with respect to which the interest rate (or the spread or spread multiplier used to calculate such
interest rate, if applicable) is reset on an Optional Reset Date, and with respect to which the Holders of such Securities have not tendered such Securities for repayment (or have validly revoked any such tender) pursuant to the next succeeding
paragraph, will bear such higher interest rate (or such higher spread or spread multiplier providing for a higher interest rate, if applicable). 
 The Holder of any such Security will have the option to elect repayment by the Company of the principal of such Security on each Optional Reset Date at a price equal to the principal amount thereof plus
interest accrued to such Optional Reset Date. In order to obtain repayment on an Optional Reset Date, the Holder must follow the procedures set forth in Article Thirteen for repayment at the option of Holders except that the period for delivery or
notification to the Trustee shall be at least 25 but not more than 35 days prior to such Optional Reset Date and except that, if the Holder has tendered any Security for repayment pursuant to the Reset Notice, the Holder may, by written notice to
the Trustee, revoke such tender or repayment until the close of business on the tenth day before such Optional Reset Date. 
 Subject to the foregoing provisions of this Section and Section 3.05, 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 3.08. Optional Extension of Maturity. 
 The provisions of this Section 3.08 may be made applicable to any series of Securities pursuant to Section 3.01 (with such
modifications, additions or substitutions as may be specified pursuant to such Section 3.01). The Stated Maturity of any Security of such series may be extended at the option of the Company for the period or periods specified on the face of
such Security (each an “Extension Period”) up to but not beyond the date (the “Final Maturity”) set forth on the face of such Security. The Company may exercise such option with respect to any Security by notifying
the Trustee of such exercise at least 45 but not more than 60 days prior to the Stated Maturity of such Security in effect prior to the exercise of such option (the “Original Stated Maturity”). If the Company exercises such option,
the Trustee shall transmit, in the manner provided for in Section 1.06, to the Holder of such Security not later than 40 days prior to the Original Stated Maturity a notice (the “Extension Notice”), prepared by the Company,
indicating (i) the election of the Company to extend the Stated Maturity, (ii) the new Stated Maturity, (iii) the interest rate (or spread, spread multiplier or other formula to calculate such interest rate, if applicable), if any,
applicable to the Extension Period and (iv) the provisions, if any, for redemption during such Extension Period. Upon the Trustee’s transmittal of the Extension Notice, the Stated Maturity of such Security shall be extended automatically
and, except as modified by the Extension Notice and as described in the next paragraph, such Security will have the same terms as prior to the transmittal of such Extension Notice. 
 Notwithstanding the foregoing, not later than 20 days before the Original Stated Maturity of such Security, the Company may, at its option,
revoke the interest rate (or spread, spread multiplier or other formula to calculate such interest rate, if applicable) provided for in the Extension Notice and establish a higher interest rate (or spread, spread multiplier or other formula to
calculate such higher interest rate, if applicable) for the Extension Period by causing the Trustee to transmit, in the manner provided for in Section 1.06, notice of such higher interest rate (or spread, spread multiplier or other formula to
calculate such interest rate, if applicable) to the Holder of such Security. Such notice shall be irrevocable. All Securities with respect to which the Stated Maturity is extended will bear such higher interest rate. 
 If the Company extends the Stated Maturity of any Security, the Holder will have the option to elect repayment of such Security by the
Company on the Original Stated Maturity at a price equal to the principal amount thereof, plus interest accrued to such date. In order to obtain repayment on the Original Stated Maturity once the Company has extended the Stated Maturity thereof, the
Holder must follow the procedures set forth in Article Thirteen for repayment at the option of Holders, except that the period for delivery or notification to the Trustee shall be at least 25 but not more than 35 days prior to the Original Stated
Maturity and except that, if the Holder has tendered any Security for repayment pursuant to an Extension Notice, the Holder may by written notice to the Trustee revoke such tender for repayment until the close of business on the tenth day before the
Original Stated Maturity. 
 Section 3.09. Persons Deemed Owners. 
 Prior to due presentment of a Registered Security for registration of transfer, the Company, the Trustee and any agent of the Company or the
Trustee may treat the Person in whose name such Registered Security is registered as the owner of such Registered Security for

  

 34 

Table of Contents

 
the purpose of receiving payment of principal of (and premium, if any) and (subject to Sections 3.05 and 3.07) interest, if any, on such Registered Security and for all other purposes whatsoever,
whether or not such Registered Security be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary. 
 Title to any Bearer Security and any coupons appertaining thereto shall pass by delivery. The Company, the Trustee and any agent of the
Company or the Trustee may treat the bearer of any Bearer Security and the bearer of any coupon as the absolute owner of such Security or coupon for the purpose of receiving payment thereof or on account thereof and for all other purposes
whatsoever, whether or not such Security or coupon be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary. 
 None of the Company, the Trustee, any Paying Agent or the Security Registrar will have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership interests of a Security in global form or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests. 
 Notwithstanding the foregoing, with respect to any global temporary or permanent Security, nothing herein shall prevent the Company, the
Trustee, or any agent of the Company or the Trustee, from giving effect to any written certification, proxy or other authorization furnished by any depositary, as a Holder, with respect to such global Security or impair, as between such depositary
and owners of beneficial interests in such global Security, the operation of customary practices governing the exercise of the rights of such depositary (or its nominee) as Holder of such global Security. 
 Section 3.10. Cancellation. 
 All Securities and coupons surrendered for payment, redemption, repayment at the option of the Holder, registration of transfer or exchange or for credit against any sinking fund payment shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee, and any such Securities and coupons and Securities and coupons surrendered directly to the Trustee for any such purpose shall be promptly cancelled by the Trustee. 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 cancelled by the Trustee. If the Company shall so acquire any of
the Securities, however, such acquisition shall not operate as a redemption or satisfaction of the indebtedness represented by such Securities unless and until the same are surrendered to the Trustee for cancellation. No Securities shall be
authenticated in lieu of, or in exchange for, any Securities cancelled as provided in this Section, except as expressly permitted by this Indenture. Cancelled Securities and coupons held by the Trustee shall be destroyed by the Trustee in accordance
with its customary procedures, unless by a Company Order the Company directs the Trustee to deliver a certificate of such destruction to the Company or to return them to the Company.

 Section 3.11. Computation of Interest. 
 Except as otherwise specified as contemplated by Section 3.01 with respect to Securities of any series, interest, if any, on the
Securities of each series shall be computed on the basis of a 360-day year consisting of twelve 30-day months. 
 Section
3.12. Currency and Manner of Payments in Respect of Securities. 
 (a) Unless otherwise specified with respect to any
Securities pursuant to Section 3.01, with respect to Registered Securities of any series not permitting the election provided for in paragraph (b) below or the Holders of which have not made the election provided for in paragraph
(b) below, and with respect to Bearer Securities of any series, except as provided in paragraph (d) below, payment of the principal of (and premium, if any) and interest, if any, on any Registered or Bearer Security of such series will be
made in the Currency in which such Registered Security or Bearer Security, as the case may be, is payable. The provisions of this Section 3.12 may be modified or superseded with respect to any Securities pursuant to Section 3.01.

 (b) Section 3.01 may provide that Holders of any series of Registered Securities shall have the option, subject to
paragraphs (d) and (e) below, to receive payments of principal of (or premium, if any) or interest, if any, on such Registered Securities in any of the Currencies that may be designated for such election by delivering to the Trustee for
such series of Registered Securities a written election with signature guarantees and in the applicable form established pursuant to Section 3.01, not later than the close of business on the Election Date immediately preceding the applicable
payment date. If a Holder so elects to receive such payments in any such Currency, such election will remain in effect for such Holder or any transferee of such Holder until changed by such Holder or such transferee by written notice to the Trustee
for such series of Registered Securities (but any such change must be made not later than the close of business on the Election Date immediately preceding the next payment date to be effective for the payment to be made on such payment date and no
such change of election may be made with respect to payments to be made on any Registered Security of such series with respect to which an Event of Default has occurred or with respect to which the Company has deposited funds pursuant to Article
Four or Fourteen or with respect to which a notice of redemption has been given by the Company or a notice of option to elect repayment has been sent by such Holder or such transferee). Any Holder of any such Registered Security who shall not have
delivered any such election to the Trustee of such series of Registered Securities not later than the close of business on the applicable Election Date will be paid the amount due on the applicable payment date in the relevant Currency as provided
in Section 3.12(a). The Trustee for each such series of Registered Securities shall notify the Exchange Rate Agent as soon as practicable after the Election Date of the aggregate principal amount of Registered Securities for which Holders have
made such written election. 
 (c) Unless otherwise specified pursuant to Section 3.01, if the election referred to in
paragraph (b) above has been provided for pursuant to Section 3.01, then, unless otherwise specified pursuant to Section 3.01, not later than the fourth Business Day after the Election Date for each payment date for Registered
Securities of any series, the Exchange Rate Agent will deliver to the Company a written notice specifying the Currency in which Registered Securities

  

 36 

Table of Contents

 
of such series are payable, the respective aggregate amounts of principal of (and premium, if any) and interest, if any, on the Registered Securities to be paid on such payment date, specifying
the amounts in such Currency so payable in respect of the Registered Securities as to which the Holders of Registered Securities denominated in any Currency shall have elected to be paid in another Currency as provided in paragraph (b) above.
If the election referred to in paragraph (b) above has been provided for pursuant to Section 3.01 and if at least one Holder has made such election, then, unless otherwise specified pursuant to Section 3.01, on the second Business Day
preceding such payment date the Company will deliver to the Trustee for such series of Registered Securities an Exchange Rate Officer’s Certificate in respect of the Dollar or Foreign Currency or Currencies payments to be made on such payment
date. Unless otherwise specified pursuant to Section 3.01, the Dollar or Foreign Currency or Currencies amount receivable by Holders of Registered Securities who have elected payment in a Currency as provided in paragraph (b) above shall
be determined by the Company on the basis of the applicable Market Exchange Rate in effect on the second Business Day (the “Valuation Date”) immediately preceding each payment date, and such determination shall be conclusive and
binding for all purposes, absent manifest error. 
 (d) If a Conversion Event occurs with respect to a Foreign Currency in which
any of the Securities are denominated or payable other than pursuant to an election provided for pursuant to paragraph (b) above, then with respect to each date for the payment of principal of (and premium, if any) and interest, if any on the
applicable Securities denominated or payable in such Foreign Currency occurring after the last date on which such Foreign Currency was used (the “Conversion Date”), the Dollar shall be the currency of payment for use on each such
payment date. Unless otherwise specified pursuant to Section 3.01, the Dollar amount to be paid by the Company to the Trustee of each such series of Securities and by such Trustee or any Paying Agent to the Holders of such Securities with
respect to such payment date shall be, in the case of a Foreign Currency other than a currency unit, the Dollar Equivalent of the Foreign Currency or, in the case of a currency unit, the Dollar Equivalent of the Currency Unit, in each case as
determined by the Exchange Rate Agent in the manner provided in paragraph (f) or (g) below. 
 (e) Unless otherwise
specified pursuant to Section 3.01, if the Holder of a Registered Security denominated in any Currency shall have elected to be paid in another Currency as provided in paragraph (b) above, and a Conversion Event occurs with respect to such
elected Currency, such Holder shall receive payment in the Currency in which payment would have been made in the absence of such election; and if a Conversion Event occurs with respect to the Currency in which payment would have been made in the
absence of such election, such Holder shall receive payment in Dollars as provided in paragraph (d) of this Section 3.12. 
 (f) The “Dollar Equivalent of the Foreign Currency” shall be determined by the Exchange Rate Agent and shall be obtained for each subsequent payment date by converting the specified Foreign Currency into Dollars at the Market
Exchange Rate on the Conversion Date. 
 (g) The “Dollar Equivalent of the Currency Unit” shall be determined by the
Exchange Rate Agent and subject to the provisions of paragraph (h) below shall be the sum of each amount obtained by converting the Specified Amount of each Component Currency into

  

 37 

Table of Contents

 
Dollars at the Market Exchange Rate for such Component Currency on the Valuation Date with respect to each payment. 
 (h) For purposes of this Section 3.12, the following terms shall have the following meanings: 
 A “Component Currency” shall mean any currency which, on the Conversion Date, was a component currency of the relevant currency unit. 
 A “Specified Amount” of a Component Currency shall mean the number of units of such Component Currency or
fractions thereof which were represented in the relevant currency unit on the Conversion Date. If, after the Conversion Date, the official unit of any Component Currency is altered by way of combination or subdivision, the Specified Amount of such
Component Currency shall be divided or multiplied in the same proportion. If after the Conversion Date two or more Component Currencies are consolidated into a single currency, the respective Specified Amounts of such Component Currencies shall be
replaced by an amount in such single currency equal to the sum of the respective Specified Amounts of such consolidated Component Currencies expressed in such single currency, and such amount shall thereafter be a Specified Amount and such single
currency shall thereafter be a Component Currency. If after the Conversion Date any Component Currency shall be divided into two or more currencies, the Specified Amount of such Component Currency shall be replaced by amounts of such two or more
currencies, having an aggregate Dollar Equivalent value at the Market Exchange Rate on the date of such replacement equal to the Dollar Equivalent of the Specified Amount of such former Component Currency at the Market Exchange Rate immediately
before such division, and such amounts shall thereafter be Specified Amounts and such currencies shall thereafter be Component Currencies. If, after the Conversion Date of the relevant currency unit, a Conversion Event (other than any event referred
to above in this definition of “Specified Amount”) occurs with respect to any Component Currency of such currency unit and is continuing on the applicable Valuation Date, the Specified Amount of such Component Currency shall, for purposes
of calculating the Dollar Equivalent of the Currency Unit, be converted into Dollars at the Market Exchange Rate in effect on the Conversion Date of such Component Currency. 
 An “Election Date” shall mean the Regular Record Date for the applicable series of Registered Securities or
at least 16 days prior to Maturity, as the case may be, or such other prior date for any series of Registered Securities as specified pursuant to clause 13 of Section 3.01 by which the written election referred to in Section 3.12(b) may be
made. 
 All decisions and determinations of the Exchange Rate Agent regarding the Dollar Equivalent of the Foreign Currency,
the Dollar Equivalent of the Currency Unit, the Market Exchange Rate and changes in the Specified Amounts as specified above shall be in its sole discretion and shall, in the absence of manifest error, be conclusive for all purposes and irrevocably
binding upon the Company, the Trustee for the appropriate series of Securities and all Holders of such Securities denominated or payable in the relevant Currency. The Exchange Rate Agent shall promptly give written notice to the Company and the
Trustee for the appropriate series of Securities of any such decision or determination. 
  

 38 

Table of Contents

 In the event that the Company determines in good faith that a Conversion Event has occurred
with respect to a Foreign Currency, the Company will immediately give written notice thereof to the Trustee of the appropriate series of Securities and to the Exchange Rate Agent (and such Trustee will promptly thereafter give notice in the manner
provided in Section 1.06 to the affected Holders) specifying the Conversion Date. In the event the Company so determines that a Conversion Event has occurred with respect to any currency unit in which Securities are denominated or payable, the
Company will immediately give written notice thereof to the Trustee of the appropriate series of Securities and to the Exchange Rate Agent (and such Trustee will promptly thereafter give notice in the manner provided in Section 1.06 to the
affected Holders) specifying the Conversion Date and the Specified Amount of each Component Currency on the Conversion Date. In the event the Company determines in good faith that any subsequent change in any Component Currency as set forth in the
definition of Specified Amount above has occurred, the Company will similarly give written notice to the Trustee of the appropriate series of Securities and to the Exchange Rate Agent. 
 The Trustee of the appropriate series of Securities shall be fully justified and protected in relying and acting upon information received
by it from the Company and the Exchange Rate Agent and shall not otherwise have any duty or obligation to determine the accuracy or validity of such information independent of the Company or the Exchange Rate Agent. 
 Section 3.13. Appointment and Resignation of Successor Exchange Rate Agent. 
 (a) Unless otherwise specified pursuant to Section 3.01, if and so long as the Securities of any series (i) are denominated in a
Foreign Currency or (ii) may be payable in a Foreign Currency, or so long as it is required under any other provision of this Indenture, then the Company will maintain with respect to each such series of Securities, or as so required, at least
one Exchange Rate Agent. The Company will cause the Exchange Rate Agent to make the necessary foreign exchange determinations at the time and in the manner specified pursuant to Section 3.01 for the purpose of determining the applicable rate of
exchange and, if applicable, for the purpose of converting the issued Foreign Currency into the applicable payment Currency for the payment of principal (and premium, if any) and interest, if any, pursuant to Section 3.12. 
 (b) No resignation of the Exchange Rate Agent and no appointment of a successor Exchange Rate Agent pursuant to this Section shall become
effective until the acceptance of appointment by the successor Exchange Rate Agent as evidenced by a written instrument delivered to the Company and the Trustee of the appropriate series of Securities accepting such appointment executed by the
successor Exchange Rate Agent. 
 (c) If the Exchange Rate Agent shall resign, be removed or become incapable of acting, or if a
vacancy shall occur in the office of the Exchange Rate Agent 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 Exchange Rate Agent or Exchange
Rate Agents with respect to the Securities of that or those series (it being understood that any such successor Exchange Rate Agent may be appointed with respect to the Securities of one or more or all of such series and that, unless otherwise
specified pursuant to Section 3.01, at any time there shall only be one Exchange Rate Agent with respect to the Securities of any particular series that are

originally issued by the Company on the same date and that are initially denominated and/or payable in the same Currency). 
 Section 3.14. CUSIP Numbers. 
 The Company in issuing the Securities may use “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall indicate the respective “CUSIP” numbers of the Securities 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 redemption
and that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company shall advise the Trustee as promptly as
practicable in writing of any change in the CUSIP numbers.

 Section 5.02. Acceleration of Maturity; Rescission and Annulment. 
 If an Event of Default with respect to Securities of any series at the time Outstanding occurs and is continuing, then and in every such
case the Trustee or the Holders of not less than 25% in principal amount of the Outstanding Securities of that series may declare the principal (or, if any Securities are Original Issue Discount Securities or Indexed Securities, such portion of the
principal as may be specified in the terms thereof) of all the Securities of that series to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by the Holders), and upon any such declaration such
principal or specified portion thereof shall become immediately due and payable. 
 At any time after such a declaration of
acceleration with respect to Securities of any series has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter provided in this Article, the Holders of a majority in principal amount
of the Outstanding Securities of that series, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if: 
 (1) the Company has paid or deposited with the Trustee a sum sufficient to pay in the Currency in which the Securities of such series are payable (except as otherwise specified pursuant to
Section 3.01 for the Securities of such series and except, if applicable, as provided in Sections 3.12(b), 3.12(d) and 3.12(e)): 
 (A) all overdue installments of interest, if any, on all Outstanding Securities of that series and any related coupons,

 (2) all Events of Default with respect to Securities of that series, other than the nonpayment of the principal of (or premium, if any) or interest on Securities of that series which have become due
solely by such declaration of acceleration, have been cured or waived as provided in Section 5.13. 
 No such rescission
shall affect any subsequent default or impair any right consequent thereon. 
 Section 5.03. Collection of Indebtedness and
Suits for Enforcement by Trustee. 
 The Company covenants that if: 
 (1) default is made in the payment of any installment of interest on any Security of any series and any related coupon when such interest
becomes due and payable and such default continues for a period of 30 days, or 
 (2) default is made in the payment of the
principal of (or premium, if any) any Security of any series and continues for a period of five days after Maturity, 
 then the Company will,
upon demand of the Trustee, pay to the Trustee, for the benefit of the Holders of Securities of such series and coupons, the whole amount then due and payable on such Securities and coupons for principal (and premium, if any) and interest, if any,
with interest upon any overdue principal (and premium, if any) and, to the extent that payment of such interest shall be legally enforceable, upon any overdue installments of interest, if any, at the rate or rates borne by or provided for in such
Securities, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

 If the Company fails to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an
express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, and may prosecute such proceeding to judgment or final decree, and may enforce the same against the Company or any other obligor upon Securities of
such series and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon such Securities of such series, wherever situated. 
 If an Event of Default with respect to Securities of any series occurs and is continuing, the Trustee may in its discretion proceed to
protect and enforce its rights and the rights of the Holders of Securities of such series and any related coupons by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights,

declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the payment of any overdue principal, premium or interest) shall be entitled and empowered, by intervention in such proceeding or
otherwise:

 THIRD: To the payment of the remainder, if any, to the Company or any other Person or Persons entitled thereto. 

Section 5.07. Limitation on Suits. 
 No Holder of any Security of any series or any related coupon shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver
or trustee, or for any other remedy hereunder, unless:

exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise.
The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. 
 Section 5.11. Delay or Omission Not Waiver. 
 No delay or omission of the Trustee or of any Holder of any Security or coupon to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a
waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by
the Holders of Securities or coupons, as the case may be.

of the Holder of each Outstanding Security of such series affected. 
 Upon any such waiver, such default shall cease to exist,
and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture, but no such waiver shall extend to any subsequent or other default or Event of Default or impair any right consequent thereon.

 Section 5.14. Waiver of Stay or Extension Laws. 
 The Company covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner
whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may

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). 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, become the successor Trustee with respect to the Securities of such series and to that
extent supersede the successor Trustee appointed by the Company. If no successor Trustee with respect to the Securities of any series shall have been so appointed by the Company or the Holders of Securities and accepted appointment in the manner
hereinafter provided, any Holder of a Security who has been a bona fide Holder of a Security of such series for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the
appointment of a successor Trustee with respect to Securities of such series.

 Section 6.10. Acceptance of Appointment by Successor. 
 (a) In case of the appointment hereunder of a successor Trustee with respect to all Securities, every such successor Trustee shall execute,
acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act,
deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on request of the Company or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an
instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee, and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder,
subject nevertheless to its claim, if any, provided for in Section 6.06. 
 (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. Whenever there is a successor Trustee with respect to one or more (but less than all) series of securities issued pursuant to this Indenture, the
terms “Indenture” and “Securities” shall have the meanings specified in the provisos to the respective definition of those terms in Section 1.01 which contemplate such situation.

hereunder, provided such corporation shall be otherwise qualified and eligible under this Article Six, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Securities or coupons shall
have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities or coupons so authenticated with
the same effect as if such successor Trustee had itself authenticated such Securities or coupons. In case any Securities or coupons shall not have been authenticated by such predecessor Trustee, any such successor Trustee may authenticate and
deliver such Securities or coupons, in either its own name or that of its predecessor Trustee, with the full force and effect which this Indenture provides for the certificate of authentication of the Trustee; provided, however, that
the right to adopt the certificate of authentication of any predecessor Trustee or to authenticate Securities in the name of any predecessor Trustee shall apply only to its successor or successors by merger, conversion or consolidation. 

Section 6.12. Appointment of Authenticating Agent. 
 At any time when any of the Securities remain Outstanding, the Trustee may appoint an Authenticating Agent or Agents acceptable to the Company (which may be an Affiliate or Affiliates of the Company) 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 or upon exchange, registration of transfer or partial redemption thereof, and
Securities so authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Any such appointment shall be evidenced by an instrument in writing
signed by a Responsible Officer of the Trustee, a copy of which instrument shall be promptly furnished to the Company. Wherever reference is made in this Indenture to the authentication and delivery of Securities by the Trustee or the Trustee’s
certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating
Agent. Each Authenticating Agent shall be acceptable to the Company and, except as may otherwise be provided pursuant to Section 3.01, shall at all times be a bank or trust company or corporation organized and doing business and in good
standing under the laws of the United States of America or of any State or the District of Columbia, authorized under such laws to act as

Authenticating Agent, having a combined capital and surplus of not less than $150,000 and subject to supervision or examination by Federal or State authorities. If such Authenticating Agent
publishes reports of condition at least annually, pursuant to law or the requirements of the aforesaid supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Authenticating Agent shall be
deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. In case at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, such
Authenticating Agent shall resign immediately in the manner and with the effect specified in this Section. 
 Any corporation
into which an Authenticating Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation
succeeding to the corporate agency or corporate trust business of an Authenticating Agent, shall continue to be an Authenticating Agent, provided such corporation shall be otherwise eligible under this Section, without the execution or filing
of any paper or further act on the part of the Trustee or the Authenticating Agent. 
 An Authenticating Agent for any series of
Securities may at any time resign by giving written notice of resignation to the Trustee for such series and to the Company. The Trustee for any series of Securities may at any time terminate the agency of an Authenticating Agent by giving written
notice of termination to such Authenticating Agent and to the Company. Upon receiving such a notice of resignation or upon such a termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee for such series may appoint a successor Authenticating Agent which shall be acceptable to the Company and shall promptly give written notice of such appointment to all Holders of Securities of the series with
respect to which such Authenticating Agent will serve in the manner set forth in Section 1.06. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers and duties of its
predecessor hereunder, with like effect as if originally named as an Authenticating Agent herein. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section. 
 The Company agrees to pay to each Authenticating Agent from time to time reasonable compensation including reimbursement of its reasonable
expenses for its services under this Section. 
 If an appointment with respect to one or more series is made pursuant to this
Section, the Securities of such series may have endorsed thereon, in addition to or in lieu of the Trustee’s certificate of authentication, an alternate certificate of authentication substantially in the following form: 
 This is one of the Securities of the series designated therein referred to in the Indenture referenced herein.

in respect of any series of Securities or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee, except that Bearer
Securities of that series and the related coupons may be presented and surrendered for payment (including payment of any Additional Amounts payable on Bearer Securities of that series pursuant to Section 10.04) at the offices specified in the
Security, and the Company hereby appoints the same as its agent to receive such respective presentations, surrenders, notices and demands, and the Company hereby appoints the Trustee its agent to receive all such presentations, surrenders, notices
and demands. 
 Unless otherwise specified with respect to any Securities pursuant to Section 3.01, no payment of
principal, premium or interest on Bearer Securities shall be made at any office or agency of the Company in the United States or by check mailed to any address in the United States or by transfer to any account maintained with a financial
institution located in the United States; provided, however, that, if the Securities of a series are denominated and payable in Dollars, payment of principal of (and premium, if any) and interest, if any, on any Bearer Security
(including payment of any Additional Amounts payable on Bearer Securities of that series pursuant to Section 10.04) shall be made at the office of the Company’s Paying Agent in The City of New York, if (but only if) payment in Dollars of
the full amount of such principal, premium, if any, interest or Additional Amounts, as the case may be, at all offices or agencies outside the United States maintained for such purpose by the Company in accordance with this Indenture, is illegal or
effectively precluded by exchange controls or other similar restrictions. 
 The Company may also from time to time designate
one or more other offices or agencies where the Securities of one or more series may be presented or surrendered for any or all of such purposes, and may from time to time rescind such designations; provided, however, that no such
designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in accordance with the requirements set forth above for Securities of any series for such purposes. The Company will give prompt
written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. Unless otherwise specified with respect to any Securities pursuant to Section 3.01 with respect to a
series of Securities, the Company hereby designates as a Place of Payment for each series of Securities the office or agency of the Company in The City of New York, and initially appoints the Trustee at its Corporate Trust Office as Paying Agent in
The City of New York and as its agent to receive all such presentations, surrenders, notices and demands. 
 Unless otherwise
specified with respect to any Securities pursuant to Section 3.01, if and so long as the Securities of any series (i) are denominated in a currency other than Dollars or (ii) may be payable in a currency other than Dollars, or so long
as it is required under any other provision of the Indenture, then the Company will maintain with respect to each such series of Securities, or as so required, at least one Exchange Rate Agent.

 Section 10.03. Money for Securities Payments to Be Held in Trust. 
 If the Company shall at any time act as its own Paying Agent with respect to any series of any Securities and any related coupons, it will,
on or before each due date of the principal of (or premium, if any) or interest, if any, on any of the Securities of that series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum in the Currency in which the
Securities of such series are payable (except as otherwise specified pursuant to Section 3.01 for the Securities of such series and except, if applicable, as provided in Sections 3.12(b), 3.12(d) and 3.12(e)) sufficient to pay the principal
(and premium, if any) and interest, if any, on Securities of such series so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided, and will promptly notify the Trustee of its action or failure so to
act. 
 Whenever the Company shall have one or more Paying Agents for any series of Securities and any related coupons, it will,
on or before each due date of the principal of (or premium, if any) or interest, if any, on any Securities of that series, deposit with a Paying Agent a sum (in the Currency or Currencies described in the preceding paragraph) sufficient to pay the
principal (or premium, if any) or interest, if any, so becoming due, such sum of money 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 may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay, to the Trustee all sums of money held in trust by the Company or such Paying Agent, such sums to be held by the Trustee
upon the same trusts as those upon which such sums were held by the Company or such Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such sums.

 Except as otherwise provided in the Securities of any series, any money deposited with the Trustee or any Paying Agent, or
then held by the Company, in trust for the payment of the principal of (or premium, if any) or interest, if any, on any Security of any series, or any coupon appertaining thereto, and remaining unclaimed for two years after such principal, premium
or interest has become due and payable shall be paid to the Company upon Company Request, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Security or any coupon appertaining thereto shall thereafter, as
an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such money held in trust, and all liability of the Company as trustee thereof, shall thereupon cease;
provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in an Authorized Newspaper, notice that such money remains
unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication, any unclaimed balance of such money then remaining will be repaid to the Company.

 Section 10.04. Additional Amounts. 
 If the Securities of a series provide for the payment of Additional Amounts, the Company will pay to the Holder of any Security of such
series or any coupon appertaining thereto such Additional Amounts as may be specified as contemplated by Section 3.01. Whenever in this Indenture there is mentioned, in any context, the payment of the principal of (or premium, if any) or
interest, if any, on any Security of any series or payment of any related coupon or the net proceeds received on the sale or exchange of any Security of any series, such mention shall be deemed to include mention of the payment of Additional Amounts
provided for by the terms of such series established pursuant to Section 3.01 to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof pursuant to such terms and express mention of the payment of
Additional Amounts (if applicable) in any provisions hereof shall not be construed as excluding Additional Amounts in those provisions hereof where such express mention is not made. 
 Except as otherwise specified as contemplated by Section 3.01, if the Securities of a series provide for the payment of Additional
Amounts, at least 10 days prior to the first Interest Payment Date with respect to that series of Securities (or if the Securities of that series will not bear interest prior to Maturity, the first day on which a payment of principal premium is
made), and at least 10 days prior to each date of payment of principal, premium or interest if there has been any change with respect to the matters set forth in the below-mentioned Officers’ Certificate, the Company will furnish the Trustee
and the Company’s principal Paying Agent or Paying Agents, if other than the Trustee, with an Officers’ Certificate instructing the Trustee and such Paying Agent or Paying Agents whether such payment of principal, premium or interest on
the Securities of that series shall be made to Holders of Securities of that series or any related coupons who are not United States persons without withholding for or on account of any tax, assessment or other governmental charge described in the
Securities of that series. If any such withholding shall be required, then such Officers’ Certificate shall specify by country the amount, if any, required to be withheld on such payments to such Holders of Securities of that series or related
coupons and the Company will pay to the Trustee or such Paying Agent the Additional Amounts required by the terms of such Securities. In the event that the Trustee or any Paying Agent, as the case may be, shall not so receive the above-mentioned
certificate, then the Trustee or such Paying Agent shall be entitled (i) to assume that no such withholding or deduction is required with respect to any payment of principal or interest with respect to any Securities of a series or related
coupons until it shall have received a certificate advising otherwise and (ii) to make all payments of principal and interest with respect to the Securities of a series or related coupons without withholding or deductions until otherwise
advised. The Company covenants to indemnify the Trustee and any Paying Agent for, and to hold them harmless against, any loss, liability or expense reasonably incurred without negligence or bad faith on their part arising out of or in connection
with actions taken or omitted by any of them in reliance on any Officers’ Certificate furnished pursuant to this Section or in reliance on the Company’s not furnishing such an Officers’ Certificate. 
 Section 10.05. Statement as to Compliance. 
 (a) The Company will deliver to the Trustee, within 120 days after the end of each fiscal year ending after the date hereof so long as any Security is Outstanding hereunder, a brief

  

 68 

Table of Contents

 
certificate from the principal executive officer, principal financial officer or principal accounting officer of the Company as to his or her knowledge of the Company’s compliance with all
conditions and covenants under this Indenture. For purposes of this Section 10.05, such compliance shall be determined without regard to any period of grace or requirement of notice under this Indenture. 
 Section 10.06. Corporate Existence. 
 Subject to Article Eight, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect the corporate existence and related rights and franchises (charter and
statutory) of the Company and each of its Subsidiaries; provided, however, that the Company shall not be required to preserve any such right or franchise or the corporate existence of any such Subsidiary if the Board of Directors of
the Company shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and its Subsidiaries as a whole and that the loss thereof would not reasonably be expected to have a material adverse
effect on the ability of the Company to perform its obligations hereunder; and provided, further, however, that the foregoing shall not prohibit a sale, transfer or conveyance of a Subsidiary of the Company or any of its assets in compliance
with the terms of this Indenture. 
 Section 10.07. Waiver of Certain Covenants. 
 The Company may omit in any particular instance to comply with any covenants of the Company added to Article Ten pursuant to
Section 3.01(14) or Section 3.01(15) in connection with the Securities of a series, if before or after the time for such compliance the Holders of at least a majority in aggregate principal amount of all Outstanding Securities of such
series, by Act of such Holders, either waive such compliance in such instance or generally waive compliance with such covenant or condition, but no such waiver shall extend to or affect such covenant or condition except to the extent so expressly
waived, and, until such waiver shall become effective, the obligations of the Company and the duties of the Trustee in respect of any such covenant or condition shall remain in full force and effect. 
 ARTICLE ELEVEN 
 REDEMPTION OF SECURITIES 
 Section 11.01. Applicability of Article. 
 Securities of any series which are redeemable before their Stated Maturity shall be redeemable in accordance with their terms and (except as
otherwise specified as contemplated by Section 3.01 for Securities of any series) in accordance with this Article. 
 Section 11.02. 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. In case of any redemption at the election of the Company of less than all of the Securities of any series, the Company shall, at least 60 days prior to the Redemption Date fixed by the Company
(unless a shorter notice shall be satisfactory to the Trustee), notify the

  

 69 

Table of Contents

 
Trustee in writing of such Redemption Date and of the principal amount of Securities of such series to be redeemed, and, if applicable, of the tenor of the Securities to be redeemed, and shall
deliver to the Trustee such documentation and records as shall enable the Trustee to select the Securities to be redeemed pursuant to Section 11.03. In the case of any redemption of Securities of any series prior to the expiration of any
restriction on such redemption provided in the terms of such Securities or elsewhere in this Indenture, the Company shall furnish the Trustee with an Officers’ Certificate evidencing compliance with such restriction. 
 Section 11.03. Selection by Trustee of Securities to Be Redeemed. 
 If less than all the Securities of any series issued on the same day with the same terms are to be redeemed, the particular Securities to be
redeemed shall be selected not more than 60 days prior to the Redemption Date by the Trustee, from the Outstanding Securities of such series issued on such date with the same terms not previously called for redemption, by such method as the Trustee
shall deem fair and appropriate; provided that such method complies with the rules of any national securities exchange or quotation system on which the Securities are listed, and may provide for the selection for redemption of portions (equal
to the minimum authorized denomination for Securities of that series or any integral multiple thereof) of the principal amount of Securities of such series of a denomination larger than the minimum authorized denomination for Securities of that
series; provided, however, that no such partial redemption shall reduce the portion of the principal amount of a Security not redeemed to less than the minimum authorized denomination for Securities of such series. 
 The Trustee shall promptly notify the Company and the Security Registrar (if other than itself) in writing of the Securities selected for
redemption and, in the case of any Securities selected for partial redemption, the principal amount thereof to be redeemed. 
 For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities shall relate, in the case of any Security redeemed or to be redeemed only in part, to the portion of the
principal amount of such Security which has been or is to be redeemed. 
 Section 11.04. Notice of Redemption.

 Notice of redemption shall be given in the manner provided in Section 1.06, not less than 30 days nor more than 60
days prior to the Redemption Date, unless a shorter period is specified by the terms of such series established pursuant to Section 3.01, to each Holder of Securities to be redeemed, but failure to give such notice in the manner herein provided
to the Holder of any Security designated for redemption as a whole or in part, or any defect in the notice to any such Holder, shall not affect the validity of the proceedings for the redemption of any other such Security or portion thereof.

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

part only, the notice which relates to such Security shall state that on and after the Redemption Date, upon surrender of such Security, the Holder will receive, without a charge, a new Security or Securities of authorized denominations for the
principal amount thereof remaining unredeemed; 
 (5) that on the Redemption Date, the Redemption Price and accrued interest, if
any, to the Redemption Date payable as provided in Section 11.06 will become due and payable upon each such Security, or the portion thereof, to be redeemed and, if applicable, that interest thereon shall cease to accrue on and after said date;

 (6) the Place or Places of Payment where such Securities, together in the case of Bearer Securities with all coupons
appertaining thereto, if any, maturing after the Redemption Date, are to be surrendered for payment of the Redemption Price and accrued interest, if any; 
 (7) that the redemption is for a sinking fund, if such is the case; 
 (8) that,
unless otherwise specified in such notice, Bearer Securities of any series, if any, surrendered for redemption must be accompanied by all coupons maturing subsequent to the Redemption Date or the amount of any such missing coupon or coupons will be
deducted from the Redemption Price, unless security or indemnity satisfactory to the Company, the Trustee for such series and any Paying Agent is furnished; 
 (9) if Bearer Securities of any series are to be redeemed and any Registered Securities of such series are not to be redeemed, and if such Bearer Securities may be exchanged for Registered Securities not
subject to redemption on this Redemption Date pursuant to Section 3.05 or otherwise, the last date, as determined by the Company, on which such exchanges may be made; and 
 (10) the CUSIP number of such Security, if any. 
 A notice of redemption published as contemplated by Section 1.06 need not identify particular Registered Securities to be redeemed. Notice of redemption of Securities to be redeemed shall be given by
the Company or, at the Company’s request, by the Trustee in the name and at the expense of the Company. 
 Section
11.05. Deposit of Redemption Price. 
 On or prior to 10:00 a.m., New York City time, on any Redemption Date, the Company

Table of Contents

 
Paying Agent, which it may not do in the case of a sinking fund payment under Article Twelve, segregate and hold in trust as provided in Section 10.03) an amount of money in the Currency in
which the Securities of such series are payable (except as otherwise specified pursuant to Section 3.01 for the Securities of such series and except, if applicable, as provided in Sections 3.12(b), 3.12(d) and 3.12(e)) sufficient to pay on the
Redemption Date the Redemption Price of, and (unless otherwise specified pursuant to Section 3.01) accrued interest on, all the Securities or portions thereof which are to be redeemed on that date. 
 Section 11.06. Securities Payable on Redemption Date. 
 Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified in the Currency in
which the Securities of such series are payable (except as otherwise specified pursuant to Section 3.01 for the Securities of such series and except, if applicable, as provided in Sections 3.12(b), 3.12(d) and 3.12(e)) (together with accrued
interest, if any, to the Redemption Date), and from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued interest, if any) such Securities shall if the same were interest-bearing cease to bear
interest and the coupons for such interest appertaining to any Bearer Securities so to be redeemed, except to the extent provided below, shall be void. Upon surrender of any such Security for redemption in accordance with said notice, together with
all coupons, if any, appertaining thereto maturing after the Redemption Date, such Security shall be paid by the Company at the Redemption Price, together with accrued interest, if any, to the Redemption Date; provided, however, that
installments of interest on Bearer Securities whose Stated Maturity is on or prior to the Redemption Date shall be payable only at an office or agency located outside the United States (except as otherwise provided in Section 10.02) and, unless
otherwise specified as contemplated by Section 3.01, only upon presentation and surrender of coupons for such interest; and provided further that, unless otherwise specified as contemplated by Section 3.01, installments of interest
on Registered Securities whose Stated Maturity is on or prior to the Redemption Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the relevant Record Dates
according to their terms and the provisions of Section 3.07. 
 If any Bearer Security surrendered for redemption shall not
be accompanied by all appurtenant coupons maturing after the Redemption Date, such Security may be paid after deducting from the Redemption Price an amount equal to the face amount of all such missing coupons, or the surrender of such missing coupon
or coupons may be waived by the Company and the Trustee if there be furnished to them such security or indemnity as they may require to save each of them and any Paying Agent harmless. If thereafter the Holder of such Security shall surrender to the
Trustee or any Paying Agent any such missing coupon in respect of which a deduction shall have been made from the Redemption Price, such Holder shall be entitled to receive the amount so deducted; provided, however, that interest
represented by coupons shall be payable only at an office or agency located outside the United States (except as otherwise provided in Section 10.02) and, unless otherwise specified as contemplated by Section 3.01, only upon presentation
and surrender of those coupons. 
 If any Security called for redemption shall not be so paid upon surrender thereof for
redemption, the Redemption Price shall, until paid, bear interest from the Redemption Date at the

rate of interest set forth in such Security or, in the case of an Original Issue Discount Security, at the Yield to Maturity of such Security. 
 Section 11.07. Securities Redeemed in Part. 
 Any Registered Security which is to be redeemed only in part (pursuant to the provisions of this Article or of Article Twelve) shall be surrendered at a Place of Payment therefor (with, if the Company or
the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or such Holder’s attorney duly authorized in writing) and the Company
shall execute and the Trustee shall authenticate and deliver to the Holder of such Security without service charge a new Security or Securities of the same series and of like tenor, of any authorized denomination as requested by such Holder in
aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Security so surrendered. If a temporary global Security or permanent global Security is so surrendered, such new Security so issued shall be a new
temporary global Security or permanent global Security, respectively. However, if less than all the Securities of any series with differing issue dates, interest rates and stated maturities are to be redeemed, the Company in its sole discretion
shall select the particular Securities to be redeemed and shall notify the Trustee in writing thereof at least 45 days prior to the relevant redemption date. 
 Section 11.08. Repurchases on the Open Market. 
 The Company or any
Affiliate of the Company may at any time or from time to time repurchase any of the Securities in the open market or otherwise. Such Securities may, at the option of the Company or the relevant Affiliate of the Company, be held, resold or
surrendered to the Trustee for cancellation. 
 ARTICLE TWELVE 
 SINKING FUNDS 
 Section 12.01. Applicability of
Article. 
 The provisions of this Article shall be applicable to any sinking fund for the retirement of Securities of a
series except as otherwise specified as contemplated by Section 3.01 for Securities of such series. 
 The minimum amount
of any sinking fund payment provided for by the terms of Securities of any series is herein referred to as a “mandatory sinking fund payment”, and any payment in excess of such minimum amount provided for by the terms of such Securities of
any series is herein referred to as an “optional sinking fund payment”. If provided for by the terms of any Securities of any series, the cash amount of any mandatory sinking fund payment may be subject to reduction as provided in

 Section 12.02. Satisfaction of Sinking Fund Payments with Securities. 
 The Company may, in satisfaction of all or any part of any mandatory sinking fund payment with respect to the Securities of a series,
(1) deliver Outstanding Securities of such series (other than any previously called for redemption) together in the case of any Bearer Securities of such series with all unmatured coupons appertaining thereto and (2) apply as a credit
Securities of such series which have been redeemed either at the election of the Company pursuant to the terms of such Securities or through the application of permitted optional sinking fund payments pursuant to the terms of such Securities, as
provided for by the terms of such Securities; provided that such Securities so delivered or applied as a credit have not been previously so credited. Such Securities shall be received and credited for such purpose by the Trustee at the
applicable Redemption Price specified in such Securities for redemption through operation of the sinking fund and the amount of such mandatory sinking fund payment shall be reduced accordingly. 
 Section 12.03. Redemption of Securities for Sinking Fund. 
 Not less than 60 days prior to each sinking fund payment date for Securities of any series, the Company will deliver to the Trustee an
Officers’ Certificate specifying the amount of the next ensuing mandatory sinking fund payment for that series pursuant to the terms of that series, the portion thereof, if any, which is to be satisfied by payment of cash in the Currency in
which the Securities of such series are payable (except as otherwise specified pursuant to Section 3.01 for the Securities of such series and except, if applicable, as provided in Sections 3.12(b), 3.12(d) and 3.12(e)) and the portion thereof,
if any, which is to be satisfied by delivering and crediting Securities of that series pursuant to Section 12.02, and the optional amount, if any, to be added in cash to the next ensuing mandatory sinking fund payment, and will also deliver to
the Trustee any Securities to be so delivered and credited. If such Officers’ Certificate shall specify an optional amount to be added in cash to the next ensuing mandatory sinking fund payment, the Company shall thereupon be obligated to pay
the amount therein specified. Not less than 30 days before each such sinking fund payment date the Trustee shall select the Securities to be redeemed upon such sinking fund payment date in the manner specified in Section 11.03 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 11.04. Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner
stated in Sections 11.06 and 11.07.

 74 

Table of Contents

 Section 13.02. Repayment of Securities. 
 Securities of any series subject to repayment in whole or in part at the option of the Holders thereof will, unless otherwise provided in
the terms of such Securities, be repaid at the Repayment Price thereof, together with interest, if any, thereon accrued to the Repayment Date specified in or pursuant to the terms of such Securities. The Company covenants that on or before 10:00
a.m., New York City time, on the Repayment Date it will deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 10.03) an amount of money in the
Currency in which the Securities of such series are payable (except as otherwise specified pursuant to Section 3.01 for the Securities of such series and except, if applicable, as provided in Sections 3.12(b), 3.12(d) and 3.12(e)) sufficient to
pay the Repayment Price of, and (unless otherwise specified pursuant to Section 3.01) accrued interest on, all the Securities or portions thereof, as the case may be, to be repaid on such date. 
 Section 13.03. Exercise of Option. 
 Securities of any series subject to repayment at the option of the Holders thereof will contain an “Option to Elect Repayment” form on the reverse of such Securities. To be repaid at the option
of the Holder, any Security so providing for such repayment, with the “Option to Elect Repayment” form on the reverse of such Security duly completed by the Holder (or by the Holder’s attorney duly authorized in writing), must be
received by the Company at the Place of Payment therefor specified in the terms of such Security (or at such other place or places of which the Company shall from time to time notify the Holders of such Securities) not earlier than 45 days nor later
than 30 days prior to the Repayment Date. If less than the entire Repayment Price of such Security is to be repaid in accordance with the terms of such Security, the portion of the Repayment Price of such Security to be repaid, in increments of the
minimum denomination for Securities of such series, and the denomination or denominations of the Security or Securities to be issued to the Holder for the portion of such Security surrendered that is not to be repaid, must be specified. Any Security
providing for repayment at the option of the Holder thereof may not be repaid in part if, following such repayment, the unpaid principal amount of such Security would be less than the minimum authorized denomination of Securities of the series of
which such Security to be repaid is a part. Except as otherwise may be provided by the terms of any Security providing for repayment at the option of the Holder thereof, exercise of the repayment option by the Holder shall be irrevocable unless
waived by the Company. 
 Section 13.04. When Securities Presented for Repayment Become Due and Payable. 
 If Securities of any series providing for repayment at the option of the Holders thereof shall have been surrendered as provided in this
Article and as provided by or pursuant to the terms of such Securities, such Securities or the portions thereof, as the case may be, to be repaid shall become due and payable and shall be paid by the Company on the Repayment Date therein specified,
and on and after such Repayment Date (unless the Company shall default in the payment of such Securities on such Repayment Date) such Securities shall, if the same were interest-bearing, cease to bear interest and the coupons for such interest
appertaining to any Bearer Securities so to be repaid, except to the extent provided below, shall be void. Upon

  

 75 

Table of Contents

 
surrender of any such Security for repayment in accordance with such provisions, together with all coupons, if any, appertaining thereto maturing after the Repayment Date, the Repayment Price of
such Security so to be repaid shall be paid by the Company, together with accrued interest, if any, to the Repayment Date; provided, however, that coupons whose Stated Maturity is on or prior to the Repayment Date shall be payable only
at an office or agency located outside the United States (except as otherwise provided in Section 10.02) and, unless otherwise specified pursuant to Section 3.01, only upon presentation and surrender of such coupons; and provided
further that installments of interest on Registered Securities, whose Stated Maturity is prior to (or, if specified pursuant to Section 3.01, on) the Repayment Date shall be payable (but without interest thereon, unless the Company shall
default in the payment thereof) to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the relevant Record Dates according to their terms and the provisions of Section 3.07.

 If any Bearer Security surrendered for repayment shall not be accompanied by all appurtenant coupons maturing after the
Repayment Date, such Security may be paid after deducting from the amount payable therefor as provided in Section 13.02 an amount equal to the face amount of all such missing coupons, or the surrender of such missing coupon or coupons may be
waived by the Company and the Trustee if there be furnished to them such security or indemnity as they may require to save each of them and any Paying Agent harmless. If thereafter the Holder of such Security shall surrender to the Trustee or any
Paying Agent any such missing coupon in respect of which a deduction shall have been made as provided in the preceding sentence, such Holder shall be entitled to receive the amount so deducted; provided, however, that interest
represented by coupons shall be payable only at an office or agency located outside the United States (except as otherwise provided in Section 10.02) and, unless otherwise specified as contemplated by Section 3.01, only upon presentation
and surrender of those coupons. 
 If any Security surrendered for repayment shall not be so repaid upon surrender thereof, the
Repayment Price shall, until paid, bear interest from the Repayment Date at the rate of interest set forth in such Security or, in the case of an Original Issue Discount Security, at the Yield to Maturity of such Security. 
 Section 13.05. Securities Repaid in Part. 
 Upon surrender of any Registered Security which is to be repaid in part only, the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Security, without service
charge and at the expense of the Company, a new Registered Security or Securities of the same series, and of like tenor, of any authorized denomination specified by the Holder, in an aggregate principal amount equal to and in exchange for the
portion of the principal of such Security so surrendered which is not to be repaid. If a temporary global Security or permanent global Security is so surrendered, such new Security so issued shall be a new temporary global Security or a new
permanent global Security, respectively.

 If pursuant to
Section 3.01 provision is made for either or both of (a) defeasance of the Securities of or within a series under Section 14.02 or (b) covenant defeasance of the Securities of or within a series under Section 14.03, then the
provisions of such Section or Sections, as the case may be, together with the other provisions of this Article (with such modifications thereto as may be specified pursuant to Section 3.01 with respect to any Securities), shall be applicable to
such Securities and any coupons appertaining thereto, and the Company may at its option by Board Resolution, at any time, with respect to such Securities and any coupons appertaining thereto, elect to have either Section 14.02 (if applicable)
or Section 14.03 (if applicable) be applied to such Outstanding Securities and any coupons appertaining thereto upon compliance with the conditions set forth below in this Article. 
 Section 14.02. Defeasance and Discharge. 
 Upon the Company’s exercise of the above option applicable to this Section with respect to any Securities of or within a series, the Company shall be deemed to have been discharged from its
obligations with respect to such Outstanding Securities and any coupons appertaining thereto on and after the date the conditions set forth in Section 14.04 are satisfied (hereinafter, “defeasance”). For this purpose, such defeasance
means that the Company shall be deemed to have paid and discharged the entire indebtedness represented by such Outstanding Securities and any coupons appertaining thereto, which shall thereafter be deemed to be “Outstanding” only for the
purposes of Section 14.05 and the other Sections of this Indenture referred to in clauses (A) and (B) of this Section, and to have satisfied all its other obligations under such Securities and any coupons appertaining thereto and this
Indenture insofar as such Securities and any coupons appertaining thereto are concerned (and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following which shall survive until
otherwise terminated or discharged hereunder: (A) the rights of Holders of such Outstanding Securities and any coupons appertaining thereto to receive, solely from the trust fund described in Section 14.04 and as more fully set forth in
such Section, payments in respect of the principal of (and premium, if any) and interest, if any, on such Securities and any coupons appertaining thereto when such payments are due, (B) the Company’s obligations with respect to such
Securities under Sections 3.05, 3.06, 10.02 and 10.03 and with respect to the payment of Additional Amounts, if any, on such Securities as contemplated by Section 10.04, (C) the rights, powers, trusts, duties and immunities of the Trustee
hereunder and (D) this Article. Subject to compliance with this Article Fourteen, the Company may exercise its option under this Section notwithstanding the prior exercise of its option under Section 14.03 with respect to such Securities
and any coupons appertaining thereto. Following a defeasance, payment of such Securities may not be accelerated because of an Event of Default. 
 Section 14.03. Covenant Defeasance. 
 Upon the Company’s exercise of
the above option applicable to this Section with respect to any Securities of or within a series, the Company shall be released from its obligations under any covenant, with respect to such Outstanding Securities and any coupons appertaining thereto
on and after the date the conditions set forth in Section 14.04 are satisfied (hereinafter, “covenant

  

 77 

Table of Contents

 
defeasance”), and such Securities and any coupons appertaining thereto shall thereafter be deemed to be not “Outstanding” for the purposes of any direction, waiver, consent or
declaration or Act of Holders (and the consequences of any thereof) in connection with such other covenant, but shall continue to be deemed “Outstanding” for all other purposes hereunder. For this purpose, such covenant defeasance means
that, with respect to such Outstanding Securities and any coupons appertaining thereto, the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such Section or such other
covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such Section or such other covenant or by reason of reference in any such Section or such other covenant to any other provision herein or in any other
document and such omission to comply shall not constitute a Default or an Event of Default under Section 5.01(4) or 5.01(7) or otherwise, as the case may be, but, except as specified above, the remainder of this Indenture and such Securities
and any coupons appertaining thereto shall be unaffected thereby. Following a covenant defeasance, payment of such Securities may not be accelerated because of an Event of Default solely by reference to such Sections specified above in this
Section 14.03. 
 Section 14.04. Conditions to Defeasance or Covenant Defeasance. 
 The following shall be the conditions to application of either Section 14.02 or Section 14.03 to any Outstanding Securities of or
within a series and any coupons appertaining thereto: 
 (a) The Company shall have irrevocably deposited or caused to be
irrevocably deposited with the Trustee (or another trustee satisfying the requirements of Section 6.07 who shall agree to comply with the provisions of this Article Fourteen applicable to it) as trust funds in trust for the purpose of making
the following payments, specifically pledged as security for the benefit of, and dedicated solely to, the Holders of such Securities and any coupons appertaining thereto, (1) an amount (in such Currency in which such Securities and any coupons
appertaining thereto are then specified as payable at Stated Maturity), or (2) Government Obligations applicable to such Securities and coupons appertaining thereto (determined on the basis of the Currency in which such Securities and coupons
appertaining thereto are then specified as payable at Stated Maturity) which through the scheduled payment of principal and interest in respect thereof in accordance with their terms will provide, not later than one day before the due date of any
payment of principal of (and premium, if any) and interest, if any, on such Securities and any coupons appertaining thereto, money in an amount or (3) a combination thereof in an amount, sufficient, in the opinion of a nationally recognized
firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, to pay and discharge, and which shall be applied by the Trustee (or other qualifying trustee) to pay and discharge, (i) the principal
of (and premium, if any) and interest, if any, on such Outstanding Securities and any coupons appertaining thereto on the Stated Maturity of such principal or installment of principal or interest and (ii) any mandatory sinking fund payments or
analogous payments applicable to such Outstanding Securities and any coupons appertaining thereto on the day on which such payments are due and payable in accordance with the terms of this Indenture and of such Securities and any coupons
appertaining thereto. 
 (b) 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. 
  

 78 

Table of Contents

 (c) No Default or Event of Default with respect to such Securities and any coupons
appertaining thereto shall have occurred and be continuing on the date of such deposit or, insofar as Sections 5.01(5) and 5.01(6) are concerned, at any time during the period ending on the 91st day after the date of such deposit (it being
understood that this condition shall not be deemed satisfied until the expiration of such period). 
 (d) In the case of an
election under Section 14.02, the Company shall have delivered to the Trustee an Opinion of Counsel stating that (i) the Company has received from, or there has been published by, the Internal Revenue Service a ruling or (ii) since
the date of execution of this Indenture, there has been a change in the applicable Federal income tax law, in either case to the effect that, and based thereon such opinion shall confirm that, the Holders of such Outstanding Securities and any
coupons appertaining thereto will not recognize income, gain or loss for Federal income tax purposes as a result of such defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have
been the case if such defeasance had not occurred. 
 (e) In the case of an election under Section 14.03, the Company shall
have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of such Outstanding Securities and any coupons appertaining thereto will not recognize income, gain or loss for Federal income tax purposes as a result of such
covenant defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such covenant defeasance had not occurred. 
 (f) The Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all
conditions precedent to either the defeasance under Section 14.02 or the covenant defeasance under Section 14.03 (as the case may be) have been complied with and an Opinion of Counsel to the effect that either (i) as a result of a
deposit pursuant to subsection (a) above and the related exercise of the Company’s option under Section 14.02 or Section 14.03 (as the case may be), registration is not required under the Investment Company Act of 1940, as
amended, by the Company, with respect to the trust funds representing such deposit or by the trustee for such trust funds or (ii) all necessary registrations under said Act have been effected. 
 (g) Notwithstanding any other provisions of this Section, such defeasance or covenant defeasance shall be effected in compliance with any
additional or substitute terms, conditions or limitations which may be imposed on the Company in connection therewith pursuant to Section 3.01. 
 Section 14.05. Deposited Money and Government Obligations to Be Held in Trust; Other Miscellaneous Provisions. 
 Subject to the provisions of the last paragraph of Section 10.03, all money and Government Obligations (or other property as may be provided pursuant to Section 3.01) (including the proceeds
thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 14.05, the “Trustee”) pursuant to Section 14.04 in respect of any Outstanding Securities of any series and any coupons
appertaining thereto shall be held in trust and applied by the Trustee, in accordance with the provisions of such Securities and

  

 79 

Table of Contents

 
any coupons appertaining thereto and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Holders of such Securities and any coupons appertaining thereto of all sums due and to become due thereon in respect of principal (and premium, if any) and interest, if any, but such money need not be segregated from other funds
except to the extent required by law. 
 Unless otherwise specified with respect to any Security pursuant to Section 3.01,
if, after a deposit referred to in Section 14.04(a) has been made, (a) the Holder of a Security in respect of which such deposit was made is entitled to, and does, elect pursuant to Section 3.12(b) or the terms of such Security to
receive payment in a Currency other than that in which the deposit pursuant to Section 14.04(a) has been made in respect of such Security or (b) a Conversion Event occurs as contemplated in Section 3.12(d) or 3.12(e) or by the terms
of any Security in respect of which the deposit pursuant to Section 14.04(a) has been made, the indebtedness represented by such Security and any coupons appertaining thereto shall be deemed to have been, and will be, fully discharged and
satisfied through the payment of the principal of (and premium, if any) and interest, if any, on such Security as the same becomes due out of the proceeds yielded by converting (from time to time as specified below in the case of any such election)
the amount or other property deposited in respect of such Security into the Currency in which such Security becomes payable as a result of such election or Conversion Event based on the applicable Market Exchange Rate for such Currency in effect on
the second Business Day prior to each payment date, except, with respect to a Conversion Event, for such Currency in effect (as nearly as feasible) at the time of the Conversion Event. 
 The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the money or Government
Obligations deposited pursuant to Section 14.04 or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of such Outstanding Securities and any coupons
appertaining thereto. 
 Anything in this Article to the contrary notwithstanding, the Trustee shall deliver or pay to the
Company from time to time upon Company Request any money or Government Obligations (or other property and any proceeds therefrom) held by it as provided in Section 14.04 which, in the opinion of a nationally recognized firm of independent
public accountants expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect a defeasance or covenant defeasance, as applicable, in accordance
with this Article.

 The Company, for itself, its successors and assigns, covenants and agrees, and each Holder of Senior Subordinated

in the manner hereinafter set forth, in right of payment to the prior payment in full of all Senior Indebtedness. 
 The Company, for itself, its successors and assigns, covenants and agrees, and each Holder of Junior Subordinated Securities by his acceptance thereof, likewise covenants and agrees, that the payment of
the principal of (and premium, if any) and interest, if any, on each and all of the Junior Subordinated Securities is hereby expressly subordinated, to the extent and in the manner hereinafter set forth, in right of payment to the prior payment in
full of all Senior Indebtedness and Senior Subordinated Indebtedness. 
 Section 15.02. Distribution on Dissolution,
Liquidation and Reorganization; Subrogation of Subordinated Securities. 
 Upon any distribution of assets of the Company
upon any dissolution, winding up, liquidation or reorganization of the Company, whether in bankruptcy, insolvency, reorganization or receivership proceedings or upon an assignment for the benefit of creditors or any other marshalling of the assets
and liabilities of the Company or otherwise (subject to the power of a court of competent jurisdiction to make other equitable provision reflecting the rights conferred in this Indenture upon the Senior Indebtedness and the holders thereof with
respect to the Securities and the holders thereof by a lawful plan of reorganization under applicable bankruptcy law): 
 (a)
the holders of all Senior Indebtedness shall be entitled to receive payment in full of the principal thereof (and premium, if any) and interest due thereon before the Holders of the Subordinated Securities are entitled to receive any payment upon
the principal (or premium, if any) or interest, if any, on indebtedness evidenced by the Subordinated Securities; 
 (b) the
holders of all Senior Subordinated Indebtedness shall be entitled to receive payment in full of the principal thereof (and premium, if any) and interest due thereon before the Holders of the Junior Subordinated Securities are entitled to receive any
payment upon the principal (or premium, if any) or interest, if any, on indebtedness evidenced by the Junior Subordinated Securities; 
 (c) any payment or distribution of assets of the Company of any kind or character, whether in cash, property or securities, to which the Holders of the Securities or the Trustee would be entitled except for the provisions of this Article
Fifteen shall be paid by the liquidating trustee or agent or other person making such payment or distribution, whether a trustee in bankruptcy, a receiver or liquidating trustee or otherwise, directly to the holders of Senior Indebtedness or their
representative or representatives or to the trustee or trustees under any indenture under which any instruments evidencing any of such Senior Indebtedness may have been issued, ratably according to the aggregate amounts remaining unpaid on account
of the principal of (and premium, if any) and interest on the Senior Indebtedness held or represented by each, to the extent necessary to make payment in full of all Senior Indebtedness remaining unpaid, after giving effect to any concurrent payment
or distribution to the holders of such Senior Indebtedness; and 
  

 81 

Table of Contents

 (d) in the event that, notwithstanding the foregoing, any payment or distribution of assets
of the Company of any kind or character, whether in cash, property or securities, shall be received by the Trustee or the Holders of the Subordinated Securities before all Senior Indebtedness is paid in full, such payment or distribution shall be
paid over, upon written notice to the Trustee, to the holder of such Senior Indebtedness or their representative or representatives or to the trustee or trustees under any indenture under which any instrument evidencing any of such Senior
Indebtedness may have been issued, ratably as aforesaid, for application to payment of all Senior Indebtedness remaining unpaid until all such Senior Indebtedness shall have been paid in full, after giving effect to any concurrent payment or
distribution to the holders of such Senior Indebtedness. 
 Subject to the payment in full of all Senior Indebtedness, the
Holders of the Subordinated Securities shall be subrogated to the rights of the holders of Senior Indebtedness to receive payments or distributions of cash, property or securities of the Company applicable to Senior Indebtedness until the principal
of (and premium, if any) and interest, if any, on the Subordinated Securities shall be paid in full and no such payments or distributions to the Holders of the Subordinated Securities of cash, property or securities otherwise distributable to the
holders of Senior Indebtedness shall, as between the Company, its creditors other than the holders of Senior Indebtedness, and the Holders of the Subordinated Securities be deemed to be a payment by the Company to or on account of the Subordinated
Securities. It is understood that the provisions of this Article Fifteen are and are intended solely for the purpose of defining the relative rights of the Holders of the Subordinated Securities, on the one hand, and the holders of the Senior
Indebtedness, on the other hand. Nothing contained in this Article Fifteen or elsewhere in this Indenture or in the Subordinated Securities is intended to or shall impair, as between the Company, its creditors other than the holders of Senior
Indebtedness, and the Holders of the Subordinated Securities, the obligation of the Company, which is unconditional and absolute, to pay to the Holders of the Subordinated Securities the principal of (and premium, if any) and interest, if any, on
the Subordinated Securities as and when the same shall become due and payable in accordance with their terms, or to affect the relative rights of the Holders of the Subordinated Securities and creditors of the Company other than the holders of
Senior Indebtedness, nor shall anything herein or in the Subordinated Securities prevent the Trustee or the Holder of any Subordinated Security from exercising all remedies otherwise permitted by applicable law upon default under this Indenture,
subject to the rights, if any, under this Article Fifteen of the holders of Senior Indebtedness in respect of cash, property or securities of the Company received upon the exercise of any such remedy. Upon any payment or distribution of assets of
the Company referred to in this Article Fifteen, the Trustee, subject to the provisions of Section 6.01, shall be entitled to rely upon a certificate of the liquidating trustee or agent or other person making any distribution to the Trustee for
the purpose of ascertaining the Persons entitled to participate in such distribution, the holders of Senior Indebtedness and other indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon
and all other facts pertinent thereto or to this Article Fifteen. 
 If the Trustee or any Holder of Subordinated Securities
does not file a proper claim or proof of debt in the form required in any proceeding referred to above prior to 30 days before the expiration of the time to file such claim in such proceeding, then the holder of any Senior Indebtedness is hereby
authorized, and has the right, to file an appropriate claim or claims for or on behalf of such Holder of Subordinated Securities. 
  

 82 

Table of Contents

 With respect to the holders of Senior Indebtedness, the Trustee undertakes to perform or to
observe only such of its covenants or obligations as are specifically set forth in this Article and no implied covenants or obligations with respect to holders of Senior Indebtedness shall be read into this Indenture against the Trustee. The Trustee
does not owe any fiduciary duties to the holders of Securities other than Securities issued under this Indenture. 
 Section
15.03. No Payment on Subordinated Securities in Event of Default on Senior Indebtedness. 
 No payment by the Company on
account of principal (or premium, if any), sinking funds or interest, if any, on the Subordinated Securities shall be made unless full payment of amounts then due for principal (premium, if any), sinking funds and interest on Senior Indebtedness has
been made or duly provided for in money or money’s worth. 
 Section 15.04. Payments on Subordinated Securities
Permitted. 
 Nothing contained in this Indenture or in any of the Subordinated Securities shall (a) affect the
obligation of the Company to make, or prevent the Company from making, at any time except as provided in Sections 15.02 and 15.03, payments of principal of (or premium, if any) or interest, if any, on the Subordinated Securities or (b) prevent
the application by the Trustee of any moneys deposited with it hereunder to the payment of or on account of the principal of (or premium, if any) or interest, if any, on the Subordinated Securities, unless the Trustee shall have received at its
Corporate Trust Office written notice of any event prohibiting the making of such payment more than three Business Days prior to the date fixed for such payment. 
 Section 15.05. Authorization of Holders to Trustee to Effect Subordination. 
 Each Holder of Subordinated Securities by his acceptance thereof authorizes and directs the Trustee on his behalf to take such action as may be necessary or appropriate to effectuate the subordination as provided in this Article Fifteen and
appoints the Trustee his attorney-in-fact for any and all such purposes. 
 Section 15.06. Notices to Trustee.

 Notwithstanding the provisions of this Article or any other provisions of this Indenture, neither the Trustee nor any
Paying Agent (other than the Company) shall be charged with knowledge of the existence of any Senior Indebtedness or of any event which would prohibit the making of any payment of moneys to or by the Trustee or such Paying Agent, unless and until
the Trustee or such Paying Agent shall have received (in the case of the Trustee, at its Corporate Trust Office) written notice thereof from the Company or from the holder of any Senior Indebtedness or from the trustee for any such holder, together
with proof satisfactory to the Trustee of such holding of Senior Indebtedness or of the authority of such trustee; provided, however, that if at least three Business Days prior to the date upon which by the terms hereof any such moneys
may become payable for any purpose (including, without limitation, the payment of either the principal (or premium, if any) or interest, if any, on any Subordinated Security) the Trustee shall not have received with respect to such moneys the notice
provided for in this Section 15.06, then, anything herein contained to the contrary notwithstanding, the Trustee shall have full power and authority to receive such moneys and to apply the same to the purpose for

  

 83 

Table of Contents

 
which they were received, and shall not be affected by any notice to the contrary, which may be received by it within three Business Days prior to such date. The Trustee shall be entitled to rely
on the delivery to it of a written notice by a Person representing himself to be a holder of Senior Indebtedness (or a trustee on behalf of such holder) to establish that such a notice has been given by a holder of Senior Indebtedness or a trustee
on behalf of any such holder. In the event that the Trustee determines in good faith that further evidence is required with respect to the right of any Person as a holder of Senior Indebtedness to participate in any payment or distribution pursuant
to this Article Fifteen, the Trustee may request such Person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness held by such Person, the extent to which such Person is entitled to participate in
such payment or distribution and any other facts pertinent to the rights of such Person under this Article Fifteen and, if such evidence is not furnished, the Trustee may defer any payment to such Person pending judicial determination as to the
right of such Person to receive such payment. 
 Section 15.07. Trustee as Holder of Senior Indebtedness. 
 The Trustee in its individual capacity shall be entitled to all the rights set forth in this Article Fifteen in respect of any Senior
Indebtedness at any time held by it to the same extent as any other holder of Senior Indebtedness and nothing in Section 6.13 or elsewhere in this Indenture shall be construed to deprive the Trustee of any of its rights as such holder.

 Nothing in this Article Fifteen shall apply to claims of, or payments to, the Trustee under or pursuant to Section 6.06.

 Section 15.08. Modifications of Terms of Senior Indebtedness. 
 Any renewal or extension of the time of payment of any Senior Indebtedness or the exercise by the holders of Senior Indebtedness of any of
their rights under any instrument creating or evidencing Senior Indebtedness, including, without limitation, the waiver of default thereunder, may be made or done all without notice to or assent from the Holders of the Subordinated Securities or the
Trustee. 
 No compromise, alteration, amendment, modification, extension, renewal or other change of, or waiver, consent or
other action in respect of, any liability or obligation under or in respect of, or of any of the terms, covenants or conditions of any indenture or other instrument under which any Senior Indebtedness is outstanding or of such Senior Indebtedness,
whether or not such release is in accordance with the provisions of any applicable document, shall in any way alter or affect any of the provisions of this Article Fifteen or of the Subordinated Securities relating to the subordination thereof.

 Section 15.09. Reliance on Judicial Order or Certificate of Liquidating Agent. 
 Upon any payment or distribution of assets of the Company referred to in this Article Fifteen, the Trustee and the Holders of the Securities
shall be entitled to rely upon any order or decree entered by any court of competent jurisdiction in which such insolvency, bankruptcy, receivership, liquidation, reorganization, dissolution, winding up or similar case or proceeding is pending, or a
certificate of the trustee in bankruptcy, liquidating trustee, custodian, receiver, assignee for the benefit of creditors, agent or other person making such payment or distribution,

 REVERSE SIDE OF FORM OF DEBT SECURITY 
 UNIGENE LABORATORIES, INC. 
  

	 	1.	Indenture. 

 This Security is
one of a duly authorized issue of debt securities of Unigene Laboratories, Inc., a Delaware corporation (such corporation, and its successors and assigns under the Indenture, the “Company”), designated as its
“[            ] Notes due [            ]” (the “Securities”), issued under an indenture dated as of
[            ] (as amended or supplemented from time to time, the “Indenture”) between the Company and
[            ], as trustee (the “Trustee”, which term includes any successor Trustee under the Indenture), to which Indenture reference is hereby made for a statement of
the respective rights, limitations of rights, duties and immunities thereunder of the Company, Trustee and each Holder of Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. The summary of the terms
of this Security contained herein does not purport to be complete and is qualified by reference to the Indenture. All terms used in this Security which are not defined herein shall have the same meanings assigned to them in the Indenture.

  

	 	2.	Principal and Interest. 

 The
Company promises to pay $[            ] to the Holder hereof on [            ]. 
 All computations of interest shall be made on the basis of a 360-day year consisting of twelve 30-day months. 
  

	 	3.	Method of Payment. 

 The
Company, through the Paying Agent, shall pay interest on this Security to the registered Holder of this Security, as provided above. The Holder must surrender this Security to a Paying Agent to collect principal payments. The Company will pay
principal and interest in money of the United States of America that at the time of payment is legal tender for payment of all debts public and private. Principal and interest will be payable at the office of the Paying Agent but, at the option of
the Company, interest may be paid by check mailed to the registered Holders at their registered addresses. 
  

	 	4.	Transfer Agent, Paying Agent and Registrar.

 [Describe

	 	6.	Transfer and Exchange.

Table of Contents

 A Holder may transfer a Security upon the surrender of such Security for registration of
transfer. No such transfer shall be effected until, and such transferee shall succeed to the rights of a Holder only upon, final acceptance and registration of this transfer in the Security Register by the Registrar. When Securities are presented to
the Registrar with a request to register the transfer of, or to exchange, such Securities, the Registrar shall register the transfer or make such exchange as requested if its requirements for such transactions and any applicable requirements
hereunder are satisfied. 
 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 of Securities. 
  

	 	7.	Denominations. 

 The Securities
are issuable in registered form in denominations of $1,000 and integral multiples thereof. 
  

	 	8.	Unclaimed Money. 

 If money for
the payment of principal or interest remains unclaimed for two years, the Trustee or Paying Agent shall pay the money back to the Company at its request unless an abandoned property law designates another Person. After any such payment, Holders
entitled to the money must look only to the Company and not to the Trustee for payment unless such abandoned property law designates another Person. 
  

	 	9.	Discharge and Defeasance. 

 Subject to certain conditions, the Company at any time may terminate some or all of its obligations under the Securities and the Indenture if the Company irrevocably deposits with the Trustee money or U.S. Government Obligations for the
payment of principal and interest on the Securities to redemption or maturity, as the case may be. 
  

	 	10.	Amendment, Waiver. 

 Subject to
certain exceptions set forth in the Indenture, (i) the Indenture or the Securities may be amended with the written consent of the Holders of at least a majority in aggregate principal amount of the Outstanding Securities and (ii) any past
Default and its consequences may be waived with the written consent of the Holders of at least a majority in principal amount of the Outstanding Securities except a default (1) in the payment of the principal of (or premium, if any) or
interest, if any, on any Security of such series or any related coupons, or (2) in respect of a covenant or provision of the Indenture which cannot be modified or amended without the consent of the Holder of each Outstanding Security of such
series affected. Subject to certain exceptions set forth in the Indenture, without the consent of any Holder of Securities, the Company and the Trustee may amend the Indenture or the Securities (i) to evidence the succession of another Person

powers conferred on the Company; (iii) to add any additional Events of Default; (iv) to provide for uncertificated Securities in addition to or in place of Certificated Securities;
(v) to change or eliminate any of the provisions of the Indenture; provided that any such change or elimination shall become effective only when there is no Security Outstanding of any series created prior to the execution of the amended
indenture which is entitled to the benefit of such provision; (vi) to secure the Securities; (vii) to establish the form or terms of Securities of any series and any related coupons; (viii) to evidence and provide for the acceptance
of appointment under the Indenture of a successor Trustee; (ix) to cure any ambiguity in the Indenture, to correct or supplement any provision in the Indenture which may be inconsistent with any other provision therein or to add any other
provisions with respect to matters or questions arising under the Indenture, provided that such actions shall not adversely affect the interests of the Holders in any material respect; or (x) to supplement any of the provisions of the Indenture
to such extent as shall be necessary to permit or facilitate the defeasance and discharge of any series of Securities, provided that such actions shall not adversely affect the interests of the Holder in any material respect. 
  

	 	11.	Defaults and Remedies. 

 If an
Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the Outstanding Securities, subject to certain limitations, may declare all the Securities to be immediately due and payable. Certain events
of bankruptcy or insolvency are Events of Default and shall result in the Securities being immediately due and payable upon the occurrence of such Events of Default without any further act of the Trustee or any Holder. 
 Holders of Securities may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may refuse to enforce
the Indenture or the Securities unless it receives reasonable indemnity or security. Subject to certain limitations, Holders of a majority in principal amount of the Outstanding Securities may direct the Trustee in its exercise of any trust or power
under the Indenture. The Holders of a majority in principal amount of the Outstanding Securities, by written notice to the Company and the Trustee, may rescind any declaration of acceleration and its consequences if the rescission would not conflict
with any judgment or decree, and if all Events of Default have been cured or waived except nonpayment of principal and interest that has become due solely because of the acceleration. 
  

	 	12.	Individual Rights of Trustee. 

 Subject to certain limitations imposed by the Trust Indenture Act, the Trustee or any Paying Agent or Registrar, in its individual or any other capacity, may become the owner or pledgee of Securities and may otherwise deal with the Company
or its Affiliates with the same rights it would have if it were not Trustee, Paying Agent or Registrar, as the case may be, under the Indenture. 
  

	 	13.	No Recourse Against Certain Others. 

 No director, officer, employee, incorporator or stockholder of the Company, as such, shall have any liability for any obligations of the Company under the Securities or the Indenture or for any claim based on, in respect of, or by reason
of, such obligations or their creation, solely

by reason of its status as a director, officer, employee, incorporator or stockholder of the Company. By accepting a Security, each Holder waives and releases all such liability (but only such
liability) as part of the consideration for issuance of such Security to such Holder.

and the Securities and coupons shall be governed by and construed in accordance with the law of the State of New York. The Indenture is subject to the provisions of the Trust Indenture Act that are required to be part of the Indenture and shall, to
