Execution Version 

AGREEMENT 
 This Agreement
is made and entered into as of February 4, 2021 (this “Agreement”) by and among ZIOPHARM Oncology, Inc. (the “Company”) and the entities and natural persons set forth in the signature pages hereto
(collectively, “WaterMill”) (each of the Company and WaterMill, a “Party” to this Agreement, and collectively, the “Parties”). 

RECITALS 
 WHEREAS, on
October 30, 2020, WaterMill filed a definitive consent statement (the “Consent Statement”) soliciting written consents from the stockholders of the Company (the “Consent Solicitation”) to vote in favor of
certain proposals, including the removal of four incumbent members of the Board of Directors of the Company (the “Board”) and the election of Robert W. Postma, Jaime Vieser and Holger Weis to fill the resulting vacancies; 

WHEREAS, on December 15, 2020, WaterMill delivered written consents from stockholders of the Company holding a majority of the
Company’s shares of common stock, par value $0.001 per share, outstanding and entitled to vote as of the record date of the Consent Solicitation of October 29, 2020 under Section 228 of the General Corporation Law of the State of
Delaware to remove Scott Tarriff from the Board and elect Jaime Vieser and Holger Weis to the Board as directors to fill the two vacancies created by the removal of Scott Tarriff and the previously reported resignation of Elan Z. Ezickson from the
Board effective December 3, 2020; 
 WHEREAS, the Company and WaterMill have subsequently engaged in various discussions and
communications concerning the Company’s business, financial performance and strategic plans; 
 WHEREAS, as of the date hereof, the
Company and WaterMill have determined to come to an agreement with respect to the composition of the Board and certain other matters, as provided in this Agreement; and 

WHEREAS, prior to the entry into this Agreement, the Company and the Board’s Corporate Governance and Nominating Committee (the
“Nominating Committee”) has reviewed the qualifications of and other relevant information regarding Mr. Postma in accordance with the Company’s organizational documents and internal policies and applicable law. 

NOW, THEREFORE, in consideration of the foregoing premises and the mutual covenants and agreements contained in this Agreement, and for other
good and valuable consideration, the receipt and sufficiency of which are acknowledged, the Parties, intending to be legally bound, agree as follows: 

1. Board Composition and Related Matters. 

(a) The Company agrees that, immediately following the execution of this Agreement, the Board and all applicable committees of the Board shall
take all necessary actions to (i) increase the size of the Board by one (1) director to a total of nine (9) directors and (ii) appoint Robert W. Postma as a member of the Board to fill the vacancy resulting from the increase in
the size of the Board, with a term expiring at the Company’s 2021 annual meeting of stockholders (including any adjournment, postponement, rescheduling or continuation thereof, the “2021 Annual Meeting”). 

 (b) During the Standstill Period (as defined below), the Company agrees that, provided that
such director is able and willing to serve on the Board, it will nominate each of Mr. Postma, Jamie Vieger and Holger Weis (each a “New Director” and collectively, the “New Directors”) for election at any
Stockholder Meeting at which directors are to be elected and will recommend, support and solicit proxies for the election of each New Director at such Stockholder Meeting in the same manner as it recommends, supports and solicits proxies (or
consents) for the election of the Company’s other director nominees. 
 (c) If any New Director (or any Replacement Director (as defined
below)) is unable or unwilling to serve as a director and ceases to be a director, resigns as a director, is removed as a director or for any other reason fails to serve or is not serving as a director at any time prior to the expiration of the
Standstill Period, WaterMill shall have the ability during the Standstill Period to recommend a person to be a replacement nominee to the Board in accordance with this Section 1(c) (any such replacement nominee, when
appointed to the Board, shall be referred to as a “Replacement Director”). Any Replacement Director must (i) be reasonably acceptable to the Board (such acceptance not to be unreasonably withheld), (ii) qualify as
“independent” pursuant to NASDAQ listing standards, and (iii) have the relevant financial and business experience to be a director of the Company. The Nominating Committee shall make its determination and recommendation regarding
whether such Replacement Director meets the foregoing criteria within five (5) Business Days after (A) such nominee has submitted to the Company the documentation required by Section 1(f) and
(B) representatives of the Board have conducted customary interview(s) of such nominee, if such interviews are requested by the Board or the Nominating Committee. The Company shall use its reasonable best efforts to conduct any interview(s)
contemplated by this Section 1(c) as promptly as practicable, but in any case, assuming reasonable availability of the nominee, within ten (10) Business Days after WaterMill’s submission of such nominee. In the
event the Nominating Committee does not accept a person recommended by WaterMill as the Replacement Director (such acceptance not to be unreasonably withheld), WaterMill shall have the right during the Standstill Period to recommend additional
substitute person(s) whose appointment shall be subject to the Nominating Committee recommending such person in accordance with the requirements and procedures described above. Upon the recommendation of a Replacement Director nominee by the
Nominating Committee, the Board shall vote on the appointment of such Replacement Director to the Board no later than five (5) Business Days after the Nominating Committee’s recommendation of such Replacement Director; provided,
however, that if the Board does not appoint such Replacement Director to the Board pursuant to this Section 1(c), the Parties shall continue to follow the procedures of this Section 1(c)
during the Standstill Period until a Replacement Director is elected to the Board. Upon a Replacement Director’s appointment to the Board, the Board and all applicable committees of the Board shall consider in good faith and promptly determine
whether to appoint such Replacement Director to any applicable committee of the Board of which the replaced director was a member immediately prior to such director’s resignation or removal, taking into account the skills and qualifications of
the Replacement Director and the other directors. Any Replacement Director designated pursuant to this Section 1(c) replacing a New Director prior to the mailing of the Company’s definitive proxy statement for any
Stockholder Meeting during the Standstill Period shall stand for election at such Stockholder Meeting together with the other director nominees. 

  
 -2- 

 (d) The Company agrees that the New Directors (or any Replacement Director) shall receive
(i) the same benefits of director and officer insurance as all other non-management directors on the Board, (ii) the same compensation for his or her service as a director as the compensation
received by all other independent directors on the Board, and (iii) such other benefits on the same basis as all other independent directors on the Board. 

(e) Each Party acknowledges that the New Directors (or any Replacement Director), upon appointment to the Board, shall be governed by, and each
New Director (or any Replacement Director) shall comply with, all of the same policies, processes, procedures, codes, rules, standards and guidelines applicable to all independent directors on the Board.

(f) WaterMill acknowledges that, prior to the date of this Agreement, Mr. Postma, and prior to any appointment, each Replacement Director,
is required to submit to the Company a fully completed copy of the Company’s standard director & officer questionnaire and other reasonable and customary director onboarding documentation applicable to directors of the Company. 

(g) During the Standstill Period, the Company (including the Board or any committee thereof) shall take no actions to (i) eliminate the
ability of stockholders to take action by written consent without a meeting of stockholders pursuant to Section 228 of the General Corporation Law of the State of Delaware (the “DGCL”), (ii) divide the directors into more than
one class of directors pursuant to Section 141(d) of the DGCL or (iii) modify any of the protections and obligations regarding confidentiality, conflicts of interest, fiduciary duties, trading and disclosure and other governance policies
applicable to the New Directors in any manner adverse to the New Directors and not generally applicable to all independent directors of the Company, in each case without the prior written consent of WaterMill. 

(h) WaterMill agrees that the Board or any committee thereof, in the exercise of its fiduciary duties, may recuse Mr. Postma (or any
Replacement Director serving on the Board in the place of Mr. Postma) from any portion of a Board or committee meeting at which the Board or any such committee is evaluating and/or taking action with respect to (i) the exercise of any of
the Company’s rights or enforcement of any of the obligations under this Agreement, (ii) any action taken in response to actions taken or proposed by WaterMill or its Affiliates with respect to the Company, or (iii) any proposed
transaction between the Company and WaterMill or any of its Affiliates. 
 (i) Other than as agreed to by the Company, WaterMill and each of
the New Directors agree that there shall be no contracts, plans or arrangements, written or otherwise, in effect during the term of this Agreement, between WaterMill and a New Director (or any Replacement Director) providing for any compensation,
reimbursement of expenses or indemnification of such New Director (or Replacement Director) in connection with or related to such New Director’s (or Replacement Director’s) service on the Board.

the right to vote, directly or indirectly, to be present in person or by proxy for quorum purposes and to be voted at any Stockholder Meeting or at any adjournments or postponements thereof, in accordance with the Board’s recommendations, as
such recommendations of the Board are set forth in the applicable definitive proxy or consent statement filed in respect thereof, with respect to the election, removal, and/or replacement of directors; provided, however, WaterMill
shall be permitted to vote in its sole discretion with respect to any publicly announced proposal not made in breach of this Agreement with respect to any matter other than the election, removal and/or replacement of directors.

securities of the Company; 
 (ii) form, join, maintain or in any way knowingly participate in any “group”
(within the meaning of Section 13(d)(3) of the Exchange Act) with respect to the shares of voting stock of the Company (other than a “group” that consists solely of all or some of the Affiliates of WaterMill); provided,
however, that nothing herein shall limit the ability of an Affiliate of WaterMill to join the “group” following the execution of this Agreement, so long as any such Affiliate agrees to be bound by the terms and conditions of
this Agreement; 
 (iii) deposit any shares of voting stock of the Company in any voting trust or subject any shares of
voting stock of the Company to any arrangement or agreement with respect to the voting of any shares of voting stock of the Company, other than any such voting trust, arrangement or agreement solely among the members of WaterMill and otherwise in
accordance with this Agreement; 
 (iv) seek or submit, or knowingly encourage any person or entity to seek or submit,
nomination(s) in furtherance of a “contested solicitation” for the appointment, election or removal of directors with respect to the Company or seek, or knowingly encourage or take any other action with respect to the appointment,

Company, (C) affirmatively solicit a third party to make an offer or proposal (with or without conditions) with respect to any merger, tender (or exchange) offer, acquisition, recapitalization, restructuring, disposition or other business
combination involving the Company, or publicly encourage, initiate or support any third party in making such an offer or proposal, (D) publicly comment on any third party proposal regarding any merger, tender (or exchange) offer, acquisition,

Company or any of its subsidiaries; 
 (x) acquire, seek or propose (publicly or otherwise) or agree to acquire, beneficial
ownership, directly or indirectly and acting alone or in concert, whether by purchase, tender or exchange offer, through the acquisition of control of another person, by joining a “group” within the meaning of Section 13(d)(3) of the
Exchange Act, a partnership, limited partnership, syndicate or other group, or through swap or hedging transactions or otherwise, any securities of the Company or any rights decoupled from the underlying securities of the Company that would result
in WaterMill (together with its Affiliates and Associates) owning, controlling or otherwise having any beneficial ownership interest in or aggregate economic exposure of more than 9.9% of the outstanding shares of voting stock of the Company; or

 (xi) enter into any discussions, negotiations, understandings or agreements (whether written or oral) with respect to any
action that WaterMill is prohibited from taking under this Section 2 or knowingly encourage any third person to take any action that WaterMill is prohibited from taking under this Section 2.

 (b) Except as expressly provided in this Agreement, WaterMill shall be entitled to
(i) vote any shares of voting stock of the Company that it beneficially owns as WaterMill determines in its sole discretion and (ii) disclose, publicly or otherwise, how it intends to vote or act with respect to any securities of the
Company, any stockholder proposal or other matter to be voted on by the stockholders of the Company and the reasons therefor. 
 (c)
Notwithstanding anything in Section 3(a) or elsewhere in this Agreement, nothing in this Agreement shall prohibit or restrict WaterMill from (i) communicating privately with the Board or any of the Company’s
officers regarding any matter, so long as such communications are not intended to, and would not reasonably be expected to, require any public disclosure of such communications, (ii) communicating with stockholders of the Company and others in
a manner that does not otherwise violate Section 3(a) or Section 6, or (iii) taking any action necessary to comply with any law, rule or regulation or any action required by any governmental

 (d) Nothing in Section 3 or

 6. Mutual Non-Disparagement.
Subject to applicable law, each of the Parties covenants and agrees that, for the duration of the Standstill Period or, if earlier, until such time as the other Party or any of its agents, subsidiaries, Affiliates, Associates, successors, assigns,
officers, key employees or directors shall have breached this Section 6, neither it nor any of its respective agents, subsidiaries, Affiliates, successors, assigns, officers, key employees or directors, shall in any way
publicly disparage, call into disrepute, or otherwise defame or slander the other Party or such other Party’s subsidiaries, Affiliates, Associates, successors, assigns, officers (including any current officer of a Party or a Party’s
subsidiaries who no longer serves in such capacity following the execution of this Agreement), or directors (including any current director of a Party or a Party’s subsidiaries who no longer serves in such capacity following the execution of
this Agreement), or any of their products or services, in any manner that would reasonably be expected to damage the business or reputation thereof. 

7. No Litigation. Each Party agrees that, from the date of this Agreement until the date that is fifteen
(15) calendar days after the date on which Mr. Postma (or any Replacement Director serving on the Board in the place of Mr. Postma) no longer serves on the Board, it shall not institute, solicit, join or assist in any lawsuit, claim
or proceeding before any court or government agency (each, a “Legal Proceeding”) against the other Party, any Affiliate of the other Party or any of their respective current or former directors or officers, except for (a) any
Legal Proceeding initiated primarily to remedy a breach of or to enforce this Agreement and (b) counterclaims with respect to any proceeding initiated by, or on behalf of one Party or its Affiliates against the other Party or its Affiliates;
provided, however, that the foregoing shall not prevent any Party or any of its Representatives from responding to oral questions, interrogatories, requests for information or documents, subpoenas, civil investigative demands or
similar processes (each, a “Legal Requirement”) in connection with any Legal Proceeding if such Legal Proceeding has not been initiated by, on behalf of or at the suggestion of such Party; provided, further, that in
the event any Party or any of its Representatives receives such Legal Requirement, such Party shall give prompt written notice of such Legal Requirement to the other Party (except where such notice would be legally prohibited or not practicable).
Each Party represents and warrants that neither it nor any assignee has filed any lawsuit against the other Party.

 8. Public Announcements. Promptly following the execution of this
Agreement, the Company shall issue a press release in the form set forth on Exhibit B (the “Press Release”) and file a Current Report on Form 8-K in the form previously agreed by the
Parties. Prior to the issuance of the Press Release and the Form 8-K, neither the Company (including the Board or any committee thereof) nor WaterMill nor any of their respective Affiliates or Associates shall
issue any press release or make any public announcement regarding this Agreement or the matters contemplated thereby without the prior written consent of the other Party. During the Standstill Period, no Party or any of its Affiliates shall make any

securities laws with respect to the purchase or sale of securities while in possession of material nonpublic information. 
 10.
Affiliates and Associates. WaterMill agrees to cause its Affiliates and Associates to comply with the terms of this Agreement and shall be responsible for any breaches of this Agreement by any such Affiliates or Associates. 

11. Specific Performance. Each of WaterMill, on the one hand, and the Company, on the other hand, acknowledges and agrees
that irreparable injury to the other Party to this Agreement would occur in the event any of the provisions of this Agreement are not performed in accordance with their specific terms or were otherwise breached and that such injury would not be
adequately compensable in monetary damages. It is accordingly agreed that WaterMill, on the one hand, and the Company, on the other hand (the “Moving Party”), shall each be entitled to specific enforcement of, and injunctive or
other equitable relief to prevent any violation of, the terms of this Agreement, and the other Party to this Agreement will not take action, directly or indirectly, in opposition to the Moving Party seeking such relief on the grounds that any other
remedy or relief is available at law or in equity, and irrevocably waives any requirement for the Moving Party to post any bond in connection with such action. This Section 11 is not the exclusive remedy for any violation
of this Agreement. 
 12. Expenses. The Company will reimburse WaterMill for its reasonable out-of-pocket fees and expenses (including legal expenses) incurred prior to the date of this Agreement in connection with the Consent Solicitation and the negotiation,
execution and effectuation of this Agreement and the transactions contemplated by this Agreement up to an amount of $400,000 in the aggregate.

agrees that it will not bring any action relating to this Agreement in any court other than the aforesaid courts. Each of the Parties to this Agreement irrevocably waives, and agrees not to assert in any action or proceeding with respect to this

17. Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent
jurisdiction to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions of this Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated. It is hereby

authorized representatives of each of the Parties. No failure or delay by either Party in exercising any right or remedy under this Agreement shall operate as a waiver of such right or remedy, nor shall any single or partial exercise or waiver of
any such right or remedy preclude any other or further exercise of any such right or remedy or the exercise of any other right or remedy. 

19. Successors and Assigns; No Third Party Beneficiaries. This Agreement shall bind the successors and permitted assigns
of the Parties, and inure to the benefit of any successor or permitted assign of any of the parties; provided, however, that no Party may assign this Agreement without, with respect to WaterMill, the prior written consent of the
Company, and with respect to the Company, the prior written consent of WaterMill. No provision of this Agreement is intended to confer any rights, benefits, remedies, obligations or liabilities hereunder upon any person other than the Parties to
this Agreement and their respective successors and assigns.

If Securities of a series are issuable as Bearer Securities, any request, demand, authorization, direction, notice, consent, waiver
or other action provided by this Indenture to be given or taken by Holders of Securities of such series may, alternatively, be
embodied in and evidenced by the record of Holders of Securities of such series voting in favor thereof, either in person or by
proxies duly appointed in writing, at any meeting of Holders of Securities of such series duly called and held in accordance with

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

signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient
proof of his authority. The fact and date of the execution of any such instrument or writing, or the authority of the Person executing
the same, may also be proved in any other reasonable manner which the Trustee deems sufficient.

 

(c) The
ownership of Registered Securities shall be proved by the Security Register. As to any matter relating to beneficial ownership
interests in any Global Security, the appropriate depository’s records shall be dispositive for purposes of this Indenture.

 

(d) The
ownership of Bearer Securities may be proved by the production of such Bearer Securities or by a certificate executed, as depository,
by any trust company, bank, banker or other depository, wherever situated, if such certificate shall be deemed by the Trustee to
be satisfactory, showing that at the date therein mentioned such Person had on deposit with such depository, or exhibited to it,
the Bearer Securities therein described; or such facts may be proved by the certificate or affidavit of the Person holding such
Bearer Securities, if such certificate or affidavit is deemed by the Trustee to be satisfactory. The Trustee and the Company may
assume that such ownership of any Bearer Security continues until (1) another certificate or affidavit bearing a later date issued
in respect of the same Bearer Security is produced, or (2) such Bearer Security is produced to the Trustee by some other Person,
or (3) such Bearer Security is surrendered in exchange for a Registered Security, or (4) such Bearer Security is no longer Outstanding.
The ownership of Bearer Securities may also be proved in any other manner which the Trustee deems sufficient.

 

(e) If
the Company shall solicit from the Holders of Registered Securities any request, demand, authorization, direction, notice, consent,
waiver or other Act, the Company may, at its option, in or pursuant to a Board Resolution, fix in advance a record date for the
determination of Holders entitled to give such request, demand, authorization, direction, notice, consent, waiver or other Act,

specified in or pursuant to such Board Resolution, which shall be a date not earlier than the date 30 days prior to the first solicitation
of Holders generally in connection therewith and not later than the date such solicitation is completed. If such a record date
is fixed, such request, demand, authorization, direction, notice, consent, waiver or other Act may be given before or after such
record date, but only the Holders of record at the close of business on such record date shall be deemed to be Holders for the
purposes of determining whether Holders of the requisite proportion of Outstanding Securities have authorized or agreed or consented
to such request, demand, authorization, direction, notice, consent, waiver or other Act, and for that purpose the Outstanding Securities
shall be computed as of such record date; provided that no such authorization, agreement or consent by the Holders on such record
date shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later than eleven
months after the record date.

 

(f) Any
request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Security shall bind every
future Holder of the same Security and the Holder of every Security issued upon the registration of transfer thereof or upon the
conversion 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

In any case where notice to Holders of Registered Securities is given by mail, neither the failure to mail such notice, nor any

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

publication to be not later than the latest date, if any, and not earlier than the earliest date, if any, prescribed for the giving
of such notice. Any such notice shall be deemed to have been given on the date of such publication or, if published more than once,
on the date of the first such publication.

 

If by reason of the
suspension of publication of any Authorized Newspaper or Authorized Newspapers or by reason of any other cause it shall be impracticable
to publish any notice to Holders of Bearer Securities as provided above, then such notification to Holders of Bearer Securities
as shall be given with the approval of the Trustee shall constitute sufficient notice to such Holders for every purpose hereunder.
Neither the failure to give notice by publication to any particular Holder of Bearer Securities as provided above, nor any defect
in any notice so published, shall affect the sufficiency of such notice with respect to other Holders of Bearer Securities or the
sufficiency of any notice to Holders of Registered Securities given as provided herein.

Any request, demand,
authorization, direction, notice, consent or waiver required or permitted under this Indenture shall be in the English language,

be a Business Day at any Place of Payment, then (notwithstanding any other provision of this Indenture or any Security or coupon
other than a provision in the Securities of any series which specifically states that such provision shall apply in lieu hereof),
payment of interest or principal (and premium or Make-Whole Amount, if any) or conversion or exchange of such Security need not
be made at such Place of Payment on such date, but (except as otherwise provided in the supplemental indenture with respect to
such Security) may be made on the next succeeding Business Day at such Place of Payment with the same force and effect as if made
on the Interest Payment Date, Redemption Date, Repayment Date or sinking fund payment date, or at the Stated Maturity or Maturity,
or on such last day for conversion or exchange, provided that no interest shall accrue on the amount so payable for the period
from and after such Interest Payment Date, Redemption Date, Repayment Date, sinking fund payment date, Stated Maturity or Maturity,
as the case may be.

Company, the Company’s assets or against any past, present or future stockholder, employee, officer, director or agent, as
such, of the Company or any successor, either directly or through the Company or any successor, under any rule of law, statute,
constitutional provision or by the enforcement of any assessment or penalty, or by any legal or equitable proceeding or otherwise,

based thereon or with respect thereto, it being expressly understood that the sole remedies hereunder or under any other document
with respect to the Securities against such parties with respect to such amounts, obligations or claims shall be against the Company

modified or excluded, the latter provision shall be deemed to apply to this Indenture as so modified or to be excluded, as the
case may be.

SECTION 203. Securities
Issuable in Global Form. If Securities of or within a series are issuable in the form of one or more Global Securities,
then, notwithstanding clause (9) of Section 301 and the provisions of Section 302, any such Global Security or Securities may provide
that it or they shall represent the aggregate amount of all Outstanding Securities of such series (or such lesser amount as is
permitted by the terms thereof) from time to time endorsed thereon and may also provide that the aggregate amount of Outstanding
Securities of such series represented thereby may from time to time be increased or decreased to reflect exchanges. Any endorsement
of any Global Security to reflect the amount, or any increase or decrease in the amount, or changes in the rights of Holders thereof,
of Outstanding Securities represented thereby shall be made (or caused to be made) by the Trustee in such manner or by such Person
or Persons as shall be specified therein or in the Company Order to be delivered to the Trustee pursuant to Section 303 or 304.
Subject to the provisions of Section 303 and, if applicable, Section 304, the Trustee shall deliver and redeliver any Global Security
in permanent global form in the manner and upon instructions given by the Person or Persons specified therein or in the applicable
Company Order. If a Company Order pursuant to Section 303 or 304 has been, or simultaneously is, delivered, any instructions by
the Company with respect to endorsement or delivery or redelivery of a Global Security shall be in writing but need not comply
with Section 102 and need not be accompanied by an Opinion of Counsel.

 

The provisions of the
last sentence of Section 303 shall apply to any Security represented by a Global Security if such Security was never issued and
sold by the Company and the Company delivers to the Trustee the Global Security together with written instructions (which need
not comply with Section 102 and need not be accompanied by an Opinion of Counsel) with regard to the reduction in the principal
amount of Securities represented thereby, together with the written statement contemplated by the last sentence of Section 303.

 

Notwithstanding the
provisions of Section 307, unless otherwise specified as contemplated by Section 301, payment of principal of and any premium or
Make-Whole Amount, if any, and interest on any Global Security in permanent global form shall be made to the registered Holder
thereof.

 

Notwithstanding the
provisions of Section 308 and except as provided in the preceding paragraph, the Company, the Trustee and any agent of the Company
and the Trustee shall treat as the Holder of such principal amount of Outstanding Securities represented by a permanent Global
Security (i) in the case of a permanent Global Security in registered form, the Holder of such permanent Global Security in registered
form, or (ii) in the case of a permanent Global Security in bearer form, Euroclear or Clearstream.

 

Any Global Security
authenticated and delivered hereunder shall bear a legend in substantially the following form:

 

“This Security
is a Global Security within the meaning set forth in the Indenture hereinafter referred to and is registered in the name of a Depository
or a nominee of a Depository. This Security is exchangeable for Securities registered in the name of a person other than the Depository
or its nominee only in the limited circumstances described in the Indenture, and may not be transferred except as a whole by the
Depository to a nominee of the Depository or by a nominee of the Depository to the Depository or another nominee of the Depository
or by the Depository or its nominee to a successor Depository or its nominee.”

relative to the reservation of such shares for purposes of conversion);

 

(23) If
the Securities of such series are to be issuable in definitive form (whether upon original issue or upon exchange of a temporary
Security of such series) only upon receipt of certain certificates or other documents or satisfaction of other conditions, then
the form and/or terms of such certificates, documents or conditions;

 

(24) Designation
of the Trustee, if different from the Trustee under the Indenture, with respect to such series and the terms applicable to such

    18

     

    

 

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 such Board Resolution
(subject to Section 303) and set forth in such Officers’ Certificate 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 302. 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 Securities of such series, other than Global Securities (which may be of any denomination), shall be issuable
in denominations of $1,000 and any integral multiple thereof or the equivalent amounts thereof in the case of Securities denominated
in the Foreign Currency or currency unit.

 

SECTION 303. Execution,
Authentication, Delivery and Dating. The Securities and any coupons appertaining thereto shall be executed on behalf of
the Company by its Chairman of the Board, its Chief Executive Officer, its President, or one of its Vice Presidents, 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 and 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 (accompanied by a copy of the Board Resolution and the Officers’ Certificate
or supplemental indenture contemplated by Section 301), and the Trustee in accordance with the Company Order shall authenticate
and deliver such Securities; provided, however, that, in connection with its original issuance, no Bearer Security shall be mailed
or otherwise delivered to any location in the United States; and provided further that, unless otherwise specified with respect
to any series of Securities pursuant to Section 301, a Bearer Security may be delivered in connection with its original issuance
only if the Person entitled to receive such Bearer Security shall have furnished a certificate to Euroclear or Clearstream, as
the case may be, in the form set forth in Exhibit B-1 to this Indenture or such other certificate as may be specified by the Company
with respect to any series of Securities pursuant to Section 301, dated no earlier than 15 days prior to the earlier of the date
on which such Bearer Security is delivered and the date on which any temporary Security first becomes exchangeable for such Bearer
Security in accordance with the terms of such temporary Security and this Indenture. If any Security shall be represented by a
permanent Global Security, then, for purposes of this Section and Section 304, 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 306, the Trustee shall not authenticate and deliver any Bearer Security unless all appurtenant coupons
for interest then matured have been detached and canceled.

 

If all 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 or formula, 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 that

 

    19

     

    

 

(a) the
form or forms of such Securities and any coupons have been established in conformity with the provisions of this Indenture;

 

(b) the
terms of such Securities and any coupons have been established in conformity with the provisions of this Indenture; and

 

(c) 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 legally binding obligations of the Company, enforceable in accordance with their terms,
subject to applicable bankruptcy, insolvency, fraudulent transfer, reorganization and other similar laws of general applicability
relating to or affecting the enforcement of creditors’ rights generally and to general equitable principles; and

 

(ii) an Officers’
Certificate stating that all conditions precedent provided for in this Indenture relating to the issuance of the Securities have
been complied with and that, to the best of 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.

 

If such form or terms
have been so established, the Trustee shall not be required to authenticate such Securities (or to enter into the related supplemental
indenture, if applicable) 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
provisions of Section 301 and of the preceding paragraph, if all the Securities of any series are not to be issued at one time,
it shall not be necessary to deliver an Officers’ Certificate otherwise required pursuant to Section 301 or a Company Order,
or an Opinion of Counsel or an Officers’ Certificate otherwise required pursuant to the preceding paragraph at the time of
issuance of each Security of such series, but such order, opinion and 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.

 

Each Registered Security
shall be dated the date of its authentication and each Bearer Security shall be dated as of the date specified as contemplated
by Section 301.

 

No Security or coupon
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 (subject to Section 611) 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 (including a Global Security)
shall have been authenticated and delivered hereunder but never issued and sold by the Company, and the Company shall deliver such
Security to the Trustee for cancellation as provided in Section 309 together with a written statement (which need not comply with
Section 102 and need not be accompanied by an Opinion of Counsel) stating that such Security has never been issued 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.

 

    20

     

    

 

SECTION 304. Temporary
Securities.

 

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

 

Except in the case
of temporary Global Securities (which shall be exchanged as otherwise provided herein or as otherwise provided in or pursuant to
a Board Resolution or supplemental indenture pursuant to Section 301), 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 (in accordance with a Company Order delivered at or
prior to the authentication of the first definitive security to such series) and the Trustee shall authenticate and deliver in
exchange therefor a like principal amount of definitive Securities of the same series of authorized denominations; provided, however,
that no definitive Bearer Security shall be delivered in exchange for a temporary Registered Security; and provided further that
a definitive Bearer Security shall be delivered in exchange for a temporary Bearer Security only in compliance with the conditions
set forth in Section 305. 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 or supplemental indenture pursuant to Section 301, the following provisions
of this Section 304(b) shall govern the exchange of temporary Securities other than through the facilities of the DTC. If any such
temporary Security is issued in global form, then such temporary Global Security shall, unless otherwise provided therein, be delivered
to the London office of a depository or common depository upon and pursuant to written direction of the Company (the “Common
Depository”), 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 Depository to the Trustee, as the Company’s agent for such
purpose, to be exchanged, in whole or from time to time in part, for definitive Securities without charge, and the Trustee shall
authenticate and deliver, in exchange for each portion of such temporary Global Security, an equal aggregate principal amount of
definitive Securities of the same series of authorized denominations and of like tenor as the portion of such temporary Global
Security to be exchanged. The definitive Securities to be delivered in exchange for any such temporary Global Security shall be
in bearer form, registered form, permanent global bearer form or permanent global registered form, or any combination thereof,
as specified as contemplated by Section 301, and, if any combination thereof is so specified, as requested by the beneficial owner
thereof (as directed by or pursuant to information provided by the Common Depository); provided, however, that, unless otherwise
specified in such temporary Global Security, upon such presentation by the Common Depository, such temporary Global Security shall
be 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 form set forth in Exhibit B-2 to this Indenture or in such other form as may be established pursuant to Section 301; and provided
further that definitive Bearer Securities shall be delivered in exchange for a portion of a temporary Global Security only in compliance
with the requirements of Section 303.

 

    21

     

    

 

Unless otherwise specified
in such temporary Global Security, the interest of a beneficial owner of Securities of a series in a temporary Global Security
shall be exchanged for definitive Securities of the same series and of like tenor following the Exchange Date when the account
holder instructs Euroclear or Clearstream, as the case may be, to request such exchange on his behalf and delivers to Euroclear
or Clearstream, as the case may be, a certificate in the form set forth in Exhibit B-1 to this Indenture (or in such other form
as may be established pursuant to Section 301), dated no earlier than 15 days prior to the Exchange Date, copies of which certificate
shall be available from the offices of Euroclear 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 to an address located outside the United States.

 

Until exchanged in
full as hereinabove provided, the temporary Securities of any series shall in all respects be entitled to the same benefits under
this Indenture as definitive Securities of the same series and of like tenor authenticated and delivered hereunder, except that,
unless otherwise specified as contemplated by Section 301, interest payable on a temporary Global Security on an Interest Payment
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 of a certificate or certificates in the
form set forth in Exhibit B-2 to this Indenture (or in such other forms as may be established pursuant to Section 301), for credit
without further interest on or after such Interest Payment Date to the respective accounts of Persons who are the beneficial owners
of such temporary Global Security on such Interest Payment Date and who have each delivered to Euroclear or Clearstream, as the
case may be, a certificate dated no earlier than 15 days prior to the Interest Payment Date occurring prior to such Exchange Date
in the form set forth as Exhibit B-1 to this Indenture (or in such other forms as may be established pursuant to Section 301).
Notwithstanding anything to the contrary herein contained, the certifications made pursuant to this paragraph shall satisfy the
certification requirements of the preceding two paragraphs of this Section 304(b) and of the third paragraph of Section 303 of
this Indenture and the interests of the Persons who are the beneficial owners of the temporary Global Security with respect to
which such certification was made will be exchanged for definitive Securities of the same series and of like tenor on the Exchange
Date or the date of certification if such date occurs after the Exchange Date, without further act or deed by such beneficial owners.
Except as otherwise provided in this paragraph, no payments of principal or interest owing with respect to a beneficial interest
in a temporary Global Security will be made unless and until such interest in such temporary Global Security shall have been exchanged
for an interest in a definitive Security. Any interest so received by Euroclear and Clearstream and not paid as herein provided
shall be returned to the Trustee prior to the expiration of two years after such Interest Payment Date in order to be repaid to
the Company.

 

    22

     

    

 

With respect to Exhibit
B-1 or B-2 to this Indenture, the Company may, in its discretion and if required or desirable under applicable law, substitute
one or more other forms of such exhibits for such exhibits, eliminate the requirement that any or all certificate be provided,
or change the time that any certificate may be required, provided that such substitute form or forms or notice of elimination or
change of such certification requirement have theretofore been delivered to the Trustee with a Company Request and such form or
forms, elimination or change is reasonably acceptable to the Trustee.

 

SECTION 305. Registration,
Registration of Transfer, Conversion 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. In the event that the Trustee shall
cease to be Security Registrar, it shall have the right to examine, and be provided a copy of, the Security Register at all reasonable
times.

 

Subject to the provisions
of this Section 305, upon surrender for registration of transfer of any Registered Security of any series at any office or agency
of the Company in a Place of Payment for that series, the Company shall execute, and the Trustee shall authenticate and deliver,
in the name of the designated transferee or transferees, one or more new Registered Securities of the same series, of any authorized
denominations and of a like aggregate principal amount, bearing a number not contemporaneously outstanding, and containing identical
terms and provisions.

 

Subject to the provisions
of this Section 305, at the option of the Holder, Registered Securities of any series may be exchanged for other Registered Securities
of the same series, of any authorized denomination or denominations and of a like aggregate principal amount, containing identical
terms and provisions, upon surrender of the Registered Securities to be exchanged at any such office or agency. Whenever any such
Registered Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver,
the Registered Securities which the Holder making the exchange is entitled to receive. Unless otherwise specified with respect
to any series of Securities as contemplated by Section 301, Bearer Securities may not be issued in exchange for Registered Securities.

 

    23

     

    

 

If (but only if) permitted
by the applicable Board Resolution and (subject to Section 303) set forth in the applicable Officers’ Certificate, or in
any indenture supplemental hereto, delivered as contemplated by Section 301, at the option of the Holder, Bearer Securities of
any series may be exchanged for Registered Securities of the same series of any authorized denominations and of a like aggregate
principal amount and tenor, upon surrender of the Bearer Securities to be exchanged at any such office or agency, with all unmatured
coupons and all matured coupons in default thereto appertaining. If the Holder of a Bearer Security is unable to produce any such
unmatured coupon or coupons or matured coupon or coupons in default, any such permitted exchange may be effected if the Bearer
Securities are accompanied by payment in funds acceptable to the Company (or to the Trustee for the Security in case of matured
coupons in default) in an amount equal to the face amount of such missing coupon or coupons, or the surrender of such missing coupon
or coupons may be waived by the Company and the Trustee if there is furnished to them such security or indemnity as they may require
to save each of them and any Paying Agent harmless. If thereafter the Holder of such Security shall surrender to any Paying Agent
any such missing coupon in respect of which such a payment shall have been made, such Holder shall be entitled to receive the amount
of such payment; provided, however, that, except as otherwise provided in Section 1002, interest represented by coupons shall be
payable only upon presentation and surrender of those coupons at an office or agency located outside the United States. Notwithstanding
the foregoing, in case a Bearer Security of any series is surrendered at any such office or agency in a permitted exchange for
a Registered Security of the same series and like tenor after the close of business at such office or agency on (i) any Regular
Record Date and before the opening of business at such office or agency on the relevant Interest Payment Date, or (ii) any Special
Record Date and before the opening of business at such office or agency on the related proposed date for payment of Defaulted Interest,
such Bearer Security shall be surrendered without the coupon relating to such Interest Payment Date or proposed date for payment,
as the case may be, and interest or Defaulted Interest, as the case may be, will not be payable on such Interest Payment Date or
proposed date for payment, as the case may be, in respect of the Registered Security issued in exchange for such Bearer Security,
but will be payable only to the Holder of such coupon when due in accordance with the provisions of this Indenture. Whenever any
Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Securities
which the Holder making the exchange is entitled to receive.

 

Notwithstanding the
foregoing, except as otherwise specified as contemplated by Section 301, any permanent Global Security shall be exchangeable only
as provided in this paragraph. If the depository for any permanent Global Security is DTC, then, unless the terms of such Global
Security expressly permit such Global Security to be exchanged in whole or in part for definitive Securities, a Global Security
may be transferred, in whole but not in part, only to a nominee of DTC, or by a nominee of DTC to DTC, or to a successor to DTC
for such Global Security selected or approved by the Company or to a nominee of such successor to DTC. If at any time DTC notifies
the Company that it is unwilling or unable to continue as depository for the applicable Global Security or Securities or if at
any time DTC ceases to be a clearing agency registered under the Exchange Act if so required by applicable law or regulation, the
Company shall appoint a successor depository with respect to such Global Security or Securities. If (w) a successor depository
for such Global Security or Securities is not appointed by the Company within 90 days after the Company receives such notice or
becomes aware of such unwillingness, inability or ineligibility, (x) the Company delivers to the Trustee for Securities of such
series in registered form a Company Order stating that the Securities of such series shall be exchangeable, (y) an Event of Default
has occurred and is continuing and the beneficial owners representing a majority in principal amount of the applicable series of
Securities represented by such Global Security or Securities advise DTC to cease acting as depository for such Global Security
or Securities or (z) the Company, in its sole discretion, determines at any time that all Outstanding Securities (but not less
than all) of any series issued or issuable in the form of one or more Global Securities shall no longer be represented by such
Global Security or Securities, then the Company shall execute, and the Trustee shall authenticate and deliver definitive Securities
of like series, rank, tenor and terms in definitive form in an aggregate principal amount equal to the principal amount of such
Global Security or Securities. If any beneficial owner of an interest in a permanent global Security is otherwise 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 301 and provided that any applicable notice provided in the permanent Global Security shall
have been given, then without unnecessary delay but in any event not later than the earliest date on which such interest may be
so exchanged, the Company shall execute, and the Trustee shall authenticate and deliver definitive Securities in aggregate principal
amount equal to the principal amount of such beneficial owner’s interest in such permanent Global Security. On or after the
earliest date on which such interests may be so exchanged, such permanent Global Security shall be surrendered for exchange by
DTC or such other depository as shall be specified in the Company Order with respect thereto to the Trustee, as the Company’s
agent for such purpose; provided, however, that no such exchanges may occur during a period beginning at the opening of business
15 days before any selection of Securities to be redeemed and ending on the relevant Redemption Date if the Security for which
exchange is requested may be among those selected for redemption; and provided further that no Bearer Security delivered in exchange
for a portion of a permanent Global Security shall be mailed or otherwise delivered to any location in the United States. If a
Registered Security is issued in exchange for any portion of a permanent Global Security after the close of business at the office
or agency where such exchange occurs on (i) any Regular Record Date and before the opening of business at such office or agency
on the relevant Interest Payment Date, or (ii) any Special Record Date and 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.

 

    24

     

    

 

All Securities issued
upon any registration of transfer or conversion or exchange of Securities shall be the valid obligations of the Company, evidencing
the same debt, and entitled to the same benefits under this Indenture, as the Securities surrendered upon such registration of
transfer or conversion or exchange.

 

Every Registered Security
presented or surrendered for registration of transfer or for conversion, exchange or redemption shall (if so required by the Company
or the Security Registrar) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the
Company and the Security Registrar, duly executed by the Holder thereof or his attorney duly authorized in writing.

 

No service charge shall
be made to the Holder for any registration of transfer or conversion or exchange of Securities, but the Company may require payment
of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer
or conversion or exchange of Securities, other than exchanges pursuant to Section 304, 906, 1107, 1305 or 1604 not involving any
transfer.

 

The Company or the
Trustee, as applicable, shall not be required (i) to issue, register the transfer of or exchange any Security if such Security
may be among those selected for redemption during a period beginning at the opening of business 15 days before selection of the
Securities to be redeemed under Section 1103 and ending at the close of business on (A) if such Securities are issuable only as
Registered Securities, the day of the mailing of the relevant notice of redemption and (B) if such Securities are issuable as Bearer
Securities, the day of the first publication of the relevant notice of redemption or, if such Securities are also issuable as Registered
Securities and there is no publication, the mailing of the relevant notice of redemption, or (ii) to register the transfer of or
exchange any Registered Security so selected for redemption in whole or in part, except, in the case of any Registered Security
to be redeemed in part, the portion thereof not to be redeemed, or (iii) to exchange any Bearer Security so selected for redemption
except that such a Bearer Security may be exchanged for a Registered Security of that series and like tenor, provided that such
Registered Security shall be simultaneously surrendered for 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.

 

Furthermore, notwithstanding
any other provision of this Section 305, the Company will not be required to exchange any Securities if, as a result of the exchange,
the Company would suffer adverse consequences under any United States law or regulation.

 

SECTION 306. Mutilated,
Destroyed, Lost and Stolen Securities. If any mutilated Security or a Security with a mutilated coupon appertaining to
it is surrendered to the Trustee or the Company, together with, 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.

 

    25

     

    

 

If there shall be delivered
to the Company and to the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security or coupon,
and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then,
in the absence of notice to the Company or the Trustee that such Security or coupon has been acquired by a bona fide purchaser,
the Company shall execute and upon 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 destroyed, lost or stolen Security or to the Security to which such destroyed, lost
or stolen coupon appertains, pay such Security or coupon if the applicant for such payment shall furnish to the Company and the
Trustee for such Security such security or indemnity as may be required by them to save each of them harmless, and in the case
of destruction, loss or theft, evidence satisfactory to the Company and Trustee and any agent of any of them of the destruction,
loss or theft of such Security and the ownership thereof; provided, however, that payment of principal of (and premium or Make-Whole
Amount, if any), and interest, if any, on, Bearer Securities shall, except as otherwise provided in Section 1002, be payable only
at an office or agency located outside the United States and, unless otherwise specified as contemplated by Section 301, any interest
on Bearer Securities shall be payable only upon presentation and surrender of the coupons appertaining thereto.

 

Upon the issuance of
any new Security under this Section, the Company may require the payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected
therewith.

 

Every new Security
of any series with its coupons, if any, issued pursuant to this Section in lieu of any destroyed, lost or stolen Security, or in
exchange for a Security to which a destroyed, lost or stolen coupon appertains, shall constitute an original additional contractual
obligation of the Company, whether or not the destroyed, lost or stolen Security and its coupons, if any, or the destroyed, lost
or stolen coupon shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally
and proportionately with any and all other Securities of that series and their coupons, if any, duly issued hereunder.

 

The provisions of this
Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities or coupons.

 

    26

     

    

 

SECTION 307. Payment
of Interest; Interest Rights Preserved. Except as otherwise specified with respect to a series of Securities in accordance
with the provisions of Section 301, interest on any Registered Security that is payable, and is punctually paid or duly provided
for, on any Interest Payment Date shall be paid to the Person in whose name that Security (or one or more Predecessor Securities)
is registered at the close of business on the Regular Record Date for such interest payment at the office or agency of the Company
maintained for such purpose pursuant to Section 1002; provided, however, that each installment of interest on any Registered Security
may at the Company’s option be paid by (i) mailing a check for such interest, payable to or upon the written order of the
Person entitled thereto pursuant to Section 308, to the address of such Person as it appears on the Security Register or (ii) transfer
to an account maintained by the payee located inside the United States.

 

Unless otherwise provided
as contemplated by Section 301 with respect to the Securities of any series, payment of interest may be made, in the case of a
Bearer Security, by transfer to an account maintained by the payee with a bank located outside the United States.

 

Unless otherwise provided
as contemplated by Section 301, every permanent Global Security will provide that interest, if any, payable on any Interest Payment
Date will be paid to DTC, Euroclear and/or Clearstream, as the case may be, with respect to that portion of such permanent Global
Security held for its account by Cede & Co. or the Common Depository, as the case may be, for the purpose of permitting such
party to credit the interest received by it in respect of such permanent Global Security to the accounts of the beneficial owners
thereof.

 

In case a Bearer Security
of any series is surrendered in exchange for a Registered Security of such series after the close of business (at an office or
agency in a Place of Payment for such series) on any Regular Record Date and before the opening of business (at such office or
agency) on the next succeeding Interest Payment Date, such Bearer Security shall be surrendered without the coupon relating to
such Interest Payment Date and interest will not be payable on such Interest Payment Date in respect of the Registered Security
issued in exchange for such Bearer Security, but will be payable only to the Holder of such coupon when due in accordance with
the provisions of this Indenture.

 

Except as otherwise
specified with respect to a series of Securities in accordance with the provisions of Section 301, any interest on any Registered
Security of any series that is payable, but is not punctually paid or duly provided for, on any Interest Payment Date (herein called
”Defaulted Interest”) shall forthwith cease to be payable to the registered Holder thereof on the relevant Regular
Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company, at its election in each
case, as provided in clause (1) or (2) below:

 

(1) The
Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Registered Securities of such series
(or their respective Predecessor Securities) are registered at the close of business on a Special Record Date for the payment of
such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount
of Defaulted Interest proposed to be paid on each Registered Security of such series and the date of the proposed payment (which
shall not be less than 20 days after such notice is received by the Trustee), and at the same time the Company shall deposit with
the Trustee an amount of money in the currency or currencies, currency unit or units or composite currency or currencies in which
the Securities of such series are payable (except as otherwise specified pursuant to Section 301 for the Securities of such series)
equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory
to the Trustee for such deposit on or prior to the date of the proposed payment, such money when deposited to be held in trust
for the benefit of the Persons entitled to such Defaulted Interest as in this clause provided. Thereupon the Trustee shall fix
a Special 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. The Trustee may, in its discretion, in the name and at the expense of the
Company, cause a similar notice to be published at least once in an Authorized Newspaper in each Place of Payment, but such publications
shall not be a condition precedent to the establishment of such Special Record Date. Notice of the proposed payment of such Defaulted
Interest and the Special Record Date therefor having been mailed as aforesaid, such Defaulted Interest shall be paid to the Persons
in whose names the 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.

 

    27

     

    

 

(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 over-the-counter market or securities exchange on which such Securities may be quoted or listed, and
upon such notice as may be required by such market or exchange, if, after notice given by the Company to the Trustee of the proposed
payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee.

 

Subject to the foregoing
provisions of this Section and Section 305, each Security delivered under this Indenture upon registration of transfer of or upon
conversion 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 308. Persons
Deemed Owners. Prior to due presentment of a Registered Security for registration of transfer, the Company, the Trustee
and any agent of the Company or the Trustee may treat the Person in whose name such Registered Security is registered as the owner
of such Security for the purpose of receiving payment of principal of (and premium or Make-Whole Amount, if any), and (subject
to Sections 305 and 307) interest on, 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. All such payments so made to any such Person, or upon such Person’s order, shall be valid, and, to the extent
of the sum or sums so paid, effectual to satisfy and discharge the liability for money payable upon any such Security.

 

Title to any Bearer
Security and any coupons appertaining thereto shall pass by delivery. The Company, the Trustee and any agent of the Company or
the Trustee may treat the Holder of any Bearer Security and the Holder of any coupon as the absolute owner of such Security or
coupon for the purpose of receiving payment thereof or on account thereof and for all other purposes whatsoever, whether or not
such Security or coupon be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected
by notice to the contrary.

 

No holder of any beneficial
interest in any Global Security held on its behalf by a depository shall have any rights under this Indenture with respect to such
Global Security and such depository (which is the Holder of such security) shall be treated by the Company, the Trustee, and any
agent of the Company or the Trustee as the owner of such Global Security for all purposes whatsoever. 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 Global Security or for maintaining, supervising or reviewing
any records relating to such beneficial ownership interests.

 

    28

     

    

 

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

 

SECTION 309. Cancellation.
All Securities and coupons surrendered for payment, redemption, repayment at the option of the Holder, registration of transfer
or conversion 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, upon direction by the Company, shall be promptly cancelled by it. The Company may at any time deliver to
the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired
in any manner whatsoever, and may deliver to the Trustee (or to any other Person for delivery to the Trustee) for cancellation
any Securities previously authenticated hereunder which the Company has 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 disposed of by the Trustee in accordance with its customary practices (subject to the record retention requirements of
the Exchange Act).

 

SECTION 310. Computation
of Interest. Except as otherwise specified as contemplated by Section 301 with respect to Securities of any series, interest
on the Securities of each series shall be computed on the basis of a 360-day year consisting of twelve 30-day months.

 

SECTION 311. CUSIP
Numbers. The Company in issuing the Securities may use “CUSIP” numbers (if then generally in use), and, if
so, the Trustee shall use “CUSIP” numbers in notices of redemption as a convenience to Holders; provided, however,
that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities
or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed
on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company will
promptly notify the Trustee of any change in the “CUSIP” numbers.

 

ARTICLE
4.

series of Securities specified in such Company Request (except as to any surviving rights of registration of transfer or conversion
or exchange of Securities of such series herein expressly provided for), and the Trustee, upon receipt of a Company Order, and
at the expense of the Company, shall execute instruments in form and substance satisfactory to the Trustee and the Company acknowledging
satisfaction and discharge of this Indenture as to such series when

 

(1) either

Securities of such series theretofore authenticated and delivered and all coupons, if any, appertaining thereto (other than (i)
coupons appertaining to Bearer Securities surrendered for exchange for Registered Securities and maturing after such exchange,

have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 306, (iii) coupons appertaining

in Section 1003) have been delivered to the Trustee for cancellation; or

 

    29

     

    

 

(B) all
Securities of such series and, in the case of (i) or (ii) below, any coupons appertaining thereto not theretofore delivered to
the Trustee for cancellation

become due and payable, or

 

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

 

(iii) if
redeemable at the option of the Company, are to be called for redemption within one year under arrangements satisfactory to the
Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company,

 

and the Company, in the case of (i), (ii)
or (iii) above, has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust for the purpose an
amount in the currency or currencies, currency unit or units or composite currency or currencies in which the Securities of such
series are payable, sufficient to pay and discharge the entire indebtedness on such Securities and such coupons not theretofore
delivered to the Trustee for cancellation, for principal (and premium or Make-Whole Amount, if any) and interest to the date of
such deposit (in the case of Securities which have become due and payable) or to the Stated Maturity or Redemption Date, as the
case may be;

 

(2) the
Company has paid or caused to be paid all other sums payable hereunder by the Company; and

 

(3) the
Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions

with.

 

Notwithstanding the
satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee and any predecessor Trustee under Section
606, the obligations of the Company to any Authenticating Agent under Section 611 and, if money shall have been deposited with
and held by the Trustee pursuant to subclause (B) of clause (1) of this Section, the obligations of the Trustee under Section 402
and the last paragraph of Section 1003 shall survive such satisfaction and discharge.

 

SECTION 402. Application
of Trust Funds. Subject to the provisions of the last paragraph of Section 1003, all money deposited with the Trustee pursuant
to Section 401 shall be held in trust and applied by it, in accordance with the provisions of the Securities, the coupons and this
Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as
the Trustee may determine, to the Persons entitled thereto, of the principal (and premium or Make-Whole Amount, if any), and any
interest for whose payment such money has been deposited with or received by the Trustee, but such money need not be segregated
from other funds except to the extent required by law.

REMEDIES

 

SECTION 501. Events
of Default. “Event of Default,” wherever used herein with respect to any particular series of Securities, means
any one of the following events (whatever the reason for such Event of Default and whether or not it shall be voluntary or involuntary
or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of
any administrative or governmental body):

 

(1) default
in the payment of any interest on any Security of that series or of any coupon appertaining thereto, when such interest or coupon
becomes due and payable, and continuance of such default for a period of 30 days; or

 

(2) default
in the payment of the principal of (or premium or Make-Whole Amount, if any, on) any Security of that series when it becomes due
and payable at its Maturity; or

 

(3) default
in the deposit of any sinking fund payment, to the extent applicable to such series of Securities, when and as due by the terms
of any Security of that series; or

 

(4) default
in the performance, or breach, of any covenant or warranty of the Company in this Indenture with respect to any Security of that
series (other than a covenant or warranty a default in whose performance or whose breach is elsewhere in this Section specifically
dealt with or which has expressly been included in this Indenture solely for the benefit of a series of Securities other than that
series), and continuance of such default or breach for a period of 60 days after there has been given, by registered or certified
mail, to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in principal amount of the
Outstanding Securities of that series a written notice specifying such default or breach and requiring it to be remedied and stating
that such notice is a “Notice of Default” hereunder; or

 

(5) default
under any bond, debenture, note, mortgage, indenture or instrument under which there may be issued or by which there may be secured
or evidenced any indebtedness for money borrowed by the Company (or by any Subsidiary, the repayment of which the Company has guaranteed
or for which the Company is directly responsible or liable as obligor or guarantor), having an aggregate principal amount outstanding
of at least $30,000,000, whether such indebtedness now exists or shall hereafter be created, which default shall have resulted
in such indebtedness becoming or being declared due and payable prior to the date on which it would otherwise have become due and
payable, without such indebtedness having been discharged, or such acceleration having been rescinded or annulled, within a period
of 30 days after there shall have been given, by registered or certified mail, to the Company by the Trustee or to the Company
and the Trustee by the Holders of at least 10% in principal amount of the Outstanding Securities of that series a written notice
specifying such default and requiring the Company to cause such indebtedness to be discharged or cause such acceleration to be
rescinded or annulled and stating that such notice is a “Notice of Default” hereunder; provided, however, that, subject
to the provisions of Sections 601 and 602, the Trustee shall not be deemed to have knowledge of such default unless either (A)
a Responsible Officer of the Trustee shall have knowledge of such default or (B) the Trustee shall have received written notice
thereof from the Company, from any Holder, from the holder of any such indebtedness or from the trustee under any such mortgage,
indenture or other instrument; or

 

    31

     

    

 

(6) the
Company or any Significant Subsidiary pursuant to or within the meaning of any Bankruptcy Law:

 

(A) commences
a voluntary case,

 

(B) consents
to the entry of an order for relief against it in an involuntary case,

 

(C) consents
to the appointment of a Custodian of it or for all or substantially all of its property, or

 

(D) makes
a general assignment for the benefit of its creditors; or

 

(7) a
court of competent jurisdiction enters an order or decree under any Bankruptcy Law that:

 

(A) is
for relief against the Company or any Significant Subsidiary in an involuntary case,

 

(B) appoints
a Custodian of the Company or any Significant Subsidiary or for all or substantially all of either of its property, or

 

(C) orders
the liquidation of the Company or any Significant Subsidiary, and the order or decree remains unstayed and in effect for 90 days;
or

 

(8) any
other Event of Default provided with respect to Securities of that series.

 

As used in this Section
501, the term “Bankruptcy Law” means title 11, U.S. Code or any similar Federal or state law for the relief of debtors
and the term “Custodian” means any receiver, trustee, assignee, liquidator or other similar official under any Bankruptcy
Law.

 

SECTION 502. Acceleration
of Maturity; Rescission and Annulment. If an Event of Default with respect to Securities of any series at the time Outstanding
occurs and is continuing, then and in every such case the Trustee or the Holders of not less than 25% in principal amount of the
Outstanding Securities of that series may declare the principal amount (or, if Securities of that Series 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 in this Article provided, the Holders of a majority in principal
amount of the Outstanding Securities of that series, by written notice to the Company and the Trustee, may rescind and annul such
declaration of acceleration and its consequences if:

 

(1) the
Company has paid or deposited with the Trustee a sum sufficient to pay in the currency, currency unit or composite currency in
which the Securities of such series are payable (except as otherwise specified pursuant to Section 301 for the Securities of such
series):

 

(A) all
overdue installments of interest on all Outstanding Securities of that series and any related coupons,

 

(B) the
principal of (and premium or Make-Whole Amount, if any, on) any Outstanding Securities of that series which have become due otherwise
than by such declaration of acceleration and interest thereon at the rate or rates borne by or provided for in such Securities,

 

    32

     

    

 

(C) to
the extent that payment of such interest is lawful, interest upon overdue installments of interest at the rate or rates borne by
or provided for in such Securities, and

 

(D) all
sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel; and

 

(2) all
Events of Default with respect to Securities of that series, other than the nonpayment of the principal of (or premium or Make-Whole
Amount, if any) or interest on Securities of that series which have become due solely by such declaration of acceleration, have
been cured or waived as provided in Section 513.

 

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

 

SECTION 503. Collection
of Indebtedness and Suits for Enforcement by Trustee. The Company covenants that if:

 

(1) default
is made in the payment of any installment of interest 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 or Make-Whole Amount, if any, on) any Security of any series at its Maturity,

 

then the Company will, upon demand of the
Trustee, pay to the Trustee, for the benefit of the Holders of such Securities of such series and coupons, the whole amount then
due and payable on such Securities and coupons for principal (and premium or Make-Whole Amount, if any) and interest, with interest
upon any overdue principal (and premium or Make-Whole Amount, if any) and, to the extent that payment of such interest shall be
legally enforceable, upon any overdue installments of interest at the rate or rates borne by or provided for in such Securities,
and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the
reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

 

If the Company fails
to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute
a judicial proceeding for the collection of the sums so due and unpaid, and may prosecute such proceeding to judgment or final
decree, and may enforce the same against the Company or any other obligor upon such Securities of such series and collect the moneys
adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon such
Securities of such series, wherever situated.

 

If an Event of Default
with respect to Securities of any series occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce
its rights and the rights of the Holders of Securities of such series and any related coupons by such appropriate judicial proceedings
as the Trustee shall deem necessary to protect and enforce any such rights, whether for the specific enforcement of any covenant
or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy.

 

    33

     

    

 

SECTION 504. Trustee
May File Proofs of Claim. In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization,
arrangement, adjustment, composition or other judicial proceeding relative to the Company or any other obligor upon the Securities
or the property of the Company or of such other obligor or their creditors, the Trustee (irrespective of whether the principal
of the Securities of any series shall then be due and payable as therein expressed or by declaration or otherwise and irrespective
of whether the Trustee shall have made any demand on the Company for the payment of overdue principal, premium or Make-Whole Amount,
if any, or interest) shall be entitled and empowered, by intervention in such proceeding or otherwise:

 

(i) to
file and prove a claim for the whole amount, or such lesser amount as may be provided for in the Securities of such series, of
principal (and premium or Make-Whole Amount, if any) and interest owing and unpaid in respect of the Securities and to file such
other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for
the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders allowed
in such judicial proceeding, and

 

(ii) to
collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same;

 

and any custodian, receiver, assignee,
trustee, liquidator, sequestrator (or other similar official) in any such judicial proceeding is hereby authorized by each Holder
of Securities of such series and coupons to make such payments to the Trustee, and in the event that the Trustee shall consent
to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation,
expenses, disbursements and advances of the Trustee and any predecessor Trustee, their agents and counsel, and any other amounts
due the Trustee or any predecessor Trustee under Section 606.

 

Nothing herein contained
shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder of a Security or
coupon any plan of reorganization, arrangement, adjustment or composition affecting the Securities or coupons or the rights of
any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder of a Security or coupon in any such
proceeding.

 

In any proceedings
brought by the Trustee (and also any proceedings involving the interpretation of any provision of this Indenture to which the Trustee
shall be a party) the Trustee shall be held to represent all the Holders of the Securities, and it shall not be necessary to make
any Holders of the Securities parties to any such proceedings.

 

SECTION 505. Trustee
May Enforce Claims Without Possession of Securities or Coupons. All rights of action and claims under this Indenture or
any of the Securities or coupons may be prosecuted and enforced by the Trustee without the possession of any of the Securities
or coupons or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall
be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment
of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable
benefit of the Holders of the Securities and coupons in respect of which such judgment has been recovered.

 

SECTION 506. Application
of Money Collected. Any money collected by the Trustee pursuant to this Article shall be applied in the following order,
at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal (or premium or
Make-Whole Amount, if any) or interest, upon presentation of the Securities or coupons, or both, as the case may be, and the notation
thereon of the payment if only partially paid and upon surrender thereof if fully paid:

 

    34

     

    

 

FIRST: To the payment
of all amounts due the Trustee and any predecessor Trustee under Section 606;

 

SECOND: To the payment
of the amounts then due and unpaid upon the Securities and coupons for principal (and premium or Make-Whole Amount, if any) and
interest, in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority
of any kind, according to the aggregate amounts due and payable on such Securities and coupons for principal (and premium or Make-Whole
Amount, if any) and interest, respectively; and

 

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

 

SECTION 507. Limitation
on Suits. No Holder of any Security of any series or any related coupon shall have any right to institute any proceeding,
judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy
hereunder, unless:

 

(1) such
Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to the Securities of that
series;

 

(2) the
Holders of not less than 25% in principal amount of the Outstanding Securities of that series shall have made written request to
the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder;

 

(3) such
Holder or Holders have offered to the Trustee indemnity reasonably satisfactory to the Trustee against the costs, expenses and
liabilities to be incurred in compliance with such request;

 

(4) the
Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding;
and

 

(5) no
direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority
in principal amount of the Outstanding Securities of that series;

 

it being understood and intended that no
one or more of such Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this
Indenture to affect, disturb or prejudice the rights of any other of such Holders, or to obtain or to seek to obtain priority or
preference over any other of such Holders or to enforce any right under this Indenture, except in the manner herein provided and
for the equal and ratable benefit of all such Holders.

 

SECTION 508. Unconditional
Right of Holders to Receive Principal, Premium or Make-Whole Amount, if any, and Interest. Notwithstanding any other provision
in this Indenture, the Holder of any Security or coupon shall have the right which is absolute and unconditional to receive payment
of the principal of (and premium or Make-Whole Amount, if any) and (subject to Sections 305 and 307) interest on such Security
or payment of such coupon on the respective due dates expressed in such Security or coupon (or, in the case of redemption, on the
Redemption Date) and to institute suit for the enforcement of any such payment, and such rights shall not be impaired without the
consent of such Holder.

 

SECTION 509. Restoration
of Rights and Remedies. If the Trustee or any Holder of a Security or coupon has instituted any proceeding to enforce any
right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined
adversely to the Trustee or to such Holder, then and in every such case, the Company, the Trustee and the Holders of Securities
and coupons shall, subject to any determination in such proceeding, be restored severally and respectively to their former positions
hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had
been instituted.

 

    35

     

    

 

SECTION 510. Rights
and Remedies Cumulative. Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed,
lost or stolen Securities or coupons in the last paragraph of Section 306, no right or remedy herein conferred upon or reserved
to the Trustee or to the Holders of Securities or coupons is intended to be exclusive of any other right or remedy, and every right
and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder
or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or
otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

 

SECTION 511. Delay
or Omission Not Waiver. No delay or omission of the Trustee 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.

 

SECTION 512. Control
by Holders of Securities. The Holders of not less than a majority in principal amount of the Outstanding Securities of
any series shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the
Trustee or exercising any trust or power conferred on the Trustee with respect to the Securities of such series, provided that:

 

(1) such
direction shall not be in conflict with any rule of law or with this Indenture,

 

(2) the
Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction, and

 

(3) the
Trustee need not take any action which might involve it in personal liability or be unduly prejudicial to the Holders of Securities
of such series not joining therein.

 

Nothing in this Indenture
shall impair the right of the Trustee in its discretion to take any action deemed proper by the Trustee and which is not inconsistent
with such direction by Holders.

 

SECTION 513. Waiver
of Past Defaults. The Holders of not less than a majority in principal amount of the Outstanding Securities of any series
may on behalf of the Holders of all the Securities of such series and any related coupons waive any past default hereunder with
respect to such series and its consequences, except a default

 

(1) in
the payment of the principal of (or premium or Make-Whole Amount, if any) or interest on any Security of such series or any related
coupons, or

 

(2) in
respect of a covenant or provision hereof which under Article Nine cannot be modified or amended without the consent of the Holder
of each Outstanding Security of such series affected; or

 

(3) in
respect of a covenant or provision hereof for the benefit or protection of the Trustee, without its express written consent.

 

    36

     

    

 

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

 

SECTION 514. Waiver
of Usury, 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 usury, stay or extension
law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture;
and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and
covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and
permit the execution of every such power as though no such law had been enacted.

 

SECTION 515. Undertaking
for Costs. All parties to this Indenture agree, and each Holder of any Security by his acceptance thereof shall be deemed
to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this
Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant
in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs,
including reasonable attorneys’ fees and expenses, against any party litigant in such suit having due regard to the merits
and good faith of the claims or defenses made by such party litigant; but the provisions of this Section shall not apply to any
suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10%
in principal amount of the Outstanding Securities of any series, or to any suit instituted by any Holder for the enforcement of
the payment of the principal of (or premium or Make-Whole Amount, if any) or interest on any Security on or after the respective
Stated Maturities expressed in such Security (or, in the case of redemption, on or after the Redemption Date).

 

ARTICLE
6.

THE TRUSTEE

 

SECTION 601. Notice
of Defaults. Within 90 days after the occurrence of any default hereunder with respect to the Securities of any series,
the Trustee shall transmit in the manner and to the extent provided in TIA Section 313(c), notice of such default hereunder known
to the Trustee, unless such default shall have been cured or waived; provided, however, that, except in the case of a default in
the payment of the principal of (or premium or Make-Whole Amount, if any) or interest on any Security of such series, or in the
payment of any sinking or purchase fund installment with respect to the Securities of such series, the Trustee shall be protected
in withholding such notice if and so long as the board of directors, the executive committee, or a trust committee of directors
and/or Responsible Officers of the Trustee in good faith determine that the withholding of such notice is in the interests of the
Holders of the Securities and coupons of such series; and provided further that in the case of any default or breach of the character
specified in Section 501(4) with respect to the Securities and coupons of such series, no such notice to Holders shall be given
until at least 60 days after the occurrence thereof. For the purpose of this Section, the term “default” means any
event which is, or after notice or lapse of time or both would become, an Event of Default with respect to the Securities of such
series.

 

SECTION 602. Certain
Rights of Trustee. Subject to the provisions of TIA Section 315(a) through 315(d):

 

(1) the
Trustee may conclusively rely and shall be fully protected in acting or refraining from acting upon any resolution, certificate,
statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, coupon or other paper
or document (whether in its original or facsimile form) reasonably believed by it to be genuine and to have been signed or presented
by the proper party or parties;

 

(2) any
request or direction of the Company mentioned herein shall be sufficiently evidenced by a Company Request or Company Order (other
than delivery of any Security, together with any coupons appertaining thereto, to the Trustee for authentication and delivery pursuant
to Section 303 which shall be sufficiently evidenced as provided therein) and any resolution of the Board of Directors may be sufficiently
evidenced by a Board Resolution;

 

    37

     

    

 

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

 

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

 

(5) the
Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction
of any of the Holders of Securities of any series or any related coupons pursuant to this Indenture, unless such Holders shall
have offered to the Trustee security or indemnity reasonably satisfactory to the Trustee against the costs, expenses and liabilities
which might be incurred by it in compliance with such request or direction;

 

(6) the
Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, coupon or other paper or document,
unless requested in writing so to do by the Holders of not less than a majority in aggregate principal amount of the Outstanding
Securities of any series; provided that, if the payment within a reasonable time to the Trustee of the costs, expenses or liabilities
likely to be incurred by it in the making of such investigation is, in the opinion of the Trustee, not reasonably assured to the
Trustee by the security afforded to it by the terms of this Indenture, the Trustee may require reasonable indemnity against such
expenses or liabilities as a condition to proceeding; the reasonable expenses of every such examination shall be paid by the Holders
or, if paid by the Trustee, shall be repaid by the Holders upon demand. The Trustee, in its discretion, may make such further inquiry
or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry
or investigation, it shall be entitled to examine the books, records and premises of the Company, relevant to the facts or matters
that are the subject of its inquiry, personally or by agent or attorney at the expense of the Company and shall incur no liability
or additional liability of any kind by reason of such inquiry or investigation;

 

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

 

(8) the
Trustee shall not be liable for any action taken, suffered or omitted by it in good faith and reasonably believed by it to be authorized
or within the discretion or rights or powers conferred upon it by this Indenture;

 

(9) any
permissive right or power available to the Trustee under this Indenture or any supplement hereto shall not be construed to be a
mandatory duty or obligation;

 

(10) the
Trustee shall not be charged with knowledge of any matter (including any default, other than as described in Section 501(1), (2)
or (3)) unless and except to the extent actually known to a Responsible Officer of the Trustee or to the extent written notice
thereof is received by the Trustee at the Corporate Trust Office;

 

    38

     

    

 

(11) the
Trustee shall have no liability for any inaccuracy in the books and records of, or for any actions or omissions of, DTC, Euroclear
or Clearstream or any depository acting on behalf of any of them;

 

(12) the
rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified,
are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and other
Person employed by the Trustee to act hereunder; and

 

(13) the
Trustee may request that the Company deliver an Officers’ Certificate setting forth the names of individuals and/or titles
of officers authorized at such time to take specified actions pursuant to this Indenture, which Officers’ Certificate may
be signed by any person authorized to sign an Officers’ Certificate, including any person specified as so authorized in any
such certificate previously delivered and not superseded.

 

The Trustee shall not
be required to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties
hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment
of such funds or adequate indemnity against such risk or liability is not reasonably assured to it.

 

Except during the continuance
of an Event of Default, the Trustee undertakes to perform only such duties as are specifically set forth in this Indenture, and
no implied covenants or obligations shall be read into this Indenture against the Trustee.

 

SECTION 603. Not
Responsible for Recitals or Issuance of Securities. The recitals contained herein and in the Securities, except the Trustee’s
certificate of authentication, and in any coupons shall be taken as the statements of the Company, and neither the Trustee nor
any Authenticating Agent assumes any responsibility for their correctness. The Trustee makes no representations as to the validity
or sufficiency of this Indenture or of the Securities or coupons, except that the Trustee represents that it is duly authorized
to execute and deliver this Indenture, authenticate the Securities and perform its obligations hereunder. Neither the Trustee nor
any Authenticating Agent shall be accountable for the use or application by the Company of Securities or the proceeds thereof.
The Trustee shall have no responsibility with respect to any information, statement or recital in any offering prospectus or other
disclosure materials prepared or distributed with respect to the Securities.

 

SECTION 604. May
Hold Securities. The Trustee, any Paying Agent, Security Registrar, Authenticating Agent or any other agent of the Company,
in its individual or any other capacity, may become the owner or pledgee of Securities and coupons and, subject to TIA Sections
310(b) and 311, may otherwise deal with the Company with the same rights it would have if it were not Trustee, Paying Agent, Security
Registrar, Authenticating Agent or such other agent.

 

SECTION 605. Money
Held in Trust. Money held by the Trustee in trust hereunder need not be segregated from other funds except to the extent
required by law. The Trustee shall be under no liability for interest on any money received by it hereunder except as otherwise
agreed in writing with the Company.

 

    39

     

    

 

SECTION 606. Compensation
and Reimbursement. The Company agrees:

 

(1) to
pay to the Trustee as agreed upon in writing from time to time reasonable compensation for all services rendered by it hereunder
(which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust);

 

(2) except
as otherwise expressly provided herein, to reimburse each of the Trustee and any predecessor Trustee upon its request for all reasonable
expenses, and disbursements incurred by the Trustee in accordance with any provision of this Indenture (including the reasonable
compensation and the reasonable expenses and disbursements of its agents and counsel), except any such expense or disbursement
as shall be determined to have been caused by its own negligence, willful misconduct or bad faith; and

 

(3) to
indemnify each of the Trustee and any predecessor Trustee for, and to hold it harmless against, any loss, liability, claim, damage
or expense incurred without negligence, willful misconduct or bad faith on its part, arising out of or in connection with the acceptance
or administration of the trust or trusts hereunder, including the costs and expenses of defending itself against any claim or liability
in connection with the exercise or performance of any of its powers or duties hereunder.

 

When the Trustee incurs
expenses or renders services in connection with an Event of Default specified in Section 501(6) or Section 501(7), the expenses
(including the reasonable charges and expenses of its counsel) and the compensation for the services are intended to constitute
expenses of administration under any applicable Federal or state bankruptcy, insolvency or other similar law.

 

As security for the
performance of the obligations of the Company under this Section, the Trustee shall have a lien for payment of the Trustee’s
fees and expenses prior to the Securities upon all property and funds held or collected by the Trustee as such, except funds held
in trust for the payment of principal of (or premium or Make-Whole Amount, if any) or interest on particular Securities or any
coupons.

 

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

to act as Trustee under TIA Section 310(a)(1) and shall have at all times a combined capital and surplus of at least $50,000,000
(or which shall have a combined capital and surplus of at least $10,000,000 and whose ultimate parent holding company shall have
a combined capital and surplus of at least $50,000,000). If the Trustee publishes reports of condition at least annually, pursuant
to law or the requirements of Federal, state, territorial or District of Columbia supervising or examining authority, then for
the purposes of this Section, the combined capital and surplus of the Trustee shall be deemed to be its combined capital and surplus
as set forth in its most recent report of condition so published. If at any time the Trustee shall cease to be eligible in accordance
with the provisions of this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this
Article. Neither the Company nor any Person directly or indirectly controlling, controlled by, or under common control with the
Company shall serve as Trustee.

 

SECTION 608. Resignation
and Removal; Appointment of Successor.

 

(a) No
resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this Article shall become effective
until the acceptance of appointment by the successor Trustee in accordance with the applicable requirements of Section 609.

 

(b) The
Trustee may resign at any time with respect to the Securities of one or more series by giving written notice thereof to the Company.
If an instrument of acceptance by a successor Trustee shall not have been delivered to the Trustee within 60 days after the giving

for the appointment of a successor Trustee.

 

    40

     

    

 

(c) The
Trustee may be removed at any time with respect to the Securities of any series by Act of the Holders of a majority in principal
amount of the Outstanding Securities of such series delivered to the Trustee and to the Company. If an instrument of acceptance
by a successor Trustee shall not have been delivered to the Trustee within 60 days after the giving of such notice of resignation,
the resigning Trustee may petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a
successor Trustee.

 

(d) If
at any time:

 

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

 

(2) the
Trustee shall cease to be eligible under Section 607 and shall fail to resign after written request therefor by the Company or
by any Holder of a Security who has been a bona fide Holder of a Security for at least six months, or

 

(3) the
Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent or a receiver of the Trustee or of its property
shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose
of rehabilitation, conservation or liquidation,

 

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

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.

Holders of Securities in Section 106. Each notice shall include the name of the successor Trustee with respect to the Securities
of such series and the address of its Corporate Trust Office.

 

    41

     

    

 

SECTION 609. Acceptance
of Appointment by Successor.

 

(a) In
case of the appointment hereunder of a successor Trustee with respect to all Securities, every such successor Trustee so appointed
shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and
thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further
act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on request
of the Company or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an instrument
transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee, and shall duly assign, transfer
and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder, subject nevertheless to its
claim, if any, provided for in Section 606.

 

(b) In
case of the appointment hereunder of a successor Trustee with respect to the Securities of one or more (but not all) series, the
Company, the retiring Trustee and each successor Trustee with respect to the Securities of one or more series shall execute and
deliver an indenture supplemental hereto, pursuant to Article Nine hereof, wherein each successor Trustee shall accept such appointment
and which (1) shall contain such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each
successor Trustee all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those
series to which the appointment of such successor Trustee relates, (2) if the retiring Trustee is not retiring with respect to
all Securities, shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that or those series as to which the retiring Trustee
is not retiring shall continue to be vested in the retiring Trustee, and (3) shall add to or change any of the provisions of this
Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee,
it being understood that nothing herein or in such supplemental indenture shall constitute such Trustees co-trustees of the same
trust and that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder
administered by any other such Trustee; and upon the execution and delivery of such supplemental indenture the resignation or removal
of the retiring Trustee shall become effective to the extent provided therein and each such successor Trustee, without any further
act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee with respect
to the Securities of that or those series to which the appointment of such successor Trustee relates; but, on request of the Company
or any successor Trustee, such retiring Trustee shall duly assign, transfer and deliver to such successor Trustee all property
and money held by such retiring Trustee hereunder with respect to the Securities of that or those series to which the appointment
of such successor Trustee relates.

 

(c) Upon
request of any such successor Trustee, the Company shall execute any and all instruments for more fully and certainly vesting in
and confirming to such successor Trustee all such rights, powers and trusts referred to in paragraph (a) or (b) of this Section
609, as the case may be.

 

(d) No
successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified
and eligible under this Article.

 

    42

     

    

 

SECTION 610. Merger,
Conversion, Consolidation or Succession to Business. Any corporation into which the Trustee may be merged or converted
or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee
shall be a party, or any corporation succeeding to all or substantially all of the corporate trust business of the Trustee, shall
be the successor of the Trustee hereunder, provided such corporation shall be otherwise qualified and eligible under this Article,
without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Securities
or coupons shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion
or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities or coupons so authenticated
with the same effect as if such successor Trustee had itself authenticated such Securities or coupons. In case any Securities or
coupons shall not have been authenticated by such predecessor Trustee, any such successor Trustee may authenticate and deliver
such Securities or coupons, in either its own name or that of its predecessor Trustee, with the full force and effect which this
Indenture provides for the certificate of authentication of the Trustee.

 

SECTION 611. Appointment
of Authenticating Agent. At any time when any of the Securities remain Outstanding, the Trustee may appoint an Authenticating
Agent or Agents with respect to one or more series of Securities which shall be authorized to act on behalf of the Trustee to authenticate
Securities of such series issued upon conversion or exchange, registration of transfer or partial redemption or repayment 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 shall at all times be a bank or trust company or corporation organized and doing business and in
good standing under the laws of the United States of America or of any state or the District of Columbia, authorized under such
laws to act as Authenticating Agent, having a combined capital and surplus of not less than $50,000,000 and subject to supervision
or examination by Federal or state authorities. If such Authenticating Agent publishes reports of condition at least annually,
pursuant to law or the requirements of the aforesaid supervising or examining authority, then for the purposes of this Section,
the combined capital and surplus of such Authenticating Agent shall be deemed to be its combined capital and surplus as set forth
in its most recent report of condition so published. In case at any time an Authenticating Agent shall cease to be eligible in
accordance with the provisions of this Section, such Authenticating Agent shall resign immediately in the manner and with the effect
specified in this Section.

 

Any corporation into
which an Authenticating Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from
any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to the
corporate agency or corporate trust business of an Authenticating Agent, shall continue to be an Authenticating Agent, provided
such corporation shall be otherwise eligible under this Section, without the execution or filing of any paper or further act on
the part of the Trustee or the Authenticating Agent.

 

An Authenticating Agent
for any series of Securities may at any time resign by giving written notice of resignation to the Trustee for such series and
to the Company. The Trustee for any series of Securities may at any time terminate the agency of an Authenticating Agent by giving
written notice of termination to such Authenticating Agent and to the Company. Upon receiving such a notice of resignation or upon
such a termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions
of this Section, the Trustee for such series may appoint a successor Authenticating Agent which shall be acceptable to the Company
and shall give notice of such appointment to all Holders of Securities of the series with respect to which such Authenticating
Agent will serve in the manner set forth in Section 106. Any successor Authenticating Agent upon acceptance of its appointment
hereunder shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally
named as an Authenticating Agent herein. No successor Authenticating Agent shall be appointed unless eligible under the provisions
of this Section.

 

    43

     

    

 

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, subject to Section 606.

 

If an appointment with
respect to one or more series is made pursuant to this Section, the Securities of such series may have endorsed thereon, in addition
to or in lieu of the Trustee’s certificate of authentication, an alternate certificate of authentication substantially in
the following form:

 

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

respect to the Securities of any series, except during the continuance of an Event of Default with respect to the Securities of

(1) the
Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Indenture, and no implied
covenants or obligations shall be read into this Indenture against the Trustee; and

 

(2) in
the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness
of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of
this Indenture; but in the case of any such certificates or opinions which by any provision hereof are specifically required to
be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to
the requirements of this Indenture, but shall not be under any duty to verify the contents or accuracy thereof.

 

(b) In
case an Event of Default with respect to the Securities of any series has occurred and is continuing, the Trustee shall, with respect
to Securities of such series, exercise such of the rights and powers vested in it by this Indenture, and use the same degree of
care and skill in their exercise, as a prudent man would exercise or use under the circumstances in the conduct of his own affairs.

 

    44

     

    

 

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

 

(1) this
Subsection shall not be construed to limit the effect of Subsection (a) of this Section;

 

(2) the
Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it shall be proved that
the Trustee was negligent in ascertaining the pertinent facts;

 

(3) the
Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the
direction of the Holders of a majority in principal amount of the Outstanding Securities of any series relating to the time, method
and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon
the Trustee, under this Indenture with respect to the Securities of such series; and

 

(4) no
provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability
in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable
grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured
to it; and, the Trustee shall be under no obligation to exercise any of its rights and powers under this Indenture at the request
of any Holder, unless such Holder shall have offered to the Trustee security and indemnity satisfactory to it against any loss,
liability or expense.

 

(d) Whether
or not therein expressly so provided, every provision of this Indenture relating to the conduct or affecting the liability of or
affording protection to the Trustee shall be subject to the provisions of this Section 612.

 

(e) The
Trustee shall not be liable for interest on any money or assets held by it except to the extent the Trustee may agree in writing
with the Company. Assets held in trust by the Trustee need not be segregated from other assets except to the extent required by
law.

series are convertible) adversely affect the right of the Holder to convert any Security as provided in Article Sixteen; or

 

(2) reduce
the percentage in principal amount of the Outstanding Securities of any series, the consent of whose Holders is required for any
such supplemental indenture, or the consent of whose Holders is required for any waiver with respect to such series (or compliance
with certain provisions of this Indenture or certain defaults hereunder and their consequences) provided for in this Indenture,
or reduce the requirements of Section 1504 for quorum or voting, or

 

(3) modify
any of the provisions of this Section, Section 513 or Section 1009, except to increase the required percentage to effect such action
or to provide that certain other provisions of this Indenture cannot be modified or waived without the consent of the Holder of
each Outstanding Security affected thereby, provided, however, that this clause shall not be deemed to require the consent of any
Holder with respect to changes in the references to “the Trustee” and concomitant changes in this Section 902 and Section
1009, or the deletion of this proviso, in accordance with the requirements of Sections 609(b) and 901(8).

 

    49

     

    

 

It shall not be necessary
for any Act of Holders under this Section 902 to approve the particular form of any proposed supplemental indenture, but it shall
be sufficient if such Act shall approve the substance thereof.

 

A supplemental indenture
which changes or eliminates any covenant or other provision of this Indenture which has expressly been included solely for the
benefit of one or more particular series of Securities, or which modifies the rights of the Holders of Securities of such series
with respect to such covenant or other provision, shall be deemed not to affect the rights under this Indenture of the Holders
of Securities of any other series.

 

SECTION 903. Execution
of Supplemental Indentures. In executing, or accepting the additional trusts created by, any supplemental indenture permitted
by this Article or the modification thereby of the trusts created by this Indenture, the Trustee shall be entitled to receive,
and (subject to Section 612) shall be fully protected in relying upon, an Opinion of Counsel stating that the execution of such
supplemental indenture is authorized or permitted by this Indenture. The Trustee may, but shall not be obligated to, enter into
any such supplemental indenture which affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise.

 

SECTION 904. Effect
of Supplemental Indentures. Upon the execution of any supplemental indenture under this Article, this Indenture shall be
modified in accordance therewith, and such supplemental indenture shall form a part of this Indenture for all purposes; and every
Holder of Securities theretofore or thereafter authenticated and delivered hereunder and of any coupon appertaining thereto shall
be bound thereby.

 

SECTION 905. Conformity
with Trust Indenture Act. Every supplemental indenture executed pursuant to this Article shall conform to the requirements
of the Trust Indenture Act as then in effect.

 

SECTION 906. Reference
in Securities to Supplemental Indentures. Securities of any series authenticated and delivered after the execution of any
supplemental indenture pursuant to this Article may, and shall, if required by the Trustee, bear a notation in form approved by
the Trustee as to any matter provided for in such supplemental indenture. If the Company shall so determine, new Securities of
any series so modified as to conform, in the opinion of the Trustee and the Company, to any such supplemental indenture may be
prepared and executed by the Company and authenticated and delivered by the Trustee in exchange for Outstanding Securities of such
series.

COVENANTS

 

SECTION 1001. Payment
of Principal, Premium or Make-Whole Amount, if any; and Interest. The Company covenants and agrees for the benefit of the
Holders of each series of Securities that it will duly and punctually pay the principal of (and premium or Make-Whole Amount, if
any) and interest on the Securities of that series in accordance with the terms of such series of Securities, any coupons appertaining
thereto and this Indenture. Unless otherwise specified as contemplated by Section 301 with respect to any series of Securities,
any interest due on Bearer Securities on or before Maturity shall be payable only upon presentation and surrender of the several
coupons for such interest installments as are evidenced thereby as they severally mature. Unless otherwise specified with respect
to Securities of any series pursuant to Section 301, at the option of the Company (upon written notice to the Trustee), all payments
of principal may be paid by check to the registered Holder of the Registered Security or other Person entitled thereto against
surrender of such Security.

 

    50

     

    

 

SECTION 1002. Maintenance
of Office or Agency. If Securities of a series are issuable only as Registered Securities, the Company shall maintain in
each Place of Payment for any series of Securities an office or agency where Securities of that series may be presented or surrendered
for payment or conversion, where Securities of that series may be surrendered for registration of transfer or conversion or exchange
and where notices and demands to or upon the Company in respect of the Securities of that series and this Indenture may be served.
If Securities of a series are issuable as Bearer Securities, the Company will maintain: (A) in the Borough of Manhattan, The City
of New York, an office or agency where any Registered Securities of that series may be presented or surrendered for payment or
conversion, where any Registered Securities of that series may be surrendered for registration of transfer, where Securities of
that series may be surrendered for conversion or exchange, where notices and demands to or upon the Company in respect of the Securities
of that series and this Indenture may be served and where Bearer Securities of that series and related coupons may be presented
or surrendered for payment or conversion in the circumstances described in the following paragraph (and not otherwise); (B) subject
to any laws or regulations applicable thereto, in a Place of Payment for that series which is located outside the United States,
an office or agency where Securities of that series and related coupons may be presented and surrendered for payment; provided,
however, that if the Securities of that series are listed on any stock exchange located outside the United States and such stock
exchange shall so require, the Company will maintain a Paying Agent for the Securities of that series in any required city located
outside the United States, as the case may be, so long as the Securities of that series are listed on such exchange; and (C) subject
to any laws or regulations applicable thereto, in a Place of Payment for that series located outside the United States an office
or agency where any Registered Securities of that series may be surrendered for registration of transfer, where Securities of that
series may be surrendered for conversion or exchange and where notices and demands to or upon the Company in respect of the Securities
of that series and this Indenture may be served. The Company will give prompt written notice to the Trustee of the location, and
any change in the location, of each such office or agency. If at any time the Company shall fail to maintain any such required
office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands
may be made or served at the Corporate Trust Office of the Trustee, except that Bearer Securities of that series and the related
coupons may be presented and surrendered for payment or conversion at the offices specified in the Security, in London, England,
and the Company hereby appoints the same as its agent to receive such respective presentations, surrenders, notices and demands,
and the Company hereby appoints the Trustee its agent to receive all such presentations, surrenders, notices and demands.

 

Unless otherwise specified
with respect to any Securities pursuant to Section 301, no payment of principal, premium or Make-Whole Amount or interest on Bearer
Securities shall be made at any office or agency of the Company in the United States or by check mailed to any address in the United
States or by transfer to an account maintained with a bank located in the United States; provided, however, that, if the Securities
of a series are payable in Dollars, payment of principal of and any premium or Make-Whole Amount and interest on any Bearer Security
shall be made at the office of the Company’s Paying Agent in the Borough of Manhattan, The City of New York, if (but only
if) payment in Dollars of the full amount of such principal, premium or Make-Whole Amount, or interest, as the case may be, at
all offices or agencies outside the United States maintained for the purpose by the Company in accordance with this Indenture,
is illegal or effectively precluded by exchange controls or other similar restrictions.

 

The Company may from
time to time designate one or more other offices or agencies (in or outside the Place of Payment) 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 301 with respect to a series
of Securities, the Company hereby designates as a Place of Payment for each series of Securities, each of (i) the office or agency
of the Company in the Borough of Manhattan, The City of New York, and (ii) the Corporate Trust Office of the Trustee (as Paying
Agent); and the Company hereby initially appoints the Trustee at its Corporate Trust Office as Paying Agent in such city; and the
Company hereby initially appoints as its agent to receive all such presentations, surrenders, notices and demands each of the Trustee,
at its Corporate Trust Office.

Unless otherwise specified
with respect to any Securities pursuant to Section 301, if and so long as the Securities of any series (i) are denominated in a
Foreign Currency or (ii) may be payable in a Foreign Currency, or so long as it is required under any other provision of the Indenture,
then the Company will maintain with respect to each such series of Securities, or as so required, at least one exchange rate agent
(of which it shall give written notice to the Trustee).

 

SECTION 1003. Money
for Securities Payments to Be Held in Trust. If the Company shall at any time act as its own Paying Agent with respect
to any series of any Securities and any related coupons, it will, on or before each due date of the principal of (and premium or
Make-Whole Amount, if any), or interest on any of the Securities of that series, segregate and hold in trust for the benefit of
the Persons entitled thereto a sum in the currency or currencies, currency unit or units or composite currency or currencies in
which the Securities of such series are payable (except as otherwise specified pursuant to Section 301 for the Securities of such
series) sufficient to pay the principal (and premium or Make-Whole Amount, if any) or interest so becoming due until such sums
shall be paid to such Persons or otherwise disposed of as herein provided, and will promptly notify the Trustee of its action or
failure so to act.

 

Whenever the Company
shall have one or more Paying Agents for any series of Securities and any related coupons, it will, on or before each due date
of the principal of (and premium or Make-Whole Amount, if any), or interest on any Securities of that series, deposit with a Paying
Agent a sum (in the currency or currencies, currency unit or units or composite currency or currencies described in the preceding
paragraph) sufficient to pay the principal (and premium or Make-Whole Amount, if any) or interest so becoming due, such sum to
be held in trust for the benefit of the Persons entitled to such principal, premium or Make-Whole Amount, if any, or interest and
(unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of its action or failure so to act.

 

The Company will cause
each Paying Agent for any series of Securities other than the Trustee to execute and deliver to the Trustee an instrument in which
such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent will

 

(1) hold
all sums held by it for the payment of principal of (and premium or Make-Whole Amount, if any) or interest on Securities in trust
for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as herein
provided;

 

(2) give
the Trustee notice of any default by the Company (or any other obligor upon the Securities) in the making of any such payment of
principal (and premium or Make-Whole Amount, if any) or interest on the Securities of that series; and

 

(3) at
any time during the continuance of any such default upon the written request of the Trustee, forthwith pay to the Trustee all sums
so held in trust by such Paying Agent.

 

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

 

    52

     

    

 

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

 

SECTION 1004. Existence.
Subject to Article Eight, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect
its corporate existence, all material rights (by articles of incorporation, by-laws and statute) and material franchises; provided,
however, that the Company shall not be required to preserve any such right or franchise if the Board of Directors shall determine
that the preservation thereof is no longer desirable in the conduct of the business of the Company.

 

SECTION 1005. Maintenance
of Properties. The Company will cause all of its material properties used or useful in the conduct of its business or the
business of any Subsidiary to be maintained and kept in good condition, repair and working order, normal wear and tear, casualty
and condemnation excepted, and supplied with all necessary equipment and will cause to be made all necessary repairs, renewals,
replacements, betterments and improvements thereof (and the Company may take out of service for a period of time, any of its properties
that have been condemned or suffered any loss due to casualty in order to make such repairs, betterments and improvements), all
as in the judgment of the Company may be necessary so that the business carried on in connection therewith may be properly and
advantageously conducted at all times; provided, however, that the Company and its Subsidiaries shall not be prevented from (i)
removing permanently any property that has been condemned or suffered a loss due to casualty based on the Company’s reasonable
judgment that such removal is in the best interest of the Company, or (ii) selling or otherwise disposing of their properties for
value in the ordinary course of business.

 

SECTION 1006. Insurance.
The Company will cause each of its and its Subsidiaries’ insurable properties to be insured against loss or damage in an
amount deemed reasonable by the Board of Directors with insurers of recognized responsibility.

 

SECTION 1007. Payment
of Taxes and Other Claims. The Company will pay or discharge or cause to be paid or discharged, before the same shall become
delinquent, (1) all taxes, assessments and governmental charges levied or imposed upon it or any Subsidiary or upon the income,
profits or property of the Company or any Subsidiary, and (2) all lawful claims for labor, materials and supplies which, if unpaid,
might by law become a lien upon the property of the Company or any Subsidiary; provided, however, that the Company shall not be
required to pay or discharge or cause to be paid or discharged any such tax, assessment, charge or claim whose amount, applicability
or validity is being contested in good faith by appropriate proceedings.

 

    53

     

    

 

SECTION 1008. Statement
as to Compliance. The Company will deliver to the Trustee, within 120 days after the end of each fiscal year, a brief certificate
from the principal executive officer, principal financial officer or principal accounting officer as to his or her knowledge of
the Company’s compliance with all conditions and covenants under this Indenture and, in the event of any noncompliance, specifying
such noncompliance and the nature and status thereof. For purposes of this Section 1008, such compliance shall be determined without
regard to any period of grace or requirement of notice under this Indenture.

 

SECTION 1009. Waiver
of Certain Covenants. The Company may omit in any particular instance to comply with any term, provision or condition set
forth in Sections 1004 to 1008, inclusive, if before or after the time for such compliance the Holders of at least a majority in
principal amount of all outstanding Securities of such series, by Act of such Holders, either waive such compliance in such instance
or generally waive compliance with such covenant or condition, but no such waiver shall extend to or affect such covenant or condition
except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the
duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect.

REDEMPTION OF SECURITIES

 

SECTION 1101. Applicability
of Article. Securities of any series which are redeemable before their Stated Maturity shall be redeemable in accordance
with their terms and (except as otherwise specified as contemplated by Section 301 for Securities of any series) in accordance
with this Article.

 

SECTION 1102. Election
to Redeem; Notice to Trustee. The election of the Company to redeem any Securities 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 45 days prior to the giving of the notice of redemption in Section 1104 (unless a shorter notice shall
be satisfactory to the Trustee), notify the Trustee of such Redemption Date and of the principal amount of Securities of such series
to be redeemed. In the case of any redemption of Securities prior to the expiration of any restriction on such redemption provided
in the terms of such Securities or elsewhere in this Indenture, the Company shall furnish the Trustee with an Officers’ Certificate
evidencing compliance with such restriction.

 

SECTION 1103. 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 and which may provide for the selection for redemption
of portions (equal to the minimum authorized denomination for Securities of that series or any integral multiple thereof) of the
principal amount of Securities of such series of a denomination larger than the minimum authorized denomination for Securities
of that series.

 

The Trustee shall 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.

 

    54

     

    

 

SECTION 1104. Notice
of Redemption. Notice of redemption shall be given in the manner provided in Section 106, not less than 30 days nor more
than 60 days prior to the Redemption Date, unless a shorter period is specified by the terms of such series established pursuant
to Section 301, to each Holder of Securities to be redeemed, but failure to give such notice in the manner herein provided to the
Holder of any Security designated for redemption as a whole or in part, or any defect in the notice to any such Holder, shall not
affect the validity of the proceedings for the redemption of any other such Security or portion thereof.

 

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

 

All notices of redemption
shall state:

 

(1) the
Redemption Date,

 

(2) the
Redemption Price, accrued interest to the Redemption Date payable as provided in Section 1106, if any,

 

(3) if
less than all Outstanding Securities of any series are to be redeemed, the identification (and, in the case of partial redemption,
the principal amount) of the particular Security or Securities to be redeemed,

 

(4) in
case any Security is to be redeemed in part only, 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 to the Redemption Date payable as provided in Section 1106, if
any, will become due and payable upon each such Security, or the portion thereof, to be redeemed and, if applicable, that interest
thereon shall cease to accrue on and after said date,

 

(6) the
Place or Places of Payment where such Securities, together in the case of Bearer Securities with all coupons appertaining thereto,
if any, maturing after the Redemption Date, are to be surrendered for payment of the Redemption Price and accrued interest, if
any, or for conversion,

 

(7) that
the redemption is for a sinking fund, if such is the case,

 

(8) that,
unless otherwise specified in such notice, Bearer Securities of any series, if any, surrendered for redemption must be accompanied
by all coupons maturing subsequent to the date fixed for redemption or the amount of any such missing coupon or coupons will be
deducted from the Redemption Price, unless security or indemnity satisfactory to the Company, the Trustee for such series and any
Paying Agent is furnished,

 

(9) if
Bearer Securities of any series are to be redeemed and any Registered Securities of such series are not to be redeemed, and if
such Bearer Securities may be exchanged for Registered Securities not subject to redemption on this Redemption Date pursuant to
Section 305 or otherwise, the last date, as determined by the Company, on which such exchanges may be made, the CUSIP number of
such Security, if any, and

 

(10) if
applicable, that a Holder of Securities who desires to convert Securities for redemption must satisfy the requirements for conversion
contained in such Securities, the then existing conversion price or rate, the place or places where such Securities may be surrendered
for conversion, and the date and time when the option to convert shall expire.

 

    55

     

    

 

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

 

SECTION 1105. Deposit
of Redemption Price. On or prior to any Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent
(or, if the Company is acting as its own Paying Agent, which it may not do in the case of a sinking fund payment under Article
Twelve, segregate and hold in trust as provided in Section 1003) an amount of money in the currency or currencies, currency unit
or units or composite currency or currencies in which the Securities of such series are payable (except as otherwise specified
pursuant to Section 301 for the Securities of such series) sufficient to pay on the Redemption Date the Redemption Price of, and
(except if the Redemption Date shall be an Interest Payment Date) accrued interest on, all the Securities or portions thereof which
are to be redeemed on that date.

 

If any Securities called
for redemption are converted, any money deposited with the Trustee or with any Paying Agent or so segregated and held in trust
for the redemption of such Security shall be paid to the Company upon Company Request or, if then held by the Company, shall be
discharged from such trust.

 

SECTION 1106. Securities
Payable on Redemption Date. Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall,
on the Redemption Date, become due and payable at the Redemption Price therein specified in the currency or currencies, currency
unit or units or composite currency or currencies in which the Securities of such series are payable (except as otherwise specified
pursuant to Section 301 for the Securities of such series) (together with accrued interest, if any, to the Redemption Date), and
from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued interest) such Securities
shall, if the same were interest-bearing, cease to bear interest and the coupons for such interest appertaining to any Bearer Securities
so to be redeemed, except to the extent provided below, shall be void. Upon surrender of any such Security for redemption in accordance
with said notice, together with all coupons, if any, appertaining thereto maturing after the Redemption Date, such Security shall
be paid by the Company at the Redemption Price, together with accrued interest, if any, to the Redemption Date; provided, however,
that installments of interest on Bearer Securities whose Stated Maturity is on or prior to the Redemption Date shall be payable
only at an office or agency located outside the United States (except as otherwise provided in Section 1002) and, unless otherwise
specified as contemplated by Section 301, only upon presentation and surrender of coupons for such interest; and provided further
that except as otherwise provided with respect to Securities convertible into the Company’s Common Stock or Preferred Stock,
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 307.

 

    56

     

    

 

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 1002) and,
unless otherwise specified as contemplated by Section 301, only upon presentation and surrender of those coupons.

 

If any Security called
for redemption shall not be so paid upon surrender thereof for redemption, the principal (and premium or Make-Whole Amount, if
any) shall, until paid, bear interest from the Redemption Date at the rate borne by the Security.

 

SECTION 1107. Securities
Redeemed in Part. Any 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 his attorney duly authorized in writing) and the Company shall execute and the Trustee shall authenticate and deliver
to the Holder of such Security without service charge a new Security or Securities of the same series, of any authorized denomination
as requested by such Holder in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal
of the Security so surrendered. If a Global Security is so surrendered, the Company shall execute and the Trustee shall authenticate
and deliver to the depository, without service charge, a new Global Security in a denomination equal to and in exchange for the
unredeemed portion of the principal of the Global Security so surrendered.

SINKING FUNDS

 

SECTION 1201. Applicability
of Article. The provisions of this Article shall be applicable to any sinking fund for the retirement of Securities of
a series except as otherwise specified as contemplated by Section 301 for Securities of such series.

 

The minimum amount
of any sinking fund payment provided for by the terms of Securities of any series is herein referred to as a “mandatory sinking
fund payment,” and any payment in excess of such minimum amount provided for by the terms of such Securities of any series
is herein referred to as an “optional sinking fund payment.” If provided for by the terms of any Securities of any
series, the cash amount of any mandatory sinking fund payment may be subject to reduction as provided in Section 1202. Each sinking
fund payment shall be applied to the redemption of Securities of any series as provided for by the terms of Securities of such
series.

 

SECTION 1202. Satisfaction
of Sinking Fund Payments with Securities. The Company may, in satisfaction of all or any part of any mandatory sinking
fund payment with respect to the Securities of a series, (1) deliver Outstanding Securities of such series (other than any previously
called for redemption) together in the case of any Bearer Securities of such series with all unmatured coupons appertaining thereto
and (2) apply as a credit Securities of such series which have been redeemed either at the election of the Company pursuant to
the terms of such Securities or through the application of permitted optional sinking fund payments pursuant to the terms of such
Securities, as provided for by the terms of such Securities, or which have otherwise been acquired by the Company; provided that
such Securities so delivered or applied as a credit have not been previously so credited. Such Securities shall be received and
credited for such purpose by the Trustee at the applicable Redemption Price specified in such Securities for redemption through
operation of the sinking fund and the amount of such mandatory sinking fund payment shall be reduced accordingly.

 

SECTION 1203. Redemption
of Securities for Sinking Fund. Not less than 60 days prior to each sinking fund payment date for Securities of any series,
the Company will deliver to the Trustee an Officers’ Certificate specifying the amount of the next ensuing mandatory sinking
fund payment for that series pursuant to the terms of that series, the portion thereof, if any, which is to be satisfied by payment
of cash in the currency or currencies, currency unit or units or composite currency or currencies in which the Securities of such
series are payable (except as otherwise specified pursuant to Section 301 for the Securities of such series) and the portion thereof,
if any, which is to be satisfied by delivering and crediting Securities of that series pursuant to Section 1202, and the optional
amount, if any, to be added in cash to the next ensuing mandatory sinking fund payment, and will also deliver to the Trustee any
Securities to be so delivered and credited. If such Officers’ Certificate shall specify an optional amount to be added in
cash to the next ensuing mandatory sinking fund payment, the Company shall thereupon be obligated to pay the amount therein specified.
Not less than 30 days before each such sinking fund payment date the Trustee shall select the Securities to be redeemed upon such
sinking fund payment date in the manner specified in Section 1103 and cause notice of the redemption thereof to be given in the
name of and at the expense of the Company in the manner provided in Section 1104. Such notice having been duly given, the redemption
of such Securities shall be made upon the terms and in the manner stated in Sections 1106 and 1107.

SECTION 1302. Repayment
of Securities. Securities of any series subject to repayment in whole or in part at the option of the Holders thereof will,
unless otherwise provided in the terms of such Securities, be repaid at a price equal to the principal amount 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 prior to the Repayment Date it will deposit with the Trustee or with a Paying Agent (or, if the Company is
acting as its own Paying Agent, segregate and hold in trust as provided in Section 1003) an amount of money in the currency or
currencies, currency unit or units or composite currency or currencies in which the Securities of such series are payable (except
as otherwise specified pursuant to Section 301 for the Securities of such series) sufficient to pay the principal (or, if so provided
by the terms of the Securities of any series, a percentage of the principal) of, and (except if the Repayment Date shall be an
Interest Payment Date) accrued interest on, all the Securities or portions thereof, as the case may be, to be repaid on such date.

 

SECTION 1303. Exercise
of Option. Securities of any series subject to repayment at the option of the Holders thereof will contain an “Option
to Elect Repayment” form on the reverse of such Securities. In order for any Security to be repaid at the option of the Holder,
the Trustee must receive at the Place of Payment therefor specified in the terms of such Security (or at such other place or places
of which the Company shall from time to time notify the Holders of such Securities) not earlier than 60 days nor later than 30
days prior to the Repayment Date (1) the Security so providing for such repayment together with the “Option to Elect Repayment”
form on the reverse thereof duly completed by the Holder (or by the Holder’s attorney duly authorized in writing) or (2)
a telegram, telex, facsimile transmission or a letter from a member of a national securities exchange, or the FINRA, or a commercial
bank or trust company in the United States setting forth the name of the Holder of the Security, the principal amount of the Security,
the principal amount of the Security to be repaid, the CUSIP number, if any, or a description of the tenor and terms of the Security,
a statement that the option to elect repayment is being exercised thereby and a guarantee that the Security to be repaid, together
with the duly completed form entitled “Option to Elect Repayment” on the reverse of the Security, will be received
by the Trustee not later than the fifth Business Day after the date of such telegram, telex, facsimile transmission or letter;
provided, however, that such telegram, telex, facsimile transmission or letter shall only be effective if such Security and form
duly completed are received by the Trustee by such fifth Business Day. If less than the entire principal amount of such Security
is to be repaid in accordance with the terms of such Security, the principal amount of such Security to be repaid, in increments
of the minimum denomination for Securities of such series, and the denomination or denominations of the Security or Securities
to be issued to the Holder for the portion of the principal amount of such Security surrendered that is not to be repaid, must
be specified. The principal amount of any Security providing for repayment at the option of the Holder thereof may not be repaid
in part if, following such repayment, the unpaid principal amount of such Security would be less than the minimum authorized denomination
of Securities of 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.

 

    58

     

    

 

SECTION 1304. When
Securities Presented for Repayment Become Due and Payable. If Securities of any series providing for repayment at the option
of the Holders thereof shall have been surrendered as provided in this Article and as provided by or pursuant to the terms of such
Securities, such Securities or the portions thereof, as the case may be, to be repaid shall become due and payable and shall be
paid by the Company on the Repayment Date therein specified, and on and after such Repayment Date (unless the Company shall default
in the payment of such Securities on such Repayment Date) such Securities shall, if the same were interest-bearing, cease to bear
interest and the coupons for such interest appertaining to any Bearer Securities so to be repaid, except to the extent provided
below, shall be void. Upon surrender of any such Security for repayment in accordance with such provisions, together with all coupons,
if any, appertaining thereto maturing after the Repayment Date, the principal amount of such Security so to be repaid shall be
paid by the Company, together with accrued interest, if any, to the Repayment Date; provided, however, that coupons whose Stated
Maturity is on or prior to the Repayment Date shall be payable only at an office or agency located outside the United States (except
as otherwise provided in Section 1002) and, unless otherwise specified pursuant to Section 301, only upon presentation and surrender
of such coupons; and provided further that, in the case of Registered Securities, installments of interest, if any, whose Stated
Maturity is on or prior to the Repayment Date shall be payable (but without interest thereon, unless the Company shall default
in the payment thereof) to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close
of business on the relevant Record Dates according to their terms and the provisions of Section 307.

 

If any Bearer Security
surrendered for repayment shall not be accompanied by all appurtenant coupons maturing after the Repayment Date, such Security
may be paid after deducting from the amount payable therefor as provided in Section 1302 an amount equal to the face amount of
all such missing coupons, or the surrender of such missing coupon or coupons may be waived by the Company and the Trustee if there
be furnished to them such security or indemnity as they may require to save each of them and any Paying Agent harmless. If thereafter
the Holder of such Security shall surrender to the Trustee or any Paying Agent any such missing coupon in respect of which a deduction
shall have been made as provided in the preceding sentence, such Holder shall be entitled to receive the amount so deducted; provided,
however, that interest represented by coupons shall be payable only at an office or agency located outside the United States (except
as otherwise provided in Section 1002) and, unless otherwise specified as contemplated by Section 301, only upon presentation and
surrender of those coupons.

 

If the principal amount
of any Security surrendered for repayment shall not be so repaid upon surrender thereof, such principal amount (together with interest,
if any, thereon accrued to such Repayment Date) shall, until paid, bear interest from the Repayment Date at the rate of interest
or Yield to Maturity (in the case of Original Issue Discount Securities) set forth in such Security.

 

SECTION 1305. Securities
Repaid in Part. Upon surrender of any Registered Security which is to be repaid in part only, the Company shall execute
and the Trustee shall authenticate and deliver to the Holder of such Security, without service charge and at the expense of the
Company, a new Registered Security or Securities of the same series, of any authorized denomination specified by the Holder, in
an aggregate principal amount equal to and in exchange for the portion of the principal of such Security so surrendered which is
not to be repaid.

DEFEASANCE AND COVENANT DEFEASANCE

 

SECTION 1401. Applicability
of Article; Company’s Option to Effect Defeasance or Covenant Defeasance. If, pursuant to Section 301, provision
is made for either or both of (a) Defeasance of the Securities of or within a series under Section 1402 or (b) Covenant Defeasance
of the Securities of or within a series under Section 1403, then the provisions of such Section or Sections, as the case may be,
together with the other provisions of this Article (with such modifications thereto as may be specified pursuant to Section 301
with respect to any Securities), shall be applicable to such Securities and any coupons appertaining thereto, and the Company may
at its option by Board Resolution, at any time, with respect to such Securities and any coupons appertaining thereto, elect to
have Section 1402 (if applicable) or Section 1403 (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 1402. Defeasance
and Discharge. Upon the Company’s exercise of the above option applicable to this Section with respect to any Securities
of or within a series, the Company shall be deemed to have been discharged from its obligations with respect to such Outstanding
Securities and any coupons appertaining thereto on the date the conditions set forth in Section 1404 are satisfied (hereinafter,
“Defeasance”). For this purpose, such Defeasance means that the Company shall be deemed to have paid and discharged
the entire indebtedness represented by such Outstanding Securities and any coupons appertaining thereto, which shall thereafter
be deemed to be “Outstanding” only for the purposes of Section 1405 and the other Sections of this Indenture referred
to in clauses (A) and (B) below, and to have satisfied all of its other obligations under such Securities and any coupons appertaining
thereto and this Indenture insofar as such Securities and any coupons appertaining thereto are concerned (and the Trustee, at the
expense of the Company, shall execute proper instruments acknowledging the same), except for the following which shall survive
until otherwise terminated or discharged hereunder: (A) the rights of Holders of such Outstanding Securities and any coupons appertaining
thereto to receive, solely from the trust fund described in Section 1404 and as more fully set forth in such Section, payments
in respect of the principal of (and premium or Make-Whole Amount, if any) and interest, if any, on such Securities and any coupons
appertaining thereto when such payments are due, (B) the Company’s obligations with respect to such Securities under Sections
305, 306, 1002 and 1003 and to the extent provided with respect to the Securities of such series, Article 16, and the Company’s
obligations under Section 606 hereof (C) the rights, powers, trusts, duties and immunities of the Trustee hereunder and (D) this
Article. Subject to compliance with this Article Fourteen, the Company may exercise its option under this Section notwithstanding
the prior exercise of its option under Section 1403 with respect to such Securities and any coupons appertaining thereto.

 

SECTION 1403. Covenant
Defeasance. Upon the Company’s exercise of the above option applicable to this Section with respect to any Securities
of or within a series, the Company shall be released from its obligations under Sections 1004 to 1008, inclusive, and, if specified
pursuant to Section 301, its obligations under any other covenant contained herein or in any indenture supplemental hereto, with
respect to such Outstanding Securities and any coupons appertaining thereto on and after the date the conditions set forth in Section
1404 are satisfied (hereinafter, “Covenant Defeasance”), and such Securities and any coupons appertaining thereto shall
thereafter be deemed to be not “Outstanding” for the purposes of any direction, waiver, consent or declaration or Act
of Holders (and the consequences of any thereof) in connection with Sections 1004 to 1008, inclusive, or such other covenant, but
shall continue to be deemed “Outstanding” for all other purposes hereunder. For this purpose, such Covenant Defeasance
means that, with respect to such Outstanding Securities and any coupons appertaining thereto, the Company may omit to comply with
and shall have no liability in respect of any term, condition or limitation set forth in any such Section or such other covenant,
whether directly or indirectly, by reason of any reference elsewhere herein to any such Section or such other covenant or by reason
of reference in any such Section or such other covenant to any other provision herein or in any other document and such omission
to comply shall not constitute a default or an Event of Default under Section 501(4) or 501(8) or otherwise, as the case may be,
but, except as specified above, the remainder of this Indenture and such Securities and any coupons appertaining thereto shall
be unaffected thereby.

for the purpose of making the following payments, specifically pledged as security for, and dedicated solely to, the benefit of
the Holders of such Securities and any coupons appertaining thereto, (1) an amount in such currency, currencies or currency unit
in which such Securities and any coupons appertaining thereto are then specified as payable at Stated Maturity, or (2) Government
Obligations applicable to such Securities and coupons appertaining thereto (determined on the basis of the currency, currencies
or currency unit in which such Securities and coupons appertaining thereto are then specified as payable at Stated Maturity) which
through the scheduled payment of principal and interest in respect thereof in accordance with their terms will provide, not later
than the due date of any payment of principal of (and premium or Make-Whole Amount, if any) and interest, if any, on such Securities
and any coupons appertaining thereto, money in an amount, or (3) a combination thereof, in any case, in an amount, sufficient,
without consideration of any reinvestment of such principal and interest, in the opinion of a nationally recognized firm of independent
public accountants expressed in a written certification thereof delivered to the Trustee, to pay and discharge, and which shall
be applied by the Trustee (or other qualifying trustee) to pay and discharge, (i) the principal of (and premium or Make-Whole Amount,
if any) and interest, if any, 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.

501(6) and 501(7) are concerned, at any time during the period ending on the 91st day after the date of such deposit (it being
understood that this condition shall not be deemed satisfied until the expiration of such period).

the case of an election under Section 1402, the Company shall have delivered to the Trustee an Opinion of Counsel stating that
(i) the Company has received from, or there has been published by, the Internal Revenue Service a ruling, or (ii) since the date
of execution of this Indenture, there has been a change in the applicable Federal income tax law, in either case to the effect
that, and based thereon such opinion shall confirm that, the Holders of such Outstanding Securities and any coupons appertaining
thereto will not recognize income, gain or loss for Federal income tax purposes as a result of such Defeasance and will be subject
to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Defeasance
had not occurred.

 

(e) In
the case of an election under Section 1403, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect
that the Holders of such Outstanding Securities and any coupons appertaining thereto will not recognize income, gain or loss for
Federal income tax purposes as a result of such Covenant Defeasance and will be subject to Federal income tax on the same amounts,
in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred.

 

    61

Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions
precedent to the Defeasance under Section 1402 or the Covenant Defeasance under Section 1403 (as the case may be) have been complied
with and an Opinion of Counsel to the effect that either (i) as a result of a deposit pursuant to subsection (a) above and the
related exercise of the Company’s option under Section 1402 or Section 1403 (as the case may be), registration is not required
under the Investment Company Act of 1940, as amended, by the Company, with respect to the trust funds representing such deposit
or by the Trustee for such trust funds or (ii) all necessary registrations under said Act have been effected.

 

(g) Notwithstanding
any other provisions of this Section, such Defeasance or Covenant Defeasance shall be effected in compliance with any additional
or substitute terms, conditions or limitations which may be imposed on the Company in connection therewith pursuant to Section
301.

 

(h) The
payment of amounts payable to the Trustee pursuant to this Indenture shall be paid or provided for to the reasonable satisfaction
of the Trustee.

 

SECTION 1405. Deposited
Money and Government Obligations to Be Held in Trust; Other Miscellaneous Provisions. Subject to the provisions of the
last paragraph of Section 1003, all money and Government Obligations (or other property as may be provided pursuant to Section

coupons appertaining thereto shall be held in trust and applied by the Trustee, in accordance with the provisions of such Securities
and any coupons appertaining thereto and this Indenture, to the payment, either directly or through any Paying Agent (including
the Company acting as its own Paying Agent) as the Trustee may determine, to the Holders of such Securities and any coupons appertaining
thereto of all sums due and to become due thereon in respect of principal (and premium or Make-Whole Amount, if any) and interest,
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 301, if, after a deposit referred to in Section 1404(a) has been made, (a) the
Holder of a Security in respect of which such deposit was made is entitled to, and does, elect pursuant to Section 301 or the terms
of such Security to receive payment in a currency or currency unit other than that in which the deposit pursuant to Section 1404(a)
has been made in respect of such Security, or (b) a Conversion Event occurs in respect of the currency or currency unit in which
the deposit pursuant to Section 1404(a) has been made, the indebtedness represented by such Security and any coupons appertaining
thereto shall be deemed to have been, and will be, fully discharged and satisfied through the payment of the principal of (and
premium or Make-Whole Amount, if any), and interest, if any, on such Security as the same becomes due out of the proceeds yielded
by converting (from time to time as specified below in the case of any such election) the amount or other property deposited in

or Conversion Event based on the applicable market exchange rate for such currency or currency unit in effect on the second Business
Day prior to each payment date, except, with respect to a Conversion Event, for such currency or currency unit in effect (as nearly

Company Request any money or Government Obligations (or other property and any proceeds therefrom) held by it as provided in Section
1404 which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification
thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect a

any provisions of this Indenture, the Trustee may make such reasonable regulations as it may deem advisable for any meeting of

and in regard to the appointment and duties of inspectors of votes, the submission and examination of proxies, certificates and
other evidence of the right to vote, and such other matters concerning the conduct of the meeting as it shall deem appropriate.
Except as otherwise permitted or required by any such regulations, the holding of Securities shall be proved in the manner specified
in Section 104 and the appointment of any proxy shall be proved in the manner specified in Section 104 or by having the signature
of the Person executing the proxy witnessed or guaranteed by any trust company, bank or banker authorized by Section 104 to certify
to the holding of Bearer Securities. Such regulations may provide that written instruments appointing proxies, regular on their
face, may be presumed valid and genuine without the proof specified in Section 104 or other proof.

 

(b) The
Trustee shall, by an instrument in writing appoint a temporary chairman of the meeting, unless the meeting shall have been called
by the Company or by Holders of Securities as provided in Section 1502(b), in which case the Company or the Holders of Securities
of the series calling the meeting, as the case may be, shall in like manner appoint a temporary chairman. A permanent chairman
and a permanent secretary of the meeting shall be elected by vote of the Persons entitled to vote a majority in principal amount
of the Outstanding Securities of such series represented at the meeting.

 

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

meeting of Holders of Securities of any series duly called pursuant to Section 15.02 at which a quorum is present may be adjourned

or of their representatives by proxy and the principal amounts and serial numbers of the Outstanding Securities of such series
held or represented by them. The permanent chairman of the meeting shall appoint two inspectors of votes who shall count all votes
cast at the meeting for or against any resolution and who shall make and file with the secretary of the meeting their verified
written reports in duplicate of all votes cast at the meeting. A record, at least in duplicate, of the proceedings of each meeting
of Holders of Securities of any Series shall be prepared by the secretary of the meeting and there shall be attached to said record
the original reports of the inspectors of votes on any vote by ballot taken thereat and affidavits by one or more persons having
knowledge of the fact, setting forth a copy of the notice of the meeting and showing that said notice was given as provided in
Section 1502 and, if applicable, Section 1504. Each copy shall be signed and verified by the affidavits of the permanent chairman
and secretary of the meeting and one such copy shall be delivered to the Company and another to the Trustee to be preserved by
the Trustee, the latter to have attached thereto the ballots voted at the meeting. Any record so signed and verified shall be conclusive
evidence of the matters therein stated.

CONVERSION OF SECURITIES

 

SECTION 1601. Applicability
of Article; Conversion Privilege and Conversion Price. Securities of any series which are convertible shall be convertible
in accordance with their terms and (except as otherwise specified as contemplated by Section 301 for Securities of any series)
in accordance with this Article Sixteen. Subject to and upon compliance with the provisions of this Article Sixteen, at any time
during the period specified in the Securities, at the option of the Holder thereof, any Security or any portion of the principal
amount thereof which is $1,000 or an integral multiple of $1,000 may be converted at the principal amount thereof, or of such portion
thereof, into fully paid and nonassessable shares (calculated as to each conversion to the nearest 1/100 of a share) of Common
Stock of the Company, at the Conversion Price, determined as hereinafter provided, in effect at the time of conversion. In case
a Security or portion thereof is called for redemption, such conversion right in respect of the Security or portion so called shall
expire at the close of business on the Business Day immediately preceding the Redemption Date, unless the Company defaults in making
the payment due upon redemption, in which case such conversion right shall terminate on the date such default is cured.

 

The price at which
shares of Common Stock shall be delivered upon conversion (herein called the “Conversion Price”) of Securities of any
series shall be specified in such Securities. The Conversion Price shall be adjusted in certain instances as provided in Section
1604.

 

In case the Company
shall, by dividend or otherwise, declare or make a distribution on its Common Stock referred to in paragraph (4) of Section 1604,
the Holder of each Security, upon the conversion thereof pursuant to this Article Sixteen subsequent to the close of business on
the date fixed for the determination of stockholders entitled to receive such distribution and prior to the effectiveness of the
Conversion Price adjustment in respect of such distribution pursuant to paragraph (4) of Section 1604, shall be entitled to receive
for each share of Common Stock into which such Security is converted, the portion of the evidence of indebtedness, shares of Capital
Stock or assets so distributed applicable to one share of Common Stock; provided, however, that, at the election of the Company
(whose election shall be evidenced by a Board Resolution filed with the Trustee) with respect to all Holders so converting, the
Company may, in lieu of distributing to such Holder any portion of such distribution not consisting of cash or securities of the
Company, pay such Holder an amount in cash equal to the fair market value thereof (as determined in good faith by the Board of
Directors, whose determination shall be conclusive and described in a Board Resolution filed with the Trustee). If any conversion
of a Security entitled to the benefits described in the immediately preceding sentence occurs prior to the payment date for a distribution
to holders of Common Stock which the Holder of the Security so converted is entitled to receive in accordance with the immediately
preceding sentence, the Company may elect (such election to be evidenced by a Board Resolution filed with the Trustee) to distribute
to such Holder a due bill for the evidences of indebtedness, shares of Capital Stock or assets to which such Holder is so entitled,
provided that such due bill (i) meets any applicable requirements of the principal over-the-counter market or national securities
exchange or other market on which the Common Stock is then traded, and (ii) requires payment or delivery of such evidences of indebtedness
or assets no later than the date of payment or delivery thereof to holders of Common Stock receiving such distribution.

 

SECTION 1602. Exercise
of Conversion Privilege. In order to exercise the conversion privilege, the Holder of any Security to be converted shall
surrender such Security, duly endorsed or assigned to the Company or in blank, at any office or agency maintained by the Company
pursuant to Section 1002, accompanied by written notice to the Company at such office or agency that the Holder elects to convert
such Security or, if less than the entire principal amount thereof is to be converted, the portion thereof to be converted and
shall comply with any additional requirements set forth in such Security. Securities surrendered for conversion during the period
from the close of business on any Regular Record Date next preceding any Interest Payment Date to the opening of business on such
Interest Payment Date shall (except for Securities the Maturity of which is prior to such Interest Payment Date) be accompanied
by payment in funds acceptable to the Company of an amount equal to the interest payable on such Interest Payment Date on the principal
amount of Securities being surrendered for conversion and such interest shall be paid on such Interest Payment Date as provided
in Section 307. Except as provided in the preceding sentence, no payment or adjustment shall be made upon any conversion on account
of any interest accrued on the Securities surrendered for conversion or on account of any dividends on the Common Stock issued
upon conversion.

 

    66

     

    

 

The Company’s
delivery to the Holder of the fixed number of shares of the Common Stock of the Company (and any cash in lieu of any fractional
share of Common Stock) into which the Security is convertible shall be deemed to satisfy the Company’s obligation to pay
the principal amount of the Security and all accrued interest and original issue discount that has not previously been paid. The
shares of Common Stock of the Company so delivered shall be treated as issued first in payment of accrued interest and original
issue discount and then in payment of principal. Thus, accrued interest and original issue discount shall be treated as paid, rather
than canceled, extinguished or forfeited.

 

Securities shall be
deemed to have been converted immediately prior to the close of business on the day of surrender of such Securities for conversion
in accordance with the foregoing provisions, and at such time the rights of the Holders of such Securities as Holders shall cease,
and the Person or Persons entitled to receive the Common Stock issuable upon conversion shall be treated for all purposes as the
record holder or holders of such Common Stock at such time. As promptly as practicable on or after the conversion date, the Company
shall issue and shall deliver at such office or agency a certificate or certificates for the number of full shares of Common Stock
issuable upon conversion, together with payment in lieu of any fraction of a share, as provided in Section 1603.

 

In the case of any
Security which is converted in part only, as promptly as practicable on or after the conversion date the Company shall execute
and the Trustee shall authenticate and make available for delivery to the Holder thereof (or the Depositary in the case of a Global
Security), at the expense of the Company, a new Security or Securities, of authorized denominations in aggregate principal amount
equal to the unconverted portion of the principal amount of such Security.

 

SECTION 1603. Fractions
of Shares. No fractional shares of Common Stock shall be issued upon conversion of Securities. If more than one Security
shall be surrendered for conversion at one time by the same Holder, the number of full shares of Common Stock which shall be issuable
upon conversion thereof shall be computed on the basis of the aggregate principal amount of the Securities (or specified portions
thereof) so surrendered. Instead of any fractional share of Common Stock which would otherwise be issuable upon conversion of any
Security or Securities (or specified portions thereof), the Company shall pay a cash adjustment (rounded to the nearest cent) in
respect of such fraction in an amount equal to the same fraction of the Closing Price per share of the Common Stock on the day
of conversion (or, if such day is not a Trading Day, on the Trading Day immediately preceding such day).

 

SECTION 1604. Adjustment
of Conversion Price. The Conversion Price shall be subject to adjustment from time to time as follows:

 

(1) If
the Company pays or makes a dividend or other distribution (a) on its Common Stock exclusively in Common Stock or (b) on any other
class of Capital Stock of the Company, which dividend or distribution includes Common Stock of the Company, the Conversion Price
in effect at the opening of business on the day following the date fixed for the determination of stockholders entitled to receive
such dividend or other distribution (the “Dividend Record Date”) shall be reduced by multiplying such Conversion Price
by a fraction of which the numerator shall be the number of shares of Common Stock of the Company outstanding at the close of business
on the Dividend Record Date and the denominator shall be the sum of such number of shares and the total number of shares constituting
such dividend or other distribution. Such reduction shall become effective immediately after the opening of business on the day
following the date fixed for such determination. For the purposes of this paragraph (1), the number of shares of Common Stock of
the Company at any time outstanding shall not include shares held in the treasury of the Company, but shall include shares issuable
in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. The Company shall not pay any dividend
or make any distribution on shares of Common Stock held in the treasury of the Company.

 

    67

     

    

 

(2) Subject
to paragraph (6) of this Section, if the Company pays or makes a dividend or other distribution on its Common Stock consisting
exclusively of Short Term Rights (as defined below), or otherwise issues Short Term Rights to all holders of its Common Stock,
the Conversion Price in effect at the opening of business on the day following the record date for the determination of holders
of Common Stock entitled to receive such Short Term Rights (the “Rights Record Date”) shall be reduced by multiplying
such Conversion Price by a fraction of which the numerator shall be the number of shares of Common Stock of the Company outstanding
at the close of business on the Rights Record Date plus the number of shares of Common Stock of the Company which the aggregate
of the offering price of the total number of shares of Common Stock so offered for subscription or purchase would purchase at such
current market price and the denominator shall be the number of shares of Common Stock of the Company outstanding at the close
of business on the Rights Record Date plus the number of shares of Common Stock so offered for subscription or purchase. Such reduction
shall become effective immediately after the opening of business on the day following the Rights Record Date. For the purposes
of this paragraph (2), the number of shares of Common Stock of the Company at any time outstanding shall not include shares held
in the treasury of the Company, but shall include shares issuable in respect of scrip certificates issued in lieu of fractions
of shares of Common Stock of the Company. The Company shall not issue any rights, options or warrants in respect of shares of its
Common Stock held in the treasury of the Company. When used in this Section 1604, the term “Short Term Rights” shall
mean rights, warrants or options entitling the holders thereof (for a period commencing no earlier than the Rights Record Date
and expiring not more than 45 days after the Rights Record Date) to subscribe for or purchase shares of Common Stock of the Company
at a price per share less than the current market price per share (determined as provided in paragraph (7) of this Section 1604)
of the Common Stock of the Company on the Rights Record Date.

 

(3) In
case outstanding shares of Common Stock of the Company shall be subdivided into a greater number of shares of Common Stock, the
Conversion Price in effect at the opening of business on the day following the day upon which such subdivision becomes effective
shall be proportionately reduced, and, conversely, in case outstanding shares of Common Stock of the Company shall be combined
into a smaller number of shares of Common Stock, the Conversion Price in effect at the opening of business on the day following
the day upon which such combination becomes effective shall be proportionately increased, such reduction or increase, as the case
may be, to become effective immediately after the opening of business on the day following the day upon which such subdivision
or combination becomes effective.

 

(4) Subject
to the last sentence of this paragraph (4) of this Section, if the Company, by dividend or otherwise, (a) distributes to all holders
of its Common Stock evidences of its indebtedness, shares of any class of Capital Stock of the Company or other assets (other than
cash dividends out of current or retained earnings), or (b) distributes to substantially all holders of Common Stock rights or
warrants to subscribe for securities (other than Short Term Rights to which paragraph (2) of this Section 1604 applies), the Conversion
Price shall be reduced by multiplying such Conversion Price by a fraction of which the numerator shall be the current market price
per share (determined as provided in paragraph (7) of this Section 1604) of the Common Stock of the Company on the Reference Date
(as defined below) less the fair market value (as determined in good faith by the Board of Directors, whose determination shall
be conclusive and described in a Board Resolution filed with the Trustee), on the Reference Date, of the portion of the evidences
of indebtedness and other assets so distributed or of such subscription rights or warrants applicable to one share of Common Stock
(collectively, the “Market Value of the Distribution”) and the denominator shall be such current market price per share
of the Common Stock of the Company. Such reduction shall become effective immediately prior to the opening of business on the day
(the “Reference Date”) following the later of (a) the date fixed for the payment of such distribution and (b) the date
20 days after notice relating to such distribution is required to be given pursuant to Section 1606(a). If the Board of Directors
determines the fair market value of any distribution for purposes of this paragraph (4) by reference to the actual or when issued
trading market for any securities comprising such distribution, it must in doing so consider the prices in such market over the
same period used in computing the current market price per share pursuant to paragraph (7) of this Section 1604. In the event that,
with respect to any distribution to which this paragraph (4) of Section 1604 would otherwise apply, the Market Value of the Distribution
is greater than the current market price per share of the Common Stock (such distribution being referred to herein as an “Unadjusted
Distribution”), then the adjustment provided by this paragraph (4) shall not be made and in lieu thereof the provisions of
Section 1611 shall apply with respect to such Unadjusted Distribution.

 

    68

     

    

 

(5) The
Company may, but shall not be required to, make such reductions in the Conversion Price, in addition to those required by paragraphs
(1), (2), (3), and (4) of this Section 1604, as it considers to be advisable in order that any event treated for federal income
tax purposes as a dividend of stock or stock rights shall not be taxable to the recipients. In addition, the Company, from time
to time, may decrease the Conversion Price by any amount and for any reason, temporarily or otherwise, including situations where
the Board of Directors determines such decrease to be fair and appropriate with respect to transactions in which holders of Common
Stock have the right to participate.

 

(6) Rights
or warrants issued or distributed by the Company to all holders of its Common Stock entitling the holders thereof to subscribe
for or purchase shares of Common Stock or Preferred Stock, which rights or warrants (i) are deemed to be transferred with such
shares of Common Stock, (ii) are not exercisable and (iii) are also issued or distributed in respect of future issuances of Common
Stock, in each case in clauses (i) through (iii) until the occurrence of a specified event or events (“Trigger Events”),
shall for purposes of this Section 1604 not be deemed issued or distributed until the occurrence of the earliest Trigger Event.
Each share of Common Stock issued upon conversion of Securities pursuant to this Article Sixteen shall be entitled to receive the
appropriate number of Common Stock purchase rights (the “Rights”), if any, and the certificates representing the Common
Stock issued upon conversion shall bear such legends, if any. Notwithstanding anything to the contrary in this Article Sixteen,
there shall not be any adjustment to the Conversion Price as a result of (i) the distribution of separate certificates representing
the Rights; (ii) the occurrence of certain events entitling holders of Rights to receive, upon exercise thereof, Common Stock or
other securities of the Company or other securities of another corporation; or (iii) the exercise of such Rights. No adjustment
in the Conversion Price need be made for rights to purchase or the sale of Common Stock pursuant to a Company plan providing for
reinvestment of dividends or interest.

 

(7) For
the purpose of any computation under paragraph (2), (4) or (5) of this Section 1604, the “current market price” per
share of Common Stock of the Company on any date shall be deemed to be the average of the daily Closing Prices for the 15 consecutive
Trading Days selected by the Company commencing not more than 30 Trading Days before, and ending not later than, the date in question.

 

(8) No
adjustment in the Conversion Price shall be required unless such adjustment would require an increase or decrease of at least 1%
in the Conversion Price; provided, however, that any adjustments which by reason of this paragraph (8) are not required to be made
shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Article Sixteen shall
be made to the nearest cent or to the nearest one-hundredth of a share of Common Stock, as the case may be.

 

(9) Anything
herein to the contrary notwithstanding, in the event the Company shall declare any dividend or distribution requiring an adjustment
in the Conversion Price hereunder and shall, thereafter and before the payment of such dividend or distribution to stockholders,
legally abandon its plan to pay such dividend or distribution, the Conversion Price then in effect hereunder, if changed to reflect
such dividend or distribution, shall upon the legal abandonment of such plan be changed to the Conversion Price which would have
been in effect at the time of such abandonment (after giving effect to all other adjustments not so legally abandoned pursuant
to the provisions of this Article Sixteen) had such dividend or distribution never been declared.

 

    69

     

    

 

(10) Notwithstanding
any other provision of this Section 1604, no adjustment to the Conversion Price shall reduce the Conversion Price below the then
par value per share of the Common Stock of the Company, and any such purported adjustment shall instead reduce the Conversion Price
to such par value. Notwithstanding the foregoing sentence, the Company hereby covenants that it will from time to time take all
such action as may be required to assure that the par value per share of the Common Stock is at all times equal to or less than
the Conversion Price.

 

(11) In
the event that this Article Sixteen requires adjustments to the Conversion Price under more than one of paragraphs (1), (2), (3)
or (4) of this Section 1604, and the record or effective dates for the transaction giving rise to such adjustments shall occur
on the same date, then such adjustments shall be made by applying (to the extent they are applicable), first, the provisions of
paragraph (3) of this Section 1604, second, the provisions of paragraph (1) of this Section 1604, third, the provisions of paragraph
(4) of this Section 1604 and, fourth, the provisions of paragraph (2) of this Section 1604. Anything herein to the contrary notwithstanding,
no single event shall require or result in duplicative adjustments in the Conversion Price pursuant to this Section 1604. After
an adjustment to the Conversion Price under this Article Sixteen, any subsequent event requiring an adjustment under this Article
Sixteen shall cause an adjustment to the Conversion Price as so adjusted. If, after an adjustment, a Holder of a Security upon
conversion of such Security receives shares of two or more classes of Capital Stock of the Company, the Conversion Price shall
thereafter be subject to adjustment upon the occurrence of an action taken with respect to any such class of Capital Stock as is
contemplated by this Article Sixteen with respect to the Common Stock in this Article Sixteen.

 

SECTION 1605. Notice
of Adjustments of Conversion Price. Whenever the Conversion Price is adjusted as herein provided:

 

(1) the
Company shall compute the adjusted Conversion Price in accordance with Section 1604 or Section 1611 and shall prepare an Officer’s
Certificate setting forth the adjusted Conversion Price and showing in reasonable detail the facts upon which such adjustment is
based, and such certificate shall forthwith be filed (with a copy to the Trustee) at each office or agency maintained for the purpose
of conversion of any Securities pursuant to Section 1002; and

 

(2) a
notice stating that the Conversion Price has been adjusted and setting forth the adjusted Conversion Price shall forthwith be required,
and as soon as practicable after it is required, such notice shall be mailed by the Company to all Holders at their last addresses
as they shall appear in the Security Register.

 

SECTION 1606. Notice
of Certain Corporate Action. In case:

 

(1) the
Company shall take any action that would require a Conversion Price adjustment pursuant to Section 1604 or Section 1611; or

 

(2) there
shall occur any reclassification of the Common Stock of the Company (other than a subdivision or combination of its outstanding
shares of Common Stock), or any consolidation or merger to which the Company is a party, or the sale, transfer or lease of all
or substantially all of the assets of the Company and for which approval of any stockholders of the Company is required; or

 

(3) there
shall occur the voluntary or involuntary dissolution, liquidation or winding up of the Company, then the Company shall cause to
be filed at each office or agency maintained for the purpose of conversion of Securities pursuant to Section 1002, and shall cause
to be mailed to all Holders at their last addresses as they shall appear in the Security Register, at least 10 days prior to the
applicable record, effective or expiration date hereinafter specified, a notice stating (x) the date on which a record is to be
taken for the purpose of any dividend, distribution or granting of rights, warrants or options, or, if a record is not to be taken,
the date as of which the holders of Common Stock of record to be entitled to such dividend, distribution, rights, options or warrants
are to be determined, or (y) the date on which such reclassification, consolidation, merger, sale, transfer, dissolution, liquidation
or winding up is expected to become effective, and, if applicable, the date as of which it is expected that holders of Common Stock
of record shall be entitled to exchange their shares of Common Stock for securities, cash or other property deliverable upon such
reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding up.

 

    70

     

    

 

SECTION 1607. Company
to Reserve Common Stock. The Company shall at all times reserve and keep available, free from preemptive rights, out of
its authorized but unissued Common Stock, for the purpose of effecting the conversion of Securities, a number of shares of Common
Stock for the conversion of all outstanding Securities of any series which is convertible into Common Stock.

 

SECTION 1608. Taxes
on Conversion. The Company will pay any and all taxes that may be payable in respect of the issue or delivery of shares
of Common Stock on conversion of Securities pursuant hereto. The Company shall not, however, be required to pay any tax which may
be payable in respect of any transfer involved in the issue and delivery of shares of Common Stock in a name other than that of
the Holder of the Security or Securities to be converted, and no such issue or delivery shall be made unless and until the Person
requesting such issue has paid to the Company the amount of any such tax, or has established to the satisfaction of the Company
that such tax has been paid.

 

SECTION 1609. Covenants
as to Common Stock. The Company covenants that all shares of Common Stock which may be issued upon conversion of Securities
will upon issue be duly and validly issued, fully paid and nonassessable, free of preemptive or any similar rights, and, except
as provided in Section 1608, the Company will pay all taxes, liens and charges with respect to the issue thereof.

 

The Company will endeavor
promptly to comply with all Federal and state securities laws regulating the offer and delivery of shares of Common Stock upon
conversion of Securities, if any, and will list or cause to have quoted such shares of Common Stock on each national securities
exchange or in the over-the-counter market or such other market on which the Common Stock is then listed or quoted.

 

SECTION 1610. Cancellation
of Converted Securities. All Securities delivered for conversion shall be delivered to the Trustee to be cancelled by or
at the direction of the Trustee, which shall dispose of the same as provided in Section 309.

 

SECTION 1611. Provisions
in Case of Consolidation, Merger or Sale of Assets; Special Distributions. If any of the following shall occur, namely:
(i) any reclassification or change of outstanding shares of Common Stock issuable upon conversion of Securities (other than a change
in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination),
(ii) any consolidation or merger to which the Company is a party other than a merger in which the Company is the continuing corporation
and which does not result in any reclassification of, or change (other than a change in name, or par value, or from par value to
no par value, or from no par value to par value or as a result of a subdivision or combination) in, outstanding shares of Common
Stock or (iii) any sale or conveyance of all or substantially all of the property or business of the Company as an entirety, then
the Person formed by such consolidation or resulting from such merger or which acquires such properties or assets, as the case
may be, shall as a condition precedent to such transaction execute and deliver to the Trustee a supplemental indenture providing
that the Holder of each Security then outstanding shall have the right thereafter, during the period such Security shall be convertible
as specified in Section 1601, to convert such Security only into the kind and amount of securities, cash and other property receivable,
if any, upon such consolidation, merger, sale, transfer or lease by a holder of the number of shares of Common Stock of the Company
into which such Security might have been converted immediately prior to such consolidation, merger, sale, transfer or lease; provided
that the kind and amount of securities, cash and other property so receivable shall be determined on the basis of the following
assumptions. The holder of Common Stock referred to in the foregoing sentence:

 

    71

     

    

 

(1) is
not (a) a Person with which the Company consolidated, (b) a Person into which the Company merged or which merged into the Company,
or (c) a Person to which such sale, transfer or lease was made (any Person described in the foregoing clauses (a), (b), or (c),
hereinafter referred to as a “Constituent Person”), or (d) an Affiliate of a Constituent Person; and

 

(2) failed
to exercise his rights of election, if any, as to the kind or amount of securities, cash and other property receivable upon such
consolidation, merger, sale, transfer or lease (provided that if the kind or amount of securities, cash and other property receivable
upon such consolidation, merger, sale transfer or lease is not the same for each share of Common Stock of the Company in respect
of which such rights of election shall not have been exercised, then for the purpose of this Section 1611 the kind and amount of
securities, cash and other property receivable upon such consolidation, merger, sale, transfer or lease shall be deemed to be the
kind and amount so receivable per share by a plurality of such shares of Common Stock).

 

Such supplemental indenture
shall provide for adjustments which, for events subsequent to the effective date of such supplemental indenture, shall be as nearly
equivalent as may be practicable to the adjustments provided for in this Article Sixteen. If, in the case of any such consolidation,
merger, sale transfer or lease the stock or other securities and property (including cash) receivable thereupon by a holder of
Common Stock includes shares of stock or other securities and property of a corporation other than the successor or purchasing
corporation, as the case may be, in such consolidation, merger, sale, transfer or lease then such supplemental indenture shall
also be executed by such other corporation and shall contain such additional provisions to protect the interests of the Holders
of the Securities as the Board of Directors of the Company shall reasonably consider necessary by reason of the foregoing. The
above provisions of this Section 1611 shall similarly apply to successive consolidations, mergers, sales, transfers or leases.

 

In the event the Company
shall execute a supplemental indenture pursuant to this Section 1611, the Company shall promptly file with the Trustee an Officers’
Certificate briefly stating the reasons therefor, the kind or amount of shares of stock or securities or property (including cash)
receivable by Holders of the Securities upon the conversion of their Securities after any such reclassification, change, consolidation,
merger, sale, transfer or lease and any adjustment to be made with respect thereto.

 

If the Company makes
a distribution to all holders of its Common Stock that constitutes an Unadjusted Distribution pursuant to the last sentence of
paragraph (4) of Section 1604, then, from and after the record date for determining the holders of Common Stock entitled to receive
such distribution (the “Distribution Record Date”), a Holder of a Security who converts such Security in accordance
with the provisions of this Indenture shall, upon conversion, be entitled to receive, in addition to the shares of Common Stock
into which the Security is convertible, the kind and amount of evidences of indebtedness, shares of Capital Stock, or other assets
or subscription rights or warrants, as the case may be, comprising the distribution that such Holder would have received if such
Holder had converted the Security immediately prior to the Distribution Record Date.

 

    72

     

    

 

SECTION 1612. Trustee
Adjustment Disclaimer; Company Determination Final. The Trustee has no duty to determine when an adjustment under this
Article Sixteen should be made, how it should be made or what it should be. The Trustee has no duty to determine whether a supplemental
indenture under Section 1611 need be entered into or whether any provisions of any supplemental indenture are correct. The Trustee
shall not be accountable for and makes no representation as to the validity or value of any securities or assets issued upon conversion
of Securities. The Trustee shall not be responsible for the Company’s failure to comply with this Article Sixteen. Any determination
that the Company or the Board of Directors must make pursuant to this Article Sixteen is conclusive, absent manifest error.

 

SECTION 1613. When
No Adjustment Required. Except as expressly set forth in Section 1604, no adjustment in the Conversion Price shall be made
because the Company issues, in exchange for cash, property or services, shares of its Common Stock, or any securities convertible
into or exchangeable for shares of its Common Stock, or securities (including warrants, rights and options) carrying the right
to subscribe for or purchase shares of its Common Stock or such convertible or exchangeable securities.

 

In addition, notwithstanding
anything herein to the contrary, no adjustment in the Conversion Price shall be made pursuant to Section 1604 in respect of any
dividend or distribution if the Holders may participate therein (on a basis to be determined in good faith by the Board of Directors)
and receive the same consideration they would have received if they had converted the Securities immediately prior to the record
date with respect to such dividend or distribution.

 

SECTION 1614. Equivalent
Adjustments. In the event that, as a result of an adjustment made pursuant to Section 1604 above, the holder of any Security
thereafter surrendered for conversion shall become entitled to receive any shares of Capital Stock of the Company other than shares
of its Common Stock, thereafter the Conversion Price of such other shares so receivable upon conversion of any Securities shall
be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with
respect to Common Stock contained in this Article Sixteen.

[If the Holder of this
Security (as indicated below) is The Depository Trust Company (“DTC”) or a nominee of DTC, this Security is a Global
Security and the following two legends apply:

 

Unless this Security
is presented by an authorized representative of The Depository Trust Company a New York corporation (“DTC”) to the
Company or its agent for registration of transfer, conversion, exchange or payment, and such Security issued is registered in the
name of Cede & Co., or in such other name as requested by an authorized representative of DTC (and any payment is made to Cede
& Co. or to such other entity as is requested by an authorized representative of DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF
FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL, inasmuch as the registered owner hereof, Cede & Co., has an interest
herein.

 

Unless and until this
Security is exchanged in whole or in part for Securities in certificated form, this Security may not be transferred except as a
whole by DTC to a nominee thereof or by a nominee thereof to DTC or another nominee of DTC or by DTC or any such nominee to a successor
of DTC or a nominee of such successor.]

OPTIMIZERX CORPORATION,
a Nevada corporation (herein referred to as the “Company,” which term includes any successor corporation under the
Indenture referred to on the reverse hereof), for value received, hereby promises to pay to __________ or registered assigns the
principal sum of __________ Dollars on __________ (the “Stated Maturity Date”) [or insert date fixed for earlier redemption
(the “Redemption Date,” and together with the Stated Maturity Date with respect to principal repayable on such date,
the “Maturity Date.”)]

 

[If the Security is

Payment Date to which interest has been paid or duly provided for, semi-annually on __________ and __________ in each year (each,
an “Interest Payment Date”), commencing __________, at the rate of ____% per annum, until the principal hereof is paid
or duly provided for. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as
provided in such Indenture, be paid to the Holder in whose name this Security (or one or more Predecessor Securities) is registered
at the close of business on the Regular Record Date for such interest, which shall be the __________ or __________ (whether or
not a Business Day), as the case may be, next preceding such Interest Payment Date [at the office or agency of the Company maintained
for such purpose; provided, however, that such interest may be paid, at the Company’s option, by mailing a check to such
Holder at its registered address or by transfer of funds to an account maintained by such Holder within the United States]. Any
such interest not so punctually paid or duly provided for shall forthwith cease to be payable to the Holder on such Regular Record
Date, and may be paid to the Holder in whose name this Security (or one or more Predecessor Securities) is registered at the close
of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall
be given to Holders of Securities of this series not less than 10 days prior to such Special Record Date, or may be paid at any
time in any other lawful manner not inconsistent with the requirements of any over-the-counter market or securities exchange on
which the Securities of this series may be quoted or listed, and upon such notice as may be required by such market or exchange,
all as more fully provided in the Indenture. Interest will be computed on the basis of a 360-day year of twelve 30-day months.]
