SECTION
104.        Acts of Holders.


 


(a)          Any
request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken
by Holders of the Outstanding Securities of all series or one or more series, as the case may be, may be embodied in and evidenced
by one or more instruments of substantially similar tenor signed by such Holders in person or by agents duly appointed in writing.
If Securities of a series are issuable as Bearer Securities, any request, demand, authorization, direction, notice, consent, waiver
or other action provided by this Indenture to be given or taken by Holders of Securities of such series may, alternatively, be
embodied in and evidenced by the record of Holders of Securities of such series voting in favor thereof, either in person or by
proxies duly appointed in writing, at any meeting of Holders of Securities of such series duly called and held in accordance with
the provisions of Article Fifteen, or a combination of such instruments and any such record. Except as herein otherwise expressly
provided, such action shall become effective when such instrument or instruments or record or both are delivered to the Trustee
and, where it is hereby expressly required, to the Company. Such instrument or instruments and any such record (and the action
embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Holders signing such instrument
or instruments or so voting at any such meeting. Proof of execution of any such instrument or of a writing appointing any such
agent, or of the holding by any Person of a Security, shall be sufficient for any purpose of this Indenture and conclusive in favor
of the Trustee and the Company and any agent of the Trustee or the Company, if made in the manner provided in this Section. The
record of any meeting of Holders of Securities shall be proved in the manner provided in Section 1506.


 


(b)          The
fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying
that the individual signing such instrument or writing acknowledged to him the execution thereof. Where such execution is by a
signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient
proof of his authority. The fact and date of the execution of any such instrument or writing, or the authority of the Person executing
the same, may also be proved in any other reasonable manner which the Trustee deems sufficient.


 


(c)          The
ownership of Registered Securities shall be proved by the Security Register. 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,
but the Company shall have no obligation to do so. Notwithstanding TIA Section 316(c), such record date shall be the record date
specified in or pursuant to such Board Resolution, which shall be a date not earlier than the date 30 days prior to the first solicitation
of Holders generally in connection therewith and not later than the date such solicitation is completed. If such a record date
is fixed, such request, demand, authorization, direction, notice, consent, waiver or other Act may be given before or after such
record date, but only the Holders of record at the close of business on such record date shall be deemed to be Holders for the
purposes of determining whether Holders of the requisite proportion of Outstanding Securities have authorized or agreed or consented
to such request, demand, authorization, direction, notice, consent, waiver or other Act, and for that purpose the Outstanding Securities
shall be computed as of such record date; provided that no such authorization, agreement or consent by the Holders on such
record date shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later than
eleven months after the record date.


 


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


 


SECTION 105.        Notices,
etc., to Trustee and Company. Any request, demand, authorization, direction, notice, consent, waiver or Act of Holders or other
document provided or permitted by this Indenture to be made upon, given or furnished to, or filed with,


 


(1)         the

SECTION
106.        Notice to Holders; Waiver. Where this Indenture provides for notice
of any event to Holders of Registered Securities by the Company or the Trustee, such notice shall be sufficiently given (unless
otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to each such Holder affected by such
event, at his address as it appears in the Security Register, not later than the latest date, if any, and not earlier than the
earliest date, if any, prescribed for the giving of such notice. In any case where notice to Holders of Registered Securities is
given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall
affect the sufficiency of such notice with respect to other Holders of Registered Securities or the sufficiency of any notice to
Holders of Bearer Securities given as provided herein. Any notice mailed to a Holder in the manner herein prescribed shall be conclusively
deemed to have been received by such Holder, whether or not such Holder actually receives such notice.


 


If by reason of the suspension of or irregularities
in regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such notification
to Holders of Registered Securities as shall be made with the approval of the Trustee shall constitute a sufficient notification
to such Holders for every purpose hereunder.


 


Except as otherwise expressly provided herein
or otherwise specified with respect to any Securities pursuant to Section 301, where this Indenture provides for notice to Holders
of Bearer Securities of any event, such notice shall be sufficiently given if published in an Authorized Newspaper in The City
of New York and in such other city or cities as may be specified in such Securities on a Business Day, such 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, except that any published
notice may be in an official language of the country of publication.


 


Where this Indenture provides for notice
in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event,
and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such
filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

Date, Repayment Date, sinking fund payment date, Stated Maturity or Maturity of any Security or the last date on which a Holder

Security, shall be had, whether by levy or execution or otherwise, against the 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, nor shall any such parties be personally liable
for any such amounts, obligations or claims, or liable for any deficiency judgment 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 and that all such liability of and recourse
against such parties is expressly waived and released by the acceptance of the Securities by the Holders and as part of the consideration
for the issue of the Securities.

series and the Bearer Securities, if any, of each series and related coupons shall be substantially in the form of Exhibit A
hereto or in such other form as shall be established in one or more indentures supplemental hereto or approved from time to time
by or pursuant to a Board Resolution in accordance with Section 301, shall have such appropriate insertions, omissions, substitutions
and other variations as are required or permitted by this Indenture or any indenture supplemental hereto, and may have such letters,
numbers or other marks of identification or designation and such legends or endorsements placed thereon as the Company may deem
appropriate and as are not inconsistent with the provisions of this Indenture, or as may be required to comply with any law or
with any rule or regulation made pursuant thereto or with any rule or regulation of any over-the-counter market or securities exchange,
on which the Securities may be quoted or listed, or to conform to usage.


 


Unless otherwise specified as contemplated

The definitive Securities and coupons shall
be printed, lithographed or engraved or produced by any combination of these methods on a steel engraved border or steel engraved

202.        Form of Trustee’s Certificate of Authentication. Subject
to Section 611, the Trustee’s certificate of authentication shall be in substantially the following form:

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 (8) 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.


 




    	 	18	 



     


    

 


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.”

the form and/or terms of such certificates, documents or conditions;


 


(24)        Designation

and


 


(25)        Any
other terms of the series (which terms shall not be inconsistent with the provisions of this Indenture).


 


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 301. 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.


 




    	 	22	 



     


    

 


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


 


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


 




    	 	23	 



     


    

 


(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.

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 303. 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).


 




    	 	25	 



     


    

 


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.


 


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.


 




    	 	26	 



     


    

 


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.


 


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.


 




    	 	27	 



     


    

 


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.


 


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.


 




    	 	28	 



     


    

 


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.


 




    	 	29	 



     


    

 


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 or 1305 not involving any transfer.


 


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


 




    	 	30	 



     


    

 


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.


 


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.


 




    	 	31	 



     


    

 


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


 


SECTION
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:


 




    	 	32	 



     


    

 


(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.


 


(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.


 




    	 	33	 



     


    

 


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.


 


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).


 




    	 	34	 



     


    

 


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
Four - SATISFACTION AND DISCHARGE


 


SECTION 401.        Satisfaction
and Discharge of Indenture. This Indenture shall upon Company Request cease to be of further effect with respect to any 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


 


(A)         all
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,
whose surrender is not required or has been waived as provided in Section 305, (ii) Securities and coupons of such series which
have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 306, (iii) coupons appertaining
to Securities called for redemption and maturing after the relevant Redemption Date, whose surrender has been waived as provided
in Section 1106, and (iv) Securities and coupons of such series for whose payment money has theretofore been deposited in trust
or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust, as provided
in Section 1003) have been delivered to the Trustee for cancellation; or


 




    	 	35	 



     


    

 


(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


 


(i)          have
become due and payable, or


 


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


 


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


 


and the Company, in the case of (B)(i), (B)(ii) or (B)(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
precedent herein provided for relating to the satisfaction and discharge of this Indenture as to such series have been complied
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.

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


 




    	 	37	 



     


    

 


(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.


 




    	 	38	 



     


    

 


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,


 


(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.


 




    	 	39	 



     


    

 


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.


 


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.


 




    	 	40	 



     


    

 


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:


 


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 the Securities, 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;


 




    	 	41	 



     


    

 


(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.


 


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.


 




    	 	42	 



     


    

 


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.


 


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.


 




    	 	43	 



     


    

 


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).

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

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;


 




    	 	44	 



     


    

 


(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;


 


(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;

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;


 


(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

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.


 


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(7) or Section 501(8), 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.

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
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.


 


(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

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

by any Holder of a Security who has been a bona fide Holder of a Security for at least six months, or


 


(3)         the

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


 


(e)          If
the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any
cause with respect to the Securities of one or more series, the Company, by or pursuant to a Board Resolution, shall promptly appoint
a successor Trustee or 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.


 


(f)          The
Company shall give notice of each resignation and each removal of the Trustee with respect to the Securities of any series and
each appointment of a successor Trustee with respect to the Securities of any series in the manner provided for notices to the
Holders of Securities in Section 106. Each notice shall include the name of the successor Trustee with respect to the Securities
of such series and the address of its Corporate Trust Office.


 


SECTION
609.        Acceptance of Appointment by Successor.


 


(a)          In
case of the appointment hereunder of a successor Trustee with respect to all Securities, every such successor Trustee 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.


 




    	 	49	 



     


    

 


(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.


 


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.


 




    	 	50	 



     


    

 


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.


 




    	 	51	 



     


    

 


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.

such series:


 


(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.


 




    	 	52	 



     


    

 


(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;

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.

substantially all of its assets to, or merge with or into any other corporation, provided that in any such case, (1) either
the Company shall be the continuing corporation, or the successor corporation shall be a corporation organized and existing

available to the Trustee upon such default or may limit the right of the Holders of a majority in aggregate principal amount of

add to or change any of the provisions of this Indenture to provide that Bearer Securities may be registrable as to principal,
to change or eliminate any restrictions on the payment of principal of or premium or Make-Whole Amount, if any, or interest on

of the Holders of not less than a majority in principal amount of all Outstanding Securities affected by such supplemental indenture,
by Act of said Holders delivered to the Company and the Trustee, the Company, when authorized by or pursuant to a Board Resolution,
and the Trustee may enter into an indenture or indentures supplemental hereto for the purpose of adding any provisions to or changing
in any manner or eliminating any of the provisions of this Indenture or of modifying in any manner the rights of the Holders of

without the consent of the Holder of each Outstanding Security affected thereby:


 




    	 	57	 



     


    

 


(1)         change
the Stated Maturity of the principal of (or premium or Make-Whole Amount, if any, on) or any installment of principal of or interest
on, any Security; or reduce the principal amount thereof or the rate or amount of interest thereon, or any premium or Make-Whole
Amount payable upon the redemption thereof, or reduce the amount of the principal of an Original Issue Discount Security that would
be due and payable upon a declaration of acceleration of the Maturity thereof pursuant to Section 502 or the amount thereof provable
in bankruptcy pursuant to Section 504, or adversely affect any right of repayment at the option of the Holder of any Security,
or change any Place of Payment where, or the currency or currencies, currency unit or units or composite currency or currencies
in which, any Security or any premium or Make-Whole Amount or the interest thereon is payable, or impair the right to institute
suit for the enforcement of any such payment on or after the Stated Maturity thereof (or, in the case of redemption or repayment
at the option of the Holder, on or after the Redemption Date or the Repayment Date, as the case may be), or (if Securities of such
series are convertible) adversely affect the right of the Holder to convert any Security as provided in Article Seventeen, or modify
the provisions of this Indenture with respect to the subordination of the Securities in a manner materially adverse to the Holders;
or

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(11).


 


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.

indenture. If the Company shall so determine, new Securities of any series so modified as to conform, in the opinion of the Trustee

ARTICLE
Ten - 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.


 




    	 	59	 



     


    

 


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.


 




    	 	60	 



     


    

 


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


 




    	 	61	 



     


    

 


(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.


 


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
certificate 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.


 




    	 	62	 



     


    

 


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.


 


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.


 


ARTICLE
Eleven - REDEMPTION OF SECURITIES


 


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


 


SECTION
1102.        Election to Redeem; Notice to Trustee. The election of the Company
to redeem any Securities 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.


 




    	 	63	 



     


    

 


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.


 


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,


 




    	 	64	 



     


    

 


(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,


 


(10)        the
CUSIP number of such Security, if any, and


 


(11)        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.


 


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.


 




    	 	65	 



     


    

 


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.


 


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.

ARTICLE
Twelve - SINKING FUNDS


 


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


 


The minimum amount of any sinking fund payment
provided for by the terms of Securities of any series is herein referred to as a “mandatory sinking fund payment,”
and any payment in excess of such minimum amount provided for by the terms of such Securities of any series is herein referred
to as an “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.


 




    	 	67	 



     


    

 


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.


 


ARTICLE
Thirteen - REPAYMENT AT THE OPTION OF HOLDERS


 


SECTION
1301.        Applicability of Article. Repayment of Securities of any series
before their Stated Maturity at the option of Holders thereof shall be made in accordance with the terms of such Securities, if
any, and (except as otherwise specified by the terms of such series established pursuant to Section 301) in accordance with this
Article.


 


SECTION
1302.        Repayment of Securities. Securities of any series subject to
repayment in whole or in part at the option of the Holders thereof will, unless otherwise provided in the terms of such Securities,
be repaid at a price equal to the 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.


 




    	 	68	 



     


    

 


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.


 




    	 	69	 



     


    

 


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


 


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


 


ARTICLE

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

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 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 1009, 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 1009, inclusive, or such other covenant, but shall continue to be deemed “Outstanding” for all
other purposes hereunder. For this purpose, such Covenant Defeasance means that, with respect to such Outstanding Securities and
any coupons appertaining thereto, the Company may omit to comply with and shall have no liability in respect of any term, condition
or limitation set forth in any such Section 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.


 


SECTION
1404.        Conditions to Defeasance or Covenant Defeasance. The following

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

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).

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.

the case of an election under Section 1403, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect

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 301)

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

Security into the currency or currency unit in which such Security becomes payable as a result of such election or Conversion Event
based on the applicable market exchange rate for such currency or currency unit in effect on the second Business Day prior to each
payment date, except, with respect to a Conversion Event, for such currency or currency unit in effect (as nearly as feasible)

Trustee against any tax, fee or other charge imposed on or assessed against the Government Obligations deposited pursuant to Section
1404 or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for

in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered
to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect a Defeasance or Covenant
Defeasance, as applicable, in accordance with this Article.

direction, notice, consent, waiver or other action has been made, given or taken under this Indenture.

SECTION
1505.        Determination of Voting Rights; Conduct and Adjournment of Meetings.


 


(a)          Notwithstanding
any provisions of this Indenture, the Trustee may make such reasonable regulations as it may deem advisable for any meeting of
Holders of Securities of a series in regard to proof of the holding of Securities of such series and of the appointment of proxies
and in regard to the appointment and duties of inspectors of votes, the submission and examination of proxies, certificates and
other evidence of the right to vote, and such other matters concerning the conduct of the meeting as 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. The chairman of the meeting shall have no right to vote, except as a Holder of a Security of such series or
proxy.


 


(d)          Any
meeting of Holders of Securities of any series duly called pursuant to Section 1502 at which a quorum is present may be adjourned
from time to time by Persons entitled to vote a majority in principal amount of the Outstanding Securities of such series represented
at the meeting, and the meeting may be held as so adjourned without further notice.


 


SECTION
1506.        Counting Votes
and Recording Action of Meetings. The vote upon any resolution submitted to any meeting of Holders of Securities of any
series shall be by written ballots on which shall be subscribed the signatures of the Holders of Securities of such series or
of their representatives by proxy and the principal amounts and serial numbers of the Outstanding Securities of such series
held or represented by them. The permanent chairman of the meeting shall appoint two inspectors of votes who shall count all
votes cast at the meeting for or against any resolution and who shall make and file with the secretary of the meeting their
verified written reports in duplicate of all votes cast at the meeting. A record, at least in duplicate, of the proceedings
of each meeting of Holders of Securities of any Series shall be prepared by the secretary of the meeting and there shall be
attached to said record the original reports of the inspectors of votes on any vote by ballot taken thereat and affidavits by
one or more persons having knowledge of the 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.

ARTICLE
Sixteen - SUBORDINATION OF SECURITIES


 


SECTION
1601.        Agreement to Subordinate. Notwithstanding anything in this Indenture
to the contrary (other than Article Four of this Indenture), the Company covenants and agrees, and each Holder of a Security,
by his acceptance thereof, likewise covenants and agrees, that, to the extent and in the manner hereinafter set forth in this Article,
the Indebtedness represented by the Securities and the payment of any Obligations with respect to each and all of the Securities
are hereby expressly made subordinate and subject in right of payment to the prior payment in full of all Senior Indebtedness.


 


SECTION
1602.        Payment Over of Proceeds upon Dissolution, Etc. In the event
of (a) any insolvency or bankruptcy case or Proceeding, or any receivership, liquidation, reorganization or other similar case
or Proceeding in connection therewith, relative to the Company or to its creditors, as such, or to its assets, or (b) any
liquidation, dissolution or other winding up of the Company, whether voluntary or involuntary and whether or not involving insolvency
or bankruptcy, or (c) any assignment for the benefit of creditors or any other marshaling of assets and liabilities of the
Company, then and in any such event specified in (a), (b) or (c) above (each such event, if any, herein sometimes referred to as
a “Proceeding”)


 


(1)         the
holders of Senior Indebtedness shall first be entitled to receive payment in full of all Obligations due or to become due on or
in respect of all Senior Indebtedness, or provision shall be made for such payment in cash or cash equivalents or otherwise in
a manner satisfactory to the holders of Senior Indebtedness, before the Holders of the Securities are entitled to receive any payment
or distribution on account of principal of or premium, if any, or interest on or other Obligations in respect of the Securities
or on account of any purchase, redemption or other acquisition of Securities by the Company or any Subsidiary (individually and
collectively, a “Securities Payment”), and


 


(2)         any
payment or distribution of assets of the Company of any kind or character, whether in cash, property or securities (other than
Capital Stock or securities of the Company as reorganized or readjusted, or securities of the Company or any other corporation
provided for by a plan of reorganization or readjustment, the payment of which is subordinate, at least to the extent provided
in this Article Sixteen with respect to the Securities, to the payment in full, without diminution or modification by such
plan, of all Senior Indebtedness), to which the Holders would be entitled except for the provisions of this Article Sixteen,
shall be paid by the liquidating trustee or agent or other person making such a payment or distribution, directly to the holders
of Senior Indebtedness) (or their representative(s) or trustee(s) acting on their behalf), ratably according to the aggregate amounts
remaining unpaid on account of the principal of or interest on and other amounts due on the Senior Indebtedness held or represented
by each, to the extent necessary to make payment in full of all Senior Indebtedness remaining unpaid, after giving effect to any
concurrent payment or distribution to the holders of such Senior Indebtedness.


 




    	 	77	 



     


    

 


In the event that, notwithstanding the foregoing
provisions of this Section 1602, the Trustee or the Holder of any Security shall have received any payment or distribution
of assets of the Company of any kind or character, whether in cash, property or securities (other than Capital Stock or securities
of the Company as reorganized or readjusted, or securities of the Company or any other corporation provided for by a plan of reorganization
or readjustment, the payment of which is subordinate, at least to the extent provided in this Article with respect to the Securities,
to the payment in full, without diminution or modification by such plan, of Senior Indebtedness), before all Senior Indebtedness
is paid in full or payment thereof provided for in cash or cash equivalents or otherwise in a manner satisfactory to the holders
of Senior Indebtedness, such payment or distribution shall be held in trust for the benefit of, and be paid over to, the holders
of the Senior Indebtedness remaining unpaid (or their representative(s) or trustee(s) acting on their behalf), ratably as aforesaid,
for application to the payment of such Senior Indebtedness until such Senior Indebtedness shall have been paid in full, after giving
effect to any concurrent payment or distribution to the holders of such Senior Indebtedness.


 


The consolidation of the Company with, or
the merger of the Company into, another Person or the liquidation or dissolution of the Company following the conveyance or transfer
of all or substantially all of its properties and assets as an entirety to another Person upon the terms and conditions set forth
in Article Eight shall not be deemed a Proceeding for the purposes of this Section 1602 if the Person formed by such consolidation
or into which the Company is merged or the Person which acquires by conveyance or transfer such properties and assets as an entirety,
as the case may be, shall, as a part of such consolidation, merger, conveyance or transfer, comply with the conditions set forth
in Article Eight.


 


SECTION
1603.        No Payment When Senior Indebtedness in Default. Anything in this
Indenture to the contrary notwithstanding, no payment on account of principal of or redemption of, interest on or other amounts
due on the Securities, and no redemption, purchase, or other acquisition of the Securities, shall be made by or on behalf of the
Company (i) unless full payment of amounts then due for principal and interest and of all other obligations then due on all Senior
Indebtedness has been made or duly provided for pursuant to the terms of the instrument governing such Senior Indebtedness, (ii)
if, at the time of such payment, redemption, purchase or other acquisition, or immediately after giving effect thereto, there shall
exist under any Senior Indebtedness, or any agreement pursuant to which any Senior Indebtedness is issued, any default, which default
shall not have been cured or waived and which default shall have resulted in the full amount of such Senior Indebtedness being
declared due and payable or (iii) if, at the time of such payment, redemption, purchase or other acquisition, the Trustee shall
have received written notice from the holder or holders of any Senior Indebtedness or their representative or representatives (a
“Payment Blockage Notice”) that there exists under such Senior Indebtedness, or any agreement pursuant to which such
Senior Indebtedness is issued, any default, which default shall not have been cured or waived, permitting the holders thereof to
declare the full amount of such Senior Indebtedness due and payable, but only for the period (the “Payment Blockage Period”)
commencing on the date of receipt of the Payment Blockage Notice and ending (unless earlier terminated by notice given to the Trustee
by the Holders of such Senior Indebtedness) on the earlier of (A) the date on which such event of default shall have been cured
or waived or (B) 180 days from the receipt of the Payment Blockage Notice. Upon termination of a Payment Blockage Period, payments
on account of principal of or interest on the Securities and redemptions, purchases or other acquisitions may be made by or on
behalf of the Company. Notwithstanding anything herein to the contrary, (A) only one Payment Blockage Notice may be given during
any period of 360 consecutive days with respect to the same event of default and any other events of default on the same issue
of Senior Indebtedness existing and known to the person giving such notice at the time of such notice and (B) no new Payment Blockage
Period may be commenced by the holder or holders of the same issue of Senior Indebtedness or their representative or representatives
during any period of 360 consecutive days unless all events of default which were the object of the immediately preceding Payment
Blockage Notice, and any other event of default on the same issue of Senior Indebtedness existing and known to the person giving
such notice at the time of such notice, have been cured or waived.


 




    	 	78	 



     


    

 


In the event that, notwithstanding the provisions
of this Section 1603, payments are made by or on behalf of the Company in contravention of the provisions of this Section 1603,
such payments shall be held by the Trustee, any Paying Agent or the Holders, as applicable, in trust for the benefit of, and shall
be paid over to and delivered to, the holders of Senior Indebtedness or their representative or the trustee under the indenture
or other agreement (if any), pursuant to which any instruments evidencing any Senior Indebtedness may have been issued, as their
respective interests may appear, for application to the payment of all Senior Indebtedness remaining unpaid to the extent necessary
to pay all Senior Indebtedness in full in accordance with the terms of such Senior Indebtedness, after giving effect to any concurrent
payment or distribution to or for the holders of Senior Indebtedness.


 


The provisions of this Section shall not
apply to any payment with respect to which Section 1602 would be applicable.


 


SECTION
1604.        Reliance by Senior Indebtedness on Subordination Provisions.
Each Holder of any Security by his acceptance thereof acknowledges and agrees that the foregoing subordination provisions are,
and are intended to be, an inducement and a consideration for each holder of any Senior Indebtedness, whether such Senior Indebtedness
was created or acquired before or after the issuance of the Securities, to acquire and continue to hold, or to continue to hold,
such Senior Indebtedness, and such holder of Senior Indebtedness shall be deemed conclusively to have relied on such subordination
provisions in acquiring and continuing to hold or in continuing to hold such Senior Indebtedness.


 




    	 	79	 



     


    

 


SECTION
1605.        Subrogation to Rights of Holders of Senior Indebtedness. Subject
to the payment in full of all Obligations due or to become due on or in respect of Senior Indebtedness, or the provision for such
payment in cash or cash equivalents or otherwise in a manner satisfactory to the holders of Senior Indebtedness, the Holders of
the Securities shall be subrogated to the extent of the payments or distributions made to the holders of such Senior Indebtedness
pursuant to the provisions of this Article Sixteen to the rights of the holders of such Senior Indebtedness to receive payments
and distributions of cash, property and securities applicable to the Senior Indebtedness until the principal of and premium, if
any, and interest on the Securities shall be paid in full. For purposes of such subrogation, no payments or distributions to the
holders of the Senior Indebtedness of any cash, property or securities to which the Holders of the Securities or the Trustee would
be entitled except for the provisions of this Article Sixteen, and no payments over pursuant to the provisions of this Article Sixteen
to the holders of Senior Indebtedness by Holders of the Securities or the Trustee, shall, as among the Company, its creditors other
than holders of Senior Indebtedness and the Holders of the Securities, be deemed to be a payment or distribution by the Company
to or on account of the Senior Indebtedness.


 


SECTION
1606.        Provisions Solely to Define Relative Rights. The provisions of
this Article Sixteen are and are intended solely for the purpose of defining the relative rights of the Holders of the Securities
on the one hand and the holders of Senior Indebtedness on the other hand. Nothing contained in this Article or elsewhere in this
Indenture or in the Securities is intended to or shall (a) impair, as among the Company, its creditors other than holders
of Senior Indebtedness and the Holders of the Securities, the obligation of the Company, which is absolute and unconditional (and
which, subject to the rights under this Article Sixteen of the holders of Senior Indebtedness, is intended to rank equally
with all other general obligations of the Company), to pay to the Holders of the Securities the principal of and premium, if any,
and interest on the Securities as and when the same shall become due and payable in accordance with their terms; or (b) affect
the relative rights against the Company of the Holders of the Securities and creditors of the Company other than the holders of
Senior Indebtedness; or (c) prevent the Trustee or the Holder of any Security from exercising all remedies otherwise permitted
by applicable law upon default under this Indenture, subject to the rights, if any, under this Article of the holders of Senior
Indebtedness to receive cash, property and securities otherwise payable or deliverable to the Trustee or such Holder.


 


SECTION
1607.        Trustee to Effectuate Subordination. Each Holder of a Security
by his acceptance thereof authorizes and directs the Trustee on his behalf to take such action as may be necessary or appropriate
to effectuate, as between the Holders of the Securities and the holders of Senior Indebtedness, the subordination provided in this
Article Sixteen and appoints the Trustee his attorney-in-fact for any and all such purposes, including, in the event of any
dissolution, winding up or liquidation or reorganization under any applicable bankruptcy law of the Company (whether in bankruptcy,
insolvency or receivership Proceedings or otherwise), the timely filing of a claim for the unpaid balance of such Holder’s
Securities in the form required in such Proceedings and the causing of such claim to be approved. If the Trustee does not file
a claim or proof of debt in the form required in such Proceedings prior to 30 days before the expiration of the time to file such
claims or proofs, then the holders of Senior Indebtedness, jointly, or their representatives shall have the right to file an appropriate
claim for and on behalf of the Holders and to demand, sue for, collect, receive and receipt for the payments and distributions
in respect of the Securities which are required to be paid or delivered to the holders of Senior Indebtedness as provided in this
Article Sixteen and to take all such other action in the name of the Holders or otherwise, as such holder of Senior Indebtedness
or representative thereof may determine to be necessary or appropriate for the enforcement of the provisions of this Article Sixteen.


 




    	 	80	 



     


    

 


SECTION
1608.        No Waiver of Subordination Provisions. No right of any present
or future holder of any Senior Indebtedness to enforce subordination as herein provided shall at any time in any way be prejudiced
or impaired by any act or failure to act on the part of the Company or by any act or failure to act, in good faith, by any such
holder or any representative or trustee therefor, or by any non-compliance by the Company with the terms, provisions and covenants
of this Indenture, regardless of any knowledge thereof any such holder may have or be otherwise charged with.


 


Without in any way limiting the generality
of the foregoing paragraph, the holders of Senior Indebtedness may, at any time from time to time, without the consent of or notice
to the Trustee or the Holders of the Securities, without incurring responsibility to the Holders of the Securities and without
impairing or releasing the subordination provided in this Article Sixteen or the obligations hereunder of the Holders of the
Securities to the holders of Senior Indebtedness, do any one or more of the following: (i) change the manner, place or terms
of payment or extend the time of payment of, or renew or alter, Senior Indebtedness, or otherwise amend or supplement in any manner
Senior Indebtedness or any instrument evidencing the same or any agreement under which Senior Indebtedness is outstanding; (ii) sell,
exchange, release or otherwise deal with any property pledged, mortgaged or otherwise securing Senior Indebtedness; (iii) release
any Person liable in any manner for the collection of Senior Indebtedness and settle or compromise Senior Indebtedness (which,
to the extent so settled and compromised, shall be deemed to have been paid in full for all purposes hereof); (iv) apply any
amounts received to any liability of the Company owing to holders of Senior Indebtedness; and (v) exercise or refrain from
exercising any rights against the Company and any other Person.


 


SECTION
1609.        Notice to Trustee. The Company shall give prompt written notice
to the Trustee of any default or event of default with respect to any Senior Indebtedness or of any fact known to the Company which
would prohibit the making of any payment to or by the Trustee in respect of the Securities pursuant to the provisions of this Article Sixteen.
Notwithstanding the provisions of this Article Sixteen or any other provision of this Indenture, the Trustee shall not be
charged with knowledge of the existence of any facts which would prohibit the making of any payment to or by the Trustee in respect
of the Securities, unless and until the Trustee shall have received written notice thereof from the Company or a holder of Senior
Indebtedness or from any representative or trustee acting on their behalf; and, prior to the receipt of any such written notice,
the Trustee, subject to the provisions of Section 612, shall be entitled in all respects to assume that no such facts exist; provided,
however, that if the Trustee shall not have received the notice provided for in this Section at least three Business Days
prior to the date upon which by the terms hereof any money may become payable for any purpose (including, without limitation, the
payment of the principal of and premium, if any, or interest on any Security), then, anything herein contained to the contrary
notwithstanding, the Trustee shall have full power and authority to receive such money and to apply the same to the purpose for
which such money was received and shall not be affected by any notice to the contrary which may be received by it within three
Business Days prior to such date. Nothing contained in this Article Sixteen or any other Article of this Indenture or in any of
the Securities shall prevent (a) the Company, at any time except during the pendency of any Proceeding, or under the conditions
described in Section 1603, from making payments at any time in respect of the Securities, or (b) the application by the Trustee
of any money deposited with it hereunder to the payment of or on account of the Securities, or the retention thereof by any Holder,
if the Trustee did not have notice, as provided in this Section 1609, that such payment would have been prohibited by the
provisions of this Article Sixteen.


 




    	 	81	 



     


    

 


Subject to the provisions of Section 612,
the Trustee shall be entitled to rely on the delivery to it of a written notice by a Person representing himself to be a holder
of Senior Indebtedness (or a representative or trustee therefor) to establish that such notice has been given by a holder of Senior
Indebtedness (or a trustee therefor). In the event that the Trustee determines in good faith that further evidence is required
with respect to the right of any Person as a holder of Senior Indebtedness to participate in any payment or distribution pursuant
to this Article Sixteen, the Trustee may request such Person to furnish evidence to the reasonable satisfaction of the Trustee
as to the amount of Senior Indebtedness held by such Person, the extent to which such Person is entitled to participate in such
payment or distribution and any other facts pertinent to the rights of such Person under this Article Sixteen, and if such
evidence is not furnished, the Trustee may defer any payment to such Person pending judicial determination as to the right of such
Person to receive such payment.


 


SECTION
1610.        Reliance on Judicial Order or Certificate of Liquidating Agent.
Upon any payment or distribution of assets of the Company referred to in this Article Sixteen, the Trustee, subject to the
provisions of Section 612, and the Holders of the Securities shall be entitled to rely upon any order or decree entered by any
court of competent jurisdiction in which any Proceeding is pending, or a certificate of the trustee in bankruptcy, receiver, liquidating
trustee, custodian, assignee for the benefit of creditors, agent or other Person making such payment or distribution, delivered
to the Trustee or to the Holders of Securities, for the purpose of ascertaining the Persons entitled to participate in such payment
or distribution, the holders of the Senior Indebtedness and other indebtedness of the Company, the amount thereof or payable thereon,
the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article.


 


SECTION
1611.        Trustee Not Fiduciary for Holders of Senior Indebtedness. The
Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Indebtedness. Nothing contained in this Article Sixteen
or elsewhere in this Indenture, or in any of the Securities, shall prevent the application by the Trustee of any moneys which were
deposited with it hereunder, prior to its receipt of written notice of facts which would prohibit such application, for the purpose
of the payment of or on account of the principal of or interest on, the Securities unless, prior to the date on which such application
is made by the Trustee, the Trustee shall be charged with notice under Section 1609 hereof of the facts which would prohibit
the making of such application.


 


SECTION
1612.        Rights of Trustee as Holder of Senior Indebtedness; Preservation
of Trustee’s Rights. The Trustee in its individual capacity shall be entitled to all the rights set forth in this Article Sixteen
with respect to any Senior Indebtedness which may at any time be held by it, to the same extent as any other holder of Senior Indebtedness,
and nothing in this Indenture shall deprive the Trustee of any of its rights as such holder. Nothing in this Article shall apply
to claims of, or payments to, the Trustee under or pursuant to Section 606.


 




    	 	82	 



     


    

 


SECTION
1613.        Article Applicable to Paying Agents. In case at any time any
Paying Agent other than the Trustee shall have been appointed by the Company and be then acting hereunder, the term “Trustee”
as used in this Article Sixteen shall in such case (unless the context otherwise requires) be construed as extending to and
including such Paying Agent within its meaning as fully for all intents and purposes as if such Paying Agent were named in this
Article in addition to or in place of the Trustee; provided, however, that Section 1612 shall not apply to the Company
or any Affiliate of the Company if it or such Affiliate acts as Paying Agent.


 


ARTICLE
Seventeen - CONVERSION OF SECURITIES


 


SECTION
1701.        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 Seventeen. Subject to and upon compliance
with the provisions of this Article Seventeen, 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 1704.


 


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 1704, the Holder of each
Security, upon the conversion thereof pursuant to this Article Seventeen 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 1704, 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.


 




    	 	83	 



     


    

 


SECTION
1702.        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.


 


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 1703.


 




    	 	84	 



     


    

 


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
1703.        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
1704.        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.


 


(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 1704, 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 1704)
of the Common Stock of the Company on the Rights Record Date.


 




    	 	85	 



     


    

 


(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 1704
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 1704) 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 1706(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 1704. In the event that, with respect to any distribution to which this paragraph (4) of Section 1704
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 1711 shall apply with respect to such Unadjusted
Distribution.


 




    	 	86	 



     


    

 


(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 1704, 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 1704 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 Seventeen 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
Seventeen, 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 1704, 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.


 




    	 	87	 



     


    

 


(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 Seventeen
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 Seventeen) had such dividend or distribution never been declared.


 


(10)        Notwithstanding
any other provision of this Section 1704, 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 Seventeen requires adjustments to the Conversion Price under more than one of paragraphs (1),
(2), (3) or (4) of this Section 1704, 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 1704, second, the provisions of paragraph (1) of this Section 1704, third,
the provisions of paragraph (4) of this Section 1704 and, fourth, the provisions of paragraph (2) of this Section 1704.
Anything herein to the contrary notwithstanding, no single event shall require or result in duplicative adjustments in the Conversion
Price pursuant to this Section 1704. After an adjustment to the Conversion Price under this Article Seventeen, any subsequent
event requiring an adjustment under this Article Seventeen 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 Seventeen with respect to the Common Stock in this
Article Seventeen.


 




    	 	88	 



     


    

 


SECTION
1705.        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 1704 or Section 1711 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
1706.        Notice of Certain Corporate Action. In case:


 


(1)         the
Company shall take any action that would require a Conversion Price adjustment pursuant to Section 1704 or Section 1711; 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.


 


SECTION
1707.        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.


 




    	 	89	 



     


    

 


SECTION
1708.        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
1709.        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 1708, 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
1710.        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
1711.        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 1701, 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:


 




    	 	90	 



     


    

 


(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 1711 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 Seventeen. 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 1711 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 1711, 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
1704, 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.


 




    	 	91	 



     


    

 


SECTION
1712.        Trustee Adjustment Disclaimer; Company Determination Final. The
Trustee has no duty to determine when an adjustment under this Article Seventeen 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 1711 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 Seventeen. Any determination that the Company or the Board of Directors
must make pursuant to this Article Seventeen is conclusive, absent manifest error.


 


SECTION
1713.        When No Adjustment Required. Except as expressly set forth in
Section 1704, 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.


 


(1)         Notwithstanding
anything herein to the contrary, no adjustment in the Conversion Price shall be made pursuant to Section 1704 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
1714.        Equivalent Adjustments. In the event that, as a result of an
adjustment made pursuant to Section 1704 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 Seventeen.

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,

ASSEMBLY BIOSCIENCES, INC., a Delaware 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 to bear interest prior to Maturity, insert
— and to pay interest thereon from __________ or from the most recent Interest 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.]


 


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


 


The principal of this Security payable on the Stated Maturity
Date [or the principal of, premium or Make-Whole Amount, if any, and, if the Redemption Date is not an Interest Payment Date, interest
on this Security payable on the Redemption Date] will be paid against presentation of this Security at the office or agency of
the Company maintained for that purpose in __________, in such coin or currency of the United States of America as at the time
of payment is legal tender for the payment of public and private debts.


 




    	 	A-2	 



     


    

 


Interest payable on this Security on any Interest Payment Date
and on the [Stated] Maturity Date [or Redemption Date, as the case may be,] will include interest accrued from and including the
next preceding Interest Payment Date in respect of which interest has been paid or duly provided for (or from and including __________,
if no interest has been paid on this Security) to but excluding such Interest Payment Date or the [Stated] Maturity Date [or Redemption
Date, as the case may be.] If any Interest Payment Date or the [Stated] Maturity Date or [Redemption Date] falls on a day that
is not a Business Day, as defined below, principal, premium or Make-Whole Amount, if any, and/or interest payable with respect
to such Interest Payment Date or [Stated] Maturity Date [or Redemption Date, as the case may be,] will be paid on the next succeeding
Business Day with the same force and effect as if it were paid on the date such payment was due, and no interest shall accrue on
the amount so payable for the period from and after such Interest Payment Date or [Stated] Maturity Date [or Redemption Date, as
the case may be.] “Business Day” means any day, other than a Saturday or Sunday, that is neither a legal holiday nor
a day on which banking institutions in The City of New York are required or authorized by law, regulation or executive order to

payments of principal, premium or Make-Whole Amount, if any, and interest in respect of this Security will be made by the Company

the same.

or other governmental charge payable in connection therewith,

for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose

or penalty or otherwise, all such liability being, by the acceptance hereof and as part of the consideration for the issue hereof,
expressly waived and released.
