pledgee’s right so to act with respect to such Securities and that the pledgee is not the Company or any other obligor upon the
Securities or any Affiliate of the Company or of such other obligor. In case of a dispute as to such right, the advice of counsel shall
be full protection in respect of any decision made by the Trustee in accordance with such advice.

Where any Person is required to make, give or execute two or more applications,
requests, consents, certificates, statements, opinions or other instruments under this Indenture, they may, but need not, be consolidated
and form one instrument.


 


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 calendar 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.


 






    10


    


    

 


(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 Trustee by any Holder or by the Company shall
be sufficient for every purpose hereunder if made, given, furnished or filed in writing to or with the Trustee at [_________________________]
or at any other address previously furnished in writing to the Company by the Trustee, Attention: [__________]; or


 


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


 


(3) either the Trustee or the Company, by the other
party or by any Holder, shall be sufficient for every purpose hereunder if given by facsimile transmission, receipt confirmed by telephone
followed by an original copy delivered by guaranteed overnight courier; if to the Trustee at facsimile number [__________]; and if to
the Company at facsimile number [__________].


 


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.


 






    11


    


    

 


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


 


Any request, demand, authorization, direction, notice, consent or waiver
required or permitted under this Indenture shall be in the English language, except that any published notice may be in an official language
of the country of publication.


 


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


 


SECTION 107. Counterparts; Effect of Headings and Table of
Contents . This Indenture may be executed in any number of counterparts, each of which so executed shall be deemed to be an original,
but all such counterparts shall together constitute but one and the same Indenture. The Article and Section headings herein
and the Table of Contents are for convenience only and shall not affect the construction hereof.


 


SECTION 108. Successors and Assigns . All covenants and
agreements in this Indenture by the Company shall bind its successors and assigns, whether so expressed or not.


 


SECTION 109. Severability Clause . In case any provision
in this Indenture or in any Security or coupon shall be held invalid, illegal or unenforceable, the validity, legality and enforceability
of the remaining provisions shall not in any way be affected or impaired thereby.


 


SECTION 110. Benefits of Indenture . Nothing in this Indenture
or in the Securities or coupons, if any, express or implied, shall give to any Person, other than the parties hereto, any Security Registrar,
any Paying Agent, any Authenticating Agent and their successors hereunder and the Holders any benefit or any legal or equitable right,
remedy or claim under this Indenture.


 


SECTION 111. Governing Law . This Indenture and the Securities
and coupons shall be governed by and construed in accordance with the laws of the State of New York. This Indenture is subject to the
provisions of the TIA that are required to be part of this Indenture and shall, to the extent applicable, be governed by such provisions.


 


SECTION 112. Legal Holidays . In any case where any Interest
Payment Date, Redemption Date, Repayment Date, sinking fund payment date, Stated Maturity or Maturity of any Security or the last date
on which a Holder has the right to convert or exchange a Security shall not be a Business Day at any Place of Payment, then (notwithstanding
any other provision of this Indenture or any Security or coupon other than a provision in the Securities of any series which specifically
states that such provision shall apply in lieu hereof), payment of interest or principal (and premium or Make-Whole Amount, if any) or
conversion or exchange of such Security need not be made at such Place of Payment on such date, but (except as otherwise provided in the
supplemental indenture with respect to such Security) may be made on the next succeeding Business Day at such Place of Payment with the
same force and effect as if made on the Interest Payment Date, Redemption Date, Repayment Date or sinking fund payment date, or at the
Stated Maturity or Maturity, or on such last day for conversion or exchange, provided that no interest shall accrue on the amount so payable
for the period from and after such Interest Payment Date, Redemption Date, Repayment Date, sinking fund payment date, Stated Maturity
or Maturity, as the case may be.


 






    12


    


    

 


SECTION 113. Limited Liability; Immunity of Shareholders, Directors,
Officers and Agents of the Company . Notwithstanding any other provision of this Indenture or of the Securities of any series to the
contrary, no recourse under or upon any obligation, covenant or agreement contained in this Indenture or in any Security, or for the payment
of any sums due on account of any indebtedness evidenced thereby, including without limitation principal, premium or interest, if any,
or for any claim based on this Indenture or any Security or otherwise in respect of this Indenture or any Security, shall be had, whether
by levy or execution or otherwise, against


 


(i) the Company, the Company’s assets or against any past,
present or future shareholder, 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.


 


SECTION 114. Conflict with Trust Indenture Act . If any
provision hereof limits, qualifies or conflicts with another provision hereof which is required or deemed to be included in this Indenture
by any of the provisions of the Trust Indenture Act, such required provision shall control. If any provision of this Indenture modifies
or excludes any provision of the Trust Indenture Act that may be so modified or excluded, the latter provision shall be deemed to apply
to this Indenture as so modified or to be excluded, as the case may be.

form, Euroclear or Clearstream.


 


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

upon which such conversion shall be effected (including, without limitation, the initial conversion price or rate, the conversion period,
any adjustment of the applicable conversion price and any requirements relative to the reservation of such shares for purposes of conversion);

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 Chair of the Board, its Chief
Executive Officer, its President, or one of its Vice Presidents, under its corporate seal reproduced thereon, and attested by its Secretary
or one of its Assistant Secretaries. The signature of any of these officers on the Securities and coupons may be manual or facsimile signatures
of the present or any future such authorized officer and may be imprinted or otherwise reproduced on the Securities.


 


Securities and coupons bearing the manual or facsimile signatures of
individuals who were at any time the proper officers of the Company shall bind the Company, notwithstanding that such individuals or any
of them have ceased to hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at the
date of such Securities or coupons.


 






    17


    


    

 


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 calendar 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;


 


(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.


 






    18


    


    

 


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).


 






    19


    


    

 


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 calendar days prior to the Exchange Date, copies of which certificate shall be available from the offices of Euroclear and Clearstream,
the Trustee, any Authenticating Agent appointed for such series of Securities and each Paying Agent. Unless otherwise specified in such
temporary Global Security, any such exchange shall be made free of charge to the beneficial owners of such temporary Global Security,
except that a Person receiving definitive Securities must bear the cost of insurance, postage, transportation and the like unless such
Person takes delivery of such definitive Securities in person at the offices of Euroclear or Clearstream. Definitive Securities in bearer
form to be delivered in exchange for any portion of a temporary Global Security shall be delivered only to an address located outside
the United States.


 


Until exchanged in full as hereinabove provided, the temporary Securities
of any series shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of the same series
and of like tenor authenticated and delivered hereunder, except that, unless otherwise specified as contemplated by Section 301,
interest payable on a temporary Global Security on an Interest Payment Date for Securities of such series occurring prior to the applicable
Exchange Date shall be payable to Euroclear and Clearstream on such Interest Payment Date upon delivery by Euroclear and Clearstream to
the Trustee of a certificate or certificates in the form set forth in Exhibit B-2 to this Indenture (or in such other forms
as may be established pursuant to Section 301), for credit without further interest on or after such Interest Payment Date to the
respective accounts of Persons who are the beneficial owners of such temporary Global Security on such Interest Payment Date and who have
each delivered to Euroclear or Clearstream, as the case may be, a certificate dated no earlier than 15 calendar 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.


 






    20


    


    

 


SECTION 305. Registration, Registration of Transfer, Conversion
and Exchange . The Company shall cause to be kept at the Corporate Trust Office of the Trustee or in any office or agency of the Company
in a Place of Payment a register for each series of Securities (the registers maintained in such office or in any such office or agency
of the Company in a Place of Payment being herein sometimes referred to collectively as the “Security Register”) in which,
subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Registered Securities and
of transfers of Registered Securities. The Security Register shall be in written form or any other form capable of being converted into
written form within a reasonable time. The Trustee, at its Corporate Trust Office, is hereby initially appointed “Security Registrar”
for the purpose of registering Registered Securities and transfers of Registered Securities on such Security Register as herein provided.
In the event that the Trustee shall cease to be Security Registrar, it shall have the right to examine, and be provided a copy of, the
Security Register at all reasonable times.


 


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


 


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


 


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.


 






    21


    


    

 


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 calendar 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 calendar 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.


 


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.


 






    22


    


    

 


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 calendar days before selection of the Securities to be redeemed under Section 1103 and ending at the
close of business on (A) if such Securities are issuable only as Registered Securities, the day of the mailing of the relevant notice
of redemption and (B) if such Securities are issuable as Bearer Securities, the day of the first publication of the relevant notice
of redemption or, if such Securities are also issuable as Registered Securities and there is no publication, the mailing of the relevant
notice of redemption, or (ii) to register the transfer of or exchange any Registered Security so selected for redemption in whole
or in part, except, in the case of any Registered Security to be redeemed in part, the portion thereof not to be redeemed, or (iii) to
exchange any Bearer Security so selected for redemption except that such a Bearer Security may be exchanged for a Registered Security
of that series and like tenor, provided that such Registered Security shall be simultaneously surrendered for redemption, or (iv) to
issue, register the transfer of or exchange any Security which has been surrendered for repayment at the option of the Holder, except
the portion, if any, of such Security not to be so repaid.


 


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


 


SECTION 306. Mutilated, Destroyed, Lost and Stolen Securities
.. If any mutilated Security or a Security with a mutilated coupon appertaining to it is surrendered to the Trustee or the Company, together
with, in proper cases, such security or indemnity as may be required by the Company or the Trustee to save each of them or any agent of
either of them harmless, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security
of the same series and principal amount, containing identical terms and provisions and bearing a number not contemporaneously outstanding,
with coupons corresponding to the coupons, if any, appertaining to the surrendered Security.


 


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.


 






    23


    


    

 


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


 


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


 


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


 


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


 


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


 


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


 


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


 


(1) The Company may elect to make payment of any Defaulted
Interest to the Persons in whose names the Registered Securities of such series (or their respective Predecessor Securities) are registered
at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner.
The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Registered Security of
such series and the date of the proposed payment (which shall not be less than 20 calendar 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 calendar days and not less
than 10 calendar days prior to the date of the proposed payment and not less than 10 calendar 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 calendar 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.


 






    24


    


    

 


(2) The Company may make payment of any Defaulted Interest
on the Registered Securities of any series in any other lawful manner not inconsistent with the requirements of any over-the-counter market
or securities exchange on which such Securities may be quoted or listed, and upon such notice as may be required by such market or exchange,
if, after notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be
deemed practicable by the Trustee.


 


Subject to the foregoing provisions of this Section and Section 305,
each Security delivered under this Indenture upon registration of transfer of or upon conversion of or in exchange for or in lieu of any
other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security.


 


SECTION 308. Persons Deemed Owners . Prior to due presentment
of a Registered Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat
the Person in whose name such Registered Security is registered as the owner of such Security for the purpose of receiving payment of
principal of (and premium or Make-Whole Amount, if any), and (subject to Sections 305 and 307) interest on, such Registered Security and
for all other purposes whatsoever, whether or not such Registered Security be overdue, and neither the Company, the Trustee nor any agent
of the Company or the Trustee shall be affected by notice to the contrary. All such payments so made to any such Person, or upon such
Person’s order, shall be valid, and, to the extent of the sum or sums so paid, effectual to satisfy and discharge the liability
for money payable upon any such Security.


 


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


 


No holder of any beneficial interest in any Global Security held on
its behalf by a depository shall have any rights under this Indenture with respect to such Global Security and such depository (which
is the Holder of such security) shall be treated by the Company, the Trustee, and any agent of the Company or the Trustee as the owner
of such Global Security for all purposes whatsoever. None of the Company, the Trustee, any Paying Agent or the Security Registrar will
have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests
of a Global Security or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.


 






    25


    


    

 


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


 


SECTION 309. Cancellation . All Securities and coupons
surrendered for payment, redemption, repayment at the option of the Holder, registration of transfer or conversion or exchange or for
credit against any sinking fund payment shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee, and any
such Securities and coupons and Securities and coupons surrendered directly to the Trustee for any such purpose, upon direction by the
Company, shall be promptly cancelled by it. The Company may at any time deliver to the Trustee for cancellation any Securities previously
authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and may deliver to the Trustee (or
to any other Person for delivery to the Trustee) for cancellation any Securities previously authenticated hereunder which the Company
has not issued and sold, and all Securities so delivered shall be promptly cancelled by the Trustee. If the Company shall so acquire any
of the Securities, however, such acquisition shall not operate as a redemption or satisfaction of the indebtedness represented by such
Securities unless and until the same are surrendered to the Trustee for cancellation. No Securities shall be authenticated in lieu of
or in exchange for any Securities cancelled as provided in this Section, except as expressly permitted by this Indenture. Cancelled Securities
and coupons held by the Trustee shall be disposed of by the Trustee in accordance with its customary practices (subject to the record
retention requirements of the Exchange Act).


 


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


 


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


 


ARTICLE 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


 






    26


    


    

 


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


 


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


 


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


 


ARTICLE FIVE—REMEDIES


 


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


 


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


 






    27


    


    

 


(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 90 calendar 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 33% 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 a minimum amount to be specified in
a prospectus supplement, 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 calendar 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


 


(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 calendar 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 33% 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.


 






    28


    


    

 


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 calendar days, or


 


(2) default is made in the payment of the
principal of (or premium or Make-Whole Amount, if any, on) any Security of any series at its Maturity,


 


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


 


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


 


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


 






    29


    


    

 


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


 


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


 


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


 


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


 


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


 


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


 


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


 


SECTION 506. Application of Money Collected. Any money

and


 






    30


    


    

 


THIRD: To the payment of the remainder, if any,

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


 


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


 


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


 


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


 


(4) the Trustee for 60 calendar 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.


 


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.


 






    31


    


    

 


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.


 


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

ARTICLE SIX—THE TRUSTEE


 


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


 


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


 


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


 


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


 


(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;


 






    33


    


    

 


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


 


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


 


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


 


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


 


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


 


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


 


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


 


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


 


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


 


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


 


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


 


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


 






    34


    


    

 


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.


 


SECTION 607. Corporate Trustee Required; Eligibility; Conflicting
Interests. There shall at all times be a Trustee hereunder which shall be eligible to act as Trustee under TIA Section 310(a)(1) and
shall have at all times a combined capital and surplus of at least $50,000,000 (or which shall have a combined capital and surplus of
at least $10,000,000 and whose ultimate parent holding company shall have a combined capital and surplus of at least $50,000,000. If the
Trustee publishes reports of condition at least annually, pursuant to law or the requirements of Federal, state, territorial or District
of Columbia supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of the Trustee
shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time
the Trustee shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and
with the effect hereinafter specified in this Article. Neither the Company nor any Person directly or indirectly controlling, controlled
by, or under common control with the Company shall serve as Trustee.


 


SECTION 608. Resignation and Removal; Appointment of Successor.


 


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


 


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


 






    35


    


    

 



 


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


 


(d) If at any time:


 


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


 


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


 


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


 


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


 






    	 	36	 



     


    

 


(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.


 


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.


 






    	 	37	 



     


    

 


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

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

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

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;

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.

first part, and the predecessor corporation, except in the event of a lease, shall be relieved of any further obligation under this Indenture

been signed and delivered by the officers of the Company to the Trustee for authentication, and any Securities which such successor corporation
thereafter shall cause to be signed and delivered to the Trustee for that purpose. All the Securities so issued shall in all respects
have the same legal rank and benefit under this Indenture as the Securities theretofore or thereafter issued in accordance with the terms

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

(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

payment of principal of and any premium or Make-Whole Amount and interest on any Bearer Security shall be made at the office of the Company’s
Paying Agent in the Borough of Manhattan, The City of New York, if (but only if) payment in Dollars of the full amount of such principal,
premium or Make-Whole Amount, or interest, as the case may be, at all offices or agencies outside the United States maintained for the
purpose by the Company in accordance with this Indenture, is illegal or effectively precluded by exchange controls or other similar restrictions.


 


The Company may from time to time designate one or more other offices
or agencies (in or outside the Place of Payment) where the Securities of one or more series may be presented or surrendered for any or
all of such purposes, and may from time to time rescind such designations; provided, however, that no such designation or
rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in accordance with the requirements
set forth above for Securities of any series for such purposes. The Company will give prompt written notice to the Trustee of any such
designation or rescission and of any change in the location of any such other office or agency. Unless otherwise specified with respect
to any Securities pursuant to Section 301 with respect to a series of Securities, the Company hereby designates as a Place of Payment
for each series of Securities, each of (i) the office or agency of the Company in the Borough of Manhattan, The City of New York,

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 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

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

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


 


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


 


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


 


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


 


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 calendar 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. Statement as to Compliance. The Company will
deliver to the Trustee, within 120 calendar 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 1005, such compliance shall be determined without regard to any period of grace or requirement of notice
under this Indenture.


 






    	 	46	 



     


    

 


SECTION 1006. 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 and 1005, 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 calendar days prior to the
giving of the notice of redemption in Section 1104 (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee
of such Redemption Date and of the principal amount of Securities of such series to be redeemed. In the case of any redemption of Securities
prior to the expiration of any restriction on such redemption provided in the terms of such Securities or elsewhere in this Indenture,
the Company shall furnish the Trustee with an Officers’ Certificate evidencing compliance with such restriction.


 


SECTION 1103. Selection by Trustee of Securities to Be Redeemed.
If less than all the Securities of any series issued on the same day with the same terms are to be redeemed, the particular Securities
to be redeemed shall be selected not more than 60 calendar 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 10 calendar days nor more than 60 calendar 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,


 






    	 	47	 



     


    

 


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


 


(4) in case any Security is to be redeemed in part only,
the notice which relates to such Security shall state that on and after the Redemption Date, upon surrender of such Security, the holder
will receive, without a charge, a new Security or Securities of authorized denominations for the principal amount thereof remaining unredeemed,


 


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


 


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


 


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


 


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


 


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


 


(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.


 


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.


 






    	 	48	 



     


    

 


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 Ordinary Shares or Preference Shares, 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.


 


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


 


SECTION 1107. Securities Redeemed in Part. Any Registered
Security which is to be redeemed only in part (pursuant to the provisions of this Article or of Article Twelve) shall be surrendered
at a Place of Payment therefor (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer
in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or his attorney duly authorized in writing) and
the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Security without service charge a new Security
or Securities of the same series, of any authorized denomination as requested by such Holder in aggregate principal amount equal to and
in exchange for the unredeemed portion of the principal of the Security so surrendered. If a Global Security is so surrendered, the Company
shall execute and the Trustee shall authenticate and deliver to the depository, without service charge, a new Global Security in a denomination
equal to and in exchange for the unredeemed portion of the principal of the Global Security so surrendered.


 


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.


 






    	 	49	 



     


    

 


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


 


SECTION 1203. Redemption of Securities for Sinking Fund.
Not less than 60 calendar 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 calendar 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.


 






    	 	50	 



     


    

 


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 calendar days nor later than 30 calendar 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) electronic transmission, 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 electronic transmission, facsimile transmission or letter; provided, however, that such electronic transmission,
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.


 


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


 


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


 


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


 


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

ARTICLE FOURTEEN—DEFEASANCE AND COVENANT
DEFEASANCE


 


SECTION 1401. Applicability of Article; Company’s Option

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


 


SECTION 1402. Defeasance and Discharge . Upon the Company’s
exercise of the above option applicable to this Section with respect to any Securities of or within a series, the Company shall be
deemed to have been discharged from its obligations with respect to such Outstanding Securities and any coupons appertaining thereto on
the date the conditions set forth in Section 1404 are satisfied (hereinafter, “Defeasance”). For this purpose, such Defeasance
means that the Company shall be deemed to have paid and discharged the entire indebtedness represented by such Outstanding Securities
and any coupons appertaining thereto, which shall thereafter be deemed to be “Outstanding” only for the purposes of Section 1405
and the other Sections of this Indenture referred to in clauses (A) and (B) below, and to have satisfied all of its other obligations
under such Securities and any coupons appertaining thereto and this Indenture insofar as such Securities and any coupons appertaining
thereto are concerned (and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging the same), except
for the following which shall survive until otherwise terminated or discharged hereunder: (A) the rights of Holders of such Outstanding
Securities and any coupons appertaining thereto to receive, solely from the trust fund described in Section 1404 and as more fully
set forth in such Section, payments in respect of the principal of (and premium or Make-Whole Amount, if any) and interest, if any, on
such Securities and any coupons appertaining thereto when such payments are due, (B) the Company’s obligations with respect
to such Securities under Sections 305, 306, 1002 and 1003, and 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 and 1005, 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 and 1005, 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.

a series and any coupons appertaining thereto:

specifically pledged as security for, and dedicated solely to, the benefit of the Holders of such Securities and any coupons appertaining
thereto, (1) an amount in such currency, currencies or currency unit in which such Securities and any coupons appertaining thereto

any time during the period ending on the 91st calendar day after the date of such deposit (it being understood that this condition shall
not be deemed satisfied until the expiration of such period).


 


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


 


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


 


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


 


(g) 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.


 






    	 	53	 



     


    

 


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


 


Unless otherwise specified with respect to any Security pursuant to
Section 301, if, after a deposit referred to in Section 1404(a) has been made, (a) the Holder of a Security in respect
of which such deposit was made is entitled to, and does, elect pursuant to Section 301 or the terms of such Security to receive payment
in a currency or currency unit other than that in which the deposit pursuant to Section 1404(a) has been made in respect of
such Security, or (b) a Conversion Event occurs in respect of the currency or currency unit in which the deposit pursuant to Section 1404(a) has
been made, the indebtedness represented by such Security and any coupons appertaining thereto shall be deemed to have been, and will be,
fully discharged and satisfied through the payment of the principal of (and premium or Make-Whole Amount, if any), and interest, if any,
on such Security as the same becomes due out of the proceeds yielded by converting (from time to time as specified below in the case of
any such election) the amount or other property deposited in respect of such Security into the currency or currency unit in which such
Security becomes payable as a result of such election or Conversion Event based on the applicable market exchange rate for such currency
or currency unit in effect on the second Business Day prior to each payment date, except, with respect to a Conversion Event, for such
currency or currency unit in effect (as nearly as feasible) at the time of the Conversion Event.


 


The Company shall pay and indemnify the Trustee against any tax, fee
or other charge imposed on or assessed against the Government Obligations deposited pursuant to Section 1404 or the principal and
interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of such
Outstanding Securities and any coupons appertaining thereto.


 


Anything in this Article to the contrary notwithstanding, subject
to Section 606, the Trustee shall deliver or pay to the Company from time to time upon Company Request any money or Government Obligations
(or other property and any proceeds therefrom) held by it as provided in Section 1404 which, in the opinion of a nationally recognized
firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, are in excess of the amount
thereof which would then be required to be deposited to effect a Defeasance or Covenant Defeasance, as applicable, in accordance with
this Article.

(ii) the principal amount of the Outstanding Securities
of such series that vote in favor of such request, demand, authorization, direction, notice, consent, waiver or other action shall be
taken into account in determining whether such request, demand, authorization, 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 chair 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 chair. A permanent chair 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 chair of the meeting to be not Outstanding. The chair of the meeting shall have no right
to vote, except as a Holder of a Security of such series or proxy.

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 chair 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 chair 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

ARTICLE SIXTEEN—CONVERSION OF SECURITIES


 


SECTION 1601. Applicability of Article; Conversion Privilege
and Conversion Price . Securities of any series which are convertible shall be convertible in accordance with their terms and (except
as otherwise specified as contemplated by Section 301 for Securities of any series) in accordance with this Article Sixteen.
Subject to and upon compliance with the provisions of this Article Sixteen, at any time during the period specified in the Securities,
at the option of the Holder thereof, any Security or any portion of the principal amount thereof which is $1,000 or an integral multiple
of $1,000 may be converted at the principal amount thereof, or of such portion thereof, into fully paid and nonassessable Ordinary Shares
(calculated as to each conversion to the nearest 1/100 of a share) 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 Ordinary Shares shall be delivered upon conversion
(herein called the “Conversion Price”) of Securities of any series shall be specified in such Securities. The Conversion Price
shall be adjusted in certain instances as provided in Section 1604.


 


In case the Company shall, by dividend or otherwise, declare or make
a distribution on its Ordinary Shares referred to in paragraph (4) of Section 1604, the Holder of each Security, upon the conversion
thereof pursuant to this Article Sixteen subsequent to the close of business on the date fixed for the determination of shareholders
entitled to receive such distribution and prior to the effectiveness of the Conversion Price adjustment in respect of such distribution
pursuant to paragraph (4) of Section 1604, shall be entitled to receive for each Ordinary Share into which such Security is
converted, the portion of the evidence of indebtedness, Share Capital or assets so distributed applicable to one Ordinary Share; 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 Ordinary Shares 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, Share Capital 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 Ordinary Share 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 Ordinary Shares receiving such distribution.


 


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


 






    	 	57	 



     


    

 


The Company’s delivery to the Holder of the fixed number of Ordinary
Shares of the Company (and any cash in lieu of any fractional Ordinary Shares) 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 Ordinary Shares 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 Ordinary
Shares issuable upon conversion shall be treated for all purposes as the record holder or holders of such Ordinary Shares 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 Ordinary Shares issuable upon conversion, together with payment in lieu of any fraction of a share,
as provided in Section 1603.


 


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


 


SECTION 1603. Fractions of Shares . No fractional Ordinary
Shares 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 Ordinary Shares 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 Ordinary Shares
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 American Depositary Share on the day of conversion (or, if such day is not a Trading Day, on the Trading Day immediately preceding
such day).


 


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


 


(1) If the Company pays or makes a dividend
or other distribution (a) on its Ordinary Shares exclusively in Ordinary Shares or (b) on any other class of Share Capital of
the Company, which dividend or distribution includes Ordinary Shares of the Company, the Conversion Price in effect at the opening of
business on the day following the date fixed for the determination of shareholders 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 Ordinary Shares 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 Ordinary Shares 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 Ordinary Shares . The
Company shall not pay any dividend or make any distribution on shares of Ordinary Shares 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 Ordinary Shares consisting exclusively of Short Term Rights
(as defined below), or otherwise issues Short Term Rights to all holders of its Ordinary Shares , the Conversion Price in effect at the
opening of business on the day following the record date for the determination of holders of Ordinary Shares 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 Ordinary Shares of the Company outstanding at the close of business on the Rights Record Date plus
the number of Ordinary Shares of the Company which the aggregate of the offering price of the total number Ordinary Shares so offered
for subscription or purchase would purchase at such current market price and the denominator shall be the number Ordinary Shares of the
Company outstanding at the close of business on the Rights Record Date plus the number of Ordinary Shares 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 Ordinary Shares 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
Ordinary Shares of the Company. The Company shall not issue any rights, options or warrants in respect of its Ordinary Shares held in
the treasury of the Company. When used in this Section 1604, the term “Short Term Rights” shall mean rights, warrants
or options entitling the holders thereof (for a period commencing no earlier than the Rights Record Date and expiring not more than 45
calendar days after the Rights Record Date) to subscribe for or purchase Ordinary Shares of the Company at a price per share less than
the current market price per share (determined as provided in paragraph (7) of this Section 1604) of the Ordinary Shares of
the Company on the Rights Record Date.


 






    	 	58	 



     


    

 


(3) In case outstanding Ordinary Shares of
the Company shall be subdivided into a greater number of Ordinary Shares , 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
Ordinary Shares of the Company shall be combined into a smaller number of Ordinary Shares , 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 Ordinary Shares evidences
of its indebtedness, shares of any class of Share Capital of the Company or other assets (other than cash dividends out of current or
retained earnings), or (b) distributes to substantially all holders of Ordinary Shares rights or warrants to subscribe for securities
(other than Short Term Rights to which paragraph (2) of this Section 1604 applies), the Conversion Price shall be reduced by
multiplying such Conversion Price by a fraction of which the numerator shall be the current market price per share (determined as provided
in paragraph (7) of this Section 1604) of the Ordinary Shares 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 Ordinary Shares (collectively, the “Market Value of the Distribution”)
and the denominator shall be such current market price per share of the Ordinary Shares 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 calendar days after notice relating to such distribution is required to
be given pursuant to Section 1606(a). If the Board of Directors determines the fair market value of any distribution for purposes
of this paragraph (4) by reference to the actual or when issued trading market for any securities comprising such distribution, it
must in doing so consider the prices in such market over the same period used in computing the current market price per share pursuant
to paragraph (7) of this Section 1604. In the event that, with respect to any distribution to which this paragraph (4) of
Section 1604 would otherwise apply, the Market Value of the Distribution is greater than the current market price per share of the
Ordinary Shares (such distribution being referred to herein as an “Unadjusted Distribution”), then the adjustment provided
by this paragraph (4) shall not be made and in lieu thereof the provisions of Section 1611 shall apply with respect to such
Unadjusted Distribution.


 


(5) The Company may, but shall not be required
to, make such reductions in the Conversion Price, in addition to those required by paragraphs (1), (2), (3), and (4) of this Section 1604,
as it considers to be advisable in order that any event treated for federal income tax purposes as a dividend of share or share 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 Ordinary Shares have the right to participate.


 






    	 	59	 



     


    

 


(6) Rights or warrants issued or distributed
by the Company to all holders of its Ordinary Shares entitling the holders thereof to subscribe for or purchase Ordinary Shares or Preference
Shares, which rights or warrants (i) are deemed to be transferred with such Ordinary Shares , (ii) are not exercisable and (iii) are
also issued or distributed in respect of future issuances of Ordinary Shares , in each case in clauses (i) through (iii) until
the occurrence of a specified event or events (“Trigger Events”), shall for purposes of this Section 1604 not be deemed
issued or distributed until the occurrence of the earliest Trigger Event. Each Ordinary Share issued upon conversion of Securities pursuant
to this Article Sixteen shall be entitled to receive the appropriate number of Ordinary Shares purchase rights (the “Rights”),
if any, and the certificates representing the Ordinary Shares issued upon conversion shall bear such legends, if any. Notwithstanding
anything to the contrary in this Article Sixteen, there shall not be any adjustment to the Conversion Price as a result of (i) the
distribution of separate certificates representing the Rights; (ii) the occurrence of certain events entitling holders of Rights
to receive, upon exercise thereof, Ordinary Shares 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 Ordinary Shares pursuant
to a Company plan providing for reinvestment of dividends or interest.


 


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


 


(8) No adjustment in the Conversion Price
shall be required unless such adjustment would require an increase or decrease of at least 1% in the Conversion Price; provided,
however, that any adjustments which by reason of this paragraph (8) are not required to be made shall be carried forward and
taken into account in any subsequent adjustment. All calculations under this Article Sixteen shall be made to the nearest cent or
to the nearest one-hundredth of an Ordinary Share, 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 shareholders, legally abandon its plan to pay such dividend or distribution,
the Conversion Price then in effect hereunder, if changed to reflect such dividend or distribution, shall upon the legal abandonment of
such plan be changed to the Conversion Price which would have been in effect at the time of such abandonment (after giving effect to all
other adjustments not so legally abandoned pursuant to the provisions of this Article Sixteen) had such dividend or distribution
never been declared.


 


(10) Notwithstanding any other provision of
this Section 1604, no adjustment to the Conversion Price shall reduce the Conversion Price below the then nominal value per share
of the Ordinary Shares 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 nominal value per share of the Ordinary Shares is at all times equal to or less than the Conversion Price.


 


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

and, if applicable, the date as of which it is expected that holders of Ordinary Shares of record shall be entitled to exchange their

transfer, dissolution, liquidation or winding up.


 


SECTION 1607. Company to Reserve Ordinary Shares . The
Company shall at all times reserve and keep available, free from preemptive rights, out of its authorized but unissued Ordinary Shares,
for the purpose of effecting the conversion of Securities, a number of shares of Ordinary Shares for the conversion of all outstanding

SECTION 1608. Taxes on Conversion . The Company will pay
any and all taxes that may be payable in respect of the issue or delivery Ordinary Shares 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 Ordinary Shares 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

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


 


SECTION 1611. Provisions in Case of Consolidation, Merger or
Sale of Assets; Special Distributions . If any of the following shall occur, namely: (i) any reclassification or change of outstanding
Ordinary Shares 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 Ordinary Shares or (iii) any sale or conveyance of all or substantially all of the
property or business of the Company as an entirety, then the Person formed by such consolidation or resulting from such merger or which
acquires such properties or assets, as the case may be, shall as a condition precedent to such transaction execute and deliver to the
Trustee a supplemental indenture providing that the Holder of each Security then outstanding shall have the right thereafter, during the
period such Security shall be convertible as specified in Section 1601, to convert such Security only into the kind and amount of
securities, cash and other property receivable, if any, upon such consolidation, merger, sale, transfer or lease by a holder of the number
of Ordinary Shares 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 Ordinary Shares referred to in the foregoing sentence:


 


(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 Ordinary Share of the Company in respect of which such rights of election shall not have been exercised, then for
the purpose of this Section 1611 the kind and amount of securities, cash and other property receivable upon such consolidation, merger,
sale, transfer or lease shall be deemed to be the kind and amount so receivable per share by a plurality of such shares of Ordinary Shares
).


 


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


 


In the event the Company shall execute a supplemental indenture pursuant
to this Section 1611, the Company shall promptly file with the Trustee an Officers’ Certificate briefly stating the reasons
therefor, the kind or amount of shares 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 Ordinary
Shares that constitutes an Unadjusted Distribution pursuant to the last sentence of paragraph (4) of Section 1604, then, from
and after the record date for determining the holders of Ordinary Shares 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 Ordinary Shares into which the Security is convertible, the kind and amount of
evidences of indebtedness, Share Capital, 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.


 






    	 	62	 



     


    

 


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


 


SECTION 1613. When No Adjustment Required . Except as expressly
set forth in Section 1604, no adjustment in the Conversion Price shall be made because the Company issues, in exchange for cash,
property or services, shares of its Ordinary Shares, or any securities convertible into or exchangeable for its Ordinary Shares, or securities
(including warrants, rights and options) carrying the right to subscribe for or purchase shares of its Ordinary Shares 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 1604 in respect of any dividend or distribution if the Holders may participate
therein (on a basis to be determined in good faith by the Board of Directors) and receive the same consideration they would have received
if they had converted the Securities immediately prior to the record date with respect to such dividend or distribution.


 


SECTION 1614. Equivalent Adjustments . In the event that,
as a result of an adjustment made pursuant to Section 1604 above, the holder of any Security thereafter surrendered for conversion
shall become entitled to receive any Share Capital of the Company other than shares of its Ordinary Shares, 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 Ordinary Shares contained in this Article Sixteen.
