particular application or request, no additional certificate or opinion need be furnished.

 

Every

Section
1.3. FORM OF DOCUMENTS DELIVERED TO TRUSTEE. In any case where several matters are required to be certified by, or covered by an opinion
of, any specified Person, it is not necessary that all such matters be certified by, or covered by the opinion of, only one such Person,
or that they be so certified or covered by only one document, but one such Person may certify or give an opinion with respect to some
matters and one or more other such Persons as to other matters, and any such Person may certify or give an opinion as to such matters
in one or several documents.

 

Any
certificate or opinion of an officer of the Company may be based, insofar as it relates to legal matters, upon a certificate or opinion
of, or representations by, counsel, unless such officer knows that the certificate or opinion or representations with respect to the
matters upon which his certificate or opinion is based are erroneous. Any such certificate or Opinion of Counsel may be based, insofar
as it relates to factual matters, upon a certificate or opinion of, or representations by, an officer or officers of the Company stating
that the information with respect to such factual matters is in the possession of the Company, unless such counsel knows that the certificate
or opinion or representations as to such matters are erroneous.

 

Any
certificate or opinion of an officer of the Company or of counsel may be based, insofar as it relates to accounting matters, upon a certificate
or opinion of or representations by an accountant or firm of accountants in the employ of the Company, unless such officer or counsel,
as the case may be, knows that the certificate or opinions or representations as to such accounting matters are erroneous.

 

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
1.4. 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 may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by
such Holders in person or by agent duly appointed in writing; and, except as herein otherwise expressly provided, such action shall become
effective when such instrument or instruments are delivered to the Trustee and, where it is hereby expressly required, to the Company.
Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act”
of the Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such
agent shall be sufficient for any purpose of this Indenture and conclusive in favor of the Trustee and the Company, if made in the manner
provided in this Section.

 

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

 

(c)
The ownership of Registered Securities shall be proved by the Register (as defined in Section 3.5 below).

 

    9

    

    

 

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

 

(e)
If the Company shall solicit from the Holders of any series any request, demand, authorization, direction, notice, consent, waiver or
other Act, the Company may, at its option, fix in advance a record date for the determination of Holders of such series entitled to give
such request, demand, authorization, direction, notice, consent, waiver or other Act, but the Company shall have no obligation to do
so. 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 such series 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 of such series
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 of such series 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 taken on or prior to the applicable Expiration
Date (as defined below) by Holders of the requisite amount of Outstanding Securities of such series on such record date. Nothing in this
paragraph shall be construed to prevent the Company from setting a new record date for any action for which a record date has previously
been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be
cancelled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the
requisite amount of Outstanding Securities of any series on the date such action is taken. Promptly after any record date is set pursuant
to this paragraph, the Company, at its own expense, shall cause notice of such record date, the proposed action by Holders and the applicable
Expiration Date to be given to the Trustee in writing and to each Holder of Securities in the manner set forth in Section 1.6.

 

With
respect to any record date set pursuant to this Section 1.4, the Company may designate any date as the “Expiration Date”
and from time to time may change the Expiration Date to any earlier or later day; provided that no such change shall be effective unless
notice of the proposed new Expiration Date is given to the Trustee, and to each Holder of Securities of the applicable series in the
manner set forth in Section 1.6 on or prior to the existing Expiration Date. If an Expiration Date is not designated with respect to
any record date pursuant to this Section, the Company shall be deemed to have initially designated the 180th day after such record date
as the Expiration Date with respect thereto, subject to its right to change the Expiration Date as provided in this paragraph. Notwithstanding
the foregoing, no Expiration Date shall be later than the 180th day after the applicable record date.

 

(f)
Without limiting the foregoing, a Holder entitled hereunder to take any action hereunder with regard to any particular Security may do
so with regard to all or any part of the principal amount of such Security or by one or more duly appointed agents, each of which may
do so pursuant to such appointment with regard to all or any part of such principal amount.

 

(g)
The Company and the Trustee may make reasonable rules for action by or at a meeting of Holders.

[●]

 

Notices
to the Trustee are deemed given only upon actual receipt by the Trustee.

 

The
Company or the Trustee by notice to the other may designate additional or different addresses (including facsimile numbers and electronic
addresses) for subsequent notices or communications.

 

Any
notice or communication shall be in writing and delivered in person or mailed by first-class mail (registered or certified, return receipt
requested), facsimile transmission, electronic transmission or other similar means of unsecured electronic communication or overnight
air courier guaranteeing next day delivery.

 

Section
1.6. NOTICE TO HOLDERS; WAIVER. Where this Indenture provides for notice to Holders of any event, if any of the Securities affected by
such event are Registered Securities, such notice to the Holders thereof shall be sufficiently given (unless otherwise herein or in the
terms of such Securities 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 Register, within the time prescribed for the giving of such notice; provided that notices
given to Holders of Securities in global form may be given electronically through the facilities of the Depository.

 

In
any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to
any particular Holder shall affect the sufficiency of such notice with respect to other Holders of Registered Securities as provided
herein. In any case where notice is given to Holders by publication, neither the failure to publish such notice, nor any defect in any
notice so published, shall affect the sufficiency of such notice with respect to the sufficiency of any notice to Holders of Registered
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.

 

    11

    

    

 

If
by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice as
provided above, then such notification as shall be made with the approval of the Trustee (such approval not to be unreasonably withheld)
shall constitute a sufficient notification for every purpose hereunder. If it is impossible or, in the opinion of the Trustee, impracticable
to give any notice by publication in the manner herein required, then such publication in lieu thereof as shall be made with the approval
of the Trustee shall constitute a sufficient publication of such notice.

 

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 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
1.7. HEADINGS AND TABLE OF CONTENTS. The Article and Section headings herein and the Table of Contents are for convenience only and shall
not affect the construction hereof.

 

Section
1.8. SUCCESSOR AND ASSIGNS. All covenants and agreements in this Indenture by the Company shall bind its successor and assigns, whether
so expressed or not.

 

Any
act or proceeding that is required or permitted by any provision of this Indenture and that is authorized or required to be done or performed
by any board, committee or officer of the Company shall and may be done and performed with like force and effect by the like board, committee
or officer of any corporation that shall at the time be the successor or assign of the Company.

 

Section
1.9. SEPARABILITY. In case any provision of this Indenture or any Securities shall be invalid, illegal or unenforceable, the validity,
legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

 

Section
1.10. BENEFITS OF INDENTURE. Nothing in this Indenture or in any Securities, expressed or implied, shall give to any Person, other than
the parties hereto and their successors hereunder, any Agent and the Holders, any benefit or any legal or equitable right, remedy or
claim under this Indenture.

 

Section
1.11. GOVERNING LAW. UNLESS OTHERWISE PROVIDED WITH RESPECT TO ANY SECURITIES OF ANY SERIES PURSUANT TO SECTION 3.1, THIS INDENTURE AND
THE SECURITIES APPERTAINING THERETO SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, INCLUDING
ALL MATTERS OF CONSTRUCTION, VALIDITY AND PERFORMANCE. This Indenture is subject to the Trust Indenture Act and if any provision hereof
limits, qualifies or conflicts with a provision included in this Indenture which is required by the Trust Indenture Act, the latter 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, whether
or not such provision of this Indenture refers expressly to such provision of the Trust Indenture Act.

Section
1.12. WAIVER OF JURY TRIAL. EACH OF THE COMPANY, THE TRUSTEE AND EACH HOLDER (BY ITS ACCEPTANCE OF ANY SECURITY) HEREBY IRREVOCABLY WAIVES,
TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING
TO THIS INDENTURE, THE SECURITIES OR THE TRANSACTION CONTEMPLATED HEREBY. EACH OF THE COMPANY, THE TRUSTEE AND EACH HOLDER (BY ITS ACCEPTANCE
OF ANY SECURITY) HEREBY IRREVOCABLY SUBMITS TO THE JURISDICTION OF ANY STATE OR U.S. FEDERAL COURT IN THE CITY OF NEW YORK AND COUNTY
OF NEW YORK IN RESPECT OF ANY SUIT, ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THE INDENTURE AND THE SECURITIES, AND IRREVOCABLY

Section
1.13. LEGAL HOLIDAYS. Unless otherwise provided with respect to any Security or Securities pursuant to Section 3.1, in any case where
any Interest Payment Date, Redemption Date, sinking fund payment date, Stated Maturity or Maturity or other payment date of any Security
shall not be a Business Day at any Place of Payment, then, notwithstanding any other provision of this Indenture or any Security, payment
of principal, premium, if any or interest or other payments need not be made at such Place of Payment on such date, but may be made on
the next succeeding Business Day at such Place of Payment with the same force and effect as if made on such date; provided that no interest
shall accrue on the amount so payable for the period from and after such Interest Payment Date, Redemption Date, sinking fund payment
date, Stated Maturity or Maturity or other payment date, as the case may be.

 

Section
1.14. NO RECOURSE AGAINST OTHERS. No past, present or future director, officer, employee, agent, member, manager, trustee or stockholder,
as such, of the Company or any successor Person shall have any liability for any obligations of the Company or any successor Person,
either directly or through the Company or any successor Person, under the Securities or this Indenture or for any claim based on, in
respect of or by reason of such obligations or their creation, whether by virtue of any rule of law, statute or constitutional provision
or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise. By accepting a Security, each Holder agrees
to the provisions of this Section 1.14 and waives and releases all such liability. Such waiver and release shall be part of the consideration
for the issue of the Securities.

may provide that it shall represent the aggregate or specified amount of Outstanding Securities from time to time endorsed thereon and
may also provide that the aggregate amount of Outstanding Securities represented thereby may from time to time be reduced or increased
to reflect exchanges. Any endorsement of a Security in global form to reflect the amount, or any increase or decrease in the amount,
or changes in the rights of Holders, of Outstanding Securities represented thereby, shall be made in such manner and by such Person or
Persons as shall be specified therein or in the Company Order to be delivered to the Trustee pursuant to Section 3.3 or 3.4. Subject

by the Company with respect to endorsement or delivery or redelivery of a Security in global form shall be in writing but need not comply

may not be transferred except as a whole by the Depository to a nominee of the Depository or by a nominee of the Depository to the Depository
or another nominee of the Depository or by the Depository or any such nominee to a successor Depository or a nominee of such successor
Depository. Every Security authenticated and delivered upon registration of, or in exchange for, or in lieu of, this Security will be

(c)
The terms applicable to the Securities of any one series need not be identical but may vary as may be provided in an 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.

 

(d)
Except as may be otherwise expressly provided in the applicable supplemental indenture, as contemplated by this Section 3.1, the Securities
of any series shall rank PARI PASSU with the Securities of each other Series.

 

Section
3.2. DENOMINATIONS. Unless otherwise provided as contemplated by Section 3.1, any Securities of a series shall be issuable in denominations
of $1,000 and any integral multiple thereof.

 

Section
3.3. EXECUTION, AUTHENTICATION, DELIVERY AND DATING. Securities shall be executed on behalf of the Company by the Chief Executive Officer,
the Chief Financial Officer, the President, or any Vice President, the Treasurer or the Corporate Secretary of the Company. The seal
of the Company, if any, may be in the form of a facsimile thereof and may be impressed, affixed, imprinted or otherwise reproduced on
the Securities. The signatures of any of these officers on the Securities may be manual or facsimile.

 

Securities
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.

 

At
any time and from time to time, the Company may deliver Securities of any series executed by the Company to the Trustee for authentication,
together with a Company Order for the authentication and delivery of such Securities, and the Trustee in accordance with the Company
Order shall authenticate and deliver such Securities.

 

In
authenticating such Securities and accepting the additional responsibilities under this Indenture in relation to such Securities, the
Trustee shall be entitled to receive, and (subject to section 315(a) through (d) of the Trust Indenture Act) shall be fully protected
in relying upon, an Opinion of Counsel substantially to the effect that,

 

(1)
the form of such Securities have been established in conformity with the provisions of this Indenture;

 

(2)
the terms of such Securities have been, or in the case of Securities of a series offered in a Periodic Offering will be, established
in conformity with the provisions of this Indenture, subject in the case of Securities offered in a Periodic Offering, to any conditions
specified in such Opinion of Counsel; and

 

    19

    

    

 

(3)
such Securities, when authenticated and delivered by the Trustee, issued by the Company in accordance with the provisions of this Indenture,
and delivered to and duly paid for by the purchasers thereof, and subject to any conditions specified in such Opinion of Counsel, will
constitute legal, valid and binding obligations of the Company, enforceable in accordance with their terms, subject to bankruptcy, insolvency,
fraudulent transfer, reorganization, moratorium and other similar laws of general applicability relating to or affecting the enforcement
of creditors’ rights and to general equity principles and except further as enforcement thereof may be limited by or subject to
certain exceptions and qualifications specified in such Opinion of Counsel, including in the case of any Securities denominated in a
Foreign Currency, (A) requirements that a claim with respect to any Securities denominated other than in Dollars (or a foreign currency
or foreign currency unit judgment in respect of such claim) be converted into Dollars at a rate of exchange prevailing on a date determined
pursuant to applicable law or (B) governmental authority to limit, delay or prohibit the making of payments in foreign currency or currency
units or payments outside the United States.

 

Such
Opinion of Counsel need express no opinion as to whether a court in the United States would render a money judgment in a currency other
than that of the United States. Such counsel may rely on opinions of other counsel (copies of which shall be delivered to the Trustee),
and, to the extent such opinion involves factual matters, such counsel may rely upon certificates of officers of the Company and certificates
of public officials.

 

The
Trustee shall have the right to decline to execute any supplemental indenture establishing the terms of or the form of such Securities
if, in the written opinion of counsel to the Trustee (which counsel may be an employee of the Trustee), such action may not lawfully
be taken, or if the Trustee, in good faith by a Responsible Officer of the Trustee, shall determine, in its sole discretion, that such
action would adversely affect it.

 

Notwithstanding
the provisions of Section 3.1 and of the two preceding paragraphs, if all of the Securities of any series are not to be issued at one
time, it shall not be necessary to deliver the Officer’s Certificate otherwise required pursuant to Section 3.1 or the Company
Order and Opinion of Counsel otherwise required pursuant to the two preceding paragraphs in connection with the authentication of each
Security of such series if such documents, with appropriate modifications to cover such future issuances, are delivered at or prior to
the authentication upon original issuance of the first Security of such series to be issued.

 

With
respect to Securities of a series offered in a Periodic Offering, the Trustee may rely, as to the authorization by the Company of any
of such Securities, the form and terms thereof and the legality, validity, binding effect and enforceability thereof, upon the Opinion
of Counsel and the other documents delivered pursuant to Sections 2.1 and 3.1 and this Section, as applicable, in connection with the
first authentication of Securities of such series.

 

If
the Company shall establish pursuant to Section 3.1 that the Securities of a series are to be issued in whole or in part in global form,
then, unless otherwise provided with respect to such Securities pursuant to Section 3.1, the Company shall execute and the Trustee shall,
in accordance with this Section and the Company Order with respect to such series, authenticate and deliver one or more Securities in
global form that (i) shall represent and shall be denominated in an amount equal to the aggregate principal amount of the Outstanding
Securities of such series to be represented by such Security or Securities in global form, (ii) shall be registered, if a Registered
Security, in the name of the Depository for such Security or Securities in global form or the nominee of such Depository, (iii) shall
be delivered by the Trustee to such Depository or pursuant to such Depository’s instruction and (iv) shall bear the legend set
forth in Section 2.4.

 

    20

    

    

 

Unless
otherwise established pursuant to Section 3.1, each Depository designated pursuant to Section 3.1 for a Registered Security in global
form must, at the time of its designation and at all times while it serves as Depository, be a clearing agency registered under the Securities
Exchange Act of 1934, as amended, and any other applicable statute or regulation. Neither the Company nor the Trustee shall have any
responsibility to determine if the Depository is so registered.

 

Each
Depository shall enter into an agreement with the Company and the Trustee, as agent, governing the respective duties and rights of such
Depository, the Company and the Trustee, as agent, with regard to Securities of a series issued in global form.

 

Each
Registered Security shall be dated the date of its authentication as contemplated by Section 3.1.

 

No
Security shall be entitled to any benefits under this Indenture or be valid or obligatory for any purpose until authenticated by the
manual signature of one of the authorized signatories of the Trustee or an Authenticating Agent. Such signature upon any Security shall
be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered under this Indenture and
is entitled to the benefits of this Indenture.

 

Notwithstanding
the foregoing, if any Security shall have been authenticated and delivered hereunder but never issued and sold by the Company, and the
Company shall deliver such Security to the Trustee for cancellation as provided in Section 3.9 together with a written statement (which
need not comply with Section 1.2 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 not be entitled to the benefits of this Indenture.

 

Section
3.4. TEMPORARY SECURITIES. Pending the preparation of definitive Securities of any series, the Company may execute and, upon Company
Order, the Trustee shall authenticate and deliver temporary Securities of such series which are printed, lithographed, typewritten, mimeographed
or otherwise produced, in any authorized denomination, substantially of the tenor and form, of the definitive Securities in lieu of which
they are issued and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities
may determine, as conclusively evidenced by their execution of such Securities. In the case of Securities of any series, all or a portion
of such temporary Securities may be in global form.

 

    21

    

    

 

Except
in the case of temporary Securities in global form, each of which shall be exchanged in accordance with the provisions thereof, if temporary
Securities of any series are issued, the Company will cause definitive Securities of such series to be prepared without unreasonable
delay. After 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 pursuant to
Section 9.2 in a Place of Payment for such series, without charge to the Holder. Upon surrender for cancellation of any one or more temporary
Securities of any series, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a like principal
amount of definitive Securities of the same series of authorized denominations and of like tenor. Until so exchanged, the temporary Securities
of any series shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of such series except
as otherwise specified as contemplated by Section 3.1.

 

Section
3.5. REGISTRATION, TRANSFER AND EXCHANGE. The Company shall cause to be kept at the Corporate Trust Office of the Trustee or in any office
or agency to be maintained by the Company in accordance with Section 9.2 in a Place of Payment or in such other place or medium as may
be specified pursuant to Section 3.1 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 “Register”)
in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Registered Securities
and the registration of transfers of Registered Securities. The Register shall be in written form or any other form capable of being
converted into written form within a reasonable time. Unless otherwise provided as contemplated by Section 3.1, the Trustee is hereby
appointed “Registrar” for the purpose of registering Registered Securities and transfers of Registered Securities, and for
the purpose of maintaining the Register in respect thereof, as herein provided.

 

Upon
surrender for registration of transfer of any Registered Security of any series at the office or agency maintained pursuant to Section
9.2 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.

 

Unless
otherwise provided as contemplated by Section 3.1, at the option of the Holder, Registered Securities of any series (except a Registered
Security in global form) may be exchanged for other Registered Securities of the same series, of any authorized denominations and of
a like aggregate principal amount containing identical terms and provisions, upon surrender of the Registered Securities to be exchanged
at such office or agency. Whenever any Registered Securities are so surrendered for exchange, the Company shall execute, and the Trustee
shall authenticate and deliver, the Registered Securities which the Holder making the exchange is entitled to receive.

 

Unless
otherwise specified pursuant to Section 3.1 with respect to a series of Securities or as otherwise provided below in this Section 3.5,
owners of beneficial interests in Securities of such series represented by a Security issued in global form will not be entitled to have
Securities of such series registered in their names, will not receive or be entitled to receive physical delivery of Securities of such
series in certificated form and will not be considered the Holders or owners thereof for any purposes hereunder. Notwithstanding any
other provision of this Section, unless and until it is exchanged in whole or in part for Securities in certificated form in the circumstances
described below, a Security in global form representing all or a portion of the Securities of a series may not be transferred or exchanged
except as a whole by the Depository for such series to a nominee of such Depository or by a nominee of such Depository to such Depository
or another nominee of such Depository or by such Depository or any such nominee to a successor Depository for such series or a nominee
of such successor Depository.

 

    22

    

    

 

If
at any time the Depository for the Securities of a series notifies the Company that it is unwilling or unable to continue as Depository
for the Securities of such series or if at any time the Depository for the Securities of such series notifies the Company that it shall
no longer be eligible under Section 3.3, the Company shall appoint a successor Depository with respect to the Securities of such series.
Unless otherwise provided as contemplated by Section 3.1, if a successor Depository for the Securities of such series is not appointed
by the Company within 90 days after the Company receives such notice or becomes aware of such ineligibility, the Company’s election
pursuant to Section 3.1(b) (25) shall no longer be effective with respect to the Securities of such series and the Company shall execute,
and the Trustee, upon receipt of a Company Order for the authentication and delivery of certificated Securities of such series of like
tenor, shall authenticate and deliver, Securities of such series of like tenor in certificated form, in authorized denominations and
in an aggregate principal amount equal to the principal amount of the Security or Securities of such series of like tenor in global form
in exchange for such Security or Securities in global form.

 

The
Company may at any time in its sole discretion determine that Securities of a series issued in global form shall no longer be represented
by such a Security or Securities in global form. In such event the Company shall execute, and the Trustee, upon receipt of a Company
Order for the authentication and delivery of certificated Securities of such series of like tenor, shall authenticate and deliver, Securities
of such series of like tenor in certificated form, in authorized denominations and in an aggregate principal amount equal to the principal
amount of the Security or Securities of such series of like tenor in global form in exchange for such Security or Securities in global
form.

 

If
specified by the Company pursuant to Section 3.1 with respect to a series of Securities, the Depository for such series may surrender
a Security in global form of such series in exchange in whole or in part for Securities of such series in certificated form on such terms
as are acceptable to the Company and such Depository. Thereupon, the Company shall execute, and the Trustee shall authenticate and deliver,
without service charge,

 

(i)
to each Person specified by such Depository a new certificated Security or Securities of the same series of like tenor, of any authorized
denomination as requested by such Person in aggregate principal amount equal to and in exchange for such Person’s beneficial interest
in the Security in global form; and

 

(ii)
to such Depository a new Security in global form of like tenor in a denomination equal to the difference, if any, between the principal
amount of the surrendered Security in global form and the aggregate principal amount of certificated Securities delivered to Holders
thereof.

 

    23

    

    

 

(iii)
Upon the exchange of a Security in global form for Securities in certificated form, such Security in global form shall be cancelled by
the Trustee. Securities in certificated form issued in exchange for a Security in global form pursuant to this Section shall be registered
in such names and in such authorized denominations as the Depository for such Security in global form, pursuant to instructions from
its direct or indirect participants or otherwise, shall instruct the Trustee. The Trustee shall deliver such Securities to the Persons
in whose names such Securities are so registered.

 

Whenever
any Securities are 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.

 

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

 

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

 

Unless
otherwise provided as contemplated by Section 3.1, no service charge shall be made for any registration of transfer or for any 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 or transfer or exchange of Securities, other than exchanges pursuant to Section 3.4 or 10.7 not involving
any transfer.

 

Unless
otherwise provided as contemplated by Section 3.1, none of the Company, the Registrar or the Trustee shall be required (i) to issue,
register the transfer of, or exchange any Securities for a period beginning at the opening of 15 Business Days before any selection for
redemption of Securities of like tenor and of the series of which such Security is a part and ending at the close of business on the
earliest date on which the relevant notice of redemption is deemed to have been given to all Holders of Securities of like tenor and
of such series to be redeemed; or (ii) to register the transfer of or exchange any Registered Security so selected for redemption, in
whole or in part, except the unredeemed portion of any Security being redeemed in part.

 

Section
3.6. REPLACEMENT SECURITIES. If a mutilated Security is surrendered to the Trustee, together with, in proper cases, such security or
indemnity as may be required by the Company or the Trustee to save each of them harmless, the Company shall execute and the Trustee shall
authenticate and deliver a replacement Registered Security, if such surrendered Security was a Registered Security of the same series
and date of maturity.

 

    24

    

    

 

If
there shall be delivered to the Company and the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security
and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in
the absence of notice to the Company or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall
execute and the Trustee shall authenticate and deliver in lieu of any such destroyed, lost or stolen Security a replacement Registered
Security, if such Holder’s claim appertains to a Registered Security, of the same series and principal amount, containing identical
terms and provisions and bearing a number not contemporaneously outstanding.

 

In
case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Company in its discretion
may, instead of issuing a new Security, pay such Security.

 

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

 

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

 

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

 

Section
3.7. PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

 

(a)
Unless otherwise provided as contemplated by Section 3.1, interest, if any, on any Registered Security which is payable, and is punctually
paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name that Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date for such interest at the office or agency maintained for
such purpose pursuant to 9.2; provided, however, that at the option of the Company, interest on any series of Registered Securities that
bear interest may be paid (i) by check mailed to the address of the Person entitled thereto as it shall appear on the Register of Holders
of Securities of such series or (ii) by wire transfer to an account maintained by the Person entitled thereto as specified in the Register
of Holders of Securities of such series.

 

(b)
Unless otherwise provided as contemplated by Section 3.1, any interest on any Registered Security of any series which is payable, but
is not punctually paid or duly provided for, on any interest payment date (herein called “Defaulted Interest”) shall forthwith
cease to be payable to the Holder on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Interest
may be paid by the Company, at its election in each case, as provided in clause (1) or (2) below:

 

    25

    

    

 

(1)
The Company may elect to make payment of any Defaulted Interest to the Persons in whose names such 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 deposit with the Trustee an amount of money equal
to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the trustee
for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons
entitled to such Defaulted Interest as in this clause (1) provided. Thereupon the Trustee shall fix a Special Record Date for the payment
of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and
not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company
of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted
Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to each Holder of such Registered Securities
of such series at his address as it appears in the Register, not less than 10 days prior to such Special Record Date. Notice of the proposed
payment of such Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid
to the Persons in whose names such 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).

 

(2)
The Company may make payment of any Defaulted Interest to the Persons in whose names such Registered Securities of such series (or their
respective Predecessor Securities) are registered at the close of business on a specified date in any other lawful manner not inconsistent
with the requirements of any securities exchange on which such Registered Securities may be listed, and upon such notice as may be required
by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this clause (2), such manner
of payment shall be deemed practicable by the Trustee.

 

(c)
Subject to the foregoing provisions of this Section and Section 3.5, each Security delivered under this Indenture upon registration of
transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue,
which were carried by such other Security.

 

Section
3.8. PERSONS DEEMED OWNERS. Prior to due presentment of any Registered Security for registration of transfer, the Company, the Trustee
and any agent of the Company or the Trustee may treat the Person in whose name such Registered Security is registered as the owner of
such Registered Security for the purpose of receiving payment of principal of, premium, if any, and (subject to Section 3.7) interest
and any other payments on such Registered Security and for all other purposes whatsoever, whether or not such Registered Security shall
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.

 

    26

    

    

 

None
of the Company, the Trustee or any agent of the Company or the Trustee shall have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership interests of a Security in global form, or for maintaining, supervising
or reviewing any records relating to such beneficial ownership interests. Notwithstanding the foregoing, with respect to any Security
in global form, nothing herein shall prevent the Company or 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 (or its nominee), as a Holder, with respect to
such Security in global form or impair, as between such Depository and owners of beneficial interests in such Security in global form,
the operation of customary practices governing the exercise of the rights of such Depository (or its nominee) as Holder of such Security
in global form.

 

Section
3.9. CANCELLATION. The Company at any time may deliver Securities to the Trustee for cancellation. The Registrar and any Paying Agent
shall forward to the Trustee any Securities surrendered to them for replacement, for registration of transfer, or for exchange or payment.
The Trustee shall cancel all Securities surrendered for replacement, for registration of transfer, or for exchange, payment, redemption
or cancellation and may destroy cancelled Securities and, if so destroyed, shall issue a certificate of destruction to the Company. The
Company may not issue new Securities to replace Securities that it has paid or delivered to the Trustee for cancellation.

 

Section
3.10. COMPUTATION OF INTEREST. Except as otherwise specified as contemplated by Section 3.1, interest on the Securities of each series
shall be computed on the basis of a 360-day year of twelve 30-day months.

 

Section
3.11. CURRENCY AND MANNER OF PAYMENT IN RESPECT OF SECURITIES. (a) Unless otherwise specified with respect to any Securities pursuant
to Section 3.1, with respect to Registered Securities of any series payment of the principal of, premium, if any, interest, if any, and
other amounts, if any, on any Registered Security of such series will be made in the currency or currencies or currency unit or units
in which such Registered Security is payable. The provisions of this Section 3.11, including without limitation any defined terms specified
herein, may be modified or superseded in whole or in part pursuant to Section 3.1 with respect to any Securities.

 

(b)
If expressly specified pursuant to Section 3.1, with respect to Registered Securities of any series, Holders shall have the option, subject
to paragraphs (d) and (e) below, to receive payments of principal of, premium, if any, or interest, if any, on such Registered Securities
in any of the currencies or currency units which may be designated for such election by delivering to the Trustee (or the applicable
Paying Agent) a written election with signature guarantees and in the applicable form established pursuant to Section 3.1, not later
than the close of business on the Election Date immediately preceding the applicable payment date. If a Holder so elects to receive such
payments in any such currency or currency unit, such election will remain in effect for such Holder or any transferee of such Holder
until changed by such Holder or such transferee by written notice to the Trustee (or any applicable Paying Agent) for such series of
Registered Securities (but any such change must be made not later than the close of business on the Election Date immediately preceding
the next payment date to be effective for the payment to be made on such payment date, and no such change of election may be made with
respect to payments to be made on any Registered Security of such series with respect to which an Event of Default has occurred or with
respect to which the Company has deposited funds pursuant to Article IV or with respect to which a notice of redemption has been given
by or on behalf of the Company). Any Holder of any such Registered Security who shall not have delivered any such election to the Trustee
(or any applicable Paying Agent) not later than the close of business on the applicable Election Date will be paid the amount due on
the applicable payment date in the relevant currency or currency unit as provided in Section 3.11(a). The Trustee (or the applicable
Paying Agent) shall notify the Company and the Exchange Rate Agent as soon as practicable after the Election Date of the aggregate principal
amount of Registered Securities for which Holders have made such written election.

 

    27

    

    

 

(c)
If the election referred to in paragraph (b) above has been provided for with respect to any Registered Securities of a series pursuant
to Section 3.1, then, unless otherwise specified pursuant to Section 3.1 with respect to any such Registered Securities, not later than
the fourth Business Day after the Election Date for each payment date for such Registered Securities, the Exchange Rate Agent will deliver
to the Company a written notice specifying, in the currency or currencies or currency unit or units in which Registered Securities of
such series are payable, the respective aggregate amounts of principal of, premium, if any, and interest, if any, on such Registered
Securities to be paid on such payment date, and specifying the amounts in such currency or currencies or currency unit or units so payable
in respect of such Registered Securities as to which the Holders of such Registered Securities denominated in any currency or currencies
or currency unit or units shall have elected to be paid in another currency or currency unit as provided in paragraph (b) above. If the
election referred to in paragraph (b) above has been provided for with respect to any Registered Securities of a series pursuant to Section
3.1, and if at least one Holder has made such election, then, unless otherwise specified pursuant to Section 3.1, on the second Business
Day preceding such payment date the Company will deliver to the Trustee (or the applicable Paying Agent) an Exchange Rate Officer’s
Certificate in respect of the Dollar, Foreign Currency or Currencies or other currency unit payments to be made on such payment date.
Unless otherwise specified pursuant to Section 3.1, the Dollar, Foreign Currency or Currencies or other currency unit amount receivable
by Holders of Registered Securities who have elected payment in a currency or currency unit as provided in paragraph (b) above shall
be determined by the Company on the basis of the applicable Market Exchange Rate in effect on the second Business Day (the “Valuation
Date”) immediately preceding each payment date, and such determination shall be conclusive and binding for all purposes, absent
manifest error.

 

(d)
If a Conversion Event occurs with respect to a Foreign Currency or any other currency unit in which Securities of any series are denominated
or payable otherwise than pursuant to an election provided for pursuant to paragraph (b) above, then, unless otherwise specified pursuant
to Section 3.1, with respect to each date for the payment of principal of, premium, if any, and interest, if any, on the applicable Securities
denominated or payable in such Foreign Currency or such other currency unit occurring after the last date on which such Foreign Currency
or such other currency unit was used (the “Conversion Date”), the Dollar shall be the currency of payment for use on each
such payment date (but such Foreign Currency or such other currency unit that was previously the currency of payment shall, at the Company’s
election, resume being the currency of payment on the first such payment date preceded by 15 Business Days during which the circumstances
which gave rise to the Dollar becoming such currency of payment no longer prevail). Unless otherwise specified pursuant to Section 3.1,
the Dollar amount to be paid by the Company to the Trustee or any applicable Paying Agent and by the Trustee or any applicable Paying
Agent to the Holders of such Securities with respect to such payment date shall be, in the case of a Foreign Currency other than a currency
unit, the Dollar Equivalent of the Foreign Currency or, in the case of a Foreign Currency that is a currency unit, the Dollar Equivalent
of the Currency Unit, in each case as determined by the Exchange Rate Agent in the manner provided in paragraph (f) or (g) below.

 

    28

    

    

 

(e)
Unless otherwise specified pursuant to Section 3.1, if the Holder of a Registered Security of a series denominated in any currency or
currency unit shall have elected to be paid in another currency or currency unit or in other currencies as provided in paragraph (b)
above, and (i) a Conversion Event occurs with respect to any such elected currency or currency unit, such Holder shall receive payment
in the currency or currency unit in which payment would have been made in the absence of such election and (ii) if a Conversion Event
occurs with respect to the currency or currency unit in which payment would have been made in the absence of such election, such Holder
shall receive payment in Dollars as provided in paragraph (d) of this Section 3.11 (but, subject to any contravening valid election pursuant
to paragraph (b) above, the elected payment currency or currency unit, in the case of the circumstances described in clause (i) above,
or the payment currency or currency unit in the absence of such election, in the case of the circumstances described in clause (ii) above,
shall, at the Company’s election, resume being the currency or currency unit of payment with respect to Holders who have so elected,
but only with respect to payments on payment dates preceded by 15 Business Days during which the circumstances which gave rise to such
currency or currency unit, in the case of the circumstances described in clause (i) above, or the Dollar, in the case of the circumstances
described in clause (ii) above, becoming the currency or currency unit, as applicable, of payment, no longer prevail).

 

(f)
The “Dollar Equivalent of the Foreign Currency” shall be determined by the Exchange Rate Agent and shall be obtained for
each subsequent payment date by the Exchange Rate Agent by converting the specified Foreign Currency into Dollars at the Market Exchange
Rate on the Conversion Date.

 

(g)
The “Dollar Equivalent of the Currency Unit” shall be determined by the Exchange Rate Agent and, subject to the provisions
of paragraph (h) below, shall be the sum of each amount obtained by converting the Specified Amount of each Component Currency (as each
such term is defined in paragraph (h) below) into Dollars at the Market Exchange Rate for such Component Currency on the Valuation Date
with respect to each payment.

 

(h)
For purposes of this Section 3.11, the following terms shall have the following meanings:

 

A
“Component Currency” shall mean any currency which, on the Conversion Date, was a component currency of the relevant currency
unit.

 

“Conversion
Event” shall mean the cessation of use of (i) a Foreign Currency both by the government of the country which issued such currency
and for the settlement of transactions by a central bank or other public institutions of or within the international banking community,
or (ii) any currency unit for the purposes for which it was established.

 

    29

    

    

 

“Election
Date” shall mean the Regular Record Date for the applicable series of Registered Securities as specified pursuant to Section 3.1
by which the written election referred to in Section 3.11(b) may be made.

 

“Exchange
Rate Agent”, when used with respect to Securities of or within any series, shall mean, unless otherwise specified with respect
to such series of Securities pursuant to Section 3.1, a New York Clearing House bank designated pursuant to Section 3.1 or Section 3.12.

 

“Exchange
Rate Officer’s Certificate” shall mean a certificate setting forth (i) the applicable Market Exchange Rate or the applicable
bid quotation and (ii) the Dollar or Foreign Currency amounts of principal (and premium, if any) and interest, if any (on an aggregate
basis and on the basis of a Security having the lowest denomination principal amount in the relevant currency or currency unit), payable
with respect to a Security of any series on the basis of such Market Exchange Rate or the applicable bid quotation, signed by the President,
the Chief Executive Officer, the Chief Financial Officer, any Vice President, the Treasurer, or any Assistant Treasurer of the Company.

 

“Market
Exchange Rate” shall mean, unless otherwise specified with respect to Securities of any series pursuant to Section 3.1, as of any
date of determination, (i) for any conversion involving a currency unit on the one hand and Dollars or any Foreign Currency on the other,
the exchange rate between the relevant currency unit and Dollars or such Foreign Currency calculated by the method specified pursuant
to Section 3.1 for the Securities of the relevant series, (ii) for any conversion of Dollars into any Foreign Currency, the noon buying
rate for such Foreign Currency for cable transfers quoted in New York City as certified for customs purposes by the Federal Reserve Bank
of New York and (iii) for any conversion of one Foreign Currency into Dollars or another Foreign Currency, the spot rate at noon local
time in the relevant market at which, in accordance with normal banking procedures, the Dollars or Foreign Currency into which conversion
is being made could be purchased with the Foreign Currency from which conversion is being made from major banks located in New York City,
London or any other principal market for Dollars or such purchased Foreign Currency, in each case determined by the Exchange Rate Agent.
Unless otherwise specified with respect to Securities of any series pursuant to Section 3.1, in the event of the unavailability of any
of the exchange rates provided for in the foregoing clauses (i), (ii) and (iii), the Exchange Rate Agent shall use, in its sole discretion
and without liability on its part, such quotation of the Federal Reserve Bank of New York as of the most recent available date, or quotations
from one or more major banks in New York City, London or other principal market for such currency or currency unit in question (which
may include any such bank acting as Trustee under this Indenture), or such other quotations as the Exchange Rate Agent shall deem appropriate.
Unless otherwise specified by the Exchange Rate Agent, if there is more than one market for dealing in any currency or currency unit
by reason of foreign exchange regulations or otherwise, the market to be used in respect of such currency or currency unit shall be that
upon which a nonresident issuer of securities designated in such currency or currency unit would purchase such currency or currency unit
in order to make payments in respect of such securities.

 

    30

    

    

 

A
“Specified Amount” of a Component Currency shall mean the number of units of such Component Currency or fractions thereof
which such Component Currency represented in the relevant currency unit on the Conversion Date. If after the Conversion Date the official
unit of any Component Currency is altered by way of combination or subdivision, the Specified Amount of such Component Currency shall
be divided or multiplied in the same proportion. If after the Conversion Date two or more Component Currencies are consolidated into
a single currency, the respective Specified Amounts of such Component Currencies shall be replaced by an amount in such single currency
equal to the sum of the respective Specified Amounts of such consolidated Component Currencies expressed in such single currency, and
such amount shall thereafter be a Specified Amount and such single currency shall thereafter be a Component Currency. If after the Conversion
Date any Component Currency shall be divided into two or more currencies, the Specified Amount of such Component Currency shall be replaced
by specified amounts of such two or more currencies, the sum of which, at the Market Exchange Rate of such two or more currencies on
the date of such replacement, shall be equal to the Specified Amount of such former Component Currency and such amounts shall thereafter
be Specified Amounts and such currencies shall thereafter be Component Currencies. If, after the Conversion Date of the relevant currency
unit, a Conversion Event (other than any event referred to above in this definition of “Specified Amount”) occurs with respect
to any Component Currency of such currency unit and is continuing on the applicable Valuation Date, the Specified Amount of such Component
Currency shall, for purposes of calculating the Dollar Equivalent of the Currency Unit, be converted into Dollars at the Market Exchange
Rate in effect on the Conversion Date of such Component Currency.

 

All
decisions and determinations of the Exchange Rate Agent regarding the Dollar Equivalent of the Foreign Currency, the Dollar Equivalent
of the Currency Unit, the Market Exchange Rate and changes in the Specified Amounts as specified above with respect to Securities of
any series shall be in its sole discretion and shall, in the absence of manifest error, be conclusive for all purposes and irrevocably
binding upon the Company, the Trustee (and any applicable Paying Agent) and all Holders of Securities of such series denominated or payable
in the relevant currency, currencies or currency units. The Exchange Rate Agent shall promptly give written notice to the Company and
the Trustee of any such decision or determination.

 

In
the event that the Company determines in good faith that a Conversion Event has occurred with respect to a Foreign Currency, the Company
will promptly give written notice thereof to the Trustee (or any applicable Paying Agent) and to the Exchange Rate Agent (and the Trustee
(or such Paying Agent) will promptly thereafter give notice in the manner provided in Section 1.6 to the affected Holders) specifying
the Conversion Date. In the event the Company so determines that a Conversion Event has occurred with respect to any currency unit in
which Securities of a series are denominated or payable, the Company will promptly give written notice thereof to the Trustee (or any
applicable Paying Agent) and to the Exchange Rate Agent (and the Trustee (or such Paying Agent) will promptly thereafter give notice
in the manner provided in Section 1.6 to the affected Holders) specifying the Conversion Date and the Specified Amount of each Component
Currency on the Conversion Date. In the event the Company determines in good faith that any subsequent change in any Component Currency
as set forth in the definition of Specified Amount above has occurred, the Company will similarly give written notice to the Trustee
(or any applicable Paying Agent) and to the Exchange Rate Agent.

 

The
Trustee of the appropriate series of Securities shall be fully justified and protected in relying and acting upon information received
by it from the Company and the Exchange Rate Agent and shall not otherwise have any duty or obligation to determine the accuracy or validity
of such information independent of the Company or the Exchange Rate Agent.

 

    31

    

    

 

Section
3.12. APPOINTMENT AND RESIGNATION OF EXCHANGE RATE AGENT. (a) Unless otherwise specified pursuant to Section 3.1, if and so long as the
Securities of any series (i) are denominated in a currency or currency unit other than Dollars or (ii) may be payable in a currency or
currency unit other than Dollars, or so long as it is required under any other provision of this Indenture, then the Company will maintain
with respect to each such series of Securities, or as so required, at least one Exchange Rate Agent. The Company will cause the Exchange
Rate Agent to make the necessary foreign exchange determinations at the time and in the manner specified pursuant to Section 3.11 for
the purpose of determining the applicable rate of exchange and, if applicable, for the purpose of converting the issued currency or currencies
or currency unit or units into the applicable payment currency or currency unit for the payment of principal, premium, if any, and interest,
if any, pursuant to Section 3.11.

 

(b)
No resignation of the Exchange Rate Agent and no appointment of a successor Exchange Rate Agent pursuant to this Section shall become
effective until the acceptance of appointment by the successor Exchange Rate Agent as evidenced by a written instrument delivered to
the Company and the Trustee of the appropriate series of Securities accepting such appointment executed by the successor Exchange Rate
Agent.

 

(c)
If the Exchange Rate Agent shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of the Exchange
Rate Agent for any cause, with respect to the Securities of one or more series, the Company shall promptly appoint a successor Exchange
Rate Agent or Exchange Rate Agents with respect to the Securities of that or those series (it being understood that any such successor
Exchange Rate Agent may be appointed with respect to the Securities of one or more or all of such series and that, unless otherwise specified
pursuant to Section 3.1, at any time there shall only be one Exchange Rate Agent with respect to the Securities of any particular series
that are originally issued by the Company on the same date and that are initially denominated and/or payable in the same currency or
currencies or currency unit or units).

 

Section
3.13. WIRE TRANSFERS. Notwithstanding any other provisions to the contrary in this Indenture, the Company may make any payment of monies
required to be deposited with the Trustee on account of principal of, or premium, if any, or interest on, Securities of any series (whether
pursuant to optional or mandatory redemption payments, interest payment or otherwise) by wire transfer and immediately available funds
to an account designated by the Trustee on or before the date and time such monies are to be paid to the Holders of the Security of such
series in accordance with the terms hereof.

 

Section
3.14. CUSIP NUMBERS AND ISINS. The Company in issuing Securities may use “CUSIP” numbers or “ISINs”, and if so,
the Trustee may use the CUSIP numbers or ISINs in notices of redemption or exchange as a convenience to Holders; provided, however, that
any such notice may state that no representation is made as to the correctness or accuracy of the CUSIP number or ISIN printed in the
notice or on the Securities, that reliance may be placed only on the other identification numbers printed on the Securities, and any
such redemption or exchange shall not be affected by any defect or omission of such CUSIP numbers or ISINs. The Company will promptly
notify the Trustee of any change in CUSIP numbers or ISINs known to an Officer of the Company.

effect with respect to Securities of or within any series (except as to any surviving rights of registration of transfer or exchange
of such Securities and replacement of such Securities which may have been lost, stolen or mutilated as herein expressly provided for)
and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture
with respect to such Securities when

 

(1)
either

 

(A)
all such Securities previously authenticated and delivered (other than (i) such Securities which have been destroyed, lost or stolen
and which have been replaced or paid as provided in Section 3.6 and (ii) such Securities 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 9.3) have been delivered to the Trustee for cancellation; or

 

(B)
all Securities of such series 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 giving of notice of redemption, 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 or currency unit or units
in which the Securities of such series are payable, sufficient to pay and discharge the entire indebtedness on such Securities not theretofore
delivered to the Trustee for cancellation, for principal, premium, if any, and interest, with respect thereto, to the date of such deposit
(in the case of any such 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 then payable hereunder by the Company; and

 

(3)
the Company has delivered to the Trustee an Officer’s 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.

 

    33

    

    

 

Notwithstanding
the satisfaction and discharge of this Indenture, the obligation of the Company to the Trustee and any predecessor Trustee under Section
6.8 and the obligations of the Company to any Authenticating Agent under Section 6.13 shall survive until the Securities of the discharged
series have been paid in full, and, if money shall have been deposited with the Trustee pursuant to subclause (B) of clause (1) of this
Section, the obligations of the Trustee under Section 4.2 and the last paragraph of Section 9.3 shall survive in accordance with the
terms of such Sections.

 

Section
4.2. APPLICATION OF TRUST FUNDS. Subject to the provisions of the last paragraph of Section 9.3, all money deposited with the Trustee
pursuant to Section 4.1 shall be held in trust and applied by it, in accordance with the provisions of the Securities and this Indenture,

determine, to the Persons entitled thereto, of the principal, premium, if any and any interest for whose payment such money has been
deposited with or received by the Trustee, but such money need not be segregated from other funds except to the extent required by law.

 

Section
4.3. APPLICABILITY OF DEFEASANCE PROVISIONS; COMPANY’S OPTION TO EFFECT DEFEASANCE OR COVENANT DEFEASANCE. Unless pursuant to Section
3.1 provision is made to exclude with respect to the Securities of a particular series either or both of (i) defeasance of the Securities
of or within such series under Section 4.4 or (ii) covenant defeasance of the Securities of or within such series under Section 4.5,
then, in addition to the rights of the Company pursuant to Section 4.1 above, the provisions of such Section or Sections, as the case
may be, together with the provisions of Sections 4.6 through 4.9 inclusive, with such modifications thereto as may be specified pursuant
to Section 3.1 with respect to any Securities of such series, shall be applicable to such Securities and the Company may at its option,
at any time, with respect to such Securities elect to have Section 4.4 (if applicable) or Section 4.5 (if applicable) be applied to such
Outstanding Securities upon compliance with the conditions set forth below in this Article.

 

Section
4.4. DEFEASANCE AND DISCHARGE. Upon the Company’s exercise of the option specified in Section 4.3 applicable to this Section with
respect to the Securities of or within a series, the Company shall be deemed to have been discharged from its obligations with respect
to such Securities on the date the conditions set forth in Section 4.6 are satisfied (hereinafter, a “defeasance”). For this
purpose, such defeasance means that the Company shall be deemed to have paid and discharged the entire indebtedness represented by such
Securities which Securities shall thereafter be deemed to be “Outstanding” only for the purposes of Section 4.7 and the other
Sections of this Indenture referred to in clause (ii) of this Section, and to have satisfied all its other obligations under such Securities
and this Indenture insofar as such Securities are concerned (and the Trustee, at the expense of the Company, shall on Company Order execute
proper instruments acknowledging the same), except the following which shall survive until otherwise terminated or discharged hereunder:
(i) the rights of Holders of such Securities to receive, solely from the trust funds described in Section 4.6(a) and as more fully set
forth in such Section, payments in respect of the principal of, premium, if any, and interest, if any, on such Securities when such payments
are due; (ii) the Company’s obligations with respect to such Securities under Sections 3.5, 3.6, 9.2 and 9.3 and with respect to
the payment of additional amounts, if any, payable with respect to such Securities as specified pursuant to Section 3.1(b) (18); (iii)
the rights, powers, trusts, duties, immunities and indemnities of the Trustee hereunder and (iv) this Article IV. Subject to compliance
with this Article IV, the Company may exercise its option under this Section notwithstanding the prior exercise of its option under Section
4.5 with respect to such Securities. Following a defeasance, payment of such Securities may not be accelerated because of an Event of
Default.

 

    34

    

    

 

Section
4.5. COVENANT DEFEASANCE. Upon the Company’s exercise of the option specified in Section 4.3 applicable to this Section with respect
to any Securities of or within a series, the Company shall be released from its obligations under Sections 7.1, 9.4 and 9.5, and, if
specified pursuant to Section 3.1, its obligations under any other covenant, with respect to such Securities on and after the date the
conditions set forth in Section 4.6 are satisfied (hereinafter, “covenant defeasance”), and such Securities 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 7.1, 9.4 and 9.5, or such other specified covenant, and the operation of
Sections 5.1(3) and 5.1(6), but shall continue to be deemed “Outstanding” for all other purposes hereunder. For this purpose,
such covenant defeasance means that, with respect to such Securities, the Company may omit to comply with and shall have no liability
in respect of any term, condition or limitation set forth in any such Section or such other covenant, whether directly or indirectly,
by reason of any reference elsewhere herein to any such Section or such other covenant or by reason of reference in any such Section
or such other covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default
or an Event of Default under Section 5.1(3) or 5.1(6) or otherwise, as the case may be, but, except as specified above, the remainder
of this Indenture and such Securities shall be unaffected thereby.

 

Section
4.6. CONDITIONS TO DEFEASANCE OR COVENANT DEFEASANCE. The following shall be the conditions to application of Section 4.4 or Section
4.5 to any Securities of or within a series:

 

(a)
The Company shall have deposited or caused to be deposited irrevocably with the Trustee (or another trustee satisfying the requirements
of Section 6.11 who shall agree to comply with, and shall be entitled to the benefits of, the provisions of Sections 4.3 through 4.9
inclusive and the last paragraph of Section 9.3 applicable to the Trustee, for purposes of such Sections also a “Trustee”)

to the Trustee as to the application thereof, (A) money in an amount (in such currency, currencies or currency unit in which such Securities
are then specified as payable at Maturity), or (B) Government Obligations which through the payment of interest and principal in respect
thereof in accordance with their terms will provide, not later than one day before the due date of any payment referred to in clause
(x) or (y) of this Section 4.6(a), money in an amount or (C) a combination thereof in an amount, sufficient, in the determination of
a nationally recognized independent accounting or investment banking firm expressed in a written certification thereof delivered to the
Trustee in the case of clauses (B) or (C), to pay and discharge, and which shall be applied by the Trustee to pay and discharge, (x)
the principal of, premium, if any, and interest, if any, on such Securities on the Maturity of such principal or installment of principal
or interest and (y) any mandatory sinking fund payments applicable to such Securities on the day on which such payments are due and payable
in accordance with the terms of this Indenture and such Securities.

 

    35

or dates in accordance with Article X which shall be given effect in applying the foregoing.

 

(b)
The deposit pursuant to subsection (a) above shall not result in or constitute a Default or Event of Default under this Indenture or
result in a breach or violation of, or constitute a default under, any other material agreement or instrument to which the Company is
a party or by which it is bound.

 

(c)
In the case of an election under Section 4.4, no Default or Event of Default under Section 5.1(4) or 5.1(5) with respect to such Securities
shall have occurred and be continuing during the period commencing on the date of such deposit and ending on the 91st day after such
date (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 4.4, the Company shall have delivered to the Trustee an Officer’s Certificate and an Opinion
of Counsel to the effect 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 Securities 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
and in the same manner and at the same times, as would have been the case if such deposit, defeasance and discharge had not occurred.

 

(e)
In the case of an election under Section 4.5, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that
the Holders of such Securities 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 Officer’s Certificate and an Opinion of Counsel, each stating that all conditions
precedent to the defeasance under Section 4.4 or the covenant defeasance under Section 4.5 (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 4.4 or Section 4.5 (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)
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 as contemplated by Section 3.1.

all money and Government Obligations (or other property as may be provided pursuant to Section 3.1) (including the proceeds thereof)
deposited with the Trustee pursuant to Section 4.6 in respect of any Securities of any series shall be held in trust and applied by the
Trustee, in accordance with the provisions of such Securities and this Indenture, to the payment, either directly or through any Paying
Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Holders of such Securities of all sums
due and to become due thereon in respect of principal, premium, if any, and interest, if any, but such money need not be segregated from
other funds except to the extent required by law.

 

If
specified with respect to a Security of any series pursuant to Section 3.1, if, after a deposit referred to in Section 4.6(a) has been

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
4.6(a) has been made in respect of such Security, or (ii) a Conversion Event occurs as contemplated in Section 3.11(d) or 3.11(e) or
by the terms of the Security in respect of which the deposit pursuant to Section 4.6(a) has been made, the indebtedness represented by
such Security shall be deemed to have been, and will be, fully discharged and satisfied through the payment of the principal of, premium,
if any, and interest, if any, on such Security as the same becomes due out of the proceeds yielded by converting (from time to time as
specified below in the case of any such election) the amount or other property deposited in respect of such Security into the currency
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.

 

Section

The
term “Bankruptcy Law” means Title 11, U.S. Code, or any similar federal or state law for the relief of debtors. The term

Section
5.2. ACCELERATION; RESCISSION AND ANNULMENT. If an Event of Default with respect to the Securities of any series at the time Outstanding
occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of all of the Outstanding Securities
of that series, by written notice to the Company (and, if given by the Holders, to the Trustee), may declare the principal (or, if the
Securities of that series are Original Issue Discount Securities or Indexed Securities, such portion of the principal amount or other
amount as may be specified in the terms of that series) of all the Securities of that series to be due and payable and upon any such
declaration such principal (or, in the case of Original Issue Discount Securities or Indexed Securities, such specified amount) shall
be immediately due and payable.

 

    38

    

    

 

At
any time after such a declaration of acceleration with respect to Securities of any series has been made and before a judgment or decree
for payment of the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of a majority in aggregate
principal amount of the Outstanding Securities of that series, by written notice to the Trustee, may rescind and annul such declaration
and its consequences if all existing Defaults and Events of Default with respect to Securities of that series, other than the non-payment
of the principal of Securities of that series which have become due solely by such declaration of acceleration, have been cured or waived
as provided in Section 5.7. Upon any such rescission, the parties hereto shall be restored respectively to their several positions and
rights hereunder, and all rights, remedies and powers of the parties hereto shall continue as though no acceleration had occurred.

 

Section
5.3. COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY TRUSTEE. The Company covenants that if:

 

(1)
default is made in the payment of any interest on any Security of any series, when such interest becomes due and payable and such default
continues for a period of 30 days, or

 

(2)
default is made in the payment of the principal of (or premium, if any, on) any Security of any series at the Maturity thereof and such
default continues for a period of 10 days,

 

the
Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Securities, the whole amount then due and
payable on such Securities for principal, premium, if any, and interest and, to the extent that payment of such interest shall be legally
enforceable, interest on any overdue principal, premium, if any, and on any overdue interest, at the rate or rates prescribed therefor
in such Securities.

 

If
the Company fails to pay such principal, premium, if any, and interest 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 such principal, premium, if any, and interest
amounts so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company.

 

In
addition, if an Event of Default with respect to Securities of any series occurs and is continuing, the Trustee may in its discretion
proceed, in its own name and as trustee of an express trust, to protect and enforce its rights and the rights of the Holders of Securities
of such series by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights,
whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein,
or to enforce any other proper remedy.

 

Section
5.4. TRUSTEE MAY FILE PROOFS OF CLAIM. The Trustee may file such proofs of claim and other papers or documents as may be necessary or
advisable in order to have the claims of the Trustee and the Holders of Securities of each series allowed in any judicial proceedings
relating to the Company, its creditors or its property.

 

    39

    

    

 

Section
5.5. TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF SECURITIES. All rights of action and claims under this Indenture or the Securities
of any series may be prosecuted and enforced by the Trustee, in its own name and as trustee of an express trust, without the possession
of any of the Securities of such series or the production thereof in any proceeding relating thereto.

 

Section
5.6. DELAY OR OMISSION NOT WAIVER. No delay or omission by the Trustee or any Holder of any Securities to exercise any right or remedy
accruing upon an Event of Default shall impair any such right or remedy or constitute a waiver of or acquiescence in any such Event of
Default.

 

Section
5.7. WAIVER OF PAST DEFAULTS. The Holders of a majority in aggregate principal amount of Outstanding Securities of any series by notice
to the Trustee may waive on behalf of the Holders of all Securities of such series a past Default or Event of Default with respect to
that series and its consequences except a Default or Event of Default (i) in the payment of the principal of, premium, if any, or interest
on any Security of such series or (ii) in respect of a covenant or provision hereof which pursuant to Section 8.2 cannot be amended or
modified without the consent of the Holder of each Outstanding Security of such series adversely affected. Upon any such waiver, such
Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this
Indenture; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon.
In case of any such waiver, the Company, the Trustee and the Holders shall be restored to their former positions and rights hereunder
and under the Securities of such series, respectively.

 

Section
5.8. CONTROL BY MAJORITY. The Holders of a majority in aggregate principal amount of the Outstanding Securities of each series affected
(with each such series voting as a class) 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 it with respect to Securities of that series; provided,
however, that (i) the Trustee may refuse to follow any direction that conflicts with law or this Indenture, (ii) the Trustee may refuse
to follow any direction that is unduly prejudicial to the rights of the Holders of Securities of such series not consenting, or that
would in the good faith judgment of the Trustee have a substantial likelihood of involving the Trustee in personal liability and (iii)
the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction.

 

Section
5.9. LIMITATION ON SUITS BY HOLDERS. No Holder of any Security of any series shall have any right to institute any proceeding, judicial
or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless:

 

(1)
the 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 at least 25% in aggregate principal amount of the Outstanding Securities of that series have made a written request to
the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder;

 

    40

    

    

 

(3)
such Holder or Holders have offered to the Trustee indemnity satisfactory to the Trustee against any loss, liability or expense to be,
or which may be, incurred by the Trustee in pursuing the remedy;

 

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

 

(5)
during such 60 day period, the Holders of a majority in aggregate principal amount of the Outstanding Securities of that series have
not given to the Trustee a direction inconsistent with such written request.

 

No
one or more 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 of such Holders.

 

Section
5.10. RIGHTS OF HOLDERS TO RECEIVE PAYMENT. Notwithstanding any other provision of this Indenture, but subject to Section 9.2, the right
of any Holder of a Security to receive payment of principal of, premium, if any, and, subject to Sections 3.5 and 3.7, interest on the
Security of such Holder, on or after the respective due dates expressed in the Security of such Holder (or, in case of redemption, on
the redemption dates), or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired
or affected without the consent of such Holder.

 

Section
5.11. APPLICATION OF MONEY COLLECTED. If the Trustee collects any money pursuant to this Article with respect to a particular series
of Securities, it shall pay out the money in the following order, at the date or dates fixed by the Trustee and, in case of the distribution
of such money on account of principal, premium, if any, or interest, upon presentation of the Securities of the applicable series and
the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid:

 

First:
to the Trustee for amounts due under Section 6.8 in connection with such series of Securities in respect of which money or other property
is collected;

 

Second:
Subject to the terms of any subordination entered into as contemplated by Section 3.1(b) (27) hereof, to Holders of Securities of such
series in respect of which or for the benefit of which such money has been collected for amounts due and unpaid on such Securities for
principal of, premium, if any, and interest, ratably, without preference or priority of any kind, according to the amounts due and payable
on such Securities for principal, premium, if any, and interest, respectively; and

 

Third:
The balance, if any, to the Company.

 

The
Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section 5.11. At least 15 days before such
record date, the Trustee shall mail to each Holder and the Company a notice that states the record date, the payment date and the amount
to be paid.

 

    41

    

    

 

Unless
otherwise specified in a supplemental indenture with respect to a series of Securities, in any case where Securities of a series are
outstanding which are denominated in more than one currency, or in a composite currency and at least one other currency, and the Trustee
is directed to make ratable payments under this Section to Holders of Securities of such series, the Trustee shall calculate the amount
of such payments as follows: as of the day the Trustee collects an amount under this Article, the Trustee shall, (i) as to each Holder
of a Security of such series to whom an amount is due and payable under this Section which is denominated in a foreign currency or a
composite currency, determine that amount of Dollars that would be obtained for the amount owing such Holder, using the rate of exchange
at which in accordance with normal banking procedures the Trustee could purchase in Dollars as of such day with such amount owing, (ii)
calculate the sum of all Dollar amounts determined under (i) and add thereto any amounts due and payable in Dollars; and (iii) using
the individual amounts determined in (i) or any individual amounts due and payable in Dollars, as the case may be, as a numerator and
the sum calculated in (ii) as a denominator, calculate as to each Holder of a Security of such series to whom an amount is owed under
this Section the fraction of the amount collected under this Article payable to such Holder. Any expenses incurred by the Trustee in
actually converting amounts owing Holders of Securities of a series denominated in a currency or composite currency other than that in
which any amount is collected under this Article shall be likewise (in accordance with this paragraph) be borne ratably by all Holders
of Securities of such series to whom amounts are payable under this Section.

 

Unless
otherwise specified in the supplemental indenture with respect to a series of Securities, to the fullest extent allowed under applicable
law, if for the purpose of obtaining judgment against the Company in any court it is necessary to convert the sum due in respect of the
principal of, or any premium or interest on the Securities of any series (the “Required Currency”) into a currency in which
judgment will be rendered (the “Judgment Currency”), the rate of exchange used shall be the rate at which in accordance with
normal banking procedures the Trustee could purchase in The City of New York the Required Currency with the Judgment Currency on the
New York Business Day preceding that on which final judgment is given. The Company shall not be liable for any shortfall in payments
to Holders of Securities of a series under this Section caused by a change in exchange rates between the time the amount of a judgment
against it is calculated as above and the time the Trustee converts the Judgment Currency into the Required Currency to make payments
under this Section to Holders of such Securities, but payment of such judgment shall discharge all amounts owed by the Company on the
claim or claims underlying such judgment.

 

Section
5.12. RESTORATION OF RIGHTS AND REMEDIES. If the Trustee or any Holder 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, subject to any determination in such proceeding, the Company, the Trustee and the Holders
shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee
and the Holders shall continue as though no such proceeding had been instituted.

 

    42

    

    

 

Section
5.13. RIGHTS AND REMEDIES CUMULATIVE. Except as otherwise provided in Section 5.9 or with respect to the replacement or payment of mutilated,
destroyed, lost or stolen Securities in the last paragraph of Section 3.6, no right or remedy herein conferred upon or reserved to the
Trustee or the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted
by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity
or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion
or employment of any other appropriate right or remedy.

 

Article
VI

THE TRUSTEE

 

Section
6.1. DUTIES AND RESPONSIBILITIES OF TRUSTEE; RELIANCE ON DOCUMENTS, OPINIONS, ETC. (a) The Trustee, prior to the occurrence of an Event
of Default and after the curing or waiver of all Events of Default that may have occurred, undertakes to perform such duties and only
such duties as are specifically set forth in this Indenture. In the event an Event of Default has occurred and is continuing, the Trustee
shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in its exercise,
as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs; provided that if
an Event of Default occurs and is continuing, the Trustee will be under no obligation to exercise any of the rights or powers under this
Indenture at the request or direction of any of the Holders unless such Holders have offered to the Trustee indemnity or security satisfactory
to it in its reasonable discretion against any loss, liability or expense that might be incurred by it in compliance with such request
or direction.

 

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

 

(1)
prior to the occurrence of an Event of Default and after the curing or waiving of all Events of Default that may have occurred:

 

(2)
the duties and obligations of the Trustee shall be determined solely by the express provisions of this Indenture, and the Trustee shall
not be liable except for the performance of such duties and obligations as are specifically set forth in this Indenture and no implied
covenants or obligations shall be read into this Indenture against the Trustee; and

 

(3)
in the absence of bad faith and willful misconduct on the part of the Trustee, the Trustee may conclusively rely, as to the truth of
the statements and the correctness of the opinions expressed therein, upon any 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 that by any provisions hereof
are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether
or not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of any mathematical calculations
or other facts stated therein);

 

    43

    

    

 

(4)
the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer or Officers of the Trustee, unless
it shall be proved that the Trustee was grossly negligent in ascertaining the pertinent facts;

 

(5)
the Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction
of the Holders of not less than a majority of the aggregate principal amount of the Securities at the time outstanding relating to the
time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred
upon the Trustee, under this Indenture;

 

(6)
whether or not therein provided, every provision of this Indenture relating to the conduct or affecting the liability of, or affording
protection to, the Trustee shall be subject to the provisions of this clause (a) and clause (b) below;

 

(7)
the Trustee shall not be liable in respect of any payment (as to the correctness of amount, entitlement to receive or any other matters
relating to payment) or notice effected by the Company or any Paying Agent or any records maintained by any co- Registrar with respect
to the Securities;

 

(8)
if any party fails to deliver a notice relating to an event the fact of which, pursuant to this Indenture, requires notice to be sent
to the Trustee, the Trustee may conclusively rely on its failure to receive such notice as reason to act as if no such event occurred,
unless a Responsible Officer of the Trustee had actual knowledge of such event;

 

(9)
in the absence of written investment direction from the Company, all cash received by the Trustee shall be placed in a non-interest bearing
trust account, and in no event shall the Trustee be liable for the selection of investments or for investment losses incurred thereon
or for losses incurred as a result of the liquidation of any such investment prior to its maturity date or the failure of the party directing
such investments prior to its maturity date or the failure of the party directing such investment to provide timely written investment
direction, and the Trustee shall have no obligation to invest or reinvest any amounts held hereunder in the absence of such written investment
direction from the Company; and

 

(10)
in the event that the Trustee is also acting as custodian, Registrar, Paying Agent, Conversion Agent or transfer agent hereunder, the
rights and protections afforded to the Trustee pursuant to this Article VI shall also be afforded to such custodian, Registrar, Paying
Agent, Conversion Agent or transfer agent.

 

None
of the provisions contained in this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur personal or
financial liability in the performance of any of its duties or in the exercise of any of its rights or powers. The Trustee shall not
be required to give any bond or surety in respect of the performance of its powers or duties hereunder. The Trustee will be under no
obligation to exercise any of its rights and powers under this Indenture at the request or direction of the Holders unless such Holder
has offered to the Trustee security or indemnity satisfactory to it in its reasonable discretion against any loss, liability or expense.

 

    44

    

    

 

(b)
Except as otherwise provided in ‎the foregoing clause (a) of this Section 6.1:

 

(1)
the Trustee may conclusively rely and shall be fully protected in acting upon any resolution, certificate, statement, instrument, opinion,

to have been signed or presented by the proper party or parties;

the Trustee may consult with counsel of its own selection and require an Opinion of Counsel and any advice of such counsel or Opinion
of Counsel shall be full and complete authorization and protection in respect of any action taken or omitted by it hereunder in good
faith and in accordance with such advice or Opinion of Counsel;

 

(4)
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 or other paper or document, but the Trustee,
in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall
determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company,
personally or by agent or attorney at the expense of the Company and shall incur no liability of any kind by reason of such inquiry or
investigation;

 

(5)
the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through a co-trustee,
agents, custodians, nominees or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any
agent, custodian, nominee or attorney appointed by it with due care hereunder;

(8)
the Trustee shall not be responsible for monitoring the performance of other persons or for the failure of others to perform their duties;

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;

 

    45

    

    

 

(11)
the Trustee shall not be required to give any bond or surety in respect of the execution of the trusts and powers under this Indenture;

 

(12)
in no event shall the Trustee be liable for any special, punitive, indirect or consequential loss or damage of any kind whatsoever (including
but not limited to lost profits), even if the Trustee has been advised of the likelihood of such loss or damage and regardless of the
form of action;

 

(13)
the Trustee shall not be charged with knowledge of any Default or Event of Default with respect to the Securities, unless either (1)
a Responsible Officer shall have actual knowledge of such Default or Event of Default or (2) written notice of such Default or Event
of Default shall have been given to the Trustee by the Company or actually received by a Responsible Officer at the Corporate Trust Office
of the Trustee from the Company, a Paying Agent, any Holder or any agent of any Holder, referencing this Indenture;

provisions of this Indenture.

 

Section
6.5. NOTICE OF DEFAULTS. If a Default occurs and is continuing with respect to the Securities of any series and if it is known to a Responsible
Officer of the Trustee, the Trustee shall, within 90 days after it occurs, transmit, in the manner and to the extent provided in Section

that in the case of any default or breach of the character specified in Section 5.1(3) with respect to the Securities of such series,
no such notice to Holders shall be given until at least 90 days after the occurrence thereof.

series as provided in Section 313(c) of the Trust Indenture Act a brief report dated as of such May 15 if required by and in compliance
with Section 313(a) of the Trust Indenture Act. A copy of each report shall, at the time of such transmission to Holders, be filed by

Act, such reports as are required to be filed pursuant to Section 313(b) of the Trust Indenture Act.

 

Section
6.7. SECURITY HOLDER LISTS. The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available
to it of the names and addresses of Holders of Securities of each series. If the Trustee is not the Registrar, the Company shall furnish
to the Trustee semiannually on or before the last day of June and December in each year, and at such other times as the Trustee may request
in writing, a list, in such form and as of such date as the Trustee may reasonably require, containing all the information in the possession
or control of the Registrar, the Company or any of its Paying Agents other than the Trustee as to the names and addresses of Holders

    47

    

    

 

Section
6.8. COMPENSATION AND INDEMNITY. The Company covenants and agrees to pay to the Trustee from time to time, and the Trustee shall be entitled
to, compensation as agreed in writing between the Company and the Trustee for all services rendered by it hereunder in any capacity (which
shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust) as mutually agreed to in
writing between the Trustee and the Company, and the Company will pay or reimburse the Trustee upon its request for all reasonable expenses,
disbursements and advances reasonably incurred or made by the Trustee in accordance with any of the provisions of this Indenture in any
capacity thereunder (including the reasonable compensation and the expenses and disbursements of its agents and counsel and of all Persons
not regularly in its employ and including reasonable attorneys’ fees in connection with enforcement of its rights to indemnity
herein) except any such expense, disbursement or advance as shall have been caused by its gross negligence, willful misconduct or bad
faith. The Company also covenants to indemnify the Trustee in any capacity under this Indenture and any other document or transaction
entered into in connection herewith and its agents and any authenticating agent for, and to hold them harmless against, any loss, claim,
damage, liability, fee, cost, loss, tax, claim, action or expense incurred without gross negligence, willful misconduct or bad faith
on the part of the Trustee, its officers, directors, agents or employees, or such agent or authenticating agent, as the case may be,
and arising out of or in connection with the acceptance or administration of this Indenture or in any other capacity hereunder, including
third-party claims and claims involving the Company, and including the costs and expenses of defending themselves against any claim of
liability in the premises or enforcing this indemnity. The obligations of the Company under this Section 6.8 to compensate or indemnify
the Trustee and to pay or reimburse the Trustee for expenses, disbursements and advances shall be secured by a senior claim to which
the Securities of the applicable series are hereby made subordinate on all money or property held or collected by the Trustee, except,
subject to the effect of Section 5.11, funds held in trust herewith for the benefit of the Holders of particular Securities. The Trustee’s
right to receive payment of any amounts due under this Section 6.8 shall not be subordinate to any other liability or indebtedness of
the Company. The obligation of the Company under this Section 6.8 shall survive the satisfaction and discharge of this Indenture and
the earlier resignation or removal of the Trustee. The Company need not pay for any settlement made without its consent, which consent
shall not be unreasonably withheld. The indemnification provided in this Section 6.8 shall extend to the officers, directors, agents
and employees of the Trustee.

 

Without
prejudice to any other rights available to the Trustee under applicable law, when the Trustee and its agents and any Authenticating Agent
incur expenses or render services after an Event of Default specified in Section 5.1(4) or Section 5.1(5) occurs, the expenses and the
compensation for the services are intended to constitute expenses of administration under any bankruptcy, insolvency or similar laws.

 

    48

    

    

 

Section
6.9. SEPARATE TRUSTEE; REPLACEMENT OF TRUSTEE. (a) The Company may, but need not, appoint a separate Trustee for any one or more series
of Securities. The resignation or removal of the Trustee and the appointment of a successor Trustee shall become effective only upon
the successor Trustee’s acceptance of appointment as provided in Section 6.10. In the event of an appointment of a separate Trustee
for any one or more series of Securities, the allocation of responsibilities between the separate Trustees shall be determined at that
time.

 

(b)
The Trustee may resign at any time with respect to the Securities of any one or more series by giving written notice thereof to the Company.
If the instrument of acceptance by a successor Trustee required by Section 6.10 shall not have been delivered to the Trustee within 30
days after the giving of such notice of resignation, the resigning Trustee may (at the Company’s expense) petition any court of
competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series.

 

(c)
The Holders of a majority in aggregate principal amount of the Outstanding Securities of any series may remove the Trustee with respect
to any one or more series by so notifying the Trustee and the Company in writing and may appoint a successor Trustee for such series
with the Company’s consent.

 

If
an instrument of acceptance by a successor Trustee required by Section 6.10 shall not have been delivered to the Trustee within 30 days
after the giving of such notice of removal, the Trustee being removed may petition any court of competent jurisdiction for the appointment
of a successor Trustee with respect to the Securities of such series.

 

(d)
If at any time:

 

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

 

(2)
the Trustee shall cease to be eligible under Section 6.11 hereof or Section 310(a) of the Trust Indenture Act 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 becomes incapable of acting, is adjudged a bankrupt or an insolvent or a receiver or public officer takes charge of the Trustee
or its property or affairs for the purpose of rehabilitation, conservation or liquidation, then, in any such case, (i) the Company may
remove the Trustee with respect to all Securities, or (ii) subject to Section 315(e) of the Trust Indenture Act, any Holder who has been
a bona fide Holder of a Security for at least six months may, on behalf of himself and all others similarly situated, petition any court
of competent jurisdiction for the removal of the Trustee with respect to Securities of the series held by such Holder and the appointment
of a successor Trustee or Trustees.

 

    49

    

    

 

(e)
If the Trustee resigns or is removed or becomes incapable of acting or if a vacancy exists in the office of Trustee for any reason, with
respect to Securities of one or more series, the Company shall promptly appoint a successor Trustee with respect to the Securities of
that or those series (it being understood that any such successor Trustee may be appointed with respect to the Securities of one or more
or all of such series and that at any time there shall be only one Trustee with respect to the Securities of any particular series) and
shall comply with the applicable requirements of Section 6.10. If, within one year after such resignation, removal or incapability, or
the occurrence of such vacancy, a successor Trustee with respect to the Securities of any series shall be appointed by Act of the Holders
of a majority in principal amount of the Outstanding Securities of such series delivered to the Company and the retiring Trustee, the
successor Trustee so appointed shall, forthwith upon its acceptance of such appointment in accordance with the applicable requirements
of Section 6.10, become the successor Trustee with respect to the Securities of such series and to that extent supersede the successor
Trustee appointed by the Company. If no successor Trustee with respect to the Securities of any series shall have been so appointed by
the Company or the Holders and accepted appointment in the manner required by Section 6.10, then, subject to Section 315(e) of the Trust
Indenture Act, any Holder who has been a bona fide Holder of a Security of such series for at least six months may, on behalf of himself
and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee with respect
to the Securities of such series.

 

Section
6.10. ACCEPTANCE OF APPOINTMENT BY SUCCESSOR. (a) In case of the appointment hereunder of a successor Trustee with respect to Securities
of any series, every such successor Trustee shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument
accepting such appointment. Thereupon, the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee,
without further act, deed or conveyance, shall become vested with all the rights, powers and duties of the retiring Trustee; but, on
the request of the Company or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an
instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer
and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder.

 

(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 such successor Trustee shall execute and deliver an indenture supplemental hereto wherein such successor Trustee
shall accept such appointment and which (i) shall contain such provisions as shall be necessary or desirable to transfer and confirm
to, and to vest in, such 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, (ii) 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 (iii) 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.

 

    50

    

    

 

(c)
No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and
eligible under the Trust Indenture Act.

 

(d)
The Company shall give, or cause to be given, 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 1.6. Each notice shall include the name of the successor Trustee with respect to the Securities
of such series and the address of its Corporate Trust Office.

 

Section
6.11. ELIGIBILITY; DISQUALIFICATION. There shall at all times be a Trustee hereunder with respect to each series of Securities (which
need not be the same Trustee for all series). Each Trustee hereunder shall be eligible to act as trustee under Section 310(a)(1) of the
Trust Indenture Act and shall have a combined capital and surplus of at least $100,000,000. If such corporation 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 such corporation 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.

 

If
the Trustee has or shall acquire a conflicting interest within the meaning of the Trust Indenture Act, the Trustee shall either eliminate
such interest or resign, to the extent and in the manner provided by, and subject to the provisions of, the Trust Indenture Act and this
Indenture.

 

Section
6.12. MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS. Any corporation into which the Trustee may be merged or converted
or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee
shall be a party, or any corporation succeeding to or acquiring 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 shall
have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to, or
by succession to or acquisition of all or substantially all of the corporate trust business of, such authenticating Trustee may adopt
such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated
such Securities.

 

    51

    

    

 

Section
6.13. APPOINTMENT OF AUTHENTICATING AGENT. The Trustee may appoint an Authenticating Agent or Agents with respect to one or more series
of Securities which shall be authorized to act on behalf of the Trustee to authenticate Securities of such series issued upon original
issue exchange, registration of transfer or partial redemption thereof, and Securities so authenticated shall be entitled to the benefits
of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Any such appointment
shall be evidenced by an instrument in writing signed by a Responsible Officer of the Trustee, a copy of which instrument shall be promptly
furnished to the Company. Wherever reference is made in this Indenture to the authentication and delivery of Securities by the Trustee
or the Trustee’s certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf
of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating
Agent. Each Authenticating Agent shall be acceptable to the Company and, except as may otherwise be provided pursuant to Section 3.1,
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 $1,500,000 and subject to supervision or examination by Federal or State authorities.
If such Authenticating Agent publishes reports of condition at least annually, pursuant to law or the requirements of the aforesaid supervising
or examining authority, then for the purposes of this Section, the combined capital and surplus of such Authenticating Agent shall be
deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. In case at any time an
Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, such Authenticating Agent shall resign
immediately in the manner and with the effect specified in this Section.

 

Any
corporation into which an Authenticating Agent may be merged or converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to or
acquiring 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 1.6. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become
vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating
Agent herein. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section.

 

    52

    

    

 

The
Company agrees to pay to each Authenticating Agent from time to time such reasonable compensation as the Company and such Authenticating
Agent agree in writing from time to time including reimbursement of its reasonable expenses for its services under this Section.

 

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

 

This
is one of the [Securities] [of the series designated herein and] referred to in the within-mentioned Indenture.

A

on such matters the Trustee shall be entitled to rely on such evidence as it deems appropriate, which may be or include, without limitation,
reliance solely on an opinion or advice of its counsel.

modified in accordance therewith, and such supplemental indenture shall form a part of this Indenture for all purposes; and every Holder
of Securities of the applicable series theretofore or thereafter authenticated and delivered hereunder and shall be bound thereby; provided
that if such supplemental indenture makes any of the changes described in clauses (1) through (4) of the first proviso to Section 8.2,
such supplemental indenture shall bind each Holder of a Security of the applicable series who has consented to it and every subsequent

by the Company and authenticated and delivered by the Trustee in exchange for Outstanding Securities of such series.

Article

COVENANTS

 

Section
9.1. PAYMENT OF PRINCIPAL, PREMIUM, IF ANY, AND INTEREST. The Company covenants and agrees for the benefit of the Holders of each series
of Securities that it will duly and punctually pay the principal of, premium, if any, and interest on the Securities of that series in
accordance with the terms of the Securities of such series, and this Indenture. An installment of principal, premium, if any, or interest
shall be considered paid on the date it is due if the Trustee or Paying Agent holds on that date money designated for and sufficient
to pay the installment.

 

Section
9.2. MAINTENANCE OF OFFICE OR AGENCY. If Securities of a series are issued as Registered Securities, the Company will maintain in each
Place of Payment for any series of Securities an office or agency where Securities of that series may be presented or surrendered for
payment, where Securities of that series may be surrendered for registration of transfer 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 any 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, and the Company hereby appoints the
Trustee as its agent to receive all such presentations, surrenders, notices and demands (provided, however, that the foregoing appointment
shall not impose or imply any obligation on the part of the Trustee to maintain any office for any such purposes other than the Corporate
Trust Office.)

 

Subject
to the preceding paragraphs, the Company may also from time to time designate one or more other offices or agencies where the Securities
of one or more series may be presented or surrendered for any or all such purposes and may from time to time rescind such designations;
provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office
or agency in each Place of Payment for Securities of any series for such purposes. The Company will 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 as contemplated by Section 3.1, the Trustee shall initially serve as Paying Agent. The Paying Agent may make reasonable
rules not inconsistent herewith for the performance of its functions.

 

Section
9.3. MONEY FOR SECURITIES TO BE HELD IN TRUST; UNCLAIMED MONEY. If the Company shall at any time act as its own Paying Agent with respect
to any series of Securities, it will, on or before each due date of the principal of, premium, if any, or interest on any of the Securities
of that series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay the principal, premium,
if any, or interest so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided and will
promptly notify the Trustee in writing of any failure so to act.

 

    57

    

    

 

Whenever
the Company shall have one or more Paying Agents for any series of Securities, it will, on or prior to each due date of the principal
of or any premium or interest on any Securities of that series, deposit with a Paying Agent a sum sufficient to pay such amount, such
sum to be held as provided by the Trust Indenture Act, and (unless such Paying Agent is the Trustee) the Company will promptly notify
the Trustee of any failure so to act.

 

If
the Company is not acting as its own Paying Agent, the Company will cause each Paying Agent for any series of Securities other than the
Trustee to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions
of this Section, that such Paying Agent will:

 

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

 

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

 

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

 

Notwithstanding
anything in this Section 9.3 to the contrary, the Company may at any time, for the purpose of obtaining the satisfaction and discharge
of this Indenture, or with respect to one or more series of Securities, 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 money.

 

Subject
to applicable abandoned property laws, any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust
for the payment of any principal, premium or interest or other amounts on any Security of any series and remaining unclaimed for two
years after such principal, premium, if any, or interest or other amounts has become due and payable shall be paid to the Company (including
interest income on such funds, if any), or (if then held by the Company) shall be discharged from such trust; and the Holder of such
Security, shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, 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.

 

Section
9.4. CORPORATE EXISTENCE. Subject to Article VII, the Company will at all times do or cause to be done all things necessary to preserve
and keep in full force and effect its corporate existence.

 

Section
9.5. REPORTS BY THE COMPANY. The Company covenants, at any time at which there are Outstanding Securities of any series issued under
this Indenture:

 

    58

    

    

 

(a)
to file with the Trustee, within 30 days after the Company is required to file the same with the Commission, copies of the annual reports
and of the information, documents and other reports (or copies of such portions of any of the foregoing as the Commission may from time
to time by rules and regulations prescribe) which the Company may be required to file with the Commission pursuant to section 13 or section
15(d) of the Securities Exchange Act of 1934, as amended; or, if the Company is not required to file information, documents or reports
pursuant to either of such sections, then to file with the Trustee and the Commission, in accordance with rules and regulations prescribed
from time to time by the Commission, such of the supplementary and periodic information, documents and reports which may be required
pursuant to section 13 of the Securities Exchange Act of 1934, as amended, in respect of a security listed and registered on a national

(c)
to transmit to all Holders of Securities within 30 days after the filing thereof with the Trustee, in the manner and to the extent provided
in section 313(c) of the Trust Indenture Act, such summaries of any information, documents and reports required to be filed by the Company
pursuant to subsections (a) and (b) of this Section 9.5, as may be required by rules and regulations prescribed from time to time by
the Commission.

from the principal executive officer, principal financial officer, or principal accounting officer as to his or her knowledge of whether
the Company is in Default under this Indenture. For purposes of this Section 9.6, such compliance shall be determined without regard
to any period of grace or requirement of notice provided under this Indenture.

REDEMPTION

 

Section
10.1. APPLICABILITY OF ARTICLE. Securities of or within any series which are redeemable in whole or in part before their Stated Maturity
shall be redeemable in accordance with their terms and (except as otherwise specified in the applicable Board Resolution or supplemental
indenture with respect to such series of Securities, as contemplated by Section 3.1 for Securities of any series) in accordance with
this Article.

 

    59

    

    

 

Section
10.2. ELECTION TO REDEEM; NOTICE TO TRUSTEE. The election of the Company to redeem any Securities shall be evidenced by a Board Resolution.
In the case of any redemption at the election of the Company of less than all the Securities of any series of the same tenor, the Company
shall, at least 60 days (45 days in the case of redemption of all Securities of any series or of any series with the same (i) Stated
Maturity, (ii) period or periods within which, price or prices at which and terms and conditions upon which such Securities may or shall
be redeemed or purchased, in whole or in part, at the option of the Company or pursuant to any sinking fund or analogous provision or
repayable at the option of the Holder and (iii) rate or rates at which such Securities bear interest, if any, or formula pursuant to
which such rate or rates accrue (collectively, the “Equivalent Principal Terms”)) prior to the Redemption Date fixed by the
Company (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee of such Redemption Date of the principal amount
of Securities of such series to be redeemed and, if applicable, of the tenor of such Securities to be redeemed. In the case of any redemption
of Securities of a series (i) prior to the expiration of any restriction on such redemption provided in the terms of such Securities
or elsewhere in this Indenture or (ii) pursuant to an election of the Company which is subject to a condition specified in the terms
of such Securities, the Company shall furnish the Trustee with an Officer’s Certificate evidencing compliance with such restriction
or condition.

 

Section
10.3. SELECTION OF SECURITIES TO BE REDEEMED. If less than all the Securities with Equivalent Principal Terms of any series are to be
redeemed (unless all of the Securities of such series and of a specified tenor are to be redeemed), the particular Securities to be redeemed
shall be selected not more than 60 days prior to the Redemption Date by the Trustee, from the Outstanding Securities of such series 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 with Equivalent Principal Terms
or any integral multiple thereof) of the principal amount of Securities of such series with Equivalent Principal Terms of a denomination
larger than the minimum authorized denomination for Securities of that series. Unless otherwise provided in the terms of a particular
series of Securities, the portions of the principal of Securities so selected for partial redemption shall be equal to the minimum authorized
denomination of the Securities of such series, or an integral multiple thereof, and the principal amount which remains outstanding shall
not be less than the minimum authorized denomination for Securities of such series.

 

The
Trustee shall promptly notify the Company in writing of the Securities selected for redemption and, in the case of any Securities selected
for partial redemption, the principal amount thereof to be redeemed. If the Securities of a series having different issue dates, interest
rates and maturities (whether or not originally issued in a Periodic Offering) are to be redeemed, the Company in its discretion may
select the particular Securities or portions thereof to be redeemed and shall notify the Trustee thereof by such time prior to the relevant
redemption date or dates as the Company and the Trustee may agree.

 

For
purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities shall relate,
in the case of any Securities redeemed or to be redeemed only in part, to the portion of the principal amount of such Securities which
has been or is to be redeemed.

 

Section
10.4. NOTICE OF REDEMPTION. Unless otherwise specified as contemplated by Section 3.1, notice of redemption shall be given by first-class
mail, postage prepaid, mailed not less than 30 days nor more than 60 days prior to the Redemption Date, unless a shorter period is specified
in the Securities to be redeemed, to each Holder of the Securities to be redeemed.

 

    60

    

    

 

All
notices of redemption shall state:

 

(1)
the Redemption Date;

 

(2)
the Redemption Price and the amount of accrued interest, if any, to be paid;

 

(3)
if less than all the Outstanding Securities of a series are to be redeemed, the identification (and, in the case of partial redemption
of any Securities, the principal amounts) 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 of such Security will receive, without a charge, a new Security or Securities of authorized
denominations for the principal amount thereof remaining unredeemed;

 

(5)
the Place or Places of Payment where such Securities are to be surrendered for payment for the Redemption Price;

 

(6)
that Securities of the series called for redemption appertaining thereto must be surrendered to the Paying Agent to collect the Redemption
Price;

 

(7)
that, on the Redemption Date, the Redemption Price will become due and payable upon each such Security, or the portion thereof, to be
redeemed and, if applicable, that interest thereon will cease to accrue on and after said date;

 

(8)
that the redemption is for a sinking fund, if such is the case;

 

(9)
the CUSIP number and/or ISIN, if any, of such Securities.

 

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 (provided that the Company prepare and provide to the Trustee the form of
such notice, or, if acceptable to the Trustee, provides sufficient information to enable the Trustee to prepare such notice, in each
case on a timely basis.)

 

Section
10.5. 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, segregate and hold in trust as provided in Section 9.3) an amount of money in
the currency or currencies (including currency units or composite currencies) in which the Securities of such series are payable (except
as otherwise specified pursuant to Section 3.1 for the Securities of such series) sufficient to pay on the Redemption Date the Redemption
Price of, and (unless the Redemption Date shall be an Interest Payment Date) interest accrued to the Redemption Date on, all Securities
or portions thereof which are to be redeemed on that date.

 

    61

    

    

 

Unless
any Security by its terms prohibits any sinking fund payment obligation from being satisfied by delivering and crediting Securities (including
Securities redeemed otherwise than through a sinking fund), the Company may deliver such Securities to the Trustee for crediting against
such payment obligation in accordance with the terms of such Securities and this Indenture.

 

Section
10.6. 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, and from and after such date (unless the Company
shall default in the payment of the Redemption Price and accrued interest) such Securities shall cease to bear interest and such Securities
shall cease from and after the Redemption Date to be entitled to any benefit or security under this Indenture, and the Holders thereof
shall have no right in respect of such Securities except the right to receive the Redemption Price thereof and unpaid interest to the
Redemption Date. Except as provided in the next succeeding paragraph, upon surrender of any such Security for redemption in accordance
with said notice, 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, unless otherwise specified as contemplated by Section 3.1, installments of interest on Registered
Securities whose Stated Maturity is on or prior to the Redemption Date shall be payable to the Holders of such Securities, or one or
more Predecessor Securities, registered as such at the close of business on the relevant Record Dates according to their terms and the
provisions of Section 3.7.

 

If
any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal (and premium, if any) shall,
until paid, bear interest from the Redemption Date at the rate prescribed therefor in such Security.

 

Section
10.7. SECURITIES REDEEMED IN PART. Upon surrender of a Security that is redeemed only in part at any Place of Payment therefor (with,
if the Company or the Trustee so require, 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), the Company shall execute and the Trustee
shall authenticate and deliver to the Holder of that Security, without service charge, a new Security or Securities of the same series,
having the same form, terms and Stated Maturity, in any authorized denomination equal in aggregate principal amount to the unredeemed
portion of the principal amount of the Security surrendered.

 

Article
XI

SINKING FUNDS

 

Section
11.1. APPLICABILITY OF ARTICLE. The provisions of this Article shall be applicable to any sinking fund for the retirement of Securities
of a series except as otherwise specified as contemplated by Section 3.1 for Securities of such series.

 

    62

    

    

 

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 Securities of any series is
herein referred to as an “optional sinking fund payment.” If provided for by the terms of Securities of any series, the cash
amount of any sinking fund payment may be subject to reduction as provided in Section 11.2. Each sinking fund payment shall be applied
to the redemption of Securities of any series as provided for by the terms of Securities of such series.

 

Section
11.2. SATISFACTION OF SINKING FUND PAYMENTS WITH SECURITIES. The Company (i) may deliver Outstanding Securities of a series (other than
any previously called for redemption) and (ii) may apply as a credit Securities of a series which have been redeemed either at the election
of the Company pursuant to the terms of such Securities or through the application of permitted optional sinking fund payments pursuant
to the terms of such Securities, in each case in satisfaction of all or any part of any sinking fund payment with respect to the Securities
of such series required to be made pursuant to the terms of such Securities as provided for by the terms of such series; provided that
such Securities have not been previously so credited. Such Securities shall be received and credited for such purpose by the Trustee
at the Redemption Price specified in such Securities for redemption through operation of the sinking fund and the amount of such sinking
fund payment shall be reduced accordingly.

 

Section
11.3. REDEMPTION OF SECURITIES FOR SINKING FUND. Not less than 60 days prior to each sinking fund payment date for any series of Securities,
the Company will deliver to the Trustee an Officer’s Certificate specifying the amount of the next ensuing sinking fund payment
for that series pursuant to the terms of that series, the portion thereof, if any, which is to be satisfied by payment of cash and the
portion thereof, if any, which is to be satisfied by delivering and crediting Securities of that series pursuant to Section 11.2 and
will also deliver to the Trustee any Securities to be so delivered. Not less than 30 days before each such sinking fund payment date
the Trustee shall select the Securities to be redeemed upon such sinking fund payment date in the manner specified in Section 10.3 and
cause notice of the redemption thereof to be given in the name of and at the expense of the Company in the manner provided in Section
10.4. Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated in
Sections 10.6 and 10.7.

 

This
Indenture may be executed in any number of counterparts, each of which shall be an original, but such counterparts shall together constitute
but one instrument.

DESCRIPTION
OF SECURITIES

 

General

 

Abri
SPAC I, Inc. has authorized stock consisting of 100,000,000 shares of Common Stock, par value $0.0001, and 1,000,000 shares of preferred
stock, par value $0.0001. As of the date of this report, 7,461,998 shares of Common Stock are issued and outstanding. No preferred shares
are issued or outstanding. The following description summarizes the material terms of our securities. Because it is only a summary, it
may not contain all the information that is important to you. For a complete description you should refer to our Certificate of Incorporation,
bylaws, our warrant agreement, and to the applicable provisions of Delaware law.

 

Units

 

Each
Unit consists of one share of common stock and one redeemable warrant. Each redeemable warrant entitles the registered holder to purchase
one share of common stock at a price of $11.50 per share and shall expire five years after the completion of an initial business combination,
or earlier upon redemption. Fractional shares will either be rounded down to the nearest whole share or otherwise addressed in accordance
with the applicable provisions of Delaware Law. On September 3, 2021, the holders of the Units
were able to elect to separately trade the shares of Common Stock and Warrants included in the Units.

 

Common
Stock

 

Our
stockholders of record are entitled to one vote for each share held on all matters to be voted on by stockholders. In connection with
any vote held to approve our initial business combination, our Sponsor, as well as all of our officers and directors, have agreed to
vote their respective shares of Common Stock owned by them immediately prior to this offering and any shares purchased in this offering
or following this offering in the open market, including any shares included in shares of Common Stock acquired in this offering or in
the aftermarket, in favor of the proposed business combination.

 

We
will consummate our initial business combination only if we have net tangible assets of at least $5,000,001 either immediately prior
to or upon such consummation and, solely if a vote is held to approve a business combination, a majority of the outstanding shares of
Common Stock voted are voted in favor of the business combination.

 

The
Board is divided into three classes, each of which will generally serve for a term of three years with only one class of directors being
elected in each year. There is no cumulative voting with respect to the election of directors, with the result that the holders of more
than 50% of the shares eligible to vote for the election of directors can elect all of the directors.

 

Pursuant
to our Certificate of Incorporation, if we do not consummate an initial business combination within 12 months from the closing of the
IPO, or August 12, 2022 (or February 12, 2023 in the event ABRI extends the time to complete a business combination), our corporate existence
will cease except for the purposes of winding up our affairs and liquidating. If we are forced to liquidate prior to an initial business
combination, our public stockholders are entitled to share ratably in the Trust Account, based on the amount then held in the Trust Account.
Our Sponsor, officers and directors have agreed to waive their rights to participate in any liquidation distribution from the Trust Account
occurring upon our failure to consummate an initial business combination with respect to the founder’s Common Stock and Private
shares of Common Stock. Our Sponsor, officers and directors will therefore not participate in any liquidation distribution from the trust
account with respect to such shares or shares of Common Stock. They will, however, participate in any liquidation distribution from the
trust account with respect to any shares of Common Stock acquired in, or following, the IPO.

 

     

     

    

 

Our
stockholders have no conversion, preemptive or other subscription rights and there are no sinking fund or redemption provisions applicable
to the shares of Common Stock, except that public stockholders have the right to sell their shares of Common Stock to us in a tender
offer or have their shares of Common Stock converted to cash equal to their pro rata share of the trust account in connection with the
consummation of our initial business combination. Public stockholders who redeem their shares of Common Stock into their share of the
Trust Account still have the right to exercise any Warrants they still hold outside of such shares of Common Stock but will forfeit,
without the receipt of any additional consideration, the portion of the Warrant included in the shares of Common Stock. Accordingly,
an investor may have a disincentive to exercise redemption rights due to the loss of such portion of the Warrants.

 

Preferred
Stock

 

There
are no shares of preferred stock outstanding. Our Certificate of Incorporation as of the date of this prospectus/proxy statement/consent
solicitation statement authorizes the issuance of 1,000,000 shares of preferred stock with such designation, rights and preferences as
may be determined from time to time by the Board. Accordingly, the Board is empowered, without stockholder approval, to issue preferred
stock with dividend, liquidation, conversion, voting or other rights which could adversely affect the voting power or other rights of
the holders of Common Stock. However, the underwriting agreement prohibits us, prior to a business combination, from issuing preferred
stock which participates in any manner in the proceeds of the Trust Account, or which votes as a class with the Common Stock on a business
combination. We may issue some or all of the preferred stock to effect a business combination. In addition, the preferred stock could
be utilized as a method of discouraging, delaying or preventing a change in control of us. Although we do not currently intend to issue
any shares of preferred stock, we cannot assure you that we will not do so in the future.

 

Redeemable
Warrants

 

No
warrants are currently outstanding. Each redeemable warrant entitles the registered holder to purchase one share of common stock at a
price of $11.50 per share, subject to adjustment as discussed below, at any time commencing on the later of the completion of our initial
business combination and one year from the consummation of this offering. Except as set forth below, no warrants will be exercisable
for cash unless we have an effective and current registration statement covering the shares of common stock issuable upon exercise of
the warrants and a current prospectus relating to such shares. Notwithstanding the foregoing, if a registration statement covering the
shares of common stock issuable upon exercise of the warrants is not effective within 90 days from the consummation of our initial
business combination, warrant holders may, until such time as there is an effective registration statement and during any period when
we shall have failed to maintain an effective registration statement, exercise warrants on a cashless basis pursuant to the exemption
from registration provided by Section 3(a)(9) of the Securities Act provided that such exemption is available. If an exemption from
registration is not available, holders will not be able to exercise their warrants on a cashless basis. The warrants will expire five
years after the completion of an initial business combination at 5:00 p.m., Eastern Standard Time.

 

In
addition, if (x) we issue additional shares of common stock or equity-linked securities for capital raising purposes in connection
with the closing of our initial business combination at an issue price or effective issue price of less than $9.50 per share (with such
issue price or effective issue price to be determined in good faith by our board of directors), (y) the aggregate gross proceeds
from such issuances represent more than 60% of the total equity proceeds, and interest thereon, available for the funding of our initial
business combination, and (z) the volume weighted average trading price of our shares of common stock during the 20 trading day
period starting on the trading day prior to the day on which we consummate our initial business combination (such price, the “Market Price”)
is below $9.50 per share, the exercise price of the warrants will be adjusted (to the nearest cent) to be equal to 115% of the Market
Price, and the $16.50 per share redemption trigger price described above will be adjusted (to the nearest cent) to be equal to 165% of
the Market Price.

 

    2

     

    

 

We
may call the warrants for redemption, in whole and not in part, at a price of $0.01 per warrant:

 

		●	at any time while the warrants are exercisable,

 

		●	upon not less than 30 days’ prior written notice
of redemption to each warrant holder,

 

		●	if, and only if, the reported last sale price of the shares
of common stock equals or exceeds $16.50 per share, for any 20 trading days within a 30 trading day period ending on the third business
day prior to the notice of redemption to warrant holders (the “Force-Call Provision”), and

 

		●	if, and only if, there is a current registration statement
in effect with respect to the shares of common stock underlying such warrants at the time of redemption and for the entire 30-day trading
period referred to above and continuing each day thereafter until the date of redemption.

 

The
right to exercise will be forfeited unless the warrants are exercised prior to the date specified in the notice of redemption. On and
after the redemption date, a record holder of a warrant will have no further rights except to receive the redemption price for such holder’s
warrant upon surrender of such warrant.

 

The
redemption criteria for our warrants have been established at a price which is intended to provide warrant holders a reasonable premium
to the initial exercise price and provide a sufficient differential between the then-prevailing share price and the warrant exercise
price so that if the share price declines as a result of our redemption call, the redemption will not cause the share price to drop below
the exercise price of the warrants.

 

If
we call the warrants for redemption as described above, our management will have the option to require all holders that wish to exercise
warrants to do so on a “cashless basis.” In such event, each holder would pay the exercise price by surrendering the whole
warrants for that number of shares of common stock equal to the quotient obtained by dividing (x) the product of the number of shares
of common stock underlying the warrants, multiplied by the difference between the exercise price of the warrants and the “fair
market value” (defined below) by (y) the fair market value. The “fair market value” shall mean the volume weighted
average price of the shares of common stock for the 20 trading days ending on the third trading day prior to the date on which the notice
of redemption is sent to the holders of warrants. Whether we will exercise our option to require all holders to exercise their warrants
on a “cashless basis” will depend on a variety of factors including the price of our shares of common stock at the time the
warrants are called for redemption, our cash needs at such time and concerns regarding dilutive share issuances.

 

The
warrants will be issued in registered form under a warrant agreement between Continental Stock Transfer & Trust Company, as
warrant agent, and us. The warrant agreement provides that the terms of the warrants may be amended without the consent of any holder
to cure any ambiguity or correct any defective provision, but requires the approval, by written consent or vote, of the holders of a
majority of the then outstanding warrants in order to make any change that adversely affects the interests of the registered holders.

 

The
exercise price and number of shares of common stock issuable on exercise of the warrants may be adjusted in certain circumstances including
in the event of a share capitalizations, extraordinary dividend or our recapitalization, reorganization, merger or consolidation. However,
the warrants will not be adjusted for issuances of shares of common stock at a price below their respective exercise prices.

 

The
warrants may be exercised upon surrender of the warrant certificate on or prior to the expiration date at the offices of the warrant
agent, with the exercise form on the reverse side of the warrant certificate completed and executed as indicated, accompanied by full
payment of the exercise price, by certified or official bank check payable to us, for the number of warrants being exercised. The warrant
holders do not have the rights or privileges of holders of shares of common stock and any voting rights until they exercise their warrants
and receive shares of common stock. After the issuance of shares of common stock upon exercise of the warrants, each holder will be entitled
to one vote for each share held of record on all matters to be voted on by stockholders.

 

    3

     

    

 

Except
as described above, no warrants will be exercisable and we will not be obligated to issue shares of common stock unless at the time a
holder seeks to exercise such warrant, a prospectus relating to the shares of common stock issuable upon exercise of the warrants is
current and the shares of common stock have been registered or qualified or deemed to be exempt under the securities laws of the
state of residence of the holder of the warrants. Under the terms of the warrant agreement, we have agreed to use our best efforts to
meet these conditions and to maintain a current prospectus relating to the shares of common stock issuable upon exercise of the warrants
until the expiration of the warrants. However, we cannot assure you that we will be able to do so and, if we do not maintain a current
prospectus relating to the shares of common stock issuable upon exercise of the warrants, holders will be unable to exercise their warrants
and we will not be required to settle any such warrant exercise. If the prospectus relating to the shares of common stock issuable upon
the exercise of the warrants is not current or if the shares of common stock is not qualified or exempt from qualification in the jurisdictions
in which the holders of the warrants reside, we will not be required to net cash settle or cash settle the warrant exercise, the warrants
may have no value, the market for the warrants may be limited and the warrants may expire worthless.

 

Warrant
holders may elect to be subject to a restriction on the exercise of their warrants such that an electing warrant holder (and his, her
or its affiliates) would not be able to exercise their warrants to the extent that, after giving effect to such exercise, such holder
(and his, her or its affiliates) would beneficially own in excess of 9.99% of the shares of common stock issued and outstanding. Notwithstanding
the foregoing, any person who acquires a warrant with the purpose or effect of changing or influencing the control of our company, or
in connection with or as a participant in any transaction having such purpose or effect, immediately upon such acquisition will be deemed
to be the beneficial owner of the underlying shares of common stock and not be able to take advantage of this provision.

 

No
fractional shares will be issued upon exercise of the warrants. If, upon exercise of the warrants, a holder would be entitled to receive
a fractional interest in a share (as a result of a subsequent share capitalizations payable in shares of common stock, or by a split
up of the shares of common stock or other similar event), we will, upon exercise, round up or down to the nearest whole number the number
of shares of common stock to be issued to the warrant holder.

 

Private
Units

 

Except
as described below, the private units have terms and provisions that are identical to those the units in this offering. The private units
(including their component securities and the common stock issuable upon exercise of the private warrants included in the private units)
will not be transferable, assignable or salable until 30 days after the completion of our initial business combination (except pursuant
to limited exceptions as described under “Principal Stockholders — Transfers of Founder Shares and Private Units,”
to our officers and directors and other persons or entities affiliated with the initial purchasers of the private units). The private
warrants so long as they are held by our sponsor or its permitted transferees a) will not be redeemable by us and b) will be exercisable
on a cashless basis. If the private warrants are held by holders other than our sponsor or its permitted transferees, the private warrants
will be redeemable by us in all redemption scenarios and exercisable by the holders on the same basis as the warrants included in the
units being sold in this offering. 

 

We
expect to have policies in place that restrict insiders from selling our securities except during specific periods of time. Even during
such periods of time when insiders will be permitted to sell our securities, an insider cannot trade in our securities if he or she is
in possession of material non-public information. Accordingly, unlike public stockholders who could exercise their warrants and
sell the common stock received upon such exercise freely in the open market in order to recoup the cost of such exercise, the insiders
could be significantly restricted from selling such securities. As a result, we believe that allowing the holders to exercise such warrants
on a cashless basis is appropriate. 

 

In
order to meet our working capital needs following the consummation of this offering, our insiders, officers and directors may, but are
not obligated to, loan us funds, from time to time or at any time, in whatever amount they deem reasonable in their sole discretion.
Each loan would be evidenced by a promissory note. The notes would either be paid upon consummation of our initial business combination,
without interest, or, at the lender’s discretion, up to $1,500,000 of the notes may be converted upon consummation of our business
combination into additional units at a price of $10.00 per unit. These units would be identical to the private units.

 

Dividends

 

We
have not paid any cash dividends on our common stock to date and do not intend to pay cash dividends prior to the completion of a business
combination. The payment of cash dividends in the future will be dependent upon our revenues and earnings, if any, capital requirements
and general financial condition subsequent to completion of a business combination. The payment of any cash dividends subsequent to a
business combination will be within the discretion of our board of directors at such time. In addition, our board of directors is
not currently contemplating and does not anticipate declaring any stock dividends in the foreseeable future. Further, if we incur any
indebtedness, our ability to declare dividends may be limited by restrictive covenants we may agree to in connection therewith.

 

    4

     

    

 

Certain
Anti-Takeover Provisions of Delaware Law and our Certificate of Incorporation and By-Laws

 

We
will be subject to the provisions of Section 203 of Delaware General Corporation Law, or the DGCL, regulating corporate takeovers. This
statute prevents certain Delaware corporations, under certain circumstances, from engaging in a “business combination” with:

 

		●	a stockholder who owns 10% or more of our outstanding voting
stock (otherwise known as an “interested stockholder”);

 

		●	an affiliate of an interested stockholder; or

 

		●	an associate of an interested stockholder, for three years
following the date that the stockholder became an interested stockholder.

 

A
“business combination” includes a merger or sale of more than 10% of our assets. However, the above provisions of Section
203 do not apply if:

 

		●	our board of directors approves the transaction that made
the stockholder an “interested stockholder,” prior to the date of the transaction;

 

		●	after the completion of the transaction that resulted in
the stockholder becoming an interested stockholder, that stockholder owned at least 85% of our voting stock outstanding at the time the
transaction commenced, other than statutorily excluded shares of common stock; or

 

		●	on or subsequent to the date of the transaction, the business

Staggered
board of directors

 

Our
certificate of incorporation provides that our board of directors will be classified into three classes of directors. As a result, in
most circumstances, a person can gain control of our board only by successfully engaging in a proxy contest at two or more annual meetings.

 

Special
meeting of stockholders

 

Our
bylaws provide that special meetings of our stockholders may be called only by resolution of the board of directors, or by the Chief
Executive Officer.
