of this Indenture, the Company shall furnish to the Trustee such certificates and opinions as may be required under the Trust

statement that each individual signing such certificate or opinion has read such covenant or condition and the definitions herein
relating thereto;

of Holders; Record Dates. Any request, demand, authorization, direction, notice, consent, waiver or other action provided
or permitted by this Indenture to be given, made 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. 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 (subject to Section 6.01) conclusive in favor of the Trustee and the Company, if made in the manner provided in this
Section.

 

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.

 

    	-8-

    	 

    

 

The principal amount
and serial numbers of Securities held by any Person, and the date of holding the same, shall be proved by the Security Register.

 

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.

 

The Company may set any
day as a record date for the purpose of determining the Holders of Outstanding Securities of any series entitled to give, make
or take any request, demand, authorization, direction, notice, consent, waiver or other action provided or permitted by this Indenture
to be given, made or taken by Holders of Securities of such series, provided, that the Company may not set a record date
for, and the provisions of this paragraph shall not apply with respect to, the giving or making of any notice, declaration, request
or direction referred to in the next paragraph. If any record date is set pursuant to this paragraph, the Holders of Outstanding
Securities of the relevant series on such record date, and no other Holders, shall be entitled to take the relevant action, whether
or not such Holders remain Holders after such record date; provided, that no such action shall be effective hereunder unless
taken on or prior to the applicable Expiration Date by Holders of the requisite principal 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 principal amount of Outstanding Securities of the
relevant 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 of the relevant series in the manner set forth in Section
1.06.

 

The Trustee may set any
day as a record date for the purpose of determining the Holders of Outstanding Securities of any series entitled to join in the
giving or making of (i) any Notice of Default, (ii) any declaration of acceleration referred to in Section 5.02, (iii) any
request to institute proceedings referred to in Section 5.07(2) or (iv) any direction referred to in Section 5.12,
in each case with respect to Securities of such series. If any record date is set pursuant to this paragraph, the Holders of Outstanding
Securities of such series on such record date, and no other Holders, shall be entitled to join in such notice, declaration, request
or direction, whether or not such Holders remain Holders after such record date; provided, that no such action shall be
effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of
Outstanding Securities of such series on such record date. Nothing in this paragraph shall be construed to prevent the Trustee
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 principal amount of Outstanding
Securities of the relevant series on the date such action is taken. Promptly after any record date is set pursuant to this paragraph,
the Trustee, at the Company’s expense, shall cause notice of such record date, the proposed action by Holders and the applicable
Expiration Date to be given to the Company in writing and to each Holder of Securities of the relevant series in the manner set
forth in Section 1.06.

 

    	-9-

    	 

    

 

With respect to any record
date set pursuant to this Section, the party hereto that sets such record date may designate any day 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 other party hereto in writing, and
to each Holder of Securities of the relevant series in the manner set forth in Section 1.06, on or prior to the existing
Expiration Date. If an Expiration Date is not designated with respect to any record date set pursuant to this Section, the party
hereto that set such record date 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.

 

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.

 

Without limiting the
generality of the foregoing, a Holder, including a Depositary that is the Holder of a Global Security, may make, give or take,
by a proxy or proxies duly appointed in writing, any request, demand, authorization, direction, notice, consent, waiver or other
action provided in this Indenture to be made, given or taken by Holders, and a Depositary that is the Holder of a Global Security
may provide its proxy or proxies to the beneficial owners of interests in any such Global Security through such Depositary’s
standing instructions and customary practices.

 

Section 1.05.     Notices,
Etc., to Trustee and Company. Any request, demand, authorization, direction, notice, consent, waiver or Act of Holders or
other document provided or permitted by this Indenture to be made upon, given or furnished to, or filed with,

 

(1)         the
Trustee by any Holder or by the Company shall be sufficient for every purpose hereunder if made, given, furnished or filed in writing
(which may be via facsimile) to or with the Trustee at its Corporate Trust Office, Attention: Corporate Trust Services, or

 

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

 

Section 1.06.     Notice
to Holders; Waiver. Except as otherwise expressly provided herein, where this Indenture provides for notice of any event to
Holders of Securities, such notice shall be sufficiently given to Holders of Securities if in writing and mailed, first-class postage
prepaid, to each Holder of a Security affected by such event, at the address of such Holder as it appears in the Security Register,
not later than the latest date (if any), and not earlier than the earliest date (if any), prescribed for the giving of such notice.

 

    	-10-

    	 

    

 

In case by reason of
the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice to Holders
of Securities by mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification
for every purpose hereunder. In any case where notice to Holders of Securities is given by mail, neither the failure to mail such
notice, nor any defect in any notice so mailed, to any particular Holder of a Security shall affect the sufficiency of such notice
with respect to other Holders.

 

Where this Indenture
provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice either before
or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders of Securities 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 1.07.     Conflict
with Trust Indenture Act. This Indenture shall incorporate and be governed by the provisions of the Trust Indenture Act that
are required to be part of and to govern indentures qualified under the Trust Indenture Act. If any provision hereof limits, qualifies
or conflicts with a provision of the Trust Indenture Act that is required under the Trust Indenture Act to be a part of and govern
this Indenture, 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.

 

Section 1.08.     Effect
of 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 1.09.     Successors
and Assigns. All covenants and agreements in this Indenture by the Company shall bind its successors and assigns, whether
so expressed or not.

 

Section 1.10.     Separability
Clause. In case any provision in this Indenture or in the 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 1.11.     Benefits
of Indenture. Nothing in this Indenture or in the Securities, express or implied, shall give to any Person, other than the
parties hereto and their successors hereunder, the Holders of Securities, any benefit or any legal or equitable right, remedy
or claim under this Indenture.

 

Section 1.12.     Governing
Law. This Indenture and the Securities shall be governed by and construed in accordance with the law of the State of New York.

 

    	-11-

    	 

    

 

Section 1.13.     Legal
Holidays. In any case where any Interest Payment Date, Redemption Date, sinking fund payment date, Stated Maturity or Maturity
of any Security shall not be a Business Day at any Place of Payment, then (notwithstanding any other provision of this Indenture
or of the Securities (other than a provision of any Security which specifically states that such provision shall apply in lieu
of this Section)) payment of interest or principal (and premium, if any) 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 the
Interest Payment Date, Redemption Date or sinking fund payment date or at the Stated Maturity or Maturity, as the case may be.

 

Section 1.14.     Language
of Notices, Etc. 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.

 

Section 1.15.     Submission
to Jurisdiction. The Company irrevocably submits to the non-exclusive jurisdiction of any federal or state court in the City,
County and State of New York and any appellate court from any thereof, in any legal suit, action or proceeding based on or arising
under the Securities or this Indenture and agrees that all claims in respect of such suit or proceeding may be determined in any
such court. The Company irrevocably waives, to the fullest extent permitted by law, any objection to any such suit, action or
proceeding in such courts, whether on the grounds of venue, residence or domicile or the defense of an inconvenient forum or objections
to personal jurisdiction with respect to the maintenance of such legal suit, action or proceeding. The Company agrees that the
final judgment in any such suit, action or proceeding brought in such court shall be conclusive and binding upon the Company and
may be enforced in any court to the jurisdiction of which the Company is subject by a suit upon such judgment.

 

Section 1.16.     U.S.A.
Patriot Act. The parties hereto acknowledge that in accordance with Section 326 of the U.S.A. Patriot Act, the Trustee, like
all financial institutions and in order to help fight the funding of terrorism and money laundering, is required to obtain, verify,
and record information that identifies each person or legal entity that establishes a relationship or opens an account with the
Trustee. The parties to this Indenture agree that they will provide the Trustee with such information as it may reasonably request
in order for the Trustee to satisfy the requirements of the U.S.A. Patriot Act.

 

Section 1.17.     Force
Majeure. In no event shall the Trustee be responsible or liable for any failure or delay in the performance of its obligations
hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including, without limitation, strikes,
work stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of
God, and interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services; it being
understood that the Trustee shall use reasonable efforts which are consistent with accepted practices in the banking industry
to resume performance as soon as practicable under the circumstances.

 

Section 1.18.     Waiver
of Jury Trial. EACH OF THE COMPANY AND THE TRUSTEE 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.

in Global Form. If Securities of or within a series are issuable in global form, as specified as contemplated by Section
3.01, then, notwithstanding Clause (3) of Section 3.01 and the provisions of Section 3.02, any such Security
shall represent such of the Outstanding Securities of such series as shall be specified therein and may provide that it shall
represent the aggregate amount of Outstanding Securities from time to time endorsed thereon and that the aggregate amount of Outstanding
Securities represented thereby may from time to time be reduced to reflect exchanges. Any endorsement of a Security in global

any instructions 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 with Section 1.02 and need not be accompanied by an Opinion of Counsel.

 

The provisions of the
last sentence of Section 3.03 shall apply to any Security represented by a Security in global form if such Security was
never issued and sold by the Company and the Company delivers to the Trustee the Security in global form together with written
instructions (which need not comply with Section 1.02 and need not be accompanied by an Opinion of Counsel) with regard
to the reduction in the principal amount of Securities represented thereby, together with the written statement contemplated by
the last sentence of Section 3.03.

 

Notwithstanding the provisions

in the name or names of Persons other than the Depositary for such Global Security or a nominee thereof;

 

(25)        the
appointment of any paying agents, authenticating agents, transfer agents, registrars or other agents, if other than the Trustee;

 

(26)        the
Person to whom any interest on any Security of the series shall be payable, if other than 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, and
the extent to which, or the manner in which, any interest payable on a temporary global Security on an Interest Payment Date will
be paid, if other than in the manner provided in Section 3.04;

 

(27)        if
the principal amount payable at the Stated Maturity of any Securities of the series will not be determinable as of any one or more
dates prior to the Stated Maturity, the amount which shall be deemed to be the principal amount of such Securities as of any such
date for any purpose thereunder or hereunder, including the principal amount thereof which shall be due and payable upon any Maturity
other than the Stated Maturity or which shall be deemed to be Outstanding as of any date prior to the Stated Maturity (or, in any
such case, the manner in which such amount deemed to be the principal amount shall be determined);

 

    	-17-

    	 

    

  

(28)        whether,
under what circumstances and the Currency in which the Company will pay additional amounts as contemplated by Section 10.09
on the Securities of the series to any Holder who is not a United States Person(s) (including any modification to the definition
of such term) in respect of any tax, assessment or governmental charge and, if so, whether the Company will have the option to
redeem such Securities rather than pay such additional amounts (and the terms of any such option);

 

(29)        any
other terms of the series (which terms shall not be inconsistent with the provisions of this Indenture, except as permitted by
Section 9.01(5)).

 

All Securities of such
series shall be substantially identical except as to denomination and except as may otherwise be provided in or pursuant to the
Board Resolution referred to above and (subject to Section 3.03) set forth, or determined in the manner provided, in the
Officers’ Certificate referred to above or in any such indenture supplemental hereto.

 

If any of the terms of
the series are established by action taken pursuant to a Board Resolution, a copy of an appropriate record of such action shall
be certified by the Secretary or an Assistant Secretary of the Company and delivered to the Trustee at or prior to the delivery
of the Officers’ Certificate setting forth the terms of the series.

 

Section 3.02.     Denominations.
Unless otherwise provided as contemplated by Section 3.01 with respect to the Securities of any series, any Securities
of such series, other than Securities issued in global form (which may be of any denomination), shall be issuable in denominations
of $2,000 and integral multiples of $1,000 in excess thereof.

 

Section 3.03.     Execution,
Authentication, Delivery and Dating. The Securities shall be executed on behalf of the Company by its Chief Executive Officer,
its Chief Financial Officer, its President or one of its Vice Presidents, attested by its Secretary or one of its Assistant Secretaries.
The signature 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 after the execution and delivery of this Indenture, 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. If the forms or terms of the
Securities of the series have been established by or pursuant to one or more Board Resolutions as permitted by Sections 2.01
and 3.01, 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 6.01) shall be fully protected in
relying upon, an Opinion of Counsel stating,

 

    	-18-

    	 

    

  

(1)         if
the forms of such Securities have been established by or pursuant to Board Resolution as permitted by Section 2.01, that
such form have been established in conformity with the provisions of this Indenture;

 

(2)         if
the terms of such Securities have been established by or pursuant to Board Resolution as permitted by Section 3.01, that
such terms have been established in conformity with the provisions of this Indenture; and

 

(3)         that
such Securities when authenticated and delivered by the Trustee and issued by the Company in the manner and subject to any conditions
specified in such Opinion of Counsel, will constitute valid and legally binding obligations of the Company enforceable in accordance
with their terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general
applicability relating to or affecting creditors’ rights and to general equity principles.

 

If such form or terms
have been so established, the Trustee shall not be required to authenticate such Securities if the issue of such Securities pursuant
to this Indenture will affect the Trustee’s own rights, duties or immunities under the Securities and this Indenture or otherwise
in a manner that is not reasonably acceptable to the Trustee.

 

Notwithstanding the provisions
of Section 3.01 and of the two preceding paragraphs, if all Securities of a series are not to be originally issued at one
time, it shall not be necessary to deliver the Officers’ Certificate otherwise required pursuant to Section 3.01 or
the Company Order and Opinion of Counsel otherwise required pursuant to such preceding paragraphs at or prior to the authentication
of each Security of such series if such documents are delivered at or prior to the authentication upon original issuance of the
first Security of such series to be issued.

 

Each Security shall be
dated the date of its authentication.

 

No Security shall be
entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein executed by the Trustee by manual signature, and such
certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated
and delivered hereunder. 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 3.09, for all purposes of this Indenture such Security shall be deemed never to have been authenticated and delivered
hereunder and shall never be entitled to the benefits of this Indenture.

 

Section
3.04.     Temporary Securities. Pending the preparation of definitive
Securities of any series, the Company may execute, and upon Company Order the Trustee shall authenticate and deliver,
temporary Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized
denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued and with such
appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may
determine, as evidenced by their execution of such Securities.

 

    	-19-

    	 

    

 

If temporary Securities
of any series are issued, the Company will cause definitive Securities of that series to be prepared without unreasonable delay.
After the preparation of definitive Securities of that series, the temporary Securities of such series shall be exchangeable for
definitive Securities of such series upon surrender of the temporary Securities of such series at the office or agency of the Company
in a Place of Payment for that series, without charge to the Holder. Upon surrender for cancellation of any one or more temporary
Securities of any series the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor one or more
definitive Securities of the same series, of any authorized denominations and like aggregate principal amount and tenor.

 

Until exchanged in full
as hereinafter provided, the temporary Securities of any series shall in all respects be entitled to the same benefits under this
Indenture as definitive Securities of the same series and of like tenor authenticated and delivered hereunder.

 

Section 3.05.     Registration,
Registration of Transfer and Exchange. The Company shall cause to be kept at an office or agency to be maintained by the Company
in accordance with Section 10.02 a register (being the combined register of the Security Registrar and all transfer agents
designated pursuant to Section 10.02 for the purpose of registration of transfer of Securities and sometimes collectively
referred to as the “Security Register”) in which, subject to such reasonable regulations as it may prescribe,
the Company shall provide for the registration of Securities and the registration of transfers of Securities. The Trustee is hereby
appointed “Security Registrar” for the purpose of registering Securities and transfers of Securities
as herein provided.

 

Upon surrender for registration
of transfer of any Security of a series at the office or agency of the Company maintained pursuant to Section 10.02 for
such purpose 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 Securities of the same series, of any authorized denominations
and of like tenor and aggregate principal amount.

 

At the option of the
Holder, Securities of any series may be exchanged for other Securities of the same series, of any authorized denominations and
of like tenor and aggregate principal amount, upon surrender of the Securities to be exchanged at such office or agency. Whenever
any Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the
Securities that the Holder making the exchange is entitled to receive.

 

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

 

    	-20-

    	 

    

 

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

 

No service charge shall
be made for any registration of transfer or exchange of Securities, but the Company may require payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities,
other than exchanges pursuant to Section 3.04, 9.06 or 11.07 not involving any transfer.

 

If the Securities of
any series (or of any series and specified tenor) are to be redeemed in part, the Company shall not be required (A) to issue, register
the transfer of or exchange any Securities of that series (or of that series and specified tenor, as the case may be) during a
period beginning at the opening of business 15 days before any selection of Securities of that series to be redeemed and ending
at the close of business on the day of the mailing of the relevant notice of redemption or (B) to register the transfer of or exchange
any Security so selected for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part.

 

The Trustee shall have
no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture
or under applicable law with respect to any transfer of any interest in any Security other than to require delivery of such certificates
and other documentation or evidence as are expressly required by, and to do so if and when expressly required by, the terms of
this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

 

Section 3.06.     Mutilated,
Destroyed, Lost and Stolen Securities. If any mutilated Security is surrendered to the Trustee, the Company shall execute
and the Trustee shall authenticate and deliver in exchange therefor a new Security of the same series and of like tenor and principal
amount and bearing a number not contemporaneously outstanding.

 

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 new Security of the same
series and of like tenor and principal amount and bearing a number not contemporaneously outstanding.

 

Notwithstanding the provisions
of the previous two paragraphs, 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) connected
therewith.

 

    	-21-

    	 

    

  

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 3.07.     Payment
of Interest; Interest Rights Preserved. Except as otherwise provided as contemplated by Section 3.01 with respect to
any series of Securities, interest on any 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.

 

Any interest on any 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:

 

(1)         The
Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Securities of such series (or their
respective Predecessor Securities) are registered at the close of business on a Special Record Date for the payment of such Defaulted
Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted
Interest proposed to be paid on each Security of such series and the date of the proposed payment, and at the same time 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 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 given to each Holder of Securities of such series in the manner set forth in Section 1.06, 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 the 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).

 

    	-22-

    	 

    

  

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

 

Subject to the foregoing
provisions of this Section and Section 3.05, each Security delivered under this Indenture upon registration of transfer
of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which
were carried by such other Security.

 

Section 3.08.     Persons
Deemed Owners. Prior to due presentment of a 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 Security is registered as the owner of such Security for
the purpose of receiving payment of principal of and any premium and (subject to Section 3.05 and Section 3.07)
any interest on such Security and for all other purposes whatsoever, whether or not such Security be overdue, and neither the
Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary.

 

Section 3.09.     Cancellation.
All Securities surrendered for payment, redemption, registration of transfer or exchange or for credit against any sinking fund
payment shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be promptly cancelled
by it. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered
hereunder which the Company may have acquired in any manner whatsoever, and may deliver to the Trustee (or to any other Person
for delivery to the Trustee) for cancellation any Securities previously authenticated hereunder which the Company has not issued
and sold, and all Securities so delivered shall be promptly cancelled by the Trustee. No Securities shall be authenticated in
lieu of or in exchange for any Securities cancelled as provided in this Section, except as expressly permitted by this Indenture.
All cancelled Securities held by the Trustee shall be disposed of in the customary manner of the Trustee.

 

Section 3.10.     Computation
of Interest. Except as otherwise specified as contemplated by Section 3.01 for Securities of any series, 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.     CUSIP
Numbers. The Company in issuing the Securities may use “CUSIP” numbers (if then generally in use), and, if so,
the Trustee shall use such “CUSIP” numbers in notices of redemption as a convenience to Holders; provided that
any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities
or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed
on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company will
notify the Trustee of any change to the “CUSIP” numbers.

amounts, as provided in Section 10.09), and the Trustee, at the expense of the Company, shall execute proper instruments

amount sufficient to pay and discharge the entire indebtedness on such Securities not theretofore delivered to the Trustee for
cancellation, for principal and any premium and interest to the date of such deposit (in the case of Securities which have become
due and payable) or to the Stated Maturity or Redemption Date, as the case may be;

 

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

 

(3)         the

    	-24-

    	 

    

  

Notwithstanding the satisfaction
and discharge of this Indenture, the obligations of the Company to the Trustee under Section 6.07, the obligations of the
Trustee to any Authenticating Agent under Section 6.14 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 4.02 and the last paragraph
of Section 10.03 shall survive such satisfaction and discharge.

 

Section 4.02.     Application
of Trust Money. Subject to the provisions of the last paragraph of Section 10.03, all money deposited with the Trustee
pursuant to Section 4.01 shall be held in trust and applied by it, in accordance with the provisions of the 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 Persons entitled thereto, of the principal and any premium and interest for the payment
of which such money has been deposited with the Trustee.

any one of the following events (whatever the reason for such Event of Default and whether it shall be occasioned by the provisions
of Article XIV or be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or

included in this Indenture solely for the benefit of series of Securities other than that series), and continuance of such default
or breach for a period of 90 days after there has been given, by registered or certified mail, to the Company by the Trustee or
to the Company and the Trustee by the Holders of at least 25% in principal amount of the Outstanding Securities of that series
a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a “Notice
of Default” hereunder or

 

    	-25-

    	 

    

  

(5)         the
entry by a court having jurisdiction in the premises of (A) a decree or order for relief in respect of the Company in an involuntary

or any such other decree or order unstayed and in effect for a period of 60 consecutive days;

 

(6)         the
commencement by the Company of a voluntary case or proceeding under any applicable Federal or State bankruptcy, insolvency, reorganization
or other similar law or of any other case or proceeding to be adjudicated a bankrupt or insolvent, of the consent by it to the
entry of a decree or order for relief in respect of the Company in an involuntary case or proceeding under any applicable Federal

to pay its debts generally as they become due, or the taking of corporate action by the Company in furtherance of any such action;
or

 

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

 

Section 5.02.     Acceleration
of Maturity; Rescission and Annulment. If an Event of Default (other than an Event of Default specified in Section 5.01(5)
or 5.01(6)) with respect to Securities of any series at the time Outstanding occurs and is continuing, then in every
such case the Trustee or the Holders of not less than 25% in principal amount of the Outstanding Securities of that series may
declare the principal amount of all the Securities of that series (or, if any Securities of that series are Original Issue Discount
Securities, such portion of the principal amount of such Securities as may be specified by the terms thereof) to be due and payable
immediately, by a notice in writing to the Company (and to the Trustee if given by Holders), and upon any such declaration such
principal amount (or specified amount) shall become immediately due and payable. If an Event of Default specified in Section
5.01(5) or 5.01(6)) with respect to Securities of any series at the time Outstanding occurs, the principal amount of
all the Securities of that series (or, if any Securities of that series are Original Issue Discount Securities, such portion of
the principal amount of such Securities as may be specified by the terms thereof) shall automatically, and without any declaration
or other action on the part of the Trustee or any Holder, become immediately due and payable.

 

    	-26-

    	 

    

 

At any time after such
a declaration of acceleration with respect to Securities of any series has been made and before a judgment or decree for payment
of the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of a majority in principal
amount of the Outstanding Securities of that series, by written notice to the Company and the Trustee, may rescind and annul such
declaration and its consequences if

 

(1)            the
Company has paid or deposited with the Trustee a sum sufficient to pay

 

(A)         all
overdue interest on all Securities of that series,

 

(B)         the
principal of (and premium, if any, on) any Securities of that series which have become due otherwise than by such declaration of
acceleration and any interest thereon at the rate or rates prescribed therefor in such Securities,

 

(C)         to
the extent that payment of such interest is lawful, interest upon overdue interest at the rate or rates prescribed therefor in
such Securities, and

 

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

 

and

 

(2)           all
Events of Default with respect to Securities of that series, other than the 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 5.13.

 

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

 

Section 5.03.     Collection
of Indebtedness and Suits for Enforcement by Trustee. The Company covenants that if

 

(1)         default
is made in the payment of any interest on any Security 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 at the Maturity thereof, in the case of technical
or administrative difficulties only if such a default persists for a period of five 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 and any premium and interest and, to the extent that payment of such interest shall be legally enforceable,
interest on any overdue principal and premium and on any overdue interest, at the rate or rates prescribed therefor in such Securities,
and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the
owed compensation, expenses, disbursements, indemnities and advances, of the Trustee, its agents and counsel.

 

    	-27-

    	 

    

 

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

 

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

 

Section 5.04.         Trustee
May File Proofs of Claim. In case of any judicial proceeding relative to the Company (or any other obligor upon the Securities),
its property or its creditors, the Trustee shall be entitled and empowered, by intervention in such proceeding or otherwise, to
take any and all actions authorized under the Trust Indenture Act in order to have claims of the Holders and the Trustee allowed
in any such proceeding. In particular, the Trustee shall be authorized to collect and receive any moneys or other property payable
or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator
or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee
and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee
any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel,
and any other amounts due the Trustee under Section 6.07.

 

No provision of this
Indenture shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan
of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof or to authorize
the Trustee to vote in respect of the claim of any Holder in any such proceeding; provided, however, that the Trustee
may, on behalf of the Holders, vote for the election of a trustee in bankruptcy or similar official and be a member of a creditors’
or other similar committee.

 

Section 5.05.         Trustee
May Enforce Claims Without Possession of Securities. All rights of action and claims under this Indenture or the Securities
may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the production thereof in any
proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of
an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Securities
in respect of which such judgment has been recovered.

the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal or any premium or
interest, upon presentation of the Securities and the notation thereon of the payment if only partially paid and upon surrender
thereof if fully paid:

 

FIRST: To the payment
of all amounts due the Trustee under Section 6.07;

 

SECOND: To the payment
of the amounts then due and unpaid for principal of and any premium and interest on the Securities in respect of which or for the
benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due

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

 

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

 

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

 

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

 

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

 

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

 

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

 

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

Section 5.08.         Unconditional
Right of Holders to Receive Principal, Premium and Interest. Notwithstanding any other provision in this Indenture, the Holder
of any Security shall have the right, which is absolute and unconditional, to receive payment of the principal of and any premium
and (subject to Sections 3.05 and 3.07) interest on such Security on the respective Stated Maturities expressed
in such Security (or, in the case of redemption, on the Redemption Date) and to institute suit for the enforcement of any such
payment, and such rights shall not be impaired without the consent of such Holder.

 

Section 5.09.         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.

 

Section 5.10.         Rights
and Remedies Cumulative. Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed,
lost or stolen Securities in the last paragraph of Section 3.06, no right or remedy herein conferred upon or reserved to
the Trustee or to 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.

 

Section 5.11.         Delay
or Omission Not Waiver. No delay or omission of the Trustee or of any Holder of any Securities to exercise any right or remedy
accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or
an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised
from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be.

 

Section 5.12.         Control
by Holders. The Holders of a majority in principal amount of the Outstanding Securities of any series shall have the right
to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust
or power conferred on the Trustee, with respect to the Securities of such series, provided that

 

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

 

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

 

Section 5.13.         Waiver
of Past Defaults. The Holders of not less than a majority in principal amount of the Outstanding Securities of any series
may on behalf of the Holders of all the Securities of such series waive any past default hereunder with respect to such series
and its consequences, except a default

 

    	-30-

    	 

    

 

(1)         in
the payment of the principal of or any premium or interest on any Security of such series, or

 

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

 

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

 

Section 5.14.         Undertaking
for Costs. In any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee
for any action taken, suffered or omitted by it as Trustee, a court may require any party litigant in such suit to file an undertaking
to pay the costs of such suit, and may assess costs including reasonable attorneys’ fees and expenses against any such party
litigant, in the manner and to the extent provided in the Trust Indenture Act; provided that neither this Section nor the
Trust Indenture Act shall be deemed to authorize any court to require such an undertaking or to make such an assessment in any
suit instituted by the Company or the Trustee.

 

Section 5.15.         Waiver
of Usury, Stay or Extension Laws. The Company covenants (to the extent that it may lawfully do so) that it will not at any
time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any usury, stay or extension
law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture;
and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and
covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and
permit the execution of every such power as though no such law had been enacted.

or performance of any of its powers or duties hereunder.

 

Section 6.08.         Conflicting

capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee with respect
to the Securities of any series 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.

 

    	-34-

    	 

    

 

Section 6.10.         Resignation
and Removal; Appointment of Successor. No resignation or removal of the Trustee and no appointment of a successor Trustee
pursuant to this Article shall become effective until the acceptance of appointment by the successor Trustee in accordance with
the applicable requirements of Section 6.11. The Trustee may resign at any time with respect to the Securities of one or
more series by giving written notice thereof to the Company. If the instrument of acceptance by a successor Trustee required by
Section 6.11 shall not have been delivered to the Trustee within 30 days after the giving of such notice of resignation,
the resigning Trustee may petition any court of competent jurisdiction for the appointment of a successor Trustee with respect
to the Securities of such series.

 

The Trustee may be removed
at any time with respect to the Securities of any series by Act of the Holders of a majority in principal amount of the Outstanding
Securities of such series, delivered to the Trustee and to the Company.

 

If at any time:

 

(1)         the
Trustee shall fail to comply with Section 6.08 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 6.09 and shall fail to resign after written request therefor by the Company
or by any such Holder, or

 

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

 

then, in any such case,
(A) the Company by a Board Resolution may remove the Trustee with respect to all Securities, or (B) subject to Section 5.14,
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 all Securities and the appointment
of a successor Trustee or Trustees.

 

If the Trustee shall
resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any cause, with respect
to the Securities of one or more series, the Company, by a Board Resolution, shall promptly appoint a successor Trustee or Trustees
with respect to the Securities of that or those series (it being understood that any such successor Trustee may be appointed with
respect to the Securities of one or more or all of such series and that at any time there shall be only one Trustee with respect
to the Securities of any particular series) and shall comply with the applicable requirements of Section 6.11. 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 6.11, become the successor
Trustee with respect to the Securities of such series and to that extent supersede the successor Trustee appointed by the Company.
If no successor Trustee with respect to the Securities of any series shall have been so appointed by the Company or the Holders
of Securities of such series and accepted appointment in the manner required by Section 6.11, any Holder who has been
a bona tide 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.

 

    	-35-

    	 

    

 

The Company shall give
notice of each resignation and each removal of the Trustee with respect to the Securities of any series and each appointment of
a successor Trustee with respect to the Securities of any series to all Holders of Securities of such series in the manner provided
in Section 1.06. 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.         Acceptance
of Appointment by Successor. In case of the appointment hereunder of a successor Trustee with respect to all Securities, every
such successor Trustee so appointed shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument
accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor
Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the
retiring Trustee; but, on 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.

 

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

 

    	-36-

    	 

    

 

Upon request of any such
successor Trustee, the Company shall execute any and all instruments for more fully and certainly vesting in and confirming to
such successor Trustee all such rights, powers and trusts referred to in the first or second preceding paragraph, as the case may
be.

 

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

 

Section 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 all or substantially all 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 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.

 

Section 6.13.         Preferential
Collection of Claims Against Company. If and when the Trustee shall be or become a creditor of the Company (or any other obligor
upon the Securities), the Trustee shall be subject to the provisions of Section 311 of the Trust Indenture Act, but only to the
extent therein specified, regarding the collection of claims against the Company (or any such other obligor). For purposes of
Section 311(b)(4) and (6) of such Act, the following terms shall mean:

 

(i)          “cash
transaction” means any transaction in which full payment for goods or securities sold is made within seven days after
delivery of the goods or securities in currency or in checks or other orders drawn upon banks or bankers and payable upon demand;
and

 

(ii)         “self-liquidating
paper” means any draft, bill of exchange, acceptance or obligation which is made, drawn, negotiated or incurred by
the Company for the purpose of financing the purchase, processing, manufacturing, shipment, storage or sale of goods, wares or
merchandise and which is secured by documents evidencing title to, possession of, or a lien upon, the goods, wares or merchandise
or the receivables or proceeds arising from the sale of the goods, wares or merchandise previously constituting the security, provided
the security is received by the Trustee simultaneously with the creation of the creditor relationship with the Company arising
from the making, drawing, negotiating or incurring of the draft, bill of exchange, acceptance or obligation.

Section 6.14.         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
and upon exchange, registration of transfer or partial redemption thereof or pursuant to Section 3.06, 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, and a copy of such evidence shall be promptly furnished to the Company. Wherever reference is made in this Indenture
to the authentication and delivery of Securities by the Trustee or the Trustee’s certificate of authentication, such reference
shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of
authentication executed on behalf of the Trustee by an Authenticating Agent. Each Authenticating Agent shall be acceptable to
the Company and shall at all times be a corporation organized and doing business under the laws of the United States of America,
any State thereof or the District of Columbia, authorized under such laws to act as Authenticating Agent, having a combined capital
and surplus of not less than $50,000,000 and subject to supervision or examination by Federal or State authority. If such Authenticating
Agent publishes reports of condition at least annually, pursuant to law or to the requirements of said 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. If 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

such corporation shall be otherwise eligible under this Section, without the execution or filing of any paper or any further act
on the part of the Trustee or the Authenticating Agent.

 

An Authenticating Agent
may resign at any time by giving written notice thereof to the Trustee and to the Company. The Trustee may at any time terminate
the agency of an Authenticating Agent by giving written notice thereof 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

	 	As Trustee
	 	 
	 	By:

If all of the Securities
of a series may not be originally issued at one time, and if the Trustee does not have an office capable of authenticating Securities
upon original issuance located in a Place of Payment where the Company wishes to have Securities of such series authenticated upon
original issuance, the Trustee, if so requested by the Company in writing (which writing need not comply with Section 1.02
and need not be accompanied by an Opinion of Counsel), shall appoint in accordance with this Section an Authenticating Agent having
an office in a Place of Payment designated by the Company with respect to such series of Securities.

of that series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay the principal
and any premium or interest so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided
and will promptly notify the Trustee of its action or failure so to act.

 

Whenever the Company
shall have one or more Paying Agents for any series of Securities, it will, 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 the principal and any premium
or interest so becoming due, such sum to be held in trust for the benefit of the Persons entitled to such principal, premium or
interest, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of its action or failure so
to act.

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) comply

for payment in respect of the Securities of that series.

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

 

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

Subsidiary to be maintained and kept in good condition, repair and working order and supplied with all necessary equipment and
will cause to be made all necessary repairs, renewals, replacements, betterments and improvements thereof, all as in the judgment
of the Company may be necessary so that the business carried on in connection therewith may be properly and advantageously conducted
at all times; provided, however, that nothing in this Section shall prevent the Company from discontinuing the operation
or maintenance of any of such properties if such discontinuance is, in the judgment of the Company, desirable in the conduct of
its business or the business of any Subsidiary and not disadvantageous in any material respect to the ability of the Company to
make payments hereunder.

whose amount, applicability or validity is being contested in good faith.

of Certain Covenants. Except as otherwise specified as contemplated by Section 3.01 for Securities of such series,
the Company may, with respect to the Securities of any series, omit in any particular instance to comply with any term, provision
or condition set forth in any covenant provided pursuant to Section 3.01(12), 9.01(2) or 9.01(7) for the
benefit of the Holders of such series if before the time for such compliance the Holders of at least 50% in principal amount of
the Outstanding Securities of such series shall, by Act of such Holders, either waive such compliance in such instance or generally
waive compliance with such term, provision or condition, but no such waiver shall extend to or affect such term, provision or
condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company
and the duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect.

Section 10.09.         Additional

any Security of such series additional amounts as provided therein. Whenever in this Indenture there is mentioned, in any context,
the payment of the principal of or any premium or interest on, or in respect of, any Security of any series or the net proceeds
received on the sale or exchange of any Security of any series, such mention shall be deemed to include mention of the payment
of additional amounts provided for in this Section to the extent that, in such context, additional amounts are, were or would
be payable in respect thereof pursuant to the provisions of this Section and express mention of the payment of additional amounts
(if applicable) in any provisions hereof shall not be construed as excluding additional amounts in those provisions hereof where
such express mention is not made.

REDEMPTION OF SECURITIES

 

Section 11.01.         Applicability
of Article. Securities of any series which are redeemable before their Stated Maturity shall be redeemable in accordance with
their terms and (except as otherwise specified as contemplated by Section 3.01 for such Securities) in accordance with
this Article.

 

Section 11.02.         Election
to Redeem; Notice to Trustee. In case of any redemption at the election of the Company of less than all the Securities of
any series (including any such redemption affecting only a single Security), the Company shall, at least 60 days prior to the
Redemption Date fixed by the Company (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee of such
Redemption Date, of the principal amount of Securities of such series to be redeemed and, if applicable, of the tenor of the Securities
to be redeemed (unless all of the Securities of a specified tenor are to be redeemed). In the case of any redemption of Securities
(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 Officers’ Certificate evidencing compliance with such restriction or condition.

 

Section 11.03.         Selection
by Trustee of Securities to Be Redeemed. If less than all the Securities of any series are to be redeemed (unless all the
Securities of such series and of a specified tenor are to be redeemed or unless such redemption affects only a single Security),
the particular Securities to be redeemed shall be selected not more than 35 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 is in accordance with the
procedures of the Depositary and which may provide for the selection for redemption of portions (equal to the minimum authorized
denomination for Securities of that series or any integral multiple thereof) of the principal amount of Securities of such series
of a denomination larger than the minimum authorized denomination for Securities of that series or of the principal amount of
global securities of such series. If less than 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 and specified tenor not previously called for redemption in accordance with the
preceding sentence. If so specified in the Securities of a series, partial redemptions must be in an amount not less than $1,000,000
principal amount of Securities.

 

    	-47-

    	 

    

 

The Trustee shall promptly
notify the Company in writing of the Securities selected for redemption as aforesaid and, in case of any Securities selected for
partial redemption as aforesaid, the principal amount thereof to be redeemed.

 

The provisions of the
two preceding paragraphs shall not apply with respect to any redemption affecting only a single Security, whether such Security
is to be redeemed in whole or in part. In the case of any such redemption in part, the unredeemed portion of the principal amount
of the Security shall be in an authorized denomination (which shall not be less than the minimum authorized denomination) for such
Security.

 

For all purposes of this
Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities shall relate, in the
case of any 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 11.04.         Notice
of Redemption. Notice of redemption shall be given in the manner provided in Section 1.06 to the Holders of Securities

the Company shall be deemed to have been discharged from its obligations with respect to the Outstanding Securities of any series

means that the Company shall be deemed to have paid and discharged the entire indebtedness represented by the Outstanding Securities
of such series and to have satisfied all its other obligations under the Securities of such series and this Indenture insofar
as the Securities of such series are concerned (and the Trustee, at the expense of the Company, shall execute proper instruments
acknowledging the same), except for the following which shall survive until otherwise terminated or discharged hereunder: (A)
the rights of Holders of the Securities of such series to receive, solely from the trust fund described in Section 13.04

for the benefit of the Holders of such Securities and (ii) the occurrence of an event specified in Sections 5.01(4),
(5), (6) or (7) shall not be deemed to be an Event of Default on and after the date the conditions set forth

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 Clause whether directly or indirectly by reason of any reference elsewhere herein to any such Section or Clause or
by reason of any reference in any such Section or Clause to any other provision herein or in any other document, but the remainder
of this Indenture and such Securities shall be unaffected thereby.

 

Section 13.04.         Conditions
to Defeasance or Covenant Defeasance. The following shall be the conditions to application of either Section 13.02
or Section 13.03 to the then Outstanding Securities of any series:

 

    	-51-

    	 

    

 

(1)         The
Company shall irrevocably have deposited or caused to be deposited with the Trustee (or another trustee satisfying the requirements
of Section 6.09 who shall agree to comply with the provisions of this Article XIII applicable to it) as trust funds
in trust for the purpose of making the following payments specifically pledged as security for, and dedicated solely to, the benefit
of the Holders of the Securities of such series, (A) money in an amount, or (B) Government Obligations which through the scheduled
payment of principal and interest in respect thereof in accordance with their terms will provide, not later than one day before
the due date of any payment, money in an amount, or (C) a combination thereof, sufficient, in the opinion of a nationally recognized
firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, to pay and discharge,
and which shall be applied by the Trustee (or other qualifying trustee) to pay and discharge, the principal of, premium, if any,
and each installment of interest on the Securities on the Stated Maturity of such principal or installment of interest in accordance
with the terms of this Indenture and of the Securities of such series. For this purpose, “Government Obligations”
means, with respect to any series of Securities, securities that are (x) direct obligations of the government that issued the currency
in which such series is denominated (or, if such series is denominated in euro, the direct obligations of any government that is
a member of the European Monetary Union) for the payment of which its full faith and credit is pledged or (y) obligations of a
Person controlled or supervised by and acting as an agency or instrumentality of such government the payment of which is unconditionally
guaranteed as a full faith and credit obligation by such government, which, in either case, are not callable or redeemable at the
option of the issuer thereof and shall also include a depositary receipt issued by a bank (as defined in Section 3(a)(2) of the
Securities Act) as custodian with respect to any Government Obligation where the relevant government is the United States of America
or a specific payment of principal of or interest on any such Government Obligation held by such custodian for the account of the
holder of such depositary receipt, provided that (except as required by law) such custodian is not authorized to make any
deduction from the amount payable to the holder of such depository receipt from any amount received by the custodian in respect
of the such Government Obligation or the specific payment of principal of or interest on such Government Obligation evidenced by
such depository receipt.

 

(2)         In
the event of an election to have Section 13.02 apply to any Securities or any series of Securities, as the case may be,
the Company shall have delivered to the Trustee an opinion of Counsel stating that (x) the Company has received from, or there
has been published by, the Internal Revenue Service a ruling, or (y) since the date 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 the Outstanding Securities of such series will not recognize gain or loss for Federal income tax purposes as a result
of such deposit, defeasance and discharge and will be subject to Federal income tax on the same amount, in the same manner and
at the same times as would have been the case if such deposit, defeasance and discharge had not occurred.

 

(3)         In
the event of an election to have Section 13.03 apply to any Securities or any series of Securities, as the case may be,
the Company shall have delivered to the Trustee an Opinion of Counsel to the effect the that Holders of the Outstanding Securities
of such series will not recognize gain or loss for Federal income tax purposes as a result of such deposit and covenant defeasance
and will be subject to Federal income tax on the same amount, in the same manner and at the same times as would have been the case
if such deposit and covenant defeasance had not occurred.

 

    	-52-

    	 

    

 

(4)         No
Event of Default or event which with notice or lapse of time or both would become an Event of Default with respect to the Securities
of such series shall have occurred and be continuing on the date of such deposit or, insofar as Sections 5.01(5) and (6)
are concerned, at any time during the period ending on the 90th day after the date of such deposit (it being understood that this
condition shall not be deemed satisfied until the expiration of such period).

 

(5)         Such
defeasance or covenant defeasance shall not cause the Trustee to have a conflicting interest as defined in Section 6.08
and for purposes of the Trust Indenture Act with respect to any securities of the Company.

 

(6)         Such
defeasance or covenant defeasance shall not result in a breach or violation of, or constitute a default under, any other agreement
or instrument to which the Company is a party or by which it is bound.

 

(7)         The
Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions
precedent provided for relating to either the defeasance under Section 13.02 or the covenant defeasance under Section
13.03 (as the case may be) have been complied with.

 

(8)         Such
defeasance or covenant defeasance shall not result in the trust arising from such deposit constituting an investment company as
defined in the Investment Company Act, or such trust shall be qualified under such act or exempt from regulation thereunder.

 

Section 13.05.         Deposited
Money and Government Obligations to be Held in Trust; Other Miscellaneous Provisions. Subject to the provisions of the last
paragraph of Section 10.03, all money and Government Obligations (including the proceeds thereof) deposited with the
Trustee (or other qualifying trustee (solely for purposes of this Section and Section 13.06, the Trustee and any such
other trustee are referred to collectively, for purposes of this Section 13.05, as the “Trustee”)
pursuant to Section 13.04 in respect of the Securities of such series shall be held in trust and applied by the Trustee,
in accordance with the provisions of such Securities of such series 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 the Securities
of such series, of all sums due and to become due thereon in respect of principal (and premium, if any) and interest, but such
money need not be segregated from other funds except to the extent required by law.

 

The Company shall pay
and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the Government Obligations deposited
pursuant to Section 13.04 or the principal and interest received in respect thereof other than any such tax, fee or
other charge which by law is for the account of the Holders of the Outstanding Securities.

 

    	-53-

    	 

    

 

Anything in this Article
XIII to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon Company Request
any money or Government Obligations held by it as provided in Section 13.04 which, in the opinion of a nationally recognized
firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, are in excess of
the amount thereof which would then be required to be deposited to effect an equivalent defeasance or covenant defeasance.

 

Section 13.06.         Reinstatement.
If the Trustee or the Paying Agent is unable to apply any money in accordance with Section 13.02 or 13.03 by reason
of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application,
then the Company’s obligations under this Indenture and the Securities of such series shall be revived and reinstated as
though no deposit had occurred pursuant to this Article XIII until such time as the Trustee or Paying Agent is permitted
to apply all such money in accordance with Section 13.02 or 13.03; provided, however, that if the
Company makes any payment of principal of (and premium, if any) or interest on any Security following the reinstatement of its
obligations, the Company shall be subrogated to the rights of the Holders of the Securities of such series to receive such payment
from the money held by the Trustee or the Paying Agent.

 

Section 13.07.         Counterpart
Originals. This instrument may be executed in any number of counterparts, each of which so executed shall be deemed to be an
original, but all such counterparts shall together constitute but one and the same instrument.

 

The exchange of copies
of this Indenture and of signature pages by facsimile or PDF transmission shall constitute effective execution and delivery
of this Indenture as to the parties hereto and may be used in lieu of the original Indenture for all purposes. Signatures of the
parties hereto transmitted by facsimile or PDF shall be deemed to be their original signatures for all purposes.

Section 3.04         Exchange
and Registration of Transfer of Notes; Depositary.

 

(a)          Notwithstanding
the provisions of Section 3.05 of the Base Indenture, None of the Company, the Trustee or the Registrar shall be required to exchange
Notes for other Notes or register a transfer of (i) any Notes surrendered for conversion in accordance with Article 8 for Shares,
or, if a portion of any Note is surrendered for conversion for Shares, such portion thereof surrendered for conversion in accordance
with Article 8 or (ii) any Notes, or a portion of any Note, surrendered for repurchase (and not withdrawn) in accordance with Article
9.

 

(b)          So
long as the Notes are eligible for book-entry settlement with the Depositary, unless otherwise required by law, all Notes shall
be represented by one or more Global Notes (each, a “Global Note”) registered in the name of the Depositary or the
nominee of the Depositary. The transfer and exchange of beneficial interest in a Global Note that does not involve the issuance
of a Physical Note, shall be effected through the Depositary (but not the Trustee or the Custodian) in accordance with the Indenture
(including the restrictions on transfer set forth herein) and the Applicable Procedures.

 

(c)          The
Depositary shall be a clearing agency registered under the Exchange Act. The Company initially appoints The Depository Trust Company
to act as Depositary with respect to each Global Note. Initially, each Global Note shall be issued to the Depositary, registered
in the name of Cede & Co., as the nominee of the Depositary, and deposited with the Trustee as custodian for Cede & Co.
A Global Note may be transferred, in whole or in part, only to another nominee of DTC or to a successor of DTC or its nominee.

 

(d)          The
Company shall cause to be kept an office or agency where Notes may be presented for conversion in accordance with Article 8 of
this First Supplemental Indenture (the “Conversion Agent”). The Company initially appoints the Trustee as Conversion
Agent. The Company may have one or more additional Conversion Agents with respect to the Notes. If the Company fails to maintain
an Conversion Agent, the Trustee shall act as such. The Company or any Affiliate of the Company may act as Conversion Agent; provided
that neither the Company nor an Affiliate of the Company shall act as Conversion Agent in connection with the discharge of the
Indenture under Article 4 of the First Supplemental Indenture.

 

(e)          For
the avoidance of doubt, the penultimate paragraph of Section 3.05 of the Base Indenture shall not apply to the Notes.

 

Section 3.05         Mutilated,
Destroyed, Lost or Stolen Notes. Solely for purposes of the Notes, the third and
fourth paragraphs of Section 3.06 of the Base Indenture are hereby deleted in their entirety and replaced with the following:
“In case any Note that has matured or is about to mature or has been surrendered for required repurchase or is about to
be converted in accordance with Article 8 shall become mutilated or be destroyed, lost or stolen, the Company may, in its sole
discretion, instead of issuing a substitute Note, pay or authorize the payment of or convert or authorize the conversion of the
same (without surrender thereof except in the case of a mutilated Note), as the case may be, if the applicant for such payment
or conversion shall furnish to the Company, to the Trustee and, if applicable, to such authenticating agent such security or indemnity
as may be required by them to save each of them harmless for any loss, liability, cost or expense caused by or connected with
such substitution, and, in every case of destruction, loss or theft, evidence satisfactory to the Company, the Trustee and, if
applicable, any Paying Agent or Conversion Agent evidence of their satisfaction of the destruction, loss or theft of such Note
and of the ownership thereof. No service charge shall be imposed by the Company, the Trustee, the Registrar, any co-Registrar
or the Paying Agent upon the issuance of any substitute Note, but the Company may require a Holder to pay a sum sufficient to
cover any documentary, stamp or similar issue or transfer tax required in connection therewith as a result of the name of the
Holder of the new substitute Note being different from the name of the Holder of the old Note that became mutilated or was destroyed,
lost or stolen.”

Section 3.06         Additional
Notes; Repurchases. The Company may, without the consent of the Holders and notwithstanding
Section 3.01, reopen the Indenture and issue additional Notes hereunder with the same terms and with the same CUSIP number as
the Notes initially issued hereunder in an unlimited aggregate principal amount; provided that if any such additional Notes
are not fungible with the Notes initially issued hereunder for U.S. federal income tax purposes, such additional Notes shall have
a separate CUSIP number. Prior to the issuance of any such additional Notes, the Company shall deliver to the Trustee a Company
Order, an Officers’ Certificate and an Opinion of Counsel, such Officers’ Certificate and Opinion of Counsel to cover
such matters as the Trustee shall reasonably request. In addition, the Company may, to the extent permitted by law, and directly
or indirectly (regardless of whether such Notes are surrendered to the Company), repurchase Notes in the open market or otherwise,
whether by the Company or its Subsidiaries or through a private or public tender or conversion offer or through counterparties
to private agreements, including by cash-settled swaps or other derivatives. The Company shall cause any Notes so repurchased
(other than Notes repurchased pursuant to cash-settled swaps or other derivatives) to be surrendered to the Trustee for cancellation
in accordance with Section 3.09 of the Base Indenture.

theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged

sums due and payable under the Indenture by the Company; and (b) the Company has delivered to the Trustee an Officers’ Certificate
and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge
of the Indenture have been complied with. Notwithstanding the satisfaction and discharge of this First Supplemental Indenture,

Interest. Notwithstanding anything in the Indenture or in the Notes to the contrary,

Notes outstanding during the 180-day period beginning on the 186th day following the Event of Default. In the event the Company
does not elect to pay the Additional Interest upon an Event of Default in accordance with this paragraph, the Notes will be subject
to acceleration as provided above. The Additional Interest will accrue on all outstanding Notes from and including the date on
which an Event of Default relating to a failure to comply with the obligations in Section 5.03(b) first occurs to, and including,
the 365th day thereafter (or such earlier date on which the Event of Default relating to the reporting obligations shall have
been cured or waived). On the 366th day, if such Event of Default is continuing, such Additional Interest will cease to accrue

not affect the rights of Holders of Notes in the event of the occurrence of any other Event of Default. In no event shall Additional
Interest accrue at a rate in excess of the applicable rate specified above, regardless of the number of events or circumstances
giving rise to requirements to pay such Additional Interest pursuant to this paragraph. In the event the Company does not elect
to pay Additional Interest following an Event of Default in accordance with this Section 6.02 or the Company elected to make such
payment but does not pay the Additional Interest when due, the Notes shall be subject to acceleration as provided in Section 6.01(b).

as the sole remedy during the first 365 days after the occurrence of any Event of Default described in the immediately preceding
paragraph, the Company must notify all Holders of the Notes, the Trustee and the Paying Agent of such election prior to the beginning
of such 365-day period. Upon the failure to timely give such notice, the Notes shall be immediately subject to acceleration as
provided in Section 6.01(b).

 

Section 6.03         Waiver
of Past Defaults. The Holders of a majority in aggregate principal amount of the
Notes outstanding, may, by written notice to the Company and the Trustee, after a declaration of acceleration, but before a judgment
of decree for payment of the money due has been obtained by the Trustee, rescind and annual such declaration if:

 

(a)          The
Company has paid (or deposited with the Trustee a sum sufficient to pay) (i) all overdue interest on all Notes; (ii) the principal
amount of any Notes that have become due otherwise than by such declaration or acceleration; (iii) to the extent that payment of
such interest is lawful, interest upon overdue interest; and (iv) all sums paid or advanced by the Trustee under the Indenture
and reasonable compensation expenses, disbursements and advances of the Trustee, its agents and counsel, and

 

(b)          All
Events of Default, other than the non-payment of the principal amounts and any accrued and unpaid interest that have become due
solely by such declaration of acceleration, have been cured or waived.

 

Section 6.04         Notice
of Defaults.

 

(a)          Within
90 calendar days of becoming aware of the occurrence of any default, the Trustee shall give notice to Holders of the Notes notice
of all uncured defaults known to it. The Trustee may withhold notice to the Holder of the Notes of any default, except defaults
in payment of principal or interest on the Notes of defaults in the failure to deliver the consideration due upon conversion, if
the Trustee, in good faith, determines that the withholding of such notice in in the interet of the Holders.

(ii) in the case of a Physical Note (1) complete, manually sign and deliver an irrevocable notice to the Conversion Agent as set
forth in the Form of Notice of Conversion (or a facsimile thereof) (a “Notice of Conversion”) at the office
of the Conversion Agent and state in writing therein the principal amount of Notes to be converted and the name or names (with
addresses) in which such Holder wishes the certificate or certificates for any Shares to be delivered upon settlement of the Conversion
Obligation to be registered, (2) surrender such Notes, duly endorsed to the Company or in blank (and accompanied by appropriate
endorsement and transfer documents), at the office of the Conversion Agent, (3) if required, furnish appropriate endorsements and
transfer documents and (4) if required, pay funds equal to interest payable on the next Interest Payment Date to which such Holder
is not entitled as set forth in Section 8.02(h). The Trustee (and if different, the Conversion Agent) shall notify the Company
of any conversion pursuant to this Article 8 on the Conversion Date for such conversion. No Notice of Conversion with respect to
any Notes may be surrendered by a Holder thereof if such Holder has also delivered a Fundamental Change Repurchase Notice to the
Company in respect of such Notes and not validly withdrawn such Fundamental Change Repurchase Notice in accordance with Section
9.02.

 

If more than one Note shall be surrendered
for conversion at one time by the same Holder, the Conversion Obligation with respect to such Notes shall be computed on the basis
of the aggregate principal amount of the Notes (or specified portions thereof to the extent permitted thereby) so surrendered.

 

(d)          A
Note shall be deemed to have been converted immediately prior to the close of business on the date that the Holder has complied
with the requirements set forth in subsection (b) above (the “Conversion Date”). The Company shall cause to
be issued and deliver to the Conversion Agent or to such Holder, or such Holder’s nominee or nominees, certificates or a
book-entry transfer through the Depositary for the full number of Shares to which such Holder shall be entitled in satisfaction
of the Company’s Conversion Obligation.

 

(e)          In
case any Note shall be surrendered for partial conversion, the Company shall execute and the Trustee shall authenticate and deliver
to or upon the written order of the Holder of the Note so surrendered a new Note or Notes in authorized denominations in an aggregate
principal amount equal to the unconverted portion of the surrendered Note, without payment of any service charge by the exchanging
Holder but, if required by the Company or Trustee, with payment of a sum sufficient to cover any transfer tax or similar governmental
charge required by law or that may be imposed in connection therewith as a result of the name of the Holder of the new Notes issued
upon such conversion being different from the name of the Holder of the old Notes surrendered for such conversion.

 

    	18

    	 

    

 

(f)          The
Company shall pay any transfer or similar taxes due upon conversion other than any tax or duty that may be payable relating to
any transfer involved in the issuance or delivery of Shares, if any, due upon conversion in a name other than that of the converting
Holder, which such taxes shall be the obligation of the Holder. Certificates representing Shares shall be issued and delivered
only after all applicable transfer or similar taxes, if any, payable by the Holder have been paid in full.

 

(g)          Except
as provided in Section 8.04, no adjustment shall be made for dividends on any Shares delivered upon the conversion of any Note
as provided in this Article 8.

 

(h)          Upon
the conversion of an interest in a Global Note, the Trustee, or the Custodian at the direction of the Trustee, shall make a notation
on such Global Note as to the reduction in the principal amount represented thereby. The Company shall notify the Trustee in writing
of any conversion of Notes effected through any Conversion Agent other than the Trustee.

 

(i)          Upon
conversion, a Holder shall not receive any separate cash payment for accrued and unpaid interest, if any, except as set forth below.
The Company’s settlement of the Conversion Obligation shall be deemed to satisfy in full its obligation to pay the principal
amount of the Note and accrued and unpaid interest, if any, to, but not including, the relevant Conversion Date. As a result, accrued
and unpaid interest, if any, to, but not including, the relevant Conversion Date shall be deemed to be paid in full rather than
cancelled, extinguished or forfeited. Notwithstanding the foregoing, if Notes are converted after the close of business on a Regular
Record Date, Holders of such Notes as of the close of business on such Regular Record Date will receive the full amount of interest
payable on such Notes on the corresponding Interest Payment Date notwithstanding the conversion. Notes surrendered for conversion
during the period from the close of business on any Regular Record Date to the open of business on the immediately following Interest
Payment Date must be accompanied by funds equal to the amount of interest payable on the Notes so converted; provided that
no such payment shall be required (1) for conversions following the Regular Record Date immediately preceding the Maturity Date;
(2) if the Company has specified a Fundamental Change Repurchase Date that is after a Regular Record Date and on or prior to the
Business Day immediately following the corresponding Interest Payment Date; or (3) to the extent of any Defaulted Interest, if
any Defaulted Interest exists at the time of conversion with respect to such Note.

 

(j)          The
Person in whose name the certificate for any Shares delivered upon conversion is registered shall be treated as a stockholder of
record as of the close of business on the Conversion Date. Upon a conversion of Notes, such Person shall no longer be a Holder
of such Notes surrendered for conversion.

 

(k)          Notwithstanding
the foregoing, the Company shall not deliver any fractional shares upon conversion and instead shall deliver cash in lieu of fractional
shares based on the Last Reported Sale Price of the Shares on the Conversion Date (or, if the Conversion Date is not a Trading
Day, the next following Trading Day).

 

    	19

    	 

    

 

Section 8.03         Increased
Conversion Rate Applicable to Certain Notes Surrendered in Connection with Make-Whole Fundamental Changes.
(a) If a Make-Whole Fundamental Change occurs prior to the Maturity Date and a Holder elects to convert its Notes in connection
with such Make-Whole Fundamental Change, the Company shall, under the circumstances described below, increase the Conversion Rate
for the Notes so surrendered for conversion by a number of additional Shares (the “Additional Shares”), as
described below. A conversion of Notes shall be deemed for these purposes to be “in connection with” such Make-Whole
Fundamental Change if the Conversion Date occurs on or following the Effective Date of the Make-Whole Fundamental Change but before
the close of business on the second Scheduled Trading Day immediately preceding the related Fundamental Change Repurchase Date.

 

(b)          Upon
surrender of Notes for conversion in connection with a Make-Whole Fundamental Change, the Company shall pay or deliver, as the
case may be, the consideration due in respect of such converted Notes in accordance with Section 8.02 based on the Conversion Rate
as increased to reflect the Additional Shares pursuant to the table below; provided, however, that if, at the effective
time of a Make-Whole Fundamental Change described in clause (b) of the definition of Fundamental Change, the Reference Property
following such Make-Whole Fundamental Change is composed entirely of cash, for any conversion of Notes following the Effective
Date of such Make-Whole Fundamental Change, the Conversion Obligation shall be calculated based solely on the Share Price for the
transaction and shall be deemed to be an amount of cash per $1,000 principal amount of converted Notes equal to the Conversion
Rate (including any adjustment for Additional Shares), multiplied by such Share Price. In such event, the Conversion Obligation
shall be paid to Holders in cash on the third Business Day following the Conversion Date. The Company shall notify the Holders
of Notes of the Effective Date of any Make-Whole Fundamental Change and issue a press release announcing such Effective Date no
later than five Business Days after such Effective Date.

 

(c)          The
number of Additional Shares, if any, by which the Conversion Rate shall be increased shall be determined by reference to the table
below, based on the date on which the Make-Whole Fundamental Change occurs or becomes effective (the “Effective Date”)
and the price (the “Share Price”) paid (or deemed to be paid) per share of the Shares in the Make-Whole Fundamental
Change. If the holders of the Shares receive in conversion for their Shares only cash in a Make-Whole Fundamental Change described
in clause (b) of the definition of Fundamental Change, the Share Price shall be the cash amount paid per Share. Otherwise, the
Share Price shall be the average of the Last Reported Sale Prices of the Shares over the five Trading Day period ending on, and
including, the Trading Day immediately preceding the Effective Date of the Make-Whole Fundamental Change. The Company’s Board
of Directors shall make appropriate adjustments to the Share Price, in its good faith determination, to account for any adjustment
to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the Ex-Dividend
Date of the event occurs, during such five consecutive Trading Day period.

 

(d)          The
Share Prices set forth in the column headings of the table below shall be adjusted as of any date on which the Conversion Rate
of the Notes is otherwise adjusted. The adjusted Share Prices shall equal the Share Prices applicable immediately prior to such
adjustment, multiplied by a fraction, the numerator of which is the Conversion Rate immediately prior to such adjustment
giving rise to the Share Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of Additional
Shares set forth in the table below shall be adjusted in the same manner and at the same time as the Conversion Rate as set forth
in Section 8.04.

 

    	20

    	 

    

 

(e)          The
following table sets forth the number of Additional Shares to be received per $1,000 principal amount of Notes pursuant to this
Section 8.03 for each Share Price and Effective Date set forth below:

The exact Share Prices and Effective Dates
may not be set forth in the table above, in which case:

 

(i)          if
the Share Price is between two Share Prices in the table above or the Effective Date is between two Effective Dates in the table,
the number of Additional Shares shall be determined by a straight-line interpolation between the number of Additional Shares set
forth for the higher and lower Share Prices and the earlier and later Effective Dates, as applicable, based on a 365-day year;

 

(ii)         if
the Share Price is greater than $125.00 per share (subject to adjustment in the same manner as the Share Prices set forth in the
column headings of the table above pursuant to subsection (d) above), no Additional Shares shall be added to the Conversion Rate;
and

 

(iii)        if
the Share Price is less than $66.50 per share (subject to adjustment in the same manner as the Share Prices set forth in the column
headings of the table above pursuant to subsection (d) above), no Additional Shares shall be added to the Conversion Rate.

 

Notwithstanding the foregoing, in no event shall the Conversion
Rate per $1,000 principal amount of Notes exceed 15.0375, subject to adjustment in the same manner as the Conversion Rate pursuant
to Section 8.04.

 

(f)          Nothing
in this Section 8.03 shall prevent an adjustment to the Conversion Rate pursuant to Section 8.04 in respect of a Make-Whole Fundamental
Change.

 

Section 8.04         Adjustment
of Conversion Rate. The Conversion Rate shall be adjusted from time to time by
the Company if any of the following events occurs, except that the Company shall not make any adjustments to the Conversion Rate
if Holders of the Notes participate (other than in the case of a share split or share combination), at the same time and upon
the same terms as holders of the Shares and solely as a result of holding the Notes, in any of the transactions described in this
Section 8.04, without having to convert their Notes, as if they held a number of Shares equal to the Conversion Rate, multiplied
by the principal amount (expressed in thousands) of Notes held by such Holder.

 

    	21

    	 

    

 

(a)          If
the Company issues Shares as a dividend or distribution on Shares, or if the Company effects a share split or share combination,
the Conversion Rate will be adjusted based on the following formula:

 

	 	CR 1 = CR 0  ×	 OS 1

_______

OS 0	 

 

where,

 

	CR 1 =	the Conversion Rate in effect immediately prior to the open of business on the Record Date for such dividend or distribution or the effective date of such share split or combination, as the case may be;

 

	CR 0 =	the Conversion Rate in effect at 5:00 p.m., New York City time, on the Trading Day immediately preceding the Record Date for such dividend or distribution or the effective date of such share split or combination, as the case may be;

 

	OS 0 =	the number of Shares outstanding at 5:00 p.m., New York City time, on the Trading Day immediately preceding the Record Date for such dividend or distribution or the effective date of such share split or combination;

 

	OS 1 =	the number of Shares that would be outstanding immediately after, and solely as a result of, such dividend, distribution, share split or combination, as the case may be.

 

Any adjustment made under this Section 8.04(a) shall become
effective immediately after the open of business on the Record Date for such dividend or distribution, or immediately after the
open of business on the effective date for such share split or share combination, as applicable. If any dividend or distribution
of the type described in this Section 8.04(a) is declared but not so paid or made, the Conversion Rate shall be immediately readjusted,
effective as of the date that the Company’s Board of Directors determines not to pay such dividend or distribution, to the
Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

 

(b)          If
the Company distributes to all or substantially all holders of its Shares any rights, options or warrants entitling them to purchase,
for a period of 45 calendar days or less from the declaration date for such distribution, Shares at a price per share less than
the average closing sale price of the Shares for the ten consecutive Trading Days immediately preceding, but excluding, the declaration
date for such distribution, the Conversion Rate will be increased based on the following formula:

 

	 	CR 1 = CR0  ×	OS 0 + X

__________

OS 0 + Y	 

 

    	22

    	 

    

 

where,

 

	CR 1 =	Conversion Rate in effect immediately prior to the open of business on the Record Date for such distribution;

 

	CR 0 =	the Conversion Rate in effect at 5:00 p.m., New York City time, on the Trading Day immediately preceding the Record Date for such distribution;

 

	OS 0 =	the number of Shares outstanding at 5:00 p.m., New York City time, on the Trading Day immediately preceding the Record Date for such distribution;

 

	X =	the total number of Shares issuable pursuant to such rights or warrants; and

 

	Y =	the number of Shares equal to the aggregate price payable to exercise such rights or warrants, divided by the average of the closing prices of the Shares over the 10 consecutive Trading Day period ending on the Trading Day immediately preceding the Record Date for such distribution.

 

Any increase made under this Section 8.04(b) will be made successively
whenever any such rights, options or warrants are distributed and shall become effective immediately after the open of business
on the Ex-dividend Date for such distribution. To the extent that Shares are not delivered after the expiration of such rights,
options or warrants, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect had the increase
with respect to the distribution of such rights, options or warrants been made on the basis of delivery of only the number of Shares
actually delivered. If such rights, options or warrants are not so distributed, the Conversion Rate shall be decreased to the Conversion
Rate that would then be in effect if such Ex-dividend Date for such distribution had not occurred.

 

For the purpose of this Section 8.04(b), in
determining whether any rights, options or warrants entitle the Holders to purchase Shares at a price per share less than such
average closing sale price for the 10 consecutive Trading Days immediately preceding, but excluding, the declaration date for such
distribution, and in determining the aggregate offering price of such Shares, there shall be taken into account any consideration
received by the Company for such rights, options or warrants and any amount payable upon exercise or conversion thereof, the value
of such consideration, if other than cash, to be determined by the Company’s Board of Directors.

 

(c)          (i)
If the Company distributes Shares, evidences of its indebtedness or other of the Company’s securities, assets or property
to all or substantially all holders of its Shares, excluding (1) dividends, distributions or issuances as to which an adjustment
was effected pursuant to Section 8.04(a) or Section 8.04(b), (2) the initial distribution of rights issued pursuant to a shareholders
rights plan; provided that such rights plan provides for the issuance of such rights with respect to the Shares issued upon conversion
of the Notes; (3) dividends or distributions paid exclusively in cash, and (4) Spin-Offs as to which the provisions set forth below
in Section 8.04(c)(ii) shall apply (any of such shares evidences of indebtedness, other assets or property, the “Distributed
Property”), then the Conversion Rate shall be increased based on the following formula:

 

    	23

    	 

    

 

	 	CR 1 = CR 0  ×	SP 0

___________

SP 0 – FMV	 

 

where,

 

	CR 1 =	Conversion Rate in effect immediately prior to the open of business on the Record Date for such distribution;

 

	CR 0 =	the Conversion Rate in effect at 5:00 p.m., New York City time, on the Trading Day immediately preceding the Record Date for such distribution;

 

	SP 0 =	the average of the closing prices of the Shares over the 10 consecutive Trading Day period ending on the Trading Day immediately preceding the Record Date for such distribution; and

 

	FMV =	the fair market value (as determined by the Company’s Board of Directors) of the shares of capital stock, evidences of indebtedness, assets or property distributed with respect to each outstanding share as of the open of business on the Record Date for such distribution.

 

Any increase made under this Section 8.04(c)(i) will become
effective immediately after the open of business on the Ex-dividend Date for such distribution. If such distribution is not so
paid or made, the Conversion Rate shall be decreased to be the Conversion Rate that would then be in effect if such distribution
had not been declared.

 

Notwithstanding the foregoing, if “FMV” (as defined
above) is equal to or greater than “SP 0 ” (as defined above), or if the difference between “SP 0
” and “FMV” is less than $1.00, in lieu of the foregoing increase, each Holder of a Note shall receive, in respect
of each $1,000 principal amount thereof, at the same time and upon the same terms as holders of the Company’s Shares without
having to convert its Notes, the amount and kind of the Company’s capital stock, evidences of the Company’s indebtedness
or other of its securities, assets or property that such Holder would have received as if such Holder owned a number of Shares
equal to the Conversion Rate in effect on the Ex-dividend Date for the distribution.

 

(ii) With respect to an adjustment pursuant
to this Section 8.04(c) where there has been a payment of a dividend or other distribution on the shares of LLC interests of any
class or series, or similar equity interest, of or relating to a Subsidiary or other business unit of the Company, that will be,
upon distribution, listed or admitted for trading on a U.S. national or regional securities exchange (a “Spin-Off”),
the Conversion Rate shall be increased based on the following formula:

 

	 	CR 1 = CR 0  ×	
        FMV
        + MP 0

        __________

        MP 0
	 

 

    	24

    	 

    

 

where,

 

	CR 1 =	Conversion Rate in effect immediately prior to the open of business on the Record Date for the spin-off;

 

	CR 0 =	the Conversion Rate in effect at 5:00 p.m., New York City time, on the Trading Day immediately preceding the Record Date for the spin-off;

 

	FMV =	the average of the closing prices of the LLC interests or similar equity interest distributed to holders of Shares applicable to one share over the first 10 consecutive Trading Day period immediately following, and including, the third Trading Day after the Record Date for such spin-off (such period, the “Valuation Period”); and

 

	MP 0 =	the average of the closing prices of Shares over the Valuation Period.

 

Any adjustment to the Conversion Rate under this Section 8.04(c)(ii)
will be made immediately after the open of business on the day after the last day of the Valuation Period, but shall be given effect
as of the open of business on the Record Date for the Spin-Off. Because the Company makes the adjustment to the Conversion Rate
at the end of the Valuation Period with retroactive effect, the Company shall delay the settlement of any Notes where the final
day of the related observation period occurs during the Valuation Period. In such event, the Company shall pay the principal portion
and deliver Shares, if any, and any cash in lieu thereof (based on the adjusted Conversion Rate as described above) on the third
business day immediately following the last day of the Valuation Period.

 

(d)          If
any cash dividend or distribution in cash is made to all or substantially all holders of the Shares, the Conversion Rate shall
be adjusted based on the following formula:

 

	 	
        CR 1  = CR
0  ×
	SP 0  - DTA

____________

SP 0  - C	 

 

where,

 

	CR 1 =	Conversion Rate in effect immediately prior to the open of business on the Record Date for such dividend or distribution;

 

	CR 0 =	the Conversion Rate in effect at 5:00 p.m., New York City time, on the Trading Day immediately preceding the Record Date for such distribution;

 

	SP 0 =	the Last Reported Sale Prices of the Shares over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-dividend date for such distribution;

 

	DTA =	the dividend threshold amount, which shall equal $0.95 per share in any quarter; and

 

	C =	the amount in cash per share distributed to holders of Shares.

 

The dividend threshold amount is subject to adjustment on an
inversely proportional basis whenever the Conversion Rate is adjusted. If an adjustment is required to be made as set forth in
this Section 8.04(d) as a result of a distribution that is not a regular quarterly dividend, the dividend threshold amount will
be deemed to be zero.

 

    	25

    	 

    

 

(e)          If
the Company or any of its Subsidiaries makes a payment in respect of a tender offer or exchange offer for Shares, to the extent
that the cash and value of any other consideration included in the payment per Share exceeds the closing price of the Shares on
the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer,
the Conversion Rate will be increased based on the following formula:

 

	 	
        CR 1  = CR
0  × 
 	
        AC + (SP 1  × OS
        1 )

        _________________

        OS 0  × SP 1
	 

 

where,

 

	CR 1 =	the Conversion Rate in effect at 5:00 p.m. on the day such tender offer or exchange offer expires;

 

	CR 0 =	the Conversion Rate in effect immediately prior to the open of business on the Trading Day next succeeding the date such tender offer or exchange offer expires;

 

	AC =	the aggregate value of all cash and any other consideration (as determined by The Company’s Board of Directors) paid or payable for Shares purchased in such tender or exchange offer;

 

	SP 1 =	the average of the closing prices of Shares over the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the date such tender or exchange offer expires (the “Averaging Period”);

 

	OS 1 =	the number of Shares outstanding immediately after the close of business on the date such tender or exchange offer expires (after giving effect to such tender offer or exchange offer); and

 

	OS 0 =	the number of Shares outstanding immediately prior to the date such tender or exchange offer expires (prior to giving effect to such tender offer or exchange offer).

 

Any adjustment to the Conversion Rate under this Section 8.04(e)
will be made immediately prior to the open of business on the day following the last day of the Averaging Period, but will be given
effect as of the open of business on the Trading Day next succeeding the date such tender offer or exchange offer expires. Because
the Company shall make the adjustment to the Conversion Rate at the end of the Averaging Period with retroactive effect, the Company
shall delay the settlement of any Notes where the final day of the related observation period occurs during the Averaging Period.
In such event, the Company shall pay the principal portion and deliver Shares, if any, and any cash in lieu thereof (based on the
adjusted Conversion Rate as described above) on the third business day immediately following the last day of the Averaging Period.

 

    	26

    	 

    

 

(f)          The
Company shall not make any adjustments to the Conversion Rate to any Holder that participates (other than in the case of a share
split or share combination), without having to convert such Holder’s Notes, at the same time and upon the same terms as holders
of our Shares and as a result of holding the Notes, in any of the transactions described in Sections 8.03 or 8.04 if such Holder
held a number of Shares equal to the applicable Conversion Rate, multiplied by the principal amount (expressed in thousands)
of Notes held by such Holder.

 

(g)          Except
as stated herein, the Company shall not adjust the Conversion Rate for the issuance of Shares or any securities convertible into
or exchangeable for Shares or carrying the right to purchase Shares or such convertible or exchangeable securities.

 

(h)          In
addition to those adjustments required by clauses (a), (b), (c), (d) and (e) of this Section 8.04, and to the extent permitted
by applicable law and subject to the applicable rules of The New York Stock Exchange, the Company from time to time may increase
the Conversion Rate by any amount for a period of at least 20 Business Days if the Company’s Board of Directors determines
that such increase would be in the Company’s best interest. In addition, to the extent permitted by applicable law and subject
to the applicable rules of The New York Stock Exchange, the Company may (but is not required to) increase the Conversion Rate to
avoid or diminish any income tax to holders of Shares or rights to purchase Shares in connection with a dividend or distribution
of shares (or rights to acquire shares) or similar event. Whenever the Conversion Rate is increased pursuant to either of the preceding
two sentences, the Company shall mail to the Holder of each Note at its last address appearing on the Security Register a notice
of the increase at least 15 days prior to the date the increased Conversion Rate takes effect, and such notice shall state the
increased Conversion Rate and the period during which it will be in effect.

 

(i)          Notwithstanding
anything to the contrary in this Article 9, the Conversion Rate shall not be adjusted:

 

(i)          On
account of any stock repurchases that are not tender offers referred to in Section 9.04(e), including structured or derivative
transactions or transactions pursuant to a share repurchase program approved by the Company’s Board of Directors or otherwise.

 

(ii)         upon
the issuance of any Shares pursuant to any present or future plan providing for the reinvestment of dividends or interest payable
on the securities of the Company and the investment of additional optional amounts in Shares under any plan;

 

(iii)        upon
the issuance of any Shares or options or rights to purchase those shares pursuant to any present or future employee, director or
consultant benefit plan or program of or assumed by the Company or any of its Subsidiaries;

 

(iv)        upon
the issuance of any Shares pursuant to any option, warrant, right or exercisable, exchangeable or convertible security not described
in clause (iii) of this subsection and outstanding as of the date the Notes were first issued;

 

(v)         solely
for a change in the par value of the Shares;

 

    	27

    	 

    

 

(vi)        for
accrued and unpaid interest, if any; or

 

(vii)       for
an event otherwise requiring an adjustment as set forth in this Section 8.04, if such event is not consummated.

 

(viii)      All
calculations and other determinations under this Article 10 shall be made by the Company (or by the Board of Directors of the Company,
if so specified) and shall be made to the nearest one-ten thousandth (1/10,000) of a share.

 

(j)          Whenever
the Conversion Rate is adjusted as herein provided, the Company shall promptly file with the Trustee (and the Conversion Agent
if not the Trustee) an Officers’ Certificate setting forth the Conversion Rate after such adjustment and setting forth a
brief statement of the facts requiring such adjustment. Unless and until a Responsible Officer of the Trustee shall have received
such Officers’ Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion Rate and
may assume without inquiry that the last Conversion Rate of which it has knowledge is still in effect.

 

(k)          For
purposes of this Section 8.04, the number of Shares at any time outstanding shall not include shares held in the treasury of the
Company so long as the Company does not pay any dividend or make any distribution on Shares held in its treasury, but shall include
shares issuable in respect of scrip certificates issued in lieu of fractions of Shares. In addition, in the event of any adjustments
to the Conversion Rate as set forth in this Section 8.04, the Company shall issue a press release through Business Wire containing
the relevant information and make such information available on its website or through another public medium as it may use at that
time.

 

(l)          Notwithstanding
the foregoing, the Company not be required to make an adjustment in the Conversion Rate unless the adjustment would require a change
of at least 1% in the Conversion Rate. The Company shall carry forward any adjustment that is less than 1% of the Conversion Rate,
take such carried-forward adjustments into account in any subsequent adjustment, and make such carried forward adjustments, regardless
of whether the aggregate adjustment is less than 1%, (a) annually on the anniversary of the first date of issue of the Notes and
otherwise (b) at least 10 Business Days prior to the Maturity Date or any repurchase date, unless such adjustment has already been
made.

 

(m)          If
a taxable distribution to holders of our Shares or other transactions occur that result in any adjustment of the Conversion Rate
(including an adjustment at our option) you may, in certain circumstances, be deemed to have received a distribution subject to
US income tax as a dividend. In certain other circumstances, the absence of an adjustment may result in a taxable dividend to the
holder of our Shares.

 

Section 8.05         Adjustments
of Prices. Whenever any provision of the Indenture requires the Company to calculate
the closing sales prices or Last Reported Sale Prices over, or based on, a span of multiple days (including a conversion period,
or valuation period or averaging period), the Company shall make appropriate adjustments to each to account for any adjustment
to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the Ex-Dividend
Date of the event occurs, at any time during the period when the closing sale prices or Last Reported Sale Prices are to be calculated.

 

    	28

    	 

    

 

Section 8.06         Reservation
of Shares. The Company shall provide, free from preemptive rights, out of the Company’s
authorized but unissued shares or shares held in treasury, a number of Shares equal to the Conversion Rate multiplied by
the aggregate principal amount of Notes presented for conversion (expressed in thousands and assuming that at the time of computation
of such number of shares, all such Notes would be converted by a single Holder).

 

Section 8.07         Effect
of Recapitalizations, Reclassifications and Changes of the Shares.

 

(a)          In
the case of:

 

(i)          any
recapitalization, reclassification or change of the Shares (other than changes resulting from a subdivision or combination),

 

(ii)         any
consolidation, merger or combination involving the Company,

 

(iii)        any
sale, lease or other transfer to a third party of the consolidated assets of the Company and its Subsidiaries substantially as
an entirety or

 

(iv)        any
statutory share conversion,

 

in each case, as a result of which the Shares would be converted
into, or exchanged for, stock, other securities, other property or assets (including cash or any combination thereof) (any such
event, a “Merger Event”), then, at and after the effective time of such Merger Event, the Company shall exe
cute with the Trustee a supplemental indenture permitted under Section 7.02(c) providing that the right to convert each $1,000
principal amount of Notes shall be changed into a right to convert such principal amount of Notes for the kind and amount of shares
of stock, other securities or other property or assets (including cash or any combination thereof) that a Holder of a number of
Shares equal to the Conversion Rate immediately prior to such Merger Event would have owned or been entitled to receive (the “Reference
Property”, with each “unit of Reference Property” meaning the kind and amount of Reference Property
that a Holder of one Share is entitled to receive) upon such Merger Event provided, however, that at and after the
effective time of the Merger Event the Conversion Obligation shall be calculated and settlement in accordance with Section 8.02
shall apply such that (A) the number of Shares, if any, otherwise deliverable upon conversion of the Notes in accordance with Section
8.02 shall instead be deliverable in the amount and type of Reference Property that a Holder of that number of Shares would have
received in such Merger Event and (B) the last reported sale price shall be calculated based on the value of a unit of Reference
Property.

 

If the Merger Event causes the Shares to
be converted into, or exchanged for, the right to receive more than a single type of consideration (determined based in part upon
any form of stockholder election), then (i) the Reference Property for which the Notes will be convertible shall be deemed to be
the weighted average of the types and amounts of consideration received by the holders of Shares that affirmatively make such an
election, and (ii) the unit of Reference Property for purposes of the immediately preceding paragraph shall refer to the consideration
referred to in clause (i) attributable to one share of Shares.

 

    	29

    	 

    

 

If the holders of Shares receive only cash
in such Merger Event, then for all conversions that occur after the effective date of such Merger Event (x) the consideration due
upon conversion of each $1,000 principal amount of Notes shall be solely cash in an amount equal to the Conversion Rate in effect
on the Conversion Date (as may be increased by any Additional Shares pursuant to Section 8.03), multiplied by the price
paid per share of Shares in such Merger Event and (y) the Company shall satisfy the Conversion Obligation by paying cash to converting
Holders on the third Business Day immediately following the Conversion Date. The Company shall notify Holders, the Trustee and
the Conversion Agent (if other than the Trustee) of such weighted average as soon as practicable after such determination is made.

 

Such supplemental indenture described in
the second immediately preceding paragraph shall provide for anti-dilution and other adjustments that shall be as nearly equivalent
as is possible to the adjustments provided for in this Article 8. If, in the case of any Merger Event, the Reference Property includes
shares of stock, securities or other property or assets (including cash or any combination thereof) of a Person other than the
successor or purchasing corporation, as the case may be, in such Merger Event, then such supplemental indenture shall also be executed
by such other Person and shall contain such additional provisions to protect the interests of the Holders of the Notes as the Company’s
Board of Directors shall reasonably consider necessary by reason of the foregoing.

 

(b)          In
the event the Company shall execute a supplemental indenture pursuant to subsection (a) of this Section 8.07, the Company shall
promptly deliver to the Trustee an Officers’ Certificate briefly stating the reasons therefor, the kind or amount of cash,
securities or property or asset that will comprise a unit of Reference Property after any such Merger Event, any adjustment to
be made with respect thereto and that all conditions precedent have been complied with, and shall promptly mail notice thereof
to all Holders.

 

(c)          The
Company shall not become a party to any Merger Event unless its terms are consistent with this Section 8.07. None of the foregoing
provisions shall affect the right of a Holder of Notes to convert its Notes into Shares, if any, as set forth in Section 8.01 and
Section 8.02 prior to the effective date of such Merger Event.

 

(d)          The
above provisions of this Section shall similarly apply to successive Merger Events.

 

Section 8.08         Certain
Covenants. (a) The Company covenants that all Shares delivered upon conversion
of Notes will be fully paid and non-assessable and free from all taxes, liens and charges with respect to the issue and delivery
thereof.

 

(b)          The
Company further covenants that if at any time the Shares shall be listed on any national or regional securities exchange or automated
quotation system the Company will cause the Company to list and keep listed, so long as the Shares shall be so listed on such exchange
or automated quotation system, any Shares deliverable upon conversion of the Notes.

 

    	30

    	 

    

 

Section 8.09         Responsibility
of Trustee. The Trustee and any other Conversion Agent shall not at any time be
under any duty or responsibility to any Holder to determine the Conversion Rate (or any adjustment thereto) or whether any facts
exist that may require any adjustment (including any increase) of the Conversion Rate, or with respect to the nature or extent
or calculation of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture
provided to be employed, in making the same. The Trustee and any other Conversion Agent shall not be accountable with respect
to the validity or value (or the kind or amount) of any Shares, or of any securities, property or cash that may at any time be
issued or delivered upon the conversion of any Note; and the Trustee and any other Conversion Agent make no representations with
respect thereto. Neither the Trustee nor any Conversion Agent shall be responsible for any failure of the Company to issue or
of the Company to transfer or deliver any Shares or stock certificates or other securities or property or cash upon the surrender
of any Note for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained
in this Article. Without limiting the generality of the foregoing, neither the Trustee nor any Conversion Agent shall be under
any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant
to Section 8.07 relating either to the kind or amount of shares of stock or securities or property (including cash) receivable
by Holders upon the conversion of their Notes after any event referred to in such Section 8.07 or to any adjustment to be made
with respect thereto, but, subject to the provisions of Section 6.03 of the Base Indenture, may accept (without any independent
investigation) as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, the Officers’
Certificate (which the Company shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture)
with respect thereto.

 

Section 8.10         Shareholder
Rights Plans. To the extent that the Company has a rights plan in effect upon conversion
of the Notes, each share of Shares, if any, issued upon such conversion shall be entitled to receive the appropriate number of
rights, if any, and the certificates representing the Shares issued upon such conversion shall bear such legends, if any, in each
case as may be provided by the terms of any such shareholder rights plan, as the same may be amended from time to time. However,
if, prior to any conversion, the rights have separated from the Shares in accordance with the provisions of the applicable shareholder
rights plan so that the Holders would not be entitled to receive any rights in respect of Shares, if any, issuable upon conversion
of the Notes, the Conversion Rate shall be adjusted at the time of separation as if the Company distributed to all or substantially
all holders of the Shares Distributed Property as provided in Section 8.04(c), subject to readjustment in the event of the expiration,
termination or redemption of such rights.

Repurchase of Notes at Option of Holders

 

Section 9.01         Repurchase
at Option of Holders Upon a Fundamental Change. (a) If a Fundamental Change occurs
at any time prior to the Maturity Date, each Holder of Notes shall have the right, at such Holder’s option, to require the
Company to repurchase for cash all of such Holder’s Notes, or any portion thereof that is equal to $2,000 or an integral
multiple of $1,000 in excess thereof, on the date (the “Fundamental Change Repurchase Date”) specified by the
Company that is not less than 20 Business Days nor more than 35 Business Days following the date of the Fundamental Change Company
Notice at a repurchase price equal to 100% of the principal amount thereof, plus accrued and unpaid interest thereon to,
but excluding, the Fundamental Change Repurchase Date (the “Fundamental Change Repurchase Price”), unless the
Fundamental Change Repurchase Date falls after a Regular Record Date but on or prior to the Interest Payment Date to which such
Regular Record Date relates, in which case the Company shall instead pay the full amount of accrued and unpaid interest to Holders
of Notes of record as of such Regular Record Date, and the Fundamental Change Repurchase Price shall be equal to 100% of the principal
amount of Notes to be repurchased pursuant to this Article 9.

 

    	31

    	 

    

 

(b)          Repurchases
of Notes under this Section 9.01 shall be made, at the option of the Holder thereof, upon:

 

(i)          delivery
to the Paying Agent by a Holder of a duly completed notice (the “Fundamental Change Repurchase Notice”) in the
form set forth in Attachment 2 to the Form of Note attached hereto as Exhibit A, if the Notes are Physical Notes, or in compliance
with the Depositary’s procedures for surrendering interests in Global Notes, if the Notes are Global Notes, in each case
on or before the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date; and

 

(ii)         delivery
of the Notes, if the Notes are Physical Notes, to the Paying Agent at any time after delivery of the Fundamental Change Repurchase
Notice (together with all necessary endorsements for transfer) at the Corporate Trust Office of the Paying Agent, or book-entry
transfer of the Notes, if the Notes are Global Notes, in compliance with the procedures of the Depositary, in each case such delivery
being a condition to receipt by the Holder of the Fundamental Change Repurchase Price therefor.

 

The Fundamental Change Repurchase Notice
in respect of any Notes to be repurchased shall state:

 

(i)          in
the case of Physical Notes, the certificate numbers of the Notes to be delivered for repurchase;

 

(ii)         the
portion of the principal amount of Notes to be repurchased, which must be $2,000 or an integral multiples of $1,000 in excess thereof;
and

 

(iii)        that
the Notes are to be repurchased by the Company pursuant to the applicable provisions of the Notes and the Indenture;

 

provided, however, that if the Notes are Global
Notes, the Fundamental Change Repurchase Notice must comply with appropriate Depositary procedures.

 

Notwithstanding anything herein to the contrary,
any Holder delivering to the Paying Agent the Fundamental Change Repurchase Notice contemplated by this Section 9.01 shall have
the right to withdraw, in whole or in part, such Fundamental Change Repurchase Notice at any time prior to the close of business
on the Business Day immediately preceding the Fundamental Change Repurchase Date by delivery of a written notice of withdrawal
to the Paying Agent in accordance with Section 9.02.

 

    	32

    	 

    

 

The Paying Agent shall promptly notify the
Company of the receipt by it of any Fundamental Change Repurchase Notice or written notice of withdrawal thereof.

 

(c)          On
or before the 20th calendar day after the occurrence of the effective date of a Fundamental Change, the Company shall provide to
all Holders of Notes and the Trustee and the Paying Agent (in the case of a Paying Agent other than the Trustee) a written notice
(the “Fundamental Change Company Notice”) of the occurrence of the effective date of the Fundamental Change
and of the repurchase right at the option of the Holders arising as a result thereof. In the case of Physical Notes, such notice
shall be by first class mail or, in the case of Global Notes, such notice shall be delivered in accordance with the applicable
procedures of the Depositary. Each Fundamental Change Company Notice shall specify:

 

(i)          the
events causing the Fundamental Change;

 

(ii)         the
date of the Fundamental Change;

 

(iii)        the
last date on which a Holder may exercise the repurchase right pursuant to this Article 9;

 

(iv)        the
Fundamental Change Repurchase Price;

 

(v)         the
Fundamental Change Repurchase Date;

 

(vi)        the
name and address of the Paying Agent and the Conversion Agent, if applicable;

 

(vii)       if
applicable, the Conversion Rate and any adjustments to the Conversion Rate;

 

(viii)      that
the Notes with respect to which a Fundamental Change Repurchase Notice has been delivered by a Holder may be converted only if
the Holder withdraws the Fundamental Change Repurchase Notice in accordance with the terms of the Indenture;

 

(ix)         the
procedures that Holders must follow to require the Company to repurchase their Notes.

 

No failure of the Company to give the foregoing
notices and no defect therein shall limit the Holders’ repurchase rights or affect the validity of the proceedings for the
repurchase of the Notes pursuant to this Section 9.01.

 

At the Company’s request, the Trustee
shall give such notice in the Company’s name and at the Company’s expense; provided, however, that, in
all cases, the text of such Fundamental Change Company Notice shall be prepared by the Company.

 

    	33

    	 

    

 

(d)          Notwithstanding
the foregoing, no Notes may be repurchased by the Company on any date at the option of the Holders upon a Fundamental Change if
the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to such Fundamental
Change Repurchase Date (except in the case of an acceleration resulting from a Default by the Company in the payment of the Fundamental
Change Repurchase Price with respect to such Notes). The Paying Agent will promptly return to the respective Holders thereof any
Physical Notes held by it during the acceleration of the Notes (except in the case of an acceleration resulting from a Default
by the Company in the payment of the Fundamental Change Repurchase Price with respect to such Notes), or any instructions for book-entry
transfer of the Notes in compliance with the procedures of the Depositary shall be deemed to have been cancelled, and, upon such
return or cancellation, as the case may be, the Fundamental Change Repurchase Notice with respect thereto shall be deemed to have
been withdrawn.

 

Section 9.02         Withdrawal
of Fundamental Change Repurchase Notice. (a) A Fundamental Change Repurchase Notice
may be withdrawn (in whole or in part) by means of a written notice of withdrawal delivered to the Corporate Trust Office of the
Paying Agent in accordance with this Section 9.02 at any time prior to the close of business on the Business Day immediately preceding
the Fundamental Change Repurchase Date, specifying: 

 

(i)          
the principal amount of the Notes with respect to which such notice of withdrawal is being submitted,

 

(ii)         if
Physical Notes have been issued, the certificate number of the Note in respect of which such notice of withdrawal is being submitted,
and

 

(iii)        the
principal amount, if any, of such Note that remains subject to the original Fundamental Change Repurchase Notice, which portion
must be in principal amounts of $2,000 or an integral multiple of $1,000 in excess thereof;

 

provided, however, that if the Notes are Global
Notes, the notice must comply with appropriate procedures of the Depositary.

 

Section 9.03         Deposit
of Fundamental Change Repurchase Price. (a) The Company will deposit with the Trustee
(or other Paying Agent appointed by the Company, or if the Company is acting as its own Paying Agent, set aside, segregate and
hold in trust as provided in Section 10.03 of the Base Indenture) on or prior to 11:00 a.m., New York City time, on the Fundamental
Change Repurchase Date an amount of money sufficient to repurchase all of the Notes to be repurchased at the appropriate Fundamental
Change Repurchase Price. Subject to receipt of funds and/or Notes by the Trustee (or other Paying Agent appointed by the Company),
payment for Notes surrendered for repurchase (and not withdrawn prior to the close of business on the Business Day immediately
preceding the Fundamental Change Repurchase Date) will be made on the later of (i) the Fundamental Change Repurchase Date (provided
the Holder has satisfied the conditions in Section 9.01) and (ii) the time of book-entry transfer or the delivery of such
Note to the Trustee (or other Paying Agent appointed by the Company) by the Holder thereof in the manner required by Section 9.01
by mailing checks for the amount payable to the Holders of such Notes entitled thereto as they shall appear in the Security Register;
provided, however, that payments to the Depositary shall be made by wire transfer of immediately available funds
to the account of the Depositary or its nominee. The Trustee shall, promptly after such payment and upon written demand by the
Company, return to the Company any funds in excess of the Fundamental Change Repurchase Price.

 

    	34

    	 

    

 

(b)          If
by 11:00 a.m. New York City time, on the Fundamental Change Repurchase Date, the Trustee (or other Paying Agent appointed by the
Company) holds money sufficient to make payment on all the Notes or portions thereof that are to be repurchased on such Fundamental
Change Repurchase Date, then, with respect to the Notes that have been properly surrendered for repurchase and not validly withdrawn,
(i) such Notes will cease to be outstanding, (ii) interest will cease to accrue on such Notes (whether or not book-entry transfer
of the Notes has been made or the Notes have been delivered to the Trustee or Paying Agent, as the case may be) and (iii) all other
rights of the Holders of such Notes will terminate (other than the right to receive the Fundamental Change Repurchase Price upon
delivery or transfer of such Notes).

 

(c)          Upon
surrender of a Note that is to be repurchased in part pursuant to Section 9.01, the Company shall execute and the Trustee shall
authenticate and deliver to the Holder a new Note in an authorized denomination equal in principal amount to the unrepurchased
portion of the Note surrendered.

 

Section 9.04         Covenant
to Comply with Applicable Laws Upon Repurchase of Notes. In connection with any
repurchase offer, the Company will, if required:

 

(a)          comply
with the provisions of Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange Act that may be applicable at
the time of the offer to repurchase the Notes;

 

(b)          file
a Schedule TO or any successor or similar schedule to the extent required under the Exchange Act; and

 

(c)          otherwise
comply with all federal and state securities laws in connection with any offer by the Company to repurchase the Notes;

 

in each case, so as to permit the rights and obligations under
this Article 9 to be exercised in the time and in the manner specified in this Article 9.

[FORM OF REVERSE OF NOTE]

 

Macquarie Infrastructure Company LLC

2.875% Convertible Senior Note due 2019

 

This Note is one of a duly authorized issue
of Notes of the Company, designated as its 2.875% Convertible Senior Notes due 2019 (the “Notes”), limited to
the aggregate principal amount of $350,000,000 all issued or to be issued under and pursuant to a First Supplemental Indenture
dated as of July 15, 2014 (the “First Supplemental Indenture”), between the Company and Wells Fargo Bank, National
Association (the “Trustee”), which amends and supplements the Senior Indenture dated as of July 15 between the
Company and the Trustee (the “Base Indenture” and, as amended and supplemented by the First Supplemental Indenture
and from time to time with respect to the Notes, the “Indenture”). Reference is hereby made to the Indenture
for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company
and the Holders of the Notes.

 

In case an Event of Default, as defined
in the Indenture, shall have occurred and be continuing, the principal of, and interest on, all Notes may be declared, by either
the Trustee or Holders of at least 25% in aggregate principal amount of Notes then outstanding, and upon said declaration shall
become, due and payable, in the manner, with the effect and subject to the conditions and certain exceptions set forth in the Indenture.

 

Subject to the terms and conditions of the
Indenture, the Company will make all payments and deliveries in respect of the Fundamental Change Repurchase Price and the principal
amount on the Maturity Date, as the case may be, to the Holder who surrenders a Note to a Paying Agent to collect such payments
in respect of the Note. The Company will pay cash amounts in money of the United States that at the time of payment is legal tender
for payment of public and private debts.

 

The Company may, without the consent of
the Holders, reopen the Indenture and issue additional Notes with the same terms and with the same CUSIP number as the Notes initially
issued thereunder in an unlimited aggregate principal amount; provided that if any such additional Notes are not fungible
with the Notes initially issued thereunder for U.S. federal income tax purposes, such additional Notes shall have a separate CUSIP
number.

 

The Indenture contains provisions permitting
the Company and the Trustee in certain circumstances, without the consent of the Holders of the Notes, and in certain other circumstances,
with the consent of the Holders of not less than a majority in aggregate principal amount of the Notes at the time outstanding,
evidenced as in the Indenture provided, to execute supplemental indentures modifying the terms of the Indenture and the Notes as
described therein. It is also provided in the Indenture that, subject to certain exceptions, the Holders of a majority in aggregate
principal amount of the Notes at the time outstanding may on behalf of the Holders of all of the Notes waive any past Default or
Event of Default under the Indenture and its consequences.

 

    	A-5

    	 

    

 

No reference herein to the Indenture and
no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional,
to pay or deliver, as the case may be, the principal of, accrued and unpaid interest on, and the consideration due upon conversion
of, this Note at the place, at the respective times, at the rate and in the lawful money herein prescribed.

 

The Notes are issuable in registered form
without coupons in denominations of $2,000 principal amount and integral multiples of $1,000 in excess thereof. At the office or
agency of the Company referred to on the face hereof, and in the manner and subject to the limitations provided in the Indenture,
Notes may be converted for a like aggregate principal amount of Notes of other authorized denominations, without payment of any
service charge but, if required by the Company or Trustee, with payment of a sum sufficient to cover any transfer or similar tax
that may be imposed in connection therewith as a result of the name of the Holder of the new Notes issued upon such conversion
of Notes being different from the name of the Holder of the old Notes surrendered for such conversion.

 

The Notes are not subject to redemption
through the operation of any sinking fund or otherwise.

 

This Note shall be governed by, and construed
in accordance with, the laws of the State of New York.

 

Upon the occurrence of a Fundamental Change,
the Holder has the right, at such Holder’s option, to require the Company to repurchase for cash all of such Holder’s
Notes or any portion thereof (in principal amounts of $2,000 or integral multiples of $1,000 in excess thereof) on the Fundamental
Change Repurchase Date at a price equal to the Fundamental Change Repurchase Price.

 

Subject to the provisions of the Indenture,
the Holder hereof has the right, at its option, prior to the close of business on the second Scheduled Trading Day immediately
preceding the Maturity Date, to convert any Notes or portion thereof that is $1,000 or an integral multiple thereof, into Shares
(and cash in lieu of fractional shares) at the Conversion Rate specified in the Indenture, as adjusted from time to time as provided
in the Indenture.

 

Terms used in this Note and defined in the
Indenture are used herein as therein defined.
