Title and Terms.

(a) There is hereby authorized a series
of Securities designated the “3.00% Senior Amortizing Notes due 2022” limited in aggregate initial principal amount
to $119,081,442, which amount shall be as set forth in any written order of the Company for authentication and delivery of Notes
pursuant to Section 3.03 of the Base Indenture.

(b) The Notes will initially be issued
as Component Notes in substantially the form of Attachment 4 to the form of Global Unit attached as Exhibit A to the Purchase Contract
Agreement, with such appropriate insertions, omissions, substitutions and other variations as are required or permitted by the
Indenture, and may have such letters, numbers or other marks of identification and such legends or endorsements placed thereon

    	 	5	 

     

    

(c) Holders of Units have the right to
separate such Units into their constituent parts, consisting of Separate Purchase Contracts and Separate Notes, during the times,
and under the circumstances, described in Section 2.03 of the Purchase Contract Agreement. Upon separation of any Unit into its
constituent parts, (i) if such Unit is a Global Unit, the Separate Notes will initially be evidenced by a Global Note (the “Global
Note”) in substantially the form of Exhibit A hereto, which is incorporated into and shall be deemed a part of this Supplemental
Indenture, and deposited with the Trustee as custodian for the Depositary and registered in the name of the Depositary or its nominee,
or (ii) if such Unit is in definitive, registered form, the Separate Notes will be evidenced by Certificated Notes in substantially
the form of Exhibit A hereto, in each case, as provided in Section 2.03 of the Purchase Contract Agreement. Following separation
of any Unit into its constituent Separate Note and Separate Purchase Contract, the Separate Notes are transferable independently
from the Separate Purchase Contracts. In addition, Separate Notes can be recombined with Separate Purchase Contracts to recreate
Units, as provided for in Section 2.04 of the Purchase Contract Agreement.

(d) The Global Note representing Separate
Notes (which shall initially have a balance of zero Notes) shall be registered in the name of Cede & Co., as nominee of the
Depositary and delivered to the Trustee, as custodian for the Depositary. Members of, or participants in, the Depositary (“Agent
Members”) shall have no rights under the Indenture with respect to any Global Note (or any Global Unit in the case of

owner of the Global Note (or such Global Unit) for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall
prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy

customary practices governing the exercise of the rights of any Holder.

Section 2.02.         
Installment Payments. (a) The Company shall pay installments on the Notes (each such payment, an “Installment
Payment”) in cash at the place, at the respective times and in the manner provided in the Notes. Installment Payments
shall be paid to the Person in whose name a Note is registered at the close of business on the Regular Record Date corresponding
to such Installment Payment Date. The Company has initially designated the Trustee as its Paying Agent and Security Registrar in
respect of the Notes and its agency in New York, New York as a place where Notes may be presented for payment or for registration
of transfer. The Company may, however, change the Paying Agent or Security Registrar for the Notes without prior notice to the
Holders thereof, and the Company may act as Paying Agent or Security Registrar.

(b) On the first Installment Payment Date
occurring on July 30, 2019, the Company shall pay, in cash, an Installment Payment with respect to each Note in an amount equal
to $0.80833 per Note, and on each Installment Payment Date thereafter, the Company shall pay, in cash, equal quarterly Installment
Payments with respect to each Note in an amount equal to $0.75000 per Note; provided that, in respect of any Certificated

to each Note as set forth in the schedule below:

(d) Each Installment Payment for any Installment
Payment Period shall be computed on the basis of a 360-day year of twelve 30-day months. If an Installment Payment is payable for
any period shorter or longer than a full Installment Payment Period, such Installment Payment shall be computed on the basis of
the actual number of days elapsed per 30-day month. Furthermore, if any date on which an Installment Payment is payable is not
a Business Day, then payment of the Installment Payment on such date shall be made on the next succeeding day that is a Business
Day, and without any interest or other payment in respect of any such delay.

Any Installment Payment on any Note which
is payable, but is not punctually paid or duly provided for, on any Installment Payment Date (herein called “Defaulted
Installment Payment”) 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 Installment Payment 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 Installment Payment to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered
at the close of business on a Special Record Date for the payment of such Defaulted Installment Payment, which shall be fixed in
the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Installment Payment proposed to
be paid on each Note 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 Installment Payment 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 Installment Payment as in this Clause provided. Thereupon the Trustee
shall fix a Special Record Date for the payment of such Defaulted Installment Payment 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 Installment Payment and the Special
Record Date therefor to be mailed, first-class postage prepaid, to each Holder of Notes at his address as it appears in the Security
Register, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Installment
Payment and the Special Record Date therefor having been so mailed, such Defaulted Installment Payment shall be paid to the Persons
in whose names the Notes (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).

    	 	7	 

     

    

(2) The Company may make payment of any
Defaulted Installment Payment on the Notes in any other lawful manner not inconsistent with the requirements of any securities
exchange on which such Notes 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.

Section 2.03.         
Maturity Date. The date on which the final Installment Payment on the Notes shall be due, unless the Notes are accelerated
pursuant to the terms hereof or otherwise paid prior to maturity in connection with a Holder’s exercise of the Repurchase
Right, shall be the Maturity Date.

Section 2.04.         
Right to Exchange or Register a Transfer. (a) The Company shall not be required to exchange or register a transfer
of any Note if the Holder thereof has exercised his, her or its right, if any, to require the Company to repurchase such Note in
whole or in part, except the portion of such Note not required to be repurchased.

(b) For purposes of any Note that constitutes
part of a Unit, Section 3.05 of the Base Indenture (as modified by this Supplemental Indenture) shall be subject to the provisions
of the Purchase Contract Agreement.

amended and restated in its entirety by the following:

“Section 5.01 Events of Default.

“Event of Default”,
wherever used herein with respect to Notes, means any one of the following events (whatever the reason for such Event of Default
and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order
of any court or any order, rule or regulation of any administrative or governmental body):

    	 	9	 

     

    

(3) failure by the Company to give
notice of a Fundamental Change pursuant to Section 4.07 of the Purchase Contract Agreement when due and continuance of such failure
for a period of five Business Days; or

(4) default in the performance,
or breach, of any covenant or warranty of the Company in this Indenture (other than a covenant or warranty a default in whose performance
or whose breach is elsewhere in this Section specifically dealt with or which has expressly been included in this Indenture solely
for the benefit of series of Notes other than the Notes), 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 Notes a written notice specifying such default or breach and requiring it
to be remedied and stating that such notice is a “Notice of Default” hereunder; or

(5) 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 case or proceeding
under any applicable Federal or State bankruptcy, insolvency, reorganization or other similar law or (B) a decree or order adjudging
the Company a bankrupt or insolvent, or approving as properly filed a petition seeking reorganization, arrangement, adjustment
or composition of or in respect of the Company under any applicable Federal or State law, or appointing a custodian, receiver,
liquidator, assignee, trustee, sequestrator or other similar official of the Company or of any substantial part of its property,
or ordering the winding up or liquidation of its affairs, and the continuance of any such decree or order for relief or any such
other decree or order unstayed and in effect for a period of 60 consecutive days; or

(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, or 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 or State bankruptcy,
insolvency, reorganization or other similar law or to the commencement of any bankruptcy or insolvency case or proceeding against
it, or the filing by it of a petition or answer or consent seeking reorganization or relief under any applicable Federal or State
law, or the consent by it to the filing of such petition or to the appointment of or taking possession by a custodian, receiver,
liquidator, assignee, trustee, sequestrator or other similar official of the Company or of any substantial part of its property,
or the making by it of an assignment for the benefit of creditors, or the admission by it in writing of its inability to pay its
debts generally as they become due, or the taking of corporate action by the Company in furtherance of any such action.

Section 5.02 Acceleration of Maturity;
Rescission and Annulment.

If an Event of Default with respect
to Notes 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 Notes may declare the Notes 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 the Repurchase Price shall become immediately
due and payable. If an Event of Default described in Section 5.01(5) or Section 5.01(6) occurs and is continuing,
the Repurchase Price on all the Notes will become and be immediately due and payable without any declaration or other act on the
part of the Trustee or any Holders.

    	 	10	 

     

    

At any time after such a declaration
of acceleration with respect to Notes 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 Notes,
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 Installment Payments
on all Notes,

(B) the Repurchase Price on any
Notes which have become due otherwise than by such declaration of acceleration and any interest thereon at the rate or rates prescribed
therefor in such Notes,

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

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

(2) all Events of Default with
respect to Notes, other than the non-payment of the Repurchase Price of Notes 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 Installment Payments on any Note when such Installment Payment becomes due and payable and such default continues for a
period of 30 days, or

(2) default is made in the Repurchase
Price of any Note at the Maturity thereof,

the Company will, upon demand of
the Trustee, pay to it, for the benefit of the Holders of such Notes, the whole amount then due and payable on such Notes for the
Repurchase Price and Installment Payments and, to the extent that payment of such interest shall be legally enforceable, interest
on any overdue Repurchase Price or Installment Payments, at the rate or rates prescribed therefor in such Notes, and, in addition
thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel.

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

    	 	11	 

     

    

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 Notes), 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 Notes 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 Notes.

All rights of action and claims
under this Indenture or the Notes may be prosecuted and enforced by the Trustee without the possession of any of the Notes 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 Notes in respect of which such judgment has been recovered.

Section 5.06 Application of Money
Collected.

Any money collected by the Trustee
pursuant to this Article shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the
distribution of such money on account of Repurchase Price or any Installment Payment, upon presentation of the Notes 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 Repurchase Price and Installment Payments on the Notes, ratably, without preference or priority of any
kind, according to the amounts due and payable on such Notes for Repurchase Price and Installment Payments; and

THIRD: To the Company.

    	 	12	 

     

    

Section 5.07 Limitation on Suits.

No Holder of any Note 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 Notes;

(2) the Holders of not less than
25% in principal amount of the Outstanding Notes 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 reasonable indemnity satisfactory to it 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 Notes; 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 Repurchase Price and Installment Payments.

Notwithstanding any other provision
in this Indenture, the Holder of any Note shall have the right, which is absolute and unconditional, to receive payment of the
Repurchase Price and Installment Payments (subject to Section 3.07) on such Note on the respective Stated Maturities expressed
in such Note 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 Notes 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.

    	 	13	 

     

    

Section 5.11 Delay or Omission
Not Waiver.

No delay or omission of the Trustee
or of any Holder of any Notes 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 Notes 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 Notes, provided
that

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

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

(3) subject to the provisions of
Section 6.01, the Trustee shall have the right to decline to follow any such direction if the Trustee in good faith shall,
by a Responsible Officer or Officers of the Trustee, determine that the proceedings so directed would involve the Trustee in personal
liability.

Section 5.13 Waiver of Past Defaults.

The Holders of not less than a
majority in principal amount of the Outstanding Notes may on behalf of the Holders of all the Notes waive any past default hereunder
with respect to such Notes and its consequences, except a default

(1) in the payment of the Repurchase Price
or any Installment Payment on any Note, 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
Note 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 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 apply to any suit instituted by the Trustee, to any suit instituted by any Holders
of the Notes, or group of Holders of the Notes, holding in the aggregate more than 10% of principal amount of the Outstanding Notes,
or to any suit instituted by any Holder of the Outstanding Notes for the enforcement of the payment of the Installment Payments
on any Outstanding Notes held by such Holder, on or after the respective due dates expressed in such Outstanding Notes, and provided,
further, 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.

    	 	14	 

     

    

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.”

to pay the Repurchase Price and Installment Payments so becoming due until such sums shall be paid to such Persons or otherwise

be amended and restated in its entirety with the following:

    	 	19	 

     

    

“Section 14.01 Company’s
Option to Effect Defeasance or Covenant Defeasance.

The Company may elect, at its option
by Board Resolution at any time, to have either Section 14.02 or Section 14.03 applied to the Outstanding Notes,
upon compliance with the conditions set forth below in this Article XIV.

Section 14.02 Defeasance and Discharge.

Upon the Company’s exercise

shall be deemed to have been discharged from its obligations with respect to the Outstanding Notes as provided in this Section
on and after the date the conditions set forth in Section 14.04 are satisfied (hereinafter called “Defeasance”).
For this purpose, such Defeasance means that the Company shall be deemed to have paid and discharged the entire indebtedness represented

are concerned (and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging the same), subject
to the following which shall survive until otherwise terminated or discharged hereunder: (1) the rights of Holders of Notes to
receive, solely from the trust fund described in Section 14.04 and as more fully set forth in such Section, payments
in respect of the principal and Installment Payments on such Notes when payments are due, (2) the Company’s obligations with

powers, trusts, duties and immunities of the Trustee hereunder and (4) this Article XIV. Subject to compliance with this
Article XIV, the Company may exercise its option provided in Section 14.01 to have this Section 14.02 applied
to the Outstanding Notes notwithstanding the prior exercise of its option provided in Section 14.01 to have Section
14.03 applied to the Outstanding Notes. Following a Defeasance, payment of such Notes may not be accelerated because of an
Event of Default.

Section 14.03 Covenant Defeasance.

Upon the Company’s exercise
of the option provided in Section 14.01 to have this Section 14.03 applied to the Outstanding Notes, (1) the Company
shall be released from its obligations under any covenants provided pursuant to Section 3.01(17) or Section 9.01(2)
with respect to the Notes, Section 8.01 and Article XIII, as applicable, and (2) the occurrence of any event specified
in Section 5.01(4) (with respect to Section 8.01, any such covenants provided pursuant to Section 3.01(17)
or Section 9.01(2) and Article XIII), shall be deemed not to be or result in an Event of Default, in each case with
respect to the Outstanding Notes as provided in this Section on and after the date the conditions set forth in Section 14.04
are satisfied (hereinafter called “Covenant Defeasance”). For this purpose, such Covenant Defeasance means that
the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any
covenants added for the benefit of the Notes pursuant to any such specified Section (to the extent so specified in the case of
Section 5.01(4)), whether directly or indirectly by reason of any reference elsewhere herein to any such Section or by reason
of any reference in any such Section to any other provision herein or in any other document, but the remainder of this Indenture
and the Notes shall be unaffected thereby.

Section 14.04 Conditions to Defeasance
or Covenant Defeasance.

The following shall be the conditions
to application of either Section 14.02 or Section 14.03 to the Outstanding Notes:

    	 	20	 

     

    

(1) The Company shall irrevocably
have deposited or caused to be deposited with the Trustee 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 Outstanding Notes, (A) U.S. Dollars
in an amount, or (B) U.S. Government Obligations that through the scheduled payment of Installment Payments 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, in each case 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 any such other qualifying trustee) to pay and discharge, the principal of and Installment Payments on the Notes on
the respective Stated Maturities, in accordance with the terms of this Indenture and the Notes. As used herein, “U.S.
Government Obligation” means (x) any security that is (i) a direct obligation of the United States of America for the
payment of which full faith and credit of the United States of America is pledged or (ii) an obligation of a Person controlled
or supervised by and acting as an agency or instrumentality of the United States of America the payment of which is unconditionally
guaranteed as a full faith and credit obligation by the United States of America, which, in either case (i) or (ii), is not callable
or redeemable at the option of the issuer thereof, and (y) any depositary receipt issued by a bank (as defined in Section 3(a)(2)
of the Securities Act of 1933, as amended) as custodian with respect to any U.S. Government Obligation specified in Clause (x)
and held by such custodian for the account of the holder of such depositary receipt, or with respect to any specific payment of
Installment Payment on any such U.S. Government Obligation, 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 depositary receipt from any amount received by the custodian
in respect of the U.S. Government Obligation or the specific payment of Installment Payment evidenced by such depositary receipt.

(2) In the case of an election
under Section 14.02, the Company shall have delivered to the Trustee an Opinion of Counsel stating that (A) the Company
has received from, or there has been published by, the Internal Revenue Service a ruling or (B) since the date first set forth
hereinabove, there has been a change in the applicable Federal income tax law, in either case (A) or (B) to the effect that, and
based thereon such opinion shall confirm that, the Holders of the Outstanding Notes will not recognize gain or loss for Federal
income tax purposes as a result of the deposit, Defeasance and discharge to be effected with respect to the Notes and will be subject
to Federal income tax on the same amount, in the same manner and at the same times as would be the case if such deposit, Defeasance
and discharge were not to occur.

(3) In the case of an election
under Section 14.03, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders
of the Outstanding Notes will not recognize gain or loss for Federal income tax purposes as a result of the deposit and Covenant
Defeasance to be effected with respect to the Notes and will be subject to Federal income tax on the same amount, in the same manner
and at the same times as would be the case if such deposit and Covenant Defeasance were not to occur.

(4) The Company shall have delivered
to the Trustee an Officer’s Certificate to the effect that the Notes, if then listed on any securities exchange, will not
be delisted as a result of such deposit.

(5) No Event of Default or event
that (after notice or lapse of time or both) would become an Event of Default shall have occurred and be continuing at the time
of such deposit or, with regard to any Event of Default or any such event specified in Sections 5.01(5) and (6),
at any time on or prior to the 90th day after the date of such deposit (it being understood that this condition shall not be deemed
satisfied until after such 90th day).

    	 	21	 

     

    

(6) Such Defeasance or Covenant
Defeasance shall not cause the Trustee to have a conflicting interest within the meaning of the Trust Indenture Act (assuming all
Notes are in default within the meaning of such Act).

(7) 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.

(8) The Company shall have delivered
to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent with respect
to such Defeasance or Covenant Defeasance have been complied with.

(9) Such Defeasance or Covenant
Defeasance shall not result in the trust arising from such deposit constituting an investment company within the meaning of the
Investment Company Act of 1940, as amended, unless such trust shall be qualified under such Act or exempt from regulation thereunder.

Section 14.05 Deposited
Money and U.S. Government Obligations to be Held in Trust; Other Miscellaneous Provisions.

Subject to Section 10.03,
all money and U.S. Government Obligations (including the proceeds thereof) deposited with the Trustee or other qualifying trustee
(solely for purposes of this Section and Section 14.06, the Trustee and any such other trustee are referred to collectively
as the “Trustee”) pursuant to Section 14.04 in respect of the Notes shall be held in trust and applied
by the Trustee, in accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through any
such Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Holders of Notes,
of all sums due and to become due thereon in respect of principal or Installment Payments, but money so held in trust 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 U.S. Government Obligations deposited pursuant
to Section 14.04 or the principal or Installment Payments received in respect thereof other than any such tax, fee or other
charge that by law is for the account of the Holders of Outstanding Notes.

Anything in this Article XIV
to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon Company Request any money
or U.S. Government Obligations held by it as provided in Section 14.04 with respect to Notes that, 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 that would then be required to be deposited to effect an equivalent Defeasance or Covenant Defeasance
with respect to the Notes.

Section 14.06 Reinstatement.

If the Trustee or the Paying Agent
is unable to apply any money in accordance with this Article XIV with respect to the Notes 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 Notes shall be revived and reinstated as though no deposit had occurred pursuant to this
Article XIV with respect to Notes until such time as the Trustee or Paying Agent is permitted to apply all money held in
trust pursuant to Section 14.05 with respect to Notes in accordance with this Article XIV; provided, however,
that if the Company makes any payment of principal or any Installment Payment on any Note following the reinstatement of its obligations,
the Company shall be subrogated to the rights of the Holders of Notes to receive such payment from the money so held in trust.”

an Acquisition Termination Redemption of, the Purchase Contracts pursuant to the terms of the Purchase Contract Agreement, then
each Holder of Notes (whether any such Note is a Separate Note or constitutes part of a Unit) shall have the right (the “Repurchase
Right”) to require the Company to repurchase some or all of its Notes for cash at the Repurchase Price per Note to be
repurchased on the Repurchase Date, pursuant to Section 11.03. The Company shall not be required to repurchase a portion of a Note.
Holders shall not have the right to require the Company to repurchase any or all of such Holders’ Notes in connection with
any Early Settlement (as such term is defined in the Purchase Contract Agreement) of such Holders’ Purchase Contracts at
the Holders’ option pursuant to the terms of the Purchase Contract Agreement.

Section 11.02.     
Early Mandatory Settlement Notice and Acquisition Redemption Notice. If the Company elects to exercise its Early

of the Early Mandatory Settlement Notice or Acquisition Redemption Notice, as the case may be, delivered pursuant to the Purchase
Contract Agreement.

Section 11.03.     
Procedures for Exercise.

(a) To exercise the Repurchase Right, a
Holder must deliver, on or prior to the close of business on the Business Day immediately preceding the Repurchase Date, the Notes
to be repurchased (or the Units that include the Notes to be repurchased, if (x) the Early Mandatory Settlement Date or Acquisition
Redemption Settlement Date, as the case may be, occurs on or after the Repurchase Date and (y) the relevant Notes have not been
separated from the Units), together with a duly completed written Repurchase Notice, in each case, subject to and in accordance
with applicable procedures of the Depositary, unless the Notes are not in the form of a Global Note (or the Units are not in the
form of Global Units, as the case may be), in which case such Holder must deliver the Notes to be repurchased (or the Units that
include the Notes to be repurchased, if (i) the Early Mandatory Settlement Date or Acquisition Redemption Settlement Date, as the
case may be, occurs on or after the Repurchase Date and (ii) the Notes have not been separated from the Units), duly endorsed for
transfer to the Company, together, in either case, with a Repurchase Notice, to the Paying Agent.

(b) The Repurchase Notice must state the
following:

(i) if Certificated Notes (or Units)
have been issued, the certificate numbers of the Notes (or Units), or if the Notes (or Units) are in the form of a Global Note
(or a Global Unit), the Repurchase Notice must comply with appropriate procedures of the Depositary;

    	 	23	 

     

    

(ii) the number of Notes to be repurchased;
and

(iii) that the Notes are to be repurchased
by the Company pursuant to the applicable provisions of the Notes and this Article XI.

(c) In the event that the Company exercises
its Early Mandatory Settlement Right or in the event that an Acquisition Termination Redemption occurs with respect to Purchase
Contracts that are a component of Units and the Early Mandatory Settlement Date or Acquisition Redemption Settlement Date, as the
case may be, occurs prior to the Repurchase Date, upon such Early Mandatory Settlement Date or Acquisition Redemption Settlement
Date, as the case may be, the Company shall execute and the Trustee shall authenticate on behalf of the holder of the Units and
deliver to such holder, at the expense of the Company, Separate Notes in the same form and in the same number as the Notes comprising
part of the Units.

Section 11.04.     
Withdrawal of Repurchase Notice.

(a) A Holder may, subject to and in accordance
with applicable procedures of the Depositary, in the case of a Global Note or Global Unit, withdraw any Repurchase Notice (in whole
or in part) by a written, irrevocable notice of withdrawal delivered to the Paying Agent, with a copy to the Trustee and the Company,
on or prior to the close of business on the Business Day immediately preceding the Repurchase Date.

(b) The notice of withdrawal must state
the following:

(i) if Certificated Notes (or Units)
have been issued, the certificate numbers of the withdrawn Notes (or Units), or if the Notes (or Units) are in the form of a Global
Note (or a Global Unit), the notice of withdrawal must comply with appropriate Depositary procedures;

(ii) the number of the withdrawn
Notes; and

(iii) the number of Notes, if any,
that remain subject to the Repurchase Notice.

Section 11.05.     
Effect of Repurchase. (a) The Company shall be required to repurchase the Notes with respect to which the Repurchase
Right has been validly exercised and not withdrawn on the Repurchase Date. To effectuate such repurchase, the Company shall deposit
immediately available funds with the Paying Agent, on or prior to 11:00 a.m., New York City time, on the Repurchase Date, in an
amount or amounts sufficient to pay the Repurchase Price with respect to those Notes for which the Repurchase Right has been exercised.
A Holder electing to exercise the Repurchase Right shall receive payment of the Repurchase Price on the later of (i) the Repurchase
Date and (ii) the time of book-entry transfer or the delivery of the Notes (or Units, as applicable).

(b) If the Paying Agent holds money on
the Repurchase Date sufficient to pay the Repurchase Price with respect to those Notes for which the Repurchase Right has been
exercised, then (i) such Notes shall cease to be outstanding and interest shall cease to accrue thereon (whether or not book-entry
transfer of the Notes or Units, as applicable, is made or whether or not the Notes or Units, as applicable, are delivered as required
herein), and (ii) all other rights of the Holder shall terminate (other than the right to receive the Repurchase Price and, if
the Repurchase Date falls between a Regular Record Date and the corresponding Installment Payment Date, the related Installment
Payment).

    	 	24	 

     

    

(c) In connection with any repurchase offer
pursuant to this Article XI, the Company shall, if required, comply with the provisions of the tender offer rules under the Exchange
Act that may then be applicable.

(d) Notwithstanding anything to the contrary
herein, no Notes may be repurchased at the option of Holders if the principal amount thereof has been accelerated, and such acceleration
has not been rescinded, on or prior to the Repurchase Date (except in the case of an acceleration resulting from a default by the
Company of the payment of the Repurchase Price with respect to such Notes).

Any Installment Payment on any Note which is payable, but

of any Defaulted Installment Payment to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered
at the close of business on a Special Record Date for the payment of such Defaulted Installment Payment, which shall be fixed in
the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Installment Payment proposed to
be paid on each Note 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 Installment Payment 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 Installment Payment as in this Clause provided. Thereupon the Trustee
shall fix a Special Record Date for the payment of such Defaulted Installment Payment 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 Installment Payment and the Special
Record Date therefor to be mailed, first-class postage prepaid, to each Holder of Notes at his address as it appears in the Security
Register, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Installment
Payment and the Special Record Date therefor having been so mailed, such Defaulted Installment Payment shall be paid to the Persons
in whose names the Notes (or their respective Predecessor Securities) are registered at the close of business on such Special Record
Date and shall no longer be payable pursuant to the following Clause (2).

(2) The Company may make payment of any
Defaulted Installment Payment on the Notes in any other lawful manner not inconsistent with the requirements of any securities
exchange on which such Notes 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.

The Notes shall not be subject to redemption at the option
of the Company. However, a Holder shall have the right to require the Company to repurchase some or all of its Notes for cash at
the Repurchase Price per Note and on the Repurchase Date, upon the occurrence of certain events and subject to the conditions set
forth in the Indenture.

This Note is not entitled to the benefit of any sinking fund.
The Indenture contains provisions for satisfaction and discharge, legal defeasance and covenant defeasance of this Note upon compliance
by the Company with certain conditions set forth therein, which provisions apply to this Note.

If an Event of Default with respect to the Notes shall occur
and be continuing, then either the Trustee or the Holders of not less than 25% in principal amount of the Notes then outstanding
may declare the Repurchase Price and all Installment Payments on this Note, to be due and payable immediately, in the manner, subject
to the conditions and with the effect provided in the Indenture.

The Indenture permits, with certain exceptions as therein
provided, the Company and the Trustee, with the consent of the Holders of not less than a majority in principal amount of the Notes
at the time outstanding, to execute supplemental indentures for certain purposes as described therein.

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 the Repurchase Price, if applicable, of and
all Installment Payments on this Note at the time, place and rate, and in the coin or currency, herein and in the Indenture prescribed.

The Notes are originally being issued as part of the 6.00%
Tangible Equity Units (the “Units”) issued by the Company pursuant to that certain Purchase Contract Agreement,
dated as of April 23, 2019, between the Company and U.S. Bank N.A., as Purchase Contract Agent, as Trustee and as attorney-in-fact
for the holders of Purchase Contracts from time to time (the “Purchase Contract Agreement”). Holders of the
Units have the right to separate such Units into their constituent parts, consisting of Separate Purchase Contracts (as defined
in the Purchase Contract Agreement) and Separate Notes, during the times, and under the circumstances, described in the Purchase
Contract Agreement. Following separation of any Unit into its constituent Separate Note and Separate Purchase Contract, the Separate
Notes are transferable independently from the Separate Purchase Contracts. In addition, Separate Notes can be recombined with Separate
Purchase Contracts to recreate Units, as provided for in the Purchase Contract Agreement. Reference is hereby made to the Purchase
Contract Agreement for a more complete description of the terms thereof applicable to the Units.

therein set forth, the transfer of this Note shall be registered on the Security Register of the Company, upon due presentation
of this Note for registration of transfer at the office or agency of the Company in the Borough of Manhattan, The City of New York,
duly endorsed by, or accompanied by a written instrument or instruments of transfer in form satisfactory to the Company and the
Trustee duly executed by, the Holder hereof or by his attorney duly authorized in writing, and thereupon the Company shall execute

and for a like aggregate principal amount.

The Notes are initially issued in registered, global form
without coupons in denominations equal to $8.62909 initial principal amount and integral multiples in excess thereof.

The Company or Trustee 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 of this Note.
No service charge shall be made for any such transfer or for any exchange of this Note as contemplated by the Indenture.

The Company, the Trustee and any agent of the Company or
the Trustee may deem and treat the Person in whose name this Note is registered upon the Security Register for the Notes as the
absolute owner of this Note (whether or not this Note shall be overdue and notwithstanding any notice of ownership or writing thereon
made by anyone other than the Registrar) for the purpose of receiving payment of or on account of the principal of and, subject
to the provisions of the Indenture, interest on this Note and for all other purposes; and neither the Company nor the Trustee nor
any agent of the Company or the Trustee shall be affected by any notice to the contrary.

This Note and the Indenture and any claim, controversy
or dispute arising under or related thereto shall be governed by and construed in accordance with the laws of the State of New
York. 

Capitalized terms used but not defined in this Note shall
have the meanings ascribed to such terms in the Indenture.

No recourse shall be had for the payment of any Installment
Payment on this Note, or for any claim based hereon, or upon any obligation, covenant or agreement of the Company in the Indenture,
against any incorporator, stockholder, officer or director, past, present or future of the Company or of any predecessor or successor,
either directly or through the Company or any predecessor or successor, whether by virtue of any constitution, statute or rule
of law, or by the enforcement of any assessment of penalty or otherwise; and all such personal liability is expressly released
and waived as a condition of, and as part of the consideration for, the issuance of this Note.

The Company and each Beneficial Holder agrees, for United
States federal income tax purposes, to treat the Notes as indebtedness of the Company.

In the event of any inconsistency between the provisions
of this Note and the provisions of the Indenture, the Indenture shall prevail.
