consideration for possible downgrade by either of the Rating Agencies); provided that a Below Investment Grade Rating Event will not
be deemed to have occurred in respect of a particular Change of Control (and thus will not be deemed a Below Investment Grade Rating
Event for purposes of the definition of Change of Control Triggering Event) if each Rating Agency making the reduction in rating does
not publicly announce or confirm or inform the Company in writing at its request that the reduction was the result, in whole or in part,

in the absence of contingencies, entitled to vote for the election of directors (or persons performing similar functions) of such person,

by a resolution of the Board of Directors of the Company) as a replacement agency for either Moody’s, S&P, or both of them,
as the case may be.

 

“Restricted Subsidiary”

“Sale and Leaseback
Transaction” means any direct or indirect arrangement relating to property now owned or hereafter acquired whereby the
Company or a Restricted Subsidiary transfers such property to another Person and the Company or a Restricted Subsidiary leases or rents
it from such Person (other than (i) leases between the Company and a Restricted Subsidiary or between Restricted Subsidiaries, (ii) temporary
leases for a term, including renewals at the option of the lessee, of not more than three years and (iii) leases of a property executed
by the time of, or within 90 days after the latest of, the acquisition, the completion of construction or improvement, or the commencement
of commercial operation of the property).

 

“Treasury Rate” means,
with respect to any Redemption Date for any series of Notes, the yield determined by us in accordance with the following two paragraphs.

 

    5

     

    

 

The Treasury Rate shall be determined by the Company
after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors
of the Federal Reserve System), on the third business day preceding the Redemption Date based upon the yield or yields for the most recent
day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal
Reserve System designated as “Selected Interest Rates (Daily) - H.15” (or any successor designation or publication) (“H.15”)
under the caption “U.S. government securities–Treasury constant maturities–Nominal” (or any successor caption
or heading) (“H.15 TCM”). In determining the Treasury Rate, we shall select, as applicable: (1) the yield for the Treasury
constant maturity on H.15 exactly equal to the period from the Redemption Date to the Applicable Par Call Date (the “Remaining
Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields
 – one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the
Treasury constant maturity on H.15 immediately longer than the Remaining Life – and shall interpolate to the Applicable Par Call
Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or
(3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single
Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity
or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such
Treasury constant maturity from the Redemption Date.

 

If on the third business day preceding the Redemption
Date H.15 TCM is no longer published, we shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent
yield to maturity at 11:00 a.m., New York City time, on the second business day preceding such Redemption Date of the United States Treasury
security maturing on, or with a maturity that is closest to, the Applicable Par Call Date, as applicable. If there is no United States
Treasury security maturing on the Applicable Par Call Date but there are two or more United States Treasury securities with a maturity
date equally distant from the Applicable Par Call Date, one with a maturity date preceding the Applicable Par Call Date and one with
a maturity date following the Applicable Par Call Date, we shall select the United States Treasury security with a maturity date preceding
the Applicable Par Call Date. If there are two or more United States Treasury securities maturing on the Applicable Par Call Date or
two or more United States Treasury securities meeting the criteria of the preceding sentence, we shall select from among these two or
more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the
bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in
accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall
be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time,
of such United States Treasury security, and rounded to three decimal places. The Trustee shall have no obligation to determine the Treasury
Rate and shall conclusively rely upon the determination of the Treasury Rate as determined by the Company.

 

“Value”
means, with respect to a Sale and Leaseback Transaction, an amount equal to the present value of the lease payments with respect to the
term of the lease remaining on the date as of which the amount is being determined, without regard to any renewal or extension options
contained in the lease, discounted at the weighted average interest rate of all series of Securities issued pursuant to the Indenture
and having the benefit of the covenants described in Sections 5.05 and 5.06 of the Indenture (including the effective interest rate of
any original issue discount Securities) which are outstanding on the date of such Sale and Leaseback Transaction.

attached hereto. The 2032 Notes and the Trustee’s certificate of authentication shall be substantially in the form of Exhibit B
attached hereto. The Notes shall be executed on behalf of the Company by any Officer and attested by its Secretary or one of its Assistant
Secretaries. The signature of any of these Officers on the Notes may be manual or facsimile. The Notes may have notations, legends or
endorsements required by law, stock exchange rules or usage. Each Note shall be dated the date of its authentication. The Notes
shall be in denominations of $2,000 and higher integral multiples of $1,000 in excess thereof.

 

The terms and notations contained
in the Notes shall constitute, and are hereby expressly made, a part of the Indenture as supplemented by this Sixth Supplemental Indenture
and the Company and the Trustee, by their execution and delivery of this Sixth Supplemental Indenture, expressly agree to such terms
and provisions and to be bound thereby.

 

The 2025 Notes and 2032 shall
not be valid until an authorized officer of the Trustee or the Authenticating Agent authenticates the Note. The signature of the Trustee
or the Authenticating Agent on a Note shall be conclusive evidence that such Note has been duly and validly authenticated and issued
under this Indenture. The Trustee may authenticate the 2025 Notes and 2032 Notes by manual, facsimile or electronic signature. Electronically
imaged signatures such as .pdf files, faxed signatures or other electronic signatures to each Note and the authentication pages to
each Note shall have the same effect as original signatures. Each Note shall be dated the date of its authentication.

 

(b)            Each
Global Note will bear the DTC Legend.

 

Section 2.02 Paying
Agent; Depository. (a)  The Company appoints the Trustee as the initial agent of the Company for the payment of the principal
of (and premium, if any) and interest on the Notes, and the office of the Trustee located in the Borough of Manhattan, the City of New
York, be and hereby is, designated as the office or agency where the Notes may be presented for payment and where notices to or demands
upon the Company in respect of the Notes and the Indenture pursuant to which the Notes are to be issued may be served. The Company may
at any time designate additional Paying Agents or rescind the designation of any Paying Agent or approve a change in the office through
which the Paying Agent acts.

 

    7

     

    

 

(b)            The
Depository shall initially be The Depository Trust Corporation (“DTC”) and any and all successors thereto appointed
as Depository by the Company.

 

Section 2.03 Registration,
Transfer and Exchange. (a) Each Global Note will be registered in the name of the Depository or its nominee and, so long as
DTC is serving as the Depository thereof, will bear the DTC Legend.

 

(i)            Each
Global Note will be delivered to the Trustee as custodian for the Depository. Transfers of a Global Note (but not a beneficial interest
therein) will be limited to transfers thereof in whole, but not in part, to the Depository, its successors or their respective nominees,
except (y) as set forth in (iii) of this Section 2.03(a) and (z) transfers of portions thereof in the form of
Certificated Notes may be made upon request of an Agent Member (for itself or on behalf of a beneficial owner) by written notice given
to the Trustee by or on behalf of the Depository in accordance with customary procedures of the Depository and in compliance with this
Section 2.03.

 

(ii)          Agent
Members will have no rights under the Indenture with respect to any Global Note held on their behalf by the Depository, and the Depository
may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner and Holder of such Global
Note for all purposes whatsoever. Notwithstanding the foregoing, the Depository or its nominee may grant proxies and otherwise authorize
any Person (including any Agent Member and any Person that holds a beneficial interest in a Global Note through an Agent Member) to take
any action which a Holder is entitled to take under the Indenture or the Notes, and nothing herein will impair, as between the Depository
and its Agent Members, the operation of customary practices governing the exercise of the rights of a holder of any security.

 

(iii)         If
(x) the Depository notifies the Company that it is unwilling or unable to continue as Depository for a Global Note and a successor
depositary is not appointed by the Company within 90 days of such notice or (y) an Event of Default has occurred and is continuing
and the Trustee has received a written request from the Depository, the Trustee will promptly exchange each beneficial interest in the
Global Note for one or more Certificated Notes in authorized denominations having an equal aggregate principal amount registered in the
name of the owner of such beneficial interest, as identified to the Trustee by the Depository, and thereupon the Global Note will be
deemed canceled.

 

(b)            Each
Certificated Note will be registered in the name of the Holder thereof or its nominee.

 

(c)            (i)           Global
Note to Global Note. If a beneficial interest in a Global Note is transferred or exchanged for a beneficial interest in another Global
Note, the Trustee will (y) record a decrease in the principal amount of the Global Note being transferred or exchanged equal to
the principal amount of such transfer or exchange and (z) record a like increase in the principal amount of the other Global Note.
Any beneficial interest in one Global Note that is transferred to a Person who takes delivery in the form of an interest in another Global
Note, or exchanged for an interest in another Global Note, will, upon transfer or exchange, cease to be an interest in such Global Note
and become an interest in the other Global Note and, accordingly, will thereafter be subject to all transfer and exchange restrictions,
if any, and other procedures applicable to beneficial interests in such other Global Note for as long as it remains such an interest.

 

    8

     

    

 

(ii)           Global
Note to Certificated Note. If a beneficial interest in a Global Note is transferred or exchanged for a Certificated Note, the Trustee
will (y) record a decrease in the principal amount of such Global Note equal to the principal amount of such transfer or exchange
and (z) deliver one or more new Certificated Notes in authorized denominations having an equal aggregate principal amount to the
transferee (in the case of a transfer) or the owner of such beneficial interest (in the case of an exchange), registered in the name
of such transferee or owner, as applicable.

 

(iii)          Certificated
Note to Global Note. If a Certificated Note is transferred or exchanged for a beneficial interest in a Global Note, the Trustee will
(x) cancel such Certificated Note, (y) record an increase in the principal amount of such Global Note equal to the principal
amount of such transfer or exchange and (z) in the event that such transfer or exchange involves less than the entire principal
amount of the canceled Certificated Note, deliver to the Holder thereof one or more new Certificated Notes in authorized denominations
having an aggregate principal amount equal to the untransferred or unexchanged portion of the canceled Certificated Note, registered
in the name of the Holder thereof.

 

(iv)          Certificated
Note to Certificated Note. If a Certificated Note is transferred or exchanged for another Certificated Note, the Trustee will (x) cancel
the Certificated Note being transferred or exchanged, (y) deliver one or more new Certificated Notes in authorized denominations
having an aggregate principal amount equal to the principal amount of such transfer or exchange to the transferee (in the case of a transfer)
or the Holder of the canceled Certificated Note (in the case of an exchange), registered in the name of such transferee or Holder, as
applicable, and (z) if such transfer or exchange involves less than the entire principal amount of the canceled Certificated Note,
deliver to the Holder thereof one or more Certificated Notes in authorized denominations having an aggregate principal amount equal to
the untransferred or unexchanged portion of the canceled Certificated Note, registered in the name of the Holder thereof.

 

Notwithstanding anything to the contrary herein,
with respect to each series of Notes, this Section 2.03 will become effective immediately after the authentication and delivery
of Global Notes evidencing $600,000,000 aggregate principal amount of the 2025 Notes and $750,000,000 aggregate principal amount of the
2032 Notes, respectively.

3.07 or 10.06 of the Indenture) shall be $750,000,000. The Company may from time to time, without the consent of the Holders of Notes
of any series, issue additional Notes (in any such case “Additional Notes”) of any series having the same ranking
and the same interest rate, maturity and other terms as the Notes of that series, except for the issue date, the public offering price
and, in some cases, the first Interest Payment Date. Any Additional Notes of a series and the existing Notes of that series will constitute
a single series under the Indenture and all references to the relevant Notes shall include the Additional Notes unless the context otherwise
requires; provided that no Event of Default with respect to the Notes shall have occurred and be continuing; provided further that if
any such Additional Securities are not fungible with the Notes for U.S. federal income tax purposes, such Additional Securities shall
have a separate CUSIP number and shall not constitute a single series with such Notes.

 

(c)            Maturity
Date. The entire outstanding principal of the 2025 Notes shall be payable on November 14,

Rate. The rate at which the 2025 Notes shall bear interest shall be 5.400% per annum, and the
rate at which the 2032 Notes shall bear interest shall be 5.600% per annum. The date from which interest shall accrue on the Notes shall
be November 16, 2022, or the most recent Interest Payment Date to which interest has been paid or provided for. The Interest Payment
Dates for the 2025 Notes shall be May 14 and November 14 of each year, beginning May 14, 2023. The Interest Payment Dates
for the 2032 Notes shall be May 16 and November 16 of each year, beginning May 16, 2023. Interest on each series of Notes
will be computed on the basis of a 360-day year comprised of twelve 30-day months. The interest so payable, and punctually paid or duly
provided for, on any Interest Payment Date, will be paid, in immediately available funds, to the Persons in whose names the Notes (or
one or more Predecessor Securities) are registered at the close of business on the Regular Record Date for such interest, which shall
be the fifteenth calendar day, as the case may be, next preceding such Interest Payment Date. Payment of principal and interest on the
Notes will be made at the Corporate Trust Office of the Trustee or such other office or agency of the Company as may be designated for
such purpose, in such currency of the United States of America as at the time of payment is legal tender for payment of public and private
debts; provided, however, that each installment of interest and principal on the Notes may at the Company’s option
be paid in immediately available funds by transfer to an account maintained by the payee located in the United States of America.

Section 2.07 Optional
Redemption.

 

(a)            The
provisions of Article 3 of the Indenture shall apply to the Notes.

 

(b)            For
the benefit of the Holders of the Notes, a new Section 3.08 shall be added to the Indenture as follows:

 

“Section 3.08. Notice to
Holders; Redemption Price; etc.

 

(a) Prior to the Applicable Par
Call Date, the Company may redeem any series of Notes, in whole or in part, at any time and from time to time. The Redemption Price will
be equal to the greater of:

 

(i)            100%
of the principal amount of the Notes being redeemed on the Redemption Date; and

 

(ii)            the
sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming
the Notes being redeemed matured on the Applicable Par Call Date (not including the amount of accrued and unpaid interest to, but excluding,
the Redemption Date)) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 15
basis points in the case of the 2025 Notes and 25 basis points in the case of the 2032 Notes;

 

plus, in each case, accrued and unpaid
interest to, but excluding, the Redemption Date.

 

On or after the Applicable
Par Call Date, the Company may redeem any series of the Notes, in whole or in part, at any time and from time to time, at a Redemption
Price equal to 100% of the principal amount of the Notes being redeemed plus accrued and unpaid interest thereon to, but excluding, the
Redemption Date.

 

Notwithstanding the
foregoing, installments of interest on applicable Notes that are due and payable on interest payment dates falling on or prior to a Redemption
Date will be payable on the interest payment date to the registered Holders as of the close of business on the relevant record date according
to the applicable Notes and the Indenture.

 

    11

     

    

-

Notice of any redemption will be mailed
or electronically delivered (or otherwise transmitted in accordance with the DTC’s procedures) at least 10 days but not more than
60 days before the Redemption Date to each Holder of the Notes to be redeemed (with a copy to the Trustee). Once notice of redemption
is mailed, or electronically delivered (or otherwise transmitted in accordance with the DTC’s procedures) the Notes called for
redemption will become due and payable on the Redemption Date at the applicable Redemption Price, plus accrued and unpaid interest applicable
to such Notes to, but excluding, the Redemption Date.

 

The Company’s
actions and determinations in determining the Redemption Price shall be conclusive and binding for all purposes, absent manifest error.

 

In the case of a
partial redemption, selection of the Notes for redemption will be in accordance with DTC’s applicable procedures. No Notes of a
principal amount of $2,000 or less will be redeemed in part. If any Note is to be redeemed in part only, the notice of redemption that
relates to the Note will state the portion of the principal amount of the Note to be redeemed. A new Note in a principal amount equal
to the unredeemed portion of the Note will be issued in the name of the Holder of the Note upon surrender for cancellation of the original
Note. For so long as the Notes are held by DTC (or another depositary), the redemption of the Notes shall be done in accordance with
the policies and procedures of the DTC.

 

Unless the Company
defaults in payment of the Redemption Price, on and after the Redemption Date interest will cease to accrue on the Notes or portions
thereof called for redemption.

 

(c)            For
the benefit of the Holders of the Notes, a new Section 3.09 shall be added to the Indenture as follows:

 

“Section 3.09. Repurchase
of Notes Upon a Change of Control.

 

(a) If a Change of Control Triggering
Event occurs with respect to the Notes, unless the Company shall have exercised its option to redeem the Notes in full as described in
Section 3.08 of this Indenture, the Company shall be required to make an offer (the “Change of Control Offer”)
to each Holder to repurchase all or any part (equal to $2,000 principal amount or a higher integral multiple of $1,000) of such Holder’s
Notes on the terms set forth in this Section 3.09 and in the Notes. In the Change of Control Offer, the Company shall offer payment
in cash equal to 101% of the aggregate principal amount of Notes to be repurchased, plus accrued and unpaid interest, if any,
on the Notes repurchased to, but excluding, the date of repurchase (the “Change of Control Payment”). With respect
to the Notes of each series, within 30 days following any Change of Control Triggering Event or, at the Company’s option, prior
to any Change of Control, but after public announcement of the transaction that constitutes or may constitute the Change of Control,
the Company shall mail a notice to Holders of Notes of the applicable series, with a copy to the Trustee, describing the transaction
or transactions that constitute or may constitute the Change of Control Triggering Event and offering to repurchase the Notes on the
date specified in the notice, which date shall be no earlier than 30 days and no later than 60 days from the date such notice is mailed
(the “Change of Control Payment Date”). The notice will, if delivered prior to the date of consummation of the Change
of Control, state that the offer to purchase is conditioned on the Change of Control Triggering Event occurring on or prior to the Change
of Control Payment Date.

 

    12

     

    

 

(b) On the Change of Control Payment
Date, the Company shall, to the extent lawful:

 

(1) accept for
payment all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer;

 

(2) deposit
with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes properly tendered;
and

 

(3) deliver
or cause to be delivered to the Trustee the Notes properly accepted together with an Officers’ Certificate stating the aggregate
principal amount of Notes or portions of Notes being repurchased.

 

(c) The Company shall not be required
to make a Change of Control Offer upon the occurrence of a Change of Control Triggering Event if a third party makes such an offer in
the manner, at the times and otherwise in compliance with the requirements for an offer made by the Company and the third party repurchases
all Notes properly tendered and not withdrawn under its offer.

 

(d) The Company shall comply in
all material respects with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder
to the extent such laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control
Triggering Event. To the extent that the provisions of any such securities laws or regulations conflict with this Section 3.09,
the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations
under this Section 3.09 by virtue of any such conflict.

 

    13

     

    

 

Section 2.08 Reserved.

 

Section 2.09 Limitation
on Liens. For the benefit of the Holders of the Notes, a new Section 5.05 shall be added to the Indenture as follows:

 

“The Company shall not, and shall
not permit any Restricted Subsidiary to, create, assume or suffer to exist any Lien (an “Initial Lien”), other than
Permitted Liens, on any Principal Property to secure any Debt of the Company or any Restricted Subsidiary unless it has made or will
make effective provision whereby the Notes and any other debt securities of any series issued pursuant to the Indenture and having the
benefit of this Section 5.05 will be secured by such Lien equally and ratably with (or prior to) all other Debt secured by such
Lien. Any Lien created for the benefit of the Holders of the Notes and any other debt securities of any series issued pursuant to this
Indenture and having the benefit of this Section 5.05 shall provide by its terms that such Lien will be automatically released and
discharged upon the release and discharge of the applicable Initial Lien.”

 

Section 2.10 Limitation
on Sale and Leaseback Transactions. For the benefit of the Holders of the Notes, a new Section 5.06 shall be added to the Indenture
as follows:

 

“The Company shall not, and shall
not permit any Restricted Subsidiary to, enter into any Sale and Leaseback Transaction covering any Principal Property, unless (i) pursuant
to Section 5.05 of this Indenture, the Company or the Restricted Subsidiary would be entitled to incur Debt secured by a Lien on
such Principal Property in a principal amount equal to the Value of such Sale and Leaseback Transaction without equally and ratably securing
the Notes and any other debt securities of any series issued pursuant to the Indenture and having the benefit of this Section 5.06;
or (ii) the Company or any Restricted Subsidiary, during the 270 days following the effective date of the Sale and Leaseback Transaction,
applies an amount equal to the Value of such Sale and Leaseback Transaction to the voluntary retirement of long-term Debt of the Company
or any Restricted Subsidiary or to the acquisition of one or more Principal Properties.”

Zoetis Inc., a Delaware corporation (herein called
the “Company,” which term includes any successor Person under the Indenture hereinafter referred to), for value
received, hereby promises to pay to Cede & Co., or registered assigns, the principal sum of $[•], or such greater or lesser
amount set forth in the attached Schedule of Increases and Decreases in Global Note, on November 14, 2025 (the “Maturity
Date”) (except to the extent redeemed or repaid prior to the Maturity Date) and to pay interest thereon from November 16,
2022 (the “Original Issue Date”) or from the most recent Interest Payment Date to which interest has been paid
or duly provided for semi-annually at the rate of 5.400% per annum, on May 14 and November 14 (each such date, an “Interest
Payment Date”), commencing May 14, 2023, until the principal hereof is paid or made available for payment.

 

Payment of Interest. The interest so payable,
and punctually paid or made available for payment, by 10:00 a.m. New York time, on any Interest Payment Date, will, as provided in
the Indenture (defined below), be paid, in immediately available funds, to the Person in whose name this Note (or one or more predecessor
securities) is registered at the close of business on the fifteenth calendar day preceding such Interest Payment Date (the “Regular
Record Date”). Any such interest not punctually paid or duly provided for (“Defaulted Interest”)
will forthwith cease to be payable to the Holder on such Regular Record Date, and such Defaulted Interest, may be paid to the Person in
whose name this Note (or one or more predecessor securities) is registered at the close of business on a special record date (the “Special
Record Date”) for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to Holders
of Notes not less than ten days prior to such Special Record Date, or may be paid at any time in any other lawful manner not inconsistent
with requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange,
all as more fully provided in said Indenture.

 

    A-1

     

    

 

Place of Payment. Payment of principal,
premium, if any, and interest on this Note will be made at the Corporate Trust Office of the Trustee or such other office or agency of
the Company as may be designated for such purpose, in such currency of the United States of America as at the time of payment is legal
tender for payment of public and private debts; provided, however, that each installment of interest, premium, if any, and principal on
this Note may at the Company’s option be paid in immediately available funds by transfer to an account maintained by the payee located
in the United States of America.

 

Time of Payment. In any case where any Interest
Payment Date, the Maturity Date or any date fixed for redemption or repayment of the Notes shall not be a Business Day, then (notwithstanding
any other provision of the Indenture or this Note), payment of principal or interest, if any, need not be made on such date, but may be
made on the next succeeding Business Day with the same force and effect as if made on such Interest Payment Date, the Maturity Date or
the date so fixed for redemption or repayment, and no interest shall accrue in respect of the delay.

 

General. This Note is one of a duly authorized
issue of Securities of the Company, issued and to be issued in one or more series under an indenture (the “Base Indenture”),
dated as of January 28, 2013, between the Company and Deutsche Bank Trust Company Americas (herein called the “Trustee,”
which term includes any successor Trustee under the Indenture with respect to a series of which this Note is a part), as supplemented
by a Sixth Supplemental Indenture thereto, dated as of November 16, 2022 (the “Sixth Supplemental Indenture”
and, together with the Base Indenture, the “Indenture”), among the Company and the Trustee. Reference is hereby
made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company,
the Trustee and the Holders of the Securities, and of the terms upon which the Securities are, and are to be, authenticated and delivered.
In the case of any conflict between this Note and the Indenture, the provisions of the Indenture shall control. This Note is one of a
duly authorized series of Securities designated as “5.400% Senior Notes due 2025” (collectively, the “Notes”),
initially limited in aggregate principal amount to $600,000,000.

 

Further Issuance. The Company may from time
to time, without the consent of the Holders of the Notes, issue additional Securities (the “Additional Securities”)
of this series having the same ranking and the same interest rate, maturity and other terms as the Notes. Any Additional Securities of
this series and the Notes will constitute a single series under the Indenture and all references to the Notes shall include the Additional
Securities unless the context otherwise requires; provided that no Event of Default with respect to the Notes shall have occurred and
be continuing; provided further that if any such Additional Securities are not fungible with the Notes for U.S. federal income tax purposes,
such Additional Securities shall have a separate CUSIP number and shall not constitute a single series with such Notes.

 

    A-2

     

    

 

Events of Default. If an Event of Default
with respect to the Notes shall have occurred and be continuing, the principal of the Notes may be declared due and payable in the manner
and with the effect provided in the Indenture.

 

Sinking Fund. The Notes are not subject
to any sinking fund.

 

Optional Redemption. The Notes will be redeemable
at any time or from time to time prior to the Applicable Par Call Date, at the option of the Company, in whole or in part, upon not less
than 10 nor more than 60 days’ prior notice, on any date prior to their Maturity Date at a redemption price, calculated pursuant
to the Indenture, which includes accrued and unpaid interest thereon, if any, to, but excluding, the Redemption Date and assuming the
Notes matured on the Applicable Par Call Date. In the case of any partial redemption, selection of the Notes for redemption will be made
by the Trustee in accordance with the applicable procedures of DTC, in the case of Notes represented by a global security, or by the Trustee
by a method the Trustee deems to be fair and appropriate, in the case of Notes that are not represented by a global security. If any Note
is to be redeemed in part only, the notice of redemption relating to such Note shall state the portion of the principal amount thereof
to be redeemed; provided that the principal amount of any Note remaining outstanding after a redemption in part shall be $2,000 or a higher
integral multiple of $1,000. A new Note in principal amount equal to the unredeemed portion thereof will be issued in the name of the
Holder thereof upon cancellation of this Note.

 

Repurchase upon a Change of Control Triggering
Event. Upon the occurrence of a Change of Control Triggering Event with respect to the Notes, the Company shall be required to make
an offer to repurchase the Notes on the terms set forth in the Indenture.

 

Restrictive Covenants. The Indenture contains
certain covenants that, among other things, limit the ability of the Company and its Subsidiaries to create liens or the ability of the
Company to consolidate, merge or sell, transfer or lease all or substantially all of its assets.

 

Defeasance and Covenant Defeasance. The
Indenture contains provisions for defeasance at any time of (a) the entire indebtedness of the Company on this Note and (b) certain
restrictive covenants and the related Defaults and Events of Default, upon compliance by the Company with certain conditions set forth
therein, which provisions apply to this Note.

 

Modification and Waivers;
Obligations of the Company Absolute. The Indenture permits, with certain exceptions as therein provided, the amendment thereof and
the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series. Such amendment
may be effected under the Indenture at any time by the Company, and the Trustee with the consent of the Holders of not less than a majority
in aggregate principal amount of the outstanding Notes of each series affected thereby. The Indenture also contains provisions permitting
the Holders of not less than a majority in aggregate principal amount of the Securities at the time outstanding, on behalf of the Holders
of all outstanding Securities, to waive compliance by the Company with certain provisions of the Indenture. Furthermore, provisions in
the Indenture permit the Holders of not less than a majority in aggregate principal amount of the outstanding Securities of individual
series to waive on behalf of all of the Holders of Securities of such individual series certain past defaults under the Indenture and
their consequences. Any such consent or waiver shall be conclusive and binding upon the Holder of this Note and upon all future Holders
of this Note and of any Note issued upon the registration of transfer hereof or in exchange hereof or in lieu hereof, whether or not
notation of such consent or waiver is made upon this Note.

 

    A-3

     

    

 

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 the
principal of and interest on this Note at the time, place, and rate, and in the currency, herein prescribed.

 

No Recourse Against Others. No director,
officer, agent, employee, incorporator, stockholder, partner, member, or manager of the Company shall have any liability for any obligations
of the Company under any Notes or the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation.
Each Holder of the Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration
for issuance of the Notes.

 

Limitation on Suits. As set forth in, and
subject to, the provisions of the Indenture, no Holder of any Note will have any right to institute any proceeding with respect to the
Indenture or for any remedy thereunder, unless such Holder shall have previously given to the Trustee written notice of a continuing Event
of Default with respect to this series, the Holders of not less than 33% in principal amount of the outstanding Notes shall have made
written request, and offered indemnity satisfactory to the Trustee, to the Trustee to institute such proceedings as Trustee, and the Trustee
shall not have received from the Holders of a majority in principal amount of the outstanding Notes a direction inconsistent with such
request and shall have failed to institute such proceeding within 60 days; provided, however, that such limitations do not apply to a
suit instituted by the Holder hereof for the enforcement of payment of the principal of or interest on this Note on or after the respective
due dates expressed herein.

 

Authorized Denominations. The Notes are
issuable only in registered form without coupons in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof.

 

Registration of Transfer or Exchange. As
provided in the Indenture and subject to certain limitations herein and therein set forth, the transfer of this Note is registrable in
the register of the Notes maintained by the Security Registrar upon surrender of this Note for registration of transfer, at the office
or agency of the Company in any place where the principal of and interest on this Note are payable, duly endorsed by, or accompanied by
a written instrument of transfer in form satisfactory to the Company and the Security Registrar, duly executed by the Holder hereof or
his attorney duly authorized in writing, and thereupon one or more new Notes, of authorized denominations and for the same aggregate principal
