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 Fifth Supplemental Indenture and the Company and the Trustee, by their execution and delivery of this Fifth Supplemental Indenture, expressly agree to such terms and provisions and to be bound thereby. 

(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. 

(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 

  
 7 













 
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. 

(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


  
 8 













 
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 $750,000,000 aggregate principal amount of the 2030 Notes and $500,000,000 aggregate principal amount of the 2050 Notes, respectively.

Notice to Holders; Redemption Price; etc. 
 (a) At any time and from time to time prior to the Applicable Par Call
Date, the Notes of each series will be redeemable, as a whole or in part, at the Company’s option, on at least 10 days, but not more than 60 days, prior notice mailed to the registered address of each holder of the Notes of the applicable
series, or by the Trustee for transmission to the Depository or its nominee at the written request and at the expense of the Company or such other notice method in accordance with the Indenture as determined by a resolution of the Board of Directors
of the Company or a certificate executed by 

  
 10 













 
certain Officers of the Company, at a Redemption Price equal to the greater of (i) 100% of principal amount of the Notes to be redeemed on the Redemption Date, and (ii) the sum of the
present values of the remaining scheduled payments of interest and principal thereon on the Redemption Date as if such series of Notes matured on the Applicable Par Call Date (not including the amount of accrued and unpaid interest to, but
excluding, the Redemption Date) discounted to the Redemption Date on a semiannual basis, assuming a 360-day year consisting of twelve 30-day months, at the Treasury
Rate, as determined by the Reference Treasury Dealer, plus 25 basis points in the case of the 2030 Notes and 30 basis points in the case of the 2050 Notes, plus, in the case of either (i) or (ii), accrued and unpaid interest to,
but excluding, the Redemption Date; 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; provided further, however, that if the Company
redeems the 2030 Notes or the 2050 Notes on or after the Applicable Par Call Date with respect to such Notes, the Redemption Price will equal 100% of the principal amount of the applicable Notes to be redeemed plus accrued and unpaid interest on the
amount being redeemed to, but excluding, the Redemption Date. 
 (b) On and after the Redemption Date for the Notes of any
series, interest will cease to accrue on the Notes of such series or any portion thereof called for redemption, unless the Company defaults in the payment of the Redemption Price and accrued and unpaid interest. By 10:00 a.m. New York City time on,
or before, the Redemption Date for the Notes of such series, the Company will deposit with a Paying Agent, or the Trustee, funds sufficient to pay the Redemption Price of and accrued and unpaid interest on the Notes to be redeemed on such date. If
less than all of the Notes of a series are to be redeemed, the Notes of that series to be redeemed will be selected 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.” 

(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 

  
 11 













 
“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. 

(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.


  
 12 













 (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. 
 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.”

ISIN: US98978V AS25 
 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 May 15, 2030 (the “Maturity Date”) (except
to the extent redeemed or repaid prior to the Maturity Date) and to pay interest thereon from May 12, 2020 (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 2.000% per annum, on May 15 and November 15 (each such date, an “Interest Payment Date”), commencing November 15, 2020, 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.

 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. 

  
 A-1 













 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 Fifth Supplemental Indenture thereto, dated as of May 12, 2020 (the “Fifth 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 “2.000% Senior Notes due 2030” (collectively, the “Notes”), initially limited in aggregate principal
amount to $750,000,000. 
 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. 
 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


  
 A-2 













 
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. 
 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. 

  
 A-3 













 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 amount, will be issued to the designated transferee or transferees. 

As provided in the Indenture and subject to certain limitations herein and therein set forth, the Notes are exchangeable for a like aggregate
principal amount of Notes of different authorized denominations, as requested by the Holders surrendering the same. 
 No service charge
shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. 

Prior to due presentment of this Note for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may
treat the Holder as the owner hereof for all purposes (except with respect to certain payments of Defaulted Interest), whether or not this Note be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the
contrary. 
 Defined Terms. All terms used in this Note, which are defined in the Indenture and are not otherwise defined herein,
shall have the meanings assigned to them in the Indenture. 
 Governing Law. This Note shall be governed by and construed in
accordance with the laws of the State of New York.

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 Fifth Supplemental Indenture thereto, dated as of May 12, 2020 (the “Fifth 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 “3.000% Senior Notes due 2050” (collectively, the “Notes”), initially limited in aggregate principal amount to
$500,000,000. 
 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. 
 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


  
 B-2 













 
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. 
 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. 

  
 B-3 













 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 amount, will be issued to the designated transferee or transferees. 

As provided in the Indenture and subject to certain limitations herein and therein set forth, the Notes are exchangeable for a like aggregate
principal amount of Notes of different authorized denominations, as requested by the Holders surrendering the same. 
 No service charge
shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. 

Prior to due presentment of this Note for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may
treat the Holder as the owner hereof for all purposes (except with respect to certain payments of Defaulted Interest), whether or not this Note be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the
contrary. 
 Defined Terms. All terms used in this Note, which are defined in the Indenture and are not otherwise defined herein,
shall have the meanings assigned to them in the Indenture. 
 Governing Law. This Note shall be governed by and construed in
accordance with the laws of the State of New York.
