 ANNEX I 

The terms “Indenture” and “Company,” as used in this Annex I, have the respective meanings set forth in the Officers’
Certificate to which this Annex I is attached, and other capitalized terms used in this Annex I and not otherwise defined herein have the same definitions as in the Indenture. 

(1)    The series of Securities established hereby shall be known and designated as the 3.375% Notes due 2033 (the
“Offered Securities”). 
 (2)    The aggregate principal amount of the Offered Securities that may be
authenticated and delivered under the Indenture is initially limited to $450,000,000, except for the Offered Securities authenticated and delivered upon registration of, transfer of, or in exchange for, or in lieu of, other Offered Securities
pursuant to Sections 2.2A, 2.8, 2.9, 2.11, 8.5 or 12.3 of the Indenture or pursuant to the provisions appearing under the caption “Offer to Purchase Upon Change of Control Triggering Event” in the form of certificate evidencing the Offered
Securities attached hereto as Exhibit 1. However, the series of Securities of which the Offered Securities are a part may be re-opened from time to time by the Company for the issuance of additional Offered
Securities, without the consent of the Holders of the Offered Securities, so long as any such additional Offered Securities have the same form and terms (except that any such additional Offered Securities may be dated as of different dates and may
have different dates from which interest thereon shall begin to accrue), and carry the same right to receive accrued and unpaid interest, as the Offered Securities theretofore issued; provided, however, that, notwithstanding the foregoing, the
series of Securities of which the Offered Securities are a part may not be re-opened if the Company has effected satisfaction and discharge or defeasance with respect to the Offered Securities pursuant to
Section 10.1(A) or 10.1(B) of the Indenture; and provided, further, that no additional Offered Securities may be issued at a price that would cause such additional Offered Securities to have “original issue discount” within the
meaning of Section 1273 of the Internal Revenue Code of 1986, as amended. 
 (3)    The Offered Securities are to
be issuable only as Registered Securities without coupons. The Offered Securities shall be issued in book-entry form and represented by one or more Global Securities, the initial Depositary for such Global Securities shall be The Depository Trust
Company and the depositary arrangements shall be those employed by whomever shall be the Depositary with respect to such Global Securities from time to time. Notwithstanding the foregoing, certificated Offered Securities in definitive form may be
issued in exchange for Global Securities under the circumstances contemplated by clauses (c)(i), (ii) and (iii) of Section 2.2A of the Indenture. 

(4)    The Offered Securities authorized hereby shall be originally issued on March 9, 2022 (the “Closing
Date”) and shall be sold by the Company to the underwriters (the “Underwriters”) named in the Underwriting Agreement dated February 23, 2022 (the “Underwriting Agreement”) among the Company and BofA Securities, Inc.,
Goldman Sachs & Co. LLC, J.P. Morgan Securities LLC, Morgan Stanley & Co. LLC, and Wells Fargo Securities, LLC as representatives (the “Representatives”) of the several Underwriters (the form, terms, execution and
delivery of such Underwriting Agreement being hereby 

  
 Annex I-1 












 
authorized, ratified, confirmed and approved in all respects), at a price equal to 98.813% of the principal amount of the Offered Securities. The initial price to the public of the Offered
Securities originally issued on the Closing Date shall be 99.463% of the principal amount thereof plus accrued interest, if any, from March 9, 2022, and underwriting discounts and commissions shall be 0.650% of the principal amount of such
Offered Securities. 
 (5)    The final maturity date of the Offered Securities on which the principal thereof is due
and payable shall be March 9, 2033. 
 (6)    The principal of the Offered Securities will bear interest at the
rate set forth in the form of certificate evidencing the Offered Securities attached as Exhibit 1 hereto. Interest on the Offered Securities will accrue from the date, and will be payable on the dates and to the persons, provided in the form of
certificate evidencing the Offered Securities attached as Exhibit 1 hereto. Interest on the Offered Securities will be computed on the basis of a 360-day year of twelve
30- day months. No additional amounts of the nature referred to in subparagraph (15) of Section 2.3 of the Indenture shall be payable on the Offered Securities. 

(7)    The principal of and premium, if any, and interest on the Offered Securities shall be payable, the Offered
Securities may be surrendered for registration of transfer and exchange, and notices and demands to or upon the Company in respect of the Offered Securities or the Indenture may be served, at the agency of the Company maintained for such purposes
from time to time in the Borough of Manhattan, The City of New York, and the Company hereby appoints the Trustee as trustee, paying agent, transfer agent and registrar for the Offered Securities and designates the Corporate Trust Office of the
Trustee in the Borough of Manhattan, The City of New York, as the Company’s agency for the foregoing purposes; provided, however, that the Company, subject to the applicable provisions of the Indenture, may, with respect to the Offered
Securities, appoint another Person to be the registrar, transfer agent or paying agent, and appoint additional registrars, transfer agents and paying agents, with respect to the Offered Securities, so long as the Company shall at all times maintain
an agency for the foregoing purposes in the Borough of Manhattan, The City of New York for the Offered Securities. 

(8)    The Offered Securities may be redeemed by the Company, in whole at any time or from time to time in part, at the
option of the Company on any date upon not less than 10 nor more than 60 days notice given as provided in the Indenture, at a redemption price calculated as provided in the form of Offered Securities attached hereto as Exhibit 1, plus accrued and
unpaid interest on the principal amount of the Offered Securities being redeemed to the applicable redemption date; provided, however, that payments of interest on the Offered Securities that are due and payable on or prior to a date fixed for
redemption of the Offered Securities at the option of the Company will be payable to the Holders of the Offered Securities registered as such at the close of business on the relevant record dates according to their terms and the terms and provisions
of the Indenture. Any redemption of Offered Securities shall be made on the other terms and conditions set forth in the Indenture. The Offered Securities shall not be subject to a sinking fund or analogous provision. 

(9)    The Company will be required to offer to repurchase the Offered Securities, and to repurchase duly tendered Offered
Securities, upon the terms, and subject to the conditions, set forth under the caption “Offer to Purchase Upon Change of Control Triggering Event” in the form of certificate evidencing the Offered Securities attached as Exhibit 1 hereto.


  
 Annex I-2

Securities shall be payable in such coin or currency of the United States of America as of the time of payment shall be legal tender for the payment of public and private debts. 

(11)    The Offered Securities shall be issued in denominations of $2,000 and integral multiples of $1,000 in excess
thereof. 
 (12)    To the extent that any provision of the Indenture or the Offered Securities provides for the payment
of interest on overdue principal of, or premium, if any, or interest on, the Offered Securities, then, to the extent permitted by applicable law, interest on such overdue principal, premium, if any, and interest shall accrue at the rate of interest
borne by the Offered Securities, and, anything in the Indenture to the contrary notwithstanding, in the case of any requirement in the Indenture that the Company pay (or that the Trustee distribute) interest on overdue principal of, or premium, if
any, or interest on, the Offered Securities, such payment or distribution shall only be required to the extent it is permitted by applicable law. 

(13)    As used in the Indenture with respect to the Offered Securities and in the certificates evidencing the Offered
Securities, all references to “premium” on the Offered Securities shall mean any amounts (other than accrued interest) payable upon the redemption of any Offered Security, or the repurchase of any Offered Security pursuant to the
provisions set forth under the caption “Offer to Purchase Upon Change of Control Triggering Event” in the form of certificate evidencing the Offered Securities attached hereto as Exhibit 1, in excess of 100% of the principal amount of such
Offered Security.

the Offered Securities and the Offered Securities shall not be entitled to the benefits of such Section 3.9.

	 	(a)	 the phrase “due or to become due to such date of maturity” appearing in the 28th and 29th lines of Section 10.1(A) of the Indenture shall be deleted and replaced with the phrase “due or to become due on or prior to
such date of maturity or redemption, as the case may be,” 


  

	 	(b)	 the Company shall not act as its own paying agent for purposes of Section 10.2 of the Indenture or for
purposes of the provisions set forth under the caption “Offer to Purchase Upon Change of Control Triggering Event” in the form of certificate evidencing the Offered Securities attached hereto as Exhibit 1; 



 

	 	(c)	 all references in the Indenture to the “Secretary” and any “Assistant Secretary” of the

 Annex I-3 













	 	(d)	 the phrase “acquires by sale or conveyance substantially all the assets” appearing in clause
(i) of Section 9.1 of the Indenture shall be deleted and replaced with the phrase “acquires by sale or conveyance all or substantially all the assets”. 



(16)    The certificates evidencing the Offered Securities shall be in substantially the form attached hereto as Exhibit
1, it being understood that the certificate evidencing any Offered Security may be modified so that the signatures and/or trustee’s certificate of authentication appear on the same page as the principal amount of such Offered Security and that
the format (but not the substance) of any such certificate may also be changed in such manner as any officer the Company may approve, such approval to be conclusively evidenced by the authentication of any such certificate by the Trustee. 

(17)    The Offered Securities shall have such additional terms and provisions as are set forth in the form of certificate
evidencing the Offered Securities attached hereto as Exhibit 1, which terms and provisions are hereby incorporated by reference in and made a part of this Annex I and the Indenture as if set forth in full herein and therein.

is a date to which interest has been paid or duly provided for, in which case from the date of this Note, or unless no interest has been paid or duly provided for on this Note, in which case from
March 9, 2022, until payment of said principal sum has been made or duly provided for; provided that, if this Note is not a Global Security, payment of interest will be made against presentation of this Note at the office or agency of the

provided, that if the Issuer shall default in the payment of interest due on such Interest Payment Date, then this Note shall bear interest from the next preceding Interest Payment Date to which interest has been paid or duly provided for or,
if no interest has been paid or duly provided for on this Note, from March 9, 2022; and provided, further, that, notwithstanding the foregoing provisions of this sentence, if no interest has been paid or duly provided for on this

 This Note is one of a duly authorized issue of Securities of the Issuer issued under and
pursuant to an Indenture dated as of April 1, 1986 (the “Original Indenture”), as amended and supplemented by a First Supplemental Indenture thereto dated as of February 15, 1991 (the “First Supplemental Indenture”), a
Second Supplemental Indenture thereto dated as of February 1, 1993 (the “Second Supplemental Indenture”), a Third Supplemental Indenture thereto dated as of October 22, 2001 (the “Third Supplemental Indenture”), a
Fourth Supplemental Indenture thereto dated as of March 12, 2002 (the “Fourth Supplemental Indenture”) and a Fifth Supplemental Indenture thereto dated as of March 30, 2020 (the “Fifth Supplemental Indenture”; the
Original Indenture, as amended and supplemented by the First Supplemental Indenture, the Second Supplemental Indenture, the Third Supplemental Indenture, the Fourth Supplemental Indenture, the Fifth Supplemental Indenture and any other indentures
supplemental thereto, is hereinafter called the “Indenture”), each between the Issuer and The Bank of New York Mellon Trust Company, N.A. (formerly known as The Bank of New York Trust Company, N.A.), as successor trustee (herein called the
“Trustee”, which term includes any successor trustee under the Indenture) to JPMorgan Chase Bank (formerly known as The Chase Manhattan Bank and Chemical Bank), to which Indenture and all indentures supplemental thereto reference is hereby
made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Issuer and the Holders of the Securities. The Securities may be issued in one or more series, which different series may
be issued in various aggregate principal amounts, may mature at different times, may bear interest (if any) at different rates, may be subject to different redemption provisions (if any), may be subject to different sinking, purchase or analogous
funds (if any) and may otherwise vary as in the Indenture provided. This Note is one of the series of Securities designated on the face hereof (the “Notes”). 

  
 Exhibit 1-2 












 Prior to December 9, 2032 (three months prior to their maturity date) (the “Par
Call Date”), the Issuer may redeem the Notes at its option, in whole or in part, at any time and from time to time, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater
of: 
 (1) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the
redemption date (assuming the Notes matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury
Rate plus 25 basis points less (b) interest accrued to the date of redemption, and 
 (2) 100% of the principal amount of the Notes to
be redeemed, 
 plus, in either case, accrued and unpaid interest thereon to the redemption date. 

On or after the Par Call Date, the Issuer may redeem 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 the redemption date. 
 For
purposes of the foregoing provisions related to optional redemption, the following definitions are applicable: 
 “Business Day”
means each Monday, Tuesday, Wednesday, Thursday and Friday that is not a day on which banking institutions in The City of New York are authorized or obligated by law, regulation or executive order to close. 

“Treasury Rate” means, with respect to any redemption date, the yield determined by the Issuer in accordance with the following two
paragraphs. 
 The Treasury Rate shall be determined by the Issuer 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). In determining the Treasury Rate, the Issuer 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 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 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


  
 Exhibit 1-3 












 
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 or any successor designation or publication is no longer published, the Issuer
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 Par Call Date, as applicable. If there is no United States Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities with a maturity date
equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, the Issuer shall select the United States Treasury security with a maturity date preceding the Par
Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Issuer 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
Issuer’s actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error. 

Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with the depositary’s
procedures) at least 10 days but not more than 60 days before the redemption date to each holder of Notes to be redeemed. 
 In the case of
a partial redemption, selection of the Notes for redemption will be made pro rata, by lot or by such other method as is consistent with policies and procedures of the Trustee; and for so long as the Notes are held by DTC (or another depositary), the
selection of the Notes for redemption shall be done in accordance with the policies and procedures of the depositary. 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. 
 Unless the Issuer 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. 

  
 Exhibit 1-4 












 Notwithstanding the provisions of Section 12.2 of the Indenture, any notice of
redemption of the Notes need not set forth the redemption price but only the manner of calculation thereof. The Issuer will notify the Trustee of the redemption price promptly after the calculation thereof. The Trustee shall have no responsibility
for such calculation. 
 In case an Event of Default (as defined in the Indenture) with respect to the Notes shall have occurred and be
continuing, the principal hereof and accrued and unpaid interest hereon may be declared, and upon such declaration shall become, due and payable, in the manner, with the effect and subject to the conditions provided in the Indenture. 

The Indenture contains provisions permitting the Issuer and the Trustee, with the consent of the Holders of not less than a majority in
aggregate principal amount of the Securities at the time Outstanding of all series to be affected (voting as one class), evidenced as in the Indenture provided, to execute supplemental indentures adding any provisions to or changing in any manner or
eliminating any of the provisions of the Indenture or of any supplemental indenture or modifying in any manner the rights of the Holders of the Securities of each such series; provided, that no such supplemental indenture shall, among other
things, (i) extend the final maturity of any Security, or reduce the principal amount thereof or reduce the rate or extend the time of payment of any interest thereon, or reduce any amount payable on the redemption thereof, or make the
principal thereof or the interest thereon payable in any coin or currency other than that provided in the Securities or in accordance with the terms thereof, or impair or affect the rights of any Holder to institute suit for the payment thereof,
without the consent of the Holder of each Security so affected, or (ii) reduce the aforesaid percentage of Securities the Holders of which are required to consent to any such supplemental indenture without the consent of the Holder of each
Security so affected. It is also provided in the Indenture that, with respect to certain defaults or Events of Default, prior to any declaration accelerating the maturity of the Securities of any series, the Holders of a majority in aggregate
principal amount of the Outstanding Securities of such series (or, in the case of certain defaults or Events of Default, all or certain series of the Securities) may on behalf of the Holders of all the Securities of such series (or all or certain
series of the Securities, as the case may be) waive any such past default or Event of Default and its consequences. The preceding sentence shall not, however, apply to a default or Event of Default in respect of the payment of the principal of or
premium, if any, or interest on any of the Securities or a default or Event of Default in respect of a covenant or provision of the Indenture which cannot be modified or amended without the consent of the Holder of each Security affected. Any such
consent or waiver by the Holder of this Note (unless revoked as provided in the Indenture) shall be conclusive and binding upon such Holder and upon all future Holders and owners of this Note and any Notes which may be issued in exchange or
substitution herefor or on registration of transfer hereof, irrespective of whether or not any notation thereof is made upon this Note or such other Notes. 

No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Issuer,
which is absolute and unconditional, to pay the principal of and premium, if any, and interest on this Note in the manner, at the respective times, at the rate and in the coin or currency herein prescribed. 

The Notes are issuable in registered form without coupons in denominations of $2,000 and any integral multiple of $1,000 in excess thereof.
Notes may be exchanged for a like 

  
 Exhibit 1-5 












 
aggregate principal amount of Notes of other authorized denominations upon surrender of the Notes to be exchanged at the agency of the Issuer maintained for that purpose in the Borough of
Manhattan, The City of New York in the manner and subject to the limitations provided in the Indenture, without charge except for any tax or other governmental charge that may be imposed in connection therewith. 

The Notes are not subject to any sinking fund. 

Upon due presentment for registration of transfer of this Note at the agency of the Issuer maintained for that purpose, a new Note or Notes of
authorized denominations for an equal aggregate principal amount will be issued to the transferee in exchange therefor, subject to the limitations provided in the Indenture, without charge except for any tax or other governmental charge that may be
imposed in connection therewith. 
 The Issuer, the Trustee and any authorized agent of the Issuer or the Trustee may deem and treat the
registered Holder hereof as the absolute owner of this Note (whether or not this Note shall be overdue and notwithstanding any notation of ownership or other writing hereon), for the purpose of receiving payment of, or on account of, the principal
hereof and premium, if any, and, subject to the provisions of the first paragraph hereof, interest hereon and for all other purposes, and neither the Issuer nor the Trustee nor any authorized agent of the Issuer or the Trustee shall be affected by
any notice to the contrary. 
 No recourse under or upon any obligation, covenant or agreement of the Issuer in the Indenture or in any
Note, or because of any indebtedness represented thereby, shall be had against any incorporator, stockholder, officer or director, as such, of the Issuer or of any successor entity, either directly or through the Issuer or any successor entity,
under any rule of law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise, all such liability being expressly waived and released by the acceptance hereof and as part of
the consideration for the issue hereof. 
 This Note shall be governed by and construed in accordance with the laws of the State of New
York, except as may otherwise be required by mandatory provisions of law. 
 Terms used in this Note which are defined in the Indenture
shall have the respective meanings assigned thereto in the Indenture, except that the terms “Business Day” and “business day,” as used in this Note, shall have the meanings set forth herein. 

The Indenture contains provisions whereby the Issuer may be discharged from its obligations with respect to the Notes, subject to exceptions,
if the Issuer deposits with the Trustee cash or U.S. Government Obligations in the amount and in the manner, and satisfies certain other conditions, as in the Indenture provided. 

This Note shall not be valid or obligatory for any purpose until the certificate of authentication hereon shall have been signed by or on
behalf of the Trustee under the Indenture by manual or electronic signature of an authorized signatory of the Trustee. 

  
 Exhibit 1-6 












 Offer to Purchase Upon Change of Control Triggering Event 

If a Change of Control Triggering Event occurs with respect to the Notes, the Issuer will make an offer (the “Change of Control
Offer”) to each Holder of Notes to repurchase (at such Holder’s option) all or any part (in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof, provided that any portion of a Note not repurchased must be in a
principal amount of $2,000 or an integral multiple of $1,000 in excess thereof) of such Holder’s Notes on the terms described below. In the Change of Control Offer, the Issuer will offer payment in cash equal to 101% of the principal amount of
the Notes to be repurchased, plus accrued and unpaid interest, if any, on such Notes (or portions thereof) to be repurchased to, but excluding, the date of repurchase (the “Change of Control Payment”); provided that, notwithstanding the
foregoing, payments of interest on the Notes that are due and payable on any dates falling on or prior to such a date of repurchase will be payable to the Holders of those Notes registered as such at the close of business on the relevant record
dates in accordance with their terms and the terms of the Indenture. Within 30 days following any Change of Control Triggering Event with respect to the Notes, the Issuer will mail (or otherwise transmit in accordance with applicable procedures of
DTC) (or cause to be mailed (or otherwise transmitted in accordance with applicable procedures of DTC)) a notice (the “Change of Control Purchase Notice”) to all Holders of Notes (with a copy to the Trustee) describing the transaction or
transactions constituting the Change of Control Triggering Event and offering to repurchase the Notes on the date specified in such notice, which date will be a business day no earlier than 10 days and no later than 60 days after the date such
notice is mailed (or otherwise transmitted in accordance with applicable procedures of DTC) (the “Change of Control Payment Date”). 

Holders electing to have a Note or portion thereof repurchased pursuant to a Change of Control Offer will be required to surrender the Note
(which, in the case of Notes in book-entry form, may be by book-entry transfer) to the Trustee (or to such other agent as may be appointed by the Issuer for such purpose) at the address specified in the applicable Change of Control Purchase Notice
prior to the close of business on the business day immediately preceding the applicable Change of Control Payment Date and to comply with other procedures set forth in such Change of Control Purchase Notice. As used in the preceding sentence and in
the last sentence of the preceding paragraph, the term “business day” means any day, other than a Saturday or Sunday, that is neither a legal holiday nor a day on which commercial banks are authorized or required by law, regulation or
executive order to close in The City of New York. 
 On any Change of Control Payment Date, the Issuer will, 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 Trustee (if the Trustee is acting as paying agent for the Notes) or any other duly appointed
paying agent for the Notes an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes properly tendered; and 


  

	 	(3)	 deliver the repurchased Notes or cause the repurchased Notes to be delivered to the Trustee for cancellation,
accompanied by an Officers’ Certificate stating 



  
 Exhibit 1-7 













	 	
the aggregate principal amount of repurchased Notes and that all conditions precedent provided for in the Notes and the Indenture relating to such Change of Control Offer and the repurchase of
Notes by the Issuer pursuant thereto have been complied with. 

 Interest on Notes and portions of Notes duly tendered for repurchase pursuant
to a Change of Control Offer will cease to accrue on and after the applicable Change of Control Payment Date, unless the Issuer shall have failed to accept such Notes and such portions of Notes for payment, failed to deposit the total Change of
Control Payment in respect thereof or failed to deliver the Officers’ Certificate, all as required by, and in accordance with, the immediately preceding sentence. 

The Issuer will agree to promptly pay, or will cause the Trustee (if the Trustee is acting as paying agent for the Notes) or another duly
appointed paying agent for the Notes to promptly pay (by application of funds deposited by the Issuer), to each Holder of Notes (or portions thereof) duly tendered and accepted for payment by the Issuer pursuant to a Change of Control Offer for the
Notes, the Change of Control Payment for such Notes, and the Issuer will cause the Trustee to promptly authenticate and mail (or deliver by book entry transfer, as applicable) to each such Holder a new Note equal in principal amount to the
unpurchased portion, if any, of the Notes surrendered by such Holder; provided that each such new Note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. The Issuer shall, or shall cause the Trustee to,
promptly mail (or cause to be delivered by book entry transfer, as applicable) to the Holders thereof any Notes not so accepted for payment by the Issuer. 

The Issuer will comply with the requirements of Rule 14e-1 under the Exchange Act and any other
securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of 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 the Change of Control Offer provisions of the Notes, the Issuer shall comply with those securities laws and regulations and shall not be deemed to have breached its obligations under the Change of Control
Offer provisions of the Notes by virtue of such conflict. 
 The Issuer will 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 time and otherwise in compliance with the requirements for an offer made by the Issuer and the third party purchases all Notes properly
tendered under its offer and delivers the repurchased Notes or causes the repurchased Notes to be delivered to the Trustee for cancellation on the applicable Change of Control Payment Date. In addition, the Issuer will not repurchase any Notes
pursuant to a Change of Control Offer if there has occurred and is continuing on the applicable Change of Control Payment Date an Event of Default under the Indenture (other than an Event of Default resulting from the Issuer’s failure to comply
with any of the provisions of the Notes or the Indenture relating to such Change of Control Offer or the repurchase of Notes pursuant thereto, including, without limitation, any default in payment of the Change of Control Payment), including Events
of Default arising with respect to other series of Securities outstanding under the Indenture. 

  
 Exhibit 1-8 












 The foregoing Change of Control provisions of the Notes shall cease to be applicable (and
any failure of the Issuer to comply therewith shall not constitute an Event of Default) if (i) the Indenture shall have ceased to be of further effect with respect to the Notes pursuant to Section 10.1(A) of the Indenture (as used in this
paragraph, “satisfaction and discharge”), or (ii) the Issuer shall be deemed to have paid and discharged the entire indebtedness on all of the Notes pursuant to Section 10.1(B) of the Indenture (as used in this paragraph,
“defeasance”) (it being understood that, in addition to the other conditions to defeasance set forth in the Indenture, any such defeasance shall not be effective until the 121st day after the date of deposit referred to in subparagraph
(a) of Section 10.1(B) of the Indenture), and, in the case of both clause (i) and (ii) of this sentence, the Issuer shall have satisfied the conditions set forth in the Indenture to such satisfaction and discharge or such defeasance,
as the case may be, and (without limitation to the foregoing) shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel (each of which comply with Section 11.5 of the Indenture), each to the effect that all
conditions precedent to such satisfaction and discharge or defeasance, as the case may be, provided for in the Indenture have been complied with. 

For purposes of the provisions set forth under this caption “Offer to Purchase Upon Change of Control Triggering Event,” the
following terms have the respective meanings specified below: 
 “Capital Stock” means, with respect to any Person, any and all
shares, interests, participations or other equivalents (however designated) in the equity of such Person (including, without limitation, (i) with respect to a corporation, common stock, preferred stock and any other capital stock,
(ii) with respect to a partnership, partnership interests (whether general or limited), and (iii) with respect to a limited liability company, limited liability company interests). 

“Change of Control” means the occurrence of any of the following: (a) the consummation of any transaction (including, without
limitation, any merger or consolidation) resulting in any “person” (as that term is used in Section 13(d)(3) of the Exchange Act) (other than the Issuer or any of its subsidiaries) becoming the “beneficial owner” (as defined
in Rules 13d-3 and 13d-5 under the Exchange Act), directly or indirectly, of more than 50% of the Issuer’s outstanding Voting Stock or other Voting Stock into which
the Issuer’s Voting Stock is reclassified, consolidated, exchanged or changed, measured by voting power rather than number of shares or (b) the direct or indirect sale, transfer, conveyance or other disposition (other than by way of merger
or consolidation), in one transaction or a series of related transactions, of all or substantially all of the properties or assets of the Issuer and its subsidiaries, taken as a whole, to one or more Persons (other than the Issuer or any of its
subsidiaries). Notwithstanding the foregoing, a transaction will not be deemed to be a Change of Control if (1) the Issuer becomes a direct or indirect wholly-owned subsidiary of a holding company and (2)(y) the direct or indirect holders of
the Voting Stock of such holding company immediately following that transaction are substantially the same as the holders of the Issuer’s Voting Stock immediately prior to that transaction or (z) immediately following that transaction no
“person” (as that term is used in Section 13(d)(3) of the Exchange Act), other than a holding company satisfying the requirements of this sentence, is the “beneficial owner” (as defined in Rules 13d-3 and 13d-5 under the Exchange Act), directly or indirectly, of more than 50% of the outstanding Voting Stock of such holding company, measured by voting power rather than
number of shares. As used in this paragraph, the term “subsidiary” means, with respect to any Person (the “Parent”), any other 

  
 Exhibit 1-9 












 
Person at least a majority of whose outstanding Voting Stock, measured by voting power rather than number of shares, is owned, directly or indirectly, at the date of determination by the Parent
and/or one or more other subsidiaries of the Parent. 
 “Change of Control Triggering Event” means the occurrence of both a Change
of Control and a Rating Event. 
 “Exchange Act” means the Securities Exchange Act of 1934, as amended, or any successor thereto.

 “Investment Grade Rating” means a rating equal to or higher than Baa3 (or the equivalent) by Moody’s and BBB- (or the equivalent) by S&P, and the equivalent investment grade credit rating from any replacement Rating Agency or Rating Agencies selected by the Issuer. 

“Moody’s” means Moody’s Investors Service, Inc. 

“Rating Agencies” means (a) each of Moody’s and S&P; and (b) if either of Moody’s or S&P ceases to rate
the Notes or fails to make a rating of the Notes publicly available for reasons outside of the Issuer’s control, a “nationally recognized statistical rating organization” (within the meaning of Rule
15c3-1(c)(2)(vi)(F) under the Exchange Act) selected by the Issuer (as certified by a Board Resolution delivered to the Trustee) as a replacement for Moody’s or S&P, or both of them, as the case may
be. 
 “Rating Event” means the rating on the Notes is lowered by each of the Rating Agencies and the Notes are rated below an
Investment Grade Rating by each of the Rating Agencies on any day within the 60-day period (which 60-day period shall be extended so long as the rating of the Notes is
under publicly announced consideration for a possible downgrade by either of the Rating Agencies) after the earlier of (a) the occurrence of a Change of Control and (b) public notice of the occurrence of a Change of Control or the
Issuer’s intention to effect a Change of Control; provided, however, that a Rating Event otherwise arising by virtue of a particular reduction in rating will not be deemed to have occurred in respect of a particular Change of Control (and thus
will not be deemed a Rating Event for purposes of the definition of “Change of Control Triggering Event”) if each Rating Agency making the reduction in rating to which this definition would otherwise apply does not announce or publicly
confirm or inform the Issuer in writing that the reduction was the result, in whole or in part, of any event or circumstance comprised of or arising as a result of, or in respect of, the applicable Change of Control (whether or not the applicable
Change of Control has occurred at the time of the Rating Event). The Trustee shall not be responsible for monitoring the ratings of the Notes nor shall it be charged with knowledge of such ratings. 

“S&P” means S&P Global Ratings, a division of S&P Global Inc., and its successors. 

“Voting Stock” means, with respect to any specified “person” (as that term is used in Section 13(d)(3) of the
Exchange Act) as of any date, any Capital Stock of such person that is at the time entitled to vote generally in the election of the board of directors of such person or, if such person is not a corporation, any governing body thereof performing a
similar function. 

  
 Exhibit 1-10 












 As used under this caption “Offer to Purchase Upon Change of Control Triggering
Event,” all references to sections of the Exchange Act and to rules and regulations under the Exchange Act shall include any successor provisions thereto. 

For purposes of clarity, the Issuer confirms that (1) the provisions set forth under this caption “Offer to Purchase Upon Change of
Control Triggering Event” constitute covenants of the Issuer under the Indenture in respect of, and solely for the benefit of the Holders of, the Notes, (2) for purposes of Section 5.1(d), Section 5.10, Section 8.2 and any
other applicable provisions of the Indenture, the Notes shall be deemed to be the only series of Securities affected by such covenants or by any default in the performance, or breach, of any such covenants or any default or Event of Default
resulting therefrom or by any change therein or amendment thereto or waiver thereof and, without limitation to the foregoing, any such default or Event of Default shall be deemed to be a default or Event of Default, as the case may be, only with
respect to the Notes, (3) such covenants shall constitute a “right of repayment at the option of the Securityholder” for purposes of Section 8.2 of the Indenture and, without limitation to the foregoing, no supplemental indenture
entered into pursuant to Article Eight of the Indenture shall reduce the amount payable in respect of, or extend the time for payment of, any Notes pursuant to such covenants without the consent of the Holder of each Note so affected and
(4) any failure by the Issuer to pay all or any part of the Change of Control Payment as and when required pursuant to such covenants shall constitute an Event of Default with respect to the Notes under Section 5.1(b) of the Indenture.

 ANNEX II 

The terms “Indenture” and “Company,” as used in this Annex II, have the respective meanings set forth in the
Officers’ Certificate to which this Annex II is attached, and other capitalized terms used in this Annex II and not otherwise defined herein have the same definitions as in the Indenture. 

(1)    The series of Securities established hereby shall be known and designated as the 4.000% Notes due 2052 (the
“Offered Securities”). 
 (2)    The aggregate principal amount of the Offered Securities that may be
authenticated and delivered under the Indenture is initially limited to $450,000,000, except for the Offered Securities authenticated and delivered upon registration of, transfer of, or in exchange for, or in lieu of, other Offered Securities
pursuant to Sections 2.2A, 2.8, 2.9, 2.11, 8.5 or 12.3 of the Indenture or pursuant to the provisions appearing under the caption “Offer to Purchase Upon Change of Control Triggering Event” in the form of certificate evidencing the Offered
Securities attached hereto as Exhibit 1. However, the series of Securities of which the Offered Securities are a part may be re-opened from time to time by the Company for the issuance of additional Offered
Securities, without the consent of the Holders of the Offered Securities, so long as any such additional Offered Securities have the same form and terms (except that any such additional Offered Securities may be dated as of different dates and may
have different dates from which interest thereon shall begin to accrue), and carry the same right to receive accrued and unpaid interest, as the Offered Securities theretofore issued; provided, however, that, notwithstanding the foregoing, the
series of Securities of which the Offered Securities are a part may not be re-opened if the Company has effected satisfaction and discharge or defeasance with respect to the Offered Securities pursuant to
Section 10.1(A) or 10.1(B) of the Indenture; and provided, further, that no additional Offered Securities may be issued at a price that would cause such additional Offered Securities to have “original issue discount” within the
meaning of Section 1273 of the Internal Revenue Code of 1986, as amended. 
 (3)    The Offered Securities are to
be issuable only as Registered Securities without coupons. The Offered Securities shall be issued in book-entry form and represented by one or more Global Securities, the initial Depositary for such Global Securities shall be The Depository Trust
Company and the depositary arrangements shall be those employed by whomever shall be the Depositary with respect to such Global Securities from time to time. Notwithstanding the foregoing, certificated Offered Securities in definitive form may be
issued in exchange for Global Securities under the circumstances contemplated by clauses (c)(i), (ii) and (iii) of Section 2.2A of the Indenture. 

(4)    The Offered Securities authorized hereby shall be originally issued on March 9, 2022 (the “Closing
Date”) and shall be sold by the Company to the underwriters (the “Underwriters”) named in the Underwriting Agreement dated February 23, 2022 (the “Underwriting Agreement”) among the Company and BofA Securities, Inc.,
Goldman Sachs & Co. LLC, J.P. Morgan Securities LLC, Morgan Stanley & Co. LLC, and Wells Fargo Securities, LLC as representatives (the “Representatives”) of the several Underwriters (the form, terms, execution and
delivery of such Underwriting Agreement being hereby 

  
 Annex II-1 












 
authorized, ratified, confirmed and approved in all respects), at a price equal to 97.391% of the principal amount of the Offered Securities. The initial price to the public of the Offered
Securities originally issued on the Closing Date shall be 98.266% of the principal amount thereof plus accrued interest, if any, from March 9, 2022, and underwriting discounts and commissions shall be 0.875% of the principal amount of such
Offered Securities. 
 (5)    The final maturity date of the Offered Securities on which the principal thereof is due
and payable shall be March 9, 2052. 
 (6)    The principal of the Offered Securities will bear interest at the
rate set forth in the form of certificate evidencing the Offered Securities attached as Exhibit 1 hereto. Interest on the Offered Securities will accrue from the date, and will be payable on the dates and to the persons, provided in the form of
certificate evidencing the Offered Securities attached as Exhibit 1 hereto. Interest on the Offered Securities will be computed on the basis of a 360-day year of twelve
30- day months. No additional amounts of the nature referred to in subparagraph (15) of Section 2.3 of the Indenture shall be payable on the Offered Securities. 

(7)    The principal of and premium, if any, and interest on the Offered Securities shall be payable, the Offered
Securities may be surrendered for registration of transfer and exchange, and notices and demands to or upon the Company in respect of the Offered Securities or the Indenture may be served, at the agency of the Company maintained for such purposes
from time to time in the Borough of Manhattan, The City of New York, and the Company hereby appoints the Trustee as trustee, paying agent, transfer agent and registrar for the Offered Securities and designates the Corporate Trust Office of the
Trustee in the Borough of Manhattan, The City of New York, as the Company’s agency for the foregoing purposes; provided, however, that the Company, subject to the applicable provisions of the Indenture, may, with respect to the Offered
Securities, appoint another Person to be the registrar, transfer agent or paying agent, and appoint additional registrars, transfer agents and paying agents, with respect to the Offered Securities, so long as the Company shall at all times maintain
an agency for the foregoing purposes in the Borough of Manhattan, The City of New York for the Offered Securities. 

(8)    The Offered Securities may be redeemed by the Company, in whole at any time or from time to time in part, at the
option of the Company on any date upon not less than 10 nor more than 60 days notice given as provided in the Indenture, at a redemption price calculated as provided in the form of Offered Securities attached hereto as Exhibit 1, plus accrued and
unpaid interest on the principal amount of the Offered Securities being redeemed to the applicable redemption date; provided, however, that payments of interest on the Offered Securities that are due and payable on or prior to a date fixed for
redemption of the Offered Securities at the option of the Company will be payable to the Holders of the Offered Securities registered as such at the close of business on the relevant record dates according to their terms and the terms and provisions
of the Indenture. Any redemption of Offered Securities shall be made on the other terms and conditions set forth in the Indenture. The Offered Securities shall not be subject to a sinking fund or analogous provision. 

(9)    The Company will be required to offer to repurchase the Offered Securities, and to repurchase duly tendered Offered
Securities, upon the terms, and subject to the conditions, set forth under the caption “Offer to Purchase Upon Change of Control Triggering Event” in the form of certificate evidencing the Offered Securities attached as Exhibit 1 hereto.


  
 Annex II-2 












 (10)    The principal of, premium, if any, and interest on the Offered
Securities shall be payable in such coin or currency of the United States of America as of the time of payment shall be legal tender for the payment of public and private debts. 

(11)    The Offered Securities shall be issued in denominations of $2,000 and integral multiples of $1,000 in excess
thereof. 
 (12)    To the extent that any provision of the Indenture or the Offered Securities provides for the payment
of interest on overdue principal of, or premium, if any, or interest on, the Offered Securities, then, to the extent permitted by applicable law, interest on such overdue principal, premium, if any, and interest shall accrue at the rate of interest
borne by the Offered Securities, and, anything in the Indenture to the contrary notwithstanding, in the case of any requirement in the Indenture that the Company pay (or that the Trustee distribute) interest on overdue principal of, or premium, if
any, or interest on, the Offered Securities, such payment or distribution shall only be required to the extent it is permitted by applicable law. 

(13)    As used in the Indenture with respect to the Offered Securities and in the certificates evidencing the Offered
Securities, all references to “premium” on the Offered Securities shall mean any amounts (other than accrued interest) payable upon the redemption of any Offered Security, or the repurchase of any Offered Security pursuant to the
provisions set forth under the caption “Offer to Purchase Upon Change of Control Triggering Event” in the form of certificate evidencing the Offered Securities attached hereto as Exhibit 1, in excess of 100% of the principal amount of such
Offered Security. 
 (14)    The provisions of Section 3.9 of the Indenture shall not be applicable with respect to
the Offered Securities and the Offered Securities shall not be entitled to the benefits of such Section 3.9. 

(15)    The following additional terms shall be applicable with respect to the Offered Securities: 

 

	 	(a)	 the phrase “due or to become due to such date of maturity” appearing in the 28th and 29th lines of Section 10.1(A) of the Indenture shall be deleted and replaced with the phrase “due or to become due on or prior to
such date of maturity or redemption, as the case may be,” 


  

	 	(b)	 the Company shall not act as its own paying agent for purposes of Section 10.2 of the Indenture or for
purposes of the provisions set forth under the caption “Offer to Purchase Upon Change of Control Triggering Event” in the form of certificate evidencing the Offered Securities attached hereto as Exhibit 1; 



 

	 	(c)	 all references in the Indenture to the “Secretary” and any “Assistant Secretary” of the
Company shall be deemed to include a reference to the Corporate Secretary and any Assistant Corporate Secretary, respectively, of the Company; and 



  
 Annex II-3 













	 	(d)	 the phrase “acquires by sale or conveyance substantially all the assets” appearing in clause
(i) of Section 9.1 of the Indenture shall be deleted and replaced with the phrase “acquires by sale or conveyance all or substantially all the assets”. 



(16)    The certificates evidencing the Offered Securities shall be in substantially the form attached hereto as Exhibit

4.000% Note due 2052 

WEYERHAEUSER COMPANY, a Washington corporation (the “Issuer,” which term includes any successor thereto under the Indenture referred
to below), for value received, hereby promises to pay to · [For inclusion in Global Securities—Cede &
Co.], or registered assigns, at the office or agency of the Issuer maintained for such purpose in the Borough of Manhattan, The City of New York, the principal sum of
· Dollars ($·,000,000) on March 9, 2052, in such coin or currency of the United States of America as at the time of payment shall be legal tender for the payment of public and private debts, and to pay interest,

 Exhibit 1-2 












 
the date of this Note to which interest has been paid or duly provided for, unless the date hereof is a date to which interest has been paid or duly provided for, in which case from the date of
this Note, or unless no interest has been paid or duly provided for on this Note, in which case from March 9, 2022, until payment of said principal sum has been made or duly provided for; provided that, if this Note is not a Global Security,
payment of interest will be made against presentation of this Note at the office or agency of the Issuer maintained for such purpose in the Borough of Manhattan, The City of New York (and the offices or agencies of the Issuer maintained for such
purpose in any such other locations, if any, as the Issuer may from time to time elect) or, at the option of the Issuer, by check mailed to the address of the Person entitled thereto as such address shall appear on the Security register; and
provided, further, that if this Note is a Global Security registered in the name of a Depositary or its nominee, payment of interest shall be made to the Depositary or its nominee, as the case may be, in accordance with the Depositary’s
procedures as in effect from time to time. Notwithstanding the foregoing, if the date hereof is after February 25 or August 25, whether or not a Business Day (each, a “Regular Record Date”), as the case may be, and before the
following Interest Payment Date, this Note shall bear interest from such Interest Payment Date; provided, that if the Issuer shall default in the payment of interest due on such Interest Payment Date, then this Note shall bear interest from
the next preceding Interest Payment Date to which interest has been paid or duly provided for or, if no interest has been paid or duly provided for on this Note, from March 9, 2022; and provided, further, that, notwithstanding the
foregoing provisions of this sentence, if no interest has been paid or duly provided for on this Note, then this Note shall bear interest from March 9, 2022. The interest so payable on any Interest Payment Date will, subject to certain
exceptions provided in the Indenture referred to below, be paid to the Person in whose name this Note is registered at the close of business on the Regular Record Date next preceding such Interest Payment Date. Interest on this Note shall be
calculated on the basis of a 360-day year consisting of twelve 30-day months. 

This Note is one of a duly authorized issue of Securities of the Issuer issued under and pursuant to an Indenture dated as of April 1,
1986 (the “Original Indenture”), as amended and supplemented by a First Supplemental Indenture thereto dated as of February 15, 1991 (the “First Supplemental Indenture”), a Second Supplemental Indenture thereto dated as of
February 1, 1993 (the “Second Supplemental Indenture”), a Third Supplemental Indenture thereto dated as of October 22, 2001 (the “Third Supplemental Indenture”), a Fourth Supplemental Indenture thereto dated as of
March 12, 2002 (the “Fourth Supplemental Indenture”) and a Fifth Supplemental Indenture thereto dated as of March 30, 2020 (the “Fifth Supplemental Indenture”; the Original Indenture, as amended and supplemented by the
First Supplemental Indenture, the Second Supplemental Indenture, the Third Supplemental Indenture, the Fourth Supplemental Indenture, the Fifth Supplemental Indenture and any other indentures supplemental thereto, is hereinafter called the
“Indenture”), each between the Issuer and The Bank of New York Mellon Trust Company, N.A. (formerly known as The Bank of New York Trust Company, N.A.), as successor trustee (herein called the “Trustee”, which term includes any
successor trustee under the Indenture) to JPMorgan Chase Bank (formerly known as The Chase Manhattan Bank and Chemical Bank), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights,
limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Issuer and the Holders of the Securities. The Securities may be issued in one or more series, which different series may be issued in various aggregate
principal 

  
 Exhibit 1-3 












 
amounts, may mature at different times, may bear interest (if any) at different rates, may be subject to different redemption provisions (if any), may be subject to different sinking, purchase or
analogous funds (if any) and may otherwise vary as in the Indenture provided. This Note is one of the series of Securities designated on the face hereof (the “Notes”). 

Prior to September 9, 2051 (six months prior to their maturity date) (the “Par Call Date”), the Issuer may redeem the Notes at
its option, in whole or in part, at any time and from time to time, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of: 

(1) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date
(assuming the Notes matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 30 basis
points less (b) interest accrued to the date of redemption, and 
 (2) 100% of the principal amount of the Notes to be redeemed, 

plus, in either case, accrued and unpaid interest thereon to the redemption date. 

On or after the Par Call Date, the Issuer may redeem 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 the redemption date. 
 For
purposes of the foregoing provisions related to optional redemption, the following definitions are applicable: 
 “Business Day”
means each Monday, Tuesday, Wednesday, Thursday and Friday that is not a day on which banking institutions in The City of New York are authorized or obligated by law, regulation or executive order to close. 

“Treasury Rate” means, with respect to any redemption date, the yield determined by the Issuer in accordance with the following two
paragraphs. 
 The Treasury Rate shall be determined by the Issuer 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). In determining the Treasury Rate, the Issuer 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 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 

  
 Exhibit 1-4 












 
H.15 immediately longer than the Remaining Life – and shall interpolate to the 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 or any successor designation or publication is no longer
published, the Issuer 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 Par Call Date, as applicable. If there is no United States Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities
with a maturity date equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, the Issuer shall select the United States Treasury security with a maturity
date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Issuer 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 Issuer’s actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent
manifest error. 
 Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with the
depositary’s procedures) at least 10 days but not more than 60 days before the redemption date to each holder of Notes to be redeemed. 

In the case of a partial redemption, selection of the Notes for redemption will be made pro rata, by lot or by such other method as is
consistent with policies and procedures of the Trustee; and for so long as the Notes are held by DTC (or another depositary), the selection of the Notes for redemption shall be done in accordance with the policies and procedures of the depositary.
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. 

  
 Exhibit 1-5 












 Unless the Issuer 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. 
 Notwithstanding the provisions of
Section 12.2 of the Indenture, any notice of redemption of the Notes need not set forth the redemption price but only the manner of calculation thereof. The Issuer will notify the Trustee of the redemption price promptly after the calculation
thereof. The Trustee shall have no responsibility for such calculation. 
 In case an Event of Default (as defined in the Indenture) with
respect to the Notes shall have occurred and be continuing, the principal hereof and accrued and unpaid interest hereon may be declared, and upon such declaration shall become, due and payable, in the manner, with the effect and subject to the
conditions provided in the Indenture. 
 The Indenture contains provisions permitting the Issuer and the Trustee, with the consent of the
Holders of not less than a majority in aggregate principal amount of the Securities at the time Outstanding of all series to be affected (voting as one class), evidenced as in the Indenture provided, to execute supplemental indentures adding any
provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of any supplemental indenture or modifying in any manner the rights of the Holders of the Securities of each such series; provided, that no such
supplemental indenture shall, among other things, (i) extend the final maturity of any Security, or reduce the principal amount thereof or reduce the rate or extend the time of payment of any interest thereon, or reduce any amount payable on
the redemption thereof, or make the principal thereof or the interest thereon payable in any coin or currency other than that provided in the Securities or in accordance with the terms thereof, or impair or affect the rights of any Holder to
institute suit for the payment thereof, without the consent of the Holder of each Security so affected, or (ii) reduce the aforesaid percentage of Securities the Holders of which are required to consent to any such supplemental indenture
without the consent of the Holder of each Security so affected. It is also provided in the Indenture that, with respect to certain defaults or Events of Default, prior to any declaration accelerating the maturity of the Securities of any series, the
Holders of a majority in aggregate principal amount of the Outstanding Securities of such series (or, in the case of certain defaults or Events of Default, all or certain series of the Securities) may on behalf of the Holders of all the Securities
of such series (or all or certain series of the Securities, as the case may be) waive any such past default or Event of Default and its consequences. The preceding sentence shall not, however, apply to a default or Event of Default in respect of the
payment of the principal of or premium, if any, or interest on any of the Securities or a default or Event of Default in respect of a covenant or provision of the Indenture which cannot be modified or amended without the consent of the Holder of
each Security affected. Any such consent or waiver by the Holder of this Note (unless revoked as provided in the Indenture) shall be conclusive and binding upon such Holder and upon all future Holders and owners of this Note and any Notes which may
be issued in exchange or substitution herefor or on registration of transfer hereof, irrespective of whether or not any notation thereof is made upon this Note or such other Notes. 

No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Issuer,
which is absolute and unconditional, to pay the principal of and premium, if any, and interest on this Note in the manner, at the respective times, at the rate and in the coin or currency herein prescribed. 

  
 Exhibit 1-6 












 The Notes are issuable in registered form without coupons in denominations of $2,000 and any
integral multiple of $1,000 in excess thereof. Notes may be exchanged for a like aggregate principal amount of Notes of other authorized denominations upon surrender of the Notes to be exchanged at the agency of the Issuer maintained for that
purpose in the Borough of Manhattan, The City of New York in the manner and subject to the limitations provided in the Indenture, without charge except for any tax or other governmental charge that may be imposed in connection therewith. 

The Notes are not subject to any sinking fund. 

Upon due presentment for registration of transfer of this Note at the agency of the Issuer maintained for that purpose, a new Note or Notes of
authorized denominations for an equal aggregate principal amount will be issued to the transferee in exchange therefor, subject to the limitations provided in the Indenture, without charge except for any tax or other governmental charge that may be
imposed in connection therewith. 
 The Issuer, the Trustee and any authorized agent of the Issuer or the Trustee may deem and treat the
registered Holder hereof as the absolute owner of this Note (whether or not this Note shall be overdue and notwithstanding any notation of ownership or other writing hereon), for the purpose of receiving payment of, or on account of, the principal
hereof and premium, if any, and, subject to the provisions of the first paragraph hereof, interest hereon and for all other purposes, and neither the Issuer nor the Trustee nor any authorized agent of the Issuer or the Trustee shall be affected by
any notice to the contrary. 
 No recourse under or upon any obligation, covenant or agreement of the Issuer in the Indenture or in any
Note, or because of any indebtedness represented thereby, shall be had against any incorporator, stockholder, officer or director, as such, of the Issuer or of any successor entity, either directly or through the Issuer or any successor entity,
under any rule of law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise, all such liability being expressly waived and released by the acceptance hereof and as part of
the consideration for the issue hereof. 
 This Note shall be governed by and construed in accordance with the laws of the State of New
York, except as may otherwise be required by mandatory provisions of law. 
 Terms used in this Note which are defined in the Indenture
shall have the respective meanings assigned thereto in the Indenture, except that the terms “Business Day” and “business day,” as used in this Note, shall have the meanings set forth herein. 

The Indenture contains provisions whereby the Issuer may be discharged from its obligations with respect to the Notes, subject to exceptions,
if the Issuer deposits with the Trustee cash or U.S. Government Obligations in the amount and in the manner, and satisfies certain other conditions, as in the Indenture provided. 

  
 Exhibit 1-7 












 This Note shall not be valid or obligatory for any purpose until the certificate of
authentication hereon shall have been signed by or on behalf of the Trustee under the Indenture by manual or electronic signature of an authorized signatory of the Trustee. 

Offer to Purchase Upon Change of Control Triggering Event 

If a Change of Control Triggering Event occurs with respect to the Notes, the Issuer will make an offer (the “Change of Control
Offer”) to each Holder of Notes to repurchase (at such Holder’s option) all or any part (in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof, provided that any portion of a Note not repurchased must be in a
principal amount of $2,000 or an integral multiple of $1,000 in excess thereof) of such Holder’s Notes on the terms described below. In the Change of Control Offer, the Issuer will offer payment in cash equal to 101% of the principal amount of
the Notes to be repurchased, plus accrued and unpaid interest, if any, on such Notes (or portions thereof) to be repurchased to, but excluding, the date of repurchase (the “Change of Control Payment”); provided that, notwithstanding the
foregoing, payments of interest on the Notes that are due and payable on any dates falling on or prior to such a date of repurchase will be payable to the Holders of those Notes registered as such at the close of business on the relevant record
dates in accordance with their terms and the terms of the Indenture. Within 30 days following any Change of Control Triggering Event with respect to the Notes, the Issuer will mail (or otherwise transmit in accordance with applicable procedures of
DTC) (or cause to be mailed (or otherwise transmitted in accordance with applicable procedures of DTC)) a notice (the “Change of Control Purchase Notice”) to all Holders of Notes (with a copy to the Trustee) describing the transaction or
transactions constituting the Change of Control Triggering Event and offering to repurchase the Notes on the date specified in such notice, which date will be a business day no earlier than 10 days and no later than 60 days after the date such
notice is mailed (or otherwise transmitted in accordance with applicable procedures of DTC) (the “Change of Control Payment Date”). 

Holders electing to have a Note or portion thereof repurchased pursuant to a Change of Control Offer will be required to surrender the Note
(which, in the case of Notes in book-entry form, may be by book-entry transfer) to the Trustee (or to such other agent as may be appointed by the Issuer for such purpose) at the address specified in the applicable Change of Control Purchase Notice
prior to the close of business on the business day immediately preceding the applicable Change of Control Payment Date and to comply with other procedures set forth in such Change of Control Purchase Notice. As used in the preceding sentence and in
the last sentence of the preceding paragraph, the term “business day” means any day, other than a Saturday or Sunday, that is neither a legal holiday nor a day on which commercial banks are authorized or required by law, regulation or
executive order to close in The City of New York. 
 On any Change of Control Payment Date, the Issuer will, 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 Trustee (if the Trustee is acting as paying agent for the Notes) or any other duly appointed
paying agent for the Notes an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes properly tendered; and 



  
 Exhibit 1-8 













	 	(3)	 deliver the repurchased Notes or cause the repurchased Notes to be delivered to the Trustee for cancellation,
accompanied by an Officers’ Certificate stating the aggregate principal amount of repurchased Notes and that all conditions precedent provided for in the Notes and the Indenture relating to such Change of Control Offer and the repurchase of
Notes by the Issuer pursuant thereto have been complied with. 


 Interest on Notes and portions of Notes duly tendered for repurchase
pursuant to a Change of Control Offer will cease to accrue on and after the applicable Change of Control Payment Date, unless the Issuer shall have failed to accept such Notes and such portions of Notes for payment, failed to deposit the total
Change of Control Payment in respect thereof or failed to deliver the Officers’ Certificate, all as required by, and in accordance with, the immediately preceding sentence. 

The Issuer will agree to promptly pay, or will cause the Trustee (if the Trustee is acting as paying agent for the Notes) or another duly
appointed paying agent for the Notes to promptly pay (by application of funds deposited by the Issuer), to each Holder of Notes (or portions thereof) duly tendered and accepted for payment by the Issuer pursuant to a Change of Control Offer for the
Notes, the Change of Control Payment for such Notes, and the Issuer will cause the Trustee to promptly authenticate and mail (or deliver by book entry transfer, as applicable) to each such Holder a new Note equal in principal amount to the
unpurchased portion, if any, of the Notes surrendered by such Holder; provided that each such new Note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. The Issuer shall, or shall cause the Trustee to,
promptly mail (or cause to be delivered by book entry transfer, as applicable) to the Holders thereof any Notes not so accepted for payment by the Issuer. 

The Issuer will comply with the requirements of Rule 14e-1 under the Exchange Act and any other
securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of 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 the Change of Control Offer provisions of the Notes, the Issuer shall comply with those securities laws and regulations and shall not be deemed to have breached its obligations under the Change of Control
Offer provisions of the Notes by virtue of such conflict. 
 The Issuer will 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 time and otherwise in compliance with the requirements for an offer made by the Issuer and the third party purchases all Notes properly
tendered under its offer and delivers the repurchased Notes or causes the repurchased Notes to be delivered to the Trustee for cancellation on the applicable Change of Control Payment Date. In addition, the Issuer will not repurchase any Notes
pursuant to a Change of Control Offer if there has occurred and is continuing on the applicable Change of Control Payment Date an Event of Default under the Indenture (other than an Event of Default resulting from the Issuer’s failure to comply
with any of the provisions of 

  
 Exhibit 1-9 












 
the Notes or the Indenture relating to such Change of Control Offer or the repurchase of Notes pursuant thereto, including, without limitation, any default in payment of the Change of Control
Payment), including Events of Default arising with respect to other series of Securities outstanding under the Indenture. 
 The foregoing
Change of Control provisions of the Notes shall cease to be applicable (and any failure of the Issuer to comply therewith shall not constitute an Event of Default) if (i) the Indenture shall have ceased to be of further effect with respect to
the Notes pursuant to Section 10.1(A) of the Indenture (as used in this paragraph, “satisfaction and discharge”), or (ii) the Issuer shall be deemed to have paid and discharged the entire indebtedness on all of the Notes pursuant
to Section 10.1(B) of the Indenture (as used in this paragraph, “defeasance”) (it being understood that, in addition to the other conditions to defeasance set forth in the Indenture, any such defeasance shall not be effective until
the 121st day after the date of deposit referred to in subparagraph (a) of Section 10.1(B) of the Indenture), and, in the case of both clause (i) and (ii) of this sentence, the Issuer shall have satisfied the conditions set forth in
the Indenture to such satisfaction and discharge or such defeasance, as the case may be, and (without limitation to the foregoing) shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel (each of which comply with
Section 11.5 of the Indenture), each to the effect that all conditions precedent to such satisfaction and discharge or defeasance, as the case may be, provided for in the Indenture have been complied with. 

For purposes of the provisions set forth under this caption “Offer to Purchase Upon Change of Control Triggering Event,” the
following terms have the respective meanings specified below: 
 “Capital Stock” means, with respect to any Person, any and all
shares, interests, participations or other equivalents (however designated) in the equity of such Person (including, without limitation, (i) with respect to a corporation, common stock, preferred stock and any other capital stock,
(ii) with respect to a partnership, partnership interests (whether general or limited), and (iii) with respect to a limited liability company, limited liability company interests). 

“Change of Control” means the occurrence of any of the following: (a) the consummation of any transaction (including, without
limitation, any merger or consolidation) resulting in any “person” (as that term is used in Section 13(d)(3) of the Exchange Act) (other than the Issuer or any of its subsidiaries) becoming the “beneficial owner” (as defined
in Rules 13d-3 and 13d-5 under the Exchange Act), directly or indirectly, of more than 50% of the Issuer’s outstanding Voting Stock or other Voting Stock into which
the Issuer’s Voting Stock is reclassified, consolidated, exchanged or changed, measured by voting power rather than number of shares or (b) the direct or indirect sale, transfer, conveyance or other disposition (other than by way of merger
or consolidation), in one transaction or a series of related transactions, of all or substantially all of the properties or assets of the Issuer and its subsidiaries, taken as a whole, to one or more Persons (other than the Issuer or any of its
subsidiaries). Notwithstanding the foregoing, a transaction will not be deemed to be a Change of Control if (1) the Issuer becomes a direct or indirect wholly-owned subsidiary of a holding company and (2)(y) the direct or indirect holders of
the Voting Stock of such holding company immediately following that transaction are substantially the same as the holders of the Issuer’s Voting Stock immediately prior to that 

  
 Exhibit 1-10 












 
transaction or (z) immediately following that transaction no “person” (as that term is used in Section 13(d)(3) of the Exchange Act), other than a holding company satisfying
the requirements of this sentence, is the “beneficial owner” (as defined in Rules 13d-3 and 13d-5 under the Exchange Act), directly or indirectly, of more than
50% of the outstanding Voting Stock of such holding company, measured by voting power rather than number of shares. As used in this paragraph, the term “subsidiary” means, with respect to any Person (the “Parent”), any other
Person at least a majority of whose outstanding Voting Stock, measured by voting power rather than number of shares, is owned, directly or indirectly, at the date of determination by the Parent and/or one or more other subsidiaries of the Parent.

 “Change of Control Triggering Event” means the occurrence of both a Change of Control and a Rating Event. 

“Exchange Act” means the Securities Exchange Act of 1934, as amended, or any successor thereto. 

“Investment Grade Rating” means a rating equal to or higher than Baa3 (or the equivalent) by Moody’s and BBB- (or the equivalent) by S&P, and the equivalent investment grade credit rating from any replacement Rating Agency or Rating Agencies selected by the Issuer. 

“Moody’s” means Moody’s Investors Service, Inc. 

“Rating Agencies” means (a) each of Moody’s and S&P; and (b) if either of Moody’s or S&P ceases to rate
the Notes or fails to make a rating of the Notes publicly available for reasons outside of the Issuer’s control, a “nationally recognized statistical rating organization” (within the meaning of Rule
15c3-1(c)(2)(vi)(F) under the Exchange Act) selected by the Issuer (as certified by a Board Resolution delivered to the Trustee) as a replacement for Moody’s or S&P, or both of them, as the case may
be. 
 “Rating Event” means the rating on the Notes is lowered by each of the Rating Agencies and the Notes are rated below an
Investment Grade Rating by each of the Rating Agencies on any day within the 60-day period (which 60-day period shall be extended so long as the rating of the Notes is
under publicly announced consideration for a possible downgrade by either of the Rating Agencies) after the earlier of (a) the occurrence of a Change of Control and (b) public notice of the occurrence of a Change of Control or the
Issuer’s intention to effect a Change of Control; provided, however, that a Rating Event otherwise arising by virtue of a particular reduction in rating will not be deemed to have occurred in respect of a particular Change of Control (and thus
will not be deemed a Rating Event for purposes of the definition of “Change of Control Triggering Event”) if each Rating Agency making the reduction in rating to which this definition would otherwise apply does not announce or publicly
confirm or inform the Issuer in writing that the reduction was the result, in whole or in part, of any event or circumstance comprised of or arising as a result of, or in respect of, the applicable Change of Control (whether or not the applicable
Change of Control has occurred at the time of the Rating Event). The Trustee shall not be responsible for monitoring the ratings of the Notes nor shall it be charged with knowledge of such ratings. 

  
 Exhibit 1-11 












 “S&P” means S&P Global Ratings, a division of S&P Global Inc., and its
successors. 
 “Voting Stock” means, with respect to any specified “person” (as that term is used in
Section 13(d)(3) of the Exchange Act) as of any date, any Capital Stock of such person that is at the time entitled to vote generally in the election of the board of directors of such person or, if such person is not a corporation, any
governing body thereof performing a similar function. 
 As used under this caption “Offer to Purchase Upon Change of Control
Triggering Event,” all references to sections of the Exchange Act and to rules and regulations under the Exchange Act shall include any successor provisions thereto. 

For purposes of clarity, the Issuer confirms that (1) the provisions set forth under this caption “Offer to Purchase Upon Change of
Control Triggering Event” constitute covenants of the Issuer under the Indenture in respect of, and solely for the benefit of the Holders of, the Notes, (2) for purposes of Section 5.1(d), Section 5.10, Section 8.2 and any
other applicable provisions of the Indenture, the Notes shall be deemed to be the only series of Securities affected by such covenants or by any default in the performance, or breach, of any such covenants or any default or Event of Default
resulting therefrom or by any change therein or amendment thereto or waiver thereof and, without limitation to the foregoing, any such default or Event of Default shall be deemed to be a default or Event of Default, as the case may be, only with
respect to the Notes, (3) such covenants shall constitute a “right of repayment at the option of the Securityholder” for purposes of Section 8.2 of the Indenture and, without limitation to the foregoing, no supplemental indenture
entered into pursuant to Article Eight of the Indenture shall reduce the amount payable in respect of, or extend the time for payment of, any Notes pursuant to such covenants without the consent of the Holder of each Note so affected and
(4) any failure by the Issuer to pay all or any part of the Change of Control Payment as and when required pursuant to such covenants shall constitute an Event of Default with respect to the Notes under Section 5.1(b) of the Indenture.
