 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 4.00% Notes due 2029 (the “Offered Securities”).

 (2) The aggregate principal amount of the Offered Securities of such series that may be authenticated and delivered under the Indenture is
initially limited to $750,000,000, except for Offered Securities of such series authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, other Offered Securities of such series 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 of such series
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 of
such series, without the consent of the Holders of the Offered Securities of such series, so long as any such additional Offered Securities of such series have the same form and terms (except that any such additional Offered Securities of such
series 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 of such series 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 of such series pursuant to Section 10.1(A) or 10.1(B) of the Indenture; and provided, further, that no additional Offered Securities of such series 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 of such series are to be issuable only as Registered Securities without coupons. The Offered Securities of such
series shall be issued in book-entry form and represented by one or more Global Securities of such series, 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 the Global Securities of such series from time to time. Notwithstanding the foregoing, certificated Offered Securities of such series in definitive form may be issued in exchange for
Global Securities of such series under the circumstances contemplated by clauses (c)(i), (ii) and (iii) of Section 2.2A of the Indenture. 

(4) The Offered Securities of such series authorized hereby shall be originally issued on February 25, 2019 (the “Closing Date”)

0.650% of the principal amount of such Offered Securities.

persons, provided in the form of certificate evidencing the Offered Securities of such series attached as Exhibit 1 hereto. Interest on the Offered Securities of such series 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 of such series. 
 (7) The principal of and premium, if any, and interest on the Offered Securities of such series
shall be payable, the Offered Securities of such series may be surrendered for registration of transfer and exchange, and notices and demands to or upon the Company in respect of the Offered Securities of such series 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 of such series 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 of such series, 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 of such series, 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 of such series. 

(8) The Offered Securities of such series 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 of such series attached hereto as Exhibit 1, plus accrued
and unpaid interest on the principal amount of the Offered Securities of such series being redeemed to the applicable redemption date; provided, however, that payments of interest on the Offered Securities of such series that are due and payable on

principal of, or premium, if any, or interest on, the Offered Securities of such series, 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 of such series, 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 of such series, 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 of such series and in the certificates evidencing the Offered Securities

Security of such series 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 of such series attached hereto as
Exhibit 1, in excess of 100% of the principal amount of such Offered Security.

 Exhibit 1-1 













 
interest has been paid or duly provided for on this Note, in which case from February 25, 2019, 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

Depositary’s procedures as in effect from time to time. Notwithstanding the foregoing, if the date hereof is after May 1 or November 1, 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 February 25, 2019; 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 February 25, 2019. 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”) and a Fourth Supplemental Indenture thereto dated as of

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 













 At any time before August 15, 2029 (the date that is three months prior to the maturity date, which
date is referred to herein as the “Early Call Date”), the Notes will be redeemable, in whole at any time or from time to time in part, at the option of the Issuer at a redemption price equal to the greater of: 

 

	 	(1)	 100% of the principal amount of the Notes to be redeemed, and 



 

	 	(2)	 the sum of the present values of the remaining scheduled payments of principal and interest on the Notes to be
redeemed that would be due if such Notes matured on the Early Call Date but for the redemption (exclusive of any portion of the payments of interest accrued to the applicable Redemption Date) discounted to such Redemption 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, 



plus, in the case of both clause (1) and clause (2) above, accrued and unpaid interest on the principal amount of the Notes being redeemed to such
Redemption Date. 
 At any time on or after the Early Call Date, the Notes will be redeemable as a whole or in part, at the option of the Issuer, at a
redemption price equal to 100% of the principal amount of the Notes to be redeemed plus accrued and unpaid interest on the principal amount of the Notes being redeemed to such Redemption Date. 

Notwithstanding the foregoing, payments of interest on the Notes that are due and payable on or prior to a date fixed for redemption of Notes at the option of
the Issuer will be payable to the Holders of those Notes 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 such redemption shall be effected in
accordance with the terms and conditions set forth in the Indenture. 
 As used in this Note, the following terms have the meanings set forth below: 

“Treasury Rate” means, with respect to any Redemption Date for the Notes, the rate per annum equal to the semi-annual equivalent
yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date. 

“Comparable Treasury Issue” means, with respect to any Redemption Date for the Notes, the U.S. Treasury security selected by the
Independent Investment Banker as having a maturity comparable to the remaining term of the Notes (assuming, for such purpose, that the notes mature on the Early Call Date) to be redeemed that would be utilized, at the time of selection and in
accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the Notes to be redeemed. 

“Comparable Treasury Price” means, with respect to any Redemption Date for the Notes, (1) the average (as determined by the
Independent Investment Banker) of four Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest such Reference Treasury Dealer Quotations, or (2) if the Independent Investment Banker obtains fewer
than four but more than one such Reference Treasury Dealer Quotations, the average (as determined by the Independent Investment Banker) of all such quotations, or (3) if the Independent Investment Banker obtains only one such Reference Treasury
Dealer Quotation, such Reference Treasury Dealer Quotation. 

  
 Exhibit 1-3 













 “Independent Investment Banker” means, with respect to any Redemption Date for the
Notes, Goldman Sachs & Co. LLC and its successors, J.P. Morgan Securities LLC and its successors, Merrill Lynch, Pierce, Fenner & Smith Incorporated and its successors, or Morgan Stanley & Co. LLC and its successors,
whichever shall be selected by the Issuer, or, if all such firms or their respective successors, if any, to such firms, as the case may be, are unwilling or unable to select the Comparable Treasury Issue, an independent investment banking
institution of national standing appointed by the Issuer. 
 “Redemption Date” means, with respect to any Note or portion thereof
to be redeemed, the date fixed for such redemption pursuant to the Indenture and the Notes. 
 “Reference Treasury Dealers” means,
with respect to any Redemption Date for the Notes, Goldman Sachs & Co. LLC and its successors, J.P. Morgan Securities LLC and its successors, Merrill Lynch, Pierce, Fenner & Smith Incorporated and its successors, and Morgan
Stanley & Co. LLC and its successors (provided, however, that if any such firm or any such successor, as the case may be, shall cease to be a primary U.S. Government securities dealer in New York City (a “Primary Treasury
Dealer”), the Issuer shall substitute therefor another Primary Treasury Dealer). 
 “Reference Treasury Dealer Quotations”
means, with respect to each Reference Treasury Dealer and any Redemption Date for the Notes, the average, as determined by the Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a
percentage of its principal amount) quoted in writing to the Independent Investment Banker by that Reference Treasury Dealer at 5:00 p.m., New York City time, on the third Business Day preceding such Redemption Date. As used in the first paragraph
of this Note and in the immediately preceding sentence, the term “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. 
 Notice of any redemption will be mailed at least 10 days but not more than 60 days before
the applicable Redemption Date to each Holder of the Notes to be redeemed at the Holder’s registered address. If less than all of the Notes are to be redeemed at the option of the Issuer, the Notes to be redeemed shall be selected in accordance
with applicable procedures of DTC. 
 Unless the Issuer defaults in payment of the redemption price on the applicable Redemption Date
(including interest accrued to such Redemption Date), on and after such Redemption Date interest will cease to accrue on the Notes or portions of the Notes called for redemption on such Redemption Date. 

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. 

  
 Exhibit 1-4 













 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 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. 

  
 Exhibit 1-5 













 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 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 

  
 Exhibit 1-6 













 
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 cause to be mailed) 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 (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 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. 

  
 Exhibit 1-7 













 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 times 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. 
 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. 

  
 Exhibit 1-8 













 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 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. 

  
 Exhibit 1-9 













 “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). 
 “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 

  
 Exhibit 1-10 













 
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.
