RECITALS OF THE ISSUER AND THE GUARANTORS 

WHEREAS, the Issuer and the Guarantors have heretofore executed and delivered to the Trustee an Indenture, dated as of May 16, 2017 (the
“Original Indenture”), providing for the issuance from time to time of its unsecured senior debentures, notes or other evidences of Indebtedness (the “Securities”), to be issued in one or more series as provided in
the Original Indenture; 
 WHEREAS, Section 9.01 of the Original Indenture provides that the Issuer, each Guarantor and the Trustee may
from time to time enter into one or more indentures supplemental thereto to establish a new series of Securities and add certain provisions to the Original Indenture; 

WHEREAS, Sections 2.01 and 3.01 of the Original Indenture provide that the Issuer may enter into one or more indentures supplemental thereto
to establish the form and terms of a series of Securities issued pursuant to the Original Indenture; 
 WHEREAS, the Issuer, pursuant to the
foregoing authority, proposes in and by this First Supplemental Indenture (this “Supplemental Indenture” and, together with the Original Indenture, the “Indenture”) to supplement the Original Indenture insofar as it
will apply only to the series of securities to be known as the Issuer’s 3.600% Senior Notes due 2024 (the “Notes”) issued hereunder (and not to any other series); 

WHEREAS, the Issuer and the Guarantors have duly authorized the execution and delivery of this Supplemental Indenture; and 

WHEREAS, all things necessary have been done to make this Supplemental Indenture, the Notes and the Guarantees valid agreements of the Issuer
and the Guarantors, in accordance with their terms and the terms of the Original Indenture. 







 NOW, THEREFORE, for and in consideration of the premises and the covenants and agreements
contained herein, and for other good and valuable consideration the receipt of which is hereby acknowledged, the parties hereto agree as follows: 

ARTICLE I 
 3.600%
Senior Notes Due 2024 
 SECTION 1.01. Creation of Series; Establishment of Form. 

(1) There is hereby established a new series of Securities under the Indenture entitled “3.600% Senior Notes due 2024.” 

(2) The Notes, including the form of the certificate of authentication, shall be in substantially the form attached hereto as Exhibit A. 

(3) The Trustee shall authenticate and deliver the Notes for original issue in an aggregate principal amount of $650,000,000 upon an Issuer
Order for the authentication and delivery of the Notes. The Issuer may from time to time issue additional Notes in accordance with Sections 3.01 and 9.01 of the Original Indenture. Any additional Notes subsequently issued shall not be limited by the
aggregate principal amount of this Supplemental Indenture. The Notes issued originally hereunder, together with any additional Notes subsequently issued, shall be treated as a single series for purposes of the Indenture. 

(4) The Notes shall be issued in registered form without coupons. 

(5) The Notes shall not have a sinking fund. 

(6) The principal of the Notes shall be due on May 15, 2024. 

(7) The outstanding principal amount of the Notes shall bear interest at the rate of 3.600% per annum from May 16, 2017 or from the most
recent Interest Payment Date (as defined below) to which interest has been paid or duly provided for, as the case may be, payable semi-annually in arrears on May 15 and November 15 (each, an “Interest Payment Date”),
commencing on November 15, 2017, to the Persons in whose names the Notes are registered at the close of business on the Regular Record Date (as defined in Section 1.02) for such interest and at the Stated Maturity of the Notes, until the
principal thereof is paid or made available for payment. Interest on the Notes will be computed on the basis of a 360-day year comprised of twelve 30-day months. Any
such interest due on an Interest Payment Date that is not so punctually paid or duly provided for shall forthwith cease to be payable to the Holders on such Regular Record Date and may either be paid to the Person or Persons in whose name the Notes
are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Issuer pursuant to Section 3.07 of the Original Indenture, notice whereof shall be given to Holders of the Notes not
less than ten (10) days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange, if any, on which the Notes may be listed, and upon such notice as
may be required by any such exchange, all as more fully provided in the Original Indenture. 

  
 2 








 (8) The Notes shall be issued in denominations of $2,000 or any integral multiple of $1,000 in
excess thereof. 
 (9) If the Notes are redeemed, in whole at any time or in part from time to time, prior to March 15, 2024, the
Redemption Price for the Notes to be redeemed will be equal to the greater of: (i) 100% of the aggregate principal amount of the Notes to be redeemed, and (ii) an amount equal to the sum of the present value of (A) the payment on
March 15, 2024 of principal of the Notes to be redeemed and (B) the payment of the remaining scheduled payments through March 15, 2024 of interest on the Notes to be redeemed (excluding accrued and unpaid interest to the date of
redemption (the “Redemption Date”) and subject to the right of Holders on the relevant Record Date to receive interest due on the relevant Interest Payment Date) discounted from their scheduled date of payment to the Redemption Date on a

above cases, accrued and unpaid interest, if any, to, but excluding, such Redemption Date.

time or in part from time to time, on or after March 15, 2024, the Redemption Price for the Notes to be redeemed will equal 100% of the principal amount of such Notes to be redeemed plus accrued and unpaid interest, if any, to, but excluding,
such Redemption Date.

where the Redemption Date is an Interest Payment Date) shall be made at the office of the Paying Agent upon surrender of such Notes to the Paying Agent and (ii) payments of interest shall be made, at the option of the Issuer, subject to such

(3) The Trustee shall initially serve as the Paying Agent with respect to the Notes, with the Place of Payment initially being the Corporate
Trust Office. 
 SECTION 1.04. Global Securities. The Notes shall initially be issued in the form of one or more Global Securities
registered in the name of a nominee of the Depositary. Except under the limited circumstances described below, Notes represented by such Global Security or Global Securities shall not be exchangeable for, and shall not otherwise be issuable as,
Notes in definitive form. The Issuer has entered into a letter of representations with the Depositary in the form provided by the Depositary and the Trustee and each Paying Agent, Security Registrar or other agent is hereby authorized to act in
accordance with such letter and applicable Depositary procedures. The Global Securities described above may not be transferred except as a whole by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or
another nominee of the Depositary or to a successor Depositary or its nominee or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary, unless and until the Notes are exchanged in whole or in part
for Notes in definitive form. 

  
 6 








 Subject to the procedures of the Depositary, a Global Security representing the Notes shall be
exchangeable for Notes registered in the names of Persons other than the Depositary or its nominee only if (i) the Depositary notifies the Trustee and the Issuer in writing that it is no longer willing or able to properly discharge its
responsibilities as a Depositary for such Global Security and no qualified successor Depositary shall have been appointed by the Issuer within ninety (90) days of receipt by the Issuer of such notification, or if at any time the Depositary
ceases to be a clearing agency registered under the Exchange Act at a time when the Depositary is required to be so registered to act as such Depositary and no qualified successor Depositary shall have been appointed by the Issuer within ninety
(90) days after it becomes aware of such cessation, (ii) the Issuer executes and delivers to the Trustee an Issuer Order stating that the Issuer elects to terminate the book-entry system through the Depositary, or (iii) there shall
have occurred and be continuing an Event of Default with respect to such Global Security. Any Global Security that is exchangeable pursuant to the preceding sentence shall be exchangeable for the Notes it represents, as provided in the Original
Indenture. 
 SECTION 1.05. Redemption. 

(1) The Issuer shall send notice of any redemption pursuant to Section 1.01(9) not less than 30 nor more than 60 days prior to the
Redemption Date, to each Holder of the Notes to be redeemed. The Issuer shall deliver to the Trustee an Officers’ Certificate setting forth the Redemption Price with respect to the foregoing redemption no later than two (2) Business Days
prior to the Redemption Date. The Trustee shall have no responsibility for determining said Redemption Price on the Redemption Date, and from and after such date (unless the Issuer shall default in the payment of the Redemption Price and accrued
interest) such Notes shall cease to bear interest. 
 (2) Section 11.03 (Selection by Trustee of Securities to Be Redeemed) of the
Original Indenture is hereby amended and restated in its entirety as follows: 
 If less than all the 3.600% Senior Notes due
2024 are to be redeemed, the particular Notes to be redeemed shall be selected not more than 60 days prior to the Redemption Date by the Trustee, from the Outstanding Notes not previously called for redemption, by such method as the Trustee shall
deem fair and appropriate and in accordance with the applicable procedures of the Depositary, and which may provide for the selection for redemption of portions (equal to $1,000 or any integral multiple thereof) of the principal amount of Notes of a
denomination larger than $2,000; provided, however, that Notes registered in the name of the Issuer shall be excluded from any such selection for redemption until all Notes being redeemed and that are not so registered shall have been previously
selected for redemption. 
 The Trustee shall promptly notify the Issuer in writing of the Notes selected for redemption and,
in the case of any Notes selected for partial redemption, the principal amount thereof to be redeemed. 

  
 7 








 For all purposes of this Indenture, unless the context otherwise requires, all
provisions relating to the redemption of Notes shall relate, in the case of any Notes redeemed or to be redeemed only in part, to the portion of the principal amount of such Notes which has been or is to be redeemed. 

SECTION 1.06. Purchase of Notes Upon a Change of Control Triggering Event. 

(1) If a Change of Control Triggering Event occurs, unless the Issuer has exercised its right to redeem the Notes pursuant to Sections 1.01(9)
and 1.05 of this Supplemental Indenture or Article ELEVEN of the Original Indenture, the Issuer will make an offer to each Holder of Notes to repurchase all or any part (in excess of $2,000 and in integral multiples of $1,000 principal amount) of
that Holder’s Notes at a repurchase price in cash equal to 101% of the aggregate principal amount of Notes repurchased plus any accrued and unpaid interest on the Notes repurchased to but excluding the date of repurchase. Within 30 days
following any Change of Control Triggering Event or, at the Issuer’s option, prior to any Change of Control, but after the public announcement of the Change of Control, the Issuer will send a notice to each Holder and the Trustee describing the
transaction or transactions that constitute or may constitute the Change of Control Triggering Event and offering to repurchase Notes on the payment date specified in the notice, which date will be no earlier than 30 days and no later than 45 days
from the date such notice is sent. The notice shall, if sent prior to the date of consummation of the Change of Control, state that the offer to repurchase is conditioned on the Change of Control Triggering Event occurring on or prior to the payment
date specified in the notice. 
 (2) The Issuer will comply with the requirements of Rule 14e-1 under
the Exchange Act and any other securities laws and regulations to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Triggering Event. To the extent that the
provisions of any securities laws or regulations conflict with the Change of Control Triggering Event provisions of the Notes, the Issuer will comply with the applicable securities laws and regulations and will not be deemed to have breached its
obligations under the Change of Control Triggering Event provisions of the Notes by virtue of such conflict. 
 (3) On the Change of Control
Triggering Event payment date, the Issuer will, to the extent lawful: 
 (a) accept for payment all Notes or portions of
Notes properly tendered pursuant to the Issuer’s offer; 
 (b) deposit with the Paying Agent an amount equal to the
aggregate purchase price in respect of all Notes or portions of Notes properly tendered; and 
 (c) deliver or cause to be
delivered to the Trustee, the Notes properly accepted, together with an Officers’ Certificate stating the aggregate principal amount of Notes being purchase by the Issuer. 

  
 8 








 (4) The Paying Agent will promptly pay, from funds deposited by the Issuer for such purpose, to
each Holder of Notes properly tendered the purchase price for the Notes, and the Trustee will promptly authenticate and send (or cause to be transferred by book-entry) to each Holder a new note equal in principal amount to any unpurchased portion of
any Notes surrendered. 
 (5) The Issuer will not be required to make an offer to repurchase the Notes upon a Change of Control Triggering
Event if a third party makes an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Issuer and such third party purchases all Notes properly tendered and not withdrawn under its offer. 

SECTION 1.07. Additional Covenants. The following shall be additional covenants to the covenants set forth in the Original Indenture
for the benefit of the Notes only and shall be effective only so long as the Notes are Outstanding: 
 (1) Limitation on Liens. Parent shall
not, and shall not permit any of its Subsidiaries to, directly or indirectly, incur or suffer to exist any Lien, other than a Permitted Lien, securing Indebtedness upon any Capital Stock of any Significant Subsidiary of Parent that is owned,
directly or indirectly, by Parent or any of its Subsidiaries, in each case whether owned at the date of the original issuance of the Notes or thereafter acquired, or any interest therein or any income or profits therefrom unless it has made or will
make effective provision whereby the Outstanding Notes will be secured by such Lien equally and ratably with (or prior to) all other Indebtedness of Parent or any Subsidiary secured by such Lien. Any Lien created for the benefit of the Holders of
the Notes pursuant to the preceding sentence shall provide by its terms that such Lien will be automatically and unconditionally released and discharged upon release and discharge of the Lien. 

“Permitted Lien” means a Lien on the Capital Stock of a Significant Subsidiary to secure Indebtedness incurred to finance the
purchase price of such Capital Stock; provided that any such Lien may not extend to any other property of Parent or any other Subsidiary of Parent; and provided further that such Indebtedness matures within 180 days from the date such Indebtedness
was incurred. 
 (2) Limitation on Dispositions of Significant Subsidiaries. Parent shall not, and shall not permit any of its Subsidiaries
to, directly or indirectly, sell, transfer or otherwise dispose of, and will not permit any Significant Subsidiary to issue, any Capital Stock of any Significant Subsidiary. Notwithstanding the foregoing limitation, (a) Parent and its
Subsidiaries may sell, transfer or otherwise dispose of, and any Significant Subsidiary may issue, any such Capital Stock to any Subsidiary of Parent, (b) any Subsidiary of Parent may sell, transfer or otherwise dispose of, and any Significant
Subsidiary may issue, any such securities to Parent or another Subsidiary of Parent, (c) Parent and its Subsidiaries may sell, transfer or otherwise dispose of, and any Significant Subsidiary may issue, any such Capital Stock if the
consideration received is at least equal to the fair market value (as determined by the Board of Directors of Parent acting in good faith) of such Capital Stock, and (d) Parent and its Subsidiaries may sell, transfer or otherwise dispose of,
and any Significant Subsidiary may issue, any such securities if required by law or any regulation or order of any governmental or regulatory authority. Notwithstanding the foregoing, Parent may merge or consolidate any of its Significant
Subsidiaries into or with another one of its Significant Subsidiaries and may otherwise sell, transfer or otherwise dispose of its business pursuant to Article EIGHT of the Original Indenture.

 SECTION 1.08. Early Redemption for Tax Reasons. 

(1) The Notes may be redeemed at the option of the Issuer in whole, but not in part, at any time upon not less than 30 nor more than 60
days’ prior notice delivered electronically or by first-class mail, with a copy to the Trustee, to the registered address of each Holder, or otherwise delivered in accordance with the applicable procedures of the Depositary if: 

(a) on the occasion of the next payment due under the Notes, the Issuer, or any Guarantor, has or is reasonably likely to
become obliged to pay Additional Amounts (as defined in Section 1.09) as a result of any change in, or amendment to, the laws or regulations of a Taxing Jurisdiction (as defined in Section 1.09), or any change in the official application
or official interpretation of such laws or regulations, which change or amendment is announced and becomes effective on or after the date of issuance of the Notes; and 

(b) such obligation cannot be avoided by the Issuer, or the relevant Guarantor, taking reasonable measures available to it;

 provided that no such notice of redemption shall be given earlier than 90 days prior to the earliest date on which the Issuer, or a Guarantor, would be
obliged to pay such Additional Amounts were a payment in respect of the Notes then due. 
 (2) Prior to the giving of any notice of
redemption pursuant to the Indenture, the Issuer shall deliver to the Trustee an Officers’ Certificate of the Issuer stating that the Issuer is entitled to effect such redemption and setting forth a statement of facts showing that the
conditions precedent to the right of the Issuer so to redeem have occurred. Notes redeemed pursuant to this Section 1.08 will be redeemed at a Redemption Price equal to 100% of the principal amount of the Notes being redeemed plus accrued and
unpaid interest thereon to, but excluding, the date of redemption and all Additional Amounts due on the date of redemption. 
 SECTION 1.09.
Additional Amounts. With respect to any payments made by or on the behalf of the Issuer or a Guarantor in respect of the Notes or any Guarantee of the Notes, as applicable, the Issuer or such Guarantor will make all payments of principal of,
premium, if any, and interest on (whether on scheduled payment dates or upon acceleration) and the Redemption Price, if any, payable in respect of any Note without deduction or withholding for or on account of any present or future tax, duty, levy,
import, assessment or other governmental charge (including penalties, interest and other liabilities related thereto (“Taxes”) imposed, levied, collected, withheld or assessed by or on behalf of any jurisdiction in which the Issuer
or such Guarantor is incorporated or organized, engaged in business for tax purposes or otherwise resident for tax purposes, or any political subdivision thereof or taxing authority therein and any jurisdiction through which any payment is made on
behalf of the Issuer or any Guarantor (including the jurisdiction of any Paying Agent) (each, a “Taxing Jurisdiction”), upon or as a result of such payments, unless required by law or by the official interpretation or administration
thereof. 

  
 10 








 To the extent that any such Taxes are so levied or imposed, the Issuer or such Guarantor will pay
such additional amounts (“Additional Amounts”) in order that the net amount received by each Holder (including Additional Amounts), after withholding for or on account of such Taxes imposed upon or as a result of such payment, will
not be less than the amount that would have been received had such taxes not been imposed or levied; except that no such Additional Amounts shall be payable with respect to a payment made to a Holder or beneficial owner of a Note: 

(1) to the extent that such Taxes are imposed pursuant to Sections 1471 through 1474 of the Internal Revenue Code of 1986, as amended (the
“Code”), any current or future regulations or official interpretations thereof, any fiscal or regulatory legislation, rules or practices adopted pursuant to an intergovernmental agreement between a
non-U.S. jurisdiction and the United States, with respect to the forgoing or any agreements entered into pursuant to Section 1471(b)(1) of the Code (“FATCA”) and/or the UK’s International Tax
Compliance Regulations 2015; or 
 (2) to the extent that such Taxes would not have been so imposed, levied or assessed but for the existence
of some connection between such Holder or beneficial owner of such Note and the Taxing Jurisdiction imposing such Taxes other than the mere holding or enforcement of such Note or receipt of payments thereunder; or 

(3) to the extent that such Taxes would not have been so imposed, levied or assessed but for the failure of the Holders or beneficial owners of
such Note to comply with a reasonable written request by the Issuer (or its agent) to make a valid declaration of non-residence or any other claim or filing for exemption to which it is entitled (but only to
the extent it is legally entitled to do so); or 
 (4) that presents such Note for payment (where presentation is required) more than 30 days
after the date on which such payment became due and payable or the date on which payment of the Note is duly provided for and notice is given to Holders, whichever occurs later, except to the extent that the Holder or beneficial owner of such Note
would have been entitled to such Additional Amounts on presenting such Note on any date during such 30-day period; or 

(5) in the case of a payment made by or on behalf of the Issuer or any Guarantor organized under the laws of the United States, any state
thereof or the District of Columbia, with respect to any United States withholding taxes, so long as such withholding taxes are summarized in the prospectus supplement, dated May 11, 2017, in the discussion under the caption “Certain
Material Income Tax Consequences—United States Taxation” or the Issuer or such Guarantor (pursuant to Section 1.06 of the Original Indenture) provides reasonable notice regarding potential United States withholding taxes and requests
Holders and beneficial owners to provide applicable U.S. tax forms; or 
 (6) any combination of the above. 

As used herein and for purposes of the Indenture and the Notes, any reference to the principal of and interest on the Notes and the Redemption
Price, if any, shall be deemed to include a reference to any related Additional Amounts payable in respect of such amounts. The 

  
 11 








 
Issuer will also pay any stamp, registration, excise or property taxes and any other similar levies (including any interest and penalties related thereto) imposed by any Taxing Jurisdiction on
the execution, delivery, registration or enforcement of any of the Notes, the Guarantees, the Indenture or any other document or instrument referred to therein. 

SECTION 1.10. Events of Default. Section 5.01 of the Original Indenture setting forth the “Events of Default” is
hereby amended and restated in its entirety for the benefit of the Notes only as follows: 
 “Event of Default,” whenever
used herein with respect to the Notes, means any one of the following events (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be affected by operation of law or pursuant to any judgment, decree or

(including Additional Amounts) upon any Note when it becomes due and payable, and continuance of such default for a period of 30 days; or 

(2) a default in the payment of the principal of or premium, if any, on any Note at its Maturity; or 

(3) a default in the performance, or breach, of any other covenant of the Issuer or any Guarantor (other than a covenant a default in whose
performance or whose breach is elsewhere in this Section specifically dealt with or which has been expressly included in the Indenture solely for the benefit of Securities other than the Notes), and continuance of such default or breach for a period
of 60 days after there has been given, by registered or certified mail, to the Issuer or such Guarantor by the Trustee or to the Issuer or such Guarantor and the Trustee by the Holders of at least 25% in principal amount of the Outstanding Notes a
written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a “Notice of Default” hereunder; or 

(4) a default under any Indebtedness by the Issuer, any Guarantor or any of their respective subsidiaries that results in acceleration of the
maturity of such Indebtedness, or failure to pay any such Indebtedness at maturity, in an aggregate amount greater than $50.0 million or its foreign currency equivalent at the time, provided that the cure of such default shall remedy such Event
of Default under this Section 1. 10(4); or 
 (5) the entry by a court having jurisdiction in the premises of (A) a decree or order
for relief in respect of Parent, the Issuer or any Significant Subsidiary in an involuntary case or proceeding under any applicable Bankruptcy Law or (B) a decree or order adjudging Parent, the Issuer or any Significant Subsidiary a bankrupt or

of Parent, the Issuer or any Significant Subsidiary or of any substantial part of their property, or ordering the winding up or liquidation of its affairs, and the continuance of any such decree or order for relief or any such other decree or order
unstayed and in effect for a period of 90 consecutive days; or 

  
 12 








 (6) the commencement by Parent, the Issuer or any Significant Subsidiary of a voluntary case or
proceeding under any applicable Bankruptcy Law or of any other case or proceeding to be adjudicated a bankrupt or insolvent, or the consent by it to the entry of a decree or order for relief in respect of Parent, the Issuer or any Significant
Subsidiary in an involuntary case or proceeding under any applicable Bankruptcy Law or to the commencement of any bankruptcy or insolvency case or proceeding against it, or the filing by it of a petition or answer or consent seeking reorganization
or relief under any applicable Bankruptcy Law, or the consent by it to the filing of such petition or to the appointment of or taking possession by a Custodian of Parent, the Issuer or any Significant Subsidiary of any substantial part of its
property, or the making by it of an assignment for the benefit of creditors, or the admission by it in writing of its inability to pay its debts generally as they become due, or the taking of corporate action by Parent, the Issuer or any Significant
Subsidiary in furtherance of any such action, or the taking of any comparable action under any foreign laws relating to insolvency; or 
 (7)
any Guarantee with respect to the Notes shall for any reason cease to be, or shall for any reason be asserted in writing by any Guarantor not to be, in full force and effect and enforceable in accordance with its terms, except as contemplated by the
Indenture and any such Guarantee. 
 SECTION 1.11. Notice of Defaults. 

Section 6.02 (Notice of Defaults) of the Original Indenture is hereby amended and restated in its entirety for the benefit of the Notes

 Within 90 days after the Trustee has knowledge of the occurrence of any default hereunder with respect to the Notes, the
Trustee shall send to all Holders of the Notes, as their names and addresses appear in the Security Register, notice of such default hereunder known to a Responsible Officer of the Trustee, unless such default shall have been cured or waived;
provided, however, that, except in the case of a default in the payment of the principal of, premium, if any, or interest on any Note or in the payment of any sinking fund or analogous obligation installment with respect to the Notes, the Trustee
shall be protected in withholding such notice if and so long as the board of directors, the executive committee or a trust committee of directors or Responsible Officers of the Trustee in good faith determines that the withholding of such notice is
in the interest of the Holders of the Notes; and provided, further, that in the case of any default of the character specified in Section 1.10(3) with respect to the Notes, no such notice to Holders shall be given until at least 30 days after
the occurrence thereof. For the purpose of this Section, the term “default” means any event which is, or after notice or lapse of time or both would become, an Event of Default with respect to the Notes. 

SECTION 1.12. Legal Defeasance and Discharge and Covenant Defeasance. Section 4.03 and Section 4.04 of the Original Indenture
do hereby apply to all of the outstanding Notes; provided, that, solely with respect to the Notes, the reference to Section 5.01(4) in Section 4.04 shall be amended to be a reference to Section 1.10(3) and provided, further, that
clause (4) of Section 5.01, as such Section 5.01 shall have been amended by this Supplemental Indenture, shall be subject to Covenant Defeasance under Section 4.04 of the Original Indenture.

 3.600%
Senior Note due 2024 
 This global security certificate represents one of a duly authorized issue of securities of the Issuer (herein
called the “Securities”), issued and to be issued in one or more series under an Indenture, dated as of May 16, 2017 (herein called the “Original Indenture”), as supplemented by the First Supplemental Indenture, dated as of
May 16, 2017 (herein called the “First Supplemental Indenture”) (such Original Indenture, together with the First Supplemental Indenture, the “Indenture”), among the Issuer and WILLIS TOWERS WATSON PUBLIC LIMITED COMPANY, a
company organized and existing under the laws of Ireland and parent company of the Issuer (without any of its consolidated subsidiaries, “Parent,” and together with its consolidated subsidiaries, the “Company”), WILLIS TOWERS
WATSON SUB HOLDINGS UNLIMITED COMPANY, a company organized and existing under the laws of Ireland, WILLIS NETHERLANDS HOLDINGS B.V., a company organized under the laws of the Netherlands, WILLIS INVESTMENT UK HOLDINGS LIMITED, a company organized
and existing under the laws of England and Wales, TA I LIMITED, a company organized and existing under the laws of England and Wales, WTW BERMUDA HOLDINGS LTD., a company organized and existing under the laws of Bermuda, TRINITY ACQUISITION PLC, a
company organized and existing under the laws of England and Wales, and WILLIS GROUP LIMITED, a company organized and existing under the laws of England and Wales, as guarantors (collectively, the “Guarantors”) and WELLS FARGO BANK,
NATIONAL ASSOCIATION, as Trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights,
duties and immunities thereunder of the Issuer, the Guarantors, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Note is one of the series designated on
the face hereof (herein called the “Notes”). 
 The Notes may be redeemed at the option of the Issuer in whole, but not in part,
at any time upon not less than 30 nor more than 60 days’ prior notice delivered electronically or by first-class mail, with a copy to the Trustee, to the registered address of each Holder or otherwise delivered in accordance with the applicable
procedures of the Depositary, if: 
 (i) on the occasion of the next payment due under the Notes, the Issuer, or any
Guarantor, has or will become obliged to pay Additional Amounts (as defined below) as a result of any change in, or amendment to, the laws or regulations of the Taxing Jurisdiction (defined below), or any change in the official application or
official interpretation of such laws or regulations, which change or amendment is announced and becomes effective on or after the date of issuance of the Notes; and 

(ii) such obligation cannot be avoided by the Issuer, or the relevant Guarantor, taking reasonable measures available to it;








 provided that no such notice of redemption shall be given earlier than 90 days prior to the
earliest date on which the Issuer, or a Guarantor, would be obliged to pay such Additional Amounts were a payment in respect of the Notes then due. 

Upon the occurrence of a Change of Control Triggering Event, unless the Issuer has exercised its right to redeem the Notes pursuant to
Sections 1.01 and 1.05 of the First Supplemental Indenture or Article ELEVEN of the Original Indenture, each Holder will have the right to require that the Issuer repurchase all or any part (in excess of $2,000 and in integral multiples of $1,000
principal amount) of that Holder’s Notes at a repurchase price in cash equal to 101% of the aggregate principal amount of Notes repurchased plus any accrued and unpaid interest on the Notes repurchased to but excluding the date of repurchase.
Within 30 days following any Change of Control Triggering Event or, at the Issuer’s option, prior to any Change of Control, but after the public announcement of the Change of Control, the Issuer will send a notice to each Holder describing the
transaction or transactions that constitute or may constitute the Change of Control Triggering Event and offering to repurchase Notes on the payment date specified in the notice, which date will be no earlier than 30 days and no later than 45 days
from the date such notice is sent. The notice shall, if sent prior to the date of consummation of the Change of Control, state that the offer to repurchase is conditioned on the Change of Control Triggering Event occurring on or prior to the payment
date specified in the notice. 
 The Issuer will comply with the requirements of Rule 14e-1 under
the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and any other securities laws and regulations to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a
Change of Control Triggering Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control Triggering Event provisions of the Notes, the Issuer will comply with the applicable securities laws and
regulations and will not be deemed to have breached its obligations under the Change of Control Triggering Event provisions of the Notes by virtue of such conflict. 

On the Change of Control Triggering Event payment date, the Issuer will, to the extent lawful: 

(i) accept for payment all Notes or portions of Notes properly tendered pursuant to the Issuer’s offer; 

(ii) deposit with the Paying Agent an amount equal to the aggregate purchase price in respect of all Notes or portions of Notes
properly tendered; and 
 (iii) deliver or cause to be delivered to the Trustee, the Notes properly accepted, together with
an Officers’ Certificate stating the aggregate principal amount of Notes being purchase by the Issuer. 
 The Paying Agent will
promptly pay, from funds deposited by the Issuer for such purpose, to each Holder of Notes properly tendered the purchase price for the Notes, and the Trustee will promptly authenticate and send (or cause to be transferred by book-entry) to each
Holder a new note equal in principal amount to any unpurchased portion of any Notes surrendered. 

  
 2 








 The Issuer will not be required to make an offer to repurchase the Notes upon a Change of Control
Triggering Event if a third party makes an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Issuer and such third party purchases all Notes properly tendered and not withdrawn under its
offer. 
 The definitions of certain terms used in the paragraphs above are listed below. 

“Change of Control” means the occurrence of any of the following: 

(i) the consummation of any transaction (including without limitation, any merger or consolidation) the result of which is that
any person (including any “person” (as that term is used in Section 13(d)(3) of the Exchange Act)) becomes the “beneficial owner” (as defined in Rules 13d-3 and 13d-5 under the Exchange Act), directly or indirectly, of Capital Stock representing more than 50% of the aggregate ordinary voting power represented by the issued and outstanding Capital Stock of Parent; 

(ii) the first day on which Parent ceases to own, directly or indirectly, at least 80% of the outstanding Capital Stock of the
Issuer; or 
 (iii) the adoption of a plan relating to the liquidation or dissolution of Parent. 

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

“Investment Grade” means a rating of Baa3 or better by Moody’s (or its equivalent under any successor rating categories of
Moody’s) and BBB- or better by S&P (or its equivalent under any successor rating categories of S&P) (or, in each case, if such Rating Agency ceases to rate the Notes for reasons outside of the
Company’s control, the equivalent investment grade credit rating from any Rating Agency selected by the Company as a replacement Rating Agency). 

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

“Officers’ Certificate” means a certificate signed by the Chairman of the Board, the Chief Executive Officer, the President, a
director, a Vice President, the Chief Financial Officer, the Group General Counsel and by the Treasurer, an Assistant Treasurer, the Secretary or an Assistant Secretary of the Issuer or any Guarantor, as applicable, and delivered to the Trustee.

 “Rating Agency” means: 

(i) each of Moody’s and S&P; and 

(ii) 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 Company’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 Company as a replacement agency
for Moody’s or S&P, or both, as the case may be.

 “Ratings Decline” means at any time during the period commencing on the earlier of,
(i) the occurrence of a Change of Control or (ii) public notice of the occurrence of a Change of Control or the intention by Parent to effect a Change of Control, and ending 60 days thereafter (which period shall be extended so long as the

 Prior to the giving of any notice of redemption pursuant to the Indenture, the Issuer shall
deliver to the Trustee an Officers’ Certificate of the Issuer stating that the Issuer is entitled to effect such redemption and setting forth a statement of facts showing that the conditions precedent to the right of the Issuer so to redeem
have occurred. Notes redeemed pursuant to this provision will be redeemed at a Redemption Price equal to 100% of the principal amount of Notes redeemed plus accrued and unpaid interest thereon to, but excluding, the date of redemption and all
Additional Amounts due on the date of redemption. 
 With respect to any payments made by or on the behalf of the Issuer or a Guarantor in
respect of the Notes or any Guarantee of the Notes, as applicable, the Issuer or such Guarantor will make all payments of principal of, premium, if any, and interest on (whether on scheduled payment dates or upon acceleration) and the Redemption
Price, if any, payable in respect of any Note without deduction or withholding for or on account of any present or future tax, duty, levy, import, assessment or other governmental charge (including penalties, interest and other liabilities related
thereto (“Taxes”) imposed, levied, collected, withheld or assessed by or on behalf of any jurisdiction in which the Issuer or such Guarantor is incorporated or organized, engaged in business for tax purposes or otherwise resident
for tax purposes, or any political subdivision thereof or taxing authority therein and any jurisdiction through which any payment is made on behalf of the Issuer or any Guarantor (including the jurisdiction of any Paying Agent) (each, a
“Taxing Jurisdiction”), upon or as a result of such payments, unless required by law or by the official interpretation or administration thereof. 

To the extent that any such Taxes are so levied or imposed, the Issuer or such Guarantor will pay such additional amounts (“Additional
Amounts”) in order that the net amount received by each Holder (including Additional Amounts), after withholding for or on account of such Taxes imposed upon or as a result of such payment, will not be less than the amount that would have
been received had such taxes not been imposed or levied; except that no such Additional Amounts shall be payable with respect to a payment made to a Holder or beneficial owner of a Note: 

(i) to the extent that such Taxes are imposed pursuant to Sections 1471 through 1474 of the Internal Revenue Code of 1986, as
amended (the “Code”), any current or future regulations or official interpretations thereof, any fiscal or regulatory legislation, rules or practices adopted pursuant to an intergovernmental agreement between a non-U.S. jurisdiction and the United States, with respect to the forgoing or any agreements entered into pursuant to Section 1471(b)(1) of the Code (“FATCA”) and/or the UK’s International Tax
Compliance Regulations 2015; or 

  
 4 








 (ii) to the extent that such Taxes would not have been so imposed, levied or
assessed but for the existence of some connection between such Holder or beneficial owner of such Note and the Taxing Jurisdiction imposing such Taxes other than the mere holding or enforcement of such Note or receipt of payments thereunder; or 

(iii) to the extent that such Taxes would not have been so imposed, levied or assessed but for the failure of the Holders or
beneficial owners of such Note to comply with a reasonable written request by the Issuer (or its agent) to make a valid declaration of non-residence or any other claim or filing for exemption to which it is
entitled (but only to the extent it is legally entitled to do so); or 
 (iv) that presents such Note for payment (where
presentation is required) more than 30 days after the date on which such payment became due and payable or the date on which payment of the Note is duly provided for and notice is given to Holders, whichever occurs later, except to the extent that
the Holder or beneficial owner of such Note would have been entitled to such Additional Amounts on presenting such Note on any date during such 30-day period; or 

(v) in the case of a payment made by or on behalf of the Issuer or any Guarantor organized under the laws of the United States,
any state thereof or the District of Columbia, with respect to any United States withholding taxes, so long as such withholding taxes are summarized in the prospectus supplement, dated May 11, 2017, in the discussion under the caption
“Certain Material Income Tax Consequences—United States Taxation” or the Issuer or such Guarantor (pursuant to Section 1.06 of the Original Indenture) provides reasonable notice regarding potential United States withholding taxes
and requests Holders and beneficial owners to provide applicable U.S. tax forms; or 
 (vi) any combination of the above.

 As used herein and for purposes of this Note, any reference to the principal of and interest on the Notes and the Redemption Price, if
any, shall be deemed to include a reference to any related Additional Amounts payable in respect of such amounts. The Issuer will also pay any stamp, registration, excise or property taxes and any other similar levies (including any interest and
penalties related thereto) imposed by any Taxing Jurisdiction on the execution, delivery, registration or enforcement of any of the Notes, the Indenture or any other document or instrument referred to therein. 

The Issuer may, from time to time, without notice to or the consent of the Holders of the Notes, increase the principal amount of the Notes
under the Indenture and issue such increased principal amount (or any portion thereof), in which case any additional Notes so issued will have the same form and terms (other than the date of issuance and the issue price and, under certain
circumstances, the date from which interest thereon will begin to accrue and the initial Interest Payment Date), and will carry the same right to receive accrued and unpaid interest, as the Notes previously issued, and such additional Notes will
form a single series with the previously issued Notes, including for voting purposes.

redeemed, and (ii) an amount equal to the sum of the present value of (A) the payment on March 15, 2024 of principal of the Notes to be redeemed and (B) the payment of the remaining scheduled payments through March 15, 2024
of interest on the Notes to be redeemed (excluding accrued and unpaid interest to the date of redemption (the “Redemption Date”) and subject to the right of Holders on the relevant Record Date to receive interest due on the relevant
Interest Payment Date) discounted from their scheduled date of payment to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day
months) using a discount rate equal to the Treasury Rate plus 20 basis points plus, in each of the above cases, accrued and unpaid interest, if any, to, but excluding, such Redemption Date. 

If the Notes are redeemed on or after March 15, 2024, the Redemption Price for the Notes to be redeemed will equal 100% of the principal
amount of such Notes to be redeemed plus accrued and unpaid interest, if any, to, but excluding, such Redemption Date.

“Comparable Treasury Price” means, with respect to any Redemption Date for the Notes, (1) the average of five Reference

“Treasury Constant Maturities,” for the maturity corresponding to the Comparable Treasury Issue (if no maturity is within three months before or after the remaining term of the Notes yields for the two published maturities most closely
corresponding to the Comparable Treasury Issue will be determined and the Treasury Rate will be interpolated or extrapolated from such yields on a straight line basis, rounding to the nearest month); or (b) if such release (or any successor
release) is not published during the week preceding the calculation date or does not contain such yields, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the
