 WHEREAS, the Issuer, pursuant to the
foregoing authority, proposes in and by this Third 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 two series of securities to be known as the Issuer’s 3.500% Senior Notes due 2021 (the “2021 Notes”) and the 4.400% Senior Notes due 2026 (the “2026 Notes” and together with the 2021 Notes,

 WHEREAS, the Issuer and the Guarantors have duly authorized

 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 
 3.500%

substantially the respective forms attached hereto as Exhibits A and B. 
 (3) The Trustee shall authenticate and deliver the Notes for
original issue in an aggregate principal amount of $450,000,000 for the 2021 Notes and $550,000,000 for the 2026 Notes 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 of either series subsequently issued shall not be limited by the aggregate principal amount of this Supplemental Indenture. Each series of Notes issued originally
hereunder, together with any additional Notes of such series 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 2021 Notes shall be due on September 15, 2021 and the principal of the 2026 Notes shall be due on March 15,
2026. 
 (7) The outstanding principal amount of the 2021 Notes shall bear interest at the rate of 3.500% per annum, and the
outstanding principal amount of the 2026 Notes shall bear interest at the rate of 4.400% per annum, both from March 22, 2016 or from the most recent Interest Payment Date (as defined below) to which interest has been paid or duly provided

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

Original Indenture, notice whereof shall be given to Holders of the Notes not less than ten (10) days prior to such

plus, in each of the above cases, accrued and unpaid interest, if any, to such Redemption Date. 
 If the 2021 Notes are redeemed, in whole
at any time or in part from time to time, on or after August 15, 2021, the Redemption Price for the 2021 Notes to be redeemed will equal 100% of the principal amount of such 2021 Notes to be redeemed plus accrued and unpaid interest, if any, to

semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) using a discount rate equal to the Treasury Rate plus 40 basis points plus, in each of the above cases, accrued and unpaid interest, if any, to such Redemption Date. 

If the 2026 Notes are redeemed, in whole at any time or in part from time to time, on or after December 15, 2025, the Redemption Price

(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. Each series of 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. 
 Subject to the procedures of the Depositary, a Global Security representing the Notes of
either series shall be exchangeable for Notes of such series 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. 

  
 7 

 (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 3.500% Senior Notes due 2021
and/or the 4.400% Senior Notes due 2026 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. 

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 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 

  
 8 

 
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. 

(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 

  
 9 

 
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 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 (a “Change in Tax Law”); and 

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

  
 10 

 provided that no such notice of redemption shall be given earlier than 90 days prior to the earliest date on
which the Issuer 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. 

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 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 

(2) 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 

  
 11 

 (3) 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 
 (4) where such
withholding or deduction is imposed on a payment to or for an individual and is required to be made pursuant to Council Directive 2003/48/EC on the taxation of savings income or any other directive or law implementing or complying with, or
introduced in order to conform to, such Directive, the ECOFIN Council meeting of 26-27 November 2000 or any other law implementing or complying with any arrangement entered into between the EU member states and certain third countries and
territories in connection with such Directive (including, for the avoidance of doubt, any replacement directive or law); or 
 (5) that
presents such Note for payment (where presentation is required) by or on behalf of the Holders of such Note to any Paying Agent if such withholding or deduction of such Taxes could have been avoided by presenting such Note to another Paying Agent in
a member state of the European Union; 
 (6) in the case of a payment made by or on behalf of a 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 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 
 (7) 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 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 of each series, 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 order of any court or any order, rule or regulation of any administrative or governmental body): 

  
 12 

 (1) a default in payment of interest (including Additional Amounts) upon any Note of such series
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 of such series 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 of such series), 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 of such series 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 insolvent, or approving as properly filed a petition seeking reorganization, arrangement, adjustment or composition of or in respect of Parent, the Issuer or any Significant Subsidiary under any
applicable Bankruptcy Law, or appointing a Custodian 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 
 (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 

  
 13 

 (7) any Guarantee with respect to the Notes of such series 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
only as follows: 
 Within 90 days after the Trustee has knowledge of the occurrence of any default hereunder with respect to the Notes of a
series, the Trustee shall send to all Holders of such 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 such Note or in the payment of any sinking fund or analogous obligation installment with respect to such 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 such Notes; and provided, further, that in the case of any default of the character specified in Section 1.10(3) with respect to such 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 such 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.

be, shall consolidate with or merge into another Person or convey, transfer or lease its properties and assets substantially as an entirety to any Person, the Person formed by such consolidation or into which the Issuer or such Guarantor, as the
case may be, is merged or the Person which acquires by conveyance or transfer, or which leases, the properties and assets of the Issuer or such Guarantor, as the case may be, substantially as an entirety shall (i) in the case of the Issuer or
any Guarantor that is not

Securities and immediately after such transaction no Event of Default shall have happened or be continuing; and 
 (2) the Issuer or such
Guarantor, as the case may be, has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that (a) such consolidation, merger, conveyance, transfer or lease and, if a supplemental indenture is required in

the same manner and at the same time as would have been the case if such consolidation, merger, conveyance, transfer or lease had not occurred.

amendment is announced and becomes effective on or after the date of issuance of the Notes (a “Change in Tax Law”); and

of redemption shall be given earlier than 90 days prior to the earliest date on which the Issuer 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 Third 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. 
 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 Notes shall be reduced by both Rating Agencies and (b) the Notes shall be rated below Investment Grade by each of the Rating Agencies.

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

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 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 

(ii) 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 

 (iii) 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 

(iv) where such withholding or deduction is imposed on a payment to or for an individual and is required to be made pursuant to
Council Directive 2003/48/EC on the taxation of savings income or any other directive or law implementing or complying with, or introduced in order to conform to, such Directive, the ECOFIN Council meeting of 26-27 November 2000 or any other
law implementing or complying with any arrangement entered into between the EU member states and certain third countries and territories in connection with such Directive (including, for the avoidance of doubt, any replacement directive or law); or

 (v) that presents such Note for payment (where presentation is required) by or on behalf of the Holders of such Note to
any Paying Agent if such withholding or deduction of such Taxes could have been avoided by presenting such Note to another Paying Agent in a member state of the European Union; 

(vi) in the case of a payment made by or on behalf of a 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 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 
 (vii) 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. 

  
 5 

 No sinking fund is provided for the Notes. The Notes are subject to redemption upon not less than
30 nor more than 60 days’ notice given as provided in the Indenture, as a whole at any time, or in part from time to time. 
 If the
Notes are redeemed prior to August 15, 2021, 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 2021 Notes to be redeemed, and (ii) an amount equal to
the sum of the present value of (A) the payment on August 15, 2021 of principal of the Notes to be redeemed and (B) the payment of the remaining scheduled payments through August 15, 2021 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 35 basis points plus, in each of the above cases, accrued and
unpaid interest, if any, to such Redemption Date. 
 If the Notes are redeemed on or after August 15, 2021, 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 such Redemption Date.

corporate debt securities of comparable maturity to the remaining term of such Notes. 
 “Comparable Treasury Price” means, with
respect to any Redemption Date for the Notes, (1) the average of five Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (2) if the Independent

“Independent Investment Banker” means one of the Reference Treasury Dealers that the Issuer appoints to act as the Independent
Investment Banker from time to time.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any Redemption Date, 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 at 5:00 p.m.,
New York City time, on the third Business Day preceding such Redemption Date. 

  
 6

Governors of the Federal Reserve System and which establishes yields on actively traded U.S. Treasury securities adjusted to constant maturity under the caption “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 Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to
the Comparable Treasury Price for such Redemption Date. The Treasury Rate will be calculated on the third Business Day preceding the Redemption Date. 

In the event of redemption of this Note in part only, a new Note or Notes of like tenor for the unredeemed portion hereof will be issued in
the name of the Holder hereof upon the cancellation hereof.

provisions for defeasance at any time of the entire Indebtedness of this Note or certain restrictive covenants and Events of Default with respect to this Note, in each case upon compliance with certain conditions set forth in the Indenture. 

If an Event of Default with respect to the Notes shall occur and be continuing, the principal of the Notes may be declared due and payable in
the manner and with the effect provided in the Indenture. 
 The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the Issuer and the Guarantors and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Issuer, the Guarantors and the

in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Issuer with certain provisions of the Indenture and certain past defaults under the
Indenture and their consequences. Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in
exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note. 

  
 7 

 As provided in and subject to the provisions of the Indenture, the Holder of this Note shall not
have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing
Event of Default with respect to the Notes, the Holders of not less than a majority in principal amount of the Notes at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default
as Trustee and offered the Trustee indemnity, and the Trustee shall not have received from the Holders of a majority in principal amount of Notes at the time Outstanding a direction inconsistent with such request, and shall have failed to institute
any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Note for the enforcement of any payment of principal hereof (or premium, if
any) or interest hereon on or after the respective due dates expressed or provided for herein. 
 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 any premium and interest on this Note at the times, place and rate, and in the coin or
currency, herein prescribed. 
 As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Note
is registrable in the Security Register, upon surrender of this Note for registration of transfer at the office or agency of the Issuer in any place where the principal of and any premium and interest on this Note are payable, duly endorsed by, or

authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 
 The
Notes are issuable only in registered form without coupons in denominations of $2,000 or any integral multiple of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, the Notes are exchangeable

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 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 (a “Change in Tax Law”); and 

(ii) such obligation cannot be avoided by the Issuer 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 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 Third 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

than 30 days and no later than 45 days from the date such notice is send. 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.

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

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.

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:

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

(iv) where such withholding or deduction is imposed on a payment to or for an individual and is required to be made pursuant to
Council Directive 2003/48/EC on the taxation of savings income or any other directive or law implementing or complying with, or introduced in order to conform to, such Directive, the ECOFIN Council meeting of 26-27 November 2000 or any other
law implementing or complying with any arrangement entered into between the EU member states and certain third countries and territories in connection with such Directive (including, for the avoidance of doubt, any replacement directive or law); or

any Paying Agent if such withholding or deduction of such Taxes could have been avoided by presenting such Note to another Paying Agent in a member state of the European Union; 

(vi) in the case of a payment made by or on behalf of a 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 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 
 (vii) 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

(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.

 No sinking fund is provided for the Notes. The Notes are subject to redemption upon not less than
30 nor more than 60 days’ notice given as provided in the Indenture, as a whole at any time, or in part from time to time.

sum of the present value of (A) the payment on December 15, 2025 of principal of the Notes to be redeemed and (B) the payment of the remaining scheduled payments through December 15, 2025 of interest on the Notes to be redeemed
(excluding accrued and unpaid interest to 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 40 basis points plus, in each of the above cases, accrued and unpaid interest, if any, to such
Redemption Date.

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

by the Issuer. 
 “Reference Treasury Dealer Quotations means, with respect to each Reference Treasury Dealer and any Redemption Date,

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 Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to

Indenture and their consequences. Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in
exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note.
