the Notes shall no longer be represented by Global Securities and shall inform such 

  
 12 

 
Depositary of such determination and participants in such Depositary elect to withdraw their beneficial interests in the Notes from such Depositary, following notification by the Depositary of
their right to do so, or (C) such exchange is made upon request by or on behalf of the Depositary in accordance with customary procedures, following the request of a Holder seeking to exercise or enforce its rights under the Notes during the
continuance of an Event of Default. 
 (c) Subject to clause (b) above, any exchange of a Global Security for other Notes may be made in
whole or in part, and all Notes issued in exchange for a Global Security or any portion thereof shall be registered in such names as the Depositary for such Global Security shall direct in writing to the Trustee. 

(d) Every Note authenticated and delivered upon registration of transfer of, or in exchange for or in lieu of, a Global Security or any
portion thereof shall be authenticated and delivered in the form of, and shall be, a Global Security, unless such Note is registered in the name of a Person other than the Depositary for such Global Security or a nominee thereof. 

(e) Subject to the provisions of clause (g) below, the registered Holder may grant proxies and otherwise authorize any Person, including Agent
Members (as defined below in clause (g)) and Persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under this Indenture or the Notes. 

(f) In the event of the occurrence of any of the events specified in clause (b) above, the Company will promptly make available to the Trustee
a reasonable supply of certificated Notes in definitive, fully registered form, without interest coupons. 
 (g) Neither any members
of, or participants in, the Depositary (collectively, the “Agent Members”) nor any other Persons on whose behalf Agent Members may act shall have any rights under this Indenture with respect to any Global Security registered in the
name of the Depositary or any nominee thereof, or under any such Global Security, and the Depositary or such nominee, as the case may be, may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner
and holder of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company or the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy
or other authorization furnished by the Depositary or such nominee, as the case may be, or impair, as between the Depositary, its Agent Members and any other Person on whose behalf an Agent Member may act, the operation of customary practices of
such Persons governing the exercise of the rights of a Holder of any Note. 

  
 13 

 Section 3.04. Additional Notes. The Company may, from time to time,
subject to compliance with any other applicable provisions of this Indenture, without notice to or consent of the Holders of the Notes, create and issue pursuant to this Indenture additional Notes (“Additional Notes”)
having terms and conditions set forth in Exhibit A-1 or Exhibit A-2, as applicable, identical to those of the other Notes of such series, except that Additional Notes of a series: 

(i) may have a different issue date from other Outstanding Notes; 

(ii) may have a different issue price from other Outstanding Notes of such series; and 

(iii) may have a different amount of interest payable on the first Interest Payment Date after issuance than is payable on
other Outstanding Notes of such series; 
 provided that if such Additional Notes are not fungible with the applicable series of Initial Notes for
U.S. federal income tax purposes, such Additional Notes will have a separate CUSIP number. 
 ARTICLE 4 

REDEMPTION OF SECURITIES 

Section 4.01. Optional Redemption. (a) Subject to Section 1.02 hereof, the provisions of Article 11 of the
Base Indenture, as supplemented by the provisions of this Third Supplemental Indenture, shall apply to the Notes.  
 (b) At any time
before May 15, 2020, in the case of the 2020 Notes, and before March 15, 2025, in the case of the 2025 Notes, Notes of such series shall be redeemable, as a whole or in part, at the Company’s option, at a Redemption Price equal to the
greater of (i) 100% of the aggregate principal amount of the Notes to be redeemed or (ii) the sum of the present values of the Remaining Scheduled Payments, discounted 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 30 basis points, in the case of the 2020 Notes, and 37.5 basis points, in the case of the 2025 Notes, plus, in the case
of each of clause (i) or (ii), accrued and unpaid interest thereon to, but not including, the Redemption Date for such Notes. 
 (c) At
any time on or after May 15, 2020, in the case of the 2020 Notes (one month prior to the maturity date of the 2020 Notes), or on or after March 15, 2025, in the case of the 2025 Notes (three months prior to the maturity date of the 2025
Notes), Notes of such series shall be redeemable, as a whole or in part, at the Company’s election, at a Redemption Price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest thereon to, but not
including, the Redemption Date for such Notes. 

  
 14 

 (d) On and after the Redemption Date for a series of Notes, interest will cease to accrue
on such Notes or any portion thereof called for redemption, unless the Company defaults in the payment of the Redemption Price and accrued interest, if any. On or before the Redemption Date for the Notes, the Company shall deposit with the Trustee
or a Paying Agent, funds sufficient to pay the Redemption Price of the Notes to be redeemed on the Redemption Date, and (except if the Redemption Date shall be an Interest Payment Date) accrued interest, if any. If less than all of the Notes are to
be redeemed, the Notes of a series to be redeemed shall be selected in accordance with the procedures of the Depositary; provided, however that in no event, shall Notes of a principal amount of $2,000 or less be redeemed in part. 

(e) Notice of any redemption shall be electronically delivered or mailed at least 30 days but not more than 60 days before the
Redemption Date to each Holder of the Notes to be redeemed. Such notice shall state the Redemption Price (if known) or the formula pursuant to which the Redemption Price is to be determined if the Redemption Price cannot be determined at the time
the notice is given. If the Redemption Price cannot be determined at the time such notice is to be given, the actual Redemption Price, calculated as described above in clause (b) or (c), as applicable, shall be set forth in an Officers’
Certificate delivered to the Trustee no later than two Business Days prior to the Redemption Date. Notice of redemption having been given as provided in the Indenture, the Notes called for redemption shall become due and payable on the Redemption
Date and at the applicable Redemption Price, plus accrued and unpaid interest, if any, to, but not including, the Redemption Date. 

Section 4.02. Repurchase of Notes Upon a Change of Control. (a) If a Change of Control Repurchase Event occurs
with respect to a series of Notes, unless the Company shall have exercised its option to redeem such Notes as described in Section 4.01 of this Third Supplemental Indenture, the Company shall be required to make an offer (the “Change
of Control Offer”) to each Holder of applicable Notes to repurchase all or any part (equal to $2,000 or any multiple of $1,000 in excess thereof) of that Holder’s Notes of such series on the terms set forth in this Section 4.02
and in the Notes. In the Change of Control Offer, the Company shall be required to offer payment in cash equal to 101% of the aggregate principal amount of Notes repurchased, plus accrued and unpaid interest, if any, on the Notes repurchased up to,
but not including, the date of repurchase. Within 30 days following any Change of Control Repurchase Event with respect to a series of Notes or, at the option of the Company, prior to any Change of Control, but after the public announcement of
the transaction that constitutes or may constitute the Change of Control, the Company shall electronically deliver or mail a notice to Holders of Notes, with a copy to the  

  
 15 

 
Trustee, describing the transaction that constitutes or may constitute the Change of Control Repurchase Event and offering to repurchase such Notes on the date specified in the notice, which
date shall be no earlier than 30 days and no later than 60 days from the date such notice is electronically delivered or mailed (the “Change of Control Payment Date”). The notice shall, if electronically delivered or
mailed prior to the date of consummation of the Change of Control, state that the offer to purchase is conditioned on the Change of Control Repurchase Event occurring on or prior to the Change of Control Payment Date.  

(b) On the Change of Control Payment Date, the Company shall, to the extent lawful: 

(i) accept for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer; 

(ii) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions of
Notes properly tendered; and 
 (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 or portions of Notes being repurchased. 
 (c) The Paying
Agent will promptly deliver to each Holder of Notes properly tendered the payment for the Notes, and the Trustee will promptly authenticate and deliver (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. 
 (d) Notwithstanding the foregoing, the Company will not be required to make an offer to
repurchase Notes upon a Change of Control Repurchase Event, if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Company and such third party purchases all Notes
properly tendered and not withdrawn under its offer. 
 (e) If Holders of not less than 95% in aggregate principal amount of the applicable
series of Outstanding Notes validly tender and do not withdraw such Notes in an offer to repurchase the applicable Notes upon a Change of Control Repurchase Event and the Company, or any third party making an offer to repurchase such Notes upon a
Change of Control Repurchase Event in lieu of the Company pursuant to Section 4.02(d), purchases all Notes validly tendered and not withdrawn by such Holders, the Company shall have the right, upon not less than 30 nor more than 60 days’ prior
notice, given not more than 30 days following the Change of Control Payment Date, to redeem all Notes that remain Outstanding following such purchase at a Redemption Price in cash equal to 101% of the principal amount thereof, plus accrued and
unpaid interest, if any, to the Redemption Date. 

  
 16 

 (f) The Company shall comply, to the extent applicable, with the requirements of
Section 14e-1 of the Exchange Act and any other securities laws or regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of a series of Notes as a result of Change of Control Repurchase
Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control Repurchase Event provisions of a series of Notes, the Company will comply with the applicable securities laws and regulations and
shall not be deemed to have breached its obligations under the Change of Control Repurchase Event provisions of a series of Notes by virtue of such conflict. 

ARTICLE 5

(b) The foregoing restrictions shall not apply, however, to: 

(1) Liens on Property or Indebtedness existing with respect to any Person at the time such Person becomes a Subsidiary of the Company or a
Subsidiary of any Subsidiary of the Company, provided that such Lien was not incurred in anticipation of such Person becoming a Subsidiary;

Subsidiary of the Company of such Property or Indebtedness (which may include Property previously leased by the Company or any of its Subsidiaries and leasehold interests on such Property, provided that the lease terminates prior to or upon the
acquisition) or Liens on Property or Indebtedness to secure the payment of all or any part of the purchase price of such Property or Indebtedness, or Liens on Property or Indebtedness to secure any Indebtedness incurred prior to, at the time of, or

overdue by more than 60 calendar days or being contested in good faith by appropriate proceedings or other Liens arising out of judgments or awards against such Person with respect to which such Person shall then be proceeding with an appeal or
other proceedings for review and Liens arising solely by virtue of any statutory or common law provision relating to banker’s Liens, rights of set-off or similar rights and remedies as to deposit accounts or other funds maintained with a
creditor depository institution; 
 (9) Liens for taxes, assessments or other governmental charges or levies on Property not yet due or
payable or subject to penalties for non-payment or which are being contested in good faith by appropriate proceedings;

 (11) Permitted Liens; or 

  
 18 

 (12) any extensions, renewals or replacements of any Lien referred to in clauses (1) through
(11) without increase of the principal of the Indebtedness secured by such Lien (except to the extent of any fees or other costs associated with any such extension, renewal or replacement); provided, however, that any Liens permitted by any of
clauses (1) through (11) shall not extend to or cover any Property of the Company or any of its Subsidiaries, as the case may be, other than the Property specified in such clauses and improvements to such Property. 

(c) Notwithstanding the restrictions set forth in Section 5.01(a), the Company and its wholly owned U.S. Subsidiaries may incur
Indebtedness secured by Liens which would otherwise be subject to the foregoing restrictions without equally and ratably securing the Notes; provided that, after giving effect to such Indebtedness, the aggregate amount of all Indebtedness
secured by Liens (not including Liens permitted under clauses (1) through (12) of Section 5.01(b)), together with all Attributable Debt outstanding pursuant to Section 5.02(b), does not exceed 15% of Consolidated Total Assets calculated as
of the date of the creation or incurrence of the Lien. The Company and its wholly owned U.S. Subsidiaries may also, without equally and ratably securing the Notes, create or incur Liens that renew, substitute or replace (including successive
renewals, substitutions or replacements), in whole or in part, any Lien permitted pursuant to the preceding sentence. 

Section 5.02. Limitation on Sale and Leaseback Transactions. (a) The Company will not, nor will it permit any

Property to the purchase of other Property or assets used or useful in its business or to the retirement of long-term Indebtedness within 12 months before or after the effective date of any such sale and leaseback transaction, provided that,
in lieu of applying such amount to the retirement of long-term Indebtedness, the Company may deliver debt securities (which may include the Notes) to the applicable Trustee for cancellation, such debt securities to be credited at the cost thereof to
it. 
 (b) Notwithstanding the restrictions set forth in Section 5.02(a), the Company and its wholly owned U.S. Subsidiaries may enter into
any sale and leaseback transaction which would otherwise be subject to the foregoing restrictions, if after giving effect thereto the aggregate amount of all Attributable Debt with respect to such transactions (not including Attributable Debt
permitted under clauses (1) through (6) of Section 5.02(a)), together with all Indebtedness outstanding pursuant to Section 5.01(c), does not exceed 15% of Consolidated Total Assets calculated as of the closing date of the sale and
leaseback transaction.

the Base Indenture shall not apply to the Notes, and the following shall apply in lieu thereof. The Company shall not consolidate with or merge into any other Person or sell, convey, transfer, lease or otherwise dispose of all or substantially all
of its properties and assets to any Person, unless:

consolidation or merger, or which received the transfer of or leases the assets of the Company shall be a corporation organized and validly existing under the laws of the United States of America, any State thereof or the District of Columbia and
shall expressly assume, by an indenture supplemental to the Indenture, executed and delivered to the Trustee, in form satisfactory to the Trustee, the due and punctual payment of the principal of and premium (if any) and interest on all the Notes

immediately after giving effect to such transaction, no Event of Default shall have occurred and be continuing; and 
 (c) the Company or
the continuing entity has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, subject to customary qualifications and exceptions, each stating that such consolidation, merger, conveyance, transfer or lease and, if a
supplemental indenture is required in connection with such transaction, such supplemental indenture complies with this Article and that all conditions precedent herein provided for relating to such transaction have been complied with and such
supplemental indenture constitutes the legal, valid and binding obligation of the Company enforceable against the Company in accordance with its terms. 

  
 20 

 Section 5.04. Events of Default. Section 5.1 of the Base Indenture
shall not apply to the Notes. Each of the following events shall constitute an “Event of Default” with respect to a series of Notes: 

(a) default in the payment of the principal of or premium (if any) on any Note of such series when due and payable at its Stated Maturity, upon
optional redemption, acceleration or otherwise; 
 (b) default in the payment of any interest upon any Note of such series when it becomes

continuance of this failure to pay or (ii) a default on any indebtedness of the Company (other than indebtedness owing to any of its Subsidiaries), which default results in the acceleration of such indebtedness in an amount in excess of
$100,000,000 without such indebtedness having been discharged or the acceleration having been cured, waived, rescinded or annulled, in the case of clause (i) or (ii) above, for a period of 30 days after written notice thereof to the
Company by the Trustee or to the Company and the Trustee by the Holders of not less than 25% in principal amount of Outstanding Notes of such series (including any Additional Notes); provided, however, that if any failure, default or
acceleration referred to in clause (i) or (ii) above ceases or is cured, waived, rescinded or annulled, then the Event of Default will be deemed cured; 

  
 21 

 (f) the entry by a court having jurisdiction in the premises of (i) a decree or order for
relief in respect of the Company in an involuntary case or proceeding under any applicable Federal or State bankruptcy, insolvency, reorganization or other similar law or (ii) a decree or order adjudging the Company a bankrupt or insolvent, or
approving as properly filed a petition seeking reorganization, arrangement, adjustment or composition of or in respect of the Company under any applicable Federal or State law, or appointing a custodian, receiver, liquidator, assignee, trustee,
sequestrator or other similar official of the Company or of any substantial part of its 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; and 
 (g) the commencement by the Company of a voluntary case or proceeding
under any applicable Federal or State bankruptcy, insolvency, reorganization or other similar 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

receiver, liquidator, assignee, trustee, sequestrator or other similar official of the Company or 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 the Company in furtherance of any such action. 

Section 5.05. Acceleration Of Maturity; Rescission And Annulment. Section 5.2 of the Base Indenture shall not apply to
the Notes, and the following shall apply in lieu thereof. If an Event of Default occurs and is continuing with respect to a series of Notes, then and in every such case except as provided below, the Trustee or the Holders of not less than 25% in
aggregate principal amount of the Outstanding Notes of such series may declare the principal amount of all such Notes, plus accrued and unpaid interest, if any, to be due and payable immediately, by a notice in writing to the Company (and to the
Trustee if given by Holders), and upon any such declaration such principal amount shall become immediately due and payable. However, upon an Event of Default arising out of Section 5.04(f) or Section 5.04(g), the principal amount of all Outstanding
Notes, plus accrued and unpaid interest to the acceleration date, shall be due and payable immediately without notice from or other act on the part of the Trustee or any Holder. 

  
 22 

 At any time after such a declaration of acceleration with respect to Notes of a series has been
made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Indenture provided, the Holders of a majority in aggregate principal amount of the Outstanding Notes of such series, by written
notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if all Events of Default, other than the non-payment of the principal and interest, if any, of Notes which have become due solely by such declaration
of acceleration, have been cured or waived as provided in Section 5.13 of the Base Indenture. No such rescission shall affect any subsequent default or impair any right consequent thereon. 

In case the Trustee shall have proceeded to enforce any right under the Indenture and such proceedings shall have been discontinued or been
abandoned because of such rescission or annulment or for any other reason or shall have been determined adversely to the Trustee, then and in every such case the Company and the Trustee shall be restored respectively to their several positions and
rights hereunder, and all rights, remedies and powers of the Company and the Trustee shall continue as though no such proceedings had been taken. 

Section 5.06. References In Base Indenture. References to “Section 5.1(4),” “Section 5.1(5)” and
“Section 5.1(6)” in the Base Indenture shall be deemed to refer to Section 5.04(c), Section 5.04(f) and Section 5.04(g) of this Third Supplemental Indenture, respectively. 

Section 5.07. Waiver Of Certain Covenants. Section 10.8 of the Base Indenture shall not apply to any covenant
contained in this Third Supplemental Indenture. 
 Section 5.08. Maintenance of Office or Agency. In
accordance with Section 10.2 of the Base Indenture, the Company will maintain an office or agency where the Notes may be surrendered for registration of transfer or exchange or for presentation for payment, redemptions or repurchase and where
notices and demands to or upon the Company in respect of the Notes and this Indenture may be served. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency not designated
or appointed by the Trustee. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or
served at the Corporate Trust Office or the office or agency of the Trustee.

Section 6.01. Notice Of Defaults. The first two paragraphs of Section 6.2 of the Base Indenture shall not apply to the
Notes and the following shall apply in lieu thereof. 
 If a default occurs hereunder with respect to Notes of a series, the Trustee shall
give the Holders of Notes of such series notice of all defaults known to the Trustee which have occurred with respect to such series of Notes, such notice to be transmitted within 45 days after the occurrence thereof, unless such defaults shall have
been cured before the giving of such notice; provided, however, that except in the case of a default in the payment of principal or Redemption Price of (or premium, if any) or interest on any Notes of such series, the Trustee shall be protected in
withholding such notice if and so long as a trust committee of directors and/or Responsible Officers of the Trustee in good faith determine that the withholding of such notice is in the interests of the Holders of Notes of such series. For the
purpose of this Section 6.01, 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 Notes of such series. 

Except with respect to Section 10.1 of the Base Indenture, the Trustee shall have no duty to inquire as to the performance of the Company
with respect to the covenants contained in Article 10 of the Base Indenture or Article 5 hereof. In addition, the Trustee shall not be deemed to have knowledge of an Event of Default except (i) any default or Event of Default occurring
pursuant to Section 5.04(a) or Section 5.04(b) hereof (defaults in payments on the Notes) or (ii) any default or Event of Default of which a Responsible Officer of the Trustee shall have received written notification at the Corporate Trust
Office or obtained actual knowledge.

 (REVERSE OF NOTE) 

JUNIPER NETWORKS, INC. 
 3.300%
Senior Notes due 2020 
 1. Interest. 

Juniper Networks, Inc. (the “Issuer”) promises to pay interest on the principal amount of this Note at the rate per annum
described above. Cash interest on the Notes will accrue from the most recent date to which interest has been paid; or, if no interest has been paid, from March 4, 2015. Interest on this Note will be paid to but excluding the relevant Interest
Payment Date or on such earlier date as the principal amount shall become due in accordance with the provisions hereof. The Issuer will pay interest semi-annually in arrears on each Interest Payment Date, beginning on June 15, 2015, and on the
Stated Maturity. If any Interest Payment Date, Stated Maturity or other payment date with respect to the Notes is not a Business Day, the required payment of principal, premium, if any, or interest will be due on the next succeeding Business Day as
if made on the date that such payment was due, and no interest will accrue on that payment for the period from and after that Interest Payment Date, Stated Maturity or other payment date, as the case may be, to the date of that payment on the next
succeeding Business Day. Interest will be computed on the basis of a 360-day year consisting of twelve 30-day months. 
 The Issuer shall
pay interest on overdue principal from time to time on demand at the rate borne by the Notes and at the same rate on overdue installments of interest (without regard to any applicable grace periods) to the extent lawful from the dates such amounts
are due until such amounts are paid or made available for payment. 
 2. Paying Agent. 

Initially, The Bank of New York Mellon Trust Company, N.A. (the “Trustee”) will act as paying agent. The Issuer may
change any paying agent without notice to the Holders. 
 3. Indenture; Defined Terms. 

This Note is one of the 3.300% Senior Notes due 2020 (the “Notes”) issued under the Indenture dated as of March 3, 2011
(as amended, modified or supplemented from time to time in accordance therewith, the “Base Indenture” and, as amended, modified and supplemented by the Third Supplemental Indenture dated as of March 4, 2015, the
“Indenture”) by and between the Issuer and the Trustee, as trustee. This Note is a “Security” and the Notes are “Securities” under the Indenture. 

 For purposes of this Note, unless otherwise defined herein, capitalized terms herein are
used as defined in the Indenture. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. Sections 77aaa-77bbbb) (the “TIA”) as in
effect on the date on which the Indenture was qualified under the TIA. Notwithstanding anything to the contrary herein, the Notes are subject to all such terms, and holders of Notes are referred to the Indenture and the TIA for a statement of them.
To the extent the terms of the Indenture and this Note are inconsistent, the terms of the Indenture shall govern. 
 4.
Denominations; Transfer; Exchange. 
 The Notes are in registered form, without coupons, in denominations of $2,000 and multiples of $1,000
thereafter. A Holder shall register the transfer or exchange of Notes in accordance with the Indenture. The Issuer may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay certain transfer taxes
or similar governmental charges payable in connection therewith as permitted by the Indenture. The Issuer need not issue, authenticate, register the transfer of or exchange any Notes or portions thereof for a period of fifteen (15) days before
the mailing of a notice of redemption, nor need the Issuer register the transfer or exchange of any Note selected for redemption in whole or in part. 

5. Amendment; Modification; Waiver. 

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 rights of the Holders of the Securities of each series affected under the Indenture at any time by the Issuer and the Trustee with the consent of the Holders of not less than a majority in principal amount of the Securities of
each series at the time Outstanding affected thereby. The Indenture contains provisions permitting the Holders of not less than a majority in principal amount of the Securities of a series at the time Outstanding with respect to which a default
under the Indenture shall have occurred and be continuing, on behalf of the Holders of all Securities of such series, to waive, with certain exceptions, such past default with respect to the such series and its consequences. The Indenture also
permits the Holders of not less than a majority in principal amount of the Securities of a 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. 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 Security issued upon the registration of transfer hereof or in exchange therefor or
in lieu hereof, whether or not notation of such consent or waiver is made upon this Note. Without notice to or consent of any Holder, the Indenture also permits the 

 
amendment or supplement thereof to, among other things, cure any ambiguity, defect or inconsistency or comply with any requirements of the commission in connection with qualifications of the
Indenture under the TIA, or make any other change that does not adversely affect the rights of Holders. 
 6. Optional Redemption. 

The Issuer may redeem the Notes in whole or in part, at its option, at any time or from time to time prior to maturity on at least 30
days, but not more than 60 days, prior notice electronically delivered or mailed to the registered address of each Holder of the Notes (the “Redemption Date”) pursuant to the following terms:  

At any time before May 15, 2020, the redemption price will be equal to the greater of: 

(i) 100% of the aggregate principal amount of the Notes to be redeemed; or 

(ii) the sum of the present values of the remaining scheduled payments of the principal thereof and interest thereon that would be due after
the related Redemption Date but for such redemption, exclusive of interest accrued and unpaid to, but not including, the Redemption Date if such Redemption Date is not an Interest Payment Date, discounted to the Redemption Date on a semi-annual
basis (assuming a 360-day year consisting of twelve 30-day months), using a rate equal to the Treasury Rate plus 30 basis points (such sum to be calculated as set forth in the Indenture), 

plus, in the case of (i) or (ii), accrued interest thereon to, but not including, the Redemption Date. 

At any time on or after May 15, 2020, the Issuer may redeem the Notes, in whole or in part, at a redemption price equal to 100% of the
principal amount of the notes, plus accrued interest thereon to, but not including, the Redemption Date. 
 Notwithstanding the foregoing,
installments of interest on Notes that are due and payable on Interest Payment Dates falling on or prior to a Redemption Date will be payable on the Interest Payment Date to the registered Holders as of the close of business on the relevant record
date according to the Notes and the Indenture. 
 On and after the Redemption Date for the Notes, interest will cease to accrue on the Notes
or any portion thereof called for redemption, unless the Issuer defaults in the payment of the Redemption Price and accrued interest, if any. On or before the Redemption Date for the Notes, the Issuer shall deposit with the Trustee or a Paying
Agent, funds sufficient to pay the Redemption Price of the 

 
Notes to be redeemed on the Redemption Date, and (except if the Redemption Date shall be an Interest Payment Date) accrued interest, if any. If less than all of the Notes are to be redeemed, the
Notes to be redeemed shall be selected in accordance with the procedures of the Depositary; provided, however that in no event, shall Notes of a principal amount of $2,000 or less be redeemed in part. 

Notice of any redemption shall be electronically delivered or mailed at least 30 days but not more than 60 days before the
Redemption Date to each Holder of the Notes to be redeemed. Such notice shall state the Redemption Price (if known) or the formula pursuant to which the Redemption Price is to be determined if the Redemption Price cannot be determined at the time
the notice is given. If the Redemption Price cannot be determined at the time such notice is to be given, the actual Redemption Price, calculated as set forth in the Indenture, shall be set forth in an Officers’ Certificate of the Issuer
delivered to the Trustee no later than two Business Days prior to the Redemption Date. Notice of redemption having been given as provided in the Indenture, the Notes called for redemption shall become due and payable on the Redemption Date and at
the applicable Redemption Price, plus accrued and unpaid interest, if any, to, but not including, the Redemption Date. 
 7. Offer to
Repurchase Upon Change of Control Repurchase Event 
 Upon the occurrence of a Change of Control Repurchase Event with respect to the Notes,
unless the Issuer shall have exercised its right pursuant to Section 6 hereof to redeem the Notes, the Issuer shall be required to make an offer (the “Change of Control Offer”) to each Holder of such Notes to repurchase all or
any part (equal to $2,000 or any multiple of $1,000 in excess thereof) of that Holder’s Notes on the terms set forth in the Third Supplemental Indenture and in the Notes. In the Change of Control Offer, the Issuer shall be required to offer
payment in cash equal to 101% of the aggregate principal amount of Notes repurchased, plus accrued and unpaid interest, if any, on the Notes repurchased up to, but not including, the date of repurchase. 

Within 30 days following any Change of Control Repurchase Event with respect to the Notes or, at the option of the Issuer, prior to any
Change of Control, but after the public announcement of the transaction that constitutes or may constitute the Change of Control, the Issuer shall electronically deliver or mail a notice to Holders of Notes describing the transaction that
constitutes or may constitute the Change of Control Repurchase Event and offering to repurchase the Notes on the date specified in the notice, which date shall be no earlier than 30 days and no later than 60 days from the date such notice
is electronically delivered or mailed (the “Change of Control Payment Date”). The notice shall, if electronically delivered or mailed prior to the date of consummation of the Change of Control, state that the offer to purchase is
conditioned on the Change of Control Repurchase Event occurring on or prior to the Change of Control Payment Date. 

 On the Change of Control Payment Date, the Issuer shall, to the extent lawful: 

(i) accept for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer; 

(ii) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions of
Notes properly tendered; and 
 (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 or portions of Notes being purchased. 
 If Holders of
not less than 95% in aggregate principal amount of the Outstanding Notes validly tender and do not withdraw such Notes in an offer to repurchase the Notes upon a Change of Control Repurchase Event and the Issuer, or any third party making an offer
to repurchase the Notes upon a Change of Control Repurchase Event in lieu of the Company, purchases all Notes validly tendered and not withdrawn by such Holders, the Issuer shall have the right, upon not less than 30 nor more than 60 days’
prior notice, given not more than 30 days following the Change of Control Payment Date, to redeem all Notes that remain Outstanding following such purchase at a Redemption Price in cash equal to 101% of the principal amount thereof, plus accrued and
unpaid interest, if any, to the Redemption Date. 
 The Issuer shall comply, to the extent applicable, with the requirements of
Section 14e-1 of the Exchange Act and any other securities laws or regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of Notes as a result of Change of Control Repurchase Event. To
the extent that the provisions of any securities laws or regulations conflict with the Change of Control Repurchase Event provisions of the Notes, the Issuer will comply with the applicable securities laws and regulations and shall not be deemed to
have breached its obligations under the Change of Control Repurchase Event provisions of the Notes by virtue of such conflict. 
 8.
Defaults and Remedies. 
 If an Event of Default with respect to the Notes occurs and is continuing, then in every such case the Trustee or
the Holders of not less than 25% in principal amount of the Outstanding Notes may declare the principal amount of all the Notes to be due and payable immediately, by a notice in writing to the Issuer (and to the Trustee if given by Holders), and
upon any such declaration such principal amount (or specified amount) shall become immediately due and payable. 

 The Indenture permits, subject to certain limitations therein provided, Holders of not less than
a majority in aggregate principal amount of the Outstanding Notes to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee, with respect to
the Notes. 
 9. Authentication. 

This Note shall not be valid until the Trustee manually signs the certificate of authentication on this Note. 

10. Abbreviations and Defined Terms. 

Customary abbreviations may be used in the name of a Holder of a Note or an assignee, such as: TEN COM (= tenants in common), TEN ENT
(= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act). 

11. CUSIP Numbers. 
 Pursuant to
a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Issuer has caused CUSIP numbers to be printed on the Notes as a convenience to the Holders of the Notes. No representation is made as to the accuracy of
such numbers as printed on the Notes and reliance may be placed only on the other identification numbers printed hereon.

 Notice of any redemption shall be electronically delivered or mailed at least
30 days but not more than 60 days before the Redemption Date to each Holder of the Notes to be redeemed. Such notice shall state the Redemption Price (if known) or the formula pursuant to which the Redemption Price is to be determined if
the Redemption Price cannot be determined at the time the notice is given. If the Redemption Price cannot be determined at the time such notice is to be given, the actual Redemption Price, calculated as set forth in the Indenture, shall be set forth
in an Officers’ Certificate of the Issuer delivered to the Trustee no later than two Business Days prior to the Redemption Date. Notice of redemption having been given as provided in the Indenture, the Notes called for redemption shall become
due and payable on the Redemption Date and at the applicable Redemption Price, plus accrued and unpaid interest, if any, to, but not including, the Redemption Date. 

7. Offer to Repurchase Upon Change of Control Repurchase Event 

Upon the occurrence of a Change of Control Repurchase Event with respect to the Notes, unless the Issuer shall have exercised its right
pursuant to Section 6 hereof to redeem the Notes, the Issuer shall be required to make an offer (the “Change of Control Offer”) to each Holder of such Notes to repurchase all or any part (equal to $2,000 or any multiple of
$1,000 in excess thereof) of that Holder’s Notes on the terms set forth in the Third Supplemental Indenture and in the Notes. In the Change of Control Offer, the Issuer shall be required to offer payment in cash equal to 101% of the aggregate
principal amount of Notes repurchased, plus accrued and unpaid interest, if any, on the Notes repurchased up to, but not including, the date of repurchase. 

Within 30 days following any Change of Control Repurchase Event with respect to the Notes or, at the option of the Issuer, prior to any
Change of Control, but after the public announcement of the transaction that constitutes or may constitute the Change of Control, the Issuer shall electronically deliver or mail a notice to Holders of Notes describing the transaction that
constitutes or may constitute the Change of Control Repurchase Event and offering to repurchase the Notes on the date specified in the notice, which date shall be no earlier than 30 days and no later than 60 days from the date such notice
is electronically delivered or mailed (the “Change of Control Payment Date”). The notice shall, if electronically delivered or mailed prior to the date of consummation of the Change of Control, state that the offer to purchase is
conditioned on the Change of Control Repurchase Event occurring on or prior to the Change of Control Payment Date. 

 On the Change of Control Payment Date, the Issuer shall, to the extent lawful: 

(iv) accept for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer; 

(v) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes
properly tendered; and 
 (vi) deliver or cause to be delivered to the Trustee the Notes properly accepted together with an
Officers’ Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased. 
 If Holders of not less
than 95% in aggregate principal amount of the Outstanding Notes validly tender and do not withdraw such Notes in an offer to repurchase the Notes upon a Change of Control Repurchase Event and the Issuer, or any third party making an offer to
repurchase the Notes upon a Change of Control Repurchase Event in lieu of the Company, purchases all Notes validly tendered and not withdrawn by such Holders, the Issuer shall have the right, upon not less than 30 nor more than 60 days’ prior
notice, given not more than 30 days following the Change of Control Payment Date, to redeem all Notes that remain Outstanding following such purchase at a Redemption Price in cash equal to 101% of the principal amount thereof, plus accrued and
unpaid interest, if any, to the Redemption Date. 
 The Issuer shall comply, to the extent applicable, with the requirements of
Section 14e-1 of the Exchange Act and any other securities laws or regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of Notes as a result of Change of Control Repurchase Event. To
the extent that the provisions of any securities laws or regulations conflict with the Change of Control Repurchase Event provisions of the Notes, the Issuer will comply with the applicable securities laws and regulations and shall not be deemed to
have breached its obligations under the Change of Control Repurchase Event provisions of the Notes by virtue of such conflict. 
 8.
Defaults and Remedies. 
 If an Event of Default with respect to the Notes occurs and is continuing, then in every such case the Trustee or
the Holders of not less than 25% in principal amount of the Outstanding Notes may declare the principal amount of all the Notes to be due and payable immediately, by a notice in writing to the Issuer (and to the Trustee if given by Holders), and
upon any such declaration such principal amount (or specified amount) shall become immediately due and payable. 

 The Indenture permits, subject to certain limitations therein provided, Holders of not less than
a majority in aggregate principal amount of the Outstanding Notes to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee, with respect to
the Notes. 
 9. Authentication. 

This Note shall not be valid until the Trustee manually signs the certificate of authentication on this Note. 

10. Abbreviations and Defined Terms. 

Customary abbreviations may be used in the name of a Holder of a Note or an assignee, such as: TEN COM (= tenants in common), TEN ENT
(= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act). 

11. CUSIP Numbers. 
 Pursuant to
a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Issuer has caused CUSIP numbers to be printed on the Notes as a convenience to the Holders of the Notes. No representation is made as to the accuracy of
such numbers as printed on the Notes and reliance may be placed only on the other identification numbers printed hereon. 
 12. Governing
Law. 
 The laws of the State of New York shall govern the Indenture and this Note thereof.
