in any other manner, all as determined by two Officers of the Company executing such Notes, as evidenced by their execution of such Notes. 

Notes issued in global form will be substantially in the form of Exhibit A hereto, including the Global Note Legend thereon and the
“Schedule of Exchanges of Interests in the Global Note” attached thereto. Notes issued in definitive form will be substantially in the form of Exhibit A hereto but without the Global Note Legend thereon and without the “Schedule of
Exchanges of Interests in the Global Note” attached thereto. Each Global Note will represent such of the outstanding Notes as will be specified therein and each shall provide that it represents the aggregate principal amount of

  
 -17- 

 
outstanding Notes from time to time endorsed thereon and that the aggregate principal amount of outstanding Notes represented thereby may from time to time be reduced or increased, as
appropriate, to reflect exchanges and redemptions. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the aggregate principal amount of outstanding Notes represented thereby will be made by the Trustee or the
Custodian, at the direction of the Trustee, in accordance with instructions given by the Holder thereof as required by Section 311 hereof. 

SECTION 202. Form of Trustee’s Certificate of Authentication. 

The Trustee shall, upon receipt of a Company Order, authenticate Notes for original issue that may be validly issued under this Supplemental
Indenture, including any Additional Notes. The aggregate principal amount of Notes outstanding at any time may not exceed the aggregate principal amount of Notes authorized for issuance by the Company pursuant to one or more Company Orders, except
as provided in Section 306 hereof. 
 The Trustee may appoint an authenticating agent acceptable to the Company to authenticate Notes.
An authenticating agent may authenticate Notes whenever the Trustee may do so. Each reference in this Supplemental Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as an
Agent to deal with Holders or an Affiliate of the Company. 
 Subject to Section 611, the Trustee’s certificate of authentication
shall be in substantially the following form:

 Article III of
the Base Indenture is hereby modified, amended, supplemented and deleted as it relates to the Notes except as described in, and to the extent of, this Article Three. 

SECTION 301. Title and Terms. 

The aggregate principal amount of Notes which may be authenticated and issued under this Supplemental Indenture is not limited;
provided, however, that any Additional Notes issued under this Supplemental Indenture are issued in accordance with Section 303 hereof, as part of the same series as the Notes. 

The Notes shall be known and designated as the “4.250% Senior Notes due 2026” of the Company. The Stated Maturity of the Notes shall
be June 15, 2026, and the Notes shall bear interest at the rate of 4.250% per annum from June 13, 2019, or from the most recent Interest Payment Date to which interest has been paid or duly provided for on the Notes. 

Interest on the Notes is payable on December 15, 2019 and semi-annually thereafter on June 15 and December 15 of each year and
at the applicable Stated Maturity, until the principal of such Note is paid or duly provided for and to the Person in whose name such Note (or any Predecessor Note), is registered at the close of business on June 1 and December 1
immediately preceding such Interest Payment Date (each, a “Regular Record Date”). 
 The principal of (and premium, if any) and
interest on the Notes shall be payable at the office or agency of the Company maintained for such purpose or, at the option of the Company, payment of interest may be made by check mailed to the Holders of the Notes at their respective addresses set
forth in the Note Register of Holders; provided that all payments of principal, premium, if any, and interest with respect to Notes represented by one or more Global Notes registered in the name of or held by the Depositary or its nominee
will be made by wire transfer of immediately available funds to the accounts specified by the Holder or Holders thereof. Until otherwise designated by the Company, the Company’s office or agency shall be the office of the trustee maintained for
such purpose. 
 Holders shall have the right to require the Company to purchase their Notes, in whole or in part, in the event of a Change
in Control pursuant to Section 1016. 
 The Notes shall be redeemable as provided in Article Eleven.

SECTION 302. Denominations. 

The Notes shall be issuable only in registered form without coupons and only in minimum denominations of $2,000 and any integral multiple of
$1,000 in excess thereof. 
 SECTION 303. Execution, Authentication, Delivery and Dating. 

The Notes shall be executed on behalf of the Company by any two Officers. The signature of any Officer on the Notes may be manual or facsimile
signatures of the present or any future such authorized officer and may be imprinted or otherwise reproduced on the Notes. 
 Notes bearing
the manual or facsimile signatures of individuals who were at any time the proper officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and
delivery of such Notes or did not hold such offices at the date of such Notes. 
 At any time and from time to time after the execution and
delivery of this Supplemental Indenture, the Company may deliver Notes executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Notes, and the Trustee in accordance with
such Company Order shall authenticate and deliver such Notes. Such Company Order shall identify the Notes to be authenticated, the date on which the original issue of the Notes is to be authenticated, the number of separate Note certificates, the
principal amount of such Notes to be authenticated, the registered holder of each of the said Notes, and delivery instructions. 
 On the
Issue Date, the Company shall deliver the Initial Notes in the aggregate principal amount of $650,000,000 executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Notes,
directing the Trustee to authenticate the Notes and certifying that all conditions precedent to the issuance of Notes contained herein have been fully complied with, and the Trustee in accordance with such Company Order shall authenticate and
deliver such Initial Notes. At any time and from time to time after the Issue Date, the Company may deliver Additional Notes executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery
of such Additional Notes, directing the Trustee to authenticate the Additional Notes and certifying that the issuance of such Additional Notes is in compliance with Article Ten hereof and that all other conditions precedent to the issuance of Notes
contained herein have been fully complied with, and the Trustee in accordance with such Company Order shall authenticate and deliver such Additional Notes; provided, however, that, notwithstanding anything to the contrary, no Opinion
of Counsel will be required in connection with the authentication of the Initial Notes. In each case, the Trustee shall receive an Officers’ Certificate and an Opinion of Counsel of the Company that it may reasonably require in connection with
such authentication of Notes. Such order shall specify the amount of Notes to be authenticated and the date on which the original issue of Notes is to be authenticated. 

Each Note shall be dated the date of its authentication. 

No Note shall be entitled to any benefit under this Supplemental Indenture or be valid or obligatory for any purpose unless there appears on
such Note a certificate of authentication substantially in the form provided for herein duly executed by the Trustee by manual signature of an authorized officer, and such certificate upon any Note shall be conclusive evidence, and the only
evidence, that such Note has been duly authenticated and delivered hereunder and is entitled to the benefits of this Supplemental Indenture. 

  
 -20- 

 In case the Company, pursuant to Article Eight, shall be amalgamated, consolidated or merged
with or into any other Person or shall convey, transfer, lease or otherwise dispose of its properties and assets substantially as an entirety to any Person, and the successor Person resulting from such amalgamation or consolidation, or surviving
such merger, or into which the Company shall have been merged, or the Person which shall have received a conveyance, transfer, lease or other disposition as aforesaid, shall have executed a supplemental indenture hereto with the Trustee pursuant to
Article Nine, any of the Notes authenticated or delivered prior to such consolidation, merger, conveyance, transfer, lease or other disposition may, from time to time, at the request of the successor Person, be exchanged for other Notes executed in
the name of the successor Person with such changes in phraseology and form as may be appropriate, but otherwise in substance of like tenor as the Notes surrendered for such exchange and of like principal amount; and the Trustee, upon Company Request
of the successor Person, shall authenticate and deliver Notes as specified in such request for the purpose of such exchange. If Notes shall at any time be authenticated and delivered in any new name of a successor Person pursuant to this Section in
exchange or substitution for or upon registration of transfer of any Notes, such successor Person, at the option of the Holders but without expense to them, shall provide for the exchange of all Notes at the time Outstanding for Notes authenticated
and delivered in such new name. 
 SECTION 304. Temporary Notes. 

In the event Definitive Notes are to be issued pursuant to the terms of this Supplemental Indenture, pending the preparation of Definitive
Notes, the Company may execute, and upon Company Order the Trustee shall authenticate and deliver, temporary Notes which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the
tenor of the Definitive Notes in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Notes may determine, as conclusively evidenced by their execution of
such Notes. 
 If temporary Notes are issued, the Company will cause Definitive Notes to be prepared without unreasonable delay. After the
preparation of Definitive Notes, the temporary Notes shall be exchangeable for Definitive Notes upon surrender of the temporary Notes at the office or agency of the Company designated for such purpose pursuant to Section 1002, without charge to
the Holder. Upon surrender for cancellation of any one or more temporary Notes, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a like principal amount of Definitive Notes of authorized denominations.
Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits under this Supplemental Indenture as Definitive Notes. 

SECTION 305. Registration, Paying Agent, Registration of Transfer and Exchange. 

The Company shall cause to be kept at the Corporate Trust Office of the Trustee a register (the register maintained in such office and in any
other office or agency designated pursuant to Section 1002 being herein sometimes referred to as the “Note Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration
of Notes and of transfers of Notes. The Note Register shall be in written form or any other form capable of being converted into written form within a reasonable time. At all reasonable times, the Note Register shall be open to inspection by the
Trustee. The Trustee is hereby initially appointed as note registrar (the “Note Registrar”) for the purpose of registering Notes and transfers of Notes as herein provided and as Paying Agent. The Company may appoint one or more co-registrars and one or more additional paying agents. 

  
 -21- 

 
The Company may change any Paying Agent or Registrar without prior notice to any Holder; provided, that the Company shall maintain one or more Paying Agents. The Company shall notify the
Trustee in writing of the name and address of any Agent not party to this Supplemental Indenture. If the Company fails to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such. The Company may act as Paying
Agent or Registrar. 
 The Company initially appoints DTC to act as Depositary with respect to the Global Notes. 

Upon surrender for registration of transfer of any Note at the office or agency of the Company designated pursuant to Section 1002, the
Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes of any authorized denomination or denominations of a like aggregate principal amount. 

At the option of the Holder, Notes may be exchanged for other Notes of any authorized denomination and of a like aggregate principal amount,
upon surrender of the Notes to be exchanged at such office or agency. Whenever any Notes are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Notes which the Holder making the exchange is
entitled to receive. 
 All Notes issued upon any registration of transfer or exchange of Notes shall be the valid obligations of the
Company, evidencing the same debt, and entitled to the same benefits under this Supplemental Indenture, as the Notes surrendered upon such registration of transfer or exchange. 

Every Note presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the Note Registrar)
be duly endorsed, or be accompanied by written instruments of transfer, in form satisfactory to the Company and the Note Registrar, duly executed by the Holder thereof or his attorney duly authorized in writing. 

No service charge shall be made for any registration of transfer or exchange or redemption of Notes, but the Company may require payment of a
sum sufficient to cover any taxes, fees or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Notes, other than exchanges pursuant to Sections 304, 906, 1016 or 1109 not involving any
transfer. 
 Neither the Registrar nor the Company shall be required to register the transfer of or exchange any Note selected for
redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part. 
 SECTION 306. Mutilated, Destroyed,
Lost and Stolen Notes. 
 If (i) any mutilated Note is surrendered to the Trustee, or (ii) the Company and the Trustee receive
evidence to their satisfaction of the destruction, loss or theft of any Note, and there is delivered to the Company and the Trustee such security or indemnity as may be required by them to protect the Trustee, any Agent and the Company from any
loss, then, in the absence of notice to the Company or the Trustee that such Note has been acquired by a bona fide purchaser, the Company shall execute and upon Company Order the Trustee shall authenticate and deliver, in exchange for any such
mutilated Note or in lieu of any such destroyed, lost or stolen Note, a new Note of like tenor and principal amount, bearing a number not contemporaneously outstanding. 

  
 -22- 

 In case any such mutilated, destroyed, lost or stolen Note has become or is about to become
due and payable, the Company in its discretion may, instead of issuing a new Note, pay such Note. 
 Upon the issuance of any new Note under
this Section, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith.

 Every new Note issued pursuant to this Section in lieu of any mutilated, destroyed, lost or stolen Note shall constitute an original
additional contractual obligation of the Company and shall be entitled to all benefits of this Supplemental Indenture equally and proportionately with any and all other Notes duly issued hereunder. 

The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the
replacement or payment of mutilated, destroyed, lost or stolen Notes. 
 SECTION 307. Payment of Interest; Interest Rights Preserved.

 Interest on any Note which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the
Person in whose name such Note (or one or more Predecessor Notes) is registered at the close of business on the Regular Record Date for such interest at the office or agency of the Company maintained for such purpose pursuant to Section 1002;
provided, however, that, subject to Section 301 hereof, each installment of interest may at the Company’s option be paid by (i) mailing a check for such interest, payable to or upon the written order of the Person
entitled thereto pursuant to Section 308, to the address of such Person as it appears in the Note Register or (ii) transfer to an account located in the United States maintained by the payee. 

Any interest on any Note which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date shall forthwith cease
to be payable to the Holder on the Regular Record Date by virtue of having been paid to such Holder, and such defaulted interest and (to the extent lawful) interest on such defaulted interest at the rate borne by the Notes (such defaulted interest
and interest thereon herein collectively called “Defaulted Interest”) may be paid by the Company, at its election in each case, as provided in clause (1) or (2) below: 

(1) The Company may elect to make payment of any Defaulted Interest on the Notes to the Persons in whose names such Notes (or
their respective Predecessor Notes) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the
amount of Defaulted Interest proposed to be paid on each Note and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of
such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted
Interest as in this clause provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not
less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date, and in the name and at the expense of the Company, shall cause notice of the
proposed payment of such Defaulted Interest and the Special Record 

  
 -23- 

 
Date therefor to be given in the manner provided for in Section 1305, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and
the Special Record Date therefor having been so given, such Defaulted Interest shall be paid to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at the close of business on such Special Record Date and
shall no longer be payable pursuant to the following clause (2). 
 (2) The Company may make payment of any Defaulted
Interest in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of
the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee. 
 Subject to the foregoing
provisions of this Section, each Note delivered under this Supplemental Indenture upon registration of transfer of or in exchange for or in lieu of any other Note shall carry the rights to interest accrued and unpaid, and to accrue, which were
carried by such other Note. 
 SECTION 308. Persons Deemed Owners. 

Prior to the due presentment of a Note for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may
treat the Person in whose name such Note is registered as the owner of such Note for the purpose of receiving payment of principal of (and premium, if any) and (subject to Sections 305 and 307) interest on such Note and for all other purposes
whatsoever, whether or not such Note be overdue, and none of the Company, the Trustee or any agent of the Company or the Trustee shall be affected by notice to the contrary. 

SECTION 309. Cancellation. 

All Notes surrendered for payment, redemption, registration of transfer or exchange shall, if surrendered to any Person other than the Trustee,
be delivered to the Trustee and shall be promptly cancelled by it. The Company may at any time deliver to the Trustee for cancellation any Notes previously authenticated and delivered hereunder. All Notes so delivered shall be promptly cancelled by
the Trustee. If the Company shall so acquire any of the Notes, however, such acquisition shall not operate as a redemption or satisfaction of the indebtedness represented by such Notes unless and until the same are surrendered to the Trustee for
cancellation. No Notes shall be authenticated in lieu of or in exchange for any Notes cancelled as provided in this Section, except as expressly permitted by this Supplemental Indenture. All cancelled Notes held by the Trustee shall be disposed of
by the Trustee in accordance with its customary procedures. Evidence of the destruction of all cancelled Notes shall upon the written request of the Company be delivered to the Company. 

SECTION 310. Computation of Interest. 

Interest on the Notes shall be computed on the basis of a 360-day year of twelve 30-day months. 
 SECTION 311. Book-Entry and Transfer Provisions. 

(a) Transfer and Exchange of Global Notes. A Global Note may not be transferred except as a whole by the Depositary to a nominee of the
Depositary, by a nominee of the Depositary to the Depositary or to another nominee of the Depositary, or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. All Global Notes will be exchanged by
the Company for Definitive Notes if:

or 
 (3) there has occurred and is continuing a Default or Event of Default with respect to the Notes. 

Upon the occurrence of either of the preceding events in (1) or (2) above, Definitive Notes shall be issued in such names as the
Depositary shall instruct the Trustee. Global Notes also may be exchanged or replaced, in whole or in part, as provided in Sections 304 and 306 hereof. Every Note authenticated and delivered in exchange for, or in lieu of, a Global Note or any
portion thereof, pursuant to this Section 312 or Sections 304 or 306 hereof, shall be authenticated and delivered in the form of, and shall be, a Global Note. A Global Note may not be exchanged for another Note other than as provided in this
Section 311(a), however, beneficial interests in a Global Note may be transferred and exchanged as provided in Section 311(b) or (c) hereof. 

(b) Transfer and Exchange of Beneficial Interests in the Global Notes. The transfer and exchange of beneficial interests in the Global
Notes will be effected through the Depositary, in accordance with the provisions of this Supplemental Indenture and the Applicable Procedures. None of the Company, the Trustee, Paying Agent, nor any agent of the Company shall have any responsibility
or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in a Global Note, or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.
Transfers of beneficial interests in the Global Notes also will require compliance with either subparagraph (1) or (2) below, as applicable, as well as one or more of the other following subparagraphs, as applicable: 

(1) Transfer of Beneficial Interests in the Same Global Note. Beneficial interests in any Global Note may be transferred

exchanges of beneficial interests that are not subject to Section 311(b)(1) above, the transferor of such beneficial interest must deliver to the Note Registrar either: 

(A) both: 

(x) a written order from a Participant or an Indirect Participant given to the Depositary in accordance with the Applicable
Procedures directing the Depositary to credit or cause to be credited a beneficial interest in another Global Note in an amount equal to the beneficial interest to be transferred or exchanged; and 

  
 -25- 

 (y) instructions given in accordance with the Applicable Procedures
containing information regarding the Participant account to be credited with such increase; or 
 (B) both: 

(x) a written order from a Participant or an Indirect Participant given to the Depositary in accordance with the Applicable
Procedures directing the Depositary to cause to be issued a Definitive Note in an amount equal to the beneficial interest to be transferred or exchanged; and 

(y) instructions given by the Depositary to the Note Registrar containing information regarding the Person in whose name such
Definitive Note shall be registered to effect the transfer or exchange referred to in (A) above. 
 Upon satisfaction of all of the
requirements for transfer or exchange of beneficial interests in Global Notes contained in this Supplemental Indenture and the Notes or otherwise applicable under the Securities Act, the Trustee shall adjust the principal amount of the relevant
Global Note(s) pursuant to Section 311(g) hereof. 
 (c) Transfer or Exchange of Beneficial Interests for Definitive Notes. If
any holder of a beneficial interest in a Global Note proposes to exchange such beneficial interest for a Definitive Note or to transfer such beneficial interest to a Person who takes delivery thereof in the form of a Definitive Note, then, upon
satisfaction of the conditions set forth in Section 311(b)(2) hereof, the Trustee will cause the aggregate principal amount of the applicable Global Note to be reduced accordingly pursuant to Section 311(g) hereof, and the Company will
execute and the Trustee will authenticate and deliver to the Person designated in the instructions a Definitive Note in the appropriate principal amount. Any Definitive Note issued in exchange for a beneficial interest pursuant to this
Section 311(c) will be registered in such name or names and in such authorized denomination or denominations as the holder of such beneficial interest requests through instructions to the Note Registrar from or through the Depositary and the
Participant or Indirect Participant. The Trustee will deliver such Definitive Notes to the Persons in whose names such Notes are so registered. 

(d) Transfer and Exchange of Definitive Notes for Beneficial Interests. A Holder of a Definitive Note may exchange such Note for a
beneficial interest in a Global Note or transfer such Definitive Note to a Person who takes delivery thereof in the form of a beneficial interest in a Global Note at any time. Upon receipt of a request for such an exchange or transfer, the Trustee
will cancel the applicable Definitive Note and increase or cause to be increased the aggregate principal amount of one of the Global Notes. 

If any such exchange or transfer from a Definitive Note to a beneficial interest in a Global Note is effected pursuant to this
Section 311(d) at a time when a Global Note has not yet been issued, the Company will issue and, upon receipt of a Company Order in accordance with Section 202 hereof, the Trustee will authenticate one or more Global Notes in an aggregate
principal amount equal to the principal amount of Definitive Notes so transferred. 
 (e) Transfer and Exchange of Definitive Notes for
Definitive Notes. Upon request by a Holder of Definitive Notes and such Holder’s compliance with the provisions of this Section 311(e), the Note Registrar will register the transfer or exchange of Definitive Notes. Prior to such
registration of transfer or exchange, the requesting Holder must present or surrender to the Note Registrar the Definitive Notes duly endorsed or accompanied by a written instruction of transfer in form satisfactory to the Note Registrar duly
executed by such Holder or by its attorney, duly authorized in writing. In addition, the requesting Holder must provide any additional certifications, documents and information, as applicable, required pursuant to the following provisions of this
Section 311(e).

 (f) [Reserved]. 

(g) Cancellation and/or Adjustment of Global Notes. At such time as all beneficial interests in a particular Global Note have been
exchanged for Definitive Notes or a particular Global Note has been redeemed, repurchased or canceled in whole and not in part, each such Global Note will be returned to or retained and canceled by the Trustee in accordance with Section 309
hereof. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note or for Definitive
Notes, the principal amount of Notes represented by such Global Note will be reduced accordingly and an endorsement will be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such reduction; and
if the beneficial interest is being exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note, such other Global Note will be increased accordingly and an endorsement will be
made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such increase. 
 (h) General

(5) Neither the Note Registrar nor the Company will be required: 

(A) to issue, to register the transfer of or to exchange any Notes during a period beginning at the opening of business 15 days

requirements hereof.

Depositary. 
 SECTION 312. CUSIP Numbers. 

The Company in issuing the Notes may use “CUSIP,” “ISIN” or other numbers (if then generally in use) in addition to serial
numbers, and, if so, the Trustee shall use such “CUSIP,” “ISIN” or other numbers in addition to serial numbers in notices of redemption, repurchase or other notices to Holders as a convenience to Holders; provided that any
such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of a redemption or repurchase and that reliance may be placed only on the serial or other
identification numbers printed on the Notes, and any such redemption or repurchase shall not be affected by any defect in or omission of such numbers. The Company will promptly notify the Trustee in writing of any change in the CUSIP, ISIN or other
numbers. 
 SECTION 313. Issuance of Additional Notes. 

The Company may issue from time to time, without notice to or consent of the Holders additional Notes having identical terms and conditions to
the Initial Notes, other than with respect to the date of issuance and issue price and first payment of interest (the “Additional Notes”). The Initial Notes and any Additional Notes subsequently issued shall be treated as a single class
for all purposes under this Supplemental Indenture. 
 With respect to any Additional Notes, the Company shall set forth in an
Officers’ Certificate pursuant to a resolution of the Board of Directors of the Company, copies of which shall be delivered to the Trustee, the following information: 

  
 -28- 

 (1) the aggregate principal amount of such Additional Notes to be
authenticated and delivered pursuant to this Supplemental Indenture; and

 ARTICLE FOUR 

SATISFACTION AND DISCHARGE

as described in, and to the extent of, this Article Four. 
 SECTION 401. Satisfaction and Discharge of Indenture. 

This Supplemental Indenture shall upon Company Request be discharged and will cease to be of further effect as to the Notes issued hereunder
(except as to surviving rights of registration of transfer or exchange of Notes expressly provided for herein or pursuant hereto) and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and
discharge of this Supplemental Indenture when: 
 (1) either 

(a) all Notes theretofore authenticated and delivered (other than (i) Notes which have been destroyed, lost or stolen and
which have been replaced or paid as provided in Section 306 and (ii) Notes for whose payment money has theretofore been deposited in trust with the Trustee or any Paying Agent or segregated and held in trust by the Company and thereafter
repaid to the Company or discharged from such trust, as provided in Section 1003) have been delivered to the Trustee for cancellation; or 

(b) all such Notes not theretofore delivered to the Trustee for cancellation 

(i) have become due and payable by reason of the making of a notice of redemption pursuant to Section 1106 or otherwise,
or 
 (ii) will become due and payable at their Stated Maturity within one year, or 

(iii) are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice
of redemption by the Trustee in the name, and at the expense, of the Company, 
 and the Company, in the case of (i), (ii) or
(iii) above, has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders (other than with respect to any amounts deposited by the Company in excess of the redemption price),
cash in U.S. dollars, Government Securities, or a combination thereof, in such amounts as will be sufficient without consideration of any reinvestment of interest to pay and discharge the entire indebtedness on such Notes not theretofore delivered
to the Trustee for cancellation, for principal (and premium, if any) and accrued interest to the Stated Maturity or the Redemption Date, as the case may be; provided, further, that with respect to any redemption pursuant to
Section 1101(b), the amount 

  
 -29- 

 
deposited shall be sufficient to the extent that an amount is deposited with the Trustee equal to the amount calculated under Section 1101(b) as of the date of the notice of redemption,
provided, further, that the Company shall deposit any deficit (any such amount, the “Applicable Premium Deficit”) with the Trustee on or prior to the Redemption Date and shall simultaneously deliver to the Trustee an
Officers’ Certificate which shall set forth the Applicable Premium Deficit and confirm that such Applicable Premium Deficit shall be applied toward such redemption. 

(2) no Default or Event of Default with respect to the Outstanding Notes (other than that resulting from borrowing funds to be
applied to make such deposit or the granting of Liens in connection therewith) shall have occurred and be continuing on the date of such deposit or shall occur as a result of such deposit and such deposit shall not result in a breach or violation
of, or constitute a default under, any other instrument to which the Company is a party or by which the Company is bound (other than an instrument to be terminated contemporaneously with or prior to the borrowing of funds to be applied to make such
deposit and the granting of Liens in connection therewith); 
 (3) the Company has paid or caused to be paid all sums payable
by it under this Supplemental Indenture with respect to the Notes; 
 (4) the Company has delivered irrevocable instructions
to the Trustee under this Supplemental Indenture to apply the deposited money toward the payment of such Notes at the Stated Maturity or the Redemption Date, as the case may be; and 

(5) the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all
conditions precedent herein to the satisfaction and discharge of this Supplemental Indenture have been complied with. 
 Notwithstanding the
satisfaction and discharge of this Supplemental Indenture, the obligations of the Company to the Trustee under Section 607, the obligations of the Company to any Authenticating Agent under Section 612 and, if money or Government Securities
shall have been deposited with the Trustee pursuant to subclause (b) of clause (1) of this Section, the obligations of the Trustee under Section 402 and the last paragraph of Section 1003 shall survive such satisfaction and
discharge. 
 SECTION 402. Application of Trust Money. 

Subject to the provisions of the last paragraph of Section 1003, all money or Government Securities deposited with the Trustee pursuant to
Section 401 shall be held in trust and applied by it, in accordance with the provisions of the Notes and this Supplemental Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying
Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal (and premium, if any) and interest for whose payment such money or Government Securities has been deposited with the Trustee; but such money or Government
Securities need not be segregated from other funds except to the extent required by law. 
 If the Trustee or Paying Agent is unable to
apply any money or Government Securities in accordance with Section 401 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such
application, the Company’s obligations under this Supplemental Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 401 until such time as the Trustee or Paying Agent

  
 -30- 

 
is permitted to apply all such money or Government Securities in accordance with Section 401; provided that if the Company has made any payment of principal of, premium, if any, or
interest on any Notes because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or Government Securities held by the Trustee or Paying Agent.

 ARTICLE FIVE

(1) default in payment when due and payable, upon redemption, acceleration or otherwise, of principal of, or premium, if any,

(4) default under any mortgage, indenture or instrument under which there is issued or by which there is secured or evidenced
any Indebtedness for money borrowed by the Company or any Significant Subsidiary or the payment of which is guaranteed by the Company or any Significant Subsidiary, other than Indebtedness owed to the Company or a Significant Subsidiary, whether
such Indebtedness or guarantee now exists or is created after the issuance of the Notes, if both 
 (A) such default either
(x) results from the failure to pay any such Indebtedness at its stated final maturity (after giving effect to any applicable grace periods) or (y) relates to an obligation other than the obligation to pay principal of any such
Indebtedness at its stated final maturity and results in the holder or holders of such Indebtedness causing such Indebtedness to become due prior to its stated maturity; and 

(B) the principal amount of such Indebtedness, together with the principal amount of any other such Indebtedness in default for
failure to pay principal at stated final maturity (after giving effect to any applicable grace periods), or the maturity of which has been so accelerated, aggregate to the greater of (i) $125.0 million and (ii) 1.75% of Total Assets or more at
any one time outstanding; 

  
 -31- 

 (5) failure by the Company or any Significant Subsidiary to pay final, non-appealable judgments aggregating in excess of the greater of (i) $125.0 million and (ii) 1.75% of Total Assets, which final judgments remain unpaid, undischarged and unstayed for a period of more than 60
days after such judgment becomes final, and in the event such judgment is covered by insurance, an enforcement proceeding has been commenced by any creditor upon such judgment or decree which is not promptly stayed; or 

(6) any of the following events with respect to the Company or any Significant Subsidiary: 

(A) the Company or any Significant Subsidiary pursuant to or within the meaning of any Bankruptcy Law

(ii) consents to the entry of an order for relief against it in an involuntary case; 

(iii) consents to the appointment of a custodian of it or for any substantial part of its property; 

(iv) takes any comparable action under any foreign laws relating to insolvency; or 

(B) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that: 

(i) is for relief against the Company or any Significant Subsidiary in an involuntary case; 

(ii) appoints a custodian of the Company or any Significant Subsidiary or for any substantial part of its property; or 

(iii) orders the winding up or liquidation of the Company or any Significant Subsidiary; 

(iv) and the order or decree remains undischarged, unstayed or unremedied and in effect for 60 consecutive days. 

SECTION 502. Acceleration of Maturity; Rescission and Annulment. 

If an Event of Default (other than an Event of Default specified in Section 501(6) above) with respect to the Notes occurs and is
continuing, then and in every such case the Trustee or the Holders of at least 25% in principal amount of the Outstanding Notes issued under the Indenture may declare the principal, premium, if any, interest and any other monetary obligations on all
the Outstanding Notes to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by Holders). 

Upon the effectiveness of such declaration, such principal and interest will be due and payable immediately. Notwithstanding the foregoing, if
an Event of Default specified in Section 501(6) above occurs and is continuing, then the principal amount of all Outstanding Notes shall ipso facto become and be immediately due and payable without any notice, declaration or other act on the
part of the Trustee or any Holder. 

  
 -32- 

 At any time after a declaration of acceleration has been made and before a judgment or
decree for payment of the money due has been obtained by the Trustee as hereinafter provided in this Article, the Holders of a majority in aggregate principal amount of the Outstanding Notes by written notice to the Company and the Trustee, may
rescind and annul such declaration and its consequences except a continuing Default or Event of Default in the payment of interest on, premium, if any, or the principal of any such Note held by a
non-consenting Holder. No such rescission shall affect any subsequent default or impair any right consequent thereon. 

Notwithstanding the preceding paragraph, in the event of any Event of Default specified in Section 501(4) above with respect to the
Notes, such Event of Default and all consequences thereof (excluding any resulting payment default, other than as a result of the acceleration of the Notes) shall be annulled, waived and rescinded, automatically and without any action by the Trustee
or the Holders, if within 20 days after such Event of Default arose, 
 (x) the Indebtedness or guarantee that is the basis
for such Event of Default has been discharged, or 
 (y) the holders thereof have rescinded or waived the acceleration,
notice or action (as the case may be) giving rise to such Event of Default, or 
 (z) if the default that is the basis for
such Event of Default has been cured. 
 SECTION 503. Collection of Indebtedness and Suits for Enforcement by Trustee. 

The Company covenants that if an Event of Default specified in Section 501(1) or 501(2) hereof occurs and is continuing with respect to
the Notes, the Company will, upon demand of the Trustee, pay to the Trustee for the benefit of the Holders of such Notes, the whole amount then due and payable on such Notes for principal (and premium, if any) and interest, and interest on any
overdue principal (and premium, if any) and, to the extent that payment of such interest shall be legally enforceable, upon any overdue installment of interest, at the rate borne by such Notes, and, in addition thereto, such further amount as shall
be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. 

If the Company fails to pay such amounts forthwith upon such demand, the Trustee, in its own name as trustee of an express trust, may
institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other obligor upon the Notes and collect the moneys
adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon such Notes, wherever situated. 

If an Event of Default occurs and is continuing with respect to the Notes, the Trustee may in its discretion proceed to protect and enforce
its rights and the rights of the Holders under the Indenture and the Note Guarantees by such appropriate judicial proceedings as the Trustee shall deem necessary to protect and enforce any such rights whether for the specific enforcement of any
covenant or agreement in the Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy. 

  
 -33- 

 SECTION 504. Trustee May File Proofs of Claim. 

In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company or any other obligor, upon the Notes or the property of the Company or of such other obligor or their creditors, the Trustee (irrespective of whether the principal of the Notes shall then be due and
payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the payment of overdue principal, premium, if any, or interest) shall be entitled and empowered, by
intervention in such proceeding or otherwise, 
 (i) to file and prove a claim for the whole amount of principal (and
premium, if any) and interest owing and unpaid in respect of the Notes and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders allowed in such judicial proceeding, and 

(ii) to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same;

 and any custodian, receiver, assignee, trustee, liquidator, sequestrator or similar official in any such judicial proceeding is hereby authorized by each
Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay the Trustee any amount due it for the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, and any other amounts due the Trustee hereunder. 
 Nothing herein contained shall be
deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder thereof, or to authorize the
Trustee to vote in respect of the claim of any Holder in any such proceeding. 
 SECTION 505. Trustee May Enforce Claims Without
Possession of Notes. 
 All rights of action and claims under the Indenture or the Notes may be prosecuted and enforced by the Trustee
without the possession of any of the Notes or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name and as trustee of an express trust, and any recovery of
judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders in respect of which such judgment has been
recovered. 
 SECTION 506. Application of Money Collected. 

Any money collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed by the Trustee
and, in case of the distribution of such money on account of principal (or premium, if any) or interest, upon presentation of the Notes and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid: 

FIRST: To the payment of all amounts due the Trustee (in its capacity as Trustee, Paying Agent and/or Note Registrar, as
applicable) under the Indenture; 

  
 -34- 

 SECOND: To the payment of the amounts then due and unpaid for
principal of (and premium, if any) and interest on the Notes in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Notes
for principal (and premium, if any) and interest, respectively; and 
 THIRD: The balance, if any, to the Company or
any other obligor on the Notes, as their interests may appear or as a court of competent jurisdiction may direct in writing; provided that all sums due and owing to the Holders and the Trustee have been paid in full as required by this
Supplemental Indenture. 
 SECTION 507. Limitation on Suits. 

No Holder of any Notes shall have any right to institute any proceeding, judicial or otherwise, with respect to the Indenture, or for the
appointment of a receiver or trustee, or for any other remedy hereunder, unless: 
 (1) such Holder has previously given
written notice to the Trustee of a continuing Event of Default; 
 (2) the Holders of not less than 25% in principal amount
of the Outstanding Notes shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder; 

(3) such Holder or Holders have offered to the Trustee indemnity reasonably satisfactory to it against the costs, expenses and
liabilities to be incurred in compliance with such request; 
 (4) the Trustee for 60 days after its receipt of such notice,
request and offer of indemnity has failed to institute any such proceeding; and 
 (5) no direction inconsistent with such
written request has been given to the Trustee during such 60-day period by the Holders of a majority or more in principal amount of the Outstanding Notes; 

it being understood and intended that no one or more Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of the
Indenture or the Note Guarantees to affect, disturb or prejudice the rights of any other Holders, or to obtain or to seek to obtain priority or preference over any other Holders or to enforce any right under the Indenture or the Note Guarantees,
except in the manner herein provided and for the equal and ratable benefit of all the Holders (it being further understood that the Trustee does not have an affirmative duty to ascertain whether or not such actions or forbearances are unduly
prejudicial to such Holders). 
 SECTION 508. Unconditional Right of Holders To Receive Principal, Premium and Interest. 

Notwithstanding any other provision in the Indenture, the Holder of any Note shall have the right, which is absolute and unconditional, to
receive payment, as provided herein (including, if applicable, Article Eleven) and in such Note of the principal of (and premium, if any) and (subject to Section 307) interest on such Note on the respective Stated Maturities expressed in such
Note (or, in the case of redemption, on the Redemption Date) and to institute suit for the enforcement of any such payment, and such rights shall not be impaired without the consent of such Holder. 

  
 -35- 

 SECTION 509. Restoration of Rights and Remedies. 

If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under the Indenture or the Note Guarantees and such
proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, any other obligor of the
Notes, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been
instituted. 
 SECTION 510. Rights and Remedies Cumulative. 

Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes in the last paragraph of
Section 306, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in
addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or
employment of any other appropriate right or remedy. 
 SECTION 511. Delay or Omission Not Waiver. 

No delay or omission of the Trustee or of any Holder of any Note to exercise any right or remedy accruing upon any Event of Default shall
impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often
as may be deemed expedient, by the Trustee or by the Holders, as the case may be. 
 SECTION 512. Control by Holders. 

The Holders of not less than a majority in principal amount of the Outstanding Notes shall have the right to direct the time, method and place
of conducting any proceeding for exercising any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, provided that: 

(1) such direction shall not be in conflict with any rule of law or with the Indenture, 

(2) subject to Section 315 of the Trust Indenture Act, the Trustee may take any other action deemed proper by the Trustee
which is not inconsistent with such direction, and 
 (3) the Trustee need not take any action which might involve it in
personal liability or be unjustly prejudicial to the Holders not consenting. 
 SECTION 513. Waiver of Past Defaults. 

Subject to Sections 502, 508 and 902, the Holders of not less than a majority in principal amount of the Outstanding Notes may on behalf of the
Holders of all such Notes waive any past Default hereunder and its consequences, except a continuing Default or Event of Default (1) in respect of the payment of interest on, premium, if any, or the principal of any such Note held by a non-consenting Holder, or (2) in respect of a covenant or provision hereof which under Article Nine cannot be modified or amended without the consent of the Holder of each Outstanding Note affected. 

  
 -36- 

 Upon any such waiver, such Default shall cease to exist, and any Event of Default arising
therefrom shall be deemed to have been cured, for every purpose of the Indenture, but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon. 

SECTION 514. Waiver of Stay or Extension Laws. 

Each of the Company and any other obligor on the Notes covenants (to the extent that it may lawfully do so) that it will not at any time insist
upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of the Indenture; and each of
the Company and any other obligor on the Notes (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not hinder, delay or impede the execution of any power herein
granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

 SECTION 604. Trustee Not Responsible for Recitals or Issuance of Notes. 

The recitals contained herein and in the Notes, except for the Trustee’s certificates of authentication, shall be taken as the statements
of the Company, and the Trustee assumes no responsibility for their correctness. The Trustee makes no representations as to the validity or sufficiency of this Supplemental Indenture or of the Notes, except that the Trustee represents that it is
duly authorized to execute and deliver this Supplemental Indenture, authenticate the Notes and perform its obligations hereunder and that the statements made by it in a “Statement of Eligibility” on Form
T-1 supplied to the Company are true and accurate, subject to the qualifications set forth therein. The Trustee shall not be accountable for the use or application by the Company of Notes or the proceeds
thereof. 
 SECTION 605. May Hold Notes. 

The Trustee, any Paying Agent, any Note Registrar or any other agent of the Company or of the Trustee, in its individual or any other capacity,
may become the owner or pledgee of Notes and, subject to TIA Sections 310(b) and 311, may otherwise deal with the Company with the same rights it would have if it were not the Trustee, Paying Agent, Note Registrar or such other agent;
provided, however, that, if it acquires any conflicting interest, it must eliminate such conflict within 90 days, apply to the Commission for permission to continue or resign. 

SECTION 606. Money Held in Trust. 

Money held by the Trustee in trust hereunder need not be segregated from other funds except to the extent required by law. The Trustee shall be
under no liability for interest on any money received by it hereunder except as otherwise agreed in writing with the Company. 
 SECTION
607. Compensation and Reimbursement. 
 The Company agrees: 

(1) to pay to the Trustee from time to time such compensation as shall be agreed in writing between the Company and the Trustee
for all services rendered by it hereunder (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust); 

(2) except as otherwise expressly provided herein, to reimburse the Trustee upon its request for all reasonable expenses,
disbursements and advances incurred or made by the Trustee in accordance with any provision of this Supplemental Indenture (including the reasonable compensation and the expenses and disbursements of its agents and counsel), except any such expense,
disbursement or advance as shall be determined to have been caused by its own negligence or willful misconduct, as adjudicated by a court of competent jurisdiction; and 

  
 -40- 

 (3) to indemnify the Trustee and its officers, directors, agents and
employees and any predecessor Trustee for, and to hold it harmless against, any and all loss, liability, claim, damage or expense, including taxes (other than the taxes based on the income of the Trustee) and (including reasonable attorneys’
fees and expenses and court costs) incurred without negligence or willful misconduct, as adjudicated by a court of competent jurisdiction, on its part, arising out of or in connection with the acceptance or administration of this trust, (a) any
action, claim or suit brought to enforce the Trustee’s right to indemnification or (b) including the costs and expenses of defending itself against any claim regardless of whether the claim is asserted by the Company, a Holder or any other
Person or liability in connection with the exercise or performance of any of its powers or duties hereunder. The Trustee will notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company
will not relieve the Company of its obligations hereunder. The Company will defend the claim and the Trustee will cooperate in the defense. The Trustee shall have the right to employ separate counsel at the expense of the Company if in the judgment
of the Trustee (i) a conflict of interest exists by reason of common representation, (ii) there are legal defenses available to the Trustee that are different from or in addition to those available to the Company or (iii) if all
parties commonly represented do not agree to the action (or inaction) of counsel. The Company need not pay for any settlement made without its consent, which consent will not be unreasonably withheld. The Company need not reimburse any expense or
indemnify against any loss, liability or expense incurred by the Trustee through the Trustee’s own willful misconduct or negligence, as adjudicated by a court of competent jurisdiction. 

The obligations of the Company under this Section to compensate the Trustee, to pay or reimburse the Trustee for expenses, disbursements and
advances and to indemnify and hold harmless the Trustee shall constitute additional indebtedness hereunder and shall survive the satisfaction and discharge of this Supplemental Indenture and resignation or removal of the Trustee. As security for the
performance of such obligations of the Company, the Trustee shall have a claim prior to the Notes upon all property and funds held or collected by the Trustee as such, except funds held in trust for the payment of principal of (and premium, if any)
or interest on particular Notes. 
 When the Trustee incurs expenses or renders services in connection with an Event of Default specified in
Section 501(6), the expenses (including the reasonable charges and expenses of its counsel) of and the compensation for such services are intended to constitute expenses of administration under any applicable Federal or State bankruptcy,
insolvency or other similar law. 
 The provisions of this Section shall survive the termination of this Supplemental Indenture, the
resignation or removal of the Trustee and the satisfaction and discharge of this Supplemental Indenture. 
 SECTION 608. Corporate
Trustee Required; Eligibility. 
 There shall be at all times a Trustee hereunder which shall be eligible to act as Trustee under TIA
Sections 310(a)(1), (2) and (5) and shall have a combined capital and surplus of at least $50,000,000. If such corporation publishes reports of condition at least annually, pursuant to law or to the requirements of Federal, State, territorial
or District of Columbia supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of
condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this Article. 

  
 -41- 

 SECTION 609. Resignation and Removal; Appointment of Successor.

the acceptance of appointment by the successor Trustee in accordance with the applicable requirements of Section 610.

may resign at any time by giving written notice thereof to the Company. Upon receiving such notice of resignation, the Company shall promptly appoint a successor trustee by written instrument executed by authority of the Board of Directors, a copy
of which shall be delivered to the resigning Trustee and a copy to the successor trustee. If the instrument of acceptance by a successor Trustee required by Section 610 shall not have been delivered to the Trustee within 30 days after the
giving of such notice of resignation, the resigning Trustee may petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a successor Trustee. 

(c) The Trustee may be removed at any time by Act of the Holders of not less than a majority in principal amount of Outstanding Notes,
delivered to the Trustee and to the Company. If the instrument of acceptance by a successor Trustee required by Section 610 shall not have been delivered to the Trustee within 30 days after the giving of such notice of resignation, the
resigning Trustee may petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a successor Trustee. 

(d) If at any time: 

(1) the Trustee shall fail to comply with the provisions of TIA Section 310(b) after written request therefor by the
Company or by any Holder who has been a bona fide Holder of a Note for at least six months, or 
 (2) the Trustee shall cease
to be eligible under Section 608 and shall fail to resign after written request therefor by the Company or by any Holder who has been a bona fide Holder of a Note for at least six months, or 

(3) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent or a receiver of the Trustee or
of its property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, 

then, in any such case, (i) the Company, by a Board Resolution, may remove the Trustee, or (ii) subject to TIA Section 315(e), any Holder who
has been a bona fide Holder of a Note for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 

(e) If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any cause,
the Company shall promptly appoint a successor Trustee. If, within one year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee shall be appointed by Act of the Holders of a majority in principal
amount of the Outstanding Notes delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment, become the successor Trustee and supersede the successor Trustee
appointed by the Company. If no successor Trustee shall have been so appointed by the Company or the Holders and accepted appointment in the manner hereinafter provided, the Trustee or any Holder who has been a bona fide Holder of a Note for at
least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee. 

  
 -42- 

 (f) The Company shall give notice of each resignation and each removal of the Trustee and
each appointment of a successor Trustee to the Holders in the manner provided for in Section 1305. Each notice shall include the name of the successor Trustee and the address of its Corporate Trust Office. 

SECTION 610. Acceptance of Appointment by Successor. 

(a) Every successor Trustee appointed hereunder shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument
accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and
duties of the retiring Trustee; but, on request of the Company or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and
trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder. Upon request of any such successor Trustee, the Company shall execute any and all
instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts. The retiring Trustee shall have no responsibility or liability for the action or inaction of any successor Trustee. 

(b) Upon request of any such successor Trustee, the Company shall execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Trustee all rights, powers and trusts referred to in paragraph (a) of this Section. 
 (c) No successor
Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible under this Article. 

SECTION 611. Merger, Conversion, Consolidation or Succession to Business. 

Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any
merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all of the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided
such corporation shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Notes shall have been authenticated, but not
delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Notes so authenticated with the same effect as if such successor Trustee had
itself authenticated such Notes. In case at that time any of the Notes shall not have been authenticated, any successor Trustee may authenticate such Notes either in the name of any predecessor hereunder or in the name of the successor Trustee. In
all such cases such certificates shall have the full force and effect which this Supplemental Indenture provides for the certificate of authentication of the Trustee shall have; provided, however, that the right to adopt the
certificate of authentication of any predecessor Trustee or to authenticate Notes in the name of any predecessor Trustee shall apply only to its successor or successors by merger, conversion or consolidation. 

  
 -43- 

 SECTION 612. Appointment of Authenticating Agent. 

At any time when any of the Notes remain Outstanding, the Trustee may appoint an Authenticating Agent or Agents with respect to the Notes which
shall be authorized to act on behalf of the Trustee to authenticate Notes and the Trustee shall give written notice of such appointment to all Holders of Notes with respect to which such Authenticating Agent will serve, in the manner provided for in
Section 1305. Notes so authenticated shall be entitled to the benefits of this Supplemental Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Any such appointment shall be evidenced by an
instrument in writing signed by a Responsible Officer of the Trustee, and a copy of such instrument shall be promptly furnished to the Company. Wherever reference is made in this Supplemental Indenture to the authentication and delivery of Notes by
the Trustee or the Trustee’s certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the
Trustee by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the Company and shall at all times be a corporation organized and doing business under the laws of the United States of America, any state thereof or the District
of Columbia, authorized under such laws to act as Authenticating Agent, having a combined capital and surplus of not less than $150,000,000 and subject to supervision or examination by Federal or state authority. If such corporation publishes
reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such corporation shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so published. If at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and
with the effect specified in this Section. 
 Any corporation into which an Authenticating Agent may be merged or converted or with which it
may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to all or substantially all the corporate agency or corporate trust
business of an Authenticating Agent, shall continue to be an Authenticating Agent, provided such corporation shall be otherwise eligible under this Section, without the execution or filing of any paper or any further act on the part of the
Trustee or the Authenticating Agent. 
 An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee and
to the Company. The Trustee may at any time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Company. Upon receiving such a notice of resignation or upon such a termination, or
in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent which shall be acceptable to the Company and shall give written
notice of such appointment to all Holders of Notes, in the manner provided for in Section 1305. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers and duties of its
predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section. 

The Company agrees to pay to each Authenticating Agent from time to time such compensation for its services under this Section as shall be
agreed in writing between the Company and such Authenticating Agent.

addition to the Trustee’s certificate of authentication, an alternate certificate of authentication in the following form:

interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services; it being understood that the Trustee shall use reasonable efforts which are consistent with accepted practices in the banking industry to

Company shall give notice thereof to the Holders of each Outstanding Note affected, in the manner provided for in Section 1305, briefly setting forth in general terms the substance of such supplemental indenture. Any failure of the Company to
mail such notice, or any defect therein, will not, however, in any way impair or affect the validity of any such amended or supplemental indenture or waiver. 

SECTION 908. Payment for Consent. 

Neither the Company nor any Affiliate of the Company shall, directly or indirectly, pay or cause to be paid any consideration, whether by way

if any) or interest on any Notes, deposit with a Paying Agent a sum sufficient to pay the principal (and premium, if any) or interest so becoming due, such sum to be held in trust for the benefit of the Persons entitled to such principal, premium or
interest, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of such action or any failure so to act. 

The Company will cause each Paying Agent (other than the Trustee) to execute and deliver to the Trustee an instrument in which such Paying
Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent will: 
 (1) hold all
sums held by it for the payment of the principal of (and premium, if any) or interest on Notes in trust for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as herein provided; 

(2) give the Trustee notice of any default by the Company (or any other obligor upon the Notes) in the making of any payment of
principal (and premium, if any) or interest; and 
 (3) at any time during the continuance of any such default, upon the
written request of the Trustee, forthwith pay to the Trustee all sums so held in trust by such Paying Agent. 
 The Company may at any time,
for the purpose of obtaining the satisfaction and discharge of this Supplemental Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent,
such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by the Company or such Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further
liability with respect to such sums. 
 Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for
the payment of the principal of (or premium, if any) or interest on any Note and remaining unclaimed for two years after such principal, premium or interest has become due and payable shall be paid to the Company on Company Request, or (if then held
by the Company) shall be discharged from such trust; and the Holder of such Note shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to
such trust money, and all liability of the Company as Trustee thereof, shall thereupon cease. 
 SECTION 1004. Corporate Existence.

 Subject to Article Eight, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect its
corporate existence and that of each Subsidiary and the corporate rights (charter and statutory) and franchises of the Company and each Subsidiary; provided, however, that the Company shall not be required to preserve any such right or
franchise if the Board of Directors shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and its Subsidiaries as a whole.

 SECTION 1005. Payment of Taxes and Other Claims. 

The Company will pay or discharge or cause to be paid or discharged, before the same shall become delinquent, (a) all material taxes,
assessments and governmental charges levied or imposed upon the Company or any Subsidiary or upon the income, profits or property of the Company or any Subsidiary and (b) all material lawful claims for labor, materials and supplies, which, if
unpaid, might by law become a lien upon the property of the Company or any Subsidiary; provided, however, that the Company shall not be required to pay or discharge or cause to be paid or discharged any such tax, assessment, charge or
claim whose amount, applicability or validity is being contested in good faith by appropriate proceedings and for which appropriate reserves, if necessary (in the good faith judgment of management of the Company) are being maintained in accordance
with GAAP. 
 SECTION 1006. Maintenance of Properties. 

The Company will cause all properties owned by the Company or any Subsidiary or used or held for use in the conduct of its business or the
business of any Subsidiary to be maintained and kept in good condition, repair and working order and supplied with all necessary equipment and will cause to be made all necessary repairs, renewals, replacements, betterments and improvements thereof,
all as in the judgment of the Company may be necessary so that the business carried on in connection therewith may be properly and advantageously conducted at all times; provided, however, that nothing in this Section shall prevent the
Company from discontinuing the maintenance of any of such properties if such discontinuance is, in the judgment of the Company, desirable in the conduct of its business or the business of any Subsidiary. 

SECTION 1007. Insurance. 

(a) The Company will at all times keep all of its and its Subsidiaries’ properties which are of an insurable nature insured with insurers,
believed by the Company to be responsible (including, to the extent consistent with past practice, self-insurance), against loss or damage to the extent that property of similar character is usually so insured by corporations similarly situated and
owning like properties. 
 (b) In connection with the covenants set forth in this Section 1007, it is understood and agreed that: 

(i) none of the Trustee nor its respective agents or employees shall be liable for any loss or damage insured by the insurance
policies required to be maintained under this Section 1007, it being understood that (A) the Company shall look solely to its insurance companies or any other parties other than the aforesaid parties for the recovery of such loss or damage
and (B) such insurance companies shall have no rights of subrogation against the Trustee, or its agents or employees. If, however, the insurance policies do not provide waiver of subrogation rights against such parties, as required above, then
the Company hereby agrees, to the extent permitted by law, to waive, its right of recovery, if any, against the Trustee and the Holder and its agents and employees; and 

(ii) the designation of any form, type or amount of insurance coverage by the Trustee under this Section 1007 shall in no
event be deemed a representation, warranty or advice by the Trustee that such insurance is adequate for the purposes of the business of Company or the protection of its properties.

 SECTION 1008. Statement by Officers as to Default. 

(a) The Company will deliver to the Trustee within 120 days after the end of each fiscal year, an Officers’ Certificate signed by the
principal executive officer, the principal financial officer or principal accounting officer stating that a review of the activities of the Company and its Subsidiaries during the preceding fiscal year has been made under the supervision of the
signing officers with a view to determining whether it has kept, observed, performed and fulfilled, and has caused each of its Subsidiaries to keep, observe, perform and fulfill its obligations under the Indenture and further stating, as to each

signers do know of such Default or Event of Default, the certificate shall describe its status, with particularity and that, to the best of his or her knowledge, no event has occurred and remains by reason of which payments on the account of the
principal of or interest, if any, on the Notes is prohibited or if such event has occurred, a description of the event and what action each is taking or proposes to take with respect thereto. The Officers’ Certificate shall also notify the

requirement of notice under the Indenture.

Indenture, or (ii) if the trustee for or the holder of any other evidence of Indebtedness of the Company or any Subsidiary gives any notice or takes any other action with respect to a claimed default (other than with respect to Indebtedness in

other action within ten Business Days of any Officer becoming aware of the foregoing.

otherwise report on an annual and quarterly basis on forms provided for such annual and quarterly reporting pursuant to rules and regulations promulgated by the Commission, the Company shall file with the Commission (and make available to the

 provided that (A) at any time that the Company is not subject to the reporting
requirements of Section 13 or 15(d) of the Exchange Act, none of such reports will be required to (i) comply with Section 302, 404 and 906 of the Sarbanes-Oxley Act of 2002, or related Items 307 and 308 of Regulation S-K promulgated by the Commission, or Item 10(e) of Regulation S-K (with respect to any non-GAAP financial measures contained therein),
(ii) contain the information required by Items 201, 402, 403, 405, 406, 407, 701 or 703 of Regulation S-K, (iii) contain the separate financial information contemplated by Rules 3-10 or 3-16 of Regulation S-X promulgated by the Commission and (iv) provide financial statements in interactive data format

information to prospective purchasers of the Notes, in addition to providing such information to the Trustee and the Holders in each case within 15 days after the time the Company would be required to file such information with the Commission, if it
were subject to Section 13 or 15(d) of the Exchange Act; provided further that nothing in this Section shall excuse the Company from complying with the provisions of Section 314(a) of the Trust Indenture Act. 

The Company shall be deemed to have furnished such information referred to in this covenant to the Trustee and the Holders of Notes if the
Company has filed or furnished such information in reports filed with the Commission and such reports are publicly available on the Commission’s website; provided, however, that the Trustee shall have no obligation whatsoever to
determine whether or not such information, documents or reports have been so filed or furnished. 
 Delivery of such reports, information
and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the

 -55- 

 (7) if such notice is mailed prior to the occurrence of a Change of Control

(8) that Holders whose Notes are being purchased only in part will be issued new Notes equal in principal amount to the
unpurchased portion of the Notes surrendered, which unpurchased portion must be equal to $2,000 in principal amount or an integral multiple of $1,000 in excess thereof. 

(b) While the Notes are in global form and the Company makes an offer to purchase all of the Notes pursuant to the Change of Control Offer, a
Holder may exercise its option to elect for the purchase of the Notes through the facilities of Depositary, Euroclear and Clearstream, subject to their rules and regulations. 

(c) If Holders of not less than 90% in aggregate principal amount of the Outstanding Notes validly tender and do not withdraw such Notes in a

Interest Payment Date. 
 (d) The Company shall not be required to make a Change of Control Offer following a Change of Control Triggering
Event if (1) a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Supplemental Indenture applicable to a Change of Control Offer made by the Company and
purchases all Notes validly tendered and not withdrawn under such Change of Control Offer or (2) notice of redemption has been given pursuant to this Supplemental Indenture as described under Section 1101, unless and until there is a
default in payment of the applicable redemption price. Notwithstanding anything to the contrary herein, a Change of Control Offer may be made in advance of a Change of Control Triggering Event, conditional upon such Change of Control. 

(e) The Company shall comply with the requirements of Section 14(e) under the Exchange Act and any other securities laws and regulations
thereunder to the extent such laws or regulations are applicable in connection with the repurchase of Notes pursuant to a Change of Control Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions
of this Supplemental Indenture, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations described in this Supplemental Indenture by virtue thereof. 

(f) On the Change of Control Payment Date, the Company shall, to the extent permitted by law, 

(1) accept for payment all Notes or portions thereof properly tendered pursuant to the Change of Control Offer, 

(2) deposit with the Paying Agent an amount equal to the aggregate Change of Control Payment in respect of all Notes or
portions thereof so tendered, and 

  
 -56- 

 (3) deliver, or cause to be delivered, to the Trustee for cancellation the
Notes so accepted together with an Officers’ Certificate stating that such Notes or portions thereof have been tendered to and purchased by the Company. 

(g) The Paying Agent shall promptly mail to each Holder of Notes the Change of Control Payment for such Notes, and the Trustee will promptly
authenticate and mail to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided that each such new Note shall be in a principal amount of $2,000 or an integral multiple of $1,000

SECTION 1017. [Reserved]. 

SECTION 1018. Waiver of Certain Covenants. 

The Company and its Subsidiaries may omit in any particular instance to comply with any term, provision or condition set forth in or Sections
1004 through 1008, inclusive, if before or after the time for such compliance the Holders of at least a majority in principal amount of the Outstanding Notes, by Act of such Holders, waive such compliance in such instance with such term, provision
or condition, but no such waiver shall extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the duties of the Trustee in
respect of any such term, provision or condition shall remain in full force and effect. 
 SECTION 1019. [Reserved]. 

SECTION 1020. Note Guarantees. 

From and after the Issue Date and prior to the Existing Notes Repayment Date, the Company will not cause or permit (i) any of its
Subsidiaries (other than a Guarantor or a Majority Owned JV), directly or indirectly, to guarantee any capital markets Indebtedness or any unsecured credit facility of the Company or any Guarantor or (ii) any Majority Owned JV, directly or
indirectly, to guarantee any capital markets Indebtedness or any unsecured credit facility of the Company, in each case, with an aggregate principal amount in excess of the greater of (x) $125.0 million and (y) 1.75% of Total Assets, unless
such Subsidiary: 
 (a) within 20 Business Days of the date on which it guarantees such Indebtedness of the Company or any
Guarantor executes and delivers to the Trustee a supplemental indenture pursuant to which such Subsidiary shall guarantee (each, a “Note Guarantee”) all of the Company’s obligations under the Notes and this Supplemental Indenture and
other terms contained in the applicable supplemental indenture and subject to the conditions contained in such supplemental indenture; and 

(b) delivers to the Trustee an Officers’ Certificate that all conditions precedent to the execution of such supplemental
indenture have been complied with. 
 Thereafter, such Subsidiary shall be a Guarantor for all purposes of this Supplemental Indenture until
such Note Guarantee is released in accordance with the provisions of this Supplemental Indenture. In the event of a sale or other transfer or disposition of all of the Capital Stock in any Guarantor to any Person that is not an Affiliate of the
Company in compliance with the terms of this Supplemental Indenture, or in the event all or substantially all the assets or Capital Stock of a Guarantor 

  
 -57- 

 
are sold or otherwise transferred, by way of merger, consolidation or otherwise, to a Person that is not an Affiliate of the Company in compliance with the terms of this Supplemental Indenture,
then, without any further action on the part of the Trustee or any Holder, such Guarantor (or the Person concurrently acquiring such assets of such Guarantor) shall be deemed automatically and unconditionally cancelled, released and discharged of
any obligations under its Note Guarantee, as evidenced by a supplemental indenture, written instrument or confirmation executed by the Trustee, upon request; provided, however that if evidence of such cancellation, discharge or release
is requested to be executed by the Trustee, an Officers’ Certificate and an Opinion of Counsel complying with Section 1301 of this Supplemental Indenture. In addition, upon the release or discharge of any guarantee which resulted in the
creation of a Note Guarantee (except a discharge or release by or as a result of payment under such guarantee), the Guarantor of such Note Guarantee shall be deemed automatically and unconditionally cancelled, released and discharged of any
obligations under its Note Guarantee, as evidenced by a supplemental indenture, written instrument or confirmation executed by the Trustee, upon request. The Company may cause any other Subsidiary of the Company to issue a Note Guarantee and become
a Guarantor. 
 Each Note Guarantee by a Subsidiary will be limited to an amount not to exceed the maximum amount that can be guaranteed by
that Subsidiary without rendering the Note Guarantee, as it relates to such Subsidiary, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally. 

SECTION 1021. Additional Amounts. 

If the Company (or a Guarantor, if any) or other applicable withholding agent is required by law to deduct or withhold taxes imposed by Bermuda
or another Relevant Tax Jurisdiction on payments to Holders, it will pay to any Holder so entitled all additional amounts that may be necessary so that every Net Payment of interest, principal, premium or other amount received by the beneficial
owner on that Note or the guarantee will not be less than the amount provided for in that Note or the Note Guarantee. 
 (a)
The Company (and Guarantors, if any) will also indemnify and reimburse Holders for: 
 (1) Taxes (including any interest,
penalties and related expenses) imposed on the Holders (or if a Holder is not the beneficial owner, the beneficial owner) by a Relevant Tax Jurisdiction if and to the same extent that a Holder would have been entitled to receive additional amounts
if the Company (or a Guarantor) or other applicable withholding agent had been required to deduct or withhold those taxes from payments on the Notes or the Note Guarantees; and 

(2) Stamp, court, documentary or similar taxes or charges (including any interest, penalties and related expenses) imposed by a
Relevant Tax Jurisdiction in connection with the execution, delivery, enforcement or registration of the Notes or the Note Guarantees or other related documents and obligations. 

(b) The Company (or a Guarantor) will not pay additional amounts to any Holder for or on account of any of the following: 

(1) Any tax, assessment or other governmental charge imposed solely because at any time there is or was a connection between
such Holder (or between a fiduciary, settlor, beneficiary, member or shareholder of or possessor of power over the relevant holder if the holder is an estate, nominee, trust, partnership, limited liability company, or corporation) and the Relevant
Tax Jurisdiction imposing the tax (other than the mere receipt of a payment or the acquisition, ownership, disposition or holding of, or enforcement of rights under, a Note or the Note Guarantees); 

  
 -58- 

 (2) Any estate, inheritance, gift or any similar tax, assessment or other
governmental charge; 
 (3) Any tax, assessment or other governmental charge imposed solely because such Holder (or if such
Holder is not the beneficial owner, the beneficial owner) fails to comply with any certification, identification or other reporting requirement concerning the nationality, residence, identity or connection with the taxing jurisdiction of such Holder
or any beneficial owner of the Note or the Note Guarantees, if compliance is required by law or by an applicable income tax treaty to which the jurisdiction imposing the tax is a party, as a precondition to an exemption from the tax, assessment or
other governmental charge for which such Holder is eligible and the Company (or a Guarantor) has given the Holders at least 60 days’ notice that Holders will be required to provide such information and identification; and 

(4) Any tax, assessment or other governmental charge with respect to a Note or a Note Guarantee presented for payment more than
30 days after the date on which payment became due and payable or the date on which payment thereof is duly provided for and notice thereof given to Holders, whichever occurs later, except to the extent that such Holder of the Note would have been
entitled to additional amounts on presenting the Note for payment on any date during the 30-day period. 

ARTICLE ELEVEN 

REDEMPTION OF NOTES 

Article IV of the Base Indenture is hereby modified, amended, supplemented and deleted as it relates to the Notes except as described in, and
to the extent of, this Article Eleven. 
 SECTION 1101. Right of Redemption. 

(a) Prior to April 15, 2026, the Company may, at any time and from time to time, redeem all or a part of the Notes, upon not less than 15
nor more than 60 days’ prior notice mailed by first class mail to each Holder’s registered address, at a Redemption Price equal to the greater of (a) 100% of the principal amount of the Notes redeemed, plus accrued and unpaid interest
thereon to, but not including, the Redemption Date, and (b) the sum of the present values of 100% of the principal amount of the Notes being redeemed and the remaining scheduled payments of interest on the Notes from the Redemption Date through
April 15, 2026 (computed using a discount rate equal to the Treasury Rate as of such Redemption Date plus 25 basis points), plus accrued and unpaid interest to, but not including, the Redemption Date. 

(b) On and after April 15, 2026, the Company may on any one or more occasions redeem all or a part of the Notes, upon not less than 15 nor
more than 60 days’ prior notice mailed by first class mail to each Holder’s registered address, at a Redemption Price equal to 100% of the aggregate principal amount thereof, plus accrued and unpaid interest thereon, if any, to, but not
including, the Redemption Date, subject to the right of Holders of record on the relevant Record Date to receive interest due on the relevant Interest Payment Date. 

  
 -59- 

 (c) Any notice of redemption may, at the Company’s option and discretion, be subject to
one or more conditions precedent, including, but not limited to, completion of any debt or equity financing, acquisition or other corporate transaction. In addition, if such redemption is subject to satisfaction of one or more conditions precedent,
such notice shall state that, in the Company’s sole discretion, the redemption date may be delayed until such time as any or all such conditions shall be satisfied, or such redemption may not occur and such notice may be rescinded in the event
that any or all such conditions shall not have been satisfied by the redemption date, or by the redemption date so delayed. In addition, the Company may provide in such notice that payment of the redemption price and performance of the
Company’s obligations with respect to such redemption may be performed by another Person (it being understood that any such provision for payment by another Person will not relieve the Company and the Guarantors from their obligations with
respect to such redemption). 
 (d) The Company shall provide at least two Business Days’ prior written notice to the Trustee prior to
the Redemption Date (or such lesser period as the Trustee may agree to) if any such redemption is being rescinded or delayed, and upon receipt, the Trustee shall promptly provide such notice to each Holder of the Notes in the manner provided for in
Section 1305. 
 (e) In addition to the Company’s rights to redeem Notes as set forth in subclauses (a) through (d) above, the
Company may at any time purchase Notes in open-market transactions, tender offers, privately negotiated transactions or otherwise. 

SECTION 1102. Redemption for Taxation Reasons. 

The Company will be entitled, at its option, to redeem the Notes in whole if at any time it becomes obligated to pay additional amounts on the
Notes on the next Interest Payment Date with respect to the Notes, but only if the obligation results from a change in, or an amendment to, the laws or treaties (including any regulations or official rulings promulgated thereunder) of a Relevant Tax
Jurisdiction (or a political subdivision or taxing authority thereof or therein), or from a change in any official position regarding the interpretation, administration or application of those laws, treaties, regulations or official rulings
(including a change resulting from a holding, judgment or order by a court of competent jurisdiction), that becomes effective and is announced after the Issue Date (or, if the applicable Relevant Tax Jurisdiction became a Relevant Tax Jurisdiction
on a date after the Issue Date, such later date) and provided the Company cannot avoid the obligation after taking reasonable measures to do so. If the Company redeems the Notes in these circumstances, it will do so at a Redemption Price
equal to 100% of the principal amount of the Notes redeemed, plus accrued and unpaid interest, if any, and any other amounts due to the redemption date. 

If the Company becomes entitled to redeem the Notes in these circumstances, it may do so at any time on a redemption date of its choice.
However, the Company must give the Holders of Notes being redeemed notice of the redemption not less than 15 days or more than 60 days before the redemption date and not more than 90 days before the next date on which it would be obligated to pay
additional amounts. In addition, the Company’s obligation to pay additional amounts must remain in effect when it gives the notice of redemption. Notice of the Company’s intent to redeem the Notes shall not be effective until such time as
it delivers to the Trustee both a certificate signed by two of its officers stating that the obligation to pay additional amounts cannot be avoided by taking reasonable measures and an opinion of independent legal counsel or an independent auditor
stating that the Company is obligated to pay additional amounts because of an amendment to or change in law, treaties or position as described in the preceding paragraph. In addition to the Company’s rights to redeem Notes as set forth above,
the Company may at any time and from time to time purchase Notes in open-market transactions, tender offers or otherwise. 

  
 -60- 

 SECTION 1103. Applicability of Article. 

Redemption of Notes at the election of the Company or otherwise, as permitted or required by any provision of this Supplemental Indenture,
shall be made in accordance with such provision and this Article. 
 SECTION 1104. Election To Redeem; Notice to Trustee. 

The election of the Company to redeem any Notes pursuant to Section 1101 above shall be evidenced by a Company Order. In case of any
redemption at the election of the Company, the Company shall, at least 35 days prior to the Redemption Date fixed by the Company (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee of such Redemption Date and of the
principal amount of Notes to be redeemed and shall deliver to the Trustee such documentation and records as shall enable the Trustee to select the Notes to be redeemed pursuant to Section 1105. 

SECTION 1105. Selection by Trustee of Notes To Be Redeemed. 

If less than all of the Notes are to be redeemed at any time, selection of such Notes for redemption, will be made by the Trustee in compliance
with the requirements of the principal national securities exchange and DTC procedures, if any, on which such Notes are listed, or, if such Notes are not so listed, on a pro rata basis or by lot or such similar method in accordance with the
procedures of DTC; provided that no Notes of $2,000 or less shall be purchased or redeemed in part. 
 Notices of purchase or
redemption shall be mailed by first class mail, postage prepaid, at least 15 but not more than 60 days before the purchase or redemption date to each Holder of Notes to be purchased or redeemed at such Holder’s registered address. If any Note
is to be purchased or redeemed in part only, any notice of purchase or redemption that relates to such Note shall state the portion of the principal amount thereof that has been or is to be purchased or redeemed. 

A new Note in principal amount equal to the unpurchased or unredeemed portion of any Note purchased or redeemed in part will be issued in the
name of the Holder thereof upon cancellation of the original Note. On and after the purchase or Redemption Date, unless the Company defaults in payment of the purchase or Redemption Price, interest shall cease to accrue on Notes or portions thereof
purchased or called for redemption. 
 SECTION 1106. Notice of Redemption. 

Notice of redemption shall be given in the manner provided for in Section 1305 not less than 15 nor more than 60 days prior to the
Redemption Date, to each Holder to be redeemed. Except as set forth in Section 1101(c), notices of redemption may not be conditional. 

All notices of redemption shall state: 

(1) the Redemption Date, 

(2) the Redemption Price and the amount of accrued interest to the Redemption Date payable as provided in Section 1108, if
any, 
 (3) if less than all Outstanding Notes are to be redeemed, the identification (and, in the case of a partial
redemption, the principal amounts) of the particular Notes to be redeemed, 

  
 -61- 

 (4) in case any Note is to be redeemed in part only, the notice which
relates to such Note shall state that on and after the Redemption Date, upon surrender of such Note, the holder will receive, without charge, a new Note or Notes of authorized denominations for the principal amount thereof remaining unredeemed, 

(5) that on the Redemption Date the Redemption Price (and accrued interest, if any, to the Redemption Date payable as provided
in Section 1108) will become due and payable upon each such Note, or the portion thereof, to be redeemed, and that interest thereon will cease to accrue on and after said date, 

(6) the place or places where such Notes are to be surrendered for payment of the Redemption Price and accrued interest, if
any, 
 (7) the name and address of the Paying Agent, 

(8) that Notes called for redemption must be surrendered to the Paying Agent to collect the Redemption Price, 

(9) the CUSIP number, and that no representation is made as to the accuracy or correctness of the CUSIP number, if any, listed
in such notice or printed on the Notes, 
 (10) the paragraph of the Notes pursuant to which the Notes are to be redeemed;
and 
 (11) any condition to such redemption. 

Notice of redemption of Notes to be redeemed at the election of the Company shall be given by the Company or, at the Company’s request,
upon notice to the Trustee of at least 35 days prior to such Redemption Date (unless a shorter notice shall be satisfactory to the Trustee) by the Trustee in the name and at the expense of the Company. 

SECTION 1107. Deposit of Redemption Price. 

On or before 10:00 a.m. New York City time on Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the
Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 1003) an amount of money sufficient to pay the Redemption Price of, and accrued interest, if any, on, all the Notes which are to be redeemed on that
date. The Trustee or the Paying Agent will promptly return to the Company any money deposited with the Trustee or the Paying Agent by the Company in excess of the amounts necessary to pay the redemption or purchase price of, and accrued interest, if
any, on, all Notes to be redeemed or purchased. 
 SECTION 1108. Notes Payable on Redemption Date. 

Notice of redemption having been given as aforesaid, the Notes so to be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified (together with accrued interest to the Redemption Date) (except as provided in Section 1101(e)), and from and after such date (unless the Company shall default in the payment of the Redemption Price and
accrued interest) such Notes shall cease to bear interest. Upon surrender of any such Note for redemption in accordance with said notice, such Note shall be paid by the Company at the Redemption Price, together with accrued interest to the
Redemption Date; provided, however, that installments of interest whose Stated Maturity is on or prior to the Redemption Date shall be payable to the Holders of such Notes, or one or more Predecessor Notes, registered as such at the
close of business on the relevant Record Dates according to their terms and the provisions of Section 307. 

  
 -62- 

 If any Note called for redemption shall not be so paid upon surrender thereof for
redemption, the principal (and premium, if any) shall, until paid, bear interest from the Redemption Date at the rate borne by the Notes. 

SECTION 1109. Notes Redeemed in Part. 

Any Note which is to be redeemed only in part (pursuant to the provisions of this Article) shall be surrendered at the office or agency of the
Company maintained for such purpose pursuant to Section 1002 (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the
Holder thereof or such Holder’s attorney duly authorized in writing), and the Company shall execute, and the Trustee shall authenticate and deliver to the Holder of such Note without service charge, a new Note or Notes, of any authorized
denomination as requested by such Holder, in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Note so surrendered. 

ARTICLE TWELVE 

DEFEASANCE AND COVENANT DEFEASANCE 

Article XII of the Base Indenture is hereby modified, amended, supplemented and deleted as it relates to the Notes except as described in, and
to the extent of, this Article Twelve. 
 SECTION 1201. Company’s Option To Effect Legal Defeasance or Covenant
Defeasance. 
 The Company may, at its option by Board Resolution, at any time, with respect to the Notes, elect to have either
Section 1202 or Section 1203 applied to all Outstanding Notes upon compliance with the conditions set forth below in this Article Twelve. 

SECTION 1202. Legal Defeasance and Discharge. 

Upon the Company’s exercise under Section 1201 of the option applicable to this Section 1202, the Company shall be deemed to
have been discharged from its respective obligations with respect to all Outstanding Notes on the date the conditions set forth in Section 1204 are satisfied (hereinafter, “Legal Defeasance”). For this purpose, such Legal Defeasance
means that the Company shall be deemed to have paid and discharged the entire indebtedness represented by the Outstanding Notes, which shall thereafter be deemed to be “Outstanding” only for the purposes of Section 1205 and the other
Sections of this Supplemental Indenture referred to in (A) and (B) below, and to have satisfied all its other obligations under such Notes and this Supplemental Indenture insofar as such Notes are concerned (and the Trustee, at the expense of
the Company, shall execute proper instruments acknowledging the same), except for the following which shall survive until otherwise terminated or discharged hereunder: (A) the rights of Holders of Outstanding Notes to receive payments in
respect of the principal of (and premium, if any, on) and interest on such Notes when such payments are due, solely out of the trust described in Section 1204, (B) the Company’s obligations with respect to such Notes under Sections 304,
305, 306, 1002 and 1003, (C) the rights, powers, trusts, duties and immunities of the Trustee hereunder, and the obligations of the Company in connection therewith and (D) this Article Twelve. Subject to compliance with this Article Twelve, the
Company may exercise its option under this Section 1202 notwithstanding the prior exercise of its option under Section 1203 with respect to the Notes. 

  
 -63- 

 SECTION 1203. Covenant Defeasance. 

Upon the Company’s exercise under Section 1201 of the option applicable to this Section 1203, the Company shall be released from
its respective obligations under any covenant contained in Sections 801, 802 and in Sections 1005, 1006, 1007, 1009 through 1018 with respect to the Outstanding Notes on and after the date the conditions set forth below are satisfied (hereinafter,
“Covenant Defeasance”), and the Notes shall thereafter be deemed not to be “Outstanding” for the purposes of any direction, waiver, consent or declaration or Act of Holders (and the consequences of any thereof) in connection with
such covenants, but shall continue to be deemed “Outstanding” for all other purposes hereunder. For this purpose, such Covenant Defeasance means that, with respect to the Outstanding Notes, the Company, may omit to comply with and shall
have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to
any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Sections 501(3), 501(4) and 501(5) and, with respect to only any Significant Subsidiary and not the Company,
Section 501(6), but, except as specified above, the remainder of this Supplemental Indenture and such Notes shall be unaffected thereby. 

SECTION 1204. Conditions to Legal Defeasance or Covenant Defeasance. 

The following shall be the conditions to application of either Section 1202 or Section 1203 to the Outstanding Notes: 

(1) The Company shall irrevocably have deposited or caused to be deposited with the Trustee (or another trustee satisfying the
requirements of Section 608 who shall agree to comply with the provisions of this Article Twelve applicable to it) as trust funds in trust for the purpose of making the following payments, specifically pledged as security for, and dedicated
solely to the benefit of the Holders of such Notes; (A) cash in U.S. dollars, or (B) Government Securities, or (C) a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized investment
banking firm, appraisal firm or firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, to pay and discharge, and which shall be applied by the Trustee (or other qualifying trustee) to pay and
discharge, the principal of (and premium, if any) and interest on the Outstanding Notes on the Stated Maturity (or Redemption Date, if applicable); provided that the Trustee shall have been irrevocably instructed to apply such cash or the
proceeds of such Government Securities to said payments with respect to the Notes; provided, further, that with respect to any redemption pursuant to Section 1101(b), the amount deposited shall be sufficient to the extent that an
amount is deposited with the Trustee equal to the amount calculated under Section 1101(b) as of the date of the notice of redemption, provided, further, that the Company shall deposit any Applicable Premium Deficit with the
Trustee on or prior to the Redemption Date and shall simultaneously deliver to the Trustee an Officer’s Certificate which shall set forth the Applicable Premium Deficit and confirm that such Applicable Premium Deficit shall be applied toward
such redemption. Before such a deposit, the Company may give to the Trustee, in accordance with Section 1104 hereof, a notice of its election to redeem all of the Outstanding Notes at a future date in accordance with Article Eleven hereof,
which notice shall be irrevocable. Such irrevocable redemption notice, if given, shall be given effect in applying the foregoing; 

(2) in the case of Legal Defeasance, the Company shall have delivered to the Trustee an Opinion of Counsel in the United States
reasonably acceptable to the Trustee confirming that, subject to customary assumptions and exclusions, 

  
 -64- 

 (A) the Company has received from, or there has been published by, the
United States Internal Revenue Service a ruling, or 
 (B) since the issuance of the Notes, there has been a change in the
applicable U.S. Federal income tax law, 
 in either case to the effect that, and based thereon such Opinion of Counsel in the United States
shall confirm that, subject to customary assumptions and exclusions, the Holders of the Outstanding Notes will not recognize income, gain or loss for U.S. Federal income tax purposes as a result of such Legal Defeasance and will be subject to U.S.
Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred; 

(3) in the case of Covenant Defeasance, the Company shall have delivered to the Trustee an Opinion of Counsel in the United
States reasonably acceptable to the Trustee confirming that, subject to customary assumptions and exclusions, the Holders of the Outstanding Notes will not recognize income, gain or loss for U.S. Federal income tax purposes as a result of such
Covenant Defeasance and will be subject to U.S. Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred; 

(4) no Default or Event of Default with respect to the Outstanding Notes (other than that resulting from borrowing funds to be
applied to make such deposit or the granting of Liens in connection therewith) shall have occurred and be continuing on the date of such deposit; 

(5) such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under
any other material agreement or instrument (other than this Supplemental Indenture) to which, the Company is a party or by which the Company is bound (other than that resulting from borrowing funds to be applied to make such deposit and the granting
of Liens in connection therewith); and 
 (6) the Company shall have delivered to the Trustee an Officers’ Certificate
and an Opinion of Counsel in the United States (which Opinion of Counsel may be subject to customary assumptions and exclusions), each stating that all conditions precedent provided for or relating to the Legal Defeasance or the Covenant Defeasance,
as the case may be, have been complied with. 
 SECTION 1205. Deposited Money and Government Securities To Be Held in Trust; Other
Miscellaneous Provisions. 
 Subject to the provisions of the last paragraph of Section 1003, all cash and Government Securities
(including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 1205, the “Trustee”) pursuant to Section 1204 in respect of the Outstanding Notes shall be held
in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Supplemental Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee
may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal (and premium, if any) and interest, but such money or Government Securities need not be segregated from other funds except to the extent
required by law. 
 The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the
Government Securities deposited pursuant to Section 1204 or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the Outstanding Notes. 

  
 -65- 

 Anything in this Article Twelve to the contrary notwithstanding, the Trustee shall deliver
or pay to the Company from time to time upon Company Request any money or Government Securities held by it as provided in Section 1204 which, in the opinion of a nationally recognized firm of independent public accountants expressed in a
written certification thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance, as applicable, in accordance with this Article.

 SECTION 1206. Reinstatement. 

If the Trustee or any Paying Agent is unable to apply any money or Government Securities in accordance with Section 1205 by reason of any
order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s obligations under this Supplemental Indenture and the Outstanding Notes shall be revived and
reinstated as though no deposit had occurred pursuant to Section 1202 or 1303, as the case may be, until such time as the Trustee or Paying Agent is permitted to apply all such money or Government Securities in accordance with
Section 1205; provided, however, that if the Company makes any payment of principal of (or premium, if any) or interest on any Note following the reinstatement of its obligations, the Company shall be subrogated to the rights of
the Holders of such Notes to receive such payment from the money or Government Securities held by the Trustee or Paying Agent. 
 ARTICLE
THIRTEEN 
 MISCELLANEOUS PROVISIONS 

Each of Article XVI and Section 6.05 of the Base Indenture is hereby modified, amended, supplemented and deleted as it relates to the
Notes except as described in, and to the extent of, this Article Thirteen. 
 SECTION 1301. Compliance Certificates and Opinions.

 Upon any application or request by the Company to the Trustee to take any action under any provision of this Supplemental Indenture, the
Company shall furnish to the Trustee an Officers’ Certificate stating that all conditions precedent, if any, provided for in this Supplemental Indenture (including any covenant compliance with which constitutes a condition precedent) relating
to the proposed action have been complied with and an Opinion of Counsel stating that in the opinion of such counsel all such conditions precedent, if any, have been complied with, except that in the case of any such application or request as to
which the furnishing of such documents is specifically required by any provision of this Supplemental Indenture relating to such particular application or request, no additional certificate or opinion need be furnished. 

Every certificate or opinion with respect to compliance with a condition or covenant provided for in this Supplemental Indenture (other than
pursuant to Section 1008(a)) shall include: 
 (1) a statement that each individual signing such certificate or opinion
has read such covenant or condition and the definitions herein relating thereto; 
 (2) a brief statement as to the nature
and scope of the examination or investigation upon which the statements or opinions contained in such certificate or opinion are based; 

  
 -66- 

 (3) a statement that, in the opinion of each such individual, he has made
such examination or investigation as is necessary to enable him to express an informed opinion as to whether or not such covenant or condition has been complied with; and 

(4) a statement as to whether, in the opinion of each such individual, such condition or covenant has been complied with. 

SECTION 1302. Form of Documents Delivered to Trustee. 

In any case where several matters are required to be certified by, or covered by an opinion of, any specified Person, it is not necessary that
all such matters be certified by, or covered by the opinion of, only one such Person, or that they be so certified or covered by only one document, but one such Person may certify or give an opinion with respect to some matters and one or more other
such Persons as to other matters, and any such Person may certify or give an opinion as to such matters in one or several documents. 
 Any
certificate or opinion of an officer of the Company may be based, insofar as it relates to legal matters, upon a certificate or opinion of, or representations by, counsel, unless such officer knows, or in the exercise of reasonable care should know,
that the certificate or opinion or representations with respect to the matters upon which his certificate or opinion is based are erroneous. Any such certificate or opinion may be based, insofar as it relates to factual matters, upon a certificate
or opinion of, or representations by, an officer or officers of the Company stating that the information with respect to such factual matters is in the possession of the Company, unless such counsel knows, or in the exercise of reasonable care
should know, that the certificate or opinion or representations with respect to such matters are erroneous. 
 Where any Person is required
to make, give or execute two or more applications, requests, consents, certificates, statements, opinions or other instruments under this Supplemental Indenture, they may, but need not, be consolidated and form one instrument. 

SECTION 1303. Acts of Holders. 

(a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Supplemental Indenture to be given
or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by agents duly appointed in writing; and, except as herein otherwise expressly provided, such action
shall become effective when such instrument or instruments are delivered to the Trustee and, where it is hereby expressly required, to the Company. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein
sometimes referred to as the “Act” of the Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Supplemental
Indenture and conclusive in favor of the Trustee and the Company, if made in the manner provided in this Section. 
 (b) The fact and date of
the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that
the individual signing such instrument or writing acknowledged to him the execution thereof. Where such execution is by a signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient
proof of authority. The fact and date of the execution of any such instrument or writing, or the authority of the Person executing the same, may also be proved in any other manner that the Trustee deems sufficient. 

  
 -67- 

 (c) The principal amount and serial numbers of Notes held by any Person, and the date of
holding the same, shall be proved by the Note Register. 
 (d) If the Company shall solicit from the Holders any request, demand,
authorization, direction, notice, consent, waiver or other Act, the Company may, at its option, by or pursuant to a Board Resolution, fix in advance a record date for the determination of Holders entitled to give such request, demand, authorization,
direction, notice, consent, waiver or other Act, but the Company shall have no obligation to do so. Notwithstanding TIA Section 316(c), such record date shall be the record date specified in or pursuant to such Board Resolution, which shall be
a date not earlier than the date 30 days prior to the first solicitation of Holders generally in connection therewith and not later than the date such solicitation is completed. If such a record date is fixed, such request, demand, authorization,
direction, notice, consent, waiver or other Act may be given before or after such record date, but only the Holders of record at the close of business on such record date shall be deemed to be Holders for the purposes of determining whether Holders
of the requisite proportion of Outstanding Notes have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other Act, and for that purpose the Outstanding Notes shall be computed as of such
record date; provided that no such authorization, agreement or consent by the Holders on such record date shall be deemed effective unless it shall become effective pursuant to the provisions of this Supplemental Indenture not later than
eleven months after the record date. Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Note shall bind every future Holder of the same Note and the Holder of every Note issued upon the
registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee, the Company in reliance thereon, whether or not notation of such action is made upon such Note.

 SECTION 1304. Notices, Etc., to Trustee, Company and Agent. 

Any request, demand, authorization, direction, notice, consent, waiver or Act of Holders or other document provided or permitted by this
Supplemental Indenture to be made upon, given or furnished to, or filed with, 
 (1) the Trustee by any Holder or by the
Company shall be sufficient for every purpose hereunder if made, given, furnished or filed in writing (which may be via facsimile) to or with the Trustee at Wells Fargo Bank, National Association, 150 East 42nd Street, 40th Floor, New York, NY 10017, Attention: Corporate Trust Services, Administrator — Aircastle Limited, or 

(2) the Company by the Trustee or by any Holder shall be sufficient for every purpose hereunder (unless otherwise herein
expressly provided) if made, given, furnished or delivered in writing and mailed, first-class postage prepaid, or delivered by recognized overnight courier, to the Company addressed to it at the address of its principal office specified in the first
paragraph, Attention: General Counsel, or at any other address previously furnished in writing to the Trustee by the Company. 
 All notices
and communications shall be deemed to have been duly given: at the time delivered by hand, if personally delivered; five calendar days after being deposited in the mail, postage prepaid, if mailed by first-class mail; when receipt acknowledged, if
faxed or delivered by PDF or other electronic transmission; and the next Business Day after timely delivery to the courier, if sent by overnight air courier guaranteeing next day delivery; provided that any notice or communication delivered
to the Trustee shall be deemed effective upon actual receipt thereof. 

  
 -68- 

 SECTION 1305. Notice to Holders; Waiver. 

Where this Supplemental Indenture provides for notice of any event to Holders by the Company or the Trustee, such notice shall be sufficiently
given (unless otherwise herein expressly provided) in accordance with the procedures of DTC or if in writing and mailed or e-mailed, first-class postage prepaid or by overnight air courier guaranteeing next
day delivery, to each Holder affected by such event, at his address as it appears in the Note Register, not later than the latest date, and not earlier than the earliest date, prescribed for the giving of such notice. In any case where notice to
Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. Notices given by publication shall be
deemed given on the first date on which publication is made and notices given by first-class mail, postage prepaid, shall be deemed given five calendar days after mailing. 

In case by reason of the suspension of or irregularities in regular mail service or by reason of any other cause, it shall be impracticable to
mail notice of any event to Holders when such notice is required to be given pursuant to any provision of this Supplemental Indenture, then any manner of giving such notice as shall be satisfactory to the Trustee shall be deemed to be a sufficient
giving of such notice for every purpose hereunder. 
 Where this Supplemental Indenture provides for notice in any manner, such notice may
be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be
a condition precedent to the validity of any action taken in reliance upon such waiver. 
 SECTION 1306. Effect of Headings and Table of
Contents. 
 The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the
construction hereof. 
 SECTION 1307. Successors and Assigns. 

All agreements of the Company in this Supplemental Indenture and the Notes will bind its successors. All agreements of the Trustee in this
Supplemental Indenture will bind its successors. All agreements of each Guarantor, if any, in this Supplemental Indenture will bind its successors. 

SECTION 1308. Separability Clause. 

In case any provision in this Supplemental Indenture or in the Notes shall be invalid, illegal or unenforceable, the validity, legality and
enforceability of the remaining provisions shall not in any way be affected or impaired thereby. 
 SECTION 1309. Benefits of
Indenture. 
 Nothing in this Supplemental Indenture or in the Notes, express or implied, shall give to any Person, other than the
parties hereto, any Paying Agent, any Notes Registrar and their successors hereunder, and the Holders, any benefit or any legal or equitable right, remedy or claim under this Supplemental Indenture. 

  
 -69- 

 SECTION 1310. Governing Law. 

This Supplemental Indenture, the Notes and any Note Guarantee shall be governed by and construed in accordance with the laws of the State of
New York. This Supplemental Indenture is subject to the provisions of the Trust Indenture Act that are referred to herein or are otherwise required to be part of this Supplemental Indenture and shall, to the extent applicable, be governed by such
provisions. 
 SECTION 1311. Communication by Holders of Notes with Other Holders of Notes. 

Holders may communicate pursuant to Trust Indenture Act Section 312(b) with other Holders with respect to their rights under this
Supplemental Indenture or the Notes. The Company, the Trustee, the Notes Registrar and anyone else shall have the protection of Trust Indenture Act Section 312(c). 

SECTION 1312. Legal Holidays. 

In any case where any Interest Payment Date, Redemption Date or Stated Maturity or Maturity of any Note shall not be a Business Day, then
(notwithstanding any other provision of this Supplemental Indenture or of the Notes) payment of principal (or premium, if any) or interest need not be made on such date, but may be made on the next succeeding Business Day with the same force and
effect as if made on the Interest Payment Date, Redemption Date, or at the Stated Maturity or Maturity; provided that no interest shall accrue for the period from and after such Interest Payment Date, Redemption Date, Stated Maturity or
Maturity, as the case may be. 
 SECTION 1313. No Personal Liability of Directors, Officers, Employees and Shareholders. 

No director, officer, employee, incorporator or shareholder of the Company or any Subsidiaries shall have any liability for any obligations of
the Company or any Subsidiary under the Notes, the Note Guarantees or this Supplemental Indenture or for any claim based on, in respect of, or by reason of such obligations or their creation. Each Holder by accepting a Note waives and releases all
such liability. The waiver and release are part of the consideration for issuance of the Notes and the Note Guarantees. 
 SECTION 1314.
Trust Indenture Act Controls. 
 If any provision of the Base Indenture (as it relates to the Notes) or this Supplemental Indenture
limits, qualifies or conflicts with another provision which is required to be included therein or herein by the TIA, the provision required by the TIA shall control. If any provision of the Base Indenture (as it relates to the Notes) or this
Supplemental Indenture modifies or excludes any provision of the TIA that may be so modified or excluded, the latter provision shall be deemed to apply to the Base Indenture (as it relates to the Notes) or this Supplemental Indenture, as the case
may be, as so modified or excluded, as the case may be. 
 SECTION 1315. Counterparts. 

This Supplemental Indenture may be executed in any number of counterparts, each of which shall be original; but such counterparts shall
together constitute but one and the same instrument. The exchange of copies of this Supplemental Indenture and of signature pages by facsimile or PDF transmission shall constitute effective execution and delivery of this Supplemental Indenture as to
the parties hereto and may be used in lieu of the original Supplemental Indenture and signature pages for all purposes.

The parties hereto acknowledge that in accordance with Section 326 of the USA Patriot Act the Trustee and Agents, like all financial
institutions and in order to help fight the funding of terrorism and money laundering, are required to obtain, verify, and record information that identifies each person or legal entity that establishes a relationship or opens an account. The
parties to this Supplemental Indenture agree that they will provide the Trustee and the Agents with such information as they may reasonably request in order to satisfy the requirements of the USA Patriot Act. 

SECTION 1317. Waiver of Jury Trial. 

EACH OF THE COMPANY AND THE TRUSTEE HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY
JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS SUPPLEMENTAL INDENTURE, THE NOTES OR THE TRANSACTION CONTEMPLATED HEREBY. 

SECTION 1318. Effective Indenture. 

This Supplemental Indenture modifies, amends, supplements and deletes certain terms contained the Base Indenture. The modifications,
amendments, supplements and deletions to the Base Indenture affected by this Supplemental Indenture shall be applicable only with respect to, and shall only govern the terms of, the Notes, except as otherwise provided herein, and shall not apply to
any other securities that may be issued under the Base Indenture unless a supplemental indenture with respect to such other securities specifically incorporates such changes, modifications and supplements.

	1.	 Principal and Interest. 

The Company will pay the principal of the 4.250% Senior Notes due 2026 (the “Notes”) on June 15, 2026. 

The Company promises to pay interest on the principal amount of this Note on each Interest Payment Date, as set forth below, at the rate of
4.250% per annum. 
 Interest will be payable semi-annually (to the Holders of record of the Notes (or any Predecessor Notes) at the close
of business on June 1 or December 1 immediately preceding the Interest Payment Date) on each Interest Payment Date, commencing December 15, 2019. 

Interest on this Note will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from
June 13, 2019; provided that, following the Issue Date, if there is no existing default in the payment of interest and if this Note is authenticated between a Regular Record Date referred to on the face hereof and the next succeeding
Interest Payment Date, interest shall accrue from such Interest Payment Date. Interest will be computed on the basis of a 360-day year of twelve 30-day months. 

The Company shall pay interest on overdue principal and premium, if any, and interest on overdue installments of interest, to the extent
lawful, at a rate per annum equal to the rate of interest applicable to the Notes. 
  

	2.	 Method of Payment. 

The Company will pay interest (except defaulted interest) on the principal amount of the Notes on each June 15 and December 15 to the
Persons who are Holders (as reflected in the Note Register at the close of business on June 1 and December 1 immediately preceding the Interest Payment Date), in each case, even if the Note is cancelled on registration of transfer or
registration of exchange after such Regular Record Date; provided that, with respect to the payment of principal, the Company will make payment to the Holder that surrenders this Note to any Paying Agent on or after June 15, 2026. 

The Company will pay principal (premium, if any) and interest in money of the United States that at the time of payment is legal tender for
payment of public and private debts. The principal of (and premium, if any) and interest on the Notes shall be payable at the office or agency of the Company maintained for such purpose in The City and State of New York or, at the option of the
Company, payment of interest may be made by check mailed to the Holders of the Notes at their respective addresses set forth in the Note Register of Holders; provided that all payments of principal, premium, if any, and interest, if any, with
respect to Notes represented by one or more Global Notes registered in the name of or held by Depositary or its nominee will be made by wire transfer of immediately available funds to the accounts specified by the Holder or Holders thereof. Until
otherwise designated by the Company, the Company’s office or agency in New York shall be the office of the Trustee maintained for such purpose. If a payment date is a date other than a Business Day at a place of payment, payment may be made at
that place on the next succeeding day that is a Business Day and no interest shall accrue for the intervening period. 

  
 A-1-4 

	3.	 Paying Agent and Note Registrar. 

Initially, the Trustee will act as Paying Agent and Note Registrar. The Company may change any Paying Agent or Note Registrar upon written
notice thereto. The Company may act as Paying Agent, Note Registrar or co-registrar. 
  

	4.	 Indenture; Limitations. 

The Company issued the Notes under that certain Seventh Supplemental Indenture dated as of June 13, 2019 (the “Supplemental
Indenture”), between the Company and Wells Fargo Bank, National Association, as trustee (the “Trustee”), to that certain Base Indenture dated as of December 5, 2013, between the Company and the Trustee (the “Base
Indenture” and, together with the Supplemental Indenture and any future supplemental indenture entered into thereunder, the “Indenture”). Capitalized terms herein are used as defined in the Indenture unless otherwise indicated. 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. The Notes are subject to all such terms, and Holders are referred to the Indenture and the Trust Indenture Act for
a statement of all such terms. To the extent permitted by applicable law, in the event of any inconsistency between the terms of this Note and the terms of the Indenture, the terms of the Indenture shall control. 

The Notes are senior unsecured obligations of the Company. The Indenture does not limit the aggregate principal amount of the Notes. 

 

	5.	 Redemption. 

Optional Redemption. Prior to April 15, 2026, the Company may, at any time and from time to time, redeem all or a part of the
Notes, upon not less than 15 nor more than 60 days’ prior notice mailed by first class mail to each Holder’s registered address, at a Redemption Price equal to the greater of (a) 100% of the principal amount of the Notes redeemed, plus
accrued and unpaid interest thereon to, but not including, the Redemption Date, and (b) the sum of the present values of 100% of the principal amount of the Notes being redeemed and the remaining scheduled payments of interest on the Notes from
the Redemption Date through April 15, 2026 (computed using a discount rate equal to the Treasury Rate as of such Redemption Date plus 25 basis points), plus accrued and unpaid interest to, but not including, the Redemption Date. 

On and after April 15, 2026, the Company may on any one or more occasions redeem all or a part of the Notes, upon not less than 15 nor
more than 60 days’ prior notice mailed by first class mail to each Holder’s registered address, at a Redemption Price equal to 100% of the aggregate principal amount thereof, plus accrued and unpaid interest thereon, if any, to, but not
including, the Redemption Date, subject to the right of Holders of record on the relevant Record Date to receive interest due on the relevant Interest Payment Date. 

The Company will be entitled, at its option, to redeem the Notes in whole if at any time it becomes obligated to pay additional amounts on the
Notes on the next Interest Payment Date with respect to the Notes, but only if its obligation results from a change in, or an amendment to, the laws or treaties (including any regulations or official rulings promulgated thereunder) of a Relevant Tax
Jurisdiction (or a political subdivision or taxing authority thereof or therein), or from a change in any official position regarding the interpretation, administration or application of those laws, treaties, regulations or official

  
 A-1-5 

 
rulings (including a change resulting from a holding, judgment or order by a court of competent jurisdiction), that becomes effective and is announced after the Issue Date (or, if the applicable
Relevant Tax Jurisdiction became a Relevant Tax Jurisdiction on a date after the Issue Date, such later date) and provided the Company cannot avoid the obligation after taking reasonable measures to do so. If the Company redeems the Notes in
these circumstances, it will do so at a Redemption Price equal to 100% of the principal amount of the Notes redeemed, plus accrued and unpaid interest, if any, and any other amounts due to the redemption date. 

If the Company becomes entitled to redeem the Notes in these circumstances, it may do so at any time on a redemption date of its choice.
However, the Company must give the Holders of the Notes being redeemed notice of the redemption not less than 15 days or more than 60 days before the redemption date and not more than 90 days before the next date on which it would be obligated to
pay additional amounts. In addition, the Company’s obligation to pay additional amounts must remain in effect when it gives the notice of redemption. Notice of the Company’s intent to redeem the Notes shall not be effective until such time
as it delivers to the Trustee both a certificate signed by two of its officers stating that the obligation to pay additional amounts cannot be avoided by taking reasonable measures and an opinion of independent legal counsel or an independent
auditor stating that the Company is obligated to pay additional amounts because of an amendment to or change in law, treaties or position as described in the preceding paragraph. 

In addition to the Company’s rights to redeem Notes as set forth above, the Company may at any time purchase Notes in open-market
transactions, tender offers, privately negotiated purchases or otherwise. 
  

	6.	 Repurchase upon a Change in Control. 

Upon the occurrence of a Change in Control Triggering Event, the Holders of the Notes will have the right to require that the Company purchase
such Holder’s outstanding Notes, in whole or in part, at a purchase price of 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to, but not including, the date of purchase. 

 

	7.	 Denominations; Transfer; Exchange. 

The Notes are in registered form without coupons, in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. A
Holder may register the transfer or exchange of Notes in accordance with the Indenture. The Note Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes and fees required by
law or permitted by the Indenture. The Note Registrar need not register the transfer or exchange of any Notes (i) during a period beginning at the opening of business 15 days before the mailing of a notice of redemption of Notes for redemption
under Section 1105 of the Indenture and ending at the close of business on the day of such mailing, (ii) selected for redemption (except the unredeemed portion of any Note being redeemed in part) and (iii) between a Record Date and
the next succeeding Interest Payment Date. 
  

	8.	 Persons Deemed Owners. 

A registered Holder may be treated as the owner of a Note for all purposes. 

  
 A-1-6 

	9.	 Unclaimed Money. 

If money for the payment of principal (premium, if any) or interest remains unclaimed for two years, the Trustee and the Paying Agent will pay
the money back to the Company at its written request. After that, Holders entitled to the money must look to the Company for payment, unless an abandoned property law designates another Person, and all liability of the Trustee and such Paying Agent
with respect to such money shall cease. 
  

	10.	 Discharge and Defeasance Prior to Redemption or Maturity. 

Subject to certain conditions, the Company at any time shall be entitled to terminate some or all of its obligations under the Notes and the
Indenture if the Company deposits with the Trustee money or Government Securities for the payment of principal and interest on the Notes to redemption or maturity, as the case may be. 

 

	11.	 Amendment; Supplement; Waiver. 

Subject to certain exceptions, the Base Indenture (as it refers to the Notes), the Supplemental Indenture or the Notes may be amended or
supplemented with the consent of the Holders of at least a majority in aggregate principal amount of the Outstanding Notes, and any existing Default or compliance with any provision may be waived with the consent of the Holders of a majority in
aggregate principal amount of the Outstanding Notes. Without notice to or the consent of any Holder, the parties thereto may amend or supplement the Indenture or the Notes to, among other things, cure any ambiguity, defect or inconsistency and make
any change that does not adversely affect the rights of any Holder. 
  

	12.	 Restrictive Covenants. 

The Indenture contains certain covenants, including, without limitation, covenants with respect to the following matters: (i) Liens; (ii)
Purchase of Notes upon a Change in Control; (iii) Note Guarantees; and (iv) Amalgamation, Merger, Consolidation or Sale of all or Substantially all Assets. 
  

	13.	 Successor Persons. 

When a successor Person or other entity assumes all the obligations of its predecessor under the Notes and the Indenture, the predecessor
Person will be released from those obligations. 
  

	14.	 Remedies for Events of Default. 

If an Event of Default, as defined in the Indenture, occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount
of the Outstanding Notes may declare all the Notes to be immediately due and payable. If a bankruptcy or insolvency default with respect to the Company or any of its Significant Subsidiaries occurs and is continuing, the Notes automatically become
immediately due and payable. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee may require indemnity reasonably satisfactory to it before it enforces the Indenture or the Notes. Subject to certain
limitations, Holders of at least a majority in aggregate principal amount of the Outstanding Notes may direct the Trustee in its exercise of any trust or power. 

  
 A-1-7 

	15.	 Guarantees. 

If the Notes are guaranteed, the Company’s obligations under the Notes are fully, irrevocably and unconditionally guaranteed on a senior
basis, to the extent set forth in the Indenture, by each of the Guarantors. 
  

	16.	 Trustee Dealings with Company. 

The Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may make loans to,
accept deposits from, perform services for, and otherwise deal with, the Company and its Affiliates as if it were not the Trustee. 
  

	17.	 Authentication. 

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

 

	18.	 Abbreviations. 

Customary abbreviations may be used in the name of a Holder 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).

 SUPPLEMENTAL INDENTURE NO. 1 (the “Supplemental Indenture”), dated
as of June 13, 2019, between American Tower Corporation, a Delaware corporation (the “Company”), and U.S. Bank National Association, a national banking association, as trustee (the “Trustee”). 

WITNESSETH THAT: 

WHEREAS, the Company and the Trustee have executed and delivered a base indenture, dated as of June 4, 2019 (the “Base
Indenture,” and, together with this Supplemental Indenture, as amended, supplemented or otherwise modified from time to time, the “Indenture”) to provide for the future issuance of the Company’s senior debt securities
to be issued from time to time in one or more series; 
 WHEREAS, pursuant to the terms of the Base Indenture, the Company
desires to provide for the establishment of two series of its Securities, to be titled as its “2.950% Senior Notes due 2025 (the “2025 Notes”) and “3.800% Senior Notes due 2029” (the “2029 Notes”) the
form and substance of such Securities and the terms, provisions and conditions thereof to be set forth as provided in the Indenture; and 

WHEREAS, all acts and requirements necessary to make this Supplemental Indenture, when executed and delivered by the parties hereto, the
legal, valid and binding obligation of the Company, in accordance with its terms, have been done. 
 NOW, THEREFORE: 

Each party agrees as follows for the benefit of the other party and for the equal and ratable benefit of the Holders of the Securities. 

ARTICLE I DEFINITIONS AND INCORPORATION BY REFERENCE 

Section 1.01. DEFINITIONS. 

Capitalized terms used herein without definition shall have the respective meanings ascribed to them in the Base Indenture. The following
definitions supplement, and, to the extent inconsistent with, replace the definitions in Article I of the Base Indenture: 

“Additional Security Board Resolution” means resolutions duly adopted by the Board of Directors of the Company and delivered
to the Trustee in an Officers’ Certificate providing for issuance of Additional Securities. 
 “Additional Security
Supplemental Indenture” means a supplement to this Indenture duly executed and delivered by the Company and the Trustee pursuant to Article 7 of the Base Indenture. 

“Additional Securities” means the Company’s Securities originally issued hereunder after the Issue Date pursuant to
Section 2.13 hereof, except for Securities authenticated and delivered upon registration of, transfer of, or in exchange for, or in lieu of other Securities pursuant to Section 3.07, 3.09, 7.05 or 9.06 of the Base Indenture, or 4.01(b)
hereof, as specified in the relevant Additional Security Board Resolutions or Additional Security Supplemental Indenture issued therefor in accordance with this Indenture. 

“Adjusted EBITDA” means, for the 12-month period preceding the calculation date, for the Company and its Subsidiaries on a
consolidated basis in accordance with GAAP, the sum of (a) Net Income, plus (b) to the extent deducted in determining Net Income, the sum of (i) Interest Expense, (ii) income tax expense, including, without limitation, taxes paid
or accrued based on income, profits or capital, including state, franchise and similar taxes and foreign withholding taxes, (iii) depreciation and amortization (including, without limitation, amortization of goodwill and other intangible
assets), (iv) extraordinary losses and non-recurring non-cash charges and expenses, (v) all other non-cash charges, expenses and interest (including, without limitation, any non-cash losses in respect of Commodity Agreements, Currency
Agreements or Interest Rate Agreements, non-cash impairment charges, non-cash valuation charges for stock option grants or vesting of restricted stock awards or any other non-cash compensation charges, and losses from the early extinguishment of
Indebtedness) and (vi) non-recurring charges and 

 
expenses, restructuring charges, transaction expenses (including, without limitation, transaction expenses incurred in connection with any merger or acquisition) and underwriters’ fees or
discounts, and severance and retention payments in connection with any merger or acquisition, in each case for such period, less extraordinary gains and cash payments (not otherwise deducted in determining net income) made during such period with
respect to non-cash charges that were added back in a prior period; provided, however, (I) with respect to any Person that became a Subsidiary, or was merged with or consolidated into the Company or any Subsidiary, during such
period, or any acquisition by the Company or any Subsidiary of the assets of any Person during such period, “Adjusted EBITDA” shall, at the option of the Company in respect of any or all of the foregoing, also include the Adjusted EBITDA
of such Person or attributable to such assets, as applicable, during such period as if such acquisition, merger or consolidation had occurred on the first day of such period and (II) with respect to any Person that has ceased to be a Subsidiary
during such period, or any material assets of the Company or any Subsidiary sold or otherwise disposed of by the Company or any Subsidiary during such period, “Adjusted EBITDA” shall exclude the Adjusted EBITDA of such Person or
attributable to such assets, as applicable, during such period as if such sale or disposition of such Subsidiary or such assets had occurred on the first day of such period. 

“Adjusted Treasury Rate” means, with respect to any redemption date: 

(1) the yield that represents the average for the immediately preceding week, appearing in the most recently published statistical release
designated “H.15” or any successor publication which is published weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded United States 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 Life, yields for the two published maturities
most closely corresponding to the Comparable Treasury Issue shall be determined and the Adjusted Treasury Rate shall be interpolated or extrapolated from such yields on a straight line basis, rounding to the nearest month); or 

(2) 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 Adjusted Treasury Rate shall be calculated on the third Business Day preceding the
redemption date. 
 “Beneficial Owner” has the meaning assigned to such term in Rule 13d-3 and Rule 13d-5 under the
Exchange Act, except that in calculating the beneficial ownership of any particular “person” (as that term is used in Section 13(d)(3) of the Exchange Act), such “person” will be deemed to have beneficial ownership of all
securities that such “person” has the right to acquire by conversion or exercise of other securities, whether such right is currently exercisable or is exercisable only upon the occurrence of a subsequent condition. The terms
“Beneficially Owns” and “Beneficially Owned” have a corresponding meaning. 
 “Capital Lease
Obligation” means, at the time any determination is to be made, the amount of the liability in respect of a capital lease that would at that time be required to be capitalized on a balance sheet in accordance with GAAP. 

“Capital Stock” means: 

(1) in the case of a corporation, corporate stock; 

(2) in the case of an association or business entity, any and all shares, interests, participations, rights or other equivalents (however
designated) of corporate stock; 
 (3) in the case of a partnership or limited liability company, partnership or membership interests
(whether general or limited); and

from time to time constitutes and will constitute a senior unsecured obligation of the Company, ranking pari passu in right of payment with each other and with all other existing and future senior unsecured obligations of the Company. Unless
the context otherwise requires, the 2025 Notes shall be considered collectively to be a single class for all purposes of this Indenture and the 2029 Notes shall be considered collectively to be a single class for all purposes of this Indenture,
including without limitation waivers, amendments, redemptions and Change of Control Offers. 
 Section 2.13. ADDITIONAL
SECURITIES. 
 The Company may, from time to time, subject to compliance with any other applicable provisions of this
Indenture, without the consent of the Holders, create and issue pursuant to this Indenture additional securities (“Additional Securities”) having terms and conditions identical to those of the Securities, except that Additional
Securities: 

  
 12 

 (i) may have a different issue date from the Securities; 

(ii) may have a different amount of interest payable on the first Interest Payment Date after issuance than is payable on other Securities; and

 (iii) may have terms specified in the Additional Securities Board Resolution or Additional Securities Supplemental Indenture for such
Additional Securities making appropriate adjustments to Article II and Exhibit A (and related definitions) applicable to such Additional Securities in order to conform to and ensure compliance with the Securities Act (or other applicable securities
laws) and any other agreement applicable to such Additional Securities, which are not adverse in any material respect to the Holder of any Securities (other than such Additional Securities); 

provided, that no adjustment pursuant to this Section 2.13 shall cause such Additional Securities to constitute, as determined
pursuant to an Opinion of Counsel, a different class of securities than the Original Securities for U.S. federal income tax purposes. The Original Securities and any Additional Securities would rank equally and ratably and would be treated as a
single series of debt securities for all purposes under the Indenture. 
 ARTICLE III OPTIONAL REDEMPTION; MANDATORY REDEMPTION 

Section 3.01. NOTICE TO TRUSTEE. 

If the Company elects to redeem Securities pursuant to the optional redemption provisions of Section 3.02 hereof, it shall furnish to the
Trustee, at least 15 days but not more than 60 days before a redemption date, an Officers’ Certificate setting forth (1) the redemption date, (2) the principal amount of the 2025 Notes and/or the 2029 Notes, as applicable, to be

(1) 100% of the principal amount of the 2025 Notes to be redeemed then outstanding; and 

(2) as determined by an Independent Investment Banker, the sum of the present values of the remaining scheduled payments of
principal and interest on the 2025 Notes to be redeemed that would be due if such notes matured on the First Par Call Date (not including any portion of such payments of interest accrued to the date of redemption) discounted to the redemption date
on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate for the 2025 Notes, plus 20 basis points; 

plus, in either of the above cases, accrued and unpaid interest to the date of redemption on the 2025 Notes to be redeemed. 

(b) The 2029 Notes are redeemable at the Company’s election, in whole or in part, at any time and from time to time. If the Company
redeems the 2029 Notes prior to May 15, 2029 (three months prior to their maturity date), it will pay a redemption price equal to the greater of: 

(1) 100% of the principal amount of the 2029 Notes to be redeemed then outstanding; and 

(2) as determined by an Independent Investment Banker, the sum of the present values of the remaining scheduled payments of
principal and interest on the securities to be redeemed that would be due if such notes matured on the First Par Call Date (not including any portion of such payments of interest accrued to the date of redemption) discounted to the redemption date
on a semiannual basis (assuming a 

  
 13 

 
360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate for such securities, plus 30 basis points; 

plus, in either of the above cases, accrued and unpaid interest to the date of redemption on the securities to be redeemed. 

(c) If the Company redeems the 2025 Notes on or after December 15, 2024 (one month prior to their maturity date), it will pay a
redemption price equal to 100% of the principal amount of the 2025 Notes to be redeemed plus accrued interest to the redemption date. If the Company redeems the 2029 Notes on or after May 15, 2029 (three months prior to their maturity date), it
will pay a redemption price equal to 100% of the principal amount of the 2029 Notes to be redeemed plus accrued interest to the redemption date. 

(d) If the optional redemption date is on or after a Regular Record Date and on or before the related Interest Payment Date, the accrued and
unpaid interest, if any, will be paid to the person in whose name the security is registered at the close of business on such Regular Record Date. 

(e) Any redemption pursuant to this Section 3.02 shall be made pursuant to Section 3.01 hereof and the provisions of Article 9 of the
Base Indenture. 
 Section 3.03. MANDATORY REDEMPTION. 

The Company shall not be required to make mandatory redemption or sinking fund payments with respect to the Securities. 

ARTICLE IV COVENANTS 

Section 4.01. ADDITIONAL COVENANTS. 

In addition to those Covenants set forth in Article 4 of the Base Indenture, the Company shall comply with the following covenants: 

(a) Limitation on Liens. 

The Company shall not, and shall not permit any of its Subsidiaries to, allow any Lien on any of the Company’s or its Subsidiaries’
property or assets (which includes Capital Stock) securing Indebtedness, unless the Lien secures the Securities equally and ratably with, or prior to, any other Indebtedness secured by such Lien, so long as such other Indebtedness is so secured,
other than Permitted Liens. 
 Notwithstanding the foregoing, the Company may, and may permit any of its Subsidiaries to, incur Liens
securing Indebtedness without equally and ratably securing the Securities if, after giving effect to the incurrence of such Liens, the aggregate amount (without duplication) of the Indebtedness secured by Liens (other than Permitted Liens) on the
property or assets (which includes Capital Stock) of the Company and its Subsidiaries shall not exceed the Permitted Amount at the time of the incurrence of such Liens (it being understood that Liens securing SpectraSite ABS Facility shall be deemed
to be incurred pursuant to this paragraph). For the avoidance of doubt, “incur” means to create, incur, issue, assume, guarantee or otherwise become directly liable, contingently or otherwise. 

(b) Repurchase of the Securities Upon a Change of Control Triggering Event. 

Upon the occurrence of a Change of Control Triggering Event, each Holder of Securities shall have the right to require the Company to
repurchase all or any part, equal to $2,000 or an integral multiple of $1,000 thereafter, of that Holder’s Securities, provided that any unpurchased portion of the Securities shall equal $2,000 or an integral multiple of $1,000
thereafter, pursuant to an offer (the “Change of Control Offer”) on the terms set forth in this Indenture at an offer price in cash equal to 101% of the aggregate principal amount of Securities repurchased plus accrued and unpaid
interest on the Securities up to but excluding the applicable date of repurchase 

  
 14 

 
(the “Change of Control Payment”). Within 30 days following any Change of Control Triggering Event, if the Company had not, prior to the Change of Control Triggering Event, sent
a redemption notice for all the Securities in connection with an optional redemption permitted by Section 3.02 hereof, the Company shall mail or caused to be mailed a notice to each registered Holder briefly describing the transaction or
transactions that constitute a Change of Control Triggering Event and offering to repurchase Securities on the date specified in such notice (the “Change of Control Payment Date”), which date shall be no earlier than 30 days and no
later than 60 days from the date the notice is mailed, pursuant to the procedures required by this Indenture and described in such notice. 

The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder
to the extent such laws and regulations are applicable to any Change of Control Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 4.01(b), the Company shall comply with
the applicable securities laws and regulations and will not be deemed to have breached its obligations under the provisions of this Section 4.01(b) by virtue of such conflict. 

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

(1) accept for payment all Securities or portions thereof properly tendered pursuant to the Change of Control Offer; 

(2) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Securities or portions
thereof properly tendered; and 
 (3) deliver or cause to be delivered to the Trustee the Securities so accepted together
with an Officers’ Certificate stating the aggregate principal amount of Securities or portions thereof being purchased by the Company. 

The Paying Agent will promptly mail to each registered Holder of Securities so tendered the Change of Control Payment for such Securities, and
the Trustee will promptly authenticate and mail (at the Company’s expense), or cause to be transferred by book entry, to each Holder a new Security equal in principal amount to any unpurchased portion of the Securities surrendered, if any;
provided that each such new Security shall be in a principal amount of $2,000 or an integral multiple of $1,000 thereafter. Any Security so accepted for payment shall cease to accrue interest on and after the Change of Control Payment Date.

 This Section 4.01(b) shall be applicable, except as described in this Section 4.01(b), regardless of whether or not any other
provisions of this Indenture are applicable. 
 Notwithstanding the foregoing, the Company shall not be required to make a Change of Control
Offer upon a Change of Control Triggering Event if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 4.01(b) applicable to a Change of Control
Offer made by the Company and purchases all Securities properly tendered and not withdrawn under the Change of Control Offer. 
 The Company
may make a Change of Control Offer in advance of a Change of Control Triggering Event, and conditional upon the occurrence of such Change of Control Triggering Event, if a definitive agreement is in place for the Change of Control Triggering Event
at the time of making the Change of Control Offer.

 [REVERSE OF SECURITY] 

AMERICAN TOWER CORPORATION 

2.950% Senior Notes due 2025 

(the “Securities”) 

1. Interest. American Tower Corporation, a Delaware corporation (the
“Company”), promises to pay interest on the principal amount of this Security at the rate per annum shown above. The Company will pay interest, payable semi-annually in arrears, on January 15 and
July 15 of each year, with the first payment to be made on January 15, 2020. Interest on the Securities will accrue on the principal amount from, and including, the most recent date to which interest has been paid or provided for or, if no
interest has been paid, from, and including June 13, 2019, in each case to, but excluding, the next Interest Payment Date or the Stated Maturity for the payment of principal on the Securities, as the case may be; provided that if there
is no existing Default in the payment of interest, the Company shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and premium, if any, from time to time on demand at a rate that is
1% per annum in excess of the rate then in effect; it shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace periods) from
time to time on demand at the same rate to the extent lawful. Interest shall be computed on the basis of a 360-day year of twelve 30-day months.  

2. Maturity. The Securities will mature on January 15, 2025. 

3. Method of Payment. Except as provided in the Indenture (as defined below), the Company shall pay interest on the
Securities to the persons who are Holders of record of Securities at the close of business on the Regular Record Date set forth on the face of this Security next preceding the applicable Interest Payment Date. Holders must surrender Securities to a
Paying Agent to collect the principal amount. The Company shall pay, in money of the United States that at the time of payment is legal tender for payment of public and private debts, all amounts due in cash with respect to the Securities, which
amounts shall be paid (A) in the case this Security is a Global Security, by wire transfer of immediately available funds to the account designated by the Depository for the Securities or its nominee; and (B) in the case this Security is a
Physical Security, by mailing a check to the address of the relevant Holder set forth in the Security Register for the Securities. The Company shall pay, in cash, interest on any overdue amount (including, to the extent permitted by applicable law,
overdue interest) at the rate borne by the Securities. 
 4. Paying Agent and Registrar. Initially, U.S. Bank National
Association (the “Trustee”) shall act as Paying Agent and Registrar. The Company may change any Paying Agent or Registrar upon prior written notice to the Trustee. The Company or any of its Subsidiaries may act in any such capacity.

 5. Indenture. The Company issued the Securities under an indenture dated as of June 4, 2019 (as amended, supplemented or
otherwise modified from time to time prior to the date hereof, the “Base Indenture”) between the Company and the Trustee, as amended, supplemented or otherwise modified by the Supplemental Indenture No. 1 (the
“Supplemental Indenture”), dated as of June 13, 2019, between the Company and the Trustee (the Base Indenture, as amended, supplemented or otherwise modified by the Supplemental Indenture, the “Indenture”). The
terms of the Securities 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. Code §§ 77aaa-77bbbb) (the “TIA”) as amended and in effect from
time to time. The Securities are subject to all such terms, and Holders are referred to the Indenture and the TIA for a statement of such terms. To the extent any provision of this Security conflicts with the express provisions of the Indenture, the
provisions of the Indenture shall govern and be controlling. The Securities are general unsecured senior obligations of the Company. The Original Securities are limited to $650,000,000 aggregate principal amount, except as otherwise provided in the
Indenture (except for Securities issued in substitution for destroyed, mutilated, lost or stolen Securities). Subject to the conditions set forth in the Indenture and without the consent of the Holders, the Company may issue Additional Securities.
All Securities, including any Additional Securities, shall be treated as a single class of securities under the Indenture. Terms used herein without definition and that are defined in the Indenture have the meanings assigned to them in the
Indenture. 

  
 A-1-4 

 6. Optional Redemption. The Securities are redeemable at the Company’s election, in whole
or in part, at any time and from time to time. If the Company redeems the Securities prior to the First Par Call Date, the Company will pay a redemption price equal to the greater of: 

(1) 100% of the principal amount of the Securities to be redeemed then outstanding; and 

(2) as determined by an Independent Investment Banker, the sum of the present values of the remaining scheduled payments of principal and
interest on the Securities to be redeemed that would be due if the Securities matured on the First Par Call Date (not including any portion of such payments of interest accrued to the date of redemption) discounted to the redemption date on a
semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate, plus 20 basis points; 
 plus, in either of the
above cases, accrued and unpaid interest to the date of redemption on the Securities to be redeemed. 
 If the Company redeems the
Securities on or after the First Par Call Date, the Company will pay a redemption price equal to 100% of the principal amount of the Securities to be redeemed plus accrued interest to the redemption date. 

If the Company selects a redemption date that is on or after a Regular Record Date and on or before the related Interest Payment Date, the
accrued and unpaid interest, if any, shall be paid to the person in whose name the Security is registered at the close of business on such Regular Record Date. 

The Company shall mail or cause to be mailed a notice of redemption at least 15 days, but not more than 60 days, before the redemption date to
each Holder of the Securities to be redeemed at its registered address, except that redemption notices may be mailed more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Securities or a
satisfaction and discharge of the Indenture. Notices of redemption may not be conditional. 
 Unless the Company defaults in payment of the
redemption price, on and after the redemption date, interest shall cease to accrue on the Securities or portions thereof called for redemption. Securities called for redemption become due on the date fixed for redemption. 

For purposes of the foregoing, the following terms have the following meanings: 

“Adjusted Treasury Rate” means, with respect to any redemption date: 

(1) the yield that represents the average for the immediately preceding week, appearing in the most recently published
statistical release designated “H.15” or any successor publication which is published weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded United States Treasury securities adjusted
to constant maturity under the caption “Treasury Constant Maturities,” for the maturity corresponding to the Comparable Treasury Issue (as defined below) (if no maturity is within three months before or after the Remaining Life (as defined
below), yields for the two published maturities most closely corresponding to the Comparable Treasury Issue shall be determined and the Adjusted Treasury Rate shall be interpolated or extrapolated from such yields on a straight line basis, rounding
to the nearest month); or 
 (2) 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 (as defined below) for such redemption date. 
 The Adjusted Treasury Rate shall be
calculated on the third Business Day preceding the redemption date. 

  
 A-1-5 

 “Comparable Treasury Issue” means the United States Treasury security
selected by an Independent Investment Banker (as defined below) as having a maturity comparable to the remaining term of the Securities (the “Remaining Life”) that would be utilized, at the time of selection and in accordance with
customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the Remaining Life of the Securities. 

“Comparable Treasury Price” means, for any redemption date, (1) the average of four Reference Treasury Dealer Quotations
(as defined below) for such redemption date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (2) if the Independent Investment Banker obtains fewer than four such Reference Treasury Dealer Quotations, the average
of all such quotations. 
 “First Par Call Date” means December 15, 2024. 

“Independent Investment Banker” means one of the Reference Treasury Dealers appointed by the Company. 

“Reference Treasury Dealer” means any of the primary U.S. Government securities dealers in New York City. 

“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. 
 7. No Mandatory Redemption.
The Company shall not be required to make mandatory redemption payments with respect to the Securities. 
 8. Repurchase
at Option of Holder. Upon the occurrence of a Change of Control Triggering Event, and subject to certain conditions set forth in the Indenture, the Company shall be required to offer to purchase all of the outstanding Securities at a purchase
price equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, thereon to the date of repurchase. 

9. Notice of Redemption. Notice of redemption shall be mailed at least 15 days but not more than 60 days before the redemption
date to each Holder whose Securities are to be redeemed at its registered address, except that redemption notices may be mailed more than 60 days prior to a redemption date if the notice is issued in connection with Article 10 or Article 11 of the
Base Indenture. Securities in denominations larger than $2,000 may be redeemed in part but only in whole multiples of $1,000, unless all of the Securities held by a Holder are to be redeemed. Unless the Company defaults in payment of the redemption
price, on and after the redemption date interest shall cease to accrue on Securities or portions thereof called for redemption. 

10. Denominations, Transfer, Exchange. The Securities are in registered form, without coupons, in denominations of $2,000
principal amount and integral multiples of $1,000 principal amount. The transfer of Securities may be registered and Securities may be exchanged as provided in the Indenture. The Registrar may require a Holder, among other things, to furnish
appropriate endorsements and transfer documents. No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or similar governmental charge that may be
imposed in connection with certain transfers or exchanges. The Company shall not be required to register the transfer of or exchange any Security selected for redemption, except for the unredeemed portion of any Security being redeemed in part.
Also, the Company need not exchange or register the transfer of any Securities for a period of 15 days next preceding the first mailing of notice of redemption of Securities to be redeemed. 

11. Persons Deemed Owners. The registered Holder of a Security shall be treated as the owner of such Security for all
purposes. 

  
 A-1-6 

 12. Merger or Consolidation. The Company shall not consolidate with or
merge with or into, or sell, transfer, lease, convey or otherwise dispose of all or substantially all of its property or assets to, another Person (including pursuant to a statutory arrangement), whether in a single transaction or series of related
transactions, unless it complies with Article 8 of the Base Indenture. 
 13. Amendments, Supplements and
Waivers. The Indenture or the Securities may be amended or supplemented as provided in the Indenture. 

14. Defaults and Remedies. The Events of Default relating to the Securities are defined in Section 5.01 of the Base
Indenture. If any Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the then outstanding Securities may declare the principal, premium, if any, interest and any other monetary obligations on
all the then outstanding Securities to be due and payable immediately. Notwithstanding the foregoing, in the case of an Event of Default arising from certain events of bankruptcy or insolvency, all outstanding Securities shall become due and payable
immediately without further action or notice. 
 Holders may not enforce the Indenture or the Securities except as provided in the
Indenture. Subject to certain limitations, Holders of a majority in aggregate principal amount of the then outstanding Securities may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of the Securities
notice of any continuing Default (except a Default relating to the payment of principal, premium, if any, or interest) if it determines that withholding notice is in their interest. The Holders of a majority in aggregate principal amount of the
Securities then outstanding by notice to the Trustee may on behalf of the Holders of all of the Securities waive any existing Default and its consequences under the Indenture except a continuing Default in payment of the principal of, premium, if
any, or interest, if any, on, any of the Securities held by a non-consenting Holder. The Company is required to deliver to the Trustee annually a statement regarding compliance with the Indenture, and the Company is required upon becoming aware of
any Default or Event of Default, to deliver to the Trustee a statement specifying such Default or Event of Default. 

15. Trustee Dealings with the Company. The Trustee, in its individual or any other capacity, may make loans to, accept
deposits from, and perform services for the Company or its affiliates, and may otherwise deal with the Company or its affiliates, as if it were not the Trustee. 

16. No Recourse Against Others. A director, officer, employee, incorporator or stockholder, of the Company, as such, shall
not have any liability for any obligations of the Company under the Securities or the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting a Security waives and releases
all such liability. The waiver and release are part of the consideration for the issuance of the Securities. 

17. Authentication. This Security shall not be valid until authenticated by the manual signature of the Trustee or an
authenticating agent in accordance with the Indenture. 
 18. Abbreviations. Customary abbreviations may be used
in the name of a Holder 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). 
 19. CUSIP and ISIN Numbers. Pursuant to a recommendation promulgated by the Committee on Uniform Security
Identification Procedures, the Company has caused CUSIP and ISIN numbers to be printed on the Securities and the Trustee may use CUSIP and ISIN numbers in notices of redemption as a convenience to Holders. No representation is made as to the
accuracy of such numbers either as printed on the Securities or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon. 

THE COMPANY SHALL FURNISH TO ANY HOLDER UPON WRITTEN REQUEST AND WITHOUT CHARGE A COPY OF THE BASE INDENTURE OR THE SUPPLEMENTAL INDENTURE.

 [REVERSE OF SECURITY] 

AMERICAN TOWER CORPORATION 

3.800% Senior Notes due 2029 

(the “Securities”) 

1. Interest. American Tower Corporation, a Delaware corporation (the
“Company”), promises to pay interest on the principal amount of this Security at the rate per annum shown above. The Company will pay interest, payable semi-annually in arrears, on February 15 and
August 15 of each year, with the first payment to be made on February 15, 2020. Interest on the Securities will accrue on the principal amount from, and including, the most recent date to which interest has been paid or provided for or, if
no interest has been paid, from, and including, June 13, 2019, in each case to, but excluding, the next Interest Payment Date or the Stated Maturity for the payment of principal on the Securities, as the case may be; provided that if
there is no existing Default in the payment of interest, the Company shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and premium, if any, from time to time on demand at a rate
that is 1% per annum in excess of the rate then in effect; it shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace periods)
from time to time on demand at the same rate to the extent lawful. Interest shall be computed on the basis of a 360-day year of twelve 30-day months.  

2. Maturity. The Securities will mature on August 15, 2029. 

3. Method of Payment. Except as provided in the Indenture (as defined below), the Company shall pay interest on the
Securities to the persons who are Holders of record of Securities at the close of business on the Regular Record Date set forth on the face of this Security next preceding the applicable Interest Payment Date. Holders must surrender Securities to a
Paying Agent to collect the principal amount. The Company shall pay, in money of the United States that at the time of payment is legal tender for payment of public and private debts, all amounts due in cash with respect to the Securities, which
amounts shall be paid (A) in the case this Security is a Global Security, by wire transfer of immediately available funds to the account designated by the Depository for the Securities or its nominee; and (B) in the case this Security is a
Physical Security, by mailing a check to the address of the relevant Holder set forth in the Security Register for the Securities. The Company shall pay, in cash, interest on any overdue amount (including, to the extent permitted by applicable law,
overdue interest) at the rate borne by the Securities. 
 4. Paying Agent and Registrar. Initially, U.S. Bank National
Association (the “Trustee”) shall act as Paying Agent and Registrar. The Company may change any Paying Agent or Registrar upon prior written notice to the Trustee. The Company or any of its Subsidiaries may act in any such capacity.

 5. Indenture. The Company issued the Securities under an indenture dated as of June 4, 2019 (as amended, supplemented or
otherwise modified from time to time prior to the date hereof, the “Base Indenture”) between the Company and the Trustee, as amended, supplemented or otherwise modified by the Supplemental Indenture No. 1 (the
“Supplemental Indenture”), dated as of June 13, 2019, between the Company and the Trustee (the Base Indenture, as amended, supplemented or otherwise modified by the Supplemental Indenture, the “Indenture”). The
terms of the Securities 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. Code §§ 77aaa-77bbbb) (the “TIA”) as amended and in effect from
time to time. The Securities are subject to all such terms, and Holders are referred to the Indenture and the TIA for a statement of such terms. To the extent any provision of this Security conflicts with the express provisions of the Indenture, the
provisions of the Indenture shall govern and be controlling. The Securities are general unsecured senior obligations of the Company. The Original Securities are limited to $1,650,000,000 aggregate principal amount, except as otherwise provided in
the Indenture (except for Securities issued in substitution for destroyed, mutilated, lost or stolen Securities). Subject to the conditions set forth in the Indenture and without the consent of the Holders, the Company may issue Additional
Securities. All Securities, including any Additional Securities, shall be treated as a single class of securities under the Indenture. Terms used herein without definition and that are defined in the Indenture have the meanings assigned to them in
the Indenture. 

  
 A-2-4 

 6. Optional Redemption. The Securities are redeemable at the
Company’s election, in whole or in part, at any time and from time to time. If the Company redeems the Securities prior to the First Par Call Date, the Company will pay a redemption price equal to the greater of: 

(1) 100% of the principal amount of the Securities to be redeemed then outstanding; and 

(2) as determined by an Independent Investment Banker, the sum of the present values of the remaining scheduled payments of principal and
interest on the Securities to be redeemed that would be due if such Securities matured on the First Par Call Date (not including any portion of such payments of interest accrued to the date of redemption) discounted to the redemption date on a
semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate, plus 30 basis points; 
 plus, in either of the
above cases, accrued and unpaid interest to the date of redemption on the Securities to be redeemed. 
 If the Company redeems the
Securities on or after the First Par Call Date, the Company will pay a redemption price equal to 100% of the principal amount of the Securities to be redeemed plus accrued interest to the redemption date. 

If the Company selects a redemption date that is on or after a Regular Record Date and on or before the related Interest Payment Date, the
accrued and unpaid interest, if any, shall be paid to the person in whose name the Security is registered at the close of business on such Regular Record Date. 

The Company shall mail or cause to be mailed a notice of redemption at least 15 days, but not more than 60 days, before the redemption date to
each Holder of the Securities to be redeemed at its registered address, except that redemption notices may be mailed more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Securities or a
satisfaction and discharge of the Indenture. Notices of redemption may not be conditional. 
 Unless the Company defaults in payment of the
redemption price, on and after the redemption date, interest shall cease to accrue on the Securities or portions thereof called for redemption. Securities called for redemption become due on the date fixed for redemption. 

For purposes of the foregoing, the following terms have the following meanings: 

“Adjusted Treasury Rate” means, with respect to any redemption date: 

(1) the yield that represents the average for the immediately preceding week, appearing in the most recently published
statistical release designated “H.15” or any successor publication which is published weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded United States Treasury securities adjusted
to constant maturity under the caption “Treasury Constant Maturities,” for the maturity corresponding to the Comparable Treasury Issue (as defined below) (if no maturity is within three months before or after the Remaining Life (as defined
below), yields for the two published maturities most closely corresponding to the Comparable Treasury Issue shall be determined and the Adjusted Treasury Rate shall be interpolated or extrapolated from such yields on a straight line basis, rounding
to the nearest month); or 
 (2) 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 (as defined below) for such redemption date. 
 The Adjusted Treasury Rate shall be
calculated on the third Business Day preceding the redemption date. 

  
 A-2-5 

 “Comparable Treasury Issue” means the United States Treasury security
selected by an Independent Investment Banker (as defined below) as having a maturity comparable to the remaining term of the Securities, calculated as if the maturity date of such Securities were the First Par Call Date (the “Remaining
Life”), that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the Remaining Life of the Securities . 

“Comparable Treasury Price” means, for any redemption date, (1) the average of four Reference Treasury Dealer Quotations
(as defined below) for such redemption date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (2) if the Independent Investment Banker obtains fewer than four such Reference Treasury Dealer Quotations, the average
of all such quotations. 
 “First Par Call Date” means May 15, 2029. 

“Independent Investment Banker” means one of the Reference Treasury Dealers appointed by the Company. 

“Reference Treasury Dealer” means any of the primary U.S. Government securities dealers in New York City. 

“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. 
 7. No Mandatory Redemption.
The Company shall not be required to make mandatory redemption payments with respect to the Securities. 
 8. Repurchase
at Option of Holder. Upon the occurrence of a Change of Control Triggering Event, and subject to certain conditions set forth in the Indenture, the Company shall be required to offer to purchase all of the outstanding Securities at a purchase
price equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, thereon to the date of repurchase. 

9. Notice of Redemption. Notice of redemption shall be mailed at least 15 days but not more than 60 days before the redemption
date to each Holder whose Securities are to be redeemed at its registered address, except that redemption notices may be mailed more than 60 days prior to a redemption date if the notice is issued in connection with Article 10 or Article 11 of the
Base Indenture. Securities in denominations larger than $2,000 may be redeemed in part but only in whole multiples of $1,000, unless all of the Securities held by a Holder are to be redeemed. Unless the Company defaults in payment of the redemption
price, on and after the redemption date interest shall cease to accrue on Securities or portions thereof called for redemption. 

10. Denominations, Transfer, Exchange. The Securities are in registered form, without coupons, in denominations of $2,000
principal amount and integral multiples of $1,000 principal amount. The transfer of Securities may be registered and Securities may be exchanged as provided in the Indenture. The Registrar may require a Holder, among other things, to furnish
appropriate endorsements and transfer documents. No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or similar governmental charge that may be
imposed in connection with certain transfers or exchanges. The Company shall not be required to register the transfer of or exchange any Security selected for redemption, except for the unredeemed portion of any Security being redeemed in part.
Also, the Company need not exchange or register the transfer of any Securities for a period of 15 days next preceding the first mailing of notice of redemption of Securities to be redeemed. 

11. Persons Deemed Owners. The registered Holder of a Security shall be treated as the owner of such Security for all
purposes. 

  
 A-2-6 

 12. Merger or Consolidation. The Company shall not consolidate with or
merge with or into, or sell, transfer, lease, convey or otherwise dispose of all or substantially all of its property or assets to, another Person (including pursuant to a statutory arrangement), whether in a single transaction or series of related
transactions, unless it complies with Article 8 of the Base Indenture. 
 13. Amendments, Supplements and
Waivers. The Indenture or the Securities may be amended or supplemented as provided in the Indenture. 

14. Defaults and Remedies. The Events of Default relating to the Securities are defined in Section 5.01 of the Base
Indenture. If any Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the then outstanding Securities may declare the principal, premium, if any, interest and any other monetary obligations on
all the then outstanding Securities to be due and payable immediately. Notwithstanding the foregoing, in the case of an Event of Default arising from certain events of bankruptcy or insolvency, all outstanding Securities shall become due and payable
immediately without further action or notice. 
 Holders may not enforce the Indenture or the Securities except as provided in the
Indenture. Subject to certain limitations, Holders of a majority in aggregate principal amount of the then outstanding Securities may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of the Securities
notice of any continuing Default (except a Default relating to the payment of principal, premium, if any, or interest) if it determines that withholding notice is in their interest. The Holders of a majority in aggregate principal amount of the
Securities then outstanding by notice to the Trustee may on behalf of the Holders of all of the Securities waive any existing Default and its consequences under the Indenture except a continuing Default in payment of the principal of, premium, if
any, or interest, if any, on, any of the Securities held by a non-consenting Holder. The Company is required to deliver to the Trustee annually a statement regarding compliance with the Indenture, and the Company is required upon becoming aware of
any Default or Event of Default, to deliver to the Trustee a statement specifying such Default or Event of Default. 

15. Trustee Dealings with the Company. The Trustee, in its individual or any other capacity, may make loans to, accept
deposits from, and perform services for the Company or its affiliates, and may otherwise deal with the Company or its affiliates, as if it were not the Trustee. 

16. No Recourse Against Others. A director, officer, employee, incorporator or stockholder, of the Company, as such, shall
not have any liability for any obligations of the Company under the Securities or the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting a Security waives and releases
all such liability. The waiver and release are part of the consideration for the issuance of the Securities. 

17. Authentication. This Security shall not be valid until authenticated by the manual signature of the Trustee or an
authenticating agent in accordance with the Indenture. 
 18. Abbreviations. Customary abbreviations may be used
in the name of a Holder 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). 
 19. CUSIP and ISIN Numbers. Pursuant to a recommendation promulgated by the Committee on Uniform Security
Identification Procedures, the Company has caused CUSIP and ISIN numbers to be printed on the Securities and the Trustee may use CUSIP and ISIN numbers in notices of redemption as a convenience to Holders. No representation is made as to the
accuracy of such numbers either as printed on the Securities or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon. 

THE COMPANY SHALL FURNISH TO ANY HOLDER UPON WRITTEN REQUEST AND WITHOUT CHARGE A COPY OF THE BASE INDENTURE OR THE SUPPLEMENTAL INDENTURE.
