ARTICLE 2 
 THE NOTES

 Section 2.01 Issuance; Form and Dating. (a) The Notes and the Trustee’s certificate of authentication shall
be substantially in the form of Exhibit A, which is hereby incorporated in and expressly made part of the Indenture. The Notes may have notations, legends or endorsements required by law, stock exchange rule, agreements to which the Company is
subject, if any, or usage (provided that any such notation, legend or endorsement is in a form acceptable to the Company). The Notes shall be issued in registered form without interest coupons and only in denominations of $2,000 and integral
multiples of $1,000 in excess thereof. 
 (b)        All of the Notes shall be issued initially in
the form of one or more Global Notes, which shall be deposited on behalf of the purchasers of the Notes represented thereby with the Trustee as Custodian for the depositary, The Depository Trust Company (“DTC”) (such depositary, or
any successor thereto, being hereinafter referred to as the “Depositary”), and registered in the name of its nominee, Cede & Co., duly executed by the Company and authenticated by the Trustee as hereinafter provided. The
aggregate principal amount of each Global Note may from time to time be increased or decreased by adjustments made on the records of the Custodian as hereinafter provided, subject in each case to compliance with the Applicable Procedures. 

(c)        Each Global Note shall represent such of the outstanding Notes as shall be specified
therein and each shall provide that it shall represent the aggregate amount of outstanding Notes from time to time endorsed thereon and that the aggregate amount of outstanding Notes represented thereby may from time to time be reduced or increased,
as appropriate, to reflect exchanges, purchases or conversions of such Notes. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the amount of outstanding Notes represented thereby shall be made by the Custodian in
accordance with the standing instructions and procedures existing between the Depositary and the Custodian. 

(d)        Members of, or participants in, the Depositary (“Agent Members”) shall
have no rights under the Indenture with respect to any Global Note held on their behalf by the Depositary or under 

  
 20 

 
any Global Note, and the Depositary (including, for this purpose, its nominee) may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner and
Holder of such Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall (1) prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy
or other authorization furnished by the Depositary or (2) impair, as between the Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights of a Holder of any Note. 

Section 2.02 Execution and Authentication. (a) An Officer shall sign the Notes for the Company by manual or facsimile
signature. Typographic and other minor defects in any facsimile signature shall not affect the validity or enforceability of any Note which has been authenticated and delivered by the Trustee. 

(b)        If an Officer whose signature is on a Note no longer holds that office at the time the
Trustee authenticates the Note, the Note shall be valid nevertheless. 
 (c)        A Note shall
not be valid until an authorized signatory of the Trustee manually signs the certificate of authentication on the Note. The signature shall be conclusive evidence that the Note has been authenticated under the Indenture. 

(d)        The Trustee will, upon receipt of a Company Order, authenticate Notes for original issue
that may be validly issued under the 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 2.08 hereof. 
 (e)        The
Trustee may appoint an authenticating agent acceptable to the Company to authenticate the Notes. Unless limited by the terms of such appointment, an authenticating agent may authenticate Notes whenever the Trustee may do so. Each reference in the
Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as any Registrar, Paying Agent or agent for service of notices and demands. 

Section 2.03 Registrar and Paying Agent. (a) The Company shall maintain an office or agency where the Notes may be presented
for registration of transfer or for exchange (the “Registrar”), and an office or agency where Notes may be presented for payment (“Paying Agent”). The Trustee shall initially act as the Registrar and Paying Agent.
The Registrar shall keep a register of the Notes and of their transfer and exchange. The Company may appoint one or more co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrar and the term
“Paying Agent” includes any additional paying agent. The Company may change any Paying Agent or Registrar without notice to any Holder. The Company shall notify the Trustee in writing of the name and address of any agent not a party to the
Indenture. If the Company fails to appoint or maintain another entity as the Registrar or Paying Agent, the Trustee shall act as such. The Company or any of its Subsidiaries may act as Paying Agent or Registrar. 

(b)        The Company initially appoints the Trustee to act as the Registrar and Paying Agent and to
act as Custodian with respect to the Notes. 
 Section 2.04 Maintenance of Office or Agency; Paying Agent to Hold Money in
Trust. (a) The Company shall maintain in the Borough of Manhattan, the City of New York, an office or agency (which may be an office of the Trustee or an affiliate of the Trustee, Registrar or co-registrar) where Notes may be surrendered
for registration of transfer or for exchange and where notices and demands to or upon the 

  
 21 

 
Company in respect of the Notes and the Indenture may be served. Such office shall initially be the office of the Trustee. 

(b)        The Company shall require each Paying Agent other than the Trustee to agree in writing
that the Paying Agent shall hold in trust for the benefit of the Holders or the Trustee all money held by the Paying Agent for the payment of principal of, or premium, if any, or interest on the Notes, and shall notify the Trustee of any Default by
the Company in making any such payment. While any such Default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Company at any time may require a Paying Agent to pay all money held by it to the
Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the Company or a Subsidiary) shall have no further liability for the money. If the Company or a Subsidiary acts as Paying Agent, it shall segregate and hold in a separate
trust fund for the benefit of the Holders all money held by it as Paying Agent. Upon any bankruptcy or reorganization proceedings relating to the Company, the Trustee shall serve as Paying Agent for the Notes. 

Section 2.05 Holder Lists. The Trustee shall preserve in as current a form as is reasonably practicable the most recent list
available to it of the names and addresses of Holders and shall otherwise comply with TIA § 312(a). If the Trustee is not the Registrar, the Company shall furnish to the Trustee at least 10 days before each interest payment date and at such
other times as the Trustee may request in writing a list, in such form and as of such date as the Trustee may reasonably require, of the names and addresses of Holders, and the Company shall otherwise comply with TIA § 312(a). 

Section 2.06 Transfer and Exchange. (a) The Notes shall be issued in registered form without interest coupons and only in
denominations of $2,000 and integral multiples of $1,000 in excess thereof. The Notes shall be transferable only upon the surrender of a Note for registration of transfer. When a Note is presented to the Registrar with a request to register a
transfer, the Registrar shall register the transfer as requested if the requirements of the Indenture are satisfied. When Notes are presented to the Registrar with a request to exchange them for an equal principal amount of Notes of other
denominations, the Registrar shall make the exchange as requested if the requirements of the Indenture are met. To permit registration of transfers and exchanges, the Company shall execute and the Trustee shall authenticate Notes at the
Registrar’s request. The Company or the Registrar may require payment by the Holder of a sum sufficient to pay all taxes, assessments or other governmental charges in connection with any transfer or exchange pursuant to this Section 2.06.

 (b)        Prior to the due presentation for registration of transfer of any Note, the Company,
the Trustee, the Paying Agent or the Registrar may deem and treat the Person in whose name a Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal of and (subject to the provisions of the Notes with
respect to record dates) interest on such Note and for all other purposes whatsoever, whether or not such Note is overdue, and none of the Company, the Trustee, the Paying Agent or the Registrar shall be affected by notice to the contrary. 

(c)        Neither the Company nor the Registrar shall be required (x) to issue, register the
transfer of, or exchange the Notes for the period beginning at the opening of business 15 days immediately preceding the sending of a notice of redemption of the Notes selected for redemption and ending at the close of business on the day of such
sending, or (y) to register the transfer of or exchange the Notes selected, called or being called for redemption as a whole or the portion being redeemed of any such Notes selected, called or being called for redemption in part. 

(d)        All Notes issued upon any transfer or exchange pursuant to the terms of the Indenture
shall evidence the same debt and shall be entitled to the same benefits under the Indenture as the Notes surrendered upon such transfer or exchange. 

  
 22 

 Section 2.07 Additional Transfer and Exchange Requirements. 

(a)        Transfer and Exchange of Global Notes. (1) Certificated Notes shall be issued
in exchange for interests in a Global Note only if (x) the Depositary notifies the Company that it is unwilling or unable to continue as depositary for the Global Note or if it at any time ceases to be a “clearing agency” registered
under the Exchange Act, (y) the Company in its discretion at any time determines not to have all the Notes represented by such Global Note or (z) upon an Event of Default or a Default has occurred and is continuing. In either such case,
the Company shall execute, and the Trustee shall, upon receipt of a Company Order and an Officers’ Certificate, authenticate and deliver Certificated Notes in an aggregate principal amount equal to the principal amount of such Global Notes in
exchange therefor. Certificated Notes issued in exchange for beneficial interests in Global Notes shall be issued only in registered form and only in denominations of $2,000 and integral multiples of $1,000 in excess thereof, and shall be registered
in such names as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. The Trustee shall deliver or cause to be delivered such Certificated Notes to the persons in whose names
such Notes are so registered. Such exchange shall be effected in accordance with the Applicable Procedures. (2) Notwithstanding any other provisions of the Indenture other than the provisions set forth in Section 2.07(a)(1), a Global Note
may not be transferred as a whole except by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or
a nominee of such successor Depositary. 
 (b)        Transfer and Exchange of Certificated
Notes. In the event that Certificated Notes are issued in exchange for beneficial interests in Global Notes in accordance with Section 2.07(a)(1) hereof, on or after such event when Certificated Notes are presented by a Holder to a
Registrar with a request: (x) to register the transfer of the Certificated Notes to a person who shall take delivery thereof in the form of Certificated Notes only; or (y) to exchange such Certificated Notes for an equal principal amount
of Certificated Notes of other authorized denominations, such Registrar shall register the transfer or make the exchange as requested if the requirements for such transaction under the Indenture are satisfied; provided, however, that
the Certificated Notes presented or surrendered for register of transfer or exchange shall be duly endorsed or accompanied by an assignment form and, if applicable, a transfer certificate each in the form included in Exhibit A, and in a form
satisfactory to the Registrar duly executed by the Holder thereof or its attorney duly authorized in writing. 

(c)        Transfers of Certificated Notes for Beneficial Interest in Global Notes. In the
event that Certificated Notes are issued in exchange for beneficial interests in Global Notes and, thereafter, the events or conditions specified in Section 2.07(a)(1) hereof, which required such exchange shall cease to exist, the Company shall
send notice to the Trustee and to the Holders stating that Holders may exchange Certificated Notes for interests in Global Notes by complying with the procedures set forth in the Indenture and briefly describing such procedures and the events or
circumstances requiring that such notice be given. Thereafter, if Certificated Notes are presented by a Holder to a Registrar with a request: (x) to register the transfer of such Certificated Notes to a person who shall take delivery thereof in
the form of a beneficial interest in a Global Note; or (y) to exchange such Certificated Notes for an equal principal amount of beneficial interests in a Global Note, which beneficial interests shall be owned by the Holder transferring such
Certificated Notes, the Registrar shall register the transfer or make the exchange as requested by canceling such Certificated Note and causing, or directing the Custodian to cause, the aggregate principal amount of the applicable Global Note to be
increased accordingly and, if no such Global Note is then outstanding, the Company shall issue and the Trustee shall authenticate and deliver a new Global Note; provided, however, that the Certificated Notes presented or surrendered
for registration of transfer or exchange shall be duly endorsed and accompanied by an assignment form and, if applicable, a transfer certificate each in the form included in Exhibit A, and in a form satisfactory to the Registrar duly executed by the
Holder thereof or its attorney duly authorized in writing. 

  
 23 

 (d)        Transfers to the Company. Nothing in
the Indenture or in the Notes shall prohibit the sale or other transfer of any Notes (including beneficial interests in Global Notes) to the Company or any of its Subsidiaries. 

(e)        No Obligation of the Trustee.  

(i)        The Trustee shall have no responsibility or obligation to any beneficial
owner of a Global Note, an Agent Member or other Person with respect to the accuracy of the books or records, or the acts or omissions, of the Depositary or its nominee or of any Agent Member thereof, with respect to any ownership interest in the
Notes or with respect to the delivery to any Agent Member, beneficial owner or other Person (other than the Depositary) of any notice or the payment of any amount, under or with respect to such Notes. All notices and communications to be given to
the Holders and all payments to be made to Holders under the Notes shall be given or made only to or upon the order of the registered Holders (which shall be the Depositary or its nominee in the case of a Global Note). The rights of beneficial
owners in any Global Note shall be exercised only through the Depositary subject to the Applicable Procedures of the Depositary. The Trustee may rely and shall be fully protected in relying upon information furnished by the Depositary with respect
to its Agent Members and any beneficial owners. 
 (ii)        The Trustee shall
have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under the Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers
between or among Agent Members or beneficial owners in any Global Note) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by, the terms
of the Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof. 

Section 2.08 Mutilated, Destroyed, Lost and Stolen Notes. (a) If any mutilated Note is surrendered to the Trustee, the
Company shall execute and the Trustee, upon receipt of a Company Order, shall authenticate and deliver in exchange therefor a new Note of like tenor and principal amount and bearing a number not contemporaneously outstanding. 

(b)        If there shall be delivered to the Company and the Trustee (i) evidence to their
satisfaction of the destruction, loss or theft of any Note and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, 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 the Trustee, upon receipt of a Company Order, shall authenticate and make available for delivery, in lieu of any such destroyed, lost or stolen Note, a
new Note of like tenor and principal amount and bearing a number not contemporaneously outstanding. 

(c)        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. 

(d)        Upon the issuance of any new Note under this Section 2.08, 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. 

  
 24 

 (e)        Every new Note issued pursuant to this
Section 2.08 in lieu of any destroyed, lost or stolen Note shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Note shall be at any time enforceable by anyone, and shall be
entitled to all the benefits of the Indenture equally and proportionately with any and all other Notes duly issued hereunder. 

(f)        The provisions of this Section 2.08 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 2.09 Outstanding Notes. (a) The Notes outstanding at any time are all the Notes authenticated by the Trustee except
for those canceled by it, those delivered to it for cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described in this Section 2.09 as not outstanding.

 (b)        If a Note is replaced pursuant to Section 2.08 hereof, it ceases to be
outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a bona fide purchaser. 

(c)        If the principal amount of any Note is considered paid under Section 4.01 hereof, it
ceases to be outstanding and interest on it ceases to accrue. 
 (d)        If the Paying Agent
(other than the Company, a Subsidiary or an Affiliate of any thereof) holds, on a redemption date or maturity date, money sufficient to pay the Notes payable on that date, then on and after that date such Notes shall be deemed to be no longer
outstanding and shall cease to accrue interest. 
 (e)        A Note does not cease to be
outstanding because the Company or an Affiliate holds the Note. 
 Section 2.10 Treasury Notes. In determining whether the
Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Company, or by any Affiliate of the Company, shall be considered as though not outstanding, except that for the purposes of
determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes that the Trustee actually knows are so owned shall be so disregarded. 

Section 2.11 Temporary Notes. In the event Certificated Notes are to be issued under the terms of the Indenture, until
certificates representing the Notes are ready for delivery, the Company may prepare and the Trustee, upon receipt of a Company Order, shall authenticate temporary Notes. Temporary Notes shall be substantially in the form of Certificated Notes but
may have variations that the Company considers appropriate for temporary Notes and as shall be reasonably acceptable to the Trustee. Without unreasonable delay, the Company shall prepare and the Trustee, upon receipt of a Company Order, shall
authenticate Certificated Notes in exchange for temporary Notes. Until so exchanged, temporary Notes shall have the same rights under the Indenture as the Certificated Notes. 

Section 2.12 Cancellation. The Company at any time may deliver Notes to the Trustee for cancellation. The Registrar and the Paying
Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee shall cancel all Notes surrendered for transfer, exchange, payment, replacement or cancellation and shall destroy such
canceled Notes (subject to the record retention requirement of the Exchange Act) and deliver a certificate of such destruction to the Company, unless the Company otherwise directs. The Company may not issue new Notes to replace Notes that it has
paid or delivered to the Trustee for cancellation. 

  
 25 

 Section 2.13 Defaulted Interest. If the Company defaults in a payment of interest on
the Notes, it shall pay the defaulted interest, plus, to the extent permitted by law, any interest payable on the defaulted interest, to the persons who are Holders on a subsequent special record date. The Company shall fix the special record date
and payment date. At least 30 days before the special record date, the Company shall send to the Trustee and to each Holder of the Notes a notice that states the special record date, the payment date and the amount of defaulted interest and the
amount of interest payable on such defaulted interest, if any, to be paid. The Company may pay defaulted interest in any other lawful manner. 

Section 2.14 CUSIP Numbers. The Company in issuing the Notes may use “CUSIP” numbers (if then generally in use), and, if
so, the Trustee shall use “CUSIP” numbers in notices of redemption as a convenience to Holders; provided, however, 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 and that reliance may be placed only on the other elements of identification printed on the Notes, and any such redemption shall not be affected by any defect in or omission of such
numbers.

Notes issued under the Indenture shall be treated as a single class for all purposes of the Indenture including waivers, amendments, redemptions and offers to purchase. 

(b)        With respect to any Additional Notes, the Company shall set forth in a Board Resolution
and an Officers’ Certificate, a copy of each which shall be delivered to the Trustee, the following information: 

(i)         the aggregate principal amount of such Additional Notes to be
authenticated and delivered pursuant to the Indenture and the provision of Section 4.09 that the Company is relying on to issue such Additional Notes; and 

(ii)         the issue price, the issue date and the CUSIP number of such Additional
Notes; provided, however, that no Additional Notes may be issued at a price that would cause such Additional Notes to not be fungible for U.S. federal income tax purposes with any other Notes issued under the Indenture.

Section 3.02 Selection of Notes to Be Redeemed.

not more than 60 days before a redemption date, the Company shall send a notice of redemption to each Holder whose Notes are to be redeemed at its registered address. The notice shall identify the Notes to be redeemed and shall state: 

(i)        the redemption date; 

(ii)        the redemption price, or if not then ascertainable, either (i) the
manner of calculation thereof or (ii) the redemption price calculated using the Treasury Rate as of the Business Day immediately prior to the date on which the notice of redemption is delivered; 

(iii)        if any Note is being redeemed in part, the portion of the principal
amount of such Note to be redeemed and that, after the redemption date upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion shall be issued upon cancellation of the original Note;

no representation is made as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the Notes. 
 In addition, if
such redemption is subject to the satisfaction of one or more conditions precedent, such notice shall describe each such condition and, if applicable, shall state that, in the Company’s 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 stated in such notice, or by
the redemption date as so delayed. 

  
 27 

 (b)        At the Company’s request, the Trustee
shall give the notice of redemption in the Company’s name and at its expense; provided, however, that the Company shall have delivered to the Trustee, at least five Business Days before such notice is to be given (or such shorter period
of time as the Trustee may agree), an Officers’ Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in Section 3.03(a) hereof. 

(c)        If the redemption price is not ascertainable on the date on which the notice of redemption
is delivered, the Company shall send to the Trustee, at least one Business Day prior to the redemption date, notice of the redemption price. 

Section 3.04 Effect of Notice of Redemption. Once notice of redemption is sent in accordance with Section 3.03 hereof, the
Notes called for redemption, subject to any condition included in the applicable notice of redemption, become irrevocably due and payable on the redemption date at the redemption price. A notice of redemption may be conditional. 

Section 3.05 Deposit of Redemption Price. (a) One Business Day prior to the redemption date, the Company shall deposit with
the Trustee or with the Paying Agent money sufficient to pay the redemption price of and accrued interest on all the Notes to be redeemed on that date. The Trustee or the Paying Agent shall 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 price of, and accrued interest on, all Notes to be redeemed. 

(b)        If the Company complies with the provisions of Section 3.05(a), on and after the
redemption date, interest shall cease to accrue on the Notes or the portions of the Notes called for redemption. If a Note is redeemed on or after an interest record date but on or prior to the related interest payment date, then any accrued and
unpaid interest shall be paid to the Person in whose name such Note was registered at the close of business on such record date. If any Note called for redemption shall not be so paid upon surrender for redemption because of the failure of the
Company to comply with Section 3.05(a), interest shall be paid on the unpaid principal, from the redemption date until such principal is paid, and, to the extent lawful, on any interest not paid on such unpaid principal, in each case at the
rate provided in the Notes. 
 Section 3.06 Notes Redeemed in Part. Upon surrender of a Note that is redeemed in part, the

Section 3.07 Optional Redemption.

aggregate principal amount of the Notes to be redeemed or (2) the sum of the present values of the Remaining Scheduled Payments. In determining the present values of the Remaining Scheduled Payments, the Company will discount such payments to
the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) using a discount rate equal to the Treasury Rate plus 50 basis points. 

(b)        Notwithstanding the provisions of Section 3.07(a) hereof, on or before April 15,
2017, the Company may on any one or more occasions redeem up to 35% of the aggregate principal amount of Notes issued, including any Additional Notes issued pursuant to Section 2.16 hereof, at a

  
 28 

 
redemption price of 104.875% of the principal amount of the Notes to be redeemed on the redemption date with the net cash proceeds of one or more Equity Offerings; provided that: 

(i)        at least 65% of the aggregate principal amount of Notes issued, including
any Additional Notes issued pursuant to Section 2.16 hereof, remains outstanding immediately after the occurrence of such redemption, excluding Notes held by the Company or any of its Subsidiaries; and 

(ii)        the redemption occurs within 120 days of the date of the closing of the
Equity Offering.

the Company required to be purchased pursuant to Section 4.10(e) hereof (on a pro rata basis if Notes and other senior Indebtedness of the Company tendered are in excess of the Excess Proceeds) (which maximum amount shall be the “Offer
Amount”) or, if less than the Offer Amount has been tendered, all Notes and other senior Indebtedness tendered in response to the Asset Sale Offer. Payment for any Notes so purchased shall be made in the same manner as interest payments are
made. 
 (c)        If the Purchase Date is on or after an interest record date and on or before
the related interest payment date, any accrued and unpaid interest, if any, shall be paid to the Person in whose name a Note is registered at the close of business on such record date, and no additional interest shall be payable to Holders who
tender Notes pursuant to the Asset Sale Offer. 
 (d)        Upon the commencement of an Asset Sale
Offer, the Company shall send a notice to the Trustee and each of the Holders, with a copy to the Trustee. The notice shall contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Asset Sale Offer. The
Asset Sale Offer shall be made to all Holders. The notice, which shall govern the terms of the Asset Sale Offer, shall state:

(ii)        that any Note not tendered or accepted for payment shall continue to
accrue interest;

have a Note purchased pursuant to an Asset Sale Offer may elect to have Notes purchased in a minimum denomination of $2,000 and integral multiples of $1,000 only; 

(v)        that Holders electing to have a Note purchased pursuant to any Asset Sale
Offer shall be required to surrender the Note, with the form entitled “Option of Holder to Elect Purchase” on the reverse of the Note completed, or transfer by book-entry transfer, to the Company, a depositary, if appointed by the Company,
or a Paying Agent, at the address specified in the notice at least three days before the Purchase Date; 

(vi)        that Holders shall be entitled to withdraw their election if the Company,
the Depositary or the Paying Agent, as the case may be, receives, not later than the expiration of the Offer Period, a telegram, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Note the Holder
delivered for purchase and a statement that such Holder is withdrawing his election to have such Note purchased; 

(vii)        that, if the aggregate principal amount (or accreted value, as
applicable) of Notes and other senior Indebtedness of the Company surrendered by Holders exceeds the Offer Amount, the Company shall select the Notes to be purchased on a pro rata basis (with such adjustments as may be deemed appropriate by the
Company so that only Notes in minimum denominations of $2,000 and integral multiples of $1,000, shall be purchased); and 

(viii)        that Holders whose Notes were purchased only in part shall be issued
new Notes equal in principal amount to the unpurchased portion of the Notes surrendered (or transferred by book-entry transfer). 

(e)        On or before the Purchase Date, the Company shall, to the extent lawful, accept for
payment, on a pro rata basis to the extent necessary, the Offer Amount of Notes and other senior Indebtedness, or portions thereof, tendered pursuant to the Asset Sale Offer, or if less than the Offer Amount has been tendered, all Notes and other
senior Indebtedness tendered, and shall deliver to the Trustee an Officers’ Certificate stating that such Notes or portions thereof were accepted for payment by the Company in accordance with the terms of this Section 3.08. The Company,
the Depositary or the Paying Agent, as the case may be, shall promptly (but in any case not later than five days after the Purchase Date) mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes tendered by such
Holder and accepted by the Company for purchase, and if the Note surrendered was a Certificated Note, the Company shall promptly issue a new Certificated Note, without service charge, and the Trustee, upon receipt of a Company Order, shall
authenticate and mail such new Certificated Note to such Holder, in a principal amount equal to any unpurchased portion of the Certificated Note surrendered. Any Note not so accepted shall be promptly mailed or delivered by the Company to the Holder
thereof. The Company shall publicly announce the results of the Asset Sale Offer on the Purchase Date. 

(f)        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 those laws and regulations are applicable in connection with each repurchase of Notes pursuant to this Section 3.08. To the extent that the provisions of any securities laws or
regulations conflict with this Section 3.08 hereof, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 3.08 or Section 4.10 hereof by
virtue of such compliance.

unless, at the time of and after giving effect to such Restricted Payment: 

(i)        no Default has occurred and is continuing or would occur as a consequence

beginning of the most recently ended four full fiscal quarter period of the Company for which internal financial statements are available. 

(b)        The preceding provisions shall not prohibit: 

(i)        the payment of any dividend within 60 days after the date of declaration
of that dividend if at said date of declaration such payment would have complied with the provisions of the Indenture; 

(ii)        the making of any Restricted Payment in exchange for, or out of the net

or retired Equity Interests pursuant to this Section 4.07(b)(v) shall not exceed $15.0 million in any Fiscal Year; or 

(vi)        other Restricted Payments in an aggregate amount not to exceed $50.0
million at any time outstanding. 
 (c)        The Board of Directors may designate any Restricted
Subsidiary to be an Unrestricted Subsidiary if such designation would not cause a Default. For purposes of making such determination, all outstanding Investments by the Company and its Restricted Subsidiaries (except to the extent repaid in cash) in
the Subsidiary so designated shall be deemed to be Restricted Payments at the time of the designation. All of those outstanding Investments shall be deemed to constitute Investments in an amount equal to the fair market value of the Investments at
the time of such designation. Such designation shall only be permitted if the Restricted Payment would be permitted at the time and if the Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. The Board of Directors may
designate any Unrestricted Subsidiary to be a Restricted Subsidiary if the designation would not cause a Default. 

(d)        The amount of all Restricted Payments (other than cash) shall be the fair market value on
the date of the Restricted Payment of the assets or securities proposed to be transferred or issued by the Company or the applicable Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment. The fair market value of any
property, assets or Investments required by this Section 4.07 to be valued will be valued by the Company and evidenced by an Officers’ Certificate delivered to the Trustee. 

Section 4.08 Dividend and Other Payment Restrictions Affecting Subsidiaries. (a) The Company shall not, and shall not permit
any of its Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or suffer to exist or become effective any consensual encumbrance or restriction on the ability of any Restricted Subsidiary to: 

(i)        pay dividends or make any other distributions to the Company on its
Capital Stock or with respect to any other interest or participation in, or measured by, its profits;

restrictions existing under or by reason of: 
 (i)        Existing Indebtedness or
other agreements as in effect on the date hereof, and any amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings thereof; provided that either (1) such amendments,
modifications, restatements, renewals, increases, supplements, refundings, 

  
 35 

 
replacements or refinancings are not materially more restrictive, taken as a whole, with respect to such dividend and other payment restrictions than those contained in the applicable series of
Existing Indebtedness or agreement as in effect on the date hereof or (2) the Company determines that any such encumbrance or restriction shall not materially affect the Company’s ability to pay interest or principal, when due, on the
Notes (which determination shall be made in the good faith judgment of the Company, which determination shall be conclusively binding); 

(ii)        Indebtedness of any Restricted Subsidiary under any Credit Facility that
is permitted to be incurred or outstanding pursuant to Section 4.09 hereof; provided that such Credit Facility and Indebtedness contain only such encumbrances and restrictions on such Restricted Subsidiary’s ability to engage in the
activities set forth in clauses (i) through (iv) of Section 4.08(a) hereof as are, at the time such Credit Facility is entered into or amended, modified, restated, renewed, increased, supplemented, refunded, replaced or refinanced,
ordinary and customary for a Credit Facility of that type as determined in the good faith judgment of the Company, which determination shall be conclusively binding; 

(iii)        encumbrances and restrictions applicable to any Person, as the same are
in effect as of the date on which such Person becomes a Restricted Subsidiary, and as the same may be amended, modified, restated, renewed, increased, supplemented, refunded, replaced or refinanced; provided that such amendments,
modifications, restatements, renewals, increases, supplements, refundings, replacement or refinancings are no more restrictive, taken as a whole, with respect to the dividend and other payment restrictions than those contained in the applicable
series of Indebtedness of such Person as in effect on the date on which such Person becomes a Restricted Subsidiary; 

(iv)        any Indebtedness incurred in compliance with Section 4.09 hereof or
any agreement pursuant to which such Indebtedness is issued if the encumbrance or restriction applies only in the event of a payment default or default with respect to a financial covenant contained in the Indebtedness or agreement and the
encumbrance or restriction is not materially more disadvantageous to the Holders than is customary in comparable financings (as determined in the good faith judgment of the Company, which determination shall be conclusively binding) and the Company
determines that any such encumbrance or restriction shall not materially affect the Company’s ability to pay interest or principal on the Notes; 

(v)        the Indenture; 

(vi)        applicable law; 

(vii)        any instrument governing Indebtedness or Capital Stock of a Person
acquired by the Company or any of its Restricted Subsidiaries as in effect at the time that Person is acquired by the Company (except to the extent the Indebtedness was incurred in connection with or in contemplation of the acquisition), which
encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired, provided that, in the case of Indebtedness, the Indebtedness was
permitted by the terms of the Indenture to be incurred; 

  
 36 

 (viii)        customary non-assignment
and other restrictive provisions in leases, licenses, easements or similar arrangements entered into in the ordinary course of business;

of business of the nature described in Section 4.09(b)(iv) hereof on the property so acquired or under Excluded Capital Lease Obligations with respect to the property subject thereto; 

(x)        any agreement for the sale of a Restricted Subsidiary that restricts that
Restricted Subsidiary pending its sale; 
 (xi)        Permitted Refinancing
Indebtedness, provided that either (1) the restrictions contained in the agreements governing the Permitted Refinancing Indebtedness are not materially more restrictive, taken as a whole, than those contained in the agreements governing
the Indebtedness being refinanced or (2) the Company determines that any such encumbrance or restriction shall not materially affect the Company’s ability to pay interest or principal, when due, on the Notes (which determination shall be
made in the good faith judgment of the Company, which determination shall be conclusively binding); 

(xii)        Liens permitted to be incurred pursuant to Section 4.12 hereof that
limit the right of the debtor to transfer the assets subject to such Liens;

conclusively binding); and 
 (xvi)        Indebtedness permitted to be incurred
pursuant to Section 4.09(b)(xiv) hereof; provided that the Company determines that any such encumbrance or restriction shall not materially affect the Company’s ability to pay interest or principal, when due, on the Notes (which

Section 4.09 Incurrence of Indebtedness and Issuance of Preferred Stock. (a) The Company shall not, and shall not permit any
of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “incur”) any Indebtedness
(including Acquired Debt) and the Company shall not issue any Disqualified Stock and shall not permit any of its Restricted Subsidiaries to issue any shares of preferred stock; provided that the Company may incur Indebtedness (including
Acquired Debt) or issue 

  
 37 

 
shares of Disqualified Stock and the Company’s Restricted Subsidiaries may incur Indebtedness (including Acquired Debt) or issue preferred stock if, in each case, the Company’s Debt to
Adjusted Consolidated Cash Flow Ratio at the time of incurrence of the Indebtedness or the issuance of the Disqualified Stock or preferred stock, after giving pro forma effect to such incurrence or issuance as of such date and to the use of proceeds
from such incurrence or issuance as if the same had occurred at the beginning of the most recently ended four full fiscal quarter period of the Company for which internal financial statements are available, would have been no greater than 7.0 to 1.

 (b)        Section 4.09(a) shall not prohibit the incurrence of any of the following items
of Indebtedness or the issuance of any of the following items of Disqualified Stock or preferred stock (collectively, “Permitted Debt”): 

(i)        the incurrence by the Company or any of its Restricted Subsidiaries of
Indebtedness under the Senior Credit Facility in an aggregate principal amount (with letters of credit being deemed to have a principal amount equal to the maximum potential liability of the Company and its Restricted Subsidiaries thereunder) at any
one time outstanding not to exceed $1.5 billion; 
 (ii)        the incurrence by
the Company or its Restricted Subsidiaries of the Existing Indebtedness; 

(iii)        the incurrence by the Company of the Indebtedness represented by the
Notes to be issued on the date hereof; 
 (iv)        the incurrence by the Company
or any of its Restricted Subsidiaries of Indebtedness since the date hereof represented by Capital Lease Obligations, mortgage financings or purchase money obligations, in each case incurred for the purpose of financing all or any part of the
purchase price or cost of construction or improvement of property, plant or equipment used in the business of the Company or such Restricted Subsidiary (including any Indebtedness incurred for such purpose within 270 days of such purchase,
construction or improvement), in an aggregate principal amount, including all Permitted Refinancing Indebtedness incurred to refund, refinance or replace any other Indebtedness incurred pursuant to this Section 4.09(b)(iv), not to exceed $75.0
million at any one time outstanding; 
 (v)        the incurrence by the Company or
any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to extend, refinance, renew, replace, defease or refund Indebtedness of the Company or any of its Restricted Subsidiaries
or Disqualified Stock of the Company (other than intercompany Indebtedness) that was permitted by the Indenture to be incurred under Section 4.09(a) or clauses (ii), (iii), this clause (v) or clause (ix) of Section 4.09(b); 

(vi)        the incurrence by the Company or any of its Restricted Subsidiaries of
intercompany Indebtedness between or among the Company and any of its Restricted Subsidiaries; provided, however, that if the Company is the obligor on such Indebtedness, such Indebtedness is expressly subordinated to the prior payment
in full in cash of all obligations with respect to the Notes and that: 

(A)        any subsequent issuance or transfer of Equity Interests that results in
any such Indebtedness being held by a Person other than the Company or a Restricted Subsidiary; and 

  
 38 

 (B)        any sale or other transfer of
any such Indebtedness to a Person that is not either the Company or a Restricted Subsidiary; 
 shall be deemed, in each case, to
constitute an incurrence of the Indebtedness by the Company or the Restricted Subsidiary, as the case may be; 

(vii)        the incurrence by the Company or any of its Restricted Subsidiaries of
Hedging Obligations that are incurred for the purpose of fixing or hedging (1) interest rate risk or (2) currency exchange risk, and, in either case, not for speculative purposes; 

(viii)        the guarantee by the Company or any of its Restricted Subsidiaries of
Indebtedness of the Company or a Restricted Subsidiary of the Company that was permitted to be incurred by another provision of the Indenture; 

(ix)        the incurrence by the Company or any of its Restricted Subsidiaries of
Acquired Debt in connection with the acquisition of assets or a new Subsidiary and the incurrence by the Company’s Restricted Subsidiaries of Indebtedness as a result of the designation of an Unrestricted Subsidiary as a Restricted Subsidiary;
provided that, in the case of any such incurrence of Acquired Debt, such Acquired Debt was incurred by the prior owner of such assets or such Restricted Subsidiary prior to such acquisition by the Company or one of its Restricted Subsidiaries
and was not incurred in connection with, or in contemplation of, the acquisition by the Company or one of its Restricted Subsidiaries; and provided further that, in the case of any incurrence pursuant to this Section 4.09(b)(ix),
as a result of such acquisition by the Company or one of its Restricted Subsidiaries, the Company’s Debt to Adjusted Consolidated Cash Flow Ratio at the time of incurrence of such Acquired Debt, after giving pro forma effect to such transaction
as if the same had occurred at the beginning of the most recently ended four full fiscal quarter period of the Company for which internal financial statements are available, would have been either (1) no greater than 7.0 to 1 or (2) less
than the Company’s Debt to Adjusted Consolidated Cash Flow Ratio for the same period without giving pro forma effect to such transaction; 

(x)        the incurrence by the Company or any of its Restricted Subsidiaries of any
Indebtedness in respect of (1) performance bonds, bankers’ acceptances, letters of credit, surety or appeal bonds or similar instruments provided by the Company or any Restricted Subsidiary in the ordinary course of business, (2) the
financing of insurance premiums in the ordinary course of business or (3) netting, overdraft protection and other arrangements arising under standard business terms of any bank at which the Company or any Restricted Subsidiary maintains an
overdraft, cash pooling or other similar facility or arrangement; 

(xi)        the incurrence by the Company or any of its Restricted Subsidiaries of
any Indebtedness arising from the honoring by a bank or other financial institution of a check, draft or similar instrument drawn against insufficient funds in the ordinary course of business, provided that such Indebtedness is extinguished
within five Business Days of its incurrence; 
 (xii)        the incurrence by the
Company or any of its Restricted Subsidiaries of any Indebtedness consisting of indemnification, adjustment of purchase price, earn-out or similar obligations of the Company or any Restricted Subsidiary, in each case incurred in

  
 39 

 
connection with the acquisition or disposition of any assets, business or Person by the Company or any Restricted Subsidiary; 

(xiii)         the incurrence by the Company or any of its Restricted Subsidiaries of
any Guarantees in the ordinary course of business of the obligations of suppliers, customers, franchisers and licensees; 

(xiv)        the incurrence by Foreign Subsidiaries of additional Indebtedness, the
proceeds of which are used for ordinary course business purposes, in an aggregate principal amount, at any time outstanding, not to exceed $25.0 million; and 

(xv)        the incurrence by the Company or any of its Restricted Subsidiaries since
the date hereof of additional Indebtedness and/or the issuance by the Company of Disqualified Stock in an aggregate principal amount, accreted value or liquidation preference, as applicable, at any time outstanding, not to exceed $100.0 million.

 (c)        The Company shall not incur any Indebtedness that is contractually subordinated in
right of payment to any other Indebtedness of the Company unless such Indebtedness is also contractually subordinated in right of payment to the Notes on substantially identical terms; provided, however, that no Indebtedness the
Company shall be deemed to be contractually subordinated in right of payment to any other indebtedness of the Company solely by virtue of being unsecured or secured on a junior priority basis. 

(d)        For purposes of determining compliance with this Section 4.09, in the event that an
item of Indebtedness meets the criteria of more than one of the categories of Permitted Debt described in clauses (i) through (xv) of Section 4.09(b) above or is entitled to be incurred pursuant to Section 4.09(a), the Company
shall, in its sole discretion, classify (or later reclassify in whole or in part) such item of Indebtedness in any manner (and in any order) that complies with this Section 4.09, including in circumstances where such Indebtedness is otherwise
incurred substantially concurrently. Accrual of interest, accretion or amortization of original issue discount and the payment of interest in the form of additional Indebtedness shall not be deemed to be an incurrence of Indebtedness for purposes of
this Section 4.09. For the avoidance of doubt, any such accretion or payment is considered, for purposes of Section 4.09(b)(v) hereof, to be permitted and outstanding under the paragraph or clause pursuant to which the underlying
Indebtedness was incurred. Indebtedness under the revolving portion of the Senior Credit Facility, if any, outstanding on the date hereof shall be deemed to have been incurred on such date in reliance on the exception provided by
Section 4.09(b)(i) hereof, and all other Indebtedness under the Senior Credit Facility or the Tower Cash Flow Facilities outstanding on the date hereof shall be deemed to have been incurred on such date in reliance on the exception provided by
Section 4.09(b)(ii) hereof. 
 Section 4.10 Asset Sales. (a) The Company shall not, and shall not permit any of its
Restricted Subsidiaries to, consummate an Asset Sale unless: 
 (i)        the
Company (or the Restricted Subsidiary, as the case may be) receives consideration at the time of the Asset Sale at least equal to the fair market value of the assets or Equity Interests issued or sold or otherwise disposed of; 

(ii)        in the case of any Asset Sale in excess of $100.0 million, fair market
value is determined by the Board of Directors and evidenced by a Board Resolution set forth in an Officers’ Certificate delivered to the Trustee; and 

  
 40 

 (iii) except in the case of a Tower Asset Exchange, at least 75% of the
consideration received in such Asset Sale by the Company or such Restricted Subsidiary is in the form of cash or Cash Equivalents. 

(b)        For purposes of Section 4.10(a)(iii) above only, each of the following shall be
deemed to be cash: 
 (i)        any liabilities, as shown on the Company’s or
such Restricted Subsidiary’s most recent balance sheet, of the Company or any Restricted Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated to the Notes or any Guarantee of the Notes) that are
assumed by the transferee of any assets pursuant to a customary novation agreement that releases the Company or the Restricted Subsidiary from further liability; 

(ii)        any securities, notes or other obligations received by the Company or any
Restricted Subsidiary from the transferee that are converted by the Company or the Restricted Subsidiary into cash within 270 days of the applicable Asset Sale, to the extent of the cash received in that conversion; and 

(iii)        any Designated Noncash Consideration received by the Company or any of
its Restricted Subsidiaries in an Asset Sale having an aggregate fair market value, taken together with all other Designated Noncash Consideration received pursuant to this Section 4.10(b)(iii), not to exceed $150.0 million in the aggregate at
any time outstanding (with the fair market value of each item of Designated Noncash Consideration being measured at the time received and without giving effect to subsequent changes in value). 

(c)        Within 365 days after the receipt of any Net Proceeds from an Asset Sale, the Company or
the Restricted Subsidiary may apply those Net Proceeds to: 
 (i)        reduce
non-subordinated Indebtedness of the Company; 
 (ii)        reduce Indebtedness or
Excluded Capital Lease Obligations of any of the Company’s Restricted Subsidiaries (including by way of the Company or a Restricted Subsidiary acquiring outstanding Indebtedness of any Restricted Subsidiary to be held by the Company or a
Restricted Subsidiary to redemption or maturity of such Indebtedness); 

(iii)        acquire all or substantially all the assets of a Permitted Business;

 (iv)        acquire Voting Stock of a Permitted Business from a Person that is
not a Subsidiary of the Company; provided that, after giving effect to the acquisition, the Company or its Restricted Subsidiary owns a majority of the Voting Stock of that Permitted Business; or 

(v)        make a capital expenditure or acquire other long-term assets (including
long-term land use easements, ground leases and similar land rights) that are used or useful in a Permitted Business. 

(d)        Pending the final application of any Net Proceeds, the Company may temporarily reduce
revolving credit borrowings or otherwise apply or invest the Net Proceeds in any manner that is not prohibited by the Indenture. 

  
 41 

 (e)        Any Net Proceeds from Asset Sales that are
not applied or invested as provided in Section 4.10(c) (whether by election or the passage of time) shall be deemed to constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $25.0 million, the
Company shall be required to make an offer to all Holders, and all holders of other senior Indebtedness of the Company containing provisions similar to those set forth in the Indenture with respect to offers to purchase or redeem with the proceeds
of sales of assets, to purchase the maximum principal amount of Notes and such other senior Indebtedness of the Company that may be purchased out of the Excess Proceeds (an “Asset Sale Offer”). The offer price in any Asset Sale
Offer shall be payable in cash and shall be 100% of the principal amount of any Notes, plus accrued and unpaid interest, if any (except as provided in Section 3.08(c) hereof), to the date of purchase. In the case of any other senior
Indebtedness, the offer price shall be 100% of the principal amount (or accreted value, as applicable) of the Indebtedness plus accrued and unpaid interest thereon, if any, to the date of purchase. Each Asset Sale Offer shall be made in accordance
with the procedures set forth in the Indenture and the other senior Indebtedness of the Company. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company may use the remaining Excess Proceeds for any purpose not otherwise
prohibited by the Indenture. If the aggregate principal amount of Notes and the other senior Indebtedness of the Company tendered into the Asset Sale Offer exceeds the amount of Excess Proceeds, the Company shall select the Notes to be purchased on
a pro rata basis. Upon completion of the Asset Sale Offer, the amount of Excess Proceeds shall be reset at zero. 

(f)        The Company shall comply with the requirements of Section 14(e) of the Exchange Act
and any other securities laws or regulations to the extent those laws and regulations are applicable to any Asset Sale Offer. If the provisions of any of the applicable securities laws or securities regulations conflict with the provisions of this
Section 4.10, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 4.10 by virtue of the compliance. 

Section 4.11 Transactions with Affiliates. (a) The Company shall not, and shall not permit any of its Restricted Subsidiaries
to, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance
or guarantee with, or for the benefit of, any Affiliate (each of the foregoing, an “Affiliate Transaction”), unless: 

(i)        such Affiliate Transaction is on terms that are no less favorable to the
Company or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated Person; and 

(ii)        the Company delivers to the Trustee, with respect to any Affiliate
Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $10.0 million, a Board Resolution set forth in an Officers’ Certificate certifying that the Affiliate Transaction complies with
Section 4.11(a)(i) above and that the Affiliate Transaction has been approved by a majority of the disinterested members of the Board of Directors. 

(b)        Notwithstanding the foregoing, the following items shall not be deemed to be Affiliate
Transactions: 
 (i)        any employment arrangements with any executive officer
of the Company or a Restricted Subsidiary that is entered into by the Company or any of its Restricted Subsidiaries in the ordinary course of business and consistent with 

  
 42 

 
compensation arrangements of similarly situated executive officers at comparable companies engaged in Permitted Businesses; 

(ii)        transactions between or among the Company and/or its Restricted
Subsidiaries; 
 (iii)        payment of reasonable and customary directors’
fees; 
 (iv)        Restricted Payments that are permitted by Section 4.07
hereof (including Permitted Investments) and loans or advances to employees made in the ordinary course of business and consistent with past practices; 

(v)        the issuance or sale of Equity Interests (other than Disqualified Stock)
of the Company; and 
 (vi)        payments of customary fees by the Company or any
of its Restricted Subsidiaries to any independent investment bank or Affiliate of an independent investment bank made for any corporate advisory services or financial advisory, financing, underwriting or placement services or in respect of other
investment banking activities including, without limitation, in connection with acquisitions or divestitures, which are approved by a majority of the Board of Directors in good faith. 

Section 4.12 Liens. The Company shall not, directly or indirectly, create, incur, assume or suffer to exist any Lien securing
Indebtedness on any asset directly held by the Company now owned or hereafter acquired, or any income or profits therefrom or assign or convey any right to receive income therefrom, except Permitted Liens, without providing that the Notes shall be
secured equally and ratably with (or prior to) the obligations so secured for so long as such obligations are so secured. 

Section 4.13 Business Activities. The Company shall not, and shall not permit any Restricted Subsidiary to, engage in any business
other than Permitted Businesses, except to the extent as would not be material to the Company and its Restricted Subsidiaries taken as a whole. 

Section 4.14 Reserved. 

Section 4.15 Offer to Repurchase Upon Change of Control. (a) If a Change of Control occurs, each Holder shall have the right
to require the Company to repurchase all or any part of the principal amount of such Holder’s Notes equal to $2,000 or an integral multiple of $1,000 pursuant to the offer described below (the “Change of Control Offer”). The
offer price in any Change of Control Offer shall be payable in cash and shall be equal to 101% of the aggregate principal amount of any Notes repurchased plus accrued and unpaid interest on the Notes, if any (subject to the right of Holders of
record on the relevant record date to receive interest due on the relevant interest payment date), to the date of purchase (the “Change of Control Payment”). Within 30 days following any Change of Control, the Company shall send a
notice to each Holder describing the transaction or transactions that constitute the Change of Control and offering to repurchase Notes on the date specified in the notice (the “Change of Control Payment Date”). The Change of
Control Payment Date shall be no earlier than 30 days and no later than 60 days from the date the notice is sent, pursuant to the procedures required by the Indenture and described in such notice. 

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

  
 43 

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

(ii)        deposit with the Paying Agent an amount equal to the Change of Control
Payment in respect of all Notes or portions of Notes properly tendered; and 

(iii)        deliver or cause to be delivered to the Trustee the Notes so accepted
together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions of the Notes being purchased by the Company. 

(c)        The Paying Agent shall promptly send to each Holder of Notes properly tendered the Change
of Control Payment for such Notes, and the Trustee shall promptly authenticate and mail or send, or cause to be transferred by book entry, to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if
any; provided that the new Note shall be in a principal amount of $2,000 or an integral multiple of $1,000. 

(d)        The Change of Control provisions described in this Section 4.15 shall be applicable
whether or not any other provisions of the Indenture are applicable. The Company shall comply with the requirements of Section 14(e) of the Exchange Act and any other securities laws or regulations to the extent those laws and regulations are
applicable to any Change of Control Offer. If the provisions of any of the applicable securities laws or securities regulations conflict with the provisions of this Section 4.15, the Company shall comply with the applicable securities laws and
regulations and shall not be deemed to have breached its obligations under the covenant described above by virtue of the compliance. 

(e)        The Company shall not be required to make a Change of Control Offer upon a Change of
Control 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 the Indenture applicable to a Change of Control Offer made by the Company and purchases all Notes
properly tendered and not withdrawn under such Change of Control Offer. In addition, notwithstanding the occurrence of a Change of Control, the Company shall not be obligated to make a Change of Control Offer in the event it has delivered a notice
of redemption (which is or has become unconditional) with respect to all of the outstanding Notes as provided under Section 3.07. A Change of Control Offer may be made in advance of a Change of Control and conditioned upon such Change of
Control if a definitive agreement is in place for the Change of Control at the time of making the Change of Control Offer. The provisions under the Indenture relating to the Company’s obligation to make an offer to repurchase the Notes as a
result of a Change of Control may be waived or modified with the written consent of the Holders of a majority in principal amount of the Notes then outstanding. 

Section 4.16 Sale and Leaseback Transactions. The Company shall not enter into any sale and leaseback transaction; provided
that the Company may enter into a sale and leaseback transaction if: 

(i)        the Company could have: 

(1)        incurred Indebtedness in an amount equal to the Attributable Debt relating
to such sale and leaseback transaction pursuant to Section 4.09 hereof; and 

(2)        incurred a Lien to secure such Indebtedness pursuant to Section 4.12
hereof; and 

  
 44 

 (ii)        the transfer of assets in
the sale and leaseback transaction is permitted by, and the Company applies the proceeds of such transaction in compliance with, Section 3.08, Section 4.10(c) and Section 4.10(e) hereof. 

Section 4.17 Reserved. 

Section 4.18 Limitation on Issuances of Guarantees of Indebtedness. The Company shall not permit any Restricted Subsidiary,
directly or indirectly, to Guarantee or pledge any assets to secure the payment of any other Indebtedness of the Company unless such Subsidiary simultaneously executes and delivers a supplemental indenture to the Indenture providing for the
Guarantee of the payment of the Notes by such Subsidiary for so long as such Guarantee of or pledge to secure the payment of such other Indebtedness remains in effect, which Guarantee shall be senior to or pari passu with such Subsidiary’s
Guarantee of or pledge to secure such other Indebtedness. Notwithstanding the foregoing, any Guarantee by a Subsidiary of the Notes shall provide by its terms that it shall be automatically and unconditionally released and discharged upon any sale,
exchange or transfer, to any Person other than a Subsidiary of the Company, of all of the Company’s stock in, or all or substantially all the assets of, such Subsidiary, which sale, exchange or transfer is made in compliance with the applicable
provisions of the Indenture. 
 Section 4.19 Effectiveness of Covenants. The covenants described under Sections 4.07, 4.08,
4.09, 4.10, 4.11, 4.13, 4.18 and Section 5.01(ii)(4) (collectively, the “Suspended Covenants”) shall no longer be in effect if on any date the Company attains Investment Grade Status and no Default or Event of Default shall
have occurred and be continuing. If at any time the Company’s credit rating is downgraded from Investment Grade Status, then the Suspended Covenants shall thereafter be reinstated as of and from the date of such rating downgrade, unless and
until the Company subsequently attains Investment Grade Status (in which event the Suspended Covenants shall again no longer be in effect for such time that the Company maintains Investment Grade Status). Calculations under the reinstated covenant
in Section 4.07 hereof will be made as if such covenant had been in effect since the date hereof except that no Default will be deemed to have occurred solely by reason of a Restricted Payment made while Section 4.07 hereof was suspended.
Notwithstanding the reinstatement of the Suspended Covenants, no Default, Event of Default or breach of any kind shall be deemed to exist under the Indenture with respect to the Suspended Covenants based on, and none of the Company or any of its
Subsidiaries shall bear any liability for, any actions taken or events occurring after the Company attains Investment Grade Status and before any reinstatement of such Suspended Covenants as provided above, or any actions taken at any time pursuant
to any contractual obligation arising prior to such reinstatement, regardless of whether such actions or events would have been permitted if the applicable Suspended Covenants remained in effect during such period.

(v)        default under any Indebtedness for money borrowed by the Company or any of
its Significant Subsidiaries, or the payment of which is Guaranteed by the Company or any of its Significant Subsidiaries, whether such Indebtedness or Guarantee now exists, or is created after the date hereof, which default: 

(1)        is caused by a failure to pay principal of or premium, if any, or interest
on the Indebtedness prior to the expiration of the grace period provided in such Indebtedness on the date of the default (a “Payment Default”); or 

(2)        results in the acceleration of the Indebtedness prior to its express
maturity, 
 and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such
Indebtedness under which there has been a Payment 

  
 47 

 
Default or the maturity of which has been so accelerated, aggregates $40.0 million or more; 

(vi)        failure by the Company or any of its Significant Subsidiaries to pay
final judgments aggregating (net of amounts covered by insurance policies) in excess of $40.0 million, which judgments are not paid, discharged or stayed for a period of 60 days; 

(vii)        the Company or any of its Restricted Subsidiaries pursuant to or within
the meaning of Bankruptcy Law: 
 (1)        commences a voluntary case, 

(2)        consents to the entry of an order for relief against it in an involuntary
case, 
 (3)        consents to the appointment of a custodian of it or for all or
substantially all of its property, 
 (4)        makes a general assignment for the
benefit of its creditors, or 
 (5)        generally is not paying its debts as

Subsidiaries; 
 and the order or decree remains unstayed and in effect for 60 consecutive days. 

(b)        A Default under Section 6.01(a)(iv) shall not constitute an Event of Default until
the Trustee or the Holders of 25% in principal amount of the outstanding Notes notify the Company of the Default and the Company does not cure such Default within the time specified after receipt of such notice. 

Section 6.02 Acceleration. If any Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in
principal amount at maturity of the then outstanding Notes may declare all the principal of, and accrued and unpaid interest, if any, on such Notes to be due and payable immediately. Notwithstanding the foregoing, in the case of an Event of Default
arising from Section 6.01(a)(vii) or Section 6.01(a)(viii), with respect to the Company, all outstanding Notes shall be due and payable without further action or notice. Holders may not enforce the Indenture or the Notes except as provided
in the Indenture. Subject to certain limitations, Holders of a majority in principal amount at maturity of the then outstanding Notes may direct the Trustee in its exercise of any trust or power. 

  
 48 

 Section 6.03 Other Remedies. (a) If an Event of Default occurs and is
continuing, the Trustee may pursue any available remedy to collect the payment of principal of, premium, if any, and interest on the Notes or to enforce the performance of any provision of the Notes or the Indenture. 

(b)        The Trustee may maintain a proceeding even if it does not possess any of the Notes or does
not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder of the Notes in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or
acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law. 
 Section 6.04 Waiver of Past
Defaults. Holders of not less than a majority in aggregate principal amount of the then outstanding Notes by notice to the Trustee may on behalf of the Holders of all of the Notes waive an existing Default or Event of Default and its
consequences hereunder, except a continuing Default or Event of Default in the payment of the principal of, premium, if any, or interest on, the Notes (including in connection with an offer to purchase) (provided, however, that the
Holders of a majority in aggregate principal amount of the then outstanding Notes may rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration). 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 impair any right consequent thereon. 

Section 6.05 Control by Majority. Holders of a majority in principal amount of the then outstanding Notes may 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 it. However, the Trustee may refuse to follow any direction that conflicts with law or the Indenture that
the Trustee determines may be unduly prejudicial to the rights of other Holders of Notes or that may involve the Trustee in personal liability. Prior to taking any action hereunder, the Trustee shall be entitled to indemnification satisfactory to it
in its sole discretion against all losses and expenses caused by taking or not taking such action. 
 Section 6.06 Limitation on
Suits. (a) A Holder of a Note may pursue a remedy with respect to the Indenture or the Notes only if: 

(i)        the Holder of a Note gives to the Trustee written notice of a continuing
Event of Default; 
 (ii)        the Holders of at least 25% in principal amount of
the then outstanding Notes make a written request to the Trustee to pursue the remedy; 

(iii)        such Holders of Notes offer and, if requested, provide to the Trustee
indemnity satisfactory to the Trustee against any loss, liability or expense; 

(iv)        the Trustee does not comply with the request within 60 days after receipt
of the request and the offer and, if requested, the provision of indemnity; and 

(v)        during such 60-day period the Holders of a majority in principal amount of
the then outstanding Notes do not give the Trustee a direction inconsistent with the request. 

(b)        A Holder of a Note may not use the Indenture to prejudice the rights of another Holder of
a Note or to obtain a preference or priority over another Holder of a Note. 

  
 49 

 Section 6.07 Rights of Holders of Notes to Receive Payment. Notwithstanding any other
provision of the Indenture, the right of any Holder of a Note to receive payment of principal of, premium, if any, and interest on the Note, on or after the respective due dates expressed in the Note (including in connection with an offer to
purchase), or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder. 

Section 6.08 Collection Suit by Trustee. If an Event of Default specified in Section 6.01(a)(i) or Section 6.01(a)(ii)
occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Company for the whole amount of principal of, premium, if any, and interest remaining unpaid on the Notes and
interest on overdue principal and, to the extent lawful, interest and 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. 
 Section 6.09 Trustee May File Proofs of Claim. The Trustee is authorized to file such proofs
of claim and 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
the Holders allowed in any judicial proceedings relative to the Company (or any other obligor upon the Notes), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or other property payable
or deliverable on any such claims and any Custodian 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 to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof. To the extent
that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof out of the estate in any such proceeding, shall be denied
for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in
liquidation or under any plan of reorganization or arrangement or otherwise. 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, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 

Section 6.10 Priorities. (a) If the Trustee collects any money pursuant to this Article 6, it shall pay out the money in the
following order: 
 First: to the Trustee, its agents and attorneys for amounts due under Section 7.07 hereof, including payment
of all compensation, expense and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection; 

Second: to Holders for amounts due and unpaid on the Notes for principal, premium, if any, and interest, ratably, without preference or
priority of any kind, according to the amounts due and payable on the Notes for principal, premium, if any and interest, respectively; and 

Third: to the Company or to such party as a court of competent jurisdiction shall direct. 

(b)        The Trustee may fix a record date and payment date for any payment to Holders pursuant to
this Section 6.10. 

  
 50 

 Section 6.11 Undertaking for Costs. In any suit for the enforcement of any right or
remedy under the Indenture or in any suit against the Trustee for any action taken or omitted by it as a Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and
the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party
litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in principal amount of the then outstanding Notes. 

ARTICLE 7 
 TRUSTEE

 Section 7.01 Duties of Trustee. (a) If an Event of Default has occurred and is continuing, the Trustee shall
exercise the rights and powers vested in it by the Indenture, and use the same degree of care and skill in its exercise thereof as a prudent Person would exercise or use under the circumstances in the conduct of such Person’s own affairs. 

(b)         Except during the continuance of an Event of Default: 

(i)         the Trustee undertakes to perform such duties and only such duties as are

(ii)         in the absence of bad faith on its part, the Trustee may conclusively
rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of the Indenture. However, the Trustee shall examine the
certificates and opinions to determine whether or not they conform to the requirements of the Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein). 

(c)         The Trustee may not be relieved from liability for its own grossly negligent action, its
own grossly negligent failure to act, or its own willful misconduct, except that: 

(i)         this paragraph does not limit the effect of Section 7.01(b); 

(ii)         the Trustee shall not be liable for any error of judgment made in good
faith by a Responsible Officer unless it is proved that the Trustee was grossly negligent in ascertaining the pertinent facts; and

omits to take in good faith in accordance with a direction received by it pursuant to Section 6.05 hereof.

be segregated from other funds except to the extent required by law.

(h)        Every provision of the Indenture relating to the conduct or affecting the liability of or
affording protection to the Trustee shall be subject to the provisions of this Section 7.01 and to the provisions of the TIA. 

Section 7.02 Rights of Trustee. (a) The Trustee may conclusively rely upon any document believed by it to be genuine and to
have been signed or presented by the proper Person. The Trustee need not investigate any fact or matter stated in the document.

Certificate or an Opinion of Counsel or both. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on the Officers’ Certificate or Opinion of Counsel. 

(c)        The Trustee may act through agents or attorneys and shall not be responsible for the
misconduct or negligence of any agent or attorney appointed with due care. 
 (d)        The

misconduct or gross negligence.

bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, approval, bond, debenture, note or other paper or document. 

(g)        The Trustee shall not be deemed to have notice or charged with knowledge of any Default or
Event of Default unless a Responsible Officer of the Trustee has actual knowledge thereof or unless written notice of any event which is in fact such a default is received from the Company or any Holders by the Trustee at the Corporate Trust Office
of the Trustee, and such notice references the Notes and the Indenture. 
 (h)        The rights,
privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to and shall be enforceable by, the Trustee in each of its capacities hereunder, and to each agent,

 (i)        The Trustee shall be under no
obligation to exercise any of the rights or powers vested in it by the Indenture at the request or direction of any of the Holders pursuant to the Indenture, unless such Holders shall have offered to the Trustee security or indemnity satisfactory to
the Trustee against the costs, expenses and liabilities which might be incurred by the Trustee in compliance with such request or direction. 

  
 52 

 (j)         The Trustee may from time to time request
that the Company deliver an Officers’ Certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to the Indenture, which Officers’ Certificate may be signed by
any persons authorized to sign an Officers’ Certificate, including any person specified as so authorized in any such certificate previously delivered and not superseded. 

(k)         The permissive right of the Trustee to take any action under the Indenture shall not be
construed as a duty to so act.

liable for any special, indirect or consequential loss or damage of any kind whatsoever (including loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action.

 Section 7.03 Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the owner or
pledgee of the Notes and may otherwise deal with the Company or any Affiliate of the Company with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest it must eliminate such
conflict within 90 days, apply to the SEC for permission to continue as trustee or resign. Any Agent may do the same with like rights and duties. The Trustee is also subject to Section 7.10 and Section 7.11 hereof. 

Section 7.04 Trustee’s Disclaimer. The Trustee shall not be responsible for and makes no representation as to the validity or
adequacy of the Indenture or the Notes, it shall not be accountable for the Company’s use of the proceeds from the Notes, it will not be responsible for the use or application of any money received by any Paying Agent (other than itself as
Paying Agent), and it shall not be responsible for any statement in the Indenture, in the Notes, or in any document executed in connection with the sale of the Notes, other than those set forth in the Trustee’s certificate of authentication.

 Section 7.05 Notice of Defaults. If a Default or Event of Default occurs and is continuing and if it is actually known to a
Responsible Officer of the Trustee, the Trustee shall send to each Holder a notice of the Default within 90 days after it occurs. Except in the case of a Default or an Event of Default in payment of the principal amount of (or the portion thereby
specified in the Notes), premium, if any, or accrued and unpaid interest on any Note, the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the
interests of Holders. 
 Section 7.06 Reports by Trustee to Holders. (a) Within 60 days after each October 15,
beginning with the first October 15 after the date hereof, for so long as the Notes remain outstanding, the Trustee shall send to the Holders a brief report dated as of such reporting date that complies with TIA § 313(a) (but if no event
described in TIA § 313(a) has occurred within the 12 months preceding the reporting date, no report need be transmitted). The Trustee also shall comply with TIA § 313(b). The Trustee shall also transmit all reports as required by TIA
§ 313(c). 
 (b)         A copy of each report at the time of its sending to the Holders shall
be sent to the Company and filed with the SEC and each stock exchange on which the Notes are listed in accordance with TIA § 313(d). The Company shall promptly notify the Trustee when the Notes are listed on any stock exchange. 

Section 7.07 Compensation and Indemnity. (a) The Company shall pay to the Trustee from time to time such compensation for its
services as the Company and the Trustee shall from time to time agree in writing. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee upon request
for all reasonable out-of-pocket

the delivery of an Opinion of Counsel or otherwise in addition to the compensation for its services. Such expenses shall include the reasonable compensation and expenses, disbursements and advances of the Trustee’s agents, counsel, accountants
and experts. The Company shall indemnify the Trustee against any and all loss, liability or expense (including reasonable attorneys’ fees and disbursements) incurred by or in connection with the administration of this trust and the performance
of its duties hereunder, including the costs and expenses of enforcing the Indenture (including this Section 7.07) and of defending itself against any claims (whether asserted by any Holder, the Company or otherwise). The Trustee shall notify
the Company of any claim for which it may seek indemnity promptly upon obtaining actual knowledge thereof; provided, however, that any failure so to notify the Company shall not relieve the Company of its indemnity obligations
hereunder. The Company need not reimburse any expense or indemnify against any loss, liability or expense incurred by an indemnified party through such party’s own willful misconduct, gross negligence or bad faith. 

(b)         To secure the Company’s payment obligations in this Section 7.07, the Trustee
shall have a Lien prior to the Notes on all money or property held or collected by the Trustee other than money or property held in trust to pay the principal of and interest and any liquidated damages on the Notes. 

(c)         The Company’s payment obligations pursuant to this Section 7.07 shall survive
the satisfaction or discharge of the Indenture, any rejection or termination of the Indenture under any bankruptcy law or the resignation or removal of the Trustee. When the Trustee incurs expenses after the occurrence of a Default specified in
Section 6.01(a)(vii) or Section 6.01(a)(viii), the expenses are intended to constitute expenses of administration under the Bankruptcy Law. 

Section 7.08 Replacement of Trustee. (a) A resignation or removal of the Trustee and appointment of a successor Trustee shall
become effective only upon the successor Trustee’s acceptance of appointment as provided in this Section 7.08. 

(b)         The Trustee may resign at any time by so notifying the Company. The Holders of a majority
in principal amount of the then outstanding Notes may remove the Trustee and may appoint a successor Trustee. The Company shall remove the Trustee if: 

(i)         the Trustee fails to comply with Section 7.10 hereof; 

(ii)         the Trustee is adjudged a bankrupt or an insolvent or an order for
relief is entered with respect to the Trustee under any Bankruptcy Law; 

(iii)         a Custodian or public officer takes charge of the Trustee or its
property; or 
 (iv)         the Trustee otherwise becomes incapable of acting.

 (c)         If the Trustee resigns, is removed by the Company or by the Holders of a majority in
principal amount of the then outstanding Notes and such Holders do not reasonably promptly appoint a successor Trustee or if a vacancy exists in the office of Trustee for any reason (the Trustee in such event being referred to herein as the retiring
Trustee), the Company shall promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in principal amount of the then outstanding Notes may appoint a successor Trustee to replace the
successor Trustee appointed by the Company. 

  
 54 

 (d)         A successor Trustee shall deliver a written
acceptance of its appointment to the retiring Trustee and to the Company. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee
under the Indenture. The successor Trustee shall send a notice of its succession to Holders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided for in
Section 7.07. 
 (e)         If a successor Trustee does not take office within 30 days after
the retiring Trustee resigns or is removed, the retiring Trustee or the Holders of 10% in principal amount of then outstanding Notes may petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a successor
Trustee. 
 (f)         If the Trustee fails to comply with Section 7.10, after written notice
hereto, the Holders of at least 10% in principal amount of the Notes may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 

(g)         Notwithstanding the replacement of the Trustee pursuant to this Section 7.08, the
Company’s obligations under Section 7.07 shall continue for the benefit of the retiring Trustee. 
 Section 7.09 Successor
Trustee by Merger, etc. If the Trustee consolidates with, merges or converts into, or transfers all or substantially all its corporate trust business or assets to, another corporation or banking association, the resulting, surviving or
transferee corporation without any further act shall be the successor Trustee. In case at the time such successor or successors by merger, conversion or consolidation to the Trustee shall succeed to the trusts created by the Indenture any of the
Notes shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee, and deliver such Notes so authenticated; and if at that time any of the Notes shall not
have been authenticated, any such successor to the Trustee may authenticate such Notes either in the name of any predecessor hereunder or in the name of the successor to the Trustee; and in all such cases such certificates shall have the full force
which it is anywhere in the Notes or in the Indenture provided that the certificate of the Trustee shall have. 
 Section 7.10

 ARTICLE 8 

LEGAL DEFEASANCE AND COVENANT DEFEASANCE 

Section 8.01 Option to Effect Legal Defeasance or Covenant Defeasance. The Company may, at the option of the Board of Directors
evidenced by a Board Resolution set forth in an Officers’ Certificate, at any time, elect to have either Section 8.02 or 8.03 hereof be applied to all outstanding Notes upon compliance with the conditions set forth below in this Article 8.

 Section 8.02 Legal Defeasance and Discharge. (a) Upon the Company’s exercise under Section 8.01 hereof of the
option applicable to this Section 8.02, the Company shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to have been discharged from its obligations with respect to all outstanding Notes on the
date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, 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 8.05 hereof and the other Sections of the Indenture referred to in (i) and (ii) below, and to have satisfied all its
other obligations under such Notes and the Indenture (and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following provisions which shall survive until otherwise
terminated or discharged hereunder: 
 (i)        the rights of Holders of
outstanding Notes to receive payments in respect of the principal of, premium, if any, and interest on the Notes when such payments are due from the trust referred to below; 

(ii)        the Company’s obligations with respect to the Notes concerning
issuing temporary Notes, registration of Notes, mutilated, destroyed, lost or stolen Notes and the maintenance of an office or agency for payment and money for security payments held in trust; 

(iii)        the rights, powers, trusts, duties and immunities of the Trustee, and
the Company’s obligations in connection therewith; and 
 (iv)        the
Legal Defeasance provisions of the Indenture. 
 (b)        Subject to compliance with this Article
8, the Company may exercise its option under this Section 8.02 notwithstanding the prior exercise of its option under Section 8.03 hereof. 

Section 8.03 Covenant Defeasance. Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this
Section 8.03, the Company shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from its obligations under the covenants contained in Sections 4.03, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13,
4.15, 4.16 and 4.18 hereof and Section 5.01(ii)(4) hereof with respect to the outstanding Notes on and after the date the conditions set forth in Section 8.04 are satisfied (hereinafter, “Covenant Defeasance”), and the
Notes shall thereafter be deemed not “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 (it being understood that such Notes shall not be deemed outstanding for accounting purposes). For this purpose, 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 

  
 56 

 
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 Section 6.01 hereof, but, except as specified
above, the remainder of the Indenture and such Notes shall be unaffected thereby. In addition, upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03 hereof, subject to the satisfaction of
the conditions set forth in Section 8.04 hereof, Section 6.01(a)(iii) through Section 6.01(a)(vi) hereof shall not constitute Events of Default. 

Section 8.04 Conditions to Legal or Covenant Defeasance. (a) The following shall be the conditions to the application of
either Section 8.02 or 8.03 hereof to the outstanding Notes: 
 (i)        the
Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders, cash in United States Dollars, non-callable Government Securities, or a combination thereof, in such amounts as shall be sufficient, in the opinion of a
nationally recognized firm of independent public accountants, to pay the principal of, premium, if any, and interest on the outstanding Notes on the Stated Maturity or on the redemption date, as the case may be, and the Company must specify whether
the Notes are being defeased to maturity or to a particular redemption date; 

(ii)        in the case of Legal Defeasance, the Company shall have delivered to the
Trustee an Opinion of Counsel of a nationally recognized law firm in the United States confirming that: 

(1)        the Company has received from, or there has been published by, the
Internal Revenue Service a ruling; or 
 (2)        since the date hereof, there
has been a change in the applicable federal income tax law, 
 in either case to the effect that, and based thereon such Opinion of Counsel
shall confirm that, the Holders of the outstanding Notes shall not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and shall be subject to 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; 

(iii)        in the case of Covenant Defeasance, the Company shall have delivered to
the Trustee an Opinion of Counsel of a nationally recognized law firm in the United States confirming that the Holders of the outstanding Notes shall not recognize income, gain or loss for federal income tax purposes as a result of such Covenant
Defeasance and shall be subject to 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; 

(iv)        no Default or Event of Default shall have occurred and be continuing
either: 
 (1)        on the date of such deposit, other than a Default or Event of
Default resulting from the borrowing of funds to be applied to such deposit; or 

(2)        insofar as Events of Default from bankruptcy or insolvency events with
respect to the Company are concerned, at any time in the period ending on the 91st day after the date of deposit; 

  
 57 

 (v)        such Legal Defeasance or
Covenant Defeasance shall not result in a breach or violation of, or constitute a default under any material agreement or instrument, other than the Indenture, to which the Company or any of its Restricted Subsidiaries is a party or by which the
Company or any of its Restricted Subsidiaries is bound; 
 (vi)        the Company
must have delivered to the Trustee an Opinion of Counsel to the effect that after the 91st day following the deposit, the trust funds shall not be subject to the effect of any applicable bankruptcy, insolvency, reorganization or similar laws
affecting creditors’ rights generally; 
 (vii)        the Company must
deliver to the Trustee an Officers’ Certificate stating that the deposit was not made by the Company with the intent of preferring the Holders over the other creditors of the Company with the intent of defeating, hindering, delaying or
defrauding creditors of the Company or others; and 
 (viii)        the Company
must deliver to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for relating to the Legal Defeasance or the Covenant Defeasance have been complied with. 

Section 8.05 Deposited Money and Government Securities to be Held in Trust; Other Miscellaneous Provisions. (a) Subject to
Section 8.06 hereof, all money and non-callable Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.05, the “Trustee”)
pursuant to Section 8.04 hereof 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 the Indenture, to the payment, either directly or through any Paying
Agent (including the Company acting as 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, premium, if any, and interest, but such money need not be segregated
from other funds except to the extent required by law. 
 (b)        The Company shall pay and
indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or non-callable Government Securities deposited pursuant to Section 8.04 hereof 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. 

(c)        Anything in this Article 8 to the contrary notwithstanding, the Trustee shall deliver or
pay to the Company from time to time upon the request of the Company any money or non-callable Government Securities held by it as provided in Section 8.04 hereof which, in the opinion of a nationally recognized firm of independent public
accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.04(a) hereof), are in excess of the amount thereof that would then be required to be deposited to effect an
equivalent Legal Defeasance or Covenant Defeasance. 
 Section 8.06 Repayment to Company. 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, premium, if any, or interest on any Note and remaining unclaimed for two years after such principal, and premium, if any, or interest has become due and
payable shall be paid to the Company on its request or (if then held by the Company) shall be discharged from such trust; and the Holder of such Note shall thereafter 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; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment,
may at the expense of the Company cause to be published once, in the New York Times and The Wall Street 

  
 58 

 
Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such notification or
publication, any unclaimed balance of such money then remaining shall be repaid to the Company. 
 Section 8.07 Reinstatement.
If the Trustee or Paying Agent is unable to apply any United States dollars or non-callable Government Securities in accordance with Section 8.02 or 8.03 hereof, as the case may be, 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 the Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to
Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.02 or 8.03 hereof, as the case may be; provided, however, that, if the Company makes
any payment of principal of, 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 held by the
Trustee or Paying Agent. 
 ARTICLE 9 

AMENDMENT, SUPPLEMENT AND WAIVER 

Section 9.01 Without Consent of Holders of Notes. (a) Notwithstanding Section 9.02 of the Indenture, the Company and the
Trustee may amend or supplement the Indenture or the Notes without the consent of any Holder of the Notes to: 

(i)        cure any ambiguity, omission, defect or inconsistency; 

(ii)        provide for uncertificated Notes in addition to or in place of
Certificated Notes; 
 (iii)        provide for the assumption of the
Company’s obligations to Holders of Notes in the case of a merger or consolidation; 

(iv)        make any change that would provide any additional rights or benefits to
the Holders of Notes or that does not adversely affect the legal rights under the Indenture of any such Holder in any material respect; 

(v)        comply with requirements of the SEC in order to effect or maintain the
qualification of the Indenture under the TIA; or 
 (vi)        conform a provision
of the Base Indenture or this Supplemental Indenture to the extent such provision was intended to be a substantially verbatim recitation of the applicable provision under the caption “Description of Notes” in the Prospectus. 

For the avoidance of doubt, nothing in this Supplemental Indenture shall be construed to require any consent of any Holder to amend or
supplement the Base Indenture in any manner that does not relate to the Notes. 
 (b)        Upon
the request of the Company accompanied by a Board Resolution authorizing the execution of any such amended or supplemental indenture, and upon receipt by the Trustee of the documents described in Section 7.02 hereof, the Trustee shall join with
the Company in the execution of any amended or supplemental indenture authorized or permitted by the terms of the 

  
 59 

 
Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to enter into such amended or supplemental
indenture that affects its own rights, duties or immunities under the Indenture or otherwise. 
 Section 9.02 With Consent of
Holders of Notes. (a) Except as provided below in this Section 9.02, the Company and the Trustee may amend or supplement the Indenture (including Section 3.08, 4.10 and 4.15 hereof) and the Notes with the consent of the Holders of
at least a majority in principal amount of the Notes then outstanding, voting as a single class (including consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes), and, subject to Sections 6.04 and 6.07
hereof, any existing Default or Event of Default (other than a Default or Event of Default in the payment of the principal of, premium, if any, or interest on the Notes, except a Payment Default resulting from an acceleration that has been
rescinded) or compliance with any provision of the Indenture or the Notes may be waived with the consent of the Holders of a majority in principal amount of the then outstanding Notes, voting as a single class (including consents obtained in
connection with a tender offer or exchange offer for, or purchase of, the Notes). Section 2.09 hereof shall determine which Notes are considered to be “outstanding” for purposes of this Section 9.02. 

(b)        Upon the request of the Company accompanied by a Board Resolution authorizing the
execution of any such amended or supplemental indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee of the documents described in
Section 7.02 hereof, the Trustee shall join with the Company in the execution of such amended or supplemental indenture unless such amended or supplemental indenture directly affects the Trustee’s own rights, duties or immunities under the
Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such amended or supplemental indenture. 

(c)        It shall not be necessary for the consent of the Holders of Notes under this
Section 9.02 to approve the particular form of any proposed amendment or waiver, but it shall be sufficient if such consent approves the substance thereof. 

(d)        After an amendment, supplement or waiver under this Section 9.02 becomes effective,
the Company shall send to the Holders of Notes affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to send such notice, or any defect therein, shall not, however, in any way impair or affect
the validity of any such amended or supplemental indenture or waiver. Subject to Sections 6.04 and 6.07 hereof, the Holders of a majority in aggregate principal amount of the Notes then outstanding, voting as a single class, may waive compliance in
a particular instance by the Company with any provision of the Indenture or the Notes. However, without the consent of each Holder affected, an amendment or waiver under this Section 9.02 or otherwise may not (with respect to any Notes held by
a non-consenting Holder): 
 (i)        reduce the principal amount of Notes whose
Holders must consent to an amendment, supplement or waiver; 
 (ii)        reduce
the principal of or change the fixed maturity of any Note or alter the provisions with respect to the redemption (other than the notice period), but not any required repurchase in connection with an Asset Sale Offer or Change of Control Offer, of
the Notes; 
 (iii)        reduce the rate of or extend the time for payment of
interest on any Note; 

  
 60 

 (iv)        waive a Default or Event of
Default in the payment of principal of or premium, if any, or interest on the Notes, excluding a rescission of acceleration of the Notes by the Holders of at least a majority in aggregate principal amount of the Notes and a waiver of the Payment
Default that resulted from such acceleration; 
 (v)        make any Note payable
in money other than that stated in the Notes; 
 (vi)        make any change in the
provisions of the Indenture relating to waivers of past Defaults or the rights of Holders of Notes to receive payments of principal of or premium, if any, or interest on the Notes; 

(vii)        waive a redemption payment, but not any payment upon a required
repurchase in connection with an Asset Sale Offer or Change of Control Offer, with respect to any Note; or 

(viii)        make any change in the foregoing amendment and waiver provisions. 

Section 9.03 Compliance with Trust Indenture Act. Every amendment or supplement to the Indenture or the Notes shall be set forth
in an amended or supplemental indenture that complies with the TIA as then in effect. 
 Section 9.04 Revocation and Effect of
Consents. Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of a Note and every subsequent Holder of a Note or portion of a Note that evidences the same debt
as the consenting Holder’s Note, even if notation of the consent is not made on any Note. However, any such Holder of a Note or subsequent Holder of a Note may revoke the consent as to its Note if the Trustee receives written notice of
revocation before the date the waiver, supplement or amendment becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder. 

Section 9.05 Notation on or Exchange of Notes. (a) The Trustee may place an appropriate notation about an amendment,
supplement or waiver on any Note thereafter authenticated. The Company in exchange for all Notes may issue and the Trustee shall, upon receipt of a Company Order, authenticate new Notes that reflect the amendment, supplement or waiver. 

(b)        Failure to make the appropriate notation or issue a new Note shall not affect the validity
and effect of such amendment, supplement or waiver. 
 Section 9.06 Trustee to Sign Amendments, etc. The Trustee shall sign any
amended or supplemental indenture authorized pursuant to this Article 9 if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. The Company may not sign an amended or supplemental
indenture until the Board of Directors approves it. In executing any amended or supplemental indenture, the Trustee shall be entitled to receive and (subject to Section 7.01 hereof) shall be fully protected in relying upon an Officer’s
Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by the Indenture.

deposited with the Trustee as trust funds in trust solely for the benefit of the Holders, cash in U.S. dollars, non-callable 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 principal and premium, if any, and accrued interest to the date of maturity or redemption on all Notes not delivered to the Trustee for cancellation; 

(ii)        the Company has paid or caused to be paid all sums payable by it under
the Indenture; and

Counsel to the Trustee stating that all conditions precedent to satisfaction and discharge have been satisfied.

CROWN CASTLE INTERNATIONAL CORP., a corporation duly organized and existing under the laws of the State of Delaware (herein called the
“Company,” which term includes any successor Person under the Indenture hereinafter defined), for value received, hereby promises to pay to CEDE & CO., or registered assigns, the principal sum of

“Payment Date”) in each year, commencing October 15, 2014, at the rate of 4.875% per annum, until the principal hereof is paid or made available for payment.

 The interest so payable, and punctually paid or duly provided for, on any Payment Date will, as provided in the Indenture, be paid to the Person in
whose name this Note is registered at the close of business on the regular record date for such interest, which shall be April 1 or October 1, as the case may be, next preceding such Payment Date or, if such record date is not a Business
Day, at the close of business of the immediately succeeding Business Day. A “Business Day” shall mean any day other than a Saturday, Sunday or a day on which banking institutions in the City of New York or at a place of payment are
authorized by law, regulation or executive order to remain closed. If a payment date is not 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 on
such payment for the intervening period. Any such interest not so punctually paid or duly provided for will forthwith cease to be payable to the Holder on such regular record date and shall be paid to the Person in whose name this Note is registered
at the close of business on a subsequent special record date, which date shall be the fifteenth day next preceding the date fixed by the Company for the payment of defaulted interest or the next succeeding Business Day if such date is not a Business
Day. At least 30 days before the special record date, the Company shall send or cause to be sent to each Holder, with a copy to the Trustee, a notice that states the special record date, the payment date and the amount of defaulted interest and the
amount of interest payable on such defaulted interest, if any, to be paid. 
 If a Holder has given wire transfer instructions to the Company, the Company
will make all payments of principal, premium and interest, if any, on that Holder’s Notes in accordance with those instructions. All other payments on the Notes will be made at the office or agency of the Paying Agent and Registrar for the
Notes within the City and State of New York unless, with respect to such other payments, the Company elects to make interest payments by check mailed to the Holders at their address set forth in the register of Holders. Interest will be computed on
the basis of a 360-day year composed of twelve 30-day months.

 [FORM OF REVERSE OF NOTE] 

 

	1.	Notes. 

 This Note is one of a duly authorized issue of senior notes of the Company (herein called the
“Notes”), issued and to be issued in one or more series under the First Supplemental Indenture, dated as of April 15, 2014 (the “Supplemental Indenture”), to the Indenture dated as of April 15, 2014 (the
“Base Indenture” and, together with the Supplemental Indenture, the “Indenture”) between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee (herein called the “Trustee,”
which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee, and the
Holders and of the terms upon which the Notes are, and are to be, authenticated and delivered. This Note is one of the series designated on the face hereof as “4.875% Senior Notes due 2022,” issued in an initial aggregate principal amount
of $850,000,000. All terms used in this Note which are defined in the Indenture shall have the meanings assigned to them in the Indenture. 
  

	2.	No Sinking Fund 

 No sinking fund is provided for the Notes. 

 

	3.	Optional Redemption. 

 (a) At the Company’s option, the Notes may be redeemed at any time
in whole or in part. If the Company elects to redeem the Notes, the Company will pay a redemption price equal to the greater of the following amounts, plus, in each case, accrued and unpaid interest thereon to but excluding the redemption date:
(1) 100% of the aggregate principal amount of the Notes to be redeemed or (2) the sum of the present values of the Remaining Scheduled Payments. In determining the present values of the Remaining Scheduled Payments, the Company will
discount such payments to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) using a discount rate equal to the Treasury Rate plus 50 basis points. 

(b) During the period after the date of original issuance of the Notes until April 15, 2017, the Company may on any one or more occasions
redeem up to 35% of the aggregate principal amount of Notes issued, including any Additional Notes issued pursuant to the Indenture, at a redemption price of 104.875% of the principal amount of the Notes to be redeemed on the redemption date with
the net cash proceeds of one or more Equity Offerings; provided that: 
 (1) at least 65% of the aggregate principal amount of Notes
issued, including any Additional Notes issued pursuant to the Indenture, remains outstanding immediately after the occurrence of such redemption, excluding Notes held by the Company or any of its Subsidiaries; and 

(2) the redemption occurs within 120 days of the date of the closing of the Equity Offering. 

 

	4.	Selection and Notice of Redemption. 

 (a) If less than all of the Notes are to be redeemed at
any time, the Notes to be redeemed will be selected in accordance with the procedures of the Depositary. 
 (b) No Notes of $2,000 of
principal amount at maturity or less will be redeemed in part. Notices of redemption will be sent at least 30 but not more than 60 days before the redemption date to each Holder of Notes to be redeemed at its registered address. Notices of
redemption may be conditional. 

  
 5 

	5.	Repurchase at Option of Holder. 

 (a) If a Change of Control occurs, each Holder will have the
right to require the Company to repurchase all or any part, equal to $2,000 or an integral multiple of $1,000, of such Holder’s Notes (the “Change of Control Offer”). The offer price in any Change of Control Offer will be
payable in cash and will be 101% of the aggregate principal amount of any Notes repurchased plus accrued and unpaid interest on the Notes, if any (subject to the right of Holders of record on the relevant record date to receive interest due on the
relevant interest payment date), to the date of purchase (the “Change of Control Payment”). Within 30 days following any Change of Control, the Company will send a notice to each Holder describing the transaction or transactions
that constitute the Change of Control and offering to repurchase Notes on the date specified in the notice (the “Change of Control Payment Date”). The Change of Control Payment Date will be no earlier than 30 days and no later than
60 days from the date the notice is sent, pursuant to the procedures required by the Indenture and described in such notice. 
 (b) Any Net
Proceeds from Asset Sales that are not applied or invested as provided in the Indenture (whether by election or the passage of time) will be deemed to constitute Excess Proceeds. When the aggregate amount of Excess Proceeds exceeds $25.0 million,
the Company will be required to make an offer to all Holders, and all holders of other senior Indebtedness of the Company containing provisions similar to those set forth in the Indenture with respect to offers to purchase or redeem with the
proceeds of sales of assets, to purchase the maximum principal amount of Notes and such other senior Indebtedness of the Company that may be purchased out of the Excess Proceeds. The offer price in any Asset Sale Offer will be payable in cash and
will be 100% of the principal amount of any Notes, plus accrued and unpaid interest, if any, to the date of purchase. In the case of any other senior Indebtedness, the offer price will be 100% of the principal amount (or accreted value, as
applicable) of the Indebtedness plus accrued and unpaid interest thereon, if any, to the date of purchase. Each Asset Sale Offer will be made in accordance with the procedures set forth in the Indenture and the other senior Indebtedness of the
Company. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company may use the remaining Excess Proceeds for any purpose not otherwise prohibited by the Indenture. If the aggregate principal amount of Notes and the other
senior Indebtedness of the Company tendered into the Asset Sale Offer exceeds the amount of Excess Proceeds, the Company will select the Notes to be purchased on a pro rata basis. Upon completion of the Asset Sale Offer, the amount of Excess
Proceeds will be reset at zero. 
  

	6.	Acceleration Upon Event of Default. 

 (a) If any Event of Default occurs and is continuing, the
Trustee or the Holders of at least 25% in principal amount at maturity of the then outstanding Notes may declare all the Notes 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, with respect to the Company, all outstanding Notes will become due and payable without further action or notice. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. Subject to
certain limitations, Holders of a majority in principal amount at maturity of the then outstanding Notes may direct the Trustee in its exercise of any trust or power. 

(b) The Holders of a majority in aggregate principal amount at maturity of the Notes then outstanding by notice to the Trustee may on behalf
of the Holders of all Notes waive any existing Default or Event of Default and its consequences under the Indenture except a continuing Default or Event of Default in the payment of interest on, or the principal of, the Notes (provided,
however, that the Holders of a majority in aggregate principal amount of the then outstanding Notes may rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration). 

  
 6 

 (c) The Indenture provides that if a Default occurs and is continuing and is known to the
Trustee, the Trustee must send to each Holder notice of the Default within 90 days after it occurs. Except in the case of a Default in the payment of principal of or interest on any Note, the Trustee may withhold notice if and so long as a committee
of its trust officers determines that withholding notice is not opposed to the interest of the Holders. In addition, the Company is required to deliver to the Trustee, within 90 days after the end of each Fiscal Year, an Officers’ Certificate
indicating whether the signers thereof know of any Default that occurred during the previous year. The Company is also required to deliver to the Trustee, promptly after the occurrence thereof, written notice of any event that would constitute a
Default, the status thereof and what action the Company is taking or proposes to take in respect thereof. 
  

	7.	Amendment and Modification. 

 The Indenture permits, with certain exceptions as therein provided, the amendment
thereof and the modification of the rights and obligations of the Company and the rights of the Holders under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in principal amount of
the Notes at the time outstanding. The Indenture also contains provisions permitting the Holders of not less than a majority in principal amount of the Notes at the time outstanding, on behalf of the Holders of all the Notes, to waive compliance by
the Company with certain provisions of the Indenture and certain past Defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future
Holders of this Note and of any Note issued in exchange herefor or in lieu hereof whether or not notation of such consent or waiver is made upon this Note or such other Note. 
  

	8.	No Impairment of Obligation to Pay or Right to Convert. 

 No reference herein to the Indenture and no provision
of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of, premium, if any, and interest on this Note at the times, places and rate, and in the coin or
currency, herein prescribed or to convert this Note as provided in the Indenture. 
  

	9.	Transfer and Exchange. 

 As provided in the Indenture and subject to certain limitations set forth therein, the
Notes shall be transferable only upon the surrender of a Note for registration of transfer. When a Note is presented to the Registrar with a request to register a transfer, the Registrar will register the transfer as requested if the requirements of
the Indenture are satisfied. When Notes are presented to the Registrar with a request to exchange them for an equal principal amount of Notes of other denominations, the Registrar shall make the exchange as requested if the requirements of the
Indenture are met. To permit registration of transfers and exchanges, the Company will execute and the Trustee will authenticate Notes at the Registrar’s request. 
  

	10.	No Service Charge. 

 No service charge shall be made for any such registration of transfer or exchange, but the
Company or the Registrar may require payment by the Holder of a sum sufficient to pay all taxes, assessments or other governmental charges in connection therewith. 
  

	11.	Treatment as Owner. 

 Prior to the due presentation of this Note for registration of transfer, the Company, the
Trustee, the Paying Agent or the Registrar may deem and treat the Person in whose name this Note is registered as the 

  
 7 

 
absolute owner of such Note for the purpose of receiving payment of principal of and (subject to the provisions with respect to record dates) interest on such Note and for all other purposes
whatsoever, whether or not such Note is overdue, and none of the Company, the Trustee, the Paying Agent or the Registrar shall be affected by notice to the contrary. 
  

	12.	No Liability. 

 No past, present or future director, officer, employee, incorporator or stockholder of the
Company, as such, shall have any liability (except in the case of bad faith or willful misconduct) for any obligations of the Company under the Notes 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 Note waives and releases all such liability. Such waiver and release are part of the consideration for the issuance of the Notes. 
  

	13.	Governing Law. 

 THE INTERNAL LAW OF THE STATE OF NEW YORK SHALL GOVERN AND BE USED TO CONSTRUE THE INDENTURE
AND THE NOTES WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

WHEREAS, the Company intends to issue US$400,000,000 aggregate principal amount of a new series of Securities under the

 NOW,
THEREFORE, in consideration of the foregoing, the Company and the Trustee hereby agree as follows:

of the series of Notes designated as the 4.250% Notes due 2024 of the Company to be issued under the Indenture, which form, terms and provisions are set forth in the form of the Notes attached hereto as Exhibit A and in this Supplemental
Indenture. The Company may issue additional notes of the series of Notes designated as the 4.250% Notes due 2024; provided that if the additional notes are not fungible with the 4.250% Notes due 2024 for U.S. federal income tax purposes, the

ARTICLE 3 
 REDEMPTION OF
SECURITIES 
 Section 3.01    Optional Redemption. The Indenture is hereby supplemented to incorporate the
following rights of redemption solely with respect to the Notes (and not with respect to any other series of Securities): 

(a)        Optional redemption. The Company may redeem the Notes, in whole or in part, at any
time and from time to time beginning on the date that is 90 days prior to the Stated Maturity of the Notes, at its option at a Redemption Price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest on
the principal amount of the Notes being redeemed to the Redemption Date. 
 Notwithstanding the foregoing, payments of interest on the Notes
that are due and payable on or prior to the Redemption Date of the Notes will be payable to Holders of those Notes registered as such at the close of business on the Regular Record Dates, in accordance with the terms and provisions of
Section 3.07 of the Indenture. 
 Unless the Company defaults in the payment of the Redemption Price, on and after the Redemption Date
for Notes of a particular series, interest will cease to accrue on the Notes of the series called for redemption. 

(b)        Make-whole redemption. The Company may redeem the Notes, in whole or in part, at any
time and from time to time, at its option, at a Redemption Price calculated by the Company equal to the greater of (i) 100% of the then outstanding principal amount of the Notes to be redeemed, and (ii) the sum of the present values of the
remaining scheduled payments of principal and interest on the Notes to be redeemed discounted to the Redemption Date on a semiannual basis (a 360-day year consisting of twelve 30-days months) at the applicable Treasury Rate plus 25 basis points, in
each case, plus accrued and unpaid interest to the Redemption Date. 

  
 3 

 Solely for purposes of this Section 3.01(b), the following definitions will apply: 

“Comparable Treasury Issue” means the United States Treasury security selected by the Independent Investment Banker as having a
maturity comparable to the remaining term of the Notes to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to
the remaining term of such Notes. 
 “Comparable Treasury Price” means, with respect to the Redemption Date, (i) the average
of four Reference Treasury Dealer Quotations for the Redemption Date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (ii) if the Independent Investment Banker obtains fewer than four such Reference Treasury
Dealer Quotations, the average of all such Reference Treasury Dealer Quotations. 
 “Independent Investment Banker” means one of
the Reference Treasury Dealers. 
 “Reference Treasury Dealer” means J.P. Morgan Securities LLC or its affiliates which are
primary United States government securities dealers and not less than three other leading primary United States government securities dealers in New York City reasonably designated by the Company; provided, however, that if any of the foregoing
shall cease to be a primary United States government securities dealer in New York City (a “Primary Treasury Dealer”), the Company shall substitute therefor another Primary Treasury Dealer. 

“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 by such
Reference Treasury Dealer at or about 3:30 p.m., New York City time, on the third Business Day preceding such Redemption Date. 

“Treasury Rate” means, with respect to any Redemption Date, the rate per annum equal to the semi-annual equivalent yield to maturity
of the interpolated maturity (on a day count basis) of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption
Date. 
 ARTICLE 4 
 EVENTS OF

 Empresa Nacional de Electricidad S.A., a Chilean stock corporation (“sociedad anónima
abierta”) (herein called the “Company”, which term includes any successor under the Indenture hereinafter referred to), for value received, hereby promises to pay to 

Cede & Co. 
 or registered assigns, the
principal sum as set forth on the Schedule of Increases or Decreases annexed hereto at the office or agency of the Company in the Borough of Manhattan, The City of New York (the “Place of Payment”) on April 15, 2024 by wire transfer
of immediately available funds in such coin or currency of the United States of America as at the time of payment shall be legal tender for the payment of public and private debts, and to pay interest on said principal sum semiannually on
April 15 and October 15 of each year, commencing on October 15, 2014, at said office or agency, in like coin or currency, at the rate per annum specified in the title hereof, from the April 15 or October 15, as the case may
be, next preceding the date of this Note to which interest on the Notes has been paid or duly provided for (unless the date hereof is the date to which interest on the Notes has been paid or duly provided for, in which case from the date of this
Note), or, if no interest has been paid on these Notes or duly provided for, from April 15, 2014 (the “Original Issue Date”), until payment of said principal sum has been made or duly provided for. Notwithstanding the foregoing, if
the date hereof is after the March 31 or September 30 and before the next succeeding April 15 or October 15, this Note shall bear interest from such April 15 or October 15, as the case may be; provided,
however, that if the Company shall default in the payment of interest due on such April 15 or October 15, then this Note shall bear interest from the next preceding April 15 or October 15 to which interest on the Notes has
been paid or duly provided for, or, if no interest has been paid on the Notes or duly provided for, from the Original Issue Date. The interest so payable, and punctually paid or duly provided for, on any April 15 or October 15 will, except
as provided in the Indenture referred to on the reverse hereof, be paid by wire transfer of immediately available funds to the Person in whose name this Note (or one or more Predecessor Securities) is registered at the close of business on the next
preceding March 31 or September 30, as the case may be (herein called the “Regular Record Date”), whether or not a Business Day, or may, at the option of the Company, unless this Note is a Global Security, be paid by check mailed
to the registered address of such Person. Any such interest which is payable but is not so punctually paid or duly provided for, shall forthwith cease to be payable to the registered Holder on such Regular Record Date and may be paid either to the
Person in whose name this Note (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to Holders of
Notes not less than 10 days prior to such Special Record Date, or may be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which 

  
 2 

 
the Notes may be listed and upon such notice as may be required by such exchange, if such manner of payment shall be deemed practical by the Trustee, all as more fully provided in said Indenture.
Notwithstanding the foregoing, in the case of interest payable at the Stated Maturity, such interest shall be paid to the same Person to whom the principal hereof is payable. Interest shall be computed on the basis of a 360-day year of twelve 30-day
months. 
 All payments of or in respect of principal and interest in respect of this Note shall be made free and clear of, and without
withholding or deduction for or on account of, any present or future taxes, penalties, duties, fines, assessments or other governmental charges (or interest on any of the foregoing) of whatsoever nature (collectively, “Taxes”) imposed,
levied, collected, withheld or assessed by, within or on behalf of the Republic of Chile or any political subdivision or governmental authority thereof or therein having power to tax, unless such withholding or deduction is required by law. In such
event, the Company shall pay to each Holder such additional amounts (“Additional Amounts”) as may be necessary to ensure that the net amount received by Holders of the Notes after such withholding or deduction shall equal the respective
amounts of principal and interest that would have been receivable in respect of this Note in the absence of such withholding or deduction. However, the obligation of the Company to pay Additional Amounts shall not apply to: (i) any Taxes that
would not have been imposed but for (a) the presentation of this Note, where presentation is required for payment, more than 30 days after the later of (x) the date on which such payment first became due and (y) if the full amount
payable has not been received in the Place of Payment by the Trustee on or prior to such due date, the date on which, the full amount having been so received, notice to that effect shall have been given to the Holders by the Trustee, except to the
extent that the Holder would have been entitled to such Additional Amounts on presenting this Note for payment on the last day of such period of 30 days; (b) the existence of any present or former, direct or indirect, connection between the
Holder (or between a fiduciary, settler, beneficiary, member or shareholder of the Holder, if the Holder is an estate, a trust, a partnership, a limited liability company or a corporation) and the Republic of Chile (or any political subdivision or
governmental authority thereof or therein), other than the mere holding of this Note or the receipt of principal, interest, or other amounts in respect hereof; or (c) any combination of (a) and (b) above. All references to principal,
interest and other amounts payable hereunder shall be deemed to include references to any Additional Amounts which may be payable as set forth in the Indenture or in this Note. 

Reference is hereby made to the further provisions of this Note set forth on the reverse hereof, which further provisions shall for all
purposes have the same effect as if set forth at this place. 
 Unless the certificate of authentication hereon has been manually executed
by or on behalf of the Trustee under the Indenture, this Note shall not be entitled to any benefits under the Indenture, or be valid or obligatory for any purpose. 

The terms and conditions of this Note, to the extent they are inconsistent with any terms and conditions of the Indenture, shall supersede
such terms and conditions of the Indenture which shall have no force and effect with respect to this Note; except that the provisions of Section 107 of the Indenture shall not be so superseded.

 REVERSE OF NOTE 

This Note is one of the duly authorized issue of notes, debentures, bonds or other evidences of indebtedness (hereinafter called the
“Securities”) of the Company, of the series hereinafter specified, all issued or to be issued under and pursuant to the Indenture dated as of January 1, 1997, as amended and supplemented by the First Supplemental Indenture dated as of
July 24, 2009 and the Second Supplemental Indenture dated as of April 15, 2014 (as amended and supplemented, herein called the “Indenture”), duly executed and delivered by the Company and THE BANK OF NEW YORK MELLON (as successor
trustee to THE CHASE MANHATTAN BANK), as Trustee (herein called the “Trustee”), to which Indenture and any other indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights,
obligations, duties and immunities thereunder of the Trustee and any agent of the Trustee, any Paying Agent, the Company and the Holders of the Securities and the terms upon which the Securities are issued and are to be authenticated and delivered.

 The Securities may be issued in one or more series, which different series may be issued in various aggregate principal amounts, may
mature at different times, may bear interest (if any) at different rates, may be subject to different redemption provisions (if any), may be subject to different sinking, purchase or analogous funds (if any), may be subject to different covenants
and Events of Default and may otherwise vary as provided or permitted in the Indenture. This Note is one of the series of Securities of the Company issued pursuant to the Indenture and designated as 4.250% Notes Due 2024 (herein called the
“Notes”), limited in aggregate principal amount to $400,000,000. Pursuant to the terms of Section 301 of the Indenture, additional Notes of this series may be issued from time to time; provided that if the additional Notes are
not fungible with the Notes for U.S. federal income tax purposes, the additional Notes will have a separate CUSIP number. 
 The Company
may redeem the Notes, in whole or in part, at any time and from time to time, beginning on the date that is 90 days prior to the scheduled maturity of the Notes, at the Company’s option, according to the terms and provisions of
Section 1104 of the Indenture, at a Redemption Price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest on the principal amount of the Notes being redeemed to the Redemption Date. 

Notwithstanding the foregoing, payments of interest on the Notes that are due and payable on or prior to a Redemption Date for the Notes will
be payable to the Holders of such Notes registered as such at the close of business on the Regular Record Dates according to the terms and provisions of Section 307 of the Indenture. 

Unless the Company defaults in the payment of the Redemption Price, on and after the Redemption Date for the Notes, interest will cease to
accrue on the Notes called for redemption. 
 The Company may redeem the Notes, in whole or in part, at any time and from time to time, at
the Company’s option, according to the terms and provisions of Section 1104 of the Indenture, at a Redemption Price calculated by the Company equal to the greater of (1) 100% of the then outstanding principal amount of the Notes to be
redeemed, and (2) the sum of the 

  
 R-1 

 
present values of the remaining scheduled payments of principal and interest on the Notes to be redeemed discounted to the Redemption Date on a semiannual basis (assuming a 360-day year
consisting of twelve 30-day months) at the applicable Treasury Rate plus 25 basis points, in each case plus accrued and unpaid interest to the Redemption Date. 

“Comparable Treasury Issue” means the United States Treasury security selected by the Independent Investment Banker as having a
maturity comparable to the remaining term of the Notes to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to
the remaining term of such Notes. 
 “Comparable Treasury Price” means, with respect to the Redemption Date, (1) the average
of four Reference Treasury Dealer Quotations for the 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 Reference Treasury Dealer Quotations. 
 “Independent Investment Banker” means one of
the Reference Treasury Dealers. 
 “Reference Treasury Dealer” means J.P. Morgan Securities LLC or its affiliates which are
primary United States government securities dealers and not less than three other leading primary United States government securities dealers in New York City reasonably designated by us; provided, however, that if any of the foregoing shall cease
to be a primary United States government securities dealer in New York City (a “Primary Treasury Dealer”), the Company shall substitute therefor another Primary Treasury Dealer. 

“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 by such
Reference Treasury Dealer at or about 3:30 p.m., New York City time, on the third Business Day preceding such Redemption Date. 

“Treasury Rate” means, with respect to any Redemption Date, the rate per annum equal to the semi-annual equivalent yield to
maturity of the interpolated maturity (on a day count basis) of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such
Redemption Date. 
 The Company may redeem the Notes as a whole, but not in part, according to the terms and provisions of
Section 1104 of the Indenture, at a Redemption Price equal to 100% of the principal amount together with any accrued interest to the Redemption Date, only if (i) the Company certifies to the Trustee immediately prior to the giving of such
notice that it has or will become obligated to pay Additional Amounts with respect to the Notes in excess of the Additional Amounts that would be payable were payments of interest on the Notes subject to a 4.0% withholding tax (“Excess
Additional Amount”) as a result of any change in or amendment to the laws or regulations of the Republic of Chile or any political subdivision or governmental 

  
 R-2 

 
authority thereof or therein having power to tax, or any change in the application or official interpretation of such laws or regulations, which change or amendment occurs after the date of
issuance of the Notes and (ii) such obligation cannot be avoided by the Company taking reasonable measures available to it; provided, however, that no such notice of redemption shall be given earlier than 60 days prior to the
earliest date on which the Company would be obligated to pay such Excess Additional Amounts, if a payment in respect of the Notes were then due. Prior to the giving of any notice of redemption of the Notes pursuant to the Indenture, the Company
shall deliver to the Trustee an Officers’ Certificate, stating that the Company is entitled to effect such a redemption pursuant to the Indenture, and setting forth in reasonable detail a statement of the facts giving rise to such right of
redemption (together with a written Opinion of Counsel to the effect, among other things, that the Company has become obligated to pay such Excess Additional Amounts as a result of a change or amendment described herein and that the Company cannot
avoid payment of such Excess Additional Amounts by taking reasonable measures available to it and that all governmental approvals necessary for the Company to effect such redemption have been obtained and are in full force and effect or specifying
any such necessary approvals that as of the date of such opinion have not been obtained). 
 If an Event of Default with respect to the
Notes shall occur and be continuing, the principal of all of the Notes may be declared due and payable in the manner, with the effect and subject to the conditions provided in the Indenture. 

The Indenture permits, with certain exceptions as therein provided, the Company and the Trustee to enter into supplemental indentures to the
Indenture for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or modifying in any manner the rights of the Holders of the Securities of each series under the Indenture with the
consent of the Holders of not less than a majority in aggregate principal amount of the Securities at the time Outstanding of each series to be affected thereby on behalf of the Holders of all Securities of such series. The Indenture also permits
the Holders of a majority in aggregate principal amount of the Securities at the time Outstanding of each series, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture
and certain past defaults and their consequences with respect to such series under the Indenture. Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of
any Notes issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note or such other Notes. In addition, subject to certain exceptions set forth in
the Indenture, without the consent of any Holder, the Company and the Trustee may amend the Indenture or the Notes to make changes that do not adversely affect the rights of any Holder. 

No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company,
which is absolute and unconditional, to pay the principal of and interest on this Note at the place, rate and respective times and in the coin or currency herein and in the Indenture prescribed. 

  
 R-3 

 The Indenture contains provisions for defeasance at any time of (a) the entire indebtedness
of this Note and (b) certain restrictive covenants, upon compliance by the Company with certain conditions set forth therein. 
 The
Notes are issuable in fully registered form without coupons in denominations of $2,000 and any integral multiple of $1,000. Notes may be exchanged for a like aggregate principal amount of Notes of other authorized denominations at the office or
agency of the Company in the Borough of Manhattan, The City of New York, designated for such purpose and in the manner and subject to the limitations provided in the Indenture. 

The Trustee will be the Paying Agent and the Security Registrar with respect to the Notes. The Company reserves the right at any time to vary
or terminate the appointment of any Paying Agent or Security Registrar, to appoint additional or other Paying Agents and other Security Registrars, which may include the Company, and to approve any change in the office through which any Paying Agent
or Security Registrar acts; provided that there will at all times be a Paying Agent in The City of New York, that there will be no more than one Security Registrar for the Notes. 

Upon due presentment for registration of transfer of this Note at the office or agency of the Company in the Borough of Manhattan, The City
of New York, designated for such purpose, a new Note or Notes of authorized denominations for a like aggregate principal amount will be issued to the transferee in exchange therefor, subject to the limitations provided herein or in the Indenture.

 No charge shall be made for any such transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or
other governmental charge imposed in connection therewith. 
 The Company, the Trustee and any agent of the Company or the Trustee may
treat the Person in whose name this Note is registered as the owner hereof for all purposes, whether or not this Note is overdue, and none of the Company, the Trustee or any such agent shall be affected by notice to the contrary. 

Unless otherwise defined herein, all terms used in this Note that are defined in the Indenture shall have the meanings assigned to them in
the Indenture. 
 This Note shall be governed by and construed in accordance with the laws of the State of New York, without giving effect
to the conflict of laws provisions thereof.
