may direct). Such Global Notes, together with their Successor Notes which are Global Notes other than the Rule 144A Global Note, are collectively herein called the “Regulation S Global Note.” 
 Section 2.02. Execution and Authentication. 
 One Officer shall sign the Notes for the Company by manual or facsimile signature. 
 If an Officer whose
signature is on a Note no longer holds that office at the time a Note is authenticated, the Note shall nevertheless be valid. 
 A Note shall
not be valid until authenticated by the manual signature of the Trustee. The signature shall be conclusive evidence that the Note has been authenticated under this Indenture. 
 The Trustee shall, upon a written order of the Company signed by an Officer (an “Authentication Order”), authenticate Notes for original
issue on the Issue Date in an aggregate principal amount not to exceed $300 million (the “Original Notes”). Notes shall be dated the date of their authentication. 
 At any time and from time to time after the execution and delivery of this Indenture and after the effectiveness of a Registration Statement under the
Securities Act with respect thereto, the Company may deliver Exchange Notes executed by the Company to the Trustee for authentication, together with an Authentication Order for the authentication and delivery of such Exchange Notes and a like
principal amount of Original Notes for cancellation in accordance with Section 2.11 of this Indenture, and the Trustee in accordance with an Authentication Order shall authenticate and deliver such Notes. In authenticating such Exchange Notes,
and accepting the additional responsibilities under this Indenture in relation to such Notes, the Trustee shall be provided with, and (subject to Section 7.01) shall be fully protected in relying upon, an Opinion of Counsel stating, 

 

	 	(i)	that such Exchange Notes have been duly and validly issued in accordance with the terms of this Indenture, and are entitled to all the rights and benefits set forth herein; and

  

	 	(ii)	that the issuance of the Exchange Notes in exchange for the Original Notes has been effected in compliance with the Securities Act. 

 The Trustee may appoint an authenticating agent acceptable to the Company to authenticate Notes. An authenticating agent may authenticate Notes whenever
the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as an Agent to deal with Holders or an Affiliate of the Company.

 Section 2.03. Registrar and Paying Agent. 
 The Company shall maintain an office or agency where Notes may be presented for registration of transfer or for exchange (“Registrar”)
and an office or agency where Notes may be presented for payment (“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 promptly notify the Trustee in writing of the name and address of any Agent not a party to this Indenture. If the Company fails to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such. The
Company or any of its Subsidiaries may act as Paying Agent or Registrar. 
 The Company initially appoints The Depository Trust Company
(“DTC”) to act as Depositary with respect to the Global Notes. 
 The Company initially appoints the Trustee to act as the
Registrar and Paying Agent and to act as Custodian with respect to the Global Notes. 
 Section 2.04. Paying Agent to Hold Money in
Trust. 
 The Company shall require each Paying Agent other than the Trustee to agree in writing that the Paying Agent will 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 will 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 all 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 seven Business Days
before each Interest Payment Date and at such other times as the Trustee may reasonably 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 the Holders of Notes, and the
Company shall otherwise comply with TIA § 312(a). 
 Section 2.06. Transfer and Exchange. 
 (a) Transfer and Exchange of Global Notes. A Global Note may not be transferred as a whole except by the Depositary to a nominee of the
Depositary, by a nominee of the Depositary to the Depositary or to another nominee of the Depositary, or by the Depositary or 

  

 21 

 
any such nominee to a successor Depositary or a nominee of such successor Depositary. All Global Notes will be exchanged by the Company for Definitive Notes
if (i) the Company delivers to the Trustee notice from the Depositary that it is unwilling or unable to continue to act as Depositary or that it is no longer a clearing agency registered under the Exchange Act and, in either case, a successor
Depositary is not appointed by the Company within 120 days after the date of such notice from the Depositary, (ii) the Company in its sole discretion determines that the Global Notes (in whole but not in part) should be exchanged for Definitive
Notes and delivers a written notice to such effect to the Trustee, or (iii) an Event of Default has occurred and is continuing and the Registrar has received a request from the Depositary. Upon the occurrence of any of the preceding events in
(i), (ii) or (iii) above, Definitive Notes shall be issued in such names as the Depositary shall instruct the Trustee. The owner of a beneficial interest in a Global Note will be entitled to receive a Definitive Note in exchange for such
interest if an Event of Default has occurred and is continuing. Global Notes also may be exchanged or replaced, in whole or in part, as provided in Sections 2.07 and 2.10 hereof. Every Note authenticated and delivered in exchange for, or in lieu of,
a Global Note or any portion thereof, pursuant to this Section 2.06, or Section 2.07 or 2.10 hereof, shall be authenticated and delivered in the form of, and shall be, a Global Note. A Global Note may not be exchanged for another Note
other than as provided in this Section 2.06(a); provided, however, that beneficial interests in a Global Note may be transferred and exchanged as provided in Section 2.06(b), (c) or (f) hereof and a Global Note may be
exchanged for another Global Note as provided in Section 2.06(f) hereof. 
 In the event that Definitive Notes are not issued to each
holder of a beneficial interest in a Global Note promptly after the Registrar has received a request from the Holder of a Global Note to issue such Definitive Notes, the Company expressly acknowledges, with respect to the right of any Holder to
pursue a remedy pursuant to Section 6.06 or 6.07 hereof, the right of any beneficial holder of Notes to pursue such remedy with respect to the portion of the Global Note that represents such beneficial holder’s Notes as if such Definitive
Notes had been issued. 
 (b) Transfer and Exchange of Beneficial Interests in the Global Notes. The transfer and exchange of
beneficial interests in the Global Notes shall be effected through the Depositary, in accordance with the provisions of this Indenture and the Applicable Procedures. Transfers of beneficial interests in the Global Notes also shall require compliance
with either subparagraph (i) or (ii) below, as applicable, as well as one or more of the other following subparagraphs, as applicable: 
  

	 	(i)	Transfer of Beneficial Interests in the Same Global Note. Beneficial interests in any Global Note may be transferred to Persons who take delivery thereof in the form of a
beneficial interest in the same Global Note. No written orders or instructions shall be required to be delivered to the Registrar to effect the transfers described in this Section 2.06(b)(i). 

  

	 	(ii)	 All Other Transfers and Exchanges of Beneficial Interests in Global Notes. In connection with all transfers and exchanges of beneficial interests that are
not subject to Section 2.06(b)(i) above, the transferor of such beneficial interest must deliver to the Registrar either (A) (1) a written order from a Participant or an Indirect Participant given to the 

  

 22 

	 	 
Depositary in accordance with the Applicable Procedures directing the Depositary to credit or cause to be credited a beneficial interest in another Global
Note in an amount equal to the beneficial interest to be transferred or exchanged and (2) instructions given in accordance with the Applicable Procedures containing information regarding the Participant account to be credited with such increase
or (B) (1) a written order from a Participant or an Indirect Participant given to the Depositary in accordance with the Applicable Procedures directing the Depositary to cause to be issued a Definitive Note in an amount equal to the
beneficial interest to be transferred or exchanged and (2) instructions given by the Depositary to the Registrar containing information regarding the Person in whose name such Definitive Note shall be registered to effect the transfer or
exchange referred to in (1) above. Upon satisfaction of all of the requirements for transfer or exchange of beneficial interests in Global Notes contained in this Indenture and the Notes or otherwise applicable under the Securities Act, the
Trustee shall adjust the principal amount of the relevant Global Note(s) pursuant to Section 2.06(g) hereof. 

  

	 	(iii)	Rule 144A Global Note to Regulation S Global Note. If the owner of a beneficial interest in the Rule 144A Global Note wishes at any time to transfer such interest to a Person
who wishes to acquire the same in the form of a beneficial interest in the Regulation S Global Note, such transfer may be effected only in accordance with the provisions of this clause (iii) and clause (iv) below and subject to the
Applicable Procedures. Upon receipt by the Trustee, as Registrar, of (A) an order given by the Depositary or its authorized representative directing that a beneficial interest in the Regulation S Global Note in a specified principal amount be
credited to a specified Participant’s account and that a beneficial interest in the Rule 144A Global Note in an equal principal amount be debited from another specified Participant’s account and (B) a certificate in the form of
Exhibit B hereto, satisfactory to the Trustee and duly executed by the owner of such beneficial interest in the Rule 144A Global Note or his attorney duly authorized in writing, then the Trustee, as Registrar but subject to clause (iv) below,

	 	(iv)	 Regulation S Global Note to Rule 144A Global Note. If the owner of a beneficial interest in the Regulation S Global Note wishes at any time to transfer such
interest to a Person who wishes to acquire the same in the form of a beneficial interest in the Rule 144A Global Note, such transfer may be effected only in accordance with this clause (iv) and subject to the Applicable Procedures. Upon receipt
by the Trustee, as Registrar, of (A) an order given by the Depositary or its authorized representative directing that a beneficial interest in the Rule 144A Global Note in a specified principal amount be credited to a specified
Participant’s account and that a 

  

 23 

	 	 
beneficial interest in the Regulation S Global Note in an equal principal amount be debited from another specified Participant’s account and (B) if
such transfer is to occur during the Restricted Period, a certificate in the form of Exhibit C hereto, satisfactory to the Trustee and duly executed by the owner of such beneficial interest in the Regulation S Global Note or his attorney duly
authorized in writing, then the Trustee, as Registrar, shall reduce the principal amount of the Regulation S Global Note and increase the principal amount of the Rule 144A Global Note by such specified principal amount. 

(c) Transfer or Exchange of Beneficial Interests for Definitive Notes. If any Holder of a beneficial interest in a Global Note proposes to
exchange such beneficial interest for a Definitive Note or to transfer such beneficial interest to a Person who takes delivery thereof in the form of a Definitive Note, then, upon satisfaction of the conditions set forth in Sections 2.06(a) and
2.06(b)(ii) hereof, the Trustee shall cause the aggregate principal amount of the applicable Global Note to be reduced accordingly pursuant to Section 2.06(g) hereof, and the Company shall execute and the Trustee shall authenticate and deliver
to the Person designated in the instructions a Definitive Note in the appropriate principal amount. Any Definitive Note issued in exchange for a beneficial interest pursuant to this Section 2.06(c) shall bear the legend restricting transfers
that is borne by such Global Note and shall be registered in such name or names and in such authorized denomination or denominations as the holder of such beneficial interest shall instruct the Registrar through instructions from the Depositary and
the Participant or Indirect Participant. 
 (d) Transfer or Exchange of Definitive Notes for Beneficial Interests. Upon request by a
Holder of Definitive Notes to exchange such Definitive Notes for a beneficial interest in a Global Note and such requesting Holder’s presenting or surrendering to the Registrar the Definitive Notes duly endorsed or accompanied by a written
instruction of transfer in form satisfactory to the Registrar duly executed by such Holder or by its attorney, duly authorized in writing, the Registrar shall register the transfer or exchange of Definitive Notes and effect the transfer or exchange
through the Depositary, in accordance with the provisions of this Indenture and the Applicable Procedures. The Trustee shall cancel the Definitive Note and cause the aggregate principal amount of the applicable Global Note to be increased
accordingly pursuant to the terms of this Indenture and the Applicable Procedures. If the Definitive Note to be transferred in whole or in part is a Restricted Note, or is a Regulation S Note and the transfer is to occur during the Restricted Period
therefor, then the Trustee shall have received (A) a certificate substantially in the form of Exhibit C hereto, satisfactory to the Trustee and duly executed by the transferor Holder or his attorney duly authorized in writing, in which case the
transferee Holder shall take delivery in the form of a beneficial interest in the Restricted Global Note, or (B) a certificate substantially in the form of Exhibit B hereto, satisfactory to the Trustee and duly executed by the transferor Holder
or his attorney duly authorized in writing, in which case the transferee Holder shall take delivery in the form of a beneficial interest in the Regulation S Global Note (subject in every case to Section 2.06(f)). 
 (e) Transfer and Exchange of Definitive Notes for Definitive Notes. Upon request by a Holder of Definitive Notes and such requesting Holder’s
presenting or surrendering to the Registrar the Definitive Notes duly endorsed or accompanied by a written instruction of transfer 

  

 24 

 
in form satisfactory to the Registrar duly executed by such Holder or by its attorney, duly authorized in writing, the Registrar shall register the transfer
or exchange of Definitive Notes; provided that, if the Note to be transferred in whole or in part is a Restricted Note, or is a Regulation S Note and the transfer is to occur during the Restricted Period therefor, then the Trustee shall have

Sections 2.10, 3.07, 4.09 and 9.06 hereof). 

  

	 	(iii)	The Registrar shall not be required to register the transfer of or exchange any Note selected for redemption in whole or in part, except the unredeemed portion of any Note being
redeemed in part. 

  

	 	(iv)	All Global Notes and Definitive Notes issued upon any registration of transfer or exchange of Global Notes or Definitive Notes shall be the valid obligations of the Company,
evidencing the same debt, and entitled to the same benefits under this Indenture, as the Global Notes or Definitive Notes surrendered upon such registration of transfer or exchange. 

  

	 	(v)	The Company shall not be required (A) to issue, to register the transfer of or to exchange any Notes during a period beginning at the opening of business 15 days before the
date of any selection of Notes for redemption under Section 3.02 hereof and ending at the close of business on the day of selection, (B) to register the transfer of or to exchange any Note (i) selected for redemption in whole or in

Regular Record Date and ending at the close of business on such Regular Record Date. 

  

	 	(vi)	Prior to due presentment for the registration of a transfer of any Note, the Trustee, any Agent and the Company may deem and treat the Person in whose name any Note is registered as
the absolute owner of such Note for the purpose of receiving payment of principal of and premium, if any, and interest on such Notes and for all other purposes, and none of the Trustee, any Agent or the Company shall be affected by notice to the

 29 

	 	(viii)	All certifications, certificates and Opinions of Counsel required to be submitted to the Registrar pursuant to this Section 2.06 to effect a registration of transfer or
exchange may be submitted by facsimile. 

  

	 	(i)	Applicable Procedures for Delegending. 

  

	 	(i)	Promptly after one year has elapsed following (A) the date of original issuance of the Notes or (B) if the Company has issued any Additional Notes with the same terms and
the same CUSIP number as the Notes pursuant to Section 2.14 hereof within one year following the date of original issuance of the Notes, the date of original issuance of such Additional Notes, if the Notes are freely tradeable pursuant to Rule
144 under the Securities Act by Holders who are not Affiliates of the Company where no conditions of Rule 144 are then applicable (other than the holding period requirement in paragraph (d)(1)(ii) of Rule 144 so long as such holding period
requirement is satisfied), the Company shall: 

  

	 	(1)	instruct the Trustee in writing to remove the Restricted Notes Legend from the Notes by delivering to the Trustee a certificate in the form of Exhibit D hereto, and upon such
instruction the Restricted Notes Legend shall be deemed removed from any Global Notes representing such Notes without further action on the part of Holders;

	 	(3)	instruct DTC to change the CUSIP number for the Notes to the unrestricted CUSIP number for the Notes. 

 In no event will the failure of the Company to provide any notice set forth in this paragraph or of the Trustee to remove the Restricted Notes Legend
constitute a failure by the Company to comply with any of its covenants or agreements set forth in Section 6.01 or otherwise. Any Restricted Note (or security issued in exchange or substitution therefor) as to which such restrictions on
transfer shall have expired in accordance with their terms may, upon surrender of such Restricted Note for exchange to the Registrar in accordance with the provisions of Article Two of the Indenture, be exchanged for a new Note or Notes, of like
tenor and aggregate principal amount, which shall not bear the Restricted Notes Legend. The Issuer shall notify the Trustee in writing upon the occurrence of the Resale Restriction Termination Date and promptly after a registration statement with
respect to the Notes, if any, has been declared effective under the Securities Act. 
  

	 	(ii)	 Notwithstanding any provision of this Sections 2.06 to the contrary, in the event that Rule 144 as promulgated under the Securities Act (or any successor rule) is
amended to change the one-year holding period 

  

 30 

	 	 
thereunder (or the corresponding period under any successor rule), (i) each reference in this Section 2.06(i) to “one year” and in the
Restricted Notes Legend and in Section 2.06(f)(i)(A) herein to “ONE YEAR” shall be deemed for all purposes hereof to be references to such changed period, and (ii) all corresponding references in the Notes (including the
definition of Resale Restriction Termination Date) and the Restricted Notes Legends thereon shall be deemed for all purposes hereof to be references to such changed period, provided, that such changes shall not become effective if they are
otherwise prohibited by, or would otherwise cause a violation of, the then-applicable federal securities laws. This Section 2.06(i)(ii) shall apply to successive amendments to Rule 144 (or any successor rule) changing the holding period
thereunder. 

 Section 2.07. Replacement Notes. 
 If any mutilated Note is surrendered to the Trustee or the Company and the Trustee receives evidence to its satisfaction of the destruction, loss or
theft of any Note, the Company shall issue and the Trustee, upon receipt of an Authentication Order, shall authenticate a replacement Note if the Trustee’s requirements are met. If required by the Trustee or the Company, an indemnity bond must
be supplied by the Holder that is sufficient in the judgment of the Trustee and the Company to protect the Company, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Company may
charge for its expenses in replacing a Note. 
 Every replacement Note is an additional obligation of the Company and shall be entitled to
all of the benefits of this Indenture equally and proportionately with all other Notes duly issued hereunder. 
 Section 2.08.
Outstanding Notes. 
 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 as not outstanding. Except as set forth in
Section 2.09 hereof, a Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note. 
 If a
Note is replaced pursuant to Section 2.07 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. 
 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.

 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 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.

 Section 2.09. 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 Person directly or indirectly controlling or controlled by or under direct or indirect common control with 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 knows are so owned shall be so disregarded. 
 Section 2.10. Temporary Notes. 
 Until certificates representing Notes are ready for delivery, the Company may prepare
and the Trustee, upon receipt of an Authentication 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 shall authenticate definitive Notes in exchange for temporary Notes. 
 Holders of temporary Notes shall be entitled to all of the benefits of this Indenture. 
 Section 2.11. Cancellation. 
 The Company at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee and no one
else shall cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and shall dispose of such cancelled Notes in its customary manner in accordance with prudent business practices. The Company may not
issue new Notes to replace Notes that it has paid or that have been delivered to the Trustee for cancellation except as expressly permitted pursuant to this Indenture. 
 Section 2.12. Defaulted Interest. 
 If the Company defaults in a payment of interest on the
Notes, it shall pay the defaulted interest in any lawful manner, plus, to the extent lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, in each case at the rate provided in the
Notes and in Section 4.01 hereof. The Company shall notify the Trustee in writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment. The Company shall fix or cause to be fixed each such
special record date and payment date, provided that no such special record date shall be less than 10 days prior to the related payment date for such defaulted interest. At least 15 days before the special record date, the Company (or, upon
the written request of the Company and provision of the notice information to the Trustee, the Trustee in the name and at the expense of the Company) shall mail or cause to be mailed to Holders a notice that states the special record date, the
related payment date and the amount of such interest to be paid. 
  

 32 

 Section 2.13. CUSIP or ISIN Numbers. 
 The Trustee shall use “CUSIP” and/or “ISIN” numbers in notices of redemption as a convenience to Holders if the Company uses
“CUSIP” and/or “ISIN” numbers in issuing the Notes; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice
of a redemption and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company will promptly notify the Trustee
of any change in the “CUSIP” and/or “ISIN” numbers. 
 Section 2.14. Additional Notes. 
 The Company may, from time to time, subject to compliance with any other applicable provisions of this Indenture, without the consent of the Holders,
create and issue pursuant to this Indenture additional notes (“Additional Notes”) having terms and conditions identical to those of the Notes, except that Additional Notes: 
 (i) may have a different issue date from the Notes; 
 (ii) may have a different amount of interest payable on the first Interest Payment Date after issuance than is payable on other Notes; and 
 (iii) may have terms specified in the Additional Note Board Resolution or Additional Note Supplemental Indenture for such Additional Notes making appropriate adjustments to this Article II and Exhibit A (and related definitions) applicable
to such Additional Notes in order to conform to and ensure compliance with the Securities Act (or other applicable securities laws) and any registration rights or similar agreement applicable to such Additional Notes, which are not adverse in any
material respect to the Holder of any Notes (other than such Additional Notes); 
 provided, that no adjustment pursuant to this Section 2.14
shall cause such Additional Notes to constitute, as determined pursuant to an Opinion of Counsel, a different class of securities than the Original Notes for U.S. federal income tax purposes except for Additional Notes that have a separate CUSIP
and/or ISIN number from the Notes pending performance by the Company of its obligations under the Registration Rights Agreement.

or in such other manner as the Trustee deems fair and appropriate.

 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 45 days (or such shorter time as may be agreed to by the Trustee) prior to the redemption date, an Officers’ Certificate requesting that

the Notes or the portions of the Notes called for redemption shall cease to accrue for as long as the Company has deposited with the Trustee or Paying Agent funds in satisfaction of the applicable redemption price. If a Note is redeemed on or after
a Regular Record Date but on or prior to the related Interest Payment Date, then any accrued and unpaid interest and Additional Interest, if any, shall be paid to the Person in whose name such Note was registered at the close of business on such
Regular Record Date. 
 Section 3.06. Notes Redeemed in Part. 
 Upon surrender of a Note that is redeemed in part, the Company shall issue and, upon the Company’s written request, the Trustee shall authenticate
for the Holder at the expense of the Company a new Note equal in principal amount to the unredeemed portion of the Note surrendered. If a Global Note is so surrendered, such new Note shall also be a Global Note.

	 	(2)	as determined by an Independent Investment Banker, the sum of the present values of the remaining scheduled payments of interest on the notes to be redeemed (not including any

any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and
demands may be made or served at the Corporate Trust Office. 
 The Company may also from time to time designate one or more other offices or
agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the
Company of its obligation to maintain an office or agency in the Borough of Manhattan, The City of New York, for such purposes. The Company shall give prompt written notice to the Trustee of any such designation or rescission and of any change in
the location of any such other office or agency.

Holders by rules and regulations prescribed from time to time by the SEC. 
 Delivery of such reports, information and documents to the
Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s
compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates). 
 Section 4.04. Compliance Certificate.

performance or observance of any of the terms, provisions and conditions of this Indenture (or, if a Default or Event of Default shall have occurred, describing all such Defaults or Events of Default of which he or she may have knowledge and what
action the Company is taking or proposes to take with respect thereto).

shall cause each of its Subsidiaries to pay or discharge, prior to delinquency, all material taxes, assessments, and governmental levies except such as are contested in good faith and by appropriate proceedings or where the failure to effect such
payment is not adverse in any material respect to the Holders of the Notes. 
  

 38 

 Section 4.06. Stay, Extension and Usury Laws. 
 The Company covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or
take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do
so) hereby expressly waives all benefit or advantage of any such law, and covenants that it shall not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the
execution of every such power as though no such law has been enacted. 
 Section 4.07. Limitation on Subsidiary Indebtedness.

 The Company shall not permit any of its Subsidiaries, directly or indirectly, to create, incur, issue, assume, guarantee or otherwise
become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “incur”) any Indebtedness, other than: 
  

	 	(1)	Indebtedness in an aggregate principal amount (without duplication) incurred pursuant to this clause (1) and outstanding, when taken together with the aggregate principal
amount of outstanding Indebtedness secured by Liens on the property or assets (which includes Capital Stock) of the Company and its Subsidiaries incurred pursuant to the second paragraph of Section 4.08, not to exceed the Permitted Amount at
the time of incurrence of such Indebtedness (it being understood that Existing SpectraSite Indebtedness shall be deemed to be incurred under this clause (1)); 

  

	 	(2)	Indebtedness of any Designated Subsidiary or any Subsidiary of such Designated Subsidiary; provided that, with respect to this clause (2) only, no portion of such
Indebtedness shall be recourse to the Company or any of its other Subsidiaries; 

  

	 	(3)	Indebtedness since the Issue Date 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 any business of the Company or any Subsidiary of the Company in an aggregate principal amount, including all Indebtedness incurred to
refund, refinance or replace any other Indebtedness incurred pursuant to this clause (3), not to exceed $500.0 million at any time outstanding; 

  

	 	(4)	intercompany Indebtedness between or among the Company and any of its Subsidiaries;

	 	(7)	Indebtedness represented by letters of credit, for the account of such Person, in the ordinary course of business to the extent such letters of credit are not drawn upon or, if
drawn upon, are reimbursed within five Business Days of the relevant draw; 

  

	 	(8)	Indebtedness arising from the honoring by a bank or other financial institution of a check, draft or similar instrument inadvertently (except in the case of daylight overdrafts)
drawn against insufficient funds in the ordinary course of business; provided, that such Indebtedness is extinguished within five business days of incurrence; 

  

	 	(9)	Acquired Indebtedness in connection with a merger with or into a Subsidiary, or the acquisition of assets or a new Subsidiary; provided that, in the case of any such
incurrence of Acquired Indebtedness, such Acquired Indebtedness was incurred by the prior owner of such assets or such Subsidiary prior to such acquisition by the Company or one of its Subsidiaries and was not incurred in connection with, or in
contemplation of, the acquisition by the Company or one of its Subsidiaries; 

  

	 	(10)	Disqualified Stock since the Issue Date in an aggregate principal amount (or liquidation preference, as applicable) at any time outstanding not to exceed $100.0 million;

  

	 	(11)	Indebtedness (other than Existing SpectraSite Indebtedness) existing on the Issue Date; or 

  

	 	(12)	Indebtedness of any Subsidiary of the Company issued in exchange for, or the net proceeds of which are used or will be used to extend, refinance, renew, replace, defease or refund
(including through open market purchases and tender offers), other Indebtedness that was permitted by the applicable indenture to be incurred under clauses (9) or (11) or this clause (12) of this paragraph. 

The maximum amount of Indebtedness that may be incurred pursuant to this Section 4.07 will not be deemed to be exceeded with respect to any
outstanding Indebtedness due solely to the result of fluctuations in the exchange rates of currencies. In addition, the accrual of interest, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the
form of additional Indebtedness with the same terms, and the payment of dividends on Disqualified Stock in the form of additional shares of the same class of Disqualified Stock shall not be deemed to be an incurrence of Indebtedness for purposes of
this Section 4.07. For purposes of determining compliance with this Section 4.07, in the event that an item of proposed Indebtedness meets the criteria of more than one of the categories of Indebtedness described in clauses
(1) through (12) above, the Company will be permitted to classify, or later reclassify, all or a portion of such item of Indebtedness in any manner that complies with this Section 4.07. 
  

 40 

 Section 4.08. Limitation on Liens. 
 The Company shall not, and shall not permit any of its Subsidiaries to, allow any Lien on any of the Company’s or its Subsidiaries’ property or
assets (which includes Capital Stock) securing Indebtedness, unless the Lien secures the Notes equally and ratably with, or prior to, any other Indebtedness secured by such Lien, so long as such other Indebtedness is so secured, other than Permitted
Liens. 
 Notwithstanding the foregoing, the Company may, and may permit any of its Subsidiaries to, incur Liens securing Indebtedness
without equally and ratably securing the Notes if, after giving effect to the incurrence of such Liens, the aggregate amount (without duplication) of (a) the Indebtedness secured by Liens (other than Permitted Liens) on the property or assets
(which includes Capital Stock) of the Company and its Subsidiaries plus (b) the Indebtedness of the Company’s Subsidiaries incurred pursuant to clause (1) of the first paragraph of Section 4.07 and outstanding shall not
exceed the Permitted Amount at the time of the incurrence of such Liens (it being understood that Liens securing Existing SpectraSite Indebtedness shall be deemed to be incurred pursuant to this paragraph). 
 Section 4.09. Repurchase of the Notes Upon a Change of Control Triggering Event. 
 Upon the occurrence of a Change of Control Triggering Event, each Holder of Notes shall have the right to require the Company to repurchase all or any
part, equal to $2,000 or an integral multiple of $1,000 thereafter, of that Holder’s Notes pursuant to an offer (the “Change of Control Offer”) on the terms set forth in this Indenture at an offer price in cash equal to 101% of
the aggregate principal amount of Notes repurchased plus accrued and unpaid interest on the Notes up to but excluding the applicable date of repurchase (the “Change of Control Payment”). Within 30 days following any Change of
Control Triggering Event, if the Company had not, prior to the Change of Control Triggering Event, sent a redemption notice for all the Notes in connection with an optional redemption permitted by Section 3.07 hereof, the Company shall mail or
caused to be mailed a notice to each registered Holder briefly describing the transaction or transactions that constitute a Change of Control Triggering Event and offering to repurchase Notes on the date specified in such notice (the “Change
of Control Payment Date”), which date shall be no earlier than 30 days and no later than 60 days from the date the notice is mailed, pursuant to the procedures required by this Indenture and described in such notice. 
 The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable to any Change of Control Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 4.09, the Company shall comply with the
applicable securities laws and regulations and will not be deemed to have breached its obligations under the provisions of this Section 4.09 by virtue of such conflict. 
 On the Change of Control Payment Date, the Company shall, to the extent lawful: 
 (a) accept for payment all Notes or portions thereof properly tendered pursuant to the Change of Control Offer; 
  

 41 

 (b) deposit with the Paying Agent an amount equal to the Change of Control Payment in
respect of all Notes or portions thereof properly tendered; and 
 (c) 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 thereof being purchased by the Company. 
 The Paying Agent will promptly mail to each registered Holder of Notes so tendered the Change of Control Payment for such Notes, and the Trustee will promptly authenticate and mail (at the Company’s expense), or
cause to be transferred by book entry, to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided that each such new Note shall be in a principal amount of $2,000 or an integral
multiple of $1,000 thereafter. Any Note so accepted for payment shall cease to accrue interest on and after the Change of Control Payment Date. 
 This Section 4.09 shall be applicable, except as described in this Section 4.09, regardless of whether or not any other provisions of this Indenture are applicable. 
 Notwithstanding the foregoing, the Company shall not be required to make a Change of Control Offer upon a Change of Control Triggering Event if a third
party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 4.09 applicable to a Change of Control Offer made by the Company and purchases all Notes properly
tendered and not withdrawn under the Change of Control Offer. 
 The Company may make a Change of Control Offer in advance of a Change of
Control Triggering Event, and conditional upon the occurrence of such Change of Control Triggering Event, if a definitive agreement is in place for the Change of Control Triggering Event at the time of making the Change of Control Offer. 

Section 4.10. Termination of Covenant. 
 In the event that the Notes receive an Investment Grade Rating from at least two of the three Rating Agencies, and notwithstanding that the Notes may later cease to have an Investment Grade Rating from any Rating
Agency, the Company and its Subsidiaries shall be released from their obligations to comply with Section 4.07 and those obligations will not at any future point be reinstated.

 The Company may not consolidate or merge with or into, or sell, lease or convey all or substantially all of its assets in any one transaction or series of related transactions to any other Person, unless:

in the case of a lease of all or substantially all of the Company’s assets), the successor corporation formed by such consolidation or into or with which the Company is merged or to which such sale, assignment, transfer, lease, conveyance or
other disposition is made shall succeed to, and be substituted for (so that from and after the date of such consolidation, merger, sale, lease, conveyance or other disposition, the provisions of this Indenture referring to the “Company”
shall refer instead to the successor corporation and not to the Company), and may exercise every right and power of the Company under this Indenture with the same effect as if such successor Person had been named as the Company herein;
provided, however, that the predecessor Company shall not be relieved from the obligation to pay the principal of and interest on the Notes except in the case of a sale of all of the Company’s assets that meets the requirements of
Section 5.01 hereof. 
 ARTICLE 6 
 DEFAULTS AND REMEDIES 
 Section 6.01. Events of Default. 
 The term “Event of Default” with respect to the Notes, wherever used herein, means any one of the following events which shall have
occurred and be continuing (whatever the reason for such Event of Default), whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of
any administrative or governmental body): 
  

	 	(1)	failure by the Company to pay interest on any Note for 30 days after the date payment is due and payable; or

of its Significant Subsidiaries or the payment of which is Guaranteed by the Company or any of its Significant Subsidiaries, other than Indebtedness owed to the Company or a Subsidiary, whether such Indebtedness or Guarantee now exists or is created
after the Issue Date, if both: 

  

	 	(a)	such default either results from the failure to pay any principal of such Indebtedness at its stated final maturity (after giving effect to any applicable grace periods) or relates
to an obligation other than the obligation to pay principal of any such Indebtedness at its stated final maturity and results in the holder or holders of such Indebtedness causing such Indebtedness to become due prior to its stated maturity; and

  

	 	(b)	the principal amount of such Indebtedness, together with the principal amount of any other such Indebtedness in default for failure to pay principal at stated final maturity (after
giving effect to any applicable grace periods), or the maturity of which has been so accelerated, aggregate $100.0 million or more at any time outstanding; 

 provided, that, in the case of this clause (4), it shall not be an Event of Default if any such default arises in connection with the Indebtedness of any Subsidiary of the Company that is designated as an
“Unrestricted Subsidiary” under any indenture governing the Outstanding Notes; or 
  

	 	(5)	the Company or any of its Significant Subsidiaries pursuant to or within the meaning of Bankruptcy Law: 

  

	 	(a)	commences a voluntary case, 

  

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

  

	 	(c)	consents to the appointment of a custodian of it or for all or substantially all of its property, 

  

	 	(d)	makes a general assignment for the benefit of its creditors, or 

  

	 	(e)	generally is not paying its debts as they become due; or 

  

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

  

	 	(a)	is for relief against the Company or any of its Significant Subsidiaries in an involuntary case; 

  

 44 

	 	(b)	appoints a custodian of the Company or any of its Significant Subsidiaries or for all or substantially all of the property of the Company or any of its Significant Subsidiaries; or

  

	 	(c)	orders the liquidation of the Company or any of its Significant Subsidiaries; 

 and the order or decree remains unstayed and in effect for 60 consecutive days. 
 Section 6.02.
Acceleration. 
 If an Event of Default described in clauses (1) through (4) of Section 6.01 hereof occurs and is
continuing, then, and in each and every such case, either the Trustee or the Holders of not less than 25% in aggregate principal amount of the Notes then outstanding hereunder by notice in writing to the Company (and to the Trustee if given by
Holders), may declare the entire principal of all Notes, and the interest and Additional Interest accrued thereon, if any, to be due and payable immediately, and upon any such declaration, the same shall become immediately due and payable.

 If an Event of Default described in clause (5) or (6) of Section 6.01 hereof occurs and is continuing, then the principal
amount of all the Notes then outstanding, and the interest and Additional Interest accrued thereon, if any, shall become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. 
 Section 6.03. Other Remedies. 
 If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal amount of, premium, if any, and interest on the Notes or to enforce the performance of any provision of the
Notes or this Indenture. 
 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 a Note 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. 
 Notwithstanding the foregoing, the sole remedy for any breach of the
Company’s obligation under this Indenture to file or furnish reports or other financial information pursuant to section 314(a)(1) of the Trust Indenture Act (or as otherwise required by this Indenture) shall be the payment of liquidated
damages, and the Holders will not have any right under this Indenture to accelerate the maturity of the Notes as a result of any such breach. If any such breach continues for 90 days after notice thereof is given in accordance with this Indentures,
we will pay liquidated damages to all the Holders of the Notes at a rate per annum equal to (i) 0.25% per annum of the principal amount of the Notes from the 90th day following such notice to but not including the 180th day following such
notice (or such earlier date on which the Event of Default relating to the reporting obligations referred to in this paragraph shall have been cured or waived) and (ii) 0.50% per annum of the principal amount of the Notes from the 180th day

  

 45 

 
following such notice to but not including the 365th day following such notice (or such earlier date on which the Event of Default relating to the reporting
obligations referred to in this paragraph shall have been cured or waived). On such 365th day (or earlier, if the Event of Default relating to the reporting obligations referred to in this paragraph shall have been cured or waived prior to such
365th day), such additional interest will cease to accrue, and the Notes will be subject to acceleration as provided above if the Event of Default is continuing. This paragraph will not affect the rights of the holders of Notes in the event of the
occurrence of any other Event of Default. 
 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 amount, premium, if any, and any accrued and unpaid 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 this 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 this 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. 
 Section 6.06.
Limitation on Suits. 
 A Holder of a Note may pursue a remedy with respect to this Indenture or the Notes only if: 
  

	 	(1)	the Holder of a Note gives to the Trustee written notice of an Event of Default and the continuance of such Event of Default; 

  

	 	(2)	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; 

  

	 	(3)	the Trustee does not comply with the request within 60 days after receipt of the request; and 

  

 46 

	 	(4)	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.

 A Holder of a Note may not use this Indenture to prejudice the rights of another Holder of a Note or to obtain a preference
or priority over another Holder of a Note. 
 Section 6.07. Rights of Holders of Notes to Receive Payment. 
 Notwithstanding any other provision of this 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 clauses (1) or (2) of Section 6.01 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 of the Notes 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. 
  

 47 

 Section 6.10. Priorities. 
 If the Trustee collects any money pursuant to this Article, 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 of Notes 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. 
 The Trustee may fix a record date and payment date for any payment to Holders of Notes pursuant to this Section 6.10. 
 Section 6.11. Undertaking for Costs. 
 In any suit for the enforcement of any right or remedy under this 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 does not apply to a suit by the Trustee, a suit by a Holder of a Note pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in principal amount of
the then outstanding Notes.

 The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Company or any Affiliate of
the Company with the same 

  

 50 

 
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 Sections 7.10 and 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 this Indenture or the Notes, it shall not be accountable for the Company’s use of the proceeds from the Notes

 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 mail to Holders of Notes a notice of the Default or Event of Default within 90 days after it
occurs. Except with respect to a Default or Event of Default relating to the payment of principal of, premium, if any, or interest on the Notes, 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 the Holders of the Notes.

Holders of the Notes. 
 Within 60 days after each December 15 beginning with the December 15 following the Issue Date, and for

except to the extent any such loss, liability or expense is caused by its own negligence, bad faith or willful misconduct. The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so
notify the Company shall not relieve the Company of its obligations hereunder. The Company shall defend the claim and the Trustee shall cooperate in the defense. The Trustee may have separate counsel and the Company shall pay the reasonable fees and
expenses of such counsel. The Company need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld. 
 The obligations of the Company under this Section 7.07 shall survive the satisfaction and discharge of this Indenture and the resignation or removal of the Trustee.

	 	(b)	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; 

  

	 	(c)	a custodian or public officer takes charge of the Trustee or its property; or 

  

	 	(d)	the Trustee becomes incapable of acting. 

 If the Trustee
resigns or is removed or if a vacancy exists in the office of Trustee for any reason, 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. 
 If a successor
Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company, or the Holders of at least 10% in principal amount of the then outstanding Notes may petition at the expense of the
Company any court of competent jurisdiction for the appointment of a successor Trustee.

 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 this Indenture. The successor Trustee shall mail a notice of its succession to Holders. The retiring
Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, provided all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in Section 7.07 hereof.

successor Trustee.

any state thereof that is authorized under such laws to exercise corporate trustee power, that is subject to supervision or examination by federal or state authorities and that has a combined capital and surplus of at least $75.0 million as set

from the Company. 
 Any application by the Trustee for written instructions from the Company may, at the option of the Trustee, set
forth in writing any action proposed to be taken or omitted by the Trustee under this Indenture and the date on and/or after which such action shall be taken or such omission shall be effective. The Trustee shall not be liable for any action taken
by, or omission of, the Trustee in accordance with a proposal included in such application on or after the date specified in such application (which date shall not be less than three Business Days after the date any Officer of the Company actually
receives such application, unless any such Officer shall have consented in writing to any earlier date) unless prior to taking any such action (or the effective date in the case of an omission), the Trustee shall have received written instructions
in response to such application specifying the action to be taken or omitted. 
 ARTICLE 8 
 LEGAL DEFEASANCE AND COVENANT DEFEASANCE 
 Section 8.01. Option to Effect Legal Defeasance or Covenant Defeasance.

Article 8. 
 Section 8.02. Legal Defeasance and Discharge. 
 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 this Indenture referred to in (1) and (2) below, and to have satisfied all its other obligations under such Notes and this Indenture (and the Trustee, on demand of
and at the expense of the Company, shall execute proper instruments provided to it acknowledging the same), except for the following provisions which shall survive until otherwise terminated or discharged hereunder: 
  

	 	(1)	the rights of Holders of outstanding Notes to receive payments in respect of the principal amount, premium, if any, interest and Additional Interest, if any, on such Notes when such
payments are due from the trust referred to in Section 8.04 hereof; 

  

 54

 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 4.07, 4.08
and 4.09 hereof and Section 5.01 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 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 this 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, Sections 6.01(5) and 6.01(6) hereof shall not constitute Events of Default.

either Section 8.02 or 8.03 hereof to the outstanding Notes:

 55 

	 	 
firm of independent public accountants, to pay the principal of, premium, if any, interest and Additional Interest, if any, on the outstanding Notes on the
stated date for payment thereof or on the applicable redemption date, as the case may be, and the Company shall specify whether the Notes are being defeased to maturity or to a particular redemption date;

	 	(a)	the Company has received from, or there has been published by, the Internal Revenue Service a ruling; or 

  

	 	(b)	since the Issue Date, 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 will confirm
that, the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will 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; 

  

	 	(3)	in the case of an election under Section 8.03 hereof, the Company has delivered to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that the
Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will 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; 

  

	 	(4)	no Default or Event of Default has occurred and is continuing 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);

	 	(6)	the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that on the 91st day following the deposit, the trust funds will not be subject to the effect of

	 	(7)	 the Company shall have delivered to the Trustee an Officers’ Certificate stating that the deposit was not made by the Company with the intent of 

  

 56 

	 	 
preferring the Holders over any other creditors of the Company or with the intent of defeating, hindering, delaying or defrauding any other creditors of the
Company or others; and 

  

	 	(8)	the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for or 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. 
 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 this 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.

 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. 
 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 

  

 57 

 
once, in The New York Times and The Wall Street 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 will 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 this 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. Supplemental Indentures without Consent of
Holders of Notes. 
 The Company, when authorized by a Board Resolution (which resolution may provide general terms or parameters for
such action and may provide that the specific terms of such action may be determined in accordance with or pursuant to an Officers’ Certificate), and the Trustee may from time to time and at any time enter into an indenture or indentures
supplemental hereto (which shall conform to the provisions of the TIA as in force at the date of the execution thereof) for one or more of the following purposes: 
  

	 	(1)	to convey, transfer, assign, mortgage or pledge to the Trustee as security for the Notes any property or assets; 

  

	 	(2)	to evidence the assumption of the Company’s obligations to Holders of Notes in the case of a merger, amalgamation or consolidation of the Company or sale of all or
substantially all of the assets of the Company; 

  

	 	(3)	 to add to the covenants of the Company such further covenants, restrictions, conditions or provisions as the Company and the Trustee shall consider to be for the
protection of the Holders of the Notes, and to make the occurrence, or the occurrence and continuance, of a default in any such additional covenants, restrictions, conditions or provisions an Event of Default permitting the enforcement of all or any
of the several remedies provided in this Indenture as herein set forth; provided, however, that in respect of any such additional covenant, restriction, condition or provision 

  

 58 

	 	 
such supplemental indenture may provide for a particular period of grace after default (which period may be shorter or longer than that allowed in the case
of other defaults) or may provide for an immediate enforcement upon such an Event of Default or may limit the remedies available to the Trustee upon such an Event of Default or may limit the right of the Holders of a majority in aggregate principal
amount of the Notes to waive such an Event of Default; 

  

	 	(4)	to cure any ambiguity or to correct or supplement any provision contained herein or in any supplemental indenture that may be defective or inconsistent with any other provision
contained herein or in any supplemental indenture, or to make any other provisions as the Company may deem necessary or desirable; provided, however, that no such provisions shall materially adversely affect the interests of the Holders of
the Notes; 

  

	 	(5)	to evidence and provide for the acceptance of the appointment of a successor Trustee pursuant to Section 7.08 hereof; 

  

	 	(6)	to provide for uncertificated Notes in addition to or in place of certificated Notes or to alter the provisions of Article 2 hereof (including the related definitions) in a manner
that does not materially adversely affect any Holder; 

  

	 	(7)	to conform the text of this Indenture or the Notes to any provision of the “Description of the Notes” in the Offering Circular to the extent that such provision in the
“Description of the Notes” was intended to be a verbatim recitation of a provision of this Indenture or the Notes; 

  

	 	(8)	to provide for the issuance of Additional Notes as permitted by Sections 2.14, which will have terms substantially identical to the other Notes except as specified in
Section 2.14, and which will be treated, together with any other Notes, as a single issue of securities; 

  

	 	(9)	to make any change that would provide any additional rights or benefits to the Holders of the Notes or that does not adversely affect the legal rights hereunder of any Holder of
Notes or any holder of a beneficial interest in the Notes; or 

  

	 	(10)	to comply with requirements of the SEC in order to effect or maintain the qualification of this Indenture under the TIA. 

 Upon the request of the Company accompanied by a resolution of its Board of Directors 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 this
Indenture. The Trustee is hereby authorized to join with the 

  

 59 

 
Company in the execution of any such supplemental indenture, to make any further appropriate agreements and stipulations which may be therein contained and
to accept the conveyance, transfer, assignment, mortgage or pledge of any property thereunder, but the Trustee shall not be obligated to enter into any such supplemental indenture which affects the Trustee’s own rights, duties or immunities
under this Indenture or otherwise. 
 Any supplemental indenture authorized by the provisions of this Section may be executed without the
consent of the Holders of any of the Notes then outstanding, notwithstanding any of the provisions of Section 9.02. 
 Section 9.02. Amendments and Supplemental Indentures with Consent of Holders of Notes. 
 Except as provided below in
this Section 9.02, with the consent of the Holders of not less than a majority in aggregate principal amount of the Notes then outstanding voting as one class (including, without limitation, consents obtained in connection with purchase of, or
tender or exchange offers for, the Notes), the Company, when authorized by a Board Resolution (which resolution may provide general terms or parameters for such action and may provide that the specific terms of such action may be determined in
accordance with or pursuant to an Officers’ Certificate), and the Trustee may, from time to time and at any time, amend this Indenture or enter into an indenture or indentures supplemental hereto (which shall conform to the provisions of the
TIA as in force at the date of execution thereof) for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or of any supplemental indenture or of modifying in any manner the rights
of the Holders of the Notes; and, subject to Sections 6.04 and 6.07 hereof, any existing Default or Event of Default (other than an uncured Default or Event of Default in the payment of principal, premium or interest on the Notes, except a payment
default resulting from an acceleration that has been rescinded) and compliance with any provision of the Indenture or the Notes may be waived with the consent of the Holders of not less than a majority in principal amount of the then-outstanding
Notes, voting as one class (including, without limitation, consents obtained in connection with a purchase of, or tender or exchange offer for, the Notes); provided, however, that without the consent of each Holder affected, an
amendment or waiver under this Section 9.02 may not (but only with respect to any Notes held by a non-consenting Holder): 
  

	 	(1)	change the stated final maturity of any Note; 

  

	 	(2)	reduce the principal amount of any Note; 

  

	 	(3)	reduce the rate or amend or modify the calculation, or time of payment, of interest, including defaulted interest on the Notes; 

  

	 	(4)	reduce or alter the method of computation of any amount payable on redemption, prepayment or purchase of any Note (or the time at which any such redemption, prepayment or purchase
may be made) or otherwise alter or waive any of the provisions with respect to the redemption of Notes (other than the provisions of Sections 3.07 and 4.09 hereof), or waive a redemption payment (other than payment required by Sections 3.07 and 4.09
hereof) with respect to any Note; 

  

 60 

	 	(5)	make the principal thereof, or interest, including Additional Interest, thereon payable in any coin or currency other than provided in the Notes or in accordance with the terms of
the Notes and this Indenture; 

  

	 	(6)	impair the right to institute suit for the enforcement of any payment on any Note when due, or otherwise make any change in the provisions of this 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 (including Additional Interest) on the Notes; or 

  

	 	(7)	reduce the percentage of principal amount of Notes whose Holders must consent to an amendment, supplement or waiver. 

 The Holders of the Notes affected thereby shall thereafter be determined, exercised and enforced hereunder subject in all respects to such modifications and amendments,
and all the terms and conditions of any such amendment, waiver or supplemental indenture shall be and shall be deemed to be part of the terms and conditions of this Indenture for any and all purposes. 
 Upon the request of the Company, accompanied by a copy of a resolution of the Board of Directors (which resolution may provide general terms or
parameters for such action and may provide that the specific terms of such action may be determined in accordance with or pursuant to an Officers’ Certificate) certified by the secretary or an assistant secretary of the Company authorizing the
execution of any such supplemental indenture, and upon the filing with the Trustee of evidence of the consent of the Holders of the Notes as aforesaid, the Trustee shall join with the Company in the execution of such supplemental indenture unless
such supplemental indenture affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may at its discretion, but shall not be obligated to, enter into such supplemental indenture.

 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 supplemental indenture, but it shall be sufficient if such consent shall approve the substance thereof. 
 Promptly after the
execution by the Company and the Trustee of any supplemental indenture pursuant to the provisions of this Section 9.02, the Company (or the Trustee at the request and expense of the Company) shall give notice thereof to the Holders of then
outstanding Notes affected thereby, as provided in Section 11.02. Any failure of the Company to give such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such supplemental indenture.

 Section 9.03. Effect of Supplemental Indenture, Amendment or Waiver. 
 Upon the execution of any supplemental indenture pursuant to the provisions hereof, or any amendment to or waiver of the provisions of the Indenture,
this Indenture shall be and shall 

  

 61 

 
be deemed to be modified and amended in accordance therewith and the respective rights, limitations of rights, obligations, duties and immunities under this
Indenture of the Trustee, the Company and the Holders of Notes affected thereby shall thereafter be determined, exercised and enforced hereunder subject in all respects to such modifications and amendments, and all the terms and conditions of any
such supplemental indenture, amendment or waiver shall be and shall be deemed to be part of the terms and conditions of this Indenture for any and all purposes. 
 Section 9.04. Conformity with Trust Indenture Act. 
 Every amendment or supplement to this
Indenture or the Notes shall be set forth in an amended or supplemental indenture executed pursuant to this Article that shall conform to the requirements of the TIA as then in effect if this Indenture shall then be qualified under the TIA.

 Section 9.05. Revocation and Effect of Consents. 
 Until an amendment, waiver or a supplemental indenture 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 9.06. Notation on or Exchange of Notes. 
 Notes authenticated and delivered after the execution of any supplemental indenture, amendment or waiver pursuant to the provisions of this Article 9 may
bear a notation in form approved by the Trustee as to any matter provided for by such supplemental indenture or as to any action taken by the Holders of Notes. If the Company or the Trustee shall so determine, new Notes so modified as to conform, in
the opinion of the Trustee and the Company, to any modification of this Indenture contained in any such supplemental indenture may be prepared and executed by the Company, authenticated by the Trustee and delivered in exchange for the Notes then
outstanding. 
 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 9.07. 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. In executing any amended or supplemental indenture, the Trustee shall be provided with and (subject to Section 7.01 hereof) shall be fully protected in relying upon, in
addition to the documents required by Section 12.04 hereof, an Officer’s Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by this Indenture.

combination of cash in U.S. dollars and non-callable Government Securities, in amounts as will be sufficient without consideration of any reinvestment of interest, to pay and discharge the entire indebtedness on the Notes not delivered to the
Trustee for cancellation for the principal amount and premium, if any, plus accrued interest and Additional Interest, if any, on all Notes; and 

  

	 	(2)	no Default or Event of Default has occurred and is continuing on the date of the deposit or will occur as a result of the deposit and the deposit will not result in a breach or

need not be segregated from other funds except to the extent required by law. 
 If the Trustee or Paying Agent is unable to apply any money
or Government Securities in accordance with Section 11.01 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the
Company’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 11.01; provided that if the Company has made any payment of principal of and premium, if
any, and interest and Additional Interest, if any, on any Notes because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or Government
Securities held by the Trustee or Paying Agent.

 7.25% Senior Notes Due 2019 
 Capitalized terms used herein shall have the meanings assigned to them in the
Indenture referred to below unless otherwise indicated. 
 1. Interest. American Tower Corporation, a Delaware corporation (the
“Company”), promises to pay interest on the principal amount of this Note at 7.25% per annum from June 10, 2009 until maturity and to pay the Additional Interest, if any, payable pursuant to the Registration Rights Agreement
referred to below. The Company will pay interest semi-annually in arrears on May 15 and November 15 of each year commencing on November 15, 2009, or if any such day is not a Business Day, on the next succeeding Business Day (each, an
“Interest Payment Date”). Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of issuance; provided that if there is no existing Default in the
payment of interest, the Company shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and premium and Additional Interest, if any, from time to time on demand at a rate that is
1% per annum in excess of the rate then in effect; it shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace periods) from
time to time on demand at the same rate to the extent lawful. Interest (other than Additional Interest) will be computed on the basis of a 360-day year of twelve 30-day months. 
 2. Method of Payment. The Company will pay interest on the Notes (except defaulted interest) to the Persons who are registered Holders of Notes at
the close of business on the May 1 or November 1 next preceding the Interest Payment Date (each, a “Regular Record Date”), even if such Notes are canceled after such record date and on or before such Interest Payment Date, except
as provided in Section 2.12 of the Indenture with respect to defaulted interest. The Notes will be payable as to principal, premium, if any, and interest and Additional Interest, if any, at the office or agency of the Paying Agent and Registrar
maintained for such purpose within the City and State of New York, or, at the option of the Company, payment of interest and Additional Interest, if any, may be made by check mailed to the Holders at their addresses set forth in the register of
Holders, and provided that payment by wire transfer of immediately available funds will be required with respect to principal of, premium, if any, and interest and Additional Interest, if any, on, all Global Notes and all other Notes the
Holders of which shall have provided wire transfer instructions to the Company or the Paying Agent. Such payment shall be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and
private debts. 
 3. Paying Agent and Registrar. Initially, The Bank of New York Mellon Trust Company, N.A., the Trustee under the
Indenture, will act as Paying Agent and Registrar. The Company may change any Paying Agent or Registrar without notice to any Holder. The Company or any of its Subsidiaries may act in any such capacity. 
 4. Indenture. The Company issued the Notes under an Indenture dated as of June 10, 2009 (the “Indenture”) between the Company and
the Trustee. The terms of the Notes 

  

 A-6 

 
include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (15 U.S. Code
§§ 77aaa-77bbbb) (the “Trust Indenture Act”). The Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms. To the extent any provision of this Note conflicts with
the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. The Notes are obligations of the Company. The Original Notes are limited to $300 million in aggregate principal amount. Unless the context
otherwise requires, the Original Notes and the Exchange Notes shall constitute one series for all purposes under the Indenture, including without limitation, amendments, waivers, redemptions and Change of Control Offers. Subject to the conditions
set forth in the Indenture and without the consent of the Holders, the Company may issue Additional Notes. All Notes, including any Additional Notes, will be treated as a single class of securities under the Indenture. 
 5. Optional Redemption. This Note is redeemable at the Company’s election, in whole or in part, at any time at a redemption price equal to
the greater of: 
  

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

  

	 	(2)	as determined by an Independent Investment Banker, the sum of the present values of the remaining scheduled payments of interest on the Notes to be redeemed (not including any
portion of such payments of interest accrued to the date of redemption) discounted to the redemption date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate, plus 50 basis points;

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

 If the Company selects a redemption date that is on or after a Regular Record Date and on or before the related interest payment date, the
accrued and unpaid interest, if any, shall be paid to the person in whose name the Note is registered at the close of business on such record date. 
 The Company will mail or caused to be mailed a notice of redemption at least 30 days, but not more than 60 days, before the redemption date to each Holder of the Notes to be redeemed at its registered address, except that redemption notices
may be mailed more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of the Indenture. Notices of redemption may not be conditional. 
 Unless the Company defaults in payment of the redemption price, on and after the redemption date, interest will cease to accrue on the Notes or portions
thereof called for redemption. Notes called for redemption become due on the date fixed for redemption. 
 For purposes of the foregoing, the
following terms shall have the following meanings: 
 “Adjusted Treasury Rate” means, with respect to any redemption date:

  

	 	(1)	the yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently published statistical release designated
“H.15(519)” or any successor publication which is published weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded United States Treasury securities adjusted to constant maturity
under the caption “Treasury Constant Maturities,” for the maturity corresponding to the Comparable Treasury Issue (as defined below) (if no maturity is within three months before or after the Remaining Life (as defined below), yields for
the two published maturities most closely corresponding to the Comparable Treasury Issue shall be determined and the Adjusted Treasury Rate shall be interpolated or extrapolated from such yields on a straight line basis, rounding to the nearest
month); or 

  

 A-7 

	 	(2)	if such release (or any successor release) is not published during the week preceding the calculation date or does not contain such yields, the rate per annum equal to the
semi-annual equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price (as defined below) for
such redemption date. 

 The Adjusted Treasury Rate shall be calculated on the third Business Day preceding the redemption date.

 “Comparable Treasury Issue” means the United States Treasury security selected by an Independent Investment Banker (as
defined below) as having a maturity comparable to the remaining term of the Notes 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 the Notes (“Remaining Life”). 
 “Comparable Treasury Price” means, for
any redemption date, (1) the average of four Reference Treasury Dealer Quotations (as defined below) for such redemption date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (2) if the Independent
Investment Banker obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such quotations. 
 “Independent Investment Banker” means one of the Reference Treasury Dealers appointed by the Company. 
 “Reference Treasury Dealer” means any of the primary U.S. Government securities dealers in New York City. 
 “Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Independent Investment Banker, of the bid and asked prices for the
Comparable Treasury Issue (expressed in each case as 

  

 A-8 

 
a percentage of its principal amount) quoted in writing to the Independent Investment Banker at 5:00 p.m., New York City time, on the third Business Day
preceding such redemption date. 
 6. No Mandatory Redemption. The Company shall not be required to make mandatory redemption payments
with respect to the Notes. 
 7. Repurchase at Option of Holder. Upon the occurrence of a Change of Control Triggering Event, and
subject to certain conditions set forth in the Indenture, the Company will be required to offer to purchase all of the outstanding Notes at a purchase price equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any,
thereon to the date of repurchase. 
 8. Notice of Redemption. Notice of redemption shall be mailed at least 30 days but not more than
60 days before the redemption date to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be mailed more than 60 days prior to a redemption date if the notice is issued in connection with Article
8 or Article 13 of the Indenture. Notes in denominations larger than $2,000 may be redeemed in part but only in whole multiples of $1,000, unless all of the Notes held by a Holder are to be redeemed. Unless the Company defaults in payment of the
redemption price, on and after the redemption date interest ceases to accrue on Notes or portions thereof called for redemption. 
 9.
Denominations, Transfer, Exchange. The Notes are in registered form without coupons in denominations of $2,000 and integral multiples of $1,000 thereafter. The transfer of Notes may be registered and Notes may be exchanged as provided in the
Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Company may require a Holder to pay any taxes and fees required by law or permitted by the
Indenture. The Company need not exchange or register the transfer of any Note or portion of a Note selected for redemption, except for the unredeemed portion of any Note being redeemed in part. Also, the Company need not exchange or register the
transfer of any Notes for a period of 15 days before a selection of Notes to be redeemed or during the period between a record date and the corresponding Interest Payment Date. 
 10. Persons Deemed Owners. The registered Holder of a Note may be treated as its owner for all purposes, except as provided in
Section 2.06(a) of the Indenture. 
 11. Amendment, Supplement and Waiver. The Indenture or the Notes may be amended or
supplemented as provided in the Indenture. 
 12. Defaults and Remedies. The Events of Default relating to the Notes are defined in
Section 6.01 of the Indenture. If any Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the then outstanding Notes may declare the principal, premium, if any, interest and any other
monetary obligations on all the then outstanding 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, all outstanding Notes will become
due and payable immediately without further action or notice. 
  

 A-9 

 Holders may not enforce the Indenture or the Notes except as provided in the Indenture. Subject to
certain limitations, Holders of a majority in aggregate principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of the Notes notice of any continuing Default
(except a Default relating to the payment of principal, premium, if any, or interest) if it determines that withholding notice is in their interest. The Holders of a majority in aggregate principal amount of the Notes then outstanding by notice to
the Trustee may on behalf of the Holders of all of the Notes waive any existing Default or and its consequences under the Indenture except a continuing Default in payment of the principal of, premium, if any, or interest, including Additional
Interest, if any, on, any of the Notes held by a non-consenting Holder. The Company is required to deliver to the Trustee annually a statement regarding compliance with the Indenture, and the Company is required upon becoming aware of any Default or
Event of Default, to deliver to the Trustee a statement specifying such Default or Event of Default. 
 13. Trustee Dealings with
Company. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not the
Trustee. 
 14. No Recourse Against Others. A director, officer, employee, incorporator or stockholder, of the Company, as such, shall
not have any liability for any obligations of the Company under the 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. The waiver and release are part of the consideration for the issuance of the Notes.

Securities tendered in accordance with section (c) below prior thereto in the Registered Exchange Offer. 
 (c) In connection with the
Registered Exchange Offer, if an Exchange Offer Registration Statement is required to be filed and becomes effective pursuant to Section 2(a) above, the Company shall:

letter of transmittal and related documents; 
  

 5 

 (ii) keep the Registered Exchange Offer open for not less than 20 Business Days after the
date notice thereof is mailed to the Holders (or, in each case, longer if required by applicable law);

during the Exchange Offer Registration Period; 
 (iv) utilize the services of a depositary for the Registered Exchange Offer
with an address in the Borough of Manhattan in New York City, which may be the Trustee or an Affiliate of the Trustee;

permit Holders to withdraw tendered Securities at any time prior to the close of business, New York time, on the last Business Day on which the Registered Exchange Offer is open; and 
 (vi) comply in all material respects with all applicable laws. 
 (d) As soon as practicable after the close of any Registered Exchange Offer, the Company shall: 
 (i) accept for exchange all Securities tendered and not validly withdrawn pursuant to the Registered Exchange Offer; 
 (ii) deliver to the Trustee for cancellation in accordance with Section 4(s) hereof all Securities so accepted for exchange; and

 (iii) cause the Trustee promptly to authenticate and deliver to each Holder of Securities, New Securities in an amount
equal to the principal amount of the Securities of such Holder so accepted for exchange. 
 (e) Each Holder participating in the Registered
Exchange Offer shall be required to represent to the Company that at the time of consummation of the Registered Exchange Offer: 
 (i) any New Securities received by such Holder will be acquired in the ordinary course of business; 
 (ii) such
Holder will have no arrangement or understanding with any Person to participate in the distribution of the Securities or the New Securities within the meaning of the Act; and 
 (iii) such Holder is not an Affiliate of the Company; 
 (iv) if such Holder is not a Broker-Dealer, that it is not engaged in, and does not intend to engage in, the distribution of the New
Securities; and 
  

 6 

 (v) if such Holder is a Broker-Dealer, that it will receive New Securities for its own
account in exchange for Securities that were acquired as a result of market-making activities or other trading activities and that it will be required to acknowledge that it will deliver a prospectus in connection with any resale of such New
Securities. 
 (f) If any Purchaser determines that it is not eligible to participate in the Registered Exchange Offer with respect to the
exchange of Securities constituting any portion of an unsold allotment, at the request of such Purchaser, the Company shall issue and deliver to such Purchaser or the Person purchasing New Securities registered under a Shelf Registration Statement
as contemplated by Section 3 hereof from such Purchaser, in exchange for such Securities, a like principal amount of New Securities. The Company shall use its reasonable best efforts to cause the CUSIP Service Bureau to issue the same CUSIP
number for such New Securities as for New Securities issued pursuant to the Registered Exchange Offer, which will be the same CUSIP number as the Existing Notes. 
 3. Shelf Registration. 
 (a) If (A) an Exchange Offer Registration Statement
is required to be filed and become effective pursuant to Section 2(a) above, and: (i) due to any change in law or applicable interpretations thereof by the Commission’s staff, the Company determines upon advice of its outside counsel
that it is not permitted to effect the Registered Exchange Offer as contemplated by Section 2 hereof, or (ii) for any other reason the Registered Exchange Offer is not consummated by the 45th day after the Effective Time of the Exchange Offer Registration Statement (or such longer period as required by applicable law)
(or, if such 45th day is not a Business Day, the next succeeding Business Day) or
the Exchange Offer Registration Statement does not become effective by the Registration Trigger Date; or (B) any Holder of Securities notifies the Company prior to the 20th day following the consummation of any Registered Exchange Offer that: (i) it is prohibited by law or policy of the Commission
from participating in the Registered Exchange Offer; (ii) it may not resell the New Securities acquired by it in the Registered Exchange Offer to the public without delivering a prospectus and the prospectus contained in the Registered Exchange
Offer is not appropriate or available for such resales or (iii) that it is a Broker-Dealer and owns Securities acquired directly from the Company or an affiliate of the Company, the Company shall effect a Shelf Registration Statement in
accordance with subsection (b) below. Notwithstanding anything to the contrary, the requirements to file a Shelf Registration Statement and to have such Shelf Registration Statement become effective and remain effective shall terminate at such
time as all of the Securities are Freely Tradeable. 
 (b) If a Shelf Registration Statement is required to be filed and becomes effective
pursuant to this Section 3, 
 (i) The Company shall as promptly as practicable file with the Commission and thereafter
cause to become effective under the Act a Shelf Registration Statement relating to the offer and sale of the Securities or the New Securities, as applicable, by the Holders thereof from time to time in accordance with the methods of distribution
elected by such Holders and set forth in such Shelf Registration Statement; provided, however, that no Holder (other than a Purchaser) shall be entitled to have the 

  

 7 

 
Securities held by it covered by such Shelf Registration Statement unless such Holder agrees in writing to be bound by all of the provisions of this
Agreement applicable to such Holder; and provided further, that with respect to New Securities received by a Purchaser in exchange for Securities constituting any portion of an unsold allotment, the Company may, if permitted by current
interpretations by the Commission’s staff, file a post-effective amendment to the Exchange Offer Registration Statement containing the information required by Item 507 or 508 of Regulation S-K, as applicable, in satisfaction of its
obligations under this subsection with respect thereto, and any such Exchange Offer Registration Statement, as so amended, shall be referred to herein as, and governed by the provisions herein applicable to, a Shelf Registration Statement.
Notwithstanding anything in this Section 3, Additional Interest shall accrue only in accordance with the provisions of Section 6 hereof. 
 (ii) The Company shall use its reasonable best efforts to keep the Shelf Registration Statement continuously effective, supplemented and amended as required by the Act, in order to permit the Prospectus forming part
thereof to be usable by Holders for a period of two years from the Issue Date or such shorter period that will terminate on: (i) such date as all the Registrable Securities covered by the Shelf Registration Statement have been sold, or
(ii) the date that all the Registrable Securities covered by the Shelf Registration Statement are Freely Tradeable (such period being called the “Shelf Registration Period”). The Company shall be deemed not to have used its reasonable
best efforts to keep the Shelf Registration Statement effective during the requisite period if it voluntarily takes any action that would result in Holders of Securities covered thereby not being able to offer and sell such Securities during that
period, unless (A) such action is required by applicable law; or (B) such action is taken by the Company in good faith and for valid business reasons (not including avoidance of the Company’s obligations hereunder), including the
acquisition or divestiture of assets, a merger or financing so long as the Company promptly thereafter complies with the requirements of Section 4(k) hereof, if applicable. 
 (c) Not less than 30 days prior to the Effective Time of any Shelf Registration Statement that may be required under this Agreement, the Company shall
mail the Notice and Questionnaire (the “Notice and Questionnaire”) substantially in the form attached as Annex E hereto to the Holders of Registrable Securities; no Holder shall be entitled to be named as a selling securityholder in the
Shelf Registration Statement as of the Effective Time, and no Holder shall be entitled to use the prospectus forming a part thereof for resales of Securities at any time, unless such Holder has returned a completed and signed Notice and
Questionnaire to the Company by the deadline for response set forth therein; provided, however, that Holders of Registrable Securities shall have at least 28 days from the date on which the Notice and Questionnaire is first mailed to
such Holders to return a completed and signed Notice and Questionnaire to the Company. 
 (d) After the Effective Time of any Shelf
Registration Statement that may be required to be filed under this Agreement, Holders of Registrable Securities who did not timely return a Notice and Questionnaire to the Company may return a Notice and Questionnaire at any time and may request to
be included in such Shelf Registration Statement. If: 
 (i) the Company can include such Holder with respect to its
Registrable Securities by means of a prospectus supplement filed pursuant to Rule 424(b) of the Act or by means of a registration statement filed pursuant to Rule 462(b) of the Act, then the Company shall file such Rule 424(b)
supplement or Rule 462(b) registration statement with the Commission within 10 Business Days of its receipt of the Notice and Questionnaire; 
  

 8 

 (ii) the Company, in the opinion of its counsel, cannot include such Holder with respect
to its Registrable Securities by means of a prospectus supplement to the prospectus contained as part of such effective Shelf Registration Statement or by means of a related registration statement filed pursuant to Rule 462(b) of the Act, the
Company shall promptly take any action reasonably necessary to enable such a Holder to use a registration statement for resale of Registrable Securities, including, without limitation, any action necessary to identify such Holders or selling
securityholder in a post-effective amendment to the Shelf Registration Statement or new Shelf Registration Statement which the Company shall promptly file and cause to become effective to cover the resale of the Registrable Securities that are the
subject of such request. If the Company is required to file such post-effective amendment to the Shelf Registration Statement or a new Shelf Registration Statement for the sole purpose of adding Holders to the Shelf Registration Statement, the
Company shall not be required to file such post-effective amendment or new Shelf Registration Statement more frequently than once every calendar quarter. 
 (e) In the event of a Shelf Registration Statement, in addition to the information required to be provided in the Notice and Questionnaire, the Company may require Holders to furnish to the Company additional
information regarding such Holder and such Holder’s intended method of distribution of Securities as may be required in order to comply with the Securities Act. Each Holder agrees to notify the Company as promptly as practicable of any
inaccuracy or change in information previously furnished by such Holder to the Company or of the occurrence of any event in either case as a result of which any prospectus relating to the Shelf Registration Statement contains or would contain an
untrue statement of a material fact regarding such Holder or such Holder’s intended method of disposition of such Securities or omits to state any material fact regarding such Holder or such Holder’s intended method of disposition of such
Securities required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing, and promptly to furnish to the Company any such required additional information so that such prospectus
shall not contain, with respect to such Holder or the disposition of such Securities, an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in
light of the circumstances then existing. 
 4. Additional Registration Procedures. In connection with any Shelf Registration
Statement and any Exchange Offer Registration Statement, in either case to the extent applicable, the following provisions shall apply. 
 (a) The Company shall: 
 (i) furnish to the Representatives and to counsel for the Holders (if any), not less than
five Business Days prior to the filing thereof with the Commission, a copy of any Exchange Offer Registration Statement and any Shelf Registration Statement, and each amendment thereof and each amendment or supplement, if any, to the Prospectus
included therein (including all documents incorporated by reference therein after the initial filing) and shall use its reasonable best efforts to reflect in each such document, when so filed with the Commission, such comments as the Representatives
or such counsel for the Holders (if any) reasonably proposes; 
  

 9 

 (ii) include the information in substantially the form set forth in Annex A hereto on the
facing page of the Exchange Offer Registration Statement, in Annex B hereto in the forepart of the Exchange Offer Registration Statement in a section setting forth details of the Registered Exchange Offer, in Annex C hereto in the underwriting or
plan of distribution section of the Prospectus contained in the Exchange Offer Registration Statement, and in Annex D hereto in the letter of transmittal delivered pursuant to the Registered Exchange Offer; 
 (iii) if requested by a Purchaser, include the information required by Item 507 or 508 of Regulation S-K, as applicable, in the
Prospectus contained in the Exchange Offer Registration Statement; and 
 (iv) in the case of a Shelf Registration Statement,
include the names of the Holders that propose to sell Securities pursuant to the Shelf Registration Statement as selling security holders. 
 (b) The Company shall ensure that: 
 (i) any Registration Statement and any amendment thereto and any Prospectus
forming part thereof and any amendment or supplement thereto complies in all material respects with the Act and the rules and regulations thereunder; and 
 (ii) any Registration Statement and any amendment thereto does not, when it becomes effective, contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary
to make the statements therein not misleading; it being understood that, with respect to the information about Holders in any Shelf Registration Statement, the Company will be relying solely on responses provided by Holders to the Notice and
Questionnaire. 
 (c) The Company shall advise the Representatives, and, to the extent the Company has been provided a telephone or facsimile
number and address for notices (and their respective designated counsel, if any), the Holders of Securities covered by any Shelf Registration Statement and any Exchanging Dealer under any Exchange Offer Registration Statement and, if requested by
you or any such Holder or Exchanging Dealer, shall confirm such advice in writing (which notice pursuant to clauses (ii)-(v) hereof shall be accompanied by an instruction to suspend the use of the Prospectus until the Company shall have
remedied the basis for such suspension): 
 (i) when a Registration Statement and any amendment thereto has been filed with
the Commission and when the Registration Statement or any post-effective amendment thereto has become effective; 
  

 10 

 (ii) of any request by the Commission for any amendment or supplement to the Registration
Statement or the Prospectus or for additional information; 
 (iii) of the issuance by the Commission of any stop order
suspending the effectiveness of the Registration Statement or the initiation of any proceedings for that purpose, of the issuance by the Commission of any notification of objection to the use of the form on which the Registration Statement has been
filed, and of the happening of any event that causes the Company to become an “ineligible issuer,” as defined in Commission Rule 405; 
 (iv) of the receipt by the Company of any notification with respect to the suspension of the qualification of the securities included therein for sale in any jurisdiction or the initiation of any proceeding for such
purpose; and 
 (v) of the happening of any event that requires any change in the Registration Statement or the Prospectus so
that, as of such date, the statements therein are not misleading and do not omit to state a material fact required to be stated therein or necessary to make the statements therein (in the case of the Prospectus, in the light of the circumstances
under which they were made) not misleading. 
 Each Holder of Securities agrees by acquisition of such Securities that, upon actual receipt
of any notice from the Company of the happening of any event of the kind described in Section 4(c)(ii), (iii), (iv), and (v) hereof, such Holder will forthwith discontinue any and all dispositions of such Securities by means of the
Registration Statement or Prospectus until such Holder’s receipt of the copies of the supplemented or amended Prospectus contemplated by Section 4(b), or until it is advised in writing (the “Advice”) by the Company that the use
of the applicable Prospectus may be resumed, and has received copies of any amendments or supplements thereto; provided, however, that this paragraph shall not prohibit any Holder from engaging in dispositions of the Securities through
means other than pursuant to the Registration Statement or Prospectus, as long as such dispositions comply with applicable laws. 
 (d) The
Company shall use its reasonable best efforts to obtain the withdrawal of any order suspending the effectiveness of any Registration Statement or the qualification of the securities therein for sale in any jurisdiction at the earliest possible time.

 (e) The Company shall furnish, upon written request, to each Holder of Securities covered by any Shelf Registration Statement, without
charge, at least one copy of such Shelf Registration Statement and any post-effective amendment thereto, including all material incorporated therein by reference and, if requested, all exhibits thereto (including exhibits incorporated by reference
therein). 
 (f) The Company shall, during the Shelf Registration Period, deliver to each Holder of Securities covered by any Shelf
Registration Statement and its respective counsel, 

  

 11 

 
without charge, as many copies of the Prospectus (including each preliminary Prospectus) included in such Shelf Registration Statement and any amendment or
supplement thereto as such Holder may reasonably request. The Company consents to the use of the Prospectus or any amendment or supplement thereto by each of the selling Holders of securities in connection with the offering and sale of the
securities covered by the Prospectus, or any amendment or supplement thereto, included in the Shelf Registration Statement. 
 (g) The
Company shall furnish to each Exchanging Dealer which so requests, without charge, at least one copy of the Exchange Offer Registration Statement and any post-effective amendment thereto, including all material incorporated by reference therein,
and, if the Exchanging Dealer so requests in writing, all exhibits thereto (including exhibits incorporated by reference therein). 
 (h) The
Company shall promptly deliver to each Purchaser, each Exchanging Dealer and each other Person required to deliver a Prospectus during any Exchange Offer Registration Period, without charge, as many copies of the Prospectus included in such Exchange
Offer Registration Statement and any amendment or supplement thereto as any such Person may reasonably request. The Company consents to the use of the Prospectus or any amendment or supplement thereto by any Purchaser, any Exchanging Dealer and any
such other Person that may be required to deliver a Prospectus following any Registered Exchange Offer in connection with the offering and sale of the New Securities covered by the Prospectus, or any amendment or supplement thereto, included in any
Exchange Offer Registration Statement. 
 (i) Prior to any Registered Exchange Offer or any other offering of Securities pursuant to any
Registration Statement, the Company shall arrange, if necessary, for the qualification of the Securities or the New Securities for sale under the laws of such jurisdictions as any Holder shall reasonably request and will maintain such qualification
in effect so long as required; provided that in no event shall the Company be obligated to qualify to do business in any jurisdiction where it is not then so qualified or to take any action that would subject it to service of process in suits, other
than those arising out of the Initial Placement, any Registered Exchange Offer or any offering pursuant to a Shelf Registration Statement, in any such jurisdiction where it is not then so subject or otherwise subject itself to taxation in any such
jurisdiction. 
 (j) The Company shall cooperate with the Holders of Securities to facilitate the timely preparation and delivery of
certificates representing New Securities or Securities to be issued or sold pursuant to any Registration Statement free of any restrictive legends and in such denominations and registered in such names as Holders may request. 
 (k) Upon the occurrence of any event contemplated by subsections (c)(ii) through (v) above, the Company shall promptly prepare a post-effective
amendment to the applicable Registration Statement or an amendment or supplement to the related Prospectus or file any other required document so that, as thereafter delivered to Purchasers of the securities included therein, the Prospectus will not
include an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, however, that the

  

 12 

 
Company may delay preparing, filing and distributing any such supplements or amendments (and continue the suspension of the use of the prospectus) if the
Company determines in good faith that such supplement or amendment would, in the reasonable judgment of the Company, (i) interfere with or affect the negotiation or completion of a transaction that is being contemplated by the Company (whether
or not a final decision has been made to undertake such transaction) or (ii) involve initial or continuing disclosure obligations that are not in the best interests of the Company’s shareholders at such time; provided,
further, that neither such delay nor such suspension with respect to all matters in clause (i) or (ii) shall extend for a period of more than 30 days in any three-month period or more than 90 days for all such periods in any
twelve-month period and shall not affect the Company’s obligations to pay Additional Interest as contemplated by Section 6 hereof. 
 (l) In such circumstances, the period of effectiveness of any Exchange Offer Registration Statement provided for in Section 2 and any Shelf Registration Statement provided for in Section 3(b) shall each be extended by the number
of days from and including the date of the giving of a notice of suspension pursuant to Section 4(c) to and including the date when the Purchasers, the Holders of the Securities and any known Exchanging Dealer shall have received such amended
or supplemented Prospectus pursuant to this Section. 
 (m) Not later than the effective date of any Registration Statement, the Company
shall provide CUSIP numbers for the Securities or the New Securities, as the case may be, registered under such Registration Statement and provide the Trustee with printed certificates for such Securities or New Securities, in a form eligible for
deposit with The Depository Trust Company. 
 (n) The Company shall comply with all applicable rules and regulations of the Commission and
shall make generally available to its security holders no later than 45 days after the end of any 12-month period (or 90 days after the end of any 12-month period if such period is a fiscal year), an earnings statement satisfying the
provisions of Section 11(a) of the Act and Rule 158 thereunder (or any similar rule under the Act) for a period of at least 12 months beginning on the first day of the first fiscal quarter after the effective date of the applicable
Registration Statement. 
 (o) The Company shall cause the Indenture, to be qualified under the Trust Indenture Act in a timely manner;

 (p) The Company may require each Holder of securities to be sold pursuant to any Shelf Registration Statement to furnish to the Company
such information regarding the Holder and the distribution of such securities as the Company may from time to time reasonably require for inclusion in such Registration Statement. The Company may exclude from such Shelf Registration Statement the
Securities of any Holder that fails to furnish such information within a reasonable time after receiving such request. 
 (q) In the case of
any Shelf Registration Statement, the Company shall enter into such agreements and take all other appropriate actions (including if requested an underwriting agreement in customary form) in order to expedite or facilitate the registration or the
disposition of the Securities, and in connection therewith, if an underwriting agreement is 

  

 13 

 
entered into, cause the same to contain indemnification provisions and procedures no less favorable than those set forth in Section 7 (or such other
provisions and procedures acceptable to the Majority Holders and the Managing Underwriters, if any, with respect to all parties to be indemnified pursuant to Section 7). 
 (r) In the case of any Shelf Registration Statement, the Company shall: 
 (i) make reasonably available for inspection by the representatives or agents of the Holders of Securities designated by the Majority
Holders to be registered thereunder, any underwriter participating in any disposition pursuant to such Registration Statement, and any attorney, accountant or other agent retained by the Holders or any such underwriter all relevant and reasonably
requested financial and other records, pertinent corporate documents and properties of the Company and its subsidiaries; 
 (ii) cause the Company’s officers, directors and employees to supply all relevant information reasonably requested by the representatives or agents of the Holders of Securities designated by the Majority Holders or any such
underwriter, attorney, accountant or agent in connection with any such Registration Statement as is customary for similar due diligence examinations; provided, however, that any information that is designated in writing by the Company,
in good faith, as confidential at the time of delivery of such information shall be kept confidential by such representatives or agents or any such underwriter, attorney, accountant or agent, unless such disclosure is made in connection with a court
proceeding or required by law, or such information becomes available to the public generally or through a third party without an accompanying obligation of confidentiality; 
 (iii) make such representations and warranties to the Holders of Securities registered thereunder and the underwriters, if any, in form,
substance and scope as are customarily made by issuers to underwriters in primary underwritten offerings and covering matters including, but not limited to, those set forth in the Purchase Agreement; 
 (iv) obtain opinions of counsel to the Company and updates thereof (which counsel and opinions (in form, scope and substance) shall be
reasonably satisfactory to the Managing Underwriters, if any) addressed to each selling Holder and the underwriters, if any, covering such matters as are customarily covered in opinions requested in underwritten offerings and such other matters as
may be reasonably requested by such Holders and underwriters; 
 (v) obtain “cold comfort” letters and updates
thereof from the independent certified public accountants of the Company (and, if necessary, any other independent certified public accountants of any subsidiary of the Company or of any business acquired by the Company for which financial
statements and financial data are, or are required to be, included in the Registration Statement), addressed to each selling Holder of Securities registered thereunder and the underwriters, if any, who have provided such accountants with a
representation letter if required to do so under Statement on Auditing Standards No. 72 in customary form and covering matters of the type customarily covered in “cold comfort” letters in connection with primary underwritten
offerings; 
  

 14 

 (vi) deliver such documents and certificates as may be reasonably requested by the
Majority Holders and the Managing Underwriters, if any, including those to evidence compliance with Section 4(k) and with any customary conditions contained in the underwriting agreement or other agreement entered into by the Company; and

 (vii) after the Effective Time of the Shelf Registration Statement, upon the request of any Holder, promptly send a Notice
and Questionnaire to such Holder; provided that the Company shall not be required to take any action to name such Holder as a selling securityholder in the Shelf Registration Statement or to enable such holder to use the prospectus forming a part
thereof for resales of Securities except in accordance with Section 3(c) hereof. 
 The actions set forth in clauses (iii), (iv), (v) and
(vi) of this Section shall be performed at (A) the effectiveness of such Registration Statement and each post-effective amendment thereto; and (B) each closing under any underwriting or similar agreement as and to the extent required
thereunder. 
 (s) In the case of any Exchange Offer Registration Statement, the Company shall, if requested by the Purchasers: 

(i) make reasonably available for inspection by each Purchaser, and any attorney, accountant or other agent retained by such Purchaser,
all relevant financial and other records, pertinent corporate documents and properties of the Company and its subsidiaries; 
 (ii) cause the Company’s officers, directors and employees to supply all relevant information reasonably requested by such Purchaser or any such attorney, accountant or agent in connection with any such Registration Statement as is
customary for similar due diligence examinations; provided, however, that any information that is designated in writing by the Company, in good faith, as confidential at the time of delivery of such information shall be kept
confidential by such Purchaser or any such attorney, accountant or agent, unless such disclosure is made in connection with a court proceeding or required by law, or such information becomes available to the public generally or through a third party
without an accompanying obligation of confidentiality; 
 (iii) make such representations and warranties to such Purchaser, in
form, substance and scope as are customarily made by issuers to underwriters in primary underwritten offerings and covering matters including, but not limited to, those set forth in the Purchase Agreement; 
 (iv) obtain opinions of counsel to the Company and updates thereof (which counsel and opinions (in form, scope and substance) shall be
reasonably satisfactory to such Purchaser and its counsel) addressed to such Purchaser, covering such matters as are customarily covered in opinions requested in underwritten offerings and such other matters as may be reasonably requested by such
Purchaser or its counsel; 
  

 15 

 (v) obtain “cold comfort” letters and updates thereof from the independent
certified public accountants of the Company (and, if necessary, any other independent certified public accountants of any subsidiary of the Company or of any business acquired by the Company for which financial statements and financial data are, or
are required to be, included in the Registration Statement), addressed to such Purchaser, in customary form and covering matters of the type customarily covered in “cold comfort” letters in connection with primary underwritten offerings as
permitted by Statement on Auditing Standards No. 72, or if requested by such Purchaser or its counsel in lieu of a “cold comfort” letter, an agreed-upon procedures letter under Statement on Auditing Standards No. 35, covering
matters requested by such Purchaser or its counsel; and 
 (vi) deliver such documents and certificates as may be reasonably
requested by such Purchaser or its counsel, including those to evidence compliance with Section 4(k) and with conditions customarily contained in underwriting agreements. 
 The foregoing actions set forth in clauses (iii), (iv), (v) and (vi) of this Section shall be performed at the close of the Registered Exchange Offer and the effective date of any post-effective
amendment to the Exchange Offer Registration Statement. 
 (t) If a Registered Exchange Offer is to be consummated, upon delivery of the
Securities by Holders to the Company (or to such other Person as directed by the Company) in exchange for the New Securities, the Company shall mark, or caused to be marked, on the Securities so exchanged that such Securities are being canceled in
exchange for the New Securities. In no event shall the Securities be marked as paid or otherwise satisfied. 
 (u) The Company will use its
reasonable best efforts (i) if the Securities have been rated prior to the initial sale of such Securities, to confirm such ratings will apply to the Securities or the New Securities, as the case may be, covered by a Registration Statement; or
(ii) if the Securities were not previously rated, to cause the Securities covered by a Registration Statement to be rated with at least one nationally recognized statistical rating agency, if so requested by Majority Holders with respect to the
related Registration Statement or by any Managing Underwriters. 
 (v) In the event that any Broker-Dealer shall underwrite any Securities or
participate as a member of an underwriting syndicate or selling group or “assist in the distribution” (within the meaning of the Rules of Fair Practice and the By-Laws of the Financial Industry Regulatory Authority) thereof, whether as a
Holder of such Securities or as an underwriter, a placement or sales agent or a broker or dealer in respect thereof, or otherwise, assist such Broker-Dealer in complying with the requirements of such Rules and By-Laws, including, without limitation,
by: 
 (i) if such Rules or By-Laws shall so require, engaging a “qualified independent underwriter” (as defined in
such Rules) to participate in the preparation of 

  

 16 

 
the Registration Statement, to exercise usual standards of due diligence with respect thereto and, if any portion of the offering contemplated by such
Registration Statement is an underwritten offering or is made through a placement or sales agent, to recommend the yield of such Securities; 
 (ii) indemnifying any such qualified independent underwriter to the extent of the indemnification of underwriters provided in Section 7 hereof; and 
 (iii) providing such information to such Broker-Dealer as may be required in order for such Broker-Dealer to comply with the requirements
of such Rules. 
 (w) Prior to any public offering of the Securities or New Securities, pursuant to any Registration Statement, the Company
shall register or qualify or cooperate with the Holders of the Securities included therein and their respective counsel in connection with the registration or qualification of the Securities for offer and sale under the securities or “blue
sky” laws of such states of the United States as any Holder of the Securities reasonably requests in writing and do any and all other acts or things necessary or advisable to enable the offer and sale in such jurisdictions of the Securities
covered by such Registration Statement; provided, however, that the Company shall not be required to (i) qualify generally to do business in any jurisdiction where it is not then so qualified or (ii) take any action which would subject it
to general service of process or to taxation in any jurisdiction where it is not then so subject. 
 (x) The Company shall use its reasonable
best efforts to take all other steps necessary to effect the registration of the Securities or the New Securities, as the case may be, covered by a Registration Statement. 
 5. Registration Expenses. The Company shall bear all expenses incurred in connection with the performance of its obligations under
Sections 2, 3 and 4 hereof and, in the event of any Shelf Registration Statement, will reimburse the Holders for the reasonable fees and disbursements of one firm or counsel designated by the Majority Holders to act as counsel for the Holders
in connection therewith, and, in the case of any Exchange Offer Registration Statement, will reimburse the Purchasers for the reasonable fees and disbursements of one firm or counsel acting in connection therewith. Notwithstanding the foregoing, the
Holders shall pay all agency fees and commissions and underwriting discounts and commissions and the fees and disbursements of any counsel or other advisors or experts retained by such Holders (severally or jointly), other than the counsel
specifically referred to above. 
 6. Additional Interest Under Certain Circumstances. The Company, the Purchasers and each Holder of
Registrable Securities agree by acquisition of such Securities that the Holders of Registrable Securities will suffer damages if a Registration Default (as defined below) occurs and that it would not be feasible to ascertain the extent of such
damages with precision. Accordingly, the Company, the Purchasers and each Holder of Registrable Securities agree that the following additional interest provisions shall constitute liquidated damages in the event of a “Registration Default”
(as defined below) and shall constitute the sole remedy of the Purchasers and each Holder of Registrable Securities for any Registration Defaults. 
  

 17 

 (a) In accordance with the terms of the Securities, if as of the Registration Trigger Date, any of the
Securities are Registrable Securities, additional interest (“Additional Interest”) with respect to such Registrable Securities shall be assessed as follows if any of the following events occur (each such event in clauses (i) through
(iii) below being herein called a “Registration Default”): 
 (i) on or prior to the Registration Trigger Date,
neither the Exchange Offer Registration Statement nor the Shelf Registration Statement has become effective; 
 (ii) on or prior to the 45th day following Effective Time of the Exchange
Offer Registration Statement, the Registered Exchange Offer has not been consummated; or 
 (iii) any Registration Statement
required by this Agreement has become effective but (A) such Registration Statement thereafter ceases to be effective or (B) such Registration Statement or the related prospectus ceases to be usable in connection with resales of
Registrable Securities during the periods specified herein. 
 Each of the foregoing shall constitute a Registration Default whatever the
reason for any such event and whether it is voluntary or involuntary or is beyond the control of the Company or pursuant to operation of law or as a result of any action or inaction by the Commission; provided, however, that the
Company shall in no event be required to pay Additional Interest for more than one Registration Default at any given time. 
 Additional
Interest shall accrue on the Registrable Securities, from and including the date on which any such Registration Default shall occur to but excluding the date on which all such Registration Defaults shall have been cured or they cease to be
Registrable Securities (whichever is earlier), at a rate of 0.25% per annum (the “Additional Interest Amount”) for the first 90-day period immediately following the occurrence of such Registration Default. The Additional Interest
Amount will increase by 0.25% per annum at the end of such first 90-day period immediately following the date on which the first Registration Default shall occur until all such Registration Defaults have been cured, up to a maximum amount of
Additional Interest for all Registration Defaults of 0.50% per annum. 
 (b) Any amounts of Additional Interest due pursuant to
Section 6(a) shall be paid to the Holders entitled thereto on May 15 and November 15 of any given year as more fully set forth in the Indenture and the Notes. 
 7. Indemnification and Contribution. (a) The Company agrees to indemnify and hold harmless each Holder of Securities or New Securities, as
the case may be, covered by any Registration Statement (including each Purchaser and, with respect to any Prospectus delivery as contemplated in Section 4(h) hereof, each Exchanging Dealer), the directors, officers, employees and agents of each
such Holder, Purchaser or Exchanging Dealer and each Person who controls any such Holder, Purchaser or Exchanging Dealer within the meaning of either the Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or
several, to which they or any of them may become subject under the Act, the Exchange Act or other Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, 

  

 18 

 
damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact
contained in the Registration Statement as originally filed or in any amendment thereof, or in any preliminary Prospectus or the Prospectus, or in any amendment thereof or supplement thereto, or “issuer free writing prospectus,” as defined
in Commission Rule 433 (“Issuer FWP”), or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and
agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided,
however, that the Company will not be liable in any case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made
therein in reliance upon and in conformity with written information furnished to the Company by or on behalf of the party claiming indemnification specifically for inclusion therein and provided, further, that the Company shall not be
liable for any loss, claim, damage or expense (1) arising from any offer or sale of Securities or New Securities, as the case may be, covered by any Registration Statement, during a 30-day or 90 day period referenced in Section 5(k)
hereof, of which the Holder has received written notice, or (2) if the Holder fails to deliver, within the time required by the Securities Act, a Prospectus that is amended or supplemented, or, if permitted by Section 4(e), an Issuer FWP,
and such Prospectus, as amended or supplemented, or Issuer FWP, as the case may be, would have corrected the untrue statement or omission or alleged untrue statement or omission of a material fact contained in the Prospectus delivered by the Holder,
so long as the Prospectus, as amended or supplemented, or Issuer FWP, as the case may be, has been delivered to such Holder prior to such time. This indemnity agreement will be in addition to any liability which the Company may otherwise have.

 The Company also agrees to indemnify or contribute as provided in Section 7(d) to Losses of any underwriter of Securities or New
Securities, as the case may be, registered under a Shelf Registration Statement, their directors, officers, employees or agents and each Person who controls such underwriter on substantially the same basis as that of the indemnification of the
Purchasers and the selling Holders provided in this Section 7(a) and shall, if requested by any Holder, enter into an underwriting agreement reflecting such agreement, as provided in Section 4(p) hereof. 
 (b) Each Holder of securities covered by a Registration Statement (including each Purchaser and, with respect to any Prospectus delivery as contemplated
in Section 4(h) hereof, each Exchanging Dealer) severally, but not jointly, agrees to indemnify and hold harmless the Company, each of its directors, each of its officers who signs such Registration Statement and each Person who controls the
Company within the meaning of either the Act or the Exchange Act, to the same extent as the foregoing indemnity from the Company to each such Holder, but only with reference to written information relating to such Holder furnished to the Company by
or on behalf of such Holder specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity agreement will be in addition to any liability which any such Holder may otherwise have. 
 (c) Promptly after receipt by an indemnified party under this Section 7 of notice of the commencement of any action, such indemnified party will, if
a claim in respect 

  

 19 

 
thereof is to be made against the indemnifying party under this Section, notify the indemnifying party in writing of the commencement thereof; but the
omission to so notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party under subsection (a) or (b) above except to the extent it has been materially prejudiced (through the forfeiture
of substantive rights and defenses) by such failure and the omission to so notify the indemnifying party will not relieve it from any liability which it may have to an indemnified party otherwise than under subsection (a) or (b) above. The
indemnifying party shall be entitled to appoint counsel of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the
indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be reasonably
satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local
counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a
conflict of interest; (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal
defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party; (iii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to
represent the indemnified party within a reasonable time after notice of the institution of such action; or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party.
An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of
which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes (i) an unconditional release
of each indemnified party from all liability arising out of such claim, action, suit or proceeding and (ii) does not include a statement as to or an admission of fault or failure to act by or on behalf of any indemnified party. No indemnifying
party shall be liable under subsections (a), (b) or (c) of this Section for any settlement of any claim or action effected without its consent, which consent will not be unreasonably withheld; provided, however, that such
indemnifying party has notified in writing the indemnified party of its refusal to accept such settlement within 30 days of its receipt of a notice from the indemnified party outlining the terms of such settlement. 
 (d) In the event that the indemnity provided in paragraph (a) or (b) of this Section is unavailable to or insufficient to hold harmless an
indemnified party for any reason, then each applicable indemnifying party shall have a joint and several obligation to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in
connection with investigating or defending same) (collectively “Losses”) to which such indemnified party may be subject in such proportion as is appropriate to reflect the relative benefits received by such indemnifying party, on the one
hand, and such indemnified party, on the other hand, from the Initial Placement and the Registration Statement 

  

 20 

 
which resulted in such Losses; provided, however, that in no case shall any Purchaser of any Security or New Security be responsible, in the
aggregate, for any amount in excess of the purchase discount or commission applicable to such Security, or in the case of a New Security, applicable to the Security that was exchangeable into such New Security, as set forth in the Final Offering
Circular, nor shall any underwriter be responsible for any amount in excess of the underwriting discount or commission applicable to the securities purchased by such underwriter under the Registration Statement which resulted in such Losses, nor
shall any subsequent Holder of any Security or New Security be responsible, in the aggregate, for any amount in excess of the net proceeds received by such Holder from the resale of such securities under the Registration Statement which resulted in
such Losses. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the indemnifying party and the indemnified party shall contribute in such proportion as is appropriate to reflect not only such relative
benefits but also the relative fault of such indemnifying party, on the one hand, and such indemnified party, on the other hand, in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable
considerations. Relative fault shall be determined by reference to, among other things, whether any alleged untrue statement or omission relates to information provided by the indemnifying party, on the one hand, or by the indemnified party, on the
other hand, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The parties agree that it would not be just and equitable if contribution were
determined by pro rata allocation (even if the Holders were treated as one entity for such purpose) or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of
this paragraph (d), no Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. For purposes
of this Section, each Person who controls a Holder within the meaning of either the Act or the Exchange Act and each director, officer, employee and agent of such Holder shall have the same rights to contribution as such Holder, and each Person who
controls the Company within the meaning of either the Act or the Exchange Act, each officer of the Company who shall have signed the Registration Statement and each director of the Company shall have the same rights to contribution as the Company,
subject in each case to the applicable terms and conditions of this paragraph (d). 
 (e) The provisions of this Section will remain in
full force and effect, regardless of any investigation made by or on behalf of any Holder or the Company or any of the officers, directors or controlling Persons referred to in this Section hereof, and will survive the sale by a Holder of securities
covered by a Registration Statement. 
 8. Underwritten Registrations. In connection with any Shelf Registration Statement required
under this Agreement, the Company may enter into one or more underwriting agreements, engagement letters, agency agreements, “best efforts” underwriting agreements or similar agreements, as appropriate, including customary provisions
relating to indemnification and contribution, and take such other actions in connection therewith as the Majority Holders shall request in order to expedite or facilitate the disposition of such Securities. 
 (a) If any of the Securities or New Securities, as the case may be, covered by any Shelf Registration Statement are to be sold in an underwritten
offering, the Managing Underwriters shall be selected by the Majority Holders provided that such Managing Underwriters shall be reasonably satisfactory to the Company. 
  

 21 

 (b) No Person may participate in any underwritten offering pursuant to any Shelf Registration Statement,
unless such Person (i) agrees to sell such Person’s Securities or New Securities, as the case may be, on the basis reasonably provided in any underwriting arrangements approved by the Persons entitled hereunder to approve such
arrangements; and (ii) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements. 
 9. No Inconsistent Agreements. The Company has not, as of the date hereof, entered into, nor shall it, on or after the date hereof, enter into,
any agreement with respect to its securities that is inconsistent with the rights granted to the Holders herein or otherwise conflicts with the provisions hereof. 
 10. Amendments and Waivers. The provisions of this Agreement, including the provisions of this sentence, may not be amended, qualified, modified or supplemented, and waivers or consents to departures from the
provisions hereof may not be given, unless the Company has obtained the written consent of the Majority Holders (or, after the consummation of any Registered Exchange Offer in accordance with Section 2 hereof, of New Securities);
provided that, with respect to any matter that directly or indirectly affects the rights of any Purchaser hereunder, the Company shall obtain the written consent of each such Purchaser against which such amendment, qualification, supplement,
waiver or consent is to be effective. Notwithstanding the foregoing (except the foregoing proviso), a waiver or consent to departure from the provisions hereof with respect to a matter that relates exclusively to the rights of Holders whose
Securities or New Securities, as the case may be, are being sold pursuant to a Registration Statement and that does not directly or indirectly affect the rights of other Holders may be given by the Majority Holders, determined on the basis of
Securities or New Securities, as the case may be, being sold rather than registered under such Registration Statement. 
 11. Notices.
All notices and other communications provided for or permitted hereunder shall be made in writing by hand-delivery, first-class mail, telex, telecopier or air courier guaranteeing overnight delivery: 
 (a) if to a Holder, at the most current address given by such holder to the Company in accordance with the provisions of this Section, which address
initially is, with respect to each Holder, the address of such Holder maintained by the Registrar under the Indenture, with copies in like manner to the Representatives. 
 (b) if to the Representatives (for itself or on behalf of any or all of the Purchasers), initially at the address set forth in the Purchase Agreement; and 
  

 22

and enforceability of any such provision in every other respect and of the remaining provisions hereof shall not be in any way impaired or affected thereby, it being intended that all of the rights and privileges of the parties shall be enforceable
to the fullest extent permitted by law. 
 17. Securities Held by the Company, Etc. Whenever the consent or approval of Holders of a
specified percentage of the principal amount of Securities or New Securities is required hereunder, Securities or New Securities, as applicable, held by the Company or its Affiliates (other than subsequent Holders of Securities or New Securities if
such subsequent Holders are deemed to be Affiliates solely by reason of their holdings of such Securities or New Securities) shall not be counted in determining whether such consent or approval was given by the Holders of such required percentage.

 ANNEX A 
 Each Broker-Dealer that receives New Securities for its own account pursuant to the Registered Exchange Offer must acknowledge that it will deliver a prospectus in connection with any resale of such New Securities.
The Letter of Transmittal states that by so acknowledging and by delivering a prospectus, a Broker-Dealer will not be deemed to admit that it is an “underwriter” within the meaning of the Act. This Prospectus, as it may be amended or
supplemented from time to time, may be used by a Broker-Dealer in connection with resales of New Securities received in exchange for Securities where such Securities were acquired by such Broker-Dealer as a result of market-making activities or
other trading activities. The Company has agreed that, starting on the Expiration Date (as defined herein) and ending on the close of business 180 days after the Expiration Date, it will make this Prospectus available to any Broker-Dealer for use in
connection with any such resale. See “Plan of Distribution”. 

 ANNEX B 
 Each Broker-Dealer that receives New Securities for its own account in exchange for Securities, where such Securities were acquired by such Broker-Dealer as a result of market-making activities or other trading
activities, must acknowledge that it will deliver a prospectus in connection with any resale of such New Securities. See “Plan of Distribution”. 

 ANNEX C 
 PLAN OF DISTRIBUTION 
 Each Broker-Dealer that receives New Securities for its own account pursuant
to the Registered Exchange Offer must acknowledge that it will deliver a prospectus in connection with any resale of such New Securities. This Prospectus, as it may be amended or supplemented from time to time, may be used by a Broker-Dealer in
connection with resales of New Securities received in exchange for Securities where such Securities were acquired as a result of market-making activities or other trading activities. The Company has agreed that, starting on the Expiration Date and
ending on the close of business 180 days after the Expiration Date, it will make this Prospectus, as amended or supplemented, available to any Broker-Dealer for use in connection with any such resale. In addition, until the date that is 180 days
from Issue Date, all dealers effecting transactions in the New Securities may be required to deliver a prospectus. 
 The Company will not
receive any proceeds from any sale of New Securities by brokers-dealers. New Securities received by Broker-Dealers for their own account pursuant to the Registered Exchange Offer may be sold from time to time in one or more transactions in the
over-the-counter market, in negotiated transactions, through the writing of options on the New Securities or a combination of such methods of resale, at market prices prevailing at the time of resale, at prices related to such prevailing market
prices or negotiated prices. Any such resale may be made directly to purchasers or to or through brokers or dealers who may receive compensation in the form of commissions or concessions from any such Broker-Dealer and/or the purchasers of any such
New Securities. Any Broker-Dealer that resells New Securities that were received by it for its own account pursuant to the Registered Exchange Offer and any broker or dealer that participates in a distribution of such New Securities may be deemed to
be an “underwriter” within the meaning of the Act and any profit of any such resale of New Securities and any commissions or concessions received by any such Persons may be deemed to be underwriting compensation under the Act. The Letter
of Transmittal states that by acknowledging that it will deliver and by delivering a prospectus, a Broker-Dealer will not be deemed to admit that it is an “underwriter” within the meaning of the Act. 
 For a period of 180 days after the Expiration Date, the Company will promptly send additional copies of this Prospectus and any amendment or supplement
to this Prospectus to any Broker-Dealer that requests such documents in the Letter of Transmittal. The Company has agreed to pay all expenses incident to the Registered Exchange Offer (including the expenses of one counsel for the holder of the
Securities) other than commissions or concessions of any brokers or dealers and will indemnify the holders of the Securities (including any Broker-Dealers) against certain liabilities, including liabilities under the Act.
