 Each Global Note shall represent such of the outstanding Notes as shall be specified therein and each shall provide that it shall represent the aggregate
principal amount of outstanding Notes from time to time endorsed thereon and that the aggregate principal amount of outstanding Notes represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges,
redemptions, repurchases and transfers of interests. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the aggregate principal amount of outstanding Notes represented thereby shall be made by the Trustee or the
Custodian, at the direction of the Trustee, in accordance with instructions given by the Holder thereof as required by Section 2.06 hereof. 
 (c) Euroclear and Clearstream Procedures Applicable. The provisions of the “Operating Procedures of the Euroclear System” and “Terms and Conditions Governing Use of Euroclear” and the “General Terms and

Euroclear or Clearstream. 
 (d) Rule 144A and Regulation S Global Notes. Upon their original issuance, Rule 144A Notes shall be
issued in the form of one or more Global Notes registered in the name of the Depositary or its nominee and deposited with the Trustee, as Custodian for the Depositary, for credit by the Depositary to the respective accounts of beneficial owners of
the Notes represented thereby (or such other accounts as they may direct). Such Global Notes, together with their Successor Notes which are Global Notes other than the Regulation S Global Notes, are collectively herein called the “Rule 144A
Global Note.” 
 Upon their original issuance, Regulation S Notes shall be issued in the form of one or more Global Notes registered in
the name of the Depositary, or its nominee and deposited with the Trustee, as Custodian for the Depositary, for credit to the respective accounts of the beneficial owners of the Notes represented thereby (or such other accounts as they 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 $500 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 entitled to receive, 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 

  

 20 








 
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 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 

  

 21 








 
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. 
 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 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 



  

 22 









	 	 
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 (v) 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 (v) below,
shall reduce the principal amount of the Rule 144A Global Note and increase the principal amount of the Regulation S Global Note by such specified principal amount. 

  

	 	(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 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. 

  

 23 








 (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

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 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

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,

 28

 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. 
  

 29 








 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. 
  

 30 








 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, 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. 
 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); 
  

 31 








 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.

	 	(2)	if the Notes are not listed on any national securities exchange, on a pro rata basis (subject to the procedures of DTC) or, to the extent a pro rata basis is not permitted, by lot
or in such other manner as the Trustee deems fair and appropriate. 

 No Notes of $2,000 of principal amount or less will be
redeemed in part. Except as provided in the preceding sentence, provisions of this Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption.

	 	(8)	the paragraph of the Notes and/or Section of this Indenture pursuant to which the Notes called for redemption are being redeemed; and 

  

	 	(9)	that no representation is made as to the correctness or accuracy of the CUSIP and ISIN (if applicable) numbers, if any, listed in such notice or printed on the Notes.


 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 Trustee give such notice and setting forth the information to be stated in such notice as provided in the preceding paragraph.

 If the Company complies with the provisions of the preceding paragraph, on and after the redemption date,
interest and Additional Interest, if any, on 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. 
 Section 3.07. Optional Redemption. 
 (a) The Notes are 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 for such notes, 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 optional redemption date is on or after an interest record date and on or before the related interest payment date, the
accrued and unpaid interest, if any, will be paid to the person in whose name the note is registered at the close of business on such record date.

give prompt written notice to the Trustee of the location, and 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.

 (iii) to transmit by mail to the Holders of the Notes within 30 days after the filing thereof with the Trustee, in the manner and to the
extent provided in Section 4.07, such summaries of any information, documents and reports required to be filed by the Company pursuant to subsections (a) and (b) of this Section 4.03 as may be required to be transmitted to such
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). 
  

 36 








 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). 

  

	 	(2)	The Company shall, so long as any of the Notes are outstanding, deliver to the Trustee, forthwith upon any Officer becoming aware of any Default or Event of Default, an
Officers’ Certificate specifying such Default or Event of Default and what action the Company is taking or proposes to take with respect thereto. 

 Section 4.05. Taxes. 
 The Company shall pay or discharge or cause to be paid or discharged, and
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. 
 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)); 

  

 37 









	 	(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; 

  

	 	(5)	obligations under Interest Rate Agreements, Commodity Agreements and Currency Agreements not for speculative purposes; 

  

	 	(6)	the Guarantee of Indebtedness of a Subsidiary of the Company that was permitted to be incurred by another provision of this Indenture; 

  

	 	(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 



  

 38 









	 	 
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. 
 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). 
  

 39 








 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; 
 (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, 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. 
  

 40 








 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.

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

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.

  

 43 








 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 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, 

  

 44 








 
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 

  

	 	(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. 
  

 45 








 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. 
 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. 
  

 46 








 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. 
 ARTICLE 7

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

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

shall examine the certificates and opinions required to be furnished to the Trustee hereunder to determine whether or not they conform to the requirements of this Indenture.

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

  

 47 









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

 Section 7.03. Individual Rights of Trustee. 
 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 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 or any money paid to the Company or upon the Company’s direction under any provision of this Indenture, it shall not be responsible for the use or application of any money
received by any Paying Agent other than the Trustee, and it shall not be responsible for any statement or recital herein or any statement in the Notes or any other document in connection with the sale of the Notes or pursuant to this Indenture other
than its certificate of authentication. 
 Section 7.05. Notice of Defaults. 
 If a Default or Event of Default occurs and is continuing and if it is actually known to a Responsible Officer of the Trustee, the Trustee shall 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. 
 Section 7.06. Reports by Trustee to Holders of the Notes. 
 Within 60 days after each May 15 beginning with the May 15 following the Issue Date, and for so long as Notes remain outstanding, the Trustee shall mail to the Holders of the Notes a brief report dated as of
such reporting date that complies with TIA § 313(a) (but if no event 

  

 49 








 
described in TIA § 313(a) has occurred within the twelve months preceding the reporting date, no report need be transmitted). The Trustee also shall
comply with TIA § 313(b). The Trustee shall also transmit by mail all reports as required by TIA § 313(c). 
 A copy of each report
at the time of its mailing to the Holders of Notes shall be mailed to the Company and filed with the SEC and each stock exchange on which the Notes are listed in accordance with TIA § 313(d). The Company shall promptly notify the Trustee when
the Notes are listed on any stock exchange or delisted therefrom. 
 Section 7.07. Compensation and Indemnity.

defending itself against any claim (whether asserted by the Company or any Holder or any other person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, 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. 
 To secure the Company’s payment obligations in this Section 7.07, the Trustee shall have a Lien prior to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal and interest
on particular Notes. Such Lien shall survive the satisfaction and discharge of this Indenture. 
 When the Trustee incurs expenses or renders
services after an Event of Default specified in Section 6.01(7) or (8) hereof occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of
administration under any Bankruptcy Law.

 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.

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

 Section 8.01. Option to Effect Legal Defeasance or Covenant Defeasance. 
 The Company may, at the option of its Board of

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 

  

 52 








 
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; 

  

	 	(2)	the Company’s obligations with respect to such Notes under Article 2 and Section 4.02 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.

times as would have been the case if such Legal Defeasance had not occurred;

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 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; 

  

 56 









	 	(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 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 

  

 57 









	 	(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 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; 

  

 58 









	 	(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; 

  

	 	(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.

  

 59 








 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 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. 
  

 60 








 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.

	 	(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

need not be segregated from other funds except to the extent required by law.

 7.000% Senior Notes Due 2017 
 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 7.000% per annum from October 1, 2007 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 April 15 and October 15 of each year commencing on April 15, 2008, 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 April 1 or October 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 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 October 1, 2007 (the “Indenture”) between the Company and
the Trustee. The terms of the Notes include 

  

 A-6 








 
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 $250 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. 
 15. Authentication. This Note shall
not be valid until authenticated by the manual signature of the Trustee or an authenticating agent. 
 16. Abbreviations. Customary

of Notes under the Indenture, Holders shall have all the rights set forth in the Registration Rights Agreement dated as of October 1, 2007, among the Company and the other parties named on the signature pages thereof.

has caused CUSIP and ISIN numbers to be printed on the Notes and the Trustee may use CUSIP and ISIN numbers in notices of redemption as a convenience to Holders. No representation is made as to the accuracy of such numbers either as printed on the
