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 $600.0 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

  

 19 








 
shall authenticate and deliver such Notes. In authenticating such Exchange Notes, and accepting the additional responsibilities under this Indenture in relation to such Notes, the Trustee shall
be provided with, and (subject to Section 7.01) shall be fully protected in relying upon, an Opinion of Counsel stating, 
  

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

  

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

 The Trustee may appoint an authenticating agent acceptable to the Company to authenticate Notes. An authenticating agent may authenticate
Notes whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as an Agent to deal with Holders or an Affiliate of the
Company. 
 Section 2.03. Registrar and Paying Agent. 
 The Company shall maintain an office or agency where Notes may be presented for registration of transfer or for exchange
(“Registrar”) and an office or agency where Notes may be presented for payment (“Paying Agent”). The Registrar shall keep a register of the Notes and of their transfer and exchange. The Company may appoint one or
more co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrar and the term “Paying Agent” includes any additional paying agent. The Company may change any Paying Agent or Registrar
without notice to any Holder. The Company shall promptly notify the Trustee in writing of the name and address of any Agent not a party to this Indenture. If the Company fails to appoint or maintain another entity as Registrar or Paying Agent, the
Trustee shall act as such. The Company or any of its Subsidiaries may act as Paying Agent or Registrar. 
 The Company initially
appoints The Depository Trust Company (“DTC”) to act as Depositary with respect to the Global Notes. 
 The
Company initially appoints the Trustee to act as the Registrar and Paying Agent and to act as Custodian with respect to the Global Notes. 
 Section 2.04. Paying Agent to Hold Money in Trust. 
 The Company shall
require each Paying Agent other than the Trustee to agree in writing that the Paying Agent will hold in trust for the benefit of the Holders or the Trustee all money held by the Paying Agent for the payment of principal of, or premium, if any, or
interest on the Notes, and will notify the Trustee of any default by the Company in making any such payment. While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Company at any time
may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the Company or a Subsidiary) shall have no further liability for the money. If the Company or a

  

 20 








 
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 90 days after the date of such notice from the Depositary, (ii) the Company in its sole discretion determines that the Global Notes (in whole but
not in part) should be exchanged for Definitive Notes and delivers a written notice to such effect to the Trustee, or (iii) an Event of Default has occurred and is continuing and the Registrar has received a request from the Depositary. Upon
the occurrence of any of the preceding events in (i), (ii) or (iii) above, Definitive Notes shall be issued in such names as the Depositary shall instruct the Trustee. The owner of a beneficial interest in a Global Note will be entitled to
receive a Definitive Note in exchange for such interest if an Event of Default has occurred and is continuing. Global Notes also may be exchanged or replaced, in whole or in part, as provided in Sections 2.07 and 2.10 hereof. Every Note
authenticated and delivered in exchange for, or in lieu of, a Global Note or any portion thereof, pursuant to this Section 2.06, or Section 2.07 or 2.10 hereof, shall be authenticated and delivered in the form of, and shall be, a Global
Note. A Global Note may not be exchanged for another Note other than as provided in this Section 2.06(a); provided, however, that beneficial interests in a Global Note may be transferred and exchanged as provided in Section 2.06(b),
(c) or (f) hereof and a Global Note may be exchanged for another Global Note as provided in Section 2.06(f) hereof. 
 In the event that Definitive Notes are not issued to each holder of a beneficial interest in a Global Note promptly after the Registrar has received a request from the Holder of a Global Note to issue such Definitive Notes, the Company
expressly acknowledges, with respect to the right of any Holder to pursue a remedy pursuant to Section 6.06 or 6.07 hereof, the right of any beneficial holder of Notes to pursue such remedy with respect to the portion of the Global Note that
represents such beneficial holder’s Notes as if such Definitive Notes had been issued. 
  

 21 








 (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 transferred or exchanged and (2) instructions given by the Depositary to the Registrar containing
information regarding the Person in whose name such Definitive Note shall be registered to effect the transfer or exchange referred to in (1) above. Upon satisfaction of all of the requirements for transfer or exchange of beneficial interests
in Global Notes contained in this Indenture and the Notes or otherwise applicable under the Securities Act, the Trustee shall adjust the principal amount of the relevant Global Note(s) pursuant to Section 2.06(g) hereof.


  

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



  

 22 









	 	 
interest in the Regulation S Global Note in a specified principal amount be credited to a specified Participant’s account and that a beneficial interest in the Rule 144A Global Note in an
equal principal amount be debited from another specified Participant’s account and (B) a certificate in the form of Exhibit B hereto, satisfactory to the Trustee and duly executed by the owner of such beneficial interest in the Rule 144A
Global Note or his attorney duly authorized in writing, then the Trustee, as Registrar but subject to clause (iv) below, 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. 

 (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

  

 23 








 
Definitive Notes duly endorsed or accompanied by a written instruction of transfer in form satisfactory to the Registrar duly executed by such Holder or by its attorney, duly authorized in
writing, the Registrar shall register the transfer or exchange of Definitive Notes and effect the transfer or exchange through the Depositary, in accordance with the provisions of this Indenture and the Applicable Procedures. The Trustee shall
cancel the Definitive Note and cause the aggregate principal amount of the applicable Global Note to be increased accordingly pursuant to the terms of this Indenture and the Applicable Procedures. If the Definitive Note to be transferred in whole or
in part is a Restricted Note, or is a Regulation S Note and the transfer is to occur during the Restricted Period therefor, then the Trustee shall have received (A) a certificate substantially in the form of Exhibit C hereto, satisfactory to
the Trustee and duly executed by the transferor Holder or his attorney duly authorized in writing, in which case the transferee Holder shall take delivery in the form of a beneficial interest in the Restricted Global Note, or (B) a certificate
substantially in the form of Exhibit B hereto, satisfactory to the Trustee and duly executed by the transferor Holder or his attorney duly authorized in writing, in which case the transferee Holder shall take delivery in the form of a beneficial
interest in the Regulation S Global Note (subject in every case to Section 2.06(f)). 
 (e) Transfer and Exchange of
Definitive Notes for Definitive Notes. Upon request by a Holder of Definitive Notes and such requesting Holder’s presenting or surrendering to the Registrar the Definitive Notes duly endorsed or accompanied by a written instruction of
transfer in form satisfactory to the Registrar duly executed by such Holder or by its attorney, duly authorized in writing, the Registrar shall register the transfer or exchange of Definitive Notes; provided that, if the Note to be
transferred in whole or in part is a Restricted Note, or is a Regulation S Note and the transfer is to occur during the Restricted Period therefor, then the Trustee shall have received (A) a certificate substantially in the form of Exhibit C

	 	(3)	Registered Notes shall not bear a Securities Act Legend; 

  

	 	(4)	at any time after a Note may be freely transferred without registration under the Securities Act or without being subject to transfer restrictions pursuant to the

deliver such new Note as provided in this Article 2; and 

  

	 	(7)	 notwithstanding the foregoing provisions of this clause (iv) of Section 2.06(f), a Successor Note of a Note that does not bear a particular

but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or similar governmental charge payable upon exchange or transfer
pursuant to Sections 2.10, 3.07, 4.09 and 9.06 hereof). 

  

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

  

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

  

	 	(v)	 The Company shall not be required (A) to issue, to register the transfer of or to exchange any Notes during a period beginning at the opening of



  

 28 









	 	 
business 15 days before the date of any selection of Notes for redemption under Section 3.02 hereof and ending at the close of business on the day of selection, (B) to register the
transfer of or to exchange any Note (i) selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part or (ii) tendered for repurchase or (C) to register the transfer of or to exchange
any Notes during a period beginning at the opening of business 15 days before any Regular Record Date and ending at the close of business on such Regular Record Date. 


  

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

	 	(vii)	The Trustee shall authenticate Global Notes and Definitive Notes in accordance with the provisions of Section 2.02 hereof. 

  

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

 (i) Applicable Procedures for Delegending.

  

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

  

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

  

 29 









	 	(2)	notify Holders of the Notes that the Restricted Notes Legend has been removed or deemed removed; and 

  

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

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

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

 Section 2.07. Replacement Notes. 
 If any mutilated Note is surrendered to the Trustee or the Company and the Trustee receives evidence to its satisfaction of the destruction, loss or theft of any Note, the Company shall issue and the
Trustee, upon receipt of an Authentication Order, shall authenticate a replacement Note if the Trustee’s requirements are met. If required by the Trustee or the Company, an indemnity bond must be supplied by the Holder that is sufficient in the
judgment of the Trustee and the Company to protect the Company, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Company may charge for its expenses in replacing a Note.

  

 30 








 Every replacement Note is an additional obligation of the Company and shall be entitled to
all of the benefits of this Indenture equally and proportionately with all other Notes duly issued hereunder. 
 Section 2.08. Outstanding Notes. 
 The Notes outstanding at any time are all the Notes authenticated by
the Trustee except for those canceled by it, those delivered to it for cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described in this Section as not
outstanding. Except as set forth in Section 2.09 hereof, a Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note. 
 If a Note is replaced pursuant to Section 2.07 hereof, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a bona fide purchaser.

 If the principal amount of any Note is considered paid under Section 4.01 hereof, it ceases to be outstanding and
interest on it ceases to accrue. 
 If the Paying Agent (other than the Company, a Subsidiary or an Affiliate of any thereof)
holds, on a redemption date or maturity date, money sufficient to pay Notes payable on that date, then on and after that date such Notes shall be deemed to be no longer outstanding and shall cease to accrue interest. 
 Section 2.09. Treasury Notes. 
 In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Company, or by any Person directly or indirectly
controlling or controlled by or under direct or indirect common control with the Company, shall be considered as though not outstanding, except that for the purposes of determining whether the Trustee shall be protected in relying on any such
direction, waiver or consent, only Notes that the Trustee knows are so owned shall be so disregarded. 
 Section 2.10.
Temporary Notes. 
 Until certificates representing Notes are ready for delivery, the Company may prepare and the
Trustee, upon receipt of an Authentication Order, shall authenticate temporary Notes. Temporary Notes shall be substantially in the form of certificated Notes but may have variations that the Company considers appropriate for temporary Notes and as
shall be reasonably acceptable to the Trustee. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate definitive Notes in exchange for temporary Notes. 
 Holders of temporary Notes shall be entitled to all of the benefits of this Indenture. 
  

 31 








 Section 2.11. Cancellation. 
 The Company at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent shall forward to the Trustee any
Notes surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else shall cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and shall dispose of such
cancelled Notes in its customary manner in accordance with prudent business practices. The Company may not issue new Notes to replace Notes that it has paid or that have been delivered to the Trustee for cancellation except as expressly permitted
pursuant to this Indenture. 
 Section 2.12. Defaulted Interest. 
 If the Company defaults in a payment of interest on the Notes, it shall pay the defaulted interest in any lawful manner, plus, to the extent
lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, in each case at the rate provided in the Notes and in Section 4.01 hereof. The Company shall notify the Trustee in writing
of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment. The Company shall fix or cause to be fixed each such special record date and payment date, provided that no such special record date
shall be less than 10 days prior to the related payment date for such defaulted interest. At least 15 days before the special record date, the Company (or, upon the written request of the Company and provision of the notice information to the
Trustee, the Trustee in the name and at the expense of the Company) shall mail or cause to be mailed to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid. 
 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; 
  


 32 








 (ii) may have a different amount of interest payable on the first Interest Payment Date
after issuance than is payable on other Notes; and 
 (iii) may have terms specified in the Additional Note Board Resolution or
Additional Note Supplemental Indenture for such Additional Notes making appropriate adjustments to this Article II and Exhibit A (and related definitions) applicable to such Additional Notes in order to conform to and ensure compliance with the
Securities Act (or other applicable securities laws) and any registration rights or similar agreement applicable to such Additional Notes, which are not adverse in any material respect to the Holder of any Notes (other than such Additional Notes);

 provided, that no adjustment pursuant to this Section 2.14 shall cause such Additional Notes to constitute, as determined
pursuant to an Opinion of Counsel, a different class of securities than the Original Notes for U.S. federal income tax purposes except for Additional Notes that have a separate CUSIP and/or ISIN number from the Notes pending performance by the
Company of its obligations under the Registration Rights Agreement. 
 ARTICLE 3 
 REDEMPTION AND PREPAYMENT

redemption date, (2) the principal amount of Notes to be redeemed and (3) the redemption price (expressed as a percentage of the principal amount). 
 Section 3.02. Selection of Notes to Be Redeemed.

	 	(1)	if the Notes are listed on any national securities exchange, in compliance with the requirements of the principal national securities exchange on which the Notes are
listed; or 

  

	 	(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. 
 Notes called for redemption become due on the date fixed for redemption. 
  

 33 








 Section 3.03. Notice of Redemption. 
 At least 30 days but not more than 60 days before a redemption date, the Company shall mail or cause to be mailed, by first class mail, a
notice of redemption 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 a defeasance of the
Notes or a satisfaction and discharge of this Indenture. Notices of redemption may not be conditional. 
 The notice shall
identify the Notes to be redeemed and shall state: 
  

	 	(1)	the CUSIP and ISIN (if applicable) numbers; 

  

	 	(2)	the redemption date;

	 	(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. 
  

 34 








 Section 3.04. Effect of Notice of Redemption. 
 Once notice of redemption is mailed in accordance with Section 3.03 hereof, Notes called for redemption become irrevocably due and
payable on the redemption date at the redemption price. 
 Section 3.05. Deposit of Redemption Price. 
 Prior to 10:00 a.m., Eastern Time, on a redemption date, the Company shall deposit with the Trustee or with the Paying Agent money
sufficient to pay the redemption price of and accrued interest and Additional Interest, if any, on all Notes to be redeemed on that date. The Trustee or the Paying Agent shall promptly return to the Company any money deposited with the Trustee or
the Paying Agent by the Company in excess of the amounts necessary to pay the redemption price of and accrued interest and Additional Interest, if any, on all Notes to be redeemed. 
 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 35 basis points 

  

 35 








 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. 
 (b) Any redemption pursuant to this Section 3.07 shall be made pursuant to the provisions of Section 3.01 through 3.06 hereof.

 Section 3.08. Mandatory Redemption. 
 The Company shall not be required to make mandatory redemption or sinking fund payments with respect to the Notes. 
 ARTICLE 4 
 COVENANTS 
 Section 4.01. Payment of Notes. 
 The Company shall pay or cause to be paid the principal of, premium, if any, and interest on the Notes on the dates and in the manner
provided in the Notes. Principal, premium, if any, and interest shall be considered paid on the date due if the Paying Agent, if other than the Company or a Subsidiary thereof, holds as of 10:00 a.m., Eastern Time, on the due date money deposited by
the Company in immediately available funds and designated for and sufficient to pay all principal, premium, if any, and interest then due. 
 The Company shall, in accordance with Section 2.12 hereof, pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal at the rate equal to
1% per annum in excess of the then applicable interest rate on the Notes to the extent lawful; 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 period) at the same rate to the extent lawful. 
 Section 4.02. Maintenance of Office or
Agency. 
 The Company shall maintain in the Borough of Manhattan, The City of New York, an office or agency (which may be
an office of the Trustee or an affiliate of the Trustee, Registrar or co-registrar) where Notes may be surrendered for registration of transfer or for exchange and where notices and demands to or upon the Company in respect of the Notes and this
Indenture may be served. The Company shall 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. 
  

 36 








 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. 
 The Company hereby designates the Corporate Trust Office as one such office or agency of the
Company in accordance with Section 2.03 hereof. 
 Section 4.03. Reports. 
 The Company covenants: 
 (i) to file with the Trustee, within 15 days after the Company is required to file the same with the SEC, copies of the annual reports and of the information, documents and other reports (or copies of such portions of any of the foregoing
as the SEC may from time to time by rules and regulations prescribe), if any, which the Company may be required to file with the SEC pursuant to Section 13 or Section 15(d) of the Exchange Act; or, if the Company is not required to file
information, documents or reports pursuant to either of such Sections, then to file with the Trustee and the SEC, in accordance with rules and regulations prescribed from time to time by the SEC, such of the supplementary and periodic information,
documents and reports which may be required pursuant to Section 13 of the Exchange Act, in respect of a debt security listed and registered on a national securities exchange as may be prescribed from time to time in such rules and regulations;

 (ii) to file with the Trustee and the SEC, in accordance with rules and regulations prescribed from time to time by the SEC,
such additional information, documents and reports with respect to compliance by the Company with the conditions and covenants provided for in this Indenture as may be required from time to time by such rules and regulations; and 
 (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 12.02, 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). 
  

 37 








 Section 4.04. Compliance Certificate. 
  

	 	(1)	The Company shall deliver to the Trustee, within 90 days after the end of each fiscal year, an Officers’ Certificate stating that a review of the activities of the
Company and its Subsidiaries during the preceding fiscal year has been made under the supervision of the signing Officers with a view to determining whether the Company has kept, observed, performed and fulfilled its obligations under this
Indenture, and further stating, as to each such Officer signing such certificate, that to the best of his or her knowledge the Company has kept, observed, performed and fulfilled each and every covenant contained in this Indenture and is not in
default in the 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, within 5 days 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. [Reserved] 
 Section 4.08. Limitation on Liens. 
  

 38 








 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 the Indebtedness
secured by Liens (other than Permitted Liens) on the property or assets (which includes Capital Stock) of the Company and its Subsidiaries shall not exceed the Permitted Amount at the time of the incurrence of such Liens (it being understood that
Liens securing Existing SpectraSite Indebtedness shall be deemed to be incurred pursuant to this paragraph). For the avoidance of doubt, “incur” means to create, incur, issue, assume, guarantee or otherwise become directly liable,
contingently or otherwise. 
 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; 

 

 39 








 (b) deposit with the Paying Agent an amount equal to the Change of Control
Payment in respect of all Notes or portions thereof properly tendered; and 
 (c) deliver or cause to be
delivered to the Trustee the Notes so accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions thereof being purchased by the Company. 
 The Paying Agent will promptly mail to each registered Holder of Notes so tendered the Change of Control Payment for such Notes, and the
Trustee will promptly authenticate and mail (at the Company’s expense), or cause to be transferred by book entry, to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided
that each such new Note shall be in a principal amount of $2,000 or an integral multiple of $1,000 thereafter. Any Note so accepted for payment shall cease to accrue interest on and after the Change of Control Payment Date. 
 This Section 4.09 shall be applicable, except as described in this Section 4.09, regardless of whether or not any other provisions
of this Indenture are applicable. 
 Notwithstanding the foregoing, the Company shall not be required to make a Change of
Control Offer upon a Change of Control Triggering Event if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 4.09 applicable to a Change of
Control Offer made by the Company and purchases all Notes properly tendered and not withdrawn under the Change of Control Offer. 
 The Company may make a Change of Control Offer in advance of a Change of Control Triggering Event, and conditional upon the occurrence of such Change of Control Triggering Event, if a definitive agreement is in place for the Change of
Control Triggering Event at the time of making the Change of Control Offer. 
 ARTICLE 5 
 SUCCESSORS 
 Section 5.01. Merger, Consolidation or Sale of Assets. 
 The Company may not consolidate or merge with or
into, or sell, lease or convey all or substantially all of its assets in any one transaction or series of related transactions to any other Person, unless: 
  

	 	(1)	the resulting, surviving or transferee corporation (the “successor”) is either the Company or is a corporation organized under the laws of the United
States, any state or the District of Columbia and expressly assumes by supplemental indenture all of the Company’s obligations under this Indenture and the Notes; and 

  

 40 









	 	(2)	immediately after giving effect to the transaction no Default or Event of Default has occurred and is continuing. 

 Section 5.02. Successor Corporation Substituted. 
 Upon any consolidation or merger, or any sale, assignment, transfer, lease, conveyance or other disposition of all or substantially all of the assets of the Company in accordance with Section 5.01
hereof (except in the case of a lease of all or substantially all of the Company’s assets), the successor corporation formed by such consolidation or into or with which the Company is merged or to which such sale, assignment, transfer, lease,
conveyance or other disposition is made shall succeed to, and be substituted for (so that from and after the date of such consolidation, merger, sale, lease, conveyance or other disposition, the provisions of this Indenture referring to the
“Company” shall refer instead to the successor corporation and not to the Company), and may exercise every right and power of the Company under this Indenture with the same effect as if such successor Person had been named as the Company
herein; provided, however, that the predecessor Company shall not be relieved from the obligation to pay the principal of and interest on the Notes except in the case of a sale of all of the Company’s assets that meets the
requirements of Section 5.01 hereof. 
 ARTICLE 6 
 DEFAULTS AND REMEDIES 
 Section 6.01. Events
of Default. 
 The term “Event of Default” with respect to the Notes, wherever used herein, means any one
of the following events which shall have occurred and be continuing (whatever the reason for such Event of Default), whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any
court or any order, rule or regulation of any administrative or governmental body): 
  

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

  

	 	(2)	failure by the Company to pay principal of or premium, if any, on any Note when due, at maturity, upon any redemption, by declaration or otherwise; or


  

	 	(3)	failure by the Company to comply with any other covenant in this Indenture or the Notes for 90 days after notice that compliance was required; or


  

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

 (a) commences a voluntary case, 
  

 41 








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

 (c) consents to the appointment of a custodian of it or for all or substantially all of its property, 
 (d) makes a general assignment for the benefit of its creditors, or 
 (e) generally is not paying its debts as they become due; or 
  

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

 (a) is for relief against the Company or any of its Significant Subsidiaries in an involuntary case; 
 (b) appoints a custodian of the Company or any of its Significant Subsidiaries or for all or substantially all of the property of the
Company or any of its Significant Subsidiaries; or 
 (c) orders the liquidation of the Company or any of its Significant
Subsidiaries; 
 and the order or decree remains unstayed and in effect for 60 consecutive days. 
 Section 6.02. Acceleration. 
 If an Event of Default described in clauses (1) through (3) of Section 6.01 hereof occurs and is continuing, then, and in each and every such case, either the Trustee or the Holders of not
less than 25% in aggregate principal amount of the Notes then outstanding hereunder by notice in writing to the Company (and to the Trustee if given by Holders), may declare the entire principal of all Notes, and the interest and Additional Interest
accrued thereon, if any, to be due and payable immediately, and upon any such declaration, the same shall become immediately due and payable. 
 If an Event of Default described in clause (4) or (5) 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. 
  


 42 








 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, 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. 
  

 43 








 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;

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


 A Holder of a Note may not use this Indenture to prejudice the rights of another Holder of a Note or to obtain
a preference or priority over another Holder of a Note. 
 Section 6.07. Rights of Holders of Notes to Receive
Payment. 
 Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of
principal of, premium, if any, and interest on the Note, on or after the respective due dates expressed in the Note (including in connection with an offer to purchase), or to bring suit for the enforcement of any such payment on or after such
respective dates, shall not be impaired or affected without the consent of such Holder. 
 Section 6.08. Collection Suit
by Trustee.

 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

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.

 First: to the Trustee, its agents and attorneys for amounts due under Section 7.07
hereof, including payment of all compensation, expense and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection; 
 Second: to Holders of Notes for amounts due and unpaid on the Notes for principal, premium, if any, and interest, ratably, without preference or priority of any kind, according to the amounts due and
payable on the Notes for principal, premium, if any and interest, respectively; and 
 Third: to the Company or to such party as
a court of competent jurisdiction shall direct. 
 The Trustee may fix a record date and payment date for any payment to Holders
of Notes pursuant to this Section 6.10. 
 Section 6.11. Undertaking for Costs. 
 In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or
omitted by it as a Trustee, a court in its discretion may

  

 45 








 
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:

expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, in the case of certificates or opinions specifically required by any provision hereof to be furnished to it, the
Trustee 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. 

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

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

  

	 	(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 pertinent facts; and 

  

 46 









	 	(iii)	the Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to

 (e) No
provision of this Indenture shall require the Trustee to expend or risk its own funds or incur any liability. The Trustee shall be under no obligation to exercise any of its rights and powers under this Indenture at the request of any Holders,

Officers’ Certificate or Opinion of Counsel. The Trustee may consult with counsel of its own selection and the written and oral advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection from
liability in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon. 
 (c) The
Trustee may act through its attorneys and agents and shall not be responsible for the misconduct or negligence of any agent appointed with due care.

 47

Securities and this Indenture. 
 (h) The rights, privileges, protections, immunities and benefits given to the Trustee,
including, without limitation, its rights to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and other Person employed to act hereunder.

 (j) The Trustee may request that the Company deliver a certificate setting forth the names of individuals and/or titles of Officers
authorized at such time to take specified actions pursuant to this Indenture. 
 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. 
  

 48 








 Section 7.06. Reports by Trustee to Holders of the Notes. 
 Within 60 days after each December 15 beginning with the December 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 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. 
 The Company shall pay to the Trustee from time to time reasonable compensation for its acceptance of this Indenture and services hereunder. The Trustee’s compensation shall not be limited by any law
on compensation of a trustee of an express trust. The Company shall reimburse the Trustee promptly upon request for all reasonable disbursements, advances and expenses incurred or made by it in addition to the compensation for its services. Such
expenses shall include the reasonable compensation, disbursements and expenses of the Trustee’s agents and counsel. 
 The
Company shall fully indemnify the Trustee against any and all losses, liabilities, claims, damages or expenses (including legal fees and expenses) incurred by it arising out of or in connection with the acceptance or administration of its duties
under this Indenture, including the costs and expenses of enforcing this Indenture against the Company (including this Section 7.07) and 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. 
  

 49 








 When the Trustee incurs expenses or renders services after an Event of Default specified in
Section 6.01(4) or (5) 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.

 The provisions of this Section 7.07 shall survive termination of this Indenture. The Trustee shall comply with the
provisions of TIA § 313(b)(2) to the extent applicable. 
 Section 7.08. Replacement of Trustee. 
 A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor Trustee’s
acceptance of appointment as provided in this Section. 
 The Trustee may resign in writing at any time and be discharged from
the trust hereby created by so notifying the Company. The Holders of a majority in principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and the Company in writing. The Company may remove the Trustee if:

  

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

  

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

  

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

  

	 	(d)	the Trustee becomes incapable of acting. 

 If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company shall promptly appoint a successor Trustee. Within one year after the successor Trustee
takes office, the Holders of a majority in principal amount of the then outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Company. 
 If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the
Company, or the Holders of at least 10% in principal amount of the then outstanding Notes may petition at the expense of the Company any court of competent jurisdiction for the appointment of a successor Trustee. 
 If the Trustee, after written request by any Holder who has been a Holder for at least six months, fails to comply with Section 7.10,
such Holder may petition any court of competent jurisdiction for the removal of the Trustee and 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. 
  

 50 








 Section 7.09. Successor Trustee by Merger, etc. 
 If the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to, another
corporation, the successor corporation without any further act shall be the successor Trustee. 
 Section 7.10.
Eligibility; Disqualification. 
 There shall at all times be a Trustee hereunder that is a corporation organized and
doing business under the laws of the United States of America or of any state thereof that is authorized under such laws to exercise corporate trustee power, that is subject to supervision or examination by federal or state authorities and that has
a combined capital and surplus of at least $75.0 million as set forth in its most recent published annual report of condition. 
 This Indenture shall always have a Trustee who satisfies the requirements of TIA § 310(a)(1), (2) and (5). The Trustee is subject to TIA § 310(b). For purposes of TIA §310(b)(1)(C)(i), the indentures relating to the
Convertible Notes and the Outstanding Notes are hereby specifically described. 
 Section 7.11. Preferential Collection
of Claims Against Company. 
 The Trustee is subject to TIA § 311(a), excluding any creditor relationship listed in TIA
§ 311(b). A Trustee who has resigned or been removed shall be subject to TIA § 311(a) to the extent indicated therein. 
 Section 7.12. Trustee’s Application for Instructions from the Company. 
 Any application by the
Trustee for written instructions from the Company may, at the option of the Trustee, set forth in writing any action proposed to be taken or omitted by the Trustee under this Indenture and the date on and/or after which such action shall be taken or
such omission shall be effective. The Trustee shall not be liable for any action taken by, or omission of, the Trustee in accordance with a proposal included in such application on or after the date specified in such application (which date shall
not be less than three Business Days after the date any Officer of the Company actually receives such application, unless any such Officer shall have consented in writing to any earlier date) unless prior to taking any such action (or the effective
date in the case of an omission), the Trustee shall have received written instructions in response to such application specifying the action to be taken or omitted.

 ARTICLE 8 
 LEGAL DEFEASANCE AND COVENANT DEFEASANCE 
 Section 8.01. Option to Effect Legal Defeasance or Covenant Defeasance. 
 The Company may, at the option
of its Board of Directors evidenced by a resolution set forth in an Officers’ Certificate, at any time, elect to have either Section 8.02 or 8.03 hereof be applied to all outstanding Notes upon compliance with the conditions set forth
below in this Article 8. 
 Section 8.02. Legal Defeasance and Discharge. 
 Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.02, the Company shall,
subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to have been discharged from its obligations with respect to all outstanding Notes on the date the conditions set forth below are satisfied (hereinafter,
“Legal Defeasance”). For this purpose, Legal Defeasance means that the Company shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes, which shall thereafter be deemed to be
“outstanding” only for the purposes of Section 8.05 hereof and the other Sections of this Indenture referred to in (1) and (2) below, and to have satisfied all its other obligations under such Notes and this Indenture (and
the Trustee, on demand of and at the expense of the Company, shall execute proper instruments provided to it acknowledging the same), except for the following provisions which shall survive until otherwise terminated or discharged hereunder:

  

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

  

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

  

	 	(3)	the rights, powers, trusts, duties and immunities of the Trustee and the Company’s obligations in connection therewith; and 

  

	 	(4)	this Article 8. 

 Subject to
compliance with this Article 8, the Company may exercise its option under this Section 8.02 notwithstanding the prior exercise of its option under Section 8.03 hereof. 
 Section 8.03. Covenant Defeasance. 
 Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Company shall, subject to the satisfaction of the conditions set forth in
Section 8.04 hereof, be released from its obligations under the covenants contained in Sections 4.08 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).

  

 52 








 
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(4) and 6.01(5) hereof shall not
constitute Events of Default. 
 Section 8.04. Conditions to Legal or Covenant Defeasance. 
 The following shall be the conditions to the application of either Section 8.02 or 8.03 hereof to the outstanding Notes: 
 In order to exercise either Legal Defeasance or Covenant Defeasance: 
  

	 	(1)	the Company must irrevocably deposit or cause to be deposited with the Trustee, in trust, for the benefit of the Holders, cash in United States dollars, non-callable
Government Securities, or a combination thereof, in amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the principal of, premium, if any, interest and Additional Interest, if any,
on the outstanding Notes on the stated date for payment thereof or on the applicable redemption date, as the case may be, and the Company shall specify whether the Notes are being defeased to maturity or to a particular redemption date;


  

	 	(2)	in the case of an election under Section 8.02 hereof, the Company has delivered to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee
confirming that: 

  

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

  

	 	(b)	since the Issue Date, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel
will confirm that, the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner
and at the same times as would have been the case if such Legal Defeasance had not occurred; 

  

	 	(3)	 in the case of an election under Section 8.03 hereof, the Company has delivered to the Trustee an Opinion of Counsel reasonably acceptable to the
Trustee confirming that the Holders of the outstanding Notes will not



  

 53 









	 	 
recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the
same times as would have been the case if such Covenant Defeasance had not occurred; 


  

	 	(4)	no Default or Event of Default has occurred and is continuing on the date of such deposit (other than a Default or Event of Default resulting from the borrowing of
funds to be applied to such deposit); 

  

	 	(5)	such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under, any material agreement or instrument (other
than this Indenture) to which the Company or any of its Subsidiaries is a party or by which the Company or any of its Subsidiaries is bound; 

  

	 	(6)	the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that on the 91st day following the deposit, the trust funds will not be subject to
the effect of any applicable bankruptcy, insolvency, reorganization or similar laws affecting creditors’ rights generally; 

  

	 	(7)	the Company shall have delivered to the Trustee an Officers’ Certificate stating that the deposit was not made by the Company with the intent of preferring the
Holders over any other creditors of the Company or with the intent of defeating, hindering, delaying or defrauding any other creditors of the Company or others; and 

  

	 	(8)	the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for or
relating to the Legal Defeasance or the Covenant Defeasance have been complied with. 

 Section 8.05.
Deposited Money and Government Securities to be Held in Trust; Other Miscellaneous Provisions. 
 Subject to
Section 8.06 hereof, all money and non-callable Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.05, the “Trustee”)
pursuant to Section 8.04 hereof in respect of the outstanding Notes shall be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying
Agent (including the Company acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, premium, if any, and interest, but such money need not be segregated
from other funds except to the extent required by law. 
 The Company shall pay and indemnify the Trustee against any tax, fee
or other charge imposed on or assessed against the cash or non-callable Government Securities deposited pursuant to Section 8.04 hereof or the principal and interest received in respect thereof other than any such tax, fee or other charge which
by law is for the account of the Holders of the outstanding Notes. 
  

 54 








 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. 
  

 55 








 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;

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

 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

  

 57 








 
Holders of the Notes; and, subject to Sections 6.04 and 6.07 hereof, any existing Default or Event of Default (other than an uncured Default or Event of Default in the payment of principal,
premium or interest on the Notes, except a payment default resulting from an acceleration that has been rescinded) and compliance with any provision of the Indenture or the Notes may be waived with the consent of the Holders of not less than a
majority in principal amount of the then-outstanding Notes, voting as one class (including, without limitation, consents obtained in connection with a purchase of, or tender or exchange offer for, the Notes); provided, however, that
without the consent of each Holder affected, an amendment or waiver under this Section 9.02 may not (but only with respect to any Notes held by a non-consenting Holder): 
  

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

  

	 	(2)	reduce the principal amount of any Note; 

  

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

  

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

  

	 	(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

  

 58 








 
authorizing the execution of any such supplemental indenture, and upon the filing with the Trustee of evidence of the consent of the Holders of the Notes as aforesaid, the Trustee shall join with
the Company in the execution of such supplemental indenture unless such supplemental indenture affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may at its discretion, but shall
not be obligated to, enter into such supplemental indenture. 
 It shall not be necessary for the consent of the Holders of
Notes under this Section 9.02 to approve the particular form of any proposed supplemental indenture, but it shall be sufficient if such consent shall approve the substance thereof. 
 Promptly after the execution by the Company and the Trustee of any supplemental indenture pursuant to the provisions of this
Section 9.02, the Company (or the Trustee at the request and expense of the Company) shall give notice thereof to the Holders of then outstanding Notes affected thereby, as provided in Section 11.02. Any failure of the Company to give such
notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such supplemental indenture. 
 Section 9.03. Effect of Supplemental Indenture, Amendment or Waiver. 
 Upon the execution of any
supplemental indenture pursuant to the provisions hereof, or any amendment to or waiver of the provisions of the Indenture, this Indenture shall be and shall 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. 
  


 59 








 Section 9.06. Notation on or Exchange of Notes. 
 Notes authenticated and delivered after the execution of any supplemental indenture, amendment or waiver pursuant to the provisions of this
Article 9 may bear a notation in form approved by the Trustee as to any matter provided for by such supplemental indenture or as to any action taken by the Holders of Notes. If the Company or the Trustee shall so determine, new Notes so modified as
to conform, in the opinion of the Trustee and the Company, to any modification of this Indenture contained in any such supplemental indenture may be prepared and executed by the Company, authenticated by the Trustee and delivered in exchange for the
Notes then outstanding. 
 Failure to make the appropriate notation or issue a new Note shall not affect the validity and effect
of such amendment, supplement or waiver. 
 Section 9.07. Trustee to Sign Amendments, etc. 
 The Trustee shall sign any amended or supplemental indenture authorized pursuant to this Article 9 if the amendment or supplement does not
adversely affect the rights, duties, liabilities or immunities of the Trustee. In executing any amended or supplemental indenture, the Trustee shall be provided with and (subject to Section 7.01 hereof) shall be fully protected in relying upon,
in addition to the documents required by Section 12.04 hereof, an Officer’s Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by this Indenture.

 SATISFACTION AND DISCHARGE 
 Section 11.01. Satisfaction and Discharge. 
 This Indenture shall be
discharged and shall cease to be of further effect as to all Notes issued hereunder, when:

	 	(a)	all Notes that have been authenticated, except lost, stolen or destroyed Notes that have been replaced or paid and Notes for whose payment money has been deposited in
trust and thereafter repaid to the Company, have been delivered to the Trustee for cancellation; or 

  

	 	(b)	 all Notes that have not been delivered to the Trustee for cancellation have become due and payable by reason of the mailing of a notice of redemption
or otherwise or will



  

 60 









	 	 
become due and payable within one year and the Company has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders, cash in
U.S. dollars, non-callable Government Securities, or a combination of cash in U.S. dollars and non-callable Government Securities, in amounts as will be sufficient without consideration of any reinvestment of interest, to pay and discharge the
entire indebtedness on the Notes not delivered to the Trustee for cancellation for the principal amount and premium, if any, plus accrued interest and Additional Interest, if any, on all Notes; and 


  

	 	(2)	no Default or Event of Default has occurred and is continuing on the date of the deposit or will occur as a result of the deposit and the deposit will not result in a
breach or violation of, or constitute a default under, any other instrument to which the is a party or by which the Company is bound; 

  

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

  

	 	(4)	the Company has delivered irrevocable instructions to the Trustee under this Indenture to apply the deposited money toward the payment of the Notes at maturity or the
redemption date, as the case may be. 

 In addition, the Company must deliver an Officers’ Certificate to the
Trustee stating that all conditions precedent to satisfaction and discharge have been satisfied. 
 Notwithstanding the
satisfaction and discharge of this Indenture, if money has been deposited with the Trustee pursuant to subclause (b) of clause (1) of this Section, the provisions of Section 11.02 and Section 8.06 shall survive. In addition,
nothing in this Section 11.01 shall be deemed to discharge those provisions of Section 7.07 hereof, that, by their terms, survive the satisfaction and discharge of this Indenture. 
 Section 11.02. Notices. 
 Subject to the provisions of Section 8.06, all money deposited with the Trustee pursuant to Section 11.01 shall be held in trust and applied by it, in accordance with the provisions of the Notes
and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal and premium, if any, and interest
and Additional Interest, if any, for whose payment such money has been deposited with the Trustee; but such money need not be segregated from other funds except to the extent required by law. 
 If the Trustee or Paying Agent is unable to apply any money or Government Securities in accordance with Section 11.01 by reason of any
legal proceeding or by reason of any order or

  

 61 








 
judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s obligations under this Indenture and the Notes shall be
revived and reinstated as though no deposit had occurred pursuant to Section 11.01; provided that if the Company has made any payment of principal of and premium, if any, and interest and Additional Interest, if any, on any Notes because
of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or Government Securities held by the Trustee or Paying Agent.

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 March 15 or September 15 next preceding the Interest Payment Date (each, a “Regular Record Date”), even if such Notes are canceled after such record date and on or before such
Interest Payment Date, except as provided in Section 2.12 of the Indenture with respect to defaulted interest. The Notes will be payable as to principal, premium, if any, and interest and Additional Interest, if any, at the office or agency of
the Paying Agent and Registrar maintained for such purpose within the City and State of New York, or, at the option of the Company, payment of interest and Additional Interest, if any, may be made by check mailed to the Holders at their addresses
set forth in the register of Holders, and provided that payment by wire transfer of immediately available funds will be required with respect to principal of, premium, if any, and interest and Additional Interest, if any, on, all Global Notes
and all other Notes the Holders of which shall have provided wire transfer instructions to the Company or the Paying Agent. Such payment shall be in such coin or currency of the United States of America as at the time of payment is legal tender for
payment of public and private debts. 
 3. Paying Agent and Registrar. Initially, The Bank of New York Mellon Trust
Company, N.A., the Trustee under the Indenture, will act as Paying Agent and Registrar. The Company may change any Paying Agent or Registrar without notice to any Holder. The Company or any of its Subsidiaries may act in any such capacity.

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 $600.0 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 35 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 

  

	 	(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 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. 
  

 A-8 








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