of redemption to November 1, 2014 is less than one year, the weekly average yield on actually traded United States Treasury securities adjusted to a constant maturity of one year shall be used. 
 “Trustee” means the party named as such above until a successor replaces it in accordance with the applicable provisions of
this Supplemental Indenture and thereafter means the successor serving hereunder. 
 “Unrestricted Subsidiary”
means any Subsidiary of the Company that is designated by the Board of Directors as an Unrestricted Subsidiary pursuant to a Board Resolution; but only to the extent that such Subsidiary: 
 (1) is not party to any agreement, contract, arrangement or understanding with the Company or any Restricted Subsidiary of
the Company unless the terms of any such agreement, contract, arrangement or understanding are no less favorable to the Company or such Restricted Subsidiary than those that might be obtained, at the time from Persons who are not Affiliates of the

Certificate certifying that such designation complied with the foregoing conditions and was permitted by Section 4.07. If, at any time, any Unrestricted Subsidiary would fail to meet the foregoing requirements as an Unrestricted Subsidiary, it
shall thereafter cease to be an Unrestricted Subsidiary for purposes of this Indenture and any Indebtedness of that Subsidiary shall be deemed to be incurred by a Restricted Subsidiary of the Company as of such date (and, if such Indebtedness is not
permitted to be incurred as of such date under Section 4.09, the Company shall be in Default of such covenant). Any Subsidiary of an Unrestricted Subsidiary that was properly designated an Unrestricted Subsidiary shall also constitute an

to the nearest one-twelfth) that shall elapse between such date and the making of such payment; by 
 (2) the
then outstanding principal amount of such Indebtedness. 
 “Wholly Owned Restricted Subsidiary” of any Person
means a Restricted Subsidiary of such Person all of the outstanding Capital Stock or other ownership interests of which (other than directors’ qualifying shares) shall at the time be owned by such Person or by one or more Wholly Owned

 ARTICLE 2 
 THE NOTES 
 Section 2.01 Issuance; Form
and Dating. (a) The Notes and the Trustee’s certificate of authentication shall be substantially in the form of Exhibit A, which is hereby incorporated in and expressly made part of this Supplemental Indenture. The Notes may have
notations, legends or endorsements required by law, stock exchange rule, agreements to which the Company is subject, if any, or usage (provided that any such notation, legend or endorsement is in a form acceptable to the Company). 

(b) All of the Notes shall be issued initially in the form of one or more Global Notes, which shall be deposited on behalf of the
purchasers of the Notes represented thereby with the Trustee as Custodian for the depositary, The Depository Trust Company (“DTC”) (such depositary, or any successor thereto, being hereinafter referred to as the
“Depositary”), and registered in the name of its nominee, Cede & Co., duly executed by the Company and authenticated by the Trustee as hereinafter provided. The aggregate principal amount of the each Global Note may from
time to time be increased or decreased by adjustments made on the records of the Custodian as hereinafter provided, subject in each case to compliance with the Applicable Procedures. 
 (c) Each Global Note shall represent such of the outstanding Notes as shall be specified therein and each shall provide that it shall
represent the aggregate amount of outstanding Notes from time to time endorsed thereon and that the aggregate amount of outstanding Notes represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges,
purchases or conversions of such Notes. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the amount of outstanding Notes represented thereby shall be made by the Custodian in accordance with the standing
instructions and procedures existing between the Depositary and the Custodian. 
 (d) Members of, or participants in, the
Depositary (“Agent Members”) shall have no rights under this Supplemental Indenture with respect to any Global Note held on their behalf by the Depositary or under any Global Note, and the Depositary (including, for this purpose,
its nominee) may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner and Holder of such Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall
(1) prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or (2) impair, as between the Depositary and its
Agent Members, the operation of customary practices governing the exercise of the rights of a Holder of any Note. 
 Section 2.02 Execution and Authentication. (a) An Officer shall sign the Notes for the Company by manual or facsimile signature. Typographic and other minor defects in any facsimile signature shall not affect the validity
or enforceability of any Note which has been authenticated and delivered by the Trustee. 
  

 27 

 (b) If an Officer whose signature is on a Note no longer holds that office at the time the
Trustee authenticates the Note, the Note shall be valid nevertheless. 
 (c) A Note shall not be valid until an authorized
signatory of the Trustee manually signs the certificate of authentication on the Note. The signature shall be conclusive evidence that the Note has been authenticated under this Supplemental Indenture. 
 (d) On the date hereof, the Trustee shall authenticate and deliver up to $500,000,000 principal amount of 7.125% Senior Notes due 2019,
which shall be represented by one or more Global Notes. 
 (e) The Trustee may appoint an authenticating agent acceptable to the
Company to authenticate the Notes. Unless limited by the terms of such appointment, an authenticating agent may authenticate Notes whenever the Trustee may do so. Each reference in this Supplemental Indenture to authentication by the Trustee
includes authentication by such agent. An authenticating agent has the same rights as any Registrar, Paying Agent or agent for service of notices and demands. 
 Section 2.03 Registrar and Paying Agent. (a) The Company shall maintain an office or agency where the Notes may be presented for registration of transfer or for exchange (the
“Registrar”), and an office or agency where Notes may be presented for payment (“Paying Agent”). The Trustee shall initially act as the Registrar and Paying Agent. The Registrar shall keep a register of the Notes
and of their transfer and exchange. The Company may appoint one or more co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrar and the term “Paying Agent” includes any additional
paying agent. The Company may change any Paying Agent or Registrar without notice to any Holder. The Company shall notify the Trustee in writing of the name and address of any agent not a party to this Supplemental Indenture. If the Company fails to
appoint or maintain another entity as the Registrar or Paying Agent, the Trustee shall act as such. The Company or any of its Subsidiaries may act as Paying Agent or Registrar. 
 (b) The Company initially appoints the Trustee to act as the Registrar and Paying Agent and to act as Custodian with respect to the Notes.

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

 28 

 (b) The Company shall require each Paying Agent other than the Trustee to agree in writing
that the Paying Agent shall hold in trust for the benefit of the Holders or the Trustee all money held by the Paying Agent for the payment of principal of, or premium, if any, or interest on the Notes, and shall notify the Trustee of any Default by
the Company in making any such payment. While any such Default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Company at any time may require a Paying Agent to pay all money held by it to the
Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the Company or a Subsidiary) shall have no further liability for the money. If the Company or a Subsidiary acts as Paying Agent, it shall segregate and hold in a separate
trust fund for the benefit of the Holders all money held by it as Paying Agent. Upon any bankruptcy or reorganization proceedings relating to the Company, the Trustee shall serve as Paying Agent for the Notes. 
 Section 2.05 Holder Lists. The Trustee shall preserve in as current a form as is reasonably practicable the most recent list
available to it of the names and addresses of Holders and shall otherwise comply with TIA § 312(a). If the Trustee is not the Registrar, the Company shall furnish to the Trustee at least 10 days before each interest payment date and at such
other times as the Trustee may request in writing a list, in such form and as of such date as the Trustee may reasonably require, of the names and addresses of Holders, and the Company shall otherwise comply with TIA § 312(a). 
 Section 2.06 Transfer and Exchange. (a) The Notes shall be issued in registered form and shall be transferable only upon
the surrender of a Note for registration of transfer. When a Note is presented to the Registrar with a request to register a transfer, the Registrar shall register the transfer as requested if the requirements of this Supplemental Indenture are
satisfied. When Notes are presented to the Registrar with a request to exchange them for an equal principal amount of Notes of other denominations, the Registrar shall make the exchange as requested if the requirements of this Supplemental Indenture
are met. To permit registration of transfers and exchanges, the Company shall execute and the Trustee shall authenticate Notes at the Registrar’s request. The Company or the Registrar may require payment by the Holder of a sum sufficient to pay
all taxes, assessments or other governmental charges in connection with any transfer or exchange pursuant to this Section. 
 (b) Prior to the due presentation for registration of transfer of any Note, the Company, the Trustee, the Paying Agent or the Registrar may deem and treat the person in whose name a Note is registered as the absolute owner of such Note for
the purpose of receiving payment of principal of and (subject to the provisions of the Notes with respect to record dates) interest on such Note and for all other purposes whatsoever, whether or not such Note is overdue, and none of the Company, the
Trustee, the Paying Agent or the Registrar shall be affected by notice to the contrary. 
 (c) Neither the Company nor the
Registrar shall be required (a) to issue, register the transfer of, or exchange the Notes for the period beginning at the opening of business 15 days immediately preceding the mailing of a notice of redemption of the Notes selected for
redemption and ending at the close of business on the day of such mailing, or (b) to register the

  

 29 

 
transfer of or exchange the Notes selected, called or being called for redemption as a whole or the portion being redeemed of any such Notes selected, called or being called for redemption in
part. 
 (d) All Notes issued upon any transfer or exchange pursuant to the terms of this Supplemental Indenture shall evidence
the same debt and shall be entitled to the same benefits under this Supplemental Indenture as the Notes surrendered upon such transfer or exchange. 
 Section 2.07 Additional Transfer and Exchange Requirements. (a) Transfer and Exchange of Global Notes. (1) Certificated Notes shall be issued in exchange for interests in the
Global Notes only if (x) the Depositary notifies the Company that it is unwilling or unable to continue as depositary for the Global Notes or if it at any time ceases to be a “clearing agency” registered under the Exchange Act, if so
required by applicable law or regulation, and a successor depositary is not appointed by the Company within 90 days or (y) upon request of a Holder upon an Event of Default or a Default has occurred and is continuing. In either such case, the
Company shall execute, and the Trustee shall, upon receipt of a Company Order and an Officers’ Certificate, authenticate and deliver Certificated Notes in an aggregate principal amount equal to the principal amount of such Global Notes in
exchange therefor. Certificated Notes issued in exchange for beneficial interests in Global Notes shall be registered in such names and shall be in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect
participants or otherwise, shall instruct the Trustee. The Trustee shall deliver or cause to be delivered such Certificated Notes to the persons in whose names such Notes are so registered. Such exchange shall be effected in accordance with the
Applicable Procedures. (2) Notwithstanding any other provisions of the Indenture other than the provisions set forth in this Section 2.07(a)(1), a Global Note may not be transferred as a whole except by the Depositary to a nominee of the
Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. 
 (b) Transfer and Exchange of Certificated Notes. In the event that Certificated Notes are issued in exchange for beneficial interests
in Global Notes in accordance of Section 2.07(a)(1), on or after such event when Certificated Notes are presented by a Holder to a Registrar with a request: (x) to register the transfer of the Certificated Notes to a person who shall take
delivery thereof in the form of Certificated Notes only; or (y) to exchange such Certificated Notes for an equal principal amount of Certificated Notes of other authorized denominations, such Registrar shall register the transfer or make the
exchange as requested if the requirements for such transaction under this Supplemental Indenture are satisfied; provided, however, that the Certificated Notes presented or surrendered for register of transfer or exchange shall be duly
endorsed or accompanied by an assignment form and, if applicable, a transfer certificate each in the form included in Exhibit A, and in a form satisfactory to the Registrar duly executed by the Holder thereof or its attorney duly authorized in
writing. 
  

 30 

 (c) Transfers of Certificated Notes for Beneficial Interest in Global Notes. In the
event that Certificated Notes are issued in exchange for beneficial interests in Global Notes and, thereafter, the events or conditions specified in Section 2.07(a)(1) which required such exchange shall cease to exist, the Company shall mail
notice to the Trustee and to the Holders stating that Holders may exchange Certificated Notes for interests in Global Notes by complying with the procedures set forth in this Supplemental Indenture and briefly describing such procedures and the
events or circumstances requiring that such notice be given. Thereafter, if Certificated Notes are presented by a Holder to a Registrar with a request: (x) to register the transfer of such Certificated Notes to a person who shall take delivery
thereof in the form of a beneficial interest in a Global Note; or (y) to exchange such Certificated Notes for an equal principal amount of beneficial interests in a Global Note, which beneficial interests shall be owned by the Holder
transferring such Certificated Notes, the Registrar shall register the transfer or make the exchange as requested by canceling such Certificated Note and causing, or directing the Custodian to cause, the aggregate principal amount of the applicable
Global Note to be increased accordingly and, if no such Global Note is then outstanding, the Company shall issue and the Trustee shall authenticate and deliver a new Global Note; provided, however, that the Certificated Notes presented
or surrendered for registration of transfer or exchange shall be duly endorsed and accompanied by an assignment form and, if applicable, a transfer certificate each in the form included in Exhibit A, and in a form satisfactory to the Registrar duly
executed by the Holder thereof or its attorney duly authorized in writing; 
 (d) Transfers to the Company. Nothing in
this Indenture or in the Notes shall prohibit the sale or other transfer of any Notes (including beneficial interests in Global Notes) to the Company or any of its Subsidiaries. 
 (e) No Obligation of the Trustee. 
 (i) The Trustee shall have no responsibility or obligation to any beneficial owner of a Global Note, a member of, or a participant in the Depositary or other Person with respect to the accuracy of the
books or records, or the acts or omissions, of the Depositary or its nominee or of any participant or member thereof, with respect to any ownership interest in the Notes or with respect to the delivery to any participant, member, beneficial owner or
other Person (other than the Depositary) of any notice or the payment of any amount, under or with respect to such Notes. All notices and communications to be given to the Holders and all payments to be made to Holders under the Notes shall be given
or made only to or upon the order of the registered Holders (which shall be the Depositary or its nominee in the case of a Global Note). The rights of beneficial owners in any Global Note shall be exercised only through the Depositary subject to the
Applicable Procedures of the Depositary. The Trustee may rely and shall be fully protected in relying upon information furnished by the Depositary with respect to its members, participants and any beneficial owners. 
  

 31 

 (ii) The Trustee shall have no obligation or duty to monitor, determine or
inquire as to compliance with any restrictions on transfer imposed under this Supplemental Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among Depositary participants,
members or beneficial owners in any Global Note) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by, the terms of this Indenture, and
to examine the same to determine substantial compliance as to form with the express requirements hereof. 
 Section 2.08
Mutilated, Destroyed, Lost and Stolen Notes. (a) If any mutilated Note is surrendered to the Trustee, the Company shall execute and the Trustee, upon receipt of a Company Order, shall authenticate and deliver in exchange therefor a new
Note of like tenor and principal amount and bearing a number not contemporaneously outstanding. 
 (b) If there shall be
delivered to the Company and the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Note and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them
harmless, then, in the absence of notice to the Company or the Trustee that such Note has been acquired by a bona fide purchaser, the Company shall execute and the Trustee, upon receipt of a Company Order, shall authenticate and make available for
delivery, in lieu of any such destroyed, lost or stolen Note, a new Note of like tenor and principal amount and bearing a number not contemporaneously outstanding. 
 (c) In case any such mutilated, destroyed, lost or stolen Note has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Note, pay such Note.

 (d) Upon the issuance of any new Note under this Section 2.08, the Company may require the payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith. 
 (e) Every new Note issued pursuant to this Section 2.08 in lieu of any destroyed, lost or stolen Note shall constitute an original
additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Note shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all
other Notes duly issued hereunder. 
 (f) The provisions of this Section 2.08 are exclusive and shall preclude (to the
extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes. 
  

 32 

 Section 2.09 Outstanding Notes. (a) The Notes outstanding at any time are
all the Notes authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and those
described in this Section as not outstanding. 
 (b) If a Note is replaced pursuant to Section 2.08 hereof, it ceases to be
outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a bona fide purchaser. 
 (c)
If the principal amount of any Note is considered paid under Section 4.01 hereof, it ceases to be outstanding and interest on it ceases to accrue. 
 (d) If the Paying Agent (other than the Company, a Subsidiary or an Affiliate of any thereof) holds, on a redemption date or maturity date, money sufficient to pay the Notes payable on that date, then on
and after that date such Notes shall be deemed to be no longer outstanding and shall cease to accrue interest. 
 (e) A Note
does not cease to be outstanding because the Company or an Affiliate holds the Note. 
 Section 2.10 Treasury Notes.
In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Company, or by any Affiliate of the Company, shall be considered as though not outstanding, except
that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes that the Trustee actually knows are so owned shall be so disregarded. 
 Section 2.11 Temporary Notes. Until certificates representing the Notes are ready for delivery, the Company may prepare and the
Trustee, upon receipt of a Company Order, shall authenticate temporary Notes. Temporary Notes shall be substantially in the form of Certificated Notes but may have variations that the Company considers appropriate for temporary Notes and as shall be
reasonably acceptable to the Trustee. Without unreasonable delay, the Company shall prepare and the Trustee, upon receipt of a Company Order, shall authenticate definitive Notes in exchange for temporary Notes. Until so exchanged, temporary Notes
shall have the same rights under this Supplemental Indenture as the definitive Notes. 
 Section 2.12 Cancellation.
The Company at any time may deliver Notes to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee shall cancel all
Notes surrendered for transfer, exchange, payment, replacement or cancellation and shall destroy such canceled Notes (subject to the record retention requirement of the Exchange Act) and deliver a certificate of such destruction to the Company,
unless the Company otherwise directs. The Company may not issue new Notes to replace Notes that it has paid or delivered to the Trustee for cancellation. 
  

 33 

 Section 2.13 Defaulted Interest. If the Company defaults in a payment of
interest on the Notes, it shall pay the defaulted interest, plus, to the extent permitted by law, any interest payable on the defaulted interest, to the persons who are Holders on a subsequent special record date. The Company shall fix the record
date and payment date. At least 30 days before the record date, the Company shall mail to the Trustee and to each Holder of the Notes a notice that states the record date, the payment date and the amount of interest to be paid. The Company may pay
defaulted interest in any other lawful manner. 
 Section 2.14 CUSIP Numbers. The Company in issuing the Notes may
use “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in notices of redemption as a convenience to Holders; provided, however, that any such notice may state that no
representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of a redemption and that reliance may be placed only on the other elements of identification printed on the Notes, and any such
redemption shall not be affected by any defect in or omission of such numbers. 
 Section 2.15 No Sinking Fund. No
sinking fund shall be provided with respect to the Notes. 
 Section 2.16 Issuance of Additional Notes.
(a) After the date hereof, the Company shall be entitled, subject to its compliance with Section 4.09, to issue additional Notes under this Supplemental Indenture, which Notes shall have identical terms as the Notes issued on the date
hereof, other than with respect to the date of issuance and the amount of the issue price. All the Notes issued under this Supplemental Indenture shall be treated as a single class for all purposes of this Supplemental Indenture including waivers,
amendments, redemptions and offers to purchase. 
 (b) With respect to any additional Notes, the Company shall set forth in a
Board Resolution and an Officers’ Certificate, a copy of each which shall be delivered to the Trustee, the following information: 
 (i) the aggregate principal amount of such additional Notes to be authenticated and delivered pursuant to this Supplemental Indenture and the provision of Section 4.09 that the Company is relying on
to issue such additional Notes; and 
 (ii) the issue price, the issue date and the CUSIP number of such
additional Notes; provided, however, that no additional Notes may be issued at a price that would cause such additional Notes to not be fungible for U.S. federal income tax purposes with any other Notes issued under this Supplemental
Indenture.

Notices to Trustee. If the Company desires to redeem all or part of the Notes pursuant to Section 3.07, it shall notify the Trustee of the redemption date and the principal amount of the Notes to be redeemed. The Company shall give the
notice to the Trustee at least 30 but no more that 60 days before the redemption date (or such shorter notice as may be acceptable to the Trustee). 
 Section 3.02 Selection of Notes to Be Redeemed. 
 (a) If less than all
of the Notes are to be redeemed at any time, the Trustee shall select Notes for redemption as follows: 
 (i) if
the Notes are listed on any national securities exchange, in compliance with the requirements of the principal national securities exchange, if any, on which the Notes are listed; or 
 (ii) if the Notes are not listed on any national securities exchange, on a pro rata basis, by lot or by a method that
complies with approved legal and securities exchange requirements, if any, as the Trustee in its sole discretion shall deem fair and appropriate. 
 (b) No Notes of $2,000 of principal amount at maturity or less shall be redeemed in part. Notice of redemption shall be mailed by first class mail at least 30 but not more than 60 days before the
redemption date to each Holder of Notes to be redeemed at its registered address. 
 (c) If any Note is to be redeemed in part
only, the notice of redemption that relates to such Note shall state the portion of the principal amount of that Note to be redeemed. A new Note in principal amount equal to the unredeemed portion of the original Note presented for redemption shall
be issued in the name of the Holder thereof upon cancellation of the original Note. Notes called for redemption become due on the date fixed for redemption. On and after the redemption date, interest ceases to accrue on Notes or portions of them
called for redemption. 
 Section 3.03 Notice of Redemption. 
 (a) At least 30 days but not more than 60 days before a redemption date, the Company shall mail or cause to be mailed a notice of redemption
to each Holder whose Notes are to be redeemed at its registered address. The notice shall identify the Notes to be redeemed and shall state: 
 (i) the redemption date; 
  

 35 

 (ii) the redemption price; 
 (iii) if any Note is being redeemed in part, the portion of the principal amount of such Note to be redeemed and that, after
the redemption date upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion shall be issued upon cancellation of the original Note; 
 (iv) the name and address of the Paying Agent; 
 (v) that Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price; 
 (vi) that, unless the Company defaults in making such redemption payment, interest on the Notes called for redemption ceases
to accrue on and after the redemption date; 
 (vii) the paragraph of the Notes and/or provision of this
Indenture pursuant to which the Notes called for redemption are being redeemed; and 
 (viii) that no
representation is made as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the Notes. 
 (b) At the Company’s request, the Trustee shall give the notice of redemption in the Company’s name and at its expense; provided, however, that the Company shall have delivered to the Trustee, at least 45 days 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 Section 3.03(a) paragraph. 
 Section 3.04 Effect of Notice of Redemption. Once notice of redemption is mailed in accordance with Section 3.03 hereof, the
Notes called for redemption become irrevocably due and payable on the redemption date at the redemption price. A notice of redemption may not be conditional. 
  

 36 

 Section 3.05 Deposit of Redemption Price. (a) One Business Day prior to the
redemption date, the Company shall deposit with the Trustee or with the Paying Agent money sufficient to pay the redemption price of and accrued interest on all the Notes to be redeemed on that date. The Trustee or the Paying Agent shall promptly
return to the Company any money deposited with the Trustee or the Paying Agent by the Company in excess of the amounts necessary to pay the redemption price of, and accrued interest on, all Notes to be redeemed. 
 (b) If the Company complies with the provisions of Section 3.05(a), on and after the redemption date, interest shall cease to accrue on the
Notes or the portions of the Notes called for redemption. If a Note is redeemed on or after an interest record date but on or prior to the related interest payment date, then any accrued and unpaid interest shall be paid to the Person in whose name
such Note was registered at the close of business on such record date. If any Note called for redemption shall not be so paid upon surrender for redemption because of the failure of the Company to comply with Section 3.05(a), interest shall be paid
on the unpaid principal, from the redemption date until such principal is paid, and, to the extent lawful, on any interest not paid on such unpaid principal, in each case at the rate provided in the Notes. 
 Section 3.06 Notes Redeemed in Part. Upon surrender of a Note that is redeemed in part, the Company shall issue and the Trustee,
upon receipt of a Company Order, 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. 
 Section 3.07 Optional Redemption. 
 (a) At any time prior to November 1, 2014, the Notes may be redeemed, in whole or in part, at the option of the Company, at a redemption price equal to 100% of the principal amount of the Notes to be
redeemed plus the Applicable Premium as of, and accrued and unpaid interest, if any, to, the redemption date. 
 (b)
Except as provided Section 3.07(a) and (c), the Notes shall not be redeemable at the Company’s option prior to November 1, 2014. On or after November 1, 2014, the Company may redeem all or a part of the Notes upon not less than 30 nor
more than 60 days’ notice, at the redemption prices expressed as percentages of principal amount set forth below plus accrued and unpaid interest, if any, on the Notes redeemed to the applicable redemption date, subject to the right of Holders
of record on the relevant record date to receive interest due on the relevant interest payment date, if redeemed during the twelve-month period beginning on November 1 of the years indicated below:

the Company may on any one or more occasions redeem up to 35% of the aggregate principal amount of Notes originally issued, including any additional Notes issued pursuant to Section 2.16, at a redemption price of 107.125% of the principal
amount of the Notes to be redeemed on the redemption date with the net cash proceeds of one or more Equity Offerings; provided that: 
 (i) at least 65% of the aggregate principal amount of Notes originally issued, including any additional Notes issued pursuant to Section 2.16, remains outstanding immediately after the occurrence of
such redemption, excluding Notes held by the Company or any of its Subsidiaries; and

Section 3.07 shall be made pursuant to the provisions of Section 3.01 through 3.06 hereof. 
 Section 3.08
Offer to Purchase by Application of Excess Proceeds. (a) In the event that, pursuant to Section 4.10(e) hereof, the Company shall be required to commence an Asset Sale Offer, it shall follow the procedures specified below. 
 (b) The Asset Sale Offer shall remain open for a period of 20 Business Days following its commencement and no longer, except to the extent
that a longer period is required by applicable law (the “Offer Period”). No later than five Business Days after the termination of the Offer Period (the “Purchase Date”), the Company shall purchase the aggregate
principal amount (or accreted value, as applicable), plus accrued and unpaid interest, if any (except as provided in Section 3.08(c)), of Notes and other senior Indebtedness of the Company required to be purchased pursuant to Section 4.10(e) hereof
(on a pro rata basis if Notes and other senior Indebtedness of the Company tendered are in excess of the Excess Proceeds) (which maximum amount shall be the “Offer Amount”) or, if less than the Offer Amount has been tendered, all
Notes and other senior Indebtedness tendered in response to the Asset Sale Offer. Payment for any Notes so purchased shall be made in the same manner as interest payments are made. 
 (c) If the Purchase Date is on or after an interest record date and on or before the related interest payment date, any accrued and unpaid
interest, if any, shall be paid to the Person in whose name a Note is registered at the close of business on such record date, and no additional interest shall be payable to Holders who tender Notes pursuant to the Asset Sale Offer. 
  

 38 

 (d) Upon the commencement of an Asset Sale Offer, the Company shall send, by first class
mail, a notice to the Trustee and each of the Holders, with a copy to the Trustee. The notice shall contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Asset Sale Offer. The Asset Sale Offer shall
be made to all Holders. The notice, which shall govern the terms of the Asset Sale Offer, shall state: 
 (i)
that the Asset Sale Offer is being made pursuant to this Section 3.08 and Section 4.10 hereof and the length of time the Asset Sale Offer shall remain open; 
 (ii) that any Note not tendered or accepted for payment shall continue to accrue interest; 
 (iii) that, unless the Company defaults in making such payment, any Note accepted for payment pursuant to the Asset Sale
Offer shall cease to accrue interest after the Purchase Date; 
 (iv) that Holders electing to have a Note
purchased pursuant to an Asset Sale Offer may elect to have Notes purchased in a minimum denomination of $2,000 and integral multiples of $1,000 only; 
 (v) that Holders electing to have a Note purchased pursuant to any Asset Sale Offer shall be required to surrender the Note, with the form entitled “Option of Holder to Elect Purchase” on the

 (vi) that Holders shall be entitled to withdraw their election if the Company, the depositary or the Paying Agent, as the
case may be, receives, not later than the expiration of the Offer Period, a telegram, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Note the Holder delivered for purchase and a statement that such
Holder is withdrawing his election to have such Note purchased; 
 (vii) that, if the aggregate principal amount
(or accreted value, as applicable) of Notes and other senior Indebtedness of the Company surrendered by Holders exceeds the Offer Amount, the Company shall select the Notes to be purchased on a pro rata basis (with such adjustments as may be
deemed appropriate by the Company so that only Notes in minimum denominations of $2,000 and integral multiples of $1,000, shall be purchased); and 
  

 39 

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

 (a) The Company shall maintain in the Borough of Manhattan, the City of New York, an office or agency (which may be an office of the Trustee
or an affiliate of the Trustee, Registrar or co-registrar) where Notes may be surrendered for registration of transfer or for exchange and where notices and demands to or upon the 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 of the Trustee. 
 (b) 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.

 (i) all quarterly and annual reports that would be required to be filed with the SEC on Forms 10-Q and 10-K if the Company

the SEC will not accept such a filing). To the extent such filings are made, the reports shall be deemed to be furnished to the Trustee and the Holders. 
 (c) If the Company is no longer subject to the periodic reporting requirements of the Exchange Act for any reason, the Company shall nevertheless continue filing the reports specified in Section 4.03(a)
with the SEC within the time periods specified in the SEC’s rules and regulations applicable to a registrant that is not an accelerated filer or a large accelerated filer unless the SEC will not accept such a filing. The Company agrees that it

Section 4.03, and the Company will satisfy its obligations under this Section 4.03 with respect to financial information relating to the Company by furnishing financial information relating to such direct or indirect parent;
provided that such financial information is accompanied by consolidating information that explains in reasonable detail the differences between the information relating to such direct or indirect parent and any of its Subsidiaries other than
the Company and its Subsidiaries, on the one hand, and the information relating to the Company and its Subsidiaries on a standalone basis, on the other hand. 
 (e) The Company agrees that, for so long as any Notes remain outstanding, at any time it is not required to file the reports required pursuant to this Section 4.03 with the SEC, it shall furnish to
the Holders and to securities analysts and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

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) and that to the best of his or her knowledge no
event has occurred and remains in existence by reason of which payments on account of the principal of or interest, if any, on the Notes is prohibited or if such event has occurred, a description of the event and what action the Company is taking or
proposes to take with respect thereto. 
 (b) So long as not contrary to the then current recommendations of the American
Institute of Certified Public Accountants, the year-end financial statements delivered pursuant to Section 4.03(a) above shall be accompanied by a written statement of the Company’s independent public accountants (who shall be a firm of
established national reputation) that in making the examination necessary for certification of such financial statements, nothing has come to their attention that would lead them to believe that the Company has violated any provisions of Article 4
or Article 5 hereof or, if any such violation has occurred, specifying the nature and period of existence thereof, it being understood that such accountants shall not be liable directly or indirectly to any Person for any failure to obtain knowledge
of any such violation. 
 (c) The Company shall, so long as any of the Notes are outstanding, deliver to the Trustee, promptly
after the occurrence thereof, notice of any event that constitutes or, with the giving of notice or the passage of time or both, would constitute Default or Event of Default, an Officers’ Certificate specifying such Default or Event of Default

payment is not adverse in any material respect to the Holders. 
 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.

Restricted Subsidiaries’ Equity Interests (including, without limitation, any payment in connection with any merger or consolidation involving the Company or any of its Restricted Subsidiaries) or to the direct or indirect holders of the
Company’s or any of its Restricted Subsidiaries’ Equity Interests in their capacity as such (other than dividends or distributions payable in Equity Interests (other than Disqualified Stock) of the Company or to the Company or a Restricted
Subsidiary of the Company); 
 (ii) purchase, redeem or otherwise acquire or retire for value (including,
without limitation, in connection with any merger or consolidation involving the Company) any Equity Interests of the Company or any direct or indirect parent of the Company (other than (1) any such Equity Interests owned by the Company or any

connection therewith); 
 (iii) make any payment on or with respect to, or purchase, redeem, defease or
otherwise acquire or retire for value any Indebtedness that is subordinated to the Notes (other than intercompany Indebtedness), except a payment of interest or a payment of principal at Stated Maturity (or within one year of final maturity); or

 (iv) make any Restricted Investment (all such payments and other actions set forth in these clauses
(i) through (iv) of this Section 4.07(a) occurring since the date of this Indenture, being collectively referred to as “Restricted Payments”); 
 unless, at the time of and after giving effect to such Restricted Payment: 
 (i) no Default or Event of Default has occurred and is continuing or would occur as a consequence of the Restricted Payment; and 
 (ii) the Company’s Debt to Adjusted Consolidated Cash Flow Ratio would have been no greater than 7.0 to 1 after giving
effect to the incurrence of any Indebtedness the net proceeds of which are used to finance such Restricted Payment as if the same had occurred at the beginning of the most recently ended four full fiscal quarter period of the Company for which
internal financial statements are available. 
  

 44 

 (b) The preceding provisions shall not prohibit: 
 (i) the payment of any dividend within 60 days after the date of declaration of that dividend if at said date of declaration
such payment would have complied with the provisions of this Indenture; 
 (ii) the making of any Restricted
Payment in exchange for, or out of the net cash proceeds from the sale (other than to a Subsidiary of the Company) of, Equity Interests of the Company (other than any Disqualified Stock); 
 (iii) the defeasance, redemption, repurchase, or other acquisition of subordinated Indebtedness with the net cash proceeds

 (vii) other Restricted Payments in an aggregate amount not to exceed $50.0 million at any time outstanding. 
  

 45 

 (c) The Board of Directors may designate any Restricted Subsidiary to be an Unrestricted
Subsidiary if such designation would not cause a Default. For purposes of making such determination, all outstanding Investments by the Company and its Restricted Subsidiaries (except to the extent repaid in cash) in the Subsidiary so designated
shall be deemed to be Restricted Payments at the time of the designation. All of those outstanding Investments shall be deemed to constitute Investments in an amount equal to the fair market value of the Investments at the time of such designation.
Such designation shall only be permitted if the Restricted Payment would be permitted at the time and if the Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. The Board of Directors may designate any Unrestricted
Subsidiary to be a Restricted Subsidiary if the designation would not cause a Default or an Event of Default. 
 (d) The amount
of all Restricted Payments (other than cash) shall be the fair market value on the date of the Restricted Payment of the assets or securities proposed to be transferred or issued by the Company or the applicable Restricted Subsidiary, as the case
may be, pursuant to the Restricted Payment. The fair market value of any property, assets or Investments required by this Section 4.07 to be valued will be valued by the Board of Directors and evidenced by a Board Resolution set forth in an
Officers’ Certificate delivered to the Trustee.

(iii) make loans or advances to the Company; or 
 (iv) transfer any of its properties or assets to the Company.

renewals, increases, supplements, refundings, replacements or refinancings thereof; provided that

  

 46 

 
either (1) such amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings are not materially more restrictive, taken as a whole,
with respect to such dividend and other payment restrictions than those contained in the applicable series of Existing Indebtedness as in effect on the date hereof or (2) the Company determines that any such encumbrance or restriction shall not
materially affect the Company’s ability to pay interest or principal, when due, on the Notes (which determination shall be made in the good faith judgment of Board of Directors (and evidenced by a Board Resolution), which determination shall be
conclusively binding); 
 (ii) Indebtedness of any Restricted Subsidiary under any Credit Facility that is
permitted to be incurred or outstanding pursuant to Section 4.09; provided that such Credit Facility and Indebtedness contain only such encumbrances and restrictions on such Restricted Subsidiary’s ability to engage in the activities set
forth in clauses (i) through (iv) of Section 4.08(a) as are, at the time such Credit Facility is entered into or amended, modified, restated, renewed, increased, supplemented, refunded, replaced or refinanced, ordinary and customary for a
Credit Facility of that type as determined in the good faith judgment of Board of Directors (and evidenced in a Board Resolution), which determination shall be conclusively binding;

which the Subsidiary becomes a Restricted Subsidiary, and as the same may be amended, modified, restated, renewed, increased, supplemented, refunded, replaced or refinanced; provided that such amendments, modifications, restatements,
renewals, increases, supplements, refundings, replacement or refinancings are no more restrictive, taken as a whole, with respect to the dividend and other payment restrictions than those contained in the applicable series of Indebtedness of such
Subsidiary as in effect on the date on which such Subsidiary becomes a Restricted Subsidiary; 
 (iv) any
Indebtedness incurred in compliance with Section 4.09 or any agreement pursuant to which such Indebtedness is issued if the encumbrance or restriction applies only in the event of a payment default or default with respect to a financial covenant
contained in the Indebtedness or agreement and the encumbrance or restriction is not materially more disadvantageous to the Holders than is customary in comparable financings (as determined by the Company) and the Company determines that any such
encumbrance or restriction shall not materially affect the Company’s ability to pay interest or principal on the Notes; 
 (v) this Indenture; 
  

 47 

 (vi) applicable law; 
 (vii) any instrument governing Indebtedness or Capital Stock of a Person acquired by the Company or any of its Restricted

Person, or the properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired, provided that, in the case of Indebtedness, the Indebtedness was permitted by the terms of this Indenture to be
incurred;

the agreements governing the Permitted Refinancing Indebtedness are not materially more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness being refinanced or (2) the Company determines that any
such encumbrance or restriction shall not materially affect the Company’s ability to pay interest or principal, when due, on the Notes (which determination shall be made in the good faith judgment of Board of Directors (and evidenced by a Board
Resolution), which determination shall be conclusively binding);

customers under contracts entered into in the ordinary course of business; and 
 (xv) Indebtedness permitted to
be incurred pursuant to Section 4.09(b)(xiv); provided that the Company determines that any such encumbrance or restriction shall not materially affect the Company’s ability to pay interest or principal, when due, on the notes (which
determination shall be made in the good faith judgment of the Board of Directors (and evidenced by a Board Resolution), which determination shall be conclusively binding). 
 Section 4.09 Incurrence of Indebtedness and Issuance of Preferred Stock. (a) The Company shall not, and shall not permit
any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “incur”) any Indebtedness
(including Acquired Debt) and the Company shall not issue any Disqualified Stock and shall not permit any of its Restricted Subsidiaries to issue any shares of preferred stock; provided that the Company may incur Indebtedness (including
Acquired Debt) or issue shares of Disqualified Stock and the Company’s Restricted Subsidiaries may incur Indebtedness (including Acquired Debt) or issue preferred stock if, in each case, the Company’s Debt to Adjusted Consolidated Cash
Flow Ratio at the time of incurrence of the Indebtedness or the issuance of the Disqualified Stock or preferred stock, after giving pro forma effect to such incurrence or issuance as of such date and to the use of proceeds from such
incurrence or issuance as if the same had occurred at the beginning of the most recently ended four full fiscal quarter period of the Company for which internal financial statements are available, would have been no greater than 7.0 to 1.

 (b) Section 4.09(a) shall not prohibit the incurrence of any of the following items of Indebtedness or the issuance of
any of the following items of Disqualified Stock or preferred stock (collectively, “Permitted Debt”): 
 (i) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness under the Senior Credit Facility in an aggregate principal amount (with letters of credit being deemed to have a principal amount equal to the maximum
potential liability of the Company and its Restricted Subsidiaries thereunder) at any one time outstanding not to exceed $250.0 million; 
 (ii) the incurrence by the Company or its Restricted Subsidiaries of the Existing Indebtedness; 
 (iii) the incurrence by the Company of the Indebtedness represented by the Notes to be issued on the date hereof;

improvement of property, plant or equipment used in the business of the Company or such Restricted Subsidiary, in an aggregate principal amount, including all Permitted Refinancing Indebtedness incurred to refund, refinance or replace any other
Indebtedness incurred pursuant to this Section 4.09(b)(iv), not to exceed $50.0 million at any one time outstanding; 
 (v) the incurrence by the Company or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to extend, refinance, renew, replace, defease or refund Indebtedness of the
Company or any of its Restricted Subsidiaries or Disqualified Stock of the Company (other than intercompany Indebtedness) that was permitted by this Indenture to be incurred under Section 4.09(a) or clauses (ii), (iii), this clause (v) or
clause (ix) of Section 4.09(b); 
 (vi) the incurrence by the Company or any of its Restricted
Subsidiaries of intercompany Indebtedness between or among the Company and any of its Restricted Subsidiaries; provided, however, that if the Company is the obligor on such Indebtedness, such Indebtedness is expressly subordinated to
the prior payment in full in cash of all obligations with respect to the Notes and that: 
 (1) any subsequent
issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than the Company or a Restricted Subsidiary; and 
 (2) any sale or other transfer of any such Indebtedness to a Person that is not either the Company or a Restricted
Subsidiary; 
 shall be deemed, in each case, to constitute an incurrence of the Indebtedness by the Company or the Restricted Subsidiary, as
the case may be; 
 (vii) the incurrence by the Company or any of its Restricted Subsidiaries of Hedging
Obligations that are incurred for the purpose of fixing or hedging (1) interest rate risk or (2) currency exchange risk, and, in either case, not for speculative purposes; 
  

 50 

 (viii) the guarantee by the Company or any of its Restricted Subsidiaries
of Indebtedness of the Company or a Restricted Subsidiary of the Company that was permitted to be incurred by another provision of this Indenture; 
 (ix) the incurrence by the Company or any of its Restricted Subsidiaries of Acquired Debt in connection with the acquisition of assets or a new Subsidiary and the incurrence by the Company’s
Restricted Subsidiaries of Indebtedness as a result of the designation of an Unrestricted Subsidiary as a Restricted Subsidiary; provided that, in the case of any such incurrence of Acquired Debt, such Acquired Debt was incurred by the prior
owner of such assets or such Restricted Subsidiary prior to such acquisition by the Company or one of its Restricted Subsidiaries and was not incurred in connection with, or in contemplation of, the acquisition by the Company or one of its
Restricted Subsidiaries; and provided further that, in the case of any incurrence pursuant to this Section 4.09(b)(ix), as a result of such acquisition by the Company or one of its Restricted Subsidiaries, the Company’s Debt to Adjusted
Consolidated Cash Flow Ratio at the time of incurrence of such Acquired Debt, after giving pro forma effect to such incurrence as if the same had occurred at the beginning of the most recently ended four full fiscal quarter period of the Company for
which internal financial statements are available, would have been either (1) no greater than 7.0 to 1 or (2) less than the Company’s Debt to Adjusted Consolidated Cash Flow Ratio for the same period without giving pro forma
effect to such incurrence; 
 (x) the incurrence by the Company or any of its Restricted Subsidiaries of any
Indebtedness in respect of (1) performance bonds, bankers’ acceptances, letters of credit, surety or appeal bonds or similar instruments provided by the Company or any Restricted Subsidiary in the ordinary course of business, (2) the
financing of insurance premiums in the ordinary course of business or (3) netting, overdraft protection and other arrangements arising under standard business terms of any bank at which the Company or any Restricted Subsidiary maintains an
overdraft, cash pooling or other similar facility or arrangement; 
 (xi) the incurrence by the Company or any
of its Restricted Subsidiaries of any Indebtedness arising from the honoring by a bank or other financial institution of a check, draft or similar instrument drawn against insufficient funds in the ordinary course of business, provided that
such Indebtedness is extinguished within five Business Days of its incurrence; 
 (xii) the incurrence by the
Company or any of its Restricted Subsidiaries of any Indebtedness consisting of indemnification, adjustment of purchase price, earn-out or similar obligations of the Company or any Restricted Subsidiary, in each case incurred in connection with the
acquisition or disposition of any assets, business or Person by the Company or any Restricted Subsidiary; 
  

 51 

 (xiii) the incurrence by the Company or any of its Restricted Subsidiaries
of any Guarantees in the ordinary course of business of the obligations of suppliers, customers, franchisers and licensees; 
 (xiv) the incurrence by Foreign Subsidiaries of additional Indebtedness, the proceeds of which are used for ordinary course business purposes, in an aggregate principal amount, at any time outstanding,
not to exceed $25.0 million; and 
 (xv) the incurrence by the Company or any of its Restricted Subsidiaries
since the date hereof of additional Indebtedness and/or the issuance by the Company of Disqualified Stock in an aggregate principal amount, accreted value or liquidation preference, as applicable, at any time outstanding, not to exceed $100.0
million. 
 (c) The Company shall not incur any Indebtedness that is contractually subordinated in right of payment to any other
Indebtedness of the Company unless such Indebtedness is contractually subordinated in right of payment to the Notes on substantially identical terms; provided, however, that no Indebtedness the Company shall be deemed to be
contractually subordinated in right of payment to any other indebtedness of the Company solely by virtue of being unsecured. 
 (d) For purposes of determining compliance with this Section 4.09, in the event that an item of Indebtedness meets the criteria of more than one of the categories of Permitted Debt described in clauses (i) through (xv) of
Section 4.09(b) above or is entitled to be incurred pursuant to Section 4.09(a), the Company shall, in its sole discretion, classify (or later reclassify in whole or in part) such item of Indebtedness in any manner that complies with this
Section 4.09. Accrual of interest accretion or amortization of original issue discount and the payment of interest in the form of additional Indebtedness shall not be deemed to be an incurrence of Indebtedness for purposes of this
Section 4.09. For the avoidance of doubt, any such accretion or payment is considered, for purposes of Section 4.09(b)(v), to be permitted and outstanding under the paragraph or clause pursuant to which the underlying Indebtedness was
incurred. Indebtedness under the revolving portion of the Senior Credit Facility outstanding on the date hereof shall be deemed to have been incurred on such date in reliance on the exception provided by Section 4.09(b)(i), and all other
Indebtedness under the Senior Credit Facility or the Tower Cash Flow Facilities outstanding on the date hereof shall be deemed to have been incurred on such date in reliance on the exception provided by Section 4.09(b)(ii).

 Section 4.10 Asset Sales. (a) The Company shall not, and shall not permit
any of its Restricted Subsidiaries to, consummate an Asset Sale unless: 
 (i) the Company (or the Restricted
Subsidiary, as the case may be) receives consideration at the time of the Asset Sale at least equal to the fair market value of the assets or Equity Interests issued or sold or otherwise disposed of; 
 (ii) fair market value is determined by the Board of Directors and evidenced by a Board Resolution set forth in an
Officers’ Certificate delivered to the Trustee; and 
 (iii) except in the case of a Tower Asset Exchange,
at least 75% of the consideration received in such Asset Sale by the Company or such Restricted Subsidiary is in the form of cash or Cash Equivalents. 
 (b) For purposes of Section 4.10(a)(iii) above only, each of the following shall be deemed to be cash: 
 (i) any liabilities, as shown on the Company’s or such Restricted Subsidiary’s most recent balance sheet, of the Company or any Restricted Subsidiary (other than contingent liabilities and
liabilities that are by their terms subordinated to the Notes or any Guarantee of the Notes) that are assumed by the transferee of any assets pursuant to a customary novation agreement that releases the Company or the Restricted Subsidiary from
further liability; 
 (ii) any securities, notes or other obligations received by the Company or any Restricted
Subsidiary from the transferee that are converted by the Company or the Restricted Subsidiary into cash within 90 days of the applicable Asset Sale, to the extent of the cash received in that conversion; and 
 (iii) any Designated Noncash Consideration received by the Company or any of its Restricted Subsidiaries in an Asset Sale
having an aggregate fair market value, taken together with all other Designated Noncash Consideration received pursuant to this Section 4.10(b)(iii), not to exceed $150.0 million in the aggregate at any time outstanding (with the fair market
value of each item of Designated Noncash Consideration being measured at the time received and without giving effect to subsequent changes in value). 
  

 53 

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

 (iii) acquire all or substantially all the assets of a Permitted Business; 
 (iv) acquire Voting Stock of a Permitted Business from a Person that is not a Subsidiary of the Company; provided
that, after giving effect to the acquisition, the Company or its Restricted Subsidiary owns a majority of the Voting Stock of that Permitted Business; or 
 (v) make a capital expenditure or acquire other long-term assets (including long-term land use easements, ground leases and similar land rights) that are used or useful in a Permitted Business.

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

  

 54 

 
the Company tendered into the Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee shall select the Notes and such other senior Indebtedness to be purchased on a pro rata basis.
Upon completion of the Asset Sale Offer, the amount of Excess Proceeds shall be reset at zero. 
 (f) The Company shall comply
with the requirements of Section 14(e) of the Exchange Act and any other securities laws or regulations to the extent those laws and regulations are applicable to any Asset Sale Offer. If the provisions of any of the applicable securities laws
or securities regulations conflict with the provisions of this Section 4.10, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 4.10 by
virtue of the compliance. 
 Section 4.11 Transactions with Affiliates. (a) The Company shall not, and shall
not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction,
contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate (each of the foregoing, an “Affiliate Transaction”), unless: 
 (i) such Affiliate Transaction is on terms that are no less favorable to the Company or the relevant Restricted Subsidiary
than those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated Person; and 
 (ii) the Company delivers to the Trustee: 
 (1) with respect to
any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $10.0 million, a Board Resolution set forth in an Officers’ Certificate certifying that the Affiliate Transaction complies with
Section 4.11(a)(i) and that the Affiliate Transaction has been approved by a majority of the disinterested members of the Board of Directors; and 
 (2) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $35.0 million, an opinion as to the fairness to the Holders of the
Affiliate Transaction from a financial point of view issued by an accounting, appraisal or investment banking firm of national standing. 
  

 55 

 (b) Notwithstanding the foregoing, the following items shall not be deemed to be Affiliate
Transactions: 
 (i) any employment arrangements with any executive officer of the Company or a Restricted
Subsidiary that is entered into by the Company or any of its Restricted Subsidiaries in the ordinary course of business and consistent with compensation arrangements of similarly situated executive officers at comparable companies engaged in
Permitted Businesses; 
 (ii) transactions between or among the Company and/or its Restricted Subsidiaries;

 (iii) payment of reasonable and customary directors fees; 
 (iv) Restricted Payments that are permitted by Section 4.07 and loans or advances to employees made in the ordinary
course of business and consistent with past practices; 
 (v) the issuance or sale of Equity Interests (other
than Disqualified Stock) of the Company; and 
 (vi) payments of customary fees by the Company or any of its
Restricted Subsidiaries to any independent investment bank or Affiliate of an independent investment bank made for any corporate advisory services or financial advisory, financing, underwriting or placement services or in respect of other investment
banking activities including, without limitation, in connection with acquisitions or divestitures, which are approved by a majority of the Board of Directors in good faith. 
 Section 4.12 Liens. The Company shall not, directly or indirectly, create, incur, assume or suffer to exist any Lien securing
Indebtedness on any asset directly held by the Company now owned or hereafter acquired, or any income or profits therefrom or assign or convey any right to receive income therefrom, except Permitted Liens, without providing that the Notes shall be
secured equally and ratably with (or prior to) the obligations so secured for so long as such obligations are so secured. 
 Section 4.13 Business Activities. The Company shall not, and shall not permit any Subsidiary to, engage in any business other than Permitted Businesses, except to the extent as would not be material to the Company and its
Subsidiaries taken as a whole. 
 Section 4.14 [Intentionally Omitted]. 
 Section 4.15 Offer to Repurchase Upon Change of Control. (a) If a Change of Control occurs, each Holder of Notes shall have
the right to require the Company to repurchase all or any part of principal amount equal to $2,000 or an integral multiple of $1,000 of such Holder’s Notes pursuant to the offer described below (the “Change of Control Offer”).
The offer price in any

  

 56 

 
Change of Control Offer shall be payable in cash and shall equal 101% of the aggregate principal amount of any Notes repurchased plus accrued and unpaid interest on the Notes, if any (subject to
the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date), to the date of purchase (the “Change of Control Payment”). Within 30 days following any Change of Control,
the Company shall mail a notice to each Holder describing the transaction or transactions that constitute the Change of Control and offering to repurchase Notes on the date specified in the notice (the “Change of Control Payment
Date”). The Change of Control Payment Date shall be no earlier than 30 days and no later than 60 days from the date the notice is mailed, pursuant to the procedures required by this Indenture and described in such notice. 
 (b) On the Change of Control Payment Date, the Company shall, to the extent lawful: 
 (i) accept for payment all Notes or portions of the Notes properly tendered pursuant to the Change of Control Offer;

 (ii) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes
or portions of Notes properly tendered; and 
 (iii) deliver or cause to be delivered to the Trustee the Notes
so accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions of the Notes being purchased by the Company. 
 (c) The Paying Agent shall promptly mail to each Holder of Notes properly tendered the Change of Control Payment for such Notes, and the Trustee shall promptly authenticate and mail, or cause to be
transferred by book entry, to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided that the new Note shall be in a principal amount of $2,000 or an integral multiple of $1,000.

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

 57 

 (e) The Company shall not be required to make a Change of Control Offer upon a Change of
Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Indenture applicable to a Change of Control Offer made by the Company and purchases all Notes
properly tendered and not withdrawn under such Change of Control Offer. In addition, notwithstanding the occurrence of a Change of Control, the Company shall not be obligated to make a Change of Control Offer in the event it has exercised its rights
to redeem all of the outstanding Notes as provided under Section 3.07. A Change of Control Offer may be made in advance of a Change of Control and conditioned upon such Change of Control if a definitive agreement is in place for the Change of
Control at the time of making the Change of Control Offer. The provisions under this Indenture relating to the Company’s obligation to make an offer to repurchase the Notes as a result of a Change of Control may be waived or modified with the
written consent of the Holders of a majority in principal amount of the Notes then outstanding. 
 Section 4.16 Sale and
Leaseback Transactions. The Company shall not enter into any sale and leaseback transaction; provided that the Company may enter into a sale and leaseback transaction if: 
 (i) the Company could have: 
 (1) incurred Indebtedness in an amount equal to the Attributable Debt relating to such sale and leaseback transaction pursuant to Section 4.09; and 
 (2) incurred a Lien to secure such Indebtedness pursuant to Section 4.12; and 
 (ii) the transfer of assets in the sale and leaseback transaction is permitted by, and the Company applies the proceeds of
such transaction in compliance with, Section 3.08 and Section 4.10(e). 
 Section 4.17 [Intentionally
Omitted]. 
 Section 4.18 Limitation on Issuances of Guarantees of Indebtedness. The Company shall not permit
any Restricted Subsidiary, directly or indirectly, to Guarantee or pledge any assets to secure the payment of any other Indebtedness of the Company unless such Subsidiary simultaneously executes and delivers a supplemental indenture to this
Indenture providing for the Guarantee of the payment of the Notes by such Subsidiary, which Guarantee shall be senior to or pari passu with such Subsidiary’s Guarantee of or pledge to secure such other Indebtedness. Notwithstanding the
foregoing, any Guarantee by a Subsidiary of the Notes shall provide by its terms that it shall be automatically and unconditionally released and discharged upon any sale, exchange or transfer, to any Person other than a Subsidiary of the Company, of
all of the Company’s stock in, or all or substantially all the assets of, such Subsidiary, which sale, exchange or transfer is made in compliance with the applicable provisions of this Indenture.

4.07, 4.08, 4.09, 4.10, 4.11, 4.13 and Section 5.01(ii)(4) (collectively, the “Suspended Covenants”) shall no longer be in effect if on any date the Company attains Investment Grade Status and no Default or Event of Default shall
have occurred and be continuing. If at any time the Company’s credit rating is downgraded from Investment Grade Status, then the Suspended Covenants shall thereafter be reinstated as if such covenants had never been suspended and be applicable
pursuant to the terms of this Indenture (including in connection with performing any calculation or assessment to determine compliance with the terms of this Indenture), unless and until the Company subsequently attains Investment Grade Status (in
which event the Suspended Covenants shall again no longer be in effect for such time that the Company maintains Investment Grade Status); provided, however, that no Default, Event of Default or breach of any kind shall be deemed to
exist under this Indenture with respect to the Suspended Covenants based on, and none of the Company or any of its Subsidiaries shall bear any liability for, any actions taken or events occurring after the Company attains Investment Grade Status and
before any reinstatement of such Suspended Covenants as provided above, or any actions taken at any time pursuant to any contractual obligation arising prior to such reinstatement, regardless of whether such actions or events would have been
permitted if the applicable Suspended Covenants remained in effect during such period.

 Section 6.02 Acceleration. If any Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount at maturity of the then outstanding Notes may
declare all the principal of, and accrued and accrued and unpaid interest if any, on such Notes to be due and payable immediately. Notwithstanding the foregoing, in the case of an Event of Default arising from Section 6.01(a)(vii) or Section
6.01(a)(viii), with respect to the Company, all outstanding Notes shall be due and payable without further action or notice. Holders may not enforce this Indenture or the Notes except as provided in this Indenture. Subject to certain limitations,
Holders of a majority in principal amount at maturity of the then outstanding Notes may direct the Trustee in its exercise of any trust or power. 
 Section 6.03 Other Remedies. (a) If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal of, premium, if any, and
interest on the Notes or to enforce the performance of any provision of the Notes or this Indenture. 
  

 63 

 (b) The Trustee may maintain a proceeding even if it does not possess any of the Notes or
does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder of the Notes in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or
acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law. 
 Section 6.04 Waiver
of Past Defaults. Holders of not less than a majority in aggregate principal amount of the then outstanding Notes by notice to the Trustee may on behalf of the Holders of all of the Notes waive an existing Default or Event of Default and its
consequences hereunder, except a continuing Default or Event of Default in the payment of the principal of, premium, if any, or interest on, the Notes (including in connection with an offer to purchase) (provided, however, that the
Holders of a majority in aggregate principal amount of the then outstanding Notes may rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration). Upon any such waiver, such Default shall
cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Supplemental Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent
thereon. 
 Section 6.05 Control by Majority. Holders of a majority in principal amount of the then outstanding
Notes may direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with
law or this Indenture that the Trustee determines may be unduly prejudicial to the rights of other Holders of Notes or that may involve the Trustee in personal liability. Prior to taking any action hereunder, the Trustee shall be entitled to
indemnification satisfactory to it in its sole discretion against all losses and expenses caused by taking or not taking such action. 
 Section 6.06 Limitation on Suits. (a) A Holder of a Note may pursue a remedy with respect to this Supplemental Indenture or the Notes only if: 
 (i) the Holder of a Note gives to the Trustee written notice of a continuing Event of Default; 
 (ii) the Holders of at least 25% in principal amount of the then outstanding Notes make a written request to the Trustee to
pursue the remedy; 
 (iii) such Holders of Notes offer and, if requested, provide to the Trustee indemnity
satisfactory to the Trustee against any loss, liability or expense; 
  

 64 

 (iv) the Trustee does not comply with the request within 60 days after
receipt of the request and the offer and, if requested, the provision of indemnity; and 
 (v) during such
60-day period the Holders of a majority in principal amount of the then outstanding Notes do not give the Trustee a direction inconsistent with the request. 
 (b) A Holder of a Note may not use this Supplemental Indenture to prejudice the rights of another Holder of a Note or to obtain a preference or priority over another Holder of a Note. 
 Section 6.07 Rights of Holders of Notes to Receive Payment. Notwithstanding any other provision of this Indenture, the right of
any Holder of a Note to receive payment of principal of, premium, if any, and interest on the Note, on or after the respective due dates expressed in the Note (including in connection with an offer to purchase), or to bring suit for the enforcement
of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder. 
 Section 6.08 Collection Suit by Trustee. If an Event of Default specified in Section 6.01(a)(i) or Section 6.01(a)(ii) occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an
express trust against the Company for the whole amount of principal of, premium, if any, and interest remaining unpaid on the Notes and interest on overdue principal and, to the extent lawful, interest and such further amount as shall be sufficient
to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. 
 Section 6.09 Trustee May File Proofs of Claim. The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims
of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders allowed in any judicial proceedings relative to the Company (or any other obligor upon
the Notes), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims and any Custodian in any such judicial proceeding is hereby
authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof. To the extent that the payment of any such compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of,
any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein
contained shall

  

 65 

 
be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or
the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 
 Section 6.10 Priorities. (a) If the Trustee collects any money pursuant to this Article 6, it shall pay out the money in the following order: 
 First: to the Trustee, its agents and attorneys for amounts due under Section 7.07 hereof, including payment of all compensation, expense and liabilities incurred, and all advances made, by the
Trustee and the costs and expenses of collection; 
 Second: to Holders for amounts due and unpaid on the Notes for
principal, premium, if any, and interest, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal, premium, if any and interest, respectively; and 
 Third: to the Company or to such party as a court of competent jurisdiction shall direct. 
 (b) The Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section 6.10. 
 Section 6.11 Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Supplemental Indenture or
in any suit against the Trustee for any action taken or omitted by it as a Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion
may assess reasonable costs, including reasonable attorneys’ fees, 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 pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in principal amount of the then outstanding Notes.

by any persons authorized to sign an Officers’ Certificate, including any person specified as so authorized in any such certificate previously delivered and not superseded. 
 (k) The permissive right of the Trustee to take any action under this Supplemental Indenture shall not be construed as a duty to so act.

 Section 7.03 Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the
owner or pledgee of the Notes and may otherwise deal with the Company or any Affiliate of the Company with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest it must
eliminate such conflict within 90 days, apply to the SEC for permission to continue as trustee or resign. Any Agent may do the same with like rights and duties. The Trustee is also subject to Section 7.10 and Section 7.11 hereof. 
 Section 7.04 Trustee’s Disclaimer. The Trustee shall not be responsible for and makes no representation as to the validity

no event described in TIA § 313(a) has occurred within the 12 months preceding the reporting date, no report need be transmitted). The Trustee also shall comply with TIA § 313(b). The Trustee shall also transmit by mail all reports as
required by TIA § 313(c).

of any claim for which it may seek indemnity promptly upon obtaining actual knowledge thereof; provided, however, that any failure so to notify the Company shall not relieve the Company of its indemnity obligations hereunder. The
Company need not reimburse any expense or indemnify against any loss, liability or expense incurred by an indemnified party through such party’s own willful misconduct, gross negligence or bad faith. 
 (b) To secure the Company’s payment obligations in this Section 7.07, the Trustee shall have a Lien prior to the Notes on all

without any further act shall be the successor Trustee. In case at the time such successor or successors by merger, conversion or consolidation to the Trustee shall succeed to the trusts created by this Supplemental Indenture any of the Notes shall
have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee, and deliver such Notes so authenticated; and if at that time any of the Notes shall not have been
authenticated, any such successor to the Trustee may authenticate such Notes either in the name of any predecessor hereunder or in the name of the successor to the Trustee; and in all such cases such certificates shall have the full force which it
is anywhere in the Notes or in this Supplemental Indenture provided that the certificate of the Trustee shall have.

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 Supplemental Indenture referred
to in (i) and (ii) below, and to have satisfied all its other obligations under such Notes and this Supplemental Indenture (and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging the

(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).

  

 73 

 
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 Supplemental Indenture and such Notes shall be unaffected thereby. In addition, upon the
Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03 hereof, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, Section 6.01(a)(iii) through Section 6.01(a)(vi)

Restricted Subsidiaries is a party or by which the Company or any of its Restricted Subsidiaries is bound; 
 (vi) the Company must have delivered to the Trustee an Opinion of Counsel to the effect that after the 91st day following the deposit, the trust funds shall not be subject to the effect of any applicable bankruptcy, insolvency,

creditors of the Company or others; and 
 (viii) the Company must deliver to the Trustee an Officers’
Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for relating to the Legal Defeasance or the Covenant Defeasance have been complied with.

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 shall be repaid to the Company. 
 Section 8.07
Reinstatement. If the Trustee or Paying Agent is unable to apply any United States dollars or non-callable Government Securities in accordance with Section 8.02 or 8.03 hereof, as the case may be, by reason of any order or judgment of
any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s obligations under this Supplemental 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

  

 76 

 
time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.02 or 8.03 hereof, as the case may be; provided, however, that, if the
Company makes any payment of principal of, premium, if any, or interest on any Note following the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money
held by the Trustee or Paying Agent. 
 ARTICLE 9 
 AMENDMENT, SUPPLEMENT AND WAIVER 
 Section 9.01 Without Consent of Holders of Notes. (a) Notwithstanding Section 9.02 of this Supplemental Indenture, the Company and the Trustee may amend or supplement this Supplemental Indenture or the Notes without the
consent of any Holder of the Notes to: 
 (i) cure any ambiguity, omission, defect or inconsistency; 

(ii) provide for uncertificated Notes in addition to or in place of Certificated Notes; 
 (iii) provide for the assumption of the Company’s obligations to Holders of Notes in the case of a merger or
consolidation; 
 (iv) make any change that would provide any additional rights or benefits to the Holders of
Notes or that does not adversely affect the legal rights under this Supplemental Indenture of any such Holder in any material respect; or 
 (v) comply with requirements of the SEC in order to effect or maintain the qualification of the Indenture under the TIA. 
 For the avoidance of doubt, nothing in this Supplemental Indenture shall be construed to require any consent of any Holder to amend or supplement the Base Indenture in any manner that does not relate to
the Notes. 
 (b) Upon the request of the Company accompanied by a Board Resolution authorizing the execution of any such
amended or supplemental indenture, and upon receipt by the Trustee of the documents described in Section 7.02 hereof, the Trustee shall join with the Company in the execution of any amended or supplemental indenture authorized or permitted by the
terms of this Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to enter into such amended or supplemental indenture that affects its own rights, duties or
immunities under this Indenture or otherwise. 
  

 77 

 Section 9.02 With Consent of Holders of Notes. (a) Except as provided below
in this Section 9.02, the Company and the Trustee may amend or supplement this Indenture (including Section 3.08, 4.10 and 4.15 hereof) and the Notes with the consent of the Holders of at least a majority in principal amount of the Notes
then outstanding, voting as a single class (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing Default or
Event of Default (other than a Default or Event of Default in the payment of the principal of, premium, if any, or interest on the Notes, except a Payment Default resulting from an acceleration that has been rescinded) or compliance with any
provision of this Indenture or the Notes may be waived with the consent of the Holders of a majority in principal amount of the then outstanding Notes, voting as a single class (including consents obtained in connection with a tender offer or
exchange offer for, or purchase of, the Notes). Section 2.09 hereof shall determine which Notes are considered to be “outstanding” for purposes of this Section 9.02. 
 (b) Upon the request of the Company accompanied by a Board Resolution authorizing the execution of any such amended or supplemental
indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee of the documents described in Section 7.02 hereof, the Trustee shall
join with the Company in the execution of such amended or supplemental indenture unless such amended or supplemental indenture directly affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the
Trustee may in its discretion, but shall not be obligated to, enter into such amended or supplemental indenture. 
 (c) It shall
not be necessary for the consent of the Holders of Notes under this Section 9.02 to approve the particular form of any proposed amendment or waiver, but it shall be sufficient if such consent approves the substance thereof. 
 (d) After an amendment, supplement or waiver under this Section becomes effective, the Company shall mail to the Holders of Notes affected
thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amended or supplemental
indenture or waiver. Subject to Sections 6.04 and 6.07 hereof, the Holders of a majority in aggregate principal amount of the Notes then outstanding, voting as a single class, may waive compliance in a particular instance by the Company with any
provision of this Indenture or the Notes. However, without the consent of each Holder affected, an amendment or waiver under this Section 9.02 or otherwise may not (with respect to any Notes held by a non-consenting Holder): 
 (i) reduce the principal amount of Notes whose Holders must consent to an amendment, supplement or waiver; 
  

 78 

 (ii) reduce the principal of or change the fixed maturity of any Note or
alter the provisions with respect to the redemption, but not any required repurchase in connection with an Asset Sale Offer or Change of Control Offer, of the Notes; 
 (iii) reduce the rate of or extend the time for payment of interest on any Note; 
 (iv) waive a Default or Event of Default in the payment of principal of or premium, if any, or interest on the Notes,
excluding a rescission of acceleration of the Notes by the Holders of at least a majority in aggregate principal amount of the Notes and a waiver of the Payment Default that resulted from such acceleration; 
 (v) make any Note payable in money other than that stated in the Notes; 
 (vi) make any change in the provisions of 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 on the Notes; 
 (vii) waive a
redemption payment, but not any payment upon a required repurchase in connection with an Asset Sale Offer or Change of Control Offer, with respect to any Note; 
 (viii) except as provided in Section 8.01 and Section 8.02 or in accordance with the terms of any Subsidiary Guarantee,
release a Subsidiary Guarantor from its obligations under its Subsidiary Guarantee or make any change in a Subsidiary Guarantee that would adversely affect the Holders; or 
 (ix) make any change in the foregoing amendment and waiver provisions. 
 Section 9.03 Compliance with Trust Indenture Act. Every amendment or supplement to this Indenture or the Notes shall be set
forth in an amended or supplemental indenture that complies with the TIA as then in effect. 
 Section 9.04 Revocation
and Effect of Consents. Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of a Note and every subsequent Holder of a Note or portion of a Note that evidences
the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note. However, any such Holder of a Note or subsequent Holder of a Note may revoke the

  

 79 

 
consent as to its Note if the Trustee receives written notice of revocation before the date the waiver, supplement or amendment becomes effective. An amendment, supplement or waiver becomes
effective in accordance with its terms and thereafter binds every Holder. 
 Section 9.05 Notation on or Exchange of
Notes. (a) The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Company in exchange for all Notes may issue and the Trustee shall, upon receipt of a Company Order,
authenticate new Notes that reflect the amendment, supplement or waiver. 
 (b) Failure to make the appropriate notation or
issue a new Note shall not affect the validity and effect of such amendment, supplement or waiver. 
 Section 9.06
Trustee to Sign Amendments, etc. The Trustee shall sign any amended or supplemental indenture authorized pursuant to this Article 9 if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the
Trustee. The Company may not sign an amended or supplemental indenture until the Board of Directors approves it. In executing any amended or supplemental indenture, the Trustee shall be entitled to receive and (subject to Section 7.01 hereof)
shall be fully protected in relying upon an Officer’s Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by this Indenture.

 CUSIP No. 228227 BA1 
 CROWN CASTLE INTERNATIONAL CORP., a corporation duly organized and existing under the laws of the State of Delaware (herein called the
“Company,” which term includes any successor Person under the Supplemental Indenture hereinafter defined), for value received, hereby promises to pay to CEDE & CO., or registered assigns, [the principal sum of $
(                         Dollars)] [the principal sum set forth on the Schedule of Exchanges of Notes attached hereto]
2 on November 1, 2019, and to pay interest thereon
from October 23, 2009 or from the most recent Payment Date (as defined below) to which interest has been paid or duly provided for, semi-annually on May 1 and November 1 (each, a “Payment Date”) in each year,
commencing May 1, 2010, at the rate of 7.125% per annum, until the principal hereof is paid or made available for payment. 
  
  
 The interest so payable, and
punctually paid or duly provided for, on any Payment Date will, as provided in the Supplemental Indenture, be paid to the Person in whose name this Note is registered at the close of business on the regular record date for such interest, which shall
be April 15 or October 15, as the case may be, next preceding such Payment Date or, if such record date is not a Business Day, at the close of business of the immediately succeeding Business Day. A “Business Day” shall
mean any day other than a Saturday, Sunday or a day on which banking institutions in the City of New York or at a place of payment are authorized by law, regulation or executive order to remain closed. If a payment date is not a Business Day at a
place of payment, payment may be made at that place on the next succeeding day that is a Business Day, and no interest shall accrue on such payment for the intervening period. Any such interest not so punctually paid or duly provided for will
forthwith cease to be payable to the Holder on such regular record date and shall be paid to the Person in whose name this Note is registered at the close of business on a subsequent special record date, which date shall be the fifteenth day next
preceding the date fixed by the Company for the payment of defaulted interest or the next succeeding Business Day if such date is not a Business Day. At least 30 days before the special record date, the Company shall mail or cause to be mailed to
each Holder, with a copy to the Trustee, a notice that states the special record date, the Payment Date, and the amount of defaulted interest, and interest payable on such defaulted interest, if any, to be paid. 
 If a Holder has given wire transfer instructions to the Company, the Company will make all payments of principal, premium and interest, if any, on that
Holder’s Notes in accordance with those instructions. All other payments on the Notes will be made at the office or agency of the Paying Agent and Registrar for the Notes within the City and State of New York unless, with respect to such other
payments, the Company elects to make interest payments by check mailed to the Holders at their address set forth in the register of Holders. Interest will be computed on the basis of a 360-day year composed of twelve 30-day months. 
 Reference is hereby made to the further provisions of this Note set forth on the reverse hereof, which further provisions shall for all purposes have the
same effect as if set forth at this place.

 [FORM OF REVERSE OF NOTE] 
  

	1.	Notes. 

 This Note is one of a duly authorized
issue of senior notes of the Company (herein called the “Notes”), issued and to be issued in one or more series under the Second Supplemental Indenture, dated as of October 23, 2009 (the “Supplemental
Indenture”), to the Indenture dated as of January 27, 2009 between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee (herein called the “Trustee,” which term includes any successor trustee
under the Supplemental Indenture), and reference is hereby made to the Supplemental Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee, and the Holders and of the
terms upon which the Notes are, and are to be, authenticated and delivered. This Note is one of the series designated on the face hereof as “7.125% Senior Notes due 2019,” limited in aggregate principal amount to $500,000,000. All terms
used in this Note which are defined in the Supplemental Indenture shall have the meanings assigned to them in the Supplemental Indenture. 
  

	2.	No Sinking Fund. 

 No sinking fund is provided
for the Notes. 
  

	3.	Optional Redemption. 

 (a) At any time prior to
November 1, 2014, the Notes may be redeemed, in whole or in part, at the option of the Company, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed plus the Applicable Premium as of, and accrued and unpaid
interest, if any, to, the redemption date. 
 (b) During the period after the date of original issuance of the Notes until November 1,
2012, the Company may on any one or more occasions redeem up to 35% of the aggregate principal amount of Notes originally issued at a redemption price of 107.125% of the principal amount of the Notes to be redeemed on the redemption date with the
net cash proceeds of one or more Equity Offerings; provided that: 
 (1) at least 65% of the aggregate principal amount
of Notes originally issued remains outstanding immediately after the occurrence of such redemption, excluding Notes held by the Company or any of its Subsidiaries; and 
 (2) the redemption occurs within 90 days of the date of the closing of the Equity Offering. 
 (c)
Except pursuant to the preceding paragraphs under this Paragraph 3, the Notes will not be redeemable at the Company’s option prior to November 1, 2014. On or after November 1, 2014,

  

 6 

 
the Company may redeem all or a part of the Notes upon not less than 30 nor more than 60 days’ notice, at the redemption prices expressed as percentages of principal amount set forth below
plus accrued and unpaid interest, if any, on the Notes redeemed to the applicable redemption date, subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date, if redeemed
during the twelve-month period beginning on November 1, of the years indicated below: 
  

				
	Year	  	Percentage	 
	 2014
	  	103.563	% 
	 2015
	  	102.375	% 
	 2016
	  	101.188	% 
	 2017
	  	100.000	% 

  

	4.	Selection and Notice of Redemption. 

 (a) If less
than all of the Notes are to be redeemed at any time, the Trustee will select Notes for redemption as follows: 
 (1) if the
Notes are listed on any national securities exchange, in compliance with the requirements of the principal national securities exchange, if any, on which the Notes are listed; or 
 (2) if the Notes are not listed on any national securities exchange, on a pro rata basis, by lot or by a method that complies with approved
legal and securities exchange requirements, if any, as the Trustee in its sole discretion shall deem fair and appropriate. 
 (b) No Notes of
$2,000 of principal amount at maturity or less will be redeemed in part. Notices of redemption will be mailed by first class mail at least 30 but not more than 60 days before the redemption date to each Holder of Notes to be redeemed at its
registered address. Notices of redemption may not be conditional. 
  

	5.	Repurchase at Option of Holder. 

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

 7 

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

	6.	Acceleration Upon Event of Default. 

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

 (b) The Holders of a majority in aggregate principal amount at maturity of the Notes then outstanding by notice to the Trustee may on behalf
of the Holders of all Notes waive any existing Default or Event of Default and its consequences under the Indenture except a continuing Default or Event of Default in the payment of interest on, or the principal of, the Notes (provided,
however, that the Holders of a majority in aggregate principal amount of the then outstanding Notes may rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration). 
 (c) The Indenture provides that if a Default occurs and is continuing and is known to the Trustee, the Trustee must mail to each Holder of the Notes notice
of the Default within 90 days after it occurs. Except in the case of a Default in the payment of principal of or interest on any Note, the

  

 8 

 
Trustee may withhold notice if and so long as a committee of its trust officers determines that withholding notice is not opposed to the interest of the Holders. In addition, the Company is
required to deliver to the Trustee, within 90 days after the end of each Fiscal Year, an Officers’ Certificate indicating whether the signers thereof know of any Default that occurred during the previous year. The Company is also required to
deliver to the Trustee, promptly after the occurrence thereof, written notice of any event that constitutes or, with the given notice or passage of time or both, would constitute a Default or Event of Default, the status thereof and what action the
Company is taking or proposes to take in respect thereof. 
  

	7.	Amendment and Modification. 

 The Supplemental
Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders under the Indenture at any time by the Company and the Trustee with
the consent of the Holders of not less than a majority in principal amount of the Notes at the time outstanding. The Indenture also contains provisions permitting the Holders of no less than a majority in principal amount of the Notes at the time
outstanding, on behalf of the Holders of all the Notes, to waive compliance by the Company with certain provisions of the Indenture and certain past Defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of
this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued in exchange herefor or in lieu hereof whether or not notation of such consent or waiver is made upon this Note or such other
Note. 
  

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

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

	9.	Transfer and Exchange. 

 As provided in the
Indenture and subject to certain limitations therein set forth, the transfer of this Note is registrable on the security register maintained by the Registrar, upon surrender of this Note for registration of transfer at the office or agency of the
Company in any place where the principal of and any interest on this Note are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Registrar duly executed by, the Holder thereof or
his attorney duly authorized in writing, and thereupon one or more new Notes, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees by the Registrar. 
  

 9 

	10.	No Service Charge. 

 No service charge shall be
made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to recover any tax or other governmental charge payable in connection therewith. 
  

	11.	Treatment as Owner. 

 Prior to due presentation
of this Note for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name the Note is registered, as the owner thereof for all purposes, whether or not such Note be overdue,
and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary. 
  

	12.	No Liability. 

 A director, officer, employee,
stockholder or incorporation, as such, of the Company shall not have any liability (except in the case of bad faith or willful misconduct) for any obligations of the Company under the Note or the Supplemental Indenture or for any claim based on, in
respect of or by reason of such obligations or their creations. Each Holder by accepting a Note waives and releases all such liability. Such waiver and release are part of the consideration for the issuance of the Notes. 
  

	13.	Governing Law. 

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