or followed by a downgrade of the Notes within the Ratings Decline Period for such Change of Control by both Rating Agencies and each Rating Agency’s rating of the Notes on any day during such Ratings Decline Period for such Change of Control
is below the rating by such Rating Agency in effect immediately preceding the first public announcement of the Change of Control (or the occurrence thereof if such Change of Control occurs prior to the first public announcement thereof). No Change

whose signature is on a Note no longer holds that office at the time the Note is authenticated, the Note will still be valid. 
 (b) A Note
will not be valid until the Trustee manually signs the certificate of authentication on the Note, with the signature conclusive evidence that the Note has been authenticated under this Indenture. 

(c) At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Notes executed by the Company
to the Trustee for authentication. The Trustee will authenticate and deliver: 
 (i) Initial Notes for original issue in the
aggregate principal amount not to exceed $400,000,000; and 
 (ii) Additional Notes from time to time for original issue in
aggregate principal amounts specified by the Company (provided that if the Additional Notes are not fungible with the Initial Notes for U.S. Federal income tax purposes, such Additional Notes will have a different CUSIP); 

after receipt by the Trustee of a Company Order specifying: 

(A) the amount of Notes to be authenticated and the date on which the Notes are to be authenticated, 

(B) whether the Notes are to be Initial Notes or Additional Notes, 

(C) whether the Notes are to be issued as one or more Global Notes or Certificated Notes, and 

(D) other information the Company may determine to include or the Trustee may reasonably request. 

(d) Initial Notes and any Additional Notes will be treated as a single class for all purposes under this Indenture and will vote together as
one class on all matters with respect to the Notes. 
 Section 2.03. Registrar, Paying Agent and Authenticating Agent; Paying Agent
to Hold Money in Trust. (a) The Company may appoint one or more “Registrars” and one or more “Paying Agents”, and the Trustee may appoint an Authenticating Agent, in which case each reference in this
Indenture to the Trustee in respect of the obligations of the Trustee to be performed by that Agent will be deemed to be references to the Agent. The Company may act as Registrar or (except for purposes of Article 9) Paying Agent. In each case the
Company and the Trustee will enter into an appropriate agreement with the Agent implementing the provisions of this Indenture relating to the obligations of the Trustee to be performed by the Agent and the related rights. The Company initially
appoints the Trustee as Registrar and Paying Agent and to act as DTC Custodian with respect to the Global Notes. 

  
 32 








 (b) The Company will require each Paying Agent other than the Trustee to agree in writing that
the Paying Agent will hold in trust for the benefit of the Holders or the Trustee all money held by the Paying Agent for the payment of principal of and interest on the Notes and will promptly notify the Trustee of any default by the Company in
making any such payment. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee and account for any funds disbursed, and the Trustee may at any time during the continuance of any payment default, upon written
request to a Paying Agent, require the Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed. Upon doing so, the Paying Agent will have no further liability for the money so paid over to the Trustee. 

Section 2.04. Replacement Notes. If a mutilated Note is surrendered to the Trustee or if a Holder claims that its Note has
been lost, destroyed or wrongfully taken, the Company will issue and the Trustee will authenticate a replacement Note of like tenor and principal amount and bearing a number not contemporaneously outstanding. Every replacement Note is an additional
obligation of the Company and entitled to the benefits of this Indenture. If required by the Trustee or the Company, an indemnity must be furnished that is sufficient in the judgment of both the Trustee and the Company to protect the Company and the
Trustee from any loss they may suffer if a Note is replaced. The Company may charge the Holder for the expenses of the Company and the Trustee in replacing a Note. In case the mutilated, lost, destroyed or wrongfully taken Note has become or is
about to become due and payable, the Company in its discretion may pay the Note instead of issuing a replacement Note. 

Section 2.05. Outstanding Notes. (a) Notes outstanding at any time are all Notes that have been authenticated by the
Trustee except for: 
 (1) Notes cancelled by the Trustee or delivered to it for cancellation; 

(2) any Note which has been replaced pursuant to Section 2.04 unless and until the Trustee and the Company receive proof
satisfactory to them that the replaced Note is held by a bona fide purchaser; and 
 (3) on or after the maturity date
or any Redemption Date in accordance with Article III or date for purchase of the Notes pursuant to an offer to purchase Notes pursuant to Section 4.09, those Notes payable or to be redeemed or purchased on that date for which the Trustee (or Paying
Agent, other than the Company or an Affiliate of the Company) holds money sufficient to pay all amounts then due. 
 (b) A Note does not
cease to be outstanding because the Company or one of its Affiliates holds the Note; provided that in determining whether the Holders of the requisite principal amount of the outstanding Notes have given or taken any request, demand,
authorization, direction, notice, consent, waiver or other action hereunder, Notes owned by the Company or any Affiliate of the Company will be disregarded and deemed not to be outstanding, (it being understood that in determining whether the
Trustee is protected in relying upon any such request, demand, authorization, direction, notice, consent, waiver or other action, only Notes which the Trustee knows to be so owned will be so disregarded). Notes so owned which have been pledged in
good faith may be regarded as outstanding if the pledgee establishes to the satisfaction of the Trustee the pledgee’s right so to act with respect to such Notes and that the pledgee is not the Company or any Affiliate of the Company. 

  
 33 








 Section 2.06. Temporary Notes. Until definitive Notes are ready for delivery,
the Company may prepare and the Trustee will authenticate temporary Notes. Temporary Notes will be substantially in the form of definitive Notes but may have insertions, substitutions, omissions and other variations determined to be appropriate by
the Officer executing the temporary Notes, as evidenced by the execution of the temporary Notes. If temporary Notes are issued, the Company will cause definitive Notes to be prepared without unreasonable delay. After the preparation of definitive
Notes, the temporary Notes will be exchangeable for definitive Notes upon surrender of the temporary Notes at the office or agency of the Company designated for the purpose pursuant to Section 4.02, without charge to the Holder. Upon surrender
for cancellation of any temporary Notes the Company will execute and the Trustee will authenticate and deliver in exchange therefor a like principal amount of definitive Notes of authorized denominations. Until so exchanged, the temporary Notes will
be entitled to the same benefits under this Indenture as definitive Notes. 
 Section 2.07. Cancellation. The
Company at any time may deliver to the Trustee for cancellation any Notes previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and may deliver to the Trustee for cancellation any Notes
previously authenticated hereunder which the Company has not issued and sold. Any Registrar or the Paying Agent will forward to the Trustee any Notes surrendered to it for transfer, exchange or payment. The Trustee will cancel all Notes surrendered
for transfer, exchange, payment or cancellation and dispose of them in accordance with its normal procedures. The Company may not issue new Notes to replace Notes it has paid in full or delivered to the Trustee for cancellation. 

Section 2.08. CUSIP, ISIN, CINS or Other Similar Numbers. The Company in issuing the Notes may use “CUSIP”,
“ISIN”, “CINS” or other similar numbers, and the Trustee will use CUSIP, ISIN, CINS or other similar numbers in notices of redemption or exchange or in offers to purchase as a convenience to Holders, the notice to 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 redemption or exchange or offer to purchase. The Company will promptly notify the Trustee of any change in the CUSIP, ISIN,
CINS or other similar numbers. 
 Section 2.09. Registration, Transfer and Exchange. (a) The Notes will be
issued in registered form only, without coupons, and the Company shall cause the Trustee to maintain a register (the “Note Register”) of the Notes, for registering the record ownership of the Notes by the Holders and
transfers and exchanges of the Notes. 
 (b) (1) Each Global Note will be registered in the name of the
Depositary or its nominee and, so long as DTC is serving as the Depositary thereof, will bear the DTC Legend. The Company has entered into a letter of representations with DTC in the form provided by DTC and the Trustee and each Agent are hereby
authorized to act in accordance with such letter and Applicable Procedures. Neither the Trustee nor any Agent shall have responsibility for any actions taken or not taken by DTC or any Depositary. 

  
 34 








 (2) Each Global Note will be delivered to the Trustee as custodian for the
Depositary. Transfers of a Global Note (but not a beneficial interest therein) will be limited to transfers thereof in whole, but not in part, to the Depositary, its successors or their respective nominees, (1) except as set forth in
Section 2.09(b)(4) and (2) except that transfers of portions thereof in the form of Certificated Notes may be made upon request of an Agent Member (for itself or on behalf of a beneficial owner) by written notice given to the Trustee by or
on behalf of the Depositary in accordance with customary procedures of the Depositary and in compliance with this Section and Section 2.11. 

(3) Members of, or direct or indirect participants in, the Depositary (“Agent Members”) will have no rights
under this Indenture with respect to any Global Note held on their behalf by the Depositary, or the Trustee as its custodian, and the Depositary 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, the Depositary or its nominee may grant proxies and otherwise authorize any Person (including any Agent Member and any Person that holds a beneficial
interest in a Global Note through an Agent Member) to take any action which a Holder is entitled to take under this Indenture or the Notes, and nothing herein will 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. 
 (4) If (x) the Depositary notifies the
Company that it is unwilling or unable to continue as Depositary for a Global Note and a successor depositary is not appointed by the Company within 90 days of the notice or (y) an Event of Default has occurred and is continuing and the Trustee
has received a request from the Depositary, the Trustee will promptly exchange each beneficial interest in the Global Note for one or more Certificated Notes in authorized denominations having an equal aggregate principal amount registered in the
name of the owner of such beneficial interest, as identified to the Trustee by the Depositary, and thereupon the Global Note will be deemed canceled. If such Note does not bear the Restricted Legend, then the Certificated Notes issued in exchange
therefor will not bear the Restricted Legend. If such Note bears the Restricted Legend, then the Certificated Notes issued in exchange therefor will bear the Restricted Legend; provided that any Holder of any such Certificated Note issued in
exchange for a beneficial interest in an Offshore Global Note prior to the expiration of the Restricted Period will have the right upon presentation to the Trustee of a duly completed Certificate of Beneficial Ownership after the Restricted Period
to exchange such Certificated Note for a Certificated Note of like tenor and amount that does not bear the Restricted Legend, registered in the name of such Holder. 

(c) Each Certificated Note will be registered in the name of the Holder thereof or its nominee. 

(d) A Holder may transfer a Note (or a beneficial interest therein) to another Person or exchange a Note (or a beneficial interest therein) for
another Note or Notes of any authorized denomination by presenting to the Trustee a written request therefor stating the name of the proposed transferee or requesting such an exchange, accompanied by any certification, opinion or other document
required by Section 2.10. The Trustee will promptly register any transfer or exchange that meets the requirements of this Section by noting the same in the register maintained by the Trustee for the purpose; provided that 

  
 35 








 (x) no transfer or exchange will be effective until it is registered in such
register and 
 (y) the Trustee will not be required (i) to issue, register the transfer of or exchange any Note for a
period of 15 days before a selection of Notes to be redeemed or purchased pursuant to an offer to purchase, (ii) to register the transfer of or exchange any Note so selected for redemption or purchase in whole or in part, except, in the case of
a partial redemption or purchase, that portion of any Note not being redeemed or purchased, or (iii) if a redemption or a purchase pursuant to an offer to purchase is to occur after a Regular Record Date but on or before the corresponding
Interest Payment Date, to register the transfer of or exchange any Note on or after the Regular Record Date and before the Redemption Date or date of purchase. Prior to the registration of any transfer, the Company, the Trustee and their agents will
treat the Person in whose name the Note is registered as the owner and Holder thereof for all purposes (whether or not the Note is overdue), and will not be affected by notice to the contrary. 

From time to time the Company will execute and the Trustee will authenticate additional Notes as necessary in order to permit the registration
of a transfer or exchange in accordance with this Section. 
 No service charge will be imposed in connection with any transfer or exchange
of any Note, but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than a transfer tax or other similar governmental charge payable upon exchange
pursuant to subsection (b)(4)). 
 (e) (1) Global Note to Global Note. If a beneficial interest in a Global Note
is transferred or exchanged for a beneficial interest in another Global Note, the Trustee will (x) record a decrease in the principal amount of the Global Note being transferred or exchanged equal to the principal amount of such transfer or
exchange and (y) record a like increase in the principal amount of the other Global Note. Any beneficial interest in one Global Note that is transferred to a Person who takes delivery in the form of an interest in another Global Note, or
exchanged for an interest in another Global Note, will, upon transfer or exchange, cease to be an interest in such Global Note and become an interest in the other Global Note and, accordingly, will thereafter be subject to all transfer and exchange
restrictions, if any, and other procedures applicable to beneficial interests in such other Global Note for as long as it remains such an interest. 

(2) Global Note to Certificated Note. If a beneficial interest in a Global Note is transferred or exchanged for a
Certificated Note, the Trustee will (x) record a decrease in the principal amount of such Global Note equal to the principal amount of such transfer or exchange and (y) deliver one or more new Certificated Notes in authorized denominations
having an equal aggregate principal amount to the transferee (in the case of a transfer) or the owner of such beneficial interest (in the case of an exchange), registered in the name of such transferee or owner, as applicable. 

  
 36 








 (3) Certificated Note to Global Note. If a Certificated Note is
transferred or exchanged for a beneficial interest in a Global Note, the Trustee will (x) cancel such Certificated Note, (y) record an increase in the principal amount of such Global Note equal to the principal amount of such transfer or
exchange and (z) in the event that such transfer or exchange involves less than the entire principal amount of the canceled Certificated Note, deliver to the Holder thereof one or more new Certificated Notes in authorized denominations having
an aggregate principal amount equal to the untransferred or unexchanged portion of the canceled Certificated Note, registered in the name of the Holder thereof. 

(4) Certificated Note to Certificated Note. If a Certificated Note is transferred or exchanged for another Certificated
Note, the Trustee will (x) cancel the Certificated Note being transferred or exchanged, (y) deliver one or more new Certificated Notes in authorized denominations having an aggregate principal amount equal to the principal amount of such
transfer or exchange to the transferee (in the case of a transfer) or the Holder of the canceled Certificated Note (in the case of an exchange), registered in the name of such transferee or Holder, as applicable, and (z) if such transfer or
exchange involves less than the entire principal amount of the canceled Certificated Note, deliver to the Holder thereof one or more Certificated Notes in authorized denominations having an aggregate principal amount equal to the untransferred or
unexchanged portion of the canceled Certificated Note, registered in the name of the Holder thereof. 
 Section 2.10.
Restrictions on Transfer and Exchange. (a) The transfer or exchange of any Note (or a beneficial interest therein) may only be made in accordance with this Section and Section 2.09 and, in the case of a Global Note (or a beneficial
interest therein), the applicable rules and procedures of the Depositary. The Trustee shall refuse to register any requested transfer or exchange that does not comply with the preceding sentence. 

(b) Subject to paragraph (c), the transfer or exchange of any Note (or a beneficial interest therein) of the type set forth in column A below
for a Note (or a beneficial interest therein) of the type set forth opposite in column B below may only be made in compliance with the certification requirements (if any) described in the clause of this paragraph set forth opposite in column C
below.

 (2) The Person requesting the transfer or exchange must deliver or cause to be
delivered to the Trustee a duly completed Regulation S Certificate; provided that if the requested transfer or exchange is made by the Holder of a Certificated Note that does not bear the Restricted Legend, then no certification is required.

 (3) The Person requesting the transfer or exchange must deliver or cause to be delivered to the Trustee (x) a duly
completed Rule 144A Certificate, (y) a duly completed Regulation S Certificate or (z) a duly completed Institutional Accredited Investor Certificate, and/or an Opinion of Counsel and such other certifications and evidence as the Company
may reasonably require in order to determine that the proposed transfer or exchange is being made in compliance with the Securities Act and any applicable securities laws of any state of the United States; provided that if the requested
transfer or exchange is made by the Holder of a Certificated Note that does not bear the Restricted Legend, then no certification is required. In the event that (i) the requested transfer or exchange takes place after the Restricted Period and
a duly completed Regulation S Certificate is delivered to the Trustee or (ii) a Certificated Note that does not bear the Restricted Legend is surrendered for transfer or exchange, upon transfer or exchange the Trustee will deliver a
Certificated Note that does not bear the Restricted Legend. 
 (4) The Person requesting the transfer or exchange must
deliver or cause to be delivered to the Trustee a duly completed Rule 144A Certificate. 
 (5) Notwithstanding anything to
the contrary contained herein, no such exchange is permitted if the requested exchange involves a beneficial interest in an Offshore Global Note during the Restricted Period. If the requested transfer involves a beneficial interest in an Offshore
Global Note during the Restricted Period, the Person requesting the transfer must deliver or cause to be delivered to the Trustee (x) a duly completed Rule 144A Certificate or (y) a duly completed Institutional Accredited Investor
Certificate and/or an Opinion of Counsel and such other certifications and evidence as the Company may reasonably require in order to determine that the proposed transfer is being made in compliance with the Securities Act and any applicable
securities laws of any state of the United States. If the requested transfer or exchange involves a beneficial interest in an Offshore Global Note following the expiration of the Restricted Period, no certification is required and the Trustee will
deliver a Certificated Note that does not bear the Restricted Legend. 
 (c) No certification is required in connection with any transfer or
exchange of any Note (or a beneficial interest therein). 
 (1) after such Note is eligible for resale pursuant to Rule 144
under the Securities Act (or a successor provision) without the need for current public information; provided that the Company has provided the Trustee with an Officers’ Certificate to that effect, and the Company may require from any
Person requesting a transfer or exchange in reliance upon this clause (1) an opinion of counsel and any other reasonable certifications and evidence in order to support such certificate; or 

(2) sold pursuant to an effective registration statement. 

  
 38 








 Any Certificated Note delivered in reliance upon this paragraph will not bear the Restricted
Legend. 
 (d) The Trustee will retain copies of all certificates, opinions and other documents received in connection with the transfer or
exchange of a Note (or a beneficial interest therein), and the Company will have the right to inspect and make copies thereof at any reasonable time upon written notice to the Trustee. 

(e) Neither the Trustee nor the Registrar shall have any duty to monitor the Company’s compliance with or have any responsibility with
respect to the Company’s compliance with any U.S. Federal or state securities laws in connection with registrations of transfers and exchanges of the Notes. The Trustee shall have no obligation or duty to monitor, determine or inquire as to
compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Notes (including any transfers between or among Depositary participants or beneficial owners of
interests in any Global Note) other than to require delivery of such certificates and other documentation, as is 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. 
 (f) Each Holder by acceptance of its Notes agrees to indemnify the
Trustee against liability that may result from the transfer, exchange or assignment of such Holder’s interest in the Note in violation of any provision of this Indenture and/or applicable U.S. Federal and state securities laws. 

Section 2.11. Offshore Global Notes. 

(a) Each Note originally sold in reliance upon Regulation S will be evidenced by one or more Offshore Global Notes that shall be deemed a
“temporary global note” for purposes of Regulation S until the expiration of the Restricted Period, whereupon such Offshore Global Note will henceforth be deemed a “permanent global note” for purposes of Regulation S and the
“temporary global note” shall also be deemed cancelled. 
 (d) Notwithstanding anything to the contrary contained herein, any owner
of a beneficial interest in an Offshore Global Note prior to the expiration of the Restricted Period shall not be entitled to receive payment of principal or interest on such beneficial interest or other amounts in respect of such beneficial
interest until (x) the expiration of the Restricted Period or (y) such beneficial interest is transferred for an interest in another Global Note or a Certificated Note. 

Section 2.12. Computation of Interest. Interest on the Notes shall be computed on the basis of a 360-day year composed of twelve
30-day months. 
 Section 2.13. Defaulted Interest. If the Company defaults on a payment of interest when due on the Notes, it
shall pay the defaulted interest, and, to the extent lawful, interest on the defaulted interest at a rate per annum that is 1% in excess of 4.625%, in accordance with the terms hereof, to the Persons who are Holders on a subsequent special record
date fixed by the 

  
 39 








 
Company, which date shall be at least five Business Days prior to the payment date fixed by the Company. At least 10 days before such special record date, the Company shall mail or send 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 defaulted interest, if any, to be paid. The Company may make payment of any defaulted
interest in any other lawful manner not inconsistent with the requirements (if applicable) of any securities exchange on which the Notes may be listed and, upon such notice as may be required by such exchange, if, after written notice given by the
Company to the Trustee of the proposed payment pursuant to this sentence, such manner of payment shall be deemed practicable by the Trustee. 

Section 2.14. 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 the Holders. If the Trustee is not the Registrar, the Company shall furnish to the Trustee at least five Business 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 the Holders; provided that, as long as the Trustee is the Registrar, no such list need be furnished. 

ARTICLE 3 

REDEMPTION AND PREPAYMENT 

Section 3.01. Election to Redeem; Notices to Trustee. If the Company elects to redeem Notes pursuant to this Article 3, at least
30 days prior to the Redemption Date but not more than 60 days before the Redemption Date, the Company shall notify the Trustee in writing of the Redemption Date, the principal amount of such Notes to be redeemed and the Redemption Price. Notice
given to the Trustee pursuant to this Section 3.01 may, at the Company’s discretion, state that any such redemption is subject to the satisfaction of one or more conditions precedent. For the avoidance of doubt, the provisions described in this
Article 3 shall not apply to repurchases of Notes by the Company on the open market or in privately negotiated transactions. 

Section 3.02. Selection by Trustee of Notes to be Redeemed. If the Company redeems fewer than all of the Notes at any time, the
Trustee will select the Notes to be redeemed by lot, on a pro rata basis or by any other method the Trustee deems to be fair and appropriate (or, in the case of Global Notes, based on the method required by the Depositary or, if it is not so
required, a method that most nearly approximates a pro rata selection as the Trustee deems fair and appropriate), unless otherwise required by law or applicable stock exchange or depositary requirements. 

The Trustee shall promptly notify the Company of the Notes selected for redemption and, in the case of any partial redemption, the principal
amount thereof to be redeemed. 
 The Company will redeem Notes of $2,000 or less in whole and not in part. For all purposes of this
Indenture unless the context otherwise requires, provisions of this Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption. 

  
 40 








 Section 3.03. Notice of Redemption. The Company will cause notices of redemption to
be mailed by first-class mail (or electronic transmission in the case of Global Notes) at least 30 but not more than 60 days before the Redemption Date to each Holder of Notes (with a copy to the Trustee) to be redeemed at its registered address.
The Company may provide in the notice that payment of the Redemption Price and performance of the Company’s obligations with respect to the redemption or purchase may be performed by another Person. Any notice may, at the Company’s
discretion, state that the redemption is subject to the satisfaction of one or more conditions precedent. 
 The notice shall identify the
Notes to be redeemed (including the CUSIP number(s) thereof) and shall state: 
 (a) the Redemption Date; 

(b) the Redemption Price; 
 (c) if
fewer than all outstanding Notes are to be redeemed, the portion of the principal amount of such Note to be redeemed and that, after the Redemption Date and upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed
portion will be issued; 
 (d) the name and address of the Paying Agent; 

(e) that Notes called for redemption must be surrendered to the Paying Agent to collect the Redemption Price; 

(f) that unless the Company defaults in making the redemption payment, or any condition to such redemption is not satisfied or waived, interest
on Notes called for redemption ceases to accrue on and after the Redemption Date; 
 (g) if such redemption is conditioned upon the
occurrence of one or more conditions precedent, the nature of such conditions precedent; 
 (h) the aggregate principal amount of Notes that
are being redeemed; 
 (i) the paragraph of the Notes and/or Section of this Indenture pursuant to which the Notes called for redemption are
being redeemed; and 
 (j) 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. 
 At the Company’s written request, the Trustee shall give the notice of redemption in the
Company’s name and at the Company’s sole expense; provided, however, that the Company has delivered to the Trustee, at least five Business Days prior to the date on which such notice is to be given (unless a shorter notice shall be agreed
to in writing by the Trustee), an Officers’ Certificate requesting that the Trustee give such notice together with the notice to be given setting forth the information to be stated in such notice as provided in the preceding paragraph. 

  
 41 








 If any condition precedent provided for in the notice of redemption has not been satisfied
following delivery of such notice pursuant to this Section 3.03, the Company shall notify the Trustee in writing prior to the close of business two Business Days prior to the Redemption Date (or such shorter period as may be acceptable to the
Trustee). Upon receipt of such notice by the Trustee, (i) the notice of redemption shall be rescinded or delayed, and the redemption of the Notes shall be rescinded or delayed as provided in such notice; and (ii) the Trustee shall deliver
such notice to each Holder in the same manner in which the notice of redemption was given. 
 Section 3.04. Effect of Notice of
Redemption. Once the notice of redemption described in Section 3.03 is mailed (or delivered) and any conditions precedent to such redemption have been satisfied, Notes called for redemption become irrevocably due and payable on the Redemption
Date and at the Redemption Price, including any premium, plus interest accrued to the Redemption Date. Upon surrender to the Paying Agent, such Notes shall be paid at the Redemption Price, including any premium, plus interest accrued to the
Redemption Date; provided that (a) if the Redemption Date is after a Regular Record Date and on or prior to the Interest Payment Date, the accrued interest shall be payable to the Holder of the redeemed Notes registered on the relevant
Regular Record Date; and (b) if a Redemption Date is a Legal Holiday, payment shall be made on the next succeeding Business Day and no interest shall accrue for the period from such Redemption Date to such succeeding Business Day. Such notice,
if mailed (or delivered) in the manner provided in Section 3.03, shall be conclusively presumed to have been given whether or not the Holder receives such notice. 

Section 3.05. Deposit of Redemption Price. On or prior to [11:00 A.M.], New York City time, on each Redemption Date, the Company
shall deposit with the Paying Agent in immediately available funds money sufficient to pay the Redemption Price of, including premium, if any, and accrued interest on all Notes to be redeemed on that date other than Notes or portions thereof called
for redemption on that date which have been delivered by the Company to the Trustee for cancellation. 
 On and after any Redemption Date,
if money sufficient to pay the Redemption Price of, including premium, if any, and accrued interest on Notes called for redemption shall have been made available in accordance with the immediately preceding paragraph, the Notes called for redemption
will cease to accrue interest and the only right of the Holders of such Notes will be to receive payment of the Redemption Price of and, subject to Section 3.04(a), accrued and unpaid interest on such Notes to the Redemption Date. If any Note
surrendered for redemption shall not be so paid, interest will be paid, from, and including, the Redemption Date until such redemption payment is made, on the unpaid principal of the Note and any interest not paid on such unpaid principal, in each
case at the rate and in the manner provided in the Notes. 
 Section 3.06. Notes Redeemed in Part. If any Note is to be redeemed
in part only, the notice of redemption that relates to that Note will state the portion of the principal amount thereof that is to be redeemed. The Company will issue a new Note (or transfer by book-entry) in a principal amount equal to the
unredeemed portion of the original Note in the name of the Holder upon cancellation of the original Note. Notes called for redemption become due on the Redemption Date for such Notes, subject to the satisfaction of any conditions precedent. On and
after such Redemption Date, unless the Company defaults in payment of the Redemption Price on such Redemption Date, or any conditions precedent are not satisfied, interest ceases to accrue on the Notes or portions thereof called for such redemption.


  
 42 








 Section 3.07. Optional Redemption. Except as set forth below in this Section 3.07,
the Notes may not be redeemed at the option of the Company. 
 (a) At any time or from time to time on or after February 1, 2023, the
Company, at its option, may redeem the Notes, in whole or in part, at the Redemption Prices (expressed as percentages of principal amount) set forth below, plus accrued and unpaid interest thereon, if any, to the Redemption Date, if redeemed during
the 12-month period beginning on February 1 of the years indicated below (subject to the rights of Holders of record on the relevant Regular Record Date to receive interest due on the relevant Interest Payment Date if the Notes have not been
redeemed prior to such Regular Record Date):

accrued and unpaid interest thereon, if any, to the Redemption Date (subject to the rights of Holders of record on the relevant Regular Record Date to receive interest due on the relevant Interest Payment Date if the Notes have not been redeemed
prior to such Regular Record Date); provided that: 
 (i) at least 65% of the aggregate principal amount of Notes
issued under this Indenture (excluding Notes held by the Company and its Subsidiaries) remains outstanding immediately after the occurrence of such redemption; and 

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

Redemption Price equal to 100% of the principal amount thereof, plus the Applicable Premium as of, and accrued and unpaid interest thereon, if any, to, the Redemption Date (a “Make-Whole Redemption Date”) (subject to the rights of
Holders of record on the relevant Regular Record Date to receive interest due on the relevant Interest Payment Date if the Notes have not been redeemed prior to such Regular Record Date). Promptly after the determination thereof, the Company shall
give the Trustee notice of the redemption price provided for in this Section 3.07(c), and the Trustee shall not be responsible for such calculation.

COVENANTS 

Section 4.01. Payment of Principal, Premium and Interest. 

(a) The Company agrees to pay the principal of (and premium, if any) and interest on the Notes on the dates and in the manner provided in the
Notes and this Indenture. Not later than 11:00 A.M. (New York City time) on the due date of any principal of or interest on any Notes, or any redemption or purchase price of the Notes, the Company will deposit with the Trustee (or Paying Agent)
money in immediately available funds sufficient to pay such amounts; provided that if the Company or any Affiliate of the Company is acting as Paying Agent, it will, on or before each due date, segregate and hold in a separate trust fund for
the benefit of the Holders a sum of money sufficient to pay such amounts until paid to such Holders or otherwise disposed of as provided in this Indenture. In each case the Company will promptly notify the Trustee of its compliance with this
paragraph. 
 (b) An installment of principal or interest will be considered paid on the date due if the Trustee (or Paying Agent, other than
the Company or any Affiliate of the Company) holds on that date money designated for and sufficient to pay the installment. If the Company or any Affiliate of the Company acts as Paying Agent, an installment of principal or interest will be
considered paid on the due date only if paid to the Holders. 
 (c) The Company agrees to pay interest on overdue principal, and , to the
extent lawful, overdue installments of interest at the rate per annum specified in the Notes and Section 2.13. 
 (d) Payments in
respect of the Notes represented by the Global Notes are to be made by wire transfer of immediately available funds to the accounts specified by the Holders of the Global Notes. With respect to Certificated Notes, the Company will make all payments
by wire transfer of immediately available funds to the accounts specified by the Holders thereof or, if no such account is specified, by mailing a check to each Holder’s registered address. 

Section 4.02. Maintenance of Office or Agency. The Company will maintain in the United States of America for Notes an office or
agency where Notes may be presented or surrendered for payment, where Notes may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Company in respect of the Notes and this Indenture may be served.
The Company will 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, and the Company hereby appoints the Trustee as its agent to receive all such presentations,
surrenders, notices and demands. 

  
 44 








 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 each Place of Payment for Notes for such purposes. The Company will 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. 
 Section 4.03. Reports to Holders. 

(a) Notwithstanding that the Company may not be subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, the
Company will file with the Commission and provide the Trustee with such annual and quarterly reports and such information, documents and other reports as are specified in Sections 13 and 15(d) of the Exchange Act and applicable to a U.S. corporation
subject to such Sections, such information, documents and reports to be so filed and provided at the times specified for the filing of such information, documents and reports under such Sections; provided, however, that (a) the
Company will not be required to provide the Trustee with any such information, documents and reports that are filed with the Commission and (b) the Company will not be so obligated to file such information, documents and reports with the
Commission if the Commission does not permit such filings; provided further, however, that if the Commission does not permit such filings, the Company will be required to provide to the Trustee any such information, documents or
reports that are not so filed at the times specified for such filings under such Sections. The Trustee shall have no responsibility to determine if any such filing has occurred. Delivery of the reports, information and documents in accordance with
this paragraph shall satisfy the Company’s obligation to make such delivery, but, in the case of the Trustee, such delivery shall be for informational purposes only, and the Trustee’s receipt of such reports, information and documents
shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants (as to which the Trustee is entitled to conclusively
rely on an Officers’ Certificate). 
 (b) Notwithstanding anything herein to the contrary, in the event that the Company fails to comply
with its obligation to file or provide such information, documents and reports as required hereunder, the Company will be deemed to have cured such Default for purposes of Section 6.01(d) upon the filing or provision of all such information,
documents and reports required hereunder prior to the expiration of 60 days after written notice to the Company of such failure from the Trustee or the Holders of at least 25% of the principal amount of the outstanding Notes (with a copy to the
Trustee). 
 (c) To the extent not satisfied by the foregoing, for so long as any of the Notes remain outstanding and constitute
“restricted securities” under Rule 144, the Company will furnish to the Holders of the Notes and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act. 

(d) The Company will comply with Section 314(a) of the Trust Indenture Act. 

  
 45 








 Section 4.04. Corporate Existence. The Company will do or cause to be done all things
necessary to preserve and keep in full force and effect its existence and the existence of each of its Restricted Subsidiaries in accordance with their respective organizational documents, and the material rights, licenses and franchises of the
Company and each Restricted Subsidiary; provided that the Company is not required to preserve any such right, license or franchise, or the existence of any Restricted Subsidiary, if the maintenance or preservation thereof is no longer
desirable in the conduct of the business of the Company and its Restricted Subsidiaries taken as a whole; and provided further that this Section 4.04 shall not prohibit any transaction otherwise permitted by Article 5. 

Section 4.05. Money for Notes Payments to Be Held in Trust. If the Company shall at any time act as its own Paying Agent with
respect to the Notes, it will, on or before each due date of the principal of (and premium, if any) or interest on any of the Notes, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay the principal
(and premium, if any) or interest so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided and will promptly notify the Trustee of its action or failure so to act. 

Whenever the Company shall have a Paying Agent for the Notes, it will, prior to [11:00 a.m.], New York City time, on each due date of the
principal of (and premium, if any) or interest on the Notes, deposit with the Paying Agent a sum sufficient to pay the principal (and premium, if any) or interest so becoming due, such sum to be held in trust for the benefit of the Persons entitled
to such principal, premium or interest, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of its action or failure so to act. 

The Company may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct the Paying Agent to pay, to the Trustee all sums held in trust by the Company or the Paying Agent, such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by the Company or the Paying
Agent; and, upon such payment by the Paying Agent to the Trustee, the Paying Agent shall be released from all further liability with respect to such money. 

Any money deposited with the Trustee or the Paying Agent, or then held by the Company, in trust for the payment of the principal of (and
premium, if any) or interest on the Notes and remaining unclaimed for three years after such principal (and premium, if any) or interest has become due and payable shall be paid to the Company on Company Order, or (if then held by the Company) shall
be discharged from such trust; and the Holder of such Note shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or the Paying Agent with respect to such trust money, and
all liability of the Company as trustee thereof, shall thereupon cease. 
 Section 4.06. Payment of Taxes and Other Claims. The
Company will pay or discharge or cause to be paid or discharged, before the same shall become delinquent, (a) all material taxes, assessments and governmental charges levied or imposed upon the Company or any Restricted Subsidiary or upon the
income, profits or property of the Company or any Restricted Subsidiary, and (b) all lawful claims against the Company or any Restricted Subsidiary for labor, materials and supplies, which in the case of either clause (a) or (b) of this Section
4.06, if unpaid, might by 

  
 46 








 
law become a lien upon a Property; provided, however, that neither the Company nor any Restricted Subsidiary shall be required to pay or discharge or cause to be paid or discharged
any such tax, assessment, charge or claim (i) whose amount, applicability or validity is being contested in good faith by appropriate proceedings or (ii) where such failure to pay or discharge such tax, assessment, charge or claim would
not have a material adverse effect on the financial position, stockholders’ equity or results of operations of the Company and its Subsidiaries, taken as a whole. 

Section 4.07. Limitation on Liens. 

(a) Except as provided in Section 4.11 hereof, the Company will not, and will not permit any Subsidiary Guarantor to, directly or
indirectly, Incur or permit to exist any Lien of any nature whatsoever on any of its Principal Personal or Real Property (including Capital Stock of a Subsidiary Guarantor), whether owned at the Issue Date or thereafter acquired, securing any
Indebtedness for borrowed money of the Company or any Subsidiary Guarantor on any of its Principal Personal or Real Property (whether owned at the Issue Date or thereafter acquired), other than Permitted Liens, without effectively providing that the
Notes shall be secured equally and ratably with (or prior to) the obligations so secured on the same property for so long as such obligations are so secured. 

(b) Any Lien on any Principal Personal or Real Property created for the benefit of the Holders pursuant to Section 4.07(a) shall be deemed
automatically and unconditionally released and discharged upon the release and discharge of all Liens on the same Principal Personal or Real Property (other than Permitted Liens and Liens incurred in compliance with Section 4.11 hereof). 

(c) The expansion of Liens by virtue of the following shall not be deemed to be an incurrence of Liens for the purposes of this
Section 4.07: (i) amortization of debt discount or the accretion of principal with respect to a non-interest bearing or other discount security; (ii) the payment of regularly scheduled interest in the form of additional Indebtedness
of the same instrument or the payment of regularly scheduled dividends on Capital Stock in the form of additional Capital Stock of the same class and with the same terms; (iii) changes in value of Indebtedness attributable to movement in the
mark-to-market valuation thereof; (iv) the obligation to pay a premium in respect of Indebtedness arising in connection with the issuance of a notice of redemption or making of a mandatory offer to repurchase such Indebtedness and
(v) Indebtedness incurred solely as a result of fluctuations in the exchange rate of currencies. 
 (d) For purposes of determining
compliance with this Section 4.07, (x) a Lien need not be incurred solely by reference to one category of Permitted Liens but may be incurred under any combination of such categories (including in part under one such category and in part
under any other such category) and (y) in the event that a Lien (or any portion thereof) meets the criteria of one or more of such categories of Permitted Liens or may be incurred in compliance with Section 4.11 hereof, the Company shall,
in its sole discretion, classify or may subsequently reclassify at any time such Lien (or any portion thereof) in any manner that complies with this covenant (including by complying with Section 4.11 hereof) and the definition of Permitted
Liens. 

  
 47 








 Section 4.08. Limitations on Sale and Lease-Back Transactions. Except as provided in
Section 4.11 hereof, the Company will not, and will not permit any Subsidiary Guarantor to, consummate any Sale and Lease-Back Transaction with respect to any Principal Personal or Real Property with another Person (other than with the Company
or a Subsidiary Guarantor) unless: 
 (a) the Company or such Subsidiary Guarantor could incur Indebtedness secured by a Lien on the property
to be leased without equally and ratably securing the Notes; 
 (b) the property leased pursuant to such arrangement is sold for a price at
least equal to such property’s fair value (as determined by the Company in good faith); or 
 (c) within 365 days of the effective date
of any such Sale and Lease-Back Transaction, the Company applies the Net Proceeds of the sale of the leased property, less the amount of Net Proceeds used to prepay, redeem or purchase the Notes, (i) to the prepayment or retirement of Funded
Debt of the Company and its Subsidiaries (which may include the Notes), (ii) to pay any Convertible Note Repayment Obligations; and/or (iii) the acquisition, construction or improvement of any property or assets. 

Section 4.09. Repurchase of Notes Upon a Change of Control Repurchase Event. 

(a) If a Change of Control Repurchase Event occurs, each Holder of Notes will have the right to require that the Company repurchase all or any
part (in minimum denominations of $2,000 and integral multiples of $1,000) of such Holder’s Notes pursuant to a Change of Control offer (a “Change of Control Offer”) on the terms set forth in this Indenture, except that the Company
shall not be obligated to repurchase the Notes pursuant to this Section 4.09 in the event that the Company has exercised the right to redeem all of the Notes as described in Section 3.07. In the Change of Control Offer, the Company will offer to
repurchase all of the Notes at a repurchase price (the “Change of Control Repurchase Price”) in cash in an amount equal to 101% of the principal amount of such Notes, plus accrued and unpaid interest, if any, to (but not including) the
date of repurchase (the “Change of Control Repurchase Date”) (subject to the rights of Holders of record on the relevant Regular Record Date to receive interest due on the relevant Interest Payment Date if the Notes have not been
repurchased prior to such Regular Record Date). The Change of Control Repurchase Date will be a date fixed by the Company to be a Business Day no earlier than 30 nor later than 60 days from the date notice of the Change of Control Offer is mailed
(or sent); provided that the Change of Control Repurchase Date may not occur prior to the effectiveness of the Change of Control. 

(b) Within 30 days after any Change of Control Repurchase Event or, at the Company’s option, prior to such Change of Control Repurchase
Event but after it is publicly announced (provided that a definitive agreement is in place for such Change of Control), the Company must notify the Trustee and give written notice of the Change of Control Repurchase Event to each Holder of
Notes, by first-class mail, postage prepaid (or electronic transmission in the case of Global Notes), at its address appearing in the Note Register. The notice must state, among other things: 

(i) that a Change of Control Repurchase Event has occurred or may occur and the date of such event; 

  
 48 








 (ii) the Change of Control Repurchase Price and the Change of Control Repurchase
Date; 
 (iii) that any Note not tendered will continue to accrue interest; 

(iv) that, unless the Company defaults in the payment of the Change of Control Repurchase Price, any Notes accepted for payment
pursuant to the Change of Control Offer shall cease to accrue interest on and after the Change of Control Repurchase Date; and 

(v) other procedures that a Holder of Notes must follow to accept a Change of Control Offer or to withdraw acceptance of the
Change of Control Offer. 
 (c) The Company will comply with the applicable tender offer rules, including Rule 14e-l under the Exchange Act,
and any other applicable securities laws or regulations in connection with a Change of Control Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 4.09, the Company will
comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.09 by virtue of its compliance with such securities laws or regulations. The Company will not be required to
make a Change of Control Offer upon a Change of Control Repurchase Event if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements described in this Indenture applicable to a
Change of Control Offer made by the Company and purchases all Notes validly surrendered and not withdrawn under such Change of Control Offer. 

(d) On the Change of Control Repurchase Date, the Company will, to the extent permitted by law (and, at its election, in the case of clause
(iii)(x) below): 
 (i) accept for payment all Notes issued by it or portions thereof properly tendered pursuant to the
Change of Control Offer; 
 (ii) deposit with the Paying Agent an amount equal to the aggregate Change of Control Repurchase
Price in respect of all Notes or portions thereof so tendered; and 
 (iii) deliver, or cause to be delivered, to the Trustee
(x) for cancellation the Notes so accepted and (y) an Officers’ Certificate stating that such Notes or portions thereof have been tendered to and purchased by the Company. 

(e) If Holders of not less than 90% in aggregate principal amount of the outstanding Notes validly tender and do not withdraw such Notes in a
Change of Control Offer and the Company, or any third party making a Change of Control Offer in lieu of the Company as described in the last sentence of subsection (c) of this Section 4.09, repurchases all of the Notes validly tendered and
not withdrawn by such Holders, the Company or such third party will have the right, upon not less than 30 days nor more than 60 days’ prior notice (provided that such notice is given not more than 30 days following such repurchase pursuant to
the Change of Control Offer described above), to redeem all Notes that remain outstanding following such repurchase at a price in cash equal to 101% of the aggregate principal amount thereof plus 

  
 49 








 
accrued and unpaid interest, if any, to, but excluding, the Redemption Date (subject to the rights of Holders of record on the relevant Regular Record Date to receive interest due on the relevant
Interest Payment Date if the Notes have not been redeemed prior to such Regular Record Date). 
 (f) The Company’s obligation to make an
offer to repurchase the Notes pursuant to this Section 4.09 may be waived or modified with the written consent of the Holders of a majority in principal amount of the Notes then outstanding in accordance with Article 8 of this Indenture. 

Section 4.10. Additional Guarantees. If the Company or any Wholly Owned Subsidiary of the Company (other than a Receivables Entity
or an Excluded Disregarded Entity) that is a Restricted Subsidiary acquires or creates another Wholly Owned Subsidiary that is a Restricted Subsidiary (other than a Subsidiary Guarantor, a Receivables Entity, an Excluded Disregarded Entity or an
Unrestricted Subsidiary) after the Issue Date that provides a guarantee of the Company’s obligations under any Credit Facility (including the Senior Secured Credit Facilities) with an aggregate principal or committed amount of at least
$250,000,000, then, within 60 days after such Restricted Subsidiary provides such guarantee, such newly acquired or created Restricted Subsidiary will execute a Supplemental Indenture providing for a Subsidiary Guarantee by such Restricted
Subsidiary; provided, that this Section 4.10 shall not be applicable to any guarantee of any Restricted Subsidiary that existed at the time such Person became a Restricted Subsidiary and was not incurred in connection with, or in
contemplation of, such Person becoming a Restricted Subsidiary. The Company may elect, in its sole discretion, to cause any Subsidiary that is not otherwise required to be a Subsidiary Guarantor to become a Subsidiary Guarantor, in which case such
Subsidiary shall not be required to comply with the 60-day period in this Section 4.10. 
 Notwithstanding the foregoing, a Subsidiary
Guarantee of a Subsidiary Guarantor will be automatically released: 
 (a) upon a sale or disposition of such Subsidiary in a transaction
that is not prohibited under this Indenture such that such Subsidiary ceases to be a Subsidiary; 
 (b) upon the designation of such
Subsidiary Guarantor as an Unrestricted Subsidiary in accordance with the terms of this Indenture; 
 (c) if the Company exercises its Legal
Defeasance option or Covenant Defeasance option as described in Article 9 or if the Company’s obligations under this Indenture are discharged in accordance with the terms of this Indenture; 

(d) upon the release or discharge of the guarantee by such Subsidiary Guarantor of Indebtedness under the Senior Secured Credit Facilities, in
the case of the Subsidiary Guarantees issued on the Issue Date, or the release or discharge of such other guarantee that resulted in the creation of such Subsidiary Guarantee, except, in each case, a discharge or release by or as a result of payment
under such guarantee (it being understood that a release subject to a contingent reinstatement is still a release, and that if any such guarantee is so reinstated, such Subsidiary Guarantee shall also be reinstated to the extent that such Subsidiary
Guarantor would then be required to provide a Subsidiary Guarantee pursuant to this Section 4.10); or 

  
 50 








 (e) as provided for under Article 8; 

Section 4.11. Exempted Transactions. 

(a) Notwithstanding the provisions of Sections 4.07 and 4.08 hereof, the Company and any Subsidiary Guarantor may also (1) create, incur
or assume any Lien upon any property, assets or revenues, or (2) consummate any Sale and Lease-Back Transaction if: (i) the aggregate outstanding principal amount of all Secured Indebtedness for borrowed money of the Company and the
Subsidiary Guarantors that is secured by Liens on any Principal Personal or Real Property plus (ii) the aggregate Attributable Indebtedness in respect of Sale and Lease-Back Transactions that are subject to the restrictions on Sale and
Lease-Back Transactions set forth in Section 4.08 hereof does not exceed an amount that would cause the Consolidated Senior Secured Debt Ratio for the Test Period immediately preceding the creation, incurrence or assumption of such a Lien or
consummation of such Sale and Lease-Back Transaction, as applicable, to be greater than 4.00 to 1.00, calculated on a pro forma basis after giving effect to the creation, incurrence or assumption of such Lien and/or such Attributable
Indebtedness in respect of Sale and Lease-Back Transactions that is subject to the restrictions on Sale and Lease-Back Transactions set forth in Section 4.08 hereof. The Company and any Subsidiary Guarantor may guarantee any Lien created,
incurred or assumed and any Sale and Lease-Back Transaction consummated, in each case, in compliance with this Section 4.11. 
 (b) In the
event any Lien is created, incurred or assumed or any Sale and Lease-Back Transaction is consummated, in each case, in reliance upon compliance with the Consolidated Senior Secured Debt Ratio set forth in Section 4.11(a) hereof concurrently
with the creation, incurrence or assumption of any Permitted Lien, then solely for purposes of calculating the Consolidated Senior Secured Debt Ratio at such time (but, for the avoidance of doubt, not in any subsequent calculation of the
Consolidated Senior Secured Debt Ratio at a subsequent time), the Consolidated Senior Secured Debt Ratio will be calculated without regard to the creation, incurrence or assumption of any such Permitted Lien. 

Section 4.12. Compliance Certificate. 

(a) The Company and each Guarantor shall deliver to the Trustee, within 120 calendar days after the end of each fiscal year, an Officers’
Certificate that need not comply with Section 11.05 as to the signing Officers’ knowledge of the Company’s and/or such Guarantor’s, as applicable, compliance with all applicable conditions and covenants contained in this
Indenture. For purposes of this Section 4.12(a), such compliance shall be determined without regard to any grace period or requirement of notice provided under this Indenture. Any notice required to be given under this Section 4.12(a)
shall be delivered to the Trustee at its Corporate Trust Office. 
 (b) So long as any of the Notes are outstanding, the Company will deliver
to the Trustee, forthwith upon any Officer becoming aware of any Default or Event of Default, an Officers’ Certificate specifying such Default or Event of Default and what action the Company is taking or proposes to take with respect thereto.


  
 51 








 Section 4.13. Stay, Extension and Usury Laws. 

The Company and each of the Guarantors covenants (to the extent that it may lawfully do so) that it will 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 and
each of the Guarantors (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein
granted to the Trustee, but will suffer and permit the execution of every such power as though no such law has been enacted. 

Section 4.14. Financial Calculations for Limited Condition Acquisitions. In connection with any Limited Condition Acquisition and
any related transactions (including any financing thereof), at the Company’s election, (a) compliance with any requirement relating to the absence of a Default or Event of Default may be determined as of the date a definitive agreement for
such Limited Condition Acquisition is entered into (the “effective date”) and not as of any later date as would otherwise be required under this Indenture, and (b) any calculation of the Consolidated Senior Secured Debt Ratio,
any amount based on a percentage of Total Assets, or any other determination under any basket or ratio under this Indenture, may be made as of such effective date and, to the extent so made, will not be required to be made at any later date as would
otherwise be required under this Indenture, giving pro forma effect to such Limited Condition Acquisition and any related transactions (including any Incurrence of Indebtedness and the use of proceeds thereof). If the Company makes such an
election, any subsequent calculation of any such ratio, percentage and/or basket (unless the definitive agreement for such Limited Condition Acquisition expires or is terminated without its consummation) shall be calculated on an equivalent pro
forma basis. As used herein, the term “Limited Condition Acquisition” means any acquisition by one or more of the Company and its Restricted Subsidiaries of any assets, business or Person or any other Investment not prohibited
by this Indenture whose consummation is not expressly conditioned on the availability of, or on obtaining, third party financing.

to the Company and the Trustee or (ii) such default or defaults have resulted in the acceleration of the maturity of such Indebtedness and such acceleration has not been rescinded or such Indebtedness repaid in full within 30 days of receipt of
notice of such acceleration to the Company and the Trustee given by the Trustee or the Holders of not less than 25.0% in principal amount of the outstanding Notes; 

(e) one or more judgments or orders that exceed $250.0 million in the aggregate (net of amounts covered by insurance or bonded) for the payment
of money have been entered by a court or courts of competent jurisdiction against the Company or any Significant Subsidiary and such judgment or judgments have not been satisfied, stayed, annulled or rescinded within 90 days after such judgment or
judgments became final and nonappealable; 
 (f) any Subsidiary Guarantee by a Significant Subsidiary shall for any reason cease to be, or
shall for any reason be held in any judicial proceeding not to be, or asserted in writing by any Subsidiary Guarantor or the Company not to be, in full force and effect and enforceable in accordance with its terms, except to the extent contemplated
by this Indenture and any such Subsidiary Guarantee, and any such Default continues for 10 days; 
 (g) the Company or any Significant
Subsidiary: 
 (i) commences a voluntary insolvency proceeding; 

(ii) consents to the entry of an order for relief against it in an involuntary insolvency proceeding or consents to its
dissolution or winding-up; 
 (iii) consents to the appointment of a Custodian of it or for any substantial part of its
property; 
 (iv) makes a general assignment for the benefit of its creditors; or 

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

provided, however, that the liquidation of any Restricted Subsidiary into another Restricted Subsidiary, other than as part of a credit reorganization,
shall not constitute an Event of Default under this Section 6.01(g); and 
 (h) a court of competent jurisdiction enters an order or
decree under any Bankruptcy Law that: 

  
 54 








 (i) is for relief against the Company or any Significant Subsidiary in an
involuntary insolvency proceeding; 
 (ii) appoints a Custodian of the Company or any Significant Subsidiary or for any
substantial part of their property; 
 (iii) orders the winding-up, liquidation or dissolution of the Company or any
Significant Subsidiary; 
 (iv) orders the presentation of any plan or arrangement, compromise or reorganization of the
Company or any Significant Subsidiary; or 
 (v) grants any similar relief under any foreign laws; 

and in each such case the order or decree remains unstayed and in effect for 60 consecutive days. 

The foregoing will constitute Events of Default whatever the reason for any such Event of Default and whether it is voluntary or involuntary
or is effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body. 

Section 6.02. Acceleration of Maturity; Rescission. If an Event of Default with respect to the Notes (other than an Event of
Default specified in Section 6.01(g) or Section 6.01(h) with respect to the Company) shall have occurred and be continuing, either the Trustee (if the Event of Default is known to the Responsible Officers of the Trustee) or the Holders of at least
25% in outstanding principal amount of the Notes may declare to be immediately due and payable, by notice in writing to the Company and the Trustee specifying (x) the Event of Default that occurred and is continuing and (y) that such
notice is an acceleration notice, the principal amount of all such Notes then outstanding, plus accrued but unpaid interest to the date of acceleration. If an Event of Default specified in Section 6.01(g) or Section 6.01(h) with respect to the
Company shall occur, such amount with respect to all the Notes shall become automatically due and payable immediately without any further action or notice. After any such acceleration, but before a judgment or decree based on acceleration is
obtained by the applicable Person, the Holders of a majority in principal amount of the Notes then outstanding may cancel such acceleration and its consequences if (i) the rescission would not conflict with any judgment or decree and
(ii) if all existing Events of Default have been cured or waived except nonpayment of principal that has become due solely because of the acceleration and all amounts owing to the Trustee have been paid. No such rescission shall affect any
subsequent Default or impair any right consequent thereto. 
 Section 6.03. Other Remedies. If an Event of Default occurs and is
continuing, the Trustee may pursue any available remedy by proceeding at law or in equity to collect the payment of principal of, or premium, if any, and interest on the Notes, as the case may be, or to enforce the performance of any provision of
the Notes, the Subsidiary Guarantees or this Indenture and may take any necessary action requested of it as Trustee to settle, compromise, adjust or otherwise conclude any proceedings to which it is a party. 

  
 55 








 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. Any such proceeding instituted by the Trustee may be brought in its own name and as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable
compensation, expenses, disbursements of the Trustee and its counsel, be for the ratable benefit of the Holders of the Notes in respect of which such judgment has been recovered. A delay or omission by the Trustee or any Holder 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. No remedy is exclusive of any other remedy. All available remedies are cumulative, to the
extent permitted by law. 
 Section 6.04. Waiver of Past Defaults and Events of Default. Provided the Notes are not then due and
payable by reason of a declaration of acceleration, the Holders of a majority in principal amount of the then outstanding Notes may on behalf of the Holders of all the affected Notes waive any past Default or Event of Default with respect to the
Notes and its consequences by providing written notice thereof to the Company and the Trustee, except a Default or Event of Default (1) in the payment of interest or premium, if any, on or the principal of any Note or (2) in respect of a
covenant or provision hereof which under this Indenture cannot be modified or amended without the consent of the Holder of each outstanding Note affected. In the case of any such waiver, the Company, the Trustee and the Holders of the Notes will be
restored to their former positions and rights under this Indenture, respectively, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; provided
that no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereto. 

Section 6.05. Control by Majority. The Holders of at least a majority in aggregate principal amount of the outstanding Notes may
direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee with respect to the Notes. However, the Trustee may refuse to follow any direction that
conflicts with law or this Indenture, that may involve the Trustee in personal liability, or that the Trustee determines in good faith may be unduly prejudicial to the rights of Holders of the affected Notes not joining in the giving of such
direction (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not any such directions are unduly prejudicial to such Holders), and may take any other action it deems proper that is not inconsistent with
any such direction received from Holders of the Notes. 
 Section 6.06. Limitation on Suits. No Holder of Notes will have any
right to institute any proceeding with respect to this Indenture, or for any remedy hereunder, unless: 
 (a) the Trustee has failed to
institute such proceeding for 60 days after the Holder has previously given to the Trustee written notice of a continuing Event of Default with respect to such Notes, 

(b) the Holders of at least 25% in aggregate principal amount of outstanding Notes have made a written request to the Trustee to institute such
proceeding as Trustee, and offered security or indemnity acceptable to the Trustee; and 

  
 56 








 (c) the Trustee has not received from the Holders of a majority in aggregate principal amount of
the outstanding Notes a direction that is inconsistent with such request. 
 However, the Holder of any Note will have an absolute and
unconditional right to receive payment of the principal of, and premium, if any, or interest on, such Note on or after the date or dates they are required to be paid as expressed in such Note and to institute suit for the enforcement of any such
payment. 
 Section 6.07. Rights of Holders to Receive Payment. Notwithstanding any other provision of this Indenture,
the contractual right of any Holder of a Note to receive payment of the principal of or premium, if any, or interest, if any, on such Note (including in connection with an offer to purchase) or to bring suit for the enforcement of any such payment,
on or after the due date expressed in the Notes shall not be impaired or affected without the consent of such Holder. 

Section 6.08. Collection Suit by Trustee. If an Event of Default in payment of principal, premium or interest specified in Section
6.01(a) or Section 6.01(b) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company (or any other obligor on the Notes) for the whole amount of unpaid principal and accrued
interest remaining unpaid, 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 may 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 any other amounts due the Trustee under Section
7.06) 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, unless prohibited by law, shall be entitled and empowered to collect and receive any monies
or other property payable or deliverable on any such claims and to distribute the same after deduction of its charges and expenses to the extent that any such charges and expenses are not paid out of the estate in any such proceedings 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 7.06. 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 7.06 hereof out of the estate in any such proceeding, shall be unpaid 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. The Trustee may, on behalf of the Holders, vote for the election of a trustee in bankruptcy or similar official and be a member of a creditors’ committee or other similar committee. 

  
 57 








 Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or
accept or adopt on behalf of any Holder any plan or reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such
proceedings. All rights of action and claims under this Indenture or the Notes may be prosecuted and enforced by the Trustee without the possession of any of the Notes thereof in any proceeding relating thereto, and any such proceeding instituted by
the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and
counsel, be for the ratable benefit of the Holders in respect of which such judgment has been recovered. 
 Section 6.10.
Priorities. Any money or property collected by the Trustee pursuant to this Article 6 shall be applied in the following order: 

FIRST: to the Trustee (including any predecessor Trustee) for amounts due under Section 7.06; 

SECOND: to Holders for amounts due and unpaid on the affected Notes for principal, premium, if any, and interest as to each, ratably, without
preference or priority of any kind, according to the amounts due and payable on the affected Notes; and 
 THIRD: to the Company. 

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

Section 6.12. Delay or Omission Not Waiver. No delay or omission of the Trustee or of any Holder of any Notes to exercise
any right or remedy occurring upon an Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article 6 or by law to the Trustee or
to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be.

Indenture but, in the case of any such certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to
the requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts, statements, opinions or conclusions stated therein).

it against such risk or liability is not reasonably assured to it. The Trustee shall not be required to give any bond or surety in respect of the performance of its powers or duties hereunder.

resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document, but the Trustee, in its discretion, may make such further
inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books records, and premises of the Company, personally or
by agent or attorney at the sole cost of the Company and shall incur no liability or additional liability of any kind by reason of such inquiry or investigation.

other event has occurred or notify the Holders of any such event.

Holders of the Notes notice of each Default or Event of Default known to the Trustee, by transmitting such notice to Holders at their addresses as the same shall then appear on the Note Register, unless such Default shall have been cured or waived
before the giving of such notice. Except in the case of a Default or Event of Default in payment of the principal of, premium, if any, or interest on any of the Notes when and as the same shall become payable, or to make any sinking fund payment as

advances incurred or made by them in connection with the Trustee’s duties under this Indenture, including the reasonable compensation, disbursements and expenses of the Trustee’s agents and external counsel, except any such expense,

employees and any predecessor Trustee for, and hold each of them harmless against, any and all loss, damage, claim, liability, fees, costs, or expense, including, without limitation, reasonable attorneys’ fees and expenses incurred by each of

with any action, claim or suit brought to enforce the Trustee’s right to compensation, reimbursement or indemnification. The Trustee or Agent shall notify the Company in writing promptly of any claim of which a Responsible Officer of the
Trustee has actual knowledge asserted against the Trustee or Agent for which it may seek indemnity; provided that the failure by the Trustee or Agent to so notify the Company shall not relieve the Company of its obligations hereunder. In the
event that a conflict of interest exists or potential harm to the Trustee’s business exists, the Trustee may have separate counsel, which counsel must be reasonably acceptable to the Company and the Company shall pay the reasonable fees and
expenses of such counsel. 
 (c) Notwithstanding the foregoing, the Company need not reimburse the Trustee for any expense or indemnify it
against any loss or liability to have been incurred by the Trustee through its own willful misconduct or negligence as finally adjudicated by a court of competent jurisdiction.

any Bankruptcy Law.

appointment of a successor Trustee. 

  
 64

of Trust Indenture Act Section 310(b) may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. A successor Trustee shall mail or send notice of its succession to each Holder. Notwithstanding replacement of the Trustee pursuant to this

AMENDMENT, SUPPLEMENT AND WAIVER 

Section 8.01. Without Consent of Holders. The Company, the Subsidiary Guarantors and the Trustee may modify or amend this
Indenture without the consent of any Holder to:

of certificated Notes; 
 (3) comply with the requirements of Section 4.09 or Article 5, as set forth in an Officers’
Certificate; 
 (4) evidence and provide for the acceptance of appointment by a successor Trustee; 

  
 65 








 (5) make any change that would provide any additional rights or benefits to the
Holders of the Notes or that does not adversely affect the legal rights under this Indenture of any such Holder, as set forth in an Officers’ Certificate; 

(6) add covenants for the benefit of the Holders or to surrender any right or power conferred upon the Company or any
Subsidiary Guarantor, as set forth in an Officers’ Certificate; 
 (7) secure the Notes; 

(8) provide for the issuance of Additional Notes in accordance with the limitations set forth in this Indenture; 

(9) conform the text of this Indenture, the Notes or the Subsidiary Guarantees to any provision of the “Description of
Notes”, contained in the Offering Circular, as set forth in an Officers’ Certificate; 
 (10) allow any Subsidiary
Guarantor to execute a Supplemental Indenture; provided, that any supplemental indenture for the purpose of permitting any existing or future Subsidiary to provide a Subsidiary Guarantee may be signed by the Company, the Subsidiary providing
the Guarantee and the Trustee; and 
 (11) provide for the release of a Guarantee of the Notes by a Restricted Subsidiary of
the Company where such release is otherwise not prohibited under this Indenture and would not result in a Default or an Event of Default. 

Section 8.02. With Consent of Holders. 

(a) The Company, the Subsidiary Guarantors and the Trustee may modify or amend this Indenture with the consent of the Holders of a majority in
aggregate principal amount of then outstanding Notes (including consents obtained in connection with a tender offer or exchange offer for Notes), and any past Default or compliance with any provisions of this Indenture may also be waived (except a
default in the payment of principal, premium or interest and a default under clause (b) of this Section 8.02) with the consent of the Holders of a majority in aggregate principal amount of then outstanding Notes. 

(b) However, no such modification or amendment may, without the consent of each Holder of Notes affected thereby: 

(1) change the due date of the principal of, or any installment of principal of or interest on, the Notes; 

(2) reduce the principal amount of, or any premium or interest rate on, the Notes; 

(3) change the place or currency of payment of principal of, or any premium or interest on, the Notes; 

  
 66 








 (4) reduce the amount payable upon the redemption of any Note or change the time
at which any Note may be redeemed, in each case as described under Section 3.07; 
 (5) release any Subsidiary Guarantor from
any of its obligations under its Subsidiary Guarantee or this Indenture otherwise than in accordance with the terms of this Indenture; 

(6) impair the right to institute suit for the enforcement of any payment on or with respect to the Notes, after the due date
thereof; or 
 (7) reduce the percentage in principal amount of the Notes then outstanding, the consent of whose Holders is
required for modification or amendment of this Indenture, for waiver of compliance with certain provisions of this Indenture or for waiver of certain Defaults. 

(c) Except as provided in Sections 6.02, 6.04 and 6.07, clause (b) of this Section 8.02 and the immediately succeeding sentence, the
Holders of a majority of the principal amount of then outstanding Notes may waive future compliance by the Company with any provision of this Indenture. The Holders of at least a majority in principal amount of then outstanding Notes may waive any
past Default under this Indenture, except a failure by the Company to pay the principal of, or any premium or interest on, any Notes or a provision that cannot be modified or amended without the consent of the Holders of all outstanding Notes. 

(d) In determining whether the Holders of the required principal amount of Notes have concurred in any direction, notice, waiver or consent,
Notes owned by the Company or any Subsidiary, or by any Affiliate of the Company or any Subsidiary, will be considered as though not outstanding, except that for the purposes of determining whether the Trustee will be protected in conclusively
relying on any such direction, notice, waiver or consent, only Notes that a Responsible Officer of the Trustee knows are so owned will be so disregarded. 

(e) It is not necessary for the consent of the Holders under this Section 8.02 to approve the particular form of any proposed amendment,
supplement or waiver, but it is sufficient if such consent approves the substance thereof. 
 (f) After an amendment that requires the
consent of the Holders of the Notes becomes effective, the Company shall mail or send to each registered Holder of the Notes at such Holder’s address appearing in the Note Register a notice briefly describing such amendment. However, the
failure to give such notice to all Holders of the Notes, or any defect therein, shall not impair or affect the validity of the amendment. 

(g) Upon the written request of the Company accompanied by a board resolution of the Board of Directors of the Company authorizing the
execution of any such supplemental indenture pursuant to Section 8.01 or this Section 8.02, and upon the receipt by the Trustee of evidence reasonably satisfactory to the Trustee of the consent of the Holders in the case of a supplemental
indenture pursuant to Section 8.02(a), and upon receipt by the Trustee of the documents described in Section 8.05, the Trustee shall join with the Company in the execution of such supplemental indenture unless such supplemental indenture
adversely affects the Trustee’s own rights, duties or immunities under this Indenture, in which case the Trustee may, but shall not be obligated to, enter into such supplemental indenture. 

  
 67 








 Section 8.03. Revocation and Effect of Consents. After an amendment,
supplement, waiver or other action becomes effective, a consent to it by a Holder of a Note is a continuing consent conclusive and binding upon such Holder and every subsequent Holder of the same Note or portion thereof, and of any Note issued upon
the transfer thereof or in exchange therefor or in place thereof, even if notation of the consent is not made on any such Note. However, subject to Section 11.02(d), any such Holder of a Note or subsequent Holder of a Note may revoke the consent as
to its Note if the Trustee receives written notice of revocation before the date the amendment, supplement or waiver becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every
Holder. 
 The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to
consent to any amendment, supplement, or waiver in accordance with Section 11.02(d). 
 Section 8.04. Notation on or Exchange
of Notes. If an amendment, supplement, or waiver changes the terms of a Note, the Trustee (in accordance with the specific written direction of the Company) shall request the Holder of the Note (in accordance with the specific written direction
of the Company) to deliver it to the Trustee. In such case, the Trustee shall place an appropriate notation on the Note about the changed terms and return it to the Holder. Alternatively, if the Company or the Trustee so determines, the Company in
exchange for the Note shall issue and the Trustee shall authenticate a new Note that reflects the changed terms. 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 8.05. Trustee to Sign Amendments, Etc. The Trustee shall sign any amendment, supplement or
waiver authorized pursuant to this Article 8 if the amendment, supplement or waiver does not affect the rights, duties, liabilities or immunities of the Trustee. If it does affect the rights, duties, liabilities or immunities of the Trustee, the
Trustee may, but need not, sign such amendment, supplement or waiver. In signing or refusing to sign such amendment, supplement or waiver the Trustee shall be entitled to receive and, subject to Section 7.01, shall be fully protected in relying upon
an Officers’ Certificate and an Opinion of Counsel stating, in addition to the matters required by Section 11.04, that such amendment, supplement or waiver is authorized or permitted by this Indenture and constitutes the legal, valid and
binding obligation of the Company and the Subsidiary Guarantors; provided that the legal counsel delivering such Opinion of Counsel may rely on matters of fact set forth in one or more Officers’ Certificates of the Company.

 ARTICLE 9 

SATISFACTION AND DISCHARGE OF INDENTURE; DEFEASANCE

 Section 9.01. Satisfaction and Discharge of Liability on Notes; Defeasance. 

(a) This Indenture will be discharged and will cease to be of further effect (except as to rights of registration of transfer or exchange of
Notes which shall survive until all Notes have been canceled) as to all outstanding Notes when: 
 (1) either: 

(A) all the Notes that have been authenticated and delivered (except lost, stolen or destroyed Notes which have been replaced
or paid and Notes for whose payment money has been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from this trust) have been delivered to the Trustee for cancellation, or 

(B) all Notes not delivered to the Trustee for cancellation otherwise (i) have become due and payable, (ii) will
become due and payable, or may be called for redemption, within one year or (iii) have been called for redemption without conditions pursuant to the provisions described under Section 3.07 and, in any case, the Company or any Subsidiary
Guarantor has irrevocably deposited or caused to be deposited with the Trustee as trust funds, in trust solely for the benefit of the Holders of such Notes, U.S. legal tender, U.S. Government Obligations or a combination thereof, in such amounts as
will be sufficient (without consideration of any reinvestment of interest) in the opinion of a nationally recognized firm of independent public accountants selected by the Company and delivered to the Trustee if U.S. Government Obligations are
delivered, to pay and discharge the entire Indebtedness (including all principal and accrued interest) on the Notes not theretofore delivered to the Trustee for cancellation, 

(2) in respect of clause (a)(1)(B) of this Section 9.01, no Default or Event of Default has occurred and is continuing on the
date of the deposit (other than a Default or Event of Default resulting from borrowing funds to be applied to make such deposit (and any similar concurrent deposit relating to other Indebtedness) or the granting of Liens in connection therewith) and
the deposit will not result in a breach or violation of, or constitute a default under, any other instrument to which the Company or any Subsidiary Guarantor is a party or by which the Company or any Subsidiary Guarantor is bound (other than with
respect to the borrowing of funds to be applied concurrently to make the deposit required to effect such satisfaction and discharge (and any similar concurrent deposit relating to other Indebtedness) or the granting of Liens in connection
therewith), 
 (3) the Company or any Subsidiary Guarantor has paid all sums payable by it under this Indenture, and 

(4) the Company has delivered irrevocable instructions to the Trustee to apply the deposited money toward the payment of the
Notes at maturity or on the Redemption Date, as the case may be. 

  
 69 








 In addition, the Company must deliver to the Trustee an Officers’ Certificate and an Opinion
of Counsel stating that all conditions precedent to satisfaction and discharge have been complied with. 
 (b) The Company may, at its
option and at any time, elect to have its obligations and the obligations of the Subsidiary Guarantors discharged with respect to the outstanding Notes (“Legal Defeasance”). Legal Defeasance means that the Company and the Subsidiary
Guarantors shall be deemed to have paid and discharged the entire Indebtedness represented by the Notes and the related Subsidiary Guarantees, and this Indenture shall cease to be of further effect as to all outstanding Notes and the related
Subsidiary Guarantees, except as to: 
 (1) the rights of Holders of Notes issued under this Indenture to receive
payments in respect of the principal of, premium, if any, and interest on such Notes when such payments are due solely out of the trust created pursuant to this Indenture; 

(2) the Company’s obligations with respect to the Notes concerning issuing temporary Notes under Section 2.06,
registration of Notes under Section 2.09, mutilated, destroyed, lost or stolen Notes under Section 2.04, and the maintenance of an office or agency for payment under Section 2.03 and money for security payments held in trust under Section 4.05; 

(3) the rights, powers, trust, duties, and immunities of the Trustee, and the Company’s obligation in connection
therewith; and 
 (4) the applicable provisions of this Article 9. 

In addition, the Company may, at its option and at any time, elect to have its obligations and the obligations of the Subsidiary
Guarantors released with respect to (A) their respective obligations under Sections 4.03, 4.04 and 4.06 through 4.12, inclusive, with respect to the outstanding Notes and (B) the operation of Sections 6.01(c), (d), (e), (f), (g) or
(h) (only as such clauses (g) or (h) apply to Significant Subsidiaries) with respect to outstanding Notes (“Covenant Defeasance”) on and after the conditions in Section 9.02 with respect to Covenant Defeasance are
satisfied, and thereafter any omission to comply with such obligations shall not constitute a Default or Event of Default with respect to such Notes. The Company may exercise its Legal Defeasance option regardless of whether it previously exercised
Covenant Defeasance. 
 (c) If the Company exercises its Legal Defeasance option, payment of the Notes may not be accelerated because
of an Event of Default with respect thereto. 
 (d) Upon satisfaction of the conditions set forth herein and upon request of the Company, the
Trustee shall acknowledge in writing the discharge of those obligations that the Company terminates. 
 (e) Notwithstanding clauses (a) and
(b) of this Section 9.01, the Company’s obligations in Article 2 and Sections 4.01, 4.02, 7.06, 7.07, 9.05 and 9.06 shall survive with respect to the Notes until such time as the Notes have been paid in full. Thereafter, the Company’s
obligations in Sections 7.06, 7.07, 9.05 and 9.06 shall survive. 

  
 70 








 Section 9.02. Conditions to Defeasance. In order to exercise either Legal
Defeasance or Covenant Defeasance with respect to the Notes: 
 (a) the Company must irrevocably deposit with the Trustee, as trust
funds, in trust solely for the benefit of the Holders of the Notes, U.S. legal tender, U.S. Government Obligations or a combination thereof, in such amounts as will be sufficient (without consideration of any reinvestment of interest) in the opinion
of a nationally recognized firm of independent public accountants selected by the Company and delivered to the Trustee if U.S. Government Obligations are delivered, to pay the principal of and interest on the Notes on the stated date for payment or
on the Redemption Date of the principal or installment of principal of or interest on such Notes; 
 (b) in the case of Legal Defeasance, the
Company shall have delivered to the Trustee an Opinion of Counsel in the United States confirming that, subject to customary assumptions and exclusions: 

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

(2) since the Issue Date, there has been a change in the applicable U.S. Federal income tax law, 

in either case to the effect that, and based thereon this Opinion of Counsel shall confirm that, the Holders will not recognize income, gain or loss for U.S.
Federal income tax purposes as a result of the Legal Defeasance and will be subject to U.S. Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred; 

(c) in the case of Covenant Defeasance, the Company shall have delivered to the Trustee an Opinion of Counsel in the United States reasonably
acceptable to the Trustee confirming that, subject to customary assumptions and exclusions, the Holders will not recognize income, gain or loss for U.S. Federal income tax purposes as a result of such Covenant Defeasance and will be subject to U.S.
Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if the Covenant Defeasance had not occurred; 

(d) no Default or Event of Default (other than a Default or Event of Default resulting from the borrowing of funds to be applied to make such
deposit (and any similar concurrent deposit relating to other Indebtedness) or the granting of Liens in connection therewith) shall have occurred and be continuing on the date of such deposit; 

(e) such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a Default under this Indenture or
a default under any other material agreement or instrument to which the Company or any of its Restricted Subsidiaries is a party or by which the Company or any of its Restricted Subsidiaries is bound (other than any such Default or default resulting
solely from the borrowing of funds and the grant of any related liens to be applied to such deposit); 

  
 71 








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

(g) the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel in the United States (which Opinion
of Counsel may be subject to customary assumptions and exclusions) each stating that all conditions precedent provided for or relating to the Legal Defeasance or the Covenant Defeasance, as the case may be, have been complied with. 

If the funds deposited with the Trustee to effect Covenant Defeasance are insufficient to pay the principal of and interest on the Notes when
due, then the Company’s obligations and the obligations of Subsidiary Guarantors under this Indenture will be revived and no such defeasance will be deemed to have occurred. 

Section 9.03. Deposited Money and Government Obligations to be Held in Trust; Other Miscellaneous Provisions. All money and
Government Obligations (including the proceeds thereof) deposited with the Trustee pursuant to Section 9.02(a) in respect of the outstanding Notes shall be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and
this Indenture, to the payment, either directly or through any Paying Agent, to the Holders of such Notes, of all sums due and to become due thereon in respect of principal, premium, if any, and accrued interest, but such money need not be
segregated from other funds except to the extent required by law. 
 The Company shall pay and indemnify the Trustee against any tax,
fee or other charge imposed on or assessed against the Government Obligations deposited pursuant to Section 9.02(a) or the principal, premium, if any, and interest received in respect thereof other than any such tax, fee or other charge which by law
is for the account of the Holders of the outstanding Notes. 
 Anything in this Article 9 to the contrary notwithstanding, the Trustee shall
deliver or pay to the Company from time to time upon a request of the Company any money or Government Obligations held by it as provided in Section 9.02(a) which, in the opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance. 

Section 9.04. Reinstatement. If the Trustee or Paying Agent is unable to apply any money or Government Obligations in
accordance with Section 9.01 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s obligations under this
Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to this Article 9 until such time as the Trustee or Paying Agent is permitted to apply all such money or Government Obligations in accordance with
Section 9.01; provided that if the Company has made any payment of principal of, premium, if any, or accrued interest on any Notes because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders
of such Notes to receive such payment from the money or Government Obligations held by the Trustee or Paying Agent. 

  
 72 








 Section 9.05. Moneys Held by Paying Agent. In connection with the satisfaction
and discharge of this Indenture, all moneys then held by any Paying Agent under the provisions of this Indenture shall, upon written demand of the Company, be paid to the Trustee, or if sufficient moneys have been deposited pursuant to Section
9.02(a), to the Company upon a request of the Company, and thereupon the Paying Agent shall be released from all further liability with respect to such moneys. 

Section 9.06. Moneys Held by Trustee. Any moneys deposited with the Trustee or any Paying Agent or then held by the Company in
trust for the payment of the principal of, or premium, if any, or interest on any Note that are not applied but remain unclaimed by the Holder of such Note for two years after the date upon which the principal of, or premium, if any, or interest on
such Note shall have respectively become due and payable shall, subject to applicable abandoned property law, be repaid to the Company upon a request of the Company, or if such moneys are then held by the Company in trust, such moneys shall be
released from such trust; and the Holder of such Note entitled to receive such payment shall thereafter, as an unsecured general creditor, look only to the Company for the payment thereof, and all liability of the Trustee or the Paying Agent with
respect to such trust money shall thereupon cease. After payment to the Company or the release of any money held in trust by the Company, Holders entitled to the money must look only to the Company for payment as general creditors unless applicable
abandoned property law designates another Person. 
 ARTICLE 10 

GUARANTEES 

Section 10.01. Guarantee.  

(a) Each Subsidiary Guarantor, hereby jointly and severally, absolutely, unconditionally and irrevocably guarantees the Notes and obligations
of the Company hereunder and thereunder, including all Indenture Obligations, and guarantees to each Holder of a Note authenticated and delivered by the Trustee, and to the Trustee on behalf of such Holder, that (i) the principal of (and
premium, if any) and interest on the Notes will be paid in full when due, whether at Stated Maturity, by acceleration or otherwise (including, without limitation, the amount that would become due but for the operation of any automatic stay provision
of any Bankruptcy Law), together with interest on the overdue principal, if any, and interest on any overdue interest, to the extent lawful, and all other obligations of the Company to the Holders or the Trustee hereunder or thereunder will be paid
in full or performed, all in accordance with the terms hereof and thereof; and (ii) in case of any extension of time of payment or renewal of any Notes or of any such other obligations, the same will be paid in full when due or performed in
accordance with the terms of the extension or renewal, whether at Stated Maturity, by acceleration or otherwise, subject, however, in the case of clauses (i) and (ii) above, to the limitations set forth in Section 10.03. 

Each Subsidiary Guarantor hereby agrees that its obligations hereunder shall be unconditional, irrespective of the validity, regularity or
enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of Notes with respect to any provisions hereof or thereof, any release of any other Subsidiary Guarantor, the recovery
of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a Subsidiary Guarantor. 

  
 73 








 (b) Each Subsidiary Guarantor hereby waives (to the extent permitted by law) the benefits of
diligence, presentment, demand for payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company or any other Person, protest, notice and all demands
whatsoever and covenants that the Subsidiary Guarantee of such Subsidiary Guarantor shall not be discharged as to the Notes except by complete performance of the obligations contained in such Note, this Indenture and such Subsidiary Guarantee. Each
Subsidiary Guarantor acknowledges that the Subsidiary Guarantee is a guarantee of payment and not of collection. Each of the Subsidiary Guarantors hereby agrees that, in the event of a default in payment of principal (or premium, if any) or interest
on such Note, whether at its Stated Maturity, by acceleration, purchase or otherwise, legal proceedings may be instituted by the Trustee on behalf of, or by, the Holder of such Note, subject to the terms and conditions set forth in this Indenture,
directly against each of the Subsidiary Guarantors to enforce such Subsidiary Guarantor’s Subsidiary Guarantee without first proceeding against the Company or any other Subsidiary Guarantor. Each Subsidiary Guarantor agrees that if, after the
occurrence and during the continuance of an Event of Default, the Trustee or any of the Holders are prevented by applicable law from exercising their respective rights to accelerate the maturity of the Notes, to collect interest on the Notes, or to
enforce or exercise any other right or remedy with respect to the Notes, such Subsidiary Guarantor will pay to the Trustee for the account of the Holders, upon demand therefor, the amount that would otherwise have been due and payable had such
rights and remedies been permitted to be exercised by the Trustee or any of the Holders. 
 (c) If any Holder or the Trustee is required by
any court or otherwise to return to the Company or any Subsidiary Guarantor, or any custodian, trustee, liquidator or other similar official acting in relation to either the Company or any Subsidiary Guarantor, any amount paid by any of them to the
Trustee or such Holder, the Subsidiary Guarantee of each of the Subsidiary Guarantors, to the extent theretofore discharged, shall be reinstated in full force and effect. Each Subsidiary Guarantor further agrees that, as between each Subsidiary
Guarantor, on the one hand, and the Holders and the Trustee, on the other hand, (x) subject to this Article 10, the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 6 for the purposes of the Subsidiary
Guarantee of such Subsidiary Guarantor, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (y) in the event of any acceleration of such obligations as
provided in Article 6, such obligations (whether or not due and payable) shall forthwith become due and payable by each Subsidiary Guarantor for the purpose of the Subsidiary Guarantee of such Subsidiary Guarantor. 

(d) Each Subsidiary Guarantee shall remain in full force and effect and continue to be effective should any petition be filed by or against the
Company for liquidation or reorganization, should the Company become insolvent or make an assignment for the benefit of creditors or should a receiver or trustee be appointed for all or any significant part of the Company’s assets, and shall,
to the fullest extent permitted by law, continue to be effective or be reinstated, as the case may be, if at any time payment and performance of the Notes are, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be restored
or returned by any obligee on 

  
 74 








 
the Notes, whether as a “voidable preference”, “fraudulent transfer” or otherwise, all as though such payment or performance had not been made. In the event that any payment,
or any part thereof, is rescinded, reduced, restored or returned, the Notes shall, to the fullest extent permitted by law, be reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or returned. 

(e) The execution by each Subsidiary Guarantor of this Indenture or a Supplemental Indenture evidences the Subsidiary Guarantee of such
Subsidiary Guarantor, whether or not the person signing as an officer of such Subsidiary Guarantor still holds that office at the time of authentication of any Note. The delivery of any Note by the Trustee after authentication constitutes due
delivery of the Subsidiary Guarantee set forth in this Indenture on behalf of each Subsidiary Guarantor. 
 Section 10.02.
Severability. In case any provision of any Subsidiary Guarantee shall be invalid, illegal or unenforceable, the validity, legality, and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. 

Section 10.03. Limitation of Liability. Each Subsidiary Guarantor and by its acceptance hereof each Holder confirms that it
is the intention of all such parties that the guarantee by each such Subsidiary Guarantor pursuant to its Subsidiary Guarantee not constitute a fraudulent transfer or conveyance for purposes of the Bankruptcy Law, the Uniform Fraudulent Conveyance
Act, the Uniform Fraudulent Transfer Act or any similar U.S. Federal or state law or the provisions of its local law relating to fraudulent transfer or conveyance. To effectuate the foregoing intention, the Holders and each such Subsidiary Guarantor
hereby irrevocably agree that the obligations of such Subsidiary Guarantor under its Subsidiary Guarantee shall be limited to the maximum amount that, after giving effect to all other contingent and fixed liabilities of such Subsidiary Guarantor,
and after giving effect to any collections from or payments made by or on behalf of any other Subsidiary Guarantor in respect of the obligations of such other Subsidiary Guarantor under its Subsidiary Guarantee or pursuant to its contribution
obligations under this Indenture, will not result in the obligations of such Subsidiary Guarantor under its Subsidiary Guarantee constituting such fraudulent transfer or conveyance. 

Section 10.04. Contribution. In order to provide for just and equitable contribution among the Subsidiary Guarantors, the
Subsidiary Guarantors agree, inter se, that in the event any payment or distribution is made by any Subsidiary Guarantor under a Subsidiary Guarantee, such Subsidiary Guarantor will be entitled to a contribution from any other Subsidiary Guarantor
in a pro rata amount based on the net assets of each Subsidiary Guarantor determined in accordance with GAAP.  

Section 10.05. Subrogation. Each Subsidiary Guarantor shall be subrogated to all rights of Holders against the Company in
respect of any amounts paid by any Subsidiary Guarantor pursuant to the provisions of Section 10.01; provided, however, that if an Event of Default has occurred and is continuing, no Subsidiary Guarantor shall be entitled to enforce or
receive any payments arising out of, or based upon, such right of subrogation until all amounts then due and payable by the Company under this Indenture or the Notes shall have been paid in full. 

  
 75 








 Section 10.06. Reinstatement. Each Subsidiary Guarantor hereby agrees (and
each Person who becomes a Subsidiary Guarantor shall agree) that the Subsidiary Guarantee provided for in Section 10.01 shall continue to be effective or be reinstated, as the case may be, if at any time, payment, or any part thereof, of any
obligations or interest thereon is rescinded or must otherwise be restored by a Holder to the Company upon the bankruptcy or insolvency of the Company or any Subsidiary Guarantor. 

Section 10.07. Benefits Acknowledged. Each Subsidiary Guarantor acknowledges that it will receive direct and indirect
benefits from the financing arrangements contemplated by this Indenture and that its respective Subsidiary Guarantee and waiver pursuant to its respective Subsidiary Guarantee is knowingly made in contemplation of such benefits. 

ARTICLE 11 

MISCELLANEOUS 

Section 11.01. Trust Indenture Act of 1939. Except with respect to specific provisions of the Trust Indenture Act expressly
referenced in the provisions of this Indenture, or as otherwise required by the Trust Indenture Act, the Trust Indenture Act shall not be applicable to, and shall not govern, this Indenture and the Notes; provided that in the event this Indenture
has been qualified under the Trust Indenture Act, the Trust Indenture Act shall be applicable to, and shall govern, this Indenture and the Notes. 

Section 11.02. Holder Communications; Holder Actions. 

(a) The rights of Holders to communicate with other Holders with respect to this Indenture or the Notes are as provided by the Trust Indenture
Act. Neither the Company nor the Trustee will be held accountable by reason of any disclosure of information as to names and addresses of Holders made pursuant to the Trust Indenture Act, regardless of the source from which such information was
derived and such disclosure shall not be deemed to be a violation of existing law. 
 (b) Any request, demand, authorization,
direction, notice, consent to amendment, supplement or waiver or other action provided by this Indenture to be given or taken by a Holder (an “act”) may be evidenced by an instrument signed by the Holder delivered to the Trustee.
The fact and date of the execution of the instrument, or the authority of the person executing it, may be proved in any manner that the Trustee deems sufficient. The Trustee may make reasonable rules for action by or at a meeting of Holders, which
will be binding on all the Holders. 
 (c) Any act by the Holder of any Note binds that Holder and every subsequent Holder of a Note
that evidences the same debt as the Note of the acting Holder, even if no notation thereof appears on the Note. Subject to paragraph (d), a Holder may revoke an act as to its Notes, but only if the Trustee receives the notice of revocation before
the date the amendment or waiver or other consequence of the act becomes effective. 

  
 76 








 (d) The Company may, but is not obligated to, fix a record date (which need not be within the
time limits otherwise prescribed by Trust Indenture Act Section 316(c)) for the purpose of determining the Holders entitled to act with respect to any amendment or waiver or in any other regard, except that during the continuance of an Event of
Default, only the Trustee may set a record date as to notices of default, any declaration or acceleration or any other remedies or other consequences of the Event of Default. If a record date is fixed, those Persons that were Holders at such record

 Failure to mail a notice or communication to a Holder or any defect in it shall not affect its

If the Company mails a notice or communication to Holders, it will mail a copy to the Trustee and each Agent at the same time. 

In case by reason of the suspension of regular mail service, or by reason of any other cause, it shall be impossible to mail any notice as
required by this Indenture, then such method of notification as shall be made with the approval of the Trustee shall constitute a sufficient mailing of such notice. 

Section 11.04. Certificate and Opinion as to Conditions Precedent. 

Upon any request or application by the Company to the Trustee to take any action under this Indenture (other than the authentication and
delivery of the Initial Notes), the Company shall furnish to the Trustee:

statements set forth in Section 11.05) stating that, in the opinion of the signers, all conditions precedent, if any, provided for in this Indenture relating to the proposed action have been complied with; and 

  
 78

The Registrar or Paying Agent may make reasonable rules and set reasonable requirements for its functions. 

Section 11.07. No Personal Liability of Directors, Officers, Employees and Stockholders. No director, officer, employee or
stockholder of the Company or any of the Subsidiary Guarantors, as such, will have any liability for any of the Company’s or such Subsidiary Guarantor’s obligations under the Notes or this Indenture or for any claim based on, in respect
of, or by reason of, such obligations or their creation. Each Holder of Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes. 

Section 11.08. Governing Law; Waiver of Jury Trial. 

THE INTERNAL LAW OF THE STATE OF NEW YORK WILL GOVERN AND BE USED TO CONSTRUE THIS INDENTURE, THE NOTES AND THE SUBSIDIARY GUARANTEES, AND ANY
CLAIM, CONTROVERSY OR DISPUTE ARISING UNDER OR RELATED TO THIS INDENTURE, THE NOTES OR THE SUBSIDIARY GUARANTEES, WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER

delivery of this Indenture as to the parties hereto and may be used in lieu of the original Indenture for all purposes. Signatures of the parties hereto transmitted by facsimile or PDF shall be deemed to be their original signatures for all
purposes.  
 Section 11.13. Table of Contents, Headings, Etc. The Table of Contents and Headings of the Articles
and Sections of this Indenture have been inserted for convenience of reference only, are not to be considered a part of this Indenture and will in no way modify or restrict any of the terms or provisions hereof.

the U.S.A. PATRIOT Act, the Trustee, like all financial institutions and in order to help fight the funding of terrorism and money laundering, is required to obtain, verify, and record information that identifies each person or legal entity that
establishes a relationship or opens an account with the Trustee. The parties to this Indenture agree that they will provide the Trustee with such information as it may request in order for the Trustee to satisfy the requirements of the U.S.A.
PATRIOT Act.

The Company promises to pay, until the principal hereof is paid or made available for payment, interest on the principal amount set forth on
the face hereof at a rate of 4.625% per annum. Interest will accrue from, and including, the most recent date to which interest has been paid or, if no interest has been paid, from and including
[            ], 20[    ] to, but excluding, the date on which interest is paid. Interest shall be payable in arrears on each February 1 and August 1,
commencing on August 1, 2018, to the Holders of record of the Notes at the close of business on the January 15 or July 15 immediately preceding the Interest Payment Date). Interest will be computed on the basis of a 360-day year
composed of twelve 30-day months. 
 The Company will pay interest on overdue principal, premium, if any, and, to the extent lawful,
interest at a rate per annum that is 1% in excess of 4.625%. Interest not paid when due and any interest on principal, premium or interest not paid when due will be paid to the Persons that are Holders on a special record date, which will be the
15th day preceding the date fixed by the Company for the payment of such interest, whether or not such day is a Business Day. At least 15 days before a special record date, the Company will send to each Holder and to the Trustee a notice that sets
forth the special record date, the payment date and the amount of interest to be paid.

Initially, Wells Fargo Bank, National Association (the “Trustee”) will act as Paying Agent and Registrar. The Company may change any Paying Agent or Registrar without notice to the Holders. The Company or any of its
Subsidiaries may act as Paying Agent or Registrar, subject to certain exceptions. 
 3. Indenture; Subsidiary

 The Company issued the Notes under an Indenture dated as of January 19, 2018 (the
“Indenture”) among the Company, the Subsidiary Guarantors and the Trustee. This is one of the Notes of the Company issued under the Indenture. The terms of the Notes include those stated in the Indenture and those made part of the
Indenture by reference to the Trust Indenture Act. The Notes are subject to all such terms, and Holders are referred to the Indenture and the Trust Indenture Act for a statement of all such terms. To the extent permitted by applicable law, in the
event of any inconsistency between the terms of this Note and the terms of the Indenture, the terms of the Indenture will control. Capitalized and certain other terms used and not otherwise defined herein have the meanings set forth in the
Indenture.

6. Amendment, Supplement, Waiver, Etc. Subject to certain exceptions, the Indenture and the Notes may be amended, or default may
be waived, with the consent of the Holders of a majority in principal amount of the outstanding Notes. Without notice to or the consent of any Holder, the Company and the Trustee may amend or supplement the Indenture or the Notes to, among other
things, cure any ambiguity, defect or inconsistency. 
 7. Defaults and Remedies. If an Event of Default, as defined in
the Indenture, occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the Notes may declare all the Notes to be due and payable. If a bankruptcy or insolvency default with respect to the Company occurs and is
continuing, the Notes automatically become due and payable. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee may require indemnity satisfactory to it before it enforces the Indenture or the Notes.
Subject to certain limitations, Holders of a majority in principal amount of the Notes then outstanding may direct the Trustee in its exercise of remedies.
