Subsidiary (any such Investment, acquisition or designation, a “Purchase”), Consolidated EBITDA and Consolidated Interest Expense for such period shall be calculated after giving pro forma effect thereto (including the Incurrence of
any related Indebtedness) as if such Purchase occurred on the first day of such period, and 
 (5) if, since the beginning of

Purchase that would have required an adjustment pursuant to clause (2), (3) or (4) above if made by the Company or a Restricted Subsidiary since the beginning of such period, Consolidated EBITDA and Consolidated Interest Expense for such
period shall be calculated after giving pro forma effect thereto as if such Discharge, Sale or Purchase occurred on the first day of such period; 

provided that, for purposes of the foregoing calculations, (x) (in the event that the Company shall classify Indebtedness Incurred on the date of
determination as Incurred in part under Section 407(a) and in part under Section 407(b), as provided in Section 407(c)(iii)) any such pro forma calculation of Consolidated Interest Expense shall not give effect to

an authorized Officer of the Company; provided that with respect to cost savings or synergies relating to any Sale, Purchase or other transaction, the related actions are expected by the Company to be taken no later than 18 months after the
date of determination. If any Indebtedness bears a floating rate of interest and is being given pro forma effect, the interest expense on such Indebtedness shall be calculated as if the rate in effect on the date of determination had been the
applicable rate for the entire period (taking into account any Interest Rate Agreement applicable to such Indebtedness). If any Indebtedness bears, at the option of the Company or a Restricted Subsidiary, a rate of interest based on a prime or
similar rate, a eurocurrency interbank offered rate or other fixed or floating rate, and such Indebtedness is being given pro forma effect, the interest expense on such Indebtedness shall be calculated by applying such optional rate as the Company
or such Restricted Subsidiary may designate. If any Indebtedness that is being given pro forma effect was Incurred under a revolving credit facility, the interest expense on such Indebtedness shall be computed based upon the average daily balance of

contributed to the equity capital of the Company or its Restricted Subsidiaries), (vii) the amount of any loss attributable to non-controlling interests, (viii) all deferred financing costs written off and premiums paid in
connection with any early extinguishment of Hedging Obligations or other derivative

minus (iii) to the extent otherwise included in such interest expense referred to in clause (i) above, amortization or write-off of financing costs, in each case under clauses (i) through (iii) above as determined

Rate Agreements. 
 “Consolidated Net Income” means, for any period, the net income (loss) of the Company and its
Restricted Subsidiaries, determined on a Consolidated basis in accordance with GAAP and before any reduction in respect of Preferred Stock dividends; provided that, without duplication, there shall not be included in such Consolidated Net

Consolidated Net Income up to the aggregate amount of any dividend or distribution that was or that could have been made by such Restricted Subsidiary during such period to the Company or another Restricted Subsidiary (subject, in the case of a

(xii) expenses related to the conversion of various employee benefit programs in connection with the Transactions, and non-cash
compensation related expenses; 
 provided, further, that the exclusion of any item pursuant to the foregoing clauses (i) through

 In the case of any unusual or nonrecurring gain,
loss or charge not included in Consolidated Net Income pursuant to clause (iv) above in any determination thereof, the Company will deliver an Officer’s Certificate to the Trustee promptly after the date on which Consolidated Net Income is

(d) Any request, demand, authorization, direction, notice, consent, waiver or other action by the Holder of any Note shall bind the Holder of
every Note issued upon the transfer thereof or in exchange therefor or in lieu thereof, in respect of anything done, suffered or omitted to be done by the Trustee, the Company or any other obligor upon the Notes in reliance thereon, whether or not
notation of such action is made upon such Note. 
 (e) (i) The Company may set any day as a record date for the purpose of determining the
Holders of Outstanding Notes entitled to give, make or take any request, demand, authorization, direction, notice, consent, waiver or other action provided or permitted by this Indenture to be given, made or taken by Holders of Notes, provided that
the Company may not set a record date for, and the provisions of this paragraph shall not apply with respect to, the giving or making of any notice, declaration, request or direction referred to in the next paragraph. If any record date is set
pursuant to this paragraph, the Holders of Outstanding Notes on such record date (or their duly designated proxies), and no other Holders, shall be entitled to take the relevant action, whether or not such Persons remain Holders after such record
date; provided that no such action shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of Outstanding Notes on such record date. Nothing in this paragraph shall
be construed to prevent the Company from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any
Person be cancelled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite principal amount of Outstanding Notes on the date such action is taken. Promptly after any
record date is set pursuant to this paragraph, the Company, at its expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Trustee in writing and to each Holder of Notes
in the manner set forth in Section 110. 
 (ii) The Trustee may set any day as a record date for the purpose of determining the
Holders of Outstanding Notes entitled to join in the giving or making of (A) any Notice of Default, (B) any declaration of acceleration referred to in Section 602, (C) any request to institute
proceedings referred to in Section 607(ii) or (D) any direction referred to in Section 612, in each case with respect to Notes. If any record date is set pursuant to this paragraph, the Holders of Outstanding
Notes on such record date, and no other Holders, shall be entitled to join in such notice, declaration, request or direction, whether or not such Holders 

  
 52 








 
remain Holders after such record date; provided that no such action shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the requisite
principal amount of Outstanding Notes on such record date. Nothing in this paragraph shall be construed to prevent the Trustee from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph
(whereupon the record date previously set shall automatically and with no action by any Person be cancelled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite
principal amount of Outstanding Notes on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Trustee, at the Company’s expense, shall cause notice of such record date, the proposed action by
Holders and the applicable Expiration Date to be given to the Company in writing and to each Holder of Notes in the manner set forth in Section 110. 

(iii) With respect to any record date set pursuant to this Section 108, the party hereto that sets such record dates may designate
any day as the “Expiration Date” and from time to time may change the Expiration Date to any earlier or later day; provided that no such change shall be effective unless notice of the proposed new Expiration Date is given to
the Company or the Trustee, whichever such party is not setting a record date pursuant to this Section 108(e) in writing, and to each Holder of Notes in the manner set forth in Section 110, on or prior to the existing
Expiration Date. If an Expiration Date is not designated with respect to any record date set pursuant to this Section 108, the party hereto that set such record date shall be deemed to have initially designated the 180th day after such
record date as the Expiration Date with respect thereto, subject to its right to change the Expiration Date as provided in this paragraph. Notwithstanding the foregoing, no Expiration Date shall be later than the 180th day after the applicable
record date. 
 (iv) Without limiting the foregoing, a Holder entitled hereunder to take any action hereunder with regard to any particular
Note may do so with regard to all or any part of the principal amount of such Note or by one or more duly appointed agents each of which may do so pursuant to such appointment with regard to all or any part of such principal amount. 

(v) Without limiting the generality of the foregoing, a Holder, including the Depositary, that is the Holder of a Global Note, may make, give
or take, by a proxy or proxies duly appointed in writing, any request, demand, authorization, direction, notice, consent, waiver or other action provided in this Indenture to be made, given or taken by Holders, and the Depositary, as the Holder of a
Global Note, may provide its proxy or proxies to the beneficial owners of interests in any such Global Note through such depositary’s standing instructions and customary practices. 

(vi) The Company may fix a record date for the purpose of determining the persons who are beneficial owners of interests in any Global Note
held by the Depositary entitled under the procedures of such depositary to make, give or take, by a proxy or proxies duly appointed in writing, any request, demand, authorization, direction, notice, consent, waiver or other action provided in this
Indenture to be made, given or taken by Holders. If such a record 

  
 53 








 
date is fixed, the Holders on such record date or their duly appointed proxy or proxies, and only such persons, shall be entitled to make, give or take such request, demand, authorization
direction, notice consent, waiver or other action, whether or not such Holders remain Holders after such record date. No such request, demand, authorization, direction, notice, consent, waiver or other action shall be valid or effective if made,
given or taken more than 90 days after such record date. 
 Section 109. Notices, Etc., to Trustee and Company. Any request,
demand, authorization, direction, notice, consent, waiver or Act of Holders or other document provided or permitted by this Indenture to be made upon, given or furnished to, or filed with, 

(1) the Trustee by any Holder or by the Company or by any other obligor upon the Notes shall be sufficient for every purpose
hereunder if made, given, furnished or filed in writing to or with the Trustee at 246 Goose Lane, Suite 105, Guilford, Connecticut 06437, Attention: Corporate Trust Department (telephone: (203) 453-4130; telecopier: (203) 453-1183) or at

(3) the Company or the Trustee, by notice to the others, may designate additional or different addresses for subsequent notices
or communications. 
 Section 110. Notices to Holders; Waiver. Where this Indenture provides for notice to Holders of any event,
such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, first class postage prepaid, or by overnight air courier guaranteeing next day delivery, to each Holder affected by such event, at such
Holder’s address as it appears in the Note Register, not later than the latest date, and not earlier than the earliest date, prescribed for the giving of such notice. In any case where notice to Holders is given by mail, neither the failure to
mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. 

Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice,
either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in
reliance upon such waiver. 

  
 54 








 In case, by reason of the suspension of regular mail service, or by reason of any other cause, it
shall be impossible to mail notice of any event as required by any provision of this Indenture, then such notification as shall be made with the approval of the Trustee (such approval not to be unreasonably withheld) shall constitute a sufficient
notification for every purpose hereunder. 
 Notwithstanding any other provision of this Indenture or any Note, where this Indenture or any
Note provides for notice of any event (including any notice of redemption) to a Holder of a Global Note (whether by mail or otherwise), such notice shall be sufficiently given if given to the Depositary for such Note (or its designee) pursuant to
the customary procedures of such Depositary (including delivery by electronic mail). 
 Section 111. Effect of Headings and Table of
Contents. The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof. 

Section 112. Successors and Assigns. All covenants and agreements in this Indenture by the Company shall bind its respective
successors and assigns, whether so expressed or not. All agreements of the Trustee in this Indenture shall bind its successors. 

Section 113. Separability Clause. In case any provision in this Indenture or in the Notes 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 114. Benefits of Indenture. Nothing in this Indenture or in the Notes, express or implied, shall give to any Person, other
than the parties hereto and their successors hereunder, any Paying Agent and the Holders, any benefit or any legal or equitable right, remedy or claim under this Indenture. 

Section 115. GOVERNING LAW. THIS INDENTURE AND THE NOTES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE
STATE OF NEW YORK. THE TRUSTEE, THE COMPANY, ANY OTHER OBLIGOR IN RESPECT OF THE NOTES AND (BY THEIR ACCEPTANCE OF THE NOTES) THE HOLDERS AGREE TO SUBMIT TO THE JURISDICTION OF ANY UNITED STATES FEDERAL OR STATE COURT LOCATED IN THE BOROUGH OF
MANHATTAN, IN THE CITY OF NEW YORK IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE OR THE NOTES. 

  
 55 








 Section 116. Legal Holidays. In any case where any Interest Payment Date, Redemption
Date or Stated Maturity of any Note shall not be a Business Day at any Place of Payment, then (notwithstanding any other provision of this Indenture or of the Notes) payment of interest or principal and premium (if any) need not be made at such
Place of Payment on such date, but may be made on the next succeeding Business Day at such Place of Payment with the same force and effect as if made on the Interest Payment Date or Redemption Date, or at the Stated Maturity, and no interest shall
accrue on such payment for the intervening period. 
 Section 117. No Personal Liability of Directors, Officers, Employees,
Incorporators and Stockholders. No director, officer, employee, incorporator or stockholder of the Company, any Subsidiary Guarantor or any Subsidiary of any thereof shall have any liability for any obligation of the Company or any Subsidiary
Guarantor under this Indenture, the Notes or any Subsidiary Guarantee, or for any claim based on, in respect of, or by reason of, any such obligation or its creation. Each Noteholder, by accepting the Notes, waives and releases all such liability.
The waiver and release are part of the consideration for issuance of the Notes. 
 Section 118. Exhibits and Schedules. All
exhibits and schedules attached hereto are by this reference made a part hereof with the same effect as if herein set forth in full. 

Section 119. Counterparts. This Indenture may be executed in any number of counterparts, each of which shall be an original; but
such counterparts shall together constitute but one and the same instrument. The exchange of copies of this Indenture and of signature pages by facsimile transmission, PDF or other similar electronic transmission shall constitute effective execution
and delivery of this Indenture as to all the parties hereto and may be used in lieu of the original Indenture for all purposes. Signatures of the parties hereto transmitted by facsimile transmission, PDF or other similar electronic transmission
shall be deemed to be their original signatures for all purposes. 
 Section 120. Force Majeure. To the extent permitted by the
TIA, in no event shall the Trustee be responsible or liable for any failure or delay in the performance of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including, without limitation,
strikes, work stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications or computer (software and hardware)
services (it being understood that the Trustee shall use reasonable best efforts which are consistent with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances). 

  
 56 








 Section 121. Limited Condition Acquisition. In connection with any action being taken
in connection with a Limited Condition Acquisition and any related transactions (including any financing thereof), for purposes of determining compliance with any provision of this Indenture which requires that no Default, Event of Default or
specified Event of Default, as applicable, has occurred, is continuing or would result from any such action, as applicable, such condition shall, at the option of the Company, be deemed satisfied, so long as no Default, Event of Default or specified
Event of Default, as applicable, exists on the date a definitive agreement for such Limited Condition Acquisition is entered into. For the avoidance of doubt, if the Company has exercised its option under the first sentence of this
Section 121, and any Default or Event of Default occurs following the date the definitive agreements for the applicable Limited Condition Acquisition were entered into and prior to the consummation of such Limited Condition Acquisition,
any such Default or Event of Default shall be deemed to not have occurred or be continuing for purposes of determining whether any action being taken in connection with such Limited Condition Acquisition is permitted hereunder. 

In connection with any action being taken in connection with a Limited Condition Acquisition and any related transactions (including any
financing thereof), for purposes of: 
 (i) determining compliance with any provision of this Indenture which requires the calculation of the
Consolidated Coverage Ratio, the Consolidated Secured Leverage Ratio or the Consolidated Total Leverage Ratio; or 
 (ii) testing any basket
or ratio set forth in this Indenture (including baskets measured as a percentage of Four Quarter Consolidated EBITDA); 
 in each case, at the option of the
Company (the Company’s election to exercise such option in connection with any Limited Condition Acquisition, an “LCA Election”), the date of determination of whether any such action is permitted hereunder, shall be deemed to
be the date the definitive agreements for such Limited Condition Acquisition are entered into (the “LCA Test Date”), and if, after giving pro forma effect to the Limited Condition Acquisition and the other transactions to be entered
into in connection therewith (including any Incurrence of Indebtedness and the use of proceeds thereof) as if they had occurred at the beginning of the most recent four consecutive fiscal quarters ending prior to the LCA Test Date for which
consolidated financial statements of the Company are available, the Company could have taken such action on the relevant LCA Test Date in compliance with such ratio, basket and/or percentage, such ratio, basket and/or percentage shall be deemed to
have been complied with. For the avoidance of doubt, if the Company has made an LCA Election and any of the ratios, baskets, amounts and/or percentages for which compliance was determined or tested as of the LCA Test Date are exceeded as a result of
fluctuations in any such ratio, basket and/or percentage, including due to fluctuations in Consolidated EBITDA of the Company or the Person subject to such Limited Condition Acquisition or any applicable currency exchange rate, at or prior to the
consummation of the relevant transaction or action, such ratios, baskets, amounts and/or percentages will not be deemed to have been exceeded as a result of such fluctuations. If 

  
 57 








 
the Company has made an LCA Election for any Limited Condition Acquisition, then in connection with any subsequent calculation of any ratio or basket availability and/or percentage with respect
to the Incurrence of Indebtedness or Liens, or the making of Restricted Payments, mergers, the conveyance, lease or other transfer of all or substantially all of the assets of the Company or the designation of an Unrestricted Subsidiary on or
following the relevant LCA Test Date and prior to the earlier of the date on which such Limited Condition Acquisition is consummated or the definitive agreement for such Limited Condition Acquisition is terminated or expires without consummation of
such Limited Condition Acquisition, any such ratio, basket and/or percentage shall be calculated on a pro forma basis assuming such Limited Condition Acquisition and other transactions in connection therewith (including any Incurrence of
Indebtedness and the use of proceeds thereof) have been consummated.

the date or dates on which the principal of and premium, if any, on the Notes of the series is payable or the method of determination and/or extension of such date or dates, and the amount or amounts of such principal and premium, if any, payments
and methods of determination thereof; 
 (4) the rate or rates at which the Notes of the series shall bear interest, if any,
or the method of calculating and/or resetting such rate or rates of interest, the date or dates from which such interest shall accrue or the method by which such date or dates shall be determined, and the Interest Payment Dates on which any such
interest shall be payable; 
 (5) the period or periods within which, the price or prices at which, and other terms and
conditions upon which Notes of the series (i) may be redeemed, in whole or in part, at the option of the Company, if the Company is to have the option or (ii) shall be redeemed, in whole or in part, upon the occurrence of
specified events set forth herein, if the Notes shall be subject to a mandatory redemption provision; 

  
 64 








 (6) if other than the principal amount thereof, the portion of the principal
amount of Notes of the series that shall be payable upon declaration of acceleration of maturity thereof pursuant to Section 602 or the method by which such portion shall be determined; 

(7) in the case of any Notes, other than Initial Notes, any addition to or change in the Events of Default which apply to any

(8) in the case of any Notes, other than Initial Notes, any addition to or change in the covenants set forth in Articles IV
and V; and 
 (9) in the case of any Notes, other than Initial Notes, any addition to or change in the definitions in
Section 101 related to additions or changes contemplated by the foregoing clauses (7) and (8). 
 The form of the Notes of such series, as set
forth in Exhibit A, may be modified to reflect such matters as so established in such Notes Supplemental Indenture. 
 Such
matters may also be established in a Notes Supplemental Indenture for any Additional Notes issued hereunder that are to be of the same series as any Notes previously issued hereunder. Notes that have the same terms described in the foregoing clauses
(1) through (9) will be treated as the same series, unless otherwise designated by the Company. 
 Section 302.
Denominations. The Notes shall be issuable only in fully registered form, without coupons, and only in minimum denominations of $2,000 (the “Minimum Denomination”) and integral multiples of $1,000 in excess thereof. 

Section 303. Execution, Authentication and Delivery and Dating. The Notes shall be executed on behalf of the Company by one
Officer of the Company. The signature of any such Officer on the Notes may be manual or by facsimile. 
 Notes bearing the manual or
facsimile signature of an individual who was at any time an Officer of the Company shall bind the Company, notwithstanding that such individual has ceased to hold such office prior to the authentication and delivery of such Notes or did not hold
such office at the date of such Notes. 
 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; and the Trustee shall authenticate and deliver (i) Initial Notes for original issue in the aggregate principal amount not to exceed $550.0 million and
(ii) Additional Notes in one or 

  
 65 








 
more series (which may be of the same series as any Notes previously issued hereunder, or of a different series) from time to time for original issue in aggregate principal amounts specified by
the Company, in each case specified in clauses (i) and (ii) above, upon a written order of the Company in the form of an Officer’s Certificate of the Company (an “Authentication Order”). Such Officer’s
Certificate shall specify the amount of Notes to be authenticated and the date on which the Notes are to be authenticated, the “CUSIP”, “ISIN”, “Common Code” or other similar identification numbers of such Notes, if
any, whether the Notes are to be Initial Notes or Additional Notes and whether the Notes are to be issued as one or more Global Notes or Physical Notes and such other information as the Company may include or the Trustee may reasonably request. 

All Notes shall be dated the date of their authentication. 

No Note shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose, unless there appears on such Note a
certificate of authentication substantially in the form provided for herein executed by the Trustee by manual signature, and such certificate upon any Note shall be conclusive evidence, and the only evidence, that such Note has been duly
authenticated and delivered hereunder. 
 Section 304. Temporary Notes. Until definitive Notes are ready for delivery, the
Company may prepare and upon receipt of an Authentication Order the Trustee shall authenticate temporary Notes. Temporary Notes shall be substantially in the form of definitive Notes but may have variations that the Company considers appropriate for
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 shall be exchangeable for definitive Notes upon
surrender of the temporary Notes at the office or agency of the Company in a Place of Payment, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Notes, the Company shall execute and upon receipt of an
Authentication Order the Trustee shall authenticate and deliver in exchange therefor a like principal amount of definitive Notes of authorized denominations. Until so exchanged the temporary Notes shall in all respects be entitled to the same
benefits under this Indenture as definitive Notes of the same series and tenor. 
 Section 305. Note Registrar and Paying Agent.
The Company shall cause to be kept at the Corporate Trust Office of the Trustee a register (the register maintained in such office and in any other office or agency of the Company in a Place of Payment being herein sometimes collectively referred to
as the “Note Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Notes and of transfers of Notes. The Company may have one or more co-registrars. The
term “Note Registrar” includes any co-registrars. 
 The Company initially appoints the Trustee as “Note
Registrar” and “Paying Agent” in connection with the Notes, until such time as it has resigned or a successor has been 

  
 66 








 
appointed. The Company may have one or more additional paying agents, and the term “Paying Agent” shall include any additional Paying Agent. The Company may change the Paying Agent or
Note Registrar without prior notice to the Holders of Notes. The Company may enter into an appropriate agency agreement with any Note Registrar or Paying Agent not a party to this Indenture. Any such agency agreement shall implement the provisions
of this Indenture that relate to such agent. The Company shall notify the Trustee in writing of the name and address of any such agent. If the Company fails to appoint or maintain a Note Registrar or Paying Agent, the Trustee shall act as such and
shall be entitled to appropriate compensation therefor pursuant to Section 707. The Company or any wholly-owned Domestic Subsidiary of the Company may act as Paying Agent (except for purposes of Section 1103 or
Section 1205) or Note Registrar. 
 Upon surrender for transfer of any Note at the office or agency of the Company in a Place of
Payment, in compliance with all applicable requirements of this Indenture and applicable law, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes
of the same series, of any authorized denominations and of a like aggregate principal amount. 
 At the option of the Holder, Notes may be
exchanged for other Notes of the same series, of any authorized denominations and of a like tenor and aggregate principal amount, upon surrender of the Notes to be exchanged at such office or agency. Whenever any Notes are so surrendered for
exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Notes that the Holder making the exchange is entitled to receive. 

All Notes issued upon any transfer or exchange of Notes shall be the valid obligations of the Company, evidencing the same debt, and entitled
to the same benefits under this Indenture, as the Notes surrendered upon such transfer or exchange. 
 Every Note presented or surrendered
for transfer or exchange shall be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company duly executed, by the Holder thereof or such Holder’s attorney duly authorized in writing. 

No service charge shall be made for any registration, transfer or exchange of Notes, but the Company may require payment of a sum sufficient
to cover any transfer tax or other governmental charge that may be imposed in connection therewith. 
 The Company shall not be required
(i) to issue, transfer or exchange any Note during a period beginning at the opening of business 15 Business Days before the day of the sending of a notice of redemption (or purchase) of Notes selected for redemption (or purchase) under
Section 1004 and ending at the close of business on the day of such mailing, or (ii) to transfer or exchange any Note so selected for redemption (or purchase) in whole or in part. 

Section 306. Mutilated, Destroyed, Lost and Stolen Notes. If a mutilated Note is surrendered to the Note Registrar


  
 67 








 
or if the Holder of a Note claims that the Note has been lost, destroyed or wrongfully taken, the Company shall issue and the Trustee shall authenticate a replacement Note if the requirements of
Section 8-405 of the Uniform Commercial Code are met, such that the Holder (a) notifies the Company or the Trustee within a reasonable time after such Holder has notice of such loss, destruction or wrongful taking and the Note
Registrar does not register a transfer prior to receiving such notification, (b) makes such request to the Company or the Trustee prior to the Note being acquired by a protected purchaser as defined in
Section 8-303 of the Uniform Commercial Code and (c) satisfies any other reasonable requirements of the Company. If required by the Trustee or the Company, such Holder shall furnish an
indemnity bond sufficient in the judgment of (i) the Trustee to protect the Trustee and (ii) the Company to protect the Company, the Trustee, a Paying Agent and the Note Registrar, from any loss that any of them may suffer if
a Note is replaced. 
 In case any such mutilated, destroyed, lost or stolen Note has become or is about to become due and payable, the
Company in its discretion may, instead of issuing a new Note, pay such Note. 
 Upon the issuance of any new Note under this
Section 306, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected
therewith. 
 Every new Note issued pursuant to this Section 306 in lieu of any destroyed, lost or stolen Note shall constitute
an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Note shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and ratably with any and
all other Notes duly issued hereunder. 
 The provisions of this Section 306 are exclusive and shall preclude (to the extent
lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes. 

Section 307. Payment of Interest Rights Preserved. Interest on any Note that is payable, and is punctually paid or duly provided
for, on any Interest Payment Date shall be paid to the Person in whose name that Note (or one or more Predecessor Notes) is registered at the close of business on the Regular Record Date for such interest specified in Section 4 of the
applicable Notes Supplemental Indenture. 

  
 68 








 Unless otherwise specified for Notes of any series in the applicable Notes Supplemental
Indenture, as contemplated by Section 301, any interest on any Note that is payable, but is not punctually paid or duly provided for, on any Interest Payment Date (herein called “Defaulted Interest”) shall forthwith
cease to be payable to the registered Holder on the relevant Regular Record Date by virtue of having been such Holder; and such Defaulted Interest may be paid by the Company, at its election, as provided in clause (1) or clause (2) below:

 (1) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Notes (or their
respective Predecessor Notes) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner: The Company shall notify the Trustee and Paying Agent in writing
of the amount of Defaulted Interest proposed to be paid on each Note and the date of the proposed payment, and the Company shall deposit with the Trustee or Paying Agent an amount of money equal to the aggregate amount proposed to be paid in respect
of such Defaulted Interest or shall make arrangements reasonably satisfactory to the Trustee or Paying Agent for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons
entitled to such Defaulted Interest as provided in this clause (1). Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 nor less than 10 days prior to the date of the
proposed payment and not less than 10 days after the receipt by the Trustee and the Paying Agent of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of
the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be mailed, first class postage prepaid, to each Holder at such Holder’s address as it appears in the Note Register, not
less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Notes
(or their respective Predecessor Notes) are registered on such Special Record Date and shall no longer be payable pursuant to the following clause (2). 

(2) The Company may make payment of any Defaulted Interest in any other lawful manner not inconsistent with the requirements of
any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange. 
 Subject to the
foregoing provisions of this Section 307, each Note delivered under this Indenture upon transfer of or in exchange for or in lieu of any other Note shall carry the rights to interest accrued and unpaid, and to accrue, that were carried
by such other Note. 
 Section 308. Persons Deemed Owners. The Company, any Subsidiary Guarantor, the Trustee, the Paying Agent
and any agent of any of them may treat the Person in whose name any Note is registered as the owner of such Note for the purpose of receiving payment of principal of (and premium, if any), and (subject to Section 307) interest on, such
Note and for all other purposes whatsoever, whether or not such Note be overdue, and neither the Company, any Subsidiary Guarantor, the Trustee, the Paying Agent nor any agent of any of them shall be affected by notice to the contrary. 

  
 69 








 Section 309. Cancellation. All Notes surrendered for payment, redemption, transfer,
exchange or conversion shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and, if not already cancelled, shall be promptly cancelled by it. The Company may at any time deliver to the Trustee for cancellation any
Notes previously authenticated and delivered hereunder that the Company may have acquired in any manner whatsoever, and all Notes so delivered shall be promptly cancelled by the Trustee. No Notes shall be authenticated in lieu of or in exchange for
any Notes cancelled as provided in this Section 309, except as expressly permitted by this Indenture. All cancelled Notes held by the Trustee shall be disposed of by the Trustee in accordance with its customary procedures (subject to the
record retention requirements of the Exchange Act). 
 Section 310. Computation of Interest. Unless otherwise specified for
Notes of any series in the applicable Notes Supplemental Indenture, as contemplated by Section 301, interest on the Notes shall be computed on the basis of a 360-day year of twelve 30-day months. 

Section 311. CUSIP Numbers, ISINs, Etc. The Company in issuing the Notes may use “CUSIP” numbers, ISINs and “Common
Code” numbers (if then generally in use), and if so, the Trustee may use the CUSIP numbers, ISINs and “Common Code” numbers in notices of redemption or exchange as a convenience to Holders; provided, however, that any
such notice may state that no representation is made as to the correctness or accuracy of such numbers printed in the notice or on the Notes; that reliance may be placed only on the other identification numbers printed on the Notes; and that any
redemption shall not be affected by any defect in or omission of such numbers. 
 Section 312. Book-Entry Provisions for Global
Notes. (a) Each Global Note initially shall (i) be registered in the name of the Depositary for such Global Note or the nominee of such Depositary, in each case for credit to the account of an Agent Member, and
(ii) be delivered to the Trustee as custodian for such Depositary. None of the Company, any agent of the Company or the Trustee shall have any responsibility or liability for any aspect of the records relating to or payments made on
account of beneficial ownership interests of a Global Note, or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests. 

(b) Members of, or participants in, the Depositary (“Agent Members”) shall have no rights under this Indenture with respect to
any Global Note held on their behalf by the Depositary, or its custodian, or under such Global Notes. The Depositary may be treated by the Company, any other obligor upon the Notes, the Trustee and any agent of any of them as the absolute owner of
the Global Notes for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, any other obligor upon the Notes, the Trustee or any 

  
 70 








 
agent of any of them from giving effect to any written certification, proxy or other authorization furnished by the Depositary or impair, as between the Depositary and its Agent Members, the
operation of customary practices governing the exercise of the rights of a beneficial owner of any Note. The Holder of a Global Note may grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests
through Agent Members, to take any action that a Holder is entitled to take under this Indenture or the Notes. 
 (c) Transfers of a Global
Note shall be limited to transfers of such Global Note in whole, but, subject to the immediately succeeding sentence, not in part, to the Depositary, its successors or their respective nominees. Interests of beneficial owners in a Global Note may
not be transferred or exchanged for Physical Notes unless (i) the Company has consented thereto in writing, or such transfer or exchange is made pursuant to the next sentence, and (ii) such transfer or exchange is in
accordance with the applicable rules and procedures of the Depositary and the provisions of Section 305 and Section 313. Subject to the limitation on issuance of Physical Notes set forth in Section 313(3),
Physical Notes shall be transferred to all beneficial owners in exchange for their beneficial interests in the relevant Global Note, if (i) the Depositary notifies the Company at any time that it is unwilling or unable to continue as
Depositary for the Global Notes and a successor depositary is not appointed within 120 days; (ii) the Depositary ceases to be registered as a “Clearing Agency” under the Exchange Act and a successor depositary is not appointed
within 120 days; (iii) the Company, at its option, notifies the Trustee that it elects to cause the issuance of Physical Notes; or (iv) an Event of Default shall have occurred and be continuing with respect to the Notes and
the Trustee has received a written request from the Depositary to issue Physical Notes. 
 (d) In connection with any transfer or exchange of
a portion of the beneficial interest in any Global Note to beneficial owners for Physical Notes pursuant to Section 312(c), the Note Registrar shall record on its books and records the date and a decrease in the principal amount of such
Global Note in an amount equal to the beneficial interest in the Global Note being transferred, and the Company shall execute, and the Trustee shall authenticate and deliver, one or more Physical Notes of like tenor and principal amount of
authorized denominations. 
 (e) In connection with a transfer of an entire Global Note to beneficial owners for Physical Notes pursuant to
Section 312(c), the applicable Global Note shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall execute, and the Trustee shall authenticate and deliver, to each beneficial owner identified by the
Depositary, in exchange for its beneficial interest in the applicable Global Note, an equal aggregate principal amount of Rule 144A Physical Notes (in the case of any Rule 144A Global Note) or Regulation S Physical Notes (in the case of any
Regulation S Global Note), as the case may be, of authorized denominations. 
 (f) The transfer and exchange of a Global Note or beneficial
interests therein shall be effected through the Depositary, in accordance with this Indenture (including applicable restrictions on transfer set forth in Section 313) and the procedures therefor of the Depositary. Any beneficial interest
in one of the Global Notes that is transferred to a Person who takes delivery in the form of an interest in a different Global Note will, upon transfer, cease to be an 

  
 71 








 
interest in such Global Note and become an interest in the other Global Note and, accordingly, will thereafter be subject to all transfer restrictions, if any, and other procedures applicable to
beneficial interests in such other Global Note for as long as it remains such an interest. A transferor of a beneficial interest in a Global Note shall deliver to the Note Registrar a written order given in accordance with the Depositary’s
procedures containing information regarding the participant account of the Depositary to be credited with a beneficial interest in the relevant Global Note. Subject to Section 313, the Note Registrar shall, in accordance with such
instructions, instruct the Depositary to credit to the account of the Person specified in such instructions a beneficial interest in such Global Note and to debit the account of the Person making the transfer the beneficial interest in the Global
Note being transferred. 
 (g) Any Physical Note delivered in exchange for an interest in a Global Note pursuant to
Section 312(c) shall, unless such exchange is made on or after the Resale Restriction Termination Date applicable to such Note and except as otherwise provided in Section 203 and Section 313, bear the Private
Placement Legend. 
 (h) Notwithstanding the foregoing, through the Restricted Period, a beneficial interest in a Regulation S Global Note
may be held only through designated Agent Members holding on behalf of Euroclear or Clearstream unless delivery is made in accordance with the applicable provisions of Section 313. 

Section 313. Special Transfer Provisions. 

(1) Transfers to Non-U.S. Persons. The following provisions shall apply with respect to the registration of any proposed
transfer of a Note that is a Restricted Security to any Non-U.S. Person: The Note Registrar shall register such transfer if it complies with all other applicable requirements of this Indenture (including Section 305) and, 

(a) if (x) such transfer is after the relevant Resale Restriction Termination Date with respect to such Note or
(y) the proposed transferor has delivered to the Note Registrar and the Company and the Trustee a Regulation S Certificate and, unless otherwise agreed by the Company, an opinion of counsel, certifications and other information
satisfactory to the Company, and 
 (b) if the proposed transferor is or is acting through an Agent Member holding a
beneficial interest in a Global Note, upon receipt by the Note Registrar and the Company and the Trustee of (x) the certificate, opinion, certifications and other information, if any, required by clause (a) above and
(y) written instructions given in accordance with the procedures of the Note Registrar and of the Depositary; 
 whereupon (i) the
Note Registrar shall reflect on its books and records the date and (if the transfer does not involve a transfer of any Outstanding Physical Note) a decrease in the principal amount of the relevant Global Note in an amount equal to the principal
amount of the beneficial interest in the relevant Global Note to be transferred, and (ii) either (A) if the proposed transferee 

  
 72 








 
is or is acting through an Agent Member holding a beneficial interest in a relevant Regulation S Global Note, the Note Registrar shall reflect on its books and records the date and an increase in
the principal amount of such Regulation S Global Note in an amount equal to the principal amount of the beneficial interest being so transferred or (B) otherwise the Company shall execute and (upon receipt of an Authentication Order) the
Trustee shall authenticate and deliver one or more Physical Notes of like tenor and amount. 
 (2) Transfers to QIBs.
The following provisions shall apply with respect to the registration of any proposed transfer of a Note that is a Restricted Security to a QIB (excluding transfers to Non-U.S. Persons): The Note Registrar shall register such transfer if it complies
with all other applicable requirements of this Indenture (including Section 305) and, 
 (a) if such transfer is
being made by a proposed transferor who has checked the box provided for on the form of such Note stating, or has otherwise certified to the Note Registrar and the Company and the Trustee in writing, that the sale has been made in compliance with
the provisions of Rule 144A to a transferee who has signed the certification provided for on the form of such Note stating, or has otherwise certified to Note Registrar and the Company and the Trustee in writing, that it is purchasing such Note for
its own account or an account with respect to which it exercises sole investment discretion and that it and any such account is a QIB within the meaning of Rule 144A, and is aware that the sale to it is being made in reliance on Rule 144A and
acknowledges that it has received such information regarding the Company as it has requested pursuant to Rule 144A or has determined not to request such information and that it is aware that the transferor is relying upon its foregoing
representations in order to claim the exemption from registration provided by Rule 144A; and 
 (b) if the proposed
transferee is an Agent Member, and the Note to be transferred consists of a Physical Note that after transfer is to be evidenced by an interest in a Global Note or consists of a beneficial interest in a Global Note that after the transfer is to be
evidenced by an interest in a different Global Note, upon receipt by the Note Registrar of written instructions given in accordance with the Depositary’s and the Note Registrar’s procedures, whereupon the Note Registrar shall reflect on
its books and records the date and an increase in the principal amount of the transferee Global Note in an amount equal to the principal amount of the Physical Note or such beneficial interest in such transferor Global Note to be transferred, and
the Trustee shall cancel the Physical Note so transferred or reflect on its books and records the date and a decrease in the principal amount of such transferor Global Note, as the case may be. 

(3) Limitation on Issuance of Physical Notes. No Physical Note shall be exchanged for a beneficial interest in any
Global Note, except in accordance with Section 312 and this Section 313. 
 A beneficial owner of an interest in a
Temporary Regulation S Global Note (and, in the case of any Additional Notes for which no Temporary Regulation S Global Note is issued, 

  
 73 








 
any Regulation S Global Note) shall not be permitted to exchange such interest for a Physical Note or (in the case of such interest in a Temporary Regulation S Global Note) an interest in a
Permanent Regulation S Global Note until a date, which must be after the end of the Restricted Period, on which the Company receives a certificate of beneficial ownership substantially in the form attached hereto as Exhibit C from such
beneficial owner (a “Certificate of Beneficial Ownership”). Such date, as it relates to a Regulation S Global Note, is herein referred to as the “Regulation S Note Exchange Date.” 

(4) Private Placement Legend. Upon the transfer, exchange or replacement of Notes not bearing the Private Placement
Legend, the Note Registrar shall deliver Notes that do not bear the Private Placement Legend. Upon the transfer, exchange or replacement of Notes bearing the Private Placement Legend, the Note Registrar shall deliver only Notes that bear the Private
Placement Legend unless (i) the requested transfer is after the relevant Resale Restriction Termination Date with respect to such Notes, (ii) upon written request of the Company after there is delivered to the Note Registrar
an opinion of counsel (which opinion and counsel are satisfactory to the Company) to the effect that neither such legend nor the related restrictions on transfer are required in order to maintain compliance with the provisions of the Securities Act,
(iii) with respect to a Regulation S Global Note (on or after the Regulation S Note Exchange Date with respect to such Regulation S Global Note) or Regulation S Physical Note, in each case with the agreement of the Company, or
(iv) such Notes are sold or exchanged pursuant to an effective registration statement under the Securities Act. 

(5) Other Transfers. The Note Registrar shall effect and register, upon receipt of a written request from the Company to
do so, a transfer not otherwise permitted by this Section 313, such registration to be done in accordance with the otherwise applicable provisions of this Section 313, upon the furnishing by the proposed transferor or
transferee of a written opinion of counsel (which opinion and counsel are satisfactory to the Company) to the effect that, and such other certifications or information as the Company may require (including, in the case of a transfer to an Accredited
Investor (as defined in Rule 501(a)(1), (2), (3) or (7) under Regulation D promulgated under the Securities Act), a certificate substantially in the form attached hereto as Exhibit F) to confirm that, the proposed transfer is
being made pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act. 
 A Note
that is a Restricted Security may not be transferred other than as provided in this Section 313. A beneficial interest in a Global Note that is a Restricted Security may not be exchanged for a beneficial interest in another Global Note
other than through a transfer in compliance with this Section 313. 
 (6) General. By its acceptance of
any Note bearing the Private Placement Legend, each Holder of such a Note acknowledges the restrictions on transfer of such Note set forth in this Indenture and in the Private Placement Legend and agrees that it will transfer such Note only as
provided in this Indenture. 

  
 74 








 The Note Registrar shall retain copies of all letters, notices and other written communications
received pursuant to Section 312 or this Section 313 (including all Notes received for transfer pursuant to this Section 313). The Company shall have the right to require the Note Registrar to deliver to the
Company, at the Company’s expense, copies of all such letters, notices or other written communications at any reasonable time upon the giving of reasonable written notice to the Note Registrar. 

In connection with any transfer of any Note, the Trustee, the Note Registrar and the Company shall be entitled to receive, shall be under no
duty to inquire into, may conclusively presume the correctness of, and shall be fully protected in relying upon the certificates, opinions and other information referred to herein (or in the forms provided herein, attached hereto or to the Notes, or
otherwise) received from any Holder and any transferee of any Note regarding the validity, legality and due authorization of any such transfer, the eligibility of the transferee to receive such Note and any other facts and circumstances related to
such transfer. 
 Section 314. Payment of Additional Interest. (a) Under certain circumstances, the Company will be
obligated to pay certain additional amounts of interest to the Holders of certain Initial Notes, as more particularly set forth in such Initial Notes. 

(b) Under certain circumstances the Company may be obligated to pay certain additional amounts of interest to the Holders of certain Initial
Additional Notes, as may be more particularly set forth in such Initial Additional Notes. 
 (c) Prior to any Interest Payment Date on which
any such additional interest is payable, the Company shall give notice to the Trustee of the amount of any such additional interest due on such Interest Payment Date. The Trustee shall have no obligation to independently determine whether additional
interest is payable or to confirm the amount of additional interest that is in fact payable. 
 ARTICLE IV 

COVENANTS 

Section 401. Payment of Principal, Premium and Interest. The Company shall duly and punctually pay the principal of (and premium,
if any) and interest on the Notes in accordance with the terms of the Notes and this Indenture. Principal amount (and premium, if any) and interest on the Notes shall be considered paid on the date due if the Company shall have deposited with the
Paying Agent (if other than the Company or a wholly-owned Domestic Subsidiary of the Company) as of 12:00 p.m. New York City time on the due date money in immediately available funds and designated for and sufficient to pay all principal amount (and
premium, if any) and interest then due. At the option of the Company, payment of Interest on a Note may be made through the Paying Agent by wire transfer of immediately available funds to the account designated to the Company by the Person entitled
thereto or by check mailed to the address of the Person entitled thereto as such address shall appear in the Note Register. 

  
 75 








 Section 402. Maintenance of Office or Agency. (a) The Company shall maintain in
the United States an office or agency where Notes may be presented or surrendered for payment, where Notes may be surrendered for 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 shall give prompt written notice to the Trustee of the location, and of any change in the location, of such office or agency. If at any time the Company shall fail to maintain such 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; provided that no service of legal process may be made against the Company at any
office of the Trustee. 
 (b) The Company may also from time to time designate one or more other offices or agencies where the Notes may be
presented or surrendered for any or all purposes and may from time to time rescind such designations. 
 The Company hereby designates the
Corporate Trust Office of the Trustee as one such office or agency of the Company in accordance with Section 305. 

Section 403. Money for Payments to Be Held in Trust. If the Company shall at any time act as Paying Agent, it shall, on or before
12:00 p.m., New York City time, on 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 shall promptly notify the Trustee in writing of its action or failure so to act. 

If the Company is not acting as Paying Agent, it shall, on or prior to 12:00 p.m., New York City time, on each due date of the principal of
(and premium, if any) or interest on, any Notes, deposit with a 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 shall promptly notify the Trustee in writing of its action or failure so to act. 

If the Company is not acting as Paying Agent, the Company shall cause any Paying Agent other than the Trustee to execute and deliver to the
Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section 403, that such Paying Agent shall 

(1) hold all sums held by it for the payment of principal of (and premium, if any) or interest on Notes of such series in trust
for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as herein provided; 

  
 76 








 (2) give the Trustee notice of any default by the Company (or any other obligor
upon the Notes) in the making of any such payment of principal (and premium, if any) or interest; 
 (3) at any time during
the continuance of any such default, upon the written request of the Trustee, forthwith pay to the Trustee all sums so held in trust by such Paying Agent; and 

(4) acknowledge, accept and agree to comply in all respects with the provisions of this Indenture relating to the duties,
rights and liabilities of such Paying Agent. 
 The Company may at any time, for the purpose of obtaining the satisfaction and discharge of
such Notes, this Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such 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 such Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such money. 

Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of principal of (and premium,
if any) or interest on any Note and remaining unclaimed for two years after such principal (and premium, if any) or interest has become due and payable shall be paid to the Company on Company Request, 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 unless an applicable abandoned property law designates another Person, and all liability of the
Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease. 

Section 404. [Reserved].

applicable, such audited or reviewed financial statements or information no later than the first anniversary of the date on which the same was otherwise required pursuant to the preceding provisions of this paragraph (such initial date, the
“Reporting Date”) and (ii) if the Company (or, any Parent whose financial statements satisfy the Company’s reporting obligations under this Section 405) makes such an election and such filing has not been made,
or such information, documents and reports have not been transmitted or made available, as the case may be, within 90 days after such Reporting Date, liquidated damages will accrue on the Notes at a rate of 0.50% per annum from the date that is
90 days after such Reporting Date to the earlier of (x) the date on which such filing has been made, or such information, documents and reports have been transmitted or made available, as the case may be, and (y) the first
anniversary of such Reporting Date (provided that not more than 0.50% per annum in liquidated damages shall be payable for any period regardless of the number of such elections by the Company). The Trustee shall have no independent
responsibility to determine if liquidated damages are due or the amount of any such liquidated damages. 
 The Company will be deemed to
have satisfied the requirements of this Section 405 if any Parent, in the case of paragraph (a), furnishes or makes available information regarding Parent of the type otherwise so required with respect to the Company under such paragraph
(a) (provided, that in the case of the financial statements required to be delivered pursuant to clauses (i) and (ii) of paragraph (a), the financial statements of Parent shall include a footnote depicting condensed

Officer’s Certificate). Subject to Article VII, the Trustee is not obligated to confirm that the Company has complied with its obligations contained in this Section 405 to file such reports with the SEC or post such

Indebtedness is not recourse to the Company or any Restricted Subsidiary that is not a Special Purpose Subsidiary (other than with respect to Special Purpose Financing Undertakings); (2) in the event such Indebtedness shall become
recourse to the Company or any Restricted Subsidiary that is not a Special Purpose Subsidiary (other than with respect to Special Purpose Financing Undertakings), such Indebtedness will be deemed to be, and must be classified by the Company as,
Incurred at such time (or at the time initially Incurred) under one or more of the other provisions of this Section 407 for so long as such Indebtedness shall be so recourse; and (3) in the event that at any time thereafter

arising under any Guarantee, Lien or letter of credit, bankers’ acceptance or other similar instrument or obligation supporting such Indebtedness shall be disregarded to the extent that such Guarantee, Lien or letter of credit, bankers’

determined after giving effect to the application of proceeds of any such Indebtedness to refinance any such other Indebtedness; (vi) if any Indebtedness is Incurred 

  
 84 








 
to refinance Indebtedness initially Incurred (or, Indebtedness Incurred to refinance Indebtedness initially Incurred) in reliance on a basket measured by reference to a percentage of Four Quarter
Consolidated EBITDA at the time of Incurrence, and such refinancing would cause the percentage of Four Quarter Consolidated EBITDA restriction to be exceeded if calculated based on the Four Quarter Consolidated EBITDA on the date of such
refinancing, such percentage of Four Quarter Consolidated EBITDA restriction shall not be deemed to be exceeded (and such refinancing Indebtedness shall be deemed permitted) so long as the principal amount of such refinancing Indebtedness does not
exceed the principal amount of such Indebtedness being refinanced, plus the aggregate amount of fees, underwriting discounts, premiums and other costs and expenses (including accrued and unpaid interest) Incurred or payable in connection with such
refinancing; and (vii) if any Indebtedness is Incurred to refinance Indebtedness initially Incurred (or, Indebtedness Incurred to refinance Indebtedness initially Incurred) in reliance on any provision of Section 407(b)
measured by a dollar amount, such dollar amount shall not be deemed to be exceeded (and such refinancing Indebtedness shall be deemed permitted) to the extent the principal amount of such newly Incurred Indebtedness does not exceed the principal
amount of such Indebtedness being refinanced, plus the aggregate amount of fees, underwriting discounts, premiums and other costs and expenses (including accrued and unpaid interest) Incurred or payable in connection with such refinancing. 

Notwithstanding anything herein to the contrary, Indebtedness Outstanding on the Issue Date under the Senior Credit Facilities shall be classified as Incurred
under Section 407(b), and not under Section 407(a). 
 (d) For purposes of determining compliance with any
dollar denominated restriction on the Incurrence of Indebtedness denominated in a foreign currency, the dollar equivalent principal amount of such Indebtedness Incurred pursuant thereto shall be calculated based on the relevant currency exchange
rate in effect on the date that such Indebtedness was Incurred, in the case of term Indebtedness, or first committed, in the case of revolving or deferred draw Indebtedness, provided that (x) the dollar equivalent principal amount
of any such Indebtedness outstanding on the Issue Date shall be calculated based on the relevant currency exchange rate in effect on the Issue Date, (y) if such Indebtedness is Incurred to refinance other Indebtedness denominated in a
foreign currency (or in a different currency from such Indebtedness so being Incurred), and such refinancing would cause the applicable dollar denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on
the date of such refinancing, such dollar denominated restriction shall be deemed not to have been exceeded so long as the principal amount of such refinancing Indebtedness does not exceed (i) the outstanding or committed principal
amount (whichever is higher) of such Indebtedness being refinanced plus (ii) the aggregate amount of fees, underwriting discounts, premiums and other costs and expenses (including accrued and unpaid interest) Incurred or payable
in connection with such refinancing and (z) the dollar equivalent principal amount of Indebtedness denominated in a foreign currency and Incurred pursuant to the Senior Credit Facilities shall be calculated based on the relevant currency
exchange rate in effect on, at the Company’s option, (A) the Issue Date, (B) any date on which any of the respective commitments under the applicable Senior Credit Facilities shall be reallocated between or among
facilities or  

  
 85 








 
subfacilities thereunder, or on which such rate is otherwise calculated for any purpose thereunder, or (C) the date of such Incurrence. The principal amount of any Indebtedness
Incurred to refinance other Indebtedness, if Incurred in a different currency from the Indebtedness being refinanced, shall be calculated based on the currency exchange rate applicable to the currencies in which such respective Indebtedness is
denominated that is in effect on the date of such refinancing. 
 Section 408. [Reserved]. 

Section 409. Limitation on Restricted Payments. (a) The Company shall not, and shall not permit any Restricted Subsidiary,

(x) dividends or distributions payable solely in its Capital Stock (other than Disqualified Stock) and (y) dividends or distributions payable to the Company or any Restricted Subsidiary (and, in the case of any such
Restricted Subsidiary making such dividend or distribution, to other holders of its Capital Stock on no more than a pro rata basis, measured by value), (ii) purchase, redeem, retire or otherwise acquire for value any Capital Stock

purchase, repurchase, redemption, defeasance or other acquisition or retirement) or (iv) make any Investment (other than a Permitted Investment) in any Person (any such dividend, distribution, purchase, repurchase, redemption,
defeasance, other acquisition or retirement or Investment being herein referred to as a “Restricted Payment”), if at the time the Company or such Restricted Subsidiary makes such Restricted Payment after giving effect thereto: 

(1) a Default shall have occurred and be continuing (or would result therefrom); 

(2) the Company could not Incur at least an additional $1.00 of Indebtedness pursuant to Section 407(a); or 

  
 86 








 (3) the aggregate amount of such Restricted Payment and all other Restricted
Payments (the amount so expended, if other than in cash, to be as determined in good faith by the Board of Directors, whose determination shall be conclusive and evidenced by a resolution of the Board of Directors) declared or made subsequent to the
Issue Date and then outstanding would exceed, without duplication, the sum of: 
 (A) (i) $275.0 million plus
(ii) 50.0% of the Consolidated Net Income accrued during the period (treated as one accounting period) beginning on October 1, 2016 to the end of the most recent fiscal quarter ending prior to the date of such Restricted Payment for
which consolidated financial statements of the Company (or, any Parent whose financial statements satisfy the Company’s reporting obligations under Section 405) are available (or, in case such Consolidated Net Income shall be a
negative number, 100.0% of such negative number); 
 (B) the aggregate Net Cash Proceeds and the fair value (as determined in
good faith by the Company) of property or assets received (x) by the Company as capital contributions to the Company after the Issue Date or from the issuance or sale (other than to a Restricted Subsidiary) of its Capital Stock (other

Subsidiary to (i) pay dividends or make any other distributions on its Capital Stock or pay any Indebtedness or other obligations owed to the Company, (ii) make any loans or advances to the Company or
(iii) transfer any of its property or assets to the Company (provided that dividend or liquidation priority between classes of Capital Stock, or subordination of any obligation (including the application of any remedy bars
thereto) to any other obligation, will not be deemed to constitute such an encumbrance or restriction), except any encumbrance or restriction: 

(1) pursuant to an agreement or instrument in effect at or entered into on the Issue Date, any Credit Facility, this Indenture
or the Notes; 
 (2) pursuant to any agreement or instrument of a Person, or relating to Indebtedness or Capital Stock of a
Person, which Person is acquired by or merged or consolidated with or into the Company or any Restricted Subsidiary, or which agreement or instrument is assumed by the Company or any Restricted Subsidiary in connection


  
 90 








 
with an acquisition of assets from such Person, or any other transaction entered into in connection with any such acquisition, merger or consolidation, as in effect at the time of such
acquisition, merger, consolidation or transaction (except to the extent that such Indebtedness was incurred to finance, or otherwise in connection with, such acquisition, merger, consolidation or transaction); provided that for purposes of
this clause (2), if a Person other than the Company is the Successor Company with respect thereto, any Subsidiary thereof or agreement or instrument of such Person or any such Subsidiary shall be deemed acquired or assumed, as the case may be, by
the Company or a Restricted Subsidiary, as the case may be, when such Person becomes such Successor Company; 
 (3) pursuant
to an agreement or instrument (a “Refinancing Agreement”) effecting a refinancing of Indebtedness Incurred or outstanding pursuant or relating to, or that otherwise extends, renews, refunds, refinances or replaces, any agreement or
instrument referred to in clause (1) or (2) of this Section 410 or this clause (3) (an “Initial Agreement”) or that is, or is contained in, any amendment, supplement or other modification to an Initial
Agreement or Refinancing Agreement (an “Amendment”); provided, however, that the encumbrances and restrictions contained in any such Refinancing Agreement or Amendment taken as a whole are not materially less favorable
to the Holders of the Notes than encumbrances and restrictions contained in the Initial Agreement or Initial Agreements to which such Refinancing Agreement or Amendment relates (as determined in good faith by the Company); 

(4) (A) pursuant to any agreement or instrument that restricts in a customary manner the assignment or transfer thereof,
or the subletting, assignment or transfer of any property or asset subject thereto, (B) by virtue of any transfer of, agreement to transfer, option or right with respect to, or Lien on, any property or assets of the Company or any

Subsidiary, (E) pursuant to Purchase Money Obligations that impose encumbrances or restrictions on the property or assets so acquired, (F) on cash or other deposits, net worth or inventory imposed by customers or suppliers
under agreements entered into in the ordinary course of business, (G) pursuant to customary provisions contained in agreements and instruments entered into in the ordinary course of business (including but not limited to leases and
licenses) or in joint venture and other similar agreements or in shareholder, partnership, limited liability company and other similar agreements in respect of non-wholly owned Restricted Subsidiaries, (H) that arises or is agreed to in
the ordinary course of business and does not detract from the value of property or assets of the Company or any Restricted Subsidiary in any manner material to the Company or such Restricted Subsidiary, (I) pursuant to Hedging Obligations or
Bank Products Obligations or (J) pursuant to Related Corporation Contracts; 

  
 91 








 (5) with respect to any agreement for the direct or indirect disposition of
Capital Stock of any Person, property or assets, imposing restrictions with respect to such Person, Capital Stock, property or assets pending the closing of such sale or disposition; 

(6) by reason of any applicable law, rule, regulation or order, or required by any regulatory authority having jurisdiction
over the Company or any Restricted Subsidiary or any of their businesses, including any such law, rule, regulation, order or requirement applicable in connection with such Restricted Subsidiary’s status (or the status of any Subsidiary of such
Restricted Subsidiary) as a Captive Insurance Subsidiary; or 
 (7) pursuant to an agreement or instrument
(A) relating to any Indebtedness permitted to be Incurred subsequent to the Issue Date pursuant to Section 407 (i) if the encumbrances and restrictions contained in any such agreement or instrument taken as a
whole are not materially less favorable to the Holders of the Notes than the encumbrances and restrictions contained in the Initial Agreements (as determined in good faith by the Company) or (ii) if such encumbrance or restriction is not
materially more disadvantageous to the Holders of the Notes than is customary in comparable financings (as determined in good faith by the Company) and either (x) the Company determines in good faith that such encumbrance or restriction
will not materially affect the Company’s ability to make principal or interest payments on the Notes or (y) such encumbrance or restriction applies only if a default occurs in respect of a payment or financial covenant relating to
such Indebtedness, (B) relating to any sale of receivables by or Indebtedness of a Foreign Subsidiary or (C) relating to Indebtedness of or a Financing Disposition by or to or in favor of any Special Purpose Entity. 

Section 411. Limitation on Sales of Assets and Subsidiary Stock. (a) The Company will not, and will not permit any Restricted
Subsidiary to, make any Asset Disposition unless: 
 (i) the Company or such Restricted Subsidiary receives consideration
(including by way of relief from, or by any other Person assuming responsibility for, any liabilities, contingent or otherwise) at the time of such Asset Disposition at least equal to the fair market value of the shares and assets subject to such
Asset Disposition, as such fair market value (on the date a legally binding commitment for such Asset Disposition was entered into) may be determined (and shall be determined, to the extent such Asset Disposition or any series of related Asset
Dispositions involves aggregate consideration in excess of $100.0 million) in good faith by the Company, whose determination shall be conclusive (including as to the value of all noncash consideration); 

  
 92 








 (ii) in the case of any Asset Disposition (or series of related Asset
Dispositions) having a Fair Market Value (on the date a legally binding commitment for such Asset Disposition was entered into) of $100.0 million or more, at least 75.0% of the consideration therefor (excluding, in the case of an Asset
Disposition (or series of related Asset Dispositions), any consideration by way of relief from, or by any other Person assuming responsibility for, any liabilities, contingent or otherwise, that are not Indebtedness) received by the Company or such
Restricted Subsidiary is in the form of cash; and 
 (iii) an amount equal to 100.0% (as may be adjusted pursuant to clause
(3) of the last proviso to this Section 411(a)(iii)) of the Net Available Cash from such Asset Disposition is applied by the Company (or any Restricted Subsidiary, as the case may be) as follows: 

(A) first, either (x) to the extent the Company or such Restricted Subsidiary elects (or is required by the
terms of any Credit Facility Indebtedness, any Senior Indebtedness of the Company or any Subsidiary Guarantor or any Indebtedness of a Restricted Subsidiary that is not a Subsidiary Guarantor), to prepay, repay or purchase any such Indebtedness or
(in the case of letters of credit, bankers’ acceptances or other similar instruments) cash collateralize any such Indebtedness (in each case other than Indebtedness owed to the Company or a Restricted Subsidiary) within 450 days after the later
of the date of such Asset Disposition and the date of receipt of such Net Available Cash, or (y) to the extent the Company or such Restricted Subsidiary elects, to invest in Additional Assets (including by means of an investment in
Additional Assets by a Restricted Subsidiary with an amount equal to Net Available Cash received by the Company or another Restricted Subsidiary) within 450 days from the later of the date of such Asset Disposition and the date of receipt of such
Net Available Cash, or, if such investment in Additional Assets is a project authorized by the Board of Directors that will take longer than such 450 days to complete, the period of time necessary to complete such project; 

(B) second, to the extent of the balance of such Net Available Cash after application in accordance with clause
(A) above (such balance, the “Excess Proceeds”), to make an offer to purchase the Notes and (to the extent the Company or such Restricted Subsidiary elects, or is required by the terms thereof) to make an offer to purchase,
redeem or repay and/or to purchase, redeem or repay any other Senior Indebtedness of the Company or a Restricted Subsidiary, pursuant and subject to Section 411(b) and Section 411(c) and the agreements governing such other
Indebtedness; provided the offer to purchase the Notes shall be on no less than a pro rata basis with such other Senior Indebtedness; and 

(C) third, to the extent of the balance of such Net Available Cash after application in accordance with clauses (A)
and (B) above (the aggregate of any 

  
 93 








 
such amounts, “Declined Excess Proceeds”), to fund (to the extent consistent with any other applicable provision of this Indenture) any general corporate purpose (including but
not limited to the repurchase, repayment or other acquisition or retirement of any Subordinated Obligations and the making of other Restricted Payments); 

provided, however, that (1) in connection with any prepayment, repayment or purchase of Indebtedness pursuant to
clause (A)(x) or (B) above, the Company or such Restricted Subsidiary will retire such Indebtedness and will cause the related loan commitment (if any) to be permanently reduced in an amount equal to the principal amount so prepaid, repaid
or purchased; (2) the Company (or any Restricted Subsidiary, as the case may be) may elect to invest in Additional Assets prior to receiving the Net Available Cash attributable to any given Asset Disposition (provided that such
investment shall be made no earlier than the earliest of notice to the Trustee of the relevant Asset Disposition, execution of a definitive agreement for the relevant Asset Disposition, and consummation of the relevant Asset Disposition) and deem
the amount so invested to be applied pursuant to and in accordance with clause (A)(y) above with respect to such Asset Disposition; and (3) the foregoing percentage in this Section 411(a)(iii) shall be reduced to 50% if the
Consolidated Total Leverage Ratio would be equal to or less than 3.50:1.00 after giving pro forma effect to any application of such Net Available Cash as set forth herein (any Net Available Cash in respect of Asset Dispositions not required to be
applied in accordance with this clause (iii) as a result of the application of this proviso shall collectively constitute “Total Leverage Excess Proceeds”). 

Notwithstanding the foregoing provisions of this Section 411, the Company and the Restricted Subsidiaries shall not be required to
apply any Net Available Cash or equivalent amount in accordance with this Section 411 except to the extent that the aggregate Net Available Cash from all Asset Dispositions or equivalent amount that is not applied in accordance with this
Section 411 (excluding all Total Leverage Excess Proceeds) exceeds $100.0 million. If the aggregate principal amount of Notes and/or other Indebtedness of the Company or a Restricted Subsidiary validly tendered and not withdrawn (or
otherwise subject to purchase, redemption or repayment) in connection with an offer pursuant to clause (B) above exceeds the Excess Proceeds, the Excess Proceeds will be apportioned between such Notes and such other Indebtedness of the Company
or a Restricted Subsidiary, with the portion of the Excess Proceeds payable in respect of such Notes to equal the lesser of (x) the Excess Proceeds amount multiplied by a fraction, the numerator of which is the outstanding principal
amount of such Notes and the denominator of which is the sum of the outstanding principal amount of the Notes and the outstanding principal amount of the relevant other Indebtedness of the Company or a Restricted Subsidiary, and (y) the
aggregate principal amount of Notes validly tendered and not withdrawn. 
 For the purposes of Section 411(a)(ii), the following
are deemed to be cash: (1) Temporary Cash Investments and Cash Equivalents; (2) the assumption of Indebtedness of the Company (other than Disqualified Stock of the Company) or any Restricted Subsidiary and the release of the
Company or such Restricted Subsidiary from all liability on payment of the principal amount of such Indebtedness in connection with such Asset Disposition; 

  
 94 








 
(3) Indebtedness of any Restricted Subsidiary that is no longer a Restricted Subsidiary as a result of such Asset Disposition, to the extent that the Company and each other Restricted
Subsidiary are released from any Guarantee of payment of the principal amount of such Indebtedness in connection with such Asset Disposition; (4) securities received by the Company or any Restricted Subsidiary from the transferee that
are converted by the Company or such Restricted Subsidiary into cash within 180 days; (5) consideration consisting of Indebtedness of the Company or any Restricted Subsidiary; (6) Additional Assets; and (7) any
Designated Noncash Consideration received by the Company or any of its Restricted Subsidiaries in an Asset Disposition having an aggregate Fair Market Value, taken together with all other Designated Noncash Consideration received pursuant to this
clause, not to exceed an aggregate amount at any time outstanding equal to the greater of $425.0 million and 33.0% of Four Quarter Consolidated EBITDA (with the Fair Market Value of each item of Designated Noncash Consideration being measured on the
date a legally binding commitment for such disposition (or, if later, for the payment of such item) was entered into and without giving effect to subsequent changes in value). 

(b) In the event of an Asset Disposition that requires the purchase of Notes pursuant to Section 411(a)(iii)(B), the Company will
be required to purchase Notes tendered pursuant to an offer by the Company for the Notes (the “Offer”) at a purchase price of 100.0% of their principal amount plus accrued and unpaid interest to the date of purchase in accordance
with the procedures (including prorating in the event of oversubscription) set forth in Section 411(c). If the aggregate purchase price of the Notes tendered pursuant to the Offer is less than the Net Available Cash allotted to the
purchase of Notes, the remaining Net Available Cash will be available to the Company and the Restricted Subsidiaries for use in accordance with Section 411(a)(iii)(B) (to repay other Indebtedness of the Company or a Restricted
Subsidiary) or Section 411(a)(iii)(C). The Company shall not be required to make an Offer for Notes pursuant to this Section 411 if the Net Available Cash available therefor (after application of the proceeds as provided in
Section 411(a)(iii)(A)) is less than $100.0 million for any particular Asset Disposition (which lesser amounts shall be carried forward for purposes of determining whether an Offer is required with respect to the Net Available Cash from
any subsequent Asset Disposition). No Note will be repurchased in part if less than the Minimum Denomination in original principal amount of such Note would be left outstanding. 

(c) The Company shall, not later than 45 days after the Company becomes obligated to make an Offer pursuant to this Section 411,
send a notice to each Holder with a copy to the Trustee stating: (1) that an Asset Disposition that requires the purchase of a portion of the Notes has occurred and that such Holder has the right (subject to the prorating described
below) to require the Company to purchase a portion of such Holder’s Notes at a purchase price in cash equal to 100.0% of the principal amount thereof, plus accrued and unpaid interest, if any, to the date of purchase (subject to the
right of Holders of record on a record date to receive interest on the relevant Interest Payment Date falling prior to or on the purchase date); (2) the repurchase date (which shall be no earlier than 10 days nor later than 60 days from
the date such notice is sent); (3) the instructions determined by the Company, consistent with this Section 411, that a Holder must follow in order to have its Notes purchased; and (4) the amount of the Offer. If,


  
 95 








 
upon the expiration of the period for which the Offer remains open, the aggregate principal amount of Notes surrendered by Holders exceeds the amount of the Offer, the Company shall select the
Notes to be purchased on a pro rata basis (with such adjustments as may be deemed appropriate by the Company so that only Notes in the Minimum Denomination or integral multiples of $1,000 in excess thereof shall be purchased). 

(d) The Company will comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other
securities laws or regulations in connection with the repurchase of Notes pursuant to this Section 411. To the extent that the provisions of any securities laws or regulations conflict with provisions of this Section 411, the
Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 411 by virtue thereof. 

Section 412. Limitation on Transactions with Affiliates. (a) The Company will not, and will not permit any Restricted
Subsidiary to, directly or indirectly, enter into or conduct any transaction or series of related transactions (including the purchase, sale, lease or exchange of any property or the rendering of any service) with any Affiliate of the Company (an
“Affiliate Transaction”) involving aggregate consideration in excess of $50.0 million unless (i) the terms of such Affiliate Transaction are not materially less favorable to the Company or such Restricted Subsidiary, as
the case may be, than those that could be obtained at the time in a transaction with a Person who is not such an Affiliate and (ii) if such Affiliate Transaction involves aggregate consideration in excess of $100.0 million, the terms of
such Affiliate Transaction have been approved by a majority of the Board of Directors. For purposes of this Section 412(a), any Affiliate Transaction shall be deemed to have satisfied the requirements set forth in this
Section 412(a) if (x) such Affiliate Transaction is approved by a majority of the Disinterested Directors or (y) in the event there are no Disinterested Directors, a fairness opinion is provided by a nationally
recognized appraisal or investment banking firm with respect to such Affiliate Transaction. 
 (b) The provisions of
Section 412(a) will not apply to: 
 (i) any Restricted Payment Transaction, 

(ii) (1) the entering into, maintaining or performance of any employment or consulting contract, collective bargaining
agreement, benefit plan, program or arrangement, related trust agreement or any other similar arrangement for or with any current or former management member, employee, officer or director or consultant of or to the Company, any Restricted
Subsidiary or any Parent heretofore or hereafter entered into in the ordinary course of business, including vacation, health, insurance, deferred compensation, severance, retirement, savings or other similar plans, programs or arrangements,
(2) payments, compensation, performance of indemnification or contribution obligations, the making or cancellation of loans in the ordinary course of business to any such management members, employees, officers, directors or consultants,
(3) any issuance, grant or award of stock, options, other equity related interests or other 

  
 96 








 
securities, to any such management members, employees, officers, directors or consultants, (4) the payment of reasonable fees to directors of the Company or any of its Subsidiaries or
any Parent (as determined in good faith by the Company, such Subsidiary or such Parent), or (5) Management Advances and payments in respect thereof (or in reimbursement of any expenses referred to in the definition of such term), 

(iii) any transaction between or among any of the Company, one or more Restricted Subsidiaries, or one or more Special Purpose
Entities, 
 (iv) any transaction arising out of agreements or instruments in existence on the Issue Date, and any payments
made pursuant thereto, 
 (v) any transaction in the ordinary course of business on terms that are fair to the Company and
its Restricted Subsidiaries in the reasonable determination of the Board of Directors or senior management of the Company, or are not materially less favorable to the Company or the relevant Restricted Subsidiary than those that could be obtained at
the time in a transaction with a Person who is not an Affiliate of the Company, 
 (vi) any transaction in the ordinary
course of business, or approved by a majority of the Board of Directors, between the Company or any Restricted Subsidiary and any Affiliate of the Company controlled by the Company that is a joint venture or similar entity, 

(vii) [reserved], 

(viii) the Transactions, all transactions in connection therewith (including but not limited to the financing thereof), and all
fees and expenses paid or payable in connection with the Transactions, 
 (ix) any issuance or sale of Capital Stock (other
than Disqualified Stock) of the Company or any capital contribution to the Company, 
 (x) [reserved], and 

(xi) any transaction between or among the Company or any Restricted Subsidiary and any Related Corporation pursuant to or in
connection with a Related Corporation Contract. 
 Section 413. Limitation on Liens. The Company shall not, and shall not permit
any Restricted Subsidiary to, directly or indirectly, create or permit to exist any Lien (other than Permitted Liens) on any of its property or assets (including Capital Stock of any other Person), whether owned on the date of this Indenture or
thereafter acquired, securing any Indebtedness (the “Initial Lien”), unless contemporaneously therewith effective provision is made to secure the Indebtedness due under this Indenture and the Notes or, in respect of Liens on


  
 97 








 
any Restricted Subsidiary’s property or assets, any Subsidiary Guarantee of such Restricted Subsidiary, equally and ratably with (or on a senior basis to, in the case of Subordinated
Obligations or Guarantor Subordinated Obligations) such obligation for so long as such obligation is so secured by such Initial Lien. Any such Lien thereby created in favor of the Notes or any such Subsidiary Guarantee will be automatically and
unconditionally released and discharged upon (i) the release and discharge of the Initial Lien to which it relates, (ii) in the case of any such Lien in favor of any such Subsidiary Guarantee, upon the termination and
discharge of such Subsidiary Guarantee in accordance with the terms of Section 1303 or (iii) any sale, exchange or transfer (other than a transfer constituting a transfer of all or substantially all of the assets of the
Company that is governed by Section 501) to any Person not an Affiliate of the Company of the property or assets secured by such Initial Lien, or of all of the Capital Stock held by the Company or any Restricted Subsidiary in, or all or
substantially all the assets of, any Restricted Subsidiary creating such Initial Lien. 
 Section 414. Future Subsidiary
Guarantors. The Company will cause each Domestic Subsidiary that guarantees payment by the Company or any Subsidiary Guarantor of any Indebtedness of the Company or any such Subsidiary Guarantor under either of the Senior Credit Facilities or
any Capital Market Indebtedness (including by reason of being a borrower under the Senior ABL Facility on a joint and several basis with the Company) to execute and deliver to the Trustee within 30 days a supplemental indenture or other instrument
pursuant to which such Domestic Subsidiary will guarantee payment of the Notes, whereupon such Domestic Subsidiary will become a Subsidiary Guarantor for all purposes under this Indenture. In addition, the Company may, at its option, elect to cause
any Subsidiary that is not a Subsidiary Guarantor to guarantee payment of the Notes and become a Subsidiary Guarantor. 
 Section 415.
Purchase of Notes Upon a Change of Control. (a) Upon the occurrence after the Issue Date of a Change of Control, each Holder of Notes will have the right to require the Company to repurchase all or any part of such Notes at a purchase
price in cash equal to 101.0% of the principal amount thereof, plus accrued and unpaid interest, if any, to the date of repurchase (subject to the right of Holders of record on the relevant Regular Record Date to receive interest due on the relevant
Interest Payment Date falling prior to or on the purchase date and pursuant to Section 307); provided, however, that the Company shall not be obligated to repurchase Notes pursuant to this Section 415 in the
event that it has exercised its right to redeem all of the Notes as provided in Article X. 
 (b) In the event that, at the time of
such Change of Control, the terms of any Credit Facility Indebtedness constituting Designated Senior Indebtedness restrict or prohibit the repurchase of the Notes pursuant to this Section 415, then prior to the sending of the notice to
Holders provided for in Section 415(c) but in any event not later than 30 days following the date the Company obtains actual knowledge of any Change of Control (unless the Company has exercised its right to redeem all the Notes as
provided in Article X), the Company shall, or shall 

  
 98 








 
cause one or more of its Subsidiaries to, (i) repay in full all such Credit Facility Indebtedness subject to such terms or offer to repay in full all such Credit Facility Indebtedness
and repay the Credit Facility Indebtedness of each lender who has accepted such offer or (ii) obtain the requisite consent under the agreements governing such Credit Facility Indebtedness to permit the repurchase of the Notes as provided
for in Section 415(c). The Company shall first comply with the provisions of the immediately preceding sentence before it shall be required to repurchase Notes pursuant to the provisions set forth in this Section 415. The
Company’s failure to comply with the provisions of this Section 415(b) or Section 415(c) shall constitute an Event of Default under Section 601(iv) and not under Section 601(ii). 

(c) Unless the Company has exercised its right to redeem all the Notes as described in Article X, the Company shall, not later than
30 days following the date the Company obtains actual knowledge of any Change of Control having occurred, send a notice (a “Change of Control Offer”) to each Holder with a copy to the Trustee stating: (1) that a Change
of Control has occurred or may occur and that such Holder has, or upon such occurrence will have, the right to require the Company to purchase such Holder’s Notes at a purchase price in cash equal to 101.0% of the principal amount thereof, plus
accrued and unpaid interest, if any, to the date of purchase (subject to the right of Holders of record on a record date to receive interest on the relevant Interest Payment Date falling prior to or on the purchase date); (2) the
repurchase date (which shall be no earlier than 10 days nor later than 60 days from the date such notice is sent, except that such notice may be delivered more than 60 days prior to the purchase date if the purchase date is delayed as provided in
clause (4) of this Section 415(c)); (3) the instructions determined by the Company, consistent with this Section 415, that a Holder must follow in order to have its Notes purchased; and (4) if
such notice is sent prior to the occurrence of a Change of Control, that such offer is conditioned on the occurrence of such Change of Control and that the purchase date may, in the Company’s discretion, be delayed until such time as the Change
of Control has occurred. No Note will be repurchased in part if less than the Minimum Denomination in original principal amount of such Note would be left outstanding. 

(d) The Company will not be required to make a Change of Control Offer upon a Change of Control if a third party makes the Change of Control
Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Indenture applicable to a Change of Control Offer made by the Company and purchases all Notes validly tendered and not withdrawn under such Change
of Control Offer. 
 (e) If Holders of not less than 90% in aggregate principal amount of the outstanding Notes of any series 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 Section 415(d), purchases all of the Notes of such series validly
tendered and not withdrawn by such Holders, the Company or such third party will have the right, upon not less than 10 nor more than 60 days’ prior notice, given not more than 30 days following such purchase pursuant to such Change of Control
Offer, to redeem all Notes of such series that remain outstanding following such purchase at a price in cash equal to 101% of the principal amount thereof plus accrued and unpaid interest to but excluding the date of such redemption (subject to the
right of Holders of record on the relevant Regular Record Date to receive interest due on the relevant Interest Payment Date falling prior to or on the Redemption Date). 

  
 99 








 (f) The Company will comply, to the extent applicable, with the requirements of
Section 14(e) of the Exchange Act and any other securities laws or regulations in connection with the repurchase of Notes pursuant to this Section 415. To the extent that the provisions of any securities laws or regulations
conflict with the provisions of this Section 415, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 415 by virtue thereof.

 Section 416. Suspension of Covenants on Achievement of Investment Grade Rating. (a) If on any day following the Issue
Date (a) the Notes have Investment Grade Ratings from both Rating Agencies, and (b) no Default has occurred and is continuing under this Indenture, then, beginning on that day (the “Suspension Date”) subject
to the provisions of the following paragraph, the covenants listed under Section 407, Section 409, Section 410, Section 411, Section 412, Section 414,
Section 501(a)(iii) and Section 501(a)(iv) (collectively, the “Suspended Covenants”) will be suspended. During any period that the foregoing covenants have been suspended, the Board of Directors may not
designate any of the Company’s Subsidiaries as Unrestricted Subsidiaries unless such designation would have complied with Section 409 as if Section 409 would have been in effect during such period. 

(b) If on any subsequent date one or both of the Rating Agencies downgrade the ratings assigned to the Notes below an Investment Grade Rating,
the foregoing covenants will be reinstated as of and from the date of such rating decline (any such date, a “Reversion Date”). The period of time between the Suspension Date and the Reversion Date is referred to as the
“Suspension Period.” Upon such reinstatement, all Indebtedness Incurred during the Suspension Period will be deemed to have been Incurred under the exception provided by Section 407(b)(iii). With respect to Restricted
Payments made after any such reinstatement, the amount of Restricted Payments will be calculated as if Section 409 had been in effect prior to, but not during, the Suspension Period. For purposes of Section 411, upon the
occurrence of a Reversion Date the amount of Net Available Cash not applied in accordance with such covenant will be deemed to be reset to zero. In addition, for purposes of Section 412, all agreements and arrangements entered into by
the Company and any Restricted Subsidiary with an Affiliate of the Company during the Suspension Period prior to such Reversion Date will be deemed to have been entered into on or prior to the Issue Date, and for purposes of Section 410,
all contracts entered into during the Suspension Period prior to such Reversion Date that contain any of the encumbrances or restrictions subject to such covenant will be deemed to have been existing on the Issue Date. The Subsidiary Guarantees of
the Subsidiary Guarantors will be suspended during the Suspension Period. 

  
 100 








 (c) During the Suspension Period, any reference in the definitions of “Permitted Liens”
and “Unrestricted Subsidiary” to Section 407 or any provision thereof shall be construed as if such covenant were in effect during the Suspension Period. 

Notwithstanding that the Suspended Covenants may be reinstated, no Default or Event of Default will be deemed to have occurred as a result of
any actions taken by the Company or any Subsidiary (including for the avoidance of doubt any failure to comply with the Suspended Covenants) or other events that occurred during any Suspension Period (or upon termination of the Suspension Period or
after that time arising out of events that occurred or actions taken during the Suspension Period) and the Company and any Subsidiary will be permitted, without causing a Default or Event of Default or breach of any kind under this Indenture, to
honor, comply with or otherwise perform any contractual commitments or obligations entered into during a Suspension Period following a Reversion Date and to consummate the transactions contemplated thereby. 

(d) The Company shall deliver promptly to the Trustee an Officer’s Certificate notifying it of the occurrence of any Suspension Date or
any Reversion Date, but failure to so notify the Trustee shall not invalidate the occurrence of any Suspension Date or Reversion Date and shall not constitute a Default or Event of Default by the Company. The Trustee shall have no independent
obligation to determine if a Suspension Period has commenced or terminated or to notify Holders regarding the same. 
 ARTICLE V 

SUCCESSORS 

Section 501. When the Company May Merge, Etc. (a) The Company will not consolidate with or merge with or into, or convey,
lease or otherwise transfer all or substantially all its assets to, any Person, unless: 
 (i) the resulting, surviving or transferee Person
(the “Successor Company”) will be a Person organized and existing under the laws of the United States of America, any State thereof or the District of Columbia and the Successor Company (if not the Company) will expressly assume all
the obligations of the Company under the Notes and this Indenture by executing and delivering to the Trustee a supplemental indenture or one or more other documents or instruments; 

(ii) immediately after giving effect to such transaction (and treating any Indebtedness that becomes an obligation of the Successor Company or
any Restricted Subsidiary as a result of such transaction as having been Incurred by the Successor Company or such Restricted Subsidiary at the time of such transaction), no Default will have occurred and be continuing; 

  
 101 








 (iii) immediately after giving effect to such transaction, either (A) the Company
(or, if applicable, the Successor Company with respect thereto) could Incur at least $1.00 of additional Indebtedness pursuant to Section 407(a) or (B) the Consolidated Coverage Ratio of the Company (or, if applicable, the
Successor Company with respect thereto) would equal or exceed the Consolidated Coverage Ratio of the Company immediately prior to giving effect to such transaction; 

(iv) each Subsidiary Guarantor (other than (x) any Subsidiary Guarantor that will be released from its obligations under its
Subsidiary Guarantee in connection with such transaction and (y) any party to any such consolidation or merger) shall have delivered a supplemental indenture or other document or instrument, confirming its Subsidiary Guarantee (other
than any Subsidiary Guarantee that will be discharged or terminated in connection with such transaction); and 
 (v) the Company will have
delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each to the effect that such consolidation, merger or transfer complies with the provisions described in this Section 501(a), provided that
(x) in giving such opinion such counsel may rely on an Officer’s Certificate as to compliance with the foregoing clauses (ii) and (iii) and as to any matters of fact, and (y) no Opinion of Counsel will be
required for a consolidation, merger or transfer described in Section 501(b). 
 Any Indebtedness that becomes an obligation of
the Company (or, if applicable, the Successor Company with respect thereto) or any Restricted Subsidiary (or that is deemed to be Incurred by any Restricted Subsidiary that becomes a Restricted Subsidiary) as a result of any such transaction
undertaken in compliance with this Section 501, and any Refinancing Indebtedness with respect thereto, shall be deemed to have been Incurred in compliance with Section 407. 

(b) Clauses (ii) and (iii) of Section 501(a) will not apply to any transaction in which the Company consolidates or
merges with or into or transfers all or substantially all its properties and assets to (x) an Affiliate incorporated or organized for the purpose of reincorporating or reorganizing the Company in another jurisdiction or changing its
legal structure to a corporation or other entity or (y) a Restricted Subsidiary of the Company so long as all assets of the Company and the Restricted Subsidiaries immediately prior to such transaction (other than Capital Stock of such
Restricted Subsidiary) are owned by such Restricted Subsidiary and its Restricted Subsidiaries immediately after the consummation thereof. Section 501(a) will not apply to (1) any transaction in which any Restricted
Subsidiary consolidates with, merges into or transfers all or part of its assets to the Company or (2) the Transactions. 
 (c)
For purposes of this Section 501, so long as at the time of any Minority Business Disposition or any Minority Business Offering the Minority Business Disposition Condition is met, the Minority Business Assets shall not be deemed at any
time to constitute all or substantially all of the assets of the Company, and any sale or transfer of all or any part of the Minority Business Assets (whether directly or indirectly, whether by sale or transfer of any such assets, or of any Capital
Stock or other interest in any Person holding such assets, or any 

  
 102 








 
consolidation or merger, or any combination thereof, and whether in one or more transactions, or otherwise, including any Minority Business Offering or any Minority Business Disposition) shall
not be deemed at any time to constitute a consolidation with or merger with or into, or conveyance, transfer or lease of all or substantially all of the assets of the Company to, any Person. 

Section 502. Successor Company Substituted. Upon any transaction involving the Company in accordance with Section 501
in which the Company is not the Successor Company, the Successor Company will succeed to, and be substituted for, and may exercise every right and power of, the Company under this Indenture, and thereafter the predecessor Company shall be relieved
of all obligations and covenants under this Indenture, except that the predecessor Company in the case of a lease of all or substantially all its assets shall not be released from the obligation to pay the principal of and interest on the Notes.

 ARTICLE VI

(i) a default in any payment of interest on any Note when due, continued for a period of 30 days; 

(ii) a default in the payment of principal of any Note when due, whether at its Stated Maturity, upon optional redemption, upon
required repurchase, upon declaration of acceleration or otherwise;

obligations under Section 501(a); 
 (iv) the failure by the Company to comply for 30 days after the notice
specified in the penultimate paragraph of this Section 601 with any of its obligations under Section 415 (other than a failure to purchase the Notes); 

(v) the failure by the Company to comply for (x) 180 days after notice with any of its obligations under the
covenant described under Section 405 or (y) 60 days after the notice specified in the penultimate paragraph of this Section 601 with its other agreements contained in the Notes or this Indenture; 

(vi) the failure by any Subsidiary Guarantor to comply for 45 days after the notice specified in the penultimate paragraph of
this Section 601 with its obligations under its Subsidiary Guarantee; 

  
 103 








 (vii) the failure by the Company or any Restricted Subsidiary to pay any
Indebtedness for borrowed money (other than Indebtedness owed to the Company or any Restricted Subsidiary) within any applicable grace period after final maturity or the acceleration of any such Indebtedness by the holders thereof because of a
default, if the total amount of such Indebtedness so unpaid or accelerated exceeds $150.0 million or its foreign currency equivalent; provided that no Default or Event of Default will be deemed to occur with respect to any such Indebtedness
that is paid or otherwise acquired or retired (or for which such failure to pay or acceleration is waived or rescinded) within 20 Business Days after such failure to pay or such acceleration; 

(viii) the taking of any of the following actions by the Company or a Significant Subsidiary, pursuant to or within the meaning
of any Bankruptcy Law: 
 (A) the commencement of a voluntary case; 

(B) the consent to the entry of an order for relief against it in an involuntary case; 

(C) the consent to the appointment of a Custodian of it or for any substantial part of its property; or 

(D) the making of a general assignment for the benefit of its creditors; 

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

(A) is for relief against the Company or any Significant Subsidiary in an involuntary case; 

(B) appoints a Custodian of the Company or any Significant Subsidiary or for any substantial part of its property; or 

(C) orders the winding up or liquidation of the Company or any Significant Subsidiary; 

and the order or decree remains unstayed and in effect for 60 days; 

(x) the rendering of any judgment or decree for the payment of money in an amount (net of any insurance or indemnity payments
actually received in respect thereof prior to or within 90 days from the entry thereof, or to be received in respect thereof in the event any appeal thereof shall be unsuccessful) in excess of $150.0 million or its foreign currency equivalent
against the Company or a Significant Subsidiary that is not discharged, or bonded or insured by a third Person, if such judgment or decree remains outstanding for a period of 90 days following such judgment or decree and is not discharged, waived or
stayed; or 

  
 104 








 (xi) the failure of any Subsidiary Guarantee by a Subsidiary Guarantor that is a
Significant Subsidiary to be in full force and effect (except as contemplated by the terms thereof or of this Indenture) or the denial or disaffirmation in writing by any Subsidiary Guarantor that is a Significant Subsidiary of its obligations under
this Indenture or any Subsidiary Guarantee (other than by reason of the termination of this Indenture or such Subsidiary Guarantee or the release of such Subsidiary Guarantee in accordance with such Subsidiary Guarantee or this Indenture), if such
Default continues for 10 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. 

The term “Bankruptcy Law” means Title 11, United States Code, or any similar Federal, state or foreign law for the relief of
debtors. The term “Custodian” means any receiver, trustee, assignee, liquidator, custodian or similar official under any Bankruptcy Law. 

However, a Default under Section 601(iv), Section 601(v) or Section 601(vi) will not constitute
an Event of Default until the Trustee or the Holders of at least 30.0% in principal amount of the Outstanding Notes (which contain such Defaults) notify the Company in writing of the Default and the Company does not cure such Default within the time
specified in such clause after receipt of such notice. Such notice must specify the Default, demand that it be remedied and state that such notice is a “Notice of Default.” When a Default or an Event of Default is cured, it ceases.

 The Company shall deliver to the Trustee, within 30 days after the occurrence thereof, written notice in the form of an Officer’s
Certificate of any Event of Default under Section 601(vii) or Section 601(x) and any event that with the giving of notice or the lapse of time would become an Event of Default under Section 601(iv),
Section 601(v) or Section 601(vi), its status and what action the Company is taking or proposes to take with respect thereto. 

Section 602. Acceleration of Maturity; Rescission and Annulment. If an Event of Default (other than an Event of Default specified
in Section 601(viii) or Section 601(ix), with respect to the Company) occurs and is continuing, unless otherwise specified for Notes of any series in the applicable Notes Supplemental Indenture, as contemplated by
Section 301, the Trustee by written notice to the Company, or the Holders of at least 30.0% in principal amount of the Outstanding Notes (which contain such Defaults) by written notice to the Company and the Trustee, in either case
specifying in such notice the respective Event of Default and that such notice is a “notice of acceleration,” may declare the principal of and accrued but unpaid interest on all the Notes to be due and payable. Upon the effectiveness of
such a declaration, such principal and interest will be due and payable immediately. 

  
 105 








 Notwithstanding the foregoing, if an Event of Default specified in Section 601(viii)
or Section 601(ix), with respect to the Company, occurs and is continuing, unless otherwise specified for Notes of any series in the applicable Notes Supplemental Indenture, as contemplated by Section 301, the principal of
and accrued but unpaid interest on all the Outstanding Notes will ipso facto become immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. 

The Holders of a majority in principal amount of the Outstanding Notes (which contain such Event of Default which has been accelerated) by
notice to the Company and the Trustee may rescind an acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default have been cured or waived except non-payment of principal
or interest that has become due solely because of such acceleration. No such rescission shall affect any subsequent Default or impair any right consequent thereto. 

Section 603. Other Remedies; Collection Suit by Trustee. If an Event of Default occurs and is continuing, the Trustee may, but is
not obligated under this Section 603 to, pursue any available remedy to collect the payment of principal of or interest on the Notes or to enforce the performance of any provision of the Notes or this Indenture. If an Event of Default
specified in Section 601(i) or 601(ii) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company for the whole amount then due and owing (together with
interest on any unpaid interest to the extent lawful) and the amounts provided for in Section 707. 
 Section 604.
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 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 or applicable regulations, may vote on behalf of the Holders in any election of a trustee in bankruptcy or other Person performing
similar functions, and any Custodian in any such judicial proceeding is hereby authorized by each Holder to make 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 it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and its counsel, and any other amounts due the Trustee under Section 707. 

No provision of this Indenture shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder
any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 

  
 106 








 Section 605. Trustee May Enforce Claims Without Possession of Notes. 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 or the production 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 of the Notes in respect of which such judgment has been recovered. 
 Section 606.
Application of Money Collected. Any money or property collected by the Trustee pursuant to this Article VI shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such
money or property on account of principal (or premium, if any) or interest, upon presentation of the Notes and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid: 

First: to the payment of all amounts due the Trustee under Section 707; 

Second: to the payment of the amounts then due and unpaid upon the Notes for principal (and premium, if any) and
interest, in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Notes for principal (and premium, if any) and interest,
respectively; and 
 Third: to the Company. 

Section 607. Limitation on Suits. Subject to Section 608, no Holder may pursue any remedy with respect to this
Indenture or the Notes unless: 
 (i) such Holder has previously given the Trustee written notice that an Event of Default is
continuing; 
 (ii) Holders of at least 30.0% in principal amount of the Outstanding Notes (which contain such Event of
Default) have requested the Trustee in writing to pursue the remedy; 
 (iii) such Holder or Holders have offered to the
Trustee security or indemnity satisfactory to it against any loss, liability or expense; 
 (iv) the Trustee has not complied
with the request within 60 days after receipt of the request and the offer of security or indemnity; and 
 (v) the
Holders of a majority in principal amount of the Outstanding Notes have not given the Trustee a written direction inconsistent with the request within such 60-day period. 

  
 107 








 A Holder may not use this Indenture to affect, disturb or prejudice the rights of another Holder,
to obtain a preference or priority over another Holder or to enforce any right under this Indenture except in the manner herein provided and for the equal and ratable benefit of all Holders. 

Section 608. [Reserved]. 

Section 609. Restoration of Rights and Remedies. If the Trustee or any Holder has instituted any proceeding to enforce any right
or remedy under this Indenture or any Note and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case the Company, any other obligor upon the
Notes, the Trustee and the Holders shall, subject to any determination in such proceeding, be restored severally and respectively to their former positions hereunder, and thereafter all rights and remedies of the Trustee and the Holders shall
continue as though no such proceeding had been instituted. 
 Section 610. Rights and Remedies Cumulative. No right or remedy
herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and
remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right
or remedy. 
 Section 611. Delay or Omission Not Waiver. No delay or omission of the Trustee or of any Holder of any Note to
exercise any right or remedy accruing upon any 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 VI 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. 

Section 612. Control by Holders. The Holders of not less than a majority in aggregate principal amount of the Outstanding Notes
(which contain the Event of Default for which a remedy is being enforced) shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on
the Trustee, provided that 
 (1) such direction shall not be in conflict with any rule of law or with this Indenture,
and 

  
 108 








 (2) the Trustee may take any other action deemed proper by the Trustee which is
not inconsistent with such direction. 
 However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture
or, subject to Section 701, that the Trustee determines is unduly prejudicial to the rights of any other Holder or that would involve the Trustee in personal liability; provided, however, that the Trustee may take any other
action deemed proper by the Trustee that is not inconsistent with such direction. Prior to taking any action under this Indenture, the Trustee shall be entitled to indemnification satisfactory to it in its sole discretion against all losses and
expenses caused by taking or not taking such action. 
 Section 613. Waiver of Past Defaults. The Holders of not less than a
majority in aggregate principal amount of the Outstanding Notes (which contain such Default) may on behalf of the Holders of all the Notes waive any past Default hereunder and its consequences, except a Default 

(1) in the payment of principal of or interest on any Note (which may only be waived with the consent of each Holder of Notes
affected), or 
 (2) in respect of a covenant or provision hereof that pursuant to the second paragraph of
Section 902 cannot be modified or amended without the consent of the Holder of each Outstanding Note affected. 
 Upon any such
waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or Event of Default or
impair any right consequent thereon. In case of any such waiver, the Company, any other obligor upon the Notes, the Trustee and the Holders shall be restored to their former positions and rights hereunder and under the Notes, respectively. 

Section 614. Undertaking for Costs. All parties to this Indenture agree, and each Holder of any Note by such Holder’s
acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture or the Notes, or in any suit against the Trustee for any action taken,
suffered or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees,
against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant. This Section 614 shall not apply to any suit instituted by the Trustee, to any suit instituted
by any Holder, or group of Holders, holding in the aggregate more than 10.0% in principal amount of the Outstanding Notes (which contain the applicable Event of Default), or to any suit instituted by any Holder for the enforcement of the payment of
principal of (or premium, if any) or interest on any Note on or after the respective Stated Maturity or Interest Payment Dates expressed in such Note. 

  
 109 








 Section 615. Waiver of Stay, Extension or Usury Laws. The Company agrees (to the
extent that it may lawfully do so) that it shall not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law or any usury or other similar law wherever enacted, now or at
any time hereafter in force, that would prohibit or forgive the Company from paying all or any portion of the principal of (or premium, if any) or interest on the Notes contemplated herein or in the Notes or that may affect the covenants or the
performance of this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and shall not 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 had been enacted. 
 ARTICLE VII 

THE TRUSTEE 

Section 701. Certain Duties and Responsibilities. (a) Except during the continuance of an Event of Default, 

(1) the Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Indenture, and no
implied covenants or obligations shall be read into this Indenture against the Trustee; and 
 (2) in the absence of bad
faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this
Indenture; but in the case of any such certificates or opinions that 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 verify the contents thereof. 
 (b) In case an Event of Default has occurred and is
continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise as a prudent person would exercise or use under the circumstances in the conduct of such
person’s own affairs. 
 (c) No provision of this Indenture shall be construed to relieve the Trustee from liability for its own
negligent action, its own negligent failure to act, or its own willful misconduct, except that (i) this paragraph does not limit the effect of Section 701(a); (ii) the Trustee shall not be liable for any error of
judgment made in good faith by a Trust Officer, unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; and (iii) the Trustee shall not be liable with respect to any action it takes or omits to take in
good faith in accordance with a direction received by it pursuant to Section 612. 

  
 110 








 (d) No provision of this Indenture shall require the Trustee to expend or risk its own funds or
otherwise incur financial liability in the performance of any of its duties hereunder or in the exercise of any of its rights or powers, if repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it.

 (e) Whether or not therein expressly so provided, every provision of this Indenture relating to the conduct or affecting the liability of
or affording protection to the Trustee shall be subject to the provisions of this Section 701 and Section 703. 

Section 702. Notice of Defaults. If a Default occurs and is continuing and is known to the Trustee, the Trustee must send within
90 days after it occurs, to all Holders as their names and addresses appear in the Note Register, notice of such Default hereunder known to the Trustee unless such Default shall have been cured or waived; provided, however, that,
except in the case of a Default in the payment of principal of, or premium, if any, or interest on any Note, the Trustee shall be protected in withholding such notice if and so long as the board of directors, the executive committee or a trust
committee of Responsible Officers of the Trustee in good faith determines that the withholding of such notice is in the interests of the Holders. 

Section 703. Certain Rights of Trustee. Subject to the provisions of Section 701: 

(1) the Trustee may rely and shall be protected in acting or refraining from acting upon any resolution, certificate,

Company;

 111 








 (5) the Trustee shall be under no obligation to exercise any of the rights or
powers vested in it by this Indenture at the request or direction of any of the Holders pursuant to this Indenture, unless such Holders shall have offered to the Trustee security or indemnity satisfactory to it against the costs, expenses and
liabilities which might be incurred by it in compliance with such request or direction;

(9) the permissive rights of the Trustee to do things enumerated in this Indenture shall not be construed as a duty unless so
specified herein. 
 Section 704. Not Responsible for Recitals or Issuance of Notes. The recitals contained herein and in the
Notes, except the Trustee’s certificates of authentication, shall be taken as the statements of the Company, and neither the Trustee nor any Authenticating Agent assumes any responsibility for their correctness. The Trustee makes no
representations as to the validity or sufficiency of this Indenture or of the Notes, except that the Trustee represents that it is duly authorized to execute and deliver this Indenture, authenticate the Notes and perform its obligations hereunder
and that the statements made by it in a Statement of Eligibility and Qualification on Form T-1 supplied to the Company and any other obligor upon the Notes in connection with the registration of any Notes or Subsidiary Guarantees issued hereunder
are and will be true and accurate subject to the qualifications set forth therein. Neither the Trustee nor any Authenticating Agent shall be accountable for the use or application by the Company of the Notes or the proceeds thereof. 

Section 705. May Hold Notes. The Trustee, any Authenticating Agent, any Paying Agent, any Note Registrar or any other agent
of the Company, in its individual or any other capacity, may become the owner or pledgee of Notes and, subject to Section 708 and Section 713, may otherwise deal with the Company or its Affiliates with the same rights it
would have if it were not Trustee, Authenticating Agent, Paying Agent, Note Registrar or such other agent. 

  
 112 








 Section 706. Money Held in Trust. Money held by the Trustee in trust hereunder need
not be segregated from other funds except to the extent required by law. The Trustee shall be under no liability for interest on any money received by it hereunder except as otherwise agreed in writing with the Company. 

Section 707. Compensation and Reimbursement. The Company agrees, 

(1) to pay to the Trustee from time to time the reasonable compensation agreed to by the Company in writing for all services
rendered by the Trustee hereunder (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust); 

(2) except as otherwise expressly provided herein, to reimburse the Trustee upon its request for all reasonable out-of-pocket

attributable to its negligence or willful misconduct; and 
 (3) to indemnify the Trustee for, and to hold it harmless
against, any loss, liability or expense incurred without negligence or willful misconduct on the Trustee’s part, arising out of or in connection with the administration of the trust or trusts hereunder, including the costs and expenses of
defending itself against any claim or liability in connection with the exercise or performance of any of its powers or duties hereunder. 
 The Company need
not pay for any settlement made without its consent (which consent shall not be unreasonably withheld). The provisions of this Section 707 shall survive the termination of this Indenture or the resignation and removal of the Trustee.

 The Trustee shall have a claim prior to the Notes for payment of all amounts due the Trustee under this Section 707 on all
money or property held or collected by the Trustee, other than money or property held in trust to pay the principal of and interest on any Notes. 

Section 708. Conflicting Interests. If the Trustee has or shall acquire a conflicting interest within the meaning of the TIA, the
Trustee shall eliminate such interest, apply to the SEC for permission to continue as Trustee with such conflict or resign, to the extent and in the manner provided by, and subject to the provisions of, the TIA and this Indenture. The Trustee shall
not be deemed to have a conflicting interest by virtue of being a trustee under this Indenture with respect to Initial Notes and Additional Notes, or a trustee under any other indenture between the Company and the Trustee. 

  
 113 








 Section 709. Corporate Trustee Required; Eligibility. There shall at all times be one
(and only one) Trustee hereunder. The Trustee shall be a Person that is eligible pursuant to the TIA to act as such and has a combined capital and surplus of at least $50.0 million. If any such Person publishes reports of condition at least
annually, pursuant to law or to the requirements of its supervising or examining authority, then for the purposes of this Section 709 and to the extent permitted by the TIA, the combined capital and surplus of such Person shall be deemed
to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section 709, it shall resign
immediately in the manner and with the effect hereinafter specified in this Article. 
 Section 710. Resignation and Removal;
Appointment of Successor. No resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this Article shall become effective until the acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 711. 
 The Trustee may resign at any time by giving written notice thereof to the Company.
If the instrument of acceptance by a successor Trustee required by Section 711 shall not have been delivered to the Trustee within 30 days after the giving of such notice of resignation, the resigning Trustee may petition any court
of competent jurisdiction for the appointment of a successor Trustee. 
 The Trustee may be removed at any time by Act of the Holders of a
majority in principal amount of the Outstanding Notes delivered to the Trustee and to the Company. 
 If at any time: 

(1) the Trustee shall fail to comply with Section 708 after written request therefor by the Company or by any
Holder who has been a bona fide Holder of a Note for at least six months, or 
 (2) the Trustee shall cease to be eligible
under Section 709 and shall fail to resign after written request therefor by the Company or by any such Holder, or 

(3) the Trustee shall become incapable of acting or shall be adjudged bankrupt or insolvent or a receiver of the Trustee or of
its property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, 

then, in any such case, (A) the Company may remove the Trustee, or (B) subject to Section 614, any Holder who has been a
bona fide Holder of a Note for at least six months may, on behalf of itself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 

  
 114 








 If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall
occur in the office of Trustee for any cause, the Company shall promptly appoint a successor Trustee and shall comply with the applicable requirements of Section 711. If, within one year after such resignation, removal or incapability,
or the occurrence of such vacancy, a successor Trustee shall be appointed by Act of the Holders of a majority in principal amount of the Outstanding Notes delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall,
forthwith upon its acceptance of such appointment in accordance with the applicable requirements of Section 711, become the successor Trustee and to that extent supersede the successor Trustee appointed by the Company. If no successor
Trustee shall have been so appointed by the Company or the Holders and accepted appointment in the manner required by Section 711, then, subject to Section 614, any Holder who has been a bona fide Holder of a Note for at
least six months may, on behalf of itself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee. 

The Company shall give notice of each resignation and each removal of the Trustee and each appointment of a successor Trustee to all Holders
in the manner provided in Section 110. Each notice shall include the name of the successor Trustee and the address of its Corporate Trust Office. 

Notwithstanding the replacement of the Trustee pursuant to this Section 710, the Company’s obligations under
Section 707 shall continue for the benefit of the retiring Trustee. 
 Section 711. Acceptance of Appointment by
Successor. In case of the appointment hereunder of a successor Trustee, every such successor Trustee so appointed shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and
thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee;
but, on the request of the Company or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee
and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder. 

Upon request of any such successor Trustee, the Company shall execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Trustee all such rights, powers and trusts referred to above. 
 No successor Trustee shall accept its
appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible under this Article VII. 

  
 115 








 Section 712. Merger, Conversion, Consolidation or Succession to Business. Any
corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all
or substantially all the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such corporation shall be otherwise qualified and eligible under this Article VII, without the execution
or filing of any paper or any further act on the part of any of the parties hereto. In case any Notes shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such
authenticating Trustee may adopt such authentication and deliver the Notes so authenticated with the same effect as if such successor Trustee had itself authenticated such Notes. 

Section 713. Preferential Collection of Claims Against the Company. If and when the Trustee shall be or become a creditor of the
Company (or any other obligor upon the Notes), the Trustee shall be subject to the provisions of the TIA regarding the collection of claims against the Company (or any such other obligor) or realizing on certain property received by it in respect of
such claims. 
 Section 714. Appointment of Authenticating Agent. The Trustee may appoint an Authenticating Agent acceptable to
the Company to authenticate the Notes. Any such appointment shall be evidenced by an instrument in writing signed by a Trust Officer, a copy of which instrument shall be promptly furnished to the Company. Unless limited by the terms of such
appointment, an Authenticating Agent may authenticate Notes whenever the Trustee may do so. Each reference in this Indenture to authentication (or execution of a certificate of authentication) by the Trustee includes authentication (or execution of
a certificate of authentication) by such Authenticating Agent. An Authenticating Agent has the same rights as any Note Registrar, Paying Agent or agent for service of notices and demands. 

ARTICLE VIII 
 HOLDERS’ LISTS
AND REPORTS BY 
 TRUSTEE AND THE COMPANY 

Section 801. The Company to Furnish Trustee Names and Addresses of Holders. The Company will furnish or cause to be furnished to
the Trustee 
 (1) semi-annually, not more than 10 days after each Regular Record Date, a list, in such form as the Trustee
may reasonably require, of the names and addresses of the Holders of such series as of such Regular Record Date, and 

  
 116 








 (2) at such other times as the Trustee may request in writing, within
30 days after the receipt by the Company of any such request, a list of similar form and content as of a date not more than 15 days prior to the time such list is furnished; 

provided, however, that if and to the extent and so long as the Trustee shall be the Note Registrar, no such list need be furnished pursuant to
this Section 801. 
 Section 802. Preservation of Information; Communications to Holders. The Trustee shall
preserve, in as current a form as is reasonably practicable, the names and addresses of Holders contained in the most recent list, if any, furnished to the Trustee as provided in Section 801 and the names and addresses of Holders
received by the Trustee in its capacity as Note Registrar; provided, however, that if and so long as the Trustee shall be the Note Registrar, the Note Register shall satisfy the requirements relating to such list. None of the Company,
any Subsidiary Guarantor or the Trustee or any other Person shall be under any responsibility with regard to the accuracy of such list. The Trustee may destroy any list furnished to it as provided in Section 801 upon receipt of a new
list so furnished. 
 The rights of Holders to communicate with other Holders with respect to their rights under this Indenture or under the
Notes, and the corresponding rights and privileges of the Trustee, shall be as provided by the TIA. 
 Every Holder of Notes, by receiving
and holding the same, agrees with the Company and the Trustee that neither the Company, nor the Trustee, nor any agent of any of them, shall be held accountable by reason of any disclosure of information as to names and addresses of Holders made
pursuant to the TIA. 
 Section 803. Reports by Trustee. Within 60 days after each December 1, beginning with
December 1, 2017, the Trustee shall transmit to Holders such reports concerning the Trustee and its actions under this Indenture as may be required pursuant to the TIA at the times and in the manner provided pursuant thereto for so long as any
Notes remain outstanding. A copy of each such report shall, at the time of such transmission to Holders, be filed by the Trustee or any applicable listing agent with each stock exchange upon which any Notes are listed, with the SEC and with the
Company. The Company shall notify the Trustee in writing when any Notes are listed on any stock exchange, but any failure to so notify the Trustee shall not constitute a Default or Event of Default by Company. 

ARTICLE IX 
 AMENDMENT,
SUPPLEMENT OR WAIVER 
 Section 901. Without Consent of Holders. Without the consent of the Holders of any Notes, the
Company, the Trustee and (as applicable) any Subsidiary Guarantor may amend or supplement this Indenture or the Notes for any of the following purposes: 

(1) to cure any ambiguity, mistake, omission, defect or inconsistency, 

  
 117 








 (2) to provide for the assumption by a successor of the obligations of the
Company, or a Subsidiary Guarantor under this Indenture or the Notes, 
 (3) to provide for uncertificated Notes in addition
to or in place of certificated Notes, 
 (4) to secure the Notes, 

(5) to evidence a successor Trustee, 

(6) to add Guarantees with respect to the Notes, or to confirm and evidence the release, termination or discharge of any
Guarantee or Lien with respect to or securing the Notes when such release, termination or discharge is provided for under this Indenture or the Notes, 

(7) to add to the covenants of the Company for the benefit of the Holders or to surrender any right or power conferred upon the
Company, 
 (8) to provide for or confirm the issuance of Initial Notes or Additional Notes, 

(9) to conform the text of this Indenture (including any supplemental indenture or any other instrument pursuant to which
Additional Notes are issued), the Notes (including any Additional Notes), or any Subsidiary Guarantee to any provision of the “Description of Notes” section of the Offering Memorandum, or, with respect to any Additional Notes and any
supplemental indenture or other instrument pursuant to which such Additional Notes are issued, to the “Description of Notes” section of the offering memorandum relating to the issuance of such Additional Notes solely to the extent that
such “Description of Notes” section provides for terms of such Additional Notes that differ from the terms of the Initial Notes, in accordance with Section 301, 

(10) to increase the minimum denomination of the Notes to equal the dollar equivalent of €1,000 rounded up to the nearest
$1,000 (including for purposes of redemption or repurchase of any Note in part), 
 (11) to make any change that does not
materially adversely affect the rights of any Holder under the Notes or this Indenture, or 
 (12) to comply with any
requirement of the SEC in connection with the qualification of this Indenture under the TIA or otherwise. 

  
 118 








 Section 902. With Consent of Holders. Subject to Section 608, the
Company, the Trustee and (as applicable) any Subsidiary Guarantor may amend or supplement this Indenture or the Notes with the written consent of the Holders of not less than a majority in aggregate principal amount of the Outstanding Notes
(including consents obtained in connection with a tender offer or exchange offer for Notes) and the Holders of not less than a majority in aggregate principal amount of the Outstanding Notes by written notice to the Trustee (including consents
obtained in connection with a tender offer or exchange offer for Notes) may waive any existing Default or Event of Default or compliance by the Company, or any Subsidiary Guarantor with any provision of this Indenture, the Notes or any Subsidiary
Guarantee; provided that (x) if any such amendment or waiver will only affect one series of Notes (or less than all series of Notes) then outstanding under this Indenture, then only the consent of the Holders of a majority in
principal amount of the Notes of such series then outstanding (including, in each case, consents obtained in connection with a tender offer or exchange offer for Notes) shall be required and (y) if any such amendment or waiver by its
terms will affect a series of Notes in a manner different and materially adverse relative to the manner such amendment or waiver affects other series of Notes, then the consent of the Holders of a majority in principal amount of the Notes of such
series then outstanding (including, in each case, consents obtained in connection with a tender offer or exchange offer for Notes) shall be required. 

Notwithstanding the provisions of this Section 902, without the consent of each Holder affected, an amendment or waiver, including
a waiver pursuant to Section 613, may not: 
 (i) reduce the principal amount of the Notes whose Holders must
consent to an amendment or waiver; 
 (ii) reduce the rate of or extend the time for payment of interest on any Note; 

(iii) reduce the principal of or extend the Stated Maturity of any Note; 

(iv) reduce the premium payable upon the redemption of any Note or change the date on which any Note may be redeemed as
described in Section 6 of the applicable Notes Supplemental Indenture; 
 (v) make any Note payable in money other than
that stated in such Note; 
 (vi) amend or waive the legal right of any Holder of any Note to receive payment of principal of
and interest on such Note on or after the respective Stated Maturity for such principal or Interest Payment Date for such interest expressed in such Note, or to institute suit for the enforcement of any such payment on or after such respective
Stated Maturity or Interest Payment Date; or 
 (vii) make any change in the amendment or waiver provisions described in this
paragraph. 

  
 119 








 It shall not be necessary for the consent of the Holders under this Section 902 to
approve the particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if such consent approves the substance thereof. 

After an amendment, supplement or waiver under this Section 902 becomes effective, the Company shall send to the Holders, with a
copy to the Trustee, a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to send such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any supplemental indenture
or the effectiveness of any such amendment, supplement or waiver. 
 Section 903. Execution of Amendments, Supplements or
Waivers. The Trustee shall sign any amendment, supplement or waiver authorized pursuant to this Article IX if the amendment, supplement or waiver does not adversely affect the rights, duties, liabilities or immunities of the Trustee.
If it does, the Trustee may, but need not, sign it. In signing or refusing to sign such amendment, supplement or waiver, the Trustee shall be entitled to receive, and shall be fully protected in relying upon, an Officer’s Certificate and an
Opinion of Counsel to the effect that the execution of such amendment, supplement or waiver is authorized or permitted or complies with this Indenture, that all conditions precedent to such amendment, supplement or waiver required by this Indenture
have been complied with and that such amendment, supplement or waiver is a valid and binding agreement of the Company, enforceable against the Company in accordance with its terms. For the avoidance of doubt, no Officer’s Certificate or Opinion
of Counsel shall be required on the Issue Date for the execution of any Note Supplemental Indenture, supplemental indenture pursuant to Section 501(a)(i) or Guarantor Supplemental Indenture. 

Section 904. Revocation and Effect of Consents. Until an amendment, supplement or waiver becomes effective, a consent to it by a
Holder is a continuing consent by the Holder and every subsequent Holder of that Note or any Note that evidences all or any part of the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note. Subject
to the following paragraph of this Section 904, any such Holder or subsequent Holder may revoke the consent as to such Holder’s Note by written notice to the Trustee or the Company, received by the Trustee or the Company, as the
case may be, before the date on which the Trustee receives an Officer’s Certificate from the Company certifying that the Holders of the requisite principal amount of Notes have consented (and not theretofore revoked such consent) to the
amendment, supplement or waiver. 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 as set forth in Section 108. 

After an amendment, supplement or waiver becomes effective, it shall bind every Holder of Notes, unless it makes a change described in any of
clauses (i) through (vii) of the second paragraph of Section 902. In that case, the amendment, supplement or waiver shall bind each Holder of a Note who has consented to it and every subsequent Holder of such Note or any Note
that evidences all or any part of the same debt as the consenting Holder’s Note. 

  
 120 








 Section 905. [Reserved]. 

Section 906. Notation on or Exchange of Notes. If an amendment, supplement or waiver changes the terms of a Note, the Trustee
shall (if required by the Company and in accordance with the specific direction of the Company) request the Holder of the Note to deliver it to the Trustee. The Trustee shall (if required by the Company and in accordance with the specific direction
of the Company) 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. 

ARTICLE X 
 REDEMPTION OF NOTES

 Section 1001. Applicability of Article. Notes of or within any series that are redeemable in whole or in part before
their Stated Maturity shall be redeemable in accordance with their terms and (except as otherwise specified for Notes of any series in the applicable Notes Supplemental Indenture, as contemplated by Section 301) in accordance with this
Article X. 
 Section 1002. [Reserved]. 

Section 1003. Election to Redeem; Notice to Trustee. In case of any redemption at the election of the Company of less than all of

of Notes pursuant to Section 1201 or satisfaction and discharge of this Indenture pursuant to Section 1101 or if the Redemption Date is delayed as provided in Section 6 of the applicable Notes Supplemental Indenture)
prior to the date on which notice is required to be sent or caused to be sent to Holders pursuant to Section 1005, notify the Trustee of such Redemption Date and of the principal amount of Notes to be redeemed, but failure to so notify
the Trustee shall not invalidate any notice given in accordance with Section 1005 and shall not constitute a Default or Event of Default by the Company. 

  
 121 








 Section 1004. Selection by Trustee of Notes to Be Redeemed. Unless otherwise
specified for Notes of any series in the applicable Notes Supplemental Indenture, as contemplated by Section 301, in the case of any partial redemption, selection of the Notes for redemption will be made by the Trustee not more than 60
days prior to the Redemption Date (except that such notice may be delivered more than 60 days prior to the Redemption Date if such notice is issued in connection with the defeasance of Notes pursuant to Section 1201 or a satisfaction and
discharge of this Indenture pursuant to Section 1101 or if the Redemption Date is delayed as provided in Section 6 of the applicable Notes Supplemental Indenture) on a pro rata basis, by lot or by such other method as the
Trustee shall deem to be fair and appropriate, and in the case of global notes, in accordance with the procedures of the Depositary, in integral multiples of $1,000, although no Note of the Minimum Denomination in original principal amount or less
will be redeemed in part. 
 The Trustee shall promptly notify the Company in writing of the Notes selected for redemption and, in the case
of any Note selected for partial redemption, the principal amount thereof to be redeemed. On and after the Redemption Date, interest will cease to accrue on Notes or portions thereof called for redemption. 

For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Notes shall relate, in
the case of any Note redeemed or to be redeemed only in part, to the portion of the principal amount of such Note that has been or is to be redeemed. 

Section 1005. Notice of Redemption. Subject to the final paragraph of Section 110, unless otherwise specified for
Notes of any series in the applicable Notes Supplemental Indenture, as contemplated by Section 301, notice of redemption or purchase as provided in Section 1001 shall be given electronically or, at the Company’s option,
by first-class mail, postage prepaid, sent not less than 10 nor more than 60 days prior to the Redemption Date (except that such notice may be delivered more than 60 days prior to the Redemption Date if such notice is issued in connection with the
defeasance of Notes pursuant to Section 1201 or satisfaction and discharge of this Indenture pursuant to Section 1101 or if the Redemption Date is delayed as provided in Section 6 of the applicable Notes Supplemental
Indenture) to each Holder of Notes to be redeemed, at such Holder’s address appearing in the Note Register. 
 Any such notice shall
state: 
 (1) the expected Redemption Date, 

(2) the redemption price (or the formula by which the redemption price will be determined), 

  
 122 








 (3) if less than all Outstanding Notes are to be redeemed, the identification
(and, in the case of partial redemption, the portion of the respective principal amounts) of the Notes to be redeemed, 
 (4)
that, on the Redemption Date, the redemption price will become due and payable upon each such Note, and that, unless the Company defaults in making such redemption payment or the Paying Agent is prohibited from making such payment pursuant to the
terms of this Indenture, interest thereon shall cease to accrue from and after said date, and 
 (5) the place where such
Notes are to be surrendered for payment of the redemption price. 
 In addition, if such redemption, purchase or notice is subject to satisfaction (or,
waiver by the Company in its sole discretion) of one or more conditions precedent, as permitted by Section 6 of the applicable Notes Supplemental Indenture, such notice shall describe each such condition, and if applicable, shall state that, in
the Company’s discretion, the Redemption Date may be delayed until such time as any or all such conditions shall be satisfied (or waived by the Company in its sole discretion), or such redemption or purchase may not occur and such notice may be
rescinded in the event that any or all such conditions shall not have been (or, in the Company’s sole determination, may not be) satisfied (or waived by the Company in its sole discretion) by the Redemption Date, or by the Redemption Date as so
delayed. 
 The Company may provide in such notice that payment of the redemption price and the performance of the Company’s
obligations with respect to such redemption may be performed by another Person. 
 Notice of such redemption or purchase of Notes to be so
redeemed or purchased at the election of the Company shall be given by the Company or, at the Company’s request (made to the Trustee at least 15 days (or such shorter period as shall be reasonably satisfactory to the Trustee) prior to the
Redemption Date), by the Trustee in the name and at the expense of the Company. Any such request will set forth the information to be stated in such notice, as provided by this Section 1005. 

The notice if sent in the manner herein provided shall be conclusively presumed to have been given, whether or not the Holder receives such
notice. In any case, failure to give or send or any defect in the notice to the Holder of any Note designated for redemption as a whole or in part shall not affect the validity of the proceedings for the redemption of any other Note. 

Section 1006. Deposit of Redemption Price. Unless otherwise specified for Notes of any series in the applicable Notes Supplemental
Indenture, as contemplated by Section 301, on or prior to 12:00 p.m., New York City time, on any Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the


  
 123 








 
Company is acting as its own Paying Agent, the Company shall segregate and hold in trust as provided in Section 403) an amount of money sufficient to pay the redemption price of, and
any accrued and unpaid interest on, all the Notes or portions thereof which are to be redeemed on that date. 
 Section 1007. Notes
Payable on Redemption Date. Notice of redemption having been given as provided in this Article X or in the applicable Notes Supplemental Indenture, the Notes so to be redeemed shall, on the Redemption Date, become due and payable at
the redemption price specified herein or in the applicable Notes Supplemental Indenture and from and after such date (unless the Company shall default in the payment of the redemption price or the Paying Agent is prohibited from paying the
redemption price pursuant to the terms of this Indenture) such Notes shall cease to bear interest. Upon surrender of such Notes for redemption in accordance with such notice, such Notes shall be paid by or on behalf of the Company at the redemption
price. Installments of interest whose Interest Payment Date is on or prior to the Redemption Date shall be payable to the Holders of such Notes registered as such on the relevant Regular Record Dates according to their terms and the provisions of
Section 307. 
 On and after any Redemption Date, if money sufficient to pay the redemption price of and any accrued and unpaid
interest on Notes called for redemption shall have been made available in accordance with Section 1006, the Notes (or the portions thereof) called for redemption will cease to accrue interest and the only right of the Holders of such
Notes (or portions thereof) will be to receive payment of the redemption price of and, subject to the last sentence of the preceding paragraph, any accrued and unpaid interest on such Notes (or portions thereof) to the Redemption Date. If any Note
(or portion thereof) called for redemption shall not be so paid upon surrender thereof for redemption, the principal (and premium, if any) shall, until paid, bear interest from the Redemption Date at the rate borne by the Note (or portion thereof).

 Section 1008. Notes Redeemed in Part. Any Note that is to be redeemed only in part shall be surrendered at the Place of
Payment (with due endorsement by, or a written instrument of transfer in form satisfactory to the Company duly executed by, the Holder thereof or its attorney duly authorized in writing) and the Company shall execute and (upon receipt of an
Authentication Order) the Trustee shall authenticate and deliver to the Holder of such Note without service charge, a new Note or Notes, of any authorized denomination as requested by such Holder in aggregate principal amount equal to and in
exchange for the unredeemed portion of the principal of the Note so surrendered (or if the Note is a Global Note, an adjustment shall be made to the schedule attached thereto).

from other funds except to the extent required by law.

 ARTICLE XII

DEFEASANCE OR COVENANT DEFEASANCE 

Section 1201. The Company’s Option to Effect Defeasance or Covenant Defeasance. The Company may, at its option, at any time,
elect to have terminated the obligations of the Company with respect to Outstanding Notes and to have terminated all of the obligations of the Subsidiary Guarantors with respect to the Subsidiary Guarantees, in each case, as set forth in this
Article XII, and elect to have either Section 1202 or Section 1203 be applied to all of the Outstanding Notes (the “Defeased Notes”), upon compliance with the conditions set forth below in
Section 1204. Either Section 1202 or Section 1203 may be applied to the Defeased Notes to any Redemption Date or the Stated Maturity of the Notes. 

Section 1202. Defeasance and Discharge. Upon the Company’s exercise under Section 1201 of the option applicable
to this Section 1202, the Company shall be deemed to have been released and discharged from its obligations with respect to the Defeased Notes and the Subsidiary Guarantors shall be deemed to have been released and discharged from their
obligations with respect to the Subsidiary Guarantees on the date the relevant conditions set forth in Section 1204 are satisfied (hereinafter, “Defeasance”). For this purpose, such Defeasance means that the Company
shall be deemed to have paid and discharged the entire Indebtedness represented by the Defeased Notes, which shall thereafter be deemed to be “Outstanding” only for the purposes of Section 1205 and the other Sections of this
Indenture referred to in clauses (a) and (b) below, and the Company, and each of the Subsidiary Guarantors shall be deemed to have satisfied all other obligations under such Notes, Subsidiary Guarantees and this Indenture insofar as such
Notes are concerned (and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following, which shall survive until otherwise terminated or discharged hereunder: (a) the
rights of Holders of Defeased Notes to receive, solely from the trust fund described in Section 1204 and as more fully set forth in such Section, payments in respect of principal of and premium, if any, and interest on such Notes when
such payments are due, (b) the Company’s obligations with respect to such Defeased Notes under Sections 304, 305, 306, 402, and 403, (c) the rights, powers, trusts, duties and
immunities of the Trustee hereunder, including the Trustee’s rights (and the Company’s obligations) under Section 707, and (d) this Article XII. If the Company exercises its option under this
Section 1202, payment of the Notes may not be accelerated because of an Event of Default with respect thereto. Subject to compliance with this Article XII, the Company may, at its option and at any time, exercise its option
under this Section 1202 notwithstanding the prior exercise of its option under Section 1203 with respect to the Notes. 

Section 1203. Covenant Defeasance. Upon the Company’s exercise under Section 1201 of the option applicable to
this Section 1203, (a) the Company and the 

  
 128 








 
Subsidiary Guarantors shall be released from its obligations under any covenant or provision contained in Section 405, Sections 407 through 415, and the provisions
of clauses (iii), (iv) and (v) of Section 501(a) shall not apply, and (b) the occurrence of any event specified in clause (iv), (v) (with respect to Section 405, Sections 407
through 415, inclusive), (vi), (vii), (viii) (with respect to Subsidiaries), (ix) (with respect to Subsidiaries), (x) or (xi) of Section 601 shall be deemed not to be or result in an Event of Default, in each
case with respect to the Defeased Notes on and after the date the conditions set forth below are satisfied (hereinafter, “Covenant Defeasance”), and the Notes shall thereafter be deemed not to be “Outstanding” for the
purposes of any direction, waiver, consent or declaration or Act of Holders (and the consequences of any thereof) in connection with such covenants or provisions, but shall continue to be deemed “Outstanding” for all other purposes
hereunder. For this purpose, such Covenant Defeasance means that, with respect to the Outstanding Notes, the Company and the Subsidiary Guarantors may omit to comply with and shall have no liability in respect of any term, condition or limitation
set forth in any such covenant or provision, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or provision or by reason of any reference in any such covenant or provision to any other provision herein
or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Section 601, but, except as specified above, the remainder of this Indenture and such Outstanding Notes shall be unaffected
thereby. 
 Section 1204. Conditions to Defeasance or Covenant Defeasance. The following shall be the conditions to application
of either Section 1202 or Section 1203 to the Outstanding Notes: 
 (1) The Company shall have
irrevocably deposited or caused to be deposited with the Trustee, in trust, money or U.S. Government Obligations, or a combination thereof, in amounts as will be sufficient (without reinvestment), to pay and discharge the principal of, and premium,
if any, and interest on the Defeased Notes to the Stated Maturity or relevant Redemption Date in accordance with the terms of this Indenture and the Notes (provided that if such redemption shall be pursuant to Section 6(d) of the
applicable Notes Supplemental Indenture, (x) the amount of money or U.S. Government Obligations or a combination thereof that the Company must irrevocably deposit or cause to be deposited shall be determined using an assumed Applicable
Premium calculated as of the date of such deposit, as calculated by the Company in good faith and (y) the Company must irrevocably deposit or cause to be deposited additional money in trust on the Redemption Date, as required by
Section 1006, as necessary to pay the Applicable Premium as determined on such date); 
 (2) No Default or Event
of Default shall have occurred and be continuing on the date of such deposit; 

  
 129 








 (3) Such deposit shall not result in a breach or violation of, or constitute a
Default or Event of Default under, this Indenture or any other material agreement or instrument to which the Company is a party or by which it is bound; 

(4) In the case of an election under Section 1202, the Company shall have delivered to the Trustee an Opinion of
Counsel from Debevoise & Plimpton LLP or other counsel in the United States to the effect that (x) the Company has received from, or there has been published by, the Internal Revenue Service a ruling or (y) since the
Issue Date, there has been a change in the applicable Federal income tax law, in either case to the effect that, and based thereon such opinion shall confirm to the effect that, the Holders of the Outstanding Notes will not recognize income, gain or
loss for Federal income tax purposes as a result of such Defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Defeasance had not occurred;
provided that such Opinion of Counsel need not be delivered if all Notes theretofore authenticated and delivered (other than (i) Notes that have been destroyed, lost or stolen and that have been replaced or paid as provided in
Section 306, and (ii) Notes for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust, as provided in
Section 403) not theretofore delivered to the Trustee for cancellation have become due and payable, will become due and payable at their Stated Maturity within one year, or have been called for redemption or are to be called for
redemption within one year under arrangements reasonably satisfactory to the Trustee in the name, and at the expense, of the Company; 

(5) In the case of an election under Section 1203, the Company shall have delivered to the Trustee an Opinion of
Counsel from Debevoise & Plimpton LLP or other counsel in the United States to the effect that the Holders of the Outstanding Notes will not recognize income, gain or loss for Federal income tax purposes as a result of such Covenant
Defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred; and 

(6) The Company shall have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel from
Debevoise & Plimpton LLP or other counsel in the United States, each to the effect that all conditions precedent provided for in this Section 1204 relating to either the Defeasance under Section 1202 or the Covenant
Defeasance under Section 1203, as the case may be, have been complied with. In rendering such Opinion of Counsel, counsel may rely on an Officer’s Certificate as to compliance with the foregoing clauses (1), (2) and
(3) of this Section 1204 or as to any matters of fact. 

  
 130 








 Section 1205. Deposited Money and U.S. Government Obligations to Be Held in Trust; Other
Miscellaneous Provisions. Subject to the provisions of the last paragraph of Section 403, all money and U.S. Government Obligations (including the proceeds thereof) deposited with the Trustee (or such other Person that would qualify
to act as successor trustee under Article VII, collectively and solely for purposes of this Section 1205, the “Trustee”) pursuant to Section 1204 in respect of the Defeased 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 as the Trustee may determine, to the Holders of such Notes of all sums due and to
become due thereon in respect of principal, premium, if any, and interest, but such money need not be segregated from other funds except to the extent required by law. 

The Company shall pay and indemnify the Trustee and its agents and hold them harmless against any tax, fee or other charge imposed on or
assessed against the U.S. Government Obligations deposited pursuant to Section 1204, or the principal, premium, if any, and interest received in respect thereof, other than any such tax, fee or other charge that by law is for the account
of the Holders of the Defeased Notes. 
 Anything in this Article XII to the contrary notwithstanding, the Trustee shall deliver
to the Company from time to time, upon Company Request, any money or U.S. Government Obligations held by it as provided in Section 1204 that, in the opinion of a nationally recognized accounting or investment banking firm expressed in a
written certification thereof to the Trustee, are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Defeasance or Covenant Defeasance. Subject to Article VII, the Trustee shall not incur
any liability to any Person by relying on such opinion. 
 Section 1206. Reinstatement. If the Trustee or Paying Agent is unable
to apply any money or U.S. Government Obligations in accordance with Section 1202 or 1203, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise
prohibiting such application, then the obligations of the Company and each of the Subsidiary Guarantors under this Indenture, the Notes and the Subsidiary Guarantees shall be revived and reinstated as though no deposit had occurred pursuant to
Section 1202 or 1203, as the case may be, until such time as the Trustee or Paying Agent is permitted to apply all such money and U.S. Government Obligations in accordance with Section 1202 or 1203, as the case
may be; provided, however, that if the Company or any Subsidiary Guarantor makes any payment of principal, premium, if any, or interest on any Note following the reinstatement of its obligations, the Company or Subsidiary Guarantor, as
the case may be, shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money and U.S. Government Obligations held by the Trustee or Paying Agent. 

Section 1207. Repayment to the Company. The Trustee shall pay to the Company upon Company Request any money held by it for the
payment of principal or interest that remains unclaimed for two years after the Stated Maturity or the Redemption Date, as the 

  
 131 








 
case may be. After payment to the Company, Holders entitled to money must look to the Company for payment as general creditors unless an applicable abandoned property law designates another
Person and all liability of the Trustee or Paying Agent with respect to such money shall thereupon cease. 
 ARTICLE XIII 

SUBSIDIARY GUARANTEES 

Section 1301. Guarantees Generally. 

(a) Guarantee of Each Subsidiary Guarantor. From and after the Merger Date, each Subsidiary Guarantor from time to time party hereto, as
primary obligor and not merely as surety, hereby jointly and severally, irrevocably and fully and unconditionally Guarantees, on an unsecured senior basis, the punctual payment when due, whether at Stated Maturity, by acceleration or otherwise, of
all monetary obligations of the Company under this Indenture and the Notes, whether for principal of or interest on the Notes, expenses, indemnification or otherwise (all such obligations guaranteed by such Subsidiary Guarantors being herein called
the “Subsidiary Guaranteed Obligations”). 
 The obligations of each Subsidiary Guarantor will be limited to the maximum
amount as will, after giving effect to all other contingent and fixed liabilities of such Subsidiary Guarantor (including but not limited to any Guarantee by it of any Credit Facility Indebtedness) 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, result in the
obligations of such Subsidiary Guarantor under the Subsidiary Guarantee not constituting a fraudulent conveyance or fraudulent transfer under applicable law, or being void or unenforceable under any law relating to insolvency of debtors. 

(b) Further Agreements of Each Subsidiary Guarantor. (i) Each Subsidiary Guarantor hereby agrees that (to the fullest extent
permitted by law) its obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of this Indenture, the Notes or the obligations of the Company or any other Subsidiary Guarantor to the Holders or the
Trustee hereunder or thereunder, the absence of any action to enforce the same, any waiver or consent by any Holder 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, whether or not a notation concerning its Subsidiary Guarantee is made on any particular Note, or any other circumstance that might otherwise constitute a legal or equitable discharge or defense of a
Subsidiary Guarantor. 
 (ii) Each Subsidiary Guarantor hereby waives (to the fullest extent permitted by law) the benefit of diligence,
presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first 

  
 132 








 
against the Company, protest, notice and all demands whatsoever and covenants that (except as otherwise provided in Section 1303) its Subsidiary Guarantee will not be discharged
except by complete performance of the obligations contained in the Notes, this Indenture and this Subsidiary Guarantee. Such Subsidiary Guarantee is a guarantee of payment and not of collection. Each Subsidiary Guarantor further agrees (to the
fullest extent permitted by law) that, as between it, on the one hand, and the Holders of Notes and the Trustee, on the other hand, subject to this Article XIII, (1) the maturity of the obligations guaranteed by its
Subsidiary Guarantee may be accelerated as and to the extent provided in Article VI for the purposes of such Subsidiary Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the
obligations guaranteed by such Subsidiary Guarantee, and (2) in the event of any acceleration of such obligations as provided in Article VI, such obligations (whether or not due and payable) shall forthwith become due and
payable by such Subsidiary Guarantor in accordance with the terms of this Section 1301 for the purpose of such Subsidiary Guarantee. Neither the Trustee nor any other Person shall have any obligation to enforce or exhaust any rights or
remedies or to take any other steps under any security for the Subsidiary Guaranteed Obligations or against the Company or any other Person or any property of the Company or any other Person before the Trustee is entitled to demand payment and
performance by any or all Subsidiary Guarantors of their obligations under their respective Subsidiary Guarantees or under this Indenture. 

(iii) Until terminated in accordance with Section 1303, 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 such 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. 
 (c) Each Subsidiary Guarantor that makes a payment or distribution under its Subsidiary
Guarantee shall have the right to seek contribution from the Company or any non-paying Subsidiary Guarantor that has also Guaranteed the relevant Subsidiary Guaranteed Obligations in respect of which such payment or distribution is made, so long as
the exercise of such right does not impair the rights of the Holders under the Subsidiary Guarantees. 
 (d) Each Subsidiary Guarantor
acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated by this Indenture and that its Subsidiary Guarantee, and the waiver set forth in Section 1305, are knowingly made in
contemplation of such benefits. 

  
 133 








 (e) Each Subsidiary Guarantor, pursuant to its Subsidiary Guarantee, also hereby agrees to pay
any and all reasonable out-of-pocket expenses (including reasonable counsel fees and expenses) incurred by the Trustee or the Holders in enforcing any rights under its Subsidiary Guarantee. 

Section 1302. Continuing Guarantees. (a) Each Subsidiary Guarantee shall be a continuing Guarantee and shall
(i) subject to Section 1303, remain in full force and effect until payment in full of the principal amount of all Outstanding Notes (whether by payment at maturity, purchase, redemption, defeasance, retirement or other
acquisition) and all other Subsidiary Guaranteed Obligations then due and owing, (ii) be binding upon such Subsidiary Guarantor and (iii) inure to the benefit of and be enforceable by the Trustee, the Holders and their
permitted successors, transferees and assigns. 
 (b) The obligations of each Subsidiary Guarantor hereunder shall continue to be effective
or shall be reinstated, as the case may be, if at any time any payment which would otherwise have reduced or terminated the obligations of any Subsidiary Guarantor hereunder and under its Subsidiary Guarantee (whether such payment shall have been
made by or on behalf of the Company, or by or on behalf of a Subsidiary Guarantor) is rescinded or reclaimed from any of the Holders upon the insolvency, bankruptcy, liquidation or reorganization of the Company, or any Subsidiary Guarantor or
otherwise, all as though such payment had not been made. 
 Section 1303. Release of Subsidiary Guarantees. Notwithstanding the
provisions of Section 1302, Subsidiary Guarantees will be subject to termination and discharge under the circumstances described in this Section 1303. Any Subsidiary Guarantor will automatically and unconditionally be
released from all obligations under its Subsidiary Guarantee, and such Subsidiary Guarantee shall thereupon terminate and be discharged and of no further force or effect, (i) concurrently with any direct or indirect sale or disposition
(by merger or otherwise) of any Subsidiary Guarantor or any interest therein, or any other transaction, in accordance with the terms of this Indenture (including Section 411 and Section 501), following which such Subsidiary
Guarantor is no longer a Restricted Subsidiary of the Company, (ii) at any time that such Subsidiary Guarantor is (or, substantially concurrently with the release of the Subsidiary Guarantee of such Subsidiary Guarantor or if as a result
of the release of the Subsidiary Guarantee of such Subsidiary Guarantor, will be) released from all of its obligations under its Guarantee of payment by the Company and all other Subsidiary Guarantors of any Indebtedness of the Company and such
other Subsidiary Guarantors under the Senior Credit Facilities or any Capital Market Indebtedness, including by reason of ceasing to be a borrower under the Senior ABL Facility on a joint and several basis with the Company and (in the case of such
Capital Market Indebtedness) when initially granted resulted in such Subsidiary’s obligation to Guarantee the Notes pursuant to Section 414 (it being understood that a release subject to 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 

  
 134 








 
Subsidiary Guarantee pursuant to Section 414), (iii) upon the merger or consolidation of any Subsidiary Guarantor with and into the Company or another Subsidiary Guarantor
that is the surviving Person in such merger or consolidation, or upon the liquidation of such Subsidiary Guarantor following the transfer of all of its assets to the Company or another Subsidiary Guarantor, (iv) concurrently with any
Subsidiary Guarantor becoming an Unrestricted Subsidiary, (v) during the Suspension Period, upon the merger or consolidation of any Subsidiary Guarantor with and into another Subsidiary that is not a Subsidiary Guarantor with such other
Subsidiary being the surviving Person in such merger or consolidation, or upon liquidation of such Subsidiary Guarantor following the transfer of all of its assets to a Subsidiary that is not a Subsidiary Guarantor (it being understood that on a
Reversion Date, such Subsidiary Guarantee shall also be reinstated to the extent that such Subsidiary would then be required to provide a Subsidiary Guarantee pursuant to Section 414), (vi) upon Defeasance or Covenant
Defeasance of the Company’s obligations, or satisfaction and discharge of this Indenture pursuant to Section 1101, or (vii) subject to Section 1302(b), upon payment in full of the aggregate principal amount
of all Notes then Outstanding and all other Subsidiary Guaranteed Obligations then due and owing. In addition, the Company will have the right, upon 10 days’ notice to the Trustee (or such shorter period as agreed to by the Trustee in its
sole discretion), to cause any Subsidiary Guarantor that has not guaranteed payment by the Company or another Subsidiary Guarantor of any Indebtedness of the Company or such other Subsidiary Guarantor under the Senior Credit Facilities or any
Capital Market Indebtedness to be unconditionally released from all obligations under its Subsidiary Guarantee, and such Subsidiary Guarantee shall thereupon terminate and be discharged and of no further force or effect. 

Upon any such occurrence specified in this Section 1303, the Trustee shall, at the Company’s expense, execute any documents reasonably
requested by the Company in order to evidence such release, discharge and termination in respect of the applicable Subsidiary Guarantee. 

Section 1304. [Reserved]. 

Section 1305. Waiver of Subrogation. Each Subsidiary Guarantor hereby irrevocably waives any claim or other rights that it may now
or hereafter acquire against the Company that arise from the existence, payment, performance or enforcement of the Company’s obligations under the Notes and this Indenture or such Subsidiary Guarantor’s obligations under its Subsidiary
Guarantee and this Indenture, including any right of subrogation, reimbursement, exoneration, indemnification, and any right to participate in any claim or remedy of any Holder of Notes against the Company, whether or not such claim, remedy or right
arises in equity, or under contract, statute or common law, until this Indenture is discharged and all of the Notes are discharged and paid in full. If any amount shall be paid to any Subsidiary Guarantor in violation of the preceding sentence and
the Notes shall not have been paid in full, such amount shall be deemed to have been paid to such Subsidiary Guarantor for the benefit of, and held in trust for the benefit of, the Holders of the Notes, and shall forthwith be paid to the Trustee for
the benefit of such Holders to be credited and applied upon the Notes, whether matured or unmatured, in accordance with the terms of this Indenture. 

  
 135 








 Section 1306. Notation Not Required. Neither the Company nor any Subsidiary Guarantor
shall be required to make a notation on the Notes to reflect any Subsidiary Guarantee or any release, termination or discharge thereof.

20[    ] of the Company (herein called the “Notes”), issued under an Indenture, dated as of December 1, 2016 (the “Indenture,” which term shall have the meaning assigned to it in such
instrument), among the Company, as issuer, the Subsidiary Guarantors from time to time parties thereto, and Wilmington Trust, National Association, in its capacity as Trustee (herein called the “Trustee,” which term includes any
successor trustee under the Indenture), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, any other obligor upon this Note, the Trustee and
the Holders of the Notes and of the terms upon which the Notes are, and are to be, authenticated and delivered. The terms of the Notes include those stated in the Indenture. The Notes are subject to all such terms, and Holders are referred to the
Indenture for a statement of such terms. To the maximum extent permitted by law, in the case of any conflict between the provisions of this Note and the Indenture, the provisions of the Indenture shall control. Additional Notes may be issued from
time to time in one or more series under the Indenture and (except as provided in Section 902 of the Indenture) will vote as a class with the Notes and otherwise be treated as Notes for purposes of the Indenture. 

All terms used in this Note that are defined in the Indenture shall have the meanings assigned to them in the Indenture. 

This Note may hereafter be entitled to certain other senior Subsidiary Guarantees made for the benefit of the Holders. Reference is made to
Article XIII of the Indenture for terms relating to such Subsidiary Guarantees, including the release, termination and discharge thereof. Neither the Company nor any Subsidiary Guarantor shall be required to make any notation on this Note to
reflect any Subsidiary Guarantee or any such release, termination or discharge. 
 The Notes are redeemable, at the Company’s option,
in whole or in part, as provided in the Indenture and the [[            ] Supplemental Indenture, dated as of [            ],

The Indenture provides (as and to the extent set forth therein) that, upon the occurrence after the Issue Date of a Change of Control,
each Holder will have the right to require that the Company repurchase all or any part of such Holder’s Notes at a purchase price in cash equal to 101.0% of the principal amount thereof plus accrued and unpaid interest, if any, to the
date of such repurchase (subject to the right of Holders of record on the relevant Regular Record Date to receive interest due on the relevant Interest Payment Date falling prior to or on the purchase date); provided, however, that the
Company shall not be obligated to repurchase Notes in the event it has exercised its right to redeem all the Notes as provided in the Indenture.

thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Notes to be effected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of at least a majority
in principal amount of the Notes at the time Outstanding to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Notes at the time Outstanding, on behalf of the Holders of all
Notes, to waive compliance by the Company and its Subsidiaries with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Note shall be conclusive
and binding upon such Holder and upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note.

 As provided in and subject to the provisions of the Indenture, the Holder of this Note shall not have the right to institute any
proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to
the Notes, the Holders of not less than 30.0% in principal amount of the Notes at the time Outstanding (which contain such Event of Default) shall have made written request to the Trustee to pursue such remedy in respect of such Event of Default as
Trustee and offered the Trustee security or indemnity satisfactory to it against any loss, liability or expense, and the Trustee shall not have received from the Holders of a majority in principal amount of Notes at the time Outstanding a direction
inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of security or indemnity. The foregoing shall not apply to any suit instituted by the Holder of this
Note for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein.

 In connection with our proposed sale of

1. We understand that any subsequent transfer of the Notes is subject to certain restrictions and conditions set forth in the Indenture dated

in compliance with, such restrictions and conditions and the Securities Act of 1933, as amended (the “Securities Act”). 

2. We understand that the Notes have not been registered under the Securities Act or any other applicable securities law, and that the Notes
may not be offered, sold or otherwise transferred except as permitted in the following sentence. We agree, on our own behalf and on behalf of any accounts for which we are acting as hereinafter stated, that if we should offer, sell, transfer,
pledge, hypothecate or otherwise dispose of any Notes within one year after the original issuance of the Notes, we will do so only (A) to the Company or a Subsidiary, (B) inside the United States to a “qualified
institutional buyer” in compliance with Rule 144A under the Securities Act, (C) inside the United States to an institutional “accredited investor” (as defined below) that, prior to such transfer, furnishes to you a signed
letter substantially in the form of this letter, (D) outside the United States to a foreign person in compliance with Rule 904 of Regulation S under the Securities Act, (E) pursuant to the exemption from registration provided
by Rule 144 under the Securities Act (if available), or (F) pursuant to an effective registration statement under the Securities Act, and we further agree to provide to any person purchasing any of the Notes from us a notice advising
such purchaser that resales of the Notes are restricted as stated herein and in the Indenture. 
 3. We understand that, on any proposed
transfer of any Notes prior to the later of the original issue date of the Notes and the last date the Notes were held by an affiliate of the Company pursuant to paragraphs 2(C), 2(D) and 2(E) above, we will be required to furnish to

you and the Company such certifications, legal opinions and other information as you and the Company may reasonably require to confirm that the proposed transfer complies with the foregoing
restrictions. We further understand that the Notes purchased by us will bear a legend to the foregoing effect. 
 4. We are an institutional
“accredited investor” (as defined in Rule 501(a)(1), (2), (3) or (7) under the Securities Act) and have such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of our
investment in the Notes, and we and any accounts for which we are acting are acquiring the Notes for investment purposes and not with a view to, or offer or sale in connection with, any distribution in violation of the Securities Act, and we are
each able to bear the economic risk of our or its investment. 
 5. We are acquiring the Notes purchased by us for our own account or for one
or more accounts (each of which is an institutional “accredited investor”) as to each of which we exercise sole investment discretion. 

You, the Company and counsel to the Company are entitled to rely upon this letter and are irrevocably authorized to produce this letter or a

and issue Additional Notes having the same terms and conditions as the [            ] Notes in all respects or in all respects except

equal to up to [            ]%31 of the original aggregate principal amount of the
Notes (including the principal amount of any Additional [            ] Notes, or any other Additional Notes of the same series as the
[            ] Notes), with funds in an equal aggregate amount (the “Redemption Amount”) not exceeding the aggregate proceeds of one or more Equity Offerings, at a

[            ] Notes, or any other Additional Notes of the same series as the [            ] Notes) must remain outstanding
immediately after each such redemption. 
 The Company may make such redemption upon notice sent to each Holder’s registered address in
accordance with Section 1005 of the Indenture, and, if applicable, the Company should notify the Trustee of such Redemption Date, and the principal amount of Notes to be redeemed, in accordance with Section 1003 of the Indenture (but in no
event more than 180 days after the completion of the related Equity Offering). The Company may provide in such notice that payment of the redemption price and performance of the Company’s obligations with respect to such redemption may be
performed by another Person. Any such notice may be given prior to the completion of the related Equity Offering, and any such redemption or notice may, at the Company’s discretion, be subject to the satisfaction of one or more conditions
precedent, including but not limited to the completion of the related Equity Offering.

payment of the Redemption Price and performance of the Company’s obligations with respect to such redemption may be performed by another Person. Any such redemption or notice may, at the
Company’s discretion, be subject to the satisfaction of one or more conditions precedent, including but not limited to the occurrence of a Change of Control. 

“Applicable Premium” means, with respect to an [            ]
Note at any Redemption Date, the greater of (i) 1.00% of the principal amount of such [            ] Note and (ii) the excess of (A) the present value at
such Redemption Date, calculated as of the date of the applicable redemption notice, of (1) the redemption price of such [            ] Note on
[[            ], 20[    ]]35 (such redemption price being that described in Section 6(a)), plus
(2) all required remaining scheduled interest payments due on such [            ] Note through such date (excluding accrued and unpaid interest to the Redemption Date), computed

Company or on behalf of the Company by such Person as the Company shall designate; provided that such calculation shall not be a duty or obligation of the Trustee. 

“Treasury Rate” means, with respect to a Redemption Date, the weekly average yield to maturity at the time of computation of
United States Treasury securities with a constant maturity (as compiled and published in the most recent Federal Reserve Statistical Release H.15(519) that has become publicly available at least two Business Days prior to the date of the applicable
redemption notice (or, if such Statistical Release is no longer published, any publicly available source of similar market data)) most nearly equal to the period from such Redemption Date to
[[            ], 20[    ]];36 provided, however, that if the period from the Redemption Date to such
date is not equal to the constant maturity of a United States Treasury security for which a weekly average yield is given, the Treasury Rate shall be obtained by linear interpolation (calculated to the nearest one-twelfth of a year) from the weekly
average yields of United States Treasury securities for which such yields are given, except that if the period from the Redemption Date to such date is less than one year, the weekly average yield on actually traded United States Treasury securities
adjusted to a constant maturity of one year shall be used. 
 (e) Notwithstanding clauses (a), (b), (c) and (d) of this
Section 6, in connection with any tender for the [            ] Notes, if Holders of not less than 90% in the aggregate principal amount of the outstanding

the [            ] Notes (including any Additional [            ] Notes and any Additional Notes of the same series as the
[            ] Notes) validly tendered and not withdrawn by such Holders, the Company will have the right, upon notice given not more than 30 days following such purchase pursuant to such
tender offer, to redeem all of the [            ] Notes that remain outstanding following such purchase at a price in

Date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant Interest Payment Date falling prior to or on the Redemption Date). 

(f) Any redemption of Notes pursuant to this Section 6 may be made upon notice sent electronically or, at the Company’s option,
mailed by first-class mail to each Holder’s registered address in accordance with Section 1005 of the Indenture. The Company may provide in any redemption notice that payment of the redemption price and the performance of the
Company’s obligations with respect to such redemption may be performed by another Person. 
 (g) Any redemption of Notes pursuant to
this Section 6 (including in connection with an Equity Offering) or notice thereof may, at the Company’s discretion, be subject to the satisfaction (or, waiver by the Company in its sole discretion) of one or more conditions
precedent, which may include consummation of any related Equity Offering or the occurrence of a Change of Control. If such redemption or notice is subject to satisfaction of one or more conditions precedent, such notice may state that, in the
Company’s discretion, the Redemption Date may be delayed until such time as any or all such conditions shall be satisfied (or waived by the Company in its sole discretion), or such redemption may not occur and such notice may be rescinded in
the event that any or all such conditions shall not have been (or, in the Company’s sole determination, may not be) satisfied (or waived by the Company in its sole discretion) by the Redemption Date, or by the Redemption Date so delayed.
