Execution and Authentication.


 


At least one Officer
must sign the Notes for each Issuer by manual or facsimile signature.


 


If an Officer whose
signature is on a Note no longer holds that office at the time a Note is authenticated, the Note will nevertheless be valid.


 


A Note will not be
valid until authenticated by the manual signature of the Trustee. The signature will be conclusive evidence that the Note has been
authenticated under this Indenture.


 


The Trustee will, upon
receipt of a written order of the Issuers signed by an Officer of each Issuer (an “Authentication Order”), authenticate
Notes for original issue that may be validly issued under this Indenture, including any Additional Notes. The aggregate principal
amount of Notes outstanding at any time may not exceed the aggregate principal amount of Notes authorized for issuance by the Issuers
pursuant to one or more Authentication Orders, except as provided in Section 2.07 hereof.


 


The Trustee may appoint
an authenticating agent acceptable to the Issuers to authenticate Notes. An authenticating agent may authenticate Notes whenever
the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent.
An authenticating agent has the same rights as an Agent to deal with Holders or an Affiliate of the Company.


 


Section 2.03        
Registrar and Paying Agent.


 


The Issuers will maintain
an office or agency where Notes may be presented for registration of transfer or for exchange (“Registrar”)
and an office or agency where Notes may be presented for payment (“Paying Agent”). The Registrar will keep a
register of the Notes and of their transfer and exchange. The Issuers may appoint one or more co-registrars and one or more additional
paying agents. The term “Registrar” includes any co-registrar and the term “Paying Agent” includes any
additional paying agent. The Issuers may change any Paying Agent or Registrar without notice to any Holder. The Issuers will notify
the Trustee in writing of the name and address of any Agent not a party to this Indenture. If the Issuers fail to appoint or maintain
another entity as Registrar or Paying Agent, the Trustee shall act as such. The Parent or any of the Parent’s Subsidiaries
may act as Paying Agent or Registrar.


 


The Issuers initially
appoint The Depository Trust Company (“DTC”) to act as Depositary with respect to the Global Notes.


 


The Issuers initially
appoint the Trustee to act as the Registrar and Paying Agent (at its offices indicated in the definition of Corporate Trust Office
of the Trustee in Section 1.01 hereof) and to act as Custodian with respect to the Global Notes.


 


Section 2.04        
Paying Agent to Hold Money in Trust.


 


The Issuers will require
each Paying Agent other than the Trustee to agree in writing that the Paying Agent will hold in trust for the benefit of Holders
or the Trustee all money held by the Paying Agent for the payment of principal of, premium on, if any, or interest on, the Notes,
and will notify the Trustee of any default by the Issuers in making any such payment. While any such default continues, the Trustee
may require a Paying Agent to pay all money held by it to the Trustee. The Issuers at any time may require a Paying Agent to pay
all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the Issuers or a Subsidiary)
will have no further liability for the money. If the Issuers or a Subsidiary acts as Paying Agent, it will segregate and hold in
a separate trust fund for the benefit of the Holders all money held by it as Paying Agent. Upon any bankruptcy or reorganization
proceedings relating to the Issuers, the Trustee will serve as Paying Agent for the Notes.

Section 2.05        
Holder Lists.


 


The Trustee will preserve
in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of all Holders.
If the Trustee is not the Registrar, the Issuers will furnish to the Trustee at least seven Business Days before each interest
payment date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee
may reasonably require of the names and addresses of the Holders of Notes.


 


Section 2.06        
Transfer and Exchange.


 


(a)         
Transfer and Exchange of Global Notes. A Global Note may not be transferred except as a whole by the Depositary to
a nominee of the Depositary, by a nominee of the Depositary to the Depositary or to another nominee of the Depositary, or by the
Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. All Global Notes will be exchanged
by the Issuers for Definitive Notes if:


 


(1)          
the Depositary (A) notifies the Issuers that it is unwilling or unable to continue to act as Depositary or has ceased
to be a clearing agency registered under the Exchange Act and, in either case, a successor Depositary is not appointed by the Issuers
within 90 days after the date of such notice from the Depositary;


 


(2)          
the Issuers, at their option but subject to the Depositary’s requirements, notify the Trustee in writing that
they elect to cause the issuance of the Definitive Notes; or


 


(3)          
there has occurred and is continuing an Event of Default, and the Depositary notifies the Trustee of its decision
to exchange such Global Note for Definitive Notes.


 


Upon the occurrence
of any of the preceding events in (1), (2) or (3) above, Definitive Notes shall be issued in such names as the Depositary shall
instruct the Trustee. Global Notes also may be exchanged or replaced, in whole or in part, as provided in Sections 2.07 and 2.10
hereof. Every Note authenticated and delivered in exchange for, or in lieu of, a Global Note or any portion thereof, pursuant to
this Section 2.06 or Section 2.07 or 2.10 hereof, shall be authenticated and delivered in the form of, and shall be, a Global Note.
A Global Note may not be exchanged for another Note other than as provided in this Section 2.06(a), however, beneficial interests
in a Global Note may be transferred and exchanged as provided in Section 2.06(b) or (c) hereof.


 


(b)          
Transfer and Exchange of Beneficial Interests in the Global Notes. The transfer and exchange of beneficial interests

Transfer of Beneficial Interests in the Same Global Note. Beneficial interests in any Restricted Global Note

the expiration of the Restricted Period, transfers of beneficial interests in the Regulation S Global Note may not be made to a
U.S. Person or for the account or benefit of a U.S. Person (other than an Initial Purchaser). Beneficial interests in any Unrestricted

Note. No written orders or instructions shall be required to be delivered to the Registrar to effect the transfers described in
this Section 2.06(b)(1).

Section 2.07           
Replacement Notes.


 


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


 


Every replacement Note
is an additional obligation of the Issuers and will be entitled to all of the benefits of this Indenture equally and proportionately
with all other Notes duly issued hereunder.


 


Section 2.08           
Outstanding Notes.


 


The Notes outstanding
at any time are all the Notes authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation,
those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described
in this Section 2.08 as not outstanding. Except as set forth in Section 2.09 hereof, a Note does not cease to be outstanding because
the Issuers or an Affiliate of the Issuers holds the Note, however, Notes held by the Parent or a Subsidiary of the Parent shall
not be deemed to be outstanding for purposes of Section 3.07(a) hereof.


 


If a Note is replaced
pursuant to Section 2.07 hereof, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced
Note is held by a protected purchaser.


 


If the principal amount
of any Note is considered paid under Section 4.01 hereof, it ceases to be outstanding and interest on it ceases to accrue.


 


If the Paying Agent
(other than the Issuers, a Subsidiary or an Affiliate of any thereof) holds, by 10:00 a.m. Eastern Time on a redemption date or
other maturity date, money sufficient to pay Notes payable on that date, then on and after that date such Notes will be deemed
to be no longer outstanding and will cease to accrue interest.


 


Section 2.09        
Treasury Notes.


 


In determining whether
the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Issuers
or any Guarantor, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control
with the Issuers or any Guarantor, will be considered as though not outstanding, except that for the purposes of determining whether
the Trustee will be protected in relying on any such direction, waiver or consent, only Notes that a Responsible Officer of the
Trustee actually knows are so owned will be so disregarded.


 


Section 2.10        
Temporary Notes.


 


Until certificates
representing Notes are ready for delivery, the Issuers may prepare and the Trustee, upon receipt of an Authentication Order, will
authenticate temporary Notes. Temporary Notes will be substantially in the form of certificated Notes but may have variations that
the Issuers consider appropriate for temporary Notes and as may be reasonably acceptable to the Trustee. Without unreasonable delay,
the Issuers will prepare and the Trustee will authenticate definitive Notes in exchange for temporary Notes.


 



    	 	38	 



     


    

 





Holders of temporary
Notes will be entitled to all of the benefits of this Indenture.


 


Section 2.11        
Cancellation.


 


The Issuers at any
time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent will forward to the Trustee any Notes surrendered
to them for registration of transfer, exchange or payment. The Trustee and no one else will cancel all Notes surrendered for registration
of transfer, exchange, payment, replacement or cancellation and will dispose of canceled Notes in accordance with the Trustee’s
customary procedures. Certification of the destruction of all canceled Notes will be delivered to the Issuers upon written request.
The Issuers may not issue new Notes to replace Notes that it has paid or that have been delivered to the Trustee for cancellation.


 


Section 2.12        
Defaulted Interest.


 


If the Issuers default
in a payment of interest on the Notes, they will pay the defaulted interest in any lawful manner plus, to the extent lawful, interest
payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, in each case at the rate
provided in the Notes and in Section 4.01 hereof. The Issuers will notify the Trustee in writing of the amount of defaulted interest
proposed to be paid on each Note and the date of the proposed payment. The Issuers will fix or cause to be fixed each such special
record date and payment date; provided that no such special record date may be less than 10 days prior to the related payment
date for such defaulted interest. At least 15 days before the special record date, the Issuers (or, upon the written request of
the Issuers, the Trustee in the name and at the expense of the Issuers) will send to Holders a notice that states the special record
date, the related payment date and the amount of such interest to be paid. The Trustee will not have any duty to determine whether
any defaulted interest is payable or the amount thereof.


 


ARTICLE 3

REDEMPTION AND PREPAYMENT


 


Section 3.01        
Notices to Trustee.


 


If the Issuers elect
to redeem Notes pursuant to the optional redemption provisions of Section 3.07 hereof, they must furnish to the Trustee, at least
five Business Days prior to the giving of notice of redemption pursuant to Section 3.03 hereof, a notice in writing setting forth:


 


(1)           
the clause of this Indenture pursuant to which the redemption shall occur and the conditions precedent, if any, to
the redemption;


 


(2)           
the redemption date;


 


(3)          
the principal amount of Notes to be redeemed; and


 


(4)          
the redemption price (if then determined and otherwise the method of determination).


 



    	 	39	 



     


    





 


Section 3.02        Selection
of Notes to Be Redeemed.


 


If less than all of
the Notes are to be redeemed at any time, the Trustee will select Notes for redemption on a pro rata basis (or, in the case of
Notes issued in global form pursuant to Article 2 hereof, by such method as DTC may require), unless otherwise required by law.


 


In the event of partial
redemption, the particular Notes to be redeemed will be selected, unless otherwise provided herein, not less than 30 nor more than
60 days prior to the redemption date by the Trustee from the outstanding Notes not previously called for redemption.


 


The Trustee will promptly
notify the Issuers 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. Notes and portions of Notes selected will be in amounts of $2,000 or whole multiples
of $1,000 in excess thereof; except that if all of the Notes of a Holder are to be redeemed, the entire outstanding amount of Notes
held by such Holder shall be redeemed. Except as provided in the preceding sentence, provisions of this Indenture that apply to
Notes called for redemption also apply to portions of Notes called for redemption.


 


Section 3.03        Notice
of Redemption.


 


At least 30 days but
not more than 60 days before a redemption date, the Issuers will send a notice of redemption to each Holder whose Notes are to
be redeemed, except that redemption notices may be sent more than 60 days prior to a redemption date if the notice is issued in
connection with a defeasance of the Notes or a satisfaction and discharge of this Indenture pursuant to Article 8 or 11 hereof,
respectively.


 


The notice will identify
the Notes, including CUSIP numbers, to be redeemed and will state:


 


(1)          the
redemption date;


 


(2)          the redemption price (if then determined and otherwise the method of determination);


 


(3)          if any Note is being redeemed in part, the portion of the principal amount of such Note to be redeemed and that,
after the redemption date upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion
will be issued in the name of the Holder thereof upon cancellation of the original Note;


 


(4)         
the name and address of the Paying Agent;


 


(5)          that Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price;


 


(6)         
that, unless the Issuers default in making such redemption payment or the redemption is subject to conditions precedent
that are not satisfied prior to the redemption date, interest on Notes or portions thereof called for redemption ceases to accrue
on and after the redemption date;


 


(7)          the paragraph of the Notes and/or Section of this Indenture pursuant to which the Notes called for redemption are
being redeemed and the conditions precedent, if any, to the redemption; and


 






    	 	40	 



     


    

 


(8)          that no representation is made as to the correctness or accuracy of the CUSIP number listed in such notice or printed
on the Notes.


 


At the Issuers’
written request, the Trustee will give the notice of redemption in the Issuers’ names and at the Issuers’ expense;
provided, however, that the notice delivered to the Trustee pursuant to Section 3.01 hereof requests that the Trustee give
such notice of redemption and sets forth the information to be stated in such notice as provided in the preceding paragraph.


 


Section 3.04        Effect
of Notice of Redemption.


 


Once notice of redemption
is given in accordance with Section 3.03 hereof, Notes called for redemption without any condition precedent become irrevocably
due and payable on the redemption date at the redemption price. Any redemption or notice of redemption may, at the Company’s
discretion, be subject to one or more conditions precedent. Any Note called for redemption subject to any conditions precedent,
which conditions have become satisfied prior to the redemption date, shall become irrevocably due and payable on the redemption
date at the redemption price.


 


Section 3.05        Deposit
of Redemption Price.


 


No later than 10:00
a.m. Eastern Time on the redemption date, the Issuers will deposit with the Trustee or with the Paying Agent money sufficient to
pay the redemption price of, and accrued interest on, all Notes to be redeemed on that date. The Trustee or the Paying Agent will
promptly return to the Issuers any money deposited with the Trustee or the Paying Agent by the Issuers in excess of the amounts
necessary to pay the redemption price of, and accrued interest on, all Notes to be redeemed.


 


If the Issuers comply
with the provisions of the preceding paragraph, on and after the redemption date, interest will cease to accrue on the Notes or
the portions of Notes called for redemption. If a Note is redeemed on or after an interest record date but on or prior to the related
interest payment date, then any accrued and unpaid interest shall be paid to the Person in whose name such Note was registered
at the close of business on such record date. If any Note called for redemption is not so paid upon surrender for redemption because
of the failure of the Issuers to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the
redemption date until such principal is paid, and to the extent lawful on any interest not paid on such unpaid principal, in each
case at the rate provided in the Notes and in Section 4.01 hereof.


 


Section 3.06        Notes
Redeemed in Part.


 


Upon surrender of a
Note that is redeemed in part, the Issuers will issue and, upon receipt of an Authentication Order, the Trustee will authenticate
for the Holder at the expense of the Issuers a new Note equal in principal amount to the unredeemed portion of the Note surrendered.

(c)          Except pursuant to Section 3.07(a), (b) or (e), the Notes will not be redeemable at the Issuers’ option prior to April
1, 2023.


 


(d)         On and after April 1, 2023, the Issuers may on any one or more occasions redeem all or a part of the Notes, at the redemption
prices (expressed as percentages of principal amount) set forth below, plus accrued and unpaid interest, if any, on the Notes redeemed

on April 1 of the years indicated below:


 


	Year	 	Percentage

	2025	 	 	101.042	%
	2026 and thereafter	 	 	100.000	%



 


Unless the Issuers default
in the payment of the redemption price, interest will cease to accrue on the Notes or portions thereof called for redemption on
the applicable redemption date.


 


(e)          The
Issuers may redeem all (but not a portion of) the Notes when permitted by, and pursuant to the conditions in, Section 4.15(d)
hereof.


 


(f)          Any

Section 3.09        Offer
to Purchase by Application of Excess Proceeds.


 


In the event that,
pursuant to Section 4.10 hereof, the Company is required to commence an offer to all Holders to purchase Notes (an “Asset
Sale Offer”), it will follow the procedures specified below.


 


The Asset Sale Offer
shall be made to all Holders and all holders of other Indebtedness that is pari passu with the Notes containing provisions
similar to those set forth in this Indenture with respect to offers to purchase, prepay or redeem with the proceeds of sales of
assets. The Asset Sale Offer will remain open for a period of at least 20 Business Days following its commencement and not more
than 30 Business Days, except to the extent that a longer period is required by applicable law (the “Offer Period”).
No later than three Business Days after the termination of the Offer Period (the “Purchase Date”), the Company
will apply all Excess Proceeds (the “Offer Amount”) to the purchase of Notes and such other pari passu
Indebtedness (on a pro rata basis based on the principal amount of Notes and such other pari passu Indebtedness surrendered,
if applicable, except that any Notes represented by a Note in global form will be selected by such basis as DTC may require) or,
if less than the Offer Amount has been tendered, all Notes and other Indebtedness tendered in response to the Asset Sale Offer.
Payment for any Notes so purchased will be made in the same manner as interest payments are made.


 


If the Purchase Date
is on or after an interest record date and on or before the related interest payment date, any accrued and unpaid interest will
be paid to the Person in whose name a Note is registered at the close of business on such record date, and no additional interest
will be payable to Holders who tender Notes pursuant to the Asset Sale Offer.


 


Upon the commencement
of an Asset Sale Offer, the Company will send a notice to each of the Holders, with a copy to the Trustee. The notice will contain
all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Asset Sale Offer. The notice, which
will govern the terms of the Asset Sale Offer, will state:


 


(1)          that the Asset Sale Offer is being made pursuant to this Section 3.09 and Section 4.10 hereof and the length of time
the Asset Sale Offer will remain open;


 


(2)          the Offer Amount, the purchase price and the expiration date of the Asset Sale Offer;


 


(3)          that any Note not tendered or accepted for payment will continue to accrue interest;


 


(4)          that, unless the Company defaults in making such payment, any Note accepted for payment pursuant to the Asset Sale
Offer will cease to accrue interest after the Purchase Date;


 


(5)          that
Holders electing to have a Note purchased pursuant to an Asset Sale Offer may elect to have Notes purchased in denominations of
$2,000 or an integral multiple of $1,000 in excess thereof;


 


(6)          that
Holders electing to have Notes purchased pursuant to any Asset Sale Offer will be required to surrender the Note, with the form
entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer by book-entry transfer,
to the Company, a depositary, if appointed by the Company, or a Paying Agent at the address specified in the notice at least three
days before the Purchase Date;


 


(7)          that
Holders will be entitled to withdraw their election if the Company, the Depositary or the Paying Agent, as the case may be, receives,
not later than the expiration of the Offer Period, a telegram, electronic image scan, facsimile transmission or letter setting
forth the name of the Holder, the principal amount of the Note the Holder delivered for purchase and a statement that such Holder
is withdrawing his election to have such Note purchased;


 






    	 	43	 



     


    

 


(8)          that,
if the aggregate principal amount of Notes surrendered by Holders thereof exceeds the Offer Amount allocated to the purchase of
Notes in the Asset Sale Offer, the Trustee will select the Notes to be purchased on a pro rata basis (except that any Notes
represented by a Global Note shall be selected by such method as DTC may require) based on the principal amount of Notes surrendered
(with such adjustments as may be deemed appropriate by the Company so that only Notes in denominations of $2,000, or an integral
multiple of $1,000 in excess thereof, will be purchased); and


 


(9)          that Holders whose Notes were purchased only in part will be issued new Notes equal in principal amount to the unpurchased
portion of the Notes surrendered (or transferred by book-entry transfer).


 


On or before the Purchase
Date, the Company will, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Notes
or portions thereof tendered pursuant to the Asset Sale Offer and required to be purchased pursuant to this Section 3.09 and Section 4.10,
or if Notes in an aggregate principal amount less than the Offer Amount allocated to the purchase of Notes in an Asset Sale Offer
have been tendered, all Notes tendered, and will deliver or cause to be delivered to the Trustee the Notes properly accepted together
with an Officers’ Certificate stating that such Notes or portions thereof were accepted for payment by the Company in accordance
with the terms of this Section 3.09. The Company, the depositary for the Asset Sale Offer or the Paying Agent, as the case may
be, will promptly (but in any case not later than five days after the Purchase Date) mail or deliver to each tendering Holder an
amount equal to the purchase price of the Notes tendered by such Holder and accepted by the Company for purchase, and the Issuers
will promptly issue a new Note, and the Trustee, upon receipt of an Authentication Order, will authenticate and mail or deliver
(or cause to be transferred by book entry) such new Note to such Holder, in a principal amount equal to any unpurchased portion
of the Note surrendered. Any Note not so accepted shall be promptly mailed or delivered by the Company to the Holder thereof. The
Company will publicly announce the results of the Asset Sale Offer on the Purchase Date.

Section 4.01        Payment
of Notes.


 


The Issuers will pay
or cause to be paid the principal of, premium on, if any, and interest on the Notes on the dates and in the manner provided in
the Notes. Principal, premium, if any, and interest will be considered paid on the date due if the Paying Agent, if other than
the Parent or a Subsidiary of the Parent, holds as of 10:00 a.m. Eastern Time on the due date money deposited by the Issuers in
immediately available funds and designated for and sufficient to pay all principal, premium, if any, and interest, if any, then
due.


 


The Issuers will pay
interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal at a rate that is 1%
higher than the then applicable interest rate on the Notes to the extent lawful; they will pay interest (including post-petition
interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace
period), at the same rate to the extent lawful.

Section 4.02         Maintenance
of Office or Agency.


 


The Issuers will maintain
in the City and State of New York, an office or agency (which may be an office of the Trustee or an affiliate of the Trustee or
Registrar) where Notes may be surrendered for payment, and they will maintain in the continental United States an office or agency
where Notes may be surrendered for registration of transfer or for exchange and where notices and demands to or upon the Issuers
in respect of the Notes and this Indenture may be served. The Issuers will give prompt written notice to the Trustee of any change
in the location of such office or agency. If at any time the Issuers fail to maintain any such required office or agency or fail
to furnish the Trustee with notice of a change in the address thereof, such presentations, surrenders, notices and demands may
be made or served at the Corporate Trust Office of the Trustee.


 


The Issuers may also
from time to time designate one or more other offices or agencies where the Notes may be presented or surrendered for any or all
such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission
will in any manner relieve the Issuers of their obligation to maintain an office or agency in the City and State of New York for
purposes of making payments on the Notes. The Issuers will give prompt written notice to the Trustee of any such designation or
rescission and of any change in the location of any such other office or agency.


 


Section 4.03         Reports.


 


(a)          Whether or not required by the Commission, so long as any Notes are outstanding, the Parent will file with the Commission
for public availability within the time periods specified in the Commission’s rules and regulations (unless the Commission
will not accept such a filing), and the Parent will, within five Business Days after filing, or attempting to file, the same with
the Commission, (a) furnish to the Trustee and, upon its prior request, to any of the Holders or Beneficial Owners of Notes and
(b) post on its website or otherwise make available to prospective purchasers of the Notes:


 


(1)          all
quarterly and annual financial and other information with respect to the Parent and its Subsidiaries that would be required to
be contained in a filing with the Commission on Forms 10-Q and 10-K if the Parent were required to file such Forms, including
a “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and, with respect
to the annual information only, a report on the annual financial statements by the Parent’s independent registered public
accountants; and


 


(2)          all
current reports that would be required to be filed with the Commission on Form 8-K if the Parent were required to file such reports.


 


All such reports will
be prepared in all material respects in accordance with all of the rules and regulations applicable to such reports, including
Section 3-10 of Regulation S-X, if the Parent is not then subject to the reporting requirements of Section 13 or 15(d) of the Exchange
Act. The availability of the foregoing information or reports on the SEC’s website will be deemed to satisfy the foregoing
delivery requirements.


 


If the Parent has designated
any of its Subsidiaries as Unrestricted Subsidiaries, and such Unrestricted Subsidiaries, individually or taken together, would
constitute a Significant Subsidiary, then the quarterly and annual financial information required by the preceding paragraph will
include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes thereto, and in
Management’s Discussion and Analysis of Financial Condition and Results of Operations, of the financial condition and results
of operations of the Parent and its Restricted Subsidiaries excluding the Unrestricted Subsidiaries.

(b)         Any
and all Defaults or Events of Default arising from a failure to furnish or file in a timely manner a report or certification required
by this Section 4.03 shall be deemed cured (and the Parent shall be deemed to be in compliance with this Section 4.03) upon furnishing
or filing such report or certification as contemplated by this Section 4.03 (but without regard to the date on which such report
or certification is so furnished or filed); provided that such cure shall not otherwise affect the rights of the Holders
under Article 6 hereof if the principal, premium, if any, and interest have been accelerated in accordance with the terms of this
Indenture and such acceleration has not been rescinded or cancelled prior to such cure.


 


(c)         For so long as any Notes remain outstanding, if at any time they are not required to file with the SEC the reports required
by paragraph (a) of this Section 4.03, the Issuers and the Guarantors will furnish to the Holders and Beneficial Owners of the
Notes and to securities analysts and prospective investors, upon their request, the information required to be delivered pursuant
to Rule 144A(d)(4) under the Securities Act.


 


(d)         Delivery
of such reports, information and documents to the Trustee is for informational purposes only, and the Trustee’s receipt
thereof shall not constitute actual or constructive knowledge or notice of any information contained therein or determinable from
information contained therein, including each of the Issuers’ and the Guarantors’ compliance with any of its covenants
under this Indenture (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates). The Trustee will
not be obligated to monitor or confirm, on a continuing basis or otherwise, the Issuers’ compliance with this Section 4.03
or to determine whether such reports, information or documents have been posted on any website or filed with the Commission.


 


Section 4.04         Compliance
Certificate.


 


(a)          The
Parent, Issuers and each other Guarantor shall deliver to the Trustee, within 90 days after the end of each fiscal year, beginning
with the fiscal year ending December 31, 2019, an Officers’ Certificate stating that a review of the activities of the Parent
and its Subsidiaries during the preceding fiscal year has been made under the supervision of the signing Officers with a view
to determining whether the Parent and the Issuers have kept, observed, performed and fulfilled their obligations under this Indenture,
and further stating, as to each such Officer signing such certificate, that to the best of his or her knowledge the Parent and
the Issuers have kept, observed, performed and fulfilled each and every covenant contained in this Indenture and are not in default
in the performance or observance of any of the terms, provisions and conditions of this Indenture (or, if a Default or Event of
Default has occurred, describing all such Defaults or Events of Default of which he or she may have knowledge and what action
the Parent and the Issuers are taking or propose to take with respect thereto).


 


(b)         So long as any of the Notes are outstanding, the Issuers will deliver to the Trustee, within ten Business Days upon any
Officer of the Parent or the Issuers becoming aware of any Default or Event of Default, a written statement specifying such Default
or Event of Default and what action the Issuers are taking or propose to take with respect thereto.


 


Section 4.05         Taxes.


 


The Parent will pay,
and will cause each of its Subsidiaries to pay, prior to delinquency, all material taxes, assessments, and governmental levies
except such as are contested in good faith and by appropriate proceedings or where the failure to effect such payment is not adverse
in any material respect to the Holders of the Notes.

Section 4.06         Stay,
Extension and Usury Laws.


 


Each of the Issuers
and each of the Guarantors covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, plead,
or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or
at any time hereafter in force, that may affect the covenants or the performance of this Indenture; and each of the Issuers and
each of the Guarantors (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such
law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted
to the Trustee, but will suffer and permit the execution of every such power as though no such law has been enacted.


 


Section 4.07         Restricted
Payments.


 


(a)          The
Parent will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly:


 


(1)         declare
or pay any dividend or make any other payment or distribution on account of the Parent’s or any of its Restricted Subsidiaries’
Equity Interests (including, without limitation, any payment in connection with any merger or consolidation involving the Parent
or any of its Restricted Subsidiaries) or to the direct or indirect holders of the Parent’s or any of its Restricted Subsidiaries’
Equity Interests in their capacity as such (other than dividends or distributions payable in Equity Interests (other than Disqualified
Stock) of the Parent or payable to the Parent or a Restricted Subsidiary of the Parent);


 


(2)          purchase,
redeem or otherwise acquire or retire for value (including, without limitation, in connection with any merger or consolidation
involving the Parent) any Equity Interests of the Parent or any direct or indirect parent of the Parent;


 


(3)          make any payment on or with respect to, or purchase, redeem, defease or otherwise acquire or retire for value any
Indebtedness that is subordinated in right of payment to the Notes or the Note Guarantees (excluding any intercompany Indebtedness
between or among the Parent and any of its Restricted Subsidiaries), except (a) a payment of interest when due or (b) a payment
of principal at or within one year of the Stated Maturity thereof; or


 


(4)          make
any Restricted Investment (all such payments and other actions set forth in these clauses (1) through (4) above being collectively
referred to as “Restricted Payments”),


 


unless, at the time of and after
giving effect to such Restricted Payment,


 


(A)         no Default (except a Reporting Default) or Event of Default shall have occurred and be continuing or shall occur as a consequence
thereof;


 


(B)         the Parent is permitted to incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test
set forth in Section 4.09(a); and


 


(C)         the amount of such Restricted Payment, when added to the aggregate amount of all other Restricted Payments made after the
Prior Issue Date (other than Restricted Payments made pursuant to clauses (2) through (10) and clause (12) of Section 4.07(b)),
would not exceed the sum of (without duplication):


 






    	 	47	 



     


    

 


(i)           50.0% of Consolidated Net Income of the Parent and its Restricted Subsidiaries for the period (taken as one accounting period)
commencing on January 1, 2019 to and including the last day of the fiscal quarter ended immediately prior to the date of such calculation
for which consolidated financial statements are available (or, if such Consolidated Net Income shall be a deficit, minus 100.0%
of such deficit), plus


 


(ii)          the
sum of (A) the aggregate net cash proceeds received by the Parent since the Prior Issue Date as a contribution to its common equity
capital (other than from a Restricted Subsidiary of the Parent) or from the issue or sale of Equity Interests of the Parent (other
than Disqualified Stock) or from the issue or sale of convertible or exchangeable Disqualified Stock or convertible or exchangeable
debt securities of the Parent that have been converted into or exchanged for such Equity Interests (other than Equity Interests
(or Disqualified Stock or debt securities) sold to a Restricted Subsidiary of the Parent), and (B) the Fair Market Value of any
Permitted Business or long-term tangible assets that are useful in a Permitted Business to the extent acquired in consideration
of Equity Interests of the Parent (other than Disqualified Equity) since the Prior Issue Date, plus


 


(iii)         to
the extent that any Restricted Investment that was made since the Prior Issue Date is sold for cash or otherwise liquidated or
repaid for cash, the cash return of capital with respect to such Restricted Investment (less the cost of disposition, if any),
plus


 


(iv)         the amount equal to the net reduction in Restricted Investments made by the Parent or any of its Restricted Subsidiaries
in any Person since the Prior Issue Date resulting from:


 


(A)        dividends,
repayments of loans or advances, or other transfers of assets, in each case, to the Parent or any Restricted Subsidiary of the
Parent from any Person (including, without limitation, any Unrestricted Subsidiary of the Parent); or


 


(B)         the
redesignation of Unrestricted Subsidiaries of the Parent as Restricted Subsidiaries (valued in each case as provided in the definition
of “Investment”).


 


(b)          The
preceding provisions will not prohibit:


 


(1)          the
payment of any dividend or distribution within 60 days after the date of its declaration, if at the date of declaration the payment
would have complied with the provisions of this Indenture;


 


(2)          the purchase, redemption, defeasance or other acquisition or retirement of any subordinated Indebtedness of the Company
or any Guarantor or of any Equity Interests of the Parent in exchange for, or out of the net cash proceeds of the substantially
concurrent (a) contribution (other than from a Restricted Subsidiary of the Parent) to the equity capital of the Parent or (b)
sale (other than to a Restricted Subsidiary of the Parent) of, Equity Interests of the Parent (other than Disqualified Stock),
with a sale being deemed substantially concurrent if such purchase, redemption, defeasance or other acquisition or retirement occurs
not more than 120 days after such sale; provided, however, that the amount of any such net cash proceeds that are utilized
for any such purchase, redemption, defeasance or other acquisition or retirement will not be considered net proceeds for purposes
of Section 4.07(a)(C)(ii);


 






    	 	48	 



     


    

 


(3)          the purchase, redemption, defeasance or other acquisition or retirement of subordinated Indebtedness of the Company
or any Guarantor with the net cash proceeds from a substantially concurrent incurrence of, or in exchange for, Permitted Refinancing
Indebtedness;


 


(4)          the
payment of any dividend or distribution by a Restricted Subsidiary of the Parent to the holders of its Equity Interests (other
than Disqualified Stock) on a pro rata basis;


 


(5)          so
long as no Default (except a Reporting Default) or Event of Default has occurred and is continuing or would be caused thereby,

Subsidiary of the Parent held by any current or former officer, director or employee of the Parent, any of its Restricted Subsidiaries
pursuant to any director or employee equity subscription agreement or equity option agreement or other employee benefit plan or
to satisfy obligations under any Equity Interests appreciation rights or option plan or similar arrangement; provided, however,
that the aggregate price paid for all such purchased, redeemed, acquired or retired Equity Interests may not exceed $10.0 million
in any calendar year, with any portion of such $10.0 million amount that is unused in a calendar year to be carried forward to
successive calendar years and added to such amount;


 


(6)          the
purchase or other acquisition of Equity Interests deemed to occur upon the exercise of unit options, warrants, incentives, rights
to acquire Equity Interests or other convertible securities if such Equity Interests represent a portion of the exercise or exchange
price thereof, and any purchase or other acquisition of Equity Interests made in lieu of withholding taxes in connection with
any exercise or exchange of unit options, warrants, incentives or rights to acquire Equity Interests;


 


(7)          payments
or distributions to dissenting unitholders or shareholders not to exceed $10.0 million in the aggregate since the Prior Issue
Date (x) pursuant to applicable law or (y) in connection with the settlement or other satisfaction of legal claims made pursuant
to or in connection with a consolidation, merger or transfer of assets that is not prohibited by this Indenture;


 


(8)         cash payments in lieu of the issuance of fractional units or shares;


 


(9)         so
long as no Default (other than a Reporting Default) or Event of Default has occurred and is continuing or would be caused thereby,
the declaration and payment of scheduled or accrued dividends to holders of any class of or series of Disqualified Stock of the
Parent issued since the Prior Issue Date, in accordance with Section 4.09, to the extent such dividends are included in Fixed
Charges;


 


(10)       so long as no Default (other than a Reporting Default) or Event of Default has occurred and is continuing or would
be caused thereby, the purchase, redemption, defeasance or other acquisition or retirement for value of any subordinated Indebtedness
of the Issuers or the Guarantors (i) at a purchase price not greater than 101% of the principal amount of such subordinated Indebtedness
in the event of a Change of Control in accordance with provisions similar to those set forth in Section 4.15 hereof or (ii) at
a purchase price not greater than 100% of the principal amount thereof in accordance with provisions similar to those set forth
in Section 4.10 hereof; provided that, prior to or simultaneously with such purchase, redemption, defeasance or other acquisition
or retirement for value, the Company has made the Change of Control Offer or Asset Sale Offer, as applicable, as provided in such
covenant with respect to the Notes and has completed the purchase of all Notes validly tendered for payment (and not withdrawn)
in connection with such Change of Control Offer or Asset Sale Offer;


 






    	 	49	 



     


    

 


(11)       so
long as no Default (other than a Reporting Default) or Event of Default has occurred and is continuing or would be caused thereby,
cash dividends and repurchases of the Parent’s Equity Interests in a combined amount up to $100.0 million in any 12-month
period following the Prior Issue Date, with any portion of such $100.0 million amount that is unused in a given 12-month period
following the Prior Issue Date, less the amount of any cash dividends and repurchases of the Parent’s Equity Interests made
pursuant to clause (12) below during such 12-month period, to be carried forward to successive 12-month periods and added to such
amount; or


 


(12)       so
long as no Default (other than a Reporting Default) or Event of Default has occurred and is continuing or would be caused thereby,
any cash dividend or repurchase of the Parent’s Equity Interests, so long as, after giving pro forma effect to the payment
of any such dividend or such repurchase and any incurrence of Indebtedness in connection therewith, the Consolidated Leverage
Ratio as of the date of such dividend or repurchase (which, for the avoidance of doubt, shall be the date of determination for
the calculation of the Consolidated Leverage Ratio under this clause (12)) would be no greater than 4.00:1.0.


 


The amount of all Restricted
Payments (other than cash) will be the Fair Market Value, determined as of the date the Restricted Payment (or, in the case of
a dividend, on the date of declaration) is proposed to be paid, the Restricted Investment is proposed to be made or the asset(s)
or securities are proposed to be transferred or issued by the Parent or such Restricted Subsidiary, as the case may be, pursuant
to such Restricted Payment, except that the Fair Market Value of any non-cash dividend or distribution made within 60 days after
the date of declaration shall be determined as of such date. For purposes of determining compliance with this Section 4.07, in
the event that a Restricted Payment meets the criteria of more than one of the categories of Restricted Payments described in the
preceding clauses (1) through (12) of Section 4.07(b), the Parent will be permitted to classify (or later classify or reclassify
in whole or in part in its sole discretion) such Restricted Payment in any manner that complies with this Section 4.07.


 


Section 4.08        Dividend
and Other Payment Restrictions Affecting Restricted Subsidiaries.


 


(a)          The Parent will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create or permit
to exist or become effective any consensual encumbrance or restriction on the ability of any Restricted Subsidiary to:


 


(1)         pay dividends or make any other distributions on its Capital Stock to the Parent or any of its Restricted Subsidiaries,
or pay any Indebtedness or other obligations owed to the Parent or any of its Restricted Subsidiaries; provided that the
priority that any series of preferred stock of a Restricted Subsidiary has in receiving dividends or liquidating distributions
before dividends or liquidating distributions are paid in respect of common stock of such Restricted Subsidiary shall not constitute
a restriction on the ability to make dividends or distributions on Capital Stock for purposes of this Section 4.08, provided
that the terms of such preferred stock do not expressly restrict the ability of such Restricted Subsidiary to pay dividends or
make distributions on its Capital Stock;


 


(2)          make loans or advances to the Parent or any of its Restricted Subsidiaries (it being understood that the subordination
of loans or advances made to the Parent or any of its Restricted Subsidiaries to other Indebtedness incurred by the Parent or any
of its Restricted Subsidiaries shall not be deemed a restriction on the ability to make loans or advances); or


 






    	 	50	 



     


    

 


(3)          transfer any of its properties or assets to the Parent or any of its Restricted Subsidiaries.


 


(b)          The restrictions in Section 4.08(a) hereof will not apply to encumbrances or restrictions existing under or by reason of:


 


(1)         agreements
as in effect on the date of this Indenture and any amendments, modifications, restatements, renewals, increases, supplements,
refundings, replacements or refinancings of those agreements or the Indebtedness to which they relate, provided that the
amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings are no more
restrictive, taken as a whole, with respect to such dividend, distribution and other payment restrictions than those contained
in those agreements on the date of this Indenture;


 


(2)          this Indenture, the Notes and the Note Guarantees;


 


(3)          applicable
law;


 


(4)         any
instrument governing Indebtedness or Capital Stock of a Person acquired by the Parent or any of its Restricted Subsidiaries as
in effect at the time of such acquisition, which encumbrance or restriction is not applicable to any Person, or the properties
or assets of any Person, other than the Person, or the property or assets of the Person, so acquired, provided that, in
the case of Indebtedness, such Indebtedness was otherwise permitted by the terms of this Indenture to be incurred;


 


(5)         customary non-assignment provisions in equipment or other licenses, easements, leases or similar instruments, in
each case entered into in the ordinary course of business and consistent with past practices;


 


(6)         Capital
Lease Obligations, mortgage financings or purchase money obligations, in each case for property acquired in the ordinary course
of business that impose restrictions on that property of the nature described in clause (3) of the preceding paragraph;


 


(7)         any agreement for the sale or other disposition of a Restricted Subsidiary of the Parent that restricts distributions
by that Restricted Subsidiary pending its sale or other disposition;


 


(8)         Permitted Refinancing Indebtedness, provided that the restrictions contained in the agreements governing such
Permitted Refinancing Indebtedness are no more restrictive, taken as a whole, than those contained in the agreements governing
the Indebtedness being refinanced;


 


(9)         Liens securing Indebtedness otherwise permitted to be incurred under the provisions of Section 4.12 that limit the
right of the debtor to dispose of the assets subject to such Liens;


 


(10)       provisions limiting the disposition or distribution of assets or property in joint venture agreements, asset sale
agreements, stock sale agreements and other similar agreements entered into in the ordinary course of business, which limitations
are applicable only to the assets or property that is the subject of such agreements;


 


(11)       any
agreement or instrument relating to any property or assets acquired after the date of this Indenture, so long as such encumbrance
or restriction relates only to the property or assets so acquired and is not and was not created in anticipation of such acquisitions;


 






    	 	51	 



     


    

 


(12)       Hedging
Contracts permitted from time to time under this Indenture;


 


(13)        restrictions
on cash, Cash Equivalents or other deposits or net worth imposed by customers under contracts entered into in the ordinary course
of business;


 


(14)       with
respect to any Foreign Subsidiary, any encumbrance or restriction contained in the terms of any Indebtedness or any agreement
pursuant to which such Indebtedness was incurred if either (a) the encumbrance or restriction applies only in the event of a payment
default or a default with respect to a financial covenant in such Indebtedness or agreement or (b) the Parent determines that
any such encumbrance or restriction will not materially affect the Company’s ability to make principal or interest payments
on the Notes, as determined in good faith by the Board of Directors of the Parent, whose determination shall be conclusive; and


 


(15)       any
other agreement governing Indebtedness of the Issuers or any Guarantor that is permitted to be incurred under Section 4.09; provided,
however, that such encumbrances or restrictions are not materially more restrictive, taken as a whole, than those contained
in this Indenture or the Credit Agreement as in effect on the date of this Indenture.


 


Section 4.09        Incurrence
of Indebtedness and Issuance of Preferred Stock.


 


(a)          The
Parent will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume,
Guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “incur”)
any Indebtedness (including Acquired Debt); the Parent will not, and will not permit any of its Restricted Subsidiaries to, issue
any Disqualified Stock; and the Parent will not permit any of its Restricted Subsidiaries to issue any other preferred securities;
provided, however, that the Parent, the Issuers and any Guarantor may incur Indebtedness (including Acquired Debt) or issue
Disqualified Stock and the Issuers and any Restricted Subsidiary of the Parent that is a Guarantor may issue other preferred securities,
if, for the Parent’s most recently ended four full fiscal quarters for which internal financial statements are available
immediately preceding the date on which such additional Indebtedness is incurred or such Disqualified Stock or other preferred
securities are issued, the Fixed Charge Coverage Ratio would have been at least 2.00 to 1.0, determined on a pro forma
basis (including a pro forma application of the net proceeds therefrom), as if the additional Indebtedness had been incurred
or Disqualified Stock or other preferred securities had been issued, as the case may be, at the beginning of such four-quarter
period.


 


(b)          Section 4.09(a) will not prohibit the incurrence of any of the following items of Indebtedness (collectively, “Permitted
Debt”) or the issuance of any preferred securities described in clauses (10) or (12) below:


 


(1)          the incurrence by the Parent or any of its Restricted Subsidiaries of Indebtedness under one or more Credit Facilities,
provided that, after giving effect to any such incurrence, the aggregate principal amount of all Indebtedness incurred under
this clause (1) (with letters of credit being deemed to have a principal amount equal to the maximum potential liability of the
Parent and its Subsidiaries thereunder) and then outstanding does not exceed the greater of (a) $1.25 billion or (b) $800.0 million
plus 25.0% of the Parent’s Consolidated Net Tangible Assets determined as of the date of such incurrence;


 


(2)          the
incurrence by the Parent or its Restricted Subsidiaries of the Existing Indebtedness;


 






    	 	52	 



     


    

 


(3)          the
incurrence by the Issuers and the Guarantors of Indebtedness represented by the Initial Notes and the related Note Guarantees
to be issued on the date of this Indenture;


 


(4)          the
incurrence by the Parent or any of its Restricted Subsidiaries of Indebtedness represented by Capital Lease Obligations, mortgage
financings or purchase money obligations, in each case, incurred for the purpose of financing all or any part of the purchase
price or cost of construction or improvement of property, plant or equipment used in the business of the Parent or such Restricted
Subsidiary, including all Permitted Refinancing Indebtedness incurred to extend, refinance, renew, replace, defease or refund
any Indebtedness incurred pursuant to this clause (4), provided that after giving effect to any such incurrence, the principal
amount of all Indebtedness incurred pursuant to this clause (4) and then outstanding does not exceed the greater of (a) $50.0
million and (b) 2.5% of the Parent’s Consolidated Net Tangible Assets determined as of the date of such incurrence;


 


(5)          the incurrence by the Parent or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange
for, or the net proceeds of which are used to, extend, refinance, renew, replace, defease or refund Indebtedness of the Parent
or any of its Restricted Subsidiaries (other than intercompany Indebtedness), in each case, that was permitted by this Indenture
to be incurred under the first paragraph of this Section 4.09 or clause (2), (3) or (12) of this Section 4.09(b) or this clause
(5);


 


(6)          the
incurrence by the Parent or any of its Restricted Subsidiaries of intercompany Indebtedness between or among the Parent and any
of its Restricted Subsidiaries; provided, however, that:


 


(A)         if
the Company is the obligor on such Indebtedness and a Guarantor is not the obligee, such Indebtedness must be expressly subordinated
to the prior payment in full in cash of all Obligations with respect to the Notes, or if a Guarantor is the obligor on such Indebtedness
and neither the Company nor another Guarantor is the obligee, such Indebtedness must be expressly subordinated to the prior payment
in full in cash of all Obligations with respect to the Note Guarantee of such Guarantor; and


 


(B)         (i) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person
other than the Parent or a Restricted Subsidiary of the Parent and (ii) any sale or other transfer of any such Indebtedness to
a Person that is neither the Parent nor a Restricted Subsidiary of the Parent will be deemed, in each case, to constitute an incurrence
of such Indebtedness by the Parent or such Restricted Subsidiary, as the case may be, that was not permitted by this clause (6);


 


(7)          the incurrence by the Parent or any of its Restricted Subsidiaries of obligations under Hedging Contracts in the
ordinary course of business and not for speculative purposes;


 


(8)          the
Guarantee by the Parent or any of its Restricted Subsidiaries of Indebtedness of the Parent or any of its Restricted Subsidiaries
that was permitted to be incurred by another provision of this Section 4.09; provided that in the event such Indebtedness
being Guaranteed is subordinated in right of payment to the Notes or the Note Guarantees, then the Guarantee shall be subordinated
in right of payment to the Notes or the Note Guarantees, as the case may be;


 


(9)          the incurrence by the Parent or any of its Restricted Subsidiaries of Indebtedness in respect of bid, performance,
surety and similar bonds issued for the account of the Parent and any of its Restricted Subsidiaries in the ordinary course of
business, including Guarantees and obligations of the Parent or any of its Restricted Subsidiaries with respect to letters of credit
supporting such obligations (in each case other than an obligation for money borrowed);


 






    	 	53	 



     


    

 


(10)        the
issuance by any of the Parent’s Restricted Subsidiaries to the Parent or to any of its Restricted Subsidiaries of any preferred
securities; provided, however, that:


 


(A)        any subsequent issuance or transfer of Equity Interests that results in any such preferred securities being held by a Person
other than the Parent or a Restricted Subsidiary of the Parent, and


 


(B)         any sale or other transfer of any such preferred securities to a Person that is not either the Parent or a Restricted Subsidiary
of the Parent


 


shall be deemed,
in each case, to constitute an issuance (as of the date of such issuance, sale or transfer) of such preferred securities by such
Restricted Subsidiary that was not permitted by this clause (10);


 


(11)        the incurrence by the Parent or any of its Restricted Subsidiaries of liability in respect of the Indebtedness of
any Unrestricted Subsidiary of the Parent or any Joint Venture but only to the extent that such liability is the result of the
Parent’s or any such Restricted Subsidiary’s being a general partner of such Unrestricted Subsidiary or Joint Venture
and not as guarantor of such Indebtedness and provided that, after giving effect to any such incurrence, the aggregate principal
amount of all Indebtedness incurred under this clause (11) and then outstanding does not exceed $10.0 million;


 


(12)        the incurrence by the Parent or any of its Restricted Subsidiaries of Permitted Acquisition Indebtedness; and


 


(13)        the
incurrence by the Parent or any of its Restricted Subsidiaries of additional Indebtedness, provided that, after giving
effect to any such incurrence, the aggregate principal amount of all Indebtedness incurred under this clause (13) and then outstanding
does not exceed the greater of (a) $100.0 million and (b) 5.0% of the Parent’s Consolidated Net Tangible Assets determined
as of the date of such incurrence.


 


For purposes of determining
compliance with this Section 4.09, in the event that an item of Indebtedness (including Acquired Debt) meets the criteria of more
than one of the categories of Permitted Debt described in clauses (1) through (13) above, or is entitled to be incurred pursuant
to the first paragraph of this Section 4.09, the Parent will be permitted to classify (or later classify or reclassify in whole
or in part in its sole discretion) such item of Indebtedness in any manner that complies with this Section 4.09. Any Indebtedness
under Credit Facilities on the date of this Indenture shall be considered incurred under the first paragraph of this Section 4.09
and may not be reclassified.


 


The accrual of interest,
the accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional
Indebtedness with the same terms, and the payment of dividends on Disqualified Stock in the form of additional shares of the same
class of Disqualified Stock will not be deemed to be an incurrence of Indebtedness or an issuance of Disqualified Stock for purposes
of this Section 4.09, provided, in each such case, that the amount thereof is included in Fixed Charges of the Parent as
accrued. For purposes of this Indenture, (a) unsecured Indebtedness of any Person will not be deemed to be subordinated in
right of payment to secured Indebtedness of that Person merely because it is unsecured and (b) Indebtedness of the Parent
will not be deemed to be subordinated in right of payment to Indebtedness of a Restricted Subsidiary merely because it is structurally
subordinated thereto. Further, the accounting reclassification of any obligation of the Parent or any of its Restricted Subsidiaries
as Indebtedness will not be deemed an incurrence of Indebtedness for purposes of this Section 4.09.


 






    	 	54	 



     


    

 


For purposes of determining
compliance with any U.S. dollar-denominated restriction on the incurrence of Indebtedness, the U.S. dollar-equivalent principal
amount of Indebtedness denominated in a foreign currency shall be calculated based on the relevant currency exchange rate in effect
on the date such Indebtedness was incurred, in the case of term Indebtedness, or first committed, in the case of revolving credit
Indebtedness; provided that if such Indebtedness is incurred to refinance other Indebtedness denominated in a foreign currency,
and such refinancing would cause the applicable U.S. dollar-dominated restriction to be exceeded if calculated at the relevant
currency exchange rate in effect on the date of such refinancing, such U.S. dollar-dominated restriction shall be deemed not to
have been exceeded so long as the principal amount of such refinancing Indebtedness does not exceed the principal amount of such
Indebtedness being refinanced. Notwithstanding any other provision of this Section 4.09, the maximum amount of Indebtedness that
the Parent and its Restricted Subsidiaries may incur pursuant to this Section 4.09 shall not be deemed to be exceeded solely as
a result of fluctuations in the exchange rate of currencies. The principal amount of any Permitted Refinancing 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 Permitted Refinancing Indebtedness is denominated that is in effect on the date of such
refinancing.


 


Section 4.10         Asset
Sales.


 


The Parent will not,
and will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless:


 


(1)          the
Parent (or a Restricted Subsidiary of the Parent, as the case may be) receives consideration at the time of the Asset Sale at
least equal to the Fair Market Value (measured as of the date of the definitive agreement with respect to such Asset Sale) of
the assets or Equity Interests issued or sold or otherwise disposed of;


 


(2)          the Fair Market Value is determined by (a) an Officer of the Parent if the value is less than $40.0 million and evidenced
by an Officers’ Certificate delivered to the Trustee, or (b) the Board of Directors of the Parent if the value is $40.0 million
or more and evidenced by a Board Resolution delivered to the Trustee; and


 


(3)         at least 75% of the aggregate consideration received by the Parent and its Restricted Subsidiaries in the Asset Sale
and all other Asset Sales since the Prior Issue Date is in the form of cash or Cash Equivalents or a combination thereof. For purposes
of this provision, each of the following will be deemed to be cash:


 


(A)        any liabilities, as shown on the Parent’s most recent consolidated balance sheet, of the Parent or any of its Restricted
Subsidiaries (other than contingent liabilities and liabilities that are by their terms subordinated to the Notes or any Note Guarantee)
that are assumed by the transferee of any such assets pursuant to a customary novation agreement that releases the Parent or such
Restricted Subsidiary from further liability;


 


(B)         any
securities, notes or other obligations received by the Parent or any Restricted Subsidiary from such transferee that are, within
180 days after the Asset Sale, converted by the Parent or such Restricted Subsidiary into cash, to the extent of the cash received
in that conversion;


 






    	 	55	 



     


    

 


(C)         any stock or assets of the kind referred to in clause (2), (3) or (5) of the next succeeding paragraph of this Section 4.10
received by the Parent or any of its Restricted Subsidiaries in connection with such transaction; and


 


(D)        any Designated Non-cash Consideration received by the Parent or any of its Restricted Subsidiaries in such Asset Sale having
an aggregate Fair Market Value, taken together with all other Designated Non-cash Consideration received since the date of this
Indenture pursuant to this clause (d) that at the time has not been converted to cash, not to exceed the greater of (x) $50.0 million
and (y) 2.5% of the Parent’s Consolidated Net Tangible Assets at the time of the receipt of such Designated Non-cash Consideration,
with the Fair Market Value of each item of Designated Non-cash Consideration being measured at the time received and without giving
effect to subsequent changes in value.


 


Within 360 days after
the receipt of any Net Proceeds from an Asset Sale, the Parent or any Restricted Subsidiary may apply those Net Proceeds at its
option to any combination of the following:


 


(1)          to repay, purchase, redeem or otherwise retire Senior Debt (and in the case of repaying Senior Debt under any revolving
credit agreement to permanently reduce commitments thereunder by a corresponding amount);


 


(2)          to
acquire all or substantially all of the properties or assets of a Person primarily engaged in a Permitted Business;


 


(3)          to acquire a majority of the Voting Stock of a Person primarily engaged in a Permitted Business;


 


(4)          to make capital expenditures; or


 


(5)          to acquire other long-term assets that are used or useful in a Permitted Business.


 


The requirement of
clause (2), (3), (4) or (5) of the preceding paragraph of this Section 4.10 shall be deemed to be satisfied if a bona fide binding
contract committing to make the investment, acquisition or expenditure referred to therein is entered into by the Parent or any
of its Restricted Subsidiaries with a Person other than an Affiliate of the Parent within the time period specified in the preceding
paragraph and such Net Proceeds are subsequently applied in accordance with such contract within six months following the date
such agreement is entered into.


 


Pending the final application
of any Net Proceeds, the Parent or any Restricted Subsidiary may temporarily reduce revolving credit borrowings or otherwise invest
the Net Proceeds in any manner that is not prohibited by this Indenture. Any Net Proceeds from Asset Sales that are not applied
or invested as provided in the preceding paragraph will constitute “Excess Proceeds.”


 


On the 361st day after
the Asset Sale (or at the Company’s option, any earlier date), if the aggregate amount of Excess Proceeds then exceeds $25.0
million, the Company will make an Asset Sale Offer to all Holders of Notes (with a copy to the Trustee), and all holders of other
Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in this Section 4.10 with
respect to offers to purchase, prepay or redeem with the proceeds of sales of assets, to purchase, prepay or redeem, on a pro rata
basis (except that any Notes represented by a Note in global form will be selected by such method as DTC may require), the maximum
principal amount of Notes and such other pari passu Indebtedness that may be purchased, prepaid or redeemed out of the Excess
Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of the principal amount plus accrued and unpaid interest,
if any, to the date of settlement, subject to the right of Holders on the relevant record date to receive interest due on an interest
payment date that is on or prior to the date of settlement, and will be payable in cash. If any Excess Proceeds remain after consummation
of an Asset Sale Offer, the Parent or any of its Restricted Subsidiaries may use those Excess Proceeds for any purpose not otherwise
prohibited by this Indenture. If the aggregate principal amount of Notes tendered into such Asset Sale Offer exceeds the amount
of Excess Proceeds allocated to the purchase of Notes, the Trustee will select the Notes to be purchased on a pro rata basis (except
that any Notes represented by a Note in global form will be selected by such method as DTC may require). Upon completion of each
Asset Sale Offer, the amount of Excess Proceeds will be reset at zero.


 






    	 	56	 



     


    

 


The Company will comply
with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent
those laws and regulations are applicable in connection with each repurchase of Notes pursuant to an Asset Sale Offer. To the extent
that the provisions of any securities laws or regulations conflict with Section 3.09 or this Section 4.10, the Company will comply
with the applicable securities laws and regulations and will not be deemed to have breached its obligations under Section 3.09
or this Section 4.10 by virtue of such conflict.


 


Section 4.11         Transactions
with Affiliates.


 


(a)          The
Parent will not, and will not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise
dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction,
contract, agreement, understanding, loan, advance or Guarantee with, or for the benefit of, any Affiliate (each, an “Affiliate
Transaction”), involving aggregate payments or consideration in excess of $10.0 million unless:


 


(1)          the Affiliate Transaction is on terms that are no less favorable to the Parent or the relevant Restricted Subsidiary
than those that would have been obtained in a comparable transaction by the Parent or such Restricted Subsidiary with an unrelated
Person; and


 


(2)          the Parent delivers to the Trustee, with respect to any Affiliate Transaction or series of related Affiliate Transactions
involving aggregate consideration in excess of $50.0 million, an Officers’ Certificate certifying that such Affiliate Transaction
or series of related Affiliate Transactions complies with this Section 4.11 and that such Affiliate Transaction or series of related
Affiliate Transactions has been approved by a majority of the disinterested members of the Board of Directors of the Parent.


 


(b)          The
following items will not be deemed to be Affiliate Transactions and, therefore, will not be subject to the provisions of Section
4.11(a) hereof:


 


(1)         any
employment agreement, customary benefit program or arrangement, equity award, equity option or equity appreciation agreement or
plan entered into by the Parent or any of its Restricted Subsidiaries with or for the benefit of officers, directors or employees
of the Parent, any of its Restricted Subsidiaries in the ordinary course of business;


 


(2)          transactions between or among any of the Parent and its Restricted Subsidiaries, including between any Restricted
Subsidiaries;


 


(3)          transactions with a Person (other than an Unrestricted Subsidiary of the Parent) that is an Affiliate of the Parent
solely because the Parent owns, directly or through one of its Restricted Subsidiaries, an Equity Interest in such Person;


 






    	 	57	 



     


    

 


(4)         customary
compensation, indemnification and other benefits made available to officers, directors or employees of the Parent or any of its
Restricted Subsidiaries, including reimbursement or advancement of out-of-pocket expenses and provisions of officers’ and
directors’ liability insurance;


 


(5)         sales
of Equity Interests (other than Disqualified Stock) to, or receipt of capital contributions from, Affiliates of the Parent;


 


(6)         Permitted
Investments or Restricted Payments that are permitted by the provisions of this Indenture in Section 4.07;


 


(7)          in
the case of contracts for buying and selling or leasing equipment or inventory or other operational contracts, any such contracts
that are entered into in the ordinary course of business on terms substantially similar to those contained in similar contracts
entered into by the Parent or any of its Restricted Subsidiaries and unrelated third parties; and


 


(8)         any
transaction in which the Parent or any of its Restricted Subsidiaries, as the case may be, delivers to the Trustee a letter from
an accounting, appraisal or investment banking firm of national standing stating that such transaction is fair to the Parent or
such Restricted Subsidiary from a financial point of view or that such transaction meets the requirements of Section 4.11(a)(1).


 


Section 4.12         Liens.


 


The Parent will not
and will not permit any of its Restricted Subsidiaries to, create, incur, assume or otherwise cause or suffer to exist or become
effective any Lien of any kind (other than Permitted Liens) securing Indebtedness upon any of their property or assets, now owned
or hereafter acquired, unless the Notes or any Note Guarantee of the Parent or such Restricted Subsidiary, as applicable, is secured
on an equal and ratable basis with (or on a senior basis to, in the case of obligations subordinated in right of payment to the
Notes or such Note Guarantee, as the case may be) the obligations so secured until such time as such obligations are no longer
secured by a Lien.


 


Section 4.13         Finance
Corp. Activities.


 


Finance Corp. may not
incur Indebtedness unless (1) the Company is a co-obligor or guarantor of such Indebtedness or (2) the net proceeds of such Indebtedness
are loaned to the Parent or any of its Restricted Subsidiaries, used to acquire outstanding debt securities issued by the Parent
or used to repay Indebtedness of the Parent or any of its Restricted Subsidiaries as permitted under Section 4.09. Finance Corp.
may not engage in any business not related directly or indirectly to obtaining money or arranging financing for the Parent or its
Restricted Subsidiaries.


 


Section 4.14         Parent
Existence.


 


Subject to Article
5 and Section 10.04 hereof, the Parent and the Issuers shall do or cause to be done all things necessary to preserve and keep in
full force and effect:


 


(1)          their respective corporate or partnership existence, as applicable, and the corporate, partnership or other existence
of each other Restricted Subsidiary of the Parent, in accordance with the respective organizational documents (as the same may
be amended from time to time) of the Parent, the Issuers or any such other Restricted Subsidiary of the Parent; and


 






    	 	58	 



     


    

 


(2)          the rights (charter and statutory), licenses and franchises of the Parent and its Restricted Subsidiaries; provided,
however, that the Parent shall not be required to preserve any such right, license or franchise, or the corporate, partnership
or other existence of any of its Restricted Subsidiaries (other than the Issuers), if the Parent shall determine that the preservation
thereof is no longer desirable in the conduct of the business of the Parent and its Restricted Subsidiaries, taken as a whole,
and that the loss thereof is not adverse in any material respect to the Holders of the Notes.


 


Section 4.15        Offer
to Repurchase Upon Change of Control.


 


(a)          Upon the occurrence of a Change of Control, the Company will make an offer (a “Change of Control Offer”)
to each Holder to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of that Holder’s
Notes at a purchase price in cash equal to 101% of the aggregate principal amount of Notes repurchased, plus accrued and unpaid
interest, if any, on the Notes repurchased to the date of settlement (the “Change of Control Settlement Date”),
subject to the rights of Holders of Notes on the relevant record date to receive interest due on the relevant interest payment
date that is on or prior to the Change of Control Settlement Date. Within 30 days following any Change of Control, the Company
will send a notice to each Holder and the Trustee describing the transaction or transactions that constitute the Change of Control
and stating:


 


(1)          that
the Change of Control Offer is being made pursuant to this Section 4.15 and that all Notes tendered will be accepted for payment;


 


(2)          the purchase price and the expiration date of the Change of Control Offer, which shall be no earlier than 30 days
and no later than 60 days from the date such notice is sent;


 


(3)          that
any Note not tendered will continue to accrue interest;


 


(4)          that, unless the Company defaults in the payment of the Change of Control Payment, all Notes accepted for payment
pursuant to the Change of Control Offer will cease to accrue interest after the Change of Control Settlement Date;


 


(5)          that Holders electing to have any Notes purchased pursuant to a Change of Control Offer will be required to surrender
the Notes, with the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer
by book-entry transfer, to the Paying Agent at the address specified in the notice prior to the expiration date of the Change of
Control Offer;


 


(6)          that
Holders will be entitled to withdraw their election if the Paying Agent receives, not later than the close of business on the
second Business Day preceding the expiration date of the Change of Control Offer, a telegram, electronic image scan, facsimile
transmission or letter setting forth the name of the Holder, the principal amount of Notes delivered for purchase, and a statement
that such Holder is withdrawing its election to have the Notes purchased; and


 


(7)          that
Holders whose Notes are being purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion
of the Notes surrendered, which unpurchased portion must be equal to $2,000 in principal amount or an integral multiple of $1,000
in excess thereof.


 


The Company will comply
with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent
those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control. To
the extent that the provisions of any securities laws or regulations conflict with this Section 4.15, the Company will comply with
the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.15
by virtue of such conflict.


 






    	 	59	 



     


    

 


(b)          Promptly following the expiration of the Change of Control Offer, the Company will, to the extent lawful, accept for payment
all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer. Promptly after such acceptance, the Company
will on the Change of Control Settlement Date:


 


(1)         deposit
with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes properly tendered;
and


 


(2)         deliver
or cause to be delivered to the Trustee the Notes properly accepted together with an Officers’ Certificate stating the aggregate
principal amount of Notes or portions of Notes being purchased by the Company.


 


On the Change of Control
Settlement Date, the Paying Agent will promptly pay (but in any case not later than five Business days after the Change of Control
Settlement Date) to each Holder of Notes properly tendered the Change of Control Payment for such Notes (or, if all the Notes are
then in global form, it will make such payment through the facilities of DTC), and the Trustee will promptly authenticate and mail
(or cause to be transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the
Notes surrendered, if any; provided, however, that each new Note will be in a principal amount of $2,000 or an integral
multiple of $1,000 in excess of $2,000. The Company will publicly announce the results of the Change of Control Offer on or as
soon as practicable after the Change of Control Settlement Date.


 


(c)          Notwithstanding anything to the contrary in this Section 4.15, the Company will not be required to make a Change of Control
Offer upon a Change of Control if (1) a third party (including a Subsidiary of the Company) makes the Change of Control Offer in
the manner, at the time and otherwise in compliance with the requirements set forth in this Section 4.15 applicable to a Change
of Control Offer made by the Company and purchases all Notes properly tendered and not withdrawn under the Change of Control Offer,
(2) notice of redemption of all outstanding Notes has been given pursuant to Section 3.03 hereof, unless and until there is a default
in payment of the applicable redemption price, or (3) in connection with or in contemplation of any Change of Control, the Company
has made an offer to purchase any and all outstanding Notes validly tendered at a cash price equal to or higher than the Change
of Control Payment (an “Alternate Offer”) and has purchased all outstanding Notes properly tendered in accordance
with the terms of such Alternate Offer. Notwithstanding anything to the contrary contained herein, a Change of Control Offer by
the Company or a third party may be made in advance of a Change of Control, conditioned upon the consummation of such Change of
Control, if a definitive agreement is in place for the Change of Control at the time the Change of Control Offer is made.


 


(d)          In the event that Holders of not less than 90% of the aggregate principal amount of the outstanding Notes accept a Change
of Control Offer or Alternate Offer and the Company (or a third party making the Change of Control Offer as described in paragraph
(c) above) purchases all of the Notes held by such Holders, the Issuers will have the right, upon not less than 30 nor more than
60 days’ prior notice, given not more than 30 days following the purchase pursuant to the Change of Control Offer or Alternate
Offer described above, to redeem all of the Notes that remain outstanding following such purchase at a redemption price equal to
the Change of Control Payment plus, to the extent not included in the Change of Control Payment, accrued and unpaid interest on
the Notes that remain outstanding, to the date of redemption (subject to the right of Holders on the relevant record date to receive
interest due on an interest payment date that is on or prior to the redemption date).

Section 4.16        [Reserved].


 


Section 4.17        Additional
Note Guarantees.


 


If, after the date
of this Indenture, any Restricted Subsidiary of the Parent (other than the Issuers) that is not already a Guarantor either borrows
under the Credit Agreement or Guarantees Indebtedness incurred thereunder, or Guarantees any other Indebtedness of either of the
Issuers or any Guarantor in excess of the De Minimis Guaranteed Amount, then that Subsidiary will become a Guarantor by executing
a supplemental indenture substantially in the form of Exhibit F hereto and delivering it to the Trustee within 20 Business
Days of the date on which it Guaranteed such Indebtedness; provided, however, that the preceding shall not apply to Subsidiaries
of the Parent that have properly been designated as Unrestricted Subsidiaries in accordance with Section 4.18 for so long as they
continue to constitute Unrestricted Subsidiaries. Notwithstanding the preceding, any Note Guarantee of a Restricted Subsidiary
that was incurred pursuant to this Section 4.17 will be released in the circumstances described under Section 10.05(e).


 


Section 4.18        Designation
of Restricted and Unrestricted Subsidiaries.


 


The Board of Directors
of the Parent may designate any Restricted Subsidiary of the Parent (other than the Issuers) to be an Unrestricted Subsidiary if
that designation would not cause a Default. If a Restricted Subsidiary of the Parent is designated as an Unrestricted Subsidiary,
the aggregate Fair Market Value of all outstanding Investments owned by the Parent and its Restricted Subsidiaries in the Subsidiary
properly designated will be deemed to be either an Investment made as of the time of the designation that will reduce the amount
available for Restricted Payments under the first paragraph of Section 4.07 or represent Permitted Investments, as determined by
the Parent. That designation will only be permitted if the Investment would be permitted at that time and if the Subsidiary so
designated otherwise meets the definition of an Unrestricted Subsidiary.


 


The Board of Directors
of the Parent may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary, provided that such designation
will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of the Parent of any outstanding Indebtedness of
such Unrestricted Subsidiary and such designation will only be permitted if (1) such Indebtedness is permitted under Section 4.09,
calculated on a pro forma basis as if such designation had occurred at the beginning of the four-quarter reference period,
and Section 4.12 and (2) no Default or Event of Default with respect to Section 4.12 or any other covenant in this Indenture would
be in existence following such designation.


 


Any designation of
a Subsidiary of the Parent as an Unrestricted Subsidiary will be evidenced to the Trustee by filing with the Trustee a Board Resolution
giving effect to such designation and an Officers’ Certificate certifying that such designation complied with the preceding
conditions and was permitted by Section 4.07. If, at any time, any Unrestricted Subsidiary would fail to meet the preceding requirements
as an Unrestricted Subsidiary, it will thereafter cease to be an Unrestricted Subsidiary for purposes of this Indenture, and any
Indebtedness of such Subsidiary will be deemed to be incurred by a Restricted Subsidiary of the Parent as of such date and, if
such Indebtedness is not permitted to be incurred as of such date under Section 4.09, or if such Subsidiary is not in compliance
with any other covenants in this Indenture applicable to Restricted Subsidiaries of the Parent, a Default will have occurred under
this Indenture.

Section 4.19         Covenant
Termination.




 


Notwithstanding any
provision of this Indenture or of the Notes to the contrary, if at any time (a) the rating assigned to the Notes by both of the
Ratings Agencies is an Investment Grade Rating, (b) no Default has occurred and is continuing under this Indenture and (c) the
Issuers have delivered to the Trustee an Officers’ Certificate certifying to the foregoing provisions of this sentence (the
occurrence of the events described in the foregoing clauses (a), (b) and (c) being collectively referred to as a “Covenant
Termination Event”), then, beginning on that day, the Parent and its Restricted Subsidiaries will no longer be subject to
Sections 4.07, 4.08, 4.09, 4.10, 4.11, 4.13, 4.18 and clause (4) of Section 5.01 of this Indenture and no Default or Event of Default
shall result from any failure to comply with any of the provisions of such Sections.


 


The Trustee shall not
have any obligation to monitor the ratings of the Notes, the occurrence or date of any Covenant Termination Event and may rely
conclusively on the Officers’ Certificate referenced above with respect to the same. The Trustee shall not have any obligation
to notify the Holders of the occurrence or date of any Covenant Termination Event, but may provide a copy of such Officers’
Certificate to any Holder upon request.

(4)          immediately after such reorganization no Default or Event of Default exists; and


 


(5)          such
reorganization is not materially adverse to the Holders or Beneficial Owners of the Notes (for purposes of this clause (5) a reorganization

or assets of the Company or the Parent, as applicable, in a transaction that is subject to, and that complies with the provisions
of, Section 5.01 hereof, the successor Person formed by such consolidation or into or with which the Company or the Parent, as
applicable, is merged or to which such sale, assignment, transfer, lease, conveyance or other disposition is made shall succeed
to, and be substituted for (so that from and after the date of such consolidation, merger, sale, assignment, transfer, lease, conveyance
or other disposition, the provisions of this Indenture referring to the “Company” or the “Parent” shall

DEFAULTS AND REMEDIES


 


Section 6.01        Events

(3)          failure
by the Issuers or the Parent to comply with the provisions of Section 4.10, 4.15 or 5.01 hereof;


 


(4)          failure

of the Notes then outstanding voting as a single class to comply with Section 4.03;


 


(5)          failure
by the Issuers or the Parent for 60 days after notice to the Company by the Trustee or the Holders of at least 25% in aggregate

in this Indenture;


 


(6)         default
under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any
Indebtedness for money borrowed by the Parent or any of its Restricted Subsidiaries (or the payment of which is Guaranteed by
the Parent or any of its Restricted Subsidiaries), whether such Indebtedness or Guarantee now exists, or is created after the
date of this Indenture, if that default:


 






    	 	64	 



     


    

 


(A)         is caused by a failure to pay principal of, premium on, if any, or interest on, if any, such Indebtedness prior to the expiration
of the grace period provided in such Indebtedness on the date of such default (a “Payment Default”); or


 


(B)         results in the acceleration of such Indebtedness prior to its express maturity,


 


and, in each case, the principal
amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a
Payment Default or the maturity of which has been so accelerated, aggregates $50.0 million or more; provided, however, if,
prior to any acceleration of the Notes, (i) any such Payment Default is cured or waived, (ii) any such acceleration is rescinded,
or (iii) such Indebtedness is repaid during the 20 Business Day period commencing upon the end of any applicable grace period for
such Payment Default or the occurrence of such acceleration, as the case may be, any Default or Event of Default (but not any acceleration
of the Notes) caused by such Payment Default or acceleration shall be automatically rescinded, so long as such rescission does
not conflict with any judgment, decree or applicable law;


 


(7)          failure by the Parent or any of its Restricted Subsidiaries to pay final judgments entered by a court or courts of
competent jurisdiction aggregating in excess of $50.0 million (to the extent not covered by insurance by a reputable and creditworthy

of 60 days;


 


(8)          the

court of competent jurisdiction enters an order or decree under any Bankruptcy Law that:


 


(A)         is
for relief against the Issuers or any of the Parent’s Restricted Subsidiaries that is a Significant Subsidiary or any group
of Restricted Subsidiaries of the Parent that, taken together, would constitute a Significant Subsidiary in an involuntary case;


 


(B)         appoints
a custodian of the Parent, the Issuers or any of the Parent’s Restricted Subsidiaries that is a Significant Subsidiary or
any group of Restricted Subsidiaries of the Parent that, taken together, would constitute a Significant Subsidiary or for all
or substantially all of the property of the Parent or any of its Restricted Subsidiaries that is a Significant Subsidiary or any
group of Restricted Subsidiaries of the Parent that, taken together, would constitute a Significant Subsidiary; or


 






    	 	65	 



     


    

 


(C)         orders
the liquidation of the Issuers or any of the Parent’s Restricted Subsidiaries that is a Significant Subsidiary or any group
of Restricted Subsidiaries of the Parent that, taken together, would constitute a Significant Subsidiary;


 


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


 


(10)       except as permitted by this Indenture, any Note Guarantee is held in any judicial proceeding to be unenforceable
or invalid or ceases for any reason to be in full force and effect, or any Guarantor, or any Person acting on behalf of any Guarantor,
denies or disaffirms its obligations under its Note Guarantee.


 


Section 6.02        Acceleration.


 


In the case of an Event
of Default specified in clause (8) or (9) of Section 6.01 hereof, with respect to the Parent, the Issuers, any Restricted Subsidiary
of the Parent that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Parent that, taken together, would
constitute a Significant Subsidiary, all outstanding Notes will become due and payable immediately without further action or notice.
If any other Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount
of the then outstanding Notes may declare all the Notes to be due and payable immediately.


 


Upon any such declaration,
the Notes shall become due and payable immediately.


 


The Holders of a majority
in aggregate principal amount of the then outstanding Notes by written notice to the Company and the Trustee may, on behalf of
all of the Holders of all the Notes, rescind an acceleration and its consequences hereunder, if the rescission would not conflict
with any judgment or decree and if all existing Events of Default (except nonpayment of principal of, premium on, if any, or interest
on the Notes that has become due solely because of the acceleration) have been cured or waived.


 


Section 6.03        Other
Remedies.


 


If an Event of Default
occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal of, premium on, if any,
or interest on the Notes or to enforce the performance of any provision of the Notes or this Indenture.


 


The Trustee may maintain
a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission
by the Trustee or any Holder of a Note in exercising any right or remedy accruing upon an Event of Default shall not impair the
right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative to the extent permitted
by law.


 


Section 6.04        Waiver
of Past Defaults.


 


The Holders of a majority
in aggregate principal amount of the then outstanding Notes may, on behalf of the Holders of all of the Notes, waive any existing
Default or Event of Default and its consequences hereunder, except a continuing Default or Event of Default in the payment of principal
of, premium on, if any, or interest, if any, on the Notes (including in connection with an offer to purchase any Notes). Upon notice
to the Trustee of any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed
to have been cured for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair
any right consequent thereon.


 






    	 	66	 



     


    

 


Section 6.05        Control
by Majority.


 


Holders of a majority
in aggregate principal amount of the then outstanding Notes may direct the time, method and place of conducting any proceeding
for exercising any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse
to follow any direction that conflicts with law or this Indenture that the Trustee determines may be unduly prejudicial to the
rights of other Holders of Notes (it being understood that the Trustee does not have an affirmative duty to determine whether or
not any such direction is unduly prejudicial to the rights of Holders of the Notes not joining in giving such direction) or that
may 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.


 


Section 6.06        Limitation
on Suits.


 


No Holder of a Note
may pursue any remedy with respect to this Indenture or the Notes unless:


 


(1)         such
Holder has previously given to the Trustee written notice that an Event of Default is continuing;


 


(2)         Holders
of at least 25% in aggregate principal amount of the then outstanding Notes make a written request to the Trustee to pursue the
remedy;


 


(3)         such
Holder or Holders offer and, if requested, provide to the Trustee security or indemnity satisfactory to the Trustee against any
loss, liability or expense;


 


(4)         the
Trustee does not comply with such request within 60 days after receipt of the request and the offer of security or indemnity;
and


 


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


 


A Holder of a Note
may not use this Indenture to prejudice the rights of another Holder of a Note or to obtain a preference or priority over another
Holder of a Note. The Trustee will have no duty to determine whether any Holder’s use of this Indenture complies with the
preceding sentence.


 


Section 6.07        Rights
of Holders of Notes to Receive Payment.


 


Notwithstanding any
other provision of this Indenture, the right of any Holder of a Note to receive payment of principal of, premium on, if any, or
interest, if any, on the Note, on or after the respective due dates expressed in the Note (including in connection with an offer
to purchase), or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired
or affected without the consent of such Holder.


 


Section 6.08        Collection
Suit by Trustee.


 


If an Event of Default
specified in Section 6.01(1) or (2) hereof occurs and is continuing, the Trustee is authorized to recover judgment in its own name
and as trustee of an express trust against the Issuers for the whole amount of principal of, premium on, if any, and interest,
if any, remaining unpaid on, the Notes and, to the extent lawful, interest on overdue principal and interest and such further amount
as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel.

Section 6.09        Trustee
May File Proofs of Claim.


 


The Trustee is authorized
to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the
Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and
counsel) and the Holders of the Notes allowed in any judicial proceedings relative to the Issuers (or any other obligor upon the
Notes), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or other
property payable or deliverable on any such claims and any custodian in any such judicial proceeding is hereby authorized by each
Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly
to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances
of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof. To the extent that the
payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts
due the Trustee under Section 7.07 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of
the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other
properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization
or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept
or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the
rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.


 


Section 6.10        Priorities.


 


If the Trustee collects
any money pursuant to this Article 6, it shall pay out the money in the following order:


 


First:           to
the Trustee, its agents and attorneys for amounts due under Section 7.07 hereof, including payment of all compensation, expenses
and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection;


 


Second:       to
Holders of Notes for amounts due and unpaid on the Notes for principal, premium, if any, and interest, if any, ratably, without
preference or priority of any kind, according to the amounts due and payable on the Notes for principal, premium, if any, and interest,
if any, respectively; and


 


Third:          to
the Issuers or to such party as a court of competent jurisdiction shall direct.


 


The Trustee may fix
a record date and payment date for any payment to Holders of Notes pursuant to this Section 6.10.


 


Section 6.11        Undertaking
for Costs.


 


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

Section 7.01         Duties
of Trustee.


 


(a)          If an Event of Default has occurred and is continuing, the Trustee will exercise such of the rights and powers vested in
it by this Indenture, and use the same degree of care and skill in its exercise, as a prudent man would exercise or use under the
circumstances in the conduct of his own affairs.


 


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


 


(1)          the duties of the Trustee will be determined solely by the express provisions of this Indenture and the Trustee need
perform only those duties that are specifically set forth in this Indenture and no others, 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. However, the Trustee will examine the certificates and opinions to determine whether or not they conform to the
requirements of this Indenture (but need not confirm or investigate the accuracy of any such opinions and certificates, including
mathematical calculations or other facts stated therein).


 


(c)          The
Trustee may not be relieved from liabilities for its own negligent action, its own negligent failure to act, or its own willful

paragraph does not limit the effect of paragraph (b) of this Section 7.01;

Trustee will 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 6.05 hereof.

or not therein expressly so provided, every provision of this Indenture that in any way relates to the Trustee is subject to paragraphs

provision of this Indenture will require the Trustee to expend or risk its own funds or incur any liability. The Trustee will

Holder has offered to the Trustee security and indemnity satisfactory to it against any loss, liability or expense.


 


(f)           The
Trustee will not be liable for interest on any money received by it except as the Trustee may agree in writing with the Issuers.

of Trustee.

Trustee may conclusively rely upon any document believed by it to be genuine and to have been signed or presented by the proper
Person. The Trustee need not investigate any fact or matter stated in the document.


 


(b)          Before the Trustee acts or refrains from acting, it may require an Officers’ Certificate or an Opinion of Counsel
or both. The Trustee will not be liable for any action it takes or omits to take in good faith in reliance on such Officers’
Certificate or Opinion of Counsel. The Trustee may consult with counsel of its selection and the advice of such counsel or any
Opinion of Counsel will be full and complete authorization and protection from liability in respect of any action taken, suffered
or omitted by it hereunder in good faith and in reliance thereon.


 


(c)          The
Trustee may act through its attorneys and agents and will not be responsible for the misconduct or negligence of any agent appointed

Trustee will 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 unless such Holders have offered to the Trustee indemnity or security satisfactory to it against the losses,
liabilities and expenses that might be incurred by it in compliance with such request or direction.


 


(g)          The rights, privileges, protections, immunities and benefits given to Trustee, including, without limitation, its right
to be compensated and indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder.

(including lost profits), even if the Trustee has been advised of the likelihood of such loss or damage and regardless of the
form of action.


 


(i)           The Trustee will not be deemed to have notice or knowledge of any Default or Event of Default unless a Responsible Officer
of the Trustee has actual knowledge thereof or unless written notice of any event which is in fact such a Default or Event of Default

or Event of Default under the Notes and this Indenture.


 


(j)           The
Trustee may request that the Issuers deliver an Officers’ Certificate setting forth the names of individuals and/or titles
of officers authorized at such time to take specified actions pursuant to this Indenture, which Officers’ Certificate may

any such certificate previously delivered and not superseded.


 


(k)          The
Trustee will not be required to give any bond or surety in respect of the execution of the trusts and powers under this Indenture.


 






    	 	70	 



     


    

 


(l)           Any
permissive right of the Trustee to take or refrain from taking actions enumerated in this Indenture will not be construed as a
duty.


 


Section 7.03         Individual
Rights of Trustee.


 


The Trustee in its
individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Issuers or any Affiliate
of the Company with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting
interest (as defined in the TIA after a Default has occurred and is continuing) it must eliminate such conflict within 90 days
or resign. Any Agent may do the same with like rights and duties. The Trustee is also subject to Sections 7.10 and 7.11 hereof.


 


Section 7.04         Trustee’s
Disclaimer.


 


The Trustee will not
be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Notes, it shall not be accountable
for the Issuers’ use of the proceeds from the Notes or any money paid to the Issuers or upon the Issuers’ direction
under any provision of this Indenture, it will not be responsible for the use or application of any money received by any Paying
Agent other than the Trustee, and it will not be responsible for any statement or recital herein or any statement in the Notes
or any other document in connection with the sale of the Notes or pursuant to this Indenture other than its certificate of authentication.


 


Section 7.05         Notice
of Defaults.


 


If a Default or Event
of Default occurs and is continuing and if it is known to the Trustee as provided in Section 7.02(i), the Trustee will send to
Holders of Notes a notice of the Default or Event of Default within 90 days after it occurs. Except in the case of a Default or
Event of Default in payment of principal of, premium on, if any, or interest on, any Note, the Trustee may withhold the notice
if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests
of the Holders of the Notes.


 


Section 7.06         [Reserved].


 


Section 7.07         Compensation
and Indemnity.


 


(a)          The
Company will pay to the Trustee from time to time reasonable compensation for its acceptance of this Indenture and services hereunder.
The Trustee’s compensation will not be limited by any law on compensation of a trustee of an express trust. The Company
will reimburse the Trustee promptly upon request for all reasonable disbursements, advances and expenses incurred or made by it
in addition to the compensation for its services. Such expenses will include the reasonable compensation, disbursements and expenses
of the Trustee’s agents and counsel.


 


(b)          The Issuers and the Guarantors, jointly and severally, will indemnify, defend and protect each of the Trustee and its officers,
directors, agents and employees for, and hold them harmless against, any and all losses, liabilities, damages, claims or expenses,
including taxes (other than taxes based upon, measured by or determined by the earnings or income of the Trustee) and court costs,
incurred by it arising out of or in connection with the acceptance or administration of its duties under this Indenture, including
the costs and expenses of enforcing this Indenture against the Issuers and the Guarantors (including this Section 7.07) and defending
itself against any claim (whether asserted by the Issuers, the Guarantors, any Holder or any other Person) or liability in connection
with the exercise or performance of any of its powers or duties hereunder, except to the extent any such loss, liability or expense
may be attributable to its willful misconduct or gross negligence as determined by a final, non-appealable judgment of a court
of competent jurisdiction. The Trustee will notify the Issuers promptly of any claim for which it may seek indemnity. Failure by
the Trustee to so notify the Issuers will not relieve the Issuers or any of the Guarantors of their obligations hereunder. An Issuer
or such Guarantor will defend the claim and the Trustee will cooperate in the defense. The Trustee may have separate counsel, and
the Issuers will pay the reasonable fees and expenses of such counsel. Neither an Issuer nor any Guarantor need pay for any settlement
made without its consent, which consent will not be unreasonably withheld.


 






    	 	71	 



     


    

 


(c)          The obligations of the Issuers and the Guarantors under this Section 7.07 will survive resignation or removal of the Trustee
and the satisfaction and discharge of this Indenture.


 


(d)          To
secure the Issuers’ and the Guarantors’ payment obligations in this Section 7.07, the Trustee will have a Lien prior
to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal of, premium
on, if any, or interest, if any, on, particular Notes. Such Lien will survive the satisfaction and discharge of this Indenture.


 


(e)          When
the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(8) or (9) hereof occurs, the
expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute
expenses of administration under any Bankruptcy Law.


 


Section 7.08         Replacement
of Trustee.


 


(a)          A
resignation or removal of the Trustee and appointment of a successor Trustee will become effective only upon the successor Trustee’s
acceptance of appointment as provided in this Section 7.08.


 


(b)          The
Trustee may resign in writing at any time and be discharged from the trust hereby created by so notifying the Issuers. The Holders
of a majority in aggregate principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and
the Issuers in writing at least 30 days in advance of such removal. The Issuers may remove the Trustee if:


 


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


 


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


 


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


 


(4)          the Trustee becomes incapable of acting.


 


(c)          If
the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Issuers will promptly appoint
a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in aggregate principal
amount of the then outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Issuers.


 


(d)          If
a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee
(at the Issuers’ expense), the Issuers, or the Holders of at least 10% in aggregate principal amount of the then outstanding
Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee.


 






    	 	72	 



     


    

 


(e)          If the Trustee, after written request by any Holder who has been a Holder for at least six months, fails to comply with
Section 7.10 hereof, such Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment
of a successor Trustee.


 


(f)          A
successor Trustee will deliver a written acceptance of its appointment to the retiring Trustee and to the Issuers. Thereupon,
the resignation or removal of the retiring Trustee will become effective, and the successor Trustee will have all the rights,
powers and duties of the Trustee under this Indenture. The successor Trustee will send a notice of its succession to Holders.
The retiring Trustee will promptly transfer all property held by it as Trustee to the successor Trustee; provided all sums
owing to the Trustee hereunder have been paid and subject to the Lien provided for in Section 7.07 hereof. Notwithstanding replacement
of the Trustee pursuant to this Section 7.08, the Issuers’ obligations under Section 7.07 hereof will continue for the benefit
of the retiring Trustee.


 


Section 7.09          Successor
Trustee by Merger, etc.


 


If the Trustee consolidates,
merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, the successor
corporation without any further act will be the successor Trustee.


 


Section 7.10         Eligibility;
Disqualification.


 


There will at all times
be a Trustee hereunder that is a corporation organized and doing business under the laws of the United States of America or of
any state thereof that is authorized under such laws to exercise corporate trustee power, that is subject to supervision or examination
by federal or state authorities and that has a combined capital and surplus of at least $100.0 million as set forth in its most
recent published annual report of condition.


 


Section 7.11         Preferential
Collection of Claims Against Issuers.


 


The Trustee is subject
to TIA §311(a), excluding any creditor relationship listed in TIA §311(b). A Trustee who has resigned or been removed
shall be subject to TIA §311(a) to the extent indicated therein.


 


ARTICLE 8

LEGAL DEFEASANCE AND COVENANT DEFEASANCE


 


Section 8.01         Option
to Effect Legal Defeasance or Covenant Defeasance.


 


At the option of the
Board of Directors of the Parent evidenced by a resolution set forth in an Officers’ Certificate, elect to have either Section
8.02 or 8.03 hereof be applied to all outstanding Notes upon compliance with the conditions set forth below in this Article 8.


 


Section 8.02         Legal
Defeasance and Discharge.


 


Upon the Issuers’
exercise under Section 8.01 hereof of the option applicable to this Section 8.02, the Issuers and each of the Guarantors will,
subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to have been discharged from their obligations
with respect to all outstanding Notes (including the Note Guarantees) on the date the conditions set forth below are satisfied
(hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Issuers and the Guarantors
will be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes (including the Note Guarantees),
which will thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 hereof and the other Sections
of this Indenture referred to in clauses (1) and (2) below, and to have satisfied all their other obligations under such Notes,
the Note Guarantees and this Indenture (and the Trustee, on demand of and at the expense of the Issuers, shall execute proper instruments
acknowledging the same), except for the following provisions which will survive until otherwise terminated or discharged hereunder:


 






    	 	73	 



     


    

 


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


 


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


 


(3)          the
rights, powers, trusts, duties and immunities of the Trustee hereunder and the Issuers’ and the Guarantors’ obligations
in connection therewith; and


 


(4)          this Article 8.


 


Subject to compliance
with this Article 8, the Issuers may exercise their option under this Section 8.02 notwithstanding the prior exercise of their
option under Section 8.03 hereof.


 


Section 8.03         Covenant
Defeasance.


 


Upon the Issuers’
exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Issuers and each of the Guarantors will,
subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from each of their respective obligations
under the covenants contained in Sections 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.15, 4.17 and 4.18 hereof and clause (4) of
Section 5.01(a) hereof with respect to the outstanding Notes on and after the date the conditions set forth in Section 8.04 hereof
are satisfied (hereinafter, “Covenant Defeasance”), and the Notes will thereafter be deemed not “outstanding”
for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection
with such covenants, but will continue to be deemed “outstanding” for all other purposes hereunder (it being understood
that such Notes will not be deemed outstanding for accounting purposes to the extent permitted by GAAP). For this purpose, Covenant
Defeasance means that, with respect to the outstanding Notes and Note Guarantees, the Issuers and the Guarantors may omit to comply
with and will have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly
or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant
to any other provision herein or in any other document and such omission to comply will not constitute a Default or an Event of
Default under Section 6.01 hereof, but, except as specified above, the remainder of this Indenture and such Notes and Note Guarantees
will be unaffected thereby. In addition, upon the Issuers’ exercise under Section 8.01 hereof of the option applicable to
this Section 8.03, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, Sections 6.01(3), (4), (5),
(6), (7) and (10) hereof will not constitute Events of Default.


 


Section 8.04         Conditions
to Legal or Covenant Defeasance.


 


In order to exercise
either Legal Defeasance or Covenant Defeasance under either Section 8.02 or 8.03 hereof:


 


(1)          the
Issuers must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders of the Notes, cash in U.S. dollars,
non-callable Government Securities, or a combination of cash in U.S. dollars and non-callable Government Securities, in amounts
as will be sufficient, without consideration of any reinvestment of interest, in the opinion of a nationally recognized firm of
independent public accountants, to pay the principal of, and interest and premium, if any, on, the outstanding Notes on the date
of fixed maturity or on the applicable redemption date, as the case may be, and the Issuers must specify whether the Notes are
being defeased to the date of fixed maturity or to a particular redemption date;


 






    	 	74	 



     


    

 


(2)          in the case of an election under Section 8.02 hereof, the Issuers must deliver to the Trustee an opinion of counsel
reasonably acceptable to the Trustee confirming that:


 


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


 


(B)         since
the date of this Indenture, there has been a change in the applicable federal income tax law,


 


in either case to the
effect that, and based thereon such opinion of counsel will confirm that, the holders of the outstanding Notes will not recognize
income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income
tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not
occurred;


 


(3)          in the case of an election under Section 8.03 hereof, the Issuers must deliver to the Trustee an opinion of counsel
reasonably acceptable to the Trustee confirming 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;


 


(4)         no
Default or Event of Default has occurred and is continuing on the date of such deposit (other than a Default or Event of Default
resulting from the incurrence of Indebtedness, the proceeds of which are applied to such deposit (and any similar concurrent deposit
relating to other Indebtedness), and the granting of Liens to secure such Indebtedness);


 


(5)         such
Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under, any material
agreement or instrument (other than this Indenture and the agreements governing any other Indebtedness being defeased, discharged
or replaced) to which the Parent or any of its Subsidiaries is a party or by which the Parent or any of its Subsidiaries is bound;


 


(6)          the Issuers must deliver to the Trustee an Officers’ Certificate stating that the deposit was not made by the
Issuers with the intent of preferring the Holders of Notes over the other creditors of the Issuers with the intent of defeating,
hindering, delaying or defrauding creditors of the Issuers or others; and


 


(7)          the
Issuers must deliver to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions
precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with.


 






    	 	75	 



     


    

 



 


Section 8.05         Deposited
Money and Government Securities to be Held in Trust; Other Miscellaneous Provisions.


 


Subject to Section
8.06 hereof, all money and non-callable Government Securities (including the proceeds thereof) deposited with the Trustee (or other
qualifying trustee, collectively for purposes of this Section 8.05, the “Trustee”) pursuant to Section 8.04
hereof in respect of the outstanding Notes will be held in trust and applied by the Trustee, in accordance with the provisions
of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Parent or any of its
Subsidiaries acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due
thereon in respect of principal, premium, if any, and interest, but such money need not be segregated from other funds except to
the extent required by law.


 


The Issuers will pay
and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or non-callable Government
Securities deposited pursuant to Section 8.04 hereof or the principal and interest received in respect thereof other than any such
tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes.


 


Notwithstanding anything
in this Article 8 to the contrary, the Trustee will deliver or pay to the Issuers from time to time upon the request of the Issuers
any money or non-callable Government Securities held by it as provided in Section 8.04 hereof which, in the opinion of a nationally
recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which
may be the opinion delivered under Section 8.04(1) hereof), are in excess of the amount thereof that would then be required to
be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.


 


Section 8.06         Repayment to Issuers.


 


Subject to applicable
escheat and abandoned property laws, any money deposited with the Trustee or any Paying Agent, or then held by the Issuers, in
trust for the payment of the principal of, premium on, if any, or interest, if any, on, any Note and remaining unclaimed for two
years after such principal, premium, if any, or interest has become due and payable shall be paid to the Issuers on their request
or (if then held by the Issuers) will be discharged from such trust; and the Holder of such Note will thereafter be permitted to
look only to the Issuers for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Issuers as trustee thereof, will thereupon cease; provided, however, that, if any Definitive
Notes are then outstanding, the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense
of the Issuers cause to be published once, in the New York Times and The Wall Street Journal (national edition),
notice that such money remains unclaimed and that, after a date specified therein, which will not be less than 30 days from the
date of such notification or publication, any unclaimed balance of such money then remaining will be repaid to the Issuers.


 


Section 8.07         Reinstatement.


 


If the Trustee or Paying
Agent is unable to apply any U.S. dollars or non-callable Government Securities in accordance with Section 8.02 or 8.03 hereof,
as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise
prohibiting such application, then the Issuers’ and the Guarantors’ obligations under this Indenture and the Notes
and the Note Guarantees will be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 hereof
until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.02 or 8.03 hereof,
as the case may be; provided, however, that, if the Issuers make any payment of principal of, premium on, if any, or interest
on any Note following the reinstatement of its obligations, the Issuers will be subrogated to the rights of the Holders of such
Notes to receive such payment from the money held by the Trustee or Paying Agent.

ARTICLE 9

AMENDMENT, SUPPLEMENT AND WAIVER


 


Section 9.01         Without Consent of Holders of Notes.


 


Notwithstanding Section
9.02 of this Indenture, without the consent of any Holder of Notes, the Issuers, the Guarantors and the Trustee may amend or supplement
this Indenture, the Notes or the Note Guarantees:


 


(1)                to
cure any ambiguity, defect or inconsistency;


 


(2)                to provide for uncertificated Notes in addition to or in place of certificated Notes;


 


(3)                to provide for the assumption of an Issuer’s or a Guarantor’s obligations to Holders of Notes in the
case of a merger or consolidation or sale of all or substantially all of such Issuer’s or Guarantor’s properties or
assets;


 


(4)                to
make any change that would provide any additional rights or benefits to the Holders of Notes or that does not adversely affect
the legal rights under this Indenture of any such Holder;


 


(5)                to secure the Notes or the Note Guarantees pursuant to the requirements of Section 4.12;


 


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


 


(7)                to add any additional Guarantor or to evidence the release of any Guarantor from its Note Guarantee, in each case
as provided in this Indenture;


 


(8)                to evidence or provide for the acceptance of appointment under this Indenture of a successor Trustee; or


 


(9)                to conform the text of this Indenture, the Note Guarantees or the Notes to any provision of the “Description
of Notes” in the Issuers’ offering memorandum, dated December 16, 2019.


 


Upon the request of
the Company, and upon receipt by the Trustee of the documents described in Section 9.06 hereof, the Trustee will join with the
Issuers and the Guarantors in the execution of any amended or supplemental indenture authorized or permitted by the terms of this
Section 9.01 and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee
will not be obligated to enter into such amended or supplemental indenture that affects its own rights, duties or immunities under
this Indenture or otherwise.


 


Section 9.02         With Consent of Holders of Notes.


 


Except as provided
below in this Section 9.02, the Issuers, the Guarantors and the Trustee may amend or supplement this Indenture (including, without
limitation, Sections 3.09, 4.10 and 4.15 hereof) and the Notes and the Note Guarantees with the consent of the Holders of a majority
in aggregate principal amount of the then outstanding Notes (including, without limitation, Additional Notes, if any) voting as
a single class (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase
of, the Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing Default or Event of Default (other than a Default or
Event of Default in the payment of the principal of, premium on, if any, or interest on, the Notes, except a payment default resulting
from an acceleration that has been rescinded) or compliance with any provision of this Indenture or the Notes or the Note Guarantees
may be waived with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes (including,
without limitation, Additional Notes, if any) voting as a single class (including, without limitation, consents obtained in connection
with a tender offer or exchange offer for, or purchase of, the Notes). (Section 2.08 hereof shall determine which Notes are considered
to be “outstanding” for purposes of this Section 9.02.) However, without the consent of each Holder affected, an amendment,
supplement or waiver under this Section 9.02 may not (with respect to any Notes held by a non-consenting Holder):


 






    77


     


    

 


(1)                reduce
the principal amount of Notes whose Holders must consent to an amendment, supplement or waiver;


 


(2)                reduce the principal of or change the fixed maturity of any Note or alter the provisions with respect to the redemption
or repurchase of the Notes (other than provisions under Sections 4.10 and 4.15);


 


(3)                reduce the rate of or change the time for payment of interest on any Note;


 


(4)                waive a Default or Event of Default in the payment of principal of, or interest or premium, if any, on the Notes
(except a rescission of acceleration of the Notes by the Holders of a majority in aggregate principal amount of the Notes and a
waiver of the payment default that resulted from such acceleration);


 


(5)                make any Note payable in currency other than that stated in the Notes;


 


(6)                make any change in the provisions of this Indenture relating to waivers of past Defaults or the rights of Holders
of Notes to receive payments of principal of, or interest or premium, if any, on the Notes (other than as permitted in clause (7)
below);


 


(7)                waive a redemption or repurchase payment with respect to any Note (other than a payment required by Section 4.10
or 4.15);


 


(8)               
release any Guarantor from any of its obligations under its Note Guarantee or this Indenture, except in accordance
with the terms of this Indenture; or


 


(9)                make any change in the preceding amendment, supplement and waiver provisions.


 


Upon the request of
the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental
indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes
as aforesaid, and upon receipt by the Trustee of the documents described in Section 9.06 hereof, the Trustee will join with the
Issuers and the Guarantors in the execution of such amended or supplemental indenture unless such amended or supplemental indenture
directly affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee
may in its discretion, but will not be obligated to, enter into such amended or supplemental indenture.


 


It is not necessary
for the consent of the Holders of Notes under this Section 9.02 to approve the particular form of any proposed amendment, supplement
or waiver, but it is sufficient if such consent approves the substance thereof.


 






    78


     


    

 


After an amendment,
supplement or waiver under this Section 9.02 becomes effective, the Company will send to the Holders of Notes affected thereby
a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to give such notice, or any defect
therein, will not, however, in any way impair or affect the validity of any such amended or supplemental indenture or waiver.


 


Section 9.03         [Reserved].


 


Section 9.04         Revocation and Effect of Consents.


 


Until an amendment,
supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of a Note and
every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even
if notation of the consent is not made on any Note. However, any such Holder of a Note or subsequent Holder of a Note may revoke
the consent as to its Note if the Trustee receives written notice of revocation before the date the amendment, supplement or waiver
becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every
Holder.


 


Section 9.05         Notation on or Exchange of Notes.


 


The Trustee may place
an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Issuers in exchange
for all Notes may issue and the Trustee shall, upon receipt of an Authentication Order, authenticate new Notes that reflect the
amendment, supplement or waiver.


 


Failure to make the
appropriate notation or issue a new Note will not affect the validity and effect of such amendment, supplement or waiver.


 


Section 9.06          Trustee to Sign Amendments, etc.


 


The Trustee will sign
any amended or supplemental indenture authorized pursuant to this Article 9 if the amendment or supplement does not adversely affect
the rights, duties, liabilities or immunities of the Trustee. In executing any amended or supplemental indenture, the Trustee will
be entitled to receive and (subject to Section 7.01 hereof) will be fully protected in relying upon, in addition to the documents
required by Sections 7.02(b) and 12.04 hereof, an Officers’ Certificate and an Opinion of Counsel stating that the execution
of such amended or supplemental indenture is authorized or permitted by this Indenture.


 


ARTICLE 10

NOTE GUARANTEES


 


Section 10.01        Guarantee.


 


(a)           Subject to this Article 10, each of the Guarantors hereby, jointly and severally, unconditionally Guarantees to each Holder
of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity
and enforceability of this Indenture, the Notes or the obligations of the Issuers hereunder or thereunder, that:


 


(1)                the principal of, premium on, if any, and interest on, the Notes will be promptly paid in full when due, whether
at stated maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of, premium on, if any, and
interest on, the Notes, if lawful, and all other obligations of the Company to the Holders or the Trustee hereunder or thereunder
will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and


 






    79


     


    

 


(2)               
in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that same will
be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at stated maturity,
by acceleration or otherwise.


 


Failing payment when
due of any amount so Guaranteed or any performance so Guaranteed for whatever reason, the Guarantors will be jointly and severally
obligated to pay the same immediately. Each Guarantor agrees that this is a Guarantee of payment and not a Guarantee of collection.


 


(b)           The Guarantors hereby agree that their obligations hereunder are unconditional, irrespective of the validity, regularity
or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder
of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Issuers, any action to
enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor.
Each Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency
or bankruptcy of the Issuers, any right to require a proceeding first against the Issuers, protest, notice and all demands whatsoever
and covenant that this Note Guarantee will not be discharged except by complete performance of the obligations contained in the
Notes and this Indenture.


 


(c)            If any Holder or the Trustee is required by any court or otherwise to return to the Issuers, the Guarantors or any custodian,
trustee, liquidator or other similar official acting in relation to either the Issuers or the Guarantors, any amount paid by any
of them to the Trustee or such Holder, this Note Guarantee, to the extent theretofore discharged, will be reinstated in full force
and effect.


 


(d)           Each Guarantor agrees that it will not be entitled to any right of subrogation in relation to the Holders in respect of
any obligations Guaranteed hereby until payment in full of all obligations Guaranteed hereby. Each Guarantor further agrees that,
as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (1) the maturity of the obligations
Guaranteed hereby may be accelerated as provided in Article 6 hereof for the purposes of this Note Guarantee, notwithstanding any
stay, injunction or other prohibition preventing such acceleration in respect of the obligations Guaranteed hereby, and (2) in
the event of any declaration of acceleration of such obligations as provided in Article 6 hereof, such obligations (whether or
not due and payable) will forthwith become due and payable by the Guarantors for the purpose of this Note Guarantee. The Guarantors
will have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the
rights of the Holders under the Note Guarantee.


 


Section 10.02         Limitation on Guarantor Liability.


 


Each Guarantor, and
by its acceptance of Notes, each Holder, hereby confirm that it is the intention of all such parties that the Note Guarantee of
such Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance
Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to any Note Guarantee. To
effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of
such Guarantor will be limited to the maximum amount that will, after giving effect to such maximum amount and all other contingent
and fixed liabilities of such Guarantor that are relevant under such laws, and after giving effect to any collections from, rights
to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other
Guarantor under this Article 10, result in the obligations of such Guarantor under its Note Guarantee not constituting a fraudulent
transfer or conveyance.


 






    80


     


    

 


Section 10.03         Execution and Delivery of Note Guarantee.


 


To evidence its Note
Guarantee set forth in Section 10.1 hereof, each Guarantor hereby agrees that a notation of such Note Guarantee substantially in
the form attached as Exhibit E hereto will be endorsed by an Officer of such Guarantor on each Note authenticated and delivered
by the Trustee and that this Indenture will be executed on behalf of such Guarantor by one of its Officers.


 


Each Guarantor hereby
agrees that its Note Guarantee set forth in Section 10.01 hereof will remain in full force and effect notwithstanding any failure
to endorse on each Note a notation of such Note Guarantee.


 


If an Officer whose
signature is on the notation of its Note Guarantee no longer holds that office at the time the Trustee authenticates the Note on
which such notation of its Note Guarantee is endorsed, the Note Guarantee will be valid nevertheless.


 


The delivery of any
Note by the Trustee, after the authentication thereof hereunder, will constitute due delivery of the Note Guarantee set forth in
this Indenture on behalf of the Guarantors.


 


Section 10.04         Guarantors May Consolidate, etc., on Certain Terms.


 


A Guarantor other than
the Parent may sell or otherwise dispose of all or substantially all of its properties or assets to, or consolidate with or merge
with or into (whether or not such Guarantor is the surviving Person) another Person, other than the Company or another Guarantor,
unless:


 


(1)           immediately after giving effect to such transaction, no Default or Event of Default exists; and


 


(2)           either:


 


 (A)             the Person acquiring the properties or assets in any such sale or disposition or the Person formed by or surviving any such
consolidation or merger (if other than the Guarantor) unconditionally assumes all the obligations of that Guarantor under, the
Notes, its Note Guarantee and this Indenture on the terms set forth herein, pursuant to a supplemental indenture in form reasonably
satisfactory to the Trustee; or


 


 (B)             such transaction does not violate Section 4.10 hereof.


 


In case of any such
consolidation, merger, sale or disposition and upon the assumption by the successor Person, by supplemental indenture, executed
and delivered to the Trustee and satisfactory in form to the Trustee, of the Note Guarantee of the Guarantor and the due and punctual
performance of all of the covenants and conditions of this Indenture to be performed by the Guarantor, such successor Person will
succeed to and be substituted for the Guarantor with the same effect as if it had been named herein as a Guarantor. Such successor
Person thereupon may cause to be signed any or all of the notations of Note Guarantees to be endorsed upon all of the Notes issuable
hereunder which theretofore shall not have been signed by the Issuers and delivered to the Trustee. All the Note Guarantees so
issued will in all respects have the same legal rank and benefit under this Indenture as the Note Guarantees theretofore and thereafter
issued in accordance with the terms of this Indenture as though all of such Note Guarantees had been issued at the date of the
execution hereof.


 


Except as set forth
in Articles 4 and 5 hereof, and notwithstanding clauses 2(a) and (b) above, nothing contained in this Indenture or in any of the
Notes will prevent any consolidation or merger of a Guarantor with or into the Company or another Guarantor, or will prevent any
sale or disposition of all or substantially all of the properties or assets of a Guarantor to the Company or another Guarantor.


 






    81


     


    

 


Section 10.05         Releases.


 


The Note Guarantee
of a Guarantor other than the Parent shall be released:


 


(a)           in
connection with any sale or other disposition of all or substantially all of the properties or assets of that Guarantor (including
by way of merger, consolidation) to a Person that is not (either before or after giving effect to such transaction) the Parent
or a Restricted Subsidiary of the Parent, if the sale or other disposition does not violate Section 4.10 hereof;


 


(b)           in
connection with any sale or other disposition of Capital Stock of that Guarantor to a Person that is not (either before or after
giving effect to such transaction) the Parent or a Restricted Subsidiary of the Parent, if the sale or other disposition does not
violate Section 4.10 hereof and such Guarantor ceases to be a Restricted Subsidiary of the Parent as a result of the sale or other
disposition;


 


(c)           upon
designation of such Guarantor as an Unrestricted Subsidiary in accordance with the terms of this Indenture;


 


(d)           upon
the liquidation or dissolution of such Guarantor provided no Default or Event of Default has occurred that is continuing;


 


(e)           at
such time as such Guarantor ceases to borrow under the Credit Agreement or Guarantee any indebtedness incurred thereunder or any
other Indebtedness (other than the Notes) of either of the Issuers or any Guarantor in excess of the De Minimis Guaranteed Amount;
or


 


(f)            upon
such Guarantor consolidating with, merging into or transferring all of its properties or assets to the Company or another Guarantor,
and as a result of, or in connection with, such transaction such Guarantor dissolving or otherwise ceasing to exist.


 


In addition, the Note
Guarantee of any Guarantor will be released upon Legal Defeasance or Covenant Defeasance in accordance with Article 8 hereof or
satisfaction and discharge of this Indenture in accordance with Article 11 hereof.


 


Any Guarantor not released
from its obligations under its Note Guarantee as provided in this Section 10.05 will remain liable for the full amount of principal
of, premium on, if any, and interest on, the Notes and for the other obligations of such Guarantor under this Indenture as provided
in this Article 10.


 


ARTICLE 11

SATISFACTION AND DISCHARGE


 


Section 11.01       Satisfaction and Discharge.


 


This Indenture will
be discharged and will cease to be of further effect as to all Notes issued hereunder (except as to surviving rights of registration
of transfer or exchange of the Notes and as otherwise specified in this Article 11), when:


 






    82


     


    

 


(1)           either:


 


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


 


 (B)              all Notes that have not been delivered to the Trustee for cancellation have become due and payable or will become due and
payable within one year by reason of the sending of a notice of redemption or otherwise and the Issuers or any Guarantor has irrevocably
deposited or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders, cash in U.S.
dollars, non-callable Government Securities, or a combination of cash in U.S. dollars and non-callable Government Securities, in
amounts as will be sufficient without consideration of any reinvestment of interest (which in the case of a deposit in whole or
in part of non-callable Government Securities will be evidenced by the opinion of a nationally recognized firm of independent public
as to the sufficiency of such deposit), to pay and discharge the entire indebtedness on the Notes not delivered to the Trustee
for cancellation for principal, premium, if any, and accrued interest to the date of fixed maturity or redemption (provided
that if such redemption is made as provided in Section 3.07(b), (x) the amount of cash in U.S. dollars, non-callable Government
Securities, or a combination thereof, that must be irrevocably deposited will be determined using an assumed Make Whole Premium
calculated as of the date of such deposit and (y) the depositor must irrevocably deposit or cause to be deposited additional money
in trust on the redemption date as necessary to pay the Make Whole Premium as determined by such date (any such amount, the “Applicable
Premium Deficit”) (it being understood that any satisfaction and discharge shall be subject to the condition subsequent that
such Applicable Premium Deficit is in fact paid); provided, that the Trustee shall have no liability whatsoever in the event that
such Applicable Premium Deficit is not in fact paid after any satisfaction and discharge of this Indenture and that any Applicable
Premium Deficit will be set forth in an Officers’ Certificate delivered to the Trustee simultaneously with the deposit of
such Applicable Premium Deficit that confirms that such Applicable Premium Deficit will be applied toward such redemption));


 


(2)           in respect of clause (1)(b) of this Section 11.01, no Event of Default has occurred and is continuing on the date
of the deposit (other than an Event of Default resulting from the borrowing of funds to be applied to such deposit and any similar
deposit relating to other Indebtedness and, in each case, the granting of Liens to secure such borrowings), and the deposit will
not result in a breach or violation of, or constitute a default under, any material agreement or instrument (other than this Indenture
and the agreements governing any other Indebtedness that is being defeased, discharged or replaced) to which the Parent or any
of its Subsidiaries is a party or by which the Parent or any of its Subsidiaries is bound (other than with respect to the borrowing
of funds to be applied concurrently to make the deposit required to effect such satisfaction and discharge and any similar concurrent
deposit relating to other Indebtedness, and in each case the granting of Liens to secure such borrowings);


 


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


 


(4)           the Issuers have delivered irrevocable instructions to the Trustee to apply the deposited money toward the payment
of the Notes at fixed maturity or the redemption date, as the case may be.


 






    83


     


    

 


In addition, the Issuers
must deliver an Officers’ Certificate stating that all conditions precedent to satisfaction and discharge have been satisfied
and an Opinion of Counsel stating that all such conditions precedent set forth in clauses (2) and (4) of this Section 11.01 have
been satisfied.


 


Notwithstanding the
satisfaction and discharge of this Indenture, if funds have been deposited with the Trustee pursuant to subclause (b) of clause
(1) of this Section 11.01, the obligation set forth in Section 11.01(1)(b)(y) and the provisions of Sections 11.02 and 8.06
hereof will survive. In addition, nothing in this Section 11.01 will be deemed to discharge those provisions of Section 7.07 hereof,
that, by their terms, survive the satisfaction and discharge of this Indenture.


 


Section 11.02      Application of Trust Money; Miscellaneous


 


Subject to the provisions
of Section 8.06 hereof, all money deposited with the Trustee pursuant to Section 11.01 hereof shall be held in trust and applied
by it, in accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through any Paying
Agent (including the Parent or any of its Subsidiaries acting as the Paying Agent) as the Trustee may determine, to the Persons
entitled thereto, of the principal, premium, if any, and interest for whose payment such money has been deposited with the Trustee;
but such money need not be segregated from other funds except to the extent required by law.


 


If the Trustee or Paying
Agent is unable to apply any money or Government Securities in accordance with Section 11.01 hereof by reason of any legal proceeding
or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such
application, the Issuers’ and any Guarantor’s obligations under this Indenture and the Notes shall be revived and reinstated
as though no deposit had occurred pursuant to Section 11.01 hereof; provided that if the Issuers have made any payment of
principal of, premium on, if any, or interest on, any Notes because of the reinstatement of their obligations, the Issuers shall
be subrogated to the rights of the Holders of such Notes to receive such payment from the money or Government Securities held by
the Trustee or Paying Agent.


 


The Issuers will pay
and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or non-callable Government
Securities deposited pursuant to Section 11.01 hereof or the principal and interest received in respect thereof other than any
such tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes.

[Insert the Global Note Legend, if applicable
pursuant to the provisions of the Indenture]


 


[Insert the Private Placement Legend,
if applicable pursuant to the provisions of the Indenture]


 


Capitalized terms used
herein have the meanings assigned to them in the Indenture referred to below unless otherwise indicated.


 


(1)               Interest.
Archrock Partners, L.P., a Delaware limited partnership (the “Company”), and Archrock Partners Finance Corp.,
a Delaware corporation ((“Finance Corp.” and together with the Company, the “Issuers”) jointly
and severally promise to pay or cause to be paid interest on the principal amount of this Note at 6.25% per annum from December
20, 2019 until maturity. The Issuers will pay interest semi-annually in arrears on April 1 and October 1 of each year, or
if any such day is not a Business Day, on the next succeeding Business Day (each, an “Interest Payment Date”).
Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid,
from the date of issuance; provided that, if there is no existing Default in the payment of interest, and if this Note
is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest
shall accrue from such next succeeding Interest Payment Date; provided further that the first Interest Payment Date shall
be October 1, 2020. The Issuers will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law)
on overdue principal and premium, if any, from time to time on demand at a rate that is 1% higher than the then applicable interest
rate on the Notes to the extent lawful; they will pay interest (including post-petition interest in any proceeding under any Bankruptcy
Law) on overdue installments of interest (without regard to any applicable grace period), from time to time on demand at the same
rate to the extent lawful.


 


Interest will
be computed on the basis of a 360-day year comprised of twelve 30-day months.


 


(2)               Method
of Payment. The Issuers will pay interest on the Notes (except defaulted interest) to the Persons who are registered
Holders of Notes at the close of business on the March 15 or September 15 next preceding the Interest Payment Date, even if such
Notes are canceled after such record date and on or before such Interest Payment Date, except as provided in Section 2.12 of the
Indenture with respect to defaulted interest. The Notes will be payable as to principal, premium, if any, and interest at the
office or agency of the Issuers maintained for such purpose within the City and State of New York, or, at the option of the Issuers,
payment of interest and may be made by check mailed to the Holders at their addresses set forth in the register of Holders; provided
that payment by wire transfer of immediately available funds to an account in the United States will be required with respect
to principal of, premium on, if any, and interest on, all Global Notes. If a Holder of at least $5.0 million principal amount
of certificated Notes has given wire transfer instructions to the Issuers or the Paying Agent, the Issuers will pay all principal,
interest and premium, if any, on that Holder’s Notes in accordance with those instructions to an account in the United States.
Such payments will be in such coin or currency of the United States of America as at the time of payment is legal tender for payment
of public and private debts.


 


(3)               Paying
Agent and Registrar. Initially, Wells Fargo Bank, National Association, the Trustee under the Indenture, will act as
Paying Agent and Registrar. The Issuers may change the Paying Agent or Registrar without prior notice to the Holders of the Notes.
The Parent or any of its Subsidiaries may act as Paying Agent or Registrar.


 



    		A-3	 



     


    




 


(4)               Indenture.
The Issuers have issued the Notes under an Indenture dated as of December 20, 2019 (the “Indenture”) among
the Issuers, the Guarantors and the Trustee. The Notes are subject to all terms stated in the Indenture and those made part of
the Indenture by reference to the TIA, and Holders are referred to the Indenture and such Act for a statement of such terms. To
the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture
shall govern and be controlling. The Notes are unsecured obligations of the Issuers. The Indenture does not limit the aggregate
principal amount of Notes that may be issued thereunder.


 


(5)               Optional
Redemption.


 


(A)         At
any time prior to April 1, 2023, the Issuers may on any one or more occasions redeem up to 35% of the aggregate principal amount
of the Notes issued under the Indenture, but in an amount not greater than the net cash proceeds of one or more Equity Offerings,
at a redemption price of 106.250% of the principal amount plus accrued and unpaid interest, if any, to the redemption date (subject
to the right of Holders on the relevant record date to receive interest due on an interest payment date that is on or prior to
the redemption date), provided that:


 


(1)       at
least 65% of the aggregate principal amount of the Notes originally issued under the Indenture remains outstanding immediately
after the occurrence of such redemption (excluding Notes held by the Parent and its Subsidiaries); and


 


(2)       the
redemption occurs within 180 days of the date of the closing of such Equity Offering.


 


(B)          At any time prior to April 1, 2023, the Issuers may on any one or more occasions redeem all or part of the Notes, at a redemption
price equal to the sum of:


 


(1)       the
principal amount thereof, plus


 


(2)       the
Make Whole Premium at the redemption date,


 


plus accrued
and unpaid interest, if any, to the redemption date (subject to the right of Holders on the relevant record date to receive interest
due on an interest payment date that is on or prior to the redemption date).


 


(C)          Except
pursuant to Section 3.07(a), (b) and (e) of the Indenture, the Notes will not be redeemable at the Issuers’ option prior
to April 1, 2023.


 


(D)          The Issuers may redeem all (but not a portion of) the Notes when permitted by, and pursuant to the conditions in, Section
4.15(d) of the Indenture.


 






    		A-4	 



     


    

 


(E)           On
and after April 1, 2023, the Issuers may on any one or more occasions redeem all or a part of the Notes, at the redemption prices
(expressed as percentages of principal amount) set forth below, plus accrued and unpaid interest, if any, on the Notes redeemed
to the applicable redemption date (subject to the right of Holders on the relevant record date to receive interest due on an interest
payment date that is on or prior to the redemption date), if redeemed during the twelve-month period beginning on April 1 of the
years indicated below:


 


	Year	 	Percentage	 
	2023	 	 	103.125	%
	2024	 	 	102.083	%
	2025	 	 	101.042	%
	2026 and thereafter	 	 	100.000	%



 


Unless the
Issuers default in the payment of the redemption price, interest will cease to accrue on the Notes or portions thereof called for
redemption on the applicable redemption date.


 


(6)               
Mandatory Redemption. The Issuers are not required to make mandatory
redemption or sinking fund payments with respect to the Notes.


 


(7)               
Repurchase at the Option of Holder.


 


(A)          If there is a Change of Control, the Company will be required to make an offer (a “Change of Control Offer”)
to each Holder to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of each Holder’s
Notes at a purchase price in cash equal to 101% of the aggregate principal amount of Notes repurchased, plus accrued and unpaid
interest, if any, on the Notes repurchased to the date of settlement (the “Change of Control Settlement Date”),
subject to the rights of Holders of Notes on the relevant record date to receive interest due on the relevant interest payment
date that is on or prior to the Change of Control Settlement Date set forth in Section 4.15 of the Indenture. Within 30 days
following any Change of Control, the Company will send a notice to each Holder and the Trustee setting forth the procedures governing
the Change of Control Offer as required by the Indenture.


 


(B)          On
the 361st day after the Asset Sale (or at the Company’s option, any earlier date), if the aggregate amount of Excess Proceeds
then exceeds $25.0 million, the Company will make an Asset Sale Offer to all Holders of Notes (with a copy to the Trustee), and
all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in
the Indenture with respect to offers to purchase, prepay or redeem with the proceeds of sales of assets, to purchase, prepay or
redeem, on a pro rata basis as specified in the Indenture, the maximum principal amount of Notes and such other pari passu
Indebtedness that may be purchased, prepaid or redeemed out of the Excess Proceeds. The offer price in any Asset Sale Offer
will be equal to 100% of the principal amount plus accrued and unpaid interest, if any, to the date of settlement, subject to
the right of Holders on the relevant record date to receive interest due on an interest payment date that is on or prior to the
date of settlement, and will be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the
Parent or any of its Restricted Subsidiaries may use those Excess Proceeds for any purpose not otherwise prohibited by the Indenture.
If the aggregate principal amount of Notes tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds allocated
to the purchase of Notes, the Trustee will select the Notes to be purchased on a pro rata basis (except that any Notes represented
by a Note in global form will be selected by such method as DTC may require). Upon completion of each Asset Sale Offer, the amount
of Excess Proceeds will be reset at zero. Holders of Definitive Notes that are the subject of an offer to purchase will receive
an Asset Sale Offer from the Company prior to any related purchase date and may elect to have such Notes purchased by completing
the form entitled “Option of Holder to Elect Purchase” attached to the Notes.


 






    		A-5	 



     


    

 


(8)               
Notice of Redemption. At least 30 days but not more than 60
days before a redemption date, a notice of redemption will be sent to each Holder whose Notes are to be redeemed at its registered
address, except that redemption notices may be sent more than 60 days prior to a redemption date if the notice is issued in connection
with a defeasance of the Notes or a satisfaction and discharge of the Indenture pursuant to Article 8 or 11 thereof. Notes and
portions of Notes selected will be in amounts of $2,000 or whole multiples of $1,000 in excess thereof; except that if all of the
Notes of a Holder are to be redeemed, the entire outstanding amount of Notes held by such Holder shall be redeemed.


 


(9)               
Denominations, Transfer, Exchange. The Notes are in registered
form in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. The transfer of Notes may be registered
and Notes may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things,
to furnish appropriate endorsements and transfer documents and the Issuers may require a Holder to pay any transfer tax or similar
governmental charge payable in connection therewith. The Issuers need not exchange or register the transfer of any Note or portion
of a Note selected for redemption, except for the unredeemed portion of any Note being redeemed in part. Also, the Issuers need
not exchange or register the transfer of any Notes for a period of 15 days before a selection of Notes to be redeemed or during
the period between a record date and the next succeeding Interest Payment Date.


 


(10)           
Persons Deemed Owners. The registered Holder of a Note may be
treated as the owner of it for all purposes. Only registered Holders have rights under the Indenture.


 


(11)           
Amendment, Supplement and Waiver. Subject to certain exceptions,
the Indenture, the Notes or the Note Guarantees may be amended or supplemented with the consent of the Holders of a majority in
aggregate principal amount of the then outstanding Notes including Additional Notes, if any, voting as a single class, and any
existing Default or Event of Default or compliance with any provision of the Indenture or the Notes or the Note Guarantees may
be waived with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes including Additional
Notes, if any, voting as a single class. Without the consent of any Holder of Notes, the Indenture, the Notes or the Note Guarantees
may be amended or supplemented to cure any ambiguity, defect or inconsistency; to provide for uncertificated Notes in addition
to or in place of certificated Notes; to provide for the assumption of an Issuer’s or a Guarantor’s obligations to
Holders of Notes in the case of a merger or consolidation or sale of all or substantially all of such Issuer’s or Guarantor’s
properties or assets; to make any change that would provide any additional rights or benefits to the Holders of Notes or that does
not adversely affect the legal rights under the Indenture of any such Holder; to secure the Notes or the Note Guarantees pursuant
to the requirements of Section 4.12 of the Indenture; to provide for the issuance of additional Notes in accordance with the limitations
set forth in the Indenture; to add any additional Guarantor or to evidence the release of any Guarantor from its Note Guarantee,
in each case as provided in the Indenture; to evidence or provide for the acceptance of appointment under the Indenture of a successor
trustee; or to conform the text of the Indenture, the Note Guarantees or the Notes to any provision of the “Description of
Notes” in the Issuers’ offering memorandum, dated December 16, 2019.


 






    		A-6	 



     


    

 


(12)           
Defaults and Remedies. Events of Default include: (i) default
for 30 days in the payment when due of interest on the Notes; (ii) default in the payment when due (at stated maturity, upon redemption
or otherwise) of the principal of, or premium on, if any, the Notes; (iii) failure by the Issuers or the Parent to comply with
the provisions of Section 4.10, 4.15 or 5.01 of the Indenture; (iv) failure by the Parent for 180 days after notice to the Company
by the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding voting as a single class
to comply with Section 4.03 of the Indenture; (v) failure by the Issuers or the Parent for 60 days after notice to the Company
by the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding voting as a single class
to comply with any of their respective other agreements in the Indenture; (vi) default under certain other agreements relating
to Indebtedness of the Parent or any of its Restricted Subsidiaries which default is a Payment Default or results in the acceleration
of such Indebtedness prior to its express maturity; (vii) failure by the Parent or any of its Restricted Subsidiaries to pay final
judgments entered by a court or courts of competent jurisdiction aggregating in excess of $50.0 million (to the extent not covered
by insurance by a reputable and creditworthy insurer as to which the insurer has not disclaimed coverage), which judgments are
not paid, discharged or stayed, for a period of 60 days; (viii) certain events of bankruptcy, insolvency or reorganization with
respect to the Issuers, the Parent or any of its Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted
Subsidiaries that, taken together, would constitute a Significant Subsidiary; and (ix) except as permitted by the Indenture, any
Note Guarantee is held in any judicial proceeding to be unenforceable or invalid or ceases for any reason to be in full force and
effect, or any Guarantor, or any Person acting on behalf of any Guarantor, denies or disaffirms its obligations under its Note
Guarantee. In the case of an Event of Default arising from certain events of bankruptcy, insolvency or reorganization with respect
to the Issuers, the Parent, any Restricted Subsidiary of the Parent that is a Significant Subsidiary or any group of Restricted
Subsidiaries of the Parent that, taken together, would constitute a Significant Subsidiary, all outstanding Notes will become due
and payable immediately without further action or notice. If any other Event of Default occurs and is continuing, the Trustee or
the Holders of at least 25% in aggregate principal amount of the then outstanding Notes may declare all the Notes to be due and
payable immediately. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. Subject to certain
limitations, Holders of a majority in aggregate principal amount of the then outstanding Notes may direct the time, method and
place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred
on it. The Trustee may withhold from Holders of the Notes notice of any continuing Default or Event of Default (except a Default
or Event of Default relating to the payment of principal, premium, if any, or interest), if it determines that withholding notice
is in their interest. The Holders of a majority in aggregate principal amount of the then outstanding Notes by notice to the Company
and the Trustee may, on behalf of all the Holders, rescind an acceleration or waive an existing Default or Event of Default and
its consequences under the Indenture except a continuing Default or Event of Default in the payment of principal of, premium on,
if any, or interest on, the Notes (including in connection with an offer to purchase any Notes). The Issuers are required to deliver
to the Trustee annually an Officers’ Certificate regarding compliance with the Indenture, and the Issuers are required, upon
becoming aware of any Default or Event of Default, to deliver to the Trustee a written statement specifying such Default or Event
of Default.


 


(13)           
Trustee Dealings with Company. The Trustee, in its individual or any
other capacity, may make loans to, accept deposits from, and perform services for the Company or its Affiliates, and may otherwise
deal with the Company or its Affiliates, as if it were not the Trustee.


 


(14)           
No Recourse Against Others. No director, officer, partner, employee,
incorporator, manager or unitholder or other owner of Capital Stock of the Issuers or any Guarantor, as such, will have any liability
for any obligations of the Issuers or the Guarantors under the Notes, the Indenture, the Note Guarantees or for any claim based
on, in respect of, or by reason of, such obligations or their creation. Each Holder of Notes by accepting a Note waives and releases
all such liability. The waiver and release are part of the consideration for issuance of the Notes.


 






    		A-7	 



     


    

 


(15)           
Authentication. This Note will not be valid until authenticated by
the manual signature of the Trustee or an authenticating agent.


 


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


 


(17)           
CUSIP Numbers. Pursuant to a recommendation promulgated by the Committee
on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Notes, and the Trustee
may use CUSIP numbers in notices of redemption as a convenience to Holders. No representation is made as to the accuracy of such
numbers either as printed on the Notes or as contained in any notice of redemption, and reliance may be placed only on the other
identification numbers placed thereon.


 


(18)           
GOVERNING LAW. THE LAW OF THE STATE OF NEW YORK WILL GOVERN
AND BE USED TO CONSTRUE THE INDENTURE, THIS NOTE AND THE NOTE GUARANTEES.
