Section 1.4           Financial Calculations for Limited Condition Transactions


 


When calculating the availability under any
basket or ratio under this Indenture, in each case in connection with a Limited Condition Transaction and other transactions in
connection therewith (including any incurrence or issuance of Indebtedness, Disqualified Stock or preferred stock and the use of
proceeds thereof), the date of determination of such basket or ratio and of any Default or Event of Default may, at the option

or basket shall be calculated on a Pro Forma Basis after giving effect to such Limited Condition Transaction and other transactions
in connection therewith (including any incurrence or issuance of Indebtedness, Disqualified Stock or preferred stock and the use
of proceeds thereof) as if they had been consummated at the beginning of the applicable period for purposes of determining the
ability to consummate any such Limited Condition Transaction; provided that if the Company elects to make such determination
as of the date of such definitive agreement(s), then (x) the Company shall be deemed to be in compliance with such ratios or baskets
solely for purposes of determining whether the Limited Condition Transaction and other transactions in connection therewith (including
any incurrence or issuance of Indebtedness, Disqualified Stock or preferred stock and the use of proceeds thereof), is permitted
under this Indenture, and (y) such ratios or baskets shall not be tested at the time of consummation of such Limited Condition
Transaction or related transactions; provided, further, that if the Company elects to have such determinations occur at
the time of entry into such definitive agreement(s), any such transactions (including any incurrence or issuance of Indebtedness,
Disqualified Stock or preferred stock and the use of proceeds thereof) shall be deemed to have occurred on the date the definitive
agreement(s) is entered into and shall be deemed outstanding thereafter for purposes of calculating any ratios or baskets under
this Indenture after the date of such definitive agreement(s) and before the consummation of such Limited Condition Transaction,
unless such definitive agreement(s) is terminated or such Limited Condition Transaction or incurrence or issuance of Indebtedness,
Disqualified Stock or preferred stock or such other transaction to which pro forma effect is being given does not occur. For
the avoidance of doubt, the Trustee shall have no liability or responsibility for any calculation under or in connection with this
Indenture.

to be bound thereby.  However, to the extent any provision of any Note conflicts with the express provisions of this Indenture,

to a successor of such Depository or a nominee of such successor.


 


Each Global Note shall represent such of the
outstanding Notes as shall be specified therein and each shall provide that it represents the aggregate principal amount of outstanding
Notes from time to time endorsed thereon and that the aggregate amount of outstanding Notes represented thereby may from time to
time be reduced or increased, as appropriate, to reflect exchanges and redemptions.  Any endorsement of a Global Note to reflect

The paying agent shall be entitled to make
any payment net of any taxes or other sums required by any applicable law to be withheld or deducted.

The Company shall require each paying agent
other than the Trustee to agree in writing that the paying agent will hold in trust, for the benefit of the Holders or the Trustee,
all money held by the paying agent for the payment of principal of or premium or interest on the Notes, and will notify the Trustee
of any default by the Company or the Subsidiary Guarantors in making any such payment.  While any such default continues,
the Trustee may require a paying agent to pay all money held by it to the Trustee.  The Company at any time may require a
paying agent to pay all money held by it to the Trustee.  Upon payment over to the Trustee, the paying agent (if other than
the Company or a Subsidiary) shall have no further liability for the money delivered to the Trustee.

order.


 


(a)            
No service charge shall be made to a Holder for any registration of transfer or exchange, but the Company may require payment
of a sum sufficient to cover any taxes, duties or governmental charge payable in connection therewith (other than any such taxes,
duties or governmental charge payable upon exchange or transfer pursuant to Sections 2.11, 4.17, 4.18 and 9.6 hereof).


 


(b)            
All Global Notes and Definitive Notes issued upon any registration of transfer or exchange of Global Notes or Definitive

period beginning at the opening of business 15 calendar days before any Redemption Date and ending at the close of business

The Trustee or the Authentication Agent shall authenticate Global Notes and Definitive Notes in accordance with the provisions
of Section 2.2 hereof.


 


Section 2.7          
Mutilated, Destroyed, Lost and Stolen Notes.


 


If any mutilated Note is surrendered to the
Trustee, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Note of like tenor
and principal amount and bearing a number not contemporaneously outstanding.


 


If there shall be delivered to the Company
and the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Note and (ii) such security
or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of
notice to the Company or the Trustee that such Note has been acquired by a bona fide purchaser, the Company shall execute and upon
its request the Trustee shall authenticate and make available for delivery, in lieu of any such destroyed, lost or stolen Note,
a new Note of like tenor and principal amount and bearing a number not contemporaneously outstanding.


 


In case any such mutilated, destroyed, lost
or stolen Note has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Note,
pay such Note.


 


Upon the issuance of any new Note under this
Section, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed
in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith.


 


Every new Note issued pursuant to this Section in
lieu of any destroyed, lost or stolen Note shall constitute an original additional contractual obligation of the Company, whether
or not the destroyed, lost or stolen Note shall be at any time enforceable by anyone, and shall be entitled to all the benefits
of this Indenture equally and proportionately with any and all other Notes duly issued hereunder.


 


The provisions of this Section are exclusive
and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated,
destroyed, lost or stolen Notes.


 


Section 2.8          
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 on a Global Note effected by the Trustee in accordance with the provisions hereof and those described in this Section as
not outstanding.


 


If a Note is replaced pursuant to Section 2.7,
it ceases to be outstanding until the Trustee receives proof satisfactory to it that the replaced Note is held by a bona fide purchaser.


 


If one or more paying agents (other than the
Company, a Subsidiary or an Affiliate of any thereof) hold on the maturity date or on any Redemption Date, money sufficient to
pay such Notes payable on that date, then on and after that date such Notes cease to be outstanding and interest on them ceases
to accrue.


 






    39


     


    

 


A Note does not cease to be outstanding because
the Company, a Subsidiary Guarantor or an Affiliate of the Company or a Subsidiary Guarantor holds the Note.


 


Section 2.9         
Treasury Notes.


 


In determining whether the Holders of the
required principal amount of Notes have concurred in any request, demand, authorization, direction, notice, consent or waiver,
Notes owned by the Company or an Affiliate shall be disregarded, except that for the purposes of determining whether the Trustee
shall be protected in conclusively relying on any such request, demand, authorization, direction, notice, consent or waiver, only
Notes that a Responsible Officer of the Trustee actually knows are so owned shall be so disregarded.  Notwithstanding the
foregoing, Notes that are to be acquired by the Company, any Subsidiary Guarantor, any Subsidiary of the Company or any Subsidiary
Guarantor or an Affiliate of the Company or any Subsidiary Guarantor pursuant to an exchange offer, tender offer or other agreement
shall not be deemed to be owned by the Company, such Subsidiary Guarantor, a Subsidiary of the Company or such Subsidiary Guarantor
or an Affiliate of the Company or such Subsidiary Guarantor until legal title to such Notes passes to the Company, such Subsidiary
Guarantor, such Subsidiary or such Affiliate, as the case may be.


 


Section 2.10        Temporary Notes.


 


Until definitive Notes are ready for delivery,
the Company may prepare and the Trustee shall authenticate temporary Notes upon a Company Order.  Temporary Notes shall be
substantially in the form of definitive Notes but may have variations that the Company considers appropriate for temporary Notes. 
Without unreasonable delay, the Company shall prepare and the Trustee or the Authentication Agent upon request shall authenticate
definitive Notes in exchange for temporary Notes.  Until so exchanged, temporary Notes shall have the same rights under this
Indenture as the definitive Notes.


 


Section 2.11        Cancellation.


 


The Company at any time may deliver Notes
to the Trustee for cancellation. The registrar or the paying agent shall forward to the Trustee any Notes surrendered to them for
registration of transfer, exchange or payment. The Trustee, or at the direction of the Trustee, the registrar or the paying agent
and no one else, shall cancel all Notes surrendered for transfer, exchange, payment, replacement or cancellation and shall dispose
of such canceled Notes (subject to the record retention requirement of the Exchange Act or other applicable law) in accordance
with the Trustee’s customary practice. The Company may not issue new Notes to replace Notes that it has paid or delivered
to the Trustee for cancellation.


 


Section 2.12        Defaulted Interest.


 


If the Company and the Subsidiary Guarantors
default in a payment of interest on the Notes, the Company or any such Subsidiary Guarantor (to the extent of its obligations under
its Note Guarantee) shall pay the defaulted interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted
interest, to the Persons who are Holders on a subsequent special record date, which date shall be at the earliest practicable date
but in all events at least five Business Days prior to the payment date, in each case at the rate provided for with respect to
the applicable Notes.


 






    40


     


    

 


The Company shall notify the Trustee and the
paying agent in writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment,
and at the same time the Company shall deposit with the paying agent an amount of money equal to the aggregate amount proposed
to be paid in respect of such defaulted interest or shall make arrangements as are satisfactory to the paying agent for such deposit
prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled
to such defaulted interest as provided in this Section 2.12. The Company shall fix or cause to be fixed each such special
record date and payment date, and shall, promptly thereafter, notify the Trustee and the paying agent of any such date. At least
15 days before the special record date, the Company (or the Depository in the name of and at the expense of the Company) shall
deliver to Holders a notice that states the special record date, the related payment date and the amount of such interest to be
paid. The Company and the Subsidiary Guarantors may pay defaulted interest in any other lawful manner.


 


Section 2.13         Record Date.


 


The Company may set a record date for purposes
of determining the identity of Holders entitled to vote or consent to any action by vote or consent authorized or permitted under
this Indenture.  Unless otherwise specified, if a record date is not set by the Company prior to such vote or, in the case
of any such consent, the first solicitation of a Holder made by any Person in respect of such action, the record date will be the
later of (x) 10 days prior to the date of such vote or the first solicitation of such consent, as the case may be, and (y) the
date of the most recent list of Holders furnished to the Trustee prior to such vote or solicitation. The Trustee shall not have
any responsibility for determining the record date for any such action by vote or consent by the Holders.  The record date
for purposes of determining the identity of Holders entitled to payments of interest shall be the immediately preceding March 1
for each interest payment date occurring on March 15 and the immediately preceding September 1 for each interest payment date occurring
on September 15.


 


Section 2.14         CUSIP Number and ISIN Number.


 


The Company in issuing the Notes may use a
“CUSIP” number and an “ISIN” number, and if so, such CUSIP number and ISIN number shall be included in
notices of redemption or purchase as a convenience to Holders; provided, however, that any such notice may state that no representation
is made as to the correctness or accuracy of the CUSIP number and ISIN number printed in the notice or on the Notes, and that reliance
may be placed only on the other identification numbers printed on the Notes.  The Company shall promptly notify the Trustee
and each paying agent of any change in the CUSIP number and ISIN number.


 


Section 2.15         Deposit of Moneys.


 


Prior to 11:00 a.m. (New York City time),
on each date on which interest is to be paid, the maturity date and each payment date relating to an Asset Sale Offer or a Change
of Control Offer, and on the Business Day immediately following any acceleration of the Notes pursuant to Section 6.2, the
Company shall deposit with the paying agent in immediately available funds in U.S. Dollars sufficient to make cash payments, if
any, due on such interest payment date, maturity date, or Business Day, as the case may be.  Subject to receipt of such funds
by such time, the paying agent shall remit such payment in a timely manner to the Holders on such interest payment date, maturity
date or Business Day, as the case may be, to the Persons and in the manner set forth in paragraph 2 of the Notes.


 






    41


     


    

 


Article III.


REDEMPTION


 


Section 3.1           Selection of Notes to Be Redeemed.


 


If less than all of the Notes are to be redeemed
at any time, the Trustee (or the registrar, as applicable) shall select the Notes to be redeemed among the applicable Holders on
a pro rata basis or by lot (or, in the case of Notes issued in global form based on a method that most nearly approximates
a pro rata selection as the Trustee deems fair and appropriate in accordance with the Depository guidelines) unless otherwise
required by law or applicable stock exchange or depositary requirements, provided that no Notes of $2,000 or less shall be redeemed
in part.  In the event of partial redemption by lot, the particular Notes to be redeemed shall be selected, unless otherwise
provided herein, not less than 10 nor more than 60 days prior to the redemption date by the Trustee from the outstanding Notes
not previously called for redemption.


 


The Trustee shall, promptly notify the Company
and the paying agent 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 shall be in amounts of $2,000 or whole
multiples of $1,000 to the extent above $2,000; except that if all of the Notes of a Holder are to be redeemed, the entire outstanding
amount of Notes held by such Holder, even if not a multiple of $1,000, 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. 
Any such redemption or notice may, at the Company’s discretion, be subject to one or more conditions precedent, and if so
conditioned, the redemption date for such Notes may be extended by the Company pending achievement of such condition precedent.


 


Section 3.2           Notice of Redemption.


 


Subject to the provisions of Section 3.8
with respect to any Asset Sale Offer, at least 10 days but not more than 60 days before a redemption date, the Company shall deliver
or cause to be delivered by first class mail (or delivered electronically in accordance with the procedures of the Depository)
a notice of redemption to the Depository and, if any Definitive Registered Notes are outstanding, each Holder, in each case, with
a copy to the Trustee.


 


The notice shall identify the Notes to be
redeemed (including the CUSIP number and ISIN number, if any) and shall state:


 






    42


     


    

 


(a)              the redemption date;


 


(b)             the redemption price (including accrued interest to, but excluding, the applicable redemption date);


 


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


 


(d)              to the extent any Notes are held as Definitive Notes, the name and address of the paying agent to which the Notes are to
be surrendered for redemption;


 


(e)              that Notes called for redemption must be surrendered to the paying agent to collect the redemption price;


 


(f)               that,
unless the Company defaults in the making of such redemption payment, interest on Notes called for redemption ceases to accrue
on and after the redemption date; and


 


(g)              any conditions to such redemption.


 


At the Company’s request, the Trustee
in cooperation with the Depository shall give the notice of redemption in the Company’s name and at its expense; provided
that the Company gives the Trustee written notice of such request at least 10 days prior to the date of the giving of such notice
(or such shorter notice as may be acceptable to the Trustee).


 


Section 3.3           Effect of Notice of Redemption.


 


Once notice of redemption is delivered as
provided in Section 3.2, Notes called for redemption become due and payable on the redemption date and at the redemption price. 
On and after the redemption date, unless the Company defaults in the payment of the redemption price, interest will cease to accrue
on the Notes called for redemption and all rights of Holders with respect to such Notes will terminate except for the right to
receive payment of the redemption price upon surrender for redemption.  Upon surrender to the Trustee, such Notes shall be
paid at the redemption price plus accrued interest to the redemption date.


 


A notice of redemption may, at the Company’s
discretion, be subject to one or more conditions precedent, including completion of an offering of Capital Stock or another corporate
transaction.  If the Company becomes aware that any condition precedent provided for in the notice of redemption delivered
pursuant to Section 3.2 will not be satisfied on the Redemption Date specified in such notice, the Company shall notify the
Trustee in writing prior to the close of business two (2) Business Days prior to such Redemption Date (or such shorter period
as may be reasonably acceptable to the Trustee) and direct the Trustee to deliver such notice to the Holders. Upon receipt of such
notice by the Holders, the notice of redemption shall be rescinded or delayed, and the redemption of the Notes shall be rescinded
or delayed as provided in such notice.


 






    43


     


    

 


Section 3.4           Deposit of Redemption Price.


 


Prior to 11:00 a.m. (New York City time)
on the redemption date, the Company shall deposit with the paying agent money sufficient to pay the redemption price of and accrued
interest, if any, on all Notes to be redeemed on that date.  If the Company complies with the provisions of the preceding
sentence, on and after the redemption date, interest shall cease to accrue on the Notes or the portions of Notes called for redemption,
whether or not such Notes are presented for payment.  If any Note called for redemption shall not be so paid upon surrender
for redemption because of the failure of the Company to comply with the first sentence of this 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 with respect to such Note.


 


Section 3.5           Notes Redeemed in Part.


 


Upon surrender of a Note that is redeemed
in part, the Trustee or the Authentication Agent shall authenticate for the Holder a new Note and the same maturity equal in principal
amount to the unredeemed portion of the Note surrendered.


 


Section 3.6           Optional Redemption.


 


Prior to September 15, 2024, the Notes shall
be subject to redemption at any time at the option of the Company, in whole or in part, upon not less than 10 nor more than 60 days’
notice, at the Make-Whole Price, plus accrued and unpaid interest to, but excluding, the applicable redemption date.  On and
after September 15, 2024, the Notes will be subject to redemption at any time at the option of the Company, in whole or in part,
upon not less than 10 nor more than 60 days’ notice, at the redemption price (expressed as percentages of principal
amount) set forth below, plus accrued and unpaid interest to, but excluding, the applicable redemption date, if redeemed during
the 12-month period beginning on September 15 of the years indicated below:


 


	Year	 	Notes
 Percentage	 
	2024	 	 	102.438	%
	2025	 	 	101.609	%
	2026	 	 	100.814	%
	2027 and thereafter	 	 	100.000	%



 


Notwithstanding the foregoing, at any time
prior to September 15, 2022, the Company may on any one or more occasions redeem up to 40% in aggregate principal amount of the
Notes at a redemption price of 104.875% of the principal amount thereof, plus, in each case, accrued and unpaid interest to, but
excluding, the applicable redemption date, with cash in an amount not greater than the net cash proceeds of one or more Qualified
Equity Offerings; provided that:


 






    44


     


    

 


(1)          at least 50% of the aggregate principal amount of Notes (excluding any Additional Notes) issued under this Indenture remains
outstanding immediately after the occurrence of such redemption (excluding Notes held by the Company or any of its Subsidiaries)
unless all Notes are redeemed substantially concurrently; and


 


(2)          the redemption occurs within six months of the date of the closing of any such Qualified Equity Offering.


 


Section 3.7           Mandatory Redemption.


 


The Company shall not be required to make
mandatory redemption payments or sinking fund payments with respect to the Notes.


 


Section 3.8           Asset Sale Offers.


 


In the event that the Company or any Restricted
Subsidiary shall commence an Asset Sale Offer pursuant to Section 4.16, it shall follow the procedures specified below:


 


The Asset Sale Offer shall remain open for
twenty (20) Business Days after the Commencement Date relating to such Asset Sale Offer, except to the extent required to
be extended by applicable law (as so extended, the “Offer Period”).  No later than one (1) Business Day after
the termination of the Offer Period (the “Purchase Date”), the Company or such Restricted Subsidiary shall purchase
the principal amount (the “Offer Amount”) of Notes required to be purchased in such Asset Sale Offer pursuant to Sections 3.1
and 4.16 or, if less than the Offer Amount has been tendered, all Notes tendered in response to the Asset Sale Offer.


 


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


 


On the Commencement Date of any Asset Sale
Offer, the Company or such Restricted Subsidiary shall deliver or cause to be delivered, by first class mail (or delivered electronically
in accordance with the Applicable Procedures), a notice to each of the Holders, with a copy to the Trustee.  Such notice,
which shall govern the terms of the Asset Sale Offer, shall contain all instructions and materials necessary to enable the Holders
to tender Notes pursuant to the Asset Sale Offer and shall state:


 


(1)          that the Asset Sale Offer is being made pursuant to this Section 3.8 and Section 4.16 and the length of time the
Asset Sale Offer shall remain open;


 


(2)          the Offer Amount, the purchase price and the Purchase Date;


 


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


 






    45


     


    

 


(4)          that, unless the Company or such Restricted Subsidiary defaults in the payment of the purchase price, any Note accepted
for payment pursuant to the Asset Sale Offer shall cease to accrue interest on and after the Purchase Date;


 


(5)          that Holders electing to have a Note purchased pursuant to any Asset Sale Offer shall be required to surrender the Note,
with the form entitled “Option of Holder to Elect Purchase” on the reverse of the Note completed, to the Company, such
Restricted Subsidiary, the Depository or a paying agent at the address specified in the notice prior to the close of business on
the Business Day preceding the Purchase Date;


 


(6)          that Holders shall be entitled to withdraw their election if the Company, such Restricted Subsidiary, the Depository or
a paying agent, as the case may be, receives, not later than the close of business on the Business Day preceding the termination
of the Offer Period, a 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 such Holder’s election to have the Note
purchased;


 


(7)          that, if the aggregate principal amount of Notes surrendered by Holders exceeds the Offer Amount, the Trustee shall select
the Notes to be purchased on a pro rata basis and in accordance with the Applicable Procedures (with such adjustments as
may be deemed to be appropriate by the Company or such Restricted Subsidiary so that only Notes in denominations of $2,000, or
integral multiples of $1,000 in excess thereof, shall be purchased); and


 


(8)          that Holders whose Notes were purchased only in part shall be issued new Notes
equal in principal amount to the unpurchased portion of the Notes surrendered.


 


On or before 11:00 a.m. (New York
City time) on the applicable Purchase Date, the Company or such Restricted Subsidiary shall irrevocably deposit with the Trustee
or paying agent in immediately available funds the aggregate purchase price with respect to a principal amount of Notes equal to
the Offer Amount, together with accrued interest thereon, to be held for payment in accordance with the terms of this Section 3.8. 
On such Purchase Date, the Company or such Restricted Subsidiary shall, to the extent lawful, (i) accept for payment, on a
pro rata basis to the extent applicable, an aggregate principal amount equal to the Offer Amount of Notes and other Pari
Passu Indebtedness (in accordance with the terms of Section 4.16) tendered pursuant to the Asset Sale Offer, or if less than
the Offer Amount has been tendered, all Notes and such other Pari Passu Indebtedness or portions thereof tendered, (ii) deliver
or cause the Depository or paying agent, as the case may be, to deliver to the Trustee Notes so accepted and (iii) deliver
to the Trustee an Officers’ Certificate stating that such Notes or portions thereof were accepted for payment by the Company
or such Restricted Subsidiary in accordance with the terms of this Section 3.8.  The Company, such Restricted Subsidiary,
the Depository or paying agent, as the case may be, shall promptly (but in any case not later than three (3) Business Days
after the Purchase Date) mail or deliver to each tendering Holder an amount equal to the purchase price with respect to the Notes
tendered by such Holder and accepted by the Company or such Restricted Subsidiary for purchase, and the Company shall promptly
issue a new Note, and the Trustee shall authenticate and mail or deliver such new Note, to such Holder, equal in principal amount
to any unpurchased portion of such Holder’s Notes surrendered.  Any Note not accepted in the Asset Sale Offer shall
be promptly mailed or delivered by the Company or such Restricted Subsidiary to the Holder thereof.


 






    46


     


    

 


The Asset Sale Offer shall be made by the
Company or a Restricted Subsidiary in compliance with all applicable laws, including, without limitation, Regulation 14E of
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, and all other applicable federal and state securities
laws.  To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 3.8,
the Company or such Restricted Subsidiary shall comply with the applicable securities laws and regulations and shall not be deemed
to have breached its obligations under Sections 3.8 or 4.16 by virtue of such conflict.


 


Each purchase pursuant to this Section 3.8
shall be made pursuant to the provisions of Sections 3.1 through 3.5 to the extent applicable.


 


In the event the amount of Net Proceeds to
be applied to an Asset Sale Offer would result in the purchase of a principal amount of Notes which is not evenly divisible by
$1,000, the Trustee or the paying agent shall promptly refund to the Company or such Restricted Subsidiary, upon receipt of written
direction, the portion of such Net Proceeds that is not necessary to purchase the immediately lesser principal amount of Notes
that is so divisible.


 


To the extent that the aggregate amount of
Notes and other Pari Passu Indebtedness tendered pursuant to an Asset Sale Offer is less than the Asset Sale Offer Amount, the
Company or any Restricted Subsidiary may use any remaining Asset Sale Offer Amount for general corporate purposes (including the
repurchase of Indebtedness contractually subordinated in right of payment to the Notes to the extent not otherwise prohibited under
this Indenture).  Upon completion of such offer to purchase, the Asset Sale Offer Amount shall be reset at zero.


 


Section 3.9           Offers to Purchase.


 


In connection with any Change of Control Offer
or Alternate Offer, if Holders of not less than 90% in aggregate principal amount of the outstanding Notes validly tender and do
not withdraw such Notes in such offer and the Company, or any other Person making a Change of Control Offer in lieu of the Company,
purchases all of the Notes validly tendered and not withdrawn by such Holders, the Company or such other Person will have the right
(in their sole discretion), upon not less than 10 nor more than 60 days’ prior notice, given not more than 10 days after
such purchase pursuant to the Change of Control Offer, to redeem all Notes that remain outstanding after such purchase at a redemption
price in cash equal to the price offered to each other Holder in such offer, plus accrued and unpaid interest, to, but not including,
the date of redemption, subject to the right of Holders of record on the relevant record date to receive interest due on the relevant
interest payment date.

premium, if any, and interest then due.


 


Section 4.2           Reports.

certified independent accountants; and

The Trustee shall have no liability or responsibility
for the filing, timeliness or content of any such reports, documents or information filed by the Company and delivery of such reports,
documents or information to the Trustee is for informational purposes only and receipt of such shall not constitute constructive
notice thereof or any information contained therein.


 


In addition, whether or not required by the
rules and regulations of the SEC, the Company will file a copy of all such information and reports with the SEC for public
availability (unless the SEC will not accept such a filing) and make such information available to investors who request it in
writing.  The Company will not take any action for the purpose of causing the SEC not to accept any such filings.  If,
notwithstanding the foregoing, the SEC will not accept the Company’s filings for any reason, the Company will post the reports
referred to in the preceding paragraphs on its website within the time periods that would apply if the Company were required to
file those reports with the SEC.  The Trustee shall have no liability or responsibility for the filing, content or timeliness
of any such report.


 


Notwithstanding the foregoing, if at any time
the Notes are Guaranteed by any direct or indirect parent company of the Company, the Company shall satisfy its obligations under
this covenant with respect to financial information relating to the Company by furnishing financial information relating to such
direct or indirect parent company; provided, however, that the same is accompanied by consolidating information that
explains in reasonable detail the differences between the information relating to such direct or indirect parent company and any
of its Subsidiaries other than the Company and its Subsidiaries, on the one hand, and the information relating to the Company,
the Subsidiary Guarantors and the other Subsidiaries of the Company on a standalone basis, on the other hand.

Section 4.4           Compliance Certificate.


 


The Company shall deliver to the Trustee,

obligations under this Indenture, and further stating, as to each such Officer signing such certificate, that to the best of his
knowledge the Company and its Subsidiaries 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 hereof (or, if
a Default or Event of Default shall have occurred, describing all such Defaults or Events of Default of which he may have knowledge).


 


The Company will, so long as any Notes are
outstanding, deliver to the Trustee, forthwith upon any Officer becoming aware of any Default or Event of Default, an Officers’
Certificate specifying such Default or Event of Default and what action the Company is taking or proposes to take with respect
thereto.


 


Section 4.5           Stay, Extension and Usury Laws.


 


Each of the Company and the Subsidiary 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,
which may affect the covenants or the performance of this Indenture or the Notes; and each of the Company and the Subsidiary Guarantors
(to the extent 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 4.6           Corporate Existence.


 


Subject to Article V and any covenants
included in this Indenture or in a supplemental indenture relating to the release of Subsidiary Guarantors or the consolidation,
merger or amalgamation of Restricted Subsidiaries, the Company and each of the Restricted Subsidiaries shall do or cause to be
done all things necessary to preserve and keep in full force and effect (i) its existence in accordance with the respective
organizational documents (as the same may be amended from time to time), and (ii) the rights (charter and statutory), licenses
and franchises of the Company and the Restricted Subsidiaries; provided, however, that the Company and the Restricted
Subsidiaries shall not be required to preserve any such right, license or franchise if an Officer of the Company shall determine
that the preservation thereof is no longer desirable in the conduct of the business of the Company, the Restricted Subsidiaries
and their Subsidiaries, taken as a whole, and that the loss thereof is not adverse in any material respect to the Holders.


 






    49


     


    

 


Section 4.7           Taxes.


 


The Company shall, and shall cause each of
its Subsidiaries to, pay prior to delinquency all material taxes, assessments and governmental levies, except (i) as contested

condition (financial or otherwise), operations, performance or properties of the Company and its Subsidiaries, taken as a whole.


 


Section 4.8           Maintenance of Office or Agency.


 


The Company shall maintain an office or agency
(which may be an office of the Trustee or an affiliate of the Trustee, registrar or co-registrar) where the Notes may be surrendered
for registration of transfer or for exchange and where notices and demands to or upon the Company in respect of such Notes and
this Indenture may be served.  The Company shall give prompt written notice to the Trustee of the location, and any change
in the location, of such office or agency.  If at any time the Company shall fail to maintain any such required office or
agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be
made or served at the Corporate Trust Office of the Trustee.


 


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


 


The Company hereby designates the Corporate
Trust Office of the Trustee as one such office or agency of the Company in accordance with Section 2.3.


 


Section 4.9           Restricted Payments. The Company shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly:


 


(1)          declare or pay any dividend or make any distribution on account of the Company’s Equity Interests (other than dividends
or distributions payable in Equity Interests of the Company (other than Disqualified Stock));


 


(2)          purchase, redeem or otherwise acquire or retire for value any Equity Interests of the Company;


 






    50


     


    

 












 


(3)          purchase, redeem or otherwise acquire or retire prior to the date that is one year prior to the scheduled maturity for value
any Indebtedness (excluding any intercompany Indebtedness between or among the Company and any of its Restricted Subsidiaries)
that is contractually subordinated in right of payment to the Notes or the Note Guarantees, except a payment of interest or principal
at the Stated Maturity thereof; or


 


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


 


unless, at the time of such Restricted Payment:


 


(i)              no
Default or Event of Default shall have occurred and be continuing or would occur as a consequence thereof;


 


(ii)             other
than in respect of Restricted Payments as defined in clause (4) of the definition thereof, the Company would, at the time of such
Restricted Payment, on a Pro Forma Basis, have been permitted to incur at least $1.00 of additional Indebtedness pursuant to the
test set forth in the first paragraph of Section 4.10; and


 


(iii)           
such Restricted Payment, together with the aggregate of all other Restricted Payments made by the Company and the Restricted
Subsidiaries after October 1, 1996 (excluding Restricted Payments permitted by clauses (2) through (11) of the next
succeeding paragraph and any Restricted Payments in respect of the defeasance, redemption, repurchase, retirement or other acquisition
or retirement for value of any Indebtedness prior to the date hereof that would have been contractually subordinated in right of
payment to the Notes) would be less than (a) the cumulative EBITDA of the Company, minus 1.75 times the cumulative Consolidated
Interest Expense of the Company, in each case for the period (taken as one accounting period) from June 30, 1996, to the end
of the Company’s most recently ended fiscal quarter for which internal financial statements are available at the time of
such Restricted Payment, plus (b) the aggregate net Equity Proceeds received by the Company from the issuance or sale since
October 1, 1996 of Equity Interests of the Company or of debt securities of the Company that have been converted into such
Equity Interests (other than Equity Interests or convertible debt securities sold to a Restricted Subsidiary and other than Disqualified
Stock or debt securities that have been converted into Disqualified Stock), plus (c) an amount equal to the net reduction in Investments
since October 1, 1996 (other than reductions in Permitted Investments) in any Person resulting from payments of interest on
Indebtedness, dividends, repayments of loans or advances, or other transfers of assets, in each case to the Company or any of its
Restricted Subsidiaries or from the net cash proceeds from the sale of any such Investment (except, in each case, to the extent
any such payment or proceeds have already been included in the calculation of cumulative EBITDA) or from redesignations of Unrestricted
Subsidiaries as Restricted Subsidiaries (valued in each case as provided in the definition of “Investments”) not to
exceed, in each case, the amount of Investments previously made by the Company and its Restricted Subsidiaries in such Person),
plus (d)  $2.0 million.


 






    51


     


    







 


The foregoing provisions will not prohibit:


 


(1)          the payment of any dividend or the consummation of any irrevocable repurchase, redemption, defeasance or other acquisition
or retirement within 60 days after the date of declaration of the dividend or giving of the notice of repurchase, redemption,
defeasance or other acquisition or retirement, as the case may be, if at the date of declaration or notice, the dividend or repurchase,
redemption, defeasance or other acquisition or retirement would have complied with the provisions of this Indenture;


 


(2)          the making of any Restricted Payment in exchange for, or with the net cash proceeds of, the substantially concurrent sale
(other than to a Restricted Subsidiary) of other Equity Interests of the Company (other than any Disqualified Stock); provided
that the amount of any such net cash proceeds that are utilized for any such Restricted Payment will not be considered to be net
Equity Proceeds for purposes of clause (iii)(b) of the first paragraph of this Section 4.9 or clause (9) of this paragraph
and will not be considered to be net cash proceeds from a Qualified Equity Offering for purposes of Section 3.6;


 


(3)          the defeasance, redemption, repurchase, retirement or other acquisition or retirement for value of Indebtedness that is
contractually subordinated in right of payment to the Notes or the Note Guarantees, as applicable (including all accrued interest
on the Indebtedness, all accrued and unpaid dividends on Disqualified Stock, and the amount of all penalties, fees, costs, expenses,
discounts and premiums incurred in connection therewith and any original issue discount or debt issuance costs with respect thereto),
in exchange for, or with the net cash proceeds of, the issuance and sale (other than to the Company or any Restricted Subsidiary)
of Refinancing Indebtedness not more than 90 days before or after such defeasance, redemption, repurchase, retirement or other
acquisition or retirement for value;


 


(4)          the repurchase of any Indebtedness contractually subordinated in right of payment to the Notes or the Note Guarantees, as
applicable, at a purchase price not greater than 101% of the principal amount of such Indebtedness in the event of a Change of
Control in accordance with provisions similar to the covenant set forth in Section 4.17, provided that prior to or contemporaneously
with such repurchase the Company has made the Change of Control Offer as provided in such covenant with respect to the Notes and
has repurchased all Notes validly tendered for payment in connection with such Change of Control Offer;


 


(5)          the purchase, redemption, or other acquisition or retirement of Indebtedness subordinated in right of payment to the Notes
or any Note Guarantee (including all accrued interest on the Indebtedness, all accrued and unpaid dividends on Disqualified Stock,
and the amount of all penalties, fees, costs, expenses, discounts and premiums incurred in connection therewith and any original
issue discount or debt issuance costs with respect thereto) (A) with any Excess Proceeds remaining after completion of an Asset
Sale Offer (assuming such Excess Proceeds were not reset at zero) or (B) at a purchase price not greater than 100% of the principal
amount of such Indebtedness, plus accrued and unpaid interest thereon in the event of Asset Sale, to the extent required by the
terms of such Indebtedness; provided that the Company shall have first complied with its obligations under Section 4.16;


 






    52


     


    

 


(6)          the repurchase of Equity Interests deemed to occur upon the exercise of stock options to the extent such Equity Interests
represent a portion of the exercise price of those stock options;





 





(7)          so long as no Default or Event of Default has occurred and is continuing, the declaration and payment of regularly scheduled
or accrued dividends to holders of any class or series of Disqualified Stock of the Company or any preferred stock of any Restricted
Subsidiary issued on or after the date hereof in accordance with the Leverage Ratio test described in Section 4.10;


 


(8)          payments of cash, dividends, distributions, advances or other Restricted Payments by the Company or any Restricted Subsidiary
to allow the payment of cash in lieu of the issuance of fractional shares upon (i) the exercise of options or warrants or
(ii) the conversion or exchange of Capital Stock of any such Person;


 


(9)          additional payments to current or former employees, officers, directors or consultants (or their respective transferees,
estates or beneficiaries) of the Company for repurchases of stock, stock options or other equity interests in an aggregate amount
up to $5.0 million in any year, with unused amounts in any year permitted to be carried over to succeeding fiscal years; provided,
further, that such amount in any year under this clause may be increased by an amount not to exceed:


 


(i)              the
net cash proceeds from the sale of Equity Interests (other than Disqualified Stock) of the Company and, to the extent contributed
to the Company, the net cash proceeds from the sale of Equity Interests of any parent of the Company, in each case, to any future,
current or former employees, officers, consultants or directors of the Company, any of its Subsidiaries, or any parent of the
Company that occurs after the Issue Date, to the extent the net cash proceeds from the sale of such Equity Interests have not
otherwise been applied to the payment of Restricted Payments by virtue of clauses (i)-(iii) of the first paragraph of this Section
4.9 or clause (2) of this paragraph; plus


 


(ii)            
the cash proceeds of key man life insurance policies received by the Company or its Restricted Subsidiaries (or by any parent
of the Company to the extent contributed to the Company) after the Issue Date; minus


 


(iii)           
the amount of any Restricted Payments previously made with the cash proceeds described in the foregoing sub-clauses (i)
and (ii) of this clause (9);


 


provided that the Company may elect to apply all or any
portion of the aggregate increase contemplated by sub-clauses (i) and (ii) above in any twelve-month period;


 


(10)        any
Restricted Payment so long as after giving effect thereto, the Senior Leverage Ratio would be less than 4.5 to 1.0; and


 






    53


     


    

 





(11)        so long as no Default or Event of Default has occurred and is continuing, other Restricted Payments in an aggregate amount
under this clause (11) since the date of this Indenture not to exceed the greater of (x) $275.0 million and (y) 25% of
Adjusted EBITDA (determined as of the date of any Restricted Payment pursuant to this clause (11)).


 


Notwithstanding the foregoing, the Company
may declare or pay any dividend or make any distribution on or in respect of shares of the Company’s Capital Stock to holders
of such Capital Stock, so long as (1) such dividend or distribution is intended to be part of a distribution of the Company’s
earnings and profits in connection with the Company’s conversion to a REIT or (2) the Company believes in good faith
that it qualifies as a “real estate investment trust” under Section 856 of the Code (or any successor provision)
and that the declaration or payment of such dividend or making of such distribution is necessary either (i) to maintain the
Company’s status as a REIT for any taxable year or (ii) to enable the Company to avoid payment of any tax for any taxable
year that could be avoided by reason of paying such dividend or making such distribution by the Company to its stockholders, with
such dividend to be paid or distribution to be made as and when determined by the Company, whether during or after the end of the
relevant taxable year.


 


If an Investment results in the making of
a Restricted Payment, the aggregate amount of all Restricted Payments deemed to have been made as calculated under the foregoing
provision shall be reduced by the amount of any net reduction in such Investment (resulting from the payment of interest or dividends,
loan repayment, transfer of assets or otherwise) to the extent such net reduction is not included in the Company’s EBITDA;
provided, however, that the total amount by which the aggregate amount of all Restricted Payments may be reduced
may not exceed the lesser of (a) the cash proceeds received by the Company and the Restricted Subsidiaries in connection with
such net reduction and (b) the initial amount of such Investment.  In addition, for the avoidance of doubt and to avoid
double counting, if an Investment results in the making of a Restricted Payment, then the subsequent assignment, contribution,
distribution or other transfer of such Investment by the Company or any Restricted Subsidiary to any Excluded Restricted Subsidiary
or Unrestricted Subsidiary shall not be considered a new Investment or Restricted Payment and shall not further reduce the amount
that would otherwise be available for Restricted Payments under clause (iii) of the first paragraph of this Section.


 


If the aggregate amount of all Restricted
Payments calculated under the foregoing provision includes an Investment in an Unrestricted Subsidiary or other Person that thereafter
becomes a Restricted Subsidiary, such Investment will no longer be counted as a Restricted Payment for purposes of calculating
the aggregate amount of Restricted Payments.


 


For purposes of determining compliance with
this covenant, in the event that a Restricted Payment or Investment (or a portion thereof) meets the criteria of more than one
of the categories described in the second paragraph of this Section 4.9, or is permitted pursuant to clause (i), (ii) or (iii)
of the first paragraph of this Section 4.9 or pursuant to the definition of “Permitted Investments,” the Company will
be entitled to divide or classify (or later divide, classify or reclassify in whole or in part in its sole discretion) such Restricted
Payment or Investment (or, in each case, portion thereof) in any manner that complies with this covenant.


 






    54


     


    

 





For the purpose of making any Restricted Payment
calculations under this Indenture:


 


(1)          Investments shall include the Fair Market Value of the net assets of any Restricted Subsidiary at the time such Restricted
Subsidiary is designated an Unrestricted Subsidiary and shall exclude the Fair Market Value of the net assets of any Unrestricted
Subsidiary that is designated as a Restricted Subsidiary and, for the avoidance of doubt, such inclusions and exclusions will not
be limited by the amount of any Investment or aggregate Investments;


 


(2)          any asset or property transferred to or from an Unrestricted Subsidiary shall be valued at Fair Market Value at the time
of such transfer; provided that, for the avoidance of doubt, the Fair Market Value (as so determined) of such asset or property
shall be subtracted from (in the case of a transfer to an Unrestricted Subsidiary) or added to (in the case of a transfer from
an Unrestricted Subsidiary) the calculation under clause (iii) of the first paragraph of this Section; and


 


(3)          the amount of any Restricted Payment, if other than cash, shall be determined by the Company, whose good faith determination
shall be conclusive.


 


The Company’s Board of Directors may
designate a Restricted Subsidiary as an Unrestricted Subsidiary in compliance with Section 4.15.  Upon such designation,
all outstanding Investments by the Company and the Restricted Subsidiaries (except to the extent repaid in cash) in the Subsidiary
so designated will be deemed to be Restricted Payments made at the time of such designation.  Such designation will only be
permitted if such Restricted Payment would be permitted at such time and if such Restricted Subsidiary otherwise meets the definition
of an Unrestricted Subsidiary.


 


Section 4.10         Incurrence
of Indebtedness and Issuance of Preferred Stock.


 


The Company shall not, and shall not permit
any Restricted Subsidiary to, directly or indirectly, create, incur, issue, assume, Guarantee or otherwise become directly or indirectly
liable with respect to (or, collectively, “incur”) any Indebtedness (including Acquired Debt) and the Company shall
not permit any Restricted Subsidiary to issue any shares of preferred stock; provided, however, that the Company
may incur Indebtedness and may permit a Restricted Subsidiary to incur Indebtedness or issue preferred stock if, at the time of
such incurrence or issuance and after giving effect thereto on a Pro Forma Basis (including a pro forma application of the net
proceeds therefrom), the Leverage Ratio would be less than 7.0 to 1.0.


 


The foregoing limitations shall not apply
to:


 


(1)          the incurrence by the Company or any Restricted Subsidiary of Indebtedness and letters of credit under Credit Facilities
in an aggregate principal amount at any one time outstanding under this clause (1) (with letters of credit being deemed
to have a principal amount equal to the maximum potential liability of the Company and the Restricted Subsidiaries thereunder)
not to exceed $3,260.0 million;


 






    55


     


    

 





(2)          the issuance of the Note Guarantees on the date hereof;


 


(3)          the incurrence by the Company and the Restricted Subsidiaries of the Existing Indebtedness;


 


(4)          the issuance of the Notes on the date hereof;


 


(5)          the incurrence by the Company and the Restricted Subsidiaries of Capital Lease Obligations, mortgage financings and/or Indebtedness
constituting purchase money obligations, including all Refinancing Indebtedness incurred with respect thereto, up to an aggregate
at any one time outstanding of the greater of (i) $250.0 million and (ii) 5.0% of Consolidated Total Assets as of
any date of incurrence;


 


(6)          the incurrence or issuance of Indebtedness or preferred stock between (i) the Company and the Restricted Subsidiaries
and (ii) the Restricted Subsidiaries;


 


(7)          the incurrence by the Company and the Restricted Subsidiaries of Hedging Obligations not for purposes of speculation;


 


(8)          the incurrence by the Company and the Restricted Subsidiaries in respect of performance bonds, bankers’ acceptances,
workers’ compensation claims, surety, bid, appeal or similar bonds, completion guarantees, payment obligations in connection
with self-insurance or similar obligations, and bank overdrafts (and letters of credit in respect thereof) in the ordinary course
of business;


 


(9)          the incurrence by the Company and the Restricted Subsidiaries of Indebtedness consisting of “earn-out” obligations,
Guarantees, indemnities or obligations in respect of purchase price adjustments in connection with the acquisition or disposition
of assets, including, without limitation, shares of Capital Stock;


 


(10)        the incurrence by the Company or any Restricted Subsidiary of Indebtedness arising from the honoring by a bank or other
financial institution of a check, draft or similar instrument inadvertently drawn against insufficient funds, so long as such Indebtedness
is covered within five (5) Business Days;


 


(11)        the Guarantee by the Company or any Subsidiary Guarantor of Indebtedness of the Company or a Restricted Subsidiary and the
Guarantee by any non-Guarantor Subsidiary of Indebtedness of another non-Guarantor Subsidiary, in each case, to the extent that
the Guaranteed Indebtedness was permitted to be incurred by another provision of this Section 4.10; provided that if
the Indebtedness being Guaranteed is contractually subordinated to the Notes or the Note Guarantees, as applicable, then the Guarantee
must be subordinated to the same extent as the Indebtedness Guaranteed;


 


(12)         the incurrence by the Company and the Restricted Subsidiaries of Refinancing Indebtedness issued in exchange for, or the
proceeds of which are used to repay redeem, defease, extend, refinance, renew, replace or refund, Indebtedness (other than
intercompany Indebtedness) referred to in clauses (2) through (5) above, this clause (12) or clause (13) below
or that was otherwise permitted to be incurred pursuant to the test set forth in the first paragraph of this Section 4.10;


 






    56


     


    

 





(13)        the incurrence by the Company or any Restricted Subsidiary of additional Indebtedness in an aggregate principal amount (or
accreted value, as applicable) at any time outstanding, including all permitted Refinancing Indebtedness incurred to renew, refund,
refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (13), not to exceed $50.0 million;


 


(14)        Acquired
Debt and any other Indebtedness incurred to finance a merger, consolidation or other acquisition; provided that on a Pro
Forma Basis, either (A) the Company’s Leverage Ratio would be equal to or less than the Company’s Leverage Ratio immediately
prior to such merger, consolidation or other acquisition or (B) the Company would have been able to incur at least $1.00 of additional
Indebtedness pursuant to the first paragraph of this Section 4.10;


 


(15)        Indebtedness the net proceeds of which have been deposited in escrow to finance the repayment or redemption of such Indebtedness
pursuant to customary escrow arrangements pending the release thereof;


 


(16)        Indebtedness that has been discharged;


 


(17)        Indebtedness deemed to exist pursuant to the terms of a Joint Venture agreement as a result of a failure of the Company
or a Restricted Subsidiary to make a required capital contribution therein; provided that the only recourse on such Indebtedness
is limited to the Company’s or such Restricted Subsidiary’s equity interests in the related Joint Venture;


 


(18)        (i) Indebtedness representing deferred compensation to employees of the Company or any of its Restricted Subsidiaries incurred
in the ordinary course of business, and (ii) Indebtedness consisting of obligations of the Company or any of its Restricted Subsidiaries
under deferred compensation or other similar arrangements incurred by such Person in connection with any Investment permitted under
Section 4.9; and


 


(19)        Indebtedness of the Company or any Restricted Subsidiary in an aggregate principal amount up to 100% of the Equity Proceeds
received by the Company after the Issue Date from the issue or sale of Equity Interests of the Company or cash contributed to the
capital of the Company (in each case, other than proceeds of Disqualified Stock or sales of Equity Interests to the Company or
any of its Subsidiaries) to the extent such Equity Proceeds have not been applied pursuant to clause (iii)(b) of the first paragraph
of Section 4.9, or clause (2) or clause (9) of the second paragraph of Section 4.9, to make Restricted Payments, and provided,
that any such Equity Proceeds shall be excluded for purposes of making Restricted Payments pursuant to any of clause (iii)(b) of
the first paragraph of Section 4.9, or clause (2) or clause (9) of the second paragraph of Section 4.9, to the extent the Company
or any Restricted Subsidiary incur Indebtedness in reliance thereon.


 


Notwithstanding the foregoing, Restricted
Subsidiaries that are non-Guarantor Subsidiaries will not be permitted to incur Indebtedness or issue preferred stock pursuant
to the first paragraph of this Section 4.10 or clause (13) above if, after giving effect to such incurrence or issuance,
the aggregate principal amount of Indebtedness of such Restricted Subsidiaries that are non-Guarantor Subsidiaries (excluding intercompany
Indebtedness between or among the Company and the Restricted Subsidiaries) outstanding pursuant to such first paragraph or such
clause, together with the aggregate liquidation preference of preferred stock issued by such Restricted Subsidiaries that are non-Guarantor
Subsidiaries (excluding intercompany preferred stock issued between or among the Company and the Restricted Subsidiaries) outstanding
pursuant to such provisions, would exceed the greater of (x) $1.25 billion and (y) 1.25x Adjusted EBITDA as of any date
of incurrence.


 






    57


     


    




 


The Company will not incur, and the Company
will not permit any Subsidiary Guarantor to incur, any Indebtedness that is contractually subordinated in right of payment to any
other Indebtedness of the Company or such Subsidiary Guarantor unless such Indebtedness is also contractually subordinated in right
of payment to the Notes and the applicable Note Guarantee on substantially identical terms; provided, however, that
no Indebtedness will be deemed to be contractually subordinated in right of payment to any other Indebtedness of the Company or
a Subsidiary Guarantor solely by virtue of being unsecured or by virtue of being secured on a junior priority basis.


 


For purposes of determining compliance with
this Section 4.10, for the avoidance of doubt, in the event that an item of Indebtedness meets the criteria of more than one
of the categories of permitted debt described in clauses (1) through (19) above, or is entitled to be incurred pursuant
to the first paragraph of this Section 4.10, the Company will be permitted to classify such item of Indebtedness on the date
of its incurrence, or later reclassify all or a portion of such item of Indebtedness, in any manner that complies with this Section 4.10. 
Indebtedness under the Credit Agreement outstanding on the date on which Notes are first issued and authenticated under this Indenture
will at all times be deemed to have been incurred on such date in reliance on the exception provided by clause (1) above. 
The accrual of interest or preferred stock dividends, 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, the reclassification of preferred stock
as Indebtedness due to a change in accounting principles, and the payment of dividends on preferred stock or Disqualified Stock
in the form of additional shares of the same class of preferred stock or Disqualified Stock will not be deemed to be an incurrence
of Indebtedness or an issuance of preferred stock or Disqualified Stock for purposes of this Section 4.10; provided,
in each such case, that the amount thereof is included in the Consolidated Interest Expense of the Company as accrued.


 


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 currency other than U.S. Dollars will be calculated based on the relevant currency exchange rate in effect on
the date such Indebtedness was incurred; provided that if such Indebtedness is incurred to extend, replace, refund, refinance,
renew or defease, or that is exchanged for, other Indebtedness denominated in a currency other than U.S. Dollars, and such extension,
replacement, refunding, refinancing, renewal, defeasance or exchange would cause the applicable U.S. Dollar-denominated restriction
to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such extension, replacement, refunding,
refinancing, renewal, defeasance or exchange, such U.S. Dollar-denominated 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
extended, replaced, refunded, refinanced, renewed, defeased or exchanged.  Notwithstanding any other provision of this Section 4.10,
the maximum amount of Indebtedness that the Company or any Restricted Subsidiary may incur pursuant to this Section 4.10 shall
not be deemed to be exceeded solely as a result of fluctuations in exchange rates or currency values.


 






    58


     


    

 


The amount of any Indebtedness outstanding
as of any date will be:


 


(1)          the accreted value of the Indebtedness, in the case of any Indebtedness issued with original issue discount;


 


(2)          the principal amount of the Indebtedness, in the case of any other Indebtedness; and


 


(3)          in respect of Indebtedness of another Person secured by a Lien on the assets of the specified Person, the lesser of:


 


(i)              the
Fair Market Value of such assets at the date of determination; and


 


(ii)             the
amount of the Indebtedness of the other Person.


 


In connection with the incurrence of (i) revolving
loan Indebtedness under this Section 4.10 or (ii) any commitment relating to the incurrence of Indebtedness under this Section
4.10 and (in respect of both (i) and (ii)) the granting of any Lien to secure any such Indebtedness, the Company or the applicable
Restricted Subsidiary may designate, such incurrence and the granting of any such Lien as having occurred on the date of first
incurrence of such revolving loan Indebtedness or commitment (such date, the “Deemed Date”), and any related
subsequent actual incurrence or granting of any such Lien therefor will be deemed for all purposes under this Indenture to have
been incurred or granted on such Deemed Date, including, without limitation, for purposes of calculating the Leverage Ratio and
usage of any other baskets or ratios under this Indenture (as applicable).


 


The amount of Indebtedness that may be incurred
pursuant to any provision of this Section 4.10 or secured pursuant to Section 4.11 (i) shall be deemed to include all amounts necessary
to renew, refund, redeem, refinance, replace, restructure, defease or discharge any such Indebtedness incurred and/or secured pursuant
to such provisions, including after giving effect to additional Indebtedness in an amount equal to the aggregate amount of fees,
premia, underwriting discounts and other costs and expenses incurred in connection with such renewal, refund, redemption, refinancing,
replacement, restructuring, defeasance or discharge; and (ii) in any case where such amounts are or may be based on Consolidated
Total Assets or Adjusted EBITDA (or any ratio of which Adjusted EBITDA is a component), shall not be deemed to be exceeded, with
respect to such incurrence or grant of Lien, due solely to the result of fluctuations in the amount of Consolidated Total Assets
or Adjusted EBITDA (and, for the avoidance of doubt, such Indebtedness and such Lien will be permitted to be refinanced or replaced
notwithstanding that, after giving effect to such refinancing or replacement, such excess will continue).


 






    59


     


    

 


Section 4.11         Liens.


 


Neither the Company nor any Restricted Subsidiary
may directly or indirectly create, incur, assume or suffer to exist any Lien securing Indebtedness (other than a Permitted Lien)
upon any property or assets now owned or hereafter acquired, or any income, profits or proceeds therefrom, or assign or otherwise
convey any right to receive income therefrom, unless (a) in the case of any Lien securing any Indebtedness that is contractually
subordinate to the Notes or any Note Guarantee, as applicable, the Notes or any such Note Guarantee are secured by a Lien on such
property, assets or proceeds that is senior in priority to such Lien and (b) in the case of any other Lien securing Indebtedness,
the Notes or the applicable Note Guarantee are equally and ratably secured with the obligation or liability secured by such Lien.


 


For purposes of determining compliance with
this Section 4.11, (i) a Lien securing an item of Indebtedness need not be permitted solely by reference to one category of Permitted
Liens (or any portion thereof) described in the definition of “Permitted Liens” or pursuant to the first paragraph
of Section 4.11 but may be permitted in part under any combination thereof and (ii) in the event that a Lien securing an item of
Indebtedness (or any portion thereof) meets the criteria of one or more of the categories of Permitted Liens (or any portion thereof)
described in the definition of “Permitted Liens” or pursuant to the first paragraph of this Section 4.11, the Company
may, in its sole discretion, classify or reclassify, or later divide, classify or reclassify (as if incurred or issued at such
later time), such Lien securing such item of Indebtedness (or any portion thereof) in any manner that complies with this Section
4.11 and at the time of incurrence, issuance, classification or reclassification will be entitled to only include the amount and
type of such Lien or such item of Indebtedness secured by such Lien (or any portion thereof) in one of the categories of Permitted
Liens (or any portion thereof) described in the definition of “Permitted Liens” or pursuant to the first paragraph
of this Section 4.11 and, in such event, such Lien securing such item of Indebtedness (or any portion thereof) will be treated
as being incurred, issued or existing pursuant to only such clause or clauses (or any portion thereof) or pursuant to the first
paragraph of this Section 4.11 without including such item (or portion thereof) when calculating the amount of Liens or Indebtedness
that may be incurred or issued pursuant to any other clause or paragraph (or portion thereof) at such time.


 


With respect to any revolving loan Indebtedness
or commitment relating to the incurrence of Indebtedness that is designated to be incurred on any date pursuant to the second to
last paragraph of Section 4.10, any Lien that does or that shall secure such Indebtedness may also be designated by the Company
or any Restricted Subsidiary to be incurred on such date and, in such event, any related subsequent actual incurrence of such Lien
shall be deemed for all purposes under this Indenture to be incurred on such prior date, including for purposes of calculating
usage of any “Permitted Lien.”


 


With respect to any Lien securing Indebtedness
that was permitted to secure such Indebtedness at the time of the incurrence of such Indebtedness, such Lien shall also be permitted
to secure any Increased Amount of such Indebtedness. The “Increased Amount” of any Indebtedness shall mean any
increase in the amount of such Indebtedness that is not deemed to be an incurrence of Indebtedness for purposes of Section 4.10.

Section 4.12         Dividend and Other Payment Restrictions Affecting Restricted Subsidiaries.


 


The Company shall not, and shall not permit
any Restricted Subsidiary to, directly or indirectly, create or otherwise cause or suffer to exist or become effective any encumbrance
or restriction on the ability of any Restricted Subsidiary to:


 


(1)          (i) pay dividends or make any other distributions to the Company or any Restricted Subsidiary (A) on its Capital
Stock or (B) with respect to any other interest or participation in, or measured by, its profits, or (ii) pay any Indebtedness
owed to the Company or any Restricted Subsidiary;


 


(2)          make loans or advances to the Company or any Restricted Subsidiary; or


 


(3)          transfer any of its properties or assets to the Company or any Restricted Subsidiary.


 


However, the preceding restrictions will not
apply to encumbrances or restrictions existing under or by reason of:


 


(1)          agreements governing Existing Indebtedness as in effect as of the date hereof, and any amendments, modifications, restatements,
renewals, increases, supplements, refundings, replacements or refinancings thereof; provided that such amendments, modifications,
restatements, renewals, increases, supplements, refundings, replacements or refinancings are no more restrictive in the aggregate
with respect to such dividend and other payment restrictions than those contained in the agreements governing Existing Indebtedness
as in effect on the date hereof;


 


(2)          the Credit Agreement as in effect as of the date hereof, and any amendments, modifications, restatements, renewals, increases,
supplements, refundings, replacements or refinancings thereof; provided that such amendments, modifications, restatements,
renewals, increases, supplements, refundings, replacements or refinancings are no more restrictive in the aggregate with respect
to such dividend and other payment restrictions than those contained in the Credit Agreement as in effect on the date hereof;


 


(3)          this Indenture and the Notes;


 


(4)          applicable law, including, for the avoidance of doubt, any applicable rule, regulation or order;


 


(5)          any instrument governing Indebtedness or Capital Stock of a Person acquired by the Company or any Restricted Subsidiary
as in effect at the time of such acquisition (except to the extent such Indebtedness was incurred in connection with or in contemplation
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 permitted by the terms of this Indenture to be incurred;


 






    61


     


    

 


(6)          customary non-assignment provisions in contracts, licenses or leases entered into in the ordinary course of business and
consistent with past practices;


 


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


 


(8)          restrictions on the transfer of property subject to mortgages, purchase money obligations or Capital Lease Obligations otherwise
permitted by clause (5) of Section 4.10;


 


(9)          permitted Refinancing Indebtedness, provided that the restrictions contained in the agreements governing such Refinancing
Indebtedness are no more restrictive in the aggregate than those contained in the agreements governing the Indebtedness being refinanced;


 


(10)        Liens permitted to be incurred under Section 4.11 that limit the right of the debtor to dispose of the assets subject
to such Liens;


 


(11)        provisions limiting the disposition or distribution of assets or property in joint venture agreements, asset sale agreements,
sale-leaseback agreements, stock sale agreements and other similar agreements (including agreements entered into in connection
with a Permitted Investment) entered into with the approval of the Company’s Board of Directors, which limitation is applicable
only to the assets that are the subject of such agreements;


 


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


 


(13)        agreements governing other Indebtedness permitted to be incurred under the provisions of Section 4.10 and any amendments,
restatements, modifications, renewals, supplements, refundings, replacements or refinancings of those agreements; provided that
the restrictions therein will not materially affect the Company’s ability to make anticipated principal or interest payments
on the Notes (as determined in good faith by senior management or the Board of Directors of the Company); and


 


(14)        any Lien or restriction on a Securitization Subsidiary that, in the good faith judgment of senior management or the Board
of Directors of the Company, is reasonably required in connection therewith; provided, however, that such restrictions only apply
to Securitization Subsidiaries.


 


Section 4.13         Transactions with Affiliates.


 


The Company shall not, and shall not permit
any Restricted Subsidiary to, sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any
property or assets from, or enter into any contract, agreement, understanding, loan, advance or Guarantee with, or for the benefit
of, any Affiliate (each of the foregoing, an “Affiliate Transaction”) involving aggregate payments or consideration
made by the Company or any Restricted Subsidiary in excess of $25.0 million, unless:


 






    62


     


    

 


 


(a)           such Affiliate Transaction is on terms that are no less favorable to the Company or such Restricted Subsidiary than those
that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with a non-Affiliated Person;
and


 


(b)           with respect to any Affiliate Transaction involving aggregate payments in excess of $200.0 million, the Company delivers
to the Trustee a resolution of the Company’s Board of Directors set forth in an Officers’ Certificate certifying that
such Affiliate Transaction complies with clause (1) above and such Affiliate Transaction is approved by a majority of
the disinterested members of the Company’s Board of Directors.


 


The following items shall not be deemed Affiliate
Transactions and therefore, will not be subject to the provisions of the prior paragraph:


 


(1)          any employment agreement, employee benefit plan, officer or director indemnification agreement or any similar arrangement
entered into by the Company or any Restricted Subsidiary in the ordinary course of business and payments thereto;


 


(2)          transactions between or among the Company and one or more Restricted Subsidiaries;


 


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


 


(4)          payment of reasonable and customary fees and reimbursements of expenses (pursuant to indemnity arrangements or otherwise)
of officers, directors, employees or consultants of the Company or any Restricted Subsidiary;


 


(5)          any issuance of Equity Interests (other than Disqualified Stock) of the Company to Affiliates of the Company;


 


(6)          Restricted Payments and Permitted Investments that do not violate the provisions of Section 4.9;


 


(7)          payments to an Affiliate in respect of the Notes or any other Indebtedness of the Company or any Restricted Subsidiary on
the same basis as concurrent payments made or offered to be made in respect thereof to non-Affiliates;


 


(8)          loans or advances to employees in the ordinary course of business not to exceed $1.0 million in the aggregate at any
one time outstanding;


 


(9)          any transaction effected as part of a Qualified Securitization Facility, or any transaction involving the transfer of Receivables
of the type specified in the definition of “Credit Facilities” and permitted under paragraph (1) of Section 4.10;


 






    63


     


    

 





(10)        any transfers by the Company or any Restricted Subsidiary to, and any lease entered into by the Company or any Restricted
Subsidiary with, a wholly owned Unrestricted Subsidiary in connection with a Sale and Leaseback Transaction permitted under this
Indenture;


 


(11)        transactions
with Joint Ventures and Subsidiaries thereof and Unrestricted Subsidiaries that are approved by a majority of the disinterested
members of the Company’s Board of Directors (or by the audit committee or any committee of the Board of Directors consisting
of disinterested members of the Board of Directors) (a director shall be disinterested if he or she has no interest in such Joint
Venture or Unrestricted Subsidiary other than through the Company and its Restricted Subsidiaries);


 


(12)        any transaction with respect to which the Company or any of its Restricted Subsidiaries obtains an opinion as to the fairness
to the Company or such Restricted Subsidiary, as applicable, of such Affiliate Transaction from a financial point of view issued
by an accounting, appraisal or investment banking firm of national standing;


 


(13)        transactions with a Person who is not an Affiliate immediately before the consummation of such transaction that becomes
an Affiliate as a result of such transaction;


 


(14)        any lease entered into between the Company or any Restricted Subsidiary, as lessee and any Affiliate of the Company, as
lessor, which is approved by the Board of Directors of the Company in good faith, or any lease entered into between the Company
or any Restricted Subsidiary, as lessee, and any Affiliate of the Company, as lessor, in the ordinary course of business;


 


(15)        intellectual property licenses in the ordinary course of business;


 


(16)        payments to and from, and transactions with, any Joint Ventures entered into in the ordinary course of business or consistent

(17)        the payment of reasonable out-of-pocket costs and expenses relating to registration rights and indemnities provided to stockholders
of the Company or any parent of the Company pursuant to a stockholders agreement or a registration rights agreement entered into
on or after the Issue Date in connection therewith or similar equity holder’s agreements or limited liability company agreements;
and


 


(18)        transactions between the Company or any Restricted Subsidiary and any Person, which is an Affiliate solely due to a director
or directors of such Person (or a parent company of such Person) also being a director of the Company; provided, however,
that any such director abstains from voting as a director of the Company on any matter involving such other Person.


 


Section 4.14         Additional Note Guarantees.


 


No Restricted Subsidiary (other than an Excluded
Restricted Subsidiary and, following the release or termination of all Guarantees by a Foreign Subsidiary Holdco of any Indebtedness
of the Company or its other Subsidiaries other than the Notes, such Foreign Subsidiary Holdco) may, after the date hereof, Guarantee
the payment of (a) any Indebtedness of the Company or any Subsidiary Guarantor under any Credit Facility or (b) any Indebtedness
of the Company or any Subsidiary Guarantor evidenced by bonds, notes or other debt securities in an aggregate principal amount
of $10.0 million or more, unless such Restricted Subsidiary shall also execute within 60 days following the date on which
such requirement arose a Note Guarantee and delivered an Opinion of Counsel and Officers’ Certificate to the Trustee with
respect thereto, in accordance with the terms of this Indenture.


 



    64


     


    







 


No Subsidiary Guarantor may consolidate or
merge with or into (whether or not such Subsidiary Guarantor is the surviving Person) another Person (other than the Company),
whether or not affiliated with such Subsidiary Guarantor unless:


 


(1)          subject to the provisions of the following paragraph, the Person formed by or surviving any such consolidation or merger
(if other than such Subsidiary Guarantor) assumes all the obligations of such Subsidiary Guarantor under its Note Guarantee pursuant
to a supplemental indenture in a form reasonably satisfactory to the Trustee; and


 


(2)          immediately after giving effect to such transaction, no Default or Event of Default exists.


 


The Note Guarantee of a Subsidiary Guarantor
will automatically be released:


 


(1)          in connection with any sale or other disposition of Capital Stock of that Subsidiary Guarantor by way of consolidation,
merger or otherwise to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted
Subsidiary, if the sale or other disposition does not violate Section 4.16 and the Subsidiary Guarantor ceases to be a Restricted
Subsidiary as a result of the sale or other disposition;


 


(2)          in connection with any sale or other disposition of all or substantially all of the assets of that Subsidiary Guarantor
by way of consolidation, merger or otherwise to a Person that is not (either before or after giving effect to such transaction)
the Company or a Restricted Subsidiary, if the sale or other disposition does not violate Section 4.16 and the Subsidiary
Guarantor ceases to be a Restricted Subsidiary as a result of the sale or other disposition;


 


(3)          if the Company designates any Restricted Subsidiary that is a Subsidiary Guarantor as an Unrestricted Subsidiary in accordance
with the terms of Section 4.15;


 


(4)          upon legal defeasance or covenant defeasance of this Indenture as provided below under Article VIII; or


 


(5)          for any Foreign Subsidiary Holdco, concurrently with the release or termination of all Guarantees by such Foreign Subsidiary
Holdco of any Indebtedness of the Company or its other Subsidiaries other than the Notes.


 






    65


     


    




 


Section 4.15         Designation of Unrestricted Subsidiaries.


 


The Company’s Board of Directors may
designate any Subsidiary (including any Restricted Subsidiary or any newly acquired or newly formed Subsidiary) to be an Unrestricted
Subsidiary so long as:


 


(1)          any Investment in such Subsidiary deemed to be made as a result of designating such Subsidiary an Unrestricted Subsidiary
will not violate the provisions of Section 4.9; and


 


(2)          neither the Company nor any Restricted Subsidiary has any obligation to subscribe for additional shares of Capital Stock
or other Equity Interests in such Subsidiary, or to maintain or preserve such Subsidiary’s financial condition or to cause
such Subsidiary to achieve certain levels of operating results other than as permitted under Section 4.9.


 


For the avoidance of doubt, the provisions
of this Section 4.15 shall not limit or restrict the ability of any Restricted Subsidiary to sell, transfer or otherwise dispose
of any properties or assets to any other Subsidiary, including any Unrestricted Subsidiary, to the extent such sale, transfer or
other disposition is permitted under Section 4.13 or Section 4.16.


 


The Company’s Board of Directors may
designate any Unrestricted Subsidiary as a Restricted Subsidiary; provided that such designation will be deemed to be an
incurrence of Indebtedness by a Restricted Subsidiary of any outstanding Indebtedness of such Unrestricted Subsidiary and such
designation will only be permitted if:


 


(1)          such Indebtedness is permitted under Section 4.10; and


 


(2)          no Default or Event of Default would occur as a result of such designation.


 


Section 4.16         Asset Sales.


 


The Company shall not, and shall not permit
any Restricted Subsidiary to:


 


(1)          sell, lease, convey or otherwise dispose of any assets (including by way of a Sale and Leaseback Transaction, but excluding
a Qualifying Sale and Leaseback Transaction) other than (a) the sale, lease or other transfer of real estate, products, inventory,
services or accounts receivable in the ordinary course of business and any sale or other disposition of damaged, worn-out or obsolete
assets in the ordinary course of business (including the abandonment or other disposition of intellectual property that is, in
the reasonable judgment of the Company, no longer economically practicable to maintain or useful in the conduct of the business
of the Company and the Restricted Subsidiaries taken as whole), (b) licenses and sublicenses by the Company or any Restricted
Subsidiary of software or intellectual property in the ordinary course of business, (c) any surrender or waiver of contract
rights or settlement, release, recovery on or surrender of contract, tort or other claims in the ordinary course of business, (d) the
granting of Liens not prohibited by Section 4.11 or (e) the sale or other disposition of cash or Cash Equivalents (provided
that the sale, lease, conveyance or other disposition of all or substantially all of the assets of the Company will be governed
by Sections 4.17 and/or 5.1 and not by the provisions of this Section 4.16); or





 






    66


     


    




 


(2)          issue or sell Equity Interests of any Restricted Subsidiary,


 


that, in the case of either clause (1) or
(2) above, whether in a single transaction or a series of related transactions:


 


(i)              has a Fair Market Value in excess of $10.0 million; or


 


(ii)             results
in Net Proceeds in excess of $10.0 million (each of the foregoing, an “Asset Sale”),


 


unless (x) the Company (or the Restricted
Subsidiary, as the case may be) receives consideration at the time of such Asset Sale at least equal to the Fair Market Value of
the assets sold or otherwise disposed of and (y) at least 75% of the consideration therefor received by the Company or such
Restricted Subsidiary in the Asset Sale and all other Asset Sales since the Issue Date on a cumulative basis is in the form of
(i) cash, (ii) Cash Equivalents, (iii) like-kind assets, (iv) other assets used in or useful in the Company’s
business or (v) Designated Non-Cash Consideration having an aggregate Fair Market Value, taken together with all other Designated
Non-Cash Consideration received pursuant to this clause (B)(y)(v) that is at the time outstanding, not to exceed the
greater of (i) $50.0 million and (ii) 1.0% of Consolidated Total Assets as of the date of such Asset Sale (in each
case as determined in good faith by the Company);


 


provided, however, that the amount of any liabilities
(as shown on the Company’s or such Restricted Subsidiary’s most recent balance sheet or in the notes thereto) of the
Company or such Restricted Subsidiary (other than liabilities that are by their terms subordinated to the Notes or any Note Guarantee)
that are assumed by the transferee of any such assets, and any notes, securities or other obligations received by the Company or
such Restricted Subsidiary from such transferee that are converted by the Company or such Restricted Subsidiary into cash (to the
extent of the cash received) or Cash Equivalents within 180 days of such Asset Sale, shall be deemed to be cash for purposes of
this provision; and provided, further, that the 75% limitation referred to in the foregoing clause (B)(y) shall
not apply to any Asset Sale in which the cash portion of the consideration received therefrom is equal to or greater than what
the after-tax proceeds would have been had such Asset Sale complied with the aforementioned 75% limitation.  For the avoidance
of doubt, a disposition that constitutes a Restricted Payment or Permitted Investment will be governed by the provisions of Section 4.9
and not by this Section 4.16.


 


A transfer of assets or issuance of Equity
Interests by the Company to a Restricted Subsidiary or by a Restricted Subsidiary to the Company or to another Restricted Subsidiary
will not be deemed to be an Asset Sale.


 


Within 365 days of any Asset Sale, the
Company or any Restricted Subsidiary may, at its option, apply an amount equal to the Net Proceeds from such Asset Sale either:


 


(1)          to repay (a) Indebtedness and other obligations that are secured by a Lien or (b) Indebtedness of a Restricted Subsidiary
other than a Guarantor;


 






    67


     


    




 


(2)          to an investment in another business or capital expenditure or to other long-term assets, in each case, in the same line
of business as the Company or any Restricted Subsidiary is then engaged or in businesses similar or reasonably related thereto;


 


(3)          (a) to repay, prepay, redeem or purchase the Notes or (b) to repay other Indebtedness of the Company or a Subsidiary Guarantor
that ranks pari passu in right of payment with the Notes or any Note Guarantee, as applicable (“Pari Passu Indebtedness”);
provided that, to the extent the Company elects to repay such Pari Passu Indebtedness, the Company shall also equally and
ratably, at its option, (i) redeem the Notes pursuant to the optional redemption provisions of this Indenture; (ii) offer to reduce
Indebtedness under the Notes by making an offer (in accordance with the procedures set forth in Section 3.8) to Holders at
an offer price in cash in an amount equal to 100% of the principal amount thereof, plus accrued and unpaid interest, if any, to
the date of purchase, in accordance with the procedures set forth in Section 3.8; or (iii) purchase the Notes through privately
negotiated transactions or open market purchases in a manner that complies with this Indenture and applicable securities law at
a purchase price of at least 100% of the principal amount thereof, plus the amount of accrued but unpaid interest thereon up to
the principal amount of Notes to be repurchased; and/or


 


(4)          a combination of the repayments and investments permitted by the foregoing clauses (1) through (3).


 


Notwithstanding the foregoing, if within 365 days
after the receipt of any Net Proceeds from an Asset Sale, the Company (or the Restricted Subsidiary, as the case may be) enters
into a binding written agreement irrevocably committing the Company or such Restricted Subsidiary to an application of funds of
the kind described in clause (2) above within 180 days of such contractual commitment (an “Acceptable Commitment”),
the Company or such Restricted Subsidiary shall be deemed not to be in violation of the preceding paragraph so long as such application
of funds is consummated within 545 days of the receipt of such Net Proceeds. In the event any Acceptable Commitment is later
cancelled or terminated for any reason before the Net Proceeds are applied in connection therewith, then such Net Proceeds shall
constitute Excess Proceeds (defined below) unless the Company or such Restricted Subsidiary enters into another Acceptable Commitment
within 180 days of such cancellation or termination (a “Second Commitment”) and such Net Proceeds are actually
applied in such manner within 180 days from the date of the Second Commitment; provided, further, that if any Second Commitment
is later cancelled or terminated for any reason before such Net Proceeds are applied, then such Net Proceeds shall constitute Excess
Proceeds to the extent 720 days have elapsed since the date of receipt of such Net Proceeds by the Company or a Restricted Subsidiary.


 


Pending the final application of any such
Net Proceeds, the Company or any Restricted Subsidiary may temporarily reduce revolving credit Indebtedness or otherwise invest
such Net Proceeds in any manner that is not prohibited by this Indenture.  On the 365th day after an Asset Sale or such
earlier date, if any, as the Board of Directors of the Company or such Restricted Subsidiary determines not to apply the Net Proceeds
relating to such Asset Sale as set forth in clauses (1) through (4) of the second preceding paragraph (an “Asset
Sale Offer Trigger Date”), such aggregate amount of Net Proceeds (rounded down to the nearest $1,000) that has not been applied
on or before such Asset Sale Offer Trigger Date as permitted in clauses (1) through (4) of the second preceding
paragraph or the last provision of this paragraph (an “Asset Sale Offer Amount”) shall be applied by the Company or
such Restricted Subsidiary to make an offer to purchase (an “Asset Sale Offer”) to all Holders and, to the extent required
by the terms of any Pari Passu Indebtedness, to all holders of Pari Passu Indebtedness, on a date (such date, an “Asset Sale
Offer Payment Date”) not less than 30 nor more than 60 days following the applicable Asset Sale Offer Trigger Date,
from all Holders (and holders of any such Pari Passu Indebtedness) on a pro rata basis, the maximum amount of Notes and
Pari Passu Indebtedness equal to the Asset Sale Offer Amount at a price equal to 100% of the principal amount of the Notes and
Pari Passu Indebtedness to be purchased, plus accrued and unpaid interest thereon, if any, to the date of purchase.  The Company
and the Restricted Subsidiaries shall comply with the requirements of Regulation 14E as described under Section 3.8;
provided, however, the Company and the Restricted Subsidiaries may defer an Asset Sale Offer until there is an aggregate
unutilized Asset Sale Offer Amount equal to or in excess of $25.0 million resulting from one or more Asset Sales (at which
time, the entire unutilized Asset Sale Offer Amount, and not just the amount in excess of $25.0 million, shall be applied
as required pursuant to this Section 4.16 and Section 3.8). Upon completion of an Asset Sale Offer (including payment
for accepted Notes), any surplus Excess Proceeds that were the subject of such offer shall cease to be Excess Proceeds and the
amount of Excess Proceeds shall be reset to zero.

Section 4.17         Change of Control Offer.


 


(a)           Upon the occurrence of a Change of Control, each Holder shall have the right to require the Company to repurchase all or
any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of such Holder’s Notes pursuant to the offer
described below (the “Change of Control Offer”) at an offer price in cash equal to 101% of the aggregate principal
amount thereof, plus accrued and unpaid interest to, but excluding, the date of repurchase (the “Change of Control Payment”).
In connection with any Change of Control Offer, the Company may, in its sole discretion, elect to offer a premium (the “Early
Tender Premium”) to holders of Notes who tender their notes early in connection with such Change of Control Offer; provided
that the minimum payment offered to any holder of the Notes is no lower than 101% of the aggregate principal amount of Notes repurchased
plus accrued and unpaid interest on the Notes repurchased, to, but excluding, the date of purchase. In addition, the Company may
determine, in its sole discretion, to require as a condition to the receipt of such Early Tender Premium that holders (i) provide
consents to any requested amendments of this Indenture and (ii) waive any withdrawal rights in connection with the Change of Control
Offer.


 


Within 30 calendar days following any
Change of Control, the Company shall deliver a notice to each Holder stating:


 


(1)          that the Change of Control Offer is being made pursuant to this Section 4.17 and that all Notes tendered shall be accepted
for payment;


 


(2)          the purchase price and the purchase date, which shall be no earlier than 15 calendar days and no later than 60 calendar
days from the date such notice is delivered (the “Change of Control Payment Date”);


 


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


 






    69


     


    

 


(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 shall cease to accrue interest on and after the Change of Control Payment Date;


 


(5)          that Holders electing to have any Notes purchased pursuant to a Change of Control Offer shall be required to surrender such
Notes, with the form entitled “Option of Holder to Elect Purchase” on the reverse of the Notes completed, to the paying
agent at the address specified in such notice prior to the close of business on the fifth Business Day preceding the Change of
Control Payment Date;


 


(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 Change of Control Payment Date, 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 such 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 or an integral multiple of $1,000 in excess
thereof.


 


The Company shall comply with the requirements
of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder, to the extent such laws and
regulations are applicable to the repurchase of the Notes in connection with a Change of Control.  To the extent that the
provisions of any securities laws or regulations conflict with this Section 4.17, the Company shall comply with the applicable
securities laws and regulations and shall not be deemed to have breached its obligations under the Change of Control provisions
of this Indenture by virtue of such conflict.


 


(b)           On the Change of Control Payment Date, the Company shall, to the extent lawful:


 


(1)          accept for payment Notes or portions thereof tendered pursuant to the Change of Control Offer;


 


(2)          deposit with the paying agent an amount equal to the Change of Control Payment in respect of all Notes or portions thereof
so tendered; and


 


(3)          deliver or cause to be delivered to the Trustee or the paying agent the Notes so accepted together with an Officers’
Certificate stating the Notes or portions thereof tendered to the Company.


 


The paying agent shall promptly deliver to
each Holder so accepted the Change of Control Payment for such Notes, and the Trustee or the Authentication Agent shall promptly
authenticate, subject to the provisions hereof, and deliver to each such Holder a new Note equal in principal amount to any unpurchased
portion of the Notes surrendered, if any; provided that each such new Note shall be in a principal amount of $2,000 or an
integral multiple of $1,000 in excess thereof.


 






    70


     


    

 


The Company shall not be required to make
a Change of Control Offer upon a Change of Control if (i) a third party makes the Change of Control Offer in the manner, at the
times and otherwise in compliance with the requirements set forth in this Section 4.17 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; (ii) in connection
with or in contemplation of any Change of Control, the Company or any third party has made an offer to purchase (an “Alternate
Offer”) any and all Notes validly tendered at a cash price equal to or higher than the Change of Control Payment price and
has purchased all Notes validly tendered and not withdrawn under such Alternate Offer; or (iii) a notice of redemption of all outstanding
Notes has been given pursuant to Section 3.6, unless and until there is a default in payment of the applicable redemption price. 
Notwithstanding anything to the contrary contained herein, a Change of Control Offer 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.


 


Section 4.18         Changes in Covenants When Notes Are Rated Investment Grade.


 


If on any date following the date hereof:

(ii)             the Notes are rated BBB- or better by S&P, or


 


(iii)           
the Notes are rated BBB- or better by Fitch,


 


(or, if any such entity ceases to rate the
Notes for reasons outside of the control of the Company, the equivalent investment grade credit rating from any other “nationally
recognized statistical rating organization” registered under Section 15E of the Exchange Act selected by the Company
as a replacement agency); and


 


(2)          no Default or Event of Default shall have occurred and be continuing,


 


then, beginning on that date and continuing at all times thereafter
regardless of any subsequent changes in the rating of the Notes, (i) Sections 3.8, 4.9, 4.10, 4.12, 4.13, 4.14, 4.15 and 4.16
and clause (4) of Section 5.1 shall no longer be applicable as to the Notes and the Note Guarantees and (ii) for

(1)          either (i) the Company is the surviving entity or (ii) the Person formed by or surviving any such consolidation

under the Notes and this Indenture (pursuant to a supplemental indenture in a form satisfactory to the Trustee);


 


(3)          immediately after such transaction no Default or Event of Default exists; and


 


(4)          either (i) the Company or any Person formed by or surviving any such consolidation or merger, or to which such sale,
assignment, transfer, lease, conveyance or other disposition shall have been made, will, at the time of such transaction and on

the successor entity formed by such consolidation or into or with which the Company is merged or to which such sale, lease, conveyance
or other disposition is made (the “Successor Person”) shall succeed to, and be substituted for (so that from and after
the date of such consolidation, merger, sale, lease, conveyance or other disposition, the provisions of this Indenture referring
to the “Company” shall refer instead to the Successor Person and not to the Company) and may exercise every right and
power of the Company under this Indenture with the same effect as if such Successor Person has been named as the Company herein;
provided, however, that the predecessor Company in the case of a sale, lease, conveyance or other disposition shall
not be released from the obligation to pay the principal of and interest, if any, on the Notes, except in the case of a sale of

receivership, winding-up, liquidation, reorganization or relief of debtors or any amendment to, succession to or change in any
such law.  The term “Custodian” means any receiver, trustee, assignee, liquidator or similar official under any
Bankruptcy Law.


 


Section 6.2           Acceleration of Maturity.


 


In the case of an Event of Default under Section 6.1(g) or
(h) with respect to the Company, any Restricted Subsidiary that is a Significant Subsidiary or any group of Restricted Subsidiaries
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 (subject to Section 6.15), the Trustee
or 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.


 


Section 6.3           Collection
of Indebtedness and Suits for Enforcement by Trustee.


 


The Company covenants that if


 






    74


     


    

 


(a)           default
is made in the payment of any interest on any Note when such interest becomes due and payable and such default continues for a
period of 30 days, or


 


(b)           default is made in the payment of principal of any Note at the maturity thereof.


 


THEN, the Company will, upon demand of the Trustee, pay to it,
for the benefit of the Holders of such Notes, the whole amount then due and payable on such Notes for principal and interest and,
to the extent that payment of such interest shall be legally enforceable, interest on any overdue principal or any overdue interest,
at the rate or rates prescribed therefor in such Notes, and, in addition thereto, 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.


 


If the Company fails to pay such amounts forthwith
upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the
collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against
the Company or any other obligor upon such Notes and collect the moneys adjudged or deemed to be payable in the manner provided
by law out of the property of the Company or any other obligor upon such Notes, wherever situated.


 


If an Event of Default occurs and is continuing,
the Trustee may proceed to protect and enforce its rights and the rights of the Holders by such appropriate judicial proceedings
as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant
or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy.


 


Section 6.4           Trustee May File Proofs of Claim.


 


In case of the pendency of any receivership,
insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative
to the Company or any other obligor upon the Notes or the property of the Company or of such other obligor or their creditors,
but excluding any solvent reorganization or arrangement of capital pursuant to applicable corporations legislation, the Trustee
(irrespective of whether the principal of the Notes shall then be due and payable as therein expressed or by declaration or otherwise
and irrespective of whether the Trustee shall have made any demand on the Company for the payment of overdue principal or interest)
shall be entitled and empowered, by intervention in such proceeding or otherwise,


 


(a)           to
file and prove a claim for the whole amount of principal and interest owing and unpaid in respect of the Notes and to file such
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 of the Holders allowed
in such judicial proceeding,


 






    75


     


    

 


(b)           to
collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same, and


 


(c)           any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official 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 it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee hereunder.


 


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 thereof or to authorize the Trustee to vote in respect
of the claim of any Holder in any such proceeding.


 


Section 6.5           Trustee May Enforce Claims Without Possession of Notes.


 


All rights of action and claims under this
Indenture or the Notes may be prosecuted and enforced by the Trustee without the possession of any of the Notes or the production
thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name
as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of Holders in respect of
which such judgment has been recovered.


 


Section 6.6           Application of Money Collected.


 


Any money collected by the Trustee pursuant
to this Article shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution
of such money on account of principal or interest, upon presentation of the Notes and the notation thereon of the payment if only
partially paid and upon surrender thereof if fully paid:


 


First:  To the payment of all amounts
due the Trustee (acting in any capacity hereunder);


 


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


 


Third:  To the Company.


 


Section 6.7           Limitation on Suits.


 


Except to enforce the right to receive payment
of principal, premium, if any, or interest, if any, when due, no Holder shall have any right to institute any proceeding, judicial
or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder,
unless:






    76


     


    

 





(a)           such
Holder has previously given written notice to the Trustee of a continuing Event of Default;


 


(b)           Holders of at least 25% in aggregate principal amount of the then outstanding Notes shall have made written request to the
Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder;


 


(c)           such
Holder or Holders offer and, if requested, provide to the Trustee security or indemnity satisfactory to it against the costs,
expenses and liabilities to be incurred in compliance with such request;


 


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


 


(e)           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 written request;


 


it being understood and intended that no one or more of such
Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect,
disturb or prejudice the rights of any other of such Holders, or to obtain or to seek to obtain priority or preference over any
other of such Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and
ratable benefit of all such Holders.


 


Section 6.8           Unconditional Right of Holders to Receive Principal and Interest.


 


Subject to Article XII, notwithstanding
any other provision in this Indenture, the Holder of any Note shall have the right, which is absolute and unconditional, to receive
payment of the principal of and premium and interest, if any, on such Note on the Stated Maturity or Stated Maturities expressed
in such Note (or, in the case of redemption, on the redemption date) and to institute suit for the enforcement of any such payment,
and such rights shall not be impaired without the consent of such Holder.


 


Section 6.9           Restoration of Rights and Remedies.


 


If the Trustee or any Holder has instituted
any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any
reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination
in such proceeding, the Company, the Subsidiary Guarantors, the Trustee and the Holders shall be restored severally and respectively
to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though
no such proceeding had been instituted.


 


Section 6.10         Rights and Remedies Cumulative.


 


Except as otherwise provided with respect
to the replacement or payment of mutilated, destroyed, lost or stolen Notes in Section 2.7, no right or remedy herein conferred
upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and
remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise.  The assertion or employment of any right or remedy hereunder,
or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.


 









    77


     


    




 





Section 6.11         Delay or Omission Not Waiver.


 


No delay or omission of the Trustee or of
any Holder to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute
a waiver of any such Event of Default or an acquiescence therein.  Every right and remedy given by this Article or by
law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee
or by the Holders, as the case may be.


 


Section 6.12         Control by Holders.


 


The Holders of a majority in principal amount
of the outstanding Notes shall have the right to 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 the Trustee, provided that:


 


(a)           such
direction shall not be in conflict with any rule of law or with this Indenture,


 


(b)           the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction, and


 


(c)           subject
to the provisions of Section 6.1, the Trustee shall have the right to decline to follow any such direction if the Trustee
in good faith shall determine that the proceeding so directed would reasonably be expected to expose the Trustee to personal liability.


 


Section 6.13         Waiver of Past Defaults.


 


The Holders of a majority in aggregate principal
amount of the then outstanding Notes by written notice to the Trustee may, on behalf of all Holders, rescind an acceleration or
waive any existing Default or Event of Default and its consequences under this Indenture, if the rescission would not conflict
with any judgment or decree, except a continuing Default or Event of Default in the payment of principal of, premium on, if any,
or interest on, the Notes.  Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom
shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other
Event of Default or impair any right consequent thereon.


 


Section 6.14         Undertaking for Costs.


 


All parties to this Indenture agree, and each
Holder by his acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for
the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken, suffered
or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and
that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and expenses, against
any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant;
but the provisions of this Section shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder,
or group of Holders, holding in the aggregate more than 10% in principal amount of the outstanding Notes, or to any suit instituted
by any Holder for the enforcement of the payment of the principal of or interest on any Note on or after the Stated Maturity or
Stated Maturities expressed in such Note (or, in the case of redemption, on the redemption date).


 






    78


     


    

 


 


Section 6.15         Reporting
Defaults.


 


Notwithstanding Section 6.2, except as provided
in the second to last sentence of this paragraph, the sole remedy for any failure to comply by the Company with Section 4.2 shall
be the payment of liquidated damages as described in the following sentence, such failure to comply shall not constitute an Event
of Default, and Holders shall not have any right to accelerate the maturity of the Notes as a result of any such failure to comply.
If a failure to comply by the Company with Section 4.2 is continuing on the day that is 60 days following the Company’s receipt
of notice of such failure to comply in accordance with Section 6.1(d) (such notice, the “Reports Default Notice”),
the Company will pay liquidated damages to all Holders at a rate per annum equal to 0.25% of the principal amount of the Notes
then outstanding from such date to, but not including, the earlier of (x) the 121st day following the Company’s receipt of
the Reports Default Notice and (y) the date on which the failure to comply by the Company with Section 4.2 shall have been cured
or waived. On the earlier of the dates specified in the immediately preceding clauses (x) and (y), such liquidated damages will
cease to accrue. If the failure to comply by the Company with Section 4.2 shall not have been cured or waived on or before the
121st day following the Company’s receipt of the Reports Default Notice, then the failure to comply by the Company with Section
4.2 shall on such 121st day constitute an Event of Default. A failure to comply with Section 4.2 automatically shall cease to be
continuing and shall be deemed cured at such time as the Company furnishes to the Trustee the applicable information or report;
provided, however, that the Trustee shall have no obligation whatsoever to determine whether or not such information,
documents or reports have been filed pursuant to the EDGAR service (or its successor) nor shall the Trustee have any liability
or responsibility for the content of such reports. 


 


Article VII.

TRUSTEE


 


Section 7.1           Duties of Trustee.


 


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


 


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

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 Officers’ Certificates or Opinions of Counsel furnished to the Trustee and conforming
to the requirements of this Indenture; however, in the case of any such Officers’ Certificates or Opinions of Counsel which
by any provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall examine such Officers’
Certificates and Opinions of Counsel to determine whether or not they conform to the requirements of this Indenture (but need
not confirm or investigate the accuracy of mathematical calculations or other facts stated therein).

Trustee may not be relieved from liability for its own negligent action, its own negligent failure to act or its own willful misconduct,

Trustee shall not be liable with respect to any action taken, suffered or omitted to be taken by it with respect to the Notes
in good faith in accordance with the direction of the Holders of a majority in principal amount of the outstanding Notes relating
to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or
power conferred upon the Trustee, under this Indenture with respect to the Notes;


 


(d)           Every
provision of this Indenture that in any way relates to the Trustee is subject to paragraph (a), (b) and (c) of

(g)           No provision of this Indenture shall require the Trustee to risk its own funds or otherwise incur any financial liability
in the performance of any of its duties, or in the exercise of any of its rights or powers, if it shall have reasonable grounds
for believing that repayment of such funds or adequate indemnity against such risk is not reasonably assured to it;


 






    80


     


    

 


(h)           No
bond or surety shall be required with respect to performance of the Trustee’s duties and powers; and


 


(i)            The
paying agent, the registrar and the Authentication Agent shall be entitled to the protections, immunities and standard of care
as are set forth in paragraphs (b), (c), (e), (f), (g) and (h) of this Section with respect to the Trustee.


 


Section 7.2           Rights of Trustee.


 


(a)           The Trustee may conclusively rely on and shall be protected in acting or refraining from acting 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. 
The Trustee shall 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.


 


(c)           The
Trustee may act through agents and shall not be responsible for the misconduct or negligence of any agent appointed with due care. 
No Depository shall be deemed an agent of the Trustee and the Trustee shall not be responsible for any act or omission by any
Depository.  The Trustee shall also have no liability or responsibility for the action or inaction of DTC.

or within its rights or powers.


 


(e)           The
Trustee may consult with counsel of its selection and the advice of such counsel or any Opinion of Counsel shall be full and complete
authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance
thereon.


 


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


 


(g)           The
Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness
or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts
or matters as it may see fit and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled
to examine the books, records and premises of the Company, personally or by agent or attorney at the sole cost of the Company
and shall incur no liability or additional liability of any kind by reason of such inquiry or investigation.


 






    81


     


    

 


(h)           The
Trustee shall not be deemed to have notice of any Default or Event of Default (other than a payment default under Sections 6.1(a) or
6.1(b)) unless a Responsible Officer of the Trustee has received written notice of any event which is in fact such a default in
accordance with Section 11.1.


 


(i)            The
Trustee may request that the Company 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
be signed by any Person authorized to sign an Officers’ Certificate, including any Person specified as so authorized in
any such certificate previously delivered and not superseded.


 


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


 


(k)           In
no event shall the Trustee be responsible or liable for special, punitive, indirect, or consequential loss or damage of any kind
whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood
of such loss or damage and regardless of the form of action.


 


(l)            For certain payments made pursuant to this Indenture, the paying agent may be required to make a “reportable payment”
or “withholdable payment” and in such cases the paying agent may have the duty to act as a payor or withholding agent,
respectively, that is responsible for any tax withholding and reporting required under Chapters 3, 4, 24 and 61 of the Code. 
The paying agent shall have the sole right to make the determination as to which payments with respect to which it is the withholding
agent are “reportable payments” or “withholdable payments” under the Code.  All parties to this Indenture
shall provide an executed IRS Form W-9 or appropriate IRS Form W-8 (or, in each case, any successor form) to the paying
agent prior to closing, and shall promptly update any such form to the extent such form becomes obsolete or inaccurate in any respect. 
The paying agent shall have the right to request from any party to this Indenture, or any other Person entitled to payment hereunder,
any additional forms, documentation or other information as may be reasonably necessary for the paying agent to satisfy its reporting
and withholding obligations under the Code.  To the extent any such forms to be delivered under this Section 7.2(l) are
not provided prior to or by the time the related payment is required to be made or are determined by the paying agent to be incomplete
and/or inaccurate in any respect, the paying agent shall be entitled to withhold on any such payments hereunder to the extent withholding
is required under Chapters 3, 4, 24 or 61 of the Code, and shall have no obligation to gross up any such payment.


 






    82


     


    

 


Section 7.3           Individual Rights of Trustee.


 


The Trustee in its individual or any other
capacity may become the owner or pledgee of Notes and may otherwise deal with the Company or any of its Affiliates with the same
rights it would have if it were not Trustee.  However, if the Trustee acquires any conflicting interest it must eliminate
such conflict within 90 days or resign.  Any Agent may do the same with like rights.  The Trustee is also subject to
Section 7.9.  Under no circumstances shall the Trustee be liable in its individual capacity for the obligations evidenced
by the Notes.


 


Section 7.4           Trustee’s Disclaimer.


 


The Trustee makes no representation as to
the validity or adequacy of this Indenture or the Notes, it shall not be accountable for the Company’s use of the proceeds
from the Notes, and it shall not be responsible for any statement in the Notes other than its authentication.


 


Section 7.5           Notice of Defaults.


 


If a Default or Event of Default occurs and
is continuing with respect to the Notes and if it is actually known to a Responsible Officer of the Trustee as described in Section 7.2(h),
the Trustee shall mail to each Holder notice of a Default or Event of Default within 90 days after it occurs or, if later,
after a Responsible Officer of the Trustee has actual knowledge of such Default or Event of Default.  The Trustee may withhold
the notice if and so long as it in good faith determines that withholding the notice is in the interests of Holders, except a Default
or Event of Default relating to the payment of principal of, premium on, if any, and interest on, the Notes.


 


Section 7.6           Compensation and Indemnity.


 


The Company shall pay to the Trustee (acting
in any capacity hereunder) from time to time such compensation for its services as the Company and the Trustee shall agree in writing. 
The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust.  The Company
shall reimburse the Trustee upon request for all reasonable out-of-pocket expenses incurred by it.  Such expenses shall include
the reasonable compensation and expenses of the Trustee’s agents and counsel.


 


The Company shall fully indemnify the Trustee
(acting in any capacity hereunder) or any predecessor Trustee and their agents (including the cost of defending itself against
any claim (whether asserted by the Company, or any Holder or any other Person)) against any and all losses, damages, claims, liability,
fees, costs or expenses, including taxes (other than taxes based upon, measured by or determined by the income of the Trustee)
incurred by it except as set forth in the next paragraph in the performance of their duties under this Indenture as Trustee or
Agent, including, without limitation, reasonable attorneys’ fees and expenses and court costs incurred in connection with
any action, claim or suit brought to enforce the Trustee’s right to compensation, reimbursement or indemnification. 
The Trustee shall notify the Company promptly of any claim of which a Responsible Officer has received notice for which it may
seek indemnity.  The Company shall defend the claim and the Trustee shall cooperate in the defense.  The Trustee may
have separate counsel and the Company shall pay the reasonable fees and expenses of such counsel.  The Company need not pay
for any settlement made without its consent, which consent shall not be unreasonably withheld.  This indemnification shall
apply to officers, directors, employees, shareholders and agents of the Trustee and any Agent.


 






    83


     


    

 


The Company need not reimburse any expense
or indemnify against any loss or liability incurred by the Trustee or by any officer, director or employee of the Trustee caused
by its own negligence or willful misconduct as determined by a court of competent jurisdiction in a final, non-appealable order.


 


To secure the Company’s payment obligations
in this Section, the Trustee shall have a lien prior to the Notes on all money or property held or collected by the Trustee, except
that held in trust to pay principal and interest on the Notes.


 


When the Trustee incurs expenses or renders
services after an Event of Default specified in Section 6.1(g) or (h) (or any comparable provisions set forth in
a supplemental indenture) occurs, the expenses and the compensation for the services are intended to constitute expenses of administration
under any Bankruptcy Law.


 


The provisions of this Section shall
survive the termination of this Indenture and the resignation or removal of the Trustee.


 


Section 7.7           Replacement of Trustee.


 


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


 


The Trustee may resign by so notifying the
Company in writing.  The Holders of a majority in principal amount of the Notes may remove the Trustee by so notifying the
Trustee and the Company in writing not less than 30 days prior to the effective date of such removal.


 


The Company may remove the Trustee if:


 


(a)           the
Trustee fails to comply with Section 7.9;


 


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


 


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


 


(d)           the
Trustee becomes incapable of acting.


 


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


 



    84


     


    




 


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


 


If the Trustee fails to comply with Section 7.9,
any Holder, who has been a Holder for at least six months, may petition any court of competent jurisdiction for the removal of
the Trustee and the appointment of a successor Trustee.


 


A successor Trustee shall deliver a written
acceptance of its appointment to the retiring Trustee and to the Company.  Promptly after that, the retiring Trustee shall,
upon payment of its charges hereunder, transfer all property held by it as Trustee to the successor Trustee subject to the lien
provided for in Section 7.6, the resignation or removal of the retiring Trustee shall become effective, and the successor
Trustee shall have all the rights, powers and duties of the Trustee under this Indenture.  A successor Trustee shall mail
a notice of its succession to each Holder.


 


Notwithstanding replacement of the Trustee
pursuant to this Section 7.7, the Company’s obligations under Section 7.6 shall continue for the benefit of the
retiring trustee with respect to expenses and liabilities incurred by it prior to such replacement.


 


Any resigning or removed Trustee shall have
no responsibility or liability for any action or inaction of any successor Trustee.


 


Section 7.8           Successor Trustee by Merger, Etc.


 


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


 


Section 7.9           Eligibility; Disqualification.


 


This Indenture shall always have a Trustee
that is a corporation, national association or other business entity 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, and that is subject
to supervision or examination by U.S. federal or state authorities.  The Trustee shall always have a combined capital and
surplus of at least $50,000,000 as set forth in its most recent published annual report of condition.


 


Section 7.10         Agents.


 


The rights, privileges, protections, immunities
and benefits given to the Trustee, including, without limitation, its right to be compensated, reimbursed (including for any applicable
value added tax) and indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder,
and to each Agent.  For avoidance of doubt, the provisions of this Article VII (other than Section 7.1(a)) shall
be applicable to all Agents whether or not such Agent is an affiliate of the Trustee.


 






    85


     


    

 


Article VIII.

LEGAL DEFEASANCE AND COVENANT DEFEASANCE


 


Section 8.1           Option to Effect Legal Defeasance or Covenant Defeasance.


 


The Company may, at the option of its Board
of Directors evidenced by a resolution set forth in an Officers’ Certificate, at any time, elect to have either Section 8.2
or 8.3 be applied to all of its obligations discharged with respect to outstanding Notes upon compliance with the conditions set
forth below in this Article VIII.


 


Section 8.2           Legal Defeasance and Discharge.


 


Upon the Company’s exercise under Section 8.1
of the option applicable to this Section 8.2, each of the Company and the Subsidiary Guarantors, if any, shall, subject to
the satisfaction of the conditions set forth in Section 8.4, be deemed to have been discharged from its obligations with respect
to all outstanding Notes and related Note Guarantees on the date the conditions set forth below are satisfied (hereinafter, “Legal
Defeasance”).  For this purpose, Legal Defeasance means that the Company shall be deemed to have paid and discharged
the entire Indebtedness represented by the outstanding Notes, which shall thereafter be deemed to be “outstanding”
only for the purposes of Section 8.5 and the other Sections of this Indenture referred to in (a) and (b) below,
and to have satisfied all its other obligations under such Notes and this Indenture as it relates to such Notes (and the Trustee,
on demand of and at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following
provisions which shall survive until otherwise terminated or discharged hereunder:  (a) the rights of Holders of outstanding
Notes to receive solely from the trust fund described in Section 8.4, and as more fully set forth in such section, payments
in respect of the principal of, premium, if any, and interest on such Notes when such payments are due, (b) the Company’s
and Subsidiary Guarantors’ obligations with respect to the Notes under Article II, (c) the rights, powers, trusts,
duties and immunities of the Trustee hereunder and the Company’s and the Subsidiary Guarantors’ obligations in connection
therewith and (d) this Article VIII.  Subject to compliance with this Article VIII, the Company may exercise
its option under this Section 8.2 notwithstanding the prior exercise of its option under Section 8.3.


 


Section 8.3           Covenant Defeasance.


 


Upon the Company’s exercise under Section 8.1
of the option applicable to this Section 8.3, each of the Company and the Subsidiary Guarantors, if any, shall, subject to
the satisfaction of the conditions set forth in Section 8.4, be released from its obligations under Article IV (other
than Sections 4.1, 4.5, 4.7 and 4.18) and Article V with respect to the outstanding Notes and related Note Guarantees on and
after the date the conditions set forth below are satisfied (hereinafter, “Covenant Defeasance”), and such Notes shall
thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of
Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed “outstanding”
for all other purposes hereunder (it being understood that such Notes shall not be deemed outstanding for accounting purposes). 
For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes, the Company and the Subsidiary Guarantors
may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant,
whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference
in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a
Default or an Event of Default under Section 6.1, but, except as specified above, the remainder of this Indenture, such Notes
and the related Note Guarantees, if any, shall be unaffected thereby.  In addition, upon the Company’s exercise under
Section 8.1 of the option applicable to this Section 8.3, subject to the satisfaction of the conditions set forth in
Section 8.4, Sections 6.1(c) through 6.1(f) and 6.1(i) shall not constitute Events of Default.






    86


     


    

 





Section 8.4           Conditions to Legal or Covenant Defeasance.


 


The following shall be the conditions to the
application of either Section 8.2 or 8.3 to the outstanding Notes:


 


In order to exercise either Legal Defeasance
or Covenant Defeasance:


 


(a)           the
Company must irrevocably deposit with the Trustee, in trust, for the benefit of Holders, cash in U.S. Dollars for the Notes, non-callable
Government Securities, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized
firm of independent public accountants, to pay the principal of, premium, if any, and interest on the outstanding Notes on the
Stated Maturity or on the applicable redemption date, as the case may be, of such principal or installment of principal of, premium,
if any, or interest on the outstanding Notes;


 


(b)           in the case of Legal Defeasance, the Company shall have delivered to the Trustee an Opinion of Counsel reasonably acceptable
to the Trustee confirming that (i) the Company has received from, or there has been published by, the IRS a ruling or (B) since
the date hereof, there has been a change in the applicable U.S. federal income tax law, in either case to the effect that, and
based thereon such Opinion of Counsel shall confirm that, Holders and beneficial owners of the outstanding Notes will not recognize
income, gain or loss for U.S. federal income tax purposes as a result of such Legal Defeasance and will be subject to U.S. federal
income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had
not occurred;


 


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


 


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


 






    87


     


    

 


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


 


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


 


(g)           the
Company shall have delivered 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.


 


Section 8.5           Deposited Money and Government Securities to be Held in Trust; Other Miscellaneous Provisions.


 


Subject to Section 8.6, 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 8.5, the “Trustee”) pursuant to Section 8.4 in respect of the outstanding Notes
subject to a Legal Defeasance or a Covenant Defeasance shall be held in trust and applied by the Trustee, in accordance with the
provisions of such Notes and this Indenture, to the payment, either directly or through any paying agent (including the Company
acting as paying agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in
respect of principal, premium, if any, and interest, but such money need not be segregated from other funds except to the extent
required by law.


 


The Company and the Subsidiary Guarantors
shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or non-callable
Government Securities deposited pursuant to Section 8.4 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 subject to a Legal Defeasance
or a Covenant Defeasance.


 


Anything in this Article VIII to the
contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon the request of the Company any
money or non-callable Government Securities held by it as provided in Section 8.4 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 8.4(a)), are in excess of the amount thereof that would then be required to be deposited to
effect an equivalent Legal Defeasance or Covenant Defeasance.


 






    88


     


    

 


Section 8.6           Repayment to Company.


 


Any money deposited with the Trustee or any
paying agent, or then held by the Company, in trust for the payment of the principal of, premium, if any, or interest, if any,
on any Notes subject to a Legal Defeasance or a Covenant Defeasance and remaining unclaimed for two years after such principal,
and premium, if any, or interest, if any, have become due and payable, subject to applicable abandoned property law, shall be paid
to the Company on its request or (if then held by the Company) shall be discharged from such trust; and the Holders of such Notes
shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee
or such paying agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease.


 


Section 8.7           Reinstatement.


 


If the Trustee or paying agent is unable to
apply any U.S. Dollars or non-callable Government Securities in accordance with Section 8.2 or 8.3, as the case may be, by
reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application,
then the Company’s obligations under this Indenture, the Notes and the related Note Guarantees, if any, shall be revived
and reinstated as though no deposit had occurred pursuant to Section 8.2 or 8.3 until such time as the Trustee or paying agent
is permitted to apply all such money in accordance with Section 8.2 or 8.3, as the case may be; provided, however,
that, if the Company make any payment of principal of, premium, if any, or interest, if any, on any such Notes following the reinstatement
of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the
money held by the Trustee or paying agent.


 


Article IX.

AMENDMENTS AND WAIVERS


 


Section 9.1           Without Consent of Holders.


 


Notwithstanding Section 9.2, without
the consent of any Holder, the Company and the Trustee may amend or supplement this Indenture or the Notes:


 


(a)           to
cure any ambiguity, defect or inconsistency,


 


(b)           to
provide for uncertificated Notes in addition to or in place of certificated Notes (provided that the uncertificated Notes are
issued in registered form for purposes of Section 163(f) of the Code),


 


(c)           to
provide for the assumption of the Company’s or a Guarantor’s obligations to Holders in the case of a merger or consolidation,


 


(d)           to make any change that would provide any additional rights or benefits to Holders (including providing for additional Note
Guarantees) or that does not adversely affect the legal rights of any such Holder under this Indenture,


 


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


 






    89


     


    




 


(f)            to conform the text of this Indenture, the Notes or the Note Guarantees to any provision of the “Description of the
notes” section of the Company’s Offering Memorandum dated September 4, 2019, relating to the initial offering of the
Notes, to the extent that such provision in that “Description of the notes” was intended to be a verbatim recitation
of a provision of this Indenture, the Notes or the Note Guarantees, which intent may be evidenced by an Officers’ Certificate
delivered to the Trustee to that effect.


 


Upon the request of the Company accompanied
by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental Indenture, and upon receipt
by the Trustee of the documents described in Section 7.2, the Trustee shall join with the Company and the Subsidiary Guarantors
in the execution of any amended or supplemental Indenture authorized or permitted by the terms of this Indenture and to make any
further appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to enter
into such amended or supplemental Indenture that affects its own rights, duties or immunities under this Indenture or otherwise.


 


For the avoidance of doubt, no amendment to,
or deletion of any of the covenants described in Article IV or action taken in compliance with the covenants in effect at
the time of such action, shall be deemed to impair or affect any rights of any Holders to receive payment of principal of or premium,
if any, or interest on the Notes or to institute suit for the enforcement of any payment on or with respect to such Holder’s
Notes.


 


Section 9.2           With
Consent of Holders.


 


Except as provided in Section 9.1 and
Section 9.3, this Indenture and the Notes may be amended or supplemented with the consent of Holders of at least a majority
in principal amount of Notes then outstanding affected by the supplemental indenture implementing such amendment or supplement
(including consents obtained in connection with a tender offer or exchange offer for Notes), and, subject to Sections 6.8
and 6.12, any existing Default or Event of Default (other than a Default or Event of Default in the payment of the principal of,
premium, if any, or interest on the Notes, except a payment default resulting from an acceleration that has been rescinded) or
compliance with any provision of this Indenture or the Notes may be waived with the consent of Holders of a majority in principal
amount of Notes then outstanding affected by such supplemental indenture implementing such amendment or supplement (including consents
obtained in connection with a tender offer or exchange offer for Notes).


 


It shall not be necessary for the consent
of the Holders under this Section 9.2 to approve the particular form of any proposed amendment or waiver, but it shall be
sufficient if such consent approves the substance thereof.  After a supplemental indenture or waiver under this Section 9.2
becomes effective, the Company shall deliver to the Holders affected thereby a notice briefly describing the supplemental indenture
or waiver.  Any failure by the Company to mail such notice, or any defect therein, shall not, however, in any way impair or
affect the validity of any such supplemental indenture or waiver.


 






    90


     


    

 


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 reasonably satisfactory to the Trustee of the consent of the Holders as aforesaid, and upon
receipt by the Trustee of the documents described in Section 7.2, the Trustee shall join with the Company and the Subsidiary
Guarantors in the execution of such amended or supplemental Indenture unless such amended or supplemental Indenture affects the
Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion,
but shall not be obligated to, enter into such amended or supplemental Indenture.


 


Section 9.3           Limitations.


 


Without the consent of each affected Holder
of the Notes, an amendment or waiver may not (with respect to any Notes held by a non-consenting Holder):


 


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


 


(b)           reduce the principal of or change the fixed maturity of any Note or alter any of the provisions with respect to the redemption
of any Note in a manner adverse to the Holder of such Note;


 


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


 


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


 


(e)           
make any Note payable in a currency other than that stated in such Note;


 


(f)            make
any change in the provisions of this Indenture relating to waivers of past Defaults or the legal rights of Holders to receive
payments of principal of or premium, if any, or interest on the Notes;


 


(g)           waive
a redemption payment with respect to any Note (other than a payment required by Section 4.16 or 4.17 hereof);


 


(h)           except pursuant to this Indenture, release any Subsidiary Guarantor from its obligations under its Note Guarantee, or change
any Note Guarantee in any manner that would materially adversely affect Holders; or


 


(i)            make
any change in the foregoing amendment and waiver provisions.


 


It shall not be necessary for the consent
of the Holders under this Section 9.3 to approve the particular form of any proposed amendment or waiver, but it shall be sufficient
if such consent approves the substance thereof.

Section 9.4           [Reserved].


 


Section 9.5           Revocation and Effect of Consents.


 


Until an amendment 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 his Note or portion
of a Note if the Trustee receives the notice of revocation before the date the amendment or waiver becomes effective.


 


Any amendment or waiver once effective shall
bind every Holder of a Note affected by such amendment or waiver unless it is of the type described in any of clauses (a) through
(h) of Section 9.3.  In that case, the amendment or waiver shall bind each Holder of a Note who has consented to
it and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note.


 


Section 9.6           Notation
on or Exchange of Notes.


 


The Trustee may place an appropriate notation
about an amendment or waiver on any Note thereafter authenticated.  The Company in exchange for Notes may issue and the Trustee
shall authenticate upon request new Notes that reflect the amendment or waiver.


 


Section 9.7           Trustee to Sign Amendments; Trustee Protected.


 


The Trustee shall sign any amended or supplemental
Indenture authorized pursuant to this Article IX if the amendment or supplement does not adversely affect the rights, duties,
liabilities or immunities of the Trustee.  In executing, or accepting the additional trusts created by, any supplemental indenture
permitted by this Article or the modifications thereby of the trusts created by this Indenture, the Trustee shall be provided
with, and (subject to Section 7.1) shall be fully protected in conclusively relying upon, an Opinion of Counsel and Officers’
Certificate stating that the execution of such supplemental indenture is authorized or permitted by this Indenture, complying with
the requirements of Sections 10.4 and 10.5, and covering such other matters as the Trustee may reasonably require, including
that such supplemental indenture is the legal, valid and binding obligation of the Company and the Subsidiary Guarantors, enforceable
against the Company and the Subsidiary Guarantors in accordance with its terms.


 


Promptly after the execution by the Company
and the Trustee of any supplemental indenture pursuant to the provisions of this Section, the Trustee shall transmit a copy of
such supplemental indenture or a notice provided by the Company to the Trustee setting forth in general terms the substance of
such supplemental indenture, to the Holders affected thereby.  In the case of certificated Notes, such notice shall be sent
by mail, first class postage prepaid, to the Holders affected thereby as their names and addresses appear upon the Note Register. 
Any failure of the Trustee to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity
of any such supplemental indenture.

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

of such Notes, cash in U.S. Dollars, non-callable Government Securities, or a combination thereof, in amounts as will be sufficient,

(b)           in respect of clause (a)(ii), no Default or Event of Default has occurred and is continuing on the date of the deposit
(other than a Default or Event of Default resulting from 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 other instrument to which the Company or any Subsidiary Guarantor
is a party or by which the Company or any Subsidiary Guarantor is bound (other than with respect to the borrowing of funds to be
applied concurrently to make the deposit required to effect such satisfaction and discharge and any similar concurrent deposit
relating to other Indebtedness, and in each case the granting of Liens to secure such borrowings);


 


(c)           the
Company or any Subsidiary Guarantor has paid or caused to be paid all sums payable by it under this Indenture;


 


(d)           the
Company has delivered irrevocable instructions to the Trustee to apply the deposited money toward the payment of the Notes at
maturity or on the redemption date, as the case may be; and

Section 11.13       Judgment Currency.


 


The Company agrees, to the fullest extent
that it may effectively do so under applicable law, that (a) if for the purpose of obtaining judgment in any court it is necessary
to convert the sum due in respect of the principal of or interest or other amount on the Notes (the “Required Currency”)
into a currency in which a judgment will be rendered (the “Judgment Currency”), the rate of exchange used shall be
the rate at which in accordance with normal banking procedures such foreign exchange agent appointed by the Company could purchase
in The City of New York the Required Currency with the Judgment Currency on the day on which final unappealable judgment is entered,
unless such day is not a New York Banking Day, then, the rate of exchange used shall be the rate at which in accordance with normal

Article XII.

NOTE GUARANTEES


 


Section 12.1         Note Guarantee.


 


Each Subsidiary Guarantor that is a signatory
hereto and each Subsidiary of the Company that is required to become party to this Indenture as a Subsidiary Guarantor upon execution
of a supplemental indenture, hereby jointly and severally, unconditionally guarantees to each Holder of a Note authenticated and
delivered by the Trustee irrespective of the validity or enforceability of this Indenture, the Notes or the obligations of the
Company under this Indenture or the Notes, that:  (i) the principal of and interest on the Notes will be paid in full
when due, whether at the maturity or interest payment or mandatory redemption date, by acceleration, call for redemption or otherwise,
and interest on the overdue principal of and interest, if any, on the Notes and all other obligations of the Company to the Holders
or the Trustee under this Indenture or the Notes will be promptly paid in full or performed, all in accordance with the terms of
this Indenture and the Notes; and (ii) in case of any extension of time of payment or renewal of any Notes or any of such
other obligations, they will be paid in full when due or performed in accordance with the terms of the extension or renewal, whether
at maturity, by acceleration or otherwise.  Failing payment when due of any amount so guaranteed for whatever reason, each
Subsidiary Guarantor will be obligated to pay the same whether or not such failure to pay has become an Event of Default which
could cause acceleration pursuant to Section 6.2.  Each Subsidiary Guarantor agrees that this is a guarantee of payment
not a guarantee of collection.


 






    98


     


    

 


Each Subsidiary Guarantor hereby agrees that
its obligations with regard to this Note Guarantee shall be joint and several and unconditional, irrespective of the validity or
enforceability of the Notes or the obligations of the Company under this Indenture, the absence of any action to enforce the same,
the recovery of any judgment against the Company or any other obligor with respect to this Indenture, the Notes or the obligations
of the Company under this Indenture or the Notes, any action to enforce the same or any other circumstances (other than complete
performance) which might otherwise constitute a legal or equitable discharge or defense of a Subsidiary Guarantor.  Each Subsidiary
Guarantor further, to the extent permitted by law, waives and relinquishes all claims, rights and remedies accorded by applicable
law to guarantors and agrees not to assert or take advantage of any such claims, rights or remedies, including but not limited
to:  (a) any right to require the Trustee, the Holders or the Company (each, a “Benefited Party”) to proceed
against the Company or any other Person or to proceed against or exhaust any security held by a Benefited Party at any time or
to pursue any other remedy in any Benefited Party’s power before proceeding against such Subsidiary Guarantor; (b) the
defense of the statute of limitations in any action hereunder or in any action for the collection of any Indebtedness or the performance
of any obligation hereby guaranteed; (c) any defense that may arise by reason of the incapacity, lack of authority, death
or disability of any other Person or the failure of a Benefited Party to file or enforce a claim against the estate (in administration,
bankruptcy or any other proceeding) of any other Person; (d) demand, protest and notice of any kind including but not limited
to notice of the existence, creation or incurring of any new or additional Indebtedness or obligation or of any action or non-action
on the part of such Subsidiary Guarantor, the Company, any Benefited Party, any creditor of such Subsidiary Guarantor, the Company
or on the part of any other Person whomsoever in connection with any Indebtedness or obligations hereby guaranteed; (e) any
defense based upon an election of remedies by a Benefited Party, including but not limited to an election to proceed against such
Subsidiary Guarantor for reimbursement; (f) any defense based upon any statute or rule of law which provides that the
obligation of a surety must be neither larger in amount nor in other respects more burdensome than that of the principal; (g) any
defense arising because of a Benefited Party’s election, in any proceeding instituted under Bankruptcy Law, of the application
of 11 U.S.C. Section 1111 (b)(2); or (h) any defense based on any borrowing or grant of a security interest under
11 U.S.C. Section 364.  Each Subsidiary Guarantor hereby covenants that its Note Guarantee will not be discharged
except by complete performance of the obligations contained in its Note Guarantee and this Indenture.


 


If any Holder or the Trustee is required by
any court or otherwise to return to either the Company or any Subsidiary Guarantor, or any Custodian acting in relation to either
the Company or such Subsidiary Guarantor, any amount paid by the Company or such Subsidiary Guarantor to the Trustee or such Holder,
the applicable Note Guarantees, to the extent theretofore discharged, shall be reinstated and be in full force and effect. 
Each Subsidiary 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 Subsidiary Guarantor further agrees that,
as between such Subsidiary Guarantor, on the one hand, and the Holders and the Trustee, on the other hand, (i) the maturity
of the obligations guaranteed hereby may be accelerated as provided in Section 6.2 for the purposes of this Note Guarantee,
notwithstanding any stay, injunction or other prohibition preventing such acceleration as to the Company or any other obligor on
the Notes of the obligations guaranteed hereby, and (ii) in the event of any declaration of acceleration of those obligations
as provided in Section 6.2, those obligations (whether or not due and payable) will forthwith become due and payable by such
Subsidiary Guarantor for the purpose of this Note Guarantee.


 






    99


     


    

 


Section 12.2         Limitation of Subsidiary Guarantor’s Liability.


 


Each Subsidiary Guarantor and, by its acceptance
hereof, the Trustee and each Holder hereby confirm that it is its intention that the Note Guarantee of such Subsidiary Guarantor
not constitute a fraudulent transfer or conveyance for purposes of the Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the
Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to any Note Guarantee.  To effectuate
the foregoing intention, each such Person hereby irrevocably agrees that the obligation of such Subsidiary Guarantor under its
Note Guarantee under this Article XII shall be limited to the maximum amount as will, after giving effect to such maximum
amount and all other (contingent or other) liabilities of such Subsidiary 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 Subsidiary
Guarantor in respect of the obligations of such other Subsidiary Guarantor under this Article XII, result in the obligations
of such Subsidiary Guarantor in respect of such maximum amount not constituting a fraudulent transfer or conveyance under said
laws.  The Trustee and each Holder by accepting the benefits hereof, confirms its intention that, in the event of a bankruptcy,
reorganization or other similar proceeding of the Company or any Subsidiary Guarantor in which concurrent claims are made upon
such Subsidiary Guarantor hereunder, to the extent such claims will not be fully satisfied, each such claimant with a valid claim
against the Company shall be entitled to a ratable share of all payments by such Subsidiary Guarantor in respect of such concurrent
claims.


 


Article XIII.

USA PATRIOT ACT


 


Section 13.1         USA Patriot Act.


 


The parties hereto acknowledge that in accordance
with Section 326 of the USA Patriot Act, the Trustee, like all financial institutions and in order to help fight the funding
of terrorism and money laundering, is required to obtain, verify, and record information that identifies each person or legal entity
that establishes a relationship or opens an account with the Trustee.  The parties to this Indenture agree that they will
provide the Trustee with such information as it may reasonably request in order for the Trustee to satisfy the requirements of
the USA Patriot Act.

“Indenture”), among the Company, the Subsidiary Guarantors and the Trustee.  The terms of the Notes include those

price of 104.875% of the principal amount thereof, plus, in each case, accrued and unpaid interest to, but excluding, the applicable
redemption date, with cash in an amount not greater than the net cash proceeds of one or more Qualified Equity Offerings; provided
that:  (i) at least 50% of the aggregate principal amount of the Notes (excluding any Additional Notes) issued under
the Indenture remains outstanding immediately after the occurrence of such redemption (excluding Notes held by the Company or any

Equity Offering.


 



    A-5

Holder’s address of record.  The Notes in denominations larger than $2,000 may be redeemed in part but only in integral
multiples of $1,000 in excess thereof, unless all the Notes held by a Holder are to be redeemed.  In the event of a redemption
of less than all of the Notes, the Notes will be chosen for redemption by the Trustee (or the registrar, as applicable) in accordance
with the Indenture.  On and after the redemption date, interest ceases to accrue on the Notes or portions of them called for
redemption.


 


If this Note is redeemed subsequent to a record
date with respect to any Interest Payment Date specified above and on or prior to such Interest Payment Date, then any accrued
interest will be paid to the Person in whose name this Note is registered at the close of business on such record date.


 


7.            MANDATORY REDEMPTION.  Except as set forth in paragraph 8 below, the Company shall not be required to

    A-6


     


    

 





11.            AMENDMENT, SUPPLEMENT AND WAIVER.  Subject to certain exceptions, the Indenture with respect to the Notes
or the Notes may be amended or supplemented with the written consent of the Holders of a majority in principal amount of the Notes
and any existing default or compliance with any provision of the Indenture with respect to the Notes or the Notes may be waived
with the consent of the Holders of a majority in principal amount of the Notes (including, in each case, Additional Notes, if any). 
Without the consent of any Holder of the Notes, the Indenture with respect to the Notes or the Notes may be amended or supplemented
to, in addition to other events more fully described in the Indenture, cure any ambiguity, defect or inconsistency, provide for
uncertificated Notes in addition to or in place of certificated Notes, provide for the assumption of the Company’s obligations
to Holders of the Notes in the case of a merger or consolidation or make any change that would provide any additional rights or
benefits to the Holders of the Notes or that does not adversely affect the legal rights under the Indenture of any such Holder.


 


12.            DEFAULTS AND REMEDIES.  An Event of Default with respect to the Notes occurs upon the occurrence of any
of the following events:  the default for 30 days in payment when due of interest on the Notes; the default in payment
when due of the principal of or premium, if any, on the Notes; the failure by the Company to comply with Section 4.17 of the
Indenture; the failure by the Company or any of the Restricted Subsidiaries for 60 days after written notice from the Trustee or
Holders of not less than 25% of the aggregate principal amount of the then outstanding Notes (including Additional Notes, if any)
to comply with any of its other agreements in the Indenture, Notes or the Note Guarantees; the failure to pay at final maturity
(giving effect to any applicable grace periods and any extensions thereof) the stated principal amount of any Indebtedness of the
Company or any Restricted Subsidiary, or the acceleration of the final stated maturity of any such Indebtedness (which acceleration
is not rescinded, annulled or otherwise cured within 30 days of receipt by the Company or such Restricted Subsidiary of notice
of any such acceleration) if the aggregate principal amount of such Indebtedness, together with the principal amount of any other
such Indebtedness in default for failure to pay principal at final stated maturity or which has been so accelerated (in each case
with respect to which the 30-day period described above has passed), equals $200.0 million or more at any time; the failure
by the Company or any Restricted Subsidiary to pay final judgments aggregating in excess of $200.0 million, which judgments
remain unpaid, undischarged or unstayed for a period of 60 days; certain events of bankruptcy or insolvency with respect to
the Company or any Restricted Subsidiary that is a Significant Subsidiary; or except as permitted by the Indenture or the Note
Guarantees, any Note Guarantee shall be held in any judicial proceeding to be unenforceable or invalid or shall cease for any reason
to be in full force and effect, or the Company or any Restricted Subsidiary or any Person acting on behalf of the Company or any
Restricted Subsidiary shall deny or disaffirm in writing its obligations under its Note Guarantee.


 


In the case of an Event of Default arising
from certain events of bankruptcy or insolvency, with respect to the Company, any Restricted Subsidiary that is a Significant Subsidiary
or any group of Restricted Subsidiaries 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 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.


 


Subject to certain limitations, Holders of
a majority in aggregate principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power. 
The Trustee will be required to give notice to Holders within 90 days after a default of which the Trustee has actual knowledge
under the Indenture unless the default has been cured or waived.  The Trustee may withhold from Holders notice of any continuing
Default or Event of Default if it determines that withholding notice is in their interest, except a Default or Event of Default
relating to the payment of principal of, premium on, if any, and interest on the Notes.


 



    A-7


     


    

 





Subject to the provisions of the Indenture
relating to the duties of the Trustee, in case an Event of Default occurs and is continuing, the Trustee will be under no obligation
to exercise any of the rights or powers under the Indenture at the request or direction of any Holders unless such Holders have
offered the Trustee indemnity or security reasonably acceptable to it against any cost, liability or expense incurred in compliance
with such request.  Except to enforce the right to receive payment of principal, premium, if any, or interest, if any, when
due, no Holder shall have any right to institute any proceeding, judicial or otherwise, with respect to the Indenture, or for the
appointment of a receiver or trustee, or for any other remedy thereunder, unless:  such Holder has previously given written
notice to the Trustee of a continuing Event of Default; Holders of at least 25% in aggregate principal amount of the then outstanding
Notes shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name
as Trustee under the Indenture; such Holder or Holders offer and, if requested, provide to the Trustee security or indemnity satisfactory
to it against any costs, expenses and liabilities to be incurred in compliance with such request; the Trustee does not comply with
such request within 60 days after its receipt of such request and offer of security or indemnity; and 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 written request.


 


The Holders of a majority in aggregate principal
amount of the then outstanding Notes by written notice to the Trustee may, on behalf of all Holders, rescind an acceleration or
waive any existing Default or Event of Default and its consequences under the Indenture, if the rescission would not conflict with
any judgment or decree, except a continuing Default or Event of Default in the payment of principal of, premium on, if any, or
interest on, the Notes.


 


13.            NOTE GUARANTEES.  Payment of principal of, premium, if any, and interest (including interest on overdue
principal, if any, and interest, if lawful) on the Notes is guaranteed on an unsecured, senior basis by the Subsidiary Guarantors
pursuant to Article XII of the Indenture.


 


14.            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. Under no circumstances shall the Trustee be liable in its individual capacity for the
obligations evidenced by the Notes.


 


15.            NO RECOURSE AGAINST OTHERS.  No director, officer, employee, incorporator or stockholder, as such, of
the Company or any Subsidiary Guarantor shall have any liability for any obligations of the Company or any Subsidiary Guarantor
under the Notes, the Note Guarantees or the Indenture or for any claim based on, in respect of or by reason of such obligations
or their creation.  Each Holder by accepting a Note and the related Note Guarantees waives and releases all such liability. 
The waiver and release are part of the consideration for the issuance of the Notes and the Note Guarantees.

is not rescinded, annulled or otherwise cured within 30 days of receipt by the Company or such Restricted Subsidiary of notice
of any such acceleration) if the aggregate principal amount of such Indebtedness, together with the principal amount of any other
such Indebtedness in default for failure to pay principal at final stated maturity or which has been so accelerated (in each case
with respect to which the 30-day period described above has passed), equals $200.0 million or more at any time; the failure
by the Company or any Restricted Subsidiary to pay final judgments aggregating in excess of $200.0 million, which judgments
remain unpaid, undischarged or unstayed for a period of 60 days; certain events of bankruptcy or insolvency with respect to
the Company or any Restricted Subsidiary that is a Significant Subsidiary; or except as permitted by the Indenture or the Note
Guarantees, any Note Guarantee shall be held in any judicial proceeding to be unenforceable or invalid or shall cease for any reason
to be in full force and effect, or the Company or any Restricted Subsidiary or any Person acting on behalf of the Company or any
Restricted Subsidiary shall deny or disaffirm in writing its obligations under its Note Guarantee.


 


In the case of an Event of Default arising
from certain events of bankruptcy or insolvency, with respect to the Company, any Restricted Subsidiary that is a Significant Subsidiary
or any group of Restricted Subsidiaries 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 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.


 


Subject to certain limitations, Holders of
a majority in aggregate principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power. 
The Trustee will be required to give notice to Holders within 90 days after a default of which the Trustee has actual knowledge
under the Indenture unless the default has been cured or waived.  The Trustee may withhold from Holders notice of any continuing
Default or Event of Default if it determines that withholding notice is in their interest, except a Default or Event of Default
relating to the payment of principal of, premium on, if any, and interest on the Notes.


 



    B-7


     


    

 





Subject to the provisions of the Indenture
relating to the duties of the Trustee, in case an Event of Default occurs and is continuing, the Trustee will be under no obligation
to exercise any of the rights or powers under the Indenture at the request or direction of any Holders unless such Holders have
offered the Trustee indemnity or security reasonably acceptable to it against any cost, liability or expense incurred in compliance
with such request.  Except to enforce the right to receive payment of principal, premium, if any, or interest, if any, when
due, no Holder shall have any right to institute any proceeding, judicial or otherwise, with respect to the Indenture, or for the
appointment of a receiver or trustee, or for any other remedy thereunder, unless:  such Holder has previously given written
notice to the Trustee of a continuing Event of Default; Holders of at least 25% in aggregate principal amount of the then outstanding
Notes shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name
as Trustee under the Indenture; such Holder or Holders offer and, if requested, provide to the Trustee security or indemnity satisfactory
to it against any costs, expenses and liabilities to be incurred in compliance with such request; the Trustee does not comply with
such request within 60 days after its receipt of such request and offer of security or indemnity; and 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 written request.


 


The Holders of a majority in aggregate principal
amount of the then outstanding Notes by written notice to the Trustee may, on behalf of all Holders, rescind an acceleration or
waive any existing Default or Event of Default and its consequences under the Indenture, if the rescission would not conflict with
any judgment or decree, except a continuing Default or Event of Default in the payment of principal of, premium on, if any, or
interest on, the Notes.


 


13.            NOTE GUARANTEES.  Payment of principal of, premium, if any, and interest (including interest on overdue
principal, if any, and interest, if lawful) on the Notes is guaranteed on an unsecured, senior basis by the Subsidiary Guarantors
pursuant to Article XII of the Indenture.


 


14.            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. Under no circumstances shall the Trustee be liable in its individual capacity for the
obligations evidenced by the Notes.


 


15.            NO RECOURSE AGAINST OTHERS.  No director, officer, employee, incorporator or stockholder, as such, of
the Company or any Subsidiary Guarantor shall have any liability for any obligations of the Company or any Subsidiary Guarantor
under the Notes, the Note Guarantees or the Indenture or for any claim based on, in respect of or by reason of such obligations
or their creation.  Each Holder by accepting a Note and the related Note Guarantees waives and releases all such liability. 
The waiver and release are part of the consideration for the issuance of the Notes and the Note Guarantees.


 


16.            AUTHENTICATION.  This Note shall not be valid until authenticated by the manual signature of the Trustee
or the Authentication Agent.
