any test contained in this Indenture with respect to any period during which any Specified Transactions occur or, subsequent to
such period and prior to or simultaneously with the event for which the calculation is made, the Total Leverage Ratio, the Secured

by the Company in good faith) (i) (x) directly attributable to such transaction, (y) expected to have a continuing
impact on the Company and its Restricted Subsidiaries and (z) factually supportable or (ii) otherwise consistent with

applicable law, issue Additional Notes under this Indenture. The Notes issued on the Issue Date and any Additional Notes subsequently
issued will be treated as a single class for all purposes under this Indenture. Furthermore, in the case of Additional Notes having
the same “CUSIP” number as the Notes issued on the date hereof, such Additional Notes will be fungible with all other
Notes for U.S. federal income tax purposes. At any time and from time to time after the execution of this Indenture, the Trustee
will, upon receipt of a written order of the Company signed by at least one Officer of the Company (an “Authentication
Order”) and an Opinion of Counsel, authenticate Notes for (a) original issue in an aggregate principal amount
specified in such Authentication Order and (b) Additional Notes in such amounts as may be specified from time to time without
limit, so long as such issuance is permitted under Article IV of this Indenture and applicable law. The Authentication Order
will specify the amount of Notes to be authenticated and the date on which the Notes are to be authenticated.


 


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


 


Section 2.03            Registrar
and Paying Agent.


 


The Company will maintain an office or agency
where Notes may be presented for registration of transfer or for exchange (“Registrar”) and an office
or agency where Notes may be presented for payment (“Paying Agent”). The Registrar will keep a register
of the Notes and of their transfer and exchange.


 








    -30-


     


    

 



 


The Company may appoint one or more co-registrars
and one or more additional paying agents. The term “Registrar” includes any co-registrar and the term “Paying
Agent” includes any additional paying agent. The Company may change any Paying Agent or Registrar without notice to any Holder.
The Company will promptly notify the Trustee in writing of the name and address of any Agent not a party to this Indenture. If
the Company fails to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such. The Company
or any of its Subsidiaries may act as Paying Agent or Registrar.


 


The Company initially appoints The Depository
Trust Company (“DTC”) to act as Depositary with respect to the Global Notes. Neither the Trustee nor
any Agent shall have responsibility for any actions taken or not taken by DTC or any other Depositary.


 


The Company initially appoints the Trustee,
and the Trustee hereby agrees, to act as the Registrar and Paying Agent and to act as Custodian with respect to the Global Notes.
The Company has entered into a letter of representations with DTC in the form provided by DTC and the Trustee and each Agent are
hereby authorized to act in accordance with such letter and Applicable Procedures.


 


The Company will be responsible for making
calculations called for under the Notes, including determination of redemption price, premium, if any, and any additional amounts
or other amounts payable on the Notes. The Company will make the calculations in good faith and provide a schedule of its calculations
to the Trustee when requested by the Trustee, and the Trustee is entitled to rely conclusively on the accuracy of the Company’s
calculations without independent verification.


 


Section 2.04          Paying
Agent to Hold Money in Trust.


 


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


 


Section 2.05          Holder
Lists.


 


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


 


Section 2.06          Transfer
and Exchange.


 


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


 


(1)           the
Company delivers to the Trustee notice from the Depositary that it is unwilling or unable to continue to act as Depositary or that
it is no longer a clearing agency registered under the Exchange Act and, in either case, a successor Depositary is not appointed
by the Company within 90 days after the date of such notice from the Depositary;


 






    -31-


     


    

 


(2)           the
Company in its sole discretion determines that the Global Notes (in whole but not in part) should be exchanged for Definitive Notes
and delivers a written notice to such effect to the Trustee; or


 


(3)           there
has occurred and is continuing a Default or Event of Default with respect to the Notes.


 


Upon the occurrence of either of the preceding
events in (1) or (2) above, Definitive Notes shall be issued in such names as the Depositary shall instruct the Trustee,
and upon the occurrence of the preceding events in (3) above, Definitive Notes shall be issued in exchange for beneficial
interests in a Global Note upon request therefor by the Depositary acting upon instruction of the holder of such beneficial interest
in such Global Note. Global Notes also may be exchanged or replaced, in whole or in part, as provided in Sections 2.07 and 2.10.
Every Note authenticated and delivered in exchange for, or in lieu of, a Global Note or any portion thereof, pursuant to this Section 2.06
or Section 2.07 or 2.10, shall be authenticated and delivered in the form of, and shall be, a Global Note. A Global Note may
not be exchanged for another Note other than as provided in this Section 2.06(a), however, beneficial interests in a Global
Note may be transferred and exchanged as provided in Section 2.06(b) or (c). In connection with any proposed exchange
of a Global Note for a Definitive Note, the Company shall provide or cause to be provided to the Trustee all information reasonably
requested by the Trustee that is necessary to allow the Trustee to comply with any applicable tax reporting obligations. The Trustee
may rely on information provided to it and shall have no responsibility to verify or ensure the accuracy of such information.


 


(b)            Transfer
and Exchange of Beneficial Interests in the Global Notes. The transfer and exchange of beneficial interests in the Global Notes
will be effected through the Depositary, in accordance with the provisions of this Indenture and the Applicable Procedures. Beneficial
interests in the Restricted Global Notes will be subject to restrictions on transfer comparable to those set forth herein to the
extent required by the Securities Act. Transfers of beneficial interests in the Global Notes also will require compliance with
either subparagraph (1) or (2) below, as applicable, as well as one or more of the other following subparagraphs, as

benefit of a U.S. Person (other than the Initial Purchasers). Beneficial interests in any Unrestricted Global Note may be transferred
to Persons who take delivery thereof in the form of a beneficial interest in an Unrestricted Global Note. No written orders or
instructions shall be required to be delivered to the Registrar to effect the transfers described in this Section 2.06(b)(1).


 


(2)           All

the Registrar either:

(3)            Transfer

with the requirements of Section 2.06(b)(2) above and the Registrar receives the following:

principal amount of beneficial interests transferred pursuant to this subparagraph.


 


(4)            Transfer

for Definitive Notes or a particular Global Note has been redeemed, repurchased or canceled in whole and not in part, each such
Global Note will be returned to or retained and canceled by the Trustee in accordance with Section 2.11. At any time prior
to such cancellation, if any beneficial interest in a Global Note is exchanged for or transferred to a Person who will take delivery
thereof in the form of a beneficial interest in another Global Note or for Definitive Notes, the principal amount of Notes represented
by such Global Note will be reduced accordingly and an endorsement will be made on such Global Note by the Trustee or by the Depositary
at the direction of the Trustee to reflect such reduction; and if the beneficial interest is being exchanged for or transferred
to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note, such other Global Note

(h)            General
Provisions Relating to Transfers and Exchanges.


 


(1)           To
permit registrations of transfers and exchanges, the Company will execute and the Trustee will authenticate Global Notes and Definitive
Notes upon receipt of an Authentication Order in accordance with Section 2.02 or at the Registrar’s request.


 


(2)           No
service charge will be made to a Holder of a beneficial interest in a Global Note or to a Holder of a Definitive Note for any registration
of transfer or exchange, but the Company and the Trustee may require payment of a sum sufficient to cover any transfer tax or similar
governmental charge payable in connection therewith (other than any such transfer taxes or similar governmental charge payable
upon exchange or transfer pursuant to Sections 2.10, 3.06, 3.09, 4.10, 4.15 and 9.05).


 


(3)           The
Registrar will not be required to register the transfer of or exchange of any Note selected for redemption in whole or in part,
except the unredeemed portion of any Note being redeemed in part.


 


(4)           All
Global Notes and Definitive Notes issued upon any registration of transfer or exchange of Global Notes or Definitive Notes will
be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the
Global Notes or Definitive Notes surrendered upon such registration of transfer or exchange.


 


(5)           Neither
the Registrar nor the Company will be required:


 


(A)            to
issue, to register the transfer of or to exchange any Notes during a period beginning at the opening of business 15 days before
the day of any selection of Notes for redemption under Section 3.02 and ending at the close of business on the day of selection;

certifications, certificates and Opinions of Counsel required to be submitted to the Registrar pursuant to this Section 2.06

the Trustee nor the Registrar shall have any duty to monitor the Company’s compliance with or have any responsibility with
respect to the Company’s compliance with any federal or state securities laws in connection with registrations of transfers
and exchanges of the Notes. The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with
any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest
in any Notes (including any transfers between or among the Depository’s participants or beneficial owners of interests in
any Global Note) other than to require delivery of such certificates and other documentation, as is expressly required by, and
to do so if and when expressly required by, the terms of this Indenture or the Notes and to examine the same to determine substantial
compliance as to form with the express requirements hereof.


 


Section 2.07           Replacement
Notes.


 


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


 


Every replacement Note issued in accordance
with this Section 2.07 is an additional obligation of the Company and will be entitled to all of the benefits of this Indenture
equally and proportionately with all other Notes duly issued hereunder.


 


Section 2.08           Outstanding
Notes.


 


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


 


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


 


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


 


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


 


Section 2.09            Treasury
Notes.


 


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


 






    -41-


     


    

 


Section 2.10          Temporary
Notes.


 


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


 


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


 


Section 2.11           Cancellation.


 


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


 


Section 2.12           Defaulted
Interest.


 


If the Company defaults in a payment of
interest on the Notes, it will pay the defaulted interest in any lawful manner plus, to the extent lawful, interest payable
on the defaulted interest, to the Persons who are Holders on a subsequent special record date, in each case at the rate provided
in the Notes and in Section 4.01. The Company will notify the Trustee in writing of the amount of defaulted interest proposed
to be paid on each Note and the date of the proposed payment. The Company will fix or cause to be fixed each such special record
date and payment date; provided that no such special record date may be less than 10 days prior to the related payment date
for such defaulted interest. At least 15 days before the special record date, the Company (or, upon the written request of the
Company, the Trustee in the name and at the expense of the Company) will send or cause to be sent to Holders a notice that states
the special record date, the related payment date and the amount of such interest to be paid.


 


Section 2.13           CUSIP, ISIN
and Common Code Numbers.


 


The Company in issuing the Notes may use
“CUSIP” numbers, ISINs and “Common Code” numbers (in each case, if then generally in use) and, if
so, the Trustee will use “CUSIP” numbers, ISINs and “Common Code” numbers in notices as a convenience
to Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers
either as printed on the Notes or as contained in any notice and that reliance may be placed only on the other identification numbers
printed on the Notes, and any such notice will not be affected by any defect in or omission of such numbers. The Company will promptly
notify the Trustee in writing of any change in the “CUSIP” numbers, ISINs and “Common Code” numbers
applicable to the Notes.


 


ARTICLE III

REDEMPTION AND PREPAYMENT


 


Section 3.01           Notices
to Trustee.


 


If the Company elects to redeem Notes pursuant
to the optional redemption provisions of Section 3.07, it must furnish to the Trustee, at least 15 days but not more than
60 days before a redemption date, an Officer’s Certificate setting forth:


 






    -42-


     


    

 


(1)            the
clause of this Indenture pursuant to which the redemption shall occur;


 


(2)            the
redemption date;


 


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


 


(4)            that
the redemption complies with any applicable covenants or conditions precedent set forth in this Indenture; and


 


(5)            the
redemption price. If the redemption price is not known at the time such Officer’s Certificate is to be given, the actual
redemption price calculated as described in the terms of the Notes will be set forth in an Officer’s Certificate delivered
to the Trustee no later than two Business Days prior to the redemption date.


 


Section 3.02           Selection
of Notes to Be Redeemed or Purchased.


 


If less than all of the Notes are to be
redeemed or purchased in an offer to purchase at any time, Notes for redemption or purchase will be selected on a pro rata basis
or by such method as the Trustee deems fair and appropriate (or, in the case of Global Notes, beneficial interests in such Notes
may be selected for redemption by the applicable clearing system in accordance with customary procedures), in whole multiples of
$1,000.


 


In the event of partial redemption or purchase
of certificated Notes, the particular Notes to be redeemed or purchased will be selected, unless otherwise provided herein, not
less than 15 days nor more than 60 days prior to the redemption or purchase date by the Trustee from the outstanding Notes not
previously called for redemption or purchase.


 


The Trustee will promptly notify the Company
in writing of the certificated Notes selected for redemption or purchase and, in the case of any Note selected for partial redemption
or purchase, the principal amount thereof to be redeemed or purchased. Notes and portions of Notes selected will be in amounts
of $2,000 or whole multiples of $1,000 in excess thereof; except that if all of the Notes of a Holder are to be redeemed or purchased,
the entire outstanding amount of Notes held by such Holder, even if not in the amount of $2,000 or a whole multiple of $1,000 in
excess thereof, shall be redeemed or purchased. Except as provided in the preceding sentence, provisions of this Indenture that
apply to Notes called for redemption or purchase also apply to portions of Notes called for redemption or purchase.


 


Section 3.03           Notice
of Redemption.


 


Subject to the provisions of Section 3.09,
at least 15 days but not more than 60 days before a redemption date, the Company will send or cause to be sent a notice of redemption
to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be sent more than 60
days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge
of this Indenture pursuant to Articles VIII or XI hereof.


 


The notice will identify the Notes to be
redeemed and will state:


 


(1)            the
redemption date;


 


(2)            the
redemption price;


 


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


 


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


 






    -43-


     


    

 


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


 


(6)            that,
unless the Company defaults in making such redemption payment or any conditions precedent are not satisfied, interest on Notes
called for redemption ceases to accrue on and after the redemption date;


 


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


 


(8)            any
conditions precedent to such redemption described in reasonable detail; and


 


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


 


At the Company’s request, the Trustee
will give the notice of redemption in the Company’s name and at its expense; provided, however, that the Company
has delivered to the Trustee, at least 45 days prior to the redemption date (unless a shorter period shall be satisfactory to the
Trustee), an Officer’s Certificate requesting that the Trustee give such notice together with the notice to be given setting
forth the information to be stated in such notice as provided in the preceding paragraph.


 


Section 3.04           Effect
of Notice of Redemption.


 


Once notice of redemption is sent in accordance
with Section 3.03, Notes called for redemption become irrevocably due and payable on the redemption date at the redemption
price, subject to any applicable conditions stated therein.


 


Notices of any redemption of the Notes may
be subject to the satisfaction of one or more conditions precedent established by the Company, in its sole discretion. If applicable,
such notice shall state that, at the discretion of the Company, the redemption date may be delayed until such time as any or all
such conditions have been satisfied (or waived). In addition, the Company may provide in any such notice that payment of the redemption
price and the performance of its obligations with respect to such redemption may not be performed by another Person. The Company
will provide written notice to the Trustee prior to the close of business three Business Days prior to the redemption date (or
such shorter period as may be acceptable to the Trustee) if any such redemption has been rescinded or delayed, and upon receipt
the Trustee shall provide such notice to each Holder of the Notes in the same manner in which the notice of redemption was given.


 


Section 3.05           Deposit
of Redemption or Purchase Price.


 


One Business Day prior to the redemption
or purchase date, the Company will deposit with the Trustee or with the Paying Agent money sufficient to pay the redemption or
purchase price, as applicable, of and accrued and unpaid interest on all Notes to be redeemed or purchased on that date. The Trustee
or the Paying Agent will promptly return to the Company any money deposited with the Trustee or the Paying Agent by the Company
in excess of the amounts necessary to pay the redemption or purchase price of, and accrued and unpaid interest on, all Notes to
be redeemed or purchased.


 


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


 






    -44-


     


    

 


Section 3.06           Notes
Redeemed or Purchased in Part.


 


Upon surrender of a Note that is redeemed
or purchased in part, the Company will issue and, upon receipt of an Authentication Order, the Trustee will transfer by book entry
or authenticate for the Holder at the expense of the Company a new Note equal in principal amount to the unredeemed or unpurchased
portion of the Note surrendered.


 


Section 3.07           Optional
Redemption.


 


(a)           At
any time prior to August 15, 2023, the Company may on any one or more occasions redeem up to 40% of the aggregate principal

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


 


(b)           Any
redemption or notice of any redemption with the proceeds of an Equity Offering pursuant to Section 3.07(a) may, at the
Company’s discretion, be subject to one or more conditions precedent, including, but not limited to, completion of such Equity
Offering and may be given prior to the completion thereof.


 


(c)           At
any time prior to August 15, 2023, the Company may redeem all or a part of the notes upon notice as described in Section 3.03
at a redemption price equal to 100% of the principal amount of the notes redeemed plus the Applicable Premium as of, and
accrued and unpaid interest, if any, to, but excluding the date of redemption, subject to the rights of holders of record on the
relevant record date to receive interest due on the relevant interest payment date. Calculation of the Applicable Premium will
be made by the Company or on its behalf by such Person as the Company may designate; provided that such calculation or the
correctness thereof shall not be a duty or obligation of the Trustee.


 


(d)           Except
pursuant to paragraphs (a), (b) and (c) of this Section 3.07, the Notes will not be redeemable at the Company’s
option prior to August 15, 2023.

Unless the Company defaults in the payment
of the redemption price, interest will cease to accrue on the Notes or portions thereof called for redemption on and after the
applicable redemption date.


 


(f)           Any
redemption pursuant to this Section 3.07 shall be made pursuant to the provisions of Sections 3.01 through 3.06. For the avoidance
of doubt, the Company may at any time and from time to time purchase the Notes in the open market or otherwise.

Section 3.08           Mandatory
Redemption.


 


The Company is not required to make mandatory
redemption or sinking fund payments with respect to the Notes, other than as set forth in Section 3.10.


 


Section 3.09           Offer
to Purchase by Application of Excess Proceeds.


 


In the event that, pursuant to Section 4.10
hereof, the Company is required to commence an Asset Sale Offer, it will follow the procedures specified below.


 


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


 


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


 


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


 


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


 


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


 


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


 


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


 


(5)            that
Holders electing to have a Note purchased pursuant to an Asset Sale Offer may elect to have Notes purchased in whole multiples
of $1,000 only;


 


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


 


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


 






    -46-


     


    

 


(8)            that,
if the aggregate principal amount of Notes and other pari passu Indebtedness surrendered by holders thereof exceeds the
Offer Amount, the Company will select the Notes and other pari passu Indebtedness to be purchased on a pro rata basis
based on the principal amount of Notes and such other pari passu Indebtedness surrendered (with such adjustments as may
be deemed appropriate by the Company so that only Notes in minimum denominations of $2,000, or whole multiples of $1,000 in excess

Section 4.01           Payment
of Notes.


 


The Company will pay or cause to be paid
the principal of, premium, if any, and interest, if any, on, the Notes on the dates and in the manner provided in the Notes. Principal
and premium, if any, and interest, if any, will be considered paid on the date due if the Paying Agent, if other than the Company

available funds and designated for and sufficient to pay all principal, premium, if any, and interest then due.


 


The Company will pay interest (including
post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal at the rate equal to 1% per annum in excess
of the then applicable interest rate on the Notes to the extent lawful; it will pay interest (including post-petition interest

Section 4.02          Maintenance
of Office or Agency.


 


The Company will maintain an office or agency
in the continental United States (which may be an office of the Trustee or an affiliate of the Trustee, Registrar or co-registrar)
where Notes may be surrendered for registration of transfer or for exchange and where notices and demands to or upon the Company
in respect of the Notes and this Indenture may be served. The Company will give prompt written notice to the Trustee of the location,
and any change in the location, of such office or agency. If at any time the Company fails to maintain any such required office
or agency or fails 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.


 






    -47-


     


    

 


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 will in any manner relieve
the Company of its obligation to maintain an office or agency in the continental United States for such purposes. The Company will
give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other
office or agency.


 


The Company hereby designates the Corporate
Trust Office of the Trustee as one such office or agency of the Company in accordance with Section 2.03, provided, that such office shall not serve as an office of the Company for purposes of service of legal process on the Company.


 


Section 4.03           Reports.


 


(a)          Whether
or not required by the rules and regulations of the SEC, so long as any Notes are outstanding, the Company will furnish to
the Trustee and, upon request, the Holders of Notes, within the time periods specified in the SEC’s rules and regulations
(after giving effect to any extension or deferral period permitted by the SEC from time to time):


 


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


 


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


 


All such reports will be prepared in all
material respects in accordance with all of the rules and regulations applicable to such reports based on the Company’s
status as an “accelerated filer” or “large accelerated filer” (each as defined in Rule 12b-2 under
the Exchange Act) or as a “non-accelerated filer” (as used in Rule 12b-2 under the Exchange Act), as the case
may be, under the SEC’s rules and regulations. Each annual report on Form 10-K will include a report on the Company’s
consolidated financial statements by the Company’s certified independent accountants. In addition, the Company will file
a copy of each of the reports referred to in clauses (1) and (2) above with the SEC for public availability within the
time periods specified in the rules and regulations applicable to such reports (unless the SEC will not accept such a filing)
and will post the reports on its website as soon as practicable thereafter.


 


If, at any time, the Company is no longer
subject to the periodic reporting requirements of the Exchange Act for any reason, the Company will nevertheless continue filing
the reports specified in this Section 4.03(a) with the SEC within the time periods specified above unless the SEC will
not accept such a filing. 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 this Section 4.03(a) on its website within the time periods that would apply if the Company were
required to file those reports with the SEC.


 


(b)            If
the Company has designated any of its Subsidiaries as Unrestricted Subsidiaries, then the quarterly and annual financial information
required by Section 4.03(a) will include a reasonably detailed presentation, either on the face of the financial statements
or in the footnotes thereto, and in Management’s Discussion and Analysis of Financial Condition and Results of Operations,
of the financial condition and results of operations of the Company and its Restricted Subsidiaries separate from the financial
condition and results of operations of the Unrestricted Subsidiaries of the Company.


 


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


 


(d)            Notwithstanding
the foregoing, the Company will be deemed to have delivered such reports and information referred to above to the Holders and the
Trustee for all purposes of this Indenture if the Company has filed such reports with the SEC via the EDGAR filing system (or any
successor system) and such reports are publicly available. In addition, the requirements of this Section 4.03 will be deemed
satisfied and the Company will be deemed to have delivered such reports and information referred to above to the Trustee for all
purposes of this Indenture by the posting of reports and information that would be required to be provided on the Company’s
website.

(e)            Notwithstanding
the foregoing, in the event that any direct or indirect parent of the Company is or becomes a Guarantor of the Notes, the Company
may satisfy its obligations under this Section 4.03 with respect to financial information relating to the Company by furnishing
financial information relating to such direct or indirect parent; provided that the same is accompanied by consolidating
information that explains in reasonable detail the differences between the information relating to such direct or indirect parent
and any of its Subsidiaries other than the Company and its Restricted Subsidiaries, on the one hand, and the information relating
to the Company, the Guarantors and the other Restricted Subsidiaries of the Company on a standalone basis, on the other hand.


 


(f)            Delivery
of reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such
reports or other documents, as applicable, shall not constitute constructive notice of any information contained therein or determinable
from information contained therein, including the Company’s compliance with any of its covenants under this Indenture (as
to which the Trustee is entitled to rely exclusively on Officer’s Certificates). The Trustee shall not be obligated to monitor
or confirm, on a continuing basis or otherwise, the Company’s or any other Person’s compliance with the covenants described
above or with respect to any reports or other documents filed under this Indenture.


 


Section 4.04           Compliance
Certificate.


 


(a)            The
Company and each Guarantor shall deliver to the Trustee, within 90 days after the end of each fiscal year, an Officer’s Certificate
that need not comply with Section 12.04 stating that a review of the activities of the Company and its Subsidiaries during
the preceding fiscal year has been made under the supervision of the signing Officer with a view to determining whether the Company
has kept, observed, performed and fulfilled its obligations under this Indenture, and further stating, as to each such Officer
signing such certificate, that to his or her knowledge the Company has kept, observed, performed and fulfilled each and every covenant
contained in this Indenture and is not in default in the performance or observance of any of the terms, provisions and conditions
of this Indenture (or, if a Default or Event of Default has occurred, describing all such Defaults or Events of Default of which
he or she may have knowledge and what action the Company is taking or proposes to take with respect thereto) and that to his or
her knowledge no event has occurred and remains in existence by reason of which payments on account of the principal of or interest,
if any, on the Notes is prohibited or if such event has occurred, a description of the event and what action the Company is taking
or proposes to take with respect thereto.


 


(b)            So
long as any of the Notes are outstanding, the Company will deliver to a Responsible Officer of the Trustee, promptly upon any Officer
becoming aware of any Default or Event of Default, an Officer’s Certificate specifying such Default or Event of Default and
what action the Company is taking or proposes to take with respect thereto.


 


Section 4.05           Taxes.


 


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


 


Section 4.06           Stay,
Extension and Usury Laws.


 


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

not cause the Company to not have the funds necessary to pay the principal of or interest on the Notes and (y) such restrictions

provisions which prohibit the payment or making of dividends or other distributions other than on a pro rata basis;

the aggregate, (x) detract from the value of property or assets of the Company or any Restricted Subsidiary in any manner
material to the Company or any Restricted Subsidiary or (y) materially affect the Company’s ability to make future principal

with respect to such dividend and other payment restrictions applicable to such Restricted Subsidiary than those contained in the
agreements covered by clause (1) or (2) of this Section 4.08(b).


 


Section 4.09     Incurrence
of Indebtedness and Issuance of Preferred Stock.


 


(a)           The
Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume,
guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “incur”)
any Indebtedness (including Acquired Debt), and the Company will not issue any Disqualified Stock and will not permit any of its
Restricted Subsidiaries to issue any shares of preferred stock; provided, however, that the Company may incur Indebtedness
(including Acquired Debt) or issue Disqualified Stock and any Restricted Subsidiary may incur Indebtedness (including Acquired
Debt) or issue preferred stock, if the Fixed Charge Coverage Ratio for the Company’s most recently ended four full fiscal
quarters for which internal financial statements are available immediately preceding the date on which such additional Indebtedness
is incurred or such Disqualified Stock or such preferred stock is issued, as the case may be, would have been at least 2.0 to 1.0,
determined on a pro forma basis (including a pro forma application of the net proceeds therefrom), as if the additional Indebtedness
had been incurred or the Disqualified Stock or the preferred stock had been issued, as the case may be, at the beginning of such
four-quarter period; provided further that Restricted Subsidiaries that are not Guarantors
may not incur Indebtedness pursuant to this Section 4.09(a) if, after giving pro forma
effect to such incurrence, the aggregate amount of Indebtedness of Restricted Subsidiaries that are not Guarantors incurred
pursuant to this Section 4.09(a) and clauses (1) and (15) of Section 4.09(b) would exceed 100% of Consolidated
EBITDA for the most recent twelve month period immediately prior to the date of such incurrence.


 


(b)           The
provisions of Section 4.09(a) will not prohibit the incurrence of any of the following items of Indebtedness (collectively,
“Permitted Debt”):


 


(1)              the
incurrence by the Company and any Restricted Subsidiary of Indebtedness and letters of credit and bank guarantees under Credit
Facilities in an aggregate principal amount at any one time outstanding under this clause (1) (with letters of credit and
bank guarantees being deemed to have a principal amount equal to the maximum potential liability of the Company and its Restricted
Subsidiaries thereunder) not to exceed the greater of (a) $1,330.0 million and (b) an amount such that, on a pro
forma basis after giving effect to the incurrence of such Indebtedness (and the application of the net proceeds therefrom),
the Secured Leverage Ratio would be less than 3.75 to 1.00; provided that for purposes
of determining the amount that may be incurred under clause (1)(b), all Indebtedness incurred under clause (1)(b) shall be
deemed to be Secured Indebtedness; provided further that Restricted Subsidiaries that
are not Guarantors may not incur Indebtedness pursuant to this clause (1) if, after giving pro
forma effect to such incurrence, the aggregate amount of Indebtedness of Restricted Subsidiaries that are not Guarantors
incurred pursuant to this clause (1), Section 4.09(a) and clause (15) of this Section 4.09(b) would exceed
100% of Consolidated EBITDA for the most recent twelve month period immediately prior to the date of such incurrence

any part of the purchase price or cost of design, development, construction, installation or improvement of property, plant or
equipment or other assets used or useful in the business of the Company or any of its Restricted Subsidiaries (whether through
the direct purchase of assets or the Capital Stock of any Person owning such assets and whether such Indebtedness is owed to the
seller or Person carrying out such construction or improvement or to any third party) in an aggregate principal amount, including
all Permitted Refinancing Indebtedness incurred to renew, refund, refinance, replace, defease or discharge any Indebtedness incurred
pursuant to this clause (3), not to exceed the greater of (x) $100.0 million and (y) 5.0% of Total Assets at any time
outstanding;


 


(4)              the

Indebtedness) that was permitted by this Indenture to be incurred under Section 4.09(a) or clauses (2), (5), (14) or
(17) of this Section 4.09(b);


 


(5)              the

the Company or any Guarantor is the obligor on such Indebtedness and the payee is not the Company or a Guarantor, such Indebtedness
must be expressly subordinated to the prior payment in full in cash of all Obligations then due with respect to the Notes, in the
case of the Company, or the Note Guarantee, in the case of a Guarantor; and


 


(B)            (B) (i) any
subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than the
Company or a Restricted Subsidiary of the Company and (ii) any sale or other transfer of any such Indebtedness to a Person
that is not either the Company or a Restricted Subsidiary of the Company, will be deemed, in each case, to constitute an incurrence
of such Indebtedness by the Company or such Restricted Subsidiary, as the case may be, that was not permitted by this clause (5);


 


(6)              the
issuance by any of the Company’s Restricted Subsidiaries to the Company or to any of its Restricted Subsidiaries of shares
of preferred stock; provided, however, that:

subsequent issuance or transfer of Equity Interests that results in any such preferred stock being held by a Person other than
the Company or a Restricted Subsidiary of the Company; and


 


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

to the same extent as the Indebtedness guaranteed;

(14)            the

connection with, or in contemplation of, such Person merging into, amalgamating or consolidating with, or becoming a Restricted
Subsidiary of, such Person and (ii) on the date of such acquisition, merger, consolidation or amalgamation after giving pro

representing deferred compensation to employees of the Company and its Subsidiaries incurred in the ordinary course of business.


 


(c)           The
Company will not incur, and will not permit any Guarantor to incur, any Indebtedness (including Permitted Debt) that is contractually
subordinated in right of payment to any other Indebtedness of the Company or such Guarantor unless such Indebtedness is also contractually
subordinated in right of payment to the Notes and the applicable Note Guarantee on substantially identical terms. For all purposes
of the Notes and this Indenture, subordination will refer to contractual payment subordination and not to structural subordination.
The Notes and this Indenture will not treat (1) unsecured Indebtedness as subordinated or junior to Secured Indebtedness merely
because it is unsecured, (2) unsubordinated Indebtedness as subordinated or junior to any other unsubordinated Indebtedness
merely because it has a junior priority with respect to the same collateral or (3) Indebtedness as subordinated or junior
Indebtedness merely because it is structurally subordinated to other Indebtedness.


 


(d)           For
purposes of determining compliance with this Section 4.09, in the event that an item of proposed Indebtedness, Disqualified
Stock or preferred stock meets the criteria of more than one of the categories of Permitted Debt described in clauses (1) through
(24) above, or is entitled to be incurred pursuant to Section 4.09(a) hereof, the Company will be permitted to classify
such item of Indebtedness, Disqualified Stock or preferred stock on the date of its incurrence, or later reclassify all or any
portion of such item of Indebtedness, Disqualified Stock or preferred stock in any manner that complies with this Section 4.09.
Notwithstanding the foregoing, Indebtedness under Credit Facilities that is outstanding on the Issue Date will at all times
be deemed to have been incurred on such date in reliance on the exception provided by clause (1)(a) of the definition of “Permitted
Debt” and may not be reclassified. The accrual of interest, the accretion or amortization of original issue discount, the
payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, the reclassification of preferred
stock as Indebtedness due to a change in accounting principles, and the payment of dividends on Disqualified Stock in the form
of additional shares of the same class of Disqualified Stock will not be deemed to be an incurrence of Indebtedness or an issuance
of Disqualified Stock for purposes of this Section 4.09; provided, in each such case, that the amount of any such accrual,
accretion or payment is included in Fixed Charges of the Company as accrued. Notwithstanding any other provision of this Section 4.09,
the maximum amount of Indebtedness that the Company or any Restricted Subsidiary may incur pursuant to this Section 4.09 shall
not be deemed to be exceeded solely as a result of fluctuations in exchange rates or currency values.


 


(e)            For
purposes of determining compliance with this Section 4.09, in the event that the Company or a Restricted Subsidiary incurs
Indebtedness in connection with a Limited Condition Transaction, the date of determination of the Secured Leverage Ratio or the
Total Leverage Ratio, as applicable, shall, at the option of the Company, be:


 


(1)              the
date that a definitive agreement for such acquisition is entered into and the Secured Leverage Ratio or the Total Leverage Ratio,
as applicable, shall be calculated giving pro forma effect to such acquisition and any actions or transactions related thereto
(including acquisitions, Investments, the Incurrence or issuance of Indebtedness, Disqualified Stock or preferred stock and
the use of proceeds thereof) consistent with the definition of the “Secured Leverage Ratio” or the “Total Leverage
Ratio”, as applicable, and, for the avoidance of doubt, (A) if any such ratios are exceeded as a result of fluctuations
in such ratio (including due to fluctuations in the Consolidated EBITDA of the Company or the target company) at or prior to the
consummation of the relevant acquisition, such ratios will not be deemed to have been exceeded as a result of such fluctuations
solely for purposes of determining whether such acquisition and any related transactions are permitted hereunder and (B) such
ratios shall not be tested at the time of consummation of such Limited Condition Transaction; provided, further, that if the Company
elects to have such determinations occur at the time of entry into such definitive agreement, (i) any such transaction shall
be deemed to have occurred on the date the definitive agreement is entered into and to be outstanding thereafter for purposes of
calculating any ratios under this Indenture after the date of such agreement and before the earlier of the date of consummation
of such acquisition or the date such agreement is terminated or expires without consummation of such acquisition and (ii) to
the extent any covenant baskets were utilized in satisfying any covenants, such baskets shall be deemed utilized until the earlier
of the date of consummation of such acquisition or the date such agreement is terminated or expires without consummation of such
acquisition, but any calculation of Consolidated EBITDA for purposes of other incurrences of Indebtedness or Liens or making of
Restricted Payments (not related to such acquisition) shall not reflect such acquisition until it has been consummated, or


 






    -59-


     


    

 


(2)              the
date such Indebtedness is incurred.


 


(f)            For
purposes of determining compliance with any U.S. dollar-denominated restriction on the incurrence of Indebtedness, the U.S. dollar-equivalent
principal amount of Indebtedness denominated in a foreign currency shall be calculated based on the relevant currency exchange
rate in effect on the date such Indebtedness was incurred, in the case of term debt, or first committed, in the case of revolving
credit debt; provided that if such Indebtedness is incurred to refinance other Indebtedness denominated in a foreign currency,
and such refinancing would cause the applicable U.S. dollar-denominated restriction to be exceeded if calculated at the relevant
currency exchange rate in effect on the date of such refinancing, 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 (i) the principal amount
of such Indebtedness being refinanced plus (ii) the aggregate amount of fees, underwriting discounts, premiums and other costs
and expenses incurred in connection with such refinancing.


 


(g)           The
principal amount of any Indebtedness incurred to refinance other Indebtedness, if incurred in a different currency from the Indebtedness
being refinanced, shall be calculated based on the currency exchange rate applicable to the currencies in which such respective
Indebtedness is denominated that is in effect on the date of such refinancing. The principal amount of any non-interest bearing
Indebtedness or other discount security constituting Indebtedness at any date shall be the principal amount thereof that would
be shown on a balance sheet of the Company dated such date prepared in accordance with GAAP.


 


(h)           For
purposes of calculating any ratio-based basket, with respect to any revolving Indebtedness, delayed draw facility or other committed
debt financing incurred under such ratio-based basket, the Company may elect (which election may be changed with respect to such
Indebtedness upon written notice to the Trustee), at any time, to either (x) give pro forma effect to the incurrence of the
entire committed amount of such Indebtedness as if fully drawn on such date, in which case such committed amount may thereafter
be borrowed or reborrowed, in whole or in part, from time to time, without further compliance with any ratio-based component of
any provision of this Indenture unless the Company changes such election by written notice, or (y) give pro forma effect to
the incurrence of the actual amount drawn under such revolving Indebtedness, delayed draw facility or other committed debt financing,
in which case, the ability to incur the amounts committed to under such Indebtedness will be subject to such ratio-based basket
(to the extent being incurred pursuant to such ratio) at the time of each such incurrence. To the extent clause (x) of the
immediately preceding sentence is elected, such revolving Indebtedness, delayed draw facility or other committed debt financing
shall be deemed to be incurred (and the fully committed amount of Indebtedness as outstanding) at all times thereafter for purposes
of testing any ratio-based baskets, regardless of whether such Indebtedness is outstanding, except to the extent such commitments
have been permanently terminated in full or in part or until the Company has written notice to the Trustee changing its election;
provided that, for the avoidance of doubt, at any time the Company elects clause (x) of the immediately preceding sentence
(including as a result of a change in election), whether such Indebtedness is permitted to be incurred under such ratio-based basket
shall be tested as of the date of such election or change in election, as applicable.


 


Section 4.10     Asset
Sales.


 


(a)           The
Company will not, and will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless:


 


(1)              the
Company (or the Restricted Subsidiary, as the case may be) receives consideration at the time of the Asset Sale at least equal
to the Fair Market Value of the assets or Equity Interests issued or sold or otherwise disposed of; and


 






    -60-

Cash Equivalents. For purposes of this provision, each of the following will be deemed to be cash:


 


(A)            any
liabilities, as shown on the Company’s most recent consolidated balance sheet or in the footnotes thereto (or, if incurred
or accrued subsequent to the date of such balance sheet, such liabilities that would have been reflected on the Company’s
most recent consolidated balance sheet or in the footnotes thereto if such incurrence or accrual had taken place on or prior to
the date of such balance sheet, as determined in good faith by the Company), of the Company or any Restricted Subsidiary (other
than contingent liabilities and liabilities that are by their terms subordinated to the Notes or any Note Guarantee) that are assumed
by the transferee of any such assets and for which the Company or such Restricted Subsidiary has been released in writing;


 


(B)             any
securities, notes or other obligations received by the Company or any such Restricted Subsidiary from such transferee that are
converted by the Company or such Restricted Subsidiary into cash or Cash Equivalents within 180 days of the receipt thereof, to
the extent of the cash or Cash Equivalents received in that conversion;


 


(C)             any
Designated Non-cash Consideration received by the Company or such Restricted Subsidiary in such Asset Sale having an aggregate
fair market value (as determined in good faith by the Company), taken together with all other Designated Non-cash Consideration
received pursuant to this clause (C) that is at that time outstanding, not to exceed the greater of (x) $50.0 million
and (y) 2.5% of Total Assets at the time of the receipt of such Designated Non-cash Consideration, with the Fair Market Value
of each item of Designated Non-cash Consideration being measured at the time received and determined in good faith by the Company
as of the closing of the applicable Asset Sale where such non-cash consideration is received and without giving effect to subsequent
changes in value; and


 


(D)            any
stock or assets of the kind referred to in clause (2) or (4) of Section 4.10(b).


 


(b)           Within
365 days after the receipt of any Net Proceeds from an Asset Sale, the Company (or the applicable Restricted Subsidiary, as the
case may be) may apply such Net Proceeds:


 


(1)              to
prepay, repay or purchase (x) Indebtedness and other Obligations under the Credit Agreement or (y) any other Indebtedness
that is secured; provided that in connection with any prepayment, repayment or purchase of Indebtedness pursuant to this
clause (1), the Company or such Restricted Subsidiary shall retire such Indebtedness and shall cause the related commitment (if
any) to be permanently reduced in an amount equal to the principal amount so prepaid, repaid or purchased;


 


(2)              to
acquire all or substantially all of the assets of, or a majority of the Capital Stock of, another Permitted Business, if, after
giving effect to any such acquisition of Capital Stock, the Permitted Business is or becomes a Restricted Subsidiary of the Company;


 


(3)              to
make a capital expenditure or purchase construction or industrial equipment;


 


(4)              to
acquire or license other assets (other than Capital Stock) and that are used or useful in a Permitted Business;


 


(5)              to
acquire Replacement Assets; or


 


(6)              to
repay Indebtedness of a Restricted Subsidiary that is not a Guarantor, other than Indebtedness owed to the Company or another Restricted
Subsidiary;


 






    -61-


     


    

 


provided that in the case of clause (2), (3), (4) or
(5) above, a binding commitment shall be treated as a permitted application of the Net Proceeds from the date of such commitment
so long as the Company or such other Restricted Subsidiary enters into such commitment with a good faith expectation that such
Net Proceeds will be applied to satisfy such commitment within 180 days of such commitment (an “Acceptable Commitment”);
and provided, further, that if any Acceptable Commitment is later terminated or cancelled before such Net Proceeds are applied,
then such Net Proceeds shall constitute Excess Proceeds (as defined below) if not otherwise applied as provided above within 365
days of the receipt of such Net Proceeds.


 


(c)           Pending
the final application of any Net Proceeds, the Company may temporarily reduce revolving credit borrowings or otherwise invest the
Net Proceeds in any manner that is not prohibited by this Indenture.


 


(d)           Notwithstanding
the foregoing, to the extent that (i) any of or all the Net Proceeds from any Asset Sale by a Foreign Subsidiary (a “Foreign
Disposition”) is prohibited or delayed by applicable local law from being repatriated to the United States
or (ii) the Company, in its sole discretion, has determined in good faith that repatriation of any of or all of the Net Proceeds
of any Foreign Disposition would result in material adverse tax consequences, the portion of such Net Proceeds so affected will
not be required to be applied in compliance with this covenant; provided that within 365 days of the receipt of the Net Proceeds
of any Foreign Disposition, the Company shall use commercially reasonable efforts to permit repatriation of such proceeds that
would otherwise be subject to this covenant without violating applicable local law or incurring material adverse tax consequences,
and, if such proceeds may be repatriated, within such 365 day period, such proceeds shall be applied in compliance with this covenant.


 


(e)           Any
Net Proceeds from Asset Sales that are not applied or invested as described above will constitute “Excess Proceeds.”
When the aggregate amount of Excess Proceeds exceeds $100.0 million, within 30 days thereof, unless waived or modified with the
consent of the Holders of at least a majority in aggregate principal amount of the Notes then outstanding, the Company will make
an offer (an “Asset Sale Offer”) to the Holders of Notes (with a copy to the Trustee) and all holders
of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in this Indenture
with respect to offers to purchase or redeem with the proceeds of sales of assets in accordance with Section 3.09 to purchase
the maximum principal amount of Notes and such other pari passu Indebtedness that may be purchased out of the Excess Proceeds.
The offer price in any Asset Sale Offer will be equal to 100% of the principal amount plus accrued and unpaid interest,
if any, to the date of purchase, and will be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale
Offer, the Company may use those Excess Proceeds for any purpose not otherwise prohibited by this Indenture. If the aggregate principal
amount of Notes and other pari passu Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds,
the Company will select the Notes and such other pari passu Indebtedness to be purchased on a pro rata basis. Upon
completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero.


 


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


 


Section 4.11     Transactions
with Affiliates.


 


(a)            The
Company will not, and will not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise
dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction,
contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate of the Company (each,
an “Affiliate Transaction”) involving aggregate payments or consideration in excess of $25.0 million,
unless:


 






    -62-


     


    

 


(1)              the
Affiliate Transaction is on terms that, when taken as a whole, are not materially less favorable to the Company or the relevant
Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary
with an unrelated Person; and


 


(2)              the
Company delivers to the Trustee with respect to any Affiliate Transaction or series of related Affiliate Transactions involving
aggregate consideration in excess of $50.0 million, a resolution of the Board of Directors of the Company set forth in an Officer’s
Certificate certifying that such Affiliate Transaction complies with clause (1) of this Section 4.11(a) and that
such Affiliate Transaction has been approved by a majority of the disinterested members of the Board of Directors of the Company.


 


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


 


(1)              any
employment agreement, employee benefit plan, indemnification agreement or arrangement for directors, officers, employees, agents
and consultants, stock option, stock repurchase agreement, consulting agreement, severance agreement, insurance plan or any similar
agreement, plan or arrangement, in each case entered into by the Company or any of its Restricted Subsidiaries in the ordinary
course of business and payments pursuant thereto;


 


(2)              transactions
between or among the Company and/or its Restricted Subsidiaries;


 


(3)              transactions
with a Person (other than an Unrestricted Subsidiary of the Company) 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 directors’ fees; provided that the aggregate fees paid or payable in any calendar year to any director
who is an Affiliate of the Company in a capacity other than as a director of the Company shall not be greater than the aggregate
fees paid or payable in such year to any other director who is not otherwise an Affiliate of the Company;


 


(5)              any
issuance of Equity Interests (other than Disqualified Stock) of the Company to Affiliates, directors, officers or employees of
the Company or its Restricted Subsidiaries or to holders of Equity Interests in the Company;


 


(6)              the
issuances of securities or other payments, awards or grants in cash, securities or otherwise pursuant to, or the funding of, employment
arrangements, stock option, stock ownership, severance or termination plans and similar employee benefit agreements, arrangements
or plans approved by the Board of Directors of the Company and entered into by the Company or any of its Restricted Subsidiaries
in the ordinary course of business or consistent with past practices and advances, reimbursements and payments pursuant thereto;


 


(7)              Restricted
Payments and Permitted Investments that do not violate Section 4.07 hereof;


 


(8)              loans
and advances paid (and cancellation of loans and advances) to officers, directors or employees of the Company or any of its Restricted
Subsidiaries in the ordinary course of business in accordance with past practice of the Company or such Restricted Subsidiary;


 


(9)              transactions
entered into after the Reversion Date pursuant to a contract, agreement, loan, advance or guaranty with, or for the benefit of,
any Affiliate of the Company entered into during the Suspension Period, or as the same may be amended, modified or replaced from
time to time so long as any such amendment, modification or replacement is not materially less favorable to the Company or the
Holders of Notes than the applicable contract, agreement, loan, advance or guaranty entered into during the Suspension Period;


 






    -63-


     


    

 



 


(10)        transactions
with Affiliates that are customers, suppliers, contractors, joint venture partners or purchasers or sellers of goods or services,
in each case which are in the ordinary course of business and otherwise in compliance with the terms of this Indenture, and which
are fair to the Company and its Restricted Subsidiaries, as applicable, in the reasonable determination of the Board of Directors,
chief executive officer or chief financial officer of the Company or its Restricted Subsidiaries, as applicable, or are on terms
that, taken as a whole, are materially not less favorable to the Company or such Restricted Subsidiary than could reasonably be
obtained, at the time of such transaction or, if such transaction is pursuant to a written agreement, at the time of the execution
of the agreement providing therefor, in a comparable arm’s-length transaction with a Person that is not an Affiliate;


 


(11)        transactions
permitted under Section 5.01 hereof;


 


(12)        transactions
between the Company or any of its Restricted Subsidiaries and any Person that is an Affiliate of the Company or any of its Restricted
Subsidiaries solely because a director of such Person is also a director of the Company; provided, however, that such director
abstains from voting as a director on any matter involving such other Person; and


 


(13)        transactions
with any Person solely in its capacity as a holder of Indebtedness or Capital Stock of the Company or any of its Restricted Subsidiaries
if such transaction provides for equal treatment of such Person and all other holders, in their capacity as holders, of the same
series of such Indebtedness or of the same class of such Capital Stock;


 


(14)        transactions
permitted under Section 4.09.


 


Section 4.12         Liens.


 


(a)            The
Company will not, and will not permit any of its Restricted Subsidiaries to, create, incur, assume or otherwise cause or suffer
to exist or become effective any Lien of any kind upon any of their property or assets securing Indebtedness, now owned or hereafter
acquired, unless all payments due under this Indenture and the Notes are secured on an equal and ratable basis with the obligations
so secured until such time as such obligations are no longer secured by a Lien. Any Lien created for the benefit of the holders
of Notes pursuant to the preceding sentence shall provide that such Lien shall be automatically and unconditionally released upon
the release of the other Lien referred to in the preceding sentence. The foregoing shall not apply to:


 


(1)          Liens
to secure Indebtedness permitted to be incurred under Section 4.09; provided that, in the case of this clause (1),
at the time of incurrence and after giving pro forma effect thereto, the Secured Leverage Ratio shall not exceed 3.50 to
1.00; and


 


(2)          Permitted
Liens.


 


For purposes of determining compliance with this Section 4.12,
(x) a Lien need not be incurred solely by reference to one category of Permitted Liens or one category of permitted Liens
described in the proviso to clause (1) above but may be incurred under any combination of such categories (including in part
under one such category and in part under any one or more of such other such categories) and (y) in the event that a Lien
(or any portion thereof) meets the criteria of one or more of such categories, the Company, in its sole discretion, may divide
and/or classify, or at any later time re-divide and/or reclassify, such Lien (or any portion thereof) in any manner that complies
with this Section 4.12 and the definition of “Permitted Liens”. Notwithstanding the foregoing, any Lien under
Credit Facilities that is outstanding on the Issue Date will at all times be deemed to have been incurred on such date in reliance
on the exception provided by clause (1) of the definition of “Permitted Liens” and may not be reclassified.

Section 4.14        Corporate
Existence.


 


Subject to Article V, the Company shall
do or cause to be done all things necessary to preserve and keep in full force and effect:


 


(1)          its
corporate existence, and the corporate, partnership or other existence of each of its Subsidiaries, in accordance with the respective
organizational documents (as the same may be amended from time to time) of the Company or any such Subsidiary; and


 


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


 


Section 4.15        Offer
to Repurchase Upon Change of Control.


 


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


 


(1)          that
the Change of Control Offer is being made pursuant to this Section 4.15 and that all Notes properly tendered and not withdrawn
will be accepted for payment;


 


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


 


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


 


(4)          that,
unless the Company defaults in the payment of the Change of Control Payment, all Notes accepted for payment pursuant to the Change
of Control Offer will cease to accrue interest 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 will be required to surrender the Notes, with
the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer by book-entry transfer,
to the Paying Agent at the address specified in the notice prior to the close of business on the third 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, a 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 his election to have the
Notes purchased; and


 






    -65-


     


    

 


(7)          that
Holders whose Notes are being purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion
of the Notes surrendered, which unpurchased portion must be equal to $2,000 in principal amount or an integral multiple of $1,000
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 those laws and
regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control. To the extent that
the provisions of any securities laws or regulations conflict with the provisions of Section 3.09 or 4.15, the Company will
comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under Section 3.09
or 4.15 by virtue of such compliance.


 


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


 


(1)            accept
for payment all Notes or portions of Notes properly 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 of Notes properly tendered;
and


 


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


 


The Paying Agent will promptly deliver to
each Holder of Notes properly tendered the Change of Control Payment for such Notes, and the Trustee will promptly authenticate
and deliver (or cause to be transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased portion
of the Notes surrendered, if any; provided that each new Note will be in a principal amount of $2,000 or an integral multiple
of $1,000 in excess thereof. Any Notes so accepted for payment will cease to accrue interest on and after the Change of Control
Payment Date. The Company will publicly announce the results of the Change of Control Offer on or as soon as practicable after
the Change of Control Payment Date.


 


(c)            Notwithstanding
anything to the contrary in this Section 4.15, the Company may make a Change of Control Offer prior to the consummation of
a Change of Control, and conditioned on the occurrence of such Change of Control, if a definitive agreement is in place for such
Change of Control at the time the Company makes such Change of Control Offer. In such case, the notice described in Section 4.15(a) shall
state that the Change of Control Offer is conditioned on the Change of Control being consummated on or prior to the Change of Control
Payment Date.


 


(d)            Notwithstanding
anything to the contrary in this Section 4.15, the Company will not be required to make a Change of Control Offer upon a Change
of Control if (1) a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance
with the requirements set forth in this Section 4.15 and purchases all Notes properly tendered and not withdrawn under the
Change of Control Offer, (2) notice of redemption has been given pursuant to Section 3.07, unless and until there is
a default in payment of the applicable redemption price, or (3) the requirements set forth in this Section 4.15 are waived
or modified with the consent of the Holders of a majority in aggregate principal amount of Notes then outstanding.


 


(e)            In
the event that Holders of Notes of not less than 90% of the aggregate principal amount of the outstanding Notes accept a Change
of Control Offer and the Company purchases all of the Notes held by such Holders, within 90 days of such purchase, the Company
will have the right, upon not less than 15 days’ nor more than 60 days’ prior notice, to redeem all of the Notes that
remain outstanding following such purchase at a redemption price equal to the Change of Control Payment plus, to, but excluding,
the extent not included in the Change of Control Payment, accrued and unpaid interest, if any, on the Notes redeemed, to the applicable
redemption date, (subject to the right of Holders of record on the relevant record date to receive interest due on an interest
payment date falling on or prior to such redemption date).

Section 4.17         [Reserved]


 


Section 4.18         Additional
Note Guarantees.


 


The Company shall cause each Restricted
Subsidiary that guarantees Indebtedness of the Company under any Credit Facility to become a Guarantor and execute a supplemental
indenture substantially in the form of supplemental indenture appearing as an exhibit to this Indenture and deliver an Opinion
of Counsel within 30 days of the date on which it became a guarantor of borrowings of the Company under any Credit Facility. The
form of such supplemental indenture is attached as Exhibit E hereto.


 


Section 4.19        Designation
of Restricted and Unrestricted Subsidiaries.


 


The Board of Directors of the Company may
designate any Restricted Subsidiary to be an Unrestricted Subsidiary; provided that:


 


(a)            such
designation would not cause a Default or Event of Default;


 


(b)            the
aggregate Fair Market Value of all outstanding Investments owned by the Company and its Restricted Subsidiaries in the Subsidiary
designated as unrestricted will be deemed to be an Investment made as of the time of the designation and will reduce the amount
available for Restricted Payments under Section 4.07 or under one or more clauses of the definition of “Permitted Investments,”
as determined by the Company; provided, further, that such designation will only be permitted if the Investment would
be permitted at that time; and


 


(c)            such
designation otherwise meets the definition of “Unrestricted Subsidiary.”


 


Any designation of a Subsidiary of the Company
as an Unrestricted Subsidiary will be evidenced to the Trustee by filing with the Trustee a certified copy of a resolution of the
Board of Directors giving effect to such designation and an Officer’s Certificate certifying that such designation complied
with the preceding conditions and was permitted by Section 4.07 hereof. If, at any time, any Unrestricted Subsidiary would
fail to meet the preceding requirements as an Unrestricted Subsidiary, it will thereafter cease to be an Unrestricted Subsidiary
for purposes of this Indenture and any Indebtedness of such Subsidiary will be deemed to be incurred by a Restricted Subsidiary
of the Company as of such date and, if such Indebtedness is not permitted to be incurred as of such date under Section 4.09
hereof, the Company will be in Default of such covenant. The Board of Directors of the Company may at any time designate any Unrestricted
Subsidiary to be a Restricted Subsidiary by delivery to the Trustee of an Officer’s Certificate setting forth such designation;
provided that such designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of the Company
of any outstanding Indebtedness of such Unrestricted Subsidiary and such designation will only be permitted if: (1) such Indebtedness
is permitted under Section 4.09 hereof, calculated on a pro forma basis as if such designation had occurred at the beginning
of the four-quarter reference period; and (2) no Default or Event of Default would be in existence following such designation.


 


The designation of any Person as an Unrestricted
Subsidiary shall be deemed to include a designation of all Subsidiaries of such Person as Unrestricted Subsidiaries.


 


Any designation of a Subsidiary of the Company
as a Restricted Subsidiary will be evidenced to the Trustee by filing with the Trustee a certified copy of a resolution of the
Board of Directors giving effect to such designation and an Officer’s Certificate certifying that such designation complied
with the preceding conditions and was permitted by this Indenture.


 


Section 4.20         Covenant
Suspension.


 


If, on any date, (i) the Notes have
Investment Grade Ratings from both Rating Agencies, and (ii) no Default has occurred and is continuing under this Indenture
(the occurrence of the events described in the foregoing clauses (i) and (ii) being collectively referred to as a “Covenant
Suspension Event”) then, beginning on that day and continuing at all times thereafter until the Reversion Date (as
defined below), the restrictions described in Sections 4.07, 4.08, 4.09, 4.10, 4.11 and 5.01(4) shall no longer be applicable
to the Notes (collectively, the “Suspended Covenants”).


 






    -67-


     


    

 


In the event that the Company and the Restricted
Subsidiaries are not subject to the Suspended Covenants under this Indenture for any period of time as a result of the foregoing,
and on any subsequent date (the “Reversion Date”) one or both of the Rating Agencies withdraw their Investment
Grade Rating or downgrade the rating assigned to the Notes below an Investment Grade Rating, then the Company and the Restricted
Subsidiaries will thereafter again be subject to the Suspended Covenants under this Indenture with respect to future events. The
period of time between the Covenant Suspension Event and the Reversion Date is referred to in this description as the “Suspension
Period.”


 


On each Reversion Date, all Indebtedness
incurred, or Disqualified Stock or preferred stock issued, during the preceding Suspension Period will be classified as having
been incurred or issued pursuant to Section 4.09(b)(2). Calculations made after the Reversion Date of the amount available
to be made as Restricted Payments in Section 4.07 will be made as though the covenant described in Section 4.07 had been
in effect prior to, and during, the Suspension Period. As described above, no Default or Event of Default will be deemed to have
occurred on the Reversion Date as a result of any actions taken or omitted to be taken by the Company or the Restricted Subsidiaries
during the Suspension Period. On and after each Reversion Date, the Company and its Subsidiaries shall be permitted to consummate
the transactions contemplated by any contract entered into during the Suspension Period so long as such contract and such consummation
would have been permitted during such Suspension Period.


 


For purposes of Section 4.08, on the
Reversion Date, any consensual encumbrances or restrictions of the type specified in Section 4.08 (a)(1), (2) or (3) entered
into during the Suspension Period will be deemed to have been in effect on the date of this Indenture, so that they are permitted
under Section 4.08(b)(1).


 


For purposes of Section 4.10, on the
Reversion Date, the unutilized Excess Proceeds amount will be reset to zero. During a Suspension Period, the Company may not designate
any of its Subsidiaries as Unrestricted Subsidiaries.


 


The Company shall deliver an Officer’s
Certificate to the Trustee notifying the Trustee of the commencement of any Suspension Period or the occurrence of any Reversion
Date promptly after such commencement or occurrence, as the case may be, and the Trustee shall have no obligation to monitor or
determine whether a Suspension Period or a Reversion Date has occurred or exists.

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 had been named as the Company herein; provided, however,
that the predecessor Company shall not be relieved from the obligation to pay the principal of and interest on the Notes except
in the case of a sale of all of the Company’s assets in a transaction that is subject to, and that complies with the provisions
of, Section 5.01.

for relief against the Company or any of its Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted
Subsidiaries that, taken together (as of the date of the latest audited consolidated financial statements for the Company), would
constitute a Significant Subsidiary, in a proceeding in which the Company, any such Restricted Subsidiary that is a Significant
Subsidiary or any such group of Restricted Subsidiaries that, taken together (as of the date of the latest audited consolidated
financial statements for the Company), would constitute a Significant Subsidiary, is to be adjudicated bankrupt or insolvent;


 


(B)            appoints
a receiver, liquidator, assignee, trustee, sequestrator or other similar official of the Company or any of its Restricted Subsidiaries

consolidated financial statements for the Company), would constitute a Significant Subsidiary, or for all or substantially all
of the property of the Company, any of its Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted
Subsidiaries that, taken together (as of the date of the latest audited consolidated financial statements for the Company), would

(C)            orders
the liquidation of the Company, any of its Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted
Subsidiaries that, taken together (as of the date of the latest audited consolidated financial statements for the Company), would
constitute a Significant Subsidiary;


 


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


 


(b)            Any
notice of Default or Event of Default, notice of acceleration or instruction to the Trustee to provide a notice of Default or Event
of Default, notice of acceleration or take any other action (a “Noteholder Direction”) provided by any
one or more Holders of the Notes (other than a Regulated Bank) (each a “Directing Holder”) must be accompanied
by a written representation from each such Directing Holder to the Company and the Trustee that such Directing Holder is not (or,
in the case such Directing Holder is DTC or its nominee, that such Directing Holder is being instructed solely by beneficial owners
that have represented to such Directing Holder that they are not) Net Short (a “Position Representation”),
which representation, in the case of a Noteholder Direction relating to the delivery of a notice of Default or Event of Default
shall be deemed repeated at all times until the resulting Default or Event of Default is cured or otherwise ceases to exist or
the Notes are accelerated. In addition, each Directing Holder must at the time of providing a Noteholder Direction covenant, provide
the Company with such other information as the Company may reasonably request from time to time in order to verify the accuracy
of such Noteholder’s Position Representation within five Business Days of request therefor (a “Verification Covenant”).
In any case in which the Directing Holder is DTC or its nominee, any Position Representation or Verification Covenant required
hereunder shall be provided by the beneficial owner of the Notes in lieu of DTC or its nominee.


 


If, following the delivery of a Noteholder
Direction, but prior to acceleration of the Notes, the Company determines in good faith that there is a reasonable basis to believe
a Directing Holder was, at any relevant time, in breach of its Position Representation and provides to the Trustee an Officer’s
Certificate stating that the Company has initiated litigation with a court of competent jurisdiction seeking a determination that
such Directing Holder was, at such time, in breach of its Position Representation, and seeking to invalidate any Default or Event
of Default that resulted from the applicable Noteholder Direction, the cure period with respect to such Default or Event of Default
shall be automatically stayed and the cure period with respect to such Default or Event of Default shall be automatically reinstituted
and any remedy stayed pending a final and non-appealable determination of a court of competent jurisdiction on such matter. If,
following the delivery of a Noteholder Direction, but prior to acceleration of the Notes, the Company provides to the Trustee an
Officer’s Certificate stating that a Directing Holder failed to satisfy its Verification Covenant, the cure period with respect
to such Default or Event of Default shall be automatically stayed and the cure period with respect to any Default or Event of Default
that resulted from the applicable Noteholder Direction shall be automatically reinstituted and any remedy stayed pending satisfaction
of such Verification Covenant. Any breach of the Position Representation shall result in such Holder’s participation in such
Noteholder Direction being disregarded; and, if, without the participation of such Holder, the percentage of Notes held by the
remaining Holders that provided such Noteholder Direction would have been insufficient to validly provide such Noteholder Direction,
such Noteholder Direction shall be void ab initio, with the effect that such Default or Event of Default shall be deemed never
to have occurred, acceleration voided and the Trustee shall be deemed not to have received such Noteholder Direction or any notice
of such Default or Event of Default.


 






    -71-


     


    

 


Notwithstanding anything in this Section 6.01(b) to
the contrary, any Noteholder Direction delivered to the Trustee during the pendency of an Event of Default as the result of a bankruptcy
or similar proceeding shall not require compliance with the foregoing paragraphs. In addition, for the avoidance of doubt, the
foregoing paragraphs shall not apply to any Holder that is a Regulated Bank.


 


For the avoidance of doubt, the Trustee
shall be entitled to conclusively rely on any Noteholder Direction delivered to it in accordance with this Indenture, shall have
no duty to inquire as to or investigate the accuracy of any Position Representation, enforce compliance with any Verification Covenant,
verify any statements in any Officer’s Certificate delivered to it, or otherwise make calculations, investigations or determinations
with respect to Derivative Instruments, Net Shorts, Long Derivative Instruments, Short Derivative Instruments or otherwise. The
Trustee shall have no liability to the Company, any holder or any other Person in acting in good faith on a Noteholder Direction.


 


(c)            Any
Default or Event of Default for the failure to comply with the time periods prescribed in Section 4.03 or otherwise to deliver
any notice or certificate pursuant to any other provision of this Indenture shall be deemed to be cured upon the delivery of any
such report required by such covenant or such notice or certificate, as applicable, even though such delivery is not within the
prescribed period specified in this Indenture. Any time period in this Indenture to cure any actual or alleged Default or Event
of Default may be extended or stayed by a court of competent jurisdiction to the extent such actual or alleged Default or Event
of Default is the subject of litigation.


 


Section 6.02         Acceleration.


 


In the case of an Event of Default specified
in clause (9) or (10) of Section 6.01 hereof, with respect to the Company, any Restricted Subsidiary of the Company
that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Company that, taken together, would constitute
a Significant Subsidiary, all outstanding Notes will become due and payable immediately without further action or notice. If any
other Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the
then outstanding Notes may declare all the Notes to be due and payable immediately; provided, that a notice of a Default
or Event of Default may not be given with respect to any action taken, and reported publicly or to Holders, more than two years
prior to such notice of Default or Event of Default. If an Event of Default arises pursuant to clause (6) of Section 6.01
hereof, such Event of Default shall cease to exist if, at any time prior to the acceleration of the Notes, (x) the Company
cures the underlying Payment Default or the Holders of the applicable Indebtedness waive the underlying Payment Default or rescind
the acceleration of such Indebtedness, in each case in accordance with the terms of the applicable Indebtedness and (y) the
cure, waiver or rescission does not conflict with any judgment or decree of a court of competent jurisdiction.


 


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


 






    -72-


     


    

 


The Holders of a majority in aggregate principal
amount of the then outstanding Notes by notice to the Trustee may, on behalf of the Holders of all of the Notes, rescind an acceleration
provided all amounts owing to the Trustee have been paid or waive any existing Default or Event of Default (except a continuing
Default or Event of Default in the payment of interest or premium, if any, on, or the principal of, the Notes) and its consequences
under this Indenture, if:


 


(1)          such
rescission or waiver would not conflict with any judgment or decree of a court of competent jurisdiction;


 


(2)          all
existing Events of Default, except nonpayment of principal or interest that has become due solely because of the acceleration,
have been cured or waived;


 


(3)          all
interest on overdue installments of interest and overdue principal, which has become due otherwise than by such declaration of
acceleration, has been paid, to the extent the payment of such interest is lawful; and


 


(4)          the
Company has paid the Trustee its reasonable compensation and reimbursed the Trustee for its reasonable expenses (including the
fees and expenses of its counsel), disbursements and advances.


 


Section 6.03         Other
Remedies.


 


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


 


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


 


Section 6.04         Waiver
of Past Defaults.


 


Holders of not less than a majority in aggregate
principal amount of the then outstanding Notes by notice to the Trustee may on behalf of the Holders of all of the Notes waive
an existing Default or Event of Default and its consequences hereunder, except a continuing Default or Event of Default in the
payment of the principal of, premium, if any, or interest on, the Notes (including in connection with an offer to purchase); provided,
however, that the Holders of a majority in aggregate principal amount of the then outstanding Notes may rescind an acceleration
and its consequences, including any related payment default that resulted from such acceleration.


 


Section 6.05         Control
by Majority.


 


Holders of a majority in aggregate principal
amount of the then outstanding Notes may direct the time, method and place of conducting any proceeding for exercising any remedy
available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction
that conflicts with law or this Indenture, that the Trustee determines in its sole discretion may be unduly prejudicial to the
rights of other Holders of Notes (it being understood that the Trustee does not have an affirmative duty to ascertain whether or
not any such directions are unduly prejudicial to such Holders), or that may involve the Trustee in personal liability. The Trustee
may take any other action deemed proper by the Trustee which is not inconsistent with such direction.


 


Section 6.06          Limitation
on Suits.


 


A Holder may pursue a remedy with respect
to this Indenture or the Notes only if:


 


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


 






    -73-


     


    

 


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


 


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


 


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


 


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


 


A Holder of a Note may not use this Indenture
to prejudice the rights of another Holder of a Note or to obtain a preference or priority over another Holder of a Note.


 


Section 6.07         Rights
of Holders of Notes to Receive Payment.


 


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


 


Section 6.08         Collection
Suit by Trustee.


 


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


 


Section 6.09         Trustee
May File Proofs of Claim.


 


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

law.


 


Section 7.05     Notice
of Defaults.


 


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

Section 7.06     [Reserved].


 


Section 7.07     Compensation
and Indemnity.


 


(a)            The
Company will pay to the Trustee from time to time compensation for its acceptance of this Indenture and services hereunder which
shall have from time to time been separately agreed to by the Company and the Trustee in writing. The Trustee’s compensation
will not be limited by any law on compensation of a trustee of an express trust. The Company will reimburse the Trustee promptly
upon request for all reasonable disbursements, advances and expenses incurred or made by it in addition to the compensation for
its services. Such expenses will include the reasonable compensation, disbursements and expenses of the Trustee’s agents,
attorneys, accountants, experts and other professionals as the Trustee deems necessary, advisable or appropriate.


 


(b)            The
Company and the Guarantors, jointly and severally, will indemnify the Trustee, and hold it harmless, against any and all losses,
claims, damages, liabilities, fees, costs or expenses incurred by it arising out of or in connection with this Indenture and the
acceptance or administration of its duties under this Indenture, including the costs and expenses, reasonable attorneys’
fees and expenses and court costs of enforcing this Indenture against the Company and the Guarantors (including this Section 7.07)
and defending itself against or investigating any claim (whether asserted by the Company, the Guarantors, any Holder or any other
Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, except to the extent
any such loss, liability or expense is determined by a court of competent jurisdiction in a final non-appealable order to have
been caused by its own negligence or willful misconduct. The Trustee will notify the Company in writing promptly of any claim for
which it may seek indemnity. Failure by the Trustee to so notify the Company will not relieve the Company or any of the Guarantors
of their obligations hereunder. The Company or such Guarantor will defend the claim and the Trustee will cooperate in the defense.
The Trustee may have separate counsel and the Company will pay the reasonable fees and expenses of such counsel. Neither the Company
nor any Guarantor need pay for any settlement made without its consent, which consent will not be unreasonably withheld. All indemnifications
and releases from liability granted hereunder to the Trustee shall extend to its officers, directors, employees, agents, attorneys,
custodians, successors and assigns.


 


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


 


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


 


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


 


(f)            “Trustee”
for the purposes of this Section 7.07 shall include any predecessor Trustee and the Trustee in each of its capacities hereunder
and each agent, custodian and other person employed to act hereunder; provided, however, that the negligence or willful misconduct
of any Trustee hereunder shall not affect the rights of any other Trustee hereunder.


 


Section 7.08     Replacement
of Trustee.


 


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


 


(b)            The
Trustee may resign in writing at any time on 30 days’ prior written notice and be discharged from the trust hereby created
by so notifying the Company. The Holders of a majority in aggregate principal amount of the then outstanding Notes may remove the
Trustee on 30 days’ prior written notice by so notifying the Trustee and the Company in writing. The Company may remove the
Trustee if:


 






    -78-


     


    

 


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


 


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


 


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


 


(4)            the
Trustee becomes incapable of acting.


 


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


 


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


 


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


 


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


 


Notwithstanding replacement of the Trustee
pursuant to this Section 7.08, the Company’s obligations under Section 7.07 will continue for the benefit of the
retiring Trustee.


 


Section 7.09     Successor
Trustee by Merger, etc.


 


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


 


Section 7.10     Eligibility;
Disqualification.


 


There will at all times be a Trustee hereunder
that is a corporation organized and doing business under the laws of the United States of America or of any state thereof that
is authorized under such laws to exercise corporate trustee power, that is subject to supervision or examination by federal or
state authorities and that has (or, in the case of a Trustee included in a bank holding company system, the related bank holding
company has) a combined capital and surplus of at least $50.0 million as set forth in its most recent published annual report of
condition.


 


ARTICLE VIII


LEGAL DEFEASANCE
AND COVENANT DEFEASANCE


 


Section 8.01     Option
to Effect Legal Defeasance or Covenant Defeasance.


 


The Company may at any time, at the option
of its Board of Directors evidenced by a resolution set forth in an Officer’s Certificate delivered to the Trustee, elect
to have either Section 8.02 or 8.03 be applied to all outstanding Notes and Note Guarantees upon compliance with the conditions
set forth below in this Article VIII.


 






    -79-


     


    

 


Section 8.02     Legal
Defeasance and Discharge.


 


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


 


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


 


(2)            the
Company’s obligations with respect to such Notes under Article II and Section 4.02;


 


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


 


(4)            this
Article VIII.


 


Subject to compliance with this Article VIII,
the Company may exercise its option under this Section 8.02 notwithstanding the prior exercise of its option under Section 8.03.


 


Section 8.03     Covenant
Defeasance.


 


Upon the Company’s exercise under
Section 8.01 of the option applicable to this Section 8.03, the Company and each of the Guarantors will, subject to the
satisfaction of the conditions set forth in Section 8.04, be released from each of their obligations under the covenants contained
in Sections 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.15, 4.16, 4.17, 4.18 and 4.19 and clause (4) of Section 5.01
with respect to the outstanding Notes on and after the date the conditions set forth in Section 8.04 are satisfied (hereinafter,
“Covenant Defeasance”), and the Notes will thereafter be deemed not “outstanding” for the
purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection
with such covenants, but will continue to be deemed “outstanding” for all other purposes hereunder (it being understood
that such Notes will not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with
respect to the outstanding Notes and Note Guarantees, the Company and the Guarantors may omit to comply with and will have no liability
in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any
reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein
or in any other document and such omission to comply will not constitute a Default or an Event of Default under Section 6.01,
but, except as specified above, the remainder of this Indenture and such Notes and Note Guarantees will be unaffected thereby.
In addition, upon the Company’s exercise under Section 8.01 of the option applicable to this Section 8.03, subject
to the satisfaction of the conditions set forth in Section 8.04, Sections 6.01(3) through 6.01(6) will not constitute
Events of Default.


 


Section 8.04     Conditions
to Legal or Covenant Defeasance.

or Covenant Defeasance under either Section 8.02 or 8.03 hereof:

Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders, cash in U.S. dollars, non-callable
Government Securities, or a combination of cash in U.S. dollars and non-callable Government Securities, in amounts as will be sufficient,
in the opinion of a nationally recognized investment bank, appraisal firm or firm of independent public accountants, to pay the
principal of, or interest and premium, if any, on, the outstanding Notes on the stated date for payment thereof or on the applicable
redemption date, as the case may be, and the Company must specify whether the Notes are being defeased to such stated date for
payment or to a particular redemption date;


 


(2)            in
the case of an election under Section 8.02, the Company must deliver to the Trustee an Opinion of Counsel reasonably satisfactory
to the Trustee confirming that (A) the Company has received from, or there has been published by, the Internal Revenue Service
a ruling or (B) since the date of this Indenture, there has been a change in the applicable U.S. federal income tax law, in
either case to the effect that, and based thereon such Opinion of Counsel will confirm that, the 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;


 


(3)            in
the case of an election under Section 8.03, the Company must deliver to the Trustee an Opinion of Counsel reasonably acceptable
to the Trustee confirming that the 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;


 


(4)            no
Default has occurred and is continuing on the date of such deposit (other than a Default resulting from the borrowing of funds
to be applied to such deposit) 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 Guarantor is a party or by which the Company or any Guarantor is bound;


 


(5)            such
Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under, any material
agreement or instrument (other than this Indenture) to which the Company or any of its Subsidiaries is a party or by which the
Company or any of its Subsidiaries is bound;


 


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


 


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


 


Section 8.05     Deposited
Money and Government Securities To Be Held in Trust; Other Miscellaneous Provisions.


 


(a)            Subject
to Section 8.06, all money and non-callable Government Securities (including the proceeds thereof) deposited with the Trustee
(or other qualifying trustee, collectively for purposes of this Section 8.05, the “Trustee”) pursuant
to Section 8.04 in respect of the outstanding Notes will be held in trust and applied by the Trustee, in accordance with the
provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (other than the Company)
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.


 


(b)            The
Company will pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or non-callable
Government Securities deposited pursuant to Section 8.04 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.


 






    -81-


     


    

 


(c)            Notwithstanding
anything in this Article VIII to the contrary, the Trustee will 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 8.04 which, in the opinion
of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the
Trustee (which may be the opinion delivered under Section 8.04(1)), are in excess of the amount thereof that would then be
required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.


 





Section 8.06     Repayment
to Company.


 


Any money deposited with the Trustee or
any Paying Agent, or then held by the Company, in trust for the payment of the principal of, premium, if any, or interest on, any
Note and remaining unclaimed for two years after such principal, premium, if any, or interest has become due and payable shall,
subject to compliance with applicable abandoned property law, be paid to the Company on its request or (if then held by the Company)
will be discharged from such trust; and the Holder of such Note will thereafter be permitted to 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, will thereupon cease.


 


Section 8.07     Reinstatement.


 


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


 


ARTICLE IX


AMENDMENT, SUPPLEMENT
AND WAIVER


 


Section 9.01     Without
Consent of Holders of Notes.


 


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


 


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


 


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


 


(3)            to
provide for the assumption of the Company’s or a Guarantor’s obligations to the Holders of the Notes and Note Guarantees
by a successor to the Company or such Guarantor pursuant to Article V or Article X hereof;


 


(4)            to
make any change that would provide any additional rights or benefits to the Holders of the Notes (including the addition of collateral
to secure the Notes and/or additional guarantees) or that does not adversely affect the legal rights hereunder of any such Holder;


 


(5)            to
conform the text of this Indenture, the Note Guarantees or the Notes to any provision of the “Description of Notes”
section of the Offering Memorandum to the extent that such provision of this Indenture, the Note Guarantees or the Notes was intended
to conform to the text of the “Description of Notes” section of the Offering Memorandum as evidenced by an Officer’s
Certificate;


 






    -82-


     


    

 


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


 


(7)            to
allow any Guarantor to execute a supplemental indenture and/or a Note Guarantee with respect to the Notes or to release any Guarantor
from its Note Guarantee if such release is in accordance with the terms of this Indenture; provided that any such supplemental
indenture may be signed by the Company, the Guarantor providing the Note Guarantee and the Trustee; or


 


(8)            to
evidence and provide for the acceptance and appointment under this Indenture of a successor Trustee pursuant to the requirements
of this Indenture.


 


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 7.02, the Trustee will join with the Company and the 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 will not be obligated to enter into such
amended or supplemental indenture that affects its own rights, duties or immunities under this Indenture or otherwise.


 


Section 9.02     With
Consent of Holders of Notes.


 


Except as provided below in this Section 9.02,
the Company, the Guarantors, and the Trustee may amend or supplement this Indenture (including, without limitation, Sections 3.09,
4.10 and 4.15) or the Notes and the Note Guarantees with the consent of the Holders of at least a majority in aggregate principal
amount of the Notes then outstanding (including, without limitation, Additional Notes, if any) voting as a single class (including,
without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, the Notes), and,
subject to Sections 6.04 and 6.07, 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 and the Note Guarantees may be waived with the
consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes (including, without limitation,
Additional Notes, if any) voting as a single class (including, without limitation, consents obtained in connection with a purchase
of, or tender offer or exchange offer for, the Notes). Section 2.08 shall determine which Notes are considered to be “outstanding”
for purposes of this Section 9.02.


 


Upon the request of the Company accompanied
by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental indenture, and upon the
filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt
by the Trustee of the documents described in Section 7.02(b), the Trustee will join with the Company and the Guarantors in
the execution of such amended or supplemental indenture unless such amended or supplemental indenture directly affects the Trustee’s
own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but will not
be obligated to, enter into such amended or supplemental indenture.


 


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


 


After an amendment, supplement or waiver
under this Section 9.02 or under Section 9.01 becomes effective, the Company will deliver or cause to be delivered to
the Holders of Notes affected thereby a notice briefly describing such amendment, supplement or waiver. Any failure of the Company
to deliver such notice, or any defect therein, will not, however, in any way impair or affect the validity of any such amended
or supplemental indenture or waiver. Subject to Sections 6.04 and 6.07, the Holders of a majority in aggregate principal amount
of the Notes then outstanding voting as a single class may waive compliance in a particular instance by the Company with any provision
of this Indenture or the Notes or the Note Guarantees. However, without the consent of each Holder of Notes affected, an amendment,
supplement or waiver under this Section 9.02 may not (with respect to any Notes held by a non-consenting Holder):


 









    -83-


     


    

 


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


 


(2)            reduce
the principal of or change the fixed maturity of any Note or change the date on which any Note may be subject to redemption or
reduce the redemption price thereof as described in Section 3.07 (except as provided above with respect to Sections 3.09,
4.10 and 4.15);


 


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


 


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


 


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


 


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


 


(7)            amend,
change or modify the obligation of the Company to make and consummate an Asset Sale Offer with respect to any Asset Sale in accordance
with Section 3.09 after the obligation to make such Asset Sale Offer has arisen, or the obligation of the Company to make
and consummate a Change of Control Offer in the event of a Change of Control in accordance with Section 4.15 after such Change
of Control has occurred, including, in each case, amending, changing or modifying any definition relating thereto;


 


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


 


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


 


Section 9.03     Revocation
and Effect of Consents.


 


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


 


Section 9.04     Notation
on or Exchange of Notes.


 


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


 


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




 






    -84-


     


    




 


Section 9.05     Trustee
to Sign Amendments, etc.


 


The Trustee will 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. The Company may not sign an amended or supplemental indenture until the Board of Directors
of the Company has authorized or approved it, or delegated authority to authorize or approve it. In executing any amended or supplemental
indenture, the Trustee will be provided with and (subject to Section 7.01) will be fully protected in relying upon, in addition
to the documents required by Section 12.03, an Officer’s Certificate and an Opinion of Counsel stating that the execution
of such amended or supplemental indenture is authorized or permitted by this Indenture, and that it will be valid and binding upon
the Company and any Guarantor party thereto and enforceable in accordance with its terms.

(a)            Subject

with the terms hereof and thereof; and


 


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


 


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


 


(b)            The
Guarantors hereby agree that their obligations hereunder are unconditional, irrespective of the validity, regularity or enforceability
of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes
with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any action to enforce the same
or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. Subject to
Section 6.06, each Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the
event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice
and all demands whatsoever and covenants that this Note Guarantee will not be discharged except by complete performance of the
obligations contained in the Notes and this Indenture.


 


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

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


 


 Section 10.02     Limitation on Guarantor Liability.




 


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


 


Section 10.03     Execution
and Delivery of Note Guarantee.


 


To evidence its Note Guarantee set forth
in Section 10.01, each Guarantor hereby agrees that a supplemental indenture shall be executed on behalf of such Guarantor
by an Officer of such Guarantor.


 


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


 


If an Officer whose signature is on this
Indenture or on the Note Guarantee no longer holds that office at the time the Trustee authenticates the Note on which a Note Guarantee
is endorsed, the Note Guarantee will be valid nevertheless.


 


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


 


In the event that the Company or any of
its Restricted Subsidiaries creates or acquires any Domestic Subsidiary after the date of this Indenture, if required by Section 4.18,
the Company will cause such Domestic Subsidiary to comply with the provisions of Section 4.18 and this Article X, to
the extent applicable.


 


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


 


Except as otherwise provided in Section 10.05,
no Guarantor may sell or otherwise dispose of all or substantially all of its assets to, or consolidate with or merge with or into,
or consummate a Division as the Dividing Person with (whether or not such Guarantor is the surviving Person or Division Successor,
as applicable) another Person, other than the Company or another Guarantor, unless:


 


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


 


(2)            either:


 


(a)            such
Guarantor is the surviving Person in such merger or consolidation or the Person acquiring the property in any such sale or disposition
or the Person formed by or surviving any such consolidation or merger or the Division Successor in the case of a Division assumes
all the obligations of that Guarantor under this Indenture and its Note Guarantee on the terms set forth herein or therein, pursuant
to a supplemental indenture; or


 






    -86-


     


    

 


(b)            such
sale or other disposition or Division is permitted under this Indenture and the Net Proceeds of such sale or other disposition
are applied in accordance with the applicable provisions of this Indenture, including without limitation, Section 4.10.


 


The foregoing requirements of this paragraph shall not apply
to (1) a reincorporation of a Guarantor if, in the good faith determination of the Board of Directors of the Guarantor, whose
determination shall be evidenced by a board resolution delivered to the Trustee, the principal purpose of such transaction is to
change the state of incorporation of such Guarantor and any such transaction shall not have as one of its purposes the evasion
of the foregoing limitations, (2) a consolidation or merger with or into or winding up into or transfer of all or part of
a Guarantor’s properties and assets to the Company or any Guarantor, (3) conversion into a corporation, partnership,
limited partnership, limited liability company or trust organized or existing under the laws of the jurisdiction of organization
of such Guarantor, or (4) a liquidation or dissolution of such Guarantor if the Company determines in good faith that such
action is in the best interests of the Company and is not materially disadvantageous to the Holders, in each case, without regard
to the requirements set forth in the preceding paragraph.


 


In case of any such consolidation, merger,
sale or conveyance and upon the assumption by the successor Person, by supplemental indenture executed and delivered to the Trustee,
of the Note Guarantee and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed
by the Guarantor, such successor Person shall succeed to and be substituted for the Guarantor with the same effect as if it had
been named herein as a Guarantor. All the Note Guarantees so issued shall in all respects have the same legal rank and benefit
under this Indenture as the Note Guarantees theretofore and thereafter issued in accordance with the terms of this Indenture as
though all of such Note Guarantees had been issued at the date of the execution hereof.


 


Except as set forth in Articles IV and V
hereof, and notwithstanding clauses 2(a) and (b) above, nothing contained in this Indenture or in any of the Notes will
prevent any consolidation or merger of a Guarantor with or into the Company or another Guarantor, or will prevent any sale or conveyance
of the property of a Guarantor as an entirety or substantially as an entirety to the Company or another Guarantor.


 


Section 10.05     Releases


 


The Note Guarantee of a Guarantor shall
be automatically released upon:


 


(a)            any
sale or other disposition of all or substantially all of the assets of such Guarantor (including by way of merger or consolidation)
to a Person that is not (either before or after giving effect to such transactions) the Company or a Restricted Subsidiary of the
Company; provided that such sale or other disposition is permitted by Section 3.09, Section 4.10 or Section 5.01;


 


(b)            any
sale or other disposition of the Capital Stock of such Guarantor, after which the applicable Guarantor is no longer a Restricted
Subsidiary, to a Person that is not (either before or after giving effect to such transaction) a Restricted Subsidiary of the Company;
provided that such sale or other disposition is permitted by Section 3.09, Section 4.10 or Section 5.01;


 


(c)            in
connection with the release or discharge of such Guarantor from all guarantee obligations of such Guarantor with respect to the
Credit Agreement or any other Credit Facility that gave rise to the obligation to provide such Note Guarantee, except a release
or discharge by or as a result of payment under such Guarantee or direct obligation;


 


(d)            the
designation of such Restricted Subsidiary that is a Guarantor as an Unrestricted Subsidiary in accordance with the terms of this
Indenture (including Section 4.19); or


 






    -87-


     


    





 


(e)            Legal
Defeasance in accordance with Article VIII or satisfaction and discharge of this Indenture in accordance with Article XI;
and


 


Upon request of the Company and upon delivering
to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for
in this Indenture relating to such transaction have been complied with, the Trustee shall execute an instrument acknowledging the
release of such Guarantor (in form and substance reasonably satisfactory to the Trustee).


 


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


 


ARTICLE XI

SATISFACTION AND DISCHARGE


 


Section 11.01         Satisfaction
and Discharge


 


This Indenture will be discharged and will
cease to be of further effect as to all Notes issued hereunder, when:


 


(1)            either:


 


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


 


(b)            all
Notes that have not been delivered to the Trustee for cancellation have become due and payable by reason of the delivery of a notice
of redemption or otherwise or will become due and payable within one year and the Company or any Guarantor has irrevocably deposited
or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders, cash in U.S. dollars,
in amounts as will be sufficient, without consideration of any reinvestment of interest, to pay and discharge the entire Indebtedness
on the Notes not delivered to the Trustee for cancellation for principal, premium, if any, and accrued interest to the date of
maturity or redemption;


 


(2)            no
Default or Event of Default has occurred and is continuing on the date of such deposit or will occur as a result of the deposit
(other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit and the granting
of Liens in connection therewith) and the deposit will not result in a breach or violation of, or constitute a default under, any
other instrument (other than this Indenture) to which the Company or any Guarantor is a party or by which the Company or any Guarantor
is bound;


 


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


 


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


 


In addition, the Company must deliver an
Officer’s Certificate and an Opinion of Counsel to the Trustee stating that all conditions precedent to satisfaction and
discharge have been satisfied. Upon Company request and delivery to the Trustee of an Officer’s Certificate and an Opinion
of Counsel as described above, the Trustee shall acknowledge in writing the discharge of the obligations of the Company and the
Guarantors under this Indenture (except for those surviving rights, powers, trusts, duties and immunities of the Trustee hereunder
and the Company’s and Guarantors’ obligations in connection therewith).


 






    -88-


     


    

 


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


 


Section 11.02         Application
of Trust Money.


 


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


 


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

3.875% Senior Unsecured Notes due 2028


 


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


 


(1)            Interest.
Emergent BioSolutions Inc, a Delaware corporation (the “Company”), promises to pay interest on the principal
amount of this Note at 3.875% per annum from August 7, 20206,
until maturity. The Company will pay interest, if any, semiannually in arrears on February 15 and August 15 of each year
(each, an “Interest Payment Date”). Interest on the Notes will accrue from the most recent date to which
interest has been paid or, if no interest has been paid, from the date of issuance; provided that if there is no existing
Default in the payment of interest, and if this Note is authenticated between a record date referred to on the face hereof and
the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date; provided,
further, that the first Interest Payment Date shall be February 15, 20217.
The Company will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal
at the rate equal to 1% per annum in excess of the then applicable interest rate on the Notes to the extent lawful; it will pay
interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (without
regard to any applicable grace period) at the same rate to the extent lawful. Interest will be computed on the basis of a 360-day
year of twelve 30-day months.


 


(2)            Method
of Payment. The Company will pay interest on the Notes (except defaulted interest), if any, to the Persons who are registered
Holders of Notes at the close of business on the February 1 or August 1 next preceding the Interest Payment Date, even
if such Notes are canceled after such record date and on or before such Interest Payment Date, except as provided in Section 2.12
of the Indenture with respect to defaulted interest. The Notes will be payable as to principal, premium, if any, and interest at
the office or agency of the Company maintained for such purpose, or, at the option of the Company, payment of interest, if any,
may be made by check mailed to the Holders at their addresses set forth in the register of Holders; provided that payment
by wire transfer of immediately available funds will be required with respect to principal of and interest, premium, if any, on,
all Global Notes and all other Notes the Holders of which will have provided wire transfer instructions to the Company or the Paying
Agent. Such payment will be in such coin or currency of the United States of America as at the time of payment is legal tender
for payment of public and private debts. If any payment date is not a Business Day, payment will be made on the next succeeding
Business Day with the same force and effect and no interest shall accrue for the intervening period.


 


(3)            Paying
Agent and Registrar. Initially, U.S. Bank National Association, the Trustee under the Indenture, will act as Paying Agent and
Registrar. The Company may change any Paying Agent or Registrar without notice to any Holder. The Company or any of its Subsidiaries
may act in any such capacity.


 


(4)            Indenture.
The Company issued the Notes under an Indenture dated as of August 7, 2020 (the “Indenture”) among
the Company, the Guarantors from time to time party thereto and the Trustee. The Notes are subject to all the terms and provisions
of the Indenture, and Holders are referred to the Indenture for a statement of such terms and provisions. To the extent any provision
of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling.
The Notes are unsecured obligations of the Company. The Indenture does not limit the aggregate principal amount of Notes that may
be issued thereunder.


 


(5)            Optional
Redemption.


 


(a)            Except
as set forth in subparagraphs (b) and (d) of this Paragraph 5, the Notes will not be redeemable at the Company’s
option prior to August 15, 2023. On or after August 15, 2023, the Company may redeem all or a part of the Notes upon
not less than 15 nor more than 60 days’ notice, at the redemption prices (expressed as percentages of principal amount) set
forth below plus accrued and unpaid interest, if any, on the Notes redeemed, to the applicable redemption date, if redeemed during
the twelve-month period beginning on August 15 of the years indicated below, subject to the rights of Holders of Notes on
the relevant record date to receive interest on the relevant interest payment date:

		7	With respect to Notes issued on the Issue Date.



 


 






    A-4


     


    

 


	Year	 	Percentage	 
	2023	 	 	101.938%	
	2024	 	 	100.969%	
	2025 and thereafter	 	 	100.000%	



 


Unless the Company defaults in the payment
of the redemption price, interest will cease to accrue on the Notes or portions thereof called for redemption on and after the
applicable redemption date.


 


(b)            Notwithstanding
the provisions of subparagraph (a) of this Paragraph 5, at any time prior to August 15, 2023, the Company may on any
one or more occasions redeem up to 40% of the aggregate principal amount of Notes issued under the Indenture at a redemption price
of 103.875% of the principal amount, plus accrued and unpaid interest, if any, to the redemption date with the net cash proceeds
of one or more Equity Offerings of the Company; provided that (1) at least 60% of the aggregate principal amount of
Notes originally issued under the Indenture (excluding Notes held by the Company and its Subsidiaries) remains outstanding immediately
after the occurrence of such redemption, and (2) the redemption occurs within 180 days of the date of the closing of such
Equity Offering.


 


(c)            Notices
of any redemption of the notes may be subject to the satisfaction of one or more conditions precedent established by the Company,
in its sole discretion. If applicable, such notice shall state that, at the discretion of the Company, the redemption date may
be delayed until such time as any or all such conditions have been satisfied (or waived). In addition, any redemption or notice
of any redemption with the proceeds of an Equity Offering pursuant to the prior paragraph may, at the Company’s discretion,
be subject to one or more conditions precedent, including, but not limited to, completion of such Equity Offering and may be given
prior to the completion thereof.


 


(d)            At
any time prior to August 15, 2023, the Company may redeem all or a part of the notes upon notice as described in Section 3.03
of the Indenture at a redemption price equal to 100% of the principal amount of the notes redeemed plus the Applicable Premium
as of, and accrued and unpaid interest, if any, to, but excluding the redemption date, subject to the rights of Holders of record
on the relevant record date to receive interest due on the relevant interest payment date. Calculation of the Applicable Premium
will be made by the Company or on its behalf by such Person as the Company may designate; provided that such calculation
or the correctness thereof shall not be a duty or obligation of the Trustee.


 


(6)            Open
Market Purchases. For the avoidance of doubt, the Company may at any time and from time to time purchase the Notes in the open
market or otherwise.


 


(7)            Repurchase
at the Option of Holder.


 


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


 






    A-5


     


    

 


If the Company or a Restricted Subsidiary
of the Company consummates any Asset Sales, within thirty days of each date on which the aggregate amount of Excess Proceeds exceeds
$100.0 million, unless waived or modified with the consent of the Holders of at least a majority in aggregate principal amount
of the Notes then outstanding, the Company will commence an offer to all Holders of Notes (with a copy to the Trustee) and all
holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in the
Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets (an “Asset Sale Offer”)
in accordance with Section 3.09 of the Indenture to purchase the maximum principal amount of Notes and such other pari
passu Indebtedness that may be purchased out of the Excess Proceeds. The offer price in any Asset Sale Offer will be equal
to 100% of the principal amount plus accrued and unpaid interest, if any, to the date of purchase, and will be payable in cash,
in accordance with the procedures set forth in the Indenture. If any Excess Proceeds remain after the consummation of an Asset
Sale Offer, the Company may use those Excess Proceeds for any purpose not otherwise prohibited by the Indenture. If the aggregate
principal amount of Notes and other pari passu Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess
Proceeds, the Company will select the Notes and such other pari passu Indebtedness to be purchased on a pro rata basis.
Holders of Notes that are the subject of an offer to purchase will receive an Asset Sale Offer from the Company prior to any related
purchase date and may elect to have such Notes purchased by completing the form entitled “Option of Holder to Elect Purchase”
attached to the Notes.


 


(8)            Notice
of Redemption. Notice of redemption will be sent at least 15 days but not more than 60 days before the redemption date to each
Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be sent more than 60 days prior
to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of the
Indenture. Notes in denominations larger than $2,000 may be redeemed in part but only in whole multiples of $1,000 thereof, unless
all of the Notes held by a Holder are to be redeemed.


 


(9)            Denominations,
Transfer, Exchange. The Notes are in registered form without coupons in denominations of $2,000 and integral multiples of $1,000
in excess thereof. The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Registrar
and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Company
may require a Holder to pay any taxes and fees required by law or permitted by the Indenture. The Company need not exchange or
register the transfer of any Note or portion of a Note selected for redemption, except for the unredeemed portion of any Note being
redeemed in part. Also, the Company need not exchange or register the transfer of any Notes for a period of 15 days before a selection
of Notes to be redeemed or during the period between a record date and the corresponding Interest Payment Date.


 


(10)          Persons
Deemed Owners. The registered Holder of a Note may be treated as its owner for all purposes.


 


(11)          Amendment,
Supplement and Waiver. Subject to certain exceptions, the Indenture, the Notes or the Note Guarantees may be amended or supplemented
with the consent of the Holders of at least a majority in aggregate principal amount of the then outstanding Notes (including,
without limitation, Additional Notes, if any) voting as a single class (including, without limitation, consents obtained in connection
with a tender offer or exchange offer for, or purchase of, the Notes), and 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 the Indenture or the Notes
or the Note Guarantees may be waived with the consent of the Holders of a majority in aggregate principal amount of the then outstanding
Notes (including, without limitation, Additional Notes, if any) voting as a single class (including, without limitation, consents
obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes). Without the consent of any Holder
of a Note, the Indenture or the Notes or the Note Guarantees may be amended or supplemented to cure any ambiguity, defect or inconsistency;
to provide for uncertificated Notes in addition to or in place of certificated Notes; to provide for the assumption of the Company’s
or a Guarantor’s obligations to Holders of the Notes and Note Guarantees by a successor to the Company or such Guarantor
pursuant to Article V or Article X of the Indenture; to 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; to conform
the text of the Indenture, the Note Guarantees or the Notes to any provision of the “Description of Notes” section
of the Company’s Offering Memorandum dated August 4, 2020, relating to the initial offering of the Notes, to the extent
that such provision of the Indenture, the Note Guarantees or the Notes was intended to conform to the text of the “Description
of Notes” as evidenced by an Officer’s Certificate; to provide for the issuance of Additional Notes in accordance with
the limitations set forth in the Indenture; to allow any Guarantor to execute a supplemental indenture to the Indenture and/or
a Note Guarantee with respect to the Notes or to release any Guarantor from its Note Guarantee if such release is in accordance
with the terms of the Indenture, provided any such supplemental indenture may be signed by the Company, the Guarantor providing
the Note Guarantee and the Trustee; or to evidence and provide for the acceptance and appointment under the Indenture of a successor
Trustee pursuant to the requirements of the Indenture.

(12)          Defaults
and Remedies. Events of Default include: (i) default for 30 days in the payment when due of interest on the Notes; (ii) default
in the payment when due (at maturity, upon redemption or otherwise) of the principal of, or premium, if any, on, the Notes; (iii) failure
by the Company or any of its Restricted Subsidiaries to comply with the provisions of Section 5.01 of the Indenture; (iv) failure
by the Company or any of its Restricted Subsidiaries to comply with the provisions of Section 4.15 of the Indenture; (v) failure
by the Company or any of its Restricted Subsidiaries for 60 days after written notice to the Company by the Trustee or to the Company
and the Trustee by the Holders of at least 25% in aggregate principal amount of the Notes then outstanding voting as a single class
to comply with any of the other agreements in the Indenture; provided that in the case of a failure to comply with Section 4.03
of the Indenture, such period of continuance of such default or breach shall be 90 days after a written notice described in this
clause (v) has been given; (vi) default under any mortgage, indenture or instrument under which there be issued or by
which there may be secured or evidenced any Indebtedness for money borrowed by the Company or any of its Restricted Subsidiaries
(or the payment of which is guaranteed by the Company or any of its Restricted Subsidiaries), other than Indebtedness owed to the
Company or a Restricted Subsidiary, whether such Indebtedness or Guarantee now exists, or is created after the date of the Indenture,
if that default: (a) is caused by a failure to pay principal of, or interest or premium, if any, on, such Indebtedness at
final maturity thereof, prior to the expiration of the grace period provided in such Indebtedness on the date of such default (a
“Payment Default”); or (b) results in the acceleration of such Indebtedness prior to its express
maturity; and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such
Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates $50.0 million
(or its foreign currency equivalent) or more; (vii) failure by the Company or any of its Restricted Subsidiaries to pay final
judgments entered by a court or courts of competent jurisdiction aggregating in excess of $50.0 million (or its foreign currency
equivalent) net of any amounts covered by independent third party insurance and as to which such insurer has not disputed coverage,
which judgments are not paid, discharged or stayed for a period of 60 consecutive days; (viii) except as permitted by the
Indenture, any Note Guarantee of a Significant Subsidiary is held in any judicial proceeding to be unenforceable or invalid or
ceases for any reason to be in full force and effect or any Guarantor, or any Person acting on behalf of any Guarantor, denies
or disaffirms its obligations under its Note Guarantee; and (ix) certain events of bankruptcy or insolvency described in the
Indenture with respect to the Company or any of its Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted
Subsidiaries that, taken together, would constitute a Significant Subsidiary. If any Event of Default occurs and is continuing,
the Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes may declare all the Notes
to be due and payable immediately; provided, that a notice of a Default or Event of Default may not be given with respect
to any action taken, and reported publicly or to Holders, more than two years prior to such notice of Default or Event of Default.
Notwithstanding the foregoing, in the case of an Event of Default arising from certain events of bankruptcy or insolvency, all
outstanding Notes will become due and payable immediately without further action or notice. Holders may not enforce the Indenture
or the Notes except as provided in the Indenture. Subject to certain limitations, Holders of a majority in aggregate principal
amount of the then outstanding Notes may direct the time, method and place of conducting any proceeding for exercising any remedy
available to the Trustee or exercising any trust or power conferred on it. Except in the case of a Default or Event of Default
in payment of principal of, premium, if any, or interest on, any Note, the Trustee may withhold the notice of Default or Event
of Default if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in
the interests of the Holders of the Notes. If certain conditions are satisfied, the Holders of at least a majority in aggregate
principal amount of the then outstanding Notes by notice to the Trustee may, on behalf of the Holders of all of the Notes, rescind
an acceleration provided all amounts owing to the Trustee have been paid or waive any existing Default or Event of Default and
its consequences under the Indenture except a continuing Default or Event of Default in the payment of interest or premium, if
any, on, or the principal of, the Notes. The Indenture requires the Company to deliver to the Trustee annually within 90 days after
the end of each fiscal year a statement regarding compliance with the Indenture.

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


 


(14)          No
Recourse Against Others. A director, officer, employee, incorporator or stockholder of the Company or any of the Guarantors,
as such, will not have any liability for any obligations of the Company or the Guarantors 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 waives and releases all such liability. The waiver and release are part of the consideration for the issuance
of the Notes.

as a convenience to Holders. The Company has also caused ISINs to be printed on the Notes, and the Trustee may also use ISINs in
notices of redemption as a convenience to Holders. No representation is made as to the accuracy of such numbers either as printed
on the Notes or as contained in any notice of redemption, and reliance may be placed only on the other identification numbers placed
thereon.

THEREUNDER ARE AND SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK WITHOUT GIVING EFFECT

WHEREAS, the Company has heretofore executed
and delivered to the Trustee an indenture (the “Indenture”), dated as of August 7, 2020 providing for the
issuance of 3.875% Senior Unsecured Notes due 2028 (the “Notes”);


 


WHEREAS, the Indenture provides that under
certain circumstances the Guaranteeing Subsidiary shall execute and deliver to the Trustee a supplemental indenture pursuant to
which the Guaranteeing Subsidiary shall unconditionally guarantee all of the Company’s Obligations under the Notes and the
Indenture on the terms and conditions set forth herein (the “Note Guarantee”); and


 


WHEREAS, pursuant to Section 9.01 of
the Indenture, the Trustee is authorized to execute and deliver this Supplemental Indenture.


 


NOW, THEREFORE, in consideration of the
foregoing and for other good and valuable consideration, the receipt of which is hereby acknowledged, the Company, the Guaranteeing
Subsidiary and the Trustee mutually covenant and agree for the equal and ratable benefit of the Holders of the Notes as follows:


 


1.            Capitalized
Terms. Capitalized terms used herein without definition shall have the meanings assigned to them in the Indenture.


 


2.            Agreement
to Guarantee. The Guaranteeing Subsidiary hereby becomes a party to the Indenture as a Guarantor and as such shall have all
of the rights and be subject to all of the obligations and agreements of a Guarantor under the Indenture. The Guaranteeing Subsidiary
hereby agrees, on a joint and several basis with all the existing Guarantors, to provide an unconditional Guarantee on the terms
and subject to the conditions set forth in the Note Guarantee and in the Indenture including but not limited to Article X
thereof.


 


3.            Ratification
of Indenture; Supplemental Indentures Part of Indenture. Except as expressly amended hereby, the Indenture is in all respects
ratified and confirmed and all the terms, conditions and provisions thereof shall remain in full force and effect. This Supplemental

the Notes, any Note Guarantees, the Indenture or this Supplemental Indenture or for any claim based on, in respect of, or by reason
of, such obligations or their creation. Each Holder of the Notes by accepting a Note waives and releases all such liability. The
waiver and release are part of the consideration for issuance of the Notes. Such waiver may not be effective to waive liabilities
under the federal securities laws and it is the view of the SEC that such a waiver is against public policy.


 


5.            GOVERNING
LAW. THIS SUPPLEMENTAL INDENTURE SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK
WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION

together represent the same agreement.
