Section
2.07           Replacement
Notes.

 

If any mutilated Note
is surrendered to the Trustee or the Company and 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, security or an indemnity satisfactory
to the Trustee or the Company, as applicable, must be supplied by the Holder 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 Holder must also provide the Trustee
any other documents (including a lost note affidavit) that the Trustee may request. The Company and/or the Trustee may charge for
its expenses in replacing a Note.

 

If, after delivery
of such new Note, a protected purchaser of the predecessor Note presents for payment, transfer or exchange such replaced Note,
the Company, the Trustee, any Agent and any authenticating agent shall be entitled to recover such new Note from the Person to
whom it was delivered or any Person taking therefrom, and shall be entitled to recover upon the security or indemnity provided
therefor to the extent of any loss, damage, cost or expense incurred by the Company, the Trustee, any Agent and any authenticating
agent in connection therewith.

 

Every replacement Note
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 hereof, 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) hereof.

 

    47

     

    

 

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

 

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

 

If the Paying Agent
(other than the 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 receives an Officers’ Certificate from the Company that such Notes are so owned will be so disregarded. Upon request
of the Trustee, the Company shall furnish to the Trustee promptly an Officers’ Certificate listing and identifying all Notes,
if any, known by the Company to be owned or held by or for the account of any of the above described Persons, and the Trustee shall
be entitled to accept and rely upon such Officers’ Certificate as conclusive evidence of the facts therein set forth and
of the fact that all Notes not listed therein are outstanding for the purpose of any determination.

 

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, upon receipt of an Authentication Order, 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 destroy canceled Notes in its customary manner. Certification
of the destruction 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.

 

    48

     

    

 

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 hereof. 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 mail or cause to be mailed 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           Series A
Preferred Stock.

 

(a)           The
Company will issue one (1) share of Series A Preferred Stock (the “Series A Preferred Stock”)
to be held in Trust by the Trustee on behalf of Holders to (i) provide certain rights and protections to the holders of the
Notes and (ii) allow, under certain circumstances detailed below, the Holders to vote on an “as-converted” basis.
The Trustee shall take direction from Holders of fifty and one-tenth percent (50.1%) of the Notes for any action requiring the
consent of the holders of the Series A Preferred Stock or each act on which the Holder of the Series A Preferred Stock
is entitled to vote.

 

(b)           Following
a Default or Event of Default under this Indenture, the Series A Preferred Stock shall be entitled to vote with the Common
Stock of the Company as a single class and having voting power equal to the number of shares of Common Stock of the Company issuable
upon the conversion of the Notes.

 

(c)           At
all times when the Common Stock is entitled to vote thereon, the Series A Preferred Stock shall be entitled to vote with the
Common Stock of the Company as a single class and having voting power equal to the number of shares of Common Stock of the Company
issuable upon the conversion of the Notes for any transaction: (a) modifying, amending, supplementing, or waiving any provision
of the Company’s organizational documents or (b) entering into any merger, consolidation, sale of all or substantially
all of the assets of the Company, or other business combination transaction.

 

(d)           The
holder of the Series A Preferred Stock shall have the right to appoint two (2) directors to the Board, both of whom shall
be independent.

 

(e)           One
(1) share of Series A Preferred Stock shall (i) rank pari passu in respect of voting rights with respect
to the Common Stock of the Company, (ii) have a liquidation preference equal to $1.00, (iii) not produce preferred dividends
or ordinary dividends, (iv) not be transferable, except to a successor Trustee under the terms of this Indenture, and (vi) not
be granted registration rights. The Series A Preferred Stock shall be governed in all respects by the laws of the State of
Delaware.

 

    49

     

    

 

(f)            The
Series A Preferred Stock may be redeemed by the Company upon the exercise into Common Stock of, in the aggregate, seventy-five
percent (75%) or more of the Notes that were issued on the Issue Date. The redemption price shall be $1.00.

 

(g)           The
Trustee is not obligated to solicit the consent or request the approval of the Holders to requests or actions pursuant to Series A
Preferred Stock. A consent solicitation agent appointed by the Company will solicit such vote and will provide to the Holders notice
of such requests or actions and a ballot to vote to consent or approve or deny the action with instructions to return such ballot
to it. The Trustee shall then act in accordance with the direction of a majority of Holders of the outstanding Series A Preferred
Stock, as calculated by the consent solicitation agent. The Trustee shall have no liability for any failure to act resulting from
the late return of, or failure to return, any proxy sent by the Company or consent solicitation agent to the Holders.

by law or applicable stock exchange or depositary requirements.

 

The Company will promptly
notify the Trustee in writing of the 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

Section 3.03           Notice
of Redemption.

 

Subject to the provisions
of Section 3.09 hereof, at least 30 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 given 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 8 or 12 hereof. Notice of any redemption, including,
without limitation, upon an Equity Offering, may, at the Company’s discretion, be subject to one or more conditions precedent,
including, but not limited to, completion of the related Equity Offering.

 

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

 

(i)             the
redemption date;

 

(ii)            the
redemption price;

 

(iii)           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

(vii)         the

and

 

(viii)        that

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 mailed in accordance with Section 3.03 hereof, Notes called for redemption become due and payable on the redemption date
at the redemption price, unless the redemption is subject to a condition precedent that is not satisfied or waived.

 

    51

     

    

 

Section 3.05           Deposit
of Redemption or Purchase Price.

 

At least 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 of, and accrued interest on all Notes to be redeemed or purchased on that date and to pay
any amounts owing to the Trustee and the Collateral Agent. 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, accrued interest on all Notes to be redeemed or purchased and to pay any amounts owing to the Trustee and
the Collateral Agent.

 

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 accepted for 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 tendered for 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 hereof.

any time prior to December 15, 2023, the Company may on any one or more occasions redeem all or a part of the Notes, upon
not less than 30 nor more than 60 days’ notice, at a redemption price equal to 100.0% of the principal amount of the Notes
redeemed, plus the Applicable Premium as of, and accrued and unpaid interest to the applicable date of redemption, subject to the

plus accrued and unpaid interest to the applicable date of redemption subject to the rights of holders of Notes on the relevant
record date to receive interest on the relevant interest payment date.

 

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 the applicable redemption date.

 

    52

Redemption.

 

Except as set forth
below under Sections 4.10 and 4.14 hereof, the Company is not required to make mandatory redemption or sinking fund payments with
respect to the Notes or to repurchase the Notes at the option of Holders of the Notes.

 

Section 3.09           Offer
to Purchase by Application of Excess Proceeds.

 

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

 

The Asset Sale Offer
shall be made to all Holders and all holders of Second Lien Debt containing provisions similar to those set forth in this Indenture
with respect to offers to purchase, prepay or redeem with the proceeds of sales of assets. The Asset Sale Offer shall 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 Second Lien Debt (on a pro rata basis based on the principal
amount of Notes and such other Second Lien Debt surrendered, if applicable) or, if less than the Offer Amount has been tendered,
all Notes and other Second Lien Debt tendered in response to the Asset Sale Offer. Payment for any Notes so purchased will be made
in the same manner as interest payments are made.

 

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

 

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

 

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

 

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

 

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

 

    53

     

    

 

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

 

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

 

(vi)          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;

 

(vii)         that
Holders will be entitled to withdraw their election if the Company, the Depositary or the Paying Agent, as the case may be, receives,
not later than the expiration of the Offer Period, a telegram, telex, 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 or her election to have such Note purchased;

 

(viii)        that,
if the aggregate principal amount of Notes and other Second Lien Debt surrendered by holders thereof exceeds the Offer Amount,
the Company will select the Notes and other Second Lien Debt to be purchased on a pro rata basis based on the principal
amount of Notes and such other Second Lien Debt surrendered (with such adjustments as may be deemed appropriate by the Company
so that only Notes in denominations of $1,000, or an integral multiple of $1,000 in excess thereof, will be purchased); and

 

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

 

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

 

    54

     

    

 

Other than as specifically
provided in this Section 3.09, any purchase pursuant to this Section 3.09 shall be made pursuant to the provisions of
Sections 3.01 through 3.06 hereof.

Section 4.01           Payment
of Notes.

 

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

 

The Company will pay
interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal at a rate that is 1%
higher than the then applicable interest rate on the Notes to the extent lawful; 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.

 

Section 4.02           Maintenance
of Office or Agency.

 

The Company will maintain
an office or agency (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.

 

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. 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
hereof.

 

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 Holders of Notes (or file with the SEC for public availability), within the time periods specified in the SEC’s rules and
regulations:

 

    55

     

    

 

(i)            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, including a “Management’s Discussion and Analysis of Financial Condition and Results of Operations”
and, with respect to the annual information only, a report thereon by the Company’s certified independent accountants; and

 

(ii)           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. In addition,
the Company will file a copy of each of the reports referred to in clauses (i) and (ii) 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 within those time periods. The Company will at all times comply
with TIA §314(a).

 

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 the preceding paragraphs 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 the preceding paragraphs on its website within the time periods that would apply if the Company
were required to file those reports with the SEC.

 

(b)           If
the Company has designated any of its Subsidiaries as Unrestricted Subsidiaries, then the quarterly and annual financial information
required by paragraph (a) of this Section 4.03 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 and to securities analysts
and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under
the Securities Act.]

 

(d)           Delivery
of such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of
such 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 hereunder (as to which the Trustee is entitled to rely exclusively
on Officers’ Certificates).

 

    56

     

    

 

Section 4.04          Compliance
Certificate.

 

(a)           The
Company and each Guarantor (to the extent that such Guarantor is so required under the TIA) shall deliver to the Trustee, within
90 days after the end of each fiscal year (beginning with the fiscal year ending on December 31, 2021), an Officers’
Certificate 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 Officers with a view to determining whether the Company has kept, observed, performed
and fulfilled its obligations under this Indenture and the Security Documents, and further stating, as to each such Officer signing
such certificate, that to the best of his or her knowledge the Company has kept, observed, performed and fulfilled each and every
covenant contained in this Indenture and the Security Documents and is not in default in the performance or observance of any of
the terms, provisions and conditions of this Indenture or the Security Documents (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 the best of his or her knowledge no event has occurred and remains in existence
by reason of which payments on account of the principal of, premium on, if any, or interest 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 the Trustee, forthwith upon any Officer becoming aware of
any Default or Event of Default, an Officers’ Certificate specifying such Default or Event of Default and what action the
Company is taking or proposes to take with respect thereto.

 

Section 4.05           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.

pursuant to the Fixed Charge Coverage Ratio test set forth in Section 4.09(a) hereof; and

 

(C)          such

if effected within 120 days before or after such contribution, sale or incurrence, as the case may be.

 

(e)           For
purposes of determining compliance with this Section 4.07, in the event that a Restricted Payment meets the criteria of more

or as a Permitted Investment or is entitled to be made pursuant to Section 4.07(a), the Company will be permitted to divide
or classify (or later divide, classify or reclassify in whole or in part in its sole discretion) such Restricted Payment in any
manner that complies with this Section 4.07.

(a)            The
Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create or permit to exist

dividends or make any other distributions on its Capital Stock to the Company or any of its Restricted Subsidiaries, or with respect
to any other interest or participation in, or measured by, its profits, or pay any indebtedness owed to the Company or any of its
Restricted Subsidiaries; provided that the priority that any series of preferred stock of a Restricted Subsidiary has in
receiving dividends, distributions or liquidating distributions before dividends, distributions or liquidating distributions are
paid in respect of Common Stock of such Restricted Subsidiary shall not constitute a restriction on the ability to make dividends
or distributions on Capital Stock for purposes of this Section 4.08;

 

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

 

(iii)          sell,
lease or transfer any of its properties or assets to the Company or any of its Restricted Subsidiaries.

 

(b)            The

governing Existing Indebtedness and Credit Facilities as in effect on the date of this Indenture and any amendments, restatements,
modifications, renewals, supplements, refundings, replacements or refinancings of those agreements; provided that the amendments,
restatements, modifications, renewals, supplements, refundings, replacements or refinancings are not materially more restrictive,
taken as a whole, with respect to such dividend and other payment restrictions than those contained in those agreements on the
date of this Indenture;

 

(ii)            this
Indenture, the Notes, the Note Guarantees, and the Security Documents;

 

(iii)          agreements
governing other Indebtedness permitted to be incurred by the Company or any Guarantor under Section 4.09 hereof and any amendments,
restatements, modifications, renewals, supplements, refundings, replacements or refinancings of those agreements; provided that
the encumbrances or restrictions contained therein are not, in the reasonable good faith judgment of the Chief Executive Officer
and the Chief Financial Officer of the Company, materially more restrictive, taken as a whole, than those contained in this Indenture,
the Notes and the Note Guarantees;

 

    63

     

    

 

(iv)          applicable
law, rule, regulation or order;

instrument governing Indebtedness or Capital Stock of a Person acquired by the Company or any of its Restricted Subsidiaries as
in effect at the time of such acquisition (except to the extent such Indebtedness or Capital Stock was incurred in connection with
or in contemplation of such acquisition), which encumbrance or restriction is not applicable to any Person, or the properties or
assets of any Person, other than the Person, or the property or assets or Subsidiaries of the Person, so acquired (plus improvements
and accessions to, such property or proceeds or distributions thereof) and any amendments, restatements, modifications, renewals,
extensions, supplements, increases, refundings, replacements or refinancings thereof; provided that the encumbrances and
restrictions in any such amendments, restatements, modifications, renewals, extensions, supplements, increases, refundings, replacements
or refinancings are, in the reasonable good faith judgment of the Chief Executive Officer and Chief Financial Officer of the Company,
no more restrictive, taken as a whole, than those in effect on the date of the acquisition; provided, further, that
in the case of Indebtedness, such Indebtedness was permitted by the terms of this Indenture to be incurred;

 

(vi)          customary
non-assignment provisions in contracts and licenses entered into in the ordinary course of business;

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

 

(ix)           Permitted
Refinancing Indebtedness; provided that the restrictions contained in the agreements governing such Permitted Refinancing
Indebtedness are not materially more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness
being refinanced;

 

(x)            Liens
permitted to be incurred under the provisions of Section 4.12 hereof that limit the right of the debtor to dispose of the
assets subject to such Liens;

 

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

 

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

 

    64

     

    

 

(xiii)        any
agreement or instrument relating to any property or assets acquired after the date of this Indenture, so long as such encumbrance
or restriction relates only to the property or assets so acquired (plus improvements and accessions to, such property or proceeds
or distributions thereof) and is not and was not created in anticipation of such acquisition; and

 

(xiv)        existing
under, by reason of or with respect to provisions with respect to any Indebtedness incurred by a Restricted Subsidiary in compliance
with Section 4.09 hereof, or any agreement pursuant to which such Indebtedness is issued, if the encumbrance or restriction
is not materially more disadvantageous to the Holders of the Notes than is customary in comparable financings (as determined by
the Board of Directors of the Company) and the Board of Directors of the Company determines that any such encumbrance or restriction
will not materially affect the Company’s ability to pay interest or principal on the Notes.

 

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 the Guarantors 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.

 

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

 

(i)            the
incurrence by the Company and any Guarantor of additional Indebtedness and letters of credit under one or more Credit Facilities
in an aggregate principal amount at any one time outstanding under this clause (i) (with letters of credit being deemed to
have a principal amount equal to the maximum potential liability of the Company and any Guarantor thereunder) not to exceed $75.0
million less (x) the amount of Indebtedness incurred by Foreign Subsidiaries outstanding under clause (xxi) below, and
(y) the amount of Indebtedness outstanding under clause (xix) below except to the extent subject to a Lien permitted
by item (25) of the definition of “Permitted Liens,” and (z) the amount of Indebtedness outstanding under clause
(xx) below;

 

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

 

    65

     

    

 

 

(iii)          the
incurrence by the Company and the Guarantors of Indebtedness represented by (A) the Notes and the related Note Guarantees,
to be issued on the date of this Indenture (or to be issued in connection with the Rights Offering) and (B) any Additional
Notes and related Note Guarantees, as the case may be, including all Permitted Refinancing Indebtedness incurred to renew, refund,
refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (iii), provided that the aggregate outstanding
principal amount at any time under this clause (iii)(B),shall not exceed an amount equal to $50.0 million, less the aggregate principal
amount of any Notes issued in the Rights Offering; and provided, further, that fifty percent (50%) of proceeds raised in excess
of $35 million from the Rights Offering and any Additional Notes shall be used to make an offer to repurchase Notes at 100% of
the aggregate principal amount thereof;

 

(iv)          the
incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness represented by Capital Lease Obligations (other
than Deemed Capitalized Leases), mortgage financings or purchase money obligations, in each case, incurred for the purpose of financing
all or any part of the purchase price or cost of design, construction, installation or improvement of property, plant or equipment
used in the business of the Company or any of its Restricted Subsidiaries (whether through (a) the direct purchase of such
assets or (b) the purchase of the Capital Stock of a Person owning such assets (but no other material assets) the result of
which is that such Person becomes a Subsidiary of the Company or another Restricted Subsidiary) and related financing costs, 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 (iv), not to exceed $15.0 million at any time outstanding,
and in each case at arms-length and on market terms (as determined by an Officer of the Company in such Officer’s reasonable
discretion);

 

(v)           the
incurrence by the Company or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net
proceeds of which are used to renew, refund, refinance, replace, defease or discharge any Indebtedness (other than intercompany
Indebtedness) that was permitted by this Indenture to be incurred under Section 4.09(a) or clauses (ii), (iii), (iv),
(v) or (xii) of this Section 4.09(b);

 

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

 

(A)            if
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 unsecured and 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)            (1) 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 (2) 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 (vi);

 

    66

     

    

 

(vii)          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:

 

(A)            any
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
Company, will be deemed, in each case, to constitute an issuance of such preferred stock by such Restricted Subsidiary that was
not permitted by this clause (vii);

 

(viii)         the
incurrence by the Company or any of its Restricted Subsidiaries of Hedging Obligations in the ordinary course of business to protect
the Company and its Restricted Subsidiaries against bona fide risk arising out of fluctuation in interest rates, currency exchange
rates or commodity prices and not for speculative purposes;

 

(ix)            the
guarantee by the Company or any of the Guarantors of Indebtedness of the Company (excluding the guarantee of Indebtedness incurred
by a Foreign Subsidiary under clause (xxi) of this Section 4.09(b)) or a Restricted Subsidiary of the Company and the
guarantee by any Foreign Subsidiary of Indebtedness of another Foreign Subsidiary, in each case, to the extent that the guaranteed
Indebtedness was permitted to be incurred by another provision of this Section 4.09; provided that if the Indebtedness
being guaranteed is subordinated to or pari passu with the Notes, then the Note Guarantee must be subordinated or pari
passu, as applicable, to the same extent as the Indebtedness guaranteed;

 

(x)             the
incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness in respect of workers’ compensation claims,
self-insurance obligations and bankers’ acceptances in the ordinary course of business;

 

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

 

(xii)           the
incurrence by the Company or any of the Restricted Subsidiaries of Permitted Acquisition Indebtedness;

 

    67

     

    

 

(xiii)          the

in a transaction permitted by this Indenture, other than guarantees of Indebtedness incurred or assumed by any Person acquiring
all or any portion of such business, assets or Subsidiary for the purpose of financing such acquisition;

 

(xiv)         the
incurrence by the Company or any Restricted Subsidiary of Indebtedness provided that sufficient net proceeds thereof are promptly
deposited to defease or satisfy all of the Notes as described in Articles 8 or 12 hereof;

 

(xv)          the
incurrence by the Company or its Restricted Subsidiaries of Indebtedness consisting of the financing of insurance premiums in customary
amounts consistent with the operations and business of the Company and the Restricted Subsidiaries;

 

(xvi)         intercompany
Indebtedness between or among the Company and any of its Restricted Subsidiaries incurred in the ordinary course of business in
connection with cash pooling or other cash management arrangements;

 

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

 

(xviii)       [Intentionally
Omitted];

 

(xix)          letters
of credit and/or bank guarantees issued in the ordinary course of business by a financial institution other than a lender or Affiliate
of a lender under the Credit Agreement if the Company has reasonably determined that neither such lender or Affiliate is able to
issue such letter of credit or bank guaranty, up to a maximum total for all such letters of credit at any one time outstanding
of the lesser of (x) $10.0 million and (y) the difference between $85.0 million and the amount incurred and outstanding
under clauses (i) and (xix) of this Section 4.09(b);

 

(xx)           the
incurrence by the Company or any of its Restricted Subsidiaries of additional Indebtedness (excluding Second Lien Debt and Indebtedness
of the type described in clause (b)(iii)) or the issuance by the Company of additional Disqualified Stock in an aggregate principal
amount (or accreted value, as applicable) at any time outstanding, including all Permitted Refinancing Indebtedness incurred to
renew, refund, refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (xx), not to exceed of
the lesser of (x) $25.0 million and (y) the difference between $75.0 million and the amount incurred and outstanding
under clauses (i) and (xx) of this Section 4.09(b);

 

    68

     

    

 

(xxi)          the
incurrence of Indebtedness by Foreign Subsidiaries in an aggregate amount not to exceed $25.0 million; and

 

(xxii)         the
incurrence of Indebtedness secured on a pari passu or junior priority basis to the Notes, in an aggregate principal amount
outstanding equal to the amount of Notes redeemed on or prior to the date of such incurrence.

 

For purposes of determining
compliance with this Section 4.09, in the event that an item of Indebtedness meets the criteria of more than one of the categories
of Permitted Debt described in Section 4.09(b)(i) through Section 4.09(b)(xxii) above, or is entitled to be
incurred pursuant to Section 4.09(a), the Company will be permitted to divide, classify and reclassify such item of Indebtedness
on the date of its incurrence, or later redivide or reclassify all or a portion of such item of Indebtedness, in any manner that
complies with this Section 4.09. Indebtedness under Credit Facilities outstanding on the date on which Notes are first issued
and authenticated under this Indenture will be deemed to have been incurred on such date in reliance on the exception provided
by Section 4.09(b)(i). The accrual of interest or preferred stock dividends, the accretion or amortization of original issue
discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, the reclassification
of preferred stock as Indebtedness due to a change in accounting principles, and the payment of dividends on preferred stock or
Disqualified Stock in the form of additional shares of the same class of preferred stock or Disqualified Stock will not be deemed
to be an incurrence of Indebtedness or an issuance of preferred stock or Disqualified Stock for purposes of this Section 4.09;
provided, in each such case, that the amount thereof is included in Fixed Charges of the Company as accrued. For purposes
of determining compliance with any U.S. dollar-denominated restriction on the incurrence of Indebtedness, the U.S. dollar-equivalent
principal amount of Indebtedness denominated in a foreign currency shall be utilized, calculated based on the relevant currency
exchange rate in effect on the date such Indebtedness was incurred. 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.

 

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

 

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

 

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

 

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

 

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

 

    69

     

    

 

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

 

		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:

 

(i)             the
Company or any of its Restricted Subsidiaries (as the case may be) receives consideration at the time of the Asset Sale at least
equal to the Fair Market Value (measured as of the date of the definitive agreement with respect to such Asset Sale) of the assets
or Equity Interests issued or sold or otherwise disposed of; and

 

(ii)            at
least 85% of the consideration received in the Asset Sale by the Company or such Restricted Subsidiaries (measured as of the date
of the definitive agreement with respect to such Asset Sale) and all other Asset Sales since the Issue Date is in the form of cash
or 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, 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 forgiven or assumed by the transferee of any such assets pursuant to a customary novation or indemnity agreement that releases
the Company or such Restricted Subsidiary or indemnifies against further liability;

 

(B)           any
securities, notes or other obligations received by the Company or any such Restricted Subsidiary from such transferee that are,
within 90 days after the Asset Sale, converted by the Company or such Restricted Subsidiary into cash, to the extent of the cash
received in that conversion;

 

(C)           any
stock or assets of the kind referred to in Section 4.10(b)(ii) or (iv) hereof;

 

(D)          accounts
receivable of a business retained by the Company or any of its Restricted Subsidiaries, as the case may be, following the sale
of such business, provided that such accounts receivable do not have a payment date greater than 90 days from the date of the invoices
creating such accounts receivable and are not past due; and

 

(E)           Indebtedness
(other than contingent liabilities and liabilities that are by their terms subordinated to the Notes or a Note Guarantee) of any
Restricted Subsidiary that is no longer a Restricted Subsidiary as a result of such Asset Sale; provided that the Company
and each other Restricted Subsidiary are released from any Guarantee of such Indebtedness in connection with such Asset Sale;

 

    70

     

    

 

provided
that in the case of any Asset Sale pursuant to a condemnation, appropriation or similar taking, including by deed in
lieu of condemnation, such Asset Sale shall not be required to satisfy the requirements of Sections 4.10(a)(i) and 4.10(a)(ii) above.
Notwithstanding the preceding, the 85% limitation referred to above shall be deemed satisfied with respect to any Asset Sale in
which the cash or Cash Equivalents portions of the consideration received therefrom, determined in accordance with the preceding
provision on an after-tax basis, is equal to or greater than what the after-tax proceeds would have been had such Asset Sale complied
with the aforementioned 85% limitation.

 

(b)            Within
180 days after the receipt of any Net Proceeds from an Asset Sale, other than a Sale of Collateral, the Company or one or more
of its Restricted Subsidiaries may at its option apply cash in an amount equal to the amount of such Net Proceeds to any combination
of the following:

 

(i)             to
repay (or cash collateralize) (A) Priority Lien Obligations and, (B) to the extent required by the documents governing
such Indebtedness, Indebtedness permitted to be incurred pursuant to Section 4.09(b)(iv) hereof, provided that
such Indebtedness was incurred for the purpose of financing all or part of the purchase price or cost of the design, construction,
installation or improvement of such assets;

 

(ii)            to
acquire all or substantially all of the assets of, or any 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;

 

(iii)           to
make capital expenditures in the Permitted Business, including investments in multi- client data libraries; or

 

(iv)           to
acquire other assets that are not classified as current assets under GAAP and that are used or useful in a Permitted Business.

 

The requirement of clause (ii) or
(iv) of this Section 4.10(b) shall be deemed to be satisfied if a bona fide binding contract committing to make
the investment referred to therein is entered into by the Company or any of its Restricted Subsidiaries with a Person other than
an Affiliate of the Company within the time period specified in the preceding paragraph and such Net Proceeds are subsequently
applied in accordance with such contract within 180 days following the date such agreement is entered into. Pending the final application
of any Net Proceeds, the Company (or any Restricted Subsidiary) may invest the Net Proceeds in any manner that is not prohibited
by this Indenture.

 

(c)            Within
180 days after the receipt of any Net Proceeds from an Asset Sale that constitutes a Sale of Collateral, the Company (or the Restricted
Subsidiary that owned those assets, as the case may be) may at its option apply cash in an amount equal to the amount of such Net
Proceeds to any combination of the following: (1) to purchase or invest in other long-term assets that would constitute Collateral;
(2) to repay (or cash collateralize) Priority Lien Obligations or (3) to make capital expenditures in the Permitted Business,
including investments in multi-client data libraries in each case, comprising Collateral; provided, however, that the aggregate
amount of Net Proceeds that may be applied or invested pursuant to clauses (1) through (3) above shall not exceed $25.0
million in the aggregate during any fiscal year.

 

    71

     

    

 

(d)            All
of the Net Proceeds from an Asset Sale that constitutes a Sale of Collateral shall be deposited directly into the Collateral Account;
provided, that the Company and the Restricted Subsidiaries will not be required to cause any Net Proceeds to be held in the Collateral
Account except to the extent that the aggregate amount of Net Proceeds from all Asset Sales that constitute a Sale of Collateral
which are not held in the Collateral Account exceeds $25.0 million in the aggregate during any fiscal year. Any Net Proceeds from
Asset Sales that are not applied or invested as provided in Section 4.10(b) hereof will constitute “Excess Proceeds.”
When the aggregate amount of Excess Proceeds exceeds $1.0 million, the Company may (and when the Excess Proceeds exceeds $10.0
million shall), within five days thereof, to the extent permitted by the Intercreditor Agreement and the Credit Agreement, each
as in effect as of the Issue Date, make an Asset Sale Offer to all Holders of Notes and all holders of Second Lien Debt containing
provisions similar to those set forth in this Indenture with respect to offers to purchase, prepay or redeem with the proceeds
of sales of assets in accordance with Section 3.09 hereof to purchase, prepay or redeem the maximum principal amount of Notes
and such other Second Lien Debt (plus all accrued interest on the Indebtedness and the amount of all fees and expenses, including
premiums, incurred in connection therewith) that may be purchased, prepaid or redeemed out of the Excess Proceeds. The offer price
in any Asset Sale Offer will be equal to 100% of the principal amount, plus accrued and unpaid interest, if any, to the date of
purchase, prepayment or redemption, subject to the rights of Holders of Notes on the relevant record date to receive interest due
on the relevant interest payment date, and will be payable in cash. If any Excess Proceeds remain after consummation of an Asset
Sale Offer (or expiration of the offer if no Holder accepts), 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 Second Lien Debt tendered in (or required to
be prepaid or redeemed in connection with) such Asset Sale Offer exceeds the amount of Excess Proceeds, the Company will select
the Notes and such other Second Lien Debt to be purchased on a pro rata basis (except that any Notes represented by a note
in global form will be selected by such method as DTC or its nominee or successor may require or a method that most nearly approximates
pro rata selection unless otherwise required by law), based on the amounts tendered or required to be prepaid or redeemed (with
such adjustments as may be deemed appropriate by the Company so that only Notes in denominations of $1,000, or an integral multiple
of $1,000 in excess thereof, will be purchased). Upon completion of each Asset Sale Offer (or expiration of the offer if no holder
accepts), the amount of Excess Proceeds will be reset at zero.

 

(e)            The
Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations
thereunder to the extent those laws and regulations are applicable in connection with each repurchase of Notes pursuant to a Change
of Control Offer or an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with
the provisions of Section 3.09 hereof 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 hereof 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 $1.0 million, unless:

 

    72

     

    

 

(i)             the
Affiliate Transaction is on terms that are no less favorable to the Company or the relevant Restricted Subsidiary than those that
could have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated Person or,
if in the good faith judgment of the Company’s Board of Directors, no comparable transaction is available with which to compare
such Affiliate Transaction, such Affiliate Transaction is otherwise fair to the Company or the relevant Restricted Subsidiary from
a financial point of view; and

 

(ii)           the
Company delivers to the Trustee:

 

(A)            with
respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of
$20.0 million, an Officers’ Certificate certifying that such Affiliate Transaction or series of related Affiliate Transactions
complies with this covenant; and

 

(B)             with
respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of
$40.0 million, a resolution of the Board of Directors of the Company set forth in an Officers’ Certificate certifying that
such Affiliate Transaction or series of related Affiliate Transactions complies with this covenant and that such Affiliate Transaction
or series of related Affiliate Transactions has been approved by a majority of the disinterested members of the Board of Directors
of the 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:

 

(i)             any
employment agreement or arrangement, equity award, equity option or equity appreciation agreement or plan, employee benefit plan,
officer or director indemnification agreement, severance agreement or any similar arrangement entered into by the Company or any
of its Restricted Subsidiaries in the ordinary course of business and payments, awards, grants or issuances pursuant thereto;

 

(ii)            transactions
between or among the Company and/or its Restricted Subsidiaries (or an entity that becomes a Restricted Subsidiary as a result
of such transactions);

 

(iii)           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;

 

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

 

    73

     

    

 

(v)           any
issuance, dividend or distribution of Equity Interests (other than Disqualified Stock) of the Company to, or receipt of capital
contributions from, Affiliates of the Company and the granting of registration rights and other customary rights in connection
therewith;

 

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

 

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

 

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

 

(ix)            loans
or advances to employees in the ordinary course of business not to exceed $5.0 million in the aggregate at any one time outstanding;

 

(x)             transactions
with Unrestricted Subsidiaries, joint ventures, customers, clients, suppliers or purchasers or sellers of goods or services, or
lessors or lessees of property, in each case in the ordinary course of business and otherwise in compliance with the terms of this
Indenture which are, in the aggregate (taking into account all the costs and benefits associated with such transactions), not materially
less favorable to the Company and its Restricted Subsidiaries than those that would have been obtained in a comparable transaction
by the Company or such Restricted Subsidiary with an unrelated person, in the good faith determination of the Company’s Board
of Directors or any Officer of the Company involved in or otherwise familiar with such transaction, or are on terms at least as
favorable as might reasonably have been obtained at such time from an unaffiliated party;

 

(xi)            transactions
between the Company or any of its Restricted Subsidiaries and any Person that would not otherwise constitute an Affiliate Transaction
except for the fact that one director of such other Person is also a director of the Company or such Restricted Subsidiary, as
applicable; provided that such director abstains from voting as a director of the Company or such Restricted Subsidiary,
as applicable, on any matter involving such other Person;

 

(xii)           the
existence of, and the performance of obligations of the Company or any of its Restricted Subsidiaries under the terms of, any written
agreement to which the Company or any of its Restricted Subsidiaries is a party on the date of this Indenture, as these agreements
may be amended, modified or supplemented from time to time; provided, however, that any amendment, modification or
supplement entered into after the date of this Indenture will be permitted to the extent that its terms are not materially more
disadvantageous, taken as a whole, to the Holders of the Notes than the terms of the agreements in effect on the date of this Indenture
(as conclusively evidenced by a resolution of the Board of Directors of the Company);

 

    74

     

    

 

(xiii)         transactions
entered into by a Person prior to the time such Person becomes a Restricted Subsidiary or is merged or consolidated into the Company
or a Restricted Subsidiary (provided that such transaction is not entered into in contemplation of such merger or consolidation);

 

(xiv)         dividends
and distributions to the Company and its Restricted Subsidiaries by any Unrestricted Subsidiary or joint venture;

 

(xv)          any
transaction where the only consideration paid by the Company or Restricted Subsidiary is Equity Interests of the Company (other
than Disqualified Stock); and

 

(xvi)         (A) guarantees
by the Company or any of its Restricted Subsidiaries of performance of obligations of the Company’s Unrestricted Subsidiaries
or joint ventures in the ordinary course of business, except for guarantees of Indebtedness of Unrestricted Subsidiaries in respect
of borrowed money, and (B) pledges by the Company or any Restricted Subsidiary of the Company of Equity Interests in Unrestricted
Subsidiaries or joint ventures for the benefit of lenders or other creditors of the Company’s Unrestricted Subsidiaries or
joint ventures, in each case as permitted by the terms of this Indenture.

 

		Section
                            4.12	Liens.

 

The Company will not,
and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, assume or suffer to exist any
Lien of any kind securing Indebtedness, Attributable Debt or trade payables on any asset now owned or hereafter acquired, except
Permitted Liens.

 

		Section
                            4.13	Corporate
Existence.

 

Subject to Article 5
and Section 11.04 hereof, the Company shall do or cause to be done all things necessary to preserve and keep in full force
and effect:

 

(i)             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

 

(ii)            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 of the Company 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.

 

    75

     

    

 

		Section 4.14	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 $1,000 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 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 ten
days following any Change of Control, the Company will mail a notice to each Holder describing the transaction or transactions
that constitute the Change of Control and stating:

 

(i)             that
the Change of Control Offer is being made pursuant to this Section 4.14 and that all Notes tendered will be accepted for payment;

 

(ii)            the
purchase price and the purchase date, which date shall be no earlier than 30 days and no later than 60 days from the date such
notice is mailed (the “Change of Control Payment Date”);

 

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

 

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

 

(v)            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;

 

(vi)           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 telegram, telex, facsimile transmission or letter setting forth the
name of the Holder, the principal amount of Notes delivered for purchase, and a statement that such Holder is withdrawing its election
to have the Notes purchased; and

 

(vii)          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 $1,000 in principal amount or an integral multiple of $1,000
in excess thereof.

 

The Company will comply
with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the
extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control.
To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 4.14,
the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations
under this Section 4.14 by virtue of such compliance.

 

    76

     

    

 

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

 

(i)             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

 

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

 

The Paying Agent will
promptly mail (but in any case not later than five days after the Change of Control Payment Date) to each Holder of Notes properly
tendered the Change of Control Payment for such Notes (or, if all of the Notes are then in global form, make such payment through
the facilities of DTC), and the Trustee will, upon receipt of an Authentication Order, promptly authenticate and mail (or cause
to be transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered,
if any. 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 4.14, 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 4.14 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 hereof, and all conditions
precedent to such redemption have been satisfied or waived, unless and until there is a default in payment of the applicable redemption
price or (3) in connection with or in contemplation of any Change of Control, the Company has made an offer to purchase (an
“Alternate Offer”) any and all Notes validly tendered at a cash price equal to or higher than the Change of
Control Payment and has purchased all Notes properly tendered in accordance with the terms of such Alternate Offer. Notwithstanding
anything to the contrary contained herein, a Change of Control Offer or Alternate Offer may be made in advance of a Change of Control,
conditioned upon the consummation of such Change of Control, if a definitive agreement is in place for the Change of Control at
the time the Change of Control Offer or Alternate Offer is made.

 

(d)            Notwithstanding
anything to the contrary contained herein, a Change of Control Offer or Alternate Offer may be made in advance of a Change of Control,
conditioned upon the consummation of such Change of Control, if a definitive agreement is in place for the Change of Control at
the time the Change of Control Offer or Alternate Offer is made.

 

    77

     

    

 

(e)            In
the event that Holders of not less than 90% in aggregate principal amount of the outstanding Notes accept a Change of Control Offer
or Alternate Offer and the Company (or any third party making such Change of Control Offer or Alternate Offer in lieu of the Company)
purchases all of the Notes held by such Holders, the Company will have the right, upon not less than 30 nor more than 60 days’
prior notice to the Trustee and the Holders, given not more than 30 days following the purchase pursuant to the Change of Control
Offer or Alternate Offer, to redeem all of the Notes that remain outstanding following such purchase at a redemption price equal
to the Change of Control Payment plus, to the extent not included in the Change of Control Payment, accrued and unpaid interest
on the Notes that remain outstanding, to the date of redemption (subject to the right of Holders of record on the relevant record
date to receive interest due on an interest payment date that is on or prior to the redemption date). Any redemption pursuant to
this Section 4.14(e) shall be made pursuant to the provisions of Sections 3.01 through 3.06 hereof.

 

		Section 4.15	Additional
Note Guarantees.

 

If the Company or any
of its Restricted Subsidiaries acquires or creates another Domestic Subsidiary (other than an Immaterial Subsidiary) or any other
Restricted Subsidiary guarantees Indebtedness of the Company or any Domestic Subsidiary in excess of a De Minimis Guaranteed Amount,
then such Subsidiary will become a Guarantor and execute a supplemental indenture and deliver an Opinion of Counsel satisfactory
to the Trustee within 30 Business Days of the date on which it was acquired or created or on which it Guaranteed such Indebtedness.
The form of such supplemental indenture is attached as Exhibit F hereto.

 

		Section 4.16	Designation
of Restricted and Unrestricted Subsidiaries.

 

The Board of Directors
of the Company may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if that designation would not cause a Default
or an Event of Default. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate Fair Market Value
of all outstanding Investments owned by the Company and its Restricted Subsidiaries in the Subsidiary designated as an Unrestricted
Subsidiary will be deemed to be either an Investment made as of the time of the designation and will reduce the amount available
for Restricted Payments under Section 4.07 hereof or represent a Permitted Investment under one or more clauses of the definition
of Permitted Investments, as determined by the Company. That designation will only be permitted if the Investment would be permitted
at that time and if the Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. The Board of Directors
of the Company may redesignate any Unrestricted Subsidiary to be a Restricted Subsidiary if that redesignation would not cause
a Default or an Event of Default.

 

    78

     

    

 

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 Officers’ Certificate certifying
that such designation complied with the preceding conditions and was permitted by Section 4.07 hereof. In the case of any
designation by the Company of a Person as an Unrestricted Subsidiary on the first day that such Person is a Subsidiary of the Company
in accordance with the provisions of this Indenture, such designation shall be deemed to have occurred for all purposes of this
Indenture simultaneously with, and automatically upon, such Person becoming a Subsidiary. 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 of the Company; 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 (a) 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 applicable reference period; and (b) no Default
or Event of Default would be in existence following such designation; provided, further, that (i) upon a redesignation
of an Unrestricted Subsidiary as a Restricted Subsidiary, the Company shall be deemed to continue to have a permanent Investment
in such Subsidiary at the time of redesignation in an amount (if positive) equal to (x) the Company’s Investment in
such Subsidiary at the time of such redesignation less (y) the portion (proportionate to the Company’s equity interest
in such Subsidiary) of the Fair Market Value of the net assets of such Subsidiary at the time of such redesignation, and (ii) any
property transferred to or from an Unrestricted Subsidiary shall be valued at its Fair Market Value (as determined in good faith
by the Company) at the time of such transfer.

 

Neither the Company
nor any Restricted Subsidiary will transfer the ownership of any intellectual property that is material to the Company and its
Restricted Subsidiaries taken as a whole to an Unrestricted Subsidiary.

 

		Section 4.17	Covenant
Suspension.

 

(a)            If
on any date following the date of this Indenture (i) the Notes are rated Baa3 or better by Moody’s and BBB- or better
by S&P (or, if either such entity ceases to rate the Notes for reasons outside of the control of the Company, the equivalent
investment grade credit rating from any other “nationally recognized statistical rating organization” registered under
Section 15E of the Exchange Act selected by the Company as a replacement agency) (“Investment Grade”) and
(ii) no Default or Event of Default shall have occurred and be continuing (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 subject to the provisions of the following paragraph, Sections 4.07, 4.08, 4.09, 4.10 (provided that those
provisions relating to the Sale of Collateral and the application of the proceeds therefrom shall remain in full force and effect
and shall not be suspended), 4.11, 4.16 and 5.01(iv)(A) hereof shall be suspended (collectively, the “Suspended Covenants”).

 

(b)            During
any period that the Suspended Covenants have been suspended as a result of a Covenant Suspension Event, the Company’s Board
of Directors may not designate any of its Subsidiaries as Unrestricted Subsidiaries pursuant to Section 4.16 hereof or the
second paragraph of the definition of Unrestricted Subsidiary.

 

(c)             Notwithstanding
the foregoing, if on any subsequent date, the Notes cease to maintain Investment Grade ratings, the Suspended Covenants will be
reinstituted as of and from the date of such rating decline (a “Reversion Date”). Calculations under the reinstated
Section 4.07 will be made as if Section 4.07 had been in effect since the date of this Indenture except that no default
will be deemed to have occurred solely by reason of a Restricted Payment made while Section 4.07 was suspended.

 

    79

     

    

 

(d)            Upon
the occurrence of a Covenant Suspension Event or a Reversion Date, the Company shall provide written notice to the Trustee, the
Collateral Agent and the Holders, and file with the Trustee an Officers’ Certificate certifying that such suspension or reversion
complied with the foregoing provisions.

 

(e)            The
Trustee shall not be responsible or liable for monitoring the ratings of the Notes or otherwise determining or confirming whether
any covenants are suspended or reinstituted pursuant to the above or provide notice to the Holders of Notes of any Covenant Suspension
Event or Reversion Date.

 

		Section 4.18	Further
Assurances; Insurance.

 

(a)            The
Company and each of the other Guarantors shall do or cause to be done all acts and things that may be necessary or desirable, or
that the Collateral Agent, acting in accordance with the Intercreditor Agreement, from time to time may reasonably request, to
assure and confirm that the Collateral Agent holds, for the benefit of the Second Lien Secured Parties, duly created and enforceable
and perfected Second Liens upon the Collateral (including any property or assets that are acquired or otherwise become Collateral
after the Notes are issued), in each case, as contemplated by, and with the Lien priority required under, the Second Lien Documents.

 

(b)            If
necessary or desirable or upon the request of the Collateral Agent, acting at the direction of Holders, or any Second Lien Representative,
acting in accordance with the Intercreditor Agreement, at any time and from time to time, the Company and each of the other Guarantors
shall promptly execute, acknowledge and deliver such security documents, instruments, certificates, notices and other documents,
and take such other actions as shall be reasonably necessary or desirable to create, perfect, protect, assure or enforce the Liens
and benefits intended to be conferred, in each case as contemplated by the Second Lien Documents for the benefit of the holders
of Second Lien Obligations.

 

(c)            The
Company and the other Guarantors will:

 

(i)             keep
their properties adequately insured at all times by financially sound and reputable insurers;

 

(ii)            maintain
such other insurance, to such extent and against such risks (and with such deductibles, retentions and exclusions), including fire
and other risks insured against by extended coverage and coverage for acts of terrorism, as is customary with companies in the
same or similar businesses operating in the same or similar locations, including public liability insurance against claims for
personal injury or death or property damage occurring upon, in, about or in connection with the use of any properties owned, occupied
or controlled by them;

 

(iii)           maintain
such other insurance as may be required by law; and

  

    80

     

    

 

(iv)           maintain
such other insurance as may be required by the Security Documents. 

 

(d)            Upon
the request of the Collateral Agent, acting upon the request of Holders, the Company and the other Guarantors shall furnish to
the Collateral Agent full information as to their property and liability insurance carriers, certified as true and correct. Holders
of Second Lien Obligations, as a class, shall be named as additional insureds, with a waiver of subrogation, on all insurance policies
of the Company and the other Guarantors covering the Collateral and the Collateral Agent shall be named as loss payee, with 30
days’ notice of cancellation or material change, on all property and casualty insurance policies of the Company and the other
Guarantors covering the Collateral.

 

		Section 4.19	Impairment
of Security Interest.

 

Except as permitted
by the Intercreditor Agreement, the Company shall not, and shall not permit any of its Restricted Subsidiaries to, take or knowingly
or negligently omit to take, any action which action or omission might or would have the result of materially impairing the security
interest with respect to the Collateral for the benefit of the Trustee, the Collateral Agent and the other Second Lien Secured
Parties, and the Company shall not, and shall not permit any of the Restricted Subsidiaries to, except as permitted under the terms
of this Indenture, grant to any Person other than the Collateral Agent, for the benefit of itself, the Trustee and the other Second
Lien Secured Parties and the other beneficiaries described in the Security Documents, any interest whatsoever in any of the Collateral.

 

		Section 4.20	After-Acquired
Property.

 

Promptly following
the acquisition by the Company or any Guarantor of any After-Acquired Property, the Company or such Guarantor shall promptly execute
and deliver such mortgages, deeds of trust, security instruments, financing statements and certificates and Opinions of Counsel
as shall be reasonably necessary to vest in the Collateral Agent, for the benefit of the Second Lien Secured Parties, a perfected
second priority security interest in such After-Acquired Property and to have such After-Acquired Property added to the Collateral
and thereupon all provisions of the indenture relating to the Collateral shall be deemed to relate to such After-Acquired Property
to the same extent and with the same force and effect.

 

		Section 4.21	Limitation
on Layered Indebtedness.

 

Notwithstanding anything
in this Indenture to the contrary, the Company shall not, and will not permit any Guarantor to incur any Indebtedness (including
Permitted Debt) that is contractually subordinated either in right of payment or in respect of the grant or the application of
proceeds of Collateral to any other Indebtedness of the Company or such Guarantor (including by way of “last out” tranches
but excluding the customary waterfall payments among protective advances, swing line advances, advances and Hedging Obligations
constituting the same tranche of Priority Lien Debt, such as those set forth in Section 11.5 of the Credit Agreement), unless
such Indebtedness is also contractually subordinated in right of payment or in respect of the grant and the application of proceeds
of Collateral, as the case may be, to the Notes and the applicable Guarantee on substantially identical terms. For the avoidance
of doubt, the foregoing shall not prohibit any Permitted Refinancing of the Credit Agreement with other Priority Lien Debt.

referring to the “Company” shall refer instead to the successor Person and not to the Company), and may exercise every
right and power of the Company under this Indenture with the same effect as if such successor Person had been named as the Company

premium on, if any, 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 hereof.

 

ARTICLE 6

DEFAULTS AND REMEDIES

 

		Section 6.01	Events
of Default.

 

Each of the following
is an “Event of Default”:

 

(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 Sections 4.07, 4.09, 4.10, 4.14, and 5.01;

 

(iv)           failure
by the Company or any of its Restricted Subsidiaries for 60 days after notice to the Company by the Trustee or the Holders of at
least 25% in aggregate principal amount of the Notes then outstanding voting as a single class to comply with any of the other
agreements in this Indenture or the Security Documents or (B) failure by the Company for 180 days after notice from the Trustee
or Holders of at least 25% in aggregate principal amount of the Notes then outstanding to comply with the provisions of Section 4.03

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

 

    83

     

    

 

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

 

(B)             results
in the acceleration of such Indebtedness prior to its Stated 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

if, prior to any acceleration of the Notes, (x) any such Payment Default is cured or waived, (y) any such acceleration
is rescinded, or (z) such Indebtedness is repaid within 10 Business Days commencing upon the end of any applicable grace period
for such Payment Default or the occurrence of such acceleration, as the case may be, any Default or Event of Default (but not any
acceleration of the Notes) caused by such Payment Default or acceleration shall be automatically rescinded, so long as such rescission

provided that it will not be an Event of Default under this clause (vii)(A) if the sole result of the failure of one
or more security documents to be fully enforceable is that any Second Lien purported to be granted under such Security Documents
on Collateral, individually or in the aggregate, having a Fair Market Value of not more than $10.0 million ceases to be an enforceable
and perfected second priority Lien, subject only to Permitted Prior Liens;

 

(B)             any
Second Lien purported to be granted under any security document on Collateral, individually or in the aggregate, having a Fair

Section 6.02     Acceleration.

 

In the case of an Event
of Default set forth in clause (viii) or (ix) 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.

 

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

 

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

 

Section 6.03     Other
Remedies.

 

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

 

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

 

Section 6.04     Waiver
of Past Defaults.

 

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

 

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 or that the Trustee determines may be unduly prejudicial to the
rights of other Holders of Notes or that may involve the Trustee in liability or expense.

 

    86

     

    

 

Section 6.06     Limitation
on Suits.

 

Except to enforce the
right to receive payment of principal, premium, if any, or interest, when due, no Holder of a Note may pursue any remedy with respect
to this Indenture or the Notes unless:

 

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

 

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

 

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

 

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

 

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

 

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

 

Section 6.07     Rights
of Holders of Notes to Receive Payment.

 

Notwithstanding any
other provision of this Indenture, the right of any Holder of a Note to receive payment of principal of, premium on, if any, or
interest 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; provided that a Holder shall not have the right to institute any such suit for the enforcement
of payment if and to the extent that the institution or prosecution thereof or the entry of judgment therein would, under applicable
law, result in the surrender, impairment, waiver or loss of the Lien of this Indenture upon any property subject to such Lien.

 

Section 6.08     Collection
Suit by Trustee and Collateral Agent.

 

If an Event of Default
specified in Section 6.01(i) or (ii) hereof occurs and is continuing, the Trustee or the Collateral Agent is authorized

the case of the Collateral Agent, as collateral agent on behalf of the Holders, in each case against the Company for the whole
amount of principal of, premium on, if any, and interest remaining unpaid on the Notes and, to the extent lawful, interest on overdue
principal and interest and such further amount as shall be sufficient to cover the costs and expenses of collection, including
the reasonable compensation, expenses, disbursements and advances of the Trustee, the Collateral Agent and their respective agents
and counsel.

Section 6.09     Trustee
May File Proofs of Claim.

Collateral Agent, and in the event that the Trustee or the Collateral Agent shall consent to the making of such payments directly
to the Holders, to pay to the Trustee or the Collateral Agent, as applicable, any amount due to it for the reasonable compensation,
expenses, disbursements and advances of the Trustee, the Collateral Agent and their respective agents and counsel, and any other
amounts due the Trustee or the Collateral Agent under Section 7.07 hereof. To the extent that the payment of any such compensation,
expenses, disbursements and advances of the Trustee, the Collateral Agent and their respective agents and counsel, and any other
amounts due the Trustee or the Collateral Agent under Section 7.07 hereof out of the estate in any such proceeding, shall
be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions,
dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation
or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee
or the Collateral Agent 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 or the Collateral Agent
to vote in respect of the claim of any Holder in any such proceeding.

 

Section 6.10     Priorities.

 

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

In any suit for the
enforcement of any right or remedy under this Indenture or in any suit against the Trustee or the Collateral Agent, as the case
may be, for any action taken or omitted by it as a Trustee or the Collateral Agent, a court in its discretion may require the filing

of Trustee.

 

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

 

(b)     Except
during the continuance of an Event of Default of which a Responsible Officer of the Trustee has written notice:

 

(i)            the
duties of the Trustee will be determined solely by the express provisions of this Indenture and the Trustee need perform only those
duties that are specifically set forth in this Indenture and no others, and no implied covenants or obligations shall be read into
this Indenture against the Trustee; and

 

(ii)           the
Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates
or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, in the case of any such certificates
or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee will examine the
certificates and opinions to determine whether or not they conform to the requirements of this Indenture (but need not confirm
or investigate the accuracy of any mathematical calculations or other facts stated therein).

 

    89

     

    

 

(c)            The
Trustee may not be relieved from liabilities for its own grossly negligent action, its own grossly negligent failure to act, or
its own willful misconduct, in each case as determined by a court of competent jurisdiction pursuant to a final and non-appealable
decision, except that:

 

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

 

(ii)           the
Trustee will not be liable for any error of judgment made in good faith by a Responsible Officer, unless it is proved in a court
of competent jurisdiction in a final and non-appealable decision that the Trustee was grossly negligent in ascertaining the pertinent
facts; and

 

(iii)          the
Trustee will not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received
by it from the Company or a majority of Holders (or such other lower or greater amount required under the Note Documents) in accordance
with the Note Documents.

 

(d)            Whether
or not therein expressly so provided, every provision of this Indenture that in any way relates to the Trustee is subject to this
Article 7.

 

(e)            No
provision of this Indenture will require the Trustee to expend or risk its own funds or incur any liability. The Trustee will be

Trustee will not be liable for interest on any money received by it except as the Trustee may agree in writing with the Company.

fact or matter stated in the document and may conclusively rely as to the truth of the statements and the correctness of the opinions
expressed therein.

 

(b)            Before
the Trustee acts or refrains from acting, it may require an Officers’ Certificate or an Opinion of Counsel or both. The Trustee

of Counsel. As to any fact or matter the manner of ascertainment of which is not specifically described herein, the Trustee shall
be entitled to receive and may for all purposes hereof conclusively rely on a certificate, signed by an officer of any duly authorized
Person, as to such fact or matter, and such certificate shall constitute full protection to the Trustee for any action taken or
omitted to be taken by it in good faith in reliance thereon. The Trustee may consult with counsel and the advice of such counsel
or any Opinion of Counsel will be full and complete authorization and protection from liability in respect of any action taken,
suffered or omitted by it hereunder in good faith and in reliance thereon.

Trustee will be under no obligation to exercise any of the rights or powers vested in it by this Indenture or any other Note Document
at the request or direction of any of the Holders unless such Holders have offered to the Trustee indemnity or security satisfactory
to the Trustee against the losses, liabilities, costs and expenses that might be incurred by it in compliance with such request
or direction.

 

(g)           The
Trustee may request that the Company deliver an Officers’ Certificate setting forth the names of individuals and/or titles
of Officers authorized at such time to take specified actions pursuant to the Note Documents.

 

(h)           The
Company shall provide prompt written notice to the Trustee of any change to its fiscal year (it being expressly understood that
the failure to provide such notice to the Trustee shall not be deemed a Default or Event of Default under this Indenture).

 

(i)           The
Trustee shall not be deemed to have notice of any Default or Event of Default unless a Responsible Officer of the Trustee has received
written notice of any event which is in fact such a Default is received by the Trustee at the Corporate Trust Office of the Trustee,
and such notice references the Notes and this Indenture. For purposes of any determination as to whether a Responsible Officer
of the Trustee shall be deemed to have actual knowledge of any of the foregoing events, the Trustee shall have no obligation to
inquire into, or investigate as to, the occurrence of any such event.

rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be
indemnified, are extended to, and shall be enforceable by (i) the Trustee in each of its capacities (including as an Agent)
hereunder and under the Note Documents and (ii) the entity serving as the Trustee in each of its capacities hereunder and
in each of its capacities as under any other Note Document or any related document whether or not specifically set forth therein,
and each agent, custodian and other Person employed to act hereunder or thereunder; provided that during an Event of Default only
the Trustee, and not any Agent or agent, shall be subject to the prudent person standard. The foregoing shall survive the resignation

(o)          Each
Holder, by its acceptance of a Note hereunder, represents that it has, independently and without reliance upon the Trustee or any
other Person, and based on such documents and information as it has deemed appropriate, made its own investment decision in respect
of the Notes. Each Holder also represents that it will, independently and without reliance upon the Trustee or any other Person,
and based on such documents and information as it shall deem appropriate at the time, continue to make its own decisions in taking
or not taking action under this Indenture and in connection with the Notes. Except for notices, reports and other documents expressly

the Note Documents or any other related document.

 

(u)            The
Trustee shall not be required to take any action under any Note Document or any related document if taking such action (A) would

qualify to do business in any jurisdiction where it is not then so qualified.

 

(v)            In

secure the obligations owed to the Trustee hereunder, the Trustee shall have a lien prior on all money or property held or collected

Rights of Trustee.

individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Company or any Affiliate
of the Company with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting
interest (as defined in the TIA) it must eliminate such conflict within 90 days, apply to the SEC for permission to continue as

The Trustee is also subject to Sections 7.10 and 7.11 hereof.

If a Default or Event
of Default occurs and is continuing and a Responsible Officer of the Trustee receives written notice of the same, the Trustee shall
send to Holders of Notes, with a copy to the Collateral Agent, a notice of the Default or Event of Default within 90 days after
it occurs or within 15 Business Days after it received written notice, if later than 90 days after occurrence. Except in the case
of a Default or Event of Default in payment of principal of, premium on, if any, or interest on, any Note, the Trustee may withhold
the notice if and so long as the Trustee in good faith determines that withholding the notice is in the interests of the Holders
of the Notes.

 

Section 7.06    Reports
by Trustee to Holders of the Notes.

 

(a)     Within
60 days after each November 15 beginning with the November 15 following the date of this Indenture, and for so long as
Notes remain outstanding, the Trustee will mail to the Holders of the Notes a brief report dated as of such reporting date that
complies with TIA §313(a) (but if no event described in TIA §313(a) has occurred within the twelve months preceding
the reporting date, no report need be transmitted). The Trustee also will comply with TIA §313(b)(2). The Trustee will also
transmit by mail all reports as required by TIA §313(c).

 

(b)     A
copy of each report at the time of its mailing to the Holders of Notes will be mailed by the Trustee to the Company and filed with
the SEC and each stock exchange on which the Notes are listed in accordance with TIA §313(d). The Company will promptly notify
the Trustee, in writing, when the Notes are listed on any stock exchange or of any delisting thereof.

Section 7.07     Compensation
and Indemnity.

 

(a)     The
Company will pay to the Trustee and the Collateral Agent (and together with their respective officers, directors, employees, representatives,
attorneys and agents, the “Indemnified Parties”, and each, an “Indemnified Party”) from time
to time such compensation as agreed to in a separate fee agreement for its acceptance of this Indenture, the Security Documents
and services related thereto, hereunder and thereunder. The Trustee’s compensation will not be limited by any law on compensation
of a trustee of an express trust. The Company and the Guarantors, on a joint and several basis, will reimburse each Indemnified
Party 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, but are not limited to, costs of collection, costs of preparing and reviewing reports,
certificates and other documents, costs of preparation and mailing of notices to Holders and the reasonable compensation, costs
disbursements and expenses of each Indemnified Party’s agents and counsel.

 

(b)     The
Company and the Guarantors will indemnify, defend and hold harmless, on a joint and several basis, each Indemnified Party against
any and all losses, liabilities or expenses incurred by it arising out of or in connection with the acceptance or administration
of its duties under this Indenture or the other Note Documents, including the costs and expenses of enforcing this Indenture against
the Company and the Guarantors (including this Section 7.07) and defending itself against 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 under the Note Documents, except to the extent any such loss, liability or expense may be attributable to
its gross negligence or willful misconduct as proven in a court of competent jurisdiction in a final and non-appealable decision.
An Indemnified Party will notify the Company promptly of any claim for which it may seek indemnity. Failure by an Indemnified Party
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 subject Indemnified Party will cooperate in the defense. An Indemnified Party 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 and neither the Company nor
any Guarantor may agree to any settlement without consent of the Indemnified Parties, which consent will not be unreasonably withheld.

 

(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 termination of the Note Documents or earlier resignation or removal of the Trustee or any Agent, as applicable.

 

(d)     To
secure the Company’s and the Guarantors’ payment obligations in this Section 7.07, each Indemnified Party will
have a Lien prior to the Notes on all money or property held or collected by the Trustee, in its capacity as trustee, or the Collateral
Agent, in its capacity as collateral agent, except, in the case of the Trustee, that held in trust to pay principal of, premium
on, if any, or interest on, particular Notes. Such Lien will survive the satisfaction and discharge of this Indenture or earlier
resignation or removal of the Trustee.

 

    95

     

    

 

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

 

(f)      The
Trustee will comply with the provisions of TIA §313(b)(2) to the extent applicable.

 

Section 7.08     Replacement
of Trustee.

 

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

 

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

 

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

 

(ii)           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;

 

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

 

(iv)          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,
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
hereof, such Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor
Trustee.

 

(f)      A
successor Trustee will deliver a written acceptance of its appointment to the retiring Trustee and to the 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 mail a notice of its succession to Holders.

 

    96

     

    

 

The retiring Trustee will promptly transfer all property held by it as Trustee to the successor Trustee; provided all sums
owing to the Trustee hereunder have been paid and subject to the Lien provided for in Section 7.07 hereof. Notwithstanding
replacement of the Trustee pursuant to this Section 7.08, the Company’s obligations under Section 7.07 hereof
will continue for the benefit of the retiring Trustee.

 

Section 7.09     Successor
Trustee by Merger, etc.

 

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

 

Section 7.10     Eligibility;
Disqualification.

 

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

 

This Indenture will
always have a Trustee who satisfies the requirements of TIA §310(a)(1), (2) and (5). The Trustee is subject to TIA §310(b).

 

Section 7.11     Preferential
Collection of Claims Against Company.

 

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

 

Section 7.12     Collateral
Agent.

 

References to the Trustee
in Sections 7.01(b) through (f) (“Duties of Trustee”), 7.02 (“Rights of Trustee”), 7.03 (“Individual
Rights of Trustee”), 7.04 (“Trustee’s Disclaimer”), 7.07 (“Compensation and Indemnity”), 7.08
(“Replacement of Trustee”) and 7.09 (“Successor Trustee by Merger, etc.”) shall be read to apply to
the Collateral Agent and the Security Documents, mutatis mutandis, in addition to this Indenture; provided that the Collateral
Agent’s standard of care of gross negligence or willful misconduct shall not be affected or changed after the occurrence
and during the continuation of an Event of Default. The privileges, rights, indemnities, immunities and exculpatory provisions
contained in this Indenture, including the right to be indemnified, shall apply to the Collateral Agent, whether it is acting under
this Indenture or the Security Documents, and shall be enforceable by the Collateral Agent. Each Holder of Notes, by its acceptance
of the Notes (a) consents to the terms of the Note Documents, (b) agrees that it will be bound by, and will take no actions
contrary to, the provisions of the Note Documents and (c) authorizes and instructs the Collateral Agent, on behalf of each
Holder of Notes to enter into the Note Documents.

Section 7.13     Separate
Trustees and Co-Trustees

 

(a)     Notwithstanding
any other provisions hereof, at any time, for the purpose of meeting legal requirements applicable to it in the performance of
its duties hereunder, the Trustee shall have the power to, and shall execute and deliver all instruments to, appoint one or more
Persons to act as separate trustees or co-trustees hereunder of any portion of the Collateral subject to this Indenture, and any
such Persons shall be such separate trustee or co-trustee, with such powers and duties consistent with this Indenture as shall
be specified in the instrument appointing such Person. If the Trustee shall request the Company to do so, the Company shall join
with the Trustee in the execution of such instrument, but the Trustee shall have the power to make such appointment without making
such request. A separate trustee or co-trustee appointed pursuant to this Section 7.13 need not meet the eligibility requirements
of Section 7.10. No trustee hereunder shall be personally liable because of any act or omission of any other trustee hereunder
and any appointed separate or co-trustee hereunder shall not be deemed an agent of the appointing trustee.

 

(b)    Every
separate trustee and co-trustee shall, to the extent not prohibited by law, be subject to the following terms and conditions:

 

(i)            the
rights, powers, duties and obligations conferred or imposed upon such separate or co- trustee shall be conferred or imposed upon
and exercised or performed by the Trustee and such separate or co-trustee jointly, as shall be provided in the appointing instrument,
except to the extent that under any law of any jurisdiction in which any particular act is to be performed any nonresident trustee
shall be incompetent or unqualified to perform such act, in which event such rights, powers, duties and obligations shall be exercised
and performed by such separate trustee or co-trustee at the direction of the Trustee;

 

(ii)            all
powers, duties, obligations and rights conferred upon the Trustee, in respect of the custody of all cash deposited hereunder shall
be exercised solely by the Trustee; and

 

(iii)          the
Trustee may at any time by written instrument accept the resignation of or remove any such separate trustee or co-trustee, and,
upon the request of the Trustee, the Company shall join with the Trustee in the execution, delivery and performance of all instruments
and agreements necessary or proper to make effective such resignation or removal, but the Trustee shall have the power to accept
such resignation or to make such removal without making such request. A successor to a separate trustee or co-trustee so resigning
or removed may be appointed in the manner otherwise provided herein.

 

(c)     Such
separate trustee or co-trustee, upon acceptance of such trust, shall be vested with the estates or property specified in such instruments,
jointly with the Trustee, and the Trustee shall take such action as may be necessary to provide for (i) the appropriate interest
in the Collateral to be vested in such separate trustee or co- trustee and (ii) the execution and delivery of any transfer
documentation or bond powers that may be necessary to give effect to the transfer of the Lien hereof to the co-trustee. Any separate
trustee or co-trustee may, at any time, by written instrument constitute the Trustee, its agent or attorney-in-fact with full power
and authority, to the extent permitted by law, do all acts and things and exercise all discretion authorized or permitted by it,
for and on behalf of it and in its name. The Trustee shall not be responsible for any action or inaction of any separate trustee
or co-trustee. If any separate trustee or co-trustee shall be dissolved, become incapable of acting, resign, be removed or die,
all the estates, property, rights, powers, trusts, duties and obligations of said separate trustee or co-trustee, so far as permitted
by law, shall vest in and be exercised by the Trustee, without the appointment of a successor to said separate trustee or co-trustee,
until the appointment of a successor to said separate trustee or co-trustee is necessary as provided in this Indenture.

 

    98

     

    

 

(d)     Any
notice, request or other writing, by or on behalf of any Holder, delivered to the Trustee shall be deemed to have been delivered
to all separate trustees and co-trustees.

 

(e)    [Intentionally
Omitted.]

 

(f)     No
appointment of a separate trustee or co-trustee pursuant to this Section 7.13 shall relieve the Trustee of any of its obligations,
duties or responsibilities hereunder in any way or to any degree.

 

ARTICLE 8

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 Officers’ Certificate, elect
to have either Section 8.02 or 8.03 hereof be applied to all outstanding Notes upon compliance with the conditions set forth
below in this Article 8.

 

Section 8.02     Legal
Defeasance and Discharge.

 

Upon the Company’s
exercise under Section 8.01 hereof 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 hereof, be deemed to have been discharged from
their obligations with respect to all outstanding Notes (including the Note Guarantees) on the date the conditions set forth below
are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the 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
hereof and the other Sections of this Indenture referred to in clauses (i) and (ii) below, and to have satisfied all
their other obligations under such Notes, the Note Guarantees and this Indenture (and the Trustee, at the written request and sole
expense of the Company, shall execute proper instruments acknowledging the same), except for the following provisions which will
survive until otherwise terminated or discharged hereunder:

 

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

 

    99

     

    

 

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

 

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

 

(iv)          this
Article 8.

 

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

 

Section 8.03     Covenant
Defeasance.

 

Upon
the Company’s exercise under Section 8.01 hereof 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 hereof, 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, 4.19 and 4.20 hereof and clause (iv) of Section 5.01 hereof with respect to the outstanding Notes on and after
the date the conditions set forth in Section 8.04 hereof are satisfied (hereinafter, “Covenant Defeasance”),
and the Notes will thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration
or act of Holders (and the consequences of any thereof) in connection with such covenants, but will continue to be deemed “outstanding”
for all other purposes hereunder (it being understood that such Notes will not be deemed outstanding for accounting purposes).
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 hereof, but, except as specified above, the remainder of this
Indenture and such Notes and Note Guarantees will be unaffected thereby. In addition, upon the Company’s exercise under Section 8.01     hereof
of the option applicable to this Section 8.03, subject to the satisfaction of the conditions set forth in Section 8.04
hereof, Sections 6.01(iii), (iv), (v), (vi), (vii) and (x) hereof will not constitute Events of Default.

 

Section 8.04     Conditions
to Legal or Covenant Defeasance.

 

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

 

(i)            the
Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders of the Notes, cash in U.S. dollars,
non-callable Government Securities, or a combination thereof, 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, premium on, if
any, and interest 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;

 

    100

     

    

 

(ii)            in
the case of an election under Section 8.02 hereof, the Company must deliver to the Trustee and the Collateral Agent an Opinion
of Counsel 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 federal income tax law,

 

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

 

(iii)           in
the case of an election under Section 8.03 hereof, the Company must deliver to the Trustee an Opinion of Counsel confirming
that the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of
such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times
as would have been the case if such Covenant Defeasance had not occurred;

 

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

 

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

 

(vi)          the
Company must deliver to the Trustee an Officers’ 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

 

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

 

The Collateral will
be released from the Lien securing the Notes and the other Note Documents, as provided in Section 10.04 hereof, upon a Legal
Defeasance or Covenant Defeasance in accordance with the provisions described above.

 

    101

     

    

 

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

 

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

 

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 hereof or the principal and interest received in respect thereof other than
any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes.

 

Notwithstanding anything
in this Article 8 to the contrary, the Trustee will deliver or pay to the 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 hereof which, in the opinion
of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the
Trustee (which may be the opinion delivered under Section 8.04(i) hereof), are in excess of the amount thereof that would
then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

 

Section 8.06     Repayment
to 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 on, 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 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; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at
the expense of the Company cause to be published once, in the New York Times and The Wall Street Journal (national edition), notice
that such money remains unclaimed and that, after a date specified therein, which will not be less than 30 days from the date of
such notification or publication, any unclaimed balance of such money then remaining will be repaid to the Company.

 

    102

     

    

 

Section 8.07     Reinstatement.

 

If the Trustee or Paying
Agent is unable to apply any U.S. dollars or non-callable Government Securities in accordance with Section 8.02 or 8.03 hereof,
as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise
prohibiting such application, then the 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
hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.02
or 8.03 hereof, as the case may be; provided, however, that, if the Company makes any payment of principal of, premium on,
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.

Indenture (including, without limitation, Sections 3.09, 4.10, and 4.14 hereof), the Notes, the Note Guarantees or any other Note
Documents 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, subject to Sections 6.04 and 6.07 hereof, any existing
Default or Event of Default (other than a Default or Event of Default in the payment of the principal of, premium on, if any, or
interest on, the Notes, except a payment default resulting from an acceleration that has been rescinded) or compliance with any
provision of this Indenture or the Notes or the Note Guarantees may be waived with the consent of the Holders of a majority in
aggregate principal amount of the then outstanding Notes (including, without limitation, Additional Notes, if any) voting as a
single class (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase
of, the Notes). Section 2.08 hereof shall determine which Notes are considered to be “outstanding” for purposes
of this Section 9.02.

 

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

 

    104

     

    

 

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 becomes effective, the Company will mail to the Holders of Notes affected thereby
a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail 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 hereof, 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, the Notes
or the Note Guarantees. However, without the consent of each Holder affected, an amendment, supplement or waiver under this Section 9.02
may not (with respect to any Notes held by a non-consenting Holder):

 

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

 

(ii)           reduce
the principal of or change the fixed maturity of any Note or alter or waive any of the provisions with respect to the redemption
or repurchase of the Notes (except as provided above with respect to Sections 3.09, 4.10 and 4.14 hereof);

 

(iii)           reduce
the rate of or change the time for payment of interest, including default interest, on any Note;

 

(iv)          waive
a Default or Event of Default in the payment of principal of, premium on, if any, or interest 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);

 

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

 

(vi)           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, premium, if any, on, interest on the Notes (other than as permitted by clause (vii) below);

 

(vii)        waive
a redemption payment with respect to any Note (other than a payment required by Sections 3.09, 4.10 or 4.14 hereof);

 

    105

     

    

 

 

(viii)          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

 

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

 

In addition, any amendment
to, or waiver of, the provisions of this Indenture or any security document that has the effect of releasing all or substantially
all of the Collateral from the Liens securing the Notes or releasing all or substantially all of the Guarantors from their respective
Guarantees will require the consent of the Holders of at least 662/3% in aggregate principal amount of the Notes then
outstanding.

 

In determining with
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 any of their respective Subsidiaries, will be considered as though not outstanding, except that for the purposes
of determining whether the Trustee will be protecting in relying on any such direction, waiver, or consent, only Notes that a Responsible
Officer of the Trustee receives an Officers’ Certificate from the Company that such Notes are so owned will be so disregarded.
Upon request of the Trustee, the Company shall furnish to the Trustee promptly an Officers’ Certificate listing and identifying
all Notes, if any, known by the Company to be owned or held by or for the account of any of the above described Persons, and the
Trustee shall be entitled to accept and rely upon such Officers’ Certificate as conclusive evidence of the facts therein
set forth and of the fact that all Notes not listed therein are outstanding for the purpose of any such determination.

 

Section 9.03         Trust
Indenture Act.

 

Every amendment or
supplement to this Indenture or the Notes will be set forth in an amended or supplemental indenture that complies with the TIA
as then in effect.

 

Section 9.04         Revocation
and Effect of Consents.

 

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

 

Section 9.05         Notation
on or Exchange of Notes.

 

The Trustee may place
an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The 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.

 

    106

     

    

 

Section 9.06         Trustee
to Sign Amendments, etc.

 

The Trustee will sign
any amendment or supplemental indenture authorized pursuant to this Article 9 if the amendment or supplement does not adversely
affect the rights, duties, liabilities or immunities of the Trustee. The Company may not sign an amendment or supplemental indenture
until the Board of Directors of the Company approves it. In executing any amendment or supplemental indenture, the Trustee will
be entitled to receive and (subject to Section 7.01 hereof) will be fully protected in relying upon, in addition to the documents
required by Section 14.04 hereof, an Officers’ Certificate and an Opinion of Counsel stating that the execution of such
amendment or supplemental indenture is authorized or permitted by this Indenture and that such amendment, supplement or waiver
is the legal, valid and binding obligation of the Company and any Guarantors party thereto, enforceable against them in accordance
with its terms, subject to customary exceptions.

required by the provisions of the Security Documents, to assure and confirm to the Trustee and the Collateral Agent the security
interest in the Collateral contemplated hereby, by the Security Documents or any part thereof, as from time to time constituted,
so as to render the same available for the security and benefit of this Indenture and of the Notes secured hereby, according to
the intent and purposes herein expressed. The Company will take, and will cause its Subsidiaries to take any and all actions necessary
or proper or as may be reasonably requested by the Collateral Agent to cause the Security Documents to create and maintain, as
security for the Obligations of the Company hereunder, a valid and enforceable perfected second priority Lien in and on all the
Collateral, in favor of the Collateral Agent for the benefit of the Holders of Notes, superior to and prior to the rights of all
third Persons and subject to no other Liens other than Permitted Prior Liens.

Section 10.02        Recording

(a)          The
Company will furnish to the Collateral Agent and the Trustee on [●] in each year beginning with [●], an Opinion of

as is necessary to maintain the Lien of the Security Documents and reciting with respect to the security interests in the Collateral

that, in the opinion of such counsel, no such action is necessary to maintain such Lien and assignment.

 

(b)          The
Company will comply with the provisions of TIA § 314; provided that the Company will not be required to comply with all or
any portion of TIA §314(d) if it determines in good faith based on the advice of counsel, that under the terms of TIA
 §314(d) and/or any interpretation or guidance as to the meaning thereof of the SEC and its staff, including “no-action”
letters or exemptive orders (whether issued to the Company or any other person), all or any portion of TIA §314(d) is
inapplicable to the released Collateral.

 

Section 10.03       Release
of Liens on Collateral.

 

The Collateral Agent’s
Second Liens upon the Collateral will be released in any one or more of the circumstances set forth in the Intercreditor Agreement,
and in any such event, each of the Trustee and Collateral Agent shall release the Collateral upon request from Priority Lien Collateral
Agent or the Priority Lien Representative, and neither the Trustee nor Collateral Agent shall be liable for verifying whether such
release is authorized or permitted pursuant to the Indenture or any Note Document and each of the Trustee and the Collateral Agent
may conclusively rely on such request, and incur no liability for any releases effected pursuant to such request.

 

    108

     

    

 

Section 10.04       Release
of Liens in Respect of Notes.

 

(a)         The
Collateral Agent’s Second Liens upon the Collateral will no longer secure the Notes outstanding under this Indenture or any
other Obligations under this Indenture, and the right of the Holders of the Notes and such Obligations to the benefits and proceeds
of the Collateral Agent’s Second Liens on the Collateral shall terminate and be discharged:

shall have occurred and be continuing;

 

(vi)            as
provided in Intercreditor Agreement; or

 

(vii)          to
enable the disposition of assets that constitute Collateral to the extent not prohibited by Section 4.10.

 

(b)         Upon
the full and final payment and performance of all Obligations of the Company under this Indenture and the Notes or upon Legal Defeasance,
Covenant Defeasance or satisfaction and discharge of this Indenture in accordance with Article 12 hereof, the Company will
deliver a certificate to the Collateral Agent stating that such Obligations have been paid in full, and instruct the Collateral
Agent to release the Liens pursuant to this Indenture and the Security Documents.

 

Section 10.05       Certificates
of the Company.

 

The Company will furnish
to the Trustee and the Collateral Agent, prior to each proposed release of Collateral pursuant to the Security Documents:

 

(i)              all
documents required by TIA §314(d);

 

(ii)             an
Officers’ Certificate certifying that all conditions precedent under this Indenture and the Note Documents if any, to such
release have been met and any necessary or proper instruments of termination, satisfaction or release prepared by the Company;

The Trustee and the
Collateral Agent may accept as conclusive evidence of compliance with the foregoing provisions the appropriate statements contained
in such documents and such Opinion of Counsel. Neither the Trustee nor the Collateral Agent shall be liable for any such release
undertaken in good faith in reliance upon any such Officers’ Certificate or Opinion of Counsel, and notwithstanding any term
hereof or in any Note Document to the contrary, the Trustee and Collateral Agent shall not be under any obligation to release any
such Lien and security interest, or execute and deliver any such instrument of release, satisfaction or termination, unless and
until it receives such Officers’ Certificate and Opinion of Counsel.

 

    109

     

    

 

Section 10.06       Certificates
of the Trustee.

 

Neither the Trustee
nor the Collateral Agent shall have any duty to confirm the legality, sufficiency, genuineness, accuracy, contents or validity
of any documents (or any signature appearing therein). Neither the Trustee nor the Collateral Agent shall be liable for any such
release undertaken in good faith in reliance upon any documents delivered to them pursuant to Section 10.05 hereof, and notwithstanding
any term hereof or in any Note Document to the contrary, neither the Trustee nor the Collateral Agent shall be under any obligation
to release any such Lien and security interest, or execute and deliver any such instrument of release, satisfaction or termination,
unless and until it receives such documents.

 

Section 10.07        Authorization
of Actions to Be Taken Under the Security Documents.

 

Subject to the provisions
of Section 7.01 and 7.02 hereof and to the terms of the Intercreditor Agreement, the Trustee and the Collateral Agent may,
on behalf of the Holders of Notes, take all actions to:

 

(i)              enforce
any of the terms of the Security Documents; and

 

(ii)             collect
and receive any and all amounts payable in respect of the Obligations of the Company hereunder and under the Security Documents.

 

The Collateral Agent
will have power to institute and maintain such suits and proceedings as it may deem expedient to prevent any impairment of the
Collateral by any acts that may be unlawful or in violation of the Security Documents or this Indenture, and such suits and proceedings
to preserve or protect its interests and the interests of the Holders of Notes in the Collateral (including power to institute
and maintain suits or proceedings to restrain the enforcement of or compliance with any legislative or other governmental enactment,
rule or order that may be unconstitutional or otherwise invalid if the enforcement of, or compliance with, such enactment,
rule or order would impair the security interest hereunder or be prejudicial to the interests of the Holders of Notes, of
the Collateral Agent or of the Trustee). Nothing in this Section 10.07 shall be considered to impose any such duty or obligation
to act on the part of the Trustee or the Collateral Agent.

 

Notwithstanding the
foregoing, the Collateral Agent or the Trustee may, at the expense of the Company, request the direction of the Holders of Notes
with respect to any such actions and upon receipt of the written consent of Holders of at least a majority in aggregate principal
amount of the then outstanding Notes, shall take such actions; provided that all actions so taken shall, at all times, be in conformity
with the requirements of the Intercreditor Agreement.

 

Section 10.08        Authorization

of the Intercreditor Agreement, proceeds in respect of the Collateral received by the Collateral Agent shall be passed on to the

Documents, and to make further distributions of such funds to the Holders of Notes according to the provisions of this Indenture.

 

    110

     

    

 

Section 10.09        Collateral
Agent.

 

(a)           UMB
Bank, National Association, is hereby appointed as Collateral Agent and shall be authorized to appoint co-Collateral Agents as
necessary in its sole discretion. Each Holder agrees that any action taken by the Collateral Agent in accordance with the provisions
of this Indenture and the Security Documents, and the exercise by the Collateral Agent of any rights or remedies set forth herein
and therein shall be authorized and binding upon all Holders. Notwithstanding any provision to the contrary contained elsewhere
in this Indenture and the Security Documents, the duties of the Collateral Agent shall be ministerial and administrative in nature,
and the Collateral Agent shall not have any duties or responsibilities, except those expressly set forth herein and in the other
documents to which the Collateral Agent is a party, nor shall the Collateral Agent have or be deemed to have any trust or other
fiduciary relationship with the Trustee, any Holder, the Company or any Guarantor, and no implied covenants, functions, responsibilities,
duties, obligations or liabilities shall be read into this Indenture and the Security Documents or otherwise exist against the
Collateral Agent. Without limiting the generality of the foregoing sentence, the use of the term “agent” in this Indenture
with reference to the Collateral Agent is not intended to connote any fiduciary or other implied (or express) obligations arising
under agency doctrine of any applicable law. Instead, such term is used merely as a matter of market custom, and is intended to
create or reflect only an administrative relationship between independent contracting parties.

 

(b)          The
Collateral Agent makes no representations as to, and shall not be responsible for the existence, genuineness, value, sufficiency
or condition of any of the Collateral or as to the security afforded or intended to be afforded thereby, hereby or by any Security
Document, or for the validity, perfection, priority or enforceability of the Liens or security interests in any of the Collateral
created or intended to be created by any of the Security Documents, whether impaired by operation of law or by reason of any action
or omission to act on its part hereunder, for the validity or sufficiency of the Collateral, any Security Documents or any agreement
or assignment thereof contained in any provision thereof, for the validity of the title of the Company or any Guarantor to the
Collateral, for insuring the Collateral or for the payment of taxes, charges, assessments or Liens upon the Collateral or otherwise
as to the maintenance of the Collateral, all such responsibilities and obligations being responsibilities and obligations of the
Company and the Guarantors. The Collateral Agent shall not have any responsibility for recording, registering, filing, re-recording,
re-registering or refiling any supplemental indenture, financing statement, continuation statement, document, instrument or other
notice in any public office at any time or times or to otherwise take any action to perfect or maintain the perfection of any security
interest granted to it under the Security Documents or otherwise (except for the safe custody of any Collateral in its possession
and the accounting for moneys actually received by it hereunder or under any Security Document) and such responsibility shall be
solely that of the Company.

 

    111

     

    

 

(c)           The
Collateral Agent shall be entitled to rely, and shall be fully protected in relying, upon any writing, resolution, notice, consent,
certificate, affidavit, letter, telegram, facsimile, certification, telephone message, statement, or other communication, document
or conversation (including those by telephone or e- mail) believed by it to be genuine and correct and to have been signed, sent,
or made by the proper Person or Persons, and upon advice and statements of legal counsel (including, without limitation, counsel
to the Company or any Guarantor), independent accountants and other experts and advisors selected by the Collateral Agent. The
Collateral Agent shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate,
statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, or other paper or document.
The Collateral Agent shall in all cases be fully protected in acting, or in refraining from acting, under this Indenture or the
Security Documents in accordance with a request, direction, instruction or consent of the Company, the Trustee or the Holders of
a requisite percentage in aggregate principal amount of the then outstanding Notes.

 

This Article 10
and the provisions of each other Security Document are subject to the terms, conditions and benefits set forth in the Intercreditor
Agreement. The Company and each Guarantor consents to, and agrees to be bound by, the terms of the Intercreditor Agreement, as
the same may be in effect from time to time, and to perform its obligations thereunder in accordance with the terms thereof. Each
Holder of Notes, by its acceptance of the Notes (a) consents to the terms provided for in the Intercreditor Agreement, (b) agrees
that it will be bound by, and will take no actions contrary to, the provisions of the Intercreditor Agreement and (c) authorizes
and instructs the Trustee and the Collateral Agent, in each case, on behalf of each Holder of Notes to enter into the Intercreditor
Agreement as Second Lien Representative and as Second Lien Collateral Agent (as such terms are defined in the Intercreditor Agreement),
in each case, on behalf of such Holders of Notes. In addition, each Holder of Notes authorizes and instructs the Trustee and the
Collateral Agent to enter into any amendments or joinders to the Intercreditor Agreement, without the consent of any Holder, to
add additional Indebtedness as Second Lien Debt and add other parties (or any authorized agent or trustee therefor) holding such
Indebtedness thereto and to establish that the Lien on any Collateral securing such Indebtedness ranks equally with the Liens on
such Collateral securing the other Second Lien Debt then outstanding. The foregoing provisions are intended as an inducement to
the lenders under the Credit Agreement to extend credit to the Company and certain of its Subsidiaries, and such lenders are intended
third party beneficiaries of such provisions and the provisions of the Intercreditor Agreement.

 

ARTICLE 11

NOTE GUARANTEES

 

Section 11.01        Guarantee.

 

(a)           Subject
to this Article 11, each of the Guarantors hereby, jointly and severally, unconditionally guarantees to each Holder of a Note
authenticated and delivered by the Trustee and to the Trustee and the Collateral Agent and their respective successors and assigns,
irrespective of the validity and enforceability of this Indenture, the Notes, the Security Documents or the obligations of the
Company hereunder or thereunder, that:

 

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

 

    112

     

    

 

(ii)             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. 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 covenant
that this Note Guarantee will not be discharged except by complete performance of the obligations contained in the Notes and this
Indenture.

 

(c)           If
any Holder, the Collateral Agent 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, the Collateral Agent 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, the Collateral Agent and the Trustee, on the other hand, (1) the maturity of
the obligations guaranteed hereby may be accelerated as provided in Article 6 hereof for the purposes of this Note Guarantee,
notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed
hereby, and (2) in the event of any declaration of acceleration of such obligations as provided in Article 6 hereof,
such obligations (whether or not due and payable) will forthwith become due and payable by the Guarantors for the purpose of this
Note Guarantee. The Guarantors will have the right to seek contribution from any non-paying Guarantor so long as the exercise of
such right does not impair the rights of the Holders under the Note Guarantee.

 

    113

     

    

 

Section 11.02        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 11, result in the obligations of such Guarantor under its Note Guarantee not constituting a fraudulent
transfer or conveyance.

 

Section 11.03        Execution
and Delivery of Note Guarantee.

 

To evidence its Note
Guarantee set forth in Section 11.01 hereof, each Guarantor hereby agrees that a notation of such Note Guarantee substantially
in the form attached as Exhibit E hereto will be endorsed by an Officer of such Guarantor on each Note authenticated and delivered
by the Trustee and that this Indenture will be executed on behalf of such Guarantor by one of its Officers.

 

Each Guarantor hereby
agrees that its Note Guarantee set forth in Section 11.01 hereof will remain in full force and effect notwithstanding any
failure to endorse on each Note a notation of such Note Guarantee.

 

If an Officer whose
signature is on 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 4.15 hereof, the Company will cause such Domestic Subsidiary to comply with the provisions of Section 4.15
hereof and this Article 11, to the extent applicable.

 

Section 11.04        Guarantors
May Consolidate, etc., on Certain Terms.

 

Except as otherwise
provided in Section 11.05 hereof, no Guarantor may sell or otherwise dispose of all or substantially all of its assets to,
or consolidate with or merge with or into (whether or not such Guarantor is the surviving Person) another Person, other than the
Company or another Guarantor, unless:

 

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

 

and

 

(ii)             either:

 

    114

     

    

 

(A)            subject
to Section 11.05 hereof, the Person acquiring the property in any such sale or disposition or the Person formed by or surviving
any such consolidation or merger unconditionally assumes all the obligations of that Guarantor under its Note Guarantee, this Indenture
and the Security Documents on the terms set forth herein or therein, pursuant to a supplemental indenture and appropriate security
documents in form and substance reasonably satisfactory to the Trustee; or

 

(B)             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 hereof.

 

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

 

Except as set forth
in Articles 4 and 5 hereof, and notwithstanding clauses (ii)(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 11.05        Releases.

 

(a)          The
Note Guarantee of a Guarantor will automatically be released:

 

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

 

(ii)           in
connection with any sale or other disposition of Capital Stock of that Guarantor by way of merger, consolidation or otherwise to
a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary of the Company,
if the sale or other disposition does not violate the provisions described in Section 4.10 hereof and the Guarantor ceases
to be a Restricted Subsidiary of the Company as a result of the sale or other disposition;

 

    115

     

    

 

(iii)          if
the Company designates any Restricted Subsidiary that is a Guarantor to be an Unrestricted Subsidiary in accordance with the applicable
provisions of this Indenture;

 

(iv)         upon
legal defeasance, covenant defeasance or satisfaction and discharge of this Indenture as provided in Articles 8 and 12 hereof;

 

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

 

(b)          if
consent to such release has been given by an Act of Supermajority Debtholders.

 

(c)          Any
Guarantor not released from its obligations under its Note Guarantee as provided in this Section 11.05 will remain liable
for the full amount of principal of, premium on, if any, and interest on, the Notes and for the other obligations of any Guarantor
under this Indenture as provided in this Article 11.

 

ARTICLE 12

SATISFACTION AND DISCHARGE

 

Section 12.01        Satisfaction
and Discharge.

 

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

 

(i)            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 mailing 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,
non-callable Government Securities, or a combination thereof, in such 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 interest to the date of maturity or redemption;

 

(ii)            in
respect of subclause (B) of clause (i) of this Section 12.01, no Default or Event of Default has occurred and is
continuing on the date of the deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied
to such deposit and any similar deposit relating to other Indebtedness and, in each case, the granting of Liens to secure such
borrowings) and the deposit will not result in a breach or violation of, or constitute a default under, any other instrument to
which the Company or any Guarantor is a party or by which the Company or any Guarantor is bound (other than with respect to the
borrowing of funds to be applied concurrently to make the deposit required to effect such satisfaction and discharge and any similar
concurrent deposit relating to other Indebtedness, and in each case the granting of Liens to secure such borrowings);

 

    116

     

    

 

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

 

(iv)          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
Officers’ Certificate and an Opinion of Counsel to the Trustee stating that all conditions precedent to satisfaction and
discharge have been satisfied.

 

The Collateral will
be released from the Lien securing the Notes and the other Note Documents, as provided in Section 10.04 hereof, upon a satisfaction
and discharge in accordance with the provisions described above. Nothing in this Section 12.01 will be deemed to preclude
the Company from repurchasing Notes, including, but not limited to, in the open market, through a tender offer or exchange offer,
through privately negotiated transactions, or other similar transactions.

 

Notwithstanding the
satisfaction and discharge of this Indenture, if money has been deposited with the Trustee pursuant to subclause (B) of clause
(i) of this Section 12.01, the provisions of Sections 12.02 and 8.06 hereof will survive. In addition, nothing in this
Section 12.01 will be deemed to discharge those provisions of Section 7.07 hereof, that, by their terms, survive the
satisfaction and discharge of this Indenture.

 

Section 12.02        Application
of Trust Money.

 

Subject to the provisions
of Section 8.06 hereof, all money deposited with the Trustee pursuant to Section 12.01 hereof shall be held in trust
and applied by it, in accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through
any Paying Agent (including the Company acting as its own Paying Agent), to the Persons entitled thereto, of the principal, premium,
if any, and interest for whose payment such money has been deposited with the Trustee; but such money need not be segregated from
other funds except to the extent required by law.

 

If the Trustee or Paying
Agent is unable to apply any money or Government Securities in accordance with Section 12.01 hereof by reason of any legal
proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting
such application, the 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 12.01 hereof; provided that if the Company has
made any payment of principal of, premium on, 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.

ARTICLE 13

CONVERSION OF NOTES

 

Section 13.01        Conversion
Privilege.

 

Subject to and upon
compliance with the provisions of this Article 13 (including, for the avoidance of doubt, the restrictions set forth in Section 13.12),
each Holder of a Note shall have the right, at such Holder’s option, to convert all or any portion (if the portion to be
converted is $1,000 principal amount or an integral multiple thereof) of such Note at any time prior to the close of business on
the Business Day immediately preceding the Maturity Date at an initial conversion rate of 333.3333 shares of Common Stock (subject
to adjustment as provided in this Article 13) (the “Conversion Rate”) per $1,000 principal amount of Notes (subject
to, and in accordance with, the settlement provisions of Section 13.02, the “Conversion Obligation”). With respect
to any Notes that are converted after the date of issuance of a Redemption Notice (other than in connection with an Acquisition
Redemption) and prior to the close of business on the Scheduled Trading Day immediately preceding the related Redemption Date (unless
the Company fails to pay the redemption price as required under Section 3.07 (in which case a Holder may convert such Note
until the redemption price, including the Applicable Premium (if any), has been paid or duly provided for), in addition to the
payment or delivery of the consideration due upon conversion as described in Section 13.02, the Company shall pay or deliver,
as the case may be, the Make-Whole Premium in cash, shares of Common Stock or a combination of cash and shares of Common Stock,
as specified in the Redemption Notice and described in Section 3.07.

 

Section 13.02        Conversion
Procedure.

 

(a) Subject to
this Section 13.02, Section 13.03(b), Section 13.07(a) and Section 13.12, upon conversion of any Note,
the Company shall pay or deliver, as the case may be, to the converting Holder, in respect of each $1,000 principal amount of Notes
being converted, cash (“Cash Settlement”), shares of Common Stock, together with cash, if applicable, in lieu of delivering
any fractional share of Common Stock in accordance with subsection (j) of this Section 13.02 (“Physical Settlement”)
or a combination of cash and shares of Common Stock, together with cash, if applicable, in lieu of delivering any fractional share
of Common Stock in accordance with subsection (j) of this Section 13.02 (“Combination Settlement”), at its
election, as set forth in this Section 13.02. Notwithstanding the foregoing, to the extent the Board of Directors determines
in good faith that the issuance of any shares of Common Stock upon any conversion of the Notes or in respect of any Make-Whole
Premium could cause the Company to undergo an “ownership change” as defined in Section 382 of the Internal Revenue
Code of 1986, as amended, and the Treasury Regulations promulgated thereunder or otherwise could materially and adversely affect
the Company’s ability to preserve its ability to utilize its net operating loss carryforwards for U.S. federal income tax
purposes, the Company may elect to settle such conversion through Cash Settlement or Combination Settlement and to settle such
Make-Whole Premium in cash or in a combination of cash and shares of Common Stock, in each case, to the extent of such determination.

 

    118

     

    

 

(i) All
conversions for which the relevant Conversion Date occurs on or after September 15, 2025, and all conversions for which the
relevant Conversion Date occurs after the Company’s issuance of a Redemption Notice with respect to the Notes and prior to
the related Redemption Date, shall be settled using the same Settlement Method.

 

(ii) Except
for any conversions for which the relevant Conversion Date occurs after the Company’s issuance of a Redemption Notice with
respect to the Notes but prior to the related Redemption Date, any conversions for which the relevant Conversion Date occurs on
or after September 15, 2025, the Company shall use the same Settlement Method for all conversions with the same Conversion
Date, but the Company shall not have any obligation to use the same Settlement Method with respect to conversions with different
Conversion Dates.

 

(iii) If,
in respect of any Conversion Date (or one of the periods described in the third immediately succeeding set of parentheses, as the
case may be), the Company elects a Settlement Method in respect of such Conversion Date (or such period, as the case may be), the
Company shall deliver or cause delivery of a notice (the “Settlement Notice”) of the relevant Settlement Method to
converting Holders and the Conversion Agent (and the Trustee if not the Conversion Agent) no later than the close of business on
the Trading Day immediately following the relevant Conversion Date (or, in the case of any conversions for which the relevant Conversion
Date occurs (x) after the date of issuance of a Redemption Notice with respect to the Notes and prior to the related Redemption
Date, in such Redemption Notice or (y) on or after September 15, 2025, no later than September 15, 2025). Such
Settlement Notice shall specify the relevant Settlement Method and in the case of an election of Combination Settlement, the relevant
Settlement Notice shall indicate the Specified Dollar Amount per $1,000 principal amount of Notes. If the Company does not
elect a Settlement Method prior to the deadline set forth in the immediately preceding sentence, the Company shall no longer have
the right to elect Cash Settlement or Physical Settlement and the Company shall be deemed to have elected Combination Settlement
in respect of its Conversion Obligation, and the Specified Dollar Amount per $1,000 principal amount of Notes shall be equal to
$1,000.

 

If
the Company delivers a Settlement Notice electing Combination Settlement in respect of its Conversion Obligation but does not indicate
a Specified Dollar Amount per $1,000 principal amount of Notes in such Settlement Notice, the Specified Dollar Amount per $1,000
principal amount of Notes shall be deemed to be $1,000. For the avoidance of doubt, this clause (iii) and the provisions
hereof are subject to the provisions of Section 13.12.

 

(iv) The cash, shares of
Common Stock or combination of cash and shares of Common Stock in respect of any conversion of Notes (the “Settlement Amount”)
shall be computed by the Company as follows:

 

(A) if the Company elects
to satisfy its Conversion Obligation in respect of such conversion by Physical Settlement, the Company shall deliver to the converting
Holder in respect of each $1,000 principal amount of Notes being converted a number of shares of Common Stock equal to the Conversion
Rate in effect on the Conversion Date (plus cash in lieu of any fractional share of Common Stock issuable upon conversion in accordance
with Section 13.02(j);

 

    119

     

    

 

(B) if the Company elects
to satisfy its Conversion Obligation in respect of such conversion by Cash Settlement, the Company shall pay to the converting
Holder in respect of each $1,000 principal amount of Notes being converted cash in an amount equal to the sum of the Daily Conversion
Values for each of the 30 consecutive Trading Days during the related Observation Period; and

 

(C) if the Company elects
(or is deemed to have elected) to satisfy its Conversion Obligation in respect of such conversion by Combination Settlement, the
Company shall pay or deliver, as the case may be, to the converting Holder in respect of each $1,000 principal amount of Notes
being converted, a Settlement Amount equal to the sum of the Daily Settlement Amounts for each of the 30 consecutive Trading Days
during the related Observation Period (plus cash in lieu of any fractional share of Common Stock issuable upon conversion in accordance
with Section 13.02(j)).

 

(v) The Daily Settlement
Amounts (if applicable) and the Daily Conversion Values (if applicable) shall be determined by the Company promptly following the
last day of the Observation Period. Promptly after such determination of the Daily Settlement Amounts or the Daily Conversion Values,
as the case may be, and the amount of cash payable in lieu of delivering any fractional share of Common Stock, the Company shall
notify the Trustee and the Conversion Agent (if other than the Trustee) in writing of the Daily Settlement Amounts or the Daily
Conversion Values, as the case may be, and the amount of cash payable in lieu of delivering fractional shares of Common Stock.
The Trustee and the Conversion Agent (if other than the Trustee) shall have no responsibility for any such determination.

 

(b) Subject
to Section 13.02(e), before any Holder of a Note shall be entitled to convert a Note as set forth above, such Holder shall
(i) in the case of a Global Note, comply with the procedures of the Depositary in effect at that time and, if required, pay
funds equal to interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in Section 13.02(h) and
(ii) in the case of a Physical Note (1) complete, manually sign and deliver an irrevocable notice to the Conversion Agent
as set forth in the Form of Notice of Conversion (or a facsimile thereof) (a “Notice of Conversion”) at the office
of the Conversion Agent and state in writing therein the principal amount of Notes to be converted and the name or names (with
addresses) in which such Holder wishes the certificate or certificates for any shares of Common Stock to be delivered upon settlement
of the Conversion Obligation to be registered, (2) surrender such Notes, duly endorsed to the Company or in blank (and accompanied
by appropriate endorsement and transfer documents), at the office of the Conversion Agent, (3) if required, furnish appropriate
endorsements and transfer documents and (4) if required, pay funds equal to interest payable on the next Interest Payment
Date to which such Holder is not entitled as set forth in Section 13.02(h). The Trustee (and if different, the Conversion
Agent) shall notify the Company of any conversion pursuant to this Article 13 on the Conversion Date for such conversion.
No Notice of Conversion with respect to any Notes may be surrendered by a Holder thereof if such Holder has also delivered a Fundamental
Change repurchase notice to the Company in respect of such Notes and has not validly withdrawn such Fundamental Change repurchase
notice in accordance with Section 15.03.

 

If
more than one Note shall be surrendered for conversion at one time by the same Holder, the Conversion Obligation (including any
Make-Whole Premium) with respect to such Notes shall be computed on the basis of the aggregate principal amount of the Notes (or
specified portions thereof to the extent permitted thereby) so surrendered.

 

    120

     

    

 

(c) A
Note shall be deemed to have been converted immediately prior to the close of business on the date (the “Conversion Date”)
that the Holder has complied with the requirements set forth in subsection (b) above. Except as set forth in Section 13.03(b) and
Section 13.07(a), the Company shall pay or deliver, as the case may be, the consideration due in respect of the Conversion
Obligation (including any Make-Whole Premium) on the third Business Day immediately following the relevant Conversion Date, if
the Company elects Physical Settlement, or on the third Business Day immediately following the last Trading Day of the Observation
Period, in the case of any other Settlement Method. If any shares of Common Stock are due to converting Holders or in respect of
any Make-Whole Premium, the Company shall issue or cause to be issued, and deliver to the Conversion Agent or to such Holder, or
such Holder’s nominee or nominees, certificates or a book-entry transfer through the Depositary for the full number of shares
of Common Stock to which such Holder shall be entitled in satisfaction of the Company’s Conversion Obligation.

 

(d) In
case any Note shall be surrendered for partial conversion, the Company shall execute and the Trustee shall authenticate and deliver
to or upon the written order of the Holder of the Note so surrendered a new Note or Notes in authorized denominations in an aggregate
principal amount equal to the unconverted portion of the surrendered Note, without payment of any service charge by the converting
Holder but, if required by the Company or Trustee, with payment of a sum sufficient to cover any documentary, stamp or similar
issue or transfer tax or similar governmental charge required by law or that may be imposed in connection therewith as a result
of the name of the Holder of the new Notes issued upon such conversion being different from the name of the Holder of the old Notes
surrendered for such conversion.

 

(e) If
a Holder submits a Note for conversion or is entitled to receive any shares of Common Stock in respect of any Make-Whole Premium,
the Company shall pay any documentary, stamp or similar issue or transfer tax due on the issue of any shares of Common Stock upon
conversion or in respect of such Make-Whole Premium, unless the tax is due because the Holder requests such shares to be issued
in a name other than the Holder’s name, in which case the Holder shall pay that tax. The Conversion Agent may refuse to deliver
the certificates representing the shares of Common Stock being issued in a name other than the Holder’s name until the Trustee
receives a sum sufficient to pay any tax that is due by such Holder in accordance with the immediately preceding sentence.

 

(f) Except
as provided in Section 13.04, no adjustment shall be made for dividends on any shares of Common Stock issued upon the conversion
of any Note as provided in this Article 13.

 

(g) Upon
the conversion of an interest in a Global Note, the Trustee, or the Custodian at the direction of the Trustee, shall make a notation
on such Global Note as to the reduction in the principal amount represented thereby. The Company shall notify the Trustee in writing
of any conversion of Notes effected through any Conversion Agent other than the Trustee.

 

    121

     

    

 

(h) Upon
conversion, a Holder shall not receive any separate cash payment for accrued and unpaid interest, if any, except as set forth below
and other than any Make-Whole Premium, if applicable. The Company’s settlement of the full Conversion Obligation shall be
deemed to satisfy in full its obligation to pay the principal amount of the Note and accrued and unpaid interest, if any, to, but
not including, the relevant Conversion Date. As a result, accrued and unpaid interest, if any, to, but not including, the relevant
Conversion Date shall be deemed to be paid in full rather than cancelled, extinguished or forfeited. Upon a conversion of Notes
into a combination of cash and shares of Common Stock, accrued and unpaid interest will be deemed to be paid first out of the cash
paid upon such conversion. Notwithstanding the foregoing, if Notes are converted after the close of business on a Regular Record
Date, Holders of such Notes as of the close of business on such Regular Record Date will receive the full amount of interest payable
on such Notes on the corresponding Interest Payment Date notwithstanding the conversion. Notes surrendered for conversion during
the period from the close of business on any Regular Record Date to the open of business on the immediately following Interest
Payment Date must be accompanied by funds equal to the amount of interest payable on the Notes so converted; provided that
no such payment shall be required (1) for conversions following the Regular Record Date immediately preceding the Maturity
Date; (2) if the Company has specified a Redemption Date that is after a Regular Record Date and on or prior to the Business
Day immediately following the corresponding Interest Payment Date; (3) if the Company has specified a Fundamental Change Repurchase
Date that is after a Regular Record Date and on or prior to the Business Day immediately following the corresponding Interest Payment
Date; or (4) to the extent of any defaulted amounts, if any defaulted amounts exists at the time of conversion with respect
to such Note. Therefore, for the avoidance of doubt, all Holders of record on the Regular Record Date immediately preceding
the Maturity Date or any Redemption Date shall receive the full interest payment due on the Maturity Date or such Redemption Date,
as applicable, regardless of whether their Notes have been converted following such Regular Record Date.

 

(i) The
Person in whose name the shares of Common Stock shall be issuable upon conversion shall be treated as a stockholder of record as
of the close of business on the relevant Conversion Date (if the Company elects to satisfy the related Conversion Obligation by
Physical Settlement) or the last Trading Day of the relevant Observation Period (if the Company elects to satisfy the related Conversion
Obligation by Combination Settlement), as the case may be. Upon a conversion of Notes, such Person shall no longer be a Holder
of such Notes surrendered for conversion.

 

(j) The Company
shall not issue any fractional share of Common Stock upon conversion of the Notes and shall instead pay cash in lieu of delivering
any fractional share of Common Stock issuable upon conversion based on the Daily VWAP for the relevant Conversion Date (in the
case of Physical Settlement) or based on the Daily VWAP for the last Trading Day of the relevant Observation Period (in the case
of Combination Settlement). For each Note surrendered for conversion, if the Company has elected Combination Settlement, the full
number of shares that shall be issued upon conversion thereof shall be computed on the basis of the aggregate Daily Settlement
Amounts for the relevant Observation Period and any fractional shares remaining after such computation shall be paid in cash.

 

Section 13.03        Increased
Conversion Rate Applicable to Certain Notes Surrendered in Connection with Make-Whole Fundamental Change.

 

    122

     

    

 

(a)           If
the Effective Date of a Make-Whole Fundamental Change occurs prior to the Maturity Date and a Holder elects to convert its Notes
in connection with such Make-Whole Fundamental Change, the Company shall, under the circumstances described below, increase the
Conversion Rate for the Notes so surrendered for conversion by a number of additional shares of Common Stock (the “Additional
Shares”), as described below. A conversion of Notes shall be deemed for these purposes to be “in connection with”
such Make-Whole Fundamental Change if the relevant Notice of Conversion is received by the Conversion Agent from, and including,
the Effective Date of the Make-Whole Fundamental Change up to, and including, the Business Day immediately prior to the related
Fundamental Change Repurchase Date (or, in the case of a Make-Whole Fundamental Change that would have been a Fundamental Change
but for the proviso in clause (b) of the definition thereof, the 35th Trading Day immediately following the
Effective Date of such Make-Whole Fundamental Change).

 

(b)          Upon
surrender of Notes for conversion in connection with a Make-Whole Fundamental Change, the Company shall, at its option, satisfy
the related Conversion Obligation by Physical Settlement, Cash Settlement or Combination Settlement in accordance with Section 13.02
based on the Conversion Rate as increased to reflect the Additional Shares pursuant to the table set forth in Section 13.03(e) below;
provided, however, that if, at the effective time of a Make-Whole Fundamental Change described in clause (b) of the definition
of Fundamental Change, the Reference Property following such Make-Whole Fundamental Change is composed entirely of cash, for any
conversion of Notes following the Effective Date of such Make-Whole Fundamental Change, the Conversion Obligation shall be calculated
based solely on the Stock Price for the transaction and shall be deemed to be an amount of cash per $1,000 principal amount of
converted Notes equal to the Conversion Rate (including any adjustment for Additional Shares), multiplied by such Stock Price.
In such event, the Conversion Obligation shall be paid to Holders in cash on the third Business Day following the Conversion Date.
The Company shall notify the Holders of Notes, the Trustee and the Conversion Agent (if other than the Trustee) of the Effective
Date of any Make-Whole Fundamental Change and issue a press release announcing such Effective Date no later than five Business
Days after such Effective Date.

 

(c)          The
number of Additional Shares, if any, by which the Conversion Rate shall be increased shall be determined by reference to the table
set forth in Section 13.03(e) below, based on the date on which the Make-Whole Fundamental Change occurs or becomes effective
(the “Effective Date”) and the price (the “Stock Price”) paid (or deemed to be paid) per share of the Common
Stock in the Make-Whole Fundamental Change. If the holders of the Common Stock receive in exchange for their Common Stock only
cash in a Make-Whole Fundamental Change described in clause (b) of the definition of Fundamental Change, the Stock Price shall
be the cash amount paid per share. Otherwise, the Stock Price shall be the average of the Last Reported Sale Prices of the
Common Stock over the five Trading Day period ending on, and including, the Trading Day immediately preceding the Effective Date
of the Make-Whole Fundamental Change. The Board of Directors shall make appropriate adjustments to the Stock Price, in its
good faith determination, to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an
adjustment to the Conversion Rate where the Ex-Dividend Date, Effective Date (as such term is used in Section 13.04) or expiration
date of the event occurs during such five consecutive Trading Day period.

 

    123

     

    

 

(d)          The
Stock Prices set forth in the column headings of the table set forth in Section 13.03(e) below shall be adjusted as of
any date on which the Conversion Rate of the Notes is otherwise adjusted. The adjusted Stock Prices shall equal the Stock Prices
applicable immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the Conversion
Rate immediately prior to such adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion
Rate as so adjusted. The number of Additional Shares set forth in the table set forth in Section 13.03(e) below
shall be adjusted in the same manner and at the same time as the Conversion Rate as set forth in Section 13.04.

 

(e)           The
following table sets forth the number of Additional Shares of Common Stock by which the Conversion Rate shall be increased per

The
exact Stock Prices and Effective Dates may not be set forth in the table above, in which case:

 

(i) if
the Stock Price is between two Stock Prices in the table above or the Effective Date is between two Effective Dates in such table,
the number of Additional Shares shall be determined by a straight-line interpolation between the number of Additional Shares set
forth for the higher and lower Stock Prices and the earlier and later Effective Dates, as applicable, based on a 365-day year;

 

(ii) if
the Stock Price is greater than $[●] per share (subject to adjustment in the same manner as the Stock Prices set forth in
the column headings of the table above pursuant to subsection (d) above), no Additional Shares shall be added to the Conversion
Rate; and

 

(iii) if
the Stock Price is less than $[●] per share (subject to adjustment in the same manner as the Stock Prices set forth in the
column headings of the table above pursuant to subsection (d) above), no Additional Shares shall be added to the Conversion
Rate.

 

Notwithstanding
the foregoing, in no event shall the Conversion Rate per $1,000 principal amount of Notes exceed [●] shares of Common Stock,
subject to adjustment in the same manner as the Conversion Rate pursuant to Section 13.04.

 

(f)            Nothing in
this Section 13.03 shall prevent an adjustment to the Conversion Rate pursuant to Section 13.04 in respect of a Make-Whole
Fundamental Change

 

Section 13.04        Adjustment
of Conversion Rate.

 

The Conversion Rate
shall be adjusted from time to time by the Company if any of the following events occurs, except that the Company shall not make
any adjustments to the Conversion Rate if Holders of the Notes participate (other than in the case of (x) a share split or
share combination or (y) a tender or exchange offer), at the same time and upon the same terms as holders of the Common Stock
and solely as a result of holding the Notes, in any of the transactions described in this Section 13.04, without having to
convert their Notes, as if they held a number of shares of Common Stock equal to the Conversion Rate, multiplied by the
principal amount (expressed in thousands) of Notes held by such Holder.

 

    124

     

    

 

(a) If the
Company exclusively issues shares of Common Stock as a dividend or distribution on shares of the Common Stock, or if the Company
effects a share split or share combination, the Conversion Rate shall be adjusted based on the following formula:

 

 

 

where,

 

	CR0	=	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date of such dividend or distribution, or immediately prior to the open of business on the effective date of such share split or share combination, as applicable;
	 	 	 
	CR’	=	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date or effective date;
	 	 	 
	OS0	=	the number of shares of Common Stock outstanding immediately prior to the open of business on such Ex-Dividend Date or effective date; and
	 	 	 
	OS’	=	the number of shares of Common Stock outstanding immediately after giving effect to such dividend, distribution, share split or share combination.

 

Any adjustment
made under this Section 13.04(a) shall become effective immediately after the open of business on the Ex-Dividend Date
for such dividend or distribution, or immediately after the open of business on the Effective Date for such share split or share
combination, as applicable. If any dividend or distribution of the type described in this Section 13.04(a) is declared
but not so paid or made, the Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors or
a committee thereof determines not to pay such dividend or distribution, to the Conversion Rate that would then be in effect if
such dividend or distribution had not been declared.

 

(b) If,
other than with respect to the Rights Offering, if any, the Company issues to all or substantially all holders of the Common Stock
any rights, options or warrants entitling them, for a period of not more than 60 calendar days after the announcement date of such
issuance, to subscribe for or purchase shares of the Common Stock at a price per share that is less than the average of the Last
Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately
preceding the date of announcement of such issuance, the Conversion Rate shall be increased based on the following formula:

 

 

 

    125

     

    

 

 

where,

 

	CR0	=	 	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such issuance;
	CR’	=	 	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date;
	OS0	=	 	the number of shares of Common Stock outstanding immediately prior to the open of business on such Ex-Dividend Date;
	X	=	 	the total number of shares of Common Stock issuable pursuant to such rights, options or warrants; and
	Y	=	 	the number of shares of Common Stock equal to the aggregate price payable to exercise such rights, options or warrants, divided by the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of the issuance of such rights, options or warrants.

 

Any increase made
under this Section 13.04(b) shall be made successively whenever any such rights, options or warrants are issued and shall
become effective immediately after the open of business on the Ex-Dividend Date for such issuance. To the extent that shares
of the Common Stock are not delivered after the expiration of such rights, options or warrants, the Conversion Rate shall be decreased
to the Conversion Rate that would then be in effect had the increase with respect to the issuance of such rights, options or warrants
been made on the basis of delivery of only the number of shares of Common Stock actually delivered. If such rights, options
or warrants are not so issued, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect if such
Ex-Dividend Date for such issuance had not occurred.

 

For
purposes of this Section 13.04(b), in determining whether any rights, options or warrants entitle the holders to subscribe
for or purchase shares of the Common Stock at less than such average of the Last Reported Sale Prices of the Common Stock for the
10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement for
such issuance, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account
any consideration received by the Company for such rights, options or warrants and any amount payable on exercise or conversion
thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors or a committee thereof.

 

(c) If,
other than with respect to the Rights Offering, if any, the Company distributes shares of its Capital Stock, evidences of its indebtedness,
other assets or property of the Company or rights, options or warrants to acquire its Capital Stock or other securities, to all
or substantially all holders of the Common Stock, excluding (i) dividends, distributions or issuances as to which an adjustment
was effected pursuant to Section 13.04(a) or Section 13.04(b), (ii) dividends or distributions paid exclusively
in cash as to which the provisions set forth in Section 13.04(d) shall apply, and (iii) Spin-Offs as to which the
provisions set forth below in this Section 13.04(c) shall apply (any of such shares of Capital Stock, evidences of indebtedness,
other assets or property or rights, options or warrants to acquire Capital Stock or other securities, the “Distributed Property”),
then the Conversion Rate shall be increased based on the following formula:

 

 

 

    126

     

    

 

where,

 

	CR0	=	 	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such distribution;
	CR’	=	 	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date;
	SP0	=	 	the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such distribution; and
	FMV	=	 	the fair market value (as determined by the Board of Directors or a committee thereof) of the Distributed Property with respect to each outstanding share of the Common Stock on the Ex-Dividend Date for such distribution.

 

Any increase made under the portion
of this Section 13.04(c) above shall become effective immediately after the open of business on the Ex-Dividend Date
for such distribution. If such distribution is not so paid or made, the Conversion Rate shall be decreased to the Conversion Rate
that would then be in effect if such distribution had not been declared. Notwithstanding the foregoing, if “FMV” (as
defined above) is equal to or greater than “SP0” (as defined above), in lieu of the foregoing increase,
each Holder of a Note shall receive, in respect of each $1,000 principal amount thereof, at the same time and upon the same terms
as holders of the Common Stock receive the Distributed Property, the amount and kind of Distributed Property such Holder would
have received if such Holder owned a number of shares of Common Stock equal to the Conversion Rate in effect on the Ex-Dividend
Date for the distribution. If the Board of Directors determines the “FMV” (as defined above) of any distribution for
purposes of this Section 13.04(c) by reference to the actual or when-issued trading market for any securities, it shall
in doing so consider the prices in such market over the same period used in computing the Last Reported Sale Prices of the Common
Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend
Date for such distribution.

 

With respect to
an adjustment pursuant to this Section 13.04(c) where there has been a payment of a dividend or other distribution on
the Common Stock of shares of Capital Stock of any class or series, or similar equity interest, of or relating to a Subsidiary
or other business unit of the Company, that are, or, when issued, will be, listed or admitted for trading on a U.S. national securities
exchange (a “Spin-Off”), the Conversion Rate shall be increased based on the following formula:

 

 

    127

     

    

 

where,

 

	CR0	=	 	the Conversion Rate in effect immediately prior to the end of the Valuation Period;
	CR’	=	 	the Conversion Rate in effect immediately after the end of the Valuation Period;
	FMV0	=	 	the average of the Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to holders of the Common Stock applicable to one share of the Common Stock (determined by reference to the definition of Last Reported Sale Price as set forth in Section 1.01 as if references therein to Common Stock were to such Capital Stock or similar equity interest) over the first 10 consecutive Trading Day period after, and including, the Ex-Dividend Date of the Spin-Off (the “Valuation Period”); and
	MP0	=	 	the average of the Last Reported Sale Prices of the Common Stock over the Valuation Period.

 

The increase to
the Conversion Rate under the preceding paragraph shall occur on the last Trading Day of the Valuation Period; provided that
(x) in respect of any conversion of Notes for which Physical Settlement is applicable, if the relevant Conversion Date occurs
during the Valuation Period, references in the portion of this Section 13.04(c) related to Spin-Offs to a “10 consecutive
Trading Day period” shall be deemed to be replaced with such lesser number of Trading Days as have elapsed between the Ex-Dividend
Date of such Spin-Off and the Conversion Date in determining the Conversion Rate and (y) in respect of any conversion of Notes
for which Cash Settlement or Combination Settlement is applicable, for any Trading Day that falls within the relevant Observation
Period for such conversion and within the Valuation Period, the reference to “10” in the preceding paragraph shall
be deemed replaced with such lesser number of Trading Days as have elapsed between the Ex-Dividend Date for such Spin-Off and such
Trading Day in determining the Conversion Rate as of such Trading Day. If the Ex-Dividend Date of the Spin-Off is after the 10th
Trading Day immediately preceding, and including, the end of any Observation Period in respect of a conversion of Notes, references
to “10” or “10th” in the preceding paragraph and in this paragraph shall be deemed to be replaced, solely
in respect of that conversion of Notes, with such lesser number of Trading Days as have elapsed from, and including, the Ex-Dividend
Date for the Spin-Off to, and including, the last Trading Day of such Observation Period.

 

    128

     

    

 

For purposes of
this Section 13.04(c) (and subject in all respects to Section 13.11), rights, options or warrants distributed by
the Company to all holders of the Common Stock entitling them to subscribe for or purchase shares of the Company’s Capital
Stock, including Common Stock (either initially or under certain circumstances), which rights, options or warrants, until the occurrence
of a specified event or events (“Trigger Event”): (i) are deemed to be transferred with such shares of the Common
Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of the Common Stock, shall
be deemed not to have been distributed for purposes of this Section 14.04(c) (and no adjustment to the Conversion Rate
under this Section 13.04(c) will be required) until the occurrence of the earliest Trigger Event, whereupon such rights,
options or warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion
Rate shall be made under this Section 13.04(c). If any such right, option or warrant, including any such existing rights,
options or warrants distributed prior to the date of this Indenture, are subject to events, upon the occurrence of which such rights,
options or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date
of the occurrence of any and each such event shall be deemed to be the date of distribution and Ex-Dividend Date with respect to
new rights, options or warrants with such rights (in which case the existing rights, options or warrants shall be deemed to terminate
and expire on such date without exercise by any of the holders thereof). In addition, in the event of any distribution (or
deemed distribution) of rights, options or warrants, or any Trigger Event or other event (of the type described in the immediately
preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment
to the Conversion Rate under this Section 13.04(c) was made, (1) in the case of any such rights, options or warrants
that shall all have been redeemed or purchased without exercise by any holders thereof, upon such final redemption or purchase
(x) the Conversion Rate shall be readjusted as if such rights, options or warrants had not been issued and (y) the Conversion
Rate shall then again be readjusted to give effect to such distribution, deemed distribution or Trigger Event, as the case may
be, as though it were a cash distribution, equal to the per share redemption or purchase price received by a holder or holders
of Common Stock with respect to such rights, options or warrants (assuming such holder had retained such rights, options or warrants),
made to all holders of Common Stock as of the date of such redemption or purchase, and (2) in the case of such rights, options
or warrants that shall have expired or been terminated without exercise by any holders thereof, the Conversion Rate shall be readjusted
as if such rights, options and warrants had not been issued.

 

For purposes of Section 13.04(a), Section 13.04(b) and
this Section 13.04(c), if any dividend or distribution to which this Section 13.04(c) is applicable also includes
one or both of:

 

(A) a dividend or distribution of shares of
Common Stock to which Section 13.04(a) is applicable (the “Clause A Distribution”); or

 

(B) a dividend or distribution of rights, options
or warrants to which Section 13.04(b) is applicable (the “Clause B Distribution”),

 

then, in either case, (1) such dividend
or distribution, other than the Clause A Distribution and the Clause B Distribution, shall be deemed to be a dividend or distribution
to which this Section 13.04(c) is applicable (the “Clause C Distribution”) and any Conversion Rate adjustment
required by this Section 13.04(c) with respect to such Clause C Distribution shall then be made, and (2) the Clause
A Distribution and Clause B Distribution shall be deemed to immediately follow the Clause C Distribution and any Conversion Rate
adjustment required by Section 13.04(a) and Section 13.04(b) with respect thereto shall then be made, except
that, if determined by the Company (I) the “Ex-Dividend Date” of the Clause A Distribution and the Clause B Distribution
shall be deemed to be the Ex-Dividend Date of the Clause C Distribution and (II) any shares of Common Stock included in the
Clause A Distribution or Clause B Distribution shall be deemed not to be “outstanding immediately prior to the open of business
on such Ex-Dividend Date or Effective Date” within the meaning of Section 13.04(a) or “outstanding immediately
prior to the open of business on such Ex-Dividend Date” within the meaning of Section 13.04(b).

 

    129

     

    

 

(d) If any cash dividend or distribution
is made to all or substantially all holders of the Common Stock, the Conversion Rate shall be increased based on the following
formula:

 

 

where,

 

	CR0	 	=	 	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such dividend or distribution;
	CR’	 	=	 	the Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for such dividend or distribution;
	SP0	 	=	 	the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the Ex-Dividend Date for such dividend or distribution; and
	C	 	=	 	the amount in cash per share the Company distributes to all or substantially all holders of the Common Stock.

 

Any
increase pursuant to this Section 13.04(d) shall become effective immediately after the open of business on the Ex-Dividend
Date for such dividend or distribution. If such dividend or distribution is not so paid, the Conversion Rate shall be decreased,
effective as of the date the Board of Directors or a committee thereof determines not to make or pay such dividend or distribution,
to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. Notwithstanding
the foregoing, if “C” (as defined above) is equal to or greater than “SP0”
(as defined above), in lieu of the foregoing increase, each Holder of a Note shall receive, for each $1,000 principal amount of
Notes, at the same time and upon the same terms as holders of shares of the Common Stock, the amount of cash that such Holder would
have received if such Holder owned a number of shares of Common Stock equal to the Conversion Rate on the Ex-Dividend Date for
such cash dividend or distribution.

 

(e) If
the Company or any of its Subsidiaries make a payment in respect of a tender or exchange offer for the Common Stock, to the extent
that the cash and value of any other consideration included in the payment per share of the Common Stock exceeds the average of
the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period commencing on, and including, the
Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer,
the Conversion Rate shall be increased based on the following formula:

 

 

    130

     

    

 

where,

 

	CR0	 	=	 	the Conversion Rate in effect immediately prior to the close of business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires;
	CR’	 	=	 	the Conversion Rate in effect immediately after the close of business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires;
	AC	 	=	 	the aggregate value of all cash and any other consideration (as determined by the Board of Directors or a committee thereof) paid or payable for shares of Common Stock purchased in such tender or exchange offer;
	OS0	 	=	 	the number of shares of Common Stock outstanding immediately prior to the date such tender or exchange offer expires (prior to giving effect to the purchase of all shares of Common Stock accepted for purchase or exchange in such tender or exchange offer);
	OS’	 	=	 	the number of shares of Common Stock outstanding immediately after the date such tender or exchange offer expires (after giving effect to the purchase of all shares of Common Stock accepted for purchase or exchange in such tender or exchange offer); and
	SP’	 	=	 	the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the date such tender or exchange offer expires.

 

The
increase to the Conversion Rate under this Section 13.04(e) shall occur at the close of business on the 10th Trading
Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires; provided that
(x) in respect of any conversion of Notes for which Physical Settlement is applicable, if the relevant Conversion Date occurs
during the 10 Trading Days immediately following, and including, the Trading Day next succeeding the expiration date of any tender
or exchange offer, references in this Section 13.04(e) with respect to “10” or “10th” shall be
deemed replaced with such lesser number of Trading Days as have elapsed between the date that such tender or exchange offer expires
and the Conversion Date in determining the Conversion Rate and (y) in respect of any conversion of Notes for which Cash Settlement
or Combination Settlement is applicable, for any Trading Day that falls within the relevant Observation Period for such conversion
and within the 10 Trading Days immediately following, and including, the Trading Day next succeeding the date such tender or exchange
offer expires, references to “10” or “10th” in the preceding paragraph and this paragraph shall be deemed
replaced with such lesser number of Trading Days as have elapsed between the date such tender or exchange offer expires and such
Trading Day in determining the Conversion Rate as of such Trading Day. In addition, if the Trading Day next succeeding the date
such tender or exchange offer expires is after the 10th Trading Day immediately preceding, and including, the end of any Observation
Period in respect of a conversion of Notes, references to “10” or “10th” in the preceding paragraph and
this paragraph shall be deemed to be replaced, solely in respect of that conversion of Notes, with such lesser number of Trading
Days as have elapsed from, and including, the Trading Day next succeeding the date such tender or exchange offer expires to, and
including, the last Trading Day of such Observation Period.

 

    131

     

    

 

(f) Notwithstanding
this Section 13.04 or any other provision of this Indenture or the Notes, if a Conversion Rate adjustment becomes effective
on any Ex-Dividend Date, and a Holder that has converted its Notes on or after such Ex-Dividend Date and on or prior to the related
Record Date would be treated as the record holder of the shares of Common Stock as of the related Conversion Date as described
under Section 13.02(i) based on an adjusted Conversion Rate for such Ex-Dividend Date, then, notwithstanding the Conversion
Rate adjustment provisions in this Section 13.04, the Conversion Rate adjustment relating to such Ex-Dividend Date shall not
be made for such converting Holder. Instead, such Holder shall be treated as if such Holder were the record owner of the shares
of Common Stock on an unadjusted basis and participate in the related dividend, distribution or other event giving rise to such
adjustment.

 

(g) Except
as stated herein, the Company shall not adjust the Conversion Rate for the issuance of shares of the Common Stock or any securities
convertible into or exchangeable for shares of the Common Stock or the right to purchase shares of the Common Stock or such convertible
or exchangeable securities.

 

(h) In addition
to those adjustments required by clauses (a), (b), (c), (d) and (e) of this Section 13.04, and to the extent permitted
by applicable law and subject to the applicable rules of any exchange on which any of the Company’s securities are then
listed, the Company from time to time may increase the Conversion Rate by any amount for a period of at least 20 Business Days
if the Board of Directors determines that such increase would be in the Company’s best interest. In addition, to the extent
permitted by applicable law and subject to the applicable rules of any exchange on which any of the Company’s securities
are then listed, the Company may (but is not required to) increase the Conversion Rate to avoid or diminish any income tax to holders
of Common Stock or rights to purchase Common Stock in connection with a dividend or distribution of shares of Common Stock (or
rights to acquire shares of Common Stock) or similar event. Whenever the Conversion Rate is increased pursuant to either of
the preceding two sentences, the Company shall deliver to the Holder of each Note at its last address appearing on the Note Register
a notice of the increase at least 15 days prior to the date the increased Conversion Rate takes effect, and such notice shall state
the increased Conversion Rate and the period during which it will be in effect.

 

(i) Notwithstanding
anything to the contrary in this Article 13, the Conversion Rate shall not be adjusted:

 

(i) upon
the issuance of any shares of Common Stock pursuant to any present or future plan providing for the reinvestment of dividends or
interest payable on the Company’s securities and the investment of additional optional amounts in shares of Common Stock
under any plan;

 

(ii) upon
the issuance of any shares of Common Stock or options or rights to purchase those shares pursuant to any present or future employee,
director or consultant benefit plan or program of or assumed by the Company or any of the Company’s Subsidiaries;

 

(iii) upon
the issuance of any shares of the Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible
security not described in clause (ii) of this subsection and outstanding as of the date the Notes were first issued;

 

(iv) solely
for a change in the par value of the Common Stock;

 

(v) for
the Rights Offering, if any; or

 

    132

     

    

 

(vi) for
accrued and unpaid interest, if any.

 

(j) All calculations
and other determinations under this Article 13 shall be made by the Company and shall be made to the nearest one-ten thousandth
(1/10,000th) of a share.

 

(k) Whenever
the Conversion Rate is adjusted as herein provided, the Company shall promptly file with the Trustee (and the Conversion Agent
if not the Trustee) an Officers’ Certificate setting forth the Conversion Rate after such adjustment and setting forth a
brief statement of the facts requiring such adjustment. Unless and until a Responsible Officer of the Trustee shall have received
such Officers’ Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion Rate and
may assume without inquiry that the last Conversion Rate of which it has knowledge is still in effect. Promptly after delivery
of such certificate, the Company shall prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted Conversion
Rate and the date on which each adjustment becomes effective and shall deliver such notice of such adjustment of the Conversion
Rate to each Holder at its last address appearing on the Note Register. Failure to deliver such notice shall not affect the
legality or validity of any such adjustment.

 

(l) For purposes
of this Section 13.04, the number of shares of Common Stock at any time outstanding shall not include shares of Common Stock
held in the treasury of the Company so long as the Company does not pay any dividend or make any distribution on shares of Common
Stock held in the treasury of the Company, but shall include shares of Common Stock issuable in respect of scrip certificates issued
in lieu of fractions of shares of Common Stock.

 

Section 13.05     Adjustment
of Prices.

 

Whenever any provision
of this Indenture requires the Company to calculate the Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values
or the Daily Settlement Amounts over a span of multiple days (including an Observation Period and the period for determining the
Stock Price for purposes of a Make-Whole Fundamental Change), the Board of Directors shall make appropriate adjustments to each
to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion
Rate where the Ex-Dividend Date, Effective Date or expiration date, as the case may be, of the event occurs, at any time during
the period when the Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or the Daily Settlement Amounts are
to be calculated.

 

Section 13.06     Shares
to Be Fully Paid.

 

The Company shall provide,
free from preemptive rights, out of its authorized but unissued shares or shares held in treasury, sufficient shares of Common
Stock to provide for conversion of the Notes from time to time as such Notes are presented for conversion (assuming delivery of
the maximum number of Additional Shares pursuant to Section 13.03 and that at the time of computation of such number of shares,
all such Notes would be converted by a single Holder and that Physical Settlement were applicable).

 

    133

     

    

 

Section 13.07     Effect
of Recapitalizations, Reclassifications, and Changes of the Common Stock.

 

(a) In the
case of:

 

(i) any
recapitalization, reclassification or change of the Common Stock (other than changes resulting from a subdivision or combination),

(ii) any
consolidation, merger or combination involving the Company,

(iii) any
sale, lease or other transfer to a third party of the consolidated assets of the Company and the Company’s Subsidiaries substantially
as an entirety or

(iv) any
statutory share exchange,

 

in each case,
as a result of which the Common Stock would be converted into, or exchanged for, stock, other securities, other property or assets
(including cash or any combination thereof) (any such event, a “Merger Event”), then, at and after the effective time
of such Merger Event, the right to convert each $1,000 principal amount of Notes shall be changed into a right to convert such
principal amount of Notes into the kind and amount of shares of stock, other securities or other property or assets (including
cash or any combination thereof) that a holder of a number of shares of Common Stock equal to the Conversion Rate immediately prior
to such Merger Event would have owned or been entitled to receive (the “Reference Property,” with each “unit
of Reference Property” meaning the kind and amount of Reference Property that a holder of one share of Common Stock is entitled
to receive) upon such Merger Event and, prior to or at the effective time of such Merger Event, the Company or the successor or
purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture providing for such change in the
right to convert each $1,000 principal amount of Notes; provided, however, that at and after the effective
time of the Merger Event (A) the Company shall continue to have the right to determine the form of consideration to be paid
or delivered, as the case may be, upon conversion of Notes in accordance with Section 13.02 and (B) (I) any amount
payable in cash upon conversion of the Notes in accordance with Section 14.02 shall continue to be payable in cash, (II) any
shares of Common Stock that the Company would have been required to deliver upon conversion of the Notes in accordance with Section 13.02
(including, if applicable, any shares of Common Stock deliverable in connection with any Make-Whole Premium) or in connection with
any delivery of shares of Common Stock in respect of any Make-Whole Premium deliverable upon a conversion price Redemption shall
instead be deliverable in the amount and type of Reference Property that a holder of that number of shares of Common Stock would
have been entitled to receive in such Merger Event and (III) the Daily VWAP shall be calculated based on the value of a unit
of Reference Property.

 

If
the Merger Event causes the Common Stock to be converted into, or exchanged for, the right to receive more than a single type of
consideration (determined based in part upon any form of stockholder election), then (i) the Reference Property into which
the Notes will be convertible shall be deemed to be (x) the weighted average of the types and amounts of consideration received
by the holders of Common Stock that affirmatively make such an election or (y) if no holders of Common Stock affirmatively
make such an election, the types and amounts of consideration actually received by the holders of Common Stock, and (ii) the
unit of Reference Property for purposes of the immediately preceding paragraph shall refer to the consideration referred to in
clause (i) attributable to one share of Common Stock. If the holders of the Common Stock receive only cash in such Merger
Event, then for all conversions for which the relevant Conversion Date occurs after the effective date of such Merger Event (A) the
consideration due upon conversion of each $1,000 principal amount of Notes shall be solely cash in an amount equal to the Conversion
Rate in effect on the Conversion Date (as may be increased by any Additional Shares pursuant to Section 14.03), multiplied
by the price paid per share of Common Stock in such Merger Event and (B) the Company shall satisfy the Conversion
Obligation by paying cash to converting Holders on the third Business Day immediately following the relevant Conversion Date. The
Company shall notify Holders, the Trustee and the Conversion Agent (if other than the Trustee) of such weighted average as soon
as practicable after such determination is made.

 

    134

     

    

 

Such supplemental indenture described in
the second immediately preceding paragraph shall provide for anti-dilution and other adjustments that shall be as nearly equivalent
as is possible to the adjustments provided for in this Article 13. If, in the case of any Merger Event, the Reference
Property includes shares of stock, securities or other property or assets (including cash or any combination thereof) of a Person
other than the successor or purchasing corporation, as the case may be, in such Merger Event, then such supplemental indenture
shall also be executed by such other Person and shall contain such additional provisions to protect the interests of the Holders
of the Notes, including the right of Holders to require the Company to repurchase their Notes upon a Change of Control as described
in Section 4.14, as the Board of Directors shall reasonably consider necessary by reason of the foregoing. The Company will
not become a party to any Merger Event unless its terms are consistent with the foregoing.

 

(b) When the Company
executes a supplemental indenture pursuant to subsection (a) of this Section 13.07, the Company shall promptly file with
the Trustee an Officers’ Certificate briefly stating the reasons therefor, the kind or amount of cash, securities or property
or asset that will comprise a unit of Reference Property after any such Merger Event, any adjustment to be made with respect thereto
and that all conditions precedent have been complied with, and shall promptly deliver notice thereof to all Holders. The Company
shall cause notice of the execution of such supplemental indenture to be delivered to each Holder, at its address appearing on
the Note Register provided for in this Indenture, within 20 days after execution thereof. Failure to deliver such notice shall
not affect the legality or validity of such supplemental indenture.

 

(c) The Company
shall not become a party to any Merger Event unless its terms are consistent with this Section 13.07. None of the foregoing
provisions shall affect the right of a holder of Notes to convert its Notes into cash, shares of Common Stock or a combination
of cash and shares of Common Stock, as applicable, as set forth in Section 13.01 and Section 13.02 prior to the effective
date of such Merger Event.

 

(d) The above
provisions of this Section shall similarly apply to successive Merger Events.

 

Section 13.08     Certain
Covenants.

 

(a) The Company
covenants that all shares of Common Stock issued upon conversion of Notes or in respect of any Make-Whole Premium will be fully
paid and non-assessable by the Company and free from all taxes, liens and charges with respect to the issue thereof.

 

(b) The Company
covenants that, if any shares of Common Stock to be provided for the purpose of conversion of Notes hereunder or in respect of
any Make-Whole Premium require registration with or approval of any governmental authority under any federal or state law before
such shares of Common Stock may be validly issued upon conversion or in respect of any Make-Whole Premium, the Company will, to
the extent then permitted by the rules and interpretations of the Commission, secure such registration or approval, as the
case may be.

 

    135

     

    

 

(c) The Company
further covenants that if at any time the Common Stock shall be listed on any national securities exchange or automated quotation
system the Company will list and keep listed, so long as the Common Stock shall be so listed on such exchange or automated quotation
system, any Common Stock issuable upon conversion of the Notes or in respect of any Make-Whole Premium.

 

Section 13.09     Responsibility
of Trustee.

 

The Trustee and any
Conversion Agent shall not at any time be under any duty or responsibility to any Holder to determine the Conversion Rate (or any
adjustment thereto) or whether any facts exist that may require any adjustment (including any increase) of the Conversion Rate,
or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed,
or herein or in any supplemental indenture provided to be employed, in making the same. The Trustee and any Conversion Agent shall
not be accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of any securities,
property or cash that may at any time be issued or delivered upon the conversion of any Note; and the Trustee and any other Conversion
Agent make no representations with respect thereto. Neither the Trustee nor any Conversion Agent shall be responsible for any failure
of the Company to issue, transfer or deliver any shares of Common Stock or stock certificates or other securities or property or
cash upon the surrender of any Note for the purpose of conversion or to comply with any of the duties, responsibilities or covenants
of the Company contained in this Article. Without limiting the generality of the foregoing, neither the Trustee nor any Conversion
Agent shall be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture
entered into pursuant to Section 14.07 relating either to the kind or amount of shares of stock or securities or property
(including cash) receivable by Holders upon the conversion of their Notes after any event referred to in such Section 14.07
or to any adjustment to be made with respect thereto, but, subject to the provisions of Section 7.01, may accept (without
any independent investigation) as conclusive evidence of the correctness of any such provisions, and shall be protected in conclusively
relying upon, the Officers’ Certificate (which the Company shall be obligated to file with the Trustee prior to the execution
of any such supplemental indenture in addition to any other deliverables required hereunder in connection with the execution of
such supplemental indenture) with respect thereto.

 

Section 13.10     Notice
to Holders Prior to Certain Actions.

 

In case of any:

 

(a) action by
the Company or one of its Subsidiaries that would require an adjustment in the Conversion Rate pursuant to Section 13.04 or
Section 13.11;

 

(b) Merger Event;
or

 

    136

     

    

 

(c) voluntary
or involuntary dissolution, liquidation or winding-up of the Company or any of its Subsidiaries;

 

then, in each case
(unless notice of such event is otherwise required pursuant to another provision of this Indenture), the Company shall cause to
be filed with the Trustee and the Conversion Agent (if other than the Trustee) and to be delivered to each Holder at its address
appearing on the Note Register, as promptly as possible but in any event at least 20 days prior to the applicable date hereinafter
specified, a notice stating (i) the date on which a record is to be taken for the purpose of such action by the Company or
one of its Subsidiaries or, if a record is not to be taken, the date as of which the holders of Common Stock of record are to be
determined for the purposes of such action by the Company or one of its Subsidiaries, or (ii) the date on which such Merger
Event, dissolution, liquidation or winding-up is expected to become effective or occur, and the date as of which it is expected
that holders of Common Stock of record shall be entitled to exchange their Common Stock for securities or other property deliverable
upon such Merger Event, dissolution, liquidation or winding-up. Failure to give such notice, or any defect therein, shall
not affect the legality or validity of such action by the Company or one of its Subsidiaries, Merger Event, dissolution, liquidation
or winding-up.

 

Section 13.11     Stockholder
Rights Plans.

 

If the Company has
a stockholder rights plan in effect upon conversion of the Notes, each share of Common Stock, if any, issued upon such conversion
shall be entitled to receive the appropriate number of rights, if any, and the certificates representing the Common Stock issued
upon such conversion shall bear such legends, if any, in each case as may be provided by the terms of any such stockholder rights
plan, as the same may be amended from time to time. However, if, prior to any conversion of Notes, the rights have separated from
the shares of Common Stock in accordance with the provisions of the applicable stockholder rights plan, the Conversion Rate shall
be adjusted at the time of separation as if the Company distributed to all or substantially all holders of the Common Stock Distributed
Property as provided in Section 13.04(c), subject to readjustment in the event of the expiration, termination or redemption
of such rights.

 

Section 13.12     [Intentionally
Omitted.]

 

Section 13.13     Company
Conversion.

 

(a)            On
or after the day that is the eighteen (18) month anniversary of the Issue Date, the Company may require the conversion of all or
part of the Notes, at its option, if the Company’s Common Stock, as determined by the Company, has a twenty-day volume weighted
average price (“VWAP”) of at least 175% of the conversion price then in effect ending on, and including, the
trading day immediately preceding the date on which the Company provides notice of conversion (an “Optional Conversion”).
If the Company undergoes an Optional Conversion prior to the third anniversary of the Issue Date, holders of the Notes will be
entitled to a make-whole premium payment in cash equal to the Applicable Premium amount.

 

(b)            In
the case of any Optional Conversion, the Company will provide note less than 45 nor more than 50 scheduled trading days’
notice before the conversion date to the Trustee, the Paying Agent, and each holder of Notes. The conversion price will be equal
to 100% of the principal amount of the Notes to be converted, plus any accrued and unpaid interest to, but excluding, the date
of redemption (unless the date of redemption falls after a regular record date but on or prior to the immediately succeeding interest
payment date, in which case the Company shall pay the full amount of accrued and unpaid interest to the holder of record as of
the close of business on such regular record date, and the redemption price will be equal to 100% of the principal amount of the
Notes to be redeemed). The date of redemption must be on a Business Day and may not fall after the Maturity Date.

 

    137

     

    

 

(c)            If
pursuant to an Optional Conversion the Company elects to convert fewer than all of the outstanding Notes, the Trustee shall select
the Notes to be converted (in principal amounts of $1,000 or multiples thereof) by lot, on a pro rata basis or another method the
Trustee considers to be fair and appropriate, in each case, with respect to Global Notes, in accordance and subject to applicable
DTC procedures or requirements.

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

 

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

 

(i)            INTEREST.
ION Geophysical Corporation, a Delaware corporation (the “Company”), promises to pay or cause to be paid interest
on the principal amount of this Note at 8.00% per annum from [●], 2021 until maturity. The Company will pay interest semi-annually
in arrears on June 15 and December 15 of each year, or if any such day is not a Business Day, on the next succeeding
Business Day (each, an “Interest Payment Date”). Interest on the Notes will accrue from the most recent date
to which interest has been paid or, if no interest has been paid, from the date of issuance; provided that, if 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 June 15,
2021. The Company will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal
at a rate that is 1% higher than the then applicable interest rate on the Notes to the extent lawful; 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 comprised of twelve
30-day months.

 

(ii)            METHOD
OF PAYMENT. The Company will pay interest on the Notes (except defaulted interest) to the Persons who are registered Holders
of Notes at the close of business on the June 1 and December 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 Paying Agent and Registrar within the City and State of New York, or, at the option of the Company,
payment of interest 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, premium on, if
any, and interest 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.

 

(iii)            PAYING
AGENT AND REGISTRAR. Initially, UMB Bank, National Association, the Trustee under the Indenture, will act as Paying Agent and
Registrar. The Company may change the Paying Agent or Registrar without prior notice to the Holders of the Notes. The Company or
any of its Subsidiaries may act as Paying Agent or Registrar.

 

    A-2

     

    

 

(iv)            INDENTURE
AND SECURITY DOCUMENTS. The Company has issued the Notes under an Indenture dated as of [●], 2021 (the “Indenture”)
among the Company, the Guarantors and the Trustee and the Collateral Agent. The terms of the Notes include those stated in the
Indenture and those made part of the Indenture by reference to the TIA. The Notes are subject to all such terms, and Holders are
referred to the Indenture and the TIA for a statement of such terms. To the extent any provision of this Note conflicts with the
express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. The Notes are secured obligations
of the Company. The Notes are secured by a second priority Lien in and on all the Collateral pursuant to the Security Documents
referred to in the Indenture.

 

(v)            OPTIONAL
REDEMPTION.

 

(A)            At
any time prior to December 15, 2023, the Company may on any one or more occasions redeem all or a part of the aggregate principal
amount of Notes issued under the Indenture, upon not less than 30 nor more than 60 days’ notice, at a redemption price equal
to 100.000% of the principal amount of the Notes redeemed, plus (1) the excess of (a) the present value of the Notes
to be redeemed at such redemption date of (i) the redemption price of the Notes to be redeemed at December 15, 2023 plus
(ii) all required interest payments due on the Notes to be redeemed through December 15, 2023 (excluded accrued but unpaid

such redemption date plus 50 basis points over (b) the principal amount of the Notes (the “Applicable Premium”)
and (2) accrued and unpaid interest to the date of redemption (subject to the rights of Holders of Notes on the relevant record
date to receive interest on the relevant Interest Payment Date).

 

(B)            At
any time on or after to December 15, 2023, the Company may on any one or more occasions redeem all or a part of the Notes,
upon not less than 30 nor more than 60 days’ notice, at a redemption price equal to 100% of the principal amount of the Notes

rights of Holders on the relevant record date to receive interest due on the relevant Interest Payment Date.

 

(C)            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 the applicable redemption date.

 

(vi)            MANDATORY
REDEMPTION. Except as set forth below under Sections [4.10] and [4.14] of the Indenture, the Company is not required to make
mandatory redemption or sinking fund payments with respect to the Notes.

 

    A-3

     

    

 

(vii)            CONVERSION
RIGHTS.

 

(A)            Subject
to the provisions of the Indenture, the Holder hereof has the right, at its option, at any time prior to the close of business
on the Business Day immediately preceding the Maturity Date, to convert any Notes or any portion thereof that is $1,000 or an integral
multiple thereof, into cash, shares of Common Stock, or a combination of cash and shares of Common Stock, as applicable, at the
Conversion Rate specified in the Indenture, as adjusted from time to time as provided in the Indenture.

 

(viii)            REPURCHASE
AT THE OPTION OF HOLDER.

 

(A)            Upon
the occurrence of a Change of Control, the Company will be required to make an offer (a “Change of Control Offer”)
to each Holder to repurchase all or any part (equal to $1,000 or an integral multiple of $1,000 in excess thereof (or the portion)
(calculated after giving effect to any issuance of Additional Notes) 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 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 ten days following any Change of Control, the
Company will mail a notice to each Holder setting forth the procedures governing the Change of Control Offer as required by the
Indenture.

 

(B)            If
the Company or a Restricted Subsidiary of the Company consummates any Asset Sales, within five days of each date on which the aggregate
amount of Excess Proceeds exceeds $1.0 million, the Company may (and when Excess Proceeds exceeds $10.0 million, the Company shall),
to the extent permitted by the Intercreditor Agreement and the Credit Agreement, each as in effect on the Issue Date, make an Asset
Sale Offer to all Holders of Notes and all holders of Second Lien Debt containing provisions similar to those set forth in the
Indenture with respect to offers to purchase, prepay or redeem with the proceeds of sales of assets to purchase, prepay or redeem
the maximum principal amount of Notes and such other Second Lien Debt (plus all accrued interest on the Indebtedness and the amount
of all fees and expenses, including premiums, incurred in connection therewith) that may be purchased, prepaid or redeemed out
of the Excess Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of the principal amount, plus accrued and
unpaid interest, if any, to the date of purchase, prepayment or redemption, subject to the rights of Holders of Notes on the relevant
record date to receive interest due on the relevant interest payment date, and will be payable in cash. If any Excess Proceeds
remain after consummation of an Asset Sale Offer (or expiration of the offer if no Holder accepts), 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 Second
Lien Debt tendered in (or required to be prepaid or redeemed in connection with) such Asset Sale Offer exceeds the amount of Excess
Proceeds, the Company will select the Notes and such other Second Lien Debt to be purchased on a pro rata basis (except
that any Notes represented by a note in global form will be selected by such method as DTC or its nominee or successor may require),
based on the amounts tendered or required to be prepaid or redeemed (with such adjustments as may be deemed appropriate by the
Company so that only Notes in denominations of $1,000, or an integral multiple of $1,000 in excess thereof, will be purchased).
Upon completion of each Asset Sale Offer (or expiration of the offer if no Holder accepts), the amount of Excess Proceeds will
be reset at zero. 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.

 

    A-4

     

    

 

(ix)            NOTICE
OF REDEMPTION. At least 30 days but not more than 60 days before a redemption date, the Company will mail or cause to be mailed,
by first class mail, a notice of redemption to each Holder whose Notes are to be redeemed at its registered address, except that
redemption notices may be mailed more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance
of the Notes or a satisfaction and discharge of the Indenture pursuant to Articles [8] or [12] thereof. Notes and portions of Notes
selected will be in amounts of $1,000 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 shall be redeemed or purchased. Notice
of any redemption, including, without limitation, upon an Equity Offering, may, at the Company’s discretion, be subject to
one or more conditions precedent, including, but not limited to, completion of the related Equity Offering.

 

(x)            DENOMINATIONS,
TRANSFER, EXCHANGE. The Notes are in registered form in minimum denominations of $1,000 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 next succeeding Interest Payment Date.

 

(xi)            PERSONS
DEEMED OWNERS. The registered Holder of a Note may be treated as the owner of it for all purposes. Only registered Holders
have rights under the Indenture.

 

    A-5

     

    

 

(xii)            AMENDMENT,
SUPPLEMENT AND WAIVER. Subject to certain exceptions, the Indenture, the Notes, the Note Guarantees or any other Note Documents
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 Additional Notes, if any, voting as a single class, and any existing Default or Event of Default or
compliance with any provision of the Indenture or the Notes or the Note Guarantees may be waived with the consent of the Holders
of a majority in aggregate principal amount of the then outstanding Notes including Additional Notes, if any, voting as a single
class. Without the consent of any Holder of Notes, the Indenture, the Notes, the Note Guarantees or any other Note Documents 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 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 Holder, to comply with the requirements of the SEC in order to effect or maintain the qualification
of the Indenture under the TIA, to conform the text of the Indenture, the Notes, the Note Guarantees or the Security Documents
to any provision of the “Description of the New Notes” section of the Offer to Exchange, relating to the initial offering
of the Notes, to the extent that such provision in that “Description of Notes” was intended to be a verbatim recitation
of a provision of the Indenture, the Notes, the Note Guarantees or the Security Documents, which intent shall be evidenced by an
Officers’ Certificate to that effect, to enter into additional or supplemental security documents, to make, complete or confirm
any grant of Collateral permitted or required by the Indenture or any of the Security Documents or any release of Collateral that
becomes effective as set forth in the Indenture or any of the Security Documents, to provide for the issuance of Additional Notes
in accordance with the limitations set forth in the Indenture, or to allow any Guarantor to execute a supplemental indenture to
the Indenture and/or a Note Guarantee with respect to the Notes. In determining whether the Holders of the required principal amount
of Notes have concurred in any direction, wavier, or consent, Notes owned by the Company or any Guarantor, or any of their respective
Subsidiaries, 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 receives
an Officers’ Certificate from the Company that such Notes are so owned will be so disregarded.

 

    A-6

     

    

 

(xiii)            DEFAULTS
AND REMEDIES. Events of Default include: (a) default for 30 days in the payment when due of interest on the Notes; (b) default
in the payment when due (at maturity, upon redemption or otherwise) of the principal of, or premium on, if any, the Notes, (c) failure
by the Company or any of its Restricted Subsidiaries to comply with the provisions of Sections [4.07, 4.09, 4.10, 4.14, or 5.01]
of the Indenture; (d) (1) failure by the Company or any of its Restricted Subsidiaries for 60 days after notice to the
Company by the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding voting as a single
class to comply with any of the other agreements in the Indenture or the Security Documents, or (2) failure by the Company
for 180 days after notice from the Trustee or Holders of at least 25% in aggregate principal amount of the Notes then outstanding
to comply with the provisions of Section [4.03] of the Indenture; (e) default under certain other agreements relating
to Indebtedness of the Company which default is a Payment Default or results in the acceleration of such Indebtedness prior to
its express maturity; (f) 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 $20.0 million (to the extent not covered by insurance by a reputable
and creditworthy insurer as to which the insurer has not disclaimed coverage), which judgments are not paid, discharged or stayed,
for a period of 60 days; (g) subject to certain exceptions and except as permitted by the Indenture, if any security document
ceases for any reason to be fully enforceable, certain security interests created by any security documents cease to be in full
force and effect, or the repudiation by the Company or any other Guarantor of any of their obligations under any security documents;
(h) except as permitted by the Indenture, any Note Guarantee is held in any judicial proceeding to be unenforceable or invalid
or ceases for any reason to be in full force and effect, or any Guarantor, or any Person acting on behalf of any Guarantor, denies
or disaffirms its obligations under its Note Guarantee; and (i) certain events of bankruptcy or insolvency 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. In the case of an Event of Default arising from certain events of bankruptcy
or insolvency 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. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. Subject
to certain limitations, Holders of a majority in aggregate principal amount of the then outstanding Notes may direct the time,
method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power
conferred on it. The Trustee may withhold from Holders of the Notes notice of any continuing Default or Event of Default (except
a Default or Event of Default relating to the payment of principal, premium, if any, or interest) if it determines that withholding
notice is in their interest. The Holders of a majority in aggregate principal amount of the then outstanding Notes by notice to
the Trustee may, on behalf of all the Holders of Notes, rescind an acceleration or waive an existing Default or Event of Default
and its respective consequences under the Indenture except a continuing Default or Event of Default in the payment of principal
of, premium on, if any, or interest on, the Notes (including in connection with an offer to purchase). The Company is required
to deliver to the Trustee annually a statement regarding compliance with the Indenture, and the Company is required, upon becoming
aware of any Default or Event of Default, to deliver to the Trustee a statement specifying such Default or Event of Default.

 

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

 

(xv)            NO
RECOURSE AGAINST OTHERS. No director, officer, employee, incorporator or other owner of Capital Stock of the Company or any
Guarantor, as such, will have any liability for any obligations of the Company or the Guarantors under the Notes, the Indenture,
the Note Guarantees, the Note Documents or for any claim based on, in respect of, or by reason of, such obligations or their creation.
Each Holder of Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration
for issuance of the Notes. The waiver may not be effective to waive liabilities under the federal securities laws.

notice of redemption, and reliance may be placed only on the other identification numbers placed thereon.

2021 providing for the issuance of 8.00% Senior Secured Second Priority Notes due 2025 (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
