or in part, except the unredeemed portion of any Note being redeemed in part or (C) to register the transfer of or to exchange
any Note between a Record Date and the next succeeding Interest Payment Date.

 

(vi)              Prior

Person in whose name any Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal
of (and premium, if any) and interest on such Notes and for all other purposes, and none of the Trustee, any Agent or the Company

(vii)             Upon
surrender for registration of transfer of any Note at the office or agency of the Company designated pursuant to Section 4.02,
the Company shall execute, and the Trustee shall authenticate and mail, in the name of the designated transferee or transferees,

    -45-

     

    

 

(viii)           At
the option of the Holder, Notes may be exchanged for other Notes of like tenor, in any authorized denomination or denominations
of a like aggregate principal amount upon surrender of the Notes to be exchanged at the office or agency of the Company designated

than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if
and when expressly required by the terms of this Indenture, and to examine the same to determine substantial compliance as to form

		Section
                          2.07	Replacement
                                         Notes.

 

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

 

Every replacement Note
is a contractual obligation of the Company and shall 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 cancelled by it, those delivered to it for cancellation,
those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described
in this Section 2.08 as not outstanding. Except as set forth in Section 2.09, a Note does not cease to be outstanding because the
Company or an Affiliate of the Company holds the Note.

 

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

 

    -46-

     

    

 

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

 

If the Paying Agent (other
than the Company, a Subsidiary of the Company 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 shall be deemed to be no longer outstanding
and shall 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 by any Affiliate of the Company, shall be considered as though not outstanding, except that for the purposes of determining
whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes that a Responsible Officer
of the Trustee actually knows are so owned shall be so disregarded. Notes so owned which have been pledged in good faith shall
not be disregarded if the pledgee establishes to the satisfaction of the Trustee the pledgee’s right to deliver any such
direction, waiver or consent with respect to the Notes and that the pledgee is not the Company or any other obligor upon the Notes
or any Affiliate of the Company or of such other obligor.

 

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

 

Holders of temporary
Notes shall be entitled to all of the benefits accorded to Holders of Notes under this Indenture.

 

		Section 2.11	Cancellation.

 

The Company at any time
may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent shall forward to the Trustee any Notes surrendered
to them for registration of transfer, exchange or payment. The Trustee or, at the direction of the Trustee, the Registrar or the
Paying Agent and no one else shall cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or
cancellation and shall destroy cancelled Notes in accordance with its customary procedures (subject to the record retention requirement
of the Exchange Act and the Trustee). Certification of the cancellation of all cancelled Notes shall be delivered to the Company
upon written request. The Company may not issue new Notes to replace Notes that it has paid or that have been delivered to the
Trustee for cancellation.

 

		Section 2.12	Defaulted Interest.

 

If the Company
defaults in a payment of interest on the Notes, the Company shall pay the defaulted interest in any lawful manner plus, to
the extent lawful, interest payable on the defaulted interest to the Persons who are Holders on a subsequent special record
date, in each case at the rate provided in the Notes and in Section 4.01. The Company shall 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, and at the same time
the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of
such defaulted interest or shall make arrangements as are satisfactory to the Trustee for such deposit prior to the date of
the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such defaulted
interest as provided in this Section 2.12. The Company shall fix or cause to be fixed each such special record date and
payment date; provided that no such special record date shall be less than 10 days prior to the related payment date
for such defaulted interest. The Company shall promptly notify the Trustee of such special record date. 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) shall mail or cause to be mailed, first-class postage prepaid, to each Holder a notice at his or her
address as it appears in the Note Register that states the special record date, the related payment date and the amount of
such interest to be paid.

 

    -47-

     

    

 

Subject to the foregoing
provisions of this Section 2.12 and for greater certainty, each Note delivered under this Indenture upon registration of transfer
of or in exchange for or in lieu of any other Note shall carry the rights to interest accrued and unpaid, and to accrue, which
were carried by such other Note.

 

		Section 2.13	CUSIP and ISIN Numbers.

 

The Company in issuing
the Notes may use CUSIP and ISIN numbers (if then generally in use) and, if so, the Trustee shall use CUSIP and ISIN numbers in
notices of redemption as a convenience to Holders; provided that any such notice may state that no representation is made
as to the accuracy of such numbers either as printed on the Notes or as contained in any notice of redemption and that reliance
may be placed only on the other identification numbers printed on the Notes, and any such redemption shall not be affected by any
defect in or omission of such numbers. The Company will as promptly as practicable notify the Trustee of any change in the CUSIP
or ISIN numbers.

 

		Section 2.14	Global Notes.

 

Neither the Trustee nor
any Agent shall have any responsibility for any actions taken or not taken by the Depositary.

 

		Section 2.15	Issuance of Additional Notes.

 

After the Issue Date,
the Company shall be entitled, subject to its compliance with Section 4.12, to issue Additional Notes under this Indenture, which
Notes shall have identical terms as the Initial Notes other than with respect to the issue date, the issue price, the first Interest
Payment Date and the first date from which interest will accrue. With respect to any Additional Notes, the Company shall set forth
in a resolution of the Board of the Company and an Officers’ Certificate, a copy of each which shall be delivered to the
Trustee, the following information:

 

(a)                
the aggregate principal amount of such Additional Notes to be authenticated and delivered pursuant to this Indenture; and

 

(b)               
the issue price, the issue date and the CUSIP and ISIN numbers of such Additional Notes; provided that if any Additional
Notes are not fungible with the Initial Notes for U.S. federal income tax purposes, such Additional Notes will be issued as a separate
series under this Indenture and will have separate CUSIP and ISIN numbers from the Initial Notes.

 

    -48-

     

    

 

In authenticating
such Additional Notes, and accepting the additional responsibilities under this Indenture in relation to such Additional Notes,
the Trustee shall receive, and, subject to Section 7.01, shall be fully protected in relying upon:

 

(i)             
an Officers’ Certificate and Opinion of Counsel delivered in accordance with Section 13.02; and

 

(ii)             
such other documents as it may reasonably require.

 

ARTICLE 3

		Section 3.01	Notices to Trustee.

 

If the Company elects

		Section 3.02	Selection of Notes to Be
Redeemed or Purchased.

 

If less than all of the
Notes are to be redeemed or purchased in an offer to purchase at any time, the Trustee shall select the Notes to be redeemed or
purchased on a pro rata basis, by lot in accordance with the procedures of the Depositary or by such other method as the Trustee
in its sole discretion deems to be fair and appropriate. In the event of partial redemption or purchase by lot, the particular
Notes to be redeemed or purchased shall be selected, unless otherwise provided herein, not less than 30 nor more than 60 days prior
to the redemption date by the Trustee from the outstanding Notes not previously called for redemption or purchase.

 

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

 

		Section 3.03	Notice of Redemption.

deliver electronically in accordance with the procedures of the Depositary or mail or cause to be mailed by first-class mail,
postage prepaid, notices of redemption at least 30 days but not more than 60 days before the redemption date to each Holder
of Notes (with a copy to the Trustee) to be redeemed at such Holder’s registered address or otherwise in accordance
with the procedures of the Depositary, except that redemption notices may be delivered or mailed more than 60 days prior to a
redemption date if the notice is issued in connection with Article 8 or Article 12. Except as set forth in Section 3.07,
notices of redemption may not be conditional.

 

    -49-

     

    

 

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

 

(a)               
the redemption date;

 

(b)               
the redemption price if then ascertainable, and otherwise the appropriate method for calculation of the redemption price,
in which case the actual redemption price shall be set forth in an Officers’ Certificate delivered to the Trustee no later
than two (2) Business Days prior to the redemption date unless clause (2) of the definition of “Applicable Premium”
is applicable, in which case such Officers’ Certificate should be delivered on the redemption date;

 

(c)               
if any Note is to be redeemed in part only, the portion of the principal amount of that Note that is to be redeemed and
that, after the redemption date upon surrender of such Note, a new Note or Notes in a principal amount equal to the unredeemed
portion of the original Note representing the same indebtedness to the extent not redeemed will be issued in the name of the Holder
of the Notes upon cancellation of the original Note;

 

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

 

(e)

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

 

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

 

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

 

(j)

case such Notes become due on the redemption date. At the Company’s request, the Trustee shall give the notice of redemption
in the Company’s name and at the Company’s expense; provided that the Company shall have delivered to the Trustee,
at least five Business Days (or such shorter period as the Trustee may agree) before notice of redemption is required to be provided

		Section
                          3.04	Effect
of Notice of Redemption.

 

Once notice of redemption
is delivered or mailed in accordance with Section 3.03, Notes called for redemption become irrevocably due and payable on the date
fixed for redemption at the applicable redemption price, unless such redemption is conditioned on the happening of a future event,
in which case such Notes become due on the redemption date. The notice, if delivered or mailed in a manner herein provided, shall
be conclusively presumed to have been given, whether or not the Holder receives such notice. In any case, failure to give such
notice in accordance with this Indenture or any defect in the notice to the Holder of any Note designated for redemption in whole
or in part shall not affect the validity of the proceedings for the redemption of any other Note. Subject to Section 3.05, on and
after the redemption date interest ceases to accrue on Notes or portions of Notes called for redemption.

 

		Section 3.05	Deposit of Redemption or
                                         Purchase Price.

 

Prior to 10:00 a.m. (New
York City time) on the redemption date or purchase date, the Company shall deposit with the Trustee or with the Paying Agent money
sufficient to pay the redemption or purchase price of and accrued and unpaid interest on all Notes to be redeemed or purchased
on that date. The Trustee or the Paying Agent shall promptly return to the Company any money deposited with the Trustee or the
Paying Agent by the Company in excess of the amounts necessary to pay the redemption or purchase price of, and accrued and unpaid
interest on, all Notes to be redeemed or purchased.

 

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

 

		Section 3.06	Notes Redeemed or Purchased
                                         in Part.

 

Upon surrender of a Note
that is redeemed or purchased in part, the Company shall issue and the Trustee, upon receipt of an Authentication Order, shall
authenticate for the Holder at the expense of the Company a new Note equal in principal amount to the unredeemed or unpurchased
portion of the Note surrendered representing the same indebtedness to the extent not redeemed or purchased; provided that
each new Note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. It is understood that,
notwithstanding anything in this Indenture to the contrary, only an Authentication Order and not an Opinion of Counsel or Officers’
Certificate is required for the Trustee to authenticate such new Note.

the entire outstanding amount of Notes held by such Holder shall be redeemed or purchased); and

 

(ix)             
that Holders whose Notes were purchased only in part shall be issued new Notes equal in principal amount to the unpurchased
portion of the Notes surrendered (or transferred by book-entry transfer) representing the same indebtedness to the extent not repurchased.

 

(e)               
On or before the Asset Disposition Purchase Date, the Company will, to the extent lawful, accept for payment, on a pro rata
basis to the extent necessary, the Asset Disposition Offer Amount of Notes, Pari Passu Lien Obligations and Pari Passu Indebtedness
or portions thereof validly tendered and not properly withdrawn pursuant to the Asset Disposition Offer, or, if less than the Asset
Disposition Offer Amount has been validly tendered and not properly withdrawn, all Notes, Pari Passu Lien Obligations and Pari
Passu Indebtedness so tendered, in the case of the Notes in integral multiples of $1,000; provided that if, following repurchase
of a portion of a Note, the remaining principal amount of such Note outstanding immediately after such repurchase would be less
than $2,000, then the portion of such Note so repurchased shall be reduced so that the remaining principal amount of such Note
outstanding immediately after such repurchase is $2,000. The Company will deliver, or cause to be delivered, to the Trustee the
Notes so accepted and an Officers’ Certificate stating the aggregate principal amount of Notes so accepted and that such
Notes were accepted for payment by the Company in accordance with the terms of this Section 3.09. In addition, the Company will
deliver all certificates and instruments required, if any, by the agreements governing the Pari Passu Lien Obligations or Pari
Passu Indebtedness.

(f)                 The
Paying Agent or the Company, as the case may be, will promptly, but in no event later than five Business Days after
termination of the Asset Disposition Offer Period, mail (or otherwise deliver in accordance with the applicable procedures of
DTC) to each tendering Holder or holder or lender of Pari Passu Lien Obligations or Pari Passu Indebtedness, as the case may
be, an amount equal to the purchase price of the Notes, Pari Passu Lien Obligations or Pari Passu Indebtedness so validly
tendered and not properly withdrawn by such holder or lender, as the case may be, and accepted by the Company for purchase,
and if less than all of the Notes tendered are purchased pursuant to the Asset Disposition Offer, the Company will promptly
issue a new Note, and the Trustee, upon delivery of an authentication order from the Company, will authenticate and mail (or
otherwise deliver in accordance with the applicable procedures of DTC) (or cause to be transferred by book entry) such new
Note to such Holder (it being understood that, notwithstanding anything in this Indenture to the contrary, no Opinion of
Counsel or Officers’ Certificate will be required for the Trustee to authenticate and mail or deliver such new Note) in
a principal amount equal to any unpurchased portion of the Note surrendered; provided that each such new Note will be
in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. In addition, the Company will take any
and all other actions required by the agreements governing the Pari Passu Lien Obligations and Pari Passu Indebtedness. Any
Note not so accepted will be promptly mailed or delivered by the Company to the Holder thereof.

 

(g)               
The Company will comply, to the extent applicable, with the requirements of Rule 14e-1 under the Exchange Act and any other
securities laws or regulations in connection with the repurchase of Notes pursuant to a Collateral Disposition Offer or an Asset
Disposition Offer. To the extent that the provisions of any securities laws or regulations conflict with provisions of this Indenture,
the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations
under this Indenture by virtue of any conflict.

 

Other than as specifically
provided in this Section 3.09 or Section 4.10, any purchase pursuant to this Section 3.09 shall be made pursuant to the applicable
provisions of Sections 3.01 through 3.06.

Act or otherwise report on an annual and quarterly basis on forms provided for such annual and quarterly reporting pursuant to
the rules and regulations promulgated by the SEC, the Company will file with the SEC within the time periods specified in the SEC’s
rules and regulations that are then applicable to the Company (or if the Company is not then subject to the reporting requirements
of the Exchange Act, then the time periods for filing applicable to a filer that is not an “accelerated filer” as defined
in such rules and regulations):

 

(1)       all
financial information that would be required to be contained in an annual report on Form 10-K, or any successor or comparable form,

reports will not be required to contain a separate financial footnote for Guarantors and Non-Guarantor Subsidiaries contemplated
by Rule 3-10 or Rule 3-16 of Regulation S-X promulgated by the SEC (except summary financial information with respect to Non-Guarantor
Subsidiaries of the type and scope included in the Offering Memorandum will be required).

 

In addition, to the

prospective purchasers of the Notes.

 

    -56-

     

    

 

(b)               
In addition, the Company shall provide Holders, beneficial owners of the Notes, prospective purchasers of the Notes, securities
analysts and market making financial institutions the opportunity to submit written questions to management about the Company’s
business, financial position, results of operations and prospects to the extent the Company affords such an opportunity to investors

(c)               
Delivery to the Trustee of any reports and other information pursuant to this Section 4.03 is for informational purposes
only, and the Trustee’s receipt of such reports and information shall not constitute constructive notice of any information
contained therein or determinable from information contained therein, including the Company’s compliance with any of its
covenants under this Indenture (as to which the trustee is entitled to rely exclusively on Officer’s Certificates). The trustee
shall have no responsibility for the filing, timeliness or content of such reports. The trustee shall further not be obligated

the Issue Date, a certificate from the principal executive officer, principal financial officer or principal accounting officer
stating that a review of the activities of the Company and the Subsidiaries during the preceding fiscal year has been made under
the supervision of the signing Officer with a view to determining whether the Company has kept, observed, performed and fulfilled
its obligations under this Indenture, and further stating, as to 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 condition and covenant contained in this
Indenture and is not in default in the performance or observance of any of the terms, provisions, covenants and conditions of this
Indenture (or, if a Default shall have occurred, describing all such Defaults of which he or she may have knowledge).

 

(b)               
When any Default or Event of Default has occurred and is continuing under this Indenture, or if the Trustee or the holder
of any other evidence of Indebtedness of the Company or any Subsidiary of the Company gives any notice or takes any other action
with respect to a claimed Default or Event of Default, the Company shall promptly (which shall be no more than five Business Days)
upon becoming aware of any Default or Event of Default deliver to the Trustee by registered or certified mail or by electronic
transmission an Officers’ Certificate specifying such event, the status and what action the Company is taking or proposing
to take in respect thereof.

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

 

		Section 4.06	Stay, Extension and Usury
Laws.

 

The Company and
each of the Guarantors covenant (to the extent that they may lawfully do so) that they shall 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 they may lawfully do so) hereby expressly waive all benefit or
advantage of any such law, and covenant that they shall not, by resort to any such law, hinder, delay or impede the execution
of any power herein granted to the Trustee, but shall suffer and permit the execution of every such power as though no such
law has been enacted.

Steel Holding Companies, directly or indirectly, own all of the Capital Stock of the Big River Steel Entities, and indirectly own
all or substantially all of the assets and operations comprising the Big River Steel Business

 

		Section 4.08	Minntac Mining Holding Company.

 

The Company covenants
and agrees that, upon the sale, transfer or other disposition of assets that constitute Collateral to a Minntac Mining Subsidiary,
it shall form a Minntac Mining Holding Company that has no operations or assets other than ownership of the Capital Stock of any

		Section 4.09	Holding Company Indebtedness.

 

Each Big River Steel
Holding Company and Minntac Mining Holding Company will not, and the Company will not permit any Big River Steel Holding Company
or any Minntac Mining Holding Company to, Incur any Indebtedness or any other obligations other than its Note Guarantee of the

to clause (25) of the definition of “Permitted Liens.”

 

		Section 4.10	Asset
                                         Dispositions.

 

(a)       Neither
the Company nor any Guarantor will cause, make or suffer to exist any Asset Disposition of Collateral or any Big River Steel Sale
unless:

 

(1)               
the Company or such Guarantor, as the case may be, receives consideration at least equal to the Fair Market Value (such
Fair Market Value to be determined on the date of contractually agreeing to such Asset Disposition) of the shares and assets subject
to such Asset Disposition;

 

(2)               
except in the case of an Asset Swap, at least 75% of the consideration from such Asset Disposition received by the Company
or such Guarantor, as the case may be, is in the form of cash or Cash Equivalents;

 

(3)               
to the extent that any consideration from such Asset Disposition that is not in the form of cash or Cash Equivalents is
of a type or class that constitutes Collateral then substantially simultaneously with its acquisition it shall be pledged under
the Collateral Documents, with the Lien on such Collateral securing the Notes being of the same priority with respect to the Notes
as the Lien on the assets disposed of; and

 

    -58-

     

    

 

(4)               
the Net Available Cash from any such Asset Disposition is paid directly by the purchaser thereof to the Collateral Agent
to be held in trust in a Collateral Account for application in accordance with this Section 4.10.

 

All of the Net Available
Cash received from a Recovery Event shall be deposited directly into the Collateral Account. Notwithstanding the foregoing provisions,
the Company and the Guarantors will not be required to cause any Net Available Cash to be held in a Collateral Account in accordance
with the preceding sentence and clause (4) above except to the extent the aggregate Net Available Cash from all Asset Dispositions
of Collateral, Big River Steel Sales and Recovery Events that (x) are not held in a Collateral Account and (y) have not been previously
applied in accordance with the provisions of this paragraph (a) exceed $50.0 million.

 

Subject to the terms
of the Intercreditor Agreements, an amount equal to 100% of the Net Available Cash from any Asset Disposition of Collateral, any
Big River Steel Sale or Recovery Event shall (including withdrawing from the Collateral Account), within 365 days from the later
of (i) the date of such Asset Disposition, Big River Steel Sale or Recovery Event and (ii) the date of receipt of such Net Available
Cash, at the Company’s or such Guarantor’s election, (A) be used by the Company or a Guarantor to invest in Additional
Assets (which may include a restoration or replacement (including, without limitation, repairing, rebuilding and reconstructing)
of the affected Collateral in the event of a Recovery Event), which Additional Assets constitute Collateral and that are substantially
simultaneously with their acquisition pledged under the Collateral Documents (or, in the case of real property, subject to a Mortgage
as and when required by Section 11.05), with the Lien on such Collateral securing the Notes being of the same priority with respect
to the Notes as the Lien on the assets disposed of (in the case of an Asset Disposition of Collateral); provided that the
Additional Assets shall not include Capital Stock of Foreign Subsidiaries for purposes of this requirement unless the relevant
Asset Disposition consisted of the Capital Stock of a Foreign Subsidiary or (B) be applied toward a Collateral Disposition Offer
as Excess Collateral Proceeds; provided that in the case of clause (A), a binding commitment to invest in Additional Assets
shall be treated as a permitted application of the Net Available Cash from the date of such commitment so long as the Company or
a Guarantor enters into such commitment with the good faith expectation that such Net Available Cash will be applied to satisfy
such commitment within 180 days of such commitment (an “Acceptable Collateral Commitment”) and such Net Available
Cash is actually applied in such manner within the later of 365 days from the consummation of the Asset Disposition and 180 days
from the date of the Acceptable Collateral Commitment, and in the event any Acceptable Collateral Commitment is later cancelled
or terminated for any reason before the Net Available Cash is applied in connection therewith, the Company or such Subsidiary enters
into another Acceptable Collateral Commitment (a “Second Collateral Commitment”) within 180 days of such cancellation
or termination and such Net Available Cash is actually applied in such manner within 180 days from the date of the Second Collateral
Commitment, it being understood that if a Second Collateral Commitment is later cancelled or terminated for any reason before such
Net Available Cash is applied, then such Net Available Cash shall constitute Excess Collateral Proceeds.

 

    -59-

     

    

 

Any Net Available
Cash from Asset Dispositions of Collateral, Big River Steel Sale or Recovery Events that is not applied or invested as
provided in the preceding paragraph will be deemed to constitute “Excess Collateral Proceeds.” On the
366th day after an Asset Disposition, if the aggregate amount of Excess Collateral Proceeds exceeds $50.0 million, the
Company will be required to make an offer (a “Collateral Disposition Offer”) to all Holders and, to the extent
required by the terms of any outstanding Pari Passu Lien Obligations, to all holders of such Pari Passu Lien Obligations, to
purchase the maximum aggregate principal amount of Notes and any such Pari Passu Lien Obligations that may be purchased out
of the Excess Collateral Proceeds, at an offer price in cash in an amount equal to 100% of the principal amount thereof, plus
accrued and unpaid interest, if any, to the date of purchase (subject to the right of Holders of record on a record date to
receive interest due on the Asset Disposition Purchase Date), in accordance with the procedures set forth in Section 3.09 or
the agreements governing the Pari Passu Lien Obligations, as applicable, in the case of the Notes in integral multiples of
$1,000; provided that if, following repurchase of a portion of a Note, the remaining principal amount of such Note
outstanding immediately after such repurchase would be less than $2,000, then the portion of such Note so repurchased shall
be reduced so that the remaining principal amount of such Note outstanding immediately after such repurchase is $2,000. The
Company shall commence a Collateral Disposition Offer with respect to Excess Collateral Proceeds by mailing (or otherwise
communicating in accordance with the applicable procedures of DTC) the notice required pursuant to Section 3.09, with a copy
to the Trustee. To the extent that the aggregate amount of Notes and Pari Passu Lien Obligations validly tendered and not
properly withdrawn pursuant to a Collateral Disposition Offer is less than the Excess Collateral Proceeds, the Company may
use any remaining Excess Collateral Proceeds for general corporate purposes, subject to other covenants contained in this
Indenture and the Collateral Documents. If the aggregate principal amount of Notes and other Pari Passu Lien Obligations
validly tendered and not properly withdrawn pursuant to a Collateral Disposition Offer exceeds the amount of Excess
Collateral Proceeds, the Trustee shall select the Notes and such Pari Passu Lien Obligations to be purchased on a pro rata
basis on the basis of the aggregate accreted value or principal amount of tendered Notes and Pari Passu Lien Obligations
(provided that the selection of such Pari Passu Lien Obligations shall be made pursuant to the terms of such Pari
Passu Lien Obligations). Upon completion of such Collateral Disposition Offer, the amount of Excess Collateral Proceeds shall
be reset at zero. Pending the final application of any such Net Available Cash (other than Net Available Cash required to be
held in a Collateral Account), in accordance with clauses (A) or (B) of the third paragraph of this Section 4.10(a), the
Company and the Guarantors may temporarily reduce Indebtedness (including under a revolving Debt Facility) or otherwise
invest such Net Available Cash in any manner not prohibited by this Indenture or the Collateral Documents.

 

(b)               
The Company will not, and will not permit any of its Subsidiaries to, cause, make or suffer to exist any Asset Disposition
(other than an Asset Disposition of Collateral or any Big River Steel Sale, which shall each be treated in the manner set forth
in paragraph (a) above) unless:

 

(1)               
the Company or such Subsidiary, as the case may be, receives consideration at least equal to the Fair Market Value (such
Fair Market Value to be determined on the date of contractually agreeing to such Asset Disposition) of the shares and assets subject
to such Asset Disposition; and

 

(2)               
except in the case of an Asset Swap, at least 75% of the consideration from such Asset Disposition received by the Company
or such Subsidiary, as the case may be, is in the form of cash or Cash Equivalents.

 

Within 365 days from
the later of the date of such Asset Disposition or the receipt of such Net Available Cash, an amount equal to 100% of the Net Available
Cash from such Asset Disposition may be applied by the Company or such Subsidiary, as the case may be, as follows:

 

(A)             
to permanently reduce (and permanently reduce commitments with respect thereto) Obligations under the ABL Facility;

 

(B)             
to permanently reduce obligations under other Indebtedness of the Company (other than any Disqualified Stock or Subordinated
Obligations) or Indebtedness of a Guarantor (other than any Disqualified Stock or Guarantor Subordinated Obligations), in each
case other than Indebtedness owed to the Company or an Affiliate of the Company;

 

    -60-

     

    

 

(C)             
in the case of an Asset Disposition by a Non-Guarantor Subsidiary, to permanently reduce obligations under Indebtedness
of any Non-Guarantor Subsidiary, other than Indebtedness owed to the Company or an Affiliate of the Company;

 

(D)             
to invest in Additional Assets; provided that, to the extent such Additional Assets are of the type that would constitute
Collateral under the Collateral Documents, such Additional Assets are concurrently added to the Collateral securing the Notes and
the Note Guarantees in the manner and to the extent required in this Indenture or any of the Collateral Documents; or

 

(E)              
any combination of the foregoing;

 

provided
that pending the final application of any such Net Available Cash in accordance with clause (A), (B), (C), (D) or (E) above, the
Company and its Subsidiaries may temporarily reduce Indebtedness (including under a revolving Debt Facility) or otherwise invest
such Net Available Cash in any manner not prohibited by this Indenture; provided, further, that in the case of clause
(D), a binding commitment to invest in Additional Assets shall be treated as a permitted application of the Net Available Cash
from the date of such commitment so long as the Company or a Subsidiary enters into such commitment with the good faith expectation
that such Net Available Cash will be applied to satisfy such commitment within 180 days of such commitment (an “Acceptable
Commitment”) and such Net Available Cash is actually applied in such manner within the later of 365 days from the consummation
of the Asset Disposition and 180 days from the date of the Acceptable Commitment, and in the event any Acceptable Commitment is
later cancelled or terminated for any reason before the Net Available Cash is applied in connection therewith, the Company or such
Subsidiary enters into another Acceptable Commitment (a “Second Commitment”) within 180 days of such cancellation
or termination and such Net Available Cash is actually applied in such manner within 180 days from the date of the Second Commitment,
it being understood that if a Second Commitment is later cancelled or terminated for any reason before such Net Available Cash
is applied, then such Net Available Cash shall constitute Excess Proceeds. Notwithstanding the foregoing, any Big River Steel Excess
Proceeds shall be applied by the Company and its Subsidiaries in accordance with the provisions set forth in paragraph (a) above.

 

Any Net Available
Cash from Asset Dispositions under this clause (b) that is not applied or invested as provided in the preceding paragraph
will be deemed to constitute “Excess Proceeds.” On the 366th day after an Asset Disposition, if the
aggregate amount of Excess Proceeds exceeds $50.0 million, the Company will be required to make an offer (an “Asset
Disposition Offer”) to all Holders and, to the extent required by the terms of any outstanding Pari Passu Indebtedness,
to all holders of such Pari Passu Indebtedness, to purchase the maximum aggregate principal amount of Notes and any such Pari
Passu Indebtedness that may be purchased out of the Excess Proceeds, at an offer price in cash in an amount equal to 100% of
the principal amount thereof, plus accrued and unpaid interest, if any, to the date of purchase (subject to the right of
Holders of record on a record date to receive interest due on the Asset Disposition Purchase Date, in accordance with the
procedures set forth in Section 3.09 or the agreements governing the Pari Passu Indebtedness, as applicable, in the case of
the Notes in integral multiples of $1,000; provided that if, following repurchase of a portion of a Note, the
remaining principal amount of such Note outstanding immediately after such repurchase would be less than $2,000, then the
portion of such Note so repurchased shall be reduced so that the remaining principal amount of such Note outstanding
immediately after such repurchase is $2,000. The Company shall commence an Asset Disposition Offer with respect to Excess
Proceeds by mailing (or otherwise communicating in accordance with the applicable procedures of DTC) the notice required
pursuant to Section 3.09, with a copy to the Trustee. To the extent that the aggregate amount of Notes and Pari Passu
Indebtedness validly tendered and not properly withdrawn pursuant to an Asset Disposition Offer is less than the Excess
Proceeds, the Company may use any remaining Excess Proceeds for general corporate purposes, subject to other covenants
contained in this Indenture. If the aggregate principal amount of Notes and Pari Passu Indebtedness validly tendered and not
properly withdrawn pursuant to an Asset Disposition Offer exceeds the amount of Excess Proceeds, the Trustee shall select the
Notes and such Pari Passu Indebtedness to be purchased on a pro rata basis on the basis of the aggregate accreted value or
principal amount of tendered Notes and Pari Passu Indebtedness (provided that the selection of such Pari Passu
Indebtedness shall be made pursuant to the terms of such Pari Passu Indebtedness). Upon completion of such Asset Disposition
Offer, the amount of Excess Proceeds shall be reset at zero.

 

    -61-

     

    

 

 

(c)               
The Company will not, and will not permit any Subsidiary to, engage in any Asset Swaps, unless:

 

(1)               
at the time of entering into such Asset Swap and immediately after giving effect to such Asset Swap, no Default or
Event of Default shall have occurred and be continuing or would occur as a consequence thereof;

 

(2)               
in the event such Asset Swap involves the transfer by the Company or any Subsidiary of assets having an aggregate
Fair Market Value, as determined by the Board of Directors of the Company in good faith, in excess of $50.0 million, the terms
of such Asset Swap have been approved by a majority of the disinterested members of the Board of Directors of the Company; and

 

(3)                in
the event such Asset Swap involves the transfer by the Company or any Subsidiary of assets having an aggregate Fair Market Value,
as determined by the Board of Directors of the Company in good faith, in excess of $75.0 million, the Company has received a written
opinion from an Independent Financial Advisor that such Asset Swap is fair to the Company or such Subsidiary, as the case may be,
from a financial point of view.

 

(d)               
For the purposes of Section 4.10(a)(2) and Section 4.10(b)(2) and for no other purpose, the following will be deemed to
be cash:

 

(1)               
any liabilities (as shown on the Company’s or such Subsidiary’s most recent balance sheet) of the Company
or any Subsidiary (other than (x) for purposes of clause (a)(2) of this Section 4.10, liabilities that are by their terms subordinated
to the Notes or the Note Guarantees or are Junior Lien Obligations or Senior Unsecured Pari Passu Indebtedness and (y) for purposes
of clause (b)(2) of this Section 4.10, liabilities that are by their terms subordinated to the Notes or the Note Guarantees) that
are assumed by the transferee of any such assets and from which the Company and all Subsidiaries have been validly released by
all creditors in writing;

 

(2)               
any securities, notes or other obligations received by the Company or any Subsidiary from the transferee that are
converted by the Company or such Subsidiary into cash (to the extent of the cash received) within 180 days following the closing
of such Asset Disposition; and

 

(3)                any
Designated Noncash Consideration received by the Company or any of its Subsidiaries in such Asset Disposition having an
aggregate Fair Market Value, taken together with all other Designated Noncash Consideration received pursuant to this clause

other Guarantor in respect of the Obligations of such other Guarantor under its Note Guarantee or pursuant to its contribution
Obligations under this Indenture, result in the Obligations of such Guarantor under its Note Guarantee not constituting a fraudulent
conveyance or fraudulent transfer under federal or state law.

security interest (subject to Permitted Liens) in properties and assets that constitute Collateral as security for such Guarantor’s
Note Guarantee and as may be necessary to have such property or asset added to the Collateral as required under the Collateral
Documents, the Collateral Cooperation Agreement and this Indenture, and thereupon all provisions of this Indenture relating to
the Collateral shall be deemed to relate to such properties and assets to the same extent and with the same force and effect.

regard to any property upon which a security interest must be perfected, such security interests and Liens shall be created under
the Collateral Documents in form satisfactory to the Notes Collateral Agent, and the Company and the Guarantors shall deliver

to be maintained and kept in good condition, repair and working order (reasonable wear and tear excepted) and shall cause to be
made all necessary renewals and replacements thereof except where the failure to do so could not reasonably be expected to have

desirable in the conduct of the business of such entity and (ii) would not have a material adverse effect on the ability of the
Company or the Guarantors to satisfy their obligations under the Notes, the Note Guarantees and this Indenture, and, to the extent

in the acceleration of such Indebtedness prior to its maturity,

 

and, in each
case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which
there has been a payment default or the maturity of which has been so accelerated, aggregates $100.0 million or more;

 

(7)              failure
by the Company or any Significant Subsidiary or any group of Subsidiaries that, taken together (as of the date of the latest
audited consolidated financial statements of the Company and its Subsidiaries), would constitute a Significant Subsidiary to
pay final judgments aggregating in excess of $100.0 million (net of any amounts that a reputable and creditworthy insurance
company has acknowledged liability for in writing), which judgments are not paid, discharged or stayed for a period of 60
days or more after such judgment becomes final;

(8)              the Company or a Significant Subsidiary or any group of Subsidiaries that, taken together (as of the date of the latest
audited consolidated financial statements of the Company and its Subsidiaries), would constitute a Significant Subsidiary pursuant
to or within the meaning of any Bankruptcy Law:

 

(i)         commences
proceedings to be adjudicated bankrupt or insolvent;

 

(ii)        consents
to the institution of bankruptcy or insolvency proceedings against it, or the filing by it of a petition or answer or consent seeking

(iii)       consents
to the appointment of a receiver, liquidator, assignee, trustee, sequestrator or other similar official of it or for all or substantially
all of its property;

 

(iv)       makes

(v)        generally
is not paying its debts as they become due;

 

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

 

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

 

(ii)         appoints
a receiver, liquidator, assignee, trustee, sequestrator or other similar official of the Company or a Significant Subsidiary or

(10)           
any Note Guarantee of a Significant Subsidiary or any group of Guarantors that, taken together (as of the date of the latest
audited consolidated financial statements of the Company and its Subsidiaries), would constitute a Significant Subsidiary, Collateral
Document or obligation under the Collateral Cooperation Agreement or any Intercreditor Agreement ceases to be in full force and
effect (except as contemplated by the terms of this Indenture, such Collateral Document, the Collateral Cooperation Agreement or
such Intercreditor Agreement) or is declared null and void in a judicial proceeding or any Guarantor that is a Significant Subsidiary
or any group of Guarantors that, taken together (as of the date of the latest audited consolidated financial statements of the
Company and its Subsidiaries), would constitute a Significant Subsidiary denies or disaffirms its obligations under this Indenture,

full force and effect for any reason other than in accordance with their terms and the terms of this Indenture, the Collateral
Cooperation Agreement and the Intercreditor Agreements, which failure continues for 60 days or (B) the assertion by the Company
or any Guarantor, in any pleading in any court of competent jurisdiction, that any such security interest is invalid or unenforceable.

 

However, a default under
clauses (4) and (5) of this Section 6.01(a) will not constitute an Event of Default until the Trustee or the Holders of at least
25% in principal amount of the then outstanding Notes notify the Company of the default and the Company does not cure such default
within the time specified in clauses (4) and (5) of this Section 6.01(a) after receipt of such notice.

 

(b)               
In the event of a declaration of acceleration of the Notes because an Event of Default described in clause (6) of Section
6.01(a) has occurred and is continuing, the declaration of acceleration of the Notes shall be automatically annulled if:

 

(1)       the
default triggering such Event of Default pursuant to clause (6) of Section 6.01(a) shall be remedied or cured by the Company or
a Subsidiary or waived by the holders of the relevant Indebtedness within 20 days after the declaration of acceleration with respect
thereto; and

 

(2)       (A)
the annulment of the acceleration of the Notes would not conflict with any judgment or decree of a court of competent jurisdiction
and (B) all existing Events of Default, except nonpayment of principal, premium, if any, or interest on the Notes that became due
solely because of the acceleration of the Notes, have been cured or waived.

 

 Section 6.02            Acceleration.

 

If any Event of
Default (other than an Event of Default specified in clause (8) or (9) of Section 6.01(a)) occurs and is continuing under
this Indenture, the Trustee by written notice to the Company, specifying the Event of Default, or the Holders of at least 25%
in principal amount of the then total outstanding Notes by notice to the Company and the Trustee may, and the Trustee at the
request of such Holders shall, declare the principal of, premium, if any, accrued and unpaid interest and any other monetary
obligations on all the then outstanding Notes to be due and payable immediately. Upon the effectiveness of such declaration,
such principal and interest shall be due and payable immediately.

 

    -73-

     

    

 

Notwithstanding the foregoing,
in the case of an Event of Default arising under clause (8) or (9) of Section 6.01(a), all outstanding Notes shall be due and payable
immediately without further action or notice.

 

The Holders of a majority
in principal amount of the outstanding Notes may waive all past defaults (except with respect to nonpayment of principal, premium
or interest) and rescind any such acceleration with respect to the Notes and its consequences if (1) such rescission would not
conflict with any judgment or decree of a court of competent jurisdiction and (2) all existing Events of Default, other than the
nonpayment of the principal of, premium, if any, and interest on the Notes that have become due solely by such declaration of acceleration,
have been cured or waived.

 

If the Notes are accelerated
or otherwise become due prior to their stated maturity, in each case as a result of an Event of Default (including, but not limited
to, an Event of Default specified in Section 6.01(a)(8) or Section 6.01(a)(9) (including the acceleration of any portion of the
Indebtedness evidenced by the Notes by operation of law)), the amount that shall then be due and payable shall be equal to:

 

		(x)	(i) 100% of the principal amount of the Notes then outstanding plus the Applicable Premium in effect
on the date of such acceleration or (ii) the applicable redemption price in effect on the date of such acceleration, as applicable,
plus

 

		(y)	accrued and unpaid interest to, but excluding, the date of such acceleration, in each case as if
such acceleration were an optional redemption of the Notes so accelerated.

 

Without limiting
the generality of the foregoing, it is understood and agreed that if the Notes are accelerated or otherwise become due prior
to their stated maturity, in each case, as a result of an Event of Default (including, but not limited to, an Event of
Default specified in Section 6.01(a)(8) or Section 6.01(a)(9) (including the acceleration of any portion of the Indebtedness
evidenced by the Notes by operation of law)), the Applicable Premium or the amount by which the applicable redemption price
exceeds the principal amount of the Notes (the “Redemption Price Premium”), as applicable, with respect to
an optional redemption of the Notes shall also be due and payable as though the Notes had been optionally redeemed on the
date of such acceleration and shall constitute part of the Obligations with respect to the Notes in view of the
impracticability and difficulty of ascertaining actual damages and by mutual agreement of the parties as to a reasonable
calculation of each Holder’s lost profits as a result thereof. If the Applicable Premium or the Redemption Price
Premium, as applicable, becomes due and payable, it shall be deemed to be principal of the Notes and interest shall accrue on
the full principal amount of the Notes (including the Applicable Premium or the Redemption Price Premium, as applicable) from
and after the applicable triggering event, including in connection with an Event of Default specified in Section 6.01(a)(8)
or Section 6.01(a)(9). Any premium payable pursuant to this paragraph shall be presumed to be liquidated damages sustained by
each Holder as the result of the acceleration of the Notes and the Company agrees that it is reasonable under the
circumstances currently existing. The premium shall also be payable in the event the Notes or this Indenture are satisfied,
released or discharged through foreclosure, whether by judicial proceeding, deed in lieu of foreclosure or by any other
means. THE COMPANY AND EACH GUARANTOR EXPRESSLY WAIVES (TO THE FULLEST EXTENT THEY MAY LAWFULLY DO SO) THE PROVISIONS OF ANY
PRESENT OR FUTURE STATUTE OR LAW THAT PROHIBITS OR MAY PROHIBIT THE COLLECTION OF THE FOREGOING PREMIUM IN CONNECTION WITH
ANY SUCH ACCELERATION. The Company and each Guarantor expressly agrees (to the fullest extent it may lawfully do so) that:
(A) the premium is reasonable and is the product of an arm’s length transaction between sophisticated business entities
ably represented by counsel; (B) the premium shall be payable notwithstanding the then prevailing market rates at the time
acceleration occurs; (C) there has been a course of conduct between the Holders and the Company giving specific consideration
in this transaction for such agreement to pay the premium; and (D) the Company each Guarantor shall be estopped hereafter
from claiming differently than as agreed to in this paragraph. The Company and each Guarantor expressly acknowledges that its
agreement to pay the premium to the Holders as herein described is a material inducement to the Holders to purchase the
Notes.

 Section 6.03            Other Remedies.

 

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

 

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

 

 Section 6.04            Waiver of Past Defaults.

 

Holders of not less than
a majority in aggregate principal amount of the then outstanding Notes by written notice to the Trustee may on behalf of the Holders
of all of the Notes waive any existing Default and its consequences hereunder, except (1) a continuing Default in the payment of
the principal of, premium, if any, or interest on, any Note held by a non-consenting Holder (including in connection with an Asset
Disposition Offer or a Change of Control Offer) and (2) a Default with respect to a provision that under Section 9.02 cannot be
amended without the consent of each Holder affected; provided, subject to Section 6.02, 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.

 

The Holders of a majority
in principal amount of the outstanding Notes may direct the time, method and place of conducting any proceeding for any remedy
available to the Trustee or the Collateral Agent of exercising any trust or power conferred on the Trustee or the Collateral Agent.
The Trustee and the Collateral Agent, as the case may be, however, may refuse to follow any direction that conflicts with law,
this Indenture, the Notes, any Note Guarantee, the Collateral Documents, the Collateral Cooperation Agreement or the Intercreditor
Agreements, or that is unduly prejudicial to the rights of any other Holder or that would involve the Trustee or the Collateral
Agent in personal liability (it being understood that neither the Trustee nor the Notes Collateral Agent shall be responsible for
determining if any action is prejudicial to the Holders or any Holder).

 

    -75-

     

    

 

 Section 6.06            Limitation on Suits.

 

Subject to Section 6.07,
no Holder of a Note may pursue any remedy with respect to this Indenture or the Notes unless:

 

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

 

(2)               Holders of at least 25% in principal amount of the total outstanding Notes have requested the Trustee to pursue the remedy;

 

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

 

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

 

(5)               
the Holders of a majority in principal amount of the then outstanding Notes have not given the Trustee a direction that,
in the opinion of the Trustee, is inconsistent with such request within such 60-day period.

 

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 contractual right expressly set forth in this Indenture or the Notes of any Holder of a Note to
bring suit for the enforcement of any payment on or with respect to such Holder’s Notes shall not be amended without the
consent of such Holder.

 

 Section 6.08            Collection Suit by Trustee.

 

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

 

 Section 6.09            Restoration of Rights and Remedies.

 

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

 

    -76-

     

    

 

 Section 6.10            Rights and Remedies Cumulative.

 

Except as otherwise provided
with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes in Section 2.07, no right or remedy herein
conferred upon or reserved to the Trustee, the Notes Collateral Agent or to the Holders is intended to be exclusive of any other
right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other
right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of
any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate
right or remedy.

 

 Section 6.11            Delay or Omission Not Waiver.

 

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

 

 Section 6.12            Trustee May File Proofs of Claim.

 

The Trustee is authorized
to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the
Trustee and the Notes Collateral Agent (including any claim for the reasonable compensation, expenses, disbursements and advances
of the Trustee, the Notes Collateral Agent and their respective agents and counsel) and the Holders of the Notes allowed in any
judicial proceedings relative to the Company (or any other obligor upon the Notes including the Guarantors), its creditors or its
property and shall be entitled and empowered to participate as a member in any official committee of creditors appointed in such
matter and to collect, receive and distribute any money or other property payable or deliverable on any such claims and any custodian
in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the event that
the Trustee and the Notes Collateral Agent shall consent to the making of such payments directly to the Holders, to pay to the
Trustee and the Notes Collateral Agent any amount due to them for the reasonable compensation, expenses, disbursements and advances
of the Trustee, the Notes Collateral Agent and their respective agents and counsel, and any other amounts due the Trustee and the
Notes Collateral Agent hereunder. To the extent that the payment of any such compensation, expenses, disbursements and advances
of the Trustee, the Notes Collateral Agent, their agents and counsel, and any other amounts due the Trustee and the Notes Collateral
Agent hereunder 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 and the Notes 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 and the Notes Collateral Agent to vote in respect of the claim of any
Holder in any such proceeding.

 

 Section 6.13            Priorities.

 

Subject to the
terms of the Collateral Documents, the Collateral Cooperation Agreement and the Intercreditor Agreements with respect to any
proceeds of Collateral, any money or property collected by the Trustee or the Notes Collateral Agent pursuant to this Article
6 and any money or other property distributable in respect of any Grantor’s Obligations under this Indenture after an
Event of Default shall be applied in the following order:

 

    -77-

     

    

 

FIRST: to
pay Obligations then due to the Trustee, the Notes Collateral Agent or any Agent (including fees and expenses of their agents and
counsel) pursuant to this Indenture and the other Notes Documents;

 

SECOND: to
pay Obligations in respect of any reasonable expense reimbursements or indemnities then due to the Holders (or holders of Pari
Passu Lien Obligations (if any));

 

THIRD: to
pay interest then due and payable in respect of the Notes;

 

FOURTH: to
pay or prepay principal payments in respect of the Notes; and

 

FIFTH: to
pay all other Obligations with respect to the Notes, the Guarantees and this Indenture;

 

SIXTH: to
the Company or such other persons who shall be entitled thereto;

 

provided, however, that if
sufficient funds are not available to fund all payments required to be made in any of clauses FIRST through FIFTH above, the available
funds being applied to the Obligations specified in any such clause (unless otherwise specified in such clause) shall be allocated
to the payment of such Obligations ratably, based on the proportion of the relevant party’s interest in the aggregate outstanding
Obligations described in such clause.

 

The Trustee may fix a
record date and payment date for any payment to Holders of Notes pursuant to this Section 6.13.

 

 Section 6.14            Undertaking for Costs.

 

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

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

 

    -78-

     

    

 

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

 

(i)             
the duties of the Trustee shall 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)             in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness
of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of
this Indenture. However, 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 shall 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 mathematical calculations or other facts
stated therein).

 

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

 

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

 

(ii)             
the Trustee shall 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 that the Trustee was negligent in ascertaining the pertinent facts;

 

(iii)           
the Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a
direction received by it pursuant to Section 6.05; and

 

(iv)           
no provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise to incur any liability,
financial or otherwise, in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers if
it shall have reasonable grounds for believing that repayment of such funds or indemnity satisfactory to it against such risk or
liability is not assured to it.

 

(d)              
Whether or not therein expressly so provided, every provision of this Indenture that in any way relates to the Trustee is
subject to paragraphs (a), (b) and (c) of this Section 7.01.

 

(e)

direction of any of the Holders of the Notes unless the Holders have (a) offered to the Trustee indemnity or security satisfactory
to the Trustee against any loss, liability or expense in relation to such exercise and (b) otherwise complied with the terms of
this Indenture, including, but not limited to, providing proof of holdings satisfactory to the Trustee.

The Trustee shall not be liable for interest on any money received by it except as the Trustee may agree in writing with
the Company. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law.

 Section 7.02            Rights of Trustee.

 

(a)                The
Trustee may conclusively rely upon any document believed by it to be genuine and to have been signed or presented by the
proper Person. The Trustee need not investigate any fact or matter stated in any resolution, certificate, statement,
instrument, opinion, report, notice, request, direction, consent, order or any other paper or document, or inquire as to the
performance by the Company or any Guarantor of any of their covenants in this Indenture. Notwithstanding the foregoing, the
Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and,
if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books,
records and premises of the Company, personally or by agent or attorney at the sole cost of the Company and shall incur no
liability or additional liability of any kind by reason of such inquiry or investigation.

 

(b)                Before the Trustee acts or refrains from acting, it may require an Officers’ Certificate or an Opinion of Counsel
or both. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on such Officers’
Certificate or Opinion of Counsel. The Trustee may consult with counsel of its selection and the advice of such counsel or any
Opinion of Counsel, at the Company’s expense, shall 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.

The Trustee may act through its attorneys and agents, at the Company’s expense, and shall not be responsible for the
misconduct or negligence of any agent or attorney appointed with due care.

 

(d)              
The Trustee shall not be liable for any action it takes or omits to take in good faith that it believes to be authorized
or within the rights or powers conferred upon it by this Indenture.

 

(e)              
Unless otherwise specifically provided in this Indenture, any demand, request, direction or notice from the Company shall
be sufficient if signed by an Officer of the Company.

 

(f)                
The Trustee shall not be deemed to have notice of any Default or Event of Default unless a Responsible Officer of the Trustee
has actual knowledge thereof or unless written notice of any Default or Event of Default is received by a Responsible Officer of
the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Notes, this Indenture and that a Default
or Event of Default has occurred. Delivery of reports to the Trustee pursuant to Section 4.03 shall not constitute actual knowledge
of, or notice to, the Trustee of the information contained therein.

 

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

 

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

The Trustee shall not be required to give any bond or surety in respect of the performance of its powers and duties hereunder.

The Trustee may request that the Company and any Guarantor deliver an Officers’ Certificate setting forth the names
of the individuals and/or titles of Officers (with specimen signatures) authorized at such times to take specific actions pursuant
to this Indenture, which Officers’ Certificate may be signed by any person specified as so authorized in any certificate
previously delivered and not superseded.

 

(k)              
Any permissive right of the Trustee to take or refrain from taking any actions enumerated in this Indenture or any other
Notes Document shall not be construed as a duty.

 Section 7.03            Individual Rights of Trustee.

 

The Trustee in its individual
or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the 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 it must eliminate such conflict within 90 days or resign. Any Agent may do the same with like rights and duties. The Trustee
is also subject to Section 7.09.

 

 Section 7.04            Trustee’s Disclaimer.

 

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

 

 Section 7.05            Notice of Defaults.

 

If a Default occurs and
is continuing and if it is known to the Trustee, the Trustee shall mail or otherwise deliver in accordance with the procedures
of DTC to Holders of Notes a notice of the Default within 90 days after it is known to the Trustee, unless such default shall have
been cured or waived. Except in the case of a Default relating to the payment of principal, premium, if any, or interest on any
Note, the Trustee may withhold from the Holders notice of any continuing Default if and for so long as the Trustee in good faith
determines that withholding the notice is in the interests of the Holders of the Notes. In addition, the Trustee shall have no
obligation to accelerate the Notes if in the judgment of the Trustee acceleration is not in the interest of the Holders of the
Notes.

 

 Section 7.06            Compensation and Indemnity.

 

The Company shall pay
to the Trustee and the Notes Collateral Agent from time to time such compensation for its acceptance of this Indenture and services
provided hereunder as Trustee and Agent, and as Notes Collateral Agent hereunder and under the Collateral Documents, the Collateral
Cooperation Agreement and the Intercreditor Agreements as the parties shall agree in writing from time to time. The Trustee’s
and the Notes Collateral Agent’s compensation shall not be limited by any law on compensation of a trustee of an express
trust. The Company shall reimburse the Trustee and the Notes Collateral Agent promptly upon request for all reasonable disbursements,
advances and out-of-pocket expenses incurred or made by them in addition to the compensation for their services. Such expenses
shall include the reasonable compensation, disbursements and out-of-pocket expenses of the Trustee’s and the Notes Collateral
Agent’s agents and counsel.

 

    -81-

     

    

 

 

The Company and the
Guarantors, jointly and severally, shall indemnify the Trustee and the Notes Collateral Agent for, and hold the Trustee and
the Notes Collateral Agent harmless against, any and all loss, damage, claim, liability or expense (including
attorneys’ fees) incurred by it in connection with the acceptance or administration of this trust and the performance
of its duties hereunder, under the Collateral Documents, the Collateral Cooperation Agreement and the Intercreditor
Agreements (including the costs and expenses of enforcing this Indenture and the other Notes Documents against the Company or
any of the Guarantors (including this Section 7.06) or defending itself against any claim whether asserted by any Holder, any
holder of other Pari Passu Lien Obligations (if any), the Company or any Guarantor, or liability in connection with the
acceptance, exercise or performance of any of its powers or duties hereunder or under the other Notes Documents). The Trustee
or the Notes Collateral Agent shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the
Trustee or the Notes Collateral Agent to so notify the Company shall not relieve the Company of its obligations hereunder.
The Company and the Guarantors shall defend the claim and the Trustee and the Notes Collateral Agent may have separate
counsel and the Company shall pay the reasonable fees and expenses of such counsel. The Company need not reimburse any
expense or indemnify against any loss, liability or expense incurred by the Trustee or the Notes Collateral Agent through the
Trustee’s or the Notes Collateral Agent’s own willful misconduct or gross negligence, as determined pursuant to a
final and non-appealable judgment of a court of competent jurisdiction.

 

The obligations of the
Company and the Guarantors under this Article 7 shall survive the satisfaction and discharge of this Indenture or the earlier resignation
or removal of the Trustee or the Notes Collateral Agent, as applicable.

 

To secure the payment
obligations of the Company and the Guarantors in this Section 7.06, the Trustee and the Notes Collateral Agent shall have a Lien
prior to the Notes and rights of the Holders (and holders of Other Pari Passu Lien Obligations (if any)) on all money or property
held or collected by the Trustee or the Notes Collateral Agent, except that held in trust to pay principal and interest on particular
Notes. Such Lien shall survive the satisfaction and discharge of this Indenture.

 

When the Trustee or the
Notes Collateral Agent incurs expenses or renders services upon and after an Event of Default specified in Section 6.01(a)(7) or
(8) occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are
intended to constitute administrative expenses with priority pursuant to any Bankruptcy Law.

 

 Section 7.07            Replacement of Trustee.

 

A resignation or removal
of the Trustee and appointment of a successor Trustee shall become effective only upon the successor Trustee’s acceptance
of appointment as provided in this Section 7.07. 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 principal amount of the then outstanding Notes may remove
the Trustee by so notifying the Trustee and the Company in writing. The Company may remove the Trustee if:

 

(a)                
the Trustee fails to satisfy the eligibility requirements set forth in Section 7.09;

 

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

 

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

 

(d)               
the Trustee becomes incapable of acting.

 

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

 

    -82-

     

    

 

If a successor Trustee
does not take office within 30 days after the retiring Trustee resigns or is removed, the retiring Trustee (at the Company’s
expense), the Company or the Holders of at least 10% in principal amount of the then outstanding Notes may petition any court of
competent jurisdiction for the appointment of a successor Trustee.

 

If the Trustee, after
written request by any Holder who has been a Holder for at least six months, fails to comply with Section 7.09, such Holder may
petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

 

A successor Trustee shall
deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon, the resignation or removal
of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee
under this Indenture. The successor Trustee shall mail a notice of its succession to Holders. The retiring Trustee shall 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 7.06. Notwithstanding replacement of the Trustee pursuant to this Section
7.07, the Company’s obligations under Section 7.06 shall continue for the benefit of the retiring Trustee.

 

 Section 7.08            Successor Trustee by Merger, Etc.

 

If the Trustee or the
Notes Collateral Agent 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 shall be the successor Trustee or Notes Collateral Agent.

 

 Section 7.09            Eligibility; Disqualification.

 

There shall 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 $50,000,000 as set forth in its most recent
published annual report of condition.

 

 Section 7.10            Collateral Documents; Collateral Cooperation Agreement; Intercreditor Agreements.

 

By their acceptance of
the Notes, the Holders hereby authorize and direct the Trustee and Notes Collateral Agent, as the case may be, to execute and deliver
the Collateral Cooperation Agreement, the Intercreditor Agreements and the Collateral Documents in which the Trustee or the Notes
Collateral Agent, as applicable, is named as a party, including the Pari Passu Intercreditor Agreement or any Collateral Documents,
in each case, executed after the Issue Date. It is hereby expressly acknowledged and agreed that, in doing so, the Trustee and
the Notes Collateral Agent are not responsible for the terms or contents of such agreements, or for the validity or enforceability
thereof, or the sufficiency thereof for any purpose. Whether or not so expressly stated therein, in entering into, or taking (or
forbearing from) any action under pursuant to, the Collateral Cooperation Agreement, the Intercreditor Agreements or any other
Collateral Documents, the Trustee and the Notes Collateral Agent each shall have all of the rights, immunities, indemnities and
other protections granted to it under this Indenture (in addition to those that may be granted to it under the terms of such other
agreement or agreements).

 

Neither the Trustee
nor the Notes Collateral Agent shall have any obligation whatsoever to assure that the Collateral exists or is owned by the
Company or any Guarantor or is cared for, protected, or insured or has been encumbered, or that the Notes Collateral
Agent’s Liens have been properly or sufficiently or lawfully created, perfected, protected, maintained or enforced or
are entitled to any particular priority, or to determine whether all or the Company’s or Guarantor’s property
constituting collateral intended to be subject to the Lien and security interest of the Collateral Documents has been
properly and completely listed or delivered, as the case may be, or the genuineness, validity, marketability or sufficiency
thereof or title thereto, or to exercise at all or in any particular manner or under any duty of care, disclosure, or
fidelity, or to continue exercising, any of the rights, authorities, and powers granted or available to the Notes Collateral
Agent pursuant to this Indenture, any Collateral Document, the Collateral Cooperation Agreement or the Intercreditor
Agreements other than pursuant to the instructions of the Holders of a majority in aggregate principal amount of the Notes,
it being understood and agreed that in respect of the Collateral, or any act, omission, or event related thereto, neither the
Trustee nor the Notes Collateral Agent shall have any duty or liability whatsoever to any Noteholder Secured Party as to any
of the foregoing.

ARTICLE 8

LEGAL DEFEASANCE AND COVENANT DEFEASANCE

 

 Section 8.01            Option to Effect Legal Defeasance and Covenant Defeasance.

 

The Company may, at its
option and at any time, elect to have either Section 8.02 or 8.03 applied to all outstanding Notes upon compliance with the conditions
set forth below in this Article 8.

 

 Section 8.02            Legal Defeasance and Discharge.

 

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

 

(i)             
the rights of Holders of Notes to receive payments in respect of the principal of, premium, if any, and interest on the
Notes when such payments are due solely out of the trust created pursuant to this Indenture referred to in Section 8.04;

 

(ii)             
the Company’s obligations with respect to the Notes concerning issuing temporary Notes, registration of such Notes,
mutilated, destroyed, lost or stolen Notes and the maintenance of an office or agency for payment and money for security payments
held in trust;

 

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

 

(iv)             
this Section 8.02.

 

    -84-

     

    

 

(b)               
Following the Company’s exercise of its Legal Defeasance option, payment of the Notes may not be accelerated because
of an Event of Default.

 

(c)               
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.

 

 Section 8.03            Covenant Defeasance.

 

Upon the Company’s
exercise under Section 8.01 of the option applicable to this Section 8.03, the Company and the Guarantors shall, subject to the
satisfaction of the conditions set forth in Section 8.04, be released from their obligations under the covenants contained in Sections
3.09, 4.03, 4.05, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.14, 4.15, 4.17 and 4.18 with respect to the outstanding Notes, and
the Guarantors shall be deemed to have been discharged from their obligations with respect to all Note Guarantees, on and after
the date the conditions set forth in Section 8.04 are satisfied (“Covenant Defeasance”), and the Notes shall
thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of
Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed “outstanding”
for all other purposes hereunder (it being understood that such Notes shall not be deemed outstanding for accounting purposes).
For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes, the Company may omit to comply with and
shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly,
by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other
provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under
Section 6.01, but, except as specified above, the remainder of this Indenture and such Notes shall be unaffected thereby. In addition,
upon the Company’s exercise under Section 8.01 of the option applicable to this Section 8.03, subject to the satisfaction
of the conditions set forth in Section 8.04, Sections 6.01(a)(4) (only with respect to covenants that are released as a result
of such Covenant Defeasance), 6.01(a)(5) (only with respect to covenants that are released as a result of such Covenant Defeasance),
6.01(a)(6), 6.01(a)(7), 6.01(a)(8) (solely with respect to Significant Subsidiaries or any group of Subsidiaries that, taken together
(as of the date of the latest audited consolidated financial statements of the Company and its Subsidiaries) would constitute a
Significant Subsidiary), 6.01(a)(9) (solely with respect to Significant Subsidiaries or any group of Subsidiaries that, taken together
(as of the date of the latest audited consolidated financial statements of the Company and its Subsidiaries) would constitute a
Significant Subsidiary), 6.01(a)(10) and 6.01(a)(11) shall not constitute Events of Default.

 

 Section 8.04            Conditions to Legal or Covenant Defeasance.

 

The following shall be
the conditions to the application of either Section 8.02 or 8.03 to the outstanding Notes:

 

(1)               
the Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders, cash in U.S. dollars, Government
Securities, or a combination thereof, in amounts as will be sufficient, as confirmed, certified or attested by an Independent Financial
Advisor in writing to the Trustee, without consideration of any reinvestment of interest, to pay the principal, premium, if any,
and interest due on the outstanding Notes on the Stated Maturity or on the applicable redemption date, as the case may be, and
the Company must specify whether the Notes are being defeased to maturity or to a particular redemption date;

 

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

 

    -85-

     

    

 

(3)               
in the case of Covenant Defeasance, the Company has delivered to the Trustee an Opinion of Counsel reasonably acceptable
to the Trustee confirming that, subject to customary assumptions and exclusions, the Holders and beneficial owners of Notes will
not recognize income, gain or loss for U.S. federal income tax purposes as a result of such Covenant Defeasance and will be subject
to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant
Defeasance had not occurred;

 

(4)               
no Default or Event of Default has occurred and is continuing on the date of such deposit or will occur as a result of such
deposit (other than a Default or an Event of Default resulting from the borrowing of funds to be applied to make such deposit and
any similar and simultaneous deposit relating to other Indebtedness and, in each case, the granting of Liens in connection therewith)
and the deposit will not result in a breach or violation of, or constitute a default under, the ABL Facility or any other material
agreement or material instrument (other than this Indenture) to which the Company or any Guarantor is a party or by which the Company
or any Guarantor is bound;

 

(5)               
the Company has delivered to the Trustee an Officers’ Certificate stating that the deposit was not made by the Company
with the intent of defeating, hindering, delaying or defrauding any creditors of the Company, any Guarantor or others;

 

(6)               
the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel (which Opinion of Counsel
may be subject to customary assumptions and exclusions reasonably acceptable to the Trustee), each stating that all conditions
precedent relating to the Legal Defeasance or the Covenant Defeasance, as the case may be, have been complied with; and

 

(7)               
the Company has delivered irrevocable instructions to the Trustee to apply the deposited money toward the payment of the
Notes at maturity or the redemption date, as the case may be (which instructions may be contained in the Officers’ Certificate
referred to in clause (6) above).

 

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

 

(a)               
Subject to Section 8.06, all money and Government Securities (including the proceeds thereof) deposited with the Trustee
pursuant to Section 8.04 in respect of the outstanding Notes shall be held in trust and applied by the Trustee, in accordance with
the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company
or a Guarantor acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to become
due thereon in respect of principal, premium and interest, but such money need not be segregated from other funds except to the
extent required by law.

 

    -86-

     

    

 

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

 

(c)               
Anything in this Article 8 to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to
time upon the request of the Company any money or Government Securities held by it as provided in Section 8.04 which, in the opinion
of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the
Trustee (which may be the opinion delivered under Section 8.04), 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 the Company.

 

Subject to any applicable
abandoned property law, any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the
payment of the principal, premium, if any, or interest on any Note and remaining unclaimed for two years after such principal,
premium, if any, or interest has become due and payable shall be paid to the Company on its request or (if then held by the Company)
shall be discharged from such trust; and the Holder of such Note shall thereafter look only to the Company for payment thereof,
and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee
thereof, shall thereupon cease; 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 or The Wall Street Journal (national
edition), notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days
from the date of such notification or publication, any unclaimed balance of such money then remaining shall be repaid to the Company.

 

 Section 8.07            Reinstatement.

 

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

Indenture) and the Trustee and the Notes Collateral Agent may amend or supplement this Indenture, the Notes, the Collateral
Documents, the Collateral Cooperation Agreement, the Intercreditor Agreements and any Note Guarantee with the consent of the
Holders of a majority in principal amount of the Notes (including Additional Notes, if any) then outstanding 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, any existing Default or Event of Default (other than a

amended or supplemental indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent
of the Holders of Notes as aforesaid, and upon receipt by the Trustee of the documents described in Section 7.02 and 13.02, the
Trustee and/or the Notes Collateral Agent shall join with the Company and the Guarantors in the execution of such amended or supplemental
indenture or security documents or intercreditor agreement unless such amended or supplemental indenture affects their own rights,
duties and liabilities or immunities under this Indenture or otherwise, in which case the Trustee and/or the Notes Collateral Agent
may in its discretion, but shall not be obligated to, enter into such amended or supplemental indenture or security documents or
intercreditor agreement.

 

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

 

(d)               
After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Company shall mail to Holders of
Notes a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice to all Holders,
or any defect therein, shall not, however, in any way impair or affect the validity of any such amended or supplemental indenture
or waiver.

 

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

 

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

 

(2)               
reduce the stated rate of interest or extend the stated time for payment of interest on any Note;

Notes with respect to a nonpayment default and a waiver of the payment default that resulted from such acceleration);

 

(5)                reduce
the premium payable upon the redemption or repurchase of any Note or change the time at which any Note may be redeemed or
repurchased as described in Section 3.07, Section 4.14 and Section 4.10 whether through an amendment or waiver of provisions
in the covenants, definitions or otherwise set forth herein (except amendments to the definitions of “Asset
Disposition” and “Change of Control”);

(6)               
make any Note payable in a currency other than that stated in the Note;

amend the contractual right expressly set forth in this Indenture or the Notes of any Holder to institute suit for the enforcement
of any payment on or with respect to such Holder’s Notes;

 

(8)               
make any change in the amendment or waiver provisions which require each Holder’s consent; or

 

(9)               
modify the Note Guarantees in any manner adverse to the Holders.

 

(f)                
In addition, without the consent of the Holders of at least 66 2/3% of the principal amount of the Notes then outstanding
(including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes),
no amendment, supplement or waiver may (1) modify any Collateral Document or the provisions in this Indenture dealing with Collateral
Documents or the application of trust moneys in any manner, taken as a whole, materially adverse to the Holders or otherwise release
a material portion of the Collateral other than in accordance with this Indenture, the Collateral Documents, the Collateral Cooperation
Agreement and the Intercreditor Agreements; or (2) modify the Collateral Cooperation Agreement or the Intercreditor Agreements
in any manner adverse to the Holders in any material respect other than in accordance with the terms of this Indenture, the Collateral
Documents, the Collateral Cooperation Agreement and the Intercreditor Agreements.

 

 Section 9.03            Revocation and Effect of Consents.

 

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

 

(b)               
The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to
consent to any amendment, supplement or waiver. If a record date is fixed, then, notwithstanding the preceding paragraph, those
Persons who were Holders at such record date (or their duly designated proxies), and only such Persons, shall be entitled to consent
to such amendment, supplement, or waiver or to revoke any consent previously given, whether or not such Persons continue to be
Holders after such record date. No such consent shall be valid or effective for more than 120 days after such record date unless
the consent of the requisite number of Holders has been obtained.

 

 Section 9.04            Notation on or Exchange of Notes.

 

(a)                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.

 

    -91-

     

    

 

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

 

 Section 9.05            Trustee and Notes Collateral Agent to Sign Amendments, Etc.

 

The Trustee and Notes
Collateral Agent shall sign any amendment, supplement or waiver authorized pursuant to this Article 9 if the Trustee and Notes
Collateral Agent determines that the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities
of the Trustee and Notes Collateral Agent. In executing any amendment, supplement or waiver to any Notes Document, the Trustee
and Notes Collateral Agent shall receive and (subject to Section 7.01) shall be fully protected in relying upon, in addition to
the documents required by Section 13.02, an Officers’ Certificate and an Opinion of Counsel stating that the execution of
such amended or supplemental indenture is authorized or permitted by this Indenture and that such amendment, supplement or waiver
is the legal, valid and binding obligation of the Company and any Guarantors party thereto, enforceable against each of them in
accordance with its terms, subject to customary exceptions, and complies with the provisions hereof.

 

 Section 9.06            Payment for Consent.

 

The Company will not,
and will not permit any of its Subsidiaries to, directly or indirectly, pay or cause to be paid any consideration to or for the
benefit of any Holder for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture
or the Notes unless such consideration is offered to all Holders and is paid to all Holders that consent, waive or agree to amend
in the time frame set forth in the solicitation documents relating to such consent, waiver or amendment; provided that if
such consents, waivers or amendments are sought in connection with an exchange offer where participation in such exchange offer
is limited to Holders who are “qualified institutional buyers,” within the meaning of Rule 144A, or non-U.S. persons,
within the meaning of Regulation S then such consideration need only be offered to all Holders to whom the exchange offer is made
and to be paid to all such Holders that consent, waive or agree to amend in such time frame.

GUARANTEES

 

 Section 10.01        Guarantee.

 

(a)                Subject
to this Article 10, each of the Guarantors hereby, jointly and severally, unconditionally guarantees, on a senior secured
basis, to each Holder of a Note and to the Trustee, the Notes Collateral Agent and their respective successors and assigns,
irrespective of the validity and enforceability of this Indenture, the Notes or the obligations of the Company hereunder or
thereunder, that: (a) the principal of, interest and premium on the Notes shall be promptly paid in full when due, whether at
maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the Notes, if
any, if lawful, and all other obligations of the Company to the Holders, the Trustee or the Notes Collateral Agent hereunder

thereof; and (b) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that
same shall 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 shall be jointly and severally obligated to pay or perform the same
immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection.

 

    -92-

     

    

 

(b)               
The Guarantors hereby agree that their obligations hereunder shall be unconditional, irrespective of the validity, regularity
or enforceability of the Notes, this Indenture, the other Notes Documents or the obligations of the Company hereunder or thereunder,
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 covenants that this Note Guarantee shall
not be discharged except by complete performance of the obligations contained in the Notes and this Indenture and the other Notes
Documents.

 

(c)               
Each Guarantor also agrees to pay any and all out-of-pocket costs and expenses (including reasonable attorneys’ fees)
incurred by the Trustee or any Holder in enforcing any rights under this Section 10.01.

 

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

 

(e)               
Each Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the Holders in respect of
any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Guarantor further agrees that,
as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the obligations
guaranteed hereby may be accelerated as provided in Article 6 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 (y) in the event
of any declaration of acceleration of such obligations as provided in Article 6, such obligations (whether or not due and payable)
shall forthwith become due and payable by the Guarantors for the purpose of this Note Guarantee. The Guarantors shall 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 Guarantees.

 

(f)                
Each Note Guarantee shall remain in full force and effect and continue to be effective should any petition be filed by or
against the Company for liquidation or reorganization, should the Company become insolvent or make an assignment for the benefit
of creditors or should a receiver or trustee be appointed for all or any significant part of the Company’s assets, and shall,
to the fullest extent permitted by law, continue to be effective or be reinstated, as the case may be, if at any time payment and
performance of the Notes are, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be restored or returned
by any obligee on the Notes or the Note Guarantees, whether as a “voidable preference,” “fraudulent transfer”
or otherwise, all as though such payment or performance had not been made. In the event that any payment, or any part thereof,
is rescinded, reduced, restored or returned, the Notes shall, to the fullest extent permitted by law, be reinstated and deemed
reduced only by such amount paid and not so rescinded, reduced, restored or returned.

 

    -93-

     

    

 

(g)

of the remaining provisions shall not in any way be affected or impaired thereby.

 

(h)               
The Note Guarantee issued by any Guarantor shall be a general senior obligation of such Guarantor and shall be pari passu
in right of payment with all existing and future senior Indebtedness of such Guarantor, if any.

Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance

the extent applicable to any Note Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors

to such maximum amount and all other contingent and fixed liabilities of such Guarantor that are relevant under such laws and after
giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor
in respect of the obligations of such other Guarantor under this Article 10, result in the obligations of such Guarantor under
its Note Guarantee not constituting a fraudulent conveyance or fraudulent transfer under applicable law. Each Guarantor that makes
a payment under its Note Guarantee shall be entitled upon payment in full of all guaranteed Obligations under this Indenture to
a contribution from each other Guarantor in an amount equal to such other Guarantor’s pro rata portion of such payment based
on the respective net assets of all the Guarantors at the time of such payment determined in accordance with GAAP.

the absence of the endorsement of any notation of such Guarantee on the Notes.

Note Guarantee set forth in this Indenture on behalf of the Guarantors.

 

(e)               
If required by Section 4.15, the Company shall cause any newly created or acquired Subsidiary to comply with the provisions

Each Guarantor shall
be subrogated to all rights of Holders of Notes against the Company in respect of any amounts paid by any Guarantor pursuant to
the provisions of Section 10.01; provided that, if an Event of Default has occurred and is continuing, no Guarantor shall
be entitled to enforce or receive any payments arising out of, or based upon, such right of subrogation until all amounts then
due and payable by the Company under this Indenture or the Notes shall have been paid in full.

consolidated balance sheet as of the end of the most recent fiscal quarter for which internal financial statements prepared on

in the case of any release in whole pursuant to clauses (1) through (3) above, all amounts owing to the Trustee and the Collateral
Agent under this Indenture, the Notes, the Note Guarantees, the Collateral Documents, the Collateral Cooperation Agreement and

(b)               
To the extent required by this Indenture, the Company or the Guarantors, as the case may be, will furnish to the Trustee
and Collateral Agent, prior to each proposed release of such Collateral pursuant to the Collateral Documents and this Indenture
an Officers’ Certificate as required by this Indenture; provided, however, in no event shall this Indenture require an Officers’
Certificate for (i) the release of a Lien on Collateral pursuant to Section 11.06(a)(7) above or (ii) the release of a Lien on
Collateral that is sold in the ordinary course of business to the extent such sale does not constitute an Asset Disposition or

provide for the release by the Collateral Agent of the released Collateral.

 

 Section 11.07        Suits To Protect the Collateral.

 

Subject to the provisions
of Article 7, the Collateral Documents, the Collateral Cooperation Agreement and the Intercreditor Agreements, the Trustee, without
the consent of the Holders, on behalf of the Holders, may or may direct the Notes Collateral Agent to take all actions it determines
in order to:

 

(a)               
enforce any of the terms of the Collateral Documents; and

 

(b)               
collect and receive any and all amounts payable in respect of the Obligations hereunder.

 

Subject to the provisions
of the Collateral Documents, the Collateral Cooperation Agreement and the Intercreditor Agreements, the Trustee and the Notes Collateral
Agent shall have power to institute and to maintain such suits and proceedings as the Trustee may determine to prevent any impairment
of the Collateral by any acts which may be unlawful or in violation of any of the Collateral Documents or this Indenture, and such
suits and proceedings as the Trustee may determine to preserve or protect its interests and the interests of the Holders in the
Collateral. Nothing in this Section 11.07 shall be considered to impose any such duty or obligation to act on the part of the Trustee
or the Notes Collateral Agent.

 

 Section 11.08        Authorization of Receipt of Funds by the Trustee Under the Collateral Documents.

 

Subject to the provisions
of the Intercreditor Agreements, the Trustee is authorized to receive any funds for the benefit of the Holders distributed under

 Section 11.09        Purchaser Protected.

 

In no event shall any
purchaser in good faith of any property purported to be released hereunder be bound to ascertain the authority of the Notes Collateral
Agent or the Trustee to execute the release or to inquire as to the satisfaction of any conditions required by the provisions hereof
for the exercise of such authority or to see to the application of any consideration given by such purchaser or other transferee;
nor shall any purchaser or other transferee of any property or rights permitted by this Article 11 to be sold be under any obligation
to ascertain or inquire into the authority of the Company or the applicable Guarantor to make any such sale or other transfer.

 

 Section 11.10        Powers Exercisable by Receiver or Trustee.

 

In case the Collateral
shall be in the possession of a receiver or trustee, lawfully appointed, the powers conferred in this Article 11 upon the Company
or a Guarantor with respect to the release, sale or other disposition of such property may be exercised by such receiver or trustee,
and an instrument signed by such receiver or trustee shall be deemed the equivalent of any similar instrument of the Company or
a Guarantor or of any Officer or Officers thereof required by the provisions of this Article 11; and if the Trustee shall be in
the possession of the Collateral under any provision of this Indenture, then such powers may be exercised by the Trustee.

 

 Section 11.11        Collateral Account.

 

(a)               
Prior to the Issue Date, the Trustee shall have established the Collateral Account, which shall at all times hereafter until
this Indenture shall have terminated, be maintained with, and under the sole control of, the Trustee. The Collateral Account shall
be a trust account and shall be established and maintained by the Trustee at one of its corporate trust offices (which may include
the New York corporate trust office) and all Collateral shall be credited thereto. All cash and Cash Equivalents received by the
Trustee from Asset Dispositions of Collateral, Recovery Events, foreclosures on or sales of Collateral or any other awards or proceeds
pursuant to the Collateral Documents, including earnings, revenues, rents, issues, profits and income from the Collateral received
pursuant to the Collateral Documents, shall be deposited in the Collateral Account to the extent required by this Indenture, the
Collateral Documents or the Intercreditor Agreements, and thereafter shall be held, applied and/or disbursed by the Trustee in
accordance with the terms of this Indenture (including, without limitation, Section 4.10, Section 6.13 and Section 11.08). In connection
with any and all deposits to be made into the Collateral Account under this Indenture, the Trustee shall receive an Officers’
Certificate directing the Trustee to make such deposit.

 

(b)               
Pending the distribution of funds in the Collateral Account in accordance with the provisions hereof and provided that no
Event of Default shall have occurred and be continuing, the Company may direct the Trustee to invest such funds in Cash Equivalents
specified in such direction, such investments to mature by the times such funds are needed hereunder and such direction to certify
that such funds constitute Cash Equivalents and that no Event of Default shall have occurred and be continuing. So long as no Event
of Default shall have occurred and be continuing, the Company may direct the Trustee to sell, liquidate or cause the redemption
of any such investments and to transmit the proceeds to the Company or its designee, in each case, to the extent permitted under
Section 4.10 hereof, such direction to certify that no Event of Default shall have occurred and be continuing. Any gain or income
on any investment of funds in the Collateral Account shall be credited to the Collateral Account. The Trustee shall have no liability
for any loss incurred in connection with any investment or any sale, liquidation or redemption thereof made in accordance with
the provisions of this Section 11.11(b).

 Section 11.12        Notes Collateral Agent.

 

(a)               
By their acceptance of the Notes, the Holders hereby designate and appoint the Trustee to serve as Notes Collateral Agent
and as their agent under this Indenture, the Collateral Documents, the Collateral Cooperation Agreement and the Intercreditor Agreements
and each of the Holders by acceptance of the Notes hereby irrevocably authorizes the Notes Collateral Agent to take such action
on its behalf under the provisions of this Indenture, the Collateral Documents, the Collateral Cooperation Agreement and the Intercreditor
Agreements and to exercise such powers and perform such duties as are expressly delegated to the Notes Collateral Agent by the
terms of this Indenture, the Collateral Documents, the Collateral Cooperation Agreement and the Intercreditor Agreements, and consents
and agrees to the terms of the Collateral Cooperation Agreement, the Intercreditor Agreements and each Collateral Document, as
the same may be in effect or may be amended, restated, supplemented or otherwise modified from time to time in accordance with
their respective terms. The Trustee hereby agrees to serve as Notes Collateral Agent under the Collateral Documents, the Collateral
Cooperation Agreement and the Intercreditor Agreements and acknowledges that the Notes Collateral Agent agrees to act as such on
the express conditions contained in this Section 11.12. Each Holder agrees that any action taken by the Notes Collateral Agent
in accordance with the provision of this Indenture, the Collateral Cooperation Agreement, the Intercreditor Agreements and the
Collateral Documents, and the exercise by the Notes 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,
the Collateral Documents, the Collateral Cooperation Agreement and the Intercreditor Agreements, the Notes Collateral Agent shall
not have any duties or responsibilities, except those expressly set forth herein and in the other Notes Documents to which the
Notes Collateral Agent is a party, nor shall the Notes Collateral Agent have or be deemed to have any trust or other fiduciary
relationship with the Trustee, any Holder or any Grantor, and no implied covenants, functions, responsibilities, duties, obligations
or liabilities shall be read into this Indenture, the Collateral Documents, the Collateral Cooperation Agreement or the Intercreditor
Agreements or otherwise exist against the Notes Collateral Agent.

 

(b)               
The Notes Collateral Agent may perform any of its duties or exercise any rights under this Indenture, the Collateral Documents,
the Collateral Cooperation Agreement or the Intercreditor Agreements by or through receivers, agents, employees, attorneys-in-fact
or through its Related Persons and shall be entitled to advice of counsel concerning all matters pertaining to such duties and
rights, and, in the absence of gross negligence or willful misconduct on its part, shall be entitled to act upon, and shall be
fully protected in taking action in reliance upon any advice or opinion given by legal counsel. The Notes Collateral Agent shall
not be responsible for the negligence or willful misconduct of any receiver, agent, employee, attorney-in-fact or Related Person
that it selects as long as such selection was made in good faith.

 

(c)                None
of the Notes Collateral Agent or any of its Related Persons shall (i) be liable for any action taken or omitted to be taken
by any of them under or in connection with this Indenture or the transactions contemplated hereby (except to the extent that
the foregoing are found by a final, non-appealable judgment of a court of competent jurisdiction to have resulted from its
own gross negligence or willful misconduct) or under or in connection with any Collateral Document, the Collateral
Cooperation Agreement or the Intercreditor Agreements or the transactions contemplated thereby (except to the extent that the
foregoing are found by a final, non-appealable judgment of a court of competent jurisdiction to have resulted from its own
gross negligence or willful misconduct), or (ii) be responsible in any manner to any of the Trustee or any Holder for any
recital, statement, representation, warranty, covenant or agreement made by the Company or any Grantor, or any Officer or
Related Persons thereof, contained in this Indenture, or any other Notes Documents, or in any certificate, report, statement
or other document referred to or provided for in, or received by the Notes Collateral Agent under or in connection with, this
Indenture, the Collateral Documents, the Collateral Cooperation Agreement or the Intercreditor Agreements, or the validity,
effectiveness, genuineness, enforceability or sufficiency of this Indenture, the Collateral Documents, the Collateral
Cooperation Agreement or the Intercreditor Agreements, or for any failure of any Grantor or any other party to this
Indenture, the Collateral Documents, the Collateral Cooperation Agreement or the Intercreditor Agreements to perform its
obligations hereunder or thereunder. None of the Notes Collateral Agent or any of its respective Related Persons shall be
under any obligation to the Trustee or any Holder to monitor, ascertain or inquire as to the observance or performance of any
of the agreements contained in, or conditions of, this Indenture, the Collateral Documents, the Collateral Cooperation
Agreement or the Intercreditor Agreements or to inspect the properties, books, or records of any Grantor or any
Grantor’s Affiliates.

 

    -101-

     

    

 

 

 

(d)               
In the absence of gross negligence or willful misconduct on its part, the Notes 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 Grantor), independent
accountants and other experts and advisors selected by the Notes Collateral Agent. The Notes 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 Notes Collateral Agent shall be fully
justified in failing or refusing to take any action under this Indenture, the Collateral Documents, the Collateral Cooperation
Agreement or the Intercreditor Agreements unless it shall first receive such advice or direction of the Trustee or the Holders
of a majority in aggregate principal amount of the Notes as it determines, or if there are any other Passu Lien Obligations then
outstanding, the Applicable Authorized Representative and, if it so requests, it shall first be indemnified to its satisfaction
by the Holders (or holders of other Pari Passu Lien Obligations (if any)) against any and all liability and expense which may be
incurred by it by reason of taking or continuing to take any such action. The Notes Collateral Agent shall in all cases be fully
protected in acting, or in refraining from acting, under this Indenture, the Collateral Documents, the Collateral Cooperation Agreement
or the Intercreditor Agreements in accordance with a written request, direction, instruction or consent of the Trustee or the Holders
of a majority in aggregate principal amount of the then outstanding Notes, or if there are any other Passu Lien Obligations then
outstanding, the Applicable Authorized Representative and such request and any action taken or failure to act pursuant thereto
shall be binding upon all of the Holders and holders of other Pari Passu Lien Obligations (if any).

 

(e)               
The Notes Collateral Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of
Default, unless a Responsible Officer of the Notes Collateral Agent shall have received written notice from the Trustee or the
Company referring to this Indenture, describing such Default or Event of Default and stating that such notice is a “notice
of default.” The Notes Collateral Agent shall take such action with respect to such Default or Event of Default as may be
directed by the Trustee in accordance with Article 6 or the Holders of a majority in aggregate principal amount of the Notes (subject
to this Section 11.12 and the terms of the Intercreditor Agreements).

 

(f)                 The
Notes Collateral Agent may resign at any time by notice to the Trustee and the Company, such resignation to be effective upon
the acceptance of a successor agent of its appointment as Notes Collateral Agent. If the Notes Collateral Agent resigns under
this Indenture, the Company shall appoint a successor notes collateral agent. If no successor notes collateral agent is
appointed by the Company prior to the intended effective date of the resignation of the Notes Collateral Agent (as stated in
the Notes Collateral Agent’s notice of resignation), the Notes Collateral Agent may appoint, after consulting with the
Trustee, subject to the consent of the Company (which shall not be unreasonably withheld and which shall not be required
during a continuing Event of Default), a successor notes collateral agent. If no successor notes collateral agent is
appointed and consented to by the Company pursuant to the preceding sentence within thirty (30) days after the intended
effective date of resignation (as stated in the Notes Collateral Agent’s notice of resignation), the Notes Collateral
Agent shall be entitled to petition a court of competent jurisdiction to appoint a successor. Upon the acceptance of its
appointment as successor notes collateral agent hereunder, such successor notes collateral agent shall succeed to all the
rights, powers and duties of the retiring Notes Collateral Agent, and the term “Notes Collateral Agent” shall
mean such successor notes collateral agent, and the retiring Notes Collateral Agent’s appointment, powers and duties as
the Notes Collateral Agent shall be terminated. After the retiring hereunder, the provisions of this Section 11.12 (and
Section 7.06) shall continue to inure to the benefit of the retiring Notes Collateral Agent and the retiring Notes Collateral
Agent shall not by reason of such resignation be deemed to be released from liability as to any actions taken or omitted to
be taken by it while it was the Notes Collateral Agent under this Indenture.

 

    -102-

     

    

 

(g)               
The Trustee shall initially act as Notes Collateral Agent and shall be authorized to appoint co-Notes Collateral Agents
as necessary in its sole discretion. Neither the Notes Collateral Agent nor any of its respective officers, directors, employees
or agents or other Related Persons shall be liable to any Grantor or any Noteholder Secured Party for failure to demand, collect
or realize upon any of the Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose
of any Collateral upon the request of any other Person or to take any other action whatsoever with regard to the Collateral or
any part thereof. The Notes Collateral Agent shall be accountable only for amounts that it actually receives as a result of the
exercise of such powers, and neither the Notes Collateral Agent nor any of its officers, directors, employees, attorneys, representatives
or agents shall be responsible for any act or failure to act hereunder, except to the extent such act is found by a final, non-appealable
judgment of a court of competent jurisdiction to have resulted from its own gross negligence or willful misconduct.

 

(h)               
By their acceptance of the Notes hereunder, the Notes Collateral Agent is authorized and directed by the Holders to (i)
enter into the Collateral Documents to which it is party, whether executed on or after the Issue Date, (ii) enter into the Collateral
Cooperation Agreement, (iii) enter into the Intercreditor Agreements, (iv) bind the Holders on the terms as set forth in the
Collateral Documents, the Collateral Cooperation Agreement and the Intercreditor Agreements, (v) perform and observe its obligations
under the Collateral Documents, the Collateral Cooperation Agreement and the Intercreditor Agreements and (vi) release any Collateral
in accordance with the terms hereof.

 

(i)                
The Trustee agrees that it shall not (and shall not be obliged to), and shall not instruct the Notes Collateral Agent to,
unless specifically directed to do so by the Holders of a majority in aggregate principal amount of the Notes, take or cause to
be taken any action to enforce its rights under this Indenture or the other Notes Documents or against any Grantor, including the
commencement of any legal or equitable proceedings, to foreclose any Lien on, or otherwise enforce any security interest in, any
of the Collateral.

 

(j)                 If
at any time or times the Trustee shall receive (i) by payment, foreclosure, set-off or otherwise, any proceeds of Collateral
or any payments with respect to the Obligations arising under, or relating to, this Indenture, except for any such proceeds
or payments received by the Trustee from the Notes Collateral Agent pursuant to the terms of this Indenture, or (ii) payments
from the Notes Collateral Agent in excess of the amount required to be paid to the Trustee pursuant to Article 6, the Trustee
shall promptly turn the same over to the Notes Collateral Agent, in kind, and with such endorsements as may be required to
negotiate the same to the Notes Collateral Agent, such proceeds to be applied by the Notes Collateral Agent pursuant to the
terms of this Indenture, the Collateral Documents, the Collateral Cooperation Agreement and the Intercreditor Agreements.

 

    -103-

     

    

 

(k)               
The Notes Collateral Agent is each Holder’s agent for the purpose of perfecting the Holders’ security interest
in assets which, in accordance with Article 9 of the Uniform Commercial Code, can be perfected only by possession. Should the Trustee
obtain possession of any such Collateral, upon request from the Company, the Trustee shall notify the Notes Collateral Agent thereof
and promptly shall deliver such Collateral to the Notes Collateral Agent or otherwise deal with such Collateral in accordance with
the Notes Collateral Agent’s instructions.

 

(l)                
No provision of this Indenture, the Collateral Cooperation Agreement, the Intercreditor Agreements or any Collateral Document
shall require the Notes Collateral Agent to expend or risk its own funds or otherwise incur any financial liability in the performance
of any of its duties hereunder or thereunder or to take or omit to take any action hereunder or thereunder or take any action at
the request or direction of Holders or, if there are other Pari Passu Lien Obligations then outstanding, the Applicable Authorized
Representative unless the Notes Collateral Agent shall have received indemnity satisfactory to the Notes Collateral Agent against
potential costs and liabilities incurred by the Notes Collateral Agent relating thereto. Notwithstanding anything to the contrary
contained in this Indenture, the Collateral Cooperation Agreement, the Intercreditor Agreements or the Collateral Documents, in
the event the Notes Collateral Agent is entitled or required to commence an action to foreclose or otherwise exercise its remedies
to acquire control or possession of the Collateral, the Notes Collateral Agent shall not be required to commence any such action
or exercise any remedy or to inspect or conduct any studies of any property under any mortgages or take any such other action if
the Notes Collateral Agent has determined that the Notes Collateral Agent may incur personal liability as a result of the presence
at, or release on or from, the Collateral or such property, of any hazardous substances unless the Notes Collateral Agent has received
security or indemnity from the Holders (and the holders of other Pari Passu Lien Obligations (if any)) in an amount and in a form
all satisfactory to the Notes Collateral Agent in its sole discretion, protecting the Notes Collateral Agent from all such liability.
The Notes Collateral Agent shall at any time be entitled to cease taking any action described above if it no longer reasonably
deems any indemnity, security or undertaking from the Company or the Holders (or holders of other Pari Passu Lien Obligations (if
any)) to be sufficient.

 

(m)             
The Notes Collateral Agent (i) shall not be liable for any action taken or omitted to be taken by it in connection with
this Indenture, the Collateral Cooperation Agreement, the Intercreditor Agreements and the Collateral Documents or any instrument
referred to herein or therein, except to the extent that any of the foregoing are found by a final, non-appealable judgment of
a court of competent jurisdiction to have resulted from its own gross negligence or willful misconduct, (ii) shall not be liable
for interest on any money received by it except as the Notes Collateral Agent may agree in writing with the Company (and money
held in trust by the Notes Collateral Agent need not be segregated from other funds except to the extent required by law) and (iii)
may consult with counsel of its selection and the advice or opinion of such counsel as to matters of law shall be full and complete
authorization and, in the absence of any gross negligence or willful misconduct on its part, protection from liability in respect
of any action taken, omitted or suffered by it in good faith and in reliance upon the advice or opinion of such counsel. The grant
of permissive rights or powers to the Notes Collateral Agent under the Notes Documents shall not be construed to impose duties
to act.

 

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

 

    -104-

     

    

 

(o)               
The Notes Collateral Agent does not assume any responsibility for any failure or delay in performance or any breach by the
Company or any other Grantor under this Indenture, the Collateral Cooperation Agreement, the Intercreditor Agreements and the Collateral
Documents. The Notes Collateral Agent shall not be responsible to the Holders or any other Person for any recitals, statements,
information, representations or warranties contained in any Notes Documents or in any certificate, report, statement, or other
document referred to or provided for in, or received by the Notes Collateral Agent under or in connection with, this Indenture,
the Collateral Cooperation Agreement, the Intercreditor Agreements or any Collateral Document; the execution, validity, genuineness,
effectiveness or enforceability of the Collateral Cooperation Agreement, the Intercreditor Agreements and any Collateral Documents
as to any other party thereto; the genuineness, enforceability, collectability, value, sufficiency, location or existence of any
Collateral, or the validity, effectiveness, enforceability, sufficiency, extent, perfection or priority of any Lien therein; or
the validity, enforceability or collectability of any Obligations; the assets, liabilities, financial condition, results of operations,
business, creditworthiness or legal status of any obligor. The Notes Collateral Agent shall have no obligation to any Holder or
any other Person to ascertain or inquire into the existence of any Default or Event of Default, the observance or performance by
any obligor of any terms of this Indenture, the Collateral Cooperation Agreement, the Intercreditor Agreements and the Collateral
Documents, or the satisfaction of any conditions precedent contained in this Indenture, the Collateral Cooperation Agreement, the
Intercreditor Agreements and any Collateral Document. The Notes Collateral Agent shall not be required to initiate or conduct any
litigation or collection or other proceeding under this Indenture, the Collateral Cooperation Agreement, the Intercreditor Agreements
and the Collateral Documents except as directed by Holders of a majority in aggregate principal amount of the Notes or, if other
Pari Passu Lien Obligations are then outstanding, the Applicable Authorized Representative; provided that in no event shall
the Notes Collateral Agent be required to take any action which it determines is not permitted pursuant to the Notes Documents
or applicable law.

 

(p)               
The parties hereto and the Holders hereby agree and acknowledge that the Notes Collateral Agent and the Trustee shall not
assume, be responsible for or otherwise be obligated for any liabilities, claims, causes of action, suits, losses, allegations,
requests, demands, penalties, fines, settlements, damages (including foreseeable and unforeseeable), judgments, expenses and costs
(including but not limited to, any remediation, corrective action, response, removal or remedial action, or investigation, operations
and maintenance or monitoring costs, for personal injury or property damages, real or personal) of any kind whatsoever, for any
environmental condition or contamination pursuant to any environmental law or otherwise as a result of this Indenture, the Collateral
Cooperation Agreement, the Intercreditor Agreements and the Collateral Documents or any actions taken pursuant hereto or thereto.
Further, the parties hereto and the Holders hereby agree and acknowledge that in the exercise of its rights under this Indenture,
the Collateral Cooperation Agreement, the Intercreditor Agreements and the Collateral Documents, the Notes Collateral Agent or
the Trustee may hold or obtain indicia of ownership primarily to protect the security interest of the Notes Collateral Agent in
the Collateral, including without limitation the properties constituting real property that constitute Collateral, and that any
such actions taken by the Notes Collateral Agent or the Trustee shall not be construed as or otherwise constitute any participation
in the management of such Collateral, including without limitation the real properties that constitute Collateral, as those terms
are defined in Section 101(20) of the Comprehensive Environmental Response, Compensation, and Liability Act, 42 U.S.C. §§
9601 et seq., as amended.

 

(q)                Upon
the receipt by the Notes Collateral Agent of a written request of the Company signed by two Officers (a “Collateral
Document Order”), the Notes Collateral Agent is hereby authorized to execute and enter into, and if satisfactory in
form and substance to the Notes Collateral Agent, execute and enter into, without the further consent of any Holder or the
Trustee, any Collateral Document to be executed after the Issue Date. Such Collateral Document Order shall (i) state that it
is being delivered to the Notes Collateral Agent pursuant to, and is a Collateral Document Order referred to in, this Section
11.12(q), and (ii) instruct the Notes Collateral Agent to execute and enter into such Collateral Document. Any such execution
of a Collateral Document shall be at the direction and expense of the Company, upon delivery to the Notes Collateral Agent of
an Officers’ Certificate and Opinion of Counsel stating that all conditions precedent to the execution and delivery of
the Collateral Document have been satisfied. The Holders, by their acceptance of the Notes, hereby authorize and direct the
Notes Collateral Agent to execute such Collateral Documents.

 

    -105-

     

    

 

(r)               
After the occurrence and during the continuance of an Event of Default and subject to the terms of the Intercreditor Agreements,
the Trustee, subject to Articles 6 and 7, may direct the Notes Collateral Agent in connection with any action required or permitted
by this Indenture, the Collateral Documents, the Collateral Cooperation Agreement or the Intercreditor Agreements.

 

(s)              
The Notes Collateral Agent is authorized to receive any funds for the benefit of itself, the Trustee and the Holders distributed
under the Collateral Documents, the Collateral Cooperation Agreement or the Intercreditor Agreements and to the extent not prohibited
under the terms of any such agreement, for turnover to the Trustee to make further distributions of such funds to itself, the Trustee
and the Holders in accordance with the provisions of Section 6.13 and the other provisions of this Indenture, the Collateral Cooperation
Agreement and the Intercreditor Agreements.

 

(t)               
In each case that Notes Collateral Agent may or is required hereunder or under any other Notes Document to take any action
(an “Action”), including without limitation to make any determination, to give consents, to exercise rights,
powers or remedies, to release or sell Collateral or otherwise to act hereunder or under any other Notes Document, the Notes Collateral
Agent may seek direction from the Holders of a majority in aggregate principal amount of the then outstanding Notes or, if otherwise
specified under the Pari Passu Intercreditor Agreement, the Applicable Authorized Representative. In the absence of gross negligence
or willful misconduct on its part, the Notes Collateral Agent shall not be liable with respect to any Action taken or omitted to
be taken by it in accordance with the direction from the Holders of a majority in aggregate principal amount of the then outstanding
Notes or, if otherwise specified under the Pari Passu Intercreditor Agreement, the Applicable Authorized Representative. Subject
to the terms of the Pari Passu Intercreditor Agreement, if the Notes Collateral Agent shall request direction from the Holders
of a majority in aggregate principal amount of the then outstanding Notes with respect to any Action, the Notes Collateral Agent
shall be entitled to refrain from such Action unless and until the Notes Collateral Agent shall have received direction from the
Holders of a majority in aggregate principal amount of the then outstanding Notes, and the Notes Collateral Agent shall not incur
liability to any Person by reason of so refraining.

 

(u)              
Notwithstanding anything to the contrary in this Indenture or any other Notes Document, in no event shall the Notes Collateral
Agent be responsible for, or have any duty or obligation with respect to, the recording, filing, registering, perfection, protection
or maintenance of the security interests or Liens intended to be created by this Indenture or the other Notes Documents (including
the filing or continuation of any UCC financing or continuation statements or similar documents or instruments), nor shall the
Notes Collateral Agent be responsible for, and the Notes Collateral Agent makes no representation regarding, the validity, effectiveness
or priority of any of the Collateral Documents or the security interests or Liens intended to be created thereby.

 

    -106-

     

    

 

(v)               Before
the Notes Collateral Agent acts or refrains from acting in each case at the request or direction of the Company or the Guarantors,
or in connection with any Collateral Document, the Collateral Cooperation Agreement or the Intercreditor Agreements, it may require
an Officers’ Certificate and an Opinion of Counsel, which shall conform to the provisions of Section 13.03. In the absence
of gross negligence or willful misconduct on its part, the Notes Collateral Agent shall not be liable for any action it takes
or omits to take in good faith in reliance on such certificate or opinion.

 

(w)             
Notwithstanding anything to the contrary contained herein but subject to the terms of the Intercreditor Agreements, the
Notes Collateral Agent shall act pursuant to the instructions of the Noteholder Secured Parties as provided in this Indenture solely
with respect to the Collateral Documents and the Collateral.

 

(x)                The
Trustee and Notes Collateral Agent shall be under no obligation to effect or maintain insurance or to renew any policies of insurance
or to inquire as to the sufficiency of any policies of insurance carried by the Company or any Guarantor, or to report, or make
or file claims or proof of loss for, any loss or damage insured against or that may occur, or to keep itself informed or advised
as to the payment of any taxes or assessments, or to require any such payment to be made.

 

(y)               The
Trustee and Notes Collateral Agent shall not be obligated to acquire possession of or take any action with respect to any property
secured by a mortgage or deed of trust, if as a result of such action, the Trustee would be considered to hold title to, to be
a “mortgagee in possession of”, or to be an “owner” or “operator” of such property within
the meaning of the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, as amended from time to time,
but the Trustee or Notes Collateral Agent may determine, based upon a report prepared by a person who regularly conducts environmental
audits, that (i) the such property is in compliance with applicable environmental laws or, if not, that it would be in the best
interest of the Holders to take such actions as are necessary for such property to comply therewith and (ii) there are not circumstances
present at such property relating to the use, management or disposal of any hazardous wastes for which investigation, testing,
monitoring, containment, clean-up or remediation could be required under any federal, state or local law or regulation or that
if any such materials are present for which such action could be required, that it would be in the best economic interest of the
Holders to take such actions with respect to such property. Notwithstanding the foregoing, before taking any such action, the
Trustee and Notes Collateral Agent may require that a satisfactory indemnity bond or environmental impairment insurance be furnished
to it for the payment or reimbursement of all expenses to which it may be put and to protect it against all liability resulting
from any claims, judgments, damages, losses, fees, penalties or expenses which may result from such action.

 

(z)               
In no event shall the Notes Collateral Agent be required to execute and deliver any landlord lien waiver, estoppel or collateral
access letter, or any account control agreement that the Notes Collateral Agent determines adversely affects it or otherwise subjects
it to personal liability, including without limitation agreements to provide indemnity to any contractual counterparty.

 

 Section 11.13        Information Regarding Collateral.

 

(a)               The
Company will furnish to the Collateral Agent, with respect to the Company or any Guarantor, promptly (and in any event within
30 days of such change) written notice of any change in such Person’s (1) legal name, (2) jurisdiction of
organization or formation or (3) identity or corporate structure. The Company and the Guarantors will agree not to effect
or permit any change referred to in the preceding sentence unless all filings have been made under the Uniform Commercial Code
and any other applicable laws that are required by this Indenture and/or the Collateral Documents in order for the Collateral
to be made subject to the Lien of the Collateral Agent under this Indenture and/or the Collateral Documents in the manner and
to the extent required by this Indenture or any of the Collateral Documents and shall take all necessary action so that such Lien
is perfected with the same priority as immediately prior to such change to the extent required by this Indenture and/or the Collateral
Documents. The Company also agrees promptly to notify the Collateral Agent if any material portion of the Collateral is damaged,
destroyed or condemned.

 

    -107-

     

    

 

(b)               Each
year, within 120 days after the end of the preceding fiscal year, the Company shall deliver to each of the Trustee and the
Collateral Agent a certificate of a financial officer setting forth the information required pursuant to the schedules required
by the Collateral Documents or confirming that there has been no change in such information since the date of the prior annual
certification.

 

 Section 11.14        Negative Pledge.

 

The Company and each
Guarantor will not, and the Company will not permit any of its Subsidiaries to, further pledge the Collateral as security or otherwise,
subject to Permitted Liens. The Company, however, subject to compliance with Sections 2.01, 2.15 and 4.12, has the ability under
this Indenture to issue an unlimited aggregate principal amount of Additional Notes, all of which may be secured by the Collateral.

 

ARTICLE 12

SATISFACTION AND DISCHARGE

 

 Section 12.01        Satisfaction and Discharge.

 

This Indenture and the
Collateral Documents shall be discharged and shall cease to be of further effect as to all Notes and security granted for the Notes
and the Note Guarantees, when either:

 

(1)               
all Notes theretofore authenticated and delivered (except lost, stolen or destroyed Notes that have been replaced or paid
and Notes for whose payment money has been deposited in trust) have been delivered to the Trustee for cancellation; or

 

(2)              
(A)     all Notes not theretofore delivered to the Trustee for cancellation have become due and payable by reason of the
giving of a notice of redemption or otherwise, will become due and payable within one year or are to be called for redemption within
one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and
at the expense, of the Company, 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, Government Securities, or a combination thereof,
in such amounts as will be sufficient, as confirmed, certified or attested to by an Independent Financial Advisor in writing to
the Trustee, without consideration of any reinvestment of interest, to pay and discharge the entire Indebtedness on the Notes not
theretofore delivered to the Trustee for cancellation for principal, premium, if any, and accrued interest to the date of maturity
or redemption, as the case may be;

 

(B)              no
Default or Event of Default has occurred and is continuing on the date of such deposit or will occur as a result of such
deposit (other than a Default or an Event of Default resulting from the borrowing of funds to be applied to make such deposit
and any similar and simultaneous deposit relating to other Indebtedness and, in each case, the granting of Liens in
connection therewith) and the deposit will not result in a breach or violation of, or constitute a default under, the ABL
Facility or any other material agreement or material instrument (other than this Indenture) to which the Company or any
Guarantor is a party or by which the Company or any Guarantor is bound;

 

    -108-

     

    

 

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

 

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

 

In addition, the Company
shall deliver to the Trustee an Officers’ Certificate and an Opinion of Counsel (which Opinion of Counsel may be subject
to customary assumptions and exclusions reasonably acceptable to the Trustee) each stating that all conditions precedent to satisfaction
and discharge have been satisfied.

 

Notwithstanding the satisfaction
and discharge of this Indenture, if money shall have been deposited with the Trustee pursuant to subclause (A) of clause (2) of
this Section 12.01, the provisions of Section 12.02 and Section 8.06 shall survive.

 

 Section 12.02        Application of Trust Money.

 

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

 

If the Trustee or Paying
Agent is unable to apply any money or Government Securities in accordance with Section 12.01 by reason of any legal proceeding
or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such
application, the Company’s and any Guarantor’s obligations under this Indenture and the Notes shall be revived and
reinstated as though no deposit had occurred pursuant to Section 12.01; provided that if the Company has made any payment
of principal of, premium 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.

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

 

1.       INTEREST.
United States Steel Corporation, a Delaware corporation, promises to pay interest on the principal amount of this Note at 12.000%
per annum from May 29, 2020 (or the most recent Interest Payment Date) until maturity. The Company will pay interest semi-annually
in arrears on June 1 and December 1 of each year, or if any such day is not a Business Day, on the next succeeding Business Day
(each, an “Interest Payment Date”). Interest on the Notes will accrue from the most recent date to which interest
has been paid or, if no interest has been paid, from the date of issuance; provided that the first Interest Payment Date
shall be December 1, 2020. The Company will pay interest (including post-petition interest in any proceeding under any Bankruptcy
Law) on overdue principal and premium, if any, from time to time on demand at the interest rate on the Notes; it shall pay interest
(including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest, if any, (without
regard to any applicable grace periods) from time to time on demand at the interest rate on the Notes. Interest will be computed
on the basis of a 360-day year comprised of twelve 30-day months.

 

2.       METHOD

Name: ________________________

 

Address: ______________________

 

Taxpayer ID Number: _____________

 

The undersigned represents
and warrants to you that:

 

1. We are an institutional
 “accredited investor” (as defined in Rule 501(a)(1), (2), (3) or (7) under the Securities Act of 1933, as amended (the
 “Securities Act”)), purchasing for our own account or for the account of such an institutional “accredited
investor” at least $250,000 principal amount of the Notes, and we are acquiring the Notes, for investment purposes and not
with a view to, or for offer or sale in connection with, any distribution in violation of the Securities Act. We have such knowledge
and experience in financial and business matters as to be capable of evaluating the merits and risks of our investment in the Notes,
and we invest in or purchase securities similar to the Notes in the normal course of our business. We, and any accounts for which
we are acting, are each able to bear the economic risk of our or its investment.

 

2. We understand
that the Notes have not been registered under the Securities Act and, unless so registered, may not be sold except as
permitted in the following sentence. We agree on our own behalf and on behalf of any investor account for which we are
purchasing Notes to offer, sell or otherwise transfer such Notes prior to the date that is one year after the later of the
date of original issue and the last date on which the Company or any affiliate of the Company was the owner of such Notes (or
any predecessor thereto) (the “Resale Restriction Termination Date”) only in accordance with the Private
Placement Legend (as such term is defined in the indenture under which the Notes were issued) on the Notes and any applicable
securities laws of any state of the United States of America. The foregoing restrictions on resale will not apply subsequent
to the Resale Restriction Termination Date. If any resale or other transfer of the Notes is proposed to be made to another
such institutional “accredited investor” above prior to the Resale Restriction Termination Date, the transferor
shall deliver a letter from the transferee substantially in the form of this letter to the Company and the Trustee, which
shall provide, among other things, that the transferee is an institutional “accredited investor” within the
meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act and that it is acquiring such Notes for investment
purposes and not for distribution in violation of the Securities Act. Each purchaser acknowledges that the Company and the
Trustee reserve the right prior to the offer, sale or other transfer prior to the Resale Restriction Termination Date of the
Notes with respect to applicable transfers described in the Restricted Notes Legend to require the delivery of an opinion of
counsel, certifications and/or other information satisfactory to the Company and the Trustee.

an “Intervening Lien”, and any such Person being referred to as an “Intervening
Creditor”), or (b) the existence of any Collateral securing First Lien Obligations of any other Class that
does not constitute Shared Collateral with respect to First Lien Obligations of such Class (any condition referred to in
clause (a) or (b) with respect to First Lien Obligations of such Class being referred to as an
 “Impairment” of such Class). In the event an Impairment exists with respect to First Lien Obligations of
any Class, the results of such Impairment shall be borne solely by the Secured Parties of such Class, and the rights of the
Secured Parties of such Class (including the right to receive distributions in respect of First Lien Obligations of such
Class pursuant to Section 2.01(b)) set forth herein shall be modified to the extent necessary so that the results of
such Impairment are borne solely by the Secured Parties of such Class. In furtherance of the foregoing, in the event First
Lien Obligations of any Class shall be subject to an Impairment in the form of an Intervening Lien of any Intervening
Creditor, the value of any Shared Collateral or Proceeds that are allocated to such Intervening Creditor shall be deducted
solely from the Shared Collateral or Proceeds to be distributed in respect of First Lien Obligations of such Class. In
addition, in the event the First Lien Obligations of any Class are modified pursuant to applicable law (including pursuant to
Section 1129 of the Bankruptcy Code), any reference to the First Lien Obligations of such Class or the First Lien
Documents of such Class shall refer to such obligations or such documents as so modified.

2.03. Actions with Respect to Shared Collateral; Prohibition on Certain Contests. (a) Notwithstanding anything
to the contrary in the First Lien Credit Documents (other than this Agreement), (i) only the Collateral Agent shall, and
shall have the right to, exercise, or refrain from exercising, any rights, remedies and powers with respect to the Shared
Collateral, including any action to enforce its security interest in or realize upon any Shared Collateral and any right,
remedy or power with respect to any Shared Collateral under any intercreditor agreement (other than this Agreement), and then
only on the instructions of the Applicable Authorized Representative, (ii) the Collateral Agent shall not be required
to, and shall not, follow any instructions or directions with respect to Shared Collateral (including with respect to any
intercreditor agreement with respect to any Shared Collateral) from any Non-Controlling Authorized Representative (or any
other Secured Party, other than the Applicable Authorized Representative), it being understood and agreed that,
notwithstanding any such instruction or direction by the Applicable Authorized Representative, the Collateral Agent shall not
be required to take any action that, in its opinion, could expose the Collateral Agent to liability or be contrary to any
First Lien Security Document or applicable law, and (iii) no Non-Controlling Authorized Representative or any other Secured
Party (other than the Applicable Authorized Representative) shall, or shall instruct the Collateral Agent to, commence any
judicial or nonjudicial foreclosure proceedings with respect to, seek to have a trustee, receiver, liquidator or similar
official appointed for or over, attempt any action to take possession of, take any other action to enforce its security
interest in or realize upon, or exercise any other right, remedy or power with respect to (including any right, remedy or
power under any intercreditor agreement other than this Agreement) any Shared Collateral, whether under any First Lien Credit
Document, applicable law or otherwise, it being agreed that only the Collateral Agent, acting on the instructions of the
Applicable Authorized Representative and in accordance with the applicable First Lien Security Documents, shall be entitled
to take any such actions or exercise any such rights, remedies and powers with respect to Shared Collateral. Notwithstanding
the equal priority of the Liens established under Section 2.01(a), the Collateral Agent (acting on the instructions of the
Applicable Authorized Representative) may deal with the Shared Collateral as if the Collateral Agent had a senior Lien on
such Collateral. No Non-Controlling Authorized Representative or Non-Controlling Secured Party will contest, protest or
object to any foreclosure proceeding or action brought by the Collateral Agent, the Applicable Authorized Representative or
any Controlling Secured Party, or any other exercise by the Collateral Agent (acting on the instructions of the Applicable
Authorized Representative), the Applicable Authorized Representative or any Controlling Secured Party of any rights, remedies
or powers with respect to the Shared Collateral, or seek to cause the Collateral Agent to do so. Nothing in this paragraph
shall be construed to limit the rights and priorities of the Collateral Agent, any Authorized Representative or any other
Secured Party with respect to any Collateral not constituting Shared Collateral.

validity, attachment, creation, perfection, priority or enforceability of a Lien held by or on behalf of the Collateral Agent or
any other Authorized Representative or any of its Related Secured Parties in all or any part of the Collateral, (ii) the validity,
enforceability or effectiveness of any First Lien Obligation of any Class or any First Lien Security Document of any Class or (iii)
the validity, enforceability or effectiveness of the priorities, rights or duties established by, or other provisions of, this

expected to be, to interfere, hinder or delay, in any manner, whether by judicial proceedings or otherwise, any sale,
transfer or other disposition of the Shared Collateral by the Collateral Agent, (ii) except as provided in
Section 2.03, neither such Authorized Representative nor its Related Secured Parties shall have any right (A) to
direct the Collateral Agent or any other Secured Party to exercise any right, remedy or power with respect to any Shared
Collateral (including pursuant to any intercreditor agreement) or (B) to consent to the exercise by the Collateral Agent
or any other Secured Party of any right, remedy or power with respect to any Shared Collateral, (iii) neither such Authorized
Representative nor its Related Secured Parties will (and each hereby waives any right to) institute any suit or proceeding,
or assert in any suit or proceeding any claim, against the Collateral Agent or any other Secured Party seeking damages from
or other relief by way of specific performance, instructions or otherwise with respect to any Shared Collateral, and none of
the Collateral Agent, any Applicable Authorized Representative or any other Secured Party shall be liable for any action
taken or omitted to be taken by the Collateral Agent, such Applicable Authorized Representative or such other Secured Party
with respect to any Shared Collateral in accordance with the provisions of this Agreement, and (iv) neither such
Authorized Representative nor its Related Secured Parties will (and each hereby waives any right to) seek to have any Shared
Collateral or any part thereof marshaled upon any foreclosure or other disposition of such Shared Collateral; provided
that nothing in this Agreement shall be construed to prevent or impair the rights of the Collateral Agent or any Authorized
Representative or any of its Related Secured Parties to enforce this Agreement.

or any of its Related Secured Parties shall at any time obtain possession of any Shared Collateral or receive any Proceeds (other

of each other Class, (i) such Authorized Representative or its Related Secured Party, as the case may be, shall promptly inform
each Authorized Representative thereof, (ii) such Authorized Representative or its Related Secured Party shall hold such Shared
Collateral or Proceeds in trust for the benefit of the Secured Parties of any Class entitled thereto pursuant to Section 2.01(b)
and (iii) such Authorized Representative or its Related Secured Party shall promptly transfer such Shared Collateral or Proceeds
to the Collateral Agent, for distribution in accordance with Section 2.01(b).

 

SECTION
2.05. Automatic Release of Liens; Amendments to First Lien Security Documents. (a) Notwithstanding anything to the
contrary in the First Lien Credit Documents or First Lien Security Documents (but subject to the provisions of Section 11.03 of
the Indenture in the case of the release of a material portion of the “Collateral” (as defined in the Indenture) from
the Liens of the Security Documents), if at any time the Collateral Agent forecloses upon or otherwise exercises rights, remedies
and powers against any Shared Collateral resulting in a disposition thereof, then (whether or not any Insolvency or Liquidation
Proceeding is pending at the time) the Liens on such Shared Collateral in favor of the Collateral Agent, for the benefit of the
Secured Parties of all Classes, will automatically be released and discharged; provided that any Proceeds realized therefrom
shall be applied pursuant to Section 2.01(b).

 

(b)
Each of the Authorized Representatives, for itself and on behalf of its Related Secured Parties, acknowledges and agrees
that (i) the Collateral Agent may enter into any amendment or other modification to any First Lien Security Document so long as
the Collateral Agent receives a certificate of the Company stating that such amendment or other modification is permitted by the
terms of the First Lien Credit Documents of each Class and (ii) the Collateral Agent may enter into any amendment or other modification
to any First Lien Security Document solely as such First Lien Security Document relates to First Lien Obligations of a particular
Class so long as (A) such amendment or modification is in accordance with the First Lien Credit Documents of such Class and
(B) such amendment or modification does not adversely affect the interests of the Secured Parties of any other Class.

 

(c)
Each Authorized Representative agrees to execute and deliver (at the sole cost and expense of the Grantors) all such consents,
confirmations, authorizations and other instruments as shall reasonably be requested by the Collateral Agent to evidence and confirm
any release of Shared Collateral or amendment or modification to any First Lien Security Document provided for in this Section.

SECTION
2.06. Certain Agreements with Respect to Bankruptcy and Insolvency Proceedings. (a) The Authorized
Representative of each Class, for itself and on behalf of its Related Secured Parties, agrees that, if any Company or any
other Grantor shall become subject to a case (a “Bankruptcy Case”) under the Bankruptcy Code and shall, as
debtor-in-possession, move for approval of financing (“DIP Financing”) to be provided by one or more
lenders (the “DIP Lenders”) under Section 364 of the Bankruptcy Code or any equivalent provision of
any other Bankruptcy Law or the use of cash collateral under Section 363 of the Bankruptcy Code or any equivalent
provision of any other Bankruptcy Law, neither such Authorized Representative nor its Related Secured Parties will raise any
objection to any such financing or to the Liens on the Shared Collateral securing any such financing (“DIP Financing
Liens”) or to any use of cash collateral that constitutes Shared Collateral, in each case unless the Applicable
Authorized Representative shall then oppose or object to such DIP Financing or such DIP Financing Liens or such use of cash
collateral (and (i) to the extent that such DIP Financing Liens are senior to the Liens on any such Shared Collateral
for the benefit of the Controlling Secured Parties, each Non-Controlling Secured Party will subordinate its Liens with
respect to such Shared Collateral on the same terms as the Liens of the Controlling Secured Parties (other than any Liens of
any Controlling Secured Parties constituting DIP Financing Liens) are subordinated thereto, and (ii) to the extent that
such DIP Financing Liens rank pari passu with the Liens on any such Shared Collateral granted to secure the First Lien
Obligations of the Controlling Secured Parties, each Non-Controlling Secured Party will confirm the priorities with respect
to such Shared Collateral as set forth herein), in each case so long as (A) the Secured Parties of such Class retain the
benefit of their Liens on all such Shared Collateral subject to the DIP Financing Liens, including proceeds thereof arising
after the commencement of the Bankruptcy Case, with such Liens having the same priority with respect to Liens of the Secured
Parties of any other Class (other than any Liens of the Secured Parties of such other Class constituting DIP Financing Liens)
as existed prior to the commencement of the Bankruptcy Case, (B) the Secured Parties of such Class are granted Liens on
any additional collateral provided to the Secured Parties of any other Class as adequate protection or otherwise in
connection with such DIP Financing or use of cash collateral, with such Liens having the same priority with respect to Liens
of the Secured Parties of any other Class (other than any Liens of the Secured Parties of such other Class constituting DIP
Financing Liens) as existed prior to the commencement of the Bankruptcy Case, (C) if any amount of such DIP Financing or
cash collateral is applied to repay any First Lien Obligations, such amount is applied in accordance with
Section 2.01(b), and (D) if the Secured Parties of any Class are granted adequate protection, including in the form
of periodic payments, in connection with such DIP Financing or use of cash collateral, the proceeds of such adequate
protection are applied in accordance with Section 2.01(b); provided that the Secured Parties of each Class shall
have a right to object to the grant, as security for the DIP Financing, of a Lien on any Collateral subject to Liens in favor
of the Secured Parties of such Class or its Authorized Representative that shall not constitute Shared Collateral; and provided
further that any Secured Party receiving adequate protection granted in connection with the DIP Financing or such use of
cash collateral shall not object to any other Secured Party receiving adequate protection comparable to any such adequate
protection granted to such Secured Party.

 

SECTION

respect to the First Lien Obligations of any Class previously made shall be rescinded for any reason whatsoever (including an order

shall be fully applicable thereto until all the First Lien Obligations of such Class shall again have been paid in full in cash.

 

SECTION
2.08. Insurance and Condemnation Awards. As between the Secured Parties, the Collateral Agent, acting at the direction
of the Applicable Authorized Representative, shall have the exclusive right, subject to the rights of the Grantors under the First
Lien Security Documents, to settle and adjust claims in respect of Shared Collateral under policies of insurance covering or constituting
Shared Collateral and to approve any award granted in any condemnation or similar proceeding, or any deed in lieu of condemnation,
in respect of the Shared Collateral; provided that any Proceeds arising therefrom shall be subject to Section 2.01(b).

without notice to, or the consent of, any Secured Party of any other Class, all without affecting the priorities provided for herein
or the other provisions hereof; provided that nothing in this Section shall affect any limitation on any such Refinancing
that is set forth in the First Lien Credit Documents of any such other Class; and provided further that, if any obligations
of the Grantors in respect of such Refinancing Indebtedness shall be secured by Liens on any Shared Collateral, then such obligations
and the holders thereof shall be subject to and bound by the provisions of this Agreement and the Authorized Representative of
the holders of any such Refinancing Indebtedness shall have executed an Additional Authorized Representative Joinder Agreement.

 

SECTION
2.10. Possessory Collateral Agent as Gratuitous Bailee for Perfection. (a) The Collateral Agent agrees to hold any
Shared Collateral constituting Possessory Collateral that is part of the Collateral in its possession or control (or in the possession
or control of its agents or bailees) as gratuitous bailee for the benefit of each other Secured Party and any assignee solely for
the purpose of perfecting the security interest granted in such Possessory Collateral, if any, pursuant to the applicable First
Lien Security Documents, in each case subject to the terms and conditions of this Section. Pending delivery to the Collateral Agent,
each Authorized Representative agrees to hold any Shared Collateral constituting Possessory Collateral, from time to time in its
possession, as gratuitous bailee for the benefit of each other Secured Party and any assignee, solely for the purpose of perfecting
the security interest granted in such Possessory Collateral, if any, pursuant to the applicable First Lien Security Documents,
in each case, subject to the terms and conditions of this Section.

 

(b)
The duties or responsibilities of the Collateral Agent and each Authorized Representative under this Section shall

Determinations with Respect to Obligations and Liens

 

Whenever, in connection
with the exercise of its rights or the performance of its obligations hereunder, the Collateral Agent or the Authorized Representative
of any Class shall be required to determine the existence or amount of any First Lien Obligations of any Class, or the Shared Collateral
subject to any Lien securing the First Lien Obligations of any Class (and whether such Lien constitutes a valid and perfected Lien),
it may request that such information be furnished to it in writing by the Authorized Representative of such Class and shall be
entitled to make such determination on the basis of the information so furnished; provided that if, notwithstanding such
request, the Authorized Representative of the applicable Class shall fail or refuse reasonably promptly to provide the requested
information, the requesting Collateral Agent or Authorized Representative shall be entitled to make any such determination by such
method as it may, in the exercise of its good faith judgment, determine, including by reliance upon an Officers’ Certificate.
The Collateral Agent and each Authorized Representative may rely conclusively, and shall be fully protected in so relying, on any
determination made by it in accordance with the provisions of the preceding sentence (or as otherwise directed by a court of competent
jurisdiction) and shall have no liability to any Grantor, any Secured Party or any other Person as a result of such determination
or any action or not taken pursuant thereto.

Concerning the Collateral Agent

 

SECTION
4.01. Appointment and Authority. (a) Each of the Authorized Representatives, for itself and on behalf of its Related
Secured Parties, hereby irrevocably appoints U.S. Bank National Association to act as the Collateral Agent hereunder and under
each of the First Lien Security Documents, and authorizes the Collateral Agent to take such actions and to exercise such powers
as are delegated to the Collateral Agent by the terms hereof or thereof, including for purposes of acquiring, holding and enforcing
any and all Liens on Collateral granted by any Grantor to secure any of the First Lien Obligations, together with such actions
and powers as are reasonably incidental thereto. In addition, to the extent required under the laws of any jurisdiction other than
the United States, each of the Authorized Representatives, for itself and on behalf of its Related Secured Parties, hereby grants
to the Collateral Agent any required powers of attorney to execute any First Lien Security Document governed by the laws of such
jurisdiction on such Secured Party’s behalf. Without limiting the generality of the foregoing, the Collateral Agent is hereby
expressly authorized to execute any and all documents (including releases) with respect to the Shared Collateral, and the rights
of the Secured Parties with respect thereto, as contemplated by and in accordance with the provisions of this Agreement and the
First Lien Security Documents.

 

(b) Each
of the Authorized Representatives, for itself and on behalf of its Related Secured Parties, acknowledges and agrees that the
Collateral Agent shall be entitled, for the benefit of the Secured Parties, to sell, transfer or otherwise dispose of or deal
with any Shared Collateral as provided herein and in the First Lien Security Documents, without regard to any rights,
remedies or powers to which the Non-Controlling Secured Parties would otherwise be entitled to as a result of their holding
First Lien Obligations. Without limiting the foregoing, each of the Authorized Representatives, for itself and on behalf of
its Related Secured Parties, agrees that none of the Collateral Agent, the Applicable Authorized Representative or any other
Secured Party shall have any duty or obligation first to marshal or realize upon any type of Shared Collateral (or any other
Collateral securing any of the First Lien Obligations), or to sell, dispose of or otherwise liquidate all or any portion of
such Shared Collateral (or any other Collateral securing any First Lien Obligations), in any manner that would maximize the
return to the Non-Controlling Secured Parties, notwithstanding that the order and timing of any such realization, sale,
disposition or liquidation may affect the amount of proceeds actually received by the Non-Controlling Secured Parties from
such realization, sale, disposition or liquidation. Each of the Authorized Representatives, for itself and on behalf of its
Related Secured Parties, waives any claim they may now or hereafter have against the Collateral Agent or the Authorized
Representative or any Secured Party of any other Class arising out of (i) any actions that the Collateral Agent or any
such Authorized Representative or Secured Party takes or omits to take (including actions with respect to the creation,
perfection or continuation of Liens on any Collateral, actions with respect to the foreclosure upon, sale or other
disposition, release or depreciation of, or failure to realize upon, any of the Collateral and actions with respect to the
collection of any claim for all or any part of the First Lien Obligations from any account debtor, guarantor or any other
party) in accordance with the First Lien Security Documents or any other agreement related thereto or to the collection of
the First Lien Obligations or the valuation, use, protection or release of any security for the First Lien Obligations,
(ii) any election by any Applicable Authorized Representative or Secured Parties, in any proceeding instituted under the
Bankruptcy Code, of the application of Section 1111(b) of the Bankruptcy Code or (iii) subject to Section 2.06, any
borrowing by, or grant of a security interest or administrative expense priority under Section 364 of the Bankruptcy
Code or any equivalent provision of any other Bankruptcy Law by, the Company or any of its respective Subsidiaries, as
debtor-in-possession. Notwithstanding any other provision of this Agreement, the Collateral Agent shall not accept any Shared
Collateral in full or partial satisfaction of any First Lien Obligations pursuant to Section 9-620 of the Uniform
Commercial Code of any jurisdiction without the consent of each Authorized Representative representing Secured Parties for
whom such Collateral constitutes Shared Collateral.

 

    E-16

     

    

 

(c)
Each of the Authorized Representatives, for itself and on behalf of its Related Secured Parties, acknowledges and agrees
that, upon any other obligations being designated hereunder as Additional First Lien Obligations or any other Person becoming an
Additional Authorized Representative or any other Persons becoming Additional Secured Parties, the Collateral Agent will continue
to act in its capacity as Collateral Agent in respect of the then existing Authorized Representatives and Secured Parties and such
Additional Authorized Representative and Additional Secured Parties.

 

SECTION

Lien Credit Documents and may exercise the same as though it were not the Collateral Agent and the term “Secured Party”,
 “Secured Parties”, “Indenture Secured Party”, “Indenture Secured Parties”, “Additional
Secured Party” or “Additional Secured Parties”, as applicable, shall, unless otherwise expressly indicated or
unless the context otherwise requires, include the Person serving as the Collateral Agent hereunder in its individual capacity.
The Person serving as the Collateral Agent and its Affiliates may accept deposits from, lend money to, act as the financial advisor
or in any other advisory capacity for and generally engage in any kind of business with the Company or any of its respective Subsidiary
or other Affiliate thereof as if such Person were not the Collateral Agent hereunder and without any duty to account therefor to
any other Secured Party.

set forth herein and in the other First Lien Security Documents. Without limiting the generality of the foregoing, the Collateral
Agent:

occurred and is continuing;

 

(ii) shall
not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers
expressly contemplated hereby or by the First Lien Security Documents that the Collateral Agent is required to exercise as directed

any action that, in its opinion or the opinion of its counsel, may expose the Collateral Agent to liability or that is contrary
to any First Lien Security Document or applicable law;

Affiliates in any capacity;

Class or the Company in accordance with the applicable First Lien Credit Document; and

 

(vi) shall
not be responsible for or have any duty to ascertain or inquire into (A) any statement, warranty or representation made in

document delivered hereunder or thereunder or in connection herewith or therewith, (C) the performance or observance of any
of the covenants, agreements or other terms or conditions set forth herein or therein or the occurrence of any Default or Event
of Default, (D) the validity, enforceability, effectiveness or genuineness of this Agreement, any First Lien Security Document
or any other agreement, instrument or document, or the validity, attachment, creation, perfection, priority or enforceability of
any Lien purported to be created by the First Lien Security Documents, (E) the value or the sufficiency of any Collateral
for First Lien Obligations of any Class or (F) the satisfaction of any condition set forth in any First Lien Credit Document,
other than to confirm receipt of items expressly required to be delivered to the Collateral Agent.

 

SECTION
4.04. Reliance by Collateral Agent. The Collateral Agent shall be entitled to rely, and shall not incur any liability
for relying, upon any notice, request, certificate, consent, statement, instrument, document or other writing (including any electronic
message, Internet or intranet website posting or other distribution) believed by it to be genuine and to have been signed, sent
or otherwise authenticated by the proper Person. The Collateral Agent also shall be entitled to rely, and shall not incur any liability
for relying, upon any statement made to it orally or by telephone and believed by it to have been made by the proper Person. The
Collateral Agent may consult with legal counsel (who may be counsel for the Company, any other Grantor or any Authorized Representative),
independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance
with the advice of any such counsel, accountants or experts.

 

SECTION

powers hereunder or under any other First Lien Security Document by or through any one or more sub-agents appointed by the Collateral
Agent. The Collateral Agent and any such sub-agent may perform any and all of its duties and exercise its rights and powers by
or through their respective Affiliates. The exculpatory provisions of this Article shall apply to any such sub-agent and to the
Affiliates of the Collateral Agent and any such sub-agent, and shall apply to their respective activities as the Collateral Agent.

 

SECTION
4.06. Resignation of Collateral Agent. The Collateral Agent may at any time give notice of its resignation as
Collateral Agent under this Agreement and the First Lien Security Documents to each Authorized Representative and the
Company. Upon receipt of any such notice of resignation, the Applicable Authorized Representative shall have the right, in
consultation with the Company, to appoint a successor. If no such successor shall have been so appointed by the Applicable
Authorized Representative and shall have accepted such appointment within 30 days after the retiring Collateral Agent
gives notice of its resignation, then the retiring Collateral Agent may, on behalf of the Secured Parties, appoint a
successor Collateral Agent meeting the qualifications set forth above; provided that if the Collateral Agent shall
notify each Authorized Representative and the Company that no qualifying Person has accepted such appointment, then such
resignation shall nonetheless become effective in accordance with such notice and (a) the retiring Collateral Agent
shall be discharged from its duties and obligations hereunder and under the First Lien Security Documents (except that in the
case of any Collateral held by the Collateral Agent on behalf of the Secured Parties under any First Lien Security Document,
the retiring Collateral Agent shall continue to hold such Collateral solely for purposes of maintaining the perfection of the
security interests of the Secured Parties therein until such time as a successor Collateral Agent is appointed but with no
obligation to take any further action at the request of the Applicable Authorized Representative or any other Secured
Parties) and (b) all payments, communications and determinations provided to be made by, to or through the Collateral
Agent shall instead be made by or to each Authorized Representative directly, until such time as the Applicable Authorized
Representative appoints a successor Collateral Agent as provided above. Upon the acceptance of a successor’s
appointment as Collateral Agent hereunder and under the First Lien Security Documents, such successor shall succeed to and
become vested with all of the rights, powers, privileges and duties of the retiring (or retired) Collateral Agent, and the
retiring Collateral Agent shall be discharged from all of its duties and obligations hereunder or under the First Lien
Security Documents (if not already discharged therefrom as provided above). Notwithstanding the resignation of the Collateral
Agent hereunder and under the First Lien Security Documents, the provisions of this Article and the equivalent provision of
any Additional First Lien Document shall continue in effect for the benefit of such retiring Collateral Agent, its sub-agents
and their respective Related Secured Parties in respect of any actions taken or omitted to be taken by any of them while the
retiring Collateral Agent was acting as Collateral Agent. Upon any notice of resignation of the Collateral Agent hereunder
and under the First Lien Security Documents, the Company agrees to use commercially reasonable efforts to transfer (and
maintain the validity and priority of) the Liens in favor of the retiring Collateral Agent under the First Lien Security
Documents to the successor Collateral Agent.

and delivering an Additional Authorized Representative Joinder Agreement and provide that upon such execution and delivery, such

Statements and Other Filings. Each Grantor agrees to file on the Issue Date the initial Uniform Commercial Code financing
statements describing the Collateral other than, with respect to Fixtures that are located on any of the Specified Fixtures

terms of the Indenture. Each Grantor hereby authorizes the Collateral Agent to file at any time and from time to time any

Each Grantor hereby represents
and warrants to the Collateral Agent and each other Notes Secured Party that:

 

3.1              
Title; No Other Liens. Except for the security interest granted to the Collateral Agent for the ratable benefit
of the Notes Secured Parties pursuant to this Agreement and the other Liens permitted to exist on the Collateral pursuant to the
terms of the Indenture, such Grantor owns each item of the Collateral free and clear of any and all Liens or claims of others.
No financing statement or other public notice with respect to all or any part of the Collateral is (or, with respect to any Fixtures
that are located on any of the Specified Fixtures Real Properties, will be upon the filing of fixture filings in accordance with
and subject to the terms of the Indenture) on file or of record in any public office, except such as have been filed in favor of
the Collateral Agent, for the ratable benefit of the Notes Secured Parties, pursuant to this Agreement or as are permitted by the
Indenture. For the avoidance of doubt, it is understood and agreed that any Grantor may, as part of its business, grant licenses
to third parties to use Intellectual Property owned or developed by a Grantor. For purposes of this Agreement and the other Notes
Documents, such licensing activity shall not constitute a “Lien” on such Intellectual Property. Each of the Collateral
Agent and the other Notes Secured Parties understands that any such licenses may be exclusive to the applicable licensees, and
such exclusivity provisions may limit the ability of the Collateral Agent to utilize, sell, lease or transfer the related Intellectual
Property or otherwise realize value from such Intellectual Property pursuant hereto.

 

3.2               Perfected
First Priority Liens. The security interests granted pursuant to this Agreement (a) upon completion of the filings and
other actions specified on Schedule 3 (which, in the case of all filings and other documents referred to on said Schedule,
have been delivered to the Collateral Agent in completed and duly executed form) will constitute valid perfected security
interests in all of the Collateral in which a security interest may be created under the New York UCC and in the Intellectual
Property which is registered or becomes registered or the subject of an application for registration with the U.S. Copyright
Office or the U.S. Patent and Trademark Office in favor of the Collateral Agent, for the ratable benefit of the Notes Secured
Parties, as collateral security for such Grantor’s Notes Obligations, enforceable in accordance with the terms hereof
against all creditors of such Grantor and any Persons purporting to purchase any Collateral from such Grantor, subject to the
effects of bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other similar laws relating to or
affecting creditors’ rights generally, general equitable principles (whether considered in a proceeding in equity or at
law) and an implied covenant of good faith and fair dealing, and (b) are prior to all other Liens on the Collateral in
existence on the date hereof except for Permitted Liens that have priority over the Liens on the Collateral by operation of
law.

 

    10

     

    

 

3.3              
Jurisdiction of Organization; Chief Executive Office. On the date hereof, such Grantor’s jurisdiction

of incorporation or other organization document and long-form good standing certificate as of a date which is recent to the date

3.6

Subsidiary Voting Stock, if less, 65% of the outstanding Foreign Subsidiary Voting Stock of each relevant Issuer.

 

(b)               
All the shares of the Pledged Stock have been duly and validly issued and are fully paid and nonassessable.

 

(c)               
Each of the Pledged Notes (if any) constitutes the legal, valid and binding obligation of the obligor with respect
thereto, enforceable in accordance with its terms, subject to the effects of bankruptcy, insolvency, fraudulent conveyance, reorganization,
moratorium and other similar laws relating to or affecting creditors’ rights generally, general equitable principles (whether
considered in a proceeding in equity or at law) and an implied covenant of good faith and fair dealing.

 

(d)               
Such Grantor is the record and beneficial owner of, and has good and marketable title to, the Investment Property
pledged by it hereunder, free of any and all Liens, except for Permitted Liens, or options in favor of, or claims of, any other
Person, except the security interest created by this Agreement.

Except as set forth in Schedule 6(c), on the date hereof, none of the material Intellectual Property is the
subject of any licensing or franchise agreement pursuant to which such Grantor is the licensor or franchisor.

 

(d)               
Except as set forth in Schedule 6(d), on the date hereof, no holding, decision or judgment has been rendered
by any Governmental Authority which would limit, cancel or question the validity of, or such Grantor’s rights in, any Intellectual
Property in any respect that could reasonably be expected to have a material adverse effect on the value of any Intellectual Property.

 

    11

     

    

 

(e)               
Except as set forth in Schedule 6(e), on the date hereof, no action or proceeding is pending, or, to the knowledge
of such Grantor, threatened, on the date hereof (i) seeking to limit, cancel or question the validity of any Intellectual Property
or such Grantor’s ownership interest therein, or (ii) which, if adversely determined, would have a material adverse effect

Upon the filing of a financing statement covering any Commercial Tort Claim referred to in Section 4.9 hereof against
such Grantor in the jurisdiction specified in Schedule 3 hereto, the security interest granted in such Commercial Tort Claim will
constitute a valid perfected security interest in favor of the Collateral Agent, for the ratable benefit of the Notes Secured Parties,
as collateral security for such Grantor’s Notes Obligations, enforceable in accordance with the terms hereof against all
creditors of such Grantor and any Persons purporting to purchase such Collateral from Grantor, subject to the effects of bankruptcy,
insolvency, fraudulent conveyance, reorganization, moratorium and other similar laws relating to or affecting creditors’
rights generally, general equitable principles (whether considered in a proceeding in equity or at law) and an implied covenant
of good faith and fair dealing, which security interest shall be prior to all other Liens on such Collateral except for Permitted
Liens that have priority over the Liens on such Collateral by operation of law.

LLC, 90 days from the Issue Date and (B) with respect to insurance policies held by the Company, 60 days from the Issue Date (i)
provide that no cancellation, material reduction in amount or material change in coverage thereof shall be effective until at least

or in respect of income or profits therefrom, as well as all claims of any kind (including, without limitation, claims for labor,
materials and supplies) against or with respect to the Collateral, except that no such tax, assessment, charge or levy need be
paid if the amount or validity thereof is currently being contested in good faith by appropriate proceedings and reserves in conformity
with GAAP with respect thereto have been provided on the books of such Grantor or where the failure to pay could not reasonably
be expected to result in the sale, forfeiture or loss of any material portion of the Collateral or any material interest therein.

 

4.4              
Maintenance of Perfected Security Interest; Further Documentation. (a) Such Grantor shall maintain the security

described in this clause (ii) no later than 10 Business Days following the Company’s filing of its annual and quarterly financial
statements with the Securities and Exchange Commission, irrespective of whether there has been a written request of the Collateral
Agent; and (iii) in the case of Investment Property, Letter-of-Credit Rights and any other relevant Collateral, taking any actions
reasonably necessary to enable the Collateral Agent to obtain “control” (within the meaning of the applicable Uniform
Commercial Code) with respect thereto; provided that such Grantor will not be required to take any such actions in any jurisdiction
outside the United States; and provided further, that the Collateral Agent shall have no obligation to review or investigate
the contents or adequacy of these instruments, documents or actions. For the avoidance of doubt, the Collateral Agent has no duty

reasonable detail, of:

 

(a)               
any Lien (other than security interests created hereby or Liens permitted pursuant to the terms of the Indenture)
on any of the Collateral which would adversely affect the ability of the Collateral Agent to exercise any of its remedies hereunder;
and

 

(b)

(including, without limitation, any certificate representing a dividend or a distribution in connection with any reclassification,

as additional collateral security for the Notes Obligations. If any sums of money or property so paid or distributed in respect
of the Investment Property shall be received by such Grantor, such Grantor shall, until such money or property is paid or delivered
to the Collateral Agent, hold such money or property in trust for the Collateral Agent and the other Notes Secured Parties, segregated

Without the prior written consent of the Collateral Agent, such Grantor will not (i) sell, assign, transfer, exchange,
or otherwise dispose of, or grant any option with respect to, the Investment Property or Proceeds thereof (except pursuant to a
transaction made in compliance with the Indenture), (ii) create, incur or permit to exist any Lien (except for Permitted Liens)
or option in favor of, or any claim of any Person with respect to, any of the Investment Property or Proceeds thereof, or any interest
therein, except for the security interests created by this Agreement or (iii) enter into any agreement or undertaking restricting
the right or ability of such Grantor or the other Notes Secured Parties to sell, assign or transfer any of the Investment Property
or Proceeds thereof (except to the extent not prohibited by the Indenture).

In the case of each Grantor which is an Issuer, such Issuer agrees that (i) it will be bound by the terms of this
Agreement relating to the Investment Property issued by it and will comply with such terms insofar as such terms are applicable
to it, (ii) it will notify the Collateral Agent promptly in writing of the occurrence of any of the events described in Section

Property issued by it.

 

    14

     

    

 

4.8              
Intellectual Property. (a) Such Grantor will, and will use commercially reasonable efforts to cause its licensees
to, (i) continue to use each material Trademark on each and every trademark class of goods applicable to its current operations
in order to maintain such material Trademark in full force free from any claim of abandonment for non-use, (ii) maintain as in
the past the quality of products and services offered under such material Trademark, (iii) use such material Trademark with the
appropriate notice of registration and all other notices and legends required by applicable law, (iv) not adopt or use any mark

of the Notes Secured Parties, shall obtain a perfected security interest in such mark pursuant to this Agreement, and (v) not do
any act or knowingly omit to do any act whereby such material Trademark may become invalidated or impaired in any way.

 

(b)               
Such Grantor will not, and will use commercially reasonable efforts to cause its licensees not to, do any act, or
omit to do any act, whereby any material Patent may become forfeited, abandoned or dedicated to the public.

 

(c)               
Such Grantor will, and will use commercially reasonable efforts to cause its licensees to, (i) employ each material
registered Copyright and (ii) not do any act or knowingly omit to do any act whereby any registered Copyrights may become invalidated
or otherwise impaired. Such Grantor will not, and will use commercially reasonable efforts to cause its licensees not to, do any
act whereby any registered Copyrights may fall into the public domain.

 

(d)               
Such Grantor will not, and will use commercially reasonable efforts to cause its licensees not to, do any act that
knowingly uses any material Intellectual Property to infringe the intellectual property rights of any other Person.

 

(e)               
Such Grantor will notify the Collateral Agent and the other Notes Secured Parties promptly if it knows that any application
or registration relating to any material Intellectual Property may become forfeited, abandoned or dedicated to the public, or of
any adverse determination or development (including, without limitation, the institution of, or any such determination or development
in, any proceeding in the United States Patent and Trademark Office, the United States Copyright Office or any court or tribunal
in any country) regarding such Grantor’s ownership of, or the validity of, any material Intellectual Property or such Grantor’s
right to register the same or to own and maintain the same.

 

(f)                
Whenever such Grantor, either by itself or through any agent, employee, licensee or designee, shall acquire, become
the exclusive licensee of or file an application for the registration of any Intellectual Property with the United States Patent
and Trademark Office, the United States Copyright Office or any similar office or agency in any other country or any political

statements pursuant to Section 4.03 of the Indenture for the fiscal quarter in which such filing occurs, and (ii) such Intellectual
Property shall automatically become part of the Collateral consisting of Intellectual Property subject to the terms and conditions
of this Agreement with respect thereto. Upon the reasonable request of the Collateral Agent, such Grantor shall execute and deliver,
and have recorded, any and all agreements, instruments, documents, and papers as the Collateral Agent may reasonably request to
evidence the Collateral Agent’s and the other Notes Secured Parties’ security interest in any Copyright, Patent or
Trademark and the goodwill and general intangibles of such Grantor relating thereto or represented thereby.

 

(g)                Such
Grantor will exercise its reasonable business judgment consistent with prudent business practice, including, without
limitation, in any proceeding before the United States Patent and Trademark Office, the United States Copyright Office or any
similar office or agency in any other country or any political subdivision thereof, to maintain and pursue each application
(and to obtain the relevant registration) and to maintain each registration of the material Intellectual Property, including,
without limitation, filing of applications for renewal, affidavits of use and affidavits of incontestability.

 

    15

Grantor shall (i) take such actions as such Grantor shall reasonably deem appropriate under the circumstances to protect such Intellectual
Property and (ii) if such Intellectual Property is of material economic value, promptly notify the Collateral Agent after it learns
thereof and, if such Grantor shall reasonably deem it to be appropriate under the circumstances, sue for infringement, misappropriation
or dilution, seek injunctive relief where appropriate and recover any and all damages for such infringement, misappropriation or
dilution.

 

(i)               Each

Intellectual Property owned by such Grantor by making appropriate filings with the United States Patent and Trademark Office and
United States Copyright Office no later than 60 days after the date hereof, and will provide documentation of such filings to Collateral
Agent no later than 10 days after making same.

Commercial Tort Claims. If such Grantor shall obtain an interest in any Commercial Tort Claim with a potential
value in excess of $1,000,000, such Grantor shall within 30 days of obtaining such interest supplement Schedule 7 with a description

SECTION
5.      REMEDIAL PROVISIONS

 

5.1              
Pledged Stock; Intellectual Property. (a) Unless an Event of Default shall have occurred and be continuing
and the Collateral Agent shall have given notice to the relevant Grantor of the Collateral Agent’s intent to exercise its
corresponding rights pursuant to Section 5.1(b), each Grantor shall be permitted to receive all cash dividends paid in respect
of the Pledged Stock and all payments made in respect of the Pledged Notes, to the extent permitted in the Indenture, and to exercise
all voting and corporate or other organizational rights with respect to the Investment Property; provided, however, that no vote
shall be cast or corporate or other organizational right exercised or other action taken which would have a material adverse effect
on the value of the Collateral.

 

(b)                If
an Event of Default shall occur and be continuing and the Collateral Agent shall give notice of its intent to exercise such
rights to the relevant Grantor or Grantors (in all cases, with a copy to the Company), (i) the Collateral Agent shall have
the right to receive any and all cash dividends, payments or other Proceeds paid in respect of the Investment Property and
make application thereof to the Notes Obligations in such order as the Collateral Agent may determine, and (ii) any or all of
the Investment Property shall be registered in the name of the Collateral Agent or its nominee, and the Collateral Agent or
its nominee may thereafter exercise (x) all voting, corporate and other rights pertaining to such Investment Property at any
meeting of shareholders of the relevant Issuer or Issuers or otherwise and (y) any and all rights of conversion, exchange and
subscription and any other rights, privileges or options pertaining to such Investment Property as if it were the absolute
owner thereof (including, without limitation, the right to exchange at its discretion any and all of the Investment Property
upon the merger, consolidation, reorganization, recapitalization or other fundamental change in the corporate or other

or option pertaining to such Investment Property, and in connection therewith, the right to deposit and deliver any and all
of the Investment Property with any committee, depositary, transfer agent, registrar or other designated agency upon such
terms and conditions as the Collateral Agent may determine), all without liability except to account for property actually
received by it, but the Collateral Agent shall have no duty to any Grantor to exercise any such right, privilege or option
and shall not be responsible for any failure to do so or delay in so doing.

 

    16

     

    

 

(c)               
Each Grantor hereby authorizes and instructs each Issuer of any Investment Property pledged by such Grantor hereunder
to (i) comply with any instruction received by it from the Collateral Agent in writing that (x) states that an Event of Default
has occurred and is continuing and (y) is otherwise in accordance with the terms of this Agreement, without any other or further
instructions from such Grantor, and each Grantor agrees that each Issuer shall be fully protected in so complying, and (ii) unless
otherwise expressly permitted hereby pursuant to Section 4.7(a), pay any dividends or other payments with respect to the Investment
Property directly to the Collateral Agent.

 

(d)               
For the purpose of enabling the Collateral Agent to exercise the rights and remedies under this Agreement at such
time as the Collateral Agent shall be lawfully entitled to exercise such rights and remedies, each Grantor hereby (i) grants to
the Collateral Agent, for the benefit of the Collateral Agent and the Holders, an irrevocable, nonexclusive license (exercisable
without payment of royalty or other compensation to any Grantor) to use, license or sublicense any Intellectual Property now owned
or hereafter acquired by such Grantor, and wherever the same may be located, and including in such license access to all media
in which any of the licensed items may be recorded or stored and to all software and programs used for the compilation or printout
thereof, the right to prosecute and maintain all Intellectual Property and the right to sue for past, present or future infringement
of the Intellectual Property; and (ii) irrevocably agrees that the Collateral Agent may sell any of such Grantor's inventory directly
to any person, including without limitation persons who have previously purchased the Grantor's inventory from such Grantor and
in connection with any such sale or other enforcement of the Collateral Agent's rights under this Agreement, may sell inventory
which bears any Trademark owned by or licensed to such Grantor and any inventory that is covered by any Copyright owned by or licensed
to such Grantor and the Collateral Agent may finish any work in process and affix any Trademark owned by or licensed to such Grantor
and sell such inventory as provided herein.

 

5.2              
Proceeds to be Turned Over To Collateral Agent. If an Event of Default shall occur and be continuing, all
Proceeds received by any Grantor consisting of cash, checks and other near-cash items shall be held by such Grantor in trust for
the Collateral Agent and the other Notes Secured Parties, segregated from other funds of such Grantor, and shall, forthwith upon
receipt by such Grantor, be turned over to the Collateral Agent in the exact form received by such Grantor (duly indorsed by such
Grantor to the Collateral Agent, if required). All Proceeds received by the Collateral Agent hereunder shall be held by the Collateral
Agent in a Collateral Account maintained under its sole dominion and control. All Proceeds while held by the Collateral Agent in
a Collateral Account (or by such Grantor in trust for the Collateral Agent and the other Notes Secured Parties) shall continue
to be held as Collateral security for all the Notes Obligations and shall not constitute payment thereof until applied as provided
in Section 5.3.

 

5.3              
Application of Proceeds. If an Event of Default shall have occurred and be continuing, at any time at the
Collateral Agent’s election, the Collateral Agent may apply all or any part of Proceeds constituting Collateral, whether
or not held in any Collateral Account in payment of the Notes Obligations in the following order:

 

First,
to pay unpaid fees and expenses of the Collateral Agent under the Notes Documents;

 

Second,
to pay unpaid fees and expenses of the Trustee under the Notes Documents;

 

Third,
to the Collateral Agent, for application by it towards payment of amounts then due and owing and remaining unpaid in respect
of the Notes Obligations, pro rata among the Notes Secured Parties according to the amounts of the Notes Obligations
then due and owing and remaining unpaid to the Notes Secured Parties; and

 

Fourth,
any balance remaining after the Notes Obligations shall have been paid in full over to the Company or to whomsoever may be lawfully
entitled to receive the same.

 

    17

     

    

 

5.4              
Code and Other Remedies. If an Event of Default shall occur and be continuing, the Collateral Agent, on behalf
of the Notes Secured Parties, may, and upon the request of the Notes Secured Parties shall, exercise, in addition to all other
rights and remedies granted to them in this Agreement and in any other instrument or agreement securing, evidencing or relating
to the Notes Obligations, all rights and remedies of a secured party under the New York UCC or any other applicable law. Without
limiting the generality of the foregoing, the Collateral Agent, without demand of performance or other demand, presentment, protest,
advertisement or notice of any kind (except any notice required by law referred to below) to or upon any Grantor or any other Person
(all and each of which demands, defenses, advertisements and notices are hereby waived), may in such circumstances forthwith collect,
receive, appropriate and realize upon the Collateral, or any part thereof, and/or may forthwith sell, lease, assign, give option
or options to purchase, or otherwise dispose of and deliver the Collateral or any part thereof (or contract to do any of the foregoing),
in one or more parcels at public or private sale or sales, at any exchange, broker’s board or office of the Collateral Agent
or any other Notes Secured Party or elsewhere upon such terms and conditions as it may deem advisable and at such prices as it
may deem best, for cash or on credit or for future delivery without assumption of any credit risk. The Collateral Agent or any
other Notes Secured Party shall have the right upon any such public sale or sales, and, to the extent permitted by law, upon any
such private sale or sales, to purchase the whole or any part of the Collateral so sold, free of any right or equity of redemption
in any Grantor, which right or equity is hereby waived and released. Each Grantor further agrees, at the Collateral Agent’s
request, to assemble the Collateral and make it available to the Collateral Agent at places which the Collateral Agent shall reasonably
select, whether at such Grantor’s premises or elsewhere. The Collateral Agent shall apply the net proceeds of any action
taken by it pursuant to this Section 5.4, after deducting all reasonable costs and expenses of every kind incurred in connection
therewith or incidental to the care or safekeeping of any of the Collateral or in any way relating to the Collateral or the rights
of the Collateral Agent and the other Notes Secured Parties hereunder, including, without limitation, reasonable attorneys’
fees and disbursements, to the payment in whole or in part of the Notes Obligations, in accordance with Section 5.3, and only after
such application and after the payment by the Collateral Agent of any other amount required by any provision of law, including,
without limitation, Section 9-615(a)(3) of the New York UCC, need the Collateral Agent account for the surplus, if any, to any
Grantor. To the extent permitted by applicable law, each Grantor waives all claims, damages and demands it may acquire against
the Collateral Agent or any other Notes Secured Party arising out of the exercise by them of any rights hereunder. If any notice
of a proposed sale or other disposition of Collateral shall be required by law, such notice shall be deemed reasonable and proper
if given at least 10 days before such sale or other disposition.

 

    18

     

    

 

5.5              
Other Agreements With Respect to Sales of Pledged Stock

 

(a)                If
the Collateral Agent shall determine to exercise its right to sell any or all of the Pledged Stock pursuant to Section 5.4,
and if in the opinion of the Collateral Agent it is necessary or advisable to have the Pledged Stock, or that portion thereof
to be sold, registered under the provisions of the Securities Act, the relevant Grantor will cause the Issuer thereof to (i)
execute and deliver, and cause the directors and officers of such Issuer to execute and deliver, all such instruments and
documents, and do or cause to be done all such other acts as may be, in the opinion of the Collateral Agent, necessary or
advisable to register the Pledged Stock, or that portion thereof to be sold, under the provisions of the Securities Act, (ii)
use commercially reasonable efforts to cause the registration statement relating thereto to become effective and to remain
effective for a period of one year from the date of the first public offering of the Pledged Stock, or that portion thereof
to be sold, and (iii) make all amendments thereto and/or to the related prospectus which, in the opinion of the Collateral
Agent, are necessary or advisable, all in conformity with the requirements of the Securities Act and the rules and
regulations of the Securities and Exchange Commission applicable thereto.  Each Grantor agrees to cause such Issuer to
comply with the provisions of the securities or “Blue Sky” laws of any and all jurisdictions which the Collateral
Agent shall designate and to make available to its security holders, as soon as practicable, an earnings statement (which
need not be audited) which will satisfy the provisions of Section 11(a) of the Securities Act.

 

    19

     

    

 

 

(b)               
Each Grantor recognizes that the Collateral Agent may be unable to effect a public sale of any or all the Pledged
Stock, by reason of certain prohibitions contained in the Securities Act and applicable state securities laws or otherwise, and
may be compelled to resort to one or more private sales thereof to a restricted group of purchasers which will be obliged to agree,
among other things, to acquire such securities for their own account for investment and not with a view to the distribution or
resale thereof. Each Grantor acknowledges and agrees that any such private sale may result in prices and other terms less favorable
than if such sale were a public sale and, notwithstanding such circumstances, agrees that any such private sale shall be deemed
to have been made in a commercially reasonable manner. The Collateral Agent shall be under no obligation to delay a sale of any
of the Pledged Stock for the period of time necessary to permit the Issuer thereof to register such securities for public sale
under the Securities Act, or under applicable state securities laws, even if such Issuer would agree to do so.

 

(c)               
Each Grantor agrees to use its commercially reasonable efforts to do or cause to be done all such other acts as may
be necessary to make such sale or sales of all or any portion of the Pledged Stock pursuant to this Section 5.5 valid and binding
and in compliance with any and all other applicable law. Each Grantor further agrees that a breach of any of the covenants contained
in this Section 5.5 will cause irreparable injury to the Collateral Agent and the other Notes Secured Parties, that the Collateral
Agent and the other Notes Secured Parties have no adequate remedy at law in respect of such breach and, as a consequence, that
each and every covenant contained in this Section 5.5 shall be specifically enforceable against such Grantor, and such Grantor
hereby waives and agrees not to assert any defenses against an action for specific performance of such covenants except for a defense
that no Event of Default has occurred under the Indenture.

 

5.6              
Subordination. Each Grantor hereby agrees that, upon the occurrence and during the continuance of an Event
of Default, unless otherwise agreed by the Notes Secured Parties, all Indebtedness owing by it to any Subsidiary of the Company
shall be fully subordinated to the indefeasible payment in full in cash of such Notes Obligations.

 

5.7              
Deficiency. Each Grantor shall remain liable for any deficiency if the proceeds of any sale or other disposition
of the Collateral are insufficient to pay its Notes Obligations and the reasonable and documented fees and disbursements of any
attorneys employed by the Collateral Agent or any other Notes Secured Party to collect such deficiency.

 

SECTION
6.      THE COLLATERAL AGENT

 

6.1               Collateral
Agent’s Appointment as Attorney-in-Fact, etc. (a) Each Grantor hereby irrevocably constitutes and appoints the
Collateral Agent and any officer or agent thereof, with full power of substitution, as its true and lawful attorney-in-fact
with full irrevocable power and authority in the place and stead of such Grantor and in the name of such Grantor or in its
own name, solely for the purpose of carrying out the terms of this Agreement, to take any and all appropriate action and to
execute any and all documents and instruments which may be necessary or desirable to accomplish the purposes of this
Agreement, and, without limiting the generality of the foregoing, each Grantor hereby gives the Collateral Agent the power

relating thereto or represented thereby;

 

(2)   
pay or discharge taxes and Liens levied or placed on or threatened against the Collateral, effect any repairs or
any insurance called for by the terms of this Agreement and pay all or any part of the premiums therefor and the costs thereof;

 

(3)   
execute, in connection with any sale provided for in Section 5.4 or 5.5, any indorsements, assignments or other instruments

assign any Copyright, Patent or Trademark (along with the goodwill of the business to which any such Copyright, Patent or Trademark
pertains), throughout the world for such term or terms, on such conditions, and in such manner, as the Collateral Agent shall in
its sole discretion determine; and (8) generally, sell, transfer, pledge and make any agreement with respect to or otherwise deal
with any of the Collateral as fully and completely as though the Collateral Agent were the absolute owner thereof for all purposes,
and do, at the Collateral Agent’s option and such Grantor’s expense, at any time, or from time to time, all acts and
things which the Collateral Agent deems necessary to protect, preserve or realize upon the Collateral and the Collateral Agent’s
and the other Notes Secured Parties’ security interests therein and to effect the intent of this Agreement, all as fully
and effectively as such Grantor might do.

 

Anything in this Section
6.1(a) to the contrary notwithstanding, the Collateral Agent agrees that it will not exercise any rights under the power of attorney
provided for in this Section 6.1(a) (other than pursuant to clause (ii) thereof) unless an Event of Default shall have occurred
and be continuing.

 

(b)               
If any Grantor fails to perform or comply with any of its agreements contained herein, the Collateral Agent, at its
option, but without any obligation so to do, may perform or comply, or otherwise cause performance or compliance, with such agreement.

 

    21

     

    

 

(c)               
The expenses of the Collateral Agent incurred in connection with actions undertaken as provided in this Section 6.1
shall be payable by such Grantor to the Collateral Agent on demand.

 

(d)               
Each Grantor hereby ratifies all that said attorneys shall lawfully do or cause to be done by virtue hereof. All
powers, authorizations and agencies contained in this Agreement are coupled with an interest and are irrevocable until this Agreement
is terminated and the security interests created hereby are released.

 

6.2              
Duty of Collateral Agent. The Collateral Agent’s sole duty with respect to the custody, safekeeping
and physical preservation of the Collateral in its possession, under Section 9-207 of the New York UCC or otherwise, shall be to
deal with it in the same manner as the Collateral Agent deals with similar property for its own account, and no implied covenants
or obligations shall be read into this Agreement against the Collateral Agent. Neither the Collateral Agent, any other Notes Secured
Party nor any of their respective officers, directors, employees or agents shall be liable for failure to demand, collect or realize
upon any of the Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral
upon the request of any Grantor or any other Person or to take any other action whatsoever with regard to the Collateral or any
part thereof. The powers conferred on the Collateral Agent and the other Notes Secured Parties hereunder are solely to protect
the Collateral Agent’s and the other Notes Secured Parties’ interests in the Collateral and shall not impose any duty
upon the Collateral Agent or any other Notes Secured Party to exercise any such powers. The Collateral Agent and the other Notes
Secured Parties shall be accountable only for amounts that they actually receive as a result of the exercise of such powers, and
neither they nor any of their officers, directors, employees or agents shall be responsible to any Grantor for any act or failure
to act hereunder, except for their own gross negligence or willful misconduct.

 

6.3              
Authority of Collateral Agent. Each Grantor acknowledges that the rights and responsibilities of the Collateral
Agent under this Agreement with respect to any action taken by the Collateral Agent or the exercise or non-exercise by the Collateral
Agent of any option, voting right, request, judgment or other right or remedy provided for herein or resulting or arising out of
this Agreement shall, as between the Collateral Agent and the other Notes Secured Parties, be governed by the Indenture and by
such other agreements with respect thereto as may exist from time to time among them, but, as between the Collateral Agent and
the Grantors, the Collateral Agent shall be conclusively presumed to be acting as agent for the Notes Secured Parties with full
and valid authority so to act or refrain from acting, and no Grantor shall be under any obligation, or entitlement, to make any
inquiry respecting such authority.

 

SECTION
7.      MISCELLANEOUS

 

7.1              
Amendments in Writing. None of the terms or provisions of this Agreement may be waived, amended, supplemented
or otherwise modified except in accordance with Article 9 of the Indenture.

 

7.2              
Notices. All notices, requests and demands to or upon the Collateral Agent or any Grantor hereunder shall
be effected in the manner provided for in Section 13.01 of the Indenture; provided that any such notice, request or demand to or
upon any Grantor shall also be addressed to such Grantor at its notice address set forth on Schedule 1.

 

7.3               No
Waiver by Course of Conduct; Cumulative Remedies. Neither the Collateral Agent nor any other Notes Secured Party shall by
any act (except by a written instrument pursuant to Section 7.1), delay, indulgence, omission or otherwise be deemed to have
waived any right or remedy hereunder or to have acquiesced in any Default or Event of Default. No failure to exercise, nor
any delay in exercising, on the part of the Collateral Agent or any other Notes Secured Party, any right, power or privilege
hereunder shall operate as a waiver thereof. No single or partial exercise of any right, power or privilege hereunder shall
preclude any other or further exercise thereof or the exercise of any other right, power or privilege. A waiver by the
Collateral Agent or any other Notes Secured Party of any right or remedy hereunder on any one occasion shall not be construed
as a bar to any right or remedy which the Collateral Agent or such other Notes Secured Party would otherwise have on any
future occasion. The rights and remedies herein provided are cumulative, may be exercised singly or concurrently and are not
exclusive of any other rights or remedies provided by law.

 

    22

     

    

 

7.4       Enforcement
Expenses; Indemnification (a) Each Grantor agrees to pay or reimburse the Collateral Agent and each other Notes Secured Party
for all its costs and expenses incurred hereunder as provided in Article 6 of the Indenture and in collecting against such Grantor
under any Notes Document or otherwise enforcing or preserving any rights under this Agreement and the other Notes Documents to
which such Grantor is a party, including, without limitation, the fees and disbursements of counsel (except for the allocated fees
and expenses of in-house counsel) to the Collateral Agent and each other Notes Secured Party (limited to one counsel to the Collateral
Agent, on behalf of the Notes Secured Parties, and one local counsel to the Collateral Agent, on behalf of the Notes Secured Parties,
in each applicable jurisdiction and, solely in the event of an actual conflict of interest, one additional counsel for each Notes
Secured Party affected by such conflict of interest).

 

(a)               
Without limitation of its indemnification obligations under the other Notes Documents, each Grantor jointly and severally
agrees to indemnify the Collateral Agent and the Notes Secured Parties against, and hold the Collateral Agent harmless from any
and all losses, claims, damages, liabilities and related reasonable out-of-pocket expenses, including the fees, charges and disbursements
of a single counsel for the Collateral Agent or any Notes Secured Party (in addition to one local counsel in each relevant jurisdiction),
incurred by or asserted against the Collateral Agent or any Notes Secured Party by any third party or by any Grantor arising out
of, or in connection with, or as a result of, (i) the execution or delivery of this Agreement, the performance of the respective
parties of their obligations hereunder or the enforcement of this Agreement by the Collateral Agent, or (ii) any actual or prospective
claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory,
whether brought by any third party or by any Grantor and regardless of whether the Collateral Agent or any Notes Secured Party
is a party thereto; provided that such indemnity shall not, as to the Collateral Agent or any such Notes Secured Party,
be available to the extent that such losses, claims, damages, liabilities or related expenses are determined by a court of competent
jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or willful misconduct of the Collateral
Agent or any such Notes Secured Party.

 

(b)               
Each Grantor agrees to pay, and to hold the Collateral Agent and the other Notes Secured Parties harmless from, any
and all liabilities with respect to, or resulting from any delay in paying, any and all stamp, excise, sales or other taxes which
may be payable or determined to be payable with respect to any of the Collateral or in connection with any of the transactions
contemplated by this Agreement.

 

(c)               
Each Grantor agrees to pay, and to hold the Collateral Agent and the other Notes Secured Parties harmless from, any
and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any
kind or nature whatsoever with respect to the execution, delivery, enforcement, performance and administration of this Agreement
to the extent the Company would be required to do so pursuant to the Indenture.

 

(d)               
The agreements in this Section 7.4 shall survive the resignation or removal of the Collateral Agent and the repayment
of the Notes Obligations and all other amounts payable under the Indenture and the other Notes Documents.

 

    23

     

    

 

7.5              
Successors and Assigns. This Agreement shall be binding upon the successors and assigns of each Grantor and

that no Grantor may assign, transfer or delegate any of its rights or obligations under this Agreement without the prior written
consent of the Collateral Agent.

 

7.6              
Counterparts. This Agreement may be executed in one or more counterparts, each of which shall be an original,
but all of which shall constitute but one agreement. Delivery of an executed counterpart of a signature page of this Agreement
by telecopy, emailed pdf. or any other electronic means that reproduces an image of the actual executed signature page shall be
effective as delivery of a manually executed counterpart of this Agreement. The words “execution,” “signed,”
 “signature,” “delivery,” and words of like import in or relating to this Agreement or any document to be
signed in connection with this Agreement shall be deemed to include Electronic Signatures, deliveries or the keeping of records
in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature,
physical delivery thereof or the use of a paper-based recordkeeping system, as the case may be, to the extent and as provided for
in any applicable law, including the Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic
Signatures and Records Act, or any other similar state laws based on the Uniform Electronic Transactions Act. Without limiting
the generality of the foregoing, each of the parties hereto hereby (i) agrees that, for all purposes, including without limitation,
in connection with any workout, restructuring, enforcement of remedies, bankruptcy proceedings or litigation among the parties
hereto, electronic images of this Agreement (including with respect to any signature pages thereto) shall have the same legal effect,
validity and enforceability as any paper original, and (ii) waives any argument, defense or right to contest the validity or enforceability
of this Agreement based solely on the lack of paper original copies of this Agreement, including with respect to any signature
pages thereto. For purposes of this Section 7.6, “Electronic Signature” means an electronic sound, symbol, or process
attached to, or associated with, a contract or other record and adopted by a Person with the intent to sign, authenticate or accept
such contract or record.

 

7.7              
Severability. Any provision of this Agreement which is prohibited or unenforceable in any jurisdiction shall,
as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining
provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable
such provision in any other jurisdiction.

 

7.8              
Section Headings. The Section headings used in this Agreement are for convenience of reference only and are
not to affect the construction hereof or be taken into consideration in the interpretation hereof.

 

7.9              
Integration. This Agreement and the other Notes Documents represent the agreement of the Grantors, the Collateral
Agent and the other Notes Secured Parties with respect to the subject matter hereof and thereof, and there are no promises, undertakings,
representations or warranties by the Collateral Agent or any other Notes Secured Party relative to subject matter hereof and thereof
not expressly set forth or referred to herein or in the other Notes Documents.

 

7.10          
GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE
LAW OF THE STATE OF NEW YORK.

 

7.11          
Additional Grantors. Each Subsidiary of the Company that is required to become a party to this Agreement pursuant
to Section 4.15 of the Indenture shall become a Grantor for all purposes of this Agreement upon execution and delivery by such
Subsidiary of an Assumption Agreement in the form of Annex 1 hereto.

 

    24

     

    

 

7.12          
Releases. The Liens granted under this Agreement shall be released pursuant to Section 11.06 of the Indenture.

 

7.13

the exercise of any right or remedy by the Collateral Agent hereunder shall be subject to the provisions of the applicable Intercreditor
Agreements. In the event of any conflict between the terms of any applicable Intercreditor Agreement and this Agreement, the terms
of the applicable Intercreditor Agreement shall govern and control.

 

(b)       Notwithstanding
anything herein to the contrary, the exercise of any right or remedy by the Collateral Agent hereunder shall be subject to the
