“Section 10.10 Relative Rights;
Intercreditor Agreements.

 

(a) The Issuer and the Note Guarantor
each agree, and each Holder by accepting a Note agrees, that notwithstanding the date, time, method, manner or order of grant,
attachment or perfection of any Liens securing the Secured Obligations or any Senior Priority Liens securing the Designated Senior
Claims or any Liens securing Limited Secured Acquisition Debt, and notwithstanding any defect or deficiencies in, or failure to
perfect or lapse in perfection of, or avoidance as a fraudulent conveyance or otherwise of, any such Liens, the security interest
in the Collateral securing the Secured Obligations shall be junior in priority to all Liens securing any Designated Senior Claims
and Limited Secured Acquisition Debt. The foregoing lien subordination is for the benefit of and enforceable by holders of Designated
Senior Claims and Limited Secured Acquisition Debt. If requested by the holder of any Designated Senior Claim or Limited Secured
Acquisition Debt or a representative of such a holder, the Trustee and the Collateral Agent each shall execute the applicable Junior
Lien or Limited Secured Acquisition Debt Intercreditor Agreement. The applicable Junior Lien or Limited Secured Acquisition Debt
Intercreditor Agreement defines the relative rights of holders of the Subordinated Liens and the holders of the Senior Priority
Liens and holders of the liens securing Limited Secured Acquisition Debt that will exist upon

 

     

     

    

execution of the applicable Junior Lien or Limited Secured
Acquisition Debt Intercreditor Agreement. Notwithstanding anything to the contrary contained herein, in the Notes or in any Security
Documents, upon execution of the applicable Junior Lien or Limited Secured Acquisition Debt Intercreditor Agreement, any Subordinated
Liens securing the Secured Obligations, and the exercise of any right or remedy with respect thereto, will be subject to the provisions
of the applicable Junior Lien or Limited Secured Acquisition Debt Intercreditor Agreement. In the event of any conflict between
the terms of, on the one hand, the applicable Junior Lien or Limited Secured Acquisition Debt Intercreditor Agreement and, on the
other hand, any Note, this Indenture or any Security Document, upon execution of the applicable Junior Lien or Limited Secured
Acquisition Debt Intercreditor Agreement the terms of the applicable Junior Lien or Limited Secured Acquisition Debt Intercreditor
Agreement shall govern and control. Each Holder, by its acceptance of any Note, irrevocably agrees to be bound by the provisions
of the applicable Junior Lien or Limited Secured Acquisition Debt Intercreditor Agreement and each Holder by its acceptance of
any Note hereby directs, and the Trustee and Collateral Agent shall and are hereby authorized, to enter into the applicable Junior
Lien or Limited Secured Acquisition Debt Intercreditor Agreement. Each Holder by its acceptance of the Notes agrees that it will
be bound by, and will take no action contrary to, the provisions of the applicable Junior Lien or Limited Secured Acquisition Debt
Intercreditor Agreement. The foregoing provisions are intended as an inducement to the present and future holders of the Designated
Senior Claims and Limited Secured Acquisition Debt and such holders are intended third party beneficiaries of the applicable Junior
Lien or Limited Secured Acquisition Debt Intercreditor Agreement. Each Note and each Security Document shall bear a conspicuous
legend that the Liens securing the Secured Obligations under this Indenture, and rights and remedies related thereto, are subordinated
pursuant to the terms of the applicable Junior Lien or Limited Secured Acquisition Debt Intercreditor Agreement, in each case in
the manner set forth therein.

 

(b)       The
Issuer and the Note Guarantor each agree, and each Holder by accepting a Note agrees, that notwithstanding the date, time, method,
manner or order of grant, attachment or perfection of any Liens securing the Secured Obligations or any Liens securing the Pari
Passu Lien Obligations, and notwithstanding any defect or deficiencies in, or failure to perfect or lapse in perfection of, or
avoidance as a fraudulent conveyance or otherwise of, any such Liens, the security interest in the Collateral securing the Secured
Obligations shall be pari passu in priority with all Liens securing any Pari Passu Lien Obligations. The foregoing is for the benefit
of and enforceable by holders of Pari Passu Lien Obligations. The Trustee and the Collateral Agent each shall execute the Pari
Passu Lien Intercreditor Agreement. The Pari Passu Lien Intercreditor Agreement defines the relative rights of holders of the Liens
securing the Secured Obligations and the holders of the Liens securing the Pari Passu Lien Obligations. Notwithstanding anything
to the contrary contained herein, in the Notes or in any Security Documents, upon execution of the Pari Passu Lien Intercreditor
Agreement, any Liens securing the Secured Obligations, and the exercise of any

 

     

     

    

right or remedy with respect thereto, will be subject
to the provisions of the Pari Passu Lien Intercreditor Agreement. In the event of any conflict between the terms of, on the one
hand, the Pari Passu Lien Intercreditor Agreement and, on the other hand, any Note, this Indenture or any Security Document, upon
execution of the Pari Passu Lien Intercreditor Agreement, the terms of the Pari Passu Lien Intercreditor Agreement shall govern
and control. Each Holder, by its acceptance of any Note, irrevocably agrees to be bound by the provisions of the Pari Passu Lien
Intercreditor Agreement and each Holder by its acceptance of any Note hereby directs, and the Trustee and Collateral Agent shall
and are hereby authorized, to enter into the Pari Passu Lien Intercreditor Agreement. Each Holder by its acceptance of the Notes
agrees that it will be bound by, and will take no action contrary to, the provisions of the Pari Passu Lien Intercreditor Agreement.
The foregoing provisions are intended as an inducement to the present and future holders of the Pari Passu Lien Obligations and
such holders are intended third party beneficiaries of the Pari Passu Lien Intercreditor Agreement.

 

(c)       The
Issuer and each issuer of “Finance Debt” as described in Section 4.10(b)(9) of the indenture for the New Notes (the
“Acquired Subsidiary”) agrees, and each Holder by accepting a Note agrees, that notwithstanding the date, time, method,
manner or order of grant, attachment or perfection of any Liens securing the Obligations of such Acquired Subsidiary under the
guarantee of the Notes (the “Acquired Subsidiary Secured Obligations”) in the form attached hereto as Exhibit J (the
“Acquired Subsidiary Guarantee”) or any Liens securing such “Finance Debt”, and notwithstanding any defect
or deficiencies in, or failure to perfect or lapse in perfection of, or avoidance as a fraudulent conveyance or otherwise of, any
such Liens, the security interest in the Collateral securing the Acquired Subsidiary Secured Obligations, pursuant to the pledge
and security agreement in the form attached hereto as Exhibit K, shall be senior in priority with all Liens securing any such “Finance
Debt”. For the avoidance of doubt, the Acquired Subsidiary Secured Obligations and the Liens on the Collateral securing the
Acquired Subsidiary Secured Obligations are limited to the amount of certain cash transferred or cash payments made pursuant to
Section 4.10(b)(9)(A)(B) and (D) of the indenture for the New Notes in exchange for the Equity Interests of the Acquired Subsidiary.
The foregoing is for the benefit of and enforceable by each Holder of the Notes. The Trustee and the Collateral Agent each shall
execute the Senior Lien Intercreditor Agreement. The Senior Lien Intercreditor Agreement defines the relative rights of holders
of the Liens securing the Acquired Subsidiary Secured Obligations and the holders of the Liens securing the “Finance Debt”.
Notwithstanding anything to the contrary contained herein, in the Notes or in any Security Documents, upon execution of the Senior
Lien Intercreditor Agreement, any Liens securing the Acquired Subsidiary Secured Obligations, and the exercise of any right or
remedy with respect thereto, will be subject to the provisions of the Senior Lien Intercreditor Agreement. In the event of any
conflict between the terms of, on the one hand, the Senior Lien Intercreditor Agreement and, on the other hand, any Note, this
Indenture or any Security Document, upon execution of the Senior Lien Intercreditor Agreement, the terms of the Senior Lien Intercreditor
Agreement shall govern and control.

 

     

     

    

Each Holder, by its acceptance of any Note, irrevocably
agrees to be bound by the provisions of the Senior Lien Intercreditor Agreement and each Holder by its acceptance of any Note hereby
directs, and the Trustee and Collateral Agent shall and are hereby authorized, to enter into the Senior Lien Intercreditor Agreement,
the guarantee provided by the Acquired Subsidiary and the related pledge and security agreement at the times such corresponding
documents are executed and delivered in accordance with the provisions of the indenture for the New Notes. Each Holder by its acceptance
of the Notes agrees that it will be bound by, and will take no action contrary to, the provisions of the Senior Lien Intercreditor
Agreement. The foregoing provisions are intended as an inducement to the present and future Holders of the Notes and such Holders
are intended third party beneficiaries of the Senior Lien Intercreditor Agreement.”.

such asset or property or the applicable Junior Lien Collateral Agent otherwise expressly declines to accept a Lien on such asset
or property (any such prohibited or declined Lien with respect to a particular Series of Junior Lien Obligations, a “Junior
Lien Declined Lien”).

 

If any Junior Lien Representative, any Junior
Lien Collateral Agent or any Junior Lien Claimholder shall hold any Lien on any assets or property of the Company securing any

Representative, Senior Lien Collateral Agent and Senior Lien Claimholders shall be deemed to hold and have held such Lien for the
benefit of each Junior Lien Representative, Junior Lien Collateral Agent and the other Junior Lien Claimholders (subject to the
priorities set forth herein), other than any Junior Lien Claimholders whose Junior Lien Documents prohibit them from taking such
Liens, as security for the Junior Lien Obligations. To the extent that the foregoing provisions are not complied with for any reason,

the Junior Lien Claimholders. The provisions of this Agreement are intended solely to govern the respective Lien priorities as
between the Senior Lien Claimholders on the one hand and the Junior Lien Claimholders on the other hand and such provisions shall
not impose on the Senior Lien Representatives, Senior Lien Collateral Agents, the Senior Lien Claimholders, the Junior Lien Representatives,
the Junior Lien Collateral Agents, the Junior Lien Claimholders or any agent or trustee therefor any obligations in respect of
the disposition of proceeds of any Collateral which would conflict with prior-perfected claims therein in favor of any other Person

Obligations may be modified, extended or amended from time to time, and that the aggregate amount of the Senior Lien Obligations
may be increased, replaced or refinanced, in each event, without notice to or consent by the Junior Lien Claimholders and without

if, notwithstanding the expiration of the Standstill Period, any Senior Lien Representative, any Senior Lien Collateral Agent or
any applicable Senior Lien Claimholder(s) shall have commenced and is pursuing a Collateral Enforcement Action or other exercise
of its or their rights or remedies in each case with respect to all or any material portion of

 

    	 	15	 

     

    

the Collateral (prompt written notice of such exercise
to be given to the Junior Lien Representative);

 

(2)    
will not contest, protest or object to (i) any foreclosure proceeding or action brought by any Senior Lien Representative,
any Senior Lien Collateral Agent or any Senior Lien Claimholder or (ii) any other exercise by any Senior Lien Representative,
any Senior Lien Collateral Agent or any Senior Lien Claimholder of any rights and remedies relating to the Collateral under the
Senior Lien Documents or otherwise (including any Collateral Enforcement Action initiated by or supported by any Senior Lien Representative,
any Senior Lien Collateral Agent or any Senior Lien Claimholder); and

 

(3)    
subject to their rights under clause (a)(1) above will not object to the forbearance by any Senior Lien Representative,
any Senior Lien Collateral Agent or any Senior Lien Claimholder from bringing or pursuing any foreclosure proceeding or action
or any other exercise of any rights or remedies relating to the Collateral, in each case so long as any proceeds received by any
Senior Lien Representative in excess of those necessary to achieve a Discharge of Senior Lien Obligations are distributed in accordance
with Section 5.1 hereof and applicable law.

 

(b)    
Until the Discharge of Senior Lien Obligations has occurred, whether or not any Insolvency or Liquidation Proceeding has
been commenced by or against the Company, subject to Section 4.1(a)(1), the Senior Lien Representatives, the Senior
Lien Collateral Agents and the Senior Lien Claimholders shall have the exclusive right to (i) commence and maintain a Collateral
Enforcement Action or otherwise enforce rights, exercise remedies (including set-off, recoupment and the right to credit bid their
debt, except that Junior Lien Representatives shall have the credit bid rights set forth in Section 4.1(c)(6)), and
(ii) subject to Section 5.3, make determinations regarding the release, disposition, or restrictions with respect
to the Collateral without any consultation with or the consent of any Junior Lien Representative, any Junior Lien Collateral Agent
or any other Junior Lien Claimholder; provided that, in each case, any proceeds received by any Senior Lien Representative
in excess of those necessary to achieve a Discharge of Senior Lien Obligations are distributed in accordance with Section 5.1
hereof and applicable law. In commencing or maintaining any Collateral Enforcement Action or otherwise exercising rights and remedies
with respect to the Collateral, the Senior Lien Representatives, Senior Lien Collateral Agents and the Senior Lien Claimholders
may enforce the provisions of the Senior Lien Documents and exercise remedies thereunder, all in such order and in such manner
as they may determine in the exercise of their sole discretion in compliance with any applicable law and without consultation with
any Junior Lien Representative, any Junior Lien Collateral Agent or any other Junior Lien Claimholder and regardless of whether
any such exercise is adverse to the interest of any Junior Lien Claimholder. Such exercise and enforcement shall include the rights
of an agent appointed by them to sell or otherwise dispose of Collateral upon foreclosure, to incur expenses in connection with
such sale or disposition, and to exercise all the rights and remedies of a secured creditor under the UCC and under Bankruptcy
Law of any applicable jurisdiction.

 

(c)    
Notwithstanding the foregoing, any Junior Lien Representative, any Junior Lien Collateral Agent, in accordance with any
relevant Junior Lien Security Document, and any other Junior Lien Claimholder may:

 

(1)    
file a claim or statement of interest with respect to the Junior Lien Obligations; provided that an Insolvency or
Liquidation Proceeding has been commenced by or against the Company;

 

(2)    
take any action not adverse to the priority status of the Liens on the Collateral securing the Senior Lien Obligations,
or the rights of any Senior Lien Representative, any Senior Lien Collateral Agent or the Senior Lien Claimholders to exercise remedies
in respect thereof, in order to create, perfect, preserve or protect its Lien on the Collateral;

 

(3)    
file any necessary responsive or defensive pleadings in opposition to any motion, claim, adversary proceeding or other pleading
made by any person objecting to or otherwise

 

    	 	16	 

     

    

seeking the disallowance of the claims of the Junior
Lien Claimholders, including any claims secured by the Collateral, if any, in each case in accordance with the terms of this Agreement;

 

(4)    
vote on any plan of reorganization, arrangement, compromise or liquidation, file any proof of claim, make other filings
and make any arguments and motions that are, in each case, in accordance with the terms of this Agreement, with respect to the
Junior Lien Obligations and the Collateral; provided that no filing of any claim or vote, or pleading related to such claim
or vote, to accept or reject a disclosure statement, plan of reorganization, arrangement, compromise or liquidation, or any other
document, agreement or proposal similar to the foregoing by any Junior Lien Representative, any Junior Lien Collateral Agent or
any other Junior Lien Claimholder, may be inconsistent with the provisions of this Agreement;

 

(5)    
exercise any of its rights or remedies with respect to the Collateral after the termination of the Standstill Period to
the extent permitted by Section 4.1(a)(1); and

 

(6)    
bid for or purchase Collateral at any public, private or judicial foreclosure upon such Collateral initiated by any Senior
Lien Representative, any Senior Lien Collateral Agent or any other Senior Lien Claimholder, or any sale of Collateral during an
Insolvency or Liquidation Proceeding; provided that such bid may not include a “credit bid” in respect of any
Junior Lien Obligations unless the cash proceeds of such bid are otherwise sufficient to cause the Discharge of Senior Lien Obligations.

 

Each Junior Lien Representative and each
Junior Lien Collateral Agent, on behalf of itself and each other Junior Lien Claimholder represented by it, agrees that it will
not take or receive any Collateral or any proceeds of Collateral in connection with the exercise of any right or remedy (including
set-off and recoupment) with respect to any Collateral in its capacity as a creditor, unless and until the Discharge of Senior
Lien Obligations has occurred, except in connection with any foreclosure that is expressly permitted by Section 4.1(a)(1)
to pursue after the expiration of the Standstill Period to the extent such Junior Lien Representative or such Junior Lien Collateral
Agent and Junior Lien Claimholders represented by it are permitted to retain the proceeds thereof in accordance with Section 5.2
of this Agreement. Without limiting the generality of the foregoing, unless and until the Discharge of Senior Lien Obligations
has occurred, except as expressly provided in Sections 4.1(a), 6.3(b) and this Section 4.1(c), the
sole right of the Junior Lien Representatives, the Junior Lien Collateral Agents and the other Junior Lien Claimholders with respect
to the Collateral is to hold a Lien on the Collateral pursuant to the Junior Lien Collateral Documents for the period and to the
extent granted therein and to receive a share of the proceeds thereof, if any, after the Discharge of Senior Lien Obligations has
occurred.

 

(d)    
Subject to Sections 4.1(a) and (c) and Section 6.3(b):

 

(1)    
each Junior Lien Representative and each Junior Lien Collateral Agent, for itself and on behalf of each other Junior Lien
Claimholder represented by it, agrees that such Junior Lien Representative or such Junior Lien Collateral Agent and such Junior
Lien Claimholders represented by it will not take any action that would hinder any exercise of remedies under the Senior Lien Documents
or that is otherwise prohibited hereunder, including any sale, lease, exchange, transfer or other disposition of the Collateral,
whether by foreclosure or otherwise;

 

(2)    
each Junior Lien Representative and each Junior Lien Collateral Agent, for itself and on behalf of each other Junior Lien
Claimholder represented by it, hereby waives any and all rights such Junior Lien Representative or such Junior Lien Collateral
Agent and such Junior Lien Claimholders represented by it may have as a junior lien creditor or otherwise to object to the manner
in which any Senior Lien Representative, any Senior Lien Collateral Agent or any other Senior Lien Claimholder seeks to enforce
or collect the Senior Lien Obligations or Liens securing the Senior Lien Obligations granted in any of the Senior Lien Collateral
undertaken in accordance with this Agreement, regardless of whether any action or failure to act by or on behalf of any Senior
Lien Representative, any Senior Lien Collateral Agent or any other Senior Lien Claimholder is adverse to the interest of any Junior
Lien Claimholder; and

 

    	 	17	 

     

    

(3)    
each Junior Lien Representative and each Junior Lien Collateral Agent, for itself and on behalf of each other Junior Lien
Claimholder represented by it, hereby acknowledges and agrees that no covenant, agreement or restriction contained in any Junior
Lien Documents (other than this Agreement) shall be deemed to restrict in any way the rights and remedies of any Senior Lien Representative,
any Senior Lien Collateral Agent or any other Senior Lien Claimholder with respect to the Collateral as set forth in this Agreement
and the Senior Lien Documents.

 

(e)    
Except as specifically set forth in this Agreement, Article II of the Initial Junior Lien Indentures and the Note Subordination
Agreements, the Junior Lien Representatives, the Junior Lien Collateral Agents and the other Junior Lien Claimholders may exercise
rights and remedies as unsecured creditors against the Company that has guaranteed or granted Liens to secure the Junior Lien Obligations
in accordance with the terms of the Junior Lien Documents and applicable law (other than initiating or joining in an involuntary
case or proceeding under any Insolvency or Liquidation Proceeding with respect to the Company); provided that in the event
that any Junior Lien Claimholder becomes a judgment Lien creditor in respect of Collateral as a result of its enforcement of its
rights as an unsecured creditor with respect to the Junior Lien Obligations, such judgment Lien shall be subject to the terms of
this Agreement for all purposes (including in relation to the Senior Lien Obligations) in the same manner as the other Liens securing
the Junior Lien Obligations are subject to this Agreement.

 

(f)     
Except as specifically set forth in Sections 4.1(a) and (d), and without limiting Article II of the Initial
Junior Lien Indentures or the Note Subordination Agreements, nothing in this Agreement shall prohibit the receipt by any Junior
Lien Representative, any Junior Lien Collateral Agent or any other Junior Lien Claimholder of the required payments of interest,
principal and other amounts owed in respect of the Junior Lien Obligations so long as such receipt is not the direct or indirect
result of the exercise by any Junior Lien Representative, any Junior Lien Collateral Agent or any other Junior Lien Claimholder
of rights or remedies as a secured creditor (including set-off and recoupment) or enforcement in contravention of this Agreement
of any Lien held by any of them or as a result of any other violation by any Junior Lien Claimholder of the express terms of this
Agreement. Nothing in this Agreement impairs or otherwise adversely affects any rights or remedies any Senior Lien Representative,
any Senior Lien Collateral Agent or other Senior Lien Claimholder may have with respect to the Senior Lien Collateral.

 

4.2   
Actions Upon Breach; Specific Performance. If any Junior Lien Claimholder, in contravention of the terms of this
Agreement, in any way takes, attempts to or threatens to take any action with respect to the Collateral (including any attempt
to realize upon or enforce any remedy with respect to this Agreement), or fails to take any action required by this Agreement,
this Agreement shall create an irrebutable presumption and admission by such Junior Lien Claimholder that relief against such Junior
Lien Claimholder by injunction, specific performance and/or other appropriate equitable relief is necessary to prevent irreparable
harm to the Senior Lien Claimholders, it being understood and agreed by each Junior Lien Representative and each Junior Lien Collateral
Agent, on behalf of each Junior Lien Claimholder represented by it, that (i) the Senior Lien Claimholders’ damages from
actions of any Junior Lien Claimholder may at that time be difficult to ascertain and may be irreparable and (ii) each Junior
Lien Claimholder waives any defense that either or both the Company and the Senior Lien Claimholders cannot demonstrate either
or both damage and be made whole by the awarding of damages. Each of the Senior Lien Representatives and Senior Lien Collateral
Agents may demand specific performance of this Agreement. Each Junior Lien Representative and each Junior Lien Collateral Agent,
on behalf of itself and each other Junior Lien Claimholder represented by it, hereby irrevocably waives any defense based on the
adequacy of a remedy at law and any other defense which might be asserted to bar the remedy of specific performance in any action
which may be brought by any Senior Lien Representative, any Senior Lien Collateral Agent or any other Senior Lien Claimholder.
No provision of this Agreement shall constitute or be deemed to constitute a waiver by any Senior Lien Representative or any Senior
Lien Collateral Agent on behalf of itself and each other Senior Lien Claimholder represented by it, of any right to seek damages
from any Person in connection with any breach or alleged breach of this Agreement.

 

		Section 5.	Payments.

 

5.1   
Application of Proceeds. So long as the Discharge of Senior Lien Obligations has not occurred, whether or not any
Insolvency or Liquidation Proceeding has been commenced by or against the Company, any

 

    	 	18	 

     

    

Collateral or any proceeds thereof, Restricted Assets or any
proceeds thereof or Sale Proceeds received in connection with any Collateral Enforcement Action or other exercise of remedies by
any Senior Lien Representative, any Senior Lien Collateral Agent or any Senior Lien Claimholder, shall be applied by the Senior
Lien Collateral Agents or the Senior Lien Representatives, as applicable, to the Senior Lien Obligations in such order as specified
in the relevant Senior Lien Documents and, if then in effect, the Senior Lien Intercreditor Agreement; provided, that any non-cash
Collateral or non-cash proceeds may be held by the applicable Senior Lien Collateral Agent as Collateral unless the failure to
apply such amounts would be commercially unreasonable. Upon the Discharge of Senior Lien Obligations, each Senior Lien Collateral
Agent shall (x) unless a Discharge of Junior Lien Obligations has already occurred, deliver any remaining proceeds of Collateral,
Restricted Assets and Sale Proceeds held by it to the Junior Lien Collateral Agent, to be applied by the Junior Lien Collateral
Agent and the other Junior Lien Collateral Agents or Junior Lien Representatives, as applicable, to the applicable Junior Lien
Obligations in such order as specified in the applicable Junior Lien Documents and (y) if a Discharge of Junior Lien Obligations
has already occurred, deliver such proceeds of Collateral, Restricted Assets and Sale Proceeds to the Company or to whomever may
be lawfully entitled to receive the same. Without limiting the generality of the foregoing, it is the intention of the parties
hereto that no amount of any Sale Proceeds will in any event be allocated to any Restricted Assets, and no Junior Lien Representative,
Junior Lien Collateral Agent or other Junior Lien Claimholder will, in any forum (including in any Insolvency or Liquidation Proceeding),
assert that any amount of any Sale Proceeds should be allocated to any Restricted Assets.

 

5.2   
Payments Over.

 

(a)    
So long as the Discharge of Senior Lien Obligations has not occurred, whether or not any Insolvency or Liquidation Proceeding
has been commenced by or against the Company, any Collateral or any proceeds thereof, Restricted Assets or proceeds thereof and
all Sale Proceeds (including assets or proceeds subject to Liens referred to in the second to last paragraph of Section 3.3
and any assets or proceeds subject to Liens that have been avoided or otherwise invalidated) received by any Junior Lien Representative,
Junior Lien Collateral Agent or any other Junior Lien Claimholder in connection with any Collateral Enforcement Action or other
exercise of any right or remedy relating to the Collateral or the Restricted Assets, in all cases shall be segregated and held
in trust and forthwith paid over to the Designated Senior Lien Collateral Agent for the benefit of the Senior Lien Claimholders
in the same form as received, with any necessary endorsements (which endorsements shall be without recourse and without any representations
or warranties) or as a court of competent jurisdiction may otherwise direct. The Designated Senior Lien Collateral Agent is hereby
authorized to make any such endorsements as agent for the Junior Lien Representatives, Junior Lien Collateral Agents or any such
other Junior Lien Claimholder. This authorization is coupled with an interest and is irrevocable until the Discharge of Senior
Lien Obligations.

 

(b)    
So long as the Discharge of Senior Lien Obligations has not occurred, if in any Insolvency or Liquidation Proceeding any
Junior Lien Representative, any Junior Lien Collateral Agent or any other Junior Lien Claimholder shall receive any distribution
of money or other property in respect of the Collateral, Restricted Assets or Sale Proceeds (including any assets or proceeds subject
to Liens that have been avoided or otherwise invalidated), such money or other property shall be segregated and held in trust and
forthwith paid over to the Designated Senior Lien Collateral Agent for the benefit of the Senior Lien Claimholders in the same
form as received, with any necessary endorsements (which endorsements shall be without recourse and without any representations
or warranties). Any Lien received by any Junior Lien Representative, any Junior Lien Collateral Agent or any other Junior Lien
Claimholder in respect of any of the Junior Lien Obligations in any Insolvency or Liquidation Proceeding shall be subject to the
terms of this Agreement.

 

5.3   
Releases.

 

(a)    
If in connection with any Collateral Enforcement Action by any Senior Lien Representative or any Senior Lien Collateral
Agent or any other exercise of any Senior Lien Representative’s or any Senior Lien Collateral Agent’s remedies in respect
of the Collateral, in each case prior to the Discharge of Senior Lien Obligations, such Senior Lien Collateral Agent, for itself
or on behalf of any of the Senior Lien Claimholders represented by it, releases any of its Liens on any part of the Collateral,
then the Liens, if any, of each Junior Lien Collateral Agent, for itself or for the benefit of the Junior Lien Claimholders, on
such

 

    	 	19	 

     

    

Collateral, shall be automatically, unconditionally
and simultaneously released. Each Junior Lien Representative and each Junior Lien Collateral Agent, for itself or on behalf of
any Junior Lien Claimholder represented by it, shall, within a reasonable time following such request, execute and deliver to the
Senior Lien Representatives, Senior Lien Collateral Agents or the Company, such termination statements, releases and other documents
as any Senior Lien Representative, Senior Lien Collateral Agent or the Company may request in writing to effectively confirm the
foregoing releases, provided that the Junior Lien Representative and Junior Lien Collateral Agent shall not be required
to take any action if such actions would violate applicable law or court order.

 

(b)    
If in connection with any sale, lease, exchange, transfer or other disposition of any Collateral by the Company (collectively,
a “Disposition”) permitted under the terms of the Senior Lien Documents and not expressly prohibited under the
terms of the Junior Lien Documents (other than in connection with a Collateral Enforcement Action or other exercise of any one
or more Senior Lien Representative’s and Senior Lien Collateral Agent’s remedies in respect of the Collateral, which
shall be governed by Section 5.3(a) above above), any Senior Lien Collateral Agent, for itself or on behalf of any
Senior Lien Claimholder represented by it, releases any of its Liens on any part of the Collateral, other than (A) in connection
with, or following, the Discharge of Senior Lien Obligations or (B) after the occurrence and during the continuance of any
Event of Default under (and as defined in) any Junior Lien Documents, then the Liens, if any, of each Junior Lien Collateral Agent,
for itself or for the benefit of the Junior Lien Claimholders represented by it, on such Collateral shall be automatically, unconditionally
and simultaneously released. Each Junior Lien Representative and each Junior Lien Collateral Agent, for itself and on behalf of
each other Junior Lien Claimholder represented by it, shall, promptly execute and deliver to the Senior Lien Representatives, the
Senior Lien Collateral Agents or the Company such termination statements, releases and other documents as any Senior Lien Representative,
Senior Lien Collateral Agent or the Company may request to effectively confirm such release, provided that the Junior Lien
Representative and Junior Lien Collateral Agent shall not be required to take any action if such actions would violate applicable
law or court order.

 

(c)    
Until the Discharge of Senior Lien Obligations occurs, each Junior Lien Representative and each Junior Lien Collateral Agent,
for itself and on behalf of each other Junior Lien Claimholder represented by it, hereby irrevocably constitutes and appoints the
Designated Senior Lien Collateral Agent and any officer or agent of the Designated Senior Lien Collateral Agent, 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
Junior Lien Representative, such Junior Lien Collateral Agent and such Junior Lien Claimholders or in the Designated Senior Lien
Collateral Agent’s own name, from time to time in the Designated Senior Lien Collateral Agent’s discretion, for the
purpose of carrying out the terms of this Section 5.3, to take any and all appropriate action and to execute any and
all documents and instruments which may be necessary to accomplish the purposes of this Section 5.3, including any
endorsements or other instruments of transfer or release. This power is coupled with an interest and is irrevocable until the Discharge
of Senior Lien Obligations.

 

(d)    
Until the Discharge of Senior Lien Obligations occurs, to the extent that any Senior Lien Collateral Agent, any Senior Lien
Representative or Senior Lien Claimholders (i) has released any Lien on Collateral and any such Liens are later reinstated
or (ii) obtains any new Liens from the Company, then each Junior Lien Collateral Agent, for itself and for the Junior Lien
Claimholders represented by it, shall be granted a Lien on any such Collateral (except to the extent such Lien represents a Junior
Lien Declined Lien with respect to the Junior Lien Debt represented by such Junior Lien Collateral Agent), subject to the lien
subordination provisions of this Agreement, and each Junior Lien Representative, for itself and for the Junior Lien Claimholders
represented by it, shall be granted an additional lien.

 

5.4   
Insurance. Unless and until the Discharge of Senior Lien Obligations has occurred, the Senior Lien Representatives,
the Senior Lien Collateral Agents and the other Senior Lien Claimholders shall have the sole and exclusive right, subject to the
rights of the Company under the Senior Lien Documents, to adjust settlement for any insurance policy covering the Collateral in
the event of any loss thereunder and to approve any award granted in any condemnation or similar proceeding (or any deed in lieu
of condemnation) affecting the Collateral. Subject to the rights of the Company under the Senior Lien Documents, all proceeds of
any such policy and any such award (or

 

    	 	20	 

     

    

any payments with respect to a deed in lieu of condemnation)
if in respect of the Collateral shall be applied in the order of priority set forth in Section 5.1. Until the Discharge of
Senior Lien Obligations has occurred, if any Junior Lien Representative, any Junior Lien Collateral Agent or any other Junior Lien
Claimholder shall, at any time, receive any proceeds of any such insurance policy or any such award or payment in contravention
of this Agreement, then it shall segregate and hold in trust and forthwith pay such proceeds over to the Designated Senior Lien
Collateral Agent in accordance with the terms of Section 5.2.

 

5.5   
Amendments to Senior Lien Documents and Junior Lien Documents.

 

(a)    
The Senior Lien Documents of any Series may be amended, restated, amended and restated, supplemented or otherwise modified
from time to time in accordance with their terms and the Senior Lien Claims of any Series may be Refinanced subject to Section 5.8
and Section 8.7, in each case, without notice to, or the consent of, any Junior Lien Representative, any Junior Lien
Collateral Agent or any other Junior Lien Claimholder, all without affecting the lien subordination or other provisions of this
Agreement; provided that any such amendment, supplement or modification or Refinancing is not inconsistent with the terms
of this Agreement and, in the case of a Refinancing, the holders of such Refinancing debt or their agent bind themselves in a writing
addressed to each Junior Lien Collateral Agent to the terms of this Agreement.

 

(b)    
The Junior Lien Documents may be amended, restated, amended and restated, supplemented or otherwise modified from time to
time in accordance with their terms and the Junior Lien Debt of any Series may be Refinanced in full but not in part subject to
Section 5.8 and Section 8.7, in each case, without notice to, or the consent of, any Senior Lien Representative,
any Senior Lien Collateral Agent or any other Senior Lien Claimholder, all without affecting the lien subordination or other provisions
of this Agreement, provided that any such amendment, restatement, supplement or modification or Refinancing is not inconsistent
with the terms of this Agreement and, in the case of any Refinancing, the holders of such Refinancing debt or their agent bind
themselves in a writing addressed to each Senior Lien Collateral Agent to the terms of this Agreement; and provided further that
any such amendment, restatement, supplement, modification or Refinancing shall not, without the consent of each Senior Lien Representative:

 

(1)    
increase the then-outstanding principal amount of the Junior Lien Debt of that Series, provided, that the foregoing shall
not restrict any increases in principal resulting from any “payment in kind”;

 

(2)    
increase the “Applicable Margin” or similar component of the interest rate or yield provisions applicable to
the Indebtedness outstanding under the Junior Lien Documents of that Series in a manner that would result in the total yield thereon
to exceed by more than [3]% per annum the total yield on Indebtedness thereunder as in effect on the date such Indebtedness
became Junior Lien Debt (excluding increases resulting from the accrual of interest at the default rate);

 

(3)    
amend or otherwise modify any “Default” or “Event of Default” (as each such term is defined in the
Junior Lien Documents for that Series) thereunder in a manner adverse to the loan parties thereunder;

 

(4)    
accelerate any date upon which a scheduled payment of principal or interest is due, or otherwise decrease the weighted average
life to maturity;

 

(5)    
modify (or undertake any action having the effect of a modification of) the mandatory prepayment provisions of the Junior
Lien Documents for that Series in a manner adverse to the Senior Lien Claimholders; or

 

(6)    
increase materially the obligations of the obligor thereunder or confer any additional material rights of the Junior Lien
Claimholders (or a representative on their behalf) which would be adverse to any Senior Lien Claimholders.

 

    	 	21	 

     

    

(c)    
In the event any Senior Lien Collateral Agent or the applicable Senior Lien Claimholders and the Company enter into any
amendment, waiver or consent in respect of any of the Senior Lien Collateral Documents for the purpose of adding to, or deleting
from, or waiving or consenting to any departures from any provisions of, any Senior Lien Collateral Document or changing in any
manner the rights of the applicable Senior Lien Collateral Agent, Senior Lien Claimholders, or the Company thereunder, then such
amendment, waiver or consent shall apply automatically to any comparable provision of a Junior Lien Collateral Document without
the consent of any Junior Lien Representative, Junior Lien Collateral Agent or other Junior Lien Claimholder and without any action
by any Junior Lien Representative, any Junior Lien Collateral Agent, any other Junior Lien Claimholder, or the Company, provided
that:

 

(1)    
no such amendment, waiver or consent shall have the effect of:

 

(A)   
removing assets subject to the Lien of the Junior Lien Collateral Documents, except to the extent that a release of such
Lien is permitted or required by Section 5.3 and provided that there is a corresponding release of the Liens securing
any Senior Lien Obligations;

 

(B)   
imposing duties on any Junior Lien Collateral Agent or any Junior Lien Representative without its consent;

 

(C)   
permitting other Liens on the Collateral not permitted under the terms of the Junior Lien Documents or Section 6
hereof; or

 

(D)   
being prejudicial to the interests of the Junior Lien Claimholders to a materially greater extent than the Senior Lien Claimholders
(other than by virtue of their relative priority and the rights and obligations hereunder); and

 

(2)    
notice of such amendment, waiver or consent shall have been given to each Junior Lien Collateral Agent within ten (10) Business
Days after the effective date of such amendment, waiver or consent.

 

5.6   
Confirmation of Subordination in Junior Lien Collateral Documents. The Company agrees that each Junior Lien Collateral
Document shall include the following language (or language to similar effect approved by the Designated Senior Lien Collateral
Agent):

 

“Notwithstanding anything herein to the contrary,
the lien and security interest granted to the [collateral agent] pursuant to this Agreement and the exercise of any right or remedy
by the [collateral agent] hereunder are subject to the provisions of the Junior Lien Subordination and Intercreditor Agreement,
dated as of [                    ]
(as amended, restated, amended and restated, supplemented or otherwise modified from time to time, the “Junior Lien Subordination
and Intercreditor Agreement”), among [                    ],
as Initial Senior Lien Representative, [        ], as Initial Senior Lien Collateral Agent,
[                    ], as
Initial Junior Lien Representative, [            ], as Initial Junior
Lien Collateral Agent and certain other persons party to the Junior Lien Subordination and Intercreditor Agreement or that may
become party thereto from time to time. In the event of any conflict between the terms of the Junior Lien Subordination and Intercreditor
Agreement and this Agreement, the terms of the Junior Lien Subordination and Intercreditor Agreement shall govern and control.”

 

5.7   
Gratuitous Bailee/Agent for Perfection; Rights of Initial Senior Collateral Agent and Initial Senior Lien Representative.

 

(a)    
Each Senior Lien Collateral Agent agrees to hold that part of the Collateral that is in its possession or control (or in
the possession or control of its agents or bailees) to the extent that possession or control thereof is taken to perfect a Lien
thereon under the UCC (such Collateral being the “Pledged Collateral”) as collateral agent for the Senior Lien
Claimholders and gratuitous bailee for the Junior Lien Collateral Agents (such bailment being intended, among other things, to
satisfy the requirements of Sections 8-106(d)(3), 8-301(a)(2) and 9-313(c) of the UCC) and any assignee thereof solely for
the purpose

 

    	 	22	 

     

    

of perfecting the security interest granted under
the Senior Lien Documents and the Junior Lien Documents, respectively, subject to the terms and conditions of this Section 5.7.
Solely with respect to any deposit accounts under the control (within the meaning of Section 9-104 of the UCC) of any Senior
Lien Collateral Agent, such Senior Lien Collateral Agent hereby agrees to also hold control over such deposit accounts as gratuitous
agent for the Junior Lien Collateral Agents, subject to the terms and conditions of this Section 5.7.

 

(b)    
No Senior Lien Collateral Agent shall have any obligation whatsoever to the Junior Lien Representatives, the Junior Lien
Collateral Agents or the Junior Lien Claimholders to ensure that the Pledged Collateral is genuine or owned by the Company, to
perfect the security interests of the Junior Lien Collateral Agents or other Junior Lien Claimholders or to preserve rights or
benefits of any Person except as expressly set forth in this Section 5.7. The duties or responsibilities of any Senior
Lien Collateral Agent under this Section 5.7 shall be limited solely to holding the Pledged Collateral as gratuitous
bailee (and with respect to deposit accounts, agent) in accordance with this Section 5.7 and delivering the Pledged
Collateral upon a Discharge of Senior Lien Obligations as provided in paragraph (d) below.

 

(c)    
No Senior Lien Collateral Agent or any other Senior Lien Claimholder shall have by reason of the Senior Lien Collateral
Documents, the Junior Lien Collateral Documents, this Agreement or any other document, a fiduciary relationship in respect of any
Junior Lien Representative or any other Junior Lien Claimholder and the Junior Lien Representatives, the Junior Lien Collateral
Agents and the Junior Lien Claimholders hereby waive and release the Senior Lien Collateral Agents and the other Senior Lien Claimholders
from all claims and liabilities arising pursuant to any Senior Lien Collateral Agent’s role under this Section 5.7
as gratuitous bailee and gratuitous agent with respect to the Pledged Collateral. It is understood and agreed that the interests
of the Senior Lien Collateral Agents and the other Senior Lien Claimholders, on the one hand, and the Junior Lien Representatives,
the Junior Lien Collateral Agents and the other Junior Lien Claimholders on the other hand, may differ and the Senior Lien Collateral
Agents and the other Senior Lien Claimholders shall be fully entitled to act in their own interest without taking into account
the interests of the Junior Lien Representatives, the Junior Lien Collateral Agents or other Junior Lien Claimholders.

 

(d)    
Upon the Discharge of Senior Lien Obligations, each Senior Lien Collateral Agent shall deliver the remaining Pledged Collateral
in its possession (if any) together with any necessary endorsements (which endorsement shall be without recourse and without any
representation or warranty), (x) unless a Discharge of Junior Lien Obligations has not already occurred, to the Junior Lien
Collateral Agent and (y) if a Discharge of Junior Lien Obligations has already occurred, to the Company or to whomever may
be lawfully entitled to receive the same. Following the Discharge of Senior Lien Obligations, each Senior Lien Collateral Agent
further agrees to take all other action required or requested by any Junior Lien Collateral Agent at the expense of the Company
in connection with the Junior Lien Collateral Agents obtaining a first-priority security interest in the Collateral. After the
Discharge of Senior Lien Obligations has occurred, upon the Discharge of Junior Lien Obligations, each Junior Lien Collateral Agent
shall deliver the remaining Pledged Collateral in its possession (if any) together with any necessary endorsements (which endorsement
shall be without recourse and without any representation or warranty, to the Company or to whomever may be lawfully entitled to
receive the same.

 

(e)    
Upon execution of this Agreement, each Junior Lien Representative and Junior Lien Collateral Agent shall, promptly following
such requirements or requests, (x) enter into such documents and agreements as the Company or the Initial Senior Lien Representative
and/or the Initial Senior Lien Collateral Agent or Initial Senior Lien Representative shall reasonably request in order to provide
to the Initial Senior Lien Collateral Agent and Initial Senior Lien Representative the rights contemplated hereby, in each case
consistent in all material respects with the terms of this Agreement and (y) deliver to such Initial Senior Lien Collateral
Agent any Pledged Collateral held by it together with any necessary endorsements (or otherwise allow such Initial Senior Lien Collateral
Agent to obtain control of such Pledged Collateral), provided that the Junior Lien Representative or Junior Lien Collateral
Agent shall not be required to take any action if such actions would violate applicable law or court order.

 

5.8   
When Discharge of Obligations Deemed to Not Have Occurred. If, at any time after the Discharge of Senior Lien Obligations
has occurred or contemporaneously therewith, the Company enters into any Refinancing of

 

    	 	23	 

     

    

any Senior Lien Documents evidencing a Senior Lien Obligation,
then such Discharge of Senior Lien Obligations shall automatically be deemed not to have occurred for all purposes of this Agreement
(other than with respect to any actions taken as a result of the occurrence of such first Discharge of Senior Lien Obligations),
and, from and after the date on which the Additional Senior Lien Representative and Additional Senior Lien Collateral Agent in
respect of such Refinancing each becomes a party to this Agreement in accordance with Section 8.7(b), the obligations under
such Refinancing of the applicable Senior Lien Documents shall automatically be treated as Senior Lien Obligations for all purposes
of this Agreement, including for purposes of the Lien priorities and rights in respect of Collateral set forth herein, and the
Additional Senior Lien Representative and the Additional Senior Lien Collateral Agent under such new Senior Lien Documents shall
be a Senior Lien Representative and Senior Lien Collateral Agent, respectively, for all purposes of this Agreement. Upon receipt
of a Designation from the Company in accordance with Section 8.7(b)(2) of this Agreement, each Junior Lien Representative
and Junior Lien Collateral Agent shall, promptly following such requests, (x) enter into such documents and agreements (including
amendments or supplements to this Agreement) as the Company or any one or more such Additional Senior Lien Representative and such
Additional Senior Lien Collateral Agent shall reasonably request in order to provide to such Additional Senior Lien Representative
and such Additional Senior Lien Collateral Agent the rights contemplated hereby, in each case consistent in all material respects
with the terms of this Agreement and (y) deliver to such Additional Senior Lien Collateral Agent any Pledged Collateral held
by it together with any necessary endorsements (or otherwise allow such Additional Senior Lien Collateral Agent to obtain control
of such Pledged Collateral), provided that the Junior Lien Representative and Junior Lien Collateral Agent shall not be required
to take any action if such actions would violate applicable law or court order. If the Additional Senior Lien Obligations under
the Additional Senior Lien Documents in respect of such Refinancing are secured by assets of the Company constituting Collateral
that do not also secure the Junior Lien Obligations, then the Junior Lien Obligations shall be secured at such time by a junior-priority
Lien on such assets to the same extent provided in the Junior Lien Collateral Documents and this Agreement except to the extent,
with respect to any Series of Junior Lien Obligations, such Lien on such assets constitutes a Junior Lien Declined Lien.

 

		Section 6.	Insolvency or Liquidation Proceedings.

 

6.1   
Finance and Sale Issues. Until the Discharge of Senior Lien Obligations has occurred, if the Company shall be subject
to any Insolvency or Liquidation Proceeding and any Senior Lien Representative shall desire to permit the use of “Cash Collateral”
(as such term is defined in Section 363(a) of the Bankruptcy Code) on which such Senior Lien Representative, such Senior Lien
Collateral Agent or any other creditor has a Lien, or to permit the Company to obtain financing, whether from the Senior Lien Claimholders
or any other Person under Section 364 of the Bankruptcy Code or any similar Bankruptcy Law (“DIP Financing”),
then each Junior Lien Representative and each Junior Lien Collateral Agent, for itself and on behalf of each other Junior Lien
Claimholder represented by it, will not object to such Cash Collateral use or DIP Financing (including any proposed orders for
either or both such Cash Collateral use and DIP Financing which are acceptable to any Senior Lien Representative) and to the extent
the Liens securing the Senior Lien Obligations are subordinated to or pari passu with such DIP Financing, each Junior Lien Collateral
Agent will subordinate its Liens in the Collateral to the Liens securing such DIP Financing (and all Obligations relating thereto)
and each Junior Lien Representative and each Junior Lien Collateral Agent, for itself and on behalf of each other Junior Lien Claimholder
represented by it, will not request adequate protection or any other relief in connection therewith (except as expressly agreed
by the Designated Senior Lien Representative or to the extent permitted by Section 6.3); provided that the Junior Lien Representatives
and the other Junior Lien Claimholders retain the right to object to any ancillary agreements or arrangements regarding Cash Collateral
use or the DIP Financing that are materially prejudicial to their interests. No Junior Lien Claimholder may provide DIP Financing
to the Company secured by Liens equal or senior in priority to the Liens securing any Senior Lien Obligations. Each Junior Lien
Representative and each Junior Lien Collateral Agent, for itself and on behalf of each other Junior Lien Claimholder represented
by it, agrees that it will not seek consultation rights in connection with, and it will not object to or oppose, a motion to sell,
liquidate or otherwise dispose of Collateral under Section 363 of the Bankruptcy Code if the requisite Senior Lien Claimholders
have consented to such sale, liquidation or other disposition. Each Junior Lien Representative and each Junior Lien Collateral
Agent, for itself and on behalf of each other Junior Lien Claimholder represented by it, further agrees that it will not directly
or indirectly oppose or impede entry of any order in connection with such sale, liquidation or other disposition, including orders
to retain professionals or set bid procedures in connection with such sale, liquidation or disposition, if the requisite Senior
Lien Claimholders have consented to (i) such retention of professionals and bid procedures in connection with such

 

    	 	24	 

     

    

sale, liquidation or disposition of such assets and (ii) the
sale, liquidation or disposition of such assets, in which event the Junior Lien Claimholders will be deemed to have consented to
the sale or disposition of Collateral pursuant to Section 363(f) of the Bankruptcy Code and such order does not materially
impair the rights of the Junior Lien Claimholders under Section 363(k) of the Bankruptcy Code.

 

Notwithstanding any other provision hereof
to the contrary, each Junior Lien Representative and each Junior Lien Collateral Agent, for itself and on behalf of each other
Junior Lien Claimholder represented by it, agrees that (A) without the consent of the Senior Lien Claimholders, none of such
Junior Lien Representative or such Junior Lien Collateral Agent, the Junior Lien Claimholders represented by it or any agent or
the trustee on behalf of any of them shall, for any purpose during any Insolvency or Liquidation Proceeding or otherwise, support,
endorse, propose or submit, whether directly or indirectly, any valuation of the Company or their respective assets that allocates
or ascribes any value whatsoever to any of the Restricted Assets and (B) without the consent of the Senior Lien Claimholders,
none of such Junior Lien Representative or such Junior Lien Collateral Agent, the Junior Lien Claimholders represented by it or
any agent or trustee on behalf of any of them shall for any purpose during any Insolvency or Liquidation Proceeding or otherwise,
challenge, dispute or object, whether directly or indirectly, to any valuation of the Company or its assets, or otherwise take
any position with respect to such valuation, that is proposed, supported or otherwise arises in any Insolvency or Liquidation Proceeding,
on grounds that such valuation does not allocate or ascribe adequate or appropriate value to any of the Restricted Assets.

 

6.2   
Relief from the Automatic Stay. Until the Discharge of Senior Lien Obligations has occurred, each Junior Lien Representative
and each Junior Lien Collateral Agent, for itself and on behalf of each other Junior Lien Claimholder represented by it, agrees
that none of them shall: (i) seek (or support any other Person seeking) relief from the automatic stay or any other stay in
any Insolvency or Liquidation Proceeding in respect of the Collateral or the Restricted Assets, without the prior written consent
of all of the Senior Lien Representatives, unless a motion for adequate protection permitted under Section 6.3 has
been denied by a bankruptcy court or (ii) oppose (or support any other Person in opposing) any request by any Senior Lien
Representative or Senior Lien Collateral Agent for relief from such stay.

 

6.3   
Adequate Protection.

 

(a)    
Each Junior Lien Representative and each Junior Lien Collateral Agent, for itself and on behalf of each other Junior Lien
Claimholder represented by it, agrees that none of them shall contest (or support any other Person contesting):

 

(1)    
any request by any Senior Lien Representative, any Senior Lien Collateral Agent or other Senior Lien Claimholder for adequate
protection under any Bankruptcy Law; or

 

(2)    
any objection by any Senior Lien Representative, any Senior Lien Collateral Agent or other Senior Lien Claimholder to any
motion, relief, action or proceeding based on such Senior Lien Representative, Senior Lien Collateral Agent or Senior Lien Claimholder
claiming a lack of adequate protection.

 

(b)    
Notwithstanding the foregoing provisions in this Section 6.3, in any Insolvency or Liquidation Proceeding:

 

(1)    
if the Senior Lien Claimholders (or any subset thereof) are granted adequate protection in the form of additional collateral
in connection with any  Cash Collateral use or DIP Financing, then each Junior Lien Collateral
Agent, for itself or on behalf of any other Junior Lien Claimholder represented by it, may seek or request adequate protection
in the form of a Lien on such additional collateral, which Lien will be subordinated to the Liens securing the Senior Lien Obligations
and such Cash Collateral use or DIP Financing (and all Obligations relating thereto) on the same basis as the other Liens securing
the Junior Lien Obligations are so subordinated to the Senior Lien Obligations under this Agreement; and

 

(2)    
the Junior Lien Representatives, the Junior Lien Collateral Agents and Junior Lien Claimholders shall only be permitted
to seek adequate protection with respect to their rights in the Collateral in any Insolvency or Liquidation Proceeding in the form
of (A) additional collateral;

 

    	 	25	 

     

    

provided that as adequate protection for the
Senior Lien Obligations, each Senior Lien Collateral Agent, on behalf of the Senior Lien Claimholders represented by it, is also
granted a Lien on such additional collateral, which Lien shall be senior to any Lien of the Junior Lien Representatives, the Junior
Lien Collateral Agents and the Junior Lien Claimholders on such additional collateral; (B) replacement Liens on the Collateral;
provided that as adequate protection for the Senior Lien Obligations, each Senior Lien Collateral Agent, on behalf of the
Senior Lien Claimholders represented by it, is also granted replacement Liens on the Collateral, which Liens shall be senior to
the Liens of the Junior Lien Representatives, the Junior Lien Collateral Agents and the Junior Lien Claimholders on the Collateral;
(C) an administrative expense claim; provided that as adequate protection for the Senior Lien Obligations, each Senior
Lien Representative, on behalf of the Senior Lien Claimholders represented by it, is also granted an administrative expense claim
which is senior and prior to the administrative expense claim of the Junior Lien Representatives and the other Junior Lien Claimholders;
and (D) cash payments with respect to interest on the Junior Lien Obligations; provided that (1) as adequate protection
for the Senior Lien Obligations, each Senior Lien Representative, on behalf of the Senior Lien Claimholders represented by it,
is also granted cash payments with respect to interest on the Senior Lien Obligation represented by it and (2) such cash payments
do not exceed an amount equal to the interest accruing on the principal amount of Junior Lien Obligations outstanding on the date
such relief is granted at the interest rate under the applicable Junior Lien Documents and accruing from the date the applicable
Junior Lien Representative is granted such relief. If any Junior Lien Claimholder receives Post-Petition Interest and/or adequate
protection payments in an Insolvency or Liquidation Proceeding (“Junior Lien Adequate Protection Payments”)
and the Senior Lien Claimholders do not receive payment in full in cash of all Senior Lien Obligations upon the effectiveness of
the plan of reorganization for, or conclusion of, that Insolvency or Liquidation Proceeding, then each Junior Lien Claimholder
shall pay over to the Senior Lien Claimholders an amount (the “Pay-Over Amount”) equal to the lesser of (i) the
Junior Lien Adequate Protection Payments received by such Junior Lien Claimholder and (ii) the amount of the short-fall (the
“Short Fall”) in payment in full in cash of the Senior Lien Obligations; provided that to the extent
any portion of the Short Fall represents payments received by the Senior Lien Claimholders in the form of promissory notes, equity
or other property equal in value to the cash paid in respect of the Pay-Over Amount, the Senior Lien Claimholders shall, upon receipt
of the Pay-Over Amount, transfer those promissory notes, equity or other property, equal in value to the cash paid in respect of
the Pay-Over Amount, to the applicable Junior Lien Claimholders pro rata in exchange for the Pay-Over Amount. Notwithstanding anything
herein to the contrary, the Senior Lien Claimholders shall not be deemed to have consented to, and expressly retain their rights
to object to, the grant of adequate protection in the form of cash payments to the Junior Lien Claimholders made pursuant to this
Section 6.3(b).

 

6.4   
No Waiver. Subject to Section 6.7(b), nothing contained herein shall prohibit or in any way limit any Senior
Lien Representative or any other Senior Lien Claimholder from objecting in any Insolvency or Liquidation Proceeding or otherwise
to any action taken by any Junior Lien Representative or any other Junior Lien Claimholder, including the seeking by any Junior
Lien Representative or any other Junior Lien Claimholder of adequate protection or the asserting by any Junior Lien Representative
or any other Junior Lien Claimholder of any of its rights and remedies under the Junior Lien Documents or otherwise.

 

6.5   
Avoidance Issues. If any Senior Lien Claimholder is required in any Insolvency or Liquidation Proceeding or otherwise
to turn over or otherwise pay to the estate of the Company any amount paid in respect of Senior Lien Obligations (a “Recovery”),
then such Senior Lien Claimholder shall be entitled to a reinstatement of its Senior Lien Obligations with respect to all such
recovered amounts on the date of such Recovery, and from and after the date of such reinstatement the Discharge of Senior Lien
Obligations shall be deemed not to have occurred for all purposes hereunder. If this Agreement shall have been terminated prior
to such Recovery, this Agreement shall be reinstated in full force and effect, and such prior termination shall not diminish, release,
discharge, impair or otherwise affect the obligations of the parties hereto from such date of reinstatement. This Section 6.5
shall survive termination of this Agreement.

 

    	 	26	 

     

    

6.6   
Reorganization Securities. If, in any Insolvency or Liquidation Proceeding, debt obligations of the reorganized debtor
secured by Liens upon any property of the reorganized debtor are distributed pursuant to a plan of reorganization, arrangement,
compromise or liquidation or similar dispositive restructuring plan, both on account of Senior Lien Obligations and on account
of Junior Lien Obligations, then, to the extent the debt obligations distributed on account of the Senior Lien Obligations and
on account of the Junior Lien Obligations are secured by Liens upon the same property, the provisions of this Agreement will survive
the distribution of such debt obligations pursuant to such plan and will apply with like effect to the Liens securing such debt
obligations.

 

6.7   
Post-Petition Interest.

 

(a)    
None of any Junior Lien Representative, any Junior Lien Collateral Agent or any other Junior Lien Claimholder shall oppose
or seek to challenge any claim by any Senior Lien Representative, any Senior Lien Collateral Agent or any other Senior Lien Claimholder
for allowance in any Insolvency or Liquidation Proceeding of Senior Lien Obligations consisting of Post-Petition Interest to the
extent of the value of the Lien of the Senior Lien Collateral Agents on behalf of the Senior Lien Claimholders on the Collateral
or any other Senior Lien Claimholder’s Lien on the Collateral, without regard to the existence of the Liens of the Junior
Lien Collateral Agents or the other Junior Lien Claimholders on the Collateral.

 

(b)    
None of any Senior Lien Representative, Senior Lien Collateral Agent or any other Senior Lien Claimholder shall oppose or
seek to challenge any claim by any Junior Lien Representative, Junior Lien Collateral Agent or any other Junior Lien Claimholder
for allowance in any Insolvency or Liquidation Proceeding of Junior Lien Obligations consisting of Post-Petition Interest to the
extent of the value of the Lien of the Junior Lien Collateral Agents, on behalf of the Junior Lien Claimholders, on the Collateral
(after taking into account the amount of the Senior Lien Obligations).

 

6.8   
Waiver. Each Junior Lien Representative and each Junior Lien Collateral Agent, for itself and on behalf of each other
Junior Lien Claimholder represented by it, waives any claim it may hereafter have against any Senior Lien Claimholder arising out
of the election of any Senior Lien Claimholder of the application of Section 1111(b)(2) of the Bankruptcy Code, and out of
any cash collateral or financing arrangement or out of any grant of a security interest in connection with the Collateral in any
Insolvency or Liquidation Proceeding so long as such actions are not in express contravention of the terms of this Agreement.

 

6.9   
Separate Grants of Security and Separate Classification. Each Junior Lien Representative and each Junior Lien Collateral
Agent, for itself and on behalf of each other Junior Lien Claimholder represented by it, and each Senior Lien Representative and
each Senior Lien Collateral Agent, for itself and on behalf of each other Senior Lien Claimholder represented by it, acknowledges
and agrees that:

 

(a)    
the grants of Liens pursuant to the Senior Lien Collateral Documents and the Junior Lien Collateral Documents constitute
two separate and distinct grants of Liens; and

 

(b)    
because of, among other things, their differing rights in the Collateral, the Junior Lien Obligations are fundamentally
different from the Senior Lien Obligations and must be separately classified in any plan of reorganization proposed or adopted
in an Insolvency or Liquidation Proceeding.

 

To further effectuate the intent of the
parties as provided in the immediately preceding sentence, if it is held that the claims of the Senior Lien Claimholders and the
Junior Lien Claimholders in respect of the Collateral constitute only one secured claim (rather than separate classes of senior
and junior secured claims), then each of the parties hereto hereby acknowledges and agrees that all distributions shall be made
as if there were separate classes of senior and junior secured claims against the Company in respect of the Collateral (with the
effect being that, to the extent that the aggregate value of the Collateral is sufficient (for this purpose ignoring all claims
held by the Junior Lien Claimholders), the Senior Lien Claimholders shall be entitled to receive, in addition to amounts distributed
to them in respect of principal, pre-petition interest and other claims, all amounts owing (or that would be owing if there were
such separate classes of senior and junior secured claims) in respect of Post-Petition Interest (including any additional interest
payable pursuant to the Senior Lien Documents, arising from or related to a default, which is disallowed as a claim in any Insolvency
or Liquidation Proceeding) before any distribution is made in respect of the claims held by the Junior Lien Claimholders with respect
to the Collateral, with each Junior Lien Representative and each Junior Lien Collateral Agent, for itself and on behalf of each
other Junior Lien Claimholder

 

    	 	27	 

     

    

represented by it, hereby acknowledging and agreeing to turn
over to the Designated Senior Lien Collateral Agent, for itself and on behalf of each other Senior Lien Claimholder, Collateral
or proceeds of Collateral otherwise received or receivable by them to the extent necessary to effectuate the intent of this sentence,
even if such turnover has the effect of reducing the claim or recovery of the Junior Lien Claimholders).

 

6.10 Effectiveness in Insolvency or Liquidation
Proceedings. The Parties acknowledge that this Agreement is a “subordination agreement” under section 510(a)
of the Bankruptcy Code, which will be effective before, during and after the commencement of an Insolvency or Liquidation Proceeding.
All references in this Agreement to the Company will include such Person as a debtor-in-possession and any receiver or trustee
for such Person in an Insolvency or Liquidation Proceeding.

 

		Section 7.	Reliance; Waivers.

 

7.1   
Reliance. Other than any reliance on the terms of this Agreement, each Senior Lien Representative and each Senior
Lien Collateral Agent, on behalf of itself and each other Senior Lien Claimholder represented by it, acknowledges that it and such

continuance of an event of default or default under any agreements with the Company (including the Senior Lien Documents and the
Junior Lien Documents), regardless of any knowledge thereof which they may have or be charged with.

 

7.3

(a)    
No right of the Senior Lien Claimholders, the Senior Lien Representatives, the Senior Lien Collateral Agents or any of them

Lien Claimholder, Senior Lien Representative or Senior Lien Collateral Agent, or by any noncompliance by any Person with the terms,
provisions and covenants of this Agreement, any of the Senior Lien Documents or any of the Junior Lien Documents, regardless of
any knowledge thereof which any Senior Lien Representative, Senior Lien Collateral Agent or any Senior Lien Claimholder, or any
of them, may have or be otherwise charged with.

		Section 8.	Miscellaneous.

 

8.1   
Integration/Conflicts. This Agreement, the Senior Lien Documents and the Junior Lien Documents represent the entire

hereof and thereof, and supersede any and all previous agreements and understandings, oral or written, relating to the subject
matter hereof and thereof. There are no promises, undertakings, representations or warranties by the Senior Lien Claimholders or

or the Junior Lien Documents, the provisions of this Agreement shall govern and control.

 

8.2   
Effectiveness; Continuing Nature of this Agreement; Severability. This Agreement shall become effective when executed
and delivered by the parties hereto. This is a continuing agreement of lien subordination

 

    	 	30	 

     

    

and the Senior Lien Claimholders may continue, at any time and
without notice to any Junior Lien Representative or any other Junior Lien Claimholder, to extend credit and other financial accommodations
and lend monies to or for the benefit of the Company or Centrus constituting Senior Lien Obligations in reliance hereon. Each Junior
Lien Representative and each Junior Lien Collateral Agent, on behalf of itself and each other Junior Lien Claimholder represented

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.
The parties hereto shall endeavor in good-faith negotiations to replace any invalid, illegal or unenforceable provisions with valid
provisions the economic effect of which comes as close as possible to those of the invalid, illegal or unenforceable provisions.
All references to the Company shall include the Company as debtor and debtor-in-possession and any receiver, trustee or similar
person acting for the Company (as the case may be) in any Insolvency or Liquidation Proceeding. This Agreement shall terminate

Passu-Lien Obligations of any Series are modified pursuant to applicable law (including, without limitation, pursuant to Section

Priorities and Agreements with Respect to Shared Collateral

 

SECTION
2.01        Priority of
Claims.

 

(a)               
Anything contained herein or in any of the Secured Note Documents to the contrary notwithstanding (but subject to
Section 1.03), if an Event of Default has occurred and is continuing, and the Controlling Collateral Agent or any Pari Passu-Lien
Secured Party is taking action to enforce rights in respect of any Shared Collateral, or any distribution is made in respect of
any Shared Collateral in any Bankruptcy Case of the Grantor or any Pari Passu-Lien Secured Party receives any payment pursuant
to any intercreditor agreement (other than this Agreement) with respect to any Shared Collateral, the proceeds of any sale, collection
or other liquidation of any such Shared Collateral by any Pari Passu-Lien Secured Party or received by the Controlling Collateral
Agent or any Pari Passu-Lien Secured Party pursuant to any such intercreditor agreement with respect to such Shared Collateral
and proceeds of any such distribution (subject, in the case of any such distribution, to the sentence immediately following) to
which the Pari Passu-Lien Obligations are entitled under any intercreditor agreement (other than this Agreement) (all proceeds
of any sale, collection or other liquidation of any Shared Collateral and all proceeds of any such distribution being collectively
referred to as “Proceeds”), shall be applied (i) FIRST, to the payment of all amounts owing to each Collateral
Agent (in its capacity as such) pursuant to the terms of any Secured Note Document, (ii) SECOND, subject to Section 1.03, to the
payment in full of the Pari Passu-Lien Obligations of each Series on a ratable basis, with such Proceeds to be applied to the Pari
Passu-Lien Obligations of a given Series in accordance with the terms of the applicable Secured Note Documents and (iii) THIRD,
after payment of all Pari Passu-Lien Obligations, to the Grantor or its successors or assigns, as their interests may appear, or
to whomsoever may be lawfully entitled to receive the same, or as a court of competent jurisdiction may direct. Notwithstanding
the foregoing, with respect to any Shared Collateral for which a third party (other than a Pari Passu-Lien Secured Party) has a
lien or security interest that is junior in priority to the security interest of any Series of Pari Passu-Lien Obligations but
senior (as determined by appropriate legal proceedings in the case of any dispute) to the security interest of any other Series
of Pari Passu-Lien Obligations (such third party, an “Intervening Creditor”), the value of any Shared Collateral
or Proceeds allocated to such Intervening Creditor shall be deducted on a ratable basis solely from the Shared Collateral or Proceeds
to be distributed in respect of the Series of Pari Passu-Lien Obligations with respect to which such Impairment exists.

 

    	 	-6-	 

     

    

 

(b)              
It is acknowledged that the Pari Passu-Lien Obligations of any Series may, subject to the limitations set forth in
the then extant Secured Note Documents, be increased, extended, renewed, replaced, restated, supplemented, restructured, repaid,
refunded, Refinanced or otherwise amended or modified from time to time, all without affecting the priorities set forth in Section
2.01(a) or the provisions of this Agreement defining the relative rights of the Pari Passu-Lien Secured Parties of any Series.

 

(c)               
Notwithstanding the date, time, method, manner or order of grant, attachment or perfection of any Liens securing
any Series of Pari Passu-Lien Obligations granted on the Shared Collateral and notwithstanding any provision of the Uniform Commercial
Code of any jurisdiction, or any other applicable law or the Secured Note Documents or any defect or deficiencies in the Liens
securing the Pari Passu-Lien Obligations of any Series or any other circumstance whatsoever (but, in each case, subject to Section
1.03), each Pari Passu-Lien Secured Party hereby agrees that the Liens securing each Series of Pari Passu-Lien Obligations
on any Shared Collateral shall be of equal priority.

 

SECTION
2.02            
Actions with Respect to Shared Collateral; Prohibition on Contesting Liens.

 

(a)               
Only the Controlling Collateral Agent shall act or refrain from acting with respect to any Shared Collateral (including
with respect to any intercreditor agreement with respect to any Shared Collateral). No Non-Controlling Secured Party shall or shall
instruct any Collateral Agent to, and no Non-Controlling Collateral Agent shall, 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, exercise any right, remedy or power with respect to, or otherwise take any action to enforce its
security interest in or realize upon, or take any other action available to it in respect of, any Shared Collateral (including
with respect to any intercreditor agreement with respect to any Shared Collateral), whether under any Pari Passu-Lien Security
Document, applicable law or otherwise, it being agreed that only the Controlling Collateral Agent, acting in accordance with the
Pari Passu-Lien Security Documents, shall be entitled to take any such actions or exercise any such remedies with respect to Shared
Collateral at such time.

 

    	 	-7-	 

     

    

 

(b)              
With respect to any Shared Collateral, (i) the Controlling Collateral Agent shall act only on the instructions of
the Applicable Authorized Representative, (ii) the Controlling Collateral Agent shall not follow any instructions with respect
to such Shared Collateral (including with respect to any intercreditor agreement with respect to any Shared Collateral) from any
Non-Controlling Authorized Representative (or any other Pari Passu-Lien Secured Party other than the Applicable Authorized Representative)
and (iii) no Non-Controlling Authorized Representative or other Pari Passu-Lien Secured Party (other than the Applicable Authorized
Representative) shall or shall instruct the Controlling Collateral Agent to, commence any judicial or non-judicial 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, exercise any right, remedy or power with respect to, or otherwise take any action to enforce its
security interest in or realize upon, or take any other action available to it in respect of, any Shared Collateral (including
with respect to any intercreditor agreement with respect to any Shared Collateral), whether under any Pari Passu-Lien Security
Document, applicable law or otherwise, it being agreed that only the Controlling Collateral Agent, acting on the instructions of
the Applicable Authorized Representative and in accordance with the Pari Passu-Lien Security Documents applicable to it, shall
be entitled to take any such actions or exercise any such remedies with respect to such Shared Collateral.

 

(c)               
Notwithstanding the equal priority of the Liens securing each Series of Pari Passu-Lien Obligations with respect
to any Shared Collateral, the Controlling Collateral Agent with respect thereto (acting on the instructions of the Applicable Authorized
Representative) may deal with such Shared Collateral as if such Controlling Collateral Agent had a senior Lien on such Collateral.
No Non-Controlling Authorized Representative or Non-Controlling Secured Party in respect of any Shared Collateral will contest,
protest or object to any foreclosure proceeding or action brought by the Controlling Collateral Agent, the Applicable Authorized
Representative or any Controlling Secured Party or any other exercise by the Controlling Collateral Agent, the Applicable Authorized
Representative or a Controlling Secured Party of any rights and remedies relating to such Shared Collateral, or cause the Controlling
Collateral Agent to do so. The foregoing shall not be construed to limit the rights and priorities of any Pari Passu-Lien Secured
Party, the Controlling Collateral Agent or any Authorized Representative with respect to any Collateral not constituting Shared
Collateral.

 

(d)              
Each of the Pari Passu-Lien Secured Parties agrees that it will not (and hereby waives any right to) question or
contest or support any other Person in contesting, in any proceeding (including any Insolvency or Liquidation Proceeding), the
perfection, priority, validity, attachment or enforceability of a Lien held by or on behalf of any of the Pari Passu-Lien Secured
Parties in all or any part of the Shared Collateral, or the provisions of this Agreement; provided that nothing in this
Agreement shall be construed to prevent or impair the rights of any Collateral Agent or any Authorized Representative to enforce
this Agreement.

 

SECTION 2.03            
No Interference; Payment Over.

  

(a)               
Each Pari Passu-Lien Secured Party agrees that (i) it will not challenge or question or support any other Person
or entity in any proceeding the validity or enforceability of any Pari Passu-Lien Obligations of any Series or any Pari Passu-Lien
Security Document or the validity, attachment, perfection or priority of any Lien under any Pari Passu-Lien Security Document or
the validity or enforceability of the priorities, rights or duties established by or other provisions of this Agreement; (ii) it
will not take or cause to be taken any action the purpose or intent of which is, or could be, to interfere, hinder or delay, in
any manner, whether by judicial proceedings or otherwise, any sale, transfer or other disposition of any Shared Collateral by the
Controlling Collateral Agent, (iii) except as provided in Section 2.02, it shall have no right to (A) direct the Controlling
Collateral Agent or any other Pari Passu-Lien Secured Party to exercise, and shall not exercise, any right, remedy or power with
respect to any Shared Collateral (including pursuant to any intercreditor agreement) or (B) consent to the exercise by the Controlling
Collateral Agent or any other Pari Passu-Lien Secured Party of any right, remedy or power with respect to any Shared Collateral,
(iv) it will not institute any suit or assert in any suit, bankruptcy, insolvency or other proceeding any claim against the Controlling
Collateral Agent or any other Pari Passu-Lien 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 Controlling Collateral Agent, any Applicable Authorized
Representative or any other Pari Passu-Lien Secured Party shall be liable for any action taken or omitted to be taken by the Controlling
Collateral Agent, such Applicable Authorized Representative or other Pari Passu-Lien Secured Party with respect to any Shared Collateral
in accordance with the provisions of this Agreement, (v) it will not seek, and hereby waives any right, to have any Shared Collateral
or any part thereof marshaled upon any foreclosure or other disposition of such Shared Collateral, and (vi) it will not attempt,
directly or indirectly, whether by judicial proceedings or otherwise, to challenge the enforceability of any provision of this
Agreement; provided that nothing in this Agreement shall be construed to prevent or impair the rights of any of the Collateral
Agent or any other Pari Passu-Lien Secured Party to enforce this Agreement.

 

    	 	-8-	 

     

    

 

(b)              
Each Pari Passu-Lien Secured Party hereby agrees that if it shall obtain possession of any Shared Collateral or shall
realize any proceeds or payment in respect of any such Shared Collateral, pursuant to any Pari Passu-Lien Security Document by
the exercise of any rights available to it under applicable law or in any Insolvency or Liquidation Proceeding or through any other
exercise of remedies (including pursuant to any intercreditor agreement), at any time prior to the Discharge of each of the Pari
Passu-Lien Obligations, then it shall hold such Shared Collateral, proceeds or payment in trust for the other Pari Passu-Lien Secured
Parties and promptly transfer such Shared Collateral, proceeds or payment, as the case may be, to the Controlling Collateral Agent,
to be distributed in accordance with the provisions of Section 2.01 hereof.

 

SECTION 2.04            
Automatic Release of Liens.

 

(a)               
If, at any time the Controlling Collateral Agent forecloses upon or otherwise exercises remedies against any Shared
Collateral resulting in a sale or disposition thereof, then (whether or not any Insolvency or Liquidation Proceeding is pending
at the time) the Liens in favor of each other Collateral Agent for the benefit of each Series of Pari Passu-Lien Secured Parties
upon such Shared Collateral will automatically be released and discharged as and when, but only to the extent, such Liens of the
Controlling Collateral Agent on such Shared Collateral are released and discharged; provided that any proceeds of any Shared
Collateral realized therefrom shall be allocated and applied pursuant to Section 2.01.

 

(b)              
Each Collateral Agent and Authorized Representative agrees to execute and deliver (at the sole cost and expense of
the Grantor) all such authorizations and other instruments as shall reasonably be requested by the Controlling Collateral Agent
to evidence and confirm any release of Shared Collateral provided for in this Section.

 

SECTION 2.05            
Certain Agreements with Respect to Bankruptcy or Insolvency Proceedings.

 

(a)               
This Agreement shall continue in full force and effect notwithstanding the commencement of any proceeding under the
Bankruptcy Code or any other Federal, state or foreign bankruptcy, insolvency, receivership or similar law by or against either
Borrower or any of their respective Subsidiaries.

 

    	 	-9-	 

     

    

 

(b)              
If the 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 (the “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, each Pari Passu-Lien Secured Party (other than any Controlling Secured Party or the Authorized Representative
of any Controlling Secured Party) agrees that it will raise no objection to any such financing or to the Liens on the Shared Collateral
securing the same (“DIP Financing Liens”) or to any use of cash collateral that constitutes Shared Collateral,
unless the Controlling Collateral Agent (acting on the instructions of the Applicable Authorized Representative) shall then oppose
or object to such DIP Financing or such DIP Financing Liens or 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 Pari Passu-Lien 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 Pari Passu-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 Pari Passu-Lien Secured
Parties of each Series retain the benefit of their Liens on all such Shared Collateral pledged to the DIP Lenders, including proceeds
thereof arising after the commencement of such proceeding, with the same priority vis-à-vis all the other Pari Passu-Lien
Secured Parties (other than any Liens of the Pari Passu-Lien Secured Parties constituting DIP Financing Liens) as existed prior
to the commencement of the Bankruptcy Case, (B) the Pari Passu-Lien Secured Parties of each Series are granted Liens on any additional
collateral pledged to any Pari Passu-Lien Secured Parties as adequate protection or otherwise in connection with such DIP Financing
or use of cash collateral (in each case, except to the extent a Lien on additional collateral is granted to one Series in consideration
of Collateral of such Series that is not Shared Collateral for a Series that does not receive a Lien on such additional collateral),
with the same priority vis-à-vis the Pari Passu-Lien Secured Parties as set forth in this Agreement, (C) if any amount of
such DIP Financing or cash collateral is applied to repay any of the Pari Passu-Lien Obligations, such amount is applied pursuant
to Section 2.01 (in each case, except to the extent a payment is made to one Series in consideration of Collateral of such
Series that is not Shared Collateral for a Series that does not receive such payment), and (D) if any Pari Passu-Lien Secured Parties
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 pursuant to Section 2.01 (in each case, except to the extent
such adequate protection is granted to one Series in consideration of Collateral of such Series that is not Shared Collateral for
a Series that does not receive such adequate protection); provided that the Pari Passu-Lien Secured Parties of each Series
shall have a right to object to the grant of a Lien to secure the DIP Financing over any Collateral subject to Liens in favor of
the Pari Passu-Lien Secured Parties of such Series or its Authorized Representative that shall not constitute Shared Collateral;
and provided further that the Pari Passu-Lien Secured Parties receiving adequate protection shall not object to any other
Pari Passu-Lien Secured Party receiving adequate protection comparable to any adequate protection granted to such Pari Passu-Lien
Secured Parties in connection with a DIP Financing or use of cash collateral.

 

SECTION 2.06            
Reinstatement. In the event that any of the Pari Passu-Lien Obligations shall be paid in full and such payment or
any part thereof shall subsequently, for whatever reason (including an order or judgment for disgorgement of a preference under
the Bankruptcy Code, or any similar law, or the settlement of any claim in respect thereof), be required to be returned or repaid,
the terms and conditions of this Article II shall be fully applicable thereto until all such Pari Passu-Lien Obligations shall
again have been paid in full in cash.

 

    	 	-10-	 

     

    

 

SECTION 2.07            
Insurance. As between the Pari Passu-Lien Secured Parties, the Controlling Collateral Agent shall have the right
to adjust or settle any insurance policy or claim covering or constituting Shared Collateral in the event of any loss thereunder
and to approve any award granted in any condemnation or similar proceeding affecting the Shared Collateral.

 

SECTION 2.08            
Refinancings. The Pari Passu-Lien Obligations of any Series may be Refinanced, in whole or in part, in each case,
without notice to, or the consent (except to the extent a consent is otherwise required to permit the Refinancing transaction under
any Secured Note Document) of any Pari Passu-Lien Secured Party of any other Series, all without affecting the priorities provided
for herein or the other provisions hereof; provided that the Authorized Representative of the holders of any such Refinancing indebtedness
shall have executed a Joinder Agreement on behalf of the holders of such Refinancing indebtedness.

 

SECTION 2.09            
Possessory Collateral Agent and Securities or Deposit Account Control Collateral Agent as Gratuitous Bailee for Perfection.

 

(a)               
Each Collateral Agent agrees to hold all Possessory Collateral or Securities or Deposit Account Control Collateral
that is 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 Pari Passu-Lien Secured Party for which such Possessory Collateral or Securities or Deposit Account Control Collateral
is Shared Collateral and any assignee solely for the purpose of perfecting the security interest granted in such Possessory Collateral
or Securities or Deposit Account Control Collateral, if any, pursuant to the applicable Pari Passu-Lien Security Documents, in
each case, subject to the terms and conditions of this Section 2.09; provided that at any time a Collateral Agent
ceases to be a Collateral Agent, such former Collateral Agent shall, at the request of the Controlling Collateral Agent, promptly
deliver all Possessory Collateral to the Controlling Collateral Agent together with any necessary endorsements (or otherwise allow
the Controlling Collateral Agent to obtain control of such Possessory Collateral). The Grantor shall take such further action as
is required to effectuate the transfer contemplated hereby and shall indemnify each Collateral Agent for loss or damage suffered
by such Collateral Agent as a result of such transfer except for loss or damage suffered by such Collateral Agent as a result of
its own willful misconduct, gross negligence or bad faith.

 

(b)              
Each Collateral Agent agrees to hold any Shared Collateral constituting Possessory Collateral or any Securities or
Deposit Account Control Collateral, from time to time in its possession, as gratuitous bailee for the benefit of each other Pari
Passu-Lien Secured Party and any assignee, solely for the purpose of perfecting the security interest granted in such Possessory
Collateral or such Securities or Deposit Account Control Collateral as applicable, if any, pursuant to the applicable Pari Passu-Lien
Security Documents, in each case, subject to the terms and conditions of this Section 2.09.

 

(c)               
The duties or responsibilities of each Collateral Agent under this Section 2.09 shall be limited solely to
holding any Shared Collateral constituting Possessory Collateral or Securities or Deposit Account Control Collateral as gratuitous
bailee for the benefit of each other Pari Passu-Lien Secured Party for purposes of perfecting the Lien held by such Pari Passu-Lien
Secured Parties thereon.

 

SECTION 2.10            
Amendments to Security Documents.

  

(a)               
Without the prior written consent of the New Notes Collateral Agent, each Existing Notes Secured Party agrees that
no Existing Notes Security Document may be amended, supplemented or otherwise modified or entered into to the extent such amendment,
supplement or modification, or the terms of any new Existing Notes Security Document would be prohibited by, or would require the
Grantor to act or refrain from acting in a manner that would violate, any of the terms of this Agreement.

 

    	 	-11-	 

     

    

 

(b)              
Without the prior written consent of the Existing Notes Collateral Agent, the New Notes Collateral Agent agrees that
no New Notes Security Document may be amended, supplemented or otherwise modified or entered into to the extent such amendment,
supplement or modification, or the terms of any new New Notes Security Document would be prohibited by, or would require the Grantor
to act or refrain from acting in a manner that would violate, any of the terms of this Agreement.

 

(c)               
In making determinations required by this Section 2.10, each Collateral Agent may conclusively rely on a certificate
of an authorized officer of the Grantor.

Existence and Amounts of Liens and Obligations 

 

SECTION 3.01            
Determinations with Respect to Amounts of Liens and Obligations.

 

Whenever a Collateral Agent or any Authorized
Representative shall be required, in connection with the exercise of its rights or the performance of its obligations hereunder,
to determine the existence or amount of any Pari Passu-Lien Obligations of any Series, or the Shared Collateral subject to any
Lien securing the Pari Passu-Lien Obligations of any Series, it may request that such information be furnished to it in writing
by each other Authorized Representative or Collateral Agent and shall be entitled to make such determination or not make any determination
on the basis of the information so furnished; provided, however, that if an Authorized Representative or a Collateral
Agent 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 a certificate of Issuer. Each 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 Issuer, the
Grantor, any Pari Passu-Lien Secured Party or any other person as a result of such determination.

The Controlling Collateral Agent 

 

SECTION 4.01            
Authority. 

 

(a)               
Notwithstanding any other provision of this Agreement, nothing herein shall be construed to impose any fiduciary
or other duty on any Controlling Collateral Agent to any Non-Controlling Secured Party or give any Non-Controlling Secured Party
the right to direct any Controlling Collateral Agent, except that each Controlling Collateral Agent shall be obligated to distribute
proceeds of any Shared Collateral in accordance with Section 2.01 hereof.

 

(b)              
In furtherance of the foregoing, each Non-Controlling Secured Party acknowledges and agrees that the Controlling
Collateral Agent shall be entitled, for the benefit of the Pari Passu-Lien Secured Parties, to sell, transfer or otherwise dispose
of or deal with any Shared Collateral as provided herein and in the Pari Passu-Lien Security Documents, as applicable, pursuant
to which the Controlling Collateral Agent is the collateral agent for such Shared Collateral, without regard to any rights to which
the Non-Controlling Secured Parties would otherwise be entitled as a result of the Pari Passu-Lien Obligations held by such Non-Controlling
Secured Parties. Without limiting the foregoing, each Non-Controlling Secured Party agrees that none of the Controlling Collateral
Agent, the Applicable Authorized Representative or any other Pari Passu-Lien 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 Pari Passu-Lien Obligations),
or to sell, dispose of or otherwise liquidate all or any portion of such Shared Collateral (or any other Collateral securing any
Pari Passu-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 Pari Passu-Lien
Secured Parties waives any claim it may now or hereafter have against any Collateral Agent or the Authorized Representative of
any other Series of Pari Passu-Lien Obligations or any other Pari Passu-Lien Secured Party of any other Series arising out of (i)
any actions which any Collateral Agent, Authorized Representative or the Pari Passu-Lien Secured Parties take or omit 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, 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 Pari Passu-Lien Obligations from any account debtor, guarantor or any other party) in accordance
with the Pari Passu-Lien Security Documents or any other agreement related thereto or to the collection of the Pari Passu-Lien
Obligations or the valuation, use, protection or release of any security for the Pari Passu-Lien Obligations, (ii) any election
by any Applicable Authorized Representative or any holders of Pari Passu-Lien Obligations, in any proceeding instituted under the
Bankruptcy Code, of the application of Section 1111(b) of the Bankruptcy Code or (iii) subject to Section 2.05, 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 Issuer, the Grantor or any of their respective Subsidiaries, as debtor-in-possession.
Notwithstanding any other provision of this Agreement, the Controlling Collateral Agent shall not accept any Shared Collateral
in full or partial satisfaction of any Pari Passu-Lien Obligations pursuant to Section 9-620 of the Uniform Commercial Code of
any jurisdiction, without the consent of each Authorized Representative representing holders of Pari Passu-Lien Obligations for
whom such Collateral constitutes Shared Collateral.

Waivers; Amendment; Joinder Agreements.

  

(a)               
No failure or delay on the part of any party hereto in exercising any right or power hereunder shall operate as a
waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps
to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The
rights and remedies of the parties hereto are cumulative and are not exclusive of any rights or remedies that they would otherwise
have. No waiver of any provision of this Agreement or consent to any departure by any party therefrom shall in any event be effective

the case of a nonpayment default on the Senior Lien Obligations, upon the earlier of the date on which such nonpayment default
is cured or waived or 179 days after the date on which the applicable Payment Blockage Notice is received, unless, in the case
of this clause (2), the maturity of any Senior Lien Obligations has been accelerated or demand for payment of such Senior Lien
Obligations made, and such acceleration or demand for payment has not been waived, satisfied or cancelled;

 

if the Initial Junior Lien Agreement or other applicable Junior
Lien Documents otherwise permits such payment, distribution or acquisition at the time of such payment, distribution or acquisition.

 

2.3       Junior
Lien Obligations Standstill Provisions.

 

The Junior Lien Representative shall not,
without the prior written consent of the Senior Lien Representative, take any Enforcement Action with respect to the Junior Lien
Obligations (for the avoidance of doubt, Collateral Enforcement Actions shall be governed by Section 3.1, below and
not this Section 2.3), until the earliest to occur of the following:

 

(a)       acceleration
of the Senior Lien Obligations (provided, however, that if, following any such acceleration of the Senior Lien Obligations, such
acceleration in respect of the Senior Lien Obligations is rescinded, then all Enforcement Actions taken by any Junior Lien Claimholders
shall likewise be rescinded if the Junior Lien Claimholders would not otherwise have any right under the last paragraph of this
Section 2.3 to take any Enforcement Action);

 

(b)       an
Insolvency or Liquidation Proceeding with respect to the Company shall have been commenced (provided, however, that if such Insolvency
or Liquidation Proceeding is dismissed, the corresponding prohibition against the Junior Lien Claimholders taking any Enforcement
Action shall automatically be reinstated as of the date of dismissal as if such Insolvency or Liquidation Proceeding had not been
initiated, unless the Junior Lien Claimholder shall have the right to take any Enforcement Action under the last paragraph of this
Section 2.3); or

 

    11 

     

    

 

(c)       the
stated final maturity of the Junior Lien Obligations.

 

Any Distributions on account of a Junior
Lien Obligation or other proceeds of any Enforcement Action obtained by any Junior Lien Claimholders shall in any event be held
in trust by it for the benefit of the Senior Lien Obligations and promptly be paid or delivered to the Senior Lien Collateral Agent
in the form received until all Senior Lien Obligations are paid in full.

 

Anything contained in this Agreement to
the contrary notwithstanding, no provision herein shall prevent any Junior Lien Claimholders from (i) filing lawsuits to prevent
the expiration of any applicable statute of limitations or other similar restrictions on claims, or (ii) seeking specific
performance or other injunctive relief to compel the Company to comply with a non-payment obligation under the Junior Lien Documents.

 

2.4       Liquidation,
Dissolution, Bankruptcy.

 

In the event of any Insolvency or Liquidation
Proceeding that is continuing involving the Company:

 

This Agreement shall remain in full force
and effect and enforceable pursuant to its terms, and all references herein to the Company shall be deemed to apply to the Company
as debtor-in-possession and to any Person claiming through or on their behalf, including a trustee in bankruptcy, receiver, assignee
for the benefit of creditors, liquidating trustee or agent for the estate of the Company, or otherwise.

 

All Senior Lien Obligations shall first
be paid in full before any Distribution, whether in cash, securities or other property, shall be made to any Junior Lien Claimholder
(or any Person claiming through or on behalf of any Junior Lien Claimholder, including a trustee in bankruptcy, receiver, assignee
for the benefit of creditors, liquidating trustee or agent, or otherwise) on account of any Junior Lien Obligations.

 

Any Distribution, whether in cash, securities
or other property, which would otherwise, but for the terms hereof, be payable or deliverable in respect of the Junior Lien Obligations
shall be paid or delivered directly to the Senior Lien Collateral Agent until all Senior Lien Obligations are paid in full. Each
Junior Lien Claimholder by its acceptance of the Junior Lien Documents irrevocably authorizes, empowers and directs any debtor,
debtor in possession, receiver, trustee, liquidator, custodian, conservator or other Person having authority, to pay or otherwise
deliver all such Distributions in respect of the Junior Lien Obligations to the Senior Collateral Agent. Each Junior Lien Claimholder
by its acceptance of the Junior Lien Documents also irrevocably authorizes and empowers the Senior Lien Collateral Agent, in the
name of such Junior Lien Claimholder, to demand, sue for, collect and receive any and all such Distributions. Neither any Senior
Lien Collateral Agent nor any Senior Lien Claimholder shall have any liability to any Junior Lien Claimholder in connection with
any action taken pursuant to this paragraph.

 

Each Junior Lien Claimholder by its acceptance
of the Junior Lien Documents agrees not to initiate, prosecute, support or participate in any claim, action or other proceeding
challenging the enforceability, validity, perfection or priority of the Senior Lien Obligations or any liens and security interests
securing the Senior Lien Obligations.

 

Each Junior Lien Claimholder may execute,
verify, deliver and file any proofs of claim in respect of the Junior Lien Obligations.

 

Section 3.Lien
Priorities.

 

Relative Priorities. Notwithstanding
the date, time, method, manner or order of grant, attachment or perfection of any Liens securing the Junior Lien Obligations granted
on the Collateral or of any Liens securing the Senior Lien Obligations granted on the Collateral and notwithstanding any provision
of the UCC or any other applicable law or the Junior Lien Documents or any defect or deficiencies in, or failure to perfect or
lapse in perfection of, or avoidance as a fraudulent conveyance or otherwise of, the Liens securing the Senior Lien Obligations,
the subordination of such Liens to any other Liens, or any other circumstance whatsoever, whether or not any Insolvency or Liquidation
Proceeding has been commenced by or against the Company, each Junior Lien Representative and each Junior Lien Collateral Agent,
for itself and on behalf of each other Junior Lien Claimholder represented by it, hereby agrees that:

 

    12 

     

    

 

(a)       any
Lien on the Collateral securing any Senior Lien Obligations now or hereafter held by or on behalf of any Senior Lien Representative,
any Senior Lien Collateral Agent or any Senior Lien Claimholders or any agent or trustee therefor, regardless of how acquired,
whether by grant, possession, statute, operation of law, subrogation or otherwise, shall be senior in all respects and prior to
any Lien on the Collateral securing any Junior Lien Obligations; and

 

(b)       any
Lien on the Collateral securing any Junior Lien Obligations now or hereafter held by or on behalf of any Junior Lien Representative,
any Junior Lien Collateral Agent, any Junior Lien Claimholders or any agent or trustee therefor regardless of how acquired, whether
by grant, possession, statute, operation of law, subrogation or otherwise, shall be junior and subordinate in all respects to all
Liens on the Collateral securing any Senior Lien Obligations. All Liens on the Collateral securing any Senior Lien Obligations
shall be and remain senior in all respects and prior to all Liens on the Collateral securing any Junior Lien Obligations for all
purposes, whether or not such Liens securing any Senior Lien Obligations are subordinated to any Lien securing any other obligation
of the Company or any other Person.

 

Prohibition on Contesting Liens; No Marshaling.
Each Junior Lien Representative and each Junior Lien Collateral Agent, for itself and on behalf of each other Junior Lien Claimholder
represented by it, and each Senior Lien Representative and each Senior Lien Collateral Agent, for itself and on behalf of each
other Senior Lien Claimholder represented by it, agrees that it will not (and hereby waives any right to) directly or indirectly
contest or support any other Person in contesting, in any proceeding (including any Insolvency or Liquidation Proceeding), the
priority, validity, perfection, extent or enforceability of a Lien held, or purported to be held, by or on behalf of any of the
Senior Lien Claimholders in the Senior Lien Collateral or by or on behalf of any of the Junior Lien Claimholders in the Junior
Lien Collateral, as the case may be, or the provisions of this Agreement; provided that nothing in this Agreement shall be construed
to prevent or impair the rights of any Senior Lien Representative, any Senior Lien Collateral Agent or any Senior Lien Claimholder
to enforce this Agreement, including the provisions of this Agreement relating to the priority of the Liens securing the Senior
Lien Obligations as provided in Sections 3.1 and 4.1. Until the Discharge of Senior Lien Obligations, no Junior Lien Representative,
Junior Lien Collateral Agent or Junior Lien Claimholder will assert any marshaling, appraisal, valuation or other similar right
that may otherwise be available to a junior secured creditor.

 

No New Liens. So long as the Discharge
of Senior Lien Obligations has not occurred, whether or not any Insolvency or Liquidation Proceeding has been commenced by or against
the Company, the parties hereto agree that the Company shall not:

 

(a)       grant
or permit any additional Liens on any asset or property to secure any Junior Lien Obligation unless it has granted or concurrently
grants a Lien on such asset or property to secure one or more Series of Senior Lien Obligations, the parties hereto agreeing that
any such Lien shall be subject to Section 3.1 hereof; or

 

(b)       grant
or permit any additional Liens on any asset or property of the Company to secure any Senior Lien Obligations unless it has granted
or concurrently grants a Lien on such asset or property of the Company to secure the Junior Lien Obligations; provided that
this provision will not be violated with respect to any particular Series of Junior Lien Obligations if the applicable Junior Lien
Collateral Agent is given a reasonable opportunity to accept a Lien on any asset or property and such Junior Lien Collateral Agent
states in writing that the Junior Lien Documents in respect thereof prohibit such Junior Lien Collateral Agent from accepting a
Lien on such asset or property or the applicable Junior Lien Collateral Agent otherwise expressly declines to accept a Lien on
such asset or property (any such prohibited or declined Lien with respect to a particular Series of Junior Lien Obligations, a
“Junior Lien Declined Lien”).

 

    13 

     

    

 

If any Junior Lien Representative, any Junior
Lien Collateral Agent or any Junior Lien Claimholder shall hold any Lien on any assets of the Company securing any Junior Lien
Obligations that are not also subject to one or more first-priority Liens securing Senior Lien Obligations under the Senior Lien
Collateral Documents, such Junior Lien Representative, Junior Lien Collateral Agent or Junior Lien Claimholder shall notify the
Senior Lien Representative promptly upon having actual knowledge thereof and, unless the Company shall promptly grant a similar
Lien on such assets of the Company to each Senior Lien Collateral Agent as security for the Senior Lien Obligations represented
by it, such Junior Lien Representative, Junior Lien Collateral Agent and Junior Lien Claimholders shall be deemed to hold and have
held such Lien for the benefit of each Senior Lien Representative, Senior Lien Collateral Agent and the other Senior Lien Claimholders,
other than any Senior Lien Claimholders whose Senior Lien Documents prohibit them from taking such Liens, as security for the Senior
Lien Obligations. To the extent that the foregoing provisions are not complied with for any reason, without limiting any other
rights and remedies available to any one or more Senior Lien Representative, Senior Lien Collateral Agent and the Senior Lien Claimholders,
each Junior Lien Representative and each Junior Lien Collateral Agent, on behalf of each Junior Lien Claimholder represented by
it, agrees that any amounts received by or distributed to any of them pursuant to or as a result of Liens granted in contravention
of this Section 3.3 shall be subject to Section 5.2.

 

Except as provided in the next paragraph,
if any Senior Lien Representative, any Senior Lien Collateral Agent or any Senior Lien Claimholder shall hold any Lien on any assets
or property of the Company securing any Senior Lien Obligations that are not also subject to one or more Liens securing Junior
Lien Obligations under the Junior Lien Collateral Documents, such Senior Lien Representative, Senior Lien Collateral Agent or Senior
Lien Claimholder shall notify each Junior Lien Representative promptly upon having actual knowledge thereof and, unless the Company
shall promptly grant a similar Lien, other than any such Lien that would constitute a Junior Lien Declined Lien, on such assets
or property of the Company to each Junior Lien Collateral Agent as security for the Junior Lien Obligations represented by it,
such Senior Lien Representative, Senior Lien Collateral Agent and Senior Lien Claimholders shall be deemed to hold and have held
such Lien for the benefit of each Junior Lien Representative, Junior Lien Collateral Agent and the other Junior Lien Claimholders
(subject to the priorities set forth herein), other than any Junior Lien Claimholders whose Junior Lien Documents prohibit them
from taking such Liens, as security for the Junior Lien Obligations. To the extent that the foregoing provisions are not complied
with for any reason, without limiting any other rights and remedies available to any one or more Junior Lien Representative, Junior
Lien Collateral Agent and the Junior Lien Claimholders, each Senior Lien Representative and each Senior Lien Collateral Agent,
on behalf of each Senior Lien Claimholder represented by it, agrees that any amounts received by or distributed to any of them
pursuant to or as a result of Liens granted in contravention of this Section 3.3 shall be subject to Section 5.2.

 

Notwithstanding anything in this Agreement
to the contrary, prior to the Discharge of Senior Lien Obligations, cash and cash equivalents may be pledged to secure Senior Lien
Obligations consisting of reimbursement obligations in respect of letters of credit issued pursuant to the Senior Lien Documents
without granting a Lien thereon to secure any other Senior Lien Obligations or any other Junior Lien Obligations.

 

Perfection of Liens. Except for the
arrangements contemplated by Section 5.7, none of the Senior Lien Representatives, Senior Lien Collateral Agents or the Senior
Lien Claimholders shall be responsible for perfecting and maintaining the perfection of Liens with respect to the Collateral for
the benefit of the Junior Lien Representatives, the Junior Lien Collateral Agents or the Junior Lien Claimholders. The provisions
of this Agreement are intended solely to govern the respective Lien priorities as between the Senior Lien Claimholders on the one
hand and the Junior Lien Claimholders on the other hand and such provisions shall not impose on the Senior Lien Representatives,
Senior Lien Collateral Agents, the Senior Lien Claimholders, the Junior Lien Representatives, the Junior Lien Collateral Agents,
the Junior Lien Claimholders or any agent or trustee therefor any obligations in respect of the disposition of proceeds of any
Collateral which would conflict with prior-perfected claims therein in favor of any other Person or any order or decree of any
court or Governmental Authority or any applicable law.

 

Nature of Senior Lien Obligations.
Each Junior Lien Representative and each Junior Lien Collateral Agent, on behalf of itself and each other Junior Lien Claimholder
represented by it, acknowledges that a portion of the Senior Lien Obligations represents, or may in the future represent, debt
that is revolving in nature and that the amount thereof that may be outstanding at any time or from time to time may be increased
or reduced and subsequently reborrowed, and that the terms of the Senior Lien Obligations may be modified, extended or amended
from time to time, and that the aggregate amount of the Senior Lien Obligations may be increased, replaced or refinanced, in each
event, without notice to or consent by the Junior Lien Claimholders and without affecting the provisions hereof. The lien priorities
provided in Section 3.1 shall not be altered or otherwise affected by any such amendment, modification, supplement, extension,
repayment, reborrowing, increase, replacement, renewal, restatement or refinancing of either the Senior Lien Obligations or the
Junior Lien Obligations, or any portion thereof. In addition, as among the Senior Lien Claimholders, their respective rights and
obligations shall be governed by the Senior Lien Intercreditor Agreement which among other things may provide for various levels
of Lien priority and/or payment priority as among the Senior Lien Claimholders without affecting the provisions hereof.

 

    14 

     

    

 

Section 4.Enforcement.

 

4.1       Exercise
of Remedies.

 

(a)       Until
the Discharge of Senior Lien Obligations has occurred, whether or not any Insolvency or Liquidation Proceeding has been commenced
by or against the Company, the Junior Lien Representatives, the Junior Lien Collateral Agents and the Junior Lien Claimholders:

 

(1)       will
not commence or maintain, or seek to commence or maintain, any Collateral Enforcement Action or otherwise exercise any rights or
remedies with respect to the Collateral; provided that any one or more of the Junior Lien Representative and the Junior
Lien Collateral Agent may, in accordance with any relevant Junior Lien Security Document, but is not required to, commence a Collateral
Enforcement Action or otherwise exercise any or all such rights or remedies after the passage of a period of at least 180 days
has elapsed since the later of (i) the date on which a Junior Lien Representative declared the existence of any Event of Default
under (and as defined in) any Junior Lien Documents and demanded the repayment of all the principal amount of any Junior Lien Obligations
thereunder; and (ii) the date on which the Senior Lien Representatives received notice from such Junior Lien Representative
of such declarations of such Event of Default and demand for payment (the “Standstill Period”); provided,
further, that notwithstanding anything herein to the contrary, in no event shall any Junior Lien Representative, any Junior Lien
Collateral Agent or any Junior Lien Claimholder exercise any rights or remedies with respect to the Collateral if, notwithstanding
the expiration of the Standstill Period, any Senior Lien Representative, any Senior Lien Collateral Agent or any applicable Senior
Lien Claimholder(s) shall have commenced and is pursuing a Collateral Enforcement Action or other exercise of its or their rights
or remedies in each case with respect to all or any material portion of the Collateral (prompt written notice of such exercise
to be given to the Junior Lien Representative);

 

(2)       will
not contest, protest or object to (i) any foreclosure proceeding or action brought by any Senior Lien Representative, any
Senior Lien Collateral Agent or any Senior Lien Claimholder or (ii) any other exercise by any Senior Lien Representative,
any Senior Lien Collateral Agent or any Senior Lien Claimholder of any rights and remedies relating to the Collateral under the
Senior Lien Documents or otherwise (including any Collateral Enforcement Action initiated by or supported by any Senior Lien Representative,
any Senior Lien Collateral Agent or any Senior Lien Claimholder); and

 

(3)       subject
to their rights under clause (a)(1) above will not object to the forbearance by any Senior Lien Representative, any Senior
Lien Collateral Agent or any Senior Lien Claimholder from bringing or pursuing any foreclosure proceeding or action or any other
exercise of any rights or remedies relating to the Collateral, in each case so long as any proceeds received by any Senior Lien
Representative in excess of those necessary to achieve a Discharge of Senior Lien Obligations are distributed in accordance with
Section 5.1 hereof and applicable law.

 

(b)       Until
the Discharge of Senior Lien Obligations has occurred, whether or not any Insolvency or Liquidation Proceeding has been commenced
by or against the Company, subject to Section 4.1(a)(1), the Senior Lien Representatives, the Senior Lien Collateral
Agents and the Senior Lien Claimholders shall have the exclusive right to (i) commence and maintain a Collateral Enforcement
Action or otherwise enforce rights, exercise remedies (including set-off, recoupment and the right to credit bid their debt, except
that Junior Lien Representatives shall have the credit bid rights set forth in Section 4.1(c)(6)), and (ii) subject
to Section 5.3, make determinations regarding the release, disposition, or restrictions with respect to the Collateral
without any consultation with or the consent of any Junior Lien Representative, any Junior Lien Collateral Agent or any other Junior
Lien Claimholder; provided that, in each case, any proceeds received by any Senior Lien Representative in excess of those
necessary to achieve a Discharge of Senior Lien Obligations are distributed in accordance with Section 5.1 hereof and
applicable law. In commencing or maintaining any Collateral Enforcement Action or otherwise exercising rights and remedies with
respect to the Collateral, the Senior Lien Representatives, Senior Lien Collateral Agents and the Senior Lien Claimholders may
enforce the provisions of the Senior Lien Documents and exercise remedies thereunder, all in such order and in such manner as they
may determine in the exercise of their sole discretion in compliance with any applicable law and without consultation with any
Junior Lien Representative, any Junior Lien Collateral Agent or any other Junior Lien Claimholder and regardless of whether any
such exercise is adverse to the interest of any Junior Lien Claimholder. Such exercise and enforcement shall include the rights
of an agent appointed by them to sell or otherwise dispose of Collateral upon foreclosure, to incur expenses in connection with
such sale or disposition, and to exercise all the rights and remedies of a secured creditor under the UCC and under Bankruptcy
Law of any applicable jurisdiction.

 

    15 

     

    

 

(c)       Notwithstanding
the foregoing, any Junior Lien Representative, any Junior Lien Collateral Agent, in accordance with any relevant Junior Lien Security
Document, and any other Junior Lien Claimholder may:

 

(1)       file
a claim or statement of interest with respect to the Junior Lien Obligations; provided that an Insolvency or Liquidation
Proceeding has been commenced by or against the Company;

 

(2)       take
any action not adverse to the priority status of the Liens on the Collateral securing the Senior Lien Obligations, or the rights
of any Senior Lien Representative, any Senior Lien Collateral Agent or the Senior Lien Claimholders to exercise remedies in respect
thereof, in order to create, perfect, preserve or protect its Lien on the Collateral;

 

(3)       file
any necessary responsive or defensive pleadings in opposition to any motion, claim, adversary proceeding or other pleading made
by any person objecting to or otherwise seeking the disallowance of the claims of the Junior Lien Claimholders, including any claims
secured by the Collateral, if any, in each case in accordance with the terms of this Agreement;

 

(4)       vote
on any plan of reorganization, arrangement, compromise or liquidation, file any proof of claim, make other filings and make any
arguments and motions that are, in each case, in accordance with the terms of this Agreement, with respect to the Junior Lien Obligations
and the Collateral; provided that no filing of any claim or vote, or pleading related to such claim or vote, to accept or
reject a disclosure statement, plan of reorganization, arrangement, compromise or liquidation, or any other document, agreement
or proposal similar to the foregoing by any Junior Lien Representative, any Junior Lien Collateral Agent or any other Junior Lien
Claimholder, may be inconsistent with the provisions of this Agreement;

 

(5)       exercise
any of its rights or remedies with respect to the Collateral after the termination of the Standstill Period to the extent permitted
by Section 4.1(a)(1); and

 

(6)       bid
for or purchase Collateral at any public, private or judicial foreclosure upon such Collateral initiated by any Senior Lien Representative,
any Senior Lien Collateral Agent or any other Senior Lien Claimholder, or any sale of Collateral during an Insolvency or Liquidation
Proceeding; provided that such bid may not include a “credit bid” in respect of any Junior Lien Obligations
unless the cash proceeds of such bid are otherwise sufficient to cause the Discharge of Senior Lien Obligations.

 

    16 

     

    

 

Each Junior Lien Representative and each
Junior Lien Collateral Agent, on behalf of itself and each other Junior Lien Claimholder represented by it, agrees that it will
not take or receive any Collateral or any proceeds of Collateral in connection with the exercise of any right or remedy (including
set-off and recoupment) with respect to any Collateral in its capacity as a creditor, unless and until the Discharge of Senior
Lien Obligations has occurred, except in connection with any foreclosure that is expressly permitted by Section 4.1(a)(1)
to pursue after the expiration of the Standstill Period to the extent such Junior Lien Representative or such Junior Lien Collateral
Agent and Junior Lien Claimholders represented by it are permitted to retain the proceeds thereof in accordance with Section 5.2
of this Agreement. Without limiting the generality of the foregoing, unless and until the Discharge of Senior Lien Obligations
has occurred, except as expressly provided in Sections 4.1(a), 6.3(b) and this Section 4.1(c), the
sole right of the Junior Lien Representatives, the Junior Lien Collateral Agents and the other Junior Lien Claimholders with respect
to the Collateral is to hold a Lien on the Collateral pursuant to the Junior Lien Collateral Documents for the period and to the
extent granted therein and to receive a share of the proceeds thereof, if any, after the Discharge of Senior Lien Obligations has
occurred.

 

(d)       Subject
to Sections 4.1(a) and (c) and Section 6.3(b):

 

(1)       each
Junior Lien Representative and each Junior Lien Collateral Agent, for itself and on behalf of each other Junior Lien Claimholder
represented by it, agrees that such Junior Lien Representative or such Junior Lien Collateral Agent and such Junior Lien Claimholders
represented by it will not take any action that would hinder any exercise of remedies under the Senior Lien Documents or that is
otherwise prohibited hereunder, including any sale, lease, exchange, transfer or other disposition of the Collateral, whether by
foreclosure or otherwise;

 

(2)       each
Junior Lien Representative and each Junior Lien Collateral Agent, for itself and on behalf of each other Junior Lien Claimholder
represented by it, hereby waives any and all rights such Junior Lien Representative or such Junior Lien Collateral Agent and such
Junior Lien Claimholders represented by it may have as a junior lien creditor or otherwise to object to the manner in which any
Senior Lien Representative, any Senior Lien Collateral Agent or any other Senior Lien Claimholder seeks to enforce or collect the
Senior Lien Obligations or Liens securing the Senior Lien Obligations granted in any of the Senior Lien Collateral undertaken in
accordance with this Agreement, regardless of whether any action or failure to act by or on behalf of any Senior Lien Representative,
any Senior Lien Collateral Agent or any other Senior Lien Claimholder is adverse to the interest of any Junior Lien Claimholder;
and

 

(3)       each
Junior Lien Representative and each Junior Lien Collateral Agent, for itself and on behalf of each other Junior Lien Claimholder
represented by it, hereby acknowledges and agrees that no covenant, agreement or restriction contained in any Junior Lien Documents
(other than this Agreement) shall be deemed to restrict in any way the rights and remedies of any Senior Lien Representative, any
Senior Lien Collateral Agent or any other Senior Lien Claimholder with respect to the Collateral as set forth in this Agreement
and the Senior Lien Documents.

 

(e)       Except
as specifically set forth in this Agreement, the Junior Lien Collateral Agents and the other Junior Lien Claimholders may exercise
rights and remedies as unsecured creditors against the Company that has guaranteed or granted Liens to secure the Junior Lien Obligations
in accordance with the terms of the Junior Lien Documents and applicable law (other than initiating or joining in an involuntary
case or proceeding under any Insolvency or Liquidation Proceeding with respect to the Company); provided that in the event
that any Junior Lien Claimholder becomes a judgment Lien creditor in respect of Collateral as a result of its enforcement of its
rights as an unsecured creditor with respect to the Junior Lien Obligations, such judgment Lien shall be subject to the terms of
this Agreement for all purposes (including in relation to the Senior Lien Obligations) in the same manner as the other Liens securing
the Junior Lien Obligations are subject to this Agreement.

 

(f)       Except
as specifically set forth in Sections 4.1(a) and (d), nothing in this Agreement shall prohibit the receipt by
any Junior Lien Representative, any Junior Lien Collateral Agent or any other Junior Lien Claimholder of the required payments
of interest, principal and other amounts owed in respect of the Junior Lien Obligations so long as such receipt is not the direct
or indirect result of the exercise by any Junior Lien Representative, any Junior Lien Collateral Agent or any other Junior Lien
Claimholder of rights or remedies as a secured creditor (including set-off and recoupment) or enforcement in contravention of this
Agreement of any Lien held by any of them or as a result of any other violation by any Junior Lien Claimholder of the express terms
of this Agreement. Nothing in this Agreement impairs or otherwise adversely affects any rights or remedies any Senior Lien Representative,
any Senior Lien Collateral Agent or other Senior Lien Claimholder may have with respect to the Senior Lien Collateral.

 

    17 

     

    

 

Actions Upon Breach; Specific Performance.
If any Junior Lien Claimholder, in contravention of the terms of this Agreement, in any way takes, attempts to or threatens to
take any action with respect to the Collateral (including any attempt to realize upon or enforce any remedy with respect to this
Agreement), or fails to take any action required by this Agreement, this Agreement shall create an irrebutable presumption and
admission by such Junior Lien Claimholder that relief against such Junior Lien Claimholder by injunction, specific performance
and/or other appropriate equitable relief is necessary to prevent irreparable harm to the Senior Lien Claimholders, it being understood
and agreed by each Junior Lien Representative and each Junior Lien Collateral Agent, on behalf of each Junior Lien Claimholder
represented by it, that (i) the Senior Lien Claimholders’ damages from actions of any Junior Lien Claimholder may at
that time be difficult to ascertain and may be irreparable and (ii) each Junior Lien Claimholder waives any defense that either
or both the Company and the Senior Lien Claimholders cannot demonstrate either or both damage and be made whole by the awarding
of damages. Each of the Senior Lien Representatives and Senior Lien Collateral Agents may demand specific performance of this Agreement.
Each Junior Lien Representative and each Junior Lien Collateral Agent, on behalf of itself and each other Junior Lien Claimholder
represented by it, hereby irrevocably waives any defense based on the adequacy of a remedy at law and any other defense which might
be asserted to bar the remedy of specific performance in any action which may be brought by any Senior Lien Representative, any
Senior Lien Collateral Agent or any other Senior Lien Claimholder. No provision of this Agreement shall constitute or be deemed
to constitute a waiver by any Senior Lien Representative or any Senior Lien Collateral Agent on behalf of itself and each other
Senior Lien Claimholder represented by it, of any right to seek damages from any Person in connection with any breach or alleged
breach of this Agreement.

 

Section 5.Payments.

 

Application of Proceeds. So long
as the Discharge of Senior Lien Obligations has not occurred, whether or not any Insolvency or Liquidation Proceeding has been
commenced by or against the Company, any Collateral or any proceeds thereof, Restricted Assets or any proceeds thereof or Sale
Proceeds received in connection with any Collateral Enforcement Action or other exercise of remedies by any Senior Lien Representative,
any Senior Lien Collateral Agent or any Senior Lien Claimholder, shall be applied by the Senior Lien Collateral Agents or the Senior
Lien Representatives, as applicable, to the Senior Lien Obligations in such order as specified in the relevant Senior Lien Documents
and, if then in effect, the Senior Lien Intercreditor Agreement (or shall otherwise be turned over to the applicable party in accordance
with the other Intercreditor Agreements); provided, that any non-cash Collateral or non-cash proceeds may be held by the applicable
Senior Lien Collateral Agent as Collateral (or so turned over) unless the failure to apply (or turn over) such amounts would be
commercially unreasonable. Upon the Discharge of Senior Lien Obligations, each Senior Lien Collateral Agent shall (x) unless
a Discharge of Junior Lien Obligations has already occurred, deliver any remaining proceeds of Collateral, Restricted Assets and
Sale Proceeds held by it to the Junior Lien Collateral Agent (unless the Senior Lien Collateral Agent is required to deliver such
items to another party in accordance with another Intercreditor Agreement), to be applied by the Junior Lien Collateral Agent and
the other Junior Lien Collateral Agents or Junior Lien Representatives, as applicable, to the applicable Junior Lien Obligations
in such order as specified in the applicable Junior Lien Documents and (y) if a Discharge of Junior Lien Obligations has already
occurred, deliver such proceeds of Collateral, Restricted Assets and Sale Proceeds to the Company or to whomever may be lawfully
entitled to receive the same. Without limiting the generality of the foregoing, it is the intention of the parties hereto that
no amount of any Sale Proceeds will in any event be allocated to any Restricted Assets, and no Junior Lien Representative, Junior
Lien Collateral Agent or other Junior Lien Claimholder will, in any forum (including in any Insolvency or Liquidation Proceeding),
assert that any amount of any Sale Proceeds should be allocated to any Restricted Assets.

 

5.2       Payments
Over.

 

(a)       So
long as the Discharge of Senior Lien Obligations has not occurred, whether or not any Insolvency or Liquidation Proceeding has
been commenced by or against the Company, any Collateral or any proceeds thereof, Restricted Assets or proceeds thereof and all
Sale Proceeds (including assets or proceeds subject to Liens referred to in the second to last paragraph of Section 3.3
and any assets or proceeds subject to Liens that have been avoided or otherwise invalidated) received by any Junior Lien Representative,
Junior Lien Collateral Agent or any other Junior Lien Claimholder in connection with any Collateral Enforcement Action or other
exercise of any right or remedy relating to the Collateral or the Restricted Assets, in all cases shall be segregated and held
in trust and forthwith paid over to the Senior Lien Collateral Agent for the benefit of the Senior Lien Claimholders in the same
form as received, with any necessary endorsements (which endorsements shall be without recourse and without any representations
or warranties) or as a court of competent jurisdiction may otherwise direct. The Senior Lien Collateral Agent is hereby authorized
to make any such endorsements as agent for the Junior Lien Representatives, Junior Lien Collateral Agents or any such other Junior
Lien Claimholder. This authorization is coupled with an interest and is irrevocable until the Discharge of Senior Lien Obligations.

 

    18 

     

    

 

(b)       So
long as the Discharge of Senior Lien Obligations has not occurred, if in any Insolvency or Liquidation Proceeding any Junior Lien
Representative, any Junior Lien Collateral Agent or any other Junior Lien Claimholder shall receive any distribution of money or
other property in respect of the Collateral, Restricted Assets or Sale Proceeds (including any assets or proceeds subject to Liens
that have been avoided or otherwise invalidated), such money or other property shall be segregated and held in trust and forthwith
paid over to the Senior Lien Collateral Agent for the benefit of the Senior Lien Claimholders in the same form as received, with
any necessary endorsements (which endorsements shall be without recourse and without any representations or warranties). Any Lien
received by any Junior Lien Representative, any Junior Lien Collateral Agent or any other Junior Lien Claimholder in respect of
any of the Junior Lien Obligations in any Insolvency or Liquidation Proceeding shall be subject to the terms of this Agreement.

 

5.3       Releases.

 

(a)       If
in connection with any Collateral Enforcement Action by any Senior Lien Representative or any Senior Lien Collateral Agent or any
other exercise of any Senior Lien Representative’s or any Senior Lien Collateral Agent’s remedies in respect of the
Collateral, in each case prior to the Discharge of Senior Lien Obligations, such Senior Lien Collateral Agent, for itself or on
behalf of any of the Senior Lien Claimholders represented by it, releases any of its Liens on any part of the Collateral, then
the Liens, if any, of each Junior Lien Collateral Agent, for itself or for the benefit of the Junior Lien Claimholders, on such
Collateral, shall be automatically, unconditionally and simultaneously released. Each Junior Lien Representative and each Junior
Lien Collateral Agent, for itself or on behalf of any Junior Lien Claimholder represented by it, shall, within a reasonable time
following such request, execute and deliver to the Senior Lien Representatives, Senior Lien Collateral Agents or the Company, such
termination statements, releases and other documents as any Senior Lien Representative, Senior Lien Collateral Agent or the Company
may request in writing to effectively confirm the foregoing releases, provided that the Junior Lien Representative and Junior
Lien Collateral Agent shall not be required to take any action if such actions would violate applicable law or court order.

 

(b)       If
in connection with any sale, lease, exchange, transfer or other disposition of any Collateral by the Company (collectively, a “Disposition”)
permitted under the terms of the Senior Lien Documents and not expressly prohibited under the terms of the Junior Lien Documents
(other than in connection with a Collateral Enforcement Action or other exercise of any one or more Senior Lien Representative’s
and Senior Lien Collateral Agent’s remedies in respect of the Collateral, which shall be governed by Section 5.3(a)
above above), any Senior Lien Collateral Agent, for itself or on behalf of any Senior Lien Claimholder represented by it, releases
any of its Liens on any part of the Collateral, other than (A) in connection with, or following, the Discharge of Senior Lien
Obligations or (B) after the occurrence and during the continuance of any Event of Default under (and as defined in) any Junior
Lien Documents, then the Liens, if any, of each Junior Lien Collateral Agent, for itself or for the benefit of the Junior Lien
Claimholders represented by it, on such Collateral shall be automatically, unconditionally and simultaneously released. Each Junior
Lien Representative and each Junior Lien Collateral Agent, for itself and on behalf of each other Junior Lien Claimholder represented
by it, shall, promptly execute and deliver to the Senior Lien Representatives, the Senior Lien Collateral Agents or the Company
such termination statements, releases and other documents as any Senior Lien Representative, Senior Lien Collateral Agent or the
Company may request to effectively confirm such release, provided that the Junior Lien Representative and Junior Lien Collateral
Agent shall not be required to take any action if such actions would violate applicable law or court order.

 

    19 

     

    

 

(c)       Until
the Discharge of Senior Lien Obligations occurs, each Junior Lien Representative and each Junior Lien Collateral Agent, for itself
and on behalf of each other Junior Lien Claimholder represented by it, hereby irrevocably constitutes and appoints the Senior Lien
Collateral Agent and any officer or agent of the Senior Lien Collateral Agent, 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 Junior Lien Representative, such
Junior Lien Collateral Agent and such Junior Lien Claimholders or in the Senior Lien Collateral Agent’s own name, from time
to time in the Senior Lien Collateral Agent’s discretion, for the purpose of carrying out the terms of this Section 5.3,
to take any and all appropriate action and to execute any and all documents and instruments which may be necessary to accomplish
the purposes of this Section 5.3, including any endorsements or other instruments of transfer or release. This power
is coupled with an interest and is irrevocable until the Discharge of Senior Lien Obligations.

 

(d)       Until
the Discharge of Senior Lien Obligations occurs, to the extent that any Senior Lien Collateral Agent, any Senior Lien Representative
or Senior Lien Claimholders (i) has released any Lien on Collateral and any such Liens are later reinstated or (ii) obtains
any new Liens from the Company, then each Junior Lien Collateral Agent, for itself and for the Junior Lien Claimholders represented
by it, shall be granted a Lien on any such Collateral (except to the extent such Lien represents a Junior Lien Declined Lien with
respect to the Junior Lien Debt represented by such Junior Lien Collateral Agent), subject to the lien subordination provisions
of this Agreement, and each Junior Lien Representative, for itself and for the Junior Lien Claimholders represented by it, shall
be granted an additional lien.

 

Insurance. Unless and until the Discharge
of Senior Lien Obligations has occurred, the Senior Lien Representatives, the Senior Lien Collateral Agents and the other Senior
Lien Claimholders shall have the sole and exclusive right, subject to the rights of the Company under the Senior Lien Documents,
to adjust settlement for any insurance policy covering the Collateral in the event of any loss thereunder and to approve any award
granted in any condemnation or similar proceeding (or any deed in lieu of condemnation) affecting the Collateral. Subject to the
rights of the Company under the Senior Lien Documents, all proceeds of any such policy and any such award (or any payments with
respect to a deed in lieu of condemnation) if in respect of the Collateral shall be applied in the order of priority set forth
in Section 5.1. Until the Discharge of Senior Lien Obligations has occurred, if any Junior Lien Representative, any Junior
Lien Collateral Agent or any other Junior Lien Claimholder shall, at any time, receive any proceeds of any such insurance policy
or any such award or payment in contravention of this Agreement, then it shall segregate and hold in trust and forthwith pay such
proceeds over to the Senior Lien Collateral Agent in accordance with the terms of Section 5.2.

 

5.5       Amendments
to Senior Lien Documents and Junior Lien Documents.

 

(a)       The
Senior Lien Documents of any Series may be amended, restated, amended and restated, supplemented or otherwise modified from time
to time in accordance with their terms and the Senior Lien Claims of any Series may be Refinanced subject to Section 5.8
and Section 8.7, in each case, without notice to, or the consent of, any Junior Lien Representative, any Junior Lien
Collateral Agent or any other Junior Lien Claimholder, all without affecting the lien subordination or other provisions of this
Agreement; provided that any such amendment, supplement or modification or Refinancing is not inconsistent with the terms
of this Agreement and, in the case of a Refinancing, the holders of such Refinancing debt or their agent bind themselves in a writing
addressed to each Junior Lien Collateral Agent to the terms of this Agreement.

 

(b)       The
Junior Lien Documents may be amended, restated, amended and restated, supplemented or otherwise modified from time to time in accordance
with their terms and the Junior Lien Debt of any Series may be Refinanced in full but not in part subject to Section 5.8
and Section 8.7, in each case, without notice to, or the consent of, any Senior Lien Representative, any Senior Lien
Collateral Agent or any other Senior Lien Claimholder, all without affecting the lien subordination or other provisions of this
Agreement, provided that any such amendment, restatement, supplement or modification or Refinancing is not inconsistent
with the terms of this Agreement and, in the case of any Refinancing, the holders of such Refinancing debt or their agent bind
themselves in a writing addressed to each Senior Lien Collateral Agent to the terms of this Agreement; and provided further that
any such amendment, restatement, supplement, modification or Refinancing shall not, without the consent of each Senior Lien Representative:

 

    20 

     

    

 

(1)       increase
the then-outstanding principal amount of the Junior Lien Debt of that Series, provided, that the foregoing shall not restrict any
increases in principal resulting from any “payment in kind”;

 

(2)       increase
the “Applicable Margin” or similar component of the interest rate or yield provisions applicable to the Indebtedness
outstanding under the Junior Lien Documents of that Series in a manner that would result in the total yield thereon to exceed by
more than [3]% per annum the total yield on Indebtedness thereunder as in effect on the date such Indebtedness became Junior
Lien Debt (excluding increases resulting from the accrual of interest at the default rate);

 

(3)       amend
or otherwise modify any “Default” or “Event of Default” (as each such term is defined in the Junior Lien
Documents for that Series) thereunder in a manner adverse to the loan parties thereunder;

 

(4)       accelerate
any date upon which a scheduled payment of principal or interest is due, or otherwise decrease the weighted average life to maturity;

 

(5)       modify
(or undertake any action having the effect of a modification of) the mandatory prepayment provisions of the Junior Lien Documents
for that Series in a manner adverse to the Senior Lien Claimholders; or

 

(6)       increase
materially the obligations of the obligor thereunder or confer any additional material rights of the Junior Lien Claimholders (or
a representative on their behalf) which would be adverse to any Senior Lien Claimholders.

 

(c)       In
the event any Senior Lien Collateral Agent or the applicable Senior Lien Claimholders and the Company enter into any amendment,
waiver or consent in respect of any of the Senior Lien Collateral Documents for the purpose of adding to, or deleting from, or
waiving or consenting to any departures from any provisions of, any Senior Lien Collateral Document or changing in any manner the
rights of the applicable Senior Lien Collateral Agent, Senior Lien Claimholders, or the Company thereunder, then such amendment,
waiver or consent shall apply automatically to any comparable provision of a Junior Lien Collateral Document without the consent
of any Junior Lien Representative, Junior Lien Collateral Agent or other Junior Lien Claimholder and without any action by any
Junior Lien Representative, any Junior Lien Collateral Agent, any other Junior Lien Claimholder, or the Company, provided
that:

 

(1)       no
such amendment, waiver or consent shall have the effect of:

 

(A)       removing
assets subject to the Lien of the Junior Lien Collateral Documents, except to the extent that a release of such Lien is permitted
or required by Section 5.3 and provided that there is a corresponding release of the Liens securing any Senior Lien
Obligations;

 

(B)       imposing
duties on any Junior Lien Collateral Agent or any Junior Lien Representative without its consent;

 

(C)       permitting
other Liens on the Collateral not permitted under the terms of the Junior Lien Documents or Section 6 hereof; or

 

(D)       being
prejudicial to the interests of the Junior Lien Claimholders to a materially greater extent than the Senior Lien Claimholders (other
than by virtue of their relative priority and the rights and obligations hereunder); and

 

    21 

     

    

 

(2)       notice
of such amendment, waiver or consent shall have been given to each Junior Lien Collateral Agent within ten (10) Business Days
after the effective date of such amendment, waiver or consent.

 

Confirmation of Subordination in Junior
Lien Collateral Documents. The Company agrees that each Junior Lien Collateral Document shall include the following language
(or language to similar effect approved by the Senior Lien Collateral Agent):

 

“Notwithstanding anything herein to the contrary,
the lien and security interest granted to the [collateral agent] pursuant to this Agreement and the exercise of any right or remedy
by the [collateral agent] hereunder are subject to the provisions of the Lien Subordination and Intercreditor Agreement, dated
as of [                    ]
(as amended, restated, amended and restated, supplemented or otherwise modified from time to time, the “Lien Subordination
and Intercreditor Agreement”), among [                    ],
as Initial Senior Lien Representative, [        ], as Initial Senior Lien Collateral Agent,
[                    ], as
Initial Junior Lien Representative, [            ], as Initial Junior
Lien Collateral Agent and certain other persons party to the Lien Subordination and Intercreditor Agreement or that may become
party thereto from time to time. In the event of any conflict between the terms of the Lien Subordination and Intercreditor Agreement
and this Agreement, the terms of the Lien Subordination and Intercreditor Agreement shall govern and control.”

 

5.7       Gratuitous
Bailee/Agent for Perfection; Rights of Initial Senior Collateral Agent and Initial Senior Lien Representative.

 

(a)       Each
Senior Lien Collateral Agent agrees to hold that part of the Collateral that is in its possession or control (or in the possession
or control of its agents or bailees) to the extent that possession or control thereof is taken to perfect a Lien thereon under
the UCC (such Collateral being the “Pledged Collateral”) as collateral agent for the Senior Lien Claimholders
and gratuitous bailee for the Junior Lien Collateral Agents (such bailment being intended, among other things, to satisfy the requirements
of Sections 8-106(d)(3), 8-301(a)(2) and 9-313(c) of the UCC) and any assignee thereof solely for the purpose of perfecting
the security interest granted under the Senior Lien Documents and the Junior Lien Documents, respectively, subject to the terms
and conditions of this Section 5.7. Solely with respect to any deposit accounts under the control (within the meaning
of Section 9-104 of the UCC) of any Senior Lien Collateral Agent, such Senior Lien Collateral Agent hereby agrees to also
hold control over such deposit accounts as gratuitous agent for the Junior Lien Collateral Agents, subject to the terms and conditions
of this Section 5.7.

 

(b)       No
Senior Lien Collateral Agent shall have any obligation whatsoever to the Junior Lien Representatives, the Junior Lien Collateral
Agents or the Junior Lien Claimholders to ensure that the Pledged Collateral is genuine or owned by the Company, to perfect the
security interests of the Junior Lien Collateral Agents or other Junior Lien Claimholders or to preserve rights or benefits of
any Person except as expressly set forth in this Section 5.7. The duties or responsibilities of any Senior Lien Collateral
Agent under this Section 5.7 shall be limited solely to holding the Pledged Collateral as gratuitous bailee (and with
respect to deposit accounts, agent) in accordance with this Section 5.7 and delivering the Pledged Collateral upon
a Discharge of Senior Lien Obligations as provided in paragraph (d) below.

 

(c)       No
Senior Lien Collateral Agent or any other Senior Lien Claimholder shall have by reason of the Senior Lien Collateral Documents,
the Junior Lien Collateral Documents, this Agreement or any other document, a fiduciary relationship in respect of any Junior Lien
Representative or any other Junior Lien Claimholder and the Junior Lien Representatives, the Junior Lien Collateral Agents and
the Junior Lien Claimholders hereby waive and release the Senior Lien Collateral Agents and the other Senior Lien Claimholders
from all claims and liabilities arising pursuant to any Senior Lien Collateral Agent’s role under this Section 5.7
as gratuitous bailee and gratuitous agent with respect to the Pledged Collateral. It is understood and agreed that the interests
of the Senior Lien Collateral Agents and the other Senior Lien Claimholders, on the one hand, and the Junior Lien Representatives,
the Junior Lien Collateral Agents and the other Junior Lien Claimholders on the other hand, may differ and the Senior Lien Collateral
Agents and the other Senior Lien Claimholders shall be fully entitled to act in their own interest without taking into account
the interests of the Junior Lien Representatives, the Junior Lien Collateral Agents or other Junior Lien Claimholders.

 

    22 

     

    

 

(d)       Upon
the Discharge of Senior Lien Obligations, each Senior Lien Collateral Agent shall deliver the remaining Pledged Collateral in its
possession (if any) together with any necessary endorsements (which endorsement shall be without recourse and without any representation
or warranty), (x) unless a Discharge of Junior Lien Obligations has not already occurred, to the Junior Lien Collateral Agent
(unless the Senior Lien Collateral Agent is required to deliver such items to another party in accordance with another Intercreditor
Agreement) and (y) if a Discharge of Junior Lien Obligations has already occurred, to the Company or to whomever may be lawfully
entitled to receive the same. Following the Discharge of Senior Lien Obligations, each Senior Lien Collateral Agent further agrees
to take all other action required or requested by any Junior Lien Collateral Agent at the expense of the Company in connection
with the Junior Lien Collateral Agents obtaining a first-priority security interest in the Collateral (subject to the rights of
other parties in accordance with the other Intercreditor Agreements). After the Discharge of Senior Lien Obligations has occurred,
upon the Discharge of Junior Lien Obligations, each Junior Lien Collateral Agent shall deliver the remaining Pledged Collateral
in its possession (if any) together with any necessary endorsements (which endorsement shall be without recourse and without any
representation or warranty, to the Company or to whomever may be lawfully entitled to receive the same.

 

(e)       Upon
execution of this Agreement, each Junior Lien Representative and Junior Lien Collateral Agent shall, promptly following such requirements
or requests, (x) enter into such documents and agreements as the Company or the Initial Senior Lien Representative and/or
the Initial Senior Lien Collateral Agent or Initial Senior Lien Representative shall reasonably request in order to provide to
the Initial Senior Lien Collateral Agent and Initial Senior Lien Representative the rights contemplated hereby, in each case consistent
in all material respects with the terms of this Agreement and (y) deliver to such Initial Senior Lien Collateral Agent any
Pledged Collateral held by it together with any necessary endorsements (or otherwise allow such Initial Senior Lien Collateral
Agent to obtain control of such Pledged Collateral), provided that the Junior Lien Representative or Junior Lien Collateral
Agent shall not be required to take any action if such actions would violate applicable law or court order.

 

When Discharge of Obligations Deemed
to Not Have Occurred. If, at any time after the Discharge of Senior Lien Obligations has occurred or contemporaneously therewith,
the Company enters into any Refinancing of any Senior Lien Documents evidencing a Senior Lien Obligation, then such Discharge of
Senior Lien Obligations shall automatically be deemed not to have occurred for all purposes of this Agreement (other than with
respect to any actions taken as a result of the occurrence of such first Discharge of Senior Lien Obligations), and, from and after
the date on which the Additional Senior Lien Representative and Additional Senior Lien Collateral Agent in respect of such Refinancing
each becomes a party to this Agreement in accordance with Section 8.7(b), the obligations under such Refinancing of the applicable
Senior Lien Documents shall automatically be treated as Senior Lien Obligations for all purposes of this Agreement, including for
purposes of the Lien priorities and rights in respect of Collateral set forth herein, and the Additional Senior Lien Representative
and the Additional Senior Lien Collateral Agent under such new Senior Lien Documents shall be a Senior Lien Representative and
Senior Lien Collateral Agent, respectively, for all purposes of this Agreement. Upon receipt of a Designation from the Company
in accordance with Section 8.7(b)(2) of this Agreement, each Junior Lien Representative and Junior Lien Collateral Agent shall,
promptly following such requests, (x) enter into such documents and agreements (including amendments or supplements to this
Agreement) as the Company or any one or more such Additional Senior Lien Representative and such Additional Senior Lien Collateral
Agent shall reasonably request in order to provide to such Additional Senior Lien Representative and such Additional Senior Lien
Collateral Agent the rights contemplated hereby, in each case consistent in all material respects with the terms of this Agreement
and (y) deliver to such Additional Senior Lien Collateral Agent any Pledged Collateral held by it together with any necessary
endorsements (or otherwise allow such Additional Senior Lien Collateral Agent to obtain control of such Pledged Collateral), provided
that the Junior Lien Representative and Junior Lien Collateral Agent shall not be required to take any action if such actions would
violate applicable law or court order. If the Additional Senior Lien Obligations under the Additional Senior Lien Documents in
respect of such Refinancing are secured by assets of the Company constituting Collateral that do not also secure the Junior Lien
Obligations, then the Junior Lien Obligations shall be secured at such time by a junior-priority Lien on such assets to the same
extent provided in the Junior Lien Collateral Documents and this Agreement except to the extent, with respect to any Series of
Junior Lien Obligations, such Lien on such assets constitutes a Junior Lien Declined Lien.

 

    23 

     

    

 

Section 6.Insolvency
or Liquidation Proceedings.

 

Finance and Sale Issues. Until the
Discharge of Senior Lien Obligations has occurred, if the Company shall be subject to any Insolvency or Liquidation Proceeding
and any Senior Lien Representative shall desire to permit the use of “Cash Collateral” (as such term is defined in
Section 363(a) of the Bankruptcy Code) of the Company on which such Senior Lien Representative, such Senior Lien Collateral
Agent or any other creditor has a Lien, or to permit the Company to obtain financing, whether from the Senior Lien Claimholders
or any other Person under Section 364 of the Bankruptcy Code or any similar Bankruptcy Law (“DIP Financing”),
then each Junior Lien Representative and each Junior Lien Collateral Agent, for itself and on behalf of each other Junior Lien
Claimholder represented by it, will not object to such Cash Collateral use or DIP Financing (including any proposed orders for
either or both such Cash Collateral use and DIP Financing which are acceptable to any Senior Lien Representative) and to the extent
the Liens securing the Senior Lien Obligations are subordinated to or pari passu with such DIP Financing, each Junior Lien Collateral
Agent will subordinate its Liens in the Collateral to the Liens securing such DIP Financing (and all Obligations relating thereto)
and each Junior Lien Representative and each Junior Lien Collateral Agent, for itself and on behalf of each other Junior Lien Claimholder
represented by it, will not request adequate protection or any other relief in connection therewith (except as expressly agreed
by the Senior Lien Representative or to the extent permitted by Section 6.3); provided that the Junior Lien Representatives
and the other Junior Lien Claimholders retain the right to object to any ancillary agreements or arrangements regarding Cash Collateral
use or the DIP Financing that are materially prejudicial to their interests. No Junior Lien Claimholder may provide DIP Financing
to the Company secured by Liens equal or senior in priority to the Liens securing any Senior Lien Obligations. Each Junior Lien
Representative and each Junior Lien Collateral Agent, for itself and on behalf of each other Junior Lien Claimholder represented
by it, agrees that it will not seek consultation rights in connection with, and it will not object to or oppose, a motion to sell,
liquidate or otherwise dispose of Collateral under Section 363 of the Bankruptcy Code if the requisite Senior Lien Claimholders
have consented to such sale, liquidation or other disposition. Each Junior Lien Representative and each Junior Lien Collateral
Agent, for itself and on behalf of each other Junior Lien Claimholder represented by it, further agrees that it will not directly
or indirectly oppose or impede entry of any order in connection with such sale, liquidation or other disposition, including orders
to retain professionals or set bid procedures in connection with such sale, liquidation or disposition, if the requisite Senior
Lien Claimholders have consented to (i) such retention of professionals and bid procedures in connection with such sale, liquidation
or disposition of such assets and (ii) the sale, liquidation or disposition of such assets, in which event the Junior Lien
Claimholders will be deemed to have consented to the sale or disposition of Collateral pursuant to Section 363(f) of the Bankruptcy
Code and such order does not materially impair the rights of the Junior Lien Claimholders under Section 363(k) of the Bankruptcy
Code.

 

Notwithstanding any other provision hereof
to the contrary, each Junior Lien Representative and each Junior Lien Collateral Agent, for itself and on behalf of each other
Junior Lien Claimholder represented by it, agrees that (A) without the consent of the Senior Lien Claimholders, none of such
Junior Lien Representative or such Junior Lien Collateral Agent, the Junior Lien Claimholders represented by it or any agent or
the trustee on behalf of any of them shall, for any purpose during any Insolvency or Liquidation Proceeding or otherwise, support,
endorse, propose or submit, whether directly or indirectly, any valuation of the Company or their respective assets that allocates
or ascribes any value whatsoever to any of the Restricted Assets and (B) without the consent of the Senior Lien Claimholders,
none of such Junior Lien Representative or such Junior Lien Collateral Agent, the Junior Lien Claimholders represented by it or
any agent or trustee on behalf of any of them shall for any purpose during any Insolvency or Liquidation Proceeding or otherwise,
challenge, dispute or object, whether directly or indirectly, to any valuation of the Company or its assets, or otherwise take
any position with respect to such valuation, that is proposed, supported or otherwise arises in any Insolvency or Liquidation Proceeding,
on grounds that such valuation does not allocate or ascribe adequate or appropriate value to any of the Restricted Assets.

 

Relief from the Automatic Stay. Until
the Discharge of Senior Lien Obligations has occurred, each Junior Lien Representative and each Junior Lien Collateral Agent, for
itself and on behalf of each other Junior Lien Claimholder represented by it, agrees that none of them shall: (i) seek (or
support any other Person seeking) relief from the automatic stay or any other stay in any Insolvency or Liquidation Proceeding
in respect of the Collateral or the Restricted Assets, without the prior written consent of all of the Senior Lien Representatives,
unless a motion for adequate protection permitted under Section 6.3 has been denied by a bankruptcy court or (ii) oppose
(or support any other Person in opposing) any request by any Senior Lien Representative or Senior Lien Collateral Agent for relief
from such stay.

 

    24 

     

    

 

6.3       Adequate
Protection.

 

(a)       Each
Junior Lien Representative and each Junior Lien Collateral Agent, for itself and on behalf of each other Junior Lien Claimholder
represented by it, agrees that none of them shall contest (or support any other Person contesting):

 

(1)       any
request by any Senior Lien Representative, any Senior Lien Collateral Agent or other Senior Lien Claimholder for adequate protection
under any Bankruptcy Law; or

 

(2)       any
objection by any Senior Lien Representative, any Senior Lien Collateral Agent or other Senior Lien Claimholder to any motion, relief,
action or proceeding based on such Senior Lien Representative, Senior Lien Collateral Agent or Senior Lien Claimholder claiming
a lack of adequate protection.

 

(b)       Notwithstanding
the foregoing provisions in this Section 6.3, in any Insolvency or Liquidation Proceeding:

 

(1)       if
the Senior Lien Claimholders (or any subset thereof) are granted adequate protection in the form of additional collateral in connection
with any  Cash Collateral use or DIP Financing by the Company (except to the extent such
adequate protection is granted to the Senior Lien Representative, Senior Lien Collateral Agent or Senior Lien Claimholder in consideration
of Senior Lien Collateral that does not constitute Collateral), then each Junior Lien Collateral Agent, for itself or on behalf
of any other Junior Lien Claimholder represented by it, may seek or request adequate protection in the form of a Lien on such additional
collateral, which Lien will be subordinated to the Liens securing the Senior Lien Obligations and such Cash Collateral use or DIP
Financing (and all Obligations relating thereto) on the same basis as the other Liens securing the Junior Lien Obligations are
so subordinated to the Senior Lien Obligations under this Agreement; and

 

(2)       the
Junior Lien Representatives, the Junior Lien Collateral Agents and Junior Lien Claimholders shall only be permitted to seek adequate
protection with respect to their rights in the Collateral in any Insolvency or Liquidation Proceeding in the form of (A) additional
collateral; provided that as adequate protection for the Senior Lien Obligations, each Senior Lien Collateral Agent, on
behalf of the Senior Lien Claimholders represented by it, is also granted a Lien on such additional collateral, which Lien shall
be senior to any Lien of the Junior Lien Representatives, the Junior Lien Collateral Agents and the Junior Lien Claimholders on
such additional collateral; (B) replacement Liens on the Collateral; provided that as adequate protection for the Senior
Lien Obligations, each Senior Lien Collateral Agent, on behalf of the Senior Lien Claimholders represented by it, is also granted
replacement Liens on the Collateral, which Liens shall be senior to the Liens of the Junior Lien Representatives, the Junior Lien
Collateral Agents and the Junior Lien Claimholders on the Collateral; (C) an administrative expense claim; provided
that as adequate protection for the Senior Lien Obligations, each Senior Lien Representative, on behalf of the Senior Lien Claimholders
represented by it, is also granted an administrative expense claim which is senior and prior to the administrative expense claim
of the Junior Lien Representatives and the other Junior Lien Claimholders; and (D) cash payments with respect to interest
on the Junior Lien Obligations; provided that (1) as adequate protection for the Senior Lien Obligations, each Senior
Lien Representative, on behalf of the Senior Lien Claimholders represented by it, is also granted cash payments with respect to
interest on the Senior Lien Obligation represented by it and (2) such cash payments do not exceed an amount equal to the interest
accruing on the principal amount of Junior Lien Obligations outstanding on the date such relief is granted at the interest rate
under the applicable Junior Lien Documents and accruing from the date the applicable Junior Lien Representative is granted such
relief. If any Junior Lien Claimholder receives Post-Petition Interest and/or adequate protection payments in an Insolvency or
Liquidation Proceeding (“Junior Lien Adequate Protection Payments”) and the Senior Lien Claimholders do not
receive payment in full in cash of all Senior Lien Obligations upon the effectiveness of the plan of reorganization for, or conclusion
of, that Insolvency or Liquidation Proceeding, then each Junior Lien Claimholder shall pay over to the Senior Lien Claimholders
an amount (the “Pay-Over Amount”) equal to the lesser of (i) the Junior Lien Adequate Protection Payments
received by such Junior Lien Claimholder and (ii) the amount of the short-fall (the “Short Fall”) in payment
in full in cash of the Senior Lien Obligations; provided that to the extent any portion of the Short Fall represents payments
received by the Senior Lien Claimholders in the form of promissory notes, equity or other property equal in value to the cash paid
in respect of the Pay-Over Amount, the Senior Lien Claimholders shall, upon receipt of the Pay-Over Amount, transfer those promissory
notes, equity or other property, equal in value to the cash paid in respect of the Pay-Over Amount, to the applicable Junior Lien
Claimholders pro rata in exchange for the Pay-Over Amount. Notwithstanding anything herein to the contrary, the Senior Lien Claimholders
shall not be deemed to have consented to, and expressly retain their rights to object to, the grant of adequate protection in the
form of cash payments to the Junior Lien Claimholders made pursuant to this Section 6.3(b).

 

    25 

     

    

 

No Waiver. Subject to Section 6.7(b),
nothing contained herein shall prohibit or in any way limit any Senior Lien Representative or any other Senior Lien Claimholder
from objecting in any Insolvency or Liquidation Proceeding or otherwise to any action taken by any Junior Lien Representative or
any other Junior Lien Claimholder, including the seeking by any Junior Lien Representative or any other Junior Lien Claimholder
of adequate protection or the asserting by any Junior Lien Representative or any other Junior Lien Claimholder of any of its rights
and remedies under the Junior Lien Documents or otherwise.

 

Avoidance Issues. If any Senior Lien
Claimholder is required in any Insolvency or Liquidation Proceeding or otherwise to turn over or otherwise pay to the estate of
the Company any amount paid in respect of Senior Lien Obligations (a “Recovery”), then such Senior Lien Claimholder
shall be entitled to a reinstatement of its Senior Lien Obligations with respect to all such recovered amounts on the date of such
Recovery, and from and after the date of such reinstatement the Discharge of Senior Lien Obligations shall be deemed not to have
occurred for all purposes hereunder. If this Agreement shall have been terminated prior to such Recovery, this Agreement shall
be reinstated in full force and effect, and such prior termination shall not diminish, release, discharge, impair or otherwise
affect the obligations of the parties hereto from such date of reinstatement. This Section 6.5 shall survive termination of
this Agreement.

 

Reorganization Securities. If, in
any Insolvency or Liquidation Proceeding, debt obligations of the reorganized debtor secured by Liens upon any property of the
reorganized debtor are distributed pursuant to a plan of reorganization, arrangement, compromise or liquidation or similar dispositive
restructuring plan, both on account of Senior Lien Obligations and on account of Junior Lien Obligations, then, to the extent the
debt obligations distributed on account of the Senior Lien Obligations and on account of the Junior Lien Obligations are secured
by Liens upon the same property, the provisions of this Agreement will survive the distribution of such debt obligations pursuant
to such plan and will apply with like effect to the Liens securing such debt obligations.

 

6.7       Post-Petition
Interest.

 

(a)       None
of any Junior Lien Representative, any Junior Lien Collateral Agent or any other Junior Lien Claimholder shall oppose or seek to
challenge any claim by any Senior Lien Representative, any Senior Lien Collateral Agent or any other Senior Lien Claimholder for
allowance in any Insolvency or Liquidation Proceeding of Senior Lien Obligations consisting of Post-Petition Interest to the extent
of the value of the Lien of the Senior Lien Collateral Agents on behalf of the Senior Lien Claimholders on the Collateral or any
other Senior Lien Claimholder’s Lien on the Collateral, without regard to the existence of the Liens of the Junior Lien Collateral
Agents or the other Junior Lien Claimholders on the Collateral.

 

(b)       None
of any Senior Lien Representative, Senior Lien Collateral Agent or any other Senior Lien Claimholder shall oppose or seek to challenge
any claim by any Junior Lien Representative, Junior Lien Collateral Agent or any other Junior Lien Claimholder for allowance in
any Insolvency or Liquidation Proceeding of Junior Lien Obligations consisting of Post-Petition Interest to the extent of the value
of the Lien of the Junior Lien Collateral Agents, on behalf of the Junior Lien Claimholders, on the Collateral (after taking into
account the amount of the Senior Lien Obligations).

 

    26 

     

    

 

Waiver. Each Junior Lien Representative
and each Junior Lien Collateral Agent, for itself and on behalf of each other Junior Lien Claimholder represented by it, waives
any claim it may hereafter have against any Senior Lien Claimholder arising out of the election of any Senior Lien Claimholder
of the application of Section 1111(b)(2) of the Bankruptcy Code, and out of any cash collateral or financing arrangement or
out of any grant of a security interest in connection with the Collateral in any Insolvency or Liquidation Proceeding so long as
such actions are not in express contravention of the terms of this Agreement.

 

Separate Grants of Security and Separate
Classification. Each Junior Lien Representative and each Junior Lien Collateral Agent, for itself and on behalf of each other
Junior Lien Claimholder represented by it, and each Senior Lien Representative and each Senior Lien Collateral Agent, for itself
and on behalf of each other Senior Lien Claimholder represented by it, acknowledges and agrees that:

 

(a)       the
grants of Liens pursuant to the Senior Lien Collateral Documents and the Junior Lien Collateral Documents constitute two separate
and distinct grants of Liens; and

 

(b)       because
of, among other things, their differing rights in the Collateral, the Junior Lien Obligations are fundamentally different from
the Senior Lien Obligations and must be separately classified in any plan of reorganization proposed or adopted in an Insolvency
or Liquidation Proceeding.

 

To further effectuate the intent of the
parties as provided in the immediately preceding sentence, if it is held that the claims of the Senior Lien Claimholders and the
Junior Lien Claimholders in respect of the Collateral constitute only one secured claim (rather than separate classes of senior
and junior secured claims), then each of the parties hereto hereby acknowledges and agrees that all distributions shall be made
as if there were separate classes of senior and junior secured claims against the Company in respect of the Collateral (with the
effect being that, to the extent that the aggregate value of the Collateral is sufficient (for this purpose ignoring all claims
held by the Junior Lien Claimholders), the Senior Lien Claimholders shall be entitled to receive, in addition to amounts distributed
to them in respect of principal, pre-petition interest and other claims, all amounts owing (or that would be owing if there were
such separate classes of senior and junior secured claims) in respect of Post-Petition Interest (including any additional interest
payable pursuant to the Senior Lien Documents, arising from or related to a default, which is disallowed as a claim in any Insolvency
or Liquidation Proceeding) before any distribution is made in respect of the claims held by the Junior Lien Claimholders with respect
to the Collateral, with each Junior Lien Representative and each Junior Lien Collateral Agent, for itself and on behalf of each
other Junior Lien Claimholder represented by it, hereby acknowledging and agreeing to turn over to the Senior Lien Collateral Agent,
for itself and on behalf of each other Senior Lien Claimholder, Collateral or proceeds of Collateral otherwise received or receivable
by them to the extent necessary to effectuate the intent of this sentence, even if such turnover has the effect of reducing the
claim or recovery of the Junior Lien Claimholders).

 

Effectiveness in Insolvency or Liquidation
Proceedings. The Parties acknowledge that this Agreement is a “subordination agreement” under section 510(a)
of the Bankruptcy Code, which will be effective before, during and after the commencement of an Insolvency or Liquidation Proceeding.
All references in this Agreement to the Company will include such Person as a debtor-in-possession and any receiver or trustee
for such Person in an Insolvency or Liquidation Proceeding.

 

Section 7.Reliance;
Waivers.

 

Reliance. Other than any reliance
on the terms of this Agreement, each Senior Lien Representative and each Senior Lien Collateral Agent, on behalf of itself and
each other Senior Lien Claimholder represented by it, acknowledges that it and such Senior Lien Claimholders have, independently
and without reliance on any Junior Lien Representative, any Junior Lien Collateral Agent or any other Junior Lien Claimholder,
and based on documents and information deemed by them appropriate, made their own credit analysis and decision to enter into each
of the Senior Lien Documents and be bound by the terms of this Agreement and they will continue to make their own credit decision
in taking or not taking any action under the Senior Lien Documents or this Agreement. Each Junior Lien Representative and each
Junior Lien Collateral Agent, on behalf of itself and each other Junior Lien Claimholder represented by it, acknowledges that it
and such Junior Lien Claimholders have, independently and without reliance on any Senior Lien Representative, any Senior Lien Collateral
Agent or any other Senior Lien Claimholder, and based on documents and information deemed by them appropriate, made their own credit
analysis and decision to enter into each of the Junior Lien Documents and be bound by the terms of this Agreement and they will
continue to make their own credit decision in taking or not taking any action under the Junior Lien Documents or this Agreement.

by it, acknowledges and agrees that no Junior Lien Representative or other Junior Lien Claimholder has made any express or implied
representation or warranty, including with respect to the execution, validity, legality, completeness, collectability or enforceability
of any of the Junior Lien Documents, the ownership of any Collateral or the perfection or priority of any Liens thereon. Except

of credit under the Junior Lien Documents in accordance with law and as they may otherwise, in their sole discretion, deem appropriate.

agreements with the Company (including the Senior Lien Documents and the Junior Lien Documents), regardless of any knowledge thereof
which they may have or be charged with.

(a)       No
right of the Senior Lien Claimholders, the Senior Lien Representatives, the Senior Lien Collateral Agents or any of them to enforce

Obligations Unconditional. All rights,
interests, agreements and obligations of the Senior Lien Representatives, the Senior Lien Collateral Agents and the other Senior

Section 8.Miscellaneous.

 

Integration/Conflicts. This Agreement,
the Senior Lien Documents and the Junior Lien Documents represent the entire agreement by and among the Company, the Senior Lien
Claimholders and the Junior Lien Claimholders with respect to the subject matter hereof and thereof, and supersede any and all
previous agreements and understandings, oral or written, relating to the subject matter hereof and thereof. There are no promises,
undertakings, representations or warranties by the Senior Lien Claimholders or the Junior Lien Claimholders relative to the subject
matter hereof and thereof not expressly set forth or referred to herein or therein. In the event of any conflict between the provisions
of this Agreement and the provisions of the Senior Lien Documents or the Junior Lien Documents, the provisions of this Agreement
shall govern and control.

 

Effectiveness; Continuing Nature of this
Agreement; Severability. This Agreement shall become effective when executed and delivered by the parties hereto. This is a
continuing agreement of lien subordination and the Senior Lien Claimholders may continue, at any time and without notice to any
Junior Lien Representative or any other Junior Lien Claimholder, to extend credit and other financial accommodations and lend monies
to or for the benefit of the Company or Centrus constituting Senior Lien Obligations in reliance hereon. Each Junior Lien Representative
and each Junior Lien Collateral Agent, on behalf of itself and each other Junior Lien Claimholder represented by it, hereby waives
any right it may have under applicable law to revoke this Agreement or any of the provisions of this Agreement. The terms of this
Agreement shall survive, and shall continue in full force and effect, in any Insolvency or Liquidation Proceeding. Any provision
of this Agreement that 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. The
parties hereto shall endeavor in good-faith negotiations to replace any invalid, illegal or unenforceable provisions with valid
provisions the economic effect of which comes as close as possible to those of the invalid, illegal or unenforceable provisions.
All references to the Company shall include the Company as debtor and debtor-in-possession and any receiver, trustee or similar
person acting for the Company (as the case may be) in any Insolvency or Liquidation Proceeding. This Agreement shall terminate
and be of no further force and effect:

 

    30 

     

    

 

(a)       with
respect to any Senior Lien Representative and any Senior Lien Collateral Agent, the Senior Lien Claimholders represented by them
and their Senior Lien Obligations, on the date on which the Senior Lien Obligations of such Senior Lien Claimholders are Discharged,
subject to the rights of such Senior Lien Claimholders under Sections 5.8 and 6.5; and

 

(b)       with
respect to any Junior Lien Representative and any Junior Lien Collateral Agent, the Junior Lien Claimholders represented by them
and their Junior Lien Obligations, on the date on which the Junior Lien Obligations of such Junior Lien Claimholders are Discharged
subject to the rights of such Junior Lien Claimholders under Sections 5.8 and 6.5;

 

provided, however, that in each case, such termination
shall not relieve any such party of its obligations incurred hereunder prior to the date of such termination.

 

8.3       Amendments;
Waivers.

 

(a)       No
amendment, modification or waiver of any of the provisions of this Agreement shall be deemed to be made unless the same shall
be in writing signed on behalf of each party hereto or its authorized agent and each waiver, if any, shall be a waiver only with
respect to the specific instance involved and shall in no way impair the rights of the parties making such waiver or the obligations
of the other parties to such party in any other respect or at any other time. Notwithstanding the foregoing, the Company shall
not have any right to consent to or approve any amendment, modification or waiver of any provision of this Agreement except to
the extent their rights are directly and adversely affected; provided that upon execution and delivery of an acknowledgement substantially
in the form of Exhibit D attached hereto (the “Supplemental Acknowledgement”) by an Additional Grantor, such
Additional Grantor shall have acknowledged and agreed to the terms in this Agreement in the same manner as the Company on the
date hereof.

 

(b)       Notwithstanding
the foregoing, without the consent of any Senior Lien Claimholder or Junior Lien Claimholder, any Representative and Collateral
Agent may become a party hereto by execution and delivery of a Joinder Agreement in accordance with Section 8.7 of
this Agreement and upon such execution and delivery, such Representative and Collateral Agent and the Additional Senior Lien Claimholders
and Additional Senior Lien Obligations or Additional Junior Lien Claimholders and Additional Junior Lien Obligations of the Series
for which such Representative and Collateral Agent is acting shall be subject to the terms hereof.

 

(c)       Notwithstanding
the foregoing, without the consent of any other Representative, Collateral Agent or Senior Lien Claimholder, the Senior Lien Representative
may effect amendments and modifications to this Agreement to the extent necessary to reflect any incurrence of any Additional Senior
Lien Obligations or Additional Junior Lien Obligations in compliance with this Agreement.

 

Information Concerning Financial Condition
of the Company and its Subsidiaries. The Senior Lien Representatives, the Senior Lien Collateral Agents and the Senior Lien
Claimholders, on the one hand, and the holders of the Junior Lien Obligations, on the other hand, shall each be responsible for
keeping themselves informed of (a) the financial condition of the Company and its Subsidiaries and any endorsers or guarantors
of the Senior Lien Obligations or the Junior Lien Obligations and (b) all other circumstances bearing upon the risk of nonpayment
of the Senior Lien Obligations or the Junior Lien Obligations. The Senior Lien Representatives, the Senior Lien Collateral Agents
and the other Senior Lien Claimholders, on the one hand, and the Junior Lien Representatives, the Junior Lien Collateral Agents
and any other Junior Lien Claimholder, on the other hand, shall have no duty to advise of information known to it or them regarding
such condition or any such circumstances or otherwise. In the event any Claimholder, in its sole discretion, undertakes at any
time or from time to time to provide any such information to any other Claimholder, it shall be under no obligation:

 

(a)       to
make, and such Claimholder shall not make, any express or implied representation or warranty, including with respect to the accuracy,
completeness, truthfulness or validity of any such information so provided;

 

    31

Subrogation. With respect to the
value of any payments or distributions in cash, property or other assets that any of the Junior Lien Representatives, the Junior
Lien Collateral Agents or the other Junior Lien Claimholders pays over to any of the Senior Lien Representatives, the Senior Lien
Collateral Agents or the other Senior Lien Claimholders under the terms of this Agreement, such Junior Lien Claimholders, Junior
Lien Representatives and Junior Lien Collateral Agents shall be subrogated to the rights of such Senior Lien Representatives, Senior
Lien Collateral Agents and Senior Lien Claimholders; provided that each Junior Lien Representative and each Junior Lien Collateral
Agent, on behalf of itself and each other Junior Lien Claimholder represented by it, hereby agrees not to assert or enforce any
such rights of subrogation it may acquire as a result of any payment hereunder until the Discharge of Senior Lien Obligations has
occurred. The Company acknowledges and agrees that the value of any payments or distributions in cash, property or other assets
received by any Junior Lien Representative, Junior Lien Collateral Agent or other Junior Lien Claimholder that are paid over to
any Senior Lien Representative, Senior Lien Collateral Agent or other Senior Lien Claimholder pursuant to this Agreement shall
not reduce any of the Junior Lien Obligations.

 

Application of Payments. All payments
received by any Senior Lien Representative, Senior Lien Collateral Agent or other Senior Lien Claimholder may be applied, reversed
and reapplied, in whole or in part, to such part of the Senior Lien Obligations provided for in the Senior Lien Documents (subject
to the Senior Lien Intercreditor Agreement and any other Intercreditor Agreement, if then in effect). Each Junior Lien Representative
and each Junior Lien Collateral Agent, on behalf of itself and each other Junior Lien Claimholder represented by it, agrees to
any extension or postponement of the time of payment of the Senior Lien Obligations or any part thereof and to any other indulgence
with respect thereto, to any substitution, exchange or release of any Lien which may at any time secure any part of the Senior
Lien Obligations and to the addition or release of any other Person primarily or secondarily liable therefor.

 

8.7       Additional
Senior Lien Claims and Additional Junior Debt.

 

(a)       To
the extent, but only to the extent, permitted by the provisions of the Senior Lien Documents and the Junior Lien Documents and
Section 5.5, the Company may incur or issue or guarantee any one or more Senior Lien Claims that the Company designates
as Additional Senior Lien Claims and one or more series or classes of Indebtedness that Refinances any Initial Junior Lien Debt
and that the Company designates as Additional Junior Lien Debt.

 

Any such series or class of Additional Senior
Lien Claims may be secured by a first-priority, senior Lien on the Collateral, in each case under and pursuant to the Senior Lien
Collateral Documents for such Series of Additional Senior Lien Claims. The Senior Lien Representative and Senior Lien Collateral
Agent in respect of any Additional Senior Lien Claims may elect to become a party hereto by satisfying the conditions set forth
in clauses (1) through (3) of Section 8.7(b).

 

Any such Additional Junior Lien Debt may
be secured by a junior-priority, subordinated Lien on the Collateral, in each case under and pursuant to the relevant Junior Lien
Collateral Documents for such Series of Additional Junior Lien Debt, if and subject to the condition, the Additional Junior Lien
Representative and Additional Junior Lien Collateral Agent of any such Additional Junior Lien Debt each becomes a party to this
Agreement by satisfying the conditions set forth in clauses (1) through (3) of Section 8.7(b). Upon any Additional
Junior Lien Representative and Additional Junior Lien Collateral Agent so becoming a party hereto, all Additional Junior Lien Obligations
of such Series shall also be entitled to be so secured by a subordinated Lien on the Collateral in accordance with the terms hereof
and thereof.

 

(b)       In

as may be reasonably approved by the Senior Lien Representative and such Representative and such Collateral Agent) pursuant to
which such Additional Representative becomes a Representative hereunder, such Additional Collateral Agent becomes a Collateral
Agent hereunder and the related Senior Lien Claimholders or Junior Lien Claimholders, as applicable, become subject hereto and
bound hereby;

 

(2)       the
Company shall have delivered a Designation to each other then-existing Collateral Agent substantially in the form of Exhibit C

Additional Senior Lien Claims, or the Indebtedness to be designated as Additional Junior Lien Debt, as applicable, and the initial
aggregate principal amount of such Indebtedness, (B) specify the name and address of the applicable Additional Representative
and Additional Collateral Agent and (C) certify that such Additional Senior Lien Claim or Additional Junior Lien Debt is permitted
to be incurred, secured and guaranteed by each of the Senior Lien Documents and Junior Lien Documents, respectively, and that the
conditions set forth in this Section 8.7 are satisfied with respect to such Additional Senior Lien Claim or Additional
Junior Lien Debt, as applicable; and

 

(3)       the
Company shall have delivered to each other Collateral Agent true and complete copies of each of the Senior Lien Documents or Junior
Lien Documents, as applicable, relating to such Additional Senior Lien Claims or Additional Junior Lien Debt, as applicable.

provide that each of the applicable Claimholders with respect to such Additional Obligations will be subject to and bound by the
provisions of this Agreement.

Section
1.02 [Reserved].

 

Section
1.03 Limitation on Guarantor’s Liability.

 

The Guarantor and by its acceptance hereof
each Holder hereby confirms that it is the intention of all such parties that the guarantee by the Guarantor pursuant to its Guarantee
not constitute a fraudulent transfer or conveyance for purposes of the Bankruptcy Code, the Uniform Fraudulent Conveyance Act,
the Uniform Fraudulent Transfer Act or any similar Federal or state law. To effectuate the foregoing intention, the Trustee, the
Holders and the Guarantor hereby irrevocably agree that the Guaranteed Obligations shall be limited to the maximum amount as will,
after giving effect to all other contingent and fixed liabilities of the Guarantor, result in the Guaranteed Obligations not constituting
a fraudulent conveyance or fraudulent transfer under Federal or state law or render the Guarantor insolvent.

 

Section
1.04 Rights Under the Guarantee.

payment by the Guarantor pursuant to the provisions hereof shall entitle the Guarantor to any payment out of any Collateral or
give rise to any claim of the Guarantor against the Trustee or any Holder.

Guarantor waives notice of the issuance, sale and purchase of the Notes and notice from the Trustee or the Holders from time to

Guarantor shall pay all reasonable costs and expenses (including all reasonable attorneys’ fees), that may be incurred by
the Trustee in enforcing or attempting to enforce the Guarantee.

 

Section
1.05 Guaranty of Payment Not Collection.

 

The Guaranteed Obligations of the Guarantor
hereunder shall constitute a guaranty of payment when due and not a guaranty of collection. The Guarantor agrees that its obligations
hereunder are independent of the obligations of the Issuer, and that a separate action may be brought against it, whether such
action is brought against the Issuer or whether the Issuer is joined in such action. The Guarantor agrees that its liability hereunder
shall be immediate and shall not be contingent upon the exercise or enforcement by the Trustee or the Holders of whatever remedies
they may have against the Issuer, or the enforcement of any lien or realization

 

    	 	3	 

     

    

upon any security the Collateral Agent or the Trustee may at
any time possess. The Guarantor agrees that any release that may be given by the Collateral Agent, Trustee or the Holders to the
Issuer shall not release the Guarantor.

 

Section
1.06 No Subrogation.

 

Notwithstanding any payment or payments

Holder against the Issuer or any collateral security or guarantee or right of offset held by the Trustee or any Holder for the
payment of the Guaranteed Obligations, nor shall the Guarantor seek or be entitled to seek any contribution or reimbursement from
the Issuer in respect of payments made by the Guarantor hereunder, until all amounts owing to the Trustee and the Holders by the
Issuer under the Notes and the Issuer’s Obligations thereunder are paid in full. If any amount shall be paid to the Guarantor
on account of such subrogation rights at any time when the Notes and the Issuer’s Obligations thereunder and hereunder shall
not have been paid in full, such amount shall be held by the Guarantor in trust for the Trustee and the Holders, segregated from
other funds of the Guarantor, and shall, forthwith upon receipt by the Guarantor, be turned over to the Trustee in the exact form
received by the Guarantor (duly indorsed by the Guarantor to the Trustee, if required), to be applied against the Guaranteed Obligations.

 

Section
1.07 Release of the Guarantor

 

The Guarantor will be automatically and
unconditionally released and discharged from all of its Guaranteed Obligations in connection with a Legal Defeasance or Covenant
Defeasance of the Indenture in accordance with Article 8 of the Indenture or upon satisfaction and discharge of the Indenture in
accordance with Article 12 of the Indenture.

 

Section
1.08 Ranking.

 

The Guaranted Obligations shall in all respects
rank pari passu in right of payment with all existing and future unsubordinated Indebtedness of the Guarantor, and will be senior

Debt.

obligations in this Section 2.02, the Trustee shall have a Lien prior to the Notes on all money or property held or collected

and the compensation for the services are intended to constitute expenses of administration under any Bankruptcy Code.

(3)                
subject to their rights under clause (a)(1) above will not object to the forbearance by any Senior Lien Representative,
any Senior Lien Collateral Agent or any Limited Secured Acquisition Claimholder from bringing or pursuing any foreclosure proceeding
or action or any other exercise of any rights or remedies relating to the Collateral, in each case so long as any proceeds received
by any Senior Lien Representative in excess of those necessary to achieve a Discharge of Limited Secured Acquisition Obligations
are distributed in accordance with Section 5.1 hereof and applicable law.

 

(b)                
(b) Until the Discharge of Limited Secured Acquisition Obligations has occurred, whether or not any Insolvency or Liquidation
Proceeding has been commenced by or against the Company, subject to Section 4.1(a)(1), the Senior Lien Representatives,
the Senior Lien Collateral Agents and the Limited Secured Acquisition Claimholders shall have the exclusive right to (i) commence
and maintain a Collateral Enforcement Action or otherwise enforce rights, exercise remedies (including set-off, recoupment and
the right to credit bid their debt, except that Junior Lien Representatives shall have the credit bid rights set forth in Section 4.1(c)(6)),
and (ii) subject to Section 5.3, make determinations regarding the release, disposition, or restrictions with
respect to the Collateral without any consultation with or the consent of any Junior Lien Representative, any Junior Lien Collateral
Agent or any other Junior

Lien Claimholder; provided that, in each case,
any proceeds received by any Senior Lien Representative in excess of those necessary to achieve a Discharge of Limited Secured
Acquisition Obligations are distributed in accordance with Section 5.1 hereof and applicable law. In commencing or
maintaining any Collateral Enforcement Action or otherwise exercising rights and remedies with respect to the Collateral, the Senior
Lien Representatives, Senior Lien Collateral Agents and the Limited Secured Acquisition Claimholders may enforce the provisions
of the Senior Lien Documents and exercise remedies thereunder, all in such order and in such manner as they may determine in the
exercise of their sole discretion in compliance with any applicable law and without consultation with any Junior Lien Representative,
any Junior Lien Collateral Agent or any other Junior Lien Claimholder and regardless of whether any such exercise is adverse to
the interest of any Junior Lien Claimholder. Such exercise and enforcement shall include the rights of an agent appointed by them
to sell or otherwise dispose of Collateral upon foreclosure, to incur expenses in connection with such sale or disposition, and
to exercise all the rights and remedies of a secured creditor under the UCC and under Bankruptcy Law of any applicable jurisdiction.

 

(c)                
Notwithstanding the foregoing, any Junior Lien Representative, any Junior Lien Collateral Agent, in accordance with any
relevant Junior Lien Security Document, and any other Junior Lien Claimholder may:

 

(1)                
file a claim or statement of interest with respect to the Junior Lien Obligations; provided that an Insolvency or
Liquidation Proceeding has been commenced by or against the Company;

 

(2)                
take any action not adverse to the priority status of the Liens on the Collateral securing the Limited Secured Acquisition
Obligations, or the rights of any Senior Lien Representative, any Senior Lien Collateral Agent or the Limited Secured Acquisition
Claimholders to exercise remedies in respect thereof, in order to create, perfect, preserve or protect its Lien on the Collateral;

 

(3)                
file any necessary responsive or defensive pleadings in opposition to any motion, claim, adversary proceeding or other pleading
made by any person objecting to or otherwise seeking the disallowance of the claims of the Junior Lien Claimholders, including
any claims secured by the Collateral, if any, in each case in accordance with the terms of this Agreement;

 

(4)                
vote on any plan of reorganization, arrangement, compromise or liquidation, file any proof of claim, make other filings
and make any arguments and motions that are, in each case, in accordance with the terms of this Agreement, with respect to the
Junior Lien Obligations and the Collateral; provided that no filing of any claim or vote, or pleading related to such claim
or vote, to accept or reject a disclosure statement, plan of reorganization, arrangement, compromise or liquidation, or any other
document, agreement or proposal similar to the foregoing by any Junior Lien Representative, any Junior Lien Collateral Agent or
any other Junior Lien Claimholder, may be inconsistent with the provisions of this Agreement;

 

(5)                
exercise any of its rights or remedies with respect to the Collateral after the termination of the Standstill Period to
the extent permitted by Section 4.1(a)(1); and

 

(6)                
bid for or purchase Collateral at any public, private or judicial foreclosure upon such Collateral initiated by any Senior
Lien Representative, any Senior Lien Collateral Agent or any other Limited Secured Acquisition Claimholder, or any sale of Collateral
during an Insolvency or Liquidation Proceeding; provided that such bid may not include a “credit bid” in respect
of any Junior Lien Obligations unless the cash proceeds of such bid are otherwise sufficient to cause the Discharge of Limited
Secured Acquisition Obligations.

 

Each Junior Lien Representative and each
Junior Lien Collateral Agent, on behalf of itself and each other Junior Lien Claimholder represented by it, agrees that it will
not take or receive any Collateral or any proceeds of Collateral in connection with the exercise of any right or remedy (including
set-off and recoupment) with respect to

 

    	 	13	 

     

    

any Collateral in its capacity as a creditor, unless and until
the Discharge of Limited Secured Acquisition Obligations has occurred, except in connection with any foreclosure that is expressly
permitted by Section 4.1(a)(1) to pursue after the expiration of the Standstill Period to the extent such Junior Lien
Representative or such Junior Lien Collateral Agent and Junior Lien Claimholders represented by it are permitted to retain the
proceeds thereof in accordance with Section 5.2 of this Agreement. Without limiting the generality of the foregoing,
unless and until the Discharge of Limited Secured Acquisition Obligations has occurred, except as expressly provided in Sections 4.1(a),
6.3(b) and this Section 4.1(c), the sole right of the Junior Lien Representatives, the Junior Lien Collateral Agents
and the other Junior Lien Claimholders with respect to the Collateral is to hold a Lien on the Collateral pursuant to the Junior
Lien Collateral Documents for the period and to the extent granted therein and to receive a share of the proceeds thereof, if any,
after the Discharge of Limited Secured Acquisition Obligations has occurred.

 

(d)                
Subject to Sections 4.1(a) and (c) and Section 6.3(b):

 

(1)                
each Junior Lien Representative and each Junior Lien Collateral Agent, for itself and on behalf of each other Junior Lien
Claimholder represented by it, agrees that such Junior Lien Representative or such Junior Lien Collateral Agent and such Junior
Lien Claimholders represented by it will not take any action that would hinder any exercise of remedies under the Senior Lien Documents
or that is otherwise prohibited hereunder, including any sale, lease, exchange, transfer or other disposition of the Collateral,
whether by foreclosure or otherwise;

 

(2)                
each Junior Lien Representative and each Junior Lien Collateral Agent, for itself and on behalf of each other Junior Lien
Claimholder represented by it, hereby waives any and all rights such Junior Lien Representative or such Junior Lien Collateral
Agent and such Junior Lien Claimholders represented by it may have as a junior lien creditor or otherwise to object to the manner
in which any Senior Lien Representative, any Senior Lien Collateral Agent or any other Limited Secured Acquisition Claimholder
seeks to enforce or collect the Limited Secured Acquisition Obligations or Liens securing the Limited Secured Acquisition Obligations
granted in any of the Collateral undertaken in accordance with this Agreement, regardless of whether any action or failure to act
by or on behalf of any Senior Lien Representative, any Senior Lien Collateral Agent or any other Limited Secured Acquisition Claimholder
is adverse to the interest of any Junior Lien Claimholder; and

 

(3)                
each Junior Lien Representative and each Junior Lien Collateral Agent, for itself and on behalf of each other Junior Lien
Claimholder represented by it, hereby acknowledges and agrees that no covenant, agreement or restriction contained in any Junior
Lien Documents (other than this Agreement) shall be deemed to restrict in any way the rights and remedies of any Senior Lien Representative,
any Senior Lien Collateral Agent or any other Limited Secured Acquisition Claimholder with respect to the Collateral as set forth
in this Agreement and the Senior Lien Documents.

 

(e)                
The Junior Lien Representatives, the Junior Lien Collateral Agents and the other Junior Lien Claimholders may exercise rights
and remedies as unsecured creditors (or as secured creditors with respect any Junior Lien Collateral that does not constitute Collateral)
against the Company that has guaranteed or granted Liens to secure the Junior Lien Obligations in accordance with the terms of
the Junior Lien Documents and applicable law (other than initiating or joining in an involuntary case or proceeding under any Insolvency
or Liquidation Proceeding with respect to the Company); provided that in the event that any Junior Lien Claimholder becomes
a judgment Lien creditor in respect of Collateral as a result of its enforcement of its rights as an unsecured creditor with respect
to the Junior Lien Obligations, such judgment Lien shall be subject to the terms of this Agreement for all purposes (including
in relation to the Limited Secured Acquisition Obligations) in the same manner as the other Liens securing the Junior Lien Obligations
are subject to this Agreement.

 

(f)                 
Except as specifically set forth in Sections 4.1(a) and (d), nothing in this Agreement shall prohibit
the receipt by any Junior Lien Representative, any Junior Lien Collateral Agent or any other Junior Lien Claimholder of the required
payments of interest, principal and other amounts owed in respect of the

 

    	 	14	 

     

    

Junior Lien Obligations so long as such receipt is
not the direct or indirect result of the exercise by any Junior Lien Representative, any Junior Lien Collateral Agent or any other
Junior Lien Claimholder of rights or remedies as a secured creditor (including set-off and recoupment) with respect to the Collateral
or enforcement in contravention of this Agreement of any Lien on the Collateral held by any of them or as a result of any other
violation by any Junior Lien Claimholder of the express terms of this Agreement. Nothing in this Agreement impairs or otherwise
adversely affects any rights or remedies any Senior Lien Representative, any Senior Lien Collateral Agent or other Limited Secured
Acquisition Claimholder may have with respect to the Senior Lien Collateral.

 

(g)                
Nothing in this Agreement impairs or otherwise adversely affects any rights or remedies any Junior Lien Representative,
any Junior Lien Collateral Agent or any other Junior Lien Claimholder may have with respect to any Junior Lien Collateral that
does not constitute Collateral.

 

4.2               
Actions Upon Breach; Specific Performance. If any Junior Lien Claimholder, in contravention of the terms of this
Agreement, in any way takes, attempts to or threatens to take any action with respect to the Collateral (including any attempt
to realize upon or enforce any remedy with respect to this Agreement), or fails to take any action required by this Agreement,
this Agreement shall create an irrebutable presumption and admission by such Junior Lien Claimholder that relief against such Junior
Lien Claimholder by injunction, specific performance and/or other appropriate equitable relief is necessary to prevent irreparable
harm to the Limited Secured Acquisition Claimholders, it being understood and agreed by each Junior Lien Representative and each
Junior Lien Collateral Agent, on behalf of each Junior Lien Claimholder represented by it, that (i) the Limited Secured Acquisition
Claimholders’ damages from actions of any Junior Lien Claimholder may at that time be difficult to ascertain and may be irreparable
and (ii) each Junior Lien Claimholder waives any defense that either or both the Company and the Limited Secured Acquisition
Claimholders cannot demonstrate either or both damage and be made whole by the awarding of damages. Each of the Senior Lien Representatives
and Senior Lien Collateral Agents may demand specific performance of this Agreement. Each Junior Lien Representative and each Junior
Lien Collateral Agent, on behalf of itself and each other Junior Lien Claimholder represented by it, hereby irrevocably waives
any defense based on the adequacy of a remedy at law and any other defense which might be asserted to bar the remedy of specific
performance in any action which may be brought by any Senior Lien Representative, any Senior Lien Collateral Agent or any other
Limited Secured Acquisition Claimholder. No provision of this Agreement shall constitute or be deemed to constitute a waiver by
any Senior Lien Representative or any Senior Lien Collateral Agent on behalf of itself and each other Limited Secured Acquisition
Claimholder represented by it, of any right to seek damages from any Person in connection with any breach or alleged breach of
this Agreement.

of the Collateral, in each case prior to the Discharge of Limited Secured Acquisition Obligations, such Senior Lien Collateral
Agent, for itself or on behalf of any of the Limited Secured Acquisition Claimholders represented by it, releases any of its Liens
on any part of the Collateral, then the Liens, if any, of each Junior Lien Collateral Agent, for itself or for the benefit of the
Junior Lien Claimholders, on such Collateral, shall be automatically, unconditionally and simultaneously released. Each Junior
Lien Representative and each Junior Lien Collateral Agent, for itself or on behalf of any Junior Lien Claimholder represented by
it, shall, within a reasonable time following such request, execute and deliver to the Senior Lien Representatives, Senior Lien

Until the Discharge of Limited Secured Acquisition Obligations occurs, each Junior Lien Representative and each Junior Lien
Collateral Agent, for itself and on behalf of each other Junior Lien Claimholder represented by it, hereby irrevocably constitutes

such Liens are later reinstated or (ii) obtains any new Liens from the Company, then each Junior Lien Collateral Agent, for
itself and for the Junior Lien Claimholders represented by it, shall be granted a Lien on any such Collateral (except to the extent
such Lien represents a Junior Lien Declined Lien with respect to the Junior Lien Debt represented by such Junior Lien Collateral
Agent), subject to the lien subordination provisions of this Agreement, and each Junior Lien Representative, for itself and for
the Junior Lien Claimholders represented by it, shall be granted an additional lien.

(or any deed in lieu of condemnation) affecting the Collateral. Subject to the rights of the Company under the Senior Lien Documents,
all proceeds of any such policy and any such award (or any payments with respect to a deed in lieu of condemnation) if in respect
of the Collateral shall be applied in the order of priority set forth in Section 5.1. Until the Discharge of Limited Secured
Acquisition Obligations has occurred, if any Junior Lien Representative, any Junior Lien Collateral Agent or any other Junior Lien
Claimholder shall, at any time, receive any proceeds of any such insurance policy or any such award or payment in contravention
of this Agreement, then it shall segregate and hold in trust and forthwith pay such proceeds over to the Designated Senior Lien
Collateral Agent in accordance with the terms of Section 5.2.

of this Agreement; provided that any such amendment, supplement or modification or Refinancing is not inconsistent with
the terms of this Agreement and, in the case of a Refinancing, the holders of such Refinancing debt or their agent bind themselves
in a writing addressed to each Junior Lien Collateral Agent to the terms of this Agreement.

5.7               
Gratuitous Bailee/Agent for Perfection; Rights of Initial Senior Collateral Agent and Initial Senior Lien Representative.

 

(a)                
Each Senior Lien Collateral Agent agrees to hold that part of the Collateral that is in its possession or control (or in
the possession or control of its agents or bailees) to the extent that possession or control thereof is taken to perfect a Lien
thereon under the UCC (such Collateral being the “Pledged Collateral”) as collateral agent for the Limited Secured
Acquisition Claimholders and gratuitous bailee for the Junior Lien Collateral Agents (such bailment being intended, among other
things, to satisfy the requirements of Sections 8-106(d)(3), 8-301(a)(2) and 9-313(c) of the UCC) and any assignee thereof
solely for the purpose of perfecting the security interest granted under the Senior Lien Documents and the Junior Lien Documents,
respectively, subject to the terms and conditions of this Section 5.7. Solely with respect to any deposit accounts
under the control (within the meaning of Section 9-104 of the UCC) of any Senior Lien Collateral Agent, such Senior Lien Collateral
Agent hereby agrees to also hold control over such deposit accounts as gratuitous agent for the Junior Lien Collateral Agents,
subject to the terms and conditions of this Section 5.7.

 

(b)                
No Senior Lien Collateral Agent shall have any obligation whatsoever to the Junior Lien Representatives, the Junior Lien
Collateral Agents or the Junior Lien Claimholders to ensure that the Pledged Collateral is genuine or owned by the Company, to
perfect the security interests of the Junior Lien Collateral Agents or other Junior Lien Claimholders or to preserve rights or
benefits of any Person except as expressly set forth in this Section 5.7. The duties or responsibilities of any Senior
Lien Collateral Agent under this Section 5.7 shall be limited solely to holding the Pledged Collateral as gratuitous
bailee (and with respect to deposit accounts, agent) in accordance with this Section 5.7 and delivering the Pledged
Collateral upon a Discharge of Limited Secured Acquisition Obligations as provided in paragraph (d) below.

 

(c)                
No Senior Lien Collateral Agent or any other Limited Secured Acquisition Claimholder shall have by reason of the Senior
Lien Collateral Documents, the Junior Lien Collateral Documents, this Agreement or any other document, a fiduciary relationship
in respect of any Junior Lien Representative or

 

    	 	18	 

     

    

any other Junior Lien Claimholder and the Junior Lien
Representatives, the Junior Lien Collateral Agents and the Junior Lien Claimholders hereby waive and release the Senior Lien Collateral
Agents and the other Limited Secured Acquisition Claimholders from all claims and liabilities arising pursuant to any Senior Lien
Collateral Agent’s role under this Section 5.7 as gratuitous bailee and gratuitous agent with respect to the
Pledged Collateral. It is understood and agreed that the interests of the Senior Lien Collateral Agents and the other Limited Secured
Acquisition Claimholders, on the one hand, and the Junior Lien Representatives, the Junior Lien Collateral Agents and the other
Junior Lien Claimholders on the other hand, may differ and the Senior Lien Collateral Agents and the other Limited Secured Acquisition
Claimholders shall be fully entitled to act in their own interest without taking into account the interests of the Junior Lien
Representatives, the Junior Lien Collateral Agents or other Junior Lien Claimholders.

 

(d)                
Upon the Discharge of Limited Secured Acquisition Obligations, each Senior Lien Collateral Agent shall deliver the remaining
Pledged Collateral in its possession (if any) together with any necessary endorsements (which endorsement shall be without recourse
and without any representation or warranty), (x) unless a Discharge of Junior Lien Obligations has not already occurred, to
the Junior Lien Collateral Agent and (y) if a Discharge of Junior Lien Obligations has already occurred, to the Company or
to whomever may be lawfully entitled to receive the same. Following the Discharge of Limited Secured Acquisition Obligations, each
Senior Lien Collateral Agent further agrees to take all other action required or requested by any Junior Lien Collateral Agent
at the expense of the Company in connection with the Junior Lien Collateral Agents obtaining a first-priority security interest
in the Collateral. After the Discharge of Limited Secured Acquisition Obligations has occurred, upon the Discharge of Junior Lien
Obligations, each Junior Lien Collateral Agent shall deliver the remaining Pledged Collateral in its possession (if any) together
with any necessary endorsements (which endorsement shall be without recourse and without any representation or warranty, to the
Company or to whomever may be lawfully entitled to receive the same.

 

(e)                
Upon execution of this Agreement, each Junior Lien Representative and Junior Lien Collateral Agent shall, promptly following
such requirements or requests, (x) enter into such documents and agreements as the Company or the Initial Senior Lien Representative
and/or the Initial Senior Lien Collateral Agent or Initial Senior Lien Representative shall reasonably request in order to provide
to the Initial Senior Lien Collateral Agent and Initial Senior Lien Representative the rights contemplated hereby, in each case
consistent in all material respects with the terms of this Agreement and (y) deliver to such Initial Senior Lien Collateral
Agent any Pledged Collateral held by it together with any necessary endorsements (or otherwise allow such Initial Senior Lien Collateral
Agent to obtain control of such Pledged Collateral), provided that the Junior Lien Representative or Junior Lien Collateral
Agent shall not be required to take any action if such actions would violate applicable law or court order.

 

5.8               
When Discharge of Obligations Deemed to Not Have Occurred. If, at any time after the Discharge of Limited Secured
Acquisition Obligations has occurred or contemporaneously therewith, the Company enters into any Refinancing of any Senior Lien
Documents evidencing a Limited Secured Acquisition Obligation, then such Discharge of Limited Secured Acquisition Obligations shall
automatically be deemed not to have occurred for all purposes of this Agreement (other than with respect to any actions taken as
a result of the occurrence of such first Discharge of Limited Secured Acquisition Obligations), and, from and after the date on
which the Additional Senior Lien Representative and Additional Senior Lien Collateral Agent in respect of such Refinancing each
becomes a party to this Agreement in accordance with Section 8.7(b), the obligations under such Refinancing of the applicable
Senior Lien Documents shall automatically be treated as Limited Secured Acquisition Obligations for all purposes of this Agreement,
including for purposes of the Lien priorities and rights in respect of Collateral set forth herein, and the Additional Senior Lien
Representative and the Additional Senior Lien Collateral Agent under such new Senior Lien Documents shall be a Senior Lien Representative
and Senior Lien Collateral Agent, respectively, for all purposes of this Agreement. Upon receipt of a Designation from the Company
in accordance with Section 8.7(b)(2) of this Agreement, each Junior Lien Representative and Junior Lien Collateral Agent shall,
promptly following such requests, (x) enter into such documents and agreements (including amendments or supplements to this
Agreement) as the Company or any one or more such Additional Senior Lien Representative and such Additional Senior Lien Collateral
Agent shall reasonably request in order to provide to such Additional Senior Lien Representative and such Additional Senior Lien
Collateral Agent the rights contemplated hereby, in each case consistent in all material respects with the terms of this Agreement
and (y) deliver to such Additional Senior Lien Collateral Agent any

Pledged Collateral held by it together with any necessary endorsements
(or otherwise allow such Additional Senior Lien Collateral Agent to obtain control of such Pledged Collateral), provided that the
Junior Lien Representative and Junior Lien Collateral Agent shall not be required to take any action if such actions would violate
applicable law or court order. If the Additional Limited Secured Acquisition Obligations under the Additional Senior Lien Documents
in respect of such Refinancing are secured by assets of the Company constituting Collateral that do not also secure the Junior
Lien Obligations, then the Junior Lien Obligations shall be secured at such time by a junior-priority Lien on such assets to the
same extent provided in the Junior Lien Collateral Documents and this Agreement except to the extent, with respect to any Series
of Junior Lien Obligations, such Lien on such assets constitutes a Junior Lien Declined Lien.

 

SECTION
6.            
Insolvency or Liquidation Proceedings.

 

6.1               
Finance and Sale Issues. Until the Discharge of Limited Secured Acquisition Obligations has occurred, if the Company
shall be subject to any Insolvency or Liquidation Proceeding and any Senior Lien Representative shall desire to permit the use
of “Cash Collateral” (as such term is defined in Section 363(a) of the Bankruptcy Code) on which such Senior Lien
Representative, such Senior Lien Collateral Agent or any other creditor has a Lien, or to permit the Company to obtain financing
secured by the Collateral, whether from the Limited Secured Acquisition Claimholders or any other Person under Section 364
of the Bankruptcy Code or any similar Bankruptcy Law (“DIP Financing”), then each Junior Lien Representative
and each Junior Lien Collateral Agent, for itself and on behalf of each other Junior Lien Claimholder represented by it, will not
object to such Cash Collateral use or DIP Financing (including any proposed orders for either or both such Cash Collateral use
and DIP Financing which are acceptable to any Senior Lien Representative) and to the extent the Liens securing the Limited Secured
Acquisition Obligations are subordinated to or pari passu with such DIP Financing, each Junior Lien Collateral Agent will subordinate
its Liens in the Collateral to the Liens securing such DIP Financing (and all Obligations relating thereto) and each Junior Lien
Representative and each Junior Lien Collateral Agent, for itself and on behalf of each other Junior Lien Claimholder represented
by it, will not request adequate protection or any other relief in connection therewith with respect to its interests in the Collateral
(except as expressly agreed by the Designated Senior Lien Representative or to the extent permitted by Section 6.3); provided
that the Junior Lien Representatives and the other Junior Lien Claimholders retain the right to object to any ancillary agreements
or arrangements regarding Cash Collateral use or the DIP Financing that are materially prejudicial to their interests and retain
the right to any use of Cash Collateral which constitutes Junior Lien Collateral that is not Collateral or DIP Financing to the
extent secured by Junior Lien Collateral that is not Collateral. No Junior Lien Claimholder may provide DIP Financing to the Company
secured by Liens equal or senior in priority to the Liens securing any Limited Secured Acquisition Obligations. Each Junior Lien
Representative and each Junior Lien Collateral Agent, for itself and on behalf of each other Junior Lien Claimholder represented
by it, agrees that it will not seek consultation rights in connection with, and it will not object to or oppose, a motion to sell,
liquidate or otherwise dispose of Collateral under Section 363 of the Bankruptcy Code if the requisite Limited Secured Acquisition
Claimholders have consented to such sale, liquidation or other disposition. Each Junior Lien Representative and each Junior Lien
Collateral Agent, for itself and on behalf of each other Junior Lien Claimholder represented by it, further agrees that it will
not directly or indirectly oppose or impede entry of any order in connection with such sale, liquidation or other disposition,
including orders to retain professionals or set bid procedures in connection with such sale, liquidation or disposition, if the
requisite Limited Secured Acquisition Claimholders have consented to (i) such retention of professionals and bid procedures
in connection with such sale, liquidation or disposition of such assets and (ii) the sale, liquidation or disposition of such
assets, in which event the Junior Lien Claimholders will be deemed to have consented to the sale or disposition of Collateral pursuant
to Section 363(f) of the Bankruptcy Code and such order does not materially impair the rights of the Junior Lien Claimholders
under Section 363(k) of the Bankruptcy Code.

 

6.2               
Relief from the Automatic Stay. Until the Discharge of Limited Secured Acquisition Obligations has occurred, each
Junior Lien Representative and each Junior Lien Collateral Agent, for itself and on behalf of each other Junior Lien Claimholder
represented by it, agrees that none of them shall: (i) seek (or support any other Person seeking) relief from the automatic
stay or any other stay in any Insolvency or Liquidation Proceeding in respect of the Collateral or the Restricted Assets, without
the prior written consent of all of the Senior Lien Representatives, unless a motion for adequate protection permitted under Section 6.3
has been denied by a bankruptcy court or (ii) oppose (or support any other Person in opposing) any request by any Senior Lien
Representative or Senior Lien Collateral Agent for relief from such stay in respect of the Collateral.

 

    	 	20	 

     

    

6.3               
Adequate Protection.

 

(a)                
Each Junior Lien Representative and each Junior Lien Collateral Agent, for itself and on behalf of each other Junior Lien
Claimholder represented by it, agrees that none of them shall contest (or support any other Person contesting):

 

(1)                
any request by any Senior Lien Representative, any Senior Lien Collateral Agent or other Limited Secured Acquisition Claimholder
for adequate protection of its interests in the Collateral under any Bankruptcy Law; or

 

(2)                
any objection by any Senior Lien Representative, any Senior Lien Collateral Agent or other Limited Secured Acquisition Claimholder
to any motion, relief, action or proceeding based on such Senior Lien Representative, Senior Lien Collateral Agent or Limited Secured
Acquisition Claimholder claiming a lack of adequate protection of its interests in the Collateral.

 

(b)                
Notwithstanding the foregoing provisions in this Section 6.3, in any Insolvency or Liquidation Proceeding, if the Limited
Secured Acquisition Claimholders (or any subset thereof) are granted adequate protection in the form of additional collateral in
connection with any  Cash Collateral use or DIP Financing, then each Junior Lien Collateral
Agent, for itself or on behalf of any other Junior Lien Claimholder represented by it, may seek or request adequate protection
in the form of a Lien on such additional collateral, which Lien will be subordinated to the Liens securing the Limited Secured
Acquisition Obligations and such Cash Collateral use or DIP Financing (and all Obligations relating thereto) on the same basis
as the other Liens securing the Junior Lien Obligations are so subordinated to the Limited Secured Acquisition Obligations under
this Agreement.

 

6.4               
No Waiver. Subject to Section 6.7(b), nothing contained herein shall prohibit or in any way limit any Senior
Lien Representative or any other Limited Secured Acquisition Claimholder from objecting in any Insolvency or Liquidation Proceeding
or otherwise to any action taken by any Junior Lien Representative or any other Junior Lien Claimholder with respect to the Collateral,
including the seeking by any Junior Lien Representative or any other Junior Lien Claimholder of adequate protection in respect
of their interests in the Collateral or the asserting by any Junior Lien Representative or any other Junior Lien Claimholder of
any of its rights and remedies with respect to the Collateral under the Junior Lien Documents or otherwise.

 

6.5               
Avoidance Issues. If any Limited Secured Acquisition Claimholder is required in any Insolvency or Liquidation Proceeding
or otherwise to turn over or otherwise pay to the estate of the Company any amount paid in respect of Limited Secured Acquisition
Obligations (a “Recovery”), then such Limited Secured Acquisition Claimholder shall be entitled to a
reinstatement of its Limited Secured Acquisition Obligations with respect to all such recovered amounts on the date of such Recovery,
and from and after the date of such reinstatement the Discharge of Limited Secured Acquisition Obligations shall be deemed not
to have occurred for all purposes hereunder. If this Agreement shall have been terminated prior to such Recovery, this Agreement
shall be reinstated in full force and effect, and such prior termination shall not diminish, release, discharge, impair or otherwise
affect the obligations of the parties hereto from such date of reinstatement. This Section 6.5 shall survive termination of
this Agreement.

 

6.6               
Reorganization Securities. If, in any Insolvency or Liquidation Proceeding, debt obligations of the reorganized debtor
secured by Liens upon any property of the reorganized debtor are distributed pursuant to a plan of reorganization, arrangement,
compromise or liquidation or similar dispositive restructuring plan, both on account of Limited Secured Acquisition Obligations
and on account of Junior Lien Obligations, then, to the extent the debt obligations distributed on account of the Limited Secured
Acquisition Obligations and on account of the Junior Lien Obligations are secured by Liens upon the same property, the provisions
of this Agreement will survive the distribution of such debt obligations pursuant to such plan and will apply with like effect
to the Liens securing such debt obligations.

 

6.7               
Post-Petition Interest.

 

    	 	21	 

     

    

(a)                
None of any Junior Lien Representative, any Junior Lien Collateral Agent or any other Junior Lien Claimholder shall oppose
or seek to challenge any claim by any Senior Lien Representative, any Senior Lien Collateral Agent or any other Limited Secured
Acquisition Claimholder for allowance in any Insolvency or Liquidation Proceeding of Limited Secured Acquisition Obligations consisting
of Post-Petition Interest to the extent of the value of the Lien of the Senior Lien Collateral Agents on behalf of the Limited
Secured Acquisition Claimholders on the Collateral or any other Limited Secured Acquisition Claimholder’s Lien on the Collateral,
without regard to the existence of the Liens of the Junior Lien Collateral Agents or the other Junior Lien Claimholders on the
Collateral.

 

(b)                
None of any Senior Lien Representative, Senior Lien Collateral Agent or any other Limited Secured Acquisition Claimholder
shall oppose or seek to challenge any claim by any Junior Lien Representative, Junior Lien Collateral Agent or any other Junior
Lien Claimholder for allowance in any Insolvency or Liquidation Proceeding of Junior Lien Obligations consisting of Post-Petition
Interest to the extent of the value of the Lien of the Junior Lien Collateral Agents, on behalf of the Junior Lien Claimholders,
on the Collateral (after taking into account the amount of the Limited Secured Acquisition Obligations).

 

6.8               
Waiver. Each Junior Lien Representative and each Junior Lien Collateral Agent, for itself and on behalf of each other
Junior Lien Claimholder represented by it, waives any claim it may hereafter have against any Limited Secured Acquisition Claimholder
arising out of the election of any Limited Secured Acquisition Claimholder of the application of Section 1111(b)(2) of the
Bankruptcy Code, and out of any cash collateral or financing arrangement or out of any grant of a security interest in connection
with the Collateral in any Insolvency or Liquidation Proceeding so long as such actions are not in express contravention of the
terms of this Agreement.

 

6.9               
Separate Grants of Security and Separate Classification. Each Junior Lien Representative and each Junior Lien Collateral
Agent, for itself and on behalf of each other Junior Lien Claimholder represented by it, and each Senior Lien Representative and
each Senior Lien Collateral Agent, for itself and on behalf of each other Limited Secured Acquisition Claimholder represented by
it, acknowledges and agrees that:

 

(a)                
the grants of Liens pursuant to the Senior Lien Collateral Documents and the Junior Lien Collateral Documents constitute
two separate and distinct grants of Liens; and

 

(b)                
because of, among other things, their differing rights in the Collateral, the Junior Lien Obligations are fundamentally
different from the Limited Secured Acquisition Obligations and must be separately classified in any plan of reorganization proposed
or adopted in an Insolvency or Liquidation Proceeding.

 

To further effectuate the intent of the
parties as provided in the immediately preceding sentence, if it is held that the claims of the Limited Secured Acquisition Claimholders
and the Junior Lien Claimholders in respect of the Collateral constitute only one secured claim (rather than separate classes of
senior and junior secured claims), then each of the parties hereto hereby acknowledges and agrees that all distributions shall
be made as if there were separate classes of senior and junior secured claims against the Company in respect of the Collateral
(with the effect being that, to the extent that the aggregate value of the Collateral is sufficient (for this purpose ignoring
all claims held by the Junior Lien Claimholders), the Limited Secured Acquisition Claimholders shall be entitled to receive, in
addition to amounts distributed to them in respect of principal, pre-petition interest and other claims, all amounts owing (or
that would be owing if there were such separate classes of senior and junior secured claims) in respect of Post-Petition Interest
(including any additional interest payable pursuant to the Senior Lien Documents, arising from or related to a default, which is
disallowed as a claim in any Insolvency or Liquidation Proceeding) before any distribution is made in respect of the claims held
by the Junior Lien Claimholders with respect to the Collateral, with each Junior Lien Representative and each Junior Lien Collateral
Agent, for itself and on behalf of each other Junior Lien Claimholder represented by it, hereby acknowledging and agreeing to turn
over to the Designated Senior Lien Collateral Agent, for itself and on behalf of each other Limited Secured Acquisition Claimholder,
Collateral or proceeds of Collateral otherwise received or receivable by them to the extent necessary to effectuate the intent
of this sentence, even if such turnover has the effect of reducing the claim or recovery of the Junior Lien Claimholders).

 

    	 	22	 

     

    

6.10           
Effectiveness in Insolvency or Liquidation Proceedings. The Parties acknowledge that this Agreement is a “subordination
agreement” under section 510(a) of the Bankruptcy Code, which will be effective before, during and after the commencement
of an Insolvency or Liquidation Proceeding. All references in this Agreement to the Company will include such Person as a debtor-in-possession
and any receiver or trustee for such Person in an Insolvency or Liquidation Proceeding.

the Junior Lien Collateral Agents and the other Junior Lien Claimholders shall have no duty to the Senior Lien Representatives,
the Senior Lien Collateral Agents or any of the other Limited Secured Acquisition Claimholders, and the Senior Lien Representatives,
the Senior Lien Collateral Agents and the other Limited Secured Acquisition Claimholders shall have no duty to the Junior Lien
Representative, the Junior Lien Collateral Agents or any of the other Junior Lien Claimholders, to act or refrain from acting in
a manner which allows, or results in, the occurrence or continuance of an event of default or default under any agreements with
the Company (including the Senior Lien Documents and the Junior Lien Documents), regardless of any knowledge thereof which they
may have or be charged with.

 

7.3               
No Waiver of Lien Priorities.

 

(a)                
No right of the Limited Secured Acquisition Claimholders, the Senior Lien Representatives, the Senior Lien Collateral Agents

any other circumstances which otherwise might constitute a defense available to, or a discharge of, the Company in respect
of any Senior Lien Representative, any Senior Lien Collateral Agent, the Limited Secured Acquisition Obligations, any Limited Secured

SECTION
8.            
Miscellaneous.

 

8.1               
Integration/Conflicts. This Agreement, the Senior Lien Documents and the Junior Lien Documents represent the entire
agreement by and among the Company, the Limited Secured Acquisition Claimholders and the Junior Lien Claimholders with respect
to the subject matter hereof and thereof, and supersede any and all previous agreements and understandings, oral or written, relating
to the subject matter hereof and thereof. There are no promises, undertakings, representations or warranties by the Limited Secured
Acquisition Claimholders or the Junior Lien Claimholders relative to the subject matter hereof and thereof not expressly set forth
or referred to herein or therein. In the event of any conflict between the provisions of this Agreement and the provisions of the
Senior Lien Documents or the Junior Lien Documents, the provisions of this Agreement shall govern and control.

 

8.2               
Effectiveness; Continuing Nature of this Agreement; Severability. This Agreement shall become effective when executed
and delivered by the parties hereto. This is a continuing agreement of lien subordination and the Limited Secured Acquisition Claimholders
may continue, at any time and without notice to any Junior Lien Representative or any other Junior Lien Claimholder, to extend
credit and other financial accommodations and lend monies to or for the benefit of the Company or Centrus constituting Limited
Secured Acquisition Obligations in reliance hereon. Each Junior Lien Representative and each Junior Lien Collateral Agent, on behalf
of itself and each other Junior Lien Claimholder represented by it, hereby waives any right it may have under applicable law to
revoke this Agreement or any of the provisions of this Agreement. The terms of this Agreement shall survive, and shall continue
in full force and effect, in any Insolvency or Liquidation Proceeding. Any provision of this Agreement that 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. The parties hereto shall endeavor in good-faith negotiations
to replace any invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as
possible to those of the invalid, illegal or unenforceable provisions. All references to the Company shall include the Company
as debtor and debtor-in-possession and any receiver, trustee or similar person acting for the Company (as the case may be) in any
Insolvency or Liquidation Proceeding. This Agreement shall terminate and be of no further force and effect:

 

(a)                
with respect to any Senior Lien Representative and any Senior Lien Collateral Agent, the Limited Secured Acquisition Claimholders
represented by them and their Limited Secured Acquisition Obligations, on the date on which the Limited Secured Acquisition Obligations
of such Limited Secured Acquisition Claimholders are Discharged, subject to the rights of such Limited Secured Acquisition Claimholders
under Sections 5.8 and 6.5; and

 

(b)                
with respect to any Junior Lien Representative and any Junior Lien Collateral Agent, the Junior Lien Claimholders represented
by them and their Junior Lien Obligations, on the date on which the Junior Lien Obligations of such Junior Lien Claimholders are
Discharged subject to the rights of such Junior Lien Claimholders under Sections 5.8 and 6.5;

 

provided, however, that in each case, such termination
shall not relieve any such party of its obligations incurred hereunder prior to the date of such termination.

 

8.3               
Amendments; Waivers.

 

(a)                
No amendment, modification or waiver of any of the provisions of this Agreement shall be deemed to be made unless the same
shall be in writing signed on behalf of each party hereto or its authorized agent and each waiver, if any, shall be a waiver only
with respect to the specific instance involved and shall in no way impair the rights of the parties making such waiver or the obligations
of the

 

    	 	25	 

     

    

other parties to such party in any other respect or
at any other time. Notwithstanding the foregoing, the Company shall not have any right to consent to or approve any amendment,
modification or waiver of any provision of this Agreement except to the extent their rights are directly and adversely affected.

 

(b)                
Notwithstanding the foregoing, without the consent of any Limited Secured Acquisition Claimholder or Junior Lien Claimholder,
any Representative and Collateral Agent may become a party hereto by execution and delivery of a Joinder Agreement in accordance
with Section 8.7 of this Agreement and upon such execution and delivery, such Representative and Collateral Agent and
the Additional Limited Secured Acquisition Claimholders and Additional Limited Secured Acquisition Obligations or Additional Junior
Lien Claimholders and Additional Junior Lien Obligations of the Series for which such Representative and Collateral Agent is acting
shall be subject to the terms hereof.

 

(c)                
Notwithstanding the foregoing, without the consent of any other Representative, Collateral Agent or Limited Secured Acquisition
Claimholder, the Designated Senior Lien Representative may effect amendments and modifications to this Agreement to the extent
necessary to reflect any incurrence of any Additional Limited Secured Acquisition Obligations or Additional Junior Lien Obligations
in compliance with this Agreement.

 

8.4               
Information Concerning Financial Condition of the Company and its Subsidiaries. The Senior Lien Representatives,
the Senior Lien Collateral Agents and the Limited Secured Acquisition Claimholders, on the one hand, and the holders of the Junior
Lien Obligations, on the other hand, shall each be responsible for keeping themselves informed of (a) the financial condition
of the Company and its Subsidiaries and any endorsers or guarantors of the Limited Secured Acquisition Obligations or the Junior
Lien Obligations and (b) all other circumstances bearing upon the risk of nonpayment of the Limited Secured Acquisition Obligations
or the Junior Lien Obligations. The Senior Lien Representatives, the Senior Lien Collateral Agents and the other Limited Secured
Acquisition Claimholders, on the one hand, and the Junior Lien Representatives, the Junior Lien Collateral Agents and any other
Junior Lien Claimholder, on the other hand, shall have no duty to advise of information known to it or them regarding such condition
or any such circumstances or otherwise. In the event any Claimholder, in its sole discretion, undertakes at any time or from time
to time to provide any such information to any other Claimholder, it shall be under no obligation:

 

(a)                
to make, and such Claimholder shall not make, any express or implied representation or warranty, including with respect
to the accuracy, completeness, truthfulness or validity of any such information so provided;

 

(b)                
to provide any additional information or to provide any such information on any subsequent occasion;

 

(c)                
to undertake any investigation; or

 

(d)                
to disclose any information, which pursuant to accepted or reasonable commercial finance practices, such party wishes to
maintain confidential or is otherwise required to maintain confidential.

 

8.5               
Subrogation. With respect to the value of any payments or distributions in cash, property or other assets that any
of the Junior Lien Representatives, the Junior Lien Collateral Agents or the other Junior Lien Claimholders pays over to any of
the Senior Lien Representatives, the Senior Lien Collateral Agents or the other Limited Secured Acquisition Claimholders under
the terms of this Agreement, such Junior Lien Claimholders, Junior Lien Representatives and Junior Lien Collateral Agents shall
be subrogated to the rights of such Senior Lien Representatives, Senior Lien Collateral Agents and Limited Secured Acquisition
Claimholders; provided that each Junior Lien Representative and each Junior Lien Collateral Agent, on behalf of itself and each
other Junior Lien Claimholder represented by it, hereby agrees not to assert or enforce any such rights of subrogation it may acquire
as a result of any payment hereunder until the Discharge of Limited Secured Acquisition Obligations has occurred. The Company acknowledges
and agrees that the value of any payments or distributions in cash, property or other assets received by any Junior Lien Representative,
Junior Lien Collateral Agent or other Junior Lien Claimholder

 

    	 	26	 

     

    

that are paid over to any Senior Lien Representative, Senior
Lien Collateral Agent or other Limited Secured Acquisition Claimholder pursuant to this Agreement shall not reduce any of the Junior
Lien Obligations.

 

8.6               
Application of Payments. All payments received by any Senior Lien Representative, Senior Lien Collateral Agent or
other Limited Secured Acquisition Claimholder may be applied, reversed and reapplied, in whole or in part, to such part of the
Limited Secured Acquisition Obligations provided for in the Senior Lien Documents (subject to the Senior Lien Intercreditor Agreement,
if then in effect). Each Junior Lien Representative and each Junior Lien Collateral Agent, on behalf of itself and each other Junior
Lien Claimholder represented by it, agrees to any extension or postponement of the time of payment of the Limited Secured Acquisition
Obligations or any part thereof and to any other indulgence with respect thereto, to any substitution, exchange or release of any
Lien which may at any time secure any part of the Limited Secured Acquisition Obligations and to the addition or release of any
other Person primarily or secondarily liable therefor.

 

8.7               
Additional Limited Secured Acquisition Claims and Additional Junior Debt.

 

(a)                
To the extent, but only to the extent, permitted by the provisions of the Senior Lien Documents and the Junior Lien Documents
and Section 5.5, the Company may incur or issue or guarantee any Additional Limited Secured Acquisition Claims and
one or more series or classes of Indebtedness that Refinances any Initial Junior Lien Debt and that the Company designates as Additional
Junior Lien Debt.

 

Any such series or class of Additional Limited
Secured Acquisition Claims may be secured by a first-priority, senior Lien on the Collateral, in each case under and pursuant to

to have substantially the same effects as the prohibited action.

 

8.20           
Relationship with Senior Lien Intercreditor Agreement; No Duty of Senior Claimholders to Non-Parties. This agreement
is solely intended to allocate rights and benefits between the Limited Secured Acquisition Claimholders taken together on the one
hand and the Junior Lien Claimholders taken together on the other hand. As among the Limited Secured Acquisition Claimholders,
their respective rights and benefits may be allocated as agreed among the Limited Secured Acquisition Claimholders in the Senior
Lien Intercreditor Agreement including without limitation as to Lien priority or payment priority all without affecting the terms
of this agreement. Notwithstanding any other provision of this Agreement, no Senior Lien Representative or Senior Lien Collateral
Agent (including, without limitation, the Designated Senior Lien Representative or Designated Senior Lien

 

    	 	30	 

     

    

Collateral Agent) or other Limited Secured Acquisition Claimholder
shall have any duty or obligation hereunder to any other Senior Lien Representative, Senior Lien Collateral Agent or Limited Secured
Acquisition Claimholder (other than Limited Secured Acquisition Claimholders of its own Series) unless such Senior Lien Representative
and Senior Lien Collateral Agent shall have become an express party hereto and to the Senior Lien Intercreditor Agreement.

benefit of the Secured Parties, a Lien upon and security interest in, all of Pledgor’s right, title and interest in and to
the following, in each case whether now owned or existing or hereafter acquired or arising or in which Pledgor now has or at any

purporting to establish the control (within the meaning of Section 8-106 of the Uniform Commercial Code) of (a) the Collateral
Agent thereon or (b) solely the holders of indebtedness secured by a senior lien in accordance with the applicable Intercreditor

(ix) all cash which is not in a Deposit Account
and all Money;

(x) all Equity Interests whether Investment

[65]% of such Foreign Subsidiary’s Equity Interests;

(xi) all books and records, wherever located,
relating to any of the Collateral;

(xii) all General Intangibles (other than
Equity Interests and other than Deferred Interests); and

(xiii) any and all proceeds, as such term
is defined in the Uniform Commercial Code, products, rents and profits of or from any and all of the foregoing and, to the extent
not otherwise included in the foregoing, (x) all payments under any insurance (whether or not the Trustee or the Collateral
Agent is the loss payee thereunder), indemnity, warranty or guaranty with respect to any of the foregoing Collateral, (y) all
payments in connection with any requisition, condemnation, seizure or forfeiture with respect to any of the foregoing Collateral
and (z) all other amounts from time to time paid or payable under or with respect to any of the foregoing Collateral (collectively,
“Proceeds”). Pledgor shall file financing statements under the Uniform Commercial Code describing the Collateral
and appropriate statements with the appropriate jurisdictions describing any other statutory liens held by the Trustee or the Collateral
Agent and shall provide copies and evidence of the filing thereof to the Trustee and Collateral Agent within a reasonable time
period after such filing.

In no event shall the Collateral include,
and no Pledgor shall be deemed to have granted a security interest in (i) the DOE Collateral or (ii) any of Pledgor’s
rights or interests in any license, contract or agreement to which Pledgor is a party or any of its or interests thereunder to
the extent, but only to the extent, that such a grant would, under the terms of such license, contract or agreement or otherwise,
result in a breach of the terms of, or constitute a default under any license, contract or agreement to which Pledgor is a party
(other than to the extent that any such term would be rendered ineffective pursuant to the Uniform Commercial Code or any other
applicable law (including the Bankruptcy Code) or principles of equity); provided that immediately upon the ineffectiveness,
lapse or termination of any such provision, the Collateral shall include, and Pledgor shall be deemed to have granted a security
interest in, all such rights and interests as if such provision had never been in effect; and provided further that any
Account or money or other amounts due or to become due to Pledgor under any such license, contract or agreement or any proceeds

such license, contract or agreement shall at no time be excluded
from the Collateral or the security interest granted by Pledgor hereunder in favor of the Collateral Agent.

owing to the Collateral Agent under the Security Documents (as defined in the Indenture), of the Pledgor as a Guarantor pursuant
to and under the Guarantee, whether such liabilities and obligations are now existing or hereafter incurred, created or arising
and whether direct or indirect, absolute or contingent, due or to become due, including, without limitation, interest accruing
after the filing of a petition or commencement of a case by or with respect to Issuer or Pledgor seeking relief under any applicable
federal and state laws pertaining to bankruptcy, reorganization, arrangement, moratorium, readjustment of debts, dissolution, liquidation
or other debtor relief, specifically including, without limitation, the Bankruptcy Code and any fraudulent transfer and fraudulent

fees, costs and expenses payable by Pledgor under Section 8.1 (the liabilities and obligations of the Pledgor described
in this Section 2.2, collectively, the “Secured Obligations”). In addition, in the event that Rule
3-16 of Regulation S-X under the Securities Act requires or would require the filing with the Securities and Exchange Commission
of separate financial statements of any “affiliate” of the Pledgor due to the fact that such affiliate’s “securities”
secure any Secured Obligations, then such “securities” shall automatically be deemed not to constitute security for
any Secured Obligations and shall not constitute Equity Interests or Collateral hereunder. As used herein, “securities”
and “affiliate” shall have the meaning set forth in Regulation S-X or such other law, rule or regulation, as applicable.
Notwithstanding anything to the contrary contained in this Agreement, the maximum liability of Pledgor for the Secured Obligations
pursuant to the Guaranty and this Agreement shall be an amount equal to the amount of cash transferred or cash payment made pursuant

Interests

(a)       Subject
to Section 2.3(b), Pledgor hereby pledges and assigns to the Collateral Agent, for the ratable benefit of the Secured
Parties, and grants to the Collateral Agent, its successors and assigns, for the ratable benefit of the Secured Parties, a Lien
upon and security interest in, all of Pledgor’s right, title and interest in and to the following, in each case whether now
owned or existing or hereafter acquired or arising or in which Pledgor now has or at any time in the future may acquire any right,
title or interest (it being understood that, subject to Section 2.3(b), Section 2.3(c) and Section 1.2,
the following assets and properties shall also constitute “Collateral” as used in this Agreement):

(ii) all Patent Collateral;

(iii) all Trademark Collateral; and

(iv) any and all proceeds, as such term is
defined in the Uniform Commercial Code, products, rents and profits of or from any and all of the foregoing and, to the extent
not otherwise included in the foregoing, (w) all payments under any insurance (whether or not the Trustee or the Collateral
Agent is the loss payee thereunder), indemnity, warranty or guaranty with respect to any of the foregoing Collateral, (x) all
payments in connection with any requisition, condemnation, seizure or forfeiture with respect to any of the foregoing Collateral,
(y) all claims and rights to recover for any past, present or future infringement or dilution of or injury to any Copyright

with respect to any of the foregoing Collateral (it being understood that, subject to Section 2.3(b) and Section 2.3(c),
the foregoing assets and properties referred to in this clause (iv) shall also constitute “Proceeds” as used in
this Agreement).

(b)       Notwithstanding
the provisions of Section 2.3(a) or any of the provisions contained herein or in the Indenture or Notes, no Lien upon
and security interest in the Deferred Interests shall be deemed to have occurred nor shall any such Lien and security interest
be deemed to have attached to or on the Deferred Interests until the following event shall have occurred (a “Deferred
Interests Triggering Event”): an Event of Default shall

    	 	50	 

     

    

have occurred and be continuing. Immediately upon the occurrence
of any Deferred Interests Triggering Event, a Lien on the Deferred Interests consisting of Copyright Collateral, Patent Collateral,
Trademark Collateral and all Proceeds related thereto shall automatically be deemed to have attached in favor of the Collateral
Agent pursuant to this Section 2.3 without any further action by the Collateral Agent or Pledgor and, on and after
the occurrence of such Deferred Interests Triggering Event, the Pledgor shall file financing statements under the Uniform Commercial
Code describing the Collateral represented by such Deferred Interests and Pledgor shall take all necessary actions, including,
but not limited to, those required by Sections 4.9, 4.10 and 4.12 herein to complete any required annexes to
this Agreement, as promptly as possible (and in no event more than ten (10) days from the occurrence of any such Deferred
Interests Triggering Event) at Pledgor’s expense in order to give the Collateral Agent a first priority security interest
(subject to Permitted Liens) in the Collateral represented by such Deferred Interests. As of the date on which a Lien on any Deferred
Interests attaches pursuant to this Section 2.3, the Pledgor shall be deemed to have reaffirmed the representations
and warranties set forth in Article III with respect to such Deferred Interests. Notwithstanding anything to the contrary set forth
herein, with respect to any Patent Collateral, no Lien or security interest in favor of the Collateral Agent shall attach or be
deemed to attach, and Collateral Agent agrees not to take any action to register, record or file any financing statement or other
evidence of a Lien or security interest, without the prior written consent of the Pledgor (except that no such consent shall be
required if a bankruptcy or insolvency proceeding shall have been commenced by or against Pledgor) if: (i) the attachment,
registration, recordation or filing of such Lien could reasonably be expected to (x) result in a breach or violation of any
of the terms or provisions of any license, permit or contractual agreement between Pledgor and the DOE or any other applicable
governmental authority or (y) limit, invalidate or impair Pledgor’s right to maintain ownership of or license or right
to use, such Patent Collateral; or (ii) such Patent Collateral includes classified information and the attachment, registration,
recordation or filing of such Lien on such Patent Collateral would constitute a breach or violation of Pledgor’s duty to
maintain the confidentiality of such classified information.

 

(c)       Without
limiting Section 1.2, in no event shall the Collateral include, and Pledgor shall not be deemed to have granted a security
interest in any of Pledgor’s rights or interests in, any license, contract or agreement to which Pledgor is a party or any
of its or interests thereunder to the extent, but only to the extent, that such a grant would, under the terms of such license,
contract or agreement or otherwise, result in a breach of the terms of, or constitute a default under any such license, contract
or agreement (other than to the extent that any such term would be rendered ineffective pursuant to the Uniform Commercial Code
or any other applicable law (including the Bankruptcy Code) or principles of equity); provided that immediately upon the
ineffectiveness, lapse or termination of any such term, the Collateral shall include, and Pledgor shall be deemed to have granted
a security interest in, all such rights and interests as if such term had never been in effect; provided further that any
Account or money or other amounts due or to become due to Pledgor under any such license, contract or agreement or any proceeds
resulting from the sale or other disposition by Pledgor of any rights of Pledgor under any such license, contract or agreement
shall at no time be excluded from the Collateral or the security interest granted by Pledgor hereunder in favor of the Collateral
Agent.

 

(d)       Except
as specifically provided herein or as permitted by the Indenture, Pledgor will not sell or otherwise dispose of, grant any option
with respect to, or grant any Lien with respect to or otherwise encumber any of the Deferred Interests or any interest therein.

 

2.4       Inventory
Account 

. Pledgor shall establish, in its own name, an Inventory Account
to which all Pledgor-owned uranium and SWU Component in the Inventory shall be credited. The balance of material credited to this
Inventory Account shall be reconciled monthly.

superior and prior to the rights of all other persons therein (except for Permitted Liens), and no other or additional filings,
registrations, recordings or actions are or shall be necessary or appropriate in order to perfect or maintain the perfection and
priority of such Lien and security interest, other than actions required with respect to Collateral of the types excluded from
Articles 8 or 9 of the Uniform Commercial Code or from the filing requirements under Article 9 of the Uniform Commercial Code by

and Pledgor has not entered into any contract or granted any Lien within the past five (5) years under any name other than
its legal name or a trade or fictitious name indicated on Annex C. Each trade or fictitious name is a trade name and style

or services and conduct a portion of its business; all related Accounts are owned solely by the Pledgor and are subject to the
Liens and other terms of this Agreement; and in no event shall Pledgor assert that products invoiced under the name of any trade
or fictitious name that are

    	 	52	 

     

    

subject to a dispute with Customers are not subject to the terms
of this Agreement as though such trade or fictitious name did not exist.

Restrictions 

. There are no statutory or regulatory restrictions, prohibitions
or limitations on Pledgor’s ability to grant to the Collateral Agent a Lien upon and security interest in the Collateral
(including without limitation, all Deferred Interests which would become Collateral if a Deferred Interests Triggering Event were
to occur) pursuant to this Agreement or (except for the provisions of the federal Assignment of Claims Act of 1940, as amended,

3.7       Intellectual
Property 

. Concurrently with the execution and delivery of this Agreement
by the Pledgor, the Pledgor has delivered to the Collateral Agent a schedule of material Copyrights, Patents and Trademarks, which
schedule correctly sets forth all material registered Copyrights, Patents and Trademarks owned by the Pledgor (other than Copyrights,
Patents and Trademarks, the subject matter of which is “classified” for reasons of national security or foreign policy)
as of the date hereof. As of date on which the Lien on the Deferred Interests attaches pursuant hereto, Annexes D, E
and F correctly set forth all registered Copyrights, Patents and Trademarks owned by Pledgor as of the date thereof and
used or proposed to be used in its business. Except to the extent set forth on Schedule I hereto, as of the date hereof and as
of the date on which the Lien on such Deferred Interests attaches, Pledgor owns or possesses the valid right to use all Copyrights,
Patents and Trademarks material to its business and, to the best of Pledgor’s knowledge, the use thereof by the Pledgor does
not infringe upon the rights of any other Person, except for any such infringements that, individually or in the aggregate, would
not reasonably be expected to have a Material Adverse Effect. As of the date hereof and as of the date on which the Lien on the
Deferred Interests attaches, all Copyrights, Patents and Trademarks (a) have been duly registered in, filed in or issued by
the U.S. Copyright Office, United States Patent and Trademark Office or other corresponding offices of other applicable jurisdictions,

(b) have been properly maintained and renewed in accordance with all applicable provisions of law and administrative regulations
in the United States or in each such other jurisdiction, as applicable, except, in each case, for such Patents, Trademarks or Copyrights
which, as reasonably determined by the Pledgor consistent with prudent

    	 	53	 

     

    

and commercially reasonable business practices (x) are
not material to the business of the Pledgor or (y) the Pledgor has abandoned prior to the date on which the Lien on such Deferred
Interests attaches.

a fabricator or other nuclear fuel processor or a storage facility.

 

3.9       Deposit
Accounts and Securities Accounts 

. Annex G correctly sets forth all Deposit Accounts and
Securities Accounts of Pledgor. Other than any Excluded Accounts, each Deposit Account is subject to a deposit account control

unless in each case Pledgor has (A) given fifteen (15) days’ prior written notice to the Collateral Agent of its

other documentation relating thereto, and will furnish to the Collateral Agent such statements, schedules and reports (including,

    	 	54	 

     

    

(b)       Pledgor
shall, from time to time at such times as may be reasonably requested and upon reasonable notice, make available to the Collateral

debtor, the amount of each payment and any such other information, if any, as the Collateral Agent shall reasonably request); provided,
that Collateral Agent agrees to maintain the confidentiality of such information on terms reasonably acceptable to the Pledgor
and provided further that Pledgor shall not be obligated to provide any information that is “classified” for reasons
of national security or foreign policy or otherwise restricted from disclosure under applicable laws or agreements.

 

4.4       Instruments 

. Pledgor agrees that if any Collateral shall at any time be
evidenced by a promissory note, tangible Chattel Paper or other Instrument (other than checks or other Instruments for deposit

of the Collateral Agent and physically delivered to the Collateral Agent to be held as Collateral hereunder.

 

4.5       Inventory
and Equipment 

. Pledgor will, in accordance with sound business practices,
maintain all Equipment and Eligible Inventory held by it or on its behalf in good repair and working and saleable or useable condition,
except for ordinary wear and tear in respect of the Equipment. Unless an Event of Default has occurred and is continuing and the

Indenture, process, use, ship, deliver and, in the ordinary course of business or as otherwise permitted under the Indenture, sell,
transfer, lease or otherwise dispose of its Inventory or Equipment. Pledgor further agrees that its Inventory will be produced
in compliance with the applicable requirements of the Fair Labor Standards Act, as amended, if such Inventory is produced by Pledgor
at a facility operated by Pledgor in the United States. No Pledgor will, without the Collateral Agent’s prior written consent,
alter or remove any identifying symbol or number on any of Pledgor’s Equipment constituting Collateral except pursuant to
a sale of such Collateral to a third party permitted by this Agreement or the Indenture.

 

4.6       Taxes

the Indenture (as though Pledgor were a Subsidiary), pay and discharge (i) all taxes, assessments and governmental charges
or levies imposed upon it, upon its income or profits or upon any of its properties, prior to the date on which penalties would
attach thereto, and (ii) all lawful claims for taxes, assessment, governmental charges or levies that, if unpaid, might become
a Lien upon any of the Collateral.

 

4.7       Insurance 

.

 

(a)       Pledgor
will maintain and pay for, or cause to be maintained and paid for, with responsible insurance companies, insurance with respect
to its assets, properties and business, against such hazards and liabilities, of such types and in such amounts, as is in accordance
with customary industry practice in the general areas in which the Pledgor operates.

 

(b)       Pledgor
hereby irrevocably makes, constitutes and appoints the Collateral Agent at all times during the continuance of an Event of Default,

insurance, endorsing its name on any check, draft, instrument or other item or payment for the proceeds of such policies of insurance
and for making all determinations and decisions with respect to such policies of insurance.

 

(c)       If
Pledgor fails to obtain and maintain any of the policies of insurance required to be maintained hereunder or to pay any premium
in whole or in part, the Collateral Agent may, without waiving or releasing any obligation or Default, at Pledgor’s expense,
but without any obligation to do so, procure such policies or pay such premiums. All sums so disbursed by the Collateral Agent,
including reasonable attorneys’ fees, court and out of pocket costs, expenses and other charges related thereto, shall be
payable by the Pledgor to the Collateral Agent on demand and shall be additional Secured Obligations hereunder, secured by the
Collateral.

 

    	 	55

forms to insurance companies. Pledgor will deliver to the Collateral Agent one or more certificates of insurance evidencing renewal
of the insurance coverage required hereunder (or issuance of a replacement policy from another insurance company meeting the requirements
of this Section 4.7) plus such other evidence of payment of premiums therefor as the Collateral Agent may request.
Upon the reasonable request of the Collateral Agent, from time to time, Pledgor will deliver to the Collateral Agent evidence that
the insurance required to be maintained pursuant to this Section is in effect.

 

4.8       Intellectual
Property 

.

 

(a)       If
at any time a Credit Agreement is outstanding and such Credit Agreement requires that the Pledgor deliver an updated schedule of
material Copyrights, Patents and Trademarks to the Credit Agreement Agent, then whenever the Pledgor so delivers such an updated
schedule to the Credit Agreement Agent, it shall also deliver the copies of such updated schedules to the Collateral Agent. If
there is no Credit Agreement outstanding or such Credit Agreement does not require that the Pledgor deliver updated schedules of
material Copyrights, Patents and Trademarks periodically, then the Pledgor shall nonetheless deliver updated schedules of Copyrights,
Patents and Trademarks included in the Collateral not less frequently than once per calendar year commencing on the first anniversary
date of the Deferred Interest Triggering Event and, if an Event of Default shall have occurred and be continuing, updated schedules
will be delivered to the Collateral Agent. As of the date on which the Lien on the Deferred Interests attaches, Pledgor will, at
its own expense, execute and deliver a fully completed Copyright Security Agreement, Patent Security Agreement or Trademark Security
Agreement in the respective forms of Exhibits B, C and D, as applicable, with regard to any Copyright Collateral,
Patent Collateral or Trademark Collateral (in each case, to the extent registered or filed, subject to the provisions of Section 3.7
hereof), as the case may be, of Pledgor, described in Annexes D, E and F hereto. In the event that after such
date, Pledgor shall acquire any registered Copyright Collateral, Patent Collateral or Trademark Collateral or effect any registration
of any such Copyright Collateral, Patent Collateral or Trademark Collateral or file any application for registration thereof, within
the United States, Pledgor shall promptly furnish written notice thereof to the Collateral Agent together with information sufficient
to permit the Collateral Agent, upon its receipt of such notice, to (and Pledgor hereby authorizes the Collateral Agent to) modify
this Agreement, as appropriate, by amending Annex D, E or F hereto or to add additional exhibits hereto to
include any Copyright Collateral, Patent Collateral or Trademark Collateral (in each case, to the extent registered or filed, subject
to the provisions of Section 3.7 hereof) that becomes part of the Collateral under this Agreement, and Pledgor shall
additionally, at its own expense, execute and deliver, as promptly as possible (but in any event within ten (10) days) after
the date of such notice, with regard to United States Copyrights, Patents and Trademarks, fully completed Copyright Security Agreements,
Patent Security Agreements or Trademark Security Agreements in the forms of Exhibits B, C and D, as applicable,
together in all instances with any other agreements, instruments and documents that the Collateral Agent may reasonably request
from time to time to further effect and confirm the security interest created by this Agreement in such Copyright Collateral, Patent
Collateral and Trademark Collateral, and Pledgor hereby appoints the Collateral Agent its attorney-in-fact, upon the occurrence
and the continuance of an Event of Default, to execute, deliver and record any and all such agreements, instruments and documents
for the foregoing purposes, all acts of such attorney being hereby ratified and confirmed and such power, being coupled with an
interest, being irrevocable for so long as this Agreement shall be in effect with respect to Pledgor. In that connection, Pledgor
shall also execute and deliver on the date on which the Lien on the Deferred Interests attaches, one copy of the Special Power
of Attorney in the form of Annex H hereto.

 

(b)       The
Pledgor shall file and prosecute diligently all applications for registration of Patents, Trademarks or Copyrights now or hereafter
pending that would be necessary to the business of the Pledgor to which any such applications pertain, and do all acts (or refrain
from doing all acts), in any such instance, reasonably necessary to preserve and maintain all material rights in Patents, Trademarks
or Copyrights, unless such Patents, Trademarks or Copyrights are not material to the business of the Pledgor, as reasonably determined
by the Pledgor consistent with prudent and commercially reasonable business practices.

 

(c)       From
and after the date on which the Lien on the Deferred Interests attaches, Pledgor shall notify the Collateral Agent promptly in
writing if it knows or has reason to know that any material Patent Collateral, Trademark Collateral or Copyright Collateral used
in the conduct of its business may become abandoned or

    	 	56	 

     

    

dedicated to the public, or of any adverse determination or
development (including the institution of, or any such determination or development in, any proceeding in the U.S. Patent and Trademark
Office, U.S. Copyright Office or any court) regarding Pledgor’s ownership of any material Patent Collateral, Trademark Collateral
or Copyright Collateral, its right to register the same, or to keep and maintain the same.

 

(d)       From
and after the date on which the Lien on the Deferred Interests attaches, in the event that any Collateral consisting of material
Patent Collateral, Trademark Collateral or Copyright Collateral used in the conduct of Pledgor’s business is believed infringed,
misappropriated or diluted by a third party, Pledgor shall notify the Collateral Agent promptly in writing after it learns thereof
and shall, if consistent with the exercise of reasonable business judgment and applicable laws, regulations and agreements to which
the applicable Pledgor is a party, promptly sue for infringement, misappropriation or dilution and to recover any and all damages
for such infringement, misappropriation or dilution, and take such other actions as are appropriate under the circumstances to
protect such Collateral.

 

(e)       From
and after the date on which the Lien on the Deferred Interests attaches, upon the occurrence and during the continuance of any
Event of Default, Pledgor shall use its commercially reasonable efforts to obtain all requisite consents or approvals from the
licensor of each material License included within the Copyright Collateral, Patent Collateral or Trademark Collateral to effect
the assignment of all of Pledgor’s right, title and interest thereunder to the Collateral Agent or its designee.

hereof, all certificates or instruments representing or evidencing any material Account, Equity Interest or other Collateral delivered
to the Collateral Agent pursuant to this Agreement, shall be in form suitable for transfer by delivery and shall be delivered together
with undated stock powers duly executed in blank, appropriate endorsements or other necessary instruments of registration, transfer
or assignment, duly executed, and in each case such other instruments or documents required or as the Collateral Agent may, but
is not required to, request (provided that delivery of an opinion of counsel may only be requested where required by the Indenture).
Pledgor shall deliver an Officers’ Certificate (as defined in the Indenture) to the Collateral Agent certifying as to the
requirements for delivery.

 

4.10       Protection
of Security Interest 

. Pledgor agrees that it will use commercially reasonable efforts,
at its own cost and expense, to take any and all actions necessary to warrant and defend the right, title and interest of the Collateral
Agent and Secured Parties in and to the Collateral against the claims and demands of all other persons.

 

4.11       Control
of Investment Property, Deposit Accounts and Electronic Chattel Paper 

. Subject to the Intercreditor Agreements, the last sentence
of Section 3.2 and Section 8.16 hereof, if any Investment Property (whether now owned or hereafter acquired)
is included in the Collateral, Pledgor will notify the Collateral Agent in writing thereof and will promptly take and cause to
be taken all actions required under Articles 8 and 9 of the Uniform Commercial Code and any other applicable law to enable the
Collateral Agent (or the Credit Agreement Agent as agent or bailee for the Collateral Agent) to acquire “control” (within
the meaning of such term under Section 8-106 (or its successor provision) of the Uniform Commercial Code) of such Investment
Property and as may be otherwise necessary to perfect the security interest of the Collateral Agent therein. Subject to the Intercreditor
Agreements and Section 8.16 hereof, if any Deposit Account (whether now owned or hereafter acquired), other than any
Excluded Account, is included in the Collateral, Pledgor will notify the Collateral Agent in writing thereof and will promptly
take and cause to be taken all actions required under Article 9 of the Uniform Commercial Code and any other applicable law to
enable the Collateral Agent to acquire “control” (within the meaning of such term under Section 9-104 (or its
successor provision) of the Uniform Commercial Code) of such Deposit Account and as may be otherwise necessary to perfect the security
interest of the Collateral Agent therein. Subject to the Intercreditor Agreements and Section 8.16 hereof, if any Account
of Pledgor would constitute “electronic chattel paper” as defined under the Uniform Commercial Code, Pledgor will promptly
notify the Collateral Agent in writing and will take such other steps as may be necessary to give the Collateral Agent “control”
over such electronic chattel paper (within the meaning of Section 9-105 of the Uniform Commercial Code). Notwithstanding the
foregoing, the provisions of any control agreement shall provide that the Company may terminate such control agreement by delivery
of a written certification to each of the relevant deposit bank, securities intermediary, issuer or custodian, as applicable, and
the Collateral Agent that the property subject to such

    	 	57	 

     

    

control agreement is subject to another control agreement for
the benefit of the holders of any senior Lien or their agent or other representative who are parties to the applicable Intercreditor
Agreements (provided that the foregoing termination shall not apply to any control agreement that established the control of both
the Collateral Agent and the holders of such senior Lien so long as such control is consistent with the priorities established
by the Intercreditor Agreements). The Company agrees to use commercially reasonable efforts to cause one of the following to occur
(such obligation to use commercial reasonable efforts to continue with respect to each of the following until such efforts are
successful as to one of the following or such efforts are unsuccessful as to all of the following): (i) obtain the consent
of the applicable holders of senior Liens or their agent(s) or other representative(s) and the applicable deposit bank, securities
intermediary, issuer or custodian, as applicable, to the Collateral Agent retaining its own separate control agreement reflecting
the priorities established by the Intercreditor Agreements, (ii) obtain the consent of the applicable holders of senior Liens
or their agent(s) or other representative(s) and the applicable deposit bank, securities intermediary, issuer or custodian, as
applicable, to the Collateral Agent being a party to the control agreement in favor of the holders of senior Liens or their agent(s)
and pursuant to such control agreement having the applicable deposit bank, securities intermediary, issuer or custodian, as applicable,
agree to follow instructions or entitlement orders, as applicable, of the Collateral Agent without further consent of the Company
upon a discharge of the senior Liens, or (iii) cause any control agreement for the benefit of any holders of senior Liens
to be subject to the Uniform Commercial Code. The Company agrees that it will not exercise its right to terminate any such separate
control agreements in favor of the Collateral Agent so long as the consent referred to in clause (i) is obtained or if such
separate control agreement is amended in accordance with clause (ii) rather than replaced.

Article
V

CERTAIN PROVISIONS RELATING TO EQUITY INTERESTS

 

5.1       Ownership;
After-Acquired Equity Interests 

.

 

(a)       Except
as otherwise permitted by the Indenture, Pledgor will cause the Equity Interests pledged by it hereunder to constitute at all times
100% of the capital stock or other Equity Interests in each subsidiary of Pledgor, such that the issuer thereof shall be a wholly
owned subsidiary of Pledgor. Unless the Collateral Agent shall have given its prior written consent, Pledgor will not cause or
permit any such issuer to issue or sell any new capital stock, any warrants, options or rights to acquire the same, or other Equity
Interests of any

    	 	58	 

     

    

nature to any person other than Pledgor, or cause, permit or
consent to the admission of any other person as a stockholder, partner or member of any such issuer.

 

(b)       If
Pledgor shall, at any time and from time to time, acquire any additional capital stock or other Equity Interests in any person
of the types described in the definition of the term “Equity Interests”, the same shall be automatically deemed
to be Equity Interests, and shall be deemed to be pledged to the Collateral Agent pursuant to Section 2.1 and, subject
to the Intercreditor Agreements, Pledgor will forthwith pledge and, subject to Section 8.16 hereof, deposit the same
with the Collateral Agent and deliver to the Collateral Agent any certificates or instruments therefor, together with the endorsement
of Pledgor (in the case of any promissory notes or other Instruments), undated stock powers (in the case of Equity Interests evidenced
by certificates) or other necessary instruments of transfer or assignment, duly executed in blank, together with such other certificates
and instruments as the Collateral Agent may, but is not required to, reasonably request (including Uniform Commercial Code financing
statements or appropriate amendments thereto), and will promptly thereafter deliver to the Collateral Agent a fully completed and
duly executed amendment to this Agreement in the form of Exhibit A (each, a “Pledge Amendment”) in respect
thereof. Pledgor hereby authorizes the Collateral Agent to attach each such Pledge Amendment to this Agreement, and agrees that
all such Collateral listed on any Pledge Amendment shall for all purposes be deemed Collateral hereunder and shall be subject to
the provisions hereof, provided that the failure of Pledgor to execute and deliver any Pledge Amendment with respect to
any such additional Collateral as required hereinabove shall not impair the security interest of the Collateral Agent in such Collateral
or otherwise adversely affect the rights and remedies of the Collateral Agent hereunder with respect thereto.

 

(c)       Subject
to the Intercreditor Agreements and Section 8.16 hereof, if any Equity Interests (whether now owned or hereafter acquired)
included in the Collateral are “uncertificated securities” within the meaning of the Uniform Commercial Code or are
otherwise not evidenced by any certificate or instrument, each applicable Pledgor will promptly notify the Collateral Agent in
writing thereof and will promptly take and cause to be taken, and will (if the issuer of such uncertificated securities is a person
other than a direct or indirect subsidiary of the Parent) use its best efforts to cause the issuer to take, all actions required
under Articles 8 and 9 of the Uniform Commercial Code and any other applicable law, to enable the Collateral Agent to acquire
“control” (within the meaning of such term under Section 8-106 (or its successor provision) of the Uniform Commercial
Code) of such uncertificated securities and as may be otherwise necessary or deemed appropriate by the Collateral Agent to perfect
the security interest of the Collateral Agent therein.

 

5.2       Voting
Rights 

. So long as no Event of Default shall have occurred and be
continuing, Pledgor shall be entitled to exercise all voting and other consensual rights pertaining to its Equity Interests (subject
to its obligations under Section 5.1) which have become Collateral, and for that purpose the Collateral Agent will
execute and deliver or cause to be executed and delivered to the Pledgor all such proxies and other instruments as the Pledgor
may reasonably request in writing to enable the Pledgor to exercise such voting and other consensual rights; provided, however,
that the Pledgor will not cast any vote, give any consent, waiver or ratification, or take or fail to take any action, in any manner
that would, or could reasonably be expected to, violate or be inconsistent with any of the terms of this Agreement, the Intercreditor
Agreements or the Indenture, or have the effect of impairing the position or interests of the Collateral Agent or any other Secured
Party in such Collateral.

 

5.3       Dividends
and Other Distributions 

. Except as provided otherwise herein or in the Indenture, all
interest, income, dividends, distributions and other amounts payable in cash in respect of the Equity Interests which have become
Collateral shall be paid to the Collateral Agent and retained by it in a non-interest bearing account as part of the Collateral
(except to the extent applied upon receipt to the repayment of the Secured Obligations). The Collateral Agent shall also be entitled
at all times to receive directly, and to retain as part of the Collateral, (i) all interest, income, dividends, distributions
or other amounts paid or payable in cash or other property in respect of any Equity Interests which have become Collateral in connection
with the dissolution, liquidation, recapitalization or reclassification of the capital of the applicable issuer to the extent representing
an extraordinary, liquidating or other distribution in return of capital, (ii) all additional Equity Interests or other securities
or property (other than cash) paid or payable or distributed or distributable in respect of any Equity Interests which have become
Collateral in connection with any noncash dividend, distribution, return of capital, spin-off, stock split, split-up, reclassification,
combination of shares or interests or similar rearrangement, and (iii) without affecting any restrictions against such actions
contained in the

    	 	59	 

     

    

Indenture, all additional Equity Interests or other securities
or property (including cash) paid or payable or distributed or distributable in respect of any Equity Interests which have become
Collateral in connection with any consolidation, merger, exchange of securities, liquidation or other reorganization. All interest,
income, dividends, distributions or other amounts that are received by Pledgor in violation of the provisions of this Section shall
be received in trust for the benefit of the Collateral Agent, shall be segregated from other property or funds of Pledgor and,
subject to the Intercreditor Agreements and Section 8.16 hereof, shall be forthwith delivered to the Collateral Agent
as Collateral in the same form as so received (with any necessary endorsements) or in the case of cash, by wire transfer pursuant
to payment instructions provided by Collateral Agent to Pledgor. Any such cash shall be retained in a non-interest bearing account.

 

Article
VI

REMEDIES

 

6.1       Remedies 

. If an Event of Default shall have occurred and be continuing,
subject to the Intercreditor Agreements (which may limit or preclude the exercise of rights under this Article VI), the Collateral
Agent, at the direction of the Trustee acting upon the written direction of the appropriate percentage of Holders under the Indenture,
as applicable, shall be entitled to exercise in respect of the Collateral all of its rights, powers and remedies provided for herein
or otherwise available to it under the Indenture, by law, in equity or otherwise, including all rights and remedies of a secured
party under the Uniform Commercial Code, and shall be entitled in particular, but without limitation of the foregoing (other than
as provided in the Intercreditor Agreements), to exercise the following rights, which Pledgor agrees to be commercially reasonable:

 

(a)       To
notify any or all account debtors or obligors under any Accounts or other Collateral of the security interest in favor of the Collateral
Agent created hereby and to direct all such Persons to make payments of all amounts due thereon or thereunder directly to the Collateral
Agent or to an account designated by the Collateral Agent; and in such instance and from and after such notice, all amounts and
Proceeds (including wire transfers, checks and other instruments) received by Pledgor in respect of any Accounts or other Collateral
shall be received in trust for the benefit of the Collateral Agent hereunder, shall be segregated from the other funds of Pledgor
and, subject to the Intercreditor Agreements, shall be forthwith deposited into such account or paid over or delivered to the Collateral
Agent in the same form as so received (with any necessary endorsements or assignments), to be held as Collateral and applied to
the Secured Obligations as provided herein;

 

(b)       To
receive, open and properly dispose of all mail addressed to Pledgor concerning Accounts and other Collateral and to notify the
appropriate postal authority to change the mailing or delivery address of such mail; to accelerate any indebtedness or other obligation
constituting Collateral that may be accelerated in accordance with its terms; to take or bring all actions and suits deemed necessary
or appropriate to effect collections and to enforce payment of any Accounts or other Collateral; to settle, compromise or release
in whole or in part any amounts owing on Accounts or other Collateral; and to extend the time of payment of any and all Accounts
or other amounts owing under any Collateral and to make allowances and adjustments with respect thereto, all in the same manner
and to the same extent as Pledgor might have done;

 

(c)       Subject
to applicable law and regulation, to transfer to or register in its name or the name of any of its agents or nominees all or any
part of the Collateral, without notice to Pledgor and with or without disclosing that such Collateral is subject to the security
interest created hereunder;

 

(d)       Subject
to applicable law and regulation, to require Pledgor to, and Pledgor hereby agrees that it will at its expense and upon request
of the Collateral Agent forthwith, assemble all or any part of the Collateral as directed by the Collateral Agent and to the extent
permitted by applicable law make it available to the Collateral Agent at a place designated by the Collateral Agent and Pledgor
further agrees that the Collateral Agent shall have no obligation to clean-up or otherwise prepare the Collateral for sale;

 

(e)       To
the extent permitted by applicable law, to enter and remain upon the premises of Pledgor and take possession of all or any part
of the Collateral, with or without judicial process; to use the materials, services, books and records of Pledgor for the purpose
of liquidating or collecting the Collateral, whether by

    	 	60	 

     

    

foreclosure, auction or otherwise; and to remove the same to
the premises of the Collateral Agent or any designated agent for such time as the Collateral Agent may desire or as is necessary
or advisable, in order to effectively collect or liquidate the Collateral;

 

(f)       Subject
to applicable law and regulation and the Intercreditor Agreements, to exercise, but only at the request of the Trustee acting in
accordance with the Indenture, to the extent permitted by applicable law, (i) all voting, consensual and other rights and
powers pertaining to the Equity Interests (whether or not transferred into the name of the Collateral Agent), at any meeting of
shareholders, partners, members or otherwise, and (ii) any and all rights of conversion, exchange, subscription and any other
rights, privileges or options pertaining to the Equity Interests as if it were the absolute owner thereof (including, without limitation,
the right to exchange any and all of the Equity Interests upon the merger, consolidation, reorganization, reclassification, combination
of shares or interests, similar rearrangement or other similar fundamental change in the structure of the applicable issuer, or
upon the exercise by Pledgor or the Collateral Agent of any right, privilege or option pertaining to such Equity Interests), and
in connection therewith, the right to deposit and deliver any and all of the Equity Interests with any committee, depositary, transfer
agent, registrar or other designated agency and give all consents, waivers and ratifications in respect of the Equity Interests,
all without liability except to account for any property actually received by it, but the Collateral Agent shall have no duty to
exercise any such right, privilege or option or give any such consent, waiver or ratification and shall not be responsible for
any failure to do so or delay in so doing; and for the foregoing purposes Pledgor will promptly execute and deliver or cause to
be executed and delivered to the Collateral Agent, all such proxies and other instruments to enable the Collateral Agent to exercise
such rights and powers; AND IN FURTHERANCE OF THE FOREGOING AND WITHOUT LIMITATION THEREOF, PLEDGOR HEREBY IRREVOCABLY CONSTITUTES
AND APPOINTS THE COLLATERAL AGENT AS THE TRUE AND LAWFUL PROXY AND ATTORNEY-IN-FACT OF PLEDGOR, WITH FULL POWER OF SUBSTITUTION
IN THE PREMISES, UPON THE OCCURRENCE AND DURING THE CONTINUANCE OF AN EVENT OF DEFAULT, TO EXERCISE ALL SUCH VOTING, CONSENSUAL
AND OTHER RIGHTS AND POWERS TO WHICH ANY HOLDER OF ANY EQUITY INTERESTS WOULD BE ENTITLED BY VIRTUE OF HOLDING THE SAME, WHICH
PROXY AND POWER OF ATTORNEY, BEING COUPLED WITH AN INTEREST, IS IRREVOCABLE AND SHALL BE EFFECTIVE FOR SO LONG AS THIS AGREEMENT
SHALL BE IN EFFECT; and

 

(g)       Subject
to applicable law and regulation, to sell, resell, assign and deliver all or any of the Collateral, in one or more parcels, on
any securities exchange on which any Equity Interests may be listed, at public or private sale, at any of the Collateral Agent’s
offices or elsewhere, for cash, upon credit or for future delivery, at such time or times and at such price or prices and upon
such other terms as the Collateral Agent may deem satisfactory. If any of the Collateral is sold by the Collateral Agent upon credit
or for future delivery, the Collateral Agent shall not be liable for the failure of the purchaser to purchase or pay for the same
and, in the event of any such failure, the Collateral Agent may, but is not required to, resell such Collateral. In no event shall
Pledgor be credited with any part of the Proceeds of sale of any Collateral until and to the extent cash payment in respect thereof
has actually been received by the Collateral Agent. Each purchaser at any such sale shall hold the property sold absolutely, free
from any claim or right of whatsoever kind, including any equity or right of redemption of Pledgor, and Pledgor hereby expressly
waives, to the fullest extent permitted under applicable law, all rights of redemption, stay or appraisal, and all rights to require
the Collateral Agent to marshal any assets in favor of Pledgor or any other party or against or in payment of any or all of the
Secured Obligations, that it has or may have under any rule of law or statute now existing or hereafter adopted. No demand, presentment,
protest, advertisement or notice of any kind (except any notice required by law, as referred to below), all of which are hereby
expressly waived by Pledgor, shall be required in connection with any sale or other disposition of any part of the Collateral.
If any notice of a proposed sale or other disposition of any part of the Collateral shall be required under applicable law, the
Collateral Agent shall give the Pledgor at least ten (10) days’ prior notice of the time and place of any public sale
and of the time after which any private sale or other disposition is to be made, which notice Pledgor agrees is commercially reasonable.
The Collateral Agent shall not be obligated to make any sale of Collateral if it shall determine not to do so, regardless of the
fact that notice of sale may have been given. The Collateral Agent may, without notice or publication, adjourn any public or private
sale or cause the same to be adjourned from time to time by announcement at the time and place fixed for sale, and such sale may,
without further notice, be made at the time and place to which the same was so adjourned. Upon each public sale and, to the extent
permitted by applicable law, upon each private sale, the Collateral Agent may purchase all or any of the Collateral being sold,
free from any equity, right of redemption or other claim or demand, and may make payment therefor by endorsement and

    	 	61	 

     

    

application (without recourse) of the Secured Obligations in
lieu of cash as a credit on account of the purchase price for such Collateral. The Collateral Agent shall, to the extent required
by applicable laws, comply with any applicable state or federal law requirements in connection with the sale or other disposition
of the Collateral and Pledgor agrees that such compliance is commercially reasonable. The Collateral Agent may sell or otherwise
dispose of the Collateral without giving any warranties, specifically disclaiming any warranties of title or the like and Pledgor
agrees that such disclaimer is commercially reasonable.

 

6.2       Application
of Proceeds 

.

 

(a)       Subject
to the Intercreditor Agreements, all Proceeds collected by the Collateral Agent upon any sale, other disposition of or realization
upon any of the Collateral, together with all other moneys received by the Collateral Agent hereunder following the occurrence
and during the continuance of an Event of Default shall be applied in accordance with the Indenture.

 

(b)       Pledgor
shall remain liable to the extent of any deficiency between the amount of all Proceeds realized upon sale, other disposition or
collection of the Collateral, and monies held as Collateral pursuant to this Agreement and the aggregate amount of Secured Obligations.
Upon any sale of any Collateral hereunder by the Collateral Agent (whether by virtue of the power of sale herein granted, pursuant
to judicial proceeding, or otherwise), the receipt by the Collateral Agent or the officer making the sale shall be a sufficient
discharge to the purchaser or purchasers of the Collateral so sold, and such purchaser or purchasers shall not be obligated to
see to the application of any part of the purchase money paid over to the Collateral Agent or such officer or be answerable in
any way for the misapplication thereof.

 

6.3       Grant
of License 

. To the extent permitted by applicable law and the Intercreditor
Agreements and solely for the purpose of enabling the Secured Parties to exercise rights and remedies under this Article VI,
and at such time as the Secured Parties shall be lawfully entitled to exercise such rights and remedies, Pledgor hereby grants
to the Collateral Agent, to the extent it has the right to do so, an irrevocable, non-exclusive license (exercisable without payment
of royalty or other compensation to Pledgor), subject, in the case of Trademarks, to sufficient rights to quality control and inspection
in favor of Pledgor to avoid the risk of invalidation of such Trademarks, to use, license or sublicense any Patent Collateral,
Trademark Collateral or Copyright Collateral now owned or hereafter acquired by Pledgor, wherever the same may be located throughout
the world, for such term or terms, on such conditions and in such manner as the Collateral Agent shall determine, whether general,
special or otherwise, and whether on an exclusive or nonexclusive basis, and including in such license reasonable access to all
media in which any of the licensed items may be recorded or stored and to all computer software and programs used for the compilation
or printout thereof. The use of such license or sublicense by the Collateral Agent shall be exercised only upon the occurrence
and during the continuation of an Event of Default; provided that any license, sublicense or other transaction entered into
by the Collateral Agent in accordance herewith shall be binding upon each applicable Pledgor notwithstanding any subsequent cure
of an Event of Default.

 

6.4       Private
Sales 

.

 

(a)       Pledgor
recognizes that, by reason of certain prohibitions contained in the Securities Act and applicable state securities laws as in effect
from time to time, the Collateral Agent may be compelled, with respect to any sale of all or any part of the Equity Interests conducted
without registration or qualification under the Securities Act and such state securities laws, to limit purchasers to any one or
more persons who will represent and agree, among other things, to acquire such Equity Interests for their own account, for investment
and not with a view to the distribution or resale thereof. Pledgor acknowledges that any such private sales may be made in such
manner and under such circumstances as the Collateral Agent may deem necessary or advisable, including at prices and on terms less
favorable than those obtainable through a public sale without such restrictions (including, without limitation, a public offering
made pursuant to a registration statement under the Securities Act), and, notwithstanding such circumstances, agrees that any such
private sale shall be deemed to have been made in a commercially reasonable manner and agrees that the Collateral Agent shall have
no obligation to conduct any public sales and no obligation to delay the sale of any Equity Interests for the period of time necessary
to permit its registration for public sale under

    	 	62	 

     

    

the Securities Act and applicable state securities laws, and
shall not have any responsibility or liability as a result of its election so not to conduct any such public sales or delay the
sale of any Equity Interests, notwithstanding the possibility that a substantially higher price might be realized if the sale were
deferred until after such registration. Pledgor hereby waives any claims against the Collateral Agent or any other Secured Party
arising by reason of the fact that the price at which any Equity Interests may have been sold at any private sale was less than
the price that might have been obtained at a public sale or was less than the aggregate amount of the Secured Obligations, even
if the Collateral Agent accepts the first offer received and does not offer such Equity Interests to more than one offeree.

 

(b)       Pledgor
agrees that a breach of any of the covenants contained in this Section will cause irreparable injury to the Collateral Agent and
the other Secured Parties, that the Collateral Agent and the other 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 shall be specifically enforceable against
the Pledgor.

 

6.5       Waivers 

. Pledgor, to the greatest extent not prohibited by applicable
law, hereby (i) agrees that it will not invoke, claim or assert the benefit of any rule of law or statute now or hereafter
in effect (including, without limitation, any right to prior notice or judicial hearing in connection with the Collateral Agent’s
possession, custody or disposition of any Collateral or any appraisal, valuation, stay, extension, moratorium or redemption law),
or take or omit to take any other action, that would or could reasonably be expected to have the effect of delaying, impeding or
preventing the exercise of any rights and remedies in respect of the Collateral, the absolute sale of any of the Collateral or
the possession thereof by any purchaser at any sale thereof, and waives the benefit of all such laws and further agrees that it
will not hinder, delay or impede the execution of any power granted hereunder to the Collateral Agent, but that it will permit
the execution of every such power as though no such laws were in effect, (ii) waives all rights that it has or may have under
any rule of law or statute now existing or hereafter adopted to require the Collateral Agent to marshal any Collateral or other
assets in favor of Pledgor or any other party or against or in payment of any or all of the Secured Obligations, and (iii) waives
all rights that it has or may have under any rule of law or statute now existing or hereafter adopted to demand, presentment, protest,
advertisement or notice of any kind (except notices expressly provided for herein or in the other Security Documents) or to require
the Collateral Agent to pursue any third party for any of the Secured Obligations.

 

Article
VII

THE COLLATERAL AGENT

 

7.1       The
Collateral Agent; Standard of Care 

.

 

(a)       The
Collateral Agent will hold all items of the Collateral at any time received under this Agreement in accordance with the provisions
hereof and the Indenture. The obligations of the Collateral Agent as holder of the Collateral and interests therein and with respect
to the disposition thereof, and otherwise under this Agreement and the Indenture are only those expressly set forth in this Agreement
and the Indenture. The Collateral Agent shall act at the direction of the Trustee (acting on written direction of the appropriate
percentage of Holders under the Indenture) who shall give directions to the Collateral Agent pursuant to the Indenture. The powers
conferred on the Collateral Agent hereunder are solely to protect its interest, on behalf of the Secured Parties, in the Collateral,
and shall not impose any duty upon it to exercise any such powers. The powers conferred on the Collateral Agent hereunder are solely
to protect its interest in the Collateral, shall not impose any duty upon the Collateral Agent to exercise any such powers and
shall not make the Collateral Agent liable to any Person. Except for treatment of the Collateral in its possession in the same
manner as that which the Collateral Agent, in its individual capacity, accords its own property of a similar nature for its own
account, and the accounting for moneys actually received by it hereunder in the exercise of reasonable care, the Collateral Agent
shall have no duty as to any Collateral or as to the taking of any necessary steps to preserve rights against prior parties or
any other rights pertaining to the Collateral. Neither the Collateral Agent nor any other Secured Party shall be liable to Pledgor
(i) for any loss or damage sustained by Pledgor, or (ii) for any loss, damage, depreciation or other diminution in the
value of any of the Collateral that may occur as a result of or in connection with or that is in any way related to any exercise
by the Collateral Agent or any other Secured Party of any right or remedy under this Agreement, any failure

    	 	63	 

     

    

to demand, collect or realize upon any of the Collateral or
any delay in doing so, or any other act or failure to act on the part of the Collateral Agent or any other Secured Party, except
to the extent that the same is caused by its own gross negligence or willful misconduct.

 

(b)       The
Collateral Agent shall not be responsible for and makes no representation as to the existence, genuineness, value or protection
of any Collateral, for the legality, effectiveness or sufficiency of any Security Document, or for the creation, perfection, priority,
sufficiency or protection of any Liens securing the Secured Obligations. For the avoidance of doubt, nothing herein shall require
the Collateral Agent to file financing statements, continuation statements or termination statements, or be responsible for maintaining
the security interests purported to be created as described herein (except for the safe custody of any Collateral in its possession
and the accounting for moneys actually received by it hereunder or under any other Security Document) and such responsibility shall
be solely that of the Pledgor. In connection with its execution and acting under this Agreement, the Collateral Agent is entitled
to all rights, privileges, protections, immunities, benefits and indemnities provided to it under the other Security Documents,
all of which are incorporated by reference herein mutatis mutandis. Notwithstanding anything to the contrary herein, express
or implied, the Collateral Agent shall have no duty to take any discretionary action or exercise any discretionary powers (including
making any determination or deeming any matter appropriate, necessary or satisfactory) unless it first receives written direction
from the Trustee acting on behalf of the appropriate percentage of Holders under the Indenture. Furthermore, if the Collateral
Agent shall not have received appropriate instruction within 10 days of a request therefor from the Trustee (or such shorter period
as reasonably may be specified in such notice or as may be necessary under the circumstances) it may, but shall be under no duty
to, take or refrain from taking such action as it shall deem to be in the best interests of the itself and the Trustee and the
Collateral Agent shall have no liability to any Person for such action or inaction.

 

(c)       Notwithstanding
anything to the contrary herein, whenever reference is made in this Agreement to any action by, consent, designation, specification,
requirement or approval of, notice, request or other communication from, or other direction given or action to be undertaken or
to be (or not to be) suffered or omitted by the Collateral Agent, to any amendment, waiver or other modification of this Agreement
to be executed (or not to be executed) by the Collateral Agent or to any election, decision, opinion, acceptance, use of judgment,
expression of satisfaction or other exercise of discretion, rights or remedies to be made (or not to be made) by the Collateral
Agent, it is understood that in all cases the Collateral Agent shall be acting, giving, withholding, suffering, omitting, making
or otherwise undertaking and exercising the same (or shall not be undertaking and exercising the same) as directed in accordance
with the written direction of the Trustee acting upon the written direction of the appropriate percentage of Holders under the
Indenture, as applicable. This provision is intended solely for the benefit of the Collateral Agent and its successors and permitted
assigns and is not intended to and will not entitle the other parties hereto to any defense, claim or counterclaim under or in
relation to any Security Document, or confer any rights or benefits on any party hereto.

 

7.2       Further
Assurances; Attorney-in-Fact 

.

 

(a)       Pledgor
hereby authorizes the Collateral Agent to sign (to the extent the Pledgor’s signature is required thereon) financing statements
and amendments thereto relating to all or any part of the Collateral without the signature of Pledgor (including, without limitation,
making any notice filings with state tax or revenue authorities required to be made by account creditors in order to enforce any
Accounts in such state); provided that, promptly following the filing thereof, the Pledgor shall provide the Collateral
Agent with a copy of any initial financing statement filed by it or any amendment to any initial financing statement which changes
the collateral description set forth therein. The Pledgor further agrees to execute and deliver to the Collateral Agent such additional
conveyances, assignments, agreements and instruments as the Collateral Agent may reasonably require under applicable law to perfect,
establish, confirm and maintain the security interest and Lien provided for herein, to carry out the purposes of this Agreement
or to further assure and confirm unto the Collateral Agent its rights, powers and remedies hereunder.

 

(b)       Pledgor
hereby irrevocably appoints the Collateral Agent its lawful attorney-in-fact, with full authority in the place and stead of Pledgor
and in the name of Pledgor, the Collateral Agent or otherwise, and with full power of substitution in the premises (which power
of attorney, being coupled with an interest, is irrevocable for so long as this Agreement shall be in effect), from time to time,
after the occurrence and during the continuance of

    	 	64	 

     

    

an Event of Default (except for the actions described in clauses (ii),
(iv) and (vii) below which may be taken by the Collateral Agent without regard to whether an Event of Default has occurred)
to take any action and to execute any instruments that are necessary or advisable to accomplish the purpose of this Agreement,
including, without limitation:

 

(i) to ask, demand, collect, sue

MISCELLANEOUS

 

8.1       Indemnity
and Expenses

(a)       to
indemnify and hold harmless the Collateral Agent, the Trustee, each other Secured Party and each of their respective directors,
officers, employees, agents and affiliates from and against any and all claims, damages, demands, losses, obligations, judgments
and liabilities (including, without limitation, reasonable attorneys’ fees, out of pocket costs and expenses) in any way
arising out of or in connection with this Agreement, except to the extent the same shall arise as a result of the gross negligence
or willful misconduct of the party seeking to be indemnified; and

 

(b)       to
pay and reimburse the Collateral Agent and the Trustee upon demand for all reasonable costs and expenses (including, without limitation,
reasonable attorneys’ fees, out of pocket costs and expenses) that the Collateral Agent may incur in connection with (i) the
custody, use or preservation of, or the sale of, collection from or other realization upon, any of the Collateral, including the
reasonable expenses of retaking, holding, preparing for sale or lease, selling or otherwise disposing of or realizing on the Collateral,
(ii) the exercise or

    	 	65

at law, in equity or otherwise), or (iii) the failure by Pledgor to perform or observe any of the provisions hereof. The provisions
of this Section shall survive the execution and delivery of this Agreement, the repayment of any of the Secured Obligations and
the discharge of the Indenture.

 

8.2       No
Waiver 

. The rights and remedies of the Secured Parties expressly set
forth in this Agreement, the Indenture, the Guarantee and the Notes are cumulative and in addition, to, and not exclusive of, all

any right, power or privilege shall operate as a waiver thereof, nor shall any single or partial exercise of any such right, power

or employees shall be effective to amend, modify or discharge any provision of this Agreement of the Guarantee or the Indenture
or Notes or to constitute a waiver of any Default or Event of Default. No notice to or demand upon Pledgor in any case shall entitle
Pledgor to any other or further notice or demand in similar or other circumstances or constitute a waiver of the right of any Secured
Party to exercise any right or remedy or take any other or further action in any circumstances without notice or demand.

 

8.3       Pledgor’s
Obligations Absolute 

. Until such time as this Agreement terminates pursuant to Section 8.6,

or otherwise) any right or remedy in respect of any Secured Obligations or any Collateral or other security therefor, or any failure
to create, protect, perfect, secure, insure, continue or maintain any Liens in any such Collateral or other security;

or remedy available under the Indenture, the Notes or other Security Document, at law, in equity or otherwise in respect of any

(ix) any other circumstance that
might otherwise constitute a legal or equitable discharge of, or a defense, set-off or counterclaim available to, the Issuer, Pledgor
or a surety or guarantor generally, other

    	 	66

	2.	Subordination. 

 

2.1 Subordination of Subordinated
Debt to Senior Debt. The Issuer agrees, and the Trustee agrees on behalf of each Holder, that the Indebtedness evidenced
by the Notes is subordinated in right of payment, to the extent and in the manner provided in this Article 2, to the prior payment
in full of all Issuer Senior Debt (whether outstanding on the date hereof or hereafter created, incurred, assumed or guaranteed),
and that the subordination is for the benefit of and enforceable by holders of Issuer Senior Debt. The Indebtedness evidenced by
the Notes shall in all respects rank pari passu in right of payment with all existing and future unsubordinated Indebtedness
of the Issuer (other than Issuer Senior Debt) and will be senior in right of payment to all existing and future subordinated Indebtedness
of the Issuer; and only Indebtedness that is Issuer Senior Debt shall rank senior to the Indebtedness evidenced by the Notes in
accordance with the provisions set forth herein. All provisions of this Article 2 shall be subject to Section 2.11
hereof.

 

2.2 Liquidation, Dissolution, Bankruptcy.
Upon any payment or distribution of the assets of the Issuer to creditors upon a total or partial liquidation or a total or partial
dissolution of the Issuer or in a bankruptcy, reorganization, insolvency, receivership of or similar proceeding relating to the
Issuer or its property, in an assignment for the benefit of creditors or in any marshaling of the Issuer’s assets and liabilities:

 

(a) holders of Issuer Senior Debt
shall be entitled to receive payment in full in cash of such Issuer Senior Debt (including interest accruing after, or which would
accrue but for, the commencement of any such proceeding at the rate specified in the applicable Issuer Senior Debt, whether or
not a claim for such interest would be allowed) before the Holders of Notes shall be entitled to receive any payment with respect
to the Notes; and

 

(b) until all Obligations with respect to
the Issuer Senior Debt (as provided in clause (a) above) are paid in full in cash, any payment or distribution to which
Holders of Notes would be entitled but for this Article 2 shall be made to holders of Issuer Senior Debt as their interests
may appear.

 

2.3 Default on Issuer Senior Debt.

 

(a) The Issuer may not make any
payment or distribution to the Trustee or any Holder in respect of Obligations with respect to the Notes and may not acquire from
the Trustee or any Holder any Notes for cash or property until all principal and other Obligations with respect to the Issuer Senior
Debt have been paid in full if:

 

(i) a payment default on Issuer Senior Debt
occurs and is continuing; or

 

(ii) any other default occurs and is continuing on any Issuer
Senior Debt that permits the holders of such Issuer Senior Debt to accelerate its maturity, or otherwise demand its
payment, and the Trustee receives a notice of such default (a “Notes Payment Blockage Notice”) from the
Issuer or the holders of such Issuer Senior Debt.

 

(b) The Issuer may and will resume payments or any distributions
in respect of the Notes and may acquire them upon the earlier of:

 

(i) in the case of a payment default with respect to
any Issuer Senior Debt, the date upon which such default is cured or waived, and

 

(ii) in the case of a nonpayment
default with respect to any Issuer Senior Debt, upon the earlier of the date on which such nonpayment default is cured or waived
and 179 days after the date on which the applicable Notes Payment Blockage Notice is received, unless in the case of this clause
(ii), the maturity of any Issuer Senior Debt has been accelerated or demand for payment of such Issuer Senior Debt made, and such
acceleration or demand for payment has not been waived or cancelled, if this Article 2 otherwise permits such payment, distribution
or acquisition at the time of such payment, distribution or acquisition.

 

     

     

    

  

2.4 Demand for Payment. If
payment of the Notes is accelerated because of an Event of Default, the Issuer or the Trustee will promptly notify holders of the
Issuer Senior Debt, of the acceleration; provided that any failure to give such notice shall have no effect whatsoever on the provisions
of this Article 2. If any Issuer Senior Debt is outstanding, the Issuer may not make a payment of the Notes until ten (10) Business
Days after holders of such Issuer Senior Debt receive notice of such acceleration and, thereafter, may make a payment of any Obligations
with respect to the Notes only if this Agreement, the Indenture and federal law otherwise permits payment at that time.

 

2.5 When Distribution Must be Paid
Over. In the event that the Trustee or any Holder of the Notes receives any payment of, or any distributions with respect
to, any Obligations with respect to the Notes at a time when the payment is prohibited by Section 2.3 hereof and the
Trustee or the Holder, as applicable, has actual knowledge that the payment is prohibited by Section 2.3 hereof, such
payment will be held by the Trustee or such Holder, in trust for the benefit of, and will be paid forthwith over and delivered
upon written request to, holders of Issuer Senior Debt as their interests may appear under the agreement, indenture or other document
(if any) pursuant to which any Issuer Senior Debt may have been issued or incurred, for application to the payment of all Obligations
with respect to Issuer Senior Debt remaining unpaid to the extent necessary to pay such Obligations in full in accordance with
their terms, after giving effect to any concurrent payment or distribution to or for the holders of Issuer Senior Debt.

 

2.6 Subrogation. After all
Issuer Senior Debt is Discharged and until the Notes are paid in full, Holders of Notes will be subrogated to the rights of the
holders of Issuer Senior Debt to receive distributions applicable to such Issuer Senior Debt to the extent that distributions otherwise
payable to the Holders of Notes have been applied to the payment of such Issuer Senior Debt. A distribution made under this Article
2 to the holders of Issuer Senior Debt that otherwise would have been made to Holders of Notes is not, as between the Issuer and
Holders, a payment by the Issuer on the Notes.

 

2.7 Relative Rights. This
Article 2 defines the relative rights of Holders of Notes and holders of Issuer Senior Debt. Nothing in this Agreement will:

 

(a) impair, as between the Issuer
and Holders of Notes, the obligation of the Issuer, which is absolute and unconditional, to pay principal of, premium, if any,
on, and interest, if any, on, the Notes in accordance with their terms;

 

(b) affect the relative rights
of Holders of Notes and creditors of the Issuer other than their rights in relation to holders of Issuer Senior Debt; or

 

(c) prevent the Trustee or any
Holder of Notes from exercising its available remedies upon a Default or Event of Default, subject to the rights of holders of
Issuer Senior Debt to receive distributions and payments otherwise payable to Holders of Notes and such other rights of holders
of Issuer Senior Debt as set forth herein.

 

2.8 Subordination May Not Be Impaired
by the Issuer. No right of the holders of Issuer Senior Debt to enforce the subordination of the Indebtedness evidenced
by the Notes may be impaired by any act or failure to act by the Issuer or any Holder or by the failure of the Issuer or any Holder
to comply with the Indenture or this Agreement.

 

2.9 Rights of Trustee and Paying Agent.

 

(a) Notwithstanding the provisions
of this Article 2 or any provision of the Indenture, the Trustee will not be charged with knowledge of the existence of any facts
that would prohibit the making of any payment or distribution by the Trustee, and the Trustee and the Paying Agent may continue
to make payments on the Notes, unless the Trustee has received at its Corporate Trust Office at least three (3) Business Days
prior to the date of such payment written notice of facts that would cause the payment of any Obligations with respect to the Notes
to violate this Article 2. Only the Issuer or holders of Issuer Senior Debt may give the notice. Nothing in this Article 2 will
impair the claims of, or payments to, the Trustee under or pursuant to Section 7.07 of the Indenture.

 

     

     

    

  

(b) The Trustee shall have no
responsibility or obligation to any beneficial owner of a Global Note, a member of, or a participant in, DTC or other Person with
respect to the accuracy of the records of DTC or its nominee or of any participant or member thereof, with respect to any ownership
interest in the Notes or with respect to the delivery to any participant, member, beneficial owner or other Person (other than
DTC) of any notice (including any notice of redemption or purchase) or the payment of any amount or delivery of any Notes (or other
security or property) under or with respect to such Notes.

 

All notices and communications to be given
to the Holders and all payments to be made to Holders in respect of the Notes shall be given or made only to the registered Holders
(which shall be DTC or its nominee in the case of a Global Note). The rights of beneficial owners in any Global Note shall be exercised
only through DTC subject to the applicable rules and procedures of DTC. The Trustee may rely and shall be fully protected in relying
upon information furnished by DTC with respect to its members, participants and any beneficial owners.

 

The Trustee shall have no obligation or
duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under the Indenture or under applicable
law with respect to any transfer of any interest in any Note (including any transfers between or among DTC participants, members
or beneficial owners in any Global Note) other 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 the Indenture, and to examine the same
to determine substantial compliance as to form with the express requirements hereof.

 

2.10 Article 2 Not to Prevent Events
of Default or Limit Right to Demand Payment. The failure of the Issuer to make a payment on the Notes by reason of any
provision in this Article 2 shall not be construed as preventing the occurrence of a Default by the Issuer. Nothing in this Article
2 shall have any effect on the right of the Holders or the Trustee to make a demand for payment on the Notes pursuant to Article
2 of the Indenture.

 

2.11 Trust Moneys Not Subordinated.
Notwithstanding anything contained herein to the contrary, payments from money or the proceeds of Government Securities held in
trust by the Trustee for the payment of principal of and interest on the Notes pursuant to Article 8 or Article 12 of the Indenture
shall not be subordinated to the prior payment of any Issuer Senior Debt or subject to the restrictions set forth in this Article
2, and none of the Holders shall be obligated to pay over any such amount to the Issuer or holders of Issuer Senior Debt or any
other creditor of the Issuer, provided that, the subordination provisions of this Article 2 were not violated at the time the applicable
amounts were deposited in trust pursuant to Article 8 or Article 12 of the Indenture, as the case may be.

 

2.12 Trustee Entitled to Rely.
Upon any payment or distribution of assets of the Issuer referred to in this Article 2, the Trustee and the Holders of Notes will
be entitled to rely upon any order or decree of a court of competent jurisdiction in which any proceedings of the nature referred
to in Section 2.12 hereof are pending or upon any certificate of such representative or of the liquidating trustee
or agent or other Person making any distribution to the Trustee or to the Holders of Notes for the purpose of ascertaining the
Persons entitled to participate in such payment or distribution, the holders of Issuer Senior Debt and other Indebtedness of the
Issuer, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent
thereto or to this Article 2. In the event that the Trustee determines, in good faith, that evidence is required with respect to
the right of the holders of Issuer Senior Debt to participate in any payment or distribution pursuant to this Article 2, the Trustee
shall be entitled to request such Person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of
such Issuer Senior Debt held by such Person, the extent to which such Person is entitled to participate in such payment or distribution
and other facts pertinent to the rights of such Person under this Article 2 and, if such evidence is not furnished, the Trustee
shall be entitled to defer any payment to such Person pending judicial determination as to the right of such Person to receive
such payment. The provisions of Section 7.01 and Section 7.02 of the Indenture shall be applicable to all
actions or omissions of actions by the Trustee pursuant to this Article 2.

 

2.13 Trustee to Effectuate Subordination.
This Agreement is intended to effectuate the subordination provided in Article 2 of the Indenture as contemplated by Section 2.27
of the Indenture.

 

     

     

    

  

2.14 Trustee Not Fiduciary for Holders
of Issuer Senior Debt. The Trustee shall not be deemed to owe any fiduciary duty to the holders of Issuer Senior Debt and
shall not be liable to any such holder if it shall mistakenly pay over or distribute to or on behalf of Holders or any other Person,
money or assets to which holders of Issuer Senior Debt shall be entitled by virtue of this Article 2 or otherwise, except if such
payment is made as a result of the willful misconduct or gross negligence of the Trustee.

 

2.15 Reliance by Holders of Senior
Debt on Subordinated Provisions. Each Holder pursuant to the Indenture and by accepting a Note, has acknowledged and agreed
that provisions comparable to those in this Article 2 hereof are, and are intended to be, an inducement and a consideration to
holders of Issuer Senior Debt, whether such Issuer Senior Debt was created or acquired before or after the issuance of the Notes,
to acquire and continue to hold, or to continue to hold, such Issuer Senior Debt and holders of such Issuer Senior Debt shall be
deemed conclusively to have relied on such subordination provisions in acquiring and continuing to hold, or in continuing to hold,
such Issuer Senior Debt.

 

Without in any way limiting the generality
of the foregoing paragraph, holders of Issuer Senior Debt may, at any time and from time to time, without the consent of or notice
to the Trustee or the Holders, without incurring liability to the Trustee or the Holders and without impairing or releasing the
subordination provided in this Article 2 or the obligations hereunder of the Holders to holders of Issuer Senior Debt, do any
one or more of the following: (i) change the manner, place or terms of payment or extend the time of payment of, or renew
or alter, any Issuer Senior Debt, or otherwise amend or supplement in any manner any Issuer Senior Debt, or any instrument evidencing
the same or any agreement under which any Issuer Senior Debt is outstanding; (ii) sell, exchange, release or otherwise deal
with any property pledged, mortgaged or otherwise securing any Issuer Senior Debt; (iii) release any Person liable in any
manner for the payment or collection of any Issuer Senior Debt; and (iv) exercise or refrain from exercising any rights against
the Issuer and any other Person.

 

	3.	Miscellaneous

 

3.1 Integration/Conflicts. This
Agreement and the Indenture represent the entire agreement with respect to the subject matter hereof and thereof, and supersede
any and all previous agreements and understandings, oral or written, relating to the subject matter hereof and thereof. There are
no promises, undertakings, representations or warranties by the Trustee or the Holders relative to the subject matter hereof and
thereof not expressly set forth or referred to herein or therein. In the event of any conflict between the provisions of this Agreement
and the provisions of the Indenture, the provisions of this Agreement shall govern and control.

 

3.2 Effectiveness; Continuing Nature
of this Agreement; Severability. This Agreement shall become effective when executed and delivered by the parties hereto.
This is a continuing agreement of payment subordination and the Issuer Senior Debt Claimholders may continue, at any time and without
notice to the Trustee or any Holder, to extend credit and other financial accommodations and lend monies to or for the benefit
of the Issuer constituting Issuer Senior Debt in reliance hereon. The terms of this Agreement shall survive, and shall continue
in full force and effect, in any filing or proceeding under the Bankruptcy Code. Any provision of this Agreement that 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. The parties hereto shall endeavor in good-faith negotiations
to replace any invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as
possible to those of the invalid, illegal or unenforceable provisions. All references to the Issuer shall include the Issuer as
debtor and debtor-in-possession and any receiver, trustee or similar person acting for the Issuer (as the case may be) in any proceeding
under the Bankruptcy Code. This Agreement shall terminate and be of no further force and effect:

 

(a) with respect to any Issuer
Senior Debt Representative and the Issuer Senior Debt Claimholders represented by it and their Issuer Senior Debt Obligations,
on the date on which the Issuer Senior Debt Obligations of such Issuer Senior Debt Claimholders are Discharged subject to the rights
of such Issuer Senior Debt Claimholders under Section 3.20 and Section 3.21; and

 

     

     

    

  

(b) with respect to the Trustee
and the Holders on the date that all Issuer Senior Debt has been Discharged subject to the rights of such Issuer Senior Debt Claimholders
under Section 3.20 and Section 3.21;

 

provided, however, that in each case, such termination
shall not relieve any such party of its obligations incurred hereunder prior to the date of such termination.

 

3.3 Amendments; Waivers

 

(a) No amendment, modification
or waiver of any of the provisions of this Agreement shall be deemed to be made unless the same shall be in writing signed on behalf
of each party hereto or its authorized agent and each waiver, if any, shall be a waiver only with respect to the specific instance
involved and shall in no way impair the rights of the parties making such waiver or the obligations of the other parties to such
party in any other respect or at any other time. Notwithstanding the foregoing, the Issuer shall not have any right to consent
to or approve any amendment, modification or waiver of any provision of this Agreement except to the extent its rights are directly
and adversely affected.

 

(b) Notwithstanding the foregoing,
without the consent of the Issuer or any party hereto any Person holding Issuer Senior Debt or their agent, trustee or representative
may become a party hereto by execution and delivery of a Joinder Agreement in accordance with Section 3.7 of this Agreement
and upon such execution and delivery, such Additional Issuer Senior Representative and the Additional Issuer Senior Debt Claimholders
represented thereby shall be subject to the terms hereof.

 

3.4 Information Concerning Financial
Condition of the Issuer and its Subsidiaries. The Issuer Senior Debt Representatives and the Issuer Senior Debt Claimholders,
on the one hand, and the Holders, on the other hand, shall each be responsible for keeping themselves informed of (a) the
financial condition of the Issuer, its Subsidiaries and any endorsers and guarantors of the Issuer Senior Debt Obligations or the
Notes and (b) all other circumstances bearing upon the risk of nonpayment of the Issuer Senior Debt Obligations or the Notes.
The Issuer Senior Debt Representatives and the other Issuer Senior Debt Claimholders, on the one hand, and the Holders, on the
other hand, shall have no duty to advise of information known to it or them regarding such condition or any such circumstances
or otherwise. In the event any Claimholder, in its sole discretion, undertakes at any time or from time to time to provide any
such information to any other Claimholder, it shall be under no obligation:

 

(a) to make, and such Claimholder
shall not make, any express or implied representation or warranty, including with respect to the accuracy, completeness, truthfulness
or validity of any such information so provided;

 

(b) to provide any additional
information or to provide any such information on any subsequent occasion;

 

(c) to undertake any investigation;
or

 

(d) to disclose any information,
which pursuant to accepted or reasonable commercial finance practices, such party wishes to maintain confidential or is otherwise
required to maintain confidential.

 

3.5 Subrogation. With respect
to the value of any payments or distributions in cash, property or other assets that any of the Trustee or the Holders pays over
to any of the Issuer Senior Debt Representatives or the other Issuer Senior Debt Claimholders under the terms of this Agreement,
the Trustee or such Holders shall be subrogated to the rights of such Issuer Senior Debt Representatives or the other Issuer Senior
Debt Claimholders; provided that the Trustee, on behalf of itself and each Holder, hereby agrees not to assert or enforce any
such rights of subrogation it may acquire as a result of any payment hereunder until the Discharge of all Issuer Senior Debt has
occurred. The Company acknowledges and agrees that the value of any payments or distributions in cash, property or other assets
received by the Trustee or any Holder that are paid over to any Issuer Senior Debt Representatives or the other Issuer Senior
Debt Claimholders pursuant to this Agreement shall not reduce any of the obligations under the Indenture. 

 

3.6 Application of Payments.
All payments received by any Issuer Senior Debt Representative or other Issuer Senior Debt Claimholder may be applied, reversed
and reapplied, in whole or in part, to such part of the Issuer Senior Debt Obligations provided for in the applicable Issuer Senior
Debt or the documents evidencing or governing such Issuer Senior Debt (subject to any agreement among the Issuer Senior Debt Representatives).
The Trustee, on behalf of itself and each Holder, agrees to any extension or postponement of the time of payment of the Issuer
Senior Debt Obligations or any part thereof and to any other indulgence with respect thereto, to any substitution, exchange or
release of any payment which may at any time secure any part of the Issuer Senior Debt Obligations and to the addition or release
of any other Person primarily or secondarily liable therefor.

 

     

     

    

  

3.7 Additional Issuer Senior Debt
Claims. Any Person holding Issuer Senior Debt or their agent, trustee or representative may, but is not obligated to, become
a party hereto by execution and delivery of a joinder agreement in substantially the form of Exhibit A hereto.

 

3.8 Agency Capacities. The
Company is acting in the capacity of Initial Issuer Senior Debt Representative solely for the Initial Issuer Senior Debt Claimholders.
Each other Issuer Senior Debt Representative is acting in the capacity of Issuer Senior Debt Representative solely for the Issuer
Senior Debt Claimholders for which it has been appointed agent, trustee or other representative. The Trustee is acting as Trustee
solely for the Holders.

applicable Claimholder represented by it, hereby irrevocably and unconditionally:

(d) waives, to the fullest extent
permitted by applicable law, any objection that it may now or hereafter have to the laying of venue of any action or proceeding

such action or proceeding in any such court);

 

(e) consents to service of process
in any such proceeding in any such court by registered or certified mail, return receipt requested, to the applicable party at
its address provided in accordance with Section 3.11 (and agrees that nothing in this Agreement will affect the right
of any party hereto to serve process in any other manner permitted by applicable law);

3.18 Third Party Beneficiaries/ Provisions

Deemed to Not Have Occurred. If contemporaneously with the Discharge of Issuer Senior Debt, the Company enters into any
Refinancing of such Issuer Senior Debt, then such Discharge of Issuer Senior Debt shall automatically be deemed not to have occurred
for all purposes of this Agreement and the obligations under such Refinancing of the applicable Issuer Senior Debt shall automatically
be treated as Issuer Senior Debt for all purposes of this Agreement.

 

3.21 Avoidance Issues. If
any Issuer Senior Debt Claimholder is required as a result of any filing or proceeding under the Bankruptcy Code or otherwise to
turn over or otherwise pay to the estate of the Issuer any amount paid in respect of Issuer Senior Debt Obligations (a “Recovery”),
then such Issuer Senior Debt Claimholder shall be entitled to a reinstatement of its Issuer Senior Debt Obligations with respect
to all such recovered amounts on the date of such Recovery, and from and after the date of such reinstatement the Discharge of
Issuer Senior Debt Obligations shall be deemed not to have occurred for all purposes hereunder. If this Agreement shall have been
terminated prior to such Recovery, this Agreement shall be reinstated in full force and effect, and such prior termination shall
not diminish, release, discharge, impair or otherwise affect the obligations of the parties hereto from such date of reinstatement.
