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.

(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.


 


(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.


 


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.

(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.


 


ARTICLE
III

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.


 


ARTICLE
IV

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.

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 unless the same shall be permitted by Section 5.02(b),
and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. No notice
or demand on any party hereto in any case shall entitle such party to any other or further notice or demand in similar or other
circumstances.


 


(b)              
Neither this Agreement nor any provision hereof may be terminated,
waived, amended or modified (other than pursuant to any Joinder Agreement) except pursuant to an agreement or agreements in writing
entered into by each Authorized Representative and each Collateral Agent (and with respect to any such termination, waiver, amendment
or modification which by the terms of this Agreement requires the Grantor’s consent or which increases the obligations or
reduces the rights of the Grantor, with the consent of the Grantor).


 


(c)               
Notwithstanding the foregoing, without the consent of any Pari
Passu-Lien Secured Party, any Authorized Representative may become a party hereto by execution and delivery of a Joinder Agreement
in accordance with Section 2.08 and upon such execution and delivery, such Authorized Representative and the Pari Passu-Lien
Secured Parties and Pari Passu-Lien Obligations of the Series for which such Authorized Representative is acting shall be subject
to the terms hereof and the terms of the Pari Passu-Lien Security Documents applicable thereto.


 


(d)              
Notwithstanding the foregoing, in connection with any Refinancing
of Pari Passu-Lien Obligations of any Series, the Collateral Agents and the Authorized Representatives then party hereto
shall enter (and are hereby authorized to enter without the consent of any other Pari Passu-Lien Secured Party or the Grantor),
at the request of any Collateral Agent, any Authorized Representative or the Issuer, into such amendments or modifications of
this Agreement as are reasonably necessary to reflect such Refinancing and are reasonably satisfactory to each such Collateral
Agent and each such Authorized Representative, provided that any Collateral Agent or Authorized Representative may condition

jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. The parties shall endeavor
in good faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect
of which comes as close as possible to that of the invalid, illegal or unenforceable provisions.

[FORM
OF] JOINDER NO. [      ] dated as of [________], 20[  ] to the PARI PASSU LIEN INTERCREDITOR
AGREEMENT dated as of February 14, 2017 (the “Pari Passu Intercreditor Agreement”), among United
States Enrichment Corporation, a Delaware limited corporation (the “Grantor”), DELAWARE TRUST COMPANY,
as Existing Notes Collateral Agent and Existing Notes Authorized Representative for the Existing Notes Secured Parties under the
Existing Notes Security Documents, DELAWARE TRUST COMPANY, as New Notes Collateral Agent and New Notes Authorized Representative
for the New Notes Secured Parties under the New Notes Security Documents.


 


A.       Capitalized
terms used herein but not otherwise defined herein shall have the meanings assigned to such terms in the Pari Passu Intercreditor
Agreement.


 


B.       As
a condition to the ability of the Issuer to Refinance the Pari Passu-Lien Obligations (such obligations the “Refinanced
Pari Passu-Lien Obligations”), the authorized representative in respect of such Refinanced Pari Passu-Lien Obligations is
required to become an Authorized Representative (the “New Representative”), the collateral agent in respect
of such Refinanced Pari Passu-Lien Obligations is required to become a Collateral Agent (the “New Collateral Agent”),
and such Refinanced Pari Passu-Lien Obligations and the secured parties in respect thereof are required to become subject to and
bound by, the Pari Passu Intercreditor Agreement.


 


Accordingly,
each Collateral Agent, each Authorized Representative, the New Representative and the New Collateral Agent agree as follows:


 


SECTION
1.In accordance with Section 2.08 of the Pari Passu Intercreditor Agreement, the New Representative by its signature below
becomes an Authorized Representative under, the New Collateral Agent by its signature below becomes a Collateral Agent under,
and the related Refinanced Pari Passu-Lien Obligations and Pari Passu-Lien Secured Parties become subject to and bound by, the
Pari Passu Intercreditor Agreement with the same force and effect as if the New Representative had originally been named therein
as an Authorized Representative and the New Collateral Agent had originally been named therein as a Collateral Agent, and each
of the New Representative and the New Collateral Agent, on its behalf and on behalf of such Pari Passu-Lien Secured Parties, hereby
agrees to all the terms and provisions of the Pari Passu Intercreditor Agreement applicable to it as Authorized Representative
or Collateral Agent, as applicable, and to the Pari Passu-Lien Secured Parties that it represents. Each reference to an “Authorized
Representative” in the Pari Passu Intercreditor Agreement shall be deemed to include the New Representative. Each reference
to a “Collateral Agent” in the Pari Passu Intercreditor Agreement shall be deemed to include the New Collateral Agent.
The Pari Passu Intercreditor Agreement is hereby incorporated herein by reference.


 


SECTION
2.Each of the New Representative and the New Collateral Agent represents and warrants to each Collateral Agent, each Authorized
Representative and the other Pari Passu-Lien Secured Parties, individually, that (i) it has full power and authority to enter
