created, incurred, assumed or guaranteed, shall be deemed to have acquired Senior Debt in reliance upon the provisions contained
in this Agreement.

Dissolution, Bankruptcy. In the event of any Proceeding involving any Credit Party:


 


(a)All
Senior Debt shall first be Paid in Full before any Distribution, whether in cash, securities or other property, shall be made
to Subordinated Agent or any Subordinated Creditor on account of any Subordinated Debt.


 


(b)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 Subordinated Debt shall be paid or delivered directly to Agent (to be held and/or applied to the Senior Note
Debt by Agent in accordance with the terms of the Senior Note Debt Documents) until all Senior Note Debt is Paid in Full (upon
such event Agent shall deliver to Senior L/C Lender (or to such other Person entitled thereto under applicable law) amounts and
any cash, securities or other property held and not applied to the Senior Note Debt), and thereafter to Senior L/C Lender (to
be held and/or applied to the Senior L/C Debt by Senior L/C Lender in accordance with the terms of the Senior L/C Debt Documents)
until all Senior L/C Debt is Paid in Full. The Subordinated Agent, on behalf of itself and each Subordinated Creditor, 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 to Agent (to be held and/or applied to the Senior

(to be held and/or applied to the Senior L/C Debt by Senior L/C Lender in accordance with the terms of the Senior L/C Debt Documents)
until all Senior L/C Debt is Paid in Full. The Subordinated Agent, on behalf of itself and each Subordinated Creditor, also irrevocably
authorizes and empowers Agent until all Senior Note Debt is Paid in Full, and thereafter Senior L/C Lender until all Senior L/C
Debt is Paid in Full, in the name of Subordinated Agent, on behalf of itself and each Subordinated Creditor, to demand, sue for,
collect and receive any and all such Distributions.

any claim, action or other proceeding challenging the enforceability, validity, perfection or priority of the Senior Debt or any
liens and security interests securing the Senior Debt, (ii) not to, directly or indirectly, provide, offer to provide, or support
any financing (other than any DIP Financing provided by the Senior Note Lenders) provided under Section 364 of the Bankruptcy
Code or any similar provision of any other Bankruptcy Law (such financing, a “DIP Financing”), without the written
consent of the Senior Lenders, (iii) not to object to any DIP Financing provided by any Senior Note Lender and (iv) to consent

Agent, on behalf of itself and each Subordinated Creditor, agrees to execute, verify, deliver and file any proofs of claim in
respect of the Subordinated Debt requested by Agent until all Senior Note Debt is Paid in Full, and thereafter by Senior L/C Lender
until all Senior L/C Debt is Paid in Full in connection with any such Proceeding and hereby irrevocably authorizes, empowers and
appoints Agent until all Senior Note Debt is Paid in Full, and thereafter Senior L/C Lender until all Senior L/C Debt is Paid
in Full, its agent and attorney-in-fact with full power of substitution and with full authority in the place and stead of Subordinated
Agent and each Subordinated Creditor and in the name of Subordinated Agent and each Subordinated Creditor or otherwise to (i)
execute, verify, deliver and file such proofs of claim upon the failure of Subordinated Agent or the Subordinated Creditors promptly
to do so prior to 10 days before the expiration of the time to file any such proof of claim and (ii) vote such claim in any such
Proceeding upon the failure of Subordinated Agent or Subordinated Creditors to do so prior to 10 days before the expiration of
the time to vote any such claim; provided neither Agent nor Senior L/C Lender shall have any obligation to execute, verify, deliver,
file and/or vote any such proof of claim. In the event that Agent or Senior L/C Lender, as applicable, votes any claim in accordance
with the authority granted hereby, Subordinated Agent and each Subordinated Creditor shall not be entitled to change or withdraw
such vote.


 


(e)The
Senior Debt shall continue to be treated as Senior Debt and the provisions of this Agreement shall continue to govern the relative
rights and priorities of Senior Lenders, Subordinated Agent and Subordinated Creditors even if all or part of the Senior Debt
or the security interests securing the Senior Note Debt and/or any security interests securing the Senior L/C Debt are subordinated,
set aside, avoided, invalidated or disallowed in connection with any such Proceeding, and this Agreement shall be reinstated if
at any time any payment of any of the Senior Debt is rescinded or must otherwise be or is returned by any holder of Senior Debt
or any representative of such holder.


 


2.3.Subordinated
Debt Payment Restrictions.


 


(a)Notwithstanding
the terms of the Subordinated Debt Documents, each Credit Party hereby agrees that it may not make, and the Subordinated Agent,
on behalf of itself and each Subordinated Creditor, hereby agrees that it will not accept, any Distribution with respect to the
Subordinated Debt until all of the Senior Debt is Paid in Full; provided, that, (i) so long as no Senior Default has occurred
and is continuing or would result therefrom, the Credit Parties may make, and the Subordinated Agent may accept, cash interest
payments in accordance with Section 2 of the Subordinated Notes (as in effect on the date hereof) and (ii) nothing in this Agreement
shall prohibit issuances of common stock of the Borrower in accordance with the provisions of (A) the Subordinated Notes (as in
effect on the date hereof) and (B) the Subordinated Warrants (as in effect on the date hereof) (such Distributions described in
clauses (i) and (ii) above, the “Permitted Subordinated Debt Payments”).

shall have received a written waiver from Agent and/or Senior L/C Lender, as applicable.

by Subordinated Agent under this Agreement is made and received by Subordinated Agent or any Subordinated Creditor, such Distribution

of Senior Lenders and shall be promptly paid over to Agent (to be held and/or applied to the Senior Note Debt by Agent in accordance
with the terms of the Senior Note Debt Documents) until all Senior Note Debt is Paid in Full (upon such event Agent shall deliver
to Senior L/C Lender (or to such other Person entitled thereto under applicable law) amounts and Distributions held and not applied
to the Senior Note Debt), and thereafter to Senior L/C Lender (to be held and/or applied to the Senior L/C Debt by Senior L/C
Lender in accordance with the terms of the Senior L/C Debt Documents) until all Senior L/C Debt is Paid in Full.


 


2.6.Subordination
and Release of Liens and Security Interests; Agreement Not to Contest.

any Collateral which may exist in breach of Subordinated Agent’s agreement pursuant to Section 3.2 and Subordinated
Agent’s representations and warranties pursuant to Section 5.1, shall be and hereby are subordinated for all purposes
and in all respects to the liens and security interests of Senior Lenders in such Collateral, regardless of the time, manner or
order of perfection of any such liens and security interests. In the event that Subordinated Agent obtains any liens or security
interests in the Collateral, Subordinated Agent shall (or shall cause its agent) to promptly execute and deliver to Agent (or
after all of the Senior Note Debt has been Paid in Full, Senior L/C Lender) such termination statements and releases as Agent
or Senior L/C Lender, as applicable, shall request to effect the release of the liens and security interests of Subordinated Agent
and each Subordinated Creditor in such Collateral. In furtherance of the foregoing, Subordinated Agent hereby irrevocably appoints
Agent (and after all of the Senior Note Debt has been Paid in Full, Senior L/C Lender) its attorney-in-fact, with full power of
substitution and with full authority in the place and stead of Subordinated Agent and each Subordinated Creditor and in the name
of Subordinated Agent and each Subordinated Creditor or otherwise, to execute and deliver any document or instrument which Subordinated
Agent or Subordinated Creditor may be required to deliver pursuant to this Section 2.6.


 


(b)Subordinated
Agent, on behalf of itself and each Subordinated Creditor, agrees that it will not at any time contest the validity, perfection,
priority or enforceability of the Senior Debt, the Senior Debt Documents, or the liens and security interests of Senior Lenders
in the Collateral securing the Senior Debt.


 


2.7.Sale,
Transfer or other Disposition of Subordinated Debt.


 


(a)Subordinated
Agent and Subordinated Creditors shall not sell, assign, pledge, dispose of or otherwise transfer all or any portion of the Subordinated
Debt or any Subordinated Debt Document without the prior written consent of the Senior Lenders.


 


(b)Notwithstanding
the foregoing, the subordination effected hereby shall survive any sale, assignment, pledge, disposition or other transfer of

5.3.Representations
and Warranties of Senior L/C Lender. To induce the Subordinated Agent to execute and deliver this Agreement, Senior L/C
Lender hereby represents and warrants to the Subordinated Agent that as of the date hereof: (a) Agent has the power and authority
to enter into, execute, deliver and carry out the terms of this Agreement, all of which have been duly authorized by all proper
and necessary action; (b) the execution of this Agreement by Senior L/C Lender will not violate or conflict with any material
agreement binding upon Senior L/C Lender or any law, regulation or order or require any consent or approval which has not been
obtained; and (c) this Agreement is the legal, valid and binding obligation of Senior L/C Lender, enforceable against Senior
L/C Lender in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, reorganization,
moratorium or similar laws affecting the enforcement of creditors’ rights generally or by equitable principles.


 


6.Subrogation.
Subject to the Payment in Full of all Senior Debt, Subordinated Agent and each Subordinated Creditor shall be subrogated to the
rights of Senior Lenders to receive Distributions with respect to the Senior Debt until the Subordinated Debt is paid in full.
Subordinated Agent, on behalf of itself and each Subordinated Creditor, agrees that in the event that all or any part of a payment
made with respect to the Senior Debt is recovered from the holders of the Senior Debt in a Proceeding or otherwise, any Distribution
received by Subordinated Agent or Subordinated Creditors with respect to the Subordinated Debt at any time after the date of the
payment that is so recovered, whether pursuant to the right of subrogation provided for in this Agreement or otherwise, shall
be deemed to have been received by Subordinated Agent or Subordinated Creditors in trust as property of the holders of the Senior
Debt and Subordinated Agent or Subordinated Creditors shall forthwith deliver the same to the Agent for the benefit of the Senior
Note Lenders (to be held and/or applied to the Senior Note Debt by the Agent in accordance with the terms of the Senior Note Debt
Documents) until all Senior Note Debt is Paid in Full (upon such event Agent shall deliver to Senior L/C Lender (or to such other
Person entitled thereto under applicable law) amounts and Distributions held and not applied to the Senior Note Debt), and thereafter
to Senior L/C Lender (to be held and/or applied to the Senior L/C Debt by Senior L/C Lender in accordance with the Senior L/C
Debt Documents) until all Senior L/C Debt is Paid in Full. A Distribution made pursuant to this Agreement to a Senior Lender which
otherwise would have been made to a Subordinated Agent or Subordinated Creditors is not, as between the Credit Parties and Subordinated
Agent and Subordinated Creditors, a payment by the Credit Parties to or on account of the Senior Debt.


 


7.Modification.
Any modification or waiver of any provision of this Agreement, or any consent to any departure by any party from the terms hereof,
shall not be effective in any event unless the same is in writing and signed by Agent, Senior L/C Lender and Subordinated Agent,
and then such modification, waiver or consent shall be effective only in the specific instance and for the specific purpose given.
Any notice to or demand on any party hereto in any event not specifically required hereunder shall not entitle the party receiving
such notice or demand to any other or further notice or demand in the same, similar or other circumstances unless specifically
required hereunder.


 


8.Further
Assurances. Each party to this Agreement promptly will execute and deliver such further instruments and agreements and
do such further acts and things as may be reasonably requested in writing by any other party hereto that may be necessary in order
to effect fully the terms of this Agreement.


 


9.Notices.
Unless otherwise specifically provided herein, any notice delivered under this Agreement shall be in writing addressed to the
respective party as set forth below and may be personally served, sent by facsimile or email transmission or sent by overnight
courier service or certified or registered United States mail and shall be deemed to have been given (a) if delivered in
person, when delivered; (b) if delivered by facsimile or email transmission, on the date of transmission if transmitted on
a business day before 4:00 p.m. (New York time) or, if not, on the next succeeding business day; (c) if delivered by overnight
courier, one business day after delivery to such courier properly addressed; or (d) if by United States mail, four (4) business
days after deposit in the United States mail, postage prepaid and properly addressed.

mail shall be equally effective as delivery of an original executed counterpart of this Agreement. Any party delivering an executed
counterpart of this Agreement by telecopy or electronic mail also shall deliver an original executed counterpart of this Agreement
but the failure to deliver an original executed counterpart shall not affect the validity, enforceability, and binding effect
of this Agreement.
