remedy referred to herein or now or hereafter available at law, by statute or otherwise. To the extent permitted by applicable law, the Company hereby agrees to waive, and does hereby absolutely and irrevocably waive and relinquish, the benefit and
advantage of any valuation, stay, appraisement, extension or redemption law now existing or which may hereafter exist, which, but for this provision, might be applicable to any sale made under the judgment, order or decree of any court, or
otherwise, based on this Promise or on any claim for principal of, or interest on, this Promise. 
 Section 7. Ranking and Priority of
Promise. 
 (a) Subordination. The Company, for itself, its successors and assigns, covenants and agrees, and the
Holder, by its acceptance of this Promise likewise covenants and agrees, that anything herein or any related agreement or instrument to the contrary notwithstanding, the indebtedness evidenced by or arising on account of this Promise 

  

 -4- 

 
(or any renewal or extension thereof), including, without limitation, principal and interest, is and shall be subordinate and subject in right of payment to
the prior payment in full of all Senior Debt of the Company, whether outstanding on the date hereof or incurred hereafter, to the extent and in the manner set forth herein. 
 (b) Extent of Subordination. If any payment default has occurred and is continuing on any Senior Debt, or a non-payment default has
occurred and is continuing on the Senior Debt and the Holder has received notice of such non-payment default, then the Company shall not make any direct or indirect payment or distribution of any kind or character, whether in cash, property or
securities, to, or for the benefit of, the Holder pursuant to or in respect of this Promise (whether for principal or interest or otherwise, and whether before, after or in connection with any dissolution, winding up, liquidation or reorganization
or receivership proceeding or upon an assignment for the benefit of creditors or any other marshalling of the assets and liabilities of the Company). Notwithstanding the preceding sentence, if the Senior Debt has been paid in full or the relevant
default has been cured or waived, the Company may make payments in respect of this Promise. 
 (c) Distributions in
Bankruptcy. Upon any distribution in any bankruptcy or similar proceeding, any distribution to which the Holder is entitled shall be paid directly to the holders of Senior Debt to the extent necessary to make payment in full of all Senior Debt
remaining unpaid after giving effect to all other distributions to or for the benefit of the holders of Senior Debt. 
 (d)
Priority in Liquidation and Similar Proceedings. In the event of any liquidation, dissolution or winding up of the Company, the Debt outstanding hereunder shall be pari passu in right of payment to all limited liability company
interests, reserves or other equity interests of the Company. 
 (e) Application of Distributions. If any distribution,
payment or deposit to redeem, defease or acquire the Debt outstanding hereunder shall have been received by the Holder at a time when such distribution was prohibited by the provisions of this Section 7, then, unless such distribution is no
longer prohibited by this Section 7, such distribution shall be received and applied by the Holder for the benefit of the holders of Senior Debt, and shall be paid or delivered by the Holder to the holders of Senior Debt for application to the
payment of all Senior Debt. 
 (f) Subrogation Rights. The Holder shall not have any subrogation or other rights of
recourse to any security in respect of any Senior Debt until such time as all Senior Debt shall have been paid in full. Upon the payment in full of all Senior Debt, the Holder shall be subrogated to the rights of the holders of Senior Debt to
receive distributions applicable to Senior Debt until all amounts owing in respect of the Debt outstanding hereunder shall be so paid. No distributions to the holders of Senior Debt which otherwise would have been made to the Holder shall, as
between the Company and the Holder, be deemed to be payment by the Company to or on account of Senior Debt. If any distribution to which the Holder would otherwise have been entitled shall have been applied pursuant to the provisions of this
Section 7 to the payment of Senior Debt, then the Holder shall be entitled to receive from the holders of such Senior Debt 

  

 -5- 

 
any distributions received by such holders of Senior Debt in excess of the amount sufficient to pay all amounts payable on such Senior Debt to the extent
provided herein. 
 (g) Reliance. Upon any distribution in a bankruptcy or similar proceeding, the Holder shall be
entitled to rely upon any order or decree made by any court of competent jurisdiction in which the proceeding is pending, or agent or other Person making any distribution for the purpose of ascertaining the Persons entitled to participate in such
distribution, the holders of Senior Debt and other Debt of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Section 7. 
 (h) Ratable Distributions. Any distribution otherwise payable to the Holder made to holders of Senior Debt pursuant to this
Section 7 shall be made to such holders of Senior Debt ratably according to the respective amount of Senior Debt held by each, taking into account any priorities which may be established among the holders of such Senior Debt. 
 (i) Obligations Not Impaired. Nothing contained in this Promise is intended to or will impair as between the Company, its
creditors, and the Holder, the obligation of the Company, which is absolute and unconditional, to pay to the Holder as and when amounts become due and payable in accordance with the terms of this Promise or affect the relative rights of the Holder
and the creditors of the Company. 
 (j) Further Actions. The Holder, by its acceptance hereof, agrees to take such
further action as may be reasonably requested by the Company and/or by law in order to effectuate the subordination as provided herein. 
 Section 8. Amendments and Waivers. Neither this Promise nor any term hereof may be amended or waived orally or in writing, except that any term of this Promise may be amended and the observance of any term of this Promise may be
waived (either generally or in a particular instance and either retroactively or prospectively) with (but only with) the written consent of the Company and the Holder. 
 Section 9. Captions. The captions in this Promise are included for convenience of reference only and do not form a part of this Promise or in any way limit or affect its interpretation or construction.

 Section 10. Notices. All notices, consents, waivers and other communications required or permitted by this Promise shall be in
writing and shall be deemed given to a party when (a) delivered to the appropriate address by hand or by nationally recognized overnight courier service (costs prepaid); (b) sent by facsimile with confirmation of transmission by the
transmitting equipment; or (c) received or rejected by the addressee, if sent by certified mail, return receipt requested, in each case to the following addresses and facsimile numbers and marked to the attention of the Person (by name or

 Section 11. Restrictions on Transfer. THE HOLDER MAY NOT SELL, TRANSFER, ASSIGN, ENCUMBER
