Subordination upon Any Distribution of Assets of the Obligors. In the event of any payment or distribution of assets of any Debtor Obligor of any kind or character, whether in cash, property, or securities, upon the dissolution, winding up,
or total or partial liquidation or reorganization, readjustment, arrangement, or similar proceeding relating to such Debtor Obligor or its property, whether voluntary or involuntary, or in bankruptcy, insolvency, receivership, arrangement, or
similar proceedings or upon an assignment for the benefit of 

  
 -4- 








 
creditors, or upon any other marshaling or composition of the assets and liabilities of such Debtor Obligor, or upon the occurrence of an Insolvency Proceeding, or otherwise (such events,
collectively, the “Insolvency Events”): (a) the Discharge of Senior Debt must have occurred before any Subordinated Debt Payment is made; and (b) any Subordinated Debt Payment to which any Creditor Obligor would be entitled
except for the provisions hereof, shall be paid or delivered by the trustee in bankruptcy, receiver, assignee for the benefit of creditors, or other liquidating lender making such payment or distribution directly to (i) the First Lien Agent for
the benefit of the First Lien Lenders for application to the outstanding First Lien Obligations in accordance with the terms of the First Lien Credit Agreement, and (ii) if the First Lien Obligations have been fully paid and satisfied, the
Second Lien Agent for the benefit of the Second Lien Lenders for application to the outstanding Second Lien Obligations in accordance with the terms of the Second Lien Credit Agreement until the Discharge of Senior Debt has occurred. 

SECTION 4. Payments on Subordinated Debt. 

(a) Permitted Payments. So long as no Event of Default has occurred and is continuing, each Debtor Obligor may make, and each Creditor
Obligor shall be entitled to accept and receive, Subordinated Debt Payments expressly allowed, if any, under the Credit Agreements. 
 (b)
No Payment upon Senior Debt Defaults. Upon the occurrence and during the continuance of any Event of Default, and until such Event of Default is waived in accordance with the Credit Agreements, no Debtor Obligor shall make, and no Creditor
Obligor shall accept or receive, any Subordinated Debt Payment. For the avoidance of doubt, once such Event of Default is cured or waived, and so long as no other Event of Default has occurred and is continuing, any Debtor Obligor may make and any
Creditor Obligor may accept or receive any Subordinated Debt payment, including payments scheduled for the period of time when such Event of Default existed, but only to the extent permitted by the Credit Agreements. 

SECTION 5. Subordination of Remedies. Until the Discharge of Senior Debt has occurred, whether or not any Insolvency Event has
occurred, no Creditor Obligor will: 
 (a) accelerate, make demand, or otherwise make due and payable prior to the original due date thereof
any Subordinated Debt; 
 (b) bring, commence, institute, prosecute, or participate in any lawsuit, action, or proceeding, whether private,
judicial, equitable, administrative, or otherwise to enforce its rights or interests in respect of the Subordinated Debt; 
 (c) exercise any
rights under or with respect to guaranties of the Subordinated Debt, if any; 
 (d) exercise any of its rights or remedies in connection with
the Subordinated Debt with respect to any Collateral of any Debtor Obligor; 

  
 -5- 








 (e) exercise any right to set-off or counterclaim in
respect of any Indebtedness, liabilities, or obligations of such Creditor Obligor to any Debtor Obligor against any of the Subordinated Debt; 

(f) in its capacity as a Creditor Obligor, contest, protest, or object to any exercise of secured creditor remedies by either Agent or any
other member of the Lender Groups in connection with the Senior Debt; 
 (g) object to any forbearance by either Agent or any other member of
the Lender Groups in connection with the Senior Debt; or 
 (h) commence, or cause to be commenced, or join with any creditor other than
either Agent or any Lender in commencing, any Insolvency Proceeding against any Debtor Obligor. 
 SECTION 6. Payment over to Agents.
In the event that, notwithstanding the provisions of Sections 2, 3, 4, and 5, any Subordinated Debt Payments shall be received in contravention of such Sections 2, 3, 4, or 5 by any Creditor
Obligor before the Discharge of Senior Debt has occurred, such Subordinated Debt Payments shall be segregated and held in trust for the benefit of the Lender Groups and shall be forthwith paid over or delivered, in the same form as received and with
any necessary endorsements, to (i) First Lien Agent, for application to the outstanding First Lien Obligations in accordance with the terms of the First Lien Credit Agreement, and (ii) if the First Lien Obligations have been fully paid and
satisfied, the Second Lien Agent for application to the outstanding Second Lien Obligations in accordance with the terms of the Second Lien Credit Agreement until the Discharge of Senior Debt has occurred. Agents are authorized to make any such
endorsements as Agents for the respective Creditor Obligors. Such authorization is coupled with an interest and is irrevocable until the Discharge of Senior Debt. 

SECTION 7. Authorization to Agents. If, while any Subordinated Debt is outstanding and before Discharge of Senior Debt has occurred,
any Insolvency Event shall occur and be continuing with respect to any Obligor or its property: (a) each Agent hereby is irrevocably authorized and empowered (in the name of each Obligor or otherwise), but shall have no obligation, to demand,
sue for, collect, and receive every payment or distribution in respect of the Subordinated Debt and give acquittance therefor and to file claims and proofs of claim and take such other action (including voting the Subordinated Debt) as it may deem
necessary or advisable for the exercise or enforcement of any of the rights or interests of such Agent (or any member of the Lender Groups) under any of the Loan Documents; and (b) each Obligor shall promptly take such action as such Agent may
reasonably request (i) to collect the Subordinated Debt for the account of the Lender Groups and to file appropriate claims or proofs of claim in respect of the Subordinated Debt, (ii) to execute and deliver to each Agent such powers of
attorney, assignments, and other instruments as it may reasonably request to enable it to enforce any and all claims with respect to the Subordinated Debt, and (iii) to collect and receive any and all Subordinated Debt Payments.

 SECTION 8. Certain Agreements Of Each Obligor. 

(a) No Benefits. Each Obligor understands that there may be various agreements between the Lender Groups and any other Obligor
evidencing and governing the Senior Debt, and each Obligor acknowledges and agrees that such agreements are not intended to confer any benefits on such Obligor unless such Obligor is also a party thereto (in which case, the rights of such Obligor
are as set forth therein) and that Agents and the other members of the Lender Groups shall have no obligation to such Obligor or any other Person to exercise any rights, enforce any remedies, or take any actions which may be available to them under
such agreements unless such Obligor is also a party thereto (in which case, the rights of such Obligor are as set forth therein). 
 (b)
No Interference. Each Obligor acknowledges that certain other Obligors have granted to Agents for the benefit of the respective Lender Group security interests in substantially all of such other Obligor’s assets, and agrees not to
interfere with or in any manner oppose a disposition of any Collateral by either Agent in accordance with the applicable Loan Documents or applicable law. 

(c) Reliance by Agents and Lender Groups. Each Obligor acknowledges and agrees that Agents and each member of the Lender Groups will
have relied upon and will continue to rely upon the subordination provisions provided for herein and the other provisions hereof in entering into the Loan Documents and making or issuing the financial accommodations thereunder.

Not Affected. Each Creditor Obligor hereby agrees that at any time and from time to time, without notice to or the consent of such Creditor Obligor, without incurring responsibility to such Creditor Obligor, and without impairing or releasing
the subordination provided for herein or otherwise impairing the rights of either Agent or any other member of the Lender Groups hereunder: (i) the time for any Debtor Obligor’s performance of or compliance with any of its agreements
contained in the Loan Documents may be extended or such performance or compliance may be waived by either Agent or any other member of the Lender Groups; (ii) the agreements of any Debtor Obligor with respect to the Loan Documents may from time
to time be modified by such other Debtor Obligor, either Agent or any other member of the Lender Groups for the purpose of adding any requirements thereto or changing in any manner the rights and obligations of such Debtor Obligor, either Agent or
any other member of the Lender Groups thereunder; (iii) the manner, place, or terms for payment by any Debtor Obligor of Senior Debt or any portion thereof may be altered or the terms for payment extended, or the Senior Debt of any Debtor

manner for Senior Debt may be discharged, released, or substituted; and (vii) all other rights against the Debtor

Obligors, any other Person, or with respect to any Collateral may be exercised (or either Agent or any other member of the Lender Groups may waive or refrain from exercising such rights as
provided in the Loan Documents or under applicable law) in each case, in accordance with the applicable Loan Documents and applicable law. 

(f) Rights of Agent Not to Be Impaired. No right of either Agent or any other member of the Lender Groups to enforce the subordination
provided for herein or to exercise its other rights hereunder shall at any time in any way be prejudiced or impaired by any act or failure to act by any Obligor, Agent or any other member of the Lender Groups hereunder or under or in connection with
the other Loan Documents or by any noncompliance by the other Obligors with the terms and provisions and covenants herein or in any other Loan Document, regardless of any knowledge thereof either Agent or any other member of the Lender Groups may
have or otherwise be charged with. 
 (g) Financial Condition of the Obligors. No Obligor shall have any right to require either Agent
to obtain or disclose any information with respect to: (i) the financial condition or character of any other Obligor or the ability of any other Obligor to pay and perform any or all of Senior Debt; (ii) the Senior Debt; (iii) the
Collateral or other security for any or all of the Senior Debt; (iv) the existence or nonexistence of any guarantees of, or any other subordination agreements with respect to, all or any part of the Senior Debt; (v) any action or inaction
on the part of Agents or any other Person; or (vi) any other matter, fact, or occurrence whatsoever.

Guaranties. Except as expressly permitted by the Credit Agreements, no Creditor Obligor shall (i) acquire any Lien on any asset of any Debtor Obligor or (ii) accept any guaranties from any other Obligor or from any other Subsidiary of
any Loan Party for the Subordinated Debt. 
 SECTION 9. Subrogation. With respect to any payments or distribution in cash, property,
or other assets that any Creditor Obligor pays over to Agents (for the benefit of the Lender Groups) under the terms of this Agreement, each Creditor Obligor shall be subrogated to the rights of Agents and the other members of the Lender Groups;
provided, however, that each Creditor Obligor agrees not to assert or enforce any such rights of subrogation it may acquire as a result of any such payment or distribution hereunder until the Discharge of Senior Debt has occurred;
provided further, however, that no Creditor Obligor shall exercise or enforce any such rights against any Debtor Obligor (including after the Discharge of Senior Debt) if all or any portion of the Senior Debt shall have been satisfied
in connection with an exercise of remedies by Agents in respect of the Equity Interests of such Debtor Obligor whether pursuant to the Guaranty and Security Agreement or otherwise. 

SECTION 10. Continuing Agreement; Reinstatement. 

(a) Continuing Agreement. This Agreement is a continuing agreement of subordination and shall continue in effect and be binding upon
each Obligor until the Discharge of Senior Debt has occurred. The subordinations, agreements, and priorities set forth herein shall remain in full force and effect regardless of whether any party hereto in the future seeks to


  
 -8- 








 
rescind, amend, terminate, or reform, by litigation or otherwise, its respective agreements with the other Obligor. This Agreement shall be applicable both before and after the commencement of
any Insolvency Proceeding and all converted or succeeding cases in respect thereof. The relative rights of parties hereto in or to any distributions from or in respect of any Collateral or proceeds of Collateral, shall continue after the
commencement of any Insolvency Proceeding. Accordingly, the provisions of this Agreement are intended to be and shall be enforceable as a subordination agreement within the meaning of Section 510 of the Bankruptcy Code. 

(b) Reinstatement. This Agreement shall continue to be effective or shall be reinstated (and the amount of Senior Debt shall be
reinstated), as the case may be, if, for any reason, any payment of the Senior Debt shall be rescinded or must otherwise be restored by either Agent or any other member of the Lender Groups to any Loan Party, whether as a result of an Insolvency
Event or otherwise. 
 SECTION 11. Transfer of Subordinated Debt. No Obligor may assign or transfer its rights and obligations in
respect of the Subordinated Debt without the prior written consent of Agents, and any such transferee or assignee, as a condition to acquiring an interest in the Subordinated Debt shall agree to be bound hereby, in form reasonably satisfactory to
Agents. 
 SECTION 12. Obligations of the Obligors Not Affected. The provisions of this Agreement are intended solely for the purpose
of defining the relative rights of each Creditor Obligor against each Debtor Obligor, on the one hand, and of Agents and the other members of the Lender Groups against each Creditor Obligor, on the other hand. Nothing contained in this Agreement
shall (i) impair, as between each Creditor Obligor and any Debtor Obligor, the obligation of the Debtor Obligor to pay its respective obligations with respect to the Subordinated Debt as and when the same shall become due and payable, or
(ii) otherwise affect the relative rights of any Creditor Obligor against any Debtor Obligor, on the one hand, and of the creditors (other than Agents or the other members of the Lender Groups) of the Debtor Obligors against the Debtor
Obligors, on the other hand.

expense all such further agreements, instruments, certificates, financing statements, documents, and assurances, and perform such acts as either Agent reasonably shall deem necessary or appropriate to effectuate the purposes of this Agreement, and
promptly provide Agents with evidence of the foregoing reasonably satisfactory in form and substance to Agents.

or delivered in care of Borrower in accordance with the notice provisions set forth in the Credit Agreements or, as to any party, at such other address as shall be designated by such party in a written notice to the other party in writing. 

SECTION 15. No Waiver; Cumulative Remedies. No failure on the part of either Agent or any other member of the Lender Groups to
exercise, and no delay in exercising, any right, remedy, power, or privilege hereunder or under any other Loan Document shall operate as a waiver thereof, nor shall any single or partial exercise of any such right, remedy, power, or privilege
preclude any other or further exercise thereof or the exercise of any other right, remedy, power, or privilege. The rights and remedies under this Agreement are cumulative and not exclusive of any rights, remedies, powers, and privileges that may
otherwise be available to Agents or the other members of the Lender Groups. 
 SECTION 16. Costs and Expenses. The Obligors, jointly
and severally, agree to pay to Agents promptly after demand therefor all Lender Group Expenses under each Credit Agreement in connection with this Agreement, including in connection with the negotiation, preparation, execution, delivery, and

effect until the Discharge of Senior Debt has occurred. The foregoing to the contrary notwithstanding, the obligations of each Obligor under Section 9 and Section 16 shall survive the Discharge of
Senior Debt. 
 SECTION 18. Benefits of Agreement. This Agreement is entered into for the sole protection and benefit of the
Obligors, the Agents and the other members of the Lender Groups and their respective successors and assigns, and no other Person shall be a direct or indirect beneficiary of, or shall have any direct or indirect cause of action or claim in

(a) Entire Agreement. This Agreement, together with the other respective Loan Documents, constitutes the entire agreement of each of the
Obligors and the Lender Groups with respect to the matters set forth herein and shall not be contradicted or qualified by any other agreement, oral or written, before the date hereof. 

(b) Amendments and Waivers. No amendment to or waiver of any provision of this Agreement shall in any event be effective unless the same
shall be in writing and signed by each of the Obligors and Agents; and no waiver of any provision of this Agreement, or consent to any departure by any Obligor from any provision hereof, shall in any event be effective unless the same shall be in
writing and signed by Agents. Any such amendment, waiver, or consent shall be effective only in the specific instance and for the specific purpose for which given. 

(c) Conflicts with Subordinated Debt Documents. In case of any conflict or inconsistency between any terms of this Agreement, on the one
hand, and any documents or instruments in respect of the Subordinated Debt, on the other hand, then the terms of this Agreement shall control. 

(d) Conflicts with Credit Agreements. In case of any conflict or inconsistency between any terms of this Agreement, on the one hand, and
any of the terms and provisions of either Credit Agreement, on the other hand, then the terms and provisions of the respective Credit Agreement shall control. 

SECTION 22. Severability of Provisions. Each provision of this Agreement shall be severable from every other provision of this
Agreement for the purpose of determining the legal enforceability of any specific provision. 
 SECTION 23. Interpretation. Neither
this Agreement nor any uncertainty or ambiguity herein shall be construed against any member of the Lender Groups or any Obligor, whether under any rule of construction or otherwise. On the contrary, this Agreement has been reviewed by all parties
and shall be construed and interpreted according to the ordinary meaning of the words used so as to accomplish fairly the purposes and intentions of all parties hereto. 

SECTION 24. Counterparts; Telefacsimile or Other Electronic Delivery. This Agreement may be executed in any number of counterparts and
by different parties on separate counterparts, each of which, when executed and delivered, shall be deemed to be an original, and all of which, when taken together, shall constitute but one and the same agreement. Delivery of an executed counterpart
of this Agreement by telefacsimile or other electronic method of transmission shall be equally as effective as delivery of an original executed counterpart of this Agreement. Any party delivering an executed counterpart of this Agreement by
telefacsimile or other electronic method of transmission 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.

 SECTION 25. New Subsidiaries. Each Obligor shall cause any Subsidiary (whether by
acquisition or formation) of any Loan Party that is required pursuant to Section 5.11 of each Credit Agreement to execute a joinder to the respective Guaranty and Security Agreement or Credit Agreement, within 10 Business
Days of such acquisition or formation, as the case may be, to execute and deliver to Agents a joinder to this Agreement in a form reasonably satisfactory to Agents. Upon the execution and delivery of such a joinder by such Subsidiary, such
Subsidiary shall become an Obligor hereunder with the same force and effect as if originally named as an Obligor herein. The execution and delivery of any agreement or instrument adding an additional Obligor as a party to this Agreement shall not
require the consent of any other Obligor hereunder. The rights and obligations of each Obligor hereunder shall remain in full force and effect notwithstanding the addition of any new Obligor hereunder as though such new Obligor had originally been
named an Obligor hereunder on the date of this Agreement.
