 A G R E E M E N T 
  
 NOW, THEREFORE, in consideration of the foregoing premises and other good and
valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agrees as follows: 
  
 Section 1. Interpretation. The rules of interpretation specified in the Credit Agreement (including subsection 1.2 thereof) shall be applicable to
this Guarantee. 
  
 Section 2. Resolution of Drafting
Ambiguities. Holdings acknowledges and agrees that it was represented by counsel in connection with the execution and delivery hereof, that it and its counsel reviewed and participated in the preparation and negotiation hereof and that any rule
of construction to the effect that ambiguities are to be resolved against the drafting party (i.e., the Administrative Agent) shall not be employed in the interpretation hereof. 
  
 Section 3. Guarantee. Holdings hereby guarantees, jointly with the Subsidiary Guarantors and severally, as a primary
obligor and not as a surety to each Secured Party and their respective successors and assigns, the prompt payment in full when due (whether at stated maturity, by required prepayment, declaration, demand, by acceleration or otherwise) of the
principal of and interest (including any interest, fees, costs or charges that would accrue but for the provisions of the Bankruptcy Code after any bankruptcy or insolvency petition under the Bankruptcy Code) on the Loans made by the Lenders to, and
the Notes held by each Lender of, Borrower, and all other Obligations from time to time owing to the Secured Parties by any Credit Party under any Credit Document in each case strictly in accordance with the terms thereof (such obligations being
herein collectively called the “Guaranteed Obligations”). Holdings hereby agrees that if Borrower or any Subsidiary Guarantor(s) shall fail to pay in full when due (whether at stated maturity, by acceleration or otherwise) any of
the Guaranteed Obligations, Holdings will promptly pay the same in cash, without any demand or notice whatsoever, and that in the case of any extension of time of payment or renewal of any of the Guaranteed Obligations, the same will be promptly
paid in full when due (whether at extended maturity, by acceleration or otherwise) in accordance with the terms of such extension or renewal. 
  
 (a) To the fullest extent permitted by applicable law, Holdings waives any defense based on or arising out of any defense of Borrower or
the unenforceability of the Obligations or any part thereof from any cause, or the assertion from any cause of the liability of Borrower, other than the final payment in full in cash of the Obligations; provided that subsequent to the final
payment in full in cash of the Obligations other than indemnity and other contingent liabilities not yet due and payable, Holdings 
  

 -2- 








 may additionally assert a defense arising from or in connection with the bad faith, gross negligence or
willful misconduct of any Secured Party in respect of an indemnity Obligation. In any action or proceeding involving any state corporate limited partnership or limited liability company law, or any applicable state, federal or foreign bankruptcy,
insolvency and fraudulent conveyances or transfers, reorganization or other law affecting the rights of creditors generally, if the obligations of Holdings hereunder would otherwise be held or determined to be void, voidable, invalid or
unenforceable, or subordinated to the claims of any other creditors, on account of the amount of its liability hereunder, then, notwithstanding any other provision to the contrary, the amount of such liability shall, without any further action by
Holdings, any Credit Party or any other person, be automatically limited and reduced to the highest amount that is valid and enforceable and not subordinated to the claims of other creditors as determined in such action or proceeding. 
  
 (b) Holdings agrees that the Obligations may at any time and
from time to time exceed the amount of the liability of Holdings hereunder without impairing the guarantee contained in this Guarantee or affecting the rights and remedies of the Administrative Agent or any Secured Party hereunder. 
  
 (c) The guarantee contained in this Guarantee shall remain
in full force and effect until all the Obligations of the Credit Parties (other than any indemnity and other contingent obligations not yet due and payable), including the obligations of each Subsidiary Guarantor under the Subsidiary Guarantee of
even date herewith, shall have been satisfied by payment in full, no Letter of Credit shall be outstanding and the Commitments shall have been terminated, notwithstanding that from time to time during the term of the Credit Agreement the Borrower
may be free from any Obligations. 
  
 (d) No
payment made by Borrower, any of Holdings, any Subsidiary Guarantor, any other guarantor or any other person or received or collected by the Administrative Agent or any Secured Party from any of Borrower, any of Holdings, any Subsidiary Guarantor,
any other guarantor or any other person by virtue of any action or proceeding or any set-off or appropriation or application at any time or from time to time in reduction of or in payment of the Obligations shall be deemed to modify, reduce, release
or otherwise affect the liability of Holdings hereunder, which shall, notwithstanding any such payment (other than any payment made by Holdings in respect of the Obligations or any payment received or collected from Holdings in respect of the
Obligations), remain liable for the Obligations up to the maximum liability of Holdings hereunder until the Obligations are paid in full (other than any indemnity and other contingent Obligations not yet due and payable), no Letter of Credit shall
be outstanding and the Commitments are terminated. 
  

 -3- 








 (e) Holdings agrees that its guarantee hereunder is a guarantee of payment when due, not
of collection, and waives any right to require that any resort be had by the Administrative Agent or any other Secured Party to any of the security held for payment of the Obligations or to any balance of any deposit account for credit on the books
of the Administrative Agent or any other secluded party in favor of the Borrower or any other person. 
  
 Section 4. Right of Contribution. Holdings hereby agrees that to the extent that Holdings shall have paid more than its proportionate share of the
aggregate of any payment made hereunder and by any Subsidiary Guarantor under a Subsidiary Guarantee, Holdings shall be entitled to seek and receive contribution from and against any other Guarantor which has not paid its proportionate share of such
payment. Holdings’ right of contribution shall be subject to the terms and conditions of all Subsidiary Guarantees. The provisions of this Section 4 shall in no respect limit the obligations and liabilities of Holdings to the Administrative
Agent and the Secured Parties, and Holdings shall remain liable to the Administrative Agent and the Secured Parties for the full amount guaranteed by Holdings hereunder. 
  
 Section 5. Right of Set-off. In addition to any rights and remedies of the Administrative Agent and each Secured
Party provided by law, if an Event of Default exists and is continuing or the Loans have been accelerated, Holdings hereby irrevocably authorizes the Administrative Agent and each Secured Party at any time and from time to time, without prior notice
to Holdings, any such notice being waived by Holdings to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held by, and other indebtedness, credits
or claims (in each case, in any currency and whether direct or indirect, absolute or contingent, matured or unmatured) at any time owing by, the Administrative Agent or such Secured Party (or any branch or agency thereof) to or for the credit or the
account of Holdings against any and all Obligations then due and payable by Holdings hereunder (whether at the stated maturity, by acceleration or otherwise). Each Secured Party agrees to promptly notify Holdings and the Administrative Agent after
any such set-off and application made by such Secured Party; provided, however, that the failure to give such notice shall not affect the validity of such set-off and application. 
  
 Section 6. No Subrogation; Subordination. Notwithstanding any payment made by Holdings hereunder or the set-off or
application of funds of Holdings by the Administrative Agent or any Secured Party, Holdings shall not be entitled to be subrogated to any of the rights of the Administrative Agent or any Secured Party against the Borrower or any Subsidiary Guarantor
or any collateral security or guarantee or right of offset held by the Administrative Agent or any Secured Party for the payment of the Obligations, nor shall Holdings be entitled to seek any contribution or reimbursement from the Borrower or any
other Guarantor in respect of payments made by Holdings hereunder, until all amounts owing to the Administrative Agent and the Secured Parties by the Loan Parties on account of the Obligations (other than any contingent indemnity Obligations) are
paid in full, no Letter of Credit shall be outstanding. 
  

 -4- 








 If any amount shall be paid to Holdings on account of such subrogation rights at any time when all of the Obligations
(other than any contingent indemnity Obligations) shall not have been paid in full, such amount shall be held by Holdings in trust for the Administrative Agent and the Secured Parties, segregated from other funds of Holdings, and shall, forthwith
upon receipt by Holdings, be turned over to the Administrative Agent in the exact form received by Holdings (duly indorsed by Holdings to the Administrative Agent, if required), to be applied against the Obligations, whether matured or unmatured, in
such order as is consistent with the Credit Agreement. The payment of any amounts due with respect to any Indebtedness of the Borrower or any Subsidiary Guarantor now or hereafter owing to Holdings by reason of any payment by Holdings under its
guarantee hereunder is hereby subordinated to the prior payment in full in cash of the Obligations (other than any contingent indemnity Obligations). Holdings agrees that it will not demand, sue for or otherwise attempt to collect any such
Indebtedness of the Borrower or any Subsidiary Guarantor to Holdings until the Obligations shall have been paid in full in cash (other than any contingent indemnity Obligations). If, notwithstanding the foregoing sentence, Holdings shall, prior to
the indefeasible payment in full in cash of the Obligations (other than any contingent indemnity Obligations), collect, enforce or receive any amounts in respect of such Indebtedness, such amounts shall be collected, enforced and received by
Holdings as trustee for the Secured Parties and be paid over to the Administrative Agent on account of the Obligations without affecting in any manner the liability of Holdings under the other provisions of its guarantee contained herein.

  
 Section 7. Amendments, etc. with Respect to the
Obligations. Holdings shall remain obligated hereunder notwithstanding that, without any reservation of rights against any Subsidiary Guarantor and without notice to or further assent by any Subsidiary Guarantor, any demand for payment of any of
the Obligations made by the Administrative Agent or any Secured Party may be rescinded by the Administrative Agent or such Secured Party and any of the Obligations continued, and the Obligations, or the liability of any other person upon or for any
part thereof, or any collateral security or guarantee therefor or right of offset with respect thereto, may, from time to time, in whole or in part, be renewed, extended, amended, modified, accelerated, compromised, waived, surrendered or released
by the Administrative Agent or any Secured Party, and the Credit Agreement, the other Credit Documents, any other documents executed and delivered in connection therewith may be amended, modified, supplemented or terminated, in whole or in part, as
the Administrative Agent may deem advisable from time to time, and any collateral security, guarantee or right of offset at any time held by the Administrative Agent or any Secured Party for the payment of the Obligations may be sold, exchanged,
waived, surrendered or released. Holdings’ obligations hereunder shall not be affected by any failure by the Administrative Agent or any Secured Party to protect, secure, perfect or insure any Lien at any time held by it as security for the
Obligations or for the guarantee contained in this Guarantee or any property subject thereto. 
  
 Section 8. Guarantee Absolute and Unconditional. Holdings waives any and all notice of the creation, renewal, extension or accrual of any of the Obligations and notice of 
  

 -5- 








 or proof of reliance by the Administrative Agent or any Secured Party upon the guarantee contained in this Guarantee or
acceptance of the guarantee contained in this Guarantee; the Obligations, and any of them, shall conclusively be deemed to have been created, contracted or incurred, or renewed, extended, amended or waived, in reliance upon the guarantee contained
in this Guarantee; and all dealings between the Borrower and any of the other Credit Parties, on the one hand, and the Administrative Agent and the Secured Parties, on the other hand, likewise shall be conclusively presumed to have been had or
consummated in reliance upon the guarantee contained in this Guarantee. Holdings waives except to the extent that any such waiver would be expressly prohibited by law, diligence, presentment, protest, demand for payment and notice of default or
nonpayment to or upon the Borrower or any of the other Subsidiary Guarantors with respect to the Obligations. Holdings understands and agrees that its guarantee contained herein shall be construed as a continuing, absolute and unconditional
guarantee of payment without regard to (a) the validity or enforceability of the Credit Agreement or any other Credit Document, any of the Obligations or any other collateral security therefor or guarantee or right of offset with respect thereto at
any time or from time to time held by the Administrative Agent or any Secured Party, (b) any defense, set-off or counterclaim (other than a defense of payment or performance and solely after the final payment in full in cash of the Obligations other
than indemnity and other contingent liabilities not yet due and payable, a defense arising from or in connection with the bad faith, gross negligence or willful misconduct of any Secured Party in respect of an indemnity Obligation) which may at any
time be available to or be asserted by any Borrower or any other person against the Administrative Agent or any Secured Party, or (c) any other circumstance whatsoever (with or without notice to or knowledge of the Borrower or Holdings) which
constitutes, or might be construed to constitute, an equitable or legal discharge of the Borrower for the Obligations, or of Holdings under its guarantee contained herein, in bankruptcy or in any other instance. When making any demand hereunder or
otherwise pursuing its rights and remedies hereunder against Holdings, the Administrative Agent or any Secured Party may, but shall be under no obligation to, make a similar demand on or otherwise pursue such rights and remedies as it may have
against any Borrower, any Subsidiary Guarantor or any other person or against any collateral security or guarantee for any Obligations or any right of offset with respect thereto, and any failure by the Administrative Agent or any Secured Party to
make any such demand, to pursue such other rights or remedies or to collect any payments from any Borrower, any Subsidiary Guarantor or any other person or to realize upon any such collateral security or guarantee or to exercise any such right of
offset, or any release of any Borrower, any Subsidiary Guarantor or any other person or any such collateral security, guarantee or right of offset, shall not relieve Holdings of any obligation or liability hereunder, and shall not impair or affect
the rights and remedies, whether express, implied or available as a matter of law, of the Administrative Agent or any Secured Party against Holdings. For the purposes hereof “demand” shall include the commencement and continuance of any
legal proceedings. 
  
 Section 9. Reinstatement. The
guarantee contained herein shall continue to be effective, or be reinstated, as the case may be, if and to the extent at any time payment, or any 
  

 -6- 








 part thereof, of any of the Obligations is rescinded or must otherwise be restored or returned by the Administrative
Agent or any Secured Party upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of the Borrower or any Guarantor, or upon or as a result of the appointment of a receiver, intervenor or conservator of, or trustee or similar
officer for, the Borrower or any Guarantor or any substantial part of its property, or otherwise, all as though such payments had not been made. Holdings agrees that it will indemnify each Secured Party on written demand (as invoiced in reasonable
detail) for all reasonable costs and expenses (including reasonable fees of counsel) incurred by such Secured Party in connection with such rescission or restoration, including any such costs and expenses incurred in defending against any claim
alleging that such payment constituted a preference, fraudulent transfer or similar payment under any bankruptcy, insolvency or similar law, other than any costs or expenses resulting from the gross negligence or bad faith of such Secured Party.

  
 Section 10. Payments. Holdings hereby guarantees that
payments hereunder will be paid to the Administrative Agent without set-off or counterclaim in U.S. Dollars at the Administrative Agent’s office. 
  
 Section 11. Concerning the Administrative Agent. 
  
 (a) The Administrative Agent has been appointed as Administrative Agent pursuant to the Credit Agreement. The actions of the
Administrative Agent hereunder are subject to the provisions of the Credit Agreement. The Administrative Agent shall have the right hereunder to make demands, to give notices, to exercise or refrain from exercising any rights, and to take or refrain
from taking action in accordance with this Guarantee and the Credit Agreement. The Administrative Agent may resign and a successor Administrative Agent may be appointed in the manner provided in the Credit Agreement. Upon the acceptance of any
appointment as the Administrative Agent by a successor Administrative Agent, that successor Administrative Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Administrative Agent
under this Guarantee, and the retiring Administrative Agent shall thereupon be discharged from its duties and obligations under this Guarantee. After any retiring Administrative Agent’s resignation, the provisions hereof shall inure to its
benefit as to any actions taken or omitted to be taken by it under this Guarantee while it was the Administrative Agent. 
  
 (b) The Administrative Agent shall be entitled to rely upon any written notice, statement, certificate, order or other document or any
telephone message believed by it to be genuine and correct and to have been signed, sent or made by the proper person, and, with respect to all matters pertaining to this Guarantee and its duties hereunder, upon advice of counsel selected by it.

  
 (c) With respect to any of its rights and
obligations as a Lender, the Administrative Agent shall have and may exercise the same rights and powers hereunder. 
  

 -7- 








 The term “Lenders,” “Lender” or any similar terms shall, unless the context clearly
otherwise indicates, include Administrative Agent in its individual capacity as a Lender. 
  
 (d) Holdings authorizes the Administrative Agent (on behalf of itself and the other Secured Parties) to (i) take and hold security for the
payment of this Guarantee and the Obligations and exchange, enforce, waive, release any such security (ii) apply such security and direct the order or manner of sale thereof as if in its sole discretion may reasonably determine and (iii) release or
substitute any one ore more endorsers, other guarantors or other obligors. Payment under this Guarantee is secured by the pledges and encumbrances of Collateral pursuant to the Security Agreement in accordance with the Credit Agreement. Reference is
hereby made to the Credit Agreement for a description of the Collateral pledged and the right of the respective parties to such property, to secure all the obligations of Holdings hereunder. 
  
 Section 12. Expenses. Holdings will upon demand pay to the
Administrative Agent the amount of any and all reasonable costs and expenses, including the reasonable fees and expenses of its counsel and the reasonable fees and expenses of any experts and agents which the Administrative Agent may incur in
connection with (i) the collection of the Obligations, (ii) the enforcement and administration hereof, (iii) the exercise or enforcement of any of the rights of the Administrative Agent or any Secured Party hereunder or (iv) the failure by Holdings
to perform or observe any of the provisions hereof. All amounts expended by the Administrative Agent and payable by Holdings under this Section 12 shall be due upon demand therefor (together with interest thereon accruing at the rate per annum equal
to the highest interest rate then payable under the Credit Agreement during the period from, and including, the date on which such funds were so expended to the date of repayment) and shall be part of the Obligations. Holdings’ obligations
under this Section 12 shall survive the termination hereof and the discharge of Holdings’ other obligations under this Guarantee, the Credit Agreement, any Interest Rate Agreement and the other Credit Documents. 
  
 Section 13. Termination; Release. When all the Obligations (other than
contingent indemnification Obligations) have been paid in full and the Commitments of the Lenders to make any Loan or to issue any Letter of Credit under the Credit Agreement shall have expired or been sooner terminated, this Guarantee shall
terminate. 
  
 Section 14. Modification in Writing. No
amendment, modification, supplement, termination or waiver of or to any provision hereof, nor consent to any departure by Holdings therefrom, shall be effective unless the same shall be made in accordance with the terms of the Credit Agreement and
unless in writing and signed by the Administrative Agent. Any amendment, modification or supplement of or to any provision hereof, any waiver of any provision hereof and any consent to any departure by Holdings from the terms of any provision hereof
shall be effective only in the specific instance and for the specific purpose for which made or given. Except where notice is specifically required by this Guarantee or any 
  

 -8- 








 other Credit Document, no notice to or demand on Holdings in any case shall entitle Holdings to any other or further
notice or demand in similar or other circumstances. 
  
 Section
15. Notices. Unless otherwise provided herein or in the Credit Agreement, any notice or other communication herein required or permitted to be given shall be given in the manner and become effective as set forth in the Credit Agreement, as to

designated by such party in a written notice to the other party complying as to delivery with the terms of this Section 15. 
  
 Section 16. GOVERNING LAW. THIS GUARANTEE AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HERETO SHALL BE GOVERNED BY, AND SHALL BE CONSTRUED AND
INTERPRETED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK. 
  
 Section 17. Severability of Provisions. Any provision of this Guarantee 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. 
  
 Section 18. Execution in Counterparts. This Guarantee and any
amendments, waivers, consents or supplements hereto may be executed in any number of counterparts, each of which when so executed and delivered shall be deemed to be an original, but all such counterparts together shall constitute one and the same
agreement. 
  
 Section 19. Business Days. In the event any
time period or any date provided in this Guarantee ends or falls on a day other than a Business Day, then such time period shall be deemed to end and such date shall be deemed to fall on the next succeeding Business Day, and performance herein may
be made on such Business Day, with the same force and effect as if made on such other day. 
  
 Section 20. Relationship. The relationship of the Administrative Agent to Holdings hereunder is strictly and solely that of guarantor and secured party and nothing contained in the Credit Agreement, this
Guarantee, any Interest Rate Agreement or any other document or instrument now existing and delivered in connection therewith or otherwise in connection with the Obligations is intended to create, or shall in any event or under any circumstance be
construed as creating a partnership, joint venture, tenancy-in-common, joint tenancy or other relationship of any nature whatsoever between the Administrative Agent and Holdings other than as lender and borrower.

subject of a voluntary or involuntary proceeding under the Bankruptcy Code or that it shall otherwise be a party to any Federal or state bankruptcy, insolvency, moratorium or similar proceeding to which the provisions relating to the automatic stay
under Section 362 of the Bankruptcy Code or any similar provision in any such law is applicable, then, in any such case, the Administrative Agent shall be entitled to relief from any such automatic stay as it relates to the exercise of any of the
rights and remedies available to the Administrative Agent as provided in this Guarantee or in any other Credit Document.
