defined. 
 SECTION 1. GUARANTY. 

(a) Each of the undersigned hereby irrevocably, absolutely, and unconditionally guarantees to each Lender the prompt, complete, and full
payment when due, and no matter how the same shall become due, of all Obligations, as defined in the Credit Agreement, including all principal of and all interest on the Advances, and all other sums payable in connection therewith. 

(b) Each of the undersigned hereby irrevocably, absolutely, and unconditionally guarantees to each Lender the prompt, complete and full
payment, when due, and no matter how the same shall become due, of all obligations and undertakings of the Borrowers to such Lender under, by reason of, or pursuant to any of the Loan Documents. 






 (c) If the Borrowers shall for any reason fail to pay any Obligation, as and when such Obligation
shall become due and payable, whether at its stated maturity, as a result of the exercise of any power to accelerate, or otherwise, the undersigned will, upon demand by the Administrative Agent, pay such Obligation in full to the Administrative
Agent for the benefit of the Lender to whom such Obligation is owed. 
 (d) If either the Borrower or either of the undersigned fails to pay
any Obligation as described in the immediately preceding subsections (a), (b), or (c), each of the undersigned will incur the additional obligation to pay to the Administrative Agent, and each of the undersigned will forthwith upon demand by the
Administrative Agent pay to the Administrative Agent, the amount of any and all reasonable expenses, including fees and disbursements of the Administrative Agent’s counsel and of any experts or agents retained by the Administrative Agent, which
the Administrative Agent may incur as a result of such failure. 
 (e) The liability of each of the undersigned hereunder shall be limited
to the maximum amount of liability that can be incurred without rendering this Guaranty, as it relates to such Person, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer, and not for any greater amount. 

(f) The books and records of the Lenders showing the amount of any of the Obligations shall be admissible in evidence in any action or
proceeding, and shall be binding upon the Guarantors and conclusive for the purpose of establishing the amount of the Obligations. 

SECTION 2. OBLIGATIONS UNDER THE GUARANTY. Each of the undersigned hereby agrees, as of the date first above written, to be bound

“Guarantor” shall also mean and be a reference to each of the undersigned, and each reference in any other Loan Document to a “Guarantor” shall also mean and be a reference to each of the undersigned. 

SECTION 3. COUNTERPARTS; EFFECTIVENESS. This Joinder Agreement may be executed in counterparts (and by different parties hereto in
different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. Delivery of an executed counterpart of a signature page of this Joinder Agreement by telecopy shall be

LAW OF THE STATE OF NEW YORK.

(c) WAIVER OF VENUE. EACH OF THE UNDERSIGNED IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW,

SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE
