Fiscal Year. 
 (b) General. All references to “this Agreement” in the Credit Agreement and to “the Credit

the representations and warranties made as of a specific date) are true and correct in all material respects as of the date hereof and with the same effect as though made on and as of the date hereof. 

(b) After giving effect to this Amendment, no Default or Event of Default and no event or condition which, with the giving of notice or
lapse of time or both, would constitute such a Default or Event of Default, has occurred and is continuing or result herefrom.

authorized by all necessary action (corporate or otherwise) on the part of the Borrower, (ii) this Amendment is the legal, valid and binding obligation of the Borrower, enforceable against the Borrower in accordance with its terms, and

Agreement and the other Loan Documents shall remain in full force and effect in accordance with their terms and are hereby ratified and confirmed. Other than as expressly set forth in Section 1 hereof, the execution, delivery and effectiveness
of this Amendment shall not operate as a waiver of any existing or future Default or Event of Default, whether known or unknown or any right, power or remedy of the Administrative Agent or the Lenders under the Credit Agreement or Security
Agreement, nor constitute a waiver of any provision of the Credit Agreement or Security Agreement, except as specifically set forth herein. 
 (b) The Borrower hereby (i) reaffirms all of its agreements and obligations under the Security Documents, (ii) reaffirms that all Obligations of the Borrower under or in connection with the

Administrative Agent and the Lenders and the respective successors and assigns of the Administrative Agent and the Lenders. 

(d) This Amendment may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which
when so executed and delivered shall be deemed to be an original and all of which taken together shall constitute one and the same instrument.
