the transactions contemplated hereby or thereby, or for recognition or enforcement of any judgment, and each of the parties hereto
hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined
in such New York state court or, to the extent permitted by applicable law, such Federal court. Each of the parties hereto agrees
that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on
the judgment or in any other manner provided by law. Nothing in this Amendment or any other Loan Document shall affect any right
that the Administrative Agent or any Lender may otherwise have to bring any action or proceeding relating to this Amendment or
any other Loan Document against the Borrower or its properties in the courts of any jurisdiction.

unconditionally waives any objection which it may now or hereafter have to the laying of venue of any such suit, action or
proceeding described in paragraph (b) of Section 10.5 of the Credit Agreement and brought in any court referred to in paragraph
(b) of Section 10.5 of the Credit Agreement. Each of the parties hereto irrevocably waives, to the fullest extent permitted by
applicable law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

 

(d)Each party to this Amendment
irrevocably consents to the service of process in the manner provided for notices in Section 10.1 of the Credit Agreement. Nothing
in this Amendment or in any other Loan Document will affect the right of any party hereto to serve process in any other manner
permitted by law.

Agreement or an accord and satisfaction in regard thereto.

be deemed an original and all of which, taken together, shall be deemed to constitute one and the same instrument. Delivery of
