Section 4.03 No Waiver, Remedies Cumulative. No (i) failure or delay on the part of the Lender in exercising any right, power or privilege hereunder or under any other Loan Document, or (ii) course of dealing between the Borrower and the Lenders, shall operate as a waiver thereof or constitute an election to affirm any of the Loan Documents; nor shall any single or partial exercise of any right, power or privilege hereunder or under any other Loan Document preclude any other or further exercise thereof or the exercise of any other right, power or privilege hereunder or thereunder.

a) THIS AMENDMENT AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HERETO UNDER THIS AMENDMENT AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK (WITHOUT REGARD TO CONFLICTS OF LAW PRINCIPLES OTHER THAN SECTIONS 5-1401 AND 5-1402 OF THE NEW YORK GENERAL OBLIGATIONS LAW).

b) EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS AMENDMENT AGREEMENT OR THE LOAN DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PERSON HAS REPRESENTED, EXPRESSLY OR OTHERWISE,

c) The Borrower hereby irrevocably appoints the Process Agent, as its authorized agent, to accept and acknowledge on its behalf service of any and all process which may be served in any suit, action or proceeding of the nature referred to above in any New York Court. Such designation and appointment shall be irrevocable until all principal of and interest under the Loan shall have been paid in full in accordance with the provisions hereof.
