2.    LIMITATION.

2.1    The waiver set forth in Section 1 hereof is effective only for the purposes set forth herein and shall be limited precisely as written and shall not be deemed to (a) to be a forbearance, waiver or modification of any other term or condition of the Loan Agreement or of any other instrument or agreement referred to therein or to prejudice any right or remedy which Bank may now have or may have in the future under or in connection with the Loan Agreement or any instrument or agreement referred to therein; (b) to be a consent to any future amendment or modification, forbearance or waiver to any instrument or agreement the execution and delivery of which is consented to hereby, or to any waiver of any of the provisions thereof; or (c) to limit or impair Bank’s right to demand strict performance of all terms and covenants as of any date.

3.8    As of the date hereof, Borrower has no defenses against the obligation to pay any of the amounts constituting all or a part of Borrower’s Obligations.
