Time is of the essence in each of the Loan Documents. Subject to the limitations on recourse set forth in the Note, the remedies of Mortgagee as provided herein or in any other Loan Document or at law or in equity shall be cumulative and concurrent, and may be pursued singly, successively, or together at the sole discretion of Mortgagee, and may be exercised as often as occasion therefor shall occur; and neither the failure to exercise any such right or remedy nor any acceptance by Mortgagee of payment of Indebtedness in default shall in any event be construed as a waiver or release of any right or remedy. Neither this instrument nor any other Loan Document may be modified or terminated orally but only by agreement or discharge in writing and signed by Mortgagor and Mortgagee. If any of the provisions of any Loan Document or the application thereof to any persons or circumstances shall to any extent be invalid or unenforceable, the remainder of such Loan Document and each of the other Loan Documents, and the application of such provision or provisions to persons or circumstances other than those as to whom or which it is held invalid or unenforceable, shall not be affected thereby, and every provision of each of the Loan Documents shall be valid and enforceable to the fullest extent permitted by law.
