The Agreement and all other Loan Documents shall remain in full force and effect in all respects as if the unpaid balance of the principal outstanding, together with interest accrued thereon, had originally been payable and secured as provided for therein, as amended from time to time and as modified by this Amendment. Nothing herein shall affect or impair any rights and powers which Agent may have under the Agreement and any and all related Loan Documents.
