No failure on the part of the Lender to exercise, and no delay in exercising, any right hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any right hereunder preclude any other or future exercise thereof or the exercise of any other right. The remedies provided herein are cumulative and not exclusive of any remedies provided by law.
