Buyer shall not by any act (except by a written instrument pursuant to Section 14 hereof), delay, indulgence, omission or otherwise be deemed to have waived any right or remedy hereunder or to have acquiesced in any default or event of default or in any breach of any of the terms and conditions hereof. No failure to exercise, nor any delay in exercising, on the part of Buyer, any right, power or privilege hereunder shall operate as a waiver thereof. No single or partial exercise of any right, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege. A waiver by Buyer of any right or remedy hereunder on any one occasion shall not be construed as a bar to any right or remedy which Buyer would otherwise have on any future occasion. The rights and remedies herein provided are cumulative, may be exercised singly or concurrently and are not exclusive of any rights or remedies provided by law.
