No waiver hereunder shall be valid or binding unless set forth in writing and duly executed by the Party against whom enforcement of the waiver is sought. Any such waiver shall constitute a waiver only with respect to the specific matter described in such writing and shall in no way impair the rights of the Party granting such waiver in any other respect or at any other time. Neither the waiver by any Party of a breach of or a default under any provision of this Agreement, nor the failure by any Party, on one or more occasions, to enforce any provision of this Agreement or to exercise any right or privilege hereunder, shall be construed as a waiver of any other breach or default of a similar nature, or as a waiver of any such provision, right or privilege hereunder.
