3.12    Waiver. No waivers of any breach of this Agreement extended by any party hereto to any other party shall be construed as a waiver of any rights or remedies of any other party hereto or with respect to any subsequent breach.

3.13    Delays or Omissions. No delay or omission to exercise any right, power or remedy accruing to any party, upon any breach, default or noncompliance by another party under this Agreement shall impair any such right, power or remedy, nor shall it be construed to be a waiver of any such breach, default or noncompliance, or any acquiescence therein, or of or in any similar breach, default or noncompliance thereafter occurring. Any waiver, permit, consent or approval of any kind or character on any party’s behalf of any breach, default or noncompliance under this Agreement or any waiver on such party’s behalf of any provisions or conditions of the Agreement must be in writing and shall be effective only to the extent specifically set forth in such writing.
