5.6 Delays or Omissions. It is agreed that 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 any similar breach, default or noncompliance thereafter occurring. It is further agreed that any waiver, permit, consent, or approval of any kind or character on any partys part of any breach, default or noncompliance under the Agreement or any waiver on such partys part of any provisions or conditions of this Agreement must be in writing and shall be effective only to the extent specifically set forth in such writing.
