No Waiver of Rights. A Party’s failure in one or more instances to exercise or enforce any right provided by this Agreement or by law does not waive its right to exercise the right in any later instance. No waiver of any breach of this Agreement shall be held to constitute a waiver of any other or subsequent breach. To be effective, a waiver must be expressly written and signed by the Party to be bound. A course of dealing or performance is not a waiver unless ratified in writing by the Party to be bound.
