The failure of a Party to insist upon a strict adherence to any term of this Agreement on any occasion shall not be considered a waiver of any right thereafter to insist upon a strict adherence to that term or any other term of this Agreement. No waiver by a Party of any default or breach of this Agreement shall be construed as a waiver of any other provision, condition, or term hereof or of any other default or breach of the same provision, condition, or term. No delay in the exercise and no single or partial exercise by a Party of any right, remedy, or power hereunder, in equity, or at law, shall preclude any other or further exercise thereof or the exercise of any other right, remedy, or power existing hereunder, in equity, or at law. Any waiver must be in writing and signed by a duly authorized representative of the Party issuing the waiver.
