              strict performance by the other party of any provision of this
              Agreement shall not constitute a waiver, or affect or diminish the
              right thereafter to demand strict compliance and performance of
              this Agreement

         7.   This Agreement (including Schedule A) shall constitute the entire

              excess purchases will be governed by separate agreement of the
              parties. Except as specified in this Agreement, the terms of sale
              and rights of the parties with respect to any specific order shall
