Accordingly, instead of requiring any such proof, as to deliveries, operations, maintenance and repair issues only, the OWNER and SUPPLIER agree to the following:

That as liquidated damages for delay (but not as penalty) for the EXCHANGE, SUPPLIER shall pay OWNER five hundred dollars ($500.00) per day per location after the response times included in section 3.01, D. for each incident EXCHANGE is not performed. This amount was calculated based on labor and material costs expended by NTMWD in monitoring and responding to an odor complaint. The OWNER will be the sole judge as to whether the EXCHANGE has been timely completed. Assessment of Liquidated Damages by the OWNER shall not constitute a waiver of the Owner’s right to sue and collect additional damages which OWNER may sustain by the failure of the SUPPLIER to perform in accordance with the terms of this Contract.
