         provide PSS [ * ] urine controls and [ * ] point-of-care devices with
         every [ * ] point-of-care devices that PSS orders.

         the first three-month period of each twelve-month period will
         constitute a firm purchase order that will obligate PSS to purchase the
         indicated number of Product devices. The forecasted demand for the
         fourth, fifth, and sixth months of each Rolling Forecast shall be
         relied upon by Ostex for the purposes of manufacturing and supply
         obligations hereunder, but PSS may within the subsequent Rolling

         In the event any proceeding is brought to enforce or interpret any of
