The actual capital cost ("Actual Capital Cost") of the Facility Program will be calculated on a time and materials basis as follows: in performing the Facility Program, Nordion will provide labor at the rate of [...***...] per hour ([...***...] per hour after November 1, 1997), and will provide materials and equipment at Nordion's cost plus an additional [...***...] administrative fee; provided, however, that no such administrative fee shall be charged on any travel expenses Nordion incurs pursuant to the Facility Program. (b) MAXIMUM ACTUAL CAPITAL COST. Except as set forth in Section 2.4, in no event will the Actual Capital Cost invoiced to Coulter exceed [...***...] (the "Maximum Actual Capital Cost") without the prior written authorization of Coulter. The Maximum Actual Capital Cost was derived from a preliminary engineering estimate for a manually operated facility with capacity to process [...***...] vials per Batch. Upon request of Coulter and as agreed by Nordion, the scope of the Primary Facility shall be expanded to be capable of processing [...***...] vials per Batch ("Scope Change"). The Scope Change shall include the installation of a third Hot Cell, as well as the addition of automated systems for dispensing, QC testing and packaging.
