     foregoing, in no event shall the Ricochet version of the Product be
     available for delivery prior to [**] following the commercial availability
     of the CDPD version of the Product. Notwithstanding section 4.1, SWD agrees
     that GOA may make payment of the per unit purchase price of US$[**], in
