We obtain an asymptotic estimation of the number of collisions under Kac¿s condition for the cases where the direction-switching processes have the same parameters and different parameters. We also consider the application of these results to evaluate Margrabe¿s spread option for two assets of spot prices modeled by two telegraph processes.
