The percentage of options that may vest and become exercisable, if any, are 100%, 50%, and 25%, respectively, based upon the volume-weighted average price of Pro-Dex's common stock equaling or exceeding the applicable exercise price for the 60 trading days immediately preceding the date the option becomes exercisable, six months from the date the option becomes exercisable, or twelve months from the date the option becomes exercisable, respectively.
