Between 0% and 200% of the target number will be earned based on total shareholder return relative to a peer group of companies over a three-year performance period covering AngioDynamics, Inc.'s fiscal years 2014, 2015 and 2016.  A portion of the shares may be earned based on performance in each year of the performance period.  Any shares that do not vest at the end of the performance period are forfeited.</footnote>
