"The applicable price hurdle must be achieved during the relevant performance period (as set forth in the table below corresponding to the price hurdle) in order for the applicable tranche of RSU Awards to be earned, but once a price hurdle is achieved, the price hurdle need not be maintained in order for the applicable RSU Award tranche to continue to vest based on service. Once a price hurdle is no longer achievable due to the lapse of a performance period or if Mr. Sijbrandij ceases to be the CEO, any then-unvested portion of the RSU Award will be immediately forfeited."
