Gentex Corporation Amended and Restated Annual Incentive Performance-Based Bonus Plan (as amended on February 15, 2018) filed as an exhibit to Registrant's Report on Form 10-K dated February 21, 2018

(i)    Profit-Sharing Bonus - In lieu of participation in the Profit Sharing Bonus Plan of the Corporation (in which all employees participate), Participants shall be eligible to participate in this Plan.

For purposes of determining such annual performance bonuses, the Committee will each year establish a threshold, a target, and a maximum for each applicable performance metric, along with incentive ratios applicable to each Participant with respect to such threshold, target, and maximum. The applicable incentive ratio is a percentage of base compensation for a Participant, designated by the Committee, which is then multiplied by the weighting of a particular performance metric to determine the amount of a performance bonus payable to a Participant to the extent the threshold, target, or maximum for a performance metric is met or exceeded. To the extent performance exceeds the established threshold or target, as applicable, for any performance metric, but does not meet the established target or maximum, as applicable, a pro rata portion of the potential bonus payable will be paid as a performance bonus (based on the percentage of the target or maximum, as applicable, achieved in excess of the threshold or target, as applicable). Calculation of performance bonuses will be determined using linear interpolation for performance above the threshold up to the target and above the target up to the maximum. Notwithstanding the foregoing, based on any criteria it establishes in its discretion, the Committee reserves the right to continue to pay individual performance bonuses to any Participant; provided, however, that in no event shall any annual bonuses payable under this Plan exceed two hundred fifty percent (250%) of base compensation.
