I agree to abide by the confidentiality and non-compete details in the attached Employment

I agree that Gentex Corporation has fulfilled its obligation to me in terms of all past payment of
wages, and any other earned benefit that is due to me (vacation pay earned, etc.). I understand
that I will not accrue additional vacation time after December 31, 2011. I understand that my
medical health insurance and benefits will end on December 31, 2011.

I understand that I will receive a prorated amount of my 5,760 restricted stock grant (issued on

my fulfillment of my responsibilities under this agreement. I understand that I must adhere to all
Gentex blackout periods. Additionally, I have the ability to purchase my restricted options which
will be taxed as income.




I acknowledge that I have returned, or have arranged to return, all company property that I was
entrusted with, or agree to pay for lost or unsalvageable company property. I also will complete
an expense report for all outstanding receipts.

Except as prohibited by law, for the consideration stated above, I release Gentex, along with its
shareholders, owners, directors, officers, employees, agents, insurers, and representatives from
