Exhibit 10.1

Separation from Service Agreement

To:     Steven Dykman

From: Gentex Corporation

Date:  May 17, 2013

I, Steven Dykman, understand that my employment with Gentex Corporation will end effective December 31, 2014 (“Separation Date”). I will be on paid administrative leave starting May 17, 2013 and lasting through December 31, 2014 (“Administrative Leave”). My role as CFO and Officer of Gentex will end on May 17, 2013. From May 17, 2013 through May 17, 2014 I will receive full salary and benefits. From May 18, 2014 through December 31, 2014 I will receive a monthly consulting fee as a part-time employee of $2,500 per month. While on Administrative Leave my title will be Financial Consultant, and I agree to be reasonably available to be contacted for Information regarding company needs on an as-needed basis and as further outlined below.

On December 31, 2014, I will be officially terminated from the payroll system. 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 agree that I will forfeit my currently accrued vacation time, and while on Administrative Leave I will not accrue additional vacation time. Additionally, I understand that my medical coverage will continue through May 17, 2014 on the same basis as an active employee of Gentex, as Gentex’s plans and practices may be amended from time to time.

All vested stock options must be exercised on or before the Close of business on December 31,2014, or they will be forfeited. I understand that I must adhere to Gentex blackout periods and abide by Gentex’s policies on refraining from trading on insider information. I understand that my December 27, 2012 restricted stock grants will be forfeited upon the signing this agreement. I understand that I will receive a cash incentive bonus of $76,120 for the equivalent prorated share of my 7,500 shares restricted stock grant (Issued on December 27, 2012 and pro-rated through December 31, 2014) equaling 3,017 shares. The prorated share value of $76,120 was calculated based on $25.23 per share times 3,017 shares. This amount will be paid on or around January 8, 2015, subject to the fulfillment of my obligations under this agreement. This $76,120 payment and future restricted stock and stock option exercises between now and December 31, 2014 are subject to the fulfillment of my obligations under this agreement and the 4 year claw back provision the same as my previous 4 years of stock option and restricted stock compensation-totaling $548,744.50. I further agree that the monies I have received under this Section are conditioned on me, within 21 days after my Separation Date, signing, delivering to Gentex, and not revoking a Supplemental Release and Waiver of Claims, essentially identical to the release and waiver set forth in Section 8 below.

(a) I agree to abide by the confidentiality and non-compete provisions in the attached Employment Agreement, signed by me, on November 2, 1993, as well as the daw-back provisions in Gentex’s Grant Agreements (for restricted non-qualified stock options) that governed my stock options during my employment and will govern my stock options during my Administrative Leave (collectively “Prior Agreements”). In addition, during the period of my Administrative Leave, I agree to remain available at reasonable times for reasonable and customary. consultation with Gentex with respect to transitional matters, including but not limited to resigning from my role in EC Aviation as well as the boards of any Gentex subsidiaries and other Gentex-related roles, and to provide reasonable assistance in matters with which I was involved prior to May 17, 2013. Gentex agrees to provide me access to Gentex files as necessary to provide such consultation.

(b) I agree that I will protect Confidential Information, as defined herein, and that i will never, directly or Indirectly, use or disclose it unless specifically authorized by Gentex, except as required by law, governmental regulations, or pursuant to an order of a court or governmental agency, and provided that nothing set forth in this Agreement shall be construed to restrict either party’s cooperation with any governmental investigation. For the purposes of this Agreement, “Confidential Information” means any and all information of or about or related to Gentex, its Affiliates (as defined below), and any of their respective officers, directors, shareholders or employees that was acquired by me as a result of my employment with Gentex and is not generally available to the public.

For the purposes of this Agreement, “Affiliates” means all persons and entities directly or indirectly controlling, controlled by or under common control with Gentex, whether control may be by management authority, equity interest or otherwise. Gentex likewise agrees that it will not disparage me.

(f) If any court determines that any of the provisions of subsections (d) and (e) above are invalid or unenforceable, the remainder of such provisions shall not be affected thereby and shall be given full effect without regard to the invalid provisions. If any court construes any of the provisions of subsections (d) and (e) to be unreasonable because of the duration of such provision or the geographic or other scope thereof, such court shall have the power to reduce the duration or restrict the geographic or other scope of such provisions and enforce such provision as so reduced or restricted.

During and subsequent to the Administrative Leave, Gentex shall Indemnify me to the extent permitted by my Indemnity Agreement and by applicable law, against all costs, charges and expenses, including, without limitation, reasonable attorney’s fees, incurred or sustained by me in connection with any action, suit or proceeding (including Internal investigations by Gentex) to which I am made a party by reason of having been an officer or employee of Gentex. In such action, suit or proceeding, I shall be represented by counsel selected by me and approved by Gentex, such approval not to be unreasonably withheld.
