             GENTEX PLANS FOR RETIREMENT OF CHIEF FINANCIAL OFFICER

         ZEELAND, Michigan, February 21, 2006 -- Gentex Corporation, the
Zeeland, Michigan-based manufacturer of automatic-dimming rearview mirrors and
commercial fire protection products, today reported that the Company's Chief
Financial Officer and Vice President - Finance, Enoch Jen, has provided notice
of his intent to retire effective January 2, 2007.

         "Enoch is a longtime, highly valued associate at Gentex," said Gentex
Executive Vice President Garth Deur. "He has been open about his plans to retire
in this timeframe for a number of years. We offer him our best wishes as he
plans his future."

         Deur said that the Company expects to name Steven Dykman, currently the
Company's Treasurer and Director of Accounting and Finance, to succeed Mr. Jen
upon his retirement. To assist in an orderly transition, Mr. Jen has agreed to
work as a consultant to the Company part time during calendar year 2007.

           Founded in 1974, Gentex Corporation (Nasdaq: GNTX) is an
international company that provides high-quality products to the worldwide
automotive industry and North American fire protection market. Based in Zeeland,
Michigan, the Company develops, manufactures and markets interior and exterior
automatic-dimming automotive rearview mirrors that utilize proprietary
electrochromic technology to dim in proportion to the amount of headlight glare
from trailing vehicle headlamps. Many of the mirrors are sold with advanced
electronic features, and approximately 95 percent of the Company's revenues are
derived from the sales of auto-dimming mirrors to nearly every major automaker
in the world.
