EDEN Bioscience Corporation (Nasdaq:EDEN), which develops, manufactures and markets innovative, natural products for improving crop production and protecting plants, today announced
the resignation of Jerry Butler, President and Chief Executive Officer and a member of the board of directors, effective immediately.

Butler has served as President, CEO and a member of the board since EDEN was incorporated in July 1994.

EDEN's board of directors named Bradley S. Powell, VP and Chief Financial Officer, as acting President while the company conducts a search for Butler's replacement. Powell has served as EDEN's CFO since July 1998. The board also promoted Dr. Zhongmin Wei to the new position of Chief Scientific Officer. Dr. Wei has served as VP of Research since May 1998.

"We greatly value Jerry's many contributions to EDEN Bioscience(R) and thank him for helping the company get to its current stage of development," said Dr. William Weyerhaeuser, chairman of EDEN's board of directors. "Jerry has played a significant role in building this Company's technology platform, and we wish him all the best in his future endeavors. We are confident that
as we begin the search for a new President and CEO, Brad's and Zhongmin's experience will enable EDEN to continue to drive forward in its growth cycle." The Company expects to record a $480,000 charge in the fourth quarter of 2001 related to Mr. Butler's employment agreement.

Mr. Butler said, "I feel blessed to have been a part of EDEN's successes in bringing this technology forward from a scientific discovery to a commercial product that we believe will provide significant benefits to agriculture. I wish Brad, Zhongmin and the entire EDEN team every success as they build upon the foundation I am leaving."

EDEN Bioscience is a plant technology company focused on developing, manufacturing and marketing innovative natural products for agriculture. EDEN believes its technology and initial product, Messenger, allow it to offer superior alternatives to existing crop yield enhancement and plant protection products in terms of both performance and safety and, importantly, to avoid the substantial public resistance to many chemical pesticides and genetically modified plants. Messenger, which received EPA approval for full commercial use in April 2000, is based on naturally occurring proteins called "harpins," which activate natural plant defense systems to protect against disease and pests, and simultaneously activate plant growth systems, improving crop yield and quality. It has been extensively tested in hundreds of field trials in four countries and on more than 40 crops including: citrus, cotton, strawberries, tomatoes, peppers, melons, wheat, rice, corn, peanuts, tobacco, grapes and others. EDEN Bioscience's headquarters are at 3830 Monte Villa Parkway, Bothell, WA 98021, (425) 806-7300; www.edenbio.com.
