EDEN Bioscience Corporation (Nasdaq:EDEN), which develops, manufactures and markets innovative, natural protein-based products for improving crop production and protecting plants, today announced financial results for its first quarter ended March 31, 2002.

Revenue for the first quarter of 2002 was $555,000, which compares to revenue of $2.5 million in the first quarter of 2001. Revenue is derived solely from sales of Messenger(R) to distributors. Net loss in the first quarter was $5.5 million, or $0.23 per weighted average common share, compared to a net loss of $2.5 million, or $0.10 per weighted average common share in the first quarter of 2001. Per-share loss amounts for the quarter are based on weighted average common shares of 24.2 million in 2002 and 23.9 million in 2001.

The company estimates that distributors sold approximately 144,000 ounces to growers in the first quarter of 2002, compared with approximately 91,000 ounces in the same period in 2001. Based on preliminary information, EDEN estimates that 1,039,000 ounces remained in distributors' inventories on March 31, 2002, compared with 1,016,000 ounces in distributors' inventories at December 31, 2001.

"While the economy in many agricultural sectors remains difficult, we have made progress on expanding the use of Messenger," said Brad Powell, interim president and CFO. "Although it is still early in the season, the usage of Messenger is increasing and new users are beginning to adopt the product in their production programs. We continue to manage our expenses responsibly, allowing additional time to further the adoption and sales of Messenger."

Cash and investments as of March 31, 2002 totaled $41.5 million, compared with $48.3 million at December 31, 2001. The company believes this balance is sufficient to fund operations for at least the next 18 months.

EDEN Bioscience is a plant technology company focused on developing, manufacturing and marketing innovative, natural protein-based products for agriculture. EDEN believes its technology and initial product, Messenger, provide growers with a new tool to improve crop production and plant protection. Messenger, which received unconditional EPA approval for full commercial use in April 2002, 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 tested in over 1,000 field trials in many countries and on more than 40 crops including: citrus, cotton, cucumber, peppers, strawberries, tobacco, tomatoes, grapes and corn.
