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 third quarter ended September 30, 2002.

Revenue for the third quarter of 2002 was $60,000, which compares to revenue of $439,000 in the third quarter of 2001. Revenue is derived solely from sales of Messenger(R) to distributors. Net loss in the third quarter was $4.7 million, or $0.19 per weighted average common share, compared to a net loss of $5.9 million, or $0.25 per weighted average common share in the third quarter of 2001. Per-share loss amounts for the quarter are based on weighted average common shares of 24.3 million in 2002 and 24.0 million in 2001.

"We are pleased with the progress we've made in our targeted crops this season," said Rhett Atkins, president and CEO. "While total estimated distributor sales to growers have increased just 9% through September, distributor sales to growers in our targeted crops have increased significantly, reflecting the changes we made earlier in the year to focus our marketing efforts on higher-value crops such as grapes, tomatoes, peppers, melons, and citrus. We are pushing hard to ensure that extensive follow-up is made with growers and distributors on all research and commercial field plots to build a strong foundation for continued Messenger adoption and sales for the growing seasons in 2003 and 2004." Atkins, who has more than 27 years of experience in strategic marketing and sales of agricultural
products, joined EDEN Bioscience as president and CEO on June 24, 2002.

The company estimates that distributors sold approximately 143,000 ounces to growers in the third quarter of 2002, compared with 261,000 ounces in the third quarter of 2001. In total for the first nine months of 2002, the company estimates that distributors sold approximately 611,000 ounces to growers, compared with 561,000 ounces in the first nine months of 2001. Based on preliminary information, EDEN estimates that 882,000 ounces remained in distributors' inventories on September 30, 2002, compared with an estimated 1,009,000 ounces in distributors' inventories at June 30, 2002.

"From a financial perspective, we further trimmed our operating costs to aggressively manage our cash position during the quarter, as we continued to reduce our channel inventory," said Brad Powell, Chief Financial Officer. "While we expect grower usage of Messenger to continue for the remainder of 2002, those orders will most likely be filled from current distributor inventory. As a result, we expect our sales to distributors in the fourth quarter to be minor."

Cash and investments as of September 30, 2002 totaled $34.9 million, compared with $37.7 million at June 30, 2002.
