EDEN Bioscience Corporation, which develops, manufactures and markets innovative, natural protein-based products for improving crop production and protecting plants, today announced financial results for its second quarter ended June 30, 2003.

Net revenue for the second quarter of 2003 was $549,000, which compares to net revenue of $1.1 million in the second quarter of 2002. Revenue is derived solely from sales of Messenger to distributors. Net loss in the second quarter was $3.3 million, or $0.14 per weighted average common share, compared to a net loss of $4.7 million, or $0.19 per weighted average common share in the second quarter of 2002. Per-share loss amounts for the quarter are based on weighted average common shares of 24.3 million in 2003 and 24.2 million in 2002.

The company estimates that distributors sold approximately 264,000 ounces of Messenger to growers in the second quarter of 2003, compared to approximately 324,000 ounces in the same period in 2002. For the first six months of 2003, the company estimates that distributors sold approximately 422,000 ounces to growers, compared to approximately 468,000 ounces in the same period in 2002. Based on preliminary information, EDEN estimates that 564,000 ounces of Messenger remained in distributors' inventories on June 30, 2003.

"While total estimated ounces used by growers is down, we estimate grower usage of Messenger in our high value focus crops is flat year-to-date when compared to 2002 usage. Comparing focus crops, we estimate usage has increased in strawberries, citrus, melons, peppers, and table grapes. These gains have been offset by decreased usage in cherries and tomatoes resulting from unfavorable weather conditions at fruit set and planting time, respectively," said Rhett Atkins, President and CEO. "We believe that grower usage of Messenger will continue in our focus crops in the second half of 2003 and that this usage will be primarily filled from current distributors' inventory. As a result of current channel inventory levels, and given the seasonality of our targeted crops, we expect our sales and distributor sales to growers in the third quarter of this year to be minor. We believe that under some of the most adverse weather conditions in memory we have extended our gains in a majority of our focus crops and have the follow-up plan in place to demonstrate performance and accelerate future sales. This has been accomplished using considerably less resources than in past years."

Cash and investments as of June 30, 2003 totaled $23.8 million, compared with $26.1 million at March 31, 2003.

EDEN Bioscience is a plant technology company focused on developing, manufacturing and marketing innovative, natural protein-based products for agriculture. EDEN Bioscience believes its technology and initial product, Messenger, provide growers with a new tool to improve crop production and plant protection. Messenger is based on naturally occurring proteins called "harpins," which activate a plant's intrinsic ability to protect itself through growth and stress-defense responses. These responses enhance overall plant health, improve plant vigor and stamina, and result in improved crop quality, yield, and/or shelf life.
