AgriBioTech Inc. and Mycogen to Develop Insect-Resistant Alfalfa Using Bt Technology.

LAS VEGAS--(BUSINESS WIRE)--Sept. 21, 1998--Dr. Johnny R. Thomas, chairman and chief executive officer, AgriBioTech Inc. (Nasdaq/NM:ABTX), Monday announced that AgriBioTech and Mycogen (Nasdaq/NM:MYCO) have signed a letter of intent to jointly develop insect-resistant alfalfa varieties.

Insect-resistant alfalfa varieties will be marketed to capture the added value expected to result from higher yields, increased stand persistence and enhanced nutritional value. AgriBioTech and Mycogen will share equally the captured incremental value added under the terms of the exclusive license. AgriBioTech and Mycogen have also agreed to priority negotiations on insect-resistant turfgrasses utilizing Bt technology.

Mycogen will be responsible for screening its Bt gene and strain library in order to identify genes active against the insect pests targeted by AgriBioTech. Mycogen will provide AgriBioTech with the selected genes in an expression cassette ready for transformation into alfalfa.

"Matching Mycogen's Bt insect-resistant technology with AgriBioTech's industry-leading alfalfa and turfgrass breeding and marketing capabilities will be good for both companies and our customers," said Mycogen President Carl Eibl.

"Over the long term, Mycogen will have an opportunity to generate significant revenue from our participation in the value added to AgriBioTech's seed products, and we will also be able to market jointly developed insect-resistant alfalfa seed under the Mycogen brand."

AgriBioTech will be responsible for all transformation, regeneration, selection conversion and breeding activities. AgriBioTech will utilize its germplasm for all breeding activities and will be primarily responsible for marketing the insect resistant varieties. Mycogen will also market product through its distribution channels.

According to Dr. Tom Rice, vice president and director of research for AgriBioTech, "Insect resistance is a priority target based upon the value it will bring to our customers. AgriBioTech is pleased to combine its emerging biotechnology capability, its leading germplasm position and its industry-leading market share with Mycogen's exceptional Bt technical capabilities and intellectual property."

AgriBioTech is a fully integrated full-service seed company specializing in the forage and turfgrass seed sector, complete with research and development of proprietary seed varieties, seed processing plants, and a national and international distribution and sales network.

The company has completed 32 acquisitions since Jan. 1, 1995, and is the largest forage and cool season turfgrass seed company in the world, with a current level of annualized net sales of approximately $445 million.
