LANSING, Mich., July 6, 2005 – Neogen Corporation (NASDAQ: NEOG) today announced it has signed an agreement with Brussels, Belgium-based UCB (Euronext Brussels) to acquire UCB’s dairy antibiotic testing business. Closing is expected to take place late in the 2005 calendar year.

UCB’s dairy antibiotic testing products present a strong complementary fit with other testing products that Neogen offers the dairy industry, including an ATP sanitation monitoring system, water quality test, food allergen tests, and bacteria tests. Considerations for the acquisition include $14.7 million (U.S.) in cash, and potential future performance-based compensation.

“Dairy antibiotic testing products have been on our radar screen for many years because of their synergistic fit to our business,” said James Herbert, Neogen’s President. “This transaction comes at a time and price that makes good sense for both of our companies. We look forward to adding UCB’s exceptional antibiotic tests to our product line, and introducing UCB’s customer base to our comprehensive group of products.”

Sales of UCB’s dairy testing products approximated $9 million (U.S.) in its most recent fiscal year, of which over 90% represented sales outside North America. Beta Star, one of UCB’s key dairy antibiotic testing products, does not yet have FDA approval for sale to the large dairy market in the United States, but that approval is being pursued. Milk processors typically test raw milk arriving from dairy farms for antibiotic residues.

Products involved in the acquisition include the widely-used Penzyme product, and the newer technology Beta Star test. The Beta Star test uses a format nearly identical to Neogen’s simple dipstick tests for mycotoxins, food allergens, and ruminant by-products.
