OTHER EVENTS. On January 20, 1997, the Registrant issued a press release regarding USDA approval of the Registrant's bursal disease vaccine and fourth quarter earnings. The text of the press release follows: FOR IMMEDIATE RELEASE IN OVO INFECTIOUS BURSAL DISEASE VACCINE APPROVED BY USDA; WRITE-OFF IMPACTS 4TH QUARTER EARNINGS, FULL YEAR REMAINS PROFITABLE RESEARCH TRIANGLE PARK, N.C., Jan. 20, 1997 -- Embrex Inc. (Nasdaq: EMBX) today announced it has received U.S. Department of Agriculture (USDA) approval for its new viral neutralizing factor-based vaccine for Infectious Bursal Disease (IBD or Gumboro Disease) in broiler chickens. The approval is specifically for in ovo (in-the-egg) administration of the vaccine complex via Embrex's patented INOVOJECT(R) egg injection systems. Trade-named Bursaplex(TM), this new vaccine (previously called BDA-Blen) is a unique combination of an existing strain of IBD vaccine and Embrex's patented Viral Neutralizing Factor (VNF) licensed from the University of Arkansas. VNF has been shown to render a virulent infectious bursal disease vaccine both safe and effective in broiler chickens, thus allowing its use at or before hatch. Some of the health benefits of this new VNF/vaccine complex include single-dose efficacy and effective early vaccination in broilers. Currently, 80 percent of the broiler chickens raised in the United States and Canada receive certain in ovo vaccines via the INOVOJECT(R) , an egg injection system which eliminates the need for manual vaccination after hatch. "During 1997, we look forward to collaborating with the poultry industry to demonstrate the clear health and economic advantages of administering Bursaplex(TM) in ovo to prevent infectious bursal disease in broiler chickens and to gaining market acceptance of Bursaplex(TM) during the second half of 1997 and into 1998," Embrex President and Chief Executive Officer Randall L. Marcuson said. The Disease Infectious bursal disease weakens a chicken's immune system, resulting in poor growth and the potential for contracting other diseases. The disease is widespread in the United States, Northern Europe and Asia. To date, IBD has been treated post-hatch via manually delivered vaccines or in drinking water. This $40 million worldwide vaccine market is growing 10 percent annually. Existing vaccines are associated, however, with certain limitations. For example, some vaccines cannot be used safely or effectively in ovo. "USDA's approval of Bursaplex(TM) is significant because it validates the second element of our corporate strategy: to commercialize highly valued in ovo products that can effectively and safely be delivered to broilers through our INOVOJECT(R) egg injection system. Next, we will begin the regulatory approval process for Bursaplex(TM) in selected Latin American and Asian markets," said Marcuson. -2- Fourth Quarter Write-Off Embrex also indicated that a one-time fourth-quarter write-off of approximately $160,000 as a result of certain obsolete materials will create a loss for the fourth quarter. The full year remained profitable and, without the write-off, fourth-quarter operations would have been profitable. Full financial results for the fourth quarter and 1996 year end are expected to be reported in mid-February. Embrex, Inc. has developed and commercialized the INOVOJECT(R) system, a proprietary, automated, in-the-egg injection system which eliminates the need for manual vaccination of newly hatched broiler chicks. Embrex is also developing and marketing patented pharmaceutical and biological products to improve bird health, reduce bird production costs and provide other economical benefits to the poultry industry.
