Biodefense Mobilization Conference

TULSA, Okla.--(BW HealthWire)--April 4, 2002

Centrex, Inc. (OTCBB:CNEX) today announced that it has been invited to participate in the Biodefense Mobilization Conference to be held in Seattle, April 9-11, 2002.

The Conference is the largest bioterrorism/biodefense conference ever held in the United States. The Company will also attend the pre-conference biotechnology workshop on April 8th which will outline the profound changes being wrought by this new and rapidly growing biodefense industry.

Principle topics to be addressed at the conference include potential bioweapon agents and biodetectors, disaster preparedness, community planning, facilities hardening, mail room security, responder training, legal issues including public safety and civil liberties, communication networks with a focus on inter-agency communication, fear management featuring catastrophe reporting and the media, and academic and applied research.

"Having the knowledge of how to manage a bioterrorism catastrophe is not enough to win the war on terrorism," said Thomas R. Coughlin, Jr., MD, CEO of Centrex. "We must actively work to develop these advanced technologies into products that will become powerful weapons to mitigate the effects bioterrorism. Centrex is developing a system designed to provide early detection of bioterrorism agents, so that swift countermeasures can be taken and lives saved."

The Biodefense Conference is also a multidisciplinary forum intended to provide biodefense vendors and researchers with the opportunity to present their devices, services and innovations. Vendors with both current products and systems under development will be brought together in one place in exhibits and discussion forums that allow for thorough comparisons and the exchange of ideas.

Centrex owns the exclusive worldwide license to develop, manufacture, and market a system for detecting microbial contamination in air, food, and water. The detection system, currently in development, is designed to be adaptable and is easily tailored to detect a variety of bacterial or viral organisms by recognizing the unique DNA fingerprint of the organism. Since the September 11th attacks and the subsequent bioterrorism attacks through the U.S. mail, the Company has expanded its mission to include the development of technology for the rapid detection of potential bioterrorism agents. The organisms being considered for detection by the prototype device include all those named in the validated threat list published by the Defense Intelligence Agency, in addition to several other potential biowarfare agents. The proposed device is a simultaneous multi-channel detection system that is compact, fully automated and capable of monitoring the presence of biological agents in air, food, and water.

The Centrex website, listed below, also contains many useful links on bioterrorism some of which are quite technical in content and provide access to bibliographies, Internet resources, journal articles, government documents, education, and training materials on bioterrorism. The Company hopes that the availability of these links will help educate site visitors on the bioterrorism threat and provide answers to some common questions.
