Centrex, Inc. (OTCBB:CNEX) today announced that it is co-sponsoring "The Powers That Be" Conference in Washington, D.C. on March 6th & 7th, 2003 in conjunction with the Homeland Security Technology Council (HSTC) of the United States and Healthshore, Inc. The Conference will present policies, programs, and issues of federal opinion leaders in the homeland security arena. It is intended to provide a forum where corporate and federal officials, law enforcement, first responders, government staff, academicians and researchers can discuss the issues surrounding homeland security technologies and some of the major policy issues regarding technology currently being developed to strengthen the security of our nation.

Discussions at the all day event will cover such topics as dealing with the federal government in the homeland security arena, grant and research contract availability, coordinating trans-agency initiatives, procurement processes, issues surrounding technology standards, and policy implications of these new security and defense technologies.

Following the full day conference on March 6th, there will be a half-day business session for members of the HSTC of the United States of which Centrex's CEO, Dr. Thomas R. Coughlin, Jr. is currently acting Director. The members-only session on March 7th will serve to report to the HSTC membership on the Council's series of Washington initiatives and to describe the results of numerous meetings the Council has recently held with top federal officials. Focus of this business session will be on the roles the Council has been asked to play in the new homeland security arena, issuing the Council's first position statement on key issues facing the industry, membership recruitment, and setting the Council's agenda for the upcoming year.

Any organization, company, government agency, or individual having an interest in promoting homeland security through the application of innovative and evolving technologies is invited and should attend the Conference. This especially includes companies focused on telecommunications, computer security, biotechnology, hazardous materials detection, and first responder equipment. Through this broad based industry conference approach, the HSTC hopes to help achieve the President's goals of a stronger coordination between government and the private sector, and increased use of America's intellectual talents and resources to enhance the strength and stability of our nation and reduce our vulnerability to terrorist attacks.

Centrex, Inc. is a development stage company organized in 1998 to identify and commercialize proprietary systems for the detection of biological contaminants in food, air and water. Centrex, Inc. has licensed worldwide rights to all applications of the Single Molecule Detection technology (SMD) currently being developed at Los Alamos National Laboratory (LANL). This technology, one of many emanating from LANL's high tech research, has the potential to provide specific, accurate and very rapid detection of harmful organisms in air, food and water, as well as having other potential applications in DNA and RNA analysis. The initial focus of the Los Alamos program is to complete the prototype for an advanced automated detection system for use in the rapid detection of bioterrorism pathogens such as anthrax, smallpox, plague and other deadly organisms. This initial phase of development is intended to produce a prototype that could be useful in biodefense applications both in the military and civilian sectors internationally. Additionally, the device could be employed commercially in enclosed environments such as mail and parcel delivery service facilities, airplanes, mass transportation centers, and in monitoring the air quality of commercial office buildings.

The HSTC of the United States is an industry organization of homeland security technology business leaders, scientists and public officials whose purpose is to facilitate the adoption of effective homeland security technologies. The Council provides an active forum for technology users, manufacturers, and suppliers to evaluate technologies, develop standards and communicate with government, industry, and the public. Members of the Council seek to improve our domestic security through the application of new and innovative technologies.

Homeland Security Director Tom Ridge has challenged the private sector to take a leadership role in homeland security. Direct involvement in the development of a coherent homeland security strategy through the application of highly advanced and innovative technology is one of the ways the private sector can answer that challenge.
