Business Editors

CLIFTON, N.J.--(BUSINESS WIRE)--Dec. 1, 2003

Companies will Develop a New Generation of Security Access Systems

and Cards for the U.S. Air Force and Department of Defense

ECSI International, Inc. (ECSI), a division of Electronic Control Security Inc. (OTCBB: EKCS), has signed an agreement with California-based Applied DNA Sciences, Inc. (OTCBB: APDN), a provider of proprietary embedded-DNA security applications, as a Value Added Reseller (VAR) for product enhancement and distribution. Once the Government publishes the accepted technology in its technical and operational manuals, all Department of Defense agency sales can commence and commissions to ECSI will be 2.5% of net revenue. ECSI is recognized as a leader in force protection and perimeter security and an effective quality provider for both the Department of Defense and the Homeland Security programs. The Force Protection Program office of the U.S. Air Force accepted proposals for multiple award contracts in support of the Integrated Base Defense Security System program (IBDSS) in June of this year. The government has awarded four multiple award contracts (two full open contracts and two small business set asides). ECSI was awarded one of the small business set aside contracts.

ECSI will collaborate with Applied DNA Sciences to develop a new generation of embedded DNA card access control systems for their market sectors. The anti-counterfeit card Access System is an award winning, state-of-the-art biotechnology system comprised of the Applied DNA(TM) Chip and Applied DNA(TM) Access Control Chip Reader. The system controls and prevents individual and corporate identity theft and unauthorized intrusion. The Applied DNA Chip provides a technological innovation in which combinations of plant DNA are embedded into a non silicon-based microchip using a proprietary technique.

"We are very impressed with Applied DNA Sciences' advanced embedded-DNA technology, and look forward to enhancing their products for the IBDSS program and our existing distribution networks," said Arthur Barchenko, chief executive officer of ECSI International, Inc. "It's challenging for emerging companies to develop fully proprietary technology and then take it to the government sector."
