Guardian Technologies Enters Into R&D Agreement with Federal Transportation Security Laboratory; Federal Lab Will Test Guardian's PinPoint(TM) Threat-Detection Technology.

HERNDON, Va. -- Guardian Technologies International, Inc. (OTCBB:GDTI), a leading provider of high-performance security and healthcare solutions based on "Intelligent Imaging Informatics" (3i(TM)), today announced it has entered into a Cooperative Research and Development Agreement (CRDA) with the federal Transportation Security Laboratory (TSL) to test its PinPoint(TM) threat-detection technology.

Under the terms of the agreement, the TSL will perform an independent assessment of PinPoint, which has been developed to improve the detection of explosives, guns, knives, and ammunition concealed in parcels, boxes, baggage or cargo containers. The PinPoint software is designed to facilitate seamless integration with commercial X-ray equipment and enable security teams to screen more people and baggage with greater accuracy.

The TSL is a branch of the U.S. Department of Homeland Security's Science and Technology (S&T) Directorate, and is located in Atlantic City, NJ, within the Federal Aviation Administration (FAA) William J. Hughes Technical Center.

CRDA programs under the TSL mission are conducted to accelerate and expand promising technologies to the point of operational test and evaluation. Technologies that have successfully gone through this process are typically passed on to the TSA Office of Security Technology for operational evaluation in the nation's airports.

"We are excited by the opportunity to work with the U.S. Government's premier facility for testing and validating cutting-edge transportation security technologies," said Guardian Technologies Director of Business Development John McDaid. "The timing of this opportunity fits well with the DHS Transportation Security Administration recently making explosives detection at the passenger checkpoint one of the agency's top priorities. We are already in discussions with hardware providers and system integrators about getting this technology into deployment as soon as possible, and the TSL program is a critical step in the testing and evaluation process."
