Spectrum Sciences & Software Holdings Safe-Borders Presentation at Recent Homeland Defense and Security Conference Attracts Interest from Investors and Media as Border Security is Addressed as Major Challenge

POINT ROBERTS, Wash., April 07, 2004 - www.homelanddefensestocks.com, is pleased to announce that the March 30th Investment Opportunities in Homeland Defense and Security Conference presentation for Spectrum Sciences & Software Holdings Corp. (OTCBB: SPSC) is available in PowerPoint and will be available in audio shortly for investors and industry to review. The Spectrum presentation was one of the best attended of the twelve public companies and five industry speakers that educated investors, media and industry analysts at the conference on the long-term prospects and potential of the homeland security industry. Spectrum presented Safe-Border, a contiguous border surveillance product to an audience of media, investment and industry peers.

“Safe-Borders will be marketed at a significant cost advantage to competing technologies,” stated Mr. Steve Cook, V.P., who presented on behalf of the Company. Mr. Cook was interviewed by well-known news radio shows at the conference.

Safe-Borders is an innovative concept for border security and control developed by Spectrum. Safe-Borders will provide government and commercial entities with an affordable capability to control, monitor or survey large geographic regions and/or high value assets. The military defines this capability as a Command, Control, Intelligence, and Surveillance & Reconnaissance (C2ISR) system. The Safe-Borders C2ISR capability will integrate existing and proven technologies thereby reducing program risk and system life-cycle costs and attendant affordability. At the heart of the Safe-Borders C2ISR system is the Safe-Range software application and the "footprint" technologies developed by Spectrum. Safe-Range technologies have been in use by the United States and foreign military services for close to 20 years and will provide the software architecture and footprint modeling technologies required for the Safe-Borders C2ISR system.
