Spectrum Sciences Announces William Ham as President and Chief Executive Officer

FORT WALTON BEACH, Fla., Mar 31, 2004 - Spectrum Sciences and Software, Inc. (SPSC), highly focused on homeland security through the provision of full-service, quality solutions to complex and diverse government initiatives, today announced the appointment of William Ham, a long standing company veteran and Executive Vice-President in charge of Range Systems Operation and Management-Gila Bend, as President and Chief Executive Officer. Mr. Ham, a graduate of the United States Air Force Academy joined Spectrum after 20 years service, having earned a BS degree in Electrical Engineering. Mr. Ham, outlined Spectrum's next-generation vision for the Company pursuant to initiatives approved today by Spectrum's Board of Directors. Among the initiatives the Board approved yesterday, is a directive calling for a highly proactive program for the acquisition of strategic companies and assets on an accretive basis to support significant contributions in revenues. The expanded vision is coupled to the Company's long-standing commitment to aggressive organic growth.

"These actions by Spectrum's Board of Directors bode well for the Company and our shareholders, with the dual directives of aggressive growth through accretive acquisitions, and a reenergized commitment to organic growth, we reaffirm our commitment to market expansion and continued successful financial performance," stated Mr. Ham. "This successful performance was most recently rewarded by the Company achieving its all time highest share price today in one of the top ten highest volume days in the Company's history. The performance is also demonstrated by the Company's record-breaking third quarter revenues of $3.2 million, and record nine months revenues of approximately $10 million. Which marked the most significant financial achievement in our 20-year history and is further reinforced by the numerous recent positive corporate developments. These new initiatives will continue to fuel our present success, while building a strong foundation for our future".

Mr. Ham concluded, "Spectrum's long-standing position as a favored defense vendor, coupled with our ongoing positive financial performance, provides a solid foundation for our expanded commitment to aggressive growth with a new focus on accretive or earnings- generating acquisitions. Quite simply, the Board determined the criticality of capitalizing on the immediate and significant opportunities available to the Company through the broad array of Homeland Security programs being deployed by the United States government. This is in addition to the expanded demand for defense-related solutions internationally as the result of unrelenting and undiminished worldwide terrorist threats. The Company's favorable position within the industry and our continued development of sophisticated, dependable and cost-effective solutions will continue to propel our growth. Our business model is clearly effective and tuned to deliver competitive advantages, improved earnings and, substantially increased shareholder value."

Other Spectrum Developments
The Company also noted that Steve Cook, Spectrum's Vice President of Investor Relations, presented at the Homeland Defense Show in Washington, D.C. The presentation, at the National Press Club, included the attendance of members of the international press corps.

"The presentation today at the prestigious National Press Club was attended by many of the "Who's Who" of the defense community," stated Mr. Cook. "We were pleased by the substantial number of media inquiries Spectrum received, including an interview with CBS Marketwatch, which we believe may have contributed to today's significant volume, representing one of the highest volume days in the Company's history with an all time high for our share price. I am also pleased to note the great response that Spectrum generated on March 23rd at FOSE 2004 Government IT trade show in Washington, D.C where the Company premiered the first public demonstration of the Safe-Borders next generation technology."
