FOR IMMEDIATE RELEASE

Science Dynamics Subsidiary SMEI Reports Record Order Backlog

Pennsauken, NJ, December 05, 2005 -- Science Dynamics Corporation (OTC Bulletin Board: SIDY), a provider of advanced technological solutions to Department of Defense and executive government agencies, said today that its subsidiary Systems Management Engineering, Inc. (SMEI) has a record contract backlog of $14.6 million.  Revenue under the contract is dependent upon government agencies funding the contract.

The backlog represents the value of existing SMEI contracts over their remaining life. The contracts are for services to be provided. Major contract assignments include Federal Enterprise Architecture (FEA), Defense Enterprise Architecture (DODAC), systems analysis, application support and GIS development for the U.S. State Department, Department of Defense and other commercial and federal clients. Although still  relatively small, the firm is teaming successfully as a prime contractor with national consulting firms, such as Booz Allen Hamilton, and major defense contractors, such as DynCorp.

Paul Burgess, CEO of Science Dynamics, said, “Our business has grown tremendously in the last year. This backlog underscores the value that SMEI brings to our operations. Significantly, much of this backlog is composed of contract extensions that required minimal additional overhead to secure. This demonstrates solid customer satisfaction with our services and provides us with excellent momentum going into 2006.”
