NewMarket Technology Inc. Updates Homeland Security Strategy; Defense Technology Inc. Announces New CEO Russell Medina

      NewMarket and Defense Technology to Concentrate on Homeland
 Security Solutions for Municipalities and Developing Economic Allies

   NewMarket Technology Inc. (OTCBB:NMKT) today announced that its
affiliate Defense Technology Systems Inc. (OTCBB:DFTS) has appointed
Russell Medina as the new Chief Executive Officer. Mr. Medina's
appointment represents another landmark event in Defense Technology's
rebuilding and repositioning as a Homeland Security Innovator. Mr.
Medina will also join the Defense Technology Board of Directors.
   Mr. Medina has consulted with NewMarket Technology Inc. over the
last two years and was instrumental in the development of NewMarket's
Homeland Security strategy that led to the combination of NewMarket
and Defense Technology's Homeland Security operations earlier this
year. Revenue from this acquisition will be reflected in Defense
Technology's upcoming Annual Report filing.
   Mr. Medina brings a wealth of defense industry experience to the
Company as a retired career Army Officer and graduate of the United
States Military Academy at West Point, N.Y. His distinguished military
career is highlighted by his experience procuring special systems for
various projects with the Department of Defense (DoD) that included
integration with all military services, as well as other government
agencies. His military experience in battlefield communications led
him to a successful post-military telecommunications career
concentrated in the introduction of new products and services. Mr.
Medina has CEO experience with an emphasis in early financing of new
business ventures.
   "Mr. Medina is the right choice to lead Defense Technology
Systems' repositioning as a Homeland Security Innovator," said Dan
McPhee, the outgoing CEO. "His military systems experience combined
with his background in high growth new ventures is the right set of
skills to lead Defense Technology in its next stage of development and
growth."
   "I am excited to join Defense Technology's team," said Mr. Medina.
"The terrorist threat has changed defense strategies and the defense
system requirements to support new strategies. A need for a nimble
defense technology innovator has arisen. The Defense Technology team
has identified and repositioned for that need. I have the good fortune
of coming into a business already poised for rapid growth."

   About Defense Technology Systems, Inc.

   The Company has recently implemented a revitalization and
redirection plan to leverage its experience in providing digital
communication infrastructure solutions to Fortune 1000 companies and
expand into providing overall Homeland Security solutions to major
metropolitan municipalities. To accelerate the plan, Defense
Technology earlier this year acquired a majority interest in an
established defense engineering firm with 20 years of experience and a
portfolio of proprietary technologies. The acquired company is a
leading edge technology company specialized in engineering hardware
and software solutions when commercial-off-the-shelf (COTS) products
do not fulfill the critical requirements of enterprise, military or
government organizations. In the acquisition, Defense Technology also
established a strategic equity partnership with NewMarket Technology
Inc. (OTCBB:NMKT) expected to accelerate organic sales growth of
Defense Technologies products. Management intends to expand its
Homeland Security product portfolio through further acquisition. For
