Defense Technology Systems, Inc. Announces Plan To Acquire Homeland Security Operations of NewMarket Technologies.

HAUPPAUGE, N.Y. -- NewMarket CEO Philip Verges To Be Added To Defense Technology Board

NewMarket Technology, Inc (OTCBB:NMKT) and Defense Technology Systems (OTCBB: DFTS) today announced a Letter of Intent to combine their respective Homeland Security businesses under Defense Technology Systems in a transaction under which Defense Technology will acquire a majority interest in NewMarket Technology's Homeland Security subsidiary. As part of this transaction, NewMarket CEO Philip Verges will join the Defense Technology Systems Board of Directors.

"NewMarket's proprietary Homeland Security technology is impressive and very complimentary to our current product line," said Daniel McPhee, CEO of Defense Technology. "This combination is an important step in our continuing plan to build a comprehensive unique Homeland Security product line through the acquisition of additional proprietary Homeland Security technology companies. Adding Philip Verges to our board, given his success at NewMarket building proprietary technology portfolios through acquisition, we believe will accelerate our ability to build a robust Homeland Security product line. We believe Mr. Verges' background and contacts as a graduate of the United States Military Academy at West Point will also benefit DTS. We anticipate finalizing the transaction and releasing more details to the shareholders of both companies to include 2005 financial forecasts."

"Defense Technology has begun to assemble a compelling Homeland Security product line and we believe our Homeland Security operation will add a number of proprietary technologies that accelerate the overall development of a unique Homeland Security offering," said Philip Verges CEO of NewMarket. "Our Homeland Security business has developed well over the past year winning a number of million dollar defense subcontracts and city government contracts. Within a dedicated publicly listed Homeland Security operation, I am confident that the combination of our Homeland Security business with DTS will result in increased growth in 2005."
