Vitens, leading Dutch utility, to lease BioSentry Water Monitoring System from company's distributor

SAN DIEGO, March 19, 2007 -- JMAR Technologies Inc. announced today that it has received a purchase order from Interline Systems BV, a JMAR distributor that will install and lease the BioSentry™ Water Monitoring System to Vitens, a leading Dutch water utility that serves approximately 5.4 million consumers. The order comes just six weeks after the company received an order from Yorkshire Water Services Ltd., a leading water utility in England. This test program marks the second water utility application for BioSentry in Europe. Vitens will lease the BioSentry System for an evaluation period of six months. Upon successful completion of the test period, it will have the option to purchase the unit for permanent installation.

The initial installation at Vitens will determine the effectiveness of the BioSentry in detecting pathogenic bacteria such as E-Coli and Legionella that can contaminate water distribution systems. BioSentry is part of a Vitens' initiative to develop a complete water security monitoring system inclusive of chemical and biological agents.

"BioSentry is a key component of water contamination monitoring as it's the only biological detection system that provides on-line, real-time results," said Wouter van Delft, project leader of Vitens. "Throughout Europe, waterborne pathogen events are becoming more and more prevalent and BioSentry can help to identify the presence and behavior of microorganisms in the water treatment and distribution processes."

"We are excited to receive another order from a major European water utility so quickly after receiving the initial purchase order from Yorkshire Water," stated Neil Beer, JMAR's President and CEO. JMAR has BioSentry Systems installed in the beverage quality assurance, water utility operations, cruise ship water monitoring, and homeland security markets. In addition, the system is being tested by the U.S. Environmental Protection Agency for homeland security applications.

JMAR Technologies, Inc. is a leading innovator in the development of laser-based technology and x-ray processes for nano-scale imaging, analysis and fabrication. The company is leveraging more than a decade of laser and photonics research to develop a portfolio of products with commercial applications in rapidly growing industries, while continuing to carry out research and development for the U.S. Government.

JMAR's leading commercial product, BioSentry, is a contamination warning system for waterborne microorganisms. BioSentry uses laser-based, multi-angle light scattering technology to provide continuous, on-line, real-time monitoring for harmful microorganisms. BioSentry is targeted toward a number of applications across multiple markets, including homeland security, the cruise ship and beverage industries, pharmaceutical companies, and municipal water utilities.

JMAR's pursuit of leading edge products targets nanotechnology, bioscience and the semiconductor industries with its BriteLight™ laser, a stand-alone product as well as the x-ray light source in nanolithography systems; the X-ray Microscope for 3D visualization of single cells and polymers; and the X-ray NanoProbe for enabling nano-scale interaction, analysis and materials modification. In addition, JMAR employs key strategic alliances for the production of a hazardous materials chemical sensor, and the prototyping and production of a nanoparticle ultra-thin coating system.
