JMAR Concludes NAVAIR Program Technical Review.

-- Summit Review of Contractor's Nanotech R&D Programs --

SAN DIEGO -- JMAR Technologies, Inc. (NASDAQ:JMAR), a leading innovator in the development of laser-based technology and x-ray processes for imaging, analysis and fabrication at the nanoscale, announces a successful review with industry and government representatives of its NAVAIR (Naval Air Systems Command) R&D programs.

The review is held annually to demonstrate the accomplishments of the collective JMAR divisions on tasks ranging from x-ray lithography and x-ray point source systems, to advanced inspection methods and materials development. One co-development project receiving special attention this year was the engineering design of a revolutionary nano-coating system that can be used for high volume thin film coatings in both semiconductor and textile industries. JMAR engineers, scientists and executives were joined by several colleagues and professors from around the world. Some 32 industry leaders in advanced lithography attended the event to contribute in presentation and review on aspects of JMAR's key technologies, many of which complimented the JMAR team on the success of the review.

The three day session included programmatic reviews as well as introduction and assessment of new emerging opportunities available to JMAR for consideration under the following years' contract. At the conclusion of the scheduled presentations, the participants were addressed by Vermont's Lt. Gov. Brian Dubie, a colonel in the reserve forces who maintains a close personal interest in JMAR's technologies. He has seen first-hand the importance of high tech industry on the battlefield as well as for the safety of those here at home.

On the last day of the summit, JMAR demonstrated a continuous run of its newly completed LASER produced plasma x-ray point source for nanolithography in the clean room facility. This work was completed under NAVAIR contract # N00421-02-D-3189. JMAR is most appreciative to Mr. Charles Caposell and Mr. Glenn Marshall of NAVAIR, and Dr. Joe Mangano of DARPA, without whose support this highly lauded scientific and technical review would not have been possible.

About JMAR

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 flagship commercialization product, BioSentry[TM], is a contamination warning system for waterborne microorganisms. BioSentry[TM] uses laser-based, multi-angle light scattering technology to provide continuous, on-line, real-time monitoring for harmful microorganisms. BioSentry[TM] 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[TM] 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.
