LOS ALAMOS, N.M., May 11, 2000 In response to queries from a number of investors, Manhattan Scientifics, Inc. (OTC Pink Sheets: MHTX) said today that its Los Alamos-based laboratory has so far been unaffected by the Cerro Grande fire that has swept through part of the city.

CEO Marvin Maslow said, "All of our people are safe and have evacuated the town along with the other 11,000 residents. Work in our lab has been halted until it is safe for our people to return to the area. Our computer files, work logs and essential tools have been protected in fireproof safes. The laboratory is located on the extreme eastern edge of Los Alamos. The fire damage has been primarily on the western and northern sides of the town. We will continue to keep our shareholders posted on this matter."

Manhattan Scientifics is developing its MicroFuel Cell™, its holographic storage system and its nanoporous water filtering technologies at the laboratory.

The company announced earlier this week that it has received a contract from the U.S. Army to design and build a fuel cell power source to be used in an Army test program. The program is to evaluate the feasibility of battery replacement in certain types of portable communication equipment now in use by the Army. The fuel cell will be based on Manhattan Scientifics' unique proprietary mid-range power technology (2 watts to 3 kilowatts) developed by the company's NovArs unit in Passau, Germany. If the Army elects to order production quantities of the new fuel cell, the company will decide to either supply the new power source itself through contract manufacturing or to license to a manufacturing partner.

Manhattan Scientifics, Inc. is developing and commercializing proprietary technologies in the advancement of consumer and commercial electronics including MicroFuel Cell technology and holographic media for data storage and Internet-based image management. The Company is also developing nanoporous polymer filtering technologies. Manhattan Scientifics' research headquarters are located in Los Alamos, NM. Executive offices are in New York City.
