cash outflow. Cash and cash equivalents used during the second quarter of 2003

About Millennium Cell:

Founded in 1998, Millennium Cell is based in Eatontown, NJ, and has developed a
multi-faceted patent portfolio, which the company is pursuing in the United
States and internationally surrounding a proprietary process called Hydrogen on
Demand(. The Hydrogen on Demand( system safely generates pure hydrogen from
environmentally friendly raw materials. In the process, the energy potential of
hydrogen is carried in the chemical bonds of sodium borohydride, which in the
presence of a catalyst releases hydrogen. The primary input components of the
reaction are water and sodium borohydride, a derivative of borax. Borax is found
in substantial natural reserves globally. Hydrogen from this system can be used
to power fuel cells or fed directly to internal combustion engines. Millennium
Cell also has a patented design for boron-based longer-life batteries. For more
