About U.S. Sustainable Energy Corp.

U.S. Sustainable Energy offers a revolutionary new energy process that creates
three times more fuel per feedstock unit than any other biofuel process. The
company has engineered the first bio-renewable fuel able to serve as a
replacement to diesel, with none of the negative traits associated with
competitive green fuels. The USSEC biofuel is furthermore created at a nominal
cost as the byproduct of producing organic fertilizer from recycled waste
products, a discovery made during research into agricultural biomass now known as
the "Rivera Process." The technology offers a solution to foreign oil dependence,
significant reduction to the cost of electricity and ethanol production, and the
eventual reversal of greenhouse gas emissions.

Management and current operations are focused on leveraging the superior
performance and low cost of the fertilizer, biogas and biofuel within bundled
plant operations, turnkey energy contracts, ethanol production, and other
critical applications that rely on energy as a major cost component. For more
