ABOUT SONEX

Sonex  Research,  Inc.,  a leader  in the  field of  combustion  technology,  is
developing its patented Sonex Combustion  System (SCS)  piston-based  technology
for in-cylinder  control of ignition and  combustion,  designed to increase fuel
mileage and reduce  emissions  of internal  combustion  engines.  Sonex plans to
complete development, commercialize and market its SCS Stratified Charge Radical
Ignition  (SCRI)  combustion  process to the automotive  industry in response to
forthcoming  increases in national  vehicle fuel mileage  standards.  Presently,
high mileage, roomy and safe five-passenger  automobiles using gasoline,  direct
injected (GDI) engines are sold only in Japan and Europe due to high  emissions.
Sonex intends to conclusively  demonstrate that SCS-SCRI will enable GDI engined
vehicles to achieve 50 mpg (highway) while meeting emissions standards to permit
sale in the U.S. as a viable,  near-term  alternative to  longer-term  solutions
such as  improvements  in hybrid  propulsion  systems  or years of  further  R&D
required for fuel cell technology to become practical.

Additionally, independent third-party testing has confirmed the potential of the
SCS application for DI diesel engines to reduce harmful soot in-cylinder without
increasing   fuel   consumption.   Sonex  is  pursuing   joint   marketing   and
commercialization  programs  for the  SCS low  soot  technology  with  committed
industrial partners.

Other SCS designs are being used to convert gasoline engines of various sizes to
operate on safer,  diesel-type  "heavy fuels" for use in military and commercial
applications  requiring  light  weight and safe  handling  and  storage of fuel.
Examples include UAVs (unmanned aerial vehicles) and ATVs (all-terrain vehicles)
such as those used by U.S.  defense forces in  Afghanistan,  as well as outboard
engines, small watercraft used as targets, and generator sets.
