capital of $527,085 last year, liabilities have been reduced from $2,074,807

equity improved markedly with a consolidated equity of $586,847 at
February 29, 2004, up from an equity deficiency of $639,453 at February 28,

have noted a resurgence in new business prospects during the last two
quarters, particularly in the electronics markets with new orders for the
Company's latest solder flux application system, the SonoFlux 2000F.  We have
sold many systems specifically designed for applying anti-restenosis drug
coatings to arterial stents.  Customers in the nanotechnology field continue
to use our ultrasonic nozzle systems to apply nanophase liquids to their
products and we are optimistic about additional opportunities in this growing
business area.  We are continuing to develop coating systems for medical
device customers and other customers in a diverse range of industries from
food processing to plate glass manufacturing."
