sales of $690,735 for the same period of last year.  For the six months ended

2004 was $233,680 and $ 396,251 (both 15% of sales) compared to $41,472 and
$102,255 (6% and 7% of sales, respectively) for the same periods of the prior
year.  For the three and six months ended August 31, 2004, the Company had
record net income of $207,114 and $341,724 compared to $5,749 and $16,795 for
the three and six month periods ended August 31, 2003.
    The balance sheet is improved from last year at this time with working
capital at $1,306,166 at August 31, 2004 from working capital of $569,753 last
year and shareholders' equity improved from a deficit of $622,658 at August
31, 2003 to positive equity of $1,074,507 at August 31, 2004.  The Company has
reduced or repaid $240,000 of its subordinated mezzanine debt since February
29, 2004.
    The Company's sales levels have increased as the result of an improved
economy, product development efforts, and related marketing initiatives, which
have had the effects of improving net income, reducing debt, and bringing
shareholders' equity from a deficit position to a positive position.
    According to Dr. Christopher L. Coccio, Sono-Tek's CEO and President, "At
our Annual Meeting of Shareholders in August, we reported that we were
experiencing growth at a rate over 50%.  In fact our year to date performance
exceeded our expectations and we experienced sales growth of 88%.  During this
quarter we also announced the introduction of our MicroMist stent coating
system, a strategic alliance with the nanotechnology firm, NanoBiomagnetics,
and the selection of Sono-Tek as the distributor in the U.S. and Canada for
EVS International's solder recovery system.  We recently showed the EVS
product line at the Assembly Technology Exhibition in Chicago, where it was
received enthusiastically."
    Further he stated, "This quarter's operations point out the diversity of
Sono-Tek's current product line.  We achieved sales growth in all of our
market areas: electronics, industrial coatings and medical coatings.  We are
excited about our strengthening business prospects and look forward to
continued growth in future quarters."
