              SONO-TEK NAMED AVERILL HARRIMAN EXPORTER OF THE YEAR

    MILTON, N.Y., May 5 /PRNewswire-FirstCall/ -- Sono-Tek Corporation (OTC
Bulletin Board: SOTK) the world's leader in ultrasonic spray nozzle technology,
announced today that they had won an Averill Harriman International Trade Award
as Exporter of the Year in the under $10 million category. The award was
presented to Sono-Tek's President and CEO, Dr. Christopher L. Coccio, Ph.D. at
an awards ceremony held May 3rd in Newburgh, New York. Companies from six
counties in the Hudson Valley were eligible.

    Dr. Coccio stated "Sono-Tek has been selling products internationally for
almost 30 years. Beginning in 1993, we focused our marketing on the Mexican
electronics market and engaged Mexican sales representatives. We were able to
establish an export business that concentrated on the introduction of our spray
fluxing equipment into wave solder machines being purchased for circuit board
assembly in Mexico. With the NAFTA Agreement, export sales expanded as many of
the Company's US customers in the automobile and consumer electronics markets
moved their assembly operations to Mexico.

    Over the past few years, we began to expand our foreign customer base
outside of Mexico primarily in the Far East and Europe. Our focus has been to
sell not only to the electronics assembly industry, but also for applications in
other industries, where our unique technology brings benefits. These
applications include coating arterial stents; apply thin coating onto wide webs
of plate glass, and several other applications. These new products have
account-ed for an overall increase in sales from $3.5 million last year to
almost $6 million this year, and the export content has increased from 20+
percent to over 40 percent this year."

    Further he stated, "More recently we have expanded our sales and marketing
efforts into former Soviet Bloc eastern European countries and have thus far met
with enthusiastic responses"

    Dr. Coccio noted the assistance provided to Sono-Tek over the past several
years by the Ulster County Development Corporation, NYS Empire State
Development, and the US Department of Commerce in facilitating its technology
and export growth.
