LOWELL, MA - APRIL 22, 2004 -- Datawatch Corporation (NASDAQ: DWCH), a leading

     Commenting on the second quarter's results, president and CEO Robert Hagger

services revenues up from last year for both the quarter and year-to-date. We
have been diligently working through our plan, which was to continue to improve
our profitability and cash position. The quarter and half-year results were
solidly profitable and our cash position increased by $1 million for the six
months and by more than $3 million since March 31, 2003. At the same time we
have invested resources to improve the market awareness of our products and
expand our sales force, with sales and marketing expenses increasing by more
than $400,000 in the second quarter when compared to the previous quarter.

     We are also continuing to invest in research and development to extend the
functionality of our existing solutions and to create new products. Our recently
announced Datawatch|ES TotalView module will provide our users with the means to
easily access and join data from disparate systems into new reports. This
increased functionality broadens the potential customer base for Datawatch|ES
