DATAWATCH CORPORATION REPORTS THIRD QUARTER
                                    EARNINGS

      DATAWATCH ANNOUNCES YEAR-TO-DATE REVENUE GROWTH OF 4% AND NET INCOME
                                  GROWTH OF 23%

LOWELL, MA - JULY 22, 2004 -- Datawatch Corporation (NASDAQ: DWCH), a leading
provider of business intelligence, data transformation and IT support solutions,
today announced results for its third fiscal quarter.

     Revenues for the quarter ended June 30, 2004 were $4,709,000, a decrease of
8% from $5,101,000 in the same period of fiscal 2003. Net income for the third
fiscal 2004 quarter was $100,000, or $0.02 per diluted share, compared to
$698,000, or $0.13 per diluted share, a year ago. Our fiscal 2003 third quarter
was favorably affected by a catch-up effect from the previous quarter when
revenue was depressed by international affairs. Costs in this year's quarter
reflect our increased investment in marketing and sales activities.

     Revenues for the nine months ended June 30, 2004 were $14,311,000, an
increase of 4% from $13,710,000 in the same period of fiscal 2003. Net income
for the first nine months of fiscal 2004 was $819,000, or $0.14 per diluted
share, compared to $665,000, or $0.12 per diluted share, a year ago.

     Commenting on the third quarter's results, president and CEO Robert Hagger
said, "Revenue was lower in the third quarter compared to the same quarter last
year, but we continued to perform well in terms of new orders booked. In
November 2003, Datawatch added a subscription model as an optional method of
purchasing our products and we are pleased by the customer response. This new
initiative provides customers with an alternative to the outright purchase of
software and can save on the high capital investment that is needed for larger
projects. By using the Datawatch subscription model, companies can simply
expense a monthly fee. The business advantage for Datawatch is that it reduces
quarterly sales volatility and helps create a larger customer base for future
business opportunities. We recognize revenues from such orders over the period
of the contract and account for the sales and marketing expense as incurred.

     We are pleased with our year-to-date improvements with revenues up 4% and
net income up 23% over last year. We continue to generate positive cash flow,
while investing in activities designed to improve the market awareness of our
products and increase the coverage and effectiveness of our sales force.

     Investments in research and development continue to extend the
functionality of our existing solutions and create new products. The recently
announced .NET version of


Monarch DataPump will provide users with the means to easily deploy and
integrate DataPump with other Microsoft solutions. The increased functionality
also broadens the potential customer base for Monarch DataPump, and again
demonstrates our ongoing commitment to helping customers improve the
productivity of information users in the workplace."

     Datawatch previously announced that the company will present and discuss
its third quarter results today at 2 p.m. (EDT) in a live conference call
broadcast via the Internet at http://www.vcall.com/ClientPage.asp?ID=88513.
