      DATAWATCH CORPORATION REPORTS RESULTS FOR SECOND QUARTER FISCAL 2005

          REVENUE DECLINES 2% FOR SECOND QUARTER, BUT GROWS 6% FOR THE
                 SIX MONTHS; EARNINGS RETURN TO MODEST PROFIT.


LOWELL, MA - APRIL 25, 2005 -- Datawatch Corporation (NASDAQ: DWCH), a leading
provider of business intelligence, data transformation and IT support solutions,
today announced results for its second fiscal quarter of 2005.


     Revenues for the quarter ended March 31, 2005 were $5,109,000, compared to
$5,195,000 for the quarter ended March 31, 2004. Net income for the second
quarter fiscal 2005 was $6,700 or $0.00 per diluted share, compared to net
income of $396,000, or $0.07 per diluted share, for the second quarter fiscal
2004.


     Revenues for the six months ended March 31, 2005 were $10,196,000, up by 6%
when compared to $9,602,000 for the six months ended March 31, 2004. Net loss
for the six months ended March 31, 2005 was $(147,000) or $(0.03) per diluted
share, compared to net income of $719,000, or $0.13 per diluted share, a year
ago.

     Commenting on the second quarter's results, president and CEO Robert Hagger
said, "Revenue was slightly lower in the second quarter compared to the same
quarter last year, mainly due to a single large order, of which approximately
$348,000 was recognized in the corresponding period last year. We believe that
the year-to-date revenue growth of 6% is a better indicator of the business
trend. While there was no net increase in the number of subscription customers
in the quarter, year-to-date subscription revenue grew to $177,000 compared to
$7,000 for the first six months of fiscal year 2004. This growth in subscription
revenue improves the stability of our future revenue stream."

     "As we noted in the last quarter, we have increased our investment this
year, in sales and marketing, to drive top line growth. Despite this increased
expense level we were able to return the Company to a modest profit and generate
positive cash flow. At March 31, 2005 our cash and marketable securities balance
was $3.5 million, an increase of $99,000 from the first quarter ended December
31, 2004. The Balance Sheet remains strong with no debt."

     "Our investments in research and development continue to extend the
functionality of our existing solutions and create new products. In late March
we released a new version of Monarch. Monarch V8 now provides PC users with the
ability to quickly and easily extract, analyse and export data from PDF files,
HTML files, reports, databases and spreadsheets. Monarch is the industry-leading
analytics tool that allows PC users to export data from any existing
computer-generated report and other data sources without



programming. The increased functionality of working with PDF files now broadens
the potential customer base for Monarch."
