       DATAWATCH CORPORATION REPORTS RESULTS FOR THIRD QUARTER FISCAL 2005

  REVENUE GROWS 19% IN THIRD QUARTER, AND 10% FOR THE NINE MONTHS YEAR-TO-DATE


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

     Revenues for the quarter ended June 30, 2005 were $5,619,000, up by 19%
when compared to $4,709,000 for the quarter ended June 30, 2004. Net income for
the third quarter fiscal 2005 was $330,000 or $0.06 per diluted share, compared
to net income of $100,000, or $0.02 per diluted share, for the third quarter
fiscal 2004.

     Revenues for the nine months ended June 30, 2005 were $15,815,000, up by
10.5% when compared to $14,311,000 for the nine months ended June 30, 2004. Net
income for the nine months ended June 30, 2005 was $183,000 or $0.03 per diluted
share, compared to net income of $819,000, or $0.14 per diluted share, a year
ago.

     As of June 30, 2005, the Company had $4.4 million in cash and marketable
securities, an increase of $0.8 million or 23% from the second quarter, and no
long-term debt.

     Commenting on the third quarter's results, president and CEO Robert Hagger
said, "We are excited by the progress being made at Datawatch. A good result was
achieved in our third fiscal quarter by significant improvements to revenue and
net income, compared to the same period last year"

     "The increase in sales is attributable mainly to license revenue generated
by the successful launch of Monarch V8. Monarch is used in 95% of the Fortune
1,000 companies as a desktop report-mining tool for legacy data. Now with added
capabilities to easily extract, analyze and export data from PDF files, as well
as HTML files, reports, databases and spreadsheets, the market for this product
has expanded. The new version was launched late in March 2005, prior to our
successful user conference in San Diego, California".

     "Revenue from Enterprise-scale Business Intelligence and Service Management
products was up by only 3% compared to the same quarter last year, partly due to
a shift from our traditional licensing model towards a subscription licensing
model. In spite of this shift, recognized revenue increased by 7% for the fiscal
year-to-date. Nine new subscription orders were taken in the quarter, helping to
add to the growing subscription revenue stream of $129,000 for the quarter as
compared to $3,000 in the same period last year, and $307,000 year-to-date
versus $10,000 last year. We continue to invest in growing the business over the
medium term. Sales and marketing expenses for the first nine months of this
fiscal year was $6.5 million versus $5.5 million a year ago, and research and
development expenses increased $681,000. We are very pleased by this quarter's
results and satisfied with our year-to-date position."
