  DATAWATCH CORPORATION REPORTS EARNINGS FOR ITS FOURTH QUARTER AND FISCAL 2004

        DATAWATCH ANNOUNCES YEAR-ON-YEAR REVENUE GROWTH OF 9% AND INCOME
         FROM OPERATIONS GROWTH OF 12%; CASH RESERVES OVER $4.2 MILLION

     LOWELL, MA - NOVEMBER 23, 2004 -- Datawatch Corporation (NASDAQ: DWCH), a
leading provider of business intelligence, data transformation and IT support
solutions, today announced results for its fourth quarter and fiscal year ended
September 30, 2004.

     Revenues for the year ended September 30, 2004 were $19,335,000, an
increase of 9% from $17,712,000 for fiscal 2003. Income from operations for
fiscal 2004 was $925,000, an increase of 12% from $826,000 for fiscal 2003. Net
income for fiscal 2004 was $1,085,000, or $0.19 per diluted share, compared to
$847,000, or $0.16 per diluted share, a year ago.

     Revenues for the quarter ended September 30, 2004 were $5,024,000, an
increase of 26% from $4,002,000 for the same period of fiscal 2003. Net income
for the fourth fiscal 2004 quarter was $266,000, or $0.05 per diluted share,
compared to $182,000, or $0.03 per diluted share, a year ago.

     In the fourth quarter, Datawatch recorded a benefit for income taxes of
$148,000 for the recognition of a reduction in the valuation allowance as a
result of realizing the benefit of certain of the Company's deferred tax assets
resulting from the deferred tax liabilities associated with the Mergence
acquisition. The benefit is included in net income for both the year and quarter
ended September 30, 2004.

     Commenting on the fiscal 2004 results, president and CEO Robert Hagger
said, "I am very pleased with the solid progress we have made this year and with
the fiscal year results. Our accomplishments in fiscal 2004 include:

     o    An increase in sales on all product lines resulting in a 9% overall
          improvement in recognized revenue for the year,

     o    An improvement in income from operations of 12% versus fiscal 2003
          with income from operations increasing from $826,000 to $925,000,

     o    The creation of a larger and stronger sales and marketing resource to
          support future sales performance improvements,


     o    The launch of a new subscriptions sales model providing a new
          recurring revenue stream for fiscal 2005 and beyond,

     o    The acquisition of Mergence Technologies Corporation providing
          Datawatch with an added revenue stream and an exciting new product
          range.

     In addition to the continued earnings trend and solid net cash position in
fiscal 2004, the introduction of a new subscription model for customers of
report management and service management products was well received by our
customers. The new pricing model lowers the initial cost of software acquisition
for our customers, making it easier for them to start using our products. For a
simple monthly fee, users can now have access to large-scale systems that
improve productivity in the workplace by better information and business process
management. This key initiative is designed to grow our enterprise business,
reducing dependency on short-term sales and building a recurring revenue stream
over the next few years.

     Our continued investment in research and development of report management
technologies has resulted in Datawatch becoming a leader in report-based
business intelligence software and systems. From individual desktop applications
through to full enterprise-wide report access and distribution methods,
Datawatch is providing easy to implement solutions that deliver a strong return
on investment for our customers. During 2004, Datawatch has added to the
capabilities of its report management systems by providing the ability to search
inter-related data over multiple and disparate repositories, data, documents,
communications and summarize into auditable case records, stored for corporate
compliance and collaboration. This new initiative now provides Datawatch with
the ability to manage both structured and unstructured data.

     Based on industry analyst Gartner, Inc., IT services projections call for
the market in the areas of business intelligence and data warehousing to grow
from $17.3 billion in 2002 to $26.4 billion by 2007, an 8.9 percent CAGR.
Datawatch is now well placed to take advantage of the expected growth in this
market. Our base of over 20,000 customers, including a significant number of
Fortune 500 companies, is an excellent on-ramp to this opportunity. The next
stage for Datawatch is to continue to grow revenues and achieve greater market
share. We are focused on the task and have increased the size of our sales force
in preparation for fiscal 2005.

     In addition to extending our business intelligence range, we also expanded
our technology capabilities and customer base in the service management space.
Offerings now range from an easy to deploy web-based Visual Help Desktm On-Line
model, through to our full business process management (BPM) suite, Visual|QSM.


     With an improving economic climate, Datawatch is well positioned to take
advantage of the recovery as it unfolds and we eagerly look forward to an
exciting fiscal 2005."
