              DATAWATCH ACQUIRES MERGENCE TECHNOLOGIES CORPORATION

      NEW ACQUISITION EXTENDS DATAWATCH SOLUTIONS FOR COMPLIANCE, AUDITING,
               ACCOUNTING AND BILLING BUSINESS PROCESS MANAGEMENT

LOWELL, MA - AUGUST 11, 2004 - Datawatch Corporation (NASDAQ: DWCH), a leading
provider of report management, data transformation and service management
solutions, announced that it today acquired Mergence Technologies Corporation,
www.imergence.com, a privately-held provider of content management software
headquartered in Rutherford, NJ. Mergence products enable collaborative,
documented research of enterprise content and metadata to support compliance,
auditing, accounting and billing processes.

             Mergence has been providing enterprise content and research
management services for over five years, primarily to the financial services
sector, with sales in 2003 of approximately $1 million and 2004 year-to-date
sales of approximately $600,000. Datawatch acquired 100% of the shares of
Mergence for $2.5 million in cash. In connection with the acquisition there is a
payout clause, which provides for Datawatch to make cash payments equal to 10%
of the sales of the Mergence Researcher product for a period of six years. The
Researcher product is in its final development stages with a planned release
during this quarter.

            Datawatch will rename the acquired subsidiary Datawatch Technologies
Corporation ("DTC") and plans to consolidate the general and administrative
functions into its headquarters in Lowell, but will retain a sales and support
office in Rutherford, NJ to provide services to customers in the metropolitan NY
area. DTC also has a software development and testing facility in the
Philippines.

            DTC's Researcher product increases productivity, reduces accounting
and reporting errors, enhances collaboration in conjunction with document and
business-process management software, and integrates data and related documents
into a library of meaningful and accessible information that can be shared by
collaborative reporting teams. The web-based enterprise application provides an
easy to use research and



investigation environment, improving the management of data-driven business
processes including compliance, auditing, accounting and billing management,
particularly critical for financial services.

            Commenting on the transaction, Datawatch President and CEO Robert
Hagger said: "The acquired technologies and solutions compliment and further
extend Datawatch's offerings in the enterprise report and content management
markets. This acquisition brings three key additions to Datawatch:

               o    An ongoing revenue stream from existing DTC products and
                    services, primarily marketed in the financial services
                    sector,

               o    An important new product called "Researcher" that we expect
                    will be ready for release to current Datawatch customers and
                    new prospects in this quarter, and

               o    An experienced and cost-effective development team in the
                    Philippines.

            We are particularly excited about the prospects for the Researcher
product; software that searches inter-related data, documents, and
communications scattered over multiple and disparate repositories, then merges
and analyzes the results into comprehensive actionable case records. The
combination of Datawatch|ES, a full featured, compliance-ready enterprise report
management and mining solution, and Researcher will allow our customers to unite
enterprise information to support better decision-making and reporting
activities related to compliance initiatives. Businesses in brokerage, banking,
healthcare and our other key verticals will be able to integrate and reconcile
almost every source of enterprise information, merge and analyze data,
investigate and manage exceptions, and meet regulatory obligations.

            I welcome DTC President Rene Tenazas and his team to Datawatch, and
look forward to working together to help our customers capitalize on enterprise
information to optimize internal and external business reporting."

            Datawatch will discuss the DTC acquisition in a conference call to
be held Thursday, August 26, 2004, at 2 p.m. EDT. The conference call will be
