  ACQUISITION OF SYNCHRONICA SOFTWARE GMBH AND BUYOUT OF THIRD PARTY RIGHTS TO
                         SYNCHRONICA SOFTWARE PRODUCTS

DAT Group plc ('DAT' or 'the Company'), a developer and licenser of mobile
device management software, announces the acquisition of the entire issued share
capital of Synchronica Software GmbH ('Synchronica'), a Berlin based software
company which has developed and, subject to the agreement with Ergon Informatik
AG ('Ergon') referred to below, owns data synchronisation and device management
software products. These products are complementary to the DAT Mobility Platform
('DMP') and are based on an industry standard called SyncML. Synchronica's
products are already available on the market and work with OMA (Open Mobile
Alliance) compliant devices.

The technology that the Company has acquired through this acquisition will
accelerate significantly the development and reach of the Tabella offering and
broaden the DMP technology platform. In its simplest version, Tabella (using the
recently acquired SyncML technology) will be aimed at the millions of users of
mid range devices who have no way of backing up their contacts. It will also
help DAT to address an even larger market for active data synchronisation and
device management for large mobile phone operators.

The consideration for the acquisition of Synchronica was €400,000 in cash paid
on completion (31 March 2005), €100,000 in cash payable 12 months after the date
of completion and the allotment to the vendors of options in respect of new
Ordinary shares in DAT with a market value of €250,000. The cash consideration
will be satisfied from the Company's existing cash resources.

Agreement has also been reached for the variation of a contract between
Synchronica and Ergon under which Ergon undertook to maintain and develop
Synchronica's OMA Direct Sync software products in return for a 20% revenue
share. This variation agreement became effective on completion of the
acquisition of Synchronica. Under the variation agreement, Ergon vests with
Synchronica all current and future rights to the OMA Direct Sync products'
source codes worldwide. The variation agreement also eliminates Ergon's historic
20% licence revenue entitlement whilst ensuring that Synchronica continues to
receive a 50% share of all licence fees resulting from sales by Ergon of
SyncML-DS products.

The consideration payable to Ergon under the agreement is €600,000, of which
€400,000 was paid on completion of the acquisition of Synchronica out of the
Company's existing cash reserves. Deferred consideration of €200,000 will be
released in monthly instalments over the following 12 months subject to Ergon
meeting commitments to supply further agreed developer time on the SyncML-DS
products.

Commenting on the transactions, David Hayes, DAT's Chief Executive, said 'There
is clear market demand for our DMP platform to include a SyncML capability.
Synchronica brings DAT a suite of well regarded, live products which
significantly extend DMP's reach and addressable market. The acquisition will
help us to address, immediately, an area of growing importance for many of the
large mobile phone operators - active data synchronisation and device
management.
Additionally, we expect the acquisition to accelerate the development and reach
of our recently announced Tabella e-mail service. There is much work now to be
done to integrate these products into our software solutions.'
