                      NEW JOINT DEVELOPMENT AGREEMENTS FOR
                         PRINTED CIRCUIT BOARD MARKETS

Xaar plc ('Xaar'), the inkjet printing technology group headquartered in
Cambridge, announces two new joint development agreements for applying Xaar's
inkjet printing technologies to the production of printed circuit boards ('PCB')
for the electronics industry.

Xaar and Rohm and Haas announce joint development of digital inkjet printing
systems for the PCB market

Xaar and Rohm and Haas Electronic Materials LLC ('RHEM'), based in Marlborough,
Massachusetts, USA have signed a Joint Development Agreement to produce digital
inkjet printing systems for the application of etch masks and other key
materials and processes used in the fabrication of printed circuit boards.

Both companies are world leaders in their respective fields and share a common
belief that digital inkjet is set to play an increasing role in the future of
the PCB industry.

Xaar and Xennia announce Joint Development Agreement

Xaar and Xennia Technology Ltd. ('Xennia'), based in Royston, UK have signed an
agreement to jointly develop and market matched combinations of printheads and
inks. In particular, the two companies will be focussing on applications for
Xaar's new OmniDot range of printheads in combination with Xennia's innovative
and unique range of metal inks which will allow inkjet printing of conductive
tracks on a wide range of substrate materials as well as offering decorative
opportunities.

Recent developments by Xennia have resulted in a range of metal inks which can
be used in both functional and decorative applications and will allow production
of their own range of specialised printer products incorporating Xaar's
technology. These new inks, particularly when matched with Xaar's 3 pico litre
Omnidot printhead, have the potential to open up a significant range of new
markets for inkjet technology.

Nigel Berry, Deputy Chief Executive and Finance Director, said:

'The printed circuit board market is one which Xaar has identified as offering
excellent potential for its digital inkjet printing technologies, particularly
for prototyping and short-run applications.

'The agreements signed with Rohm & Haas Electronic Materials and Xennia mark an
important step forward for Xaar, covering potential applications in both the
preparation of PCBs for manufacture and the direct printing of conductive
circuits. They reflect the need for close cooperation between development of the
functional fluids, printhead and printing system in order to meet the
requirements of the market.

'These joint development programmes are aimed at addressing the fundamental
problems of applying inkjet printing to this new field and are not expected to
produce significant revenues for Xaar in the immediate future. However, they
represent an appropriate starting point on the road to general exploitation of
inkjet printing in the field of electronics.'
