AIS Distribution Agreement

SOFTWARE RADIO TECHNOLOGY PLC                         

                  AIS Distribution Agreement & Order Received                  

The Directors of Software Radio Technology plc ("SRT" or the "Company"), the
AIM-quoted developer of digital wireless communications technology, are pleased
to announce that it has signed an AIS OEM Distribution Agreement with Marine
Electronics Systems Limited ("MES").

MES, which has already placed an initial order under the agreement, is a
rapidly growing UK based distributor of marine electronics with a strong and
growing sales network in the UK and Europe. Under the agreement SRT will
provide MES with OEM AIS products for distribution and sale under the MES and
Digital Yacht brands.

Nick Heyes, Managing Director of MES said: "We are very excited to have secured
an OEM Distributor Agreement with SRT. The product they offer is of the highest
quality and performance and therefore fits well with our brand and product
portfolio. We have seen increasing demand across our sales networks and believe
the AIS market offers us an opportunity to develop a new and significant
revenue stream."

Neil Peniket, Managing Director of SRT Marine Technology Limited said: "MES is
an established, fast growing marine electronics company and we are delighted to
be working with them to maximise the AIS opportunity. There are over four
million commercial and leisure vessels in Europe with approximately 700,000 of
these in the UK. Therefore as awareness of AIS amongst mariners grows and high
quality, low cost AIS products become more readily available, demand for AIS
products is expected to grow strongly."

AIS systems facilitate accurate identification and location of maritime traffic
providing considerable safety and security benefits to mariners and homeland
security agencies such as the coastguard/life boat services.

The AIS market is developing rapidly and SRT continues to build its
international network of partners, working as a long term technology provider
and offering a range of solutions to suit the requirements of the partners.
During 2007 SRT announced an agreement to supply the RNLI and the first
national mandate for AIS was announced by Turkey requiring up to 35,000 vessels
to be fitted with AIS. Further national mandates are expected to follow.
