                       SRT signs strategic AIS agreement                       

Software Radio Technology plc ("SRT" or the "Company") is pleased to announce
that it has signed a strategic agreement with an existing customer to develop
and deliver a new generation of AIS products during 2011.

The customer is one of the world's top three marine electronics companies and
SRT will use its new range of AIS technologies to deliver a series of new low
cost AIS products for this customer. The products will replace the existing
products being supplied to the same customer by SRT and are expected to start
shipping from September 2011.

As part of the agreement SRT and the customer have made a commitment to work
more closely together to exploit AIS market opportunities.

Simon Tucker, SRT's Chief Executive Officer, said: "Over the past few years we
have formed a close relationship with this customer who is primarily focused on
the leisure market. This agreement takes our relationship to a new level for
the long term. Using SRT's new range of AIS technologies will ensure that the
customer has a market leading AIS offer within its extensive portfolio of
marine electronics."
