Radstone Technology PLC
11 November 2005


Immediate Release                                              11 November 2005

                      Radstone Technology PLC ("Radstone")

                         $12 Million Contract Extension

     "Further demonstration of Radstone's leadership in rugged, commercial
                   off-the-shelf (COTS) computing technology"

Following clearance from its customer, Radstone Technology PLC (LSE:RST), the
world's leading independent supplier of high-performance, embedded computer
products for defence and aerospace applications is pleased to announce that in
September 2005 it received an extension to the existing ATFLIR contract from the
Raytheon Company.

The contract extension is scheduled for delivery over the next five years, and
has a net additional value to Radstone of approximately $12 million.

The ATFLIR (Advanced Targeting Forward-Looking Infra Red) systems contract was
originally granted from Raytheon in June 1998 and requires Radstone to supply
their PPC4A single board computer, MIL STD 1553 interfaces and Fibre Channel
modules for incorporation into Raytheon's 521 ATFLIR pods.

With its enhanced target detection and recognition range, ATFLIR substantially
extends the capability and survivability of the US Navy's F/A-18 Hornet fighter
aircraft squadrons worldwide. Among its benefits is delivery of a substantial
increase in target detection/recognition range over first-generation systems,
and pinpoint accuracy and assessment from longer standoff ranges. Its target
detection range shows a four-fold improvement over previous systems, and laser
designation is effective at altitudes up to 50,000 feet and at a slant range of
greater than 30 miles. These features enhance F/A-18 aircrew survivability,
allowing the pilot and weapon systems operator to strike from safer distances.

Jeff Perrin, Chief Executive of Radstone Technology PLC, commented :

"This latest order is a further demonstration of Radstone's leadership in
rugged, commercial off-the-shelf (COTS) computing technology - and also of the
excellent long term working relationship we have with Raytheon.

ATFLIR's multifunctionality, its versatility and its interoperability are
characteristic of the latest generation of systems designed for network-centric
warfare, the goal of which is to deliver battlefield advantage through superior
information acquisition and communication. Our product range is specifically
designed with these needs in mind."
