Oxford Instruments plc

Acquisition of Technologies and Devices International, Inc.


Oxford Instruments plc ("Oxford Instruments" or "the Group"), the high
technology tools and systems company, today announces the acquisition of
Technologies and Devices International, Inc. ("TDI" or "the Company"), a US
based company which is a world leader in the development of Hydride Vapour Phase
Epitaxy (HVPE) technology and processes. Using this technology, Oxford
Instruments intends to produce tools that enable suppliers of High Brightness
Light Emitting Diodes (HBLEDs) to cut manufacturing times by 25%, allowing a
reduction in the production costs of these environmentally friendly devices.

Domestic and commercial lighting made from HBLEDs is currently about 10 times
more efficient than tungsten bulbs and twice as efficient as Compact Fluorescent
Lighting. Analysts predict that the market for HBLEDs will grow at a CAGR of 20%
to 2012.

Oxford Instruments currently sells process tools to complete three of the nine
steps needed to manufacture HBLEDs. This acquisition allows the Group to supply
tools for a fourth step that has historically been the most time consuming and
costly with a unique offering that will greatly enhance production efficiencies.

The consideration consists of an initial payment of US $1.0m cash, plus a cash
earn-out, payable in July 2012 based on the sales of tools in the preceding
financial year. The total consideration is capped at US $6.0m. TDI is currently
owned by private individuals, predominately comprising members of the founder's
family and employees. Oxford Instruments will assume the Company's debts at
acquisition of US $2.2m.

For the year ended 30 June 2007, TDI made a loss before tax of US $0.8m. At 30
June 2007 gross assets were US $1.0m. It is estimated that losses will continue
for the first year of the Group's ownership while process tools are developed
but that the acquisition will be earnings enhancing in the second year.

Jonathan Flint, Chief Executive of Oxford Instruments plc, commented: "The
acquisition of TDI is entirely consistent with the strategy put in place by the
Oxford Instruments Board to acquire complementary technologies to support our
objective to double the size of the Group over five years and improve EBIT
margins by 10 percentage points. TDI is an excellent business with proprietary
technologies in a market that is set to grow very significantly. We will be
among the market leaders in this valuable and vital segment."
