OpSec Security to Purchase Light Impressions International Limited

The Acquisition gives our European operations a significant
presence in Asian markets and will be immediately earnings enhancing.

OpSec Security Limited ("OpSec"), a division of OpSec Security
Group plc (London AIM: OSG) today announced the signing of a
definitive agreement to acquire Light Impressions International
Limited, a Surrey, UK based provider of authentication devices. The
purchase price consists of an upfront cash payment of GBP 2.0 million
and a two year cash earn-out capped at GBP 4.5 million, in addition to
which OpSec will pay in cash on a pound for pound basis for the amount
by which Light Impressions´ cash balances at completion exceed its
immediate requirements. The two-year earn-out is to be calculated by
reference to the turnover and gross margin achieved on key customer
accounts during that period. The purchase price will be paid out of
existing cash balances and bank facilities.

Key employees from Light Impressions have agreed to stay with the
business post the acquisition to help ensure a smooth transition and
the early realisation of significant integration benefits.
