Cohort plc (www.cohortplc.com)

Cohort plc is a defence technical services group. It operates through two wholly-owned subsidiaries, MASS

service providers, working for defence, wider government and industry clients.

- MASS (www.mass.co.uk) was acquired by Cohort plc in August 2006 for an initial consideration of Pounds Sterling
12.5m and is an independent UK Systems House focused on the defence and aerospace markets. MASS offers specialist
skills in four main business areas: Managed Services, Electronic Warfare, Secure Communications and Information
Systems.

- SCS (www.scs-ltd.co.uk), Cohort plc's original operating company, provides independent consultancy support,
which combines technical expertise with practical experience and domain knowledge, primarily but not exclusively
to the defence sector.

defence technical services market and was admitted to trading on AIM on 8 March 2006.
