                Plexus Holdings PLC ('Plexus' or 'the Company')

                   New Contract with Talisman Energy Norge AS


Plexus Holdings PLC, the AIM quoted oil and gas engineering services business,
has signed a contract with Talisman Energy Norge AS ('Talisman'), subject to
completion of relevant contract terms, to supply the Company's proprietary
POS-GRIPTM wellhead systems for use in the Norwegian North Sea.


Talisman will utilise Plexus' exploration rental wellhead equipment, mudline
suspension equipment and service support. Whilst the pressure rating of the
wells being explored are rated at 10,000 psi, Plexus is supplying its standard
15,000 psi High Pressure/High Temperature ('HP/HT') equipment as it is
compatible with the modern drilling rig being used, which has an 18.75 inch
Single Stack 15,000 psi blow out preventer ('BOP'). The Directors believe that
Plexus' equipment offers both flexibility for the latest generation drilling rig
and the best technical solution to be able to run in conjunction with the BOP.


This agreement demonstrates the Company's strengthening relationship with
Talisman and the Directors anticipate that further equipment will be supplied to
Talisman in the future. The oil exploration drilling programme is expected to
commence in late 2007 and continue into 2008, generating initial revenues in
financial year 2007/2008 of approximately £350k. The Directors believe that the
value of the contract could rise to £1.5m.


Plexus CEO Ben van Bilderbeek said, 'This contract is an extension of previous
business activities with Talisman and is the first HP/HT 18.75 inch system that
will be supplied by Plexus to them. It is particularly important to note that we
can demonstrate time cost savings using our proprietary POS-GRIP equipment by
not having to remove the BOP to run the casing. We believe this was a key factor
in our wellhead system being selected for this drilling programme.'
