17th September 2007



                              Plexus Holdings PLC

                          ('Plexus' or 'the Company')

          New Contract with Norsk Hydro Produksjon AS ('Norsk Hydro')



Plexus Holdings PLC, the AIM quoted oil and gas engineering services business,
has signed a contract with leading offshore oil company Norsk Hydro Produksjon
AS to supply a proprietary POS-GRIP(R) wellhead system for use in the Norwegian
North Sea. This agreement marks the first working partnership between the
companies, which Plexus hopes to build upon in the future. The immediate value
of the contract is approximately £700,000, with revenues commencing in the last
quarter of the company's financial year to 30 June 2008.

Plexus will supply Norsk Hydro with POS-GRIP High Pressure/High Temperature ('HP
/HT') exploration rental wellhead equipment, mudline suspension equipment and
service support.   The Directors believe that Plexus' equipment offers the best
technical solution for exploration wells drilled from the latest generation of
Jackup rigs, as it allows the blow out preventer ('BOP') to remain in place for
the well, providing time savings and safety benefits.

The POS-GRIP method of engineering for wellheads and connectors has many
advantages in dealing with the high forces associated with the HP/HT oil and gas
environments, for which there is increasing global demand due to the strong
energy appetite and the need to explore for oil and gas in ever more challenging
locations.  With growing support from many of the oil and gas majors for Plexus'
proprietary POS-GRIP technology, the Company is ideally placed to build upon
this with the aim of developing POS-GRIP wellheads as a new industry standard.

Plexus CEO Ben van Bilderbeek said, 'This is a significant contract win for
Plexus as it represents the first working partnership for both companies and is
further corroboration of the particular suitability of our technology for the
more unconventional and technically challenging offshore drilling applications.
POS-GRIP provides a number of key advantages which are particularly beneficial
in relation to a HP/HT rental wellhead contract, including considerable time and
cost savings and enhanced safety.'

Plexus, which began trading on AIM in December 2005, is an established oil and
gas engineering, and services business based in Aberdeen, with an office in
London and a presence in Houston, Texas. It has developed and patented a method

by international companies including BHP Billiton, BP, Brunei Shell Petroleum,
ConocoPhillips, Gaz de France, Global Santa Fe, Maersk, Petro-Canada Trinidad &
Tobago, Repsol, Talisman Energy, Tullow Oil, and Wintershall.

The Company plans to accelerate the roll out of POS-GRIP technology as a
superior alternative to current wellhead technology. It has particular
advantages in HP/HT oil and gas environments for which there is increasing
demand throughout the world. The Company's long-term goal is to develop POS-GRIP
technology as the future industry standard for wellhead design. This objective
includes the distribution of POS-GRIP technology through licensees to maximise
