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

?700,000 New Contract Win with Glencore for Supply of POS-GRIP? HP/HT Wellhead Equipment

Plexus Holdings PLC, the AIM quoted oil and gas engineering services business and owner of the proprietary POS-GRIP? friction-grip method of wellhead engineering, announces that it has agreed to supply its high pressure/high temperature ('HP/HT') POS-GRIP wellhead equipment, subject to finalisation of the contract, to Glencore Exploration Cameroon Ltd ('Glencore'), the leading integrated commodities producer and marketer, for drilling a gas exploration well offshore Cameroon.  The contract will have an estimated initial value of circa ?700,000.

The order is initially for one well with an option to increase this to three. This is the first contract Plexus will enter into with Glencore, and it is anticipated that revenues will commence in March 2013. The exploration drilling programme will utilise Plexus' POS-GRIP HP/HT 18-3/4" 15,000 psi wellhead equipment, and this contract further strengthens the Company's growing presence in West Africa, and Cameroon in particular.

Plexus CEO Ben Van Bilderbeek said, "This first contract to supply our POS-GRIP wellhead equipment to Glencore adds another blue chip operator to our broad customer base, and provides further evidence of Plexus' high standing in the oil and gas industry as a supplier of best in class equipment in terms of operational performance and safety.  In the last few months, we have announced contract wins in three continents, Asia, Europe, and Africa, illustrating how our patented technology continues to gain traction worldwide.  I look forward to providing further updates on our progress as we look to continue to grow Plexus' share in the multi-billion exploration and production market, both surface and subsea, and in the process generate added value for all our shareholders."

Notes to Editors:

Plexus Holdings PLC, which began trading on AIM in December 2005, is an oil and gas engineering and services business, which supplies wellhead and mudline suspension equipment for exploration and production applications.  Based in Aberdeen, with offices in London, Cairo, Kuala Lumpur and a presence in Houston, Texas, it has developed and patented a friction-grip method of engineering for oil and gas field wellheads and connectors, POS-GRIP?, which involves deforming one tubular member against another to effect gripping and sealing.

The Company plans to accelerate the roll out of POS-GRIP wellhead equipment as a superior alternative to current technology and for it to become the future industry standard for wellhead design.  In particular, the technology has advantages in High Pressure/High Temperature (HP/HT) and Extreme HP/HT (X-HP/HT) oil and gas environments, for which there is growing global demand and where Plexus is being increasingly recognised as the supplier of choice.  Importantly, the Company is focussed on extending its proprietary technology into an increasing number of subsea applications.  In line with this, in March 2011 the Company launched an initiative to develop a new subsea wellhead design, HGSST, utilising its friction-grip technology in collaboration with key oil and gas operators and service companies. Royal Dutch Shell, Wintershall, Maersk, Tullow Oil, ENI, Oil States Industries Inc., TOTAL and the UK entity of the world's largest offshore drilling company have joined the initiative to date. The HGSS subsea wellhead design will include a combination of key features never before seen in a subsea wellhead which include being rated to 15,000 psi, 4,000,000 pounds of 'instant' casing lockdown capacity, annulus pressure monitoring and access for 'bleed off' capability to address sustained casing pressure ('SCP') issues which are recognised by the API as a serious industry problem, and rigid metal annular seal technology qualified to match the performance of premium casing.  Development is expected to be completed by mid 2013 calendar year.

To date, POS-GRIP wellhead systems have been used or selected to be used in over 250 oil and gas wells by international companies including Apache Energy Australia, BHP Billiton, BG International, Bowleven plc, BP, Brunei Shell Petroleum, Cairn Energy, Centrica, ConocoPhillips, Dana Petroleum, Dubai Petroleum, GDF SUEZ, Global Santa Fe, Maersk, Niko Resources, Petro-Canada Trinidad & Tobago, Red Sea Petroleum Operating Company, Repsol, RWE, Senergy Limited, Shell Egypt, StatoilHydro, Silverstone Energy, Talisman Energy, Tullow Oil, and Wintershall.
