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

Third Well Order with Maersk Oil for £1.25M

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, is pleased to announce it has secured an additional purchase order with Maersk Oil's Danish business unit to supply its wellhead system and mudline services for a well offshore in the Danish sector of the North Sea. The value of the order is estimated at approximately £1.25 million with revenues commencing in May 2015.

Under the terms of the contract, Plexus will supply its 18-3/4" POS-GRIP surface wellhead and mudline systems for use on the well. This latest order is the third under a contract signed with Maersk Oil and announced on 12 February 2014.

Plexus' CEO Ben Van Bilderbeek said, "We are delighted to have secured an additional order from Maersk Oil's Danish business unit, our third in a little over a year. In our view, winning repeat business from existing customers reflects the operational and safety benefits our proprietary POS-GRIP based wellhead equipment offers. In addition our technology delivers time and cost savings, a major consideration for operators during the current period of heightened oil price volatility. Plexus' equipment therefore allows operators to accommodate the twin pressures facing the industry today, namely increased regulatory oversight and tighter management of costs.

"This is an attractive combination, one which we believe puts us in a strong position to build on the success we have had to date, whereby our equipment has been used in over 350 wells worldwide, and already has a dominant share of the HP/HT North Sea market."

Notes

Plexus Holdings PLC

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 together with associated equipment and services for exploration and production applications. Based in Aberdeen, with offices in London, Cairo, Kuala Lumpur, Singapore 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.

To date, POS-GRIP wellhead systems have been used or selected to be used in over 350 oil and gas wells by international companies including ADTI, AGR, 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, Premier Oil Norge, Red Sea Petroleum Operating Company, Repsol, RWE, Senergy Limited, Shell China, Shell Egypt, Statoil, Silverstone Energy, Talisman Energy, Tullow Oil, and Wintershall.

Importantly, the Company is focussed on extending its proprietary POS-GRIP technology into an increasing number of subsea applications. In line with this, in March 2011 the Company launched a Joint Industry Project ('JIP') initiative to develop a new subsea wellhead design, HGSS™, utilising its friction-grip technology in collaboration with key oil and gas operators and service companies. BG, Royal Dutch Shell, Wintershall, Maersk, TOTAL, Tullow Oil, ENI, Senergy, ADTI and Oil States Industries Inc. The JIP is nearing completion with final qualification testing of all key features of the product under way, and the resultant 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, and importantly rigid metal annular seal technology qualified to match the performance of premium connectors. The building of a single string HGSS prototype wellhead system commenced in February, and is expected to be completed in readiness for display at the SPE Offshore Europe Exhibition and Conference in Aberdeen ('OE2015') in September.

Plexus is an innovative technology company always looking for opportunities to apply its proprietary POS-GRIP friction grip method of engineering to new products both within and outside the oil and gas industry. For example Plexus have recently completed a JIP in conjunction with Maersk to develop a downhole HPHT Tieback connector which for the first time allows the reconnection of production casing to HPHT exploration and production wells. In addition the Company has developed and qualified a new product called "POS-SET Connector™ which is designed to re-establish a connection onto rough conductor casing previously cut above the seabed to facilitate tieback or abandonment operations. The market for permanent plugging and abandonment of wells is increasing in the North Sea and beyond, and could be an important new revenue stream for the company.
