The Beijing Oil Show extends over 90,000 sq. metres and attracts 1,800 exhibitors from 65 countries and regions, 16 international pavilions and 65,000 professional visitors.

Plexus' CEO Ben Van Bilderbeek said, "I am delighted that Plexus and Jereh have entered into the Agreement which we hope will enable us to bring Plexus' POS-GRIP technology to the important and growing Chinese market and other relevant Asian territories. We view China and Asia as one of the key global market opportunities for Plexus, and we believe that our POS-GRIP wellhead equipment will deliver operational time savings and safety benefits to the oil & gas companies operating in the region, many of whom will be facing high pressure/high temperature ('HP/HT') conditions which POS-GRIP technology is uniquely suitable for, and which has resulted in Plexus supplying wellhead equipment for the majority of HP/HT jack-up wells in the North Sea region.

"The progress we have made to date in our discussions with Jereh is an example of how Plexus continues to extend its geographic reach and we are continuing to see new enquiries from across the globe from operators that are considering POS-GRIP technology. Such progress, and the growing support of our existing and new customers is centred around the principal that we can ensure long-term safety over the lifetime of a production well and beyond. We offer the only wellhead design that can provide a convenient releasable engagement of the casing hanger to the wellhead bore, instantly providing a metal interface seal, which is based on the same principles and performance as those employed in premium couplings design. This remotely delivered and calibrated force eradicates destructive seal movement, and protects seal integrity.

"Plexus has already supplied Shell China with HP/HT POS-GRIP wellhead equipment for an exploration well offshore Hainan Island and we hope to increase our activity in this region. I would like to extend my appreciation to Chairman Sun for the way Jereh and his team have conducted these discussions, and I look forward to finalising the definitive agreements, and working with Jereh over the coming years."

 Kunxiao Wang, President and Co-founder of Jereh said, "We are pleased to announce this alliance with Plexus, which can be a milestone for Jereh entering into the subsea market. Plexus provides unique wellhead system technologies with a strong commitment to make the oil and gas industry much safer and efficient. We are glad to be able to work with such an outstanding partner. By integrating Plexus patented technology and Jereh manufacturing and marketing capabilities, we believe the alliance will create significant influence in the offshore and subsea field and create compelling benefits for customers around the world."

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, 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.
