Establishment of New Company for Participation in R & D Projectof Pore-filling Type Methane Hydrate
It is pleased to announce that Japan Methane Hydrate Operating Co., Ltd. (JMH) was establishedon October 1, 2014 aiming to participate in the Medium to Long-term Offshore Production Test frompore-filling type methane hydrate which will be conducted by the Japanese government.

A substantial quantity of methane hydrate is estimated in the offshore areas around Japan. Serving
as a new domestic energy source, with the potential to make a major contribution to a stable nationalenergy supply for Japan, technological development is expected for its commercialization including
establishment of production technologies. At the end of the fiscal year 2012, Japan Oil, Gas andMetals National Corporation (JOGMEC) carried out the first offshore production test and succeededin the world’s first production of gas from methane hydrate under the seabed. At the end of 2013, theJapanese government announced the latest version of the “Plan for the Development of Marine
Energy and Mineral Resources”, in which the Medium to Long-term Offshore Production Test isplanned.

JMH has been formed with agreement and capital participation of 11 companies engaging in oil andnatural gas development and in plant engineering. The company aims to provide contract services
efficiently, effectively and smoothly on field operations in the offshore production test of pore-fillingtype methane hydrate in “all-Japan” structure, and to share its findings among private-sector in Japan.
Optimizing this structure, participating companies will proactively offer their technologies andknowledge to the Japan’s research and development of pore-filling type methane hydrate toward its
commercialization.
