FOR IMMEDIATE PRESS RELEASE



                  MITSUI JOINS IN ALTAMIRA LNG TERMINAL PROJECT

Shell Gas B.V. (Shell) and Mitsui & Co., Ltd (Mitsui) are pleased to announce
that Mitsui will acquire a 25% equity participation in the LNG terminal in
Altamira, Mexico, which is currently owned by Shell (75%) and Total (25%). The
transaction is subject only to approval of the Mexican authorities. Upon
completion of the transaction, the equity interests in the LNG terminal will be
Shell 50%, Mitsui 25% and Total 25%.


All of the terminal regasification capacity continues to be contracted to a
separate marketing company owned by Shell (75%) and Total (25%). The total
project cost is estimated roughly US$ 400mm for the terminal construction. Last
year Comision Federal de Electricidad (CFE) awarded this marketing company a
contract to supply 5 billion cubic metres of regasified LNG per annum
(equivalent to 3.6 million tonnes of LNG per year (mtpa)) for 15 years starting
in October 2006.

The Shell led project will be the first new LNG regasification terminal built in
North America for over 20 years and is expected to start operations in the
fourth quarter of 2006. Depending on the growth in demand for natural gas in
North East Mexico, the terminal could be expanded to 10 mtpa.

The divestment of 25% of Shell's interest in this terminal reinforces Shell's
strategy to focus on LNG supply, capacity rights and access to markets. It
follows closely on the recent signing of a 20-year agreement by Shell to take
half of the initial capacity at the LNG regasification terminal in Baja
California, Mexico. At the same time, the purchase of the 25% stake in the
Altamira terminal is in line with Mitsui's strategy of increased investment in
strategic energy supply chain infrastructure, building on its successful tender
earlier this year for development of an independent power project in Mexico.

Catherine Tanna, Shell Gas & Power Director, Americas and Africa, said: "Shell
is delighted that Mitsui has joined us in the Altamira project. This deal
confirms the confidence of a major foreign investor in the fundamentals of the
Mexican energy market. The agreement shows further delivery of our strategy to
retain capacity rights in LNG projects around the world."

Michio Matsuda, Mitsui & Co., Ltd., Executive Managing Officer, said: "Mitsui
shares Shell's view of the potential of Mexico's natural gas market and its need
for more natural gas infrastructure. Mitsui is pleased to expand our portfolio
in the area of energy related infrastructure investment as well as our
relationship with Shell through this first participation in an LNG terminal."

                                       1

Notes:

The terminal will consist of two LNG storage tanks of 150,000 m(3) and will be
able to accommodate ships of up to 200,000 m(3) in size. The initial send-out
capacity of the terminal will be 0.5 billion cubic feet per day (Bcf/d)
(equivalent to 3.6 mtpa). Construction began in 2003.

Shell is currently the largest supplier of equity LNG globally. Its current
projects globally include Nigeria LNG, Oman LNG, North West Shelf (Australia),
Malaysia LNG, Brunei LNG and Sakhalin.

Mitsui is focusing to expand the energy related infrastructure investment
worldwide, such as independent power projects (IPPs), gas pipelines and
terminals.
