of 8,519 Ordinary shares of 25p each in the Company at nil cost per share by
Ogier Trustee (Jersey) Limited (the Trustee) as trustee of The BOC Group plc
Employee Share Trust (1995) (the Trust). These Ordinary shares have been

Following this disposal of 8,519 Ordinary shares, the Trustee now holds

executive Director will only be entitled to receive Ordinary shares from the
Trust in satisfaction of options granted to him in respect of these Ordinary
shares.

                 BOC to expand production capacity in Wisconsin
  Gases to serve hospitals, food processors, metals and chemicals manufacturers

Windlesham 9 May 2006 - BOC, one of the world's largest industrial gases
companies, will build a new air separation unit in south central Wisconsin to
strengthen service to Midwestern customers.

BOC is investing for growth where the market conditions are right. This is the
second new air separation plant BOC will begin building this year in the US,
coming hard on the heels of an announcement last month to build a plant in
Georgia. Since 2004, BOC has announced plans to invest more than $250 million in
the US, including three new hydrogen plants.

The plant's exact location is subject to successful negotiations with the state
of Wisconsin and other local approval agencies. The plant will produce over 700
tons a day of liquid oxygen and nitrogen. The gases will be trucked to
hospitals, food processors, metals and chemicals manufacturers in Wisconsin,
Illinois and Iowa.

Construction is expected to begin during the summer of 2006, with production
starting at the end of 2007.

"BOC has seen demand in the Midwest increase steadily over the last few years,
driven mostly by food processing, combustion and petrochemical applications.
We've seen excellent growth in Wisconsin and the greater Chicago area and we are
making this investment in order to improve service to our customers," said
Trevor Burt, president of PGS North America, the BOC business making this
investment.

"One location BOC is considering is in the greater Beloit area, which is located
near many of our major customers in Wisconsin and the Chicago area, has the
zoning and power infrastructure we need and gives us access to many of the
region's major highways," Burt said.



                                                                    Page 7 of 25


BOC will employ between 35 to 40 people at the plant, most of whom will be truck
drivers.

The Wisconsin plant, BOC's first in the state, is the second part of an effort
to streamline the company's Midwest operations. It replaces an older Illinois
plant that was shut several years ago. This new plant is significantly more
energy efficient and has 40 percent greater capacity.

Besides increasing production capacity, the new location enables BOC to optimize
its distribution patterns. Drivers will have to cover less distance to serve
customers in Wisconsin and Chicago and BOC's existing plants in Illinois,
Indiana and Ohio will be able to free up production to support customers located
closer to them.

"This plant will strengthen our supply capability throughout the entire Midwest
and will enable BOC to help customers meet their businesses' changing and
growing demands," Burt said.

The BOC Group is one of the largest and most global of the world's leading gases
companies. Serving two million customers in more than 50 countries, BOC employs
30,000 people and had total annual revenues of (pound)4.6 billion in 2005.

                         refuelling station in Shanghai


Windlesham 11 May 2006 -- The BOC Group plc and Tongji University have signed a
Letter of Intent to build the first hydrogen refuelling station in Shanghai.

project. BOC will provide engineering and procurement services needed to deliver
the packaged hydrogen compression, storage, dispensing system and trucked in
compressed gas hydrogen for the new station. Shell, which is funding part of the
project, is working with Tongji University on the design, construction,
maintenance and operations of the refuelling station.

BOC has previously participated in trials with hydrogen-fuelled buses in London,
Detroit, Vancouver and Perth, Australia.
