RESTATED RESULTS FOR THE YEAR TO 30 SEPTEMBER 2005


BOC has today released annual and quarterly results for the financial year to 30
September 2005 restated under International Financial Reporting Standards
(IFRS). These can be viewed in detail on The BOC Group website using the link
below.

http://www.boc.com/investors/annual_and_quarterly_reports/2005/ifrs_restatement
--------------------------------------------------------------------------------
..pdf
----


Under IFRS

o    Basic earnings per share were 75.5p compared with 74.1p under UK GAAP.
     Basic earnings per share before exceptional and certain re-measurement
     items were 67.8p compared with 67.5p under UK GAAP.
o    Net assets at 30 September 2005 were (pound)2,040.4 million compared with
     (pound)2,053.1 million under UK GAAP

It is important to note that IFRS does not affect the underlying economics of
the business and has no strategic implications. The implementation of IFRS may
result in increased volatility in future reported results principally due to
changes in the accounting for financial instruments and foreign exchange.

In terms of presentation, the most significant change relates to BOC's joint
ventures and associates. While these continue to be equity accounted, BOC's
share of JVs and associates are excluded from both Group revenue and Group
operating profit under IFRS. BOC's share of their after-tax earnings is shown in
profit before tax. However BOC will continue to present additional non-statutory
information to facilitate a full segment analysis including JVs and associates
(please see sections 4.5, 5.2 and 5.3 in the release).

THE BOC GROUP plc ANNOUNCEMENT RELEASED TO A REGULATORY INFORMATION SERVICE

27 JANUARY 2006


THE BOC GROUP plc - ANNUAL GENERAL MEETING

STATEMENTS MADE TO SHAREHOLDERS BY MR ROB MARGETTS CBE, CHAIRMAN, AND MR TONY
ISAAC, CHIEF EXECUTIVE

Mr Rob Margetts CBE

Good morning, ladies and gentlemen, and welcome to the 120th Annual General
Meeting of The BOC Group. These are exceptional times and to reflect that fact I
will concentrate on the topic that is no doubt at the forefront of your minds -
the unsolicited, preliminary approach for your company from Linde and your
board's rejection of it.

First I would like to say your company is in excellent health, strategically,
operationally, financially and managerially. Not only did we produce record
earnings in the past financial year but we have embarked on a wide-ranging
investment programme, including the construction of ten significant new plants
this year. We are the largest gases group in Asia and have a leading position in
China, the world's fastest-growing industrial nation. We are winning a high
percentage of all new business in the industrial gases market including in
hydrogen, where our share of new business is almost double its historical market
share

2005 was another good year, with adjusted earnings per share at 67.5p, and your
company has outperformed the FTSE100 by over 64 per cent in the five year period
from October 2000 to the end of September 2005. Tony will explain shortly how we
have achieved that. It has been done with a great deal of hard work and a sense
of vision that drives the entire business.

That brings me to the announcement that we made earlier this week, rejecting the
unsolicited approach from Linde. This was a unanimous rejection by your board.
Your directors were extremely mindful in making this decision of their
responsibilities to you, our shareholders.

Many of you are long-standing shareholders of BOC and will remember the
ten-month period of damaging uncertainty some six years ago after BOC agreed to
a preconditional offer from Air Products and Air Liquide. The preconditional
offer failed when they did not get the consents they wanted. Whether or not the
issues are less in the case of Linde does not hide the fact that regulatory
clearance was a precondition.



                                                                  Page 22 of 38





The unsolicited approach from Linde also contained regulatory hurdles as a
precondition, which meant your company would inevitably have had to suffer a
further period of uncertainty while these were examined.

The proposal was conditional on financing arrangements that had to be finalised
and they were themselves subject to commercial due diligence.

These preconditions were onerous enough but also the proposal failed to take
account of the growth prospects for your company. Our successes in the hydrogen
market and in Asia are examples of the strengths and the potential of the Group
and Tony will expand on this.

BOC is an exciting global company with strong positions in growth markets, a
stated commitment to delivering shareholder value and an excellent management
team. As a board we are confident in the current strategy of the Group to
deliver growth and excellent returns to you, our shareholders, and in the
ability of Tony Isaac, his executive team and all our people.

Mr Tony Isaac

Good morning ladies and gentlemen.

We finished 2005 with record adjusted earnings per share; our adjusted return on
capital employed rose to16.2 per cent; and our balance sheet was strong on the
back of continued good cash generation. We have worked hard over the last six
years to develop your company and before I look to the future let me remind you
of the strategic themes we have consistently pursued.

We knew that the oil and refining industries would be strong growth markets. We
foresaw increased demand for hydrogen to improve the refiners' returns on each
barrel of oil and to meet ever stricter environmental conditions. We saw
increased need for nitrogen for enhanced oil recovery. By focusing on these
growth markets we increased our sales from hydrogen and HyCO schemes by an
average of more than 30 per cent each year from 1999 to 2005 and for 2005 to
2007 we expect them to grow at the rate of nearly 40 per cent a year. We have
won hydrogen business at almost double our historic market share. At the world's
largest nitrogen scheme in Mexico, which is used to enhance oil recovery, we are
currently investing in a fifth module, having increased our share of the joint
venture from 35 per cent to 65 per cent in 2004.


                                                                  Page 23 of 38




We have been successful in selecting and developing our share of growing
industrial markets and we have also succeeded in sustaining our leading position
in Asia, and particularly in China. Asia already generates over 20 per cent of
Group revenues. We have invested steadily in Asia over many years and our
success rate this decade has seen the sales of our businesses in China alone
climb from (pound)50 million in 1999 to (pound)99 million in 2004, and they will
increase to well over (pound)200 million a year when plants currently on order
are installed. Our aggregate interest in these businesses is 50%.

We have a good pipeline of projects. Process Gas Solutions is currently
executing projects around the world that will require investment of some
(pound)485 million. Some of this will be with our joint venture partners and so
BOC's investment will be about (pound)300 million, generating profits of around
(pound)30 million in the first full year of operation.

We have been active in leading profitable local consolidation in the industrial
gases industry through divestments, mergers and acquisitions. Through these
local deals we have captured most of the potential synergies available to us in
markets such as Poland, Japan and Canada. Most recently we have divested our
Afrox hospitals business to a group led by black economic empowerment investors,
keeping a 20 per cent share of the equity of the new business.

Our Industrial and Special Products line of business has number one positions in
many important geographies. ISP's well developed distribution channels, its wide
range of customers, and its high levels of customer service have enabled it to
achieve sustained growth in both our traditional and new markets.

At BOC Edwards, while it continues to strengthen its market position we need to
improve returns and are acting on it.

While encouraging growth we have increased return on capital employed to 16.2
per cent in 2005, reducing borrowings in the process and strengthening our key
financial ratios.

Your Group and the people who work within it have achieved a lot over the past
six years.

Looking to the future, the Group is well positioned for growth. We have made
good progress in the first quarter of 2006 and continue to pursue our
longer-term investment plans. We continue to be confident that the current
strategy of the Group will deliver growth and excellent returns to you our
shareholders.

Dear Shareholder

Statement Relating to Preliminary Proposal

On 24 January 2006 The BOC Group plc ("BOC") issued an announcement confirming
that it had received an unsolicited preliminary proposal from Linde AG
("Linde"). The proposal was subject to a number of pre-conditions including
financing, anti-trust approvals and due diligence. The board of directors of BOC
(the "Board") stated in the announcement that it had unanimously rejected the
proposal because of its preconditions and its failure to value fully the growth
prospects of BOC.

Later on 24 January 2006, Linde issued an announcement confirming its approach.
The announcement stated that the approach was friendly and that Linde would
continue to look for the support of the Board and BOC's management. It added
that the approach was based on an all cash offer at 1,500 pence per share and
was subject to a limited number of standard preconditions which Linde believed
could be readily satisfied. However, it made clear that there could be no
certainty that any offer would be made or that a transaction would result even
if the preconditions were satisfied or waived.

Having considered the announcement by Linde, the Board has not changed its view
and unanimously rejects the unsolicited preliminary proposal because of its
preconditions and its failure to value fully the growth prospects of BOC. The
Directors of BOC state their continuing confidence in the current strategy of
the group to deliver growth and excellent returns to its shareholders as an
independent company.

BOC shareholders need take no further action at this time.

Yours faithfully

/s/ Rob Margetts

Rob Margetts
Chairman

                                                                  Page 33 of 38





The directors of BOC accept responsibility for the information contained in this
letter. To the best of the knowledge and belief of the directors, (who have
taken all reasonable care to ensure that such is the case), the information
contained in this letter for which they accept responsibility is in accordance
with the facts and does not omit anything likely to affect the import of such
information.

Dealing Disclosure Requirements

Under the provisions of Rule 8.3 of the City Code on Takeovers and Mergers (the
"Code"), if any person is, or becomes, "interested" (directly or indirectly) in
1% or more of any class of "relevant securities" of BOC all "dealings" in any
"relevant securities" of that company (including by means of an option in
respect of, or a derivative referenced to, any such "relevant securities") must
be publicly disclosed by no later than 3.30 pm (London time) on the London
business day following the date of the relevant transaction.This requirement
will continue until the date on which the offer becomes, or is declared,
unconditional as to acceptances, lapses or is otherwise withdrawn or on which
the "offer period" otherwise ends. If two or more persons act together pursuant
to an agreement or understanding, whether formal or informal, to acquire an
"interest" in "relevant securities" of BOC, they will be deemed to be a single
person for the purpose of Rule 8.3.

Under the provisions of Rule 8.1 of the Code, all "dealings" in "relevant
securities" of BOC by Linde AG, or by any of their respective "associates", must
be disclosed by no later than 12.00 noon (London time) on the London business
day following the date of the relevant transaction.

A disclosure table, giving details of the companies in whose "relevant
securities" "dealings" should be disclosed, and the number of such securities in
issue, can be found on the Takeover Panel's website at
www.thetakeoverpanel.org.uk.

"Interests in securities" arise, in summary, when a person has long economic
exposure, whether conditional or absolute, to changes in the price of
securities. In particular, a person will be treated as having an "interest" by
virtue of the ownership or control of securities, or by virtue of any option in
respect of, or derivative referenced to, securities.

Terms in quotation marks are defined in the Code, which can also be found on the
Panel's website. If you are in any doubt as to whether or not you are required
to disclose a "dealing" under Rule 8, you should consult the Panel.

Forward Looking Statements

This letter includes `forward-looking statements' under United States securities
laws. These include, without limitation, those concerning BOC's current strategy
and growth prospects, as well as statements typically containing words such as
"intends", "expects", "anticipates", "targets", "estimates" and words of similar
import. By their nature, forward-looking statements involve risk and uncertainty
because they relate to events and depend on circumstances that will occur in the
future. There are a number of factors that could cause actual results and
developments to differ materially from those expressed or implied by such
forward-looking statements. These factors include, but are not limited to,
changes in economic conditions, changes in the level of capital investment by
the semiconductor industry, success of business and operating initiatives and
restructuring objectives, customers' strategies and stability, changes in the
regulatory environment, fluctuations in interest and exchange rates, the outcome
of litigation, government actions and natural phenomena such as floods,
earthquakes and hurricanes. Other unknown or unpredictable factors could cause
the company's actual results to differ materially from those in the
forward-looking statements. BOC does not undertake any obligation to update
publicly or revise forward-looking statements, whether as a result of new
information, future events or otherwise, except to the extent legally required.

The BOC Group plc (the Company) has been notified of the disposal on 30 January
2006 of 59,991 Ordinary shares of 25p each in the Company at an average exercise
price of 971.65p per share by Ogier Trustee (Jersey) Limited (the Trustee) as
trustee of The BOC Group plc Employee Share Trust (1995) (the Trust). These

Following this disposal of 59,991 Ordinary shares, the Trustee now holds

Trust in satisfaction of options granted to him in respect of these Ordinary
shares.
