securities. BOC Shareholders are advised to read carefully the formal
documentation in relation to the offer by Linde AG once it has been despatched.

This announcement includes 'forward-looking statements' under United States
securities laws. These include, without limitation, those concerning the outcome
of pending and threatened litigation, the completion of the offer, as well as
statements typically containing words such as "intends", "expects", "believes",
"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. More detailed information about certain of these factors is
contained in BOC's filings with the United States Securities and Exchange
Commission (SEC), including its annual report on Form 20-F, which are available
on BOC's website,, and on the SEC's website, Other
unknown or unpredictable factors could cause 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.
