Page 1 of 3 THE BOC GROUP plc ANNOUNCEMENT RELEASED TO A REGULATORY INFORMATION SERVICE ON 11 JULY 2006 AT 07.36 HRS UNDER REF: PRNUK-1107060729-760B 11 July 2006 NOTIFICATION OF COMPLAINT BY CELANESE The BOC Group plc ("BOC") has been informed by Celanese Corporation that it has lodged a complaint against BOC in the District Court of Dallas County, Texas, relating to the development by Celanese Corporation and Celanese (Nanjing) Chemical Co., Ltd. ("Celanese") of a new acetic acid manufacturing plant in Nanjing, China and associated industrial gas supply arrangements. The amounts claimed are USD 250 million for compensatory damages and an additional amount in exemplary damages, suggesting a total of not less than USD 960 million. Celanese has not served the complaint on BOC. BOC believes the case to be completely without merit and it will vigorously defend it. BOC notes the timing of this complaint and that Celanese gave no indication of a proposed claim prior to its notification of intended legal action. Following notification of the above, Linde AG has informed BOC that it expects the final pre-condition to the offer (which relates to anti-trust) by Linde AG for BOC to be satisfied within the next month and that the scheme document will be despatched to BOC shareholders immediately thereafter. The consent of the High Court to the despatch of the scheme document has been obtained. Completion of the offer is still expected to take place in the third calendar quarter of 2006.

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, www.boc.com, and on the SEC's website, www.sec.gov. 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.
