[THE BOC GROUP logo] Registered Office: Chertsey Road Windlesham Surrey GU20 6HJ Registered in England No. 22096 17 March 2006 To the holders of BOC Ordinary shares and, for information only, to the holders of 12 1/4% Unsecured Loan Stock 2012/17 and participants in BOC share option schemes. Dear Shareholder Pre-conditional recommended cash offer for BOC by Linde AG On 30 January 2006 I wrote to you concerning the announcement made on 24 January 2006 that BOC had received an unsolicited preliminary proposal from Linde AG ("Linde"). The Board of directors of BOC (the "Board") stated in the announcement that it had unanimously rejected the proposal because of its pre-conditions and its failure to value fully the growth prospects of BOC. Linde also issued an announcement on 24 January 2006 that confirmed its approach and sought the support of the BOC Board for a proposal that was based on an all cash offer of 1,500 pence per share. After considering Linde's announcement and having regard to both the price being offered and the lack of certainty that a transaction would complete, the Board re-stated its unanimous rejection of the proposal at the AGM. Since then Linde has improved its proposal in terms of the price to be offered and has clarified the availability of finance and the viability of its strategy to obtain the critical regulatory approvals. On 6 March the Boards of directors of Linde and BOC announced (the "Announcement") that they had reached agreement on the terms of a pre-conditional recommended cash offer by Linde for the entire issued and to be issued share capital of BOC (the "Offer"). This letter contains a summary of certain key issues set out in the Announcement. A copy of the full Announcement is available on our website (www.boc.com). ----------- Page 2 of 7 The terms and conditions of the Offer Under the terms of the Offer, BOC shareholders will receive 1,600 pence in cash for each BOC Share and BOC ADS holders will receive 3,200 pence in cash for each BOC ADS (each BOC ADS representing two BOC Shares). The Offer values BOC's existing issued share capital at approximately (pound)8.2 billion. It is intended that the Offer, the making of which will be subject to certain pre-conditions referred to below being satisfied, will be implemented by way of a Court-approved scheme of arrangement under section 425 of the Companies Act (the "Scheme"). A Loan Note alternative (interest-bearing debt securities) will also be made available to all BOC shareholders other than to those in the United States, Canada, Australia or Japan (unless an exemption under the relevant securities laws is applicable). This may improve the tax position for some shareholders. Shareholders should take advice on this from their financial advisers in due course. The Offer will not be made until regulatory clearances have either been obtained from both US and European competition authorities or until such pre-conditions have been waived by Linde. If these pre-conditions have not been satisfied by 31 May 2006, BOC will be permitted to pay a second interim dividend to BOC shareholders, up to a maximum amount of 27 pence per BOC Share. If payable, the amount of the dividend would be equal to 3.375 pence per BOC Share for each consecutive period of seven days (but will not accrue for part of such a period) during the period commencing 1 June 2006 and ending on the earlier of (a) 26 July 2006 and (b) the date on which Linde announces the satisfaction of the pre-conditions. If the pre-conditions have been satisfied by 31 May 2006, no part of the dividend will either accrue or be paid. Timing It is expected that the Scheme document and proxy form will be posted to BOC shareholders shortly after the satisfaction or waiver of the regulatory pre-conditions. It is not yet possible to give an indication of when this will be achieved. Linde is confident that the pre-conditions will be satisfied in a timely manner, subject to agreement with the appropriate authorities on reasonable divestments. Background to the Board's decision BOC is one of the world's leading industrial gases companies. BOC's strong financial performance over recent years has produced consistent improvements in its return on capital employed and, with its excellent team of employees driving the business, has delivered significant value to BOC shareholders. In assessing Linde's proposal, the BOC Board has had regard to both the price being offered and the likelihood that a transaction would complete. The BOC Board, which has been so advised by JPMorgan Cazenove and Merrill Lynch, considers the terms of the Offer to be fair and reasonable. In providing their advice, JPMorgan Cazenove and Merrill Lynch have taken into account the commercial assessments of the directors of BOC. The Offer is materially more attractive than Linde's initial proposal and represents a significant premium to the BOC share price prior to the approach from Linde; a premium of approximately 40 per cent. to the average closing price of 1,143 pence per BOC Share during the three months up to and including 23 January 2006 (being the last business day prior to the announcement by BOC that it had received an approach from Linde). In the view of the BOC Board it is a full and fair price, taking into account the prospects for the BOC business and the strategic options available to the BOC Group. In light of the financing arrangements which Linde has made and its plans to address any concerns raised by competition authorities, the BOC Board believes that this is an offer that will ultimately be delivered to BOC shareholders. Accordingly, the BOC Board intends to recommend that BOC shareholders vote in favour of the Scheme, which it considers to be in the best interests of BOC shareholders as a whole. Rationale for the combination The transaction provides the opportunity for Linde and BOC to create a leading worldwide focused industrial gases business with combined gas and engineering sales of around (euro)11.9 billion. The combination of Linde and BOC would result in a much larger, global gas player with complementary Page 3 of 7 products and geographic positions. Such a combination would be very well positioned in the key high growth products and regions of the gases industry and would be better able to serve its customers worldwide. In addition to the improved growth prospects of the enlarged group, Linde believes the combination creates an opportunity to deliver synergies through the combined group, prior to any one-off expenses, of approximately (euro)250 million per annum, to be fully realised during 2009. These synergies are expected to be predominantly based on joint supply management optimisation and combined procurement volumes and a reduction in selling, general and administrative expenses. Through a rapid but smooth integration and transformation, as well as the mutual exchange of best practices in all functions, regions and market segments, the combined group will strive to unlock value opportunities for shareholders, customers and employees. Linde believes that the acquisition will further enhance its proven capability to execute a profitable growth strategy and is expected to be accretive in terms of earnings per share during 2008. Management, employees and pensions Linde attaches great importance to the skills and experience of the existing management and employees of BOC. Linde and BOC's businesses are very complementary on a geographic basis and Linde expects that BOC managers and employees will play an important role in the enlarged group as well as benefiting from greater opportunities within it. Accordingly, it is Linde's intention to employ the best talents in the combined group. Further, Linde has confirmed that the existing employment rights, including pension rights, of all employees of BOC will be fully safeguarded. Linde, BOC and the trustees of the BOC UK Defined Benefit Pension Schemes (having regard to the interests of active, deferred and retired members) have reached agreement in respect of BOC's obligations in relation to the funding of such schemes following completion of the Offer and the agreement has been cleared by the Pensions Regulator. Share options Participants in BOC Group's share schemes will be contacted regarding the effect of the Offer on their rights and appropriate proposals will be made to participants in due course (including a cashless exercise facility). Details of these proposals will be set out in the Scheme document and in documents to be sent to option holders. Overseas shareholders The availability of the Offer to shareholders resident in a country outside the UK may be affected by the laws of that country. Shareholders who are not resident in the UK should inform themselves about and observe any applicable requirements. What happens next? Further information will be contained in the Scheme document when posted, subject to fulfilment or waiver of the pre-conditions of the Offer, and until then there is no action that BOC shareholders can take.
