Yours sincerely /s/ Rob Margetts Chairman encs I acknowledge, and agree to, the principal terms of my appointment as a non-executive director of The BOC Group plc as set out above. Signed: /s/ CJ O'Donnell Date: 24/5/04 - 4 - 1 June 2004 Mr A E Isaac [Address] Dear Tony I refer to the resolution of the Board on 11 May 2004 whereby it was agreed to vary your contract as set out below. Accordingly I can confirm that your contract dated 19 November 2002, including a side letter of the same date, is hereby varied so that "Retirement Age" as defined in clause 11.4 shall be amended to "the conclusion of the Annual General Meeting in 2007". Clause 11.2 (b) and 11.4 of your contract, as varied by this letter, will now read: 11.2 (b) Paying the Executive at any time a sum in lieu of the unexpired portion of the Notice Period. Such sum shall be equivalent to the salary payable under paragraph 3.1 of this Agreement, bonus (payable by reference to the average of actual Variable Compensation Plan (VCP), bonus payments, if any, over the previous two financial years) and a cash allowance in lieu of company car (each pro-rata to the unexpired portion of the notice period), and enhancing the pension benefits payable to or in respect of the Executive by calculating those benefits as if the Executive's pensionable service terminates at the end of the period by reference to which salary in lieu is paid. 11.4 The Employment shall terminate in any event without notice upon the conclusion of the Annual General meeting in 2007 (the "Retirement Date"). If the Retirement Date occurs prior to the expiry of the Notice Period, then the Executive will only be entitled to receive such notice (or payment in lieu of notice) for the period up to that date. The Employment may be extended beyond the Retirement Date by prior mutual agreement between the Company and the Executive. Additionally, in respect to the matters set out in my letter to you dated 19 November 2002 I propose recommending the following to the Remco to ensure your remuneration remains competitive. 1. Long Term Incentive Plan I will recommend that you will continue to receive allocation of not less than 150% of your base salary for the issues planned in February 2005 and February 2006, subject to the normal performance conditions. Under the rules of the scheme, these awards will vest subject to any performance conditions being satisfied and proportional payment will be made to reflect the number of whole months of the performance period of each award which have elapsed at the date of your retirement. Please note any payments due will be made at the end of each LTIP period. 2. Exercise of outstanding ESOS Awards I confirm any outstanding options you hold at the time of your retirement will remain in force up to 31 January 2009. Rules for the ESOS (1995 Scheme) requires that, in the case of retirement, performance conditions must be met before awards become eligible for exercise and that awards must be held for 3 years before being eligible for exercise. Rules for the ESOS (2003 Scheme) provides for pro-rata award based on number of months the award has been held at time of retirement, subject to performance conditions being met. Please note any grants due under the 2003 Scheme will be made at the end of each ESOS award period. 3. Other Performance Incentive As you are aware, the Remuneration Committee is considering the introduction of new/enhanced incentive schemes. I, hereby, confirm that it is intended that you would participate in these up to the date of the Annual General Meeting in 2007, subject to the rules of the scheme as approved by shareholders at the 2005 Annual General Meeting.
