        exercise or enforcement thereof of any other right on any other
        occasion. Both Parties agree to contract in good faith and following
        good business practices.

Date:  23 February 2004

Mr G Dawson

Dear Guy

The following sets out the principal terms of your appointment as a
non-executive director of The BOC Group plc ("the Company"). Nick Deeming,
Company Secretary, will be in touch shortly to make arrangements with you for
your induction programme:

1.   TERM OF OFFICE

Your appointment as a non-executive director of the Company will, subject to
completion of satisfactory due diligence, be effective from 1 March 2004 and is
on the terms, and subject to, the conditions of the Company's Articles of
Association. Accordingly, it may be terminated pursuant to the terms of the
Articles.

You will initially hold office until the next Annual General Meeting which is to
be held on 14 January 2005 and you shall then be eligible for re-election by the
shareholders. Your term of office will then expire when you retire by rotation
in accordance with the Articles of Association, currently expected to be at the
Annual General Meeting in 2008. At that time, however, it may be agreed by you
and the Board that you stand for re-election by the shareholders for a second
term. At any time during your appointment, your appointment may be terminated by
either you or the Company giving to the other not less than one month's written
notice.

On termination of your appointment, you undertake to resign from all offices
held by you in any companies forming part of The BOC Group.

As a non-executive director you are not an employee of the Company and, for the
avoidance of doubt, you accept and agree that you will have no claims against
the Company or any company forming part of The BOC Group (each a "Group
Company") on termination of your appointment subject only to the terms set out
in paragraph 3 below.

2.   DUTIES

Your duties as a non-executive director include, but are not limited to,
attendance at all Board meetings, the Annual General Meeting and meetings of
board committees to which you are appointed. You may also be requested to attend
meetings with third parties.

The schedule of Board meeting dates for the remainder of 2004 is attached
(Appendix 1). You will note that one board meeting each year is held at an
overseas BOC site location, with another held at a business site in the UK. The
remaining meetings are held at the corporate head office in Windlesham. The
Annual General Meeting is normally held on the third Friday in January in
London.

You are invited to become a member of the Remuneration Committee which meets
immediately prior to most Board meetings, a member of the Audit Committee which
meets four times a year and a member of the Nomination Committee which meets at
least once a year but also as required.

We would anticipate a time commitment of a minimum of 20 days per annum after
your induction programme, to enable you to fulfil your duties. You have
indicated that you consider you have sufficient time to devote to your BOC
duties when taken with your other business commitments.

                                     - 1 -
<PAGE>

Should your commitments change during your term of office you should advise
either myself or Nick Deeming as soon as practicable.

At all times you will use your best endeavours to promote the interests of the
Company. You should note that the Company currently maintains indemnity
insurance for its directors, details of which are available from the Company
Secretary.

3.   FEES AND EXPENSES

Non-executive director fees will be paid at the rate of Pound Sterling40,000 per
annum of which Pound Sterling10,000, after tax, will, pursuant to an agreed
process, be invested in The BOC Group plc Ordinary shares. This sum will be
deemed to accrue from day to day, will be payable in equal monthly instalments
in arrears and is subject to deductions of national insurance and income tax
under the Inland Revenue PAYE regulations. You will also be reimbursed by the
Company for all expenses necessarily incurred in performing your duties.

4.   INDEPENDENT PROFESSIONAL ADVICE

You may also claim the reasonable costs of any independent professional advice
which you, with or without other directors of the Company, have properly taken
in the best interests of the Company as to the nature or ambit of your duties as
a non-executive director. In any such case you should discuss the issues with me
in advance, or if this is not deemed appropriate, then with one or more of your
non-executive colleagues. A brief summary of the subject matter on which you
intend to seek advice, and the name of the proposed advisers, should also be
first furnished to the Company Secretary. Thereafter, the advice when obtained
by you should be made available to your other directors.

5.   CONFIDENTIAL INFORMATION

At all times during, and after the termination, of your appointment as a
director of the Company you must not use for your own purposes or for another's
benefit or disclose to any third party any confidential information about The
BOC Group.

Confidential information means details about the business, prospective business,
technical processes, computer software, intellectual property rights or finances
of The BOC Group, or any combinations of these matters, including without
limitation, price lists, details of customers and suppliers, information
relating to research and development, marketing strategies and tactics which may
come into your possession by virtue of your appointment and which the Company
regards, or could reasonably be expected to regard as confidential, whether or
not such information is marked as such.

All confidential information and all other documents, papers and property
relating thereto (on whatever media or wherever located) which may have been
made or prepared by you, or at your request or have come into your possession or
under your control in the course of your appointment or which relate in any way
to The BOC Group, the business (including prospective business) or affairs of
The BOC Group or of any customer, supplier, agent distributor or sub-contractor
of The BOC Group shall as between the Company and you be deemed to be the
property of the Company. You will return to the Company all such documents and
other property including all copies immediately upon the termination of your
appointment or at any earlier time on demand.

You will immediately inform the Company if you become aware of the possession,
use or knowledge of any confidential information by any person not authorised to
possess, have use or knowledge of that information, whether during or after your
appointment and will, at the Company's request, provide such reasonable
assistance as is required to deal with such an event.

                                     - 2 -
<PAGE>

All such confidential information should not be disclosed unless or until it
enters the public domain, other than by breach of the terms of this letter, is
obtained from a third party who is lawfully authorised to disclose such
information, or is authorised for release by prior written consent of the Board.
Notwithstanding this, you are not prevented from disclosing confidential
information where it is required to be disclosed by law or any regulatory or
government authority.

6.   REGULATORY REQUIREMENTS

It is a requirement under the Companies Act 1985 for a company to maintain a
register showing certain personal particulars of its directors. These details
must also be filed with the Registrar of Companies.

A Register of Directors' Interests must also be maintained pursuant to the
Companies Act 1985. Any interests held by you or connected persons in the shares
and options of the Company must be recorded. All changes to these interests must
also be notified to the Company and recorded throughout your directorship of the
Company. A more detailed overview of the requirements of the UK Companies Act
and UK Listing Authority is contained in section 21 of the attached folder.

A personal details form is enclosed for your completion (Appendix 2) which will
provide all the necessary information to comply with the various regulations.
When completed return the form to our Company Secretarial Department.

The information will be used to make the necessary declarations and register
entries and to produce the Form 288(a) which will be sent to you for signature
to indicate your consent to act as a director. This form will then be filed with
the Registrar of Companies. This must be done within 14 days of the date of your
appointment.

Attached is a copy of the Directors' Reference Binder which contains information
likely to be useful to you in connection with your appointment as a director of

You will initially hold office until the next Annual General Meeting which is to

On termination of your appointment, you undertake to resign from all offices
held by you in any companies forming part of The BOC Group.

intend to seek advice, and the name of the proposed advisers, should also be
first furnished to the Company Secretary. Thereafter, the advice when obtained
by you should be made available to your other directors.

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.

<PAGE>

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.

Yours sincerely

Rob Margetts
