       of the Works in the name of the Company or the Company's nominee.

12.5   The Executive shall from time to time, both during his employment under
       this Agreement and thereafter, at the request and expense of the Company,
       promptly do all things and execute all documents necessary or desirable
       to give effect to the provisions of this Clause 12 including, without
       limitation, all things necessary to obtain and/or maintain patent or
       other protection in respect of any Works in any part of the world and to
       vest such rights (including, without limitation, all IPRs) in and to the
       Works in the Company or the Company's nominee.

12.6   For the avoidance of doubt, the provisions of this Clause 12 shall apply
       to any rights (including, without limitation, any IPRs) in the Works
       arising in any jurisdiction, and the provisions of this Clause 12 shall
       apply in respect of any jurisdiction to the extent permitted by the
       directives, statutes, regulations and other laws of any such
       jurisdiction.

13.    CONFIDENTIALITY

13.1   The Executive shall not (other than in the proper performance of his
       duties or without the prior written consent of the Board or unless
       ordered by a court of competent jurisdiction) at any time either during
       the continuance of his employment hereunder or after its termination
       disclose or communicate to any person or use for his own benefit or the
       benefit of any person other than the Company or any Associated Company
       any confidential information which may come to his knowledge in the
       course of his employment hereunder concerning the business or finances of
       any member of the Group or of any of its suppliers, agents, distributors
       or customers and the Executive shall during the continuance of his
       employment hereunder use his best endeavours (and following any
       termination thereof his reasonable endeavours) to prevent the
       unauthorised publication or misuse of any confidential information
       provided that such restrictions shall cease to apply to any confidential
       information which may enter the public domain other than through the
       default of the Executive but in any event the restrictions in this Clause
       13.1 shall remain in full force and effect for so long as the Executive
       is in a position to utilise such information more readily than persons
       who have not been employed by the Company or its Associated Companies.

13.2   All notes and memoranda of any trade secret or confidential information
       concerning the business of the Company or the Associated Companies or any
       of its or their suppliers, agents, distributors, customers or others
       which shall have been acquired, received or made by the Executive during
       the course of his employment shall be the property of the Company and
       shall be surrendered by the Executive to someone duly authorised in that
       behalf at the termination of his employment or at the request of the
       Board at any time during the course of his employment.

13.3   Without prejudice to the generality of Clause 13.1 the following is, for
       the avoidance of doubt, a non-exhaustive list of matters which in
       relation to the Company and the Associated Companies are considered
       confidential and must be treated as such by the Executive (for the
       purposes of this Agreement):

              customers; and

       (d)    any invention, technical data, know-how, instruction or operations
              manual or other manufacturing or trade secrets of the Group and/or
              their clients/customers.

13.4   The Executive shall comply with any reasonable policy produced by the
       Company concerning the Executive's ability to either directly or

       television transmission or communicate with any representative of the
       media or any third party relating to the business or affairs of the
       Company or any Associated Company or to any of its or their officers,
       employees, customers/clients, suppliers, distributors, agents or

              the event of his failure to do so the Company is hereby
              irrevocably authorised to appoint some person in his name and on
              his behalf to sign and deliver such resignations to the Board
              and/or to each such Associated Company;

                                       12

       (d)    shall not at any time thereafter use the name "Shire" or any name

              any such debts or loans.

14.4   If the employment of the Executive under this Agreement is terminated by
       reason of the liquidation of the Company for the purpose of
       reconstruction or amalgamation or as part of any arrangement for the
       amalgamation or reconstruction of the Company not involving insolvency
       and the Executive is offered employment with any concern or undertaking
       resulting from the reconstruction or amalgamation on terms and conditions
       which taken as a whole are not less favourable than the terms of this
       Agreement then the Executive shall have no claim against the Company in
       respect of such termination.

15.    EXECUTIVE'S COVENANTS

15.1   The Executive acknowledges that during the course of his employment with
       the Company he will receive and have access to confidential information
       of the Company and its Associated Companies (including without limitation
       those matters specified in Clause 13.3 of this Agreement) and he will
       also receive and have access to detailed client/customer lists and
       information relating to the operations and business requirements of those
       clients/customers and accordingly he is willing to enter into the
       covenants described in this Clause 15 in order to provide the Company and
       its Associated Companies with what he considers to be reasonable
       protection for those interests.

15.2   In this Clause 15:

       (a)    "RESTRICTED BUSINESS" means the Business of the Company and its
              Associated Companies at the time of the termination of the
              Executive's employment with which the Executive was involved to a
              material extent at any time during the period of 12 (twelve)
              months ending on the Restriction Date and for the purposes of this
              Clause the term "Business" shall mean the research, development,
              marketing, sale or supply of pharmaceuticals for administration to
              humans;

       (b)    "RESTRICTED CUSTOMER" means any firm, company or other person who,
              at any time during the period of 12 (twelve) months ending on the
              Restriction Date, was a customer of or in the habit of dealing
              with the Company or any Associated Company and with whom the
              Executive dealt to a material extent or for whom or which the
              Executive was responsible on behalf of the Company or any
              Associated Company during that period and in respect of such
              customer material damage to the interests of the Company or any

<PAGE>
                                       13

              Associated Company could occur if such customer ceased or reduced
              its business with the Company or any Associated Company;

       (c)    "RESTRICTED EMPLOYEE" means any person who, at the Restriction
              Date was employed by the Company or any Associated Company at a
              senior level and who could materially damage the interests of the
              Company or any Associated Company if he became employed in any
              business concern in competition with the Restricted Business and
              with whom the Executive worked closely or about whom the Executive
              obtained material detailed information, in either case at any time
              during the period of 12 (twelve) months ending on the Restriction
              Date; and

       (d)    "RESTRICTION DATE" means the date of termination of this
              Agreement.

15.3   The Executive will not, for a period of 12 (twelve) months after the
       Restriction Date, solicit or endeavour to entice away from the Company or
       any Associated Company the business or custom of a Restricted Customer
       with a view to providing or receiving goods or services to or from that
       Restricted Customer in competition with any Restricted Business.

15.4   The Executive will not, for a period of 12 (twelve) months after the
       Restriction Date, provide goods or services to or otherwise have any
       business dealings with any Restricted Customer in the course of any
       business concern which is in competition with any Restricted Business.

15.5   The Executive will not, for a period of 12 (twelve) months after the
       Restriction Date, in the course of any business concern which is in
       competition with any Restricted Business offer employment to or otherwise
       endeavour to entice away from the Company or any Associated Company any
       Restricted Employee.

15.6   The Executive will not, without the prior written consent of the Board,
       for a period of 6 (six) months after the Restriction Date, be engaged in
       or concerned in any capacity in any business concern which is or might
       reasonably be expected to be in competition with any Restricted Business.
       This Clause shall not restrain the Executive from being engaged or
       concerned in any business concern in so far as the Executive's duties or
       work shall relate solely:

       (a)    to geographical areas where the business concern is not in
              competition with the Restricted Business; or

       (b)    to services or activities of a kind with which the Executive was
              not concerned to a material extent during the period of 12
              (twelve) months ending on the Restriction Date.

15.7   The obligations imposed on the Executive by this Clause 15 extend to him
       acting not only on his own account but also on behalf of any other firm,
       company or other person and shall apply whether he acts directly or
       indirectly.

<PAGE>
                                       14

15.8   The Executive hereby agrees that he will at the request and expense of
       the Company enter into a direct agreement or undertaking with any
       Associated Company whereby he will accept restrictions and provisions
       corresponding to the restrictions and provisions in this Clause 15 (or
       such of them as may be appropriate in the circumstances) in relation to
       such activities and such area and for such a period not exceeding 12
       (twelve) months as such Associated Company may reasonably require for the
       protection of its legitimate business interests.

15.9   It is agreed between the parties that whilst the restrictions set out in
       this Clause 15 are considered fair and reasonable for the protection of
       the Company's business and trade secrets, if it should be found that any
       of the restrictions be void as going beyond what is fair and reasonable
       in all the circumstances and if by deleting part of the wording or
       substituting a shorter period of time or different geographical limit or
       a more restricted range of activities for any of the period of time,
       geographical limits or ranges or activities set out in this Clause 15 it
       would not be void then there shall be substituted such next less
       extensive period and/or limit and/or activity or such deletions shall be
       made as shall render this Clause 15 valid and enforceable.

16.    CHANGE OF CONTROL

16.1   For the purposes of this Clause 16:

       (a)    "RELEVANT EVENT" means either:

              (i)    the termination by the Company of the Executive's
                     employment (other than for cause in accordance with Clause
                     14 of this Agreement); or

              (ii)   the Executive's resignation where such resignation is as a
                     consequence of a repudiatory breach of contract by the
                     Company and amounts to a constructive dismissal,

              within the period of 12 (twelve) months following the date of a
              Change of Control.

       (b)    Subject to Clause 16.6 below "Change of Control" means where any
              person either alone or together with any person acting in concert

              of the Income and Corporation Taxes Act 1988.

16.2   If a Relevant Event occurs the Company shall pay to the Executive within
       14 (fourteen) days of that Relevant Event a sum equal to the aggregate
       of:

              of 1 (one) year; and

       (b)    an amount in lieu of annual bonus to be decided at the absolute

              (one) year; and

       (d)    an amount in respect of the actual cost to the Executive of the
              provision of the benefits due under Clauses 7 and 8 of this
              Agreement for the period of notice to the Executive.

16.3   Subject to any rights accrued at the date of termination of the
       Executive's employment under the provisions of any pension scheme of the
       Company, any payment by the Company pursuant to this Clause 16 shall be
       made in full and final settlement of all and any claims arising from or
       in connection with the Executive's employment or its termination or his
       office as Group Finance Director and its loss in each case in respect of
       the Company or any Associated Companies.

16.4   All payments to be made pursuant to this Clause 16 shall be paid less any
       necessary withholdings.

16.5   The Executive hereby agrees that he shall not, following a payment under
       this Clause 16, bring any claim before any court or employment tribunal
       relating to unfair dismissal.

16.6   This Clause shall not apply where in connection with a scheme of
       reconstruction or amalgamation or reorganisation of the Company and one
       or more of its Associated Companies the Executive refuses an offer of
       employment on terms identical in all material respects to those hereunder
       by the company which following such reconstruction or reorganisation
       replaces the Company or the relevant Associated Companies.

17.    DISCIPLINARY AND GRIEVANCE PROCEDURES

17.1   The Executive shall be expected to maintain the highest standard of
       integrity and behaviour. For the purpose of disciplinary and grievance

       terminate the Executive's employment under this Agreement and such
       termination shall be without prejudice to any claim which the Executive
       may have for damages for breach of this Agreement provided that the
       Company was not entitled at the time of such removal or failure to
       re-elect to terminate his employment pursuant to Clause 14.1.

19.    DATA PROTECTION

       The Executive consents to the Company or any Associated Company holding

         terminate the employment of the Executive with immediate effect by
         paying to the Executive (less deductions as appropriate) salary in

                  Executive's employment hereunder) for his use and that of his
                  spouse (if any) during the continuance of his employment in
                  respect of which the Company shall pay or reimburse the
                  Executive all business and reasonable private petrol and the
                  standing and running costs together with all insurance and
                  maintenance costs; or

         8.1.2    the sum of (pound)10,560 per annum (payable in 12 (twelve)
                  monthly instalments on the date the Executive's salary is
                  paid less any deductions the Company is required to make by
                  law) (which shall increase in line with the retail price
                  index) to enable the Executive to purchase, maintain,
                  comprehensively insure and tax a car for his use during the
                  continuance of his employment, together with reimbursement of
                  all business and reasonable private petrol. No election may
                  be made under this Clause 8.1.2 where a car has been provided
                  under Clause 8.1.1 until the expiration of the lease term of
                  the car in question.

8.2      The Executive shall at all times and in all respects conform to and
         comply with any policy which may from time to time be made by the
         Company and notified in writing to the Executive in relation to cars
         provided by it for the use of its employees and in particular the
         Executive:

         (a)      shall ensure that at all times when the car is driven on a
                  public highway it is in the state and condition required by
                  law and that a current MOT test certificate is in force in
                  respect of it (if appropriate); and

         (b)      shall at all times be the holder of a current driving licence
                  entitling him to drive motor cars in the United Kingdom and
                  shall produce it to the Company upon request.

8.3      Where Clause 8.1.1 applies the Company shall replace the car with
         another of similar make and model at such intervals as the
         Remuneration Committee may in its discretion decide.

8.4      For the avoidance of doubt the Company shall be entitled at its
         absolute discretion to withdraw the use of the car provided pursuant
         to this Clause in circumstances reasonably provided for in the
         Company's car policy in force from time to time.

8.5      For all purposes connected with or relating to the employment of the
         Executive the benefit of the private use of the car(s) provided
         pursuant to this Agreement shall be calculated in accordance with the
         Inland Revenue rules in force from time to time.

8.6      The Executive shall take good care of the car and ensure that the
         provisions and conditions of any insurance policy relating to it are
         observed and shall return the car and its keys to the Company at its
         registered office (or any other place the Company

<PAGE>
                                       7

         may reasonably nominate) immediately upon the termination of his
         employment hereunder.

9.       EXPENSES

         The Company shall during the continuance of his employment reimburse
         the Executive in respect of all reasonable travelling, accommodation
         and other similar out-of-pocket expenses properly incurred by him in
         or about the performance of his duties under this Agreement as
         approved by the Board provided that the Executive if so required by
         the Company provides reasonable evidence of any expenditure in respect
         of which reimbursement is claimed.

10.      HOLIDAYS

10.1     The Executive shall (in addition to the usual public and bank
         holidays) be entitled during the continuance of his employment to 25
         (twenty-five) working days' paid holiday in each holiday year, or such
         greater number in accordance with the Company's policy from time to
         time to be taken at a time or times as shall be convenient to the
         Company.

10.2     The Executive shall not be entitled to carry forward any annual
         holiday entitlement not taken by him for any reason from one holiday
         year to the next without the prior written consent of the Board (such
         consent not to be unreasonably withheld).

10.3     Upon the termination of his employment the Executive's entitlement to
         accrued holiday pay (which accrues at the rate of 2.08 days per month)
         shall be calculated on a pro rata basis in respect of each completed
         month of service in the holiday year in which his employment
         terminates and the appropriate amount shall be paid to the Executive
         in addition to payment in lieu for any holidays not taken in previous
         holiday years provided that if the Executive shall have taken more
         days holiday than his accrued entitlement the Company is hereby
         authorised to make an appropriate deduction from the Executive's final
         salary payment.

11.      INCAPACITY

11.1     Subject to his complying with the Company's procedures relating to the
         notification and certification of periods of absence from work as from
         time to time in force the Executive shall continue to be paid his
         salary (inclusive of any statutory sick pay or social security
         benefits to which he may be entitled) during any periods of absence
         from work due to sickness, injury or other incapacity incapacitating
         the Executive from attending to his duties up to a maximum of 26
         (twenty-six) weeks in aggregate in any period of 52 (fifty-two)
         consecutive weeks.

11.2     If the Executive shall have been absent from work due to sickness,
         injury or other incapacity for a continuous period of 26 (twenty-six)
         weeks or more then he shall receive such benefits (if any) as are
         available to him under the terms of the Company's permanent health
         insurance scheme or such greater sum (if any) as the Board may in its
         absolute discretion decide.

<PAGE>
                                       8

11.3     If any incapacity of the Executive shall be or appear to be caused by
         any alleged action or wrong of a third party and the Executive shall
         decide to claim damages in respect thereof, then the Executive shall
         use all reasonable endeavours to recover damages for loss of earnings
         over the period for which salary has been or will be paid to him by
         the Company under Clause 11.1, and shall account to the Company for
         any such damages recovered (in an amount not exceeding the actual
         salary paid or payable to him by the Company under Clause 11.1 in
         respect of the said period) less any costs borne by him in achieving
         such recovery.

         The Executive shall keep the Company informed of the commencement,
         progress and outcome of any such claim.

12.      INTELLECTUAL PROPERTY

12.1     For the purposes of this Clause 12 the term "IPRs" means any and all

         registered design rights, trade and business names, copyrights
         (including copyright in software), database rights, topography rights
         and all other intellectual property rights (whether or not any of
         these is registered and including applications for registration of any
         such thing) and all rights or forms of protection of a similar nature
         or having equivalent or similar effect to any of these which may
         subsist anywhere in the world.

12.2     If the Executive creates, makes, authors, originates, conceives or
         writes (either alone or with others) any works, designs, innovations,
         inventions, improvements, processes, get-ups or trade marks in the
         course of his employment with the Company ("Works"):

         (a)      the Executive will promptly disclose to the Company full
                  details of any such inventions, processes, improvements or
                  other Works;

         (b)      all rights (including, without limitation, all IPRs) in and
                  to such Works shall solely legally and beneficially vest in
                  the Company immediately upon their creation without any
                  payment to the Executive;

         (c)      the Executive hereby irrevocably and unconditionally waives,
                  in favour of the Company, its licensees and
                  successors-in-title any and all moral rights conferred on the
                  Executive in relation to the Works (existing or future); and

         (d)      the Executive shall not knowingly do anything, or omit to do
                  anything, to imperil the validity of any patent or
                  protection, or any application therefor, relating to any of
                  the Works.

12.3     To the extent such rights and IPRs do not so vest in the Company, the
         Executive hereby (i) assigns to the Company all future copyright,
         database rights and unregistered design rights in the Works and (ii)
         in respect of all other rights and IPRs agrees to assign to the
         Company all of the Executive's right, title and interest (including
         without limitation all IPRs) in the Works.

         attorney, and to make use of his name and to sign and execute any
         documents and/or perform any act on his behalf, for the purpose of
         giving to the Company the full benefit of the provisions of this
         Clause 12 and, where permissible, to obtain patent or other protection
         in respect of any of the Works in the name of the Company or the
         Company's nominee.

12.5     The Executive shall from time to time, both during his employment
         under this Agreement and thereafter, at the request and expense of the
         Company, promptly do all things and execute all documents necessary or
         desirable to give effect to the provisions of this Clause 12
         including, without limitation, all things necessary to obtain and/or
         maintain patent or other protection in respect of any Works in any
         part of the world and to vest such rights (including, without
         limitation, all IPRs) in and to the Works in the Company or the
         Company's nominee.

12.6     For the avoidance of doubt, the provisions of this Clause 12 shall
         apply to any rights (including, without limitation, any IPRs) in the
         Works arising in any jurisdiction, and the provisions of this Clause
         12 shall apply in respect of any jurisdiction to the extent permitted
         by the directives, statutes, regulations and other laws of any such
         jurisdiction.

13.      CONFIDENTIALITY

13.1     The Executive shall not (other than in the proper performance of his
         duties or without the prior written consent of the Board or unless
         ordered by a court of competent jurisdiction) at any time either
         during the continuance of his employment hereunder or after its
         termination disclose or communicate to any person or use for his own
         benefit or the benefit of any person other than the Company or any
         Associated Company any confidential information which may come to his
         knowledge in the course of his employment hereunder concerning the
         business or finances of any member of the Group or of any of its
         suppliers, agents, distributors or customers and the Executive shall
         during the continuance of his employment hereunder use his best
         endeavours (and following any termination thereof his reasonable
         endeavours) to prevent the unauthorised publication or misuse of any
         confidential information provided that such restrictions shall cease
         to apply to any confidential information which may enter the public
         domain other than through the default of the Executive but in any
         event the restrictions in this Clause 13.1 shall remain in full force
         and effect for so long as the Executive is in a position to utilise
         such information more readily than persons who have not been employed
         by the Company or its Associated Companies.

13.2     All notes and memoranda of any trade secret or confidential
         information concerning the business of the Company or the Associated
         Companies or any of its or their suppliers, agents, distributors,

         by the Executive during the course of his employment shall be the
         property of the Company and shall be surrendered by the Executive to
         someone duly authorised in that behalf at the termination of his
         employment or at the request of the Board at any time during the
         course of his employment.

13.3     Without prejudice to the generality of Clause 13.1 the following is,
         for the avoidance of doubt, a non-exhaustive list of matters which in
         relation to the Company and the Associated Companies are considered
         confidential and must be treated as such by the Executive (for the
         purposes of this Agreement):

         business or affairs of the Company or any Associated Company or to any
         of its or their officers, employees, customers/clients, suppliers,
         distributors, agents or shareholders or to the development or
         exploitation of Works or IPRs (as defined in Clauses 12.1 and 12.2).

                  any rights of the Executive arising as a result of the loss
                  of his employment hereunder, immediately resign without claim
                  for compensation from office as a director of the Company and
                  any Associated Company and from any other office held by him

                  prejudice to any claim he may have for damages for breach of
                  this Agreement) and in the event of his failure to do so the

                  person in his name and on his behalf to sign and deliver such

                  in any way connected with or interested in the business of

                  employee for the purpose of communicating with prospective
                  employers or complying with any applicable statutory
                  requirements);

<PAGE>
                                      12

         (d)      shall not at any time thereafter use the name "Shire" or any
                  name capable of confusion therewith (whether by using such
                  names as part of a corporate name or otherwise); and

         (e)      shall immediately repay all outstanding debts or loans due to
                  the Company or any Associated Company and the Company is
                  hereby authorised to deduct from any wages (as defined by
                  section 27 of the Employment Rights Act 1996) of the
                  Executive a sum equal to any such debts or loans.

14.4     If the employment of the Executive under this Agreement is terminated
         by reason of the liquidation of the Company for the purpose of
         reconstruction or amalgamation or as part of any arrangement for the
         amalgamation or reconstruction of the Company not involving insolvency
         and the Executive is offered employment with any concern or
         undertaking resulting from the reconstruction or amalgamation on terms
         and conditions which taken as a whole are not less favourable than the
         terms of this Agreement then the Executive shall have no claim against
         the Company in respect of such termination.

15.      EXECUTIVE'S COVENANTS

15.1     The Executive acknowledges that during the course of his employment
         with the Company he will receive and have access to confidential
         information of the Company and its Associated Companies (including
         without limitation those matters specified in Clause 13.3 of this
         Agreement) and he will also receive and have access to detailed
         client/customer lists and information relating to the operations and
         business requirements of those clients/customers and accordingly he is
         willing to enter into the covenants described in this Clause 15 in
         order to provide the Company and its Associated Companies with what he
         considers to be reasonable protection for those interests.

                  involved to a material extent at any time during the period
                  of 12 (twelve) months ending on the Restriction Date and for
                  the purposes of this Clause 15 the term "Business" shall mean

                  damage the interests of the Company or any Associated Company
                  if he became employed in any business concern in competition
                  with any Restricted Business and with whom the Executive
                  worked closely or about whom the Executive obtained material

         or any Associated Company the business or custom of a Restricted

         engaged in or concerned in any capacity in any business concern which
         is or might reasonably be expected to be in competition with any
         Restricted Business. This Clause shall not restrain the Executive from
         being engaged or concerned in any business concern in so far as the
         Executive's duties or work shall relate solely:

         (a)      to geographical areas where the business concern is not in
                  competition with the Restricted Business; or

         or indirectly.

                                      14

15.8     The Executive hereby agrees that he will at the request and expense of
         the Company enter into a direct agreement or undertaking with any
         Associated Company whereby he will accept restrictions and provisions
         corresponding to the restrictions and provisions in this Clause 15 (or
         such of them as may be appropriate in the circumstances) in relation
         to such activities and such area and for such a period not exceeding
         12 (twelve) months as such Associated Company may reasonably require
         for the protection of its legitimate business interests.

15.9     It is agreed between the parties that whilst the restrictions set out
         in this Clause 15 are considered fair and reasonable for the
         protection of the Company's business and trade secrets, if it should
         be found that any of the restrictions be void as going beyond what is
         fair and reasonable in all the circumstances and if by deleting part
         of the wording or substituting a shorter period of time or different
         geographical limit or a more restricted range of activities for any of
         the period of time, geographical limits or ranges or activities set
         out in this Clause 15 it would not be void then there shall be
         substituted such next less extensive period and/or limit and/or
         activity or such deletions shall be made as shall render this Clause
         15 valid and enforceable.

16.1     For the purposes of this Clause 16:

         (a)      "RELEVANT EVENT" means either:

                           employment (other than for cause in accordance with
                           Clause 14 of this Agreement); or

                  (ii)     the Executive's resignation where such resignation
                           is as a consequence of a repudiatory breach of
                           contract by the Company and amounts to a
                           constructive dismissal,

                  within the period of 12 (twelve) months following the date of

16.2     If a Relevant Event occurs the Company shall pay to the Executive
         within 14 (fourteen) days of that Relevant Event a sum equal to the
         aggregate of:

         (a)      the value of his then current rate of basic salary for the
                  period of 1 (one) year; and

         (b)      an amount in lieu of annual bonus to be decided at the
                  absolute discretion of the Remuneration Committee up to the
                  maximum bonus, based on 100%

<PAGE>

                  year in which his employment terminates; and

         (c)      an amount in lieu of the Company's contributions to the
                  Executive's pension scheme under Clause 6 of this Agreement
                  for 1 (one) year; and

         Executive's employment under the provisions of any pension scheme of
         the Company, any payment by the Company pursuant to this Clause 16
         shall be made in full and final settlement of all and any claims
         arising from or in connection with the Executive's employment or its
         termination or his office as Group Research and Development Director
         or its loss in each case in respect of the Company or any Associated
         Companies.

16.4     All payments to be made pursuant to this Clause 16 shall be paid less
         any necessary withholdings.

16.5     The Executive hereby agrees that he shall not, following a payment
         under this Clause 16, bring any claim before any court or employment
         tribunal relating to unfair dismissal.

16.6     This Clause shall not apply where in connection with a scheme of
         reconstruction or amalgamation or reorganisation of the Company and
         one or more of its Associated Companies the Executive refuses an offer
         of employment on terms identical in all material respects to those
         hereunder by the company which following such reconstruction or
         reorganisation replaces the Company or the relevant Associated
         Companies.
