             explanations and supply all information in his possession as the

             (pound)36,000 per annum or such other rate as the parties may

             Executive must still be in service and not under notice of
             termination on the date appointed for payment of the bonus. The
             amount of the bonus (if any) shall be in the absolute discretion of
             the Board and the Board shall be entitled to terminate any bonus
             put in place at any time upon one month's written notice to the
             Executive.

             scheme.

      information and evidence of the same including, without limitation,
      original receipts as the Company shall reasonably require and provided

      or in excess of (pound)6,000 in aggregate without the prior written
      approval of the Board.

7.    HOLIDAYS

      7.1    The Executive shall be entitled to 25 working days' holiday in each
             calendar year at times convenient to the Board in addition to bank

             salary as set out in clause 4.1 above in respect of all holidays
             taken. The entitlement to holiday and, on termination of the
             Employment, holiday pay in lieu of holiday, shall accrue pro rata
             throughout each year of the Employment.

      7.2    The Executive may not carry forward any unused holiday entitlement
             to any subsequent year without the consent of the Board. Any unused

             appropriate, pay the Executive in lieu of holiday accrued but not
             taken by the date of termination of the Employment (except where
             the Employment is terminated for gross misconduct, in which case no
             payment will be made) or deduct from the Executive's final salary
             payment or (in the event that this is insufficient) require the
             Executive to pay to the Company, an amount representing salary paid
             during holiday taken but not accrued by the date of termination of
             the Employment.

             the Executive to be examined by a medical adviser nominated by the

             first six months of absence, the Executive shall be entitled to

             subsequent six months of absence, the Executive shall be entitled
             to half basic salary. All payments made by the Company shall be

             or omission of a third party the Executive must, at the Company's
             request, include in any claim for damages against such third party
             a claim in respect of monies paid by the Company under this clause
             8 and must refund to the Company any damages recovered under that
             head.

             any person any information of a private, confidential or secret
             nature concerning the business, products, processes or affairs of
             the Company or any Associated Company or of any person having
             dealings with the Company or any Associated Company and which comes

             documents, papers and records which may have been prepared by him
             or have come into his possession in the course of the Employment

                     any Associated Company or not) or serious or persistent
                     misconduct or any other conduct which, in the opinion of
                     the Board, tends to bring the Executive or the Company or

             10.1.2  without reasonable cause willfully neglect or refuse to

14.   INTELLECTUAL PROPERTY

      14.1   The Executive will promptly disclose to the Company any invention,
             development, discovery, improvement, new software or source code or
             design made by him whether alone or with others during the
             performance of his duties as an employee and whether or not the
             same is capable of protection as intellectual property by patent,
             copyright, design right, as a trade mark or by other means and he
             shall not use, disclose to any person or exploit the same without
             the express prior written consent of the Company.

      14.2   Subject to any rights granted to the Executive by the Patents Act
             1977 which cannot be excluded by agreement, any invention,
             discovery, design, development, or improvement whether or not
             capable of protection by patent registered design or otherwise and
             any copyright in any document, letter, software or other work
             protectable by copyright suggested written, created, designed,
             invented, conceived or acquired by the Executive during the course
             of his employment ("the Intellectual Property") shall belong
             absolutely to the Company and to the extent that some or all of the
             rights pertaining to the Intellectual Property do not vest
             automatically in the Company the Executive hereby as beneficial
             owner assigns to the Company all his rights whatsoever in the
             Intellectual Property. The Executive will provide the Company with
             full details and information with regard thereto and will at the
             request and expense of the Company apply to join with the Company
             in applying for registration of any of the Intellectual Property in
             the United Kingdom and/or in any other part of the world as
             specified by the Company.

      14.3   The Executive will at the Company's request and expense do all such
             things and sign all documents or instruments reasonably necessary
             in the opinion of the Company to obtain, defend and enforce its
             rights in the Intellectual Property and in the meantime will hold
             all interest therein in trust for the Company. The Executive hereby
             irrevocably appoints the Company to be his attorney in his name and
             on his behalf to execute any such document or instrument and
             generally to use his name for the purpose of giving to the Company
             (or its nominee) the full benefit of the provisions of this Clause
             15 and in favour of any third party a certificate in writing signed
             by any Director or Secretary of the Company that any instrument or
             act falls within the authority hereby conferred shall be conclusive
             evidence that such is the case.

      14.4   The Executive hereby waives all moral rights in any copyright works
             originated, conceived, written or made by him (either alone or with
             others) and agrees not to claim that any treatment, exploitation or
             use of the said works infringe such moral rights (including but not
             limited to the right to be identified, the right to object to
             derogatory treatment and the right against false attribution).

      14.5   Each of the obligations under this Clause 14 is enforceable
             independently of each of the others and its validity will not be
             affected if any of the others is unenforceable to any extent.

      14.6   Rights and obligations under this Clause 14 shall continue in force
             after termination of the Employment in respect of Intellectual
             Property and shall be binding on the Executive's personal
             representatives.

15.   DATA PROTECTION

      15.1   The Executive agrees that the Company may use information about him
             which he may provide to the Company or which the Company may
             acquire during the course of this Agreement provided that such use
             is in accordance with the Data Protection Act 1998.

      15.2   The Executive hereby consents to the processing of any data
             relating to him, in particular, to the processing of any "sensitive
             personal data" (as defined in the Data Protection Act 1998)
             relating to him (including, for example, information relating to
             his health or racial or ethnic origin).

      15.3   The Executive authorises the transfer of any personal data held
             pursuant to the terms and conditions of his employment by the
             Company to any third party located outside the United Kingdom.

16.   REDUNDANCY

      16.1   If, during the first 12 months of this Agreement, the Company is to
             be wound up or is to cease to trade in the United Kingdom for any
             reason, the Company reserves the option to terminate the Employment
             by paying in lieu of notice three months basic salary. In addition,
             the Company shall pay the Executive either (a) a further three
             months basic salary or (b) the remaining unpaid portion of the
             Executive's basis salary for the first 12 months whichever sum is
             the greater. The payment made under this clause 16.1 shall be
             subject to deductions for income tax and national insurance
             contributions as appropriate.

      16.2   If the Employment is not renewed on the expiry of the fixed period
             or any renewal or extension of it, the Executive agrees that he
             shall have no entitlement to statutory redundancy pay.

17.   OTHER AGREEMENTS

      17.1   This Agreement shall, from the Commencement Date, operate in
             substitution for any terms of service previously in force (whether
             written or oral) between the Company and/or any Associated Company
             and the Executive and the Executive acknowledges and warrants that
             there are no agreements or arrangements whether written, oral or
             implied between the Company or any Associated Company and the
             Executive relating to the employment of the Executive other than
             those expressly set out or referred to in this Agreement and that
             he is not entering into this Agreement in reliance on any
             representation not expressly set out herein.

20.   STATUTORY PARTICULARS

      20.1   The following particulars are given in compliance with the
             Employment Rights Act 1996 so far as not already taken into account
             elsewhere to this Agreement:-

             20.1.1  There are no specific disciplinary rules applicable to the
                     Employment but the Executive is expected at all times to
                     conduct himself in a manner consistent with his senior
                     status.

             20.1.2  In the event of the Executive either being dissatisfied
                     with any disciplinary decision or wishing to seek to
                     address any grievance relating to the Employment, he should
                     first apply to the chairman. If the matter is not resolved
                     within seven days, the Executive may appeal to the Board
                     which will afford to the Executive the opportunity of a
                     full and fair hearing at a meeting of the Board or a duly
                     appointed committee thereof whose decision shall be final
                     and binding.

             20.1.3  A Contracting Out Certificate under the Pension Schemes Act
                     1993 has not been issued in respect of the Employment.

             20.1.4  There are no collective agreements which affect the terms
                     and conditions of Employment.

             20.1.5  There is no employment with a previous employer which
                     counts as part of the Executive's continuous period of
                     employment for the purposes of the Employment Rights Act
                     1996.


IN WITNESS whereof the parties have executed this Agreement on the date first
above written.
