(d)  Termination for Just Cause: The Employee's employment may be terminated for
     "just cause", examples of which are defined as follows:

     The Company may unilaterally terminate the Employee's employment hereunder
     "for just cause" at any time during the term of this agreement. Termination
     of the Employee's employment by the Company shall constitute a termination
     "for just cause" if such termination is for one or more of the following
     causes: (i) willful misconduct of the Employee in connection with the
     performance of his assigned duties; (ii) the Employee's willful, material
     breach of this Agreement or the willful breach of duties, which results in
     damage or injury to the Company or adversely affects the business
     activities, operations, reputation, goodwill or image of the Company or its
     customers, (iii) the conviction of the Employee of a felony or proven
     commission (i.e., a substantiated allegation) of an act of fraud or
     embezzlement, either in connection with the performance of his obligations
     to the Company or which materially adversely affects the Employee's ability
     to perform such obligations, or which adversely affects the business
     activities, operations, reputation, goodwill or image of the Company; (iv)
     breach of fiduciary duty as an officer of the Company; (v) the willful
     commission by Employee of an act which induces any employee or customer of
     the Company to break a contract with the Company, other than at the request
     of the Company; or (vi) knowingly infringes or misappropriates any
     intellectual property of the Company, including without limitation any
     trade secrets of any third party.

     Any action or inaction or omission on the Employee's part shall be
     considered willful if taken, or omitted to be taken, as the case may be, by
     the Employee without a reasonable belief that the action or omission was in
     the best interest of the Company or that the act or omission was in good
     faith. After notice of termination for cause has been delivered to the
     Employee, the Employee shall be entitled to have the grounds for
     termination of employment reviewed by the Board of Directors, provided such
     entitlement to review shall not serve to extend the date upon which the
     termination of employment shall become effective. In making any
     determination under this Section, the Board of Directors shall act fairly
     and in utmost good faith and shall give the Employee an opportunity to
     appear and be heard with counsel at a meeting of the Board of Directors and
     present evidence on his behalf.

     In the event of any such termination for "cause," the Employee shall be
     entitled to receive upon termination to: (i) earned and unpaid salary,
     bonus and vacation through the termination date, (ii) benefits for the
     applicable period permitted by statute, provided Employee makes the
     appropriate voluntary contribution payments, and subject to applicable law
     and the requirements of the Company's health and insurance plans then in
     effect, (iii) vested options (to the extent then vested) and (iv) no other
     severance or other compensation benefits, other than payments which are
     required by law to be provided to all discharged employees.

(e)  Voluntary Termination. The Employee may voluntarily terminate his
     employment at any time by providing the Company with forty-five (45) days
     prior written notice of termination. In the event of any such voluntary
     termination by the Employee, the Employee shall be entitled to (i) accrued
     and unpaid salary, bonus, and vacation through
<PAGE>

     the termination date, (ii) benefits for the applicable period permitted by
     statute,

Mr. Paul Ayres

     provided Employee makes the appropriate voluntary contribution payments,
     and subject to applicable law and the requirements of the Company's health
     and insurance plans then in effect, (iii) vested options (to the extent
     then vested) and (iv) no other severance or other compensation benefits,
     other than payments which are required by law to be provided to all
     discharged employees.

(f)  At the Election of the Company for Reasons Other Than Just Cause.  The
     Company may, immediately and unilaterally, terminate the Employee's
     employment hereunder at any time during the term of this Agreement without
     "cause" by giving thirty (30) days' advance written notice to the Employee
     of the Company's election to terminate.  During such period, the Employee
     will be available on a full-time basis for the benefit of the Company to
     assist the Company in matters relating to the transition of a new,
     successor officer of the Company.  In the event the Company exercises its
     right to terminate the Employee under this section during the first year,
     the Company agrees to pay the Employee a severance or termination payment
     of twelve months' base salary at the then current base rate, payable in the
     same manner as such salary was payable during the term of the Employee's
     employment.  Such severance payment shall be payable on a monthly basis for
     the twelve (12) months following the Employee's termination and shall be
     subject to all applicable federal and state taxes, and this obligation
     shall survive termination of this Agreement.  In addition, the Employee
     shall be entitled to (i) accrued and unpaid salary, bonus, and vacation
     through the termination date, (ii) Health benefits for the applicable
     period permitted by statute, provided Employee makes the appropriate
     voluntary contribution payments, and subject to applicable law and the
     requirements of the Company's health and insurance plans then in effect,
     (iii) vested options, and (iv) 50% of the unvested stock provided in this
     agreement.

     In the event the Company exercises its right to terminate the Employee
     under this section after the first year of employment, the Company agrees
     to pay the Employee a severance or termination payment of six months' base
     salary at the then current base rate, payable in the same manner as such
     salary was payable during the term of the Employee's employment.

     Such severance payment shall be payable on a monthly basis for the six (6)
     months following the Employee's termination and shall be subject to all
     applicable statutory taxes, and this obligation shall survive termination
     of this Agreement. In addition, the Employee shall be entitled to (i)
     accrued and unpaid salary, bonus, and vacation through the termination
     date, (ii) benefits for the applicable period permitted by statute,
     provided Employee makes the appropriate voluntary contribution payments,
     and subject to applicable law and the requirements of the Company's health
     and insurance plans then in effect, (iii) vested options, and (iv) 50% of
     the unvested stock provided in this agreement.

     It shall be deemed to be a constructive termination "without cause" if: (i)
     the Employee's responsibilities are reduced or diluted in any material way;
     (ii) the Employee's annual salary or bonus arrangement is reduced in any
     material way; or (iii) the Employee is relocated to another Company office
     or facility to a location outside of a radius of 100 miles from the
     Company's current facility or without the Employee's written consent; or

    (iv) there occurs a determination by the Employee made in good faith that as
    a result of any material change in the scope of the business or other
    activities for which he is responsible, he has been rendered unable to carry
    out, has been hindered in the performance of, or has suffered a reduction
    in, in a material way, of any of the authorities, powers, functions,
    responsibilities or duties attached to the officer position held by
    employee, which situation is not remedied within 30 business days after
    written notice to Company from Employee of such determination.

g)  Change of Ownership: In the event that there is a change of ownership of
    more than 50% in a single or series of transactions, the option shares'
    restrictions will be lifted and the remaining unvested shares of this
    agreement will vest and become immediately exercisable;

h)  Governing Law: This Agreement shall be governed and construed in accordance
    with the laws of England.

i)  Insider Trading Policy: You agree to comply with the Company's Insider
    Trading Policy ("Policy") [attached], as the Policy may be amended or
