    of which is manufacturing, distributing, marketing and/or selling
    pharmaceutical products the rights to which are owned by or licensed to

    consolidated revenues or five percent (5%) of consolidated expenses of such
    company; provided further that Vendor shall have no direct involvement in
    such Related Activities as a director, officer, employee, consultant or
    otherwise; provided further, it is agreed that Related Activities are
    intended to be limited to activities which are incidental to the operations

    of drug development, marketing, sales services, or health benefit analysis
    of the products or potential products of third parties.

        (ii)    the provision of executive search consulting services so long

        as such services are not provided to an entity engaged in Related
        Activities; and

        (iii)   the provision of financial consulting services so long as such
        services are not provided to an entity engaged in Related Activities.

2.3 Holding of Shares or Securities.  Section 2.2 shall not prohibit the
    holding (directly or through nominees or otherwise) of shares or other      
    securities of another company which are listed or traded on any recognized
    stock exchange being a holding (which phrase shall include any interest in
    any such holding) entitling the holder to no more than two and one half
    percent (2.5%) of the voting power of such body corporate.

2.4 Nondisclosure.  The Vendor shall not either before or after the
    termination of his employment disclose to any person or persons any
    confidential information in relation to the affairs of the Purchaser or any 
    of its Affiliates or any client or customer thereof which he has become
    or may have become possessed whilst in the service of the Purchaser except
    in the proper course of his duties as an officer, director or employee of
    the Purchaser or as authorized by the Board or as ordered by a Court of
    competent jurisdiction or pursuant to other governmental process.

2.5 Geographical Restriction.  The restrictions set forth in Sections
    2.2(a) apply to the following geographical areas: the United Kingdom, the

2.6 Non-Competition Period.  As used in this Agreement "Non-Competition
    Period" means the eighteen (18) month period following the termination of
    Vendor's employment, (irrespective of the circumstances of such
    termination, except that the final six months of any garden leave period
    shall run concurrently with the first six months of the Non-Competition
    Period), except that for purposes of the restrictions set forth in Sections
    2.2(b) and 2.2(c) (regarding solicitation, etc.), "Non-Competition Period"
    shall mean the twenty-four (24) month period following the termination of
    Vendor's employment (irrespective of the circumstances of such termination).

2.7 Remedies.  Vendor acknowledges and agrees that Vendor's failure to
    abide by the provisions of this Agreement would cause irreparable harm to
    the Purchaser and/or its Affiliates for which legal remedies would be
    inadequate. Therefore, in addition to any legal or other relief to which
    the Purchaser and/or its Affiliates may be entitled by virtue of
    Vendor's failure to abide by these provisions: (i) the Purchaser may seek
    legal and equitable relief, including but not limited to preliminary and
    permanent injunctive relief, for Vendor's actual or threatened failure to
    abide by these provisions; (ii) Vendor will, upon final judicial
    determination that Vendor has breached the terms of this Agreement,
    indemnify the Purchaser and/or its Affiliates for all expenses (including
    legal fees) in seeking to enforce these provisions; and (iii) if, as a
    result of Vendor's failure to abide by the provisions, any commission or
    fee becomes payable to Vendor or to any person, corporation or other entity
    with which Vendor has become employed or otherwise associated, Vendor shall
    pay the Purchaser or cause the person, corporation or other entity with
    whom he has become employed or otherwise associated to pay the Purchaser an
    amount equal to such commission or fee.

2.8 Other Agreements.  Nothing in this Agreement shall terminate, revoke
    or diminish Vendor's obligations or the Purchaser's and/or its Affiliates'
    rights and remedies under law or under Vendor's existing service agreement  
    and the Share Exchange Agreement relating to trade secrets, confidential
    information, non-competition and intellectual property.
