Agreement or shortly thereafter. The Client agrees that the Consultant may sell
the Shares at such times and in such manner as may be determined in the sole
discretion of the Consultant. Client understands that any sales of the Shares by
Consultant may have the effect of decreasing the trading price of the Client's
stock, particularly if Client's stock is thinly traded. The Consultant will use
reasonable efforts to make such sales at such times and in such a manner so as
to minimize any adverse effect to the Client from sales of the Shares. Under no
circumstances will the Client place stop transfer instructions ("Stop Transfer
Instructions") with its transfer agent with respect to the Shares. In the event

authorization of the Client, any Confidential Information to any person, except
authorized representatives of the Consultant or its affiliates, for any reason
or purpose whatsoever. In this regard, the Client agrees that such authorization
or consent to disclose may be conditioned upon the disclosure being made
pursuant to a secrecy agreement, protective order, provision of statute, rule,
regulation or procedure under which the confidentiality of the information is
maintained in the hands of the person to whom the information is to be disclosed
or in compliance with the terms of a judicial order or administrative process.
Any information which has been disclosed to the public by the Client or upon the
specific written authorization of the client shall not be considered
Confidential Information.


                           VII. NATURE OF RELATIONSHIP
