                         II. CONFIDENTIAL INFORMATION

     Receiving Party shall not divulge or communicate to any person (other than
those whose province it is to know the same or with proper authority) any of the
trade secrets or other confidential information of BioLynx, BioLynx's
subsidiaries and/or affiliated persons or entities which may have been received
or obtained during the course of this Agreement. This restriction shall continue
to apply after the termination of this Agreement without limit in point of time
but shall cease to apply to information or knowledge which may come into the
public domain.

     For purposes of this Agreement, the term "Confidential Information" shall
include, without limitation, information (including product designs,
illustrations, prototypes, and software), records, know-how, technology,
business plans, policies, strategies and/or practices, trade secrets, written
documentation, electronic files, computer programs, illustrations, edited works,
and financial and/or operating data relating to BioLynx or BioLynx's existing or
potential Business policies or practices.

                         III.  FAILURE OF TRANSACTION

     All information and all copies of information (including all product

returned to BioLynx upon request, in the event negotiations for Project are
terminated. Receiving Party agrees not to retain any copy, summary or extract of
Information provided to it by BioLynx. Upon request of BioLynx, Receiving Party
shall provide a certification from an appropriate officer that the requirements
of this paragraph have been satisfied in full.

                           IV. MANDATORY DISCLOSURE

     In the event that Receiving Party or anyone to whom Receiving Party
transmits Information pursuant to this Agreement becomes compelled by law or by
any court or governmental agency to disclose any of the Information, Receiving
Party will provide BioLynx with prompt notice prior to the disclosure so that
BioLynx may seek a protective order or other appropriate remedy and/or waive
compliance with the provisions of this Agreement. In the event that such
protective order or other remedy is not obtained, or that BioLynx waives
compliance with the provisions of this Agreement, Receiving Party will furnish
only that portion of the Information which is believed to be legally required
and will exercise its best efforts to obtain assurance that confidential
treatment will be accorded the Information.

been made available by BioLynx, that discussion or negotiations are taking place
concerning a possible transaction involving either BioLynx or Receiving Party,
or any of the terms, conditions or other facts with respect to such possible
transaction.

                               VI. CHOICE OF LAW

     The laws of the State of Texas govern any interpretation of the provisions
of this Agreement without regard to Conflict of Law principles.

Agreement by Receiving Party, Receiving Party affiliates, agents representatives

inadequate to protect against breach of this Agreement, and Receiving Party
