          will have, prior to commencement of the Project, valid and sufficient
          arrangements and agreements with its respective employees and/or
          nonemployee consultants, such that the ownership of any and all
          inventions pertaining to any Joint PLC Products made by an employee
          and/or consultant vests in the Party hereto employing said employee
          and/or consultant, subject to the provisions of the applicable law
          governing ownership of such inventions.

     3.2  Each of the Parties agrees to reasonably enforce its respective
          intellectual property rights against infringement of same by third

          Party has the right to exploit and grant licenses in respect to such
          inventions, copyrightable material or proprietary information and any

          the other Party. In the event of a joint invention, the Parties shall
          mutually agree which Party shall have the responsibility for preparing
          and filing any patent application(s) on the invention in the United
          States and foreign countries; and the Parties agree that each will
          bear one-half of the actual out-of-pocket expenses associated with

          patent protection for any joint invention in any particular country or
          not to share equally in the expenses thereof with the other Party,

          apply for and maintain such patent protection in such country at its
          own expense (the non-electing Party undertaking to execute all such
          documents as may be necessary) and shall have full control over the
          prosecution and maintenance thereof, whereupon the non-electing

                                        2
<PAGE>

          Party shall assign its patent rights to the electing Party. An
          irrevocable royalty-free, non-exclusive, personal license to said
          PATENT rights shall then be granted by the electing Party to the
          non-electing Party. Should neither Party elect to file application for
          letters patent or take other necessary legal steps to protect such
          invention, the invention shall remain jointly owned.


4    INDEPENDENT DEVELOPMENT

     Nothing in the Agreement shall prevent either Party from continuing its
     independent development, manufacture and sale of its own technologies,
     including technology and products that are the subject matter of this
     Agreement nor require the same to become subject thereto, provided, that
     nothing herein shall be construed as a grant by either Party to the other
     Party of any rights in or licenses to the such Party's own technology in
     connection with such independent research and development efforts.

     if the party exercising such earlier right has a reasonable business basis
     for such termination. After the expiration of the initial term, either
     party may terminate this Agreement for any reason, with or without cause,
