3.   Technology License Fee.
     -----------------------

     3.1  Equity in  Licensee.  In  consideration  for the rights  and  licenses
          granted  hereunder  subject to approval by the board of  directors  of
          Licensee,  Licensee  shall  deliver to  Licensor  shares of its common
          stock as set forth in Schedule B.

     3.2  Royalty.  For the  life  of  this  Agreement,  Licensee  shall  pay to
          Licensor a royalty in the  amount of $75.00 for every  Device  sold by
          Licensee  which,  absent the right and license  granted by Licensor to
          Licensee under Section 2.1, would infringe Licensor's rights under the
          Licensed  Subject  Matter.  In the event  that  Licensee  places  such
          Devices  with end users at no cost,  Licensee  shall pay  Licensor the
          same royalty as set forth herein.

     3.3  Adjustment of Royalties.  A determination  of invalidity of any claims
          of the patents that constitute the  Intellectual  Property Rights does
          not relieve Licensee from payment of royalties, nor provide any ground
          for refund of  royalties  already  paid for the practice of any patent
          claims  that  have  not been  adjudicated  to be  invalid,  or for the
          licensed use of  Technology  Rights  relating to the Licensed  Subject
          Matter.  In the event of  adjudication  of  invalidity  of any  patent
          claims,  Licensee  shall be entitled to an  adjusted  royalty  that is
          reasonably related to the value of the Licensed Subject matter,  which
          shall be negotiated by the parties.

     3.4  Document   Delivery.    Licensor   shall   make   available   existing
          documentation  relating to design and  manufacturing  of the  Devices.

                 limitation: documents of materials, suppliers, all phases of
                 manufacturing,  and all manufacturing quality assurance test
                 procedures related to Licensor's Device.



     3.5  Records,  Reports  and Payment of  Royalties.  During the term of this
          Agreement  and for five (5)  years  thereafter,  Licensee  shall  keep
          complete and accurate records of the sale of the Devices which, absent
          the right and license  granted by Licensor to Licensee  under  Section
          2.1, would infringe Licensor rights under the Licensed Subject Matter,
          in sufficient detail to enable the royalties payable to Licensor under
          Section 3.2 of this Agreement to be determined. Within sixty (60) days
          after  the end of each  fiscal  quarter,  which end on the last day of
          January,  April,  July and  October,  during  which  units  using  the
          technology  licensed  under this  Agreement  have been sold,  Licensee
          shall furnish to Licensor a written report setting forth the number of
          such Devices sold in such  just-ended  fiscal  quarter,  together with
          royalties payable to Licensor pursuant to Section 3.2.

     3.6  Audit Rights.  Licensee shall permit Licensor,  or  representatives of
          Licensor  which are reasonably  acceptable to Licensee,  at Licensor's
          expense,  to  periodically  examine  Licensee's  books,  ledgers,  and
          records  during  regular  business  hours for the sole purpose of, and
          only to the extent necessary,  to verify reports furnished to Licensor
          pursuant to Section 3.5; provided that Licensor delivers to Licensee a
          written  notice of Licensor's  intention to conduct an inspection  not
          less than ten (10)  business  days  before the  intended  date of such
          inspection; and provided further that only one (1) such inspection may
          be conducted  during any calendar six (6) month  period.  In the event
          that amounts due Licensor are  determined to have been underpaid by an
          amount  greater  than ten percent  (10%) of the amount  actually  due,
          Licensee shall pay the cost of such  examination.  Any royalty payment
          not paid on or before the date  corresponding  to forty five (45) days

                                        3

          permitted under applicable law. Notwithstanding the above, each report
          delivered by Licensee to Licensor  pursuant to Section  3.5,  shall be
          deemed  correct  and  accurate,  and  Licensor  shall have no right to
          inspection  records  relating  thereto,  or  otherwise  challenge  the
          accuracy of either such report or the records relating thereto,  after
          the  third  anniversary  of the date of  delivery  of such  report  to
          Licensor.
