under such or other policies of insurance, they hereby waive claims of
subrogation against the other, if allowable by insurance carrier without voiding
coverage.

     Licensee's failure to provide and keep in force the aforementioned
insurance policies will be regarded as a default hereunder, entitling Inventor

arising out of or in connection with this Agreement shall be settled exclusively
and finally by arbitration conducted in accordance with the laws governing
arbitration by agreement. All limitations of liability set forth in this
Agreement, including but not limited to the limitations set forth in Article 5
hereof, shall be binding and given full force and effect in any such
arbitration. The arbitration shall be conducted by three (3) neutral arbitrators
who are selected by agreement of the parties from the list of qualified
arbitrators in the community. The arbitrators shall be selected within a period
of thirty (30) days after the date either party hereto receives from the other a
written demand for arbitration. Should the parties fail to agree on the choice
of arbitrators within such thirty (30) day period, the arbitrators shall be

                                       13

appointed by a judge of a court of competent jurisdiction. Judgment may be
entered upon any award rendered by the majority of the arbitrators in any court
of competent jurisdiction, or application may be made to any such court for a
judicial acceptance of the award and an order of enforcement, as the case may
be. Notwithstanding the agreement of the parties hereunder to submit disputes to
binding arbitration, Inventors shall not be required to resort to arbitration in
the event of a breach by Licensee of the terms in Article 7 hereof, but shall be
entitled to resort to the applicable court for any equitable relief available
for the redress of the breach thereof, including, but not limited to, injunctive
and interlocutory relief.

     In the event suit is brought or arbitration initiated for the recovery of
any sums due under this Agreement or for the breach of any covenant or condition
of this Agreement or for a declaration of rights under this Agreement, the
prevailing party shall be entitled to reasonable attorneys fees and all costs
incurred in connection therewith.

10.3 Independent Contractors

     Licensee acknowledges that it is not, and shall not hold itself out as, a
joint venturer, franchisee, partner, employee, servant, representative or agent
of Inventors. It is expressly agreed that the parties hereto are acting
hereunder as independent contractors, and under no circumstances shall any of
the employees of one party be deemed the employees of any other party for any
purpose. This Agreement shall not be construed as authority for any party to act
for another party in any agency or other capacity, or to make commitments of any
kind for the account of or on behalf of another party except to the extent and
for the purposes expressly provided for herein.

10.4 Non-Solicitation

     Unless otherwise mutually agreed to by the parties in writing, each party
agrees not to hire or to solicit the employment of any personnel of the other
party.

10.5 Notices

     Any notice required to be given hereunder shall be deemed given if in
writing and personally delivered or actually deposited in the United States mail
in registered or certified form, return receipt requested, postage pre-paid, and
addressed to the notified party at the address set forth above or as changed by
written notice.

10.6 Assignment

     This Agreement and the rights granted hereunder may not be assigned by
either party without the prior written consent of the other, except that
Inventors may assign this Agreement without the written consent of Licensee to a
parent company, subsidiary, affiliate or a purchaser of all or substantially all
of Inventors' rights in the Products.

10.7 Severability

     If any provision of this Agreement is determined by a court of competent
jurisdiction to be invalid or unenforceable, such determination shall not affect
the validity or enforceability of any other part or provision of this Agreement.

10.8 Waiver

     No waiver by any party of any breach of any provision hereof shall
constitute a waiver of any other breach of that or any other provision hereof.

10.9 Entire Agreement

     This Agreement, including the Schedules attached hereto, constitutes the
entire agreement between the parties with respect to the subject matter hereof
and supersedes all previous proposals, both oral and written, negotiations,
representations, commitments, writings and all other communications between the
parties. This Agreement may not be released, discharged, changed or modified
except by an instrument in writing signed by a duly authorized representative of
each of the parties.

     IN WITNESS WHEREOF, the parties hereto have executed this Agreement by a
duly authorized representative as of the date herein set forth.
