referred to the board of directors of each such Party. Each board shall nominate
one of its  members to confer  with a member  nominated  by the other  Party and
present to each board a recommended  solution.  If within thirty (30) days after

12.4  Effect of  Headings.  The  headings  to articles  and  paragraphs  of this
Agreement  are to  facilitate  reference  only,  do not  form  a  part  of  this
Agreement, and shall not in any way affect the interpretation hereof.

12.5 Entire  Agreement.  This Agreement,  with Related  Agreements and exhibits,
constitutes  the entire  agreement  of the Parties  with  respect to the subject
matter hereof and  supercedes  and cancels any and all prior  understandings  or
agreements, verbal or otherwise, in relation hereto, which may exist between the
Parties.  No amendment or change hereof or addition hereto shall be effective or
binding on either of the Parties  unless  reduced to writing and executed by the
respective duly authorized representatives of the Parties.

12.6  Waivers.  No term or condition  shall be deemed waived by any Party unless
the  waiver has been  reduced to  writing,  and signed by the  Parties  and such
waiver shall not  constitute or be deemed a waiver of any other right  hereunder
or against any other  failure to perform or breach  hereof by such other  Party,
whether of a similar or dissimilar nature hereto.

12.7. Representations and Warranties. All representations and warranties made by
either Party, whether by Party's officers,  employees,  agents,  representatives
and consultants,  whether acting or not in their authorized capacity but so long
as relied upon by the other Party relating to a material  fact,  shall be deemed
to be an essential condition of this Agreement,  the misstatement of which shall
give  cause to the  non-defaulting  Party to  rescind  this  Agreement  with the
resulting legal consequences.


                            Article 13. Miscellaneous

13.1 No Agency.  The Parties and JVC shall act in all matters pertaining to this
Agreement  as  independent   contractors  and  nothing  contained  herein  shall
constitute any Party or JVC the partner,  agent or legal  representative  of any
other Party or JVC.

13.2 Force Majeure.  Not withstanding any other provisions of this Agreement,  a
Party  shall  not be liable to the  other  Party  for any loss,  injury,  delay,
damages or other casualty suffered or incurred by

the latter due to strikes, riots, storms, fires,  explosions,  acts of God, war,
action of any  governmental or any other cause beyond the reasonable  control of
the Party, and any failure or delay by either Party in performance of any of its
obligations  under this  Agreement  due to one or more of the  foregoing  causes
shall not be a breach of this  Agreement.  However,  each Party  shall  promptly
notify the other Party of the  occurrence  of such force majeure  condition.  If
such  condition  continues  for longer than three (3) months,  the Parties shall
mutually  consult about the appropriate  modification  of this  Agreement.  This
provision  shall not exempt any Party from its duty to perform  the  obligations
under this  Agreement as soon as  practicable  after a force  majeure  condition
ceases to exist.

13.3  Severability.  In the event any term or provision of this Agreement  shall
for any  reason be  invalid,  illegal  or  unenforceable  in any  respect,  such
invalidity,  illegality or unenforceability  shall not affect any other terms or
provisions  hereof,  and in such event,  this Agreement shall be interpreted and
construed as if such term or provision, to the extent, that shall have been held
invalid, illegal or unenforceable, had never been contained herein.

Agreement shall be made in the English language and shall be sufficiently  given
