        -----                        -------
settlement shall be deemed to have failed as soon as one of the Parties notifies
the other Party or Parties in writing. If such an attempt has failed, all

States) shall be finally settled pursuant to the rules of arbitration of the ICC
by three arbitrators in accordance with said rules. Each opposing Party shall
nominate one arbitrator to be confirmed by the International Court of
Arbitration under the applicable rules. Both arbitrators should agree on the
third arbitrator within 30 days. Should the two arbitrators fail, within the
above time limit to reach agreement on the third arbitrator, he shall be
appointed by the International Court of Arbitration. Where there are multiple
parties, whether as claimant or as respondent, the arbitral tribunal shall be
constituted in accordance with Article 10 of the ICC rules. The site of
arbitration shall be Frankfurt am Main, Germany. Unless the Parties otherwise
agree, the procedural law of this place shall apply where the rules are silent.
The language to be used in the arbitration procedure shall be English. The
arbitration court should also decide on the liability of costs including the
reimbursement of reasonable attorney fees.

          SECTION 4.06.  Final Provisions. If a provision of this Agreement
should be without effect in whole or in part, the validity of the remaining
provisions of this Agreement shall remain unaffected thereby. The Trustor and
Trustee shall promptly agree upon a valid and legally enforceable provision that
comes as close as possible to the economic meaning and purpose of the (partly or
in whole) ineffective or unenforceable provision in order to replace such
provision.
