furnished by Licensor, and to transfer by cable within the same period the
resultant royalties in Deutsche Mark for all Equipment distributed during the
period reported for into an account specified by Licensor stating in the
remittance the number of the Agreement together with the word "Royalties"; for
periods where no royalties have become payable "nil royalty statements" shall be

including this Article 12.1 - require the written form and signature by both
parties to become legally binding.

12.2 Should any provision of this Agreement be invalid this shall not invalidate
the whole of this Agreement. Any invalid condition shall much rather be replaced

closest to the economical intent of the original provision.

Republic of Germany excluding the conflict of law regulations. The stipulations
of international conventions regarding the international sale of goods shall not
be applicable.

from the question of its coming into effect as well as those that originate from
the Agreement after its termination, shall be settled in a final manner by a
Court of Arbitration to be convened at Zurich/Switzerland.

12.5 The Court of Arbitration shall consist of three arbitrators. Each party
shall appoint its arbitrator, and the third, who is to act as chairman, is to be
appointed jointly by the two first-mentioned arbitrators. If one party fails to
appoint its arbitrator within four weeks after receipt of the respective written
request of the other party, or if the two first-mentioned arbitrators cannot
come to an agreement on the third arbitrator within four weeks, the respective
arbitrator is to be appointed by the President of the International Chamber of
Commerce at Paris. The chairman of the Court of Arbitration shall be a fully
qualified jurist of Swiss nationality who is experienced in arbitration.

12.6 The Court of Arbitration shall act on the basis of the Rules of Arbitration
and Conciliation (Edition 1988) of the International Chamber of Commerce. The
Code of Civil Procedure of the Canton Bern shall supplement said Rules.

12.7 Claims for payments may be filed in any ordinary court in the option of
Licensor.

SCHEDULE 2

The Process

A method of anisotropic etching of structures preferably defined with an etching
mask, particularly laterally exactly defined recesses in silicon, by means of a
plasma, characterised in that the anisotropic etching process is performed
separately in separate respectively alternating sequential etching and
polymersation steps which are controlled independently of one another and that a
polymer applied during the polymerisation step to the lateral definition of the
structures defined by the etching mask is partially re-stripped during the
subsequent etching step.
