        content of the system.

(2) In case of doubt the Institute shall be asked for written consent.


Article 4  Obligations of the Licensee

(1) Sub-licenses must confer the identical legal position which is granted by

same prohibition as the Licensee.

refer to the present license terms as follows:

(3) The source code and each conversion resulting from its utilization must 
be provided with the name Oberon and designate as author the "Team of the 
Institute for Computer Systems of ETH Zuerich" at the beginning. Any further
developments, updates and applications must be marked "based on Oberon".

(4) Modifications by the Licensee are to be clearly identified.


Article 5  Consequences of Infringements

Each infringement of these license terms shall directly result in the loss of
the rights granted in Article 2. There shall be no right to distribute those
products which have been produced in violation of this contract.


Article 6  Information

(1) Upon request the Institute (e-mail: oberon@inf.ethz.ch) shall provide the
Licensee with information on modifications, updates and further developments
of the source code by the Institute.

Institute their applications, modifications, updates and further developments
of the source code as well as the thereby gained experiences and knowledge.


Article 7  Liability

(1) The Institute does not assume any liability for damage directly or 
indirectly caused by the application of the source code.

(2) If a third party takes legal action based on infringement of its 
protective rights by the Licensee's use of the source code, the contract
party sued must immediately notify the other contract party. The Licensee is
not entitled to conclude a settlement without the expressive and written 
consent of the Institute.


Article 8  Modifications

The Institute may modify these license terms. The valid version may be
downloaded or requested as mentioned in Article 4 sub-paragraph 2.

sub-paragraphs 2 - 4 shall remain effective even after the termination
of the license.
