CYANA 2.2 Software License


The CYANA 2.2 Software License is a legal agreement, governed by the
laws of Switzerland, between an end user (the "Licensee"), either an
individual or an entity, and Dr. Peter Guntert (the "Licensor"). The
program package CYANA 2.2 (copyright (c) 2002-2007 by Peter Guntert)
for NMR structure calculation, comprising all computer programs, 
source code, license keys, documentation, example data and other files
delivered to the Licensee, as well as any copies, modifications or
derivative works made by the Licensee, are hereinafter referred to
collectively as the "Software". A derivative work is any software that
contains one or several parts of the Software in original or modified
form. If the Licensor provides the Licensee with updates of the
Software, these will become part of the Software and will be controlled
by this license.


 1. The Licensor grants to the Licensee a non-exclusive,
    non-transferable, permanent license to install and use the
    Software on computer systems located at the site of the Licensee's
    organization. However, a violation of any of the clauses of this
    license agreement by the Licensee shall terminate automatically
    and with immediate effect the Licensee's right to install, use or
    store the Software in any form. Use of the Software is restricted
    to the Licensee and to direct collaborators who are members of the
    organization of the Licensee at the site of the Licensee and who
    accept the terms of this license. The Licensee shall neither use
    the Software to produce other software that duplicates
    functionality of the Software nor translate source code of the
    Software into another programming language.

 2. The Licensor retains at all times ownership of the Software
    delivered to the Licensee. Any modifications or derivative works
    based on the Software are considered part of the Software, and
    ownership thereof is retained by the Licensor. All parts of the
    Software must carry the copyright notice, will be controlled by
    this license, and will be promptly destroyed by the Licensee upon
    termination of this license.

 3. The Licensee shall not use the Software for any purpose (research
    or otherwise) that is supported by a "for profit" organization
    without prior written authorization from the Licensor.
    [This Article does not apply to Licensees who have obtained
     a Commercial License.]

 4. The Licensee shall not disclose in any form the Software or any
    modifications or derivative works based on the Software to third
    parties without prior written authorization from the Licensor.

 5. The Licensee agrees that the Software has been developed in
    connection with academic research projects and is provided "as
    is". The Licensor disclaims all warranties with regard to the
    Software or any of its results, including any implied warranties
    of merchantability or fitness for a particular purpose. In no
    event shall the Licensor be liable for any damages, however
    caused, including, without limitation, any damages arising out of
    the use of the Software, loss of use of the Software, or damage of
    any sort to the Licensee.

 6. The Licensee agrees that any reports or publications of results
    obtained with the Software will acknowledge its use by the
    literature citation: Guntert, P., Mumenthaler, C. and Wuthrich, K.
    (1997). Torsion angle dynamics for NMR structure calculation with
    the new program DYANA. J. Mol. Biol. 273, 283-298. In addition,
    the Licensee agrees that any reports or publications of results
    obtained with automated NOESY assignment using the Software will 
    acknowledge its use by the literature citation: Herrmann, T., 
    Guntert, P. and Wuthrich, K. (2002). Protein NMR structure 
    determination with automated NOE assignment using the new software 
    CANDID and the torsion angle dynamics algorithm DYANA. J. Mol. Biol.
    319, 209-227.

 7. The Licensee agrees to pay to the Licensor the license fee
    specified by the Licensor. The Licensor will deliver the Software
    upon receipt of a duly signed original of this license agreement
    and of the license fee.
