user (the ”Licensee”), either an individual or an entity, and Dr. Peter Güntert (the ”Licensor”). The program package
CYANA 2.1 (copyright (c) 2002-2005 by Peter Güntert) 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 theLicensor provides the Licensee with updates of the Software, these will become part of the Software and will be controlled

5. The Licensee agrees that any reports or publications of results obtained with the Software will acknowledge its use by
the literature citation: Güntert, P., Mumenthaler, C. and Wüthrich, 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 orpublications of results obtained with the automated NOESY assignment module of the Software will acknowledge its useby the literature citation: Herrmann, T., Güntert, P. and Wüthrich, K. (2002). Protein NMR structure determination withautomated NOE assignment using the new software CANDID and the torsion angle dynamics algorithm DYANA. J. Mol.
Biol. 319, 209-227.
6. The Licensee agrees to pay to L. A. Systems, Inc. (the “Distributor”) the license fee specified by the Distributor. TheDistributor will deliver the Software upon receipt of a completed and duly signed original of this license agreement and of
the license fee.
