2 Subject Matter of the EULA

2.1 The subject matter of this EULA is the perpetual gratuitous grant of the License for the Licensed Software from its version v1.1.0. For the avoidance of doubt, vi:sit may in its sole discretion decide to release a different end user license agreement for any newer version(s) the Twizzar. In this case, such newer version(s) of Twizzar will not be subject to the present EULA but solely to the then applicable different end user license agreement. Notwithstanding the foregoing, this EULA remains in force and effect for the Licensed Software (i.e. from version v1.1.0 to the predecessor version of the version that is subject to the different end user license agreement).

2.2 The Licensed Software is a test framework for .NET that helps software developers write clear and maintainable unit tests. For the avoidance of doubt, the Licensed Software is a software tool to create unit tests, but is neither made nor designated for finding errors in the code of the software that shall be tested on the basis of the unit tests created with the Licensed Software. In addition, Licensee is aware that the Licensed Software is a solution based on Microsoft Visual Studio on Windows and can therefore only be Used as an add-on for Microsoft Visual Studio on Windows as long as Licensee uses the required standard software Microsoft Visual Studio (system requirements are specified in the Documentation). Licensee knows that it is not possible to Use the Licensed Software individually or together with or as an add-on to any other integrated development environment (IDE). No special infrastructure is required for the execution of unit tests developed with the Licensed Software. However, the component Twizzar-Library, for which Licensee can obtain a gratuitous license on the basis of a separate license agreement, must be referenced.

2.3 The provisions of this EULA govern exclusively. The Annex Basic-Plan forms an integral part of this EULA. Standard terms and conditions of Licensee do not apply, even if vi:sit has not expressly rejected the application of such terms and conditions.

2.4 Other work such as advice in selecting software, installation, implementation, modification, parametrization, customization, software maintenance, support, etc. or familiarization and training are not covered by this EULA. Such services, if offered by vi:sit at all, are subject to other contractual terms and conditions which are independent of this EULA.

Licensee shall, however, request vi:sit for, and give vi:sit an opportunity to provide within a reasonable time, the necessary information and documents for establishing interoperability before Licensee carries out any disassembly, de-compilation, reverse engineering or the like in accordance with Art. 21 of the Swiss Copyright Act (URG). Licensee may exercise its rights under Art. 21 of the Swiss Copyright Act (URG) only if vi:sit fails to comply with the aforesaid request. However, information obtained by way of disassembly, de-compilation, reverse engineering or the like must not be used or passed on to third parties for any other purpose than the development, maintenance and use of the other independently created interoperable computer program and must not be used to develop, produce or market a computer program substantially similar in its expression or for any other acts which infringe copyrights.
