1.3  Open Source Software.  The Software may contain code, commonly referred to as open source software, which is distributed under any of the many known variations of open source licence terms, including terms which allow the free distribution and modification of the relevant software's source code and/or which require all distributors to make such source code freely available upon request, including any contributions or modifications made by such distributor (collectively, 'Open Source Software'). To the extent that the Software contains any Open Source Software, that element only is licensed to you pursuant to the relevant licence terms of the applicable third party licensor ('Open Source Licence Terms') and not pursuant to this Licence, and you accept and agree to be bound by such terms. A copy of the Open Source Licence Terms will be made available upon request.

2.  Confidentiality Obligations.  You acknowledge that the Software contains confidential, proprietary and trade secret information belonging to SDRplay and you agree to hold such information, and any other confidential or proprietary information of SDRplay (collectively, "Confidential Information") in strict confidence and agree not to disclose any Confidential Information to any third party.

You acknowledge that, except as expressly set out in this Licence, nothing in this Licence will give you rights in respect of any intellectual property rights owned by SDRplay or its licensors. All intellectual property rights and other rights of SDRplay and its licensors which are not expressly granted to you by this Licence are reserved. 

4.  Limited Warranty.  SDRplay warrants that the Software will, under normal operating conditions, operate substantially in accordance with SDRplay's published specification for the Software.

7.  General.    You may not transfer or assign any or all of your rights and/or obligations under this Licence. All notices given by you to SDRplay must be given in writing to SDRplay's registered office address. If SDRplay fails to enforce any of our rights, that does not result in a waiver of that right. If any provision of these terms and conditions is found to be unenforceable, all other provisions shall remain unaffected. The terms of this Licence may not be varied except with SDRplay's express written consent. The terms of this Licence represent the entire agreement between you and SDRplay in relation to the subject matter of this Licence. The terms of this Licence shall be governed by English law and you agree that any claim you may have against SDRplay arising under or in connection with this Licence and/or the Software may only be dealt with by the English courts, provided that, if you are a consumer: (a) and you live in a part of the United Kingdom other than England, the applicable law of that part of the United Kingdom will govern and any claim may be brought by you before the courts there; or (b) you live in another member state of the European Union, any claim may be brought by you before the courts there.
