BY INSTALLING OR USING SUCH SOFTWARE, YOU AGREE THAT YOU HAVE READ AND AGREE TO BE BOUND BY THE TERMS AND CONDITIONS OF THIS TSL AGREEMENT. IF YOU DO NOT AGREE WITH SUCH TERMS AND CONDITIONS, YOU MAY NOT INSTALL OR USE SUCH SOFTWARE. IF YOU ARE INSTALLING OR USING SUCH SOFTWARE ON BEHALF OF A LEGAL ENTITY, YOU REPRESENT AND WARRANT THAT YOU HAVE THE AUTHORITY TO AGREE TO THE TERMS AND CONDITIONS OF THIS TSL AGREEMENT ON BEHALF OF THAT LEGAL ENTITY AND THE RIGHT TO BIND THAT LEGAL ENTITY TO THIS TSL AGREEMENT. This TSL Agreement is entered into by and between Timescale, Inc. ("Timescale") and you or the legal entity on whose behalf you are accepting this TSL Agreement ("You"). 0. BACKGROUND The Timescale time-series database software and related software is offered as "open code" or "source-available" code. This means that all source code of the software is available for inspection and download at https://github.com/timescale. The Timescale software is composed of two major pieces. The first, core piece (referred to herein as the Timescale Open Source Software, as defined below) is open source software that is licensed under the Apache Version 2.0 license. The second piece (referred to herein as the TSL Licensed Software, as defined below) is all of the Timescale Software other than the Timescale Open Source Software. Certain functions or features of the TSL Licensed Software (referred to herein as Community Features, as defined below) may be used under this TSL Agreement without charge, in some cases subject to certain usage limits that may be imposed by a software license key and/or technical restrictions in the code. Certain other functions or features of the TSL Licensed Software (referred to herein as Enterprise Features, as defined below) may be used either solely under a Commercial License Agreement subject to charge, or under this TSL Agreement without charge only for a limited time trial period. In order to use such features, You must obtain an appropriate license key. You may find more information at https://www.timescale.com/pricing about which functions and features of the TSL Licensed Software are classified as Community Features and Enterprise Features, details about any applicable usage limits and trial periods, and a description of how You can obtain any required license keys and enter into a Commercial License Agreement with Timescale. 1.
