Version 1.01, August 5th, 2008
We want people to be able to build Free/Libre and Open Source Software ("FLOSS") applications using Ext development libraries despite the fact that not all FLOSS licenses are compatible with version 3.0 of the GNU General Public License (the "GPL").
This Exception is intended to be used for end-user applications and is not intended to be applied to software development libraries or toolkits, as per section 2(d) below. For development libraries, please refer to the Open Source License Exception for Development.
As a special exception to the terms and conditions of version 3.0 of the GPL:
You are free to distribute a Derivative Work that is formed entirely from the Library and one or more works (each, a “FLOSS Work”) licensed under one or more of the licenses listed below in section 5, as long as:
This exception applies to Ext JS version 2.2 or later and Ext GWT version 1.0 or later released under the GPL that contain a notice placed by Ext JS, LLC saying that Derivative Works built using the Library may be distributed under the terms of this Exception.
If you fail to comply with any of the terms in this Exception then all rights granted to you herein are void and your rights immediately revert back to those granted in the GPL v3.
