+
+PLEASE REVIEW THE FOLLOWING TERMS AND CONDITIONS PRIOR TO USING THE

+OF THE SOFTWARE IS SUBJECT TO THE TERMS AND CONDITIONS OF THE
+FOLLOWING SOFTWARE LICENSE AGREEMENT (THE "SLA"). IF YOU DO NOT ACCEPT
+SUCH TERMS AND CONDITIONS YOU MAY NOT USE THE SOFTWARE.
+
+Subject to the terms and conditions of the SLA, the licensee of the
+Software (the "Licensee") hereby, receives a non-exclusive,
+non-transferable, limited, free-of-charge, perpetual and worldwide
+license, to copy, use, distribute and modify the Software, but only
+for the purpose of developing, manufacturing, selling, using and
+distributing products including the Software in binary form, which
+products are used for compression and/or decompression according to
+the Khronos standard specifications OpenGL, OpenGL ES and
+WebGL. Notwithstanding anything of the above, Licensee may distribute
+[etcdec.cxx] in source code form provided (i) it is in unmodified
+form; and (ii) it is included in software owned by Licensee.
+
+If Licensee institutes, or threatens to institute, patent litigation
+against Ericsson or Ericsson's affiliates for using the Software for
+developing, having developed, manufacturing, having manufactured,

+repairing and/or distributing products (i) within the scope of the
+Khronos framework; or (ii) using software or other intellectual
+property rights owned by Ericsson or its affiliates and provided under
+the Khronos framework, Ericsson shall have the right to terminate this
+SLA with immediate effect. Moreover, if Licensee institutes, or
+threatens to institute, patent litigation against any other licensee
+of the Software for using the Software in products within the scope of
+the Khronos framework, Ericsson shall have the right to terminate this
+SLA with immediate effect. However, should Licensee institute, or
+threaten to institute, patent litigation against any other licensee of
+the Software based on such other licensee's use of any other software
+together with the Software, then Ericsson shall have no right to
+terminate this SLA.
+
+This SLA does not transfer to Licensee any ownership to any Ericsson
+or third party intellectual property rights. All rights not expressly
+granted by Ericsson under this SLA are hereby expressly
+reserved. Furthermore, nothing in this SLA shall be construed as a
+right to use or sell products in a manner which conveys or purports to
+convey whether explicitly, by principles of implied license, or
+otherwise, any rights to any third party, under any patent of Ericsson
+or of Ericsson's affiliates covering or relating to any combination of
+the Software with any other software or product (not licensed
+hereunder) where the right applies specifically to the combination and
+not to the software or product itself.
+
+THE SOFTWARE IS PROVIDED "AS IS". ERICSSON MAKES NO REPRESENTATIONS OF
+ANY KIND, EXTENDS NO WARRANTIES OR CONDITIONS OF ANY KIND, EITHER
+EXPRESS, IMPLIED OR STATUTORY; INCLUDING, BUT NOT LIMITED TO, EXPRESS,

+PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE
+OF THE SOFTWARE IS WITH THE LICENSEE. SHOULD THE SOFTWARE PROVE
+DEFECTIVE, THE LICENSEE ASSUMES THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION. ERICSSON MAKES NO WARRANTY THAT THE MANUFACTURE,
+SALE, OFFERING FOR SALE, DISTRIBUTION, LEASE, USE OR IMPORTATION UNDER
+THE SLA WILL BE FREE FROM INFRINGEMENT OF PATENTS, COPYRIGHTS OR OTHER
+INTELLECTUAL PROPERTY RIGHTS OF OTHERS, AND THE VALIDITY OF THE
+LICENSE AND THE SLA ARE SUBJECT TO LICENSEE'S SOLE RESPONSIBILITY TO
+MAKE SUCH DETERMINATION AND ACQUIRE SUCH LICENSES AS MAY BE NECESSARY
+WITH RESPECT TO PATENTS, COPYRIGHT AND OTHER INTELLECTUAL PROPERTY OF
+THIRD PARTIES.
+
+THE LICENSEE ACKNOWLEDGES AND ACCEPTS THAT THE SOFTWARE (I) IS NOT
+LICENSED FOR; (II) IS NOT DESIGNED FOR OR INTENDED FOR; AND (III) MAY
+NOT BE USED FOR; ANY MISSION CRITICAL APPLICATIONS SUCH AS, BUT NOT
+LIMITED TO OPERATION OF NUCLEAR OR HEALTHCARE COMPUTER SYSTEMS AND/OR
+NETWORKS, AIRCRAFT OR TRAIN CONTROL AND/OR COMMUNICATION SYSTEMS OR
+ANY OTHER COMPUTER SYSTEMS AND/OR NETWORKS OR CONTROL AND/OR
+COMMUNICATION SYSTEMS ALL IN WHICH CASE THE FAILURE OF THE SOFTWARE
+COULD LEAD TO DEATH, PERSONAL INJURY, OR SEVERE PHYSICAL, MATERIAL OR
+ENVIRONMENTAL DAMAGE. LICENSEE'S RIGHTS UNDER THIS LICENSE WILL
+TERMINATE AUTOMATICALLY AND IMMEDIATELY WITHOUT NOTICE IF LICENSEE
+FAILS TO COMPLY WITH THIS PARAGRAPH.
+
+IN NO EVENT SHALL ERICSSON BE LIABLE FOR ANY DAMAGES WHATSOEVER,
+INCLUDING BUT NOT LIMITED TO PERSONAL INJURY, ANY GENERAL, SPECIAL,
+INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES, ARISING OUT OF OR IN
+CONNECTION WITH THE USE OR INABILITY TO USE THE SOFTWARE (INCLUDING
+BUT NOT LIMITED TO LOSS OF PROFITS, BUSINESS INTERUPTIONS, OR ANY
+OTHER COMMERCIAL DAMAGES OR LOSSES, LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY THE LICENSEE OR THIRD
+PARTIES OR A FAILURE OF THE SOFTWARE TO OPERATE WITH ANY OTHER
+SOFTWARE) REGARDLESS OF THE THEORY OF LIABILITY (CONTRACT, TORT, OR
