+2. Grant of Copyright License. Subject to the terms and conditions of
+this License, each Contributor hereby grants to You a perpetual,
+worldwide, non-exclusive, no-charge, royalty-free, irrevocable

+Work and such Derivative Works in Source or Object form.
+
+3. Grant of Patent License. Subject to the terms and conditions of
+this License, each Contributor hereby grants to You a perpetual,
+worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+(except as stated in this section) patent license to make, have made,
+use, offer to sell, sell, import, and otherwise transfer the Work
+solely as incorporated into a Tizen Certified Platform, where such
+license applies only to those patent claims licensable by such
+Contributor that are necessarily infringed by their Contribution(s)
+alone or by combination of their Contribution(s) with the Work solely
+as incorporated into a Tizen Certified Platform to which such
+Contribution(s) was submitted. If You institute patent litigation
+against any entity (including a cross-claim or counterclaim
+in a lawsuit) alleging that the Work or a Contribution incorporated
+within the Work constitutes direct or contributory patent infringement,
+then any patent licenses granted to You under this License for that
+Work shall terminate as of the date such litigation is filed.
+
+4. Redistribution. You may reproduce and distribute copies of the
+Work or Derivative Works thereof pursuant to the copyright license
+above, in any medium, with or without modifications, and in Source or
+Object form, provided that You meet the following conditions:

+ that You changed the files; and
+ 3. You must retain, in the Source form of any Derivative Works that
+ You distribute, all copyright, patent, trademark, and attribution
+ notices from the Source form of the Work, excluding those notices
+ that do not pertain to any part of the Derivative Works; and
+ 4. If the Work includes a "NOTICE" text file as part of its distribution,
+ then any Derivative Works that You distribute must include a readable
+ copy of the attribution notices contained within such NOTICE file,
+ excluding those notices that do not pertain to any part of
+ the Derivative Works, in at least one of the following places:
+ within a NOTICE text file distributed as part of the Derivative Works;
+ within the Source form or documentation, if provided along with the
+ Derivative Works; or, within a display generated by the Derivative Works,
+ if and wherever such third-party notices normally appear.
+ The contents of the NOTICE file are for informational purposes only
+ and do not modify the License. You may add Your own attribution notices
+ within Derivative Works that You distribute, alongside or as an addendum
+ to the NOTICE text from the Work, provided that such additional attribution
+ notices cannot be construed as modifying the License. You may add Your own
+ copyright statement to Your modifications and may provide additional or
+ different license terms and conditions for use, reproduction, or
+ distribution of Your modifications, or for any such Derivative Works
+ as a whole, provided Your use, reproduction, and distribution of
+ the Work otherwise complies with the conditions stated in this License
+ and your own copyright statement or terms and conditions do not conflict
+ the conditions stated in the License including section 3.
+
+5. Submission of Contributions. Unless You explicitly state otherwise,
+any Contribution intentionally submitted for inclusion in the Work
+by You to the Licensor shall be under the terms and conditions of
+this License, without any additional terms or conditions.
+Notwithstanding the above, nothing herein shall supersede or modify
+the terms of any separate license agreement you may have executed
+with Licensor regarding such Contributions.
+
+6. Trademarks. This License does not grant permission to use the trade
+names, trademarks, service marks, or product names of the Licensor,
+except as required for reasonable and customary use in describing the
+origin of the Work and reproducing the content of the NOTICE file.
+
+7. Disclaimer of Warranty. Unless required by applicable law or
+agreed to in writing, Licensor provides the Work (and each
+Contributor provides its Contributions) on an "AS IS" BASIS,
+WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+implied, including, without limitation, any warranties or conditions
+of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+PARTICULAR PURPOSE. You are solely responsible for determining the
+appropriateness of using or redistributing the Work and assume any
+risks associated with Your exercise of permissions under this License.
+
+8. Limitation of Liability. In no event and under no legal theory,
+whether in tort (including negligence), contract, or otherwise,
+unless required by applicable law (such as deliberate and grossly
+negligent acts) or agreed to in writing, shall any Contributor be
+liable to You for damages, including any direct, indirect, special,
+incidental, or consequential damages of any character arising as a
+result of this License or out of the use or inability to use the
+Work (including but not limited to damages for loss of goodwill,
+work stoppage, computer failure or malfunction, or any and all
+other commercial damages or losses), even if such Contributor
+has been advised of the possibility of such damages.
+
+9. Accepting Warranty or Additional Liability. While redistributing
+the Work or Derivative Works thereof, You may choose to offer,
+and charge a fee for, acceptance of support, warranty, indemnity,
+or other liability obligations and/or rights consistent with this
+License. However, in accepting such obligations, You may act only
+on Your own behalf and on Your sole responsibility, not on behalf
+of any other Contributor, and only if You agree to indemnify,
+defend, and hold each Contributor harmless for any liability
+incurred by, or claims asserted against, such Contributor by reason
+of your accepting any such warranty or additional liability.
