6. Commercial Usage

(a) Commercial Exploitation of the Work or Derivative Works is prohibited.

(b) Clarification: The prohibition in Section 6(a) specifically applies to monetization of the Work or Derivative Works themselves.

Acceptance of voluntary donations is permitted provided:

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. In the event of conflict between a separate agreement and this License, the separate agreement shall prevail with respect to this License.

9. Trademarks. This License does not grant permission to use the trade names, trademarks, service marks, or product names of the Licensor, except as expressly permitted in Sections 4(c) and 5(b) for descriptive reference purposes and reproducing the content of the NOTICE file.

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. This disclaimer applies with heightened emphasis to any unofficial versions or Derivative Works.

11. 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.

12. 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. For avoidance of doubt, such value-added services shall not constitute "Commercial Exploitation" as defined in Section 6 provided they:

(a) Do not restrict access to the Core Functionality of the Work or Derivative Works; and

(b) Are clearly separate offerings from the distribution of the Work itself.
