If Your 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. ### Section 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.

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. ### Section 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.

Without limiting the generality of the foregoing, You are responsible for the Software Applications and their use of the Work, if any. You agree to indemnify, defend, and hold harmless all Contributors and their officers, directors, employees, agents, affiliates, successors, and assigns from and against any and all losses, damages, liabilities, deficiencies, claims, actions, judgments, settlements, interest, awards, penalties, fines, costs, or expenses of whatever kind, including attorneys’ fees, arising from or relating to (a) Your use or misuse of the Work, (b) Your breach of this Agreement, and/or (c) the Software Applications. You may not enter into any third-party agreement that would, in any manner whatsoever, constitute an admission of fault by Contributors or bind Contributors in any way, without prior written consent of all affected Contributors. ### Section 9.

While redistributing the Work, You may choose to offer acceptance of support, warranty, indemnity, or other liability obligations and/or rights consistent with this License.

Term and Termination. 10.1 This License applies for the term of the copyrights licensed here. However, if You fail to comply with this License, then Your rights under this License terminate automatically. 10.2 Where Your right to use the Work has terminated under Section 10, it reinstates: a. automatically as of the date the violation is cured, provided it is cured within 30 days of Your discovery of the violation; or b. upon express reinstatement by the Licensor. For the avoidance of doubt, this Section 10 does not affect any right the Licensor may have to seek remedies for Your violations of this License. 10.3 For the avoidance of doubt, the Licensor may also offer the Work under separate terms or conditions or stop distributing the Work at any time; however, doing so will not terminate this License. 10.4 Sections 1, 7, 10, and 12 survive termination of this License. ### Section 11. Other Terms and Conditions. 11.1 The Licensor shall not be bound by any additional or different terms or conditions communicated by You unless expressly agreed. 11.2 Any arrangements, understandings, or agreements regarding the Work not stated herein are separate from and independent of the terms and conditions of this License. ### Section 12. Interpretation. 12.1 For the avoidance of doubt, this License does not, and shall not be interpreted to, reduce, limit, restrict, or impose conditions on any use of the Work that could lawfully be made without permission under this License. 12.2 To the extent possible, if any provision of this License is deemed unenforceable, it shall be automatically reformed to the minimum extent necessary to make it enforceable. If the provision cannot be reformed, it shall be severed from this License without affecting the enforceability of the remaining terms and conditions. 12.3 No term or condition of this License will be waived and no failure to comply consented to unless expressly agreed to by the Licensor. 12.4 Nothing in this License constitutes or may be interpreted as a limitation upon, or waiver of, any privileges and immunities that apply to the Licensor or You, including from the legal processes of any jurisdiction or authority. ## END OF TERMS AND CONDITIONS ### APPENDIX: How to apply the UCUM License to your work.
