If requested by the Licensor, You must remove any of the information required +by Section 3(a)(1)(A) to the extent reasonably practicable. + +4.

Where a limitation +of liability is not allowed in full or in part, this limitation may not apply +to You. + +c. The disclaimer of warranties and limitation of liability provided above +shall be interpreted in a manner that, to the extent possible, most closely +approximates an absolute disclaimer and waiver of all liability. + +Section 6 – Term and Termination. + +a. This Public License applies for the term of the Copyright and Similar Rights +licensed here. However, if You fail to comply with this Public License, then +Your rights under this Public License terminate automatically. + +b. Where Your right to use the Licensed Material has terminated under Section +6(a), it reinstates: + +1. automatically as of the date the violation is cured, provided it is cured +within 30 days of Your discovery of the violation; or + + 2. upon express reinstatement by the Licensor. + +c. For the avoidance of doubt, this Section 6(b) does not affect any right +the Licensor may have to seek remedies for Your violations of this Public +License. + +d. For the avoidance of doubt, the Licensor may also offer the Licensed Material +under separate terms or conditions or stop distributing the Licensed Material +at any time; however, doing so will not terminate this Public License. + + e. Sections 1, 5, 6, 7, and 8 survive termination of this Public License. + +Section 7 – Other Terms and Conditions. + +a. The Licensor shall not be bound by any additional or different terms or +conditions communicated by You unless expressly agreed. + +b. Any arrangements, understandings, or agreements regarding the Licensed +Material not stated herein are separate from and independent of the terms +and conditions of this Public License. + +Section 8 – Interpretation. + +a. For the avoidance of doubt, this Public License does not, and shall not +be interpreted to, reduce, limit, restrict, or impose conditions on any use +of the Licensed Material that could lawfully be made without permission under +this Public License. + +b. To the extent possible, if any provision of this Public 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 Public License without affecting the enforceability of the remaining +terms and conditions. + +c. No term or condition of this Public License will be waived and no failure +to comply consented to unless expressly agreed to by the Licensor. + +d.
