For purposes of this Public License, simply making modifications + authorized by this Section 2(a)(4) never produces Adapted Material. + + 5. Downstream recipients. + + A.

Every + recipient of the Licensed Material automatically receives an offer from the + Licensor to exercise the Licensed Rights under the terms and conditions of + this Public License. + + B.

No downstream restrictions. You may not offer or impose + any additional or different terms or conditions on, or apply any Effective + Technological Measures to, the Licensed Material if doing so restricts + exercise of the Licensed Rights by any recipient of the Licensed Material. + + 6.

Nothing in this Public License constitutes or + may be construed as permission to assert or imply that You are, or that + Your use of the Licensed Material is, connected with, or sponsored, + endorsed, or granted official status by, the Licensor or others designated + to receive attribution as provided in Section 3(a)(1)(A)(i). + + b. Other rights. + + 1. Moral rights, such as the right of integrity, are not licensed + under this Public License, nor are publicity, privacy, and/or other similar + personality rights; however, to the extent possible, the Licensor waives + and/or agrees not to assert any such rights held by the Licensor to the + limited extent necessary to allow You to exercise the Licensed Rights, but + not otherwise. + + 2. Patent and trademark rights are not licensed under this Public + License. + + 3. To the extent possible, the Licensor waives any right to + collect royalties from You for the exercise of the Licensed Rights, whether + directly or through a collecting society under any voluntary or waivable + statutory or compulsory licensing scheme. In all other cases the Licensor + expressly reserves any right to collect such royalties, including when the + Licensed Material is used other than for NonCommercial purposes. + +Section 3 – License Conditions. + +Your exercise of the Licensed Rights is expressly made subject to the +following conditions. + + a. Attribution. + + 1. If You Share the Licensed Material (including in modified + form), You must: + + A. retain the following if it is supplied by the Licensor + with the Licensed Material: + + i. identification of the creator(s) of the Licensed + Material and any others designated to receive attribution, in any + reasonable manner requested by the Licensor (including by pseudonym if + designated); + + ii. a copyright notice; + + iii. a notice that refers to this Public License; + + iv. a notice that refers to the disclaimer of + warranties; + + v. a URI or hyperlink to the Licensed Material to the + extent reasonably practicable; + + B. indicate if You modified the Licensed Material and retain + an indication of any previous modifications; and + + C. indicate the Licensed Material is licensed under this + Public License, and include the text of, or the URI or hyperlink to, this + Public License. + + 2. You may satisfy the conditions in Section 3(a)(1) in any + reasonable manner based on the medium, means, and context in which You + Share the Licensed Material. For example, it may be reasonable to satisfy + the conditions by providing a URI or hyperlink to a resource that includes + the required information. + + 3. If requested by the Licensor, You must remove any of the + information required by Section 3(a)(1)(A) to the extent reasonably + practicable. + + b. ShareAlike.In addition to the conditions in Section 3(a), if You + Share Adapted Material You produce, the following conditions also apply. + + 1. The Adapter’s License You apply must be a Creative Commons + license with the same License Elements, this version or later, or a + BY-NC-SA Compatible License. + + 2. You must include the text of, or the URI or hyperlink to, the + Adapter's License You apply. You may satisfy this condition in any + reasonable manner based on the medium, means, and context in which You + Share Adapted Material. + + 3. You may not offer or impose any additional or different terms + or conditions on, or apply any Effective Technological Measures to, Adapted + Material that restrict exercise of the rights granted under the Adapter's + License You apply. + +Section 4 – Sui Generis Database Rights. + +Where the Licensed Rights include Sui Generis Database Rights that apply to +Your use of the Licensed Material: + + a. for the avoidance of doubt, Section 2(a)(1) grants You the right to + extract, reuse, reproduce, and Share all or a substantial portion of the + contents of the database for NonCommercial purposes only; + + b. if You include all or a substantial portion of the database + contents in a database in which You have Sui Generis Database Rights, then + the database in which You have Sui Generis Database Rights (but not its + individual contents) is Adapted Material, including for purposes of Section + 3(b); and + + c. You must comply with the conditions in Section 3(a) if You Share + all or a substantial portion of the contents of the database. +For the avoidance of doubt, this Section 4 supplements and does not replace +Your obligations under this Public License where the Licensed Rights +include other Copyright and Similar Rights. + +Section 5 – Disclaimer of Warranties and Limitation of Liability. + + a. Unless otherwise separately undertaken by the Licensor, to the + extent possible, the Licensor offers the Licensed Material as-is and + as-available, and makes no representations or warranties of any kind + concerning the Licensed Material, whether express, implied, statutory, or + other. This includes, without limitation, warranties of title, + merchantability, fitness for a particular purpose, non-infringement, + absence of latent or other defects, accuracy, or the presence or absence of + errors, whether or not known or discoverable. Where disclaimers of + warranties are not allowed in full or in part, this disclaimer may not + apply to You. + + b. To the extent possible, in no event will the Licensor be liable to + You on any legal theory (including, without limitation, negligence) or + otherwise for any direct, special, indirect, incidental, consequential, + punitive, exemplary, or other losses, costs, expenses, or damages arising + out of this Public License or use of the Licensed Material, even if the + Licensor has been advised of the possibility of such losses, costs, + expenses, or damages. 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.
