 Creative Commons Corporation (“Creative Commons”) is not a law firm and does
 not provide legal services or legal advice. Distribution of Creative Commons
 public licenses does not create a lawyer-client or other relationship. Creative
 Commons makes its licenses and related information available on an “as-is”
 basis. Creative Commons gives no warranties regarding its licenses, any
 material licensed under their terms and conditions, or any related information.
 Creative Commons disclaims all liability for damages resulting from their use
 to the fullest extent possible. Using Creative Commons Public Licenses Creative
 Commons public licenses provide a standard set of terms and conditions that
 creators and other rights holders may use to share original works of authorship
 and other material subject to copyright and certain other rights specified in
 the public license below. The following considerations are for informational
 purposes only, are not exhaustive, and do not form part of our licenses.
 Considerations for licensors: Our public licenses are intended for use by those
 authorized to give the public permission to use material in ways otherwise
 restricted by copyright and certain other rights. Our licenses are irrevocable.
 Licensors should read and understand the terms and conditions of the license
 they choose before applying it. Licensors should also secure all rights
 necessary before applying our licenses so that the public can reuse the
 material as expected. Licensors should clearly mark any material not subject to
 the license. This includes other CC-licensed material, or material used under
 an exception or limitation to copyright. More considerations for licensors.
 Considerations for the public: By using one of our public licenses, a licensor
 grants the public permission to use the licensed material under specified terms
 and conditions. If the licensor’s permission is not necessary for any
 reason–for example, because of any applicable exception or limitation to
 copyright–then that use is not regulated by the license. Our licenses grant
 only permissions under copyright and certain other rights that a licensor has
 authority to grant. Use of the licensed material may still be restricted for
 other reasons, including because others have copyright or other rights in the
 material. A licensor may make special requests, such as asking that all changes
 be marked or described. Although not required by our licenses, you are
 encouraged to respect those requests where reasonable. More considerations for
 the public.

 By exercising the Licensed Rights (defined below), You accept and agree to be
 bound by the terms and conditions of this Creative Commons
 Attribution-ShareAlike 4.0 International Public License ("Public License"). To

 benefits the Licensor receives from making the Licensed Material available
 under these terms and conditions.

 is derived from or based upon the Licensed Material and in which the Licensed
 Material is translated, altered, arranged, transformed, or otherwise modified
 in a manner requiring permission under the Copyright and Similar Rights held by

 Rights in Your contributions to Adapted Material in accordance with the terms
 and conditions of this Public License.

 essentially the equivalent of this Public License.
 .
 d. Copyright and Similar Rights means copyright and/or similar rights closely
 related to copyright including, without limitation, performance, broadcast,
 sound recording, and Sui Generis Database Rights, without regard to how the
 rights are labeled or categorized. For purposes of this Public License, the
 rights specified in Section 2(b)(1)-(2) are not Copyright and Similar Rights.
 .
 e. Effective Technological Measures means those measures that, in the absence
 of proper authority, may not be circumvented under laws fulfilling obligations
 under Article 11 of the WIPO Copyright Treaty adopted on December 20, 1996,
 and/or similar international agreements.
 .
 f. Exceptions and Limitations means fair use, fair dealing, and/or any other
 exception or limitation to Copyright and Similar Rights that applies to Your
 use of the Licensed Material.

 Creative Commons Public License. The License Elements of this Public License
 are Attribution and ShareAlike.
 .
 h. Licensed Material means the artistic or literary work, database, or other
 material to which the Licensor applied this Public License.

 Public License.
 .
 k. Share means to provide material to the public by any means or process that
 requires permission under the Licensed Rights, such as reproduction, public

 that members of the public may access the material from a place and at a time
 individually chosen by them.
 .
 l. Sui Generis Database Rights means rights other than copyright resulting from
 Directive 96/9/EC of the European Parliament and of the Council of 11 March
 1996 on the legal protection of databases, as amended and/or succeeded, as well

 .

 Public License. Your has a corresponding meaning.
 .
 Section 2 – Scope.
 .
 a. License grant.
 .
 1. Subject to the terms and conditions of this Public License, the Licensor
 hereby grants You a worldwide, royalty-free, non-sublicensable, non-exclusive,
 irrevocable license to exercise the Licensed Rights in the Licensed Material
 to:
 .
 A. reproduce and Share the Licensed Material, in whole or in part; and
 .
 B. produce, reproduce, and Share Adapted Material.

 2. Exceptions and Limitations. For the avoidance of doubt, where Exceptions and
 Limitations apply to Your use, this Public License does not apply, and You do
 not need to comply with its terms and conditions.
 .
 3. Term. The term of this Public License is specified in Section 6(a).
 .
 4. Media and formats; technical modifications allowed. The Licensor authorizes
 You to exercise the Licensed Rights in all media and formats whether now known
 or hereafter created, and to make technical modifications necessary to do so.
 The Licensor waives and/or agrees not to assert any right or authority to
 forbid You from making technical modifications necessary to exercise the
 Licensed Rights, including technical modifications necessary to circumvent
 Effective Technological Measures. For purposes of this Public License, simply
 making modifications authorized by this Section 2(a)(4) never produces Adapted
 Material.

 A. Offer from the Licensor – Licensed Material. 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. Additional offer from the Licensor – Adapted Material. Every recipient of
 Adapted Material from You automatically receives an offer from the Licensor to
 exercise the Licensed Rights in the Adapted Material under the conditions of
 the Adapter’s License You apply.
 .
 C. 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.

 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.
 .
 Section 3 – License Conditions.

 conditions.

 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.

 same License Elements, this version or later, or a BY-SA Compatible License.
 .

 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;
 .
 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. 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. Nothing in this Public 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.
 .
