<p>Creative Commons Corporation (&quot;Creative Commons&quot;) 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 &quot;as-is&quot; basis.

<p>Using Creative Commons Public Licenses</p>

<p>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.</p>

<p> 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.

<p> 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.

<p>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 (&quot;Public License&quot;). To the extent this Public License may be interpreted as a contract, You are granted the Licensed Rights in consideration of Your acceptance of these terms and conditions, and the Licensor grants You such rights in consideration of benefits the Licensor receives from making the Licensed Material available under these terms and conditions.</p>

<p> Section 1 -- Definitions.</p>

<p> a. Adapted Material means material subject to Copyright and Similar  Rights that 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 the  Licensor. For purposes of this Public License, where the Licensed  Material is a musical work, performance, or sound recording,  Adapted Material is always produced where the Licensed Material is  synched in timed relation with a moving image.</p>

<p> c. BY-SA Compatible License means a license listed at  creativecommons.org/compatiblelicenses, approved by Creative  Commons as essentially the equivalent of this Public License.</p>

<p> 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.</p>

<p> 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.</p>

<p> 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.</p>

<p> g. License Elements means the license attributes listed in the name  of a Creative Commons Public License. The License Elements of this  Public License are Attribution and ShareAlike.</p>

<p> h. Licensed Material means the artistic or literary work, database,  or other material to which the Licensor applied this Public  License.</p>

<p> i. Licensed Rights means the rights granted to You subject to the  terms and conditions of this Public License, which are limited to  all Copyright and Similar Rights that apply to Your use of the  Licensed Material and that the Licensor has authority to license.</p>

<p> 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 display, public performance, distribution,  dissemination, communication, or importation, and to make material  available to the public including in ways that members of the  public may access the material from a place and at a time  individually chosen by them.</p>

<p> 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 as other essentially  equivalent rights anywhere in the world.</p>

<p> m. You means the individual or entity exercising the Licensed Rights  under this Public License. Your has a corresponding meaning.</p>

<p> Section 2 -- Scope.</p>

<p> a. License grant.</p>

<p> 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:</p>

<p> a. reproduce and Share the Licensed Material, in whole or  in part; and</p>

<p> b. produce, reproduce, and Share Adapted Material.</p>

<p> 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.</p>

<p> 3. Term. The term of this Public License is specified in Section  6(a).</p>

<p> 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.</p>

<p> 5. Downstream recipients.</p>

<p> 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.</p>

<p> 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.</p>

<p> 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.</p>

<p> 6. No endorsement. 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).</p>

<p> b. Other rights.</p>

<p> 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.</p>

<p> 2. Patent and trademark rights are not licensed under this  Public License.</p>

<p> 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.</p>

<p> Section 3 -- License Conditions.</p>

<p>Your exercise of the Licensed Rights is expressly made subject to the following conditions.</p>

<p> a. Attribution.</p>

<p> 1. If You Share the Licensed Material (including in modified  form), You must:</p>

<p> a. retain the following if it is supplied by the Licensor  with the Licensed Material:</p>

<p> 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);</p>

<p> ii. a copyright notice;</p>

<p> iii. a notice that refers to this Public License;</p>

<p> iv. a notice that refers to the disclaimer of  warranties;</p>

<p> v. a URI or hyperlink to the Licensed Material to the  extent reasonably practicable;</p>

<p> b. indicate if You modified the Licensed Material and  retain an indication of any previous modifications; and</p>

<p> 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.</p>

<p> 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.</p>

<p> 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.</p>

<p> b. ShareAlike.</p>

<p> In addition to the conditions in Section 3(a), if You Share  Adapted Material You produce, the following conditions also apply.</p>

<p> 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-SA Compatible License.</p>

<p> 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.</p>

<p> 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.</p>

<p> Section 4 -- Sui Generis Database Rights.</p>

<p>Where the Licensed Rights include Sui Generis Database Rights that apply to Your use of the Licensed Material:</p>

<p> 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;</p>

<p> 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,</p>

<p> 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.</p>

<p>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.</p>

<p> Section 5 -- Disclaimer of Warranties and Limitation of Liability.</p>

<p> 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.</p>

<p> 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.</p>

<p> 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.</p>

<p> Section 6 -- Term and Termination.</p>

<p> 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.</p>

<p> b. Where Your right to use the Licensed Material has terminated under  Section 6(a), it reinstates:</p>

<p> 1. automatically as of the date the violation is cured, provided  it is cured within 30 days of Your discovery of the  violation; or</p>

<p> 2. upon express reinstatement by the Licensor.</p>

<p> 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.</p>

<p> c. 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.</p>

<p> d. Sections 1, 5, 6, 7, and 8 survive termination of this Public  License.</p>

<p> Section 7 -- Other Terms and Conditions.</p>

<p> a. The Licensor shall not be bound by any additional or different  terms or conditions communicated by You unless expressly agreed.</p>

<p> 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.</p>

<p> Section 8 -- Interpretation.</p>

<p> 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.</p>

<p> 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.</p>

<p> 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.</p>

<p> 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.</p>
