      does not provide legal services or legal advice. Distribution of
      Creative Commons public licenses does not create a lawyer-client or

      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

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


      Section 1 -- Definitions.

        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.

        b. Adapter's License means the license You apply to Your Copyright
           and Similar Rights in Your contributions to Adapted Material in
           accordance with the terms and conditions of this Public License.

        c. 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.

        d. 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.

        e. Exceptions and Limitations means fair use, fair dealing, and/or

           that applies to Your use of the Licensed Material.

           or other material to which the Licensor applied this Public
           License.

        g. 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.

        h. Licensor means the individual(s) or entity(ies) granting rights
           under this Public License.

        i. 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.

        j. 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.

        k. You means the individual or entity exercising the Licensed Rights
           under this 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.

             5. Downstream recipients.

                  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. 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. 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).

        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.

      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.

             4. If You Share Adapted Material You produce, the Adapter's
                License You apply must not prevent recipients of the Adapted
                Material from complying with this Public License.


      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;

        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; 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.

           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.

        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.

        d. 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.
