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.

bound by the terms and conditions of this Creative Commons
Attribution-ShareAlike 4.0 International Public License ("Public License"). To
the extent this Public License may be interpreted as a contract, You are granted

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

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

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.

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.

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.

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

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

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.

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.

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

Section 2 – Scope.

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.

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.

same License Elements, this version or later, or a BY-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;

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.

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

Material not stated herein are separate from and independent of the terms and

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.
