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.  Creative Commons

By exercising the Licensed Rights (defined below), You accept and agree to be
bound by the terms and conditions of this Creative Commons
Attribution-NonCommercial-NoDerivatives 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.  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.

c.  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.

d.  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.

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

f.  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.

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

h.  NonCommercial means not primarily intended for or directed towards
commercial advantage or monetary compensation. For purposes of this Public
License, the exchange of the Licensed Material for other material subject to
Copyright and Similar Rights by digital file-sharing or similar means is
NonCommercial provided there is no payment of monetary compensation in
connection with the exchange.

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, for
NonCommercial purposes only; and

B. produce and reproduce, but not Share, Adapted Material for NonCommercial
purposes only.

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, 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, 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. For the avoidance of doubt, You do not have permission under this Public
License to Share Adapted Material.

3. 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.

4. If requested by the Licensor, You must remove any of the information required
by Section 3(a)(1)(A) to the extent reasonably practicable.

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 and provided You do not Share Adapted
Material;

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.

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.

Creative Commons is not a party to its public licenses. Notwithstanding,
Creative Commons may elect to apply one of its public licenses to material it
publishes and in those instances will be considered the “Licensor.” Except for
the limited purpose of indicating that material is shared under a Creative
Commons public license or as otherwise permitted by the Creative Commons
