AUTHORIZED UNDER THIS LICENSE OR COPYRIGHT LAW IS PROHIBITED.

work, arrangement of music or other alterations of a literary or
artistic work, or phonogram or performance and includes cinematographic
adaptations or any other form in which the Work may be recast,
transformed, or adapted including in any form recognizably derived from
the original, except that a work that constitutes a Collection will not
be considered an Adaptation for the purpose of this License. For the
avoidance of doubt, where the Work is a musical work, performance or
phonogram, the synchronization of the Work in timed-relation with a
moving image ("synching") will be considered an Adaptation for the
purpose of this License.
․
b. "Collection" means a collection of literary or artistic works, such
as encyclopedias and anthologies, or performances, phonograms or
broadcasts, or other works or subject matter other than works listed in
Section 1(f) below, which, by reason of the selection and arrangement of
their contents, constitute intellectual creations, in which the Work is
included in its entirety in unmodified form along with one or more other
contributions, each constituting separate and independent works in
themselves, which together are assembled into a collective whole. A work
that constitutes a Collection will not be considered an Adaptation (as
defined below) for the purposes of this License.

adaptations of works made available under that license under this
License or a Creative Commons jurisdiction license with the same License
Elements as this License.

play in, interpret or otherwise perform literary or artistic works or
expressions of folklore; (ii) in the case of a phonogram the producer
being the person or legal entity who first fixes the sounds of a

form of its expression including digital form, such as a book, pamphlet
and other writing; a lecture, address, sermon or other work of the same
nature; a dramatic or dramatico-musical work; a choreographic work or
entertainment in dumb show; a musical composition with or without words;

architecture or science; a performance; a broadcast; a phonogram; a
compilation of data to the extent it is protected as a copyrightable
work; or a work performed by a variety or circus performer to the extent
it is not otherwise considered a literary or artistic work.
․
i. "You" means an individual or entity exercising rights under this
License who has not previously violated the terms of this License with
respect to the Work, or who has received express permission from the
Licensor to exercise rights under this License despite a previous
violation.
․
j. "Publicly Perform" means to perform public recitations of the Work
and to communicate to the public those public recitations, by any means
or process, including by wire or wireless means or public digital
performances; to make available to the public Works in such a way that
members of the public may access these Works from a place and at a place
individually chosen by them; to perform the Work to the public by any
means or process and the communication to the public of the performances
of the Work, including by public digital performance; to broadcast and
rebroadcast the Work by any means including signs, sounds or images.

․
2. Fair Dealing Rights. Nothing in this License is intended to reduce,
limit, or restrict any uses free from copyright or rights arising from
limitations or exceptions that are provided for in connection with the
copyright protection under copyright law or other applicable laws.
․
3. License Grant. Subject to the terms and conditions of this License,
Licensor hereby grants You a worldwide, royalty-free, non-exclusive,
perpetual (for the duration of the applicable copyright) license to
exercise the rights in the Work as stated below:
․
a. to Reproduce the Work, to incorporate the Work into one or more
Collections, and to Reproduce the Work as incorporated in the
Collections;
․
b. to create and Reproduce Adaptations provided that any such
Adaptation, including any translation in any medium, takes reasonable
steps to clearly label, demarcate or otherwise identify that changes
were made to the original Work. For example, a translation could be
marked "The original work was translated from English to Spanish," or a
modification could indicate "The original work has been modified.";
․
c. to Distribute and Publicly Perform the Work including as incorporated
in Collections; and,
․
d. to Distribute and Publicly Perform Adaptations.
․
e. For the avoidance of doubt:
․
i. Non-waivable Compulsory License Schemes. In those jurisdictions in
which the right to collect royalties through any statutory or compulsory
licensing scheme cannot be waived, the Licensor reserves the exclusive
right to collect such royalties for any exercise by You of the rights
granted under this License;
․
ii. Waivable Compulsory License Schemes. In those jurisdictions in which
the right to collect royalties through any statutory or compulsory
licensing scheme can be waived, the Licensor waives the exclusive right
to collect such royalties for any exercise by You of the rights granted
under this License; and,
․
iii. Voluntary License Schemes. The Licensor waives the right to collect
royalties, whether individually or, in the event that the Licensor is a
member of a collecting society that administers voluntary licensing
schemes, via that society, from any exercise by You of the rights
granted under this License.
․
The above rights may be exercised in all media and formats whether now
known or hereafter devised. The above rights include the right to make
such modifications as are technically necessary to exercise the rights
in other media and formats. Subject to Section 8(f), all rights not
expressly granted by Licensor are hereby reserved.
․
4. Restrictions. The license granted in Section 3 above is expressly
made subject to and limited by the following restrictions:
․
a. You may Distribute or Publicly Perform the Work only under the terms
of this License. You must include a copy of, or the Uniform Resource
Identifier (URI) for, this License with every copy of the Work You
Distribute or Publicly Perform. You may not offer or impose any terms on
the Work that restrict the terms of this License or the ability of the
recipient of the Work to exercise the rights granted to that recipient
under the terms of the License. You may not sublicense the Work. You
must keep intact all notices that refer to this License and to the
disclaimer of warranties with every copy of the Work You Distribute or
Publicly Perform. When You Distribute or Publicly Perform the Work, You
may not impose any effective technological measures on the Work that
restrict the ability of a recipient of the Work from You to exercise the
rights granted to that recipient under the terms of the License. This
Section 4(a) applies to the Work as incorporated in a Collection, but
this does not require the Collection apart from the Work itself to be
made subject to the terms of this License. If You create a Collection,
upon notice from any Licensor You must, to the extent practicable,
remove from the Collection any credit as required by Section 4(c), as
requested. If You create an Adaptation, upon notice from any Licensor
You must, to the extent practicable, remove from the Adaptation any
credit as required by Section 4(c), as requested.
․
b. You may Distribute or Publicly Perform an Adaptation only under the
terms of: (i) this License; (ii) a later version of this License with
the same License Elements as this License; (iii) a Creative Commons
jurisdiction license (either this or a later license version) that
contains the same License Elements as this License (e.g.,
Attribution-ShareAlike 3.0 US)); (iv) a Creative Commons Compatible
License. If you license the Adaptation under one of the licenses
mentioned in (iv), you must comply with the terms of that license. If
you license the Adaptation under the terms of any of the licenses
mentioned in (i), (ii) or (iii) (the "Applicable License"), you must
comply with the terms of the Applicable License generally and the
following provisions: (I) You must include a copy of, or the URI for,
the Applicable License with every copy of each Adaptation You Distribute
or Publicly Perform; (II) You may not offer or impose any terms on the
Adaptation that restrict the terms of the Applicable License or the
ability of the recipient of the Adaptation to exercise the rights
granted to that recipient under the terms of the Applicable License;
(III) You must keep intact all notices that refer to the Applicable
License and to the disclaimer of warranties with every copy of the Work
as included in the Adaptation You Distribute or Publicly Perform; (IV)
when You Distribute or Publicly Perform the Adaptation, You may not
impose any effective technological measures on the Adaptation that
restrict the ability of a recipient of the Adaptation from You to
exercise the rights granted to that recipient under the terms of the
Applicable License. This Section 4(b) applies to the Adaptation as
incorporated in a Collection, but this does not require the Collection
apart from the Adaptation itself to be made subject to the terms of the
Applicable License.
․
c. If You Distribute, or Publicly Perform the Work or any Adaptations or
Collections, You must, unless a request has been made pursuant to
Section 4(a), keep intact all copyright notices for the Work and
provide, reasonable to the medium or means You are utilizing: (i) the
name of the Original Author (or pseudonym, if applicable) if supplied,
and/or if the Original Author and/or Licensor designate another party or
parties (e.g., a sponsor institute, publishing entity, journal) for
attribution ("Attribution Parties") in Licensor's copyright notice,
terms of service or by other reasonable means, the name of such party or
parties; (ii) the title of the Work if supplied; (iii) to the extent
reasonably practicable, the URI, if any, that Licensor specifies to be
associated with the Work, unless such URI does not refer to the
copyright notice or licensing information for the Work; and (iv) ,
consistent with Ssection 3(b), in the case of an Adaptation, a credit
identifying the use of the Work in the Adaptation (e.g., "French
translation of the Work by Original Author," or "Screenplay based on
original Work by Original Author"). The credit required by this Section
4(c) may be implemented in any reasonable manner; provided, however,
that in the case of a Adaptation or Collection, at a minimum such credit
will appear, if a credit for all contributing authors of the Adaptation
or Collection appears, then as part of these credits and in a manner at
least as prominent as the credits for the other contributing authors.
For the avoidance of doubt, You may only use the credit required by this
Section for the purpose of attribution in the manner set out above and,
by exercising Your rights under this License, You may not implicitly or
explicitly assert or imply any connection with, sponsorship or
endorsement by the Original Author, Licensor and/or Attribution Parties,
as appropriate, of You or Your use of the Work, without the separate,
express prior written permission of the Original Author, Licensor and/or
Attribution Parties.
․
d. Except as otherwise agreed in writing by the Licensor or as may be
otherwise permitted by applicable law, if You Reproduce, Distribute or
Publicly Perform the Work either by itself or as part of any Adaptations
or Collections, You must not distort, mutilate, modify or take other
derogatory action in relation to the Work which would be prejudicial to
the Original Author's honor or reputation. Licensor agrees that in those
jurisdictions (e.g. Japan), in which any exercise of the right granted
in Section 3(b) of this License (the right to make Adaptations) would be
deemed to be a distortion, mutilation, modification or other derogatory
action prejudicial to the Original Author's honor and reputation, the
Licensor will waive or not assert, as appropriate, this Section, to the
fullest extent permitted by the applicable national law, to enable You
to reasonably exercise Your right under Section 3(b) of this License
(right to make Adaptations) but not otherwise.
․
5. Representations, Warranties and Disclaimer
․
UNLESS OTHERWISE MUTUALLY AGREED TO BY THE PARTIES IN WRITING, LICENSOR
OFFERS THE WORK AS-IS AND MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY
KIND CONCERNING THE WORK, EXPRESS, IMPLIED, STATUTORY OR OTHERWISE,
INCLUDING, WITHOUT LIMITATION, WARRANTIES OF TITLE, MERCHANTIBILITY,
FITNESS FOR A PARTICULAR PURPOSE, NONINFRINGEMENT, OR THE ABSENCE OF
LATENT OR OTHER DEFECTS, ACCURACY, OR THE PRESENCE OF ABSENCE OF ERRORS,
WHETHER OR NOT DISCOVERABLE. SOME JURISDICTIONS DO NOT ALLOW THE
EXCLUSION OF IMPLIED WARRANTIES, SO SUCH EXCLUSION MAY NOT APPLY TO YOU.
․
6. Limitation on Liability. EXCEPT TO THE EXTENT REQUIRED BY APPLICABLE
LAW, IN NO EVENT WILL LICENSOR BE LIABLE TO YOU ON ANY LEGAL THEORY FOR
ANY SPECIAL, INCIDENTAL, CONSEQUENTIAL, PUNITIVE OR EXEMPLARY DAMAGES
ARISING OUT OF THIS LICENSE OR THE USE OF THE WORK, EVEN IF LICENSOR HAS
BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
․
7. Termination
․
a. This License and the rights granted hereunder will terminate
automatically upon any breach by You of the terms of this License.
Individuals or entities who have received Adaptations or Collections
from You under this License, however, will not have their licenses
terminated provided such individuals or entities remain in full
compliance with those licenses. Sections 1, 2, 5, 6, 7, and 8 will
survive any termination of this License.
․
b. Subject to the above terms and conditions, the license granted here
is perpetual (for the duration of the applicable copyright in the Work).
Notwithstanding the above, Licensor reserves the right to release the
Work under different license terms or to stop distributing the Work at
any time; provided, however that any such election will not serve to
withdraw this License (or any other license that has been, or is
required to be, granted under the terms of this License), and this
License will continue in full force and effect unless terminated as
stated above.
․
8. Miscellaneous
․
a. Each time You Distribute or Publicly Perform the Work or a
Collection, the Licensor offers to the recipient a license to the Work
on the same terms and conditions as the license granted to You under
this License.
․
b. Each time You Distribute or Publicly Perform an Adaptation, Licensor
offers to the recipient a license to the original Work on the same terms
and conditions as the license granted to You under this License.
․
c. If any provision of this License is invalid or unenforceable under
applicable law, it shall not affect the validity or enforceability of
the remainder of the terms of this License, and without further action
by the parties to this agreement, such provision shall be reformed to
the minimum extent necessary to make such provision valid and
enforceable.
․
d. No term or provision of this License shall be deemed waived and no
breach consented to unless such waiver or consent shall be in writing
and signed by the party to be charged with such waiver or consent.
․
e. This License constitutes the entire agreement between the parties
with respect to the Work licensed here. There are no understandings,
agreements or representations with respect to the Work not specified
here. Licensor shall not be bound by any additional provisions that may
appear in any communication from You. This License may not be modified
without the mutual written agreement of the Licensor and You.
․
f. The rights granted under, and the subject matter referenced, in this
License were drafted utilizing the terminology of the Berne Convention
for the Protection of Literary and Artistic Works (as amended on
September 28, 1979), the Rome Convention of 1961, the WIPO Copyright
Treaty of 1996, the WIPO Performances and Phonograms Treaty of 1996 and
the Universal Copyright Convention (as revised on July 24, 1971). These
rights and subject matter take effect in the relevant jurisdiction in
which the License terms are sought to be enforced according to the
corresponding provisions of the implementation of those treaty
provisions in the applicable national law. If the standard suite of
rights granted under applicable copyright law includes additional rights
not granted under this License, such additional rights are deemed to be
included in the License; this License is not intended to restrict the
license of any rights under applicable law.
․
․
Creative Commons Notice
․
Creative Commons is not a party to this License, and makes no warranty
whatsoever in connection with the Work. Creative Commons will not be
liable to You or any party on any legal theory for any damages
whatsoever, including without limitation any general, special,
incidental or consequential damages arising in connection to this
license. Notwithstanding the foregoing two (2) sentences, if Creative
Commons has expressly identified itself as the Licensor hereunder, it
shall have all rights and obligations of Licensor.
․
Except for the limited purpose of indicating to the public that the Work
is licensed under the CCPL, Creative Commons does not authorize the use
by either party of the trademark "Creative Commons" or any related
trademark or logo of Creative Commons without the prior written consent
of Creative Commons. Any permitted use will be in compliance with
Creative Commons' then-current trademark usage guidelines, as may be
published on its website or otherwise made available upon request from
time to time. For the avoidance of doubt, this trademark restriction
does not form part of the License.

Creative Commons Corporation ("Creative Commons") is not a law firm and

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:
    wiki.creativecommons.org/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

    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.

 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. 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.


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.

 b. ShareAlike.

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

      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.

      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.

    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.
