1. Definitions
--------------------------------------------------------------------------------
a. "Adaptation" means a work based upon the Work, or upon the Work and other
   pre-existing works, such as a translation, adaptation, derivative 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(g) 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 above) for the purposes of this
   License.
c. "Distribute" means to make available to the public the original and copies of
   the Work or Adaptation, as appropriate, through sale or other transfer of
   ownership.

   offer(s) the Work under the terms of this License.
f. "Original Author" means, in the case of a literary or artistic work, the
   individual, individuals, entity or entities who created the Work or if no
   individual or entity can be identified, the publisher; and in addition (i) in

   persons who act, sing, deliver, declaim, 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 performance or other sounds; and, (iii) in the case of
   broadcasts, the organization that transmits the broadcast.
g. "Work" means the literary and/or artistic work offered under the terms of
   this License including without limitation any production in the literary,
   scientific and artistic domain, whatever may be the mode or 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; a cinematographic
   work to which are assimilated works expressed by a process analogous to
   cinematography; a work of drawing, painting, architecture, sculpture,
   engraving or lithography; a photographic work to which are assimilated works
   expressed by a process analogous to photography; a work of applied art; an
   illustration, map, plan, sketch or three-dimensional work relative to
   geography, topography, 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.
h. "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.
i. "Publicly Perform" means to perform public recitations of the Work and to
   communicate to the public those public recitations, by any means or process,

   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.
j. "Reproduce" means to make copies of the Work by any means including without
   limitation by sound or visual recordings and the right of fixation and

================================================================================
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.
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, including but not limited to the rights described in Section 4(e).

================================================================================
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(d), 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(d), as requested.
b. You may Distribute or Publicly Perform an Adaptation only under: (i) the
   terms of 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-NonCommercial-ShareAlike
   3.0 US) ("Applicable License"). You must include a copy of, or the URI, for
   Applicable License with every copy of each Adaptation You Distribute or
   Publicly Perform. 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. 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. 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. You may not exercise any of the rights granted to You in Section 3 above in
   any manner that is primarily intended for or directed toward commercial
   advantage or private monetary compensation. The exchange of the Work for
   other copyrighted works by means of digital file-sharing or otherwise shall
   not be considered to be intended for or directed toward commercial advantage
   or private monetary compensation, provided there is no payment of any
   monetary compensation in con-nection with the exchange of copyrighted works.
d. 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 Section 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(d) 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.
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 reserves the exclusive 
        right to collect such royalties for any exercise by You of the rights 
        granted under this License if Your exercise of such rights is for a 
        purpose or use which is otherwise than noncommercial as permitted 
        under Section 4(c) and otherwise waives the right to collect royalties 
        through any statutory or compulsory licensing scheme; and,
   iii. Voluntary License Schemes. The Licensor reserves 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 that is for a purpose or use which is 
        otherwise than noncommercial as permitted under Section 4(c).
f. 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 AND TO THE FULLEST
EXTENT PERMITTED BY APPLICABLE LAW, 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,
MERCHANTABILITY, 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 THIS 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.
