License

BY EXERCISING ANY RIGHTS TO THE WORK PROVIDED HERE, YOU ACCEPT AND AGREE TO BE BOUND BY THE TERMS OF THIS LICENSE. TO THE EXTENT THIS LICENSE MAY BE CONSIDERED TO BE A CONTRACT, THE LICENSOR GRANTS YOU THE RIGHTS CONTAINED HERE IN CONSIDERATION OF YOUR ACCEPTANCE OF SUCH TERMS AND CONDITIONS.

1.
Definitions

1. "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.


2. "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.


3. "Creative Commons Compatible
   License" means a license that is listed at target="_blank"
   href="http://creativecommons.org/compatiblelicenses">http://creativecommons.org/compatiblelicenses
   that has been approved by Creative Commons as being essentially
   equivalent to this License, including, at a minimum, because that
   license: (i) contains terms that have the same purpose, meaning and
   effect as the License Elements of this License; and, (ii) explicitly
   permits the relicensing of 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.

   musicians, dancers, and other 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.


8. "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

   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

9. "You" means an individual or
   entity exercising rights under this License who has not previously

   received express permission from the Licensor to exercise rights under

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:

1. to Reproduce the
   Work, to incorporate the Work into one or more Collections, and to
   Reproduce the Work as incorporated in the Collections;


2. 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.";
3. to Distribute and Publicly Perform the
   Work including as incorporated in Collections; and,


4. to Distribute and Publicly Perform Adaptations.



5. For the avoidance of doubt:
    

6. 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;
7. 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,
8. 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:

1. 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.
2. 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.
3. 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.
4. 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

1. 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.
2. 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

type="a">
1. 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.
2. 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.
3. 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.
4. 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.
5. 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.


6. 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.
