LICENSE MAY BE CONSIDERED TO BE A CONTRACT, THE LICENSOR GRANTS YOU THE
RIGHTS CONTAINED HERE IN CONSIDERATION OF YOUR ACCEPTANCE OF SUCH TERMS

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(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 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.
 d "Licensor" means the individual, individuals, entity or entities
   that offer(s) the Work under the terms of this License.
 e "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 the case of a performance the actors, singers,
   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.
 f "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.
 g "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.
 h "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.
 i "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 reproducing fixations of the Work, including storage of
   a protected performance or phonogram in digital form or other
   electronic medium.

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.
 f 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(b),
   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(b), as requested.
 b 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 (b) 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.
 c 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.

   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

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,

 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

        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.
