4. Restrictions. |
project. |
|
|
|
|
The license granted in Section 3 above is expressly made subject to and limited by the following restrictions: |
|
|
|
|
|
|
|
|
1. You may distribute, publicly display, publicly perform, or publicly |
|
|
digitally perform the Work only under the terms of this License, and You |
|
|
must include a copy of, or the Uniform Resource Identifier for, this |
|
|
License with every copy or phonorecord of the Work You distribute, |
|
|
publicly display, publicly perform, or publicly digitally perform. You |
|
|
may not offer or impose any terms on the Work that alter or restrict the |
|
|
terms of this License or the recipients' exercise of the rights granted |
|
|
hereunder. You may not sublicense the Work. You must keep intact all |
|
|
notices that refer to this License and to the disclaimer of warranties. |
|
|
You may not distribute, publicly display, publicly perform, or publicly |
|
|
digitally perform the Work with any technological measures that control |
|
|
access or use of the Work in a manner inconsistent with the terms of this |
|
|
License Agreement. The above applies to the Work as incorporated in a |
|
|
Collective Work, but this does not require the Collective Work apart from |
|
|
the Work itself to be made subject to the terms of this License. If You |
|
|
create a Collective Work, upon notice from any Licensor You must, to the |
|
|
extent practicable, remove from the Collective Work any reference to such |
|
|
Licensor or the Original Author, as requested. If You create a |
|
|
Derivative Work, upon notice from any Licensor You must, to the extent |
|
|
practicable, remove from the Derivative Work any reference to such |
|
|
Licensor or the Original Author, as requested. |
|
|
2. You may distribute, publicly display, publicly perform, or publicly |
|
|
digitally perform a Derivative Work only under the terms of this License, |
|
|
and You must include a copy of, or the Uniform Resource Identifier for, |
|
|
this License with every copy or phonorecord of each Derivative Work You |
|
|
distribute, publicly display, publicly perform, or publicly digitally |
|
|
perform. You may not offer or impose any terms on the Derivative Works |
|
|
that alter or restrict the terms of this License or the recipients' |
|
|
exercise of the rights granted hereunder, and You must keep intact all |
|
|
notices that refer to this License and to the disclaimer of warranties. |
|
|
You may not distribute, publicly display, publicly perform, or publicly |
|
|
digitally perform the Derivative Work with any technological measures |
|
|
that control access or use of the Work in a manner inconsistent with the |
|
|
terms of this License Agreement. The above applies to the Derivative |
|
|
Work as incorporated in a Collective Work, but this does not require the |
|
|
Collective Work apart from the Derivative Work itself to be made subject |
|
|
to the terms of this License. |
|
|
3. If you distribute, publicly display, publicly perform, or publicly |
|
|
digitally perform the Work or any Derivative Works or Collective Works, |
|
|
You must keep intact all copyright notices for the Work and give the |
|
|
Original Author credit reasonable to the medium or means You are |
|
|
utilizing by conveying the name (or pseudonym if applicable) of the |
|
|
Original Author if supplied; the title of the Work if supplied; in the |
|
|
case of a Derivative Work, a credit identifying the use of the Work in |
|
|
the Derivative Work (e.g., "French translation of the Work by Original |
|
|
Author," or "Screenplay based on original Work by Original Author"). |
|
|
Such credit may be implemented in any reasonable manner; provided, |
|
|
however, that in the case of a Derivative Work or Collective Work, at a |
|
|
minimum such credit will appear where any other comparable authorship |
|
|
credit appears and in a manner at least as prominent as such other |
|
|
comparable authorship credit. |
|
|
|
|
|
|
|
|
5. Representations, Warranties and Disclaimer |
|
|
|
|
|
1. By offering the Work for public release under this License, Licensor |
|
|
represents and warrants that, to the best of Licensor's knowledge after |
|
|
reasonable inquiry: |
|
|
1. Licensor has secured all rights in the Work necessary to grant the |
|
|
license rights hereunder and to permit the lawful exercise of the |
|
|
rights granted hereunder without You having any obligation to pay |
|
|
any royalties, compulsory license fees, residuals or any other |
|
|
payments; |
|
|
2. The Work does not infringe the copyright, trademark, publicity |
|
|
rights, common law rights or any other right of any third party or |
|
|
constitute defamation, invasion of privacy or other tortious injury |
|
|
to any third party. |
|
|
2. EXCEPT AS EXPRESSLY STATED IN THIS LICENSE OR OTHERWISE AGREED IN WRITING |
|
|
OR REQUIRED BY APPLICABLE LAW, THE WORK IS LICENSED ON AN "AS IS" BASIS, |
|
|
WITHOUT WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED INCLUDING, |
|
|
WITHOUT LIMITATION, ANY WARRANTIES REGARDING THE CONTENTS OR ACCURACY OF |
|
|
THE WORK. |
|
|
|
|
|
|
|
|
6. Limitation on Liability. |
|
|
|
|
|
EXCEPT TO THE EXTENT REQUIRED BY APPLICABLE LAW, AND EXCEPT FOR DAMAGES ARISING |
|
|
FROM LIABILITY TO A THIRD PARTY RESULTING FROM BREACH OF THE WARRANTIES IN |
|
|
SECTION 5, 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 Derivative Works or Collective |
|
|
Works 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 |
|
|
|
|
|
1. Each time You distribute or publicly digitally perform the Work or a |
|
|
Collective Work, 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 digitally perform a Derivative Work, |
|
|
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 |

|
|
sentences, if Creative Commons has expressly identified itself as the Licensor |

hereunder, it shall have all rights and obligations of Licensor. |
