Additional agreements + +While distributing the Work, You may choose to conclude an additional agreement, +defining obligations or services consistent with this Licence. However, if +accepting obligations, You may act only on your own behalf and on your sole +responsibility, not on behalf of the original Licensor or any other Contributor, +and only if You agree to indemnify, defend, and hold each Contributor harmless +for any liability incurred by, or claims asserted against such Contributor by +the fact You have accepted any warranty or additional liability. + +10. Acceptance of the Licence + +The provisions of this Licence can be accepted by clicking on an icon ‘I agree’ +placed under the bottom of a window displaying the text of this Licence or by +affirming consent in any other similar way, in accordance with the rules of +applicable law.

Information to the public + +In case of any Distribution or Communication of the Work by means of electronic +communication by You (for example, by offering to download the Work from a +remote location) the distribution channel or media (for example, a website) must +at least provide to the public the information requested by the applicable law +regarding the Licensor, the Licence and the way it may be accessible, concluded, +stored and reproduced by the Licensee. + +12. Termination of the Licence + +The Licence and the rights granted hereunder will terminate automatically upon +any breach by the Licensee of the terms of the Licence. + +Such a termination will not terminate the licences of any person who has +received the Work from the Licensee under the Licence, provided such persons +remain in full compliance with the Licence. + +13. Miscellaneous + +Without prejudice of Article 9 above, the Licence represents the complete +agreement between the Parties as to the Work. + +If any provision of the Licence is invalid or unenforceable under applicable +law, this will not affect the validity or enforceability of the Licence as a +whole.
