  9. * secondly, the election of a governing law, French law, with which
  10. it is conformant, both as regards the law of torts and
  11. intellectual property law, and the protection that it offers to
  12. both authors and holders of the economic rights over software.
  13. The authors of the CeCILL (for Ce[a] C[nrs] I[nria] L[ogiciel] L[ibre])
  14. license are:

  35. In this respect, the risks associated with loading, using, modifying
  36. and/or developing or reproducing the software by the user are brought to

  42. enabling the security of their systems and/or data to be ensured and,
  43. more generally, to use and operate it in the same conditions of

  45. provided it is not altered, and that no provisions are either added or
  46. removed herefrom.

  257. Article 9 - WARRANTY
  258. 9.1 The Licensee acknowledges that the scientific and technical

  281. 9.4 The Licensor does not either expressly or tacitly warrant that the
  282. Software does not infringe any third party intellectual property right
  283. relating to a patent, software or any other property right. Therefore,
  284. the Licensor disclaims any and all liability towards the Licensee
  285. arising out of any or all proceedings for infringement that may be
  286. instituted in respect of the use, modification and redistribution of the
  287. Software. Nevertheless, should such proceedings be instituted against
  288. the Licensee, the Licensor shall provide it with technical and legal
  289. assistance for its defense. Such technical and legal assistance shall be
  290. decided on a case-by-case basis between the relevant Licensor and the
  291. Licensee pursuant to a memorandum of understanding. The Licensor
  292. disclaims any and all liability as regards the Licensee's use of the

  300. remained ineffective.
  301. 10.2 A Licensee whose Agreement is terminated shall no longer be
  302. authorized to use, modify or distribute the Software. However, any
  303. licenses that it may have granted prior to termination of the Agreement
  304. shall remain valid subject to their having been granted in compliance
  305. with the terms and conditions hereof.
  306. Article 11 - MISCELLANEOUS
  307. 11.1 EXCUSABLE EVENTS
  308. Neither Party shall be liable for any or all delay, or failure to
  309. perform the Agreement, that may be attributable to an event of force

  318. invoke said provision(s) subsequently.

  320. whether written or oral, between the Parties and having the same

  326. 11.4 In the event that one or more of the provisions hereof were to
  327. conflict with a current or future applicable act or legislative text,
  328. said act or legislative text shall prevail, and the Parties shall make
  329. the necessary amendments so as to comply with said act or legislative
  330. text. All other provisions shall remain effective. Similarly, invalidity
