The Licensor makes no + representation that any Source or Product does not or will not + infringe any patent, copyright, trade secret or other + proprietary right. The entire risk as to the use, quality, and + performance of any Source or Product shall be with You and not + the Licensor.

Any such permitted use + shall be factual and shall not be made so as to suggest any kind + of endorsement or implication of involvement by the Licensor or + its personnel. + + 8.3 CERN may publish updated versions and variants of this Licence + which it considers to be in the spirit of this version, but may + differ in detail to address new problems or concerns. New + versions will be published with a unique version number and a + variant identifier specifying the variant. If the Licensor has + specified that a given variant applies to the Covered Source + without specifying a version, You may treat that Covered Source + as being released under any version of the CERN-OHL with that + variant. If no variant is specified, the Covered Source shall be + treated as being released under CERN-OHL-S. The Licensor may + also specify that the Covered Source is subject to a specific + version of the CERN-OHL or any later version in which case You + may apply this or any later version of CERN-OHL with the same + variant identifier published by CERN. + + 8.4 This Licence shall terminate with immediate effect if You fail + to comply with any of its terms and conditions. + + 8.5 However, if You cease all breaches of this Licence, then Your + Licence from any Licensor is reinstated unless such Licensor has + terminated this Licence by giving You, while You remain in + breach, a notice specifying the breach and requiring You to cure + it within 30 days, and You have failed to come into compliance + in all material respects by the end of the 30 day period. Should + You repeat the breach after receipt of a cure notice and + subsequent reinstatement, this Licence will terminate + immediately and permanently. Section 6 shall continue to apply + after any termination. + + 8.6 This Licence shall not be enforceable except by a Licensor + acting as such, and third party beneficiary rights are + specifically excluded.
