In no event shall the licences granted herein be construed as granting you, expressly or by implication, estoppels or otherwise, a licence to use any ARM technology except the CMSIS Deliverables.

  2. SUPPORT. ARM is not obligated to support the CMSIS Deliverables but may do so entirely at ARM’s discretion.

  3. NO WARRANTY. YOU AGREE THAT THE CMSIS DELIVERABLES ARE LICENSED “AS IS”, AND THAT ARM EXPRESSLY DISCLAIMS ALL REPRESENTATIONS, WARRANTIES, CONDITIONS OR OTHER TERMS, EXPRESS, IMPLIED OR STATUTORY, INCLUDING WITHOUT LIMITATION THE IMPLIED WARRANTIES OF NON-INFRINGEMENT, SATISFACTORY QUALITY, AND FITNESS FOR A PARTICULAR PURPOSE.

THE LIMITATIONS, EXCLUSIONS AND DISCLAIMERS IN THIS LICENCE SHALL APPLY TO THE MAXIMUM EXTENT ALLOWED BY APPLICABLE LAW.

  5. THIRD PARTY RIGHTS. The Separate Files are delivered subject to and your use is governed by their own separate licence agreements. This Licence does not apply to such Separate Files and they are not included in the term “CMSIS Deliverables” under this Licence. You agree to comply with all terms and conditions imposed on you in respect of such Separate Files including those identified in the Schedule (“Third Party Terms”).
    ARM HEREBY DISCLAIMS ANY AND ALL WARRANTIES EXPRESS OR IMPLIED FROM ANY THIRD PARTIES REGARDING ANY SEPARATE FILES, ANY THIRD PARTY MATERIALS INCLUDED IN THE SOFTWARE, ANY THIRD PARTY MATERIALS FROM WHICH THE SOFTWARE IS DERIVED (COLLECTIVELY “OTHER CODE”), AND THE USE OF ANY OR ALL THE OTHER CODE IN CONNECTION WITH THE SOFTWARE, INCLUDING (WITHOUT LIMITATION) ANY WARRANTIES OF SATISFACTORY QUALITY OR FITNESS FOR A PARTICULAR PURPOSE.
