**5. Additional Terms.** You may choose to offer, and to charge a fee for, warranty, support, indemnity or liability obligations and/or other rights consistent with the term of this Licence (“Additional Terms”) to any legitimate recipients of the Software and/or Derivatives. The terms on which you provide such Additional Terms are on your sole responsibility and you shall indemnify, defend and hold XMOS harmless against any claims asserted against XMOS.
**6. New Versions.** XMOS may publish revised and/or new versions of this Licence from time to time to accommodate changes to the Licence terms, new versions, updates and bug fixes of the Software.

IN NO EVENT SHALL XMOS BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN CONTRACT, WARRANTY, CIVIL TORT (INCLUDING NEGLIGENCE), PRODUCTS LIABILITY OR OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION WITH THE SOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE INCLUDING GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES EVEN IF SUCH PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES AND NOT WITHSTANDING THE FAILURE OF ESSENTIAL PURPOSE. IN SOME JURISDICTIONS PARTIES ARE UNABLE TO LIMIT LIABILTY IN THIS WAY, IF THIS APPLIES TO YOUR JURISDICTION THIS LIABILITY CLAUSE ABOVE MAY NOT APPLY. NOTWITHSTANDING THE ABOVE, IN NO EVENT SHALL XMOS’s TOTAL LIABILITY TO YOU FOR ALL DAMAGES, LOSS OR OTHERWISE EXCEED $50.
