IN ANY CASE, HUMAN HEAD STUDIOS AND HUMAN HEAD STUDIOS' OFFICERS, EMPLOYEES, DIRECTORS, SHAREHOLDERS, REPRESENTATIVES, AGENTS, LICENSEES (EXCLUDING YOU), SUB-LICENSEES (EXCLUDING YOU), SUCCESSORS, AND ASSIGNS SHALL NOT BE LIABLE FOR LOSS OF DATA, LOSS OF PROFITS, LOST SAVINGS, SPECIAL, INCIDENTAL, CONSEQUENTIAL, INDIRECT OR PUNITIVE DAMAGES, OR ANY OTHER DAMAGES ARISING FROM ANY ALLEGED CLAIM FOR BREACH OF WARRANTY, BREACH OF CONTRACT, NEGLIGENCE, STRICT PRODUCT LIABILITY, OR OTHER LEGAL THEORY EVEN IF HUMAN HEAD STUDIOS OR ITS RESPECTIVE AGENT(S) HAVE BEEN ADVISED OF THE POSSIBILITY OF ANY SUCH DAMAGES, OR EVEN IF SUCH DAMAGES ARE FORESEEABLE, OR LIABLE FOR ANY CLAIM BY ANY OTHER PARTY.  Some jurisdictions do not allow the exclusion or limitation of incidental or consequential damages, so the above limitation or exclusion may not apply to you.  This Section shall survive the cancellation or termination of this Agreement.

If any provision is determined to be unenforceable by a court of competent jurisdiction, you agree to a modification of such provision to provide for enforcement of the provision's intent, to the extent permitted by applicable law.
