limitation on liability set forth in Section 2.2) will be reduced when any insurance proceeds in respect thereof are actually received by Parent to the extent that Parent is not required to pay such proceeds over to any of the Partnership

determine whether such claim is timely made.

Mark, the Partnership Group shall not in any manner represent that it has any ownership in the Name and the Mark or

any suit or take any action on account of any such infringements or imitations without first obtaining the written consent of Parent to do so. The Partnership Group agrees to assist Parent to the extent necessary in the procurement of any
registration, extension or renewal for, or to protect any of Parent’s rights to the Mark.

the services at the termination or expiration of this License will result in immediate and irremediable damage to Parent and to the rights of any subsequent licensee of the Name and the Mark. The Partnership Group acknowledges and admits that there
is no adequate remedy at law for such failure to cease manufacture, sale or distribution, and the Partnership Group agrees that in the event of such failure Parent shall be entitled to equitable relief by way of temporary and permanent injunctions
and such other further relief as any court with jurisdiction may deem just and proper.
