each item. Ashworth/Nantz Promotion Agreement - ------------------- Notwithstanding the foregoing, upon the occurrence of repeated intentional failures to comply with the terms and conditions of this Agreement, which have been noticed in accordance with the terms hereof (regardless of whether such failures have been cured), the non-defaulting party may immediately terminate this Agreement upon written notice to the defaulting party without affording a further opportunity to cure. Should Nantz Communications or Nantz disagree with the Company as to the existence of a condition affording the Company the right to so terminate this Agreement, Nantz Communications or Nantz shall, within thirty (30) days following the receipt of any such notice of termination, submit the matter to arbitration pursuant to the provisions of this Agreement. The termination rights set forth in this section shall not constitute the exclusive remedy of the non-defaulting party hereunder, however, and if a default is made by either party hereunder, the other may resort to such other remedies as said party would have been entitled to if this section had been omitted from this Agreement. Termination under the provisions of this section shall be without prejudice to any rights or claims which the terminating party may otherwise have against the defaulting party. From and after the termination of the Term all of the rights of the Company to the use of the Endorsement shall cease absolutely and the Company shall not thereafter use or refer to the Endorsement in advertising or promotion in any manner whatsoever. The Company shall not advertise, promote, distribute or sell any item whatsoever in connection with the use of any name, figure, design, logo, trademark or trade name confusingly similar to or suggestive of the Endorsement following the termination of the Term. ASSIGNMENT This Agreement shall bind and inure to the benefit of the parties hereto and their respective successors and permitted assigns. Nantz Communications and Nantz acknowledge that the Services to be rendered by Nantz Communications and Nantz are unique and personal. Accordingly, except as otherwise expressly provided below, neither Nantz Communications nor Nantz shall assign any of their respective rights or delegate any of their respective duties or obligations under this Agreement without the written consent of the Company. Nothing herein shall prevent Nantz Communications from assigning the monetary benefits of this Agreement as it may so desire. Further, inasmuch as it is recognized that Nantz Communications is the representative of Nantz, Nantz Communications may at any time assign this Agreement to Nantz and, in such event, Nantz Communications shall have no further obligation or liability in connection herewith and Nantz Communications' position vis-a'-vis the Company in connection herewith shall be in all respects the same as if Nantz Communications had signed this Agreement as agent rather than as a principal from the beginning. The rights granted the Company hereunder shall be used only by it and shall not, without the prior written consent of Nantz Communications or Nantz, be transferred or assigned to any other. In the event of the merger or consolidation of the Company with any other entity, Nantz Communications shall have the right to terminate the Agreement by so notifying the Company in writing on or before sixty (60) days Ashworth/Nantz Promotion Agreement - ------------------- after Nantz Communications has received notice of such merger or consolidation if and only if, by virtue of such merger or consolidation Nantz Communications or Nantz would be in default under or violating any provisions of any agreement to which he or it is subject entered into prior to June 1, 1994. ARBITRATION Unless otherwise mutually agreed to in writing by the Company, Nantz Communications and Nantz, any controversy or claim arising out of or related to this Agreement, or the breach thereof, shall be settled by arbitration in accordance with the Rules of the American Arbitration Association or any successor. Each of the Company, on the one hand, and Nantz Communications and Nantz, on the other hand, shall select one arbitrator and the two so selected shall select a third. Failing the selection of an arbitrator by either party or by the two so selected, the claim or controversy shall be settled by the American Arbitration Association upon the application of either party. Judgment upon any award of a majority of the arbitrators filed in a court of competent jurisdiction shall be binding. MISCELLANEOUS 24. NOTICES.
