ENFORCEMENT AND INDEMNIFICATION. ------------------------------- In the event that any party hereto breaches any of the terms of this Agreement (the "Breaching Party"), the Breaching Party acknowledges and agrees that said breach will result in immediate and irreparable harm to the business and goodwill of any non-breaching party hereto (the "Non-Breaching Party") and that damages, if any, and remedies at law for such breach, will be inadequate and not determinable. The Non-Breaching Party, upon a breach of this Agreement by the Breaching Party, shall therefore be entitled to (a) subject to Sections 15 and 24 hereof, apply for and receive from any court of competent jurisdiction, equitable relief by way of temporary or permanent injunction to restrain any breach of this Agreement and for such further relief as such court may deem just and proper, at law or in equity; (b) in the event that the Non- Breaching Party shall prevail in enforcing any of its rights hereunder, the Non- Breaching Party's reasonable costs and expenses in enforcing such rights under this Agreement (including court costs and reasonable legal fees and expenses); and (c) be indemnified and held harmless by the Breaching Party from and against any and all manner of expenses, losses, claims and liabilities of any kind incurred by the Non-Breaching Party (including its Affiliates) in connection with such breach. 15. DISPUTE RESOLUTION. ------------------ 15.1. Provisional Remedies: The procedures specified in this Section 15 shall be the sole and exclusive procedures for the resolution of disputes between the parties arising out of or relating to this Agreement; provided, -------- however, that a party, without prejudice to these procedures, may seek a - ------- preliminary injunction or other provisional relief if, in its sole judgment, such action is deemed necessary to avoid irreparable damage or to preserve the status quo. During such action, the parties will continue to participate in good faith in the procedures specified in this Section 15. 15.2. Negotiations Between Executives: The parties will attempt in good faith to resolve any claim or controversy arising out of or relating to the execution, interpretation or performance of this Agreement (including the validity, scope and enforceability of the provisions contained in this Section 15) promptly by negotiations between their designated executives. 15.3. Arbitration: In the event that any dispute arising out of or relating to this Agreement or its breach, termination or validity has not been resolved after good faith negotiation pursuant to the procedures of Section 15.2, such dispute shall upon written notice by either party 15 to the other, be finally settled by arbitration administered by the Center for Public Resources in accordance with the provisions of its Commercial Arbitration Rules and the United Stated Federal Arbitration Act, as modified below: (a) The arbitration shall be heard by a panel of three (3) independent and impartial arbitrators, all of whom shall be selected from a list of neutral arbitrators supplied by the Center for Public Resources.

(b) The arbitration proceedings shall be conducted in Los Angeles County or Orange County in the State of California.

PROVISIONS CONTRARY TO LAW/SEVERABILITY. --------------------------------------- In performing this Agreement, the parties hereto shall comply with all applicable laws, whether domestic or foreign.

In the event any provision of this Agreement conflicts with any applicable law or is otherwise determined by an arbitrator or court having valid jurisdiction thereover to be unenforceable, the affected provision of this Agreement shall be deemed to have been modified to the extent necessary so as not to conflict with the applicable law or to be unenforceable or, if such modification is not possible, such provision shall be deemed to have been deleted herefrom, without affecting, impairing or invalidating the remaining provisions of this Agreement. 19.
