If any provision of this Agreement is held to be illegal, invalid, or unenforceable under present or future laws effective during the term of this Agreement, such provision will be fully severable and this Agreement will be construed and enforced as if such illegal, invalid, or unenforceable provision had never comprised a part of this Agreement, and the remaining provisions of this Agreement will remain in full force and effect.

Each of the Parties will be responsible for its own expenses, including legal and accounting fees of advisors, incurred in connection with the negotiation and preparation of this Agreement. If any action is brought to enforce or interpret the terms of this Agreement (including through arbitration), the prevailing Party will be entitled to reasonable legal fees, costs, and disbursements in addition to any other relief to which such Party may be entitled.

     8.10 Dispute Resolution.

     (a) STELKAST and MAKO will attempt to settle any claim or controversy arising out of this Agreement through consultation and negotiation in good faith and in a spirit of mutual cooperation.

     (b) In the event that, after reasonable consultation, but within 30 days, the Parties are unable to reach agreement, any claim or controversy shall be settled by arbitration administered by the American Arbitration Association under its then current Commercial Arbitration Rules, before a single arbitrator and judgment on any award rendered by or finding of the arbitrator may be entered in any court having jurisdiction thereof. The arbitrator shall have the authority to award actual money damages (with interest on unpaid amounts from the date due), temporary injunctive relief, and reasonable attorney’s fees and expenses, but the arbitrator shall not have the authority to award exemplary or punitive damages, and the Parties expressly waive any claimed right to such damages.
