**ARBITRATION ENDORSEMENT**

The Board shall, within ninety (90) calendar days following the conclusion of the hearing, render its decision on the matter or matters in controversy in writing and shall cause a copy thereof to be served on all the parties thereto. In case the Board fails to reach a unanimous decision, the decision of the majority of the members of the Board shall be deemed to be the decision of the Board and the same shall be final and binding on the parties thereto. Such decision shall be a complete defense to any attempted appeal or litigation of such decision in the absence of fraud or collusion. Without limiting the foregoing, the parties waive any right to appeal to, and/or seek collateral review of the decision of the Board of Arbitration by, any court or other body to the fullest extent permitted by applicable law, including, without limitation, application or appeal under Sections 45 and 69 of the Act. Any order as to the costs of the arbitration shall be in the sole discretion of the Board, who may direct to whom and by whom and in what manner they shall be paid.

The Insurer and the Insured agree that in the event that claims for indemnity or contribution are asserted in any action or proceeding against the Insurer by any of the Insured's other insurers in any jurisdiction or forum other than that set forth in this Endorsement, the Insured will in good faith take all reasonable steps requested by the Insurer to assist the Insurer in obtaining a dismissal of these claims (other than on the merits) and will, without limitation, undertake to the court or other tribunal to reduce any judgment or award against such other insurers to the extent that the court or tribunal determines that the Insurer would have been liable to such insurers for indemnity or contribution pursuant to this Policy. The Insured shall be entitled to assert claims against the Insurer for coverage under this Policy, including, without limitation, for amounts by which the Insured reduced its judgment against such other insurers in respect of such claims for indemnity or contribution, in an arbitration between the Insurer and the Insured pursuant to this Endorsement, which arbitration may take place before, concurrently with and/or after the action or proceeding involving such other insurers; provided, however, that the Insurer in such arbitration in respect of such reduction of any judgment shall be entitled to raise any defenses under this Policy and any other defenses (other than jurisdictional defenses) as it would have been entitled to raise in the action or proceeding with such insurers (and no determination in any such action or proceeding involving such other insurers shall have collateral estoppel, res judicata or other issue preclusion or estoppel effect against the Insurer in such arbitration, irrespective of whether or not the Insurer remained a party to such action or proceeding)."
