5. All settlements of account under the Trust Agreement between the Company and Reinsurer shall be made in cash or its equivalent.

6. The Reinsurer and the Company agree that the assets in the Trust Account may be withdrawn by the Company at any time, notwithstanding any other provisions in the Agreement, provided such assets are applied and utilized by the Company or any successor of the Company by operation of law, including, without limitation, any liquidator, rehabilitator, receiver or conservator of the Company, without diminution because of the insolvency of the Company or the Reinsurer, only for the following purposes:

In the event that the Reinsurer seeks the Company’s approval hereunder, the Company shall not unreasonably or arbitrarily withhold its approval.

8. In the event that the Company withdraws assets from the Trust Account for the purposes set forth in Paragraph (6)(i) above in excess of actual amounts required to meet the Reinsurer’s Obligations to the Company (less the balance of credit available under any Letter(s) of Credit), or in excess of amounts determined to be due and under Paragraph (6)(iii) above, the Company will return such excess to the Reinsurer.

9. The Company will prepare and forward at annual intervals or more frequently as determined by the Company, but not more frequently than quarterly to the Reinsurer a statement for the purposes of this Article, showing the Reinsurer’s share of Obligations as set forth above. If the Reinsurer’s share thereof exceeds the then existing balance of the security provided, the Reinsurer will, within fifteen (15) days of receipt of the Company’s statement, but never later than December 31 of any year, increase the amount of the letter of credit, or Trust Account to the required amount of the Reinsurer’s share of Obligations set forth in the Company’s statement, but never later than December 31 of any year.

F. The Reinsurer will take any other reasonable steps that may be required for the Company to take full credit on its statutory financial statements for the reinsurance provided by this Agreement.

ARTICLE 13 - ERRORS AND OMISSIONS

Inadvertent delays, errors or omissions made by the Company in connection with this Agreement shall not relieve the Reinsurer from any liability which would have attached had such delay, error or omission not occurred, provided always that such delay, error or omission shall be rectified as soon as possible after discovery by the Company’s home office.

ARTICLE 14 - ACCESS TO RECORDS

The Company shall place at the disposal of the Reinsurer at all reasonable times, and the Reinsurer shall have the right to inspect through their designated representatives, during the Term of this Agreement and thereafter, all books, records and papers of the Company in connection with any reinsurance hereunder, or the subject matter hereof.

ARTICLE 15 - INSOLVENCY

A. In the event of insolvency and the appointment of a conservator, liquidator, or statutory successor of the Company, the portion of any risk or obligation assumed by the Reinsurer shall be payable to the conservator, liquidator, or statutory successor on the basis of claims allowed against the insolvent company by any court of Company having authority to allow such claims, without diminution because of that insolvency, or because the conservator, liquidator, or statutory successor has failed to pay all or a portion of any claims. Payments by the Reinsurer as set forth in this subdivision shall be made directly to the Company or to its conservator, liquidator, or statutory successor, except where, to the extent permitted by law, (a) this Agreement of reinsurance specifically provides another payee of such reinsurance in the event of the insolvency of the ceding insurer or (b) the Reinsurer with the consent of the direct insured(s) has assumed the Policy obligations of the Company as direct obligations of the Reinsurer to the payees under such Policies and in substitution for the obligations of the Company to such payees, or (c) except as provided by applicable law and regulation (such as subsection (a) of section 4118 of the New York Insurance laws) in the event of the insolvency of the Company.

B. In the event of the insolvency of the Company, the liquidator, receiver, conservator or statutory successor of the Company shall give written notice to the Reinsurer of the pendency of a claim against the insolvent Company on the Policy or Policies reinsured within a reasonable time after such claim is filed in the insolvency proceeding and during the pendency of such claim any Reinsurer may investigate such claim and interpose, at its own expense, in the proceeding where such claim is to be adjudicated any defense or defenses which it may deem available to the Company or its

liquidator, receiver, conservator or statutory successor. The expense thus incurred by the Reinsurer shall be chargeable subject to court approval against the insolvent Company as part of the expense of liquidation to the extent of a proportionate share of the benefit which may accrue to the Company solely as a result of the defense undertaken by the Reinsurer. Where two or more Reinsurers are involved in the same claim and a majority in interest elect to interpose defense to such claim, the expense shall be apportioned in accordance with the terms of this Agreement as though such expense had been incurred by the Company.

C. Neither a claimant, original insured nor the policyholder shall have any rights against the Reinsurer which are not specifically set forth in this Agreement, or in a specific agreement between the Reinsurer and the original insured or policyholder.

ARTICLE 16 - CONFIDENTIALITY

The parties acknowledge there may be portions of this Agreement, the Reinsurance Agreement submission or the marketing package that may contain confidential, proprietary information of the Company. The Reinsurer shall maintain the confidentiality of such information concerning the Company and its business and shall not disclose it to any third person without prior approval; provided, however, that the Reinsurer may be required and is permitted under this Agreement to disclose such information in answers to interrogatories, subpoenas or other legal/arbitration processes, or in response to requests by governmental and regulatory agencies. In addition, the Reinsurer may disclose such information to its accountants and to its outside legal counsel as may be necessary.

ARTICLE 17 - ARBITRATION

Any dispute or other matter in question between the Company and the Reinsurer arising out of, or relating to, the formation, interpretation, performance or breach of this Agreement, whether such dispute arises before or after termination of this Agreement, shall be settled by arbitration. Arbitration shall be initiated by the delivery of a written notice of demand for arbitration by one party to the other within a reasonable time after the dispute has arisen.

If more than one reinsurer is involved in the same dispute, all such reinsurers shall constitute and act as one party for the purposes of this Article, provided, however, that nothing herein shall impair the rights of such reinsurers to assert several, rather than joint, defenses or claims, nor be construed as changing the liability of the reinsurers under the terms of this Agreement from several to joint.

Each party shall appoint an individual as arbitrator and the two so appointed shall then appoint a third arbitrator. If either party refuses or neglects to appoint an arbitrator within 60 (sixty) days, the other party may appoint the second arbitrator. If the two arbitrators do not agree on a third arbitrator within 60 (sixty) days of their appointment, either party may petition the American Arbitration Association to appoint a third arbitrator. The arbitrators shall be active or former officers of insurance or reinsurance companies or Lloyd’s Underwriters; the arbitrators shall not have a personal or financial interest in the result of the arbitration.

The arbitration hearings shall be held in New York, New York. Each party shall submit its case to the arbitrators within 60 (sixty) days of the selection of the third arbitrator or within such longer period as may be agreed by the arbitrators. The arbitrators shall not be obliged to follow judicial formalities or the rules of evidence except to the extent required by governing law, that is, the state law of the situs of the arbitration as herein agreed; they shall make their decisions according to the practice of the reinsurance business. The decision rendered by a majority of the arbitrators shall be final and binding on both parties. Such decision shall be a condition precedent to any right of legal action arising out of the arbitrated dispute which either party may have against the other. Judgment upon the award rendered may be entered in any court having jurisdiction thereof.

Each party shall pay the fee and expenses of its own arbitrator and one-half of the fee and expenses of the third arbitrator. All other expenses of the arbitration shall be equally divided between the parties.

Except as provided above, arbitration shall be based, insofar as applicable, upon the procedures of the American Arbitration Association.

ARTICLE 18 - SERVICE OF SUIT

(This Article only applies to reinsurers domiciled outside the United States and/or unauthorized in any state, territory or district of the United States having jurisdiction over the Company.)

It is agreed that in the event of the failure of the Reinsurer hereon to pay any amount claimed to be due hereunder, the Reinsurer hereon, at the request of the Company, shall submit to the jurisdiction of a court of competent jurisdiction within the United States. Nothing in this Article constitutes or should be understood to constitute a waiver of the Reinsurer’s right to commence an action in any court of competent jurisdiction in the United States, to remove an action to a United States District Court, or to seek a transfer of a case to another court as permitted by the laws of the United States or of any state in the United States. It is further agreed that service of process in such suit may be made upon Mendes and Mount, 000 Xxxxxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx 00000-0000, and that in any suit instituted, the Reinsurer shall abide by the final decision of such court or of any Appellate Court in the event of an appeal.

Further, pursuant to any statute of any state, territory or district of the United States which makes provision therefor, the Reinsurer hereon hereby designates the Superintendent, Commissioner or Director of Insurance or other officer specified for that purpose in the statute, or his successor or successors in office, as their true and lawful attorney upon whom may be served any lawful process in any action, suit or proceeding instituted by or on behalf of the Company or any beneficiary hereunder arising out of this Agreement of reinsurance, and hereby designates the above-named as the person to whom the said officer is authorized to mail such process or a true copy thereof.

ARTICLE 19 - GOVERNING LAW

This Agreement shall be governed as to performance, administration and interpretation by the laws of the State of New York, exclusive of that state’s rules with respect to conflicts of laws, except as to rules with respect to credit for reinsurance in which case the rules of all applicable states shall apply.

ARTICLE 20 - MISCELLANEOUS
