In the event there are any recoveries, salvages, or reimbursements recovered subsequent to a loss settlement, or in the event a verdict or judgment is reversed or reduced, the allocated loss adjustment expenses incurred in obtaining the recovery, salvage or reimbursement or in securing the reduction or reversal shall be divided between the Reassured and the Reinsurer in proportion to their share of the benefit therefrom, with the expenses incurred up to the time of the loss settlement or the original verdict or judgment being divided in proportion to the share of the Reassured and the Reinsurer in the original loss settlement or verdict or judgment. 5. The Reinsurer shall be subrogated, as respects any loss for which the Reinsurer shall actually pay or become liable, but only to the extent of the amount of payment by or the amount of liability to the Reinsurer, to all the rights of the Reassured against any person or other entity who may be legally responsible in damages for said loss.

ARTICLE XI LOSSES IN EXCESS OF POLICY LIMITS 1. The Reinsurer shall reinsure the Reassured, subject to the limit of this Treaty, for 50% of any loss in excess of the limit of its policy, such loss in excess of the limit having been incurred because of the failure by it to settle within the policy limit or by reason of alleged or actual negligence, fraud or bad faith in rejecting a offer of settlement, in the preparation of the defense or in the trial of any action against its insured or reassured or in the preparation or prosecution of an appeal consequent upon such action. 2. For the purposes of Paragraph 1. of this Article, the word "loss" shall mean any amounts for which the Reassured would have been contractually liable to pay had it not been for the limit of the policy. 3.

ARTICLE XII PREMIUM AND COMMISSION 1. A. The premium payable to the Reinsurer hereunder shall be calculated at the same gross rates and on the same basis as the premiums received by the Reassured on its original policies. B. The Reinsurer agrees to allow the Reassured a commission subject to a provisional rate of 20% on a sliding scale basis as follows: The provisional commission of 20% will be charged at a 75% loss ratio. The Reassured's commission will decrease .25% for each 1.0% increase in the loss ratio, to a minimum of 15% at a loss ratio of 95.0%. The Reassured's commission will increase .25% for each 1.0% decrease in the loss ratio, to a maximum of 25% at a 55% loss ratio. The initial commission adjustment period will be from January 1, 1997 to December 31, 1997. Thereafter, the commission adjustment period will be defined as each twelve consecutive calendar months during the term this Treaty remains in force. Commission adjustments will be computed at the end of the first consecutive fourteen month period. Thereafter, the commission adjustments will be computed annually, until all losses occurring during the respective commission adjustment period have been settled. C. The adjusted or final percentage of commission for any commission adjustment period shall be applied to the earned premiums hereunder for such period and the difference, if any, between the adjusted commission so determined and the provisional commission of 20.0% of written premiums for the period shall be paid by the debtor to the creditor. 6. D. The loss ratio for each commission adjustment period shall be determined by dividing losses (including losses in Excess of Policy Limits and Extra Contractual Obligations) and allocated loss adjustment expenses, incurred during the period by premiums earned during the period. E. The period from the inception hereof through December 31, 1997 shall constitute the first commission adjustment period hereunder. Each subsequent 12 month period shall constitute a further commission adjustment period hereunder. Adjustment period, the period from the end of the last complete commission adjustment period, or the inception of this Treaty if cancelled during the first commission adjustment period, to the date of cancellation, shall constitute a commission adjustment period hereunder.

If the statement shows that the Reinsurer's share of obligations exceeds the balance of credit as of the statement date, the Reinsurer shall, within thirty(30) days after receipt of notice of such excess, secure delivery to the Reassured of an amendment of the Letter of Credit increasing the amount of credit by the amount of such difference. If the statement shows, however, that the Reinsurer's share of obligations is less than the balance of credit as of the statement date, the Reassured shall, within thirty(30) days after receipt of written request from the Reinsurer, release such excess credit by agreeing to secure an amendment to the Letter of Credit reducing the amount of credit available by the amount of such excess credit. 6. The bank shall have no responsibility whatsoever in connection with the propriety of withdrawals made by the Reassured or the disposition of funds withdrawn, except to assure that withdrawals are made only upon the order of properly authorized representatives of the Reassured.
