If the Retrocessionaire is unauthorized or unaccredited as a reinsurer in any
state where the Company is domiciled or licensed, thereby preventing the Company
from obtaining full statutory financial statement credit for reinsurance
provided pursuant to this Agreement, the Retrocessionaire shall establish

Retrocessionaire's option, to the extent necessary to permit the Company to
obtain full credit for such reinsurance. The Retrocessionaire shall take any
additional steps necessary to permit the Company to obtain full credit for
reinsurance, to the extent credit is not otherwise available under applicable
law.

                                Letters of Credit

In the event the Retrocessionaire establishes letter(s) of credit, the following
provisions shall apply:

The Company shall forward to the Retrocessionaire a statement of the
Retrocessionaire's Minimum Funding Requirement (the "Minimum Funding
Requirement") within thirty (30) days after the close of each calendar quarter.
The Minimum Funding Requirement shall be calculated as follows: the sum of (i)
seventy-five percent (75%) of unearned premium required to be maintained by the
Company in respect of the Policies for state statutory accounting purposes
("Unearned Premium Reserve"), plus (ii) unpaid loss reserves including reserves
for losses incurred but not reported otherwise required to be maintained by the
Company in respect of the Policies for state statutory accounting purposes, plus
(iii) any additional liabilities due and payable to the Company hereunder, less
(iv) the Ceding Commission Credit, and less (v) any liabilities due and payable

Unearned Premium Reserve attributable to Service Agreements issued prior to
October 1, 2001, plus (ii) fifteen percent (15%) of Unearned Premium Reserve
attributable to Service Agreements issued on or after October 1, 2001.

Upon receipt of this statement, Retrocessionaire shall promptly apply for and

                                                                     (Continued)
