                    Participation)  of the Company's  gross  primary  premium on
                    Covered  Business  for  such  Underwriting  Year  due to the

                    Company shall give the Reinsurer  prompt  written  notice of

                    "Ratio Improvement  Trigger" means that the  Risk-to-Capital
                    Ratio has become less than or equal to 23-to-1.
