                                         the amount of the required Security
                                         Deposit as of the statement date,
                                         Reinsurer shall within 5 days after
                                         receipt of the notice of such excess
                                         pay to Chubb Re the amount of such
                                         excess so that the total amount of the
                                         Security Deposit equals the statement
                                         amount.

                                         On January 1, 2012, regardless of
                                         whether Reinsurer has reacquired an A-
                                         rating from A.M. Best, that portion of
                                         the Security Deposit which exceeds
                                         positive difference (if any) of (a) the
                                         Reinsurer's Obligations minus (b) the
                                         amount in the Experience Account, will
                                         be returned to Reinsurer.
