            PLEASE TAKE FURTHER NOTICE that, if your claim arose prior to the

Section 4.04 of the Plan with regard to the determination of the reasonableness
of the amount of such fees and expenses. Notwithstanding the foregoing, to the
extent any Indenture Trustee provides services related to distributions pursuant
to the Plan, each Indenture Trustee shall be entitled to receive from Trenwick
America LLC, without further Court approval, reasonable compensation for such
services and reimbursement of reasonable expenses incurred in connection with
such services, with such payment made on terms as agreed to between such
Indenture Trustee and Trenwick America LLC; provided, however, that if a dispute
arises with respect to such compensation and expenses, such dispute will be
resolved by the Bankruptcy Court.

            PLEASE TAKE FURTHER NOTICE THAT, THE RECORD DATE FOR DETERMINING THE
HOLDERS OF ALLOWED CLAIMS ENTITLED TO RECEIVE DISTRIBUTIONS UNDER THE PLAN WILL
BE AUGUST 15, 2005. Any claim transfer that is not docketed by the Court on or
before August 15, 2005 will not be recognized for purposes of making
distributions under the Plan.
