Item 5. - Other Events

      On November 13, 2002 Trenwick Group Ltd. ("Trenwick"), and its
subsidiaries Trenwick America Corporation, Trenwick Holdings Limited and LaSalle
Re Holdings Limited, entered into a Forbearance Agreement, dated as of November
11, 2002 (the "Forbearance Agreement"), with certain lending institutions party
to the Credit Agreement, dated as of November 24, 1999 and amended and restated
as of September 27, 2000, and JP Morgan Chase Bank, as Administrative Agent. In
the Forbearance Agreement, the letter of credit providers agreed to refrain from
enforcing their rights or remedies under the Credit Agreement until November 22,
2002, or earlier if there is another default under the Credit Agreement or the
Forbearance Agreement, a third party exercises any right of action against
Trenwick for a debt in excess of $5,000 or other material obligation or Trenwick
takes an action which the letter of credit providers reasonably consider to be
materially adverse to their interests. In consideration for the forbearance of
the letter of credit providers, Trenwick agreed, among other things, to refrain
from making certain payments or distributions and to facilitate a meeting of the
letter of credit providers and Lloyd's.

      On November 14, 2002, Trenwick issued a press release announcing the
forbearance agreement. A copy of the press release is filed herewith as Exhibit
99.2 and is incorporated by reference herein.
