    Cautionary Note Regarding Forward-Looking Statements

    The Private Securities Litigation Reform Act of 1995 provides a
"safe harbor" for forward-looking statements. This release or any
other written or oral statements made by or on behalf of the Company
may include forward-looking statements that reflect the Company's
current views with respect to future events and financial performance.
All statements other than statements of historical fact included in

We believe that these factors include but are not limited to
ineffectiveness or obsolescence of our business strategy due to
changes in current or future market conditions; increased competition
on the basis of pricing, capacity, coverage terms or other factors;
greater frequency or severity of claims and loss activity, including
as a result of natural or man-made catastrophic events, than our
underwriting, reserving or investment practices anticipate based on
historical experience or industry data; the effects of acts of
terrorism or war; developments in the world's financial and capital
markets that adversely affect the performance of our investments;
changes in regulations or laws applicable to us, our subsidiaries,
brokers or customers; acceptance of our products and services,

products; loss of the services of any of our executive officers or
other key personnel; the effects of mergers, acquisitions and
divestitures; changes in rating agency policies or practices; changes
in legal theories of liability under our insurance policies; changes
in accounting policies or practices; and changes in general economic
