This press release may contain may contain "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. All statements, other than statements of historical facts, included or referenced in this release which address activities, events or developments which White Mountains expects or anticipates will or may occur in the future are forward-looking statements. The words "will," "believe," "intend," "expect," "anticipate," "project," "estimate," "predict" and similar expressions are also intended to identify forward-looking statements. These forward-looking statements include, among others, statements with respect to White Mountains':

   *growth in book value per share or return on equity;
   *business strategy;
   *financial and operating targets or plans;
   *incurred losses and the adequacy of its loss and LAE reserves;
   *projections of revenues, income (or loss), earnings (or loss) per share,
    dividends, market share or other financial forecasts;
   *expansion and growth of its business and operations; and
   *future capital expenditures.

These statements are based on certain assumptions and analyses made by White Mountains in light of its experience and perception of historical trends, current conditions and expected future developments, as well as other factors believed to be appropriate in the circumstances. However, whether actual results and developments will conform with its expectations and predictions is subject to a number of risks and uncertainties that could cause actual results to differ materially from expectations, including:

   *the failure of White Mountains to complete any or all of its recently
    announced acquisitions or, if White Mountains completes any such
    acquisition, the failure of any or all of such completed acquisitions to
    add value or enhance White Mountains' business;
   *claims arising from catastrophic events, such as hurricanes,
    earthquakes, floods or terrorist attacks; the continued availability of
    capital and financing;
   *general economic, market or business conditions;
   *competitive forces, including the conduct of other property and casualty
    insurers and reinsurers;
   *changes in domestic or foreign laws or regulations applicable to White
    Mountains, its competitors or its clients;
   *an economic downturn or other economic conditions, such as changes in
    foreign currency exchange rates, adversely affecting its financial
    position;
   *loss reserves established subsequently proving to have been inadequate;
    and other factors, most of which are beyond White Mountains' control.

Consequently, all of the forward-looking statements made in this press release are qualified by these cautionary statements, and there can be no assurance that the actual results or developments anticipated by White Mountains will be realized or, even if substantially realized, that they will have the expected consequences to, or effects on, White Mountains or its business or operations. White Mountains assumes no obligation to update publicly any such forward-looking statements, whether as a result of new information, future events or otherwise.
