The accompanying unaudited pro forma condensed combined income statements of White Mountains for the periods ended March 31, 1999, June 30, 1999 and December 31, 1998 present results for White Mountains as if the Sale and certain transactions and adjustments related to the Sale had occurred as of January 1, 1999, January 1, 1999, and January 1, 1998, respectively. The accompanying unaudited pro forma condensed combined balance sheet of White Mountains as of March 31, 1999 presents White Mountains' financial position as if the Sale had occurred as of March 31, 1999. The unaudited pro forma financial information does not purport to represent what White Mountains' financial position or results of operations actually would have been had the Sale in fact occurred as of the dates indicated, or to project White Mountains' financial position or results of operations for any future date or period. The pro forma adjustments are based on available information and certain assumptions that White Mountains currently believes are reasonable under the circumstances.

White Mountains' financial statements will reflect the actual effects of the Sale on the date such event occurred. Although the actual Sale results will differ, the unaudited pro forma financial information reflects management's best estimate based on currently available information. The pro forma adjustments contained herein assume that the Federal tax rate is 35%, the maximum Federal statutory rate for corporations and that the applicable state tax rate is approximately 6%.
