               UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL
                                  STATEMENTS


The following unaudited pro forma condensed combined statements of income
for the nine months ended September 30, 1998 and the year ended December
31, 1997 and the unaudited pro forma condensed combined balance sheet as of
September 30, 1998 give effect to the acquisition of Sedgwick. The purchase
method of accounting has been applied to the transaction. The pro forma
statements of income assume the acquisition occurred on January 1, 1997 and
the pro forma balance sheet assumes the transaction occurred on September
30, 1998.

The unaudited pro forma statements of income do not include potential cost
savings that may be realized as a result of the acquisition or the effect
of a special charge that is expected to include, among other items, the
Registrant's cost (non-goodwill) related to severance arrangements, the
closing of existing facilities and the issuance of certain deferred stock
units. The Registrant has indicated that it anticipates ultimately
achieving gross pretax cost savings in the range of $200 million per year,
over a period of years. See "Information Concerning Forward-Looking
Statements".

The unaudited pro forma condensed combined financial statements have been
prepared by the Registrant based upon the assumptions disclosed in the
notes to the pro forma condensed combined financial statements and reflect
the Registrant's expectation that it will acquire 100% of Sedgwick's issued
share capital and issued convertible bonds. The unaudited pro forma
financial statements presented herein are shown for illustrative purposes
only and do not purport to be indicative of the results which would have
been reported if the transaction had occurred on the dates indicated or
which may occur in the future. The unaudited pro forma condensed combined
financial statements should be read in conjunction with the consolidated
financial statements and notes thereto included in the Registrant's
Quarterly Report on Form 10-Q for the nine months ended September 30, 1998
and Annual Report on Form 10-K for the year ended December 31, 1997 and the
Sedgwick financial statements included in Exhibits 99.1 and 99.2 of this
Form 8-K.

         NOTES TO PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS



A description of the adjustments reflected in the pro forma condensed
combined financial statements follows:

(a)   Certain amounts included in the Sedgwick consolidated statements of
      income (interest income, interest expense, equity in income of
      affiliates and minority interest in income of subsidiaries) have been
      reclassified to conform with the Registrant's financial statement
      presentation and have been presented in accordance with U.S.
      Generally Accepted Accounting Principles. (See note 32 of the
      financial statements in Exhibit 99.1 and Additional information for
      US investors in Exhibit 99.2) Results for the year ended December 31,
      1997 and the nine months ended September 30, 1998 have been
      translated at(pound) = US$1.64 and(pound) = US$1.65, respectively.

(b)   To reflect the incremental estimated annual goodwill amortization
      charge associated with the acquisition of Sedgwick (the
      "acquisition"). Goodwill is estimated at $1.45 billion and is being
      amortized over a forty-year period.

(c)   To record the additional annual interest expense associated with the
      estimated $1.586 billion of incremental debt that is expected to be
      incurred by the Registrant as a result of the acquisition. The
      assumed interest rate of 6.31% represents the weighted average
      interest rate of the expected incremental debt based on prevailing
      rates. The actual interest rate may vary from the assumed rate. The
      annual effect on pretax income of a one-eighth percent variance in
      this rate is $2.0 million.

(d)   To record the tax effect of the pro forma adjustments related to the
      additional annual interest expense. The assumed tax rate of 35%
      represents the federal tax benefit on the estimated incremental
      interest expense. The Registrant does not anticipate any state and
      local tax benefit on this interest expense.

(e)   To reflect the issuance of $529 million (10 million shares) of the
      Registrant's $1 par value common stock representing the estimated
      portion of the acquisition cost to be financed through equity.

(f)   Certain amounts included in the Sedgwick consolidated balance sheet
      have been reclassified to conform with the Registrant's financial
      statement presentation. In particular, fiduciary cash and investments
      of $571 million have been offset against the related liabilities and
      presented in the liability section of the balance sheet. In addition,
      receivables and payables for uncollected premiums and claims are
      presented in footnote disclosure in the Registrant's financial
      statements. The balance sheet has been translated at(pound) =
      US$1.70.

(g)   The Registrant's management is in the preliminary stages of identifying
      the impact of purchase related matters, principally related to
      severance, duplicative real estate, and adjustments of asset and
      liability balances to fair values. The preliminary estimate of these
      purchase related matters of $600 million and the related income tax
      benefit of $210 million, which may differ from the final resolution
      of such items, are not included in the pro forma financial
      statements.

(h)   Represents the excess of the $2.115 billion acquisition consideration
      over the $665 million acquired net assets of Sedgwick. The
      Registrant's management is in the process of, but has not completed,
      identifying intangibles or fair values of assets acquired and
      liabilities assumed. Since there are no known adjustments at this
      time, the fair values of assets and liabilities are assumed to be the
      carrying values on the Sedgwick balance sheet and the excess of the
      acquisition consideration over the acquired net assets has been
      allocated to goodwill. The preliminary purchase price allocation to
      the underlying assets and liabilities of Sedgwick, including
      goodwill, is subject to further refinement as the Registrant's
      management continues to review the estimated fair values of the
      assets acquired and the liabilities assumed. The final purchase price
      allocation could be materially different from this preliminary
      allocation.

(i)   To reflect the incremental debt assumed to be incurred to finance
      $1.586 billion of the acquisition.

(j)   To record the elimination of $665 million of Sedgwick stockholders'
      equity.
