          NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS (continued)


Note 5 - Provisions for liabilities and charges

      In common with many companies involved in selling personal pension plans
in the UK, the Company's financial advisory business, Willis Corroon Financial
Planning Limited ("WCFP"), is required by the Financial Services Authority ("the
Regulator"), which regulates these matters, to review certain categories of
personal pension plans sold to individuals between 1988 and 1994. WCFP is
required to compensate those individuals who transferred from, opted out or did
not join, their employer-sponsored pension plan if the expected benefits from
their personal pension plan did not equal the benefits that would have been
available from their employer-sponsored pension plan. Whether compensation is
due to a particular individual, and the amount thereof, is dependent upon the
subsequent performance of the personal pension plan sold and the net present
value of the benefits that would have been available from the employer-sponsored
pension plan calculated using financial and demographic assumptions prescribed
by the Regulator.

      At June 30, 2003, the Company had provisions of $13.4 million relating to
this issue. Although the Company considers these provisions to be prudent, there
remains some uncertainty as to the ultimate exposure relating to the review.

      At June 30, 2003, the Company had provisions of $15.1 million for
discontinued operations that includes estimates for future costs of
administering the run-off of the Company's former UK underwriting operations.
Willis Faber (Underwriting Management) Limited ("WFUM"), a wholly-owned
subsidiary of the Company, provided underwriting agency and other services to
certain insurance companies including Sovereign Marine & General Insurance
Company Limited (in Scheme of Arrangement) ("Sovereign") (collectively, the
"stamp companies") and in 1991 ceased arranging new business on behalf of the
stamp companies. Willis Faber Limited has agreed with certain of the stamp
companies to fund certain costs of the run-off, subject to agreed guidelines as
to timing and amount. Although the Company expects the run-off to be conducted
in an orderly manner, it may ultimately prove to be a lengthy and expensive
process. The amounts to be funded under the run-off arrangements are currently
within the aggregate of the provisions made.

      The Company is subject to various actual and potential claims, lawsuits
and proceedings relating principally to alleged errors and omissions in
connection with the placement of insurance and reinsurance in the ordinary
course of business. Similar to other corporations, the Company is also subject
to a variety of other claims, including those relating to the Company's
employment practices. Some of those claims, lawsuits and proceedings seek
damages in amounts which could, if assessed, be significant.

      Most of the claims, lawsuits and proceedings arising in the ordinary
course of business are covered by professional indemnity or other appropriate
insurance. In respect of self-insured deductibles, the Company has established
provisions against these items which are believed to be adequate in the light of
current information and legal advice, and the Company adjusts such provisions
from time to time according to developments. On the basis of current
information, the Company does not expect that the outcome of the actual claims,
lawsuits and proceedings to which the Company is subject or potential claims,
lawsuits and proceedings, either individually or in the aggregate, will have a
material adverse effect on the Company's financial condition, results of
operations or liquidity.

Note 6 - Differences between accounting principles generally accepted in the
United Kingdom and the United States

      The unaudited condensed consolidated financial statements are prepared in
accordance with UK GAAP which differ in certain respects from US GAAP. Summaries
of the significant differences as they apply to the Company are set forth in
Note 30 of Notes to the Company's Consolidated Financial Statements for the year
ended December 31, 2002.

      The effect on net income/(loss), comprehensive income/(loss) and
shareholders' equity of applying the significant differences between UK GAAP and

Note 7 - Subsequent Event

      Following enactment of the UK Finance Act 2003 on July 10, 2003, stock
options exercised by UK employees on or after January 1, 2003 will give rise to
a corporate tax deduction based on the difference between the Willis share price
on the date of exercise and the option exercise price.

      Consequently, in the third quarter of 2003, a tax benefit will be
recognized based on the number of stock options exercised in the nine-month
period to September 30, 2003.

      Had the legislation been in force at June 30, 2003 a tax benefit of
approximately $28.0 million would have been recognized.

                      WILLIS GROUP LIMITED AND SUBSIDIARIES
                  OPERATING AND FINANCIAL REVIEW AND PROSPECTS

Summary

      Total revenues increased by $80.6 million (20%) to $491.6 million in the
second quarter of 2003 from $411.0 million in the second quarter of 2002.
Approximately 4% of this increase was attributable to the effect of foreign
currency exchange rate movements and approximately (2)% was attributable to the
effects of acquisitions and disposals. Adjusting for these items, total revenues
on an underlying basis were 18% higher in the second quarter of 2003 than in the
corresponding quarter of 2002. For the six months to June 30, 2003, total
revenues were $1,046.7 million, 21% higher than in the corresponding period of
2002. Approximately 5% of this increase was attributable to the effect of
foreign currency exchange rate movements and approximately (2)% was attributable
to the effects of acquisitions and disposals. Adjusting for these items, total
revenues on an underlying basis were 18% higher than in the corresponding period
of 2002. Of the 18% increase in our underlying revenues for the six months, 13%
was attributable to net new business, up from 10% in the corresponding period a
year ago, and 5% from higher premium rates.

      Operating income increased by $29.2 million (28%) to $133.0 million in the
second quarter of 2003 from $103.8 million in the second quarter of 2002. For
the six months, operating income was $322.9 million, an increase of $74.5
million (30%) compared to the corresponding period in 2002.

      Net income increased by $24.7 million (38%) to $89.3 million ($0.19 per
share) in the second quarter of 2003 from net income of $64.6 million ($0.13 per
share) in the second quarter of 2002. For the six months, net income was $220.1
million ($0.46 per share) compared with $157.7 million ($0.33 per share) a year
ago.

Revenues

      Commissions and fees increased by 20% to $472.6 million in the second
quarter of 2003 from $393.2 million in the second quarter of 2002 and interest
income earned of $19.0 million on fiduciary funds was $1.2 million (7%) higher
than in the second quarter 2002.

      Global: Revenues generated by our Global business increased by 24% to
$244.5 million in the second quarter of 2003 from $197.4 million in the second
quarter of 2002. Approximately 4% of this increase in revenues arose from the
effects of foreign currency exchange rate movements. The effect of acquisitions
and disposals was immaterial. Adjusting for these items, Global's revenues on an
underlying basis increased by 20%. Global's property and casualty, reinsurance
and specialties, including marine and aerospace, continued to grow through new
business wins across our global marketplace and higher premium rates.

      North America: Revenues generated by our North America business increased
by 9% to $171.9 million in the second quarter of 2003 from $158.0 million in the
second quarter of 2002. The disposal of the third-party administration units in
2002 impacted the increase in revenues by approximately (5)%. Adjusting for this
item, North America's revenues on an underlying basis increased by 14%
attributable to new business development and higher premium rates.

      International: Revenues generated by our International business increased
by 35% to $75.2 million in the second quarter of 2003 from $55.6 million in the
second quarter of 2002. Foreign currency exchange rate movements accounted for
approximately 14% of the reported increase in revenues, largely due to the
strengthening of the euro, and the effect of acquisitions and disposals
accounted for a further 3% of the reported increase in revenues. Adjusting for
these items, International's revenues on an underlying basis increased by 18%,
led by good performance in Continental Europe, Latin America and Eastern
Hemisphere, principally Australia.

Expenses

      Operating expenses increased by $51.4 million (17%) to $358.6 million in
the second quarter of 2003 from $307.2 million in the second quarter of 2002.
Foreign currency exchange rate movements accounted for approximately 3% of the
increase in operating expenses and approximately (2)% was attributable to the
effect of acquisitions and disposals. Adjusting for these items, operating
expenses grew by 16% in the second quarter of 2003 compared with the second
quarter of 2002. Much of the increase related to increased incentive
compensation due to positive results and the impact of hiring production and
sales executives. For the six months, operating expenses were 18% higher than a
year ago but 16% on a constant currency basis adjusting for acquisitions and
disposals. Approximately 5% of the reported increase in operating expenses was
attributable to foreign currency exchange rate movements and approximately (3)%
was attributable to the effect of acquisitions and disposals.

 Profit/(loss) on disposal/closure of operations

      During the second quarter of 2003, the Company disposed of the business of
its retail office in Salt Lake City and its shareholding in its associate Buck &
Willis Healthcare Limited. These disposals generated a profit on disposal of
$3.9 million which included a non-cash charge of $0.8 million representing the
write-off of goodwill. During the second quarter 2002, the Company disposed of
Willis Safety Solutions. The loss on disposal amounted to $11.8 million which
included a non-cash charge of $11.1 million, representing the write-off of
goodwill previously eliminated against reserves.

Associates

      Our share of income before tax of our associates was $1.7 million in the
second quarter of 2003, compared with $1.4 million in the corresponding period
of 2002. For the six months, our share of income before tax of our associates
was $17.1 million compared with $11.9 million a year ago. This increase was due
to improved performance of our associates, led by Gras Savoye.

                      WILLIS GROUP LIMITED AND SUBSIDIARIES
                  OPERATING AND FINANCIAL REVIEW AND PROSPECTS

Interest

      Interest income of $12.4 million in the second quarter of 2003 was $5.3
million lower than in the second quarter of 2002, reflecting lower principal
amounts of debt outstanding totaling $578.9 million at June 30, 2003 compared
with $676.8 million a year ago. Interest income represents interest receivable
on loans advanced to our indirect parent company Trinity Acquisition Limited.

      Interest expense of $11.9 million in the second quarter of 2003 was $5.0
million lower than in the second quarter of 2002, reflecting lower principal
amounts of debt outstanding totaling $490.0 million at June 30, 2003 compared
with $676.8 million a year ago. Interest expense represents interest payable on
long-term debt consisting of senior credit facilities and the 9% senior
subordinated notes due 2009.

Minority Interest

      Minority interest for the second quarter of 2003 was $0.6 million compared
with $0.3 million for the second quarter of 2002. For the six months, minority
interest was $3.5 million, a decrease of $3.2 million compared with $6.7 million
a year ago. The decrease in minority interest was largely due to the acquisition
of the remaining 22% minority interest in Willis GmbH and the purchase of an
additional 23% ownership in Willis Iberia, both with effect from January 1,
2003.

Income Taxes

      Income tax expense for the second quarter of 2003 amounted to $49.2
million, this gives an effective tax rate of 36%, compared to 28% for 2002 after
adjusting for the profit/(loss) on disposal (including goodwill written off).
Income tax expense for the six months ended June 2003 amounted to $121.3
million, giving an effective tax rate of 35%, compared to 33% for the
corresponding period of 2002 after adjusting for the profit/(loss) on disposal
(including goodwill written off).

      On July 10, 2003, the UK Finance Act 2003 became law, provisions of which
granted a statutory corporate tax deduction for the compensation cost
attributable to exercises of stock options by UK employees. With effect from
January 1, 2003, we will be able obtain a UK corporate tax deduction for the
difference between the Willis share price on the date of exercise of a stock
option and the option exercise price. Consequently, we will recognize a tax
benefit in the third quarter of 2003 based on the number of stock options
exercised in the nine-month period to September 30, 2003. Had the legislation
been in force at June 30, 2003, we would have recognized a tax benefit of
approximately $28.0 million.

Liquidity and Capital Resources

      Net cash inflow from operating activities increased by $26.6 million to
$475.6 million in the six months from $449.0 million in the corresponding period
of 2002. This increase was primarily due to improved operating results. A cash
dividend of $22.7 million was paid on April 14, 2003.

      During the six months ended June 30, 2003, we repaid $39.5 million of our
term loans ahead of the repayment schedule and repurchased $38.0 million of 9%
Senior Subordinated Notes.

      On January 1, 2003, we acquired the remaining 22% interest, in addition to
the 78% already owned, in Willis GmbH, Germany's third largest insurance broker.
On January 1, 2003, we also acquired an additional 23% holding in Willis Iberia
to add to the 54% already owned. The remaining 23% of Willis Iberia is owned by
our associate, Gras Savoye. On May 29, 2003, we acquired a further 20% holding
in Willis Italia to add to the 67% we already owned.

      We expect that internally generated funds will be sufficient to meet our
foreseeable operating cash requirements, capital expenditures and scheduled debt
repayments, the next of which is not due until 2005. In addition, we have an
undrawn $150.0 million revolving credit facility.

Differences between UK GAAP and US GAAP

      Net income for the second quarter of 2003 of $89.3 million and for the six
months of $220.1 million under UK GAAP, compared with net income of $89.5
million and $218.0 million, respectively under US GAAP.

      Other differences arise principally from the differing accounting
treatment for goodwill, forward foreign exchange contracts in respect of future
income, pensions and related deferred taxation. Details of the reconciling

meaning of Section 27A of the Securities Act of 1933, as amended, and Section
21E of the Securities Exchange Act of 1934, as amended, that state our
intentions, beliefs, expectations or predictions for the future. These
forward-looking statements are subject to certain risks and uncertainties that
could cause actual results to differ materially from historical results or those

environment and the actual cost of resolution of contingent liabilities.
Although we believe that the expectations reflected in forward-looking
