INFORMATION CONCERNING FORWARD-LOOKING STATEMENTS

Marsh & McLennan Companies, Inc. and its subsidiaries ("MMC") and their representatives may from time to time make verbal or written statements (including certain statements contained in this report and other MMC filings with the Securities and Exchange Commission and in our reports to stockholders) relating to future results, which are forward-looking statements as that term is defined in the Private Securities Litigation Reform Act of 1995. Such statements may include, without limitation, discussions concerning revenues, expenses, earnings, cash flow, capital structure, pension funding, financial losses and expected insurance recoveries resulting from the September 11, 2001 attack on the World Trade Center in New York City, as well as market and industry conditions, premium rates, financial markets, interest rates, foreign exchange rates, contingencies and matters relating to MMC's operations and income taxes. Such forward-looking statements are based on available current market and industry materials, experts' reports and opinions and long-term trends, as well as management's expectations concerning future events impacting MMC. Forward-looking statements by their very nature involve risks and uncertainties. Factors that may cause actual results to differ materially from those contemplated by any forward-looking statements contained or incorporated or referred to herein include, in the case of MMC's risk and insurance services and consulting businesses, the amount of actual insurance recoveries and financial losses from the September 11 attack on the World Trade Center, or other adverse consequences from that incident. Other factors that should be considered in the case of MMC's risk and insurance services business are changes in competitive conditions, movements in premium rate levels, the continuation of difficult conditions for the transfer of commercial risk and other changes in the global property and casualty insurance markets, the impact of terrorist attacks, natural catastrophes, and mergers between client organizations, including insurance and reinsurance companies insolvencies. Factors to be considered in the case of MMC's investment management business include changes in worldwide and national equity and fixed income markets, actual and relative investment performance, the level of sales and redemptions, and the ability to maintain investment management and administrative fees at appropriate levels; and with respect to all of MMC's activities, changes in general worldwide and national economic conditions, changes in the value of investments made in individual companies and investment funds, fluctuations in foreign currencies, actions of competitors or regulators, changes in interest rates or in the ability to access financial markets, developments relating to claims, lawsuits and contingencies, prospective and retrospective changes in the tax or accounting treatment of MMC's operations and the impact of tax and other legislation and regulation in the jurisdictions in which MMC operates.

Forward-looking statements speak only as of the date on which they are made, and MMC undertakes no obligation to update any forward-looking statement to reflect events or circumstances after the date on which it is made or to reflect the occurrence of unanticipated events.

MMC is committed to providing timely and materially accurate information to the investing public, consistent with our legal and regulatory obligations. To that end, MMC and its operating companies use their websites to convey meaningful information about their businesses, including the anticipated release of quarterly financial results, and the posting of updates of assets under management at Putnam. Monthly updates of total assets under management at Putnam will be posted to the MMC website on the first business day following the end of each month, except at the end of March, June, September and December, when such information will be released with MMC's quarterly earnings announcement. Putnam posts mutual fund and performance data to its website regularly. Assets for most Putnam retail mutual funds are posted approximately two weeks after each month-end. Mutual fund net asset value (NAV) is posted daily. Historical performance and Lipper rankings are also provided. Investors can link to MMC and its operating company websites through www.mmc.com.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)

1. Nature of Operations

MMC, a professional services firm, is organized based on the different services that it offers. Under this organization structure, MMC operates in three principal business segments: risk and insurance services, investment management and consulting. The risk and insurance services segment provides risk management and insurance broking, reinsurance broking and insurance program management services for businesses, public entities, insurance companies, associations, professional services organizations and private clients. It also provides services principally in connection with originating, structuring and managing insurance, financial services and other industry-focused investments. The investment management segment primarily provides securities investment advisory and management services and administrative services for a group of publicly held investment companies and institutional accounts. The consulting segment provides advice and services to the managements of organizations primarily in the areas of retirement services, human capital, health care and group benefit programs, management consulting, organizational change and organizational design, economic consulting and corporate identity.

2. Principles of Consolidation

The consolidated financial statements included herein have been prepared by MMC pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America, have been omitted pursuant to such rules and regulations, although MMC believes that the disclosures are adequate to make the information presented not misleading. These consolidated financial statements should be read in conjunction with the financial statements and the notes thereto included in MMC's latest Annual Report on Form 10-K.

The financial information contained herein reflects all adjustments which are, in the opinion of management, necessary for a fair presentation of the results of operations for the six-month periods ended June 30, 2003 and 2002. Certain reclassifications have been made to the prior year amounts to conform to the current year presentation.

The caption "Investment income (loss)" in the consolidated statements of income comprises realized and unrealized gains and losses from investments recognized in income. It includes other than temporary declines in the value of available for sale securities, the change in value of trading securities and the change in value of MMC's holdings in certain private equity funds. MMC's investments may include seed shares for mutual funds, direct investments in insurance, consulting or investment management companies and investments in private equity funds.

3. Fiduciary Assets and Liabilities

In its capacity as an insurance broker or agent, MMC collects premiums from insureds and, after deducting its commissions, remits the premiums to the

7

respective insurance underwriters. MMC also collects claims or refunds from underwriters on behalf of insureds. Unremitted insurance premiums and claims are held in a fiduciary capacity. Interest income on these fiduciary funds, included in service revenue, amounted to $61 million and $56 million for the six-month periods ended June 30, 2003 and 2002, respectively. Since fiduciary assets are not available for corporate use, they are shown in the balance sheet as an offset to fiduciary liabilities.

Net uncollected premiums and claims and the related payables amounted to $12.0 billion at June 30, 2003 and $11.7 billion at December 31, 2002, respectively. MMC is not a principal to the contracts under which the right to receive premiums or the right to receive reimbursement of insured losses arises. Net uncollected premiums and claims and the related payables are, therefore, not assets and liabilities of MMC and are not included in the accompanying Consolidated Balance Sheets.

4. Per Share Data

Basic net income per share is calculated by dividing net income by the weighted average number of shares of MMC's common stock outstanding. Diluted net income per share is calculated by reducing net income for the potential minority interest associated with unvested shares granted under the Putnam Equity Partnership Plan and adding back dividend equivalent expense related to common stock equivalents. This result is then divided by the weighted average common shares outstanding, which have been adjusted for the dilutive effect of potentially issuable common shares.

The following reconciles net income to net income for diluted earnings per share and basic weighted average common shares outstanding to diluted weighted average common shares outstanding for the three- and six-month periods ended June 30, 2003 and 2002.

The goodwill balance at June 30, 2003 and December 31, 2002 includes approximately $121 million of equity method goodwill.

Amortized intangible assets consist primarily of the cost of client lists and client relationships acquired and the rights to future revenue streams from certain existing private equity funds. MMC has no intangible assets with indefinite lives. The gross carrying amount and accumulated amortization by major intangible asset class is as follows:

9. Stock Benefit Plans

MMC has stock-based benefit plans under which employees are awarded grants of restricted stock, stock options and other forms of awards. As provided under SFAS No. 123, "Accounting for Stock-Based Compensation," ("SFAS 123")

10

MMC has elected to continue to account for stock-based compensation in accordance with Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees" ("APB 25") and has provided the required additional pro forma disclosures.

Pro Forma Information: In accordance with the intrinsic value method allowed by APB 25, no compensation cost has been recognized in the Consolidated Statements of Income for MMC's stock option and stock purchase plans and the stock options awarded under the Putnam Investments Equity Partnership Plan. If compensation cost for MMC's stock-based compensation plans had been determined consistent with the fair value method prescribed by SFAS No. 123, MMC's net income and net income per share for the three- and six-month periods ended June 30, 2003 and 2002 would have been reduced to the pro forma amounts indicated in the table below.

----------------------------------------------------------------------------------------------------------------------

The pro forma information above includes the cost of stock options issued under MMC incentive and stock award plans and the Putnam Investments Equity Partnership Plan and stock issued under MMC stock purchase plans. MMC stock purchase plans allow eligible employees to purchase MMC shares at prices not less than 85% of the less of the fair market value of the stock at the beginning or end of the offering period. The stock purchase plans represent approximately 20% of the increment from applying the fair value method in 2003 and 2002.

The estimated fair value of options granted was calculated using the Black-Scholes option pricing valuation model. The weighted average assumptions used in the valuation models are evaluated and revised, as necessary, to reflect market conditions and experience.

10. Long-term Debt

In February 2003, MMC issued $250 million of 3.625% Senior Notes due 2008 and $250 million of 4.85% Senior Notes due 2013. The net proceeds from the notes were used to pay down commercial paper borrowings.

In January 2003, MMC terminated and settled interest rate swaps that had hedged the fair value of senior notes issued in 2002. The cumulative amount of previously recognized adjustments of the fair value of the hedged notes is being amortized over the remaining life of those notes in accordance

11

with SFAS No. 133. As a result, the effective interest rate over the remaining life of the notes, including the amortization of the fair value adjustments, is 4.0% for the $500 million Senior Notes due in 2007 (5.375% coupon rate) and 5.1% for the $250 million Senior Notes due in 2012 (6.25% coupon rate).

Commercial paper borrowings of $250 million and $750 million respectively, at June 30, 2003 and December 31, 2002, have been classified as long-term debt based on MMC's intent and ability to maintain or refinance these obligations on a long-term basis.

In July 2003, MMC issued $300 million of 5.875% Senior Notes due 2033.

11. Integration and Restructuring Costs

In 1999, as part of the 1998 combination with Sedgwick Group, plc ("Sedgwick") and the integration of Sedgwick, MMC adopted a plan to reduce staff and consolidate duplicative offices. The estimated cost of this plan relating to employees and offices of Sedgwick ("1999 Sedgwick Plan") amounted to $285 million and was included in the cost of the acquisition. Merger-related costs for employees and offices of MMC ("1999 MMC Plan") amounted to $266 million and were recorded as part of a 1999 special charge.

In the third quarter of 2001, as a result of weakening business conditions, which were exacerbated by the events of September 11, MMC adopted a plan to provide for staff reductions and office consolidations, primarily in the consulting segment ("2001 Plan"). The charge of $61 million related to this Plan is comprised of $44 million for severance and related benefits affecting 750 people and $17 million for future rent under non-cancelable leases.

The utilization of these charges is summarized as follows:

------------------------------------------------------------------------------------------------------------

12. Common Stock

In 2003, MMC repurchased shares of its common stock for treasury as well as to meet requirements for issuance of shares for its various stock compensation and benefit programs. During the six-month period ended June 30, 2003, MMC repurchased 11.5 million shares for total consideration of $503 million.

MMC repurchases shares subject to market conditions, including from time to time pursuant to the terms of a 10b5-1 plan. A 10b5-1 plan allows a company to purchase shares during a blackout period, provided the company communicates its share purchase instructions to the broker prior to the blackout period, pursuant to a written plan that may not be changed. Approximately 1.8 million shares of the repurchases discussed above were made under the 10b5-1 plan.

13. Claims, Lawsuits and Other Contingencies

MMC and its subsidiaries are subject to various claims, lawsuits and proceedings consisting principally of alleged errors and omissions in connection with the placement of insurance or reinsurance and in rendering

13

investment and consulting services. Some of these matters seek damages, including punitive damages, in amounts that could, if assessed, be significant. Insurance coverage applicable to such matters includes elements of both risk retention and risk transfer.

As part of the combination with Sedgwick, MMC acquired River Thames Insurance Company Limited ("River Thames"), an insurance underwriting business that was already in run-off, which was sold in 2001. Sedgwick guaranteed payment of claims on certain policies underwritten through the Institute of London Underwriters by River Thames ("ILU Guarantee"). The policies covered by the ILU Guarantee are reinsured up to (pound)40 million by a related party of River Thames. Payment of claims under the reinsurance agreement is collateralized by segregated assets held in a trust. As of June 30, 2003, the reinsurance coverage exceeded the best estimate of the projected liability of the policies covered by the ILU Guarantee. To the extent River Thames or the reinsurer are unable to meet their obligations under those policies, a claimant may seek to recover from MMC under the guarantee. MMC does not expect any material net impact on its consolidated financial position or results of operations related to this guarantee.

Although the ultimate outcome of all matters referred to above cannot be ascertained and liabilities in indeterminate amounts may be imposed on MMC and its subsidiaries, on the basis of present information, it is the opinion of MMC's management that the disposition or ultimate determination of these claims, lawsuits, proceedings or guarantees will not have a material adverse effect on MMC's consolidated results of operations or its consolidated financial position.

14. Segment Information

MMC operates in three principal business segments based on the services provided. Segment performance is evaluated based on operating income, which is after deductions for directly related expenses and minority interest but before special charges. The accounting policies of the segments are the same as those used for the consolidated financial statements.

Selected information about MMC's operating segments for the six-month periods ended June 30, 2003 and 2002 follows:

15. New Accounting Pronouncements

In January 2003, the FASB issued Interpretation No. 46, "Consolidation of Variable Interest Entities" ("FIN 46"). FIN 46 interprets Accounting Research Bulletin No. 51, "Consolidated Financial Statements" and addresses consolidation by business enterprises qualifying as variable interest entities ("VIE"). FIN 46 defines a VIE as a corporation, partnership, trust or other legal structure used for business purposes that either (a) does not have equity investors with voting rights or (b) has equity investors that do not provide sufficient financial resources for the entity to support its activities. FIN 46 applies immediately to VIEs created after January 31, 2003 in which the company obtains an interest after that date. FIN 46 applies to the first fiscal year or interim period beginning after June 15, 2003 for VIEs in which MMC holds a variable interest that it acquired before February 1, 2003.

15

MMC through Putnam, manages $3.3 billion in the form of Collateralized Debt Obligations ("CDO") and Collateralized Bond Obligations ("CBO"). The CDOs and CBOs were created prior to January 31, 2003. Separate limited liability companies were established to issue the notes and to hold the underlying collateral, which consists of high-yield bonds and other securities. Putnam serves as the collateral manager for the CDOs and CBOs. The maximum loss exposure related to the CDOs and CBOs is limited to Putnam's investment totaling $4.0 million, reflected in Long-term investments in the Consolidated Balance Sheets at June 30, 2003. The implementation of FIN 46 will not have a significant impact on MMC's consolidated results of operations, financial position or cash flows. The FASB may issue future interpretive guidance to FIN 46.

Revenue growth on a constant currency basis in the risk and insurance services segment was 14% in the second quarter of 2003, reflecting strong growth across all geographies in both insurance and reinsurance broking. Consulting revenue on a constant currency basis grew 2% primarily resulting from a higher volume of business in retirement services and health care & group benefits. Revenue

decreased 15% in the investment management segment as average assets under management declined 14% from the second quarter of 2002. For the six months, revenue growth was 9%, 4% on a constant currency basis.

Operating expenses increased 11% in the second quarter of 2003 (5% on a constant currency basis) primarily due to increased compensation and benefit costs in the risk and insurance services segment partially offset by lower expenses in the investment management segment. Operating expenses also reflect an increase in costs for office space and insurance. For the six months, operating expenses increased 10%, 5% on a constant currency basis.

Revenue
Revenue for the risk and insurance services segment grew 17% over the second quarter of 2002 and on a constant currency basis grew 14%. The revenue growth reflects continued strong demand for Marsh's services as clients face new, expanding and more complex risks. The effect of higher premium rates and an increase in placement service activities also contributed to the increase in revenue. In the second quarter, constant currency revenues in risk management and insurance broking, which accounts for approximately three quarters of the risk and insurance services segment grew 13% with strong growth across all geographies. Constant currency revenue in reinsurance broking and services grew 24%. Related insurance services revenues increased 7% on a constant currency basis, with revenue increases in claims management and underwriting management partially offset by declines in the U.S. affinity business and MMC Capital. For the six months, revenue grew 19% over 2002 and 15% on a constant currency basis.

Pricing for commercial property risks has stabilized, however clients continue to face rate increases in most casualty lines, and restricted terms and conditions and coverage exclusions in all lines.

Expense
Risk and insurance services expenses increased 15% over the second quarter of 2002, 11% on a constant currency basis. Expense growth primarily reflects increased headcount due to higher volumes of business along with increased incentive compensation commensurate with the current operating environment. Operating expenses also reflect an increase in costs for office space and insurance. For the six months, operating expenses increased 17% over 2002, 13% on a constant currency basis.

Revenue
Putnam's revenue decreased 15% compared with the second quarter of 2002 reflecting a decline in the level of average assets under management on which fees are earned. Assets under management averaged $260 billion in the second quarter of 2003, a 14% decline from the $301 billion managed in the second quarter of 2002. Assets under management aggregated $267 billion at June 30, 2003 compared with $284 billion at June 30, 2002 and $251 billion at December 31, 2002. The change from December 31, 2002 results primarily from an increase in equity market levels partially offset by net redemptions of $4.3 billion, including reinvested dividends. Positive flows from institutional business were more than offset by net outflows in retail mutual funds. Assets under management at July 31, 2003 aggregated $267 billion.

Expense
Putnam's expenses decreased 10% in the second quarter of 2003 from the same period of 2002 primarily due to reductions in volume related expenses, including amortization of prepaid dealer commissions and incentive compensation.

Quarter-end and average assets under management are presented below:

The categories of mutual fund assets reflect style designations aligned with each fund's prospectus. All prior year amounts have been reclassified to conform with the current investment mandate for each product.

Assets under management and revenue levels are particularly affected by fluctuations in domestic and international stock and bond market prices, the composition of assets under management and by the level of investments and withdrawals for current and new fund shareholders and clients. U.S. equity markets, which declined in 2002 for the third consecutive year after several years of substantial growth prior to 2000, increased in the second quarter of 2003. Items affecting revenue also include, but are not limited to, actual and relative investment performance, service to clients, the development and marketing of new investment products, the relative attractiveness of the investment style under prevailing market conditions, changes in the investment patterns of clients and the ability to maintain investment management and administrative fees at appropriate levels. Revenue levels are sensitive to all of the factors above, but in particular, to significant changes in stock and bond market valuations.

Putnam provides individual and institutional investors with a broad range of both equity and fixed income investment products and services, invested domestically and globally, designed to meet varying investment objectives and which afford its clients the opportunity to allocate their investment resources among various investment products as changing worldwide economic and market conditions warrant.

At the end of the second quarter, assets held in equity securities represented 74% of assets under management, compared with 78% at June 30, 2002, while investments in fixed income products represented 26%, compared with 22% at June 30, 2002.

Revenue
Consulting revenue increased 16% over 2002 primarily due to the effect of foreign currency exchange rates, as well as acquisitions including Oliver, Wyman & Company ("OWC"), which is included in the management consulting practice. On a constant currency basis revenue increased 2%. Retirement services revenue, which represented approximately 50% of the consulting segment revenue, increased 3% on a constant currency basis and health care & group benefits consulting grew 6%. For the six months, revenue grew 14% over 2002, 3% on a constant currency basis.

Expense
Consulting expenses increased 17% over 2002 reflecting the impact of foreign exchange as well as the acquisition of OWC. As described in Note 7 to the financial statements, a portion of the OWC purchase consideration is contingent upon future employment. This amount has been accounted for as deferred compensation and is being recognized as compensation expense over four years. Expenses increased 2% on a constant currency basis over 2002. For the six months, expenses increased 15% over 2002, 3% on a constant currency basis.

Interest
Interest income earned on corporate funds amounted to $7 million in the second quarter of 2003, an increase of $3 million from the second quarter of 2002.

21

Interest expense of $46 million in 2003 increased from $38 million in the second quarter of 2002 primarily due to an increase in the average interest rates on outstanding debt in the second quarter of 2003. Since March 2002, MMC has improved liquidity and extended the average maturity of its debt through the issuance of $1.3 billion of long-term senior notes through June 30, 2003. The net proceeds from the notes were used to pay down outstanding commercial paper balances. The increase in the average interest rate results from the conversion of a significant portion of the company's debt from floating to fixed rates.

Income Taxes
MMC's consolidated effective tax rate was 34% of income before income taxes and minority interest in the second quarter of 2003 compared with 35.5% in the second quarter of 2002. As a result of the geographic mix of MMC's businesses, the effective tax rate for 2003 should remain at 34%.

Liquidity and Capital Resources
Operating Cash Flows
MMC anticipates that funds generated from operations will be sufficient to meet its foreseeable recurring operating cash requirements as well as to fund dividends, capital expenditures and scheduled repayments of long-term debt. MMC's ability to generate cash flow from operations is subject to the business risks inherent in each operating segment.

MMC generated $1.1 billion of cash from operations for the six-month period ended June 30, 2003 compared with $519 million for the same period in 2002. These amounts reflect the net income earned by MMC during those periods adjusted for non-cash charges and working capital changes. In 2003, MMC's tax payments decreased as compared to 2002. MMC's estimated tax payments related to the third quarter of 2001 were paid in the first quarter of 2002 due to the events of September 11, 2001 and the government's subsequent directives. In addition, current year tax payments reflect a refund of overpayment of prior year taxes. Other current assets at June 30, 2003 declined from the prior year end balance primarily due to lower deferred tax assets in the current period as well as a decrease in insurance recoveries receivable related to personal pension plan settlements in the United Kingdom.

MMC's cash and cash equivalents aggregated $618 million on June 30, 2003, an increase of $72 million from the end of 2002.

MMC increased its quarterly dividend by 11% to $.31 per share effective with the dividend to be paid on August 15, 2003.

Financing Cash Flows
In February 2003, MMC issued $250 million of 3.625% Senior Notes due in 2008 and $250 million of 4.85% Senior Notes due in 2013 (the "2003 Notes"). The net proceeds from the 2003 Notes were used to pay down commercial paper borrowings. Commercial paper outstanding decreased $640 million during the first six months of 2003 as a result of these repayments.

In January 2003, MMC terminated and settled interest rate swaps that had hedged the fair value of senior notes issued in 2002. The cumulative amount of previously recognized adjustments of the fair value of the hedged notes is being amortized over the remaining life of those notes in accordance with SFAS No.
133. As a result, the effective interest rate over the remaining life of the notes, including the amortization of the fair value adjustments, is 4.0% for the $500 million Senior Notes due in 2007 (5.375% coupon rate) and 5.1% for the $250 million Senior Notes due in 2012 (6.25% coupon rate).

22

In July 2003, MMC issued $300 million of 5.875% Senior Notes due in 2033.

During the first six months of 2003, MMC repurchased 11.5 million shares of its common stock at a cost of $503 million. MMC repurchases shares subject to market conditions, including from time to time pursuant to the terms of a 10b5-1 plan. A 10b5-1 plan allows a company to purchase shares during a blackout period, provided the company communicates its share purchase instructions to the broker prior to the blackout period, pursuant to a written plan that may not be changed.

Investing Cash Flows
MMC's additions to fixed assets and capitalized software, which amounted to $240 million in the first six months of 2003 and $187 million in the first six months last year, primarily relate to computer equipment purchases and the refurbishing and modernizing of office facilities and software development costs.

MMC has committed to potential future investments of approximately $440 million in connection with various MMC Capital funds and other MMC investments. Approximately $35 million is expected to be invested during the remainder of 2003. MMC expects to fund future commitments, in part, with sales proceeds from existing investments.

Market Risk
Certain of MMC's revenues, expenses, assets and liabilities are exposed to the impact of interest rate changes and fluctuations in foreign currency exchange rates and equity markets.

Interest Rate Risk
MMC manages its net exposure to interest rate changes by utilizing a mixture of variable and fixed rate borrowings to finance MMC's asset base. Interest rate swaps are used on a limited basis to manage MMC's exposure to interest rate movements on its cash and investments, as well as interest expense on borrowings, and are only executed with counterparties of high creditworthiness.

Foreign Currency Risk
The translated values of revenue and expense from MMC's international risk and insurance services and consulting operations are subject to fluctuations due to changes in currency exchange rates. Forward contracts and options are periodically utilized by MMC to limit foreign currency exchange rate exposure on net income and cash flows for specific, clearly defined transactions arising in the ordinary course of its business.

Equity Price Risk
MMC holds investments in both public and private companies as well as certain private equity funds managed by MMC Capital including Trident II. Publicly traded investments of $346 million are classified as available for sale under SFAS No. 115. Non-publicly traded investments of $155 million and $311 million are accounted for under APB Opinion No. 18 using the cost method and the equity method, respectively. The investments are subject to risk of changes in market value, which if determined to be other than temporary, could result in realized impairment losses. MMC periodically reviews the carrying value of such investments to determine if any valuation adjustments are appropriate under the applicable accounting pronouncements.

23

MMC Capital helped develop an additional source of insurance and reinsurance capacity after September 11 through the formation of AXIS Specialty Holdings ("AXIS"), a Bermuda domiciled insurance company. AXIS had an initial capitalization of $1.6 billion, which included a $250 million investment by Trident II and a $100 million direct investment by MMC. AXIS completed an initial public offering on July 1, 2003. MMC's direct investment is currently carried at cost and will be classified as an available for sale security, as restrictions on the sale of AXIS shares expire, with changes in fair value recorded in other comprehensive income until realized. Trident II's investments are carried at fair value, in accordance with investment company accounting. MMC's proportionate share of the change in value of its investment in Trident II is recorded as part of investment income (loss) in the Consolidated Income Statement.

MMC utilizes option contracts to hedge the variability of cash flows from forecasted sales of certain available for sale investments. The hedge is achieved through the use of European style put and call options, which mature on the dates of the forecasted sales. The hedges are only executed with counterparties of high creditworthiness.

Other
The insurance coverage for potential liability resulting from alleged errors and omissions in the professional services provided by MMC includes elements of both risk retention and risk transfer. MMC believes it has adequately reserved for the self-insurance portion of the contingencies. Payments related to the respective self-insured layers are made as legal fees are incurred and claims are resolved and generally extend over a considerable number of years. The amounts paid in that regard vary in relation to the severity of the claims and the number of claims active in any particular year. The long-term portion of this liability is included in Other liabilities in the Consolidated Balance Sheets.

New Accounting Pronouncements
New accounting pronouncements are discussed in Note 15 to the Consolidated Financial Statements.

Section 1.02 . Amendment to Article IV. Article IV of the Indenture is hereby amended to include the following covenant with respect to the Notes only (and not with respect to any other series of securities issuable pursuant to the Indenture unless the supplemental indenture relating thereto expressly so provides), which reads in its entirety as follows:

Section 4.06. Limitation on Liens on Stock of Significant Subsidiaries. The Company will not, and it will not permit any Subsidiary of the Company to, at any time directly or indirectly create, assume, incur or permit to exist any Indebtedness secured by a pledge, lien or other encumbrance (any pledge, lien or other encumbrance being hereinafter in this Section referred to as a

2

"lien") on the voting stock or voting equity interest of Marsh Inc., Putnam, LLC or Mercer Inc. (each a "Significant Subsidiary") without making effective provision whereby the Notes then Outstanding (and, if the Company so elects, any other Indebtedness of the Company that is not subordinate to the Notes and with respect to which the governing instruments require, or pursuant to which the Company is otherwise obligated or required, to provide such security) shall be equally and ratably secured with such secured Indebtedness so long as such other Indebtedness shall be so secured.

"Indebtedness" of any person means the principal of and premium, if any, and interest due on indebtedness of such Person, whether outstanding on the date of this Indenture or thereafter created, incurred or assumed, which is (a) indebtedness for money borrowed, and (b) any amendments, renewals, extensions, modifications and refundings of any such indebtedness. For the purposes of this definition, "indebtedness for money borrowed" means (i) any obligation of, or any obligation guaranteed by, such Person for the repayment of borrowed money, whether or not evidenced by bonds, debentures, notes or other written instruments, (ii) any obligation of, or any such obligation guaranteed by, such Person evidenced by bonds, debentures, notes or similar written instruments, including obligations assumed or incurred in connection with the acquisition of properly, assets or businesses (provided, however, that the deferred purchase price of any business or property or assets shall not be considered Indebtedness if the purchase price thereof is payable in full within 90 days from the date on which such indebtedness was created), and (iii) any obligations of such Person as lessee under leases required to be capitalized on the balance sheet of the lessee under generally accepted accounting principles and leases of property or assets made as part of any sale and lease-back transaction to which such Person is a party. For purposes of this covenant only, Indebtedness also includes any obligation of, or any obligation guaranteed by, any Person for the payment of amounts due under a swap agreement or similar instrument or agreement, or under a foreign currency hedge or similar instrument or agreement.

If the Company shall hereafter be required to secure the Notes equally and ratably with any other Indebtedness pursuant to this Section, (i) the Company will promptly deliver to the Trustee an Officers' Certificate stating that the foregoing covenant has been complied with, and an Opinion of Counsel stating that in the opinion of such counsel the foregoing covenant has been complied

3

with and (ii) the Trustee is hereby authorized to enter into an indenture or agreement supplemental hereto and to take such action, if any, as it may deem advisable to enable it to enforce the rights of the holders of the Notes so secured.

Section 1.03 . Amendment of Article Ten. Article Ten of the Indenture is hereby amended and restated in its entirety with respect to the Notes only (and not with respect to any other series of securities issuable pursuant to the Indenture unless the supplemental indenture relating thereto expressly so provides) as follows:

Section 10.01. Company May Consolidate, Etc., Only on Certain Terms. (a) Subject to Section 10.01(c) below, the Company shall not consolidate with or merge into any other Person or convey, transfer or lease all or substantially all of its properties and assets to any Person, and the Company shall not permit any Person to consolidate with or merge into the Company, unless:

(1) in case the Company shall consolidate with or merge into another Person or convey, transfer or lease all or substantially all of its properties and assets to any Person, the Person formed by such consolidation or into which the Company is merged or the Person which acquires by conveyance or transfer, or which leases, all or substantially all of the properties and assets of the Company shall be a corporation, partnership or trust, shall be organized and validly existing under the laws of the United States of America, any State thereof or the District of Columbia and shall expressly assume, by an indenture supplemental hereto, executed and delivered to the Trustee, the due and punctual payment of the principal of and any premium and interest on all the Securities and the performance or observance of every covenant of this Indenture on the part of the Company to be performed or observed;

(2) immediately after giving effect to such transaction, no Event of Default, and no event which, after notice or lapse of time or both, would become an Event of Default, shall have happened and be continuing; and

(3) the Company has delivered to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that such consolidation, merger, conveyance, transfer or lease and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture comply with this Article and that all conditions precedent herein provided for relating to such transaction have been complied with.

4

Section 10.02. Successor Substitute. Upon any consolidation of the Company with, or merger of the Company into, any other Person or any conveyance, transfer or lease of all or substantially all of the properties and assets of the Company in accordance with Section 10.01 above, the successor Person formed by such consolidation or into which the Company is merged or to which such conveyance, transfer or lease is made shall succeed to, and be substituted for, and may exercise every right and power of, the Company under the Indenture with the same effect as if such successor Person had been named as the Company herein, and thereafter, except in the case of a lease, the predecessor Person shall be relieved of all obligations and covenants under the Indenture and the Notes.

Section 10.03. Evidence of Consolidation, Etc. to Trustee. The Trustee, subject to the provisions of Section 7.01, may receive an Opinion of Counsel as conclusive evidence that any such consolidation, merger, sale, conveyance, transfer or other disposition, and any such assumption, comply with the provisions of this Article.

Section 1.04 . Trustee's Obligations with Respect to the Covenants. The Trustee shall not be obligated to monitor or confirm, on a continuing basis or otherwise, the Issuer's compliance with the covenants contained in this Article One or with respect to reports or other documents filed under the Indenture; provided, however, that nothing herein shall relieve the Trustee of any obligations to monitor the Issuer's timely delivery of all reports and certificates required under Sections 5.01 and 5.03 of the Indenture and to fulfill its obligations under Article Seven of the Indenture.

Section 1.05 . Form Of Note. The form of the Notes is attached hereto as Exhibit A.

Section 2.05 . Separability. In case any provision in this Third Supplemental Indenture shall for any reason be held to be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

Section 2.06 . Counterparts. This Third Supplemental Indenture may be executed in any number of counterparts each of which shall be an original, but such counterparts shall together constitute but one and the same instrument.

5.875% Senior Notes
due August 1, 2033

MARSH & McLENNAN COMPANIES, INC., a Delaware corporation (the "Company", which term includes any successor corporation under the Indenture hereinafter referred to), for value received, hereby promises to pay to CEDE & Co., or its registered assigns, the principal sum of 300,000,000 Dollars ($300,000,000) on August 1, 2033 and to pay interest on said principal sum from July 30, 2003 or from the most recent interest payment date (each such date, an "Interest Payment Date") to which interest has been paid or duly provided for, semiannually on February 1 and August 1 of each year commencing February 1, 2004 at the rate of 5.875% per annum until the principal hereof shall have become

9

due and payable, and on any overdue principal and premium, if any, and (without duplication and to the extent that payment of such interest is enforceable under applicable law) on any overdue installment of interest at the same rate per annum. The amount of interest payable on any Interest Payment Date shall be computed on the basis of a 360-day year of twelve 30-day months. In the event that any date on which interest is payable on this Note is not a Business Day, then payment of interest payable on such date will be made on the next succeeding day which is a Business Day (and without any interest or other payment in respect of any such delay), except that, if such Business Day is in the next succeeding calendar year, such payment shall be made on the immediately preceding Business Day, in each case with the same force and effect as if made on such date. The interest installment so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in the Indenture, be paid to the person in whose name this Note (or one or more Predecessor Securities, as defined in said Indenture) is registered at the close of business on the Regular Record Date for such interest installment which shall be January 15 or July 15 preceding such Interest Payment Date. Any such interest installment not punctually paid or duly provided for (as defined in the Indenture, the "Defaulted Interest") shall forthwith cease to be payable to the registered holders on such regular record date, and may be paid to the person in whose name this Note (or one or more Predecessor Securities) is registered at the close of business on a special record date to be fixed by the Trustee for the payment of such Defaulted Interest, which shall not be more than 15 nor less than 10 days prior to the date of the proposed payment, and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment or at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange, all as more fully provided in the Indenture. The principal of (and premium, if any) and the interest on this Note shall be payable at the office or agency of the Trustee maintained for that purpose in any coin or currency of the United States of America which at the time of payment is legal tender for payment of public and private debts; provided, however, that payment of interest may be made at the option of the Company by check mailed to the registered holder at such address as shall appear in the Security Register. Notwithstanding the foregoing, so long as the Holder of this Note is Cede & Co., the payment of the principal of (and premium, if any) and interest on this Note will be made at such place and to such account as may be designated by DTC.

The indebtedness evidenced by this Note is, to the extent provided in the Indenture, senior and unsecured and will rank in right of payment on parity with all other senior unsecured obligations of the Company.

This Note shall not be entitled to any benefit under the Indenture hereinafter referred to, be valid or become obligatory for any purpose until the

10

Certificate of Authentication hereon shall have been signed by or on behalf of the Trustee.

The provisions of this Note are continued on the reverse side hereof and such continued provisions shall for all purposes have the same effect as though fully set forth at this place.

MARSH & McLENNAN COMPANIES, INC.
5.875% Senior Notes due 2033

This Note is one of a duly authorized series of Securities of the Company (herein sometimes referred to as the "Notes"), specified in the Indenture, all issued or to be issued in one or more series under and pursuant to an indenture (the "Base Indenture") dated as of June 14, 1999 between the Company, and U.S. Bank National Association (as successor to State Street Bank and Trust Company), as Trustee (the "Trustee"), as supplemented by the Third Supplemental Indenture dated as of July 30, 2003 between the Company and the Trustee (the Base Indenture as so supplemented, the "Indenture"), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the holders of the Notes. This series of Notes is limited in aggregate principal amount as specified in said Third Supplemental Indenture.

The Indenture contains provisions permitting the Company and the Trustee, with the consent of the Holders of not less than a majority in aggregate principal amount of the Notes of each series affected at the time Outstanding, as defined in the Indenture, to execute supplemental indentures for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of any supplemental indenture or of modifying in any manner the rights of the Holders of the Notes; provided, however, that no such supplemental indenture shall, without the consent of the holders of each Note then Outstanding and affected thereby (i) extend the fixed maturity of any Notes of any series, or reduce the principal amount thereof, or reduce the rate or extend the time of payment of interest thereon, or reduce any premium payable upon the redemption thereof, or (ii) reduce the aforesaid percentage of Notes, the Holders of which are required to consent to any such supplemental indenture. The Indenture also contains provisions permitting the Holders of a majority in aggregate principal amount of the Notes of any series at the time Outstanding affected thereby, on behalf of all of the Holders of the Notes of such series, to waive any past default in the performance of any of the covenants contained in the Indenture, or established pursuant to the Indenture with respect to such series, and its consequences, except a default in the payment of the principal of or premium, if any, or interest on any of the Notes of such series and except as provided in Section 6.06 of the Base Indenture. Any such consent or waiver by the registered Holder of this Note (unless revoked as provided in the Indenture) shall be conclusive and binding upon such Holder and upon all future Holders and owners of this Note and of any Note issued in exchange herefor or in place hereof (whether by registration of transfer or otherwise), irrespective of whether or not any notation of such consent or waiver is made upon this Note.

15

No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and premium, if any, and interest on this Note at the time and place and at the rate and in the money herein prescribed.

The Issuer is subject to certain covenants contained in the Indenture with respect to, and for the benefit of the Holders of, the Notes. The Trustee shall not be obligated to monitor or confirm, on a continuing basis or otherwise, the Issuer's compliance with the covenants contained in the Indenture or with respect to reports or other certificates filed under the Indenture; provided, however, that nothing herein shall relieve the Trustee of any obligations to monitor the Issuer's timely delivery of all reports and certificates required under Section 5.03 of the Indenture and to fulfill its obligations under Article VII of the Indenture. If an Event of Default as defined in the Indenture with respect to the Notes shall occur and be continuing, the principal of the Notes may be declared due and payable in the manner and with the effect provided in the Indenture.

As provided in and subject to the provisions of the Indenture, the Holder of this Note shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Notes, the Holders of not less than 25% in principal amount of the Notes at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity and the Trustee shall have failed to institute any such proceeding for 60 days after receipt of such notice, request and offer of indemnity and the Trustee shall not have received from the Holders of a majority in principal amount of the Notes at the time Outstanding a direction inconsistent with such request. The foregoing shall not apply to any suit instituted by the Holder of this Note for the enforcement of any payment of principal hereof or any interest on or after the respective due dates expressed herein.

As provided in the Indenture and subject to certain limitations therein set forth, this Note is transferable by the registered holder hereof on the Security Register of the Company, upon surrender of this Note for registration of transfer at the office or agency of the Company in the borough of Manhattan, the City and State of New York accompanied by a written instrument or instruments of transfer in form satisfactory to the Company or the Trustee duly executed by the registered holder hereof or his attorney duly authorized in writing, and thereupon one or more new Notes of authorized denominations and for the same aggregate principal amount and series will be issued to the designated transferee or transferees. No service charge will be made for any such transfer,

16

but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in relation thereto.

Prior to due presentment for registration of transfer of this Note, the Company, the Trustee, any paying agent and any Security Registrar may deem and treat the registered holder hereof as the absolute owner hereof (whether or not this Note shall be overdue and notwithstanding any notice of ownership or writing hereon made by anyone other than the Security Registrar) for the purpose of receiving payment of or on account of the principal hereof and premium, if any, and interest due hereon and for all other purposes, and neither the Company nor the Trustee nor any paying agent nor any Note Registrar shall be affected by any notice to the contrary.

No recourse shall be had for the payment of the principal of or the interest on this Note, or for any claim based hereon, or otherwise in respect hereof, or based on or in respect of the Indenture, against any incorporator, stockholder, officer or director, past, present or future, as such, of the Company or of any predecessor or successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as part of the consideration for the issuance hereof, expressly waived and released.

The Notes of this series are issuable only in registered form without coupons in authorized denominations. As provided in the Indenture and subject to certain limitations herein and therein set forth, Notes of this series so issued are exchangeable for a like aggregate principal amount of Notes of this series of a different authorized denomination, as requested by the Holder surrendering the same.

All terms used in this Note which are defined in the Indenture shall have the meanings assigned to them in the Indenture.

THE INDENTURE AND THE NOTES INCLUDING THIS NOTE SHALL BE GOVERNED BY

AND CONSTRUED IN ACCORDANCE WITH THE LAW OF THE STATE OF NEW YORK.

Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Issuer has caused "CUSIP" numbers to be printed on the Notes as a convenience to the Holders of the Notes. No representation is made as to the correctness or accuracy of such CUSIP numbers as printed on the Notes, and reliance may be placed only on the other identification numbers printed hereon.

17

Unless the certificate of authentication hereon has been executed by or on behalf of the Trustee by manual signature, this Note shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purposes.
