Description of Securities

This prospectus contains a summary of the securities that the Company or certain selling securityholders may sell. These summaries are not meant to be a complete description of each security. However, this prospectus and the accompanying prospectus supplement contain the material terms of the securities being offered.

Description of Capital Stock

The following description is based upon our restated certificate of incorporation, our amended and restated bylaws and applicable provisions of law. We have summarized certain portions of the restated certificate of incorporation and amended and restated bylaws below. The summary is not complete. The restated certificate of incorporation and amended and restated bylaws are incorporated by reference into this prospectus in their entirety. You should read the restated certificate of incorporation and amended and restated bylaws for the provisions that are important to you.

The Company’s authorized capital stock consists of 1,600,000,000 shares of common stock and 6,000,000 shares of preferred stock. As of July 24, 2018, there were 504,979,546 shares of common stock outstanding. No shares of preferred stock were issued or outstanding as of July 24, 2018.

Common Stock

Voting Rights. Each holder of common stock is entitled to one vote for each share held on all matters to be voted upon by stockholders.

Dividends. The holders of common stock, after any preferences of holders of any preferred stock, are entitled to receive dividends when and if declared by the board of directors out of legally available funds.

Liquidation and Dissolution. If the Company is liquidated or dissolved, the holders of the common stock will be entitled to share in the assets of the Company available for distribution to stockholders in proportion to the amount of common stock they own. The amount available for common stockholders is calculated after payment of liabilities. Holders of any preferred stock will receive their preferential share of the assets of the Company before the holders of the common stock receive any assets.

Other rights. Holders of the common stock have no right to:

•

convert the stock into any other security;

•

have the stock redeemed; or

•

purchase additional stock or to maintain their proportionate ownership interest

The common stock does not have cumulative voting rights. Holders of shares of the common stock are not required to make additional capital contributions.

Directors’ Liability

Our restated certificate of incorporation provides that a member of the board of directors will not be personally liable to the Company or its stockholders for monetary damages for breaches of their legal duties to the Company or its stockholders as a director, except for liability:

•

for any breach of the director’s legal duty to act in the best interests of the Company and its stockholders;

•

for acts or omissions by the director with dishonest intentions or which involve intentional misconduct or an intentional violation of the law;

•

for declaring dividends or authorizing the purchase or redemption of shares in violation of Delaware law; or

•

for transactions where the director derived an improper personal benefit.

Our restated certificate of incorporation also allows us to indemnify directors and officers to the fullest extent authorized by Delaware law.

Transfer Agent and Registrar

Equiniti Trust Company (formerly, Wells Fargo Bank, N.A.) is transfer agent and registrar for the common stock.

Provisions of the Company’s Restated Certificate of Incorporation and Amended and Restated ByLaws and Delaware Law That May Have Anti-Takeover Effects

Stockholder Nomination of Directors. The Company’s amended and restated bylaws provide that a stockholder must notify the Company in writing of any stockholder nomination of a director not earlier than 5:00 p.m. Eastern Time on the 120th day and not later than 5:00 p.m. Eastern Time on the 90th day prior to the first anniversary of the preceding year’s annual meeting; provided, that if the date of the annual meeting is advanced or delayed by more than 30 days from such anniversary date, notice by the stockholder to be timely must be so delivered not earlier than 5:00 p.m. Eastern Time on the 120th day prior to the date of such annual meeting and not later than 5:00 p.m. Eastern Time on the later of (x) the 90th day prior to the date of such annual meeting and (y) the 10th day following the day on which public announcement of the date of such annual meeting is first made by the Company.

Proxy Access. The Company’s amended and restated bylaws contain “proxy access” provisions which give an eligible stockholder (or a group of up to 20 stockholders aggregating their shares), that has owned 3% or more of the Company’s outstanding common stock continuously for at least three years, the right to nominate and include in our proxy materials the greater of two nominees or 20% of the number of directors to be elected at the applicable annual general meeting, subject to the other terms and conditions of our bylaws.

No Action By Written Consent. Our restated certificate of incorporation provides that stockholders of the Company may not act by written consent and may only act at duly called meetings of stockholders.

10% Stockholder Provision. Article Eighth of our restated certificate of incorporation changes the voting requirements for stockholders to approve certain transactions involving, or proposed by or on behalf of, a 10% stockholder or an affiliate or associate of a 10% stockholder. Business combinations are an example of the type of transaction addressed. These transactions must be approved by the holders of a majority of the Company’s outstanding voting power, voting together as a single class. Any voting stock owned by a 10% stockholder is not counted in the vote. These transactions, however, can also be approved by a majority of unbiased directors. In that case, the voting requirements of Delaware law, our restated certificate of incorporation and our amended and restated bylaws that otherwise apply would govern the vote. Article Eighth does not affect the voting requirements of holders of preferred stock, if any, which arise under Delaware law and the restated certificate of incorporation.

Transactions covered by Article Eighth include:

•

mergers of the Company or any of its subsidiaries with a 10% stockholder,

•

sales of all or any substantial part of the assets of the Company and its subsidiaries to a 10% stockholder,

•

sales of all or any substantial part of the assets of a 10% stockholder to the Company,

•

the issuance or delivery of securities of the Company or any of its subsidiaries to a 10% stockholder, or of securities of a 10% stockholder to the Company,

•

any substantial loan, advance or guarantee, pledge or other financial assistance provided by the Company or any of its subsidiaries to a 10% stockholder,

•

the adoption of a plan for the voluntary dissolution or liquidation of the Company or amendment to the Company’s amended and restated bylaws,

•

any reclassification of securities or recapitalization of the Company or other transaction which increases a 10% stockholder’s proportionate share of any class of the Company’s capital stock, or

•

any agreement or other arrangement to do any of the foregoing.

A 10% stockholder is described in Article Eighth as an “Interested Stockholder.” A 10% stockholder is generally considered to be any other corporation, person or entity which:

•

beneficially owns or controls, directly or indirectly, 10% or more of the voting stock of the Company or has announced a plan or intention to acquire such securities, or

•

is an affiliate or associate of the Company and at any time within two years prior to the date in question was the beneficial owner of 10% or more of the voting stock of the Company.

The following are not considered to be 10% stockholders:

•

the Company and any of its subsidiaries, and

•

any profit-sharing, employee stock ownership or other employee benefit plan of the Company or any subsidiary, or trustees or fiduciaries for these plans.

An unbiased director is described in Article Eighth as a “Disinterested Director.” An unbiased director is generally considered to be a director who:

•

is not related to a 10% stockholder, and was a member of the board of directors prior to the time that the relevant 10% stockholder became a 10% stockholder, or

•

is a successor to an unbiased director, who is not related to a 10% stockholder and was nominated by a majority of unbiased directors.

A director is considered related to a 10% stockholder if he is an affiliate, associate, representative, agent or employee of the 10% stockholder.

Any proposal by a 10% stockholder, or by an affiliate or associate of a 10% stockholder, to change or repeal all or any part of Article Eighth requires the affirmative vote of the holders of a majority of the Company’s outstanding voting power, voting together as a single class. Any voting stock owned by a 10% stockholder will not be counted in the vote. However, if a majority of unbiased directors recommends a change in Article Eighth, the standard voting requirements of Delaware law, our restated certificate of incorporation and our amended and restated bylaws that otherwise apply will govern the vote.

Delaware Business Combination Statute. Section 203 of the General Corporation Law of the State of Delaware (the “DGCL”), is applicable to the Company. Section 203 of the DGCL restricts some types of transactions and business combinations between a corporation and a 15% stockholder. A 15% stockholder is generally considered by Section 203 to be a person owning 15% or more of the corporation’s outstanding voting stock. Section 203 refers to a 15% stockholder as an “interested stockholder.” Section 203 restricts these transactions for a period of three years from the date the stockholder acquires 15% or more of the Company’s outstanding voting stock. With some exceptions, unless the transaction is approved by the board of directors and the holders of at least two-thirds of the outstanding voting stock of the corporation, Section 203 prohibits significant business transactions such as:

•

a merger with, disposition of significant assets to or receipt of disproportionate financial benefits by the interested stockholder, and

•

any other transaction that would increase the interested stockholder’s proportionate ownership of any class or series of the Company’s capital stock.

The shares held by the interested stockholder are not counted as outstanding when calculating the two-thirds of the outstanding voting stock needed for approval.

The prohibition against these transactions does not apply if:

•

prior to the time that any stockholder became an interested stockholder, the board of directors approved either the business combination or the transaction in which such stockholder acquired 15% or more of the Company’s outstanding voting stock, or

•

the interested stockholder owns at least 85% of the outstanding voting stock of the Company as a result of the transaction in which such stockholder acquired 15% or more of the Company’s outstanding voting stock. Shares held by persons who are both directors and officers or by some types of employee stock plans are not counted as outstanding when making this calculation.

Listing. Our common stock is listed on the New York and Chicago Stock Exchanges under the trading symbol “MMC” and on the London Stock Exchange under the trading symbol “MHM.”

Preferred Stock

General. The Company is authorized to issue 6,000,000 shares of preferred stock. No shares of preferred stock are currently issued or outstanding. The board of directors of the Company may, without stockholder approval, issue shares of preferred stock. The board of directors can issue more than one series of preferred stock. The board of directors has the right to fix the number of shares, dividend rights, conversion rights, voting rights, redemption rights, sinking fund provisions, liquidation preferences and any other rights, preferences, privileges and restrictions applicable to the preferred stock it decides to issue.

Voting Rights. The DGCL provides that the holders of preferred stock will have the right to vote separately as a class on any proposal involving fundamental changes in the rights of holders of such preferred stock.

Conversion or Exchange. If we offer preferred stock, the applicable prospectus supplement will describe the terms, if any, on which the preferred stock may be convertible into or exchangeable for common stock, debt securities or other preferred stock of the Company. These terms will include provisions as to whether conversion or exchange is mandatory, at the option of the holder or at the option of the Company. These provisions may allow or require the number of shares of common stock or other securities of the Company to be received by the holders of preferred stock to be adjusted.

Depositary Shares Representing Preferred Stock

The applicable prospectus supplement will include a description of the material terms of any depositary shares representing preferred stock offered hereby.

Description of Debt Securities

The debt securities will be our direct unsecured general obligations. The debt securities will be either senior debt securities or subordinated debt securities. The debt securities will be issued under one or more separate indentures between us and The Bank of New York Mellon, as trustee. Senior debt securities will be issued under a senior indenture between us and The Bank of New York Mellon, as trustee, which we refer to as the senior indenture. Subordinated debt securities will be issued under a subordinated indenture to be executed between us and The Bank of New York Mellon, as trustee, which we refer to as the subordinated indenture. Together the senior indenture and the subordinated indenture are called the indentures.

We have summarized all of the material provisions of the indentures below. The senior indenture and subordinated indenture have been filed as exhibits to the registration statement of which this prospectus forms a part, and you should read the indentures for provisions that may be important to you. In the summary below, we have included references to section numbers of the indentures so that you can easily locate these provisions.

General

The debt securities will be our direct unsecured general obligations. The senior debt securities will rank equally with all of our other senior and unsubordinated debt. The subordinated debt securities will have a junior position to all of our senior debt.

Because we are a holding company that conducts all of its operations through subsidiaries, holders of the debt securities will have a junior position to claims of creditors of our subsidiaries, including trade creditors, debt holders, secured creditors, taxing authorities, guarantee holders and any preferred stockholders.

The provisions of each indenture allow us to “reopen” a previous issue of a series of debt securities and issue additional debt securities of that series.

A prospectus supplement relating to any series of debt securities being offered will include specific terms relating to the offering. The terms will be established in an officers’ certificate or a supplemental indenture. The officers’ certificate or supplemental indenture will be signed at the time of issuance and will contain important information. The officers’ certificate or supplemental indenture will be filed as an exhibit to a Current Report on Form 8-K of the Company, which will be publicly available. The officers’ certificate or supplemental indenture will include some or all of the following terms for a particular series of debt securities:

•

the title of the securities;

•

any limit on the amount that may be issued;

•

whether or not the debt securities will be issued in global form and who the depositary will be;

•

the maturity date(s);

•

the interest rate or the method of computing the interest rate;

•

the date or dates from which interest will accrue, or how such date or dates will be determined, and the interest payment date or dates and any related record dates;

•

the place(s) where payments will be made;

•

the Company’s right, if any, to defer payment of interest and the maximum length of any deferral period;

•

the terms and conditions on which the debt securities may be redeemed at the option of the Company;

•

the date(s), if any, on which, and the price(s) at which the Company is obligated to redeem, or at the holder’s option to purchase, such series of debt securities and other related terms and provisions;

•

any provisions granting special rights to holders when a specified event occurs;

•

any changes to or additional events of default or covenants;

•

any special tax implications of the debt securities;

•

the denominations in which the debt securities will be issued, if other than denominations of $1,000 and whole multiples of $1,000;

•

the subordination terms of any subordinated debt securities; and

•

any other terms that are not inconsistent with the indenture. (section 2.01)

Fixed Rate Debt Securities

Each fixed rate debt security will mature on the date specified in the applicable prospectus supplement.

Each fixed rate debt security will bear interest from the date of issuance at the annual rate stated on its face until the principal is paid or made available for payment. Interest on fixed rate debt securities will be computed on the basis of a 360-day year of twelve 30-day months. Interest on fixed rate debt securities will accrue from and including the most recent interest payment date in respect of which interest has been paid or duly provided for, or, if no interest has been paid or duly provided for, from and including the issue date or any other date specified in a prospectus supplement on which interest begins to accrue. Interest will accrue to but excluding the next interest payment date, or, if earlier, the date of maturity or earlier redemption or repayment, as the case may be.

Payments of interest on fixed rate debt securities will be made on the interest payment dates specified in the applicable prospectus supplement. However, if the first interest payment date is less than 15 days after the date of issuance, interest will not be paid on the first interest payment date, but will be paid on the second interest payment date.

Unless otherwise specified in the applicable prospectus supplement, if any scheduled interest payment date, maturity date or date of redemption or repayment is not a business day, then we may pay the applicable interest, principal and premium, if any, on the next succeeding business day, and no additional interest will accrue during the period from and after the scheduled interest payment date, maturity date or date of redemption or repayment. (section 13.07)

A fixed rate debt security may pay a level amount in respect of both interest and principal amortized over the life of the debt security. Payments of principal and interest on amortizing debt securities will be made on the interest payment dates specified in the applicable prospectus supplement, and at maturity or upon any earlier redemption or repayment. Payments on amortizing debt securities will be applied first to interest due and payable and then to the reduction of the unpaid principal amount. We will provide to the original purchaser, and will furnish to subsequent holders upon request to us, a table setting forth repayment information for each amortizing debt security.

Floating Rate Debt Securities

Each floating rate debt security will mature on the date specified in the applicable prospectus supplement.

Unless otherwise specified in the applicable prospectus supplement, each floating rate debt security will bear interest at “LIBOR” plus a margin to be specified in the applicable prospectus supplement. A floating rate debt security may also have either or both of the following limitations on the interest rate:

•

a maximum limitation, or ceiling, on the rate of interest which may accrue during any interest period, which we refer to as the “maximum interest rate”; and/or

•

a minimum limitation, or floor, on the rate of interest that may accrue during any interest period, which we refer to as the “minimum interest rate.”

Any applicable maximum interest rate or minimum interest rate will be set forth in the applicable prospectus supplement.

Interest on floating rate debt securities will accrue from and including the most recent interest payment date to which interest has been paid or duly provided for, or, if no interest has been paid or duly provided for, from and including the issue date or any other date specified in a prospectus supplement on which interest begins to accrue. Interest will accrue to but excluding the next interest payment date, or, if earlier, the date on which the principal has been paid or duly made available for payment, except as described below.

The interest rate in effect from the date of issue to the first interest reset date for a floating rate debt security will be the initial interest rate specified in the applicable prospectus supplement. We refer to this rate as the “initial interest rate.” The interest rate on each floating rate debt security may be reset daily, weekly, monthly, quarterly, semiannually or annually. This period is the “interest reset period” and the first day of each interest reset period is the “interest reset date.” The “interest determination date” for any interest reset date is the day the calculation agent will refer to when determining the new interest rate at which a floating rate will reset.

“LIBOR” for each interest reset date, other than for the initial interest rate, will be determined by the calculation agent as follows:

LIBOR will be the offered rate for deposits in U.S. dollars for the three month period which appears on “Telerate Page 3750” at approximately 11:00 a.m., London time, two “London banking days” prior to the applicable interest reset date.

ii.

If this rate does not appear on the Telerate Page 3750, the calculation agent will determine the rate on the basis of the rates at which deposits in U.S. dollars are offered by four major banks in the London interbank market selected by us at approximately 11:00 a.m., London time, two London banking days prior to the applicable interest reset date to prime banks in the London interbank market for a period of three months commencing on that interest reset date and in principal amount equal to an amount not less than $1,000,000 that is representative for a single transaction in such market at such time. In such case, the calculation agent will request the principal London office of each of the aforesaid major banks to provide a quotation of such rate. If at least two such quotations are provided, LIBOR for that interest reset date will be the average of the quotations. If fewer than two quotations are provided as requested, LIBOR for that interest reset date will be the average of the rates quoted by three major banks in New York, New York selected by us at approximately 11:00 a.m., New York time, two London banking days prior to the applicable interest reset date for loans in U.S. dollars to leading banks for a period of three months commencing on that interest reset date and in a principal amount equal to an amount not less than $1,000,000 that is representative for a single transaction in such market at such time; provided that if fewer than three quotations are provided as requested, for the period until the next interest reset date, LIBOR will be the same as the rate determined on the immediately preceding interest reset date.

The interest reset dates will be specified in the applicable prospectus supplement. If an interest reset date for any floating rate debt security falls on a day that is not a business day, it will be postponed to the following business day, except that, if that business day is in the next calendar month, the interest reset date will be the immediately preceding business day.

A “London banking day” is any day in which dealings in U.S. dollar deposits are transacted in the London interbank market. “Telerate Page 3750” means the display page so designated on the Telerate Service for the purpose of displaying London interbank offered rates of major banks (or any successor page).

The applicable prospectus supplement will specify a calculation agent for any issue of floating rate debt securities. The calculation agent will, upon the request of the holder of any floating rate debt security, provide the interest rate then in effect. All calculations made by the calculation agent in the absence of willful misconduct, bad faith or manifest error shall be conclusive for all purposes and binding on us and the holders of the floating rate debt securities. We may appoint a successor calculation agent at any time at our discretion and without notice.

All percentages resulting from any calculation of the interest rate with respect to the floating rate debt securities will be rounded, if necessary, to the nearest one-hundred thousandth of a percentage point, with five one-millionths of a percentage point rounded upward (e.g., 9.876545% (or .09876545) would be rounded to 9.87655% (or .0987655) and 9.876544% (or .09876544) would be rounded to 9.87654% (or .0987654)), and all dollar amounts in or resulting from any such calculation will be rounded to the nearest cent (with one-half cent being rounded upward).

Interest on the floating rate debt securities will be computed and paid on the basis of a 360-day year and the actual number of days in each interest payment period. The interest rate on the floating rate debt securities will in no event be higher than the maximum rate permitted by New York law, as the same may be modified by United States law of general application.

We will pay interest on floating rate debt securities on the interest payment dates specified in the applicable prospectus supplement. However, if the first interest payment date is less than 15 days after the date of issuance, interest will not be paid on the first interest payment date, but will be paid on the second interest payment date. If any scheduled interest payment date, other than the maturity date or any earlier redemption or repayment date, for any floating rate debt security falls on a day that is not a business day, it will be postponed to the following business day, except that if that business day would fall in the next calendar month, the interest payment date will be the immediately preceding business day. If the scheduled maturity date or any earlier redemption or repayment date of a floating rate debt security falls on a day that is not a business day, the payment of principal, premium, if any, and interest, if any, will be made on the next succeeding business day, but interest on that payment will not accrue during the period from and after the maturity, redemption or repayment date.

Conversion or Exchange Rights

The prospectus supplement will describe the terms, if any, on which a series of debt securities may be convertible into or exchangeable for our common stock, preferred stock, debt securities or other securities, or securities of third parties. These terms will include provisions as to whether conversion or exchange is mandatory, at the option of the holder or at the option of the Company. These provisions may allow or require adjustment of the number of shares of common stock or other securities of the Company to be received by the holders of such series of debt securities. (section 2.01)

Optional Redemption

Unless the prospectus supplement relating to any series of debt securities provides otherwise with respect to such series, each series of debt securities will be redeemable in whole at any time or in part from time to time, at our option, at a redemption price equal to the greater of:

•

100% of the principal amount of the series of debt securities to be redeemed; or

•

the sum of the present values of the remaining scheduled payments of principal and interest on the series of debt securities to be redeemed (exclusive of interest accrued to the date of redemption) discounted to the date of redemption on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the then current Treasury Rate plus a spread as specified in the applicable prospectus supplement.

In each case we will pay accrued and unpaid interest on the principal amount to be redeemed to the date of redemption.

“Comparable Treasury Issue” means the United States Treasury security selected by the Independent Investment Banker as having a maturity comparable to the remaining term (“Remaining Life”) of the series of debt securities to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of such series of debt securities.

“Comparable Treasury Price” means, with respect to any redemption date, (1) the average of the Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (2) if the Independent Investment Banker obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such quotations.

“Independent Investment Banker” means the investment banking institution or institutions specified in the applicable prospectus supplement and their respective successors, or, if such firms or the successors, if any, to such firm or firms, as the case may be, are unwilling or unable to select the Comparable Treasury Issue, an independent investment banking institution of national standing appointed by us.

“Reference Treasury Dealer” means the investment banking institutions specified as such in the applicable prospectus supplement; provided, however, that if any of them ceases to be a primary U.S. Government securities dealers (each a “Primary Treasury Dealer”), we will substitute another Primary Treasury Dealer.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Independent Investment Banker by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third business day preceding such redemption date.

“Treasury Rate” means, with respect to any redemption date, the rate per year equal to:

the yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently published statistical release designated “H.15(519)” or any successor publication which is published weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the caption “Treasury constant maturities,” for the maturity corresponding to the Comparable Treasury Issue; provided that, if no maturity is within three months before or after the remaining life of the series of debt securities to be redeemed, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue shall be determined and the Treasury Rate shall be interpolated or extrapolated from those yields on a straight line basis, rounding to the nearest month; or

ii.

if such release (or any successor release) is not published during the week preceding the calculation date or does not contain such yields, the rate per year equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date.

The Treasury Rate will be calculated on the third business day preceding the redemption date. As used in the immediately preceding sentence and in the definition of “Reference Treasury Dealer Quotations” above, the term “business day” means any day that is not a Saturday, Sunday or other day on which commercial banks in New York City are authorized or required by law to remain closed.

Notice of any redemption will be mailed at least 30 but not more than 90 days before the redemption date to each holder of record of the series of debt securities to be redeemed at its registered address. The notice of redemption will state, among other things, the amount of the series of debt securities to be redeemed, the redemption date, the manner in which the redemption price will be calculated and the place or places that payment will be made upon presentation and surrender of the series of debt securities to be redeemed. If less than all of a series of debt securities are to be redeemed at our option, the debt securities of that series, or portions of the debt securities of that series, to be redeemed will be selected in accordance with the procedures of the depositary. Unless we default in the payment of the redemption price with respect to any debt securities called for redemption, interest will cease to accrue on such debt securities at the redemption date. (sections 3.02 and 3.03)

The Company will not be required (i) to issue, register the transfer of or exchange any series of debt securities during a period beginning at the opening of business 15 days before the day of mailing of a notice of redemption and ending at the close of business on the day of such mailing, or (ii) to register the transfer of or

exchange any debt securities of any series so selected for redemption in whole or in part, except the unredeemed portion of any such series of debt securities being redeemed in part. (section 2.05)

Covenants

Under the indentures, the Company agrees to pay the interest, principal and any premium on the debt securities when due (section 4.01), and to maintain a place of payment (section 4.02). In addition, we must comply with the covenants described below:

Limitation on Liens on Stock of our Significant Subsidiaries. The indentures prohibit us and our subsidiaries from directly or indirectly creating, assuming, incurring or permitting to exist any Indebtedness secured by any lien on the voting stock or voting equity interest of Marsh LLC or Mercer Consulting Group, Inc. (each a “Significant Subsidiary”) unless the debt securities then outstanding (and, if we so elect, any other Indebtedness of the Company that is not subordinate to such debt securities and with respect to which we are obligated to provide such security) are secured equally and ratably with such Indebtedness for so long as such Indebtedness is so secured. “Indebtedness” is defined as the principal of and any premium and interest due on indebtedness of a person (as defined in the indentures), whether outstanding on the original date of issuance of a series of debt securities 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 (1) 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, (2) any obligation of, or any 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 property, 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 (3) 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 we are required to secure outstanding debt securities equally and ratably with other Indebtedness under this covenant, we will be required to document our compliance with the covenant and thereafter the trustee will be authorized to enter into a supplemental agreement or indenture and to take such action as it may deem advisable to enable it to enforce the rights of the holders of the outstanding debt securities so secured. (section 4.06)

Provision of Compliance Certificate. We are required under the indentures to deliver to the trustee within 120 days after the end of each fiscal year an officer’s certificate certifying as to our compliance with all conditions and covenants under the relevant indenture, or if we are not in compliance, identifying and describing the nature and status of such non-compliance. (section 4.08)

Consolidation, Merger or Sale

The indentures do not restrict the ability of the Company to merge or consolidate, or sell, convey, transfer or lease all or substantially all of its assets as long as certain conditions are met. We may only merge or consolidate with, or convey, transfer or lease all of our assets to, any person, if doing so will not result in an event of default. Any such successor, acquiror or lessor of such assets must expressly assume all of the obligations of the Company under the indentures and the debt securities and will succeed to every right and power of the Company under the indentures. Thereafter, except in the case of a lease, the predecessor or transferor of such assets will be relieved of all obligations and covenants under the relevant indenture and debt securities. (sections 10.01 and 10.02)

Events of Default Under the Indentures

The following are events of default under the indentures with respect to any series of debt securities issued:

•

we fail to pay interest when due and such failure continues for 90 days, unless the time for payment has been properly extended or deferred in accordance with the terms of the particular series;

•

we fail to pay the principal or any premium when due, unless the maturity has been properly extended in accordance with the terms of the particular series;

•

we fail to observe or perform any other covenant or agreement contained in the debt securities or the indentures, other than a covenant or agreement specifically relating to another series of debt securities, and such failure continues for 90 days after we receive a notice of default from the trustee or from the holders of at least 25% in aggregate principal amount of the outstanding debt securities of all of the affected series;

•

certain events of bankruptcy or insolvency, whether voluntary or not; and

•

any additional events of default that may be established with respect to a particular series of debt securities under the indentures, as may be specified in the applicable prospectus supplement. (section 6.01)

If, with regard to any series, an event of default resulting from a failure to pay principal, any premium or interest occurs and is continuing, the trustee or the holders of at least 25% in aggregate principal amount of the outstanding debt securities of that series may declare the principal of all debt securities of that series immediately due and payable. (section 6.01)

If an event of default other than a failure to pay principal, any premium or interest occurs and is continuing, the trustee or the holders of at least 25% in aggregate principal amount of the outstanding debt securities of all affected series (all such series voting together as a single class) may declare the principal of all debt securities of such affected series immediately due and payable. (section 6.01)

The holders of a majority in principal amount of the outstanding debt securities of all affected series (voting together as a single class) may waive any past default with respect to such series and its consequences, except a default or events of default regarding payment of principal, any premium or interest, in which case the holders of the outstanding debt securities of each affected series shall vote to waive such default or event of default as a separate class. Such a waiver will eliminate the default. (section 6.06)

Unless otherwise specified in the indentures, if an event of default occurs and is continuing, the trustee will be under no obligation to exercise any of its rights or powers under the relevant indenture unless the holders of the debt securities have offered the trustee reasonable indemnity satisfactory to the trustee against the costs, expenses and liabilities that it might incur. The holders of a majority in principal amount of the outstanding debt securities of all series affected by an event of default, voting together as a single class, or, in the event of a default in the payment of principal, any premium or interest, the holders of a majority of the principal amount outstanding of each affected series voting as a separate class, will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee, or exercising any trust or power conferred on the trustee with respect to the debt securities of such series, provided that:

•

such direction is not in conflict with any law or the applicable indenture or unduly prejudicial to the rights of holders of any other series of debt securities outstanding under the applicable indenture; and

•

unless otherwise provided under the Trust Indenture Act, the trustee need not take any action that might involve it in personal liability. (section 6.06)

A holder of the debt securities of a particular series will only have the right to institute a proceeding under the indentures or to appoint a receiver or trustee, or to seek other remedies, in each case with respect to such series of debt securities, if:

•

the holder has given written notice to the trustee of a continuing event of default;

•

in the case of an event of default relating to the payment of principal, any premium or interest, the holders of at least 25% in aggregate principal amount of the outstanding debt securities of the particular series have made written request to the trustee to institute proceedings as trustee;

•

in the case of an event of default not relating to payment of principal, any premium or interest, the holders of at least 25% in aggregate principal amount of the outstanding debt securities of all series affected by such event of default (voting together as a single class) have made written request to the trustee to institute proceedings as trustee;

•

such holders have offered the trustee such reasonable indemnity as the trustee may require to cover the cost of the proceedings; and

•

the trustee does not institute a proceeding, and does not receive conflicting directions from a majority in principal amount of the outstanding debt securities of (i) the particular series, in the case of an event of default relating to the payment of principal, any premium or interest or (ii) all affected series, in the case of an event of default not relating to the payment of principal, any premium or interest, in each case, within 60 days of receiving the written notice of an event of default. (section 6.04)

Modification of Indenture; Waiver

Without the consent of any holders of debt securities, the Company and the trustee may change an indenture:

•

to fix any ambiguity, defect or inconsistency in the indenture;

•

to effect the assumption of a successor corporation of our obligations under such indenture and the outstanding debt securities;

•

to add to our covenants for the benefit of the holders of all or any series of debt securities under such indenture or surrender any right or power we have under such indenture;

•

to change anything that does not materially adversely affect the interests of any holder of debt securities of any series; and

•

to effect certain other limited purposes described in the indenture. (section 9.01)

The rights of holders of a series of debt securities may be changed by the Company and the trustee with the written consent of the holders of a majority of the principal amount of the outstanding debt securities of all series then outstanding under the relevant indenture (all such series voting together as a single class). However, the following changes may only be made with the consent of each holder of debt securities of each series affected by the change:

•

extending the fixed maturity;

•

reducing the principal amount;

•

reducing the rate of or extending the time of payment of interest;

•

reducing any premium payable upon redemption;

•

reducing the percentage of debt securities referred to above, the holders of which are required to consent to any amendment; or

•

in respect of the subordinated indenture, making any change to the subordination terms of any debt security that would adversely affect the holders of the debt securities of that series. (section 9.02)

Form, Exchange, and Transfer

The debt securities of each series will be issued only in fully registered form without coupons in denominations of $1,000 and whole multiples of $1,000 in excess thereof. The indentures provide that debt securities of a series may be issued in temporary or permanent global form and may be issued as book-entry securities that will be deposited with The Depository Trust Company or another depositary named by the Company and identified in a prospectus supplement with respect to such series. (sections 2.03, 2.06 and 2.11)

A holder of debt securities of any series can exchange such debt securities for other debt securities of the same series, in any authorized denomination and with the same terms and aggregate principal amount. A holder may present debt securities for exchange or for registration of transfer at the office of the security registrar or at the office of any transfer agent designated by the Company for such purpose. Unless otherwise provided in the debt securities to be transferred or exchanged, no service charge will be made for any registration of transfer or exchange, but the Company may require payment of any related taxes or other governmental charges. The prospectus supplement will name the security registrar and any transfer agent initially designated for any series of debt securities. The Company may at any time change the transfer agent by written notice delivered to the trustee. (section 2.05)

If the debt securities of any series are to be redeemed, the Company will not be required to:

•

issue, register the transfer of, or exchange any debt securities of that series during a period beginning 15 days before the day of mailing of a notice of redemption and ending at the close of business on the day of mailing; or

•

register the transfer of or exchange any debt securities of a series, or a portion of a series, that has been called for redemption. (section 2.05)

Rights and Duties of the Trustee

The trustee, except when there is an event of default, will perform only those duties as are specifically stated in the indentures. If an event of default has occurred with respect to any series of debt securities, the trustee must exercise with respect to such debt securities the rights and powers it has under the indenture and use the same degree of care and skill as a prudent person would exercise or use in the conduct of his or her own affairs. Except as provided in the preceding sentence, the trustee is not required to exercise any of the powers given it by the indentures at the request of any holder of debt securities unless it is offered reasonable security or indemnity satisfactory to it against the costs, expenses and liabilities that it might incur. The trustee is not required to spend or risk its own money or otherwise become financially liable while performing its duties or exercising its rights or powers unless it reasonably believes that it will be repaid or receive adequate indemnity. The trustee will not be deemed to have any notice of any default or event of default unless a responsible officer of the trustee has actual knowledge of or receives written notice of the default which specifies the affected securities and the relevant indenture. Furthermore, the rights and protections of the trustee, including its right of indemnification under the indentures, extend to the trustee’s officers, directors, agents and employees, and will survive the trustee’s resignation and removal. (sections 7.01 and 7.02)

Payment and Paying Agents

We will pay interest on any debt securities to the person in whose name the debt securities are registered on the regular record date for the applicable interest payment date. (section 2.03)

We will pay principal, any premium and interest on the debt securities of a particular series at the office of one or more paying agents that we designate for that series. Unless otherwise stated in the applicable supplemental indenture and prospectus supplement, we will initially designate the corporate trust office of the trustee in the City of New York as our sole paying agent. We will be required to maintain a paying agent in each place of payment for the debt securities. (sections 4.01, 4.02 and 4.03)

All money we pay to a paying agent or the trustee for the payment of principal, any premium or interest on any debt security which remains unclaimed for a period of two years after the principal, premium or interest has become due and payable will, upon our request, be repaid to us, and the holder of the debt security may then look only to us for payment of those amounts. (section 11.05)

Governing Law

The indentures and the debt securities will be governed by and interpreted in accordance with the laws of the State of New York. (section 13.05)

Subordination of Subordinated Debt Securities

The subordinated debt securities will be unsecured and will be subordinate and junior in priority of payment to our other indebtedness on the terms described in the prospectus supplement relating to such securities. The subordinated indenture does not limit the amount of subordinated debt securities which we may issue, nor does it limit our ability to issue any other secured or unsecured debt. (sections 6.03 and 14.01)

The prospectus supplement relating to any series of subordinated debt securities will disclose the amount of debt of the Company that will be senior to those subordinated debt securities.

Description of Purchase Contracts

The applicable prospectus supplement will include a description of the material terms of any purchase contracts offered hereby.

Plan of Distribution

The Company and/or the selling securityholders, if applicable, may sell the securities in one or more of the following ways (or in any combination) from time to time:

•

through underwriters or dealers;

•

directly to a limited number of purchasers or to a single purchaser;

•

through agents;

•

through a combination of any such methods; or

•

through any other methods described in a prospectus supplement.

The applicable prospectus supplement will state the terms of the offering of the securities, including:

•

the name or names of any underwriters, dealers or agents;

•

the purchase price of such securities and the proceeds to be received by the Company, if any;

•

any initial public offering price;

•

any underwriting discounts or agency fees and other items constituting underwriters’ or agents’ compensation;

•

any discounts or concessions allowed or reallowed or paid to dealers; and

•

any securities exchanges on which the securities may be listed.

Any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers may be changed from time to time.

If we and/or the selling securityholders, if applicable, use underwriters in the sale, the securities will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions, including:

•

negotiated transactions;

•

at a fixed public offering price or prices, which may be changed;

•

at market prices prevailing at the time of sale;

•

at prices related to prevailing market prices; or

•

at negotiated prices.

Unless otherwise stated in a prospectus supplement, the obligations of the underwriters to purchase any securities will be conditioned on customary closing conditions and the underwriters will be obligated to purchase all securities of a series, if any are purchased.

We and/or the selling securityholders, if applicable, may sell the securities through agents from time to time. The prospectus supplement will name any agent involved in the offer or sale of the securities and any commissions we pay to them. Generally, any agent will be acting on a best efforts basis for the period of its appointment.

We and/or the selling securityholders, if applicable, may authorize underwriters, dealers or agents to solicit offers by certain purchasers to purchase the securities from the Company and/or the selling securityholders, if applicable, at the public offering price set forth in the prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. The contracts will be subject only to those conditions set forth in the prospectus supplement, and the prospectus supplement will set forth any commissions paid for solicitation of these contracts.

Underwriters and agents may be entitled under agreements entered into with the Company and/or the selling securityholders, if applicable, to indemnification by the Company and/or the selling securityholders, if applicable, against certain civil liabilities, including liabilities under the Securities Act of 1933, as amended, or to contribution with respect to payments which the underwriters or agents may be required to make. Underwriters and agents may be customers of, engage in transactions with, or perform services for the Company and its affiliates in the ordinary course of business.

Each series of securities will be a new issue of securities and will have no established trading market other than the common stock, which is listed on the New York, Chicago and London Stock Exchanges. Any underwriters to whom securities are sold for public offering and sale may make a market in the securities, but

such underwriters will not be obligated to do so and may discontinue any market making at any time without notice. The securities, other than the common stock, may or may not be listed on a national securities exchange.

Item 15. Indemnification of Directors and Officers.

Section 145 of the General Corporation Law of the State of Delaware (the “DGCL”) provides that a corporation may indemnify directors and officers, as well as employees and other individuals, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with any threatened, pending or completed actions, suits or proceedings in which such person is made a party by reason of such person being or having been a director, officer, employee or agent of the corporation. The DGCL provides that Section 145 is not exclusive of other rights to which those seeking indemnification may be entitled under any bylaw, agreement, vote of stockholders or disinterested directors or otherwise. Section 6.01 of the Company’s amended and restated bylaws provides for indemnification by the Company of its directors, officers and employees to the fullest extent permitted by the DGCL.

Section 102(b)(7) of the DGCL permits a corporation to provide in its certificate of incorporation that a director of the corporation shall not be personally liable to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except for liability for any breach of the director’s duty of loyalty to the corporation or its stockholders, for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, for unlawful payments of dividends or unlawful stock purchases, redemptions or other distributions, or for any transaction from which the director derived an improper personal benefit. The Company’s restated certificate of incorporation provides for such limitation of liability.

The Company maintains standard policies of insurance under which coverage is provided to its directors and officers against loss arising from claims made by reason of breach of duty, misstatement, error or omission committed in their capacity as directors or officers of the Company. Such policies of insurance also provide coverage to the Company with respect to payments which may be made by the Company to such officers and directors pursuant to the above indemnification provision or otherwise as a matter of law.

Item 17. Undertakings.

(a) The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement;

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

Provided, however, that paragraphs (i), (ii) and (iii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

(A) Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(B) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

(5) That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities:

The undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i) Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii) Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii) The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv) Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.
