(1)      Pursuant to Rule 416 promulgated under the Securities Act of 1933, as
         amended, this registration statement shall include (i) such additional
         shares of common stock as may be required pursuant to the anti-dilution
         provisions of the Marsh & McLennan Companies Special Severance Pay Plan
         (the "Plan") and (ii) an indeterminate amount of interests to be
         offered or sold pursuant to the Plan.

(2)      Estimated for the sole purpose of computing the registration fee.
         Calculated pursuant to Rule 457(c) based on the average of the high
         and low prices on the New York Stock Exchange on September 20, 2001.

(3)      The Preferred Stock Purchase Rights initially are attached to and trade
         with all the shares of Common Stock outstanding as of, and issued
         subsequent to, September 29, 1997, pursuant to the terms of the
         registrant's rights agreement, dated as of September 18, 1997, as
         amended on January 20, 2000. Until the occurrence of certain prescribed
         events, the Preferred Stock Purchase Rights are not exercisable, are
         evidenced by the certificates for the Common Stock and will be
         transferred only with the Common Stock. The value attributable to such
         Preferred Stock Purchase Rights, if any, is reflected in the market
         price of the Common Stock.

Pursuant to Rule 429 of the Rules and Regulations of the Securities and Exchange
Commission under the Securities Act of 1933, as amended, the prospectus included
in this registration statement also relates to shares of Common Stock previously

Item 4. Description of Securities.

         Not Applicable.

Item 5. Interests of Named Experts and Counsel.

         The legality of the securities being offered under the Marsh & McLennan
Companies Special Severance Pay Plan has been passed upon by William L. Rosoff,
General Counsel of the Company.

Item 6. Indemnification of Directors and Officers.

         Subsection (a) of Section 145 of the Delaware General Corporation Law
("DGCL") empowers a corporation to indemnify any person who was or is a party or
is threatened to be made a party to any threatened, pending or completed action,
suit or proceeding, whether civil, criminal, administrative or investigative
(other than an action by or in the right of the corporation) by reason of the
fact that he is or was a director, officer, employee or agent of the
corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise (including employee benefit plans), against
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred by him in connection with such
action, suit or proceeding if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful.

         Subsection (b) of Section 145 empowers a corporation to indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action or suit by or in the right of the
corporation to procure a judgment in its favor by reason of the fact that such
person acted in any of the capacities set forth above, against expenses
(including attorneys' fees) actually and reasonably incurred by him in
connection with the defense or settlement of such action or suit if he acted in
good faith and in a manner he reasonably believed to be in or not opposed to the
best interests of the corporation, except that no indemnification may be made in
respect of any claim, issue or matter as to which such person shall have been
adjudged to be liable to the corporation unless and only to the extent that the
Court of Chancery or the court in which such action or suit was brought shall
determine upon application that, despite the adjudication of liability but in
view of all the circumstances of the case, such person is fairly and reasonably
entitled to indemnity for such expenses which the Court of Chancery or such
other court shall deem proper.

         Section 145 further provides that to the extent a present or former
director or officer of a corporation has been successful on the merits or
otherwise in the defense of any action, suit or proceeding referred to in
subsections (a) and (b) of Section 145, or in defense of any claim, issue or
matter therein, he shall be indemnified against expenses (including attorneys'
fees) actually and reasonably incurred by him in connection therewith; that
indemnification and advancement of expenses provided for by Section 145 shall
not be deemed exclusive of any other rights to which the indemnified party may
be entitled; that indemnification and advancement of expenses provided for by
Section 145 shall, unless otherwise provided when authorized or ratified,
continue as to a person who has ceased to be a director, officer, employee or
agent and shall inure to the benefit of such person's heirs, executors and
administrators; and empowers the corporation to purchase and maintain insurance
on behalf of a director or officer of the corporation against any liability
asserted against him and incurred by him in any such capacity, or arising out of
his status as such, whether or not the corporation would have the power to
indemnify him against such liabilities under Section 145. Article SIXTH of the
Company's Restated Certificate of Incorporation and Article Sixth of the
Company's Bylaws provide that the Company shall indemnify its directors and
officers to the fullest extent authorized by the DGCL.

         The Company also provides liability insurance for its directors and
officers which provides for coverage against loss from claims made against
directors and officers in their capacity as such, including liabilities under
the Securities Act of 1933, as amended. The Company or its subsidiaries have
also agreed to indemnify certain directors and officers against loss from claims
made against such persons in connection with the performance of their duties
under certain plans and agreements. Such indemnification is generally to the
same extent as provided in the Company's By-laws.

         Section 102(b)(7) of the DGCL provides that a certificate of
incorporation may contain a provision eliminating or limiting the personal
liability of a director to the corporation or its stockholders for monetary
damages for breach of fiduciary duty as a director, provided that such provision
shall not eliminate or limit the liability of a director: (i) for any breach of
the director's duty of loyalty to the corporation or its stockholders, (ii) for
acts or omissions not in good faith or which involve intentional misconduct or
knowing violation of law, (iii) under Section 174 of the DGCL, or (iv) for any
transaction from which the director derived an improper personal benefit.
Article SIXTH of the Company's Certificate of Incorporation limits the liability
of directors to the fullest extent permitted by the DGCL.

Number                Description

5.1                   Opinion of William L. Rosoff with respect to the legality
                      of the securities being registered

23.1                  Consent of Deloitte & Touche LLP

24.1                  Powers of Attorney of certain directors of the Company
                      (incorporated by reference to the Company's Annual Report
                      on Form 10-K for the year ended December 31, 2000)

24.2                  Power of Attorney for Mr. Oscar Fanjul, a director

Item 9. Undertakings.

         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 and of the estimated
         maximum offering range may be reflected in the form of prospectus filed
         with the Securities and Exchange Commission (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 (1)(i) and (1)(ii) do not apply if the
registration statement is on Form S-3, Form S-8 or Form F-3, and the information
required to be included in a post-effective amendment by those paragraphs is
contained in periodic reports filed with or furnished to the Commission by the
registrant pursuant to Section 13 or 15(d) of the Securities Exchange Act of
1934 that are incorporated by reference in the registration statement.

         (2) That, for the purpose of determining any liability under the
Securities Act of 1933, as amended, 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.

             The undersigned registrant hereby undertakes that, for
purposes of determining any liability under the Securities Act of 1933, as
amended, each filing of the registrant's annual report pursuant to Section 13(a)
or 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.

             Insofar as indemnification for liabilities arising under the
Securities Act of 1933, as amended, 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 of 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.

(1)      Pursuant to Rule 416 promulgated under the Securities Act of 1933, as
         amended, this registration statement shall include (i) such additional
         shares of common stock as may be required pursuant to the anti-dilution
         provisions of the Marsh & McLennan Companies Special Severance Pay Plan
         (the "Plan") and (ii) an indeterminate amount of interests to be
         offered or sold pursuant to the Plan.

(2)      Estimated for the sole purpose of computing the registration fee.
         Calculated pursuant to Rule 457(c) based on the average of the high
         and low prices on the New York Stock Exchange on September 20, 2001.

(3)      The Preferred Stock Purchase Rights initially are attached to and trade
         with all the shares of Common Stock outstanding as of, and issued
         subsequent to, September 29, 1997, pursuant to the terms of the
         registrant's rights agreement, dated as of September 18, 1997, as
         amended on January 20, 2000. Until the occurrence of certain prescribed
         events, the Preferred Stock Purchase Rights are not exercisable, are
         evidenced by the certificates for the Common Stock and will be
         transferred only with the Common Stock. The value attributable to such
         Preferred Stock Purchase Rights, if any, is reflected in the market
         price of the Common Stock.

Pursuant to Rule 429 of the Rules and Regulations of the Securities and Exchange
Commission under the Securities Act of 1933, as amended, the prospectus included
in this registration statement also relates to shares of Common Stock previously
registered under the registrant's registration statement on Form S-8 (File No.
33-48803) for which a registration fee was previously paid.

for purposes of this Registration Statement to the extent that a statement

Item 4. Description of Securities.

         Not Applicable.

Item 5. Interests of Named Experts and Counsel.

         The legality of the securities being offered under the Marsh & McLennan
Companies Special Severance Pay Plan has been passed upon by William L. Rosoff,
General Counsel of the Company.

Item 6. Indemnification of Directors and Officers.

         Subsection (a) of Section 145 of the Delaware General Corporation Law
("DGCL") empowers a corporation to indemnify any person who was or is a party or
is threatened to be made a party to any threatened, pending or completed action,
suit or proceeding, whether civil, criminal, administrative or investigative
(other than an action by or in the right of the corporation) by reason of the
fact that he is or was a director, officer, employee or agent of the
corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise (including employee benefit plans), against
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred by him in connection with such
action, suit or proceeding if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful.

         Subsection (b) of Section 145 empowers a corporation to indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action or suit by or in the right of the
corporation to procure a judgment in its favor by reason of the fact that such
person acted in any of the capacities set forth above, against expenses
(including attorneys' fees) actually and reasonably incurred by him in
connection with the defense or settlement of such action or suit if he acted in
good faith and in a manner he reasonably believed to be in or not opposed to the
best interests of the corporation, except that no indemnification may be made in
respect of any claim, issue or matter as to which such person shall have been
adjudged to be liable to the corporation unless and only to the extent that the
Court of Chancery or the court in which such action or suit was brought shall
determine upon application that, despite the adjudication of liability but in
view of all the circumstances of the case, such person is fairly and reasonably
entitled to indemnity for such expenses which the Court of Chancery or such
other court shall deem proper.

         Section 145 further provides that to the extent a present or former
director or officer of a corporation has been successful on the merits or
otherwise in the defense of any action, suit or proceeding referred to in
subsections (a) and (b) of Section 145, or in defense of any claim, issue or
matter therein, he shall be indemnified against expenses (including attorneys'
fees) actually and reasonably incurred by him in connection therewith; that
indemnification and advancement of expenses provided for by Section 145 shall
not be deemed exclusive of any other rights to which the indemnified party may
be entitled; that indemnification and advancement of expenses provided for by
Section 145 shall, unless otherwise provided when authorized or ratified,
continue as to a person who has ceased to be a director, officer, employee or
agent and shall inure to the benefit of such person's heirs, executors and
administrators; and empowers the corporation to purchase and maintain insurance
on behalf of a director or officer of the corporation against any liability
asserted against him and incurred by him in any such capacity, or arising out of
his status as such, whether or not the corporation would have the power to
indemnify him against such liabilities under Section 145. Article SIXTH of the
Company's Restated Certificate of Incorporation and Article Sixth of the
Company's Bylaws provide that the Company shall indemnify its directors and
officers to the fullest extent authorized by the DGCL.

         The Company also provides liability insurance for its directors and
officers which provides for coverage against loss from claims made against
directors and officers in their capacity as such, including liabilities under
the Securities Act of 1933, as amended. The Company or its subsidiaries have
also agreed to indemnify certain directors and officers against loss from claims
made against such persons in connection with the performance of their duties
under certain plans and agreements. Such indemnification is generally to the
same extent as provided in the Company's By-laws.

         Section 102(b)(7) of the DGCL provides that a certificate of
incorporation may contain a provision eliminating or limiting the personal
liability of a director to the corporation or its stockholders for monetary
damages for breach of fiduciary duty as a director, provided that such provision
shall not eliminate or limit the liability of a director: (i) for any breach of
the director's duty of loyalty to the corporation or its stockholders, (ii) for
acts or omissions not in good faith or which involve intentional misconduct or
knowing violation of law, (iii) under Section 174 of the DGCL, or (iv) for any
transaction from which the director derived an improper personal benefit.
Article SIXTH of the Company's Certificate of Incorporation limits the liability
of directors to the fullest extent permitted by the DGCL.

Number                Description

5.1                   Opinion of William L. Rosoff with respect to the legality
                      of the securities being registered

23.1                  Consent of Deloitte & Touche LLP

24.1                  Powers of Attorney of certain directors of the Company
                      (incorporated by reference to the Company's Annual Report
                      on Form 10-K for the year ended December 31, 2000)

24.2                  Power of Attorney for Mr. Oscar Fanjul, a director

Item 9. Undertakings.

         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 and of the estimated
         maximum offering range may be reflected in the form of prospectus filed
         with the Securities and Exchange Commission (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 (1)(i) and (1)(ii) do not apply if the
registration statement is on Form S-3, Form S-8 or Form F-3, and the information
required to be included in a post-effective amendment by those paragraphs is
contained in periodic reports filed with or furnished to the Commission by the
registrant pursuant to Section 13 or 15(d) of the Securities Exchange Act of
1934 that are incorporated by reference in the registration statement.

         (2) That, for the purpose of determining any liability under the
Securities Act of 1933, as amended, 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.

             The undersigned registrant hereby undertakes that, for
purposes of determining any liability under the Securities Act of 1933, as
amended, each filing of the registrant's annual report pursuant to Section 13(a)
or 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.

             Insofar as indemnification for liabilities arising under the
Securities Act of 1933, as amended, 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 of 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.
