Exhibit 10.12


                         MARSH & McLENNAN COMPANIES, INC
                                CANADIAN EMPLOYEE
                  1998 CASH BONUS AWARD VOLUNTARY DEFERRAL PLAN
                  ---------------------------------------------

1.         ELIGIBILITY

All active Canadian employees of Marsh & McLennan Companies, Inc. (the
"Corporation") and its subsidiaries who are designated as eligible for
participation in the MMC Partners Bonus Plan or a Local Bonus Plan, and who are
presently in salary grade 15 (or its equivalent) or above, may, at management's
discretion, be considered for participation in the Marsh & McLennan Companies,
Inc. Canadian Employee 1998 Cash Bonus Award Voluntary Deferral Plan (the "1998
Plan"). Participants in the 1998 Plan may make deferral elections pursuant to
the rules outlined in Section 2 below.

2.         PROGRAM RULES

Except as otherwise provided herein, the 1998 Plan shall be administered by the
Compensation Committee of the Board of Directors of the Corporation (the
"Committee"). The Committee shall have authority in its sole discretion to
interpret the 1998 Plan and make all determinations, including the determination
of bonus awards eligible to be deferred, with respect to the 1998 Plan. All
determinations made by the Committee shall be final and binding. The Committee
may delegate to any other individual or entity the authority to perform any or
all of the functions of the Committee under the 1998 Plan, and references to the
Committee shall be deemed to include any such delegate. Exercise of deferral
elections under the 1998 Plan must be made in accordance with the following
rules.

a.   RIGHTS TO AN AWARD AND TO A DEFERRAL ELECTION
     The right to a deferral election applies only to the annual cash bonus
     scheduled to be awarded in early 1999 in respect of 1998 services, the
     payment of which bonus would normally be made by the end of the first
     quarter of the 1999 calendar year. The granting of such an annual cash
     bonus award is discretionary, and neither delivery of deferral election
     materials nor an election to defer shall affect entitlement to such an
     award. The right to a deferral election does not apply to bonuses
     (including, but not limited to, bonuses pursuant to an employment
     agreement, sign-on or guaranteed bonuses, commissions or non-annual
     incentive payments) that are not awarded as part of an annual cash bonus
     plan.




b.   ELECTION FORMS
     In order to ensure that elections to defer bonus amounts are effective
     under applicable tax laws, please complete and sign the attached election
     form(s), and return them (postmarked or delivered) no later than December
     4, 1998. Form(s) should be returned, and any questions should be directed,
     to:

                                 William Palazzo
                     Manager, HR Systems and Administration
                        Marsh & McLennan Companies, Inc.
                           1166 Avenue of the Americas
                             New York, NY 10036-2774
                                 (212) 345-5663

c.   DEFERRAL OPTIONS

     (i) DEFERRAL AMOUNT. An eligible employee may elect to defer a portion of
     such employee's bonus award in an amount represented by one of the
     following two choices:

          1.   25%, 50%, 75% or 100% of the employee's cash bonus award, subject
               to a maximum limit established by the Committee, or

          2.   the lowest of 25%, 50%, 75% or 100% of the employee's cash bonus
               award which results in a deferral of at least Canadian $10,000.

      If the percentage selected times the amount of the cash bonus award is
      less than Canadian $10,000, NO deferral will be made or deducted from the
      award.

     (ii) PERIOD OF DEFERRAL. The payment of a bonus award may be deferred to
     January of 2000 or January 2001, as elected by the participant.

          (iii)  1998 DEFERRED BONUS ACCOUNTS. If a deferral election is made,
          deferrals may be made into one or both of the two accounts which the
          Corporation shall make available to the participating employee. The
          relevant portion of the award deferral will be credited to the
          relevant account on the first business day following the date on which
          the bonus payment would have been made had it not been deferred. The
          available accounts for deferrals of bonuses (the "1998 Deferred Bonus
          Accounts") shall consist of (a) the 1998 Putnam Fund Account and (b)
          the 1998 Interest Equivalent Account. Amounts may not be transferred
          between the 1998 Interest Equivalent Account and the 1998 Putnam Fund
          Account.




d.   1998 PUTNAM FUND ACCOUNT

     (i) ACCOUNT VALUATION. The 1998 Putnam Fund account is a bookkeeping
     account, the value of which shall be based upon the performance of selected
     funds of the Putnam mutual fund group. The Corporation will determine, in
     its sole discretion, the funds of the Putnam mutual fund group into which
     deferrals may be made. Deferrals among selected funds comprising the 1998
     Putnam Fund Account must be made in multiples of 5% of the total amounts
     deferred into the 1998 Putnam Fund Account. Deferred amounts will be
     credited to the 1998 Putnam Fund Account with units each reflecting one
     Class A share of the elected fund. Fractional units will also be credited
     to such account, if applicable. The number of such credited units will be
     determined by dividing the value of the bonus award deferred into the
     elected fund by the net asset value of such fund of the 1998 Putnam Fund
     Account as of the close of business on the day on which such bonus payment
     would have been made had it not been deferred. All dividends paid with
     respect to an elected fund of a 1998 Putnam Fund Account will be deemed to
     be immediately reinvested in such fund. All amounts credited to the 1998
     Putnam Fund Account will be converted into U.S. dollars at the exchange
     rate in effect as of the applicable date.

     (ii) FUND TRANSFERS. Amounts deferred into a 1998 Putnam Fund Account may
          be transferred between eligible funds pursuant to an election which
          may be made daily. Such election shall be effective, and the
          associated transfer shall be based upon the net asset values of the
          applicable funds of the 1998 Putnam Fund Account, as of the close of
          business on the business day the election is received by facsimile or
          mail, if received by 2:30 p.m. Eastern Time of that day. If received
          later than 2:30 p.m., the election shall be effective as of the close
          of business on the following business day.

e.    1998 INTEREST EQUIVALENT ACCOUNT
      An "Interest Equivalent" shall be calculated and added to each 1998
      Interest Equivalent Account as of the last day of each calendar quarter
      based on the average principal balance in said account during said
      calendar quarter and on the average of the 30-day Banker's Acceptance rate
      of interest as published in the Toronto Globe & Mail during such calendar
      quarter.

f.    STATEMENT OF ACCOUNT
     The Corporation shall provide periodically to each participant (but not
     less frequently than once per calendar quarter) a statement setting forth
     the balance to the credit of such participant in such participant's 1998
     Deferred Bonus Accounts.

g.    IRREVOCABILITY AND ACCELERATION

     All deferral elections made under the 1998 Plan are irrevocable. However,
     the Committee may, in its sole discretion, and upon finding that a
     participant has demonstrated severe financial hardship, direct the
     acceleration of the payment of any or all deferred amounts then credited to
     the participant's 1998 Deferred Bonus Accounts.




h.   PAYMENT OF DEFERRED AMOUNTS

     (i) DEFERRAL YEAR DISTRIBUTIONS. If the participant remains employed until
     the deferral year elected, all amounts in the participant's 1998 Deferred
     Bonus Accounts will be paid in a single distribution, less applicable
     withholding taxes, in January of the deferral year elected.

     (ii) TERMINATION OF EMPLOYMENT PRIOR TO END OF DEFERRAL PERIOD. In the
     event of termination of employment for any reason prior to the completion
     of the elected deferral period, all amounts then in the participant's 1998
     Deferred Bonus Accounts will be paid to the participant (or the
     participant's designated beneficiary in the event of death) in a single
     distribution, less applicable withholding taxes, as soon as practicable
     after the end of the quarter in which the termination occurred; PROVIDED,
     HOWEVER, that upon a participant's retirement or termination for disability
     prior to completion of the elected deferral period, all such amounts shall
     be paid in a single distribution during January of the year following such
     retirement or termination for disability, as the case may be.

     (iii)CHANGE IN CONTROL. Notwithstanding any other provision in the 1998
     Plan to the contrary, in the event of a "change in control" of the
     Corporation, as defined in the Corporation's 1997 Employee Incentive and
     Stock Award Plan, all amounts credited to a participant's 1998 Deferred
     Bonus Accounts as of the effective date of such change in control will be
     distributed within five days of such change in control as a single
     distribution, less applicable withholding taxes.

     (iv) FORM OF PAYMENT. All payments under the 1998 Plan shall be made in
     cash in Canadian dollars converted, if necessary, at the exchange rate in
     effect as of the applicable date.

i.   TAX TREATMENT
     Under present Canadian tax law, all amounts of an employee's bonus deferred
     for a period not exceeding three years from the year in which the related
     service was rendered, as well as any Interest Equivalent thereon, will be
     exempt from Canadian taxation during the period of deferral. When any part
     of the 1998 Deferred Bonus Accounts is actually paid to a participant,
     taxable employment income will be incurred.




j.   BENEFICIARY DESIGNATION

     Each participant shall have the right, at any time, to designate any person
     or persons as beneficiary or beneficiaries (both principal and contingent)
     to whom payment shall be made under the 1998 Plan and every other Cash
     Bonus Award Voluntary Deferral Plan for which the participant has or will
     have an account balance (collectively, including the 1998 Plan, the
     "Plans"), in the event of death prior to complete distribution to the
     participant of the amounts due under the Plans. Any beneficiary designation
     may be changed by a participant by the filing of such change in writing on
     a form prescribed by the Corporation. The filing of a new beneficiary
     designation form will cancel all beneficiary designations previously filed
     and apply to all deferrals in the account. A beneficiary designation form
     is attached for use by a participant who either does not have such form on
     file or wishes to make a change in the beneficiary designation. Upon
     completion of the attached form, it should be forwarded to William Palazzo,
     at the address set forth in Section 2.b. above. If a participant does not
     have a beneficiary designation in effect, or if all designated
     beneficiaries predecease the participant, then any amounts payable to the
     beneficiary shall be paid to the participant's estate. The payment to the
     designated beneficiary or to the participant's estate shall completely
     discharge the Corporation's obligations under the Plans.

3.   AMENDMENT AND TERMINATION OF THE 1998 PLAN

The Committee may, at its discretion and at any time, amend the 1998 Plan in
whole or in part. The Committee may also terminate the 1998 Plan in its entirety
at any time and, upon any such termination, each participant shall be paid in a
single distribution, or over such period of time as determined by the Committee
(provided such period of time falls within the restriction set forth in Section
2.c. (ii) above), the then remaining balance in such participant's 1998 Deferred
Bonus Accounts.

4.    MISCELLANEOUS

A participant under the 1998 Plan is merely a general (not secured) creditor,
and nothing contained in the 1998 Plan shall create a trust of any kind or a
fiduciary relationship between the Corporation and the participant or the
participant's estate. Nothing contained herein shall be construed as conferring
upon the participant the right to continued employment with the Corporation or
its subsidiaries, or to a cash bonus award. Except as otherwise provided by
applicable law, benefits payable under the 1998 Plan may not be assigned or
hypothecated, and no such benefits shall be subject to legal process or
attachment for the payment of any claim of any person entitled to receive the
same. The adoption of the 1998 Plan and any elections made pursuant to the 1998
Plan are subject to approval of the 1998 Plan by the Committee.
