Executive Annuity Agreement
                           
      Executive Annuity Agreement dated as of January 27, 1997, by and between
Merrill Lynch & Co., Inc. ("ML & Co.") and David H. Komansky (the "Executive").
 
      WHEREAS, the Executive has worked for ML & Co. for an extended period and
is at present the Chief Executive Officer of ML & Co.; and
 
      WHEREAS, ML & Co. desires to establish an incentive for the Executive,
based on the Executive's compensation and total period of qualifying service, to
continue to serve in the above-referenced position with ML & Co., or in such
other high senior executive position as the Board of Directors of ML & Co. may
hereafter specify, until such time as the Executive retires from ML & Co.;
 
      WHEREAS, the Executive's substantial expertise and knowledge relating to
the operation of the activities of ML & Co. and its affiliates is such that ML &
Co. desires that the Executive not compete with ML & Co. and its affiliates in
certain respects following the Executive's retirement from ML & Co.; and
 
      WHEREAS, in view of the foregoing ML & Co. has decided that an appropriate
benefit for the Executive, conditioned on continuing executive service until
retirement and non-competition after retirement, would be to provide the
Executive, and the Executive's surviving spouse, if any, with a retirement
annuity which supplements retirement benefits otherwise payable to the Executive
and the Executive's surviving spouse; and
 
      WHEREAS, the Executive is willing to enter into this Agreement;
 
      NOW THEREFORE, in consideration of the foregoing and the Executive's
further service with ML & Co., ML & Co. and the Executive agree as follows:

                                    SECTION 2

                                    SECTION 3
 
                                     Amount
 
      Except as otherwise provided in Section 6, the amount of the Executive
Annuity to or in respect of the Executive shall be an annual sum equal to 1.25%
of the Executive's Compensation multiplied by the Executive's Service, reduced
by the Executive's Qualified Retirement Annuity. Notwithstanding the foregoing,
however, the sum of the amount payable annually to or in respect of the
Executive under this Agreement shall not exceed (i) $1,620,000, if the
Executive's Executive Annuity is payable as a Life Annuity, or a 10-year Certain
and Life Annuity as referred to in Section 4, or (ii) $1,370,000, if the
Executive's Executive Annuity is payable as a 50% or 100% Joint and Survivor
Life Annuity as referred to in Section 4, in either case less the amount of the
Executive's Qualified Retirement Annuity.
 
      The $1,620,000 and $1,370,000 limits established under the preceding
paragraph shall be adjusted as of each December 31 and June 30 prior to the
earlier of the Executive's Retirement or death by multiplying the respective
amount by a fraction,
 
 
                                      -4-
<PAGE>
 
the numerator of which is the Index Value as of the relevant date and the
denominator of which is the Initial Index Value; provided that no adjustment
shall be made as of any December 31 or June 30 if such adjustment would result
in a decrease in the limit then in effect.
 
      Following the Executive's Retirement or death, the amount of an Executive
Annuity as determined under this Section 3 will neither be increased by any cost
of living adjustments nor reduced by any such adjustments made to the Pension
Plan Annuity under the Metropolitan Contract.
 
                                    SECTION 4
 
                            Time and Forms of Payment
 
      One-twelfth of the Executive Annuity shall be payable monthly commencing
as of the Executive's Retirement Date, which shall be at the same time and in
the same form (namely, as a Life Annuity, a 50% Joint and Survivor Life Annuity,
a 100% Joint and Survivor Life Annuity, or a 10-Year Certain and Life Annuity)
as the Pension Plan Annuity under the Metropolitan Contract that is actually so
payable to or in respect of the Executive. For purposes of computing an amount
payable under this Agreement, the computation shall be made in all cases by
applying the relevant reduction factors provided for in the Metropolitan
Contract with reference to the Beneficiary, whether or not the Beneficiary is
also the Executive's beneficiary, if any, under the Metropolitan Contract.
 
      Notwithstanding the foregoing, in the event of the death of the Executive
while in Merrill Lynch employment and before Retirement, payments to the
Beneficiary, if any, shall be made as if the Executive's Retirement was on the
day before the Executive's death with the Executive having elected a 100% Joint
and Survivor Life Annuity, computed as stated in the foregoing paragraph.
 
                                    SECTION 5
 
                                 Administration
 
      The Committee is authorized in its sole and absolute discretion, without
limitation, to make all determinations which it deems necessary or advisable for
the operation of this Agreement, to construe and interpret the Agreement, to
establish such rules and to delegate such of its authority as it deems
appropriate, and to perform all other acts believed reasonable and proper in
connection with this Agreement.
 
                                    SECTION 6
 
                            Amendment and Termination
 
 
 
                                      -5-
<PAGE>
 
      ML & Co. reserves the right to amend, modify, restate, or terminate this
Agreement in whole or in part, at any time for any reason; provided, however,
that no such action shall reduce the amount of the Executive Annuity determined
under Section 3, based on the Executive's Compensation and Service as of the
effective date of such action, but with the Qualified Retirement Annuity for
purposes of the offset under Section 3 to be determined as of the Executive's
Retirement Date, or otherwise deprive the Executive or Beneficiary of any
entitlement to such Executive Annuity determined as of the effective date of
such action.
 
                                    SECTION 7
 
                                  Miscellaneous
 
7.1 Source of Payments
 
      The obligation of ML & Co. to pay the Executive Annuity shall be unfunded
and is solely an unsecured Promise by ML & Co. All monthly payments shall be
made, as and when due, from the general assets of ML & Co. ML & Co. is not
obligated to, but may, in its sole and absolute discretion, make arrangements
with banks or insurance companies, and establish special reserve, accounts or
funds, including a "grantor trust", and may make such investments as deemed
desirable, to assist in meeting its obligations under this Agreement. Any such
arrangements with their underlying assets, reserves, accounts, or funds shall at
all times remain general assets of ML & Co., subject to the claims of its
general creditors, and neither the Executive nor the Beneficiary shall have any
right, title, or interest whatsoever therein.
 
7.2 Non-Alienation
 
      No payment or right under this Agreement is subject to anticipation,
alienation, sale, transfer, assignment, pledge, encumbrance, or charge, and any
such action, shall be void and of no effect; nor are any such payments subject
to seizure, attachment, execution, garnishment, or other legal or equitable
process, or for the payment of any debts, judgments, alimony, or separate
maintenance; nor are such payments transferable by operation of law in the event
of bankruptcy, insolvency, or similar occurrence of the Executive or
Beneficiary. In the event a person who is receiving or is entitled to receive
payments under this Agreement attempts to assign, transfer, or dispose of such
payment or right, or if an attempt is made to subject said payment or right to
such process, such assignment, transfer, or disposition shall be null and void.
 
7.3 Forfeiture
 
      The Executive and the Beneficiary, in the sole discretion of the
Committee, shall forfeit any right to payments under this Agreement not yet made
in the event that the Executive, following Retirement, enters into any
employment,
 
 
 
                                      -6-
<PAGE>
 
consulting, or other relationship with any person or entity which the Committee
determines, in its sole discretion, to be in competition with Merrill Lynch.
Competition, for purposes of this section, means any involvement in any business
in the financial services industry, including, but not limited to, investment
banking, securities brokerage, securities trading, asset management, insurance,
and banking.
 
7.4 Merger, Consolidation, Sale, or Transfer of Assets
 
      In the event ML & Co. is merged or consolidated with another entity, or
all or substantially all of the assets of ML & Co. are sold or otherwise
transferred to another entity, this Agreement shall be binding upon and inure to
the benefit of the successor or transferee resulting from or of such merger,
consolidation, sale or transfer.
 
7.5 Agreement Not a Condition of Employment
 
      Nothing in this Agreement or any action taken hereunder shall be deemed or
construed as giving the Executive any right to continued employment or as
affecting the right of Merrill Lynch to discipline (including, without
limitation, the right to discharge) the Executive at any time.
 
7.6 No Trust or Fiduciary Relationship Created
 
      Nothing contained in this Agreement and no action taken pursuant to the
provisions of this Agreement shall create or be construed to create a trust of
any kind or a fiduciary relationship between Merrill Lynch, the Executive, or
any Beneficiary.
 
7.7 Application for Payments
 
      An application for payments under this Agreement shall be in a form
acceptable to the Committee. The Committee may require any applicant to furnish
the Committee with such documented evidence or information as the Committee may
consider reasonably necessary or desirable.
 
7.8 Claims Procedure
 
      (a)   If an application for payments under this Agreement is denied, in
            whole or in part, the Committee shall promptly give the applicant
            written notice of the denial, setting forth the specific reasons
            therefor. The notice shall include the following:
 
            (i)   The basis for the denial;

            shall be delivered in writing to any member of the Committee. After
            the Committee has reviewed the application, the final decision of
            the Committee shall be communicated in writing to the applicant.
            Such communication shall set forth the specific reasons for the
            decision with reference to each appropriate Agreement provision.
 
7.9 Payments to Incompetents
 
      If the Committee receives evidence satisfactory to it that the Executive
or Beneficiary entitled to receive any payment under this Agreement is, at the
time when such payment becomes payable, physically or mentally incompetent to
receive such payment and to give a valid release therefor and that another
person or institution is then maintaining or has custody of the Executive or
Beneficiary, and that no guardian, committee, or other representative of the
estate of the Executive or Beneficiary shall have been duly appointed, the
Committee may direct payment of such payment otherwise payable to the Executive
or Beneficiary to such other person or institution, and the release of such
other person or institution shall be a valid and complete discharge for the
payments.
 
7.10 Governing Law and Exclusive Venue
 
      This Agreement shall be construed, performed and enforced under the laws
of the State of New York, without giving effect to its conflict of laws rules,
except to the extent such laws are pre-empted by Federal law. The venue with
respect to any litigation involving the Agreement and a claimant shall lie
exclusively in either (a) the Supreme Court of the State of New York, New York
County, or (b) the United States District Court for the Southern District of New
