                           MERRILL LYNCH & CO., INC.
 
  Merrill Lynch & Co., Inc. is a holding company that, through its
subsidiaries and affiliates, provides investment, financing, insurance, and
related services on a global basis. Its principal subsidiary, MLPF&S, one of
the largest securities firms in the world, is a leading broker in securities,
options contracts, and commodity and financial futures contracts; a leading
dealer in options and in corporate and municipal securities; a leading
investment banking firm that provides advice to, and raises capital for, its
clients; and an underwriter of selected insurance products. Other subsidiaries
provide financial services on a global basis similar to those of MLPF&S and
are engaged in such other activities as international banking, lending, and
providing other investment and financing services. Merrill Lynch International
Incorporated, through subsidiaries and affiliates, provides investment,
financing, and related services outside the United States and Canada. Merrill
Lynch Asset Management, LP and Fund Asset Management, LP together constitute
one of the largest mutual fund managers in the world and provide investment
advisory services. Merrill Lynch Government Securities Inc. is a primary
dealer in obligations issued or guaranteed by the U.S. Government and its
agencies. Merrill Lynch Capital Services, Inc., Merrill Lynch Derivative
Products AG, and Merrill Lynch Capital Markets PLC are the Company's primary
derivative product dealers and enter into interest rate and currency swaps and
other derivative transactions as intermediaries and as principals. The
Company's insurance underwriting operations consist of the underwriting of
life insurance and annuity products. Banking, trust, and mortgage lending
operations conducted through subsidiaries of the Company include issuing
certificates of deposit, offering money market deposit accounts, making
secured loans, and providing currency exchange trading facilities and other
related services.
 
  The principal executive office of the Company is located at World Financial
Center, North Tower, 250 Vesey Street, New York, New York 10281; its telephone
number is (212) 449-1000.
 
                                USE OF PROCEEDS
 
  The Company intends to use the net proceeds from the sale of the Securities
for general corporate purposes. Such uses may include the funding of
investments in, or extensions of credit to, its subsidiaries, the funding of
assets held by the Company or its subsidiaries, including securities
inventories, customer receivables and loans (including business loans, home
equity loans and loans in connection with investment banking-related merger
and acquisition activities) and the lengthening of the average maturity of the
Company's borrowings (including the refunding of maturing indebtedness). The
precise amount and timing of investments in, and extensions of credit to, its
subsidiaries will depend upon their funding requirements and the availability
of other funds to the Company and its subsidiaries. Pending such applications,
the net proceeds will be temporarily invested or applied to the reduction of
short-term indebtedness. A substantial portion of the proceeds from the sale
of any Currency Warrants or Index Warrants may be used to hedge market risks
with respect to such Warrants. Management of the Company expects that it will,
on a recurrent basis, engage in additional financings as the need arises to
finance the growth of the Company or to lengthen the average maturity of its
borrowings. To the extent that Securities being purchased for resale by MLPF&S
are not resold, the aggregate proceeds to the Company and its subsidiaries
would be reduced.

Senior Debt Securities will have terms and conditions identical in all
material respects to the above-referenced Senior Indentures and any Subsequent
Indenture relating to Subordinated Debt Securities will have terms and
conditions identical in all material respects to the above-referenced
Subordinated Indenture, including, but not limited to, the applicable terms
and conditions described below. Any Subsequent Indenture relating to a series
of Debt Securities, and the trustee with respect thereto, will be identified
in the applicable Prospectus Supplement. The Senior Indentures, the
Subordinated Indenture and any Subsequent Indentures (whether senior or
subordinated) are referred to herein as the "Indentures"; and the Senior Debt
Trustees, the Subordinated Debt Trustee and any Subsequent Trustees are
referred to herein as the "Trustees". A copy of each Indenture is filed (or,
in the case of a Subsequent Indenture, will be filed) as an exhibit to the
registration statements relating to the Securities (collectively, the
"Registration Statement"). The following summaries of certain provisions of
the Indentures do not purport to be complete and are subject to, and are
qualified in their entirety by reference to, all provisions of the respective
Indentures, including the definitions therein of certain terms.
 
GENERAL
 
  Each Indenture provides that Debt Securities (Senior Debt Securities in the
case of the Senior Indentures or a Subsequent Indenture for Senior Debt
Securities, and Subordinated Debt Securities in the case of the Subordinated
Indenture or a Subsequent Indenture for Subordinated Debt Securities) may be
issued thereunder, without limitation as to aggregate principal amount, in one
or more series, by the Company from time to time upon satisfaction of certain
conditions precedent, including the delivery by the Company to the applicable
Trustee of a resolution of the Board of Directors, or the Executive Committee
thereof, of the Company which fixes or provides for the establishment of terms
of such Debt Securities, including: (1) the aggregate principal amount of such
Debt Securities and whether there is any limit upon the aggregate principal
amount of such Debt Securities that may be subsequently issued; (2) the date
on which such Debt Securities will mature; (3) the principal amount payable
with respect to such Debt Securities whether at maturity or upon earlier
acceleration,
 
                                       4
<PAGE>
 
and whether such principal amount will be determined with reference to an
index, formula or other method; (4) the rate or rates per annum (which may be
fixed or variable) at which such Debt Securities will bear interest, if any;
(5) the dates on which such interest, if any, will be payable; (6) the
provisions for redemption of such Debt Securities, if any, the redemption
price and any remarketing arrangements relating thereto; (7) the sinking fund
requirements, if any, with respect to such Debt Securities; (8) whether such
Debt Securities are denominated or provide for payment in United States
dollars or a foreign currency or units of two or more of such foreign
currencies; (9) the form (registered or bearer or both) in which such Debt
Securities may be issued and any restrictions applicable to the exchange of
one form for another and to the offer, sale and delivery of such Debt
Securities in either form; (10) whether and under what circumstances the
Company will pay additional amounts ("Additional Amounts") in respect of such
Debt Securities held by a person who is not a U.S. person (as defined in the
Prospectus Supplement, as applicable) in respect of specified taxes,
assessments or other governmental charges and whether the Company has the
option to redeem the affected Debt Securities rather than pay such Additional
Amounts; (11) whether such Debt Securities are to be issued in global form;
(12) the title of the Debt Securities and the series of which such Debt
Securities shall be a part; (13) the denominations of such Debt Securities and
(14) whether, and the terms and conditions relating to when, the Company may
satisfy certain of its obligations with respect to such Debt Securities with
regard to payment upon maturity, or any redemption or required repurchase or
in connection with any exchange provisions by delivering to the Holders
thereof securities (whether or not issued by, or the obligation of, the
Company) or a combination of cash, other securities and/or property. Reference
is made to the Prospectus Supplement for the terms of the Debt Securities
being offered thereby, including whether such Debt Securities are Senior Debt
Securities or Subordinated Debt Securities. The Company may elect to deliver
to purchasers of Securities a Terms Sheet instead of a Prospectus. This
Prospectus may be delivered prior to or concurrently with a Terms Sheet. Debt
Securities may also be issued under the Indentures upon the exercise of Debt
Warrants. See "Description of Debt Warrants". Nothing in the Indentures or in
the terms of the Debt Securities will prohibit the issuance of securities
representing subordinated indebtedness that is senior or junior to the
Subordinated Debt Securities.
 
  The Debt Securities will be issued, to the extent provided in the Prospectus
Supplement, in fully registered form without coupons, and/or in bearer form
with or without coupons, and in denominations set forth in the Prospectus
Supplement. No service charge will be made for any registration of transfer of
registered Debt Securities or exchange of Debt Securities, but the Company may
require payment of a sum sufficient to cover any tax or other governmental
charges that may be imposed in connection therewith. Each Indenture provides
that Debt Securities issued thereunder may be issued in global form. If any
series of Debt Securities is issuable in global form, the applicable
Prospectus Supplement will describe the circumstances, if any, under which
beneficial owners of interest in any such global Debt Securities may exchange
such interests for Debt Securities of such series and of like tenor and
principal amount in any authorized form and denomination. Principal of, and
any premium, Additional Amounts and interest on, a global Debt Security will
be payable in the manner described in the applicable Prospectus Supplement.
 
  The provisions of the Indentures described above provide the Company with
the ability, in addition to the ability to issue Debt Securities with terms
different from those of Debt Securities previously issued, to "reopen" a
previous issue of a series of Debt Securities and issue additional Debt
Securities of such series.
 
  The Senior Debt Securities will be unsecured and will rank pari passu with
all other unsecured and unsubordinated indebtedness of the Company. The
Subordinated Debt Securities will be unsecured and will be subordinated to all
existing and future Senior Indebtedness (as defined below) of the Company.
Since the Company is a holding company, the right of the Company, and hence
the right of creditors of the Company (including the Holders of the Debt
Securities), to participate in any distribution of the assets of any
subsidiary upon its liquidation or reorganization or otherwise is necessarily
subject to the prior claims of creditors of the subsidiary, except to the
extent that claims of the Company itself as a creditor of the subsidiary may
be recognized. In addition, dividends, loans and advances from certain
subsidiaries, including MLPF&S, to the Company are restricted by net capital
requirements under the Exchange Act and under rules of certain exchanges and
other regulatory bodies.
 
                                       5
<PAGE>
 
  Principal and any interest, premium and Additional Amounts will be payable
in the manner, at the places and subject to the restrictions set forth in the
applicable Indenture, the Debt Securities and the Prospectus Supplement
relating thereto, provided that payment of any interest and any Additional
Amounts may be made at the option of the Company by check mailed to the
holders of registered Debt Securities at their registered addresses.
 
  Debt Securities may be presented for exchange, and registered Debt
Securities may be presented for transfer, in the manner, at the places and
subject to the restrictions set forth in the applicable Indenture, the Debt
Securities and the Prospectus Supplement relating thereto. Debt Securities in
bearer form and the coupons, if any, pertaining thereto will be transferable
by delivery. No service charge will be made for any transfer or exchange of
Debt Securities, but the Company may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith.
 
 "MERGER AND CONSOLIDATION"
 
  The Company may consolidate or merge with or into any other corporation, and
the Company may sell, lease or convey all or substantially all of its assets
to any corporation, provided that (i) the corporation (if other than the
Company) formed by or resulting from any such consolidation or merger or which
shall have received such assets shall be a corporation organized and existing
under the laws of the United States of America or a state thereof and shall
assume payment of the principal of, and any premium, Additional Amounts or
interest on, the Debt Securities and the performance and observance of all of
the covenants and conditions of the Indentures to be performed or observed by
the Company, and (ii) the Company or such successor corporation, as the case
may be, shall not immediately thereafter be in default under the Indentures.
 
 "MODIFICATION AND WAIVER"
 
  Modification and amendment of each Indenture may be effected by the Company
and the applicable Trustee with the consent of the Holders of at least 66 2/3%
in principal amount of the Outstanding Debt Securities of each series issued
pursuant to such Indenture and affected thereby, provided that no such
modification or amendment may, without the consent of the Holder of each
Outstanding Debt Security affected thereby, (a) change the Stated Maturity of,
or any installment of interest or Additional Amounts on, any Debt Security or
any premium payable on the redemption thereof, or change the Redemption Price;
(b) reduce the principal amount of, or the interest or Additional Amounts
payable on, any Debt Security or reduce the amount of principal which could be
declared due and payable prior to the Stated Maturity; (c) change the place or
currency of any payment of principal of, or any premium, interest or
Additional Amounts on, any Debt Security; (d) impair the right to institute
suit for the enforcement of any payment on or with respect to any Debt
Security; (e) reduce the percentage in principal amount of the Outstanding
Debt Securities of any series, the consent of whose Holders is required to
modify or amend such Indenture; or (f) modify the foregoing requirements or
reduce the percentage of Outstanding Debt Securities necessary to waive any
past default to less than a majority. No modification or amendment of the
Subordinated Indenture or any Subsequent Indenture for Subordinated Debt
Securities may adversely affect the rights of any Holder of Senior
Indebtedness without the consent of such Holder. Except with respect to
certain fundamental provisions, the Holders of at least a majority in
principal amount of Outstanding Debt Securities of any series may, with
respect to such series, waive past defaults under the applicable Indenture and
waive compliance by the Company with certain provisions of such Indenture.
 
 "EVENTS OF DEFAULT"
 
  Under each Indenture, the following will be Events of Default with respect
to Debt Securities of any series issued thereunder: (a) default in the payment
of any interest or Additional Amounts upon any Debt Security of that series
when due, and such default has continued for 30 days; (b) default in the
payment of any principal of or premium, if any, on any Debt Security of that
series when due; (c) default in the deposit of any sinking fund payment, when
due, in respect of any Debt Security of that series; (d) default in the
performance of any other
 
                                       6
<PAGE>
 
covenant of the Company contained in such Indenture for the benefit of such
series or in the Debt Securities of such series, and such default has
continued for 60 days after written notice as provided in such Indenture; (e)
certain events in bankruptcy, insolvency or reorganization; and (f) any other
Event of Default provided with respect to Debt Securities of that series. The
applicable Trustee or the Holders of 25% in principal amount of the
Outstanding Debt Securities of that series may declare the principal amount
(or such lesser amount as may be provided for in the Debt Securities of that
series) of all Outstanding Debt Securities of that series and the interest
accrued thereon and Additional Amounts payable in respect thereof, if any, to
be due and payable immediately if an Event of Default with respect to Debt
Securities of such series shall occur and be continuing at the time of
declaration. At any time after a declaration of acceleration has been made
with respect to Debt Securities of any series but before a judgment or decree
for payment of money due has been obtained by the applicable Trustee, the
Holders of a majority in principal amount of the Outstanding Debt Securities
of that series may rescind any declaration of acceleration and its
consequences, provided that all payments due (other than those due as a result
of acceleration) have been made and all Events of Default have been remedied
or waived. Any Event of Default with respect to Debt Securities of any series
may be waived by the Holders of a majority in principal amount of all
Outstanding Debt Securities of that series, except in a case of failure to pay
principal of or premium, if any, or interest or Additional Amounts, if any, on
any Debt Security of that series for which payment had not been subsequently
made or in respect of a covenant or provision which cannot be modified or
amended without the consent of the Holder of each Outstanding Debt Security of
such series affected.
 
  The Holders of a majority in principal amount of the Outstanding Debt
Securities of a series may direct the time, method and place of conducting any
proceeding for any remedy available to the applicable Trustee or exercising
any trust or power conferred on such Trustee with respect to Debt Securities
of such series, provided that such direction shall not be in conflict with any
rule of law or the applicable Indenture. Subject to the provisions of each
Indenture relating to the duties of the appropriate Trustee, before proceeding
to exercise any right or power under an Indenture at the direction of such
Holders, the applicable Trustee shall be entitled to receive from such Holders
reasonable security or indemnity against the costs, expenses and liabilities
which might be incurred by it in complying with any such direction.
 
  The Company will be required to furnish to each Trustee annually a statement
as to the fulfillment by the Company of all of its obligations under the
applicable Indenture.
 
SPECIAL TERMS RELATING TO THE SENIOR DEBT SECURITIES
 
 "LIMITATIONS UPON LIENS"
 
  The Senior Indentures provide that the Company may not, and may not permit
any Subsidiary to, create, assume, incur or permit to exist any indebtedness
for borrowed money secured by a pledge, lien or other encumbrance (except for
certain liens specifically permitted by the Senior Indentures) on the Voting
Stock owned directly or indirectly by the Company of any Subsidiary (other
than a Subsidiary which, at the time of incurrence of such secured
indebtedness, has a net worth of less than $3,000,000) without making
effective provision whereby the Outstanding Senior Debt Securities will be
secured equally and ratably with such secured indebtedness.
 
 "LIMITATIONS ON DISPOSITION OF VOTING STOCK OF, AND MERGER AND SALE OF ASSETS
BY, MLPF&S"
 
  The Senior Indentures provide that the Company may not sell, transfer or
otherwise dispose of any Voting Stock of MLPF&S or permit MLPF&S to issue,
sell or otherwise dispose of any of its Voting Stock, unless, after giving
effect to any such transaction, MLPF&S remains a Controlled Subsidiary
(defined in the Senior Indentures to mean a corporation more than 80% of the
outstanding shares of Voting Stock of which are owned directly or indirectly
by the Company). In addition, the Senior Indentures provide that the Company
may not permit MLPF&S to (i) merge or consolidate, unless the surviving
company is a Controlled Subsidiary, or (ii) convey or transfer its properties
and assets substantially as an entirety, except to one or more Controlled
Subsidiaries.
 
 
                                       7
<PAGE>
 
SPECIAL TERMS RELATING TO THE SUBORDINATED DEBT SECURITIES
 
  Upon any distribution of assets of the Company resulting from any
dissolution, winding up, liquidation or reorganization, payments on
Subordinated Debt Securities are to be subordinated to the extent provided in
the Subordinated Indenture in right of payment to the prior payment in full of
all Senior Indebtedness, but the obligation of the Company to make payments on
the Subordinated Debt Securities will not otherwise be affected. No payment on
Subordinated Debt Securities may be made at any time when there is a default
in the payment of any principal, premium, interest, Additional Amounts, if
any, or sinking fund of or on any Senior Indebtedness. Holders of Subordinated
Debt Securities will be subrogated to the rights of holders of Senior
Indebtedness to the extent of payments made on Senior Indebtedness upon any
distribution of assets in any such proceedings out of the distributive shares
of Subordinated Debt Securities. By reason of such subordination, in the event
of a distribution of assets upon insolvency, certain creditors of the Company
may recover more, ratably, than Holders of Subordinated Debt Securities.
 
  Senior Indebtedness is defined in the Subordinated Indenture as any payment
in respect of indebtedness of the Company for money borrowed, except for any
such indebtedness that is by its terms subordinated to or pari passu with
securities issued pursuant to the Subordinated Indenture. As of March 28,
1997, a total of approximately $64.1 billion of the Company's indebtedness
would have been Senior Indebtedness as so defined.

                         DESCRIPTION OF DEBT WARRANTS
 
  The Company may issue, together with Debt Securities, Currency Warrants or
Index Warrants or separately, Debt Warrants for the purchase of Debt
Securities. The Debt Warrants are to be issued under debt warrant agreements
(each a "Debt Warrant Agreement") to be entered into between the Company and a
bank or trust company, as debt warrant agent (the "Debt Warrant Agent"), all
as shall be set forth in the Prospectus Supplement relating to Debt Warrants
being offered thereby. A copy of the form of Debt Warrant Agreement, including
the form of warrant certificates representing the Debt Warrants (the "Debt
Warrant Certificates"), reflecting the alternative provisions to be included
in the Debt Warrant Agreements that will be entered into with respect to
particular offerings of Debt Warrants, is filed as an exhibit to the
Registration Statement. The following summaries of certain provisions of the
Debt Warrant Agreement and the Debt Warrant Certificates do not purport to be
complete and are subject to, and are qualified in their entirety by reference
to, all the provisions of the Debt Warrant Agreement and the Debt Warrant
Certificates, respectively, including the definitions therein of certain
terms.
 
GENERAL
 
  The applicable Prospectus Supplement will describe the terms of Debt
Warrants offered thereby, the Debt Warrant Agreement relating to such Debt
Warrants and the Debt Warrant Certificates representing such Debt Warrants,
including the following: (1) the designation, aggregate principal amount,
price at which such principal amount may be purchased upon exercise and terms
of the Debt Securities purchasable upon exercise of such Debt Warrants,
including whether such Debt Securities are Senior Debt Securities or
Subordinated Debt Securities, and the procedures and conditions relating to
the exercise of such Debt Warrants; (2) the designation and terms of any
related Debt Securities with which such Debt Warrants are issued, including
whether such Debt Securities are Senior Debt Securities or Subordinated Debt
Securities, the number of such Debt Warrants issued with each such Debt
Security, and the Indenture under which the Debt Securities will be issued;
(3) the date, if any, on and after which such Debt Warrants and the related
Debt Securities will be separately transferable; (4) the date on which the
right to exercise such Debt Warrants shall commence and the date on which such
right shall expire (the "Expiration Date"); (5) if the Debt Securities
purchasable upon exercise of such Debt Warrants are original issue discount
Debt Securities, a discussion of Federal income tax considerations applicable
thereto; and (6) whether the Debt Warrants represented by the Debt Warrant
Certificates will be issued in registered or bearer form, and, if registered,
where they may be transferred and registered.
 
  Debt Warrant Certificates will be exchangeable for new Debt Warrant
Certificates of different denominations and Debt Warrants may be exercised at
the corporate trust office of the Debt Warrant Agent or any other office
indicated in the Prospectus Supplement. Prior to the exercise of their Debt
Warrants, holders of Debt Warrants will not have any of the rights of Holders
of the Debt Securities purchasable upon such exercise and will not be entitled
to payments of principal of, and any premium, Additional Amounts, if any, or
interest on, the Debt Securities purchasable upon such exercise.
 
EXERCISE OF DEBT WARRANTS
 
  Each Debt Warrant will entitle the Holder to purchase for cash such
principal amount of Debt Securities at such exercise price as shall in each
case be set forth in, or be determinable as set forth in, the Prospectus
Supplement relating to the Debt Warrants offered thereby. Debt Warrants may be
exercised at any time up to the close of business on the Expiration Date set
forth in the Prospectus Supplement relating to the Debt Warrants offered
thereby. After the close of business on the Expiration Date, unexercised Debt
Warrants will become void.
 
  Debt Warrants may be exercised as set forth in the Prospectus Supplement
relating to the Debt Warrants offered thereby. Upon receipt of payment and the
Debt Warrant Certificate properly completed and duly executed at the corporate
trust office of the Debt Warrant Agent or any other office indicated in the
Prospectus Supplement, the Company will, as soon as practicable, forward the
Debt Securities purchasable upon such exercise. If less than all of the Debt
Warrants represented by such Debt Warrant Certificate are exercised, a new
Debt Warrant Certificate will be issued for the remaining amount of Debt
Warrants.

                       DESCRIPTION OF CURRENCY WARRANTS
 
  The Company may issue, together with Debt Securities, Debt Warrants or Index
Warrants or separately, Currency Warrants either in the form of Currency Put
Warrants entitling the Holders thereof to receive from the Company the cash
settlement value in U.S. dollars of the right to sell a specified amount of a
specified foreign currency or currency units for a specified amount of U.S.
dollars, or in the form of Currency Call Warrants entitling the Holders
thereof to receive from the Company the cash settlement value in U.S. dollars
of the right to purchase a specified amount of a specified foreign currency or

Currency Warrants are to be issued under a currency put warrant agreement or a
currency call warrant agreement, as applicable (each a "Currency Warrant
Agreement"), to be entered into between the Company and a bank or trust
company, as currency warrant agent (the "Currency Warrant Agent"), all as
shall be set forth in the applicable Prospectus Supplement. Copies of the
forms of Currency Put Warrant Agreement and Currency Call Warrant Agreement,
including the forms of warrant certificates representing the Currency Put
Warrants and Currency Call Warrants (the "Currency Warrant Certificates"),
reflecting the provisions to be included in the Currency Warrant Agreements
that will be entered into with respect to particular offerings of Currency
Warrants, are filed as exhibits to the Registration Statement. The following
summaries of certain provisions of the Currency Warrant Agreements and the
Currency Warrant Certificates do not purport to be complete and are subject
to, and are qualified in their entirety by reference to, all the provisions of
the Currency Warrant Agreements and the Currency Warrant Certificates,
respectively, including the definitions therein of certain terms.
 
GENERAL
 
  The applicable Prospectus Supplement will describe the terms of Currency
Warrants offered thereby, the Currency Warrant Agreement relating to such
Currency Warrants and the Currency Warrant Certificates representing such
Currency Warrants, including the following: (1) whether such Currency Warrants
shall be Currency Put Warrants, Currency Call Warrants, or both; (2) the
formula for determining the cash settlement value of each Currency Warrant;
(3) the procedures and conditions relating to the exercise of such Currency
Warrants; (4) the circumstances which will cause the Currency Warrants to be
deemed to be automatically exercised; (5) any minimum number of Currency
Warrants which must be exercised at any one time, other than upon automatic
exercise; and (6) the date on which the right to exercise such Currency
Warrants shall commence and the date on which such right shall expire (the
"Expiration Date"), provided that the commencement date and the Expiration
Date may be the same date.
 
BOOK-ENTRY PROCEDURES
 
  Except as may otherwise be provided in an applicable Prospectus Supplement,
the Currency Warrants will be issued in the form of global Currency Warrant
Certificates, registered in the name of a depository or its nominee.
Beneficial owners will not be entitled to receive definitive certificates
representing Currency Warrants. Ownership of a Currency Warrant will be
recorded on or through the records of the brokerage firm or other entity that
maintains a beneficial owner's account. In turn, the total number of Currency
Warrants held by an individual brokerage firm for its clients will be
maintained on the records of the depository in the name of such brokerage firm
or its agent. Transfer of ownership of any Currency Warrant will be effected
only through the selling beneficial owner's brokerage firm.
 
EXERCISE OF CURRENCY WARRANTS
 
  Each Currency Warrant will entitle the Holder to the cash settlement value
of such Currency Warrant on the applicable Exercise Date, in each case as such
terms will be defined in the applicable Prospectus Supplement. If a Currency
Warrant has more than one exercise date and is not exercised prior to 1:30
P.M., New York City time, on the fifth New York Business Day preceding the
Expiration Date, Currency Warrants will be deemed automatically exercised.
 
                                      10
<PAGE>
 
LISTING
 
  Each issue of Currency Warrants will be listed on a national securities
exchange, subject only to official notice of issuance, as a condition of sale
of any such Currency Warrants. In the event that the Currency Warrants are
delisted from, or permanently suspended from trading on, such exchange, the
Expiration Date for such Currency Warrants will be the date such delisting or
trading suspension becomes effective and Currency Warrants not previously
exercised will be deemed automatically exercised on the business day
immediately preceding such Expiration Date. The applicable Currency Warrant
Agreement will contain a covenant of the Company not to seek delisting of the
Currency Warrants, or suspension of their trading, on such exchange.
 
                         DESCRIPTION OF INDEX WARRANTS
 
  The Company may issue from time to time Index Warrants consisting of put
warrants (the "Index Put Warrants") or call warrants (the "Index Call
Warrants"). The Index Warrants will entitle the holders to receive from the
Company a payment or delivery, subject to applicable law, determined by
reference to decreases (in the case of Index Put Warrants) or to increases (in
the case of Index Call Warrants) in the level of an index or portfolio based
on one or more equity or debt securities (including the price or yield of such
securities), any statistical measure of economic or financial performance
(including any consumer price, currency or mortgage index) or the price or
value of any commodity or any combination thereof (the "Index"). Unless
otherwise specified in the accompanying Prospectus Supplement, payments, if
any, upon exercise (or deemed exercise) of the Index Warrants will be made in
U.S. dollars. The Index Warrants will be offered on terms to be determined at
the time of sale.
 
GENERAL
 
  The applicable Prospectus Supplement will describe the Index Warrant
Agreement or Index Warrant Trust Indenture (each as defined below), as the
case may be, relating to the Index Warrants being offered thereby and the
terms of such Index Warrants, including, without limitation: (i) whether the
Index Warrants to be issued will be Index Put Warrants, Index Call Warrants or
both; (ii) the aggregate number and initial public offering price or purchase
price; (iii) the Index for such Index Warrants; (iv) whether the Index
Warrants will be deemed exercised as of a specified date or whether the Index

exercise such Index Warrants commences and the date on which such right
expires; (v) the manner in which such Index Warrants may be exercised and any
restrictions on, or other special provisions relating to, the exercise of such
Index Warrants; (vi) the minimum number, if any, of such Index Warrants
exercisable at any one time; (vii) the maximum number, if any, of such Index
Warrants that may, subject to the Company's election, be exercised by all
Index Warrantholders (or by any person or entity) on any day; (viii) any
provisions permitting an Index Warrantholder to condition an exercise notice
on the absence of certain specified changes in the level of the applicable
Index after the exercise date, any provisions permitting the Company to
suspend exercise of such Index Warrants based on market conditions or other
circumstances and any other special provision relating to the exercise of such
Index Warrants; (ix) any provisions for the automatic exercise of such Index
Warrants other than at expiration; (x) any provisions permitting the Company
to cancel such Index Warrants upon the occurrence of certain events; (xi) any
additional circumstances which would constitute an Event of Default with
respect to such Index Warrants; (xii) the method of determining (a) the
payment or delivery, if any, to be made in connection with the exercise or
deemed exercise of such Index Warrants (the "Settlement Value"), (b) the
minimum payment or delivery, if any, to be made upon expiration of such Index
Warrants (the "Minimum Expiration Value"), (c) the payment or delivery to be
made upon the exercise of any right which the Company may have to cancel such
Index Warrants and (d) the value of the Index; (xiii) in the case of Index
Warrants relating to an Index for which the trading prices of underlying
securities, commodities or rates are expressed in a foreign currency, the
method of converting amounts in the relevant foreign currency or currencies
into U.S. dollars (or such other currency or composite currency in which the
Index Warrants are payable); (xiv) the method of providing for a substitute
index or otherwise determining the payment or delivery, if any, to be made in
connection with the exercise of such Index Warrants if the Index changes or
ceases to be
 
                                      11
<PAGE>
 
made available by its publisher; (xv) the time or times at which payment or
delivery, if any, will be made in respect of such Index Warrants following
exercise or deemed exercise; (xvi) the self-regulatory organization on which
such Index Warrants will be traded, if any; (xvii) any provisions for issuing
such Index Warrants in other than book-entry form; (xviii) if such Index
Warrants are not issued in book-entry form, the place or places at which
payment or delivery on cancellation, if any, and the Minimum Expiration Value,
if any, of such Index Warrants is to be made by the Company; (xix) certain
U.S. federal income tax consequences relating to such Index Warrants; and (xx)
other specific provisions.
 
  Except as otherwise provided in the applicable Prospectus Supplement, each
issue of Index Warrants will contain the terms set forth below.
 
  The Index Warrants which are issued without a Minimum Expiration Value will
be issued under one or more index warrant agreements (each, an "Index Warrant
Agreement") to be entered into between the Company and a bank or trust
company, as warrant agent (the "Index Warrant Agent"), all as described in the
Prospectus Supplement relating to such Index Warrants. The Index Warrant Agent
will act solely as the agent of the Company under the applicable Index Warrant
Agreement and will not assume any obligation or relationship of agency or
trust for or with any Index Warrantholders. A single bank or trust company may
act as Index Warrant Agent for more than one issue of Index Warrants.
 
  The Index Warrants which are issued with a Minimum Expiration Value will be
issued under one or more index warrant trust indentures (each an "Index
Warrant Trust Indenture") to be entered into between the Company and a
corporation (or other person permitted to so act by the Trust Indenture Act of
1939, as amended from time to time (the "Trust Indenture Act")), to act as
trustee (the "Index Warrant Trustee"), all as described in the Prospectus
Supplement relative to such Index Warrants. Any Index Warrant Trust Indenture
will be qualified under the Trust Indenture Act. To the extent allowed by the
Trust Indenture Act, a single qualified corporation may act as Index Warrant
Trustee for more than one issue of Index Warrants.
 
  Forms of Index Warrant Agreement and Index Warrant Trust Indenture and the
respective global index warrant certificates related thereto are filed as
exhibits to the Registration Statement. The summaries herein of certain
provisions of the Index Warrant Agreement, the Index Warrant Trust Indenture
and global index warrant certificates do not purport to be complete and are
subject to, and are qualified in their entirety by reference to, all the
provisions of the Index Warrant Agreement, the Index Warrant Trust Indenture
and global index warrant certificates, respectively.
 
  The Company will have the right to "reopen" a previous issue of Index
Warrants and to issue additional Index Warrants of such issue without the
consent of any Index Warrantholder.
 
  The Index Warrants involve a high degree of risk, including the risk that
the Index Warrants will expire worthless except for the Minimum Expiration
Value, if any, of such Index Warrants. Investors should therefore be prepared
to sustain a total loss of the purchase price of the Index Warrants (except
for the Minimum Expiration Value, if applicable). Investors who consider
purchasing Index Warrants should be experienced with respect to options and
option transactions and reach an investment decision only after carefully
considering the suitability of the Index Warrants in light of their particular
circumstances and the information set forth below as well as additional
information contained in the Prospectus Supplement relating to such Index
Warrants.
 
  Unless otherwise provided in the Prospectus Supplement, each Index Warrant
will entitle Index Warrantholders to receive from the Company upon exercise
the Settlement Value of such Index Warrant. Certain Index Warrants issued
pursuant to an Index Warrant Trust Indenture will, if specified in the
Prospectus Supplement, entitle the Index Warrantholder to receive from the
Company, under certain circumstances specified in the Prospectus Supplement, a
payment or delivery equal to the greater of the applicable Settlement Value
and a Minimum Expiration Value of such Index Warrants. In addition, certain
Index Warrants will, if specified in the Prospectus Supplement, entitle Index
Warrantholders to receive from the Company a certain payment or delivery upon
cancellation of the Index Warrants by the Company, upon the occurrence of
specified events. In addition,
 
                                      12
<PAGE>
 
if so specified in the Prospectus Supplement, following the occurrence of an
extraordinary event, the Settlement Value of an Index Warrant may, at the
option of the Company, be determined on a different basis, including in
connection with automatic exercise at expiration.
 
  Unless otherwise specified in the related Prospectus Supplement, the Index
Warrants will be deemed to be automatically exercised upon expiration or such
earlier date that may be specified. Upon such automatic exercise, Index
Warrantholders will be entitled to receive a payment or delivery equal to the
Settlement Value of the Index Warrants, except that holders of Index Warrants
having a Minimum Expiration Value will be entitled to receive a payment or
delivery equal to the greater of such Settlement Value and the applicable
Minimum Expiration Value. The Minimum Expiration Value may be either a
predetermined payment or delivery or a payment or delivery that varies during
the term of the Index Warrants in accordance with a schedule or formula. Any
Minimum Expiration Value applicable to an issue of Index Warrants, as well as
any additional circumstances resulting in the automatic exercise of such Index
Warrants, will be specified in the related Prospectus Supplement.
 
  If so specified in the Prospectus Supplement, the Index Warrants may be
canceled by the Company, or the exercise or valuation of, or payment or
delivery for, such Index Warrants may be delayed or postponed upon the
occurrence of an extraordinary event. Any extraordinary events relating to an
issue of Index Warrants will be set forth in the related Prospectus
Supplement. Upon cancellation, the related Index Warrantholders will be
entitled to receive only the applicable payment or delivery on cancellation
specified in such Prospectus Supplement. The payment or delivery on
cancellation may be either a predetermined payment or delivery or a payment or
delivery that varies during the term of the Index Warrants in accordance with
a schedule or formula.
 
  If the Company defaults with respect to any of its obligations under Index
Warrants which are issued with a Minimum Expiration Value pursuant to an Index
Warrant Trust Indenture, such default may be waived by the Index
Warrantholders of a majority in interest of all outstanding Index Warrants,
except a default in the payment or delivery of the Settlement Value, Minimum
Expiration Value or cancellation payment or delivery (if applicable) on such
Index Warrants or in respect of a covenant or provision of the applicable
Index Warrant Trust Indenture which cannot be modified or amended without the
consent of the Index Warrantholder of each outstanding Index Warrant affected.
 
  The Index Warrants are unsecured contractual obligations of the Company and
will rank pari passu with the Company's other unsecured contractual
obligations and with the Company's unsecured and unsubordinated debt. Since
the Company is a holding company, the right of the Company, and hence the
right of creditors of the Company (including the Holders of the Debt
Securities), to participate in any distribution of the assets of any
subsidiary upon its liquidation or reorganization or otherwise is necessarily
subject to the prior claims of creditors of the subsidiary, except to the
extent that claims of the Company itself as a creditor of the subsidiary may
be recognized. In addition, dividends, loans and advances from certain
subsidiaries, including MLPF&S, to the Company are restricted by net capital
requirements under the Exchange Act and under rules of certain exchanges and
other regulatory bodies.
 
  Certain special United States federal income tax considerations may be
applicable to instruments such as the Index Warrants. The related Prospectus
Supplement will describe such tax considerations. The summary of United States
Federal income tax considerations contained in the Prospectus Supplement will
be presented for informational purposes only, however, and will not be
intended as legal or tax advice to prospective purchasers. Prospective
purchasers of Index Warrants are urged to consult their own tax advisors prior
to any acquisition of Index Warrants.
 
BOOK-ENTRY PROCEDURES
 
  Except as may otherwise be provided in an applicable Prospectus Supplement,
Index Warrants will be issued in book-entry form and represented by global
Index Warrants, registered in the name of a depository or its nominee. Except
as may otherwise be provided in an applicable Prospectus Supplement, Index
Warrantholders
 
                                      13
<PAGE>
 
will not be entitled to receive definitive certificates representing Index
Warrants, unless the depository is unwilling or unable to continue as
depository or the Company decides to have the Index Warrants represented by
definitive certificates. A beneficial owner's interest in an Index Warrant
represented by a global Index Warrant will be recorded on or through the
records of the brokerage firm or other entity that maintains such beneficial
owner's account. In turn, the total number of Index Warrants held by an
individual brokerage firm or other entity for its clients will be maintained
on the records of the depository in the name of such brokerage firm or other
entity or its agent. Transfer of ownership of any Index Warrant will be
effected only through the selling beneficial owner's brokerage firm.
 
LISTING
 
  Unless otherwise indicated in the Prospectus Supplement, the Index Warrants
will be traded pursuant to the rules of a self-regulatory organization as
specified in the Prospectus Supplement. It is expected that such self-
regulatory organization will cease trading an issue of Index Warrants at the
close of business on the related expiration date of such Index Warrants.
 
MODIFICATION
 
  Any Index Warrant Agreement or Index Warrant Trust Indenture and the terms
of the related Index Warrants may be amended by the Company and the Index
Warrant Agent or Index Warrant Trustee, as the case may be (which amendment
shall take the form of a supplemental index warrant agreement or supplemental
index warrant trust indenture (collectively referred to as "Supplemental
Agreements")), without the consent of the holders of any Index Warrants, for
the purpose of (i) curing any ambiguity, or of curing, correcting or
supplementing any defective or inconsistent provision contained therein, or of
making any other provisions with respect to matters or questions arising under
the Index Warrant Agreement or Index Warrant Trust Indenture, as the case may
be, which shall not be inconsistent with the provisions thereof or of the
Index Warrants, (ii) evidencing the succession of another corporation to the
Company and the assumption by any such successor of the covenants of the
Company contained in the Index Warrant Agreement or the Index Warrant Trust
Indenture, as the case may be, and the Index Warrants, (iii) appointing a
successor depository, (iv) evidencing and providing for the acceptance of
appointment by a successor Index Warrant Agent or Index Warrant Trustee with
respect to the Index Warrants, as the case may be, (v) adding to the covenants
of the Company, for the benefit of the Index Warrantholders or surrendering
any right or power conferred upon the Company under the Index Warrant
Agreement or Index Warrant Trust Indenture, as the case may be, (vi) issuing
Index Warrants in definitive form, or (vii) amending the Index Warrant
Agreement or Index Warrant Trust Indenture, as the case may be, in any manner
which the Company may deem to be necessary or desirable and which will not
materially and adversely affect the interests of the Index Warrantholders.
 
  The Company and the Index Warrant Agent may also amend any Index Warrant
Agreement or Index Warrant Trust Indenture, as the case may be, and the terms
of the related Index Warrants (which amendment shall take the form of a
Supplemental Agreement) with the consent of the Index Warrantholders holding
not less than 66 2/3% in number of the then outstanding unexercised Index
Warrants affected by such amendment, for the purpose of adding any provisions
to or changing in any manner or eliminating any of the provisions of the Index
Warrant Agreement or Index Warrant Trust Indenture, as the case may be, or of
modifying in any manner the rights of the Index Warrantholders; provided that
no such amendment that (i) changes the determination of the Settlement Value
or the payment or delivery to be made on cancellation, if any, or Minimum
Expiration Value, if any, of the Index Warrants (or any aspects of such
determination) so as to reduce the payment or delivery to be made upon
exercise or deemed exercise, (ii) shortens the period of time during which the
Index Warrants may be exercised, or otherwise materially and adversely affects
the exercise rights of the Index Warrantholders or (iii) reduces the number of
outstanding Index Warrants, the consent of whose holders is required for
amendment of the Index Warrant Agreement, the Index Warrant Trust Indenture or
the terms of the related Index Warrants, may be made without the consent of
each Index Warrantholder affected thereby.
 
 
                                      14
<PAGE>
 
EVENTS OF DEFAULT
 
  Certain events in bankruptcy, insolvency or reorganization of the Company
will constitute an Event of Default with respect to Index Warrants having a
Minimum Expiration Value which are issued under an Index Warrant Trust
Indenture. Upon the occurrence of an Event of Default, the holders of 25% of
unexercised Index Warrants may elect to receive a settlement payment or
delivery for such unexercised Index Warrants, which will immediately become
due to the Index Warrantholders upon such election in an amount equal to the
market value of such Index Warrants (assuming the Company's ability to satisfy
its obligations under such Index Warrants as they would become due) as of the
date the Company is notified of the intended liquidation, as determined by a
nationally recognized securities broker-dealer unaffiliated with the Company
and mutually selected by the Company and the Index Warrant Trustee.
 
MERGER, CONSOLIDATION, SALE, LEASE OR OTHER DISPOSITIONS
 
  The Company may consolidate or merge with or into any other corporation and
the Company may sell, lease or convey all or substantially all of its assets
to any corporation, provided that (i) the corporation (if other than the
Company) formed by or resulting from any such consolidation or merger or which
shall have received such assets shall be a corporation organized and existing
under the laws of the United States of America or a State thereof and shall
assume the Company's obligations in respect of the payment or delivery of the
Settlement Value (or any Minimum Expiration Value or cancellation payment or
delivery, if applicable) with respect to all the unexercised Index Warrants
and the performance and observance of all of the covenants and conditions of
the Index Warrant Agreement or Index Warrant Trust Indenture, as the case may
be, to be performed or observed by the Company, and (ii) the Company or such
successor corporation, as the case may be, shall not immediately be in default
under the Index Warrant Agreement or Index Warrant Trust Indenture, as the
case may be.
 
ENFORCEABILITY OF RIGHTS BY INDEX WARRANTHOLDERS
 
  Any Index Warrantholder may, without the consent of the related Index
Warrant Agent, enforce by appropriate legal action, in and for its own behalf,
its right to exercise, and receive payment or delivery for, its Index
Warrants.
 
                             PLAN OF DISTRIBUTION
 
  The Company may sell Securities (i) through MLPF&S as agent, (ii) to the
public through, or through underwriting syndicates managed or co-managed by,
one or more underwriters, including MLPF&S, or (iii) directly to purchasers.
The Prospectus Supplement with respect to the Securities of a particular
series describes the terms of the offering of such Securities, including the
name of the agent or the name or names of any underwriters, the public
offering or purchase price, any discounts and commissions to be allowed or
paid to the agent or underwriters, all other items constituting underwriting
compensation, the discounts and commissions to be allowed or paid to dealers,
if any, and the exchanges, if any, on which the Securities will be listed.
Only the agents or underwriters so named in the Prospectus Supplement are
agents or underwriters in connection with the Securities offered thereby.
Under certain circumstances, the Company may repurchase Securities and reoffer
them to the public as set forth above. The Company may also arrange for
repurchases and resales of such Securities by dealers.
 
  If so indicated in the Prospectus Supplement, the Company will authorize
underwriters to solicit offers by certain institutions to purchase Debt
Securities from the Company pursuant to delayed delivery contracts providing
for payment and delivery on the date stated in the Prospectus Supplement. Each
such contract will be for an amount not less than, and, unless the Company
otherwise agrees, the aggregate principal amount of Debt Securities sold
pursuant to such contracts shall not be more than, the respective amounts
stated in the Prospectus Supplement. Institutions with whom such contracts,
when authorized, may be made include commercial and savings banks, insurance
companies, pension funds, investment companies, educational and charitable
institutions, and other institutions, but shall in all cases be subject to the
approval of the Company. Delayed
 
                                      15
<PAGE>
 
delivery contracts will not be subject to any conditions except that the
purchase by an institution of the Debt Securities covered thereby shall not at
the time of delivery be prohibited under the laws of any jurisdiction in the
United States to which such institution is subject.
 
  The Company has agreed to indemnify the agent and the several underwriters
against certain civil liabilities, including liabilities under the Securities
Act of 1933, as amended (the "Act"), or contribute to payments the agent or
the underwriters may be required to make in respect thereof.
 
  The distribution of Securities will conform to the requirements set forth in
the applicable sections of Rule 2720 of the Conduct Rules of the National
Association of Securities Dealers, Inc.

                                  -----------
 
  Merrill Lynch & Co., Inc. (the "Company") intends to sell from time to time
its Structured Yield Product Exchangeable for Stock(SM), STRYPES(SM). The
STRYPES will be offered to the public in series and on terms determined by
market conditions at the time of sale and set forth in the accompanying
prospectus supplement (the "Prospectus Supplement"). The STRYPES will be
unsecured obligations of the Company ranking "pari passu" with all of its other
unsecured and unsubordinated indebtedness. See "Description of the STRYPES--
Ranking".
 
  On the maturity date of each series of STRYPES (the "Maturity Date"), the
Company will pay and discharge such STRYPES by delivering to the holder thereof
a number of shares of common stock or other securities (the "Underlying
Securities") of the unaffiliated corporation identified in the Prospectus
Supplement (the "Underlying Issuer") determined in accordance with a payment
rate formula specified in the Prospectus Supplement (subject to the Company's
right to deliver cash, or a combination of cash and Underlying Securities, with
an equal value). THERE CAN BE NO ASSURANCE THAT THE VALUE OF THE UNDERLYING
SECURITIES (OR CASH) PAYABLE TO HOLDERS OF A SERIES OF STRYPES ON THE MATURITY
DATE WILL BE EQUAL TO OR GREATER THAN THE ISSUE PRICE OF SUCH STRYPES. IF THE
VALUE OF THE UNDERLYING SECURITIES (OR CASH) RECEIVED ON THE MATURITY DATE OF A
SERIES OF STRYPES IS LESS THAN THE ISSUE PRICE PAID FOR SUCH STRYPES, AN
INVESTMENT IN STRYPES WILL RESULT IN A LOSS. SEE "DESCRIPTION OF THE STRYPES".
 
  Each series of STRYPES may vary, where applicable, as to aggregate issue
price, Maturity Date, Underlying Issuer, Underlying Securities deliverable upon
maturity, formula or other method by which the amount of such Underlying
Securities will be determined, public offering or purchase price, interest rate
or rates, if any, and timing of payments thereof, provision for redemption,
currencies of denomination or currencies otherwise applicable thereto and any
other variable terms and method of distribution. The accompanying Prospectus
Supplement sets forth the specific terms with regard to the series of STRYPES
in respect of which this Prospectus is being delivered.
 
  Reference is made to any accompanying prospectus of the Underlying Issuer
covering the Underlying Securities which may be received by holders of a series
of STRYPES on the Maturity Date.

THESE SECURITIES  HAVE NOT BEEN APPROVED  OR DISAPPROVED BY THE  SECURITIES AND
 EXCHANGE COMMISSION  OR ANY STATE  SECURITIES COMMISSION NOR HAS  THE SECURI-

                           MERRILL LYNCH & CO., INC.
 
  Merrill Lynch & Co., Inc. is a holding company that, through its
subsidiaries and affiliates, provides investment, financing, insurance, and
related services on a global basis. Its principal subsidiary, MLPF&S, one of
the largest securities firms in the world, is a leading broker in securities,
options contracts, and commodity and financial futures contracts; a leading
dealer in options and in corporate and municipal securities; a leading
investment banking firm that provides advice to, and raises capital for, its
clients; and an underwriter of selected insurance products. Other subsidiaries
provide financial services on a global basis similar to those of MLPF&S and
are engaged in such other activities as international banking, lending, and
providing other investment and financing services. Merrill Lynch International
Incorporated, through subsidiaries and affiliates, provides investment,
financing, and related services outside the United States and Canada. Merrill
Lynch Asset Management, LP and Fund Asset Management, LP together constitute
one of the largest mutual fund managers in the world and provide investment
advisory services. Merrill Lynch Government Securities Inc. is a primary
dealer in obligations issued or guaranteed by the U.S. Government and its
agencies. Merrill Lynch Capital Services, Inc., Merrill Lynch Derivative
Products AG, and Merrill Lynch Capital Markets PLC are the Company's primary
derivative product dealers and enter into interest rate and currency swaps and
other derivative transactions as intermediaries and as principals. The
Company's insurance underwriting operations consist of the underwriting of
life insurance and annuity products. Banking, trust, and mortgage lending
operations conducted through subsidiaries of the Company include issuing
certificates of deposit, offering money market deposit accounts, making
secured loans, and providing currency exchange trading facilities and other
related services.
 
  The principal executive office of the Company is located at World Financial
Center, North Tower, 250 Vesey Street, New York, New York 10281; its telephone
number is (212) 449-1000.
 
                                USE OF PROCEEDS
 
  The Company intends to use the net proceeds from the sale of the STRYPES for
general corporate purposes. Such uses may include the funding of investments
in, or extensions of credit to, its subsidiaries, the funding of assets held
by the Company or its subsidiaries, including securities inventories, customer
receivables and loans (including business loans, home equity loans, and loans
in connection with investment banking-related merger and acquisition
activities), and the refunding of maturing indebtedness. The precise amount
and timing of investments in, and extensions of credit to, its subsidiaries
will depend upon their funding requirements and the availability of other
funds to the Company and its subsidiaries. Pending such applications, the net
proceeds will be temporarily invested or applied to the reduction of short-
term indebtedness. Management of the Company expects that it will, on a
recurrent basis, engage in additional financings as the need arises to finance
the growth of the Company or to lengthen the average maturity of its
borrowings. To the extent that STRYPES being purchased for resale by MLPF&S
are not resold, the aggregate proceeds to the Company and its subsidiaries
would be reduced.

                          DESCRIPTION OF THE STRYPES
 
  Each issue of STRYPES will be a series of Senior Debt Securities to be
issued under an indenture (the "1983 Indenture"), dated as of April 1, 1983,
as amended and restated, between the Company and The Chase Manhattan Bank,
formerly known as Chemical Bank (successor by merger to Manufacturers Hanover
Trust Company), as trustee (the "Trustee"), as further amended and
supplemented by a supplemental indenture to be entered into by the Company and
the Trustee relating to each series of STRYPES (the "Supplemental Indenture")
(the 1983 Indenture, as so amended and supplemented by the Supplemental
Indenture with respect to each series of STRYPES, the "Indenture"). The
following summary of certain provisions of the Indenture does not purport to
be complete and is qualified in its entirety by reference to the Indenture.
All capitalized terms not otherwise defined herein have the meanings specified
in the Indenture. Whenever defined terms of the Indenture are referred to
herein, such defined terms are incorporated by reference herein.
 
GENERAL
 
  The Supplemental Indenture will provide that STRYPES of the related series
may be issued from time to time under the Indenture, up to a specified
aggregate issue price, upon satisfaction of certain conditions precedent. The
Supplemental Indenture will establish the terms of the related series of
STRYPES, including: (1) the issue price per STRYPES; (2) the date on which
such STRYPES will mature; (3) the consideration deliverable or payable with
respect to such STRYPES, whether at maturity or upon earlier acceleration, and
the formula or other method by which the amount of such consideration will be
determined; (4) the rate or rates per annum (which may be fixed or variable)
at which such STRYPES will bear interest, if any; (5) the dates on which such
interest, if any, will be payable; (6) the provisions for redemption of such
STRYPES, if any, the redemption price and any remarketing arrangements
relating thereto; (7) the sinking fund requirements, if any, with respect to
such STRYPES; (8) whether such STRYPES are denominated or provide for payment
in United States dollars or a foreign currency or units of two or more of such
foreign currencies; (9) whether and under what circumstances the Company will
pay additional amounts ("Additional Amounts") in respect of such STRYPES held
by a person who is not a U.S. person (as defined in the Prospectus Supplement,
as applicable) in respect of specified taxes, assessments or other
governmental charges and whether the Company has the option to redeem the
affected STRYPES rather than pay such Additional Amounts; (10) the title of
the STRYPES and the series of which such STRYPES shall be a part; and (11) the
obligation of the Company to pay and discharge such STRYPES at maturity by
delivery of Underlying Securities (or, cash, or a combination of cash and
Underlying Securities, with an equal value), the formula or other method by
which the amount of such Underlying Securities will be determined, and the
terms and conditions upon which such payment and discharge shall be effected.
Reference is made to the Prospectus Supplement for the terms of the STRYPES
being offered thereby.
 
  Under the Indenture, the Company will have the ability, in addition to the
ability to issue STRYPES with terms different from those of STRYPES previously
issued, to "reopen" a previous series of STRYPES and issue additional STRYPES
of such series.
 
  Issue price and interest, premium and Additional Amounts, if any, and
Underlying Securities will be payable or deliverable in the manner, at the
places and subject to the restrictions set forth in the Indenture, the STRYPES
and the Prospectus Supplement relating thereto, provided that payment of any
interest and any Additional Amounts may be made at the option of the Company
by check mailed to the holders of registered STRYPES at their registered
addresses.
 
  STRYPES may be presented for exchange, and registered STRYPES may be
presented for transfer, in the manner, at the places and subject to the
restrictions set forth in the Indenture, the STRYPES and the Prospectus
Supplement relating thereto. No service charge will be made for any transfer
or exchange of STRYPES, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith.
 
 
                                       5
<PAGE>
 
RANKING
 
  The STRYPES will be unsecured obligations and will rank "pari passu" with all
other unsecured and unsubordinated indebtedness of the Company. Since the
Company is a holding company, the right of the Company, and hence the right of
creditors of the Company (including the holders of the STRYPES), to
participate in any distribution of the assets of any subsidiary upon its
liquidation or reorganization or otherwise is necessarily subject to the prior
claims of creditors of the subsidiary, except to the extent that claims of the
Company itself as a creditor of the subsidiary may be recognized. In addition,
dividends, loans and advances from certain subsidiaries, including MLPF&S, to
the Company are restricted by net capital requirements under the Exchange Act
and under rules of certain exchanges and other regulatory bodies.
 
SECURITIES DEPOSITORY
 
  Upon issuance, each series of STRYPES will be represented by one or more
fully registered global securities (the "Global Notes"). Each such Global Note
will be deposited with, or on behalf of, The Depository Trust Company, as
Securities Depository (the "Securities Depository"), and registered in the
name of the Securities Depository or a nominee thereof. Unless and until it is
exchanged in whole or in part for STRYPES in definitive form under the limited
circumstances described below, no Global Note may be transferred except as a
whole by the Securities Depository to a nominee of such Securities Depository
or by a nominee of such Securities Depository to such Securities Depository or
another nominee of such Securities Depository or by such Securities Depository
or any such nominee to a successor of such Securities Depository or a nominee
of such successor.
 
  The Securities Depository has advised the Company as follows: The Securities
Depository is a limited-purpose trust company organized under the Banking Law
of the State of New York, a member of the Federal Reserve System, a "clearing
corporation" within the meaning of the New York Uniform Commercial Code, and a
"clearing agency" registered pursuant to the provisions of Section 17A of the
Exchange Act. The Securities Depository was created to hold securities of its
participants ("Participants") and to facilitate the clearance and settlement
of securities transactions among its Participants in such securities through
electronic book-entry changes in accounts of the Participants, thereby
eliminating the need for physical movement of securities certificates. The
Securities Depository's Participants include securities brokers and dealers
(including MLPF&S), banks, trust companies, clearing corporations, and certain
other organizations.
 
  The Securities Depository is owned by a number of Participants and by the
New York Stock Exchange, Inc., the American Stock Exchange, Inc. and the
National Association of Securities Dealers, Inc. Access to the Securities
Depository's book-entry system is also available to others, such as banks,
brokers, dealers and trust companies that clear through or maintain a
custodial relationship with a Participant, either directly or indirectly
("Indirect Participants").
 
  Purchases of STRYPES must be made by or through Participants, which will
receive a credit on the records of the Securities Depository. The ownership
interest of each actual purchaser of each STRYPES ("Beneficial Owner") is in
turn to be recorded on the Participants' or Indirect Participants' records.
Beneficial Owners will not receive written confirmations from the Securities
Depository of their purchase, but Beneficial Owners are expected to receive
written confirmation providing details of the transaction, as well as periodic
statements of their holdings, from the Participant or Indirect Participant
through which the Beneficial Owner entered into the transaction. Ownership of
beneficial interest in such Global Note will be shown on, and the transfer of
such ownership interests will be effected only through, records maintained by
the Securities Depository (with respect to interests of Participants) and on
the records of Participants (with respect to interests of persons held through
Participants). The laws of some states may require that certain purchasers of
securities take physical delivery of such securities in definitive form. Such
limits and such laws may impair the ability to own, transfer or pledge
beneficial interests in Global Notes.
 
  "So long as the Securities Depository, or its nominee, is the registered
owner of a Global Note, the Securities Depository or its nominee, as the case
may be, will be considered the sole owner or holder of the STRYPES"
 
                                       6
<PAGE>
 
"represented by such Global Note for all purposes under the Indenture. Except
as provided below, Beneficial Owners in a Global Note will not be entitled to
have the STRYPES represented by such Global Notes registered in their names,
will not receive or be entitled to receive physical delivery of the STRYPES in
definitive form and will not be considered the owners or holders thereof under
the Indenture. Accordingly, each Person owning a beneficial interest in a
Global Note must rely on the procedures of the Securities Depository and, if
such Person is not a Participant, on the procedures of the Participant through
which such Person owns its interest, to exercise any rights of a holder under
the Indenture." The Company understands that under existing industry practices,
in the event that the Company requests any action of holders or that an owner
of a beneficial interest in such a Global Note desires to give or take any
action which a holder is entitled to give or take under the Indenture, the
Securities Depository would authorize the Participants holding the relevant
beneficial interests to give or take such action, and such Participants would
authorize Beneficial Owners owning through such Participants to give or take
such action or would otherwise act upon the instructions of Beneficial Owners.
Conveyance of notices and other communications by the Securities Depository to
Participants, by Participants to Indirect Participants, and by Participants
and Indirect Participants to Beneficial Owners will be governed by
arrangements among them, subject to any statutory or regulatory requirements
as may be in effect from time to time.
 
  Payment of any amount with respect to STRYPES registered in the name of the
Securities Depository or its nominee will be made to the Securities Depository
or its nominee, as the case may be, as the holder of the Global Notes
representing such STRYPES. None of the Company, the Trustee or any other agent
of the Company or agent of the Trustee will have any responsibility or
liability for any aspect of the records relating to or payments made on
account of beneficial ownership interests or for supervising or reviewing any
records relating to such beneficial ownership interests. The Company expects
that the Securities Depository, upon receipt of any payment in respect of a
Global Note, will credit the accounts of the Participants with payment in
amounts proportionate to their respective holdings of beneficial interest in
such Global Note as shown on the records of the Securities Depository. The
Company also expects that payments by Participants to Beneficial Owners will
be governed by standing customer instructions and customary practices, as is
now the case with securities held for the accounts of customers in bearer form
or registered in "street name", and will be the responsibility of such
Participants.
 
  If, with respect to a series of STRYPES, (x) the Securities Depository is at
any time unwilling or unable to continue as Securities Depository and a
successor depository is not appointed by the Company within 60 days, (y) the
Company executes and delivers to the Trustee a Company Order to the effect
that the Global Notes shall be exchangeable or (z) an Event of Default has
occurred and is continuing with respect to any STRYPES of that series, the
Company will issue STRYPES in definitive form in exchange for all of the
Global Notes representing the STRYPES of that series. Such definitive STRYPES
shall be registered in such name or names as the Securities Depository shall
instruct the Trustee. It is expected that such instructions may be based upon
directions received by the Securities Depository from Participants with
respect to ownership of beneficial interests in such Global Notes.
 
MERGER AND CONSOLIDATION
 
  The Company may consolidate or merge with or into any other corporation, and
the Company may sell, lease or convey all or substantially all of its assets
to any corporation, provided that (i) the corporation (if other than the
Company) formed by or resulting from any such consolidation or merger or which
shall have received such assets shall be a corporation organized and existing
under the laws of the United States of America or a state thereof and shall
assume the due and punctual delivery or payment of the Underlying Securities
(or cash with an equal value) in respect of, any interest and Additional
Amounts on, and any other amounts payable with respect to, the STRYPES of each
series and the due and punctual performance and observance of all of the
covenants and conditions of the Indenture to be performed or observed by the
Company, and (ii) the Company or such successor corporation, as the case may
be, shall not immediately thereafter be in default under the Indenture.

LIMITATIONS UPON LIENS
 
  The Indenture provides that the Company may not, and may not permit any
Subsidiary (defined in the Indenture as any corporation of which at the time
of determination the Company and/or one or more Subsidiaries owns or controls
directly or indirectly 50% of the shares of Voting Stock of such corporation)
to, create, assume, incur or permit to exist any indebtedness for borrowed
money secured by a pledge, lien or other encumbrance (except for certain liens
specifically permitted by the Indenture) on the Voting Stock owned directly or
indirectly by the Company of any Subsidiary (other than a Subsidiary which, at
the time of incurrence of such secured indebtedness, has a net worth of less
than $3,000,000) without making effective provision whereby the Outstanding
STRYPES will be secured equally and ratably with such secured indebtedness.
 
LIMITATIONS ON DISPOSITION OF VOTING STOCK OF, AND MERGER AND SALE OF ASSETS
BY, MLPF&S
 
  The Indenture provides that the Company may not sell, transfer or otherwise
dispose of any Voting Stock of MLPF&S or permit MLPF&S to issue, sell or
otherwise dispose of any of its Voting Stock, unless, after giving effect to
any such transaction, MLPF&S remains a Controlled Subsidiary (defined in the
Indenture to mean a corporation more than 80% of the outstanding shares of
Voting Stock of which are owned directly or indirectly by the Company). In
addition, the Indenture provides that the Company may not permit MLPF&S to (i)
merge or consolidate, unless the surviving company is a Controlled Subsidiary,
or (ii) convey or transfer its properties and assets substantially as an
entirety, except to one or more Controlled Subsidiaries.
 
EVENTS OF DEFAULT
 
  Unless otherwise specified in a Prospectus Supplement, each of the following
will constitute an Event of Default under the Indenture with respect to each
series of STRYPES: (a) failure to pay and discharge the STRYPES of that series
with the Underlying Securities or, if the Company so elects, to pay an
equivalent amount in cash in lieu thereof when due; (b) failure to pay the
Redemption Price or any redemption premium with respect to any STRYPES of that
series when due; (c) failure to deposit any sinking fund payment, when and as
due by the terms of any STRYPES of that series; (d) failure to pay any
interest on or any Additional Amounts in respect of any STRYPES of that series
when due, continued for 30 days; (e) failure to perform any other covenant of
the Company contained in the Indenture for the benefit of that series or in
the STRYPES of that series, continued for 60 days after written notice has
been given to the Company by the Trustee, or to the Company and the Trustee by
the holders of at least 10% of the aggregate issue price of the Outstanding
STRYPES of that series, as provided in the Indenture; (f) certain events in
bankruptcy, insolvency or reorganization of the Company; and (g) any other
Event of Default provided with respect to STRYPES of that series.
 
  Unless otherwise specified in a Prospectus Supplement, if an Event of
Default (other than an Event of Default described in clause (f) of the
immediately preceding paragraph) with respect to the STRYPES of any series
shall occur and be continuing, either the Trustee or the holders of at least
25% of the aggregate issue price of the Outstanding STRYPES of that series by
notice as provided in the Indenture may declare an amount equal to the
aggregate issue price of all the STRYPES of that series and the interest
accrued thereon and Additional Amounts payable in respect thereof, if any, to
be immediately due and payable in cash. If an Event of Default described in
said clause (f) shall occur, an amount equal to the aggregate issue price of
all the STRYPES of that series and the interest accrued thereon and Additional
Amounts payable in respect thereof, if any, will become immediately due and
payable in cash without any declaration or other action on the part of the
Trustee or any holder. After such acceleration, but before a judgment or
decree based on acceleration, the holders of a majority of the aggregate issue
price of the Outstanding STRYPES of that series may, under certain
circumstances, rescind and annul such acceleration if all Events of Default,
other than the non-payment of the amount equal to the aggregate issue price of
all the STRYPES of that series due by reason of such acceleration, have been
cured or waived as provided in the Indenture. See "Modification and Waiver"
below.
 
  Subject to the provisions of the Indenture relating to the duties of the
Trustee, in case an Event of Default shall occur and be continuing, the
Trustee will be under no obligation to exercise any of its rights or powers
under the Indenture at the request or direction of any of the holders of
STRYPES of any series, unless such
 
                                       8
<PAGE>
 
holders of that series shall have offered to the Trustee reasonable security
or indemnity against the costs, expenses and liabilities which might be
incurred by it in compliance with such request or direction. Subject to such
provisions for the indemnification of the Trustee, the holders of a majority
of the aggregate issue price of the STRYPES of any series 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 STRYPES of that series.
 
  The Company will be required to furnish to the Trustee annually a statement
by certain of its officers as to whether or not the Company, to their
knowledge, is in default in the fulfillment of any of its obligations under
the Indenture and, if so, specifying all such known defaults.
 
  The STRYPES and other series of Senior Debt Securities issued under the
Indenture will not have the benefit of any cross-default provisions with other
indebtedness of the Company.
 
MODIFICATION AND WAIVER
 
  Unless otherwise specified in a Prospectus Supplement, modifications of and
amendments to the Indenture affecting a series of STRYPES may be made by the
Company and the Trustee with the consent of the holders of 66 2/3% of the
aggregate issue price of the Outstanding STRYPES of such series; provided,
however, that no such modification or amendment may, without the consent of
the holder of each Outstanding STRYPES of such series affected thereby, (a)
change the Maturity Date or the Stated Maturity of any installment of interest
or Additional Amounts on any STRYPES or any premium payable on the redemption
thereof, or change the Redemption Price, (b) reduce the amount of Underlying
Securities payable with respect to any STRYPES (or reduce the amount of cash,
or cash and Underlying Securities, payable in lieu thereof), (c) reduce the
amount of interest or Additional Amounts payable on any STRYPES or reduce the
amount of cash payable with respect to any STRYPES upon acceleration of the
maturity thereof, (d) change the place or currency of payment of interest or
Additional Amounts on, or any amount of cash payable with respect to, any
STRYPES, (e) impair the right to institute suit for the enforcement of any
payment on or with respect to any STRYPES, including the payment of Underlying
Securities with respect to any STRYPES, (f) reduce the percentage of the
aggregate issue price of Outstanding STRYPES of such series, the consent of
whose holders is required to modify or amend the Indenture, (g) reduce the
percentage of the aggregate issue price of Outstanding STRYPES of such series
necessary for waiver of compliance with certain provisions of the Indenture or
for waiver of certain defaults or (h) modify such provisions with respect to
modification and waiver. Except as provided in the Indenture, no modification
of or amendment to the Indenture may adversely affect the rights of a holder
of any other Senior Debt Security without the consent of such holder.
 
  The holders of a majority of the aggregate issue price of each series of
STRYPES may waive compliance by the Company with certain restrictive
provisions of the Indenture. The holders of a majority of the aggregate issue
price of each series of STRYPES may waive any past default under the
Indenture, except a default in the payment of the Underlying Securities with
respect to any STRYPES of that series, or of cash payable in lieu thereof, or
in the payment of any premium, interest or Additional Amounts on any STRYPES
of that series for which payment had not been subsequently made or in respect
of a covenant and provision of the Indenture which cannot be modified or
amended without the consent of the holder of each Outstanding STRYPES of such
series affected.
 
GOVERNING LAW
 
  The Indenture and the STRYPES will be governed by, and construed in
accordance with, the laws of the State of New York.

                             PLAN OF DISTRIBUTION
 
  The Company may sell STRYPES to the public through MLPF&S. The accompanying
Prospectus Supplement describes the terms of the STRYPES offered thereby,
including the public offering or purchase price, any discounts and commissions
to be allowed or paid, all other items constituting underwriting compensation,
the discounts and commissions to be allowed or paid to dealers, if any, and
the exchanges, if any, on which the STRYPES will be listed. Under certain
circumstances, the Company may repurchase STRYPES and reoffer them to the
public as set forth above. The Company may also arrange for repurchases and
resales of such STRYPES by dealers.
 
  The underwriting of STRYPES will conform to the requirements set forth in
the applicable sections of Rule 2720 of the Conduct Rules of the National
Association of Securities Dealers, Inc.

                   DUE NINE MONTHS OR MORE FROM DATE OF ISSUE
                                  ----------
  Merrill Lynch & Co., Inc. (the "Company") may offer from time to time up to
$              aggregate principal amount (except that with respect to Notes
sold at a discount, the initial offering price will be used), or the equivalent
thereof in one or more foreign currencies or currency units, of its Medium-Term
Notes, Series B (the "Notes"). Each Note will mature on a day nine months or
more from the date of issue, as selected by the purchaser and agreed to by the
Company, and may be subject to redemption by the Company or repayment at the
option of the Holder thereof, in each case, in whole or in part, prior to its
Stated Maturity, as set forth therein and specified in a pricing supplement
hereto (each, a "Pricing Supplement").
  The interest rate, if any, or the formula for the determination of any such
interest rate, applicable to each Note and other variable terms of the Notes as
described herein will be established by the Company at the date of issue of
such Note and will be set forth therein and specified in a Pricing Supplement.
Interest rates, interest rate formulae and such other variable terms are
subject to change by the Company, but no change will affect any Note already
issued or as to which an offer to purchase has been accepted by the Company.
Each Note will be issued in fully registered book-entry form (a "Book-Entry
Note") or certificated form (a "Certificated Note"), as set forth in the
applicable Pricing Supplement, in denominations of $1,000 and integral
multiples thereof, unless otherwise specified in the applicable Pricing
Supplement. Each Book-Entry Note will be represented by one or more global
securities ("Global Notes") deposited with or on behalf of The Depository Trust
Company (or such other depository as is identified in an applicable Pricing
Supplement) (the "Depository") and registered in the name of the Depository's
nominee. Beneficial interests in Book-Entry Notes will be shown on, and
transfers thereof will be effected only through, records maintained by the
Depository (with respect to its participants) and the Depository's participants
(with respect to Beneficial Owners). Beneficial Owners of the Book-Entry Notes
will not have the right to receive physical certificates evidencing their
ownership except under the limited circumstances described herein.
  Unless otherwise specified in an applicable Pricing Supplement, the Notes
will bear interest at fixed rates (the "Fixed Rate Notes") or at floating rates
(the "Floating Rate Notes"). The applicable Pricing Supplement will specify
whether a Floating Rate Note is a Floating Rate/Fixed Rate Note, Inverse
Floating Rate Note or Regular Floating Rate Note and whether its rate of
interest is determined by reference to one or more of the CD Rate, the CMT
Rate, the Commercial Paper Rate, the Eleventh District Cost of Funds Rate, the
Federal Funds Rate, LIBOR, the Prime Rate or the Treasury Rate, or any other
interest rate basis or formula (each, an "Interest Rate Basis"), as adjusted by
any Spread and/or Spread Multiplier and will specify such other terms
applicable to such Note. Interest rates offered by the Company with respect to
the Notes may differ depending upon the aggregate principal amount of Notes
subject to purchase in any single transaction. See "Description of Notes".

    resale to investors and other purchasers at varying prices relating to
    prevailing market prices at the time of resale as determined by the Agent,
    or, if so specified in an applicable Pricing Supplement, for resale at a
    fixed public offering price. Unless otherwise specified in an applicable
    Pricing Supplement, any Note sold to the Agent as principal will be
    purchased by such Agent at a price equal to 100% of the principal amount
    thereof less a percentage of the principal amount equal to the commission
    applicable to an agency sale (as described below) of a Note of identical
    maturity. If agreed to by the Company and the Agent, the Agent may utilize
    their reasonable efforts on an agency basis to solicit offers to purchase
    the Notes at 100% of the principal amount thereof, unless otherwise
    specified in an applicable Pricing Supplement. The Company will pay a
    commission to an Agent, ranging from .125% to .750% (or, with respect to
    Notes for which the Stated Maturity is in excess of 30 years, such
    commission as shall be agreed upon by the Company and the related Agent at
    the time of sale) of the principal amount of a Note, depending upon its
    Stated Maturity, sold through such Agent.
(2) The Company has agreed to indemnify the Agent against, and to provide
    contribution with respect to, certain liabilities, including liabilities
    under the Securities Act of 1933, as amended. See "Plan of Distribution".

                                 RISK FACTORS
 
  "This Prospectus Supplement does not describe all of the risks of an
investment in Notes that result from such Notes being denominated or payable
in or determined by reference to a currency or composite currency other than
United States dollars or to one or more interest rate, currency or other
indices or formulas. The Company and the Agent disclaim any responsibility to
advise prospective investors of such risks as they exist at the date of this
Prospectus Supplement or as they change from time to time. Prospective
investors should consult their own financial and legal advisors as to the
risks entailed by an investment in such Notes and the suitability of investing
in such Notes in light of their circumstances. Such Notes are not an
appropriate investment for investors who are unsophisticated with respect to
foreign currency transactions or transactions involving the applicable
interest rate index or currency index or other indices or formulas.
Prospective investors should carefully consider, among other factors, the
matters described below."
 
STRUCTURE RISKS
 
  An investment in Notes indexed, as to principal, premium, if any, and/or
interest, if any, to one or more currencies or composite currencies (including
exchange rates and swap indices between currencies or composite currencies),
commodities, interest rates or other indices or formulas, either directly or
inversely, entails significant risks that are not associated with similar
investments in a conventional fixed rate or floating rate debt security. Such
risks include, without limitation, the possibility that such indices or
formulas may be subject to significant changes, that no interest will be
payable in respect of such Notes or that the resulting interest rate will be
less than that payable on a conventional fixed rate or floating rate debt
security issued by the Company at the same time, that the repayment of
principal and/or premium, if any, can occur at times other than that expected
by the investor, and that the investor could lose all or a substantial portion
of principal and/or premium, if any, payable on the Maturity Date (as defined
under "Description of Notes--General"). Such risks depend on a number of
interrelated factors, including economic, financial and political events, over
which the Company has no control. Additionally, if the formula used to
determine the amount of principal, premium, if any, and/or interest, if any,
payable with respect to such Notes contains a multiplier or leverage factor,
the effect of any change in the applicable index or indices or formula or
formulas will be magnified. In recent years, values of certain indices and
formulas have been highly volatile and such volatility may be expected to
continue in the future. Fluctuations in the value of any particular index or
formula that have occurred in the past are not necessarily indicative,
however, of fluctuations that may occur in the future.
 
  Any optional redemption feature of Notes might affect the market value of
such Notes. Since the Company may be expected to redeem such Notes when
prevailing interest rates are relatively low, an investor might not be able to
reinvest the redemption proceeds at an effective interest rate as high as the
interest rate on such Notes.
 
  The Notes will not have an established trading market when issued, and there
can be no assurance of a secondary market for the Notes or the continued
liquidity of such market if one develops. See "Plan of Distribution."
 
  The secondary market, if any, for such Notes will be affected by a number of
factors independent of the creditworthiness of the Company and the value of
the applicable index or indices or formula or formulas, including the
complexity and volatility of each such index or formula, the method of
calculating the principal, premium, if any, and/or interest, if any, in
respect of such Notes, the time remaining to the maturity of such Notes, the
outstanding amount of such Notes, any redemption features of such Notes, the
amount of other debt securities linked to such index or formula and the level,
direction and volatility of market interest rates generally.
 
                                      S-2
<PAGE>
 
Such factors also will affect the market value of such Notes. In addition,
certain Notes may be designed for specific investment objectives or strategies
and, therefore, may have a more limited secondary market and experience more
price volatility than conventional debt securities. Investors may not be able
to sell such Notes readily or at prices that will enable investors to realize
their anticipated yield. No investor should purchase Notes unless such
investor understands and is able to bear the risk that such Notes may not be
readily saleable, that the value of such Notes will fluctuate over time and
that such fluctuations may be significant.
 
CREDIT RATINGS
 
  Any credit ratings assigned to the Company's medium-term note program may
not reflect the potential impact of all risks related to structure and other
factors on the market value of the Notes. Accordingly, prospective investors
should consult their own financial and legal advisors as to the risks entailed
by an investment in the Notes and the suitability of such Notes in light of
their particular circumstances.

  For the purpose of calculating the ratio of earnings to fixed charges,
"earnings" consists of earnings from continuing operations before income taxes
and fixed charges. "Fixed charges" consists of interest costs, amortization of
debt expense, preferred stock dividend requirements of majority-owned
subsidiaries, and that portion of rentals estimated to be representative of
the interest factor.

                             DESCRIPTION OF NOTES
 
  The Notes will be issued as a series of debt securities under a senior
indenture, dated as of October 1, 1993 (the "1993 Indenture"), between the
Company and The Chase Manhattan Bank (successor by merger to The Chase
Manhattan Bank, N.A.), as trustee (as used in this Prospectus Supplement, the
"Trustee"). The term "Senior Debt Securities," as used in this Prospectus
Supplement, refers to all securities issued and issuable from time to time
under the Senior Indentures (as defined in the accompanying Prospectus) and
includes the Notes. The Senior Debt Securities and the Trustee are more fully
described in the accompanying Prospectus. The following summary of certain
provisions of the Notes and of the 1993 Indenture does not purport to be
complete and is qualified in its entirety by reference to the 1993 Indenture,
a copy of which has been filed as an exhibit to the Registration Statement of
which this Prospectus Supplement and the accompanying Prospectus are a part.
Capitalized terms used but not defined herein have the meanings given to them
in the 1993 Indenture or the Notes, as the case may be.
 
  THE FOLLOWING DESCRIPTION OF NOTES WILL APPLY UNLESS OTHERWISE SPECIFIED IN
AN APPLICABLE PRICING SUPPLEMENT.
 
GENERAL
 
  All Senior Debt Securities, including the Notes, issued and to be issued
under the Senior Indentures will be unsecured general obligations of the
Company and will rank "pari passu" with all other unsecured and unsubordinated
indebtedness of the Company from time to time outstanding. However, because
the Company is a holding company, the right of the Company, and hence the
right of creditors of the Company (including the Holders of the Notes), to
participate in any distribution of the assets of any subsidiary upon its
liquidation or reorganization or otherwise is necessarily subject to the prior
claims of creditors of the subsidiary, except to the extent that claims of the
Company itself as a creditor of the subsidiary may be recognized. In addition,
dividends, loans and advances from certain subsidiaries, including Merrill
Lynch, Pierce, Fenner & Smith Incorporated, to the Company are restricted by
net capital requirements under the Securities Exchange Act of 1934, as
amended, (the "Exchange Act") and under rules of certain exchanges and other
regulatory bodies.
 
  The Senior Indentures do not limit the aggregate principal amount of Senior
Debt Securities which may be issued thereunder and Senior Debt Securities may
be issued thereunder from time to time as a single series or in two or more
separate series up to the aggregate principal amount from time to time
authorized by the Company for each series. The Company may, from time to time,
without the consent of the Holders of the Notes, provide for the issuance of
Notes or other Senior Debt Securities under the Senior Indentures in addition
to the $       aggregate principal amount of Notes offered hereby. As of March
28, 1997, the Company had issued and outstanding Notes in an aggregate
principal amount of approximately $10.3 billion. The aggregate principal
amount of Notes which may be offered hereby may be reduced by the issuance of
other securities of the Company pursuant to the registration statement of
which this Prospectus Supplement and the accompanying Prospectus are a part.
 
  The Notes will be offered on a continuing basis and will mature on a day
nine months or more from the date of issue, as selected by the purchaser and
agreed to by the Company. Interest-bearing Notes will either be Fixed Rate
Notes or Floating Rate Notes as specified in the applicable Pricing
Supplement. Notes may be issued at significant discounts from their principal
amount payable at Stated Maturity (or on any prior date on which the principal
or an installment of principal of a Note becomes due and payable, whether by
the declaration of acceleration, call for redemption at the option of the
Company, repayment at the option of the Holder or otherwise) (each such date,
a "Maturity"), and some Notes may not bear interest.
 
  Unless otherwise indicated in a Note and in the applicable Pricing
Supplement, the Notes will be denominated in United States dollars and
payments of principal of, and premium, if any, and interest on, the Notes will
be made in United States dollars. If any of the Notes to be denominated other
than in United States dollars or if the principal of, and interest on, the
Notes, and any premium provided for in any Note is to be
 
                                      S-4
<PAGE>
 
payable in or by reference to a currency (or in composite currency units or in
amounts determined by reference to one or more currencies) other than that in
which such Note is denominated, provisions with respect thereto will be set
forth in such Note and in the applicable Pricing Supplement.
 
  Interest rates, interest rate formulae and other variable terms of the Notes
are subject to change by the Company from time to time, but no such change
will affect any Note already issued or as to which an offer to purchase has
been accepted by the Company.
 
  Each Note will be issued in fully registered book-entry form (a "Book-Entry
Note") or certificated form (a "Certificated Note"), in denominations of
$1,000 and integral multiples thereof, unless otherwise specified in the
applicable Pricing Supplement. Book-Entry Notes may be transferred or
exchanged only through a participating member of The Depository Trust Company
(or such other depository as is identified in an applicable Pricing
Supplement) (the "Depository"). See "Book-Entry Notes." Registration of
transfer of Certificated Notes will be made at the Corporate Trust Office of
the Trustee. No service charge will be made by the Company, the Trustee or the
Security Registrar for any such registration of transfer or exchange of Notes,
but the Company may require payment of a sum sufficient to cover any tax or
other governmental charge payable in connection therewith (other than
exchanges pursuant to the 1993 Indenture, not involving any transfer).
 
  Payments of principal of, and premium and interest, if any, on Book-Entry
Notes will be made by the Company through the Trustee to the Depository or its
nominee. See "Book-Entry Notes." Unless otherwise specified in the applicable
Pricing Supplement, a Beneficial Owner of Book-Entry Notes denominated in a
currency other than United States dollars (a "Specified Currency") electing to
receive payments of principal or any premium or interest in such Specified
Currency must notify the Participant through which its interest is held on or
prior to the applicable Record Date, in the case of a payment of interest, and
on or prior to the sixteenth day, whether or not a Business Day (as defined
below), prior to its Stated Maturity, in the case of principal or premium, of
such Beneficial Owner's election to receive all or a portion of such payment
in a Specified Currency. Such Participant must notify the Depository of such
election on or prior to the third Business Day after such Record Date. The
Depository will notify the Paying Agent of such election on or prior to the
fifth Business Day after such Record Date. If complete instructions are
received by the Participant and forwarded by the Participant to the
Depository, and by the Depository to the Paying Agent, on or prior to such
dates, the Beneficial Owner will receive payments in the Specified Currency.
 
  In the case of Certificated Notes, payment of principal or premium, if any,
at the Maturity of each Certificated Note will be made in immediately
available funds upon presentation of the Certificated Note at the Corporate
Trust Office of the Trustee in the Borough of Manhattan, The City of New York,
or at such other place as the Company may designate. Payment of interest due
at Maturity will be made to the person to whom payment of the principal of the
Certificated Note shall be made. Payment of interest due on Certificated Notes
other than at Maturity will be made at the Corporate Trust Office of the
Trustee or, at the option of the Company, may be made by check mailed to the
address of the Person entitled thereto as such address shall appear in the
Security Register. Notwithstanding the foregoing, a Holder of $1,000,000 or
more in aggregate principal amount of Certificated Notes (whether having
identical or different terms and provisions) having the same Interest Payment
Dates will, at the option of the Company, be entitled to receive interest
payments (other than at Maturity) by wire transfer of immediately available
funds if appropriate wire transfer instructions have been received in writing
by the Trustee not less than 15 days prior to the applicable Interest Payment
Date. Any such wire instructions received by the Trustee shall remain in
effect until revoked by such Holder.
 
TRANSACTION AMOUNT
 
  Interest rates offered by the Company with respect to the Notes may differ
depending upon, among other things, the aggregate principal amount of Notes
purchased in any transaction. Notes with similar variable terms but different
interest rates may be offered concurrently at any time. The Company may also
concurrently offer Notes having different variable terms (as are described
herein or in any Prospectus Supplement) to different investors.
 
                                      S-5
<PAGE>
 
REDEMPTION AT THE OPTION OF THE COMPANY
 
  The Notes will not be subject to any sinking fund. The Notes will be
redeemable at the option of the Company prior to their Stated Maturity only if
an Initial Redemption Date is specified therein and in the applicable Pricing
Supplement. If so indicated in the applicable Pricing Supplement, Notes will
be subject to redemption at the option of the Company on any date on and after
the applicable Initial Redemption Date specified in such Pricing Supplement.
On and after the Initial Redemption Date, if any, the related Note may be
redeemed at any time in whole or from time to time in part (in increments of
$1,000, provided that any remaining principal amount shall be an authorized
denomination of the applicable Note) at the option of the Company at the
applicable Redemption Price (as defined below) together with interest thereon
payable to the Redemption Date, on notice given, unless otherwise specified in
the applicable Pricing Supplement, not more than 60 nor less than 30 days
prior to the Redemption Date. "Redemption Price" with respect to a Note will
initially mean a percentage, the Initial Redemption Percentage, of the
principal amount of such Note to be redeemed specified in the applicable
Pricing Supplement and shall decline at each anniversary of the Initial
Redemption Date by a percentage, the Annual Redemption Percentage Reduction,
if any, specified in the applicable Pricing Supplement, of the principal
amount to be redeemed until the Redemption Price is 100% of such principal
amount.
 
REPAYMENT AT THE OPTION OF THE HOLDER
 
  If so indicated in an applicable Pricing Supplement, Notes will be repayable
by the Company in whole or in part at the option of the Holders thereof on
their respective Optional Repayment Dates specified in such Pricing
Supplement. If no Optional Repayment Date is indicated with respect to a Note,
such Note will not be repayable at the option of the Holder prior to its
Stated Maturity. Any repayment in part will be in an amount equal to $1,000 or
integral multiples thereof, provided that any remaining principal amount shall
be an authorized denomination of the applicable Note. The repurchase price for
any Note so repurchased will be 100% of the principal amount to be repaid,
together with interest thereon payable to the date of repayment. For any Note
to be repaid, such Note must be received, together with the form thereon
entitled "Option to Elect Repayment" duly completed, by the Trustee at its
office maintained for such purpose in the Borough of Manhattan, The City of
New York, currently the Corporate Trust Office of the Trustee, not more than
60 nor less than 30 days prior to the Optimal Repayment Date. Notices of
elections from a Holder to exercise the repayment option must be received by
the Trustee by 5:00 p.m., New York City time, on the last day for giving such
notice. Exercise of such repayment option by the Holder will be irrevocable.
 
  While the Book-Entry Notes are represented by Global Notes held by or on
behalf of the Depository, and registered in the name of the Depository or the
Depository's nominee, the option for repayment may be exercised by the
applicable Participant (as defined below under "Book- Entry Notes") on behalf
of the Beneficial Owners (as defined below) of such Book-Entry Notes by
delivering a written notice to the Trustee at the Corporate Trust Office, not
more than 60 nor less than 30 days prior to the Optional Repayment Date.
Notices of elections from Participants on behalf of Beneficial Owners of the
Book-Entry Notes to exercise their option to have the Book-Entry Notes repaid
must be received by the Trustee by 5:00 p.m., New York City time, on the last
day for giving such notice. In order to ensure that a notice is received by
the Trustee on a particular day, the Beneficial Owner of Book-Entry Notes must
so direct the applicable Participant before such Participant's cut-off time
for accepting instructions for that day. Different firms may have different
cut-off times for accepting instructions from their customers. Accordingly,
Beneficial Owners of Book-Entry Notes should consult the Participants through
which they own their interest in the Book-Entry Notes for the cut-off times
for such Participants. All notices shall be executed by a duly authorized
officer of such Participant (with signature guaranteed) and shall be
irrevocable. In addition, such Beneficial Owners of Book-Entry Notes shall
effect delivery of such Book-Entry Notes at the time such notices of election
are given to the Depository by causing the Participant to transfer such
Beneficial Owner's interest in the Book-Entry Notes, on the Depository's
records, to the Trustee. Conveyance of notices and other communications by the
Depository to Participants, by Participants to Indirect Participants (as
defined below) and by Participants and Indirect Participants to Beneficial
Owners of the Book-Entry Notes will be governed by agreements among them,
subject to any statutory or regulatory requirements as may be in effect from
time to time.
 
                                      S-6
<PAGE>
 
  The Company may at any time purchase Notes at any price or prices in the
open market or otherwise. Notes so purchased by the Company may, at the
discretion of the Company, be held, resold or surrendered to the Trustee for
cancellation.
 
INTEREST
 
"General"
 
  Each Note will bear interest from the date of issue at the rate per annum
or, in the case of a Floating Rate Note, pursuant to the interest rate formula
stated therein and in the applicable Pricing Supplement until the principal
thereof is paid or made available for payment. Interest will be payable in
arrears on each date specified in the applicable Pricing Supplement on which
an installment of interest is due and payable (an "Interest Payment Date") and
at Maturity. The first payment of interest on any Note originally issued
between a Regular Record Date and the related Interest Payment Date will be
made on the Interest Payment Date immediately following the next succeeding
Regular Record Date to the registered Holder on such next succeeding Regular
Record Date. The "Regular Record Date" shall be the fifteenth calendar day
(whether or not a Business Day) (as defined below) immediately preceding the
related Interest Payment Date.
 
 "Fixed Rate Notes"
 
  Unless otherwise specified in an applicable Pricing Supplement, each Fixed
Rate Note will bear interest from, and including, the date of issue, at the
rate per annum stated on the face thereof until the principal amount thereof
is paid or made available for payment. Interest payments on Fixed Rate Notes
will equal the amount of interest accrued from and including the immediately
preceding Interest Payment Date in respect of which interest has been paid (or
from and including the date of issue, if no interest has been paid with
respect to such Fixed Rate Notes), to, but excluding, the related Interest
Payment Date or Maturity, as the case may be. Unless otherwise specified in
the applicable Pricing Supplement, interest on Fixed Rate Notes will be
computed on the basis of a 360-day year of twelve 30-day months.
 
  Unless otherwise specified in the applicable Pricing Supplement, interest on
Fixed Rate Notes will be payable semiannually on May 15 and November 15 of
each year and at Maturity. If any Interest Payment Date or the Maturity of a
Fixed Rate Note falls on a day that is not a Business Day, the related payment
of principal, premium, if any, or interest will be made on the next succeeding
Business Day as if made on the date such payment was due, and no interest will
accrue on the amount so payable for the period from and after such Interest
Payment Date or Maturity, as the case may be.
 
 "Floating Rate Notes"
 
  Floating Rate Notes will be issued as described below. Each applicable
Pricing Supplement will specify certain terms with respect to which such
Floating Rate Note is being delivered, including: whether such Floating Rate
Note is a "Regular Floating Rate Note" (as defined below), an "Inverse
Floating Rate Note" (as defined below) or a "Floating Rate/Fixed Rate Note"
(as defined below); the Interest Rate Basis or Bases, Initial Interest Rate,
Interest Reset Dates, Interest Payment Dates, Index Maturity, Maximum Interest
Rate and Minimum Interest Rate, if any, and the Spread and/or Spread
Multiplier, if any, and, if one or more of the specified Interest Rate Bases
is LIBOR, the Index Currency, the Index Maturity and the Designated LIBOR Page
or, if one or more of the specified Interest Rate Bases is the CMT Rate, the
Designated CMT Telerate Page and Designated CMT Maturity Index, as described
below.
 
  The interest rate borne by the Floating Rate Notes will be determined as
follows:
 
    (i) Unless such Floating Rate Note is designated as a Floating Rate/Fixed
  Rate Note, an Inverse Floating Rate Note or as having an Addendum attached
  or as having "Other Provisions" apply relating to a different interest rate
  formula, such Floating Rate Note will be designated a "Regular Floating
  Rate Note" and, except as described below or in an applicable Pricing
  Supplement, bear interest at the rate determined
 
                                      S-7
<PAGE>
 
  by reference to the applicable Interest Rate Basis or Bases (i) plus or
  minus the applicable Spread, if any, and/or (ii) multiplied by the
  applicable Spread Multiplier, if any. Commencing on the first Interest
  Reset Date, the rate at which interest on such Regular Floating Rate Note
  shall be payable shall be reset as of each Interest Reset Date; provided,
  however, that the interest rate in effect for the period from the Original
  Issue Date to the first Interest Reset Date will be the Initial Interest
  Rate.
 
    (ii) If such Floating Rate Note is designated as a "Floating Rate/Fixed
  Rate Note", then such Floating Rate Note will bear interest at the rate
  determined by reference to the applicable Interest Rate Basis or Bases (i)
  plus or minus the applicable Spread, if any, and/or (ii) multiplied by the
  applicable Spread Multiplier, if any. Commencing on the first Interest
  Reset Date, the rate at which interest on such Floating Rate/Fixed Rate
  Note shall be payable shall be reset as of each Interest Reset Date;
  provided, however, that (i) the interest rate in effect for the period from
  the Original Issue Date to the first Interest Reset Date will be the
  Initial Interest Rate, and (ii) the interest rate in effect commencing on,
  and including, the Fixed Rate Commencement Date to Maturity shall be the
  Fixed Interest Rate, if such rate is specified in the applicable Pricing
  Supplement, or if no such Fixed Interest Rate is so specified, the interest
  rate in effect thereon on the day immediately preceding the Fixed Rate
  Commencement Date.
 
    (iii) If such Floating Rate Note is designated as an "Inverse Floating
  Rate Note," then, except as described below, such Floating Rate Note will
  bear interest equal to the Fixed Interest Rate specified in the related
  Pricing Supplement minus the rate determined by reference to the applicable
  Interest Rate Basis or Bases (i) plus or minus the applicable Spread, if
  any, and/or (ii) multiplied by the applicable Spread Multiplier, if any;
  provided, however, that unless otherwise specified in the applicable
  Pricing Supplement, the interest rate thereon will not be less than zero
  percent. Commencing on the first Interest Reset Date, the rate at which
  interest on such Inverse Floating Rate Note is payable shall be reset as of
  each Interest Reset Date; provided, however, that the interest rate in
  effect for the period from the Original Issue Date to the first Interest
  Reset Date will be the Initial Interest Rate.
 
  Notwithstanding the foregoing, if such Floating Rate Note is designated as
having an Addendum attached or as having "Other Provisions" apply as specified
on the face thereof, such Floating Rate Note shall bear interest in accordance
with the terms described in such Addendum or specified under "Other
Provisions" and the applicable Pricing Supplement.
 
  Each Interest Rate Basis shall be the rate determined in accordance with the
applicable provisions below. Except as set forth above, the interest rate in
effect on each day shall be (a) if such day is an Interest Reset Date, the
interest rate determined as of the Interest Determination Date (as defined
below) immediately preceding such Interest Reset Date or (b) if such day is
not an Interest Reset Date, the interest rate determined as of the Interest
Determination Date immediately preceding the applicable Interest Reset Date.
 
  Interest on Floating Rate Notes will be determined by reference to an
"Interest Rate Basis," which may be one or more of (i) the "CD Rate," (ii) the
"CMT Rate," (iii) the "Commercial Paper Rate," (iv) the "Eleventh District
Cost of Funds Rate," (v) the "Federal Funds Rate," (vi) "LIBOR," (vii) the
"Prime Rate," (viii) the "Treasury Rate," or (ix) such other Interest Rate
Basis or interest rate formula as may be set forth in the applicable Pricing
Supplement. In addition, a Floating Rate Note may bear interest in respect of
two or more Interest Rate Bases.
 
  The "Spread" is the number of basis points to be added to or subtracted from
the related Interest Rate Basis or Bases applicable to such Floating Rate
Note. The "Spread Multiplier" is the percentage of the related Interest Rate
Basis or Bases applicable to such Floating Rate Note by which such Interest
Rate Basis or Bases will be multiplied to determine the applicable interest
rate on such Floating Rate Note. The "Index Maturity" is the period to
maturity of the instrument or obligation with respect to which the Interest
Rate Basis or Bases will be calculated.
 
  Each applicable Pricing Supplement will specify the dates on which such
Interest Rate will be reset (each, an "Interest Reset Date"). Unless otherwise
specified in the applicable Pricing Supplement, the Interest Reset
 
                                      S-8
<PAGE>
 
Date will be, in the case of Floating Rate Notes which reset: (i) daily, each
Business Day; (ii) weekly, the Wednesday of each week (with the exception of
weekly reset Treasury Rate Notes which will reset the Tuesday of each week,
except as specified below); (iii) monthly, the third Wednesday of each month
(with the exception of monthly reset Eleventh District Cost of Funds Rate
Notes, which will reset on the first calendar day of the month); (iv)
quarterly, the third Wednesday of March, June, September and December of each
year; (v) semiannually, the third Wednesday of the two months specified in the
applicable Pricing Supplement; and (vi) annually, the third Wednesday of the
month specified in the applicable Pricing Supplement; provided, however, that
with respect to Floating Rate/Fixed Rate Notes, the fixed rate of interest in
effect for the period from the Fixed Rate Commencement Date until Maturity
shall be the Fixed Interest Rate or the interest rate in effect on the day
immediately preceding the Fixed Rate Commencement Date, as specified in the
applicable Pricing Supplement. If any Interest Reset Date for any Floating
Rate Note would otherwise be a day that is not a Business Day, such Interest
Reset Date will be postponed to the next succeeding day that is a Business
Day, except that in the case of a Floating Rate Note as to which LIBOR is an
applicable Interest Rate Basis, if such Business Day falls in the next
succeeding calendar month, such Interest Reset Date will be the immediately
preceding Business Day. In addition, in the case of a Floating Rate Note for
which the Treasury Rate is an applicable Interest Rate Basis and the Interest
Determination Date would otherwise fall on an Interest Reset Date, then such
Interest Reset Date will be postponed to the next succeeding Business Day. As
used herein, "Business Day" means any day, other than a Saturday or Sunday,
that is neither a legal holiday nor a day on which banking institutions are
authorized or required by law, regulation or executive order to close in The
City of New York; provided, however, that, with respect to non-United States-
dollar denominated Notes, such day is also not a day on which banking
institutions are authorized or required by law, regulation or executive order
to close in the Principal Financial Center (as hereinafter defined) of the
country issuing the Specified Currency (unless the Specified Currency is
European Currency Units ("ECU"), in which case such day is also not a day that
appears as an ECU non-settlement day on the displayed designated as "ISDE" on
the Reuter Monitor Money Rates Service (or is not a day designated as an ECU
non-settlement day by the ECU Banking Association) or, if ECU non-settlement
days do not appear on that page (and are not so designated), a day that is not
a day on which payments in ECU cannot be settled in the international
interbank market, as determined by the Calculation Agent); provided, further,
that, with respect to Notes as to which LIBOR is an applicable Interest Rate
Basis, such day is also a London Business Day. "London Business Day" means a
day on which dealings in the Index Currency (as hereinafter defined) are
transacted in the London interbank market.
 
  A Floating Rate Note may also have either or both of the following: (i) a
maximum numerical limitation, or ceiling, on the rate at which interest may
accrue during any interest period (a "Maximum Interest Rate"), and (ii) a
minimum numerical limitation, or floor, on the rate at which interest may
accrue during any period (a "Minimum Interest Rate"). The Indenture provides
that the Indenture and the Securities will be governed by and construed in
accordance with the laws of the State of New York. Under present New York law,
the maximum rate of interest is 25% per annum on a simple interest basis. This
limit may not apply to Securities in which $2,500,000 or more has been
invested. While the Company believes that New York law would be given effect
by a state or federal court sitting outside of New York, state laws frequently
regulate the amount of interest that may be charged to and paid by a borrower
(including, in some cases, corporate borrowers). It is suggested that
prospective investors consult their personal advisors with respect to the
applicability of such laws. The Company has covenanted for the benefit of the
beneficial owners of the Securities, to the extent permitted by law, not to
claim voluntarily the benefits of any laws concerning usurious rates of
interest against a beneficial owner of the Securities.
 
  Each applicable Pricing Supplement will specify the dates on which interest
will be payable (each an "Interest Payment Date"). Each Floating Rate Note
will bear interest from the date of issue at the rates specified therein until
the principal thereof is paid or otherwise made available for payment. Unless
otherwise specified in the applicable Pricing Supplement and, except as
provided below, interest will be payable in the case of Floating Rate Notes
which reset: (i) daily, weekly or monthly, on the third Wednesday of each
month or on the third Wednesday of March, June, September and December of each
year as specified in the applicable Pricing Supplement; (ii) quarterly, on the
third Wednesday of March, June, September and December of each year; (iii)
 
                                      S-9
<PAGE>
 
semiannually, on the third Wednesday of the two months of each year specified
in the applicable Pricing Supplement; and (iv) annually, on the third
Wednesday of the month of each year specified in the applicable Pricing
Supplement and, in each case, at Maturity. If any Interest Payment Date for
any Floating Rate Note (other than an Interest Payment Date at Maturity) would
otherwise be a day that is not a Business Day, such Interest Payment Date will
be postponed to the next succeeding day that is a Business Day except that in
the case of a Floating Rate Note as to which LIBOR is an applicable Interest
Rate Basis, if such Business Day falls in the next succeeding calendar month,
such Interest Payment Date will be the immediately preceding Business Day. If
the Maturity of a Floating Rate Note falls on a day that is not a Business
Day, the payment of principal, premium, if any, and interest will be made on
the next succeeding Business Day, and no interest on such payment will accrue
for the period from and after such Maturity.
 
  All percentages resulting from any calculation on Floating Rate Notes will
be rounded to the nearest one hundred-thousandth of a percentage point, with
five one millionths of a percentage point rounded upwards (e.g., 9.876545% (or
 .09876545) would be rounded to 9.87655% (or .0987655)), and all dollar amounts
used in or resulting from such calculation on Floating Rate Notes will be
rounded to the nearest cent (with one-half cent being rounded upward).
 
  Interest payments on Floating Rate Notes will equal the amount of interest
accrued from and including the immediately preceding Interest Payment Date in
respect of which interest has been paid (or from and including the date of
issue, if no interest has been paid with respect to such Floating Rate Notes),
to but excluding the related Interest Payment Date or Maturity.
 
  With respect to each Floating Rate Note, accrued interest is calculated by
multiplying its face amount by an accrued interest factor. Such accrued
interest factor is computed by adding the interest factor calculated for each
day in the period for which accrued interest is being calculated. The interest
factor for each such day will be computed by dividing the interest rate
applicable to such day by 360, in the case of Notes for which the Interest
Rate Basis is the CD Rate, the Commercial Paper Rate, the Eleventh District
Cost of Funds Rate, the Federal Funds Rate, LIBOR or the Prime Rate, or by the
actual number of days in the year in the case of Notes for which the Interest
Rate Basis is the CMT Rate or the Treasury Rate. The interest factor for Notes
for which the interest rate is calculated with reference to two or more
Interest Rate Bases will be calculated in each period in the same manner as if
only one of the applicable Interest Rate Bases applied.
 
  The interest rate applicable to each interest reset period commencing on the
Interest Reset Date with respect to such interest reset period will be the
rate determined as of the applicable "Interest Determination Date." The
Interest Determination Date with respect to the CD Rate, the CMT Rate and the
Commercial Paper Rate will be the second Business Day preceding each Interest
Reset Date for the related Note; the Interest Determination Date with respect
to the Federal Funds Rate and the Prime Rate, unless otherwise specified in
the applicable Pricing Supplement, will be the Business Day immediately
preceding each Interest Reset Date; the Interest Determination Date with
respect to the Eleventh District Cost of Funds Rate will be the last working
day of the month immediately preceding each Interest Reset Date on which the
Federal Home Loan Bank of San Francisco (the "FHLB of San Francisco")
publishes the Index (as defined below); the Interest Determination Date with
respect to LIBOR will be the second London Business Day preceding each
Interest Reset Date. With respect to the Treasury Rate, unless otherwise
specified in an applicable Pricing Supplement, the Interest Determination Date
will be the day in the week in which the related Interest Reset Date falls on
which day Treasury Bills (as defined below) are normally auctioned (Treasury
Bills are normally sold at auction on Monday of each week, unless that day is
a legal holiday, in which case the auction is normally held on the following
Tuesday, except that such auction may be held on the preceding Friday);
provided, however, that if an auction is held on the Friday of the week
preceding the related Interest Reset Date, the related Interest Determination
Date will be such preceding Friday; and provided, further, that if an auction
falls on any Interest Reset Date, then the related Interest Reset Date will
instead be the first Business Day following such auction. Unless otherwise
specified in the applicable Pricing Supplement, the Interest Determination
Date pertaining to a Floating Rate Note the interest rate of which is
determined with reference to two or more Interest Rate Bases will be the
latest Business Day which is at least two Business Days prior to such Interest
Reset Date for such Floating Rate Note on which each Interest Reset Basis is
determinable. Each Interest Rate Basis will be determined on such date, and
the applicable interest rate will take effect on the related Interest Reset
Date.

  Unless otherwise provided in the applicable Pricing Supplement, Merrill
Lynch, Pierce, Fenner & Smith Incorporated, a subsidiary of the Company, will
be the "Calculation Agent." Upon the request of the Holder of any Floating
Rate Note, the Calculation Agent will provide the interest rate then in effect
and, if determined, the interest rate that will become effective as a result
of a determination made for the next Interest Reset Date with respect to such
Floating Rate Note. Unless otherwise specified in the applicable Pricing
Supplement, the "Calculation Date," if applicable, pertaining to any Interest
Determination Date will be the earlier of (i) the tenth calendar day after
such Interest Determination Date, or, if such day is not a Business Day, the
next succeeding Business Day or (ii) the Business Day preceding the applicable
Interest Payment Date or Maturity, as the case may be.
 
  "CD Rate." CD Rate Notes will bear interest at the rates (calculated with
reference to the CD Rate and the Spread and/or Spread Multiplier, if any)
specified in such CD Rate Notes and in any applicable Pricing Supplement.
 
  "CD Rate" means, with respect to any Interest Determination Date relating to
a CD Rate Note or any Floating Rate Note for which the interest rate is
determined with reference to the CD Rate (a "CD Rate Interest Determination
Date"), the rate on such date for negotiable United States dollar certificates
of deposit having the Index Maturity specified in the applicable Pricing
Supplement as published by the Board of Governors of the Federal Reserve
System in "Statistical Release H.15(519), Selected Interest Rates" or any
successor publication ("H.15(519)") under the heading "CDs (Secondary
Market)," or, if not published by 3:00 P.M., New York City time, on the
related Calculation Date, the rate on such CD Rate Interest Determination Date
for negotiable United States dollar certificates of deposit of the Index
Maturity specified in the applicable Pricing Supplement as published by the
Federal Reserve Bank of New York in its daily statistical release "Composite
3:30 P.M. Quotations for U.S. Government Securities" or any successor
publication ("Composite Quotations") under the heading "Certificates of
Deposit." If such rate is not yet published in either H.15(519) or Composite
Quotations by 3:00 P.M., New York City time, on the related Calculation Date,
then the CD Rate on such CD Rate Interest Determination Date will be
calculated by the Calculation Agent and will be the arithmetic mean of the
secondary market offered rates as of 10:00 A.M., New York City time, on such
CD Rate Interest Determination Date, of three leading non-bank dealers in
negotiable United States dollar certificates of deposit in The City of New
York selected by the Calculation Agent for negotiable United States dollar
certificates of deposit of major United States money market banks with a
remaining maturity closest to the Index Maturity designated in the applicable
Pricing Supplement in an amount that is representative for a single
transaction in that market at that time; provided, however, that if the
dealers so selected by the Calculation Agent are not quoting as set forth
above, the CD Rate with respect to such CD Rate Interest Determination Date
will be the CD Rate in effect on such CD Rate Interest Determination Date.
 
  "CMT Rate." CMT Rate Notes will bear interest at the rates (calculated with
reference to the CMT Rate and the Spread and/or Spread Multiplier, if any)
specified in such CMT Rate Notes and in any applicable Pricing Supplement.
 
  "CMT Rate" means, with respect to any Interest Determination Date relating
to any Floating Rate Note for which the interest rate is determined with
reference to the CMT Rate (a "CMT Rate Interest Determination Date"), the rate
displayed on the Designated CMT Telerate Page under the caption "Treasury
Constant Maturities. Federal Reserve Board Release H.15. Mondays Approximately
3:45 P.M.," under the column for the Designated CMT Maturity Index for (i) if
the Designated CMT Telerate Page is 7055, the rate on such CMT Rate Interest
Determination Date and (ii) if the Designated CMT Telerate Page is 7052, the
weekly or the monthly average, as specified in the Pricing Supplement, for the
week or the month, as applicable, ended immediately preceding the week in
which the related CMT Rate Interest Determination Date occurs. If such rate is
no longer displayed on the relevant page or is not displayed by 3:00 P.M., New
York City time, on the related Calculation Date, then the CMT Rate for such
CMT Rate Interest Determination Date will be such treasury constant maturity
rate for the Designated CMT Maturity Index as published in the relevant
H.15(519). If such rate is no longer published or is not published by 3:00
P.M., New York City time, on the related Calculation
 
                                     S-11
<PAGE>
 
Date, then the CMT Rate on such CMT Rate Interest Determination Date will be
such treasury constant maturity rate of the Designated CMT Maturity Index (or
other United States Treasury rate for the Designated CMT Maturity Index) for
the CMT Rate Interest Determination Date with respect to such Interest Reset
Date as may then be published by either the Board of Governors of the Federal
Reserve System or the United States Department of the Treasury that the
Calculation Agent determines to be comparable to the rate formerly displayed
on the Designated CMT Telerate Page and published in the relevant H.15(519).
If such information is not provided by 3:00 P.M., New York City time, on the
related Calculation Date, then the CMT Rate on the CMT Rate Interest
Determination Date will be calculated by the Calculation Agent and will be a
yield to maturity, based on the arithmetic mean of the secondary market
closing offer side prices as of approximately 3:30 P.M., New York City time,
on such CMT Rate Interest Determination Date reported, according to their
written records, by three leading primary United States government securities
dealers (each, a "Reference Dealer") in The City of New York (which may
include the Agent or its affiliates) selected by the Calculation Agent (from
five such Reference Dealers selected by the Calculation Agent and eliminating
the highest quotation (or, in the event of equality, one of the highest) and
the lowest quotation (or, in the event of equality, one of the lowest)), for
the most recently issued direct noncallable fixed rate obligations of the
United States ("Treasury Notes") with an original maturity of approximately
the Designated CMT Maturity Index and a remaining term to maturity of not less
than such Designated CMT Maturity Index minus one year. If the Calculation
Agent is unable to obtain three such Treasury Note quotations, the CMT Rate on
such CMT Rate Interest Determination Date will be calculated by the
Calculation Agent and will be a yield to maturity based on the arithmetic mean
of the secondary market offer side prices as of approximately 3:30 P.M., New
York City time, on such CMT Rate Interest Determination Date of three
Reference Dealers in The City of New York (from five such Reference Dealers
selected by the Calculation Agent and eliminating the highest quotation (or,
in the event of equality, one of the highest) and the lowest quotation (or, in
the event of equality, one of the lowest)), for Treasury Notes with an
original maturity of the number of years that is the next highest to the
Designated CMT Maturity Index and a remaining term to maturity closest to the
Designated CMT Maturity Index and in an amount of at least $100 million. If
three or four (and not five) of such Reference Dealers are quoting as
described above, then the CMT Rate will be based on the arithmetic mean of the
offer prices obtained and neither the highest nor the lowest of such quotes
will be eliminated; provided, however, that if fewer than three Reference
Dealers so selected by the Calculation Agent are quoting as mentioned herein,
the CMT Rate determined as of such CMT Rate Interest Determination Date will
be the CMT Rate in effect on such CMT Rate Interest Determination Date. If two
Treasury Notes with an original maturity as described in the second preceding
sentence have remaining terms to maturity equally close to the Designated CMT
Maturity Index, the Calculation Agent will obtain from five Reference Dealers
quotations for the Treasury Note with the shorter remaining term to maturity.
 
  "Designated CMT Telerate Page" means the display on the Dow Jones Telerate
Service on the page specified in the applicable Pricing Supplement (or any
other page as may replace such page on that service for the purpose of
displaying Treasury Constant Maturities as reported in H.15(519)) for the
purpose of displaying Treasury Constant Maturities as reported in H.15(519).
If no such page is specified in the applicable Pricing Supplement, the
Designated CMT Telerate Page shall be 7052 for the most recent week.
 
  "Designated CMT Maturity Index" means the original period to maturity of the
U.S. Treasury securities (either 1, 2, 3, 5, 7, 10, 20 or 30 years) specified
in the applicable Pricing Supplement with respect to which the CMT Rate will
be calculated. If no such maturity is specified in the applicable Pricing
Supplement, the Designated CMT Maturity Index shall be 2 years.
 
  "Commercial Paper Rate." Commercial Paper Rate Notes will bear interest at the
rates (calculated with reference to the Commercial Paper Rate and the Spread
and/or Spread Multiplier, if any) specified in such Commercial Paper Rate
Notes and in any applicable Pricing Supplement.
 
  "Commercial Paper Rate" means, with respect to any Interest Determination
Date relating to a Commercial Paper Rate Note or any Floating Rate Note for
which the interest rate is determined with reference to the Commercial Paper
Rate (a "Commercial Paper Rate Interest Determination Date"), the Money Market
Yield
 
                                     S-12
<PAGE>
 
(as defined below) on such date of the rate for commercial paper having the
Index Maturity specified in the applicable Pricing Supplement as published in
H.15(519) under the heading "Commercial Paper." In the event that such rate is
not published by 3:00 P.M., New York City time, on the related Calculation
Date, then the Commercial Paper Rate will be the Money Market Yield on such
Commercial Paper Rate Interest Determination Date of the rate for commercial
paper having the Index Maturity specified in the applicable Pricing Supplement
as published in Composite Quotations under the heading "Commercial Paper"
(with an Index Maturity of one month or three months being deemed to be
equivalent to an Index Maturity of 30 days or 90 days, respectively). If by
3:00 P.M., New York City time, on the related Calculation Date such rate is
not yet published in either H.15(519) or Composite Quotations, then the
Commercial Paper Rate for such Commercial Paper Rate Interest Determination
Date will be calculated by the Calculation Agent and will be the Money Market
Yield of the arithmetic mean of the offered rates at approximately 11:00 A.M.,
New York City time, on such Commercial Paper Rate Interest Determination Date
of three leading dealers of commercial paper in The City of New York selected
by the Calculation Agent for commercial paper having the Index Maturity
designated in the applicable Pricing Supplement placed for an industrial
issuer whose bond rating is "Aa", or the equivalent, from a nationally
recognized securities rating agency; provided, however, that if the dealers so
selected by the Calculation Agent are not quoting as mentioned in this
sentence, the Commercial Paper Rate determined on such Commercial Paper Rate
Interest Determination Date will be the rate in effect on such Commercial
Paper Rate Interest Determination Date.
 
  "Money Market Yield" means a yield (expressed as a percentage) calculated in
accordance with the following formula:
 
                                         D X 360
                  Money Market Yield = _______________  X 100
                                        360 - (D X M)
 
where "D" refers to the applicable per annum rate for commercial paper quoted
on a bank discount basis and expressed as a decimal, and "M" refers to the
actual number of days in the interest period for which interest is being
calculated.
 
  "Eleventh District Cost of Funds Rate." Eleventh District Cost of Funds Rate
Notes will bear interest at the rates (calculated with reference to the
Eleventh District Cost of Funds Rate and the Spread and/or Spread Multiplier,
if any) specified in such Eleventh District Cost of Funds Rate Notes and in
any applicable Pricing Supplement.
 
  "Eleventh District Cost of Funds Rate" means, with respect to any Interest
Determination Date relating to an Eleventh District Cost of Funds Rate Note or
any Floating Rate Note for which the interest rate is determined with
reference to the Eleventh District Cost of Funds Rate (an "Eleventh District
Cost of Funds Rate Interest Determination Date"), the rate equal to the
monthly weighted average cost of funds for the calendar month preceding such
Eleventh District Cost of Funds Rate Interest Determination Date as set forth
under the caption "11th District" on Telerate Page 7058 as of 11:00 A.M., San
Francisco time, on such Eleventh District Cost of Funds Rate Interest
Determination Date. If such rate does not appear on Telerate Page 7058 on any
related Eleventh District Cost of Funds Rate Interest Determination Date, the
Eleventh District Cost of Funds for such Eleventh District Cost of Funds Rate
Interest Determination Date shall be the monthly weighted average cost of
funds paid by member institutions of the Eleventh Federal Home Loan Bank
District that was most recently announced (the "Index") by the FHLB of San
Francisco as such cost of funds for the calendar month preceding the date of
such announcement. If the FHLB of San Francisco fails to announce the Index on
or prior to such Eleventh District Cost of Funds Rate Interest Determination
Date for the calendar month immediately preceding such Eleventh District Cost
of Funds Rate Interest Determination Date, then the Eleventh District Cost of
Funds Rate for such Eleventh District Cost of Funds Rate Interest
Determination Date will be the Eleventh District Cost of Funds Rate in effect
on such Eleventh District Cost of Funds Rate Interest Determination Date.
 
  "Federal Funds Rate." Federal Funds Rate Notes will bear interest at the rates
(calculated with reference to the Federal Funds Rate and the Spread and/or
Spread Multiplier, if any) specified in such Federal Funds Rate Notes and in
any applicable Pricing Supplement.
 
                                     S-13
<PAGE>
 
  "Federal Funds Rate" means, with respect to any Interest Determination Date
relating to a Federal Funds Rate Note or any Floating Rate Note for which the
interest rate is determined with reference to the Federal Funds Rate (a
"Federal Funds Rate Interest Determination Date"), the rate on such date for
United States dollar Federal Funds as published in H.15(519) under the heading
"Federal Funds (Effective)" or, if not published by 3:00 P.M., New York City
time, on the related Calculation Date, the rate on such Federal Funds Rate
Interest Determination Date as published in Composite Quotations under the
heading "Federal Funds/Effective Rate." If such rate is not published in
either H.15(519) or Composite Quotations by 3:00 P.M., New York City time, on
the related Calculation Date, the Federal Funds Rate for such Federal Funds
Rate Interest Determination Date will be calculated by the Calculation Agent
and will be the arithmetic mean of the rates for the last transaction in
overnight United States dollar federal funds arranged by three leading brokers
of federal funds transactions in The City of New York selected by the
Calculation Agent prior to 9:00 A.M., New York City time on such Federal Funds
Rate Interest Determination Date; provided, however, that if the brokers so
selected by the Calculation Agent are not quoting as mentioned in this
sentence, the Federal Funds Rate with respect to such Federal Funds Rate
Interest Determination Date will be the Federal Funds Rate in effect on such
Federal Funds Rate Interest Determination Date.
 
  "LIBOR." LIBOR Notes will bear interest at the rates (calculated with
reference to LIBOR and the Spread and/or Spread Multiplier, if any) specified
in such LIBOR Notes and in any applicable Pricing Supplement.
 
  "LIBOR" means the rate determined by the Calculation Agent in accordance
with the following provisions:
 
    (i) With respect to an Interest Determination Date relating to a LIBOR
  Note or any Floating Rate Note for which the interest rate is determined
  with reference to LIBOR (a "LIBOR Interest Determination Date"), LIBOR will
  be either: (a) if "LIBOR Reuters" is specified in the applicable Pricing
  Supplement, the arithmetic mean of the offered rates (unless the specified
  Designated LIBOR Page (as defined below) by its terms provides only for a
  single rate, in which case such single rate shall be used) for deposits in
  the Index Currency (as defined below) having the Index Maturity designated
  in the applicable Pricing Supplement, commencing on the second London
  Business Day immediately following that LIBOR Interest Determination Date,
  that appear on the Designated LIBOR Page specified in the applicable
  Pricing Supplement as of 11:00 A.M., London time, on that LIBOR Interest
  Determination Date, if at least two such offered rates appear (unless, as
  aforesaid, only a single rate is required) on such Designated LIBOR Page,
  or (b) if "LIBOR Telerate" is specified in the applicable Pricing
  Supplement, the rate for deposits in the Index Currency having the Index
  Maturity designated in the applicable Pricing Supplement commencing on the
  second London Business Day immediately following that LIBOR Interest
  Determination Date that appears on the Designated LIBOR Page specified in
  the applicable Pricing Supplement as of 11:00 A.M., London time, on that
  LIBOR Interest Determination Date. If fewer than two offered rates appear,
  or no rate appears, as applicable, LIBOR in respect of the related LIBOR
  Interest Determination Date will be determined as if the parties had
  specified the rate described in clause (ii) below.
 
    (ii) With respect to a LIBOR Interest Determination Date on which fewer
  than two offered rates appear, or no rate appears, as the case may be, on
  the applicable Designated LIBOR Page as specified in clause (i) above, the
  Calculation Agent will request the principal London offices of each of four
  major reference banks in the London interbank market, as selected by the
  Calculation Agent, to provide the Calculation Agent with its offered
  quotation for deposits in the Index Currency for the period of the Index
  Maturity designated in the applicable Pricing Supplement, commencing on the
  second London Business Day immediately following such LIBOR Interest
  Determination Date, to prime banks in the London interbank market at
  approximately 11:00 A.M., London time, on such LIBOR Interest Determination
  Date and in a principal amount that is representative for a single
  transaction in such Index Currency in such market at such time. If at least
  two such quotations are provided, LIBOR determined on such LIBOR Interest
  Determination Date will be the arithmetic mean of such quotations. If fewer
  than two quotations are provided, LIBOR determined on such LIBOR Interest
  Determination Date will be the arithmetic mean of the rates quoted at
  approximately 11:00 A.M. (or such other time specified in the applicable
  Pricing Supplement), in the applicable Principal Financial Center(s) (as
  defined below), on such LIBOR Interest
 
                                     S-14
<PAGE>
 
  Determination Date by three major banks in such Principal Financial Center
  selected by the Calculation Agent for loans in the Index Currency to
  leading European banks, having the Index Maturity designated in the
  applicable Pricing Supplement and in a principal amount that is
  representative for a single transaction in such Index Currency in such
  market at such time; provided, however, that if the banks so selected by
  the Calculation Agent are not quoting as mentioned in this sentence, LIBOR
  determined on such LIBOR Interest Determination Date will be LIBOR in
  effect on such LIBOR Interest Determination Date.
 
  "Index Currency" means the currency (including composite currencies)
specified in the applicable Pricing Supplement as the currency for which LIBOR
shall be calculated. If no such currency is specified in the applicable
Pricing Supplement, the Index Currency shall be United States dollars.
 
  "Designated LIBOR Page" means either (a) if "LIBOR Reuters" is designated in
the applicable Pricing Supplement, the display on the Reuter Monitor Money
Rates Service for the purpose of displaying the London interbank rates of
major banks for the applicable Index Currency, or (b) if "LIBOR Telerate" is
designated in the applicable Pricing Supplement, the display on the Dow Jones
Telerate Service (or such other service or services as may be nominated by the
British Bankers' Association for the purpose of displaying London interbank
offered rates for the Index Currency) for the purpose of displaying the London
interbank rates of major banks for the applicable Index Currency. If neither
LIBOR Reuters nor LIBOR Telerate is specified in the applicable Pricing
Supplement, LIBOR for the applicable Index Currency will be determined as if
LIBOR Telerate (and, if the United States dollar is the Index Currency, Page
3750) had been specified.
 
  "Principal Financial Center" means, unless otherwise specified in the
applicable Pricing Supplement, (i) the capital city of the country issuing the
Specified Currency (except with respect to ECU) or (ii) the capital city of
the country to which the Index Currency, if applicable, relates (or, in the
case of ECU, Luxembourg), except, in each case, that with respect to United
States dollars, Australian dollars, Canadian dollars, Deutsche marks, Dutch
guilders, Italian lire and Swiss francs, the "Principal Financial Center"
shall be The City of New York, Sydney, Toronto, Frankfurt, Amsterdam, Milan
(solely in the case of clause (i) above) and Zurich, respectively.
 
  "Prime Rate." Prime Rate Notes will bear interest at the rates (calculated
with reference to the Prime Rate and the Spread and/or Spread Multiplier, if
any) specified in such Prime Rate Notes and any applicable Pricing Supplement.
 
  "Prime Rate" means the rate determined by the Calculation Agent in
accordance with the provisions set out in clause (i) or in clause (ii) below,
depending upon whether such rate is specified as "Prime Rate--Major Banks" or
as "Prime Rate--H.15" in the applicable Pricing Supplement:
 
    (i) If the applicable Pricing Supplement indicates that the applicable
  rate is "Prime Rate--Major Banks": "Prime Rate" means, with respect to any
  Interest Determination Date relating to a Prime Rate Note or any Floating
  Rate Note for which the interest rate is determined with reference to the
  Prime Rate (a "Prime Rate Interest Determination Date"), the arithmetic
  mean of the prime rates of interest publicly announced by three major banks
  in The City of New York as its United States dollar prime rate or base
  lending rate as in effect for that day. Each change in the prime rate or
  base lending rate of any bank so announced by such bank will be effective
  as of the effective date of the announcement or, if no effective date is
  specified, as of the date of the announcement. If fewer than three such
  quotations are provided, the Prime Rate will be calculated by the
  Calculation Agent and will be determined as the arithmetic mean on the
  basis of the prime rates quoted in The City of New York by three substitute
  banks or trust companies organized and doing business under the laws of the
  United States, or any state thereof, each having total equity capital of at
  least $500 million and being subject to supervision or examination by a
  federal or state
 
                                     S-15
<PAGE>
 
  authority, selected by the Calculation Agent to quote such rate or rates;
  provided, however, that if the banks or trust companies so selected by the
  Calculation Agent are not quoting as mentioned in this sentence, the Prime
  Rate with respect to such Prime Rate Interest Determination Date will be
  the Prime Rate in effect on such Prime Rate Interest Determination Date.
 
    (ii) If the applicable Pricing Supplement indicates that the applicable
  rate is "Prime Rate--H.15": "Prime Rate" means, with respect to any Prime
  Rate Interest Determination Date, the rate on such date as such rate is
  published in H.15(519) under the heading "Bank Prime Loan." If such rate is
  not published prior to 3:00 P.M., New York City time, on the related
  Calculation Date, then the Prime Rate shall be the arithmetic mean of the
  rates of interest publicly announced by each bank that appears on the
  Reuters Screen USPRIME1 as such bank's prime rate or base lending rate as
  in effect for that Prime Rate Interest Determination Date. If fewer than
  four such rates but more than one such rate appear on the Reuters Screen
  USPRIME1 for such Prime Rate Interest Determination Date, the Prime Rate
  shall be the arithmetic mean of the prime rates quoted on the basis of the
  actual number of days in the year divided by a 360-day year as of the close
  of business on such Prime Rate Interest Determination Date by four major
  money center banks in The City of New York selected by the Calculation
  Agent. If fewer than two such rates appear on the Reuters Screen USPRIME1,
  the Prime Rate will be determined by the Calculation Agent on the basis of
  the rates furnished in The City of New York by three substitute banks or
  trust companies organized and doing business under the laws of the United
  States, or any state thereof, having total equity capital of at least $500
  million and being subject to supervision or examination by Federal or state
  authority, selected by the Calculation Agent to provide such rate or rates;
  provided, however, that if the banks or trust companies selected as
  aforesaid are not quoting as mentioned in this sentence, the Prime Rate for
  such Prime Rate Interest Determination Date will be the Prime Rate in
  effect on such Prime Rate Interest Determination Date.
 
  "Reuters Screen USPRIME1" means the display designated as page "USPRIME1"
(or such other page as may replace such page) on that service for the purpose
of displaying prime rates or base lending rates of major United States banks.
 
  "Treasury Rate." Treasury Rate Notes will bear interest at the rates
(calculated with reference to the Treasury Rate and the Spread and/or Spread
Multiplier, if any) specified in such Treasury Rate Notes and in any
applicable Pricing Supplement.
 
  "Treasury Rate" means, with respect to an Interest Determination Date
relating to a Treasury Rate Note or any Floating Rate Note for which the
interest rate is determined by reference to the Treasury Rate (a "Treasury
Rate Interest Determination Date"), the rate applicable to the most recent
auction of direct obligations of the United States ("Treasury Bills") having
the Index Maturity specified in the applicable Pricing Supplement, as such
rate is published in H.15(519) under the heading "Treasury Bills-auction
average (investment)" or, if not published by 3:00 P.M., New York City time,
on the related Calculation Date, the auction average rate (expressed as a bond
equivalent on the basis of a year of 365 or 366 days, as applicable, and
applied on a daily basis) as otherwise announced by the United States
Department of the Treasury. In the event that the results of the auction of
Treasury Bills having the Index Maturity designated in the applicable Pricing
Supplement are not reported as provided by 3:00 P.M., New York City time, on
such Calculation Date, or if no such auction is held in a particular week,
then the Treasury Rate will be calculated by the Calculation Agent and will be
a yield to maturity (expressed as a bond equivalent on the basis of a year of
365 or 366 days, as applicable, and applied on a daily basis) of the
arithmetic mean of the secondary market bid rates, as of approximately 3:30
P.M., New York City time, on such Treasury Rate Interest Determination Date,
of three leading primary United States government securities dealers (which
may include the Agent) selected by the Calculation Agent, for the issue of
Treasury Bills with a remaining maturity closest to the Index Maturity
designated in the applicable Pricing Supplement; provided, however, that if
the dealers so selected by the Calculation Agent are not quoting as mentioned
in this sentence, the Treasury Rate with respect to such Treasury Rate
Interest Determination Date will be the Treasury Rate in effect on such
Treasury Rate Interest Determination Date.

OTHER PROVISIONS; ADDENDA
 
  Any provisions with respect to an issue of Notes, including the
determination of one or more Interest Rate Bases, the specification of one or
more Interest Rate Bases, calculation of the interest rate applicable to a
Floating Rate Note, its Interest Payment Dates or any other matter relating
thereto may be modified by the terms as specified under "Other Provisions" on
the face thereof or in an Addendum relating thereto, if so specified on the
face thereof and in the applicable Pricing Supplement.
 
ORIGINAL ISSUE DISCOUNT NOTES
 
  Notes may be issued at a price less than their redemption price at Maturity,
resulting in such Notes being treated as if they were issued with original
issue discount for federal income tax purposes ("Original Issue Discount
Notes"). Such Original Issue Discount Notes may currently pay no interest or
interest at a rate which at the time of issuance is below market rates.
Certain additional considerations relating to any Original Issue Discount
Notes may be described in the Pricing Supplement relating thereto.
 
AMORTIZING NOTES
 
  The Company may from time to time offer Amortizing Notes. Unless otherwise
specified in the applicable Pricing Supplement, interest on each Amortizing
Note will be computed on the basis of a 360-day year of twelve 30-day months.
Payments with respect to Amortizing Notes will be applied first to interest
due and payable thereon and then to the reduction of the unpaid principal
amount thereof. Further information concerning additional terms and conditions
of any issue of Amortizing Notes will be provided in the applicable Pricing
Supplement. A table setting forth repayment information in respect of each
Amortizing Note will be included in the applicable Pricing Supplement and set
forth on such Notes.
 
BOOK-ENTRY NOTES
 
  Upon issuance, all Book-Entry Notes having the same Original Issue Date,
Maturity and otherwise having identical terms and provisions will be
represented by one or more fully registered global Notes (the "Global Notes").
Each such Global Note will be deposited with, or on behalf of, The Depository
Trust Company as Depository (the "Depository") registered in the name of the
Depository or a nominee thereof. Unless and until it is exchanged in whole or
in part for Notes in definitive form, no Global Note may be transferred except
as a whole by the Depository to a nominee of such Depository or by a nominee
of such Depository to such Depository or another nominee of such Depository or
by such Depository or any such nominee to a successor of such Depository or a
nominee of such successor.
 
  The following is based on information furnished by the Depository:
 
  The Depository will act as securities depository for the Book-Entry Notes.
The Book-Entry Notes will be issued as fully registered securities registered
in the name of Cede & Co. (the Depository's partnership nominee). One fully
registered Global Note will be issued for each issue of Book-Entry Notes, each
in the aggregate principal amount of such issue, and will be deposited with
the Depository. If, however, the aggregate principal amount of any issue
exceeds $200,000,000, one Global Note will be issued with respect to each
$200,000,000 of principal amount and an additional Global Note will be issued
with respect to any remaining principal amount of such issue.
 
  The Depository is a limited-purpose trust company organized under the New
York Banking Law, a "banking organization" within the meaning of the New York
Banking Law, a member of the Federal Reserve System, a "clearing corporation"
within the meaning of the New York Uniform Commercial Code, and a "clearing
agency" registered pursuant to the provisions of Section 17A of the Exchange
Act. The Depository holds securities that its participants ("Participants")
deposit with the Depository. The Depository also facilitates the settlement
among Participants of securities transactions, such as transfers and pledges,
in deposited securities through electronic computerized book-entry changes in
Participants' accounts, thereby eliminating the need for
 
                                     S-17
<PAGE>
 
physical movement of securities certificates. Direct Participants of the
Depository ("Direct Participants") include securities brokers and dealers
(including the Agent), banks, trust companies, clearing corporations and
certain other organizations. The Depository is owned by a number of its Direct
Participants and by the New York Stock Exchange, Inc., the American Stock
Exchange, Inc., and the National Association of Securities Dealers, Inc.
Access to the Depository's system is also available to others such as
securities brokers and dealers, banks and trust companies that clear through
or maintain a custodial relationship with a Direct Participant, either
directly or indirectly ("Indirect Participants"). The rules applicable to the
Depository and its Participants are on file with the Securities and Exchange
Commission.
 
  Purchasers of Book-Entry Notes under the Depository's system must be made by
or through Direct Participants, which will receive a credit for such Book-
Entry Notes on the Depository's records. The ownership interest of each actual
purchaser of each Book-Entry Note represented by a Global Note ("Beneficial
Owner") is, in turn, to be recorded on the records of Direct Participants and
Indirect Participants. Beneficial Owners will not receive written confirmation
from the Depository of their purchase, but Beneficial Owners are expected to
receive written confirmations providing details of the transaction, as well as
periodic statements of their holdings, from the Direct Participants or
Indirect Participants through which such Beneficial Owner entered into the
transaction. Transfers of ownership interests in a Global Note representing
Book-Entry Notes are to be accomplished by entries made on the books of
Participants acting on behalf of Beneficial Owners. Beneficial Owners of a
Global Note representing Book-Entry Notes will not receive Certificated Notes
representing their ownership interests therein, except in the event that use
of the book-entry system for such Book-Entry Notes is discontinued.
 
  To facilitate subsequent transfers, all Global Notes representing Book-Entry
Notes which are deposited with, or on behalf of, the Depository are registered
in the name of the Depository's nominee, Cede & Co. The deposit of Global
Notes with, or on behalf of, the Depository and their registration in the name
of Cede & Co. effect no change in beneficial ownership. The Depository has no
knowledge of the actual Beneficial Owners of the Global Notes representing the
Book-Entry Notes; the Depository's records reflect only the identity of the
Direct Participants to whose accounts such Book-Entry Notes are credited,
which may or may not be the Beneficial Owners. The Participants will remain
responsible for keeping account of their holdings on behalf of their
customers.
 
  Conveyance of notices and other communications by the Depository to Direct
Participants, by Direct Participants to Indirect Participants, and by Direct
Participants and Indirect Participants to Beneficial Owners, will be governed
by arrangements among them, subject to any statutory or regulatory
requirements as may be in effect from time to time.
 
  Neither the Depository nor Cede & Co. will consent or vote with respect to
the Global Notes representing the Book-Entry Notes. Under its usual
procedures, the Depository mails an Omnibus Proxy to the Company as soon as
possible after the applicable record date. The Omnibus Proxy assigns Cede &
Co.'s consenting or voting rights to those Direct Participants to whose
accounts the Book-Entry Notes are credited on the applicable record date
(identified in a listing attached to the Omnibus Proxy).
 
  Principal, premium, if any, and/or interest, if any, payments on the Global
Notes representing the Book-Entry Notes will be made in immediately available
funds to the Depository. The Depository's practice is to credit Director
Participants' accounts on the applicable payment date in accordance with their
respective holdings shown on the Depository's records unless the Depository
has reason to believe that it will not receive payment on such date. Payments
by Participants to Beneficial Owners will be governed by standing instructions
and customary practices, as is the case with securities held for the accounts
of customers in bearer form or registered in "street name", and will be the
responsibility of such Participant and not of the Depository, the Trustee or
the Company, subject to any statutory or regulatory requirements as may be in
effect from time to time. Payment of principal, premium, if any, and/or
interest, if any, to the Depository is the responsibility of the Company and
the Trustee, disbursement of such payments to Direct Participants shall be the
responsibility of the Depository, and
 
                                     S-18
<PAGE>
 
disbursement of such payments to the Beneficial Owners shall be the
responsibility of Direct Participants and Indirect Participants.
 
  If applicable, redemption notices shall be sent to Cede & Co. If less than
all of the Book-Entry Notes of like tenor and terms are being redeemed, the
Depository's practice is to determine by lot the amount of the interest of
each Direct Participant in such issue to be redeemed.
 
  A Beneficial Owner shall give notice of any option to elect to have its
Book-Entry Notes repaid by the Company, through its Participant, to the
Trustee, and shall effect delivery of such Book-Entry Notes by causing the
Direct Participant to transfer the Participant's interest in the Global Note
or Notes representing such Book-Entry Notes, on the Depository's records, to
the Trustee. The requirement for physical delivery of Book-Entry Notes in
connection with a demand for repayment will be deemed satisfied when the
ownership rights in the Global Note or Notes representing such Book-Entry
Notes are transferred by Direct Participants on the Depository's records.
 
  The Depository may discontinue providing its services as securities
depository with respect to the Book-Entry Notes at any time by giving
reasonable notice to the Company or the Trustee. Under such circumstances, in
the event that a successor securities depository is not obtained, Certificated
Notes are required to be printed and delivered.
 
  The Company may decide to discontinue use of the system of book-entry
transfers through the Depository (or a successor securities depository). In
that event, Certificated Notes will be printed and delivered.
 
  The information in this section concerning the Depository and the
Depository's system has been obtained from sources that the Company believes
to be reliable, but the Company takes no responsibility for the accuracy
thereof.
 
  Purchases of Book-Entry Notes must be made by or through Participants, which
will receive a credit on the records of the Depository. The ownership interest
of each actual purchaser of each Book-Entry Note (the "Beneficial Owner") is
in turn to be recorded on the Participants' or Indirect Participants' records.
Beneficial Owners will not receive written confirmation from the Depository of
their purchase, but Beneficial Owners are expected to receive written
confirmations providing details of the transaction, as well as periodic
statements of their holdings, from the Participant or Indirect Participant
through which the Beneficial Owner entered into the transaction. Ownership of
beneficial interests in Global Notes will be shown on, and the transfer of
such ownership interests will be effected only through, records maintained by
the Depository (with respect to interests of Participants) and on the records
of Participants (with respect to interests of persons held through
Participants). The laws of some states may require that certain purchasers of
securities take physical delivery of such securities in definitive form. Such
limits and such laws may impair the ability to own, transfer or pledge
beneficial interests in Global Notes.
 
  So long as the Depository, or its nominee, is the registered owner of a
Global Note, the Depository or its nominee, as the case may be, will be
considered the sole owner or Holder of the Notes represented by such Global
Note for all purposes under the Senior Indenture. Except as provided below,
Beneficial Owners of a Global Note will not be entitled to have the Notes
represented by such Global Note registered in their names, will not receive or
be entitled to receive physical delivery of the Notes in definitive form and
will not be considered the owners or Holders thereof under the 1993 Indenture.
Accordingly, each person owning a beneficial interest in a Global Note must
rely on the procedures of the Depository and, if such person is not a
Participant, on the procedures of the Participant through which such person
owns its interest, to exercise any rights of a Holder under the 1993
Indenture. The Company understands that under existing industry practices, in
the event that the Company requests any action of Holders or that an owner of
a beneficial interest in such a Global Note desires to give or take any action
which a Holder is entitled to give or take under the 1993 Indenture, the
Depository would authorize the Participants holding the relevant beneficial
interests to give or take such action, and such Participants would authorize
Beneficial Owners owning through such Participants to give or take such action
or would otherwise act upon the instructions of Beneficial Owners. Conveyance
of notices and
 
                                     S-19
<PAGE>
 
other communications by the Depository to Participants, by Participants to
Indirect Participants, and by Participants and Indirect Participants to
Beneficial Owners will be governed by arrangements among them, subject to any
statutory or regulatory requirements as may be in effect from time to time.
 
  If (x) the Depository is at any time unwilling or unable to continue as
Depository and a successor depository is not appointed by the Company within
60 days, or (y) the Company executes and delivers to the Trustee a Company
Order to the effect that the Global Notes shall be exchangeable, or (z) an
Event of Default has occurred and is continuing with respect to the Notes, the
Global Note or Global Notes will be exchangeable for Notes in definitive form
of like tenor and of an equal aggregate principal amount, in denominations of
$1,000 and integral multiples thereof. Such definitive Notes shall be
registered in such name or names as the Depository shall instruct the Trustee.
It is expected that such instructions may be based upon directions received by
the Depository from Participants with respect to ownership of beneficial
interests in Global Notes.
 
            CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS
 
  The following summary of certain United States Federal income tax
consequences of the purchase, ownership and disposition of the Notes is based
upon laws, regulations, rulings and decisions now in effect, all of which are
subject to change (including changes in effective dates) or possible differing
interpretations. It deals only with Notes held as capital assets and does not
purport to deal with persons in special tax situations, such as financial
institutions, insurance companies, regulated investment companies, dealers in
securities or currencies, persons holding Notes as a hedge against currency
risks or as a position in a "straddle" for tax purposes, or persons whose
functional currency is not the United States dollar. It also does not deal
with holders other than original purchasers (except where otherwise
specifically noted). Persons considering the purchase of the Notes should
consult their own tax advisors concerning the application of United States
Federal income tax laws to their particular situations as well as any
consequences of the purchase, ownership and disposition of the Notes arising
under the laws of any other taxing jurisdiction.
 
  As used herein, the term "U.S. Holder" means a beneficial owner of a Note
that is for United States Federal income tax purposes (i) a citizen or
resident of the United States, (ii) a corporation, partnership or other entity
created or organized in or under the laws of the United States or of any
political subdivision thereof, (iii) an estate whose income is subject to
United States federal income tax regardless of its source, (iv) a trust if a
court within the United States is able to exercise primary supervision over
the administration of the trust and one or more United States fiduciaries have
the authority to control all substantial decisions of the trust, or (v) any
other person whose income or gain in respect of a Note is effectively
connected with the conduct of a United States trade or business. As used
herein, the term "non-U.S. Holder" means a beneficial owner of a Note that is
not a U.S. Holder.
 
U.S. HOLDERS
 
  "Payments of Interest." Payments of interest on a Note generally will be
taxable to a U.S. Holder as ordinary interest income at the time such payments
are accrued or are received (in accordance with the U.S. Holder's regular
method of tax accounting).
 
  "Original Issue Discount." The following summary is a general discussion of
the United States Federal income tax consequences to U.S. Holders of the
purchase, ownership and disposition of Notes issued with original issue
discount ("Discount Notes"). The following summary is based upon final
Treasury regulations (the "OID Regulations") released by the Internal Revenue
Service ("IRS") on January 27, 1994, as amended on June 11, 1996, under the
original issue discount provisions of the Code.
 
  For United States Federal income tax purposes, original issue discount is
the excess of the stated redemption price at maturity of a Note over its issue
price, if such excess equals or exceeds a "de minimis" amount (generally 1/4 of
1% of the Note's stated redemption price at maturity multiplied by the number
of complete years to its
 
                                     S-20
<PAGE>
 
maturity from its issue date or, in the case of a Note providing for the
payment of any amount other than qualified stated interest (as defined below)
prior to maturity, multiplied by the weighted average maturity of such Note).
The issue price of each Note of an issue of Notes equals the first price at
which a substantial amount of such Notes has been sold (ignoring sales to bond
houses, brokers, or similar persons or organizations acting in the capacity of
underwriters, placement agents, or wholesalers). The stated redemption price
at maturity of a Note is the sum of all payments provided by the Note other
than "qualified stated interest" payments. The term "qualified stated
interest" generally means stated interest that is unconditionally payable in
cash or property (other than debt instruments of the issuer) at least annually
at a single fixed rate. In addition, under the OID Regulations, if a Note
bears interest for one or more accrual periods at a rate below the rate
applicable for the remaining term of such Note ("e.g.", Notes with teaser rates
or interest holidays), and if the greater of either the resulting foregone
interest on such Note or any "true" discount on such Note ("i.e.", the excess of
the Note's stated principal amount over its issue price) equals or exceeds a
specified "de minimis" amount, then the stated interest on the Note would be
treated as original issue discount rather than qualified stated interest.
 
  Payments of qualified stated interest on a Note are taxable to a U.S. Holder
as ordinary interest income at the time such payments are accrued or are
received (in accordance with the U.S. Holder's regular method of tax
accounting). A U.S. Holder of a Discount Note must include original issue
discount in income as ordinary interest for United States Federal income tax
purposes as it accrues under a constant yield method in advance of receipt of
the cash payments attributable to such income, regardless of such U.S.
Holder's regular method of tax accounting. In general, the amount of original
issue discount included in income by the initial U.S. Holder of a Discount
Note is the sum of the daily portions of original issue discount with respect
to such Discount Note for each day during the taxable year (or portion of the
taxable year) on which such U.S. Holder held such Discount Note. The "daily
portion" of original issue discount on any Discount Note is determined by
allocating to each day in any accrual period a ratable portion of the original
issue discount allocable to that accrual period. An "accrual period" may be of
any length and the accrual periods may vary in length over the term of the
Discount Note, provided that each accrual period is no longer than one year
and each scheduled payment of principal or interest occurs either on the final
day of an accrual period or on the first day of an accrual period. The amount
of original issue discount allocable to each accrual period is generally equal
to the difference between (i) the product of the Discount Note's adjusted
issue price at the beginning of such accrual period and its yield to maturity
(determined on the basis of compounding at the close of each accrual period
and appropriately adjusted to take into account the length of the particular
accrual period) and (ii) the amount of any qualified stated interest payments
allocable to such accrual period. The "adjusted issue price" of a Discount
Note at the beginning of any accrual period is the sum of the issue price of
the Discount Note plus the amount of original issue discount allocable to all
prior accrual periods minus the amount of any prior payments on the Discount
Note that were not qualified stated interest payments. Under these rules, U.S.
Holders generally will have to include in income increasingly greater amounts
of original issue discount in successive accrual periods.
 
  A U.S. Holder who purchases a Discount Note for an amount that is greater
than its adjusted issue price as of the purchase date and less than or equal
to the sum of all amounts payable on the Discount Note after the purchase date
other than payments of qualified stated interest, will be considered to have
purchased the Discount Note at an "acquisition premium." Under the acquisition
premium rules, the amount of original issue discount which such U.S. Holder
must include in its gross income with respect to such Discount Note for any
taxable year (or portion thereof in which the U.S. Holder holds the Discount
Note) will be reduced (but not below zero) by the portion of the acquisition
premium properly allocable to the period.
 
  Under the OID Regulations, Floating Rate Notes and Indexed Notes
(hereinafter "Variable Notes") are subject to special rules whereby a Variable
Note will qualify as a "variable rate debt instrument" if (a) its issue price
does not exceed the total noncontingent principal payments due under the
Variable Note by more than a specified "de minimis" amount and (b) it provides
for stated interest, paid or compounded at least annually, at current values
of (i) one or more qualified floating rates, (ii) a single fixed rate and one
or more qualified floating rates, (iii) a single objective rate, or (iv) a
single fixed rate and a single objective rate that is a qualified inverse
floating rate.
 
                                     S-21
<PAGE>
 
  A "qualified floating rate" is any variable rate where variations in the
value of such rate can reasonably be expected to measure contemporaneous
variations in the cost of newly borrowed funds in the currency in which the
Variable Note is denominated. Although a multiple of a qualified floating rate
will generally not itself constitute a qualified floating rate, a variable
rate equal to the product of a qualified floating rate and a fixed multiple
that is greater than .65 but not more than 1.35 will constitute a qualified
floating rate. A variable rate equal to the product of a qualified floating
rate and a fixed multiple that is greater than .65 but not more than 1.35,
increased or decreased by a fixed rate, will also constitute a qualified
floating rate. In addition, under the OID Regulations, two or more qualified
floating rates that can reasonably be expected to have approximately the same
values throughout the term of the Variable Note ("e.g.", two or more qualified
floating rates with values within 25 basis points of each other as determined
on the Variable Note's issue date) will be treated as a single qualified
floating rate. Notwithstanding the foregoing, a variable rate that would
otherwise constitute a qualified floating rate but which is subject to one or
more restrictions such as a maximum numerical limitation ("i.e.", a cap) or a
minimum numerical limitation ("i.e.", a floor) may, under certain circumstances,
fail to be treated as a qualified floating rate under the OID Regulations
unless such cap or floor is fixed throughout the term of the Note. An
"objective rate" is a rate that is not itself a qualified floating rate but
which is determined using a single fixed formula that is based on objective
financial or economic information. A rate will not qualify as an objective
rate if it is based on information that is within the control of the issuer
(or a related party) or that is unique to the circumstances of the issuer (or
a related party), such as dividends, profits, or the value of the issuer's
stock (although a rate does not fail to be an objective rate merely because it
is based on the credit quality of the issuer). A "qualified inverse floating
rate" is any objective rate where such rate is equal to a fixed rate minus a
qualified floating rate, as long as variations in the rate can reasonably be
expected to inversely reflect contemporaneous variations in the qualified
floating rate. The OID Regulations also provide that if a Variable Note
provides for stated interest at a fixed rate for an initial period of one year
or less followed by a variable rate that is either a qualified floating rate
or an objective rate and if the variable rate on the Variable Note's issue
date is intended to approximate the fixed rate ("e.g.", the value of the
variable rate on the issue date does not differ from the value of the fixed
rate by more than 25 basis points), then the fixed rate and the variable rate
together will constitute either a single qualified floating rate or objective
rate, as the case may be.
 
  If a Variable Note that provides for stated interest at either a single
qualified floating rate or a single objective rate throughout the term thereof
qualifies as a "variable rate debt instrument" under the OID Regulations, and
if the interest on such Note is unconditionally payable in cash or property
(other than debt instruments of the issuer) at least annually, then all stated
interest on the Note will constitute qualified stated interest and will be
taxed accordingly. Thus, a Variable Note that provides for stated interest at
either a single qualified floating rate or a single objective rate throughout
the term thereof and that qualifies as a "variable rate debt instrument" under
the OID Regulations will generally not be treated as having been issued with
original issue discount unless the Variable Note is issued at a "true"
discount ("i.e.", at a price below the Note's stated principal amount) in excess
of a specified "de minimis" amount. The amount of qualified stated interest and
the amount of original issue discount, if any, that accrues during an accrual
period on such a Variable Note is determined under the rules applicable to
fixed rate debt instruments by assuming that the variable rate is a fixed rate
equal to (i) in the case of a qualified floating rate or qualified inverse
floating rate, the value as of the issue date, of the qualified floating rate
or qualified inverse floating rate, or (ii) in the case of an objective rate
(other than a qualified inverse floating rate), a fixed rate that reflects the
yield that is reasonably expected for the Variable Note. The qualified stated
interest allocable to an accrual period is increased (or decreased) if the
interest actually paid during an accrual period exceeds (or is less than) the
interest assumed to be paid during the accrual period pursuant to the
foregoing rules.
 
  In general, any other Variable Note that qualifies as a "variable rate debt
instrument" will be converted into an "equivalent" fixed rate debt instrument
for purposes of determining the amount and accrual of original issue discount
and qualified stated interest on the Variable Note. The OID Regulations
generally require that such a Variable Note be converted into an "equivalent"
fixed rate debt instrument by substituting any qualified floating rate or
qualified inverse floating rate provided for under the terms of the Variable
Note with a fixed rate equal to the value of the qualified floating rate or
qualified inverse floating rate, as the case may be, as of the
 
                                     S-22
<PAGE>
 
Variable Note's issue date. Any objective rate (other than a qualified inverse
floating rate) provided for under the terms of the Variable Note is converted
into a fixed rate that reflects the yield that is reasonably expected for the
Variable Note. In the case of a Variable Note that qualifies as a "variable
rate debt instrument" and provides for stated interest at a fixed rate in
addition to either one or more qualified floating rates or a qualified inverse
floating rate, the fixed rate is initially converted into a qualified floating
rate (or a qualified inverse floating rate, if the Variable Note provides for
a qualified inverse floating rate). Under such circumstances, the qualified
floating rate or qualified inverse floating rate that replaces the fixed rate
must be such that the fair market value of the Variable Note as of the
Variable Note's issue date is approximately the same as the fair market value
of an otherwise identical debt instrument that provides for either the
qualified floating rate or qualified inverse floating rate rather than the
fixed rate. Subsequent to converting the fixed rate into either a qualified
floating rate or a qualified inverse floating rate, the Variable Note is then
converted into an "equivalent" fixed rate debt instrument in the manner
described above.
 
  Once the Variable Note is converted into an "equivalent" fixed rate debt
instrument pursuant to the foregoing rules, the amount of original issue
discount and qualified stated interest, if any, are determined for the
"equivalent" fixed rate debt instrument by applying the general original issue
discount rules to the "equivalent" fixed rate debt instrument and a U.S.
Holder of the Variable Note will account for such original issue discount and
qualified stated interest as if the U.S. Holder held the "equivalent" fixed
rate debt instrument. Each accrual period appropriate adjustments will be made
to the amount of qualified stated interest or original issue discount assumed
to have been accrued or paid with respect to the "equivalent" fixed rate debt
instrument in the event that such amounts differ from the actual amount of
interest accrued or paid on the Variable Note during the accrual period.
 
  If a Variable Note does not qualify as a "variable rate debt instrument"
under the OID Regulations, then the Variable Note would be treated as a
contingent payment debt obligation. On June 11, 1996, the Treasury Department
issued final regulations (the "CPDI Regulations") concerning the proper United
States Federal income tax treatment of contingent payment debt instruments. In
general, the CPDI Regulations would cause the timing and character of income,
gain or loss reported on a contingent payment debt instrument to substantially
differ from the timing and character of income, gain or loss reported on a
contingent payment debt instrument under general principles of current United
States Federal income tax law. Specifically, the CPDI Regulations generally
require a U.S. Holder of such an instrument to include future contingent and
noncontingent interest payments in income as such interest accrues based upon
a projected payment schedule. Moreover, in general, under the CPDI
Regulations, any gain recognized by a U.S. Holder on the sale, exchange, or
retirement of a contingent payment debt instrument will be treated as ordinary
income and all or a portion of any loss realized could be treated as ordinary
loss as opposed to capital loss (depending upon the circumstances). The CPDI
Regulations apply to debt instruments issued on or after August 13, 1996. The
proper United States Federal income tax treatment of Variable Notes that are
treated as contingent payment debt obligations will be more fully described in
the applicable Pricing Supplement. Furthermore, any other special United
States Federal income tax considerations, not otherwise discussed herein,
which are applicable to any particular issue of Notes will be discussed in the
applicable Pricing Supplement.
 
  Certain of the Notes (i) may be redeemable at the option of the Company
prior to their stated maturity (a "call option") and/or (ii) may be repayable
at the option of the holder prior to their stated maturity (a "put option").
Notes containing such features may be subject to rules that differ from the
general rules discussed above. Investors intending to purchase Notes with such
features should consult their own tax advisors, since the original issue
discount consequences will depend, in part, on the particular terms and
features of the purchased Notes.
 
  U.S. Holders may generally, upon election, include in income all interest
(including stated interest, acquisition discount, original issue discount, "de
minimis" original issue discount, market discount, "de minimis" market discount,
and unstated interest, as adjusted by any amortizable bond premium or
acquisition premium) that accrues on a debt instrument by using the constant
yield method applicable to original issue discount, subject to certain
limitations and exceptions.
 
                                     S-23
<PAGE>
 
  "Foreign-Currency Notes." The United States Federal income tax consequences of
the purchase, ownership and disposition of Notes providing for payments
denominated in a currency other than U.S. dollars will be more fully described
in the applicable Pricing Supplement.
 
  "Short-Term Notes." Notes that have a fixed maturity of one year or less
("Short-Term Notes") will be treated as having been issued with original issue
discount. In general, an individual or other cash method U.S. Holder is not
required to accrue such original issue discount unless the U.S. Holder elects
to do so. If such an election is not made, any gain recognized by the U.S.
Holder on the sale, exchange or maturity of the Short-Term Note will be
ordinary income to the extent of the original issue discount accrued on a
straight-line basis, or upon election under the constant yield method (based
on daily compounding), through the date of sale or maturity, and a portion of
the deductions otherwise allowable to the U.S. Holder for interest on
borrowings allocable to the Short-Term Note will be deferred until a
corresponding amount of income is realized. U.S. Holders who report income for
United States Federal income tax purposes under the accrual method, and
certain other holders including banks and dealers in securities, are required
to accrue original issue discount on a Short-Term Note on a straight-line
basis unless an election is made to accrue the original issue discount under a
constant yield method (based on daily compounding).
 
  "Market Discount." If a U.S. Holder purchases a Note, other than a Discount
Note, for an amount that is less than its issue price (or, in the case of a
subsequent purchaser, its stated redemption price at maturity) or, in the case
of a Discount Note, for an amount that is less than its adjusted issue price
as of the purchase date, such U.S. Holder will be treated as having purchased
such Note at a "market discount," unless such market discount is less than a
specified "de minimis" amount.
 
  Under the market discount rules, a U.S. Holder will be required to treat any
partial principal payment (or, in the case of a Discount Note, any payment
that does not constitute qualified stated interest) on, or any gain realized
on the sale, exchange, retirement or other disposition of, a Note as ordinary
income to the extent of the lesser of (i) the amount of such payment or
realized gain or (ii) the market discount which has not previously been
included in income and is treated as having accrued on such Note at the time
of such payment or disposition. Market discount will be considered to accrue
ratably during the period from the date of acquisition to the maturity date of
the Note, unless the U.S. Holder elects to accrue market discount on the basis
of semiannual compounding.
 
  A U.S. Holder may be required to defer the deduction of all or a portion of
the interest paid or accrued on any indebtedness incurred or maintained to
purchase or carry a Note with market discount until the maturity of the Note
or certain earlier dispositions, because a current deduction is only allowed
to the extent the interest expense exceeds an allocable portion of market
discount. A U.S. Holder may elect to include market discount in income
currently as it accrues (on either a ratable or semiannual compounding basis),
in which case the rules described above regarding the treatment as ordinary
income of gain upon the disposition of the Note and upon the receipt of
certain cash payments and regarding the deferral of interest deductions will
not apply. Generally, such currently included market discount is treated as
ordinary interest for United States Federal income tax purposes. Such an
election will apply to all debt instruments acquired by the U.S. Holder on or
after the first day of the taxable year to which such election applies and may
be revoked only with the consent of the IRS.
 
  "Premium." If a U.S. Holder purchases a Note for an amount that is greater
than the sum of all amounts payable on the Note after the purchase date other
than payments of qualified stated interest, such U.S Holder will be considered
to have purchased the Note with "amortizable bond premium" equal in amount to
such excess. A U.S. Holder may elect to amortize such premium using a constant
yield method over the remaining term of the Note and may offset interest
otherwise required to be included in respect of the Note during any taxable
year by the amortized amount of such excess for the taxable year. However, if
the Note may be optionally redeemed after the U.S. Holder acquires it at a
price in excess of its stated redemption price at maturity, special rules
would apply which could result in a deferral of the amortization of some bond
premium until later in the term of the Note. Any election to amortize bond
premium applies to all taxable debt obligations then owned and thereafter
acquired by the U.S. Holder and may be revoked only with the consent of the
IRS.
 
                                     S-24
<PAGE>
 
  "Disposition of a Note." Except as discussed above, upon the sale, exchange or
retirement of a Note, a U.S. Holder generally will recognize taxable gain or
loss equal to the difference between the amount realized on the sale, exchange
or retirement (other than amounts representing accrued and unpaid interest)
and such U.S. Holder's adjusted tax basis in the Note. A U.S. Holder's
adjusted tax basis in a Note generally will equal such U.S. Holder's initial
investment in the Note increased by any original issue discount included in
income (and accrued market discount, if any, if the U.S. Holder has included
such market discount in income) and decreased by the amount of any payments,
other than qualified stated interest payments, received and amortizable bond
premium taken with respect to such Note. Such gain or loss generally will be
long-term capital gain or loss if the Note were held for more than one year.
 
NON-U.S. HOLDERS
 
  A non-U.S. Holder will not be subject to United States Federal income taxes
on payments of principal, premium (if any) or interest (including original
issue discount, if any) on a Note, unless such non-U.S. Holder is a direct or
indirect 10% or greater shareholder of the Company, a controlled foreign
corporation related to the Company or a bank receiving interest described in
section 881(c)(3)(A) of the Code. To qualify for the exemption from taxation,
the last United States payor in the chain of payment prior to payment to a
non-U.S. Holder (the "Withholding Agent") must have received in the year in
which a payment of interest or principal occurs, or in either of the two
preceding calendar years, a statement that (i) is signed by the beneficial
owner of the Note under penalties of perjury, (ii) certifies that such owner
is not a U.S. Holder and (iii) provides the name and address of the beneficial
owner. The statement may be made on an IRS Form W-8 or a substantially similar
form, and the beneficial owner must inform the Withholding Agent of any change
in the information on the statement within 30 days of such change. If a Note
is held through a securities clearing organization or certain other financial
institutions, the organization or institution may provide a signed statement
to the Withholding Agent. However, in such case, the signed statement must be
accompanied by a copy of the IRS Form W-8 or the substitute form provided by
the beneficial owner to the organization or institution. The Treasury
Department is considering implementation of further certification requirements
aimed at determining whether the issuer of a debt obligation is related to
holders thereof.
 
  Generally, a non-U.S. Holder will not be subject to United States Federal
income taxes on any amount which constitutes capital gain upon retirement or
disposition of a Note, provided the gain is not effectively connected with the
conduct of a trade or business in the United States by the non-U.S. Holder.
Certain other exceptions may be applicable, and a non-U.S. Holder should
consult its tax advisor in this regard.
 
  The Notes will not be includible in the estate of a non-U.S. Holder unless
the individual is a direct or indirect 10% or greater shareholder of the
Company or, at the time of such individual's death, payments in respect of the
Notes would have been effectively connected with the conduct by such
individual of a trade or business in the United States.
 
BACKUP WITHHOLDING
 
  Backup withholding of United States Federal income tax at a rate of 31% may
apply to payments made in respect of the Notes to registered owners who are
not "exempt recipients" and who fail to provide certain identifying
information (such as the registered owner's taxpayer identification number) in
the required manner. Generally, individuals are not exempt recipients, whereas
corporations and certain other entities generally are exempt recipients.
Payments made in respect of the Notes to a U.S. Holder must be reported to the
IRS, unless the U.S. Holder is an exempt recipient or establishes an
exemption. Compliance with the identification procedures described in the
preceding section would establish an exemption from backup withholding for
those non-U.S. Holders who are not exempt recipients.
 
  In addition, upon the sale of a Note to (or through) a broker, the broker
must withhold 31% of the entire purchase price, unless either (i) the broker
determines that the seller is a corporation or other exempt recipient or (ii)
the seller provides, in the required manner, certain identifying information
and, in the case of a non-U.S.
 
                                     S-25
<PAGE>
 
Holder, certifies that such seller is a non-U.S. Holder (and certain other
conditions are met). Such a sale must also be reported by the broker to the
IRS, unless either (i) the broker determines that the seller is an exempt
recipient or (ii) the seller certifies its non-U.S. status (and certain other
conditions are met). Certification of the registered owner's non-U.S. status
would be made normally on an IRS Form W-8 under penalties of perjury, although
in certain cases it may be possible to submit other documentary evidence.
 
  Any amounts withheld under the backup withholding rules from a payment to a
beneficial owner would be allowed as a refund or a credit against such
beneficial owner's United States Federal income tax provided the required
information is furnished to the IRS.
 
                             PLAN OF DISTRIBUTION
 
  The Notes are being offered on a continuing basis for sale by the Company,
through the Agent, Merrill Lynch & Co., Merrill Lynch, Pierce, Fenner & Smith
Incorporated, who will purchase the Notes, as principal, from the Company, for
resale to investors and other purchasers at varying prices relating to
prevailing market prices at the time of resale as determined by the Agent, or,
if so specified in an applicable Pricing Supplement, for resale at a fixed
public offering price. Unless otherwise specified in an applicable Pricing
Supplement, any Note sold to the Agent as principal will be purchased by the
Agent at a price equal to 100% of the principal amount thereof less a
percentage of the principal amount equal to the commission applicable to an
agency sale (as described below) of a Note of identical maturity. If agreed to
by the Company and the Agent, the Agent may utilize its reasonable efforts on
an agency basis to solicit offers to purchase the Notes at 100% of the
principal amount thereof, unless otherwise specified in an applicable Pricing
Supplement. The Company will pay a commission to the Agent, ranging from .125%
to .750% of the principal amount of a Note, depending upon its Stated Maturity
(or, with respect to Notes for which the Stated Maturity is in excess of 30
years, such commission as shall be agreed upon by the Company and the Agent at
the time of sale), sold through the Agent.
 
  The Agent may sell Notes it has purchased from the Company as principal to
other dealers for resale to investors, and may allow any portion of the
discount received in connection with such purchases from the Company to such
dealers. After the initial public offering of Notes, the public offering price
(in the case of Notes to be resold at a fixed public offering price), the
concession and the discount allowed to dealers may be changed.
 
  The Company reserves the right to withdraw, cancel or modify the offer made
hereby without notice and may reject orders in whole or in part whether placed
directly with the Company or through the Agent. The Agent will have the right,
in its discretion reasonably exercised, to reject in whole or in part any
offer to purchase Notes received by the Agent.
 
  Unless otherwise specified in an applicable Pricing Supplement, payment of
the purchase price of the Notes will be required to be made in immediately
available funds in New York City on the date of settlement.
 
  No Note will have an established trading market when issued. Unless
specified in the applicable Pricing Supplement, the Notes will not be listed
on any securities exchange. The Agent may from time to time purchase and sell
Notes in the secondary market, but the Agent is not obligated to do so, and
there can be no assurance that there will be a secondary market for the Notes
or liquidity in the secondary market if one develops. From time to time, the
Agent may make a market in the Notes.
 
  The Agent may be deemed to be an "underwriter" within the meaning of the
Securities Act of 1933, as amended (the "Act"). The Company has agreed to
indemnify the Agent against or to make contributions relating to certain civil
liabilities, including liabilities under the Act, or to contribute to payments
the Agent may be required to make in respect thereof. The Company has agreed
to reimburse the Agent for certain expenses.
 
  From time to time, the Company may issue and sell other Securities described
in the accompanying Prospectus, and the amount of Notes offered hereby is
subject to reduction as a result of such sales.
 
 
                                     S-26
<PAGE>
 
  In connection with the offering of Notes purchased by the Agent as principal
on a fixed price basis, the Agent is permitted to engage in certain
transactions that stabilize the price of the Notes. Such transactions may
consist of bids or purchases for the purpose of pegging, fixing or maintaining
the price of the Notes. If the Agent creates a short position in the Notes in
connection with the offering ("i.e.", if it sells Notes in an aggregate
principal amount exceeding that set forth in the applicable Pricing
Supplement), then the Agent may reduce that short position by purchasing Notes
in the open market.
 
  In general, purchases of Notes for the purpose of stabilization or to reduce
a short position could cause the price of the Notes to be higher than in the
absence of such purchases.
 
  Neither the Company nor the Agent make any representation or prediction as
to the direction or magnitude of any effect that the transactions described
above may have on the price of the Notes. In addition, neither the Company nor
the Agent makes any representation that the Agent will engage in any such
transactions or that such transactions, once commenced, will not be
discontinued without notice.
 
  The distribution of the Notes will conform to the requirements set forth in
the applicable sections of Rule 2720 of the Conduct Rules of the National
Association of Securities Dealers, Inc.
 
                                 LEGAL OPINION
 
  The validity of the Notes will be passed upon for the Company and the Agent
by Brown & Wood LLP, New York, New York.

                SUBJECT TO COMPLETION, ISSUE DATE:  JUNE 4, 1997
PROSPECTUS


                           MERRILL LYNCH & CO., INC.
                               MEDIUM-TERM NOTES

  Merrill Lynch & Co., Inc. (the "Company'') has issued Medium-Term Notes with
original maturities from and exceeding 9 months from date of issue (the
"Notes'') pursuant to an indenture, dated as of April 1, 1983, as amended and
restated, between the Company and The Chase Manhattan Bank, formerly known as
Chemical Bank (successor to Manufacturers Hanover Trust Company). The Notes bear
interest at fixed or variable rates, or were sold at a discount and do not bear
interest. The descriptions of the interest rates on Fixed Rate Notes, the method
of determining the interest rates on Floating Rate Notes, the issue prices of
Zero Coupon Notes, the currencies (if other than U.S. dollars) in which Notes
were denominated and the dates of maturity and other terms related to specific
issues of Notes are set forth in Pricing Supplements relating to each such issue
of Notes that were previously filed by the Company with the Securities and
Exchange Commission pursuant to regulations promulgated under the Securities Act
of 1933. Such Pricing Supplements are hereby incorporated by reference into this
Prospectus and are available at the reference facilities maintained by the
Securities and Exchange Commission specified in the section entitled "Available
Information'' contained in this Prospectus. The Notes had original maturities
from and exceeding 9 months from their respective dates of original issue. The
Notes were issued in the form of a certificate issued in definitive form.

  Floating Rate Notes and Zero Coupon Notes were issued in denominations of
$25,000 or any amount in excess thereof which is an integral multiple of $1,000.
Fixed Rate Notes were issued in denominations of $1,000 or any integral multiple
in excess thereof.

  Unless otherwise specified in the applicable Pricing Supplement, interest on
Fixed Rate Notes will be payable semi-annually on each May 15 and November 15
and at maturity or, if applicable, upon redemption or optional repayment. The
interest rate on Floating Rate Notes will be determined by reference to a
specified interest rate formula, and may be adjusted by a "Spread'' or "Spread
Multiplier'', as defined herein. Interest on each Floating Rate Note will be

                              DESCRIPTION OF NOTES


GENERAL

  "Pricing Supplement'', as used herein, means a prospectus supplement relating
to an individual issue of the Notes, as filed with the Commission.

  The terms and conditions set forth below apply to each Note unless otherwise
specified in the applicable Pricing Supplement.

                                       3
                                                                       
<PAGE>
 
  Except as provided in the applicable Pricing Supplement, the Notes are
denominated in U.S. dollars. If provided in the applicable Pricing Supplement,
Notes may be denominated in a foreign currency or in units of two or more
currencies ("Multi-Currency Notes").

  Except as provided in the applicable Pricing Supplement, (i) the Notes were
issued only in fully registered form without coupons, (ii) Floating Rate Notes
and Zero Coupon Notes were issued in denominations of $25,000 or any amount in
excess thereof which is an integral multiple of $1,000, and (iii) Fixed Rate
Notes were issued in denominations of $1,000 or any integral multiple in excess
thereof.

  Unless otherwise specified in the applicable Pricing Supplement, principal and
interest, if any, will be payable, the transfer of the Notes will be
registrable, and Notes will be exchangeable for Notes bearing identical terms
and provisions at the office of the Trustee in The City of New York designated
for such purpose, provided that payment of interest, other than interest payable
at maturity (or on any date of redemption or repayment), may be made at the
option of the Company by check mailed to the address of the person entitled
thereto as shown on the Security Register. The principal and interest payable at
maturity or the date of redemption or repayment on each Note will be paid upon
maturity, redemption or repayment, as the case may be, in immediately available
funds against presentation of the Note at the office of the Trustee maintained
for such purpose.

  Notwithstanding the above, however, payment of interest on a Note which bears
interest at a floating rate (a "Floating Rate Note") at maturity or earlier
redemption or repayment may be made by wire transfer of immediately available
funds to a designated account maintained in the United States upon (i) receipt
of written notice by the Senior Debt Trustee from the Holder thereof not less
than one Business Day prior to the due date of such principal payment and (ii)
presentation of such Note at the Corporate Trust Office of the Senior Debt
Trustee in the Borough of Manhattan, The City of New York (the "Corporate Trust
Office"), or at such other place as the Company may designate. A Holder of not
less than $1,000,000 aggregate principal amount of Floating Rate Notes may by
written notice to the Senior Debt Trustee at the Corporate Trust Office (or at
such other address as the Company will give notice in writing) not less than 15
days prior to an Interest Payment Date, arrange to have the interest payable on
all Notes held by such Holder on such Interest Payment Date, and all subsequent
Interest Payment Dates until written notice to the contrary is given to the
Senior Debt Trustee, made by wire transfer of immediately available funds to a
designated account maintained in the United States.

  Except as provided in the applicable Pricing Supplement, "Business Day" means
any day that is not a Saturday or Sunday and that, in The City of New York, is
neither a legal holiday nor a day on which banking institutions are authorized
or obligated by law or regulation to close.


REPAYMENT AT OPTION OF HOLDER

  If so indicated in an applicable Pricing Supplement, Notes will be repayable
by the Company in whole or in part at the option of the Holders thereof on their
respective Optional Repayment Dates specified in such Pricing Supplement. If no
Optional Repayment Date is indicated with respect to a Note, such Note will not
be repayable at the option of the Holder prior to maturity. Any repayment in
part will be in increments of $1,000 provided that any remaining principal
amount of such Note will be an authorized denomination of such Note. The
repurchase price for any Note so repurchased will be 100% of the principal
amount to be repaid, together with interest thereon payable to the date of
repayment.

  Notwithstanding anything to the contrary herein, if repayable at the option of
the Holder, a Note shall be repayable only on an Interest Payment Date, and if
any Optional Repayment Date specified with respect to a Note would not be an
Interest Payment Date (whether because such date is not a Business Day or
otherwise), such Optional Repayment Date shall (instead of being the date so
specified) be the Interest Payment Date nearest such specified Optional
Repayment Date (whether such Interest Payment Date shall precede or succeed such
specified Optional Repayment Date), or, in the event that an equal number of
days shall separate a specified Optional Repayment Date and the preceding
Interest Payment Date, on the one hand, and the succeeding Interest Payment
Date, on the other hand, such Optional Repayment Date shall be the succeeding
Interest Payment Date.

  In order for a Note which is by its terms repayable at the option of the
Holder to be repaid, prior to maturity, the Company must receive at the
Corporate Trust Office of the Senior Debt Trustee (or at such other address of
which the Company will from time to time notify the Holder thereof) during the
period from and including the 20th Business Day preceding the applicable
Optional Repayment Date up to and including the close of business on the 16th
Business Day preceding the applicable Optional Repayment Date: (i) such Note
with the information under the caption "Option to Elect

                                       4
<PAGE>
 
Repayment" duly completed, or (ii) a telegram, telex, facsimile transmission or
letter from a member of a national securities exchange or the National
Association of Securities Dealers, Inc. or a commercial bank or a trust company
in the United States of America dated no later than the 16th Business Day
preceding the applicable Optional Repayment Date and setting forth the name of
the Holder of such Note, the principal amount of such Note, the amount of such
Note to be repaid, a statement that the option to elect repayment is being
exercised thereby and a guarantee that such Note (with the information required
under the caption "Option to Elect Repayment" duly completed) will be received
at the above-mentioned office of the Senior Debt Trustee, not later than the 5th
Business Day after the date of such telegram, telex, facsimile transmission or
letter and Note, duly completed, is received at such office of the Trustee by
such 5th Business Day. Effective exercise of the repayment option by the Holder
of a Note will be irrevocable. No transfer or exchange of a Note (or, in the
event that a Note is to be repaid in part, such portion of such Note to be
repaid) will be permitted after exercise of the repayment option. All questions
as to the validity, eligibility (including time of receipt) and acceptance of
any Note for repayment will be determined by the Company, whose determination
will be final, binding and non-appealable. The Company has the right to offer
for resale any Note acquired by it pursuant to the foregoing arrangements.
Accordingly, the indebtedness evidenced by any Note so repurchased by the
Company may not be satisfied by such repurchase.


REDEMPTION AT OPTION OF THE COMPANY

  The Notes do not have a sinking fund but are redeemable at the option of the
Company only if a Redemption Date is specified therein and in the applicable
Pricing Supplement. If so indicated in an applicable Pricing Supplement, such
Notes will be subject to redemption by the Company on and after their respective
Redemption Dates specified in such Pricing Supplement. On and after the
Redemption Date, if any, the related Note will be redeemable in whole or in part
in increments of $1,000 (provided that any remaining principal amount of such
Note shall be an authorized denomination of such Note) at the option of the
Company at a redemption price equal to 100% of the principal amount to be
redeemed, together with interest thereon payable to the date of redemption, on
notice given not more than 60 nor less than 30 days prior to the date of
redemption in the case of Fixed Rate Notes, or on notice given not more than 30
nor less than 15 days prior to the date of redemption in the case of Floating
Rate Notes. Notwithstanding the above, however, Floating Rate Notes, if
redeemable at the option of the Company, will be redeemable only on Interest
Payment Dates occurring on or after the applicable Redemption Dates.


INTEREST RATE

  Each Floating Rate Note and Note which bears interest at a fixed rate (a
"Fixed Rate Note'') will bear interest at the rate per annum, or pursuant to the
interest rate formula, stated therein and in the applicable Pricing Supplement
until the principal thereof is paid or made available for payment. Interest will
be payable on each Interest Payment Date and at maturity or, if applicable, upon
redemption or repayment. Interest will be payable to the person in whose name a
Note is registered at the close of business on the Regular Record Date next
preceding each Interest Payment Date; provided, however, interest payable at
maturity or, if applicable, upon redemption or repayment will be payable to the
person to whom principal shall be payable. Except as provided in the applicable
Pricing Supplement, Merrill Lynch, Pierce, Fenner & Smith Incorporated will be
the calculation agent (the "Calculation Agent") with respect to Floating Rate
Notes.

  Each Floating Rate Note will bear interest at rates determined by reference to
an interest rate formula, which may be adjusted by a Spread or Spread Multiplier
(each as defined below), unless otherwise specified therein. A Floating Rate
Note may also have either or both of the following: (i) a maximum limitation, or
ceiling, on the rate at which interest which may accrue during any interest
period; and (ii) a minimum limitation, or floor, on the rate at which interest
which may accrue during any interest period. The applicable Pricing Supplement
relating to Fixed Rate Notes or Floating Rate Notes will designate either a
fixed rate of interest per annum payable on the applicable Note, in which case
such Note will be a Fixed Rate Note, or one of the following Base Rates, as
applicable to the relevant Floating Rate Note: (a) the Commercial Paper Index
Rate, in which case such Note will be a Commercial Paper Index Rate Note, (b)
the Federal Funds Rate, in which case such Note will be a Federal Funds Rate
Note, (c) the Prime Rate, in which case such Note will be a Prime Rate Note, (d)
the Treasury Index Rate, in which case such Note will be a Treasury Index Rate
Note, (e) LIBOR, in which case such Note will be a LIBOR Note, or (f) such other
interest rate formula as is set forth in such Pricing Supplement. Except as
specified in the applicable Pricing Supplement, Floating Rate Notes will have
daily, weekly, monthly, quarterly, semiannual or annual resets of the rate of
interest.

                                       5
<PAGE>
 
FIXED RATE NOTES

  Each Fixed Rate Note will bear interest at the rate per annum stated on the
face thereof until the principal thereof is paid or made available for payment.
Except as provided in the applicable Pricing Supplement, interest will be
payable semi-annually on May 15 and November 15 of each year and at maturity (or
on the date of redemption or repayment, if a Fixed Rate Note is redeemed by the
Company or repaid at the Holder's option prior to maturity). Interest will be
computed on the basis of a 360-day year of twelve 30-day months. Interest will
be payable to the person in whose name a Fixed Rate Note is registered at the
close of business on the May 1 or November 1 Regular Record Date next preceding
the May 15 or November 15 Interest Payment Date. Interest rates are subject to
change by the Company from time to time, but no such change will affect any
Fixed Rate Note theretofore issued or as to which an offer to purchase has been
accepted by the Company.

  Any payment of principal or interest required to be made on an Interest
Payment Date, at maturity or earlier redemption or repayment of a Fixed Rate
Note which is not a Business Day need not be made on such day, but may be made
on the next succeeding Business Day with the same force and effect as if made on
the Interest Payment Date, maturity date or date of redemption or repayment, as
the case may be, and no interest shall accrue with respect to such payment for
the period from and after such Interest Payment Date, maturity date or date of
redemption or repayment.


FLOATING RATE NOTES

  The applicable Pricing Supplement specifies the base rate or other interest
rate formula and the Spread or Spread Multiplier, if any, and the maximum or
minimum interest rate limitation, if any, applicable to each Floating Rate Note.
In addition, such Pricing Supplement specifies for each Floating Rate Note the
following terms, if applicable: the Initial Interest Rate, the Interest Payment
Dates, the Index Maturity, Interest Reset Dates, Optional Repayment Dates,
Redemption Date and any other variable term applicable to such Note.

  The interest rate on each Floating Rate Note will be calculated by reference
to the specified interest rate formula (i) plus or minus the Spread, if any, or
(ii) multiplied by the Spread Multiplier, if any. The "Spread" is the number of
basis points specified in the applicable Pricing Supplement as being applicable
to the interest rate for such Floating Rate Note. The "Spread Multiplier" is
the percentage of the Base Rate applicable to the interest rate for such
Floating Rate Note. "Index Maturity" means, with respect to a Floating Rate
Note, the period to maturity of the instrument or obligation on which the
interest rate formula is based, as specified in the applicable Pricing
Supplement. "Regular Record Date" with respect to Floating Rate Notes means the
15th day (whether or not a Business Day) prior to the applicable Interest
Payment Date. The "Calculation Date", if applicable, with respect to any
Interest Determination Date (as specified with respect to each Base Rate) will
be the earlier of (i) the tenth calendar day after such Interest Determination
Date or, if such day is not a Business Day, the next succeeding Business Day, or
(ii) the Business Day prior to the Interest Payment Date on which such accrued
interest will be payable.

  Except as otherwise provided herein with respect to LIBOR Notes or in the
applicable Pricing Supplement, if any Interest Reset Date for any Floating Rate
Note would otherwise be a day that is not a Business Day, such Interest Reset
Date shall be postponed to the next succeeding day that is a Business Day.

  Each Floating Rate Note will bear interest from the date of issue at the rates
determined as described below until the principal thereof is paid or otherwise
made available for payment. The rate of interest on a Floating Rate Note will be
reset each Interest Reset Date applicable to such Note; provided, however, that
except in the case of Floating Rate Notes which reset daily, the interest rate
in effect for the ten days immediately prior to maturity, redemption or
repayment, as the case may be, will be that in effect on the tenth day preceding
such maturity, redemption or repayment, as the case may be. Except as otherwise
provided herein or in the applicable Pricing Supplement, the rate of interest
determined on an Interest Reset Date with respect to a Floating Rate Note will
be applicable on and after such Interest Reset Date to, but not including, the
next succeeding Interest Reset Date, or until the date of maturity or date of
redemption or repayment, as the case may be.

  If an Interest Payment Date with respect to any Floating Rate Note would
otherwise fall on a day that is not a Business Day with respect to such Note,
such Interest Payment Date will be the following day that is a Business Day,
except that in the case of a LIBOR Note, if such day falls in the next calendar
month, such Interest Payment Date will be the preceding day that is a Business
Day. If the maturity date (or date of redemption or repayment) of any Floating
Rate Note would fall on a day that is not a Business Day, the payment of
interest and principal may be made on the next succeeding Business Day,

                                       6
<PAGE>
 
and no interest on such payment will accrue for the period from and after the
maturity date (or the date of redemption or repayment).

  Except as provided in the applicable Pricing Supplement, interest payments on
Floating Rate Notes shall be the amount of interest accrued from, and including,
the next preceding Interest Payment Date in respect of which interest has been
paid to, but excluding, the Interest Payment Date. With respect to a Floating
Rate Note, accrued interest from the last date to which interest has been paid
is calculated by multiplying the principal amount of such Floating Rate Note by
an accrued interest factor. Such accrued interest factor is computed by adding
the interest factors, calculated for each day, from the last date to which
interest has been paid, to the date for which accrued interest is being
calculated. The interest factor for each such day is computed by dividing the
interest rate applicable to such day by 360, in the case of Commercial Paper
Index Rate Notes, Federal Funds Rate Notes, Prime Rate Notes and LIBOR Notes, or
by the actual number of days in the year, in the case of Treasury Index Rate
Notes.

  All percentages resulting from any calculation on Floating Rate Notes 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) being rounded to 9.87655% (or .0987655)), and all
dollar amounts used in or resulting from such calculation on Floating Rate Notes
will be rounded to the nearest cent (with one-half cent being rounded upward).

  Upon the request of the holder of any Floating Rate Note, the Calculation
Agent will provide the interest rate then in effect and, if determined, the
interest rate which will become effective as a result of a determination made
with respect to the most recent Interest Determination Date with respect to such
Floating Rate Note.


COMMERCIAL PAPER INDEX RATE NOTES

  Commercial Paper Index Rate Notes will bear interest at the interest rates
(calculated with reference to the Commercial Paper Index Rate and the Spread or
Spread Multiplier, if any) specified in the applicable Pricing Supplement.

  Unless otherwise indicated in the applicable Pricing Supplement, "Commercial
Paper Index Rate" means, with respect to any Interest Determination Date
relating to a Commercial Paper Index Rate Note, the Money Market Yield
(calculated as described below) of the rate on that date for commercial paper
having the Index Maturity specified in the applicable Pricing Supplement as such
rate is published by the Board of Governors of the Federal Reserve System in
"Statistical Release H.15(519), Selected Interest Rates" or any successor
publication of the Board of Governors of the Federal Reserve System
("H.15(519)"), under the heading "Commercial Paper". In the event that such
rate is not published by 9:00 A.M. New York City time on the Calculation Date
pertaining to such Interest Determination Date, then the Commercial Paper Index
Rate shall be the Money Market Yield of the rate on that Interest Determination
Date for commercial paper having such Index Maturity as published by the Federal
Reserve Bank of New York in its daily statistical release, "Composite 3:30 P.M.
Quotations for U.S. Government Securities" ("Composite Quotations") under the
heading "Commercial Paper". If by 3:00 P.M., New York City time, on such
Calculation Date such rate is not yet published in either H.15(519) or Composite
Quotations, the Commercial Paper Index Rate for that Interest Determination Date
shall be calculated by the Calculation Agent and shall be the Money Market Yield
of the arithmetic mean of the offered rates of three leading dealers of
commercial paper in The City of New York selected by the Calculation Agent as of
11:00 A.M., New York City time, on that Interest Determination Date for
commercial paper having the specified Index Maturity placed for an industrial
issuer whose bond rating is "AA" or the equivalent from a nationally recognized
rating agency; provided, however, that if the dealers selected as aforesaid by
the Calculation Agent are not quoting as mentioned in this sentence, the
Commercial Paper Index Rate will be the Commercial Paper Index Rate in effect on
such Interest Determination Date.

  "Money Market Yield" shall be the yield (expressed as a percentage)
calculated in accordance with the following formula:

                        Money Market Yield   =     D  X 360    X 100
                                                 -------------         
                                                 360 - (D X M)

where "D" refers to the per annum rate for commercial paper quoted on a bank
discount basis and expressed as a decimal; and "M" refers to the actual number
of days in the interest period for which interest is being calculated.

   The Interest Determination Date pertaining to an Interest Reset Date on a
Commercial Paper Index Rate Note will be the Business Day prior to such Interest
Reset Date.

                                       7
<PAGE>
 
FEDERAL FUNDS RATE NOTES

  Federal Funds Rate Notes will bear interest at the interest rates (calculated
with reference to the Federal Funds Rate and the Spread, or Spread Multiplier,
if any) specified in the applicable Pricing Supplement.

  Unless otherwise indicated in the applicable Pricing Supplement, "Federal
Funds Rate" means, with respect to any Interest Determination Date relating to
a Federal Funds Rate Note, the rate on such Interest Determination Date for
Federal Funds as published by the Board of Governors of the Federal Reserve
System in "Statistical Release H.15(519), Selected Interest Rates"
("H.15(519)") or any successor publication under the heading "Federal Funds
(Effective)" or, if not so published by 9:00 A.M., New York City time, on the
Calculation Date pertaining to such Interest Determination Date, the Federal
Funds Rate will be the interest rate on such Interest Determination Date as
published by the Federal Reserve Bank of New York in its daily statistical
release, "Composite 3:30 P.M. Quotations for U.S. Government Securities"
("Composite Quotations") under the heading "Federal Funds/Effective Rate". If
such rate is not yet published by 9:00 A.M. on the Calculation Date pertaining
to such Interest Determination Date, the Federal Funds Rate for such Interest
Determination Date will be the rate on such Interest Determination Date made
publicly available by the Federal Reserve Bank of New York which is equivalent
to the rate which appears in H.15(519) under the heading "Federal Funds
(Effective)"; provided, however, that if such rate is not made publicly
available by the Federal Reserve Bank of New York by 9:00 A.M. on the
Calculation Date, the Federal Funds Rate will be the last Federal Funds Rate in
effect prior to such Interest Determination Date.

  The rate of interest on a Federal Funds Rate Note will be reset each Interest
Reset Date applicable to such Note. Unless otherwise specified in the applicable
Pricing Supplement, with respect to Federal Funds Rate Notes, each Business Day
will be an Interest Reset Date. The Interest Determination Date pertaining to an
Interest Reset Date on a Federal Funds Rate Note will be the Business Day prior
to such Interest Reset Date.


PRIME RATE NOTES

  Prime Rate Notes will bear interest at the interest rates (calculated with
reference to the Prime Rate and the Spread, or Spread Multiplier, if any)
specified in the applicable Pricing Supplement.

  Unless otherwise indicated in the applicable Pricing Supplement, "Prime Rate"
means, with respect to any Interest Determination Date relating to a Prime Rate
Note, the arithmetic mean of the prime rates quoted on the basis of the actual
number of days in the year divided by a 360-day year as of the close of business
on such Interest Determination Date by three major money center banks in The
City of New York selected by the Calculation Agent. If fewer than three
quotations are provided, the Prime Rate shall be calculated by the Calculation
Agent and shall be determined as the arithmetic mean on the basis of the prime
rates quoted in The City of New York on such date by three substitute banks or
trust companies organized and doing business under the laws of the United
States, or any State thereof, and unaffiliated with the Company, having total
equity capital of at least $500 million and being subject to supervision or
examination by a Federal or State authority, selected by the Calculation Agent;
provided, however, that if the substitute banks or trust companies selected as
aforesaid by the Calculation Agent are not quoting as mentioned in this
sentence, the Prime Rate will be the Prime Rate in effect on such Interest
Determination Date relating to a Prime Rate Note.

  The Interest Determination Date pertaining to an Interest Reset Date on a
Prime Rate Note will be the Business Day prior to such Interest Reset Date.


LIBOR NOTES

  LIBOR Notes will bear interest at the interest rates (calculated with
reference to LIBOR and the Spread or Spread Multiplier, if any) specified in the
applicable Pricing Supplement.

  Unless otherwise indicated in the applicable Pricing Supplement, LIBOR with
respect to any Interest Determination Date relating to a LIBOR Note will equal
the arithmetic mean (as determined by the Calculation Agent) of the offered
rates which appear as of 11:00 A.M., London time, on the Reuters Screen LIBOR
Page on the Reuter Monitor Money Rates Service for deposits (in United States
dollars for the period of the Index Maturity specified in the applicable Pricing
Supplement) commencing on the second day on which dealings in deposits in United
States dollars are transacted in the London interbank market (a "London Banking
Day") immediately following such Interest Determination Date; provided, however,
that if fewer

                                       8
<PAGE>
 
than two such quotations appear, the Calculation Agent shall request the
principal London office of four major banks in the London interbank market
selected by the Calculation Agent to provide the Calculation Agent with a
quotation of their offered rates at approximately 11:00 A.M., London time, on
such Interest Determination Date for deposits (in United States dollars for the
period of the applicable Index Maturity and in a principal amount equal to an
amount that is representative for a single transaction in such market at such
time) commencing on the second London Banking Day immediately following such
Interest Determination Date. If at least two such quotations are provided, LIBOR
for such Interest Determination Date will equal the arithmetic mean of such
quotations. If fewer than two quotations are provided, LIBOR for such Interest
Determination Date will equal the arithmetic mean of the rates quoted by three
major banks in The City of New York, as selected by the Calculation Agent, at
approximately 11:00 A.M., New York City time, on such Interest Determination
Date for loans to leading European banks (in United States dollars for the
period of the applicable Index Maturity and in a principal amount equal to an
amount that is representative for a single transaction in such market at such
time) commencing on the second London Banking Day following such Interest
Determination Date; provided, however, that if the banks selected as aforesaid
by the Calculation Agent are not quoting as mentioned in this sentence, LIBOR
for such Interest Determination Date will be LIBOR in effect on such Interest
Determination Date.

  The Interest Determination Date pertaining to an Interest Reset Date on a
LIBOR Note will be the second London Banking Day next preceding such Interest
Reset Date.


TREASURY INDEX RATE NOTES

  Treasury Index Rate Notes will bear interest at the interest rates (calculated
with reference to the Treasury Index Rate and the Spread or Spread Multiplier,
if any) specified in the applicable Pricing Supplement.

  Unless otherwise indicated in the Pricing Supplement, "Treasury Index Rate"
means, with respect to any Interest Determination Date relating to a Treasury
Index Rate Note, the per annum discount rate for direct obligations of the
United States with a maturity of thirteen weeks ("91-day Treasury bills"),
expressed as a bond equivalent on the basis of a year of 365 or 366 days, at the
91-day Treasury bill auction occurring on such Interest Determination Date as
published by the Board of Governors of the Federal Reserve System in
"Statistical Release H.15(519), Selected Interest Rates", or any successor
publication, under the heading "Treasury bills--auction average (investment)"
or (if not so published by 9:00 A.M. New York City time on the Calculation Date)
as reported by the United States Department of the Treasury. Such Treasury bills
are usually sold at auction on Monday of each week unless that day is a legal
holiday in which case the auction is usually held on the following Tuesday,
except that such auction may be held on the preceding Friday.

  The day of each such auction of 91-day Treasury bills, unless otherwise
specified in the Pricing Supplement, will be an Interest Determination Date
(provided that the results of such auction are so published or reported), and
each Business Day following such an Interest Determination Date will be a
Treasury Index Rate Note Interest Reset Date. The rate of interest applicable to
Treasury Index Rate Notes will therefore not be reset during any period in which
such auctions are not held or the results of such auctions are not so published
or reported.


ZERO COUPON NOTES

  Notes which do not bear interest ("Zero Coupon Notes") were initially offered
at a substantial discount from their principal amount at maturity. There will be
no periodic payments of interest. The calculation of the accrual of Original
Issue Discount (as defined below), in the period during which a Zero Coupon Note
remains outstanding, will be on a semiannual bond equivalent basis using a year
composed of twelve 30-day months. Upon maturity, Original Issue Discount will
cease to accrue on a Zero Coupon Note.

  Limitation of Claims in Bankruptcy:   If a bankruptcy proceeding is commenced
in respect of the Company, the claim of the Holder of a Zero Coupon Note with
respect to the principal amount thereof may, under Section 502(b)(2) of Title 11
of the United States Code, be limited to the issue price of the Zero Coupon Note
plus that portion of the Original Issue Discount that is amortized from the date
of issue to the commencement of the proceeding.

                                  OTHER TERMS

GENERAL

  The Notes are a series of Securities issued under an Indenture (the "Senior
Indenture"), (all such series being herein referred to as "Senior Debt
Securities") dated as of April 1, 1983, as amended and restated, between the
Company and The Chase Manhattan Bank, formerly known as Chemical Bank (successor
to Manufacturers Hanover Trust Company), as trustee (the "Trustee"). A copy of
the Senior Indenture is filed as an exhibit to the registration statements
relating to the Securities. The following summaries of certain provisions of the
Senior Indenture do not purport to be complete and are subject to, and qualified
in their entirety by reference to, all provisions of the Senior Indenture,
including the definition therein of certain terms.

  The Senior Indenture provides that series of Senior Debt Securities may from
time to time be issued thereunder, without limitation as to aggregate principal
amount, in one or more series and upon such terms as the Company may establish
pursuant to the provisions thereof.

  The Senior Indenture provides that the Senior Indenture and the Securities
will be governed by and construed in accordance with the laws of the State of
New York.

  The Senior Indenture provides that the Company may issue Senior Debt
Securities with terms different from those of Senior Debt Securities previously
issued, and "reopen" a previously issued series of Senior Debt Securities and
issue additional Senior Debt Securities of such series.

  The Senior Debt Securities are unsecured and rank pari passu with all other
unsecured and unsubordinated indebtedness of the Company. However, since the
Company is a holding company, the right of the Company, and hence the right of
creditors of the Company (including the Holders of Senior Debt Securities), to
participate in any distribution of the assets of any subsidiary upon its
liquidation or reorganization or otherwise is necessarily subject to the prior
claims of creditors of the subsidiary, except to the extent that claims of the
Company itself as a creditor of the subsidiary may be recognized. In addition,
dividends, loans and advances from certain subsidiaries, including MLPF&S, to
the Company are restricted by net capital requirements under the Securities
Exchange Act of 1934, as amended, and under rules of certain exchanges and other
regulatory bodies.


LIMITATIONS UPON LIENS

  The Senior Indenture provides that the Company may not, and may not permit any
Subsidiary to, create, assume, incur or permit to exist any indebtedness for
borrowed money secured by a pledge, lien or other encumbrance (except for
certain liens specifically permitted by the Senior Indenture) on the Voting
Stock owned directly or indirectly by the Company of any Subsidiary (other than
a Subsidiary which, at the time of the incurrence of such secured indebtedness,
has a net worth of less than $3,000,000) without making effective provision
whereby the Outstanding Senior Debt Securities will be secured equally and
ratably with such secured indebtedness.


LIMITATION ON DISPOSITION OF VOTING STOCK OF, AND MERGER AND SALE OF ASSETS BY,
MLPF&S

  The Senior Indenture provides that the Company may not sell, transfer or
otherwise dispose of any Voting Stock of MLPF&S or permit MLPF&S to issue, sell
or otherwise dispose of any of its Voting Stock, unless, after giving effect to
any such transaction, MLPF&S remains a Controlled Subsidiary (defined in the
Senior Indenture to mean a corporation more than 80% of the outstanding shares
of Voting Stock of which owned directly or indirectly by the Company). In
addition, the Company may not permit MLPF&S to (i) merge or consolidate, unless
the surviving company is a Controlled Subsidiary or (ii) convey or transfer its
properties and assets substantially as an entirety, except to one or more
Controlled Subsidiaries.


MERGER AND CONSOLIDATION

  The Senior Indenture provides that the Company may consolidate or merge with
or into any other corporation, and the Company may sell, lease or convey all or
substantially all of its assets to any corporation, provided that (i) the
corporation

                                       10
<PAGE>
 
(if other than the Company) formed by or resulting from any such consolidation
or merger or which shall have received such assets shall be a corporation
organized and existing under the laws of the United States of America or a state
thereof and shall assume payment of the principal of (and premium, if any) and
interest on the Senior Debt Securities and the performance and observance of all
of the covenants and conditions of the Senior Indenture to be performed or
observed by the Company, and (ii) the Company or such successor corporation, as
the case may be, shall not immediately thereafter be in default under the Senior
Indenture.


MODIFICATION AND WAIVER

  Modification and amendment of the Senior Indenture may be effected by the
Company and the Trustee with the consent of the Holders of at least 66 2/3% in
principal amount of the outstanding Senior Debt Securities of each series issued
pursuant to such indenture and affected thereby, provided that no such
modification or amendment may, without the consent of the Holder of each
Outstanding Senior Debt Security affected thereby, (a) change the Stated
Maturity of the principal of, or any installment of interest or Additional
Amounts payable on, any Senior Debt Security or any premium payable on the
redemption thereof, or change the Redemption Price; (b) reduce the principal
amount of, or the interest or Additional Amounts payable on, any Senior Debt
Security or reduce the amount of principal which could be declared due and
payable prior to the Stated Maturity; (c) change place or currency of any
payment of principal or any premium, interest or Additional Amounts payable on
any Senior Debt Security; (d) impair the right to institute suit for the
enforcement of any payment on or with respect to any Senior Debt Security; (e)
reduce the percentage in principal amount of the Outstanding Senior Debt
Securities of any series, the consent of whose Holders is required to modify or
amend the Indenture; or (f) modify the foregoing requirements or reduce the
percentage of Outstanding Senior Debt Securities necessary to waive any past
default to less than a majority. No modification or amendment of any
subordinated indenture or any subsequent indenture for subordinated debt
securities may adversely affect the rights of any holder of Senior Indebtedness
without the consent of such Holder. Except with respect to certain fundamental
provisions, the Holders of at least a majority in principal amount of
Outstanding Senior Debt Securities of any series may, with respect to such
series, waive past defaults under the Senior Indenture and waive compliance by
the Company with certain provisions thereof.


EVENTS OF DEFAULT

  Under the Senior Indenture, the following will be Events of Defaults with
respect to Senior Debt Securities of any series: (a) default in the payment of
any interest or Additional Amounts payable on any Senior Debt Security of that
series when due, continued for 30 days; (b) default in the payment of any
principal or premium, if any, on any Senior Debt Security of that series when
due; (c) default in the deposit of any sinking fund payment, when due, in
respect of any Senior Debt Security of that series; (d) default in the
performance of any other covenant of the Company contained in the Indenture for
the benefit of such series or in the Senior Debt Securities of such series,
continued for 60 days after written notice as provided in the Senior Indenture;
(e) certain events in bankruptcy, insolvency or reorganization; and (f) any
other Event of Default provided with respect to Senior Debt Securities of that
series. The Trustee or the Holders of 25% in principal amount of the Outstanding
Senior Debt Securities of that series may declare the principal amount (or such
lesser amount as may be provided for in the Senior Debt Securities of that
series) of all Outstanding Senior Debt Securities of that series and the
interest due thereon and Additional Amounts payable in respect thereof, if any
to be due and payable immediately if an Event of Default with respect to Senior
Debt Securities of such series shall occur and be continuing at the time of such
declaration. At any time after a declaration of acceleration has been made with
respect to Senior Debt Securities of any series but before a judgment or decree
for payment of money due has been obtained by the Trustee, the Holders of a
majority in principal amount of the Outstanding Senior Debt Securities of that
series may rescind any declaration of acceleration and its consequences, if all
payments due (other than those due as a result of acceleration) have been made
and all Events of Default have been remedied or waived. Any Event of Default
with respect to Senior Debt Securities of any series may be waived by the
Holders of a majority in principal amount of all Outstanding Senior Debt
Securities of that series, except in a case of failure to pay principal or
premium, if any, or interest or Additional Amounts payable on any Senior Debt
Security of that series for which payment had not been subsequently made or in
respect of a covenant or provision which cannot be modified or amended without
the consent of the Holder of each Outstanding Senior Debt Security of such
series affected.

  The Holders of a majority in principal amount of the Outstanding Senior Debt
Securities of a series may 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 Senior Debt Securities of such
series, provided that such direction shall not be in

                                       11
<PAGE>
 
conflict with any rule of law or the Senior Indenture. Before proceeding to
exercise any right or power under the Senior Indenture at the direction of such
Holders, the Trustee shall be entitled to receive from such Holders reasonable
security or indemnity against the costs, expenses and liabilities which might be
incurred by it in complying with any such direction.

  The Company is required to furnish to the Trustee annually a statement as to
the fulfillment by the Company of all of its obligations under the Senior
Indenture.

  DESCRIPTION OF SENIOR DEBT SECURITIES

  The Senior Debt Securities have been and are to be issued under an Indenture
(the "Senior Indenture"), dated as of April 1, 1983, as amended and restated,
between the Company and The Chase Manhattan Bank, formerly known as Chemical
Bank (successor by merger to Manufacturers Hanover Trust Company), as trustee
(the "Trustee").  A copy of the Senior Indenture is filed as an exhibit to the
registration statements relating to the Securities.  The following summaries of
certain provisions of the Senior Indenture do not purport to be complete and are
subject to, and are qualified in their entirety by reference to, all provisions
of the Senior Indenture, including the definition therein of certain terms.

  The Senior Indenture provides that series of Senior Debt Securities may from
time to time be issued thereunder, without limitation as to aggregate principal
amount, in one or more series and upon such terms as the Company may establish
pursuant to the provisions thereof.

  The Senior Indenture provides that the Senior Indenture and the Securities are
governed by and construed in accordance with the laws of the State of New York.
Under present New York law the maximum rate of interest is 25% per annum on a
simple interest basis.  This limit may not apply to Securities in which
$2,500,000 or more has been invested.  While the Company believes that New York
law would be given effect by a state or Federal court sitting outside of New
York, state laws frequently regulate the amount of interest that may be charged
to and paid by a borrower (including, in some cases, corporate borrowers).  The
Company has covenanted for the benefit of the Holders of Securities, to the
extent permitted by law, not to claim voluntarily the benefits of any laws
concerning usurious rates of interest against a Holder of Securities.

  The Outstanding Senior Debt Securities are issuable only in fully registered
form without coupons, in denominations set forth below under each description of
Outstanding Senior Debt Securities.  No service charge will be made for any
registration of transfer or exchange of such Senior Debt Securities, but the
Company may require payment of a sum sufficient to cover any tax or other
governmental charges that may be imposed in connection therewith.  The
description below indicates that certain of the Outstanding Senior Debt
Securities have been issued in global form (see "Book-Entry Securities").

  The Senior Indenture provides that the Company may issue Senior Debt
Securities with terms different from those of Senior Debt Securities previously
issued, and "reopen" a previously issued series of Senior Debt Securities and
issue additional Senior Debt Securities of such series.

  The Senior Debt Securities are unsecured and rank pari passu with all other
unsecured and unsubordinated indebtedness of the Company.  However, since the
Company is a holding company, the right of the Company, and hence the right of
creditors of the Company (including the Holders of the Senior Debt Securities),
to participate in any distribution of the assets of any subsidiary upon its
liquidation or reorganization or otherwise is necessarily subject to the prior
claims of creditors of the subsidiary, except to the extent that claims of the
Company itself as a creditor of the subsidiary may be recognized.  In addition,
dividends, loans and advances from certain subsidiaries, including MLPF&S, to
the Company are restricted by net capital requirements under the Exchange Act
and under rules of certain exchanges and other regulatory bodies.

  Any principal, premium and interest is and will be payable, the transfer of
the Senior Debt Securities is and will be registrable, and Senior Debt
Securities are and will be exchangeable, at the office of the Trustee in New
York City designated for such purpose, provided that (except as otherwise set
forth below with respect to any series of Senior Debt Securities) payment of
interest may be made at the option of the Company by check mailed to the address
of the person entitled thereto as shown on the Security Register.

  Unless otherwise specified with respect to a particular series of Senior Debt
Securities, the Senior Debt Securities are not subject to any sinking fund and
are not redeemable prior to maturity.

  Unless otherwise specified, terms defined under a caption for a specific
series of Senior Debt Securities shall have such meanings only as to the Senior
Debt Securities described therein.

BOOK-ENTRY SECURITIES

  Certain of the Outstanding Senior Debt Securities have been issued in global
form (such Outstanding Senior Debt Securities are hereinafter referred to as
"Book-Entry Securities").  Such Book-Entry Securities are represented

                                       4
<PAGE>
 
by one or more fully registered global securities (the "Global Notes").  Each
such Global Note has been deposited with, or on behalf of, The Depository Trust
Company ("DTC"), as Depository, registered in the name of DTC or a nominee
thereof.  Unless and until it is exchanged in whole or in part for Senior Debt
Securities in definitive form, no Global Note may be transferred except as a
whole by the Depository to a nominee of such Depository or by a nominee of such
Depository to such Depository or another nominee of such Depository or by such
Depository or any such nominee to a successor of such Depository or a nominee of
such successor.

  DTC has advised the Company as follows:  DTC is a limited-purpose trust
company organized under the Banking Law of the State of New York, a member of
the Federal Reserve System, a "clearing corporation" within the meaning of the
New York Uniform Commercial Code, and a "clearing agency" registered pursuant to
the provisions of Section 17A of the Exchange Act.  DTC was created to hold
securities of its participants ("Participants") and to facilitate the clearance
and settlement of securities transactions among its Participants in such
securities through electronic book-entry changes in accounts of the
Participants, thereby eliminating the need for physical movement of securities
certificates.  DTC's Participants include securities brokers and dealers, banks,
trust companies, clearing corporations, and certain other organizations,
including the Underwriters.

  DTC is owned by a number of Participants and by the New York Stock Exchange,
Inc. and the National Association of Securities Dealers, Inc.  Access to DTC's
book-entry system is also available to others, such as banks, brokers, dealers
and trust companies that clear through or maintain a custodial relationship with
a Participant, either directly or indirectly ("Indirect Participants").

  Purchases of Book-Entry Securities must be made by or through Participants,
which will receive a credit on the records of DTC.  The ownership interest of
each actual purchaser of each Book-Entry Security (the "Beneficial Owner") is in
turn to be recorded on the Participants' or Indirect Participants' records.
Beneficial Owners will not receive written confirmation from DTC of their
purchase, but Beneficial Owners are expected to receive written confirmations
providing details of the transaction, as well as periodic statements of their
holdings, from the Participant or Indirect Participant through which the
Beneficial Owner entered into the transaction.  Ownership of beneficial
interests in Global Notes will be shown on, and the transfer of such ownership
interests will be effected only through, records maintained by DTC (with respect
to interests of Participants) and on the records of Participants (with respect
to interests of persons held through Participants).  The laws of some states may
require that certain purchasers of securities take physical delivery of such
securities in definitive form.  Such limits and such laws may impair the ability
to own, transfer or pledge beneficial interests in Global Notes.

  So long as DTC, or its nominee, is the registered owner of a Global Note, DTC
or its nominee, as the case may be, will be considered the sole owner or Holder
of the Book-Entry Securities represented by such Global Note for all purposes
under the Indenture.  Except as provided below, Beneficial Owners in a Global
Note will not be entitled to have the Book-Entry Securities represented by such
Global Note registered in their names, will not receive or be entitled to
receive physical delivery of the Book-Entry Securities in definitive registered
form and will not be considered the owners or Holders thereof under the
Indenture.  Accordingly, each Person owning a beneficial interest in a Global
Note must rely on the procedures of DTC and, if such Person is not a
Participant, on the procedures of the Participant through which such Person owns
its interest, to exercise any rights of a Holder under the Indenture.  The
Company understands that under existing industry practices, in the event that
the Company requests any action of Holders or that an owner of a beneficial
interest in such a Global Note desires to give or take any action which a Holder
is entitled to give or take under the Indenture, DTC would authorize the
Participants holding the relevant beneficial interests to give or take such
action, and such Participants would authorize Beneficial Owners owning through
such participants to give or take such action or would otherwise act upon the
instructions of Beneficial Owners.  Conveyance of notices and other
communications by DTC to Participants, by Participants to Indirect Participants,
and by Participants and Indirect Participants to Beneficial Owners will be
governed by arrangements among them, subject to any statutory or regulatory
requirements as may be in effect from time to time.

  Payment of principal of, and interest on, Book-Entry Securities registered in
the name of DTC or its nominee will be made to DTC or its nominee, as the case
may be, as the Holder of the Global Note or Global Notes representing such Book-
Entry Securities.  None of the Company, the Trustee or any other agent of the
Company or agent of the Trustee will have any responsibility or liability for
any aspect of the records relating to or payments made on account of beneficial
ownership interests or for supervising or reviewing any records relating to such
beneficial ownership interests.  The Company expects that DTC, upon receipt of
any payment of principal or interest in respect of a Global Note, will credit
the accounts of the Participants with payment in amounts proportionate to their
respective holdings in principal amount of beneficial interest in such Global
Note as shown on the records of

                                       5
<PAGE>
 
DTC.  The Company also expects that payments by Participants to Beneficial
Owners will be governed by standing customer instructions and customary
practices, as is now the case with securities held for the accounts of customers
in bearer form or registered in "street name", and will be the responsibility of
such Participants.

  If (x) any Depository is at any time unwilling or unable to continue as
Depository and a successor depository is not appointed by the Company within 60
days, or (y) the Company executes and delivers to the Trustee a Company Order to
the effect that the Global Notes shall be exchangeable, or (z) an Event of
Default has occurred and is continuing with respect to the Book-Entry
Securities, the Global Note or Global Notes will be exchangeable for Senior Debt
Securities in definitive form of like tenor and of an equal aggregate principal
amount, in denominations of $1,000 and integral multiples thereof.  Such
definitive Senior Debt Securities shall be registered in such name or names as
the Depository shall instruct the Trustee.  It is expected that such
instructions may be based upon directions received by the Depository from
Participants with respect to ownership of beneficial interests in Global Notes.

  All payments of principal and interest on the Book-Entry Securities will be
made by the Company in immediately available funds so long as such securities
are maintained in book-entry form.

                                  OTHER TERMS

LIMITATIONS UPON LIENS

     The Company may not, and may not permit any Subsidiary to, create, assume,
incur or permit to exist any indebtedness for borrowed money secured by a
pledge, lien or other encumbrance (except for certain liens specifically
permitted by the Senior Indenture) on the Voting Stock owned directly or
indirectly by the Company of any Subsidiary (other than a Subsidiary which, at
the time of the incurrence of such secured indebtedness, has a net worth of less
than $3,000,000) without making effective provision whereby the Outstanding
Senior Debt Securities will be secured equally and ratably with such secured
indebtedness.

LIMITATION ON DISPOSITION OF VOTING STOCK OF, AND MERGER AND SALE OF ASSETS BY,
MLPF&S

     The Indenture provides that the Company may not sell, transfer or otherwise
dispose of any Voting Stock of MLPF&S or permit MLPF&S to issue, sell or
otherwise dispose of any of its Voting Stock, unless, after giving effect to any
such transaction, MLPF&S remains a Controlled Subsidiary (defined in the Senior
Indenture to mean a corporation more than 80% of the outstanding shares of
Voting Stock of which are owned directly or indirectly by the Company).  In
addition, the Company may not permit MLPF&S to (i) merge or consolidate, unless
the surviving company is a Controlled Subsidiary or (ii) convey or transfer its
properties and assets substantially as an entirety, except to one or more
Controlled Subsidiaries.

MERGER AND CONSOLIDATION

     The Indenture provides that the Company may consolidate or merge with or
into any other corporation, and the Company may sell, lease or convey all or
substantially all of its assets to any corporation, provided that (i) the
corporation (if other than the Company) formed by or resulting from any such
consolidation or merger or which shall have received such assets shall be a
corporation organized and existing under the laws of the United States of
America or a state thereof and shall assume payment of the principal of (and
premium, if any) and interest on the Senior Debt Securities and the performance
and observance of all of the covenants and conditions of the Senior Indenture to
be performed or observed by the Company, and (ii) the Company or such successor
corporation, as the case may be, shall not immediately thereafter be in default
under the Senior Indenture.

MODIFICATION AND WAIVER

     Modification and amendment of the Indenture may be effected by the Company
and the Trustee with the consent of the Holders of 66 2/3% in principal amount
of the Outstanding Senior Debt Securities of each series issued pursuant to such
indenture and affected thereby, provided that no such modification or amendment
may, without the consent of the Holder of each Outstanding Senior Debt Security
affected thereby, (a) change the Stated Maturity of the principal of, or any
installment of interest or Additional Amounts payable on, any Senior Debt
Security or any premium payable on the redemption thereof, or change the
Redemption Price; (b) reduce the principal amount of, or the interest or
Additional Amounts payable on, any Senior Debt Security or reduce the amount of
principal which could be declared due and payable prior to the Stated Maturity;
(c) change place or currency of any payment of principal or any premium,
interest or Additional Amounts payable on any Senior Debt Security; (d) impair
the right to institute suit for the enforcement of any payment on or with
respect to any Senior Debt Security; (e) reduce the percentage in principal
amount of the Outstanding Senior Debt Securities of any series, the consent of
whose Holders is required to modify or amend the Indenture; or (f) modify the
foregoing requirements or reduce the percentage of Outstanding Senior Debt
Securities necessary to waive any past default to less than a majority.  No
modification or amendment of the Subordinated Indenture or any Subsequent
Indenture for Subordinated Debt Securities may adversely affect the rights of
any holder of Senior Indebtedness without the consent of such Holder.  Except
with respect to certain fundamental provisions, the Holders of at least a
majority in principal amount of Outstanding Senior Debt Securities of any series
may, with respect to such series, waive past defaults under the Indenture and
waive compliance by the Company with certain provisions thereof.

EVENTS OF DEFAULT

     Under the Senior Indenture, the following will be Events of Default with
respect to Senior Debt Securities of any series: (a) default in the payment of
any interest or Additional Amounts payable on any Senior Debt Security of that
series when due, continued for 30 days; (b) default in the payment of any
principal or premium, if any, on any Senior Debt Security of that series when
due; (c) default in the deposit of any sinking fund payment, when due,

                                       9

in respect of any Senior Debt Security of that series; (d) default in the
performance of any other covenant of the Company contained in the Indenture for
the benefit of such series or in the Senior Debt Securities of such series,
continued for 60 days after written notice as provided in the Senior Indenture;
(e) certain events in bankruptcy, insolvency or reorganization; and (f) any
other Event of Default provided with respect to Senior Debt Securities of that
series.  The Trustee or the Holders of 25% in principal amount of the
Outstanding Senior Debt Securities of that series may declare the principal
amount (or such lesser amount as may be provided for in the Senior Debt
Securities of that series) of all Outstanding Senior Debt Securities of that
series and the interest due thereon and Additional Amounts payable in respect
thereof, if any to be due and payable immediately if an Event of Default with
respect to Senior Debt Securities of such series shall occur and be continuing
at the time of such declaration.  At any time after a declaration of
acceleration has been made with respect to Senior Debt Securities of any series
but before a judgment or decree for payment of money due has been obtained by
the Trustee, the Holders of a majority in principal amount of the Outstanding
Senior Debt Securities of that series may rescind any declaration of
acceleration and its consequences, if all payments due (other than those due as
a result of acceleration) have been made and all Events of Default have been
remedied or waived.  Any Event of Default with respect to Senior Debt Securities
of any series may be waived by the Holders of a majority in principal amount of
all Outstanding Senior Debt Securities of that series, except in a case of
failure to pay principal or premium, if any, or interest or Additional Amounts
payable on any Senior Debt Security of that series for which payment had not
been subsequently made or in respect of a covenant or provision which cannot be
modified or amended without the consent of the Holder of each Outstanding Senior
Debt Security of such series affected.

     The Holders of a majority in principal amount of the Outstanding Senior
Debt Securities of a series may 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 Senior Debt Securities of such
series, provided that such direction shall not be in conflict with any rule of
law or the Senior Indenture.  Before proceeding to exercise any right or power
under the Senior Indenture at the direction of such Holders, the Trustee shall
be entitled to receive from such Holders reasonable security or indemnity
against the costs, expenses and liabilities which might be incurred by it in
complying with any such direction.

     The Company is required to furnish to the Trustee annually a statement as
to the fulfillment by the Company of all of its obligations under the Senior
Indenture.

                           MERRILL LYNCH & CO., INC.
        S&P 500 MARKET INDEX TARGET-TERM SECURITIES/(SM)/ DUE AUGUST 29, 1997
                                  ("MITTS(R)")

  On July 30, 1992, Merrill Lynch & Co., Inc. (the "Company") issued $77,500,000
aggregate principal amount (7,750,000 Units) of the Securities.  Each $10
principal amount of S&P 500 Market Index Target-Term Securities due August 29,
1997 (the "Securities" or "MITTS") will be deemed a "Unit" for purposes of
trading and transfer at the Securities Depository described below.  Units will
be transferable by the Securities Depository, as more fully described below, in
denominations of whole Units.

  The Securities bear no periodic payments of interest and will mature on August
29, 1997. At maturity, a Holder of a Security will be entitled to receive, with
respect to each Security, the principal amount thereof, plus a contingent
interest payment (the "Supplemental Redemption Amount"), if any, if the Final
Value (as defined herein) of the S&P 500 Composite Stock Price Index (the "S&P
500 Index") exceeds 412.08 (the "Initial Value"). If the Final Value does not
exceed the Initial Value, a Holder of a Security will be repaid the principal
amount of the Security, but the Holder will not receive any Supplemental
Redemption Amount. The Securities were issued as a series of Senior Debt
Securities under the Senior Indenture described herein. The Securities are not
redeemable prior to maturity.

  The Supplemental Redemption Amount, if any, payable with respect to a Security
at maturity will equal the product of (A) the principal amount of the applicable
Security, and (B) the quotient of the Final Value less the Initial Value,
divided by the Initial Value, and (C) 115%. The calculation of the Final Value,
as more fully described herein, will be based upon certain values of the S&P 500
Index during the ten Business Days prior to the maturity date of the Securities.

  For information as to the calculation of the Supplemental Redemption Amount,
if any, which will be paid at maturity, the calculation and the composition of
the S&P 500 Index, see "Description of Securities" and "The Standard & Poor's
500 Index" in this Prospectus.  FOR OTHER INFORMATION THAT SHOULD BE CONSIDERED
BY PROSPECTIVE INVESTORS, SEE "RISK FACTORS" BEGINNING ON PAGE 4 OF THIS
PROSPECTUS.

  Ownership of the Securities will be maintained in book-entry form by or
through the Securities Depository. Beneficial owners of the Securities will not
have the right to receive physical certificates evidencing their ownership
except under the limited circumstances described herein.

  The Securities have been listed on the New York Stock Exchange under the
symbol "MIT".

  While at maturity a beneficial owner of a Security may receive an amount in
excess of the principal amount of such Security if the Final Value exceeds the
Initial Value, there will be no payment of interest, periodic or otherwise,
prior to maturity.  (See "Description of the Securities--Payment at Maturity" in
this Prospectus.)

  The Securities are not subject to redemption by the Company or at the option
of any Holder prior to maturity. Upon the occurrence of an Event of Default with
respect to the Securities, Holders of the Securities may accelerate the maturity
of the Securities, as described under "Description of Securities--Events of
Default and Acceleration".

  The Securities were issued in denominations of whole Units.

  At maturity, a Holder of a Security will be entitled to receive the principal
amount thereof ($10 per Unit) plus a Supplemental Redemption Amount, if any, all
as provided below. If the Final Value of the S&P 500 Index does not exceed the
Initial Value, a Holder of a Security will be repaid the principal amount of the
Security at maturity, but will not be entitled to receive any contingent
interest (i.e., Supplemental Redemption Amount).

"earnings" consists of earnings from continuing operations before income taxes
and fixed charges.  "Fixed charges" consists of interest costs,

<PAGE>
 
amortization of debt expense, preferred stock dividend requirements of majority-
owned subsidiaries, and that portion of rentals estimated to be representative
of the interest factor.


                                  RISK FACTORS
PAYMENT AT MATURITY

  If the Final Value is equal to or less than the Initial Value, the Holders of
the Securities will be entitled to receive $10 in respect of each $10 principal
amount of Securities, and no Supplemental Redemption Amount. This will be true
even though the value of the S&P 500 Index as of some interim period or periods
prior to the maturity date of the Securities may have exceeded the Initial Value
because the Supplemental Redemption Amount on the Securities is calculated on
the basis of the Final Value only.

  The $10 minimum to be received by Holders at maturity in respect of each $10
principal amount of a Security does not reflect any opportunity cost implied by
inflation and other factors relating to the time value of money.

  The S&P 500 Index does not reflect the payment of dividends on the stocks
underlying it and therefore the yield based on the S&P 500 Index to the maturity
of the Securities will not produce the same yield as if such underlying stocks
were purchased and held for a similar period.

TRADING

  The Securities have been listed on the New York Stock Exchange under the
symbol "MIT".

  The trading value of the Securities is expected to depend primarily on the
extent of the appreciation, if any, of the S&P 500 Index over the Initial Value.
If, however, Securities are sold prior to the maturity date at a time when the
S&P 500 Index exceeds the Initial Value, the sale price may be at a discount
from the amount expected to be payable to the Holder if such excess of the S&P
500 Index over the Initial Value were to prevail until maturity of the
Securities because of the possible fluctuation of the S&P 500 Index between the
time of such sale and the maturity date. (See "The Standard & Poor's 500 Index")
Furthermore, the price at which a Holder will be able to sell Securities prior
to maturity may be at a discount, which could be substantial, from the principal
amount thereof, if, at such time, the S&P 500 Index is below, equal to or not
sufficiently above the Initial Value. A discount could also result from rising
interest rates.

  The trading values of the Securities may be affected by a number of
interrelated factors, including the creditworthiness of the Company and those
factors listed below. The relationship among these factors is complex, including
how these factors affect the relative value of the principal amount of the
Securities to be repaid at maturity and the value of the Supplemental Redemption
Amount. Accordingly, investors should be aware that factors other than the level
of the S&P 500 Index are likely to affect their trading value. The expected
theoretical effect on the trading value of the Securities of each of the factors
listed below, assuming in each case that all other factors are held constant, is
as follows:

  Interest Rates. In general, if U.S. interest rates increase, the value of the
  Securities is expected to decrease. If U.S. interest rates decrease, the value
  of the Securities is expected to increase. Interest rates may also affect the
  U.S. economy, and, in turn, the value of the S&P 500 Index. Rising interest
  rates may lower the value of the S&P 500 Index and, thus, the Securities.
  Falling interest rates may increase the value of the S&P 500 Index and, thus,
  may increase the value of the Securities.

  Volatility of the S&P 500 Index. If the volatility of the S&P 500 Index
  increases, the trading value of the Securities is expected to increase. If the
  volatility of the S&P 500 Index decreases, the trading value of the Securities
  is expected to decrease.

                                       4
<PAGE>
 
  Time Remaining to Maturity. The Securities may trade at a value above that
  which may be inferred from the level of interest rates and the S&P 500 Index.
  This difference will reflect a "time premium" due to expectations concerning
  the value of the S&P 500 Index during the period prior to maturity of the
  Securities. As the time remaining to maturity of the Securities decreases,
  however, this time premium is expected to decrease, thus decreasing the
  trading value of the Securities.

  Dividend Rates in the United States. If dividend rates on the stocks
  comprising the S&P 500 Index increase, the value of the Securities is expected
  to decrease. Conversely, if dividend rates on the stocks comprising the S&P
  500 Index decrease, the value of the Securities is expected to increase.
  However, in general, rising U.S. corporate dividend rates may increase the S&P
  500 Index and, in turn, increase the value of the Securities. Conversely,
  falling U.S. dividend rates may decrease the S&P 500 Index and, in turn,
  decrease the value of the Securities.

OTHER CONSIDERATIONS

  It is suggested that prospective investors who consider purchasing the
Securities should reach an investment decision only after carefully considering
the suitability of the Securities in the light of their particular
circumstances.

  Investors should also consider the tax consequences of investing in the
Securities and should consult their tax advisors.


                           DESCRIPTION OF SECURITIES

GENERAL

  The Securities were issued as a series of Senior Debt Securities under the
Senior Indenture, dated as of April 1, 1983, as amended and restated, which is
more fully described in this Prospectus.  The Securities will mature on August
29, 1997.

  While at maturity a beneficial owner of a Security may receive an amount in
excess of the principal amount of such Security if the Final Value exceeds the
Initial Value, there will be no payment of interest, periodic or otherwise,
prior to maturity.  (See "Payment at Maturity", below.)

  The Securities are not subject to redemption by the Company or at the option
of any Holder prior to maturity. Upon the occurrence of an Event of Default with
respect to the Securities, Holders of the Securities may accelerate the maturity
of the Securities, as described under "Description of Securities--Events of
Default and Acceleration" and "Other Terms--Events of Default" in this
Prospectus.

  The Securities were issued in denominations of whole Units.

PAYMENT AT MATURITY

  At maturity, a Holder of a Security will be entitled to receive the principal
amount thereof ($10 per Unit) plus a Supplemental Redemption Amount, if any, all
as provided below. If the Final Value of the S&P 500 Index does not exceed the
Initial Value, a Holder of a Security will be repaid the principal amount of the
Security at maturity, but will not be entitled to receive any contingent
interest (i.e., Supplemental Redemption Amount).

                                       5
<PAGE>
 
     At maturity, a Holder of a Security will be entitled to receive, with
respect to each such Security, (i) the principal amount thereof, and (ii) the
Supplemental Redemption Amount, if any, equal in amount to:

               Principal  X  (Final Value - Initial Value) X 115%
                              ---------------------------        
                                     Initial Value

provided, however, that the Supplemental Redemption Amount will not be less than
zero. The Initial Value of the S&P 500 Index is 412.08. If the Final Value does
not exceed the Initial Value, the Supplemental Redemption Amount will equal zero
and a Holder of a Security will receive only the principal amount thereof ($10
for each $10 price to public).

     The Final Value of the S&P 500 Index will be determined by State Street
Bank and Trust Company (the "Calculation Agent") and will equal the average
(mean) of the closing values of the S&P 500 Index as calculated by S&P on the
tenth Business Day (as defined below) prior to the maturity date (provided that
a Market Disruption Event, as defined below, shall not have occurred on such
day) and on each succeeding Business Day (provided that a Market Disruption
Event shall not have occurred on the applicable day) up to and including the
fourth Business Day prior to the maturity date (each, a "Calculation Day") until
the Calculation Agent has so determined such closing values for five Business
Days. If a Market Disruption Event occurs on one or more of the Business Days
during the period specified above, the Final Value will equal the average of the
values on Business Days on which a Market Disruption Event did not occur or, if
there is only one such Business Day, the value on such day. If Market Disruption
Events occur on all of such Business Days during such period, the Final Value
shall equal the closing value of the S&P 500 Index on the fourth Business Day
prior to the maturity date regardless of whether a Market Disruption Event shall
have occurred on such day. For purposes of determining the Final Value, a
"Business Day" is a day on which The New York Stock Exchange is open for
trading. All determinations made by the Calculation Agent shall be at the sole
discretion of the Calculation Agent and, in the absence of manifest error, shall
be conclusive for all purposes and binding on the Company and Holders of the
Securities.

     If S&P discontinues publication of the S&P 500 Index and S&P or another
entity publishes a successor or substitute index that the Calculation Agent
determines, in its sole discretion, to be comparable to the S&P 500 Index (any
such index being referred to hereinafter as a "Successor Index"), then, upon the
Calculation Agent's notification of such determination to the Trustee and the
Company, the Calculation Agent will substitute the Successor Index as calculated
by S&P or such other entity for the S&P 500 Index and calculate the Final Value
as described in the preceding paragraph. Upon any selection by the Calculation
Agent of a Successor Index, the Company shall cause notice thereof to be
published in The Wall Street Journal (or another newspaper of general
circulation) within three Business Days of such selection.

     If S&P discontinues publication of the S&P 500 Index and a Successor Index
is not selected by the Calculation Agent or is no longer published on any of the
Calculation Days, the value to be substituted for the S&P 500 Index for any such
Calculation Day used to calculate the Supplemental Redemption Amount, if any, at
maturity will be calculated as described below under "Discontinuance of the S&P
500 Index".

     If a Successor Index is selected or the Calculation Agent calculates a
value as a substitute for the S&P 500 Index as described below, such Successor
Index or value shall be substituted for the S&P 500 Index for all purposes,
including for purposes of determining whether a Market Disruption Event exists.

     If at any time the method of calculating the S&P 500 Index, or the value
thereof, is changed in a material respect, or if the S&P 500 Index is in any
other way modified so that such Index does not, in the opinion of the
Calculation Agent, fairly represent the value of the S&P 500 Index had such
changes or modifications not been made, then, from and after such time, the
Calculation Agent shall, at the close of business in New York, New York, on each
date that the closing value with respect to the Final Value is to be calculated,
make such adjustments as, in the good faith judgment of the Calculation Agent,
may be necessary in order to arrive at a calculation of a

                                       6
<PAGE>
 
value of a stock index comparable to the S&P 500 Index as if such changes or
modifications had not been made, and calculate such closing value with reference
to the S&P 500 Index, as adjusted. Accordingly, if the method of calculating the
S&P 500 Index is modified so that the value of such Index is a fraction or a
multiple of what it would have been if it had not been modified (e.g., due to a
split in the Index), then the Calculation Agent shall adjust such Index in order
to arrive at a value of the S&P 500 Index as if it had not been modified (e.g.,
as if such split had not occurred).

     "Market Disruption Event" means either of the following events, as
determined by the Calculation Agent:

          (i) the suspension or material limitation (limitations pursuant to New
     York Stock Exchange Rule 80A (or any applicable rule or regulation enacted
     or promulgated by the New York Stock Exchange, any other self-regulatory
     organization or the Commission of similar scope as determined by the
     Calculation Agent) on trading during significant market fluctuations shall
     be considered "material" for purposes of this definition), in each case,
     for more than two hours of trading in 100 or more of the securities
     included in the S&P 500 Index, or

          (ii) the suspension or material limitation, in each case, for more
     than two hours of trading (whether by reason of movements in price
     otherwise exceeding levels permitted by the relevant exchange or otherwise)
     in (A) futures contracts related to the S&P 500 Index which are traded on
     the Chicago Mercantile Exchange or (B) option contracts related to the S&P
     500 Index which are traded on the Chicago Board Options Exchange, Inc.

     For the purposes of this definition, a limitation on the hours in a trading
day and/or number of days of trading will not constitute a Market Disruption
Event if it results from an announced change in the regular business hours of
the relevant exchange.

     The following table illustrates, for a range of hypothetical Final Values,
the percentage change in the S&P 500 Index from the date of issuance of the
Securities offered hereby until maturity and the Supplemental Redemption Amount
at maturity for each $10 principal amount of Securities.

     The above figures are for purposes of illustration only. The actual
 Supplemental Redemption Amount received by investors will depend entirely on
 the actual Final Value determined by the Calculation Agent as provided herein.
 
    The Senior Indenture provides that the Senior Indenture and the Securities
will be governed by and construed in accordance with the laws of New York.
Under present New York law, the maximum rate of interest is 25% per annum on a
simple interest basis.  This limit may not apply to Securities in which
$2,500,000 or more has been invested.  While the Company believes that New York
law would be given effect by a state or Federal court sitting outside of New
York, state laws frequently regulate the amount of interest that may be charged
to and paid by a borrower (including, in some cases, corporate borrowers).  It
is suggested that prospective investors consult their personal advisors with
respect to the applicability of such laws.  The Company has covenanted for the
benefit of the Holders of the Securities, to the extent permitted by law, not to
claim voluntarily the benefits of any laws concerning usurious rates of interest
against a Holder of the Securities.

DISCONTINUANCE OF THE S&P 500 INDEX AND SUCCESSOR INDEX

    If S&P discontinues publication of the S&P 500 Index and a Successor Index
is available, then the amount payable at maturity or upon earlier acceleration
will be determined by reference to the Successor Index, as provided above.

    If the publication of the S&P 500 Index is discontinued and S&P or another
entity does not publish a Successor Index on any of the Calculation Days, the
value to be substituted for the S&P 500 Index for any such Calculation Day used
to calculate the Supplemental Redemption Amount, if any, at maturity will be the
value computed by the Calculation Agent for each such Calculation Day in
accordance with the following procedures:

                                       8
<PAGE>
 
        (1) identifying the component stocks of the S&P 500 Index or any
    Successor Index as of the last date on which either of such indices was
    calculated by S&P or another entity and published by S&P or such other
    entity (each such component stock is a "Last Component Stock");

        (2) for each Last Component Stock, calculating as of each such Business
    Day the product of the market price per share and the number of the then
    outstanding shares (such product referred to as the "Market Value" of such
    stock), by reference to (a) the closing market price per share of such Last
    Component Stock as quoted by the New York Stock Exchange or the American
    Stock Exchange or any other registered national securities exchange that is
    the primary market for such Last Component Stock, or if no such quotation is
    available, then the closing market price as quoted by any other registered
    national securities exchange or the National Association of Securities
    Dealers Automated Quotation National Market System ("NASDAQ"), or if no such
    price is quoted, then the market price from the best available source as
    determined by the Calculation Agent (collectively, the "Exchanges") and (b)
    the most recent publicly available statement of the number of outstanding
    shares of such Last Component Stock;

        (3) aggregating the Market Values obtained in clause (2) for all Last
    Component Stocks;

        (4) ascertaining the Base Value (as defined below under "The Standard &
    Poor's 500 Index--Computation of the Index") in effect as of the last day on
    which either the S&P 500 Index or any Successor Index was published by S&P
    or another entity, adjusted as described below;

        (5) dividing the aggregate Market Value of all Last Component Stocks by
    the Base Value (adjusted as aforesaid);

        (6) multiplying the resulting quotient (expressed in decimals) by ten.

    If any Last Component Stock is no longer publicly traded on any registered
national securities exchange or in the over-the-counter market, the last
available market price per share for such Last Component Stock as quoted by any
registered national securities exchange or in the over-the-counter market, and
the number of outstanding shares thereof at such time, will be used in computing
the last available Market Value of such Last Component Stock. Such Market Value
will be used in all computations of the S&P 500 Index thereafter.

    If a company that has issued a Last Component Stock and another company that
has issued a Last Component Stock are consolidated to form a new company, the
common stock of such new company will be considered a Last Component Stock and
the common stocks of the constituent companies will no longer be considered Last
Component Stocks. If any company that has issued a Last Component Stock merges
with, or acquires, a company that has not issued a Last Component Stock, the
common stock of the surviving corporation will, upon the effectiveness of such
merger or acquisition, be considered a Last Component Stock. In each such case,
the Base Value will be adjusted so that the Base Value immediately after such
consolidation, merger or acquisition will equal (a) the Base Value immediately
prior to such event, multiplied by (b) the quotient of the aggregate Market
Value of all Last Component Stocks immediately after such event, divided by the
aggregate Market Value for all Last Component Stocks immediately prior to such
event.

    If a company that has issued a Last Component Stock issues a stock dividend,
declares a stock split or issues new shares pursuant to the acquisition of
another company, then, in each case, the Base Value will be adjusted (in
accordance with the formula described below) so that the Base Value immediately
after the time the particular Last Component Stock commences trading ex-
dividend, the effectiveness of the stock split or the time new shares of such
Last Component Stock commence trading equals (a) the Base Value immediately
prior to such event, multiplied by (b) the quotient of the aggregate Market
Value for all Last Component Stocks immediately after such event, divided by the
aggregate Market Value of all Last Component Stocks immediately prior to such
event. The Base Value used by the Calculation Agent to calculate the value
described above will not necessarily be adjusted in all cases in which

                                       9
<PAGE>
 
S&P, in its discretion, might adjust the Base Value (as described below under
"The Standard & Poor's 500 Index-- Computation of the S&P 500 Index").

    If S&P discontinues publication of the S&P 500 Index prior to the period
during which the Supplemental Redemption Amount is to be determined and the
Calculation Agent determines that no Successor Index is available at such time,
then on each Business Day until the earlier to occur of (i) the determination of
the Final Value and (ii) a determination by the Calculation Agent that a
Successor Index is available, the Calculation Agent shall determine the value
that would be used in computing the Supplemental Redemption Amount by reference
to the method set forth in clauses (1) through (6) above as if such day were a
Calculation Day. The Calculation Agent will cause notice of each such value to
be published not less often than once each month in the Wall Street Journal (or
another newspaper of general circulation), and arrange for information with
respect to such values to be made available by telephone. Notwithstanding these
alternative arrangements, discontinuance of the publication of the S&P 500 Index
may adversely affect trading in the Securities.

EVENTS OF DEFAULT AND ACCELERATION

    In case an Event of Default with respect to any Securities shall have
occurred and be continuing, the amount payable to a Holder of a Security upon
any acceleration permitted by the Securities, with respect to each $10 principal
amount thereof, will be equal to: (i) the initial issue price ($10), plus (ii)
an additional amount, if any, of contingent interest calculated as though the
date of early repayment were the maturity date of the Securities. See
"Description of Securities--Payment at Maturity" in this Prospectus. If a
bankruptcy proceeding is commenced in respect of the Company, the claim of the
Holder of a Security may be limited, under Section 502(b)(2) of Title 11 of the
United States Code, to the principal amount of the Security plus an additional
amount, if any, of contingent interest calculated as though the date of the
commencement of the proceeding were the maturity date of the Securities.

    In case of default in payment at the maturity date of the Securities
(whether at their stated maturity or upon acceleration), from and after the
maturity date the Securities shall bear interest, payable upon demand of the
Holders thereof, at the rate of 7% per annum (to the extent that payment of such
interest shall be legally enforceable) on the unpaid amount due and payable on
such date in accordance with the terms of the Securities to the date payment of
such amount has been made or duly provided for.

SECURITIES DEPOSITORY

    Upon issuance, all Securities will be represented by one or more fully
registered global securities (the "Global Securities"). Each such Global
Security will be deposited with, or on behalf of, The Depository Trust Company,
as Securities Depository (the "Securities Depository"), registered in the name
of the Securities Depository or a nominee thereof. Unless and until it is
exchanged in whole or in part for Securities in definitive form, no Global
Security may be transferred except as a whole by the Securities Depository to a
nominee of such Securities Depository or by a nominee of such Securities
Depository to such Securities Depository or another nominee of such Securities
Depository or by such Securities Depository or any such nominee to a successor
of such Securities Depository or a nominee of such successor.

    The Securities Depository has advised the Company as follows: The Securities
Depository is a limited-purpose trust company organized under the Banking Law of
the State of New York, a member of the Federal Reserve System, a "clearing
corporation" within the meaning of the New York Uniform Commercial Code, and a
"clearing agency" registered pursuant to the provisions of Section 17A of the
Exchange Act. The Securities Depository was created to hold securities of its
participants ("Participants") and to facilitate the clearance and settlement of
securities transactions among its Participants in such securities through
electronic book-entry changes in accounts of the Participants, thereby
eliminating the need for physical movement of securities certificates. The
Securities Depository's Participants include securities brokers and dealers,
banks, trust companies, clearing corporations, and certain other organizations.

                                       10
<PAGE>
 
    The Securities Depository is owned by a number of Participants and by the
New York Stock Exchange, Inc., the American Stock Exchange, Inc. and the
National Association of Securities Dealers, Inc. Access to the Securities
Depository book-entry system is also available to others, such as banks,
brokers, dealers and trust companies that clear through or maintain a custodial
relationship with a Participant, either directly or indirectly ("Indirect
Participants").

    Purchases of Securities must be made by or through Participants, which will
receive a credit on the records of the Securities Depository. The ownership
interest of each actual purchaser of each Security ("Beneficial Owner") is in
turn to be recorded on the Participants' or Indirect Participants' records.
Beneficial Owners will not receive written confirmation from the Securities
Depository of their purchase, but Beneficial Owners are expected to receive
written confirmations providing details of the transaction, as well as periodic
statements of their holdings, from the Participant or Indirect Participant
through which the Beneficial Owner entered into the transaction. Ownership of
beneficial interests in such Global Security will be shown on, and the transfer
of such ownership interests will be effected only through, records maintained by
the Securities Depository (with respect to interests of Participants) and on the
records of Participants (with respect to interests of persons held through
Participants). The laws of some states may require that certain purchasers of
securities take physical delivery of such securities in definitive form. Such
limits and such laws may impair the ability to own, transfer or pledge
beneficial interests in Global Securities.

    So long as the Securities Depository, or its nominee, is the registered
owner of a Global Security, the Securities Depository or its nominee, as the
case may be, will be considered the sole owner or Holder of the Securities
represented by such Global Security for all purposes under the Senior Indenture.
Except as provided below, Beneficial Owners in a Global Security will not be
entitled to have the Securities represented by such Global Securities registered
in their names, will not receive or be entitled to receive physical delivery of
the Securities in definitive form and will not be considered the owners or
Holders thereof under the Senior Indenture. Accordingly, each Person owning a
beneficial interest in a Global Security must rely on the procedures of the
Securities Depository and, if such Person is not a Participant, on the
procedures of the Participant through which such Person owns its interest, to
exercise any rights of a Holder under the Senior Indenture. The Company
understands that under existing industry practices, in the event that the
Company requests any action of Holders or that an owner of a beneficial interest
in such a Global Security desires to give or take any action which a Holder is
entitled to give or take under the Senior Indenture, the Securities Depository
would authorize the Participants holding the relevant beneficial interests to
give or take such action, and such Participants would authorize Beneficial
Owners owning through such Participants to give or take such action or would
otherwise act upon the instructions of beneficial owners. Conveyance of notices
and other communications by the Securities Depository to Participants, by
Participants to Indirect Participants, and by Participants and Indirect
Participants to Beneficial Owners will be governed by arrangements among them,
subject to any statutory or regulatory requirements as may be in effect from
time to time.

    Payment of the principal of, and any Supplemental Redemption Amount with
respect to, Securities registered in the name of the Securities Depository or
its nominee will be made to the Securities Depository or its nominee, as the
case may be, as the Holder of the Global Securities representing such
Securities. None of the Company, the Trustee or any other agent of the Company
or agent of the Trustee will have any responsibility or liability for any aspect
of the records relating to or payments made on account of beneficial ownership
interests or for supervising or reviewing any records relating to such
beneficial ownership interests. The Company expects that the Securities
Depository, upon receipt of any payment of principal or any Supplemental
Redemption Amount in respect of a Global Security, will credit the accounts of
the Participants with payment in amounts proportionate to their respective
holdings in principal amount of beneficial interest in such Global Security as
shown on the records of the Securities Depository. The Company also expects that
payments by Participants to Beneficial Owners will be governed by standing
customer instructions and customary practices, as is now the case with
securities held for the accounts of customers in bearer form or registered in
"street name", and will be the responsibility of such Participants.

    If (x) the Securities Depository is at any time unwilling or unable to
continue as Securities Depository and a successor depository is not appointed by
the Company within 60 days, (y) the Company executes and delivers to the Trustee
a Company Order to the effect that the Global Securities shall be exchangeable
or (z) an Event of Default

                                       11
<PAGE>
 
has occurred and is continuing with respect to the Securities, the Global
Securities will be exchangeable for Securities in definitive form of like tenor
and of an equal aggregate principal amount, in denominations of $10 and integral
multiples thereof. Such definitive Securities shall be registered in such name
or names as the Securities Depository shall instruct the Trustee. It is expected
that such instructions may be based upon directions received by the Securities
Depository from Participants with respect to ownership of beneficial interests
in such Global Securities.


                        THE STANDARD & POOR'S 500 INDEX

    All disclosure contained in this Prospectus regarding the S&P 500 Index,
including, without limitation, its make-up, method of calculation and changes in
its components, is derived from publicly available information prepared by S&P
as of May 29, 1992.  The Company takes no responsibility for the accuracy or
completeness of such information.

GENERAL

    The S&P 500 Index is published by S&P and is intended to provide an
indication of the pattern of common stock price movement. The calculation of the
value of the S&P 500 Index (discussed below in further detail) is based on the
relative value of the aggregate Market Value (as defined above) of the common
stocks of 500 companies as of a particular time as compared to the aggregate
average Market Value of the common stocks of 500 similar companies during the
base period of the years 1941 through 1943. As of May 29, 1992, the 500
companies included in the S&P 500 Index represented approximately 76% of the
aggregate Market Value of common stocks traded on The New York Stock Exchange;
however, the 500 companies are not the 500 largest companies listed on The New
York Stock Exchange and not all 500 companies are listed on such exchange. As of
May 29, 1992, the aggregate market value of the 500 companies included in the
S&P 500 Index represented approximately 70% of the aggregate market value of
United States domestic, public companies. S&P chooses companies for inclusion in
the S&P 500 Index with the aim of achieving a distribution by broad industry
groupings that approximates the distribution of these groupings in the common
stock population of The New York Stock Exchange, which S&P uses as an assumed
model for the composition of the total market. Relevant criteria employed by S&P
include the viability of the particular company, the extent to which that
company represents the industry group to which it is assigned, the extent to
which the market price of that company's common stock is generally responsive to
changes in the affairs of the respective industry and the Market Value and
trading activity of the common stock of that company.

COMPUTATION OF THE S&P 500 INDEX

    S&P currently computes the S&P 500 Index as of a particular time as follows:

     (1) the Market Value of each component stock is determined as of such time;

     (2) the Market Value of all component stocks as of such time (as determined
         under clause (1) above) are aggregated;

     (3) the mean average of the Market Values as of each week in the base
         period of the years 1941 through 1943 of the common stock of each
         company in a group of 500 substantially similar companies is
         determined;

     (4) the mean average Market Values of all such common stocks over such base
         period (as determined under clause (3) above) are aggregated (such
         aggregate amount being referred to as the "Base Value");

     (5) the aggregate Market Value of all component stocks as of such time (as
         determined under clause (2) above) is divided by the Base Value; and

     (6) the resulting quotient (expressed in decimals) is multiplied by ten.

                                       12
<PAGE>
 
While S&P currently employs the above methodology to calculate the S&P 500
Index, no assurance can be given that S&P will not modify or change such
methodology in a manner that may affect the Supplemental Redemption Amount, if
any, payable to Holders of Securities upon maturity or otherwise.

  S&P adjusts the foregoing formula to negate the effect of changes in the
Market Value of a component stock that are determined by S&P to be arbitrary or
not due to true market fluctuations. Such changes may result from such causes as
the issuance of stock dividends, the granting to shareholders of rights to
purchase additional shares of such stock, the purchase thereof by employees
pursuant to employee benefit plans, certain consolidations and acquisitions, the
granting to shareholders of rights to purchase other securities of the company,
the substitution by S&P of particular component stocks in the S&P 500 Index, and
other reasons. In all such cases, S&P first recalculates the aggregate Market
Value of all component stocks (after taking account of the new market price per
share of the particular component stock or the new number of outstanding shares
thereof or both, as the case may be) and then determines the New Base Value in
accordance with the following formula:

           Old Base Value   x   New Market Value   =   New Base Value
                                ----------------                     
                                Old Market Value

  The result is that the Base Value is adjusted in proportion to any change in
the aggregate Market Value of all component stocks resulting from the causes
referred to above to the extent necessary to negate the effects of such causes
upon the S&P 500 Index.

  A potential investor should review the historical performance of the S&P 500
Index. The historical performance of the S&P 500 Index should not be taken as an
indication of future performance, and no assurance can be given that the S&P 500
Index will increase sufficiently to cause the beneficial owners of the
Securities to receive an amount in excess of the principal amount at the
maturity of the Securities.

LICENSE AGREEMENT

  S&P and Merrill Lynch Capital Services, Inc. have entered into a non-exclusive
license agreement providing for the license to Merrill Lynch Capital Services,
Inc., in exchange for a fee, of the right to use indices owned and published by
S&P in connection with certain securities, including the Securities, and the
Company is an authorized sublicensee thereof.

  The license agreement between S&P and Merrill Lynch Capital Services, Inc.
provides that the following language must be stated in this Prospectus:

     "The Securities are not sponsored, endorsed, sold or promoted by S&P. S&P
  makes no representation or warranty, express or implied, to the Holders of the
  Securities or any member of the public regarding the advisability of investing
  in securities generally or in the Securities particularly or the ability of
  the S&P 500 Index to track general stock market performance. S&P's only
  relationship to Merrill Lynch Capital Services, Inc. and the Company (other
  than transactions entered into in the ordinary course of business) is the
  licensing of certain service marks and trade names of S&P and of the S&P 500
  Index which is determined, composed and calculated by S&P without regard to
  the Company or the Securities. S&P has no obligation to take the needs of the
  Company or the Holders of the Securities into consideration in determining,
  composing or calculating the S&P 500 Index. S&P is not responsible for and has
  not participated in the determination of the timing of the sale of the
  Securities, prices at which the Securities are to initially be sold, or
  quantities of the Securities to be issued or in the determination or
  calculation of the equation by which the Securities are to be converted into
  cash. S&P has no obligation or liability in connection with the

                                  OTHER TERMS

GENERAL

  The Securities were issued as a series of Senior Debt Securities under the
Indenture (the "Senior Indenture"), dated as of April 1, 1983, as amended and
restated, between the Company and The Chase Manhattan Bank, formerly known as
Chemical Bank (successor by merger to Manufacturers Hanover Trust Company), as
trustee (the "Trustee"). A copy of the Senior Indenture is filed as an exhibit
to the registration statements relating to the Securities. The following
summaries of certain provisions of the Senior Indenture do not purport to be
complete and are subject to, and qualified in their entirety by reference to,
all provisions of the Senior Indenture, including the definition therein of
certain terms.

  The Senior Indenture provides that series of Senior Debt Securities may from
time to time be issued thereunder, without limitation as to aggregate principal
amount, in one or more series and upon such terms as the Company may establish
pursuant to the provisions thereof.

  The Senior Indenture provides that the Senior Indenture and the Securities are
governed by and construed in accordance with the laws of the State of New York.

  The Senior Indenture provides that the Company may issue Senior Debt
Securities with terms different from those of Senior Debt Securities previously
issued, and "reopen" a previously issued series of Senior Debt Securities and
issue additional Senior Debt Securities of such series.

  The Senior Debt Securities are unsecured and rank pari passu with all other
unsecured and unsubordinated indebtedness of the Company.  However, since the
Company is a holding company, the right of the Company, and hence the right of
creditors of the Company (including the Holders of Senior Debt Securities), to
participate in any distribution of the assets of any subsidiary upon its
liquidation or reorganization or otherwise is necessarily subject to the prior
claims of creditors of the subsidiary, except to the extent that claims of the
Company itself as a creditor of the subsidiary may be recognized.  In addition,
dividends, loans and advances from certain subsidiaries, including MLPF&S, to
the Company are restricted by net capital requirements under the Exchange Act
and under rules of certain exchanges and other regulatory bodies.

LIMITATIONS UPON LIENS

  The Company may not, and may not permit any Subsidiary to, create, assume,
incur or permit to exist any indebtedness for borrowed money secured by a
pledge, lien or other encumbrance (except for certain liens specifically
permitted by the Senior Indenture) on the Voting Stock owned directly or
indirectly by the Company of any Subsidiary (other than a Subsidiary which, at
the time of the incurrence of such secured indebtedness, has a net worth of less
than $3,000,000) without making effective provision whereby the Outstanding
Senior Debt Securities will be secured equally and ratably with such secured
indebtedness.

LIMITATION ON DISPOSITION OF VOTING STOCK OF, AND MERGER AND SALE OF ASSETS BY,
MLPF&S

  The Indenture provides that the Company may not sell, transfer or otherwise
dispose of any Voting Stock of MLPF&S or permit MLPF&S to issue, sell or
otherwise dispose of any of its Voting Stock, unless, after giving effect to any
such transaction, MLPF&S remains a Controlled Subsidiary (defined in the Senior
Indenture to mean a corporation more than 80% of the outstanding shares of
Voting Stock of which are owned directly or indirectly by the Company).  In
addition, the Company may not permit MLPF&S to (i) merge or consolidate, unless
the surviving company is a Controlled Subsidiary or (ii) convey or transfer its
properties and assets substantially as an entirety, except to one or more
Controlled Subsidiaries.

                                       14

MERGER AND CONSOLIDATION

  The Indenture provides that the Company may consolidate or merge with or into
any other corporation, and the Company may sell, lease or convey all or
substantially all of its assets to any corporation, provided that (i) the
corporation (if other than the Company) formed by or resulting from any such
consolidation or merger or which shall have received such assets shall be a
corporation organized and existing under the laws of the United States of
America or a state thereof and shall assume payment of the principal of (and
premium, if any) and interest on the Senior Debt Securities and the performance
and observance of all of the covenants and conditions of the Senior Indenture to
be performed or observed by the Company, and (ii) the Company or such successor
corporation, as the case may be, shall not immediately thereafter be in default
under the Senior Indenture.

MODIFICATION AND WAIVER

  Modification and amendment of the Indenture may be effected by the Company and
the Trustee with the consent of the Holders of 66 2/3% in principal amount of
the Outstanding Senior Debt Securities of each series issued pursuant to such
indenture and affected thereby, provided that no such modification or amendment
may, without the consent of the Holder of each Outstanding Senior Debt Security
affected thereby, (a) change the Stated Maturity of the principal of, or any
installment of interest or Additional Amounts payable on, any Senior Debt
Security or any premium payable on the redemption thereof, or change the
Redemption Price; (b) reduce the principal amount of, or the interest or
Additional Amounts payable on, any Senior Debt Security or reduce the amount of
principal which could be declared due and payable prior to the Stated Maturity;
(c) change place or currency of any payment of principal or any premium,
interest or Additional Amounts payable on any Senior Debt Security; (d) impair
the right to institute suit for the enforcement of any payment on or with
respect to any Senior Debt Security; (e) reduce the percentage in principal
amount of the Outstanding Senior Debt Securities of any series, the consent of
whose Holders is required to modify or amend the Indenture; or (f) modify the
foregoing requirements or reduce the percentage of Outstanding Senior Debt
Securities necessary to waive any past default to less than a majority.  No
modification or amendment of the Subordinated Indenture or any Subsequent
Indenture for Subordinated Debt Securities may adversely affect the rights of
any holder of Senior Indebtedness without the consent of such Holder.  Except
with respect to certain fundamental provisions, the Holders of at least a
majority in principal amount of Outstanding Senior Debt Securities of any series
may, with respect to such series, waive past defaults under the Indenture and
waive compliance by the Company with certain provisions thereof.

EVENTS OF DEFAULT

  Under the Senior Indenture, the following will be Events of Default with
respect to Senior Debt Securities of any series: (a) default in the payment of
any interest or Additional Amounts payable on any Senior Debt Security of that
series when due, continued for 30 days; (b) default in the payment of any
principal or premium, if any, on any Senior Debt Security of that series when
due; (c) default in the deposit of any sinking fund payment, when due, in
respect of any Senior Debt Security of that series; (d) default in the
performance of any other covenant of the Company contained in the Indenture for
the benefit of such series or in the Senior Debt Securities of such series,
continued for 60 days after written notice as provided in the Senior Indenture;
(e) certain events in bankruptcy, insolvency or reorganization; and (f) any
other Event of Default provided with respect to Senior Debt Securities of that
series.  The Trustee or the Holders of 25% in principal amount of the
Outstanding Senior Debt Securities of that series may declare the principal
amount (or such lesser amount as may be provided for in the Senior Debt
Securities of that series) of all Outstanding Senior Debt Securities of that
series and the interest due thereon and Additional Amounts payable in respect
thereof, if any to be due and payable immediately if an Event of Default with
respect to Senior Debt Securities of such series shall occur and be continuing
at the time of such declaration.  At any time after a declaration of
acceleration has been made with respect to Senior Debt Securities of any series
but before a judgment or decree for payment of money due has been obtained by
the Trustee, the Holders of a majority in principal amount of the Outstanding
Senior Debt Securities of that series may rescind any declaration of
acceleration and its consequences, if all payments due (other than those due as
a result of acceleration) have been made and all Events of Default have been
remedied or waived.  Any Event of Default with respect to Senior Debt Securities
of

                                       15
<PAGE>
 
any series may be waived by the Holders of a majority in principal amount of all
Outstanding Senior Debt Securities of that series, except in a case of failure
to pay principal or premium, if any, or interest or Additional Amounts payable
on any Senior Debt Security of that series for which payment had not been
subsequently made or in respect of a covenant or provision which cannot be
modified or amended without the consent of the Holder of each Outstanding Senior
Debt Security of such series affected.

  The Holders of a majority in principal amount of the Outstanding Senior Debt
Securities of a series may 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 Senior Debt Securities of such
series, provided that such direction shall not be in conflict with any rule of
law or the Senior Indenture.  Before proceeding to exercise any right or power
under the Senior Indenture at the direction of such Holders, the Trustee shall
be entitled to receive from such Holders reasonable security or indemnity
against the costs, expenses and liabilities which might be incurred by it in
complying with any such direction.

  The Company is required to furnish to the Trustee annually a statement as to
the fulfillment by the Company of all of its obligations under the Senior
Indenture.

                           MERRILL LYNCH & CO., INC.
         STOCK MARKET ANNUAL RESET TERM/SM/ NOTES DUE DECEMBER 31, 1997
                               "SMART NOTES/SM/"

  On October 29, 1992, Merrill Lynch & Co., Inc. (the "Company") issued
$28,000,000 aggregate principal amount of Stock Market Annual Reset Term Notes
due December 31, 1997 (the "SMART Notes", or the "Notes").  The Notes were
issued in denominations of $1,000 and integral multiples thereof, will mature
and be repayable at 100% of the principal amount thereof on December 31, 1997.
Cash payments will be payable with respect to the Notes semiannually on June 30
and December 31 of each year,as described below ("June Payment Dates" and
"December Payment Dates", respectively).

  The Company will make interest payments on the Notes for each year at a rate
per annum equal to 70% of the percent increase,if any, in the S&P 500 Composite
Stock Price Index (the "S&P 500 Index") as determined in each year from the
Starting Annual Value to the Ending Annual Value, as further described herein.
In no event, however, will the annual payments on the Notes be less than $30 per
annum per $1,000 principal amount of Notes (3% per annum) (the "Minimum Annual
Payment") or more than $105 per annum per $1,000 principal amount of Notes
(10.5% per annum) (the "Maximum Annual Payment").  For each $1,000 principal
amount of Notes, the Company will pay $15 on each June Payment Date and will pay
the balance of the annual amount due on the Notes on the December Payment Date.
The Starting Annual Value is reset generally on the first NYSE Business Day (as
defined below) in each calendar year, and, therefore,the amount payable on the
Notes in each calendar year, subject to the Minimum and Maximum Annual Payments,
will be based on a percentage change in the S&P 500 Index occurring during that
year.  The Notes are not subject to redemption by the Holders or the Company
prior to maturity.

  For information as to the calculation of the amount payable in any calendar
year, the calculation of the S&P 500 Index, see "Description of Notes" and "The
Standard & Poor's 500 Index" in this Prospectus.  FOR OTHER INFORMATION THAT
SHOULD BE CONSIDERED BY PROSPECTIVE INVESTORS, SEE "RISK FACTORS" BEGINNING ON
PAGE 4 OF THIS PROSPECTUS.

  Ownership of the Notes will be maintained only in book-entry form by or
through the Securities Depository.  Beneficial owners of the Notes will not have
the right to receive physical certificates evidencing their ownership except
under the limited circumstances described herein.

  The Notes have been listed on the New York Stock Exchange under the symbol
"MERIQ 97".

                                  RISK FACTORS

SEMIANNUAL PAYMENTS

  If the Ending Annual Value applicable to a December Payment Date does not
exceed the Starting Annual Value applicable to such December Payment Date by
more than approximately 4.3%, Holders of the Notes will receive only the Minimum
Annual Payment payable with respect to the Notes, even if the value of the S&P
500 Index at some point between the determination of the applicable Starting
Annual Value and the determination of the applicable Ending Annual Value
exceeded such Starting Annual Value by more than 4.3%. The annual amounts
payable on the Notes based on the S&P 500 Index is limited to 70% of the
percentage increase in such index during any relevant period, and in no event
will such amount exceed the Maximum Annual Payment.

  Holders will receive total annual payments on the Notes equal to not less than
a per annum yield of 3% (the "Minimum Annual Payment"), and will be repaid 100%
of the principal amount of the Notes at maturity. The payment of additional
semiannual amounts are subject to the conditions described under "Description of
Notes--Semiannual Payments". A Holder of the Notes may receive interest payments
with respect to the Notes equal to only the Minimum Annual Payment for each
year, and such interest payments are below what the Company would pay as
interest as of the date hereof if the Company issued non-callable senior debt
securities with a similar maturity as that of the Notes. The return of principal
at maturity and the payment of the Minimum Annual Payment with respect to the
Notes are not expected to reflect the full opportunity costs implied by
inflation or other factors relating to the time value of money.

  The amount payable on the Notes based on the S&P 500 Index will not produce
the same return as if the underlying stocks underlying the S&P 500 Index were
purchased and held for a similar period because of the following: (i) the annual
amount payable on the Notes is limited to 70% of the percentage increase in the
S&P 500 Index during any relevant period and the annual amount payable of the
Notes is subject to a Minimum Annual Payment and a Maximum Annual Payment, (ii)
the S&P 500 Index does not reflect the payment of dividends on the stocks
underlying it, and (iii) the amount payable on the Notes does not reflect any
changes in the S&P 500 Index for the period between the determination of an
Ending Annual Value (generally on the seventh NYSE Business Day prior to the end
of a year) and the determination of the next succeeding Starting Annual Value
(generally on the first NYSE Business Day in the following year).

TRADING

  The Notes are listed on the New York Stock Exchange under the symbol "MERIQ
97". It is expected that the secondary market for the Notes will be affected by
the creditworthiness of the Company and by a number of other factors. It is
possible to view the Notes as the economic equivalent of a debt obligation plus
a series of cash settlement options; however, there can be no assurance that the
Notes will not trade in the secondary market at a discount from the aggregate
value of such economic components, if such economic components were valued and
capable of being traded separately.

  The trading values of the Notes may be affected by a number of interrelated
factors, including those listed below. The following is the expected effect on
the trading value of the Notes of each of the factors listed below. The
following discussion of each separate factor generally assumes that all other
factors are held constant, although the actual interrelationship between certain
of such factors is complex.

  Relative Level of the S&P 500 Index. The trading value of the Notes is
  expected to depend significantly on the extent of the appreciation, if any, of
  the S&P 500 Index over the Annual Starting Value applicable to the next

                                       4
<PAGE>
 
  succeeding December Payment Date. If, however, Notes are sold at a time when
  the S&P 500 Index exceeds the Annual Starting Value, the sale price may be at
  a discount from the amount expected to be payable to the Holder if such excess
  of the S&P 500 Index over such Annual Starting Value were to prevail until the
  next December Payment Date.  Furthermore, the price at which a Holder will be
  able to sell Notes prior to a December Payment Date may be at a discount,
  which could be substantial, from the principal amount thereof, if, at such
  time, the S&P 500 Index is below, equal to or not sufficiently above the
  Annual Starting Value applicable to such December Payment Date. The value of
  the Notes may also be affected by the limitation of the Maximum Annual
  Payment.

  Volatility of the S&P 500 Index. If the volatility of the S&P 500 Index
  increases, the trading value of the Notes is expected to increase. If the
  volatility of the S&P 500 Index decreases, the trading value of the Notes is
  expected to decrease.

  Interest Rates. In general, if U.S. interest rates increase, the value of the
  Notes is expected to decrease. If U.S. interest rates decrease, the value of
  the Notes is generally expected to increase. Interest rates may also affect
  the U.S. economy, and, in turn, the level of the S&P 500 Index. Rising
  interest rates may lower the level of the S&P 500 Index and, thus, the value
  of the Notes. Falling interest rates may increase the level of the S&P 500
  Index and, thus, may increase the value of the Notes.

  Time Remaining to December Payment Dates. The Notes may trade at a value above
  that which may be inferred from the level of interest rates and the S&P 500
  Index. This difference will reflect a "time premium" due to expectations
  concerning the level of the S&P 500 Index during the period prior to each
  December Payment Date. As the time remaining to each December Payment Date
  decreases, however, this time premium may decrease, thus decreasing the
  trading value of the Notes.

  Time Remaining to Maturity. As the number of remaining December Payment Dates
  decreases, the cumulative value of all the S&P Rights will decrease, thus
  decreasing the value of the Notes. Furthermore, as the time to maturity
  decreases, the value of the fixed payments is expected to increase, thus
  increasing the value of the Notes.

  Dividend Rates in the United States. If dividend rates on the stocks
  comprising the S&P 500 Index increase, the value of the S&P Rights is expected
  to decrease. Consequently the value of the Notes is expected to decrease.
  Conversely, if dividend rates on the stocks comprising the S&P 500 Index
  decrease, the value of the S&P Rights is expected to increase and, therefore,
  the value of the Notes is expected to increase. However, in general rising
  U.S. corporate dividend rates may increase the S&P 500 Index and, in turn,
  increase the value of the Notes. Conversely, falling U.S. dividend rates may
  decrease the S&P 500 Index and, in turn, decrease the value of the Notes.

OTHER CONSIDERATIONS

  It is suggested that prospective investors who consider purchasing the Notes
should reach an investment decision only after carefully considering the
suitability of the Notes in the light of their particular circumstances.

  Investors should also consider the tax consequences of investing in the Notes
and should consult their tax advisors.

                              DESCRIPTION OF NOTES

GENERAL

  The Notes were issued as a series of Senior Debt Securities under the Senior
Indenture, dated as of April 1, 1983, as amended and restated, which is more
fully described below.  The Notes will mature, and the principal of the Notes
will be repayable at par, on December 31, 1997.

  The Notes are not subject to redemption prior to maturity by the Company or at
the option of any Holder.  Upon the occurrence of an Event of Default with
respect to the Notes, however, Holders of the Notes or the Senior Debt Trustee
may accelerate the maturity of the Notes, as described under "Description of
Notes--Events of Default and Acceleration" and "Other Terms--Events of Default"
in the this Prospectus.

  The Notes were issued in denominations of $1,000 and integral multiples
thereof.

SEMIANNUAL PAYMENTS

  The Company will make semiannual interest payments on the Notes each June 30
and December 31 ("June Payment Dates" and "December Payment Dates",
respectively), as described below, to the persons in whose names the Notes are
registered on the next preceding June 29 or December 30, except as provided
below. Notwithstanding the foregoing, if it is known three Business Days prior
to December 31 that December 31 will not be a Business Day, the amount payable
by the Company with respect to such December Payment Date will be made on the
Business Day immediately preceding such December 31 to the persons in whose
names the Notes are registered on the second Business Day immediately preceding
such December 31.

  For each calendar year, the Company will pay an amount equal to the following
for each $1,000 principal amount of Notes:

                     (  ENDING ANNUAL VALUE-STARTING ANNUAL VALUE  ) 
          $1,000  X  (  -----------------------------------------  )  X 70%
                     (           STARTING ANNUAL VALUE             )

provided, however, that the per annum amount payable as a result of the
foregoing will not be less than $30 per $1,000 principal amount of Notes (3% per
annum) (the "Minimum Annual Payment") or greater than $105 per $1,000 principal
amount of Notes (10.5% per annum) (the "Maximum Annual Payment"). For each
$1,000 principal amount of the Notes, the Company will pay $15 of the total
amount payable for each calendar year on the June Payment Date, and will pay the
balance of the annual amount due on the Notes for such year on the December
Payment Date.  The "Starting Annual Value" applicable to the determination of
the amount payable in a calendar year will equal the closing value of the S&P
500 Index on the first NYSE Business Day (as defined herein) in such year on
which a Market Disruption Event has not occurred as determined by State Street
Bank and Trust Company (the "Calculation Agent"); provided, however, that if a
Market Disruption Event shall have occurred on each of the first ten NYSE
Business Days in any year, the "Starting Annual Value" applicable to the
determination of the amount payable in such year will equal the closing value of
the S&P 500 Index on such tenth NYSE Business Day.  The "Ending Annual Value"
applicable to the determination of the amount payable in a calendar year will
equal the closing value of the S&P 500 Index on the seventh scheduled NYSE
Business Day preceding the end of such year (including December 31 if it is a
scheduled NYSE Business Day) as determined by the Calculation Agent, unless a
Market Disruption Event has occurred on such day. In the event that a Market
Disruption Event has occurred on the seventh scheduled NYSE Business Day
preceding the end of such year, the "Ending Annual Value" applicable to the
determination of the amount payable in such year will equal the closing value of
the S&P 500 Index on the sixth scheduled NYSE Business Day preceding the end of
such year regardless of whether such day is a NYSE Business Day or a Market
Disruption Event occurs on such day. The Calculation Agent will determine the
seventh

                                       6
<PAGE>
 
scheduled NYSE Business Day, and, if necessary, the sixth scheduled NYSE
Business Day prior to each December Payment Date.

     If the Ending Annual Value applicable to a December Payment Date does not
exceed the applicable Starting Annual Value by more than approximately 4.3%,
Holders of the Notes will receive only the Minimum Annual Payment payable with
respect to the Notes, even if the value of the S&P 500 Index at some point
between the determination of the applicable Starting Annual Value and the
determination of the applicable Ending Annual Value exceeded such Starting
Annual Value by more than 4.3%. If the Ending Annual Value applicable to a
December Payment Date exceeds the applicable Starting Annual Value by 15% or
more, Holders of Notes will receive the Maximum Amount Payable with respect to
the Notes. The Holders will receive not less than the Minimum Annual Payment (3%
per annum) even in the event that the Ending Annual Value is less than the
Starting Annual Value in any year.

     Any day on which a Starting Annual Value or an Ending Annual Value is
required to be calculated is referred to herein as a "Calculation Day". A "NYSE
Business Day" is a day on which The New York Stock Exchange is open for trading.
All determinations made by the Calculation Agent shall be at the sole discretion
of the Calculation Agent and, in the absence of manifest error, shall be
conclusive for all purposes and binding on the Company and Holders of the Notes.

     "Market Disruption Event" means either of the following events, as
determined by the Calculation Agent:

     (i) the material limitation (limitations pursuant to New York Stock
  Exchange Rule 80A (or any applicable rule or regulation enacted or promulgated
  by the New York Stock Exchange, any other self-regulatory organization or the
  Commission of similar scope as determined by the Calculation Agent) on trading
  during significant market fluctuations shall be considered "material" for
  purposes of this definition) or suspension, in each case, for more than two
  hours of trading in 100 or more of the securities included in the S&P 500
  Index, or

     (ii) the suspension or material limitation, in each case, for more than two
  hours of trading (whether by reason of movements in price otherwise exceeding
  levels permitted by the relevant exchange or otherwise) in (A) futures
  contracts related to the S&P 500 Index which are traded on the Chicago
  Mercantile Exchange or (B) option contracts related to the S&P 500 Index which
  are traded on the Chicago Board Options Exchange, Inc.

     For the purposes of this definition, a limitation on the hours in a trading
day and/or number of days of trading will not constitute a Market Disruption
Event if it results from an announced change in the regular business hours of
the relevant exchange.

     If S&P discontinues publication of the S&P 500 Index and S&P or another
entity publishes a successor or substitute index that the Calculation Agent
determines, in its sole discretion, to be comparable to the S&P 500 Index (any
such index being referred to hereinafter as a "Successor Index"), then, upon the
Calculation Agent's notification of such determination to the Trustee and the
Company, the Calculation Agent will substitute the Successor Index as calculated
by S&P or such other entity for the S&P 500 Index and calculate the Starting
Annual Value and/or the Ending Annual Value as described above. Upon any
selection by the Calculation Agent of a Successor Index, the Company shall cause
notice thereof to be published in The Wall Street Journal (or another newspaper
of general circulation) within three Business Days of such selection.

     If S&P discontinues publication of the S&P 500 Index and a Successor Index
is not selected by the Calculation Agent or is no longer published on any of the
Calculation Days, the value to be substituted for the S&P 500 Index for any such
Calculation Day used to calculate the Starting Annual Value or Ending Annual
Value, as the case may be, will be calculated as described below under
"Discontinuance of the S&P 500 Index."

                                       7
<PAGE>
 
     If a Successor Index is selected or the Calculation Agent calculates a
value as a substitute for the S&P 500 Index as described below, such Successor
Index or value shall be substituted for the S&P 500 Index for all purposes.

     If at any time the method of calculating the S&P 500 Index, or the value
thereof, is changed in a material respect, or if the S&P 500 Index is in any
other way modified so that such Index does not, in the opinion of the
Calculation Agent, fairly represent the value of the S&P 500 Index had such
changes or modifications not been made, then, from and after such time, the
Calculation Agent shall, at the close of business in New York, New York, on each
Calculation Date, make such adjustments as, in the good faith judgment of the
Calculation Agent, may be necessary in order to arrive at a calculation of a
value of a stock index comparable to the S&P 500 Index as if such changes or
modifications had not been made, and calculate such closing value with reference
to the S&P 500 Index, as adjusted. Accordingly, if the method of calculating the
S&P 500 Index is modified so that the value of such Index is a fraction or a
multiple of what it would have been if it had not been modified (e.g., due to a
split in the Index), then the Calculation Agent shall adjust such Index in order
to arrive at a value of the S&P 500 Index as if it had not been modified (e.g.,
as if such split had not occurred).

     The following table is an example of hypothetical annual payments on the
SMART Notes using assumed changes in the S&P 500 Index. The numbers below are
shown for illustrative purposes only and are not intended to predict either the
future levels of the S&P 500 Index or the payments to be received on the Notes.

     The above information is for purposes of illustration only. The actual
amount payable in any year on the Notes will depend entirely on the Starting
Annual Value and Ending Annual Value applicable to such year determined by the
Calculation Agent as provided herein and the Minimum Annual Payment and the
Maximum Annual Payment.

     A potential investor should review the historical performance of the S&P
500 Index.  The historical performance of the S&P 500 Index should not be taken
as an indication of future performance, and no assurance can be given that the
S&P 500 Index will increase sufficiently during any calendar year to cause the
beneficial owners of the Notes to receive an amount in excess of the Minimum
Annual Payment during any such calendar year.

DISCONTINUANCE OF THE S&P 500 INDEX AND SUCCESSOR INDEX

     If S&P discontinues publication of the S&P 500 Index and a Successor Index
is available, then the amount payable on any December Payment Date will be
determined by reference to the Successor Index, as provided above.

                                       8
<PAGE>
 
     If the publication of the S&P 500 Index is discontinued and S&P or another
entity does not publish a Successor Index on any of the Calculation Days, the
value to be substituted for the S&P 500 Index for any such Calculation Day will
be the value computed by the Calculation Agent for each such Calculation Day in
accordance with the following procedures:

     (1) identifying the component stocks of the S&P 500 Index or any Successor
  Index as of the last date on which either of such indices was calculated by
  S&P or another entity and published by S&P or such other entity (each such
  component stock is a "Last Component Stock");

     (2) for each Last Component Stock, calculating as of each such NYSE
  Business Day the product of the market price per share and the number of the
  then outstanding shares (such product referred to as the "Market Value" of
  such stock), by reference to (a) the closing market price per share of such
  Last Component Stock as quoted by the New York Stock Exchange or the American
  Stock Exchange or any other registered national securities exchange that is
  the primary market for such Last Component Stock, or if no such quotation is
  available, then the closing market price as quoted by any other registered
  national securities exchange or the National Association of Securities Dealers
  Automated Quotation National Market System ("NASDAQ"), or if no such price is
  quoted, then the market price from the best available source as determined by
  the Calculation Agent (collectively, the "Exchanges") and (b) the most recent
  publicly available statement of the number of outstanding shares of such Last
  Component Stock;

     (3) aggregating the Market Values obtained in clause (2) for all Last
  Component Stocks;

     (4) ascertaining the Base Value (as defined below under "The Standard &
  Poor's 500 Index--Computation of the S&P 500 Index") in effect as of the last
  day on which either the S&P 500 Index or any Successor Index was published by
  S&P or another entity, adjusted as described below;

     (5) dividing the aggregate Market Value of all Last Component Stocks by the
  Base Value (adjusted as aforesaid);

     (6) multiplying the resulting quotient (expressed in decimals) by ten.

     If any Last Component Stock is no longer publicly traded on any registered
national securities exchange or in the over-the-counter market, the last
available market price per share for such Last Component Stock as quoted by any
registered national securities exchange or in the over-the-counter market, and
the number of outstanding shares thereof at such time, will be used in computing
the last available Market Value of such Last Component Stock. Such Market Value
will be used in all computations of the S&P 500 Index thereafter.

     If a company that has issued a Last Component Stock and another company
that has issued a Last Component Stock are consolidated to form a new company,
the common stock of such new company will be considered a Last Component Stock
and the common stocks of the constituent companies will no longer be considered
Last Component Stocks. If any company that has issued a Last Component Stock
merges with, or acquires, a company that has not issued a Last Component Stock,
the common stock of the surviving corporation will, upon the effectiveness of
such merger or acquisition, be considered a Last Component Stock. In each such
case, the Base Value will be adjusted so that the Base Value immediately after
such consolidation, merger or acquisition will equal (a) the Base Value
immediately prior to such event, multiplied by (b) the quotient of the aggregate
Market Value of all Last Component Stocks immediately after such event, divided
by the aggregate Market Value for all Last Component Stocks immediately prior to
such event.

     If a company that has issued a Last Component Stock issues a stock
dividend, declares a stock split or issues new shares pursuant to the
acquisition of another company, then, in each case, the Base Value will be
adjusted (in accordance with the formula described below) so that the Base Value
immediately after the time the particular Last Component Stock commences trading
ex-dividend, the effectiveness of the stock split or the time new

                                       9
<PAGE>
 
shares of such Last Component Stock commence trading equals (a) the Base Value
immediately prior to such event, multiplied by (b) the quotient of the aggregate
Market Value for all Last Component Stocks immediately after such event, divided
by the aggregate Market Value of all Last Component Stocks immediately prior to
such event. The Base Value used by the Calculation Agent to calculate the value
described above will not necessarily be adjusted in all cases in which S&P, in
its discretion, might adjust the Base Value (as described below under "The
Standard & Poor's 500 Index--Computation of the S&P 500 Index").

     If S&P discontinues publication of the S&P 500 Index prior to the period
during which the amount payable with respect to any year is to be determined and
the Calculation Agent determines that no Successor Index is available at such
time, then on each NYSE Business Day until the earlier to occur of (i) the
determination of the amount payable with respect to such year and (ii) a
determination by the Calculation Agent that a Successor Index is available, the
Calculation Agent shall determine the value that would be used in computing the
amount payable with respect to such year by reference to the method set forth in
clauses (1) through (6) above as if such day were a Calculation Day. The
Calculation Agent will cause notice of each such value to be published not less
often than once each month in the Wall Street Journal (or another newspaper of
general circulation), and arrange for information with respect to such values to
be made available by telephone. Notwithstanding these alternative arrangements,
discontinuance of the publication of the S&P 500 Index may adversely affect
trading in the Notes.

EVENTS OF DEFAULT AND ACCELERATION

     In case an Event of Default with respect to any Notes shall have occurred
and be continuing, the amount payable to a Holder of a Note upon any
acceleration permitted by the Notes, will equal: (i) the principal amount
thereof, plus (ii) an additional amount, if any, calculated as though the date
of early repayment were a December Payment Date and prorated through such date
of early repayment. If a bankruptcy proceeding is commenced in respect of the
Company, the claim of the Holder of a Note may be limited, under Section
502(b)(2) of Title 11 of the United States Code, to the principal amount of the
Note plus an additional amount, if any, of contingent interest calculated as
though the date of the commencement of the proceeding were the maturity date of
the Notes.

SECURITIES DEPOSITORY

     Upon issuance, all Notes will be represented by one or more fully
registered global securities (the "Global Securities"). Each such Global
Security will be deposited with, or on behalf of, The Depository Trust Company,
as Securities Depository (the "Securities Depository"), registered in the name
of the Securities Depository or a nominee thereof. Unless and until it is
exchanged in whole or in part for Securities in definitive form, no Global
Security may be transferred except as a whole by the Securities Depository to a
nominee of such Securities Depository or by a nominee of such Securities
Depository to such Securities Depository or another nominee of such Securities
Depository or by such Securities Depository or any such nominee to a successor
of such Securities Depository or a nominee of such successor.

     The Securities Depository has advised the Company as follows: The
Securities Depository is a limited-purpose trust company organized under the
Banking Law of the State of New York, a member of the Federal Reserve System, a
"clearing corporation" within the meaning of the New York Uniform Commercial
Code, and a "clearing agency" registered pursuant to the provisions of Section
17A of the Exchange Act.  The Securities Depository was created to hold
securities of its participants ("Participants") and to facilitate the clearance
and settlement of securities transactions among its Participants in such
securities through electronic book-entry changes in accounts of the
Participants, thereby eliminating the need for physical movement of securities
certificates. The Securities Depository's Participants include securities
brokers and dealers, banks, trust companies, clearing corporations, and certain
other organizations. The Securities Depository is owned by a number of
Participants and by the New York Stock Exchange, Inc., the American Stock
Exchange, Inc. and the National Association of Securities Dealers, Inc.  Access
to the Securities Depository book-entry system is also available to others, such
as banks, brokers, dealers and trust companies that clear through or maintain a
custodial relationship with a Participant, either directly or indirectly
("Indirect Participants").

                                       10
<PAGE>
 
     Purchases of Notes must be made by or through Participants, which will
receive a credit on the records of the Securities Depository. The ownership
interest of each actual purchaser of each Note ("Beneficial Owner") is in turn
to be recorded on the Participants' or Indirect Participants' records.
Beneficial Owners will not receive written confirmation from the Securities
Depository of their purchase, but Beneficial Owners are expected to receive
written confirmations providing details of the transaction, as well as periodic
statements of their holdings, from the Participant or Indirect Participant
through which the Beneficial Owner entered into the transaction. Ownership of
beneficial interests in such Global Security will be shown on, and the transfer
of such ownership interests will be effected only through, records maintained by
the Securities Depository (with respect to interests of Participants) and on the
records of Participants (with respect to interests of persons held through
Participants). The laws of some states may require that certain purchasers of
securities take physical delivery of such securities in definitive form. Such
limits and such laws may impair the ability to own, transfer or pledge
beneficial interests in Global Securities.

     So long as the Securities Depository, or its nominee, is the registered
owner of a Global Security, the Securities Depository or its nominee, as the
case may be, will be considered the sole owner or Holder of the Notes
represented by such Global Security for all purposes under the Senior Indenture.
Except as provided below, Beneficial Owners in a Global Security will not be
entitled to have the Notes represented by such Global Securities registered in
their names, will not receive or be entitled to receive physical delivery of the
Notes in definitive registered form and will not be considered the owners or
Holders thereof under the Senior Indenture.  Accordingly, each Person owning a
beneficial interest in a Global Security must rely on the procedures of the
Securities Depository and, if such Person is not a Participant, on the
procedures of the Participant through which such Person owns its interest, to
exercise any rights of a Holder under the Senior Indenture. The Company
understands that under existing industry practices, in the event that the
Company requests any action of Holders or that an owner of a beneficial interest
in such a Global Security desires to give or take any action which a Holder is
entitled to give or take under the Senior Indenture, the Securities Depository
would authorize the Participants holding the relevant beneficial interests to
give or take such action, and such Participants would authorize Beneficial
Owners owning through such Participants to give or take such action or would
otherwise act upon the instructions of beneficial owners. Conveyance of notices
and other communications by the Securities Depository to Participants, by
Participants to Indirect Participants, and by Participants and Indirect
Participants to Beneficial Owners will be governed by arrangements among them,
subject to any statutory or regulatory requirements as may be in effect from
time to time.

     Payment of the principal of, and amounts payable on any June Payment Date
or December Payment Date with respect to, Notes registered in the name of the
Securities Depository or its nominee will be made to the Securities Depository
or its nominee, as the case may be, as the Holder of the Global Securities
representing such Notes. None of the Company, the Trustee or any other agent of
the Company or agent of the Trustee will have any responsibility or liability
for any aspect of the records relating to or payments made on account of
beneficial ownership interests or for supervising or reviewing any records
relating to such beneficial ownership interests. The Company expects that the
Securities Depository, upon receipt of any payment of principal or amounts
payable on any June Payment Date or December Payment Date in respect of a Global
Security, will credit the accounts of the Participants with payment in amounts
proportionate to their respective holdings in principal amount of beneficial
interest in such Global Security as shown on the records of the Securities
Depository. The Company also expects that payments by Participants to Beneficial
Owners will be governed by standing customer instructions and customary
practices, as is now the case with securities held for the accounts of customers
in bearer form or registered in "street name", and will be the responsibility of
such Participants.

     If (x) the Securities Depository is at any time unwilling or unable to
continue as Securities Depository and a successor depository is not appointed by
the Company within 60 days, (y) the Company executes and delivers to the Trustee
a Company Order to the effect that the Global Securities shall be exchangeable
or (z) an Event of Default has occurred and is continuing with respect to the
Notes, the Global Securities will be exchangeable for Notes in definitive form
of like tenor and of an equal aggregate principal amount, in denominations of
$1,000 and integral multiples thereof. Such definitive Notes shall be registered
in such name or names as the Securities Depository shall instruct the Trustee.
It is expected that such instructions may be based upon directions received

                                       11
<PAGE>

                        THE STANDARD & POOR'S 500 INDEX

     All disclosure contained in this Prospectus regarding the S&P 500 Index,
including, without limitation, its make-up, method of calculation and changes in
its components, is derived from publicly available information prepared by S&P
as of September 21, 1992.  The Company cannot assure the accuracy or
completeness of the information prepared by S&P.

GENERAL

     The S&P 500 Index is published by S&P and is intended to provide an
indication of the pattern of common stock price movement. The calculation of the
value of the S&P 500 Index (discussed below in further detail) is based on the
relative value of the aggregate Market Value (as defined above) of the common
stocks of 500 companies as of a particular time as compared to the aggregate
average Market Value of the common stocks of 500 similar companies during the
base period of the years 1941 through 1943. As of August 31, 1992, the 500
companies included in the S&P 500 Index represented approximately 76% of the
aggregate Market Value of common stocks traded on The New York Stock Exchange;
however, the 500 companies are not the 500 largest companies listed on The New
York Stock Exchange and not all 500 companies are listed on such exchange. As of
August 31, 1992, the aggregate market value of the 500 companies included in the
S&P 500 Index represented approximately 70% of the aggregate market value of
United States domestic, public companies. S&P chooses companies for inclusion in
the S&P 500 Index with the aim of achieving a distribution by broad industry
groupings that approximates the distribution of these groupings in the common
stock population of The New York Stock Exchange, which S&P uses as an assumed
model for the composition of the total market. Relevant criteria employed by S&P
include the viability of the particular company, the extent to which that
company represents the industry group to which it is assigned, the extent to
which the market price of that company's common stock is generally responsive to
changes in the affairs of the respective industry and the Market Value and
trading activity of the common stock of that company.

COMPUTATION OF THE S&P 500 INDEX

  S&P currently computes the S&P 500 Index as of a particular time as follows:

     (1) the Market Value of each component stock is determined as of such time;

     (2) the Market Values of all component stocks as of such time (as
  determined under clause (1) above) are aggregated;

     (3) the mean average of the Market Values as of each week in the base
  period of the years 1941 through 1943 of the common stock of each company in a
  group of 500 substantially similar companies is determined;

     (4) the mean average Market Values of all such common stocks over such base
  period (as determined under clause (3) above) are aggregated (such aggregate
  amount being referred to as the "Base Value");

     (5) the aggregate Market Value of all component stocks as of such time (as
  determined under clause (2) above) is divided by the Base Value; and

     (6) the resulting quotient (expressed in decimals) is multiplied by ten.

                                       12
<PAGE>
 
While S&P currently employs the above methodology to calculate the S&P 500
Index, no assurance can be given that S&P will not modify or change such
methodology in a manner that may affect the amounts payable on any December
Payment Date to Holders of Notes.

     S&P adjusts the foregoing formula to negate the effect of changes in the
Market Value of a component stock that are determined by S&P to be arbitrary or
not due to true market fluctuations. Such changes may result from such causes as
the issuance of stock dividends, the granting to shareholders of rights to
purchase additional shares of such stock, the purchase thereof by employees
pursuant to employee benefit plans, certain consolidations and acquisitions, the
granting to shareholders of rights to purchase other securities of the company,
the substitution by S&P of particular component stocks in the S&P 500 Index, and
other reasons. In all such cases, S&P first recalculates the aggregate Market
Value of all component stocks (after taking account of the new market price per
share of the particular component stock or the new number of outstanding shares
thereof or both, as the case may be) and then determines the New Base Value in
accordance with the following formula:

                             New Market Value 
          Old Base Value X   ----------------   = New Base Value
                             Old Market Value

The result is that the Base Value is adjusted in proportion to any change in the
aggregate Market Value of all component stocks resulting from the causes
referred to above to the extent necessary to negate the effects of such causes
upon the S&P 500 Index.

     A potential investor should review the historical performance of the S&P
500 Index. The historical performance of the S&P 500 Index should not be taken
as an indication of future performance, and no assurance can be given that the
S&P 500 Index will increase sufficiently to cause the beneficial owners of the
Notes to receive an amount in excess of the principal amount at the maturity of
the Notes.

LICENSE AGREEMENT

     S&P and Merrill Lynch Capital Services, Inc. have entered into a non-
exclusive license agreement providing for the license to Merrill Lynch Capital
Services, Inc., in exchange for a fee, of the right to use indices owned and
published by S&P in connection with certain securities, including the Notes, and
the Company is an authorized sublicensee thereof.

     The license agreement between S&P and Merrill Lynch Capital Services, Inc.
provides that the following language must be stated in this Prospectus:

          "The Notes are not sponsored, endorsed, sold or promoted by S&P. S&P
     makes no representation or warranty, express or implied, to the Holders of
     the Notes or any member of the public regarding the advisability of
     investing in securities generally or in the Notes particularly or the
     ability of the S&P 500 Index to track general stock market performance.
     S&P's only relationship to Merrill Lynch Capital Services, Inc. and the
     Company (other then transactions entered into in the ordinary course of
     business) is the licensing of certain servicemarks and trade names of S&P
     and of the S&P 500 Index which is determined, composed and calculated by
     S&P without regard to the Company or the Notes. S&P has no obligation to
     take the needs of the Company or the Holders of the Notes into
     consideration in determining, composing or calculating the S&P 500 Index.
     S&P is not responsible for and has not participated in the determination of
     the timing of the sale of the Notes, prices at which the Notes are to
     initially be sold, or quantities of the Notes to be issued or in the
     determination or calculation of the equation by which the Notes are to be
     converted into cash. S&P has no obligation or liability in connection with
     the administration, marketing or trading of the Notes."

                                 OTHER TERMS

GENERAL

     The Securities were issued as a series of Senior Debt Securities under the
Indenture (the "Senior Indenture"), dated as of April 1, 1983, as amended and
restated, between the Company and The Chase Manhattan Bank, formerly known as
Chemical Bank (successor by merger to Manufacturers Hanover Trust Company), as
trustee (the "Trustee"). A copy of the Senior Indenture is filed as an exhibit
to the registration statements relating to the Securities. The following
summaries of certain provisions of the Senior Indenture do not purport to be
complete and are subject to, and qualified in their entirety by reference to,
all provisions of the Senior Indenture, including the definition therein of
certain terms.

     The Senior Indenture provides that series of Senior Debt Securities may
from time to time be issued thereunder, without limitation as to aggregate
principal amount, in one or more series and upon such terms as the Company may
establish pursuant to the provisions thereof.

     The Senior Indenture provides that the Senior Indenture and the Securities
are governed by and construed in accordance with the laws of the State of New
York.

     The Senior Indenture provides that the Company may issue Senior Debt
Securities with terms different from those of Senior Debt Securities previously
issued, and "reopen" a previously issued series of Senior Debt Securities and
issue additional Senior Debt Securities of such series.

     The Senior Debt Securities are unsecured and rank pari passu with all other
unsecured and unsubordinated indebtedness of the Company.  However, since the
Company is a holding company, the right of the Company, and hence the right of
creditors of the Company (including the Holders of Senior Debt Securities), to
participate in any distribution of the assets of any subsidiary upon its
liquidation or reorganization or otherwise is necessarily subject to the prior
claims of creditors of the subsidiary, except to the extent that claims of the
Company itself as a creditor of the subsidiary may be recognized.  In addition,
dividends, loans and advances from certain subsidiaries, including MLPF&S, to
the Company are restricted by net capital requirements under the Exchange Act
and under rules of certain exchanges and other regulatory bodies.

LIMITATIONS UPON LIENS

     The Company may not, and may not permit any Subsidiary to, create, assume,
incur or permit to exist any indebtedness for borrowed money secured by a
pledge, lien or other encumbrance (except for certain liens specifically
permitted by the Senior Indenture) on the Voting Stock owned directly or
indirectly by the Company of any Subsidiary (other than a Subsidiary which, at
the time of the incurrence of such secured indebtedness, has a net worth of less
than $3,000,000) without making effective provision whereby the Outstanding
Senior Debt Securities will be secured equally and ratably with such secured
indebtedness.

LIMITATION ON DISPOSITION OF VOTING STOCK OF, AND MERGER AND SALE OF ASSETS BY,
MLPF&S

     The Indenture provides that the Company may not sell, transfer or otherwise
dispose of any Voting Stock of MLPF&S or permit MLPF&S to issue, sell or
otherwise dispose of any of its Voting Stock, unless, after giving effect to any
such transaction, MLPF&S remains a Controlled Subsidiary (defined in the Senior
Indenture to mean a corporation more than 80% of the outstanding shares of
Voting Stock of which are owned directly or indirectly by the Company).  In
addition, the Company may not permit MLPF&S to (i) merge or consolidate, unless
the surviving company is a Controlled Subsidiary or (ii) convey or transfer its
properties and assets substantially as an entirety, except to one or more
Controlled Subsidiaries.

                                       14
<PAGE>
 
MERGER AND CONSOLIDATION

     The Indenture provides that the Company may consolidate or merge with or
into any other corporation, and the Company may sell, lease or convey all or
substantially all of its assets to any corporation, provided that (i) the
corporation (if other than the Company) formed by or resulting from any such
consolidation or merger or which shall have received such assets shall be a
corporation organized and existing under the laws of the United States of
America or a state thereof and shall assume payment of the principal of (and
premium, if any) and interest on the Senior Debt Securities and the performance
and observance of all of the covenants and conditions of the Senior Indenture to
be performed or observed by the Company, and (ii) the Company or such successor
corporation, as the case may be, shall not immediately thereafter be in default
under the Senior Indenture.

MODIFICATION AND WAIVER

     Modification and amendment of the Indenture may be effected by the Company
and the Trustee with the consent of the Holders of 66 2/3% in principal amount
of the Outstanding Senior Debt Securities of each series issued pursuant to such
indenture and affected thereby, provided that no such modification or amendment
may, without the consent of the Holder of each Outstanding Senior Debt Security
affected thereby, (a) change the Stated Maturity of the principal of, or any
installment of interest or Additional Amounts payable on, any Senior Debt
Security or any premium payable on the redemption thereof, or change the
Redemption Price; (b) reduce the principal amount of, or the interest or
Additional Amounts payable on, any Senior Debt Security or reduce the amount of
principal which could be declared due and payable prior to the Stated Maturity;
(c) change place or currency of any payment of principal or any premium,
interest or Additional Amounts payable on any Senior Debt Security; (d) impair
the right to institute suit for the enforcement of any payment on or with
respect to any Senior Debt Security; (e) reduce the percentage in principal
amount of the Outstanding Senior Debt Securities of any series, the consent of
whose Holders is required to modify or amend the Indenture; or (f) modify the
foregoing requirements or reduce the percentage of Outstanding Senior Debt
Securities necessary to waive any past default to less than a majority.  No
modification or amendment of the Subordinated Indenture or any Subsequent
Indenture for Subordinated Debt Securities may adversely affect the rights of
any holder of Senior Indebtedness without the consent of such Holder.  Except
with respect to certain fundamental provisions, the Holders of at least a
majority in principal amount of Outstanding Senior Debt Securities of any series
may, with respect to such series, waive past defaults under the Indenture and
waive compliance by the Company with certain provisions thereof.

EVENTS OF DEFAULT

     Under the Senior Indenture, the following will be Events of Default with
respect to Senior Debt Securities of any series: (a) default in the payment of
any interest or Additional Amounts payable on any Senior Debt Security of that
series when due, continued for 30 days; (b) default in the payment of any
principal or premium, if any, on any Senior Debt Security of that series when
due; (c) default in the deposit of any sinking fund payment, when due, in
respect of any Senior Debt Security of that series; (d) default in the
performance of any other covenant of the Company contained in the Indenture for
the benefit of such series or in the Senior Debt Securities of such series,
continued for 60 days after written notice as provided in the Senior Indenture;
(e) certain events in bankruptcy, insolvency or reorganization; and (f) any
other Event of Default provided with respect to Senior Debt Securities of that
series.  The Trustee or the Holders of 25% in principal amount of the
Outstanding Senior Debt Securities of that series may declare the principal
amount (or such lesser amount as may be provided for in the Senior Debt
Securities of that series) of all Outstanding Senior Debt Securities of that
series and the interest due thereon and Additional Amounts payable in respect
thereof, if any to be due and payable immediately if an Event of Default with
respect to Senior Debt Securities of such series shall occur and be continuing
at the time of such declaration.  At any time after a declaration of
acceleration has been made with respect to Senior Debt Securities of any series
but before a judgment or decree for payment of money due has been obtained by
the Trustee, the Holders of a majority in principal amount of the Outstanding
Senior Debt Securities of that series may rescind any declaration of
acceleration and its consequences, if all payments due (other than those due as
a result of acceleration) have been made and all Events of Default have been
remedied or waived.  Any Event of Default with respect to Senior Debt

                                       15
<PAGE>
 
Securities of any series may be waived by the Holders of a majority in principal
amount of all Outstanding Senior Debt Securities of that series, except in a
case of failure to pay principal or premium, if any, or interest or Additional
Amounts payable on any Senior Debt Security of that series for which payment had
not been subsequently made or in respect of a covenant or provision which cannot
be modified or amended without the consent of the Holder of each Outstanding
Senior Debt Security of such series affected.

     The Holders of a majority in principal amount of the Outstanding Senior
Debt Securities of a series may 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 Senior Debt Securities of such
series, provided that such direction shall not be in conflict with any rule of
law or the Senior Indenture.  Before proceeding to exercise any right or power
under the Senior Indenture at the direction of such Holders, the Trustee shall
be entitled to receive from such Holders reasonable security or indemnity
against the costs, expenses and liabilities which might be incurred by it in
complying with any such direction.

     The Company is required to furnish to the Trustee annually a statement as
to the fulfillment by the Company of all of its obligations under the Senior
Indenture.

         S&P 500 MARKET INDEX TARGET-TERM SECURITIES/SM/ DUE JULY 31, 1998
                                  ("MITTS(R)")

   On January 28, 1993, Merrill Lynch & Co., Inc. (the "Company") issued
$16,000,000 aggregate principal amount (1,600,000 Units) of S&P 500 Market Index
Target-Term Securities due July 31, 1998 (the "Securities or MITTS").  Each $10
principal amount of the Securities will be deemed a "Unit" for purposes of
trading and transfer at the Securities Depository described below. Units will be
transferable by the Securities Depository, as more fully described below, in
denominations of whole Units.

  The Securities were offered at an original issue price of 100% of the
principal amount thereof, will bear no periodic payments of interest and will
mature on July 31, 1998. At maturity, a Holder of a Security will be entitled to
receive, with respect to each Security, the principal amount thereof, plus a
contingent interest payment (the "Supplemental Redemption Amount"), if any, if
the Final Value (as defined herein) of the S&P 500 Composite Stock Price Index
(the "S&P 500 Index") exceeds 435.49 (the "Initial Value"). If the Final Value
does not exceed the Initial Value, a Holder of a Security will be repaid the
principal amount of the Security, but the Holder will not receive any
Supplemental Redemption Amount. While at maturity a beneficial owner of a
Security may receive an amount in excess of the principal amount of such
Security if the Final Value exceeds the Initial Value, there will be no payment
of interest, periodic or otherwise, prior to maturity.  The Securities were
issued as a series of Senior Debt Securities under the Senior Indenture
described herein. The Securities are not redeemable prior to maturity.

  The Supplemental Redemption Amount, if any, payable with respect to a Security
at maturity will equal the product of (A) the principal amount of the applicable
Security, and (B) the quotient of the Final Value less the Initial Value,
divided by the Initial Value, and (C) 115%. The calculation of the Final Value,
as more fully described herein, will be based upon certain values of the S&P 500
Index during the ten Business Days prior to the maturity date of the Securities.

  For information as to the calculation of the Supplemental Redemption Amount,
if any, which will be paid at maturity, the calculation and the composition of
the S&P 500 Index, see "Description of Securities" and "The Standard & Poor's
500 Index" in this Prospectus. FOR OTHER INFORMATION THAT SHOULD BE CONSIDERED
BY PROSPECTIVE INVESTORS, SEE "RISK FACTORS" BEGINNING ON PAGE 4 OF THIS
PROSPECTUS.

  Ownership of the Securities will be maintained in book-entry form by or
through the Securities Depository. Beneficial owners of the Securities will not
have the right to receive physical certificates evidencing their ownership
except under the limited circumstances described herein.

   The Securities have been listed on the New York Stock Exchange under the
symbol "MIE".

  For the purpose of calculating the ratio of earnings to fixed charges,
"earnings" consists of earnings from continuing operations before income taxes
and fixed charges.  "Fixed charges" consists of interest costs, amortization of
debt expense, preferred stock dividend requirements of majority-owned
subsidiaries, and that portion of rentals estimated to be representative of the
interest factor.


                                  RISK FACTORS

PAYMENT AT MATURITY

  If the Final Value is equal to or less than the Initial Value, the Holders of
the Securities will be entitled to receive $10 in respect of each $10 principal
amount of Securities, and no Supplemental Redemption Amount. This will be true
even though the value of the S&P 500 Index as of some interim period or periods
prior to the maturity date of the Securities may have exceeded the Initial Value
because the Supplemental Redemption Amount on the Securities is calculated on
the basis of the Final Value only.

  The $10 minimum to be received by Holders at maturity in respect of each $10
principal amount of a Security does not reflect any opportunity cost implied by
inflation and other factors relating to the time value of money.

  The S&P 500 Index does not reflect the payment of dividends on the stocks
underlying it and therefore the yield based on the S&P 500 Index to the maturity
of the Securities will not produce the same yield as if such underlying stocks
were purchased and held for a similar period.

TRADING

  The Securities have been listed on the New York Stock Exchange under the
symbol "MIE".  It is expected that the secondary market for the Securities will
be affected by the creditworthiness of the Company and by a number of other
factors.

  The trading value of the Securities is expected to depend primarily on the
extent of the appreciation, if any, of the S&P 500 Index over the Initial Value.
If, however, Securities are sold prior to the maturity date at a time when the
S&P 500 Index exceeds the Initial Value, the sale price may be at a discount
from the amount expected to be payable to the Holder if such excess of the S&P
500 Index over the Initial Value were to prevail until maturity of the
Securities because of the possible fluctuation of the S&P 500 Index between the
time of such sale and the maturity date. (See "The Standard & Poor's 500
Index".)  Furthermore, the price at which a Holder will be able to sell
Securities prior to maturity may be at a discount, which could be substantial,
from the principal amount thereof, if, at such time, the S&P 500 Index is below,
equal to or not sufficiently above the Initial Value. A discount could also
result from rising interest rates.

  The trading values of the Securities may be affected by a number of
interrelated factors, including the creditworthiness of the Company and those
factors listed below. The relationship among these factors is complex, including
how these factors affect the relative value of the principal amount of the
Securities to be repaid at maturity and the value of the Supplemental Redemption
Amount. Accordingly, investors should be aware that factors other than the level
of the S&P 500 Index are likely to affect their trading value. The expected
effect on the trading value of the Securities of each of the factors listed
below, assuming in each case that all other factors are held constant, is as
follows:

  Interest Rates. In general, if U.S. interest rates increase, the value of the
  Securities is expected to decrease. If U.S. interest rates decrease, the value
  of the Securities is expected to increase. Interest rates may also affect the
  U.S. economy, and, in turn, the value of the S&P 500 Index. Rising interest
  rates may lower the value of

                                       4
<PAGE>
 
  the S&P 500 Index and, thus, the Securities. Falling interest rates may
  increase the value of the S&P 500 Index and, thus, may increase the value of
  the Securities.

  Volatility of the S&P 500 Index. If the volatility of the S&P 500 Index
  increases, the trading value of the Securities is expected to increase. If the
  volatility of the S&P 500 Index decreases, the trading value of the Securities
  is expected to decrease.

  Time Remaining to Maturity. The Securities may trade at a value above that
  which may be inferred from the level of interest rates and the S&P 500 Index.
  This difference will reflect a "time premium" due to expectations concerning
  the value of the S&P 500 Index during the period prior to maturity of the
  Securities. As the time remaining to maturity of the Securities decreases,
  however, this time premium is expected to decrease, thus decreasing the
  trading value of the Securities.

  Dividend Rates in the United States. If dividend rates on the stocks
  comprising the S&P 500 Index increase, the value of the Securities is expected
  to decrease. Conversely, if dividend rates on the stocks comprising the S&P
  500 Index decrease, the value of the Securities is expected to increase.
  However, in general, rising U.S. corporate dividend rates may increase the S&P
  500 Index and, in turn, increase the value of the Securities. Conversely,
  falling U.S. dividend rates may decrease the S&P 500 Index and, in turn,
  decrease the value of the Securities.

OTHER CONSIDERATIONS

  It is suggested that prospective investors who consider purchasing the
Securities should reach an investment decision only after carefully considering
the suitability of the Securities in the light of their particular
circumstances.

  Investors should also consider the tax consequences of investing in the
Securities and should consult their tax advisors.


                           DESCRIPTION OF SECURITIES
GENERAL

  The Securities were issued as a series of Senior Debt Securities under the
Senior Indenture, dated as of April 1, 1983, as amended and restated, as
described below.  The principal amount of each Security equals $10 for each $10
original price to the public.  The Securities will mature on July 31, 1998.

  While at maturity a beneficial owner of a Security may receive an amount in
excess of the principal amount of such Security if the Final Value exceeds the
Initial Value, there will be no payment of interest, periodic or otherwise,
prior to maturity.

  The Securities are not subject to redemption by the Company or at the option
of any Holder prior to maturity. Upon the occurrence of an Event of Default with
respect to the Securities, Holders of the Securities may accelerate the maturity
of the Securities, as described under "Description of Securities-Events of
Default and Acceleration" and "Other Terms-Events of Default" in this
Prospectus.

  The Securities were issued in denominations of whole Units.

                                       5
<PAGE>
 
PAYMENT AT MATURITY

  At maturity, a Holder of a Security will be entitled to receive the principal
amount thereof ($10 for each $10 price to public) plus a Supplemental Redemption
Amount, if any, all as provided below. If the Final Value of the S&P 500 Index
does not exceed the Initial Value, a Holder of a Security will be repaid the
principal amount of the Security at maturity, but will not be entitled to
receive any contingent interest (i.e., Supplemental Redemption Amount).

  At maturity, a Holder of a Security will be entitled to receive, with respect
to each such Security, (i) the principal amount thereof, and (ii) the
Supplemental Redemption Amount, if any, equal in amount to:

               Principal  X  (Final Value - Initial Value) X 115%
                              ---------------------------        
                                    Initial Value

provided, however, that the Supplemental Redemption Amount will not be less than
zero. The Initial Value of the S&P 500 Index is 435.49. If the Final Value does
not exceed the Initial Value, the Supplemental Redemption Amount will equal zero
and a Holder of a Security will receive only the principal amount thereof ($10
for each $10 price to public).

  The Final Value of the S&P 500 Index will be determined by State Street Bank
and Trust Company (the "Calculation Agent") and will equal the average (mean) of
the closing values of the S&P 500 Index as calculated by S&P on the tenth
Business Day (as defined below) prior to the maturity date (provided that a
Market Disruption Event, as defined below, shall not have occurred on such day)
and on each succeeding Business Day (provided that a Market Disruption Event
shall not have occurred on the applicable day) up to and including the fourth
Business Day prior to the maturity date (each, a "Calculation Day") until the
Calculation Agent has so determined such closing values for five Business Days.
If a Market Disruption Event occurs on one or more of the Business Days during
the period specified above, the Final Value will equal the average of the values
on Business Days on which a Market Disruption Event did not occur or, if there
is only one such Business Day, the value on such day. If Market Disruption
Events occur on all of such Business Days during such period, the Final Value
shall equal the closing value of the S&P 500 Index on the fourth Business Day
prior to the maturity date regardless of whether a Market Disruption Event shall
have occurred on such day. For purposes of determining the Final Value, a
"Business Day" is a day on which The New York Stock Exchange is open for
trading. All determinations made by the Calculation Agent shall be at the sole
discretion of the Calculation Agent and, in the absence of manifest error, shall
be conclusive for all purposes and binding on the Company and Holders of the
Securities.

  If S&P discontinues publication of the S&P 500 Index and S&P or another entity
publishes a successor or substitute index that the Calculation Agent determines,
in its sole discretion, to be comparable to the S&P 500 Index (any such index
being referred to hereinafter as a "Successor Index"), then, upon the
Calculation Agent's notification of such determination to the Trustee and the
Company, the Calculation Agent will substitute the Successor Index as calculated
by S&P or such other entity for the S&P 500 Index and calculate the Final Value
as described in the preceding paragraph. Upon any selection by the Calculation
Agent of a Successor Index, the Company shall cause notice thereof to be
published in The Wall Street Journal (or another newspaper of general
circulation) within three Business Days of such selection.

  If S&P discontinues publication of the S&P 500 Index and a Successor Index is
not selected by the Calculation Agent or is no longer published on any of the
Calculation Days, the value to be substituted for the S&P 500 Index for any such
Calculation Day used to calculate the Supplemental Redemption Amount, if any, at
maturity will be calculated as described below under "Discontinuance of the S&P
500 Index".

                                       6
<PAGE>
 
  If a Successor Index is selected or the Calculation Agent calculates a value
as a substitute for the S&P 500 Index as described below, such Successor Index
or value shall be substituted for the S&P 500 Index for all purposes, including
for purposes of determining whether a Market Disruption Event exists.

  If at any time the method of calculating the S&P 500 Index, or the value
thereof, is changed in a material respect, or if the S&P 500 Index is in any
other way modified so that such Index does not, in the opinion of the
Calculation Agent, fairly represent the value of the S&P 500 Index had such
changes or modifications not been made, then, from and after such time, the
Calculation Agent shall, at the close of business in New York, New York, on each
date that the closing value with respect to the Final Value is to be calculated,
make such adjustments as, in the good faith judgment of the Calculation Agent,
may be necessary in order to arrive at a calculation of a value of a stock index
comparable to the S&P 500 Index as if such changes or modifications had not been
made, and calculate such closing value with reference to the S&P 500 Index, as
adjusted. Accordingly, if the method of calculating the S&P 500 Index is
modified so that the value of such Index is a fraction or a multiple of what it
would have been if it had not been modified (e.g., due to a split in the Index),
then the Calculation Agent shall adjust such Index in order to arrive at a value
of the S&P 500 Index as if it had not been modified (e.g., as if such split had
not occurred).

  "Market Disruption Event" means either of the following events, as determined
by the Calculation Agent:

     (i) the material limitation (limitations pursuant to New York Stock
  Exchange Rule 80A (or any applicable rule or regulation enacted or promulgated
  by the New York Stock Exchange, any other self regulatory organization or the
  Securities and Exchange Commission of similar scope as determined by the
  Calculation Agent) on trading during significant market fluctuations shall be
  considered "material" for purposes of this definition) or suspension, in each
  case, for more than two hours of trading in 100 or more of the securities
  included in the S&P 500 Index, or

     (ii) the suspension or material limitation, in each case, for more than two
  hours of trading (whether by reason of movements in price otherwise exceeding
  levels permitted by the relevant exchange or otherwise) in (A) futures
  contracts related to the S&P 500 Index which are traded on the Chicago
  Mercantile Exchange or (B) option contracts related to the S&P 500 Index which
  are traded on the Chicago Board Options Exchange, Inc.

  For the purposes of this definition, a limitation on the hours in a trading
day and/or number of days of trading will not constitute a Market Disruption
Event if it results from an announced change in the regular business hours of
the relevant exchange.

  The following table illustrates, for a range of hypothetical Final Values, the
percentage change in the S&P 500 Index from the date of pricing of the
Securities offered hereby until maturity, the Supplemental Redemption Amount at
maturity for each $10 principal amount of Securities.

(1) Initial Value.

  The above figures are for purposes of illustration only. The actual
Supplemental Redemption Amount received by investors and the pretax annualized
rate of return resulting therefrom will depend entirely on the actual Final
Value determined by the Calculation Agent as provided herein.

  The Senior Indenture provides that the Senior Indenture and the Notes will be
governed by and construed in accordance with the laws of the State of New York.
Under present New York law, the maximum rate of interest is 25% per annum on a
simple interest basis. This limit may not apply to Securities in which
$2,500,000 or more has been invested. While the Company believes that New York
law would be given effect by a state or federal court sitting outside of New
York, state laws frequently regulate the amount of interest that may be charged
to and paid by a borrower (including, in some cases, corporate borrowers). All
payments under the Securities (other than the return of principal) could be
considered interest for the purpose of state usury laws.  The Company has
covenanted for the benefit of the Holders of the Notes, to the extent permitted
by law, not to claim voluntarily the benefits of any laws concerning usurious
rates of interest against a Holder of the Securities.

DISCONTINUANCE OF THE S&P 500 INDEX AND SUCCESSOR INDEX

  If S&P discontinues publication of the S&P 500 Index and a Successor Index is
available, then the amount payable at maturity or upon earlier acceleration will
be determined by reference to the Successor Index, as provided above.

  If the publication of the S&P 500 Index is discontinued and S&P or another
entity does not publish a Successor Index on any of the Calculation Days, the
value to be substituted for the S&P 500 Index for any such Calculation Day used
to calculate the Supplemental Redemption Amount, if any, at maturity will be the
value computed by the Calculation Agent for each such Calculation Day in
accordance with the following procedures:

                                       8
<PAGE>
 
     (1) identifying the component stocks of the S&P 500 Index or any Successor
  Index as of the last date on which either of such indices was calculated by
  S&P or another entity and published by S&P or such other entity (each such
  component stock is a "Last Component Stock");

     (2) for each Last Component Stock, calculating as of each such Calculation
  Day the product of the market price per share and the number of the then
  outstanding shares (such product referred to as the "Market Value" of such
  stock), by reference to (a) the closing market price per share of such Last
  Component Stock as quoted by the New York Stock Exchange or the American Stock
  Exchange or any other registered national securities exchange that is the
  primary market for such Last Component Stock, or if no such quotation is
  available, then the closing market price as quoted by any other registered
  national securities exchange or the National Association of Securities Dealers
  Automated Quotation National Market System ("NASDAQ"), or if no such price is
  quoted, then the market price from the best available source as determined by
  the Calculation Agent (collectively, the "Exchanges") and (b) the most recent
  publicly available statement of the number of outstanding shares of such Last
  Component Stock;

     (3) aggregating the Market Values obtained in clause (2) for all Last
  Component Stocks;

     (4) ascertaining the Base Value (as defined below under "The Standard &
  Poor's 500 Index--Computation of the Index") in effect as of the last day on
  which either the S&P 500 Index or any Successor Index was published by S&P or
  another entity, adjusted as described below;

     (5) dividing the aggregate Market Value of all Last Component Stocks by the
  Base Value (adjusted as aforesaid);

     (6) multiplying the resulting quotient (expressed in decimals) by ten.

  If any Last Component Stock is no longer publicly traded on any registered
national securities exchange or in the over-the-counter market, the last
available market price per share for such Last Component Stock as quoted by any
registered national securities exchange or in the over-the-counter market, and
the number of outstanding shares thereof at such time, will be used in computing
the last available Market Value of such Last Component Stock. Such Market Value
will be used in all computations of the S&P 500 Index thereafter.
 
  If a company that has issued a Last Component Stock and another company that
has issued a Last Component Stock are consolidated to form a new company, the
common stock of such new company will be considered a Last Component Stock and
the common stocks of the constituent companies will no longer be considered Last
Component Stocks. If any company that has issued a Last Component Stock merges
with, or acquires, a company that has not issued a Last Component Stock, the
common stock of the surviving corporation will, upon the effectiveness of such
merger or acquisition, be considered a Last Component Stock. In each such case,
the Base Value will be adjusted so that the Base Value immediately after such
consolidation, merger or acquisition will equal (a) the Base Value immediately
prior to such event, multiplied by (b) the quotient of the aggregate Market
Value of all Last Component Stocks immediately after such event, divided by the
aggregate Market Value for all Last Component Stocks immediately prior to such
event.

  If a company that has issued a Last Component Stock issues a stock dividend,
declares a stock split or issues new shares pursuant to the acquisition of
another company, then, in each case, the Base Value will be adjusted (in
accordance with the formula described below) so that the Base Value immediately
after the time the particular Last Component Stock commences trading ex-
dividend, the effectiveness of the stock split or the time new shares of such
Last Component Stock commence trading equals (a) the Base Value immediately
prior to such event, multiplied by (b) the quotient of the aggregate Market
Value for all Last Component Stocks immediately after such event, divided by the
aggregate Market Value of all Last Component Stocks immediately prior to such
event. The Base Value used by the Calculation Agent to calculate the value
described above will not necessarily be adjusted in all cases in which S&P, in
its discretion, might adjust the Base Value (as described below under "The
Standard & Poor's 500 Index--Computation of the S&P 500 Index").

                                       9
<PAGE>
 
  If S&P discontinues publication of the S&P 500 Index prior to the period
during which the Supplemental Redemption Amount is to be determined and the
Calculation Agent determines that no Successor Index is available at such time,
then on each Business Day until the earlier to occur of (i) the determination of
the Final Value and (ii) a determination by the Calculation Agent that a
Successor Index is available, the Calculation Agent shall determine the value
that would be used in computing the Supplemental Redemption Amount by reference
to the method set forth in clauses (1) through (6) in the fourth preceding
paragraph above as if such day were a Calculation Day. The Calculation Agent
will cause notice of each such value to be published not less often than once
each month in the Wall Street Journal (or another newspaper of general
circulation), and arrange for information with respect to such values to be made
available by telephone. Notwithstanding these alternative arrangements,
discontinuance of the publication of the S&P 500 Index may adversely affect
trading in the Securities.

EVENTS OF DEFAULT AND ACCELERATION

  In case an Event of Default with respect to any Securities shall have occurred
and be continuing, the amount payable to a Holder of a Security upon any
acceleration permitted by the Securities, with respect to each $10 principal
amount thereof, will be equal to: (i) the initial issue price ($10), plus (ii)
an additional amount, if any, of contingent interest calculated as though the
date of early repayment were the maturity date of the Securities. See
"Description of Securities--Payment at Maturity" in this Prospectus. If a
bankruptcy proceeding is commenced in respect of the Company, the claim of the
Holder of a Security may be limited, under Section 502(b)(2) of Title 11 of the
United States Code, to the principal amount of the Security plus an additional
amount, if any, of contingent interest calculated as though the date of the
commencement of the proceeding were the maturity date of the Securities.

  In case of default in payment at the maturity date of the Securities (whether
at their stated maturity or upon acceleration), from and after the maturity date
the Securities shall bear interest, payable upon demand of the Holders thereof,
at the rate of 7% per annum (to the extent that payment of such interest shall
be legally enforceable) on the unpaid amount due and payable on such date in
accordance with the terms of the Securities to the date payment of such amount
has been made or duly provided for.

SECURITIES DEPOSITORY

  Upon issuance, all Securities will be represented by one or more fully
registered global securities (the "Global Securities"). Each such Global
Security will be deposited with, or on behalf of, The Depository Trust Company,
as Securities Depository (the "Securities Depository"), registered in the name
of the Securities Depository or a nominee thereof. Unless and until it is
exchanged in whole or in part for Securities in definitive form, no Global
Security may be transferred except as a whole by the Securities Depository to a
nominee of such Securities Depository or by a nominee of such Securities
Depository to such Securities Depository or another nominee of such Securities
Depository or by such Securities Depository or any such nominee to a successor
of such Securities Depository or a nominee of such successor.

  The Securities Depository has advised the Company as follows: The Securities
Depository is a limited-purpose trust company organized under the Banking Law of
the State of New York, a member of the Federal Reserve System, a "clearing
corporation" within the meaning of the New York Uniform Commercial Code, and a
"clearing agency" registered pursuant to the provisions of Section 17A of the
Exchange Act.  The Securities Depository was created to hold securities of its
participants ("Participants") and to facilitate the clearance and settlement of
securities transactions among its Participants in such securities through
electronic book-entry changes in accounts of the Participants, thereby
eliminating the need for physical movement of securities certificates. The
Securities Depository's Participants include securities brokers and dealers,
banks, trust companies, clearing corporations, and certain other organizations.
The Securities Depository is owned by a number of Participants and by the New
York Stock Exchange, Inc., the American Stock Exchange, Inc. and the National
Association of Securities Dealers, Inc. Access

                                       10
<PAGE>
 
to the Securities Depository book-entry system is also available to others, such
as banks, brokers, dealers and trust companies that clear through or maintain a
custodial relationship with a Participant, either directly or indirectly
("Indirect Participants").

  Purchases of Securities must be made by or through Participants, which will
receive a credit on the records of the Securities Depository. The ownership
interest of each actual purchaser of each Security ("Beneficial Owner") is in
turn to be recorded on the Participants' or Indirect Participants' records.
Beneficial Owners will not receive written confirmation from the Securities
Depository of their purchase, but Beneficial Owners are expected to receive
written confirmations providing details of the transaction, as well as periodic
statements of their holdings, from the Participant or Indirect Participant
through which the Beneficial Owner entered into the transaction. Ownership of
beneficial interests in such Global Security will be shown on, and the transfer
of such ownership interests will be effected only through, records maintained by
the Securities Depository (with respect to interests of Participants) and on the
records of Participants (with respect to interests of persons held through
Participants). The laws of some states may require that certain purchasers of
securities take physical delivery of such securities in definitive form. Such
limits and such laws may impair the ability to own, transfer or pledge
beneficial interests in Global Securities.

  So long as the Securities Depository, or its nominee, is the registered owner
of a Global Security, the Securities Depository or its nominee, as the case may
be, will be considered the sole owner or Holder of the Securities represented by
such Global Security for all purposes under the Senior Indenture. Except as
provided below, Beneficial Owners in a Global Security will not be entitled to
have the Securities represented by such Global Securities registered in their
names, will not receive or be entitled to receive physical delivery of the
Securities in definitive form and will not be considered the owners or Holders
thereof under the Senior Indenture. Accordingly, each Person owning a beneficial
interest in a Global Security must rely on the procedures of the Securities
Depository and, if such Person is not a Participant, on the procedures of the
Participant through which such Person owns its interest, to exercise any rights
of a Holder under the Senior Indenture. The Company understands that under
existing industry practices, in the event that the Company requests any action
of Holders or that an owner of a beneficial interest in such a Global Security
desires to give or take any action which a Holder is entitled to give or take
under the Senior Indenture, the Securities Depository would authorize the
Participants holding the relevant beneficial interests to give or take such
action, and such Participants would authorize Beneficial Owners owning through
such Participants to give or take such action or would otherwise act upon the
instructions of Beneficial Owners. Conveyance of notices and other
communications by the Securities Depository to Participants, by Participants to
Indirect Participants, and by Participants and Indirect Participants to
Beneficial Owners will be governed by arrangements among them, subject to any
statutory or regulatory requirements as may be in effect from time to time.

  Payment of the principal of, and any Supplemental Redemption Amount with
respect to, Securities registered in the name of the Securities Depository or
its nominee will be made to the Securities Depository or its nominee, as the
case may be, as the Holder of the Global Securities representing such
Securities. None of the Company, the Trustee or any other agent of the Company
or agent of the Trustee will have any responsibility or liability for any aspect
of the records relating to or payments made on account of beneficial ownership
interests or for supervising or reviewing any records relating to such
beneficial ownership interests. The Company expects that the Securities
Depository, upon receipt of any payment of principal or any Supplemental
Redemption Amount in respect of a Global Security, will credit the accounts of
the Participants with payment in amounts proportionate to their respective
holdings in principal amount of beneficial interest in such Global Security as
shown on the records of the Securities Depository. The Company also expects that
payments by Participants to Beneficial Owners will be governed by standing
customer instructions and customary practices, as is now the case with
securities held for the accounts of customers in bearer form or registered in
"street name", and will be the responsibility of such Participants.

                                       11
<PAGE>
 
  If (x) the Securities Depository is at any time unwilling or unable to
continue as Securities Depository and a successor depository is not appointed by
the Company within 60 days, (y) the Company executes and delivers to the Trustee
a Company Order to the effect that the Global Securities shall be exchangeable
or (z) an Event of Default has occurred and is continuing with respect to the
Securities, the Global Securities will be exchangeable for Securities in
definitive form of like tenor and of an equal aggregate principal amount, in
denominations of $10 and integral multiples thereof. Such definitive Securities
shall be registered in such name or names as the Securities Depository shall
instruct the Trustee. It is expected that such instructions may be based upon
directions received by the Securities Depository from Participants with respect
to ownership of beneficial interests in such Global Securities.


                        THE STANDARD & POOR'S 500 INDEX

  All disclosure contained in this Prospectus regarding the S&P 500 Index,
including, without limitation, its make-up, method of calculation and changes in
its components, is derived from publicly available information prepared by S&P
as of December 31, 1992.  The Company takes no responsibility for the accuracy
or completeness of such information.

GENERAL

  The S&P 500 Index is published by S&P and is intended to provide an indication
of the pattern of common stock price movement. The calculation of the value of
the S&P 500 Index (discussed below in further detail) is based on the relative
value of the aggregate Market Value (as defined above) of the common stocks of
500 companies as of a particular time as compared to the aggregate average
Market Value of the common stocks of 500 similar companies during the base
period of the years 1941 through 1943. As of December 31, 1992, the 500
companies included in the S&P 500 Index represented approximately 76% of the
aggregate Market Value of common stocks traded on The New York Stock Exchange;
however, the 500 companies are not the 500 largest companies listed on The New
York Stock Exchange and not all 500 companies are listed on such exchange. As of
December 31, 1992, the aggregate market value of the 500 companies included in
the S&P 500 Index represented approximately 70% of the aggregate market value of
United States domestic, public companies. S&P chooses companies for inclusion in
the S&P 500 Index with the aim of achieving a distribution by broad industry
groupings that approximates the distribution of these groupings in the common
stock population of The New York Stock Exchange, which S&P uses as an assumed
model for the composition of the total market. Relevant criteria employed by S&P
include the viability of the particular company, the extent to which that
company represents the industry group to which it is assigned, the extent to
which the market price of that company's common stock is generally responsive to
changes in the affairs of the respective industry and the Market Value and
trading activity of the common stock of that company.

COMPUTATION OF THE S&P 500 INDEX

   S&P computes the S&P 500 Index as of a particular time as follows:

     (1) the Market Value of each component stock is determined as of such time;

     (2) the Market Value of all component stocks as of such time (as determined
         under clause (1) above) are aggregated;

     (3) the mean average of the Market Values as of each week in the base
         period of the years 1941 through 1943 of the common stock of each
         company in a group of 500 substantially similar companies is
         determined;

     (4) the mean average Market Values of all such common stocks over such base
         period (as determined under clause (3) above) are aggregated (such
         aggregate amount being referred to as the "Base Value");

                                       12
<PAGE>
 
     (5) the aggregate Market Value of all component stocks as of such time (as
         determined under clause (2) above) is divided by the Base Value; and

     (6) the resulting quotient (expressed in decimals) is multiplied by ten.

While S&P employs the above methodology to calculate the S&P 500 Index, no
assurance can be given that S&P will not modify or change such methodology in a
manner that may affect the Supplemental Redemption Amount, if any, payable to
Holders of Securities upon maturity or otherwise.

  S&P adjusts the foregoing formula to negate the effect of changes in the
Market Value of a component stock that are determined by S&P to be arbitrary or
not due to true market fluctuations. Such changes may result from such causes as
the issuance of stock dividends, the granting to shareholders of rights to
purchase additional shares of such stock, the purchase thereof by employees
pursuant to employee benefit plans, certain consolidations and acquisitions, the
granting to shareholders of rights to purchase other securities of the company,
the substitution by S&P of particular component stocks in the S&P 500 Index, and
other reasons. In all such cases, S&P first recalculates the aggregate Market
Value of all component stocks (after taking account of the new market price per
share of the particular component stock or the new number of outstanding shares
thereof or both, as the case may be) and then determines the New Base Value in
accordance with the following formula:

           Old Base Value   x   New Market Value   =   New Base Value
                                ----------------                     
                                Old Market Value


  The result is that the Base Value is adjusted in proportion to any change in
the aggregate Market Value of all component stocks resulting from the causes
referred to above to the extent necessary to negate the effects of such causes
upon the S&P 500 Index.

  A potential investor should review the historical performance of the S&P 500
Index. The historical performance of the S&P 500 Index should not be taken as an
indication of future performance, and no assurance can be given that the S&P 500
Index will increase sufficiently to cause the beneficial owners of the
Securities to receive a Supplemental Redemption Amount at the maturity of the
Securities.

LICENSE AGREEMENT

  S&P and Merrill Lynch Capital Services, Inc. have entered into a non-exclusive
license agreement providing for the license to Merrill Lynch Capital Services,
Inc., in exchange for a fee, of the right to use indices owned and published by
S&P in connection with certain securities, including the Securities, and the
Company is an authorized sublicensee thereof.

  The license agreement between S&P and Merrill Lynch Capital Services, Inc.
provides that the following language must be stated in this Prospectus:

     "The Securities are not sponsored, endorsed, sold or promoted by S&P. S&P
  makes no representation or warranty, express or implied, to the Holders of the
  Securities or any member of the public regarding the advisability of investing
  in securities generally or in the Securities particularly or the ability of
  the S&P 500 Index to track general stock market performance. S&P's only
  relationship to Merrill Lynch Capital Services, Inc. and the Company (other
  then transactions entered into in the ordinary course of business) is the
  licensing of certain service marks and trade names of S&P and of the S&P 500
  Index which is determined, composed and calculated by S&P without regard to
  the Company or the Securities. S&P has no obligation to take the needs

                                       13
<PAGE>
 
  of the Company or the Holders of the Securities into consideration in
  determining, composing or calculating the S&P 500 Index. S&P is not
  responsible for and has not participated in the determination of the timing of
  the sale of the Securities, prices at which the Securities are to initially be
  sold, or quantities of the Securities to be issued or in the determination or
  calculation of the equation by which the Securities are to be converted into
  cash. S&P has no obligation or liability in connection with the
  administration, marketing or trading of the Securities."


                                  OTHER TERMS
GENERAL

  The Securities were issued as a series of Senior Debt Securities under the
Indenture (the "Senior Indenture"), dated as of April 1, 1983, as amended and
restated, between the Company and The Chase Manhattan Bank, formerly known as
Chemical Bank (successor by merger to Manufacturers Hanover Trust Company), as
trustee (the "Trustee"). A copy of the Senior Indenture is filed as an exhibit
to the registration statements relating to the Securities. The following
summaries of certain provisions of the Senior Indenture do not purport to be
complete and are subject to, and qualified in their entirety by reference to,
all provisions of the Senior Indenture, including the definition therein of
certain terms.

  The Senior Indenture provides that series of Senior Debt Securities may from
time to time be issued thereunder, without limitation as to aggregate principal
amount, in one or more series and upon such terms as the Company may establish
pursuant to the provisions thereof.

  The Senior Indenture provides that the Senior Indenture and the Securities are
governed by and construed in accordance with the laws of the State of New York.

  The Senior Indenture provides that the Company may issue Senior Debt
Securities with terms different from those of Senior Debt Securities previously
issued, and "reopen" a previously issued series of Senior Debt Securities and
issue additional Senior Debt Securities of such series.

  The Senior Debt Securities are unsecured and rank pari passu with all other
unsecured and unsubordinated indebtedness of the Company.  However, since the
Company is a holding company, the right of the Company, and hence the right of
creditors of the Company (including the Holders of Senior Debt Securities), to
participate in any distribution of the assets of any subsidiary upon its
liquidation or reorganization or otherwise is necessarily subject to the prior
claims of creditors of the subsidiary, except to the extent that claims of the
Company itself as a creditor of the subsidiary may be recognized.  In addition,
dividends, loans and advances from certain subsidiaries, including MLPF&S, to
the Company are restricted by net capital requirements under the Exchange Act
and under rules of certain exchanges and other regulatory bodies.

LIMITATIONS UPON LIENS

  The Company may not, and may not permit any Subsidiary to, create, assume,
incur or permit to exist any indebtedness for borrowed money secured by a
pledge, lien or other encumbrance (except for certain liens specifically
permitted by the Senior Indenture) on the Voting Stock owned directly or
indirectly by the Company of any Subsidiary (other than a Subsidiary which, at
the time of the incurrence of such secured indebtedness, has a net worth of less
than $3,000,000) without making effective provision whereby the Outstanding
Senior Debt Securities will be secured equally and ratably with such secured
indebtedness.

                                       14
<PAGE>
 
LIMITATION ON DISPOSITION OF VOTING STOCK OF, AND MERGER AND SALE OF ASSETS BY,
MLPF&S

  The Indenture provides that the Company may not sell, transfer or otherwise
dispose of any Voting Stock of MLPF&S or permit MLPF&S to issue, sell or
otherwise dispose of any of its Voting Stock, unless, after giving effect to any
such transaction, MLPF&S remains a Controlled Subsidiary (defined in the Senior
Indenture to mean a corporation more than 80% of the outstanding shares of
Voting Stock of which are owned directly or indirectly by the Company).  In
addition, the Company may not permit MLPF&S to (i) merge or consolidate, unless
the surviving company is a Controlled Subsidiary or (ii) convey or transfer its
properties and assets substantially as an entirety, except to one or more
Controlled Subsidiaries.

MERGER AND CONSOLIDATION

  The Indenture provides that the Company may consolidate or merge with or into
any other corporation, and the Company may sell, lease or convey all or
substantially all of its assets to any corporation, provided that (i) the
corporation (if other than the Company) formed by or resulting from any such
consolidation or merger or which shall have received such assets shall be a
corporation organized and existing under the laws of the United States of
America or a state thereof and shall assume payment of the principal of (and
premium, if any) and interest on the Senior Debt Securities and the performance
and observance of all of the covenants and conditions of the Senior Indenture to
be performed or observed by the Company, and (ii) the Company or such successor
corporation, as the case may be, shall not immediately thereafter be in default
under the Senior Indenture.

MODIFICATION AND WAIVER

  Modification and amendment of the Indenture may be effected by the Company and
the Trustee with the consent of the Holders of 66 2/3% in principal amount of
the Outstanding Senior Debt Securities of each series issued pursuant to such
indenture and affected thereby, provided that no such modification or amendment
may, without the consent of the Holder of each Outstanding Senior Debt Security
affected thereby, (a) change the Stated Maturity of the principal of, or any
installment of interest or Additional Amounts payable on, any Senior Debt
Security or any premium payable on the redemption thereof, or change the
Redemption Price; (b) reduce the principal amount of, or the interest or
Additional Amounts payable on, any Senior Debt Security or reduce the amount of
principal which could be declared due and payable prior to the Stated Maturity;
(c) change place or currency of any payment of principal or any premium,
interest or Additional Amounts payable on any Senior Debt Security; (d) impair
the right to institute suit for the enforcement of any payment on or with
respect to any Senior Debt Security; (e) reduce the percentage in principal
amount of the Outstanding Senior Debt Securities of any series, the consent of
whose Holders is required to modify or amend the Indenture; or (f) modify the
foregoing requirements or reduce the percentage of Outstanding Senior Debt
Securities necessary to waive any past default to less than a majority.  No
modification or amendment of the Subordinated Indenture or any Subsequent
Indenture for Subordinated Debt Securities may adversely affect the rights of
any holder of Senior Indebtedness without the consent of such Holder.  Except
with respect to certain fundamental provisions, the Holders of at least a
majority in principal amount of Outstanding Senior Debt Securities of any series
may, with respect to such series, waive past defaults under the Indenture and
waive compliance by the Company with certain provisions thereof.

EVENTS OF DEFAULT

  Under the Senior Indenture, the following will be Events of Default with
respect to Senior Debt Securities of any series: (a) default in the payment of
any interest or Additional Amounts payable on any Senior Debt Security of that
series when due, continued for 30 days; (b) default in the payment of any
principal or premium, if any, on any Senior Debt Security of that series when
due; (c) default in the deposit of any sinking fund payment, when due, in
respect of any Senior Debt Security of that series; (d) default in the
performance of any other covenant of the Company contained in the Indenture for
the benefit of such series or in the Senior Debt Securities of such series,

                                       15
<PAGE>
 
continued for 60 days after written notice as provided in the Senior Indenture;
(e) certain events in bankruptcy, insolvency or reorganization; and (f) any
other Event of Default provided with respect to Senior Debt Securities of that
series.  The Trustee or the Holders of 25% in principal amount of the
Outstanding Senior Debt Securities of that series may declare the principal
amount (or such lesser amount as may be provided for in the Senior Debt
Securities of that series) of all Outstanding Senior Debt Securities of that
series and the interest due thereon and Additional Amounts payable in respect
thereof, if any to be due and payable immediately if an Event of Default with
respect to Senior Debt Securities of such series shall occur and be continuing
at the time of such declaration.  At any time after a declaration of
acceleration has been made with respect to Senior Debt Securities of any series
but before a judgment or decree for payment of money due has been obtained by
the Trustee, the Holders of a majority in principal amount of the Outstanding
Senior Debt Securities of that series may rescind any declaration of
acceleration and its consequences, if all payments due (other than those due as
a result of acceleration) have been made and all Events of Default have been
remedied or waived.  Any Event of Default with respect to Senior Debt Securities
of any series may be waived by the Holders of a majority in principal amount of
all Outstanding Senior Debt Securities of that series, except in a case of
failure to pay principal or premium, if any, or interest or Additional Amounts
payable on any Senior Debt Security of that series for which payment had not
been subsequently made or in respect of a covenant or provision which cannot be
modified or amended without the consent of the Holder of each Outstanding Senior
Debt Security of such series affected.

  The Holders of a majority in principal amount of the Outstanding Senior Debt
Securities of a series may 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 Senior Debt Securities of such
series, provided that such direction shall not be in conflict with any rule of
law or the Senior Indenture.  Before proceeding to exercise any right or power
under the Senior Indenture at the direction of such Holders, the Trustee shall
be entitled to receive from such Holders reasonable security or indemnity
against the costs, expenses and liabilities which might be incurred by it in
complying with any such direction.

  The Company is required to furnish to the Trustee annually a statement as to
the fulfillment by the Company of all of its obligations under the Senior
Indenture.

    GLOBAL TELECOMMUNICATIONS PORTFOLIO MARKET INDEX TARGET-TERM SECURITIES/SM/
                              DUE OCTOBER 15, 1998
                                 ("MITTS/(R)/")

     On September 13, 1993, Merrill Lynch & Co., Inc. (the "Company") issued an
aggregate principal amount of $110,000,000 Global Telecommunications Portfolio
Market Index Target-Term Securities due October 15, 1998 (the "Securities" or
"MITTS"). As of the date of this Prospectus, $85,000,000 aggregate principal
amount of the Securities remain outstanding.  Each $10 principal amount of
Securities will be deemed a "Unit" for purposes of trading and transfer at the
Securities Depository described below. Units will be transferable by the
Securities Depository, as more fully described below, in denominations of whole
Units.

     The Securities will bear no periodic payments of interest and will mature
on October 15, 1998. At maturity, a beneficial owner of a Security will be paid
an amount based upon the change in the value of a portfolio of specified
telecommunications industry stocks of issuers organized in the United States and
abroad measured from September 2, 1993 (the "Original Portfolio Value") to the
Closing Portfolio Value, all as more fully described herein; provided, however,
that the amount payable at maturity will not be less than $9.00 for each Unit of
the Securities (the "Minimum Payment"). The Closing Portfolio Value will be
based on certain values of the specified telecommunications industry stocks
during a period prior to the maturity date of the Securities.  While at maturity
a beneficial owner of a Security may receive an amount in excess of the
principal amount of such Security if the Closing Portfolio Value exceeds the
Original Portfolio Value, there will be no payment of interest, periodic or
otherwise, prior to maturity.

     IF THE CLOSING PORTFOLIO VALUE IS LESS THAN THE ORIGINAL PORTFOLIO VALUE,
THE AMOUNT PAYABLE AT MATURITY WITH RESPECT TO A SECURITY WILL BE LESS THAN THE
PRINCIPAL AMOUNT OF SUCH SECURITY.

     For information as to the calculation of the amount that will be paid at
maturity and the calculation and the composition of the global
telecommunications industry portfolio, see "Description of Securities" and "The
Portfolio" in this Prospectus. FOR OTHER INFORMATION THAT SHOULD BE CONSIDERED
BY PROSPECTIVE INVESTORS, SEE "RISK FACTORS" BEGINNING ON PAGE 3 OF THIS
PROSPECTUS.

     Ownership of the Securities will be maintained in book-entry form by or
through the Securities Depository. Beneficial owners of the Securities will not
have the right to receive physical certificates evidencing their ownership
except under the limited circumstances described herein.

     The Securities have been listed on the New York Stock Exchange under the
Symbol "MLC".

to fixed charges . . .   1.3   1.4    1.2   1.2   1.2               1.2


  For the purpose of calculating the ratio of earnings to fixed charges,
"earnings" consists of earnings from continuing operations before income taxes
and fixed charges.  "Fixed charges" consists of interest costs, amortization of
debt expense, preferred stock dividend requirements of majority-owned
subsidiaries, and that portion of rentals estimated to be representative of the
interest factor.


                                  RISK FACTORS

Payment at Maturity

  If the Closing Portfolio Value is less than the Original Portfolio Value,
beneficial owners of the Securities will receive less than the principal amount
of such Securities at maturity, but not less than the Minimum Payment.
Beneficial owners would receive only the return of principal if the Closing
Portfolio Value should equal the Original Portfolio Value. This will be true
even though the Portfolio Value as of some interim period or periods prior to
the Calculation Period may have exceeded the Original Portfolio Value because
the Closing Portfolio Value is calculated on the basis of the average of the
value of Portfolio Securities only on the Calculation Days.

                                       3
<PAGE>
 
  Even if the principal of the Securities is fully returned, such return of
principal does not reflect any opportunity cost implied by inflation and other
factors relating to the time value of money.

  The return based on the Closing Portfolio Value relative to the Original
Portfolio Value generally will not produce the same return as if the Portfolio
Securities were purchased and held for a similar period, because, among other
reasons, any payment at maturity on the Securities based on an increase in the
value of the Portfolio will not reflect the payment of dividends on the
Portfolio Securities.

  The Senior Indenture provides that the Senior Indenture and the Securities are
governed by and construed in accordance with the laws of New York. Under present
New York law the maximum rate of interest is 25% per annum on a simple interest
basis. This limit may not apply to Securities in which $2,500,000 or more has
been invested. While the Company believes that New York law would be given
effect by a state or Federal court sitting outside of New York, state laws
frequently regulate the amount of interest that may be charged to and paid by a
borrower (including, in some cases, corporate borrowers). All payments under the
Securities (other than the return of principal) could be considered interest for
the purpose of state usury laws. The Company has covenanted for the benefit of
the Holders of the Securities, to the extent permitted by law, not to claim
voluntarily the benefits of any laws concerning usurious rates of interest
against a Holder of the Securities.

Trading

  The Securities have been listed on the New York Stock Exchange under the
Symbol "MLC". There can be no assurance as to how the Securities will trade in
the secondary market or whether such market will be liquid. It is expected that
the secondary market for the Securities will be affected by the creditworthiness
of the Company and by a number of other factors. The trading value of the
Securities is expected to depend primarily on the extent of the appreciation, if
any, of the Portfolio Value over the Original Portfolio Value. If, however,
Securities are sold prior to the maturity date at a time when the Portfolio
Value exceeds the Original Portfolio Value, the sale price may be at a discount
from the amount expected to be payable to the beneficial owner if such excess of
the Portfolio Value over the Original Portfolio Value were to prevail during the
Calculation Period. Furthermore, the price at which a beneficial owner will be
able to sell Securities prior to maturity may be at a discount, which could be
substantial, from the principal amount thereof, if, at such time, the Portfolio
Value is below, equal to or not sufficiently above the Original Portfolio Value.
A discount could also result from rising interest rates.

  The trading values of the Securities may be affected by a number of
interrelated factors, including those listed below. The relationship among these
factors is complex, including how these factors affect the value of the
principal amount of the Securities payable at maturity, if any, in excess of the
principal amount of the Securities. Accordingly, investors should be aware that
factors other than the level of the Portfolio Value are likely to affect their
trading value. The expected theoretical effect on the trading value of the
Securities of each of the factors listed below, assuming in each case that all
other factors are held constant, is as follows:

  Interest Rates. In general, if U.S. interest rates increase, the value of the
Securities is expected to decrease. If U.S. interest rates decrease, the value
of the Securities is expected to increase. Local interest rates may also affect
the economies of countries in which issuers of the respective Portfolio
Securities (or shares underlying such securities) operate, and, in turn, affect
the Portfolio Value.

  Volatility of the Portfolio Value. If the volatility of the Portfolio Value
increases, the trading value of the Securities is expected to increase. If the
volatility of the Portfolio Value decreases, the trading value of the Securities
is expected to decrease.

  Time Remaining to Maturity. The Securities may trade at a value above that
which may be inferred from the level of the Portfolio Value. This difference
will reflect a "time premium" due to expectations concerning the Portfolio Value
during the period prior to maturity of the Securities. As the time remaining to
maturity of the Securities decreases, however, this time premium is expected to
decrease, thus decreasing the trading value of the Securities.

                                       4
<PAGE>
 
  Dividend Rates. If dividend rates on the Portfolio Securities (or shares
underlying such securities) increase, the value of the Securities is expected to
decrease. Conversely, if dividend rates on the Portfolio Securities decrease,
the value of the Securities is expected to increase. Local general corporate
dividend rates may also affect the Portfolio Value and, in turn, the value of
the Securities.

Foreign Currency Exchange and Foreign Market

  The Securities are U.S. dollar-denominated securities issued by the Company, a
United States corporation. Investments in the Securities do not give the
beneficial owners any right to receive any Portfolio Security or any other
ownership right or interest in the Portfolio Securities, although the return on
the investment in the Securities is based on the Portfolio Value of the
Portfolio Securities. Certain of the Portfolio Securities (or securities
underlying DRs included in the Portfolio) have been issued by non-United States
companies, and certain of the Portfolio Securities and the underlying securities
represented by the DRs are quoted in currencies other than the U.S. dollar.
Investments in securities indexed to the value of non-United States securities
involve certain risks. Fluctuations in foreign exchange rates, future foreign
political and economic developments, and the possible imposition of exchange
controls or other foreign governmental laws or restrictions applicable to such
investments may affect the U.S. dollar value of such securities, including DRs.
Securities prices in different countries are subject to different economic,
financial, political and social factors. Rates of exchange between the dollar
and other currencies are determined by forces of supply and demand in the
foreign exchange markets. These forces are, in turn, affected by international
balance of payments and other economic and financial conditions, government
intervention, speculation and other factors. Moreover, individual foreign
economies may differ favorably or unfavorably from the U.S. economy in such
respects as growth of gross national product, rate of inflation, capital
reinvestment, resources, self-sufficiency and balance of payments position. With
respect to certain countries, there is the possibility of expropriation of
assets, confiscatory taxation, political or social instability or diplomatic
developments which could affect the value of investments in those countries.
There may be less publicly available information about a foreign company than
about a U.S. company, and foreign companies may not be subject to accounting,
auditing and financial reporting standards and requirements comparable to those
to which U.S. entities are subject. Certain foreign investments may be subject
to foreign withholding taxes which could affect the value of investment in these
countries. In addition, investment laws in certain foreign countries may limit
or restrict ownership of certain securities by foreign nationals by restricting
or eliminating voting or other rights or limiting the amount of securities that
may be so owned, and such limitations or restrictions may affect the prices of
such securities.

  Foreign financial markets, while growing in volume, may have substantially
less volume than U.S. markets, and securities of many foreign companies are less
liquid and their prices more volatile than securities of comparable domestic
companies. The foreign markets have different trading practices that may affect
the prices of securities. The foreign markets have different clearance and
settlement procedures, and in certain countries there have been times when
settlements have been unable to keep pace with the volume of securities
transactions, making it difficult to conduct such transactions. There is
generally less government supervision and regulation of exchanges, brokers and
issuers in foreign countries than there is in the U.S. In addition, the terms
and conditions of depositary facilities may result in less liquidity or lower
market values for the DRs than for the underlying stocks.

American Depositary Receipts and Global Depositary Receipts

  Certain of the Portfolio Securities are in the form of either American
Depositary Receipts ("ADRs") or Global Depositary Receipts ("GDRs", which,
together with ADRs, are hereinafter collectively referred to as "DRs"). A DR is
a negotiable receipt which is issued by a depositary, generally a bank,
representing shares (the "Underlying Shares") of a foreign issuer (the "Foreign
Issuer") that have been deposited and are held, on behalf of the holders of the
DRs, at a custodian bank in the Foreign Issuer's home country. While the market
for Underlying Shares will generally be in the country in which the Foreign
Issuer is organized, and trading in such market will generally be based on that
country's currency, DRs that are Portfolio Securities will trade in U.S.
Dollars.

                                       5
<PAGE>
 
  Although DRs are distinct securities from the Underlying Shares, the trading
characteristics and valuations of DRs will usually, but not necessarily, mirror
the characteristics and valuations of the Underlying Shares represented by the
DRs. Active trading volume and efficient pricing in the principal market in the
home country for the Underlying Shares will usually indicate similar
characteristics in respect of the DRs. In the case of certain DRs, however,
there may be inadequate familiarity with or information about the Foreign Issuer
of the Underlying Shares represented by the DR in the market in which the DR
trades to support active volume, thus resulting in pricing distortions. This is
more likely to occur when the DR is not listed on a U.S. stock exchange or
quoted on the National Market System of the National Association of Securities
Dealers Automated Quotations System ("NASDAQ"), and trades only over-the-
counter, because the Foreign Issuer would not be required to register such DRs
under the Exchange Act, as is the case with DRs so listed or quoted. In
addition, because of the size of an offering of Underlying Shares in DR form
outside the home country and/or other factors that have limited or increased the
float of certain DRs, the liquidity of such securities may be less than or
greater than that with respect to the Underlying Shares. Inasmuch as holders of
DRs may surrender the DR in order to take delivery of and trade the Underlying
Shares, a characteristic that allows investors in DRs to take advantage of price
differentials between different markets, a market for the Underlying Shares that
is not liquid will generally result in an liquid market for the DR representing
such Underlying Shares.

  The depositary bank that issues a DR generally charges a fee, based on the
price of the DR, upon issuance and cancellation of the DR. This fee would be in
addition to the brokerage commissions paid upon the acquisition or surrender of
the security. In addition, the depositary bank incurs expenses in connection
with the conversion of dividends or other cash distributions paid in local
currency into U.S. Dollars and such expenses are deducted from the amount of the
dividend or distribution paid to holders, resulting in a lower payout per
Underlying Share represented by the DR than would be the case if the Underlying
Share were held directly. Furthermore, foreign investment laws in certain
countries may restrict ownership by foreign nationals of certain classes of
Underlying Shares. Accordingly, the DR representing such class of securities may
not possess voting rights, if any, equivalent to those in respect of the
Underlying Shares. Certain tax considerations, including tax rate differentials,
arising from application of the tax laws of one nation to the nationals of
another and from certain practices in the DR market may also exist with respect
to certain DRs. In varying degrees, any or all of these factors may affect the
value of the DR compared with the value of the Underlying Shares in the local
market.

Other Considerations

  It is suggested that prospective investors who consider purchasing the
Securities should reach an investment decision only after carefully considering
the suitability of the Securities in the light of each investor's particular
circumstances.

  Investors should also consider the tax consequences of investing in the
Securities and should consult their tax advisors.


                           DESCRIPTION OF SECURITIES

General

  The Securities were issued as a series of Senior Debt Securities under the
Senior Indenture, dated as of April 1, 1983, as amended and restated, which is
more fully described below. The principal amount of each Security will equal $10
for each $10 price to the public. The Securities will mature on October 15,
1998.

  While at maturity a beneficial owner of a Security may receive an amount in
excess of the principal amount of such Security if the Closing Portfolio Value
exceeds the Original Portfolio Value, there will be no payment of interest,
periodic or otherwise, prior to maturity.  (See "Payment at Maturity", below.)

                                       6
<PAGE>
 
  The Securities are not subject to redemption by the Company or at the option
of any Holder prior to maturity. Upon the occurrence of an Event of Default with
respect to the Securities, Holders of the Securities may accelerate the maturity
of the Securities, as described under "Events of Default and Acceleration" and
"Description of Debt Securities--General--Events of Default" below.

  The Securities were issued in denominations of whole Units.

Payment at Maturity

  At maturity, a beneficial owner of a Security will be entitled to receive,
with respect to each $10 principal amount of the Security, an amount equal to
the following:

                        $10  x  Closing Portfolio Value
                                -----------------------
                                         $100

provided, however, that the amount payable at maturity will not be less than $9
for each $10 principal amount of Securities (the "Minimum Payment"). Based on
the prices of the Portfolio Securities on September 2, 1993, the Multipliers
were initially set so that the value of the Portfolio on September 2, 1993
equaled $100 (the "Original Portfolio Value").

  If the Closing Portfolio Value is equal to $90 or less, a beneficial owner of
a Security will receive the Minimum Payment of $9 for each $10 principal amount
of the Securities at maturity. If the Closing Portfolio Value is between $90 and
$100, a beneficial owner of a Security will receive between $9 and $10 for each
$10 principal amount of the Securities at maturity.

  The "Closing Portfolio Value" will be determined by MLPF&S an affiliate of the
Company, or successor thereto (the "Calculation Agent"), and will equal the sum
of the products of the Average Market Price and the applicable Multiplier for
each Portfolio Security. The "Average Market Price" of a Portfolio Security will
equal the average (mean) of the Market Prices of such Portfolio Security
determined on each of the first thirty Calculation Days with respect to such
Portfolio Security during the Calculation Period. If there are fewer than thirty
Calculation Days with respect to a Portfolio Security, then the Average Market
Price will equal the average (mean) of the Market Prices on such Calculation
Days, and if there is only one Calculation Day, then the Average Market Price
will equal the Market Price on such Calculation Day. The "Calculation Period"
means the period from and including the sixtieth scheduled NYSE Trading Day (as
defined below) prior to the maturity date to and including the fourth scheduled
NYSE Trading Day prior to the maturity date. "Calculation Day" with respect to a
Portfolio Security means any Trading Day during the Calculation Period in the
country in which such Portfolio Security is being priced on which a Market
Disruption Event has not occurred. If a Market Disruption Event occurs on all
Trading Days in such country during the Calculation Period then the fourth
scheduled NYSE Trading Day (as defined below) prior to the maturity date in such
country will be deemed a Calculation Day, notwithstanding the Market Disruption
Event; provided, however, that if such fourth scheduled NYSE Trading Day is not
a Trading Day in such country, then the immediately preceding Trading Day shall
instead be deemed a Calculation Day. Any reference to a specific day herein
shall mean such calendar day in each market in which Portfolio Securities are
priced.

  "Market Price" means for a Calculation Day the following:

    (i)  If the Portfolio Security is listed on a national securities exchange
  in the United States, is a NASDAQ National Market System ("NASDAQ NMS")
  security or is included in the OTC Bulletin Board Service ("OTC Bulletin
  Board") operated by the National Association of Securities Dealers, Inc. (the
  "NASD"), Market Price means (i) the last reported sale price, regular way, on
  such day on the principal United States securities exchange registered under
  the Securities Exchange Act of 1934 on which such Portfolio Security is listed
  or admitted to trading, or (ii) if not listed or admitted to trading on any
  such securities exchange or if such last reported sale price is not
  obtainable, the last reported sale price on the over-the-counter market as
  reported on the NASDAQ NMS or OTC Bulletin Board on such day, or (iii)

                                       7
<PAGE>
 
  if the last reported sale price is not available pursuant to (i) and (ii)
  above, the mean of the last reported bid and offer price on the over-the-
  counter market as reported on the NASDAQ NMS or OTC Bulletin Board on such day
  as determined by the Calculation Agent. If the Portfolio Security is a
  security issued by a company organized in the United States and is not listed
  on a national securities exchange in the United States, is not a NASDAQ NMS
  security or is not included in the OTC Bulletin Board operated by the NASD,
  Market Price means the average (mean) of the last available bid and offer
  prices in the United States over-the-counter market of the three dealers which
  have the highest volume of transactions in such Portfolio Security in the
  immediately preceding calendar month as determined by the Calculation Agent
  based on information that is reasonably available to it. The term "NASDAQ NMS
  security" shall include a security included in any successor to such system
  and the term "OTC Bulletin Board Service" shall include any successor service
  thereto.

    (ii)  If the Portfolio Security is a security issued by a company organized
  other than in the United States or is a DR, that, in either case, is not
  listed on a national securities exchange in the United States or is not a
  NASDAQ NMS security or included in the OTC Bulletin Board operated by the
  NASD, Market Price means the last reported sale price on such day on the
  securities exchange on which such Portfolio Security is listed or admitted to
  trading with the greatest volume of trading for the calendar month preceding
  such day as determined by the Calculation Agent, provided that if such last
  reported sale price is for a transaction which occurred more than four hours
  prior to the close of such exchange, then the Market Price shall mean the
  average (mean) of the last available bid and offer price on such exchange. If
  such Portfolio Security is not listed or admitted to trading on any such
  securities exchange or if such last reported sale price or bid and offer are
  not obtainable, the Market Price shall mean the last reported sale price on
  the over-the-counter market with the greatest volume of trading as determined
  by the Calculation Agent, provided that if such last reported sale price is
  for a transaction which occurred more than four hours prior to when trading in
  such over-the-counter market typically ends, then the Market Price shall mean
  the average (mean) of the last available bid and offer prices in such market
  of the three dealers which have the highest volume of transactions in such
  Portfolio Security in the immediately preceding calendar month as determined
  by the Calculation Agent based on information that is reasonably available to
  it. If such prices are quoted in a currency other than in U.S. Dollars, such
  prices will be translated into U.S. Dollars for purposes of calculating the
  Average Market Price using the Spot Rate on the same calendar day as the date
  of any such price. The "Spot Rate" on any date will be determined by the
  Calculation Agent and will equal the spot rate of such currency per U.S. $1.00
  on such date at approximately 3:00 p.m., New York City time, as reported on
  the information service operated by Bloomberg, L.P. ("Bloomberg") representing
  the mean of certain dealers in such currency or, if Bloomberg has not reported
  such rate by 3:30 p.m., New York City time, on such day, the offered spot rate
  of such currency per U.S. $1.00 on such date for a transaction amount in an
  amount customary for such market on such date quoted at approximately 3:30
  p.m., New York City time, by a leading bank in the foreign exchange markets as
  may be selected by the Calculation Agent.

  If the Calculation Agent is required to use the bid and offer price for a
Portfolio Security to determine the Market Price of such Portfolio Security
pursuant to the foregoing, the Calculation Agent shall not use any bid or offer
price announced by MLPF&S or any other affiliate of the Company.

  As used herein, "NYSE Trading Day" shall mean a day on which trading is
generally conducted in the over-the-counter market for equity securities in the
United States and on the New York Stock Exchange as determined by the
Calculation Agent. "Trading Day" shall mean a day on which trading is conducted
on the principal securities exchanges in the country in which such Portfolio
Security is being priced.

  "Market Disruption Event" with respect to a Portfolio Security means either of
the following events, as determined by the Calculation Agent:

    (i)  the suspension or material limitation (provided that, with respect to
  Portfolio Securities that are priced in the United States, limitations
  pursuant to New York Stock Exchange Rule 80A (or any applicable rule or
  regulation enacted or promulgated by the New York Stock Exchange, any other
  self regulatory

  organization or the Commission of similar scope as determined by the
  Calculation Agent) on trading during significant market fluctuations shall be
  considered "material" for purposes of this definition) in the trading of such
  Portfolio Security in the country in which such Portfolio Security is being
  priced for more than two hours of trading or during the period one-half hour
  prior to the time that such Portfolio Security is to be priced, or

    (ii)  the suspension or material limitation (whether by reason of movements
  in price otherwise exceeding levels permitted by the relevant exchange or
  otherwise) in option contracts related to a Portfolio Security traded on any
  exchange in the country in which such Portfolio Security is being priced for
  more than two hours of trading or during the period one-half hour prior to the
  time that such Portfolio Security is to be priced.

  For the purposes of this definition, a limitation on the hours in a trading
day and/or number of days of trading will not constitute a Market Disruption
Event if it results from an announced change in the regular business hours of
the relevant exchange.

  All determinations made by the Calculation Agent shall be at the sole
discretion of the Calculation Agent and, in the absence of manifest error, shall
be conclusive for all purposes and binding on the Company and beneficial owners
of the Securities. All percentages resulting from any calculation on the
Securities will be rounded to the nearest one hundred-thousandth of a percentage
point, with five one millionths of a percentage point rounded upwards (e.g.,
9.876545% (or .09876545) would be rounded to 9.87655% (or .0987655)), and all
dollar amounts used in or resulting from such calculation will be rounded to the
nearest cent with one-half cent being rounded upwards.

</TABLE>
(1)  Or, in the case of DRs, the Underlying Shares.

          The initial Multiplier relating to each Portfolio Security indicates
the number of such Portfolio Security, given the market price of such Portfolio
Security as of September 2, 1993, required to be included in the calculation of
the Original Portfolio Value so that each Portfolio Security represented an
equal percentage of the Original Portfolio Value as of September 2, 1993. The
price of each Portfolio Security used to calculate the initial Multiplier
relating to each such Portfolio Security was the closing price of such Portfolio
Security on September 2, 1993. The respective Multipliers will remain constant
for the term of the Securities unless adjusted for certain corporate events, as
described below.

          The Portfolio Value, for any day, will equal the sum of the products
of the most recently available Market Prices (determined as described herein)
and the applicable Multipliers for the Portfolio Securities. The Closing
Portfolio Value, however, is calculated based on averaging Market Prices for
certain days.

          The Calculation Agent currently intends to publish the Portfolio Value
once on each business day. The Calculation Agent currently calculates and
publishes values of approximately 1,100 specified portfolios. The Calculation
Agent currently provides information concerning such portfolios to the
electronic reporting services operated by Bloomberg and to newspapers and
specialized trade publications. If the Calculation Agent does publish

                                      10
<PAGE>
 
Portfolio Values, the Calculation Agent currently intends to provide such values
to similar sources described above, but there can be no assurance that such
information will ultimately be published by such sources.

Adjustments to the Multiplier and Portfolio

    The Multiplier with respect to any Portfolio Security and the Portfolio will
    be adjusted as follows:

    1. If a Portfolio Security is subject to a stock split or reverse stock
    split or similar adjustment in the case of DRs, then once such split has
    become effective, the Multiplier relating to such Portfolio Security will be
    adjusted to equal the product of the number of shares issued with respect to
    one such share of such Portfolio Security, or the number of receipts issued
    with respect to one DR if a Portfolio Security is a DR, and the prior
    multiplier.

    2. If a Portfolio Security is subject to a stock dividend (issuance of
    additional shares of the Portfolio Security) that is given equally to all
    holders of shares of the issuer of such Portfolio Security, then once the
    dividend has become effective and such Portfolio Security is trading ex-
    dividend, the Multiplier will be adjusted so that the new Multiplier shall
    equal the former Multiplier plus the product of the number of shares of such
    Portfolio Security issued with respect to one such share of Portfolio
    Security and the prior multiplier.

    3. There will be no adjustments to the Multipliers to reflect cash dividends
    or distributions paid with respect of a Portfolio Security other than for
    Extraordinary Dividends as described below. A cash dividend with respect to
    a Portfolio Security will be deemed to be an "Extraordinary Dividend" if
    such dividend exceeds the immediately preceding non-Extraordinary Dividend
    for such Portfolio Security by an amount equal to at least 10% of the Market
    Price on the Trading Day preceding the record day for the payment of such
    Extraordinary Dividend (the "ex-dividend date"). If an Extraordinary
    Dividend occurs with respect to a Portfolio Security, the Multiplier with
    respect to such Portfolio Security will be adjusted on the ex-dividend date
    with respect to such Extraordinary Dividend so that the new Multiplier will
    equal the product of (i) the then current Multiplier, and (ii) a fraction,
    the numerator of which is the sum of the Extraordinary Dividend Amount and
    the Market Price on the Trading Day preceding the ex-dividend date, and the
    denominator of which is the Market Price on the Trading Day preceding the 
    ex-dividend date. The "Extraordinary Dividend Amount" with respect to an
    Extraordinary Dividend for a Portfolio Security will equal such
    Extraordinary Dividend minus the amount of the immediately preceding non-
    Extraordinary Dividend for such Portfolio Security.

    4. If the issuer of a Portfolio Security is being liquidated or is subject
    to a proceeding under any applicable bankruptcy, insolvency or other similar
    law such Portfolio Security will continue to be included in the Portfolio so
    long as a Market Price for such Portfolio Security is available. If a Market
    Price is no longer available for a Portfolio Security for whatever reason,
    including the liquidation of the issuer of such Portfolio Security or the
    subjection of the issuer of such Portfolio Security to a proceeding under
    any applicable bankruptcy, insolvency or other similar law, then the value
    of such Portfolio Security will equal zero in connection with calculating
    Portfolio Value and Closing Portfolio Value for so long as no Market Price
    is available, and no attempt will be made to find a replacement stock or
    increase the value of the Portfolio to compensate for the deletion of such
    Portfolio Security.

    5. If the issuer of a Portfolio Security or, if a Portfolio Security is a
    DR, the Foreign Issuer of the Underlying Share, has been subject to a merger
    or consolidation and is not the surviving entity or is nationalized, then a
    value for such Portfolio Security will be determined at the time such issuer
    is merged or consolidated or nationalized and will equal the last available
    Market Price for such Portfolio Security and that value will be constant for
    the remaining term of the Securities. At such time, no adjustment will be
    made to the Multiplier of such Portfolio Security. The Company may at its
    sole discretion increase such last available Market Price to reflect
    payments or dividends of cash, securities or other consideration to holders
    of such Portfolio Security in connection with such a merger or consolidation
    which may not be reflected in such last available Market Price.

                                      11
<PAGE>
 
    6. If the issuer of a Portfolio Security issues to all of its shareholders
    equity securities of an issuer other than the issuer of the Portfolio
    Security, then such new equity securities will be added to the Portfolio as
    a new Portfolio Security. The Multiplier for such new Portfolio Security
    will equal the product of the original Multiplier with respect to the
    Portfolio Security for which the new Portfolio Security is being issued (the
    "Original Portfolio Security") and the number of shares of the new Portfolio
    Security issued with respect to one share of the Original Portfolio
    Security.
                                        
    7. If a DR is no longer listed or admitted to trading on a United States
    securities exchange registered under the Exchange Act, is no longer a NASDAQ
    NMS security or is no longer included in the OTC Bulletin Board operated by
    the NASD, then the Underlying Share represented by such DR will be deemed to
    be a new Portfolio Security. The initial Multiplier for such new Portfolio
    Security will equal the last value of the Multiplier for such DR multiplied
    by the number of shares of Underlying Shares represented by a single DR.

          No adjustments of any Multiplier of a Portfolio Security will be
required unless such adjustment would require a change of at least 1% in the
Multiplier then in effect. The Multiplier resulting from any of the adjustments
specified above will be rounded to the nearest one thousandth with five ten-
thousandths being rounded upward.

          No adjustments to the Multiplier of any Portfolio Security or to the
Portfolio will be made other than those specified above.

Hypothetical Payments
                                        
          The following table illustrates, for a range of hypothetical Closing
Portfolio Values, the amount payable at maturity for each $10 principal amount
of Securities. AN INVESTMENT IN THE PORTFOLIO SECURITIES WOULD BE SIGNIFICANTLY
DIFFERENT THAN INVESTING IN THE SECURITIES. AMONG OTHER THINGS, AN INVESTOR IN
THE PORTFOLIO SECURITIES MAY REALIZE CERTAIN DIVIDENDS THAT ARE NOT REFLECTED BY
INVESTING IN THE SECURITIES, AND CURRENCY FLUCTUATIONS MAY SIGNIFICANTLY
INCREASE OR DECREASE THE RATE OF RETURN OF THE PORTFOLIO SECURITIES VERSUS
INVESTING IN THE SECURITIES.

         The above figures are for purposes of illustration only. The actual
amount payable at maturity with respect to the Securities will depend entirely
on the actual Closing Portfolio Value.

          The investor will not receive their entire principal at maturity
should the market decline in value. The investor will only receive $9.00 for
each $10 principal amount of Securities (90% of their original investment)
should the market decline by 10% or more.

Events of Default and Acceleration

          In case an Event of Default with respect to any Securities shall have
occurred and be continuing, the amount payable to a Holder of a Security upon
any acceleration permitted by the Securities will be equal to the amount payable
calculated as though the date of early repayment were the maturity date of the
Securities. See "Description of Securities-Payment at Maturity" in this
Prospectus. If a bankruptcy proceeding is commenced in respect of the Company,
the claim of the Holder of a Security may be limited, under Section 502(b)(2) of
Title 11 of the United States Code, to the principal amount of the Security plus
an additional amount, if any, of contingent interest calculated as though the
date of the commencement of the proceeding were the maturity date of the
Securities.

          In case of default in payment at the maturity date of the Securities
(whether at their stated maturity or upon acceleration), from and after the
maturity date the Securities shall bear interest, payable upon demand of the
Holders thereof, at the rate of 6% per annum (to the extent that payment of such
interest shall be legally enforceable) on the unpaid amount due and payable on
such date in accordance with the terms of the Securities to the date payment of
such amount has been made or duly provided for.

Securities Depository

          The Securities are represented by one or more fully registered global
securities (the "Global Securities"). Each such Global Security has been
deposited with, or on behalf of, The Depository Trust Company, as Securities
Depository (the "Securities Depository"), registered in the name of the
Securities Depository or a nominee thereof. Unless and until it is exchanged in
whole or in part for Securities in definitive form, no Global Security may be
transferred except as a whole by the Securities Depository to a nominee of such
Securities Depository or by a nominee of such Securities Depository to such
Securities Depository or another nominee of such Securities Depository or by
such Securities Depository or any such nominee to a successor of such Securities
Depository or a nominee of such successor.

          The Securities Depository has advised the Company as follows: The
Securities Depository is a limited-purpose trust company organized under the
Banking Law of the State of New York, a member of the Federal Reserve System, a
"clearing corporation" within the meaning of the New York Uniform Commercial
Code, and a "clearing agency" registered pursuant to the provisions of Section
17A of the Exchange Act. The Securities Depository was created to hold
securities of its participants ("Participants") and to facilitate the clearance
and settlement of securities transactions among its Participants in such
securities through electronic book-entry changes in accounts of the
Participants, thereby eliminating the need for physical movement of securities
certificates. The Securities Depository's Participants include securities
brokers and dealers, banks, trust companies, clearing corporations, and certain
other organizations.

          The Securities Depository is owned by a number of Participants and by
the New York Stock Exchange, Inc., the American Stock Exchange, Inc. and the
NASD. Access to the Securities Depository book-entry system is also available to
others, such as banks, brokers, dealers and trust companies that clear through
or maintain a custodial relationship with a Participant, either directly or
indirectly ("Indirect Participants").

          Purchases of Securities must be made by or through Participants, which
will receive a credit on the records of the Securities Depository. The ownership
interest of each actual purchaser of each Security ("Beneficial Owner") is in
turn to be recorded on the Participants' or Indirect Participants' records.
Beneficial Owners will not receive written confirmation from the Securities
Depository of their purchase, but Beneficial Owners are expected to receive
written confirmations providing details of the transaction, as well as periodic
statements of their holdings, from the Participant or Indirect Participant
through which the Beneficial Owner entered into the transaction. Ownership of
beneficial interests in such Global Security will be shown on, and the transfer
of such ownership interests will be effected only through, records maintained by
the Securities Depository (with respect to interests of Participants) and on the
records of Participants (with respect to interests of persons held through
Participants). The laws of some states may require that certain purchasers of
securities take physical delivery of such securities in definitive form. Such
limits and such laws may impair the ability to own, transfer or pledge
beneficial interests in Global Securities.

                                      14
<PAGE>
 
  So long as the Securities Depository, or its nominee, is the registered owner
of a Global Security, the Securities Depository or its nominee, as the case may
be, will be considered the sole owner or Holder of the Securities represented by
such Global Security for all purposes under the Senior Indenture. Except as
provided below, Beneficial Owners in a Global Security will not be entitled to
have the Securities represented by such Global Securities registered in their
names, will not receive or be entitled to receive physical delivery of the
Securities in definitive form and will not be considered the owners or Holders
thereof under the Senior Indenture. Accordingly, each Person owning a beneficial
interest in a Global Security must rely on the procedures of the Securities
Depository and, if such Person is not a Participant, on the procedures of the
Participant through which such Person owns its interest, to exercise any rights
of a Holder under the Senior Indenture. The Company understands that under
existing industry practices, in the event that the Company requests any action
of Holders or that an owner of a beneficial interest in such a Global Security
desires to give or take any action which a Holder is entitled to give or take
under the Senior Indenture, the Securities Depository would authorize the
Participants holding the relevant beneficial interests to give or take such
action, and such Participants would authorize Beneficial Owners owning through
such Participants to give or take such action or would otherwise act upon the
instructions of beneficial owners. Conveyance of notices and other
communications by the Securities Depository to Participants, by Participants to
Indirect Participants, and by Participants and Indirect Participants to
Beneficial Owners will be governed by arrangements among them, subject to any
statutory or regulatory requirements as may be in effect from time to time.

          Payment of the principal of, and any additional amount payable at
maturity with respect to, Securities registered in the name of the Securities
Depository or its nominee will be made to the Securities Depository or its
nominee, as the case may be, as the Holder of the Global Securities representing
such Securities. None of the Company, the Trustee or any other agent of the
Company or agent of the Trustee will have any responsibility or liability for
any aspect of the records relating to or payments made on account of beneficial
ownership interests or for supervising or reviewing any records relating to such
beneficial ownership interests. The Company expects that the Securities
Depository, upon receipt of any payment of principal or any additional amount
payable at maturity in respect of a Global Security, will credit the accounts of
the Participants with payment in amounts proportionate to their respective
holdings in principal amount of beneficial interest in such Global Security as
shown on the records of the Securities Depository. The Company also expects that
payments by Participants to Beneficial Owners will be governed by standing
customer instructions and customary practices, as is now the case with
securities held for the accounts of customers in bearer form or registered in
"street name", and will be the responsibility of such Participants.

          If (x) the Securities Depository is at any time unwilling or unable to
continue as Securities Depository and a successor depository is not appointed by
the Company within 60 days, (y) the Company executes and delivers to the Trustee
a Company Order to the effect that the Global Securities shall be exchangeable
or (z) an Event of Default has occurred and is continuing with respect to the
Securities, the Global Securities will be exchangeable for Securities in
definitive form of like tenor and of an equal aggregate principal amount, in
denominations of $10 and integral multiples thereof. Such definitive Securities
shall be registered in such name or names as the Securities Depository shall
instruct the Trustee. It is expected that such instructions may be based upon
directions received by the Securities Depository from Participants with respect
to ownership of beneficial interests in such Global Securities.

                                 THE PORTFOLIO

General

  While the Portfolio consists of stocks (or DRs representing interests therein)
of issuers that are involved in the global telecommunications industry, the
Portfolio is not intended to provide an indication of the pattern of price
movements of common stocks of corporations involved in the global
telecommunications industry generally. Each of the United States issuers of a
Portfolio Security files certain information reports with the Commission
pursuant to the Exchange Act.  Such reports generally contain a description of
the business of the issuer, financial statements and certain other information
which may be material to potential investors in the Securities. Foreign Issuers
of

                                      15
<PAGE>
 
Underlying Shares related to DRs that are Portfolio Securities and that are
traded in the United States also file certain information reports with the
Commission pursuant to the Exchange Act, although information contained in such
reports will generally be more limited than that available with respect to a
United States issuer.  The Company makes no representation or warranty as to the
accuracy or completeness of such reports. THE INCLUSION OF A PORTFOLIO SECURITY
IN THE PORTFOLIO IS NOT A RECOMMENDATION TO BUY OR SELL SUCH PORTFOLIO SECURITY,
AND NEITHER THE COMPANY NOR ANY OF ITS AFFILIATES MAKE ANY REPRESENTATION TO ANY
PURCHASER OF SECURITIES AS TO THE PERFORMANCE OF THE PORTFOLIO.

  The Company or its affiliates may presently or from time to time engage in
business with one or more of the issuers of the Portfolio Securities or, in the
case of DRs, the Underlying Shares, including extending loans to, or making
equity investments in, such issuers or providing advisory services to such
issuers, including merger and acquisition advisory services. In the course of
such business, the Company or its affiliates may acquire non-public information
with respect to such issuers and, in addition, one or more affiliates of the
Company may publish research reports with respect to such issuers. The Company
does not make any representation to any purchaser of Securities with respect to
any matters whatsoever relating to such issuers. Any prospective purchaser of a
Security should undertake an independent investigation of the issuers of the
Portfolio Securities as in its judgment is appropriate to make an informed
decision with respect to an investment in the Securities.

Global Telecommunications Sector

  The global telecommunications industry is subject to varying degrees of
regulatory, political and economic risk which may affect the price of the stocks
of companies involved in such industry. Such risks depend on a number of factors
including the country in which a company is located. Telecommunications
companies in both developed and emerging countries are undergoing significant
change due to varying and evolving levels of governmental regulation or
deregulation and other factors. As a result, competitive pressures are intense
and the securities of such companies may be subject to rapid price volatility.
In addition, companies offering telephone services are experiencing increasing
competition from cellular telephones, and the cellular telephone industry,
because the industry has a limited operating history, faces uncertainty
concerning the future of the industry and demand for cellular telephones. All
telecommunications companies in both developed and emerging countries are
subject to the additional risk that technological innovations will make their
products and services obsolete.

  In virtually every country, certain aspects of the telecommunications industry
are subject to some government regulation. The nature and scope of such
regulation generally is subject to political forces and market considerations,
the effect of which cannot be predicted. Such regulation can have significant
effects upon the operations of a telecommunications venture. It is difficult to
predict the directions, types or effects of future telecommunications-related
regulation.

  During the 1980s and early 1990s, the global telecommunications industry
underwent structural changes. Many state-owned telephone monopolies were
completely or partially divested to the public. American Telephone & Telegraph
divested its local telephone service creating seven independent regional holding
companies in 1984 under an agreement with the U.S. Government. In addition, the
evolution of technology allowed the entrance of new competitors into the
previously exclusive domain of the traditional telephone operators including
operators of cable television systems. Companies that employ various
technologies including fibre-optic, microwave and satellite communications are
allowed to compete for traditional telephone company business in many countries.
Continued mergers, divestitures, privatizations and alliances in the global
telecommunications industry and changes in technology will affect companies
involved in such industry and the prices of their stocks.

  A potential investor should review the historical prices of the securities
underlying the Portfolio.  The historical prices of such securities should not
be taken as an indication of future performance, and no assurance can be given
that the prices of such securities will increase sufficiently to cause the
beneficial owners of the Securities to receive an amount in excess of the
Minimum Payment at the maturity of the Securities.

                                  OTHER TERMS

General

  The Securities were issued as a series of Senior Debt Securities under the
Indenture (the "Senior Indenture"), dated as of April 1, 1983, as amended and
restated, between the Company and The Chase Manhattan Bank, formerly known as
Chemical Bank (successor by merger to Manufacturers Hanover Trust Company), as
trustee (the "Trustee"). A copy of the Senior Indenture is filed as an exhibit
to the registration statements relating to the Securities. The following
summaries of certain provisions of the Senior Indenture do not purport to be
complete and are subject to, and qualified in their entirety by reference to,
all provisions of the Senior Indenture, including the definition therein of
certain terms.

  The Senior Indenture provides that series of Senior Debt Securities may from
time to time be issued thereunder, without limitation as to aggregate principal
amount, in one or more series and upon such terms as the Company may establish
pursuant to the provisions thereof.

  The Senior Indenture provides that the Senior Indenture and the Securities are
governed by and construed in accordance with the laws of the State of New York.

  The Senior Indenture provides that the Company may issue Senior Debt
Securities with terms different from those of Senior Debt Securities previously
issued, and "reopen" a previously issued series of Senior Debt Securities and
issue additional Senior Debt Securities of such series.

  The Senior Debt Securities are unsecured and rank pari passu with all other
unsecured and unsubordinated indebtedness of the Company.  However, since the
Company is a holding company, the right of the Company, and hence the right of
creditors of the Company (including the Holders of Senior Debt Securities), to
participate in any distribution of the assets of any subsidiary upon its
liquidation or reorganization or otherwise is necessarily subject to the prior
claims of creditors of the subsidiary, except to the extent that claims of the
Company itself as a creditor of the subsidiary may be recognized.  In addition,
dividends, loans and advances from certain subsidiaries, including MLPF&S, to
the Company are restricted by net capital requirements under the Exchange Act
and under rules of certain exchanges and other regulatory bodies.

Limitations Upon Liens

  The Company may not, and may not permit any Subsidiary to, create, assume,
incur or permit to exist any indebtedness for borrowed money secured by a
pledge, lien or other encumbrance (except for certain liens specifically
permitted by the Senior Indenture) on the Voting Stock owned directly or
indirectly by the Company of any Subsidiary (other than a Subsidiary which, at
the time of the incurrence of such secured indebtedness, has a net worth of less
than $3,000,000) without making effective provision whereby the Outstanding
Senior Debt Securities will be secured equally and ratably with such secured
indebtedness.

Limitation on Disposition of Voting Stock of, and Merger and Sale of Assets by,
MLPF&S

  The Indenture provides that the Company may not sell, transfer or otherwise
dispose of any Voting Stock of MLPF&S or permit MLPF&S to issue, sell or
otherwise dispose of any of its Voting Stock, unless, after giving effect to any
such transaction, MLPF&S remains a Controlled Subsidiary (defined in the Senior
Indenture to mean a corporation more than 80% of the outstanding shares of
Voting Stock of which are owned directly or indirectly by the Company).  In
addition, the Company may not permit MLPF&S to (i) merge or consolidate, unless
the surviving company is a Controlled Subsidiary or (ii) convey or transfer its
properties and assets substantially as an entirety, except to one or more
Controlled Subsidiaries.

                                      17
<PAGE>
 
Merger and Consolidation

  The Indenture provides that the Company may consolidate or merge with or into
any other corporation, and the Company may sell, lease or convey all or
substantially all of its assets to any corporation, provided that (i) the
corporation (if other than the Company) formed by or resulting from any such
consolidation or merger or which shall have received such assets shall be a
corporation organized and existing under the laws of the United States of
America or a state thereof and shall assume payment of the principal of (and
premium, if any) and interest on the Senior Debt Securities and the performance
and observance of all of the covenants and conditions of the Senior Indenture to
be performed or observed by the Company, and (ii) the Company or such successor
corporation, as the case may be, shall not immediately thereafter be in default
under the Senior Indenture.

Modification and Waiver

  Modification and amendment of the Indenture may be effected by the Company and
the Trustee with the consent of the Holders of 66 2/3% in principal amount of
the Outstanding Senior Debt Securities of each series issued pursuant to such
indenture and affected thereby, provided that no such modification or amendment
may, without the consent of the Holder of each Outstanding Senior Debt Security
affected thereby, (a) change the Stated Maturity of the principal of, or any
installment of interest or Additional Amounts payable on, any Senior Debt
Security or any premium payable on the redemption thereof, or change the
Redemption Price; (b) reduce the principal amount of, or the interest or
Additional Amounts payable on, any Senior Debt Security or reduce the amount of
principal which could be declared due and payable prior to the Stated Maturity;
(c) change place or currency of any payment of principal or any premium,
interest or Additional Amounts payable on any Senior Debt Security; (d) impair
the right to institute suit for the enforcement of any payment on or with
respect to any Senior Debt Security; (e) reduce the percentage in principal
amount of the Outstanding Senior Debt Securities of any series, the consent of
whose Holders is required to modify or amend the Indenture; or (f) modify the
foregoing requirements or reduce the percentage of Outstanding Senior Debt
Securities necessary to waive any past default to less than a majority.  No
modification or amendment of the Subordinated Indenture or any Subsequent
Indenture for Subordinated Debt Securities may adversely affect the rights of
any holder of Senior Indebtedness without the consent of such Holder.  Except
with respect to certain fundamental provisions, the Holders of at least a
majority in principal amount of Outstanding Senior Debt Securities of any series
may, with respect to such series, waive past defaults under the Indenture and
waive compliance by the Company with certain provisions thereof.

Events of Default

  Under the Senior Indenture, the following will be Events of Default with
respect to Senior Debt Securities of any series: (a) default in the payment of
any interest or Additional Amounts payable on any Senior Debt Security of that
series when due, continued for 30 days; (b) default in the payment of any
principal or premium, if any, on any Senior Debt Security of that series when
due; (c) default in the deposit of any sinking fund payment, when due, in
respect of any Senior Debt Security of that series; (d) default in the
performance of any other covenant of the Company contained in the Indenture for
the benefit of such series or in the Senior Debt Securities of such series,
continued for 60 days after written notice as provided in the Senior Indenture;
(e) certain events in bankruptcy, insolvency or reorganization; and (f) any
other Event of Default provided with respect to Senior Debt Securities of that
series.  The Trustee or the Holders of 25% in principal amount of the
Outstanding Senior Debt Securities of that series may declare the principal
amount (or such lesser amount as may be provided for in the Senior Debt
Securities of that series) of all Outstanding Senior Debt Securities of that
series and the interest due thereon and Additional Amounts payable in respect
thereof, if any to be due and payable immediately if an Event of Default with
respect to Senior Debt Securities of such series shall occur and be continuing
at the time of such declaration.  At any time after a declaration of
acceleration has been made with respect to Senior Debt Securities of any series
but before a judgment or decree for payment of money due has been obtained by
the Trustee, the Holders of a majority in principal amount of the Outstanding
Senior Debt Securities of that series may rescind any declaration of
acceleration and its consequences, if all payments due (other than those due as
a result of acceleration) have been made and all Events of Default have been
remedied or waived.  Any Event of Default with respect to Senior Debt Securities
of any series may be waived by the Holders of a majority in principal amount of
all Outstanding Senior

                                      18
<PAGE>
 
Debt Securities of that series, except in a case of failure to pay principal or
premium, if any, or interest or Additional Amounts payable on any Senior Debt
Security of that series for which payment had not been subsequently made or in
respect of a covenant or provision which cannot be modified or amended without
the consent of the Holder of each Outstanding Senior Debt Security of such
series affected.

  The Holders of a majority in principal amount of the Outstanding Senior Debt
Securities of a series may 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 Senior Debt Securities of such
series, provided that such direction shall not be in conflict with any rule of
law or the Senior Indenture.  Before proceeding to exercise any right or power
under the Senior Indenture at the direction of such Holders, the Trustee shall
be entitled to receive from such Holders reasonable security or indemnity
against the costs, expenses and liabilities which might be incurred by it in
complying with any such direction.

  The Company is required to furnish to the Trustee annually a statement as to
the fulfillment by the Company of all of its obligations under the Senior
Indenture.

                     RUSSELL 2000/(R)/ INDEX* CALL WARRANTS
                           EXPIRING NOVEMBER 17, 1998
                         -----------------------------

  On November 27, 1995, Merrill Lynch & Co., Inc. (the "Company") issued
1,350,000 Russell 2000 Index Call Warrants Expiring November 17, 1998 (the
"Warrants").  Each Warrant will entitle the beneficial owner thereof to receive
from the Company upon exercise (including automatic exercise) an amount in U.S.
dollars computed by reference to increases in the Russell 2000 Index (the
"Index"). Such amount (the "Cash Settlement Value") will equal the product, if
positive, of $15 multiplied by the Percentage Change in the Index. The
"Percentage Change" will equal (i) the Index Spot Price minus the Index Strike
Price, divided by (ii) the Index Strike Price. The Cash Settlement Value cannot
be less than zero. The Index Strike Price equals 302.22 and the Index Spot Price
will be determined upon exercise as more fully described herein.

  The Warrants will be exercisable at the option of the beneficial owner from
the date of the initial delivery of the Warrants until 1:00 p.m., New York City
time, on the fourth scheduled Index Calculation Day (as defined herein)
immediately preceding the earlier of their expiration on November 17, 1998 (the
"Expiration Date"), cancellation, or the date of their earlier expiration upon
delisting from, or permanent suspension of trading on, the American Stock
Exchange (the "AMEX") unless the Warrants are simultaneously accepted for
trading pursuant to the rules of another Self-Regulatory Organization (as
defined herein). Any Warrant not exercised at or before 1:00 p.m., New York City
time, on the fourth scheduled Index Calculation Day immediately preceding the
Expiration Date or the date of their earlier expiration will be deemed
automatically exercised on the first scheduled Index Calculation Day immediately
preceding the Expiration Date or, in the case of early expiration, on the first
scheduled Index Calculation Day immediately preceding the Early Expiration Date
(as defined herein). A beneficial owner may exercise no fewer than 100 Warrants
at any one time, except in the case of automatic exercise. The valuation of and
payment for any exercised Warrant (including automatic exercise) may be
postponed as a result of the occurrence of certain events. See "Description of
the Warrants". The Warrants will be in book-entry form and, accordingly, no
beneficial owner of Warrants will be entitled to receive a certificate
representing such Warrants.

  THE WARRANTS INVOLVE A HIGH DEGREE OF RISK, INCLUDING THE RISK OF EXPIRING
WORTHLESS. INVESTORS THEREFORE SHOULD BE PREPARED TO SUSTAIN A TOTAL LOSS OF THE
PURCHASE PRICE OF THEIR WARRANTS, AND ARE ADVISED TO CAREFULLY CONSIDER THE
INFORMATION UNDER "RISK FACTORS" BEGINNING ON PAGE 4 OF THIS PROSPECTUS,

debt expense, preferred stock dividend requirements of majority-owned
subsidiaries, and that portion of rentals estimated to be representative of the
interest factor.

             CERTAIN IMPORTANT INFORMATION CONCERNING THE WARRANTS

  A beneficial owner will receive a cash payment upon exercise only if the
Warrants have a Cash Settlement Value in excess of zero on the relevant
Valuation Date. The Warrants will be "in-the-money" (i.e., their Cash Settlement
Value will exceed zero) on the relevant Valuation Date only if, as of such date,
the value of the Index increases from the date of this Prospectus so that the
Index Spot Price is above the Index Strike Price. An increase in the level of
the Index from the date of this Prospectus will result in a greater Cash
Settlement Value for the Warrants, and a decrease in the level of the Index from
the date of this Prospectus will result in a lesser or zero Cash Settlement
Value for the Warrants. If a Warrant is not exercised prior to its expiration
and, on the Valuation Date with respect to its expiration, the value of the
Index is less than or equal to the Index Strike Price, the Warrant will expire
worthless and the beneficial owner will have sustained a total loss of the
purchase price of such Warrant. Investors therefore should be prepared to
sustain a total loss of the purchase price of their Warrants.


                                  RISK FACTORS

  THE WARRANTS INVOLVE A HIGH DEGREE OF RISK, INCLUDING THE RISK OF EXPIRING
WORTHLESS. INVESTORS THEREFORE SHOULD BE PREPARED TO SUSTAIN A TOTAL LOSS OF THE
PURCHASE PRICE OF THEIR WARRANTS. IT IS SUGGESTED THAT INVESTORS CONSIDERING
PURCHASING THE WARRANTS BE EXPERIENCED WITH RESPECT TO OPTIONS AND OPTION
TRANSACTIONS AND UNDERSTAND THE RISKS OF STOCK INDEX TRANSACTIONS AND REACH AN
INVESTMENT DECISION ONLY AFTER CAREFULLY CONSIDERING ALL OF THE RISK FACTORS SET
FORTH IN THIS SECTION OF THIS PROSPECTUS, THE SUITABILITY OF THE WARRANTS IN
LIGHT OF THEIR PARTICULAR CIRCUMSTANCES AND ALL THE OTHER INFORMATION SET FORTH
IN THIS PROSPECTUS.

  Underlying Stocks. The underlying stocks that constitute the Index (the
"Underlying Stocks") have been issued by corporations domiciled in the U.S. and
its territories and traded on the NYSE, AMEX or in the over-the-counter market.
If a Successor Index is substituted for the Index, such Successor Index would
also be based upon stocks issued by corporations domiciled in the U.S. and its
territories and traded on the NYSE, AMEX or in the over-the-counter market.
Investments in securities indexed to the value of small capitalization companies
involve certain risks. In general, the stocks comprising the Index have smaller
market capitalizations, less trading liquidity and greater price volatility than
stocks in other larger capitalization indexes which are designed to measure the
broad movement of the U.S. stock market. These factors may adversely affect the
value of the Index and the Warrants.

  The Underlying Stocks are traded on the NYSE, AMEX and in the over-the-counter
market. Certain of these markets have adopted measures intended to prevent
extreme short-term price fluctuations resulting from order imbalances. Investors
should also be aware that certain of these markets may suspend the trading of
individual stocks in certain limited and extraordinary circumstances including,
for example, unusual trading activity in that stock. As a result, variations in
the Index may be limited by price limitations on, or by suspension of trading
in, individual stocks which comprise the Index which may, in turn, adversely
affect the value of the Warrants or result in a Market Disruption Event. See
"Description of the Warrants--Extraordinary Events and Market Disruption
Events".

  Exercise of Warrants. A beneficial owner may incur transaction costs in
connection with any exercise of Warrants. To the extent Warrants are exercised,
including Warrants exercised by the Underwriter or any of its affiliates, the
number of Warrants outstanding will decrease, which may result in a decrease in
the liquidity of the Warrants.

  Certain Factors Affecting the Value of the Warrants. The Cash Settlement Value
of the Warrants at any time prior to expiration is typically expected to be less
than the Warrants' trading value at that time. The difference between the
trading value and the Cash Settlement Value will reflect a number of factors,
including a "time value" for the Warrants. The "time value" of the Warrants will
depend upon the length of the period remaining to expiration, among other
factors. The expiration date of the Warrants will be accelerated should the
Warrants be delisted or should their trading on the AMEX be suspended
permanently unless the Warrants simultaneously are accepted for trading pursuant
to the rules of another self-regulatory organization (a "Self-Regulatory
Organization"). Any such acceleration would result in the total loss of any
otherwise remaining "time value", and could occur when the Warrants are out-of-
the-money, thus resulting in total loss of the purchase price of the Warrants.
See "Description of the Warrants--Delisting of the Warrants". Before exercising
or selling Warrants, beneficial owners should

                                       4
<PAGE>
 
carefully consider the trading value of the Warrants, the value of the Index at
the time, the time remaining to expiration and the probable range of Cash
Settlement Values and any related transaction costs.

  There can be no assurance as to how the Warrants will trade in the secondary
market or whether such market will be liquid. The trading value of a Warrant is
expected to be dependent upon a number of complex interrelated factors,
including those listed below. The expected theoretical effect on the trading
value of a Warrant of each of the factors listed below, assuming in each case
that all other factors are held constant, is as follows:

  (1) The Index. If the value of the Index increases, the trading value of a
Warrant is expected to increase. If the value of the Index decreases, the
trading value of a Warrant is expected to decrease. It is possible that the
trading value of a Warrant may decline even if there is an increase in the value
of the Index.

  (2) The volatility of the Index. If the volatility of the Index increases, the
trading value of a Warrant is expected to increase. If such volatility
decreases, the trading value of a Warrant is expected to decrease.

  (3) The time remaining to the Expiration Date of the Warrants. An index
warrant is a "wasting asset", meaning that as the time remaining to the
Expiration Date decreases, the trading value of a Warrant is expected to
decrease.

  (4) Interest rates in the United States. In general, if U.S. interest rates
increase, the trading value of the Warrants is expected to increase. If U.S.
interest rates decrease, the trading value of the Warrants is expected to
decrease.

  (5) Dividend rates. If dividend rates on the common stocks underlying the
Index increase, the trading value of a Warrant is expected to decrease. If
dividend rates on the common stocks underlying the Index decrease, the trading
value of a Warrant is expected to increase. Changes in the dividend rates on the
common stocks underlying the Index may affect the value of the Index and
therefore the value of the Warrants as described above.

As noted above, these hypothetical scenarios are based on the assumption that
all other factors are held constant. In reality, it is unlikely that only one
factor would change in isolation, because changes in one factor usually cause,
or result from, changes in others.

  Minimum Exercise Amount. Except for cases of automatic exercise, a beneficial
owner must tender at least 100 Warrants at any one time in order to exercise
Warrants. Thus, except in cases of automatic exercise, beneficial owners with
fewer than 100 Warrants will need either to sell their Warrants or to purchase
additional Warrants, incurring transaction costs in either case, in order to
realize proceeds from their investment. At any time that a beneficial owner must
purchase additional Warrants in order to have the minimum number of Warrants
necessary to elect to exercise, such beneficial owner will be subject to the
secondary market for Warrants at the time of any such purchase, including the
risk that there may be a limited number of Warrants available in such market at
such time and the other factors affecting the secondary market discussed above.
Furthermore, such beneficial owners incur the risk that there may be differences
between the trading value of the Warrants and the Cash Settlement Value of such
Warrants.

  Maximum Exercise Amount. All exercises of Warrants (other than on automatic
exercise) are subject, at the Company's option, to the limitation that not more
than 20% of the Warrants originally issued may be exercised on any Exercise Date
and not more than 10% of the Warrants originally issued may be exercised by or
on behalf of any beneficial owner, either individually or in concert with any
other beneficial owner, on any Exercise Date. If any New York Business Day would
otherwise, under the terms of the Warrant Agreement, be the Exercise Date in
respect to more than 20% of the Warrants originally issued, then at the
Company's election 20% of the Warrants originally issued (provided, however,
that no more than 10% of the Warrants originally issued shall be exercised for
the account of any beneficial owner) shall be exercised on such Exercise Date
(selected by the Warrant Agent on a pro rata basis, but if, as a result of such
pro rata selection, any beneficial owner of Warrants would be deemed to have
exercised less than 100 Warrants, as the case may be, the Warrant Agent shall
first select an additional amount of such beneficial owner's Warrants so that no
beneficial owner shall be deemed to have exercised fewer than 100 Warrants), and
the remainder of such Warrants (the "Remaining Warrants") shall be deemed
exercised on the following New York Business Day subject to successive
applications of this provision; provided that any Remaining Warrants which were
exercised on a prior Exercise Date shall be deemed exercised before any other
Warrants exercised on a subsequent Exercise Date. As a result of any such
postponed exercise, beneficial owners will receive a Cash Settlement Value
determined as of a date later than the otherwise applicable Valuation Date. In
any such case, as

                                       5
<PAGE>
 
a result of any such postponement, the Cash Settlement Value actually received
by beneficial owners may be lower than the otherwise applicable Cash Settlement
Value if the Valuation Date of the Warrants had not been postponed.

  Time Lag After Exercise Instructions Given. In the case of any exercise of
Warrants, there will be a time lag between the time a beneficial owner gives
instructions to exercise and the time the Index Spot Price relating to such
exercise is determined. Therefore, a beneficial owner will not be able to
determine, at the time of exercise of a Warrant, the Index Spot Price that will
be used in calculating the Cash Settlement Value of such Warrant (and will thus
be unable to determine such Cash Settlement Value). The delay will, at a
minimum, amount to several hours and could be much longer (e.g., an exercise
notice received by the Warrant Agent after 1:00 p.m. Friday would generally
result in the Index Spot Price being determined the following Monday). Any
downward movement in the level of the Index between the time a beneficial owner
of a Warrant exercises a Warrant and the time the Index Spot Price for such
exercise is determined will result in such beneficial owner receiving a Cash
Settlement Value that is less than the Cash Settlement Value anticipated by such
beneficial owner based on the level of the Index most recently reported prior to
exercise. A beneficial owner that has not exercised a Warrant prior to the
fourth scheduled Index Calculation Day preceding the Expiration Date will,
pursuant to the provision for automatic exercise, have the Index Spot Price with
respect to such Warrant determined on the deemed exercise day, if such deemed
exercise date is an Index Calculation Day, or on the immediately succeeding
Index Calculation Day, if such deemed exercise date is not an Index Calculation
Day. The value of the Index may change significantly during any such period, and
such movements could adversely affect the Cash Settlement Value of the Warrants
being exercised.

  Further delay may occur if a Market Disruption Event or Extraordinary Event
has occurred, in which case the Cash Settlement Value in respect of exercised
Warrants will be calculated as of the next succeeding Index Calculation Day on
which there is no Market Disruption Event or Extraordinary Event. If the
Calculation Agent determines that on a Valuation Date a Market Disruption Event
or Extraordinary Event has occurred, the Valuation Date shall be postponed to
the first succeeding Index Calculation Day on which no Market Disruption Event
or Extraordinary Event occurs; provided that, if the Valuation Date has not
occurred on or prior to the fifth Index Business Day following an Exercise Date
because of Market Disruption Events, such fifth Index Business Day shall be the
Valuation Date regardless of whether a Market Disruption Event has occurred on
such day; provided further, however, that if an Extraordinary Event has occurred
and is continuing, and if the Extraordinary Event is expected by the Company to
continue, the Company may immediately cancel the Warrants as described below
under "Description of the Warrants--Extraordinary Events and Market Disruption
Events". During any period of delay due to a Market Disruption Event or
Extraordinary Event, the value of the Index may change significantly, and such
change may adversely affect the amount paid on any Warrants exercised during
such period.

  Automatic Exercise of the Warrants upon Delisting. In the event that the
Warrants are delisted from, or permanently suspended from trading on, the AMEX
and the Warrants are not simultaneously accepted for trading pursuant to the
rules of another Self-Regulatory Organization that are filed with the Commission
under the Exchange Act, such Warrants not previously exercised will expire on
the date such delisting or trading suspension becomes effective and will be
deemed automatically exercised on the first scheduled Index Calculation Day
immediately preceding the date of such early expiration. At the applicable
Valuation Date with respect to such automatic exercise, the Warrants may be out-
of-the-money so that the Cash Settlement Value would equal zero.

  Warrants Not Standardized Options Issued by the Options Clearing Corporation.
The Warrants are not standardized stock index options of the type issued by the
Options Clearing Corporation (the "OCC"), a clearing agency regulated by the
Commission. For example, unlike purchasers of OCC standardized options who have
the credit benefits of guarantees and margin and collateral deposits by OCC
clearing members to protect the OCC from a clearing member's failure, purchasers
of Warrants must look solely to the Company for performance of its obligations
to pay the Cash Settlement Value or Alternative Settlement Amount on the
exercise of Warrants. Further, the market for the Warrants is not expected to be
generally as liquid as the market for OCC standardized options. The OCC does
issue standardized stock index options in which payments, if any, are determined
based on changes in the Index.

  The Warrants are unsecured contractual obligations of the Company and rank on
a parity with the Company's other unsecured contractual obligations and with the
Company's unsecured and unsubordinated debt. However, given that the Company is
a holding company, the right of the Company, and hence the right of creditors of
the Company (including beneficial owners of the Warrants), to participate in any
distribution of the assets of any subsidiary upon its liquidation or
reorganization or otherwise is necessarily subject to the prior claims of
creditors of the subsidiary,

                                       6
<PAGE>
 
except to the extent that claims of the Company itself as a creditor of the
subsidiary may be recognized. In addition, dividends, loans and advances from
certain subsidiaries, including MLPF&S, to the Company are restricted by net
capital requirements under the Exchange Act, and under rules of certain
exchanges and other regulatory bodies.

  Relationship to the Index. Options and warrants provide opportunities for
investment and pose risks to investors as a result of fluctuations in the value
of the underlying investment. In general, certain of the risks associated with
the Warrants are similar to those generally applicable to other options or
warrants of private corporate issuers. However, unlike options or warrants on
equities or debt securities, which are traded primarily on the basis of the
value of a single underlying security, the trading value of a Warrant is likely
to reflect primarily the extent of the appreciation, if any, of the Index.

  The purchaser of a Warrant may lose his entire investment. This risk reflects
the nature of a Warrant as an asset which tends to decline in value over time
and which may, depending on the relative value of the Index, be worthless when
it expires. Assuming all other factors are held constant, the more a Warrant is
out-of-the-money and the shorter its remaining term to expiration, the greater
the risk that a purchaser of the Warrant will lose all of his investment. This
means that the purchaser of a Warrant who does not sell it in the secondary
market or exercise it prior to expiration will necessarily lose his entire
investment in the Warrant if it expires when the Index Spot Price is less than
or equal to the Index Strike Price.

  The fact that Warrants may become valueless upon expiration means that, in
order to recover and realize a return upon his investment, a purchaser of a
Warrant must generally be correct about the direction, timing and magnitude of
anticipated changes in the value of the Index. If the value of the Index does
not increase to an extent sufficient to cover an investor's cost of a Warrant
(i.e., the purchase price plus transaction costs, if any) before the Warrant
expires, the investor will lose all or a part of his investment in the Warrant
upon expiration.

  Suitability. The AMEX requires that Warrants be sold only to investors with
options-approved accounts and that its members and member organizations and
registered employees thereof make certain suitability determinations before
recommending transactions in Warrants. It is suggested that investors
considering purchasing Warrants be experienced with respect to options and
option transactions and understand the risks of stock index transactions and
reach an investment decision only after carefully considering, with their
advisers, the suitability of the Warrants in light of their particular
circumstances. Warrants are not suitable for persons solely dependent upon a
fixed income, for individual retirement plan accounts or for accounts under the
Uniform Gift to Minors Act. INVESTORS SHOULD BE PREPARED TO SUSTAIN A TOTAL LOSS
OF THE PURCHASE PRICE OF THEIR WARRANTS.

  Successor Index. In the event that the Index is not published by Frank Russell
Company ("FRC") but is published by another party acceptable to the Calculation
Agent, then the Index Spot Price for any date thereafter will be determined
based on the closing level of the Index as published by such third party. If FRC
or any third party discontinues publication of the Index and publishes a
successor or substitute index that the Calculation Agent determines, in its sole
discretion, to be comparable to the Index (any such index being a "Successor
Index"), then the Index Spot Price for any date thereafter will be determined by
the Calculation Agent on behalf of the Company based on the Successor Index on
such date. If FRC or any third party makes a material change in the formula for,
or the method of calculating, the Index or any Successor Index, the Calculation
Agent shall make such calculations as may be required to determine the
applicable Cash Settlement Value using the formula and method of calculating the
Index or any Successor Index as in effect prior to such change or modification.
If FRC and/or any third party discontinues publication of the Index and/or any
Successor Index, the Calculation Agent will determine the applicable Cash
Settlement Value based on the formula and method used in calculating the Index
or any Successor Index as in effect on the date the Index or such Successor
Index was last published.

  The Company and Its Affiliates. The Underwriter and its affiliates may from
time to time engage in transactions involving the Underlying Stocks for their
proprietary accounts and for other accounts under their management, which may
influence the value of such Underlying Stocks and therefore the value of the
Warrants. The Underwriter and its affiliates will also be the writers of the
hedge of the Company's obligations under the Warrants and will be obligated to
pay to the Company upon exercise of Warrants an amount equal to the value of the
exercised Warrants.  Accordingly, under certain circumstances, conflicts of
interest may arise between the Underwriter's responsibilities as Calculation
Agent with respect to the Warrants and its obligations under its hedge and its
status as a subsidiary of the Company. Under certain circumstances, the duties
of the Underwriter as Calculation Agent in determining the existence of
Extraordinary Events and Market Disruption Events could conflict with the
interests of the Underwriter

                                       7

as an affiliate of the issuer of the Warrants, Merrill Lynch & Co., Inc., and
with the interests of the beneficial owners of the Warrants.

                          DESCRIPTION OF THE WARRANTS

GENERAL

  An aggregate of 1,350,000 Russell 2000 Index Call Warrants, Expiring November
17, 1998 (the "Warrants") were issued. The Warrants were issued under a Warrant
Agreement (the "Warrant Agreement"), dated November 27, 1995, between the
Company and Citibank, N.A., as Warrant Agent (the "Warrant Agent"). The
following statements with respect to the Warrants are summaries of the detailed
provisions of the Warrant Agreement, the form of which is filed as an exhibit to
the Registration Statement relating to the Warrants. Wherever particular
provisions of the Warrant Agreement or terms defined therein are referred to,
such provisions or definitions are incorporated by reference as a part of the
statements made, and the statements are qualified in their entirety by such
reference.

  A Warrant will not require, or entitle, a beneficial owner to sell or purchase
any shares of any stock underlying the Index or any Successor Index or any other
securities to or from the Company. The Company will make only a U.S. dollar cash
settlement, if any, upon exercise of a Warrant. A beneficial owner will not
receive any interest on any Cash Settlement Value or Alternative Settlement
Amount and the Warrants will not entitle the beneficial owners thereof to any of
the rights of holders of any underlying stock or other securities.

  "Holder" means the person in whose name a certificate representing a Warrant
is registered in the records of the Warrant Agent, which, so long as the
Warrants are held in book-entry form, will be CEDE & Co.

  The Warrants are exercisable commencing on the date of initial delivery of the
Warrants, as set forth under "Exercise of Warrants". The Warrants will expire on
November 17, 1998 (the "Expiration Date") or may expire on an earlier date as
described under "Automatic Exercise". Warrants not exercised at or prior to 1:00
p.m., New York City time, on the fourth scheduled Index Calculation Day
immediately preceding the Expiration Date or earlier expiration will be deemed
automatically exercised on the first scheduled Index Calculation Day preceding
the Expiration Date or, in the case of early expiration, on the first scheduled
Index Calculation Day immediately preceding the Early Expiration Date. Warrants
cancelled upon the occurrence and continuation of an Extraordinary Event shall
be exercised as described below under "Extraordinary Events and Market
Disruption Events". The term "New York Business Day", as used herein, means any
day other than a Saturday or a Sunday or a day on which commercial banks in The
City of New York are required or authorized by law or executive order to be
closed, and "Index Business Day" means any day on which the NYSE is scheduled to
be open for trading.

  The Warrants are unsecured contractual obligations of the Company and rank on
a parity with the Company's other unsecured contractual obligations and with the
Company's unsecured and unsubordinated debt. However, given that the Company is
a holding company, the right of the Company, and hence the right of creditors of
the Company (including beneficial owners of the Warrants), to participate in any
distribution of the assets of any subsidiary upon its liquidation or
reorganization or otherwise is necessarily subject to the prior claims of
creditors of the subsidiary, except to the extent that claims of the Company
itself as a creditor of the subsidiary may be recognized. In addition,
dividends, loans and advances from certain subsidiaries, including MLPF&S, to
the Company are restricted by net capital requirements under the Exchange, and
under rules of certain exchanges and other regulatory bodies.


CASH SETTLEMENT VALUE

  The Cash Settlement Value of an exercised Warrant is an amount stated in U.S.
dollars that results from the following formula:

                          Percentage Change   X   $15

  The "Percentage Change" will equal the following amount:

                      Index Spot Price-Index Strike Price
                      -----------------------------------
                               Index Strike Price

                                       8
<PAGE>
 
    The "Index Spot Price" relating to any Exercise Date will be determined by
MLPF&S (the "Calculation Agent") on the Valuation Date relating to such Exercise
Date.

  The "Index Strike Price" equals 302.22.

  The "Index" means the Russell 2000 Index, as presently calculated and
disseminated by FRC, except as otherwise provided herein. See "Description of
the Warrants--The Index".

  The Cash Settlement Value will be rounded, if necessary, to the nearest cent
(with one-half cent being rounded upwards).

  Set forth below are illustrations of the Cash Settlement Values for Warrants
at exercise based upon various hypothetical percentage changes in the value of
the Index. The Index Percentage Change on Valuation Date column indicates the
percentage increase or decrease in the value of the Index Spot Price as compared
to the Index Strike Price at the time of exercise. The actual Cash Settlement
Value of a Warrant will depend entirely on the actual Index Percentage Change on
the applicable Valuation Date relating to the Exercise Date. The illustrative
Cash Settlement Values in the table do not reflect any "time value" for a
Warrant, which may be reflected in trading value, and are not necessarily
indicative of potential profit or loss, which are also affected by purchase
price and transaction costs.

BOOK-ENTRY PROCEDURES AND SETTLEMENT

  The Warrants are represented by one registered global Warrant (a "Global
Warrant"). The Global Warrant will be deposited with, or on behalf of, The
Depository Trust Company, as Securities Depository (the "Securities Depository"
or "DTC"), and registered in the name of the Securities Depository or a nominee
thereof. Unless and until the Global Warrant is exchanged in whole or in part
for Warrants in definitive form in the limited circumstances described below,
such Global Warrant may not be transferred except as a whole by the Securities
Depository to a nominee of such Securities Depository or by a nominee of such
Securities Depository to such

                                       9
<PAGE>
 
Securities Depository or another nominee of such Securities Depository or by
such Securities Depository or any such nominee to a successor of such Securities
Depository or a nominee of such successor. Morgan Guaranty Trust Company of New
York, Brussels office, as operator for the Euroclear System ("Euroclear") and
Cedel Bank, societe anonyme ("Cedel") will hold interests in the Global Warrant
on behalf of their participants through the facilities of DTC.

  The Securities Depository has advised the Company as follows: The Securities
Depository is a limited-purpose trust company organized under the Banking Laws
of the State of New York, a member of the Federal Reserve System, a "clearing
corporation" within the meaning of the New York Uniform Commercial Code, and a
"clearing agency" registered pursuant to the provisions of Section 17A of the
Exchange Act. The Securities Depository was created to hold securities of its
participants and to facilitate the clearance and settlement of securities
transactions among its participants in such securities through electronic book-
entry changes in accounts of the participants, thereby eliminating the need for
physical movement of securities certificates. The Securities Depository's
participants include securities brokers and dealers (including the Underwriter),
banks, trust companies, clearing corporations, and certain other organizations,
some of whom (and/or their representatives) own the Securities Depository.
Access to the Securities Depository book-entry system is also available to
others, such as banks, brokers, dealers and trust companies that clear through
or maintain a custodial relationship with a participant, either directly or
indirectly. Persons who are not participants may beneficially own securities
held by the Securities Depository only through participants.

  Ownership of beneficial interests in the Warrants will be limited to persons
that have accounts with the Securities Depository ("Agent Members") or persons
that may hold interests through Agent Members. The Securities Depository has
advised the Company that upon the issuance of the Global Warrant representing
the Warrants, the Securities Depository will credit, on its book-entry
registration and transfer system, the Agent Members' accounts with the
respective number of Warrants represented by such Global Warrant. Ownership of
beneficial interests in the Global Warrant will be shown on, and the transfer of
such ownership interests will be effected only through, records maintained by
the Securities Depository (with respect to interests of Agent Members) and on
the records of Agent Members (with respect to interests of persons held through
Agent Members). The laws of some states may require that certain purchasers of
securities take physical delivery of such securities in definitive form. Such
limits and such laws may impair the ability to own, transfer or pledge
beneficial interests in the Global Warrant.

  So long as the Securities Depository, or its nominee, is the registered owner
of the Global Warrant, the Securities Depository or its nominee, as the case may
be, will be considered the sole owner or Holder of the Warrants represented by
the Global Warrant for all purposes under the Warrant Agreement. Except as
provided below, owners of beneficial interests in the Global Warrant will not be
entitled to have the Warrants represented by such Global Warrant registered in
their names, will not receive or be entitled to receive physical delivery of
such Warrants in definitive form and will not be considered the owners or
Holders thereof under the Warrant Agreement. Accordingly, each person owning a
beneficial interest in the Global Warrant must rely on the procedures of the
Securities Depository and, if such person is not an Agent Member, on the
procedures of the Agent Member through which such person owns its interest, to
exercise any rights of a beneficial owner under the Warrant Agreement. The
Company understands that under existing industry practices, in the event that
the Company requests any action of Holders or that an owner of a beneficial
interest in the Global Warrant desires to give or take any action which a
beneficial owner is entitled to give or take under the Warrant Agreement, the
Securities Depository would authorize the Agent Members holding the relevant
beneficial interests to give or take such action, and such Agent Members would
authorize beneficial owners owning through such Agent Members to give or take
such action or would otherwise act upon the instructions of beneficial owners
through them.

  The Cash Settlement Value payable upon exercise of Warrants registered in the
name of the Securities Depository or its nominee will be paid by the Warrant
Agent to the Agent Members or, in the case of automatic exercise, to the
Securities Depository. None of the Company, the Warrant Agent or any other agent
of the Company or agent of the Warrant Agent will have any responsibility or
liability for any aspect of the records relating to or payments made on account
of beneficial ownership interests or for supervising or reviewing any records
relating to such beneficial ownership interests. The Company expects that the
Warrant Agent, upon the receipt of any payment of the Cash Settlement Value in
respect of any portion of the Global Warrant, will pay the relevant Agent Member
in an amount proportionate to its beneficial interest in such Global Warrant
being exercised and that such Agent Member will credit the accounts of the
beneficial owners of such Warrants. The Company expects that the Securities
Depository, in the case of automatic exercise, upon receipt of any payment of
the Cash Settlement Value in respect

                                       10
<PAGE>
 
of all or any portion of the Global Warrant, will credit the accounts of the
Agent Members with payment in amounts proportionate to their respective
beneficial interests in the portion of such Global Warrant so exercised, as
shown on the records of the Securities Depository. The Company also expects that
payments by Agent Members to owners of beneficial interests in the Global
Warrant will be governed by standing customer instructions and customary
practices, as is now the case with securities held for the accounts of customers
in bearer form or registered in "street name", and will be the responsibility of
such Agent Members. It is suggested that purchasers of Warrants with accounts at
more than one brokerage firm effect transactions in the Warrants, including
exercises, only through the brokerage firm or firms which hold that purchaser's
Warrants.

  If the Securities Depository is at any time unwilling or unable to continue as
depository and a successor Securities Depository is not appointed by the Company
within 90 days or if the Company is subject to certain events in bankruptcy,
insolvency or reorganization, the Company will issue Warrants in definitive form
in exchange for the Global Warrant. In addition, the Company may at any time
determine not to have the Warrants represented by the Global Warrant and, in
such event, will issue Warrants in definitive form in exchange for the Global
Warrant. In any such instance, an owner of a beneficial interest in the Global
Warrant will be entitled to have a number of Warrants equivalent to such
beneficial interest registered in its name and will be entitled to physical
delivery of such Warrants in definitive form.

  Cedel and Euroclear. Beneficial owners may hold their interests in Warrants
through Cedel or Euroclear if they are participants of such systems, or
indirectly through organizations which are participants in such systems. Cedel
and Euroclear will hold omnibus positions on behalf of their participants
through the facilities of DTC. All securities in Cedel or Euroclear are held on
a fungible basis without attribution of specific certificates to specific
securities clearance accounts.

  Exercises of Warrants by persons holding through Cedel or Euroclear
participants will be effected through DTC, in accordance with DTC rules, on
behalf of the relevant European international clearing system by its depositary;
however, such transactions will require delivery of exercise instructions to the
relevant European international clearing system by the participant in such
system in accordance with its rules and procedures and within its established
deadlines (European time). The relevant European international clearing system
will, if the exercise meets its requirements, deliver instructions to its
depositary to take action to effect its exercise of the Warrants on its behalf
by delivering Warrants through DTC and receiving payment in accordance with its
normal procedures for next-day funds settlement. Payments with respect to the
Warrants held through Cedel or Euroclear will be credited to the cash accounts
of Cedel participants or Euroclear participants in accordance with the relevant
system's rules and procedures, to the extent received by its depositary. See
"Exercise and Settlement of Warrants" herein.

  Cedel is incorporated under the laws of Luxembourg as a professional
depository. Cedel holds securities for its participating organizations and
facilitates the clearance and settlement of securities transactions between
Cedel participants through electronic book-entry changes in accounts of Cedel
participants, thereby eliminating the need for physical movement of
certificates. Transactions may be settled in Cedel in any of 28 currencies,
including U.S. dollars. Cedel provides to its participants, among other things,
services for safekeeping, administration, clearance and settlement of
internationally traded securities and securities lending and borrowing. Cedel
interfaces with domestic markets in several countries. As a professional
depository, Cedel is subject to regulation by the Luxembourg Monetary Institute.
Cedel participants are recognized financial institutions around the world,
including underwriters, securities brokers and dealers, banks, trust companies,
clearing corporations and certain other organizations and include an affiliate
of the Underwriter. Indirect access to Cedel is also available to others, such
as banks, brokers, dealers and trust companies that clear through or maintain a
custodial relationship with a Cedel participant, either directly or indirectly.

  The Euroclear System was created in 1968 to hold securities for participants
in the Euroclear System and to clear and settle transactions between Euroclear
participants through simultaneous electronic book-entry delivery against
payment, thereby eliminating the need for physical movement of certificates and
any risk from lack of simultaneous transfers of securities and cash.
Transactions may now be settled in any of 27 currencies, including U.S. dollars.
The Euroclear System includes various other services, including securities
lending and borrowing and interfaces with domestic markets in several countries
generally similar to the arrangements of cross-market transfers with DTC
described above. The Euroclear System is operated by the Brussels, Belgium
office of Morgan Guaranty Trust Company of New York (the "Euroclear Operator")
under contract with Euroclear Clearance System S.C., a Belgium cooperative
corporation (the "Cooperative"). Morgan Guaranty Trust Company of New York
("Morgan")

                                       11

is a member bank of the United States Federal Reserve System. All operations are
conducted by the Euroclear Operator, and all Euroclear securities clearance
accounts and Euroclear cash accounts are accounts with the Euroclear Operator,
not the Cooperative. The Cooperative establishes policy for the Euroclear System
on behalf of Euroclear participants. Euroclear participants include banks
(including central banks), securities brokers and dealers and other professional
financial intermediaries and include an affiliate of the Underwriter. Indirect
access to the Euroclear System is also available to other firms that clear
through or maintain a custodial relationship with a Euroclear participant,
either directly or indirectly.

  Securities clearance accounts and cash accounts with the Euroclear Operator
are governed by the Terms and Conditions Governing Use of Euroclear and the
related Operating Procedures of the Euroclear System, and applicable Belgian law
(collectively, the "Terms and Conditions"). The Terms and Conditions govern
transfers of securities and cash within the Euroclear System, withdrawal of
securities and cash from the Euroclear System, and receipt of payments with
respect to securities in the Euroclear System. All securities in the Euroclear
System are held on a fungible basis without attribution of specific certificates
to specific securities clearance accounts. The Euroclear Operator acts under the
Terms and Conditions only on behalf of Euroclear participants and has no record
of or relationship with persons holding through Euroclear participants.

  All information herein on Cedel and Euroclear is derived from Cedel or
Euroclear, as the case may be, and reflects the policies of such organizations;
such policies are subject to change without notice.


EXERCISE AND SETTLEMENT OF WARRANTS

  The Warrants are immediately exercisable, subject to postponement upon the
occurrence of an Extraordinary Event or a Market Disruption Event as described
under "Extraordinary Events and Market Disruption Events" herein, and will
expire on November 17, 1998 (the "Expiration Date"). Warrants not exercised
(including by reason of any such postponed exercise) at or before 1:00 p.m., New
York City time, on the earlier of (i) the fourth scheduled Index Calculation Day
immediately preceding the Expiration Date and (ii) the Early Expiration Date,
will be automatically exercised as described under "Automatic Exercise" below,
subject to earlier cancellation as described below under "Extraordinary Events
and Market Disruption Events". See "Minimum Exercise Amount" and "Maximum
Exercise Amount" below.

  A beneficial owner may exercise the Warrants on any New York Business Day
during the period from the date of the initial delivery of the Warrants until
1:00 p.m., New York City time, on the earlier of (i) the fourth scheduled Index
Calculation Day immediately preceding the Expiration Date and (ii) the Early
Expiration Date, by causing (x) such Warrants to be transferred free to the
Warrant Agent on the records of DTC and (y) a duly completed and executed
Exercise Notice to be delivered by an Agent Member on behalf of the beneficial
owner to the Warrant Agent. Forms of Exercise Notice may be obtained from the
Warrant Agent at the Warrant Agent's Office. The Warrant Agent's telephone
number and facsimile transmission number for this purpose are (201) 262-5444 and
(201) 262-7521, respectively.

  In the case of Warrants held through the facilities of Cedel or Euroclear, a
beneficial owner may exercise such Warrants on any New York Business Day during
the period from the date of initial delivery of the Warrants until 1:00 p.m.,
New York City time, on the earlier of (i) the fourth scheduled Index Calculation
Day immediately preceding the Expiration Date and (ii) the Early Expiration Date
by causing (x) such Warrants to be transferred to the Warrant Agent, by giving
appropriate instructions to the participant holding such Warrants in either the
Cedel or Euroclear system, as the case may be, and (y) a duly completed and
executed Exercise Notice to be delivered on behalf of the beneficial owner by
Cedel, in the case of Warrants held through Cedel, or such participant, in the
case of Warrants held through Euroclear, to the Warrant Agent. Forms of Exercise
Notice for Warrants held through the facilities of either Cedel or Euroclear may
be obtained from the Warrant Agent at the Warrant Agent's Office or from Cedel
or Euroclear.

  Except for Warrants subject to automatic exercise or held through the
facilities of Cedel or Euroclear, the "Exercise Date" for a Warrant will be (i)
the New York Business Day on which the Warrant Agent receives the Warrant and
Exercise Notice in proper form with respect to such Warrant, if received at or
prior to 1:00 p.m., New York City time, on such day, or (ii) if the Warrant
Agent receives such Warrant and Exercise Notice after 1:00 p.m.,

                                       12
<PAGE>
 
New York City time, on a New York Business Day, then the first New York Business
Day following such New York Business Day.

  In the case of Warrants held through the facilities of Cedel or Euroclear,
except for Warrants subject to automatic exercise, the "Exercise Date" for a
Warrant will be (i) the New York Business Day on which the Warrant Agent
receives the Exercise Notice in proper form with respect to such Warrant if such
Exercise Notice is received at or prior to 1:00 p.m., New York City time, on
such day, provided that the Warrant is received by the Warrant Agent by 1:00
p.m., New York City time, on the Valuation Date, or (ii) if the Warrant Agent
receives such Exercise Notice after 1:00 p.m., New York City time, on a New York
Business Day, then the first New York Business Day following such New York
Business Day, provided that the Warrant is received by 1:00 p.m., New York City
time, on the Valuation Date relating to exercises of Warrants on such succeeding
New York Business Day. In the event that the Warrant is received after 1:00
p.m., New York City time, on the Valuation Date, then the Exercise Date for such
Warrants will be the first New York Business Day following the day on which such
Warrants are received. If a beneficial owner of Warrants held through the
facilities of Cedel or Euroclear has exercised Warrants by delivering an
Exercise Notice in proper form with respect to such Warrants and the Valuation
Date is expected not to be a New York Business Day, such beneficial owner should
make arrangements so that the Warrants are delivered prior to such Valuation
Date in order to ensure that the Exercise Date for such Warrants is not
postponed as described above. In the case of Warrants held through the
facilities of Cedel or Euroclear, in order to ensure proper exercise on a given
New York Business Day, participants in Cedel or Euroclear must submit exercise
instructions to Cedel or Euroclear, as the case may be, by 10:00 a.m.,
Luxembourg time, in the case of Cedel and by 10:00 a.m., Brussels time (by
telex), or 11:00 a.m., Brussels time (by EUCLID), in the case of Euroclear. In
addition, in the case of book-entry exercises by means of the Euroclear System,
(i) participants must also transmit, by facsimile (facsimile number (201) 262-
7521), to the Warrant Agent a copy of the Exercise Notice submitted to Euroclear
by 1:00 p.m., New York City time, on the desired Exercise Date and (ii)
Euroclear must confirm by telex to the Warrant Agent by 9:00 a.m., New York City
time, on the Valuation Date, that the Warrants will be received by the Warrant
Agent on such date; provided, that if such telex communication is received after
9:00 a.m., New York City time, on the Valuation Date, the Company will be
entitled to direct the Warrant Agent to reject the related Exercise Notice or
waive the requirement for timely delivery of such telex communication.

  To ensure that an Exercise Notice and the related Warrants will be delivered
to the Warrant Agent before 1:00 p.m., New York City time, on a given New York
Business Day, a beneficial owner may need to give exercise instructions to his
broker or other intermediary substantially earlier than 1:00 p.m., New York City
time, on such day or even on the prior New York Business Day. Different
brokerage firms may have different cut-off times for accepting and implementing
exercise instructions from their customers. Therefore, beneficial owners should
consult with their brokers and other intermediaries, if applicable, as to
applicable cut-off times and other exercise mechanics.

  Except in the case of Warrants subject to automatic exercise and for Warrants
that upon exercise will entitle the Holder thereof to receive an Alternative
Settlement Amount in lieu of the Cash Settlement Amount, if on any Valuation
Date the Cash Settlement Amount for any Warrants would be zero, then the
attempted exercise of any such Warrants will be void and of no effect. Such
Warrants will be transferred back to the Agent Member that submitted them free
on the records of DTC and, in any such case, such beneficial owner will be
permitted to re-exercise such Warrants as described herein.

  The "Valuation Date" for a Warrant will be the applicable Exercise Date, if
such Exercise Date is an Index Calculation Day, or the immediately succeeding
Index Calculation Day, if such Exercise Date is not an Index Calculation Day,
subject to postponement upon the occurrence of an Extraordinary Event or a
Market Disruption Event as described below under "Extraordinary Events and
Market Disruption Events" or as a result of the exercise of a number of Warrants
exceeding the limits on exercise described below under "Maximum Exercise
Amount". "Index Calculation Day" means any day on which the NYSE is open for
trading and the Index or a Successor Index, if any, is calculated and published.
The following is an illustration of the timing of an Exercise Date and the
Valuation Date, assuming (i) that all relevant dates are New York Business Days
and Index Calculation Days, (ii) the absence of any intervening Extraordinary
Event or Market Disruption Event and (iii) the number of exercised Warrants does
not exceed the maximum permissible amount. If the Warrant Agent receives a
beneficial owner's Warrants and Exercise Notice in proper form at or prior to
1:00 p.m., New York City time, on Thursday, December 7, 1995, the Exercise Date
for such Warrants will be Thursday, December 7th and the Valuation Date for such
Warrants will be Thursday, December 7th (except that in the case of Warrants
held through the facilities of Cedel or Euroclear, the Warrants must be received
by 1:00 p.m., New York City time, on the Valuation Date; if such

                                       13
<PAGE>
 
Warrants are received after such time, then the Exercise Date for such Warrants
will be the day on which such Warrants are received or, if such day is not a New
York Business Day, the next succeeding New York Business Day, and the Valuation
Date for such Warrants will be the Exercise Date, if it is an Index Calculation
Day, or the first Index Calculation Day following such Exercise Date, if such
Exercise Date is not an Index Calculation Day).

  Following receipt of Warrants and the related Exercise Notice in proper form,
the Warrant Agent will, not later than 10:00 a.m., New York City time, on the
New York Business Day following the applicable Valuation Date (i) obtain the
Index Spot Price from the Calculation Agent, (ii) determine the Cash Settlement
Value of such Warrants and (iii) advise the Company of the aggregate Cash
Settlement Value of the exercised Warrants. The Company will be required to make
available to the Warrant Agent, no later than 3:00 p.m., New York City time, on
the fourth New York Business Day following the Valuation Date, funds in an
amount sufficient to pay such aggregate Cash Settlement Value. If the Company
has made such funds available by such time, the Warrant Agent will thereafter be
responsible for making funds available to each appropriate Agent Member
(including Citibank, N.A. and Morgan as custodians for Cedel and Euroclear,
respectively, who, in turn, will disburse payments to Cedel and Euroclear, as
the case may be, who will be responsible for disbursing such payments to each of
their respective participants, who, in turn, will be responsible for disbursing
payments to the beneficial owner it represents), and such participant will be
responsible for disbursing such payments to the beneficial owner it represents
and to each brokerage firm for which it acts as agent. Each such brokerage firm
will be responsible for disbursing funds to the beneficial owners it represents.

  The "Index Spot Price" for any Valuation Date on or prior to the fourth Index
Calculation Day preceding the Expiration Date will equal the closing value of
the Index, or, if applicable, the Successor Index, in New York on such date and
for any Valuation Date after the fourth Index Calculation Day preceding the
Expiration Date will equal the opening value of the Index, or, if applicable,
the Successor Index, in New York on such date as calculated by the Calculation
Agent using opening prices for the underlying stocks that constitute the Index
or Successor Index, as applicable. Since the opening value of the Index as
reported by FRC or a Successor Index published by its distributor will not
reflect the opening prices for the underlying stocks that constitute the Index
or Successor Index, the Calculation Agent will calculate an opening value for
the Index or Successor Index using the same method then used to calculate the
Index or Successor Index and such opening prices.

  "Calculation Agent" means MLPF&S or, in lieu thereof, another firm selected by
the Company to perform the functions of the Calculation Agent in connection with
the Warrants. The Calculation Agent is obligated to carry out its duties and
functions as Calculation Agent in good faith and using its reasonable judgment.
However, MLPF&S, in its capacity as Calculation Agent, will have no obligation
to take the interests of the Company or the beneficial owners into consideration
in the event it determines, composes or calculates the Cash Settlement Value or
Alternative Settlement Amount. The Calculation Agent and its affiliates may from
time to time engage in transactions involving the Underlying Stocks for their
proprietary accounts and for other accounts under their management, which may
influence the value of such Underlying Stocks. The Calculation Agent and its
affiliates will also be the writers of the hedge of the Company's obligations
under the Warrants and will be obligated to pay to the Company upon exercise of
the Warrants an amount equal to the value of the Warrants. Accordingly, under
certain circumstances, conflicts of interest may arise between the Calculation
Agent's responsibilities as Calculation Agent with respect to the Warrants and
its obligations under its hedge and its status as a subsidiary of the Company.
In addition, because the Calculation Agent is an affiliate of the Company,
certain conflicts of interest may arise in connection with the Calculation Agent
performing its role as Calculation Agent. The Calculation Agent, as a registered
broker-dealer, is required to maintain policies and procedures regarding the
handling and use of confidential proprietary information, and such policies and
procedures will be in effect throughout the term of the Warrants to restrict the
use of information relating to any calculation of the Cash Settlement Value
prior to its dissemination.


AUTOMATIC EXERCISE

  All Warrants for which the Warrant Agent has not received a valid Exercise
Notice at or prior to 1:00 p.m., New York City time, or for which the Warrant
Agent has received a valid Exercise Notice but with respect to which timely
delivery of the relevant Warrant has not been made, together with any Warrants
the Valuation Date for which has at such time been postponed as described under
"Extraordinary Events and Market Disruption Events" below, on (i) the fourth
scheduled Index Calculation Day immediately preceding the Expiration Date, or
(ii) the close of business on the New York Business Day on which the Warrants
are delisted from, or permanently suspended from trading on, the AMEX and the
Warrants are not simultaneously accepted for trading pursuant to the rules of
another

                                       14
<PAGE>
 
Self-Regulatory Organization (the "Early Expiration Date") will be deemed
automatically exercised on the first scheduled Index Calculation Day immediately
preceding such Expiration Date or Early Expiration Date, as the case may be
(such first scheduled Index Calculation Day will be deemed the Exercise Date),
and the Cash Settlement Value, if any (determined as provided under "Exercise
and Settlement of Warrants"), of such automatically exercised Warrants will be
paid and settlement shall otherwise occur as described under "Book-Entry
Procedures and Settlement" and "Exercise and Settlement of Warrants". The
Company will notify Holders as soon as practicable of such delisting or trading
suspension. The Company agreed in the Warrant Agreement that it will not seek
delisting of the Warrants or suspension of their trading on the AMEX.

  In the event the Warrants are canceled by the Company because of the
continuance of an Extraordinary Event as described under "Extraordinary Events
and Market Disruption Events" below, Warrants not previously exercised shall be
automatically exercised on the basis that the Valuation Date for such Warrants
shall be the Cancellation Date, and the Alternative Settlement Amount of such
automatically exercised Warrants will be paid on the fourth New York Business
Day following such Valuation Date. Settlement shall otherwise occur as described
under "Book-Entry Procedures and Settlement" and "Exercise and Settlement of
Warrants".


MINIMUM EXERCISE AMOUNT

  No fewer than 100 Warrants may be exercised by or on behalf of a beneficial
owner at any one time, except in the case of automatic exercise or exercise upon
cancellation of the Warrants as described under "Extraordinary Events and Market
Disruption Events" below. Accordingly, except in the case of automatic exercise
of the Warrants or upon cancellation of the Warrants, beneficial owners with
fewer than 100 Warrants, as the case may be, will need either to sell their
Warrants or to purchase additional Warrants, thereby incurring transaction
costs, in order to realize proceeds from their investment. Warrants held through
one Agent Member (including participants in Cedel or Euroclear) may not be
combined with Warrants held through another Agent Member in order to satisfy the
minimum exercise requirement.


MAXIMUM EXERCISE AMOUNT

  All exercises of Warrants (other than on automatic exercise) are subject, at
the Company's option, to the limitation that not more than 20% of the Warrants
originally issued (provided, however, that no more than 10% of the Warrants
originally issued shall be exercised for the account of any beneficial owner)
may be exercised on any Exercise Date and not more than 10% of the Warrants
originally issued may be exercised by or on behalf of any beneficial owner,
either individually or in concert with any other beneficial owner, on any
Exercise Date. If any New York Business Day would otherwise, under the terms of
the Warrant Agreement, be the Exercise Date in respect to more than 20% of the
Warrants originally issued, then at the Company's election, 20% of the Warrants
originally issued (provided, however, that no more than 10% of the Warrants
originally issued shall be exercised for the account of any beneficial owner)
shall be deemed exercised on such Exercise Date (selected by the Warrant Agent
on a pro rata basis, but if, as a result of such pro rata selection, any
beneficial owner of Warrants would be deemed to have exercised fewer than 100
Warrants, then the Warrant Agent shall first select an additional amount of such
beneficial owner's Warrants so that no beneficial owner shall be deemed to have
exercised fewer than 100 Warrants), and the remainder of such warrants (the
"Remaining Warrants") shall be deemed exercised on the following New York
Business Day (subject to successive applications of this provision); provided
that any Remaining Warrants for which an Exercise Notice was delivered on a
given Exercise Date shall be deemed exercised before any other Warrants for
which an Exercise Notice was delivered on a later Exercise Date. If any
beneficial owner attempts to exercise more than 10% of the Warrants originally
issued on any New York Business Day, then, at the Company's election, 10% of
such Warrants shall be deemed exercised on such New York Business Day and the
remainder shall be deemed exercised on the following New York Business Day
(subject to successive applications of this provision). As a result of any
postponed exercise as described above, such beneficial owners will receive a
Cash Settlement Value determined as of a date later than the otherwise
applicable Valuation Date. In any such case, as a result of any such
postponement, the Cash Settlement Value actually received by such beneficial
owners may be lower than the otherwise applicable Cash Settlement Value if the
Valuation Date of the Warrants had not been postponed.

                                       15
<PAGE>
 
SUCCESSOR INDEX

  If FRC discontinues publication of the Index and FRC or another entity
publishes a successor or substitute index that the Calculation Agent determines,
in its sole discretion, to be comparable to the Index (any such index being
referred to herein as a "Successor Index"), then, upon the Calculation Agent's
notification of such determination to the Warrant Agent and the Company, the
Calculation Agent will substitute the Successor Index as calculated by FRC or
such other entity for the Index and calculate the Cash Settlement Value upon an
exercise as described above. Upon any selection by the Calculation Agent of a
Successor Index, the Company shall promptly give notice to the beneficial owners
by publication in a United States newspaper with a national circulation
(currently expected to be The Wall Street Journal), within three New York
Business Days of such selection.

  If FRC discontinues publication of the Index and a Successor Index is not
selected by the Calculation Agent or is no longer published on any Valuation
Date, the value to be substituted for the Index for any Valuation Date used to
calculate the Cash Settlement Value upon exercise will be a value computed by
the Calculation Agent on each Valuation Date in accordance with the procedures
last used to calculate the Index prior to such discontinuance.

  If a Successor Index is selected or the Calculation Agent calculates a value
as a substitute for the Index, such Successor Index or value shall be
substituted for the Index for all purposes, including for purposes of
determining whether a Market Disruption Event or Extraordinary Event exists. If
the Calculation Agent calculates a value as a substitute for the Index, "Index
Calculation Day" shall mean any day on which the Calculation Agent is able to
calculate such value.

  If at any time the method of calculating the Index or any Successor Index, as
the case may be, or the value thereof, is changed in a material respect, or if
the Index is in any other way modified so that such Index does not, in the
opinion of the Calculation Agent, fairly represent the value of the Index had
such changes or modifications not been made, then, from and after such time, the
Calculation Agent shall, at the close of business in New York, New York, on each
Valuation Date, make such adjustments as, in the good faith judgment of the
Calculation Agent, may be necessary in order to arrive at a calculation of a
value of a stock index comparable to the Index or any Successor Index, as the
case may be, as if such changes or modifications had not been made, and
calculate such Closing Index Value with reference to the Index or any Successor
Index, as the case may be, as adjusted. Accordingly, if the method of
calculating the Index or any Successor Index, as the case may be, is modified so
that the value of such Index or such Successor Index is a fraction or a multiple
of what it would have been if it had not been modified (e.g., due to a split in
the Index), the Calculation Agent shall adjust the Index in order to arrive at a
value of the Index or such Successor Index as if it had not been modified (e.g.,
as if such split had not occurred).


EXTRAORDINARY EVENTS AND MARKET DISRUPTION EVENTS

  Extraordinary Events. The Warrant Agreement provides that if the Calculation
Agent determines that an Extraordinary Event has occurred and is continuing on
the Index Business Day with respect to which the Index Spot Price on a Valuation
Date is to be determined (the "Applicable Index Business Day"), then the Cash
Settlement Value in respect of an exercise shall be calculated on the basis that
the Valuation Date shall be the next Index Calculation Day following an
Applicable Index Business Day on which there is no Extraordinary Event or Market
Disruption Event; provided that if a Valuation Date has not occurred on or prior
to the Expiration Date or the Early Expiration Date, the Holders will receive
the Alternative Settlement Amount in lieu of the Cash Settlement Value which
shall be calculated as if the Warrants had been cancelled on the Expiration Date
or the Early Expiration Date, as the case may be. The Company shall promptly
give notice to the beneficial owners by publication in a United States newspaper
with a national circulation (currently expected to be The Wall Street Journal),
if an Extraordinary Event shall have occurred.

  "Extraordinary Event" means any of the following events:

  (i) a suspension or absence of trading on the NYSE, AMEX or the over-the-
counter market of all the Underlying Stocks which then comprise the Index or a
Successor Index;

                                       16
<PAGE>
 
  (ii) the enactment, publication, decree or other promulgation of any statute,
regulation, rule or order of any court or any other U.S. or non-U.S.
governmental authority that would make it unlawful for the Company to perform
any of its obligations under the Warrant Agreement or the Warrants; or

  (iii) any outbreak or escalation of hostilities or other national or
international calamity or crises (including, without limitation, natural
calamities that in the reasonable opinion of the Calculation Agent may
materially and adversely affect the economy of the United States or the trading
of securities generally on the NYSE, AMEX or the over-the-counter market) that
has or will have a material adverse effect on the ability of the Company to
perform its obligations under the Warrants or to modify the hedge of its
position with respect to the Index or the Underlying Stocks.

  For the purposes of determining whether an Extraordinary Event has occurred:
(1) a limitation on the hours or number of days of trading on an exchange will
not constitute an Extraordinary Event if it results from an announced change in
the regular business hours of such exchange and (2) an "absence of trading" on
an exchange will not include any time when such exchange itself is closed for
trading under ordinary circumstances.

  If the Calculation Agent determines that an Extraordinary Event has occurred
and is continuing, and if the Extraordinary Event is expected by the Calculation
Agent to continue, the Company may immediately cancel all outstanding Warrants
by notifying the Warrant Agent of such cancellation (the date such notice is
given being the "Cancellation Date"), and each beneficial owner's rights under
the Warrants and the Warrant Agreement shall thereupon cease; provided that each
Warrant shall be automatically exercised on the basis that the Valuation Date
for such Warrant shall be the Cancellation Date, if the Cancellation Date is an
Index Calculation Day, or the immediately succeeding Index Calculation Day, if
the Cancellation Date is not an Index Calculation Day, and the beneficial owner
of each such Warrant will receive, in lieu of the Cash Settlement Value of such
Warrant, an amount (the "Alternative Settlement Amount"), determined by the
Calculation Agent, which is the greater of (i) the average of the last sale
prices, as available, of the Warrants on the AMEX (or any successor securities
exchange on which the Warrants are listed) on the 30 trading days preceding the
date on which such Extraordinary Event was declared; provided that, if the
Warrants were not traded on the AMEX (or such successor securities exchange) on
at least 20 of such trading days, no effect will be given to this clause (i) for
the purpose of determining the Alternative Settlement Amount, and (ii) the
amount "X" calculated using the formula set forth below:

                          [  T  x  A  ]
                 X = I  + [ ---   --- ]
                          [  2     B  ]
where

  I = The Cash Settlement Value of the Warrants determined as described under
"Cash Settlement Value" above, but subject to the following modifications:

  (1) if the Cancellation Date for such Warrants is a date on which the Index or
a Successor Index is calculated and published, for the purpose of determining
such Cash Settlement Value, the Index Spot Price will be determined as of such
Cancellation Date except that, if the Index Spot Price as of such day is less
than 90% of the Index Spot Price as of the immediately preceding Index
Calculation Day, then the Index Spot Price will be deemed to be 90% of the Index
Spot Price on such preceding Index Calculation Day; or

  (2) if the Cancellation Date for such Warrants is a date on which the Index or
a Successor Index is not calculated or published, for the purpose of determining
such Cash Settlement Value, the Index Spot Price will be deemed to be the lesser
of (i) the Index Spot Price as of the first Index Calculation Day immediately
preceding the Cancellation Date except that, if the Index Spot Price as of such
day is less than 90% of the Index Spot Price as of the second Index Calculation
Day immediately preceding such Cancellation Date, 90% of the Index Spot Price as
of such second Index Calculation Day and (ii) the arithmetic average of four
amounts, being (a) the Index Spot Price at each of the three successive Index
Calculation Days immediately preceding the Cancellation Date and (b) the Index
Spot Price at the next Index Calculation Day, provided that if an Extraordinary
Event continues for 30 consecutive days immediately following such Cancellation
Date, then the Calculation Agent shall calculate an amount which, in its
reasonable opinion, fairly reflects the value of the Underlying Stocks on the
Index Calculation Day immediately following such Cancellation Date which,
subject to approval by the Company (such approval not to be unreasonably
withheld), shall for purposes of calculating the amount under this clause
(2)(ii) be treated as the figure arrived at under clause (2)(ii)(b) above;

                                       17
<PAGE>
 
  T = U.S.$3.15, the initial offering price per Warrant;

  A = the total number of days from but excluding the Cancellation Date for such
Warrants to and including the Expiration Date; and

  B = the total number of days from but excluding the date the Warrants were
initially sold to and including the Expiration Date.

  For the purposes of determining "I" in the above formula, in the event that
the Calculation Agent and the Company are required to have, but have not, after
good faith consultation with each other and within five days following the first
day upon which such Alternative Settlement Amount may be calculated in
accordance with the above formula, agreed upon a figure under clause (2)(ii)(b)
which fairly reflects the value of the Underlying Stocks on the Cancellation
Date, then the Calculation Agent shall promptly nominate a third party, subject
to approval by the Company (such approval not to be unreasonably withheld), to
determine such figure and calculate the Alternative Settlement Amount in
accordance with the above formula. Such party shall act as an independent expert
and not as an agent of the Company or the Calculation Agent, and its calculation
and determination of the Alternative Settlement Amount shall, absent manifest
error, be final and binding on the Company, the Warrant Agent, the Calculation
Agent and the Holders. Any such calculations will be made available to Holders
for inspection at the Warrant Agent's Office. Neither the Company nor such third
party shall have any responsibility for good faith errors or omissions in
calculating the Alternative Settlement Amount. Under certain circumstances, the
duties of MLPF&S as Calculation Agent in determining the existence of
Extraordinary Events could conflict with the interests of MLPF&S as an affiliate
of the issuer of the Warrants, Merrill Lynch & Co., Inc.

  Market Disruption Events. If the Calculation Agent determines that on a
Valuation Date a Market Disruption Event has occurred and is continuing, the
Valuation Date shall be postponed to the first succeeding Index Calculation Day
on which no Market Disruption Event occurs; provided that, if the Valuation Date
has not occurred on or prior to the fifth Index Business Day following an
Exercise Date because of Market Disruption Events, the Calculation Agent shall,
on such fifth Index Business Day, calculate an amount which, in its reasonable
opinion, fairly reflects the value of the Underlying Stocks on such day in order
to determine the Cash Settlement Value.

  "Market Disruption Event" means with respect to any Valuation Date the
occurrence or existence during the one-half hour period that ends at the
determination of the Closing Index Value for such Index Business Day of:

  (i) a suspension, material limitation or absence of trading on the NYSE, AMEX
or the over-the-counter market of 20% or more of the Underlying Stocks which
then comprise the Index or a Successor Index during the one-half hour period
preceding the close of trading on the applicable exchange; or

  (ii) the suspension or material limitation on the Chicago Board Options
Exchange (the "CBOE"), Chicago Mercantile Exchange (the "CME") or any other
major futures or securities market of trading in futures or options contracts
related to the Index or a Successor Index during the one-half hour period
preceding the close of trading on the applicable exchange.

  For the purposes of determining whether a Market Disruption Event has
occurred: (i) a limitation on the hours or number of days of trading will not
constitute a Market Disruption Event if it results from an announced change in
the regular business hours of the relevant exchange, (ii) a decision to
permanently discontinue trading in the relevant futures or options contract will
not constitute a Market Disruption Event, (iii) a suspension in trading in a
futures or options contract on the Index by a major securities market by reason
of (a) a price change violating limits set by such securities market, (b) an
imbalance of orders relating to such contracts or (c) a disparity in bid and ask
quotes relating to such contracts will constitute a suspension or material
limitation of trading in futures or options contracts related to the Index, (iv)
an absence of trading on an exchange will not include any time when such
exchange is closed for trading under ordinary circumstances, and (v) the
occurrence of an Extraordinary Event described in Clause (i) of Extraordinary
Event will not constitute, and will supersede the occurrence of, a Market
Disruption Event. Under certain circumstances, the duties of MLPF&S as
Calculation Agent in determining the existence of Market Disruption Events could
conflict with the interests of MLPF&S as an affiliate of the issuer of the
Warrants, Merrill Lynch & Co., Inc.

LISTING OF THE WARRANTS

  The Warrants are listed on the AMEX. The AMEX will expect to cease trading the
Warrants on such Exchange as of the close of business on the Expiration Date.


MODIFICATION

  The Warrant Agreement and the terms of the Warrants may be amended by the
Company and the Warrant Agent without the consent of the beneficial owners of
any Warrants for the purpose of curing any ambiguity, or of curing, correcting
or supplementing any defective or inconsistent provision contained therein, or
in any other manner which the Company may deem necessary or desirable and which
will not materially and adversely affect the interests of the beneficial owners
of the Warrants.

  The Company and the Warrant Agent also may modify or amend the Warrant
Agreement and the terms of the Warrants, with the consent of the beneficial
owners of not less than a majority in number of the then outstanding Warrants
affected, provided that no such modification or amendment that changes the Index
Strike Price so as to adversely affect the beneficial owner, shortens the period
of time during which the Warrants may be exercised or otherwise materially and
adversely affects the exercise rights of the beneficial owners of the Warrants
or reduces the percentage of the number of outstanding Warrants, the consent of
whose beneficial owners is required for modification or amendment of such
Warrant Agreement or the terms of such Warrants may be made without the consent
of the beneficial owners of Warrants affected thereby.


MERGER AND CONSOLIDATION

  The Company may consolidate or merge with or into any other corporation, and
the Company may sell, lease or convey all or substantially all of its assets to
any corporation, provided that the corporation (if other than the Company)
formed by or resulting from any such consolidation or merger or which shall have
received such assets shall be a corporation organized and existing under the
laws of the United States of America or a state thereof and shall assume payment
of the Cash Settlement Value or Alternative Settlement Amount with respect to
all unexercised Warrants, according to their tenor, and the due and punctual
performance and observance of all of the covenants and conditions of the Warrant
Agreement and of the Warrants to be performed by the Company.


                                   THE INDEX

  Unless otherwise stated, all information herein on the Index is derived from
FRC or other publicly available sources. Such information reflects the policies
of FRC as stated in such sources and such policies are subject to change by FRC.
FRC is under no obligation to continue to publish the Index and may discontinue
publication of the Index at any time.

  The Index is an index calculated, published and disseminated by FRC, and
measures the composite price performance of stocks of 2000 companies domiciled
in the U.S. and its territories. All 2000 stocks are traded on either the NYSE,
AMEX or the over-the-counter market and form a part of the Russell 3000 Index.
The Russell 3000 Index is composed of the 3,000 largest U.S. companies as
determined by market capitalization and represents approximately 98% of the
investable U.S. equity market. As of May 31, 1995, the average market
capitalization of companies included in the Russell 3000 Index was $1.74
billion.

  The Index consists of the smallest 2,000 companies included in the Russell
3000 Index and represents approximately 11% of the total market capitalization
of the Russell 3000 Index. The Index is designed to track the performance of the
small capitalization segment of the U.S. equity market. As of May 31, 1995, the
average market capitalization of companies included in the Index was $288
million.

  Only common stocks belonging to corporations domiciled in the U.S. and its
territories are eligible for inclusion in the Russell 3000 Index, and
subsequently the Index. Stocks traded on the different exchanges in the U.S. but
domiciled in other countries are excluded. Preferred stock, convertible
preferred stock, participating preferred stock, paired shares, warrants and
rights are also excluded. Trust receipts, Royalty Trusts, limited liability
companies, OTC

                                       19
<PAGE>
 
Bulletin Board companies, pink sheets, closed-end mutual funds, and limited
partnerships that are traded on any of the exchanges, are also ineligible for
inclusion. Real Estate Investment Trusts and Beneficial Trusts are eligible for
inclusion, however. Generally, only one class of securities of a company is
allowed in the Russell 3000 Index, although exceptions to this general rule have
been made where FRC has determined that each class of securities acts
independent of the other.

  The primary criteria used to determine the initial list of securities eligible
for the Russell 3000 Index is total market capitalization which is defined as
the price of the shares times the total number of shares outstanding. Based on
closing values on May 31st of each year, FRC reconstitutes the composition of
the Russell 3000 Index based on the then existing market capitalization of the
companies eligible for inclusion. As of June 30th of each year, the Index is
adjusted to reflect the reconstitution for that year. Publication of the Index
began on January 1, 1987.

  As a capitalization-weighted index, Russell 2000 reflects changes in the
capitalization (market value) of the component stocks relative to the
capitalization on a base date. The current Index value is calculated by adding
the market values of the Index's component stocks, which are derived by
multiplying the price of each stock by the number of shares outstanding, to
arrive at the total market capitalization of the 2000 stocks. The total market
capitalization is then divided by a divisor, which represents the "adjusted"
capitalization of the Index on the base date of December 31, 1986. To calculate
the Index, last sale prices will be used for exchange-traded and NASDAQ stocks.
If a component stock is not open for trading, the most recently traded price for
that security will be used in calculating the Index. In order to provide
continuity for the Index's value, the divisor is adjusted periodically to
reflect such events as changes in the number of common shares outstanding for
component stocks, company additions or deletions, corporate restructurings and
other capitalization changes.

  All disclosure contained in this Prospectus regarding the Index, or its
publisher, is derived from publicly available information. All copyrights and
other intellectual property rights relating to the Index are owned by FRC. FRC
has no relationship with the Company or the Warrants; it does not sponsor,
endorse, authorize, sell or promote the Warrants, and has no obligation or
liability in connection with the administration, marketing or trading of the
Warrants.

Note:  The Index included fewer than 2000 stocks (1,975) as of September 30,
       1995 due to company attrition (e.g., mergers, bankruptcies, etc.).

As of September 30, 1995, the ten largest holdings in the Index represented 2.1%
of the aggregate market capitalization of the Index. Thirty-three of the 1,975
stocks in the Index were also components of the S&P 500 Index. These 33 stocks
represented 3.1% of the Index market capitalization. The dividend yield on the
Index was 1.48%.

     A potential investor should review the historical performance of the Index.
The historical performance of the Index should not be taken as an indication of
future performance, and no assurance can be given that the Index will increase
sufficiently to cause the Warrants to have a Cash Settlement Value in excess of
zero on the relevant Valuation Date.

            CURRENCY PROTECTED NOTES ("CPNS") DUE DECEMBER 31, 1998

  On July 7, 1993, Merrill Lynch & Co., Inc. (the "Company") issued $25,000,000
of Currency Protected Notes ("CPNs") due December 31, 1998 (the "Notes") in
denominations of $1,000 and integral multiples  thereof.  As of the date of this
Prospectus, $15,000,000 aggregate principal amount of the Notes remain
outstanding.  The Notes will mature and be repayable at 100% of the principal
amount thereof  on December 31, 1998 (the "Maturity Date"). Interest payments
will be payable  with respect to the Notes semiannually on June 30 and December
31 of each year,  as described below ("June Payment Dates" and "December Payment
Dates",  respectively and together the "Payment Dates").  The Notes are not
subject to redemption by the Holders or the Company prior to the Maturity Date.

  The Company will make interest payments on the Notes on each June and
December Payment Date for the period from and including the last Payment Date
for which interest was paid, to but excluding such Payment Date (each, an
"Interest Period") at a per annum  rate equal to the sum of (i) the Minimum
Payment Rate (3%), and (ii) the  Supplemental Payment Rate. The "Supplemental
Payment Rate" for an Interest  Period will equal 4.5 multiplied by the
difference between 6.15% minus the  Index Rate (as defined below) as of the
applicable Determination Date  (generally the seventh scheduled NYSE Business
Day (as defined below) prior to the applicable  Payment Date). In no event,
however, will the payments on the Notes for any  period be at a rate less than
the Minimum Payment Rate. The "Index Rate" will  be the average bankers'
acceptance rate in Canadian Dollars for a term of six  months, as more fully
described herein (the "Canadian BA Rate").

  For information as to the calculation of the amount payable in any calendar
year, see "Description of Notes" in this Prospectus.  FOR OTHER INFORMATION THAT
SHOULD BE CONSIDERED BY PROSPECTIVE INVESTORS, SEE "RISK FACTORS" BEGINNING ON
PAGE 3 OF THIS PROSPECTUS.

  Ownership of the Notes will be maintained in book-entry form by or through the
Securities Depository. Beneficial owners of the Notes will not have the right to
receive physical certificates evidencing their ownership except under the
limited circumstances described herein.

  The Notes have been listed on the New York Stock Exchange under the symbol
"MERCN 98".

and fixed charges.  "Fixed charges" consists of interest costs, amortization of
debt expense, preferred stock dividend requirements of majority-owned
subsidiaries, and that portion of rentals estimated to be representative of the
interest factor.


                                  RISK FACTORS
SEMIANNUAL PAYMENTS

  If the Index Rate applicable to a Payment Date equals or exceeds 6.15%,
beneficial owners of the Notes will receive only the Minimum Payment Rate
payable with respect to the Notes on such Payment Date, even if the Index Rate
at some point since the preceding Determination Date or issue date, as the case
may be, was less than 6.15%. The interest rate for any Interest Period generally
will be determined seven NYSE Business Days prior to the end of such Interest
Period.

                                       3
<PAGE>
 
  Beneficial owners of the Notes will receive total annual payments on the Notes
at a rate equal to at least the Minimum Payment Rate, and will be repaid 100% of
the principal amount of the Notes at the Maturity Date. The amount payable on
any Payment Date is subject to the conditions described under "Description of
Notes--Semiannual Payments". A beneficial owner of the Notes may receive
payments with respect to the Notes equal to only the Minimum Payment Rate for
each Interest Period at the times specified herein, and such payments are below
what the Company would pay as interest as of the date hereof if the Company
issued non-callable senior debt securities with a similar maturity as that of
the Notes. The return of principal at the Maturity Date and the payment of the
Minimum Payment Rate with respect to the Notes are not expected to reflect the
full opportunity costs implied by inflation or other factors relating to the
time value of money.

  The amount payable on the Notes based on the Index Rate will not produce the
same return as any investment in Canadian bankers' acceptances with maturities
of six months because, among other reasons, interest and principal payable on
the Notes will be in U.S. Dollars while interest and principal payable on such
bankers' acceptances are payable in Canadian Dollars and the U.S. Dollar value
of such Canadian Dollar payments may increase or decrease depending on the U.S.
Dollar/Canadian Dollar exchange rate. Since the principal and interest payments
on the Notes will be made in U.S. Dollars, such payments will not be subject to
changes in Canadian Dollar/U.S. Dollar exchange rates. Such exchange rate
changes may have a direct effect on the market demand for, and thus the price
of, such bankers' acceptances.

  The formula used to determine the interest payable with respect to any Payment
Date contains a multiple which increases the effect of any change in the
applicable Index Rate.

TRADING

  The Notes have been listed on the New York Stock Exchange under the symbol
"MERCN 98".  It is expected that the secondary market for the Notes will be
affected by the creditworthiness of the Company and by a number of other
factors. It is possible to view the Notes as the economic equivalent of a debt
obligation plus a series of cash settlement options; however, there can be no
assurance that the Notes will not trade in the secondary market at a discount
from the aggregate value of such economic components, if such economic
components were valued and capable of being traded separately.

  The trading values of the Notes may be affected by a number of interrelated
factors, including those listed below. The following is the expected effect on
the trading value of the Notes of each of the factors listed below. The
following discussion of each separate factor generally assumes that all other
factors are held constant, although the actual interrelationship between certain
of such factors is complex.

  Value of the Index Rate. The trading value of the Notes is expected to depend
  significantly on the extent to which, if at all, the Index Rate is less than
  6.15%. If, however, Notes are sold at a time when the Index Rate is less than
  6.15%, the sale price may be at a discount from the amount expected to be
  payable to the beneficial owner if such price were to prevail until the next
  applicable Determination Date. Furthermore, the price at which a beneficial
  owner will be able to sell Notes prior to a Payment Date may be at a discount,
  which could be substantial, from the principal amount thereof, if, at such
  time, the price of the Index Rate is above, equal to or not sufficiently below
  6.15%.

  Volatility of the Index Rate. If the volatility of the Index Rate increases,
  the trading value of the Notes is expected to increase. If the volatility of
  the Index Rate decreases, the trading value of the Notes is expected to
  decrease.

  Interest Rates. In general, if U.S. interest rates increase, the value of the
  Notes is expected to decrease. If U.S. interest rates decrease, the value of
  the Notes is generally expected to increase. In addition, Canadian interest
  rates will affect the Index Rate. In general, if Canadian interest rates
  increase, the Index Rate is expected to

                                       4
<PAGE>
 
  increase, and therefore the value of the Notes is expected to decrease. If
  Canadian interest rates decrease, the Index Rate is expected to decrease, and
  therefore the value of the Notes is expected to increase.

  Time Remaining to Payment Dates. The Notes may trade at a value above that
  which may be inferred from the level of interest rates and the Index Rate.
  This difference will reflect a "time premium" due to expectations concerning
  the value of the Index Rate during the period prior to each Payment Date. As
  the time remaining to each Payment Date decreases, however, this time premium
  may decrease, thus decreasing the trading value of the Notes.

  Time Remaining to Maturity Date. As the number of remaining Payment Dates
  decreases, the value of the remaining rights to receive payments based on the
  value of the Index Rate will decrease, thus decreasing the value of the Notes.
  Furthermore, as the time to the Maturity Date decreases, the value of the
  fixed payments (i.e., the Minimum Annual Payments and the payment of the
  principal amount at the maturity of the Notes) is expected to increase, thus
  increasing the value of the Notes.

OTHER CONSIDERATIONS

  It is suggested that prospective investors who consider purchasing the Notes
should reach an investment decision only after carefully considering the
suitability of the Notes in the light of their particular circumstances.

  Investors should also consider the tax consequences of investing in the Notes
and should consult their tax advisors.


                              DESCRIPTION OF NOTES
GENERAL

  The Notes were issued as a series of Senior Debt Securities under the Senior
Indenture, dated as of April 1, 1983, as amended and restated, which is more
fully described below. The Notes will mature, and the principal of the Notes
will be repayable at par, on December 31, 1998.

  The Notes are not subject to redemption prior to the Maturity Date by the
Company or at the option of any Holder. Upon the occurrence of an Event of
Default with respect to the Notes, however, Holders of the Notes or the Senior
Debt Trustee may accelerate the maturity of the Notes, as described under
"Description of Notes--Events of Default and Acceleration" and "Other Terms--
Events of Default" in this Prospectus.

  The Notes were issued in denominations of $1,000 and integral multiples
thereof.

SEMIANNUAL PAYMENTS

  The Company will make semiannual payments on the Notes each June 30 and
December 31 ("June Payment Dates" and "December Payment Dates", respectively,
and together the "Payment Dates"), as described below, to the persons in whose
names the Notes are registered on the next preceding June 29 or December 30,
except as provided below. Notwithstanding the foregoing, if it is known three
Business Days prior to December 31 that December 31 will not be a Business Day,
the amount payable by the Company with respect to such December Payment Date
will be made on the Business Day immediately preceding such December 31 to the
persons in whose names the Notes are registered on the second Business Day
immediately preceding such December 31 and the amount so paid will equal an
amount as if interest had accrued through December 31.

  The Company will pay interest on the Notes on each June and December Payment
Date for the period since the last Payment Date for which interest was paid, to
but excluding such Payment Date (each, an "Interest Period")

                                       5
<PAGE>
 
at a rate per annum equal to the sum of (i) the Minimum Payment Rate (3% per
annum), and (ii) the Supplemental Payment Rate. The "Supplemental Payment Rate"
for an Interest Period will equal 4.5 multiplied by the difference between 6.15%
minus the Index Rate as of the Determination Date in such Interest Period. In no
event, however, will the payments on the Notes for any period be at a rate less
than the Minimum Payment Rate.  The "Index Rate" will equal the Canadian BA Rate
(as defined below).  Interest payable with respect to any Payment Date will be
computed on the basis of a year consisting of 360 days of twelve 30-day months.

  State Street Bank and Trust Company is the calculation agent (the "Calculation
Agent") with respect to the Notes. All determinations made by the Calculation
Agent shall be at the sole discretion of the Calculation Agent and, absent a
determination by the Calculation Agent of a manifest error, shall be conclusive
for all purposes and binding on the Company and the Holders of the Notes. All
percentages resulting from any calculation on the Notes will be rounded to the
nearest one-hundredth of a percentage point, with five one-thousandth of a
percentage point rounded upwards (e.g., 9.875% (or .09875) would be rounded to
9.88% (or .0988)), and all dollar amounts used in or resulting from such
calculation will be rounded to the nearest cent with one-half cent being rounded
upwards.

  If the Index Rate applicable to a Payment Date is equal to or exceeds 6.15%,
beneficial owners of the Notes will receive only the Minimum Payment Rate for
the Interest Period preceding such Payment Date, even if the Index Rate at some
point since the preceding Determination Date or the original issue date, as the
case may be, was less than 6.15%.

  The following table shows the annual payment rate payable on the Notes for any
Interest Period assuming various Index Rates on a Determination Date.

  A potential investor should review the historical performance of the Index
Rate. The historical performance of the Index Rate should not be taken as an
indication of future performance, and no assurance can be given that the Index
Rate will increase sufficiently to cause the beneficial owners of the Notes to
receive an amount in excess of the principal amount and the Minimum Payment Rate
at the maturity of the Notes or the Minimum Payment Rate in prior years.

CANADIAN DOLLAR BANKERS' ACCEPTANCE RATE

  The "Canadian BA Rate" shall be determined for each Determination Date as
follows:

     (i) On the relevant Determination Date, the Canadian BA Rate will be
  determined on the basis of the average bankers' acceptance rate in Canadian
  Dollars for a term of six months, commencing on the related Determination
  Date, which appears on the Reuters Screen Page CDOR (as defined below), as of
  10:00 A.M. New York City time on such Determination Date or as soon thereafter
  as rates first appear (but in no event later than 12:00 P.M. New York City
  time), as determined by the Calculation Agent. If no rate appears by 12:00
  P.M. New York City time on a Determination Date with respect to the Canadian
  bankers' acceptance rates, then the Canadian BA Rate will be determined as
  specified in clause (ii) below. "Reuters Screen Page CDOR" means the displays
  designated as Page CDOR on the Reuters Monitor Money Rates Service (or such
  other page as may replace Page CDOR on that service for the purpose of
  displaying the Canadian Dollar bankers' acceptance rates of major banks).

     (ii) With respect to a Determination Date on which no rate appears on
  Reuters Screen Page CDOR as specified in clause (i) above, the Calculation
  Agent will request each of four major banks in the Toronto interbank market,
  as selected by the Calculation Agent, to provide the Calculation Agent with
  its quotation for deposits in Canadian Dollars for a period of six months
  commencing on the related Determination Date to major banks in the Toronto
  interbank market at approximately 10:00 A.M. New York City time on such
  Determination Date and in a principal amount that is representative for a
  single transaction in such market at such time. If at least two such
  quotations are provided, the Canadian BA Rate determined on such Determination
  Date will be the arithmetic mean of such quotations. If fewer than two banks
  so selected by the Calculation Agent are quoting as mentioned in this
  sentence, the Canadian BA Rate will equal the average quotation for deposits
  in Canadian Dollars for a period of six months commencing on the related
  Determination Date of major banks in the Toronto interbank market in a
  principal amount that is representative for a single transaction in such
  market at such time as determined by the Calculation Agent.

  The "Determination Date" means the seventh scheduled NYSE Business Day prior
to the applicable Payment Date as determined by the Calculation Agent; provided,
however, if such day is not a Canadian Business Day, the Determination Date will
be the next succeeding scheduled Canadian Business Day. "NYSE Business Day"
means a day on which the New York Stock Exchange is open for trading. "Canadian
Business Day", as used in this Prospectus with respect to the Notes, means any
day on which commercial banks are open for business (including dealings in
foreign exchange and foreign currency deposits) in Toronto, Canada. The
Calculation Agent will determine which days are scheduled NYSE Business Days and
Canadian Business Days.

EVENTS OF DEFAULT AND ACCELERATION

  In case an Event of Default with respect to any Notes shall have occurred and
be continuing, the amount payable to a Holder of a Note upon any acceleration
permitted by the Notes, will equal: (i) the principal amount thereof, plus (ii)
an additional amount calculated as though the date of early repayment were a
Payment Date. If a bankruptcy proceeding is commenced in respect of the Company,
the claim of the Holder of a Note may be limited, under Section 502(b)(2) of
Title 11 of the United States Code, to the principal amount of the Note plus an
additional amount, if any, of contingent interest calculated as though the date
of the commencement of the proceeding were the maturity date of the Notes.

SECURITIES DEPOSITORY

  The Notes were issued in book-entry form and are represented by one fully
registered global security (the "Global Security"). The Global Security was
deposited with, or on behalf of, The Depository Trust Company, as Securities
Depository (the "Securities Depository"), registered in the name of the
Securities Depository or a nominee thereof. Unless and until it is exchanged in
whole or in part for Notes in definitive form, the Global Security may

                                       7
<PAGE>
 
not be transferred except as a whole by the Securities Depository to a nominee
of such Securities Depository or by a nominee of such Securities Depository to
such Securities Depository or another nominee of such Securities Depository or
by such Securities Depository or any such nominee to a successor of such
Securities Depository or a nominee of such successor.

  The Securities Depository has advised the Company as follows: the Securities
Depository is a limited-purpose trust company organized under the Banking Law of
the State of New York, a member of the Federal Reserve System, a "clearing
corporation" within the meaning of the New York Uniform Commercial Code, and a
"clearing agency" registered pursuant to the provisions of Section 17A of the
Exchange Act.  The Securities Depository was created to hold securities of its
participants ("Participants") and to facilitate the clearance and settlement of
securities transactions among its Participants in such securities through
electronic book-entry changes in accounts of the Participants, thereby
eliminating the need for physical movement of securities certificates. The
Securities Depository's Participants include securities brokers and dealers,
banks, trust companies, clearing corporations, and certain other organizations.
The Securities Depository is owned by a number of Participants and by the New
York Stock Exchange, Inc., the American Stock Exchange, Inc. and the National
Association of Securities Dealers, Inc.  Access to the Securities Depository
book-entry system is also available to others, such as banks, brokers, dealers
and trust companies that clear through or maintain a custodial relationship with
a Participant, either directly or indirectly ("Indirect Participants").

  Purchases of Notes must be made by or through Participants, which will receive
a credit on the records of the Securities Depository. The ownership interest of
each actual purchaser of each Note ("Beneficial Owner") is in turn to be
recorded on the Participants' or Indirect Participants' records. Beneficial
Owners will not receive written confirmation from the Securities Depository of
their purchase, but Beneficial Owners are expected to receive written
confirmations providing details of the transaction, as well as periodic
statements of their holdings, from the Participant or Indirect Participant
through which the Beneficial Owner entered into the transaction. Ownership of
beneficial interests in such Global Security will be shown on, and the transfer
of such ownership interests will be effected only through, records maintained by
the Securities Depository (with respect to interests of Participants) and on the
records of Participants (with respect to interests of persons held through
Participants). The laws of some states may require that certain purchasers of
securities take physical delivery of such securities in definitive form. Such
limits and such laws may impair the ability to own, transfer or pledge
beneficial interests in Global Securities.

  So long as the Securities Depository, or its nominee, is the registered owner
of the Global Security, the Securities Depository or its nominee, as the case
may be, will be considered the sole owner or Holder of the Notes represented by
such Global Security for all purposes under the Senior Indenture. Except as
provided below, Beneficial Owners in the Global Security will not be entitled to
have the Notes represented by such Global Security registered in their names,
will not receive or be entitled to receive physical delivery of the Notes in
definitive registered form and will not be considered the owners or Holders
thereof under the Senior Indenture. Accordingly, each Person owning a beneficial
interest in the Global Security must rely on the procedures of the Securities
Depository and, if such Person is not a Participant, on the procedures of the
Participant through which such Person owns its interest, to exercise any rights
of a Holder under the Senior Indenture. The Company understands that under
existing industry practices, in the event that the Company requests any action
of Holders or that an owner of a beneficial interest in such a Global Security
desires to give or take any action which a Holder is entitled to give or take
under the Senior Indenture, the Securities Depository would authorize the
Participants holding the relevant beneficial interests to give or take such
action, and such Participants would authorize Beneficial Owners owning through
such Participants to give or take such action or would otherwise act upon the
instructions of Beneficial Owners. Conveyance of notices and other
communications by the Securities Depository to Participants, by Participants to
Indirect Participants, and by Participants and Indirect Participants to
Beneficial Owners will be governed by arrangements among them, subject to any
statutory or regulatory requirements as may be in effect from time to time.

  Payment of the principal of, and amounts payable on any June Payment Date or
December Payment Date with respect to, Notes registered in the name of the
Securities Depository or its nominee will be made to the Securities Depository
or its nominee, as the case may be, as the Holder of the Global Security
representing such Notes. None

                                       8
<PAGE>
 
of the Company, the Trustee or any other agent of the Company or agent of the
Trustee will have any responsibility or liability for any aspect of the records
relating to or payments made on account of beneficial ownership interests or for
supervising or reviewing any records relating to such beneficial ownership
interests. The Company expects that the Securities Depository, upon receipt of
any payment of principal or amounts payable on any June Payment Date or December
Payment Date in respect of the Global Security, will credit the accounts of the
Participants with payment in amounts proportionate to their respective holdings
in principal amount of beneficial interest in such Global Security as shown on
the records of the Securities Depository. The Company also expects that payments
by Participants to Beneficial Owners will be governed by standing customer
instructions and customary practices, as is now the case with securities held
for the accounts of customers in bearer form or registered in "street name", and
will be the responsibility of such Participants.

  If (x) the Securities Depository is at any time unwilling or unable to
continue as Securities Depository and a successor depository is not appointed by
the Company within 60 days, (y) the Company executes and delivers to the Trustee
a Company Order to the effect that the Global Security shall be exchangeable or
(z) an Event of Default has occurred and is continuing with respect to the
Notes, the Global Security will be exchangeable for Notes in definitive form of
like tenor and of an equal aggregate principal amount, in denominations of
$1,000 and integral multiples thereof. Such definitive Notes shall be registered
in such name or names as the Securities Depository shall instruct the Trustee.
It is expected that such instructions may be based upon directions received by
the Securities Depository from Participants with respect to ownership of
beneficial interests in such Global Security.


                     THE CANADIAN BANKERS' ACCEPTANCE RATE

  Bankers' acceptances in Canada are a popular method of raising short-term
funding in Canada. Bankers' acceptances represent unconditional written orders
from a borrower instructing a bank to pay a certain amount of money on a
specified future date. Bankers' acceptances are generally issued in Canadian
$100,000 denominations, and are not guaranteed by the Canada Deposit
Corporation.

  The market for bankers' acceptances has grown from under 1 billion Canadian
Dollars in early 1975 to approximately 22 billion Canadian Dollars in 1993 and
is among the most liquid short-term securities markets in Canada.


                                  OTHER TERMS
GENERAL

  The Notes were issued as a series of Senior Debt Securities under the
Indenture (the "Senior Indenture"), dated as of April 1, 1983, as amended and
restated, between the Company and The Chase Manhattan Bank, formerly known as
Chemical Bank (successor by merger to Manufacturers Hanover Trust Company), as
trustee (the "Trustee"). A copy of the Senior Indenture is filed as an exhibit
to the registration statements relating to the Notes.  The following summaries
of certain provisions of the Senior Indenture do not purport to be complete and
are subject to, and qualified in their entirety by reference to, all provisions
of the Senior Indenture, including the definition therein of certain terms.

  The Senior Indenture provides that series of Senior Debt Securities may from
time to time be issued thereunder, without limitation as to aggregate principal
amount, in one or more series and upon such terms as the Company may establish
pursuant to the provisions thereof.

  The Senior Indenture provides that the Senior Indenture and the Notes are
governed by and construed in accordance with the laws of the State of New York.

                                       9
<PAGE>
 
  The Senior Indenture provides that the Company may issue Senior Debt
Securities with terms different from those of Senior Debt Securities previously
issued, and "reopen" a previously issued series of Senior Debt Securities and
issue additional Senior Debt Securities of such series.

  The Senior Debt Securities are unsecured and rank pari passu with all other
unsecured and unsubordinated indebtedness of the Company.  However, since the
Company is a holding company, the right of the Company, and hence the right of
creditors of the Company (including the Holders of Senior Debt Securities), to
participate in any distribution of the assets of any subsidiary upon its
liquidation or reorganization or otherwise is necessarily subject to the prior
claims of creditors of the subsidiary, except to the extent that claims of the
Company itself as a creditor of the subsidiary may be recognized.  In addition,
dividends, loans and advances from certain subsidiaries, including MLPF&S, to
the Company are restricted by net capital requirements under the Exchange Act
and under rules of certain exchanges and other regulatory bodies.

LIMITATIONS UPON LIENS

  The Company may not, and may not permit any Subsidiary to, create, assume,
incur or permit to exist any indebtedness for borrowed money secured by a
pledge, lien or other encumbrance (except for certain liens specifically
permitted by the Senior Indenture) on the Voting Stock owned directly or
indirectly by the Company of any Subsidiary (other than a Subsidiary which, at
the time of the incurrence of such secured indebtedness, has a net worth of less
than $3,000,000) without making effective provision whereby the Outstanding
Senior Debt Securities will be secured equally and ratably with such secured
indebtedness.

LIMITATION ON DISPOSITION OF VOTING STOCK OF, AND MERGER AND SALE OF ASSETS BY,
MLPF&S

  The Indenture provides that the Company may not sell, transfer or otherwise
dispose of any Voting Stock of MLPF&S or permit MLPF&S to issue, sell or
otherwise dispose of any of its Voting Stock, unless, after giving effect to any
such transaction, MLPF&S remains a Controlled Subsidiary (defined in the Senior
Indenture to mean a corporation more than 80% of the outstanding shares of
Voting Stock of which are owned directly or indirectly by the Company).  In
addition, the Company may not permit MLPF&S to (i) merge or consolidate, unless
the surviving company is a Controlled Subsidiary or (ii) convey or transfer its
properties and assets substantially as an entirety, except to one or more
Controlled Subsidiaries.

MERGER AND CONSOLIDATION

  The Indenture provides that the Company may consolidate or merge with or into
any other corporation, and the Company may sell, lease or convey all or
substantially all of its assets to any corporation, provided that (i) the
corporation (if other than the Company) formed by or resulting from any such
consolidation or merger or which shall have received such assets shall be a
corporation organized and existing under the laws of the United States of
America or a state thereof and shall assume payment of the principal of (and
premium, if any) and interest on the Senior Debt Securities and the performance
and observance of all of the covenants and conditions of the Senior Indenture to
be performed or observed by the Company, and (ii) the Company or such successor
corporation, as the case may be, shall not immediately thereafter be in default
under the Senior Indenture.

MODIFICATION AND WAIVER

  Modification and amendment of the Indenture may be effected by the Company and
the Trustee with the consent of the Holders of 66 2/3% in principal amount of
the Outstanding Senior Debt Securities of each series issued pursuant to such
indenture and affected thereby, provided that no such modification or amendment
may, without the consent of the Holder of each Outstanding Senior Debt Security
affected thereby, (a) change the Stated Maturity of the principal of, or any
installment of interest or Additional Amounts payable on, any Senior Debt
Security or any premium payable on the redemption thereof, or change the
Redemption Price; (b) reduce the principal amount of, or the interest or
Additional Amounts payable on, any Senior Debt Security or reduce the amount of
principal which

                                       10
<PAGE>
 
could be declared due and payable prior to the Stated Maturity; (c) change place
or currency of any payment of principal or any premium, interest or Additional
Amounts payable on any Senior Debt Security; (d) impair the right to institute
suit for the enforcement of any payment on or with respect to any Senior Debt
Security; (e) reduce the percentage in principal amount of the Outstanding
Senior Debt Securities of any series, the consent of whose Holders is required
to modify or amend the Indenture; or (f) modify the foregoing requirements or
reduce the percentage of Outstanding Senior Debt Securities necessary to waive
any past default to less than a majority.  No modification or amendment of the
Subordinated Indenture or any Subsequent Indenture for Subordinated Debt
Securities may adversely affect the rights of any holder of Senior Indebtedness
without the consent of such Holder.  Except with respect to certain fundamental
provisions, the Holders of at least a majority in principal amount of
Outstanding Senior Debt Securities of any series may, with respect to such
series, waive past defaults under the Indenture and waive compliance by the
Company with certain provisions thereof.

EVENTS OF DEFAULT

  Under the Senior Indenture, the following will be Events of Default with
respect to Senior Debt Securities of any series: (a) default in the payment of
any interest or Additional Amounts payable on any Senior Debt Security of that
series when due, continued for 30 days; (b) default in the payment of any
principal or premium, if any, on any Senior Debt Security of that series when
due; (c) default in the deposit of any sinking fund payment, when due, in
respect of any Senior Debt Security of that series; (d) default in the
performance of any other covenant of the Company contained in the Indenture for
the benefit of such series or in the Senior Debt Securities of such series,
continued for 60 days after written notice as provided in the Senior Indenture;
(e) certain events in bankruptcy, insolvency or reorganization; and (f) any
other Event of Default provided with respect to Senior Debt Securities of that
series.  The Trustee or the Holders of 25% in principal amount of the
Outstanding Senior Debt Securities of that series may declare the principal
amount (or such lesser amount as may be provided for in the Senior Debt
Securities of that series) of all Outstanding Senior Debt Securities of that
series and the interest due thereon and Additional Amounts payable in respect
thereof, if any to be due and payable immediately if an Event of Default with
respect to Senior Debt Securities of such series shall occur and be continuing
at the time of such declaration.  At any time after a declaration of
acceleration has been made with respect to Senior Debt Securities of any series
but before a judgment or decree for payment of money due has been obtained by
the Trustee, the Holders of a majority in principal amount of the Outstanding
Senior Debt Securities of that series may rescind any declaration of
acceleration and its consequences, if all payments due (other than those due as
a result of acceleration) have been made and all Events of Default have been
remedied or waived.  Any Event of Default with respect to Senior Debt Securities
of any series may be waived by the Holders of a majority in principal amount of
all Outstanding Senior Debt Securities of that series, except in a case of
failure to pay principal or premium, if any, or interest or Additional Amounts
payable on any Senior Debt Security of that series for which payment had not
been subsequently made or in respect of a covenant or provision which cannot be
modified or amended without the consent of the Holder of each Outstanding Senior
Debt Security of such series affected.

  The Holders of a majority in principal amount of the Outstanding Senior Debt
Securities of a series may 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 Senior Debt Securities of such
series, provided that such direction shall not be in conflict with any rule of
law or the Senior Indenture.  Before proceeding to exercise any right or power
under the Senior Indenture at the direction of such Holders, the Trustee shall
be entitled to receive from such Holders reasonable security or indemnity
against the costs, expenses and liabilities which might be incurred by it in
complying with any such direction.

  The Company is required to furnish to the Trustee annually a statement as to
the fulfillment by the Company of all of its obligations under the Senior
Indenture.

                           MERRILL LYNCH & CO., INC.
      GLOBAL BOND LINKED SECURITIES/sm/("GloBLS"/sm/) DUE DECEMBER 31, 1998
                            CURRENCY PROTECTED NOTES

  On February 22, 1993, Merrill Lynch & Co., Inc. (the "Company") issued
$30,000,000 aggregate principal amount of Global Bond Linked Securities due
December 31, 1998 (the "GloBLS" or the "Notes") in denominations of $1,000 and
integral multiples thereof. The Notes will mature and be repayable at 100% of
the principal amount thereof on December 31, 1998 (the "Maturity Date").
Payments will be payable with respect to the Notes semiannually on June 30 and
December 31 of each year, as described below ("June Payment Dates" and "December
Payment Dates", respectively), commencing June 30, 1993.

  The Company will make interest payments on the Notes each calendar year at a
per annum rate equal to the sum of (i) the Minimum Annual Payment Rate (3%), and
(ii) the Supplemental Annual Payment Rate. The "Supplemental Annual Payment
Rate" will equal the amount, if any, by which the price (expressed as a
percentage) of the Index Bund as of the applicable Determination Date exceeds
100.95% (the "Benchmark Price"). In no event, however, will the payments on the
Notes in any calendar year be at a rate less than the Minimum Annual Payment
Rate. The "Index Bund" will be the 7.125% Bundesanleihe due December 20, 2002
issued by the Federal Republic of Germany on December 29, 1992. If German
interest rates decline, the annual amount payable on the Notes is expected to
increase; if German interest rates increase, the annual amount payable on the
Notes is expected to decrease (although not less than a rate equal to the
Minimum Annual Payment Rate). For each $1,000 principal amount of Notes, the
Company will pay $15 of the total amount payable for each calendar year on the
June Payment Date and will pay the balance of the annual amount due on the Notes
for such year on the December Payment Date. The Notes are not subject to
redemption by the Holders or the Company prior to the Maturity Date.

  For information as to the calculation of the amount payable in any calendar
year see "Description of Notes" in this Prospectus.  FOR OTHER INFORMATION THAT
SHOULD BE CONSIDERED BY PROSPECTIVE INVESTORS, SEE "RISK FACTORS" BEGINNING ON
PAGE 3 OF THIS PROSPECTUS.

  Ownership of the Notes will be maintained in book-entry form by or through the
Securities Depository. Beneficial owners of the Notes will not have the right to
receive physical certificates evidencing their ownership except under the
limited circumstances described herein.

  The Notes have been listed on the New York Stock Exchange under the symbol
"MER DM".

  For the purpose of calculating the ratio of earnings to fixed charges,

debt expense, preferred stock dividend requirements of majority-owned
subsidiaries, and that portion of rentals estimated to be representative of the
interest factor.


                                  RISK FACTORS
SEMIANNUAL PAYMENTS

  If the Index Bund Price applicable to a December Payment Date does not exceed
the Benchmark Price, beneficial owners of the Notes will receive payments only
at the Minimum Annual Payment Rate payable with respect to the Notes, even if
the price of the Index Bund at some point since the preceding Determination Date
or issue date, as the case may be, exceeded the Benchmark Price.

                                       3
<PAGE>
 
  Beneficial owners will receive total annual payments on the Notes at a rate
equal to at least the Minimum Annual Payment Rate, and will be repaid 100% of
the principal amount of the Notes at the Maturity Date. The amount payable on
any December Payment Date is subject to the conditions described under
"Description of Notes--Semiannual Payments". A beneficial owner of the Notes may
receive payments with respect to the Notes at a rate equal to only the Minimum
Annual Payment Rate for each year at the times specified herein, and such
payments are below what the Company would pay as interest as of the date hereof
if the Company issued non-callable senior debt securities with a similar
maturity as that of the Notes. The return of principal at the Maturity Date and
the payment at a rate equal to the Minimum Annual Payment Rate with respect to
the Notes are not expected to reflect the full opportunity costs implied by
inflation or other factors relating to the time value of money.

  The amount payable on the Notes based on the Index Bund will not produce the
same return as if the Index Bund was purchased and held for a similar period
because of the following: (i) the Index Bund Price will not reflect any interest
payable on the Index Bund, (ii) interest and principal payable on the Notes will
be in U.S. Dollars while interest and principal payable on the Index Bund is
payable in Deutsche Marks and the U.S. Dollar value of such Deutsche Mark
payments may increase or decrease depending on the U.S. Dollar/Deutsche Mark
exchange rate, and (iii) the annual interest rate on the Index Bund is higher
than the Minimum Annual Payment Rate.

  Unlike a direct investment in the Index Bund, the principal and interest
payments on the Notes will be made in U.S. Dollars, and as such, the U.S. Dollar
value of such payments will not be subject to changes in Deutsche Mark/U.S.
Dollar exchange rates. Such exchange rate changes may have a direct effect on
the market demand for, and thus the price of, the Index Bund.

  The Senior Indenture provides that the Senior Indenture and the Notes are
governed by and construed in accordance with the laws of the State of New York.
Under present New York law the maximum rate of interest is 25% per annum on a
simple interest basis. This limit may not apply to notes in which $2,500,000 or
more has been invested. While the Company believes that New York law would be
given effect by a state or Federal court sitting outside of New York, state laws
frequently regulate the amount of interest that may be charged to and paid by a
borrower (including, in some cases, corporate borrowers). All payments under the
Notes (other than the return of principal) could be considered interest for the
purpose of state usury laws. The Company has covenanted for the benefit of the
Holders of the Notes, to the extent permitted by law, not to claim voluntarily
the benefits of any laws concerning usurious rates of interest against a Holder
of the Notes.

TRADING

  The Notes have been listed on the New York Stock Exchange under the symbol
"MER DM". It is expected that the secondary market for the Notes will be
affected by the creditworthiness of the Company and by a number of other
factors. It is possible to view the Notes as the economic equivalent of a debt
obligation plus a series of cash settlement options; however, there can be no
assurance that the Notes will not trade in the secondary market at a discount
from the aggregate value of such economic components, if such economic
components were valued and capable of being traded separately.

  The trading values of the Notes may be affected by a number of interrelated
factors, including those listed below. The following is the expected effect on
the trading value of the Notes of each of the factors listed below. The
following discussion of each separate factor generally assumes that all other
factors are held constant, although the actual interrelationship between certain
of such factors is complex.

  Price of the Index Bund. The trading value of the Notes is expected to depend
  significantly on the extent to which, if at all, the price of the Index Bund
  exceeds the Benchmark Price. If, however, Notes are sold at a time when the
  price of the Index Bund exceeds the Benchmark Price, the sale price may be at
  a discount from the amount expected to be payable to the beneficial owner if
  such price were to prevail until the next applicable

                                       4
<PAGE>
 
  Determination Date. Furthermore, the price at which a beneficial owner will be
  able to sell Notes prior to a December Payment Date may be at a discount,
  which could be substantial, from the principal amount thereof, if, at such
  time, the price of the Index Bund is below, equal to or not sufficiently above
  the Benchmark Price.

  Volatility of the Price of the Index Bund. If the volatility of the price of
  the Index Bund increases, the trading value of the Notes is expected to
  increase. If the volatility of the price of the Index Bund decreases, the
  trading value of the Notes is expected to decrease.

  Interest Rates. In general, if U.S. interest rates increase, the value of the
  Notes is expected to decrease. If U.S. interest rates decrease, the value of
  the Notes is generally expected to increase. In addition, German interest
  rates will affect the price of the Index Bund. In general, if German interest
  rates increase, the Index Bund price, and therefore the value of the Notes, is
  expected to decrease. If German interest rates decrease, the Index Bund price,
  and therefore the value of the Notes, is expected to increase.

  Time Remaining to December Payment Dates. The Notes may trade at a value above
  that which may be inferred from the level of interest rates and the price of
  the Index Bund. This difference will reflect a "time premium" due to
  expectations concerning the price of the Index Bund during the period prior to
  each December Payment Date. As the time remaining to each December Payment
  Date decreases, however, this time premium may decrease, thus decreasing the
  trading value of the Notes.

  Time Remaining to Maturity. As the number of remaining December Payment Dates
  decreases, the value of the remaining rights to receive payments based on the
  price of the Index Bund in excess of the Minimum Annual Payment Rate will
  decrease, thus decreasing the value of the Notes. Furthermore, as the time to
  the Maturity Date decreases, the value of the fixed payments (i.e., payments
  at the Minimum Annual Payment Rate and the payment of the principal amount at
  the maturity of the Notes) is expected to increase, thus increasing the value
  of the Notes. In addition, as the time to maturity decreases, the remaining
  term to maturity of the Index Bund will decrease. In general, a given change
  in German interest rates will generally affect German debt instruments with
  shorter maturities less than those with longer maturities.

OTHER CONSIDERATIONS

  It is suggested that prospective investors who consider purchasing the Notes
should reach an investment decision only after carefully considering the
suitability of the Notes in the light of their particular circumstances.

   Investors should also consider the tax consequences of investing in the Notes
and should consult their tax advisors.


                              DESCRIPTION OF NOTES
                                        
GENERAL

  The Notes were issued as a series of Senior Debt Securities under the Senior
Indenture, dated as of April 1, 1983, as amended and restated, which is more
fully described below. The Notes will mature, and the principal of the Notes
will be repayable at par, on December 31, 1998.

  The Notes are not subject to redemption prior to the Maturity Date by the
Company or at the option of any Holder. Upon the occurrence of an Event of
Default with respect to the Notes, however, Holders of the Notes or the Trustee
may accelerate the maturity of the Notes, as described under "Description of
Notes--Events of Default and Acceleration" and "Other Terms--Events of Default"
in this Prospectus.

                                       5
<PAGE>
 
  The Notes were issued in denominations of $1,000 and integral multiples
thereof.

SEMIANNUAL PAYMENTS

  The Company will make semiannual payments on the Notes each June 30 and
December 31 ("June Payment Dates" and "December Payment Dates", respectively),
as described below, to the persons in whose names the Notes are registered on
the next preceding June 29 or December 30, except as provided below.
Notwithstanding the foregoing, if it is known three Business Days prior to
December 31 that December 31 will not be a Business Day, the amount payable by
the Company with respect to such December Payment Date will be made on the
Business Day immediately preceding such December 31 to the persons in whose
names the Notes are registered on the second Business Day immediately preceding
such December 31 and the amount so paid will equal an amount as if interest had
accrued through December 31.

  For each calendar year, the Company will pay interest on the Notes at a rate
per annum equal to the sum of (i) the Minimum Annual Payment Rate (3%), and (ii)
the Supplemental Annual Payment Rate. The "Supplemental Annual Payment Rate"
equals the amount, if any, by which the price (expressed as a percentage) of the
Index Bund, determined as described below (the "Index Bund Price"), as of the
applicable Determination Date exceeds 100.95% (the "Benchmark Price") as
determined by the Calculation Agent. In no event, however, will the payments on
the Notes in any calendar year be at a rate less than the Minimum Annual Payment
Rate. For each $1,000 principal amount of the Notes, the Company will pay $15 of
the total amount payable for each calendar year on the June Payment Date, and
will pay the balance of the annual interest amount due on the Notes for such
year on the December Payment Date.

  State Street Bank and Trust Company is the calculation agent (the "Calculation
Agent") with respect to the Notes. All determinations made by the Calculation
Agent shall be at the sole discretion of the Calculation Agent and, in the
absence of manifest error, shall be conclusive for all purposes and binding on
the Company and the Holders of the Notes. All percentages resulting from any
calculation on the Notes will be rounded to the nearest one hundred-thousandth
of a percentage point, with five one-millionths of a percentage point rounded
upwards (e.g., 9.876545% (or .09876545) would be rounded to 9.87655% (or
 .0987655)), and all dollar amounts used in or resulting from such calculation
will be rounded to the nearest cent (with one-half cent being rounded upwards).


  If the Index Bund Price applicable to a December Payment Date does not exceed
the Benchmark Price, Holders of the Notes will receive payments which reflect
only the Minimum Annual Payment Rate payable with respect to the Notes for the
calendar year containing such December Payment Date, even if the price of the
Index Bund at some point since the preceding Determination Date or issue date,
as the case may be, exceeded the Benchmark Price.

INDEX BUND PRICE

  The Index Bund Price is the arithmetic mean of the bid prices for the 7.125%
Bundesanleihe due December 20, 2002 issued by the Federal Republic of Germany on
December 29, 1992 (the "Index Bund"), expressed as a percentage of the principal
amount, as of 9:30 A.M. New York City time on the applicable Determination Date,
of three leading dealers in Bundesanleihen selected by the Calculation Agent.
The "Determination Date" means the seventh scheduled NYSE Business Day (as
defined below) prior to the applicable December Payment Date. If three such bid
prices are not available on such seventh scheduled NYSE Business Day, the
Determination Date will be the sixth scheduled NYSE Business Day preceding the
applicable December Payment Date. If the Calculation Agent cannot obtain three
bid prices from leading dealers for Bundesanleihen on the sixth scheduled NYSE
Business Day preceding the applicable December Payment Date, then the Index Bund
Price will equal the official price expressed as a percentage reported by the
Frankfurt Stock Exchange for the Index Bund as a result of the official price
fixing on the Frankfurt Stock Exchange on such sixth scheduled NYSE Business Day
preceding the applicable December Payment Date. If no official price is fixed on
the Frankfurt Stock Exchange on such sixth scheduled NYSE Business Day, then the
Index Bund Price will equal the bid price determined by the Calculation Agent on
such sixth scheduled NYSE Business Day based on then current market conditions,
including the last price at which the Index Bund was offered or sold. The bid
prices solicited by the Calculation Agent will be for an amount that is
representative of a single transaction in the market at the applicable time and
will not include accrued but unpaid interest on the Index Bund. "NYSE Business
Day" means a day on which the New York Stock Exchange is open for trading and
the Calculation Agent will determine which days are scheduled NYSE Business
Days.

  A potential investor should review the historical performance of the Index
Bund. The historical performance of the Index Bund should not be taken as an
indication of future performance, and no assurance can be given that the Index
Bund will increase sufficiently to cause the beneficial owners of the Notes to
receive an amount in excess of principal and the Minimum Annual Payment Rate at
the maturity of the Notes or the Minimum Annual Payment Rate in any prior year.

EVENTS OF DEFAULT AND ACCELERATION

   In case an Event of Default with respect to any Notes shall have occurred and
be continuing, the amount payable to a Holder of a Note upon any acceleration
permitted by the Notes, will equal: (i) the principal amount thereof, plus (ii)
an additional amount calculated as though the date of early repayment were a
December Payment Date and prorated through such date of early repayment in the
same manner as the amount payable on the December 1993 payment date was
prorated. If a bankruptcy proceeding is commenced in respect of the Company, the
claim of the Holder of a Note may be limited, under Section 502(b)(2) of Title
11 of the United States Code, to the principal amount of the Note plus an
additional amount, if any, of contingent interest calculated as though the date
of the commencement of the proceeding were the maturity date of the Notes.

SECURITIES DEPOSITORY

  The Notes were issued in book-entry form, and are represented by one
registered global security (the "Global Security"). The Global Security was
deposited with, or on behalf of, The Depository Trust Company, as Securities
Depository (the "Securities Depository"), registered in the name of the
Securities Depository or a nominee thereof. Unless and until it is exchanged in
whole or in part for Securities in definitive form, the Global Security may not
be transferred except as a whole by the Securities Depository to a nominee of
such Securities Depository or by a nominee of such Securities Depository to such
Securities Depository or another nominee of such Securities Depository or by
such Securities Depository or any such nominee to a successor of such Securities
Depository or a nominee of such successor.

  The Securities Depository has advised the Company as follows: The Securities
Depository is a limited-purpose trust company organized under the Banking Law of
the State of New York, a member of the Federal Reserve System, a "clearing
corporation" within the meaning of the New York Uniform Commercial Code, and a
"clearing agency" registered pursuant to the provisions of Section 17A of the
Exchange Act.  The Securities Depository was created to hold securities of its
participants ("Participants") and to facilitate the clearance and settlement of
securities transactions among its Participants in such securities through
electronic book-entry changes in accounts of the Participants, thereby
eliminating the need for physical movement of securities certificates. The
Securities Depository's Participants include securities brokers and dealers,
banks, trust companies, clearing corporations, and certain other organizations.
The Securities Depository is owned by a number of Participants and by the New
York Stock Exchange, Inc., the American Stock Exchange, Inc. and the National
Association of Securities Dealers, Inc. The Underwriter (as hereinafter defined)
is a Participant. Access to the Securities Depository book-entry system is also
available to others, such as banks, brokers, dealers and trust companies that
clear through or maintain a custodial relationship with a Participant, either
directly or indirectly ("Indirect Participants").

  Purchases of Notes must be made by or through Participants, which will receive
a credit on the records of the Securities Depository. The ownership interest of
each actual purchaser of each Note ("Beneficial Owner") is in turn to be
recorded on the Participants' or Indirect Participants' records.  Beneficial
Owners will not receive written confirmation from the Securities Depository of
their purchase, but Beneficial Owners are expected to receive written
confirmations providing details of the transaction, as well as periodic
statements of their holdings, from the Participant or Indirect Participant
through which the Beneficial Owner entered into the transaction. Ownership of
beneficial interests in such Global Security will be shown on, and the transfer
of such ownership interests will be effected only through, records maintained by
the Securities Depository (with respect to interests of Participants) and on the
records of Participants (with respect to interests of persons held through
Participants). The laws of some states may require that certain purchasers of
securities take physical delivery of such securities in definitive form. Such
limits and such laws may impair the ability to own, transfer or pledge
beneficial interests in Global Securities.

  So long as the Securities Depository, or its nominee, is the registered owner
of the Global Security, the Securities Depository or its nominee, as the case
may be, will be considered the sole owner or Holder of the Notes represented by
such Global Security for all purposes under the Senior Indenture. Except as
provided below, Beneficial Owners in the Global Security will not be entitled to
have the Notes represented by such Global Security registered in their

                                       9
<PAGE>
 
names, will not receive or be entitled to receive physical delivery of the Notes
in definitive registered form and will not be considered the owners or Holders
thereof under the Senior Indenture. Accordingly, each Person owning a beneficial
interest in the Global Security must rely on the procedures of the Securities
Depository and, if such Person is not a Participant, on the procedures of the
Participant through which such Person owns its interest, to exercise any rights
of a Holder under the Senior Indenture. The Company understands that under
existing industry practices, in the event that the Company requests any action
of Holders or that an owner of a beneficial interest in such a Global Security
desires to give or take any action which a Holder is entitled to give or take
under the Senior Indenture, the Securities Depository would authorize the
Participants holding the relevant beneficial interests to give or take such
action, and such Participants would authorize Beneficial Owners owning through
such Participants to give or take such action or would otherwise act upon the
instructions of beneficial owners. Conveyance of notices and other
communications by the Securities Depository to Participants, by Participants to
Indirect Participants, and by Participants and Indirect Participants to
Beneficial Owners will be governed by arrangements among them, subject to any
statutory or regulatory requirements as may be in effect from time to time.

  Payment of the principal of, and amounts payable on any June Payment Date or
December Payment Date with respect to, Notes registered in the name of the
Securities Depository or its nominee will be made to the Securities Depository
or its nominee, as the case may be, as the Holder of the Global Security
representing such Notes. None of the Company, the Trustee or any other agent of
the Company or agent of the Trustee will have any responsibility or liability
for any aspect of the records relating to or payments made on account of
beneficial ownership interests or for supervising or reviewing any records
relating to such beneficial ownership interests. The Company expects that the
Securities Depository, upon receipt of any payment of principal or amounts
payable on any June Payment Date or December Payment Date in respect of the
Global Security, will credit the accounts of the Participants with payment in
amounts proportionate to their respective holdings in principal amount of
beneficial interest in such Global Security as shown on the records of the
Securities Depository. The Company also expects that payments by Participants to
Beneficial Owners will be governed by standing customer instructions and
customary practices, as is now the case with securities held for the accounts of
customers in bearer form or registered in "street name", and will be the
responsibility of such Participants.

  If (x) the Securities Depository is at any time unwilling or unable to
continue as Securities Depository and a successor depository is not appointed by
the Company within 60 days, (y) the Company executes and delivers to the Trustee
a Company Order to the effect that the Global Security shall be exchangeable or
(z) an Event of Default has occurred and is continuing with respect to the
Notes, the Global Security will be exchangeable for Notes in definitive form of
like tenor and of an equal aggregate principal amount, in denominations of
$1,000 and integral multiples thereof. Such definitive Notes shall be registered
in such name or names as the Securities Depository shall instruct the Trustee.
It is expected that such instructions may be based upon directions received by
the Securities Depository from Participants with respect to ownership of
beneficial interests in such Global Security.


                   THE GERMAN BOND MARKET AND THE INDEX BUND

  The following discussion of the German bond market is based upon information
available as of the end of September 1992.  The Deutsche Mark-denominated fixed
income market is the third largest in the world, exceeded in size only by those
of the U.S. Dollar and Japanese Yen. As of the end of September 1992, the total
nominal amount of Deutsche Mark-denominated fixed income debt outstanding was
over DM 1.889 trillion (or U.S. $1.18 trillion assuming an exchange rate of
DM/U.S. $1.60) (Source: Bundesbank). Bundesanleihen ("Bunds") are debt
securities issued by the Federal Republic of Germany and are backed by its full
faith and credit. Bunds account for approximately 75% of the debt of the Federal
Republic of Germany and approximately 30% of all fixed income debt denominated
in Deutsche Marks as of the end of September 1992. Bundesanleihen are
principally traded in the over-the-counter market in Germany and are also listed
on eight exchanges in Germany, including the Frankfurt Exchange.

                                       10
<PAGE>
 
  The Index Bund was originally issued on December 29, 1992 and is not
redeemable prior to its stated maturity. Because the Index Bund had a maturity
of ten years when it was originally issued, the time remaining to such maturity
will necessarily decline over time. As the time remaining to maturity declines
on the Index Bund, the Index Bund price will be affected.

  A potential investor should review the historical performance of the Index
Bund.  The historical performance of the Index Bund should not be taken as an
indication of future performance, and no assurance can be given that the Index
Bund will increase sufficiently to cause the beneficial owners of the Notes to
receive an amount in excess of the principal amount at the maturity of the
Notes.


                                  OTHER TERMS
GENERAL

  The Notes were issued as a series of Senior Debt Securities under the
Indenture (the "Senior Indenture"), dated as of April 1, 1983, as amended and
restated, between the Company and The Chase Manhattan Bank, formerly known as
Chemical Bank (successor by merger to Manufacturers Hanover Trust Company), as
trustee (the "Trustee"). A copy of the Senior Indenture is filed as an exhibit
to the registration statements relating to the Notes. The following summaries of
certain provisions of the Senior Indenture do not purport to be complete and are
subject to, and qualified in their entirety by reference to, all provisions of
the Senior Indenture, including the definition therein of certain terms.

  The Senior Indenture provides that series of Senior Debt Securities may from
time to time be issued thereunder, without limitation as to aggregate principal
amount, in one or more series and upon such terms as the Company may establish
pursuant to the provisions thereof.

  The Senior Indenture provides that the Senior Indenture and the Notes are
governed by and construed in accordance with the laws of the State of New York.

  The Senior Indenture provides that the Company may issue Senior Debt
Securities with terms different from those of Senior Debt Securities previously
issued, and "reopen" a previously issued series of Senior Debt Securities and
issue additional Senior Debt Securities of such series.

  The Senior Debt Securities are unsecured and rank pari passu with all other
unsecured and unsubordinated indebtedness of the Company.  However, since the
Company is a holding company, the right of the Company, and hence the right of
creditors of the Company (including the Holders of Senior Debt Securities), to
participate in any distribution of the assets of any subsidiary upon its
liquidation or reorganization or otherwise is necessarily subject to the prior
claims of creditors of the subsidiary, except to the extent that claims of the
Company itself as a creditor of the subsidiary may be recognized.  In addition,
dividends, loans and advances from certain subsidiaries, including MLPF&S, to
the Company are restricted by net capital requirements under the Exchange Act
and under rules of certain exchanges and other regulatory bodies.

LIMITATIONS UPON LIENS

  The Company may not, and may not permit any Subsidiary to, create, assume,
incur or permit to exist any indebtedness for borrowed money secured by a
pledge, lien or other encumbrance (except for certain liens specifically
permitted by the Senior Indenture) on the Voting Stock owned directly or
indirectly by the Company of any Subsidiary (other than a Subsidiary which, at
the time of the incurrence of such secured indebtedness, has a net worth of less
than $3,000,000) without making effective provision whereby the Outstanding
Senior Debt Securities will be secured equally and ratably with such secured
indebtedness.

                                       11
<PAGE>
 
LIMITATION ON DISPOSITION OF VOTING STOCK OF, AND MERGER AND SALE OF ASSETS BY,
MLPF&S

  The Indenture provides that the Company may not sell, transfer or otherwise
dispose of any Voting Stock of MLPF&S or permit MLPF&S to issue, sell or
otherwise dispose of any of its Voting Stock, unless, after giving effect to any
such transaction, MLPF&S remains a Controlled Subsidiary (defined in the Senior
Indenture to mean a corporation more than 80% of the outstanding shares of
Voting Stock of which are owned directly or indirectly by the Company).  In
addition, the Company may not permit MLPF&S to (i) merge or consolidate, unless
the surviving company is a Controlled Subsidiary or (ii) convey or transfer its
properties and assets substantially as an entirety, except to one or more
Controlled Subsidiaries.

MERGER AND CONSOLIDATION

  The Indenture provides that the Company may consolidate or merge with or into
any other corporation, and the Company may sell, lease or convey all or
substantially all of its assets to any corporation, provided that (i) the
corporation (if other than the Company) formed by or resulting from any such
consolidation or merger or which shall have received such assets shall be a
corporation organized and existing under the laws of the United States of
America or a state thereof and shall assume payment of the principal of (and
premium, if any) and interest on the Senior Debt Securities and the performance
and observance of all of the covenants and conditions of the Senior Indenture to
be performed or observed by the Company, and (ii) the Company or such successor
corporation, as the case may be, shall not immediately thereafter be in default
under the Senior Indenture.

MODIFICATION AND WAIVER

  Modification and amendment of the Indenture may be effected by the Company and
the Trustee with the consent of the Holders of 66 2/3% in principal amount of
the Outstanding Senior Debt Securities of each series issued pursuant to such
indenture and affected thereby, provided that no such modification or amendment
may, without the consent of the Holder of each Outstanding Senior Debt Security
affected thereby, (a) change the Stated Maturity of the principal of, or any
installment of interest or Additional Amounts payable on, any Senior Debt
Security or any premium payable on the redemption thereof, or change the
Redemption Price; (b) reduce the principal amount of, or the interest or
Additional Amounts payable on, any Senior Debt Security or reduce the amount of
principal which could be declared due and payable prior to the Stated Maturity;
(c) change place or currency of any payment of principal or any premium,
interest or Additional Amounts payable on any Senior Debt Security; (d) impair
the right to institute suit for the enforcement of any payment on or with
respect to any Senior Debt Security; (e) reduce the percentage in principal
amount of the Outstanding Senior Debt Securities of any series, the consent of
whose Holders is required to modify or amend the Indenture; or (f) modify the
foregoing requirements or reduce the percentage of Outstanding Senior Debt
Securities necessary to waive any past default to less than a majority.  No
modification or amendment of the Subordinated Indenture or any Subsequent
Indenture for Subordinated Debt Securities may adversely affect the rights of
any holder of Senior Indebtedness without the consent of such Holder.  Except
with respect to certain fundamental provisions, the Holders of at least a
majority in principal amount of Outstanding Senior Debt Securities of any series
may, with respect to such series, waive past defaults under the Indenture and
waive compliance by the Company with certain provisions thereof.

EVENTS OF DEFAULT

  Under the Senior Indenture, the following will be Events of Default with
respect to Senior Debt Securities of any series: (a) default in the payment of
any interest or Additional Amounts payable on any Senior Debt Security of that
series when due, continued for 30 days; (b) default in the payment of any
principal or premium, if any, on any Senior Debt Security of that series when
due; (c) default in the deposit of any sinking fund payment, when due, in
respect of any Senior Debt Security of that series; (d) default in the
performance of any other covenant of the Company contained in the Indenture for
the benefit of such series or in the Senior Debt Securities of such series,
continued for 60 days after written notice as provided in the Senior Indenture;
(e) certain events in bankruptcy, insolvency or reorganization; and (f) any
other Event of Default provided with respect to Senior Debt Securities of

                                       12
<PAGE>
 
that series.  The Trustee or the Holders of 25% in principal amount of the
Outstanding Senior Debt Securities of that series may declare the principal
amount (or such lesser amount as may be provided for in the Senior Debt
Securities of that series) of all Outstanding Senior Debt Securities of that
series and the interest due thereon and Additional Amounts payable in respect
thereof, if any to be due and payable immediately if an Event of Default with
respect to Senior Debt Securities of such series shall occur and be continuing
at the time of such declaration.  At any time after a declaration of
acceleration has been made with respect to Senior Debt Securities of any series
but before a judgment or decree for payment of money due has been obtained by
the Trustee, the Holders of a majority in principal amount of the Outstanding
Senior Debt Securities of that series may rescind any declaration of
acceleration and its consequences, if all payments due (other than those due as
a result of acceleration) have been made and all Events of Default have been
remedied or waived.  Any Event of Default with respect to Senior Debt Securities
of any series may be waived by the Holders of a majority in principal amount of
all Outstanding Senior Debt Securities of that series, except in a case of
failure to pay principal or premium, if any, or interest or Additional Amounts
payable on any Senior Debt Security of that series for which payment had not
been subsequently made or in respect of a covenant or provision which cannot be
modified or amended without the consent of the Holder of each Outstanding Senior
Debt Security of such series affected.

  The Holders of a majority in principal amount of the Outstanding Senior Debt
Securities of a series may 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 Senior Debt Securities of such
series, provided that such direction shall not be in conflict with any rule of
law or the Senior Indenture.  Before proceeding to exercise any right or power
under the Senior Indenture at the direction of such Holders, the Trustee shall
be entitled to receive from such Holders reasonable security or indemnity
against the costs, expenses and liabilities which might be incurred by it in
complying with any such direction.

  The Company is required to furnish to the Trustee annually a statement as to
the fulfillment by the Company of all of its obligations under the Senior
Indenture.

  The consolidated financial statements and related financial statement
schedules of the Company and its subsidiaries included or incorporated by
reference in the Company's 1996 Annual Report on Form 10-K, and incorporated by

                           MERRILL LYNCH & CO., INC.
              AMEX HONG KONG 30 INDEX* EQUITY PARTICIPATION NOTES
                             DUE FEBRUARY 16, 1999

  On February 7, 1996, Merrill Lynch & Co., Inc. (the "Company") issued
$45,000,000 aggregate principal amount of AMEX Hong Kong 30 Index Equity
Participation Notes due February 16, 1999 (the "Notes" or the "Securities").  As
of the date of this Prospectus, $45,000,000 aggregate principal amount of
Securities remain outstanding.  The Securities were issued in denominations of
$1,000 and integral multiples thereof, will bear no periodic payments of
interest and will mature on February 16, 1999. At maturity, a beneficial owner
of a Note will be entitled to receive, with respect to each Note, the principal
amount thereof plus an interest payment (the "Supplemental Redemption Amount")
based on the percentage increase, if any, in the AMEX Hong Kong 30 Index (the
"Index") over the Benchmark Index Value. The Supplemental Redemption Amount will
in no event be less than zero or more than $1,000 per $1,000 principal amount of
Notes, representing a maximum annualized rate of return of 24.28% compounded
semi-annually over a term of three years. The Notes are not redeemable or
callable by the Company prior to maturity. While at maturity a beneficial owner
of a Note will receive the principal amount of such Note plus the Supplemental
Redemption Amount, if any, there will be no other payment of interest, periodic
or otherwise.

  The Supplemental Redemption Amount payable with respect to a Note at maturity
will equal the product of (A) the principal amount of the applicable Note, and
(B) the percentage increase from the Benchmark Index Value to the Ending Index
Value. The Benchmark Index Value equals 664.83 and was determined as described
herein. The closing value of the Index on the date of this Prospectus was
579.79, and the Benchmark Index Value exceeds such closing value by 14.67%. The
Ending Index Value, as more particularly described herein, will be the average
(arithmetic mean) of the closing values of the Index on certain days, or, if
certain events occur, the closing value of the Index on a single day prior to
the maturity of the Notes.

  FOR INFORMATION AS TO THE CALCULATION OF THE SUPPLEMENTAL REDEMPTION AMOUNT
WHICH WILL BE PAID AT MATURITY, THE CALCULATION AND THE COMPOSITION OF THE
INDEX, SEE "DESCRIPTION OF NOTES" AND "THE INDEX", RESPECTIVELY, IN THIS
PROSPECTUS. FOR OTHER INFORMATION THAT SHOULD BE CONSIDERED BY PROSPECTIVE
INVESTORS, SEE "RISK FACTORS" BEGINNING ON PAGE 3 OF THIS PROSPECTUS.

  Ownership of the Notes will be maintained in book-entry form by or through the
Depository (as hereinafter defined). Beneficial owners of the Notes will not
have the right to receive physical certificates evidencing their ownership
except under the limited circumstances described herein.

  The Notes have been listed on the American Stock Exchange (the "AMEX") under
the symbol "HKN.A".

                                  RISK FACTORS

PAYMENT AT MATURITY

  Benchmark Index Value will Exceed Value of Index on the Pricing Date. The
Benchmark Index Value exceeded the closing value of the Index on the Pricing
Date by 14.67%. Investors should be aware that if the Ending Index Value does
not exceed the closing value of the Index on the Pricing Date by more than
14.67%, beneficial owners of the Notes will receive only the principal amount
thereof.

                                       3
<PAGE>
 
  Yield may be Below Market Interest Rates on the Pricing Date. A beneficial
owner of the Notes may receive no Supplemental Redemption Amount at maturity, or
a Supplemental Redemption Amount that is below what the Company would pay as
interest as of the Pricing Date if the Company issued non-callable senior debt
securities with a similar maturity as that of the Notes. The return of principal
of the Notes at maturity and the payment of the Supplemental Redemption Amount,
if any, may not reflect the full opportunity costs implied by inflation or other
factors relating to the time value of money.

  Limitation of Supplemental Redemption Amount. Because the Supplemental
Redemption Amount will not exceed $1,000 per $1,000 principal amount of Notes,
beneficial owners of Notes will not benefit from Index increases in excess of
approximately 229% of the closing value of the Index on the Pricing Date (the
"Maximum Index Value"). In no event will the Supplemental Redemption Amount
exceed $1,000 per $1,000 principal amount of Notes.

  Yield on Notes will not Reflect Dividends. The Index does not reflect the
payment of dividends on the stocks underlying it and therefore the yield based
on the Index to the maturity of the Notes will not produce the same yield as if
such underlying stocks were purchased and held for a similar period.

  State Law Limit on Interest Paid. Because the Senior Indenture provides that
the Notes are governed by and construed in accordance with the laws of New York,
certain usury laws of New York State may apply. Under present New York law, the
maximum rate of interest is 25% per annum on a simple interest basis. This limit
may not apply to Notes in which $2,500,000 or more has been invested. While the
Company believes that New York law would be given effect by a state or Federal
court sitting outside of New York, state laws frequently regulate the amount of
interest that may be charged to and paid by a borrower (including, in some
cases, corporate borrowers). It is suggested that prospective investors consult
their personal advisors with respect to the applicability of such laws. The
Company has covenanted for the benefit of the Holders of the Notes, to the
extent permitted by law, not to claim voluntarily the benefits of any laws
concerning usurious rates of interest against a Holder of the Notes.

TRADING

  The Notes have been listed on the American Stock Exchange. It is expected that
the secondary market for the Notes will be affected by the creditworthiness of
the Company and by a number of other factors.

  The trading value of the Notes is expected to depend substantially on the
extent of the appreciation, if any, of the Index over the Benchmark Index Value.
See "The Index-Historical Data on the Index" in this Prospectus for historical
values of the Index. If, however, Notes are sold prior to the maturity date at a
time when the Index exceeds the Benchmark Index Value, the sale price may be at
a substantial discount from the amount expected to be payable to the beneficial
owner if such excess of the Index over the Benchmark Index Value were to prevail
until maturity of the Notes because of the possible fluctuation of the Index
between the time of such sale and the time that the Ending Index Value is
determined. Furthermore, the price at which a beneficial owner will be able to
sell Notes prior to maturity may be at a discount, which could be substantial,
from the principal amount thereof, if, at such time, the Index is below, equal
to, or not sufficiently above the Benchmark Index Value. The limitation that the
Supplemental Redemption Amount will not exceed $1,000 per $1,000 principal
amount of Notes may adversely affect the secondary market value of the Notes and
such adverse effect could occur even if the value of the Index is below the
Maximum Index Value. A discount could also result from rising interest rates.

  In addition to the value of the Index, the trading value of the Notes may be
affected by a number of interrelated factors, including the creditworthiness of
the Company and those factors listed below. The relationship among these factors
is complex, including how these factors affect the relative value of the
principal amount of the Notes to be repaid at maturity and the value of the
Supplemental Redemption Amount. Accordingly, investors should be aware that
factors other than the level of the Index are likely to affect the Notes'
trading value. The expected effect on the trading value of the Notes of each of
the factors listed below, assuming in each case that all other factors are held
constant, is as follows:

                                       4
<PAGE>
 
     Interest Rates. In general, if U.S. interest rates increase, the trading
  value of the Notes is expected to decrease. If U.S. interest rates decrease,
  the trading value of the Notes is expected to increase. If interest rates in
  Hong Kong increase, the trading value of the Notes is expected to increase;
  however, increased Hong Kong interest rates may adversely affect the economy
  of Hong Kong and, in turn, the Index, and the trading value of the Notes could
  then be expected to decrease. If interest rates in Hong Kong decrease, the
  trading value of the Notes is expected to decrease; however, decreased Hong
  Kong interest rates may favorably affect the economy of Hong Kong and, in
  turn, the Index, and consequently, the trading value of the Notes could then
  be expected to increase.

     Volatility of the Index. If the volatility of the Index increases, the
  trading value of the Notes is expected to increase. If the volatility of the
  Index decreases, the trading value of the Notes is expected to decrease.

     Time Remaining to Maturity. The Notes may trade at a value above that which
  may be inferred from the level of interest rates and the Index. This
  difference will reflect a "time premium" due to expectations concerning the
  value of the Index during the period prior to maturity of the Notes. As the
  time remaining to maturity of the Notes decreases, however, this time premium
  is expected to decrease, thus decreasing the trading value of the Notes. In
  addition, the price at which a beneficial owner may be able to sell Notes
  prior to maturity may be at a discount, which may be substantial, from the
  principal amount of the Notes if the value of the Index is below, equal to, or
  not sufficiently above the Benchmark Index Value.

     Dividend Rates in Hong Kong. If dividend rates on the stocks comprising the
  Index increase, the value of the Notes is expected to decrease. Conversely, if
  dividend rates on the stocks comprising the Index decrease, the value of the
  Notes is expected to increase. However, in general, rising corporate dividend
  rates in Hong Kong may increase the value of the Index and, in turn, increase
  the value of the Notes. Conversely, falling dividend rates in Hong Kong may
  decrease the value of the Index and, in turn, decrease the value of the Notes.

     Hong Kong Dollar/U.S. Dollar Exchange Rates. The Supplemental Redemption
  Amount is based on a given level of the Index and will not be affected by
  changes in the Hong Kong dollar/U.S. dollar exchange rate. However, a number
  of economic factors, including the Hong Kong dollar/U.S. dollar exchange rate,
  could affect the value of the Underlying Stocks and, therefore, the value of
  the Index.

  The impact of the factors specified above, excluding the value of the Index,
may offset, partially or in whole, any increase in the trading value of the
Notes that is attributable to an increase in the value of the Index. For
example, an increase in U.S. interest rates may cause the Notes to trade at a
discount from their initial offering price, even if the Index has appreciated
significantly. In general, assuming all relevant factors are held constant, the
effect on the trading value of the Notes of a given change in interest rates,
Index volatility and/or dividend rates of stocks comprising the Index is
expected to be less if it occurs later in the term of the Notes than if it
occurs earlier in the term of the Notes. The effect on the trading value of the
Notes of a given appreciation of the Index in excess of the Benchmark Index
Value is expected to be greater if it occurs later in the term of the Notes than
if it occurs earlier in the term of the Notes, assuming all other relevant
factors are held constant.

THE INDEX

  The stocks underlying the Index have been issued by companies organized in
Hong Kong. The prices of such Underlying Stocks will be affected by foreign
political, economic and other developments.

  The Hong Kong Stock Exchange has adopted certain measures intended to prevent
any extreme short-term price fluctuations resulting from order imbalances or
market volatility. Where the Hong Kong Stock Exchange considers it necessary for
the protection of the investor or the maintenance of an orderly market, it may
at any time suspend dealings in any securities or cancel the listing of any
securities in such circumstances and subject to such conditions as it thinks
fit, whether requested by the listed issuer or not. The Hong Kong Stock Exchange
may also do so when: (1) an issuer fails, in a manner which the Hong Kong Stock
Exchange considers material, to comply with the Hong

                                       5
<PAGE>
 
Kong Stock Exchange Listing Rules or its Listing Agreements; or (2) the Hong
Kong Stock Exchange considers there are insufficient securities in the hands of
the public; or (3) the Hong Kong Stock Exchange considers that the listed issuer
does not have a sufficient level of operations or sufficient assets to warrant
the continued listing of the issuer's securities; or (4) the Hong Kong Stock
Exchange considers that the issuer or its business is no longer suitable for
listing. Investors should also be aware that the Hong Kong Stock Exchange may
suspend the trading of individual stocks in certain limited and extraordinary
circumstances, until certain price-sensitive information has been disclosed to
the public. Since the stocks underlying the Index are traded on the Hong Kong
Stock Exchange, changes in the Index may be affected by suspensions of trading
generally or of one or more of the stocks underlying the Index, which
limitations may, in turn, adversely affect the value of the Notes.

IMPORTANT CONSIDERATIONS RELATING TO HONG KONG

  Investors should realize that the value of the Index, and therefore the
potential Supplemental Redemption Amount, if any, may be adversely affected by
political, economic or social instability, developments and changes in law or
regulations, particularly in Hong Kong and the People's Republic of China
("China"). Certain of these factors are discussed below.

  In December 1984, Great Britain and China signed an agreement (the "Sino-
British Accord") under which Hong Kong will revert to Chinese sovereignty
effective July 1, 1997. Although China has committed by treaty to preserve for
50 years the economic and social freedoms currently enjoyed in Hong Kong, the
continuation of the economic system in Hong Kong after the reversion will be
affected by the Chinese government. Any increase in uncertainty as to the future
economic and political status of Hong Kong could have a material adverse effect
on the economy of Hong Kong and the Index.

  The Sino-British Accord provides that the basic policies of China regarding
Hong Kong and the elaboration of these policies in the Sino-British Accord will
be stipulated by the National People's Congress of China in a Basic Law of the
Hong Kong Special Administrative Region (the "Hong Kong SAR") (the "Basic Law").
The Basic Law was finalized in February 1990 and adopted by the National
People's Congress on April 4, 1990. The Basic Law provides that the Chief
Executive of the Hong Kong SAR will be recommended by a committee composed of
Hong Kong residents representing a broad spectrum of distinct constituencies,
such as industry, labor and the various professions, and appointed by the
government of China. The power of amendment of the Basic Law is vested in the
National People's Congress of China. The Basic Law provides that the Hong Kong
dollar will remain the legal tender in the Hong Kong SAR after the transfer of
sovereignty. It also provides that no exchange control policies will be applied
in the Hong Kong SAR and that the Hong Kong dollar will remain freely
convertible.

  In the past, the prices of shares on the HKSE and Hong Kong property market
values have experienced substantial fluctuations in response to political
developments affecting China and relations between China and the United Kingdom.
Although China has agreed by treaty that the Hong Kong SAR will have a high
degree of legislative, legal and economic autonomy, there can be no assurance as
to the consequence of the exercise of Chinese sovereignty over Hong Kong on the
future economic and political status of Hong Kong and the Index.

  It is not clear how future developments in Hong Kong and China may affect the
implementation of the Basic Law after the transfer of sovereignty in 1997. As a
result of this political and legal uncertainty, the economic prospects of Hong
Kong and the companies whose stocks comprise the Index are uncertain.
Accordingly, the Hong Kong Stock Exchange has been, and can be expected to
remain, highly volatile and sensitive to adverse political developments with
regard to Hong Kong's future and perceptions of actual or potential political
developments of that kind. For this reason, among others, the Index and the
value of the Notes can also be expected to be volatile.

  Underlying Stocks. The performance of certain companies listed on the Hong
Kong Stock Exchange is linked to the economic climate of China. Any downturn in
economic growth or other negative developments affecting the economic climate of
China could have a material adverse effect on the value of the Index. In
addition, the Hong Kong securities markets are currently characterized by a high
level of investment by and interest among United

                                       6
<PAGE>
 
States and other non-Hong Kong persons. Changes in the level of investment or
interest could have a material adverse effect on the level of the Index.

  Although none of the companies whose stocks comprise the Underlying Stocks are
currently organized under the laws of China, the level of the Index nonetheless
can be affected by developments in China. China currently indirectly influences
political and economic developments in various parts of Asia, including Hong
Kong, and its influence is expected to continue to grow. The government of
China, a socialist state controlled by the Communist Party of China, now permits
private economic activities to a certain extent. Political, economic or social
instability in, and diplomatic and other developments associated with, China
could have a significant effect on economic conditions in Hong Kong and on the
market prices and liquidity of securities traded on the Hong Kong Stock
Exchange, including the Underlying Stocks. Moreover, many of the issuers of the
Underlying Stocks have substantial investments in China, which investments could
be adversely affected by political, economic, market and other developments in
or affecting China. Accordingly, adverse political or economic developments in
China could adversely affect the level of the Index and thus the value of the
Notes.

  Underlying Stocks representing approximately one-third of the market
capitalization of the Index (as of December 29, 1995) are companies engaged in
real estate asset management, development, leasing, property sales and other
related activities. Many factors may have an adverse impact on the credit
quality of these real estate companies and, indirectly, the Index. Generally,
these include economic recession, the cyclical nature of real estate markets,
overbuilding, changing demographics, changes in governmental regulations
(including tax laws and environmental, building, zoning and sales regulations),
increases in real estate taxes or costs of material and labor, the inability to
secure performance guarantees or insurance as required, the unavailability of
investment capital and the inability to obtain construction financing or
mortgage loans at rates acceptable to builders and purchasers of real estate.
Additional risks include an inability to reduce expenditures associated with a
property (such as mortgage payments and property taxes) when rental revenue
declines, and possible loss upon foreclosure of mortgaged properties if mortgage
payments are not paid when due.

OTHER CONSIDERATIONS

  It is suggested that prospective investors who consider purchasing the Notes
should reach an investment decision only after carefully considering the
suitability of the Notes in light of their particular circumstances.

  Investors should also consider the tax consequences of investing in the Notes
and should consult their tax advisors.

  Merrill Lynch & Co., MLPF&S or its affiliates may from time to time engage in
transactions involving the Underlying Stocks for their proprietary accounts and
for other accounts under their management, which may influence the value of such
Underlying Stocks and therefore the value of the Notes. MLPF&S and its
affiliates will also be the counterparties to the hedge of the Company's
obligations under the Notes.  Accordingly, under certain circumstances,
conflicts of interest may arise between MLPF&S's responsibilities as Calculation
Agent with respect to the Notes and its obligations under its hedge and its
status as a subsidiary of the Company.  Under certain circumstances, the duties
of MLPF&S as Calculation Agent in determining the existence of Market Disruption
Events could conflict with the interests of MLPF&S as an affiliate of the issuer
of the Notes, Merrill Lynch & Co., Inc., and with the interests of the holders
of the Notes.


                              DESCRIPTION OF NOTES

GENERAL

  The Notes were issued as a series of Senior Debt Securities under the Senior
Indenture, referred to as the "Senior Indenture", which is more fully described
below. The Notes will mature on February 16, 1999.

                                       7
<PAGE>
 
  While at maturity a beneficial owner of a Note will receive the principal
amount of such Note plus the Supplemental Redemption Amount, if any, there will
be no other payment of interest, periodic or otherwise. (See "Payment at
Maturity" below.)

  The Notes are not subject to redemption by the Company or at the option of any
beneficial owner prior to maturity. Upon the occurrence of an Event of Default
with respect to the Notes, beneficial owners of the Notes may accelerate the
maturity of the Notes, as described under "Description of Notes--Events of
Default and Acceleration" and "Other Terms--Events of Default" in this
Prospectus.

  The Notes were issued in denominations of $1,000 and integral multiples
thereof.

PAYMENT AT MATURITY

  At maturity, a beneficial owner of a Note will be entitled to receive the
principal amount thereof plus a Supplemental Redemption Amount, if any, all as
provided below. If the Ending Index Value of the Index does not exceed the
Benchmark Index Value a beneficial owner of a Note will be entitled to receive
only the principal amount thereof.

  At maturity, a beneficial owner of a Note will be entitled to receive, with
respect to each such Note, (i) the principal amount thereof, and (ii) the
Supplemental Redemption Amount equal in amount to:

     Principal Amount  X  Ending Index Value-Benchmark Index Value
                          ----------------------------------------
                                     Benchmark Index Value

provided, however, that in no event will the Supplemental Redemption Amount be
less than zero or more than $1,000 per $1,000 principal amount of Notes. The
Benchmark Index Value equals 664.83. The Benchmark Index Value was determined on
the Pricing Date by multiplying the Starting Index Value by a factor equal to
115%. The Starting Index Value was determined by the Calculation Agent and
equaled the average (arithmetic mean) of the Computed Index Value as of 10:30
A.M., 11:00 A.M., 11:30 A.M., 12:00 Noon, 12:30 P.M., 2:30 P.M., 3:00 P.M. and
3:30 P.M. (Hong Kong time) on the Pricing Date. The "Computed Index Value" as of
any time means the number obtained by (i) multiplying the last reported sales
prices of each Underlying Stock at such time (as reported by Reuters Information
Services, Inc. with respect to intra-day prices and by The Stock Exchange of
Hong Kong Ltd. (the "Hong Kong Stock Exchange" or "HKSE") with respect to
official closing prices) by the number of shares outstanding (as provided by the
AMEX) to obtain the market capitalization for each of the Underlying Stocks and
(ii) dividing the aggregate market capitalization of all the Underlying Stocks
by the divisor used to calculate the last reported Index (see "The Index"
herein). The AMEX has confirmed that the methodology used by the Calculation
Agent to calculate the Computed Index Value is consistent with that currently
used by the AMEX to calculate the Index. The Ending Index Value will be
determined by MLPF&S (the "Calculation Agent") and will equal the average
(arithmetic mean) of the closing values of the Index determined on each of the
first five Calculation Days during the Calculation Period. If there are fewer
than five Calculation Days, then the Ending Index Value will equal the average
(arithmetic mean) of the closing values of the Index on such Calculation Days,
and if there is only one Calculation Day, then the Ending Index Value will equal
the closing value of the Index on such Calculation Day. If no Calculation Days
occur during the Calculation Period because of Market Disruption Events, then
the Ending Index Value will equal the closing value of the Index determined on
the last scheduled Index Business Day in the Calculation Period, regardless of
the occurrences of a Market Disruption Event on such day. The "Calculation
Period" means the period from and including the seventh scheduled Index Business
Day prior to the maturity date to and including the second scheduled Index
Business Day prior to the maturity date. "Calculation Day" means any Index
Business Day during the Calculation Period on which a Market Disruption Event
has not occurred. For purposes of determining the Ending Index Value, an "Index
Business Day" is a day on which the Hong Kong Stock Exchange is open for trading
and the Index or any Successor Index is calculated and published. All
determinations made by the Calculation Agent shall be at the sole discretion of
the Calculation Agent and, absent

                                       8
<PAGE>
 
a determination by the Calculation Agent of a manifest error, shall be
conclusive for all purposes and binding on the Company and beneficial owners of
the Notes.

  The following table illustrates, for a range of hypothetical Ending Index
Values, (i) the total amount payable at maturity for each $1,000 principal
amount of Notes, (ii) the pretax annualized rate of return to beneficial owners
of Notes, and (iii) the pretax annualized rate of return of an investment in the
stocks underlying the Index (which includes an assumed aggregate dividend yield
of 3.31% per annum, and no change in the U.S. dollar/Hong Kong dollar exchange
rate, as more fully described below).

</TABLE>
- ----------
(1) The annualized rates of return specified in the preceding table are
    calculated on a semiannual bond equivalent basis.
(2) This rate of return assumes (i) an investment of a fixed amount in the
    stocks underlying the Index with the allocation of such amount reflecting
    the relative weights of such stocks in the Index; (ii) a percentage change
    in the aggregate price of such stocks that equals the percentage change in
    the Index from the Starting Index Value to the relevant hypothetical Ending
    Index Value; (iii) a constant dividend yield of 3.31% per annum, paid
    quarterly from the date of initial delivery of Notes, applied to the value
    of the Index at the end of each such quarter assuming such value increases
    or decreases linearly from the Starting Index Value to the applicable
    hypothetical Ending Index Value; (iv) no transaction fees or expenses; (v) a
    term for the Notes from February 7, 1996 to February 16, 1996; (vi) a final
    Index value equal to the Ending Index Value; and (vii) no change in the U.S.
    dollar/Hong Kong dollar exchange rate. The aggregate dividend yield of the
    stocks underlying the Index as of January 16, 1996 was approximately 3.31%.

(3)  The Starting Index Value.

  The above figures are for purposes of illustration only. The actual
Supplemental Redemption Amount received by investors and the pretax annualized
rate of return resulting therefrom will depend entirely on the actual Ending
Index Value determined by the Calculation Agent as provided herein. Historical
data regarding the Index is included in this Prospectus under "The Index--
Historical Data on the Index".

<PAGE>
 
ADJUSTMENTS TO THE INDEX; MARKET DISRUPTION EVENTS

  If at any time the method of calculating the Index, or the value thereof, is
changed in any material respect, or if the Index is in any other way modified so
that such Index does not, in the opinion of the Calculation Agent, fairly
represent the value of the Index had such changes or modifications not been
made, then, from and after such time, the Calculation Agent shall, at the close
of business in New York, New York, on each date that the closing value with
respect to the Ending Index Value is to be calculated, make such adjustments as,
in the good faith judgment of the Calculation Agent, may be necessary in order
to arrive at a calculation of a value of a stock index comparable to the Index
as if such changes or modifications had not been made, and calculate such
closing value with reference to the Index, as adjusted. Accordingly, if the
method of calculating the Index is modified so that the value of such Index is a
fraction or a multiple of what it would have been if it had not been modified
(e.g., due to a split in the Index), then the Calculation Agent shall adjust
such Index in order to arrive at a value of the Index as if it had not been
modified (e.g., as if such split had not occurred).

  "Market Disruption Event" means either of the following events, as determined
by the Calculation Agent:

     (i) a suspension or absence of trading on the HKSE of (a) 20% or more of
  the Underlying Stocks and/or (b) the stocks of any three of the four most
  highly capitalized companies included in the Underlying Stocks which then
  comprise the Index or a Successor Index; or

     (ii) the suspension or material limitation on the HK Futures Exchange or
  any other major futures or securities market (which as of the date of this
  Prospectus includes only the HK Futures Exchange, but which in the Calculation
  Agent's judgment may change in the future) of trading in futures or options
  contracts related to the Hang Seng Index, the Index or a Successor Index.

  The Hang Seng Index uses certain of the same securities in its calculation as
the Index (See "The Index--The Hong Kong Stock Exchange and the Hong Kong
Futures Exchange" herein). For purposes of determining whether a Market
Disruption Event has occurred: (1) a limitation on the hours or number of days
of trading will not constitute a Market Disruption Event if it results from an
announced change in the regular business hours of the relevant exchange, (2) a
decision to permanently discontinue trading in the relevant contract will not
constitute a Market Disruption Event, (3) a suspension of trading in a futures
or options contract on the Index by the AMEX or other major securities market by
reason of (x) a price change exceeding limits set by the AMEX or such securities
market, (y) an imbalance of orders relating to such contracts or (z) a disparity
in bid and ask quotes relating to such contracts will constitute a suspension or
material limitation of trading in futures or options contracts related to the
Index and (4) an "absence of trading" on the HKSE, HK Futures Exchange or a
major securities market on which futures or options contracts related to the
Index are traded will not include any time when the HKSE, HK Futures Exchange or
such securities market, as the case may be, itself is closed for trading under
ordinary circumstances.

DISCONTINUANCE OF THE INDEX

  If the AMEX discontinues publication of the Index and the AMEX or another
entity publishes a successor or substitute index that the Calculation Agent
determines, in its sole discretion, to be comparable to such Index (any such
index being referred to hereinafter as a "Successor Index"), then, upon the
Calculation Agent's notification of such determination to the Trustee and the
Company, the Calculation Agent will substitute the Successor Index as calculated
by the AMEX or such other entity for the Index and calculate the Ending Index
Value as described above under "Payment at Maturity". Upon any selection by the
Calculation Agent of a Successor Index, the Company shall cause notice thereof
to be given to Holders of the Notes.

  If the AMEX discontinues publication of the Index and a Successor Index is not
selected by the Calculation Agent or is no longer published on any of the
Calculation Days, the value to be substituted for the Index for any such
Calculation Day used to calculate the Supplemental Redemption Amount at maturity
will be a value computed

                                       10
<PAGE>
 
by the Calculation Agent for each Calculation Day in accordance with the
procedures last used to calculate the Index prior to any such discontinuance. If
a Successor Index is selected or the Calculation Agent calculates a value as a
substitute for the Index as described below, such Successor Index or value shall
be substituted for the Index for all purposes, including for purposes of
determining whether a Market Disruption Event exists.

  If the AMEX discontinues publication of the Index prior to the period during
which the Supplemental Redemption Amount is to be determined and the Calculation
Agent determines that no Successor Index is available at such time, then on each
Business Day until the earlier to occur of (i) the determination of the Ending
Index Value and (ii) a determination by the Calculation Agent that a Successor
Index is available, the Calculation Agent shall determine the value that would
be used in computing the Supplemental Redemption Amount as described in the
preceding paragraph as if such day were a Calculation Day. The Calculation Agent
will cause notice of each such value to be published not less often than once
each month in The Wall Street Journal (or another newspaper of general
circulation), and arrange for information with respect to such values to be made
available by telephone. Notwithstanding these alternative arrangements,
discontinuance of the publication of the Index may adversely affect trading in
the Notes.

EVENTS OF DEFAULT AND ACCELERATION

  In case an Event of Default with respect to any Notes shall have occurred and
be continuing, the amount payable to a beneficial owner of a Note upon any
acceleration permitted by the Notes, with respect to each $1,000 principal
amount thereof, will be equal to: (i) the initial issue price ($1,000), plus
(ii) an additional amount of contingent interest calculated as though the date
of early repayment were the maturity date of the Notes. See "Description of
Notes-Payment at Maturity" in this Prospectus. If a bankruptcy proceeding is
commenced in respect of the Company, the claim of the beneficial owner of a Note
may be limited, under Section 502(b)(2) of Title 11 of the United States Code,
to the principal amount of the Note plus an additional amount of contingent
interest calculated as though the date of the commencement of the proceeding
were the maturity date of the Notes.

  In case of default in payment at the maturity date of the Notes (whether at
their stated maturity or upon acceleration), from and after the maturity date
the Notes shall bear interest, payable upon demand of the beneficial owners
thereof, at the rate of 5.40% per annum (to the extent that payment of such
interest shall be legally enforceable) on the unpaid amount due and payable on
such date in accordance with the terms of the Notes to the date payment of such
amount has been made or duly provided for.

DEPOSITORY

  The Notes are represented by one or more fully registered global securities
(the "Global Notes"). Each such Global Note has been deposited with, or on
behalf of, The Depository Trust Company ("DTC"), as Depository (the
"Depository"), registered in the name of DTC or a nominee thereof. Unless and
until it is exchanged in whole or in part for Notes in definitive form, no
Global Note may be transferred except as a whole by the Depository to a nominee
of such Depository or by a nominee of such Depository to such Depository or
another nominee of such Depository or by such Depository or any such nominee to
a successor of such Depository or a nominee of such successor.

  DTC has advised the Company as follows: DTC is a limited-purpose trust company
organized under the Banking Law of the State of New York, a member of the
Federal Reserve System, a "clearing corporation" within the meaning of the New
York Uniform Commercial Code, and a "clearing agency" registered pursuant to the
provisions of Section 17A of the Exchange Act. DTC was created to hold
securities of its participants ("Participants") and to facilitate the clearance
and settlement of securities transactions among its Participants in such
securities through electronic book-entry changes in accounts of the
Participants, thereby eliminating the need for physical movement of securities
certificates. DTC's Participants include securities brokers and dealers, banks,
trust companies, clearing corporations, and certain other organizations.

                                       11
<PAGE>
 
  DTC is owned by a number of Participants and by the New York Stock Exchange,
Inc., the American Stock Exchange, Inc. and the National Association of
Securities Dealers, Inc. Access to the DTC book-entry system is also available
to others, such as banks, brokers, dealers and trust companies that clear
through or maintain a custodial relationship with a Participant, either directly
or indirectly ("Indirect Participants").

  Purchases of Notes must be made by or through Participants, which will receive
a credit on the records of DTC. The ownership interest of each actual purchaser
of each Note ("Beneficial Owner") is in turn to be recorded on the Participants'
or Indirect Participants' records. Beneficial Owners will not receive written
confirmation from DTC of their purchase, but Beneficial Owners are expected to
receive written confirmations providing details of the transaction, as well as
periodic statements of their holdings, from the Participant or Indirect
Participant through which the Beneficial Owner entered into the transaction.
Ownership of beneficial interests in such Global Note will be shown on, and the
transfer of such ownership interests will be effected only through, records
maintained by DTC (with respect to interests of Participants) and on the records
of Participants (with respect to interests of persons held through
Participants). The laws of some states may require that certain purchasers of
securities take physical delivery of such securities in definitive form. Such
limits and such laws may impair the ability to own, transfer or pledge
beneficial interests in Global Notes.

  So long as DTC, or its nominee, is the registered owner of a Global Note, DTC
or its nominee, as the case may be, will be considered the sole owner or Holder
of the Notes represented by such Global Note for all purposes under the Senior
Indenture. Except as provided below, Beneficial Owners in a Global Note will not
be entitled to have the Notes represented by such Global Notes registered in
their names, will not receive or be entitled to receive physical delivery of the
Notes in definitive form and will not be considered the owners or Holders
thereof under the Senior Indenture, including for purposes of receiving any
reports delivered by the Company or the Trustee pursuant to the Senior
Indenture. Accordingly, each Person owning a beneficial interest in a Global
Note must rely on the procedures of DTC and, if such Person is not a
Participant, on the procedures of the Participant through which such Person owns
its interest, to exercise any rights of a Holder under the Senior Indenture. The
Company understands that under existing industry practices, in the event that
the Company requests any action of Holders or that an owner of a beneficial
interest in such a Global Note desires to give or take any action which a Holder
is entitled to give or take under the Senior Indenture, DTC would authorize the
Participants holding the relevant beneficial interests to give or take such
action, and such Participants would authorize Beneficial Owners owning through
such Participants to give or take such action or would otherwise act upon the
instructions of Beneficial Owners. Conveyance of notices and other
communications by DTC to Participants, by Participants to Indirect Participants,
and by Participants and Indirect Participants to Beneficial Owners will be
governed by arrangements among them, subject to any statutory or regulatory
requirements as may be in effect from time to time.

  Payment of the principal of, and any Supplemental Redemption Amount with
respect to, Notes registered in the name of DTC or its nominee will be made to
DTC or its nominee, as the case may be, as the Holder of the Global Notes
representing such Notes. None of the Company, the Trustee or any other agent of
the Company or agent of the Trustee will have any responsibility or liability
for any aspect of the records relating to or payments made on account of
beneficial ownership interests or for supervising or reviewing any records
relating to such beneficial ownership interests. The Company expects that DTC,
upon receipt of any payment of principal or any Supplemental Redemption Amount
in respect of a Global Note, will credit the accounts of the Participants with
payment in amounts proportionate to their respective holdings in principal
amount of beneficial interest in such Global Note as shown on the records of
DTC. The Company also expects that payments by Participants to Beneficial Owners
will be governed by standing customer instructions and customary practices, as
is now the case with securities held for the accounts of customers in bearer
form or registered in "street name", and will be the responsibility of such
Participants.

  If (x) any Depository is at any time unwilling or unable to continue as
Depository and a successor depository is not appointed by the Company within 60
days, (y) the Company executes and delivers to the Trustee a Company Order to
the effect that the Global Notes shall be exchangeable or (z) an Event of
Default has occurred and is continuing with respect to the Notes, the Global
Notes will be exchangeable for Notes in definitive form of like

                                       12
<PAGE>
 
tenor and of an equal aggregate principal amount, in denominations of $1,000 and
integral multiples thereof. Such definitive Notes shall be registered in such
name or names as the Depository shall instruct the Trustee. It is expected that
such instructions may be based upon directions received by the Depository from
Participants with respect to ownership of beneficial interests in such Global
Notes.


                                   THE INDEX

THE INDEX

  Unless otherwise stated, all information herein on the Index is derived from
the AMEX or other publicly available sources as of February 2, 1996. Such
information reflects the policies of the AMEX as stated in such sources and such
policies are subject to change by the AMEX.

  The Index is a capitalization-weighted stock index designed, developed,
maintained and operated by, and is a service mark of, the AMEX that measures the
market value performance (share price times the number of shares outstanding) of
selected Hong Kong Stock Exchange listed stocks. The Index currently is based on
the capitalization of 30 Underlying Stocks trading on the Hong Kong Stock
Exchange and is designed to represent a substantial segment of the Hong Kong
stock market. The Hong Kong Stock Exchange is the primary trading market for
most of the 30 Underlying Stocks. The primary trading market for all of the
Underlying Stocks is either Hong Kong or London. Business sector representation
of the Underlying Stocks comprising the Index as of February 2, 1996 was as
follows: property development (33.36%), financing (21.80%), conglomerates
(18.68%), utilities (18.01%) and also includes hotel/leisure (4.33%), airlines
(2.24%), property investment (0.85%), transportation (0.46%) and publishing
(0.24%). The Index was established on June 25, 1993. (See the table below for a
list of the Underlying Stocks as of February 2, 1996.) As of February 2, 1996,
the five largest Underlying Stocks accounted for approximately 48.53% of the
market capitalization of the Index, with the largest being HSBC Holdings plc
(12.30%), followed by Hutchison Whampoa Ltd. (9.80%), Sun Hung Kai Properties
Ltd. (9.45%), Hong Kong Telecommunications Ltd. (9.10%) and Hang Seng Bank Ltd.
(7.88%). The lowest weighted Underlying Stock, as of February 2, 1996, was Tai
Chung (Holdings) Ltd. (0.23%).

  The Index is maintained by the AMEX and will contain at least 30 Underlying
Stocks at all times. In addition, the Underlying Stocks must meet certain
listing and maintenance standards as discussed below. The AMEX may change the
composition of the Index at any time in order to more accurately reflect the
composition and track the movement of the Hong Kong stock market. Any
replacement Underlying Stock must also meet the Underlying Stock listing and
maintenance standards as discussed below. Further, the AMEX may replace
Underlying Stocks in the event of certain corporate events, such as takeovers,
or mergers, that change the nature of the security.

  The AMEX will select Underlying Stocks on the basis of their market weight,
trading liquidity, and representation of the business industries reflected on
the Hong Kong Stock Exchange. The AMEX will require that each Underlying Stock
be one issued by an entity with major business interests in Hong Kong, listed
for trading on the Hong Kong Stock Exchange, and have its primary trading market
located in a country with which the AMEX has an effective surveillance sharing
agreement. The AMEX will remove any Underlying Stock failing to meet the above
listing and maintenance criteria within 30 days after such failure occurs. In
order to ensure that the Index does not contain a large number of thinly-
capitalized, low-priced securities with small public floats and low trading
volumes, the AMEX has also established additional qualification criteria for the
inclusion and maintenance of Underlying Stocks, based on the following
standards: (1) all Underlying Stocks selected for inclusion in the Index must
have and thereafter maintain, an average daily capitalization, as calculated by
the total number of shares outstanding times the latest price per share (in Hong
Kong dollars), measured over the prior 6-month period, of at least
H.K.$3,000,000,000 (approximately U.S.$388,000,000 on the date hereof); (2) all
Underlying Stocks selected for inclusion in the Index must have, and thereafter
maintain, an average daily closing price, measured over the prior 6-month
period, not lower than H.K.$2.50 (approximately U.S.$0.32 on the date hereof);
(3) all Underlying Stocks selected for inclusion in the Index must have, and
thereafter maintain an average daily trading volume,

                                       13
<PAGE>
 
measured over the prior 6-month period, of more than 1,000,000 shares per day,
although up to, but no more than, three Underlying Stocks may have an average
daily trading volume, measured over the prior 6-month period, of less than
1,000,000 shares per day, but in no event less than 500,000 shares per day; and
(4) all Underlying Stocks selected for inclusion in the Index must have, and
thereafter maintain, a minimum "free float" value (total freely tradeable
outstanding shares minus insider holdings), based on a monthly average measured
over the prior 3-month period, of U.S.$238,000,000, although up to, but no more
than, three Underlying Stocks may have a free float value of less than
U.S.$238,000,000 but in no event less than U.S.$150,000,000, measured over the
same period. The AMEX will review and apply the above qualification criteria
relating to the Underlying Stocks on a quarterly basis, conducted the last
business day in January, April, July, and October. Any Underlying Stock failing
to meet the above listing and maintenance criteria will be reviewed on the
second Friday of the second month following the quarterly review to again
determine compliance with the above criteria. Any Underlying Stock failing this
second review will be replaced by a "qualified" Underlying Stock effective upon
the close of business on the following Friday, provided however, that if such
Friday is not a day on which the AMEX is open for trading, the replacement will
be effective at the close of business on the first preceding day on which the
AMEX is open for trading. The AMEX will notify its membership immediately after
it determines to replace an Underlying Stock.

  The annual reports and prospectuses of the companies listed on the Hong Kong
Stock Exchange are available for investors' inspection in the City Hall Library
(a public library in Central Hong Kong). The Hong Kong Stock Exchange library
also has information for each listed company but it is available only to members
of the Hong Kong Stock Exchange.

  A company whose stock is included in the Index is not required to be
incorporated under the laws of Hong Kong.

  The Index is a capitalization-weighted index. A company's market
capitalization is calculated by multiplying the number of shares outstanding by
the company's current share price (in Hong Kong dollars). For valuation purposes
unrelated to the Notes, one Index unit (1.0) is assigned a fixed value of one
U.S. dollar. The Index measures the average change in prices of the Underlying
Stocks, weighted according to their respective market capitalizations, so that
the effect of a percentage price change in an Underlying Stock will be greater
the larger the Underlying Stock's market capitalization. The Index was
established by the AMEX on June 25, 1993, on which date the Index value was set
at 350.00. The daily calculation and public dissemination by the AMEX of the
Index commenced on September 1, 1993. The data relating to the Index was back-
calculated by the AMEX from January 2, 1989 to August 31, 1993. The Index is
calculated by (i) adding the market capitalization of each Underlying Stock and
(ii) dividing such sum by an adjusted base market capitalization or divisor. On
June 25, 1993, the market value of the Underlying Stocks was approximately
H.K.$1,152,829,149,500 (equivalent to approximately U.S.$148,656,241,000 based
on the exchange rate as of such date) and the divisor used to calculate the
Index was 3,293,797,570. The AMEX selected that particular divisor number in
order, among other things, to ensure that the Index was set at a general price
level consistent with other well recognized stock markets. The divisor is
subject to periodic adjustments as set forth below. The Index is calculated once
every Index Calculation Day by the AMEX based on the most recent official
closing prices of each of the Underlying Stocks reported by the Hong Kong Stock
Exchange. Pricing of the Index will be performed each day and be disseminated
before the opening of trading via the Consolidated Tape Authority Network-B
continuously during each day on which the AMEX is open for trading. The
dissemination value, however, will remain the same throughout the trading day
because the trading hours of the Hong Kong Stock Exchange do not overlap with
AMEX trading hours. Accordingly, updated price information for the Underlying
Stocks will be unavailable.

  In order to maintain continuity in the level of the Index in the event of
certain changes due to non-market factors affecting the Underlying Stocks, such
as the addition or deletion of stocks, substitution of stock, stock dividends,
stock splits, distributions of assets to stockholders or other capitalization
events, the divisor used in calculating the Index is adjusted in a manner
designed to prevent any instantaneous change or discontinuity in the level of
the Index and in order that the value of the Index immediately after such change
will equal the level of the Index immediately prior to the change. Thereafter,
the divisor remains at the new value until a further adjustment

                                       14
<PAGE>
 
is necessary as the result of another change. Nevertheless, changes in the
identities and characteristics of the Underlying Stocks may significantly affect
the behavior of the Index over time.

  The AMEX is under no obligation to continue the calculation and dissemination
of the Index and the method by which the Index is calculated and the name "The
AMEX Hong Kong 30 Index" may be changed at the discretion of the AMEX. The Notes
are not sponsored, endorsed, sold or promoted by the AMEX. No inference should
be drawn from the information contained in this Prospectus that the AMEX makes
any representation or warranty, implied or express, to the Company, the
beneficial owners of Notes or any member of the public regarding the
advisability of investing in securities generally or in the Notes in particular
or the ability of the Index to track general stock market performance. The AMEX
has no obligation to take the needs of the Company or the beneficial owners of
Notes into consideration in determining, composing or calculating the Index. The
AMEX is not responsible for, and has not participated in the determination of
the timing of prices for or quantities of, the Notes to be issued or in the
determination or calculation of the equation by which the Supplemental
Redemption Amount is determined. The AMEX has no obligation or liability in
connection with the administration, marketing or trading of the Notes.

  The use of and reference to the Index in connection with the Notes have been
consented to by the AMEX.

  Except with respect to the responsibility of the Calculation Agent to make
certain calculations under certain circumstances as described herein, none of
the Company, the Trustee, the Calculation Agent or the Underwriter accepts any
responsibility for the calculation, maintenance or publication of the Index or
any Successor Index. The AMEX disclaims all responsibility for any inaccuracies
in the data on which the Index is based, or any mistakes or errors or omissions
in the calculations or dissemination of the Index or for the manner in which
such index is applied in determining the Supplemental Redemption Amount, if any.

  A potential investor should review the historical performance of the Index.
The historical performance of the Index should not be taken as an indication of
future performance, and no assurance can be given that the Index will increase
sufficiently to cause the beneficial owners of the Securities to receive an
amount in excess of the principal amount at the maturity of the Securities.

THE HONG KONG STOCK EXCHANGE AND THE HONG KONG FUTURES EXCHANGE

  As of September 29, 1995, the Hong Kong Stock Exchange was the world's ninth
largest stock exchange based on U.S. dollar market capitalization. There are no
market-makers in Hong Kong, but exchange dealers may act as dual capacity
broker-dealers. All of the Underlying Stocks of the Index are traded through the
computerized trading system. Trading is undertaken from 10:00 A.M. to 12:30 P.M.
and then from 2:30 P.M. to 3:55 P.M. (Hong Kong time) every Hong Kong day except
Saturdays, Sundays and other days on which the Hong Kong Stock Exchange is
closed. Hong Kong time is 12 hours ahead of Eastern Daylight Savings Time and 13
hours ahead of Eastern Standard Time. Settlement of trades is required within 48
hours and is conducted by electronic book-entry delivery through the Central
Clearing and Settlement System.

  Due to the time differences between New York City and Hong Kong, on any normal
trading day, trading on the Hong Kong Stock Exchange of the Underlying Stocks
currently will cease at 2:55 A.M. or 3:55 A.M., New York City time. Using the
last reported closing prices of the Underlying Stocks on the Hong Kong Stock
Exchange, the level of the Index on any such trading day generally will be
calculated, published and disseminated by the AMEX in the United States shortly
prior to the opening of trading on the AMEX in New York on the same calendar
day.

  The Hong Kong Stock Exchange has adopted certain measures intended to prevent
any extreme short-term price fluctuations resulting from order imbalances or
market volatility. Where the Hong Kong Stock Exchange considers it necessary for
the protection of the investor or the maintenance of an orderly market, it may
at any time suspend dealings in any securities or cancel the listing of any
securities in such circumstances and subject to such conditions

                                       15
<PAGE>
 
as it thinks fit, whether requested by the listed issuer or not. The Hong Kong
Stock Exchange may also do so where: (1) an issuer fails, in a manner which the
Hong Kong Stock Exchange considers material, to comply with the Hong Kong Stock
Exchange Listing Rules or its Listing Agreements; or (2) the Hong Kong Stock
Exchange considers there are insufficient securities in the hands of the public;
or (3) the Hong Kong Stock Exchange considers that the listed issuer does not
have a sufficient level of operations or sufficient assets to warrant the
continued listing of the issuer's securities; or (4) the Hong Kong Stock
Exchange considers that the issuer or its business is no longer suitable for
listing. Investors should also be aware that the Hong Kong Stock Exchange may
suspend the trading of individual stocks in certain limited and extraordinary
circumstances, until certain price-sensitive information has been disclosed to
the public. For instance, dealing on a listed company's shares will normally be
suspended when information about an intention to make a private placing, or a
very substantial transaction compared to the net asset value of the company, has
been leaked through an improper channel. Trading will not be resumed until after
a formal announcement has been made. Trading of a company's shares may also be
suspended if there is unusual trading activity in that stock.

  An issuer may apply for suspension on its own accord. A suspension request
will normally only be acceded to in the following circumstances: (1) where, for
a reason acceptable to the Hong Kong Stock Exchange, price-sensitive information
cannot at that time be disclosed; (2) where the issuer is subject to an offer,
but only where terms have been agreed in principle and require discussion with,
and agreement by, one or more major shareholders (suspensions will only normally
be appropriate where no previous announcement has been made); (3) to maintain an
orderly market; (4) where there is an occurrence of certain levels of notifiable
transactions, such as substantial changes in the nature, control or structure of
the issuer, where publication of full details is necessary to permit a realistic
valuation to be made of the securities concerned, or the approval of
shareholders is required; (5) where the issuer is no longer suitable for
listing, or becomes a "cash" company; or (6) for issuers going into receivership
or liquidation.

  As a result of the foregoing, variations in the Index may be limited by
suspension of trading of individual stocks which comprise the Index which may in
turn, adversely affect the value of the Notes. In addition, a partial or total
halt in trading of all of the Underlying Stocks could result in a Market
Disruption Event. See "Description of Notes--Adjustments to the Index; Market
Disruption Events" herein.

  Because the Index uses certain of the same securities in its calculation as
the Hang Seng Index ("HSI"), another stock index, the HSI is referenced to
determine if a Market Disruption Event has occurred. A Market Disruption Event
can occur if there is a suspension or material limitation on the HK Futures
Exchange of trading in futures or options contracts related to the HSI. The
stock index contracts traded on the HK Futures Exchange are based upon the HSI
and its four sub-indices: properties, utilities, finance, and commerce and
industry. The HSI is a value-weighted index of 33 stocks and every stock in the
HSI is represented in one of the four sub-indices. The following Underlying
Stocks of the Index (as of December 29, 1995) are not constituent securities of
the HSI: Chinese Estates Holdings, Henderson Investment Ltd. and Tai Cheung
(Holdings) Ltd. The following constituent securities of the HSI (as of December
29, 1995) are not Underlying Stocks of the Index: Hong Kong Aircraft Eng. Co.
Ltd., Johnson Electric Holdings Ltd., Mirmar Hotel and Inv. Co. Ltd., Shangri-La
Asia Ltd., South China Morning Post (Holdings) Ltd. and Television Broadcasts
Ltd. The Index also differs from the HSI in that, among other things, the
selection, maintenance and replacement criteria for the constituent securities
of the two indices are not the same and that they are operated and governed by
the rules of different entities.

  Currently, the contracts listed on the HK Futures Exchange are HSI futures,
HSI sub-indices futures, HSI options, gold and Hong Kong Interbank Offered Rate
futures. There is a daily maximum fluctuation limit of 300 points imposed on the
HSI contracts (not applicable to spot mark contracts). Once the limit is
touched, orders cannot be transacted above (the outside limit) or below (the
downside limit) but orders within the range can continue to trade.

  The foregoing discussion reflects the current rules governing the Hong Kong
Stock Exchange and the HK Futures Exchange, which are subject to change.

                                  OTHER TERMS

GENERAL

  The Securities were issued as a series of Senior Debt Securities under the
Indenture (the "Senior Indenture"), dated as of April 1, 1983, as amended and
restated, between the Company and The Chase Manhattan Bank, formerly known as
Chemical Bank (successor by merger to Manufacturers Hanover Trust Company), as
trustee (the "Trustee"). A copy of the Senior Indenture is filed as an exhibit
to the registration statements relating to the Securities. The following
summaries of certain provisions of the Senior Indenture do not purport to be
complete and are subject to, and qualified in their entirety by reference to,
all provisions of the Senior Indenture, including the definition therein of
certain terms.

  The Senior Indenture provides that series of Senior Debt Securities may from
time to time be issued thereunder, without limitation as to aggregate principal
amount, in one or more series and upon such terms as the Company may establish
pursuant to the provisions thereof.

  The Senior Indenture provides that the Senior Indenture and the Securities are
governed by and construed in accordance with the laws of the State of New York.

  The Senior Indenture provides that the Company may issue Senior Debt
Securities with terms different from those of Senior Debt Securities previously
issued, and "reopen" a previously issued series of Senior Debt Securities and
issue additional Senior Debt Securities of such series.

  The Senior Debt Securities are unsecured and rank pari passu with all other
unsecured and unsubordinated indebtedness of the Company.  However, since the
Company is a holding company, the right of the Company, and hence the right of
creditors of the Company (including the Holders of Senior Debt Securities), to
participate in any distribution of the assets of any subsidiary upon its
liquidation or reorganization or otherwise is necessarily subject to the prior
claims of creditors of the subsidiary, except to the extent that claims of the
Company itself as a creditor of the subsidiary may be recognized.  In addition,
dividends, loans and advances from certain subsidiaries, including MLPF&S, to
the Company are restricted by net capital requirements under the Exchange Act
and under rules of certain exchanges and other regulatory bodies.

LIMITATIONS UPON LIENS

  The Company may not, and may not permit any Subsidiary to, create, assume,
incur or permit to exist any indebtedness for borrowed money secured by a
pledge, lien or other encumbrance (except for certain liens specifically
permitted by the Senior Indenture) on the Voting Stock owned directly or
indirectly by the Company of any Subsidiary (other than a Subsidiary which, at
the time of the incurrence of such secured indebtedness, has a net worth of less
than $3,000,000) without making effective provision whereby the Outstanding
Senior Debt Securities will be secured equally and ratably with such secured
indebtedness.

                                       17
<PAGE>
 
LIMITATION ON DISPOSITION OF VOTING STOCK OF, AND MERGER AND SALE OF ASSETS BY,
MLPF&S

  The Indenture provides that the Company may not sell, transfer or otherwise
dispose of any Voting Stock of MLPF&S or permit MLPF&S to issue, sell or
otherwise dispose of any of its Voting Stock, unless, after giving effect to any
such transaction, MLPF&S remains a Controlled Subsidiary (defined in the Senior
Indenture to mean a corporation more than 80% of the outstanding shares of
Voting Stock of which are owned directly or indirectly by the Company).  In
addition, the Company may not permit MLPF&S to (i) merge or consolidate, unless
the surviving company is a Controlled Subsidiary or (ii) convey or transfer its
properties and assets substantially as an entirety, except to one or more
Controlled Subsidiaries.

MERGER AND CONSOLIDATION

  The Indenture provides that the Company may consolidate or merge with or into
any other corporation, and the Company may sell, lease or convey all or
substantially all of its assets to any corporation, provided that (i) the
corporation (if other than the Company) formed by or resulting from any such
consolidation or merger or which shall have received such assets shall be a
corporation organized and existing under the laws of the United States of
America or a state thereof and shall assume payment of the principal of (and
premium, if any) and interest on the Senior Debt Securities and the performance
and observance of all of the covenants and conditions of the Senior Indenture to
be performed or observed by the Company, and (ii) the Company or such successor
corporation, as the case may be, shall not immediately thereafter be in default
under the Senior Indenture.

MODIFICATION AND WAIVER

  Modification and amendment of the Indenture may be effected by the Company and
the Trustee with the consent of the Holders of 66 2/3% in principal amount of
the Outstanding Senior Debt Securities of each series issued pursuant to such
indenture and affected thereby, provided that no such modification or amendment
may, without the consent of the Holder of each Outstanding Senior Debt Security
affected thereby, (a) change the Stated Maturity of the principal of, or any
installment of interest or Additional Amounts payable on, any Senior Debt
Security or any premium payable on the redemption thereof, or change the
Redemption Price; (b) reduce the principal amount of, or the interest or
Additional Amounts payable on, any Senior Debt Security or reduce the amount of
principal which could be declared due and payable prior to the Stated Maturity;
(c) change place or currency of any payment of principal or any premium,
interest or Additional Amounts payable on any Senior Debt Security; (d) impair
the right to institute suit for the enforcement of any payment on or with
respect to any Senior Debt Security; (e) reduce the percentage in principal
amount of the Outstanding Senior Debt Securities of any series, the consent of
whose Holders is required to modify or amend the Indenture; or (f) modify the
foregoing requirements or reduce the percentage of Outstanding Senior Debt
Securities necessary to waive any past default to less than a majority.  No
modification or amendment of the Subordinated Indenture or any Subsequent
Indenture for Subordinated Debt Securities may adversely affect the rights of
any holder of Senior Indebtedness without the consent of such Holder.  Except
with respect to certain fundamental provisions, the Holders of at least a
majority in principal amount of Outstanding Senior Debt Securities of any series
may, with respect to such series, waive past defaults under the Indenture and
waive compliance by the Company with certain provisions thereof.

EVENTS OF DEFAULT

  Under the Senior Indenture, the following will be Events of Default with
respect to Senior Debt Securities of any series: (a) default in the payment of
any interest or Additional Amounts payable on any Senior Debt Security of that
series when due, continued for 30 days; (b) default in the payment of any
principal or premium, if any, on any Senior Debt Security of that series when
due; (c) default in the deposit of any sinking fund payment, when due, in
respect of any Senior Debt Security of that series; (d) default in the
performance of any other covenant of the Company contained in the Indenture for
the benefit of such series or in the Senior Debt Securities of such series,
continued for 60 days after written notice as provided in the Senior Indenture;
(e) certain events in bankruptcy, insolvency or reorganization; and (f) any
other Event of Default provided with respect to Senior Debt Securities of

                                       18
<PAGE>
 
that series.  The Trustee or the Holders of 25% in principal amount of the
Outstanding Senior Debt Securities of that series may declare the principal
amount (or such lesser amount as may be provided for in the Senior Debt
Securities of that series) of all Outstanding Senior Debt Securities of that
series and the interest due thereon and Additional Amounts payable in respect
thereof, if any to be due and payable immediately if an Event of Default with
respect to Senior Debt Securities of such series shall occur and be continuing
at the time of such declaration.  At any time after a declaration of
acceleration has been made with respect to Senior Debt Securities of any series
but before a judgment or decree for payment of money due has been obtained by
the Trustee, the Holders of a majority in principal amount of the Outstanding
Senior Debt Securities of that series may rescind any declaration of
acceleration and its consequences, if all payments due (other than those due as
a result of acceleration) have been made and all Events of Default have been
remedied or waived.  Any Event of Default with respect to Senior Debt Securities
of any series may be waived by the Holders of a majority in principal amount of
all Outstanding Senior Debt Securities of that series, except in a case of
failure to pay principal or premium, if any, or interest or Additional Amounts
payable on any Senior Debt Security of that series for which payment had not
been subsequently made or in respect of a covenant or provision which cannot be
modified or amended without the consent of the Holder of each Outstanding Senior
Debt Security of such series affected.

  The Holders of a majority in principal amount of the Outstanding Senior Debt
Securities of a series may 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 Senior Debt Securities of such
series, provided that such direction shall not be in conflict with any rule of
law or the Senior Indenture.  Before proceeding to exercise any right or power
under the Senior Indenture at the direction of such Holders, the Trustee shall
be entitled to receive from such Holders reasonable security or indemnity
against the costs, expenses and liabilities which might be incurred by it in
complying with any such direction.

  The Company is required to furnish to the Trustee annually a statement as to
the fulfillment by the Company of all of its obligations under the Senior
Indenture.

                           MERRILL LYNCH & CO., INC.

Equity Participation Securities with Minimum Return Protection due June 30, 1999

   On June 28, 1993, Merrill Lynch & Co., Inc. (the "Company") issued
$355,000,000 aggregate principal amount of Equity Participation Securities with
Minimum Return Protection due June 30, 1999 (the "Securities", or the "Notes").
As of the date of this Prospectus, $220,000,000 aggregate principal amount of
the Securities remain outstanding.  The Securities were issued in denominations
of $1,000 and integral multiples thereof, bear no periodic payments of interest
and will mature on June 30, 1999. At maturity, a beneficial owner of a Security
will be entitled to receive, with respect to each Security, the principal amount
thereof plus an interest payment (the "Supplemental Redemption Amount") based on
the percentage increase, if any, in the S&P 500 Composite Stock Price Index (the
"S&P 500 Index"). The Securities were issued as a series of Senior Debt
Securities under the Senior Indenture described herein. The Securities are not
redeemable prior to maturity.

   The Supplemental Redemption Amount payable with respect to a Security at
maturity will equal the product of (A) the principal amount of the applicable
Security, (B) the percentage change from 447.43, the closing value of the S&P
500 Index on June 16, 1993, as compared to the Final Average Value, and (C)
128%. In no event, however, will the Supplemental Redemption Amount be less than
$200 per $1,000 principal amount of the Securities (the "Minimum Supplemental
Redemption Amount"), representing a minimum annualized rate of return of 3.06%.
The calculation of the Final Average Value, as more fully described herein, will
equal the arithmetic average of the closing values of the S&P 500 Index on
certain days during June of 1997, 1998 and 1999.

   For information as to the calculation of the Supplemental Redemption Amount
which will be paid at maturity and the calculation and the composition of the
S&P 500 Index, see "Description of Securities" and "The Standard & Poor's 500
Index" in this Prospectus. FOR OTHER INFORMATION THAT SHOULD BE CONSIDERED BY
PROSPECTIVE INVESTORS, SEE "RISK FACTORS" BEGINNING ON PAGE 4 OF THIS
PROSPECTUS.

   Ownership of the Securities will be maintained in book-entry form by or
through the Depository. Beneficial owners of the Securities will not have the
right to receive physical certificates evidencing their ownership except under
the limited circumstances described herein.

   The Securities have been listed on the New York Stock Exchange under the
symbol "MERP ZR99".

                                 RISK FACTORS

Payment at Maturity

  Investors should be aware that if the Final Average Value of the S&P 500 Index
does not exceed the Initial Value by more than approximately 15.63%, beneficial
owners of the Securities will receive only the principal amount thereof and the
Minimum Supplemental Redemption Amount. A beneficial owner of the Securities may
receive a Supplemental Redemption Amount equal only to the Minimum Supplemental
Redemption Amount at maturity, and such Minimum Supplemental Redemption Amount
is below what the Company would pay as interest as of the date of issuance if
the Company issued non-callable senior debt securities with a similar maturity
as that of the Securities. The return of principal of the Securities at maturity
and the payment of the Minimum Supplemental Redemption Amount are not expected
to reflect the full opportunity costs implied by inflation or other factors
relating to the time value of money.

  The S&P 500 Index does not reflect the payment of dividends on the stocks
underlying it and therefore, in addition to the considerations regarding
averaging discussed below, the yield based on the S&P 500 Index to the maturity
of the Securities will not produce the same yield as if such underlying stocks
were purchased and held for a similar period.

  Because the Final Average Value will be based upon average values of the S&P
500 Index during specified periods in three successive years, a significant
increase in the S&P 500 Index as measured by the average values during the
specified period in the final year, or in either earlier year, may be
substantially or entirely offset by the average values of the S&P 500 Index
during the specified periods in the other two years.

Trading

  The Securities have been listed on the New York Stock Exchange under the
symbol "MERP ZR99". There can be no assurances as to how the Securities will
trade in the secondary market or whether such market will be liquid.  It is
expected that the secondary market for the Securities will be affected by the
creditworthiness of the Company and by a number of other factors. Because the
Final Average Value is an average of the three Calculation Values as described
below, the price at which a beneficial owner of a Security will be able to sell
such Security in the secondary market may be at a discount if the first or
second such Calculation Value is below the Initial Value.

  The trading value of the Securities is expected to depend primarily on the
extent of the appreciation, if any, of the S&P 500 Index over the Initial Value.
If, however, Securities are sold prior to the maturity date at a time when the
S&P 500 Index exceeds the Initial Value, the sale price may be at a discount
from the amount expected to be payable to the beneficial owner if such excess of
the S&P 500 Index over the Initial Value were to prevail until maturity of the
Securities because of the possible fluctuation of the S&P 500 Index between the
time of such sale and the maturity date and the effect of the value of the S&P
500 Index on prior days used to calculate the Final Average Value, if any.
Furthermore, the price at which a beneficial owner will be able to sell
Securities prior to maturity may be at a discount, which could be substantial,
from the principal amount thereof, if, at such time, the S&P 500 Index is below,
equal to or not sufficiently above the Initial Value and/or if the value of the
S&P 500 Index on prior days used to calculate the Final Average Value, if any,
was below, equal to or not sufficiently above the Initial Value. A discount
could also result from rising interest rates.

  The trading values of the Securities may be affected by a number of
interrelated factors, including the creditworthiness of the Company and those
factors listed below. The relationship among these factors is complex, including
how these factors affect the relative value of the principal amount of the
Securities to be repaid at maturity and the value of the Supplemental Redemption
Amount. Accordingly, investors should be aware that factors other than the level
of the S&P 500 Index are likely to affect the Securities' trading value. The
expected theorized effect on the trading value of the Securities of each of the
factors listed below, assuming in each case that all other factors are held
constant, is as follows:

  Interest Rates. In general, if U.S. interest rates increase, the value of the
  Securities is expected to decrease. If U.S. interest rates decrease, the value
  of the Securities is expected to increase. Interest rates may also affect the
  U.S. economy, and, in turn, the value of the S&P 500 Index. Rising interest
  rates may lower the value of the

                                       4
<PAGE>
 
  S&P 500 Index and, thus, the Securities. Falling interest rates may increase
  the value of the S&P 500 Index and, thus, may increase the value of the
  Securities.

  Volatility of the S&P 500 Index. If the volatility of the S&P 500 Index
  increases, the trading value of the Securities is expected to increase. If the
  volatility of the S&P 500 Index decreases, the trading value of the Securities
  is expected to decrease.

  Time Remaining to Maturity. The Securities may trade at a value above that
  which may be inferred from the level of interest rates and the S&P 500 Index.
  This difference will reflect a "time premium" due to expectations concerning
  the value of the S&P 500 Index during the period prior to maturity of the
  Securities. As the time remaining to maturity of the Securities decreases,
  however, this time premium is expected to decrease, thus decreasing the
  trading value of the Securities. In addition, the price at which a beneficial
  owner may be able to sell Securities prior to maturity may be at a discount,
  which may be substantial, from the minimum expected value at maturity if one
  or more Calculation Values, as defined below, were below, equal to or not
  sufficiently above the Initial Value.

  Dividend Rates in the United States. If dividend rates on the stocks
  comprising the S&P 500 Index increase, the value of the Securities is expected
  to decrease. Conversely, if dividend rates on the stocks comprising the S&P
  500 Index decrease, the value of the Securities is expected to increase.
  However, in general, rising U.S. corporate dividend rates may increase the
  value of the S&P 500 Index and, in turn, increase the value of the Securities.
  Conversely, falling U.S. dividend rates may decrease the value of the S&P 500
  Index and, in turn, decrease the value of the Securities.

Other Considerations

  It is suggested that prospective investors who consider purchasing the
Securities should reach an investment decision only after carefully considering
the suitability of the Securities in light of their particular circumstances.

  Investors should also consider the tax consequences of investing in the
Securities and should consult their tax advisors.


                           DESCRIPTION OF SECURITIES
General

  The Securities were issued as a series of Senior Debt Securities under the
Senior Indenture, dated as of April 1, 1983, as amended and restated, which is
more fully described under "Other Terms" in this Prospectus.  The Securities
will mature on June 30, 1999.

   No periodic payments of interest will be payable with respect to the
Securities. (See "Payment at Maturity", below.)

  The Securities are not subject to redemption by the Company or at the option
of any beneficial owner prior to maturity. Upon the occurrence of an Event of
Default with respect to the Securities, beneficial owners of the Securities may
accelerate the maturity of the Securities, as described under "Description of
Securities--Events of Default and Acceleration" and "Other Terms--Events of
Default" in this Prospectus.

  The Securities are transferable in denominations of $1,000 and integral
multiples thereof.

Payment at Maturity

  At maturity, a beneficial owner of a Security will be entitled to receive the
principal amount thereof plus a Supplemental Redemption Amount, all as provided
below. If the Final Average Value of the S&P 500 Index does not exceed the
Initial Value by more than approximately 15.63%, a beneficial owner of a
Security will be entitled to receive only the principal amount thereof and the
Minimum Supplemental Redemption Amount.

                                       5
<PAGE>
 
  At maturity, a beneficial owner of a Security will be entitled to receive,
with respect to each such Security, (i) the principal amount thereof, and (ii)
the Supplemental Redemption Amount equal in amount to:


      Principal Amount    x     Final Average Value-Initial Value    x    128%
                                ---------------------------------             
                               Initial Value

provided, that the Supplemental Redemption Amount will not be less than the
Minimum Supplemental Redemption Amount of $200 per $1,000 principal amount of
Securities. The Initial Value equals 447.43, the closing value of the S&P 500
Index on June 16, 1993.

  The Final Average Value of the S&P 500 Index will be determined by State
Street Bank and Trust Company (the "Calculation Agent") and will equal the
arithmetic average (mean) of the Yearly Values, as defined below, for 1997, 1998
and 1999. The Yearly Value for any year will be calculated during the
Calculation Period for such year which will be from and including June 18 in
1997, June 18 in 1998 and June 17 in 1999 to and including the fifth scheduled
Business Day after such date. The Yearly Value for each year will equal the
arithmetic average (mean) of the closing values of the S&P 500 Index on the
first day in the applicable Calculation Period (provided that a Market
Disruption Event, as defined below, shall not have occurred on such day) and on
each succeeding Business Day (provided that a Market Disruption Event shall not
have occurred on the applicable day) up to and including the last Business Day
in the applicable Calculation Period (each, a "Calculation Date") until the
Calculation Agent has so determined such closing values for five Business Days.
If a Market Disruption Event occurs on two or more of the Business Days during a
Calculation Period, the Yearly Value for the relevant year will equal the
average of the values on Business Days on which a Market Disruption Event did
not occur during such Calculation Period or, if there is only one such Business
Day, the value on such day. If Market Disruption Events occur on all of such
Business Days during a Calculation Period, the Yearly Value for the relevant
year shall equal the closing value of the S&P 500 Index on the last Business Day
of the Calculation Period regardless of whether a Market Disruption Event shall
have occurred on such day.

  For purposes of determining the Final Average Value, a "Business Day" is a day
on which The New York Stock Exchange is open for trading. All determinations
made by the Calculation Agent shall be at the sole discretion of the Calculation
Agent and, absent a determination by the Calculation Agent of a manifest error,
shall be conclusive for all purposes and binding on the Company and beneficial
owners of the Securities.

  If S&P discontinues publication of the S&P 500 Index and S&P or another entity
publishes a successor or substitute index that the Calculation Agent determines,
in its sole discretion, to be comparable to the S&P 500 Index (any such index
being referred to hereinafter as a "Successor Index"), then, upon the
Calculation Agent's notification of such determination to the Trustee and the
Company, the Calculation Agent will substitute the Successor Index as calculated
by S&P or such other entity for the S&P 500 Index and calculate the Final
Average Value as described in the preceding paragraph. Upon any selection by the
Calculation Agent of a Successor Index, the Company shall cause notice thereof
to be published in The Wall Street Journal (or another newspaper of general
circulation) within three Business Days of such selection.

  If S&P discontinues publication of the S&P 500 Index and a Successor Index is
not selected by the Calculation Agent or is no longer published on any of the
Calculation Dates, the value to be substituted for the S&P 500 Index for any
such Calculation Date used to calculate the Supplemental Redemption Amount at
maturity will be calculated as described below under "Discontinuance of the S&P
500 Index".

  If a Successor Index is selected or the Calculation Agent calculates a value
as a substitute for the S&P 500 Index as described below, such Successor Index
or value shall be substituted for the S&P 500 Index for all purposes, including
for purposes of determining whether a Market Disruption Event exists.

  If at any time the method of calculating the S&P 500 Index, or the value
thereof, is changed in a material respect, or if the S&P 500 Index is in any
other way modified so that such Index does not, in the opinion of the
Calculation Agent, fairly represent the value of the S&P 500 Index had such
changes or modifications not been made, then, from and after such time, the
Calculation Agent shall, at the close of business in New York, New York, on each
date that the closing value with respect to the Final Average Value is to be
calculated, make such adjustments as, in the good faith judgment of the
Calculation Agent, may be necessary in order to arrive at a calculation of a

                                       6
<PAGE>
 
value of a stock index comparable to the S&P 500 Index as if such changes or
modifications had not been made, and calculate such closing value with reference
to the S&P 500 Index, as adjusted. Accordingly, if the method of calculating the
S&P 500 Index is modified so that the value of such Index is a fraction or a
multiple of what it would have been if it had not been modified (e.g., due to a
split in the Index), then the Calculation Agent shall adjust such Index in order
to arrive at a value of the S&P 500 Index as if it had not been modified (e.g.,
as if such split had not occurred).

   "Market Disruption Event" means either of the following events, as determined
by the Calculation Agent:

    (i)  the suspension or material limitation (limitations pursuant to New York
  Stock Exchange Rule 80A (or any applicable rule or regulation enacted or
  promulgated by the New York Stock Exchange, any other self regulatory
  organization or the Commission of similar scope as determined by the
  Calculation Agent) on trading during significant market fluctuations shall be
  considered "material" for purposes of this definition), in each case, for more
  than two hours of trading in 100 or more of the securities included in the S&P
  500 Index, or

      (ii)  the suspension or material limitation, in each case, for more than
   two hours of trading (whether by reason of movements in price otherwise
   exceeding levels permitted by the relevant exchange or otherwise) in (A)
   futures contracts related to the S&P 500 Index which are traded on the
   Chicago Mercantile Exchange or (B) option contracts related to the S&P 500
   Index which are traded on the Chicago Board Options Exchange, Inc.

   For the purposes of this definition, a limitation on the hours in a trading
day and/or number of days of trading will not constitute a Market Disruption
Event if it results from an announced change in the regular business hours of
the relevant exchange.

   The following table illustrates, for a range of hypothetical Final Average
Values, the total amount payable at maturity for each $1,000 principal amount of
Securities.

  The above figures are for purposes of illustration only. The actual Total
Redemption Amount received by investors will depend entirely on the actual Final
Average Value determined by the Calculation Agent as provided herein. Because
the Final Average Value will be based upon average values of the S&P 500 Index
during specified periods in three successive years, a significant increase or
decrease in the S&P 500 Index as measured by the average values during the
specified period in any year may be substantially or entirely offset by the
average values of the S&P 500 Index during the specified periods in the other
two years.

  The Senior Indenture provides that the Senior Indenture and the Securities are
governed by and construed in accordance with the laws of the state of New York.
Under present New York law, the maximum rate of interest is 25% per annum on a
simple interest basis. This limit may not apply to Securities in which
$2,500,000 or more has been invested. While the Company believes that New York
law would be given effect by a state or federal court sitting outside of New
York, state laws frequently regulate the amount of interest that may be charged
to and paid by a borrower (including, in some cases, corporate borrowers). It is
suggested that prospective investors consult their personal advisors with
respect to the applicability of such laws. The Company has covenanted for the
benefit of the beneficial owners of the Securities, to the extent permitted by
law, not to claim voluntarily the benefits of any laws concerning usurious rates
of interest against a beneficial owner of the Securities.

Discontinuance of the S&P 500 Index and Successor Index

  If S&P discontinues publication of the S&P 500 Index and a Successor Index is
available, then the amount payable at maturity or upon earlier acceleration will
be determined by reference to the Successor Index, as provided above.

  If the publication of the S&P 500 Index is discontinued and S&P or another
entity does not publish a Successor Index on any of the Calculation Dates, the
value to be substituted for the S&P 500 Index for any such Calculation Date used
to calculate the Supplemental Redemption Amount at maturity will be the value
computed by the Calculation Agent for each such Calculation Date in accordance
with the following procedures:

  (1)  identifying the component stocks of the S&P 500 Index or any Successor
Index as of the last date on which either of such indices was calculated by S&P
or another entity and published by S&P or such other entity (each such component
stock is a "Last Component Stock");

  (2)  for each Last Component Stock, calculating as of each such Calculation
Date the product of the market price per share and the number of the then
outstanding shares (such product referred to as the "Market Value" of such
stock), by reference to (a) the closing market price per share of such Last
Component Stock as quoted by the New York Stock Exchange or the American Stock
Exchange or any other registered national securities exchange that is the
primary market for such Last Component Stock, or if no such quotation is
available, then the closing market price as quoted by any other registered
national securities exchange or the National Association of Securities Dealers
Automated Quotation National Market System ("NASDAQ"), or if no such price is
quoted, then the market price from the best available source as determined by
the Calculation Agent (collectively, the "Exchanges") and (b) the most recent
publicly available statement of the number of outstanding shares of such Last
Component Stock;

  (3)  aggregating the Market Values obtained in clause (2) for all Last
Component Stocks;

  (4)  ascertaining the Base Value (as defined below under "The Standard &
Poor's 500 Index--Computation of the Index") in effect as of the last day on
which either the S&P 500 Index or any Successor Index was published by S&P or
another entity, adjusted as described below;

  (5)  dividing the aggregate Market Value of all Last Component Stocks by the
Base Value (adjusted as aforesaid);

  (6)  multiplying the resulting quotient (expressed in decimals) by ten.

  If any Last Component Stock is no longer publicly traded on any registered
national securities exchange or in the over-the-counter market, the last
available market price per share for such Last Component Stock as quoted by any
registered national securities exchange or in the over-the-counter market, and
the number of outstanding shares

                                       8
<PAGE>
 
thereof at such time, will be used in computing the last available Market Value
of such Last Component Stock. Such Market Value will be used in all computations
of the S&P 500 Index thereafter.

  If a company that has issued a Last Component Stock and another company that
has issued a Last Component Stock are consolidated to form a new company, the
common stock of such new company will be considered a Last Component Stock and
the common stocks of the constituent companies will no longer be considered Last
Component Stocks. If any company that has issued a Last Component Stock merges
with, or acquires, a company that has not issued a Last Component Stock, the
common stock of the surviving corporation will, upon the effectiveness of such
merger or acquisition, be considered a Last Component Stock. In each such case,
the Base Value will be adjusted so that the Base Value immediately after such
consolidation, merger or acquisition will equal (a) the Base Value immediately
prior to such event, multiplied by (b) the quotient of the aggregate Market
Value of all Last Component Stocks immediately after such event, divided by the
aggregate Market Value for all Last Component Stocks immediately prior to such
event.

  If a company that has issued a Last Component Stock issues a stock dividend,
declares a stock split or issues new shares pursuant to the acquisition of
another company, then, in each case, the Base Value will be adjusted (in
accordance with the formula described below) so that the Base Value immediately
after the time the particular Last Component Stock commences trading ex-
dividend, the effectiveness of the stock split or the time new shares of such
Last Component Stock commence trading equals (a) the Base Value immediately
prior to such event, multiplied by (b) the quotient of the aggregate Market
Value for all Last Component Stocks immediately after such event, divided by the
aggregate Market Value of all Last Component Stocks immediately prior to such
event. The Base Value used by the Calculation Agent to calculate the value
described above will not necessarily be adjusted in all cases in which S&P, in
its discretion, might adjust the Base Value (as described below under "The
Standard & Poor's 500 Index--Computation of the S&P 500 Index").

  If S&P discontinues publication of the S&P 500 Index prior to the period
during which the Supplemental Redemption Amount is to be determined and the
Calculation Agent determines that no Successor Index is available at such time,
then on each Business Day until the earlier to occur of (i) the determination of
the Final Average Value and (ii) a determination by the Calculation Agent that a
Successor Index is available, the Calculation Agent shall determine the value
that would be used in computing the Supplemental Redemption Amount by reference
to the method set forth in clauses (1) through (6) in the fourth preceding
paragraph above as if such day were a Calculation Date. The Calculation Agent
will cause notice of each such value to be published not less often than once
each month in The Wall Street Journal (or another newspaper of general
circulation), and arrange for information with respect to such values to be made
available by telephone. Notwithstanding these alternative arrangements,
discontinuance of the publication of the S&P 500 Index may adversely affect
trading in the Securities.

Events of Default and Acceleration

  In case an Event of Default with respect to any Securities shall have occurred
and be continuing, the amount payable to a beneficial owner of a Security upon
any acceleration permitted by the Securities, with respect to each $1,000
principal amount thereof, will be equal to: (i) the initial issue price
($1,000), plus (ii) an additional amount of contingent interest calculated as
though the date of early repayment were the maturity date of the Securities. The
Calculation Period used to calculate the final Yearly Value of the Notes so
accelerated will begin on the eighth scheduled Business Day next preceding the
scheduled date for such early redemption. If such final Yearly Value is the only
Yearly Value which shall have been calculated with respect to the Notes, such
final Yearly Value will be the Final Average Value. If one or two other Yearly
Values shall have been calculated with respect to the Notes for prior years when
the Notes shall have been outstanding, the average of the final Yearly Value and
such one other Yearly Value or such two other Yearly Values, as the case may be,
will be the Final Average Value. The Minimum Supplemental Redemption Amount with
respect to any such early redemption date will be an amount equal to the
interest which would have accrued on the Securities from and including the date
of original issuance to but excluding the date of early redemption at an
annualized rate of 3.06%, calculated on a semiannual bond equivalent basis. See
"Description of Securities--Payment at Maturity" in this Prospectus. If a
bankruptcy proceeding is commenced in respect of the Company, the claim of the
beneficial owner of a Security may be limited, under Section 502(b)(2) of Title
11 of the United States Code, to the principal amount of the Security plus an
additional amount of contingent interest calculated as though the date of the
commencement of the proceeding were the maturity date of the Securities.

                                       9
<PAGE>
 
  In case of default in payment at the maturity date of the Securities (whether
at their stated maturity or upon acceleration), from and after the maturity date
the Securities shall bear interest, payable upon demand of the beneficial owners
thereof, at the rate of 7% per annum (to the extent that payment of such
interest shall be legally enforceable) on the unpaid amount due and payable on
such date in accordance with the terms of the Securities to the date payment of
such amount has been made or duly provided for.

Depository

  The Securities are represented by three fully registered global securities
(the "Global Securities"). Each such Global Security has been deposited with, or
on behalf of, The Depository Trust Company ("DTC"), as Depository (the
"Depository"), registered in the name of DTC or a nominee thereof. Unless and
until it is exchanged in whole or in part for Securities in definitive form, no
Global Security may be transferred except as a whole by the Depository to a
nominee of such Depository or by a nominee of such Depository to such Depository
or another nominee of such Depository or by such Depository or any such nominee
to a successor of such Depository or a nominee of such successor.

  DTC has advised the Company as follows: DTC is a limited-purpose trust company
organized under the Banking Law of the State of New York, a member of the
Federal Reserve System, a "clearing corporation" within the meaning of the New
York Uniform Commercial Code, and a "clearing agency" registered pursuant to the
provisions of Section 17A of the Exchange Act. DTC was created to hold
securities of its participants ("Participants") and to facilitate the clearance
and settlement of securities transactions among its Participants in such
securities through electronic book-entry changes in accounts of the
Participants, thereby eliminating the need for physical movement of securities
certificates. DTC's Participants include securities brokers and dealers, banks,
trust companies, clearing corporations, and certain other organizations.

  DTC is owned by a number of Participants and by the New York Stock Exchange,
Inc., the American Stock Exchange, Inc. and the National Association of
Securities Dealers, Inc. Access to the DTC book-entry system is also available
to others, such as banks, brokers, dealers and trust companies that clear
through or maintain a custodial relationship with a Participant, either directly
or indirectly ("Indirect Participants").

  Purchases of Securities must be made by or through Participants, which will
receive a credit on the records of DTC. The ownership interest of each actual
purchaser of each Security ("Beneficial Owner") is in turn to be recorded on the
Participants' or Indirect Participants' records. Beneficial Owners will not
receive written confirmation from DTC of their purchase, but Beneficial Owners
are expected to receive written confirmations providing details of the
transaction, as well as periodic statements of their holdings, from the
Participant or Indirect Participant through which the Beneficial Owner entered
into the transaction. Ownership of beneficial interests in such Global Security
will be shown on, and the transfer of such ownership interests will be effected
only through, records maintained by DTC (with respect to interests of
Participants) and on the records of Participants (with respect to interests of
persons held through Participants). The laws of some states may require that
certain purchasers of securities take physical delivery of such securities in
definitive form. Such limits and such laws may impair the ability to own,
transfer or pledge beneficial interests in Global Securities.

  So long as DTC, or its nominee, is the registered owner of a Global Security,
DTC or its nominee, as the case may be, will be considered the sole owner or
Holder of the Securities represented by such Global Security for all purposes
under the Senior Indenture. Except as provided below, Beneficial Owners in a
Global Security will not be entitled to have the Securities represented by such
Global Securities registered in their names, will not receive or be entitled to
receive physical delivery of the Securities in definitive form and will not be
considered the owners or Holders thereof under the Senior Indenture.
Accordingly, each Person owning a beneficial interest in a Global Security must
rely on the procedures of DTC and, if such Person is not a Participant, on the
procedures of the Participant through which such Person owns its interest, to
exercise any rights of a Holder under the Senior Indenture. The Company
understands that under existing industry practices, in the event that the
Company requests any action of Holders or that an owner of a beneficial interest
in such a Global Security desires to give or take any action which a Holder is
entitled to give or take under the Senior Indenture, DTC would authorize the
Participants holding the relevant beneficial interests to give or take such
action, and such Participants would authorize Beneficial Owners owning through
such Participants to give or take such action or would otherwise act upon the
instructions of Beneficial Owners. Conveyance of notices and other
communications by DTC to Participants, by Participants to

                                      10
<PAGE>
 
Indirect Participants, and by Participants and Indirect Participants to
Beneficial Owners will be governed by arrangements among them, subject to any
statutory or regulatory requirements as may be in effect from time to time.

  Payment of the principal of, and any Supplemental Redemption Amount with
respect to, Securities registered in the name of DTC or its nominee will be made
to DTC or its nominee, as the case may be, as the Holder of the Global
Securities representing such Securities. None of the Company, the Trustee or any
other agent of the Company or agent of the Trustee will have any responsibility
or liability for any aspect of the records relating to or payments made on
account of beneficial ownership interests or for supervising or reviewing any
records relating to such beneficial ownership interests. The Company expects
that DTC, upon receipt of any payment of principal or any Supplemental
Redemption Amount in respect of a Global Security, will credit the accounts of
the Participants with payment in amounts proportionate to their respective
holdings in principal amount of beneficial interest in such Global Security as
shown on the records of DTC. The Company also expects that payments by
Participants to Beneficial Owners will be governed by standing customer
instructions and customary practices, as is now the case with securities held
for the accounts of customers in bearer form or registered in "street name", and
will be the responsibility of such Participants.

  If (x) any Depository is at any time unwilling or unable to continue as
Depository and a successor depository is not appointed by the Company within 60
days, (y) the Company executes and delivers to the Trustee a Company Order to
the effect that the Global Securities shall be exchangeable or (z) an Event of
Default has occurred and is continuing with respect to the Securities, the
Global Securities will be exchangeable for Securities in definitive form of like
tenor and of an equal aggregate principal amount, in denominations of $1,000 and
integral multiples thereof. Such definitive Securities shall be registered in
such name or names as the Depository shall instruct the Trustee. It is expected
that such instructions may be based upon directions received by the Depository
from Participants with respect to ownership of beneficial interests in such
Global Securities.


                        THE STANDARD & POOR'S 500 INDEX

  All disclosure contained in this Prospectus regarding the S&P 500 Index,
including, without limitation, its make-up, method of calculation and changes in
its components, was derived from publicly available information prepared by S&P
as of May 28, 1993.  The Company takes no responsibility for the accuracy or
completeness of such information.

General

  The S&P 500 Index is published by S&P and is intended to provide an indication
of the pattern of common stock price movement. The calculation of the value of
the S&P 500 Index (discussed below in further detail) is based on the relative
value of the aggregate Market Value (as defined above) of the common stocks of
500 companies as of a particular time as compared to the aggregate average
Market Value of the common stocks of 500 similar companies during the base
period of the years 1941 through 1943. As of May 28, 1993, the 500 companies
included in the S&P 500 Index represented approximately 75% of the aggregate
Market Value of common stocks traded on The New York Stock Exchange; however,
the 500 companies are not the 500 largest companies listed on The New York Stock
Exchange and not all 500 companies are listed on such exchange. As of May 28,
1993, the aggregate market value of the 500 companies included in the S&P 500
Index represented approximately 70% of the aggregate market value of United
States domestic, public companies. S&P chooses companies for inclusion in the
S&P 500 Index with the aim of achieving a distribution by broad industry
groupings that approximates the distribution of these groupings in the common
stock population of The New York Stock Exchange, which S&P uses as an assumed
model for the composition of the total market. Relevant criteria employed by S&P
include the viability of the particular company, the extent to which that
company represents the industry group to which it is assigned, the extent to
which the market price of that company's common stock is generally responsive to
changes in the affairs of the respective industry and the Market Value and
trading activity of the common stock of that company. As of May 28, 1993, the
500 companies included in the Index were divided into 88 individual groups.
These individual groups comprised the following four main groups of companies
(with the number of companies currently included in each group indicated in
parentheses): Industrials (384), Utilities (46), Transportation (15) and
Financial (55). S&P may from time to time, in its sole discretion, add companies
to, or delete companies from, the S&P 500 Index to achieve the objectives stated
above.

                                      11
<PAGE>
 
Computation of the S&P 500 Index

  S&P computes the S&P 500 Index as of a particular time as follows:

       (1)  the Market Value of each component stock is determined as of such
     time;

       (2)  the Market Value of all component stocks as of such time (as
     determined under clause (1) above) are aggregated;

       (3)  the mean average of the Market Values as of each week in the base
     period of the years 1941 through 1943 of the common stock of each company
     in a group of 500 substantially similar companies is determined;

       (4)  the mean average Market Values of all such common stocks over such
     base period (as determined under clause (3) above) are aggregated (such
     aggregate amount being referred to as the "Base Value");

       (5)  the aggregate Market Value of all component stocks as of such time
     (as determined under clause (2) above) is divided by the Base Value; and

       (6)  the resulting quotient (expressed in decimals) is multiplied by ten.

While S&P employs the above methodology to calculate the S&P 500 Index, no
assurance can be given that S&P will not modify or change such methodology in a
manner that may affect the Supplemental Redemption Amount payable to beneficial
owners of Securities upon maturity or otherwise.

     S&P adjusts the foregoing formula to negate the effect of changes in the
Market Value of a component stock that are determined by S&P to be arbitrary or
not due to true market fluctuations. Such changes may result from such causes as
the issuance of stock dividends, the granting to shareholders of rights to
purchase additional shares of such stock, the purchase thereof by employees
pursuant to employee benefit plans, certain consolidations and acquisitions, the
granting to shareholders of rights to purchase other securities of the company,
the substitution by S&P of particular component stocks in the S&P 500 Index, and
other reasons. In all such cases, S&P first recalculates the aggregate Market
Value of all component stocks (after taking account of the new market price per
share of the particular component stock or the new number of outstanding shares
thereof or both, as the case may be) and then determines the New Base Value in
accordance with the following formula:

           Old Base Value     x     New Market Value     =     New Base Value
                                    ----------------                         
                                    Old Market Value

The result is that the Base Value is adjusted in proportion to any change in the
aggregate Market Value of all component stocks resulting from the causes
referred to above to the extent necessary to negate the effects of such causes
upon the S&P 500 Index.

     A potential investor should review the historical performance of the S&P
500 Index.  The historical performance of the S&P 500 Index should not be taken
as an indication of future performance, and no assurance can be given that the
S&P 500 Index will increase sufficiently to cause the beneficial owners of the
Securities to receive an amount in excess of the principal amount plus the
Minimum Supplemental Redemption Amount at the maturity of the Securities.

License Agreement

     S&P and Merrill Lynch Capital Services, Inc. have entered into a non-
exclusive license agreement providing for the license to Merrill Lynch Capital
Services, Inc., in exchange for a fee, of the right to use indices owned and
published by S&P in connection with certain securities, including the
Securities, and the Company is an authorized sublicensee thereof.

     The license agreement between S&P and Merrill Lynch Capital Services, Inc.
provides that the following language must be stated in this Prospectus:

                                      12
<PAGE>
 
     "The Securities are not sponsored, endorsed, sold or promoted by S&P. S&P
     makes no representation or warranty, express or implied, to the Holders of
     the Securities or any member of the public regarding the advisability of
     investing in securities generally or in the Securities particularly or the
     ability of the S&P 500 Index to track general stock market performance.
     S&P's only relationship to Merrill Lynch Capital Services, Inc. and the
     Company (other than transactions entered into in the ordinary course of
     business) is the licensing of certain servicemarks and trade names of S&P
     and of the S&P 500 Index which is determined, composed and calculated by
     S&P without regard to the Company or the Securities. S&P has no obligation
     to take the needs of the Company or the Holders of the Securities into
     consideration in determining, composing or calculating the S&P 500 Index.
     S&P is not responsible for and has not participated in the determination of
     the timing of the sale of the Securities, prices at which the Securities
     are to initially be sold, or quantities of the Securities to be issued or
     in the determination or calculation of the equation by which the Securities
     are to be converted into cash. S&P has no obligation or liability in
     connection with the administration, marketing or trading of the
     Securities."


                                  OTHER TERMS

General

     The Securities were issued as a series of Senior Debt Securities under the
Indenture (the "Senior Indenture"), dated as of April 1, 1983, as amended and
restated, between the Company and The Chase Manhattan Bank, formerly known as
Chemical Bank (successor by merger to Manufacturers Hanover Trust Company), as
trustee (the "Trustee"). A copy of the Senior Indenture is filed as an exhibit
to the registration statements relating to the Securities. The following
summaries of certain provisions of the Senior Indenture do not purport to be
complete and are subject to, and qualified in their entirety by reference to,
all provisions of the Senior Indenture, including the definition therein of
certain terms.

     The Senior Indenture provides that series of Senior Debt Securities may
from time to time be issued thereunder, without limitation as to aggregate
principal amount, in one or more series and upon such terms as the Company may
establish pursuant to the provisions thereof.

     The Senior Indenture provides that the Senior Indenture and the Securities
are governed by and construed in accordance with the laws of the State of New
York.

     The Senior Indenture provides that the Company may issue Senior Debt
Securities with terms different from those of Senior Debt Securities previously
issued, and "reopen" a previously issued series of Senior Debt Securities and
issue additional Senior Debt Securities of such series.

     The Senior Debt Securities are unsecured and rank pari passu with all other
unsecured and unsubordinated indebtedness of the Company.  However, since the
Company is a holding company, the right of the Company, and hence the right of
creditors of the Company (including the Holders of Senior Debt Securities), to
participate in any distribution of the assets of any subsidiary upon its
liquidation or reorganization or otherwise is necessarily subject to the prior
claims of creditors of the subsidiary, except to the extent that claims of the
Company itself as a creditor of the subsidiary may be recognized.  In addition,
dividends, loans and advances from certain subsidiaries, including MLPF&S, to
the Company are restricted by net capital requirements under the Exchange Act,
and under rules of certain exchanges and other regulatory bodies.

Limitations Upon Liens

     The Company may not, and may not permit any Subsidiary to, create, assume,
incur or permit to exist any indebtedness for borrowed money secured by a
pledge, lien or other encumbrance (except for certain liens specifically
permitted by the Senior Indenture) on the Voting Stock owned directly or
indirectly by the Company of any Subsidiary (other than a Subsidiary which, at
the time of the incurrence of such secured indebtedness, has a net worth of less
than $3,000,000) without making effective provision whereby the Outstanding
Senior Debt Securities will be secured equally and ratably with such secured
indebtedness.

                                      13
<PAGE>
 
Limitation on Disposition of Voting Stock of, and Merger and Sale of Assets by,
MLPF&S

     The Indenture provides that the Company may not sell, transfer or otherwise
dispose of any Voting Stock of MLPF&S or permit MLPF&S to issue, sell or
otherwise dispose of any of its Voting Stock, unless, after giving effect to any
such transaction, MLPF&S remains a Controlled Subsidiary (defined in the Senior
Indenture to mean a corporation more than 80% of the outstanding shares of
Voting Stock of which are owned directly or indirectly by the Company).  In
addition, the Company may not permit MLPF&S to (i) merge or consolidate, unless
the surviving company is a Controlled Subsidiary or (ii) convey or transfer its
properties and assets substantially as an entirety, except to one or more
Controlled Subsidiaries.

Merger and Consolidation

     The Indenture provides that the Company may consolidate or merge with or
into any other corporation, and the Company may sell, lease or convey all or
substantially all of its assets to any corporation, provided that (i) the
corporation (if other than the Company) formed by or resulting from any such
consolidation or merger or which shall have received such assets shall be a
corporation organized and existing under the laws of the United States of
America or a state thereof and shall assume payment of the principal of (and
premium, if any) and interest on the Senior Debt Securities and the performance
and observance of all of the covenants and conditions of the Senior Indenture to
be performed or observed by the Company, and (ii) the Company or such successor
corporation, as the case may be, shall not immediately thereafter be in default
under the Senior Indenture.

Modification and Waiver

     Modification and amendment of the Indenture may be effected by the Company
and the Trustee with the consent of the Holders of 66 2/3% in principal amount
of the Outstanding Senior Debt Securities of each series issued pursuant to such
indenture and affected thereby, provided that no such modification or amendment
may, without the consent of the Holder of each Outstanding Senior Debt Security
affected thereby, (a) change the Stated Maturity of the principal of, or any
installment of interest or Additional Amounts payable on, any Senior Debt
Security or any premium payable on the redemption thereof, or change the
Redemption Price; (b) reduce the principal amount of, or the interest or
Additional Amounts payable on, any Senior Debt Security or reduce the amount of
principal which could be declared due and payable prior to the Stated Maturity;
(c) change place or currency of any payment of principal or any premium,
interest or Additional Amounts payable on any Senior Debt Security; (d) impair
the right to institute suit for the enforcement of any payment on or with
respect to any Senior Debt Security; (e) reduce the percentage in principal
amount of the Outstanding Senior Debt Securities of any series, the consent of
whose Holders is required to modify or amend the Indenture; or (f) modify the
foregoing requirements or reduce the percentage of Outstanding Senior Debt
Securities necessary to waive any past default to less than a majority.  No
modification or amendment of the Subordinated Indenture or any Subsequent
Indenture for Subordinated Debt Securities may adversely affect the rights of
any holder of Senior Indebtedness without the consent of such Holder.  Except
with respect to certain fundamental provisions, the Holders of at least a
majority in principal amount of Outstanding Senior Debt Securities of any series
may, with respect to such series, waive past defaults under the Indenture and
waive compliance by the Company with certain provisions thereof.

Events of Default

     Under the Senior Indenture, the following will be Events of Default with
respect to Senior Debt Securities of any series: (a) default in the payment of
any interest or Additional Amounts payable on any Senior Debt Security of that
series when due, continued for 30 days; (b) default in the payment of any
principal or premium, if any, on any Senior Debt Security of that series when
due; (c) default in the deposit of any sinking fund payment, when due, in
respect of any Senior Debt Security of that series; (d) default in the
performance of any other covenant of the Company contained in the Indenture for
the benefit of such series or in the Senior Debt Securities of such series,
continued for 60 days after written notice as provided in the Senior Indenture;
(e) certain events in bankruptcy, insolvency or reorganization; and (f) any
other Event of Default provided with respect to Senior Debt Securities of that
series.  The Trustee or the Holders of 25% in principal amount of the
Outstanding Senior Debt Securities of that series may declare the principal
amount (or such lesser amount as may be provided for in the Senior Debt
Securities of that series) of all Outstanding Senior Debt Securities of that
series and the interest due thereon and Additional Amounts payable in respect
thereof, if any to be due and payable immediately if an Event of Default with
respect to Senior Debt Securities of such series shall occur and be continuing
at the time of such declaration.  At any time

                                      14
<PAGE>
 
after a declaration of acceleration has been made with respect to Senior Debt
Securities of any series but before a judgment or decree for payment of money
due has been obtained by the Trustee, the Holders of a majority in principal
amount of the Outstanding Senior Debt Securities of that series may rescind any
declaration of acceleration and its consequences, if all payments due (other
than those due as a result of acceleration) have been made and all Events of
Default have been remedied or waived.  Any Event of Default with respect to
Senior Debt Securities of any series may be waived by the Holders of a majority
in principal amount of all Outstanding Senior Debt Securities of that series,
except in a case of failure to pay principal or premium, if any, or interest or
Additional Amounts payable on any Senior Debt Security of that series for which
payment had not been subsequently made or in respect of a covenant or provision
which cannot be modified or amended without the consent of the Holder of each
Outstanding Senior Debt Security of such series affected.

     The Holders of a majority in principal amount of the Outstanding Senior
Debt Securities of a series may 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 Senior Debt Securities of such
series, provided that such direction shall not be in conflict with any rule of
law or the Senior Indenture.  Before proceeding to exercise any right or power
under the Senior Indenture at the direction of such Holders, the Trustee shall
be entitled to receive from such Holders reasonable security or indemnity
against the costs, expenses and liabilities which might be incurred by it in
complying with any such direction.

     The Company is required to furnish to the Trustee annually a statement as
to the fulfillment by the Company of all of its obligations under the Senior
Indenture.

                           MERRILL LYNCH & CO., INC.
 EUROPEAN PORTFOLIO MARKET INDEX TARGET-TERM SECURITIES(SM) DUE JUNE 30, 1999
                                  ("MITTS(R)")

     On December 30, 1993, Merrill Lynch & Co., Inc. (the "Company") issued an
aggregate principal amount of $31,000,000 of European Portfolio Market Index
Target-Term Securities due June 30, 1999 (the "Securities" or "MITTS").  Each
$10 principal amount of Securities will be deemed a "Unit" for purposes of
trading and transfer at the Securities Depository described below.  Units will
be transferable by the Securities Depository, as more fully described below, in
denominations of whole Units.

     The Securities will mature on June 30, 1999.  At maturity, a beneficial
owner of a Security will be paid an amount based upon the change in the value of
a portfolio (the "Portfolio") of specified stocks of European companies measured
on December 22, 1993 (the "Original Portfolio Value") through the Calculation
Period, all as more fully described herein; provided, however, that the amount
payable at maturity will not be less than $9.00 for each Unit of the Securities
(the "Minimum Payment").  The Closing Portfolio Value will be based on certain
values of the specified stocks during a period prior to the maturity date of the
Securities.  While at maturity a beneficial owner of a Security may receive an
amount in excess of the principal amount of such Security if the Closing
Portfolio Value exceeds the Original Portfolio Value, there will be no payment
of interest, periodic or otherwise, prior to maturity.

     IF THE CLOSING PORTFOLIO VALUE IS LESS THAN THE ORIGINAL PORTFOLIO VALUE,
THE AMOUNT PAYABLE AT MATURITY WITH RESPECT TO A SECURITY WILL BE LESS THAN THE
PRINCIPAL AMOUNT OF SUCH SECURITY.

     The Securities were issued as a series of Senior Debt Securities under the
Senior Indenture described herein.  The Securities are not redeemable prior to
maturity.

     For information as to the calculation of the amount that will be paid at
maturity and the calculation and the composition of the European portfolio, see
"Description of Securities" and "The Portfolio" in this Prospectus.  FOR OTHER
INFORMATION THAT SHOULD BE CONSIDERED BY PROSPECTIVE INVESTORS, SEE "RISK
FACTORS" BEGINNING ON PAGE 3 OF THIS PROSPECTUS.

     Ownership of the Securities will be maintained in book-entry form by or
through the Securities Depository.  Beneficial owners of the Securities will not
have the right to receive physical certificates evidencing their ownership
except under the limited circumstances described herein.

     The Securities have been listed on the New York Stock Exchange under the
symbol "MEE".

  For the purpose of calculating the ratio of earnings to fixed charges,
"earnings" consists of earnings from continuing operations before income taxes
and fixed charges.  "Fixed charges" consists of interest costs, amortization of
debt expense, preferred stock dividend requirements of majority-owned
subsidiaries, and that portion of rentals estimated to be representative of the
interest factor.


                                  RISK FACTORS

PAYMENT AT MATURITY

  If the Closing Portfolio Value is less than the Original Portfolio Value,
beneficial owners of the Securities will receive less than the principal amount
of such Securities at maturity, but not less than the Minimum Payment.
Beneficial owners would receive only the return of principal if the Closing
Portfolio Value should equal the Original Portfolio Value.  This will be true
even though the Portfolio Value as of some interim period or periods prior to
the Calculation Period may have exceeded the Original Portfolio Value, since the
Closing Portfolio Value is calculated on the basis of the average of the value
of Portfolio Securities only on the Calculation Days.

                                       3
<PAGE>
 
  Even if the principal of the Securities is fully returned, such return of
principal does not reflect any opportunity cost implied by inflation and other
factors relating to the time value of money.

  The return based on the Closing Portfolio Value relative to the Original
Portfolio Value generally will not produce the same return as if the Portfolio
Securities were purchased and held for a similar period, because, among other
reasons, any payment at maturity on the Securities based on an increase in the
value of the Portfolio will not reflect the payment of dividends on the
Portfolio Securities.

  The Senior Indenture provides that the Senior Indenture and the Securities
will be governed by and construed in accordance with the laws of New York.
Under present New York law the maximum rate of interest is 25% per annum on a
simple interest basis.  This limit may not apply to Securities in which
$2,500,000 or more has been invested.  While the Company believes that New York
law would be given effect by a state or federal court sitting outside New York,
state laws frequently regulate the amount of interest that may be charged to and
paid by a borrower (including, in some cases, corporate borrowers).  The Company
has covenanted for the benefit of the Holders of the Securities, to the extent
permitted by law, not to claim voluntarily the benefits of any laws concerning
usurious rates of interest against a Holder of the Securities.

TRADING

  The Securities have been listed on the New York Stock Exchange.  It is
expected that the secondary market for the Securities will be affected by the
creditworthiness of the Company and by a number of other factors.  The trading
value of the Securities is expected to depend primarily on the extent of the
appreciation, if any, of the Portfolio Value over the Original Portfolio Value.
If, however, Securities are sold prior to the maturity date at a time when the
Portfolio Value exceeds the Original Portfolio Value, the sale price may be at a
discount from the amount expected to be payable to the beneficial owner if such
excess of the Portfolio Value over the Original Portfolio Value were to prevail
during the Calculation Period.  Furthermore, the price at which a beneficial
owner will be able to sell Securities prior to maturity may be at a discount,
which could be substantial, from the principal amount thereof, if, at such time,
the Portfolio Value is below, equal to or not sufficiently above the Original
Portfolio Value.  A discount could also result from rising interest rates.

  The trading values of the Securities may be affected by a number of
interrelated factors, including those listed below.  The relationship among
these factors is complex, including how these factors affect the value of the
principal amount of the Securities payable at maturity, if any, in excess of the
principal amount of the Securities.  Accordingly, investors should be aware that
factors other than the level of the Portfolio Value are likely to affect their
trading value.  The expected theoretical effect on the trading value of the
Securities of each of the factors listed below, assuming in each case that all
other factors are held constant, is as follows:

  Interest Rates.  In general, if U.S. interest rates increase, the value of the
  Securities is expected to decrease.  If U.S. interest rates decrease, the
  value of the Securities is expected to increase.  Local interest rates may
  also affect the economies of countries in which issuers of the Portfolio
  Securities or the shares underlying the Portfolio Securities operate, and, in
  turn, affect the Portfolio Value.

  Volatility of the Portfolio Value.  If the volatility of the Portfolio Value
  increases, the trading value of the Securities is expected to increase.  If
  the volatility of the Portfolio Value decreases, the trading value of the
  Securities is expected to decrease.

  Time Remaining to Maturity.  The Securities may trade at a value above that
  which may be inferred from the level of the Portfolio Value.  This difference
  will reflect a "time premium" due to expectations concerning the Portfolio
  Value during the period prior to maturity of the Securities.  As the time
  remaining to maturity of the Securities decreases, however, this time premium
  is expected to decrease, thus decreasing the trading value of the Securities.

                                       4
<PAGE>
 
  Dividend Rates.  If dividend rates on the Portfolio Securities and Underlying
  Shares (as defined herein) increase, the value of the Securities is expected
  to decrease.  Conversely, if dividend rates on the Portfolio Securities and
  Underlying Shares decrease, the value of the Securities is expected to
  increase.  Local general corporate dividend rates may also affect the
  Portfolio Value and, in turn, the value of the Securities.

FOREIGN CURRENCY EXCHANGE RATE AND FOREIGN MARKET CONSIDERATIONS

  The Securities are U.S. dollar-denominated securities issued by the Company, a
United States corporation.  Investments in the Securities do not give the
beneficial owners any right to receive any Portfolio Security or any other
ownership right or interest in the Portfolio Securities, although the return on
the investment in the Securities is based on the Portfolio Value of the
Portfolio Securities.  All of the Portfolio Securities (or securities underlying
the ADRs included in the Portfolio) have been issued by non-United States
companies.  The prices of the securities underlying the ADRs are quoted in
currencies other than the U.S. dollar.  The U.S. dollar price of an ADR will
depend on the price of the security underlying the ADR and the exchange rate
between such foreign currency and the U.S. dollar.  Even if the price in a
foreign currency of the security underlying an ADR is unchanged, changes in the
rates of exchange between the U.S. dollar and such foreign currency will change
the U.S. dollar price of such ADR.  Furthermore, even if the price of the
security underlying the ADR in such foreign currency increases, the U.S. dollar
price of such ADR may decrease as a result of changes in the rates of exchange
between the U.S. dollar and such foreign currency.  The U.S. dollar price of a
Portfolio Security that trades in the United States and outside the United
States and is not an ADR will also be similarly affected by changes in the
exchange rate between the U.S. dollar and the foreign currency in which such
Portfolio Security trades outside the United States.  Rates of exchange between
the dollar and other currencies are determined by forces of supply and demand in
the foreign exchange markets.  These forces are, in turn, affected by
international balance of payments and other economic and financial conditions,
government intervention, speculation and other factors.

  Investments in securities indexed to the value of non-United States securities
involve certain risks.  Fluctuations in foreign exchange rates, future foreign
political and economic developments, and the possible imposition of exchange
controls or other foreign governmental laws or restrictions applicable to such
investments may affect the U.S. dollar value of such securities, including the
Portfolio Securities.  Securities prices in different countries are subject to
different economic, financial, political and social factors.  Individual foreign
economies may differ favorably or unfavorably from the U.S. economy in such
respects as growth of gross national product, rate of inflation, capital
reinvestment, resources, self-sufficiency and balance of payments position.
With respect to certain countries, there is the possibility of expropriation of
assets, confiscatory taxation, political or social instability or diplomatic
developments which could affect the value of investments in those countries.
There may be less publicly available information about a foreign company than
about a U.S. company, and foreign companies may not be subject to accounting,
auditing and financial reporting standards and requirements comparable to those
to which U.S. entities are subject.  Certain foreign investments may be subject
to foreign withholding taxes which could affect the value of investment in these
countries.  In addition, investment laws in certain foreign countries may limit
or restrict ownership of certain securities by foreign nationals by restricting
or eliminating voting or other rights or limiting the amount of securities that
may be so owned, and such limitations or restrictions may affect the prices of
such securities.

  Foreign financial markets, while currently growing in volume, may have
substantially less volume than U.S. markets, and securities of many foreign
companies are less liquid and their prices more volatile than securities of
comparable domestic companies.  The foreign markets have different trading
practices that may affect the prices of securities.  Certain of the foreign
markets on which shares underlying ADRs which are Portfolio Securities trade
impose trading restrictions if certain price movements occur.  The foreign
markets have different clearance and settlement procedures, and in certain
countries there have been times when settlements have been unable to keep pace
with the volume of securities transactions, making it difficult to conduct such
transactions.  There is generally less government supervision and regulation of
exchanges, brokers and issuers in foreign countries than there is in the U.S.
In addition, the terms and conditions of depositary facilities may result in
less liquidity or lower market values for the Portfolio Securities than for the
underlying stocks.

                                       5
<PAGE>
 
AMERICAN DEPOSITARY RECEIPTS

  Certain of the Portfolio Securities are in the form of American Depositary
Receipts ("ADRs").  An ADR is a negotiable receipt which is issued by a
depositary, generally a bank, representing shares (the "Underlying Shares") of a
foreign issuer (the "Foreign Issuer") that have been deposited and are held, on
behalf of the holders of the ADRs, at a custodian bank in the Foreign Issuer's
home country.  While the market for Underlying Shares will generally be in the
country in which the Foreign Issuer is organized, and trading in such market
will generally be based on that country's currency, ADRs that are Portfolio
Securities will trade in U.S. Dollars.

  Although ADRs are distinct securities from the Underlying Shares, the trading
characteristics and valuations of ADRs will usually, but not necessarily, mirror
the characteristics and valuations of the Underlying Shares represented by the
ADRs.  Active trading volume and efficient pricing in the principal market in
the home country for the Underlying Shares will usually indicate similar
characteristics in respect of the ADRs.  In the case of certain ADRs, however,
there may be inadequate familiarity with or information about the Foreign Issuer
of the Underlying Shares represented by the ADR in the market in which the ADR
trades to support active volume, thus resulting in pricing distortions.  This is
more likely to occur when the ADR is not listed on a U.S. stock exchange or
quoted on the National Market System of the National Association of Securities
Dealers Automated Quotations System ("NASDAQ"), and trades only in the over-the-
counter market, because the Foreign Issuer is not required to register such ADRs
under the Exchange Act, as is the case with ADRs so listed or quoted.  In
addition, because of the size of an offering of Underlying Shares in ADR form
outside the home country and/or other factors that have limited or increased the
float of certain ADRs, the liquidity of such securities may be less than or
greater than that with respect to the Underlying Shares.  Inasmuch as holders of
ADRs may surrender the ADR in order to take delivery of and trade the Underlying
Shares, a characteristic that allows investors in ADRs to take advantage of
price differentials between different markets, a market for the Underlying
Shares that is not liquid will generally result in an illiquid market for the
ADR representing such Underlying Shares.

  The depositary bank that issues an ADR generally charges a fee, based on the
price of the ADR, upon issuance and cancellation of the ADR.  This fee would be
in addition to the brokerage commissions paid upon the acquisition or surrender
of the security.  In addition, the depositary bank incurs expenses in connection
with the conversion of dividends or other cash distributions paid in local
currency into U.S. Dollars and such expenses are deducted from the amount of the
dividend or distribution paid to holders, resulting in a lower payout per
Underlying Share represented by the ADR than would be the case if the Underlying
Share were held directly.  Furthermore, foreign investment laws in certain
countries may restrict ownership by foreign nationals of certain classes of
Underlying Shares.  Accordingly, the ADR representing such class of securities
may not possess voting rights, if any, equivalent to those in respect of the
Underlying Shares.  Certain tax considerations, including tax rate
differentials, arising from application of the tax laws of one nation to the
nationals of another and from certain practices in the ADR market may also exist
with respect to certain ADRs.  In varying degrees, any or all of these factors
may affect the value of the ADR compared with the value of the Underlying Shares
in the home market of the issuer.

OTHER CONSIDERATIONS

  It is suggested that prospective investors who consider purchasing the
Securities should reach an investment decision only after carefully considering
the suitability of the Securities in the light of each investor's particular
circumstances.

  Investors should also consider the tax consequences of investing in the
Securities and should consult their tax advisors.

                           DESCRIPTION OF SECURITIES

GENERAL

  The Securities were issued as a series of Senior Debt Securities under the
Senior Indenture, dated as of April 1, 1983, as amended and restated.  The
principal amount of each Security will equal $10 for each Unit.  The Securities
will mature on June 30, 1999.

  While at maturity a beneficial owner of a Security may receive an amount in
excess of the principal amount of such Security if the Closing Portfolio Value
exceeds the Original Portfolio Value, there will be no payment of interest,
periodic or otherwise, prior to maturity.  (See "Payment at Maturity", below.)

  The Securities are not subject to redemption by the Company or at the option
of any Holder prior to maturity.  Upon the occurrence of an Event of Default
with respect to the Securities, Holders of the Securities may accelerate the
maturity of the Securities, as described below.

  The Securities are to be issued in denominations of whole Units.  Each Unit is
equal to $10 principal amount of the Securities.

PAYMENT AT MATURITY

  At maturity, a beneficial owner of a Security will be entitled to receive,
with respect to each $10 principal amount of the Security, an amount equal to
the following:

                        $10  X   Closing Portfolio Value
                                 -----------------------
                                          $100

provided, however, that the amount payable at maturity will not be less than $9
for each $10 principal amount of Securities (the "Minimum Payment").  Based on
the prices of the Portfolio Securities on December 22, 1993, the Multipliers
were initially set so that the value of the Portfolio on such date equalled $100
(the "Original Portfolio Value").

  If the Closing Portfolio Value is equal to $90 or less, a beneficial owner of
a Security will receive the Minimum Payment of $9 for each $10 principal amount
of the Securities at maturity.  If the Closing Portfolio Value is between $90
and $100, a beneficial owner of a Security will receive between $9 and $10 for
each $10 principal amount of the Securities at maturity.

  The "Closing Portfolio Value" will be determined by MLPF&S, an affiliate of
the Company, or successor thereto (the "Calculation Agent"), and will equal the
sum of the products of the Average Market Price and the applicable Multiplier
for each Portfolio Security.  The "Average Market Price" of a Portfolio Security
will equal the average (mean) of the Market Prices of such Portfolio Security
determined on each of the first forty-five Calculation Days with respect to such
Portfolio Security during the Calculation Period.  If there are fewer than
forty-five Calculation Days with respect to a Portfolio Security, then the
Average Market Price with respect to such Portfolio Security will equal the
average (mean) of the Market Prices on such Calculation Days, and if there is
only one Calculation Day, then the Average Market Price will equal the Market
Price on such Calculation Day.  The "Calculation Period" means the period from
and including the ninetieth scheduled NYSE Trading Day (as defined below) prior
to the maturity date to and including the fourth scheduled NYSE Trading Day
prior to the maturity date.  "Calculation Day" with respect to a Portfolio
Security means any Trading Day during the Calculation Period in the country in
which such Portfolio Security is being priced on which a Market Disruption Event
has not occurred.  If a Market Disruption Event occurs on all Trading Days in
such country during the Calculation Period then the fourth scheduled NYSE
Trading Day prior to the maturity date in such country will be deemed a
Calculation Day, notwithstanding the Market Disruption Event; provided, however,
that if such fourth scheduled NYSE Trading Day is not a Trading Day in such
country, then the immediately preceding Trading Day shall instead

                                       7
<PAGE>
 
be deemed a Calculation Day.  Any reference to a specific day herein shall mean
such calendar day in each market in which Portfolio Securities are priced.

  "Market Price" means for a Calculation Day the following:

  (a) If the Portfolio Security is listed on a national securities exchange in
  the United States, is a NASDAQ National Market System ("NASDAQ NMS") security
  or is included in the OTC Bulletin Board Service ("OTC Bulletin Board")
  operated by the National Association of Securities Dealers, Inc. (the "NASD"),
  Market Price means (i) the last reported sale price, regular way, on such day
  on the principal United States securities exchange registered under the
  Securities Exchange Act of 1934 on which such Portfolio Security is listed or
  admitted to trading, or (ii) if not listed or admitted to trading on any such
  securities exchange or if such last reported sale price is not obtainable, the
  last reported sale price on the over-the-counter market as reported on the
  NASDAQ NMS or OTC Bulletin Board on such day, or (iii) if the last reported
  sale price is not available pursuant to (i) and (ii) above, the mean of the
  last reported bid and offer price on the over-the-counter market as reported
  on the NASDAQ NMS or OTC Bulletin Board on such day as determined by the
  Calculation Agent.  The term "NASDAQ NMS security" shall include a security
  included in any successor to such system and the term "OTC Bulletin Board
  Service" shall include any successor service thereto.

  (b) If the Portfolio Security is not listed on a national securities exchange
  in the United States or is not a NASDAQ NMS security or included in the OTC
  Bulletin Board operated by the NASD, Market Price means the last reported sale
  price on such day on the securities exchange on which such Portfolio Security
  is listed or admitted to trading with the greatest volume of trading for the
  calendar month preceding such day as determined by the Calculation Agent,
  provided that if such last reported sale price is for a transaction which
  occurred more than four hours prior to the close of such exchange, then the
  Market Price shall mean the average (mean) of the last available bid and offer
  price on such exchange.  If such Portfolio Security is not listed or admitted
  to trading on any such securities exchange or if such last reported sale price
  or bid and offer are not obtainable, the Market Price shall mean the last
  reported sale price on the over-the-counter market with the greatest volume of
  trading as determined by the Calculation Agent, provided that if such last
  reported sale price is for a transaction which occurred more than four hours
  prior to when trading in such over-the-counter market typically ends, then the
  Market Price shall mean the average (mean) of the last available bid and offer
  prices in such market of the three dealers which have the highest volume of
  transactions in such Portfolio Security in the immediately preceding calendar
  month as determined by the Calculation Agent based on information that is
  reasonably available to it.  If such prices are quoted in a currency other
  than in U.S.  Dollars, such prices will be translated into U.S. Dollars for
  purposes of calculating the Average Market Price using the Spot Rate on the
  same calendar day as the date of any such price.  The "Spot Rate" on any date
  will be determined by the Calculation Agent and will equal the spot rate of
  such currency per U.S. $1.00 on such date at approximately 3:00 p.m., New York
  City time, as reported on the information service operated by Bloomberg, L.P.
  ("Bloomberg") representing the mean of certain dealers in such currency or, if
  Bloomberg has not reported such rate by 3:30 p.m., New York City time, on such
  day, the offered spot rate of such currency per U.S. $1.00 on such date for a
  transaction amount in an amount customary for such market on such date quoted
  at approximately 3:30 p.m., New York City time, by a leading bank in the
  foreign exchange markets as may be selected by the Calculation Agent.

  If the Calculation Agent is required to use the bid and offer price for a
Portfolio Security to determine the Market Price of such Portfolio Security
pursuant to the foregoing, the Calculation Agent shall not use any bid or offer
price announced by MLPF&S or any other affiliate of the Company.

  As used herein, "NYSE Trading Day" shall mean a day on which trading is
generally conducted in the over-the-counter market for equity securities in the
United States and on the New York Stock Exchange as determined by the
Calculation Agent.  "Trading Day" shall mean a day on which trading is conducted
on the principal securities exchanges in the country in which such Portfolio
Security is being priced.

                                       8
<PAGE>
 
  "Market Disruption Event" with respect to a Portfolio Security means either of
the following events, as determined by the Calculation Agent:

  (i) the suspension or material limitation (provided that, with respect to
  Portfolio Securities that are priced in the United States, limitations
  pursuant to New York Stock Exchange Rule 80A (or any applicable rule or
  regulation enacted or promulgated by the New York Stock Exchange, any other
  self regulatory organization or the Commission of similar scope as determined
  by the Calculation Agent) on trading during significant market fluctuations
  shall be considered "material" for purposes of this definition) in the trading
  of such Portfolio Security in the country in which such Portfolio Security is
  being priced for more than two hours of trading or during the period one-half
  hour prior to the time that such Portfolio Security is to be priced, or

  (ii) the suspension or material limitation (whether by reason of movements in
  price otherwise exceeding levels permitted by the relevant exchange or
  otherwise) in option contracts related to a Portfolio Security traded on any
  exchange in the country in which such Portfolio Security is being priced for
  more than two hours of trading or during the period one-half hour prior to the
  time that such Portfolio Security is to be priced.

  For the purposes of this definition, a limitation on the hours in a trading
day and/or number of days of trading will not constitute a Market Disruption
Event if it results from an announced change in the regular business hours of
the relevant exchange.  Under certain circumstances, the duties of MLPF&S as
Calculation Agent in determining the existence of Market Disruption Events could
conflict with the interests of MLPF&S as an affiliate of the issuer of the
Securities, Merrill Lynch & Co., Inc., and with the interests of beneficial
owners of the Securities.

  All determinations made by the Calculation Agent shall be at the sole
discretion of the Calculation Agent and, in the absence of manifest error, shall
be conclusive for all purposes and binding on the Company and beneficial owners
of the Securities.  All percentages resulting from any calculation on the
Securities will be rounded to the nearest one hundred-thousandth of a percentage
point, with five one-millionths of a percentage point rounded upwards (e.g.,
9.876545% (or .09876545) would be rounded to 9.87655% (or .0987655)), and all
dollar amounts used in or resulting from such calculation will be rounded to the
nearest cent with one-half cent being rounded upwards.

Portfolio Securities

  The securities listed below were used to calculate the Original Portfolio
Value.  Holders of the MITTS will not have any right to receive the Portfolio
Securities or the Underlying Shares.  The following table sets forth the
Portfolio Securities, the percentage of each Portfolio Security in the Original
Portfolio Value and their Initial Multipliers:

     The initial Multiplier relating to each Portfolio Security indicates the
number of such Portfolio Security, given the market price of such Portfolio
Security, required to be included in the calculation of the Original Portfolio
Value so that each Portfolio Security represents an equal percentage of the
Original Portfolio Value on December 22, 1993.  The price of each Portfolio
Security used to calculate the initial Multiplier relating to each such
Portfolio Security was the closing price of such Portfolio Security on December
22, 1993.  The respective Multipliers will remain constant for the term of the
Securities unless adjusted for certain corporate events, as described below.

     The Portfolio Value, for any day, will equal the sum of the products of the
most recently available Market Prices (determined as described herein) and the
applicable Multipliers for the Portfolio Securities.  The Closing Portfolio
Value, however, is calculated based on averaging Market Prices for certain days.

     The Calculation Agent currently intends to publish the Portfolio Value once
on each business day.  The Calculation Agent currently calculates and publishes
values of approximately 1,100 specified portfolios.  The Calculation Agent
currently provides information concerning such portfolios to the electronic
reporting services operated by Bloomberg and to newspapers and specialized trade
publications.  If the Calculation Agent does publish Portfolio Values, the
Calculation Agent currently intends to provide such values to similar sources
described above, but there can be no assurance that such information will
ultimately be published by such sources.  In addition, the Calculation Agent
will provide the Portfolio Value upon request, and will provide the Portfolio
Value once each business day to the New York Stock Exchange which has agreed to
report such Portfolio Value on its electronic transaction reporting services
under the symbol "MEP".

ADJUSTMENTS TO THE MULTIPLIER AND PORTFOLIO

     The Multiplier with respect to any Portfolio Security and the Portfolio
will be adjusted as follows:

          1.  If a Portfolio Security is subject to a stock split or reverse
     stock split or a Portfolio Security that is an ADR is subject to a similar
     adjustment, then once such split has become effective, the Multiplier
     relating to such Portfolio Security will be adjusted to equal the product
     of the number of shares issued with respect to one such share of such
     Portfolio Security, or the number of receipts issued with respect to one
     ADR if a Portfolio Security is an ADR, and the prior multiplier.

          2.  If a Portfolio Security is subject to a stock dividend (issuance
     of additional shares of the Portfolio Security) that is given equally to
     all holders of shares of the issuer of such Portfolio Security, then once
     the dividend has become effective and such Portfolio Security is trading
     ex-dividend, the Multiplier will be adjusted so that the new Multiplier
     shall equal the former Multiplier plus the product of the number of shares
     of such Portfolio Security issued with respect to one such share of such
     Portfolio Security and the prior multiplier.

          3.  There will be no adjustments to the Multipliers to reflect cash
     dividends or distributions paid with respect of a Portfolio Security other
     than for Extraordinary Dividends as described below.  A cash dividend with
     respect to a Portfolio Security will be deemed to be an "Extraordinary
     Dividend" if such dividend exceeds the immediately preceding non-
     Extraordinary Dividend for such Portfolio Security by an amount equal to at
     least 10% of the Market Price on the Trading Day preceding the record day
     for the payment of such Extraordinary Dividend (the "ex-dividend date").
     If an Extraordinary Dividend occurs with respect to a Portfolio Security,
     the Multiplier with respect to such Portfolio Security will be adjusted on
     the ex-dividend date with respect to such Extraordinary Dividend so that
     the new Multiplier will equal the product of (i) the then current
     Multiplier, and (ii) a fraction, the numerator of which is the sum of the
     Extraordinary Dividend Amount and the Market Price on the Trading Day
     preceding the ex-dividend date, and the denominator of which is the Market
     Price on the Trading Day preceding the ex-dividend date.  The
     "Extraordinary Dividend Amount" with respect to an Extraordinary Dividend
     for a Portfolio Security will equal such Extraordinary Dividend minus the
     amount of the immediately preceding non-Extraordinary Dividend for such
     Portfolio Security.

                                       11
<PAGE>
 
     4. If the issuer of a Portfolio Security, or, if a Portfolio Security is an
     ADR, the issuer of the Underlying Share, is being liquidated or is subject
     to a proceeding under any applicable bankruptcy, insolvency or other
     similar law, such Portfolio Security will continue to be included in the
     Portfolio so long as a Market Price for such Portfolio Security is
     available.  If a Market Price is no longer available for a Portfolio
     Security for whatever reason, including the liquidation of the issuer of
     such Portfolio Security or the subjection of the issuer of such Portfolio
     Security to a proceeding under any applicable bankruptcy, insolvency or
     other similar law, then the value of such Portfolio Security will equal
     zero in connection with calculating Portfolio Value and Closing Portfolio
     Value for so long as no Market Price is available, and no attempt will be
     made to find a replacement stock or increase the value of the Portfolio to
     compensate for the deletion of such Portfolio Security.

          5.  If the issuer of a Portfolio Security, or, if a Portfolio Security
     is an ADR, the issuer of the Underlying Share, has been subject to a merger
     or consolidation and is not the surviving entity or is nationalized, then a
     value for such Portfolio Security will be determined at the time such
     issuer is merged or consolidated or nationalized and will equal the last
     available Market Price for such Portfolio Security and that value will be
     constant for the remaining term of the Securities.  At such time, no
     adjustment will be made to the Multiplier of such Portfolio Security.  The
     Company may at its sole discretion increase such last available Market
     Price to reflect payments or dividends of cash, securities or other
     consideration to holders of such Portfolio Security in connection with such
     a merger or consolidation which may not be reflected in such last available
     Market Price.

          6.  If the issuer of a Portfolio Security issues to all of its
     shareholders equity securities of an issuer other than the issuer of the
     Portfolio Security, then such new equity securities will be added to the
     Portfolio as a new Portfolio Security.  The Multiplier for such new
     Portfolio Security will equal the product of the original Multiplier with
     respect to the Portfolio Security for which the new Portfolio Security is
     being issued (the "Original Portfolio Security") and the number of shares
     of the new Portfolio Security issued with respect to one share of the
     Original Portfolio Security.

          7.  If an ADR is no longer listed or admitted to trading on a United
     States securities exchange registered under the Exchange Act, is no longer
     a NASDAQ NMS security or is no longer included in the OTC Bulletin Board
     operated by the NASD, then the Underlying Shares represented by such ADR
     will be deemed to be a new Portfolio Security and such ADR will no longer
     constitute a Portfolio Security.  The initial Multiplier for such new
     Portfolio Security will equal the last value of the Multiplier for such ADR
     multiplied by the number of shares of Underlying Shares represented by a
     single ADR.

     No adjustments of any Multiplier of a Portfolio Security will be required
unless such adjustment would require a change of at least 1% in the Multiplier
then in effect.  The Multiplier resulting from any of the adjustments specified
above will be rounded to the nearest one thousandth with five ten-thousandths
being rounded upward.

     No adjustments to the Multiplier of any Portfolio Security or to the
Portfolio will be made other than those specified above.

HYPOTHETICAL PAYMENTS

     The following table illustrates, for a range of hypothetical Closing
Portfolio Values, the amount payable at maturity for each Unit of Securities.
AN INVESTMENT IN THE PORTFOLIO SECURITIES WOULD BE SIGNIFICANTLY DIFFERENT THAN
INVESTING IN THE SECURITIES.  AMONG OTHER THINGS, AN INVESTOR IN THE PORTFOLIO
SECURITIES MAY REALIZE CERTAIN DIVIDENDS THAT ARE NOT REFLECTED BY INVESTING IN
THE SECURITIES, AND CURRENCY FLUCTUATIONS MAY SIGNIFICANTLY INCREASE OR DECREASE
THE RATE OF RETURN OF THE PORTFOLIO SECURITIES VERSUS INVESTING IN THE
SECURITIES.

     The above figures are for purposes of illustration only.  The actual amount
payable at maturity with respect to the Securities will depend entirely on the
actual Closing Portfolio Value.

     The investor will not receive their entire principal at maturity should the
Portfolio decline in value.  The investor will only receive $9.00 for each $10
principal amount of Securities (90% of their original investment) should the
Portfolio decline in value by 10% or more.

EVENTS OF DEFAULT AND ACCELERATION

     In case an Event of Default with respect to any Securities shall have
occurred and be continuing, the amount payable to a Holder of a Security upon
any acceleration permitted by the Securities will be equal to the amount payable
calculated as though the date of early repayment were the maturity date of the
Securities.  See "Description of Securities--Payment at Maturity" in this
Prospectus.  If a bankruptcy proceeding is commenced in respect of the Company,
the claim of the Holder of a Security may be limited, under Section 502(b)(2) of
Title 11 of the United States Code, to the principal amount of the Security plus
an additional amount, if any, of contingent interest calculated as though the
date of the commencement of the proceeding were the maturity date of the
Securities.

                                       13
<PAGE>
 
     In case of default in payment at the maturity date of the Securities
(whether at their stated maturity or upon acceleration), from and after the
maturity date the Securities shall bear interest, payable upon demand of the
Holders thereof, at the rate of 6% per annum (to the extent that payment of such
interest shall be legally enforceable) on the unpaid amount due and payable on
such date in accordance with the terms of the Securities to the date payment of
such amount has been made or duly provided for.

SECURITIES DEPOSITORY

     The Securities are represented by one fully registered global security (the
"Global Security").  Such Global Security has been deposited with, or on behalf
of, The Depository Trust Company, as Securities Depository (the "Securities
Depository), registered in the name of the Securities Depository or a nominee
thereof.  Unless and until it is exchanged in whole or in part for Securities in
definitive form, the Global Security may not be transferred except as a whole by
the Securities Depository to a nominee of such Securities Depository or by a
nominee of such Securities Depository to such Securities Depository or another
nominee of such Securities Depository or by such Securities Depository or any
such nominee to a successor of such Securities Depository or a nominee of such
successor.

     The Securities Depository has advised the Company as follows: The
Securities Depository is a limited-purpose trust company organized under the
Banking Law of the State of New York, a member of the Federal Reserve System, a
"clearing corporation" within the meaning of the New York Uniform Commercial
Code, and a "clearing agency" registered pursuant to the provisions of Section
17A of the Exchange Act.  The Securities Depository was created to hold
securities of its participants ("Participants") and to facilitate the clearance
and settlement of securities transactions among its Participants in such
securities through electronic book-entry changes in accounts of the
Participants, thereby eliminating the need for physical movement of securities
certificates.  The Securities Depository's Participants include securities
brokers and dealers, banks, trust companies, clearing corporations, and certain
other organizations.

     The Securities Depository is owned by a number of Participants and by the
New York Stock Exchange, Inc., the American Stock Exchange, Inc. and the NASD.
Access to the Securities Depository book-entry system is also available to
others, such as banks, brokers, dealers and trust companies that clear through
or maintain a custodial relationship with a Participant, either directly or
indirectly ("Indirect Participants").

     Purchases of Securities must be made by or through Participants, which will
receive a credit on the records of the Securities Depository.  The ownership
interest of each actual purchaser of each Security ("Beneficial Owner") is in
turn to be recorded on the Participants' or Indirect Participants' records.
Beneficial Owners will not receive written confirmation from the Securities
Depository of their purchase, but Beneficial Owners are expected to receive
written confirmations providing details of the transaction, as well as periodic
statements of their holdings, from the Participant or Indirect Participant
through which the Beneficial Owner entered into the transaction.  Ownership of
beneficial interests in such Global Security will be shown on, and the transfer
of such ownership interests will be effected only through, records maintained by
the Securities Depository (with respect to interests of Participants) and on the
records of Participants (with respect to interests of persons held through
Participants).  The laws of some states may require that certain purchasers of
securities take physical delivery of such securities in definitive form.  Such
limits and such laws may impair the ability to own, transfer or pledge
beneficial interests in Global Securities.

     So long as the Securities Depository, or its nominee, is the registered
owner of the Global Security, the Securities Depository or its nominee, as the
case may be, will be considered the sole owner or Holder of the Securities
represented by such Global Security for all purposes under the Senior Indenture.
Except as provided below, Beneficial Owners in the Global Security will not be
entitled to have the Securities represented by such Global Security registered
in their names, will not receive or be entitled to receive physical delivery of
the Securities in definitive form and will not be considered the owners or
Holders thereof under the Senior Indenture.  Accordingly, each Person owning a
beneficial interest in a Global Security must rely on the procedures of the
Securities Depository and, if such Person is not a Participant, on the
procedures of the Participant through which such Person owns its interest, to
exercise any rights of a Holder under the Senior Indenture.  The Company
understands that

                                       14
<PAGE>
 
under existing industry practices, in the event that the Company requests any
action of Holders or that an owner of a beneficial interest in the Global
Security desires to give or take any action which a Holder is entitled to give
or take under the Senior Indenture, the Securities Depository would authorize
the Participants holding the relevant beneficial interests to give or take such
action, and such Participants would authorize Beneficial Owners owning through
such Participants to give or take such action or would otherwise act upon the
instructions of beneficial owners.  Conveyance of notices and other
communications by the Securities Depository to Participants, by Participants to
Indirect Participants, and by Participants and Indirect Participants to
Beneficial Owners will be governed by arrangements among them, subject to any
statutory or regulatory requirements as may be in effect from time to time.

     Payment of the principal of, and any additional amount payable at maturity
with respect to, Securities registered in the name of the Securities Depository
or its nominee will be made to the Securities Depository or its nominee, as the
case may be, as the Holder of the Global Security representing such Securities.
None of the Company, the Trustee or any other agent of the Company or agent of
the Trustee will have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership
interests or for supervising or reviewing any records relating to such
beneficial ownership interests.  The Company expects that the Securities
Depository, upon receipt of any payment of principal or any additional amount
payable at maturity in respect of the Global Security, will credit the accounts
of the Participants with payment in amounts proportionate to their respective
holdings in principal amount of beneficial interest in such Global Security as
shown on the records of the Securities Depository.  The Company also expects
that payments by Participants to Beneficial Owners will be governed by standing
customer instructions and customary practices, as is now the case with
securities held for the accounts of customers in bearer form or registered in
"street name", and will be the responsibility of such Participants.

     If (x) the Securities Depository is at any time unwilling or unable to
continue as Securities Depository and a successor depository is not appointed by
the Company within 60 days, (y) the Company executes and delivers to the Trustee
a Company Order to the effect that the Global Security shall be exchangeable or
(z) an Event of Default has occurred and is continuing with respect to the
Securities, the Global Security will be exchangeable for Securities in
definitive form of like tenor and of an equal aggregate principal amount, in
denominations of $10 and integral multiples thereof.  Such definitive Securities
shall be registered in such name or names as the Securities Depository shall
instruct the Trustee.  It is expected that such instructions may be based upon
directions received by the Securities Depository from Participants with respect
to ownership of beneficial interests in such Global Security.


                                 THE PORTFOLIO
                                        
GENERAL

     While the Portfolio consists of stocks (or ADRs representing interests
therein) of European issuers, the Portfolio is not intended to provide an
indication of the pattern of price movements of common stocks of European
corporations generally.  As of December 22, 1993, all of the Portfolio
Securities were registered under the Exchange Act, except for the Portfolio
Securities which are ADRs representing shares in Bayer A.G., Deutsche Bank A.G.,
Hoechst A.G., Siemens A.G. and Nestle S.A.  Companies with securities registered
under the Exchange Act are required to file periodically certain financial and
other information specified by the Commission (including a reconciliation of
their financial statements to United States generally accepted accounting
principles).  As of December 22, 1993, Bayer A.G., Deutsche Bank A.G., Hoechst
A.G., Siemens A.G. and Nestle S.A. had qualified for an exemption from the
reporting requirements of the Exchange Act and had agreed to provide to the
Commission certain financial and other information that the issuer provides to
its shareholders or files with stock exchanges in its home country or is
otherwise required to make public.  Such information is not required to contain
a reconciliation of their financial statements to United States generally
accepted accounting principles.  Information provided to or filed with the
Commission is available at the offices of the Commission specified under
"Available Information" in this Prospectus.  Information contained in such
information filed with the Commission will generally be more limited than that
available with respect to a United States issuer.  The Company makes no
representation

                                       15
<PAGE>
 
or warranty as to the accuracy or completeness of such reports.  THE INCLUSION
OF A PORTFOLIO SECURITY IN THE PORTFOLIO IS NOT A RECOMMENDATION TO BUY OR SELL
SUCH PORTFOLIO SECURITY OR THE UNDERLYING SHARES RELATING THERETO, AND NEITHER
THE COMPANY NOR ANY OF ITS AFFILIATES MAKE ANY REPRESENTATION TO ANY PURCHASER
OF SECURITIES AS TO THE PERFORMANCE OF THE PORTFOLIO.

     The Company or its affiliates may presently or from time to time engage in
business with one or more of the issuers of the Portfolio Securities or of the
Underlying Shares relating to the Portfolio Securities, including extending
loans to, or making equity investments in, such issuers or providing advisory
services to such issuers, including merger and acquisition advisory services.
In the course of such business, the Company or its affiliates may acquire non-
public information with respect to such issuers and, in addition, one or more
affiliates of the Company may publish research reports with respect to such
issuers.  The Company does not make any representation to any purchaser of
Securities with respect to any matters whatsoever relating to such issuers.  Any
prospective purchaser of a Security should undertake an independent
investigation of the issuers of the Underlying Shares relating to the Portfolio
Securities as in its judgment is appropriate to make an informed decision with
respect to an investment in the Securities.


EUROPE

     The issuers of the Portfolio Securities, or of the shares underlying the
Portfolio Securities which are ADRs, are companies which have been organized in
countries located in Europe.  The amount payable at the maturity of the
Securities is dependent on the value of such Portfolio Securities and the value
of such Portfolio Securities will be affected by political and economic
developments in Europe.

     The economies of individual European countries may differ favorably or
unfavorably from the U.S.  economy in such respects as growth of gross domestic
product, rate of inflation, capital reinvestment, resource self-sufficiency and
balance of payments position.  European countries in recent years generally have
experienced weak economic performance and suffer from relatively high
unemployment levels, slow growth, falling industrial competitiveness, and
increasing costs for social welfare programs.

     The securities markets of most European countries have substantially less
trading volume than the securities markets of the United States and Japan.
Further, securities of some European companies are less liquid and more volatile
than securities of comparable U.S. companies.  Accordingly, European securities
markets may be subject to greater influence by adverse events generally
affecting the market, and by large investors trading significant blocks of
securities or by large dispositions of securities than is the case in the United
States.

ISSUERS OF THE UNDERLYING SHARES

     Among the issuers of Portfolio Securities and the Underlying Shares, 9 are
incorporated in the United Kingdom, 4 in the Federal Republic of Germany, 4 in
France, 2 in the Netherlands, 2 in Spain, 1 in Italy, 1 in Sweden and 1 in
Switzerland.  The following table sets forth the issuers of the Portfolio
Securities and Underlying Shares, the country in which each such issuer is
organized and the primary industry in which each such issuer is engaged:

     A potential investor should review the historical prices of the securities
underlying the Portfolio. The historical prices of such securities should not be
taken as an indication of future performance, and no assurance can be given that
the prices of such securities will increase sufficiently to cause the beneficial
owners of the Securities to receive an amount in excess of the Minimum Payment
at the maturity of the Securities.


                                  OTHER TERMS

GENERAL

     The Securities were issued as a series of Senior Debt Securities under the
Indenture (the "Senior Indenture"), dated as of April 1, 1983, as amended and
restated, between the Company and The Chase Manhattan Bank, formerly known as
Chemical Bank (successor by merger to Manufacturers Hanover Trust Company), as
trustee (the "Trustee"). A copy of the Senior Indenture is filed as an exhibit
to the registration statements relating to the Securities. The following
summaries of certain provisions of the Senior Indenture do not purport to be
complete and are subject to, and qualified in their entirety by reference to,
all provisions of the Senior Indenture, including the definition therein of
certain terms.

     The Senior Indenture provides that series of Senior Debt Securities may
from time to time be issued thereunder, without limitation as to aggregate
principal amount, in one or more series and upon such terms as the Company may
establish pursuant to the provisions thereof.

     The Senior Indenture provides that the Senior Indenture and the Securities
are governed by and construed in accordance with the laws of the State of New
York.

                                       17
<PAGE>
 
     The Senior Indenture provides that the Company may issue Senior Debt
Securities with terms different from those of Senior Debt Securities previously
issued, and "reopen" a previously issued series of Senior Debt Securities and
issue additional Senior Debt Securities of such series.

     The Senior Debt Securities are unsecured and rank pari passu with all other
unsecured and unsubordinated indebtedness of the Company.  However, since the
Company is a holding company, the right of the Company, and hence the right of
creditors of the Company (including the Holders of Senior Debt Securities), to
participate in any distribution of the assets of any subsidiary upon its
liquidation or reorganization or otherwise is necessarily subject to the prior
claims of creditors of the subsidiary, except to the extent that claims of the
Company itself as a creditor of the subsidiary may be recognized.  In addition,
dividends, loans and advances from certain subsidiaries, including MLPF&S, to
the Company are restricted by net capital requirements under the Exchange Act
and under rules of certain exchanges and other regulatory bodies.

LIMITATIONS UPON LIENS

     The Company may not, and may not permit any Subsidiary to, create, assume,
incur or permit to exist any indebtedness for borrowed money secured by a
pledge, lien or other encumbrance (except for certain liens specifically
permitted by the Senior Indenture) on the Voting Stock owned directly or
indirectly by the Company of any Subsidiary (other than a Subsidiary which, at
the time of the incurrence of such secured indebtedness, has a net worth of less
than $3,000,000) without making effective provision whereby the Outstanding
Senior Debt Securities will be secured equally and ratably with such secured
indebtedness.

LIMITATION ON DISPOSITION OF VOTING STOCK OF, AND MERGER AND SALE OF ASSETS BY,
MLPF&S

     The Indenture provides that the Company may not sell, transfer or otherwise
dispose of any Voting Stock of MLPF&S or permit MLPF&S to issue, sell or
otherwise dispose of any of its Voting Stock, unless, after giving effect to any
such transaction, MLPF&S remains a Controlled Subsidiary (defined in the Senior
Indenture to mean a corporation more than 80% of the outstanding shares of
Voting Stock of which are owned directly or indirectly by the Company).  In
addition, the Company may not permit MLPF&S to (i) merge or consolidate, unless
the surviving company is a Controlled Subsidiary or (ii) convey or transfer its
properties and assets substantially as an entirety, except to one or more
Controlled Subsidiaries.

MERGER AND CONSOLIDATION

     The Indenture provides that the Company may consolidate or merge with or
into any other corporation, and the Company may sell, lease or convey all or
substantially all of its assets to any corporation, provided that (i) the
corporation (if other than the Company) formed by or resulting from any such
consolidation or merger or which shall have received such assets shall be a
corporation organized and existing under the laws of the United States of
America or a state thereof and shall assume payment of the principal of (and
premium, if any) and interest on the Senior Debt Securities and the performance
and observance of all of the covenants and conditions of the Senior Indenture to
be performed or observed by the Company, and (ii) the Company or such successor
corporation, as the case may be, shall not immediately thereafter be in default
under the Senior Indenture.

MODIFICATION AND WAIVER

     Modification and amendment of the Indenture may be effected by the Company
and the Trustee with the consent of the Holders of 66 2/3% in principal amount
of the Outstanding Senior Debt Securities of each series issued pursuant to such
indenture and affected thereby, provided that no such modification or amendment
may, without the consent of the Holder of each Outstanding Senior Debt Security
affected thereby, (a) change the Stated Maturity of the principal of, or any
installment of interest or Additional Amounts payable on, any Senior Debt
Security or any premium payable on the redemption thereof, or change the
Redemption Price; (b) reduce the principal amount of, or the interest or
Additional Amounts payable on, any Senior Debt Security or reduce the amount of
principal which could be declared due and payable prior to the Stated Maturity;
(c) change place or

                                       18
<PAGE>
 
currency of any payment of principal or any premium, interest or Additional
Amounts payable on any Senior Debt Security; (d) impair the right to institute
suit for the enforcement of any payment on or with respect to any Senior Debt
Security; (e) reduce the percentage in principal amount of the Outstanding
Senior Debt Securities of any series, the consent of whose Holders is required
to modify or amend the Indenture; or (f) modify the foregoing requirements or
reduce the percentage of Outstanding Senior Debt Securities necessary to waive
any past default to less than a majority.  No modification or amendment of the
Subordinated Indenture or any Subsequent Indenture for Subordinated Debt
Securities may adversely affect the rights of any holder of Senior Indebtedness
without the consent of such Holder.  Except with respect to certain fundamental
provisions, the Holders of at least a majority in principal amount of
Outstanding Senior Debt Securities of any series may, with respect to such
series, waive past defaults under the Indenture and waive compliance by the
Company with certain provisions thereof.

EVENTS OF DEFAULT

     Under the Senior Indenture, the following will be Events of Default with
respect to Senior Debt Securities of any series: (a) default in the payment of
any interest or Additional Amounts payable on any Senior Debt Security of that
series when due, continued for 30 days; (b) default in the payment of any
principal or premium, if any, on any Senior Debt Security of that series when
due; (c) default in the deposit of any sinking fund payment, when due, in
respect of any Senior Debt Security of that series; (d) default in the
performance of any other covenant of the Company contained in the Indenture for
the benefit of such series or in the Senior Debt Securities of such series,
continued for 60 days after written notice as provided in the Senior Indenture;
(e) certain events in bankruptcy, insolvency or reorganization; and (f) any
other Event of Default provided with respect to Senior Debt Securities of that
series.  The Trustee or the Holders of 25% in principal amount of the
Outstanding Senior Debt Securities of that series may declare the principal
amount (or such lesser amount as may be provided for in the Senior Debt
Securities of that series) of all Outstanding Senior Debt Securities of that
series and the interest due thereon and Additional Amounts payable in respect
thereof, if any to be due and payable immediately if an Event of Default with
respect to Senior Debt Securities of such series shall occur and be continuing
at the time of such declaration.  At any time after a declaration of
acceleration has been made with respect to Senior Debt Securities of any series
but before a judgment or decree for payment of money due has been obtained by
the Trustee, the Holders of a majority in principal amount of the Outstanding
Senior Debt Securities of that series may rescind any declaration of
acceleration and its consequences, if all payments due (other than those due as
a result of acceleration) have been made and all Events of Default have been
remedied or waived.  Any Event of Default with respect to Senior Debt Securities
of any series may be waived by the Holders of a majority in principal amount of
all Outstanding Senior Debt Securities of that series, except in a case of
failure to pay principal or premium, if any, or interest or Additional Amounts
payable on any Senior Debt Security of that series for which payment had not
been subsequently made or in respect of a covenant or provision which cannot be
modified or amended without the consent of the Holder of each Outstanding Senior
Debt Security of such series affected.

     The Holders of a majority in principal amount of the Outstanding Senior
Debt Securities of a series may 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 Senior Debt Securities of such
series, provided that such direction shall not be in conflict with any rule of
law or the Senior Indenture.  Before proceeding to exercise any right or power
under the Senior Indenture at the direction of such Holders, the Trustee shall
be entitled to receive from such Holders reasonable security or indemnity
against the costs, expenses and liabilities which might be incurred by it in
complying with any such direction.

     The Company is required to furnish to the Trustee annually a statement as
to the fulfillment by the Company of all of its obligations under the Senior
Indenture.

  On April 29, 1993, Merrill Lynch & Co., Inc. (the "Company") issued
$50,000,000 aggregate principal amount of Stock Market Annual Reset Term Notes
(Series A) due December 31, 1999 (the "Notes" or "SMART Notes"). As of the date
of this Prospectus, $20,000,000 aggregate principal amount of the Notes remain
outstanding.  The Notes were issued in denominations of $1,000 and integral
multiples thereof and will mature and be repayable at 100% of the principal
amount thereof on December 31, 1999. The Notes are not subject to redemption
prior to maturity.

  The Company will make interest payments on the Notes for each year at a rate
per annum equal to the Participation Rate multiplied by the percent increase, if
any, in the S&P MidCap 400 Composite Stock Price Index as determined in each
year as further described herein (the "Annual Percent Appreciation"). Annual
payments will in no event be less than the Minimum Annual Payment or more than
the Maximum Annual Payment. The table below specifies the Minimum Annual Payment
and the Maximum Annual Payment on a per annum basis per $1,000 principal amount
of Notes as well as the Participation Rate.  Interest payments will be payable
on June 30 and December 31 of each year.

       Minimum Annual Payment..................    $30 (3%)
       Maximum Annual Payment..................   $100 (10%)

debt expense, preferred stock dividend requirements of majority-owned
subsidiaries, and that portion of rentals estimated to be representative of the
interest factor.


                                  RISK FACTORS

INTEREST PAYMENTS

  If the Ending Annual Value applicable to a December Payment Date does not
exceed the Starting Annual Value applicable to such December Payment Date by
more than approximately 4.62%, beneficial owners of the Notes will receive only
the Minimum Annual Payment on such December Payment Date, even if the value of
the S&P MidCap 400 Index at some point between the determination of the
applicable Starting Annual Value and the determination of the applicable Ending
Annual Value exceeded such Starting Annual Value by more than approximately
4.62%. The annual amount payable on the Notes based on the S&P MidCap 400 Index
is limited to the Participation Rate multiplied by the percent increase in such
index during the period between the date of the determination of the applicable
Starting Annual Value for such year and the date of the determination of the
applicable Ending Annual Value for such year, and in no event will such amount
exceed the Maximum Annual Payment. If the Ending Annual Value applicable to a
December Payment Date exceeds the Starting Annual Value applicable to such
December Payment Date by more than approximately 15.38%, the beneficial owners
of the Notes would receive only the Maximum Annual Payment for the applicable
payment period.

  Beneficial owners of the Notes will receive total annual payments equal to not
less than the Minimum Annual Payment, and will be repaid 100% of the principal
amount of the Notes at maturity. Beneficial owners of Notes may receive interest
payments with respect to the Notes equal to only the Minimum Annual Payment for
each year, and such interest payments are below what the Company would pay as
interest as of the date of issuance if the Company issued non-callable senior
debt securities with a similar maturity as that of the Notes. The payment of
additional amounts on the Notes is subject to the conditions described under
"Description of Notes--Interest Payments". The return of principal of the Notes
at maturity and the payment of the Minimum Annual Payment are not expected to
reflect the full opportunity costs implied by inflation or other factors
relating to the time value of money.

  The amount payable on the Notes based on the S&P MidCap 400 Index will not
produce the same return as if the underlying stocks underlying the S&P MidCap
400 Index were purchased and held for a similar period because of the following:
(i) the S&P MidCap 400 Index does not reflect the payment of dividends on the
stocks underlying it, (ii) the amounts payable on the Notes do not reflect any
changes in the S&P MidCap 400 Index for the period between the determination of
an Ending Annual Value and the determination of the next succeeding Starting
Annual Value, and (iii), the annual amount payable is limited to 65% of the
percentage increase in the S&P MidCap 400 Index during any relevant period,
subject to the Minimum Annual Payment and the Maximum Annual Payment.

TRADING

  The Notes have been listed on the New York Stock Exchange under the symbol
"MERIQ 99".  It is expected that the secondary market for the Notes (including
prices in such market) will likely be affected by the creditworthiness of the
Company and by a number of other factors. It is possible to view the Notes as
the economic equivalent of a debt obligation plus a series of cash settlement
options; however, there can be no assurance that the Notes will not trade in the
secondary market at a discount from the aggregate value of such economic
components, if such economic components were valued and capable of being traded
separately.

  The trading values of the Notes may be affected by a number of interrelated
factors, including those listed below. The following is the expected theoretical
effect on the trading value of the Notes of each of the factors listed

                                       4
<PAGE>
 
below. The following discussion of each separate factor generally assumes that
all other factors are held constant, although the actual interrelationship
between certain of such factors is complex.

  Relative Level of the S&P MidCap 400 Index. The trading value of the Notes is
  expected to depend significantly on the extent of the appreciation, if any, of
  the S&P MidCap 400 Index over the Annual Starting Value applicable to the next
  succeeding December Payment Date. If, however, Notes are sold at a time when
  the S&P MidCap 400 Index exceeds the Annual Starting Value, the sale price may
  nevertheless be at a discount from the amount expected to be payable to the
  beneficial owner if such excess were to prevail until the next December
  Payment Date. Furthermore, the price at which a beneficial owner will be able
  to sell Notes prior to a December Payment Date may be at a discount, which
  could be substantial, from the principal amount thereof, if, at such time, the
  S&P MidCap 400 Index is below, equal to or not sufficiently above the Annual
  Starting Value applicable to such December Payment Date. The value of the
  Notes may also be affected by the limitation of the applicable Maximum Annual
  Payment.

  Volatility of the S&P MidCap 400 Index. If the volatility of the S&P MidCap
  400 Index increases, the trading value of the Notes is expected to increase.
  If the volatility of the S&P MidCap 400 Index decreases, the trading value of
  the Notes is expected to decrease.

  U.S. Interest Rates. In general, if U.S. interest rates increase, the value of
  the Notes is expected to decrease. If U.S. interest rates decrease, the value
  of the Notes is generally expected to increase. Interest rates may also affect
  the U.S. economy, and, in turn, the level of the S&P MidCap 400 Index. Rising
  interest rates may lower the level of the S&P MidCap 400 Index and, thus, the
  value of the Notes. Falling interest rates may increase the level of the S&P
  MidCap 400 Index and, thus, may increase the value of the Notes.

  Time Remaining to December Payment Dates. The Notes may trade at a value above
  that which may be inferred from the level of U.S. interest rates and the S&P
  MidCap 400 Index. This difference will reflect a "time premium" due to
  expectations concerning the level of the S&P MidCap 400 Index during the
  period prior to each December Payment Date. As the time remaining to each
  December Payment Date decreases, however, this time premium may decrease, thus
  decreasing the trading value of the Notes.

  Time Remaining to Maturity. As the number of remaining December Payment Dates
  decreases, the cumulative value of all the annual rights to receive an amount
  that reflects participation in the appreciation of the S&P MidCap 400 Index
  above the Starting Annual Value (which would be realized in interest payments
  in excess of the Minimum Annual Payment) will decrease, thus decreasing the
  value of the Notes. Furthermore, as the time to maturity decreases, the value
  of the right to receive the Minimum Annual Payment and the principal amount is
  expected to increase, thus increasing the value of the Note.

  Dividend Rates. A number of complex relationships between the relative values
  of the Notes and dividend rates are likely to exist. If dividend rates on the
  stocks comprising the S&P MidCap 400 Index increase, the value of the annual
  right to receive an amount that reflects participation in the appreciation of
  the S&P MidCap 400 Index above the Starting Annual Value is expected to
  decrease. Consequently the value of the Notes is expected to decrease.
  Conversely, if dividend rates on the stocks comprising the S&P MidCap 400
  Index decrease, the value of the annual right to receive such an amount is
  expected to increase and, therefore, the value of the Notes is expected to
  increase. However, in general, rising U.S. corporate dividend rates may
  increase the S&P MidCap 400 Index and, in turn, increase the value of the
  Notes. Conversely, falling U.S. dividend rates may decrease the S&P MidCap 400
  Index and, in turn, decrease the value of the Notes.

OTHER CONSIDERATIONS

  It is suggested that prospective investors who consider purchasing the Notes
should reach an investment decision only after carefully considering the
suitability of the Notes in the light of their particular circumstances.

                                       5
<PAGE>
 
  Investors should also consider the tax consequences of investing in the Notes
and should consult their tax advisors.

                              DESCRIPTION OF NOTES

GENERAL

  The Notes were issued as a series of Senior Debt Securities under the Senior
Indenture, dated as of April 1, 1983, as amended and restated, which is more
fully described below. The Notes will mature, and the principal of the Notes
will be repayable at par, on December 31, 1999.

  The Notes are not subject to redemption prior to maturity by the Company or at
the option of any beneficial owner. Upon the occurrence of an Event of Default
with respect to the Notes, however, beneficial owners of the Notes or the Senior
Debt Trustee may accelerate the maturity of the Notes, as described under
"Description of Notes--Events of Default and Acceleration" and "Other Terms--
Events of Default" in this Prospectus.

  The Notes were issued in denominations of $1,000 and integral multiples
thereof.

INTEREST PAYMENTS

  For each full calendar year, the Company will pay interest in an amount equal
to the following for each $1,000 principal amount of Notes:

               $1,000 x Annual Percent Appreciation x Participation Rate

provided, however, that the per annum amount payable as a result of the
foregoing on the Notes will not be less than the Minimum Annual Payment or
greater than the Maximum Annual Payment. The table below specifies the Minimum
Annual Payment and the Maximum Annual Payment on a per annum basis per $1,000
principal amount of Notes as well as the Participation Rate.

          Minimum Annual Payment.......  $30  (3%)
          Maximum Annual Payment....... $100  (10%)
          Participation Rate...........    65%

  The "Annual Percent Appreciation" applicable to the determination of the
amount payable in any year will equal (i) the Ending Annual Value minus the
Starting Annual Value, divided by (ii) the Starting Annual Value. The "Starting
Annual Value" applicable to the determination of the amount payable in a
calendar year will equal the closing value of the S&P MidCap 400 Index on the
first NYSE Business Day (as defined herein) in such year on which a Market
Disruption Event has not occurred as determined by State Street Bank and Trust
Company (the "Calculation Agent"); provided, however, that if a Market
Disruption Event shall have occurred on each of the first ten NYSE Business Days
in any year, the "Starting Annual Value" applicable to the determination of the
amount payable in such year will equal the closing value of the S&P MidCap 400
Index on such tenth NYSE Business Day regardless of whether a Market Disruption
Event occurs on such day. The "Ending Annual Value" applicable to the
determination of the amount payable in a calendar year will equal the closing
value of the S&P MidCap 400 Index on the seventh scheduled NYSE Business Day
preceding the end of such year (including December 31 if it is a scheduled NYSE
Business Day) as determined by the Calculation Agent, unless a Market Disruption
Event has occurred on such day. In the event that a Market Disruption Event has
occurred on the seventh scheduled NYSE Business Day preceding the end of such
year, the "Ending Annual Value" applicable to the determination of the amount
payable in such year will equal the closing value of the S&P MidCap 400 Index on
the sixth scheduled NYSE Business Day preceding the end of such year regardless
of whether such day is a NYSE Business Day or a Market Disruption Event occurs
on such day. The Calculation Agent will determine the seventh scheduled NYSE
Business Day, and, if necessary, the sixth scheduled NYSE Business Day prior to
each December Payment Date.

                                       6
<PAGE>
 
  If the Ending Annual Value applicable to such December Payment Date does not
exceed the Starting Annual Value applicable to such December Payment Date by
more than approximately 4.62%, beneficial owners of the Notes will receive only
the Minimum Annual Payment on such December Payment Date, even if the value of
the S&P MidCap 400 Index at some point between the determination of the
applicable Starting Annual Value and the determination of the applicable Ending
Annual Value exceeded such Starting Annual Value by more than approximately
4.62%. If the Ending Annual Value applicable to a December Payment Date exceeds
the Starting Annual Value applicable to such December Payment Date by more than
approximately 15.38%, the beneficial owners of the Notes would receive only the
Maximum Annual Payment for the applicable payment period.

  Any day on which a Starting Annual Value or an Ending Annual Value is required
to be calculated is referred to herein as a "Calculation Day". A "NYSE Business
Day" is a day on which The New York Stock Exchange is open for trading. All
determinations made by the Calculation Agent shall be at the sole discretion of
the Calculation Agent and, in the absence of manifest error, shall be conclusive
for all purposes and binding on the Company and beneficial owners of the Notes.
All percentages resulting from any calculation on the Notes will be rounded to
the nearest one hundred-thousandth of a percentage point, with five one-
millionths of a percentage point rounded upwards (e.g., 9.876545% (or .09876545)
would be rounded to 9.87655% (or .0987655)), and all dollar amounts used in or
resulting from such calculation will be rounded to the nearest cent (with one-
half cent being rounded upwards).

  "Market Disruption Event" means either of the following events, as determined
by the Calculation Agent:

     (i) the suspension or material limitation (limitations pursuant to New York
  Stock Exchange Rule 80A (or any applicable rule or regulation enacted or
  promulgated by the New York Stock Exchange, any other self regulatory
  organization or the Securities and Exchange Commission of similar scope as
  determined by the Calculation Agent) on trading during significant market
  fluctuations shall be considered "material" for purposes of this definition),
  in each case, for more than two hours of trading in 80 or more of the
  securities included in the S&P MidCap 400 Index, or

     (ii) the suspension or material limitation, in each case for more than two
  hours of trading (whether by reason of movements in price exceeding levels
  permitted by the relevant exchange or otherwise), in (A) futures contracts
  related to the S&P MidCap 400 Index which are traded on the Chicago Mercantile
  Exchange or (B) option contracts related to the S&P MidCap 400 Index which are
  traded on the American Stock Exchange.

  For the purposes of this definition, a limitation on the hours in a trading
day and/or number of days of trading will not constitute a Market Disruption
Event if it results from an announced change in the regular business hours of
the relevant exchange.

INTEREST PAYMENT DATES

  The Company will make semiannual interest payments on the Notes on June 30 and
December 31 of each year ("June Payment Dates" and "December Payment Dates",
respectively), except as provided below, to the persons in whose names the Notes
are registered on the next preceding June 29 or December 30. For each Note, the
Company will pay half of the Minimum Annual Payment for each calendar year on
the June Payment Date, and will pay the balance of the annual amount payable on
such Note for such year on the December Payment Date.

  Notwithstanding the foregoing, if it is known at least three Business Days
prior to December 31 that December 31 will not be a Business Day, the amount
payable by the Company with respect to a December Payment Date for Series A
Notes will be made on the Business Day immediately preceding such December 31 to
the persons in whose names the Notes are registered on the second Business Day
immediately preceding such December 31.

Value and Ending Annual Value applicable to such year determined by the
Calculation Agent as provided herein and the Minimum Annual Payment, Maximum
Annual Payment and Participation Rate.

  A potential investor should review the historical performance of the S&P
MidCap 400 Index.  The historical performance of the S&P MidCap 400 Index should
not be taken as an indication of future performance, and no assurance can be
given that the S&P MidCap 400 Index will increase sufficiently during any
calendar year to cause the beneficial owners of the Notes to receive an amount
in excess of the Minimum Annual Payment during any such calendar year.

UNAVAILABILITY OF THE S&P MIDCAP 400 INDEX

  If S&P discontinues publication of the S&P MidCap 400 Index and S&P or another
entity publishes a successor or substitute index that the Calculation Agent
determines, in its sole discretion, to be comparable to the S&P MidCap 400 Index
(any such index being referred to hereinafter as a "Successor Index"), then,
upon the Calculation Agent's notification of such determination to the Trustee
and the Company, the Calculation Agent will substitute the Successor Index as
calculated by S&P or such other entity for the S&P MidCap 400 Index and
calculate the Starting Annual Value and/or the Ending Annual Value as described
above. Upon any selection by the Calculation Agent of a Successor Index, the
Company shall cause notice thereof to be published in The Wall Street Journal
(or another newspaper of general circulation) within three Business Days of such
selection.

  If the S&P MidCap 400 Index is unavailable or S&P discontinues publication of
the S&P MidCap 400 Index and a Successor Index is not selected by the
Calculation Agent or is no longer published on any of the Calculation Days, the
value to be substituted for the S&P MidCap 400 Index for any such Calculation
Day used to calculate the Starting Annual Value or Ending Annual Value, as the
case may be, will be calculated as described below.

                                       8
<PAGE>
 
  If a Successor Index is selected or the Calculation Agent calculates a value
as a substitute for the S&P MidCap 400 Index as described below, such Successor
Index or value shall be substituted for the S&P MidCap 400 Index for all
purposes.

  If at any time the method of calculating the S&P MidCap 400 Index, or the
value thereof, is changed in a material respect, or if the S&P MidCap 400 Index
is in any other way modified so that such Index does not, in the opinion of the
Calculation Agent, fairly represent the value of the S&P MidCap 400 Index had
such changes or modifications not been made, then, from and after such time, the
Calculation Agent shall, at the close of business in New York, New York, on each
Calculation Date, make such adjustments as, in the good faith judgment of the
Calculation Agent, may be necessary in order to arrive at a calculation of a
value of a stock index comparable to the S&P MidCap 400 Index as if such changes
or modifications had not been made, and calculate such closing value with
reference to the S&P MidCap 400 Index, as adjusted. Accordingly, if the method
of calculating the S&P MidCap 400 Index is modified so that the value of such
Index is a fraction or a multiple of what it would have been if it had not been
modified (e.g., due to a split in the Index), then the Calculation Agent shall
adjust such Index in order to arrive at a value of the S&P MidCap 400 Index as
if it had not been modified (e.g., as if such split had not occurred).

  If the S&P MidCap 400 Index is unavailable or the publication of the S&P
MidCap 400 Index is discontinued and S&P or another entity does not publish a
Successor Index on any of the Calculation Days, the value to be substituted for
the S&P MidCap 400 Index for any such Calculation Day will be the value computed
by the Calculation Agent for each such Calculation Day in accordance with the
following procedures:

     (1) identifying the component stocks of the S&P MidCap 400 Index or any
  Successor Index as of the last date on which either of such indices was
  calculated by S&P or another entity and published by S&P or such other entity
  (each such component stock is a "Last Component Stock");

     (2) for each Last Component Stock, calculating as of each such NYSE
  Business Day the product of the market price per share and the number of the
  then outstanding shares (such product referred to as the "Market Value" of
  such stock), by reference to (a) the closing market price per share of such
  Last Component Stock as quoted by the New York Stock Exchange or the American
  Stock Exchange or any other registered national securities exchange that is
  the primary market for such Last Component Stock, or if no such quotation is
  available, then the closing market price as quoted by any other registered
  national securities exchange or the National Association of Securities Dealers
  Automated Quotation National Market System ("NASDAQ"), or if no such price is
  quoted, then the market price from the best available source as determined by
  the Calculation Agent (collectively, the "Exchanges") and (b) the most recent
  publicly available statement of the number of outstanding shares of such Last
  Component Stock;

     (3) aggregating the Market Values obtained in clause (2) for all Last
  Component Stocks;

     (4) ascertaining the Base Value (as defined below under "The Standard &
  Poor's MidCap 400 Index--Computation of the S&P MidCap 400 Index") in effect
  as of the last day on which either the S&P MidCap 400 Index or any Successor
  Index was published by S&P or another entity, adjusted as described below;

     (5) dividing the aggregate Market Value of all Last Component Stocks by the
  Base Value (adjusted as aforesaid);

     (6) multiplying the resulting quotient (expressed in decimals) by 100.


  If any Last Component Stock is no longer publicly traded on any registered
national securities exchange or in the over-the-counter market, the last
available market price per share for such Last Component Stock as quoted by any
registered national securities exchange or in the over-the-counter market, and
the number of outstanding shares

                                       9
<PAGE>
 
thereof at such time, will be used in computing the last available Market Value
of such Last Component Stock. Such Market Value will be used in all computations
of the S&P MidCap 400 Index thereafter.

  If a company that has issued a Last Component Stock and another company that
has issued a Last Component Stock are consolidated to form a new company, the
common stock of such new company will be considered a Last Component Stock and
the common stocks of the constituent companies will no longer be considered Last
Component Stocks. If any company that has issued a Last Component Stock merges
with, or acquires, a company that has not issued a Last Component Stock, the
common stock of the surviving corporation will, upon the effectiveness of such
merger or acquisition, be considered a Last Component Stock. In each such case,
the Base Value will be adjusted so that the Base Value immediately after such
consolidation, merger or acquisition will equal (a) the Base Value immediately
prior to such event, multiplied by (b) the quotient of the aggregate Market
Value of all Last Component Stocks immediately after such event, divided by the
aggregate Market Value for all Last Component Stocks immediately prior to such
event.

  If a company that has issued a Last Component Stock issues a stock dividend,
declares a stock split or issues new shares pursuant to the acquisition of
another company, then, in each case, the Base Value will be adjusted (in
accordance with the formula described below) so that the Base Value immediately
after the time the particular Last Component Stock commences trading ex-
dividend, the effectiveness of the stock split or the time new shares of such
Last Component Stock commence trading equals (a) the Base Value immediately
prior to such event, multiplied by (b) the quotient of the aggregate Market
Value for all Last Component Stocks immediately after such event, divided by the
aggregate Market Value of all Last Component Stocks immediately prior to such
event. The Base Value used by the Calculation Agent to calculate the value
described above will not necessarily be adjusted in all cases in which S&P, in
its discretion, might adjust the Base Value (as described below under "The
Standard & Poor's MidCap 400 Index--Computation of the S&P MidCap 400 Index").

  If S&P discontinues publication of the S&P MidCap 400 Index prior to the
period during which the amount payable with respect to any year is to be
determined and the Calculation Agent determines that no Successor Index is
available at such time, then on each NYSE Business Day until the earlier to
occur of (i) the determination of the amount payable with respect to such year
or (ii) a determination by the Calculation Agent that a Successor Index is
available, the Calculation Agent shall determine the value that would be used in
computing the amount payable with respect to such year by reference to the
method set forth in clauses (1) through (6) in the fourth preceding paragraph
above as if such day were a Calculation Day. The Calculation Agent will cause
notice of each such value to be published not less often than once each month in
the Wall Street Journal (or another newspaper of general circulation), and
arrange for information with respect to such values to be made available by
telephone. Notwithstanding these alternative arrangements, discontinuance of the
publication of the S&P MidCap 400 Index may adversely affect trading in the
Notes.

EVENTS OF DEFAULT AND ACCELERATION

  In case an Event of Default with respect to any Notes shall have occurred and
be continuing, the amount payable to a beneficial owner of a Note upon any
acceleration permitted by the Notes, will equal: (i) the principal amount
thereof, plus (ii) an additional amount, if any, of interest calculated as
though the date of early repayment were a December Payment Date and prorated
through such date of early repayment based on the ratio of the number of days
from and including the date the Starting Annual Value applicable to such year is
determined to but excluding the date of early repayment, computed on the basis
of a year consisting of 360 days of twelve 30-day months, divided by 360. If a
bankruptcy proceeding is commenced in respect of the Company, the claim of the
beneficial owner of a Note may be limited, under Section 502(b)(2) of Title 11
of the United States Code, to the principal amount of the Note plus an
additional amount, if any, of contingent interest calculated as though the date
of the commencement of the proceeding were the maturity date of the Notes.

SECURITIES DEPOSITORY

  The Notes are represented by one fully registered global security (the "Global
Security"). Such Global Security has been deposited with, or on behalf of, The
Depository Trust Company, as Securities Depository (the "Securities
Depository"), registered in the name of the Securities Depository or a nominee
thereof. Unless and until it is exchanged in whole or in part for Securities in
definitive form, the Global Security may be transferred except as a whole by the
Securities Depository to a nominee of such Securities Depository or by a nominee
of such Securities Depository to such Securities Depository or another nominee
of such Securities Depository or by such Securities Depository or any such
nominee to a successor of such Securities Depository or a nominee of such
successor.

  The Securities Depository has advised the Company as follows: The Securities
Depository is a limited-purpose trust company organized under the Banking Law of
the State of New York, a member of the Federal Reserve System, a "clearing
corporation" within the meaning of the New York Uniform Commercial Code, and a
"clearing agency" registered pursuant to the provisions of Section 17A of the
Exchange Act.  The Securities Depository was created to hold securities of its
participants ("Participants") and to facilitate the clearance and settlement of
securities transactions among its Participants in such securities through
electronic book-entry changes in accounts of the Participants, thereby
eliminating the need for physical movement of securities certificates. The
Securities Depository's Participants include securities brokers and dealers,
banks, trust companies, clearing corporations, and certain other organizations.
The Securities Depository is owned by a number of Participants and by the New
York Stock Exchange, Inc., the American Stock Exchange, Inc. and the National
Association of Securities Dealers, Inc.  Access to the Securities Depository
book-entry system is also available to others, such as banks, brokers, dealers
and trust companies that clear through or maintain a custodial relationship with
a Participant, either directly or indirectly ("Indirect Participants").

  Purchases of Notes must be made by or through Participants, which will receive
a credit on the records of the Securities Depository. The ownership interest of
each actual purchaser of each Note ("Beneficial Owner") is in turn to be
recorded on the Participants' or Indirect Participants' records. Beneficial
Owners will not receive written confirmation from the Securities Depository of
their purchase, but Beneficial Owners are expected to receive written
confirmations providing details of the transaction, as well as periodic
statements of their holdings, from the Participant or Indirect Participant
through which the Beneficial Owner entered into the transaction. Ownership of
beneficial interests in such Global Security will be shown on, and the transfer
of such ownership interests will be effected only through, records maintained by
the Securities Depository (with respect to interests of Participants) and on the
records of Participants (with respect to interests of persons held through
Participants). The laws of some states may require that certain purchasers of
securities take physical delivery of such securities in definitive form. Such
limits and such laws may impair the ability to own, transfer or pledge
beneficial interests in Global Securities.

  So long as the Securities Depository, or its nominee, is the registered owner
of the Global Security, the Securities Depository or its nominee, as the case
may be, will be considered the sole owner or Holder of the Notes represented by
such Global Security for all purposes under the Senior Indenture. Except as
provided below, Beneficial Owners in the Global Security will not be entitled to
have the Notes represented by such Global Security registered in their names,
will not receive or be entitled to receive physical delivery of the Notes in
definitive registered form and will not be considered the owners or Holders
thereof under the Senior Indenture. Accordingly, each Person owning a beneficial
interest in the Global Security must rely on the procedures of the Securities
Depository and, if such Person is not a Participant, on the procedures of the
Participant through which such Person owns its interest, to exercise any rights
of a Holder under the Senior Indenture. The Company understands that under
existing industry practices, in the event that the Company requests any action
of Holders or that an owner of a beneficial interest in the Global Security
desires to give or take any action which a Holder is entitled to give or take
under the Senior Indenture, the Securities Depository would authorize the
Participants holding the relevant beneficial interests to give or take such
action, and such Participants would authorize Beneficial Owners owning through
such Participants to give or take such action or would otherwise act upon the
instructions of beneficial owners. Conveyance of notices and other
communications by the Securities Depository to Participants, by Participants to
Indirect Participants, and by

                                       11
<PAGE>
 
Participants and Indirect Participants to Beneficial Owners will be governed by
arrangements among them, subject to any statutory or regulatory requirements as
may be in effect from time to time.

  Payment of the principal of, and amounts payable on any June Payment Date or
December Payment Date with respect to Notes registered in the name of the
Securities Depository or its nominee, will be made to the Securities Depository
or its nominee, as the case may be, as the Holder of the Global Security
representing such Notes. None of the Company, the Trustee or any other agent of
the Company or agent of the Trustee will have any responsibility or liability
for any aspect of the records relating to or payments made on account of
beneficial ownership interests or for supervising or reviewing any records
relative to such beneficial ownership interests. The Company expects that the
Securities Depository, upon receipt of any payment of principal or amounts
payable on any June Payment Date or December Payment Date in respect of the
Global Security, will credit the accounts of the Participants with payment in
amounts proportionate to their respective holdings in principal amount of
beneficial interest in such Global Security as shown on the records of the
Securities Depository. The Company also expects that payments by Participants to
Beneficial Owners will be governed by standing customer instructions and
customary practices, as is now the case with securities held for the accounts of
customers in bearer form or registered in "street name", and will be the
responsibility of such Participants.

  If (x) the Securities Depository is at any time unwilling or unable to
continue as Securities Depository and a successor depository is not appointed by
the Company within 60 days, (y) the Company executes and delivers to the Trustee
a Company Order to the effect that the Global Security shall be exchangeable or
(z) an Event of Default has occurred and is continuing with respect to the
Notes, the Global Security will be exchangeable for Notes in definitive form of
like tenor and of an equal aggregate principal amount, in denominations of
$1,000 and integral multiples thereof. Such definitive Notes shall be registered
in such name or names as the Securities Depository shall instruct the Trustee.
It is expected that such instructions may be based upon directions received by
the Securities Depository from Participants with respect to ownership of
beneficial interests in such Global Security.


                     THE STANDARD & POOR'S MIDCAP 400 INDEX

  All disclosure contained in this Prospectus regarding the S&P MidCap 400
Index, including, without limitation, its make-up, method of calculation and
changes in its components, is derived from publicly available information
prepared by S&P as of April 16, 1993. Neither the Company nor MLPF&S take any
responsibility for such information.

GENERAL

  The S&P MidCap 400 Index is published by S&P and is intended to provide an
indication of the pattern of price movements of common stocks of corporations
having mid-market capitalization. The calculation of the value of the S&P MidCap
400 Index (discussed below in further detail) is based on the relative value of
the aggregate Market Value (as defined above) of the common stocks of 400
companies as of a particular time as compared to the aggregate average Market
Value of the common stocks of 400 substantially similar companies on December
31, 1990. As of April 16, 1993, 263 (66%) of the companies included in the S&P
MidCap 400 Index were listed on the New York Stock Exchange, 125 (31%) of the
companies were traded in the over-the-counter market and 12 (3%) of the
companies were listed on the American Stock Exchange. As of February 3, 1993,
the aggregate Market Value of the 400 companies included in the S&P MidCap 400
Index represented approximately 15% of the aggregate Market Value of United
States domestic companies. The 400 companies are not the largest companies
listed on The New York Stock Exchange (the companies included in the Standard &
Poor's 500 Composite Stock Price Index, which had a median market capitalization
of $3.1 billion at April 16, 1993, are generally larger than those included in
the S&P MidCap 400 Index, which had a median market capitalization of $846.8
million at April 16, 1993). S&P chooses companies for inclusion in the S&P
MidCap 400 Index with the aim of achieving (for companies of mid-market
capitalization) a distribution by broad industry groupings that approximates the
distribution of these groupings in the common stock population of The New York
Stock Exchange, which S&P uses as an assumed model

                                       12
<PAGE>
 
for the composition of the total market with respect to such mid-market
corporations. Relevant criteria employed by S&P in selecting companies for the
S&P MidCap 400 Index include the viability of the particular company, the extent
to which that company represents the industry group to which it is assigned, the
extent to which the market price of that company's common stock is generally
responsive to changes in the affairs of the respective industry and the Market
Value and trading activity of the common stock of that company.


COMPUTATION OF THE S&P MIDCAP 400 INDEX

  As of April 16, 1993, S&P computed the S&P MidCap 400 Index as of a particular
time as follows:

     (1) the Market Value of each component stock is determined as of such time;

     (2) the Market Values of all component stocks as of such time (as
  determined under clause (1) above) are aggregated;

     (3) the Market Values as of December 31, 1990 (the "Base Period") of the
  common stock of each company in a group of 400 substantially similar companies
  is determined;

     (4) the Market Values of all such common stocks as of the Base Period (as
  determined under clause (3) above) are aggregated (such aggregate amount being
  referred to as the "Base Value");

     (5) the aggregate Market Value of all component stocks as of such time (as
  determined under clause (2) above) is divided by the Base Value; and

     (6) the resulting quotient (expressed in decimals) is multiplied by 100.

  While S&P currently employs the above methodology to calculate the S&P MidCap
400 Index, no assurance can be given that S&P will not modify or change such
methodology in a manner that may affect the amounts payable on any December
Payment Date to beneficial owners of the Notes.

  S&P adjusts the foregoing formula to negate the effect of changes in the
Market Value of a component stock that are determined by S&P to be arbitrary or
not due to true market fluctuations. Such changes may result from such causes as
the issuance of stock dividends, the granting to shareholders of rights to
purchase additional shares of such stock, the purchase of additional shares of
stock by employees pursuant to employee benefit plans, certain consolidations
and acquisitions, the granting to shareholders of rights to purchase other
securities of the company, the substitution by S&P of particular component
stocks in the S&P MidCap 400 Index and other reasons. In all such cases, S&P
first recalculates the aggregate Market Value of all component stocks (after
taking account of the new market price per share of the particular component
stock or the new number of outstanding shares thereof or both, as the case may
be) and then determines the New Base Value in accordance with the following
formula:

                                New Market Value
              Old Base Value x ________________  = New Base Value
                                Old Market Value

The result is that the Base Value is adjusted in proportion to any change in the
aggregate Market Value of all component stocks resulting from the causes
referred to above to the extent necessary to negate the effects of such causes
upon the S&P MidCap 400 Index.

                                       13

  A potential investor should review the historical performance of the S&P
MidCap 400 Index.  The historical performance of the S&P MidCap 400 Index should
not be taken as an indication of future performance, and no assurance can be
given that the S&P MidCap 400 Index will increase sufficiently to cause the
beneficial owners of the Notes to receive an amount in excess of the principal
amount at the maturity of the Notes.

LICENSE AGREEMENT

  S&P and Merrill Lynch Capital Services, Inc. have entered into a non-exclusive
license agreement providing for the license to Merrill Lynch Capital Services,
Inc., in exchange for a fee, of the right to use indices owned and published by
S&P in connection with certain securities, including the Notes, and the Company
is an authorized sublicensee thereof.

  The license agreement between S&P and Merrill Lynch Capital Services, Inc.
provides that the following language must be stated in this Prospectus:

     "The Notes are not sponsored, endorsed, sold or promoted by S&P. S&P makes
  no representation or warranty, express or implied, to the Holders of the Notes
  or any member of the public regarding the advisability of investing in
  securities generally or in the Notes particularly or the ability of the S&P
  MidCap 400 Index to track general stock market performance. S&P's only
  relationship to Merrill Lynch Capital Services, Inc. and the Company (other
  than transactions entered into in the ordinary course of business) is the
  licensing of certain service marks and trade names of S&P and of the S&P
  MidCap 400 Index which is determined, composed and calculated by S&P without
  regard to the Company or the Notes. S&P has no obligation to take the needs of

                                  OTHER TERMS

GENERAL

  The Note were issued as a series of Senior Debt Securities under the Indenture
(the "Senior Indenture"), dated as of April 1, 1983, as amended and restated,
between the Company and The Chase Manhattan Bank, formerly known as Chemical
Bank (successor by merger to Manufacturers Hanover Trust Company), as trustee
(the "Trustee"). A copy of the Senior Indenture is filed as an exhibit to the
registration statements relating to the Notes.  The following summaries of
certain provisions of the Senior Indenture do not purport to be complete and are
subject to, and qualified in their entirety by reference to, all provisions of
the Senior Indenture, including the definition therein of certain terms.

  The Senior Indenture provides that series of Senior Debt Securities may from
time to time be issued thereunder, without limitation as to aggregate principal
amount, in one or more series and upon such terms as the Company may establish
pursuant to the provisions thereof.

  The Senior Indenture provides that the Senior Indenture and the Notes are
governed by and construed in accordance with the laws of the State of New York.

  The Senior Indenture provides that the Company may issue Senior Debt
Securities with terms different from those of Senior Debt Securities previously
issued, and "reopen" a previously issued series of Senior Debt Securities and
issue additional Senior Debt Securities of such series.

                                       14
<PAGE>
 
  The Senior Debt Securities are unsecured and rank pari passu with all other
unsecured and unsubordinated indebtedness of the Company.  However, since the
Company is a holding company, the right of the Company, and hence the right of
creditors of the Company (including the Holders of Senior Debt Securities), to
participate in any distribution of the assets of any subsidiary upon its
liquidation or reorganization or otherwise is necessarily subject to the prior
claims of creditors of the subsidiary, except to the extent that claims of the
Company itself as a creditor of the subsidiary may be recognized.  In addition,
dividends, loans and advances from certain subsidiaries, including MLPF&S, to
the Company are restricted by net capital requirements under the Securities
Exchange Act of 1934, as amended, and under rules of certain exchanges and other
regulatory bodies.

LIMITATIONS UPON LIENS

  The Company may not, and may not permit any Subsidiary to, create, assume,
incur or permit to exist any indebtedness for borrowed money secured by a
pledge, lien or other encumbrance (except for certain liens specifically
permitted by the Senior Indenture) on the Voting Stock owned directly or
indirectly by the Company of any Subsidiary (other than a Subsidiary which, at
the time of the incurrence of such secured indebtedness, has a net worth of less
than $3,000,000) without making effective provision whereby the Outstanding
Senior Debt Securities will be secured equally and ratably with such secured
indebtedness.

LIMITATION ON DISPOSITION OF VOTING STOCK OF, AND MERGER AND SALE OF ASSETS BY,
MLPF&S

  The Indenture provides that the Company may not sell, transfer or otherwise
dispose of any Voting Stock of MLPF&S or permit MLPF&S to issue, sell or
otherwise dispose of any of its Voting Stock, unless, after giving effect to any
such transaction, MLPF&S remains a Controlled Subsidiary (defined in the Senior
Indenture to mean a corporation more than 80% of the outstanding shares of
Voting Stock of which are owned directly or indirectly by the Company).  In
addition, the Company may not permit MLPF&S to (i) merge or consolidate, unless
the surviving company is a Controlled Subsidiary or (ii) convey or transfer its
properties and assets substantially as an entirety, except to one or more
Controlled Subsidiaries.

MERGER AND CONSOLIDATION

  The Indenture provides that the Company may consolidate or merge with or into
any other corporation, and the Company may sell, lease or convey all or
substantially all of its assets to any corporation, provided that (i) the
corporation (if other than the Company) formed by or resulting from any such
consolidation or merger or which shall have received such assets shall be a
corporation organized and existing under the laws of the United States of
America or a state thereof and shall assume payment of the principal of (and
premium, if any) and interest on the Senior Debt Securities and the performance
and observance of all of the covenants and conditions of the Senior Indenture to
be performed or observed by the Company, and (ii) the Company or such successor
corporation, as the case may be, shall not immediately thereafter be in default
under the Senior Indenture.

MODIFICATION AND WAIVER

  Modification and amendment of the Indenture may be effected by the Company and
the Trustee with the consent of the Holders of 66 2/3% in principal amount of
the Outstanding Senior Debt Securities of each series issued pursuant to such
indenture and affected thereby, provided that no such modification or amendment
may, without the consent of the Holder of each Outstanding Senior Debt Security
affected thereby, (a) change the Stated Maturity of the principal of, or any
installment of interest or Additional Amounts payable on, any Senior Debt
Security or any premium payable on the redemption thereof, or change the
Redemption Price; (b) reduce the principal amount of, or the interest or
Additional Amounts payable on, any Senior Debt Security or reduce the amount of
principal which could be declared due and payable prior to the Stated Maturity;
(c) change place or currency of any payment of principal or any premium,
interest or Additional Amounts payable on any Senior Debt Security; (d) impair
the right to institute suit for the enforcement of any payment on or with
respect to any Senior Debt Security; (e) reduce the percentage in principal
amount of the Outstanding Senior Debt Securities of any series, the consent of
whose Holders

                                       15
<PAGE>
 
is required to modify or amend the Indenture; or (f) modify the foregoing
requirements or reduce the percentage of Outstanding Senior Debt Securities
necessary to waive any past default to less than a majority.  No modification or
amendment of the Subordinated Indenture or any Subsequent Indenture for
Subordinated Debt Securities may adversely affect the rights of any holder of
Senior Indebtedness without the consent of such Holder.  Except with respect to
certain fundamental provisions, the Holders of at least a majority in principal
amount of Outstanding Senior Debt Securities of any series may, with respect to
such series, waive past defaults under the Indenture and waive compliance by the
Company with certain provisions thereof.

EVENTS OF DEFAULT

  Under the Senior Indenture, the following will be Events of Default with
respect to Senior Debt Securities of any series: (a) default in the payment of
any interest or Additional Amounts payable on any Senior Debt Security of that
series when due, continued for 30 days; (b) default in the payment of any
principal or premium, if any, on any Senior Debt Security of that series when
due; (c) default in the deposit of any sinking fund payment, when due, in
respect of any Senior Debt Security of that series; (d) default in the
performance of any other covenant of the Company contained in the Indenture for
the benefit of such series or in the Senior Debt Securities of such series,
continued for 60 days after written notice as provided in the Senior Indenture;
(e) certain events in bankruptcy, insolvency or reorganization; and (f) any
other Event of Default provided with respect to Senior Debt Securities of that
series.  The Trustee or the Holders of 25% in principal amount of the
Outstanding Senior Debt Securities of that series may declare the principal
amount (or such lesser amount as may be provided for in the Senior Debt
Securities of that series) of all Outstanding Senior Debt Securities of that
series and the interest due thereon and Additional Amounts payable in respect
thereof, if any to be due and payable immediately if an Event of Default with
respect to Senior Debt Securities of such series shall occur and be continuing
at the time of such declaration.  At any time after a declaration of
acceleration has been made with respect to Senior Debt Securities of any series
but before a judgment or decree for payment of money due has been obtained by
the Trustee, the Holders of a majority in principal amount of the Outstanding
Senior Debt Securities of that series may rescind any declaration of
acceleration and its consequences, if all payments due (other than those due as
a result of acceleration) have been made and all Events of Default have been
remedied or waived.  Any Event of Default with respect to Senior Debt Securities
of any series may be waived by the Holders of a majority in principal amount of
all Outstanding Senior Debt Securities of that series, except in a case of
failure to pay principal or premium, if any, or interest or Additional Amounts
payable on any Senior Debt Security of that series for which payment had not
been subsequently made or in respect of a covenant or provision which cannot be
modified or amended without the consent of the Holder of each Outstanding Senior
Debt Security of such series affected.

  The Holders of a majority in principal amount of the Outstanding Senior Debt
Securities of a series may 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 Senior Debt Securities of such
series, provided that such direction shall not be in conflict with any rule of
law or the Senior Indenture.  Before proceeding to exercise any right or power
under the Senior Indenture at the direction of such Holders, the Trustee shall
be entitled to receive from such Holders reasonable security or indemnity
against the costs, expenses and liabilities which might be incurred by it in
complying with any such direction.

  The Company is required to furnish to the Trustee annually a statement as to
the fulfillment by the Company of all of its obligations under the Senior
Indenture.

                    MERRILL LYNCH & CO., INC.  JAPAN INDEX/SM/
 EQUITY PARTICIPATION SECURITIES WITH MINIMUM RETURN PROTECTION DUE JANUARY 31,
                                      2000

  On January 27, 1994, Merrill Lynch & Co., Inc. (the "Company") issued
$115,000,000 aggregate principal amount of Japan Index/SM/ Equity Participation
Securities with Minimum Return Protection due January 31, 2000 (the "Securities"
or the "Notes") in denominations of $1,000 and integral multiples thereof.  As
of the date of this Prospectus, $60,000,000 aggregate principal amount of the
Securities remain outstanding.  The Securities will mature on January 31, 2000.
At maturity, a beneficial owner of a Security will be entitled to receive, with
respect to each Security, the principal amount thereof plus an interest payment
(the "Supplemental Redemption Amount") based on the percentage increase, if any,
in the Index (as hereinafter defined). The Securities were issued as a series of
Senior Debt Securities under the Senior Indenture described herein. The
Securities are not redeemable or callable by the Company prior to maturity.
While at maturity a beneficial owner of a Security will receive the principal
amount of such Security plus the Supplemental Redemption Amount, there will be
no payment of interest, periodic or otherwise.

  The Supplemental Redemption Amount payable with respect to a Security at
maturity will equal the product of (A) the principal amount of the applicable
Security, (B) the percentage change from 195.46, the closing value of the Index
on January 20, 1994 as compared to the Final Average Value (as hereinafter
defined), and (C) 115% (the "Participation Rate"). In no event, however, will
the Supplemental Redemption Amount be less than $150 per $1,000 principal amount
of the Securities (the "Minimum Supplemental Redemption Amount"), representing a
minimum annualized rate of return of 2.33%. The calculation of the Final Average
Value, as more fully described herein, will equal the arithmetic average of the
closing values of the Index on certain days during January of 1998, 1999 and
2000. Although the Index will initially be the Japan Index (as defined herein),
under certain circumstances described herein, a New Japan Index (as defined
herein) may be substituted for the Japan Index. The Japan Index (or, if such
substitution shall occur, the New Japan Index) is referred to herein as the
"Index".

  For information as to the calculation of the Supplemental Redemption Amount
which will be paid at maturity and the calculation and the composition of the
Index, see "Description of Securities" and "The Index", respectively, in this
Prospectus. FOR OTHER INFORMATION THAT SHOULD BE CONSIDERED BY PROSPECTIVE
INVESTORS, SEE "RISK FACTORS" BEGINNING ON PAGE 3 OF IN THIS PROSPECTUS.

  Ownership of the Securities is maintained in book-entry form by or through the
Depository (as hereinafter defined). Beneficial owners of the Securities do not
have the right to receive physical certificates evidencing their ownership
except under the limited circumstances described herein.

  The Securities have been listed on the American Stock Exchange under the
symbol "MJP.A".

  For the purpose of calculating the ratio of earnings to fixed charges,

and fixed charges.  "Fixed charges" consists of interest costs, amortization of
debt expense, preferred stock dividend requirements of majority-owned
subsidiaries, and that portion of rentals estimated to be representative of the
interest factor.


                                  RISK FACTORS

PAYMENT AT MATURITY

  Investors should be aware that if the Final Average Value of the Index does
not exceed the Initial Value by more than approximately 13.04%, beneficial
owners of the Securities will receive only the principal amount thereof and the
Minimum Supplemental Redemption Amount. A beneficial owner of the Securities may
receive a Supplemental Redemption Amount equal only to the Minimum Supplemental
Redemption Amount at maturity, and

                                       3
<PAGE>
 
such Minimum Supplemental Redemption Amount is below what the Company would pay
as interest as of the date of issuance if the Company issued non-callable senior
debt securities with a similar maturity as that of the Securities. The return of
principal of the Securities at maturity and the payment of the Minimum
Supplemental Redemption Amount are not expected to reflect the full opportunity
costs implied by inflation or other factors relating to the time value of money.

  The Index does not reflect the payment of dividends on the stocks underlying
it and therefore, in addition to the considerations regarding averaging
discussed below, the yield based on the Index to the maturity of the Securities
will not produce the same yield as if such underlying stocks were purchased and
held for a similar period. Because the Final Average Value will be based upon
average values of the Index during specified periods in three successive years,
a significant increase in the Index as measured by the average values during the
specified period in the final year, or in either earlier year, may be
substantially or entirely offset by the average values of the Index during the
specified periods in the other two years.

  The Index used to calculate the Supplemental Redemption Amount will initially
be the Japan Index, which is currently calculated and published by the American
Stock Exchange. Upon the occurrence of certain events described under
"Description of Securities--Substitution of the Index", a New Japan Index (which
will also relate to the trading of equity securities in Japan) will be
substituted for the Japan Index as the basis of the calculation of the
Supplemental Redemption Amount. The required characteristics of such New Japan
Index are described herein; however, the New Japan Index does not currently
exist, and such New Japan Index may be calculated and published by a United
States stock exchange other than the American Stock Exchange. In the event that
a New Japan Index is substituted for the Japan Index, no assurance can be given
as to whether the Supplemental Redemption Amount calculated on the basis of such
New Japan Index will be more than or less than or equal to the Supplemental
Redemption Amount which would have been payable had such substitution not
occurred.

  The Senior Indenture provides that the Senior Indenture and the Securities
will be governed by and construed in accordance with the laws of New York. Under
present New York law the maximum rate of interest is 25% per annum on a simple
interest basis. This limit may not apply to Securities in which $2,500,000 or
more has been invested. While the Company believes that New York law would be
given effect by a state or Federal court sitting outside of New York, state laws
frequently regulate the amount of interest that may be charged to and paid by a
borrower (including, in some cases, corporate borrowers). The Company has
covenanted for the benefit of the Holders of the Securities, to the extent
permitted by law, not to claim voluntarily the benefits of any laws concerning
usurious rates of interest against a Holder of the Securities.

TRADING

  The Securities are listed on the American Stock Exchange. It is expected that
the secondary market for the Securities will be affected by the creditworthiness
of the Company and by a number of other factors. Because the Final Average Value
is an average of the three Calculation Values as described below, the price at
which a beneficial owner of a Security will be able to sell such Security in the
secondary market may be at a discount if the first or second such Calculation
Value is below the Initial Value.

  The trading value of the Securities is expected to depend primarily on the
extent of the appreciation, if any, of the Index over the Initial Value. If,
however, Securities are sold prior to the maturity date at a time when the Index
exceeds the Initial Value, the sale price may be at a discount from the amount
expected to be payable to the beneficial owner if such excess of the Index over
the Initial Value were to prevail until maturity of the Securities because of
the possible fluctuation of the Index between the time of such sale and the
maturity date and the effect of the value of the Index on prior days used to
calculate the Final Average Value, if any. Furthermore, the price at which a
beneficial owner will be able to sell Securities prior to maturity may be at a
discount, which could be substantial, from the principal amount thereof if, at
such time, the Index is below, equal to or not sufficiently above the Initial
Value and/or if the value of the Index on prior days used to calculate the Final
Average Value, if any,

                                       4
<PAGE>
 
was below, equal to or not sufficiently above the Initial Value. A discount
could also result from rising interest rates in the U.S.

  The trading values of the Securities may be affected by a number of
interrelated factors, including the creditworthiness of the Company and those
factors listed below. The relationship among these factors is complex, including
how these factors affect the relative value of the principal amount of the
Securities to be repaid at maturity and the value of the Supplemental Redemption
Amount. Accordingly, investors should be aware that factors other than the level
of the Index are likely to affect the Securities' trading value. The expected
theoretical effect on the trading value of the Securities of each of the factors
listed below, assuming in each case that all other factors are held constant, is
as follows:

     Interest Rates. In general, if U.S. interest rates increase, the value of
  the Securities is expected to decrease. If U.S. interest rates decrease, the
  value of the Securities is expected to increase. In general, if Japanese
  interest rates increase, the value of the Securities is expected to increase.
  If Japanese interest rates decrease, the value of the Securities is expected
  to decrease. Interest rates may also affect the Japanese economy, and, in
  turn, the value of the Index. Rising interest rates may lower the value of the
  Index and, thus, the Securities. Falling interest rates may increase the value
  of the Index and, thus, may increase the value of the Securities.

     Volatility of the Index. If the volatility of the Index increases, the
  trading value of the Securities is expected to increase. If the volatility of
  the Index decreases, the trading value of the Securities is expected to
  decrease.

     Time Remaining to Maturity. The Securities may trade at a value above that
  which may be inferred from the level of interest rates and the Index. This
  difference will reflect a "time premium" due to expectations concerning the
  value of the Index during the period prior to maturity of the Securities. As
  the time remaining to maturity of the Securities decreases, however, this time
  premium is expected to decrease, thus decreasing the trading value of the
  Securities. In addition, the price at which a beneficial owner may be able to
  sell Securities prior to maturity may be at a discount, which may be
  substantial, from the minimum expected value at maturity if one or more
  Calculation Values, as defined below, were below, equal to or not sufficiently
  above the Initial Value.

     Dividend Rates in Japan. If dividend rates on the stocks comprising the
  Index increase, the value of the Securities is expected to decrease.
  Conversely, if dividend rates on the stocks comprising the Index decrease, the
  value of the Securities is expected to increase. However, in general, rising
  Japanese corporate dividend rates may increase the value of the Index and, in
  turn, increase the value of the Securities. Conversely, falling Japanese
  dividend rates may decrease the value of the Index and, in turn, decrease the
  value of the Securities.

  Although the stocks comprising the Japan Index are traded in Japanese yen and
the Securities are denominated in U.S. dollars, the Supplemental Redemption
Amount will not be adjusted for the currency exchange rate in effect at the
maturity of the Securities. The Supplemental Redemption Amount is based upon the
percentage increase in the Japan Index. The Japan Index is calculated using a
constant U.S.$/Japanese Yen exchange rate. The value of the Securities should
not, therefore, be directly affected by the currency exchange rate. For example,
if the Japan Index were to increase by 25% from the Initial Value to the Final
Average Value, a holder of the Securities would receive a Supplemental
Redemption Amount equal to $287.50 per $1,000 principal amount of Securities at
maturity regardless of the U.S.$/Japanese Yen exchange rate prevailing at
maturity. Changes in the exchange rate, however, may reflect changes in the
Japanese economy which, of course, would affect the value of the Index and the
Securities.

THE JAPANESE MARKET

  The underlying stocks that constitute the Japan Index have been issued by
Japanese companies. If a New Japan Index is substituted for the Japan Index,
such New Japan Index would also be based upon stocks issued by Japanese
companies. Investments in securities indexed to the value of Japanese equity
securities involve certain risks. The Japanese securities markets may be more
volatile than U.S. or other securities markets and may be affected by market
developments in different ways than U.S. or other securities markets. Direct or
indirect government intervention to stabilize the Japanese securities markets
and cross-shareholdings in Japanese companies on such markets may affect prices
and volume of trading on those markets. Also, there is generally less publicly
available information about Japanese companies than about those U.S. companies
that are subject to the reporting requirements of the Commission, and Japanese
companies are subject to accounting, auditing and financial reporting standards
and requirements that differ from those to which U.S. reporting companies are
subject.

  Securities prices in Japan are subject to political, economic, financial and
social factors that apply in Japan. These factors (including the possibility
that recent or future changes in the Japanese government's economic and fiscal
policies, the possible imposition of, or changes in, currency exchange laws or
other Japanese laws or restrictions applicable to Japanese companies or
investments in Japanese equity securities and the possibility of fluctuations in
the rate of exchange between currencies) could negatively affect the Japanese
securities markets. Moreover, the Japanese economy may differ favorably or
unfavorably from the U.S. economy in such respects as growth of gross national
product, rate of inflation, capital reinvestment, resources and self-
sufficiency.

OTHER CONSIDERATIONS

  It is suggested that prospective investors who consider purchasing the
Securities should reach an investment decision only after carefully considering
the suitability of the Securities in light of their particular circumstances.

  Investors should also consider the tax consequences of investing in the
Securities and should consult their tax advisors.


                           DESCRIPTION OF SECURITIES
GENERAL

  The Securities were issued as a series of Senior Debt Securities under the
Senior Indenture, dated as of April 1, 1983, as amended and restated, which is
more fully described below. The Securities will mature on January 31, 2000.

  While at maturity a beneficial owner of a Security will receive the principal
amount of such Security plus the Supplemental Redemption Amount, there will be
no payment of interest, periodic or otherwise. (See "Payment at Maturity",
below.)

  The Securities are not subject to redemption by the Company or at the option
of any beneficial owner prior to maturity. Upon the occurrence of an Event of
Default with respect to the Securities, beneficial owners of the Securities may
accelerate the maturity of the Securities, as described under "Description of
Securities--Events of Default and Acceleration" and "Other Terms--Events of
Default" in this Prospectus.

  The Securities were issued in denominations of $1,000 and integral multiples
thereof.

                                       6
<PAGE>
 
PAYMENT AT MATURITY

  At maturity, a beneficial owner of a Security will be entitled to receive the
principal amount thereof plus a Supplemental Redemption Amount, all as provided
below. If the Final Average Value of the Index does not exceed the Initial Value
by more than approximately 13.04% a beneficial owner of a Security will be
entitled to receive only the principal amount thereof and the Minimum
Supplemental Redemption Amount. Although the Index will initially be the Japan
Index, under certain circumstances described herein a New Japan Index (as
defined herein) may be substituted for the Japan Index. The Japan Index (or, if
such substitution shall occur, the New Japan Index) is referred to herein as the
"Index".

  At maturity, a beneficial owner of a Security will be entitled to receive,
with respect to each such Security, (i) the principal amount thereof, and (ii)
the Supplemental Redemption Amount equal in amount to:

                          Final Average Value-Initial Value 
  Principal Amount   x    ---------------------------------  x  115%
                                     Initial Value

provided, that the Supplemental Redemption Amount will not be less than the
Minimum Supplemental Redemption Amount of $150 per $1,000 principal amount of
Securities. The Initial Value equals 195.46, the closing value of the Japan
Index on January 20, 1994; provided, however, that a new Initial Value will be
calculated as described herein if a New Japan Index is substituted for the Japan
Index.

  The Final Average Value of the Index will be determined by State Street Bank
and Trust Company (the "Calculation Agent") and will equal the arithmetic
average (mean) of the Yearly Values, as defined below, for 1998, 1999 and 2000.
The Yearly Value for any year will be calculated during the Calculation Period
for such year which will be from and including January 22 in 1998, January 21 in
1999 and January 20 in 2000 to and including the fifth scheduled Business Day
after each such date. The Yearly Value for each year will equal the arithmetic
average (mean) of the closing values of the Index on the first Business Day in
the applicable Calculation Period (provided that a Market Disruption Event, as
defined below, shall not have occurred on such day) and on each succeeding
Business Day (provided that a Market Disruption Event shall not have occurred on
the applicable day) up to and including the last Business Day in the applicable
Calculation Period (each, a "Calculation Date") until the Calculation Agent has
so determined such closing values for five Business Days. If a Market Disruption
Event occurs on two or more of the Business Days during a Calculation Period,
the Yearly Value for the relevant year will equal the average of the values on
Business Days on which a Market Disruption Event did not occur during such
Calculation Period or, if there is only one such Business Day, the value on such
day. If a Market Disruption Event occurs on all of such Business Days during a
Calculation Period, the Yearly Value for the relevant year shall equal the
closing value of the Index on the last Business Day of the Calculation Period
regardless of whether a Market Disruption Event shall have occurred on such day.
A Yearly Value may be restated if the Substitution Event occurs after the
determination of such Yearly Value, see "Substitution of the Index".

  For purposes of determining the Final Average Value, a "Business Day" is a day
on which the Relevant Stock Exchange is open for trading. "Relevant Stock
Exchange" means the American Stock Exchange or, if a New Japan Index has been
substituted for the Japan Index, the U.S. stock exchange that publishes such New
Japan Index. All determinations made by the Calculation Agent shall be at the
sole discretion of the Calculation Agent and, absent a determination by the
Calculation Agent of a manifest error, shall be conclusive for all purposes and
binding on the Company and beneficial owners of the Securities.

  The following table illustrates, for a range of hypothetical Final Average
Values, the total amount payable at maturity for each $1,000 principal amount of
Securities.

(1)    The Initial Value.

  The above figures are for purposes of illustration only. The actual total
redemption amount received by investors will depend entirely on the actual Final
Average Value determined by the Calculation Agent as provided herein. Because
the Final Average Value will be based upon average values of the Index (which
may be a New Japan Index substituted for the Japan Index) during specified
periods in three successive years, a significant increase or decrease in the
Index as measured by the average values during the specified period in any year
may be substantially or entirely offset by the average values of the Index
during the specified periods in the other two years.

  A potential investor should review the historical performance of the Japan
Index.  The historical performance of the Japan Index should not be taken as an
indication of future performance, and no assurance can be given that the Japan
Index will increase sufficiently to cause the beneficial owners of the
Securities to receive an amount in excess of the principal amount and the
Minimum Supplemental Redemption Amount at the maturity of the Securities.

ADJUSTMENTS TO THE INDEX; MARKET DISRUPTION EVENT

  If at any time the method of calculating the Index, or the value thereof, is
changed in a material respect, or if the Index is in any other way modified so
that such Index does not, in the opinion of the Calculation Agent, fairly
represent the value of the Index had such changes or modifications not been
made, then, from and after such time, the Calculation Agent shall, at the close
of business in New York, New York, on each date that the closing value with
respect to the Final Average Value is to be calculated, make such adjustments
as, in the good faith judgment of the Calculation Agent, may be necessary in
order to arrive at a calculation of a value of a stock index comparable to the
Index as if such changes or modifications had not been made, and calculate such
closing value with reference to the Index, as adjusted. Accordingly, if the
method of calculating the Index is modified so that the value of such Index is a
fraction or a multiple of what it would have been if it had not been modified
(e.g., due to a split in the Index), then the Calculation Agent shall adjust
such Index in order to arrive at a value of the Index as if it had not been
modified (e.g., as if such split had not occurred).

                                       8
<PAGE>
 
  "Market Disruption Event" means the occurrence or existence of either of the
following events on a Business Day during a Calculation Period as determined by
the Calculation Agent:

     (i) a suspension or absence of trading on the TSE of 20% or more of the
  Underlying Stocks which then comprise the Index or a Successor Index during
  the one-half hour period preceding the close of trading on the TSE; or

     (ii) the suspension or material limitation on the Singapore International
  Monetary Exchange Ltd. (the "SIMEX"), Osaka Securities Exchange (the "OSE") or
  the Relevant Stock Exchange or any other major securities market of trading in
  futures or options contracts related to the Index during the one-half hour
  period preceding the close of trading on the applicable exchange.

  For purposes of determining whether a Market Disruption Event has occurred:
(1) a limitation on the hours or number of days of trading will not constitute a
Market Disruption Event if it results from an announced change in the regular
business hours of the relevant exchange, (2) a decision to permanently
discontinue trading in the relevant contract will not constitute a Market
Disruption Event, (3) a suspension of trading in a futures or options contract
on the Index by the Relevant Stock Exchange or other major securities market by
reason of (x) a price change exceeding limits set by the Relevant Stock Exchange
or such securities market, (y) an imbalance of orders relating to such contracts
or (z) a disparity in bid and ask quotes relating to such contracts will
constitute a suspension or material limitation of trading in futures or options
contracts related to the Index and (4) an "absence of trading" on the SIMEX,
OSE, the Relevant Stock Exchange or a major securities market on which futures
or options contracts related to the Index are traded will not include any time
when the SIMEX, OSE, the Relevant Stock Exchange or such securities market, as
the case may be, itself is closed for trading under ordinary circumstances.

SUBSTITUTION OF THE INDEX

  Movements in the Japan Index correspond generally to movements in the Nikkei
225 Index published by Nihon Keizai Shimbun, Inc., which is currently the most
widely utilized index relating to Japanese equity securities, as measured by
trading volume and open interest relating to the futures contract on such index
(the "Nikkei 225 Futures Contract"). In October of 1993, Nihon Keizai Shimbun,
Inc. commenced the calculation and publication of a new broad-based,
capitalization-weighted index referred to as the Nikkei 300 Index (the "Nikkei
300 Index"). Unlike the Nikkei 225 Index, which is a price-weighted index of 225
Japanese companies listed in the First Section of the TSE, the Nikkei 300 Index
is a capitalization-weighted index of 300 Japanese companies listed in the First
Section of the TSE. See "The Index--The New Japan Index" for a description of
the Nikkei 300 Index. The OSE announced that, if a broad-based, capitalization-
weighted index were introduced on the TSE, the OSE expected to establish a new
futures contract on such index. Although the OSE has not as of the date of this
Prospectus introduced a new futures contract on the Nikkei 300 Index, any such
contract which it may introduce at some future date is referred to herein as the
"Nikkei 300 Futures Contract".

  If the Nikkei 300 Futures Contract is introduced and publicly traded on an
exchange in Japan, and such contract develops trading volume and open interest
exceeding that of the Nikkei 225 Futures Contract, the Company believes this
would indicate that the Nikkei 300 Futures Contract will have become more widely
utilized than the Nikkei 225 Futures Contract. Therefore, in the event that a
Nikkei 300 Futures Contract is publicly traded at some future date on an
exchange in Japan and each of the additional conditions described below are
fulfilled (the occurrence of all such conditions being referred to herein as a
"Substitution Event"), a New Japan Index (as defined below) will be substituted
for the Japan Index. From and after such time, the Index used to determine the
Supplemental Redemption Amount with respect to the Notes will be such New Japan
Index. Upon the substitution of the New Japan Index for the Japan Index, the
Company will cause notice thereof to be given to Holders of the Securities. Such
notice will also state that, for purposes of calculating the Supplemental
Redemption Amount, an adjusted Initial Value will be substituted for the
original Initial Value. Such adjusted Initial Value will be calculated as
follows:

                                       9
<PAGE>
 
         Initial Value of Japan Index       
     -------------------------------------- x  current value of New Japan Index
        current value of Japan Index

where the current values of the Japan Index and of the New Japan Index will
equal their respective levels reported by the relevant exchange at the close of
business on the day that the Calculation Agent substitutes the New Japan Index
for the Japan Index. If the Substitution Event occurs after the determination of
a Yearly Value, any such Yearly Value will be restated in terms of the New Japan
Index pursuant to the following formula:

       Yearly Value prior to restatement                            
       ---------------------------------  x  adjusted Initial Value 
          original Initial Value

The Supplemental Redemption Amount will then be calculated using such restated
Yearly Value.

  A "Substitution Event" will have occurred if, as determined by the Calculation
Agent (whose opinion shall be conclusive and binding on the Company and on the
holders of the Notes), the following conditions are fulfilled:

     (a) Nikkei 300 Futures Contracts shall be introduced and publicly traded on
  an exchange in Japan; and

     (b) The American Stock Exchange or another United States securities
  exchange publishes (on a basis not less regularly than each day on which such
  exchange and the TSE are open for trading) an index (the "New Japan Index")
  which:

       (i) for a period of 90 days immediately preceding the date of the
     Substitution Event has a correlation based on daily, closing value to
     closing value, percentage changes of not less than 90% with the Nikkei 300
     Index; and

       (ii) an option, warrant or other security which has payments determined
     by reference to the New Japan Index has been approved to be listed on a
     national securities exchange by the Securities and Exchange Commission; and

     (c) Either of the following has occurred:

       (i) the Nikkei 225 Index is no longer published and/or the Nikkei 225
     Futures have been delisted from trading on the OSE; or

       (ii) the Nikkei 300 Futures Contracts publicly traded on exchanges in
     Japan have (A) greater average daily volume and (B) greater average daily
     open interest than the Nikkei 225 Futures Contracts which trade on the OSE,
     each for any three-month period prior to the date of the Substitution
     Event, commencing on a futures expiration date on the OSE and ending on the
     following futures expiration date; and

     (d) To the extent required, the Company shall have obtained any license
  necessary to use the New Japan Index as described herein. The Company has
  agreed in the Securities to use its reasonable efforts to obtain any such
  license.

Notwithstanding the above, unless the Nikkei 225 Index is no longer published
and/or the Nikkei 225 Futures Contracts shall have been delisted from trading on
the OSE, a Substitution Event will not be deemed to have occurred on any of the
180 days next preceding the maturity date of the Notes.

  All disclosure contained in this Prospectus regarding the Nikkei 225 Index,
Nikkei 225 Futures Contract, Nikkei 300 Index, Nikkei 300 Futures Contract, or
their publisher, Nihon Keizai Shimbun, Inc., is derived from publicly available
information as of January 20, 1994. Nihon Keizai Shimbun, Inc. has no
relationship with the Company

                                       10

or the Securities; it does not sponsor, endorse, authorize, sell or promote the
Securities, and has no obligation or liability in connection with the
administration, marketing or trading of the Securities.

DISCONTINUANCE OF THE INDEX

  If the American Stock Exchange discontinues publication of the Japan Index
(or, if a New Japan Index has been substituted for the Japan Index, publication
of the New Japan Index has been discontinued) and the American Stock Exchange or
another entity publishes a successor or substitute index that the Calculation
Agent determines, in its sole discretion, to be comparable to such Index (any
such index being referred to hereinafter as a "Successor Index"), then, upon the
Calculation Agent's notification of such determination to the Trustee and the
Company, the Calculation Agent will substitute the Successor Index as calculated
by the American Stock Exchange or such other entity for the Japan Index or the
New Japan Index, as the case may be, and calculate the Final Average Value as
described above under "Payment at Maturity". Upon any selection by the
Calculation Agent of a Successor Index, the Company shall cause notice thereof
to be given to Holders of the Securities.

  If the American Stock Exchange discontinues publication of the Japan Index
(or, if a New Japan Index has been substituted for the Japan Index, publication
of the New Japan Index has been discontinued) and a Successor Index is not
selected by the Calculation Agent or is no longer published on any of the
Calculation Dates, the value to be substituted for the Index for any such
Calculation Date used to calculate the Supplemental Redemption Amount at
maturity will be a value computed by the Calculation Agent for each Calculation
Date in accordance with the procedures last used to calculate the Index prior to
any such discontinuance. If a Successor Index is selected or the Calculation
Agent calculates a value as a substitute for the Index as described below, such
Successor Index or value shall be substituted for the Index for all purposes,
including for purposes of determining whether a Market Disruption Event exists.

  If the American Stock Exchange discontinues publication of the Japan Index
(or, if a New Japan Index has been substituted for the Japan Index, publication
of the New Japan Index has been discontinued) prior to the period during which
the Supplemental Redemption Amount is to be determined and the Calculation Agent
determines that no Successor Index is available at such time, then on each
Business Day until the earlier to occur of (i) the determination of the Final
Average Value and (ii) a determination by the Calculation Agent that a Successor
Index is available, the Calculation Agent shall determine the value that would
be used in computing the Supplemental Redemption Amount as described in the
preceding paragraph as if such day were a Calculation Date. The Calculation
Agent will cause notice of each such value to be published not less often than
once each month in The Wall Street Journal (or another newspaper of general
circulation), and arrange for information with respect to such values to be made
available by telephone. Notwithstanding these alternative arrangements,
discontinuance of the publication of the Index may adversely affect trading in
the Securities.

EVENTS OF DEFAULT AND ACCELERATION

  In case an Event of Default with respect to any Securities shall have occurred
and be continuing, the amount payable to a beneficial owner of a Security upon
any acceleration permitted by the Securities will be equal to: (i) the principal
amount thereof, plus (ii) an additional amount of contingent interest calculated
as though the date of early repayment were the maturity date of the Securities.
The Calculation Period used to calculate the final Yearly Value of the
Securities so accelerated will begin on the eighth scheduled Business Day next
preceding the scheduled date for such early redemption. If such final Yearly
Value is the only Yearly Value which shall have been calculated with respect to
the Securities, such final Yearly Value will be the Final Average Value. If one
or two other Yearly Values shall have been calculated with respect to the
Securities for prior years when the Securities shall have been outstanding, the
average (mean) of the final Yearly Value and such one other Yearly Value or such
two other Yearly Values, as the case may be, will be the Final Average Value.
The Minimum Supplemental Redemption Amount with respect to any such early
redemption date will be an amount equal to the interest which would have accrued
on the Securities from and including the date of original issuance to but
excluding the date of early redemption at an annualized rate of 2.33%,
calculated on a semiannual bond equivalent basis. See "Description of

                                       11
<PAGE>
 
Securities--Payment at Maturity" in this Prospectus. If a bankruptcy proceeding
is commenced in respect of the Company, the claim of the beneficial owner of a
Security may be limited, under Section 502(b)(2) of Title 11 of the United
States Code, to the principal amount of the Security plus an additional amount
of contingent interest calculated as though the date of the commencement of the
proceeding were the maturity date of the Securities.

  In case of default in payment at the maturity date of the Securities (whether
at their stated maturity or upon acceleration), from and after the maturity date
the Securities shall bear interest, payable upon demand of the beneficial owners
thereof, at the rate of 5.5% per annum (to the extent that payment of such
interest shall be legally enforceable) on the unpaid amount due and payable on
such date in accordance with the terms of the Securities to the date payment of
such amount has been made or duly provided for.

SECURITIES DEPOSITORY

  All Securities are represented by one fully registered global security (the
"Global Security"). The Global Security is deposited with, or on behalf of, The
Depository Trust Company ("DTC"), as Depository (the "Depository"), registered
in the name of DTC or a nominee thereof. Unless and until it is exchanged in
whole or in part for Securities in definitive form, the Global Security may not
be transferred except as a whole by the Depository to a nominee of such
Depository or by a nominee of such Depository to such Depository or another
nominee of such Depository or by such Depository or any such nominee to a
successor of such Depository or a nominee of such successor.

  DTC has advised the Company as follows: DTC is a limited-purpose trust company
organized under the Banking Law of the State of New York, a member of the
Federal Reserve System, a "clearing corporation" within the meaning of the New
York Uniform Commercial Code, and a "clearing agency" registered pursuant to the
provisions of Section 17A of the Exchange Act.  DTC was created to hold
securities of its participants ("Participants") and to facilitate the clearance
and settlement of securities transactions among its Participants in such
securities through electronic book-entry changes in accounts of the
Participants, thereby eliminating the need for physical movement of securities
certificates. DTC's Participants include securities brokers and dealers, banks,
trust companies, clearing corporations, and certain other organizations.

  DTC is owned by a number of Participants and by the New York Stock Exchange,
Inc., the American Stock Exchange, Inc. and the National Association of
Securities Dealers, Inc. Access to the DTC book-entry system is also available
to others, such as banks, brokers, dealers and trust companies that clear
through or maintain a custodial relationship with a Participant, either directly
or indirectly ("Indirect Participants").

  Purchases of Securities must be made by or through Participants, which will
receive a credit on the records of DTC. The ownership interest of each actual
purchaser of each Security ("Beneficial Owner") is in turn to be recorded on the
Participants' or Indirect Participants' records. Beneficial Owners will not
receive written confirmation from DTC of their purchase, but Beneficial Owners
are expected to receive written confirmations providing details of the
transaction, as well as periodic statements of their holdings, from the
Participant or Indirect Participant through which the Beneficial Owner entered
into the transaction. Ownership of beneficial interests in the Global Security
will be shown on, and the transfer of such ownership interests will be effected
only through, records maintained by DTC (with respect to interests of
Participants) and on the records of Participants (with respect to interests of
persons held through Participants). The laws of some states may require that
certain purchasers of securities take physical delivery of such securities in
definitive form. Such limits and such laws may impair the ability to own,
transfer or pledge beneficial interests in the Global Security.

  So long as DTC, or its nominee, is the registered owner of the Global
Security, DTC or its nominee, as the case may be, will be considered the sole
owner or Holder of the Securities represented by such Global Security for all
purposes under the Senior Indenture. Except as provided below, Beneficial Owners
in a Global Security will not be entitled to have the Securities represented by
such Global Securities registered in their names, will not receive or be
entitled to receive physical delivery of the Securities in definitive form and
will not be considered the owners or

                                       12
<PAGE>
 
Holders thereof under the Senior Indenture. Accordingly, each Person owning a
beneficial interest in a Global Security must rely on the procedures of DTC and,
if such Person is not a Participant, on the procedures of the Participant
through which such Person owns its interest, to exercise any rights of a Holder
under the Senior Indenture. The Company understands that under existing industry
practices, in the event that the Company requests any action of Holders or that
an owner of a beneficial interest in the Global Security desires to give or take
any action which a Holder is entitled to give or take under the Senior
Indenture, DTC would authorize the Participants holding the relevant beneficial
interests to give or take such action, and such Participants would authorize
Beneficial Owners owning through such Participants to give or take such action
or would otherwise act upon the instructions of Beneficial Owners. Conveyance of
notices and other communications by DTC to Participants, by Participants to
Indirect Participants, and by Participants and Indirect Participants to
Beneficial Owners will be governed by arrangements among them, subject to any
statutory or regulatory requirements as may be in effect from time to time.

  Payment of the principal of, and any Supplemental Redemption Amount with
respect to, Securities registered in the name of DTC or its nominee will be made
to DTC or its nominee, as the case may be, as the Holder of the Global Security
representing such Securities. None of the Company, the Trustee or any other
agent of the Company or agent of the Trustee will have any responsibility or
liability for any aspect of the records relating to or payments made on account
of beneficial ownership interests or for supervising or reviewing any records
relating to such beneficial ownership interests. The Company expects that DTC,
upon receipt of any payment of principal or any Supplemental Redemption Amount
in respect of the Global Security, will credit the accounts of the Participants
with payment in amounts proportionate to their respective holdings in principal
amount of beneficial interest in the Global Security as shown on the records of
DTC. The Company also expects that payments by Participants to Beneficial Owners
will be governed by standing customer instructions and customary practices, as
is now the case with securities held for the accounts of customers in bearer
form or registered in "street name", and will be the responsibility of such
Participants.

  If (x) any Depository is at any time unwilling or unable to continue as
Depository and a successor depository is not appointed by the Company within 60
days, (y) the Company executes and delivers to the Trustee a Company Order to
the effect that the Global Security shall be exchangeable or (z) an Event of
Default has occurred and is continuing with respect to the Securities, the
Global Security will be exchangeable for Securities in definitive form of like
tenor and of an equal aggregate principal amount, in denominations of $1,000 and
integral multiples thereof. Such definitive Securities shall be registered in
such name or names as the Depository shall instruct the Trustee. It is expected
that such instructions may be based upon directions received by the Depository
from Participants with respect to ownership of beneficial interests in such
Global Security.

                                   THE INDEX

THE JAPAN INDEX

  The Index for purposes of calculating the Supplemental Redemption Amount will
initially be the Japan Index. Unless otherwise stated, all information herein
relating to the Japan Index has been provided by the American Stock Exchange as
of January 20, 1994.  Such information reflects the policies of the American
Stock Exchange; such policies are subject to change in the discretion of the
American Stock Exchange.

  The Japan Index is a stock index calculated, published and disseminated by the
American Stock Exchange that measures the composite price performance of
selected Japanese stocks. The Japan Index as of January 20, 1994 was based on
210 highly capitalized Underlying Stocks trading on the TSE representing a broad
cross-section of Japanese industries. All 210 Underlying Stocks are stocks
listed in the First Section of the TSE. Stocks listed in the First Section are
among the most actively traded stocks on the Tokyo Stock Exchange. Options
contracts on the Japan Index are traded on the American Stock Exchange.

                                       13
<PAGE>
 
  The Japan Index is a modified, price-weighted index (i.e., an Underlying
Stock's weight in the index is based on its price per share rather than the
total market capitalization of the issuer) which is calculated by (i)
multiplying the per share price of each Underlying Stock by the corresponding
weighing factor for such Underlying Stock (a "Weight Factor"), (ii) calculating
the sum of all these products and (iii) dividing such sums by a divisor (the
"Divisor"). The Divisor, initially set in September 1990 at 9,799,460, was
9,608,946 as of January 20, 1994, and is subject to periodic adjustments as set
forth below. Each Weight Factor is computed by dividing (Yen)50 by the par value
of the relevant Underlying Stock and multiplying the result by 100, so that the
share price of each Underlying Stock when multiplied by its Weight Factor
corresponds to a share price based on a uniform par value of (Yen)50. Each
Weight Factor represents the number of shares of the related Underlying Stock
which are included in one trading unit of the Japan Index. The stock prices used
in the calculation of the Japan Index are those reported by a primary market for
the Underlying Stock (as of January 20, 1994, the TSE). The level of the Japan
Index is calculated once per day using last sale prices only (i.e., not "special
bid quotes" or "special ask quotes" which are used in connection with other
stock indices) for transactions in Underlying Stock on the TSE. The level of the
Japan Index is disseminated via the Consolidated Tape Authority Network-B
(commonly referred to as the "American Stock Exchange Tape"). The American Stock
Exchange Tape symbol for the Japan Index is "JPN".

  In order to maintain continuity in the level of the Japan Index in the event
of certain changes due to non-market factors affecting the Underlying Stocks,
such as the addition or deletion of stocks, substitution of stocks, stock
dividends, stock splits or distributions of assets to stockholders, the Divisor
used in calculating the Japan Index is adjusted in a manner designed to prevent
any instantaneous change or discontinuity in the level of the Japan Index.
Thereafter, the Divisor remains at the new value until a further adjustment is
necessary as the result of another change. As a result of each such change
affecting any Underlying Stock, the Divisor is adjusted in such a way that the
sum of all share prices immediately after such change multiplied by the
applicable Weight Factor and divided by the new Divisor (i.e., the level of the
Japan Index immediately after such change) will equal the level of the Japan
Index immediately prior to the change.

  Underlying Stocks may be deleted or added by the American Stock Exchange.
However, to maintain continuity in the Japan Index, the policy of the American
Stock Exchange is generally not to alter the composition of the Underlying
Stocks except when an Underlying Stock is deleted due to (i) bankruptcy of the
issuer, (ii) merger of the issuer with, or acquisition of the issuer by, another
company, (ii) delisting of such stock, or (iv) failure of such stock to meet,
upon periodic review by the American Stock Exchange, market value and trading
volume criteria established by the American Stock Exchange (as such may change
from time to time). Upon deletion of a stock from the Underlying Stocks, the
American Stock Exchange may select a suitable replacement for such deleted
Underlying Stock. The policy of the American Stock Exchange is to announce any
such change in advance via distribution of an information circular.

  The American Stock Exchange is under no obligation to continue the calculation
and dissemination of the Japan Index. The Securities are not sponsored,
endorsed, sold or promoted by the American Stock Exchange. No inference should
be drawn from the information contained in this Prospectus that the American
Stock Exchange makes any representation or warranty, implied or express, to the
Company, beneficial owners of the Securities or any member of the public
regarding the advisability of investing in securities generally or in the
Securities in particular or the ability of the Japan Index to track general
stock market performance. The American Stock Exchange has no obligation to take
the needs of the Company or beneficial owners of the Securities into
consideration in determining, composing or calculating the Japan Index. The
American Stock Exchange is not responsible for, and has not participated in the
determination or calculation of the equation by which the Supplemental
Redemption Amount with respect to the Securities will be determined. The
American Stock Exchange has no obligation or liability in connection with the
administration, marketing or trading of the Securities.

  The use of and reference to the Japan Index in connection with the Securities
has been consented to by the American Stock Exchange, the publisher of the Japan
Index. "Japan Index" is a service mark of the American Stock Exchange.

  None of the Company, the Calculation Agent and MLPF&S accepts any
responsibility for the calculation, maintenance or publication of the Japan
Index or any Successor Index. The American Stock Exchange disclaims all
responsibility for any errors or omissions in the calculation and dissemination
of the Japan Index or the manner in which such index is applied in determining
the Supplemental Redemption Amount with respect to the Securities.

  A potential investor should review the historical performance of the Index.
The historical performance of the Index should not be taken as an indication of
future performance, and no assurance can be given that the Index will increase
sufficiently to cause the beneficial owners of the Securities to receive an
amount in excess of the principal amount and the Minimum Supplemental Redemption
Amount at the maturity of the Securities.

THE TOKYO STOCK EXCHANGE

  The following information relating to the Tokyo Stock Exchange was derived
from information publicly available as of January 20, 1994.  The TSE is one of
the world's largest securities exchanges in terms of market capitalization.  The
TSE is a two-way, continuous pure auction market. Trading hours are from 9:00
A.M. to 11:00 A.M. and from 1:00 P.M. to 3:00 P.M., Tokyo time, Monday through
Friday.

  Due to the time zone difference, on any normal trading day the TSE will close
prior to the opening of business in New York City on the same calendar day.
Therefore, the closing level of the Japan Index on such trading day will
generally be available in the United States by the opening of business on the
same calendar day.

  The TSE has adopted certain measures intended to prevent any extreme short-
term price fluctuation resulting from order imbalances. These include daily
price floors and ceilings intended to prevent extreme fluctuations in individual
stock prices. Any stock listed on the Tokyo Stock Exchange cannot be traded at a
price outside of these limits which are stated in absolute Japanese yen, and not
percentage, limits from the closing price of the stock on the previous day. In
addition, when there is a major order imbalance in a listed stock, the TSE posts
a "special bid quote" or a "special asked quote" for that stock at a specified
higher or lower price level than the stock's last sale price in order to solicit
counter orders and balance supply and demand for the stock. Investors should
also be aware that the TSE may suspend the trading of individual stocks in
certain limited and extraordinary circumstances including, for example, unusual
trading activity in that stock. As a result, variations in the Japan Index may
be limited by price limitations on, or by suspension of trading in, individual
stocks which comprise the Japan Index which may, in turn, adversely affect the
value of the Securities or result in a Market Disruption Event. See "Description
of Securities--Adjustments to the Index; Market Disruption Event".

THE NEW JAPAN INDEX

  Under certain circumstances, a New Japan Index may be substituted for the
Japan Index for purposes of calculating the Supplemental Redemption Amount. The
New Japan Index would be an index published by the American Stock Exchange or
another United States securities exchange with a high correlation to the Nikkei
Stock Index 300. See "Substitution of the Index".

  The Nikkei Stock Index 300 is an index calculated, published and disseminated
by Nihon Keizai Shimbun, Inc., that measures the composite price performance of
stocks of 300 Japanese companies. All 300 stocks are listed in the First Section
of the TSE. Stocks listed in the First Section are among the most actively
traded stocks on the TSE. Publication of the Nikkei Stock Index 300 began on
October 8, 1993.

  The Nikkei Stock Index 300 is a market capitalization-weighted index which is
calculated by (i) multiplying the per share price of each stock included in the
Nikkei Stock Index 300 by the number of outstanding shares (excluding shares
held by the Japanese Government), (ii) calculating the sum of all these products
(such sum being hereinafter referred to as the "Aggregate Market Price"), (iii)
dividing the Aggregate Market Price by the Base Aggregate

                                       15
<PAGE>
 
Market Price (i.e. the Aggregate Market Price as of October 1, 1982) and (iv)
multiplying the result by 100. Larger companies' shares have a larger effect on
moving the entire index than smaller companies' shares.

  Although the Nikkei Stock Index 300 was first published in October 1993, Nihon
Keizai Shimbun, Inc. has calculated values for the Nikkei Stock Index 300 for
the period from October 1, 1982 through October 8, 1993. The stocks included in
the Nikkei Stock Index 300 (such stocks being hereinafter referred to as the
"Underlying Stocks") were selected from a reference group of stocks which were
selected by excluding stocks listed in the First Section of the TSE that have
relatively low market liquidity or extremely poor financial results. The
Underlying Stocks were selected from this reference group by (i) selecting from
the remaining stocks in this reference group the stocks with the largest
aggregate market value in each of 36 industrial sectors and (ii) selecting
additional stocks (with priority within each industrial sector given to the
stock with the largest aggregate market value) so that the selection ratios
(i.e. the ratio of the aggregate market value of the included stocks to that of
the stocks in the reference group) with respect to all 36 industry sectors will
be as nearly equal as possible and the total number of companies with stocks
included in the Nikkei Stock Index 300 will be 300.

  In order to maintain continuity in the level of the Nikkei Stock Index 300,
the Nikkei Stock Index 300 will be reviewed annually by Nihon Keizai Shimbun,
Inc. and the Underlying Stocks may be replaced, if necessary, in accordance with
the "deletion/addition rule". The "deletion/addition" rule provides generally
for the deletion of a stock from the Nikkei Stock Index 300 if such stock is no
longer included in the reference group or if the aggregate market value of such
stock is low relative to other stocks in the relevant industry sector. Stocks
deleted pursuant to the "deletion/addition" rule will be replaced by stocks
included in the reference group which have relatively high aggregate market
values. In addition, stocks may be added or deleted from time to time for
extraordinary reasons.

  All disclosure contained in this Prospectus regarding the Nikkei 225 Index,
Nikkei 225 Futures Contract, Nikkei Stock Index 300, Nikkei 300 Futures
Contract, or their publisher, Nihon Keizai Shimbun, Inc., is derived from
information publicly available as of January 20, 1994.  Nihon Keizai Shimbun,
Inc. has no relationship with the Company or the Securities; it does not

trading of the Securities.


                                  OTHER TERMS

GENERAL

  The Securities were issued as a series of Senior Debt Securities under the
Indenture (the "Senior Indenture"), dated as of April 1, 1983, as amended and
restated, between the Company and The Chase Manhattan Bank, formerly known as
Chemical Bank (successor by merger to Manufacturers Hanover Trust Company), as
trustee (the "Trustee"). A copy of the Senior Indenture is filed as an exhibit
to the registration statements relating to the Securities. The following
summaries of certain provisions of the Senior Indenture do not purport to be
complete and are subject to, and qualified in their entirety by reference to,
all provisions of the Senior Indenture, including the definition therein of
certain terms.

  The Senior Indenture provides that series of Senior Debt Securities may from
time to time be issued thereunder, without limitation as to aggregate principal
amount, in one or more series and upon such terms as the Company may establish
pursuant to the provisions thereof.

  The Senior Indenture provides that the Senior Indenture and the Securities are
governed by and construed in accordance with the laws of the State of New York.

  The Senior Indenture provides that the Company may issue Senior Debt
Securities with terms different from those of Senior Debt Securities previously
issued, and "reopen" a previously issued series of Senior Debt Securities and
issue additional Senior Debt Securities of such series.

                                       16
<PAGE>
 
  The Senior Debt Securities are unsecured and rank pari passu with all other
unsecured and unsubordinated indebtedness of the Company.  However, since the
Company is a holding company, the right of the Company, and hence the right of
creditors of the Company (including the Holders of Senior Debt Securities), to
participate in any distribution of the assets of any subsidiary upon its
liquidation or reorganization or otherwise is necessarily subject to the prior
claims of creditors of the subsidiary, except to the extent that claims of the
Company itself as a creditor of the subsidiary may be recognized.  In addition,
dividends, loans and advances from certain subsidiaries, including MLPF&S, to
the Company are restricted by net capital requirements under the Exchange Act
and under rules of certain exchanges and other regulatory bodies.

LIMITATIONS UPON LIENS

  The Company may not, and may not permit any Subsidiary to, create, assume,
incur or permit to exist any indebtedness for borrowed money secured by a
pledge, lien or other encumbrance (except for certain liens specifically
permitted by the Senior Indenture) on the Voting Stock owned directly or
indirectly by the Company of any Subsidiary (other than a Subsidiary which, at
the time of the incurrence of such secured indebtedness, has a net worth of less
than $3,000,000) without making effective provision whereby the Outstanding
Senior Debt Securities will be secured equally and ratably with such secured
indebtedness.

LIMITATION ON DISPOSITION OF VOTING STOCK OF, AND MERGER AND SALE OF ASSETS BY,
MLPF&S

  The Indenture provides that the Company may not sell, transfer or otherwise
dispose of any Voting Stock of MLPF&S or permit MLPF&S to issue, sell or
otherwise dispose of any of its Voting Stock, unless, after giving effect to any
such transaction, MLPF&S remains a Controlled Subsidiary (defined in the Senior
Indenture to mean a corporation more than 80% of the outstanding shares of
Voting Stock of which are owned directly or indirectly by the Company).  In
addition, the Company may not permit MLPF&S to (i) merge or consolidate, unless
the surviving company is a Controlled Subsidiary or (ii) convey or transfer its
properties and assets substantially as an entirety, except to one or more
Controlled Subsidiaries.

MERGER AND CONSOLIDATION

  The Indenture provides that the Company may consolidate or merge with or into
any other corporation, and the Company may sell, lease or convey all or
substantially all of its assets to any corporation, provided that (i) the
corporation (if other than the Company) formed by or resulting from any such
consolidation or merger or which shall have received such assets shall be a
corporation organized and existing under the laws of the United States of
America or a state thereof and shall assume payment of the principal of (and
premium, if any) and interest on the Senior Debt Securities and the performance
and observance of all of the covenants and conditions of the Senior Indenture to
be performed or observed by the Company, and (ii) the Company or such successor
corporation, as the case may be, shall not immediately thereafter be in default
under the Senior Indenture.

MODIFICATION AND WAIVER

  Modification and amendment of the Indenture may be effected by the Company and
the Trustee with the consent of the Holders of 66 2/3% in principal amount of
the Outstanding Senior Debt Securities of each series issued pursuant to such
indenture and affected thereby, provided that no such modification or amendment
may, without the consent of the Holder of each Outstanding Senior Debt Security
affected thereby, (a) change the Stated Maturity of the principal of, or any
installment of interest or Additional Amounts payable on, any Senior Debt
Security or any premium payable on the redemption thereof, or change the
Redemption Price; (b) reduce the principal amount of, or the interest or
Additional Amounts payable on, any Senior Debt Security or reduce the amount of
principal which could be declared due and payable prior to the Stated Maturity;
(c) change place or currency of any payment of principal or any premium,
interest or Additional Amounts payable on any Senior Debt Security; (d) impair
the right to institute suit for the enforcement of any payment on or with
respect to any Senior Debt Security; (e) reduce the percentage in principal
amount of the Outstanding Senior Debt Securities of any series, the consent of
whose

                                       17
<PAGE>
 
Holders is required to modify or amend the Indenture; or (f) modify the
foregoing requirements or reduce the percentage of Outstanding Senior Debt
Securities necessary to waive any past default to less than a majority.  No
modification or amendment of the Subordinated Indenture or any Subsequent
Indenture for Subordinated Debt Securities may adversely affect the rights of
any holder of Senior Indebtedness without the consent of such Holder.  Except
with respect to certain fundamental provisions, the Holders of at least a
majority in principal amount of Outstanding Senior Debt Securities of any series
may, with respect to such series, waive past defaults under the Indenture and
waive compliance by the Company with certain provisions thereof.

EVENTS OF DEFAULT

  Under the Senior Indenture, the following will be Events of Default with
respect to Senior Debt Securities of any series: (a) default in the payment of
any interest or Additional Amounts payable on any Senior Debt Security of that
series when due, continued for 30 days; (b) default in the payment of any
principal or premium, if any, on any Senior Debt Security of that series when
due; (c) default in the deposit of any sinking fund payment, when due, in
respect of any Senior Debt Security of that series; (d) default in the
performance of any other covenant of the Company contained in the Indenture for
the benefit of such series or in the Senior Debt Securities of such series,
continued for 60 days after written notice as provided in the Senior Indenture;
(e) certain events in bankruptcy, insolvency or reorganization; and (f) any
other Event of Default provided with respect to Senior Debt Securities of that
series.  The Trustee or the Holders of 25% in principal amount of the
Outstanding Senior Debt Securities of that series may declare the principal
amount (or such lesser amount as may be provided for in the Senior Debt
Securities of that series) of all Outstanding Senior Debt Securities of that
series and the interest due thereon and Additional Amounts payable in respect
thereof, if any to be due and payable immediately if an Event of Default with
respect to Senior Debt Securities of such series shall occur and be continuing
at the time of such declaration.  At any time after a declaration of
acceleration has been made with respect to Senior Debt Securities of any series
but before a judgment or decree for payment of money due has been obtained by
the Trustee, the Holders of a majority in principal amount of the Outstanding
Senior Debt Securities of that series may rescind any declaration of
acceleration and its consequences, if all payments due (other than those due as
a result of acceleration) have been made and all Events of Default have been
remedied or waived.  Any Event of Default with respect to Senior Debt Securities
of any series may be waived by the Holders of a majority in principal amount of
all Outstanding Senior Debt Securities of that series, except in a case of
failure to pay principal or premium, if any, or interest or Additional Amounts
payable on any Senior Debt Security of that series for which payment had not
been subsequently made or in respect of a covenant or provision which cannot be
modified or amended without the consent of the Holder of each Outstanding Senior
Debt Security of such series affected.

  The Holders of a majority in principal amount of the Outstanding Senior Debt
Securities of a series may 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 Senior Debt Securities of such
series, provided that such direction shall not be in conflict with any rule of
law or the Senior Indenture.  Before proceeding to exercise any right or power
under the Senior Indenture at the direction of such Holders, the Trustee shall
be entitled to receive from such Holders reasonable security or indemnity
against the costs, expenses and liabilities which might be incurred by it in
complying with any such direction.

  The Company is required to furnish to the Trustee annually a statement as to
the fulfillment by the Company of all of its obligations under the Senior
Indenture.

                    DUE DECEMBER 29, 2000 "SMART NOTES(SM)"


  On March 31, 1994, Merrill Lynch & Co., Inc. (the "Company") issued
$25,000,000 aggregate principal amount of AMEX Oil Index Stock Market Annual
Reset Term Notes due December 29, 2000 (the "Notes" or "SMART Notes").  The
Notes were issued in denominations of $1,000 and integral multiples thereof and
will mature and be repayable at 100% of the principal amount thereof on December
29, 2000. The Notes are not subject to redemption prior to maturity.

  The Company will make interest payments on the Notes for each calendar year at
a rate per annum equal to 85% (the "Participation Rate") of the average
percentage increase, if any, in the AMEX Oil Index (as defined herein) as
determined in each calendar year from the Starting Annual Value to the Ending
Average Value as further described herein (the "Average Percent Change"). Annual
payments will in no event be less than the Minimum Annual Payment of $20 per
$1,000 principal amount of Notes on a per annum basis (2% per annum).

  The "Starting Annual Value" applicable to the determination of the amount
payable in a calendar year will equal the closing value of the AMEX Oil Index on
the last AMEX Business Day (as defined below) in the immediately preceding
calendar year. The "Ending Average Value" applicable to the determination of the
amount payable in a calendar year will equal the arithmetic average (mean) of
the Quarterly Values of the AMEX Oil Index for each calendar quarter during such
year.  Interest payments will be payable on June 30 and December 31 of each year
and at maturity as described below.

  For information as to the calculation of the amount payable in any calendar
year and the calculation of the AMEX Oil Index, see "Description of Notes" and
"The AMEX Oil Index" in this Prospectus. FOR OTHER INFORMATION THAT SHOULD BE
CONSIDERED BY PROSPECTIVE INVESTORS, SEE "RISK FACTORS" BEGINNING ON PAGE 3 OF

                                  RISK FACTORS
INTEREST PAYMENTS

  If the Ending Average Value applicable to a December Payment Date does not
exceed the Starting Annual Value applicable to such December Payment Date by
more than approximately 2.35%, beneficial owners of the Notes will receive only
the Minimum Annual Payment on such December Payment Date, even if the value of
the AMEX Oil Index at some point between the determination of the applicable
Starting Annual Value and the determination of the applicable Ending Average
Value exceeded such Starting Annual Value by more than approximately 2.35%. The
annual amount payable on the Notes based on the AMEX Oil Index is limited to the
Participation Rate multiplied by the percentage increase, if any, between the
Starting Annual Value and the Ending Average Value for such year.

  Beneficial owners of the Notes will receive total annual payments equal to not
less than the Minimum Annual Payment, and will be repaid 100% of the principal
amount of the Notes at maturity. Beneficial owners of Notes may receive interest
payments with respect to the Notes equal to only the Minimum Annual Payment for
each year, and such interest payments are below what the Company would pay as
interest as of the date hereof if the Company issued non-callable senior debt
securities with a similar maturity as that of the Notes. The payment of
additional amounts on the Notes is subject to the conditions described under
"Description of Notes--Interest Payments". The

                                       3
<PAGE>
 
return of principal of the Notes at maturity and the payment of the Minimum
Annual Payment are not expected to reflect the full opportunity costs implied by
inflation or other factors relating to the time value of money.

  The amount payable on the Notes based on the AMEX Oil Index will not produce
the same return as if the stocks underlying the AMEX Oil Index were purchased
and held for a similar period because of the following: (i) the AMEX Oil Index
does not reflect the payment of dividends on the stocks underlying it, (ii) the
annual amount payable is limited to the Participation Rate multiplied by the
percentage increase in the AMEX Oil Index during any relevant period, subject to
the Minimum Annual Payment, (iii) the Ending Average Value may not reflect the
full percentage increase in the AMEX Oil Index during any relevant period
because it is an average of the AMEX Oil Index at various points in time and
(iv) the amounts payable on the Notes do not reflect changes in the AMEX Oil
Index for the period between the determination of an Ending Average Value and
the determination of the next succeeding Starting Annual Value.

  The Indenture provides that the Indenture and the Notes are governed by and
construed in accordance with the laws of the state of New York. Under present
New York law, the maximum rate of interest is 25% per annum on a simple interest
basis. This limit may not apply to Notes in which $2,500,000 or more has been
invested. While the company believes that New York law would be given effect by
a state or federal court sitting outside of New York, state laws frequently
regulate the amount of interest that may be charged to and paid by a borrower
(including, in some cases, corporate borrowers). It is suggested that
prospective investors consult their personal advisors with respect to the
applicability of such laws. The Company has covenanted for the benefit of the
beneficial owners of the Notes, to the extent permitted by law, not to claim
voluntarily the benefits of any laws concerning usurious rates of interest
against a beneficial owner of the Notes.

TRADING

  The Notes have been listed on the American Stock Exchange under the symbol
"MOI.F".  It is expected that the secondary market for the Notes (including
prices in such market) will likely be affected by the creditworthiness of the
Company and by a number of other factors. It is possible to view the Notes as
the economic equivalent of a debt obligation plus a series of cash settlement
options; however, the Notes may trade in the secondary market at a discount from
the aggregate value of such economic components, if such economic components
were valued and capable of being traded separately.

  The trading values of the Notes may be affected by a number of interrelated
factors, including those listed below. The following is the expected theoretical
effect on the trading value of the Notes of each of the factors listed below.
The following discussion of each separate factor generally assumes that all
other factors are held constant, although the actual interrelationship between
certain of such factors is complex.

  Relative Level of the AMEX Oil Index.   The trading value of the Notes is
expected to depend significantly on the extent of the excess of the expected
Ending Average Value for a calendar year over the Starting Annual Value
applicable to such calendar year. If, however, Notes are sold at a time when the
AMEX Oil Index (or the estimated Ending Average Value if such value were
calculated at such time) exceeds the Starting Annual Value, the sale price may
nevertheless be at a discount from the amount expected to be payable to the
beneficial owner if such excess were to prevail until the next December Payment
Date. Furthermore, the price at which a beneficial owner will be able to sell
Notes prior to a December Payment Date may be at a discount, which could be
substantial, from the principal amount thereof, if, at such time, the AMEX Oil
Index is below, equal to or not sufficiently above the Annual Starting Value
applicable to such December Payment Date. The level of the AMEX Oil Index will
depend on the prices of the stocks underlying such Index which, in turn, will be
affected by factors affecting the oil industry, see "The AMEX Oil Index--Oil
Industry Sector".

  Volatility of the AMEX Oil Index.   If the volatility of the AMEX Oil Index
increases, the trading value of the Notes is expected to increase. If the
volatility of the AMEX Oil Index decreases, the trading value of the Notes is
expected to decrease.

  U.S. Interest Rates.   In general, if U.S. interest rates increase, the value
of the Notes is expected to decrease. If U.S. interest rates decrease, the value
of the Notes is generally expected to increase. Interest rates may also affect

                                       4
<PAGE>
 
the U.S. economy, and, in turn, the level of the AMEX Oil Index. Rising interest
rates may lower the level of the AMEX Oil Index and, thus, the value of the
Notes. Falling interest rates may increase the level of the AMEX Oil Index and,
thus, may increase the value of the Notes.

  Time Remaining to December Payment Dates.   The Notes may trade at a value
above that which may be inferred from the level of U.S. interest rates and the
AMEX Oil Index. This difference will reflect a "time premium" due to
expectations concerning the level of the AMEX Oil Index during the period prior
to each December Payment Date. As the time remaining to each December Payment
Date decreases, however, this time premium may decrease, thus decreasing the
trading value of the Notes.

  Time Remaining to Maturity.   As the number of remaining December Payment
Dates decreases, the cumulative value of all the annual rights to receive an
amount that reflects participation in the payments in excess of the Minimum
Annual Payment will decrease, thus decreasing the value of the Notes.

  Dividend Rates.   A number of complex relationships between the relative
values of the Notes and dividend rates are likely to exist. If dividend rates on
the stocks comprising the AMEX Oil Index increase, the value of the annual right
to receive an amount that reflects participation in the average appreciation of
the AMEX Oil Index above the Starting Annual Value is expected to decrease.
Consequently the value of the Notes is expected to decrease. Conversely, if
dividend rates on the stocks comprising the AMEX Oil Index decrease, the value
of the annual right to receive such an amount is expected to increase and,
therefore, the value of the Notes is expected to increase. In general, however,
because the majority of issuers of stocks underlying the AMEX Oil Index are
organized in the United States, rising U.S. corporate dividend rates may
increase the AMEX Oil Index and, in turn, increase the value of the Notes.
Conversely, falling U.S. dividend rates may decrease the AMEX Oil Index and, in
turn, decrease the value of the Notes.

OTHER CONSIDERATIONS

  It is suggested that prospective investors who consider purchasing the Notes
should reach an investment decision only after carefully considering the
suitability of the Notes in light of their particular circumstances. Investors
should also consider the tax consequences of investing in the Notes and should
consult their tax advisors.

<PAGE>
 
                              DESCRIPTION OF NOTES

GENERAL

  The Notes were issued as a series of Senior Debt Securities under the Senior
Indenture, dated as of April 1, 1983, as amended and restated, as described
below.  The Notes will mature, and the principal of the Notes will be repayable
at par, on December 29, 2000.

  The Notes are not subject to redemption prior to maturity by the Company or at
the option of any beneficial owner. Upon the occurrence of an Event of Default
with respect to the Notes, however, beneficial owners of the Notes or the Senior
Debt Trustee may accelerate the maturity of the Notes, as described under
"Description of Notes--Events of Default and Acceleration" and "Other Terms--
Events of Default" in this Prospectus.

  The Notes are transferable in denominations of $1,000 and integral multiples
thereof.

INTEREST PAYMENTS

  For each full calendar year, the Company will pay interest in an amount equal
to the following for each $1,000 principal amount of Notes:

              $1,000 x Average Percent Change x Participation Rate

provided, however, that the per annum amount payable as a result of the
foregoing on the Notes will not be less than the Minimum Annual Payment of $20
per $1,000 principal amount of Notes on a per annum basis (2% per annum). The
Participation Rate equals 85%.

  The "Average Percent Change" applicable to the determination of the amount
payable in any calendar year will equal:

                 Ending Average Value -- Starting Annual Value
                 ---------------------------------------------
                             Starting Annual Value

The "Starting Annual Value" applicable to the determination of the amount
payable in a calendar year will equal the closing value of the AMEX Oil Index on
the last AMEX Business Day in the immediately preceding calendar year as
determined by State Street Bank and Trust Company (the "Calculation Agent"). The
"Ending Average Value" applicable to the determination of the amount payable in
a calendar year will equal the arithmetic average (mean) of the Quarterly Values
of the AMEX Oil Index for each calendar quarter during such year as determined
by the Calculation Agent. The "Quarterly Value" for any of the first three
calendar quarters in a calendar year will be the closing value of the AMEX Oil
Index on the last scheduled AMEX Business Day in any such calendar quarter;
provided, however, that if a Market Disruption Event has occurred on such last
scheduled AMEX Business Day in such calendar quarter, the Quarterly Value for
such calendar quarter will be the closing value of the AMEX Oil Index on the
next succeeding scheduled AMEX Business Day regardless of whether a Market
Disruption Event occurs on such day. The "Quarterly Value" for the fourth
calendar quarter in a calendar year will be the closing value of the AMEX Oil
Index on the seventh scheduled AMEX Business Day preceding the end of such
calendar quarter; provided, however, that if a Market Disruption Event has
occurred on such seventh scheduled AMEX Business Day, the Quarterly Value for
such calendar quarter will be the closing value of the AMEX Oil Index on the
sixth scheduled AMEX Business Day preceding the end of such calendar quarter
regardless of whether a Market Disruption Event occurs on such day. The
Calculation Agent will determine scheduled AMEX Business Days.

  If the Ending Average Value applicable to such December Payment Date does not
exceed the Annual Starting Value by more than approximately 2.35%, beneficial
owners of the Notes will receive only the Minimum Annual Payment on such
December Payment Date, even if the value of the AMEX Oil Index at some point
between the determination of the applicable Starting Annual Value and the
determination of the applicable Ending Average Value exceeded such Starting
Annual Value by more than approximately 2.35%.

                                       6
<PAGE>
 
  Any day on which a Starting Annual Value or a closing value of the AMEX Oil
Index for a calendar quarter is required to be calculated is referred to herein
as a "Calculation Day". An "AMEX Business Day" is a day on which the American
Stock Exchange is open for trading. All determinations made by the Calculation
Agent shall be at the sole discretion of the Calculation Agent and, in the
absence of manifest error, shall be conclusive for all purposes and binding on
the Company and beneficial owners of the Notes. All percentages resulting from
any calculation on the Notes will be rounded to the nearest one hundred-
thousandth of a percentage point, with five one millionths of a percentage point
rounded upwards (e.g., 9.876545% (or .09876545) would be rounded to 9.87655% (or
 .0987655)), and all dollar amounts used in or resulting from such calculation
will be rounded to the nearest cent (with one-half cent being rounded upwards).

ADJUSTMENTS TO THE INDEX; MARKET DISRUPTION EVENT

  If at any time the method of calculating the AMEX Oil Index, or the value
thereof, is changed in a material respect, or if the AMEX Oil Index is in any
other way modified so that such index does not, in the opinion of the
Calculation Agent, fairly represent the value of the AMEX Oil Index had such
changes or modifications not been made, then, from and after such time, the
Calculation Agent shall, at the close of business in New York, New York, on each
Calculation Day, make such adjustments as, in the good faith judgment of the
Calculation Agent, may be necessary in order to arrive at a calculation of a
value of a stock index comparable to the AMEX Oil Index as if such changes or
modifications had not been made, and calculate such closing value with reference
to the AMEX Oil Index, as adjusted. Accordingly, if the method of calculating
the AMEX Oil Index is modified so that the value of such index is a fraction or
a multiple of what it would have been if it had not been modified (e.g., due to
a split in the Index), then the Calculation Agent shall adjust such index in
order to arrive at a value of the AMEX Oil Index as if it had not been modified
(e.g., as if such split had not occurred).

  "Market Disruption Event" means either of the following events, as determined
  by the Calculation Agent:

    (i)  the suspension or material limitation (limitations pursuant to New York
  Stock Exchange Rule 80A (or any applicable rule or regulation enacted or
  promulgated by the New York Stock Exchange, the American Stock Exchange, or
  the Commission of similar scope as determined by the Calculation Agent) on
  trading during significant market fluctuations shall be considered "material"
  for purposes of this definition), in each case, during the last half hour of
  trading in any of the component stocks, or depository receipts representing
  such stocks, included in the AMEX Oil Index on any national securities
  exchange in the United States, or

    (ii)  the suspension or material limitation, in each case during the last
  half hour of trading (whether by reason of movements in price exceeding levels
  permitted by the relevant exchange or otherwise), in (A) futures contracts
  related to the AMEX Oil Index which are traded on any exchange or board of
  trade in the United States or (B) option contracts related to the AMEX Oil
  Index which are traded on the American Stock Exchange.

  For the purposes of this definition, a limitation on the hours in a trading
day and/or number of days of trading will not constitute a Market Disruption
Event if it results from an announced change in the regular business hours of
the relevant exchange.

INTEREST PAYMENT DATES

  The Company will make semiannual interest payments on the Notes on June 30 of
each year ("June Payment Dates") and December 31 of each year and at maturity
("December Payment Dates"), except as provided below, to the persons in whose
names the Notes are registered on the immediately preceding June 29 or December
30, and, at maturity, to the person to whom the principal is payable. For each
Note, the Company will pay half of the Minimum Annual Payment for each calendar
year on the June Payment Date, and will pay the balance of the annual amount
payable on such Note for such year on the December Payment Date.

  Notwithstanding the foregoing, if it is known at least three Business Days
prior to December 31 that December 31 will not be a Business Day, the amount
payable by the Company with respect to a December Payment Date for the Notes
will be made on the Business Day immediately preceding such December 31 to the
persons in whose

                                       7
<PAGE>
 
names the Notes are registered on the second Business Day immediately preceding
such December 31.

UNAVAILABILITY OF THE AMEX OIL INDEX

  If the AMEX discontinues publication of the AMEX Oil Index and the AMEX or
another entity publishes a successor or substitute index that the Calculation
Agent determines, in its sole discretion, to be comparable to the AMEX Oil Index
(any such index being referred to hereinafter as a "Successor Index"), then,
upon the Calculation Agent's notification of such determination to the Trustee
and the Company, the Calculation Agent will substitute the Successor Index as
calculated by the AMEX or such other entity for the AMEX Oil Index and calculate
the annual amount payable as described above under "Interest Payments". Upon any
selection by the Calculation Agent of a Successor Index, the Company shall cause
notice thereof to be given to Holders of the Notes.

  If the AMEX discontinues publication of the AMEX Oil Index and a Successor
Index is not selected by the Calculation Agent or is no longer published on any
of the Calculation Days, the value to be substituted for the AMEX Oil Index for
any such Calculation Day used to calculate the annual amount payable will be a
value computed by the Calculation Agent for each Calculation Day in accordance
with the procedures last used to calculate the AMEX Oil Index prior to any such
discontinuance. If a Successor Index is selected or the Calculation Agent
calculates a value as a substitute for the AMEX Oil Index such Successor Index
or value shall be substituted for the AMEX Oil Index for all purposes, including
for purposes of determining whether a Market Disruption Event exists.

  If the AMEX discontinues publication of the AMEX Oil Index prior to the period
during which the amount payable with respect to any year is to be determined and
the Calculation Agent determines that no Successor Index is available at such
time, then on each AMEX Business Day until the earlier to occur of (i) the
determination of the amount payable with respect to such year or (ii) a
determination by the Calculation Agent that a Successor Index is available, the
Calculation Agent shall determine the value that would be used in computing the
amount payable with respect to such year as described in the preceding paragraph
as if such day were a Calculation Day. The Calculation Agent will cause notice
of each such value to be published not less often than once each month in the
Wall Street Journal (or another newspaper of general circulation), and arrange
for information with respect to such values to be made available by telephone.
Notwithstanding these alternative arrangements, discontinuance of the
publication of the AMEX Oil Index may adversely affect trading in the Notes.

EVENTS OF DEFAULT AND ACCELERATION

  In case an Event of Default with respect to any Notes shall have occurred and
be continuing, the amount payable to a beneficial owner of a Note upon any
acceleration permitted by the Notes, will equal: (i) the principal amount
thereof, plus (ii) an additional amount, if any, of interest calculated as
though the date of early repayment were a December Payment Date and prorated
through such date of early repayment on the basis of a year consisting of 360
days of twelve 30-day months. If Quarterly Values have been calculated prior to
the early redemption date for the calendar year in which such early redemption
date occurs, such Quarterly Values shall be averaged with the value of the AMEX
Oil Index determined with respect to such date of early redemption. If no
Quarterly Values have been calculated prior to the early redemption date for the
calendar year in which the early redemption date occurs, the Ending Average
Value for such calendar year will be the value of the AMEX Oil Index determined
with respect to such date of early redemption. The Minimum Supplemental
Redemption Amount with respect to any such early redemption date will be an
amount equal to the interest which would have accrued on the Notes from and
including January 1 in the calendar year in which such early redemption date
occurs, to but excluding the date of early redemption at an annualized rate of
2%, calculated on a semiannual bond equivalent basis. If a bankruptcy proceeding
is commenced in respect of the Company, the claim of the beneficial owner of a
Note may be limited, under Section 502(b)(2) of Title 11 of the United States
Code, to the principal amount of the Note plus an additional amount, if any, of
contingent interest calculated as though the date of the commencement of the
proceeding were the maturity date of the Notes.

  In case of default in payment at the maturity date of the Notes (whether at
their stated maturity or upon acceleration), from and after the maturity date
the Notes shall bear interest, payable upon demand of the Holders thereof, at
the rate of 7% per annum (to the extent that payment of such interest shall be
legally enforceable) on

                                       8

the unpaid amount due and payable on such date in accordance with the terms of
the Notes to the date payment of such amount has been made or duly provided for.

SECURITIES DEPOSITORY

  The Notes are represented by one fully registered global security (the "Global
Security"). Such Global Security has been deposited with, or on behalf of, The
Depository Trust Company, as Securities Depository (the "Securities
Depository"), registered in the name of the Securities Depository or a nominee
thereof. Unless and until it is exchanged in whole or in part for Securities in
definitive form, the Global Security may not be transferred except as a whole by
the Securities Depository to a nominee of such Securities Depository or by a
nominee of such Securities Depository to such Securities Depository or another
nominee of such Securities Depository or by such Securities Depository or any
such nominee to a successor of such Securities Depository or a nominee of such
successor.

  The Securities Depository has advised the Company as follows: The Securities
Depository is a limited-purpose trust company organized under the Banking Law of
the State of New York, a member of the Federal Reserve System, a "clearing
corporation" within the meaning of the New York Uniform Commercial Code, and a
"clearing agency" registered pursuant to the provisions of Section 17A of the
Exchange Act.  The Securities Depository was created to hold securities of its
participants ("Participants") and to facilitate the clearance and settlement of
securities transactions among its Participants in such securities through
electronic book-entry changes in accounts of the Participants, thereby
eliminating the need for physical movement of securities certificates. The
Securities Depository's Participants include securities brokers and dealers,
banks, trust companies, clearing corporations, and certain other organizations.
The Securities Depository is owned by a number of Participants and by the New
York Stock Exchange, Inc., the American Stock Exchange, Inc. and the National
Association of Securities Dealers, Inc.  Access to the Securities Depository
book-entry system is also available to others, such as banks, brokers, dealers
and trust companies that clear through or maintain a custodial relationship with
a Participant, either directly or indirectly ("Indirect Participants").

  Purchases of Notes must be made by or through Participants, which will receive
a credit on the records of the Securities Depository. The ownership interest of
each actual purchaser of each Note ("Beneficial Owner") is in turn to be
recorded on the Participants' or Indirect Participants' records. Beneficial
Owners will not receive written confirmation from the Securities Depository of
their purchase, but Beneficial Owners are expected to receive written
confirmations providing details of the transaction, as well as periodic
statements of their holdings, from the Participant or Indirect Participant
through which the Beneficial Owner entered into the transaction. Ownership of
beneficial interests in such Global Security will be shown on, and the transfer
of such ownership interests will be effected only through, records maintained by
the Securities Depository (with respect to interests of Participants) and on the
records of Participants (with respect to interests of persons held through
Participants). The laws of some states may require that certain purchasers of
securities take physical delivery of such securities in definitive form. Such
limits and such laws may impair the ability to own, transfer or pledge
beneficial interests in Global Securities.

  So long as the Securities Depository, or its nominee, is the registered owner
of the Global Security, the Securities Depository or its nominee, as the case
may be, will be considered the sole owner or Holder of the Notes represented by
such Global Security for all purposes under the Senior Indenture. Except as
provided below, Beneficial Owners in the Global Security will not be entitled to
have the Notes represented by such Global Security registered in their names,
will not receive or be entitled to receive physical delivery of the Notes in
definitive registered form and will not be considered the owners or Holders
thereof under the Senior Indenture. Accordingly, each Person owning a beneficial
interest in a Global Security must rely on the procedures of the Securities
Depository and, if such Person is not a Participant, on the procedures of the
Participant through which such Person owns its interest, to exercise any rights
of a Holder under the Senior Indenture. The Company understands that under
existing industry practices, in the event that the Company requests any action
of Holders or that an owner of a beneficial interest in the Global Security
desires to give or take any action which a Holder is entitled to give or take
under the Senior Indenture, the Securities Depository would authorize the
Participants holding the relevant beneficial interests to give or take such
action, and such Participants would authorize Beneficial Owners owning through
such Participants to give or take such action or would otherwise act upon the
instructions of beneficial owners. Conveyance of notices and other
communications by the Securities Depository to Participants, by Participants to
Indirect Participants, and by Participants and Indirect Participants to
Beneficial Owners will be governed by arrangements among them, subject to any
statutory or regulatory requirements as may be in effect

                                       9
<PAGE>
 
from time to time.

  Payment of the principal of, and amounts payable on any June Payment Date or
December Payment Date with respect to Notes registered in the name of the
Securities Depository or its nominee, will be made to the Securities Depository
or its nominee, as the case may be, as the Holder of the Global Security
representing such Notes. None of the Company, the Trustee or any other agent of
the Company or agent of the Trustee will have any responsibility or liability
for any aspect of the records relating to or payments made on account of
beneficial ownership interests or for supervising or reviewing any records
relating to such beneficial ownership interests. The Company expects that the
Securities Depository, upon receipt of any payment of principal or amounts
payable on any June Payment Date or December Payment Date in respect of the
Global Security, will credit the accounts of the Participants with payment in
amounts proportionate to their respective holdings in principal amount of
beneficial interest in such Global Security as shown on the records of the
Securities Depository. The Company also expects that payments by Participants to
Beneficial Owners will be governed by standing customer instructions and
customary practices, as is now the case with securities held for the accounts of
customers in bearer form or registered in "street name", and will be the
responsibility of such Participants.

  If (x) the Securities Depository is at any time unwilling or unable to
continue as Securities Depository and a successor depository is not appointed by
the Company within 60 days, (y) the Company executes and delivers to the Trustee
a Company Order to the effect that the Global Security shall be exchangeable or
(z) an Event of Default has occurred and is continuing with respect to the
Notes, the Global Security will be exchangeable for Notes in definitive form of
like tenor and of an equal aggregate principal amount, in denominations of
$1,000 and integral multiples thereof. Such definitive Notes shall be registered
in such name or names as the Securities Depository shall instruct the Trustee.
It is expected that such instructions may be based upon directions received by
the Securities Depository from Participants with respect to ownership of
beneficial interests in such Global Security.


                               THE AMEX OIL INDEX

GENERAL

  All information relating to the AMEX Oil Index was derived from information
publicly available as of March 24, 1994.  The AMEX Oil Index is a price-weighted
stock index (i.e., an Underlying Stock's weight in the index is based on its
price per share rather than the total market capitalization of the issuer)
calculated, published and disseminated by the AMEX that measures the composite
price performance of selected common stocks of widely-held corporations involved
in various segments of the oil industry. The AMEX Oil Index was originally
published by the AMEX as the Oil and Gas Index. In September 1984, the AMEX
changed the Oil and Gas Index from a market-weighted index to a price-weighted
index and deleted all companies engaged exclusively in gas exploration and
production activities. The Oil and Gas Index was then renamed the Oil Index. At
March 24, 1994, the calculation of the value of the AMEX Oil Index was based on
the relative value of the aggregate market price of the common stocks of sixteen
companies engaged in various segments of the oil industry.

  The AMEX may from time to time, with approval of the Commission, add companies
to, or delete companies from, the AMEX Oil Index to fulfill the above-stated
intention of providing an indication of price movements of common stock of
corporations engaged in various segments of the oil industry. The level of the
AMEX Oil Index is calculated once per day using last sale prices only (i.e., not
special "bid quotes" or special "ask quotes" which are used in connection with
other stock indices). The level of the AMEX Oil Index is disseminated via the
Consolidated Tape Authority Network-B (commonly referred to as the "AMEX Tape").
The AMEX Tape Symbol for the AMEX Oil Index is "XOI".

                                       10
<PAGE>
 
COMPUTATION OF THE AMEX OIL INDEX

  At March 24, 1994, the AMEX computed the AMEX Oil Index as of a particular
time as follows:

  (1) the market price of one share of each component stock is determined as of
such time;

  (2) the market prices of all component stocks as of such time (as determined
under clause (1) above) are aggregated;

  (3) the aggregate amount (as determined under clause (2) above) is divided by
3.47874 (the "Divisor").

  While the AMEX employed the above methodology to calculate the AMEX Oil Index
at March 24, 1994, no assurance can be given that the AMEX will not modify or
change such methodology in a manner that may affect the amounts payable on any
December Payment Date to beneficial owners of the Notes.

  In order to maintain continuity in the level of the AMEX Oil Index in the
event of certain changes due to non-market factors affecting the Underlying
Stocks, such as the addition or deletion of stocks, substitution of stocks,
stock dividends, stock splits or distributions of assets to stockholders, the
Divisor used in calculating the AMEX Oil Index is adjusted in a manner designed
to prevent any instantaneous change or discontinuity in the level of the AMEX
Oil Index. Thereafter, the Divisor remains at the new value until a further
adjustment is necessary as the result of another change. As a result of each
such change affecting any component stock, the Divisor is adjusted in such a way
that the level of the AMEX Oil Index immediately after such change will equal
the level of the AMEX Oil Index immediately prior to the change.

  Component stocks may be deleted or added by the AMEX with approval of the
Commission.  However, to maintain continuity in the AMEX Oil Index, the policy
of the AMEX is generally not to alter the composition of the component stocks
except when a component Stock is deleted due to (i) bankruptcy of the issuer,
(ii) merger of the issuer with, or acquisition of the issuer by, another
company, (iii) delisting of such stock, or (iv) failure of such stock to meet,
upon periodic review by the AMEX, market value and trading volume criteria
established by the AMEX (as such may change from time to time). Upon deletion of
a stock from the component stocks, the AMEX may select a suitable replacement
for such deleted component stock. The policy of the AMEX is to announce any such
change in advance via distribution of an information circular.

  The use of and reference to the AMEX Oil Index in connection with the Notes
has been consented to by the AMEX, the publisher of the AMEX Oil Index and, in
connection with such consent, the AMEX has requested that the following
information appear in this Prospectus. The AMEX is under no obligation to
continue the calculation and dissemination of the AMEX Oil Index. The Notes are
not sponsored, endorsed, sold or promoted by the AMEX. No inference should be
drawn from the information contained in this Prospectus that the AMEX makes any
representation or warranty, implied or express, to the Company, beneficial
owners of the Notes or any member of the public regarding the advisability of
investing in securities generally or in the Notes in particular or the ability
of the AMEX Oil Index to track general stock market performance. The AMEX has no
obligation to take the needs of the Company or beneficial owners of the Notes
into consideration in determining, composing or calculating the AMEX Oil Index.
The AMEX is not responsible for, and has not participated, in the determination
or calculation of the equation by which the Notes with respect to the annual
payments will be determined. The AMEX has no obligation or liability in
connection with the administration, marketing or trading of the Notes. The AMEX
disclaims all responsibility for any errors or omissions in the calculation and
dissemination of the AMEX Oil Index or the manner in which such index is applied
in determining the annual payments with respect to the Notes.

  None of the Company, the Calculation Agent, MLPF&S nor the Trustee accepts any
responsibility for the calculation, maintenance or publication of the AMEX Oil
Index or any Successor Index.

  A potential investor should review the historical prices of the securities
underlying the Amex Oil Index.  The historical prices of such securities should
not be taken as an indication of future performance, and no assurance can be
given that the prices of such securities will increase sufficiently to cause the
beneficial owners of the Notes to receive an amount in excess of the Minimum
Annual Payment on any December Payment Date and at the maturity of the Notes.

OIL INDUSTRY SECTOR

  The oil industry is subject to varying degrees of regulatory, political and
economic risk which may affect the price of the stocks of the companies engaged
in the industry. Such risks depend on a number of factors including the
countries in which a particular company conducts its activities, evolving levels
of governmental regulation, and litigation with respect to environmental and
other matters. All segments of the oil industry are competitive, including
manufacturing, distribution and marketing of petroleum products and
petrochemicals. In addition, the oil industry competes with other industries in
supplying the energy needs of various types of consumers. Refining margins (the
difference between the price of products and the price of crude oil) and
marketing margins (the difference between the wholesale and retail price of
petroleum products) also affect companies engaged in the oil industry.

  The profitability of companies engaged in the oil industry is directly
affected by the worldwide price of oil and related petroleum products which, in
turn, depends upon the worldwide demand for oil and related petroleum products.

  Environmental regulation is a significant factor affecting profitability of
companies engaged in the oil industry. In the U.S., companies engaged in the oil
industry are subject to substantial environmental regulation by federal, state,
and local authorities. Federal regulations include the Comprehensive
Environmental Response, Compensation and Liability Act of 1980, as amended
(often referred to as CERCLA or Superfund), the Superfund Amendments and
Reauthorizations Act of 1986, and the Resource Conservation Recovery Act of
1976.

  In the United States and elsewhere, various laws and regulations are either
now in force, in standby status or under consideration, with respect to such
matters as price controls, crude oil and refined product allocations, refined
product specifications, environmental, health and safety regulations,
retroactive and prospective tax increases, cancellation of contract rights,
expropriation of property, divestiture of certain operations, foreign exchange
rate restrictions as to the convertibility of currencies, tariffs and other
international trade restrictions. Other regulations such as the U.S. Federal
Clean Air Act Amendments of 1990 may have a substantial impact on companies
engaged in the oil industry despite the fact that they do not impose direct
regulations. Finally, regional regulations like those proposed by California's
South Coast Air Quality Management District may have substantial effects on the
oil industry as well.


                                  OTHER TERMS
GENERAL

  The Notes were issued as a series of Senior Debt Securities under the
Indenture (the "Senior Indenture"), dated as of April 1, 1983, as amended and
restated, between the Company and The Chase Manhattan Bank, formerly known as
Chemical Bank (successor by merger to Manufacturers Hanover Trust Company), as
trustee (the "Trustee"). A copy of the Senior Indenture is filed as an exhibit
to the registration statements relating to the Notes.  The following summaries
of certain provisions of the Senior Indenture do not purport to be complete and
are subject to, and qualified in their entirety by reference to, all provisions
of the Senior Indenture, including the definition therein of certain terms.

  The Senior Indenture provides that series of Senior Debt Securities may from
time to time be issued thereunder, without limitation as to aggregate principal
amount, in one or more series and upon such terms as the Company may establish
pursuant to the provisions thereof.

  The Senior Indenture provides that the Senior Indenture and the Notes are
governed by and construed in accordance with the laws of the State of New York.

  The Senior Indenture provides that the Company may issue Senior Debt
Securities with terms different from those of Senior Debt Securities previously
issued, and "reopen" a previously issued series of Senior Debt Securities and
issue additional Senior Debt Securities of such series.

  The Senior Debt Securities are unsecured and rank pari passu with all other
unsecured and unsubordinated indebtedness of the Company.  However, since the
Company is a holding company, the right of the Company, and hence the right of
creditors of the Company (including the Holders of Senior Debt Securities), to
participate in any distribution of the assets of any subsidiary upon its
liquidation or reorganization or otherwise is necessarily subject to the prior
claims

                                       12
<PAGE>
 
of creditors of the subsidiary, except to the extent that claims of the Company
itself as a creditor of the subsidiary may be recognized.  In addition,
dividends, loans and advances from certain subsidiaries, including MLPF&S, to
the Company are restricted by net capital requirements under the Exchange Act
and under rules of certain exchanges and other regulatory bodies.

LIMITATIONS UPON LIENS

  The Company may not, and may not permit any Subsidiary to, create, assume,
incur or permit to exist any indebtedness for borrowed money secured by a
pledge, lien or other encumbrance (except for certain liens specifically
permitted by the Senior Indenture) on the Voting Stock owned directly or
indirectly by the Company of any Subsidiary (other than a Subsidiary which, at
the time of the incurrence of such secured indebtedness, has a net worth of less
than $3,000,000) without making effective provision whereby the Outstanding
Senior Debt Securities will be secured equally and ratably with such secured
indebtedness.

LIMITATION ON DISPOSITION OF VOTING STOCK OF, AND MERGER AND SALE OF ASSETS BY,
MLPF&S

  The Indenture provides that the Company may not sell, transfer or otherwise
dispose of any Voting Stock of MLPF&S or permit MLPF&S to issue, sell or
otherwise dispose of any of its Voting Stock, unless, after giving effect to any
such transaction, MLPF&S remains a Controlled Subsidiary (defined in the Senior
Indenture to mean a corporation more than 80% of the outstanding shares of
Voting Stock of which are owned directly or indirectly by the Company).  In
addition, the Company may not permit MLPF&S to (i) merge or consolidate, unless
the surviving company is a Controlled Subsidiary or (ii) convey or transfer its
properties and assets substantially as an entirety, except to one or more
Controlled Subsidiaries.

MERGER AND CONSOLIDATION

  The Indenture provides that the Company may consolidate or merge with or into
any other corporation, and the Company may sell, lease or convey all or
substantially all of its assets to any corporation, provided that (i) the
corporation (if other than the Company) formed by or resulting from any such
consolidation or merger or which shall have received such assets shall be a
corporation organized and existing under the laws of the United States of
America or a state thereof and shall assume payment of the principal of (and
premium, if any) and interest on the Senior Debt Securities and the performance
and observance of all of the covenants and conditions of the Senior Indenture to
be performed or observed by the Company, and (ii) the Company or such successor
corporation, as the case may be, shall not immediately thereafter be in default
under the Senior Indenture.

MODIFICATION AND WAIVER

  Modification and amendment of the Indenture may be effected by the Company and
the Trustee with the consent of the Holders of 66 2/3% in principal amount of
the Outstanding Senior Debt Securities of each series issued pursuant to such
indenture and affected thereby, provided that no such modification or amendment
may, without the consent of the Holder of each Outstanding Senior Debt Security
affected thereby, (a) change the Stated Maturity of the principal of, or any
installment of interest or Additional Amounts payable on, any Senior Debt
Security or any premium payable on the redemption thereof, or change the
Redemption Price; (b) reduce the principal amount of, or the interest or
Additional Amounts payable on, any Senior Debt Security or reduce the amount of
principal which could be declared due and payable prior to the Stated Maturity;
(c) change place or currency of any payment of principal or any premium,
interest or Additional Amounts payable on any Senior Debt Security; (d) impair
the right to institute suit for the enforcement of any payment on or with
respect to any Senior Debt Security; (e) reduce the percentage in principal
amount of the Outstanding Senior Debt Securities of any series, the consent of
whose Holders is required to modify or amend the Indenture; or (f) modify the
foregoing requirements or reduce the percentage of Outstanding Senior Debt
Securities necessary to waive any past default to less than a majority.  No
modification or amendment of the Subordinated Indenture or any Subsequent
Indenture for Subordinated Debt Securities may adversely affect the rights of
any holder of Senior Indebtedness without the consent of such Holder.  Except
with respect to certain fundamental provisions, the Holders of at least a
majority in principal amount of Outstanding Senior Debt Securities of any series
may, with respect to such series, waive past defaults under the Indenture and
waive compliance by the Company with certain provisions thereof.

                                       13
<PAGE>
 
EVENTS OF DEFAULT

  Under the Senior Indenture, the following will be Events of Default with
respect to Senior Debt Securities of any series: (a) default in the payment of
any interest or Additional Amounts payable on any Senior Debt Security of that
series when due, continued for 30 days; (b) default in the payment of any
principal or premium, if any, on any Senior Debt Security of that series when
due; (c) default in the deposit of any sinking fund payment, when due, in
respect of any Senior Debt Security of that series; (d) default in the
performance of any other covenant of the Company contained in the Indenture for
the benefit of such series or in the Senior Debt Securities of such series,
continued for 60 days after written notice as provided in the Senior Indenture;
(e) certain events in bankruptcy, insolvency or reorganization; and (f) any
other Event of Default provided with respect to Senior Debt Securities of that
series.  The Trustee or the Holders of 25% in principal amount of the
Outstanding Senior Debt Securities of that series may declare the principal
amount (or such lesser amount as may be provided for in the Senior Debt
Securities of that series) of all Outstanding Senior Debt Securities of that
series and the interest due thereon and Additional Amounts payable in respect
thereof, if any to be due and payable immediately if an Event of Default with
respect to Senior Debt Securities of such series shall occur and be continuing
at the time of such declaration.  At any time after a declaration of
acceleration has been made with respect to Senior Debt Securities of any series
but before a judgment or decree for payment of money due has been obtained by
the Trustee, the Holders of a majority in principal amount of the Outstanding
Senior Debt Securities of that series may rescind any declaration of
acceleration and its consequences, if all payments due (other than those due as
a result of acceleration) have been made and all Events of Default have been
remedied or waived.  Any Event of Default with respect to Senior Debt Securities
of any series may be waived by the Holders of a majority in principal amount of
all Outstanding Senior Debt Securities of that series, except in a case of
failure to pay principal or premium, if any, or interest or Additional Amounts
payable on any Senior Debt Security of that series for which payment had not
been subsequently made or in respect of a covenant or provision which cannot be
modified or amended without the consent of the Holder of each Outstanding Senior
Debt Security of such series affected.

  The Holders of a majority in principal amount of the Outstanding Senior Debt
Securities of a series may 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 Senior Debt Securities of such
series, provided that such direction shall not be in conflict with any rule of
law or the Senior Indenture.  Before proceeding to exercise any right or power
under the Senior Indenture at the direction of such Holders, the Trustee shall
be entitled to receive from such Holders reasonable security or indemnity
against the costs, expenses and liabilities which might be incurred by it in
complying with any such direction.

  The Company is required to furnish to the Trustee annually a statement as to
the fulfillment by the Company of all of its obligations under the Senior
Indenture.

                           MERRILL LYNCH & CO., INC.
       S&P 500 MARKET INDEX TARGET-TERM SECURITIES(SM) DUE MAY 10, 2001
                                 ("MITTS(R)")

  On May 13, 1996, Merrill Lynch & Co., Inc. (the "Company") issued an aggregate
principal amount of $110,000,000 of S&P 500 Market Index Target-Term Securities
due May 10, 2001 (the "Securities" or "MITTS").  Each $10 principal amount of
Securities will be deemed a "Unit" for purposes of trading and transfer at the
Securities Depository described below.  Units will be transferable by the
Securities Depository, as more fully described below, in denominations of whole
Units.

  The Securities are debt securities of the Company. The Securities were issued
in denominations of $10 and integral multiples thereof, will bear no periodic
payments of interest and will mature on May 10, 2001. At maturity, a beneficial
owner of a Security will be entitled to receive, with respect to each Security,
the principal amount thereof plus an interest payment, if any (the "Supplemental
Redemption Amount"), based on the percentage increase, if any, in the S&P 500
Composite Stock Price Index (the "Index") over the Starting Index Value. The
Supplemental Redemption Amount will in no event be less than zero. The
Securities are not redeemable or callable by the Company prior to maturity. At
maturity, a beneficial owner of a Security will receive the principal amount of
such Security plus the Supplemental Redemption Amount, if any, however, there
will be no other payment of interest, periodic or otherwise.

  The Supplemental Redemption Amount payable with respect to a Security at
maturity will equal the product of (A) the principal amount of the applicable
Security, (B) the percentage increase from the Starting Index Value to the
Ending Index Value, and (C) the Participation Rate. The Starting Index Value
equals 638.26 which was the closing value of the Index on the date the
Securities were priced by the Company for initial sale to the public (the
"Pricing Date"). The Ending Index Value, as more particularly described herein,
will be the average (arithmetic mean) of the closing values of the Index on
certain days, or, if certain events occur, the closing value of the Index on a
single day prior to the maturity of the Securities. The Participation Rate
equals 110%.

  FOR INFORMATION AS TO THE CALCULATION OF THE SUPPLEMENTAL REDEMPTION AMOUNT

  For the purpose of calculating the ratio of earnings to fixed charges,
"earnings" consists of earnings from continuing operations before income taxes
and fixed charges.  "Fixed charges" consists of interest costs, amortization of
debt expense, preferred stock dividend requirements of majority-owned
subsidiaries, and that portion of rentals estimated to be representative of the
interest factor.


                                  RISK FACTORS
PAYMENT AT MATURITY

  Supplemental Redemption Amount May be Zero.   Investors should be aware that
if the Ending Index Value does not exceed the Starting Index Value, beneficial
owners of the Securities will receive only the principal amount thereof at
maturity, even if the value of the Index at some point between the issue date
and the maturity date of the Securities exceeded the Starting Index Value.

  Yield may be Below Market Interest Rates on the Pricing Date.   A beneficial
owner of the Securities may receive no Supplemental Redemption Amount at
maturity, or a Supplemental Redemption Amount that is below what the Company
would pay as interest as of the Pricing Date if the Company issued non-callable
senior debt securities with a similar maturity as that of the Securities. The
return of principal of the Securities at maturity and the payment of the
Supplemental Redemption Amount, if any, may not reflect the full opportunity
costs implied by inflation or other factors relating to the time value of money.

  Yield on Securities will not Reflect Dividends.   The Index does not reflect
the payment of dividends on the stocks underlying it and therefore the yield
based on the Index to the maturity of the Securities will not produce the same
yield as if such underlying stocks were purchased and held for a similar period.

  State Law Limit on Interest Paid.   Because the Senior Indenture provides that
the Securities are governed by and construed in accordance with the laws of New
York, certain usury laws of New York State may apply. Under present New York
law, the maximum rate of interest is 25% per annum on a simple interest basis.
This limit may not apply to Securities in which $2,500,000 or more has been
invested. While the Company believes that New York law would be given effect by
a state or Federal court sitting outside of New York, state laws frequently
regulate the amount of interest that may be charged to and paid by a borrower
(including, in some cases, corporate borrowers). It is suggested that
prospective investors consult their personal advisors with respect to the
applicability of such laws. The Company will covenant for the benefit of the
Holders of the Securities, to the extent permitted by law, not to claim
voluntarily the benefits of any laws concerning usurious rates of interest
against a Holder of the Securities.


TRADING

  The Securities have been listed on the New York Stock Exchange under the
symbol "MIX".

   It is expected that the trading value of the Securities in the secondary
market will be affected by the creditworthiness of the Company and by a number
of other factors. The trading value of the Securities is expected to depend
substantially on the extent of the appreciation, if any, of the Index over the
Starting Index Value. See "The Index--Historical Data on the Index" in this
Prospectus for historical values of the Index. If, however, Securities are sold
prior to the maturity date at a time when the Index exceeds the Starting Index
Value, the sale price may be at a substantial discount from the amount expected
to be payable to the beneficial owner if such excess of the Index over the
Starting Index Value were to prevail until maturity of the Securities because of
the possible fluctuation of the Index between the time of such sale and the time
that the Ending Index Value is determined. Furthermore, the price at which a
beneficial owner will be able to sell Securities prior to maturity may be at a

                                       4
<PAGE>
 
discount, which could be substantial, from the principal amount thereof, if, at
such time, the Index is below, equal to, or not sufficiently above the Starting
Index Value. A discount could also result from rising interest rates.

  In addition to the value of the Index, the trading value of the Securities may
be affected by a number of interrelated factors, including the creditworthiness
of the Company and those factors listed below. The relationship among these
factors is complex, including how these factors affect the relative value of the
principal amount of the Securities to be repaid at maturity and the value of the
Supplemental Redemption Amount, if any. Accordingly, investors should be aware
that factors other than the level of the Index are likely to affect the
Securities' trading value. The expected effect on the trading value of the
Securities of each of the factors listed below, assuming in each case that all
other factors are held constant, is as follows:

  Interest Rates.   Because the Securities repay at a minimum the principal
amount thereof at maturity, the trading value of the Securities will likely be
affected by changes in interest rates. In general, if U.S. interest rates
increase, the trading value of the Securities is expected to decrease. If U.S.
interest rates decrease, the trading value of the Securities is expected to
increase. Interest rates may also affect the U.S. economy, and, in turn, the
value of the Index. Rising interest rates may lower the value of the Index and,
thus, the Securities. Falling interest rates may increase the value of the Index
and, thus, may increase the value of the Securities.

  Volatility of the Index.   If the volatility of the Index increases, the
trading value of the Securities is expected to increase. If the volatility of
the Index decreases, the trading value of the Securities is expected to
decrease.

  Time Remaining to Maturity.   The Securities may trade at a value above that
which may be inferred from the level of interest rates and the Index. This
difference will reflect a "time premium" due to expectations concerning the
value of the Index during the period prior to maturity of the Securities. As the
time remaining to maturity of the Securities decreases, however, this time
premium is expected to decrease, thus decreasing the trading value of the
Securities. In addition, the price at which a beneficial owner may be able to
sell Securities prior to maturity may be at a discount, which may be
substantial, from the principal amount of the Securities if the value of the
Index is below, equal to, or not sufficiently above the Starting Index Value.

  Dividend Rates in the United States.   If dividend rates on the stocks
comprising the Index increase, the value of the Securities is expected to
decrease. Conversely, if dividend rates on the stocks comprising the Index
decrease, the value of the Securities is expected to increase. However, in
general, rising U.S. corporate dividend rates may increase the value of the
Index and, in turn, increase the value of the Securities. Conversely, falling
U.S. dividend rates may decrease the value of the Index and, in turn, decrease
the value of the Securities.

  The impact of the factors specified above, excluding the value of the Index,
may offset, partially or in whole, any increase in the trading value of the
Securities that is attributable to an increase in the value of the Index. For
example, an increase in U.S. interest rates may cause the Securities to trade at
a discount from their initial offering price, even if the Index has appreciated
significantly. In general, assuming all relevant factors are held constant, the
effect on the trading value of the Securities of a given change in interest
rates, Index volatility and/or dividend rates of stocks comprising the Index is
expected to be less if it occurs later in the term of the Securities than if it
occurs earlier in the term of the Securities. The effect on the trading value of
the Securities of a given appreciation of the Index in excess of the Starting
Index Value is expected to be greater if it occurs later in the term of the
Securities than if it occurs earlier in the term of the Securities, assuming all
other relevant factors are held constant.


THE INDEX

  The value of the Index and the Supplemental Redemption Amount, if any, may be
adversely affected by political, economic and other developments that affect the
stocks underlying the Index.

                                       5

OTHER CONSIDERATIONS

  It is suggested that prospective investors who consider purchasing the
Securities should reach an investment decision only after carefully considering
the suitability of the Securities in light of their particular circumstances.

  Investors should also consider the tax consequences of investing in the
Securities and should consult their tax advisors.

  MLPF&S or its affiliates may from time to time engage in transactions
involving the stocks underlying the Index for their proprietary accounts and for
other accounts under their management, which may influence the value of such
stocks and therefore the value of the Securities. MLPF&S and its affiliates will
also be the counterparties to the hedge of the Company's obligations under the
Securities.  Accordingly, under certain circumstances, conflicts of interest may
arise between MLPF&S's responsibilities as Calculation Agent with respect to the
Securities and its obligations under its hedge and its status as a subsidiary of
the Company. Under certain circumstances, the duties of MLPF&S as Calculation
Agent in determining the existence of Market Disruption Events could conflict
with the interests of MLPF&S as an affiliate of the issuer of the Securities,
Merrill Lynch & Co., Inc., and with the interests of the holders of the
Securities.


                           DESCRIPTION OF SECURITIES

GENERAL

  The Securities were issued as a series of Senior Debt Securities under the
Senior Indenture, referred to as the "Senior Indenture", which is more fully
described below. The Securities will mature on May 10, 2001.

  At maturity, a beneficial owner of a Security will receive the principal
amount of such Security plus the Supplemental Redemption Amount, if any,
however, there will be no other payment of interest, periodic or otherwise. (See
"Payment at Maturity" below.)

  The Securities are not subject to redemption by the Company or at the option
of any beneficial owner prior to maturity. Upon the occurrence of an Event of
Default with respect to the Securities, beneficial owners of the Securities may
accelerate the maturity of the Securities, as described under "Description of
Securities--Events of Default and Acceleration" in this Prospectus and "Other
Terms--Events of Default" in this Prospectus.

  The Securities were issued in denominations of whole Units.


PAYMENT AT MATURITY

  At maturity, a beneficial owner of a Security will be entitled to receive the
principal amount thereof plus a Supplemental Redemption Amount, if any, all as
provided below. If the Ending Index Value does not exceed the Starting Index
Value a beneficial owner of a Security will be entitled to receive only the
principal amount thereof.

  At maturity, a beneficial owner of a Security will be entitled to receive,
with respect to each such Security, (i) the principal amount thereof ($10 for
each Unit), and (ii) the Supplemental Redemption Amount equal in amount to:

<TABLE> 
<S>                  <C>                                       <C>
Principal Amount  X  Ending Index Value--Starting Index Value  X  Participation Rate
                     ----------------------------------------                  
                              Starting Index Value
</TABLE> 

                                       6
<PAGE>
 
provided, however, that in no event will the Supplemental Redemption Amount be
less than zero. The Starting Index Value equals 638.26, which was the closing
value of the Index on the date the Securities were priced by the Company for
initial sale to the public (i.e, the Pricing Date). The Participation Rate
equals 110%. The Ending Index Value will be determined by Merrill Lynch, Pierce,
Fenner & Smith Incorporated (the "Calculation Agent") and will equal the average
(arithmetic mean) of the closing values of the Index determined on each of the
first five Calculation Days during the Calculation Period. If there are fewer
than five Calculation Days, then the Ending Index Value will equal the average
(arithmetic mean) of the closing values of the Index on such Calculation Days,
and if there is only one Calculation Day, then the Ending Index Value will equal
the closing value of the Index on such Calculation Day. If no Calculation Days
occur during the Calculation Period because of Market Disruption Events, then
the Ending Index Value will equal the closing value of the Index determined on
the last scheduled Index Business Day in the Calculation Period, regardless of
the occurrences of a Market Disruption Event on such day. The "Calculation
Period" means the period from and including the seventh scheduled Index Business
Day prior to the maturity date to and including the second scheduled Index
Business Day prior to the maturity date. "Calculation Day" means any Index
Business Day during the Calculation Period on which a Market Disruption Event
has not occurred. For purposes of determining the Ending Index Value, an "Index
Business Day" is a day on which the New York Stock Exchange and the American
Stock Exchange are open for trading and the Index or any Successor Index is
calculated and published. All determinations made by the Calculation Agent shall
be at the sole discretion of the Calculation Agent and, absent a determination
by the Calculation Agent of a manifest error, shall be conclusive for all
purpose and binding on the Company and beneficial owners of the Securities.

  The following table illustrates, for a range of hypothetical Ending Index
Values, (i) the total amount payable at maturity for each $10 principal amount
of Securities, (ii) the total rate of return to beneficial owners of the
Securities, (iii) the pretax annualized rate of return to beneficial owners of
Securities, and (iv) the pretax annualized rate of return of an investment in
the stocks underlying the Index (which includes an assumed aggregate dividend
yield of 2.20% per annum, as more fully described below).

(1) The annualized rates of return specified in the preceding table are
    calculated on a semiannual bond equivalent basis.

(2) This rate of return assumes (i) an investment of a fixed amount in the
    stocks underlying the Index with the allocation of such amount reflecting
    the current relative weights of such stocks in the Index; (ii) a percentage
    change in the aggregate price of such stocks that equals the percentage
    change in the Index from the Starting Index Value to the relevant
    hypothetical Ending Index Value; (iii) a constant dividend yield of 2.20%
    per annum, paid quarterly from the date of initial delivery of Securities,
    applied to the value of the Index at the end of each such quarter assuming
    such value increases or decreases linearly from the Starting Index Value to
    the applicable hypothetical Ending Index

    Value; (iv) no transaction fees or expenses; (v) a term for the Securities
    from May 13, 1996 to May 10, 2001; and (vi) a final Index value equal to the
    Ending Index Value. The aggregate dividend yield of the stocks underlying
    the Index as of May 7, 1996 was approximately 2.20%.

(3)  The Starting Index Value.

  The above figures are for purposes of illustration only. The actual
Supplemental Redemption Amount received by investors and the total and pretax
annualized rate of return resulting therefrom will depend entirely on the actual
Ending Index Value determined by the Calculation Agent as provided herein.
Historical data regarding the Index is included in this Prospectus under "The
Index--Historical Data on the Index".


ADJUSTMENTS TO THE INDEX; MARKET DISRUPTION EVENTS

  If at any time the method of calculating the Index, or the value thereof, is
changed in any material respect, or if the Index is in any other way modified so
that such Index does not, in the opinion of the Calculation Agent, fairly
represent the value of the Index had such changes or modifications not been
made, then, from and after such time, the Calculation Agent shall, at the close
of business in New York, New York, on each date that the closing value with
respect to the Ending Index Value is to be calculated, make such adjustments as,
in the good faith judgment of the Calculation Agent, may be necessary in order
to arrive at a calculation of a value of a stock index comparable to the Index
as if such changes or modifications had not been made, and calculate such
closing value with reference to the Index, as adjusted. Accordingly, if the
method of calculating the Index is modified so that the value of such Index is a
fraction or a multiple of what it would have been if it had not been modified
(e.g., due to a split in the Index), then the Calculation Agent shall adjust
such Index in order to arrive at a value of the Index as if it had not been
modified (e.g., as if such split had not occurred).

  "Market Disruption Event" means either of the following events, as determined
by the Calculation Agent:

  (i) the suspension or material limitation (limitations pursuant to New York
Stock Exchange Rule 80A (or any applicable rule or regulation enacted or
promulgated by the New York Stock Exchange or any other self regulatory
organization or the Securities and Exchange Commission of similar scope as
determined by the Calculation Agent) on trading during significant market
fluctuations shall be considered "material" for purposes of this definition), in
each case, for more than two hours of trading in 100 or more of the securities
included in the S&P 500 Index, or

  (ii) the suspension or material limitation, in each case, for more than two
hours of trading (whether by reason of movements in price otherwise exceeding
levels permitted by the relevant exchange or otherwise) in (A) futures contracts
related to the Index which are traded on the Chicago Mercantile Exchange or (B)
option contracts related to the Index which are traded on the Chicago Board
Options Exchange, Inc.

  For the purposes of this definition, a limitation on the hours in a trading
day and/or number of days of trading will not constitute a Market Disruption
Event if it results from an announced change in the regular business hours of
the relevant exchange.


DISCONTINUANCE OF THE INDEX

  If S&P discontinues publication of the Index and S&P or another entity
publishes a successor or substitute index that the Calculation Agent determines,
in its sole discretion, to be comparable to such Index (any such index being
referred to hereinafter as a "Successor Index"), then, upon the Calculation
Agent's notification of such determination to the Trustee and the Company, the
Calculation Agent will substitute the Successor Index as calculated by S&P or
such other entity for the Index and calculate the Ending Index Value as
described above under "Payment at Maturity". Upon any selection by the
Calculation Agent of a Successor Index, the Company shall cause notice thereof
to be given to Holders of the Securities.

                                       8
<PAGE>
 
  If S&P discontinues publication of the Index and a Successor Index is not
selected by the Calculation Agent or is no longer published on any of the
Calculation Days, the value to be substituted for the Index for any such
Calculation Day used to calculate the Supplemental Redemption Amount at maturity
will be a value computed by the Calculation Agent for each Calculation Day in
accordance with the procedures last used to calculate the Index prior to any
such discontinuance. If a Successor Index is selected or the Calculation Agent
calculates a value as a substitute for the Index as described below, such
Successor Index or value shall be substituted for the Index for all purposes,
including for purposes of determining whether a Market Disruption Event exists.

  If S&P discontinues publication of the Index prior to the period during which
the Supplemental Redemption Amount is to be determined and the Calculation Agent
determines that no Successor Index is available at such time, then on each
Business Day until the earlier to occur of (i) the determination of the Ending
Index Value and (ii) a determination by the Calculation Agent that a Successor
Index is available, the Calculation Agent shall determine the value that would
be used in computing the Supplemental Redemption Amount as described in the
preceding paragraph as if such day were a Calculation Day. The Calculation Agent
will cause notice of each such value to be published not less often than once
each month in The Wall Street Journal (or another newspaper of general
circulation), and arrange for information with respect to such values to be made
available by telephone. Notwithstanding these alternative arrangements,
discontinuance of the publication of the Index may adversely affect trading in
the Securities.


EVENTS OF DEFAULT AND ACCELERATION

  In case an Event of Default with respect to any Securities shall have occurred
and be continuing, the amount payable to a beneficial owner of a Security upon
any acceleration permitted by the Securities, with respect to each $10 principal
amount thereof, will be equal to: (i) the initial issue price ($10), plus (ii)
an additional amount of contingent interest calculated as though the date of
early repayment were the maturity date of the Securities. See "Description of
Securities--Payment at Maturity" in this Prospectus. If a bankruptcy proceeding
is commenced in respect of the Company, the claim of the beneficial owner of a
Security may be limited, under Section 502(b)(2) of Title 11 of the United
States Code, to the principal amount of the Security plus an additional amount
of contingent interest calculated as though the date of the commencement of the
proceeding were the maturity date of the Securities.

  In case of default in payment at the maturity date of the Securities (whether
at their stated maturity or upon acceleration), from and after the maturity date
the Securities shall bear interest, payable upon demand of the beneficial owners
thereof, at the rate of 8% per annum (to the extent that payment of such
interest shall be legally enforceable) on the unpaid amount due and payable on
such date in accordance with the terms of the Securities to the date payment of
such amount has been made or duly provided for.


DEPOSITORY

  The issuance, all Securities are represented by one or more fully registered
global securities (the "Global Securities"). Each such Global Security has been
deposited with, or on behalf of, The Depository Trust Company ("DTC"), as
Depository (the "Depository"), registered in the name of DTC or a nominee
thereof. Unless and until it is exchanged in whole or in part for Securities in
definitive form, no Global Security may be transferred except as a whole by the
Depository to a nominee of such Depository or by a nominee of such Depository to
such Depository or another nominee of such Depository or by such Depository or
any such nominee to a successor of such Depository or a nominee of such
successor.

  DTC has advised the Company as follows: DTC is a limited-purpose trust company
organized under the Banking Law of the State of New York, a member of the
Federal Reserve System, a "clearing corporation" within the meaning of the New
York Uniform Commercial Code, and a "clearing agency" registered pursuant to the
provisions

                                       9
<PAGE>
 
of Section 17A of the Exchange Act. DTC was created to hold securities of its
participants ("Participants") and to facilitate the clearance and settlement of
securities transactions among its Participants in such securities through
electronic book-entry changes in accounts of the Participants, thereby
eliminating the need for physical movement of securities certificates. DTC's
Participants include securities brokers and dealers, banks, trust companies,
clearing corporations, and certain other organizations.

  DTC is owned by a number of Participants and by the New York Stock Exchange,
Inc., the American Stock Exchange, Inc. and the National Association of
Securities Dealers, Inc. Access to the DTC book-entry system is also available
to others, such as banks, brokers, dealers and trust companies that clear
through or maintain a custodial relationship with a Participant, either directly
or indirectly ("Indirect Participants").

  Purchases of Securities must be made by or through Participants, which will
receive a credit on the records of DTC. The ownership interest of each actual
purchaser of each Security ("Beneficial Owner") is in turn to be recorded on the
Participants' or Indirect Participants' records. Beneficial Owners will not
receive written confirmation from DTC of their purchase, but Beneficial Owners
are expected to receive written confirmations providing details of the
transaction, as well as periodic statements of their holdings, from the
Participant or Indirect Participant through which the Beneficial Owner entered
into the transaction. Ownership of beneficial interests in such Global Security
will be shown on, and the transfer of such ownership interests will be effected
only through, records maintained by DTC (with respect to interests of
Participants) and on the records of Participants (with respect to interests of
persons held through Participants). The laws of some states may require that
certain purchasers of securities take physical delivery of such securities in
definitive form. Such limits and such laws may impair the ability to own,
transfer or pledge beneficial interests in Global Securities.

  So long as DTC, or its nominee, is the registered owner of a Global Security,
DTC or its nominee, as the case may be, will be considered the sole owner or
Holder of the Securities represented by such Global Security for all purposes
under the Senior Indenture. Except as provided below, Beneficial Owners in a
Global Security will not be entitled to have the Securities represented by such
Global Securities registered in their names, will not receive or be entitled to
receive physical delivery of the Securities in definitive form and will not be
considered the owners or Holders thereof under the Senior Indenture, including
for purposes of receiving any reports delivered by the Company or the Trustee
pursuant to the Senior Indenture. Accordingly, each Person owning a beneficial
interest in a Global Security must rely on the procedures of DTC and, if such
Person is not a Participant, on the procedures of the Participant through which
such Person owns its interest, to exercise any rights of a Holder under the
Senior Indenture. The Company understands that under existing industry
practices, in the event that the Company requests any action of Holders or that
an owner of a beneficial interest in such a Global Security desires to give or
take any action which a Holder is entitled to give or take under the Senior
Indenture, DTC would authorize the Participants holding the relevant beneficial
interests to give or take such action, and such Participants would authorize
Beneficial Owners owning through such Participants to give or take such action
or would otherwise act upon the instructions of Beneficial Owners. Conveyance of
notices and other communications by DTC to Participants, by Participants to
Indirect Participants, and by Participants and Indirect Participants to
Beneficial Owners will be governed by arrangements among them, subject to any
statutory or regulatory requirements as may be in effect from time to time.

  Payment of the principal of, and any Supplemental Redemption Amount with
respect to, Securities registered in the name of DTC or its nominee will be made
to DTC or its nominee, as the case may be, as the Holder of the Global
Securities representing such Securities. None of the Company, the Trustee or any
other agent of the Company or agent of the Trustee will have any responsibility
or liability for any aspect of the records relating to or payments made on
account of beneficial ownership interests or for supervising or reviewing any
records relating to such beneficial ownership interests. The Company expects
that DTC, upon receipt of any payment of principal or any Supplemental
Redemption Amount in respect of a Global Security, will credit the accounts of
the Participants with payment in amounts proportionate to their respective
holdings in principal amount of beneficial interest in such Global Security as
shown on the records of DTC. The Company also expects that payments by
Participants to Beneficial Owners will be governed by standing customer
instructions and customary practices, as is now the case

                                       10
<PAGE>
 
with securities held for the accounts of customers in bearer form or registered
in "street name", and will be the responsibility of such Participants.

  If (x) any Depository is at any time unwilling or unable to continue as
Depository and a successor depository is not appointed by the Company within 60
days, (y) the Company executes and delivers to the Trustee a Company Order to
the effect that the Global Securities shall be exchangeable or (z) an Event of
Default has occurred and is continuing with respect to the Securities, the
Global Securities will be exchangeable for Securities in definitive form of like
tenor and of an equal aggregate principal amount, in denominations of $1,000 and
integral multiples thereof. Such definitive Securities shall be registered in
such name or names as the Depository shall instruct the Trustee. It is expected
that such instructions may be based upon directions received by the Depository
from Participants with respect to ownership of beneficial interests in such
Global Securities.


SAME-DAY SETTLEMENT AND PAYMENT

  Settlement for the Securities will be made by the Underwriter in immediately
available funds. All payments of principal and the Supplemental Redemption
Amount, if any, will be made by the Company in immediately available funds so
long as the Securities are maintained in book-entry form.


                                   THE INDEX

  All disclosure contained in this Prospectus regarding the Index, including,
without limitation, its make-up, method of calculation and changes in its
components, is derived from publicly available information prepared by S&P as of
May 7, 1996. Neither the Company nor the Underwriter takes any responsibility
for the accuracy or completeness of such information.


GENERAL

  The Index is published by S&P and is intended to provide an indication of the
pattern of common stock price movement. The calculation of the value of the
Index (discussed below in further detail) is based on the relative value of the
aggregate Market Value (as defined below) of the common stocks of 500 companies
as of a particular time as compared to the aggregate average Market Value of the
common stocks of 500 similar companies during the base period of the years 1941
through 1943. As of April 29, 1996, the 500 companies included in the Index
represented approximately 77% of the aggregate Market Value of common stocks
traded on The New York Stock Exchange; however, these 500 companies are not the
500 largest companies listed on The New York Stock Exchange and not all of these
500 companies are listed on such exchange. As of April 29, 1996, the aggregate
market value of the 500 companies included in the Index represented
approximately 70% of the aggregate market value of United States domestic,
public companies. S&P chooses companies for inclusion in the Index with the aim
of achieving a distribution by broad industry groupings that approximates the
distribution of these groupings in the common stock population of The New York
Stock Exchange, which S&P uses as an assumed model for the composition of the
total market. Relevant criteria employed by S&P include the viability of the
particular company, the extent to which that company represents the industry
group to which it is assigned, the extent to which the market price of that
Company's common stock is generally responsive to changes in the affairs of the
respective industry and the Market Value and trading activity of the common
stock of that company. As of April 29, 1996, the 500 companies included in the
Index were divided into 90 individual groups. These individual groups comprised
the following four main groups of companies (with the number of companies
currently included in each group indicated in parentheses): Industrials (372),
Utilities (49), Transportation (14) and Financial (65). S&P may from time to
time, in its sole discretion, add companies to, or delete companies from, the
Index to achieve the objectives stated above.

                                       11
<PAGE>
 
COMPUTATION OF THE S&P 500 INDEX

  S&P currently computes the Index as of a particular time as follows:

  (1) the product of the market price per share and the number of then
outstanding shares of each component stock is determined as of such time (such
product referred to as the "Market Value" of such stock);

  (2) the Market Value of all component stocks as of such time (as determined
under clause (1) above) are aggregated;

  (3) the mean average of the Market Values as of each week in the base period
of the years 1941 through 1943 of the common stock of each company in a group of
500 substantially similar companies is determined;

  (4) the mean average Market Values of all such common stocks over such base
period (as determined under clause (3) above) are aggregated (such aggregate
amount being referred to as the "Base Value");

  (5) the aggregate Market Value of all component stocks as of such time (as
determined under clause (2) above) is divided by the Base Value; and
  (6) the resulting quotient (expressed in decimals) is multiplied by ten.

While S&P currently employs the above methodology to calculate the Index, no
assurance can be given that S&P will not modify or change such methodology in a
manner that may affect the Supplemental Redemption Amount, if any, payable to
beneficial owners of Securities upon maturity or otherwise.

  S&P adjusts the foregoing formula to negate the effect of changes in the
Market Value of a component stock that are determined by S&P to be arbitrary or
not due to true market fluctuations. Such changes may result from such causes as
the issuance of stock dividends, the granting to shareholders of rights to
purchase additional shares of such stock, the purchase thereof by employees
pursuant to employee benefit plans, certain consolidations and acquisitions, the
granting to shareholders of rights to purchase other securities of the company,
the substitution by S&P of particular component stocks in the Index, and other
reasons. In all such cases, S&P first recalculates the aggregate Market Value of
all component stocks (after taking account of the new market price per share of
the particular component stock or the new number of outstanding shares thereof
or both, as the case may be) and then determines the New Base Value in
accordance with the following formula:

               Old Base Value  X  New Market Value   = New Base Value
                                  -----------------                  
                                  Old Market Value


The result is that the Base Value is adjusted in proportion to any change in the
aggregate Market Value of all component stocks resulting from the causes
referred to above to the extent necessary to negate the effects of such causes
upon the Index.

   A potential investor should review the historical performance of the Index.
The historical performance of the Index should not be taken as an indication of
future performance, and no assurance can be given that the Index will increase
sufficiently to cause the beneficial owners of the Securities to receive an
amount in excess of the principal amount at the maturity of the Securities.

LICENSE AGREEMENT

  S&P and Merrill Lynch Capital Services, Inc. have entered into a non-exclusive
license agreement providing for the license to Merrill Lynch Capital Services,
Inc., in exchange for a fee, of the right to use indices owned and published by
S&P in connection with certain securities, including the Securities, and the
Company is an authorized sublicensee thereof.

  The license agreement between S&P and Merrill Lynch Capital Services, Inc.
provides that the following language must be stated in this Prospectus:

                                       12
<PAGE>
 
     "The Securities are not sponsored, endorsed, sold or promoted by S&P. S&P
  makes no representation or warranty, express or implied, to the Holders of the
  Securities or any member of the public regarding the advisability of investing
  in securities generally or in the Securities particularly or the ability of
  the Index to track general stock market performance. S&P's only relationship
  to Merrill Lynch Capital Services, Inc. and the Company (other than
  transactions entered into in the ordinary course of business) is the licensing
  of certain servicemarks and trade names of S&P and of the Index which is
  determined, composed and calculated by S&P without regard to the Company or
  the Securities. S&P has no obligation to take the needs of the Company or the
  Holders of the Securities into consideration in determining, composing or
  calculating the Index. S&P is not responsible for and has not participated in
  the determination of the timing of the sale of the Securities, prices at which
  the Securities are to initially be sold, or quantities of the Securities to be
  issued or in the determination or calculation of the equation by which the
  Securities are to be converted into cash. S&P has no obligation or liability
  in connection with the administration, marketing or trading of the
  Securities."


                                  OTHER TERMS
GENERAL

  The Securities were issued as a series of Senior Debt Securities under the
Indenture (the "Senior Indenture"), dated as of April 1, 1983, as amended and
restated, between the Company and The Chase Manhattan Bank, formerly known as
Chemical Bank (successor by merger to Manufacturers Hanover Trust Company), as
trustee (the "Trustee"). A copy of the Senior Indenture is filed as an exhibit
to the registration statements relating to the Securities. The following
summaries of certain provisions of the Senior Indenture do not purport to be
complete and are subject to, and qualified in their entirety by reference to,
all provisions of the Senior Indenture, including the definition therein of
certain terms.

  The Senior Indenture provides that series of Senior Debt Securities may from
time to time be issued thereunder, without limitation as to aggregate principal
amount, in one or more series and upon such terms as the Company may establish
pursuant to the provisions thereof.

  The Senior Indenture provides that the Senior Indenture and the Securities are
governed by and construed in accordance with the laws of the State of New York.

  The Senior Indenture provides that the Company may issue Senior Debt
Securities with terms different from those of Senior Debt Securities previously
issued, and "reopen" a previously issued series of Senior Debt Securities and
issue additional Senior Debt Securities of such series.

  The Senior Debt Securities are unsecured and rank pari passu with all other
unsecured and unsubordinated indebtedness of the Company.  However, since the
Company is a holding company, the right of the Company, and hence the right of
creditors of the Company (including the Holders of Senior Debt Securities), to
participate in any distribution of the assets of any subsidiary upon its
liquidation or reorganization or otherwise is necessarily subject to the prior
claims of creditors of the subsidiary, except to the extent that claims of the
Company itself as a creditor of the subsidiary may be recognized.  In addition,
dividends, loans and advances from certain subsidiaries, including MLPF&S, to
the Company are restricted by net capital requirements under the Exchange Act
and under rules of certain exchanges and other regulatory bodies.


LIMITATIONS UPON LIENS

  The Company may not, and may not permit any Subsidiary to, create, assume,
incur or permit to exist any indebtedness for borrowed money secured by a
pledge, lien or other encumbrance (except for certain liens specifically
permitted by the Senior Indenture) on the Voting Stock owned directly or
indirectly by the Company of any Subsidiary (other than a Subsidiary which, at
the time of the incurrence of such secured indebtedness, has a net worth

                                       13
<PAGE>
 
of less than $3,000,000) without making effective provision whereby the
Outstanding Senior Debt Securities will be secured equally and ratably with such
secured indebtedness.


LIMITATION ON DISPOSITION OF VOTING STOCK OF, AND MERGER AND SALE OF ASSETS BY,
MLPF&S

  The Indenture provides that the Company may not sell, transfer or otherwise
dispose of any Voting Stock of MLPF&S or permit MLPF&S to issue, sell or
otherwise dispose of any of its Voting Stock, unless, after giving effect to any
such transaction, MLPF&S remains a Controlled Subsidiary (defined in the Senior
Indenture to mean a corporation more than 80% of the outstanding shares of
Voting Stock of which are owned directly or indirectly by the Company).  In
addition, the Company may not permit MLPF&S to (i) merge or consolidate, unless
the surviving company is a Controlled Subsidiary or (ii) convey or transfer its
properties and assets substantially as an entirety, except to one or more
Controlled Subsidiaries.


MERGER AND CONSOLIDATION

  The Indenture provides that the Company may consolidate or merge with or into
any other corporation, and the Company may sell, lease or convey all or
substantially all of its assets to any corporation, provided that (i) the
corporation (if other than the Company) formed by or resulting from any such
consolidation or merger or which shall have received such assets shall be a
corporation organized and existing under the laws of the United States of
America or a state thereof and shall assume payment of the principal of (and
premium, if any) and interest on the Senior Debt Securities and the performance
and observance of all of the covenants and conditions of the Senior Indenture to
be performed or observed by the Company, and (ii) the Company or such successor
corporation, as the case may be, shall not immediately thereafter be in default
under the Senior Indenture.


MODIFICATION AND WAIVER

  Modification and amendment of the Indenture may be effected by the Company and
the Trustee with the consent of the Holders of 66 2/3% in principal amount of
the Outstanding Senior Debt Securities of each series issued pursuant to such
indenture and affected thereby, provided that no such modification or amendment
may, without the consent of the Holder of each Outstanding Senior Debt Security
affected thereby, (a) change the Stated Maturity of the principal of, or any
installment of interest or Additional Amounts payable on, any Senior Debt
Security or any premium payable on the redemption thereof, or change the
Redemption Price; (b) reduce the principal amount of, or the interest or
Additional Amounts payable on, any Senior Debt Security or reduce the amount of
principal which could be declared due and payable prior to the Stated Maturity;
(c) change place or currency of any payment of principal or any premium,
interest or Additional Amounts payable on any Senior Debt Security; (d) impair
the right to institute suit for the enforcement of any payment on or with
respect to any Senior Debt Security; (e) reduce the percentage in principal
amount of the Outstanding Senior Debt Securities of any series, the consent of
whose Holders is required to modify or amend the Indenture; or (f) modify the
foregoing requirements or reduce the percentage of Outstanding Senior Debt
Securities necessary to waive any past default to less than a majority.  No
modification or amendment of the Subordinated Indenture or any Subsequent
Indenture for Subordinated Debt Securities may adversely affect the rights of
any holder of Senior Indebtedness without the consent of such Holder.  Except
with respect to certain fundamental provisions, the Holders of at least a
majority in principal amount of Outstanding Senior Debt Securities of any series
may, with respect to such series, waive past defaults under the Indenture and
waive compliance by the Company with certain provisions thereof.

                                       14
<PAGE>
 
EVENTS OF DEFAULT

  Under the Senior Indenture, the following will be Events of Default with
respect to Senior Debt Securities of any series: (a) default in the payment of
any interest or Additional Amounts payable on any Senior Debt Security of that
series when due, continued for 30 days; (b) default in the payment of any
principal or premium, if any, on any Senior Debt Security of that series when
due; (c) default in the deposit of any sinking fund payment, when due, in
respect of any Senior Debt Security of that series; (d) default in the
performance of any other covenant of the Company contained in the Indenture for
the benefit of such series or in the Senior Debt Securities of such series,
continued for 60 days after written notice as provided in the Senior Indenture;
(e) certain events in bankruptcy, insolvency or reorganization; and (f) any
other Event of Default provided with respect to Senior Debt Securities of that
series.  The Trustee or the Holders of 25% in principal amount of the
Outstanding Senior Debt Securities of that series may declare the principal
amount (or such lesser amount as may be provided for in the Senior Debt
Securities of that series) of all Outstanding Senior Debt Securities of that
series and the interest due thereon and Additional Amounts payable in respect
thereof, if any to be due and payable immediately if an Event of Default with
respect to Senior Debt Securities of such series shall occur and be continuing
at the time of such declaration.  At any time after a declaration of
acceleration has been made with respect to Senior Debt Securities of any series
but before a judgment or decree for payment of money due has been obtained by
the Trustee, the Holders of a majority in principal amount of the Outstanding
Senior Debt Securities of that series may rescind any declaration of
acceleration and its consequences, if all payments due (other than those due as
a result of acceleration) have been made and all Events of Default have been
remedied or waived.  Any Event of Default with respect to Senior Debt Securities
of any series may be waived by the Holders of a majority in principal amount of
all Outstanding Senior Debt Securities of that series, except in a case of
failure to pay principal or premium, if any, or interest or Additional Amounts
payable on any Senior Debt Security of that series for which payment had not
been subsequently made or in respect of a covenant or provision which cannot be
modified or amended without the consent of the Holder of each Outstanding Senior
Debt Security of such series affected.

  The Holders of a majority in principal amount of the Outstanding Senior Debt
Securities of a series may 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 Senior Debt Securities of such
series, provided that such direction shall not be in conflict with any rule of
law or the Senior Indenture.  Before proceeding to exercise any right or power
under the Senior Indenture at the direction of such Holders, the Trustee shall
be entitled to receive from such Holders reasonable security or indemnity
against the costs, expenses and liabilities which might be incurred by it in
complying with any such direction.

  The Company is required to furnish to the Trustee annually a statement as to
the fulfillment by the Company of all of its obligations under the Senior
Indenture.

                           MERRILL LYNCH & CO., INC.
      TECHNOLOGY MARKET INDEX TARGET-TERM SECURITIES(SM) DUE AUGUST 15, 2001
                                  ("MITTS(R)")

  On August 12, 1996, Merrill Lynch & Co., Inc. (the "Company") issued
$25,000,000 aggregate principal amount (2,500,000 Units) of Technology Market
Index Target-Term Securities due August 15, 2001 (the "Securities" or "MITTS").
Each $10 principal amount of Securities will be deemed a "Unit" for purposes of
trading and transfer at the Depository described below.  Units will be
transferable by the Depository, as more fully described below, in denominations
of whole Units.

  The Securities are debt securities of the Company, which were issued in
denominations of $10 and integral multiples thereof, will bear no periodic
payments of interest and will mature on August 15, 2001. At maturity, a
beneficial owner of a Security will be entitled to receive, with respect to each
Security, the principal amount thereof plus an interest payment (the
"Supplemental Redemption Amount"), based on the percentage increase, if any, in
the CBOE Technology Index* (the "Index") over the Benchmark Index Value.  The
Supplemental Redemption Amount will in no event be less than zero or more than
$10 per $10 principal amount of Securities, representing a maximum annualized
rate of return of 14.33% compounded semi-annually over the term of the
Securities. The Securities are not redeemable or callable by the Company prior
to maturity. At maturity, a beneficial owner of a Security will receive the
principal amount of such Security plus the Supplemental Redemption Amount, if
any, however, there will be no other payment of interest, periodic or otherwise.

  The Supplemental Redemption Amount payable with respect to a Security at
maturity will equal the product of (A) the principal amount of the applicable
Security and (B) the percentage increase from the Benchmark Index Value to the
Ending Index Value.  The Benchmark Index Value equals 189.48 and was determined
as described herein.  The closing value of the Index on the date the Securities
were priced by the Company for initial sale to the public was 168.43, and the
Benchmark Index Value exceeded such closing value by 12.5%.  The Ending Index
Value, as more particularly described herein, will be the average (arithmetic
mean) of the closing values of the Index on certain days, or, if certain events
occur, the closing value of the Index on a single day prior to the maturity of
the Securities.

  FOR INFORMATION AS TO THE CALCULATION OF THE SUPPLEMENTAL REDEMPTION AMOUNT
WHICH WILL BE PAID AT MATURITY, THE CALCULATION AND THE COMPOSITION OF THE
INDEX, SEE "DESCRIPTION OF SECURITIES" AND "THE INDEX", RESPECTIVELY, IN THIS
PROSPECTUS. FOR OTHER INFORMATION THAT SHOULD BE CONSIDERED BY PROSPECTIVE
INVESTORS, SEE "RISK FACTORS" BEGINNING ON PAGE 3 OF THIS PROSPECTUS.

  Ownership of the Securities will be maintained in book-entry form by or
through the Depository. Beneficial owners of the Securities will not have the
right to receive physical certificates evidencing their ownership except under
the limited circumstances described herein.

  The Securities have been listed on the Chicago Board Options Exchange, Inc.
(the "CBOE") and the New York Stock Exchange (the "NYSE") under the symbol
"TKM".

debt expense, preferred stock dividend requirements of majority-owned
subsidiaries, and that portion of rentals estimated to be representative of the
interest factor.


                                  RISK FACTORS
PAYMENT AT MATURITY

  Benchmark Index Value will Exceed Value of Index on the Pricing Date.   The
Benchmark Index Value exceeded the closing value of the Index on the Pricing
Date by 12.5%. Investors should be aware that if, at maturity, the Ending Index
Value does not exceed the closing Index value on the Pricing Date by more than
12.5%, beneficial owners of the Securities will receive only the principal
amount thereof.

                                       3
<PAGE>
 
  Yield may be Below Market Interest Rates on the Pricing Date.   A beneficial
owner of the Securities may receive no Supplemental Redemption Amount at
maturity, or a Supplemental Redemption Amount that is below what the Company
would pay as interest as of the Pricing Date if the Company issued non-callable
senior debt securities with a similar maturity as that of the Securities. The
return of principal of the Securities at maturity and the payment of the
Supplemental Redemption Amount, if any, may not reflect the full opportunity
costs implied by inflation or other factors relating to the time value of money.

  Limitation of Supplemental Redemption Amount.   Because the Supplemental
Redemption Amount will not exceed $10 per $10 principal amount of Securities,
beneficial owners of Securities will not benefit from Index increases in excess
of approximately 125% of the closing Index value on the Pricing Date (the
"Maximum Index Value"). In no event will the Supplemental Redemption Amount
exceed $10 per $10 principal amount of Securities.

  Yield on Securities will not Reflect Dividends.   The Index does not reflect
the payment of dividends on the stocks underlying it and therefore the yield
based on the Index to the maturity of the Securities will not produce the same
yield as if such underlying stocks were purchased and held for a similar period.

TRADING

  The Securities have been listed on the CBOE and on the NYSE under the symbol
"TKM".  It is expected that the secondary market for the Securities will be
affected by the creditworthiness of the Company and by a number of other
factors.

  The trading value of the Securities is expected to depend substantially on the
extent of the appreciation, if any, of the Index over the Benchmark Index Value.
If, however, Securities are sold prior to the maturity date at a time when the
Index exceeds the Benchmark Index Value, the sale price may be at a substantial
discount from the amount expected to be payable to the beneficial owner if such
excess of the Index over the Benchmark Index Value were to prevail until
maturity of the Securities because of the possible fluctuation of the Index
between the time of such sale and the time that the Ending Index Value is
determined. Furthermore, the price at which a beneficial owner will be able to
sell Securities prior to maturity may be at a discount, which could be
substantial, from the principal amount thereof, if, at such time, the Index is
below, equal to, or not sufficiently above the Benchmark Index Value. The
limitation that the Supplemental Redemption Amount will not exceed $10 per $10
principal amount of Securities may adversely affect the secondary market value
of the Securities and such adverse effect could occur even if the value of the
Index is below the Maximum Index Value. A discount could also result from rising
interest rates.

  In addition to the value of the Index, the trading value of the Securities may
be affected by a number of interrelated factors, including the creditworthiness
of the Company and those factors listed below. The relationship among these
factors is complex, including how these factors affect the relative value of the
principal amount of the Securities to be repaid at maturity and the value of the
Supplemental Redemption Amount. Accordingly, investors should be aware that
factors other than the level of the Index are likely to affect the Securities'
trading value. The expected effect on the trading value of the Securities of
each of the factors listed below, assuming in each case that all other factors
are held constant, is as follows:

  Interest Rates.   Because the Securities repay at a minimum the principal
amount thereof at maturity, the trading value of the Securities will likely be
affected by changes in interest rates. In general, if U.S. interest rates
increase, the trading value of the Securities is expected to decrease. If U.S.
interest rates decrease, the trading value of the Securities is expected to
increase. Interest rates may also affect the U.S. economy, and, in turn, the
value of the Index. Rising interest rates may lower the value of the Index and,
thus, may decrease the trading value of the Securities. Falling interest rates
may increase the value of the Index and, thus, may increase the trading value of
the Securities.

                                       4
<PAGE>
 
  Volatility of the Index.   If the volatility of the Index increases, the
trading value of the Securities is expected to increase. If the volatility of
the Index decreases, the trading value of the Securities is expected to
decrease.

  Time Remaining to Maturity.   The Securities may trade at a value above that
which may be inferred from the level of interest rates and the Index. This
difference will reflect a "time premium" due to expectations concerning the
value of the Index during the period prior to maturity of the Securities. As the
time remaining to maturity of the Securities decreases, however, this time
premium is expected to decrease, thus decreasing the trading value of the
Securities. In addition, the price at which a beneficial owner may be able to
sell Securities prior to maturity may be at a discount, which may be
substantial, from the principal amount of the Securities if the value of the
Index is below, equal to, or not sufficiently above the Benchmark Index Value.

  Dividend Rates in the United States.   If dividend rates on the stocks
comprising the Index increase, the trading value of the Securities is expected
to decrease. Conversely, if dividend rates on the stocks comprising the Index
decrease, the value of the Securities is expected to increase. However, in
general, rising U.S. corporate dividend rates may increase the value of the
Index and, in turn, increase the trading value of the Securities. Conversely,
falling U.S. corporate dividend rates may decrease the value of the Index and,
in turn, decrease the trading value of the Securities.

  The impact of the factors specified above, excluding the value of the Index,
may offset, partially or in whole, any increase in the trading value of the
Securities that is attributable to an increase in the value of the Index. For
example, an increase in U.S. interest rates may cause the Securities to trade at
a discount from their initial offering price, even if the Index has appreciated
significantly. In addition, the impact of a given factor may change depending on
the prevailing value of the Index relative to the Benchmark Index Value and the
Maximum Index Value and on the time remaining to maturity. In general, assuming
all relevant factors are held constant, the effect on the trading value of the
Securities of a given change in interest rates, Index volatility and/or dividend
rates of stocks comprising the Index is expected to be less if it occurs later
in the term of the Securities than if it occurs earlier in the term of the
Securities. The effect on the trading value of the Securities of a given
appreciation of the Index in excess of the Benchmark Index Value is expected to
be greater if it occurs later in the term of the Securities than if it occurs
earlier in the term of the Securities, assuming all other relevant factors are
held constant.


THE INDEX

  The value of the Index and the Supplemental Redemption Amount, if any, may be
adversely affected by political, economic and other developments that affect the
stocks underlying the Index. Since the stocks underlying the Index are of
companies involved in various aspects of the high technology industry segment,
factors affecting this industry segment may affect the value of the Index and
therefore the trading value of the Securities.


OTHER CONSIDERATIONS

  It is suggested that prospective investors who consider purchasing the
Securities should reach an investment decision only after carefully considering
the suitability of the Securities in light of their particular circumstances.

  Investors should also consider the tax consequences of investing in the
Securities and should consult their tax advisors.

  MLPF&S or its affiliates may from time to time engage in transactions
involving the stocks underlying the Index for their proprietary accounts and for
other accounts under their management, which may influence the value of such
stocks and therefore the value of the Securities. MLPF&S and its affiliates will
also be the counterparties to the hedge of the Company's obligations under the
Securities.  Accordingly, under certain circumstances, conflicts

                                       5
<PAGE>
 
of interest may arise between MLPF&S's responsibilities as Calculation Agent
with respect to the Securities and its obligations under its hedge and its
status as a subsidiary of the Company. Under certain circumstances, the duties
of MLPF&S as Calculation Agent in determining the existence of Market Disruption
Events could conflict with the interests of MLPF&S as an affiliate of the issuer
of the Securities, Merrill Lynch & Co., Inc., and with the interests of the
holders of the Securities.


                           DESCRIPTION OF SECURITIES

GENERAL

  The Securities were issued as a series of Senior Debt Securities under the
Senior Indenture, referred to as the "Senior Indenture", which is more fully
described below.  The Securities will mature on August 15, 2001.

  At maturity, a beneficial owner of a Security will receive the principal
amount of such Security plus the Supplemental Redemption Amount, if any,
however, there will be no other payment of interest, periodic or otherwise. (See
"Payment at Maturity" below.)

  The Securities are not subject to redemption by the Company or at the option
of any beneficial owner prior to maturity. Upon the occurrence of an Event of
Default with respect to the Securities, beneficial owners of the Securities may
accelerate the maturity of the Securities, as described under "Description of
Securities--Events of Default and Acceleration" in this Prospectus and "Other
Terms--Events of Default" in this Prospectus.

  The Securities were issued in denominations of whole Units.


PAYMENT AT MATURITY

  At maturity, a beneficial owner of a Security will be entitled to receive the
principal amount thereof plus a Supplemental Redemption Amount, if any, all as
provided below. If the Ending Index Value does not exceed the Benchmark Index
Value a beneficial owner of a Security will be entitled to receive only the
principal amount thereof.

  At maturity, a beneficial owner of a Security will be entitled to receive,
with respect to each such Security, (i) the principal amount thereof ($10 for
each Unit), and (ii) the Supplemental Redemption Amount equal in amount to:

Principal Amount  X    Ending Index Value--Benchmark Index Value
                       -----------------------------------------
                                 Benchmark Index Value

provided, however, that in no event will the Supplemental Redemption Amount be
less than zero or more than $10 per $10 principal amount of Securities. The
Benchmark Index Value equals 189.48. The Benchmark Index Value was determined on
the Pricing Date by multiplying the closing value of the Index on the Pricing
Date by a factor equal to 112.5%. The Ending Index Value will be determined by
MLPF&S (the "Calculation Agent") and will equal the average (arithmetic mean) of
the closing values of the Index determined on each of the first five Calculation
Days during the Calculation Period. If there are fewer than five Calculation
Days, then the Ending Index Value will equal the average (arithmetic mean) of
the closing values of the Index on such Calculation Days, and if there is only
one Calculation Day, then the Ending Index Value will equal the closing value of
the Index on such Calculation Day. If no Calculation Days occur during the
Calculation Period because of Market Disruption Events, then the Ending Index
Value will equal the closing value of the Index determined on the last scheduled
Index Business Day in the Calculation Period, regardless of the occurrence of a
Market Disruption Event on such day. The "Calculation

Period" means the period from and including the seventh scheduled Index Business
Day prior to the maturity date to and including the second scheduled Index
Business Day prior to the maturity date. "Calculation Day" means any Index
Business Day during the Calculation Period on which a Market Disruption Event
has not occurred. For purposes of determining the Ending Index Value, an "Index
Business Day" is a day on which the NYSE is open for trading and trading
generally occurs in the over-the-counter market for equity securities and the
Index or any Successor Index is calculated and published. All determinations
made by the Calculation Agent shall be at the sole discretion of the Calculation
Agent and, absent a determination by the Calculation Agent of a manifest error,
shall be conclusive for all purposes and binding on the Company and beneficial
owners of the Securities.

  The following table illustrates, for a range of hypothetical Ending Index
Values, (i) the total amount payable at maturity for each $10 principal amount
of Securities, (ii) the pretax annualized rate of return to beneficial owners of
Securities, and (iii) the pretax annualized rate of return of an investment in
the stocks underlying the Index (which includes an assumed aggregate dividend
yield of 0.20% per annum, as more fully described below).

(1) The annualized rates of return specified in the preceding table are
    calculated on a semiannual bond equivalent basis.

(2) This rate of return assumes (i) an investment of a fixed amount in the
    stocks underlying the Index with the allocation of such amount reflecting
    the relative weights of such stocks in the Index; (ii) a percentage change
    in the aggregate price of such stocks that equals the percentage change in
    the Index from the closing value of the Index on the Pricing Date to the
    relevant hypothetical Ending Index Value; (iii) a constant dividend yield of
    0.20% per annum, paid quarterly from the date of initial delivery of
    Securities, applied to the value of the Index at the end of each such
    quarter assuming such value increases or decreases linearly from the closing
    value of the Index on the Pricing Date to the applicable hypothetical Ending
    Index Value; (iv) no transaction fees or expenses; (v) an investment term
    equal to the term of the Securities; and (vi) a final Index value equal to
    the

                                       7
<PAGE>
 
    Ending Index Value. The aggregate dividend yield of the stocks underlying
    the Index as of August 7, 1996 was approximately 0.20%.

(3) The closing value of the Index on the Pricing Date.

  The above figures are for purposes of illustration only. The actual
Supplemental Redemption Amount received by investors and the pretax annualized
rate of return resulting therefrom will depend entirely on the actual Ending
Index Value determined by the Calculation Agent as provided herein. Historical
data regarding the Index is included in this Prospectus under "The Index--
Historical Data on the Index".

ADJUSTMENTS TO THE INDEX; MARKET DISRUPTION EVENTS

  If at any time the method of calculating the Index, or the value thereof, is
changed in any material respect, or if the Index is in any other way modified so
that such Index does not, in the opinion of the Calculation Agent, fairly
represent the value of the Index had such changes or modifications not been
made, then, from and after such time, the Calculation Agent shall, at the close
of business in New York, New York, on each date that the closing value with
respect to the Ending Index Value is to be calculated, make such adjustments as,
in the good faith judgment of the Calculation Agent, may be necessary in order
to arrive at a calculation of a value of a stock index comparable to the Index
as if such changes or modifications had not been made, and calculate such
closing value with reference to the Index, as adjusted. Accordingly, if the
method of calculating the Index is modified so that the value of such Index is a
fraction or a multiple of what it would have been if it had not been modified
(e.g., due to a split in the Index), then the Calculation Agent shall adjust
such Index in order to arrive at a value of the Index as if it had not been
modified (e.g., as if such split had not occurred).

  "Market Disruption Event" means either of the following events, as determined
by the Calculation Agent:

  (i) the suspension or material limitation (limitations pursuant to New York
Stock Exchange Rule 80A (or any applicable rule or regulation enacted or
promulgated by the New York Stock Exchange or any other self regulatory
organization or the Commission of similar scope as determined by the Calculation
Agent) on trading during significant market fluctuations shall be considered
"material" for purposes of this definition), in each case, for more than two
hours of trading in 5 or more of the securities included in the Index, or

  (ii) the suspension or material limitation, in each case, for more than two
hours of trading (whether by reason of movements in price otherwise exceeding
levels permitted by the relevant exchange or otherwise) in option contracts on
the Index which are traded on the Chicago Board Options Exchange, Inc.

  For the purposes of this definition, a limitation on the hours in a trading
day and/or number of days of trading will not constitute a Market Disruption
Event if it results from an announced change in the regular business hours of
the relevant exchange.

DISCONTINUANCE OF THE INDEX

  If the CBOE discontinues publication of the Index and the CBOE or another
entity publishes a successor or substitute index that the Calculation Agent
determines, in its sole discretion, to be comparable to such Index (any such
index being referred to hereinafter as a "Successor Index"), then, upon the
Calculation Agent's notification of such determination to the Trustee (as
defined below) and the Company, the Calculation Agent will substitute the
Successor Index as calculated by the CBOE or such other entity for the Index and
calculate the Ending Index Value as described above under "Payment at Maturity".
Upon any selection by the Calculation Agent of a Successor Index, the Company
shall cause notice thereof to be given to Holders of the Securities.

  If the CBOE discontinues publication of the Index and a Successor Index is not
selected by the Calculation Agent or is no longer published on any of the
Calculation Days, the value to be substituted for the Index for any

                                       8
<PAGE>
 
such Calculation Day used to calculate the Supplemental Redemption Amount at
maturity will be a value computed by the Calculation Agent for each Calculation
Day in accordance with the procedures last used to calculate the Index prior to
any such discontinuance. If a Successor Index is selected or the Calculation
Agent calculates a value as a substitute for the Index as described below, such
Successor Index or value shall be substituted for the Index for all purposes,
including for purposes of determining whether a Market Disruption Event exists.

  If the CBOE discontinues publication of the Index prior to the period during
which the Supplemental Redemption Amount is to be determined and the Calculation
Agent determines that no Successor Index is available at such time, then on each
Business Day until the earlier to occur of (i) the determination of the Ending
Index Value and (ii) a determination by the Calculation Agent that a Successor
Index is available, the Calculation Agent shall determine the value that would
be used in computing the Supplemental Redemption Amount as described in the
preceding paragraph as if such day were a Calculation Day. The Calculation Agent
will cause notice of each such value to be published not less often than once
each month in The Wall Street Journal (or another newspaper of general
circulation), and arrange for information with respect to such values to be made
available by telephone. Notwithstanding these alternative arrangements,
discontinuance of the publication of the Index may adversely affect trading in
the Securities.


EVENTS OF DEFAULT AND ACCELERATION

  In case an Event of Default with respect to any Securities shall have occurred
and be continuing, the amount payable to a beneficial owner of a Security upon
any acceleration permitted by the Securities, with respect to each $10 principal
amount thereof, will be equal to: (i) the initial issue price ($10), plus (ii)
an additional amount of contingent interest calculated as though the date of
early repayment were the maturity date of the Securities. See "Description of
Securities--Payment at Maturity" in this Prospectus. If a bankruptcy proceeding
is commenced in respect of the Company, the claim of the beneficial owner of a
Security may be limited, under Section 502(b)(2) of Title 11 of the United
States Code, to the principal amount of the Security plus an additional amount
of contingent interest calculated as though the date of the commencement of the
proceeding were the maturity date of the Securities.

  In case of default in payment at the maturity date of the Securities (whether
at their stated maturity or upon acceleration), from and after the maturity date
the Securities shall bear interest, payable upon demand of the beneficial owners
thereof, at the rate of 7.76% per annum (to the extent that payment of such
interest shall be legally enforceable) on the unpaid amount due and payable on
such date in accordance with the terms of the Securities to the date payment of
such amount has been made or duly provided for.


DEPOSITORY

  Upon issuance, all Securities will be represented by one or more fully
registered global securities (the "Global Securities"). Each such Global
Security will be deposited with, or on behalf of, The Depository Trust Company
("DTC"), as Depository (the "Depository"), registered in the name of DTC or a
nominee thereof. Unless and until it is exchanged in whole or in part for
Securities in definitive form, no Global Security may be transferred except as a
whole by the Depository to a nominee of such Depository or by a nominee of such
Depository to such Depository or another nominee of such Depository or by such
Depository or any such nominee to a successor of such Depository or a nominee of
such successor.

  DTC has advised the Company as follows: DTC is a limited-purpose trust company
organized under the Banking Law of the State of New York, a member of the
Federal Reserve System, a "clearing corporation" within the meaning of the New
York Uniform Commercial Code, and a "clearing agency" registered pursuant to the
provisions of Section 17A of the Exchange Act.  DTC was created to hold
securities of its participants ("Participants") and to

                                       9
<PAGE>
 
facilitate the clearance and settlement of securities transactions among its
Participants in such securities through electronic book-entry changes in
accounts of the Participants, thereby eliminating the need for physical movement
of securities certificates. DTC's Participants include securities brokers and
dealers, banks, trust companies, clearing corporations, and certain other
organizations.

  DTC is owned by a number of Participants and by the New York Stock Exchange,
Inc., the American Stock Exchange, Inc. and the National Association of
Securities Dealers, Inc. Access to the DTC book-entry system is also available
to others, such as banks, brokers, dealers and trust companies that clear
through or maintain a custodial relationship with a Participant, either directly
or indirectly ("Indirect Participants").

  Purchases of Securities must be made by or through Participants, which will
receive a credit on the records of DTC. The ownership interest of each actual
purchaser of each Security ("Beneficial Owner") is in turn to be recorded on the
Participants' or Indirect Participants' records. Beneficial Owners will not
receive written confirmation from DTC of their purchase, but Beneficial Owners
are expected to receive written confirmations providing details of the
transaction, as well as periodic statements of their holdings, from the
Participant or Indirect Participant through which the Beneficial Owner entered
into the transaction. Ownership of beneficial interests in such Global Security
will be shown on, and the transfer of such ownership interests will be effected
only through, records maintained by DTC (with respect to interests of
Participants) and on the records of Participants (with respect to interests of
persons held through Participants). The laws of some states may require that
certain purchasers of securities take physical delivery of such securities in
definitive form. Such limits and such laws may impair the ability to own,
transfer or pledge beneficial interests in Global Securities.

  So long as DTC, or its nominee, is the registered owner of a Global Security,
DTC or its nominee, as the case may be, will be considered the sole owner or
Holder of the Securities represented by such Global Security for all purposes
under the Senior Indenture. Except as provided below, Beneficial Owners in a
Global Security will not be entitled to have the Securities represented by such
Global Securities registered in their names, will not receive or be entitled to
receive physical delivery of the Securities in definitive form and will not be
considered the owners or Holders thereof under the Senior Indenture, including
for purposes of receiving any reports delivered by the Company or the Trustee
pursuant to the Senior Indenture. Accordingly, each Person owning a beneficial
interest in a Global Security must rely on the procedures of DTC and, if such
Person is not a Participant, on the procedures of the Participant through which
such Person owns its interest, to exercise any rights of a Holder under the
Senior Indenture. The Company understands that under existing industry
practices, in the event that the Company requests any action of Holders or that
an owner of a beneficial interest in such a Global Security desires to give or
take any action which a Holder is entitled to give or take under the Senior
Indenture, DTC would authorize the Participants holding the relevant beneficial
interests to give or take such action, and such Participants would authorize
Beneficial Owners owning through such Participants to give or take such action
or would otherwise act upon the instructions of Beneficial Owners. Conveyance of
notices and other communications by DTC to Participants, by Participants to
Indirect Participants, and by Participants and Indirect Participants to
Beneficial Owners will be governed by arrangements among them, subject to any
statutory or regulatory requirements as may be in effect from time to time.

  Payment of the principal of, and any Supplemental Redemption Amount with
respect to, Securities registered in the name of DTC or its nominee will be made
to DTC or its nominee, as the case may be, as the Holder of the Global
Securities representing such Securities. None of the Company, the Trustee or any
other agent of the Company or agent of the Trustee will have any responsibility
or liability for any aspect of the records relating to or payments made on
account of beneficial ownership interests or for supervising or reviewing any
records relating to such beneficial ownership interests. The Company expects
that DTC, upon receipt of any payment of principal or any Supplemental
Redemption Amount in respect of a Global Security, will credit the accounts of
the Participants with payment in amounts proportionate to their respective
holdings in principal amount of beneficial interest in such Global Security as
shown on the records of DTC. The Company also expects that payments by
Participants to Beneficial Owners will be governed by standing customer
instructions and customary practices, as is now the case

                                       10
<PAGE>
 
with securities held for the accounts of customers in bearer form or registered
in "street name", and will be the responsibility of such Participants.

  If (x) any Depository is at any time unwilling or unable to continue as
Depository and a successor depository is not appointed by the Company within 60
days, (y) the Company executes and delivers to the Trustee a Company Order to
the effect that the Global Securities shall be exchangeable or (z) an Event of
Default has occurred and is continuing with respect to the Securities, the
Global Securities will be exchangeable for Securities in definitive form of like
tenor and of an equal aggregate principal amount, in denominations of $10 and
integral multiples thereof. Such definitive Securities shall be registered in
such name or names as the Depository shall instruct the Trustee. It is expected
that such instructions may be based upon directions received by the Depository
from Participants with respect to ownership of beneficial interests in such
Global Securities.


SAME-DAY SETTLEMENT AND PAYMENT

  All payments of principal and the Supplemental Redemption Amount, if any, will
be made by the Company in immediately available funds so long as the Securities
are maintained in book-entry form.


                                   THE INDEX

THE INDEX

  Unless otherwise stated, all information herein on the Index is derived from
the CBOE or other publicly available sources. Such information reflects the
policies of the CBOE as stated in such sources and such policies are subject to
change by the CBOE.

  The Index is a price-weighted stock index designed, developed, maintained and
operated by, and is a service mark of, the CBOE. The Index is designed to
provide an indication of the composite price performance of the common stocks of
companies involved in the U.S. high technology industry segment (i.e., companies
involved in the design and manufacture of high technology components and
systems). The Index consists of the stocks of 30 issuers involved in various
aspects of the high technology industry segment, including: computer services,
telecommunications equipment, server software and hardware, design software, PC
software and hardware, networking, peripherals, and semiconductors. (See the
table below for a list of the stocks underlying the Index as of August 5, 1996.)
The CBOE selects companies for inclusion in the Index with the aim of
representing the spectrum of companies that develop components and systems that
define high technology. Relevant criteria employed by the CBOE include the
viability of the particular company, the extent to which that company represents
the high technology sector, the extent to which the market price of that
company's common stock is generally responsive to changes in the affairs of the
technology sector and the market value and trading activity of the common stock
of that company. As of August 5, 1996, the 30 companies included in the Index
were divided into five main individual groups. These individual groups comprised
the following (with the number of companies currently included in each group
indicated in parentheses): Computer Hardware (8), Computer Software (6),
Computer Systems & Services (6), Telecommunications (5) and Semiconductors (5).
The CBOE may from time to time, in its sole discretion, add companies to, or
delete companies from, the Index to achieve the objectives stated above. The
Index has a base date of January 3, 1995.

  The common stocks comprising the Index are currently listed either on the New
York Stock Exchange or traded through the facilities of the National Association
of Securities Dealers Automated Quotation System and reported as National Market
System securities.  As of August 5, 1996, the 30 companies included in the Index
had an aggregate market value of $445.9 billion, with an average capitalization
of $14.86 billion. The Index components ranged in size from $906.6 million to
$72.3 billion, with a median capitalization of $4.81 billion. All of the stocks
are currently the subject of listed options trading in the U.S.

                                       11
<PAGE>
 
  The average monthly trading volumes per Index component over the six month
period ending July 31, 1996 ranged from a low of 5.65 million shares to a high
of 177.6 million shares. As of August 5, 1996, the largest stock in the Index,
by value, accounted for 8.88% of the Index, while the smallest represented 0.78%
of the Index. Also on that date, the top five stocks in the Index accounted for
32.26% of the Index by value.

  The Index satisfies the CBOE's generic maintenance standards for options on
narrow-based stock indexes.


COMPUTATION OF THE INDEX

  The Index is a price-weighted index (i.e., the weight in the Index of a stock
underlying the Index (an "Underlying Stock") is based on its price per share
rather than the total market capitalization of the issuer of such stock) and
reflects changes in the prices of the Underlying Stocks relative to the index
base date, January 3, 1995, when the Index equaled 100.00. Specifically, the
Index value is calculated by (i) totaling the prices of a single share of each
of the Underlying Stocks (the "Market Price Aggregate"), and (ii) dividing the
Market Price Aggregate by the Index Divisor. The Index Divisor was originally
chosen to result in an Index value of 100 on January 3, 1995, and is subject to
periodic adjustments as set forth below. The stock prices used to calculate the
Index are those reported by a primary market for the Underlying Stocks.

  The CBOE adjusts the foregoing Index Divisor to negate the effects of changes
in the price of an Underlying Stock that are determined by the CBOE to be
arbitrary and not due to market fluctuations. Such adjustments may result from
stock splits, certain consolidations and acquisitions, the grant to shareholders
of the right to purchase other securities of the issuer (e.g., spinoffs and
rights issuances). The CBOE may also adjust the Index Divisor because of the
substitution of an Underlying Security. In all such cases, the CBOE first
recalculates the Market Price Aggregate and then determines a new Index Divisor
based on the following formula:

Old Divisor    X  New Market Price Aggregate     New Divisor
                  --------------------------
                  Old Market Price Aggregate

  The Index will be maintained by the CBOE. The Index is reviewed on
approximately a monthly basis by the CBOE staff. The CBOE may change the
composition of the Index at any time to reflect changes affecting the components
of the Index or the technology industry generally. If it becomes necessary to
remove a stock from the Index (for example, because of a takeover or merger),
the CBOE will only add a stock having characteristics that will permit the Index
to remain within the maintenance criteria specified in CBOE Rules and within the
applicable rules of the Commission. These maintenance criteria currently
provide, among other things, that each component security must have (1) a market
capitalization of at least $75 million, except that securities accounting for
the bottom 10% of the weight of the Index may have market capitalizations of at
least $50 million, and (2) trading volume of at least 500,000 shares in each of
the last six months, except that securities accounting for the bottom 10% of the
weight of the Index may have trading volumes of at least 400,000 shares in each
of the last six months. Additionally, as of the first trading day of each
January and July, no single security may account for over 25% of the weight of
the Index and no five securities may account for over 50% of the weight of the
Index. Furthermore, each component security must be a reported security as
defined in Rule 11Aa3-1 of the Exchange Act. Finally, at least 90% of the weight
of the Index and 80% of the number of components in the Index must be eligible
for standardized options trading pursuant to CBOE Rules or, if currently listed
for options trading, must meet the applicable maintenance standards specified in
CBOE Rules. The CBOE will also take into account the capitalizations, liquidity,
volatility, and name recognition of any proposed replacement stock.

  Absent prior approval of the Commission, the CBOE will not increase to more
than 40, or decrease to fewer than 20, the number of stocks in the Index.
Additionally, the CBOE will not make any change in the composition of the Index
that would cause fewer than 90% of the stocks by weight, or fewer than 80% of
the total number of stocks in the index, to qualify as stocks eligible for
equity options trading under CBOE rules.

  The CBOE is under no obligation to continue the calculation and dissemination
of the Index and the method by which the Index is calculated and the name "CBOE
Technology Index" may be changed at the discretion of the CBOE. The Securities
are not sponsored, endorsed, sold or promoted by the CBOE. No inference should
be drawn from the information contained in this Prospectus that the CBOE makes
any representation or warranty, implied or express, to the Company, the
beneficial owners of Securities or any member of the public regarding the
advisability of investing in securities generally or in the Securities in
particular or the ability of the Index to track general stock market
performance. The CBOE has no obligation to take the needs of the Company or the
beneficial owners of Securities into consideration in determining, composing or
calculating the Index. The CBOE is not responsible for, and has not participated
in the determination of the timing of prices for or quantities of, the
Securities to be issued or in the determination or calculation of the equation
by which the Supplemental Redemption Amount is determined. The CBOE has no
obligation or liability in connection with the administration, marketing or
trading of the Securities.

  The use of and reference to the Index in connection with the Securities have
been consented to by the CBOE.

  Except with respect to the responsibility of the Calculation Agent to make
certain calculations under certain circumstances as described herein, none of
the Company, the Trustee, the Calculation Agent or the Underwriter has
undertaken independent diligence of the calculation, maintenance or publication
of the Index or any Successor Index. The CBOE disclaims all responsibility for
any inaccuracies in the data on which the Index is based and any mistakes or
errors or omissions in the calculation or dissemination of the Index and for the
manner in which the Index is used in determining the Supplemental Redemption
Amount, if any.

  A potential investor should review the historical performance of the Index.
The historical performance of the Index should not be taken as an indication of
future performance, and no assurance can be given that the Index will increase
sufficiently to cause the beneficial owners of the Securities to receive an
amount in excess of the principal amount at the maturity of the Securities.

                                  OTHER TERMS

GENERAL

  The Securities were issued as a series of Senior Debt Securities under the
Indenture (the "Senior Indenture"), dated as of April 1, 1983, as amended and
restated, between the Company and The Chase Manhattan Bank, formerly known as
Chemical Bank (successor by merger to Manufacturers Hanover Trust Company), as
trustee (the "Trustee"). A copy of the Senior Indenture is filed as an exhibit
to the registration statements relating to the Securities. The following
summaries of certain provisions of the Senior Indenture do not purport to be
complete and are subject to, and qualified in their entirety by reference to,
all provisions of the Senior Indenture, including the definition therein of
certain terms.

  The Senior Indenture provides that series of Senior Debt Securities may from
time to time be issued thereunder, without limitation as to aggregate principal
amount, in one or more series and upon such terms as the Company may establish
pursuant to the provisions thereof.

  The Senior Indenture provides that the Senior Indenture and the Securities are
governed by and construed in accordance with the laws of the State of New York.

  The Senior Indenture provides that the Company may issue Senior Debt
Securities with terms different from those of Senior Debt Securities previously
issued, and "reopen" a previously issued series of Senior Debt Securities and
issue additional Senior Debt Securities of such series.

  The Senior Debt Securities are unsecured and rank pari passu with all other
unsecured and unsubordinated indebtedness of the Company.  However, since the
Company is a holding company, the right of the Company, and hence the right of
creditors of the Company (including the Holders of Senior Debt Securities), to
participate in any

                                       13
<PAGE>
 
distribution of the assets of any subsidiary upon its liquidation or
reorganization or otherwise is necessarily subject to the prior claims of
creditors of the subsidiary, except to the extent that claims of the Company
itself as a creditor of the subsidiary may be recognized.  In addition,
dividends, loans and advances from certain subsidiaries, including MLPF&S, to
the Company are restricted by net capital requirements under the Exchange Act
and under rules of certain exchanges and other regulatory bodies.


LIMITATIONS UPON LIENS

  The Company may not, and may not permit any Subsidiary to, create, assume,
incur or permit to exist any indebtedness for borrowed money secured by a
pledge, lien or other encumbrance (except for certain liens specifically
permitted by the Senior Indenture) on the Voting Stock owned directly or
indirectly by the Company of any Subsidiary (other than a Subsidiary which, at
the time of the incurrence of such secured indebtedness, has a net worth of less
than $3,000,000) without making effective provision whereby the Outstanding
Senior Debt Securities will be secured equally and ratably with such secured
indebtedness.


LIMITATION ON DISPOSITION OF VOTING STOCK OF, AND MERGER AND SALE OF ASSETS BY,
MLPF&S

  The Indenture provides that the Company may not sell, transfer or otherwise
dispose of any Voting Stock of MLPF&S or permit MLPF&S to issue, sell or
otherwise dispose of any of its Voting Stock, unless, after giving effect to any
such transaction, MLPF&S remains a Controlled Subsidiary (defined in the Senior
Indenture to mean a corporation more than 80% of the outstanding shares of
Voting Stock of which are owned directly or indirectly by the Company).  In
addition, the Company may not permit MLPF&S to (i) merge or consolidate, unless
the surviving company is a Controlled Subsidiary or (ii) convey or transfer its
properties and assets substantially as an entirety, except to one or more
Controlled Subsidiaries.


MERGER AND CONSOLIDATION

  The Indenture provides that the Company may consolidate or merge with or into
any other corporation, and the Company may sell, lease or convey all or
substantially all of its assets to any corporation, provided that (i) the
corporation (if other than the Company) formed by or resulting from any such
consolidation or merger or which shall have received such assets shall be a
corporation organized and existing under the laws of the United States of
America or a state thereof and shall assume payment of the principal of (and
premium, if any) and interest on the Senior Debt Securities and the performance
and observance of all of the covenants and conditions of the Senior Indenture to
be performed or observed by the Company, and (ii) the Company or such successor
corporation, as the case may be, shall not immediately thereafter be in default
under the Senior Indenture.


MODIFICATION AND WAIVER

  Modification and amendment of the Indenture may be effected by the Company and
the Trustee with the consent of the Holders of 66 2/3% in principal amount of
the Outstanding Senior Debt Securities of each series issued pursuant to such
indenture and affected thereby, provided that no such modification or amendment
may, without the consent of the Holder of each Outstanding Senior Debt Security
affected thereby, (a) change the Stated Maturity of the principal of, or any
installment of interest or Additional Amounts payable on, any Senior Debt
Security or any premium payable on the redemption thereof, or change the
Redemption Price; (b) reduce the principal amount of, or the interest or
Additional Amounts payable on, any Senior Debt Security or reduce the amount of
principal which could be declared due and payable prior to the Stated Maturity;
(c) change place or currency of any payment of principal or any premium,
interest or Additional Amounts payable on any Senior Debt Security; (d) impair
the right to institute suit for the enforcement of any payment on or with
respect to any Senior Debt Security; (e) reduce the

                                       14
<PAGE>
 
percentage in principal amount of the Outstanding Senior Debt Securities of any
series, the consent of whose Holders is required to modify or amend the
Indenture; or (f) modify the foregoing requirements or reduce the percentage of
Outstanding Senior Debt Securities necessary to waive any past default to less
than a majority.  No modification or amendment of the Subordinated Indenture or
any Subsequent Indenture for Subordinated Debt Securities may adversely affect
the rights of any holder of Senior Indebtedness without the consent of such
Holder.  Except with respect to certain fundamental provisions, the Holders of
at least a majority in principal amount of Outstanding Senior Debt Securities of
any series may, with respect to such series, waive past defaults under the
Indenture and waive compliance by the Company with certain provisions thereof.


EVENTS OF DEFAULT

  Under the Senior Indenture, the following will be Events of Default with
respect to Senior Debt Securities of any series: (a) default in the payment of
any interest or Additional Amounts payable on any Senior Debt Security of that
series when due, continued for 30 days; (b) default in the payment of any
principal or premium, if any, on any Senior Debt Security of that series when
due; (c) default in the deposit of any sinking fund payment, when due, in
respect of any Senior Debt Security of that series; (d) default in the
performance of any other covenant of the Company contained in the Indenture for
the benefit of such series or in the Senior Debt Securities of such series,
continued for 60 days after written notice as provided in the Senior Indenture;
(e) certain events in bankruptcy, insolvency or reorganization; and (f) any
other Event of Default provided with respect to Senior Debt Securities of that
series.  The Trustee or the Holders of 25% in principal amount of the
Outstanding Senior Debt Securities of that series may declare the principal
amount (or such lesser amount as may be provided for in the Senior Debt
Securities of that series) of all Outstanding Senior Debt Securities of that
series and the interest due thereon and Additional Amounts payable in respect
thereof, if any to be due and payable immediately if an Event of Default with
respect to Senior Debt Securities of such series shall occur and be continuing
at the time of such declaration.  At any time after a declaration of
acceleration has been made with respect to Senior Debt Securities of any series
but before a judgment or decree for payment of money due has been obtained by
the Trustee, the Holders of a majority in principal amount of the Outstanding
Senior Debt Securities of that series may rescind any declaration of
acceleration and its consequences, if all payments due (other than those due as
a result of acceleration) have been made and all Events of Default have been
remedied or waived.  Any Event of Default with respect to Senior Debt Securities
of any series may be waived by the Holders of a majority in principal amount of
all Outstanding Senior Debt Securities of that series, except in a case of
failure to pay principal or premium, if any, or interest or Additional Amounts
payable on any Senior Debt Security of that series for which payment had not
been subsequently made or in respect of a covenant or provision which cannot be
modified or amended without the consent of the Holder of each Outstanding Senior
Debt Security of such series affected.

  The Holders of a majority in principal amount of the Outstanding Senior Debt
Securities of a series may 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 Senior Debt Securities of such
series, provided that such direction shall not be in conflict with any rule of
law or the Senior Indenture.  Before proceeding to exercise any right or power
under the Senior Indenture at the direction of such Holders, the Trustee shall
be entitled to receive from such Holders reasonable security or indemnity
against the costs, expenses and liabilities which might be incurred by it in
complying with any such direction.

  The Company is required to furnish to the Trustee annually a statement as to
the fulfillment by the Company of all of its obligations under the Senior
Indenture.

    HEALTHCARE/BIOTECHNOLOGY PORTFOLIO MARKET INDEX TARGET-TERM SECURITIES(SM)
                              DUE OCTOBER 31, 2001
                                  ("MITTS(R)")

  On October 30, 1996, Merrill Lynch & Co., Inc. (the "Company") issued
$15,000,000 aggregate principal amount (1,500,000 Units) of
Healthcare/Biotechnology Portfolio Market Index Target-Term Securities due
October 31, 2001 (the "Securities" or "MITTS").  Each $10 principal amount of
Securities will be deemed a "Unit" for purposes of trading and transfer at the
Depository described below.  Units will be transferable by the Depository, as
more fully described below, in denominations of whole Units.

  The Securities are debt securities of the Company, which were issued in
denominations of $10 and integral multiples thereof, will bear no periodic
payments of interest and will mature on October 31, 2001. At maturity, a
beneficial owner of a Security will be entitled to receive, with respect to each
Security, the principal amount thereof plus an interest payment (the
"Supplemental Redemption Amount"), based on the percentage increase, if any, in
the value of a portfolio (the "Portfolio Value") of specified stocks (the
"Portfolio") of companies involved in various segments of the healthcare
industry and the biotechnology industry over the Benchmark Portfolio Value. The
Supplemental Redemption Amount will in no event be less than zero. The
Securities are not redeemable or callable by the Company prior to maturity.  At
maturity a beneficial owner of a Security will receive the principal amount of
such Security plus the Supplemental Redemption Amount, if any, however, there
will be no other payment of interest, periodic or otherwise.

  The Supplemental Redemption Amount payable with respect to a Security at
maturity will equal the product of (A) the principal amount of the applicable
Security, and (B) the percentage increase from the Benchmark Portfolio Value to
the Ending Portfolio Value. The Benchmark Portfolio Value equals 115 and was
determined as described herein. The Benchmark Portfolio Value exceeds the
closing value of the Portfolio on the date the Securities were priced by the
Company for initial sale to the Public (the "Pricing Date") by 15%. The Ending
Portfolio Value, as more particularly described herein, will be the average
(arithmetic mean) of the closing values of the Portfolio on certain days, or, if
certain events occur, the closing value of the Portfolio on a single day prior
to the maturity of the Securities.

  FOR INFORMATION AS TO THE CALCULATION OF THE SUPPLEMENTAL REDEMPTION AMOUNT,
IF ANY, WHICH WILL BE PAID AT MATURITY AND THE CALCULATION AND THE COMPOSITION
OF THE PORTFOLIO, SEE "DESCRIPTION OF SECURITIES" AND "THE PORTFOLIO",
RESPECTIVELY, IN THIS PROSPECTUS. FOR OTHER INFORMATION THAT SHOULD BE
CONSIDERED BY PROSPECTIVE INVESTORS, SEE "RISK FACTORS" BEGINNING ON PAGE 3 OF
THIS PROSPECTUS.

  Ownership of the Securities will be maintained in book-entry form by or
through the Depository. Beneficial owners of the Securities will not have the
right to receive physical certificates evidencing their ownership except under
the limited circumstances described herein.

  The Securities have been listed on the American Stock Exchange (the "AMEX")
under the symbol "MLH".

                       RATIO OF EARNINGS TO FIXED CHARGES

  The following table sets forth the historical ratios of earnings to fixed
charges for the periods indicated:

  For the purpose of calculating the ratio of earnings to fixed charges,
"earnings" consists of earnings from continuing operations before income taxes
and fixed charges.  "Fixed charges" consists of interest costs, amortization of
debt expense, preferred stock dividend requirements of majority-owned
subsidiaries, and that portion of rentals estimated to be representative of the
interest factor.


                                  RISK FACTORS
PAYMENT AT MATURITY

  Benchmark Portfolio Value will Exceed Value of Starting Portfolio Value on the
Pricing Date.   On the Pricing Date, the Benchmark Portfolio Value exceeded the
Starting Portfolio Value (as defined below) by 15%. Investors should be aware
that if, at maturity, the Ending Portfolio Value does not exceed the Starting
Portfolio Value by more than 15%, beneficial owners of the Securities will
receive only the principal amount thereof.

                                       3
<PAGE>
 
  Yield may be Below Market Interest Rates on the Pricing Date.   A beneficial
owner of the Securities may receive no Supplemental Redemption Amount at
maturity, or a Supplemental Redemption Amount that is below what the Company
would pay as interest as of the Pricing Date if the Company issued non-callable
senior debt securities with a similar maturity as that of the Securities. The
return of principal of the Securities at maturity and the payment of the
Supplemental Redemption Amount, if any, may not reflect the full opportunity
costs implied by inflation or other factors relating to the time value of money.

  Yield on Securities will not Reflect Dividends.   The Portfolio does not
reflect the payment of dividends on the stocks underlying it and therefore the
yield based on the Portfolio to the maturity of the Securities will not produce
the same yield as if such underlying stocks were purchased and held for a
similar period.

  State Law Limit on Interest Paid.   Because the Senior Indenture (as defined
below) provides that the Securities are governed by and construed in accordance
with the laws of New York, certain usury laws of New York State may apply. Under
present New York law, the maximum rate of interest is 25% per annum on a simple
interest basis. This limit may not apply to Securities in which $2,500,000 or
more has been invested. While the Company believes that New York law would be
given effect by a state or Federal court sitting outside of New York, state laws
frequently regulate the amount of interest that may be charged to and paid by a
borrower (including, in some cases, corporate borrowers). It is suggested that
prospective investors consult their personal advisors with respect to the
applicability of such laws. The Company will covenant for the benefit of the
Holders of the Securities, to the extent permitted by law, not to claim
voluntarily the benefits of any laws concerning usurious rates of interest
against a Holder of the Securities.


TRADING

  The Securities have been listed on the AMEX under the symbol "MLH".  It is
expected that the secondary market for the Securities will be affected by the
creditworthiness of the Company and by a number of other factors.

  The trading value of the Securities is expected to depend substantially on the
extent of the appreciation, if any, of the Portfolio Value over the Benchmark
Portfolio Value.  If, however, Securities are sold prior to the maturity date at
a time when the Portfolio Value exceeds the Benchmark Portfolio Value, the sale
price may be at a substantial discount from the amount expected to be payable to
the beneficial owner if such excess of the Portfolio Value over the Benchmark
Portfolio Value were to prevail until maturity of the Securities because of the
possible fluctuation of the Portfolio between the time of such sale and the time
that the Ending Portfolio Value is determined. Furthermore, the price at which a
beneficial owner will be able to sell Securities prior to maturity may be at a
discount, which could be substantial, from the principal amount thereof, if, at
such time, the Portfolio is below, equal to, or not sufficiently above the
Benchmark Portfolio Value. A discount could also result from rising interest
rates.

  In addition to the value of the Portfolio, the trading value of the Securities
may be affected by a number of interrelated factors, including the
creditworthiness of the Company and those factors listed below. The relationship
among these factors is complex, including how these factors affect the relative
value of the principal amount of the Securities to be repaid at maturity and the
value of the Supplemental Redemption Amount. Accordingly, investors should be
aware that factors other than the level of the Portfolio are likely to affect
the Securities' trading value. The expected effect on the trading value of the
Securities of each of the factors listed below, assuming in each case that all
other factors are held constant, is as follows:

  Interest Rates.   Because the Securities repay at a minimum the principal
amount thereof at maturity, the trading value of the Securities will likely be
affected by changes in interest rates. In general, if U.S. interest rates
increase, the trading value of the Securities is expected to decrease. If U.S.
interest rates decrease, the trading value of the Securities is expected to
increase. Interest rates may also affect the U.S. economy, and, in turn, the
value of the Portfolio. Rising interest rates may lower the value of the
Portfolio and, thus, may decrease the trading value of

                                       4
<PAGE>
 
the Securities. Falling interest rates may increase the value of the Portfolio
and, thus, may increase the trading value of the Securities.

  Volatility of the Portfolio.   If the volatility of the Portfolio Value
increases, the trading value of the Securities is expected to increase. If the
volatility of the Portfolio Value decreases, the trading value of the Securities
is expected to decrease.

  Time Remaining to Maturity.   The Securities may trade at a value above that
which may be inferred from the level of interest rates and the Portfolio. This
difference will reflect a "time premium" due to expectations concerning the
value of the Portfolio during the period prior to maturity of the Securities. As
the time remaining to maturity of the Securities decreases, however, this time
premium is expected to decrease, thus decreasing the trading value of the
Securities. In addition, the price at which a beneficial owner may be able to
sell Securities prior to maturity may be at a discount, which may be
substantial, from the principal amount of the Securities if the value of the
Portfolio is below, equal to, or not sufficiently above the Benchmark Portfolio
Value.

  Dividend Rates in the United States.   If dividend rates on the stocks
comprising the Portfolio increase, the trading value of the Securities is
expected to decrease. Conversely, if dividend rates on the stocks comprising the
Portfolio decrease, the value of the Securities is expected to increase.
However, in general, rising U.S. corporate dividend rates may increase the value
of the Portfolio and, in turn, increase the trading value of the Securities.
Conversely, falling U.S. corporate dividend rates may decrease the value of the
Portfolio and, in turn, decrease the trading value of the Securities.

  The impact of the factors specified above, excluding the value of the
Portfolio, may offset, partially or in whole, any increase in the trading value
of the Securities that is attributable to an increase in the value of the
Portfolio. For example, an increase in U.S. interest rates may cause the
Securities to trade at a discount from their initial offering price, even if the
Portfolio has appreciated significantly. In general, assuming all relevant
factors are held constant, the effect on the trading value of the Securities of
a given change in interest rates, Portfolio volatility and/or dividend rates of
stocks comprising the Portfolio is expected to be less if it occurs later in the
term of the Securities than if it occurs earlier in the term of the Securities.
The effect on the trading value of the Securities of a given appreciation of the
Portfolio in excess of the Benchmark Portfolio Value is expected to be greater
if it occurs later in the term of the Securities than if it occurs earlier in
the term of the Securities, assuming all other relevant factors are held
constant.


THE PORTFOLIO

  The value of the Portfolio and the Supplemental Redemption Amount, if any, may
be adversely affected by political, economic and other developments that affect
the stocks underlying the Portfolio. Since the stocks underlying the Portfolio
are of companies involved in various segments of the healthcare industry and the
biotechnology industry, factors affecting these industries may affect the value
of the Portfolio and therefore the trading value of the Securities. See "The
Portfolio--Healthcare and Biotechnology Industries".


OTHER CONSIDERATIONS

  It is suggested that prospective investors who consider purchasing the
Securities should reach an investment decision only after carefully considering
the suitability of the Securities in light of their particular circumstances.

  Investors should also consider the tax consequences of investing in the
Securities, and should consult their tax advisors.

                                       5
<PAGE>
 
  MLPF&S or its affiliates may from time to time engage in transactions
involving the stocks underlying the Portfolio for their proprietary accounts and
for other accounts under their management, which may influence the value of such
stocks and therefore the value of the Securities. MLPF&S and its affiliates will
also be the counterparties to the hedge of the Company's obligations under the
Securities.  Accordingly, under certain circumstances, conflicts of interest may
arise between MLPF&S's responsibilities as Calculation Agent with respect to the
Securities and its obligations under its hedge and its status as a subsidiary of
the Company. Under certain circumstances, the duties of MLPF&S as Calculation
Agent in determining the existence of Market Disruption Events could conflict
with the interests of MLPF&S as an affiliate of the issuer of the Securities,
Merrill Lynch & Co., Inc., and with the interests of the holders of the
Securities.


                           DESCRIPTION OF SECURITIES

GENERAL

  The Securities were issued as a series of Senior Debt Securities under the
Senior Indenture, referred to as the "Senior Indenture", which is more fully
described below.  The Securities will mature on October 31, 2001.

  At maturity a beneficial owner of a Security will receive the principal amount
of such Security plus the Supplemental Redemption Amount, if any, however, there
will be no other payment of interest, periodic or otherwise. (See "Payment at
Maturity" below.)

  The Securities are not subject to redemption by the Company or at the option
of any beneficial owner prior to maturity. Upon the occurrence of an Event of
Default with respect to the Securities, beneficial owners of the Securities may
accelerate the maturity of the Securities, as described under "Description of
Securities--Events of Default and Acceleration" in this Prospectus and "Other
Terms--Events of Default" in this Prospectus.

  The Securities were issued in denominations of whole Units.


PAYMENT AT MATURITY

  At maturity, a beneficial owner of a Security will be entitled to receive the
principal amount thereof plus a Supplemental Redemption Amount, if any, all as
provided below. If the Ending Portfolio Value does not exceed the Benchmark
Portfolio Value a beneficial owner of a Security will be entitled to receive
only the principal amount thereof.

  At maturity, a beneficial owner of a Security will be entitled to receive,
with respect to each such Security, (i) the principal amount thereof ($10 for
each Unit), and (ii) the Supplemental Redemption Amount equal in amount to:

      Principal Amount x Ending Portfolio Value--Benchmark Portfolio Value
                         -------------------------------------------------
                                    Benchmark Portfolio Value

provided, however, that in no event will the Supplemental Redemption Amount be
less than zero. The Benchmark Portfolio Value equals 115. The Benchmark
Portfolio Value was determined on the Pricing Date by multiplying the Starting
Portfolio Value (as defined below) by a factor equal to 115%. Based on the
individual prices of the Portfolio Securities on the Pricing Date, the
Multiplier for each Portfolio Security was initially set by the AMEX so that, on
the Pricing Date, the Portfolio Securities were equally dollar-weighted in the
Portfolio and the Portfolio Value equaled 100 (the "Starting Portfolio Value").
The Ending Portfolio Value will be determined by MLPF&S (the "Calculation
Agent") and will equal the average (arithmetic mean) of the closing values of
the Portfolio determined on each of the first five Calculation Days during the
Calculation Period. If there are fewer than five

                                       6
<PAGE>
 
Calculation Days, then the Ending Portfolio Value will equal the average
(arithmetic mean) of the closing values of the Portfolio on such Calculation
Days, and if there is only one Calculation Day, then the Ending Portfolio Value
will equal the closing value of the Portfolio on such Calculation Day. If no
Calculation Days occur during the Calculation Period because of Market
Disruption Events, then the Ending Portfolio Value will equal the closing value
of the Portfolio determined on the last scheduled Portfolio Business Day in the
Calculation Period, regardless of the occurrence of a Market Disruption Event on
such day. The "Calculation Period" means the period from and including the
seventh scheduled Portfolio Business Day prior to the maturity date to and
including the second scheduled Portfolio Business Day prior to the maturity
date. "Calculation Day" means any Portfolio Business Day during the Calculation
Period on which a Market Disruption Event has not occurred. For purposes of
determining the Ending Portfolio Value, a "Portfolio Business Day" is a day on
which the AMEX is open for trading and trading generally occurs in the over-the-
counter market for equity securities and the Portfolio or any Successor
Portfolio is calculated and published. All determinations made by the
Calculation Agent shall be at the sole discretion of the Calculation Agent and,
absent a determination by the Calculation Agent of a manifest error, shall be
conclusive for all purposes and binding on the Company and beneficial owners of
the Securities.

  The following table illustrates, for a range of hypothetical Ending Portfolio
Values, (i) the total amount payable at maturity for each $10 principal amount
of Securities, based on the Benchmark Portfolio Value, which equals 115% of the
Starting Portfolio Value; (ii) the pretax annualized rate of return to
beneficial owners of Securities, and (iii) the pretax annualized rate of return
of an investment in the stocks underlying the Portfolio (which includes an
assumed aggregate dividend yield of 0.23% per annum, as more fully described
below).

</TABLE>

(1) The total amount payable at maturity is based on the Benchmark Portfolio
    Value, which equals 115% of the Starting Portfolio Value.
(2) The annualized rates of return specified in the preceding table are
    calculated on a semiannual bond equivalent basis.

                                       7
<PAGE>
 
(3) This rate of return assumes (i) an investment of a fixed amount in the
    stocks underlying the Portfolio with the allocation of such amount
    reflecting the relative weights of such stocks in the Portfolio; (ii) a
    percentage change in the aggregate price of such stocks that equals the
    percentage change in the Portfolio from the Starting Portfolio Value to the
    relevant hypothetical Ending Portfolio Value; (iii) a constant dividend
    yield of 0.23% per annum, paid quarterly from the date of initial delivery
    of Securities, applied to the value of the Portfolio at the end of each such
    quarter assuming such value increases or decreases linearly from the
    Starting Portfolio Value to the applicable hypothetical Ending Portfolio
    Value; (iv) no transaction fees or expenses; (v) a five year maturity of the
    Securities from the date of issuance; and (vi) a final Portfolio value equal
    to the Ending Portfolio Value. The aggregate dividend yield of the stocks
    underlying the Portfolio as of October 24, 1996 was approximately 0.23% per
    annum.
(4) The Starting Portfolio Value was set at 100 based on the closing prices on
    the Pricing Date.

  The above figures are for purposes of illustration only. The actual
Supplemental Redemption Amount received by investors and the pretax annualized
rate of return resulting therefrom will depend entirely on the actual Ending
Portfolio Value determined by the Calculation Agent as provided herein.


ADJUSTMENTS TO THE PORTFOLIO; MARKET DISRUPTION EVENTS

  If at any time the method of calculating the Portfolio Value is changed in any
material respect, or if the Portfolio is in any other way modified so that such
Portfolio Value does not, in the opinion of the Calculation Agent, fairly
represent the Portfolio Value had such changes or modifications not been made,
then, from and after such time, the Calculation Agent shall, at the close of
business in New York, New York, on each date that the closing value with respect
to the Ending Portfolio Value is to be calculated, make such adjustments as, in
the good faith judgment of the Calculation Agent, may be necessary in order to
arrive at a calculation of a value of a stock index comparable to the Portfolio
Value as if such changes or modifications had not been made, and calculate such
closing value with reference to the Portfolio Value, as adjusted. Accordingly,
if the method of calculating the Portfolio Value is modified so that the
Portfolio Value is a fraction or a multiple of what it would have been if it had
not been modified (e.g., due to a split in the Portfolio Value), then the
Calculation Agent shall adjust such Portfolio Value in order to arrive at a
Portfolio Value as if it had not been modified (e.g., as if such split had not
occurred).

  "Market Disruption Event" means either of the following events, as determined
by the Calculation Agent:

  (i) the suspension or material limitation (limitations pursuant to New York
Stock Exchange Rule 80A (or any applicable rule or regulation enacted or
promulgated by the New York Stock Exchange or any other self regulatory
organization or the Commission of similar scope as determined by the Calculation
Agent) on trading during significant market fluctuations shall be considered
"material" for purposes of this definition) in the trading of three or more of
the Portfolio Securities on any exchange in the United States or in the over-
the-counter market for more than two hours of trading or during the period one-
half hour prior to the close of such trading, or

  (ii) the suspension or material limitation (whether by reason of movements in
price otherwise exceeding levels permitted by the relevant exchange or
otherwise) in the trading of option contracts related to three or more of the
Portfolio Securities traded on any exchange for more than two hours of trading
or during the period one-half hour prior to the close of such trading.

  For the purposes of this definition, a limitation on the hours in a trading
day and/or number of days of trading will not constitute a Market Disruption
Event if it results from an announced change in the regular business hours of
the relevant exchange.

                                       8
<PAGE>
 
DISCONTINUANCE OF THE PORTFOLIO

  If the AMEX discontinues publication of the Portfolio Value and the AMEX or
another entity publishes a successor or substitute index that the Calculation
Agent determines, in its sole discretion, to be comparable to such Portfolio
Value (any such index being referred to hereinafter as a "Successor Portfolio
Value"), then, upon the Calculation Agent's notification of such determination
to the Trustee (as defined below) and the Company, the Calculation Agent will
substitute the Successor Portfolio Value as calculated by the AMEX or such other
entity for the Portfolio Value and calculate the Ending Portfolio Value as
described above under "Payment at Maturity". Upon any selection by the
Calculation Agent of a Successor Portfolio Value, the Company shall cause notice
thereof to be given to Holders of the Securities.

  If the AMEX discontinues publication of the Portfolio Value and a Successor
Portfolio Value is not selected by the Calculation Agent or is no longer
published on any of the Calculation Days, the value to be substituted for the
Portfolio Value for any such Calculation Day used to calculate the Supplemental
Redemption Amount at maturity will be a value computed by the Calculation Agent
for each Calculation Day in accordance with the procedures last used to
calculate the Portfolio Value prior to any such discontinuance. If a Successor
Portfolio Value is selected or the Calculation Agent calculates a value as a
substitute for the Portfolio Value as described below, such Successor Portfolio
Value or value shall be substituted for the Portfolio Value for all purposes,
including for purposes of determining whether a Market Disruption Event exists.

  If the AMEX discontinues publication of the Portfolio Value prior to the
period during which the Supplemental Redemption Amount is to be determined and
the Calculation Agent determines that no Successor Portfolio Value is available
at such time, then on each Business Day until the earlier to occur of (i) the
determination of the Ending Portfolio Value and (ii) a determination by the
Calculation Agent that a Successor Portfolio Value is available, the Calculation
Agent shall determine the value that would be used in computing the Supplemental
Redemption Amount as described in the preceding paragraph as if such day were a
Calculation Day. The Calculation Agent will cause notice of each such value to
be published not less often than once each month in The Wall Street Journal (or
another newspaper of general circulation), and arrange for information with
respect to such values to be made available by telephone. Notwithstanding these
alternative arrangements, discontinuance of the publication of the Portfolio
Value may adversely affect trading in the Securities.


EVENTS OF DEFAULT AND ACCELERATION

  In case an Event of Default with respect to any Securities shall have occurred
and be continuing, the amount payable to a beneficial owner of a Security upon
any acceleration permitted by the Securities, with respect to each $10 principal
amount thereof, will be equal to: (i) the initial issue price ($10), plus (ii)
an additional amount of contingent interest calculated as though the date of
early repayment were the maturity date of the Securities. See "Description of
Securities--Payment at Maturity" in this Prospectus.  If a bankruptcy proceeding
is commenced in respect of the Company, the claim of the beneficial owner of a
Security may be limited, under Section 502(b)(2) of Title 11 of the United
States Code, to the principal amount of the Security plus an additional amount
of contingent interest calculated as though the date of the commencement of the
proceeding were the maturity date of the Securities.

  In case of default in payment at the maturity date of the Securities (whether
at their stated maturity or upon acceleration), from and after the maturity date
the Securities shall bear interest, payable upon demand of the beneficial owners
thereof, at the rate of 7.7% per annum (to the extent that payment of such
interest shall be legally enforceable) on the unpaid amount due and payable on
such date in accordance with the terms of the Securities to the date payment of
such amount has been made or duly provided for.

DEPOSITORY

  Upon issuance, all Securities will be represented by one or more fully
registered global securities (the "Global Securities"). Each such Global
Security will be deposited with, or on behalf of, The Depository Trust Company
("DTC"), as Depository (the "Depository"), registered in the name of DTC or a
nominee thereof. Unless and until it is exchanged in whole or in part for
Securities in definitive form, no Global Security may be transferred except as a
whole by the Depository to a nominee of such Depository or by a nominee of such
Depository to such Depository or another nominee of such Depository or by such
Depository or any such nominee to a successor of such Depository or a nominee of
such successor.

  DTC has advised the Company as follows: DTC is a limited-purpose trust company
organized under the Banking Law of the State of New York, a member of the
Federal Reserve System, a "clearing corporation" within the meaning of the New
York Uniform Commercial Code, and a "clearing agency" registered pursuant to the
provisions of Section 17A of the Exchange Act.  DTC was created to hold
securities of its participants ("Participants") and to facilitate the clearance
and settlement of securities transactions among its Participants in such
securities through electronic book-entry changes in accounts of the
Participants, thereby eliminating the need for physical movement of securities
certificates. DTC's Participants include securities brokers and dealers, banks,
trust companies, clearing corporations, and certain other organizations.

  DTC is owned by a number of Participants and by the New York Stock Exchange,
Inc., the American Stock Exchange, Inc. and the National Association of
Securities Dealers, Inc. Access to the DTC book-entry system is also available
to others, such as banks, brokers, dealers and trust companies that clear
through or maintain a custodial relationship with a Participant, either directly
or indirectly ("Indirect Participants").

  Purchases of Securities must be made by or through Participants, which will
receive a credit on the records of DTC. The ownership interest of each actual
purchaser of each Security ("Beneficial Owner") is in turn to be recorded on the
Participants' or Indirect Participants' records. Beneficial Owners will not
receive written confirmation from DTC of their purchase, but Beneficial Owners
are expected to receive written confirmations providing details of the
transaction, as well as periodic statements of their holdings, from the
Participant or Indirect Participant through which the Beneficial Owner entered
into the transaction. Ownership of beneficial interests in such Global Security
will be shown on, and the transfer of such ownership interests will be effected
only through, records maintained by DTC (with respect to interests of
Participants) and on the records of Participants (with respect to interests of
persons held through Participants). The laws of some states may require that
certain purchasers of securities take physical delivery of such securities in
definitive form. Such limits and such laws may impair the ability to own,
transfer or pledge beneficial interests in Global Securities.

  So long as DTC, or its nominee, is the registered owner of a Global Security,
DTC or its nominee, as the case may be, will be considered the sole owner or
Holder of the Securities represented by such Global Security for all purposes
under the Senior Indenture. Except as provided below, Beneficial Owners in a
Global Security will not be entitled to have the Securities represented by such
Global Securities registered in their names, will not receive or be entitled to
receive physical delivery of the Securities in definitive form and will not be
considered the owners or Holders thereof under the Senior Indenture, including
for purposes of receiving any reports delivered by the Company or the Trustee
pursuant to the Senior Indenture. Accordingly, each Person owning a beneficial
interest in a Global Security must rely on the procedures of DTC and, if such
Person is not a Participant, on the procedures of the Participant through which
such Person owns its interest, to exercise any rights of a Holder under the
Senior Indenture. The Company understands that under existing industry
practices, in the event that the Company requests any action of Holders or that
an owner of a beneficial interest in such a Global Security desires to give or
take any action which a Holder is entitled to give or take under the Senior
Indenture, DTC would authorize the Participants holding the relevant beneficial
interests to give or take such action, and such Participants would authorize
Beneficial Owners owning through such Participants to give or take such action
or would otherwise act upon the instructions of Beneficial Owners. Conveyance of
notices and other communications by DTC to Participants, by Participants to

                                       10
<PAGE>
 
Indirect Participants, and by Participants and Indirect Participants to
Beneficial Owners will be governed by arrangements among them, subject to any
statutory or regulatory requirements as may be in effect from time to time.

  Payment of the principal of, and any Supplemental Redemption Amount with
respect to, Securities registered in the name of DTC or its nominee will be made
to DTC or its nominee, as the case may be, as the Holder of the Global
Securities representing such Securities. None of the Company, the Trustee or any
other agent of the Company or agent of the Trustee will have any responsibility
or liability for any aspect of the records relating to or payments made on
account of beneficial ownership interests or for supervising or reviewing any
records relating to such beneficial ownership interests. The Company expects
that DTC, upon receipt of any payment of principal or any Supplemental
Redemption Amount in respect of a Global Security, will credit the accounts of
the Participants with payment in amounts proportionate to their respective
holdings in principal amount of beneficial interest in such Global Security as
shown on the records of DTC. The Company also expects that payments by
Participants to Beneficial Owners will be governed by standing customer
instructions and customary practices, as is now the case with securities held
for the accounts of customers in bearer form or registered in "street name", and
will be the responsibility of such Participants.

  If (x) any Depository is at any time unwilling or unable to continue as
Depository and a successor depository is not appointed by the Company within 60
days, (y) the Company executes and delivers to the Trustee a Company Order to
the effect that the Global Securities shall be exchangeable or (z) an Event of
Default has occurred and is continuing with respect to the Securities, the
Global Securities will be exchangeable for Securities in definitive form of like
tenor and of an equal aggregate principal amount, in denominations of $10 and
integral multiples thereof. Such definitive Securities shall be registered in
such name or names as the Depository shall instruct the Trustee. It is expected
that such instructions may be based upon directions received by the Depository
from Participants with respect to ownership of beneficial interests in such
Global Securities.


SAME-DAY SETTLEMENT AND PAYMENT

  All payments of principal and the Supplemental Redemption Amount, if any, will
be made by the Company in immediately available funds so long as the Securities
are maintained in book-entry form.


                                 THE PORTFOLIO

GENERAL

  While the Portfolio consists of stocks of certain companies involved in
various segments of the healthcare industry and the biotechnology industry, the
Portfolio is not intended to provide an indication of the pattern of price
movements of common stocks of healthcare and biotechnology corporations
generally. All of the Portfolio Securities are registered under the Exchange
Act.  Companies with securities registered under the Exchange Act are required
to file periodically certain financial and other information specified by the
Commission. Information provided to or filed with the Commission is available at
the offices of the Commission and at the Web site specified under "Available
Information" in this Prospectus. Neither the Company nor MLPF&S makes any
representation or warranty as to the accuracy or completeness of such reports.
THE INCLUSION OF A PORTFOLIO SECURITY IN THE PORTFOLIO IS NOT A RECOMMENDATION
TO BUY OR SELL SUCH PORTFOLIO SECURITY AND NEITHER THE COMPANY NOR ANY OF ITS
AFFILIATES MAKE ANY REPRESENTATION TO ANY PURCHASER OF SECURITIES AS TO THE
PERFORMANCE OF THE PORTFOLIO.

  The Company or its affiliates may presently or from time to time engage in
business with one or more of the issuers of the Portfolio Securities, including
extending loans to, or making equity investments in, such issuers or providing
advisory services to such issuers, including merger and acquisition advisory
services. In the course of such business, the Company or its affiliates may
acquire non-public information with respect to such issuers and, in addition,
one or more affiliates of the Company may publish research reports with respect
to such issuers. The

                                       11
<PAGE>
 
Company does not make any representation to any purchaser of Securities with
respect to any matters whatsoever relating to such issuers. Any prospective
purchaser of a Security should undertake an independent investigation of the
issuers of the Portfolio Securities as in its judgment is appropriate to make an
informed decision with respect to an investment in the Securities.


 HEALTHCARE AND BIOTECHNOLOGY INDUSTRIES

  The healthcare industry is subject to various federal, state and local laws
and regulations which are frequently subject to change in many ways that can
affect the price of the stocks of companies involved in such industry.

  A number of legislative bills and proposals to regulate, control or alter
substantially the methods of financing and delivering healthcare, including
proposals covering cost controls, imposition of charitable care requirements,
national health insurance, incentives for competition in the provision of
healthcare insurance premiums, catastrophic illness coverage under Medicare, a
voucher system for Medicare, and the promotion of prepaid healthcare plans, are
currently under discussion, and certain of such bills have been introduced in
Congress. There are wide variations among these bills and proposals, and the
effect of these bills and proposals on the healthcare industry cannot be
determined at this time. Because of the many possible financial effects that
could result from an enactment of any of these bills and proposals, it is not
possible at this time to predict with assurance the effect on the prices of
Portfolio Securities and therefore the Securities if any of these bills or
proposals were enacted.

  The biotechnology industry segment is subject to many of the same factors that
affect the healthcare industry. In addition, the products produced by
biotechnology companies often entail costly research and development and can be
subject to extensive regulatory review prior to approval for sale.

COMPUTATION OF THE PORTFOLIO VALUE

  The AMEX will generally calculate and disseminate the value of the Portfolio
based on the most recently reported prices of the Portfolio Securities (as
reported by the Exchanges), at approximately 15-second intervals during the
AMEX's business hours and at the end of each Portfolio Business Day via the
Consolidated Tape Association's Network B. The Portfolio Value, at any time,
will equal the sum of the products of such prices and the applicable Multipliers
for the Portfolio Securities. The Ending Portfolio Value, however, is calculated
by the Calculation Agent based on averaging the Portfolio Values reported by the
AMEX at the end of certain Portfolio Business Days. See "Description of
Securities--Payment at Maturity". The securities listed below are the Portfolio
Securities and will be used to calculate the value of the Portfolio. Holders of
the MITTS will not have any right to receive the Portfolio Securities. The
following table sets forth the issuers of the Portfolio Securities, the
exchanges, the percentage of each Portfolio Security in the Starting Portfolio
Value and the initial Multipliers:

</TABLE>

  The initial Multiplier relating to each Portfolio Security indicates the
number of shares of such Portfolio Security, given the market price of such
Portfolio Security, required to be included in the calculation of the Starting
Portfolio Value so that each Portfolio Security represents an equal percentage
of the Starting Portfolio Value. The price of each Portfolio Security used to
calculate the initial Multiplier relating to each such Portfolio Security was

                                       13
<PAGE>
 
the closing price of such Portfolio Security on the Pricing Date. The respective
Multipliers will remain constant for the term of the Securities unless adjusted
for certain corporate events, as described below.


ADJUSTMENTS TO THE MULTIPLIER AND PORTFOLIO

  The Multiplier with respect to any Portfolio Security and the Portfolio will
be adjusted as follows:

  1. If a Portfolio Security is subject to a stock split or reverse stock split,
then once such split has become effective, the Multiplier relating to such
Portfolio Security will be adjusted to equal the product of the number of shares
issued with respect to one such share of such Portfolio Security and the prior
multiplier.

  2. If a Portfolio Security is subject to a stock dividend (issuance of
additional shares of the Portfolio Security) that is given equally to all
holders of shares of the issuer of such Portfolio Security, then once the
dividend has become effective and such Portfolio Security is trading ex-
dividend, the Multiplier will be adjusted so that the new Multiplier shall equal
the former Multiplier plus the product of the number of shares of such Portfolio
Security issued with respect to one such share of such Portfolio Security and
the prior multiplier.

  3. There will be no adjustments to the Multipliers to reflect cash dividends
or distributions paid with respect of a Portfolio Security other than for
Extraordinary Dividends as described below. A cash dividend with respect to a
Portfolio Security will be deemed to be an "Extraordinary Dividend" if such
dividend exceeds the immediately preceding non-Extraordinary Dividend for such
Portfolio Security by an amount equal to at least 10% of the market price on the
Portfolio Business Day preceding the record day for the payment of such
Extraordinary Dividend (the "ex-dividend date"). If an Extraordinary Dividend
occurs with respect to a Portfolio Security, the Multiplier with respect to such
Portfolio Security will be adjusted on the ex-dividend date with respect to such
Extraordinary Dividend so that the new Multiplier will equal the product of (i)
the then current Multiplier, and (ii) a fraction, the numerator of which is the
sum of the Extraordinary Dividend Amount and the market price on the Trading Day
preceding the ex-dividend date, and the denominator of which is the market price
on the Trading Day preceding the ex-dividend date. The "Extraordinary Dividend
Amount" with respect to an Extraordinary Dividend for a Portfolio Security will
equal such Extraordinary Dividend minus the amount of the immediately preceding
non-Extraordinary Dividend for such Portfolio Security.

  4. If the issuer of a Portfolio Security is being liquidated or is subject to
a proceeding under any applicable bankruptcy, insolvency or other similar law,
such Portfolio Security will continue to be included in the Portfolio so long as
a market price for such Portfolio Security is available. If a market price is no
longer available for a Portfolio Security for whatever reason, including the
liquidation of the issuer of such Portfolio Security or the subjection of the
issuer of such Portfolio Security to a proceeding under any applicable
bankruptcy, insolvency or other similar law, then the value of such Portfolio
Security will equal zero in connection with calculating the Portfolio Value and
the Ending Portfolio Value for so long as no market price is available, and no
attempt will be made to find a replacement stock or increase the value of the
Portfolio to compensate for the deletion of such Portfolio Security.

  5. If the issuer of a Portfolio Security has been subject to a merger or
consolidation and is not the surviving entity or is nationalized, then a value
for such Portfolio Security will be determined at the time such issuer is merged
or consolidated or nationalized and will equal the last available market price
for such Portfolio Security and that value will be constant for the remaining
term of the Securities. At such time, no adjustment will be made to the
Multiplier of such Portfolio Security. The Company may at its sole discretion
increase such last available market price to reflect payments or dividends of
cash, securities or other consideration to holders of such Portfolio Security in
connection with such a merger or consolidation which may not be reflected in
such last available market price.

  6. If the issuer of a Portfolio Security issues to all of its shareholders
equity securities that are publicly traded of an issuer other than the issuer of
the Portfolio Security, then such new equity securities will be added to the
Portfolio as a new Portfolio Security. The Multiplier for such new Portfolio
Security will equal the product of the

                                       14
<PAGE>
 
original Multiplier with respect to the Portfolio Security for which the new
Portfolio Security is being issued (the "Original Portfolio Security") and the
number of shares of the new Portfolio Security issued with respect to one share
of the Original Portfolio Security.

  No adjustments of any Multiplier of a Portfolio Security will be required
unless such adjustment would require a change of at least 1% in the Multiplier
then in effect. The Multiplier resulting from any of the adjustments specified
above will be rounded to the nearest one thousandth with five ten-thousandths
being rounded upward.

  The AMEX expects that no adjustments to the Multiplier of any Portfolio
Security or to the Portfolio will be made other than those specified above,
however, the AMEX may at its discretion make adjustments to maintain the
economic intent of the Portfolio.

  A potential investor should review the historical performance of the
Portfolio.  The historical performance of the Index should not be taken as an
indication of future performance, and no assurance can be given that the
Portfolio will increase sufficiently to cause the beneficial owners of the
Securities to receive an amount in excess of the principal amount at the
maturity of the Securities.

                                  OTHER TERMS

GENERAL

  The Securities were issued as a series of Senior Debt Securities under the
Indenture (the "Senior Indenture"), dated as of April 1, 1983, as amended and
restated, between the Company and The Chase Manhattan Bank, formerly known as
Chemical Bank (successor by merger to Manufacturers Hanover Trust Company), as
trustee (the "Trustee"). A copy of the Senior Indenture is filed as an exhibit
to the registration statements relating to the Securities. The following
summaries of certain provisions of the Senior Indenture do not purport to be
complete and are subject to, and qualified in their entirety by reference to,
all provisions of the Senior Indenture, including the definition therein of
certain terms.

  The Senior Indenture provides that series of Senior Debt Securities may from
time to time be issued thereunder, without limitation as to aggregate principal
amount, in one or more series and upon such terms as the Company may establish
pursuant to the provisions thereof.

  The Senior Indenture provides that the Senior Indenture and the Securities are
governed by and construed in accordance with the laws of the State of New York.

  The Senior Indenture provides that the Company may issue Senior Debt
Securities with terms different from those of Senior Debt Securities previously
issued, and "reopen" a previously issued series of Senior Debt Securities and
issue additional Senior Debt Securities of such series.

  The Senior Debt Securities are unsecured and rank pari passu with all other
unsecured and unsubordinated indebtedness of the Company.  However, since the
Company is a holding company, the right of the Company, and hence the right of
creditors of the Company (including the Holders of Senior Debt Securities), to
participate in any distribution of the assets of any subsidiary upon its
liquidation or reorganization or otherwise is necessarily subject to the prior
claims of creditors of the subsidiary, except to the extent that claims of the
Company itself as a creditor of the subsidiary may be recognized.  In addition,
dividends, loans and advances from certain subsidiaries, including MLPF&S, to
the Company are restricted by net capital requirements under the Exchange Act
and under rules of certain exchanges and other regulatory bodies.

                                       15
<PAGE>
 
LIMITATIONS UPON LIENS

  The Company may not, and may not permit any Subsidiary to, create, assume,
incur or permit to exist any indebtedness for borrowed money secured by a
pledge, lien or other encumbrance (except for certain liens specifically
permitted by the Senior Indenture) on the Voting Stock owned directly or
indirectly by the Company of any Subsidiary (other than a Subsidiary which, at
the time of the incurrence of such secured indebtedness, has a net worth of less
than $3,000,000) without making effective provision whereby the Outstanding
Senior Debt Securities will be secured equally and ratably with such secured
indebtedness.


LIMITATION ON DISPOSITION OF VOTING STOCK OF, AND MERGER AND SALE OF ASSETS BY,
MLPF&S

  The Indenture provides that the Company may not sell, transfer or otherwise
dispose of any Voting Stock of MLPF&S or permit MLPF&S to issue, sell or
otherwise dispose of any of its Voting Stock, unless, after giving effect to any
such transaction, MLPF&S remains a Controlled Subsidiary (defined in the Senior
Indenture to mean a corporation more than 80% of the outstanding shares of
Voting Stock of which are owned directly or indirectly by the Company).  In
addition, the Company may not permit MLPF&S to (i) merge or consolidate, unless
the surviving company is a Controlled Subsidiary or (ii) convey or transfer its
properties and assets substantially as an entirety, except to one or more
Controlled Subsidiaries.


MERGER AND CONSOLIDATION

  The Indenture provides that the Company may consolidate or merge with or into
any other corporation, and the Company may sell, lease or convey all or
substantially all of its assets to any corporation, provided that (i) the
corporation (if other than the Company) formed by or resulting from any such
consolidation or merger or which shall have received such assets shall be a
corporation organized and existing under the laws of the United States of
America or a state thereof and shall assume payment of the principal of (and
premium, if any) and interest on the Senior Debt Securities and the performance
and observance of all of the covenants and conditions of the Senior Indenture to
be performed or observed by the Company, and (ii) the Company or such successor
corporation, as the case may be, shall not immediately thereafter be in default
under the Senior Indenture.


MODIFICATION AND WAIVER

  Modification and amendment of the Indenture may be effected by the Company and
the Trustee with the consent of the Holders of 66 2/3% in principal amount of
the Outstanding Senior Debt Securities of each series issued pursuant to such
indenture and affected thereby, provided that no such modification or amendment
may, without the consent of the Holder of each Outstanding Senior Debt Security
affected thereby, (a) change the Stated Maturity of the principal of, or any
installment of interest or Additional Amounts payable on, any Senior Debt
Security or any premium payable on the redemption thereof, or change the
Redemption Price; (b) reduce the principal amount of, or the interest or
Additional Amounts payable on, any Senior Debt Security or reduce the amount of
principal which could be declared due and payable prior to the Stated Maturity;
(c) change place or currency of any payment of principal or any premium,
interest or Additional Amounts payable on any Senior Debt Security; (d) impair
the right to institute suit for the enforcement of any payment on or with
respect to any Senior Debt Security; (e) reduce the percentage in principal
amount of the Outstanding Senior Debt Securities of any series, the consent of
whose Holders is required to modify or amend the Indenture; or (f) modify the
foregoing requirements or reduce the percentage of Outstanding Senior Debt
Securities necessary to waive any past default to less than a majority.  No
modification or amendment of the Subordinated Indenture or any Subsequent
Indenture for Subordinated Debt Securities may adversely affect the rights of
any holder of Senior Indebtedness without the consent of such Holder.  Except
with respect to certain fundamental provisions, the Holders of at least a
majority in principal amount of Outstanding

                                       16
<PAGE>
 
Senior Debt Securities of any series may, with respect to such series, waive
past defaults under the Indenture and waive compliance by the Company with
certain provisions thereof.


EVENTS OF DEFAULT

  Under the Senior Indenture, the following will be Events of Default with
respect to Senior Debt Securities of any series: (a) default in the payment of
any interest or Additional Amounts payable on any Senior Debt Security of that
series when due, continued for 30 days; (b) default in the payment of any
principal or premium, if any, on any Senior Debt Security of that series when
due; (c) default in the deposit of any sinking fund payment, when due, in
respect of any Senior Debt Security of that series; (d) default in the
performance of any other covenant of the Company contained in the Indenture for
the benefit of such series or in the Senior Debt Securities of such series,
continued for 60 days after written notice as provided in the Senior Indenture;
(e) certain events in bankruptcy, insolvency or reorganization; and (f) any
other Event of Default provided with respect to Senior Debt Securities of that
series.  The Trustee or the Holders of 25% in principal amount of the
Outstanding Senior Debt Securities of that series may declare the principal
amount (or such lesser amount as may be provided for in the Senior Debt
Securities of that series) of all Outstanding Senior Debt Securities of that
series and the interest due thereon and Additional Amounts payable in respect
thereof, if any to be due and payable immediately if an Event of Default with
respect to Senior Debt Securities of such series shall occur and be continuing
at the time of such declaration.  At any time after a declaration of
acceleration has been made with respect to Senior Debt Securities of any series
but before a judgment or decree for payment of money due has been obtained by
the Trustee, the Holders of a majority in principal amount of the Outstanding
Senior Debt Securities of that series may rescind any declaration of
acceleration and its consequences, if all payments due (other than those due as
a result of acceleration) have been made and all Events of Default have been
remedied or waived.  Any Event of Default with respect to Senior Debt Securities
of any series may be waived by the Holders of a majority in principal amount of
all Outstanding Senior Debt Securities of that series, except in a case of
failure to pay principal or premium, if any, or interest or Additional Amounts
payable on any Senior Debt Security of that series for which payment had not
been subsequently made or in respect of a covenant or provision which cannot be
modified or amended without the consent of the Holder of each Outstanding Senior
Debt Security of such series affected.

  The Holders of a majority in principal amount of the Outstanding Senior Debt
Securities of a series may 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 Senior Debt Securities of such
series, provided that such direction shall not be in conflict with any rule of
law or the Senior Indenture.  Before proceeding to exercise any right or power
under the Senior Indenture at the direction of such Holders, the Trustee shall
be entitled to receive from such Holders reasonable security or indemnity
against the costs, expenses and liabilities which might be incurred by it in
complying with any such direction.

  The Company is required to furnish to the Trustee annually a statement as to
the fulfillment by the Company of all of its obligations under the Senior
Indenture.


            CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

  Solely for purposes of applying final Treasury regulations (the "Final
Regulations") concerning the United States Federal income tax treatment of
contingent payment debt instruments to the Securities, the Company has
determined that the projected payment schedule for the Securities will consist
of payment on the maturity date of the principal amount thereof and a
Supplemental Redemption Amount equal to $3.8425 per Unit. This represents an
estimated yield on the Securities equal to 6.61% per annum (compounded
semiannually).

  The projected payment schedule (including both the projected Supplemental
Redemption Amount and the estimated yield on the Securities) has been determined
solely for United States Federal income tax purposes (i.e.,

                                       17

for purposes of applying the Final Regulations to the Securities), and is not a
prediction of what the actual Supplemental Redemption Amount will be, or that
the actual Supplemental Redemption Amount will even exceed zero.

  The following table sets forth the amount of interest that will be deemed to
have accrued with respect to each Unit of the Securities during each accrual
period over the term of the Securities based upon the projected payment schedule
for the Securities (including both the projected Supplemental Redemption Amount
and the estimated yield equal to 6.61% per annum (compounded semiannually)) as
determined by the Company for purposes of the application of the Final
Regulations to the Securities:

debt expense, preferred stock dividend requirements of majority-owned
subsidiaries, and that portion of rentals estimated to be representative of the
interest factor.


                                  RISK FACTORS

  Your investment in MITTS will involve certain risks. For example, there is the
risk that you might not earn a return on your investment, and the risk that you
will be unable to sell your MITTS prior to their maturity. You should carefully
consider the following discussion of risks before deciding whether an investment
in the MITTS is suitable for you.

THE SUPPLEMENTAL REDEMPTION AMOUNT.

  You should be aware that if the Ending Index Value does not exceed the
Starting Index Value at maturity, the Supplemental Redemption Amount will be
zero. This will be true even if the value of the Index was higher than the
Starting Index Value at some time during the life of the MITTS but later falls
below the Starting Index Value. If the Supplemental Redemption Amount is zero,
we will pay you only the principal amount of your MITTS.

  The Participation Rate equals 140%. If the Ending Index Value exceeds the
Starting Index Value, then the Participation Rate will enhance the amount of the
interest payment received at maturity. However, if the Ending Index Value does
not exceed the Starting Index Value you will receive only the principal amount
of your MITTS.

YOUR YIELD MAY BE LOWER THAN THE YIELD ON A STANDARD DEBT SECURITY OF COMPARABLE
MATURITY.

  The amount we pay you at maturity may be less than the return you could earn
on other investments. Your yield may be less than the yield you would earn if
you bought a standard senior non-callable debt security of the Company with the
same maturity date. Your investment may not reflect the full opportunity cost to
you when you consider the effect of inflation or other factors that affect the
time value of money.

YOUR RETURN WILL NOT REFLECT THE PAYMENT OF DIVIDENDS.

  NKS calculates the Index by reference to the prices of the common stocks
comprising the Index without taking into consideration the value of dividends
paid on those stocks. Therefore, the return you earn on the MITTS, if any, will
not be the same as the return that you would earn if you actually owned each of
the common stocks in the Index and received the dividends paid on those stocks.

CURRENCY EXCHANGE RATE.

  Although the stocks comprising the Index are traded in Japanese yen and the
MITTS are denominated in U.S. dollars, we will not adjust the Supplemental
Redemption Amount for the currency exchange rate in effect at the maturity of
the MITTS. The Supplemental Redemption Amount is based solely upon the
percentage increase in the Index. Changes in the exchange rate, however, may
reflect changes in the Japanese economy which may affect the value of the Index
and the MITTS.

UNCERTAIN TRADING MARKET.

  The MITTS have been approved for listing on the New York Stock Exchange under
the symbol "JEM", subject to official notice of issuance. While there have been
a number of issuances of Market Index Target-Term Securities, trading volumes
have varied historically from one transaction to another and it is therefore
impossible to predict how the MITTS will trade. You cannot assume that a trading
market will develop for the MITTS. If such a trading market does develop, there
can be no assurance that there will be liquidity in the trading market. The
development of a trading market for the MITTS will depend on the financial
performance of the Company, and other factors such as the appreciation, if any,
of the value of the Index.

  If the trading market for the MITTS is limited, there may be a limited number
of buyers when you decide to sell your MITTS if you do not wish to hold your
investment until maturity. This may affect the price you receive.

FACTORS AFFECTING TRADING VALUE OF THE MITTS.

  We believe that the market value of the MITTS will be affected by the value of
the Index and by a number of other factors. Some of these factors are
interrelated in complex ways; as a result, the effect of any one factor may be
offset or magnified by the effect of

                                       3
<PAGE>
 
another factor. The following bullets describe the expected impact on the market
value of the MITTS given a change in a specific factor, assuming all other
conditions remain constant.

  .  Index Value. We expect that the market value of the MITTS will depend
  substantially on the amount by which the Index exceeds the Starting Index
  Value. If you choose to sell your MITTS when the value of the Index exceeds
  the Starting Index Value, you may receive substantially less than the amount
  that would be payable at maturity based on that Index value because of the
  expectation that the Index will continue to fluctuate until the Ending Index
  Value is determined. If you choose to sell your MITTS when the value of the
  Index is below the Starting Index Value, you may receive less than the $10
  principal amount per Unit of MITTS. In general, rising Japanese dividend rates
  (i.e., dividends per share) may increase the value of the Index while falling
  Japanese dividend rates may decrease the value of the Index. Political,
  economic and other developments that affect the stocks underlying the Index
  may also affect the value of the Index and the value of the MITTS.

  .  Interest Rates. Because the MITTS repay, at a minimum, the principal amount
  at maturity, we expect that the trading value of the MITTS will be affected by
  changes in interest rates. In general, if U.S. interest rates increase, we
  expect that the trading value of the MITTS will decrease. If U.S. interest
  rates decrease, we expect the trading value of the MITTS will increase. In
  general, if interest rates in Japan increase, we expect that the trading value
  of the MITTS will increase. If interest rates in Japan decrease, we expect the
  trading value of the MITTS will decrease. However, interest rates in Japan may
  also affect the Japanese economy and, in turn, the value of the Index. Rising
  interest rates in Japan may lower the value of the Index and the MITTS.
  Falling interest rates in Japan may increase the value of the Index and the
  value of the MITTS.

  .  Volatility of the Index. Volatility is the term used to describe the size
  and frequency of market fluctuations. If the volatility of the Index
  increases, we expect that the trading value of the MITTS will increase. If the
  volatility of the Index decreases, we expect that the trading value of the
  MITTS will decrease.

  .  Time Remaining to Maturity. The MITTS may trade at a value above that which
  would be expected based on the level of interest rates and the Index. This
  difference will reflect a "time premium" due to expectations concerning the
  value of the Index during the period prior to maturity of the MITTS. However,
  as the time remaining to maturity of the MITTS decreases, we expect that this
  time premium will decrease, lowering the trading value of the MITTS.

  .  Dividend Yields. If dividend yields on the stocks comprising the Index
  increase, we expect that the value of the MITTS will decrease. Conversely, if
  dividend yields on the stocks comprising the Index decrease, we expect that
  the value of the MITTS will increase.

  .  Company Credit Ratings. Real or anticipated changes in the Company's credit
  ratings may affect the market value of the MITTS.

  We want you to understand that the impact of one of the factors specified
above, such as an increase in interest rates, may offset some or all of any
change in the trading value of the MITTS attributable to another factor, such as
an increase in the Index value.

  In general, assuming all relevant factors are held constant, we expect that
the effect on the trading value of the MITTS of a given change in most of the
factors listed above will be less if it occurs later in the term of the MITTS
than if it occurs earlier in the term of the MITTS except that we expect that
the effect on the trading value of the MITTS of a given increase in the value of
the Index will be greater if it occurs later in the term of the MITTS than if it
occurs earlier in the term of the MITTS.

STATE LAW LIMITS ON INTEREST PAID.

  New York State laws govern the 1983 Indenture. New York has certain usury laws
that limit the amount of interest that can be charged and paid on loans, which
includes debt securities like the MITTS. Under present New York law, the maximum
rate of interest is 25% per annum on a simple interest basis. This limit may not
apply to debt securities in which $2,500,000 or more has been invested.

  While we believe that New York law would be given effect by a state or Federal
court sitting outside of New York, many other states also have laws that
regulate the amount of interest that may be charged to and paid by a borrower.
We will promise, for the benefit of the MITTS holders, to the extent permitted
by law, not to voluntarily claim the benefits of any laws concerning usurious
rates of interest.

THE JAPANESE SECURITIES MARKET.

  The underlying stocks that constitute the Index have been issued by Japanese
companies. You should be aware that investments in securities indexed to the
value of Japanese equity securities involve certain risks. The Japanese
securities markets may be more volatile than U.S. or other securities markets
and may be affected by market developments in different ways than U.S. or other
securities markets. Direct or indirect government intervention to stabilize the
Japanese securities markets and cross-shareholdings in Japanese companies on
such markets may affect prices and volume of trading on those markets. Also,
there is generally less publicly available information about Japanese companies
than about those U.S. companies that are subject to the reporting requirements
of the U.S. Securities and Exchange Commission, and Japanese companies are
subject to accounting, auditing and financial reporting standards and
requirements that differ from those applicable to U.S. reporting companies.

  Securities prices in Japan are subject to political, economic, financial and
social factors that apply in Japan. These factors (including the possibility
that recent or future changes in the Japanese government's economic and fiscal
policies, the possible imposition of, or changes in, currency exchange laws or
other Japanese laws or restrictions applicable to Japanese companies or
investments in Japanese equity securities and the possibility of fluctuations in
the rate of exchange between currencies) could negatively affect the Japanese
securities markets. Moreover, the Japanese economy may differ favorably or
unfavorably from the U.S. economy in such respects as growth of gross national
product, rate of inflation, capital reinvestment, resources and self-
sufficiency.

PURCHASES AND SALES BY MERRILL LYNCH.

  The Company, MLPF&S, and other affiliates of the Company may from time to time
buy or sell the stocks underlying the Index for their own accounts for business
reasons or in connection with hedging the Company's obligations under the MITTS.
These transactions could affect the price of such stocks and the value of the
Index.

POTENTIAL CONFLICTS.

  Under certain circumstances, MLPF&S's roles as a subsidiary of the Company, a
counterparty of the Company's hedge, the Underwriter and the Calculation Agent
for the MITTS could give rise to conflicts of interests.


                           DESCRIPTION OF SECURITIES

GENERAL

  The Nikkei 225 Market Index Target-Term Securities due June 14, 2002, which
are referred to herein as the "MITTS" or the "Securities", are to be issued as a
series of Senior Debt Securities under the Senior Indenture, referred to as the
"1983 Indenture", which is more fully described in the accompanying Prospectus.
The Securities will mature on June 14, 2002.

  While at maturity a beneficial owner of a Security will receive the principal
amount of such Security plus the Supplemental Redemption Amount, if any, there
will be no other payment of interest, periodic or otherwise. See "Payment at
Maturity" below.

  The Securities are not subject to redemption by the Company or at the option
of any beneficial owner prior to maturity. Upon the occurrence of an Event of
Default with respect to the Securities, beneficial owners of the Securities may
accelerate the maturity of the Securities, as described under "Description of
Securities -- Events of Default and Acceleration" in this Prospectus Supplement
and "Description of Debt Securities -- General -- Events of Default" in the
accompanying Prospectus.

  The Securities are to be issued in denominations of whole Units.

PAYMENT AT MATURITY

General

  At maturity, a beneficial owner of a Security will be entitled to receive the
principal amount thereof plus a Supplemental Redemption Amount, if any, as
provided below. If the Ending Index Value does not exceed the Starting Index
Value, a beneficial owner of a Security will be entitled to receive only the
principal amount thereof. The principal amount for a Security will equal the
initial issue price of $10 per Unit of MITTS.

Determination of the Supplemental Redemption Amount

  The Supplemental Redemption Amount for a Security will be determined by the
Calculation Agent and will equal:

<TABLE> 
  <S>                                                  <C> 
  Principal Amount of such Security ($10 per Unit)  X  Ending Index Value -- Starting Index Value  X Participation Rate
                                                       ------------------------------------------                      
                                                              Starting Index Value
</TABLE> 

provided, however, that in no event will the Supplemental Redemption Amount be
less than zero. As indicated in the formula above, the Supplemental Redemption
Amount for the MITTS will be calculated using the principal amount of the MITTS.

  The Participation Rate equals 140%. The Starting Index Value equals 20,351.34,
which was the closing value of the Index on the Pricing Date.  The Ending Index
Value will be determined by the Calculation Agent and will equal the average
(arithmetic mean) of the closing values of the Index determined on each of the
first five Calculation Days during the Calculation Period. If there are fewer
than five Calculation Days, then the Ending Index Value will equal the average
(arithmetic mean) of the closing values of the Index on such Calculation Days,
and if there is only one Calculation Day, then the Ending Index Value will equal
the closing value of the Index on such Calculation Day. If no Calculation Days
occur during the Calculation Period because of Market Disruption Events, then
the Ending Index Value will equal the closing value of the Index determined on
the last scheduled Index Business Day in the Calculation Period, regardless of
the occurrence of a Market Disruption Event on such day. The "Calculation
Period" means the period from and including the seventh scheduled Index Business
Day prior to the maturity date to and including the second scheduled Index
Business Day prior to the maturity date. "Calculation Day" means any Index
Business Day during the Calculation Period on which a Market Disruption Event
has not occurred. For purposes of determining the Ending Index Value, an "Index
Business Day" is a day on which the New York Stock Exchange and the American
Stock Exchange are open for trading and the Index or any Successor Index, as
defined below, is calculated and published. All determinations made by the
Calculation Agent shall be at the sole discretion of the Calculation Agent and,
absent a

                                       5
<PAGE>
 
determination by the Calculation Agent of a manifest error, shall be conclusive
for all purposes and binding on the Company and beneficial owners of the
Securities.

HYPOTHETICAL RETURNS

  The following table illustrates, for a range of hypothetical Ending Index
Values, (i) the total amount payable at maturity for each $10 principal amount
of Securities, (ii) the total rate of return to beneficial owners of the
Securities, (iii) the pretax annualized rate of return to beneficial owners of
Securities, and (iv) the pretax annualized rate of return of an investment in
the stocks underlying the Index (which includes an assumed aggregate dividend
yield of .75% per annum, as more fully described below).

___________

(1) The annualized rates of return specified in the preceding table are
calculated on a semiannual bond equivalent basis.

(2) This rate of return assumes (i) an investment of a fixed amount in the
stocks underlying the Index with the allocation of such amount reflecting the
current relative weights of such stocks in the Index; (ii) a percentage change
in the aggregate price of such stocks that equals the percentage change in the
Index from the Starting Index Value to the relevant hypothetical Ending Index
Value; (iii) a constant dividend yield of .75% per annum, paid quarterly from
the date of initial delivery of Securities, applied to the value of the Index at
the end of each such quarter assuming such value increases or decreases linearly
from the Starting Index Value to the applicable hypothetical Ending Index Value;
(iv) no transaction fees or expenses; (v) a term for the Securities from June 3,
1997 to June 14, 2002; and (vi) a final Index value equal to the Ending Index
Value. The aggregate dividend yield of the stocks underlying the Index as of May
28, 1997 was approximately .75%.

(3) This is the Starting Index Value.

  The above figures are for purposes of illustration only. The actual
Supplemental Redemption Amount received by investors and the total and pretax
annualized rate of return resulting therefrom will depend entirely on the actual
Ending Index Value determined by the Calculation Agent as provided herein.
Historical data regarding the Index is included in this Prospectus Supplement
under "The Index -- Historical Data on the Index".

ADJUSTMENTS TO THE INDEX; MARKET DISRUPTION EVENTS

  If at any time the method of calculating the Index, or the value thereof, is
changed in any material respect, or if the Index is in any other way modified so
that such Index does not, in the opinion of the Calculation Agent, fairly
represent the value of the Index had such changes or modifications not been
made, then, from and after such time, the Calculation Agent shall, at the close
of business in New York, New York, on each date that the closing value with
respect to the Ending Index Value is to be calculated, make such adjustments as,
in the good faith judgment of the Calculation Agent, may be necessary in order
to arrive at a calculation of a value of a stock index comparable to the Index
as if such changes or modifications had not been made, and calculate such
closing value with reference to the Index, as adjusted. Accordingly, if the
method of calculating the Index is modified so that the value of such Index is a
fraction or a multiple of what it would have been if it had not been modified
(e.g., due to a split in the Index), then the Calculation Agent shall adjust
such Index in order to arrive at a value of the Index as if it had not been
modified (e.g., as if such split had not occurred).

                                       6
<PAGE>
 
  "Market Disruption Event" means either of the following events, as determined
by the Calculation Agent: (a)a suspension, material limitation or absence of
trading on the TSE of 20% or more of the Underlying Stocks which then comprise
the Index or a Successor Index during the one-half hour period preceding the
close of trading on the applicable exchange; or (b)the suspension or material
limitation on the Singapore International Monetary Exchange, Ltd. (the "SIMEX"),
the Osaka Securities Exchange (the "OSE") or any other major futures or
securities market from trading in futures or options contracts related to the
Index or a Successor Index during the one-half hour period preceding the close
of trading on the applicable exchange.

  For the purposes of determining whether a Market Disruption Event has
occurred: (i) a limitation on the hours or number of days of trading will not
constitute a Market Disruption Event if it results from an announced change in
the regular business hours of the relevant exchange, (ii) a decision to
permanently discontinue trading in the relevant futures or options contract will
not constitute a Market Disruption Event, (iii) a suspension in trading in a
futures or options contract on the Index by a major securities market by reason
of (a) a price change violating limits set by such securities market, (b) an
imbalance of orders relating to such contracts or (c) a disparity in bid and ask
quotes relating to such contracts will constitute a suspension or material
limitation of trading in futures or options contracts related to the Index, and,
(iv) an absence of trading on the TSE will not include any time when the TSE is
closed for trading under ordinary circumstances. Under certain circumstances,
the duties of MLPF&S as Calculation Agent in determining the existence of Market
Disruption Events could conflict with the interests of MLPF&S as an affiliate of
the issuer of the MITTS.

  Based on the information currently available to the Company, the opening of
trading on the OSE was delayed on January 17, 1995 because of the earthquake in
Kobe. If such delay had occurred during the one-half hour period preceding the
close of trading on the OSE, it would have constituted a Market Disruption
Event. In addition, because of movements in the price for futures contracts for
the Index, the OSE imposed price limits on such futures contracts on January 23,
1995 that were in effect during the one-half hour period preceding the close of
trading on the OSE and that would have constituted a Market Disruption Event. On
January 31 and February 1 of 1994, prices for futures contracts for the Nikkei
Stock Index 225 reached price limits imposed by the OSE, which would have been a
Market Disruption Event. Other than the foregoing events, to the Company's
knowledge no circumstances have arisen since the inception of the Index that
could have constituted a Market Disruption Event. The existence or non-existence
of such circumstances, however, is not necessarily indicative of the likelihood
of such circumstances arising or not arising in the future.

DISCONTINUANCE OF THE INDEX

  If NKS discontinues publication of the Index and NKS or another entity
publishes a successor or substitute index that the Calculation Agent determines,
in its sole discretion, to be comparable to such Index (any such index being
referred to hereinafter as a "Successor Index"), then, upon the Calculation
Agent's notification of such determination to the Trustee and the Company, the
Calculation Agent will substitute the Successor Index as calculated by NKS or
such other entity for the Index and calculate the Ending Index Value as
described above under "Payment at Maturity". Upon any selection by the
Calculation Agent of a Successor Index, the Company shall cause notice thereof
to be given to Holders of the Securities.

  If NKS discontinues publication of the Index and a Successor Index is not
selected by the Calculation Agent or is no longer published on any of the
Calculation Days, the value to be substituted for the Index for any such
Calculation Day used to calculate the Supplemental Redemption Amount at maturity
will be a value computed by the Calculation Agent for each Calculation Day in
accordance with the procedures last used to calculate the Index prior to any
such discontinuance. If a Successor Index is selected or the Calculation Agent
calculates a value as a substitute for the Index as described below, such
Successor Index or value shall be substituted for the Index for all purposes,
including for purposes of determining whether a Market Disruption Event exists.

  If NKS discontinues publication of the Index prior to the period during which
the Supplemental Redemption Amount is to be determined and the Calculation Agent
determines that no Successor Index is available at such time, then on each
Business Day until the earlier to occur of (a) the determination of the Ending
Index Value and (b) a determination by the Calculation Agent that a Successor
Index is available, the Calculation Agent shall determine the value that would
be used in computing the Supplemental Redemption Amount as described in the
preceding paragraph as if such day were a Calculation Day. The Calculation Agent
will cause notice of each such value to be published not less often than once
each month in The Wall Street Journal (or another newspaper of general
circulation), and arrange for information with respect to such values to be made
available by telephone. Notwithstanding these alternative arrangements,
discontinuance of the publication of the Index may adversely affect trading in
the Securities.

EVENTS OF DEFAULT AND ACCELERATION

  In case an Event of Default with respect to any Securities shall have occurred
and be continuing, the amount payable to a beneficial owner of a Security upon
any acceleration permitted by the Securities, with respect to each $10 principal
amount thereof, will be equal to the principal amount and the Supplemental
Redemption Amount, if any, calculated as though the date of early repayment were
the stated maturity date of the Securities. See "Description of Securities --
Payment at Maturity" in this Prospectus Supplement. If a bankruptcy proceeding
is commenced in respect of the Company, the claim of the beneficial owner of a
Security may be limited, under Section 502(b)(2) of Title 11 of the United
States Code, to the principal amount of the Security plus an additional amount
of contingent interest calculated as though the date of the commencement of the
proceeding were the maturity date of the Securities.

  In case of default in payment at the maturity date of the Securities (whether
at their stated maturity or upon acceleration), from and after the maturity date
the Securities shall bear interest, payable upon demand of the beneficial owners
thereof, at the rate of 6.96% per annum (to the extent that payment of such
interest shall be legally enforceable) on the unpaid amount due and payable on
such date in accordance with the terms of the Securities to the date payment of
such amount has been made or duly provided for.

DEPOSITORY

  Upon issuance, all Securities will be represented by one or more fully
registered global securities (the "Global Securities"). Each such Global
Security will be deposited with, or on behalf of, The Depository Trust Company
("DTC"), as Depository, registered in the name of DTC or a nominee thereof.
Unless and until it is exchanged in whole or in part for Securities in
definitive form, no Global Security may be transferred except as a whole by the
Depository to a nominee of such Depository or by a nominee of such Depository to
such Depository or another nominee of such Depository or by such Depository or
any such nominee to a successor of such Depository or a nominee of such
successor.

  DTC has advised the Company as follows: DTC is a limited-purpose trust company
organized under the Banking Law of the State of New York, a member of the
Federal Reserve System, a "clearing corporation" within the meaning of the New
York Uniform Commercial Code, and a "clearing agency" registered pursuant to the
provisions of Section 17A of the Securities Exchange Act of 1934, as amended.
DTC was created to hold securities of its participants ("Participants") and to
facilitate the clearance and settlement of securities transactions among its
Participants in such securities through electronic book-entry changes in
accounts of the Participants, thereby eliminating the need for physical movement
of securities certificates. DTC's Participants include securities brokers and
dealers, banks, trust companies, clearing corporations, and certain other
organizations.

  DTC is owned by a number of Participants and by the New York Stock Exchange,
Inc., the American Stock Exchange, Inc. and the National Association of
Securities Dealers, Inc. Access to the DTC book-entry system is also available
to others, such as banks, brokers, dealers and trust companies that clear
through or maintain a custodial relationship with a Participant, either directly
or indirectly ("Indirect Participants").

  Purchases of Securities must be made by or through Participants, which will
receive a credit on the records of DTC. The ownership interest of each actual
purchaser of each Security ("Beneficial Owner") is in turn to be recorded on the
Participants' or Indirect Participants' records. Beneficial Owners will not
receive written confirmation from DTC of their purchase, but Beneficial Owners
are expected to receive written confirmations providing details of the
transaction, as well as periodic statements of their holdings, from the
Participant or Indirect Participant through which the Beneficial Owner entered
into the transaction. Ownership of beneficial interests in such Global Security
will be shown on, and the transfer of such ownership interests will be effected
only through, records maintained by DTC (with respect to interests of
Participants) and on the records of Participants (with respect to interests of
persons held through Participants). The laws of some states may require that
certain purchasers of securities take physical delivery of such securities in
definitive form. Such limits and such laws may impair the ability to own,
transfer or pledge beneficial interests in Global Securities.

  So long as DTC, or its nominee, is the registered owner of a Global Security,
DTC or its nominee, as the case may be, will be considered the sole owner or
Holder of the Securities represented by such Global Security for all purposes
under the 1983 Indenture. Except as provided below, Beneficial Owners in a
Global Security will not be entitled to have the Securities represented by such
Global Securities registered in their names, will not receive or be entitled to
receive physical delivery of the Securities in definitive form and will not be
considered the owners or Holders thereof under the 1983 Indenture, including for
purposes of receiving any reports delivered by the Company or the Trustee
pursuant to the 1983 Indenture. Accordingly, each Person owning a beneficial
interest in a Global Security must rely on the procedures of DTC and, if such
Person is not a Participant, on the procedures of the Participant through which
such Person owns its interest, to exercise any rights of a Holder under the 1983
Indenture. The Company understands that under existing industry practices, in
the event that the Company requests any action of Holders or that an owner of a
beneficial interest in such a Global Security desires to give or take any action
which a Holder is entitled to give or take under the 1983 Indenture, DTC would
authorize the Participants holding the relevant beneficial interests to give or
take such action, and such Participants would authorize Beneficial Owners owning
through such Participants to give or take such action or would otherwise act
upon the instructions of Beneficial Owners. Conveyance of notices and other
communications by DTC to Participants, by Participants to Indirect Participants,
and by Participants and Indirect Participants to Beneficial Owners will be
governed by arrangements among them, subject to any statutory or regulatory
requirements as may be in effect from time to time.

  Payment of the principal amount and any Supplemental Redemption Amount with
respect to the Securities registered in the name of DTC or its nominee will be
made to DTC or its nominee, as the case may be, as the Holder of the Global
Securities representing such Securities. None of the Company, the Trustee or any
other agent of the Company or agent of the Trustee will have any responsibility
or liability for any aspect of the records relating to or payments made on
account of beneficial ownership interests or for supervising or reviewing any
records relating to such beneficial ownership interests. The Company expects
that DTC, upon receipt of any payment of principal or any Supplemental
Redemption Amount in respect of a Global Security, will credit the accounts of
the Participants with payment in amounts proportionate to their respective
holdings in principal amount of beneficial interest in such Global Security as
shown on the records of DTC. The Company also expects that payments by
Participants to Beneficial Owners will be governed by standing customer
instructions and customary practices, as is now the case with securities held
for the accounts of customers in bearer form or registered in "street name", and
will be the responsibility of such Participants.

  If (x) any Depository is at any time unwilling or unable to continue as
Depository and a successor depository is not appointed by the Company within 60
days, (y) the Company executes and delivers to the Trustee a Company Order to
the effect that the Global Securities shall be exchangeable or (z) an Event of
Default has occurred and is continuing with respect to the Securities, the
Global Securities will be exchangeable for Securities in definitive form of like
tenor and of an equal aggregate principal amount, in denominations of $10 and
integral multiples thereof. Such definitive Securities shall be registered in
such name or names as the Depository shall instruct the Trustee. It is expected
that such instructions may be based upon directions received by the Depository
from Participants with respect to ownership of beneficial interests in such
Global Securities.

SAME-DAY SETTLEMENT AND PAYMENT

  Settlement for the Securities will be made by the underwriter in immediately
available funds. All payments of principal and the Supplemental Redemption
Amount, if any, will be made by the Company in immediately available funds so
long as the Securities are maintained in book-entry form.

                                   THE INDEX

  All disclosure contained in this Prospectus Supplement regarding the Index,
including, without limitation, its make-up, method of calculation and changes in
its components, is derived from publicly available information prepared by Nihon
Keizai Shimbun, Inc. ("NKS").

GENERAL

  Unless otherwise stated, all information herein relating to the Nikkei 225
Index has been derived from the Stock Market Indices Data Book published by NKS
and other publicly-available sources. Such information reflects the policies of
NKS as stated in such sources; such policies are subject to change at the
discretion of NKS.

  The Nikkei 225 Index is a stock index calculated, published and disseminated
by NKS that measures the composite price performance of selected Japanese
stocks. The Nikkei 225 Index is currently based on 225 Underlying Stocks trading
on the TSE and represents a broad cross-section of Japanese industry. All 225
Underlying Stocks are stocks listed in the First Section of the TSE. Stocks
listed in the First Section are among the most actively traded stocks on the
TSE. Futures and options contracts on the Nikkei 225 Index are traded on the
Singapore International Monetary Exchange Ltd., the Osaka Securities Exchange
and the Chicago Mercantile Exchange.

  The Nikkei 225 Index is a modified, price-weighted index (i.e., an Underlying
Stock's weight in the index is based on its price per share rather than the
total market capitalization of the issuer) which is calculated by (i)
multiplying the per share price of each Underlying Stock by the corresponding
weighting factor for such Underlying Stock (a "Weight Factor"), (ii) calculating
the sum of all these products and (iii) dividing such sum by a divisor. The
divisor, initially set in 1949 at 225, was 9.999 as of May 28, 1997, and is
subject to periodic adjustments as set forth below. Each Weight Factor is
computed by dividing (Yen)50 by the par value of the relevant Underlying Stock,
so that the share price of each Underlying Stock when multiplied by its Weight
Factor corresponds to a share price based on a uniform par value of (Yen)50.
Each Weight Factor represents the number of shares of the related Underlying
Stock which are included in one trading unit of the Nikkei 225 Index. The stock
prices used in the calculation of the Nikkei 225 Index are those reported by a
primary market for the Underlying Stocks (currently the TSE). The level of the
Nikkei 225 Index is calculated once per minute during TSE trading hours.

  In order to maintain continuity in the level of the Nikkei 225 Index in the
event of certain changes due to non-market factors affecting the Underlying
Stocks, such as the addition or deletion of stocks, substitution of stocks,
stock dividends, stock splits or distributions of assets to stockholders, the
divisor used in calculating the Nikkei 225 Index is adjusted in a manner
designed to prevent any instantaneous change or discontinuity in the level of
the Nikkei 225 Index. Thereafter, the divisor remains at the new value until a
further adjustment is necessary as the result of another change. As a result of
each such change affecting any Underlying Stock, the divisor is adjusted in such
a way that the sum of all share prices immediately after such change multiplied
by the applicable Weight Factor and divided by the new divisor (i.e., the level
of the Nikkei 225 Index immediately after such change) will equal the level of
the Nikkei 225 Index immediately prior to the change.

  Underlying Stocks may be deleted or added by NKS. However, to maintain
continuity in the Nikkei 225 Index, the policy of NKS is generally not to alter
the composition of the Underlying Stocks except when an Underlying Stock is
deleted in accordance with the following criteria. Any stock becoming ineligible
for listing in the First Section of the TSE due to any of the following reasons
will be deleted from the Underlying Stocks: bankruptcy of the issuer; merger of
the issuer into, or acquisition of the issuer by, another company; delisting of
such stock or transfer of such stock to the "Seiri-Post" because of excess debt
of the issuer or because of any other reason; or transfer of such stock to the
Second Section of the TSE. Upon deletion of a stock from the Underlying Stocks,
NKS will select, in accordance with certain criteria established by it, a
replacement for such deleted Underlying Stock. In an exceptional case, a newly
listed stock in the First Section of the TSE that is recognized by NKS to be
representative of a market may be added to the Underlying Stocks. In such case,
an existing Underlying Stock with low trading volume and not representative of a
market will be deleted.

  NKS is under no obligation to continue the calculation and dissemination of
the Nikkei 225 Index. The MITTS are not sponsored, endorsed, sold or promoted by
NKS. No inference should be drawn from the information contained in this
Prospectus Supplement that NKS makes any representation or warranty, implied or
express, to the Company, the holders of the MITTS or any member of the public
regarding the advisability of investing in securities generally or in the MITTS
in particular or the ability of the Nikkei 225 Index to track general stock
market performance. NKS has no obligation to take the needs of the Company or
the holders of the MITTS into consideration in determining, composing or
calculating the Nikkei 225 Index. NKS is not responsible for, and has not
participated in the determination of the timing of, prices for, or quantities
of, the MITTS to be issued or in the determination or calculation of the
equation by which the MITTS are to be settled in cash. NKS has no obligation or
liability in connection with the administration, marketing or trading of the
MITTS.

  The use of and reference to the Nikkei 225 Index in connection with the MITTS
have been consented to by NKS, the publisher of the Nikkei 225 Index.

  None of the Company, the Calculation Agent and the Underwriter accepts any
responsibility for the calculation, maintenance or publication of the Nikkei 225
Index or any Successor Index. NKS disclaims all responsibility for any errors or
omissions in the

                                       9

calculation and dissemination of the Nikkei 225 Index or the manner in which
such Index is applied in determining any Starting or Ending Index Values or any
Supplemental Redemption Amount upon maturity of the MITTS.

THE TOKYO STOCK EXCHANGE

  The Tokyo Stock Exchange is one of the world's largest securities exchanges in
terms of market capitalization. The TSE market is a two-way, continuous pure
auction market. Trading hours are currently from 9:00 A.M. to 11:00 A.M. and
from 12:30 P.M. to 3:00 P.M., Tokyo time, Monday through Friday.

  Due to the time zone difference, on any normal trading day the TSE will close
prior to the opening of business in New York City on the same calendar day.
Therefore, the closing level of the Nikkei 225 Index on such trading day will
generally be available in the United States by the opening of business on the
same calendar day.

  The TSE has adopted certain measures, including daily price floors and
ceilings on individual stocks, intended to prevent any extreme short-term price
fluctuations resulting from order imbalances. In general, any stock listed on
the TSE cannot be traded at a price lower than the applicable price floor or
higher than the applicable price ceiling. Such price floors and ceilings are
expressed in absolute Japanese yen, rather than percentage, limits based on the
closing price of the stock on the previous trading day. In addition, when there
is a major order imbalance in a listed stock, the TSE posts a "special bid
quote" or a "special asked quote" for that stock at a specified higher or lower
price level than the stock's last sale price in order to solicit counter-orders
and balance supply and demand for the stock. Investors should also be aware that
the TSE may suspend the trading of individual stocks in certain limited and
extraordinary circumstances, including, for example, unusual trading activity in
that stock. As a result, changes in the Nikkei 225 Index may be limited by price
limitations or special quotes, or by suspension of trading, on individual stocks
which comprise the Nikkei 225 Index, which limitations may, in turn, adversely
affect the value of the MITTS.


                                  OTHER TERMS
GENERAL

  The Securities were issued as a series of Senior Debt Securities under the
Indenture (the "Senior Indenture"), dated as of April 1, 1983, as amended and
restated, between the Company and The Chase Manhattan Bank, formerly known as
Chemical Bank (successor by merger to Manufacturers Hanover Trust Company), as
trustee (the "Trustee"). A copy of the Senior Indenture is filed as an exhibit
to the registration statements relating to the Securities. The following
summaries of certain provisions of the Senior Indenture do not purport to be
complete and are subject to, and qualified in their entirety by reference to,
all provisions of the Senior Indenture, including the definition therein of
certain terms.

  The Senior Indenture provides that series of Senior Debt Securities may from
time to time be issued thereunder, without limitation as to aggregate principal
amount, in one or more series and upon such terms as the Company may establish
pursuant to the provisions thereof.

  The Senior Indenture provides that the Senior Indenture and the Securities are
governed by and construed in accordance with the laws of the State of New York.

  The Senior Indenture provides that the Company may issue Senior Debt
Securities with terms different from those of Senior Debt Securities previously
issued, and "reopen" a previously issued series of Senior Debt Securities and
issue additional Senior Debt Securities of such series.

  The Senior Debt Securities are unsecured and rank pari passu with all other
unsecured and unsubordinated indebtedness of the Company.  However, since the
Company is a holding company, the right of the Company, and hence the right of
creditors of the Company (including the Holders of Senior Debt Securities), to
participate in any distribution of the assets of any subsidiary upon its
liquidation or reorganization or otherwise is necessarily subject to the prior
claims of creditors of the subsidiary, except to the extent that claims of the
Company itself as a creditor of the subsidiary may be recognized.  In addition,
dividends, loans and advances from certain subsidiaries, including MLPF&S, to
the Company are restricted by net capital requirements under the Exchange Act
and under rules of certain exchanges and other regulatory bodies.

LIMITATIONS UPON LIENS

  The Company may not, and may not permit any Subsidiary to, create, assume,
incur or permit to exist any indebtedness for borrowed money secured by a
pledge, lien or other encumbrance (except for certain liens specifically
permitted by the Senior Indenture) on the Voting Stock owned directly or
indirectly by the Company of any Subsidiary (other than a Subsidiary which, at
the time of the incurrence of such secured indebtedness, has a net worth of less
than $3,000,000) without making effective provision whereby the Outstanding
Senior Debt Securities will be secured equally and ratably with such secured
indebtedness.

LIMITATION ON DISPOSITION OF VOTING STOCK OF, AND MERGER AND SALE OF ASSETS BY,
MLPF&S

  The Indenture provides that the Company may not sell, transfer or otherwise
dispose of any Voting Stock of MLPF&S or permit MLPF&S to issue, sell or
otherwise dispose of any of its Voting Stock, unless, after giving effect to any
such transaction, MLPF&S remains a Controlled Subsidiary (defined in the Senior
Indenture to mean a corporation more than 80% of the outstanding shares of
Voting Stock of which are owned directly or indirectly by the Company).  In
addition, the Company may not permit MLPF&S to (i) merge or consolidate, unless
the surviving company is a Controlled Subsidiary or (ii) convey or transfer its
properties and assets substantially as an entirety, except to one or more
Controlled Subsidiaries.

                                       10
<PAGE>
 
MERGER AND CONSOLIDATION

  The Indenture provides that the Company may consolidate or merge with or into
any other corporation, and the Company may sell, lease or convey all or
substantially all of its assets to any corporation, provided that (i) the
corporation (if other than the Company) formed by or resulting from any such
consolidation or merger or which shall have received such assets shall be a
corporation organized and existing under the laws of the United States of
America or a state thereof and shall assume payment of the principal of (and
premium, if any) and interest on the Senior Debt Securities and the performance
and observance of all of the covenants and conditions of the Senior Indenture to
be performed or observed by the Company, and (ii) the Company or such successor
corporation, as the case may be, shall not immediately thereafter be in default
under the Senior Indenture.

MODIFICATION AND WAIVER

  Modification and amendment of the Indenture may be effected by the Company and
the Trustee with the consent of the Holders of 66 2/3% in principal amount of
the Outstanding Senior Debt Securities of each series issued pursuant to such
indenture and affected thereby, provided that no such modification or amendment
may, without the consent of the Holder of each Outstanding Senior Debt Security
affected thereby, (a) change the Stated Maturity of the principal of, or any
installment of interest or Additional Amounts payable on, any Senior Debt
Security or any premium payable on the redemption thereof, or change the
Redemption Price; (b) reduce the principal amount of, or the interest or
Additional Amounts payable on, any Senior Debt Security or reduce the amount of
principal which could be declared due and payable prior to the Stated Maturity;
(c) change place or currency of any payment of principal or any premium,
interest or Additional Amounts payable on any Senior Debt Security; (d) impair
the right to institute suit for the enforcement of any payment on or with
respect to any Senior Debt Security; (e) reduce the percentage in principal
amount of the Outstanding Senior Debt Securities of any series, the consent of
whose Holders is required to modify or amend the Indenture; or (f) modify the
foregoing requirements or reduce the percentage of Outstanding Senior Debt
Securities necessary to waive any past default to less than a majority.  No
modification or amendment of the Subordinated Indenture or any Subsequent
Indenture for Subordinated Debt Securities may adversely affect the rights of
any holder of Senior Indebtedness without the consent of such Holder.  Except
with respect to certain fundamental provisions, the Holders of at least a
majority in principal amount of Outstanding Senior Debt Securities of any series
may, with respect to such series, waive past defaults under the Indenture and
waive compliance by the Company with certain provisions thereof.

EVENTS OF DEFAULT

  Under the Senior Indenture, the following will be Events of Default with
respect to Senior Debt Securities of any series: (a) default in the payment of
any interest or Additional Amounts payable on any Senior Debt Security of that
series when due, continued for 30 days; (b) default in the payment of any
principal or premium, if any, on any Senior Debt Security of that series when
due; (c) default in the deposit of any sinking fund payment, when due, in
respect of any Senior Debt Security of that series; (d) default in the
performance of any other covenant of the Company contained in the Indenture for
the benefit of such series or in the Senior Debt Securities of such series,
continued for 60 days after written notice as provided in the Senior Indenture;
(e) certain events in bankruptcy, insolvency or reorganization; and (f) any
other Event of Default provided with respect to Senior Debt Securities of that
series.  The Trustee or the Holders of 25% in principal amount of the
Outstanding Senior Debt Securities of that series may declare the principal
amount (or such lesser amount as may be provided for in the Senior Debt
Securities of that series) of all Outstanding Senior Debt Securities of that
series and the interest due thereon and Additional Amounts payable in respect
thereof, if any to be due and payable immediately if an Event of Default with
respect to Senior Debt Securities of such series shall occur and be continuing
at the time of such declaration.  At any time after a declaration of
acceleration has been made with respect to Senior Debt Securities of any series
but before a judgment or decree for payment of money due has been obtained by
the Trustee, the Holders of a majority in principal amount of the Outstanding
Senior Debt Securities of that series may rescind any declaration of
acceleration and its consequences, if all payments due (other than those due as
a result of acceleration) have been made and all Events of Default have been
remedied or waived.  Any Event of Default with respect to Senior Debt Securities
of any series may be waived by the Holders of a majority in principal amount of
all Outstanding Senior Debt Securities of that series, except in a case of
failure to pay principal or premium, if any, or interest or Additional Amounts
payable on any Senior Debt Security of that series for which payment had not
been subsequently made or in respect of a covenant or provision which cannot be
modified or amended without the consent of the Holder of each Outstanding Senior
Debt Security of such series affected.

  The Holders of a majority in principal amount of the Outstanding Senior Debt
Securities of a series may 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 Senior Debt Securities of such
series, provided that such direction shall not be in conflict with any rule of
law or the Senior Indenture.  Before proceeding to exercise any right or power
under the Senior Indenture at the direction of such Holders, the Trustee shall
be entitled to receive from such Holders reasonable security or indemnity
against the costs, expenses and liabilities which might be incurred by it in
complying with any such direction.

  The Company is required to furnish to the Trustee annually a statement as to
the fulfillment by the Company of all of its obligations under the Senior
Indenture.

      S&P 500 MARKET INDEX TARGET-TERM SECURITIES/SM/ DUE SEPTEMBER 16, 2002
                                  ("MITTS(R)")

     On March 14, 1997, Merrill Lynch & Co., Inc. (the "Company") issued an
aggregate principal amount of $175,000,000 (17,500,000 Units) of S&P 500 Market
Index Target-Term Securities due September 16, 2002 (the "Securities" or
"MITTS").  Each $10 principal amount of Securities will be deemed a "Unit" for
purposes of trading and transfer at the Securities Depository described below.
Units will be transferable by the Securities Depository, as more fully described
below, in denominations of whole Units.

  The Securities are debt securities of the Company, which were being issued in
denominations of $10 and integral multiples thereof, will bear no periodic
payments of interest and will mature on September 16, 2002. At maturity, a
beneficial owner of a Security will be entitled to receive, with respect to each
Security, the principal amount thereof plus an interest payment, if any (the
"Supplemental Redemption Amount"), based on the percentage increase, if any, in
the S&P 500 Composite Stock Price Index (the "Index") over the Starting Index
Value. The Supplemental Redemption Amount will in no event be less than zero.
The Securities are not redeemable or callable by the Company prior to maturity.
At maturity, a beneficial owner of a Security will receive the principal amount
of such Security plus the Supplemental Redemption Amount, if any, however, there
will be no other payment of interest, periodic or otherwise.

  The Supplemental Redemption Amount payable with respect to a Security at
maturity will equal the product of (A) the principal amount of the applicable
Security, (B) the percentage increase from the Starting Index Value to the
Ending Index Value, and (C) the Participation Rate. The Starting Index Value
equals 813.65 which was the closing value of the Index on the date the
Securities were priced by the Company for initial sale to the public (the
"Pricing Date"). The Ending Index Value, as more particularly described herein,
will be the average (arithmetic mean) of the closing values of the Index on
certain days, or, if certain events occur, the closing value of the Index on a
single day prior to the maturity of the Securities. The Participation Rate
equals 101%.

WHICH WILL BE PAID AT MATURITY, THE CALCULATION AND THE COMPOSITION OF THE
INDEX, AND CERTAIN TAX CONSEQUENCES TO BENEFICIAL OWNERS OF THE SECURITIES, SEE
"DESCRIPTION OF SECURITIES" AND "THE INDEX", RESPECTIVELY, IN THIS PROSPECTUS.
FOR OTHER INFORMATION THAT SHOULD BE CONSIDERED BY PROSPECTIVE INVESTORS, SEE

  Ownership of the Securities will be maintained in book-entry form by or
through the Depository. Beneficial owners of the Securities will not have the
right to receive physical certificates evidencing their ownership except under
the limited circumstances described herein.

  The Securities have been listed on the New York Stock Exchange under the
symbol "MIM".

  For the purpose of calculating the ratio of earnings to fixed charges,
"earnings" consists of earnings from continuing operations before income taxes
and fixed charges.  "Fixed charges" consists of interest costs, amortization of
debt expense, preferred stock dividend requirements of majority-owned
subsidiaries, and that portion of rentals estimated to be representative of the
interest factor.

                                 RISK FACTORS

PAYMENT AT MATURITY

 
  Supplemental Redemption Amount May be Zero.  Investors should be aware that if
the Ending Index Value does not exceed the Starting Index Value, beneficial
owners of the Securities will receive only the principal amount thereof at
maturity, even if the value of the Index at some point between the issue date
and the maturity date of the Securities exceeded the Starting Index Value.

  Yield may be Below Market Interest Rates on the Pricing Date.  A beneficial
owner of the Securities may receive no Supplemental Redemption Amount at
maturity, or a Supplemental Redemption Amount that is below what the Company
would pay as interest as of the Pricing Date if the Company issued non-callable
senior debt securities with a similar maturity as that of the Securities. The
return of principal of the Securities at maturity and the payment of the
Supplemental Redemption Amount, if any, may not reflect the full opportunity
costs implied by inflation or other factors relating to the time value of money.

  Yield on Securities will not Reflect Dividends.  The Index does not reflect
the payment of dividends on the stocks underlying it and therefore the yield
based on the Index to the maturity of the Securities will not produce the same
yield as if such underlying stocks were purchased and held for a similar period.

  State Law Limit on Interest Paid.  Because the 1983 Indenture provides that
the Securities will be governed by and construed in accordance with the laws of
New York, certain usury laws of New York State may apply. Under present New York
law, the maximum rate of interest is 25% per annum on a simple interest basis.
This limit may not apply to Securities in which $2,500,000 or more has been
invested. While the Company believes that New York law would be given effect by
a state or Federal court sitting outside of New York, state laws frequently
regulate the amount of interest that may be charged to and paid by a borrower
(including, in some cases, corporate borrowers). It is suggested that
prospective investors consult their personal advisors with respect to the
applicability of such laws. The Company will covenant for the benefit of the
Holders of the Securities, to the extent permitted by law, not to claim
voluntarily the benefits of any laws concerning usurious rates of interest
against a Holder of the Securities.

TRADING

  The Securities have been listed on the New York Stock Exchange under the
symbol "MIM". There is little precedent to indicate how the Securities will
trade in the secondary market or whether such market will be liquid.

  It is expected that the trading value of the Securities in the secondary
market will be affected by the creditworthiness of the Company and by a number
of other factors. The trading value of the Securities is expected to depend
substantially on the extent of the appreciation, if any, of the Index over the
Starting Index Value. If, however, Securities are sold prior to the maturity
date at a time when the Index exceeds the Starting Index Value, the sale price
may be at a substantial discount from the amount expected to be payable to the
beneficial owner if such excess of the Index over the Starting Index Value were
to prevail until maturity of the Securities because of the possible fluctuation
of the Index between the time of such sale and the time that the Ending Index
Value is determined. Furthermore, the price at which a beneficial owner will be
able to sell Securities prior to maturity may be at a discount, which could be
substantial, from the principal amount thereof, if, at such time, the Index is
below, equal to, or not sufficiently above the Starting Index Value. A discount
could also result from rising interest rates.

  In addition to the value of the Index, the trading value of the Securities may
be affected by a number of interrelated factors, including the creditworthiness
of the Company and those factors listed below. The relationship among these
factors is complex, including how these factors affect the relative value of the
principal amount of the

                                       5
<PAGE>
 
Securities to be repaid at maturity and the value of the Supplemental Redemption
Amount, if any. Accordingly, investors should be aware that factors other than
the level of the Index are likely to affect the Securities' trading value. The
expected effect on the trading value of the Securities of each of the factors
listed below, assuming in each case that all other factors are held constant, is
as follows:

  Interest Rates.  Because the Securities repay at a minimum the principal
amount thereof at maturity, the trading value of the Securities will likely be
affected by changes in interest rates. In general, if U.S. interest rates
increase, the trading value of the Securities is expected to decrease. If U.S.
interest rates decrease, the trading value of the Securities is expected to
increase. Interest rates may also affect the U.S. economy, and, in turn, the
value of the Index. Rising interest rates may lower the value of the Index and,
thus, the Securities. Falling interest rates may increase the value of the Index
and, thus, may increase the value of the Securities.

  Volatility of the Index.  If the volatility of the Index increases, the
trading value of the Securities is expected to increase. If the volatility of
the Index decreases, the trading value of the Securities is expected to
decrease.

  Time Remaining to Maturity.  The Securities may trade at a value above that
which may be inferred from the level of interest rates and the Index. This
difference will reflect a "time premium" due to expectations concerning the
value of the Index during the period prior to maturity of the Securities. As the
time remaining to maturity of the Securities decreases, however, this time
premium is expected to decrease, thus decreasing the trading value of the
Securities. In addition, the price at which a beneficial owner may be able to
sell Securities prior to maturity may be at a discount, which may be
substantial, from the principal amount of the Securities if the value of the
Index is below, equal to, or not sufficiently above the Starting Index Value.

  Dividend Rates in the United States.  If dividend rates on the stocks
comprising the Index increase, the value of the Securities is expected to
decrease. Conversely, if dividend rates on the stocks comprising the Index
decrease, the value of the Securities is expected to increase. However, in
general, rising U.S. corporate dividend rates may increase the value of the
Index and, in turn, increase the value of the Securities. Conversely, falling
U.S. dividend rates may decrease the value of the Index and, in turn, decrease
the value of the Securities.

  The impact of the factors specified above, excluding the value of the Index,
may offset, partially or in whole, any increase in the trading value of the
Securities that is attributable to an increase in the value of the Index. For
example, an increase in U.S. interest rates may cause the Securities to trade at
a discount from their initial offering price, even if the Index has appreciated
significantly. In general, assuming all relevant factors are held constant, the
effect on the trading value of the Securities of a given change in interest
rates, Index volatility and/or dividend rates of stocks comprising the Index is
expected to be less if it occurs later in the term of the Securities than if it
occurs earlier in the term of the Securities. The effect on the trading value of
the Securities of a given appreciation of the Index in excess of the Starting
Index Value is expected to be greater if it occurs later in the term of the
Securities than if it occurs earlier in the term of the Securities, assuming all
other relevant factors are held constant.

THE INDEX

  The value of the Index and the Supplemental Redemption Amount, if any, may be
adversely affected by political, economic and other developments that affect the
stocks underlying the Index.

OTHER CONSIDERATIONS

  It is suggested that prospective investors who consider purchasing the
Securities should reach an investment decision only after carefully considering
the suitability of the Securities in light of their particular circumstances.

  Investors should also consider the tax consequences of investing in the
Securities and should consult their tax advisors.

                                       6
<PAGE>
 
  MLPF&S or its affiliates may from time to time engage in transactions
involving the stocks underlying the Index for their proprietary accounts and for
other accounts under their management, which may influence the value of such
stocks and therefore the value of the Securities. MLPF&S and its affiliates will
also be the counterparties to the hedge of the Company's obligations under the
Securities.  Accordingly, under certain circumstances, conflicts of interest may
arise between MLPF&S's responsibilities as Calculation Agent, as defined below,
with respect to the Securities and its obligations under its hedge and its
status as a subsidiary of the Company. Under certain circumstances, the duties
of MLPF&S as Calculation Agent in determining the existence of Market Disruption
Events could conflict with the interests of MLPF&S as an affiliate of the issuer
of the Securities, Merrill Lynch & Co., Inc., and with the interests of the
holders of the Securities.

                           DESCRIPTION OF SECURITIES

GENERAL

  The Securities are to be issued as a series of Senior Debt Securities under
the Senior Indenture, referred to as the "1983 Indenture", which is more fully
described in the accompanying Prospectus. The Securities will mature on
September 16, 2002.

  While at maturity a beneficial owner of a Security will receive the principal
amount of such Security plus the Supplemental Redemption Amount, if any, there
will be no other payment of interest, periodic or otherwise. (See "Payment at
Maturity" below.)

  The Securities are not subject to redemption by the Company or at the option
of any beneficial owner prior to maturity. Upon the occurrence of an Event of
Default with respect to the Securities, beneficial owners of the Securities may
accelerate the maturity of the Securities, as described under "Description of
Securities--Events of Default and Acceleration" in this Prospectus.

  The Securities are to be issued in denominations of whole Units.

PAYMENT AT MATURITY

  At maturity, a beneficial owner of a Security will be entitled to receive the
principal amount thereof plus a Supplemental Redemption Amount, if any, all as
provided below. If the Ending Index Value does not exceed the Starting Index
Value, a beneficial owner of a Security will be entitled to receive only the
principal amount thereof.

  At maturity, a beneficial owner of a Security will be entitled to receive,
with respect to each such Security, (i) the principal amount thereof ($10 for
each Unit) and (ii) the Supplemental Redemption Amount equal in amount to:

<TABLE> 
<S>                  <C>                                          <C> 
  Principal Amount   X  Ending Index Value--Starting Index Value  X Participation Rate
                        ----------------------------------------
                                 Starting Index Value
</TABLE> 

provided, however, that in no event will the Supplemental Redemption Amount be
less than zero. The Starting Index Value equals 813.65, which was the closing
value of the Index on the date the Securities were priced by the Company for
initial sale to the public (i.e., the Pricing Date). The Participation Rate
equals 101%. The Ending Index Value will be determined by Merrill Lynch, Pierce,
Fenner & Smith Incorporated (the "Calculation Agent") and will equal the average
(arithmetic mean) of the closing values of the Index determined on each of the
first five Calculation Days during the Calculation Period. If there are fewer
than five Calculation Days, then the Ending Index Value will equal the average
(arithmetic mean) of the closing values of the Index on such Calculation Days,
and if there is only one Calculation Day, then the Ending Index Value will equal
the closing value of the Index on such Calculation Day. If no Calculation Days
occur during the Calculation Period because of Market Disruption Events,

                                       7
<PAGE>
 
then the Ending Index Value will equal the closing value of the Index determined
on the last scheduled Index Business Day in the Calculation Period, regardless
of the occurrences of a Market Disruption Event on such day. The "Calculation
Period" means the period from and including the seventh scheduled Index Business
Day prior to the maturity date to and including the second scheduled Index
Business Day prior to the maturity date. "Calculation Day" means any Index
Business Day during the Calculation Period on which a Market Disruption Event
has not occurred. For purposes of determining the Ending Index Value, an "Index
Business Day" is a day on which the New York Stock Exchange and the American
Stock Exchange are open for trading and the Index or any Successor Index, as
defined below, is calculated and published. All determinations made by the
Calculation Agent shall be at the sole discretion of the Calculation Agent and,
absent a determination by the Calculation Agent of a manifest error, shall be
conclusive for all purposes and binding on the Company and beneficial owners of
the Securities.

  The following table illustrates, for a range of hypothetical Ending Index
Values, (i) the total amount payable at maturity for each $10 principal amount
of Securities, (ii) the total rate of return to beneficial owners of the
Securities, (iii) the pretax annualized rate of return to beneficial owners of
Securities and (iv) the pretax annualized rate of return of an investment in the
stocks underlying the Index (which includes an assumed aggregate dividend yield
of 1.80% per annum, as more fully described below).

Index Value; (iv) no transaction fees or expenses; (v) a term for the Securities
from March 14, 1997 to September 16, 2002; and (vi) a final Index value equal to
the Ending Index Value. The aggregate dividend yield of the stocks underlying
the Index as of March 10, 1997 was approximately 1.80%.

(3) This is the Starting Index Value.

  The above figures are for purposes of illustration only. The actual
Supplemental Redemption Amount received by investors and the total and pretax
annualized rate of return resulting therefrom will depend entirely on the actual
Ending Index Value determined by the Calculation Agent as provided herein.

ADJUSTMENTS TO THE INDEX; MARKET DISRUPTION EVENTS

  If at any time the method of calculating the Index, or the value thereof, is
changed in any material respect, or if the Index is in any other way modified so
that such Index does not, in the opinion of the Calculation Agent, fairly
represent the value of the Index had such changes or modifications not been
made, then, from and after such time, the Calculation Agent shall, at the close
of business in New York, New York, on each date that the closing value with
respect to the Ending Index Value is to be calculated, make such adjustments as,
in the good faith judgment of the Calculation Agent, may be necessary in order
to arrive at a calculation of a value of a stock index comparable to the Index
as if such changes or modifications had not been made, and calculate such
closing value with reference to the Index, as adjusted. Accordingly, if the
method of calculating the Index is modified so that the value of such Index is a
fraction or a multiple of what it would have been if it had not been modified
(e.g., due to a split in the Index), then the Calculation Agent shall adjust
such Index in order to arrive at a value of the Index as if it had not been
modified (e.g., as if such split had not occurred).

  "Market Disruption Event" means either of the following events, as determined
by the Calculation Agent:

  (i) the suspension or material limitation (limitations pursuant to New York
Stock Exchange Rule 80A (or any applicable rule or regulation enacted or
promulgated by the New York Stock Exchange or any other self regulatory
organization or the Securities and Exchange Commission of similar scope as
determined by the Calculation Agent) on trading during significant market
fluctuations shall be considered "material" for purposes of this definition), in
each case, for more than two hours of trading in 100 or more of the securities
included in the Index, or

  (ii) the suspension or material limitation, in each case, for more than two
hours of trading (whether by reason of movements in price otherwise exceeding
levels permitted by the relevant exchange or otherwise) in (A) futures contracts
related to the Index which are traded on the Chicago Mercantile Exchange or (B)
option contracts related to the Index which are traded on the Chicago Board
Options Exchange, Inc.

  For the purposes of this definition, a limitation on the hours in a trading
day and/or number of days of trading will not constitute a Market Disruption
Event if it results from an announced change in the regular business hours of
the relevant exchange.

DISCONTINUANCE OF THE INDEX

  If S&P discontinues publication of the Index and S&P or another entity
publishes a successor or substitute index that the Calculation Agent determines,
in its sole discretion, to be comparable to such Index (any such index being
referred to hereinafter as a "Successor Index"), then, upon the Calculation
Agent's notification of such determination to the Trustee and the Company, the
Calculation Agent will substitute the Successor Index as calculated by S&P or
such other entity for the Index and calculate the Ending Index Value as
described above under

                                       9
<PAGE>
 
"Payment at Maturity". Upon any selection by the Calculation Agent of a
Successor Index, the Company shall cause notice thereof to be given to Holders
of the Securities.

  If S&P discontinues publication of the Index and a Successor Index is not
selected by the Calculation Agent or is no longer published on any of the
Calculation Days, the value to be substituted for the Index for any such
Calculation Day used to calculate the Supplemental Redemption Amount at maturity
will be a value computed by the Calculation Agent for each Calculation Day in
accordance with the procedures last used to calculate the Index prior to any
such discontinuance. If a Successor Index is selected or the Calculation Agent
calculates a value as a substitute for the Index as described below, such
Successor Index or value shall be substituted for the Index for all purposes,
including for purposes of determining whether a Market Disruption Event exists.

  If S&P discontinues publication of the Index prior to the period during which
the Supplemental Redemption Amount is to be determined and the Calculation Agent
determines that no Successor Index is available at such time, then on each
Business Day until the earlier to occur of (i) the determination of the Ending
Index Value and (ii) a determination by the Calculation Agent that a Successor
Index is available, the Calculation Agent shall determine the value that would
be used in computing the Supplemental Redemption Amount as described in the
preceding paragraph as if such day were a Calculation Day. The Calculation Agent
will cause notice of each such value to be published not less often than once
each month in The Wall Street Journal (or another newspaper of general
circulation), and arrange for information with respect to such values to be made
available by telephone. Notwithstanding these alternative arrangements,
discontinuance of the publication of the Index may adversely affect trading in
the Securities.

EVENTS OF DEFAULT AND ACCELERATION

  In case an Event of Default with respect to any Securities shall have occurred
and be continuing, the amount payable to a beneficial owner of a Security upon
any acceleration permitted by the Securities, with respect to each $10 principal
amount thereof, will be equal to: (i) the initial issue price ($10), plus (ii)
an additional amount of contingent interest calculated as though the date of
early repayment were the maturity date of the Securities. See "Description of
Securities--Payment at Maturity" in this Prospectus. If a bankruptcy proceeding
is commenced in respect of the Company, the claim of the beneficial owner of a
Security may be limited, under Section 502(b)(2) of Title 11 of the United
States Code, to the principal amount of the Security plus an additional amount
of contingent interest calculated as though the date of the commencement of the
proceeding were the maturity date of the Securities.

  In case of default in payment at the maturity date of the Securities (whether
at their stated maturity or upon acceleration), from and after the maturity date
the Securities shall bear interest, payable upon demand of the beneficial owners
thereof, at the rate of 6.75% per annum (to the extent that payment of such
interest shall be legally enforceable) on the unpaid amount due and payable on
such date in accordance with the terms of the Securities to the date payment of
such amount has been made or duly provided for.

DEPOSITORY

  Upon issuance, all Securities will be represented by one or more fully
registered global securities (the "Global Securities"). Each such Global
Security will be deposited with, or on behalf of, The Depository Trust Company
("DTC"), as Depository, registered in the name of DTC or a nominee thereof.
Unless and until it is exchanged in whole or in part for Securities in
definitive form, no Global Security may be transferred except as a whole by the
Depository to a nominee of such Depository or by a nominee of such Depository to
such Depository or another nominee of such Depository or by such Depository or
any such nominee to a successor of such Depository or a nominee of such
successor.

  DTC has advised the Company as follows: DTC is a limited-purpose trust company
organized under the

                                       10
<PAGE>
 
Banking Law of the State of New York, a member of the Federal Reserve System, a
"clearing corporation" within the meaning of the New York Uniform Commercial
Code, and a "clearing agency" registered pursuant to the provisions of Section
17A of the Securities Exchange Act of 1934, as amended. DTC was created to hold
securities of its participants ("Participants") and to facilitate the clearance
and settlement of securities transactions among its Participants in such
securities through electronic book-entry changes in accounts of the
Participants, thereby eliminating the need for physical movement of securities
certificates. DTC's Participants include securities brokers and dealers, banks,
trust companies, clearing corporations, and certain other organizations.

  DTC is owned by a number of Participants and by the New York Stock Exchange,
Inc., the American Stock Exchange, Inc. and the National Association of
Securities Dealers, Inc. Access to the DTC book-entry system is also available
to others, such as banks, brokers, dealers and trust companies that clear
through or maintain a custodial relationship with a Participant, either directly
or indirectly ("Indirect Participants").

  Purchases of Securities must be made by or through Participants, which will
receive a credit on the records of DTC. The ownership interest of each actual
purchaser of each Security ("Beneficial Owner") is in turn to be recorded on the
Participants' or Indirect Participants' records. Beneficial Owners will not
receive written confirmation from DTC of their purchase, but Beneficial Owners
are expected to receive written confirmations providing details of the
transaction, as well as periodic statements of their holdings, from the
Participant or Indirect Participant through which the Beneficial Owner entered
into the transaction. Ownership of beneficial interests in such Global Security
will be shown on, and the transfer of such ownership interests will be effected
only through, records maintained by DTC (with respect to interests of
Participants) and on the records of Participants (with respect to interests of
persons held through Participants). The laws of some states may require that
certain purchasers of securities take physical delivery of such securities in
definitive form. Such limits and such laws may impair the ability to own,
transfer or pledge beneficial interests in Global Securities.

  So long as DTC, or its nominee, is the registered owner of a Global Security,
DTC or its nominee, as the case may be, will be considered the sole owner or
Holder of the Securities represented by such Global Security for all purposes
under the 1983 Indenture. Except as provided below, Beneficial Owners in a
Global Security will not be entitled to have the Securities represented by such
Global Securities registered in their names, will not receive or be entitled to
receive physical delivery of the Securities in definitive form and will not be
considered the owners or Holders thereof under the 1983 Indenture, including for
purposes of receiving any reports delivered by the Company or the Trustee
pursuant to the 1983 Indenture. Accordingly, each Person owning a beneficial
interest in a Global Security must rely on the procedures of DTC and, if such
Person is not a Participant, on the procedures of the Participant through which
such Person owns its interest, to exercise any rights of a Holder under the 1983
Indenture. The Company understands that under existing industry practices, in
the event that the Company requests any action of Holders or that an owner of a
beneficial interest in such a Global Security desires to give or take any action
which a Holder is entitled to give or take under the 1983 Indenture, DTC would
authorize the Participants holding the relevant beneficial interests to give or
take such action, and such Participants would authorize Beneficial Owners owning
through such Participants to give or take such action or would otherwise act
upon the instructions of Beneficial Owners. Conveyance of notices and other
communications by DTC to Participants, by Participants to Indirect Participants,
and by Participants and Indirect Participants to Beneficial Owners will be
governed by arrangements among them, subject to any statutory or regulatory
requirements as may be in effect from time to time.

  Payment of the principal of, and any Supplemental Redemption Amount with
respect to, Securities registered in the name of DTC or its nominee will be made
to DTC or its nominee, as the case may be, as the Holder of the Global
Securities representing such Securities. None of the Company, the Trustee or any
other agent of the Company or agent of the Trustee will have any responsibility
or liability for any aspect of the records relating to or payments made on
account of beneficial ownership interests or for supervising or reviewing any
records relating to such beneficial ownership interests. The Company expects
that DTC, upon receipt of any payment of principal or any Supplemental
Redemption Amount in respect of a Global Security, will credit the accounts of
the

                                       11
<PAGE>
 
Participants with payment in amounts proportionate to their respective holdings
in principal amount of beneficial interest in such Global Security as shown on
the records of DTC. The Company also expects that payments by Participants to
Beneficial Owners will be governed by standing customer instructions and
customary practices, as is now the case with securities held for the accounts of
customers in bearer form or registered in "street name", and will be the
responsibility of such Participants.

  If (x) any Depository is at any time unwilling or unable to continue as
Depository and a successor depository is not appointed by the Company within 60
days, (y) the Company executes and delivers to the Trustee a Company Order to
the effect that the Global Securities shall be exchangeable or (z) an Event of
Default has occurred and is continuing with respect to the Securities, the
Global Securities will be exchangeable for Securities in definitive form of like
tenor and of an equal aggregate principal amount, in denominations of $10 and
integral multiples thereof. Such definitive Securities shall be registered in
such name or names as the Depository shall instruct the Trustee. It is expected
that such instructions may be based upon directions received by the Depository
from Participants with respect to ownership of beneficial interests in such
Global Securities.

SAME-DAY SETTLEMENT AND PAYMENT

  Settlement for the Securities will be made by the Underwriter in immediately
available funds. All payments of principal and the Supplemental Redemption
Amount, if any, will be made by the Company in immediately available funds so
long as the Securities are maintained in book-entry form.

                                   THE INDEX

  All disclosure contained in this Prospectus regarding the Index, including,
without limitation, its make-up, method of calculation and changes in its
components, is derived from publicly available information prepared by S&P.
Neither the Company nor the Underwriter takes any responsibility for the
accuracy or completeness of such information.

GENERAL

  The Index is published by S&P and is intended to provide an indication of the
pattern of common stock price movement. The calculation of the value of the
Index (discussed below in further detail) is based on the relative value of the
aggregate Market Value (as defined below) of the common stocks of 500 companies
as of a particular time as compared to the aggregate average Market Value of the
common stocks of 500 similar companies during the base period of the years 1941
through 1943. As of December 31, 1996, the 500 companies included in the Index
represented approximately 88% of the aggregate Market Value of common stocks
traded on The New York Stock Exchange; however, these 500 companies are not the
500 largest companies listed on The New York Stock Exchange and not all of these
500 companies are listed on such exchange. As of December 31, 1996, the
aggregate market value of the 500 companies included in the Index represented
approximately 71% of the aggregate market value of United States domestic,
public companies. S&P chooses companies for inclusion in the Index with the aim
of achieving a distribution by broad industry groupings that approximates the
distribution of these groupings in the common stock population of The New York
Stock Exchange, which S&P uses as an assumed model for the composition of the
total market. Relevant criteria employed by S&P include the viability of the
particular company, the extent to which that company represents the industry
group to which it is assigned, the extent to which the market price of that
Company's common stock is generally responsive to changes in the affairs of the
respective industry and the Market Value and trading activity of the common
stock of that company. As of December 31, 1996, the 500 companies included in
the Index were divided into 105 individual groups. These individual groups
comprised the following four main groups of companies (with the number of
companies currently included in each group indicated in parentheses):
Industrials (381), Utilities (40), Transportation (12) and Financial (67). S&P
may from time to time, in its sole discretion, add companies to, or delete
companies from, the Index to achieve the objectives stated above.

                                       12
<PAGE>
 
COMPUTATION OF THE INDEX

 S&P currently computes the Index as of a particular time as follows:

  (1) the product of the market price per share and the number of then
outstanding shares of each component stock is determined as of such time (such
product referred to as the "Market Value" of such stock);

  (2) the Market Value of all component stocks as of such time (as determined
under clause (1) above) are aggregated;

  (3) the mean average of the Market Values as of each week in the base period
of the years 1941 through 1943 of the common stock of each company in a group of
500 substantially similar companies is determined;

  (4) the mean average Market Values of all such common stocks over such base
period (as determined under clause (3) above) are aggregated (such aggregate
amount being referred to as the "Base Value");

  (5) the aggregate Market Value of all component stocks as of such time (as
determined under clause (2) above) is divided by the Base Value; and

 (6) the resulting quotient (expressed in decimals) is multiplied by ten.

While S&P currently employs the above methodology to calculate the Index, no
assurance can be given that S&P will not modify or change such methodology in a
manner that may affect the Supplemental Redemption Amount, if any, payable to
beneficial owners of Securities upon maturity or otherwise.

  S&P adjusts the foregoing formula to negate the effect of changes in the
Market Value of a component stock that are determined by S&P to be arbitrary or
not due to true market fluctuations. Such changes may result from such causes as
the issuance of stock dividends, the granting to shareholders of rights to
purchase additional shares of such stock, the purchase thereof by employees
pursuant to employee benefit plans, certain consolidations and acquisitions, the
granting to shareholders of rights to purchase other securities of the company,
the substitution by S&P of particular component stocks in the Index, and other
reasons. In all such cases, S&P first recalculates the aggregate Market Value of
all component stocks (after taking account of the new market price per share of
the particular component stock or the new number of outstanding shares thereof
or both, as the case may be) and then determines the New Base Value in
accordance with the following formula:

              Old Base Value X New Market Value  = New Base Value
                               ----------------                  
                               Old Market Value


  The result is that the Base Value is adjusted in proportion to any change in
the aggregate Market Value of all component stocks resulting from the causes
referred to above to the extent necessary to negate the effects of such causes
upon the Index.

LICENSE AGREEMENT

  S&P and Merrill Lynch Capital Services, Inc. have entered into a non-exclusive
license agreement providing for the license to Merrill Lynch Capital Services,
Inc., in exchange for a fee, of the right to use indices owned and published by
S&P in connection with certain securities, including the Securities, and the
Company is an authorized sublicensee thereof.

  The license agreement between S&P and Merrill Lynch Capital Services, Inc.
provides that the following language must be stated in this Prospectus:

                                       13
<PAGE>
 
         "The Securities are not sponsored, endorsed, sold or promoted by S&P.
     S&P makes no representation or warranty, express or implied, to the Holders
     of the Securities or any member of the public regarding the advisability of
     investing in securities generally or in the Securities particularly or the
     ability of the Index to track general stock market performance. S&P's only
     relationship to Merrill Lynch Capital Services, Inc. and the Company (other
     than transactions entered into in the ordinary course of business) is the
     licensing of certain servicemarks and trade names of S&P and of the Index
     which is determined, composed and calculated by S&P without regard to the
     Company or the Securities. S&P has no obligation to take the needs of the
     Company or the Holders of the Securities into consideration in determining,
     composing or calculating the Index. S&P is not responsible for and has not
     participated in the determination of the timing of the sale of the
     Securities, prices at which the Securities are to initially be sold, or
     quantities of the Securities to be issued or in the determination or
     calculation of the equation by which the Securities are to be converted
     into cash. S&P has no obligation or liability in connection with the
     administration, marketing or trading of the Securities."

                                  OTHER TERMS
GENERAL

     The Securities were issued as a series of Senior Debt Securities under the
Indenture (the "Senior Indenture"), dated as of April 1, 1983, as amended and
restated, between the Company and The Chase Manhattan Bank, formerly known as
Chemical Bank (successor by merger to Manufacturers Hanover Trust Company), as
trustee (the "Trustee"). A copy of the Senior Indenture is filed as an exhibit
to the registration statements relating to the Securities. The following
summaries of certain provisions of the Senior Indenture do not purport to be
complete and are subject to, and qualified in their entirety by reference to,
all provisions of the Senior Indenture, including the definition therein of
certain terms.

     The Senior Indenture provides that series of Senior Debt Securities may
from time to time be issued thereunder, without limitation as to aggregate
principal amount, in one or more series and upon such terms as the Company may
establish pursuant to the provisions thereof.

     The Senior Indenture provides that the Senior Indenture and the Securities
are governed by and construed in accordance with the laws of the State of New
York.

     The Senior Indenture provides that the Company may issue Senior Debt
Securities with terms different from those of Senior Debt Securities previously
issued, and "reopen" a previously issued series of Senior Debt Securities and
issue additional Senior Debt Securities of such series.

     The Senior Debt Securities are unsecured and rank pari passu with all other
unsecured and unsubordinated indebtedness of the Company.  However, since the
Company is a holding company, the right of the Company, and hence the right of
creditors of the Company (including the Holders of Senior Debt Securities), to
participate in any distribution of the assets of any subsidiary upon its
liquidation or reorganization or otherwise is necessarily subject to the prior
claims of creditors of the subsidiary, except to the extent that claims of the
Company itself as a creditor of the subsidiary may be recognized.  In addition,
dividends, loans and advances from certain subsidiaries, including MLPF&S, to
the Company are restricted by net capital requirements under the Exchange Act
and under rules of certain exchanges and other regulatory bodies.

LIMITATIONS UPON LIENS

     The Company may not, and may not permit any Subsidiary to, create, assume,
incur or permit to exist any indebtedness for borrowed money secured by a
pledge, lien or other encumbrance (except for certain liens specifically
permitted by the Senior Indenture) on the Voting Stock owned directly or
indirectly by the Company of any Subsidiary (other than a Subsidiary which, at
the time of the incurrence of such secured indebtedness, has

                                       14
<PAGE>
 
a net worth of less than $3,000,000) without making effective provision whereby
the Outstanding Senior Debt Securities will be secured equally and ratably with
such secured indebtedness.


LIMITATION ON DISPOSITION OF VOTING STOCK OF, AND MERGER AND SALE OF ASSETS BY,
MLPF&S

     The Indenture provides that the Company may not sell, transfer or otherwise
dispose of any Voting Stock of MLPF&S or permit MLPF&S to issue, sell or
otherwise dispose of any of its Voting Stock, unless, after giving effect to any
such transaction, MLPF&S remains a Controlled Subsidiary (defined in the Senior
Indenture to mean a corporation more than 80% of the outstanding shares of
Voting Stock of which are owned directly or indirectly by the Company).  In
addition, the Company may not permit MLPF&S to (i) merge or consolidate, unless
the surviving company is a Controlled Subsidiary or (ii) convey or transfer its
properties and assets substantially as an entirety, except to one or more
Controlled Subsidiaries.


MERGER AND CONSOLIDATION

     The Indenture provides that the Company may consolidate or merge with or
into any other corporation, and the Company may sell, lease or convey all or
substantially all of its assets to any corporation, provided that (i) the
corporation (if other than the Company) formed by or resulting from any such
consolidation or merger or which shall have received such assets shall be a
corporation organized and existing under the laws of the United States of
America or a state thereof and shall assume payment of the principal of (and
premium, if any) and interest on the Senior Debt Securities and the performance
and observance of all of the covenants and conditions of the Senior Indenture to
be performed or observed by the Company, and (ii) the Company or such successor
corporation, as the case may be, shall not immediately thereafter be in default
under the Senior Indenture.


MODIFICATION AND WAIVER

     Modification and amendment of the Indenture may be effected by the Company
and the Trustee with the consent of the Holders of 66 2/3% in principal amount
of the Outstanding Senior Debt Securities of each series issued pursuant to such
indenture and affected thereby, provided that no such modification or amendment
may, without the consent of the Holder of each Outstanding Senior Debt Security
affected thereby, (a) change the Stated Maturity of the principal of, or any
installment of interest or Additional Amounts payable on, any Senior Debt
Security or any premium payable on the redemption thereof, or change the
Redemption Price; (b) reduce the principal amount of, or the interest or
Additional Amounts payable on, any Senior Debt Security or reduce the amount of
principal which could be declared due and payable prior to the Stated Maturity;
(c) change place or currency of any payment of principal or any premium,
interest or Additional Amounts payable on any Senior Debt Security; (d) impair
the right to institute suit for the enforcement of any payment on or with
respect to any Senior Debt Security; (e) reduce the percentage in principal
amount of the Outstanding Senior Debt Securities of any series, the consent of
whose Holders is required to modify or amend the Indenture; or (f) modify the
foregoing requirements or reduce the percentage of Outstanding Senior Debt
Securities necessary to waive any past default to less than a majority.  No
modification or amendment of the Subordinated Indenture or any Subsequent
Indenture for Subordinated Debt Securities may adversely affect the rights of
any holder of Senior Indebtedness without the consent of such Holder.  Except
with respect to certain fundamental provisions, the Holders of at least a
majority in principal amount of Outstanding Senior Debt Securities of any series
may, with respect to such series, waive past defaults under the Indenture and
waive compliance by the Company with certain provisions thereof.

                                       15
<PAGE>
 
EVENTS OF DEFAULT

     Under the Senior Indenture, the following will be Events of Default with
respect to Senior Debt Securities of any series: (a) default in the payment of
any interest or Additional Amounts payable on any Senior Debt Security of that
series when due, continued for 30 days; (b) default in the payment of any
principal or premium, if any, on any Senior Debt Security of that series when
due; (c) default in the deposit of any sinking fund payment, when due, in
respect of any Senior Debt Security of that series; (d) default in the
performance of any other covenant of the Company contained in the Indenture for
the benefit of such series or in the Senior Debt Securities of such series,
continued for 60 days after written notice as provided in the Senior Indenture;
(e) certain events in bankruptcy, insolvency or reorganization; and (f) any
other Event of Default provided with respect to Senior Debt Securities of that
series.  The Trustee or the Holders of 25% in principal amount of the
Outstanding Senior Debt Securities of that series may declare the principal
amount (or such lesser amount as may be provided for in the Senior Debt
Securities of that series) of all Outstanding Senior Debt Securities of that
series and the interest due thereon and Additional Amounts payable in respect
thereof, if any to be due and payable immediately if an Event of Default with
respect to Senior Debt Securities of such series shall occur and be continuing
at the time of such declaration.  At any time after a declaration of
acceleration has been made with respect to Senior Debt Securities of any series
but before a judgment or decree for payment of money due has been obtained by
the Trustee, the Holders of a majority in principal amount of the Outstanding
Senior Debt Securities of that series may rescind any declaration of
acceleration and its consequences, if all payments due (other than those due as
a result of acceleration) have been made and all Events of Default have been
remedied or waived.  Any Event of Default with respect to Senior Debt Securities
of any series may be waived by the Holders of a majority in principal amount of
all Outstanding Senior Debt Securities of that series, except in a case of
failure to pay principal or premium, if any, or interest or Additional Amounts
payable on any Senior Debt Security of that series for which payment had not
been subsequently made or in respect of a covenant or provision which cannot be
modified or amended without the consent of the Holder of each Outstanding Senior
Debt Security of such series affected.

     The Holders of a majority in principal amount of the Outstanding Senior
Debt Securities of a series may 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 Senior Debt Securities of such
series, provided that such direction shall not be in conflict with any rule of
law or the Senior Indenture.  Before proceeding to exercise any right or power
under the Senior Indenture at the direction of such Holders, the Trustee shall
be entitled to receive from such Holders reasonable security or indemnity
against the costs, expenses and liabilities which might be incurred by it in
complying with any such direction.

     The Company is required to furnish to the Trustee annually a statement as
to the fulfillment by the Company of all of its obligations under the Senior
Indenture.

                           MERRILL LYNCH & CO., INC.
   TOP TEN YIELD MARKET INDEX TARGET-TERM SECURITIES(SM) DUE AUGUST 15, 2006
                                 ("MITTS(R)")

  On August 12, 1996, Merrill Lynch & Co., Inc. (the "Company") issued
$35,000,000 aggregate principal amount (3,500,000 Units) of Top Ten Yield Market
Index Target-Term Securities due August 15, 2006 (the "Securities" or the
"MITTS").  Each $10 principal amount of the Securities will be deemed a "Unit"
for purposes of trading and transfer at the Depository described below.  Units
will be transferable by the Depository, as more fully described below, in
denominations of whole Units.

  The Securities are debt securities of the Company, which were issued in
denominations of $10 and integral multiples thereof, will bear no periodic
payments of interest and will mature on August 15, 2006. At maturity, a
beneficial owner of a Security will be entitled to receive, with respect to each
Security, the principal amount thereof plus an interest payment (the
"Supplemental Redemption Amount") based on the percentage increase, if any, in
the Top Ten Yield Index (the "Index") over the Starting Index Value. The
Supplemental Redemption Amount will in no event be less than $2.40 per $10
principal amount of the Securities (the "Minimum Supplemental Redemption
Amount"), representing a minimum yield-to-maturity of 2.16% per annum calculated
on a semi-annual bond equivalent basis. The Index will reflect the price
movements and cash dividends on a portfolio of ten common stocks with the
highest dividend yields in the Dow Jones Industrial Average* (the "DJIA") on
July 26, 1996 that will be reconstituted annually to reflect the stocks having
the highest dividend yields in the DJIA (the "Top Ten Yield Stocks"), as more
particularly described herein. Subject to certain exceptions, the Index will be
reduced each calendar quarter by a value equal to 0.4375% of the then current
Index value. The Securities are not redeemable or callable by the Company prior
to maturity. While at maturity a beneficial owner of a Security will receive the
principal amount of such Security plus the Supplemental Redemption Amount there
will be no other payment of interest, periodic or otherwise.

  The Supplemental Redemption Amount payable with respect to a Security at
maturity will equal the product of (A) the principal amount of the applicable
Security, and (B) the percentage increase from the Starting Index Value to the
Ending Index Value, however, in no event will the Supplemental Redemption Amount
be less than the Minimum Supplemental Redemption Amount. The Starting Index
Value, as more particularly described herein, was set to 100 on the date the
Securities were priced by the Company for initial sale to the public ("the
Pricing Date"). The Ending Index Value, as more particularly described herein,
will be the average (arithmetic mean) of the closing values of the Index on
certain days, or, if certain events occur, the closing value of the Index on a
single day prior to the maturity of the Securities.

  FOR INFORMATION AS TO THE CALCULATION OF THE SUPPLEMENTAL REDEMPTION AMOUNT
WHICH WILL BE PAID AT MATURITY, THE CALCULATION AND THE COMPOSITION OF THE
INDEX, SEE "DESCRIPTION OF SECURITIES" AND "THE INDEX", RESPECTIVELY, IN THIS
PROSPECTUS. FOR OTHER INFORMATION THAT SHOULD BE CONSIDERED BY PROSPECTIVE
INVESTORS, SEE "RISK FACTORS" BEGINNING ON PAGE 3 OF THIS PROSPECTUS.

  Ownership of the Securities will be maintained in book-entry form by or
through the Depository. Beneficial owners of the Securities will not have the
right to receive physical certificates evidencing their ownership except under
the limited circumstances described herein.

  The Securities have been listed on the American Stock Exchange (the "AMEX")
under the symbol "MTT".

  For the purpose of calculating the ratio of earnings to fixed charges,

and fixed charges.  "Fixed charges" consists of interest costs, amortization of
debt expense, preferred stock dividend requirements of majority-owned
subsidiaries, and that portion of rentals estimated to be representative of the
interest factor.


                                  RISK FACTORS
PAYMENT AT MATURITY

  Supplemental Redemption Amount May Equal Minimum Supplemental Redemption
Amount.   Investors should be aware that if the Ending Index Value does not
exceed the Starting Index Value by more than 24%, beneficial owners of the
Securities will receive at maturity only the principal amount thereof and the
Minimum Supplemental Redemption Amount, even if the value of the Index at some
point between the issue date and the maturity date of the Securities exceeded
such amounts.

                                       3
<PAGE>
 
  Yield may be Below Market Interest Rates on the Pricing Date.   The Minimum
Supplemental Redemption Amount is below what the Company would pay as interest
as of the Pricing Date if the Company issued non-callable senior debt securities
with a similar maturity as that of the Securities. The return of principal of
the Securities at maturity and the payment of the Minimum Supplemental
Redemption Amount may not reflect the full opportunity costs implied by
inflation or other factors relating to the time value of money.

  Yield on Securities will not Reflect Yield on Securities Underlying the Index.
While the Index does reflect the payment of dividends on the stocks underlying
the Index as described in more detail below, the yield based on the Index to the
maturity of the Securities will not produce the same yield as if such underlying
stocks were purchased and held for a similar period. At the end of each calendar
quarter, the dividends accrued on the stocks underlying the Index will be
incorporated into the Index by adjusting the Share Multipliers of such stocks
and such amounts will thereafter be subject to the price movements of such
stocks. In addition, as described in more detail below, at the end of each
calendar quarter, an amount equal to 0.4375% of the current value of the Index
will be deducted from the value of the Index, provided that (i) there will be no
deduction at the end of the calendar quarter ending in September 1996 and the
deduction at the end of the calendar quarter ending in December 1996 will be
increased to reflect the quarterly rate of 0.4375% prorated for the period from
the date of the issuance of the Securities through the end of the calendar
quarter in December 1996, and (ii) there will be a prorated amount deducted on
July 31, 2006 equal to 0.1507% of the then current Index value to reflect the
quarterly rate of 0.4375% for the period from July 1, 2006 through July 31,
2006. Although the Index is based on stocks which are selected based on
dividends paid, the Securities will not pay any interest, periodic or otherwise,
prior to their maturity.

  State Law Limit on Interest Paid.   Because the Senior Indenture (as defined
below) provides that the Securities are governed by and construed in accordance
with the laws of New York, certain usury laws of New York State may apply. Under
present New York law, the maximum rate of interest is 25% per annum on a simple
interest basis. This limit may not apply to Securities in which $2,500,000 or
more has been invested. While the Company believes that New York law would be
given effect by a state or Federal court sitting outside of New York, state laws
frequently regulate the amount of interest that may be charged to and paid by a
borrower (including, in some cases, corporate borrowers). It is suggested that
prospective investors consult their personal advisors with respect to the
applicability of such laws. The Company will covenant for the benefit of the
Holders of the Securities, to the extent permitted by law, not to claim
voluntarily the benefits of any laws concerning usurious rates of interest
against a Holder of the Securities.


TRADING

  The Securities have been listed on the AMEX under the symbol "MTT".  It is
expected that the secondary market for the Securities will be affected by the
creditworthiness of the Company and by a number of other factors.

  The trading value of the Securities is expected to depend substantially on the
extent of the appreciation, if any, of the Index over the Starting Index Value.
If, however, Securities are sold prior to the maturity date at a time when the
Index exceeds the Starting Index Value, the sale price may be at a substantial
discount from the amount expected to be payable to the beneficial owner if such
excess of the Index over the Starting Index Value were to prevail until maturity
of the Securities because of the possible fluctuation of the Index between the
time of such sale and the time that the Ending Index Value is determined.
Furthermore, the price at which a beneficial owner will be able to sell
Securities prior to maturity may be at a discount, which could be substantial,
from the principal amount thereof, if, at such time, the Index is below, equal
to, or not sufficiently above the Starting Index Value. A discount could also
result from rising interest rates.

  In addition to the value of the Index, the trading value of the Securities may
be affected by a number of interrelated factors, including the creditworthiness
of the Company and those factors listed below. The relationship among these
factors is complex, including how these factors affect the relative value of the
principal amount of the

                                       4
<PAGE>
 
Securities to be repaid at maturity and the value of the Supplemental Redemption
Amount. Accordingly, investors should be aware that factors other than the level
of the Index are likely to affect the Securities' trading value. The expected
effect on the trading value of the Securities of each of the factors listed
below, assuming in each case that all other factors are held constant, is as
follows:

  Interest Rates.   Because the Securities repay at a minimum the principal
amount thereof at maturity, the trading value of the Securities will likely be
affected by changes in interest rates. In general, if U.S. interest rates
increase, the trading value of the Securities is expected to decrease. If U.S.
interest rates decrease, the trading value of the Securities is expected to
increase. Interest rates may also affect the U.S. economy, and, in turn, the
value of the Index. Rising interest rates may lower the value of the Index and,
thus, may decrease the trading value of the Securities. Falling interest rates
may increase the value of the Index and, thus, may increase the trading value of
the Securities.

  Volatility of the Index.   If the volatility of the Index increases, the
trading value of the Securities is expected to increase. If the volatility of
the Index decreases, the trading value of the Securities is expected to
decrease.

  Time Remaining to Maturity.   The Securities may trade at a value above that
which may be inferred from the level of interest rates and the Index. This
difference will reflect a "time premium" due to expectations concerning the
value of the Index during the period prior to maturity of the Securities. As the
time remaining to maturity of the Securities decreases, however, this time
premium is expected to decrease, thus decreasing the trading value of the
Securities. In addition, the price at which a beneficial owner may be able to
sell Securities prior to maturity may be at a discount, which may be
substantial, from the principal amount of the Securities if the value of the
Index is below, equal to, or not sufficiently above the Starting Index Value.

  The impact of the factors specified above, excluding the value of the Index,
may offset, partially or in whole, any increase in the trading value of the
Securities that is attributable to an increase in the value of the Index. For
example, an increase in U.S. interest rates may cause the Securities to trade at
a discount from their initial offering price, even if the Index has appreciated
significantly. In general, assuming all relevant factors are held constant, the
effect on the trading value of the Securities of a given change in interest
rates and/or Index volatility is expected to be less if it occurs later in the
term of the Securities than if it occurs earlier in the term of the Securities.
The effect on the trading value of the Securities of a given appreciation of the
Index in excess of the Starting Index Value is expected to be greater if it
occurs later in the term of the Securities than if it occurs earlier in the term
of the Securities, assuming all other relevant factors are held constant.

THE INDEX

  The value of the Index and the Supplemental Redemption Amount, if any, may be
adversely affected by political, economic and other developments that affect the
Top Ten Yield Stocks. The stocks underlying the Index will be adjusted annually
as more fully described below, see "The Index" in this Prospectus.

OTHER CONSIDERATIONS

  It is suggested that prospective investors who consider purchasing the
Securities should reach an investment decision only after carefully considering
the suitability of the Securities in light of their particular circumstances.

  Investors should also consider the tax consequences of investing in the
Securities and should consult their tax advisors.

  MLPF&S or its affiliates may from time to time engage in transactions
involving the Top Ten Yield Stocks underlying the Index for their proprietary
accounts and for other accounts under their management, which may influence the
value of such stocks and therefore the value of the Securities. MLPF&S and its
affiliates will also be the counterparties to the hedge of the Company's
obligations under the Securities.  Accordingly, under certain circumstances,
conflicts of interest may arise between MLPF&S's responsibilities as Calculation
Agent with respect to the Securities and its obligations under its hedge and its
status as a subsidiary of the Company. Under certain circumstances, the duties
of MLPF&S as Calculation Agent in determining the existence of Market Disruption

                                       5
<PAGE>
 
Events could conflict with the interests of MLPF&S as an affiliate of the issuer
of the Securities, Merrill Lynch & Co., Inc., and with the interests of the
holders of the Securities.


                           DESCRIPTION OF SECURITIES

GENERAL

  The Securities were issued as a series of Senior Debt Securities under the
Senior Indenture, referred to as the "Senior Indenture", which is more fully
described below.  The Securities will mature on August 15, 2006.

  At maturity, a beneficial owner of a Security will receive the principal
amount of such Security plus the Supplemental Redemption Amount, if any,
however, there will be no other payment of interest, periodic or otherwise. (See
"Payment at Maturity" below.)

  The Securities are not subject to redemption by the Company or at the option
of any beneficial owner prior to maturity. Upon the occurrence of an Event of
Default with respect to the Securities, beneficial owners of the Securities may
accelerate the maturity of the Securities, as described under "Description of
Securities--Events of Default and Acceleration" in this Prospectus and "Other
Terms--Events of Default" in this Prospectus.

  The Securities were issued in denominations of whole Units.


PAYMENT AT MATURITY

  At maturity, a beneficial owner of a Security will be entitled to receive the
principal amount thereof plus a Supplemental Redemption Amount all as provided
below. If the Ending Index Value does not exceed the Starting Index Value by
more than 24%, a beneficial owner of a Security will be entitled to receive only
the principal amount thereof and the Minimum Supplemental Redemption Amount.

  At maturity, a beneficial owner of a Security will be entitled to receive,
with respect to each such Security, (i) the principal amount thereof ($10 for
each Unit), and (ii) the Supplemental Redemption Amount equal in amount to:

     Principal Amount      X      Ending Index Value--Starting Index Value
                                  ----------------------------------------
                                          Starting Index Value

provided, however, that in no event will the Supplemental Redemption Amount be
less than $2.40 per $10 principal amount of the Securities. The Minimum
Supplemental Redemption Amount is equivalent to a rate of return of

                                       6
<PAGE>
 
2.16% per annum calculated on a semi-annual bond equivalent basis. The Starting
Index Value was set to 100 on the Pricing Date. The Ending Index Value will be
determined by MLPF&S (the "Calculation Agent") and will equal the average
(arithmetic mean) of the closing values of the Index determined on each of the
first five Calculation Days during the Calculation Period. If there are fewer
than five Calculation Days, then the Ending Index Value will equal the average
(arithmetic mean) of the closing values of the Index on such Calculation Days,
and if there is only one Calculation Day, then the Ending Index Value will equal
the closing value of the Index on such Calculation Day. If no Calculation Days
occur during the Calculation Period because of Market Disruption Events, then
the Ending Index Value will equal the closing value of the Index determined on
the last scheduled Index Business Day in the Calculation Period, regardless of
the occurrence of a Market Disruption Event on such day. The "Calculation
Period" means the period from and including the seventh scheduled Index Business
Day prior to the maturity date to and including the second scheduled Index
Business Day prior to the maturity date. "Calculation Day" means any Index
Business Day during the Calculation Period on which a Market Disruption Event
has not occurred. For purposes of determining the Ending Index Value, an "Index
Business Day" is a day on which the New York Stock Exchange and AMEX are open
for trading and trading generally occurs in the over-the-counter market for
equity securities and the Index is calculated and published by the AMEX. All
determinations made by the Calculation Agent shall be at the sole discretion of
the Calculation Agent and, absent a determination by the Calculation Agent of a
manifest error, shall be conclusive for all purposes and binding on the Company
and beneficial owners of the Securities.

  The following table illustrates, for a range of hypothetical Ending Index
Values, (i) the total amount payable at maturity for each $10 principal amount
of Securities, (ii) the pretax annualized rate of return to beneficial owners of
Securities, and (iii) the pretax annualized rate of return of an investment in
the stocks underlying the Index, as adjusted from time to time, that experience
the same price changes and dividend payments necessary to produce the indicated
hypothetical Ending Index Value (which reflects a deduction from the value of
the Index at the end of each calendar quarter equal to 0.4375% of the then
current Index value). The pretax annualized rate of return of the stocks
underlying the Index illustrated below is intended to reflect the return that
might be earned by an investor who seeks to replicate the Index return by
trading in the actual stocks underlying the Index and differs from the pretax
annualized rate of return on the Securities because of the percentage deducted
from the value of the Index each calendar quarter equal to 0.4375% of the then
current Index value. Investors seeking to replicate the Index return by trading
in the actual underlying stocks would not incur this periodic deduction although
they might incur commissions and other transaction-related costs.

(1) The annualized rates of return specified in the preceding table are
    calculated on a semiannual bond equivalent basis.
(2) This rate of return assumes, in addition to the price changes and dividend
    payments described above, (i) an initial investment of a fixed amount in the
    Top Ten Yield Stocks with the allocation of such amount reflecting an equal
    dollar-weighted portfolio of such stocks in the Index; (ii) a reconstruction
    of this portfolio investment on each ANNIVERSARY DATE so as to be an equal-
    dollar weighted portfolio of the ten common stocks in the DJIA having the
    highest Dividend Yield on the second scheduled Index Business Day prior to
    each such Anniversary

    Date; (iii) a compounded quarterly rate of return on the stocks which is
    greater than the compounded quarterly return on the Index by 0.4375% (the
    amount of the quarterly deduction applied to the Index), with dividends
    being reinvested on a quarterly basis; (iv) no transaction fees or expenses;
    (v) an investment term equal to the term of the Securities; and (vi) a final
    Index value equal to the Ending Index Value.

  The above figures are for purposes of illustration only. The actual
Supplemental Redemption Amount received by investors and the pretax annualized
rate of return resulting therefrom will depend entirely on the actual Ending
Index Value determined by the Calculation Agent as provided herein. Historical
data regarding the Index is included in this Prospectus under "The Index--
Historical Data on the Index".

ADJUSTMENTS TO THE INDEX; MARKET DISRUPTION EVENTS

  If at any time the method of calculating the Index, or the value thereof, is
changed in any material respect, or if the Index is in any other way modified so
that such Index does not, in the opinion of the Calculation Agent, fairly
represent the value of the Index had such changes or modifications not been
made, then, from and after such time, the Calculation Agent shall, at the close
of business in New York, New York, on each date that the closing value with
respect to the Ending Index Value is to be calculated, make such adjustments as,
in the good faith judgment of the Calculation Agent, may be necessary in order
to arrive at a calculation of a value of a stock index comparable to the Index
as if such changes or modifications had not been made, and calculate such
closing value with reference to the Index, as adjusted. Accordingly, if the
method of calculating the Index is modified so that the value of such Index is a
fraction or a multiple of what it would have been if it had not been modified
(e.g., due to a split in the Index), then the Calculation Agent shall adjust
such Index in order to arrive at a value of the Index as if it had not been
modified (e.g., as if such split had not occurred).

  "Market Disruption Event" means either of the following events, as determined
by the Calculation Agent:

  (i) the suspension or material limitation (limitations pursuant to New York
Stock Exchange Rule 80A (or any applicable rule or regulation enacted or
promulgated by the New York Stock Exchange or any other self regulatory
organization or the Commission of similar scope as determined by the Calculation
Agent) on trading during significant market fluctuations shall be considered
"material" for purposes of this definition), in the trading of one or more of
the Top Ten Yield Stocks on any exchange in the United States or in the over-
the-counter market for more than two hours of trading or during the period one-
half hour prior to the close of such trading, or

  (ii) the suspension or material limitation (whether by reason of movements in
price otherwise exceeding levels permitted by the relevant exchange or
otherwise) in option contracts related to one or more of the Top Ten Yield
Stocks traded on any exchange for more than two hours of trading or during the
period one-half hour prior to the close of such trading.

  For the purposes of this definition, a limitation on the hours in a trading
day and/or number of days of trading will not constitute a Market Disruption
Event if it results from an announced change in the regular business hours of
the relevant exchange.

                                       9

DISCONTINUANCE OF THE INDEX

  If the AMEX discontinues publication of the Index and the AMEX or another
entity publishes a successor or substitute index that the Calculation Agent
determines, in its sole discretion, to be comparable to such Index (any such
index being referred to hereinafter as a "Successor Index"), then, upon the
Calculation Agent's notification of such determination to the Trustee (as
defined below) and the Company, the Calculation Agent will substitute the
Successor Index as calculated by the AMEX or such other entity for the Index and
calculate the Ending Index Value as described above under "Payment at Maturity".
Upon any selection by the Calculation Agent of a Successor Index, the Company
shall cause notice thereof to be given to Holders of the Securities.

  If the AMEX discontinues publication of the Index and a Successor Index is not
selected by the Calculation Agent or is no longer published on any of the
Calculation Days, the value to be substituted for the Index for any such
Calculation Day used to calculate the Supplemental Redemption Amount at maturity
will be a value computed by the Calculation Agent for each Calculation Day in
accordance with the procedures last used to calculate the Index prior to any
such discontinuance. If a Successor Index is selected or the Calculation Agent
calculates a value as a substitute for the Index as described below, such
Successor Index or value shall be substituted for the Index for all purposes,
including for purposes of determining whether a Market Disruption Event exists.

  If the AMEX discontinues publication of the Index prior to the period during
which the Supplemental Redemption Amount is to be determined and the Calculation
Agent determines that no Successor Index is available at such time, then on each
Business Day until the earlier to occur of (i) the determination of the Ending
Index Value and (ii) a determination by the Calculation Agent that a Successor
Index is available, the Calculation Agent shall determine the value that would
be used in computing the Supplemental Redemption Amount as described in the
preceding paragraph as if such day were a Calculation Day. The Calculation Agent
will cause notice of each such value to be published not less often than once
each month in The Wall Street Journal (or another newspaper of general
circulation) (the "WSJ"), and arrange for information with respect to such
values to be made available by telephone. Notwithstanding these alternative
arrangements, discontinuance of the publication of the Index may adversely
affect trading in the Securities.

EVENTS OF DEFAULT AND ACCELERATION

  In case an Event of Default with respect to any Securities shall have occurred
and be continuing, the amount payable to a beneficial owner of a Security upon
any acceleration permitted by the Securities, with respect to each $10 principal
amount thereof, will be equal to: (i) the initial issue price ($10), plus (ii)
an additional amount of contingent interest calculated as though the date of
early repayment were the maturity date of the Securities. The Minimum
Supplemental Redemption Amount with respect to any such early redemption date
will be an amount equal to the interest which would have accrued on the
Securities from and including the date of original issuance to but excluding the
date of early redemption at an annualized rate of 2.16%, calculated on a semi-
annual bond equivalent basis. See "Description of Securities--Payment at
Maturity" in this Prospectus. If a bankruptcy proceeding is commenced in respect
of the Company, the claim of the beneficial owner of a Security may be limited,
under Section 502(b)(2) of Title 11 of the United States Code, to the principal
amount of the Security plus an additional amount of contingent interest
calculated as though the date of the commencement of the proceeding were the
maturity date of the Securities.

                                       10
<PAGE>
 
  In case of default in payment at the maturity date of the Securities (whether
at their stated maturity or upon acceleration), from and after the maturity date
the Securities shall bear interest, payable upon demand of the beneficial owners
thereof, at the rate of 7.76% per annum (to the extent that payment of such
interest shall be legally enforceable) on the unpaid amount due and payable on
such date in accordance with the terms of the Securities to the date payment of
such amount has been made or duly provided for.

DEPOSITORY

  Upon issuance, all Securities will be represented by one or more fully
registered global securities (the "Global Securities"). Each such Global
Security will be deposited with, or on behalf of, The Depository Trust Company
("DTC"), as Depository (the "Depositary"), registered in the name of DTC or a
nominee thereof. Unless and until it is exchanged in whole or in part for
Securities in definitive form, no Global Security may be transferred except as a
whole by the Depository to a nominee of such Depository or by a nominee of such
Depository to such Depository or another nominee of such Depository or by such
Depository or any such nominee to a successor of such Depository or a nominee of
such successor.

  DTC has advised the Company as follows: DTC is a limited-purpose trust company
organized under the Banking Law of the State of New York, a member of the
Federal Reserve System, a "clearing corporation" within the meaning of the New
York Uniform Commercial Code, and a "clearing agency" registered pursuant to the
provisions of Section 17A of the Exchange Act.  DTC was created to hold
securities of its participants ("Participants") and to facilitate the clearance
and settlement of securities transactions among its Participants in such
securities through electronic book-entry changes in accounts of the
Participants, thereby eliminating the need for physical movement of securities
certificates. DTC's Participants include securities brokers and dealers, banks,
trust companies, clearing corporations, and certain other organizations.

  DTC is owned by a number of Participants and by the New York Stock Exchange,
Inc., the American Stock Exchange, Inc. and the National Association of
Securities Dealers, Inc. Access to the DTC book-entry system is also available
to others, such as banks, brokers, dealers and trust companies that clear
through or maintain a custodial relationship with a Participant, either directly
or indirectly ("Indirect Participants").

  Purchases of Securities must be made by or through Participants, which will
receive a credit on the records of DTC. The ownership interest of each actual
purchaser of each Security ("Beneficial Owner") is in turn to be recorded on the
Participants' or Indirect Participants' records. Beneficial Owners will not
receive written confirmation from DTC of their purchase, but Beneficial Owners
are expected to receive written confirmations providing details of the
transaction, as well as periodic statements of their holdings, from the
Participant or Indirect Participant through which the Beneficial Owner entered
into the transaction. Ownership of beneficial interests in such Global Security
will be shown on, and the transfer of such ownership interests will be effected
only through, records maintained by DTC (with respect to interests of
Participants) and on the records of Participants (with respect to interests of
persons held through Participants). The laws of some states may require that
certain purchasers of securities take physical delivery of such securities in
definitive form. Such limits and such laws may impair the ability to own,
transfer or pledge beneficial interests in Global Securities.

  So long as DTC, or its nominee, is the registered owner of a Global Security,
DTC or its nominee, as the case may be, will be considered the sole owner or
Holder of the Securities represented by such Global Security for all purposes
under the Senior Indenture. Except as provided below, Beneficial Owners in a
Global Security will not be entitled to have the Securities represented by such
Global Securities registered in their names, will not receive or

                                       11
<PAGE>
 
be entitled to receive physical delivery of the Securities in definitive form
and will not be considered the owners or Holders thereof under the Senior
Indenture, including for purposes of receiving any reports delivered by the
Company or the Trustee pursuant to the Senior Indenture. Accordingly, each
Person owning a beneficial interest in a Global Security must rely on the
procedures of DTC and, if such Person is not a Participant, on the procedures of
the Participant through which such Person owns its interest, to exercise any
rights of a Holder under the Senior Indenture. The Company understands that
under existing industry practices, in the event that the Company requests any
action of Holders or that an owner of a beneficial interest in such a Global
Security desires to give or take any action which a Holder is entitled to give
or take under the Senior Indenture, DTC would authorize the Participants holding
the relevant beneficial interests to give or take such action, and such
Participants would authorize Beneficial Owners owning through such Participants
to give or take such action or would otherwise act upon the instructions of
Beneficial Owners. Conveyance of notices and other communications by DTC to
Participants, by Participants to Indirect Participants, and by Participants and
Indirect Participants to Beneficial Owners will be governed by arrangements
among them, subject to any statutory or regulatory requirements as may be in
effect from time to time.

  Payment of the principal of, and any Supplemental Redemption Amount with
respect to, Securities registered in the name of DTC or its nominee will be made
to DTC or its nominee, as the case may be, as the Holder of the Global
Securities representing such Securities. None of the Company, the Trustee or any
other agent of the Company or agent of the Trustee will have any responsibility
or liability for any aspect of the records relating to or payments made on
account of beneficial ownership interests or for supervising or reviewing any
records relating to such beneficial ownership interests. The Company expects
that DTC, upon receipt of any payment of principal or any Supplemental
Redemption Amount in respect of a Global Security, will credit the accounts of
the Participants with payment in amounts proportionate to their respective
holdings in principal amount of beneficial interest in such Global Security as
shown on the records of DTC. The Company also expects that payments by
Participants to Beneficial Owners will be governed by standing customer
instructions and customary practices, as is now the case with securities held
for the accounts of customers in bearer form or registered in "street name", and
will be the responsibility of such Participants.

  If (x) any Depository is at any time unwilling or unable to continue as
Depository and a successor depository is not appointed by the Company within 60
days, (y) the Company executes and delivers to the Trustee a Company Order to
the effect that the Global Securities shall be exchangeable or (z) an Event of
Default has occurred and is continuing with respect to the Securities, the
Global Securities will be exchangeable for Securities in definitive form of like
tenor and of an equal aggregate principal amount, in denominations of $10 and
integral multiples thereof. Such definitive Securities shall be registered in
such name or names as the Depository shall instruct the Trustee. It is expected
that such instructions may be based upon directions received by the Depository
from Participants with respect to ownership of beneficial interests in such
Global Securities.

SAME-DAY SETTLEMENT AND PAYMENT

  All payments of principal and the Supplemental Redemption Amount, if any, will
be made by the Company in immediately available funds so long as the Securities
are maintained in book-entry form.

                                   THE INDEX

TOP TEN YIELD INDEX

  The value of the Index on any Index Business Day will be calculated and
disseminated by the AMEX and will equal the Top Ten Yield Portfolio Value plus
the Current Quarter Dividends (as defined below) as of such Index Business Day.
The Top Ten Yield Portfolio Value will equal the sum of the products of the most
recently available market price and the applicable Share Multiplier for each Top
Ten Yield Stock. The AMEX will generally calculate and disseminate the value of
the Index based on the most recently reported prices of the stocks underlying
the Index (as reported by the exchange or trading system on which such
underlying stocks are listed or traded), at approximately 15-second intervals
during the AMEX's business hours and the end of each Index Business Day via the
Consolidated Tape Association's Network B.


 Initial Determination of Top Ten Yield Portfolio

  The initial stocks in the Top Ten Yield Portfolio and their respective
Dividend Yields and Share Multipliers are shown below, and have been determined
by the AMEX to be the ten common stocks in the DJIA having the highest Dividend
Yield on July 26, 1996 (the "Initial Stocks"). "Dividend Yield" for each common
stock is determined by the AMEX by annualizing the last quarterly or semi-annual
ordinary cash dividend for which the ex-dividend date has occurred, excluding
any extraordinary dividend as determined by the AMEX in its sole discretion, and
dividing the result by the last available sale price for each stock on its
primary exchange on the date such Dividend Yield is to be determined.

  The average (mean) dividend yield of the ten Initial Stocks contained in the
Index as of July 26, 1996 was 3.30%.

  The initial Share Multiplier for each Initial Stock was determined by the AMEX
and indicates the number of shares of each such Initial Stock, or portion
thereof, given the closing market price of such Initial Stock on the Pricing
Date, required to be included in the calculation of the original Top Ten Yield
Portfolio Value so that each Initial Stock represents approximately an equal
percentage of the starting value of the Index (i.e., 100) as of the Pricing
Date. The respective Share Multipliers will remain constant unless adjusted for
certain corporate events, quarterly dividend adjustments and annual
reconstitutions as described below. The initial Share Multipliers for each of
the Initial Stocks are set forth in the above table.


 Annual Top Ten Yield Portfolio Reconstitution

  As of the close of business on each Anniversary Date (as defined below)
through the applicable Anniversary Date in 2005, the content of the Top Ten
Yield Portfolio shall be reconstituted so as to include the ten common stocks in
the DJIA having the highest Dividend Yield (the "New Stocks") on the second
scheduled Index Business Day prior to such Anniversary Date (the "Annual
Determination Date"), provided, however that the AMEX will only add a stock
having characteristics as of such Annual Determination Date that will permit the
Index to remain within certain criteria specified in the AMEX rules and within
the applicable rules of the Securities and Exchange Commission. Such criteria
and rules will apply only on an Annual Determination Date to exclude a proposed
New Stock. If a proposed New Stock does not meet such criteria or rules, the
AMEX will replace it with the common stock in the DJIA with the next highest
Dividend Yield which does meet such criteria and rules. These criteria currently
provide, among other things, (1) that each component stock must have a minimum
market value of at least $75 million, except that up to 10% of the component
securities in the Index may have a market value of $50 million; (2) that each
component stock must have an average monthly trading volume in the preceding six
months of not less than 1,000,000 shares, except that up to 10% of the component
stocks in the Index may have an average monthly trading volume of 500,000 shares
or more in the last six months; (3) 90% of the Index's numerical Index value and
at least 80% of the total number of component stocks will meet the then current
criteria for standardized option trading set forth in the rules of the AMEX; and
(4) all component stocks will either be listed on the AMEX, the New York Stock
Exchange, or traded through the facilities of the National Association of
Securities Dealers Automated Quotation System and reported as National Market
System securities.

  The Share Multiplier for each New Stock will be determined by the AMEX and
will indicate the number of shares of each New Stock, given the closing market
price of such New Stock on the Anniversary Date, required to be included in the
calculation of the Top Ten Yield Portfolio Value so that each New Stock
represents approximately an equal percentage of a value equal to the Index in
effect at the close of business on such Anniversary Date. As an example, if the
Index in effect at the close of business on an Anniversary Date equaled 200,
then each of the ten New Stocks relating to such Anniversary Date would be
allocated a portion of the value of the Index equal to 20 and if the closing
market price of one such New Stock on the Anniversary Date was 40, the
applicable Share Multiplier would be 0.5. If the Index equaled 80, then each of
the ten New Stocks would be allocated a portion of the value of the Index equal
to 8 and if the closing market price of one such New Stock on the Anniversary
Date was 40, the applicable Share Multiplier would be 0.2. The last Anniversary
Date on which such reconstitution will occur will be the Anniversary Date in
2005, which will be approximately one year prior to the maturity date of the
Securities. "Anniversary Date" shall mean the anniversary date of the date the
Securities are initially issued; provided, however, that if such date is not an
Index Business Day or a Market Disruption Event occurs on such date, then the
Anniversary Date for such year shall mean the immediately succeeding Index
Business Day on which a Market Disruption Event does not occur. "Top Ten Yield
Stock" at any time shall mean the stocks contained in the Top Ten Yield
Portfolio at such time.

DOW JONES INDUSTRIAL AVERAGE

  The DJIA is comprised of 30 common stocks chosen by the editors of the WSJ as
representative of the broad market of American industry generally. The companies
are major factors in their industries and their stocks are typically widely held
by individuals and institutional investors. Changes in the composition of the
DJIA are made entirely by the editors of the WSJ without consultation with the
companies, the stock exchange or any official agency or the Company. For the
sake of continuity, changes are made infrequently. Most substitutions have been
the result of mergers, but from time to time, changes may be made to achieve a
better representation. The components of the DJIA may be changed at any time for
any reason. Dow Jones & Company, Inc., publisher of the WSJ, is not affiliated
with the Company, has not participated in any way in the creation of the
Securities or in the selection of stocks to be included in the Top Ten Yield
Portfolio and has not reviewed or approved any information included in this
Prospectus.

  The first DJIA, consisting of 12 stocks, was published in the WSJ in 1896. The
list grew to 20 stocks in 1916 and to 30 stocks on October 1, 1928. For two
periods of 17 consecutive years each, there were no changes to the list; March
15, 1939-July 2, 1956 and June 2, 1959-August 8, 1976.

  The Company or its affiliates may presently or from time to time engage in
business with one or more of the issuers of the Top Ten Yield Portfolio stocks,
including extending loans to, or making equity investments in, such issuers or
providing advisory services to such issuers, including merger and acquisition
advisory services. In the course of such business, the Company or its affiliates
may acquire non-public information with respect to such issuers and, in
addition, one or more affiliates of the Company may publish research reports
with respect to such issuers. The Company does not make any representation to
any purchaser of Securities with respect to any matters whatsoever relating to
such issuers. Any prospective purchaser of Securities should undertake an
independent investigation of the issuers of the Top Ten Yield Portfolio stocks
as in its judgment is appropriate to make an informed decision with respect to
an investment in the Securities. The composition of the Index does not reflect
any investment or sell recommendations of the Company or its affiliates.


CASH DIVIDENDS

 Current Quarter Dividend

  As described above, the value of the Index will include an amount reflecting
Current Quarter Dividends. "Current Quarter Dividends" for any day will be
determined by the AMEX and will equal the sum of the Dividend Payment for each
Top Ten Yield Stock. The "Dividend Payment" with respect to a Top Ten Yield
Stock for any day will equal the sum of the products of (i) each dividend paid
by the issuer of such Top Ten Yield Stock on one share of such Top Ten Yield
Stock during the Current Quarter (not including any reinvestment thereof)
multiplied by (ii) the Share Multiplier applicable to such Top Ten Yield Stock
at the time each such dividend is paid. A dividend will be considered paid by an
issuer at the open of business on the ex-dividend date (i.e., generally, the
trading day on which the market price of the stock reflects the payment of the
dividend). "Current Quarter" shall mean the period from and including August 9,
1996 through December 31, 1996, and after December 31, 1996, from and including
the first day of the then current calendar quarter containing the day on which
the applicable Dividend Payment is being determined to and including the day on
which the applicable Dividend Payment is being determined.

                                       15
<PAGE>
 
 Quarterly Stock Dividend

  As of the first day of the start of each calendar quarter, the AMEX will
allocate the Current Quarter Dividends as of the end of the immediately
preceding calendar quarter to each then outstanding Top Ten Yield Stock. The
amount of the Current Quarter Dividends allocated to each Top Ten Yield Stock
will equal the percentage of the value of such Top Ten Yield Stock contained in
the Top Ten Yield Portfolio relative to the value of the entire Top Ten Yield
Portfolio based on the closing market price on the last Index Business Day in
the immediately preceding calendar quarter. The Share Multiplier of each such
outstanding Top Ten Yield Stock will be increased to reflect the number of
shares, or portion of a share, that the amount of the Current Quarter Dividend
allocated to such Top Ten Yield Stock can purchase of each such Top Ten Yield
Stock based on the closing market price on the last Index Business Day in the
immediately preceding calendar quarter.


 Quarterly Deduction

  At the end of each calendar quarter, the Index will be reduced by a value
equal to 0.4375% of the then current Index, provided that (i) there will be no
deduction at the end of the calendar quarter ending in September 1996 and the
deduction at the end of the calendar quarter ending in December 1996 will be
increased to reflect the quarterly rate of 0.4375% prorated for the period from
the date of the issuance of the Securities through the end of the calendar
quarter in December 1996 and (ii) the Index will be reduced at the close of
business on July 31, 2006 by a value equal to 0.1507% of the closing value of
the Index on such date. With respect to the period ending December 31, 1996, the
quarterly rate of 0.4375% will be prorated by multiplying it by a factor equal
to the result of dividing the number of days in the period from the date the
Securities are issued through the calendar quarter ending in December 1996 by
90.


ADJUSTMENTS TO THE SHARE MULTIPLIER AND TOP TEN YIELD PORTFOLIO

  The Share Multiplier with respect to any Top Ten Yield Stock and the Top Ten
Yield Portfolio will be adjusted as follows:

  1.   If a Top Ten Yield Stock is subject to a stock split or reverse stock
split, then once such split has become effective, the Share Multiplier relating
to such Top Ten Yield Stock will be adjusted to equal the product of the number
of shares issued with respect to one such share of such Top Ten Yield Stock and
the prior multiplier.

  2.   If a Top Ten Yield Stock is subject to a stock dividend (issuance of
additional shares of the Top Ten Yield Stock) that is given equally to all
holders of shares of the issuer of such Top Ten Yield Stock, then once the
dividend has become effective and such Top Ten Yield Stock is trading ex-
dividend, the Share Multiplier will be adjusted so that the new Share Multiplier
shall equal the former Share Multiplier plus the product of the number of shares
of such Top Ten Yield Stock issued with respect to one such share of such Top
Ten Yield Stock and the prior multiplier.

                                       16
<PAGE>
 
  3.   If the issuer of a Top Ten Yield Stock is being liquidated or is subject
to a proceeding under any applicable bankruptcy, insolvency or other similar
law, such Top Ten Yield Stock will continue to be included in the Top Ten Yield
Portfolio so long as a Market Price for such Top Ten Yield Stock is available.
If a market price is no longer available for a Top Ten Yield Stock for whatever
reason, including the liquidation of the issuer of such Top Ten Yield Stock or
the subjection of the issuer of such Top Ten Yield Stock to a proceeding under
any applicable bankruptcy, insolvency or other similar law, then the value of
such Top Ten Yield Stock will equal zero in connection with calculating the Top
Ten Yield Portfolio Value for so long as no market price is available, and no
attempt will be made to immediately find a replacement stock or increase the
value of the Top Ten Yield Portfolio to compensate for the deletion of such Top
Ten Yield Stock. If a market price is no longer available for a Top Ten Yield
Stock as described above, the Top Ten Yield Portfolio Value will be computed
based on the remaining Top Ten Yield Stocks for which market prices are
available and no new stock will be added to the Top Ten Yield Portfolio until
the annual reconstitution of the Top Ten Yield Portfolio. As a result, there may
be periods during which the Top Ten Yield Portfolio contains fewer than ten Top
Ten Yield Stocks.

  4.   If the issuer of a Top Ten Yield Stock has been subject to a merger or
consolidation and is not the surviving entity or is nationalized, then a value
for such Top Ten Yield Stock will be determined at the time such issuer is
merged or consolidated or nationalized and will equal the last available market
price for such Top Ten Yield Stock and that value will be constant until the Top
Ten Yield Portfolio is reconstituted. At such time, no adjustment will be made
to the Share Multiplier of such Top Ten Yield Stock.

  5.   If the issuer of a Top Ten Yield Stock issues to all of its shareholders
equity securities that are publicly traded of an issuer other than the issuer of
the Top Ten Yield Stock, then such new equity securities will be added to the
Top Ten Yield Portfolio as a new Top Ten Yield Stock. The Share Multiplier for
such new Top Ten Yield Stock will equal the product of the original Share
Multiplier with respect to the Top Ten Yield Stock for which the new Top Ten
Yield Stock is being issued (the "Original Top Ten Yield Stock") and the number
of shares of the new Top Ten Yield Stock issued with respect to one share of the
Original Top Ten Yield Stock.

  No adjustments of any Share Multiplier of a Top Ten Yield Stock will be
required unless such adjustment would require a change of at least 1% in the
Share Multiplier then in effect. The Share Multiplier resulting from any of the
adjustments specified above will be rounded to the nearest ten-thousandth with
five hundred-thousandths being rounded upward.

  The AMEX expects that no adjustments to the Share Multiplier of any Top Ten
Yield Stock or to the Top Ten Yield Portfolio will be made other than those
specified above, however, the AMEX may at its discretion make adjustments to
maintain the value of the Index if certain events would otherwise alter the
value of the Index despite no change in the market prices of the Top Ten Yield
Stocks.

HISTORICAL PERFORMANCE OF THE INDEX

  A potential investor should review the historical performance of the Index.
The historical performance of the Index should not be taken as an indication of
future performance, and no assurance can be given that the Index will increase
sufficiently to cause the beneficial owners of the Securities to receive an
amount in excess of the principal amount at the maturity of the Securities.

  OTHER TERMS

GENERAL

   The Securities were issued as a series of Senior Debt Securities under the
Indenture (the "Senior Indenture"), dated as of April 1, 1983, as amended and
restated, between the Company and The Chase Manhattan Bank, formerly known as
Chemical Bank (successor by merger to Manufacturers Hanover Trust Company), as
trustee (the "Trustee"). A copy of the Senior Indenture is filed as an exhibit
to the registration statements relating to the Securities. The following
summaries of certain provisions of the Senior Indenture do not purport to be
complete and are subject to, and qualified in their entirety by reference to,
all provisions of the Senior Indenture, including the definition therein of
certain terms.

   The Senior Indenture provides that series of Senior Debt Securities may from
time to time be issued thereunder, without limitation as to aggregate principal
amount, in one or more series and upon such terms as the Company may establish
pursuant to the provisions thereof.

   The Senior Indenture provides that the Senior Indenture and the Securities
are governed by and construed in accordance with the laws of the State of New
York.

   The Senior Indenture provides that the Company may issue Senior Debt
Securities with terms different from those of Senior Debt Securities previously
issued, and "reopen" a previously issued series of Senior Debt Securities and
issue additional Senior Debt Securities of such series.

   The Senior Debt Securities are unsecured and rank pari passu with all other
unsecured and unsubordinated indebtedness of the Company.  However, since the
Company is a holding company, the right of the Company, and hence the right of
creditors of the Company (including the Holders of Senior Debt Securities), to
participate in any distribution of the assets of any subsidiary upon its
liquidation or reorganization or otherwise is necessarily subject to the prior
claims of creditors of the subsidiary, except to the extent that claims of the
Company itself as a creditor of the subsidiary may be recognized.  In addition,
dividends, loans and advances from certain subsidiaries, including MLPF&S, to
the Company are restricted by net capital requirements under the Exchange Act
and under rules of certain exchanges and other regulatory bodies.


LIMITATIONS UPON LIENS

   The Company may not, and may not permit any Subsidiary to, create, assume,
incur or permit to exist any indebtedness for borrowed money secured by a
pledge, lien or other encumbrance (except for certain liens specifically
permitted by the Senior Indenture) on the Voting Stock owned directly or
indirectly by the Company of any Subsidiary (other than a Subsidiary which, at
the time of the incurrence of such secured indebtedness, has a net worth of less
than $3,000,000) without making effective provision whereby the Outstanding
Senior Debt Securities will be secured equally and ratably with such secured
indebtedness.

<PAGE>
 
LIMITATION ON DISPOSITION OF VOTING STOCK OF, AND MERGER AND SALE OF ASSETS BY,
MLPF&S

   The Indenture provides that the Company may not sell, transfer or otherwise
dispose of any Voting Stock of MLPF&S or permit MLPF&S to issue, sell or
otherwise dispose of any of its Voting Stock, unless, after giving effect to any
such transaction, MLPF&S remains a Controlled Subsidiary (defined in the Senior
Indenture to mean a corporation more than 80% of the outstanding shares of
Voting Stock of which are owned directly or indirectly by the Company).  In
addition, the Company may not permit MLPF&S to (i) merge or consolidate, unless
the surviving company is a Controlled Subsidiary or (ii) convey or transfer its
properties and assets substantially as an entirety, except to one or more
Controlled Subsidiaries.


MERGER AND CONSOLIDATION

   The Indenture provides that the Company may consolidate or merge with or into
any other corporation, and the Company may sell, lease or convey all or
substantially all of its assets to any corporation, provided that (i) the
corporation (if other than the Company) formed by or resulting from any such
consolidation or merger or which shall have received such assets shall be a
corporation organized and existing under the laws of the United States of
America or a state thereof and shall assume payment of the principal of (and
premium, if any) and interest on the Senior Debt Securities and the performance
and observance of all of the covenants and conditions of the Senior Indenture to
be performed or observed by the Company, and (ii) the Company or such successor
corporation, as the case may be, shall not immediately thereafter be in default
under the Senior Indenture.


MODIFICATION AND WAIVER

   Modification and amendment of the Indenture may be effected by the Company
and the Trustee with the consent of the Holders of 66 2/3% in principal amount
of the Outstanding Senior Debt Securities of each series issued pursuant to such
indenture and affected thereby, provided that no such modification or amendment
may, without the consent of the Holder of each Outstanding Senior Debt Security
affected thereby, (a) change the Stated Maturity of the principal of, or any
installment of interest or Additional Amounts payable on, any Senior Debt
Security or any premium payable on the redemption thereof, or change the
Redemption Price; (b) reduce the principal amount of, or the interest or
Additional Amounts payable on, any Senior Debt Security or reduce the amount of
principal which could be declared due and payable prior to the Stated Maturity;
(c) change place or currency of any payment of principal or any premium,
interest or Additional Amounts payable on any Senior Debt Security; (d) impair
the right to institute suit for the enforcement of any payment on or with
respect to any Senior Debt Security; (e) reduce the percentage in principal
amount of the Outstanding Senior Debt Securities of any series, the consent of
whose Holders is required to modify or amend the Indenture; or (f) modify the
foregoing requirements or reduce the percentage of Outstanding Senior Debt
Securities necessary to waive any past default to less than a majority.  No
modification or amendment of the Subordinated Indenture or any Subsequent
Indenture for Subordinated Debt Securities may adversely affect the rights of
any holder of Senior Indebtedness without the consent of such Holder.  Except
with respect to certain fundamental provisions, the Holders of at least a
majority in principal amount of Outstanding Senior Debt Securities of any series
may, with respect to such series, waive past defaults under the Indenture and
waive compliance by the Company with certain provisions thereof.

EVENTS OF DEFAULT

   Under the Senior Indenture, the following will be Events of Default with
respect to Senior Debt Securities of any series: (a) default in the payment of
any interest or Additional Amounts payable on any Senior Debt Security of that
series when due, continued for 30 days; (b) default in the payment of any
principal or premium, if any, on any Senior Debt Security of that series when
due; (c) default in the deposit of any sinking fund payment, when due, in
respect of any Senior Debt Security of that series; (d) default in the
performance of any other covenant of the Company contained in the Indenture for
the benefit of such series or in the Senior Debt Securities of such series,
continued for 60 days after written notice as provided in the Senior Indenture;
(e) certain events in bankruptcy, insolvency or reorganization; and (f) any
other Event of Default provided with respect to Senior Debt Securities of that
series.  The Trustee or the Holders of 25% in principal amount of the
Outstanding Senior Debt Securities of that series may declare the principal
amount (or such lesser amount as may be provided for in the Senior Debt
Securities of that series) of all Outstanding Senior Debt Securities of that
series and the interest due thereon and Additional Amounts payable in respect
thereof, if any to be due and payable immediately if an Event of Default with
respect to Senior Debt Securities of such series shall occur and be continuing
at the time of such declaration.  At any time after a declaration of
acceleration has been made with respect to Senior Debt Securities of any series
but before a judgment or decree for payment of money due has been obtained by
the Trustee, the Holders of a majority in principal amount of the Outstanding
Senior Debt Securities of that series may rescind any declaration of
acceleration and its consequences, if all payments due (other than those due as
a result of acceleration) have been made and all Events of Default have been
remedied or waived.  Any Event of Default with respect to Senior Debt Securities
of any series may be waived by the Holders of a majority in principal amount of
all Outstanding Senior Debt Securities of that series, except in a case of
failure to pay principal or premium, if any, or interest or Additional Amounts
payable on any Senior Debt Security of that series for which payment had not
been subsequently made or in respect of a covenant or provision which cannot be
modified or amended without the consent of the Holder of each Outstanding Senior
Debt Security of such series affected.

   The Holders of a majority in principal amount of the Outstanding Senior Debt
Securities of a series may 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 Senior Debt Securities of such
series, provided that such direction shall not be in conflict with any rule of
law or the Senior Indenture.  Before proceeding to exercise any right or power
under the Senior Indenture at the direction of such Holders, the Trustee shall
be entitled to receive from such Holders reasonable security or indemnity
against the costs, expenses and liabilities which might be incurred by it in
complying with any such direction.

   The Company is required to furnish to the Trustee annually a statement as to
the fulfillment by the Company of all of its obligations under the Senior
Indenture.

        PAYABLE WITH SHARES OF COMMON STOCK OF COX COMMUNICATIONS, INC.
                         (OR CASH WITH AN EQUAL VALUE)
                              --------------------

   On May 29, 1996, Merrill Lynch & Co., Inc. (the "Company") issued 9,775,000
of its Structured Yield Product Exchangeable for Stock(SM) 6% STRYPES(SM) Due 
June 1, 1999 (each, a "STRYPES"). The issue price of each STRYPES was $22.875,
which amount was equal to the last sale price of the Class A Common Stock, par
value $1.00 per share (the "Cox Common Stock"), of Cox Communications, Inc., a
Delaware corporation ("Cox"), on May 22, 1996, as reported on the New York Stock
Exchange (the "Initial Price"). The STRYPES will mature on June 1, 1999 (the
"Maturity Date"). Interest on the STRYPES, at the rate of 6% of the issue price
per annum, is payable in cash quarterly in arrears on March 1, June 1, September
1 and December 1, beginning September 1, 1996. The STRYPES are unsecured
obligations of the Company ranking pari passu with all of its other unsecured
and unsubordinated indebtedness. See "Description of the STRYPES-Ranking." On
the Maturity Date, unless previously redeemed, the Company will pay and
discharge each STRYPES by delivering to the holder thereof a number of shares of
Cox Common Stock (subject to the Company's right to deliver, with respect to
all, but not less than all, shares of Cox Common Stock deliverable on the
Maturity Date, cash with an equal value) determined in accordance with the
following formula (the "Payment Rate Formula"), subject to certain adjustments:
(a) if the Maturity Price is greater than or equal to $27.91 per share of Cox
Common Stock (the "Threshold Appreciation Price"), .8196 shares of Cox Common
Stock per STRYPES, (b) if the Maturity Price is less than the Threshold
Appreciation Price but is greater than the Initial Price, a fractional share of
Cox Common Stock per STRYPES so that the value thereof (determined based on the
Maturity Price) equals the Initial Price and (c) if the Maturity Price is less
than or equal to the Initial Price, one share of Cox Common Stock per STRYPES.
The "Maturity Price" means the average Closing Price (as defined herein) per
share of Cox Common Stock on the 20 Trading Days (as defined herein) immediately
prior to the second Trading Day preceding the Maturity Date. ACCORDINGLY, THERE
CAN BE NO ASSURANCE THAT THE AMOUNT RECEIVABLE BY HOLDERS OF THE STRYPES ON THE
MATURITY DATE WILL BE EQUAL TO OR GREATER THAN THE ISSUE PRICE OF THE STRYPES.
IF THE MATURITY PRICE OF THE COX COMMON STOCK IS LESS THAN THE INITIAL PRICE,
SUCH AMOUNT RECEIVABLE ON THE MATURITY DATE WILL BE LESS THAN THE ISSUE PRICE
PAID FOR THE STRYPES, IN WHICH CASE AN INVESTMENT IN THE STRYPES WILL RESULT IN
A LOSS. See "Description of the STRYPES."

   From and after a tax event date (as defined herein), the STRYPES will be
redeemed at the option of the Company, in whole but not in part, at the Tax
Event Redemption Price (as defined herein). See "Description of the STRYPES--
Special Redemption Upon Tax Event." The STRYPES are not subject to any sinking
fund.

   Cox is not affiliated with the Company and has no obligation with respect to
the STRYPES.

                                  RISK FACTORS

COMPARISON TO OTHER DEBT SECURITIES; RELATIONSHIP TO COX COMMON STOCK

  The terms of the STRYPES differ from those of ordinary debt securities in that
the value of the Cox Common Stock (or, pursuant to the option of the Company,
the amount of cash) that a holder of a STRYPES will receive on the Maturity Date
is not fixed, but is based on the Maturity Price of the Cox Common Stock (see
"Description of the STRYPES"). THERE CAN BE NO ASSURANCE THAT SUCH AMOUNT
RECEIVABLE BY THE HOLDER ON THE MATURITY DATE WILL BE EQUAL TO OR GREATER THAN
THE ISSUE PRICE OF THE STRYPES. IF THE MATURITY PRICE OF THE COX COMMON STOCK IS
LESS THAN THE INITIAL PRICE, SUCH AMOUNT RECEIVABLE ON THE MATURITY DATE WILL BE
LESS THAN THE ISSUE PRICE PAID FOR THE STRYPES, IN WHICH CASE AN INVESTMENT IN
STRYPES WILL RESULT IN A LOSS. ACCORDINGLY, A HOLDER OF STRYPES ASSUMES THE RISK
THAT THE MARKET VALUE OF THE COX COMMON STOCK MAY DECLINE, AND THAT SUCH DECLINE
COULD BE SUBSTANTIAL.

LIMITATION ON OPPORTUNITY FOR EQUITY APPRECIATION

  The opportunity for equity appreciation afforded by an investment in the
STRYPES is less than the opportunity for equity appreciation afforded by a
direct investment in the Cox Common Stock because the amount receivable by a
holder of a STRYPES on the Maturity Date will only exceed the issue price of
such STRYPES if the Maturity Price of the Cox Common Stock exceeds the Threshold
Appreciation Price (which represents an appreciation of 22% over the Initial
Price). Moreover, holders of the STRYPES will only be entitled to receive on the
Maturity Date 81.96% (the percentage equal to the Initial Price divided by the
Threshold Appreciation Price) of any appreciation of the value of Cox Common
Stock in excess of the Threshold Appreciation Price. See "Description of the
STRYPES." Because the price of the Cox Common Stock is subject to market
fluctuations, the value of the Cox Common Stock (or, pursuant to the option of
the Company, the amount of cash) received by a holder of a STRYPES on the
Maturity Date, determined as described herein, may be more or less than the
issue price of the STRYPES.

FACTORS AFFECTING TRADING PRICES

  The trading prices of the STRYPES in the secondary market will be directly
affected by the trading prices of the Cox Common Stock in the secondary market.
It is impossible to predict whether the price of Cox Common Stock will rise or
fall. Trading prices of Cox Common Stock will be influenced by Cox's operating
results and prospects, by complex and interrelated political, economic,
financial and other factors and market conditions that can affect the capital
markets generally, the market segment of which Cox is a part, the NYSE (on which
the Cox Common Stock is traded), including the level of, and fluctuations in,
the trading prices of stocks generally and sales of substantial amounts of Cox
Common Stock in the market subsequent to the offering of the STRYPES or the
perception that such sales could occur, and by other events that are difficult
to predict and beyond the Company's control.

IMPACT OF STRYPES ON THE MARKET FOR COX COMMON STOCK
<PAGE>
 
  It is not possible to predict accurately how or whether the STRYPES will trade
in the secondary market or whether such market will be liquid. Any market that
develops for the STRYPES is likely to influence and be influenced by the market
for Cox Common Stock. For example, the price of Cox Common Stock could be
depressed by investors' anticipation of the potential distribution into the
market of substantial amounts of Cox Common Stock on the Maturity Date or upon
redemption of the STRYPES, by possible sales of Cox Common Stock by investors
who view the STRYPES as a more attractive means of equity participation in Cox
and by hedging or arbitrage trading activity that may develop involving the
STRYPES and the Cox Common Stock. In addition, Cox Enterprises, Inc. ("CEI") is
not precluded from selling shares of Cox Common Stock, either pursuant to Rule
144 or by causing Cox to register such shares. Any such sales could have an
adverse effect on the market price of Cox Common Stock and/or the STRYPES and
could affect the Payment Rate Formula.

POSSIBLE ILLIQUIDITY OF THE SECONDARY MARKET

  It is not possible to predict how the STRYPES will trade in the secondary
market or whether such market will be liquid or illiquid. The STRYPES are novel
securities and there is currently no secondary market for the STRYPES. The
STRYPES have been listed on the NYSE. However, there can be no assurance that an
active trading market for the STRYPES will develop, that such listing will
provide the holders of the STRYPES with liquidity of investment, or that the
STRYPES will not later be delisted or that trading of the STRYPES on the NYSE
will not be suspended. In the event of a delisting or suspension of trading on
the NYSE, the Company will apply for listing of the STRYPES on another national
securities exchange or for quotation on another trading market. If the STRYPES
are not listed or traded on any securities exchange or trading market, or if
trading of the STRYPES is suspended, pricing information for the STRYPES may be
more difficult to obtain and the liquidity of the STRYPES may be adversely
affected.

NO STOCKHOLDER'S RIGHTS

  Holders of the STRYPES will not be entitled to any rights with respect to the
Cox Common Stock (including, without limitation, voting rights and rights to
receive any dividends or other distributions in respect thereof) unless and
until such time, if any, as the Company shall have delivered shares of Cox
Common Stock for STRYPES on the Maturity Date or upon redemption, and unless the
applicable record date, if any, for the exercise of such rights occurs after
such date. For example, in the event that an amendment is proposed to the
Certificate of Incorporation of Cox and the record date for determining the
stockholders of record entitled to vote on such amendment occurs prior to such
delivery, holders of the STRYPES will not be entitled to vote on such amendment.

NO AFFILIATION BETWEEN THE COMPANY AND COX

  The Company has no affiliation with Cox, and Cox has no obligations with
respect to the STRYPES or amounts to be paid to holders thereof, including any
obligation to take the needs of the Company or of holders of the STRYPES into
consideration for any reason. Cox will not receive any of the proceeds of the
offering of the STRYPES made hereby and is not responsible for, and has not
participated in, the determination or calculation of the amount receivable by
holders of the STRYPES on the Maturity Date or upon redemption. Cox is not
involved with the administration or trading of the STRYPES and has no
obligations with respect to the amount receivable by holders of the STRYPES on
the Maturity Date or upon redemption.

DILUTION OF COX COMMON STOCK

  The number of shares of Cox Common Stock (or the amount of cash) that holders
of the STRYPES are entitled to receive on the Maturity Date or upon redemption
is subject to adjustment for certain events arising from, among others, a merger
or consolidation in which Cox is not the surviving or resulting corporation, or
a sale or transfer of all or substantially all of the assets of Cox and the
liquidation, dissolution, winding up or bankruptcy of Cox as well as stock
splits and combinations, stock dividends and certain other actions of Cox
<PAGE>
 
that modify its capital structure. See "Description of the STRYPES--Dilution
Adjustments" and "--Special Redemption Upon Tax Event." Such number of shares of
Cox Common Stock (or cash amount) to be received by such holders on the Maturity
Date or upon redemption will not be adjusted for other events, such as offerings
of Cox Common Stock for cash or in connection with acquisitions. Cox is not
restricted from issuing additional shares of Cox Common Stock during the term of
the STRYPES and has no obligation to consider the interests of the holders of
the STRYPES for any reason. Additional issuances may materially and adversely
affect the price of the Cox Common Stock and, because of the relationship of the
number of shares (or cash amount) to be received on the Maturity Date or upon
redemption to the price of the Cox Common Stock, such other events may adversely
affect the trading price of the STRYPES.

TAX MATTERS

  Because of an absence of authority as to the proper characterization of the
STRYPES, their ultimate tax treatment is uncertain. Accordingly, no assurances
can be given that any particular characterization and treatment of the STRYPES
will be accepted by the Internal Revenue Service ("IRS") or upheld by a court.
However, it is the opinion of Brown & Wood LLP, counsel to the Company, that the
characterization and tax treatment of the STRYPES described herein, while not
the only reasonable characterization and tax treatment, is based on reasonable
interpretations of law currently in effect and, even if successfully challenged
by the IRS, will not result in the imposition of penalties. The Indenture (as
defined below) will require that any holder subject to U.S. Federal income tax
include currently in income, for U.S. Federal income tax purposes, payments
denominated as interest that are made with respect to a STRYPES in accordance
with such holder's regular method of tax accounting. The Indenture also requires
the Company and holders to treat each STRYPES for tax purposes as a unit (a
"Unit") consisting of (i) a debt instrument (the "Debt Instrument") with a fixed
principal amount unconditionally payable on the Maturity Date equal to the issue
price of the STRYPES and bearing interest at the stated interest rate on the
STRYPES and (ii) a forward purchase contract (the "Forward Contract") pursuant
to which the holder agrees to use the principal payment due on the Debt
Instrument to purchase on the Maturity Date or upon redemption the Cox Common
Stock which the Company is obligated under the STRYPES to deliver at that time
(subject to the Company's right to deliver cash in lieu of the Cox Common
Stock). The Indenture also requires that upon the acquisition of a STRYPES and
upon a holder's sale or other disposition of a STRYPES prior to the Maturity
Date, the amount paid or realized by the holder be allocated by the holder
between the Debt Instrument and the Forward Contract based upon their relative
fair market values (as determined on the date of acquisition or disposition).
For these purposes, with respect to acquisitions of STRYPES in connection with
the original issuance thereof, the Company and each holder agrees, pursuant to
the terms of the Indenture, to allocate $22.555 of the entire initial purchase
price of a STRYPES (i.e., the issue price of a STRYPES) to the Debt Instrument
and to allocate the remaining $.32 of the entire initial purchase price of a
STRYPES to the Forward Contract. As a result of this allocation, the Debt
Instrument will be treated as having been issued with original issue discount
for United States Federal income tax purposes. As previously mentioned, the
appropriate character and timing of income, gain or loss to be recognized on a
STRYPES is uncertain and investors should consult their own tax advisers
concerning the application of the United States Federal income tax laws to their
particular situations as well as any consequences of the purchase, ownership and
disposition of the STRYPES arising under the laws of any other taxing
jurisdiction.

HOLDING COMPANY STRUCTURE

  Since the Company is a holding company, the right of the Company, and hence
the right of creditors of the Company (including the holders of the STRYPES), to
participate in any distribution of the assets of any subsidiary upon its
liquidation or reorganization or otherwise is necessarily subject to the prior
claims of creditors of the subsidiary, except to the extent that claims of the
Company itself as a creditor of the subsidiary may be recognized. In addition,
dividends, loans and advances from certain subsidiaries, including MLPF&S, to
the Company are restricted by net capital requirements under the Exchange Act
and under rules of certain exchanges and other regulatory bodies.

IT INCORPORATED BY REFERENCE HEREIN OR THEREIN.


                           DESCRIPTION OF THE STRYPES

  The STRYPES are a series of Senior Debt Securities issued under an indenture
dated as of April 1, 1983 and restated as of April 1, 1987, as amended and
supplemented as of July 1, 1995 (the indenture dated as of April 1, 1983 and
restated as of April 1, 1987, as amended and supplemented from time to time, the
"Indenture") between the Company and The Chase Manhattan Bank, formerly known as
Chemical Bank (successor by merger to Manufacturers Hanover Trust Company), as
trustee (the "Trustee"). The following summary of certain provisions of the
Indenture does not purport to be complete and is qualified in its entirety by
reference to the Indenture, a copy of which is filed as an exhibit to the
Registration Statement of which this Prospectus is a part. All capitalized terms
not otherwise defined herein have the meanings specified in the Indenture.
Whenever defined terms of the Indenture are referred to herein, such defined
terms are incorporated by reference herein.

GENERAL

  Each STRYPES, which was issued at a price of $22.875, bears interest at the
rate of 6% of the issue price per annum (or $1.37 per annum) from May 29, 1996,
or from the most recent Interest Payment Date to which interest has been paid or
provided for, until the Maturity Date or such earlier date on which such STRYPES
is redeemed or the issue price of such STRYPES is repaid pursuant to the terms
thereof. Interest on the STRYPES will be payable in cash quarterly in arrears on
March 1, June 1, September 1 and December 1, beginning September 1, 1996, and on
the Maturity Date (each, an "Interest Payment Date"), to the persons in whose
names the STRYPES are registered at the close of business on the last day
(whether or not a Business Day) of the calendar month immediately preceding such
Interest Payment Date. Interest on the STRYPES will be computed on the basis of
a 360-day year of twelve 30-day months. If an Interest Payment Date falls on a
day that is not a Business Day, the interest payment to be made on such Interest
Payment Date will be made on the next succeeding Business Day with the same
force and effect as if made on such Interest Payment Date, and no additional
interest will accrue as a result of such delayed payment.

  The STRYPES will mature on June 1, 1999. On the Maturity Date, unless
previously redeemed, the Company will pay and discharge each STRYPES by
delivering to the holder thereof a number of shares (such number of shares being
hereinafter referred to as the "Payment Rate") of Cox Common Stock (subject to
the Company's right to deliver, with respect to all, but not less than all,
shares of Cox Common Stock deliverable on the Maturity Date, cash with an equal
value) determined in accordance with the following "Payment Rate Formula,"
subject to adjustment as a result of certain dilution events: (a) if the
Maturity Price (as defined below) per share of Cox
<PAGE>
 
Common Stock is greater than or equal to the Threshold Appreciation Price, .8196
shares of Cox Common Stock per STRYPES, (b) if the Maturity Price is less than
the Threshold Appreciation Price but is greater than the Initial Price, a
fractional share of Cox Common Stock per STRYPES so that the value thereof
(determined based on the Maturity Price) is equal to the Initial Price and (c)
if the Maturity Price is less than or equal to the Initial Price, one share of
Cox Common Stock per STRYPES. ACCORDINGLY, THERE CAN BE NO ASSURANCE THAT THE
AMOUNT RECEIVABLE BY HOLDERS OF THE STRYPES ON THE MATURITY DATE WILL BE EQUAL
TO OR GREATER THAN THE ISSUE PRICE OF THE STRYPES. IF THE MATURITY PRICE OF THE
COX COMMON STOCK IS LESS THAN THE INITIAL PRICE, SUCH AMOUNT RECEIVABLE ON THE
MATURITY DATE WILL BE LESS THAN THE ISSUE PRICE PAID FOR THE STRYPES, IN WHICH
CASE AN INVESTMENT IN STRYPES WILL RESULT IN A LOSS. The numbers of shares of
Cox Common Stock per STRYPES specified in clauses (a) and (c) of the Payment
Rate Formula are hereinafter referred to as the "Share Components."

  Notwithstanding the foregoing, the Company may, in lieu of delivering shares
of Cox Common Stock, deliver cash in an amount equal to the value of such number
of shares of Cox Common Stock at the Maturity Price, subject to the Company's
agreement contained in the STRYPES Agreement to deliver on the Maturity Date the
form of consideration that the ML&Co. Subsidiary (as defined below) receives
from CEI. Such right, if exercised by the Company, must be exercised with
respect to all shares of Cox Common Stock otherwise deliverable on the Maturity
Date in payment of all outstanding STRYPES. On or prior to the sixth Business
Day prior to the Maturity Date, the Company will notify The Depository Trust
Company and the Trustee and publish a notice in The Wall Street Journal or
another daily newspaper of national circulation stating whether the STRYPES will
be paid and discharged with shares of Cox Common Stock or cash. At the time such
notice is published, the Maturity Price will not have been determined. If the
Company elects to deliver shares of Cox Common Stock, holders of the STRYPES
will be responsible for the payment of any and all brokerage costs upon the
subsequent sale of such stock.

  The "Maturity Price" is defined as the sum of (A) the average Closing Price
per share of Cox Common Stock on the 20 Trading Days immediately prior to, but
not including, the second Trading Day preceding the Maturity Date and (B) the
fair market value (as determined by the Board of Directors of the Company, whose
determination shall be conclusive, and described in a resolution adopted with
respect thereto) as of the third Trading Day preceding the Maturity Date of the
Distributed Assets (as defined below) applicable to one share of Cox Common
Stock. The "Closing Price" of any security on any date of determination means
the closing sale price (or, if no closing price is reported, the last reported
sale price) of such security on the NYSE on such date or, if such security is
not listed for trading on the NYSE on any such date, as reported in the
composite transactions for the principal United States securities exchange on
which such security is so listed, or if such security is not so listed on a
United States national or regional securities exchange, as reported by the
National Association of Securities Dealers, Inc. Automated Quotation System, or,
if such security is not so reported, the last quoted bid price for such security
in the over-the-counter market as reported by the National Quotation Bureau or
similar organization, or, if such bid price is not available, the market value
of such security on such date as determined by a nationally recognized
independent investment banking firm retained for this purpose by the Company. In
the event that the Payment Rate Formula is adjusted as described under "--
Dilution Adjustments" below, each of the Closing Prices used in determining the
Maturity Price will be similarly adjusted to derive, for purposes of determining
which of clauses (a), (b) or (c) of the Payment Rate Formula will apply on the
Maturity Date, a Maturity Price stated on a basis comparable to the Initial
Price and the Threshold Appreciation Price. A "Trading Day" is defined as a day
on which the security the Closing Price of which is being determined (A) is not
suspended from trading on any national or regional securities exchange or
association or over-the-counter market at the close of business and (B) has
traded at least once on the national or regional securities exchange or
association or over-the-counter market that is the primary market for the
trading of such security.

  For illustrative purposes only, the following table shows the number of shares
of Cox Common Stock or the amount of cash that a holder of STRYPES would receive
for each STRYPES at various Maturity Prices. The table assumes that there will
be no dilution adjustments to the Payment Rate Formula as described below. There
can be no assurance that the Maturity Price will be within the range set forth
below. Given the Initial Price of $22.875 and the Threshold Appreciation Price
of $27.91, a STRYPES holder would receive on the Maturity Date the following

DILUTION ADJUSTMENTS

  The Payment Rate Formula is subject to adjustment if Cox shall: (i) pay a
stock dividend or make a distribution with respect to Cox Common Stock in shares
of such stock; (ii) subdivide or split the outstanding shares of Cox Common
Stock into a greater number of shares; (iii) combine the outstanding shares of
Cox Common Stock into a smaller number of shares; (iv) issue by reclassification
of shares of Cox Common Stock any shares of common stock of Cox; (v) issue
rights or warrants to all holders of Cox Common Stock entitling them to
subscribe for or purchase shares of Cox Common Stock at a price per share less
than the then current market price of the Cox Common Stock (other than rights to
purchase Cox Common Stock pursuant to a plan for the reinvestment of dividends
or interest); or (vi) pay a dividend or make a distribution to all holders of
Cox Common Stock of evidences of its indebtedness or other assets (excluding any
stock dividends or distributions referred to in clause (i) above or any cash
dividends other than any Extraordinary Cash Dividend (as defined below)) or
issue to all holders of Cox Common Stock rights or warrants to subscribe for or
purchase any of its securities (other than those referred to in clause (v)
above) (any of the foregoing are referred to as the "Distributed Assets"). The
effect of the foregoing is that there will not be any adjustments to the Payment
Rate Formula for the issuance by Cox of options, warrants, stock purchase rights
or securities in connection with Cox's employee benefit plans.

  In the case of the events referred to in clauses (i), (ii), (iii) and (iv)
above, the Payment Rate Formula shall be adjusted so that each holder of any
STRYPES shall thereafter be entitled to receive, upon payment and discharge or
redemption of such STRYPES, the number of shares of Cox Common Stock which such
holder would have owned or been entitled to receive immediately following any
such event had such STRYPES been paid and discharged or redeemed immediately
prior to such event or any record date with respect thereto.

  In the case of the event referred to in clause (v) above, the Payment Rate
Formula shall be adjusted by multiplying each of the Share Components in the
Payment Rate Formula in effect immediately prior to the date of issuance of the
rights or warrants referred to in clause (v) above by a fraction, the numerator
of which shall be the number of shares of Cox Common Stock outstanding on the
date of issuance of such rights or warrants, immediately prior to such issuance,
plus the number of additional shares of Cox Common Stock offered for
subscription or purchase pursuant to such rights or warrants, and the
denominator of which shall be the number of shares of Cox Common Stock
outstanding on the date of issuance of such rights or warrants, immediately
prior to such issuance, plus the number of additional shares of Cox Common Stock
which the aggregate offering price of the total number of shares of Cox Common
Stock so offered for subscription or purchase pursuant to such rights or
warrants would purchase at the current market price (determined as the average
Closing Price per share of Cox Common Stock on the 20 Trading Days immediately
prior to the date such rights or warrants are issued, subject to certain
adjustments), which shall be determined by multiplying such total number of
shares by the exercise price of such rights or warrants and dividing the product
so obtained by such current market price. To the extent that shares of Cox
Common Stock are not delivered after the expiration of such rights or warrants,
or if such rights or warrants are
<PAGE>
 
not issued, the Payment Rate Formula shall be readjusted to the Payment Rate
Formula which would then be in effect had such adjustments for the issuance of
such rights or warrants been made upon the basis of delivery of only the number
of shares of Cox Common Stock actually delivered.

  In the case of the event referred to in clause (vi) above, the Payment Rate
Formula shall be adjusted by multiplying each of the Share Components in the
Payment Rate Formula in effect on the record date by a fraction, the numerator
of which shall be the market price per share of the Cox Common Stock on the
record date for the determination of stockholders entitled to receive the
dividend or distribution referred to in clause (vi) above (such market price
being determined as the average Closing Price per share of Cox Common Stock on
the 20 Trading Days immediately prior to such record date, subject to certain
adjustments), and the denominator of which shall be such market price per share
of Cox Common Stock less the fair market value (as determined by the Board of
Directors of the Company, whose determination shall be conclusive, and described
in a resolution adopted with respect thereto) as of such record date of the
portion of the Distributed Assets so distributed applicable to one share of Cox
Common Stock; provided, however, that in the event that the then fair market
value (as so determined) of the portion of the Distributed Assets so distributed
applicable to one share of Cox Common Stock is equal to or greater than the
market price per share of Cox Common Stock as of such record date, in lieu of
the foregoing adjustment, the Company shall reserve such Distributed Assets (or,
in the case of Distributed Assets of a kind described in (z) below, an amount in
cash equal to the fair market value thereof, determined in the manner and as of
the date described in clause (z) below) for delivery to the holders of the
STRYPES on the Maturity Date and, on the Maturity Date, shall deliver to each
such holder, in addition to the shares of Cox Common Stock (or cash in lieu
thereof) to which such holder is otherwise entitled, (x) in respect of that
portion, if any, of the Distributed Assets consisting of cash, the amount of
such Distributed Assets consisting of cash which such holder would have received
had each STRYPES held by such holder been paid and discharged immediately prior
to the record date for the determination of stockholders entitled to receive
such dividend or distribution or such rights or warrants, without interest, plus
(y) in respect of that portion, if any, of the Distributed Assets consisting of
securities for which there is an actual or when issued trading market
("marketable securities"), the amount of such Distributed Assets consisting of
marketable securities which such holder would have received had each STRYPES
held by such holder been paid and discharged immediately prior to the record
date for the determination of stockholders entitled to receive such dividend or
distribution or such rights or warrants, plus (z) in respect of that portion, if
any, of the Distributed Assets which are of a kind other than that described in
clause (x) or (y) above, an amount in cash equal to the fair market value (as
determined by the Board of Directors of the Company, whose determination shall
be conclusive, and described in a resolution adopted with respect thereto), as
of the record date for determination of stockholders entitled to receive such
dividend or distribution or such rights or warrants, of the Distributed Assets
consisting of other assets which such holder would have received had each
STRYPES held by such holder been paid and discharged immediately prior to such
record date, without interest thereon.

  An "Extraordinary Cash Dividend" means, with respect to any consecutive 12-
month period, all cash dividends on the Cox Common Stock during such period to
the extent such dividends exceed on a per share basis 10% of the average Closing
Price of the Cox Common Stock over such period (less any such dividends for
which a prior adjustment to the Payment Rate Formula was previously made). All
adjustments to the Payment Rate Formula will be calculated to the nearest
1/10,000th of a share of Cox Common Stock (or if there is not a nearest
1/10,000th of a share to the next lower 1/10,000th of a share). No adjustment in
the Payment Rate Formula shall be required unless such adjustment would require
an increase or decrease of at least one percent therein; provided, however, that
any adjustments which by reason of the foregoing are not required to be made
shall be carried forward and taken into account in any subsequent adjustment. If
an adjustment is made to the Payment Rate Formula as described above, an
adjustment will also be made to the Maturity Price solely to determine which of
clauses (a), (b) or (c) of the Payment Rate Formula will apply on the Maturity
Date. The required adjustment to the Maturity Price will be made by multiplying
each of the Closing Prices used in determining the Maturity Price by a fraction,
the numerator of which shall be the Share Component in clause (c) of the Payment
Rate Formula immediately after such adjustment described above, and the
denominator of which shall be the Share Component in clause (c) of the
<PAGE>
 
Payment Rate Formula immediately before such adjustment described above. Each
such adjustment to the Payment Rate Formula shall be made successively.

  In the event of (A) any consolidation or merger of Cox, or any surviving
entity or subsequent surviving entity of Cox (a "Cox Successor"), with or into
another entity (other than a merger or consolidation in which Cox is the
continuing corporation and in which the Cox Common Stock outstanding immediately
prior to the merger or consolidation is not exchanged for cash, securities or
other property of Cox or another corporation), (B) any sale, transfer, lease or
conveyance to another corporation of the property of Cox or any Cox Successor as
an entirety or substantially as an entirety, (C) any statutory exchange of
securities of Cox or any Cox Successor with another corporation (other than in
connection with a merger or acquisition) or (D) any liquidation, dissolution,
winding up or bankruptcy of Cox or any Cox Successor (any such event described
in clause (A), (B), (C) or (D), a "Reorganization Event"), the Payment Rate
Formula used to determine the amount payable on the Maturity Date for each
STRYPES will be adjusted to provide that each holder of STRYPES will receive on
the Maturity Date for each STRYPES cash in an amount equal to (a) if the
Transaction Value (as defined below) is greater than or equal to the Threshold
Appreciation Price, .8196 multiplied by the Transaction Value, (b) if the
Transaction Value is less than the Threshold Appreciation Price but greater than
the Initial Price, the Initial Price and (c) if the Transaction Value is less
than or equal to the Initial Price, the Transaction Value. "Transaction Value"
means (i) for any cash received in any such Reorganization Event, the amount of
cash received per share of Cox Common Stock, (ii) for any property other than
cash or securities received in any such Reorganization Event, an amount equal to
the market value on the Maturity Date of such property received per share of Cox
Common Stock as determined by a nationally recognized independent investment
banking firm retained for this purpose by the Company and (iii) for any
securities received in any such Reorganization Event, an amount equal to the
average Closing Price per unit of such securities on the 20 Trading Days
immediately prior to the second Trading Day preceding the Maturity Date
multiplied by the number of such securities received for each share of Cox
Common Stock. Notwithstanding the foregoing, in the event that property or
securities, or a combination of cash, on the one hand, and property or
securities, on the other, are received in such Reorganization Event, the Company
may, in lieu of delivering cash as described above, deliver the amount of cash,
securities and other property received per share of Cox Common Stock in such
Reorganization Event determined in accordance with clause (i), (ii) or (iii)
above, as applicable. If the Company elects to deliver securities or other
property, holders of the STRYPES will be responsible for the payment of any and
all brokerage and other transaction costs upon any subsequent sale of such
securities or other property. The kind and amount of securities with which the
STRYPES shall be paid and discharged after consummation of such transaction
shall be subject to adjustment as described above following the date of
consummation of such transaction.

  No adjustments will be made for certain other events, such as offerings of Cox
Common Stock by Cox for cash or in connection with acquisitions. Likewise, no
adjustments will be made for any sales of Cox Common Stock by CEI.

  The Company is required, within ten Business Days following the occurrence of
an event that requires an adjustment to the Payment Rate Formula (or if the
Company is not aware of such occurrence, as soon as practicable after becoming
so aware), to provide written notice to the Trustee and to the holders of the
STRYPES of the occurrence of such event and a statement in reasonable detail
setting forth the adjusted Payment Rate Formula and the method by which the
adjustment to the Payment Rate Formula was determined, provided that, in respect
of any adjustment to the Maturity Price, such notice will only disclose the
factor by which each of the Closing Prices used in determining the Maturity
Price is to be multiplied in order to determine the Payment Rate on the Maturity
Date. Until the Maturity Date, the Payment Rate itself cannot be determined.

FRACTIONAL SHARES

  No fractional shares of Cox Common Stock will be delivered if the Company pays
and discharges the STRYPES by delivering shares of Cox Common Stock. In lieu of
any fractional share otherwise deliverable in respect of all STRYPES of any
holder on the Maturity Date, such holder shall be entitled to receive an amount
in cash equal to the value of such fractional share at the Maturity Price.
<PAGE>
 
SPECIAL REDEMPTION UPON TAX EVENT

  The STRYPES will be redeemable at the option of the Company, in whole but not
in part, at any time from and after the date (the "Tax Event Date") on which a
Tax Event (as defined below) shall occur at a price per STRYPES (the "Tax Event
Redemption Price") equal to (a) an amount of cash equal to the sum of (i) all
accrued and unpaid interest on such STRYPES to the date fixed for redemption
(the "Redemption Date"), (ii) the sum of all interest payments on such STRYPES
due after the Redemption Date and on or prior to the Maturity Date and (iii)
$1.37 (equal to the interest payable on such STRYPES for one year), plus (b) a
number of shares of Cox Common Stock determined in accordance with the Payment
Rate Formula, with the Redemption Date being deemed to be the Maturity Date for
purposes of calculating the Maturity Price.

  A "Tax Event" means that CEI shall have delivered to the Company an opinion
(the "Tax Event Opinion") from independent tax counsel experienced in such
matters to the effect that, as a result of (a) any amendment or proposed
amendment to, or change (including any announced prospective change) or proposed
change in, the laws (or any regulations thereunder) of the United States or any
taxing authority thereof or therein or (b) any amendment to, or change in, an
interpretation or application of such laws or regulations by any legislative
body, court, governmental agency or regulatory authority, enacted, promulgated,
introduced, issued or announced or which interpretation is issued or announced
or which action is taken, on or after the date of this Prospectus Supplement,
there is more than an insubstantial risk that a corporation that sells or
otherwise disposes of stock in another corporation on a date that is after the
date of this Prospectus Supplement and that is on or prior to the Maturity Date
would not be permitted to specifically identify the stock sold or disposed of
for purposes of determining the amount of such corporation's gain or loss on the
stock sold or disposed of for United States Federal income tax purposes.

  On March 19, 1996, the U.S. Treasury Department proposed a series of tax law
changes as part of President Clinton's 1997 Budget proposal. These proposed tax
law changes would, among other things, require taxpayers (including
corporations) that sell or otherwise dispose of securities (which term includes
stock in a corporation) that are substantially identical to securities which
they continue to hold to determine their tax basis in such substantially
identical securities using the average basis of all of their holdings in the
securities, and would prevent such taxpayers from specifically identifying the
securities sold or disposed of for purposes of determining the amount of their
gain or loss on the securities sold or disposed of for United States Federal
income tax purposes. As originally proposed, this "average cost basis" rule
would apply to determinations (i.e., tax basis determinations made at the time
of sale or disposition) made more than 30 days after the date on the which the
proposal is enacted. Thus, if this "average cost basis" rule is ultimately
adopted in its current form on a date that is 31 or more days prior to the
Maturity Date, such enactment could result in a Tax Event. Furthermore, if there
are future legislative developments such that as a result thereof there is more
than an insubstantial risk that this "average cost basis" rule or a provision
with similar effect will be adopted and effective for determinations made on or
prior to the Maturity Date, such legislative developments could result in a Tax
Event. The Company cannot predict whether or not these proposed tax law changes
will ultimately become law. Moreover, the Company cannot predict whether or not
any other future change or proposed change in the tax law will occur which could
give rise to a Tax Event, nor can it predict whether CEI will elect to cause a
Tax Event by delivering the Tax Event Opinion to the Company in the event that a
change or proposed change in the tax law occurs which could give rise to a Tax
Event.

  The Company will provide notice of any call for redemption of STRYPES to
holders of record of the STRYPES not less than 10 nor more than 30 calendar days
prior to the related Redemption Date. Such notice will state the following and
may contain such other information as the Company deems advisable: (a) the
Redemption Date; (b) the place or places where certificates for the STRYPES are
to be surrendered for redemption and (c) that interest will cease to accrue on
the STRYPES on the Redemption Date (except as otherwise provided in the
Indenture). Any such notice will be provided by mail, sent to each holder of
record of STRYPES at such holder's address as it appears on the security
register for the STRYPES, first class postage prepaid; provided, however, that
failure to give such notice or any defect therein shall not affect the validity
of the proceeding for redemption of any STRYPES except as to the holder to whom
the Company has failed to give said notice or whose notice was
<PAGE>
 
defective. At or prior to the mailing of such notice of redemption, the Company
will publish a public announcement of redemption in The Wall Street Journal or
another daily newspaper of national circulation.

  The Company will not be required to deliver any fractional share of Cox Common
Stock on the Redemption Date and, in lieu thereof, will pay an amount in cash
equal to the value of such fractional share of Cox Common Stock based on the
average Closing Price per share of Cox Common Stock on the 20 Trading Days
immediately prior to, but not including, the second Trading Day preceding the
Redemption Date.

  On and after the Redemption Date, all rights of a holder of STRYPES will
terminate except the right to receive for each STRYPES so redeemed the Tax Event
Redemption Price (unless there is a default on the payment of such Tax Event
Redemption Price).



NO SINKING FUND

  The STRYPES do not contain sinking fund or other mandatory redemption
provisions. The STRYPES are not subject to payment prior to the Maturity Date at
the option of the holder.

RANKING

  The STRYPES will be unsecured obligations and will rank pari passu with all
other unsecured and unsubordinated indebtedness of the Company.

  There are no contractual restrictions on the ability of the Company or its
subsidiaries to incur additional secured or unsecured debt. However, borrowings
by certain subsidiaries, including MLPF&S, are restricted by net capital
requirements under the Exchange Act and under rules of certain exchanges and
other regulatory bodies.

SECURITIES DEPOSITORY

  Upon issuance, each series of STRYPES will be represented by one or more fully
registered global securities (the "Global Notes"). Each such Global Note will be
deposited with, or on behalf of, The Depository Trust Company, as Securities
Depository (the "Securities Depository"), and registered in the name of the
Securities Depository or a nominee thereof. Unless and until it is exchanged in
whole or in part for STRYPES in definitive form under the limited circumstances
described below, no Global Note may be transferred except as a whole by the
Securities Depository to a nominee of such Securities Depository or by a nominee
of such Securities Depository to such Securities Depository or another nominee
of such Securities Depository or by such Securities Depository or any such
nominee to a successor of such Securities Depository or a nominee of such
successor.

  The Securities Depository has advised the Company as follows: The Securities
Depository is a limited-purpose trust company organized under the Banking Law of
the State of New York, a member of the Federal Reserve System, a "clearing
corporation" within the meaning of the New York Uniform Commercial Code, and a
"clearing agency" registered pursuant to the provisions of Section 17A of the
Exchange Act. The Securities Depository was created to hold securities of its
participants ("Participants") and to facilitate the clearance and settlement of
securities transactions among its Participants in such securities through
electronic book-entry changes in accounts of the Participants, thereby
eliminating the need for physical movement of securities certificates. The
Securities Depository's Participants include securities brokers and dealers
(including MLPF&S), banks, trust companies, clearing corporations, and certain
other organizations.

  The Securities Depository is owned by a number of Participants and by the New
York Stock Exchange, Inc., the American Stock Exchange, Inc. and the National
Association of Securities Dealers, Inc. Access to the Securities
<PAGE>
 
Depository's book-entry system is also available to others, such as banks,
brokers, dealers and trust companies that clear through or maintain a custodial
relationship with a Participant, either directly or indirectly ("Indirect
Participants").

  Purchases of STRYPES must be made by or through Participants, which will
receive a credit on the records of the Securities Depository. The ownership
interest of each actual purchaser of each STRYPES ("Beneficial Owner") is in
turn to be recorded on the Participants' or Indirect Participants' records.
Beneficial Owners will not receive written confirmations from the Securities
Depository of their purchase, but Beneficial Owners are expected to receive
written confirmation providing details of the transaction, as well as periodic
statements of their holdings, from the Participant or Indirect Participant
through which the Beneficial Owner entered into the transaction. Ownership of
beneficial interest in such Global Note will be shown on, and the transfer of
such ownership interests will be effected only through, records maintained by
the Securities Depository (with respect to interests of Participants) and on the
records of Participants (with respect to interests of persons held through
Participants). The laws of some states may require that certain purchasers of
securities take physical delivery of such securities in definitive form. Such
limits and such laws may impair the ability to own, transfer or pledge
beneficial interests in Global Notes.

  So long as the Securities Depository, or its nominee, is the registered owner
of a Global Note, the Securities Depository or its nominee, as the case may be,
will be considered the sole owner or holder of the STRYPES represented by such
Global Note for all purposes under the Indenture. Except as provided below,
Beneficial Owners in a Global Note will not be entitled to have the STRYPES
represented by such Global Notes registered in their names, will not receive or
be entitled to receive physical delivery of the STRYPES in definitive form and
will not be considered the owners or holders thereof under the Indenture.
Accordingly, each Person owning a beneficial interest in a Global Note must rely
on the procedures of the Securities Depository and, if such Person is not a
Participant, on the procedures of the Participant through which such Person owns
its interest, to exercise any rights of a holder under the Indenture. The
Company understands that under existing industry practices, in the event that
the Company requests any action of holders or that an owner of a beneficial
interest in such a Global Note desires to give or take any action which a holder
is entitled to give or take under the Indenture, the Securities Depository would
authorize the Participants holding the relevant beneficial interests to give or
take such action, and such Participants would authorize Beneficial Owners owning
through such Participants to give or take such action or would otherwise act
upon the instructions of Beneficial Owners. Conveyance of notices and other
communications by the Securities Depository to Participants, by Participants to
Indirect Participants, and by Participants and Indirect Participants to
Beneficial Owners will be governed by arrangements among them, subject to any
statutory or regulatory requirements as may be in effect from time to time.

  Payment of any amount with respect to STRYPES registered in the name of the
Securities Depository or its nominee will be made to the Securities Depository
or its nominee, as the case may be, as the holder of the Global Notes
representing such STRYPES. None of the Company, the Trustee or any other agent
of the Company or agent of the Trustee will have any responsibility or liability
for any aspect of the records relating to or payments made on account of
beneficial ownership interests or for supervising or reviewing any records
relating to such beneficial ownership interests. The Company expects that the
Securities Depository, upon receipt of any payment in respect of a Global Note,
will credit the accounts of the Participants with payment in amounts
proportionate to their respective holdings of beneficial interest in such Global
Note as shown on the records of the Securities Depository. The Company also
expects that payments by Participants to Beneficial Owners will be governed by
standing customer instructions and customary practices, as is now the case with
securities held for the accounts of customers in bearer form or registered in
"street name," and will be the responsibility of such Participants.

  If, with respect to a series of STRYPES, (x) the Securities Depository is at
any time unwilling or unable to continue as Securities Depository and a
successor depository is not appointed by the Company within 60 days, (y) the
Company executes and delivers to the Trustee a Company Order to the effect that
the Global Notes shall be exchangeable or (z) an Event of Default has occurred
and is continuing with respect to any STRYPES of that series,
<PAGE>
 
the Company will issue STRYPES in definitive form in exchange for all of the
Global Notes representing the STRYPES of that series. Such definitive STRYPES
shall be registered in such name or names as the Securities Depository shall
instruct the Trustee. It is expected that such instructions may be based upon
directions received by the Securities Depository from Participants with respect
to ownership of beneficial interests in such Global Notes.

MERGER AND CONSOLIDATION

  The Company may consolidate or merge with or into any other corporation, and
the Company may sell, lease or convey all or substantially all of its assets to
any corporation, provided that (i) the corporation (if other than the Company)
formed by or resulting from any such consolidation or merger or which shall have
received such assets shall be a corporation organized and existing under the
laws of the United States of America or a state thereof and shall assume the due
and punctual delivery or payment of the Underlying Securities (or cash with an
equal value) in respect of, any interest and Additional Amounts on, and any
other amounts payable with respect to, the STRYPES of each series and the due
and punctual performance and observance of all of the covenants and conditions
of the Indenture to be performed or observed by the Company, and (ii) the
Company or such successor corporation, as the case may be, shall not immediately
thereafter be in default under the Indenture.

LIMITATIONS UPON LIENS

  The Indenture provides that the Company may not, and may not permit any
Subsidiary (defined in the Indenture as any corporation of which at the time of
determination the Company and/or one or more Subsidiaries owns or controls
directly or indirectly 50% of the shares of Voting Stock of such corporation)
to, create, assume, incur or permit to exist any indebtedness for borrowed money
secured by a pledge, lien or other encumbrance (except for certain liens
specifically permitted by the Indenture) on the Voting Stock owned directly or
indirectly by the Company of any Subsidiary (other than a Subsidiary which, at
the time of incurrence of such secured indebtedness, has a net worth of less
than $3,000,000) without making effective provision whereby the Outstanding
STRYPES will be secured equally and ratably with such secured indebtedness.

LIMITATIONS ON DISPOSITION OF VOTING STOCK OF, AND MERGER AND SALE OF ASSETS BY,
MLPF&S

  The Indenture provides that the Company may not sell, transfer or otherwise
dispose of any Voting Stock of MLPF&S or permit MLPF&S to issue, sell or
otherwise dispose of any of its Voting Stock, unless, after giving effect to any
such transaction, MLPF&S remains a Controlled Subsidiary (defined in the
Indenture to mean a corporation more than 80% of the outstanding shares of
Voting Stock of which are owned directly or indirectly by the Company). In
addition, the Indenture provides that the Company may not permit MLPF&S to (i)
merge or consolidate, unless the surviving company is a Controlled Subsidiary,
or (ii) convey or transfer its properties and assets substantially as an
entirety, except to one or more Controlled Subsidiaries.

EVENTS OF DEFAULT

  Each of the following will constitute an Event of Default under the Indenture
with respect to each series of STRYPES: (a) failure to pay and discharge the
STRYPES of that series with the Underlying Securities or, if the Company so
elects, to pay an equivalent amount in cash in lieu thereof when due; (b)
failure to pay the Redemption Price or any redemption premium with respect to
any STRYPES of that series when due; (c) failure to deposit any sinking fund
payment, when and as due by the terms of any STRYPES of that series; (d) failure
to pay any interest on or any Additional Amounts in respect of any STRYPES of
that series when due, continued for 30 days; (e) failure to perform any other
covenant of the Company contained in the Indenture for the benefit of that
series or in the STRYPES of that series, continued for 60 days after written
notice has been given to the Company by the Trustee, or to the Company and the
Trustee by the holders of at least 10% of the aggregate issue price of the
Outstanding STRYPES of that series, as provided in the Indenture; (f) certain
events in bankruptcy, insolvency or reorganization of the Company; and (g) any
other Event of Default provided with respect to STRYPES of that series.
<PAGE>
 
  If an Event of Default (other than an Event of Default described in clause (f)
of the immediately preceding paragraph) with respect to the STRYPES of any
series shall occur and be continuing, either the Trustee or the holders of at
least 25% of the aggregate issue price of the Outstanding STRYPES of that series
by notice as provided in the Indenture may declare an amount equal to the
aggregate issue price of all the STRYPES of that series and the interest accrued
thereon and Additional Amounts payable in respect thereof, if any, to be
immediately due and payable in cash. If an Event of Default described in said
clause (f) shall occur, an amount equal to the aggregate issue price of all the
STRYPES of that series and the interest accrued thereon and Additional Amounts
payable in respect thereof, if any, will become immediately due and payable in
cash without any declaration or other action on the part of the Trustee or any
holder. After such acceleration, but before a judgment or decree based on
acceleration, the holders of a majority of the aggregate issue price of the
Outstanding STRYPES of that series may, under certain circumstances, rescind and
annul such acceleration if all Events of Default, other than the non-payment of
the amount equal to the aggregate issue price of all the STRYPES of that series
due by reason of such acceleration, have been cured or waived as provided in the
Indenture. See "Modification and Waiver" below.

  Subject to the provisions of the Indenture relating to the duties of the
Trustee, in case an Event of Default shall occur and be continuing, the Trustee
will be under no obligation to exercise any of its rights or powers under the
Indenture at the request or direction of any of the holders of STRYPES of any
series, unless such holders of that series shall have offered to the Trustee
reasonable security or indemnity against the costs, expenses and liabilities
which might be incurred by it in compliance with such request or direction.
Subject to such provisions for the indemnification of the Trustee, the holders
of a majority of the aggregate issue price of the STRYPES of any series 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 STRYPES of that series.

  The Company will be required to furnish to the Trustee annually a statement by
certain of its officers as to whether or not the Company, to their knowledge, is
in default in the fulfillment of any of its obligations under the Indenture and,
if so, specifying all such known defaults.

  The STRYPES and other series of Senior Debt Securities issued under the
Indenture will not have the benefit of any cross-default provisions with other
indebtedness of the Company.

MODIFICATION AND WAIVER

  Modifications of and amendments to the Indenture affecting a series of STRYPES
may be made by the Company and the Trustee with the consent of the holders of
66/2//3% of the aggregate issue price of the Outstanding STRYPES of such series;
provided, however, that no such modification or amendment may, without the
consent of the holder of each Outstanding STRYPES of such series affected
thereby, (a) change the Maturity Date or the Stated Maturity of any installment
of interest or Additional Amounts on any STRYPES or any premium payable on the
redemption thereof, or change the Redemption Price, (b) reduce the amount of
Underlying Securities payable with respect to any STRYPES (or reduce the amount
of cash payable in lieu thereof), (c) reduce the amount of interest or
Additional Amounts payable on any STRYPES or reduce the amount of cash payable
with respect to any STRYPES upon acceleration of the maturity thereof, (d)
change the place or currency of payment of interest or Additional Amounts on, or
any amount of cash payable with respect to, any STRYPES, (e) impair the right to
institute suit for the enforcement of any payment on or with respect to any
STRYPES, including the payment of Underlying Securities with respect to any
STRYPES, (f) reduce the percentage of the aggregate issue price of Outstanding
STRYPES of such series, the consent of whose holders is required to modify or
amend the Indenture, (g) reduce the percentage of the aggregate issue price of
Outstanding STRYPES of such series necessary for waiver of compliance with
certain provisions of the Indenture or for waiver of certain defaults or (h)
modify such provisions with respect to modification and waiver. Except as
provided in the Indenture, no modification of or amendment to the Indenture may
adversely affect the rights of a holder of any other Senior Debt Security
without the consent of such holder.
<PAGE>
 
  The holders of a majority of the aggregate issue price of each series of
STRYPES may waive compliance by the Company with certain restrictive provisions
of the Indenture. The holders of a majority of the aggregate issue price of each
series of STRYPES may waive any past default under the Indenture, except a
default in the payment of the Underlying Securities with respect to any STRYPES
of that series, or of cash payable in lieu thereof, or in the payment of any
premium, interest or Additional Amounts on any STRYPES of that series for which
payment had not been subsequently made or in respect of a covenant and provision
of the Indenture which cannot be modified or amended without the consent of the
holder of each Outstanding STRYPES of such series affected.

GOVERNING LAW

  The Indenture and the STRYPES will be governed by, and construed in accordance
with, the laws of the State of New York.

LISTING

  The STRYPES have been listed on the NYSE under the symbol CML.

                         CERTAIN ARRANGEMENTS WITH CEI

  Pursuant to an agreement (the "STRYPES Agreement"), CEI is obligated to
deliver to Merrill Lynch Capital Services, Inc., a wholly-owned subsidiary of
the Company (the "ML&Co. Subsidiary"), immediately prior to the Maturity Date a
number of shares of Cox Common Stock equal to the number required by the Company
to pay and discharge all of the STRYPES. In lieu of delivering shares of Cox
Common Stock immediately prior to the Maturity Date, CEI has the right to
satisfy its obligation under the STRYPES Agreement by delivering at such time
cash in an amount equal to the value of such number of shares of Cox Common
Stock at the Maturity Price. Such right, if exercised by CEI, must be exercised
with respect to all shares of Cox Common Stock then deliverable pursuant to the
STRYPES Agreement. Under the STRYPES Agreement, the Company has agreed to pay
and discharge the STRYPES by delivering to the holders thereof on the Maturity
Date the form of consideration that the ML&Co. Subsidiary receives from CEI. CEI
also has the option, exercisable on or after a Tax Event Date, to satisfy and
discharge its obligations under the STRYPES Agreement by delivering to the
ML&Co. Subsidiary, on a date fixed by CEI for early settlement, cash and shares
of Cox Common Stock in an amount and number, respectively, equal to the amount
and number required by the Company to redeem all of the STRYPES. Under the
STRYPES Agreement, the Company has agreed to redeem all of the STRYPES in the
event that CEI exercises such option. The consideration paid by the ML&Co.
Subsidiary under the STRYPES Agreement is $188,572,500 in the aggregate, and was
paid to CEI on May 29, 1996. No other consideration is payable by the ML&Co.
Subsidiary to CEI in connection with its acquisition of the Cox Common Stock or
the performance of the STRYPES Agreement by CEI. The Company has agreed with CEI
that, without the prior consent of CEI, it will not amend the Indenture to
increase the consideration that CEI is obligated to deliver pursuant to the
STRYPES Agreement.

  Until such time, if any, as CEI shall have delivered shares of Cox Common
Stock to the ML&Co. Subsidiary pursuant to the terms of the STRYPES Agreement,
CEI will retain all ownership rights with respect to the Cox Common Stock held
by it (including, without limitation, voting rights and rights to receive any
dividends or other distributions in respect thereof).

  CEI has no obligations with respect to the STRYPES or amounts to be paid to
holders thereof, including any obligation to take the needs of the Company or
holders of the STRYPES into consideration in determining whether to deliver
shares of Cox Common Stock or cash or for any other reason. The STRYPES
Agreement between the ML&Co. Subsidiary and CEI is a commercial transaction and
does not create any rights in, or for the benefit of, any third party, including
any holder of STRYPES.

  In the event CEI does not perform under the STRYPES Agreement, the Company
will be required to otherwise acquire shares of Cox Common Stock for delivery to
holders of the STRYPES on the Maturity Date or upon
<PAGE>
 
redemption, unless, in the case of shares deliverable on the Maturity Date, it
elects to exercise its option to deliver cash with an equal value.

PROSPECTUS
- ----------
                           MERRILL LYNCH & CO., INC.
                     7 1/4% STRYPES(SM) DUE JUNE 15, 1999
            PAYABLE WITH SHARES OF COMMON STOCK OF SUNAMERICA INC.
                                 (OR IN CASH)
                             --------------------
   On June 6, 1996, Merrill Lynch & Co., Inc. (the "Company") issued 3,000,000
of its Structured Yield Product Exchangeable for Stock(SM), 7 1/4% STRYPES(SM)
Due June 15, 1999 (each, a "STRYPES"). The issue price of each STRYPES was
$56.375, which amount was equal to the last sale price of the common stock, par
value $1.00 per share (the "SunAmerica Common Stock"), of SunAmerica Inc., a
Maryland corporation ("SunAmerica"), on June 6, 1996, as reported on the New
York Stock Exchange (the "Initial Price"). The STRYPES will mature on June 15,
1999 (the "Maturity Date"). Interest on the STRYPES, at the rate of 7 1/4% of
the issue price per annum, is payable in cash quarterly in arrears on March 15,
June 15, September 15 and December 15, beginning September 15, 1996. The STRYPES
are not subject to redemption or any sinking fund prior to maturity. The STRYPES
are unsecured obligations of the Company ranking pari passu with all of its
other unsecured and unsubordinated indebtedness. See "Description of the 
STRYPES-Ranking." On the Maturity Date, unless redeemed on or prior to such
date, the Company will pay and discharge each STRYPES by delivering to the
holder thereof one share of SunAmerica Common Stock, subject to adjustment in
certain events (subject to the Company's right to deliver, with respect to all,
but not less than all, of the STRYPES then outstanding, cash in an amount equal
to the Current Market Price (as defined herein), determined as of the second
Trading Day (as defined herein) prior to the applicable Notice Date (as defined
herein), of SunAmerica Common Stock which otherwise would have been delivered).
BECAUSE THE PRICE OF THE SUNAMERICA COMMON STOCK IS SUBJECT TO MARKET
FLUCTUATIONS, THE VALUE OF THE SUNAMERICA COMMON STOCK (OR, AT THE OPTION OF THE
COMPANY, THE AMOUNT OF CASH) RECEIVED BY A HOLDER OF STRYPES AT MATURITY MAY BE
LESS THAN THE AMOUNT PAID FOR THE STRYPES UPON ISSUANCE, IN WHICH CASE AN
INVESTMENT IN THE STRYPES WILL RESULT IN LOSS.

   At any time or from time to time on or prior to the Maturity Date, the
Company may, at its option, redeem the outstanding STRYPES, in whole or in part,
at a redemption price per STRYPES initially equal to $86.568, declining by
$.00966 on each day following the Issue Date to $76.686 on April 15, 1999, and
equal to $76.106 thereafter, payable in either (i) shares of SunAmerica Common
Stock having an aggregate Current Market Price, determined as of the second
Trading Day prior to the applicable Notice Date, equal to the applicable
redemption price or (ii) at the Company's option (which may be exercised with
respect to all, but not less than all, of the STRYPES to be redeemed on any
redemption date) cash, plus in either case an amount in cash equal to accrued
and unpaid interest on the STRYPES to but excluding the redemption date. The
STRYPES are not subject to any sinking fund.

   The opportunity for capital appreciation afforded by an investment in the
STRYPES is limited because the Company may, at its option, redeem the STRYPES at
any time on or prior to the Maturity Date at the redemption prices described
above. Although not obligated to do so, the Company may be expected to redeem
the STRYPES on or prior to the Maturity Date if the market price of the
SunAmerica Common Stock exceeds the applicable redemption price, in which event
holders of STRYPES will receive less than one share of SunAmerica Common Stock
for each STRYPES (or, at the option of the Company, cash in an amount equal to
the Current Market Price of less than one share of such SunAmerica Common
Stock).

   The Notice Date applicable to the Maturity Date or a redemption date will be
at least 30 days and could be up to 60 days prior to such Maturity Date or
redemption date, as the case may be. If, as described above, the Company (i)
elects to pay the STRYPES in cash at maturity or (ii) elects to redeem the
STRYPES, in whole or in part, and to pay the redemption price by delivering
shares of SunAmerica Common Stock, the amount of cash payable on the Maturity
Date or the number of shares to be delivered on the redemption date, as the case
may be, will be determined on the basis of the Current Market Price as of the
second Trading Day prior to the applicable Notice Date. The price of the
SunAmerica Common Stock is subject to market fluctuations and, as a result, (a)
the amount of cash delivered on the Maturity Date in respect of each STRYPES may
be more or less than the market value on the Maturity Date of the SunAmerica
Common Stock which a holder would otherwise have been entitled to receive and
(b) the market value on a redemption date of shares of SunAmerica Common Stock
delivered in respect of each STRYPES may be more or less than the applicable
redemption price.

   SunAmerica Inc. is not affiliated with the Company and has no obligation with
respect to the STRYPES.

                                 RISK FACTORS
                                        
RISK OF FLUCTUATIONS IN PRICE OF SUNAMERICA COMMON STOCK; CALCULATION OF CURRENT
MARKET PRICE

   Because the price of the SunAmerica Common Stock is subject to market
fluctuations, the value of the SunAmerica Common Stock (or, pursuant to the
option of the Company exercisable at maturity, the amount of cash) received by a
holder of STRYPES upon maturity may be less than the amount paid for the STRYPES
upon issuance, in which case an investment in the STRYPES will result in a loss.
ACCORDINGLY, A HOLDER OF STRYPES ASSUMES THE RISK THAT THE MARKET VALUE OF THE
SUNAMERICA COMMON STOCK MAY DECLINE, AND THAT SUCH DECLINE COULD BE SUBSTANTIAL.
THE SUNAMERICA PROSPECTUS COVERS THE SHARES OF SUNAMERICA COMMON STOCK WHICH MAY
BE RECEIVED BY A HOLDER OF THE STRYPES ON THE MATURITY DATE OR UPON REDEMPTION.

   The Notice Date applicable to the Maturity Date or a redemption date will be
at least 30 days and could be up to 60 days prior to such Maturity Date or
redemption date, as the case may be. If the Company (i) elects to pay the
STRYPES in cash at maturity or (ii) elects to redeem the STRYPES, in whole or in
part, and to pay the redemption price by delivering shares of SunAmerica Common
Stock, the amount of cash payable on the Maturity Date or the number of shares
to be delivered on the redemption date, as the case may be, will be determined
on the basis of the Current Market Price as of the second Trading Day prior to
the applicable Notice Date. The price of the SunAmerica Common Stock is subject
to market fluctuations and, as a result, (a) the amount of cash delivered on the
Maturity Date in respect of each STRYPES may be more or less than the market
value on the Maturity Date of the SunAmerica Common Stock which a holder would
otherwise have been entitled to receive and (b) the market value on a redemption
date of shares of SunAmerica Common Stock delivered in respect of each STRYPES
may be more or less than the applicable redemption price.

   As described under "Description of the STRYPES--Certain Definitions," the
Current Market Price used to determine the amount of cash which may, at the
option of the Company, be paid at maturity or the number of shares of SunAmerica
Common Stock which may, at the option of the Company, be delivered upon any
redemption of the STRYPES will generally be equal to the average of the daily
Closing Prices (as defined) of the SunAmerica Common Stock for the five
consecutive Trading Days ending on and including the date of determination.
However, if the Closing Price on the Trading Day next following such five-day
period (the "Next-Day Closing Price") is less than 95% of such five-day average
Closing Price, then the Current Market Price on such date of determination will
be the Next-Day Closing Price. Because the price of the SunAmerica Common Stock
is subject to market fluctuations, it is possible that the Next-Day Closing
Price could be significantly less than such five-day average.

Limitation on Opportunity for Capital Appreciation

   The opportunity for capital appreciation afforded by an investment in the
STRYPES is less than the opportunity for capital appreciation afforded by a
direct investment in the SunAmerica Common Stock. The opportunity for capital
appreciation afforded by an investment in the STRYPES is limited because the
Company may, at its option, redeem the STRYPES at any time on or prior to the
Maturity Date at the redemption prices described herein. Although not obligated
to do so, the Company may be expected to redeem the STRYPES on or prior to the
Maturity Date if the market price of the SunAmerica Common Stock exceeds the
applicable redemption price, in which event holders of STRYPES will receive less
than one share of SunAmerica Common Stock for each STRYPES (or, at the option of
the Company, cash in an amount equal to the Current Market Price of less than
one share of such SunAmerica Common Stock). See "Description of the STRYPES--
Optional Redemption." If the Company elects to redeem the STRYPES, in whole or
in part, the capital appreciation, exclusive of accrued interest, realized on an
investment in the STRYPES will, for any owner of STRYPES called for redemption,
be limited to the excess, if any, of (i) the value of the SunAmerica Common
Stock or the amount of cash, as the case may be, received in payment of such
redemption price (such redemption price being initially $86.568 and declining
thereafter to $76.106), over (ii) the price paid by such owner for such STRYPES
(the initial price being the price to public for each STRYPES shown on the cover
page of this Prospectus and the price thereafter being subject to market

                                       3
<PAGE>
 
fluctuations).

FACTORS AFFECTING TRADING PRICES

   The trading prices of the STRYPES in the secondary market will be directly
affected by the trading prices of the SunAmerica Common Stock in the secondary
market. It is impossible to predict whether the price of SunAmerica Common Stock
will rise or fall. Trading prices of SunAmerica Common Stock will be influenced
by SunAmerica's operating results and prospects, by complex and interrelated
political, economic, financial and other factors and market conditions that can
affect the capital markets generally, the market segment of which SunAmerica is
a part, the NYSE (on which the SunAmerica Common Stock is traded), including the
level of, and fluctuations  in, the trading prices of stocks generally and sales
of substantial amounts of SunAmerica Common Stock in the market subsequent to
the offering of the STRYPES or the perception that such sales could occur, and
by other events that are difficult to predict and beyond the Company's control.

IMPACT OF STRYPES ON THE MARKET FOR SUNAMERICA COMMON STOCK

   It is not possible to predict accurately how the STRYPES will trade in the
secondary market or whether such market will be liquid. Any market that develops
for the STRYPES is likely to influence and be influenced by the market for
SunAmerica Common Stock. For example, the price of SunAmerica Common Stock could
be depressed by investors' anticipation of the potential distribution into the
market of substantial additional amounts of SunAmerica Common Stock on the
Maturity Date or upon redemption of the STRYPES, by possible sales of SunAmerica
Common Stock by investors who view the STRYPES as a more attractive means of
equity participation in SunAmerica and by hedging or arbitrage trading activity
that may develop involving the STRYPES and the SunAmerica Common Stock. In
addition Mr. Eli Broad (the "Selling Stockholder"is not precluded from selling
SunAmerica Common Stock.  Any such sales could have an adverse effect on the
market price of SunAmerica Common Stock and/or the STRYPES.

POSSIBLE ILLIQUIDITY OF THE SECONDARY MARKET

   It is not possible to predict how the STRYPES will trade in the secondary
market or whether such market will be liquid or illiquid. The STRYPES are novel
securities and there is currently no secondary market for the STRYPES.  The
STRYPES have been listed on the NYSE under the symbol "SAI".  However there can
be no assurance that an active trading market for the STRYPES will develop, that
such listing will provide the holders of the STRYPES with liquidity of
investment, or that the STRYPES will not later be delisted or that trading of
the STRYPES on the NYSE will not be suspended. In the event of a delisting or
suspension of trading on the NYSE, the Company will apply for listing of the
STRYPES on another national securities exchange or for quotation on another
trading market.  If the STRYPES are not listed or traded on any securities
exchange or trading market, or if trading of the STRYPES is suspended, pricing
information for the STRYPES may be more difficult to obtain and the liquidity of
the STRYPES may be adversely affected.

NO STOCKHOLDER RIGHTS

   Holders of the STRYPES will not be entitled to any rights with respect to the
SunAmerica Common Stock (including without limitation voting rights and rights
to receive any dividends or other distributions in respect thereof) unless and
until such time, if any, as the Company shall have delivered shares of
SunAmerica Common Stock for STRYPES on the Maturity Date or upon redemption and
unless the applicable record date, if any, for the exercise of such rights
occurs after such date.  For example, in the event that an amendment is proposed
to the certificate of incorporation of SunAmerica and the record date for
determining the stockholders of record entitled to vote on such amendment occurs
prior to such delivery, holders of the STRYPES will not be entitled to vote on
such amendment.

NO AFFILIATION BETWEEN THE COMPANY AND THE SELLING STOCKHOLDER

   The Company has no affiliation with the Selling Stockholder, and the Selling
Stockholder has no obligation with respect to the STRYPES or amounts to be paid
to the holders thereof, including any obligation to take the needs of the
Company or of the holders of STRYPES into consideration in determining whether
or when to cause redemption of the STRYPES or whether to deliver shares or cash
at maturity or upon redemption, or for any other reason.

NO AFFILIATION BETWEEN THE COMPANY AND SUNAMERICA

   The Company has no affiliation with SunAmerica, and SunAmerica has no
obligations with respect to the STRYPES or amounts to be paid to holders
thereof, including any obligation to take the needs of the Company or of holders
of the STRYPES into consideration for any reason. SunAmerica will not receive
any of the proceeds of the offering of the STRYPES made hereby and is not
responsible for, and has not participated in, the determination or calculation
of the amount receivable by holders of the STRYPES on the Maturity Date or upon
redemption. SunAmerica is not involved with the administration or trading of the
STRYPES and has no obligations with respect to the amount receivable by holders
of the STRYPES on the Maturity Date or upon redemption.

DILUTION OF SUNAMERICA COMMON STOCK

   The number of shares of SunAmerica Common Stock (or, pursuant to the option
of the Company, the amount of cash) that holders of the STRYPES are entitled to
receive on the Maturity Date or upon redemption is subject to adjustment for
certain events arising from, among other things, a merger or consolidation in
which SunAmerica is not the surviving or resulting corporation, or a sale or
transfer of all or substantially all of the assets of SunAmerica on the
liquidation, dissolution, winding up or bankruptcy of SunAmerica, as well as
stock splits and combinations, stock dividends and certain other actions of
SunAmerica that modify its capital structure. See "Description of the STRYPES--
Dilution Adjustments."  Such number of shares of SunAmerica Common Stock (or,
pursuant to the option of the Company, the amount of cash) to be received by
such holders on the Maturity Date or upon redemption will not be adjusted for
other events, such as offerings of SunAmerica Common Stock for cash or in
connection with acquisitions. SunAmerica is not restricted from issuing
additional shares of SunAmerica Common Stock during the term of the STRYPES and
has no obligation to consider the interests of the holders of the STRYPES for
any reason. Additional issuances may materially and adversely affect the market
price of the SunAmerica Common Stock and of the STRYPES.

TAX MATTERS

   Because of an absence of authority as to the proper characterization of the
STRYPES, their ultimate tax treatment is uncertain. Accordingly, no assurances
can be given that any particular characterization and treatment of the STRYPES
will be accepted by the Internal Revenue Service ("IRS") or upheld by a court.
However, it is the opinion of Brown & Wood LLP, counsel to the Company, that the
characterization and tax treatment of the STRYPES described herein, while not
the only reasonable characterization and tax treatment, is based on reasonable
interpretations of law currently in effect and, even if successfully challenged
by the IRS, will not result in the imposition of penalties. The Indenture (as
defined below) will require that any holder subject to United States Federal
income tax include currently in income, for United States Federal income tax
purposes, payments denominated as interest that are made with respect to a
STRYPES in accordance with such holder's regular method of tax accounting. The
Indenture also requires the Company and holders to treat each STRYPES for tax
purposes as a unit (a "Unit") consisting of (i) a debt instrument (the "Debt
Instrument") with a fixed principal amount unconditionally payable on the
Maturity Date equal to the Issue Price of the STRYPES and bearing interest at
the stated interest rate on the STRYPES and (ii) a forward purchase contract
(the "Forward Contract") pursuant to which the holder agrees to use the
principal payment due on the Debt Instrument (or, in the event of redemption on
or prior to the Maturity Date, the redemption price) to purchase on the Maturity
Date or upon redemption on or prior to the Maturity Date the SunAmerica Common
Stock which the Company is obligated under the STRYPES

                                       5
<PAGE>
 
to deliver at that time (subject to the Company's right to deliver cash in lieu
of the SunAmerica Common Stock). The Indenture also requires that upon the
acquisition of a STRYPES and upon a holder's sale or other disposition of a
STRYPES prior to the Maturity Date or redemption of the STRYPES, the amount paid
or realized by the holder be allocated by the holder between the Debt Instrument
and the Forward Contract based upon their relative fair market values (as
determined on the date of acquisition or disposition). For these purposes, with
respect to acquisitions of STRYPES in connection with the original issuance
thereof, the Company and each holder agrees, pursuant to the terms of the
Indenture, to assign $57.277 (i.e., 101.6%) of the initial purchase price of a
STRYPES (i.e., the Issue Price of a STRYPES) to the Debt Instrument component
and to assign $.902 (i.e., 1.6%) of the initial purchase price of a STRYPES to
the Forward Contract component. As previously mentioned, the appropriate
character and timing of income, gain or loss to be recognized on a STRYPES is
uncertain and investors should consult their own tax advisers concerning the
application of the United States Federal income tax laws to their particular
situations as well as any consequences of the purchase, ownership and
disposition of the STRYPES arising under the laws of any other taxing
jurisdiction.

HOLDING COMPANY STRUCTURE

   Since the Company is a holding company, the right of the Company, and hence
the right of creditors of the Company (including the holders of the STRYPES), to
participate in any distribution of the assets of any subsidiary upon its
liquidation or reorganization or otherwise is necessarily subject to the prior
claims of creditors of the subsidiary, except to the extent that claims of the
Company itself as a creditor of the subsidiary may be recognized. In addition,
dividends, loans and advances from certain subsidiaries, including MLPF&S, to
the Company are restricted by net capital requirements under the Exchange Act,
and under the rules of certain securities exchanges and other regulatory bodies.

                           DESCRIPTION OF THE STRYPES

  The STRYPES are a series of Senior Debt Securities issued under an indenture
dated as of April 1, 1983 and restated as of April 1, 1987, as amended and
supplemented as of July 1, 1995 (the indenture dated as of April 1, 1983 and
restated as of April 1, 1987, as amended and supplemented from time to time, the
"Indenture") between the Company and The Chase Manhattan Bank, formerly known as
Chemical Bank (successor by merger to Manufacturers Hanover Trust Company), as
trustee (the "Trustee"). The following summary of certain provisions of the
Indenture does not purport to be complete and is qualified in its entirety by
reference to the Indenture, a copy of which is filed as an exhibit to the
Registration Statement of which this Prospectus is a part. All capitalized terms
not otherwise defined herein have the meanings specified in the Indenture.
Whenever defined terms of the Indenture are referred to herein, such defined
terms are incorporated by reference herein.

                                       7
<PAGE>
 
GENERAL


  Each STRYPES, which was issued at the Issue Price of $56.375, bears interest
at the rate of 7/1//4% of the Issue Price per annum (or $4.0872 per annum) from
June 12, 1996, or from the most recent Interest Payment Date to which interest
has been paid or provided for, until the Maturity Date or such earlier date on
which such STRYPES is redeemed or the Issue Price of such STRYPES is repaid
pursuant to the terms thereof. Interest on the STRYPES will be payable in cash
quarterly in arrears on March 15, June 15, September 15 and December 15,
beginning September 15, 1996, and on the Maturity Date (each, an "Interest
Payment Date"), to the persons in whose names the STRYPES are registered at the
close of business on the last day (whether or not a Business Day) of the
calendar month immediately preceding such Interest Payment Date. Interest on the
STRYPES will be computed on the basis of a 360-day year of twelve 30-day months.
If an Interest Payment Date, Maturity Date or redemption date falls on a day
that is not a Business Day, the payments to be made (including any shares of
SunAmerica Common Stock to be delivered) on such date will be made on the next
succeeding Business Day with the same force and effect as if made on such
Interest Payment Date, Maturity Date or redemption date, and no additional
interest will accrue as a result of such delayed payment.

PAYMENTS AT MATURITY

  The STRYPES will mature on June 15, 1999. On the Maturity Date, unless
redeemed on or prior to such date, the Company will pay and discharge each
STRYPES by delivering to the holder thereof a number of shares of SunAmerica
Common Stock equal to the Common Equivalent Rate (as described below) in effect
on the Maturity Date (subject to the Company's right to deliver, with respect to
all, but not less than all, of the STRYPES then outstanding, cash in an amount
equal to the Current Market Price, determined as of the second Trading Day prior
to the applicable Notice Date, of the SunAmerica Common Stock which otherwise
would have been delivered). The Common Equivalent Rate will initially be one
share of Common Stock per STRYPES. The Common Equivalent Rate is subject to
adjustment as described below under "--Dilution Adjustments." Because the price
of the SunAmerica Common Stock is subject to market fluctuations, the value of
the SunAmerica Common Stock (or, at the option of the Company, the amount of
cash) received by a holder of STRYPES on the Maturity Date may be less than the
amount paid for the STRYPES upon issuance, in which case an investment in the
STRYPES will result in a loss.  In addition, because of such market fluctuations
and because the Current Market Price of the SunAmerica Common Stock will be
determined as of the second Trading Date prior to the applicable Notice Date
(which will be at least 30 and could be up to 60 days prior to the Maturity
Date), it is likely that, if the Company elects to pay the STRYPES in cash on
the Maturity Date, the amount of cash payable per STRYPES will differ from the
market value on the Maturity Date of the shares of SunAmerica Common Stock which
a holder would otherwise have received. See "Risk Factors--Risk of Fluctuations
in Price of SunAmerica Common Stock; Calculation of Current Market Price."

  In the Indenture, the Company will agree to deliver on the Maturity Date the
form of consideration that the ML&Co. Subsidiary receives from the Selling
Stockholder. The Company will be required to mail a notice, at least 30 but not
more than 60 days prior to the Maturity Date, to each holder of STRYPES at its
registered address, which notice shall state whether the STRYPES will be paid
and discharged with shares of SunAmerica Common Stock or in cash and, if payable
in cash, specifying the amount of cash payable for each STRYPES and the Current
Market Price used to calculate such amount. If the Company elects to deliver
shares of SunAmerica Common Stock, holders of the STRYPES will be responsible
for the payment of any and all brokerage costs upon the subsequent sale of such
stock.

OPTIONAL REDEMPTION

  At any time or from time to time on or prior to the Maturity Date, the Company
may, at its option, redeem the outstanding STRYPES, in whole or in part, at a
redemption price per STRYPES initially equal to $86.568, declining

                                       8
<PAGE>
 
by $.00966 on each day following the Issue Date (computed on the basis of a 360-
day year of twelve 30-day months) to $76.686 on April 15, 1999, and equal to
$76.106 thereafter, payable in either (i) a number of shares of SunAmerica
Common Stock equal to the redemption price on the applicable redemption date
divided by the Current Market Price of the SunAmerica Common Stock determined as
of the second Trading Day preceding the applicable Notice Date or (ii) at the
Company's option (which may be exercised with respect to all, but not less than
all, of the STRYPES to be redeemed on any redemption date) cash, plus in either
case an amount in cash equal to accrued and unpaid interest on the STRYPES to
but excluding the redemption date; provided that installments of interest which
are due and payable on or prior to the redemption date shall be payable to the
holders of STRYPES registered as such at the close of business on the relevant
record dates. On and after the redemption date, interest will cease to accrue on
the STRYPES called for redemption, unless the Company defaults in the payment of
the redemption price therefor. If the Company elects to deliver shares of
SunAmerica Common Stock, holders of the STRYPES will be responsible for the
payment of any and all brokerage costs upon the subsequent sale of such stock.

  Notice of redemption shall be mailed at least 30 days but not more than 60
days before the redemption date to each holder of STRYPES to be redeemed at its
registered address. Such notice shall specify whether the Company will pay the
redemption price by delivery of SunAmerica Common Stock or in cash and, if
payable in SunAmerica Common Stock, will also specify the number of shares of
SunAmerica Common Stock to be delivered for each STRYPES and the Current Market
Price used to calculate such number of shares. If only a portion of the STRYPES
held by any registered holder are to be redeemed, the notice of redemption shall
specify the number of STRYPES to be redeemed from such holder and, upon
redemption, a new STRYPES certificate evidencing the unredeemed STRYPES will be
issued in the name of the holder upon surrender for cancellation of the original
certificate.

  In the event that less than all of the STRYPES are to be redeemed at any time,
selection of STRYPES for redemption will be made by the Trustee by such method
as the Trustee shall deem fair and appropriate (subject to compliance with the
requirements of the principal national securities exchange on which the STRYPES
may be listed); provided, however, that the STRYPES shall not be redeemed except
in units of one or more whole STRYPES.

  The opportunity for capital appreciation afforded by an investment in the
STRYPES is limited because the Company may, at its option, redeem the STRYPES at
any time on or prior to the Maturity Date at the redemption prices described
above. Although not obligated to do so, the Company may be expected to redeem
the STRYPES on or prior to the Maturity Date if the market price of the
SunAmerica Common Stock exceeds the applicable redemption price, in which event
holders of STRYPES will receive less than one share of SunAmerica Common Stock
for each STRYPES (or, at the option of the Company, cash in an amount equal to
the Current Market Price of less than one share of such SunAmerica Common
Stock). See "Risk Factors--Limitation on Opportunity for Capital Appreciation."

  If the Company exercises its option to redeem the STRYPES, in whole or in
part, the Notice Date for such redemption will be at least 30 days and could be
up to 60 days prior to the redemption date. If, as described above, the Company
elects to pay the redemption price by delivering shares of SunAmerica Common
Stock, the number of shares to be so delivered will be determined on the basis
of the Current Market Price as of the second Trading Date prior to the Notice
Date. The price of the SunAmerica Common Stock is subject to market fluctuations
and, as a result, the market value on such redemption date of the shares of
SunAmerica Common Stock delivered in respect of each STRYPES may be more or less
than the applicable redemption price. See "Risk Factors--Risk of Fluctuations in
Price of SunAmerica Common Stock; Calculation of Current Market Price."

CERTAIN DEFINITIONS

  The "Closing Price" of any security on any day shall mean the closing sales
price regular way on such day or, in case no such sale takes place on such day,
the average of the reported closing bid and asked prices regular way on such
day, in each case on the NYSE, or, if such security is not listed or admitted to
trading on the NYSE, on the principal national securities exchange on which such
security is listed or admitted to trading, or, if not listed or

                                       9
<PAGE>
 
admitted to trading on any national securities exchange, the average of the
closing bid and asked prices of such security on the over-the-counter market on
the day in question as reported by the National Quotation Bureau Incorporated,
or a similarly generally accepted reporting service, or if not so available in
such manner, as furnished by any NYSE member firm selected from time to time by
the Board of Directors of the Company for that purpose.

  The "Current Market Price" per share of the SunAmerica Common Stock on any
date of determination means the average of the daily Closing Prices for the five
consecutive Trading Days ending on and including such date of determination
(appropriately adjusted to take into account the occurrence during such five-day
period of any event that results in an adjustment of the Common Equivalent
Rate); provided, however, that if the Closing Price of the SunAmerica Common
Stock on the Trading Day next following such five-day period (the "Next-Day
Closing Price") is less than 95% of such five-day average, then the Current
Market Price per share of SunAmerica Common Stock on such date of determination
will be the Next-Day Closing Price; and provided, further, that, for the
purposes of calculating the Current Market Price in connection with the Maturity
Date or any redemption of STRYPES or any determination of an amount in cash
payable in lieu of a fractional share of SunAmerica Common Stock, if any
adjustment of the Common Equivalent Rate becomes effective as of any date during
the period beginning on the first day of such five-day period and ending on the
Maturity Date or the relevant redemption date, as the case may be, then the
Current Market Price as determined pursuant to the foregoing will be
appropriately adjusted to reflect such adjustment. Because the price of
SunAmerica Common Stock is subject to market fluctuations, it is possible that
the Next-Day Closing Price could be significantly less than such five-day
average. See "Risk Factors--Risk of Fluctuations in Price of SunAmerica Common
Stock; Calculation of Current Market Price."

  A "Notice Date" with respect to any notice given by the Company in connection
with the Maturity Date or any redemption of STRYPES means the commencement of
the mailing of such notice to the holders of STRYPES in accordance with "--
Payments at Maturity" or "--Optional Redemption," as the case may be, above.

  A "Trading Day" is defined as a day on which the security, the Closing Price
of which is being determined, (A) is not suspended from trading on any national
or regional securities exchange or association or over-the-counter market at the
close of business and (B) has traded at least once on the national or regional
securities exchange or association or over-the-counter market that is the
primary market for the trading of such security; provided that, if the Closing
Price of such security is to be determined by a NYSE member firm, then the term
Trading Day shall mean, for purposes of determining such Closing Price, a day on
which the NYSE is open for trading.

DILUTION ADJUSTMENTS

  The Common Equivalent Rate will initially be one share of SunAmerica Common
Stock for each STRYPES. The Common Equivalent Rate is subject to adjustment if
SunAmerica shall: (i) pay a dividend or make a distribution with respect to
SunAmerica Common Stock in shares of SunAmerica Common Stock; (ii) subdivide or
split the outstanding shares of SunAmerica Common Stock into a greater number of
shares; (iii) combine the outstanding shares of SunAmerica Common Stock into a
smaller number of shares; (iv) issue by reclassification of shares of SunAmerica
Common Stock any shares of common stock of SunAmerica; (v) issue certain rights
or warrants to all holders of SunAmerica Common Stock; or (vi) pay a dividend or
make a distribution to all holders of SunAmerica Common Stock of evidences of
its indebtedness or other assets (including shares of capital stock of
SunAmerica but excluding any cash dividends and any stock dividends or
distributions referred to in clause (i) above).

  All adjustments to the Common Equivalent Rate will be calculated to the
nearest 1/100th of a share of SunAmerica Common Stock (or if there is not a
nearest 1/100th of a share to the next lower 1/100th of a share). No adjustment
in the Common Equivalent Rate shall be required unless such adjustment would
require an increase or decrease of at least one percent therein; provided,
however, that any adjustments which by reason of the foregoing are not required
to be made shall be carried forward and taken into account in any subsequent
adjustment. Each such adjustment to the Common Equivalent Rate shall be made
successively.

  In the event of (A) any consolidation or merger of SunAmerica, or any
surviving entity or subsequent surviving

                                       10
<PAGE>
 
entity of SunAmerica (a "SunAmerica Successor"), with or into another entity
(other than a merger or consolidation in which SunAmerica is the continuing
corporation and in which the SunAmerica Common Stock outstanding immediately
prior to the merger or consolidation is not exchanged for cash, securities or
other property of SunAmerica or another corporation), (B) any sale, transfer,
lease or conveyance to another corporation of the property of SunAmerica or any
SunAmerica Successor as an entirety or substantially as an entirety, (C) any
statutory exchange of securities of SunAmerica or any SunAmerica Successor with
another corporation (other than in connection with a merger or acquisition) or
(D) any liquidation, dissolution, winding up or bankruptcy of SunAmerica or any
SunAmerica Successor (any such event described in clause (A), (B), (C) or (D), a
"Reorganization Event"), the Common Equivalent Rate will be adjusted to provide
that each holder of STRYPES will receive on the Maturity Date or any redemption
date for each STRYPES cash in an amount equal to the Transaction Value.
"Transaction Value" means (i) for any cash received in any such Reorganization
Event, the amount of cash received per share of SunAmerica Common Stock, (ii)
for any property other than cash or securities received in any such
Reorganization Event, an amount equal to the market value on the Maturity Date
or any redemption date of such property received per share of SunAmerica Common
Stock as determined by a nationally recognized independent investment banking
firm retained for this purpose by the Company and (iii) for any securities
received in any such Reorganization Event, an amount equal to the average
Closing Price per unit of such securities on the five Trading Days immediately
prior to the second Trading Day preceding the Maturity Date or any redemption
date multiplied by the number of such securities received for each share of
SunAmerica Common Stock. Notwithstanding the foregoing, in the event that
property or securities, or a combination of cash, on the one hand, and property
or securities, on the other, are received in such Reorganization Event, the
Company may, at its option, in lieu of delivering cash as described above,
deliver the amount of cash, securities and other property received per share of
SunAmerica Common Stock in such Reorganization Event determined in accordance
with clause (i), (ii) or (iii) above, as applicable. If the Company elects to
deliver securities or other property, holders of the STRYPES will be responsible
for the payment of any and all brokerage and other transaction costs upon any
subsequent sale of such securities or other property. The kind and amount of
securities with which the STRYPES shall be paid and discharged after
consummation of such transaction shall be subject to adjustment as described
above following the date of consummation of such transaction.

  No adjustments will be made for certain other events, such as offerings of
SunAmerica Common Stock by SunAmerica for cash or in connection with
acquisitions. Likewise, no adjustments will be made for any sales of SunAmerica
Common Stock by the Selling Stockholder.

  The Company is required, within ten Business Days following the occurrence of
an event that requires an adjustment to the Common Equivalent Rate (or if the
Company is not aware of such occurrence, as soon as practicable after becoming
so aware), to provide written notice to the Trustee and to the holders of the
STRYPES of the occurrence of such event and a statement in reasonable detail
setting forth the adjusted Common Equivalent Rate and the method by which the
adjustment to the Common Equivalent Rate was determined.

CERTAIN PROCEDURES IN CONNECTION WITH MATURITY AND REDEMPTION

  Each holder of STRYPES on the Maturity Date, and each holder of STRYPES called
for redemption on any redemption date, must surrender the certificates
evidencing such STRYPES at the office or agency of the Company maintained for
such purpose in order to receive the consideration payable on such date. If, on
the Maturity Date or any redemption date, the Company shall have deposited with
the Trustee or other agent under the Indenture the consideration payable on such
date in respect of all of the STRYPES then outstanding (in the case of the
Maturity Date) or the STRYPES called for redemption (in the case of any
redemption date), then, on the Maturity Date or redemption date, as the case may
be, all of the outstanding STRYPES or the STRYPES called for redemption, as the
case may be, shall cease to bear interest and all rights of the holders thereof
shall terminate (except for the right to receive the consideration payable in
respect of such STRYPES on such date), notwithstanding that the certificates
evidencing any of the STRYPES which are payable or subject to redemption on such
date shall not have been surrendered to the Company.

                                       11

FRACTIONAL SHARES

  No fractional shares of SunAmerica Common Stock will be delivered if the
Company pays and discharges the STRYPES by delivering shares of SunAmerica
Common Stock on the Maturity Date or any redemption date. In lieu of any
fractional share otherwise deliverable in respect of all STRYPES of any holder
on the Maturity Date or any redemption date, such holder shall be entitled to
receive an amount in cash equal to the value of such fractional share at the
Current Market Price of the SunAmerica Common Stock determined as of the second
Trading Day immediately preceding the relevant Notice Date.

NO SINKING FUND

  The STRYPES do not contain sinking fund or other mandatory redemption
provisions. The STRYPES are not subject to payment prior to the Maturity Date at
the option of the holder.

RANKING

  The STRYPES will be unsecured obligations and will rank pari passu with all
other unsecured and unsubordinated indebtedness of the Company.

  There are no contractual restrictions on the ability of the Company or its
subsidiaries to incur additional secured or unsecured debt. However, borrowings
by certain subsidiaries, including MLPF&S, are restricted by net capital
requirements under the Exchange Act and under rules of certain exchanges and
other regulatory bodies.

SECURITIES DEPOSITORY

  Upon issuance, each series of STRYPES will be represented by one or more fully
registered global securities (the "Global Notes"). Each such Global Note will be
deposited with, or on behalf of, The Depository Trust Company, as Securities
Depository (the "Securities Depository"), and registered in the name of the
Securities Depository or a nominee thereof. Unless and until it is exchanged in
whole or in part for STRYPES in definitive form under the limited circumstances
described below, no Global Note may be transferred except as a whole by the
Securities Depository to a nominee of such Securities Depository or by a nominee
of such Securities Depository to such Securities Depository or another nominee
of such Securities Depository or by such Securities Depository or any such
nominee to a successor of such Securities Depository or a nominee of such
successor.

  The Securities Depository has advised the Company as follows: The Securities
Depository is a limited-purpose trust company organized under the Banking Law of
the State of New York, a member of the Federal Reserve System, a "clearing
corporation" within the meaning of the New York Uniform Commercial Code, and a
"clearing agency" registered pursuant to the provisions of Section 17A of the
Exchange Act. The Securities Depository was created to hold securities of its
participants ("Participants") and to facilitate the clearance and settlement of
securities transactions among its Participants in such securities through
electronic book-entry changes in accounts of the Participants, thereby
eliminating the need for physical movement of securities certificates. The
Securities Depository's Participants include securities brokers and dealers
(including MLPF&S), banks, trust companies, clearing corporations, and certain
other organizations.

  The Securities Depository is owned by a number of Participants and by the New
York Stock Exchange, Inc., the American Stock Exchange, Inc. and the National
Association of Securities Dealers, Inc. Access to the Securities Depository's
book-entry system is also available to others, such as banks, brokers, dealers
and trust companies that clear through or maintain a custodial relationship with
a Participant, either directly or indirectly ("Indirect Participants").

  Purchases of STRYPES must be made by or through Participants, which will
receive a credit on the records

                                       12
<PAGE>
 
of the Securities Depository.  The ownership interest of each actual purchaser
of each STRYPES ("Beneficial Owner") is in turn to be recorded on the
Participants' or Indirect Participants' records. Beneficial Owners will not
receive written confirmations from the Securities Depository of their purchase,
but Beneficial Owners are expected to receive written confirmation providing
details of the transaction, as well as periodic statements of their holdings,
from the Participant or Indirect Participant through which the Beneficial Owner
entered into the transaction. Ownership of beneficial interest in such Global
Note will be shown on, and the transfer of such ownership interests will be
effected only through, records maintained by the Securities Depository (with
respect to interests of Participants) and on the records of Participants (with
respect to interests of persons held through Participants). The laws of some
states may require that certain purchasers of securities take physical delivery
of such securities in definitive form.  Such limits and such laws may impair the
ability to own, transfer or pledge beneficial interests in Global Notes.

  So long as the Securities Depository, or its nominee, is the registered owner
of a Global Note, the Securities Depository or its nominee, as the case may be,
will be considered the sole owner or holder of the STRYPES represented by such
Global Note for all purposes under the Indenture.  Except as provided below,
Beneficial Owners in a Global Note will not be entitled to have the STRYPES
represented by such Global Notes registered in their names, will not receive or
be entitled to receive physical delivery of the STRYPES in definitive form and
will not be considered the owners or holders thereof under the Indenture.
Accordingly, each Person owning a beneficial interest in a Global Note must rely
on the procedures of the Securities Depository and, if such Person is not a
Participant, on the procedures of the Participant through which such Person owns
its interest, to exercise any rights of a holder under the Indenture.  The
Company understands that under existing industry practices, in the event that
the Company requests any action of holders or that an owner of a beneficial
interest in such a Global Note desires to give or take any action which a holder
is entitled to give or take under the Indenture, the Securities Depository would
authorize the Participants holding the relevant beneficial interests to give or
take such action, and such Participants would authorize Beneficial Owners owning
through such Participants to give or take such action or would otherwise act
upon the instructions of Beneficial Owners.  Conveyance of notices and other
communications by the Securities Depository to Participants, by Participants to
Indirect Participants, and by Participants and Indirect Participants to
Beneficial Owners will be governed by arrangements among them, subject to any
statutory or regulatory requirements as may be in effect from time to time.

  Payment of any amount with respect to STRYPES registered in the name of the
Securities Depository or its nominee will be made to the Securities Depository
or its nominee, as the case may be, as the holder of the Global Notes
representing such STRYPES. None of the Company, the Trustee or any other agent
of the Company or agent of the Trustee will have any responsibility or liability
for any aspect of the records relating to or payments made on account of
beneficial ownership interests or for supervising or reviewing any records
relating to such beneficial ownership interests.  The Company expects that the
Securities Depository, upon receipt of any payment in respect of a Global Note,
will credit the accounts of the Participants with payment in amounts
proportionate to their respective holdings of beneficial interest in such Global
Note as shown on the records of the Securities Depository. The Company also
expects that payments by Participants to Beneficial Owners will be governed by
standing customer instructions and customary practices, as is now the case with
securities held for the accounts of customers in bearer form or registered in
"street name," and will be the responsibility of such Participants.

  If, with respect to a series of STRYPES, (x) the Securities Depository is at
any time unwilling or unable to continue as Securities Depository and a
successor depository is not appointed by the Company within 60 days, (y) the
Company executes and delivers to the Trustee a Company Order to the effect that
the Global Notes shall be exchangeable or (z) an Event of Default has occurred
and is continuing with respect to any STRYPES of that series, the Company will
issue STRYPES in definitive form in exchange for all of the Global Notes
representing the STRYPES of that series.  Such definitive STRYPES shall be
registered in such name or names as the Securities Depository shall instruct the
Trustee.  It is expected that such instructions may be based upon directions
received by the Securities Depository from Participants with respect to
ownership of beneficial interests in such Global Notes.

MERGER AND CONSOLIDATION

  The Company may consolidate or merge with or into any other corporation, and
the Company may sell, lease or convey all or substantially all of its assets to
any corporation, provided that (i) the corporation (if other than the Company)
formed by or resulting from any such consolidation or merger or which shall have
received such assets shall be a corporation organized and existing under the
laws of the United States of America or a state thereof and shall assume the due
and punctual delivery or payment of the Underlying Securities (or cash with an
equal value) in respect of, any interest and Additional Amounts on, and any
other amounts payable with respect to, the STRYPES of each series and the due
and punctual performance and observance of all of the covenants and conditions
of the Indenture to be performed or observed by the Company, and (ii) the
Company or such successor corporation, as the case may be, shall not immediately
thereafter be in default under the Indenture.

LIMITATIONS UPON LIENS

  The Indenture provides that the Company may not, and may not permit any
Subsidiary (defined in the Indenture as any corporation of which at the time of
determination the Company and/or one or more Subsidiaries owns or controls
directly or indirectly 50% of the shares of Voting Stock of such corporation)
to, create, assume, incur or permit to exist any indebtedness for borrowed money
secured by a pledge, lien or other encumbrance (except for certain liens
specifically permitted by the Indenture) on the Voting Stock owned directly or
indirectly by the Company of any Subsidiary (other than a Subsidiary which, at
the time of incurrence of such secured indebtedness, has a net worth of less
than $3,000,000) without making effective provision whereby the Outstanding
STRYPES will be secured equally and ratably with such secured indebtedness.

LIMITATIONS ON DISPOSITION OF VOTING STOCK OF, AND MERGER AND SALE OF ASSETS BY,
MLPF&S

  The Indenture provides that the Company may not sell, transfer or otherwise
dispose of any Voting Stock of MLPF&S or permit MLPF&S to issue, sell or
otherwise dispose of any of its Voting Stock, unless, after giving effect to any
such transaction, MLPF&S remains a Controlled Subsidiary (defined in the
Indenture to mean a corporation more than 80% of the outstanding shares of
Voting Stock of which are owned directly or indirectly by the Company).  In
addition, the Indenture provides that the Company may not permit MLPF&S to (i)
merge or consolidate, unless the surviving company is a Controlled Subsidiary,
or (ii) convey or transfer its properties and assets substantially as an
entirety, except to one or more Controlled Subsidiaries.

EVENTS OF DEFAULT

  Each of the following will constitute an Event of Default under the Indenture
with respect to each series of STRYPES: (a) failure to pay and discharge the
STRYPES of that series with the Underlying Securities or, if the Company so
elects, to pay an equivalent amount in cash in lieu thereof when due; (b)
failure to pay the Redemption Price or any redemption premium with respect to
any STRYPES of that series when due; (c) failure to deposit any sinking fund
payment, when and as due by the terms of any STRYPES of that series; (d) failure
to pay any interest on or any Additional Amounts in respect of any STRYPES of
that series when due, continued for 30 days; (e) failure to perform any other
covenant of the Company contained in the Indenture for the benefit of that
series or in the STRYPES of that series, continued for 60 days after written
notice has been given to the Company by the Trustee, or to the Company and the
Trustee by the holders of at least 10% of the aggregate issue price of the
Outstanding STRYPES of that series, as provided in the Indenture; (f) certain
events in bankruptcy, insolvency or reorganization of the Company; and (g) any
other Event of Default provided with respect to STRYPES of that series.

  If an Event of Default (other than an Event of Default described in clause (f)
of the immediately preceding paragraph) with respect to the STRYPES of any
series shall occur and be continuing, either the Trustee or the holders of at
least 25% of the aggregate issue price of the Outstanding STRYPES of that series
by notice as provided in the Indenture may declare an amount equal to the
aggregate issue price of all the STRYPES of that series and the interest accrued
thereon and Additional Amounts payable in respect thereof, if any, to be
immediately due and payable in

                                       14
<PAGE>
 
cash.  If an Event of Default described in said clause (f) shall occur, an
amount equal to the aggregate issue price of all the STRYPES of that series and
the interest accrued thereon and Additional Amounts payable in respect thereof,
if any, will become immediately due and payable in cash without any declaration
or other action on the part of the Trustee or any holder.  After such
acceleration, but before a judgment or decree based on acceleration, the holders
of a majority of the aggregate issue price of the Outstanding STRYPES of that
series may, under certain circumstances, rescind and annul such acceleration if
all Events of Default, other than the non-payment of the amount equal to the
aggregate issue price of all the STRYPES of that series due by reason of such
acceleration, have been cured or waived as provided in the Indenture.  See
"Modification and Waiver" below.

  Subject to the provisions of the Indenture relating to the duties of the
Trustee, in case an Event of Default shall occur and be continuing, the Trustee
will be under no obligation to exercise any of its rights or powers under the
Indenture at the request or direction of any of the holders of STRYPES of any
series, unless such holders of that series shall have offered to the Trustee
reasonable security or indemnity against the costs, expenses and liabilities
which might be incurred by it in compliance with such request or direction.
Subject to such provisions for the indemnification of the Trustee, the holders
of a majority of the aggregate issue price of the STRYPES of any series 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 STRYPES of that series.

  The Company will be required to furnish to the Trustee annually a statement by
certain of its officers as to whether or not the Company, to their knowledge, is
in default in the fulfillment of any of its obligations under the Indenture and,
if so, specifying all such known defaults.

  The STRYPES and other series of Senior Debt Securities issued under the
Indenture will not have the benefit of any cross-default provisions with other
indebtedness of the Company.

Modification and Waiver

  Modifications of and amendments to the Indenture affecting a series of STRYPES
may be made by the Company and the Trustee with the consent of the holders of
66/2//3% of the aggregate issue price of the Outstanding STRYPES of such series;
provided, however, that no such modification or amendment may, without the
consent of the holder of each Outstanding STRYPES of such series affected
thereby, (a) change the Maturity Date or the Stated Maturity of any installment
of interest or Additional Amounts on any STRYPES or any premium payable on the
redemption thereof, or change the Redemption Price, (b) reduce the amount of
Underlying Securities payable with respect to any STRYPES (or reduce the amount
of cash payable in lieu thereof), (c) reduce the amount of interest or
Additional Amounts payable on any STRYPES or reduce the amount of cash payable
with respect to any STRYPES upon acceleration of the maturity thereof, (d)
change the place or currency of payment of interest or Additional Amounts on, or
any amount of cash payable with respect to any STRYPES, (e) impair the right to
institute suit for the enforcement of any payment on or with respect to any
STRYPES, including the payment of Underlying Securities with respect to any
STRYPES, (f) reduce the percentage of the aggregate issue price of Outstanding
STRYPES of such series, the consent of whose holders is required to modify or
amend the Indenture, (g) reduce the percentage of the aggregate issue price of
Outstanding STRYPES of such series necessary for waiver of compliance with
certain provisions of the Indenture or for waiver of certain defaults or (h)
modify such provisions with respect to modification and waiver. Except as
provided in the Indenture, no modification of or amendment to the Indenture may
adversely affect the rights of a holder of any other Senior Debt Security
without the consent of such holder.

  The holders of a majority of the aggregate issue price of each series of
STRYPES may waive compliance by the Company with certain restrictive provisions
of the Indenture.  The holders of a majority of the aggregate issue price of
each series of STRYPES may waive any past default under the Indenture, except a
default in the payment of the Underlying Securities with respect to any STRYPES
of that series, or of cash payable in lieu thereof, or in the payment of any
premium, interest or Additional Amounts on any STRYPES of that series for which
payment

                                       15
<PAGE>
 
had not been subsequently made or in respect of a covenant and provision of the
Indenture which cannot be modified or amended without the consent of the holder
of each Outstanding STRYPES of such series affected.

GOVERNING LAW

  The Indenture and the STRYPES are governed by, and construed in accordance
with, the laws of the State of New York.

LISTING

  The STRYPES have been listed on the NYSE under this symbol "SAI."

               CERTAIN ARRANGEMENTS WITH THE SELLING STOCKHOLDER

  Pursuant to an agreement (the "Stock Agreement"), the Selling Stockholder is
obligated to deliver to Merrill Lynch Capital Services, Inc., a wholly owned
subsidiary of the Company (the "ML&Co. Subsidiary), on June 14, 1999, a
specified number of shares of SunAmerica Class B Stock (subject to the Selling
Stockholder's right to deliver cash in an amount equal to the Current Market
Price, determined as of the second Trading Day prior to the applicable Notice
Date, of the SunAmerica Common Stock underlying the SunAmerica Class B Stock
that otherwise would have been delivered). At any time and from time to time
through June 15, 1999, the Selling Stockholder may, at his option, redeem his
obligations under the Stock Agreement in whole or in part, at declining
redemption prices, payable in either (i) shares of SunAmerica Class B Stock
representing SunAmerica Common Stock having an aggregate Current Market Price,
determined as of the second Trading Day prior to the date of the applicable
notice of redemption, equal to the applicable redemption price or (ii) at the
Selling Stockholder's option (which may be exercised with respect to all, but
not less than all, of the obligations to be redeemed), cash, plus in either case
an amount in cash equal to accrued and unpaid interest on the Stock Agreement to
but excluding the redemption date. The consideration paid by the ML&Co.
Subsidiary to the Selling Stockholder under the Stock Agreement is approximately
$131 million, and was paid on June 12, 1996.  In the Indenture, the Company has
agreed to pay and discharge the STRYPES by delivering to the holders thereof on
the Maturity Date or any redemption date the form of consideration that the
ML&Co. Subsidiary receives from the Selling Stockholder and to redeem the
STRYPES if and when the Selling Stockholder redeems his obligations under the
Stock Agreement.

  Shares of SunAmerica Class B Stock delivered by the Selling Stockholder will
convert automatically into shares of SunAmerica Common Stock upon transfer to
the ML&Co. Subsidiary. The Selling Stockholder has the right at any time to
modify the Stock Agreement so that he may deliver shares of SunAmerica Common
Stock (or cash) instead of shares of SunAmerica Class B Stock (or cash). Until
such time, if any, as the Selling Stockholder shall have delivered shares to the
ML&Co. Subsidiary at maturity or upon redemption pursuant to the terms of the
Stock Agreement, the Selling Stockholder will retain all ownership rights with
respect to the shares held by him (including, without limitation, voting rights
and rights to receive any dividends or other distributions in respect thereof).

  The Selling Stockholder has no obligations with respect to the STRYPES or
amounts to be paid to holders thereof including any obligation to take the needs
of the Company or holders of the STRYPES into consideration in determining
whether or when to cause the redemption of the STRYPES or whether to deliver
shares or cash at maturity or upon redemption, or for any other reason.  The
Stock Agreement is a commercial transaction among the parties thereto and does
not create any rights in or for the benefit of, any third party, including any
holder of STRYPES.

  In the event the Selling Stockholder does not perform under the Stock
Agreement, the Company will be required to otherwise acquire shares of
SunAmerica Common Stock for delivery to holders of the STRYPES on the Maturity
Date or upon redemption, unless it elects to exercise its option to deliver cash
with an equal value.

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

   On July 9, 1996, Merrill Lynch & Co., Inc. (the "Company") issued 6,510,286
of its Structured Yield Product Exchangeable for Stock(SM), 6 1/4% STRYPES(SM)
Due July 1, 2001 (each, a "STRYPES"). The issue price of each STRYPES was
$38.25, which amount was equal to the last sale price of the common stock, par
value $1.00 per share (the "IMC Common Stock"), of IMC Global Inc., a Delaware
corporation ("IMC"), on July 2, 1996, as reported on the New York Stock Exchange
(the "Initial Price"). The STRYPES will mature on July 1, 2001 (the "Maturity
Date"). Interest on the STRYPES, at the rate of 6 1/4% of the issue price per
annum, is payable in cash quarterly in arrears on January 1, April 1, July 1 and
October 1, beginning October 1, 1996. The STRYPES are not subject to redemption
or any sinking fund prior to maturity. The STRYPES are unsecured obligations of
the Company ranking pari passu with all of its other unsecured and
unsubordinated indebtedness. See "Description of the STRYPES-Ranking." On the
Maturity Date, the Company will pay and discharge each STRYPES by delivering to
the holder thereof a percentage of each type of Reference Property (subject to
the Company's right to deliver, with respect to all, but not less than all,
Reference Property deliverable on the Maturity Date, cash with an equal value)
determined in accordance with the following formula: (a) if the Reference
Property Value (as defined herein) is greater than or equal to $46.28 (the
"Threshold Appreciation Price"), 82.65% of each type of Reference Property, (b)
if the Reference Property Value is less than the Threshold Appreciation Price
but is greater than the Initial Price, a percentage of each type of Reference
Property, allocated as proportionately as practicable, so that the aggregate
value thereof is equal to the Initial Price and (c) if the Reference Property
Value is less than or equal to the Initial Price, 100% of each type of Reference
Property. The term "Reference Property" shall mean initially one share of IMC
Common Stock and shall be subject to adjustment from time to time prior to the
Maturity Date to reflect the addition or substitution of any cash, securities
and/or other property resulting from the application of the adjustment
provisions described herein. AS DESCRIBED HEREIN, THE REFERENCE PROPERTY VALUE
WILL REPRESENT A DETERMINATION OF THE VALUE OF THE REFERENCE PROPERTY
IMMEDIATELY PRIOR TO THE MATURITY DATE. ACCORDINGLY, THERE CAN BE NO ASSURANCE
THAT THE AMOUNT RECEIVABLE BY HOLDERS OF THE STRYPES ON THE MATURITY DATE WILL
BE EQUAL TO OR GREATER THAN THE ISSUE PRICE OF THE STRYPES. IF THE REFERENCE
PROPERTY VALUE IS LESS THAN THE INITIAL PRICE, SUCH AMOUNT RECEIVABLE ON THE
MATURITY DATE WILL BE LESS THAN THE ISSUE PRICE PAID FOR THE STRYPES, IN WHICH
CASE AN INVESTMENT IN THE STRYPES WILL RESULT IN A LOSS. See "Description of the
STRYPES."

   IMC is not affiliated with the Company and has no obligation with respect to
    the STRYPES.

                                  RISK FACTORS

COMPARISON TO OTHER DEBT SECURITIES; RELATIONSHIP TO IMC COMMON STOCK

  The terms of the STRYPES differ from those of ordinary debt securities in that
the value of the Reference Property (or, pursuant to the option of the Company,
the amount of cash) that a holder of a STRYPES will receive on the Maturity Date
is not fixed, but is based on the Reference Property Value (see "Description of
the STRYPES"). THERE CAN BE NO ASSURANCE THAT SUCH AMOUNT RECEIVABLE BY THE
HOLDER ON THE MATURITY DATE WILL BE EQUAL TO OR GREATER THAN THE ISSUE PRICE OF
THE STRYPES. IF THE REFERENCE PROPERTY VALUE IS LESS THAN THE INITIAL PRICE,
SUCH AMOUNT RECEIVABLE ON THE MATURITY DATE WILL BE LESS THAN THE ISSUE PRICE
PAID FOR THE STRYPES, IN WHICH CASE AN INVESTMENT IN STRYPES WILL RESULT IN A
LOSS. ACCORDINGLY, A HOLDER OF STRYPES ASSUMES THE RISK THAT THE MARKET VALUE OF
THE REFERENCE PROPERTY MAY DECLINE, AND THAT SUCH DECLINE COULD BE SUBSTANTIAL.
THE IMC PROSPECTUS COVERS THE SHARES OF IMC COMMON STOCK (INCLUDING THE
PREFERRED STOCK PURCHASE RIGHTS ASSOCIATED THEREWITH) WHICH MAY BE RECEIVED BY A
HOLDER OF THE STRYPES ON THE MATURITY DATE.

LIMITATION ON OPPORTUNITY FOR EQUITY APPRECIATION

  The opportunity for equity appreciation afforded by an investment in the
STRYPES is less than the opportunity for equity appreciation afforded by a
direct investment in the IMC Common Stock because the amount receivable by a
holder of a STRYPES on the Maturity Date will only exceed the issue price of
such STRYPES if the Reference Property Value exceeds the Threshold Appreciation
Price (which represents an appreciation of 21% over the Initial Price).
Moreover, holders of the STRYPES will only be entitled to receive on the
Maturity Date 82.65% (the percentage equal to the Initial Price divided by the
Threshold Appreciation Price) of any appreciation of the value of the Reference
Property in excess of the Threshold Appreciation Price. See "Description of the
STRYPES." Because the price of the Reference Property is subject to market
fluctuations, the value of the Reference Property (or, pursuant to the option of
the Company, the amount of cash) received by a holder of a STRYPES on the
Maturity Date, determined as described herein, may be more or less than the
issue price of the STRYPES.

FACTORS AFFECTING TRADING PRICES

  The trading prices of the STRYPES in the secondary market will be directly
affected by the trading prices of the IMC Common Stock in the secondary market.
It is impossible to predict whether the price of IMC Common Stock will rise or
fall. Trading prices of IMC Common Stock will be influenced by IMC's operating
results and prospects, by complex and interrelated political, economic,
financial and other factors and market conditions that can affect the capital
markets generally, the market segment of which IMC is a part, the NYSE (on which
the IMC Common Stock is traded), including the level of, and fluctuations in,
the trading prices of stocks generally and sales of substantial amounts of IMC
Common Stock in the market subsequent to the offering of the STRYPES or the
perception that such sales could occur, and by other events that are difficult
to predict and are beyond the Company's control.

IMPACT OF STRYPES ON THE MARKET FOR IMC COMMON STOCK

  It is not possible to predict accurately how the STRYPES will trade in the
secondary market or whether such market will be liquid. Any market that develops
for the STRYPES is likely to influence and be influenced by the market for IMC
Common Stock. For example, the price of IMC Common Stock could become more
volatile and could be depressed by investors' anticipation of the potential
distribution into the market of substantial amounts of

                                       3
<PAGE>
 
IMC Common Stock on the Maturity Date, by possible sales of IMC Common Stock by
investors who view the STRYPES as a more attractive means of equity
participation in IMC, and by hedging or arbitrage trading activity that may
develop involving the STRYPES and the IMC Common Stock.

POSSIBLE ILLIQUIDITY OF THE SECONDARY MARKET

  It is not possible to predict how the STRYPES will trade in the secondary
market or whether such market will be liquid or illiquid.  The STRYPES are novel
securities and there is currently no secondary market for the STRYPES. The
STRYPES have been approved for listing on the NYSE, subject to official notice
of issuance. However there can be no assurance that an active trading market for
the STRYPES will develop, that such listing will provide the holders of the
STRYPES with liquidity of investment, or that the STRYPES will not later be
delisted or that trading of the STRYPES on the NYSE will not be suspended.  In
the event of a delisting or suspension of trading on the NYSE, the Company will
apply for listing of the STRYPES on another national securities exchange or for
quotation on another trading market. If the STRYPES are not listed or traded on
any securities exchange or trading market, or if trading of the STRYPES is
suspended, pricing information for the STRYPES may be more difficult to obtain
and the liquidity of the STRYPES may be adversely affected.

NO STOCKHOLDER'S RIGHTS

  Holders of the STRYPES will not be entitled to any rights with respect to the
Reference Property (including, without limitation, voting rights and rights to
receive any dividends, interest or other distributions in respect thereof)
unless and until such time, if any, as the Company shall have delivered the
Reference Property for STRYPES on the Maturity Date, and unless the applicable
record date, if any, for the exercise of such rights occurs after such delivery.
For example, in the event that an amendment is proposed to the Restated
Certificate of Incorporation of IMC and the record date for determining the
stockholders of record entitled to vote on such amendment occurs prior to such
delivery, holders of the STRYPES will not be entitled to vote on such amendment.

NO AFFILIATION BETWEEN THE COMPANY AND IMC

  The Company has no affiliation with IMC, and IMC has no obligations with
respect to the STRYPES or amounts to be paid to holders thereof, including any
obligation to take the needs of the Company or of holders of the STRYPES into
consideration for any reason. IMC will not receive any of the proceeds of the
offering of the STRYPES made hereby and is not responsible for, and has not
participated in, the determination of the timing of, prices for or quantities of
the STRYPES to be issued, or the determination or calculation of the amount
receivable by holders of the STRYPES on the Maturity Date. IMC is not involved
with the administration or trading of the STRYPES and has no obligations with
respect to the amount receivable by holders of the STRYPES on the Maturity Date.

DILUTION OF IMC COMMON STOCK

  The Reference Property (or, pursuant to the option of the Company, the amount
of cash) that holders of the STRYPES are entitled to receive on the Maturity
Date is subject to adjustment for certain events arising from, among others, a
merger or consolidation in which IMC is not the surviving or resulting
corporation and the liquidation, dissolution, winding up or bankruptcy of IMC,
as well as stock splits and combinations, stock dividends and certain other
actions of IMC that modify its capital structure. See "Description of the
STRYPES--Reference Property Adjustments." Such Reference Property (or cash
amount) to be received by such holders on the Maturity Date will not be adjusted
for other events, such as offerings of IMC Common Stock for cash or in
connection with acquisitions. IMC is not restricted from issuing additional
shares of IMC Common Stock during the term of the STRYPES and has no obligation
to consider the interests of the holders of the STRYPES for any reason.
Additional issuances may materially and adversely affect the price of the IMC
Common Stock and, because of the relationship of the percentage of the Reference
Property (or cash amount) to be received on the Maturity Date to the price of
the IMC Common Stock, such other events may adversely affect the trading price
of the STRYPES.

TAX MATTERS

  Because of an absence of authority as to the proper characterization of the
STRYPES, their ultimate tax treatment is uncertain. Accordingly, no assurances
can be given that any particular characterization and treatment of the STRYPES
will be accepted by the Internal Revenue Service ("IRS") or upheld by a court.
However, it is the opinion of Brown & Wood LLP, counsel to the Company, that the
characterization and tax treatment of the STRYPES described herein, while not
the only reasonable characterization and tax treatment, is based on reasonable
interpretations of law currently in effect and, even if successfully challenged
by the IRS, will not result in the imposition of penalties. The Indenture (as
defined below) will require that any holder subject to U.S. Federal income tax
include currently in income, for U.S. Federal income tax purposes, payments
denominated as interest that are made with respect to a STRYPES in accordance
with such holder's regular method of tax accounting. The Indenture also requires
the Company and holders to treat each STRYPES for tax purposes as a unit (a
"Unit") consisting of (i) a debt instrument (the "Debt Instrument") with a fixed
principal amount unconditionally payable on the Maturity Date equal to the issue
price of the STRYPES and bearing interest at the stated interest rate on the
STRYPES and (ii) a forward purchase contract (the "Forward Contract") pursuant
to which the holder agrees to use the principal payment due on the Debt
Instrument to purchase on the Maturity Date the Reference Property which the
Company is obligated under the STRYPES to deliver at that time (subject to the
Company's right to deliver cash in lieu of the Reference Property). The
Indenture also requires that upon the acquisition of a STRYPES and upon a
holder's sale or other disposition of a STRYPES prior to the Maturity Date, the
amount paid or realized by the holder be allocated by the holder between the
Debt Instrument and the Forward Contract based upon their relative fair market
values (as determined on the date of acquisition or disposition). For these
purposes, with respect to acquisitions of STRYPES in connection with the
original issuance thereof, the Company and each holder agrees, pursuant to the
terms of the Indenture, to allocate $37.045 of the entire initial purchase price
of a STRYPES (i.e., the issue price of a STRYPES) to the Debt Instrument and to
allocate the remaining $1.205 of the entire initial purchase price of a STRYPES
to the Forward Contract. As a result of this allocation, the Debt Instrument
will be treated as having been issued with original issue discount for United
States Federal income tax purposes. As previously mentioned, the appropriate
character and timing of income, gain or loss to be recognized on a STRYPES is
uncertain and investors should consult their own tax advisers concerning the
application of the United States Federal income tax laws to their particular
situations as well as any consequences of the purchase, ownership and
disposition of the STRYPES arising under the laws of any other taxing
jurisdiction.

HOLDING COMPANY STRUCTURE

  Since the Company is a holding company, the right of the Company, and hence
the right of creditors of the Company (including the holders of the STRYPES), to
participate in any distribution of the assets of any subsidiary upon its
liquidation or reorganization or otherwise is necessarily subject to the prior
claims of creditors of the subsidiary, except to the extent that claims of the
Company itself as a creditor of the subsidiary may be recognized. In addition,
dividends, loans and advances from certain subsidiaries, including MLPF&S, to
the Company are restricted by net capital requirements under the Exchange Act
and under rules of certain exchanges and other regulatory bodies.

STOCK. THE IMC PROSPECTUS DOES NOT CONSTITUTE A PART OF THIS PROSPECTUS, NOR IS
IT INCORPORATED BY REFERENCE HEREIN.

                           DESCRIPTION OF THE STRYPES

  The STRYPES are a series of Senior Debt Securities issued under an indenture
dated as of April 1, 1983 and restated as of April 1, 1987, as amended and
supplemented as of July 1, 1995 (the indenture dated as of April 1, 1983 and
restated as of April 1, 1987, as amended and supplemented from time to time, the
"Indenture") between the Company and The Chase Manhattan Bank, formerly known as
Chemical Bank (successor by merger to Manufacturers Hanover Trust Company), as
trustee (the "Trustee"). The following summary of certain provisions of the
Indenture does not purport to be complete and is qualified in its entirety by
reference to the Indenture, a copy of which is filed as an exhibit to the
Registration Statement of which this Prospectus is a part. All capitalized terms
not otherwise defined herein have the meanings specified in the Indenture.
Whenever defined terms of the Indenture are referred to herein, such defined
terms are incorporated by reference herein.
 
GENERAL

  Each STRYPES, was issued at a price of $38.25, bears interest at the rate of
6 1/4% of the issue price per annum (or $2.3908 per annum) from July 9, 1996,
or from the most recent Interest Payment Date to which interest has been paid or
provided for, until the Maturity Date or such earlier date on which such STRYPES
is repaid pursuant to the terms thereof. Interest on the STRYPES is payable in
cash quarterly in arrears on January 1, April 1, July 1 and October 1, beginning
October 1, 1996, and on the Maturity Date (each, an "Interest Payment Date"), to
the persons in whose names the STRYPES are registered at the close of business
on the fifteenth calendar day (whether or not a Business Day) immediately
preceding such Interest Payment Date. Interest on the STRYPES will be computed
on the basis of a 360-day year of twelve 30-day months. If an Interest Payment
Date falls on a day that is not a Business Day, the interest payment to be made
on such Interest Payment Date will be made on the next succeeding Business Day
with the same force and effect as if made on such Interest Payment Date, and no
additional interest will accrue as a result of such delayed payment.

  The STRYPES will mature on July 1, 2001. On the Maturity Date, the Company
will pay and discharge each STRYPES by delivering to the holder thereof a
percentage of each type of Reference Property (subject to the Company's right to
deliver, with respect to all, but not less than all, Reference Property
deliverable on the Maturity Date, cash with an equal value) determined in
accordance with the following formula: (a) if the Reference Property Value (as
defined below) is greater than or equal to the Threshold Appreciation Price,
82.65% of each type of Reference Property, (b) if the Reference Property Value
is less than the Threshold Appreciation Price but is greater than the Initial
Price, a percentage of each type of Reference Property, allocated as
proportionately as practicable, so that the aggregate value thereof is equal to
the Initial Price and (c) if the Reference Property Value is less than or equal
to the Initial Price, 100% of each type of Reference Property. ACCORDINGLY,
THERE CAN BE NO ASSURANCE THAT THE AMOUNT RECEIVABLE BY HOLDERS OF THE STRYPES
ON THE MATURITY DATE WILL BE EQUAL TO OR GREATER THAN THE ISSUE PRICE OF THE
STRYPES. IF THE REFERENCE PROPERTY VALUE IS LESS THAN THE INITIAL PRICE, SUCH
AMOUNT RECEIVABLE ON THE MATURITY DATE WILL BE LESS THAN THE ISSUE PRICE PAID
FOR THE STRYPES, IN WHICH CASE AN INVESTMENT IN STRYPES WILL RESULT IN A LOSS.

  Notwithstanding the foregoing, the Company may, in lieu of delivering the
applicable percentage of each type of Reference Property, deliver cash in an
amount equal to the sum of (a) for any portion of the Reference Property

                                       7
<PAGE>
 
consisting of cash that is otherwise deliverable on the Maturity Date, the
amount of such cash, without interest thereon, (b) for any portion of the
Reference Property consisting of property other than cash or Reference
Securities that is otherwise deliverable on the Maturity Date, the fair market
value (as determined by a nationally recognized independent investment banking
firm retained for this purpose by the Company) as of the third Trading Day
preceding the Maturity Date of such property, and (c) for any portion of the
Reference Property consisting of a Reference Security (as defined below) that is
otherwise deliverable on the Maturity Date (except as described under "Reference
Property Adjustments" below), an amount equal to the average Closing Price (as
defined below) per unit of such Reference Security on the 20 Trading Days
immediately prior to, but not including, the second Trading Day preceding the
Maturity Date multiplied by the number of units of such Reference Security
constituting part of the Reference Property, subject to the Company's agreement
contained in the Purchase Agreement to deliver on the Maturity Date the form of
consideration that the ML&Co. Subsidiary (as defined below) receives from GVI.
Such right, if exercised by the Company, must be exercised with respect to all
Reference Property otherwise deliverable on the Maturity Date in payment of all
outstanding STRYPES. On or prior to the sixth Business Day prior to the Maturity
Date, the Company will notify The Depository Trust Company and the Trustee and
publish a notice in The Wall Street Journal or another daily newspaper of
national circulation stating whether the STRYPES will be paid and discharged by
delivery of the applicable percentage of each type of Reference Property or
cash. At the time such notice is published, the Reference Property Value will
not have been determined. If the Company elects to deliver Reference Property,
holders of the STRYPES will be responsible for the payment of any and all
brokerage costs upon the subsequent sale thereof.

  The term "Reference Property" initially means one share of IMC Common Stock
and shall be subject to adjustment from time to time prior to the Maturity Date
to reflect the addition or substitution of any cash, securities and/or other
property resulting from the application of the adjustment provisions described
herein. See "--Reference Property Adjustments" below. The term "Reference
Security" means, at any time, any security (as defined in Section 2(1) of the
Securities Act) then constituting part of the Reference Property. The term
"Reference Property Value" means, subject to the adjustment provisions described
below, the sum of (a) for any portion of the Reference Property consisting of
cash, the amount of such cash, (b) for any portion of the Reference Property
consisting of property other than cash or Reference Securities, the fair market
value (as determined by a nationally recognized independent investment banking
firm retained for this purpose by the Company) as of the third Trading Day
preceding the Maturity Date of such property, and (c) for any portion of the
Reference Property consisting of a Reference Security, an amount equal to the
average Closing Price per unit of such Reference Security on the 20 Trading Days
immediately prior to, but not including, the second Trading Day preceding the
Maturity Date multiplied by the number of units of such Reference Security
constituting part of the Reference Property. The "Closing Price" of any
Reference Security on any date of determination means the closing sale price
(or, if no closing price is reported, the last reported sale price) of such
Reference Security on the NYSE on such date or, if such Reference Security is
not listed for trading on the NYSE on any such date, as reported in the
composite transactions for the principal United States securities exchange on
which such Reference Security is so listed, or if such Reference Security is not
so listed on a United States national or regional securities exchange, as
reported by the National Association of Securities Dealers, Inc. Automated
Quotation System, or, if such Reference Security is not so reported, the last
quoted bid price for such Reference Security in the over-the-counter market as
reported by the National Quotation Bureau or similar organization, or, if such
bid price is not available, the market value of such Reference Security on such
date as determined by a nationally recognized independent investment banking
firm retained for this purpose by the Company. A "Trading Day" is defined as a
day on which the Reference Security the Closing Price of which is being
determined (A) is not suspended from trading on any national or regional
securities exchange or association or over-the-counter market at the close of
business and (B) has traded at least once on the national or regional securities
exchange or association or over-the-counter market that is the primary market
for the trading of such Reference Security.

  For illustrative purposes only, the following table shows the number of shares
of IMC Common Stock or the amount of cash that a holder of STRYPES would receive
for each STRYPES at various Reference Property Values. The table assumes that
there will be no Reference Property adjustments as described below and,
accordingly, that 

                                       8
<PAGE>
 
on the Maturity Date the Reference Property will consist of one share of IMC
Common Stock. There can be no assurance that the Reference Property Value will
be within the range set forth below. Given the Initial Price of $38.25 and the
Threshold Appreciation Price of $46.28, a STRYPES holder would receive on the
Maturity Date the following number of shares of IMC Common Stock or amount of
cash (if the Company elects to pay and discharge the STRYPES with cash) per
STRYPES:

REFERENCE PROPERTY ADJUSTMENTS

  The Reference Property is subject to adjustment if an issuer of a Reference
Security shall: (i) subdivide or split the outstanding units of such Reference
Security into a greater number of units; (ii) combine the outstanding units of
such Reference Security into a smaller number of units; (iii) issue by
reclassification of units of such Reference Security any units of another
security of such issuer; (iv) issue rights or warrants to all holders of such
Reference Security entitling them, for a period expiring prior to the fifteenth
calendar day following the Maturity Date, to subscribe for or purchase any of
its securities or other property (other than rights to purchase units of such
Reference Security pursuant to a plan for the reinvestment of dividends or
interest); or (v) pay a dividend or make a distribution to all holders of such
Reference Security of cash, securities or other property (excluding any cash
dividend on any Reference Security consisting of capital stock that does not
constitute an Extraordinary Cash Dividend (as defined below), excluding any
payment of interest on any Reference Security consisting of an evidence of
indebtedness and excluding any dividend or distribution referred to in clause
(i), (ii), (iii) or (iv) above) or issue to all holders of such Reference
Security rights or warrants to subscribe for or purchase any of its securities
or other property (other than those referred to in clause (iv) above) (any of
the foregoing cash, securities or other property or rights or warrants are
referred to as the "Distributed Assets").

  In the case of the events referred to in clauses (i), (ii) and (iii) above,
the Reference Property shall be adjusted to include the number of units of such
Reference Security and/or other security of such issuer which a holder of units
of such Reference Security would have owned or been entitled to receive
immediately following any such event had such holder held, immediately prior to
such event, the number of units of such Reference Security constituting part of
the Reference Property immediately prior to such event. Each such adjustment
shall become effective immediately after the effective date for such
subdivision, split, combination or reclassification, as the case may be. Each
such adjustment shall be made successively.

  In the case of the event referred to in clause (iv) above, the Reference
Property shall be adjusted to include an amount in cash equal to the fair market
value (determined as described below), as of the fifth Business Day (except as
provided below) following the date on which such rights or warrants are received
by securityholders entitled thereto (the "Receipt Date"), of each such right or
warrant multiplied by the product of (A) the number of such rights or warrants
issued for each unit of such Reference Security and (B) the number of units of
such Reference Security constituting part of the Reference Property on the date
of issuance of such rights or warrants, immediately prior to such issuance,
without interest thereon. For purposes of the foregoing, the fair market value
of each such right or warrant shall be the quotient of (x) the highest net bid,
as of approximately 10:00 A.M., New York City time, on the fifth Business Day
following the Receipt Date for settlement three Business Days later, by a
recognized securities dealer in The City of New York selected by or on behalf of
the Company (from three (or such fewer number of dealers as may be providing
such bids) such recognized dealers selected by or on behalf of the Company), for
the 

                                       9
<PAGE>
 
purchase by such quoting dealer of the number of rights or warrants (the
"Aggregate Number") that a holder of such Reference Security would receive if
such holder held, as of the record date for determination of stockholders
entitled to receive such rights or warrants, a number of units of such Reference
Security equal to the product of (1) the aggregate number of Outstanding STRYPES
as of such record date and (2) the number of units of such Reference Security
constituting part of the Reference Property, divided by (y) the Aggregate
Number. Each such adjustment shall become effective on the fifth Business Day
following the Receipt Date of such rights or warrants. If for any reason the
Company is unable to obtain the required bid on the fifth Business Day following
the Receipt Date, it shall attempt to obtain such bid at successive intervals of
three months thereafter and on the third Trading Day prior to the Maturity Date
until it is able to obtain the required bid. From the date of issuance of such
rights or warrants until the required bid is obtained, the Reference Property
shall include the number of such rights or warrants issued for each unit of such
Reference Security multiplied by the number of units of such Reference Security
constituting part of the Reference Property on the date of issuance of such
rights or warrants, immediately prior to such issuance, and such rights or
warrants constituting part of the Reference Property shall be deemed for all
purposes hereof to have a fair market value of zero.

  In the case of the event referred to in clause (v) above, the Reference
Property shall be adjusted to include, from and after such dividend,
distribution or issuance, (x) in respect of that portion, if any, of the
Distributed Assets consisting of cash, the amount of such Distributed Assets
consisting of cash received for each unit of such Reference Security multiplied
by the number of units of such Reference Security constituting part of the
Reference Property on the date of such dividend, distribution or issuance,
immediately prior to such dividend, distribution or issuance, without interest
thereon, plus (y) in respect of that portion, if any, of the Distributed Assets
which are other than cash, the number or amount of each type of Distributed
Assets other than cash received with respect to each unit of such Reference
Security multiplied by the number of units of such Reference Security
constituting part of the Reference Property on the date of such dividend,
distribution or issuance, immediately prior to such dividend, distribution or
issuance.

  An "Extraordinary Cash Dividend" means, with respect to any consecutive 12-
month period, the amount, if any, by which the aggregate amount of all cash
dividends on any Reference Security consisting of capital stock occurring in
such 12-month period (or, if such Reference Security was not outstanding at the
commencement of such 12-month period, occurring in such shorter period during
which such Reference Security was outstanding) exceeds on a per share basis 12%
of the average of the Closing Prices per share of such Reference Security over
such 12-month period (or such shorter period during which such Reference
Security was outstanding); provided that, for purposes of the foregoing
definition, the amount of cash dividends paid on a per share basis will be
appropriately adjusted to reflect the occurrence during such period of any stock
dividend or distribution of shares of capital stock of the issuer of such
Reference Security or any subdivision, split, combination or reclassification of
shares of such Reference Security.

  In the event of (A) any consolidation or merger of an issuer of a Reference
Security with or into another entity (other than a merger or consolidation in
which such issuer is the continuing corporation and in which the Reference
Security outstanding immediately prior to the merger or consolidation is not
exchanged for cash, securities or other property of such issuer or another
entity), (B) any statutory exchange of securities of an issuer of a Reference
Security with another entity (other than in connection with a merger or
acquisition) or (C) any liquidation, dissolution, winding up or bankruptcy of an
issuer of a Reference Security (excluding any distribution in such event
referred to in clause (v) above) (any such event described in clause (A), (B) or
(C), a "Reorganization Event"), the Reference Property shall be adjusted to
include, from and after the effective date for such Reorganization Event, in
lieu of the number of units of such Reference Security constituting part of the
Reference Property immediately prior to the effective date for such
Reorganization Event, the amount or number of any cash, securities and/or other
property owned or received in such Reorganization Event with respect to each
unit of such Reference Security multiplied by the number of units of such
Reference Security constituting part of the Reference Property immediately prior
to the effective date for such Reorganization Event.

  No adjustments will be made for certain other events, such as offerings of IMC
Common Stock by IMC for cash or in connection with acquisitions. Likewise, no
adjustments will be made for any sales of IMC Common Stock by 

                                       10
<PAGE>
 
GVI.

  The Company is required, within ten Business Days following the occurrence of
an event that requires an adjustment to the Reference Property (or if the
Company is not aware of such occurrence, as soon as practicable after becoming
so aware), to provide written notice to the Trustee and to the holders of the
STRYPES of the occurrence of such event and a statement in reasonable detail
setting forth the amount or number of each type of Reference Security and other
property then constituting part of the Reference Property.

FRACTIONAL INTERESTS

  No fractional units of any Reference Security will be delivered if the Company
pays and discharges the STRYPES by delivering Reference Property. In lieu of any
fractional unit otherwise deliverable in respect of all STRYPES of any holder on
the Maturity Date, such holder shall be entitled to receive an amount in cash
equal to the value of such fractional unit based on the average Closing Price
per unit of such Reference Security on the 20 Trading Days immediately prior to,
but not including, the second Trading Day preceding the Maturity Date.

  To the extent practicable, the Company will deliver fractional interests of
any Reference Property other than cash or a Reference Security if the Company
pays and discharges the STRYPES by delivering Reference Property. If such
delivery is not practicable, in lieu of delivering any such fractional interest
otherwise deliverable in respect of all STRYPES of any holder on the Maturity
Date, such holder shall be entitled to receive an amount in cash equal to the
value of such fractional interest based on the fair market value (as determined
by a nationally recognized independent investment banking firm retained for this
purpose by the Company) as of the third Trading Day preceding the Maturity Date
of such Reference Property other than cash or a Reference Security.

REDEMPTION, SINKING FUND AND PAYMENT PRIOR TO MATURITY

  The STRYPES are not subject to redemption by the Company prior to the Maturity
Date and do not contain sinking fund or other mandatory redemption provisions.
The STRYPES are not subject to payment prior to the Maturity Date at the option
of the holder.

RANKING

  The STRYPES are unsecured obligations and will rank pari passu with all other
unsecured and unsubordinated indebtedness of the Company.

  There are no contractual restrictions on the ability of the Company or its
subsidiaries to incur additional secured or unsecured debt. However, borrowings
by certain subsidiaries, including MLPF&S, are restricted by net capital
requirements under the Exchange Act and under rules of certain exchanges and
other regulatory bodies.

PURCHASE AGREEMENT

  Pursuant to the Purchase Agreement described under "Certain Arrangements with
GVI," GVI is obligated to deliver to the ML&Co. Subsidiary (as defined below)
immediately prior to the Maturity Date the Reference Property required by the
Company to pay and discharge all of the STRYPES (including any STRYPES issued
pursuant to the over-allotment option granted by the Company to MLPF&S). In lieu
of delivering the Reference Property immediately prior to the Maturity Date, GVI
has the right to satisfy its obligation under the Purchase Agreement by
delivering at such time cash in an amount equal to the value of such Reference
Property immediately prior to the Maturity Date. Such right, if exercised by
GVI, must be exercised with respect to all of the Reference Property deliverable
pursuant to the Purchase Agreement.

                                       11

SECURITIES DEPOSITORY

  Upon issuance, all STRYPES were represented by one or more fully registered
global securities (the "Global Notes"). Each such Global Note was deposited
with, or on behalf of, The Depository Trust Company, as Securities Depository
(the "Securities Depository"), and registered in the name of the Securities
Depository or a nominee thereof. Unless and until it is exchanged in whole or in
part for STRYPES in definitive form under the limited circumstances described
below, no Global Note may be transferred except as a whole by the Securities
Depository to a nominee of such Securities Depository or by a nominee of such
Securities Depository to such Securities Depository or another nominee of such
Securities Depository or by such Securities Depository or any such nominee to a
successor of such Securities Depository or a nominee of such successor.

  The Securities Depository has advised the Company as follows: The Securities
Depository is a limited-purpose trust company organized under the Banking Law of
the State of New York, a member of the Federal Reserve System, a "clearing
corporation" within the meaning of the New York Uniform Commercial Code, and a
"clearing agency" registered pursuant to the provisions of Section 17A of the
Exchange Act.  The Securities Depository was created to hold securities of its
participants ("Participants") and to facilitate the clearance and settlement of
securities transactions among its Participants in such securities through
electronic book-entry changes in accounts of the Participants, thereby
eliminating the need for physical movement of securities certificates. The
Securities Depository's Participants include securities brokers and dealers
(including MLPF&S), banks, trust companies, clearing corporations, and certain
other organizations.

  The Securities Depository is owned by a number of Participants and by the New
York Stock Exchange, Inc., the American Stock Exchange, Inc. and the National
Association of Securities Dealers, Inc. Access to the Securities Depository's
book-entry system is also available to others, such as banks, brokers, dealers
and trust companies that clear through or maintain a custodial relationship with
a Participant, either directly or indirectly ("Indirect Participants").

  Purchases of STRYPES must be made by or through Participants, which will
receive a credit on the records of the Securities Depository. The ownership
interest of each actual purchaser of each STRYPES ("Beneficial Owner") is in
turn to be recorded on the Participants' or Indirect Participants' records.
Beneficial Owners will not receive written confirmations from the Securities
Depository of their purchase, but Beneficial Owners are expected to receive
written confirmation providing details of the transaction, as well as periodic
statements of their holdings, from the Participant or Indirect Participant
through which the Beneficial Owner entered into the transaction. Ownership of
beneficial interest in such Global Note will be shown on, and the transfer of
such ownership interests will be effected only through, records maintained by
the Securities Depository (with respect to interests of Participants) and on the
records of Participants (with respect to interests of persons held through
Participants). The laws of some states may require that certain purchasers of
securities take physical delivery of such securities in definitive form. Such
limits and such laws may impair the ability to own, transfer or pledge
beneficial interests in Global Notes.

  So long as the Securities Depository, or its nominee, is the registered owner
of a Global Note, the Securities Depository or its nominee, as the case may be,
will be considered the sole owner or holder of the STRYPES represented by such
Global Note for all purposes under the Indenture. Except as provided below,
Beneficial Owners in a Global Note will not be entitled to have the STRYPES
represented by such Global Notes registered in their names, will not receive or
be entitled to receive physical delivery of the STRYPES in definitive form and
will not be considered the owners or holders thereof under the Indenture.
Accordingly, each Person owning a beneficial interest in a Global Note must rely
on the procedures of the Securities Depository and, if such Person is not a
Participant, on the procedures of the Participant through which such Person owns
its interest, to exercise any rights of a holder under the Indenture. The
Company understands that under existing industry practices, in the event that
the Company requests any action of holders or that an owner of a beneficial
interest in such a Global Note desires to give or take any action which a holder
is entitled to give or take under the Indenture, the Securities Depository would
authorize the Participants holding the relevant beneficial interests to give or
take such action, and such Participants would

                                       12
<PAGE>
 
authorize Beneficial Owners owning through such Participants to give or take
such action or would otherwise act upon the instructions of Beneficial Owners.
Conveyance of notices and other communications by the Securities Depository to
Participants, by Participants to Indirect Participants, and by Participants and
Indirect Participants to Beneficial Owners will be governed by arrangements
among them, subject to any statutory or regulatory requirements as may be in
effect from time to time.

  Payment of any amount with respect to STRYPES registered in the name of the
Securities Depository or its nominee will be made to the Securities Depository
or its nominee, as the case may be, as the holder of the Global Notes
representing such STRYPES. None of the Company, the Trustee or any other agent
of the Company or agent of the Trustee will have any responsibility or liability
for any aspect of the records relating to or payments made on account of
beneficial ownership interests or for supervising or reviewing any records
relating to such beneficial ownership interests. The Company expects that the
Securities Depository, upon receipt of any payment in respect of a Global Note,
will credit the accounts of the Participants with payment in amounts
proportionate to their respective holdings of beneficial interest in such Global
Note as shown on the records of the Securities Depository. The Company also
expects that payments by Participants to Beneficial Owners will be governed by
standing customer instructions and customary practices, as is now the case with
securities held for the accounts of customers in bearer form or registered in
"street name," and will be the responsibility of such Participants.

  If, with respect to a series of STRYPES, (x) the Securities Depository is at
any time unwilling or unable to continue as Securities Depository and a
successor depository is not appointed by the Company within 60 days, (y) the
Company executes and delivers to the Trustee a Company Order to the effect that
the Global Notes shall be exchangeable or (z) an Event of Default has occurred
and is continuing with respect to any STRYPES of that series, the Company will
issue STRYPES in definitive form in exchange for all of the Global Notes
representing the STRYPES of that series. Such definitive STRYPES shall be
registered in such name or names as the Securities Depository shall instruct the
Trustee. It is expected that such instructions may be based upon directions
received by the Securities Depository from Participants with respect to
ownership of beneficial interests in such Global Notes.

MERGER AND CONSOLIDATION

  The Company may consolidate or merge with or into any other corporation, and
the Company may sell, lease or convey all or substantially all of its assets to
any corporation, provided that (i) the corporation (if other than the Company)
formed by or resulting from any such consolidation or merger or which shall have
received such assets shall be a corporation organized and existing under the
laws of the United States of America or a state thereof and shall assume the due
and punctual delivery or payment of the Underlying Securities (or cash with an
equal value) in respect of, any interest and Additional Amounts on, and any
other amounts payable with respect to, the STRYPES of each series and the due
and punctual performance and observance of all of the covenants and conditions
of the Indenture to be performed or observed by the Company, and (ii) the
Company or such successor corporation, as the case may be, shall not immediately
thereafter be in default under the Indenture.

LIMITATIONS UPON LIENS

  The Indenture provides that the Company may not, and may not permit any
Subsidiary (defined in the Indenture as any corporation of which at the time of
determination the Company and/or one or more Subsidiaries owns or controls
directly or indirectly 50% of the shares of Voting Stock of such corporation)
to, create, assume, incur or permit to exist any indebtedness for borrowed money
secured by a pledge, lien or other encumbrance (except for certain liens
specifically permitted by the Indenture) on the Voting Stock owned directly or
indirectly by the Company of any Subsidiary (other than a Subsidiary which, at
the time of incurrence of such secured indebtedness, has a net worth of less
than $3,000,000) without making effective provision whereby the Outstanding
STRYPES will be secured equally and ratably with such secured indebtedness.

                                       13
<PAGE>
 
LIMITATIONS ON DISPOSITION OF VOTING STOCK OF, AND MERGER AND SALE OF ASSETS BY,
MLPF&S

  The Indenture provides that the Company may not sell, transfer or otherwise
dispose of any Voting Stock of MLPF&S or permit MLPF&S to issue, sell or
otherwise dispose of any of its Voting Stock, unless, after giving effect to any
such transaction, MLPF&S remains a Controlled Subsidiary (defined in the
Indenture to mean a corporation more than 80% of the outstanding shares of
Voting Stock of which are owned directly or indirectly by the Company). In
addition, the Indenture provides that the Company may not permit MLPF&S to (i)
merge or consolidate, unless the surviving company is a Controlled Subsidiary,
or (ii) convey or transfer its properties and assets substantially as an
entirety, except to one or more Controlled Subsidiaries.

EVENTS OF DEFAULT

  Each of the following will constitute an Event of Default under the Indenture
with respect to each series of STRYPES: (a) failure to pay and discharge the
STRYPES of that series with the Underlying Securities or, if the Company so
elects, to pay an equivalent amount in cash in lieu thereof when due; (b)
failure to pay the Redemption Price or any redemption premium with respect to
any STRYPES of that series when due; (c) failure to deposit any sinking fund
payment, when and as due by the terms of any STRYPES of that series; (d) failure
to pay any interest on or any Additional Amounts in respect of any STRYPES of
that series when due, continued for 30 days; (e) failure to perform any other
covenant of the Company contained in the Indenture for the benefit of that
series or in the STRYPES of that series, continued for 60 days after written
notice has been given to the Company by the Trustee, or to the Company and the
Trustee by the holders of at least 10% of the aggregate issue price of the
Outstanding STRYPES of that series, as provided in the Indenture; (f) certain
events in bankruptcy, insolvency or reorganization of the Company; and (g) any
other Event of Default provided with respect to STRYPES of that series.

  If an Event of Default (other than an Event of Default described in clause (f)
of the immediately preceding paragraph) with respect to the STRYPES of any
series shall occur and be continuing, either the Trustee or the holders of at
least 25% of the aggregate issue price of the Outstanding STRYPES of that series
by notice as provided in the Indenture may declare an amount equal to the
aggregate issue price of all the STRYPES of that series and the interest accrued
thereon and Additional Amounts payable in respect thereof, if any, to be
immediately due and payable in cash. If an Event of Default described in said
clause (f) shall occur, an amount equal to the aggregate issue price of all the
STRYPES of that series and the interest accrued thereon and Additional Amounts
payable in respect thereof, if any, will become immediately due and payable in
cash without any declaration or other action on the part of the Trustee or any
holder. After such acceleration, but before a judgment or decree based on
acceleration, the holders of a majority of the aggregate issue price of the
Outstanding STRYPES of that series may, under certain circumstances, rescind and
annul such acceleration if all Events of Default, other than the non-payment of
the amount equal to the aggregate issue price of all the STRYPES of that series
due by reason of such acceleration, have been cured or waived as provided in the
Indenture. See "Modification and Waiver" below.

  Subject to the provisions of the Indenture relating to the duties of the
Trustee, in case an Event of Default shall occur and be continuing, the Trustee
will be under no obligation to exercise any of its rights or powers under the
Indenture at the request or direction of any of the holders of STRYPES of any
series, unless such holders of that series shall have offered to the Trustee
reasonable security or indemnity against the costs, expenses and liabilities
which might be incurred by it in compliance with such request or direction.
Subject to such provisions for the indemnification of the Trustee, the holders
of a majority of the aggregate issue price of the STRYPES of any series 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 STRYPES of that series.

  The Company will be required to furnish to the Trustee annually a statement by
certain of its officers as to whether or not the Company, to their knowledge, is
in default in the fulfillment of any of its obligations under the Indenture and,
if so, specifying all such known defaults.

                                       14
<PAGE>
 
  The STRYPES and other series of Senior Debt Securities issued under the
Indenture will not have the benefit of any cross-default provisions with other
indebtedness of the Company.

MODIFICATION AND WAIVER

  Unless otherwise specified in a Prospectus Supplement, modifications of and
amendments to the Indenture affecting a series of STRYPES may be made by the
Company and the Trustee with the consent of the holders of 66(SM)% of the 
aggregate issue price of the Outstanding STRYPES of such series; provided,
however, that no such modification or amendment may, without the consent of the
holder of each Outstanding STRYPES of such series affected thereby, (a) change
the Maturity Date or the Stated Maturity of any installment of interest or
Additional Amounts on any STRYPES or any premium payable on the redemption
thereof, or change the Redemption Price, (b) reduce the amount of Underlying
Securities payable with respect to any STRYPES (or reduce the amount of cash
payable in lieu thereof), (c) reduce the amount of interest or Additional
Amounts payable on any STRYPES or reduce the amount of cash payable with respect
to any STRYPES upon acceleration of the maturity thereof, (d) change the place
or currency of payment of interest or Additional Amounts on, or any amount of
cash payable with respect to, any STRYPES, (e) impair the right to institute
suit for the enforcement of any payment on or with respect to any STRYPES,
including the payment of Underlying Securities with respect to any STRYPES, (f)
reduce the percentage of the aggregate issue price of Outstanding STRYPES of
such series, the consent of whose holders is required to modify or amend the
Indenture, (g) reduce the percentage of the aggregate issue price of Outstanding
STRYPES of such series necessary for waiver of compliance with certain
provisions of the Indenture or for waiver of certain defaults or (h) modify such
provisions with respect to modification and waiver. Except as provided in the
Indenture, no modification of or amendment to the Indenture may adversely affect
the rights of a holder of any other Senior Debt Security without the consent of
such holder.

  The holders of a majority of the aggregate issue price of each series of
STRYPES may waive compliance by the Company with certain restrictive provisions
of the Indenture. The holders of a majority of the aggregate issue price of each
series of STRYPES may waive any past default under the Indenture, except a
default in the payment of the Underlying Securities with respect to any STRYPES
of that series, or of cash payable in lieu thereof, or in the payment of any
premium, interest or Additional Amounts on any STRYPES of that series for which
payment had not been subsequently made or in respect of a covenant and provision
of the Indenture which cannot be modified or amended without the consent of the
holder of each Outstanding STRYPES of such series affected.

GOVERNING LAW

  The Indenture and the STRYPES will be governed by, and construed in accordance
with, the laws of the State of New York.

LISTING

  The STRYPES have listed on the NYSE under the symbol "IGL."

                         CERTAIN ARRANGEMENTS WITH GVI

  Pursuant to an agreement (the "Purchase Agreement") among the Company, Merrill
Lynch Mortgage Capital Inc., a wholly-owned subsidiary of the Company (the
"ML&Co. Subsidiary"), and GVI, GVI is obligated to deliver to the ML&Co.
Subsidiary immediately prior to the Maturity Date the Reference Property
required by the Company to pay and discharge all of the STRYPES. In lieu of
delivering the Reference Property immediately prior to the Maturity Date, GVI
has the right to satisfy its obligation under the Purchase Agreement by
delivering at such time cash in an amount equal to the value of such Reference
Property immediately prior to the Maturity Date. Such right, if exercised by
GVI, must be exercised with respect to all of the Reference Property deliverable
pursuant to the Purchase Agreement. Under the Purchase Agreement, the Company
has agreed to pay and discharge the STRYPES by delivering to the holders thereof
on the Maturity Date the form of consideration that the ML&Co. Subsidiary

                                       15
<PAGE>
 
receives from GVI. The consideration to be paid by the ML&Co. Subsidiary under
the Purchase Agreement is $153,382,017 in the aggregate, which was paid to GVI
on July 9, 1996. No other consideration is payable by the ML&Co. Subsidiary to
GVI in connection with its acquisition of the Reference Property pursuant to the
Purchase Agreement or the performance of the Purchase Agreement by GVI. The
Company has agreed with GVI that, without the prior consent of GVI, it will not
amend the Indenture in any respect that would adversely affect any obligation of
GVI under the Purchase Agreement, including, without limitation, increasing the
consideration that GVI is obligated to deliver pursuant to the Purchase
Agreement.

  Until such time, if any, as GVI shall have delivered the Reference Property to
the ML&Co. Subsidiary pursuant to the terms of the Purchase Agreement, GVI will
retain all ownership rights with respect to the Reference Property held by it
(including, without limitation, voting rights and rights to receive any
dividends, interest or other distributions in respect thereof).

  GVI has no obligations with respect to the STRYPES or amounts to be paid to
holders thereof, including any obligation to take the needs of the Company or of
holders of the STRYPES into consideration in determining whether to deliver the
Reference Property or cash or for any other reason. The Purchase Agreement among
the Company, the ML&Co. Subsidiary and GVI is a commercial transaction and does
not create any rights in, or for the benefit of, any holder of STRYPES.

  In the event GVI does not perform under the Purchase Agreement, the Company
will be required to otherwise acquire the Reference Property for delivery to the
holders of the STRYPES on the Maturity Date, unless it elects to exercise its
option to deliver cash with an equal value.

ITEM 15. "INDEMNIFICATION OF DIRECTORS AND OFFICERS."
 
  Section 145 of the General Corporation Law of the State of Delaware, as
amended, provides that under certain circumstances a corporation may 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, by reason of the fact that such
person is or was a director, officer, employee or agent of the corporation or
is or was serving at its request in such capacity in another corporation or
business association, against expenses (including attorneys' fees), judgments,
fines and amounts paid in settlement actually and reasonably incurred by such
person in connection with such action, suit or proceeding if such person acted
in good faith and in a manner such person 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 such
person's conduct was unlawful.
 
  Article XIII, Section 2 of the Restated Certificate of Incorporation of the
Registrant provides in effect that, subject to certain limited exceptions, the
Registrant shall indemnify its directors and officers to the extent authorized
or permitted by the General Corporation Law of the State of Delaware.

indemnification of the Registrant, its controlling persons, its directors and
certain of its officers by the Underwriters against certain liabilities,
including liabilities under the Securities Act of 1933, as amended.
 
  The directors and officers of the Registrant are insured under policies of
insurance maintained by the Registrant, subject to the limits of the policies,
against certain losses arising from any claim made against them by reason of
being or having been such directors or officers. In addition, the Registrant
has entered into contracts with all of its directors providing for
indemnification of such persons by the Registrant to the full extent
authorized or permitted by law, subject to certain limited exceptions.

ITEM 17. UNDERTAKINGS
 
  The undersigned registrant hereby undertakes:
 
    (a)(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;
 
      (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;
 
                                     II-7
<PAGE>
 
  provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if
  the registration statement is on Form S-3 and the information required to
  be included in a post-effective amendment by those paragraphs is contained
  in periodic reports filed 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, 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 the 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.
 
    (b) 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 15(d) of the Securities Exchange Act of 1934 that is
  incorporated by reference in this 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 provisions referred
  to in Item 15 of this registration statement, 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
  such 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.
 
    (d) To file an application for the purpose of determining the eligibility
  of the trustee to act under subsection (a) of Section 310 of the Trust
  Indenture Act (the "Act") in accordance with the rules and regulations
  prescribed by the Commission under Section 305(b)(2) of the Act.

to receive from the Company a payment or delivery determined by reference to
decreases or increases in the level of an index or portfolio based on one or

hereinafter collectively referred to as the "Warrant Agreements".

     Based upon the foregoing and upon such further investigation as we deem
relevant in the premises, we are of the opinion:

     1.   The Company has been duly incorporated under the laws of the State of
Delaware.

     2.   The Senior Indentures and the Subordinated Indenture have each been
duly and validly authorized, executed and delivered by the Company and, as
amended by the Trust Indenture Reform Act of 1990, constitute valid and binding
agreements of the Company, enforceable in accordance with their respective
terms.

     3.   When appropriate corporate action has been taken to authorize the
Company to execute and deliver any applicable Index Warrant Indenture,
supplemental indenture or Warrant Agreement, to fix the terms of one or more
issues of Securities under an Indenture or Warrant Agreement and to authorize
their issue, and such Indenture or Warrant Agreement shall have been duly
executed and delivered by the Company and the trustee or warrant agent, and when
the Securities with terms so fixed shall have been duly authenticated or
countersigned by the trustee or warrant agent, as the case may be, and duly
issued under the respective Indenture or Warrant Agreement in accordance with
such corporate action, such Indentures and/or Warrant Agreements and such
Securities will constitute valid and binding agreements of the Company,
enforceable in accordance with their terms.

     With respect to enforcement, the above opinions are qualified to the extent
that enforcement of the Indentures, Warrant Agreements or Securities may be
limited by bankruptcy, insolvency or other laws of general applicability
relating to or affecting enforcement of creditors' rights or by general equity
principles, and further to the extent that enforcement of any Securities
denominated in other than United States dollars may be limited by requirements
that a claim (or foreign currency judgment in respect of such claim) be
converted into United States dollars at a rate of exchange prevailing on a date
determined pursuant to applicable law.  We have further assumed with respect to
enforcement that, when fixed, the terms of the Securities will comply with all
appli-

cable "bucket shop" or similar state laws, or have the availability of federal
preemption therefrom.

     We consent to the filing of this opinion as an exhibit to the Registration
Statement and to the use of our name wherever appearing in the Registration
Statement and any amendment thereto.

                                    Very truly yours,

consolidated earnings, changes in consolidated stockholders' equity and 
consolidated cash flows for the years ended December 31, 1993 and December 25, 
1992 (none of which are presented or incorporated by reference herein); and we 
expressed unqualified opinions on those consolidated financial statements. In 
our opinion, the information set forth in the table under the caption Ratio of 
Earnings to Fixed Charges for each of the five years in the period ended 
December 27, 1996 appearing on page 4 of the prospectuses relating to Debt
Securities and Warrants and STRYPES, and on page S-3 of the prospectus relating
to Medium-Term Notes, Series B, all of which are a part of this Registration
Statement of the Company on Form S-3, is fairly stated in all material respects
in relation to the consolidated financial statements from which it has been
derived.
