    The 7% Trust Originated Preferred Securities-SM- (the "TOPrS-SM-" or "Trust
Preferred Securities") offered hereby represent preferred undivided beneficial
ownership interests in the assets of Merrill Lynch Preferred Capital Trust III,
a statutory business trust formed under the laws of the State of Delaware (the
"Trust"). Merrill Lynch & Co., Inc., a Delaware corporation (the "Company" or
"Merrill Lynch"), will own all the common securities (the "Trust Common
Securities" and, together with the Trust Preferred Securities, the "Trust
Securities") representing undivided beneficial ownership interests in the assets
of the Trust. The Trust exists for the sole purpose of issuing the Trust
Securities and investing the proceeds as described below and engaging in
activities incident thereto. The proceeds from the sale of the Trust Securities
will be used by the Trust to purchase Partnership Preferred Securities
("Partnership Preferred Securities"), representing the limited partner interests
of Merrill Lynch Preferred Funding III, L.P., a Delaware limited partnership
(the "Partnership"). The general partner interest, which constitutes all of the
interest in the Partnership other than the limited partner interests represented
by the Partnership Preferred Securities, is owned by the Company, which is the
sole general partner of the Partnership (in such capacity, the "General
Partner"). Substantially all of the proceeds from the sale of the Partnership
Preferred Securities, together with the capital contribution from the General
Partner, will be used by the Partnership to purchase Debentures (as defined
herein), which consist of debt instruments of the Company and one or more of its
eligible controlled affiliates. In addition, approximately one percent of the
proceeds from the sale of the Partnership Preferred Securities and the capital
contribution from the General Partner will be used to purchase Eligible Debt
Securities (as defined herein). See "Description of the Partnership Preferred
Securities -- Partnership Investments".

SECURITIES, INCLUDING CERTAIN UNITED STATES FEDERAL INCOME TAX CONSEQUENCES.
 
    Application will be made to list the Trust Preferred Securities on the New
York Stock Exchange, Inc. (the "New York Stock Exchange"). If approved for
listing, trading of the Trust Preferred Securities on the New York Stock
Exchange is expected to commence within the 30-day period after the initial
delivery of the Trust Preferred Securities. See "Underwriting".

    its subsidiaries, the Company has agreed to pay to the Underwriters as

    Security (or $23,625,000 in the aggregate); provided that such compensation
    for sales of more than 10,000 Trust Preferred Securities to a single
    purchaser will be $.50 per Trust Preferred Security. Therefore, to the
    extent of such sales, the actual amount of Underwriters' Compensation will
    be less than the aggregate amount specified in the preceding sentence. See
    "Underwriting".

    The Trust Preferred Securities offered hereby are offered severally by the
Underwriters, as specified herein, subject to receipt and acceptance by them and
subject to their right to reject any order in whole or in part. It is expected
that delivery of the Trust Preferred Securities will be made only in book-entry
form through the facilities of The Depository Trust Company ("DTC") on or about
January 16, 1998.

(CONTINUED FROM COVER PAGE)
 
    Holders of the Trust Preferred Securities will be entitled to receive
cumulative cash distributions accumulating from the date of original issuance
and payable quarterly in arrears on each March 30, June 30, September 30 and
December 30, commencing March 30, 1998, at an annual rate of 7% of the
liquidation amount of $25 per Trust Preferred Security (equivalent to $1.75 per
Trust Preferred Security per annum), if, as and when the Trust has funds
available for payment. See "Description of the Trust Preferred Securities --
Distributions." Distributions not paid on the scheduled payment date will
accumulate and compound quarterly at a rate per annum equal to 7%. The
distribution rate and the distribution payment dates and other payment dates for
the Trust Preferred Securities will correspond to the distribution rate and
distribution payment dates and other payment dates for the Partnership Preferred
Securities, which are the sole assets of the Trust. As described above, the
assets of the Partnership will initially consist only of the Debentures and, to
a limited extent, Eligible Debt Securities.
 
    The payment of distributions by the Trust and payments on liquidation of the
Trust or the redemption of Trust Preferred Securities, as described below, are
guaranteed on a subordinated basis by the Company (the "Trust Guarantee") to the
extent the Trust has funds available therefor as described under "Description of
the Trust Guarantee". The payment of distributions by the Partnership (if, as
and when declared) on the Partnership Preferred Securities and payments on
liquidation of the Partnership or the redemption of Partnership Preferred
Securities, as described below, are also guaranteed on a subordinated basis by
the Company (the "Partnership Guarantee") to the extent the Partnership has
funds available therefor as described under "Description of the Partnership
Guarantee". In addition, payments in respect of the Debentures (other than the
Company Debenture (as defined herein)) will be fully and unconditionally
guaranteed, on a subordinated basis, by the Company (the "Investment
Guarantees") for the benefit of the holders of the Partnership Preferred
Securities. The Trust Guarantee, the Partnership Guarantee and the Investment
Guarantees (collectively, the "Guarantees"), when taken together with the
Company Debenture and the Company's obligations to pay all fees and expenses of
the Trust and the Partnership, constitute a guarantee to the extent set forth
herein by the Company of the distribution, redemption and liquidation payments
payable to the holders of the Trust Preferred Securities. The Guarantees do not
apply to current distributions by the Partnership unless and until such
distributions are declared by the Partnership out of funds legally available for
payment or to liquidating distributions unless there are assets available for
payment in the Partnership, each as more fully described in the next succeeding
paragraph and under "Risk Factors -- Insufficient Income or Assets Available to
Partnership". The Company's obligations under the Guarantees are subordinate and
junior in right of payment to all other liabilities of the Company and rank PARI
PASSU with the most senior preferred stock issued from time to time by the
Company, with similar guarantees issued by the Company in connection with the
$275,000,000 aggregate liquidation amount of 7 3/4% Trust Originated Preferred
Securities issued by Merrill Lynch Preferred Capital Trust I and the
$300,000,000 aggregate liquidation amount of 8% Trust Originated Preferred
Securities issued by Merrill Lynch Preferred Capital Trust II, and with any
guarantee now or hereafter entered into by the Company in respect of any
preferred stock of any other Finance Subsidiary (as defined below). The
Company's obligations under the Company Debenture are subordinate and junior in
right of payment to all Senior Indebtedness of the Company. At September 26,
1997, the Company had outstanding Senior Indebtedness aggregating approximately
$77.4 billion, which would have ranked senior to the Company's obligations under
the Guarantees and the Company Debenture. See "Risk Factors -- Ranking of
Subordinate Obligations Under the Guarantees and the Company Debenture". The
term "Senior Indebtedness" means 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 the Company Debenture, as the case may
be.
 
    Distributions on the Partnership Preferred Securities will be declared and
paid only as determined in the sole discretion of the Company in its capacity as
the General Partner of the Partnership. In addition, the General Partner is not
obligated to declare distributions on the Partnership Preferred Securities at
any time, including upon or following a Partnership Enforcement Event (as
defined herein). To the extent that
 
                                       2
<PAGE>
the issuers (including, where applicable, the Company, as guarantor) of the
securities in which the Partnership invests defer or fail to make any payments
in respect of such securities (or, if applicable, guarantees), the Partnership
will not have sufficient funds to pay and will not declare or pay distributions
on the Partnership Preferred Securities. In addition, as described under "Risk
Factors -- Insufficient Income or Assets Available to Partnership", the
Partnership may not have sufficient funds to pay current or liquidating
distributions on the Partnership Preferred Securities if (i) at any time that
the Partnership is receiving current payments in respect of the securities held
by the Partnership (including the Debentures), the General Partner, in its sole
discretion, does not declare distributions on the Partnership Preferred
Securities and the Partnership receives insufficient amounts to pay the
additional compounded distributions that will accumulate in respect of the
Partnership Preferred Securities, (ii) the Partnership reinvests the proceeds
received in respect of the Debentures upon their retirement or at their
maturities in Affiliate Investment Instruments (as defined herein) and Eligible
Debt Securities that do not generate income in an amount that is sufficient to
pay full distributions in respect of the Partnership Preferred Securities or
(iii) the Partnership invests in debt securities of Investment Affiliates that
are not guaranteed by the Company and that cannot be liquidated by the
Partnership for an amount sufficient to pay such distributions in full. The
Debentures will provide that payments of interest may be deferred at any time,
and from time to time, by the relevant issuer for a period not exceeding six
consecutive quarters. If an issuer were to so defer the payment of interest,
interest would continue to accrue and compound at the stated interest rate on
such Debenture. If the Partnership does not declare and pay distributions on the
Partnership Preferred Securities out of funds legally available for
distribution, the Trust will not have sufficient funds to make distributions on
the Trust Preferred Securities, in which event the Trust Guarantee will not
apply to such distributions until the Trust has sufficient funds available
therefor. See "Risk Factors -- Distributions Payable Only if Declared by General
Partner; Restrictions on Certain Payments; Tax Consequences", "-- Insufficient
Income or Assets Available to Partnership", "Description of the Trust Preferred
Securities -- Distributions" and "Description of the Partnership Preferred
Securities -- Distributions".
 
    The Partnership may, from time to time and subject to the restrictions
described herein, reinvest payments received with respect to the Affiliate
Investment Instruments (including the Debentures) and the Eligible Debt
Securities, in additional Affiliate Investment Instruments and Eligible Debt
Securities. As of the date of this Prospectus, the Company, as the General
Partner, does not intend to cause the Partnership to reinvest regularly
scheduled periodic payments of interest or dividends received by the Partnership
in the manner described herein, although there can be no assurance that the
General Partner's intention in respect of such reinvestments will not change in
the future.
 
    If (a) for any distribution period, full distributions on a cumulative basis
on any Trust Preferred Securities have not been paid or set apart for payment,
(b) an Investment Event of Default by any Investment Affiliate in respect of any
Affiliate Investment Instrument has occurred and is continuing or (c) the
Company is in default of its obligations under any Guarantee, then during such
period (i) the Company shall not declare or pay dividends on, make distributions
with respect to, or redeem, purchase or acquire, or make a liquidation payment
with respect to, any of its capital stock or comparable equity interest (except
for (x) dividends or distributions in shares of, or options, warrants or rights
to subscribe for or purchase shares of, its capital stock, and conversions or
exchanges of common stock of one class into common stock of another class, (y)
redemptions or purchases of any rights pursuant to the Amended and Restated
Rights Agreement dated as of December 2, 1997 between the Company and The Chase
Manhattan Bank (successor by merger to Manufacturers Hanover Trust Company), or
any successor to such Rights Agreement (the "Rights Agreement") and the issuance
of preferred stock pursuant to such rights and (z) purchases or acquisitions by
the Company or its affiliates in connection with transactions effected by or for
the account of customers of the Company or any of its subsidiaries or in
connection with the distribution or trading of such capital stock or comparable
equity interest) and (ii) the Company shall not make, permit any Finance
Subsidiary to make, or make any payments that would enable any Finance
Subsidiary to make, any payment of any dividends on, any distribution with
respect to, or any redemption,
 
                                       3
<PAGE>
purchase or other acquisition of, or any liquidation payment with respect to,
any preferred security or comparable equity interest of any Finance Subsidiary.
"Finance Subsidiary" means Merrill Lynch Preferred Capital Trust I, Merrill
Lynch Preferred Capital Trust II and any other wholly-owned subsidiary of the
Company the principal purpose of which is to raise capital for the Company by
issuing securities that are guaranteed by the Company and the proceeds of which
are loaned to or invested in the Company or one or more of its affiliates.
 
    The Partnership Preferred Securities are redeemable by the Partnership, in
whole or in part, from time to time, on or after March 30, 2008 at an amount per
Partnership Preferred Security equal to $25 plus accumulated and unpaid
distributions thereon to the date fixed for redemption. The Partnership
Preferred Securities may also be redeemed, in whole but not in part, at any time
upon the occurrence of a Partnership Special Event (as defined herein). If the
Partnership redeems the Partnership Preferred Securities, the Trust must redeem
Trust Securities on a PRO RATA basis having an aggregate liquidation amount
equal to the aggregate liquidation preference of the Partnership Preferred
Securities so redeemed at a redemption price of $25 per Partnership Preferred
Security plus all accumulated and unpaid distributions thereon to the date fixed
for redemption (the "Redemption Price"). See "Description of the Trust Preferred
Securities -- Mandatory Redemption". Neither the Partnership Preferred
Securities nor the Trust Preferred Securities have any scheduled maturity or are
redeemable at any time at the option of the holders thereof.
 
    The Trust will be dissolved upon the occurrence of a Trust Special Event (as
defined herein). Upon dissolution of the Trust, the Partnership Preferred
Securities will be distributed to the holders of the Trust Securities, on a PRO
RATA basis, in lieu of any cash distribution, unless the Partnership Preferred
Securities are redeemed in the limited circumstances described herein. If the
Partnership Preferred Securities are distributed to the holders of the Trust
Securities, the Company will use its best efforts to cause the Partnership
Preferred Securities to be listed on the New York Stock Exchange or such other
national securities exchange or similar organization as the Trust Preferred
Securities are then listed or quoted. See "Description of the Trust Preferred
Securities -- Trust Special Event Redemption or Distribution" and "Description
of the Partnership Preferred Securities".
 
    In the event of any liquidation, dissolution, winding up or termination of
the Trust, the holders of the Trust Preferred Securities will be entitled to
receive for each Trust Preferred Security a liquidation amount of $25 plus
accumulated and unpaid distributions thereon, except to the extent, in
connection with such dissolution, Partnership Preferred Securities are
distributed to the holders of the Trust Preferred Securities. Upon (i) the
occurrence of an Investment Event of Default by an Investment Affiliate in
respect of any Affiliate Investment Instrument or (ii) default by the Company on
any of its obligations under any Guarantee, the holders of the Trust Preferred
Securities will have a preference over the holders of the Trust Common
Securities with respect to payments upon liquidation of the Trust. Under no
circumstances will the investment instruments held by the Partnership be
distributed in kind to the holders of the Trust Preferred Securities or
Partnership Preferred Securities. See "Description of the Trust Preferred
Securities -- Liquidation Distribution Upon Dissolution".
 
    Certain persons participating in this offering may engage in transactions
that stabilize, maintain or otherwise affect the price of the Trust Preferred
Securities. Such transactions may include stabilizing, the purchase of Trust
Preferred Securities to cover syndicate short positions and the imposition of
penalty bids. For a description of these activities, see "Underwriting".

                               payment. Distributions will be payable quarterly in arrears
                               on each March 30, June 30, September 30 and December 30,
                               commencing March 30, 1998. Distributions not made on the
                               scheduled payment date will accumulate and compound
                               quarterly at a rate per annum equal to 7%. The distributions
                               payable with respect to March 30, 1998 will represent
                               distributions accumulated from January 16, 1998 and will
                               equal $.36 for each $25 Trust Preferred Security.
 
                               The ability of the Trust to pay distributions on the Trust
                               Preferred Securities is entirely dependent on its receipt of
                               corresponding distributions with respect to the Partnership
                               Preferred Securities. The ability of the Partnership to pay
                               distributions on the Partnership Preferred Securities is, in
                               turn, dependent on its receipt of payments with respect to
                               the Debentures and the Eligible Debt Securities held by the
                               Partnership. The Debentures will provide that payments of
                               interest may be deferred at any time, and from time to time,
                               by the relevant issuer for a period not exceeding six
                               consecutive quarters. Distributions on the Partnership
                               Preferred Securities will be declared and paid only as
                               determined in the sole discretion of the Company in its
                               capacity as the General Partner of the Partnership. See
                               "Risk Factors -- Distributions Payable Only if Declared by
                               General Partner; Restrictions on Certain Payments; Tax

                               Guarantee, respectively, shall have the right to enforce
                               such Guarantees, including the right to enforce the covenant
                               restricting certain payments by the Company and Finance
                               Subsidiaries described below.
 
                               Under no circumstances, however, shall the Special
                               Representative have authority to cause the General Partner
                               to declare distributions on the Partnership Preferred
                               Securities. If the Partnership does not declare and pay
                               distributions on the Partnership Preferred Securities out of
                               funds legally available for distribution, the Trust will not
                               have sufficient funds to make distributions on the Trust
                               Preferred Securities. See "Risk Factors -- Insufficient

                               Trust Preferred Securities have not been paid or set apart
                               for payment, (b) an Investment Event of Default by any

Liquidation Amount...........  In the event of any liquidation of the Trust, holders will
                               be entitled to receive $25 per Trust Preferred Security plus
                               an amount equal to any accumulated and unpaid distributions
                               thereon to the date of payment (such amount being the "Trust
                               Liquidation Distribution"), unless Partnership Preferred
                               Securities are distributed to such holders in connection
                               with a Trust Special Event. If upon a liquidation of the
                               Trust (in which the Partnership Preferred Securities are not
                               distributed to holders of the Trust Securities), the Trust
                               Liquidation Distribution can be paid only in part because
                               the Trust has insufficient assets available to pay in full
                               the aggregate Trust Liquidation Distribution, then the
                               amounts payable directly by the Trust on the Trust Preferred
                               Securities shall be paid on a PRO RATA basis. The holders of
                               the Trust Common Securities will be entitled to receive
                               distributions upon any such liquidation PRO RATA with the
                               holders of the Trust Preferred Securities, except that upon
                               (i) the occurrence of an Investment Event of Default by an
                               Investment Affiliate (including the Company) in respect of
                               any Affiliate Investment Instrument or (ii) default by the
                               Company on any of its obligations under any Guarantee, the
                               holders of the Trust Preferred Securities will have a
                               preference over the holders of the Trust Common Securities
                               with respect to payments upon liquidation of the Trust. See
                               "Description of the Trust Preferred Securities --
                               Liquidation Distribution Upon Dissolution".
 
Optional Redemption..........  The Partnership Preferred Securities will be redeemable for
                               cash, at the option of the Partnership, in whole or in part,
                               from time to time, after March 30, 2008 at an amount per
                               Partnership Preferred Security equal to $25 plus accumulated
                               and unpaid distributions thereon. Upon any redemption of the
                               Partnership Preferred Securities, the Trust Preferred
                               Securities will be redeemed, in whole or in part, as
                               applicable, at the Redemption Price. See "Description of the
                               Partnership Preferred Securities--Optional Redemption" and
                               "Description of the Trust Preferred Securities -- Mandatory
                               Redemption". Neither the Partnership Preferred Securities
                               nor the Trust Preferred Securities have any scheduled
                               maturity or are redeemable at any time at the option of the
                               holders thereof.
 
Guarantees...................  The Company will irrevocably guarantee, on a subordinated
                               basis, the payment in full of (i) any accumulated and unpaid
                               distributions on the Trust Preferred Securities to the
                               extent of funds of the Trust legally available therefor,

                               Preferred Securities to the extent of funds of the Trust
                               legally available therefor and (iii) generally, the
                               liquidation amount of the Trust Preferred Securities to the

                               distribution to holders of Trust Preferred Securities. See
                               "Description of the Trust Guarantee".
 
                               The Company will also irrevocably guarantee, on a
                               subordinated basis and to the extent set forth herein, the

                               the Partnership Preferred Securities to the extent of the
                               assets of the Partnership legally available for distribution
                               to holders of Partnership Preferred Securities. See
                               "Description of the Partnership Guarantee".
 
                               The Company will fully and unconditionally guarantee, on a
                               subordinated basis, payments in respect of the Debentures
                               (other than the Company Debenture) for the benefit of the
                               holders of the Partnership Preferred Securities, to the
                               extent described under "Description of the Partnership
                               Preferred Securities -- Investment Guarantees". The
                               Guarantees, when taken together with the Company Debenture
                               and the Company's obligations to pay all fees and expenses
                               of the Trust and the Partnership, constitute a guarantee to
                               the extent set forth herein by the Company of the
                               distribution, redemption and liquidation amounts payable to
                               the holders of the Trust Preferred Securities. The
                               Guarantees do not apply, however, to current distributions
                               by the Partnership unless and until such distributions are
                               declared by the Partnership out of funds legally available
                               for payment or to liquidating distributions unless there are
                               assets available for payment in the Partnership, each as

                               Income or Assets Available to Partnership". The Company's
                               obligations under the Guarantees are subordinate and junior
                               in right of payment to all other liabilities of the Company

Voting Rights................  Generally, holders of the Trust Preferred Securities will
                               not have any voting rights. The holders of a majority in

                               however, have the right to direct the time, method and place
                               of conducting any proceeding for any remedy available to the
                               Property Trustee, or direct the exercise of any trust or
                               power conferred upon the Property Trustee under the
                               Declaration, including the right to direct the Property
                               Trustee, as holder of the Partnership Preferred Securities,
                               (i) to exercise its rights in the manner described above

Special Event Redemptions or
  Distributions..............  Upon the occurrence of a Trust Tax Event (which event will
                               generally be triggered upon the occurrence of certain
                               adverse tax consequences or the denial of an interest
                               deduction on the Debentures held by the Partnership) or a
                               Trust Investment Company Event (which event will generally
                               be triggered if the Trust is considered an "investment com-
                               pany" under the Investment Company Act of 1940, as amended
                               (the "1940 Act")), except in certain limited circumstances,
                               the Regular Trustees (as defined herein) will have the right
                               to liquidate the Trust and cause Partnership Preferred
                               Securities to be distributed to the holders of the Trust
                               Preferred Securities. In certain circumstances involving a
                               Partnership Tax Event (which event will generally be
                               triggered upon the occurrence of certain adverse tax

                               Investment Company Event (which event will generally be
                               triggered if the Partnership is considered an "investment
                               company" under the 1940 Act), the Partnership will have the
                               right to redeem the Partnership Preferred Securities, in
                               whole (but not in part), at $25 per Partnership Preferred
                               Security plus accumulated and unpaid distributions thereon,
                               regardless of the occurrence of any Trust Tax Event or Trust

                               therewith, in which event the Trust Securities will be
                               redeemed at the Redemption Price. See "Description of the
                               Trust Preferred Securities -- Trust Special Event Redemption

Form of Trust Preferred
  Securities.................  The Trust Preferred Securities will be represented by a
                               global certificate or certificates registered in the name of
                               Cede & Co., as nominee for DTC. Beneficial interests in the
                               Trust Preferred Securities will be evidenced by, and
                               transfers thereof will be effected only through, records
                               maintained by the participants in DTC. Except as described
                               herein, Trust Preferred Securities in certificated form will
                               not be issued in exchange for the global certificate or
                               certificates. See "Description of the Trust Preferred

Use of Proceeds..............  All of the proceeds from the sale of the Trust Securities
                               will be invested by the Trust in the Partnership Preferred
                               Securities. The Partnership will use the funds to make
                               investments in Debentures and certain Eligible Debt
                               Securities. The Company and the subsidiaries of the Company
                               which are the issuers of the Debentures will use the
                               proceeds from the sale of such Debentures primarily to fund
                               the proposed acquisition of Mercury Asset Management Group
                               plc, for other general corporate purposes, and to repay
                               certain intercompany indebtedness. See "Use of Proceeds".

                                  RISK FACTORS
 
    PROSPECTIVE PURCHASERS OF THE TRUST PREFERRED SECURITIES SHOULD CONSIDER
CAREFULLY THE RISK FACTORS SET FORTH BELOW, AS WELL AS ALL OTHER INFORMATION
CONTAINED OR INCORPORATED BY REFERENCE IN THIS PROSPECTUS, IN EVALUATING AN
INVESTMENT IN THE TRUST PREFERRED SECURITIES.
 
DISTRIBUTIONS PAYABLE ONLY IF DECLARED BY GENERAL PARTNER; RESTRICTIONS ON
  CERTAIN PAYMENTS; TAX CONSEQUENCES
 
    Distributions on the Partnership Preferred Securities will be payable only
if, as and when declared by the General Partner in its sole discretion. The
Company is the sole General Partner of the Partnership, and the Debentures will
constitute obligations of the Company and its affiliates. If interest payments
on the Debentures are deferred as permitted thereby, or if such interest
payments are not paid to the Partnership according to their terms (and guarantee
payments on the Investment Guarantees are not made by the Company), the
Partnership will generally lack funds to pay distributions on the Partnership
Preferred Securities. If the Partnership does not make current distributions on
the Partnership Preferred Securities, either because the General Partner does
not declare distributions to be made or because the Partnership lacks sufficient
funds, the Trust will not have funds available to make current distributions on
the Trust Preferred Securities. As described under "Description of the Trust
Guarantee -- Covenants of the Company", in certain circumstances, the Company
will be restricted from, among other things, paying any dividends on its Common
Stock.
 
    Should the Partnership fail to pay current distributions on the Partnership
Preferred Securities, each holder of Trust Preferred Securities will generally
be required to accrue income, for United States federal income tax purposes, in
respect of the cumulative deferred distributions (including interest thereon)
allocable to its proportionate share of the Partnership Preferred Securities. As
a result, each holder of Trust Preferred Securities will recognize income for
United States federal income tax purposes in advance of the receipt of cash and
will not receive the cash from the Trust related to such income if such holder
disposes of its Trust Preferred Securities prior to the record date for the date
on which distributions of such amounts are made by the Trust. See "Certain
Federal Income Tax Considerations".
 
INSUFFICIENT INCOME OR ASSETS AVAILABLE TO PARTNERSHIP
 
    The Trust Preferred Securities are subject to the risk of a current or
liquidating distribution rate mismatch between the rate paid on the Trust
Preferred Securities and the rate paid on the securities held by the
Partnership, including the Debentures and any additional securities acquired by
the Partnership in the future. Such mismatch could occur if (i) at any time that
the Partnership is receiving current payments in respect of the securities held
by the Partnership (including the Debentures), the General Partner, in its sole
discretion, does not declare distributions on the Partnership Preferred
Securities and the Partnership receives insufficient amounts to pay the
additional compounded distributions that will accumulate in respect of the
Partnership Preferred Securities, (ii) the Partnership reinvests the proceeds
received in respect of the Debentures upon their retirement or at their
maturities in Affiliate Investment Instruments or Eligible Debt Securities that
do not generate income in an amount that is sufficient to pay full distributions
in respect of the Partnership Preferred Securities at a rate of 7% per annum or
(iii) the Partnership invests in debt securities of Investment Affiliates that
are not guaranteed by the Company and that cannot be liquidated by the
Partnership for an amount sufficient to pay such distributions in full. If the
reinvestments in the securities of the Investment Affiliates contemplated by the
General Partner do not meet the eligibility criteria for Affiliate Investment
Instruments described under "Description of the Partnership Preferred Securities
- -- Partnership Investments," the Partnership shall invest funds available for
reinvestment in Eligible Debt Securities. To the extent that the Partnership
lacks sufficient funds to make current or liquidating distributions on the
Partnership Preferred Securities in full, the Trust will not
 
                                       11
<PAGE>
have sufficient funds available to pay full current or liquidating distributions
on the Trust Preferred Securities.
 
DEPENDENCE ON AFFILIATE INVESTMENT INSTRUMENTS
 
    Approximately 99% of the proceeds from the issuance of the Partnership
Preferred Securities and the General Partner's capital contribution will be
invested in Debentures, which consist of debt instruments of the Company and one
or more eligible controlled affiliates. See "Description of the Partnership
Preferred Securities -- Partnership Investments".
 
SPECIAL EVENT REDEMPTION OR DISTRIBUTION
 
    Upon the occurrence of a Trust Special Event or a Partnership Special Event
(each of which will generally be triggered either upon (i) the occurrence of
certain adverse tax consequences to the Trust or the Partnership, as the case
may be, or the denial of an interest deduction by the related Investment
Affiliate on the Debentures held by the Partnership or (ii) the Trust or
Partnership being considered an "investment company" under the 1940 Act) (each,
a "Special Event"), the Trust will be dissolved with the result that, except in
the limited circumstances described below, the Partnership Preferred Securities
would be distributed to the holders of the Trust Securities in connection with
the liquidation of the Trust. In certain circumstances, the Partnership shall
have the right to redeem the Partnership Preferred Securities, in whole (but not
in part), in lieu of a distribution of the Partnership Preferred Securities by
the Trust, in which event the Trust will redeem the Trust Preferred Securities
for cash. See "Description of the Trust Preferred Securities -- Trust Special
Event Redemption or Distribution" and "Description of the Partnership Preferred
Securities -- Partnership Special Event Redemption".
 
    Unless the liquidation of the Trust occurs as a result of the Trust being
subject to United States federal income tax with respect to income on the
Partnership Preferred Securities, a distribution of the Partnership Preferred
Securities upon the dissolution of the Trust would not be a taxable event to
holders of the Trust Preferred Securities. If, however, the liquidation of the
Trust were to occur because the Trust is subject to United States federal income
tax with respect to income accrued or received on the Partnership Preferred
Securities, the distribution of Partnership Preferred Securities to holders by
the Trust would likely be a taxable event to each such holder, and a holder
would recognize gain or loss as if the holder had exchanged its Trust Preferred
Securities for the Partnership Preferred Securities it received upon the
liquidation of the Trust. Similarly, the holders of the Trust Preferred
Securities would recognize gain or loss if the Trust dissolves upon an
occurrence of a Partnership Special Event and the holders of Trust Preferred
Securities receive cash in exchange for their Trust Preferred Securities. See
"Certain Federal Income Tax Considerations -- Redemption of Trust Preferred
Securities for Cash".
 
    There can be no assurance as to the market prices for the Partnership
Preferred Securities that may be distributed in exchange for Trust Preferred
Securities if a dissolution or liquidation of the Trust were to occur.
Accordingly, the Partnership Preferred Securities that a holder of Trust
Preferred Securities may receive upon dissolution and liquidation of the Trust
may trade at a discount to the price that the investor paid to purchase the
Trust Preferred Securities offered hereby. Because holders of Trust Preferred
Securities may receive Partnership Preferred Securities upon the occurrence of a
Special Event, prospective purchasers of Trust Preferred Securities also are
making an investment decision with regard to the Partnership Preferred
Securities and should carefully review all the information regarding the
Partnership Preferred Securities contained herein. See "Description of the
Partnership Preferred Securities -- Partnership Special Event Redemption" and
"-- General".
 
RANKING OF SUBORDINATED OBLIGATIONS UNDER THE GUARANTEES AND THE COMPANY
  DEBENTURE
 
    The Company's obligations under the Trust Guarantee, the Partnership
Guarantee and the Investment Guarantees are subordinate and junior in right of
payment to all liabilities of the Company and will
 
                                       12
<PAGE>
rank PARI PASSU with the most senior preferred stock, if any, issued from time
to time by the Company, with similar guarantees issued by the Company in
connection with the $275,000,000 aggregate liquidation amount of 7 3/4% Trust
Originated Preferred Securities issued by Merrill Lynch Preferred Capital Trust
I and the $300,000,000 aggregate liquidation amount of 8% Trust Originated
Preferred Securities issued by Merrill Lynch Preferred Capital Trust II, and
with any guarantee now or hereafter entered into by the Company in respect of
any preferred stock of any other Finance Subsidiary, and the Company's
obligations under the Company Debenture are subordinate and junior in right of
payment to all Senior Indebtedness. At September 26, 1997, the Company had
outstanding Senior Indebtedness aggregating approximately $77.4 billion which
would have ranked senior to the Company's obligations under the Guarantees and
the Company Debenture. There are no terms in the Trust Preferred Securities, the
Partnership Preferred Securities, the Guarantees or the Debentures that limit
the Company's ability to incur additional indebtedness, including indebtedness
that ranks senior to the Guarantees. See "Description of the Partnership
Preferred Securities -- Partnership Investments" and "-- Investment Guarantees",
"Description of the Trust Guarantee" and "Description of the Partnership
Guarantee".
 
ENFORCEMENT OF CERTAIN RIGHTS BY OR ON BEHALF OF HOLDERS OF TRUST PREFERRED
  SECURITIES
 
    If a Trust Enforcement Event occurs and is continuing, then (a) the holders
of Trust Preferred Securities would rely on the enforcement by the Property
Trustee of its rights, as a holder of the Partnership Preferred Securities,
against the Company, including the right to direct the Special Representative to
enforce (i) the Partnership's creditors' rights and other rights with respect to
the Affiliate Investment Instruments and the Investment Guarantees, (ii) the
rights of the holders of the Partnership Preferred Securities under the
Partnership Guarantee, and (iii) the rights of the holders of the Partnership
Preferred Securities to receive distributions (only if and to the extent
declared out of funds legally available therefor) on the Partnership Preferred
Securities, and (b) the Trust Guarantee Trustee shall have the right to enforce
the terms of the Trust Guarantee, including the right to enforce the covenant
restricting certain payments by the Company and Finance Subsidiaries. Under no
circumstances, however, shall the Special Representative have authority to cause
the General Partner to declare distributions on the Partnership Preferred
Securities. As a result, although the Special Representative may be able to
enforce the Partnership's creditors' rights to accelerate and receive payments
in respect of the Affiliate Investment Instruments and the Investment
Guarantees, the Partnership would be entitled to reinvest such payments in
additional Affiliate Investment Instruments, subject to satisfying the
reinvestment criteria described under "Description of the Partnership Preferred
Securities -- Partnership Investments", and the Eligible Debt Securities, rather
than declaring and making distributions on the Partnership Preferred Securities.
See "Description of the Trust Preferred Securities -- Trust Enforcement Events".
 
LIMITED VOTING RIGHTS
 
    Holders of the Trust Preferred Securities will have limited voting rights
and will not be entitled to vote to appoint, remove or replace, or to increase
or decrease the number of, Trustees, which voting rights are vested exclusively
in the holder of the Trust Common Securities. See "Description of the Trust
Preferred Securities -- Voting Rights".
 
TRADING CHARACTERISTICS OF TRUST PREFERRED SECURITIES
 
    The price at which the Trust Preferred Securities may trade may not fully
reflect the value of the accumulated but unpaid distributions on the Trust
Preferred Securities (which will equal the accumulated but unpaid distributions
on the Partnership Preferred Securities). In addition, as a result of the right
of the General Partner not to declare current distributions on the Partnership
Preferred Securities, the market price of the Trust Preferred Securities (which
represent undivided beneficial ownership interests in the Partnership Preferred
Securities) may be more volatile than other similar securities where there is no
such right to defer current distributions. A holder who disposes of its Trust
Preferred Securities will be required
 
                                       13
<PAGE>
to include for United States federal income tax purposes accumulated but unpaid
distributions on the Partnership Preferred Securities through the date of
disposition in income as ordinary income, and to add such amount to its adjusted
tax basis in its pro rata share of the Partnership Preferred Securities deemed
disposed of. To the extent the selling price is less than the holder's adjusted
tax basis (which will include all accumulated but unpaid distributions), a
holder will recognize a capital loss. Subject to certain limited exceptions,
capital losses cannot be applied to offset ordinary income for United States
federal income tax purposes. See "Certain Federal Income Tax Considerations".
 
NO PRIOR MARKET FOR THE TRUST PREFERRED SECURITIES
 
    The Trust Preferred Securities constitute a new issue of securities with no
established trading market. Application will be made to list the Trust Preferred
Securities on the New York Stock Exchange. There can be no assurance that an
active market for the Trust Preferred Securities will develop or be sustained in
the future on the New York Stock Exchange. Although the Underwriters have
indicated to the Company that they intend to make a market in the Trust
Preferred Securities, as permitted by applicable laws and regulations, they are
not obligated to do so and may discontinue any such market-making at any time
without notice. Accordingly, no assurance can be given as to the liquidity of,
or trading markets for, the Trust Preferred Securities.
 
    The Trust Preferred Securities will only be sold to those investors for whom
such Trust Preferred Securities are considered suitable in light of their
particular circumstances.

to purchase Partnership Preferred Securities, and will be applied by the
Partnership to invest in Debentures and Eligible Debt Securities. See
"Description of the Partnership Preferred Securities -- Partnership
Investments". The Company and the subsidiaries of the Company which are the
issuers of the Debentures will use the proceeds from the sale of such Debentures
to the Partnership of $750,000,000 primarily to fund the acquisition of Mercury
Asset Management Group plc described below under "Recent Developments", for
other general corporate purposes, and to repay certain intercompany
indebtedness. To the extent that Trust Preferred Securities being purchased for
resale by MLPF&S are not resold, the aggregate proceeds to the Company and its
subsidiaries would be reduced.

</TABLE>
 
    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.
 
                              RECENT DEVELOPMENTS
 
    On November 19, 1997, the Company, through ML Invest plc, an indirect,
wholly owned subsidiary, offered (the "Offer") to acquire all of the outstanding
share capital of Mercury Asset Management Group plc ("MAM") at a price of L17
per share, with an aggregate offer value for the outstanding shares of
approximately L3.1 billion (approximately $5.3 billion). On December 22, 1997,
the Company announced that its Offer had become unconditional in all respects.
As of January 6, 1998, ML Invest plc has received acceptances relating to more
than 90 percent of the outstanding shares of MAM. The Offer will remain open for
acceptances until further notice. Upon confirmation that requisite thresholds
have been attained, the Company will commence the statutory procedure to
compulsorily acquire all MAM shares not tendered into the Offer.

                   MERRILL LYNCH PREFERRED CAPITAL TRUST III
    Merrill Lynch Preferred Capital Trust III (the "Trust") is a statutory
business trust formed under the Delaware Business Trust Act, as amended (the
"Trust Act"), pursuant to a declaration of trust and the filing of a certificate
of trust with the Secretary of State of the State of Delaware on December 19,
1997; such declaration will be amended and restated in its entirety (as so
amended and restated, the "Declaration") substantially in the form filed as an
exhibit to the Registration Statement of which this Prospectus forms a part. The
Declaration will be qualified as an indenture under the Trust Indenture Act of
1939, as amended (the "Trust Indenture Act"). Upon issuance of the Trust
Preferred Securities, the purchasers thereof will own all the Trust Preferred
Securities. See "Description of the Trust Preferred Securities". The Company
will acquire Trust Common Securities in an amount equal to at least 3% of the
total capital of the Trust. The Trust will use all the proceeds derived from the
issuance of the Trust Securities to purchase the Partnership Preferred
Securities from the Partnership and, accordingly, the assets of the Trust will
consist solely of the Partnership Preferred Securities. The Trust exists for the
exclusive purpose of (i) issuing the Trust Securities representing undivided
beneficial ownership interests in the assets of the Trust, (ii) investing the
gross proceeds of the Trust Securities in the Partnership Preferred Securities,
and (iii) engaging in only those other activities necessary or incidental
thereto.
 
    Pursuant to the Declaration, there will initially be four trustees (the
"Trustees") for the Trust. Two of the Trustees will be individuals who are
employees or officers of or who are affiliated with the Company (the "Regular
Trustees"). The third trustee will be a financial institution that is
unaffiliated with the Company and is indenture trustee for purposes of
compliance with the provisions of the Trust Indenture Act (the "Property
Trustee"). The fourth trustee will be an entity that maintains its principal
place of business in the State of Delaware (the "Delaware Trustee"). Initially,
The Chase Manhattan Bank, a New York banking corporation, will act as Property
Trustee, and its affiliate, Chase Manhattan Bank Delaware, a Delaware
corporation, will act as Delaware Trustee until, in each case, removed or
replaced by the holder of the Trust Common Securities. For purposes of
compliance with the Trust Indenture Act, The Chase Manhattan Bank will also act
as trustee under the Trust Guarantee (the "Trust Guarantee Trustee"), as
Property Trustee under the Declaration and as trustee under the indenture
applicable to the Company Debenture.
 
    The Property Trustee will hold title to the Partnership Preferred Securities
for the benefit of the holders of the Trust Securities, and the Property Trustee
will have the power to exercise all rights, powers and privileges with respect
to the Partnership Preferred Securities under the Amended and Restated Agreement
of Limited Partnership to be entered into by the Company and the Trust (the
"Limited Partnership Agreement") as the holder of the Partnership Preferred
Securities. In addition, the Property Trustee will maintain exclusive control of
a segregated non-interest bearing bank account (the "Property Account") to hold
all payments made in respect of the Partnership Preferred Securities for the
benefit of the holders of the Trust Securities. The Trust Guarantee Trustee will
hold the Trust Guarantee for the benefit of the holders of the Trust Preferred
Securities. The Company, as the holder of all the Trust Common Securities, will
have the right to appoint, remove or replace any of the Trustees and to increase
or decrease the number of trustees, provided that at least one trustee shall be
a Delaware Trustee, at least one trustee shall be the Property Trustee and at
least one Trustee shall be a Regular Trustee. The Company will pay all fees and
expenses related to the organization and operations of the Trust (including any
taxes, duties, assessments or governmental charges of whatever nature (other
than withholding taxes) imposed by the United States or any other domestic
taxing authority upon the Trust) and the offering of the Trust Preferred
Securities and be responsible for all debts and obligations of the Trust (other
than with respect to the Trust Securities).
 
    For so long as the Trust Preferred Securities remain outstanding, the
Company will covenant (i) to maintain directly 100% ownership of the Trust
Common Securities, (ii) to cause the Trust to remain a statutory business trust
and not to voluntarily dissolve, wind-up, liquidate or be terminated, except as
permitted by the Declaration of the Trust and (iii) to use its commercially
reasonable efforts to ensure that
 
                                       17
<PAGE>
the Trust will not be (A) an "investment company" for purposes of the 1940 Act
or (B) classified as other than a grantor trust for United States federal income
tax purposes.
 
    The rights of the holders of the Trust Preferred Securities, including
economic rights, rights to information and voting rights, are as set forth in
the Declaration and the Trust Act. See "Description of the Trust Preferred
Securities". The Declaration and the Trust Guarantee also incorporate by
reference the terms of the Trust Indenture Act.
 
    The location of the principal executive office of the Trust is c/o Merrill
Lynch & Co., Inc., World Financial Center, North Tower, 250 Vesey Street, New
York, New York 10281, and its telephone number is (212) 449-1000.
                   MERRILL LYNCH PREFERRED FUNDING III, L.P.
    Merrill Lynch Preferred Funding III, L.P. (the "Partnership") is a limited
partnership that was formed under the Delaware Revised Uniform Limited
Partnership Act, as amended (the "Partnership Act"), on December 19, 1997 for
the exclusive purposes of purchasing certain eligible debt securities of the
Company and wholly-owned subsidiaries of the Company (the "Affiliate Investment
Instruments") with the proceeds from the sale of Partnership Preferred
Securities to the Trust and a capital contribution from the Company in exchange
for the general partner interest in the Partnership. Pursuant to the certificate
of limited partnership, as amended, and the Limited Partnership Agreement, the
Company is the sole general partner of the Partnership (in such capacity the
"General Partner"). Upon the issuance of the Partnership Preferred Securities,
which securities represent limited partner interests in the Partnership, the
Trust will be the sole limited partner of the Partnership. Contemporaneously
with the issuance of the Partnership Preferred Securities, the General Partner
will contribute capital to the Partnership in an amount sufficient to establish
its initial capital account at an amount equal to at least 15% of the total
capital of the Partnership.
 
    The Partnership is managed by the General Partner and exists for the sole
purpose of (i) issuing its partnership interests, (ii) investing the proceeds
thereof in Affiliate Investment Instruments and Eligible Debt Securities and
(iii) engaging in only those other activities necessary or incidental thereto.
To the extent that aggregate payments to the Partnership on the Affiliate
Investment Instruments and on Eligible Debt Securities exceed distributions
accumulated or payable with respect to the Partnership Preferred Securities, the
Partnership may at times have excess funds which shall be allocated to and may,
in the General Partner's sole discretion, be distributed to the General Partner.
 
    For so long as the Partnership Preferred Securities remain outstanding, the
General Partner will covenant in the Limited Partnership Agreement (i) to remain
the sole general partner of the Partnership and to maintain directly 100%
ownership of the General Partner's interest in the Partnership, which interest
will at all times represent at least 1% of the total capital of the Partnership,
(ii) to cause the Partnership to remain a limited partnership and not to
voluntarily dissolve, liquidate, wind-up or be terminated, except as permitted
by the Limited Partnership Agreement and (iii) to use its commercially
reasonable efforts to ensure that the Partnership will not be (A) an "investment
company" for purposes of the 1940 Act or (B) an association or a publicly traded
partnership taxable as a corporation for United States federal income tax
purposes. The Company or the then General Partner may transfer its obligations
as General Partner to a wholly-owned direct or indirect subsidiary of the
Company provided that (i) such successor entity expressly accepts such transfer
of the obligations as General Partner and (ii) prior to such transfer, the
Company has received an opinion of nationally recognized independent counsel to
the Partnership experienced in such matters to the effect that (A) the
Partnership will be treated as a partnership for United States federal income
tax purposes, (B) such transfer would not cause the Trust to be classified as an
association taxable as a corporation for United States federal income tax
purposes, (C) following such transfer, the Company and such successor entity
will be in compliance with the 1940 Act
 
                                       18
<PAGE>
without registering thereunder as an investment company, and (D) such transfer
will not adversely affect the limited liability of the holders of the
Partnership Preferred Securities.
 
    The rights of the holders of the Partnership Preferred Securities, including
economic rights, rights to information and voting rights, are set forth in the
Limited Partnership Agreement and the Partnership Act. See "Description of the
Partnership Preferred Securities".
 
    The Limited Partnership Agreement provides that the General Partner will
have liability for the fees and expenses of the Partnership (including any
taxes, duties, assessments or governmental charges of whatever nature (other
than withholding taxes) imposed by the United States or any other domestic
taxing authority upon the Partnership) and be responsible for all debts and
obligations of the Partnership (other than with respect to the Partnership
Preferred Securities). Under Delaware law, assuming a limited partner in a
Delaware limited partnership such as the Partnership (I.E., a holder of the
Partnership Preferred Securities) does not participate in the control of the
business of the limited partnership, such limited partner will not be personally
liable for the debts, obligations and liabilities of such limited partnership,
whether arising in contract, tort or otherwise, solely by reason of being a
limited partner of such limited partnership (subject to any obligation such
limited partner may have to repay any funds that may have been wrongfully
distributed to it). The Partnership's business and affairs will be conducted by
the General Partner.
 
    The location of the principal executive offices of the Partnership is c/o
Merrill Lynch & Co., Inc., World Financial Center, North Tower, 250 Vesey
Street, New York, New York 10281 and its telephone number is (212) 449-1000.
 
                 DESCRIPTION OF THE TRUST PREFERRED SECURITIES
 
    The Trust Preferred Securities will be issued pursuant to the terms of the
Declaration. The Declaration will be qualified as an indenture under the Trust
Indenture Act. The Property Trustee, The Chase Manhattan Bank, will act as
trustee for the Trust Preferred Securities under the Declaration for purposes of
compliance with the provisions of the Trust Indenture Act. The terms of the
Trust Preferred Securities will include those stated in the Declaration and
those made part of the Declaration by the Trust Indenture Act. The following
summary of the material terms and provisions of the Trust Preferred Securities
does not purport to be complete and is subject to, and qualified in its entirety
by reference to, the Declaration, a copy of which is filed as an exhibit to the
Registration Statement of which this Prospectus is a part, the Trust Act and the
Trust Indenture Act.
 
GENERAL
 
    The Trust Preferred Securities will be issued in fully registered form
without coupons. Trust Preferred Securities will not be issued in bearer form.
See "-- Book-Entry Only Issuance -- The Depository Trust Company".
 
    The Declaration authorizes the Regular Trustees of the Trust to issue the
Trust Securities, which represent undivided beneficial ownership interests in
the assets of the Trust. Title to the Partnership Preferred Securities will be
held by the Property Trustee for the benefit of the holders of the Trust
Securities. The Declaration does not permit the Trust to acquire any assets
other than the Partnership Preferred Securities or the issuance by the Trust of
any securities other than the Trust Securities or the incurrence of any
indebtedness by the Trust. The payment of distributions out of money held by the
Trust, and payments out of money held by the Trust upon redemption of the Trust
Preferred Securities or liquidation of the Trust, are guaranteed by the Company
to the extent described under "Description of the Trust Guarantee". The Trust
Guarantee will be held by The Chase Manhattan Bank, the Trust Guarantee Trustee,
for the benefit of the holders of the Trust Preferred Securities. The Trust
Guarantee does not cover payment of distributions when the Trust does not have
sufficient available funds to pay such
 
                                       19
<PAGE>
distributions. In such event, holders of Trust Preferred Securities will have
the remedies described below under "-- Trust Enforcement Events".
 
DISTRIBUTIONS
 
    The distribution rate on Trust Preferred Securities will be fixed at a rate
per annum of 7% of the stated liquidation amount of $25 per Trust Preferred
Security and will be paid if, as and when the Trust has funds available for
payment. Distributions not paid on the scheduled payment date will accumulate
and compound quarterly at a rate per annum equal to 7%. The term "distribution"
as used herein includes any such compounded amounts unless otherwise stated or
the context otherwise requires. The amount of distributions payable for any
period will be computed on the basis of a 360-day year of twelve 30-day months.
 
    Distributions on the Trust Preferred Securities will be cumulative, will
accumulate from the date of initial issuance and will be payable quarterly in
arrears on each March 30, June 30, September 30 and December 30, commencing
March 30, 1998, if, as and when available for payment, by the Property Trustee,
except as otherwise described below. If distributions are not paid when
scheduled, the accumulated distributions shall be paid to the holders of record
of Trust Preferred Securities as they appear on the books and records of the
Trust on the record date with respect to the payment date for the Trust
Preferred Securities which corresponds to the payment date fixed by the
Partnership with respect to the payment of cumulative distributions on the
Partnership Preferred Securities.
 
    Distributions on the Trust Preferred Securities will be made to the extent
that the Trust has funds available for the payment of such distributions in the
Property Account. Amounts available to the Trust for distribution to the holders
of the Trust Preferred Securities will be limited to payments received by the
Trust from the Partnership with respect to the Partnership Preferred Securities
or from the Company on the Partnership Guarantee or the Trust Guarantee.
Distributions on the Partnership Preferred Securities will be paid only if, as
and when declared in the sole discretion of the Company, as the General Partner
of the Partnership. Pursuant to the Limited Partnership Agreement, the General
Partner is not obligated to declare distributions on the Partnership Preferred
Securities at any time, including upon or following a Partnership Enforcement
Event. See "Description of Partnership Preferred Securities -- Partnership
Enforcement Events".
 
    The assets of the Partnership will consist only of Affiliate Investment
Instruments (which initially will be the Debentures) and Eligible Debt
Securities. To the extent that the issuers (and, where applicable, the Company,
as guarantor) of the securities in which the Partnership invests defer or fail
to make any payment in respect of such securities (or, if applicable, such
guarantees), the Partnership will not have sufficient funds to pay and will not
declare or pay distributions on the Partnership Preferred Securities. If the
Partnership does not declare and pay distributions on the Partnership Preferred
Securities out of funds legally available for distribution, the Trust will not
have sufficient funds to make distributions on the Trust Preferred Securities,
in which event the Trust Guarantee will not apply to such distributions until
the Trust has sufficient funds available therefor. See "Description of the
Partnership Preferred Securities -- Distributions" and "Description of the Trust
Guarantee". In addition, as described under "Risk Factors -- Insufficient Income
or Assets Available to Partnership", the Partnership may not have sufficient
funds to pay current or liquidating distributions on the Partnership Preferred
Securities if (i) at any time that the Partnership is receiving current payments
in respect of the securities held by the Partnership (including the Debentures),
the General Partner, in its sole discretion, does not declare distributions on
the Partnership Preferred Securities and the Partnership receives insufficient
amounts to pay the additional compounded distributions that will accumulate in
respect of the Partnership Preferred Securities, (ii) the Partnership reinvests
the proceeds received in respect of the Debentures upon their retirement or at
their maturities in Affiliate Investment Instruments that do not generate income
in an amount that is sufficient to pay full distributions in respect of the
Partnership Preferred Securities or (iii) the Partnership invests in debt
 
                                       20
<PAGE>
securities of Investment Affiliates that are not guaranteed by the Company and
that cannot be liquidated by the Partnership for an amount sufficient to pay
such distributions in full.
 
    Distributions on the Trust Preferred Securities will be payable to the
holders thereof as they appear on the books and records of the Trust on the
relevant record dates, which will be one Business Day (as defined herein) prior
to the relevant payment dates. Such distributions will be paid through the
Property Trustee who will hold amounts received in respect of the Partnership
Preferred Securities in the Property Account for the benefit of the holders of
the Trust Securities. Subject to any applicable laws and regulations and the
provisions of the Declaration, each such payment will be made as described under
"-- Book-Entry Only Issuance -- The Depository Trust Company" below. In the
event that the Trust Preferred Securities do not remain in book-entry only form,
the relevant record dates shall be the 15th day of the month of the relevant
payment dates. In the event that any date on which distributions are payable on
the Trust Preferred Securities is not a Business Day, payment of the
distribution payable on such date will be made on the next succeeding day which
is a Business Day (without any interest or other payment in respect of the
distribution subject to such delay) except that, if such Business Day is in the
next succeeding calendar year, such payment shall be made on the immediately
preceding Business Day, in each case with the same force and effect as if made
on such date. A "Business Day" shall mean any day other than a day on which
banking institutions in The City of New York are authorized or required by law
to close.
 
TRUST ENFORCEMENT EVENTS
 
    The occurrence, at any time, of (i) arrearages on distributions on the Trust
Preferred Securities that shall exist for six consecutive quarterly distribution
periods, (ii) a default by the Company in respect of any of its obligations
under the Trust Guarantee or (iii) a Partnership Enforcement Event under the
Limited Partnership Agreement, will constitute an enforcement event under the
Declaration with respect to the Trust Securities (a "Trust Enforcement Event");
PROVIDED, that pursuant to the Declaration, the holder of the Trust Common
Securities will be deemed to have waived any Trust Enforcement Event with
respect to the Trust Common Securities until all Trust Enforcement Events with
respect to the Trust Preferred Securities have been cured, waived or otherwise
eliminated. Until such Trust Enforcement Events with respect to the Trust
Preferred Securities have been so cured, waived or otherwise eliminated, the
Property Trustee will be deemed to be acting solely on behalf of the holders of
the Trust Preferred Securities and only the holders of the Trust Preferred
Securities will have the right to direct the Property Trustee with respect to
certain matters under the Declaration and, in the case of a Partnership
Enforcement Event, the Special Representative with respect to certain matters
under the Limited Partnership Agreement. See "Description of the Partnership
Preferred Securities -- Partnership Enforcement Events" for a description of the
events which will trigger the occurrence of a Partnership Enforcement Event.
 
    Upon the occurrence of a Trust Enforcement Event, (a) the Property Trustee,
as the holder of the Partnership Preferred Securities, shall have the right to
enforce the terms of the Partnership Preferred Securities, including the right
to direct the Special Representative to enforce (i) the Partnership's creditors'
rights and other rights with respect to the Affiliate Investment Instruments and
the Investment Guarantees, (ii) the rights of the holders of the Partnership
Preferred Securities under the Partnership Guarantee and (iii) the rights of the
holders of the Partnership Preferred Securities to receive distributions (only
if and to the extent declared out of funds legally available therefor) on the
Partnership Preferred Securities, and (b) the Trust Guarantee Trustee shall have
the right to enforce the terms of the Trust Guarantee, including the right to
enforce the covenant restricting certain payments by the Company and Finance
Subsidiaries.
 
    If the Property Trustee fails to enforce its rights under the Partnership
Preferred Securities after a holder of Trust Preferred Securities has made a
written request, such holder of record of Trust Preferred Securities may
directly institute a legal proceeding against the Partnership and the Special
Representative to enforce the Property Trustee's rights under the Partnership
Preferred Securities without first instituting any legal proceeding against the
Property Trustee, the Trust or any other person or entity. In addition, for
 
                                       21
<PAGE>
so long as the Trust holds any Partnership Preferred Securities, if the Special
Representative fails to enforce its rights on behalf of the Partnership under
the Affiliate Investment Instruments after a holder of Trust Preferred
Securities has made a written request, a holder of record of Trust Preferred
Securities may on behalf of the Partnership directly institute a legal
proceeding against the Investment Affiliates under the Affiliate Investment
Instruments, without first instituting any legal proceeding against the Property
Trustee, the Trust, the Special Representative or the Partnership. In any event,
for so long as the Trust is the holder of any Partnership Preferred Securities,
if a Trust Enforcement Event has occurred and is continuing and such event is
attributable to the failure of an Investment Affiliate to make any required
payment when due on any Affiliate Investment Instrument or the failure of the
Company to make any required payment when due on any Investment Guarantee, then
a holder of Trust Preferred Securities may on behalf of the Partnership directly
institute a proceeding against such Investment Affiliate with respect to such
Affiliate Investment Instrument or against the Company with respect to any such
Investment Guarantee, in each case for enforcement of payment.
 
    Under no circumstances, however, shall the Special Representative have
authority to cause the General Partner to declare distributions on the
Partnership Preferred Securities. As a result, although the Special
Representative may be able to enforce the Partnership's creditors' rights to
accelerate and receive payments in respect of the Affiliate Investment
Instruments and the Investment Guarantees, the Partnership would be entitled to
reinvest such payments in additional Affiliate Investment Instruments, subject
to satisfying the reinvestment criteria described under "Description of the
Partnership Preferred Securities -- Partnership Investments", and Eligible Debt
Securities, rather than declaring and making distributions on the Partnership
Preferred Securities.
 
    The Company and the Trust are each required to file annually with the
Property Trustee an officer's certificate as to its compliance with all
conditions and covenants under the Declaration.
 
MANDATORY REDEMPTION
 
    The Partnership Preferred Securities may be redeemed by the Partnership at
the option of the General Partner, in whole or in part, at any time on or after
March 30, 2008 or at any time in certain circumstances upon the occurrence of a
Partnership Special Event. Upon such redemption of the Partnership Preferred
Securities (either at the option of the General Partner or pursuant to a
Partnership Special Event), the proceeds from such repayment shall
simultaneously be applied to redeem Trust Securities having an aggregate
liquidation amount equal to the Partnership Preferred Securities so redeemed at
an amount per Trust Security equal to $25 plus accumulated and unpaid
distributions thereon; PROVIDED, that holders of the Trust Securities shall be
given not less than 30 nor more than 60 days notice of such redemption. See
"Description of the Partnership Preferred Securities -- General" and "--
Optional Redemption".
 
TRUST SPECIAL EVENT REDEMPTION OR DISTRIBUTION
 
    If, at any time, a Trust Tax Event or a Trust Investment Company Event (each
as hereinafter defined, and each, a "Trust Special Event") shall occur and be
continuing, the Regular Trustees shall, unless the Partnership Preferred
Securities are redeemed in the limited circumstances described below, within 90
days following the occurrence of such Trust Special Event elect to either (i)
dissolve the Trust upon not less than 30 nor more than 60 days notice with the
result that, after satisfaction of creditors of the Trust, if any, Partnership
Preferred Securities would be distributed on a PRO RATA basis to the holders of
the Trust Preferred Securities and the Trust Common Securities in liquidation of
such holders' interests in the Trust; PROVIDED, HOWEVER, that if at the time
there is available to the Trust the opportunity to eliminate, within such 90-day
period, the Trust Special Event by taking some ministerial action, such as
filing a form or making an election, or pursuing some other similar reasonable
measure which in the sole judgment of the Company has or will cause no adverse
effect on the Trust, the Partnership, the Company or the holders of the Trust
Securities and will involve no material cost, the Trust will pursue such measure
in lieu of dissolution or (ii)
 
                                       22
<PAGE>
cause the Trust Preferred Securities to remain outstanding, provided that in the
case of this clause (ii), the Company shall pay any and all expenses incurred by
or payable by the Trust attributable to the Trust Special Event. Furthermore, if
in the case of the occurrence of a Trust Tax Event, the Regular Trustees have
received an opinion (a "Trust Redemption Tax Opinion") of nationally recognized
independent tax counsel experienced in such matters that there is more than an
insubstantial risk that interest payable by one or more of the Investment
Affiliates with respect to the Debentures issued by such Investment Affiliate is
not, or will not be, deductible by such Investment Affiliate for United States
federal income tax purposes even if the Partnership Preferred Securities were
distributed to the holders of the Trust Securities in liquidation of such
holders' interests in the Trust as described above, then the General Partner
shall have the right, within 90 days following the occurrence of such Trust Tax
Event, to elect to cause the Partnership to redeem the Partnership Preferred
Securities in whole (but not in part) for cash upon not less than 30 nor more
than 60 days notice and promptly following such redemption, the Trust Preferred
Securities and Trust Common Securities will be redeemed by the Trust at the
Redemption Price.
 
    "Trust Tax Event" means that the Company shall have requested and received
and shall have delivered to the Regular Trustees an opinion of nationally
recognized independent tax counsel experienced in such matters (a "Trust
Dissolution Tax Opinion") to the effect that there has been (a) an amendment to,
change in or announced proposed change in the laws (or any regulations
thereunder) of the United States or any political subdivision or taxing
authority thereof or therein, (b) a judicial decision interpreting, applying, or
clarifying such laws or regulations, (c) an administrative pronouncement or
action that represents an official position (including a clarification of an
official position) of the governmental authority or regulatory body making such
administrative pronouncement or taking such action, or (d) a threatened
challenge asserted in connection with an audit of the Company or any of its
subsidiaries, the Partnership, or the Trust, or a threatened challenge asserted
in writing against any other taxpayer that has raised capital through the
issuance of securities that are substantially similar to the Debentures, the
Partnership Preferred Securities, or the Trust Preferred Securities, which
amendment or change is adopted or which proposed change, decision or
pronouncement is announced or which action, clarification or challenge occurs on
or after the date of this Prospectus (collectively a "Tax Action"), which Tax
Action relates to any of the items described in (i) through (iii) below, and
that following the occurrence of such Tax Action there is more than an
insubstantial risk that (i) the Trust is, or will be, subject to United States
federal income tax with respect to income accrued or received on the Partnership
Preferred Securities, (ii) the Trust is, or will be, subject to more than a DE
MINIMIS amount of other taxes, duties or other governmental charges or (iii)
interest payable by an Investment Affiliate with respect to the Debenture issued
by such Investment Affiliate is not, or will not be, deductible by such
Investment Affiliate for United States federal income tax purposes.
 
    "Trust Investment Company Event" means that the Company shall have requested
and received and shall have delivered to the Regular Trustees an opinion of
nationally recognized independent legal counsel experienced in such matters to
the effect that as a result of the occurrence on or after the date hereof of a
change in law or regulation or a change in interpretation or application of law
or regulation by any legislative body, court, governmental agency or regulatory
authority (a "Change in 1940 Act Law"), the Trust is or will be considered an
"investment company" which is required to be registered under the 1940 Act.
 
    If the Partnership Preferred Securities are distributed to the holders of
the Trust Preferred Securities, the Company will use its best efforts to cause
the Partnership Preferred Securities to be listed on the New York Stock Exchange
or on such other national securities exchange or similar organization as the
Trust Preferred Securities are then listed or quoted.
 
                                       23
<PAGE>
    On the date fixed for any distribution of Partnership Preferred Securities,
upon dissolution of the Trust, (i) the Trust Preferred Securities and the Trust
Common Securities will no longer be deemed to be outstanding and (ii)
certificates representing Trust Securities will be deemed to represent the
Partnership Preferred Securities having a liquidation preference equal to the
stated liquidation amount of such Trust Securities until such certificates are
presented to the Company or its agent for transfer or reissuance.
 
    There can be no assurance as to the market price for the Partnership
Preferred Securities which may be distributed in exchange for Trust Preferred
Securities if a dissolution and liquidation of the Trust were to occur.
Accordingly, the Partnership Preferred Securities which an investor may
subsequently receive on dissolution and liquidation of the Trust may trade at a
discount to the price of the Trust Preferred Securities exchanged.
 
REDEMPTION PROCEDURES
 
    The Trust may not redeem fewer than all of the outstanding Trust Preferred
Securities unless all accumulated and unpaid distributions have been paid on all
Trust Preferred Securities for all quarterly distribution periods terminating on
or prior to the date of redemption.
 
    If the Trust gives a notice of redemption in respect of Trust Preferred
Securities (which notice will be irrevocable), and if the Company has paid to
the Property Trustee a sufficient amount of cash in connection with the related
redemption of the Partnership Preferred Securities, then, by 12:00 noon, New
York time, on the redemption date, the Trust will irrevocably deposit with DTC
funds sufficient to pay the amount payable on redemption of all book-entry
certificates and will give DTC irrevocable instructions and authority to pay
such amount to holders of the Trust Preferred Securities. See "-- Book-Entry
Only Issuance -- The Depository Trust Company". If notice of redemption shall
have been given and funds are deposited as required, then upon the date of such
deposit, all rights of holders of such Trust Preferred Securities so called for
redemption will cease, except the right of the holders of such Trust Preferred
Securities to receive the Redemption Price, but without interest on such
Redemption Price. In the event that any date fixed for redemption of Trust
Preferred Securities is not a Business Day, then payment of the amount payable
on such date will be made on the next succeeding day which is a Business Day
(without any interest or other payment in respect of the amount payable subject
to such delay), except that, if such Business Day falls in the next calendar
year, such payment will be made on the immediately preceding Business Day. In
the event that payment of the Redemption Price in respect of Trust Preferred
Securities is improperly withheld or refused and not paid either by the Trust or
by the Company pursuant to the Trust Guarantee described under "Description of
the Trust Guarantee", distributions on such Trust Preferred Securities will
continue to accumulate from the original redemption date to the date of payment.
 
    In the event that fewer than all of the outstanding Trust Preferred
Securities are to be redeemed, the Trust Preferred Securities will be redeemed
in accordance with the procedures of DTC. See "-- Book-Entry Only Issuance --
The Depository Trust Company". In the event that the Trust Preferred Securities
do not remain in book-entry only form and fewer than all of the outstanding
Trust Preferred Securities are to be redeemed, the Trust Preferred Securities
shall be redeemed on a PRO RATA basis or pursuant to the rules of any securities
exchange on which the Trust Preferred Securities are listed.
 
    Subject to the foregoing and applicable law (including, without limitation,
United States federal securities laws), the Company or its subsidiaries may at
any time and from time to time purchase outstanding Trust Preferred Securities
by tender, in the open market or by private agreement.
 
SUBORDINATION OF TRUST COMMON SECURITIES
 
    Payment of amounts upon liquidation of the Trust Securities shall be made
PRO RATA based on the liquidation amount of the Trust Securities; PROVIDED,
HOWEVER, that upon (i) the occurrence of an Investment Event of Default by an
Investment Affiliate (including the Company) in respect of any Affiliate
Investment Instrument or (ii) default by the Company on any of its obligations
under any Guarantee, the
 
                                       24
<PAGE>
holders of the Trust Preferred Securities will have a preference over the
holders of the Trust Common Securities with respect to payments upon liquidation
of the Trust.
 
    In the case of any Trust Enforcement Event, the holder of Trust Common
Securities will be deemed to have waived any such Trust Enforcement Event until
all such Trust Enforcement Events with respect to the Trust Preferred Securities
have been cured, waived or otherwise eliminated. Until all Trust Enforcement
Events with respect to the Trust Preferred Securities have been so cured, waived
or otherwise eliminated, the Property Trustee shall act solely on behalf of the
holders of the Trust Preferred Securities and not on behalf of the holder of the
Trust Common Securities, and only the holders of the Trust Preferred Securities
will have the right to direct the Property Trustee to act on their behalf.
 
LIQUIDATION DISTRIBUTION UPON DISSOLUTION
 
    In the event of any voluntary or involuntary liquidation, dissolution,
winding-up or termination of the Trust (each a "Trust Liquidation"), the holders
of the Trust Preferred Securities will be entitled to receive out of the assets
of the Trust, after satisfaction of liabilities to creditors, distributions in
cash or other immediately available funds in an amount equal to the aggregate of
the stated liquidation amount of $25 per Trust Preferred Security plus
accumulated and unpaid distributions thereon to the date of payment (the "Trust
Liquidation Distribution"), unless, in connection with such Trust Liquidation,
Partnership Preferred Securities have been distributed on a PRO RATA basis to
the holders of the Trust Securities.
 
    If, upon any such Trust Liquidation, the Trust Liquidation Distribution can
be paid only in part because the Trust has insufficient assets available to pay
in full the aggregate Trust Liquidation Distribution, then the amounts payable
directly by the Trust on the Trust Preferred Securities shall be paid on a PRO
RATA basis. The holders of the Trust Common Securities will be entitled to
receive distributions upon any such liquidation PRO RATA with the holders of the
Trust Preferred Securities, except in the limited circumstances described above
under "-- Subordination of Trust Common Securities".
 
    Pursuant to the Declaration, the Trust shall terminate (i) upon the
bankruptcy of the Company, (ii) upon the filing of a certificate of dissolution
or the equivalent with respect to the Company, the filing of a certificate of
cancellation with respect to the Trust after having obtained the consent of at
least a majority in liquidation amount of the Trust Securities, voting together
as a single class, to file such certificate of cancellation, or the revocation
of the charter of the Company and the expiration of 90 days after the date of
revocation without a reinstatement thereof, (iii) upon the distribution of all
of the Partnership Preferred Securities upon the occurrence of a Trust Special
Event, (iv) upon the entry of a decree of a judicial dissolution of the Company
or the Trust, or (v) upon the redemption of all the Trust Securities.
 
VOTING RIGHTS
 
    Except as described herein, under the Trust Act, the Trust Indenture Act and
under "Description of the Trust Guarantee -- Amendments and Assignment", and as
otherwise required by law and the Declaration, the holders of the Trust
Preferred Securities will have no voting rights.
 
    Subject to the requirement of the Property Trustee obtaining a tax opinion
as set forth in the last sentence of this paragraph, the holders of a majority
in liquidation amount of the Trust Preferred Securities have the right to direct
the time, method and place of conducting any proceeding for any remedy available
to the Property Trustee, or direct the exercise of any trust or power conferred
upon the Property Trustee under the Declaration, including the right to direct
the Property Trustee, as holder of the Partnership Preferred Securities, to (i)
exercise the remedies available to it under the Limited Partnership Agreement as
a holder of the Partnership Preferred Securities, including the right to direct
the Special Representative to exercise its rights in the manner described above
under "-- Trust Enforcement Events" and (ii) consent to any amendment,
modification, or termination of the Limited Partnership Agreement or the
Partnership Preferred Securities where such consent shall be required; PROVIDED,
HOWEVER, that where a
 
                                       25
<PAGE>
consent or action under the Limited Partnership Agreement would require the
consent or act of the holders of more than a majority of the aggregate
liquidation preference of Partnership Preferred Securities affected thereby,
only the holders of the percentage of the aggregate stated liquidation amount of
the Trust Securities which is at least equal to the percentage required under
the Limited Partnership Agreement may direct the Property Trustee to give such
consent or take such action on behalf of the Trust. See "Description of the
Partnership Preferred Securities -- Voting Rights". The Property Trustee shall
notify all holders of the Trust Preferred Securities of any notice of any
Partnership Enforcement Event received from the General Partner with respect to
the Partnership Preferred Securities and the Affiliate Investment Instruments.
Such notice shall state that such Partnership Enforcement Event also constitutes
a Trust Enforcement Event. Except with respect to directing the time, method,
and place of conducting a proceeding for a remedy as described above, the
Property Trustee shall be under no obligation to take any of the actions
described in clauses (i) or (ii) above unless the Property Trustee has obtained
an opinion of independent tax counsel to the effect that as a result of such
action, the Trust will not fail to be classified as a grantor trust for United
States federal income tax purposes and that after such action each holder of
Trust Securities will continue to be treated as owning an undivided beneficial
ownership interest in the Partnership Preferred Securities.
 
    A waiver of a Partnership Enforcement Event with respect to the Partnership
Preferred Securities held by the Property Trustee will constitute a waiver of
the corresponding Trust Enforcement Event.
 
    Any required approval or direction of holders of Trust Preferred Securities
may be given at a separate meeting of holders of Trust Preferred Securities
convened for such purpose, at a meeting of all of the holders of Trust
Securities or pursuant to written consent. The Regular Trustees will cause a
notice of any meeting at which holders of Trust Preferred Securities are
entitled to vote, or of any matter upon which action by written consent of such
holders is to be taken, to be mailed to each holder of record of Trust Preferred
Securities. Each such notice will include a statement setting forth the
following information: (i) the date of such meeting or the date by which such
action is to be taken; (ii) a description of any resolution proposed for
adoption at such meeting on which such holders are entitled to vote or of such
matter upon which written consent is sought; and (iii) instructions for the
delivery of proxies or consents. No vote or consent of the holders of Trust
Preferred Securities will be required for the Trust to redeem and cancel Trust
Preferred Securities or distribute Partnership Preferred Securities in
accordance with the Declaration.
 
    Notwithstanding that holders of Trust Preferred Securities are entitled to
vote or consent under any of the circumstances described above, any of the Trust
Securities that are beneficially owned at such time by the Company or any entity
directly or indirectly controlled by, or under direct or indirect common control
with, the Company, except for Trust Preferred Securities purchased or acquired
by the Company or its affiliates in connection with transactions effected by or
for the account of customers of the Company or any of its subsidiaries or in
connection with the distribution or trading of such Trust Preferred Securities,
shall not be entitled to vote or consent and shall, for purposes of such vote or
consent, be treated as if such Trust Securities were not outstanding; PROVIDED,
HOWEVER, that persons (other than affiliates of the Company) to whom the Company
or any of its subsidiaries have pledged Trust Preferred Securities may vote or
consent with respect to such pledged Trust Preferred Securities pursuant to the
terms of such pledge.
 
    The procedures by which holders of Trust Preferred Securities represented by
the global certificates may exercise their voting rights are described below.
See "-- Book-Entry Only Issuance -- The Depository Trust Company".
 
    Holders of the Trust Preferred Securities will have no rights to appoint or
remove the Regular Trustees, who may be appointed, removed or replaced solely by
the Company, as the holder of all of the Trust Common Securities.
 
                                       26
<PAGE>
MERGER, CONSOLIDATION OR AMALGAMATION OF THE TRUST
 
    The Trust may not consolidate, amalgamate, merge with or into, or be
replaced by, or convey, transfer or lease its properties and assets
substantially as an entirety to, any corporation or other entity, except as
described below. The Trust may, with the consent of a majority of the Regular
Trustees and without the consent of the holders of the Trust Securities, the
Property Trustee or the Delaware Trustee consolidate, amalgamate, merge with or
into, or be replaced by a trust organized as such under the laws of any State of
the United States; PROVIDED, that (i) if the Trust is not the survivor, such
successor entity either (x) expressly assumes all of the obligations of the
Trust under the Trust Securities or (y) substitutes for the Trust Preferred
Securities other securities having substantially the same terms as the Trust
Preferred Securities (the "Successor Securities"), so long as the Successor
Securities rank the same as the Trust Securities rank with respect to
distributions, assets and payments, (ii) the Company expressly acknowledges a
trustee of such successor entity possessing the same powers and duties as the
Property Trustee as the holder of the Partnership Preferred Securities, (iii)
the Trust Preferred Securities or any Successor Securities are listed, or any
Successor Securities will be listed upon notification of issuance, on any
national securities exchange or with another organization on which the Trust
Preferred Securities are then listed or quoted, (iv) such merger, consolidation,
amalgamation or replacement does not cause the Trust Preferred Securities
(including any Successor Securities) to be downgraded by any nationally
recognized statistical rating organization, (v) such merger, consolidation,
amalgamation or replacement does not adversely affect the rights, preferences
and privileges of the holders of the Trust Preferred Securities (including any
Successor Securities) in any material respect, (vi) such successor entity has a
purpose substantially identical to that of the Trust, (vii) the Company
guarantees the obligations of such successor entity under the Successor
Securities to the same extent as provided by the Trust Guarantee and (viii)
prior to such merger, consolidation, amalgamation or replacement, the Company
has received an opinion of a nationally recognized independent counsel to the
Trust experienced in such matters to the effect that: (A) such merger,
consolidation, amalgamation or replacement will not adversely affect the rights,
preferences and privileges of the holders of the Trust Preferred Securities
(including any Successor Securities) in any material respect (other than with
respect to any dilution of the holders' interest in the new entity), (B)
following such merger, consolidation, amalgamation or replacement, neither the
Trust nor such successor entity will be required to register as an investment
company under the 1940 Act, (C) following such merger, consolidation,
amalgamation or replacement, the Trust (or such successor trust) will not be
classified as an association or a publicly traded partnership taxable as a
corporation for United States federal income tax purposes and (D) following such
merger, consolidation, amalgamation or replacement, the Partnership will not be
classified as an association or a publicly traded partnership taxable as a
corporation for United States federal income tax purposes. Notwithstanding the
foregoing, the Trust shall not, except with the consent of holders of 100% in
liquidation amount of the Trust Preferred Securities, consolidate, amalgamate,
merge with or into, or be replaced by any other entity or permit any other
entity to consolidate, amalgamate, merge with or into, or replace it, if such
consolidation, amalgamation, merger or replacement would cause the Trust or the
successor entity to be classified as an association or a publicly traded
partnership taxable as a corporation for United States federal income tax
purposes.
 
MODIFICATION OF THE DECLARATION
 
    The Declaration may be modified and amended if approved by a majority of the
Regular Trustees (and in certain circumstances the Property Trustee and the
Delaware Trustee), PROVIDED, that if any proposed amendment provides for, or the
Regular Trustees otherwise propose to effect, (i) any action that would
adversely affect the powers, preferences or special rights of the Trust
Securities, whether by way of amendment to the Declaration or otherwise or (ii)
the dissolution, winding-up or termination of the Trust other than pursuant to
the terms of the Declaration, then the holders of the Trust Securities voting
together as a single class will be entitled to vote on such amendment or
proposal and such amendment or proposal shall not be effective except with the
approval of at least a majority in liquidation amount of the Trust Securities
affected thereby; PROVIDED, FURTHER that if any amendment or proposal referred
to in clause
 
                                       27
<PAGE>
(i) above would adversely affect only the Trust Preferred Securities or the
Trust Common Securities, then only the affected class will be entitled to vote
on such amendment or proposal and such amendment or proposal shall not be
effective except with the approval of a majority in liquidation amount of such
class of Trust Securities.
 
    The Declaration may be amended without the consent of the holders of the
Trust Securities to (i) cure any ambiguity, (ii) correct or supplement any
provision in the Declaration that may be defective or inconsistent with any
other provision of the Declaration, (iii) add to the covenants, restrictions or
obligations of the Sponsor, (iv) conform to any change in the 1940 Act, the
Trust Indenture Act or the rules or regulations of either such Act and (v)
modify, eliminate and add to any provision of the Declaration to such extent as
may be necessary or desirable; PROVIDED that no such amendment shall have a
material adverse effect on the rights, preferences or privileges of the holders
of the Trust Securities.
 
    Notwithstanding the foregoing, no amendment or modification may be made to
the Declaration if such amendment or modification would (i) cause the Trust to
fail to be classified as a grantor trust for United States federal income tax
purposes, (ii) cause the Partnership to be classified as an association or
publicly traded partnership taxable as a corporation for such purposes, (iii)
reduce or otherwise adversely affect the powers of the Property Trustee or (iv)
cause the Trust or the Partnership to be deemed an "investment company" which is
required to be registered under the 1940 Act.
 
BOOK-ENTRY ONLY ISSUANCE -- THE DEPOSITORY TRUST COMPANY
 
    The Depository Trust Company ("DTC") will act as securities depository (the
"Depository") for the Trust Preferred Securities and, to the extent distributed
to the holders of Trust Preferred Securities, the Partnership Preferred
Securities. The Trust Preferred Securities will be issued only as
fully-registered securities registered in the name of Cede & Co. (DTC's
nominee). One or more fully-registered global Trust Preferred Securities
certificates ("Global Certificates"), representing the total aggregate number of
Trust Preferred Securities, will be issued and will be deposited with DTC.
 
    DTC 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. DTC
holds securities that its participants ("Participants") deposit with DTC. DTC
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 physical movement of securities certificates. Participants in DTC
include securities brokers and dealers, banks, trust companies, clearing
corporations and certain other organizations. DTC is owned by a number of its
Participants and by the New York Stock Exchange, the American Stock Exchange,
Inc., and the National Association of Securities Dealers, Inc. Access to the DTC
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 Participant, either directly or indirectly ("Indirect Participants"). The
rules applicable to DTC and its Participants are on file with the Commission.
 
    Purchases of Trust Preferred Securities within the DTC system must be made
by or through Participants, which will receive a credit for the Trust Preferred
Securities on DTC's records. The ownership interest of each actual purchaser of
Trust Preferred Securities ("Beneficial Owner") is in turn to be recorded on the
Participants' and Indirect Participants' records. Beneficial Owners will not
receive written confirmation from DTC of their purchases, but Beneficial Owners
are expected to receive written confirmations providing details of the
transactions, as well as periodic statements of their holdings, from the
Participants or Indirect Participants through which the Beneficial Owners
purchased Trust Preferred Securities. Transfers of ownership interests in the
Trust Preferred Securities are to be accomplished by entries made on the books
of Participants and Indirect Participants acting on behalf of Beneficial Owners.
 
                                       28
<PAGE>
Beneficial Owners will not receive certificates representing their ownership
interests in Trust Preferred Securities, except in the event that use of the
book-entry system for the Trust Preferred Securities is discontinued.
 
    DTC has no knowledge of the actual Beneficial Owners of the Trust Preferred
Securities; DTC's records reflect only the identity of the Participants to whose
accounts such Trust Preferred Securities are credited, which may or may not be
the Beneficial Owners. The Participants and Indirect Participants will remain
responsible for keeping account of their holdings on behalf of their customers.
 
    So long as DTC, or its nominee, is the registered owner or holder of a
Global Certificate, DTC or such nominee, as the case may be, will be considered
the sole owner or holder of the Trust Preferred Securities represented thereby
for all purposes under the Declaration and the Trust Preferred Securities. No
beneficial owner of an interest in a Global Certificate will be able to transfer
that interest except in accordance with DTC's applicable procedures, in addition
to those provided for under the Declaration.
 
    DTC has advised the Company that it will take any action permitted to be
taken by a holder of Trust Preferred Securities (including the presentation of
Trust Preferred Securities for exchange as described below) only at the
direction of one or more Participants to whose account the DTC interests in the
Global Certificates are credited and only in respect of such portion of the
aggregate liquidation amount of Trust Preferred Securities as to which such
Participant or Participants has or have given such direction. Also, if there is
a Trust Enforcement Event under the Trust Preferred Securities, DTC will
exchange the Global Certificates for Certificated Securities, which it will
distribute to its Participants in accordance with its customary procedures.
 
    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.
 
    Redemption notices in respect of the Trust Preferred Securities held in
book-entry form will be sent to Cede & Co. If less than all of the Trust
Preferred Securities are being redeemed, DTC will determine the amount of the
interest of each Participant to be redeemed in accordance with its procedures.
 
    Although voting with respect to the Trust Preferred Securities is limited,
in those cases where a vote is required, neither DTC nor Cede & Co. will itself
consent or vote with respect to Trust Preferred Securities. Under its usual
procedures, DTC would mail an Omnibus Proxy to the Trust as soon as possible
after the record date. The Omnibus Proxy assigns Cede & Co.'s consenting or
voting rights to those Participants to whose accounts the Trust Preferred
Securities are allocated on the record date (identified in a listing attached to
the Omnibus Proxy).
 
    Distributions on the Trust Preferred Securities held in book-entry form will
be made to DTC in immediately available funds. DTC's practice is to credit
Participants' accounts on the relevant payment date in accordance with their
respective holdings shown on DTC's records unless DTC has reason to believe that
it will not receive payments on such payment date. Payments by Participants and
Indirect Participants to Beneficial Owners will be governed by standing
instructions and customary practices and will be the responsibility of such
Participants and Indirect Participants and not of DTC, the Trust or the Company,
subject to any statutory or regulatory requirements as may be in effect from
time to time. Payment of any distributions to DTC is the responsibility of the
Trust, disbursement of such payments to Participants is the responsibility of
DTC, and disbursement of such payments to the Beneficial Owners is the
responsibility of Participants and Indirect Participants.
 
    Except as described, a Beneficial Owner of an interest in a Global
Certificate will not be entitled to receive physical delivery of Trust Preferred
Securities. Accordingly, each Beneficial Owner must rely on the procedures of
DTC to exercise any rights under the Trust Preferred Securities.
 
                                       29
<PAGE>
    Although DTC has agreed to the foregoing procedures in order to facilitate
transfers of interests in the Global Certificates among Participants of DTC, DTC
is under no obligation to perform or continue to perform such procedures, and
such procedures may be discontinued at any time. Neither the Company nor the
Trust will have any responsibility for the performance by DTC or its
Participants or Indirect Participants under the rules and procedures governing
DTC. DTC may discontinue providing its services as securities depository with
respect to the Trust Preferred Securities at any time by giving notice to the
Trust. Under such circumstances, in the event that a successor securities
depository is not obtained, Trust Preferred Security certificates are required
to be printed and delivered to the Property Trustee. Additionally, the Trust
(with the consent of the Company) may decide to discontinue use of the system of
book-entry transfers through DTC or any successor depository. In that event,
certificates for the Trust Preferred Securities will be printed and delivered to
the Property Trustee. In each of the above circumstances, the Company will
appoint a paying agent with respect to the Trust Preferred Securities.
 
    The laws of some jurisdictions require that certain purchasers of securities
take physical delivery of securities in definitive form. Such laws may impair
the ability to transfer beneficial interests in the global Trust Preferred
Securities as represented by a Global Certificate.
 
PAYMENT
 
    Payments in respect of the Trust Preferred Securities represented by the
Global Certificates shall be made to DTC, which shall credit the relevant
accounts at DTC on the scheduled payment dates or, in the case of certificated
securities, if any, such payments shall be made by check mailed to the address
of the holder entitled thereto as such address shall appear on the register. The
Paying Agent shall be permitted to resign as Paying Agent upon 30 days written
notice to the Regular Trustees. In the event that The Chase Manhattan Bank shall
no longer be the Paying Agent, the Regular Trustees shall appoint a successor to
act as Paying Agent (which shall be a bank or trust company).
 
REGISTRAR, TRANSFER AGENT, AND PAYING AGENT
 
    The Property Trustee will act as Registrar, Transfer Agent and Paying Agent
for the Trust Preferred Securities.
 
    Registration of transfers of Trust Preferred Securities will be effected
without charge by or on behalf of the Trust, but upon payment (with the giving
of such indemnity as the Trust or the Company may require) in respect of any tax
or other government charges which may be imposed in relation to it.
 
    The Trust will not be required to register or cause to be registered the
transfer of Trust Preferred Securities after such Trust Preferred Securities
have been called for redemption.
 
INFORMATION CONCERNING THE PROPERTY TRUSTEE
 
    The Property Trustee, prior to the occurrence of a default with respect to
the Trust Securities, undertakes to perform only such duties as are specifically
set forth in the Declaration and, after default, shall exercise the same degree
of care as a prudent individual would exercise in the conduct of his or her own
affairs. Subject to such provisions, the Property Trustee is under no obligation
to exercise any of the powers vested in it by the Declaration at the request of
any holder of Trust Preferred Securities, unless offered reasonable indemnity by
such holder against the costs, expenses and liabilities which might be incurred
thereby. The holders of Trust Preferred Securities will not be required to offer
such indemnity in the event such holders, by exercising their voting rights,
direct the Property Trustee to take any action following a Trust Enforcement
Event.
 
GOVERNING LAW
 
    The Declaration and the Trust Preferred Securities will be governed by, and
construed in accordance with, the internal laws of the State of Delaware.
 
                                       30
<PAGE>
MISCELLANEOUS
 
    The Regular Trustees are authorized and directed to conduct the affairs of
and to operate the Trust in such a way that the Trust will not be deemed to be
an "investment company" required to be registered under the 1940 Act or
characterized as other than a grantor trust for United States federal income tax
purposes. In this connection, the Regular Trustees are authorized to take any
action, not inconsistent with applicable law, the certificate of trust or the
Declaration that the Regular Trustees determine in their discretion to be
necessary or desirable for such purposes as long as such action does not
adversely affect the interests of the holders of the Trust Preferred Securities.
 
    Holders of the Trust Preferred Securities have no preemptive rights.
 
                       DESCRIPTION OF THE TRUST GUARANTEE
 
    Set forth below is a summary of information concerning the Trust Guarantee
which will be executed and delivered by the Company for the benefit of the
holders from time to time of Trust Preferred Securities. The summary does not
purport to be complete and is subject in all respects to the provisions of, and
is qualified in its entirety by reference to, the Trust Guarantee, which is
filed as an exhibit to the Registration Statement of which this Prospectus is a
part. The Trust Guarantee incorporates by reference the terms of, and will be
qualified as an indenture under, the Trust Indenture Act. The Chase Manhattan
Bank, as the Trust Guarantee Trustee, will hold the Trust Guarantee for the
benefit of the holders of the Trust Preferred Securities and will act as
indenture trustee for the purposes of compliance with the Trust Indenture Act.
 
GENERAL
 
    Pursuant to the Trust Guarantee, the Company will irrevocably agree, on a
subordinated basis and to the extent set forth therein, to pay in full to the
holders of the Trust Preferred Securities (except to the extent paid by the
Trust), as and when due, regardless of any defense, right of set off or
counterclaim which the Trust may have or assert, the following payments (the
"Trust Guarantee Payments"), without duplication: (i) any accumulated and unpaid
distributions on the Trust Preferred Securities to the extent the Trust has
funds available therefor, (ii) the Redemption Price with respect to any Trust
Preferred Securities called for redemption by the Trust, to the extent the Trust
has funds available therefor and (iii) upon a voluntary or involuntary
dissolution, winding-up or termination of the Trust (other than in connection
with the distribution of Partnership Preferred Securities to the holders of
Trust Preferred Securities or the redemption of all of the Trust Preferred
Securities), the lesser of (a) the aggregate of the liquidation amount and all
accumulated and unpaid distributions on the Trust Preferred Securities and (b)
the amount of assets of the Trust remaining available for distribution to
holders of Trust Preferred Securities upon the liquidation of the Trust. The
Company's obligation to make a Trust Guarantee Payment may be satisfied by
direct payment of the required amounts by the Company to the holders of Trust
Preferred Securities or by causing the Trust to pay such amounts to such
holders.
 
    The Trust Guarantee will be a guarantee on a subordinated basis with respect
to the Trust Preferred Securities from the time of issuance of such Trust
Preferred Securities but will only apply to any payment of distributions or
Redemption Price, or to payments upon the dissolution, winding-up or termination
of the Trust, to the extent the Trust shall have funds available therefor. If
the Partnership fails to declare distributions on Partnership Preferred
Securities, the Trust would lack available funds for the payment of
distributions or amounts payable on redemption of the Trust Preferred Securities
or otherwise, and in such event holders of the Trust Preferred Securities would
not be able to rely upon the Trust Guarantee for payment of such amounts.
Instead, holders of the Trust Preferred Securities will have the remedies
described herein under "Description of the Trust Preferred Securities -- Trust
Enforcement Events", including the right to direct the Trust Guarantee Trustee
to enforce the covenant restricting certain payments by the Company and Finance
Subsidiaries. See "-- Covenants of the Company" below.
 
                                       31
<PAGE>
    The Guarantees, when taken together with the Company Debenture and the
Company's obligations to pay all fees and expenses of the Trust and the
Partnership, constitute a guarantee to the extent set forth herein by the
Company of the distribution, redemption and liquidation payments payable to the
holders of the Trust Preferred Securities. The Guarantees do not apply, however,
to current distributions by the Partnership unless and until such distributions
are declared by the Partnership out of funds legally available for payment or to
liquidating distributions unless there are assets available for payment in the
Partnership, each as more fully described under "Risk Factors -- Insufficient
Income or Assets Available to Partnership".
 
COVENANTS OF THE COMPANY
 
    The Company will covenant in the Trust Guarantee that, if (a) for any
distribution period, full distributions on a cumulative basis on any Trust
Preferred Securities have not been paid, (b) an Investment Event of Default by
any Investment Affiliate in respect of any Affiliate Investment Instrument has
occurred and is continuing or (c) the Company is in default of its obligations
under the Trust Guarantee, the Partnership Guarantee or any Investment
Guarantee, then, during such period (i) the Company shall not declare or pay
dividends on, make distributions with respect to, or redeem, purchase or
acquire, or make a liquidation payment with respect to, any of its capital stock
or comparable equity interest (except for (x) dividends or distributions in
shares of, or options, warrants or rights to subscribe for or purchase shares
of, its capital stock, and conversions or exchanges of common stock of one class
into common stock of another class, (y) redemptions or purchases of any rights
pursuant to the Rights Agreement and the issuance of preferred stock pursuant to
such rights and (z) purchases or acquisitions by the Company or its affiliates
in connection with transactions effected by or for the account of customers of
the Company or any of its subsidiaries or in connection with the distribution or
trading of such capital stock or comparable equity interest) and (ii) the
Company shall not make, permit any Finance Subsidiary to make, or make any
payments that would enable any Finance Subsidiary to make, any payment of any
dividends on, any distribution with respect to, or any redemption, purchase or
other acquisition of, or any liquidation payment with respect to, any preferred
security or comparable equity interest of any Finance Subsidiary.
 
EVENTS OF DEFAULT; ENFORCEMENT OF TRUST GUARANTEE
 
    An event of default under the Trust Guarantee will occur upon the failure of
the Company to perform any of its payment or other obligations thereunder.
 
    The holders of a majority in liquidation amount of the Trust Preferred
Securities have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Trust Guarantee Trustee or to direct
the exercise of any trust or power conferred upon the Trust Guarantee Trustee
under the Trust Guarantee. If the Trust Guarantee Trustee fails to enforce its
rights under the Trust Guarantee after a holder of Trust Preferred Securities
has made a written request, such holder may institute a legal proceeding
directly against the Company to enforce the Trust Guarantee Trustee's rights
under the Trust Guarantee, without first instituting a legal proceeding against
the Trust, the Trust Guarantee Trustee or any other person or entity. In any
event, if the Company has failed to make a guarantee payment under the Trust
Guarantee, a holder of Trust Preferred Securities may directly institute a
proceeding in such holder's own name against the Company for enforcement of the
Trust Guarantee for such payment.
 
STATUS OF THE TRUST GUARANTEE; SUBORDINATION
 
    The Trust Guarantee will constitute an unsecured obligation of the Company
and will rank subordinate and junior in right of payment to all other
liabilities of the Company and will rank PARI PASSU with the most senior
preferred stock, if any, issued from time to time by the Company, with similar
guarantees issued by the Company in connection with the $275,000,000 aggregate
liquidation amount of 7 3/4% Trust Originated Preferred Securities issued by
Merrill Lynch Preferred Capital Trust I and the $300,000,000 aggregate
liquidation amount of 8% Trust Originated Preferred Securities issued by Merrill
 
                                       32
<PAGE>
Lynch Preferred Capital Trust II, and with any guarantee now or hereafter
entered into by the Company in respect of any preferred stock of any other
Finance Subsidiary. Accordingly, the rights of the holders of Trust Preferred
Securities to receive payments under the Trust Guarantee will be subject to the
rights of the holders of any obligations of the Company that are senior in
priority to the obligations under the Trust Guarantee. Furthermore, the holders
of obligations of the Company that are senior to the obligations under the Trust
Guarantee (including, but not limited to, obligations constituting Senior
Indebtedness) will be entitled to the same rights upon payment default or
dissolution, liquidation and reorganization in respect of the Trust Guarantee
that inure to the holders of Senior Indebtedness as against the holders of the
Company Debenture. The terms of the Trust Preferred Securities provide that each
holder of Trust Preferred Securities, by acceptance thereof, agrees to the
subordination provisions and other terms of the Trust Guarantee.
 
    The Trust Guarantee will constitute a guarantee of payment and not of
collection (that is, the guaranteed party may directly institute a legal
proceeding against the Company to enforce its rights under the Trust Guarantee
without instituting a legal proceeding against any other person or entity).
 
AMENDMENTS AND ASSIGNMENT
 
    Except with respect to any changes that do not materially adversely affect
the rights of holders of Trust Preferred Securities (in which case no vote will
be required), the Trust Guarantee may be amended only with the prior approval of
the holders of at least a majority in liquidation amount of all the outstanding
Trust Preferred Securities. The manner of obtaining any such approval of holders
of the Trust Preferred Securities will be as set forth under "Description of the
Trust Preferred Securities -- Voting Rights". All guarantees and agreements
contained in the Trust Guarantee shall bind the successors, assigns, receivers,
trustees and representatives of the Company and shall inure to the benefit of
the holders of the Trust Preferred Securities then outstanding. Except in
connection with permitted merger or consolidation of the Company with or into
another entity or permitted sale, transfer or lease of the Company's assets to
another entity in which the surviving corporation (if other than the Company)
assumes the Company's obligations under the Trust Guarantee, the Company may not
assign its rights or delegate its obligations under the Trust Guarantee without
the prior approval of the holders of at least a majority of the aggregate stated
liquidation amount of the Trust Preferred Securities then outstanding.
 
TERMINATION OF THE TRUST GUARANTEE
 
    The Trust Guarantee will terminate as to each holder of Trust Preferred
Securities upon (i) full payment of the Redemption Price of all Trust Preferred
Securities, (ii) distribution of the Partnership Preferred Securities held by
the Trust to the holders of the Trust Preferred Securities or (iii) full payment
of the amounts payable in accordance with the Declaration upon liquidation of
the Trust. The Trust Guarantee will continue to be effective or will be
reinstated, as the case may be, if at any time any holder of Trust Preferred
Securities must restore payment of any sum paid under such Trust Preferred
Securities or such Trust Guarantee.
 
INFORMATION CONCERNING THE TRUST GUARANTEE TRUSTEE
 
    The Trust Guarantee Trustee, prior to the occurrence of a default with
respect to the Trust Guarantee, undertakes to perform only such duties as are
specifically set forth in the Trust Guarantee and, after default with respect to
the Trust Guarantee, shall exercise the same degree of care as a prudent man
would exercise in the conduct of his own affairs. Subject to such provision, the
Trust Guarantee Trustee is under no obligation to exercise any of the powers
vested in it by the Trust Guarantee at the request of any holder of Trust
Preferred Securities unless it is offered reasonable indemnity against the
costs, expenses and liabilities that might be incurred thereby.
 
                                       33

GOVERNING LAW
 
    The Guarantee will be governed by, and construed in accordance with, the
internal laws of the State of New York.
 
              DESCRIPTION OF THE PARTNERSHIP PREFERRED SECURITIES
 
GENERAL
 
    All of the partnership interests in the Partnership, other than the
Partnership Preferred Securities acquired by the Trust, are owned directly by
the Company. Initially, the Company will be the sole General Partner of the
Partnership. The Limited Partnership Agreement authorizes and creates the
Partnership Preferred Securities, which represent limited partner interests in
the Partnership. The limited partner interests represented by the Partnership
Preferred Securities will have a preference with respect to distributions and
amounts payable on redemption or liquidation over the General Partner's interest
in the Partnership. Except as otherwise described herein or provided in the
Limited Partnership Agreement, the Limited Partnership Agreement does not permit
the issuance of any additional partnership interests, or the incurrence of any
indebtedness by the Partnership.
 
    The summary of certain material terms and provisions of the Partnership
Preferred Securities set forth below does not purport to be complete and is
subject to, and qualified in its entirety by reference to, the Limited
Partnership Agreement, which is filed as an exhibit to the Registration
Statement of which this Prospectus is a part, and the Partnership Act.
 
DISTRIBUTIONS
 
    Holders of Partnership Preferred Securities will be entitled to receive
cumulative cash distributions, if, as and when declared by the General Partner
in its sole discretion out of assets of the Partnership legally available for
payment. The distributions payable on each Partnership Preferred Security will
be fixed at a rate per annum of 7% of the stated liquidation preference of $25
per Partnership Preferred Security. Distributions not paid on the scheduled
payment date will accumulate and compound quarterly at the rate per annum equal
to 7%. The amount of distributions payable for any period will be computed on
the basis of a 360-day year of twelve 30-day months.
 
    Distributions on the Partnership Preferred Securities will be payable
quarterly in arrears on March 30, June 30, September 30 and December 30 of each
year, commencing March 30, 1998. If distributions are not declared and paid when
scheduled, the accumulated distributions shall be paid to the holders of record
of Partnership Preferred Securities as they appear on the books and records of
the Partnership on the record date with respect to the payment date for the
Partnership Preferred Securities.
 
    The Partnership's earnings available for distribution to the holders of the
Partnership Preferred Securities will be limited to payments made on the
Affiliate Investment Instruments and Investment Guarantees and payments on
Eligible Debt Securities in which the Partnership has invested from time to
time. See "-- Partnership Investments". To the extent that the issuers (and,
where applicable, the Company, as guarantor) of the securities in which the
Partnership invests fail to make any payment in respect of such securities (or,
if applicable, such guarantees), the Partnership will not have sufficient funds
to pay and will not declare or pay distributions on the Partnership Preferred
Securities, in which event the Partnership Guarantee will not apply to such
distributions until the Partnership has sufficient funds available therefor. See
"Description of the Partnership Guarantee". In addition, distributions on the
Partnership Preferred Securities may be declared and paid only as determined in
the sole discretion of the General Partner of the Partnership. If the
Partnership fails to declare and pay distributions on the Partnership Preferred
Securities out of funds legally available for distribution, the Trust will not
have sufficient funds to make distributions on the Trust Preferred Securities,
in which event the Trust Guarantee will not apply to such distributions until
the Trust has sufficient funds available therefor. In addition, as described
under "Risk Factors -- Insufficient Income or Assets Available to Partnership",
the Partnership
 
                                       34
<PAGE>
may not have sufficient funds to pay current or liquidating distributions on the
Partnership Preferred Securities if (i) at any time that the Partnership is
receiving current payments in respect of the securities held by the Partnership
(including the Debentures), the General Partner, in its sole discretion, does
not declare distributions on the Partnership Preferred Securities and the
Partnership receives insufficient amounts to pay the additional compounded
distributions that will accumulate in respect of the Partnership Preferred
Securities, (ii) the Partnership reinvests the proceeds received in respect of
the Debentures upon their retirement or at their maturities in Affiliate
Investment Instruments that do not generate income in an amount that is
sufficient to pay full distributions in respect of the Partnership Preferred
Securities or (iii) the Partnership invests in debt securities of Investment
Affiliates that are not guaranteed by the Company and that cannot be liquidated
by the Partnership for an amount sufficient to pay such distributions in full.
 
    Distributions on the Partnership Preferred Securities will be payable to the
holders thereof as they appear on the books and records of the Partnership on
the relevant record dates, which, as long as the Trust Preferred Securities
remain (or, in the event that the Trust is liquidated in connection with a Trust
Special Event, as long as the Partnership Preferred Securities remain) in
book-entry only form, will be one Business Day prior to the relevant payment
dates. In the event the Trust Preferred Securities (or in the event that the
Trust is liquidated in connection with a Trust Special Event, the Partnership
Preferred Securities) shall not continue to remain in book-entry only form, the
relevant record dates shall be the 15th day of the month of the relevant payment
dates. In the event that any date on which distributions are payable on the
Partnership Preferred Securities is not a Business Day, then payment of the
distribution payable on such date will be made on the next succeeding day that
is a Business Day (and without any interest or other payment in respect of any
such delay) except that, if such Business Day is in the next succeeding calendar
year, such payment shall be made on the immediately preceding Business Day, in
each case with the same force and effect as if made on such date.
 
PARTNERSHIP ENFORCEMENT EVENTS
 
    If one or more of the following events shall occur and be continuing (each a
"Partnership Enforcement Event"): (i) arrearages on distributions on the
Partnership Preferred Securities shall exist for six consecutive quarterly
distribution periods, (ii) the Company is in default on any of its obligations
under the Partnership Guarantee or any Investment Guarantee or (iii) an
Investment Event of Default occurs and is continuing on any Affiliate Investment
Instrument, then the Property Trustee, for so long as the Partnership Preferred
Securities are held by the Property Trustee, will have the right, or holders of
the Partnership Preferred Securities will be entitled by the vote of a majority
in aggregate liquidation preference of such holders (a) under the Limited
Partnership Agreement to enforce the terms of the Partnership Preferred
Securities, including the right to appoint and authorize a special
representative of the Partnership and the limited partners (a "Special
Representative") to enforce (1) the Partnership's creditors' rights and other
rights with respect to the Affiliate Investment Instruments and the Investment
Guarantees, (2) the rights of the holders of the Partnership Preferred
Securities under the Partnership Guarantee and (3) the rights of the holders of
the Partnership Preferred Securities to receive distributions (only if and to
the extent declared out of funds legally available therefor) on the Partnership
Preferred Securities, and (b) under the Partnership Guarantee to enforce the
terms of the Partnership Guarantee, including the right to enforce the covenant
restricting certain payments by the Company and Finance Subsidiaries.
 
    If the Special Representative fails to enforce its rights under the
Affiliate Investment Instruments after a holder of Partnership Preferred
Securities has made a written request, such holder of record of Partnership
Preferred Securities may directly institute a legal proceeding against the
Company to enforce the rights of the Special Representative and the Partnership
under the Affiliate Investment Instruments without first instituting any legal
proceeding against the Special Representative, the Partnership or any other
person or entity. In any event, if a Partnership Enforcement Event has occurred
and is continuing and such event is attributable to the failure of an Investment
Affiliate to make any required payment when due on any Affiliate Investment
Instrument, then a holder of Partnership Preferred Securities may on
 
                                       35
<PAGE>
behalf of the Partnership directly institute a proceeding against such
Investment Affiliate with respect to such Affiliate Investment Instrument for
enforcement of payment. A holder of Partnership Preferred Securities may also
bring a direct action against the Company to enforce such holder's right under
the Partnership Guarantee. See "Description of the Partnership Guarantee --
Events of Default; Enforcement of Partnership Guarantee".
 
    Under no circumstances, however, shall the Special Representative have
authority to cause the General Partner to declare distributions on the
Partnership Preferred Securities. As a result, although the Special
Representative may be able to enforce the Partnership's creditors' rights to
accelerate and receive payments in respect of the Affiliate Investment
Instruments and the Investment Guarantees, the Partnership would be entitled to
reinvest such payments in additional Affiliate Investment Instruments, subject
to satisfying the reinvestment criteria described under "-- Partnership
Investments", and Eligible Debt Securities, rather than declaring and making
distributions on the Partnership Preferred Securities. The Special
Representative shall not, by virtue of acting in such capacity, be admitted as a
general partner in the Partnership or otherwise be deemed to be a general
partner in the Partnership and shall have no liability for the debts,
obligations or liabilities of the Partnership.
 
PARTNERSHIP INVESTMENTS
 
    Approximately 99% of the proceeds from the issuance of the Partnership
Preferred Securities and the General Partner's contemporaneous capital
contribution (the "Initial Partnership Proceeds") will be used by the
Partnership to purchase the Debentures and the remaining 1% of the Initial
Partnership Proceeds will be used to purchase Eligible Debt Securities. The
purchase of the Debentures by the Partnership will occur contemporaneously with
the issuance of the Partnership Preferred Securities.
 
    The initial Affiliate Investment Instruments purchased by the Partnership
will consist of two or more debt instruments (the "Debentures"). The Company
anticipates that approximately 85% of the Initial Partnership Proceeds will be
used to purchase a Debenture of the Company (the "Company Debenture"), and
approximately 14% of the Initial Partnership Proceeds will be used to purchase
Debentures of one or more eligible controlled affiliates of the Company (the
"Affiliate Debentures"). Each Debenture is expected to have a term of 20 years
and to provide for interest payable on March 30, June 30, September 30 and
December 30 of each year, commencing March 30, 1998, at market rates for such
Debentures. The Debentures will be general unsecured debt obligations of the
relevant issuer, except that the Company Debenture will rank subordinate and
junior to all Senior Indebtedness of the Company.
 
    The payment of interest on each of the Debentures may be deferred at any
time, and from time to time, by the relevant issuer for a period not exceeding
six consecutive quarters. If an issuer were to so defer the payment of interest,
interest would continue to accrue and compound at the stated interest rate on
such Debenture. The Debentures will contain covenants appropriate for unsecured
debt securities issued or guaranteed by similar borrowers pursuant to a public
offering or private placement under Rule 144A of the Securities Act of a
comparable debt security, including a limitation on consolidation, merger and
sale or conveyance of assets. The Debentures will contain redemption provisions
that correspond to the redemption provisions applicable to the Partnership
Preferred Securities, including an option to redeem the Debentures by the
relevant issuer, in whole or in part, from time to time, on or after March 30,
2008, and following the occurrence of a Partnership Special Event, in each case,
in the same manner described under "-- Optional Redemption" and "-- Partnership
Special Event Redemption". The Debentures, and any other Affiliate Investment
Instruments that are debt instruments acquired by the Partnership in the future,
will also contain customary events of default (the "Investment Events of
Default"), including events of default for defaults in payments on such
securities when due (provided that no default shall occur upon a valid deferral
of an interest payment by an issuer), defaults in the performance of the
relevant issuer's obligations under its Debenture or Affiliate Investment
Instruments, as the case may be, and certain bankruptcy, insolvency or
reorganization events (subject to customary exceptions and grace periods).
 
                                       36
<PAGE>
    The payment of interest and principal when due and other payment terms of
the Debentures (other than the Company Debenture), will be guaranteed to the
extent described herein (each, an "Investment Guarantee") by the Company for the
benefit of the holders of Partnership Preferred Securities. See "-- Investment
Guarantees".
 
    Approximately 1% of the Initial Partnership Proceeds will be invested in
Eligible Debt Securities. "Eligible Debt Securities" means cash or book-entry
securities, negotiable instruments, or other securities of entities not
affiliated with the Company which evidence any of the following: (a) any
security issued or guaranteed as to principal or interest by the United States,
or by a person controlled or supervised by and acting as an instrumentality of
the Government of the United States pursuant to authority granted by the
Congress of the United States, or any certificate of deposit for any of the
foregoing; (b) commercial paper issued pursuant to Section 3(a)(3) of the
Securities Act and having, at the time of the investment or contractual
commitment to invest therein, a rating from each of Standard & Poor's Ratings
Services, a division of the McGraw-Hill Companies, Inc. ("S&P") and Moody's
Investors Service, Inc. ("Moody's") in the highest investment rating category
granted by such rating agency and having a maturity not in excess of nine
months; (c) demand deposits, time deposits and certificates of deposit which are
fully insured by the Federal Deposit Insurance Corporation ("FDIC"); (d)
repurchase obligations with respect to any security that is a direct obligation
of, or fully guaranteed by, the Government of the United States of America or
any agency or instrumentality thereof, the obligations of which are backed by
the full faith and credit of the United States of America, in either case
entered into with a depository institution or trust company which is an Eligible
Institution (as defined herein) and the deposits of which are insured by the
FDIC; and (e) any other security which is identified as a permitted investment
of a finance subsidiary pursuant to Rule 3a-5 under the 1940 Act at the time it
is acquired by the Partnership.
 
    "Eligible Institution" means (a) a depository institution organized under
the laws of the United States or any one of the states thereof or the District
of Columbia (or any domestic branch of a foreign bank), (1) (i) which has either
(A) a long-term unsecured debt rating of AA or better by S&P and Aa or better by
Moody's or (B) a short-term unsecured debt rating or a certificate of deposit
rating of A-1+ by S&P and P-1 by Moody's and (ii) whose deposits are insured by
the FDIC or (2) (i) the parent of which has a long-term or short-term unsecured
debt rating which signifies investment grade and (ii) whose deposits are insured
by the FDIC.
 
    The Partnership may, from time to time and subject to the restrictions
described below, reinvest payments received with respect to the Affiliate
Investment Instruments (including the Debentures) and the Eligible Debt
Securities in additional Affiliate Investment Instruments and Eligible Debt
Securities. As of the date of this Prospectus, the Company, as the General
Partner, does not intend to cause the Partnership to reinvest regularly
scheduled, periodic payments of interest or dividends received by the
Partnership in the manner described below, although there can be no assurance
that the General Partner's intention in respect of such reinvestments will not
change in the future.
 
    The fairness of specific terms of all Affiliate Investment Instruments
(including the Debentures) will be passed upon by a nationally recognized
accounting firm, bank or investment banking firm that does not (and whose
directors, officers, employees and affiliates do not) have a direct or indirect
material equity interest in the Company or any of its subsidiaries (the
"Independent Financial Advisor").
 
    The Partnership may reinvest in additional Affiliate Investment Instruments
only if certain procedures and criteria are satisfied with respect to each such
Affiliate Investment Instrument, including the satisfaction of the following
conditions: (i) the Partnership did not hold debt securities of the issuer of
the proposed Affiliate Investment Instrument within the three-year period ending
on the date of such proposed investment; (ii) there was never a default on any
debt obligation of, or arrearages of dividends on preferred stock issued by, the
issuer of the proposed Affiliate Investment Instrument that was previously or is
currently owned by the Partnership; (iii) the applicable terms and provisions
with respect to the proposed Affiliate Investment Instrument have been
determined by the Independent Financial Advisor to be at least as favorable as
terms which could be obtained by the Partnership in a public offering or private
 
                                       37
<PAGE>
placement under Rule 144A of the Securities Act of a comparable security issued
by the relevant Investment Affiliate and guarantees, if any, included therein;
and (iv) the requesting Investment Affiliate shall not be deemed to be an
investment company by reason of Section 3(a) or 3(b) of the 1940 Act or is
otherwise an eligible recipient of funds directly or indirectly from the Trust
pursuant to an order issued by the Commission. The term "Investment Affiliate"
means the Company or any corporation, partnership, limited liability company or
other entity (other than the Partnership or the Trust) that is controlled by the
Company. If the Partnership is unable to reinvest payments and proceeds from
Affiliate Investment Instruments in additional Affiliate Investment Instruments
meeting the above criteria, the Partnership may only invest such funds in
Eligible Debt Securities (subject to restrictions of applicable law, including
the 1940 Act).
 
INVESTMENT GUARANTEES
 
    GENERAL
 
    The Company will agree to execute and deliver an Investment Guarantee, on a
subordinated basis, for the benefit of the holders of Partnership Preferred
Securities with respect to each Debenture issued by an Investment Affiliate
(other than the Company Debenture) to the extent set forth below. The Investment
Guarantees shall be enforceable regardless of any defense, right of set-off or
counterclaim that the Company may have or assert. The Investment Guarantees will
be full and unconditional guarantees, to the extent set forth therein, with
respect to the applicable Debentures from the time of issuance. To the extent
that, as described above, the Partnership invests in additional Affiliate
Investment Instruments, the determination as to whether such Affiliate
Investment Instrument will contain an Investment Guarantee will be made at the
date of its issuance and will be based, among other things, upon its approval by
the Independent Financial Advisor in accordance with the reinvestment criteria
described above.
 
    The Investment Guarantees will constitute guarantees of payment and not of
collection (that is, the guaranteed party may directly institute a legal
proceeding against the Company to enforce its rights under the applicable
Investment Guarantee without instituting a legal proceeding against any other
person or entity). If no Special Representative has been appointed to enforce
any Investment Guarantee, the General Partner has the right to enforce such
Investment Guarantee on behalf of the holders of the Partnership Preferred
Securities. The holders of not less than a majority in aggregate liquidation
preference of the Partnership Preferred Securities have the right to direct the
time, method and place of conducting any proceeding for any remedy available in
respect of any Investment Guarantee, including the giving of directions to the
General Partner or the Special Representative, as the case may be. If the
General Partner or the Special Representative fails to enforce any Investment
Guarantee as above provided, any holder of Trust Preferred Securities may
institute its own legal proceeding to enforce such Investment Guarantee. No
Investment Guarantee will be discharged except by payment in full of all amounts
guaranteed by such Investment Guarantee (without duplication of amounts
theretofore paid by the relevant Investment Affiliate).
 
    AMENDMENTS AND ASSIGNMENT
 
    Except with respect to any changes that do not adversely affect the rights
of holders of Partnership Preferred Securities (in which case no consent will be
required), the Investment Guarantees may be amended only with the prior approval
of the holders of not less than a majority in liquidation preference of the
outstanding Partnership Preferred Securities, PROVIDED that for so long as the
Property Trustee of the Trust is the holder of the Partnership Preferred
Securities, such amendment will not be effective without the prior written
approval of a majority in liquidation amount of the outstanding Trust Preferred
Securities. All guarantees and agreements contained in the Investment Guarantees
shall bind the successors, assigns, receivers, trustees and representatives of
the Company and shall inure to the benefit of the holders of Partnership
Preferred Securities. Except in connection with any permitted merger or
consolidation of the Company with or into another entity or any permitted sale,
transfer or lease of the Company's
 
                                       38
<PAGE>
assets to another entity in which the surviving corporation (if other than the
Company) assumes the Company's obligations under the Investment Guarantees, the
Company may not assign its rights or delegate its obligations under the
Investment Guarantees without the prior approval of the holders of at least a
majority of the aggregate stated liquidation preference of the Partnership
Preferred Securities then outstanding.
 
    STATUS OF THE INVESTMENT GUARANTEES
 
    The Company's obligations under the Investment Guarantees will constitute
unsecured obligations of the Company and will rank subordinate and junior in
right of payment to all other liabilities of the Company and will rank PARI
PASSU with the most senior preferred stock, if any, issued from time to time by
the Company, with similar guarantees issued by the Company in connection with
the $275,000,000 aggregate liquidation amount of 7 3/4% Trust Originated
Preferred Securities issued by Merrill Lynch Preferred Capital Trust I and the
$300,000,000 aggregate liquidation amount of 8% Trust Originated Preferred
Securities issued by Merrill Lynch Preferred Capital Trust II, and with any
guarantee now or hereafter entered into by the Company in respect of any
preferred stock of any other Finance Subsidiary. Accordingly, the rights of the
holders of the Debentures to receive payments under the Investment Guarantees
will be subject to the rights of the holders of any obligations that are senior
in priority to the obligations under the Investment Guarantees. Furthermore, the
holders of obligations of the Company that are senior to the obligations under
the Investment Guarantees (including, but not limited to, obligations
constituting Senior Indebtedness) will be entitled to the same rights upon
payment default or dissolution, liquidation and reorganization in respect of the
Investment Guarantees that inure to the holders of Senior Indebtedness as
against the holders of the Company Debenture. The terms of the Debentures
provide that each holder of Debentures, by acceptance thereof, agrees to the
subordination provisions and other terms of the Investment Guarantees.
 
    GOVERNING LAW
 
    The Investment Guarantees will be governed by and construed in accordance
with the internal laws of the State of New York.
 
OPTIONAL REDEMPTION
 
    The Partnership Preferred Securities are redeemable, at the option of the
General Partner, in whole or in part, from time to time, on or after March 30,
2008, upon not less than 30 nor more than 60 days notice, at an amount per
Partnership Preferred Security equal to $25 plus accumulated and unpaid
distributions thereon. If the Partnership redeems Partnership Preferred
Securities in accordance with the terms thereof, Trust Securities will be
mandatorily redeemed at the Redemption Price. If a partial redemption would
result in the delisting of the Trust Preferred Securities (or, if the Trust is
liquidated in connection with a Trust Special Event, or if a partial redemption
would result in the delisting of the Partnership Preferred Securities), the
Partnership may only redeem the Partnership Preferred Securities in whole.
 
PARTNERSHIP SPECIAL EVENT REDEMPTION
 
    If, at any time, a Partnership Tax Event or a Partnership Investment Company
Event (each as hereinafter defined, and each a "Partnership Special Event")
shall occur and be continuing, the General Partner shall, within 90 days
following the occurrence of such Partnership Special Event, elect to either (i)
redeem the Partnership Preferred Securities in whole (but not in part), upon not
less than 30 or more than 60 days notice at the Redemption Price, PROVIDED that,
if at the time there is available to the Partnership the opportunity to
eliminate, within such 90-day period, the Partnership Special Event by taking
some ministerial action, such as filing a form or making an election, or
pursuing some other similar reasonable such measure that in the sole judgment of
the Company has or will cause no adverse effect on the Partnership, the Trust or
the Company, the General Partner will pursue such measure in lieu of redemption;
or (ii) cause the Partnership Preferred Securities to remain outstanding,
PROVIDED that in the case of this clause (ii), the General Partner shall pay any
and all costs and expenses incurred by or payable by the Partnership
attributable to the Partnership Special Event.
 
                                       39
<PAGE>
    "Partnership Tax Event" means that the General Partner shall have requested
and received an opinion of nationally recognized independent tax counsel
experienced in such matters to the effect that there has been a Tax Action which
affects any of the events described in (i) through (iii) below and that there is
more than an insubstantial risk that (i) the Partnership is, or will be, subject
to United States federal income tax with respect to income accrued or received
on the Affiliate Investment Instruments or the Eligible Debt Securities, (ii)
the Partnership is, or will be, subject to more than a DE MINIMIS amount of
other taxes, duties or other governmental charges or (iii) interest payable by
an Investment Affiliate with respect to the Debenture issued by such Investment
Affiliate to the Partnership is not, or will not be, deductible by such
Investment Affiliate for United States federal income tax purposes.
 
    "Partnership Investment Company Event" means that the General Partner shall
have requested and received an opinion of nationally recognized independent
legal counsel experienced in such matters to the effect that as a result of the
occurrence on or after the date hereof of a Change in 1940 Act Law, the
Partnership is or will be considered an "investment company" which is required
to be registered under the 1940 Act.
 
REDEMPTION PROCEDURES
 
    The Partnership may not redeem fewer than all the outstanding Partnership
Preferred Securities unless all accumulated and unpaid distributions have been
paid on all Partnership Preferred Securities for all quarterly distribution
periods terminating on or prior to the date of redemption.
 
    If the Partnership gives a notice of redemption in respect of Partnership
Preferred Securities (which notice will be irrevocable) then, by 12:00 noon, New
York City time, on the redemption date, the Partnership (i) if the Partnership
Preferred Securities are in book-entry form with DTC, will deposit irrevocably
with DTC funds sufficient to pay the applicable Redemption Price and will give
DTC irrevocable instructions and authority to pay the Redemption Price in
respect of the Partnership Preferred Securities held through DTC in global form
or (ii) if the Partnership Preferred Securities are held in certificated form,
will deposit with the paying agent for the Partnership Preferred Securities
funds sufficient to pay such amount in respect of any Partnership Preferred
Securities in certificated form and will give such paying agent irrevocable
instructions and authority to pay such amounts to the holders of Partnership
Preferred Securities upon surrender of their certificates. See "Description of
the Trust Preferred Securities -- Book-Entry Only Issuance -- The Depository
Trust Company".
 
    If notice of redemption shall have been given and funds deposited as
required, then upon the date of such deposit, all rights of holders of such
Partnership Preferred Securities so called for redemption will cease, except the
right of the holders of such Partnership Preferred Securities to receive the
Redemption Price, but without interest on such Redemption Price. In the event
that any date fixed for redemption of Partnership Preferred Securities is not a
Business Day, then payment of the Redemption Price payable on such date will be
made on the next succeeding day that is a Business Day (and without any interest
or other payment in respect of any such delay) except that, if such Business Day
falls in the next calendar year, such payment will be made on the immediately
preceding Business Day, in each case with the same force and effect as if made
on such date fixed for redemption. In the event that payment of the Redemption
Price in respect of Partnership Preferred Securities is improperly withheld or
refused and not paid either by the Partnership or by the Company pursuant to the
Partnership Guarantee described under "Description of the Partnership
Guarantee," distributions on such Partnership Preferred Securities will continue
to accumulate, from the original redemption date to the date of payment.
 
    Subject to the foregoing and applicable law (including, without limitation,
United States federal securities laws), the Company or any of its subsidiaries
may at any time and from time to time purchase outstanding Partnership Preferred
Securities by tender, in the open market or by private agreement.

LIQUIDATION DISTRIBUTION UPON DISSOLUTION
 
    In the event of any voluntary or involuntary dissolution, winding-up or
termination of the Partnership, the holders of the Partnership Preferred
Securities at the time will be entitled to receive out of the assets of the
Partnership available for distribution to partners after satisfaction of
liabilities of creditors as required by the Partnership Act, before any
distribution of assets is made to the General Partner, an amount equal to, in
the case of holders of Partnership Preferred Securities, the aggregate of the
stated liquidation preference of $25 per Partnership Preferred Security plus
accumulated and unpaid distributions thereon to the date of payment (such amount
being the "Partnership Liquidation Distribution").
 
    Pursuant to the Limited Partnership Agreement, the Partnership shall be
dissolved and its affairs shall be wound up: (i) upon the bankruptcy of the
General Partner, (ii) upon the assignment by the General Partner of its entire
interest in the Partnership when the assignee is not admitted to the Partnership
as a general partner of the Partnership in accordance with the Limited
Partnership Agreement, or the filing of a certificate of dissolution or its
equivalent with respect to the General Partner, or the revocation of the General
Partner's charter and the expiration of 90 days after the date of notice to the
General Partner of revocation without a reinstatement of its charter, or if any
other event occurs that causes the General Partner to cease to be a general
partner of the Partnership under the Partnership Act, unless the business of the
Partnership is continued in accordance with the Partnership Act, (iii) if the
Partnership has redeemed or otherwise purchased all the Partnership Preferred
Securities, (iv) upon the entry of a decree of judicial dissolution or (v) upon
the written consent of all partners of the Partnership.
 
VOTING RIGHTS
 
    Except as provided below and under "Description of the Partnership Guarantee
- -- Amendments and Assignment" and as otherwise required by law and the Limited
Partnership Agreement, the holders of the Partnership Preferred Securities will
have no voting rights.
 
    Not later than 30 days after any Partnership Enforcement Event occurs, the
General Partner will convene a meeting for the purpose of appointing a Special
Representative. If the General Partner fails to convene such meeting within such
30-day period, the holders of 10% in liquidation preference of the outstanding
Partnership Preferred Securities will be entitled to convene such meeting. The
provisions of the Limited Partnership Agreement relating to the convening and
conduct of the meetings of the partners will apply with respect to any such
meeting. In the event that, at any such meeting, holders of less than a majority
in aggregate liquidation preference of Partnership Preferred Securities entitled
to vote for the appointment of a Special Representative vote for such
appointment, no Special Representative shall be appointed. Any Special
Representative appointed shall cease to be a Special Representative of the
Partnership and the limited partners if (1) the Partnership (or the Company
pursuant to the Partnership Guarantee) shall have paid in full all accumulated
and unpaid distributions on the Partnership Preferred Securities, (2) such
Investment Event of Default, as the case may be, shall have been cured, and (3)
the Company is in compliance with all its obligations under the Partnership
Guarantee and the Company, in its capacity as the General Partner, shall
continue the business of the Partnership without dissolution. Notwithstanding
the appointment of any such Special Representative, the Company shall continue
as General Partner and shall retain all rights under the Limited Partnership
Agreement, including the right to declare, in its sole discretion, the payment
of distributions on the Partnership Preferred Securities for which the failure
of such declaration would not constitute a default under the Limited Partnership
Agreement.
 
    If any proposed amendment to the Limited Partnership Agreement provides for,
or the General Partner otherwise proposes to effect, (i) any action that would
adversely affect the powers, preferences or special rights of the Partnership
Preferred Securities, whether by way of amendment to the Limited Partnership
Agreement or otherwise (including, without limitation, the authorization or
issuance of any
 
                                       41
<PAGE>
limited partner interests in the Partnership ranking, as to participation in the
profits or distributions or in the assets of the Partnership, senior to the
Partnership Preferred Securities), or (ii) the dissolution, winding-up or
termination of the Partnership, other than (x) in connection with the occurrence
of a Partnership Special Event or (y) as described under "Merger, Consolidation
or Amalgamation of the Partnership" below, then the holders of outstanding
Partnership Preferred Securities will be entitled to vote on such amendment or
proposal of the General Partner (but not on any other amendment or proposal) as
a class, and such amendment or proposal shall not be effective except with the
approval of the holders of a majority in liquidation preference of such
outstanding Partnership Preferred Securities having a right to vote on the
matter; PROVIDED, HOWEVER, that if the Property Trustee on behalf of the Trust
is the holder of the Partnership Preferred Securities, any such amendment or
proposal not excepted by clauses (x) and (y) above shall not be effective
without the prior or concurrent approval of the holders of a majority in
liquidation amount of the outstanding Trust Preferred Securities having a right
to vote on such matters.
 
    The General Partner shall not (i) direct the time, method and place of
conducting any proceeding for any remedy available, (ii) waive any Investment
Event of Default that is waivable under the Affiliate Investment Instruments,
(iii) exercise any right to rescind or annul a declaration that the principal of
any Affiliate Investment Instruments shall be due and payable, (iv) waive the
breach of the covenant by the Company to restrict certain payments by the
Company, or (v) consent to any amendment, modification or termination of any
Affiliate Investment Instrument, where such consent shall be required from the
investor, without, in each case, obtaining the prior approval of the holders of
at least a majority in liquidation preference of the Partnership Preferred
Securities; PROVIDED, HOWEVER, that if the Property Trustee on behalf of the
Trust is the holder of the Partnership Preferred Securities, such waiver,
consent or amendment or other action shall not be effective without the prior or
concurrent approval of at least a majority in liquidation amount of the
outstanding Trust Preferred Securities having a right to vote on such matters.
The General Partner shall not revoke any action previously authorized or
approved by a vote of the holders of the Partnership Preferred Securities
without the approval of such revocation by a majority in liquidation preference
of the outstanding Partnership Preferred Securities. The General Partner shall
notify all holders of the Partnership Preferred Securities of any notice of an
Investment Event of Default received with respect to any Affiliate Investment
Instrument.
 
    Any required approval of holders of Partnership Preferred Securities may be
given at a separate meeting of holders of Partnership Preferred Securities
convened for such purpose, at a meeting of all of the partners in the
Partnership or pursuant to written consent. The Partnership will cause a notice
of any meeting at which holders of Partnership Preferred Securities are entitled
to vote, or of any matter upon which action by written consent of such holders
is to be taken, to be mailed to each holder of record of Partnership Preferred
Securities. Each such notice will include a statement setting forth (i) the date
of such meeting or the date by which such action is to be taken, (ii) a
description of any resolution proposed for adoption at such meeting on which
such holders are entitled to vote or of such matters upon which written consent
is sought and (iii) instruction for the delivery of proxies or consents.
 
    No vote or consent of the holders of Partnership Preferred Securities will
be required for the Partnership to redeem and cancel Partnership Preferred
Securities in accordance with the Limited Partnership Agreement.
 
    Notwithstanding that holders of Partnership Preferred Securities are
entitled to vote or consent under any of the circumstances described above, any
of the Partnership Preferred Securities at such time that are beneficially owned
by the Company or by any entity directly or indirectly controlled by, or under
direct or indirect common control with, the Company, except for Partnership
Preferred Securities purchased or acquired by the Company or its affiliates in
connection with transactions effected by or for the account of customers of the
Company or any of its subsidiaries or in connection with the distribution or
trading of such Partnership Preferred Securities; shall not be entitled to vote
or consent and shall, for purposes of such vote or consent, be treated as if
they were not outstanding, PROVIDED, HOWEVER, that persons (other than
 
                                       42
<PAGE>
affiliates of the Company) to whom the Company or any of its subsidiaries have
pledged Partnership Preferred Securities may vote or consent with respect to
such pledged Partnership Preferred Securities pursuant to the terms of such
pledge.
 
    Holders of the Partnership Preferred Securities will have no rights to
remove or replace the General Partner.
 
MERGER, CONSOLIDATION OR AMALGAMATION OF THE PARTNERSHIP
 
    The Partnership may not consolidate, amalgamate, merge with or into, or be
replaced by, or convey, transfer or lease its properties and assets
substantially as an entirety to, any corporation or other body, except as
described below. The Partnership may, without the consent of the holders of the
Partnership Preferred Securities, consolidate, amalgamate, merge with or into,
or be replaced by a limited partnership, limited liability company or trust
organized as such under the laws of any state of the United States of America,
provided that (i) such successor entity either (x) expressly assumes all of the
obligations of the Partnership under the Partnership Preferred Securities or (y)
substitutes for the Partnership Preferred Securities other securities having
substantially the same terms as the Partnership Preferred Securities (the
"Partnership Successor Securities") so long as the Partnership Successor
Securities are not junior to any other equity securities of the successor
entity, with respect to participation in the profits and distributions, and in
the assets, of the successor entity, (ii) the Investment Affiliates expressly
acknowledge such successor entity as the holder of the Affiliate Investment
Instruments, (iii) the Partnership Preferred Securities or any Partnership
Successor Securities are listed, or any Partnership Successor Securities will be
listed upon notification of issuance, on any national securities exchange or
other organization on which the Partnership Preferred Securities, if so listed,
are then listed, (iv) such merger, consolidation, amalgamation or replacement
does not cause the Trust Preferred Securities (or, in the event that the Trust
is liquidated in connection with a Trust Special Event, the Partnership
Preferred Securities (including any Partnership Successor Securities)) to be
downgraded by any nationally recognized statistical rating organization, (v)
such merger, consolidation, amalgamation or replacement does not adversely
affect the powers, preferences and other special rights of the holders of the
Trust Preferred Securities or Partnership Preferred Securities (including any
Partnership Successor Securities) in any material respect (other than, in the
case of the Partnership Preferred Securities, with respect to any dilution of
the holders' interest in the new resulting entity), (vi) such successor entity
has a purpose substantially identical to that of the Partnership, (vii) prior to
such merger, consolidation, amalgamation or replacement, the Company has
received an opinion of nationally recognized independent counsel to the
Partnership experienced in such matters to the effect that (A) such successor
entity will be treated as a partnership for United States federal income tax
purposes, (B) such merger, consolidation, amalgamation or replacement would not
cause the Trust to be classified as an association taxable as a corporation for
United States federal income tax purposes, (C) following such merger,
consolidation, amalgamation or replacement, the Company and such successor
entity will be in compliance with the 1940 Act without registering thereunder as
an investment company, and (D) such merger, consolidation, amalgamation or
replacement will not adversely affect the limited liability of the holders of
the Partnership Preferred Securities and (viii) the Company guarantees the
obligations of such successor entity under the Partnership Successor Securities
at least to the extent provided by the Partnership Guarantee.
 
BOOK-ENTRY AND SETTLEMENT
 
    If the Partnership Preferred Securities are distributed to holders of Trust
Preferred Securities in connection with the involuntary or voluntary
dissolution, winding-up or liquidation of the Trust as a result of the
occurrence of a Trust Special Event, the Partnership Preferred Securities will
be issued in the form of one or more global certificates (each a "Global
Partnership Security") registered in the name of DTC as the depository or its
nominee. For a description of DTC and the specific terms of the Depository
arrangements, see "Description of the Trust Preferred Securities -- Book-Entry
Only Issuance -- The
 
                                       43
<PAGE>
Depository Trust Company". As of the date of this Prospectus, the description
therein of DTC's book-entry system and DTC's practices as they relate to
purchases, transfers, notices and payments with respect to the Trust Preferred
Securities apply in all material respects to any Partnership Preferred
Securities represented by one or more Global Partnership Securities.
 
REGISTRAR, TRANSFER AGENT AND PAYING AGENT
 
    The General Partner will act as registrar, transfer agent and paying agent
for the Partnership Preferred Securities for so long as the Partnership
Preferred Securities are held by the Trust or, if the Trust is liquidated in
connection with a Trust Special Event, for so long as the Partnership Preferred
Securities remain in book-entry only form. In the event the Partnership
Preferred Securities are distributed in connection with a Trust Special Event
and the book-entry system for the Partnership Preferred Securities is
discontinued, it is anticipated that The Chase Manhattan Bank or one of its
affiliates will act as registrar, transfer agent and paying agent for the
Partnership Preferred Securities.
 
    Registration of transfers of Partnership Preferred Securities will be
effected without charge by or on behalf of the Partnership, but upon payment
(with the giving of such indemnity as the Partnership or the General Partner may
require) in respect of any tax or other governmental charges that may be imposed
in relation to it.
 
    The Partnership will not be required to register or cause to be registered
the transfer of Partnership Preferred Securities after such Partnership
Preferred Securities have been called for redemption.
 
MISCELLANEOUS
 
    The General Partner is authorized and directed to conduct its affairs and to
operate the Partnership in such a way that (i) the Partnership will not be
deemed to be an "investment company" required to be registered under the 1940
Act or characterized as an association taxable as a corporation for United
States federal income tax purposes, (ii) the Affiliate Investment Instruments
will be treated as indebtedness of the issuer of such debt instruments for
United States federal income tax purposes and (iii) the Partnership will not be
treated as an association or as a "publicly traded partnership" (within the
meaning of Section 7704 of the Code) taxable as a corporation. In this
connection, the General Partner is authorized to take any action, not
inconsistent with applicable law, the certificate of limited partnership of the
Partnership or the Limited Partnership Agreement, that the General Partner
determines in its discretion to be necessary or desirable for such purposes as
long as such action does not adversely affect the interests of the holders of
the Partnership Preferred Securities.
 
                    DESCRIPTION OF THE PARTNERSHIP GUARANTEE
 
    Set forth below is a summary of information concerning the Partnership
Guarantee that will be executed and delivered by the Company for the benefit of
the holders from time to time of Partnership Preferred Securities. The summary
does not purport to be complete and is subject in all respects to the provisions
of, and is qualified in its entirety by reference to, the Partnership Guarantee,
which is filed as an exhibit to the Registration Statement of which this
Prospectus is a part. The General Partner will hold the Partnership Guarantee
for the benefit of the holders of the Partnership Preferred Securities.
 
GENERAL
 
    Pursuant to the Partnership Guarantee, the Company will irrevocably agree,
on a subordinated basis to the extent set forth therein, to pay in full to the
holders of the Partnership Preferred Securities (without duplication of amounts
theretofore paid by the Partnership), as and when due, regardless of any
defense, right of set-off or counterclaim that the Partnership may have or
assert, the following payments (the
 
                                       44
<PAGE>
"Partnership Guarantee Payments"): (i) any accumulated and unpaid distributions
that have theretofore been declared on the Partnership Preferred Securities out
of funds legally available therefor, (ii) the redemption price with respect to
any Partnership Preferred Securities called for redemption by the Partnership
out of funds legally available therefor, and (iii) upon a liquidation of the
Partnership, the lesser of (a) the aggregate of the liquidation preference and
all accumulated and unpaid distributions on the Partnership Preferred Securities
to the date of payment and (b) the amount of assets of the Partnership, after
satisfaction of all liabilities, remaining available for distribution to holders
of Partnership Preferred Securities in liquidation of the Partnership. The
Company's obligation to make a Partnership Guarantee Payment may be satisfied by
direct payment of the required amounts by the Company to the holders of
Partnership Preferred Securities or by causing the Partnership to pay such
amounts to such holders.
 
    The Partnership Guarantee will be a guarantee on a subordinated basis with
respect to the Partnership Preferred Securities from the time of issuance of
such Partnership Preferred Securities but will not apply to any payment of
distributions or Redemption Price, or to payments upon the dissolution,
winding-up or termination of the Trust, except to the extent the Partnership
shall have funds available therefor. If Investment Affiliates (including, where
applicable, the Company, as guarantor) of the Affiliate Investment Instruments
in which the Partnership invests fail to make any payment in respect of such
securities (or, if applicable, guarantees), the Partnership may not declare or
pay dividends on the Partnership Preferred Securities. In such event, holders of
the Partnership Preferred Securities would not be able to rely upon the
Partnership Guarantee for payment of such amounts. Instead, holders of the
Partnership Preferred Securities will have the remedies described herein under
"Description of the Partnership Preferred Securities -- Partnership Enforcement
Events," including the right to direct the General Partner or the Special
Representative, as the case may be, to enforce the covenant restricting certain
payments by the Company and Finance Subsidiaries. See "-- Covenants of the
Company" below.
 
    The Guarantees, when taken together with the Company Debenture and the
Company's obligations to pay all fees and expenses of the Trust and the
Partnership, constitute a guarantee to the extent set forth herein by the
Company of the distribution, redemption and liquidation payments payable to the
holders of the Trust Preferred Securities. The Guarantees do not apply, however,
to current distributions by the Partnership unless and until such distributions
are declared by the Partnership out of funds legally available for payment or to
liquidating distributions unless there are assets available for payment in the
Partnership, each as more fully described under "Risk Factors--Insufficient
Income or Assets Available to Partnership".
 
COVENANTS OF THE COMPANY
 
    The Company will covenant in the Partnership Guarantee that if (a) for any
distribution period, full distributions on a cumulative basis on any Partnership
Preferred Securities have not been paid or declared and set apart for payment,
(b) an Investment Event of Default by any Investment Affiliate in respect of any
Affiliate Investment Instrument has occurred and is continuing or (c) the
Company is in default of its obligations under the Trust Guarantee, the
Partnership Guarantee or any Investment Guarantee, then, during such period (i)
the Company shall not declare or pay dividends on, make distributions with
respect to, or redeem, purchase or acquire, or make a liquidation payment with
respect to, any of its capital stock or comparable equity interest (except for
(x) dividends or distributions in shares of, or options, warrants or rights to
subscribe for or purchase shares of, its capital stock, and conversions or
exchanges of common stock of one class into common stock of another class, (y)
redemptions or purchases of any rights pursuant to the Rights Agreement and the
issuance of preferred stock pursuant to such rights and (z) purchases or
acquisitions by the Company or its affiliates in connection with transactions
effected by or for the account of customers of the Company or any of its
subsidiaries or in connection with the distribution or trading of such capital
stock or comparable equity interest) and (ii) the Company shall not make, permit
any Finance Subsidiary to make, or make any payments that would enable any
Finance Subsidiary to make, any payment of any dividends on, any distribution
with respect to, or any redemption, purchase or other
 
                                       45
<PAGE>
acquisition of, or any liquidation payment with respect to, any preferred
security or comparable equity interest of any Finance Subsidiary.
 
EVENTS OF DEFAULT; ENFORCEMENT OF PARTNERSHIP GUARANTEE
 
    An event of default under the Partnership Guarantee will occur upon the
failure of the Company to perform any of its payment or other obligations
thereunder.
 
    The holders of a majority in liquidation amount of the Partnership Preferred
Securities have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Special Representative in respect of
the Partnership Guarantee or to direct the exercise of any trust or power
conferred upon the Special Representative under the Partnership Guarantee. If
the Special Representative fails to enforce its rights under the Partnership
Guarantee, after a holder of Partnership Preferred Securities has made a written
request, such holder of Partnership Preferred Securities may institute a legal
proceeding directly against the Company to enforce the Special Representative's
rights under the Partnership Guarantee without first instituting a legal
proceeding against the Partnership, the Special Representative or any other
person or entity. Notwithstanding the foregoing, if the Company has failed to
make a guarantee payment, a holder of Partnership Preferred Securities may
directly institute a proceeding against the Company for enforcement of the
Partnership Guarantee for such payment.
 
STATUS OF THE PARTNERSHIP GUARANTEE; SUBORDINATION
 
    The Partnership Guarantee will constitute an unsecured obligation of the
Company and will rank subordinate and junior in right of payment to all other
liabilities of the Company and will rank PARI PASSU with the most senior
preferred stock issued from time to time by the Company, with similar guarantees
issued by the Company in connection with the $275,000,000 aggregate liquidation
amount of 7 3/4% Trust Originated Preferred Securities issued by Merrill Lynch
Preferred Capital Trust I and the $300,000,000 aggregate liquidation amount of
8% Trust Originated Preferred Securities issued by Merrill Lynch Preferred
Capital Trust II, and with any guarantee now or hereafter entered into by the
Company in respect of any preferred stock of any other Finance Subsidiary.
Accordingly, the rights of the holders of Partnership Preferred Securities to
receive payments under the Partnership Guarantee will be subject to the rights
of the holders of any obligations of the Company that are senior in priority to
the obligations under the Partnership Guarantee. Furthermore, the holders of
obligations of the Company that are senior to the obligations under the
Partnership Guarantee (including, but not limited to, obligations constituting
Senior Indebtedness) will be entitled to the same rights upon payment default or
dissolution, liquidation and reorganization in respect of the Partnership
Guarantee that inure to the holders of Senior Indebtedness as against the
holders of the Company Debenture. The Limited Partnership Agreement provides
that each holder of Partnership Preferred Securities, by acceptance thereof,
agrees to the subordination provisions and other terms of the Partnership
Guarantee.
 
    The Partnership Guarantee will constitute a guarantee of payment and not of
collection (that is, the guaranteed party may directly institute a legal
proceeding against the Company to enforce its rights under the Partnership
Guarantee without instituting a legal proceeding against any other person or
entity).
 
    The Partnership Guarantee will be deposited with the General Partner to be
held for the benefit of the holders of the Partnership Preferred Securities. In
the event of the appointment of a Special Representative to, among other things,
enforce the Partnership Guarantee, the Special Representative may take
possession of the Partnership Guarantee for such purpose. If no Special
Representative has been appointed to enforce the Partnership Guarantee, the
General Partner has the right to enforce the Partnership Guarantee on behalf of
the holders of the Partnership Preferred Securities.
 
AMENDMENTS AND ASSIGNMENT
 
    Except with respect to any changes that do not adversely affect the rights
of holders of Partnership Preferred Securities (in which case no consent will be
required), the Partnership Guarantee may be
 
                                       46
<PAGE>
amended only with the prior approval of the holders of not less than a majority
in liquidation preference of the outstanding Partnership Preferred Securities.
All guarantees and agreements contained in the Partnership Guarantee shall bind
the successors, assigns, receivers, trustees and representatives of the Company
and shall inure to the benefit of the holders of the Partnership Preferred
Securities then outstanding. Except in connection with any permitted merger or
consolidation of the Company with or into another entity or any permitted sale,
transfer or lease of the Company's assets to another entity in which the
surviving corporation (if other than the Company) assumes the Company's
obligations under the Partnership Guarantee, the Company may not assign its
rights or delegate its obligations under the Partnership Guarantee without the
prior approval of the holders of at least a majority of the aggregate stated
liquidation preference of the Partnership Preferred Securities then outstanding.
 
TERMINATION OF THE PARTNERSHIP GUARANTEE
 
    The Partnership Guarantee will terminate and be of no further force and
effect as to the Partnership Preferred Securities upon (i) full payment of the
redemption price of all Partnership Preferred Securities or (ii) full payment of
the amounts payable in accordance with the Limited Partnership Agreement upon
liquidation of the Partnership. The Partnership Guarantee will continue to be
effective or will be reinstated, as the case may be, if at any time any holder
of Partnership Preferred Securities must in accordance with the Partnership Act
restore payment of any sums paid under the Partnership Preferred Securities or
the Partnership Guarantee. The Partnership Act provides that a limited partner
of a limited partnership who wrongfully receives a distribution may be liable to
the limited partnership for the amount of such distribution.
 
GOVERNING LAW
 
    The Partnership Guarantee will be governed by and construed in accordance
with the internal laws of the State of New York.

                   CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
 
GENERAL
 
    In the opinion of Brown & Wood LLP, tax counsel to the Company, the Trust
and the Partnership ("Tax Counsel"), the following summary accurately describes
the material United States federal income tax consequences that may be relevant
to the purchase, ownership and disposition of Trust Preferred Securities. Unless
otherwise stated, this summary deals only with Trust Preferred Securities held
as capital assets by United States Persons (defined herein) who purchase the
Trust Preferred Securities upon original issuance. As used herein, a "United
States Person" means a person that is a citizen or resident of the United
States, a corporation, partnership or other entity created or organized in or
under the laws of the United States or any political subdivision thereof, or an
estate or trust as defined in section 7701(a)(30) of the Internal Revenue Code
of 1986, as amended (the "Code"). The tax treatment of a holder may vary
depending on its particular situation. This summary does not address all the tax
consequences that may be relevant to holders who may be subject to special tax
treatment, such as banks, real estate investment trusts, regulated investment
companies, insurance companies, dealers in securities or currencies, tax-exempt
investors, or foreign investors. This summary does not include any description
of any alternative minimum tax consequences or the tax laws of any state or
local government or of any foreign government that may be applicable to the
Trust Preferred Securities. This summary is based on the Code, the Treasury
regulations promulgated thereunder and administrative and judicial
interpretations thereof, as of the date hereof, all of which are subject to
change, possibly on a retroactive basis.
 
    The Trust Preferred Securities are not being marketed to persons that are
not United States Persons ("non-United States Persons") and, consequently, the
following discussion does not discuss the tax consequences that might be
relevant to non-United States Persons. Moreover, in order to protect the Trust
and the Partnership from potential adverse consequences, non-United States
Persons will be subject to withholding on distributions on the Trust Preferred
Securities held by such non-United States Persons at a rate of 30%. In
determining a holder's status, the United States entity otherwise required to
withhold taxes may rely on an IRS form W-8, an IRS form W-9, or a holder's
certification of its non-foreign status signed under penalty of perjury.
NON-UNITED STATES PERSONS SHOULD CONSULT THEIR TAX ADVISORS AS TO THE SPECIFIC
UNITED STATES FEDERAL INCOME TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP, AND
DISPOSITION OF TRUST PREFERRED SECURITIES.
 
    Tax Counsel has advised that there is no authority directly on point dealing
with securities such as the Trust Preferred Securities or transactions of the
type described herein and that the opinions of Tax Counsel are not binding on
the Internal Revenue Service ("IRS") or the courts, either of which could take a
contrary position. No rulings have been or will be sought from the IRS.
Accordingly, there can be no assurance that the IRS will not challenge the
opinions expressed herein or that a court would not sustain such a challenge.
Nevertheless, Tax Counsel has advised that it is of the view that, if
challenged, the opinions expressed herein would be sustained by a court with
jurisdiction in a properly presented case.
 
    HOLDERS SHOULD CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE TAX
CONSEQUENCES TO THEM OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF THE TRUST
PREFERRED SECURITIES, INCLUDING THE TAX CONSEQUENCES UNDER STATE, LOCAL,
FOREIGN, AND OTHER TAX LAWS AND THE POSSIBLE EFFECTS OF CHANGES IN UNITED STATES
FEDERAL OR OTHER TAX LAWS. FOR A DISCUSSION OF THE POSSIBLE REDEMPTION OF THE
TRUST PREFERRED SECURITIES OR REDEMPTION OF THE PARTNERSHIP PREFERRED SECURITIES
UPON THE OCCURRENCE OF CERTAIN TAX EVENTS SEE "DESCRIPTION OF THE TRUST
PREFERRED SECURITIES -- TRUST SPECIAL EVENT REDEMPTION OR DISTRIBUTION" AND
"DESCRIPTION OF THE PARTNERSHIP PREFERRED SECURITIES -- PARTNERSHIP SPECIAL
EVENT REDEMPTION" RESPECTIVELY.

CLASSIFICATION OF THE TRUST
 
    Tax Counsel is of the opinion that, under current law, and based on certain
representations, facts and assumptions set forth in such opinion, the Trust will
be classified for United States federal income tax purposes as a grantor trust
and not as an association taxable as a corporation. Accordingly, for United
States federal income tax purposes, each holder of Trust Preferred Securities
will be considered the owner of an undivided interest in the Partnership
Preferred Securities held by the Trust, and each holder will be required to
include in its gross income its distributive share of income attributable to the
Partnership, which generally will be equal to such holder's allocable share of
amounts accrued on the Partnership Preferred Securities. No amount included in
income with respect to the Trust Preferred Securities will be eligible for the
corporate dividends-received deduction.
 
CLASSIFICATION OF THE PARTNERSHIP
 
    Tax Counsel is of the opinion that, under current law, and based on certain
representations, facts and assumptions set forth in such opinion, the
Partnership will be classified for United States federal income tax purposes as
a partnership and not as an association or publicly traded partnership taxable
as a corporation.
 
    Tax Counsel's opinion is based on certain factual assumptions relating to
the organization and operation of the Partnership and is conditioned upon
certain representations made by the General Partner and the Partnership as to
factual matters, such as the organization and the operation of the Partnership
and the type and frequency of investments made by the Partnership.
 
    The General Partner has represented that it intends to operate the
Partnership in a manner such that it will continue to constitute a partnership
for all future taxable periods in which any Partnership Preferred Securities
remain outstanding. In particular, pursuant to the Limited Partnership
Agreement, the General Partner is prohibited from taking any action that would
cause the Partnership to constitute a "publicly traded partnership" taxable as a
corporation under section 7704(a) of the Code. Accordingly, it is expected that
the Partnership will continue to qualify as a partnership, and therefore will
not constitute a publicly traded partnership taxable as a corporation, for all
taxable years in which the Partnership Preferred Securities remain outstanding.
 
CLASSIFICATION OF THE DEBENTURES
 
    The Partnership, the Company, the relevant Investment Affiliates and the
holders of the Trust Securities (by acceptance of a beneficial interest in a
Trust Security) will agree to treat the Debentures as indebtedness of the
relevant issuer for all United States tax purposes. In connection with the
issuance of the Debentures, Tax Counsel will issue its opinion that, under
current law, and based on certain representations, facts and assumptions set
forth in such opinion, the Debentures will be classified as indebtedness of the
relevant issuer for United States federal income tax purposes.
 
INCOME AND DEDUCTIONS
 
    A holder's distributive share of income attributable to the Partnership
generally will be substantially equal to the amount of the cash distributions
that accumulate with respect to the Trust Preferred Securities. Accordingly, if
quarterly distributions on the Trust Preferred Securities are paid currently,
the amount of income recognized by a holder during a taxable year generally will
be substantially equal to the cash distributions received by the holder with
respect to its Trust Preferred Securities.
 
    The nature and timing of the income that is allocated to holders of Trust
Preferred Securities will, however, depend on the United States federal income
tax characterization of the investments held by the
 
                                       49
<PAGE>
Partnership during the period in question. Because the Partnership will be an
accrual basis taxpayer for United States federal income tax purposes, income
will accrue on the Trust Preferred Securities and will be allocated to holders
of Trust Preferred Securities on a daily accrual basis, generally at a rate that
is expected to be equal to (and that will not be greater than) the distribution
rate on the Trust Preferred Securities, regardless of the holders' method of
accounting. Actual cash distributions on the Trust Preferred Securities will
not, however, be separately reported as taxable income to the holders at the
time they are received.
 
    If distributions on the Partnership Preferred Securities are not made
currently, the corresponding distributions on the Trust Preferred Securities
will not be made currently. Because the Partnership is an accrual basis taxpayer
it can be expected that during a period in which interest payments on the
Debentures or distributions on the Partnership Preferred Securities are deferred
(for whatever reason), holders will generally recognize income in advance of
their receipt of any cash distributions with respect to their Trust Preferred
Securities. The amount of income that will be allocated to holders of Trust
Preferred Securities during any such deferral period will equal their pro rata
share of the amount of distributions accruing on the Partnership Preferred
Securities during such deferral period.
 
    The Partnership does not presently intend to make an election under Section
754 of the Code. Accordingly, a subsequent purchaser of Trust Preferred
Securities will not be permitted to adjust the tax basis in his allocable share
of the Partnership's assets so as to reflect any difference between his purchase
price for the Trust Preferred Securities and his share of the Partnership's
underlying tax basis in its assets. As a result, a holder of Trust Preferred
Securities may be required to report a larger or smaller amount of income from
holding the Trust Preferred Securities than would otherwise be appropriate based
upon the holder's purchase price for the Trust Preferred Securities.
 
RECEIPT OF PARTNERSHIP PREFERRED SECURITIES UPON LIQUIDATION OF THE TRUST
 
    Under certain circumstances, as described under the caption "Description of
the Trust Preferred Securities -- Trust Special Event Redemption or
Distribution", Partnership Preferred Securities may be distributed to holders of
Trust Preferred Securities in exchange for their Trust Preferred Securities and
in liquidation of the Trust. Unless the liquidation of the Trust occurs as a
result of the Trust being subject to United States federal income tax with
respect to income accrued or received on the Partnership Preferred Securities,
such a distribution to holders would, for United States federal income tax
purposes, be treated as a nontaxable event to each holder, each holder would
receive an aggregate tax basis in the Partnership Preferred Securities equal to
such holder's aggregate tax basis in its Trust Preferred Securities, and a
holder's holding period in the Partnership Preferred Securities so received in
liquidation of the Trust would include the period during which the Trust
Preferred Securities were held by such holder. If, however, the liquidation of
the Trust were to occur because the Trust is subject to United States federal
income tax with respect to income accrued or received on the Partnership
Preferred Securities, the distribution of Partnership Preferred Securities to
holders by the Trust would likely be a taxable event to each holder, and a
holder would recognize gain or loss as if the holder had exchanged its Trust
Preferred Securities for the Partnership Preferred Securities it received upon
the liquidation of the Trust. Such gain or loss would be equal to the difference
between the holder's aggregate tax basis in its Trust Preferred Securities
surrendered in the exchange and the aggregate fair market value of the
Partnership Preferred Securities received in the exchange.
 
REDEMPTION OF TRUST PREFERRED SECURITIES FOR CASH
 
    Under certain circumstances, as described under the caption "Description of
the Trust Preferred Securities -- Mandatory Redemption", "Description of the
Trust Preferred Securities -- Trust Special
 
                                       50
<PAGE>
Event Redemption or Distribution" and "Description of the Partnership Preferred
Securities -- Partnership Special Event Redemption", the General Partner may
cause the Partnership to redeem the Partnership Preferred Securities for cash,
in which event the Trust shall simultaneously apply the proceeds of such
redemption to redeem the Trust Preferred Securities. Under current law, such a
redemption would constitute, for United States federal income tax purposes, a
taxable disposition, and a holder would recognize gain or loss as if it sold the
holder's proportionate interest in the redeemed Partnership Preferred Securities
for an amount of cash equal to the proceeds received upon redemption. See "--
Disposition of Trust Preferred Securities".
 
DISPOSITION OF TRUST PREFERRED SECURITIES
 
    A holder that sells Trust Preferred Securities will recognize gain or loss
equal to the difference between the amount realized on the sale of the Trust
Preferred Securities and the holder's adjusted tax basis in such Trust Preferred
Securities. Such gain or loss will be a capital gain or loss and will be a long-
term capital gain or loss if the Trust Preferred Securities have been held for
more than one year at the time of the sale. A holder will be required to include
accumulated but unpaid distributions on the Partnership Preferred Securities
through the date of disposition in income as ordinary income, and to add such
amount to the adjusted tax basis of its Trust Preferred Securities.
 
    A holder's tax basis in its Trust Preferred Securities generally will equal
(i) the amount paid by such holder for its Trust Preferred Securities, (ii)
increased by the amount includible in income by such holder with respect to its
Trust Preferred Securities, and (iii) reduced by the amount of cash or other
property distributed to such holder with respect to its Trust Preferred
Securities. A holder who acquires Trust Preferred Securities at different prices
may be required to maintain a single aggregate adjusted tax basis in all of his
Trust Preferred Securities and, upon sale or other disposition of some of such
Trust Preferred Securities, to allocate a PRO RATA portion of such aggregate tax
basis to the Trust Preferred Securities sold (rather than maintaining a separate
tax basis in each Trust Preferred Security for purposes of computing gain or
loss on a sale of that Trust Preferred Security).
 
    On August 5, 1997, the Taxpayer Relief Act of 1997 (the "Tax Act"), was
enacted into law. The Tax Act reduces the maximum rates on long-term capital
gains recognized on capital assets held by individual taxpayers for more than
eighteen months as of the date of disposition and would further reduce the
maximum rates on such gains in the year 2001 and thereafter for certain
individual taxpayers who meet specified conditions. Prospective investors should
consult their own tax advisers concerning these tax law changes.
 
OTHER PARTNERSHIP PROVISIONS
 
    SECTION 708. Under Section 708 of the Code, the Partnership will be deemed
to terminate for United States federal income tax purposes if 50% or more of the
capital and profits interests in the Trust are sold or exchanged within a
12-month period. Pursuant to final Treasury regulations issued on May 9, 1997,
if such a deemed termination were to occur, the Partnership would be considered
to have contributed its assets to a new partnership in return for partnership
interests therein and then to have distributed those new partnership interests
to the partners of the old partnership in liquidation thereof.
 
    SECTION 701. The Department of Treasury has promulgated regulations under
Section 701 of the Code that generally permit it to recast a transaction or
disregard a partnership if a partnership is formed or availed of in connection
with a transaction a principal purpose of which is to reduce substantially the
present value of the partners' aggregate federal tax liability in a manner that
is inconsistent with the intent of the partnership provisions of the Code or to
treat a partnership as an aggregate of its partners as appropriate to carry out
the purpose of any provision of the Code or the Treasury regulations thereunder.
The Partnership has been formed for, and will engage in, activities typical for
partnerships. Although there
 
                                       51
<PAGE>
is no precedent that applies to the transactions contemplated herein, Tax
Counsel believes that the Partnership is not of the type intended to fall within
the scope of these regulations.
 
INFORMATION REPORTING AND BACKUP WITHHOLDING
 
    Income on the Trust Preferred Securities will be reported to holders on an
IRS Form 1099, which form should be mailed to holders of Trust Preferred
Securities by January 31 following each calendar year. Payments made on and
proceeds from the sale of Trust Preferred Securities may be subject to a
"back-up" withholding tax of 31% unless the holder complies with certain
identification requirements. Any withheld amount generally will be allowed as a
credit against the holder's United States federal income tax, provided the
required information is timely filed with the IRS.
 
NEW WITHHOLDING REGULATIONS
 
    On October 6, 1997, the Treasury Department issued new regulations (the "New
Regulations") which make certain modifications to the back-up withholding and
information reporting rules described above. The New Regulations attempt to
unify certification requirements and modify reliance standards. The New
Regulations will generally be effective for payments made after December 31,
1998, subject to certain transition rules. Prospective investors are urged to
consult their own tax advisors regarding the New Regulations.

</TABLE>
 
    The Underwriters propose to offer the Trust Preferred Securities, in part,
directly to the public at the initial public offering price set forth on the
cover page of this Prospectus, and, in part, to certain securities dealers at
such price less a concession of $.50 per Trust Preferred Security; provided,
that such concession for sales of 10,000 or more Trust Preferred Securities to
any single purchaser will be $.30 per Trust Preferred Security. The Underwriters
may allow, and such dealers may re-allow, a concession not in excess of $.48 per
Trust Preferred Security to certain brokers and dealers. After the Trust
Preferred Securities are released for sale to the public, the offering price and
other selling terms may from time to time be varied by the Representatives.
 
    In view of the fact that the proceeds of the sale of the Trust Preferred
Securities will ultimately be used to purchase the investment instruments of the
Company and its subsidiaries, the Purchase Agreement provides that the Company
will pay as compensation (the "Underwriters' Compensation") to the Underwriters,
an amount in immediately available funds of $.7875 per Trust Preferred Security
(or $23,625,000 in the aggregate) for the accounts of the several Underwriters;
provided that, such compensation for sales of 10,000 or more Trust Preferred
Securities to any single purchaser will be $.50 per Trust Preferred Security.
Therefore, to the extent of such sales, the actual amount of Underwriters'
Compensation will be less than the aggregate amount specified in the preceding
sentence.
 
    Application will be made to list the Trust Preferred Securities on the New
York Stock Exchange. Trading of the Trust Preferred Securities on the New York
Stock Exchange is expected to commence within a 30-day period after the initial
delivery of the Trust Preferred Securities. The Representatives have advised the
Trust that they intend to make a market in the Trust Preferred Securities prior
to the commencement of trading on the New York Stock Exchange. The
Representatives will have no obligation to make a market in the Trust Preferred
Securities, however, and may cease market making activities, if commenced, at
any time.
 
    Prior to this offering there has been no public market for the Trust
Preferred Securities. In order to meet one of the requirements for listing the
Trust Preferred Securities on the New York Stock Exchange, the Underwriters will
undertake to sell lots of 100 or more Trust Preferred Securities to a minimum of
400 beneficial holders.
 
    The Trust, the Company, and the Partnership have agreed to indemnify the
Underwriters against, or contribute to payments that the Underwriters may be
required to make in respect of, certain liabilities, including liabilities under
the Securities Act of 1933, as amended.
 
    Because MLPF&S, one of the Underwriters in the offering, is an affiliate of
the Company and a member of the National Association of Securities Dealers, Inc.
("NASD"), the offering of Trust Preferred Securities will be conducted pursuant
to the applicable sections of Rule 2810 of the Conduct Rules of the NASD. The
Underwriters may not confirm sales to any discretionary account without the
prior specific written approval of the customer.
 
    The Underwriters are permitted to engage in certain transactions that
stabilize the price of the Trust Preferred Securities. Such transactions consist
of bids or purchases for the purpose of pegging, fixing or maintaining the price
of the Trust Preferred Securities.
 
                                       54
<PAGE>
    If an Underwriter creates a short position in the Trust Preferred Securities
in connection with the offering, I.E., if it sells more Units of the Trust
Preferred Securities than are set forth on the cover page of this Prospectus,
the Underwriter may reduce that short position by purchasing Units of the Trust
Preferred Securities in the open market.
 
    The Underwriters may also impose a penalty bid on certain Underwriters and
selling group members. This means that if an Underwriter purchases Units of the
Trust Preferred Securities in the open market to reduce the Underwriter's short
position or to stabilize the price of the Trust Preferred Securities, they may
reclaim the amount of the selling concession from the Underwriters and selling
group members who sold those Units as part of the offering.
 
    In general, purchases of a security for the purpose of stabilization or to
reduce a short position could cause the price of the security to be higher than
it might be in the absence of such purchases. The imposition of a penalty bid
might also have an effect on the price of a security to the extent that it were
to discourage resales of the security.
 
    Neither the Company nor any of the Underwriters makes 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 Trust Preferred Securities. In
addition, neither the Company nor any of the Underwriters makes any
representation that the Underwriters will engage in such transactions or that
such transactions, once commenced, will not be discontinued without notice.
 
    MLPF&S may use this Prospectus for offers and sales related to market-making
transactions in the Trust Preferred Securities. MLPF&S may act as principal or
agent in these transactions, and the sales will be made at prices related to
prevailing market prices at the time of sale.

    Certain matters of Delaware law relating to the legality of the Trust
Preferred Securities, the validity of the Trust Agreement, the formation of the
Trust and the Partnership and the legality under state law of the Trust
Preferred Securities and the Partnership Preferred Securities are being passed
upon by Skadden, Arps, Slate, Meagher & Flom (Delaware), special Delaware
counsel to the Trust, the Partnership and the Company. The legality under state
law of the Trust Guarantee, the Partnership Guarantee, the Company Debenture and
the Investment Guarantees with respect to the Affiliate Debentures will be
passed upon on behalf of the Trust, the Partnership and the Company by Brown &
Wood LLP, New York, New York. The validity of the Trust Preferred Securities,
the Partnership Preferred Securities and the Trust Guarantee and the Partnership
Guarantee will be passed upon on behalf of the Underwriters by Skadden, Arps,
Slate, Meagher & Flom LLP, New York, New York, counsel to the Underwriters.

    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
reference in this Prospectus, have been audited by Deloitte & Touche LLP,
independent auditors, as stated in their reports incorporated by reference
herein. The Selected Financial Data under the captions "Operating Results",
"Financial Position" and "Common Share Data" for each of the five years in the
period ended December 27, 1996 included in the 1996 Annual Report to
Stockholders of the Company and incorporated by reference herein, has been
derived from consolidated financial statements audited by Deloitte & Touche LLP,
as set forth in their reports included as an exhibit to the Registration
Statement or incorporated by reference herein. Such consolidated financial
statements and related financial statement schedules, and such Selected
Financial Data incorporated by reference in this Prospectus and the Registration
Statement of which this Prospectus is a part, have been included or incorporated
herein by reference in reliance upon such reports of Deloitte & Touche LLP given
upon their authority as experts in accounting and auditing. The balance sheets
of Merrill Lynch Preferred Funding III, L.P. and Merrill Lynch Preferred Capital
Trust III included in this Prospectus have also been audited by Deloitte &
Touche LLP and have been included in reliance upon such reports of Deloitte &
Touche LLP given upon their authority as experts in accounting and auditing.
 
    With respect to unaudited interim financial information for the periods
included in the Quarterly Reports on Form 10-Q which are incorporated herein by
reference, Deloitte & Touche LLP have applied limited procedures in accordance
with professional standards for a review of such information. However, as stated
in their report included in such Quarterly Report on Form 10-Q and incorporated
by reference herein, they did not audit and they do not express an opinion on
such interim financial information. Accordingly, the degree of reliance on their
reports on such information should be restricted in light of the limited nature
of the review procedures applied. Deloitte & Touche LLP are not subject to the
liability provisions of Section 11 of the Act for any such report on unaudited
interim financial information because any such report is not a "report" or a
"part" of the registration statement prepared or certified by an accountant
within the meaning of Sections 7 and 11 of the Act.

To the General Partner and Initial Limited Partner of
  Merrill Lynch Preferred Funding III, L.P.
 
    We have audited the accompanying balance sheet of Merrill Lynch Preferred
Funding III, L.P. (the "Partnership") as of December 19, 1997. This balance
sheet is the responsibility of the Partnership's management. Our responsibility
is to express an opinion on this balance sheet based on our audit.
 
    We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the balance sheet is free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the balance sheet. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall balance sheet presentation. We
believe that our audit of the balance sheet provides a reasonable basis for our
opinion.
 
    In our opinion, the balance sheet referred to above presents fairly, in all
material respects, the financial position of the Partnership as of December 19,
1997, in conformity with generally accepted accounting principles.
