      Each Debt Unit, Series 199_-[ ] offered hereby (collectively, the "Debt

respective Debt Unit class. It is a condition to the issuance of the Debt Units
that the Debt Units have ratings assigned by Moody's Investors Service, Inc.
("Moody's") and by Standard & Poor's Ratings Services, a division of The
McGraw-Hill Companies, Inc. ("S&P"), equivalent to the ratings of the Underlying
Securities, which, as of the date of this Prospectus Supplement were "[ ]" by

                                        the ratio of the Class _-1 Allocation to
                                        the Class _-2 Allocation. The "Class _-1

                                        per annum) of each of the unpaid

                                        due on the Underlying Securities after
                                        the Final Scheduled Distribution Date

                                        case assuming that the Underlying
                                        Securities were paid when due and were
                                        not redeemed prior to their stated

CERTAIN FEDERAL INCOME
  TAX CONSEQUENCES..................    In the opinion of tax counsel to the
                                        Trust, the Trust will be classified for
                                        U.S. Federal income tax purposes as a
                                        grantor trust and not as an association
                                        (or publicly traded partnership) taxable
                                        as a corporation. The Class _-1 Debt
                                        Units will be treated by the Trust as
                                        newly-issued self-amortizing debt
                                        obligations maturing on the Final
                                        Scheduled Distribution Date, although it
                                        is unclear whether the Debt Units will
                                        receive such treatment under the
                                        Internal Revenue Code of 1986, as
                                        amended (the "Code"). The Class _-2 Debt
                                        Units will be deemed to be issued with
                                        original issue discount. See "Certain
                                        Federal Income Tax Consequences".

LISTING.............................    Application will be made to list the
                                        Class _-1 and Class _-2 Debt Units on

RATINGS.............................    It is a condition to the issuance of the
                                        Debt Units that the Debt Units have
                                        ratings assigned by Moody's Investors
                                        Service, Inc. ("Moody's") and by
                                        Standard & Poor's Ratings Services, a
                                        division of The McGraw Hill Companies,
                                        Inc. ("S&P"), equivalent to the ratings
                                        of the Underlying Securities, which, as
                                        of the date of this Prospectus
                                        Supplement were "[ ]" by Moody's and "[
                                        ]" by S&P.

                                        The rating of the Debt Units by Moody's
                                        addresses the likelihood of the ultimate
                                        payment of principal and interest on the
                                        Debt Units or any Underlying Securities
                                        distributed in respect thereof. The
                                        rating of the Debt Units by S&P
                                        addresses the likelihood of timely
                                        receipt of interest on the Class _-1
                                        Debt Units or any Underlying Securities
                                        distributed in respect of Debt Units.
                                        There is no assurance that any such
                                        rating will continue for any period of
                                        time or that it will not be revised or
                                        withdrawn entirely by the related rating
                                        agency if, in its judgment,
                                        circumstances (including, without
                                        limitation, the rating of the Underlying
                                        Securities) so warrant. A revision or
                                        withdrawal of such rating may have an
                                        adverse effect on the market price of
                                        Debt Units. A security rating is not a
                                        recommendation to buy, sell or hold
                                        securities. The rating on the Debt Units
                                        does not constitute a statement
                                        regarding the occurrence or frequency of
                                        redemption on, the Underlying
                                        Securities, and the corresponding effect
                                        on yield to investors. See "Ratings".

         This Prospectus Supplement does not provide information with respect to
the Underlying Securities Issuer. No investigation of the Underlying Securities
Issuer (including, without limitation, no investigation as to its financial
condition or creditworthiness) or of the Underlying Securities (including,
without limitation, no investigation as to its rating) has been made. A
potential Debt Unitholder should obtain and evaluate the same information
concerning the Underlying Securities Issuer as one would obtain and evaluate if
investing directly in the Underlying Securities or in other securities issued by
the Underlying Securities Issuer. None of the Depositor, the Trustee, the
Underwriter, or any of their affiliates, assumes any responsibility for the
accuracy or completeness of any publicly available information of the Underlying
Securities Issuer filed with the Commission or otherwise made publicly available
or considered by a purchaser of the Debt Units in making its investment decision
in connection therewith.

                                  RISK FACTORS

         Prospective purchasers should consider, among other things, the
following factors (as well as the factors set forth under "Risk Factors" in the
Prospectus) in connection with an investment in the Debt Units.

Limited Liquidity

         There can be no assurance that an active public market for any Series
of Debt Units will develop or, if a public market develops, as to the liquidity
of the trading market for such Debt Units. The Depositor has been advised by
Merrill Lynch & Co. that Merrill Lynch & Co. intends to make a market in the
Debt Units, as permitted by applicable laws and regulations, after the issuance
thereof. Merrill Lynch & Co. is not obligated, however, to make a market in the
Debt Units of any Series or Class within such Series and any such market-making
activity may be discontinued at any time without notice at the sole discretion
of Merrill Lynch & Co. If an active public market for the Debt Units does not
develop or continue, the market prices and liquidity of the Debt Units may be
adversely affected.

Maturity and Yield Considerations

         The yield realized by a holder of a Debt Unit is dependent upon a
number of factors, including the purchase price of the Debt Units, the time of
acquisition, and whether a Tax Event occurs and either (i) the maturity date of
the Underlying Securities has been advanced or (ii) the Underlying Securities
Issuer exercises its right to redeem the Underlying Securities subsequent to the
occurrence of a Tax Event. The Depositor has not formulated an opinion as to the
likelihood of a "Tax Event". If a Tax Event occurs and the Underlying Securities
Issuer exercises its right to redeem Underlying Securities prior to their
maturity, or if the Underlying Securities are paid or sold prior to maturity as
a result of a default, an investor's investment in the Debt Units and the
Underlying Securities will have a shorter average maturity than if such right
were not exercised or if such default had not occurred.

Zero Coupon Nature of the Class _-2 Debt Units

         Because the Class _-2 Debt Units do not receive allocations of either
interest or principal until the Final Scheduled Distribution Date, the changes
in market value of the Class _-2 Debt Units as a result of changes in interest
rates or spreads are expected to be more than for the Underlying Securities.
Although the Class _-2 Debt Units will not receive any cash flow during the term
of the Trust, the Class _-2 Debt Units will be deemed to be issued with original
issue discount. See "Certain Federal Income Tax Consequences" herein.

Limited Assets

         The Trust has no significant assets other than the Underlying
Securities. If the Underlying Securities are insufficient to make payments or
distributions on the Debt Units, no other assets will be available for payment
of the deficiency.

No Management of Underlying Securities

         Except as described herein, the Trust will not dispose of any
Underlying Security, regardless of adverse events, financial or otherwise, which
may affect the value of the Underlying Security or the Underlying Securities
Issuer. If there is a payment default on any Underlying Security or any other
default which may result in acceleration of the Underlying Security, the Trust
will only dispose of or otherwise deal with the defaulted Underlying Security in
the manner provided in the Trust Agreement. If a payment default on or
acceleration of the Underlying Securities occurs, the Trust Agreement provides
that the Trust will sell the Underlying Securities notwithstanding market
conditions at the time, and the Trustee will have no discretion to

                                      S-12

<PAGE>



do otherwise. Such sale may result in greater losses than might occur if the
Trust continued to hold the Underlying Securities.

Credit Risk

         The Debt Units represent interests in obligations of a single obligor.
In particular, the Debt Units will be subject to all the risks associated with a
direct investment in unsecured debt obligations of [Name of Underlying
Securities Issuer].

Unsecured Status of Underlying Securities

         According to the Prospectus relating to the Underlying Securities, the
Underlying Securities are general unsecured obligations of the Underlying
Securities Issuer, which rank on a parity with all other unsecured and
unsubordinated indebtedness of the Underlying Securities Issuer, but which are
effectively subordinated to the Underlying Securities Issuer's existing and
future senior secured indebtedness to the extent of the collateral therefor.

No Investigation of Underlying Securities

         None of the Depositor, the Underwriter or the Trustee will (i) make any
investigation of the business condition, financial or otherwise, of the
Underlying Securities Issuer, or (ii) verify any reports or information filed by
the Underlying Securities Issuer with the Commission. Investors are encouraged
to consider publicly available financial and other information regarding [Name
of Underlying Securities Issuer]. The issuance of the Debt Units should not be
construed as an endorsement by the Depositor, the Underwriter or the Trustee of
the financial condition or business prospects of [Name of Underlying Securities
Issuer].

Ratings of the Debt Units

         At the time of issuance, the Debt Units will have ratings assigned by
Moody's and S&P equivalent to the ratings of the Underlying Securities, which,
as of the date of this Prospectus Supplement were "[ ]" by Moody's and "[ ]" by
S&P.

         Any rating issued with respect to the Debt Units is not a
recommendation to purchase, sell or hold a security inasmuch as such ratings do
not comment on the market price of the Debt Units or their suitability for a
particular investor. There can be no assurance that the ratings will remain for
any given period of time or that the ratings will not be revised or withdrawn
entirely by the related rating agency if, in its judgment, circumstances
(including, without limitation, the rating of the Underlying Securities) so
warrant. A revision or withdrawal of such rating may have an adverse effect on
the market price of the Debt Units.


                                    THE TRUST

         The Trust will be formed pursuant to the Supplement, Series 199_-[ ]
(the "Supplement"), which incorporates the Standard Terms for Trust Agreements
(the "Standard Terms"; together with the Supplement, the "Trust Agreement") by
and between the Depositor and the Trustee. Concurrently with the execution and
delivery of the Supplement, the Depositor will deposit the Underlying Securities
into the Trust. The Trustee, on behalf of the Trust, will accept such Underlying
Securities and will deliver the Debt Units to or upon the order of the
Depositor.

         The Underlying Securities were purchased in the secondary market. The
Underlying Securities were not acquired from the Underlying Securities Issuer as
part of any distribution by or pursuant to any agreement

                                      S-13

<PAGE>



with the Underlying Securities Issuer. The Underlying Securities Issuer is not
participating in this offering and will not receive any of the proceeds of the
sale of the Underlying Securities to the Depositor or the issuance of the Debt
Units.


                    DESCRIPTION OF THE UNDERLYING SECURITIES

General

         The Underlying Securities represent the sole assets of the Trust that
are available to make Distributions in respect of the Debt Units. The aggregate
principal amount of the Underlying Securities is $[ ]. The primary economic
terms of the Underlying Securities are described in "Prospectus Supplement
Summary--The Underlying Securities" herein.

         This Prospectus Supplement sets forth certain relevant terms with
respect to the Underlying Securities, but does not provide detailed information
with respect to the Underlying Securities or the Underlying Securities Issuer.
This Prospectus Supplement relates only to the Debt Units offered hereby and
does not relate to the Underlying Securities. All disclosure contained herein
with respect to the Underlying Securities Issuer and the Underlying Securities
is derived from publicly available documents.

         The Underlying Securities Issuer is not participating in, and will not
receive any proceeds in connection with, the offering of the Debt Units. The
Underlying Securities were purchased in the secondary market and will be
deposited into the Trust. The Underlying Securities were not acquired either
from the Underlying Securities Issuer or pursuant to any distribution by or
agreement with the Underlying Securities Issuer.

         According to [Name of Underlying Securities Issuer]'s publicly
available documents, its principal executive offices are located at [Address]
and its telephone number is (___) ___-____. The Underlying Securities Issuer is
subject to the informational requirements of the Exchange Act, and in accordance
therewith files reports and other information with the Commission. Such reports
and other information may be inspected and copied at the public reference
facilities maintained by the Commission at 450 Fifth Street, N.W., Washington,
D.C. 20549, and at the following Regional Offices of the Commission: New York
Regional Office, Room 1100, 7 World Trade Center, New York, New York 10048 and
Chicago Regional Office, Suite 1400, Northwestern Atrium Center, 500 West
Madison Street, Suite 1400, Chicago, Illinois 60661-2511, and copies of such
material can be obtained from the Public Reference Section of the Commission,

of Underlying Securities Issuer] may also be inspected at the Information Center
of the New York Stock Exchange Inc., 20 Broad Street, New York, New York 10005.]

         Although the Depositor has no reason to believe the information
concerning the Underlying Securities or the Underlying Securities Issuer
contained in the Prospectus related to the Underlying Securities is not
reliable, the Depositor has not participated in the preparation of such
documents, or made any due diligence inquiry with respect to the information
provided therein. There can be no assurance that events affecting the Underlying
Securities or the Underlying Securities Issuer have not occurred or have not yet
been publicly disclosed which would affect the accuracy or completeness of the
publicly available documents described above.

         THE TRUST WILL HAVE NO ASSETS OTHER THAN UNDERLYING SECURITIES FROM
WHICH TO MAKE DISTRIBUTIONS OF AMOUNTS DUE IN RESPECT OF THE DEBT UNITS.
CONSEQUENTLY, THE ABILITY OF DEBT UNITHOLDERS TO RECEIVE DISTRIBUTIONS IN
RESPECT OF THE DEBT UNITS WILL DEPEND ENTIRELY ON THE TRUST'S RECEIPT OF
PAYMENTS ON THE UNDERLYING SECURITIES. PROSPECTIVE PURCHASERS OF THE DEBT UNITS
SHOULD CONSIDER CAREFULLY THE FINANCIAL CONDITION OF THE UNDERLYING

         [The Indenture does not limit the amount of Debt Securities which can
be issued thereunder and additional Debt Securities may be issued thereunder up
to the aggregate principal amount which may be authorized from time to time by,
or pursuant to a resolution of, the Underlying Securities Issuer's Board of
Directors or by supplemental indenture.] Reference is made to the Prospectus
Supplement of the Underlying Securities for the terms of the Underlying
Securities not set forth herein. Principal, premium, if any, and interest will
be payable, and the Underlying Securities will be transferable, in the manner
described in the Prospectus for the Underlying Securities.

         The Underlying Securities constitute unsecured and unsubordinated
indebtedness of the Underlying Securities Issuer, and rank on a parity with the
Underlying Securities Issuer's other indebtedness. [However, since [ ] is a
holding company, the right of [ ] and, hence, the right of creditors of [ ]
(including the holders of the Underlying Securities) to participate in any
distribution of the assets of any subsidiaries of [ ], whether upon liquidation,
reorganization, or otherwise, is subject to prior claims of creditors of the
subsidiary, except to the extent that claims of [ ] itself as a creditor of a
subsidiary may be recognized.]

         Federal income tax consequences applicable to the Underlying Securities
are described in the Prospectus for the Underlying Securities.

         The Indenture limits the Underling Securities Issuer's ability to
engage in certain activities and transactions and requires that the Underlying
Securities Issuer perform certain obligations with respect to the Underlying
Securities. [Describe common restrictive, financial and other covenants on the
Underlying Securities Issuer contained in the Indenture.]

         [The following is a summary of the Underlying Security Events of
Default for the Debt Securities:

<PAGE>



                  (a) failure to make payments of principal (and premium, if
         any) and interest to holders of the Debt Securities in the time periods
         given in the Indenture;

                  (b) material breaches of certain representations, warranties
         or covenants or failure to observe or perform in any material respect
         any covenant or agreement under an Indenture continuing for a specified
         period of time after notice thereof is given to the Underlying
         Securities Issuer by the Underlying Securities Trustee or the holders
         of not less than a specified percentage of the Debt Securities;

                  (c) failure by the Underlying Securities Issuer to make any
         required payment of principal (and premium, if any) or interest with
         respect to certain of the other outstanding debt obligations of the
         Underlying Securities Issuer or the acceleration by or on behalf of the
         holders thereof of such securities; [and]

                  (d) certain events of bankruptcy or insolvency relating to the
         Underlying Securities Issuer and the subsidiaries thereof; and

                  [(e) describe any additional events of default with respect to
         the Underlying Securities].]

Advance of Maturity Date or Optional Redemption in Case of Tax Event

         In general, the Underlying Securities may not be redeemed by the
Underlying Securities Issuer. However, the Underlying Securities Issuer states
in the Prospectus for the Underlying Securities that it intends to deduct
interest paid on the Underlying Securities for Federal income tax purposes, and
the Clinton Administration's budget proposal for Fiscal Year 1997 contained a
series of proposed tax law changes that, among other things, would prohibit an
issuer from deducting interest payments on debt instruments with a maturity of
more than 40 years. [Describe relevant provisions including advancing of
maturity date, tax events and special redemptions, if any, applicable to the
Underlying Securities.]

Concerning the Underlying Trustee

         The Underlying Securities Issuer and certain of its affiliates may
maintain banking relationships in the ordinary course of business with the
Underlying Trustee. In addition, the Underlying Trustee and certain of its
affiliates may serve as trustee, authenticating agent, or paying agent with
respect to certain Debt Securities of the Underlying Securities Issuer and
certain of its affiliates.

Global Underlying Securities

         The Underlying Securities and the other Debt Securities comprising the
same series were issued in the form of one or more fully registered global
securities (each, a "Global Security") that were deposited with, or on behalf
of, DTC as more fully described in the Prospectus for the Underlying Securities.
Unless and until it is exchanged for Debt Securities in definitive registered
form, a Global Security may not be transferred except as a whole by the
Depositary for such Global Security to a nominee of such Depositary or by a
nominee of such Depositary to such Depositary or another nominee of such
Depositary or by such Depositary or any such nominee to a successor of such
Depositary or a nominee of such successor.

         Ownership of beneficial interests in a Global Security will be limited
to persons that have accounts with the Depositary for such Global Security
("Participants") or persons that may hold interests through participants.
Ownership of beneficial interests in such Global Security will be shown on, and
the transfer of that ownership will be effected only through, records maintained
by the Depositary for such Global Security or on the record of participants. The
laws of some states require that certain purchasers of securities take physical
delivery of such

                                      S-16

<PAGE>



securities in definitive form. Such limits and such laws may impair the ability
to transfer beneficial interests in a Global Security.

         So long as the Depositary for a Global Security, or its nominee, is the
registered owner of such Global Security, such Depositary or such nominee, as
the case may be, will be considered the sole owner or holder of the Underlying
Securities represented by such Global Security for all purposes under the
Indenture governing such Underlying Securities. Except as provided below, the
Trust as the owner of beneficial interests in a Global Security will not be
entitled to have Underlying Securities of the series represented by such Global
Security registered in its name, will not receive or be entitled to receive
physical delivery of Underlying Securities of such series in definitive form and
will not be considered the owners or holders thereof under the Indenture
governing such Underlying Securities. Principal, premium, if any, and interest
payments on Underlying Securities registered in the name of a Depositary or its
nominee will be made to the Depositary or its nominee, as the case may be, as
the registered owner of the Global Security representing such Underlying
Securities. Neither the Underlying Securities Issuer, the Underlying Trustee for
such Underlying Securities, any Paying Agent nor the Security Registrar for such
Underlying Securities will have any responsibility or liability for any aspect
of the records relating to or payments made on account of beneficial ownership
interests in the Global Security for such Underlying Securities or for
maintaining, supervising or reviewing any records relating to such beneficial
ownership interests.

         The Underlying Securities Issuer may at any time and in its sole
discretion determine not to have the Underlying Securities represented by a
Global Underlying Security and, in such event, will issue Underlying Securities
in definitive form in exchange for the Global Underlying Security representing
such Underlying Securities.


                          DESCRIPTION OF THE DEBT UNITS

General

         The Debt Units will be denominated and distributions with respect
thereto will be payable in U.S. dollars (the "Specified Currency"). The Class
_-1 Debt Units have an initial aggregate principal amount of $[            ].  
The Class _-2 Debt Units have a principal amount at maturity of $[            ].

         The Class _-1 Debt Units will be entitled to receive, on [ ] __ and [ ]
__ of each year (or if such date is not a Business Day, the next succeeding
Business Day) (each, a "Distribution Date"), commencing [ ] __, 199_ and ending
on the Final Scheduled Distribution Date, the interest, if any, received on the
Underlying Securities, which will represent a return of principal on the Class
_-1 Debt Units in accordance with the amortization schedule set forth below, and
the payment of interest at a rate of [ ]% per annum on the outstanding principal
amount of the Class _-1 Debt Units. The Class _-1 Debt Units will amortize on
each Distribution Date on a level yield basis. The Class _-1 Debt Units
generally will not be entitled to any allocation of any principal payments
received on the Underlying Securities.

         Interest on the Class _-1 Debt Units will be calculated on a 360-day
year of twelve 30-day months and will accrue from and including the prior
Distribution Date (or, in the case of the first Interest Accrual Period, from
and including [ ] __, 199_) to but excluding the current Distribution Date.

         The Class _-2 Debt Units will be issued in an initial principal amount
of $[ ] and will not be entitled to distributions of interest. The Class _-2
Debt Units will accrete principal at the rate of [ ]% per annum, in accordance
with the accretion schedule set forth below, to a principal amount of $[ ] on [
] __, 20__. On [ ] __, 20__ the Class _-2 Debt Units will be entitled to a
distribution of all of the Underlying Securities held by the Trust as of such
date. On or prior to the 60th day preceding [ ] __, 20__, the Trustee shall
request instructions from the registered holders of the Class _-2 Debt Units
regarding the account or accounts to which transfer of the Underlying Securities
should be made, and other information relevant to such transfer.

</TABLE>

         The Debt Units will be delivered in registered form. The Debt Units
will be issued, maintained and transferred on the book-entry records of DTC and
its Participants in minimum principal amounts of $[ ] and integral multiples
thereof. [One Debt Unit of each class may be issued in an amount other than an
integral multiple of the applicable minimum denomination.] Each class of Debt
Units will each initially be represented by one or more global certificates
registered in the name of the nominee of DTC (together with any successor
clearing agency selected by the Depositor, the "Clearing Agency"), except as
provided below. The Depositor has been informed by DTC that DTC's nominee will
be Cede. No holder of any such Debt Unit will be entitled to receive a
certificate representing such person's interest, except as set forth below under
"--Definitive Debt Units". Unless and until Definitive Debt Units are issued
under the limited circumstances described herein, all references to actions by
Debt Unitholders with respect to any such Debt Units shall refer to actions
taken by

                                      S-19

<PAGE>



DTC upon instructions from its Participants. See "--Definitive Debt Units" below
and "Description of Debt Units--Global Securities" in the Prospectus.

         Under the rules, regulations and procedures creating and affecting DTC
and its operations, DTC will take action permitted to be taken by a Debt
Unitholder under the Trust Agreement only at the direction of one or more
Participants to whose DTC account such Debt Units are credited. Additionally,
DTC will take such actions with respect to specified voting rights only at the
direction and on behalf of Participants whose holdings of such certificates
evidence such specified voting rights. DTC may take conflicting actions with
respect to voting rights, to the extent that Participants whose holdings of Debt
Units evidence such voting rights authorize divergent action.

Definitive Debt Units

         Definitive Debt Units will be issued to Debt Unitholders or their
nominees, respectively, rather than to DTC or its nominee, only if (i) the
Depositor advises the Trustee in writing that DTC is no longer willing or able
to discharge properly its responsibilities as Clearing Agency with respect to
the Debt Units and the Depositor is unable to locate a qualified successor or
(ii) the Depositor, at its option, elects to terminate the book-entry system
through DTC.

         Upon the occurrence of any event described in the immediately preceding
paragraph, the Trustee is required to notify all Participants of the
availability through DTC of Definitive Debt Units. Upon surrender by DTC of the
definitive certificates representing the Debt Units and receipt of instructions
for re-registration, the Trustee will reissue such Debt Units as Definitive Debt
Units issued in the respective principal amounts owned by the individual owners
of such Debt Units, and thereafter the Trustee will recognize the holders of
such Definitive Debt Units as Debt Unitholders under the Trust Agreement.

Listing on the New York Stock Exchange

         Application will be made to list the Class _-1 and Class _-2 Debt Units
on the NYSE. There can be no assurance that the Debt Units, once listed, will
continue to be eligible for trading on the NYSE.

Collections and Distributions

         Collections on the Underlying Securities that are received by the
Trustee for a Collection Period pursuant to the collection procedures described
herein and in the Prospectus and deposited from time to time into the Debt Unit
Account will be applied by the Trustee on each applicable Distribution Date to
the following distributions in the following order of priority, solely to the
extent of Available Funds (as defined below) on such Distribution Date:

                  (a) to the Trustee, the Trustee's Fee and reimbursement for
         any Extraordinary Expenses (as defined below) incurred by the Trustee
         in accordance with the Trust Agreement pursuant to instructions of not
         less than 100% of the Debt Unitholders;

                  (b) to the holders of the Class _-1 Debt Units, interest at
         the rate of [ ]% per annum on the principal amount of the Class _-1
         Debt Units and principal distributable on such Class _-1 Debt Units on
         such Distribution Date; and

                  (c) to the holders of the Class _-2 Debt Units, on the Final
         Scheduled Distribution Date only, a distribution of all Underlying
         Securities held by the Trust as of such date.

         "Available Funds" for any Distribution Date means the sum of all
amounts received on or with respect to the Underlying Securities during the
preceding Collection Period. In order to reimburse the Trustee for

                                      S-20

<PAGE>



Extraordinary Expenses, however, not less than 100% of the Debt Unitholders may
elect to sell a portion of the Underlying Securities such that the proceeds of
such sale would be sufficient to reimburse the Trustee for such Extraordinary
Expenses.

         If the Trustee has not received payment on the Underlying Securities on
or prior to a Distribution Date, such distribution will be made upon receipt of
payment on the Underlying Securities. No additional amounts will accrue on the
Debt Units or be owed to Debt Unitholders as a result of any such delay;
provided, however, that any additional interest owed and paid by the Underlying
Securities Issuer as a result of such delay shall be paid to the Class _-1 Debt
Unitholders. In the event of a payment default on the Underlying Securities,
approved Extraordinary Expenses (see "Description of the Trust Agreement--The
Trustee" herein) of the Trustee may be reimbursed to the Trustee out of
Available Funds before any distributions to Debt Unitholders are made.

         All amounts received on or with respect to the Underlying Securities,
which are not distributed to Debt Unitholders on the date of receipt, shall be
invested by the Trustee in Eligible Investments. Income on such investments will
constitute property of the Trust. "Eligible Investments" means, with respect to
the Debt Units, those investments consistent with the Trust's status as a
grantor trust for federal income tax purposes and acceptable to the Rating
Agencies as being consistent with the rating of such Debt Units, as specified in
the Trust Agreement. Generally, Eligible Investments must be limited to
obligations or securities that mature not later than the Business Day prior to
the next succeeding Distribution Date.

         There can be no assurance that collections received from the Underlying
Securities over a specified period will be sufficient to make all required
distributions to the Debt Unitholders. To the extent Available Funds are
insufficient to make any such distributions due to any Class of Debt Unit, any
shortfall will be carried over and will be distributable on the next
Distribution Date on which sufficient funds exist to pay such shortfalls. The
Depositor will pay the Ordinary Expenses of the Trustee.

Exchange of Debt Units

         On each Distribution Date, or the next succeeding Business Day if such
Distribution Date is not a Business Day, the Depositor or any affiliate of the
Depositor may, if it holds Class _-2 Debt Units of a certain principal amount
and Class _-1 Debt Units representing a like percentage of the outstanding
principal amount thereof, notify the Trustee, not less than at least 30 (or such
shorter period acceptable to the Trustee) but not more than 45 days prior to
such Distribution Date, that it intends to tender such Debt Units to the Trustee
on such Distribution Date; provided that such distribution will not be made if
it would cause the Trustee or Depositor to fail to satisfy the applicable
requirements for exemption under Rule 3a-7 under the Investment Company Act of
1940. See "Optional Exchange" in the Prospectus. Upon such tender, the Trustee
will deliver Underlying Securities having a principal amount equal to the
combined principal amounts of the Class _-1 Debt Units and Class _-2 Debt Units
being tendered to such Debt Unitholder.

Default on Underlying Securities

         In the event of the occurrence of a payment default on the Underlying
Securities or an acceleration of the maturity of the Underlying Securities, the
Trustee will sell the Underlying Securities. The proceeds of the Underlying
Securities will be allocated between the Class _-1 Debt Units and the Class _-2
Debt Units in accordance with the Allocation Ratio.

         As used herein, the "Class _-1 Allocation" means the sum of the present
values (discounted at the rate of [ ]% per annum) of each of the unpaid interest
coupons due or to become due on the Underlying Securities on or prior to the
Final Scheduled Distribution Date. The "Class _-2 Allocation" means the sum of
the present values (discounted at the rate of [ ]% per annum) of each of the
unpaid interest coupons due or to become

                                      S-21

<PAGE>



due on the Underlying Securities after the Final Scheduled Distribution Date
plus the sum of the present values (discounted at the rate of [ ]% per annum) of
each of the principal amounts of the Underlying Securities (in each case
assuming that the Underlying Securities were paid when due and were not redeemed
prior to their stated maturity).

[Distributions upon Optional Redemption or Advance of Maturity

         In the event of an optional redemption of the Underlying Securities
upon the occurrence of a Tax Event (see "Description of the Underlying
Securities--Advance of Maturity Date or Optional Redemption in Case of Tax
Event" herein), the proceeds of such redemption will be allocated between the
Class _-1 Debt Units and the Class _-2 Debt Units in accordance with the
Allocation Ratio. In the event of an advance of maturity of the Underlying
Securities upon the occurrence of a Tax Event (see "Description of the
Underlying Securities--Advance of Maturity Date or Optional Redemption in Case
of Tax Event" herein), the Underlying Securities will be sold and the proceeds
from such sale will be allocated between the Class _-1 Debt Units and the Class
_-2 Debt Units in accordance with the Allocation Ratio.]


                                  THE DEPOSITOR

         The Depositor, a Delaware corporation, is an indirect, wholly owned,
limited-purpose subsidiary of Merrill Lynch & Co., Inc. The Depositor has not
guaranteed and is not otherwise obligated with respect to the Debt Units.

         The principal office of the Depositor is located at c/o Merrill Lynch &
Co., World Financial Center, New York, New York 10281 (Telephone: (212)
449-1000). See "The Depositor" in the Prospectus.


                       DESCRIPTION OF THE TRUST AGREEMENT

General

         The Debt Units will be issued pursuant to the Trust Agreement, a form
of which is filed as an exhibit to the Registration Statement. A Current Report
on Form 8-K relating to the Debt Units containing a copy of the Trust Agreement
as executed will be filed by the Depositor with the Commission following the
issuance and sale of the Debt Units. The Trust created under the Trust Agreement
(including the Series 199_-[ ] Supplement) will consist of (i) the Underlying
Securities and (ii) all payments on or collections in respect of the Underlying
Securities due after the Closing Date. Reference is made to the Prospectus for
important information in addition to that set forth herein regarding the Trust,
the terms and conditions of the Trust Agreement and the Debt Units. The
following summaries of certain provisions of the Trust Agreement do not purport
to be complete and are subject to the detailed provisions contained in the form
of Trust Agreement, to which reference is hereby made for a full description of
such provisions, including the definition of certain terms used herein.

         The discussions in the Prospectus under "Description of the Trust
Agreement--Advances in Respect of Delinquencies", "--Certain Matters Regarding
the Administrative Agent and the Depositor" (to the extent the discussion
relates to the Administrative Agent), "--Administrative Agent Termination
Events; Rights upon Administrative Agent Termination Event", and "--Evidence as
to Compliance" are not applicable to the Debt Units.

The Trustee

         United States Trust Company of New York will act as trustee (the
"Trustee") for the Debt Units and the Trust pursuant to the Trust Agreement. The
Trustee's offices are located at 114 West 47th Street, New York, New York 10036
and its telephone number is (212) 852-1623.

         Pursuant to the Trust Agreement, the Trustee shall receive compensation
at the rate set forth in the Trust Agreement (the "Trustee Fee").

         The Trust Agreement provides that the Trustee may not take any action
which, in the Trustee's opinion, would or might cause it to incur Extraordinary
Expenses, unless (i) the Trustee is satisfied that it will have adequate
security or indemnity in respect of such costs, expenses and liabilities, (ii)
the Trustee has been instructed to do so by Debt Unitholders representing not
less than the Required Percentage-Remedies (as defined below) of the aggregate
Voting Rights, and (iii) the Debt Unitholders have agreed that such costs will
be paid by the Trustee (x) from the Trust (in the case of an affirmative vote of
100% of the Debt Unitholders) or (y) out of the Trustee's own funds (in which
case the Trustee can receive reimbursement from the Debt Unitholders voting in
favor of such proposal). Extraordinary Expenses that may be reimbursed to the
Trustee from the Trust may be reimbursed out of Available Funds on any
Distribution Date before any distributions to Debt Unitholders on such
Distribution Date are made.

         "Extraordinary Expenses" are defined in the Trust Agreement as any and
all costs, expenses or liabilities arising out of the establishment, existence
or administration of the Trust, other than (i) Ordinary Expenses and (ii) costs
and expenses payable by a particular Debt Unitholder, the Trustee or the
Depositor pursuant to the Trust Agreement.

         "Ordinary Expenses" are defined in the Trust Agreement and are
generally described as the Trustee's ordinary expenses and overhead in
connection with its services as Trustee, including (i) the costs and expenses of
preparing, sending and receiving all reports, statements, notices, returns,
filings, solicitations of consent or instructions, or other communications
required by the Trust Agreement, (ii) the costs and expenses of holding and
making ordinary collection or payments on the assets of the Trust and of
determining and making payments of interest or principal, (iii) the costs and
expenses of the Trust's or Trustee's counsel, accountants and other experts for
ordinary or routine consultation or advice in connection with the establishment,
administration and termination of the Trust, and (iv) any other costs and
expenses that are or reasonably should have been expected to be incurred in the
ordinary course of administration of the Trust.

Events of Default

         An event of default with respect to the Debt Units under the Trust
Agreement (an "Event of Default") will consist of (i) a default in the payment
of any interest on any Underlying Security after the same becomes due and
payable (subject to any applicable grace period); (ii) a default in the payment
of the principal of or any installment of principal of any Underlying Security
when the same becomes due and payable; and (iii) any other event specified as an
"Event of Default" in the Underlying Securities Indenture.

         The Trust Agreement will provide that, within 10 days after the
occurrence of an Event of Default in respect of the Debt Units, the Trustee will
give notice to the Debt Unitholders, transmitted by mail, of all such uncured or
unwaived Events of Default known to it. However, except in the case of an Event
of Default relating to the payment principal of or interest on any of the
Underlying Securities, the Trustee will be protected in withholding such notice
if in good faith it determines that the withholding of such notice is in the
interest of the Debt Unitholders.

         No Debt Unitholder will have the right to institute any proceeding with
respect to the Trust Agreement, unless (i) such Debt Unitholder previously has
given to the Trustee written notice of a continuing breach,

                                      S-23

<PAGE>



(ii) Debt Unitholders evidencing not less than the Required Percentage-Remedies
of the aggregate Voting Rights have requested in writing that the Trustee
institute such proceeding in its own name as Trustee, (iii) such Debt Unitholder
or Debt Unitholders have offered the Trustee reasonable indemnity, (iv) the
Trustee has for 15 days failed to institute such proceeding and (v) no direction
inconsistent with such written request has been given to the Trustee during such
15-day period by Debt Unitholders evidencing not less than the Required
Percentage-Remedies of the aggregate Voting Rights. "Required
Percentage-Remedies" shall mean 662/3% of the Voting Rights.

Voting Rights

         At all times, 100% of all Voting Rights will be allocated between the
Class _-1 Debt Units and the Class _-2 Debt Units in accordance with the
Allocation Ratio. Within each such class, Voting Rights shall be allocated among
Debt Unitholders in proportion to the then outstanding principal amounts of
their respective Debt Units. The "Required Percentage-Amendment" of Voting
Rights necessary to consent to such modification or amendment shall be 662/3%.
Notwithstanding the foregoing, in addition to the other restrictions on
modification and amendment, the Trustee will not enter into any amendment or
modification of the Trust Agreement which would adversely affect in any material
respect the interests of the holders of a class of Debt Units without the
consent of the holders of 100% of such class of Debt Units; provided, however,
that no such amendment or modification will be permitted which would alter the
status of the Trust as a grantor trust for Federal income tax purposes. See
"Description of the Trust Agreement--Modification and Waiver" in the Prospectus.
Further, no amendment will be permitted that would adversely affect in any
material respect the interests of Debt Unitholders of any class without
confirmation by each Rating Agency that such amendment will not result in a
downgrading or withdrawal of its rating of such Debt Units.

Voting of Underlying Securities, Modification of Indenture

         The Trustee, as holder of the Underlying Securities, has the right to
vote and give consents and waivers in respect of such Underlying Securities as
permitted by DTC and except as otherwise limited by the Trust Agreement. In the
event that the Trustee receives a request from DTC, the Underlying Securities
Trustee or the Underlying Securities Issuer for its consent to any amendment,
modification or waiver of the Underlying Securities, the Indenture or any other
document thereunder or relating thereto, or receives any other solicitation for
any action with respect to the Underlying Securities, the Trustee shall mail a
notice of such proposed amendment, modification, waiver or solicitation to each
Debt Unitholder of record as of such date. The Trustee shall request
instructions from the Debt Unitholders as to whether or not to consent to or
vote to accept such amendment, modification, waiver or solicitation. The Trustee
shall consent or vote, or refrain from consenting or voting, in the same
proportion (based on the relative outstanding principal balances of the Debt
Units) as the Debt Units of the Trust were actually voted or not voted by the
Debt Unitholders thereof as of a date determined by the Trustee prior to the
date on which such consent or vote is required, after weighing the votes of the
Class _-1 Debt Unitholders and the votes of the Class _-2 Debt Unitholders
according to the Allocation Ratio; provided, however, that, notwithstanding
anything to the contrary, the Trustee shall at no time vote or consent to any
matter (i) unless such vote or consent would not (based on an opinion of
counsel) alter the status of the Trust as a grantor trust for Federal income tax
purposes, (ii) which would alter the timing or amount of any payment on the
Underlying Securities, including, without limitation, any demand to accelerate
the Underlying Securities, except in the event of an Underlying Security event
of default or an event which with the passage of time would become an Underlying
Security event of default and with the unanimous consent of all outstanding
Class _-1 and Class _-2 Debt Unitholders, or (iii) which would result in the
exchange or substitution of any of the outstanding Underlying Securities
pursuant to a plan for the refunding or refinancing of such Underlying
Securities except in the event of a default under the Indenture and only with
the consent of Debt Unitholders representing 100% of the outstanding Class _-1
and Class _-2 Debt Units. The Trustee shall have no liability for any failure to
act resulting from Debt Unitholders' late return of, or failure to return,
directions requested by the Trustee from the Debt Unitholders.

                                      S-24

<PAGE>




         In the event that an offer is made by the Underlying Securities Issuer
to issue new obligations in exchange and substitution for any of the Underlying
Securities, pursuant to a plan for the refunding or refinancing of the
outstanding Underlying Securities or any other offer is made for the Underlying
Securities, the Trustee shall notify the Class _-1 and Class _-2 Debt
Unitholders of such offer as promptly as practicable. The Trustee must reject
any such offer unless the Trustee is directed by the affirmative vote of all of
the holders of the Class _-1 and Class _-2 Debt Units to accept such offer and
the Trustee has received the tax opinion described above.

         If an event of default under the Indenture occurs and is continuing and
if directed by all of the outstanding Class _-1 and Class _-2 Debt Unitholders,
the Trustee shall vote the Underlying Securities in favor of directing, or take
such other action as may be appropriate to direct, the Underlying Securities
Trustee to declare the unpaid principal amount of the Underlying Securities and
any accrued and unpaid interest thereon to be due and payable. In connection
with a vote concerning whether to declare the acceleration of the Underlying
Securities, the interests of the Debt Unitholders may differ from each other and
from those of other holders of outstanding Debt Securities issued by the
Underlying Securities Issuer.

Termination of The Trust

         The Trust shall terminate upon the earliest to occur of (i) the payment
in full or sale of the Underlying Securities by the Trust after a payment
default on or an acceleration of the Underlying Securities, (ii) the
distribution in full of all amounts due to the Class _-1 and Class _-2 Debt
Unitholders and (iii) the Final Scheduled Distribution Date. See "Description of
the Trust Agreement--Termination" in the Prospectus.


                     CERTAIN FEDERAL INCOME TAX CONSEQUENCES

General

         The following is a general discussion of certain of the material
Federal income tax consequences of the purchase, ownership and disposition of
the Debt Units by an initial holder of Debt Units.

         This summary is based upon laws, regulations, rulings and decisions
currently in effect, all of which are subject to change, possibly on a
retroactive basis. The discussion does not deal with all Federal tax
consequences applicable to all categories of investors, some of which may be
subject to special rules. In addition, this summary is generally limited to
investors who will hold the Debt Units as "capital assets" (generally, property
held for investment) within the meaning of Section 1221 of the Code, and who do
not hold their Debt Units as part of a "straddle," a "hedge" or a "conversion
transaction". Furthermore, no authority exists concerning the tax treatment of
some aspects of the Debt Units, and there can be no assurance that the Treasury
Department will not issue regulations under Section 1286 of the Code which would
modify the treatment described below. Accordingly, the ultimate Federal income
tax treatment of the Debt Units may differ substantially from that described
below. Investors should consult their own tax advisors to determine the Federal,
state, local and other tax consequences of the purchase, ownership and
disposition of the Debt Units.

Tax Status of Trust

         In the opinion of Shearman & Sterling, special Federal income tax
counsel to the Depositor, the Trust will be classified as a grantor trust and
not as an association (or publicly traded partnership) taxable as a corporation
for Federal income tax purposes. Accordingly, each owner of a Debt Unit (a "Debt
Unitholder") will be subject to Federal income taxation as if it owned directly
the portion of the Underlying Securities allocable to such Debt Units and as if
it paid directly its share of reasonable expenses paid by the Trust.


                                      S-25

<PAGE>



Income of Debt Unitholders

         In General. Under Section 1286 of the Code, the Debt Units represent
ownership of newly-issued debt instruments for Federal income tax purposes. The
Class __-2 Debt Units will be treated as an interest in a newly issued debt
instrument issued with original issue discount ("OID").

         The Trust intends to take the position that the Class __-1 Debt Units
represent interests in a newly issued self-amortizing debt instrument having a
principal amount generally equal to the purchase price of the Class __-1 Debt
Units and maturing on the Final Scheduled Distribution Date. Under this
approach, payments made on the Class __-1 Debt Units on each Distribution Date
will partially represent a return of principal and partially represent interest,
as calculated based upon the Debt Unit's yield to maturity. Debt Unitholders
that report income under the cash method of accounting would include in income
upon receipt that portion of the payment representing interest. The Internal
Revenue Service could take the position, however, that the Class __-1 Debt Units
represent a newly issued debt issued with OID.

         In the case of a Debt Unit that represents ownership of a debt
instrument issued with OID, the amount of the OID is equal to the excess of: (i)
the stated redemption price (generally all payments made with respect to the
Underlying Securities on that Debt Unit); over (ii) the purchase price of the
Debt Unit (less accrued interest). The holder of such a Debt Unit, whether using
the cash or accrual method of accounting, generally will be required to include
OID in income in advance of the receipt of some or all of the related cash
payments. The amount of OID allocable to any accrual period is an amount equal
to the product of the instrument's adjusted issued price at the beginning of the
accrual period and its yield to maturity (determined on the basis of compounding
at the close of each accrual period). The adjusted issue price at the beginning
of any accrual period is equal to the purchase price, increased by the accrual
OID for each prior accrual period and reduced by the amount of any cash
payments.

         Modification or Exchange of Underlying Securities. Depending upon the
circumstances, it is possible that a modification of the terms of the Underlying
Securities, including advancing their maturity date following a Tax Event, or a
substitution of other assets for the Underlying Securities following a default
on the Underlying Securities or following a Tax Event, would be a taxable event
to Debt Unitholders on which they would recognize gain or loss.

Deductibility of Trust's Fees and Expenses

         In computing its Federal income tax liability, a Debt Unitholder will
be entitled to deduct, consistent with its method of accounting, its share of
reasonable administrative fees, trustee fees and other fees paid or incurred by
the Trust as provided in Section 162 or 212 of the Code and any allowable
amortization deductions with respect to certain other assets of the Trust. If a
Debt Unitholder is an individual, estate or trust, the deduction for his share
of fees will be a miscellaneous itemized deduction that may be disallowed in
whole or in part.

Purchase and Sale of a Debt Unit

         A Debt Unitholder's tax basis in a Debt Unit generally will equal the
cost of such Debt Unit (A) increased by any amounts of OID and (B) reduced by
any payments of principal, in the case of a Debt Unit representing ownership of
a debt instrument issued without OID, or reduced by any payments included in the
stated redemption price, in the case of a Debt Unit representing ownership of a
debt instrument issued with OID.


                                      S-26

<PAGE>



         If a Debt Unit or Underlying Security is sold, gain or loss will be
recognized equal to the difference between the proceeds of sale allocable to the
Debt Unitholder and the Debt Unitholder's adjusted basis in its Debt Unit. Any
gain or loss will be a capital gain or loss if the Debt Unit was held as a
capital asset.

Distributions on Class _-2 Debt Units

         The distribution of the Underlying Securities to the Class _-2 Debt
Unitholders on the Final Scheduled Distribution Date should not constitute a
taxable transaction to the recipients. Similarly, a redemption by the Trust of
Debt Units in exchange for the Underlying Securities upon the tender by a Debt
Unitholder of Class _-2 Debt Units of a certain principal amount and Class _-1
Debt Units representing a like percentage of the outstanding principal amount
thereof should not constitute a taxable transaction to the Debt Unitholder.

Backup Withholding

         Payments made on the Debt Units and proceeds from the sale of the Debt
Units will not be subject to a "backup" withholding tax of 31% unless, in
general, the Debt Unitholder fails to comply with certain reporting procedures
and is not an exempt recipient under applicable provisions of the Code.

Foreign Debt Unitholders

         To the extent that amounts paid to Debt Unitholders that are not United
States persons ("Foreign Debt Unitholders") are treated as interest with respect
to Underlying Securities originated after July 18, 1984, such amounts generally
will not be subject to the annual 30% withholding tax, provided that such
Foreign Debt Unitholder fulfills certain certification requirements. Under such
requirements, the holder must certify, under penalties of perjury, that it is
not a "United States person" and provide its name and address. The foregoing
discussion of the tax treatment of Foreign Debt Unitholders applies if the Trust
is classified as a grantor trust. If the Trust were not classified as a grantor
trust, the Trust would be treated as a partnership for Federal income tax
purposes. Foreign Debt Unitholders should consult their tax advisors regarding
the withholding tax risks associated with the classification of the Trust as a
partnership.

         A "United States person" means a citizen or resident of the U.S., a
corporation, partnership or other entity created or organized in or under the
laws of the U.S. or any political subdivision thereof, or an estate or trust the
income of which is includable in gross income for U.S. Federal income tax
purposes, regardless of its source.


                              ERISA CONSIDERATIONS

         The Employee Retirement Income Security Act of 1974, as amended
("ERISA"), and the Code impose certain requirements on (a) an employee benefit
plan (as defined in Section 3(3) of ERISA), (b) a plan described in Section
4975(e)(1) of the Code or (c) any entity whose underlying assets include plan
assets by reason of any such plan's investment in the entity (each, a "Plan").

         In accordance with ERISA's general fiduciary standards, before
investing in a Debt Unit, a Plan fiduciary should determine whether such an
investment is permitted under the governing Plan instruments and appropriate for
the Plan in view of its overall investment policy and the composition and
diversification of its portfolio. Other provisions of ERISA and the Code
prohibit certain transactions involving the assets of a Plan and persons who
have certain specified relationships to the Plan ("parties in interest" within
the meaning of ERISA or "disqualified persons" within the meaning of the Code).
Thus, a Plan fiduciary considering an investment in Debt Units should also
consider whether such an investment might constitute or give rise to a
non-exempt prohibited transaction under ERISA or the Code.

                                      S-27

<PAGE>




         Under a "look-through rule" set forth in Section 2510.3-101 of the
United States Department of Labor regulations (the "Regulation"), a Plan's
assets may include an interest in the underlying assets of an entity (such as a
trust) for certain purposes under ERISA if the Plan acquires an equity interest
in such entity. Thus, unless an exception to the look-through rule applies, an
investment in Debt Units by a Plan might result in the assets of the Trust being
deemed to constitute Plan assets, which in turn might mean that certain aspects
of such investment, including the operation of the Trust, might be subject to
the prohibited transaction provisions under ERISA and the Code.

         If the assets of the Trust were deemed to be Plan assets, transactions
involving the Depositor, Underwriter, Trustee, Underlying Securities Trustee and
[Name of Underlying Securities Issuer] might constitute prohibited transactions
with respect to a Plan holding a Debt Unit unless (i) one or more prohibited
transaction exemptions ("PTEs") applies or (ii) in the case of [Name of
Underlying Securities Issuer], it is not a disqualified person or party in
interest with respect to such Plan. Plans maintained or contributed to by the
Depositor, Underwriter, Trustee, Underlying Securities Trustee and [Name of
Underlying Securities Issuer], or any of their affiliates, should not acquire or
hold any Debt Unit.

         If the Trust is deemed to hold Plan assets, the Underlying Securities
would appear to be an indirect loan between the Underlying Securities Issuer and
any Plan owning Debt Units; however, such loan, by itself, would not constitute
a prohibited transaction unless the Underlying Securities Issuer is a party in
interest or disqualified person with respect to such Plan.

         The Underwriter is a broker-dealer registered under the Exchange Act,
and customarily purchases and sells securities for its own account in the
ordinary course of its business as a broker-dealer. Accordingly, the sale of
Debt Units by the Underwriter to Plans may be exempt under PTE 75-1 if the
following conditions are satisfied: (i) the Underwriter is not a fiduciary with
respect to the Plan and is a party in interest or disqualified person solely by
reason of Section 3(14)(B) of ERISA or Section 4975(e)(2)(B) of the Code or a
relationship to a person described in such Sections, (ii) the transaction is at
least as favorable to the Plan as an arm's-length transaction with an unrelated
party and is not a prohibited transaction within the meaning of Section 503(b)
of the Code, and (iii) the Plan maintains for at least six years such records as
are necessary to determine whether the conditions of PTE 75-1 have been met.

         The custodial and other services rendered by the Trustee, and
Underlying Securities Trustee might be exempt pursuant to Section 408(b)(2) of
ERISA and Section 4975(d)(2) of the Code, which exempt services necessary for
the establishment or operation of a Plan under a reasonable contract or
arrangement and for which no more than reasonable compensation is paid. An
arrangement would not be treated as reasonable unless it can be terminated upon
reasonably short notice under the circumstances without penalty. The Trustee may
be terminated upon 60 days prior notice and the approval of Debt Unitholders
owning more than 662/3% of the aggregate beneficial interest of Debt Units. The
Depositor believes the compensation of the Trustee and is reasonable under the
circumstances. The statutory exemption for services noted above does not provide
exemptive relief from prohibited transactions described in Section 406(b) of
ERISA or Section 4975(c)(1)(E) or (F) of the Code. In that regard, a fiduciary
with respect to a Plan should consider whether a sale of the Underlying
Securities to Merrill Lynch & Co. or its affiliates might constitute a
non-exempt prohibited transaction, notwithstanding the sale procedure to accept
the highest bid submitted and the certification of the highest bid and identity
of bidders to the Trustee. [The Trustee shall, prior to any sale of Underlying
Securities to Merrill Lynch & Co. or any of its affiliates, certify that any
such purchaser submitted the highest of at least three bids and shall identify
the other bidders.]

         Other prohibited transaction exemptions could apply to the acquisition
and holding of Debt Units by Plans, and the operation of the Trust, including,
but not limited to: PTE 84-14 (an exemption for certain transaction determined
by an independent qualified professional asset manager), PTE 91-38 (an exemption
for certain transactions involving bank collective investment funds), PTE 90-1
(an exemption for certain transactions

                                      S-28

<PAGE>



involving insurance company pooled separate accounts) or PTE 95-60 (an exemption
for certain transactions involving insurance company general accounts).

         By acquiring and holding a Debt Unit, a Plan shall be deemed to have
represented and warranted to the Depositor, Trustee, and Underwriter that such
acquisition and holding of a Debt Unit does not involve a non-exempt prohibited
transaction with respect to such Plan, including with respect to the activities
of the Trust.

                                  UNDERWRITING

         Subject to the terms and conditions set forth in the Purchase
Agreement, dated as of May __, 1997 (the "Underwriting Agreement"), the
Depositor has agreed to sell to Merrill Lynch & Co. (the "Underwriter"), and the
Underwriter has agreed to purchase, the Debt Units.

         The Depositor has been advised by the Underwriter that the Underwriter
proposes to offer the Debt Units from time to time in negotiated transactions or
otherwise at varying prices to be determined at the time of sale. The
Underwriter may effect such transactions by selling Debt Units to or through
dealers and such dealers may receive compensation in the form of underwriting
discounts, concessions or commissions from the Underwriter and any purchasers of
Debt Units for whom they may act as agents. The Underwriter and any dealers that
participate with the Underwriter in the distribution of Debt Units may be deemed
to be underwriters, and any profit on the resale of Debt Units by them may be
deemed to be underwriting discounts, or commissions under the Securities Act.
Discounts and concessions to dealers will vary but will not exceed [ ]% of the
face amount of the Debt Units.

         [The Underwriter has from time to time provided investment banking and
other financial services to the Underlying Securities Issuer and expects in the
future to provide such services, for which it has received and will receive
customary fees and commissions.]

         The Underwriting Agreement provides that the Depositor will indemnify
the Underwriter against certain civil liabilities, including liabilities under
the Securities Act, or will contribute to payments the Underwriter may be
required to make in respect thereof.


                           VALIDITY OF THE DEBT UNITS

         The validity of the Debt Units will be passed upon for the Depositor
and the Underwriter by Shearman & Sterling, New York, New York.


                                     RATINGS

         It is a condition to the issuance of the Debt Units that the Debt Units
have ratings assigned by Moody's Investors Service, Inc. ("Moody's") and by
Standard & Poor's Ratings Services, a division of The McGraw-Hill Companies,
Inc. ("S&P"), equivalent to the ratings of the Underlying Securities, which, as
of the date of this Prospectus Supplement, were "[ ]" by Moody's and "[ ]" by
S&P.

         The rating of the Debt Units by Moody's addresses the likelihood of the
ultimate payment of principal of and interest on the Debt Units or any
Underlying Securities distributed in respect thereof. The rating of the Debt
Units by S&P addresses the likelihood of timely receipt of interest on the Class
_-1 Debt Units or any Underlying Securities distributed in respect of the Class
_-2 Debt Units and ultimate receipt of principal on any Underlying Securities
distributed in respect of the Class _-2 Debt Units. The ratings address the
likelihood of the receipt by Debt Unitholders of payments required under the
Trust Agreement, and are based primarily on the credit quality of the Underlying
Securities. The rating on the Debt Units does not, however, constitute a
statement regarding the occurrence or frequency of redemptions or prepayments
on, or extensions of the maturity of, the Underlying Securities, and the
corresponding effect on yield to investors.

         A security rating is not a recommendation to buy, sell or hold
securities and may be subject to revision or withdrawal at any time by the
assigning Rating Agency. Each security rating should be evaluated independently
of similar ratings on different securities.

                                      S-30

<PAGE>




         The Depositor has not requested a rating on the Debt Units by any
rating agency other than the Rating Agencies. However, there can be no assurance
as to whether any other rating agency will rate the Debt Units, or, if it does,
what rating would be assigned by any such other rating agency. A rating on the
Debt Units by another rating agency, if assigned at all, may be lower than the
ratings assigned to the Debt Units by the Rating Agencies.

                                    DEPOSITOR

         The Debt Units (the "Debt Units") offered hereby and by supplements
(each, a "Prospectus Supplement") to this Prospectus will be offered from time
to time in one or more series (each, a "Series") and in one or more classes
within each such Series (each, a "Class"), denominated in U.S. dollars or in one
or more other currencies or composite currencies. Debt Units of each respective
Series will be offered in amounts, at prices and on terms to be determined at
the time of sale as described in the Prospectus Supplement accompanying this
Prospectus. Each Series of Debt Units will represent in the aggregate the entire
beneficial ownership interest in a publicly traded debt, or other eligible,
security or a pool of such securities (the "Underlying Securities"), together
with certain other assets, if applicable, described herein or in the applicable
Prospectus Supplement (such assets, together with the Underlying Securities, the
"Deposited Assets"), to be deposited in a trust (the "Trust") for the benefit of
holders of Debt Units of such Series ("Debt Unitholders") by Merrill Lynch
Depositor, Inc., a Delaware corporation that is an indirect, wholly owned,
limited-purpose subsidiary of Merrill Lynch & Co., Inc. (the "Depositor"),
pursuant to a Trust Agreement and a supplement thereto with respect to a Series
(collectively, the "Trust Agreement") between the Depositor, the administrative
agent, if any (the "Administrative Agent"), and the trustee (the "Trustee")
named in the applicable Prospectus Supplement. If so specified in the applicable
Prospectus Supplement, the Trust for a Series of Debt Units may also include, or
the Debt Unitholders of such Debt Units may have the benefit of, any combination
of insurance policies, letters of credit, reserve accounts and other types of
rights or assets designed to support or ensure the servicing and distribution of
amounts due in respect of the Deposited Assets (collectively, "Credit Support").
The Underlying Securities will represent senior or subordinated debt obligations
issued by one or more corporations or other business entities organized under
the laws of the United States of America or any state thereof. As a condition to
the deposit into a Trust of Underlying Securities constituting 10% or more of
the total Underlying Securities with respect to the related Series of Debt
Units, as of the date of the issuance of such Series, the issuer of such
Underlying Securities will be subject to the periodic reporting requirements of
the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and in
accordance therewith will file reports and other information with the Securities
and Exchange Commission (the "Commission"). See "Description of Deposited
Assets--Underlying Securities Issuer". The Underlying Securities will be
purchased in the secondary market; they will not be acquired from the issuer
thereof. No such issuer will participate in the offering of the Debt Units, nor
will such issuer receive any of the proceeds from the sale of the Underlying
Securities to the Depositor or from the issuance of the Debt Units. See
"Description of Debt Units". Except as otherwise provided herein and in the
applicable Prospectus Supplement, the Depositor's only obligations with respect
to each Series of Debt Units will be to assign and deliver the Deposited Assets
and certain related documents to the applicable Trustee and, in certain cases,
to arrange for Credit Support, if any. The principal obligations of an
Administrative Agent, if any is named in the applicable Prospectus Supplement
with respect to a Series of Debt Units, will be pursuant to its contractual
administrative obligations and, only as and to the extent provided in the
applicable Prospectus Supplement, its obligation to make certain cash advances
in the event of payment delinquencies on the Deposited Assets. See "Description
of the Trust Agreement--Advances in Respect of Delinquencies". The Debt Units of
each Series will not represent an obligation of or interest in the Depositor or
Merrill Lynch & Co., Merrill Lynch, Pierce, Fenner & Smith Incorporated
("Merrill Lynch & Co.") or any of their affiliates. Neither the Debt Units nor
the Deposited Assets (unless otherwise specified in such Prospectus Supplement)
will be guaranteed or insured by any governmental agency or instrumentality, or
by the Depositor or Merrill Lynch & Co. or their affiliates.

         Unless otherwise provided in the applicable Prospectus Supplement,
application will be made to list each Series of Debt Units on the New York Stock
Exchange. At the time of issue, each Series of Debt Units offered hereby will be
rated in one of the investment grade categories recognized by one or more
nationally recognized rating agencies. There can be no assurance that an active
public market for any Series of Debt Units will develop or, if a public market
develops, as to the liquidity of the trading market for such Debt Units.

         Unless otherwise specified in the applicable Prospectus Supplements,
each Series of Debt Units initially will be represented by one or more global
securities registered in the name of Cede & Co. ("Cede"), as nominee of The
Depository Trust Company (the "Depositary" or "DTC"). The interests of
beneficial owners of such Debt Units will be represented by book entries on the
records of participating members of DTC. Definitive certificates in registered
form without coupons will be available only under the limited circumstances
described herein under the heading "Description of the Debt Units--Global
Securities".

       PROSPECTIVE INVESTORS SHOULD CONSIDER THE FACTORS SET FORTH HEREIN
                   UNDER "RISK FACTORS", BEGINNING ON PAGE 4.

                                  RISK FACTORS

         In connection with an investment in the Debt Units of any Series,
prospective purchasers should consider, among other things, (1) the risk factors
set forth below and (2) any additional risk factors set forth in the applicable
Prospectus Supplement.

Limited Liquidity

         There can be no assurance that an active public market for any Series
(or Class within such Series) of Debt Units will develop or, if a public market
develops, as to the liquidity of the trading market for such Debt Units. The
Depositor has been advised by Merrill Lynch & Co. that Merrill Lynch & Co.
intends to make a market in the Debt Units, as permitted by applicable laws and
regulations, after the issuance thereof. Merrill Lynch & Co. is not obligated,
however, to make a market in the Debt Units of any Series or Class within such
Series and any such market-making activity may be discontinued at any time
without notice at the sole discretion of Merrill Lynch & Co. If an active public
market for the Debt Units does not develop or continue, the market prices and
liquidity of the Debt Units may be adversely affected.

Recourse Limited

         The Debt Units will not represent a recourse obligation of or interest
in the Depositor, any Administrative Agent, Merrill Lynch & Co., the Underlying
Securities Issuer or any of their affiliates. Unless otherwise specified in the
applicable Prospectus Supplement, the Debt Units of each Series will not be
insured or guaranteed by any government agency or instrumentality, the
Depositor, Merrill Lynch & Co., any person or entity affiliated with the
Depositor or Merrill Lynch & Co., or any other person or entity. The
obligations, if any, of the Depositor with respect to the Debt Units of any
Series will only be pursuant to certain limited representations and warranties
with respect to an Underlying Security or other Deposited Assets, and recourse
with respect to the satisfaction of any such obligations will be limited to any
recourse for a breach of a corresponding representation or warranty that the
Depositor may have against the seller of such Underlying Security or other
Deposited Assets to the Depositor. The Depositor does not have, and is not
expected in the future to have, any assets with which to satisfy any claims
arising from a breach of any representation or warranty.

Limited Assets; Credit Support

         The only material assets expected to be in a Trust are Underlying
Securities and any other Deposited Assets corresponding to the related Series
(or Class within such Series) of Debt Units being offered. The Debt Units do not
represent obligations of the Depositor, any Administrative Agent, Merrill Lynch
& Co. or any of their affiliates and, unless otherwise specified in the
applicable Prospectus Supplement, are not insured or guaranteed by the
Depositor, any Administrative Agent, Merrill Lynch & Co., any of their
affiliates or any other person or entity. Accordingly, Debt Unitholders' receipt
of distributions in respect of the Debt Units will depend entirely on the
performance of and the Trust's receipt of payments with respect to the Deposited
Assets. See "Description of Deposited Assets--Credit Support".

Early Redemption; Reduction in Yield

         The timing of distributions on any Series (or Class within such Series)
of Debt Units is affected by a number of factors. In particular, the type and
maturities of the Underlying Securities and the terms, if any, upon which the
Underlying Securities may be subject to early redemption, purchase or repayment
will generally affect the weighted average life of the related Series of Debt
Units. The effective yield to holders of the Debt Units of any Series may also
be affected by certain aspects of the Deposited Assets. With respect to any
Series of Debt Units the Underlying Securities of which consist of one or more
redeemable securities, the yield to maturity of such Series may be affected by
any optional or mandatory redemption or repayment of the related Underlying
Securities prior to the stated maturity thereof. A variety of tax, accounting,
economic and other factors will influence whether an issuer exercises any right
of redemption in respect of its securities. The applicable Prospectus Supplement
will discuss any calls, puts or other redemption options, and certain other
terms applicable to such Underlying Securities and any other Deposited Assets.

                                        4

         If an Underlying Securities Issuer becomes subject to a bankruptcy or
similar insolvency proceeding, the timing and amount of payments with respect to
the principal of, premium on, if any, and any interest to be distributed in
respect of such Debt Units may be materially and adversely affected. A variety
of factors influence the performance of issuers that are corporations or other
business entities and correspondingly may affect an Underlying Securities
Issuer's ability to satisfy its obligations with respect to the Underlying
Securities, including the Underlying Securities Issuer's operating and financial
condition, its capital structure and other economic, geographic, legal and
social factors.

         The extent to which the yield to maturity of such Debt Units may vary
from the anticipated yield due to the rate and timing of payments on the
Deposited Assets will also depend upon the degree to which they are purchased at
a discount or premium and the degree to which the timing of payments thereon is
sensitive to the rate and timing of payments on the Deposited Assets.

         The yield to maturity of any Series of Debt Units will also be affected
by variations in the interest rates applicable to, and the corresponding
payments in respect of, such Debt Units, to the extent that the Debt Unit Rate
for such Series is based on variable or adjustable interest rates. With respect
to any Series of Debt Units representing an interest in a pool of securities,
disproportionate principal payments (whether resulting from differences in
amortization schedules, payments due on scheduled maturity or upon early
redemption) on the related Underlying Securities having interest rates higher or
lower than the then applicable Debt Unit Rate applicable to such Debt Units may
adversely affect the yield thereon.

         The applicable Prospectus Supplement for a Series of Debt Units will
set forth additional information regarding yield and maturity considerations
applicable to such Series and the related Deposited Assets, including the
related Underlying Securities.

Need to Obtain Information Concerning Underlying Securities Issuers

         A prospective purchaser of Debt Units should obtain and evaluate the
same information concerning each Underlying Securities Issuer as it would obtain
and evaluate if it were investing directly in the Underlying Securities or in
other securities issued by the Underlying Securities Issuer. None of the
Depositor, the Trustee, Merrill Lynch & Co. or any of their affiliates assumes
any responsibility for the accuracy or completeness of any information
concerning any Underlying Securities Issuer (including, without limitation, no
investigation as to its financial condition or creditworthiness) or concerning
the Underlying Securities (whether or not such information is filed with the
Commission) or otherwise considered by a purchaser of the Debt Units in making
its investment decision in connection therewith; provided that the foregoing
shall not apply to any information concerning the Underlying Securities and any
Underlying Securities Issuer that is expressly set forth in this Prospectus or
an applicable Prospectus Supplement. The issuance of Debt Units of any Series
should not be construed as an endorsement by the Depositor, Merrill Lynch & Co.
or the Trustee of the financial condition or business prospects of any
Underlying Securities Issuer.

Risk of Loss if Public Information Not Available

         If an obligor on any Concentrated Underlying Securities ceases to file
periodic reports under the Exchange Act, then, if so provided in the applicable
Prospectus Supplement or if so required pursuant to applicable law, the
Depositor will instruct the Trustee of the relevant Trust to sell all of such
Concentrated Underlying Securities and to distribute the proceeds from such sale
to the Debt Unitholders in accordance with the Allocation Ratio (as defined in
the Prospectus Supplement). Otherwise, if so provided in the applicable
Prospectus Supplement, the Depositor will instruct the Trustee of the relevant
Trust to distribute such Concentrated Underlying Securities in accordance with
the Allocation Ratio.

Certain Legal Aspects

         The applicable Prospectus Supplement may set forth certain legal
considerations that are applicable to a specific Series of Debt Units being
offered in connection with that Prospectus Supplement or the Deposited Assets
assigned and delivered to the related Trust.

Ratings of the Debt Units

         At the time of issuance, the Debt Units of a Series (or each Class of
such Series) will be rated in one of the investment grade categories by one or
more nationally recognized rating agencies (a "Rating Agency"). Unless otherwise
specified in the applicable Prospectus Supplement, the rating of any Series or
Class of Debt Units is based primarily on the related Deposited Assets and any
Credit Support and the relative priorities of the Debt Unitholders of such
Series or Class to receive collections from, and to assert claims against, the
Trust with respect to such Deposited Assets and any Credit Support.

         Any rating issued with respect to the Debt Units is not a
recommendation to purchase, sell or hold a security; such ratings do not comment
on the market price of the Debt Units or their suitability for a particular
investor. There can be no assurance that the ratings will remain for any given
period of time or that any rating will not be revised or withdrawn entirely by
the related rating agency if, in its judgment, circumstances (including, without
limitation, the rating of the Underlying Securities) so warrant. A revision or
withdrawal of such rating may have an adverse effect on the market price of the
Debt Units.

Global Securities

         Unless otherwise specified in the applicable Prospectus Supplement, the
Debt Units of each Series will initially be represented by one or more Global
Securities deposited with, or on behalf of, a Depositary (as defined below) and
will not be issued as individual definitive Debt Units to the purchasers of such
Debt Units. Consequently, unless and until such individual definitive Debt Units
of a particular Series are issued, such purchasers will not be recognized as
Debt Unitholders under the Trust Agreement. Until such time, such purchasers
will only be able to exercise the rights of Debt Unitholders indirectly through
the Depositary and its respective participants and, as a result, the ability of
any such purchaser to pledge that Debt Unit to persons or entities that do not
participate in the Depositary's system, or otherwise to act with respect to such
Debt Unit, may be limited. See "Description of Debt Units--Global Securities"
and any further description contained in the applicable Prospectus Supplement.

Limitation on Remedies Due to Passive Nature of the Trust

         The Trustee with respect to any Series of Debt Units will hold the
Deposited Assets for the benefit of the Debt Unitholders. Each Trust will
generally hold the related Deposited Assets to maturity and not dispose of them,
regardless of adverse events, financial or otherwise, which may affect any
Underlying Securities Issuer or the value of the Deposited Assets. Except as
indicated below, a holder will not be able to dispose of or take other actions
with respect to any Deposited Assets. Under certain circumstances described in
the applicable Prospectus Supplement, the Trustee will (or will at the direction
of a specified percentage of Debt Unitholders of the relevant Series) dispose
of, or take certain other actions in respect of, the Deposited Assets. In
certain limited circumstances, such as a mandatory redemption of Underlying
Securities or the exercise by a third party of the right to purchase Underlying
Securities (and as described below under "Description of Deposited
Assets--Principal Terms of Underlying Securities"), the Trustee may dispose of
the Deposited Assets prior to maturity. The applicable Prospectus Supplement
will describe the particular circumstances, if any, under which a Deposited
Asset may be disposed of prior to maturity.

Amendment of Trust Agreement

         The Trust Agreement may be amended or otherwise modified with the
consent of a percentage of Debt Unitholders specified in the Prospectus
Supplement (which percentage will not be less than a majority). Any such
amendment or other modification could have a material adverse effect on those
Debt Unitholders of the relevant

                                        6

<PAGE>



Series that do not consent to such amendment or other modification. However, the
Trust Agreement provides that any amendment or other modification that would
reduce the amount of, or defer the date of, distributions to Debt Unitholders of
a Series (or Class within such Series) may become effective only with the
consent of each affected Debt Unitholder of that Series (or Class within such
Series) and that, if so specified in the applicable Prospectus Supplement, any
such amendment or other modification that would result in the reduction or
withdrawal of the then current rating assigned to the Debt Units of a Series (or
Class within such Series) by a Rating Agency would require the consent of a
specified higher percentage of Debt Unitholders of that Series (or Class within
such Series).
                                   ----------

         The Prospectus Supplement for each Series of Debt Units will set forth
information regarding additional risk factors, if any, applicable to such Series
(and each Class within such Series).


                                  THE DEPOSITOR

         The Depositor, a Delaware corporation, is an indirect, wholly owned,
limited-purpose subsidiary of Merrill Lynch & Co., Inc. The principal office of
the Depositor is c/o Merrill Lynch & Co., Inc., World Financial Center, New
York, New York 10281.

         The Certificate of Incorporation of the Depositor provides that the
Depositor may conduct any lawful activities necessary or incidental to serving
as depositor of one or more trusts that may issue and sell Debt Units. The
Certificate of Incorporation of the Depositor provides that any securities,
except for subordinated securities, issued by the Depositor must be rated in one
of the four highest categories available by any Rating Agency rating the Series.
Formation of a grantor trust will not relieve the Depositor of its obligation to
issue only securities, except for subordinated securities, rated in one of the
four highest rating categories. Pursuant to the terms of the Trust Agreement,
the Depositor may not issue any securities which would result in the lowering of
the then current ratings of the outstanding Debt Units of any Series.


                                 USE OF PROCEEDS

         The net proceeds to be received from the sale of each Series of, if the
related Deposited Assets are purchased by the Depositor, Debt Units (whether or
not offered hereby) will be used by the Depositor to purchase the related
Deposited Assets, if the related Deposited Assets are purchased by the
Depositor, and arrange certain Credit Support, if any, including, if specified
in the applicable Prospectus Supplement, making required deposits into any
reserve account or the applicable Debt Unit Account (as defined below) for the
benefit of the Debt Unit holders of such Series or Class. The remaining net
proceeds, if any, will be used by the Depositor for purposes related to the
deposit of Deposited Assets into one or more Trusts and the preparation,
distribution and filing by the Depositor of periodic reports and other
information, including, but not limited to, the fees and expenses of the
Depositor incurred in connection with the ongoing activities of the Trust(s).


                             FORMATION OF THE TRUST

         The Depositor will assign and deliver the Deposited Assets for each
Series of Debt Units to the Trustee named in the applicable Prospectus
Supplement, in its capacity as Trustee, for the benefit of the Debt Unitholders
of such Series. See "Description of the Trust Agreement--Assignment of Deposited
Assets". The Trustee named in the applicable Prospectus Supplement will
administer the Deposited Assets pursuant to the Trust Agreement and will receive
a fee for such services (the "Trustee's Fee"). Any Administrative Agent named in
the applicable Prospectus Supplement will perform such tasks as are specified
therein and in the Trust Agreement and will receive a fee for such services (the
"Administration Fee") as specified in the Prospectus Supplement. See
"Description of the Trust Agreement--Collection and Other Administrative
Procedures" and "--Retained Interest; Administrative Agent Compensation and
Payment of Expenses". Unless otherwise provided in the applicable Prospectus
Supplement, the Trustee or an Administrative Agent, if applicable, will either
cause the assignment of the Deposited

                                        7

<PAGE>



Assets to be recorded on the books and records of The Depository Trust Company
or will obtain an opinion of counsel that no recordation is required to obtain a
first priority perfected security interest in such Deposited Assets.

         Unless otherwise stated in the Prospectus Supplement, the Depositor's
assignment of the Deposited Assets to the Trustee will be without recourse to
the Depositor (except as to certain limited representations and warranties, if
any).

         To the extent provided in the applicable Prospectus Supplement, the
obligations of an Administrative Agent so named therein with respect to the
Deposited Assets will consist primarily of its contractual administrative
obligations, if any, under the Trust Agreement, its obligation, if any, to make
certain cash advances in the event of delinquencies in payments on or with
respect to any Deposited Assets described under "Description of the Trust
Agreement--Advances in Respect of Delinquencies", and its obligations, if any,
to purchase Deposited Assets as to which there has been a breach of certain
representations and warranties or as to which the documentation is materially
defective. The obligations of an Administrative Agent, if any, named in the
applicable Prospectus Supplement to make advances will be limited to amounts
which any such Administrative Agent believes ultimately would be recoverable
under any Credit Support, insurance coverage, the proceeds of liquidation of the
Deposited Assets or from other sources available for such purposes. See
"Description of the Trust Agreement--Advances in Respect of Delinquencies".

         Unless otherwise provided in the applicable Prospectus Supplement, each
Trust will consist of (i) such Deposited Assets, or interests therein, exclusive
of any interest in such assets (the "Retained Interest") retained or acquired by
the Depositor, or any previous owner thereof or any other person or entity, as
from time to time are specified in the Trust Agreement; (ii) such assets as from
time to time are identified as deposited in the related Debt Unit Account; (iii)
rights under the agreement or agreements pursuant to which the Trustee has
acquired such Deposited Assets; (iv) those elements of Credit Support, if any,
provided with respect to any Series (or Class within such Series) within such
Series that are specified as being part of the related Trust in the applicable
Prospectus Supplement, as described therein and under "Description of Deposited
Assets--Credit Support"; and (v) any cash or other property received upon the
sale, exchange, collection or other disposition of any of the foregoing.


                        MATURITY AND YIELD CONSIDERATIONS

         Each Prospectus Supplement will, to the extent applicable, contain
information with respect to the types and maturities of the related Underlying
Securities and the terms, if any, upon which such Underlying Securities may be
subject to early redemption or repayment. The provisions of the Underlying
Securities with respect to the foregoing will, unless otherwise specified in the
applicable Prospectus Supplement, affect the weighted average life of the
related Series of Debt Units.

         The effective yield to holders of the Debt Units of any Series (and
Class within such Series) may be affected by certain aspects of the Deposited
Assets or the manner and priorities of allocations of collections with respect
to such Deposited Assets between the Classes of a given Series. With respect to
any Series of Debt Units the Underlying Securities of which consist of one or
more redeemable securities, the yield to maturity of such Series (or Class
within such Series) may be affected by any optional or mandatory redemption or
repayment of the related Underlying Securities prior to the stated maturity
thereof. A variety of tax, accounting, economic, and other factors will
influence whether a corporate issuer exercises any right of redemption in
respect of its securities. All else remaining equal, if prevailing interest
rates are below the interest rates on the related Underlying Securities, the
likelihood of redemption would be expected to increase. There can be no
certainty as to whether any Underlying Security redeemable at the option of the
Underlying Security Issuer will be repaid prior to its stated maturity.

         Unless otherwise specified in the applicable Prospectus Supplement,
each of the Underlying Securities will be subject to acceleration upon the
occurrence of certain events of default under the terms of the Underlying
Securities. The maturity and yield on the Debt Units will be affected by any
early repayment of the Underlying Securities as a result of the acceleration of
the Underlying Securities by or on behalf of the holders thereof. See
"Description of the Deposited Assets--Underlying Securities Indenture". If an
Underlying Securities Issuer becomes subject to a bankruptcy proceeding, the
timing and amount of payments with respect to the principal of, the premium

                                        8

<PAGE>



on, if any, and the interest to be distributed in respect of the Debt Units may
be materially and adversely affected. A variety of factors influence the
performance of issuers that are corporations or other business entities and
correspondingly may affect an Underlying Securities Issuer's ability to satisfy
its obligations under the Underlying Securities, including the company's
operating and financial condition, leverage, and economic, geographic, legal and
social factors.

         The extent to which the yield to maturity of such Debt Units may vary
from the anticipated yield due to the rate and timing of payments on the
Deposited Assets will depend upon the degree to which they are purchased at a
discount or premium and the degree to which the timing of payments thereon is
sensitive to the rate and timing of payments on the Deposited Assets.

         The yield to maturity of any Series (or Class) of Debt Units will also
be affected by variations in the interest rates applicable to, and the
corresponding payments in respect of, such Debt Units, to the extent that the
Debt Unit Rate, if any, for such Series (or Class) is based on variable or
adjustable interest rates. With respect to any Series of Debt Units representing
an interest in a pool of debt, or other eligible, securities, disproportionate
principal payments (whether resulting from differences in amortization
schedules, payments due on scheduled maturity or upon early redemption) on the
related Underlying Securities having interest rates higher or lower than the
then applicable Debt Unit Rates, if any, applicable to such Debt Units may
affect the yield thereon.

         The Prospectus Supplement for each Series of Debt Units will set forth
additional information regarding yield and maturity considerations applicable to
such Series (and each Class within such Series) and the related Deposited
Assets, including the applicable Underlying Securities.


                          DESCRIPTION OF THE DEBT UNITS

         Each Series (or, if more than one Class exists, the Classes within such
Series) of Debt Units will be issued pursuant to a Trust Agreement and a
supplement thereto between the Depositor and the Trustee named in the applicable
Prospectus Supplement, a form of which Trust Agreement is attached as an exhibit
to the Registration Statement. The provisions of the Trust Agreement (as so
supplemented) may vary depending upon the terms of both the Debt Units to be
issued thereunder and the Deposited Assets, the Credit Support, if any, and
related Trust. The following summaries describe material provisions of the Trust
Agreement which may be applicable to each Series of Debt Units. The applicable
Prospectus Supplement for a Series of Debt Units will describe any material
provision of the Trust Agreement that is not described herein or the description
of which is materially different from the description herein. The following
summaries do not purport to be complete and are subject to the detailed
provisions of the form of Trust Agreement to which reference is hereby made for
a full description of such provisions, including the definition of certain terms
used, and for other information regarding the Debt Units. Wherever particular
defined terms of the Trust Agreement are referred to, such defined terms are
incorporated herein by reference as part of the statement made, and the
statement is qualified in its entirety by such reference. As used herein with
respect to any Series, the term "Debt Unit" refers to all the Debt Units of that
Series (and each Class within such Series), whether or not offered hereby and by
the applicable Prospectus Supplement, unless the context otherwise requires.

         A copy of the applicable series supplement to the Trust Agreement
relating to each Series of Debt Units issued from time to time will be filed by
the Depositor as an exhibit to a Current Report on Form 8-K to be filed with the
Commission following the issuance of such Series.

General

         There is no limit on the amount of Debt Units that may be issued under
the Trust Agreement, and the Trust Agreement will provide that Debt Units of the
applicable Series may be issued in multiple Classes. The Series (or Classes
within such Series) of Debt Units to be issued under the Trust Agreement will
represent the entire beneficial ownership interest in the Trust for such Series
created pursuant to the Trust Agreement and each such Class will be allocated
certain relative priorities to receive specified collections from, and a certain
percentage ownership interest of the assets deposited in, such Trust, all as
identified and described in the applicable Prospectus Supplement. See
"Description of Deposited Assets--Collections". Reference is made to the
applicable Prospectus Supplement for a description of the following terms of the
Series of Debt Units in respect of which this Prospectus and such Prospectus

         represents a significant portion of all such Deposited Assets and any
         related Credit Support, if any, information concerning the material
         terms of each such Underlying Security, the identity of the issuer

         notional amount, as applicable, of each Class thereof;

                  (vi) if applicable, the relative rights and priorities of each
         such Class (including the method for allocating collections from and

         Depositor, Merrill Lynch & Co. or the Trustee, or their respective
         designees, may withdraw a portion of the assets of the Trust (or of the
         proceeds obtained by the Trust upon the sale or other disposition of
         such assets) in exchange for surrendering a pro rata portion of the
         Debt Units (in each case to the extent not inconsistent with continued
         satisfaction of the applicable requirements for exemption under Rule
         3a-7 under the Investment Company Act of 1940, as amended, and all
         applicable rules, regulations and interpretations thereunder and for
         treatment of the Trust as a "grantor trust" for U.S. Federal income tax
         purposes) and the periods within which or the dates on which, and the

         periods within which or the dates on which, and the terms and
         conditions upon which any such option may be exercised, in whole or in
         part;

<PAGE>




                  (x) the rating of each Series or each Class within such Series
         offered hereby;

                  (xi) if other than denominations of $1,000 and any integral
         multiple thereof, the denominations in which such Series or each Class
         within such Series will be issuable;

                  (xii) whether the Debt Units of any Class within a given
         Series are to be entitled to (1) principal distributions, with
         disproportionate, nominal or no interest distributions, or (2) interest
         distributions, with disproportionate, nominal or no principal
         distributions ("Strip Debt Units"), and the applicable terms thereof;

         such Series and the circumstances and conditions, if any, when such
         Specified Currency may be changed, at the election of the Depositor or
         a Debt Unitholder, and the currency or currencies in which any
         principal of or any premium or any interest on such Series or Class are
         to be distributed pursuant to such election;

                  (xv) all applicable Required Percentages and Voting Rights
         (each as defined below) relating to the manner and percentage of votes
         of Debt Unitholders of such Series and each Class within such Series
         required with respect to certain actions by the Depositor or the
         Trustee under the Trust Agreement or with respect to the applicable
         Trust; and

                  (xvi) all other material terms of such Series or Class within
         such Series of Debt Units.

         The United States Federal income tax consequences and ERISA
consequences relating to any Series or any Class within such Series of Debt
Units will be described in the applicable Prospectus Supplement. In addition,
any special considerations, the specific terms and other information with
respect to the issuance of any Series or Class within such Series of Debt Units
on which the principal of and any premium and interest are distributable in a
Specified Currency other than U.S. dollars will be described in the applicable
Prospectus Supplement. Unless otherwise specified in the applicable Prospectus
Supplement, the U.S. dollar equivalent of the public offering price or purchase
price of a Debt Unit having a Specified Currency other than U.S. dollars will be
determined on the basis of the noon buying rate in New York City for cable
transfers in foreign currencies as certified for customs purposes by the Federal
Reserve Bank of New York for such Specified Currency on the applicable issue
date. As specified in the applicable Prospectus Supplement, such determination
will be made by the Depositor, the Trustee, the Administrative Agent, if any, or
an agent thereof as exchange rate agent for each Series of Debt Units.

         Except as otherwise provided in the applicable Prospectus Supplement,
Transfers of beneficial ownership interests in any Global Security will be
effected in accordance with the normal procedures of The Depository Trust
Company or any other specified Depositary. In the event that Definitive Debt
Units are issued in the limited circumstances described herein, they may be
transferred or exchanged for like Debt Units of the same Series at the corporate
trust office or agency of the applicable Trustee in the City and State of New
York, subject to the limitations provided in the Trust Agreement, without the
payment of any service charge, other than any tax or governmental charge payable
in connection therewith.

Distributions

         Distributions allocable to principal, premium (if any) and interest on
the Debt Units of each Series (and each Class within such Series) will be made
by or on behalf of the Trustee on each Distribution Date as specified in the
applicable Prospectus Supplement, and the amount of each distribution will be
determined as of the close of business on the date specified in the applicable
Prospectus Supplement (the "Determination Date").

         Unless otherwise provided in the applicable Prospectus Supplement and
except as provided in the succeeding paragraph, distributions with respect to
Debt Units will be made at the corporate trust office or agency

                                       11

<PAGE>



of the Trustee specified in the applicable Prospectus Supplement in The City of
New York; provided that any such amounts distributable on the Final Scheduled
Distribution Date of a Debt Unit will be distributed only upon surrender of such
Debt Unit at the applicable location set forth above.

         Unless otherwise specified in the applicable Prospectus Supplement,
distributions on Debt Units will be made, except as provided below, by check
mailed to the Debt Unitholders listed on the relevant Record Date in the
ownership register maintained for that purpose under the Trust Agreement (which,
in the case of Global Securities, will be a nominee of the Depositary). A Debt
Unitholder of $10,000,000 or more in aggregate principal amount of Debt Units of
a given Series, and any holder of a Global Security, shall be entitled to
receive such distributions by wire transfer of immediately available funds, but
only if appropriate wire transfer instructions have been received in writing by
the Trustee for such Series not later than 15 calendar days prior to the
applicable Distribution Date.

         Except as otherwise specified in the applicable Prospectus Supplement,
"Business Day" with respect to any Debt Unit means any day other than (i)
Saturday or Sunday or (ii) a day on which banking institutions are authorized or
required by law or regulation to be closed for business or (iii) a day that is
not a business day, as such term is used in the Indenture to the Underlying
Securities.

Interest on the Debt Units

         Each Class of Debt Units (other than certain Classes of Strip Debt
Units) of a given Series may have a different Debt Unit Rate, which may be a
fixed or floating Debt Unit Rate, as described below. In the case of Strip Debt
Units with a nominal or no Debt Unit Principal Balance, such distributions of
interest will be in an amount described in the applicable Prospectus Supplement.
For purposes hereof, "Notional Amount" means the notional principal amount
specified in the applicable Prospectus Supplement on which interest on Strip
Debt Units with a nominal or no Debt Unit Principal Balance will be made on each
Distribution Date. Reference to the Notional Amount of a Class of Strip Debt
Units herein or in a Prospectus Supplement does not indicate that such Debt
Units represent the right to receive any distribution in respect of principal in
such amount, but rather the term "Notional Amount" is used solely as a basis for
calculating the amount of required distributions and determining certain
relative voting rights, all as specified in the applicable Prospectus
Supplement. The interest rate applicable to the Debt Units (the "Debt Unit
Rate") will be described in the applicable Prospectus Supplement and will be
based upon the rate of interest received on the Underlying Securities, Credit
Support, if any, and any payments payable in respect of the Retained Interest
(if any). The Debt Unit Rate may be either a fixed rate or a floating rate.

         Fixed Rate Debt Units. Each Series of Debt Units with a fixed Debt Unit
Rate ("Fixed Rate Debt Units") will bear interest, on the outstanding Debt Unit
Principal Balance, from its Original Issue Date, or from the last date to which
interest has been paid, at the fixed Debt Unit Rate stated on the face thereof
and in the applicable Prospectus Supplement until the principal amount thereof
is distributed or made available for repayment (or, in the case of Fixed Rate
Debt Units with a nominal or no principal amount, until the Notional Amount
thereof is reduced to zero), except that, if so specified in the applicable
Prospectus Supplement, the Debt Unit Rate for such Series or any such Class or
Classes may be subject to adjustment from time to time in response to designated
changes in the rating assigned to such Debt Units by one or more rating
agencies, in accordance with a schedule or otherwise, all as described in such
Prospectus Supplement. Unless otherwise set forth in the applicable Prospectus
Supplement, interest on each Series or Class of Fixed Rate Debt Units will be
distributable in arrears on each Distribution Date specified in such Prospectus
Supplement. Each such distribution of interest shall include interest accrued
through the day specified in the applicable Prospectus Supplement. Unless
otherwise specified in the applicable Prospectus Supplement, interest on Fixed
Rate Debt Units will be computed on the basis of a 360-day year of twelve 30-day
months.

         Floating Rate Debt Units. Each Series of Debt Units with a variable
Debt Unit Rate ("Floating Rate Debt Units") will bear interest, on the
outstanding Debt Unit Principal Balance, from its Original Issue Date to but
excluding the first Interest Reset Date (as defined below) for such Series at
the Initial Debt Unit Rate set forth on the face thereof and in the applicable
Prospectus Supplement. Thereafter, the Debt Unit Rate on such Series for each
Interest Reset Period (as defined below) will be determined by reference to an
interest rate basis (the "Base Rate"), plus or minus the Spread, if any, or
multiplied by the Spread Multiplier, if any. The Base Rate for any Series of
Debt Units will, as described in greater detail below, be a fluctuating rate of
interest that is publicly

                                       12

<PAGE>



available and is established by reference to quotations provided by third
parties of the interest rate from time to time prevailing on loans or other
extensions of credit in a specified credit market. The "Spread" is the number of
basis points (one basis point equals one one-hundredth of a percentage point)
that may be specified in the applicable Prospectus Supplement as being
applicable to such Series, and the "Spread Multiplier" is the percentage that
may be specified in the applicable Prospectus Supplement as being applicable to
such Series, except that if so specified in the applicable Prospectus
Supplement, the Spread or Spread Multiplier on such Series of Floating Rate Debt
Units may be subject to adjustment from time to time in response to designated
changes in the rating assigned to such Debt Units by one or more rating
agencies, in accordance with a schedule or otherwise, all as described in such
Prospectus Supplement. The applicable Prospectus Supplement, unless otherwise
specified therein, will designate one of the following Base Rates as applicable
to a Floating Rate Debt Unit: (i) the CD Rate ("CD Rate Debt Unit"), (ii) the
Commercial Paper Rate ("Commercial Paper Rate Debt Unit"), (iii) the Federal
Funds Rate ("Federal Funds Rate Debt Unit"), (iv) LIBOR ("LIBOR Debt Unit"), (v)
the Prime Rate ("Prime Rate Debt Unit"), (vi) the Treasury Rate ("Treasury Rate
Debt Unit") or (vii) another Base Rate, as set forth in the applicable
Prospectus Supplement. The "Index Maturity" for any Series of Floating Rate Debt
Units is the period of maturity of the instrument or obligation from which the
Base Rate is calculated. "H.15(519)" means the publication entitled "Statistical
Release H.15(519), Selected Interest Rates", or any successor publication,
published by the Board of Governors of the Federal Reserve System. "Composite
Quotations" means the daily statistical release entitled "Composite 3:30 p.m.
Quotations for U.S. Government Securities", or any successor publication,
published by the Federal Reserve Bank of New York. Interest will be payable only
from cash received by the Trustee from the Deposited Assets or other assets
deposited in the Trust and available for application to such payment,
notwithstanding the accrual of interest on the Debt Unit Principal Balance at a
higher rate.

         As specified in the applicable Prospectus Supplement, Floating Rate
Debt Units of a given Series may also have either or both of the following (in
each case expressed as a rate per annum on a simple interest basis): (i) a
maximum limitation, or ceiling, on the rate at which interest may accrue during
any interest accrual period specified in the applicable Prospectus Supplement
("Maximum Debt Unit Rate") and (ii) a minimum limitation, or floor, on the rate
at which interest may accrue during any such interest accrual period ("Minimum
Debt Unit Rate"). In addition to any Maximum Debt Unit Rate that may be
applicable to any Series of Floating Rate Debt Units, the Debt Unit Rate
applicable to any Series of Floating Rate Debt Units will in no event be higher
than the maximum rate permitted by applicable New York and United States federal
law. Under applicable New York and United States federal law as of the date of
this Prospectus, the maximum rate of interest, with certain exceptions, is 25%
per annum on a simple interest basis.

         The Depositor will appoint, and enter into agreements with, agents
(each, a "Calculation Agent") to calculate Floating Debt Unit Rates on each
Series of Floating Rate Debt Units. The applicable Prospectus Supplement will
set forth the identity of the Calculation Agent for each Series of Floating Rate
Debt Units. All determinations of interest by the Calculation Agent shall, if
made on a commercially reasonable basis and in good faith, be conclusive for all
purposes and binding on the holders of Floating Rate Debt Units of a given
Series.

         The Floating Debt Unit Rate will be reset daily, weekly, monthly,
quarterly, semiannually or annually (such period being the "Interest Reset
Period", and the first day of each Interest Reset Period being an "Interest
Reset Date"), as specified in the applicable Prospectus Supplement. Interest
Reset Dates with respect to each Series will be specified in the applicable
Prospectus Supplement; provided that unless otherwise specified in such
Prospectus Supplement, the Debt Unit Rate in effect for the ten days immediately
prior to the Final Scheduled Distribution Date will be that in effect on the
tenth day preceding such Final Scheduled Distribution Date. If an Interest Reset
Date for any Series of Floating Rate Debt Units would otherwise be a day that is
not a Business Day, such Interest Reset Date will occur on the next Business
Day, except that, in the case of a LIBOR Debt Unit, if such Business Day would
fall in the next calendar month, such Interest Reset Date will be the
immediately preceding Business Day.

         Unless otherwise specified in the applicable Prospectus Supplement,
interest payable in respect of Floating Rate Debt Units shall be the accrued
interest from and including the Original Issue Date of such Series or the last
Interest Reset Date to which interest has accrued and been distributed, as the
case may be, to but excluding the immediately following Distribution Date. With
respect to a Floating Rate Debt Unit, accrued interest shall be calculated by
multiplying the Debt Unit Principal Balance of such Debt Unit by an accrued
interest factor. Such accrued interest factor will be computed by adding the
interest factors calculated for each day in the period for

                                       13

<PAGE>



which accrued interest is being calculated. Unless otherwise specified in the
applicable Prospectus Supplement, the interest factor (expressed as a decimal
calculated to seven decimal places without rounding) for each such day is
computed by dividing the Debt Unit Rate in effect on such day by 360, in the
case of LIBOR Debt Units, Commercial Paper Rate Debt Units, Federal Funds Rate
Debt Units, Prime Rate Debt Units and CD Rate Debt Units or by the actual number
of days in the year, in the case of Treasury Rate Debt Units. For purposes of
making the foregoing calculation, the variable Debt Unit Rate in effect on any
Interest Reset Date will be the applicable rate as reset on such date.

         Unless otherwise specified in the applicable Prospectus Supplement, all
percentages resulting from any calculation of the Debt Unit Rate on a Floating
Rate Debt Unit will be rounded, if necessary, to the nearest 1/100,000 of 1%
(.0000001), with five one-millionths of a percentage point rounded upward, and
all currency amounts used in or resulting from such calculation on Floating Rate
Debt Units will be rounded to the nearest one-hundredth of a unit (with .005 of
a unit being rounded upward).

         Interest on any Series of Floating Rate Debt Units will be
distributable on the Distribution Dates and for the interest accrual periods as
and to the extent set forth in the applicable Prospectus Supplement.

         The "Calculation Date", where applicable, pertaining to a Determination
Date will be the earlier of (i) the tenth calendar day after such Determination
Date or, if any such day is not a Business Day, the next succeeding Business Day
or (ii) the Business Day preceding the applicable Interest Payment Date.

         Upon the request of the holder of any Floating Rate Debt Unit of a
given Series, the Calculation Agent for such Series will provide the Debt Unit
Rate then in effect and, if determined, the Debt Unit Rate that will become
effective on the next Interest Reset Date with respect to such Floating Rate
Debt Unit.

         CD Rate Debt Units. CD Rate Debt Units will bear interest at the
interest rates (calculated with reference to the CD Rate and the Spread and/or
the Spread Multiplier, if any) specified in the applicable Prospectus
Supplement.

         The "CD Rate" means, with respect to any Determination Date, the rate
on such date for negotiable certificates of deposit having the applicable Index
Maturity, as published by the Board of Governors of the Federal Reserve System
in "Statistical Release H.15(519), Selected Interest Rates", or any successor
publication of the Board of Governors of the Federal Reserve System
("H.15(519)") under the heading "CDs (Secondary Market)". If such rate is not
published by 9:00 a.m., New York City time, on the Calculation Date pertaining
to such Determination Date, the CD Rate will be the rate on such Determination
Date for negotiable certificates of deposit of the applicable Index Maturity, as
published by the Federal Reserve Bank of New York in Composite Quotations, under
the heading "Debt Units of Deposit". If such rate is not published in Composite
Quotations by 3:00 p.m., New York City time, on the Calculation Date pertaining
to such Determination Date, then the CD Rate for such Determination Date will be
calculated by the Calculation Agent and will be the arithmetic mean of the
secondary market offered rates as of 10:00 a.m., New York City time, on such
Determination Date, of three leading nonbank dealers in negotiable U.S. dollar
certificates of deposit in The City of New York, selected by the Calculation
Agent after consultation with the Depositor, for negotiable certificates of
deposit of major United States money center banks of the highest credit standing
(in the market for negotiable certificates of deposit) with a remaining maturity
closest to the applicable Index Maturity in a denomination of $5,000,000;
provided that, if the dealers selected as aforesaid by the Calculation Agent are
not quoting such rates, the interest rate for the period commencing on the
Interest Reset Date following such Determination Date will be the interest rate
borne by such CD Rate Debt Units on such Determination Date.

         CD Rate Debt Units, like other Debt Units, are not deposit obligations
of a bank and are not insured by the Federal Deposit Insurance Corporation.

         Commercial Paper Rate Debt Units. Commercial Paper Rate Debt Units will
bear interest at the interest rates (calculated with reference to the Commercial
Paper Rate and the Spread and/or the Spread Multiplier, if any) specified in the
applicable Prospectus Supplement.


                                       14

<PAGE>



         The "Commercial Paper Rate" means, with respect to any Determination
Date, the Money Market Yield on such date of the rate for commercial paper
having the applicable Index Maturity, as published in H.15(519) under the
heading "Commercial Paper". If such rate is not published prior to 9:00 a.m.,
New York City time, on the Calculation Date pertaining to such Determination
Date, the Commercial Paper Rate will be the Money Market Yield on such
Determination Date of the rate for commercial paper of the applicable Index
Maturity, as published by the Federal Reserve Bank of New York in Composite
Quotations under the heading "Commercial Paper". If such rate is not published
in Composite Quotations by 3:00 p.m., New York City time, on the Calculation
Date pertaining to such Determination Date, then the Commercial Paper Rate for
such Determination Date will be calculated by the Calculation Agent and will be
the Money Market Yield of the arithmetic mean of the offered rates as of 11:00
a.m., New York City time, on such Determination Date of three leading dealers of
commercial paper in The City of New York, selected by the Calculation Agent
after consultation with the Depositor, for commercial paper of the applicable
Index Maturity, placed for industrial issuers whose bond rating (as determined
by a nationally recognized rating agency) is "AA" or the equivalent; provided
that, if the dealers selected as aforesaid by the Calculation Agent are not
quoting such rates, the interest rate for the period commencing on the Interest
Reset Date following such Determination Date will be the interest rate borne by
such Commercial Paper Rate Debt Units on such Determination Date.

         "Money Market Yield" will be a yield calculated in accordance with the
following formula:

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

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

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

         The "Federal Funds Rate" means, with respect to any Determination Date,
the rate on such date for federal funds, as published in H.15(519) under the
heading "Federal Funds (Effective)". If such rate is not published by 9:00 a.m.,
New York City time, on the Calculation Date pertaining to such Determination
Date, the Federal Funds Rate will be the rate on such Determination Date, as
published by the Federal Reserve Bank of New York in Composite Quotations under
the heading "Federal Funds/Effective Rate". If such rate is not published in
Composite Quotations by 3:00 p.m., New York City time, on the Calculation Date
pertaining to such Determination Date, then the Federal Funds Rate for such
Determination Date will be calculated by the Calculation Agent and will be the
arithmetic mean of the rates for the last transaction in overnight federal funds
arranged by three leading brokers of federal funds transactions in The City of
New York, selected by the Calculation Agent after consultation with the
Depositor, as of 9:00 a.m., New York City time, on such Determination Date;
provided that, if the brokers selected as aforesaid by the Calculation Agent are
not arranging such transactions, the interest rate for the period commencing on
the Interest Reset Date following such Determination Date will be the interest
rate borne by such Federal Funds Debt Units on such Determination Date.

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

         "LIBOR" means, with respect to any Determination Date, the rate
determined by the Calculation Agent in accordance with either clause (1) or
clause (2) below, as specified in the applicable Prospectus Supplement:

                  (1) The rate for deposits in U.S. dollars of the Index
         Maturity specified in the applicable Prospectus Supplement, commencing
         on the second London Banking Day immediately following such
         Determination Date, that appears on the Telerate Page 3750 as of 11:00
         a.m., London time, on such Determination Date ("LIBOR Telerate").
         "Telerate Page 3750" means the display designated as page "3750" on the
         Telerate Service (or such other page as may replace the page 3750 on
         that service or such

                                       15

<PAGE>



         other service or services as may be designated by the British Bankers'
         Association for the purpose of displaying London interbank offered
         rates for U.S. dollar deposits).

                  (2) The arithmetic mean of the offered rates for deposits in
         U.S. dollars having the Index Maturity specified in the applicable
         Prospectus Supplement, commencing on the second London Banking Day
         immediately following such Determination Date, that appear on the
         Reuters Screen LIBO Page as of 11:00 a.m., London time, on such
         Determination Date, if at least two such offered rates appear on the
         Reuters Screen LIBO Page ("LIBOR Reuters"). "Reuters Screen LIBO Page"
         means the display designated as Page "LIBO" on the Reuters Monitor
         Money Rate Service (or such other page as may replace the LIBO page on
         that service for the purpose of displaying London interbank offered
         rates of major banks).

         If neither LIBOR Telerate nor LIBOR Reuters is specified in the
applicable Prospectus Supplement, LIBOR will be determined as if LIBOR Telerate
had been specified.

         If (i) in the case where paragraph (1) above applies, no rate appears
on the Telerate Page 3750 or (ii) in the case where paragraph (2) above applies,
fewer than two offered rates appear on the Reuters Screen LIBO Page, LIBOR in
respect of such Determination Date will be determined by the Calculation Agent
on the basis of the rates at which deposits in U.S. dollars of the Index
Maturity specified in the applicable Prospectus Supplement are offered to prime
banks in the London interbank market at approximately 11:00 a.m., London time,
on such Determination Date by four major banks ("Reference Banks") in the London
interbank market, selected by the Calculation Agent, commencing on the second
London Banking Day immediately following such Determination Date in a principal
amount of not less than $1,000,000 that is representative for a single
transaction in such market at such time. The Calculation Agent will request the
principal London office of each of the Reference Banks to provide a quotation of
its rate. If at least two such quotations are provided, LIBOR for such
Determination Date will be the arithmetic mean of such quotations. If fewer than
two quotations are provided, LIBOR for such Determination Date will be the
arithmetic mean of the rates quoted at approximately 11:00 a.m., New York City
time, on such Determination Date by three major commercial or investment banks
(which may include Merrill Lynch & Co. or any of its affiliates) in The City of
New York, selected by the Calculation Agent, for U.S. dollar loans of the
applicable Index Maturity to leading European banks, commencing on the second
London Banking Day immediately following such Determination Date, in a principal
amount of not less than $1,000,000 that is representative for a single
transaction in such market at such time; provided that, if the banks selected as
aforesaid by the Calculation Agent are not quoting such rates, the interest rate
for the period commencing on the Interest Reset Date following such
Determination Date will be the interest rate borne by such LIBOR Notes on such
Determination Date.

         If any LIBOR Debt Unit is indexed to the offered rates for deposits in
a Specified Currency other than U.S. dollars, the applicable Prospectus
Supplement will set forth the method for determining such rates.

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

         The "Prime Rate" means, with respect to any Determination Date, the
rate on such date, as published in H.15(519) under the heading "Bank Prime
Loan". If such rate is not published by 9:00 a.m., New York City time, on the
Calculation Date pertaining to such Determination Date, the Prime Rate will be
determined by the Calculation Agent and will be the arithmetic mean of the rates
of interest publicly announced by each bank named on the "Reuters Screen NYMF
Page" as such bank's prime rate or base lending rate as in effect for such
Determination Date. "Reuters Screen NYMF Page" means the display designated as
page "NYMF" on the Reuters Monitor Money Rates Service (or such other page as
may replace the NYMF page on that service for the purpose of displaying prime
rates or base lending rates of major U.S. banks). If fewer than four but more
than one such rate appears on the Reuters Screen NYMF Page for such
Determination Date, the Prime Rate will be determined by the Calculation Agent
and will be the arithmetic mean of the prime rates, quoted on the basis of the
actual number of days in the year divided by 360, as of the close of business on
such Determination Date by four major money center banks in The City of New
York, selected by the Calculation Agent after consultation with the Depositor.
If fewer than two such rates appear on the Reuters Screen NYMF Page, the Prime
Rate will be calculated by the Calculation Agent and will be the arithmetic mean
of the prime rates in effect for such Determination Date as furnished in The
City

                                       16

<PAGE>



of New York by at least three substitute banks or trust companies organized and
doing business under the laws of the United States, or any state thereof, in
each case having total equity capital of at least $500,000,000 and subject to
supervision or examination by federal or state authority, selected by the
Calculation Agent after consultation with the Depositor; provided that, if the
banks or trust companies selected as aforesaid by the Calculation Agent are not
quoting such rates, the interest rate for the period commencing on the Interest
Reset Date following such Determination Date will be the interest rate borne by
such Prime Rate Debt Units on such Determination Date.

         Treasury Rate Debt Units. Treasury Rate Debt Units will bear interest
at the interest rates (calculated with reference to the Treasury Rate and the
Spread and/or the Spread Multiplier, if any) specified in the applicable
Prospectus Supplement.

         The "Treasury Rate" means, with respect to any Determination Date, the
rate for the auction held on such Determination Date of treasury bills of the
Index Maturity specified in the applicable Prospectus Supplement, as published
in H.15(519) under the heading "U.S. Government Securities--Treasury
bills-auction average (investment)". If such rate is not published by 9:00 a.m.,
New York City time, on the Calculation Date pertaining to such Determination
Date, the Prime Rate will be the auction average rate for such Determination
Date (expressed as a bond equivalent, rounded to the nearest one-hundredth of a
percent, with five one-thousandths of a percent rounded upward, on the basis of
a year of 365 or 366 days, as applicable, and applied on a daily basis) as
otherwise announced by the United States Department of the Treasury. In the
event that the results of the auction of treasury bills having the applicable
Index Maturity are not published or reported as provided above by 3:00 p.m., New
York City time, on such Calculation Date, or if no such auction is held on such
Determination Date, then the Treasury Rate will be calculated by the Calculation
Agent and will be a yield to maturity (expressed as a bond equivalent on the
basis of a year of 365 or 366 days, as applicable, and applied on a daily basis)
of the arithmetic mean of the secondary market bid rates, as of approximately
3:30 p.m., New York City time, on such Determination Date, of three leading
primary United States government securities dealers, selected by the Calculation
Agent after consultation with the Depositor, for the issue of treasury bills
with a remaining maturity closest to the applicable Index Maturity; provided
that, if the dealers selected as aforesaid by the Calculation Agent are not
quoting such rates, the interest rate for the period commencing on the Interest
Reset Date following such Determination Date will be the interest rate borne by
such Treasury Rate Debt Units on such Determination Date.

Principal of the Debt Units

         Unless the applicable Prospectus Supplement provides otherwise, each
Debt Unit (other than certain Classes of Strip Debt Units) will have a "Debt
Unit Principal Balance" which, at any time, will equal the maximum amount that
the holder thereof will be entitled to receive in respect of principal out of
the future cash flows on the Deposited Assets. Unless otherwise specified in the
applicable Prospectus Supplement, distributions generally will be applied to
undistributed accrued interest on, then to principal of, and then to premium (if
any) on, each such Debt Unit of the Class or Classes entitled thereto (in the
manner and priority specified in such Prospectus Supplement) until the aggregate
Debt Unit Principal Balance of such Class or Classes has been reduced to zero.
The outstanding Debt Unit Principal Balance of a Debt Unit will be reduced to
the extent of distributions of principal thereon, and, if applicable pursuant to
the terms of the related Series, by the amount of any net losses realized on any
Deposited Asset ("Realized Losses") allocated thereto. Unless the applicable
Prospectus Supplement provides otherwise, the initial aggregate Debt Unit
Principal Balance of Debt Units of a Series will equal the outstanding aggregate
principal balance of the related Deposited Assets as of the applicable Cut-off
Date. The initial aggregate Debt Unit Principal Balance of a Series will be
specified in the applicable Prospectus Supplement.

Optional Exchange

         The applicable Prospectus Supplement may provide that any of the
Depositor, Merrill Lynch & Co. or the Trustee, or their respective designees,
may exchange Debt Units of any given Series for a pro rata portion of the
Deposited Assets. The terms upon which a (or a specified) holder may exchange
such exchangeable Debt Units will be specified in the applicable Prospectus
Supplement; provided that (a) any right of exchange shall be exercisable only to
the extent that such exchange would not be inconsistent with continued
satisfaction of the applicable requirements for exemption under Rule 3a-7 under
the Investment Company Act of 1940, as amended, and all applicable rules,
regulations and interpretations thereunder and would not affect the
characterization of the Trust as a "grantor trust" for U.S. Federal income tax
purposes and (b) if the Deposited Assets constitute a pool of Underlying
Securities, any exercise of the Optional Exchange Right will be effected so
that, with respect to each series or issue of Underlying Securities included in
such pool (together with any related assets that credit enhance or otherwise
support that series or issue of Underlying Securities), the proportion that the
principal amount of such series or issue of Underlying Securities (together with
such related assets) bears to the aggregate principal amount of Debt Units
immediately prior to such exercise will be equal to the proportion that the
principal amount of such series or issue of Underlying Securities (together with
such related assets) bears to the aggregate principal amount of Debt Units
immediately after such exercise. See "Risk Factors--General Unavailability of
Optional Exchange".

         The applicable Prospectus Supplement will set forth the terms pursuant
to which a holder of exchangeable Debt Units may exercise an Optional Exchange
Right.

Call Right

         If one or more specified persons has the right to purchase all or a
portion of the Debt Units of any given Series, the applicable Prospectus
Supplement will designate such Series as a "Callable Series". The terms upon
which any such specified person or entity may exercise its right to purchase all
or a portion of the Debt Units of a Series will be specified in the applicable
Prospectus Supplement. Such terms may relate to, but are not limited to, the
following:

                  (a) a minimum Debt Unit Principal Balance with respect to each
         Debt Unit being purchased;

                  (b) a requirement that the Debt Unit Principal Balance of each
         Debt Unit being purchased be an integral multiple of an amount
         specified in the Prospectus Supplement;

                  (c) specified dates during which such a purchase may be
         effected; and

                  (d) the price or prices at which such a purchase may be
         effected (each, a "Call Price").

         After receiving notice of the exercise of such a call right, the
Trustee will provide notice thereof as specified in the applicable Prospectus
Supplement. Upon the satisfaction of any applicable conditions to the exercise
of such right to purchase the Debt Units described in such Prospectus
Supplement, each Debt Unitholder will be entitled to receive a distribution of a
pro rata share of the Call Price paid in connection with such exercise, in the
manner and to the extent described in such Prospectus Supplement.

Global Securities

         Unless otherwise specified in the applicable Prospectus Supplement, all
Debt Units of a given Series will, upon issuance, be represented by one or more
Global Securities that will be deposited with, or on behalf of, the Depositary,
and registered in the name of a nominee of the Depositary. Unless and until it
is exchanged in whole or in part for the individual Debt Units represented
thereby (each, a "Definitive Debt Unit"), a Global Security may not be
transferred except as a whole by the Depositary for such Global Security to a
nominee of such Depositary or by a nominee of such Depositary to such Depositary
or another nominee of such Depositary or by such Depositary or any such nominee
to a successor of such Depositary or a nominee of such successor.

         The Depository Trust Company has advised the Depositor as follows: The
Depository Trust Company is a limited-purpose trust company organized under the
laws of the State of New York, a member of the Federal Reserve System, a
"clearing corporation" within the meaning of the New York Uniform Commercial
Code, and a "clearing agency" registered pursuant to the provisions of Section
17A of the Exchange Act. The Depository Trust Company was created to hold
securities of its participants and to facilitate the clearance and settlement of
securities transactions among the institutions that have accounts with such
Depositary ("participants") in such securities through electronic book-entry
changes in accounts of the participants, thereby eliminating the need for
physical movement of securities certificates. Such Depositary's participants
include securities brokers and dealers (including Merrill Lynch & Co.), banks,
trust companies, clearing corporations and certain other organizations, some of
which (and/or their representatives) own such Depositary. Access to such
Depositary's book-entry system is also available to others, such as banks,
brokers, dealers and trust companies that clear through or maintain a custodial
relationship with a participant, either directly or indirectly. The Depository
Trust Company has confirmed to the Depositor that it intends to follow such
procedures.

         Upon the issuance of a Global Security, the Depositary for such Global
Security will credit, on its book-entry registration and transfer system, the
respective principal amounts of the individual Debt Units represented by such
Global Security to the accounts of its participants. The accounts to be
accredited shall be designated by the underwriters of such Debt Units, or, if
such Debt Units are offered and sold directly through one or more agents, by the
Depositor or such agent or agents. Ownership of beneficial interests in a Global
Security will be limited to participants or persons or entities that may hold
beneficial interests through participants. Ownership of beneficial interests in
a Global Security will be shown on, and the transfer of that ownership will be
effected only through, records maintained by the Depositary for such Global
Security or by participants or persons or entities that hold through
participants. The laws of some states require that certain purchasers of
securities take physical delivery of such securities. Such limits and such laws
may limit the market for beneficial interests in a Global Security.

         So long as the Depositary for a Global Security, or its nominee, is the
owner of such Global Security, such Depositary or such nominee, as the case may
be, will be considered the sole Debt Unitholder of the individual Debt Units
represented by such Global Security for all purposes under the Trust Agreement
governing such Debt Units. Except as set forth below, owners of beneficial
interests in a Global Security will not be entitled to have individual Debt
Units represented by such Global Security registered in their names, will not
receive or be entitled to receive physical delivery of any such Debt Units and
will not be considered the Debt Unitholders thereof under the Trust Agreement
governing such Debt Units. Because the Depositary can only act on behalf of its
participants, the ability of a holder of any Debt Unit to pledge that Debt Unit
to persons or entities that do not participate in the Depositary's system, or to
otherwise act with respect to such Debt Unit, may be limited due to the lack of
a physical certificate for such Debt Unit.

         Distributions of principal of (and premium, if any) and any interest on
individual Debt Units represented by a Global Security will be made to the
Depositary or its nominee, as the case may be, as the Debt Unitholder of such
Global Security. None of the Depositor, the Trustee for such Debt Units, any
Paying Agent or the Debt Unit Registrar for such Debt Units will have
responsibility or liability for any aspect of the records relating to or
payments made on account of beneficial interests in such Global Security or for
maintaining, supervising or reviewing any records relating to such beneficial
interests.

         The Depositor expects that the Depositary for Debt Units of a given
Series, upon receipt of any distribution of principal, premium or interest in
respect of a definitive Global Security representing any of such Debt Units,
will immediately credit participants' accounts with payments in amounts
proportionate to their respective beneficial interests in the principal amount
of such Global Security as shown on the records of such Depositary. The
Depositary also expects that payments by participants to owners of beneficial
interests in such Global Security held through such participants will be
registered in "street name" and will be the responsibility of such participants.

         If the Depositary for Debt Units of a given Series is at any time
unwilling or unable to continue as depository and a successor depository is not
appointed by the Depositor within 90 days, the Depositor will issue individual
Definitive Debt Units in exchange for the Global Security or Securities
representing such Debt Units. In addition, the Depositor may at any time and in
its sole discretion determine not to have any Debt Units of a given

                                       19

<PAGE>



Series represented by one or more Global Securities and, in such event, will
issue Definitive Debt Units of such Series in exchange for the Global Security
or Securities representing such Debt Units. Further, if the Depositor so
specifies with respect to the Debt Units of a given Series, an owner of a
beneficial interest in a Global Security representing Debt Units of such Series
may, on terms acceptable to the Depositor and the Depositary for such Global
Security, receive individual Definitive Debt Units in exchange for such
beneficial interest. In any such instance, an owner of a beneficial interest in
a Global Security will be entitled to physical delivery of individual Definitive
Debt Units of the Series represented by such Global Security equal in principal
amount to such beneficial interest and to have such Definitive Debt Units
registered in its name. Individual Definitive Debt Units of such Series so
issued will be issued in denominations, unless otherwise specified by the
Depositor, of $1,000 and integral multiples thereof.

         The applicable Prospectus Supplement will set forth any specific terms
of the depository arrangement with respect to any Series of Debt Units being
offered thereby to the extent not set forth or different from the description
set forth above.


                         DESCRIPTION OF DEPOSITED ASSETS

General

         Each Series of Debt Units (or, if more than one Class exists, each
Class within such Series) will represent in the aggregate the entire beneficial
ownership interest in a publicly traded debt, or other eligible, security issued
pursuant to an effective registration statement filed with the Commission or a
pool of such securities (the "Underlying Securities"), together with other
assets (which may include guarantees, letters of credit, financial insurance,
interest rate and/or currency swaps and other derivative transactions that
credit enhance or otherwise support the Underlying Securities) designed to
assure the servicing or timely distribution of payments to holders of the Debt
Units, all as described in the applicable Prospectus Supplement (such assets,
together with the Underlying Securities, the "Deposited Assets"). If the
Underlying Securities represent obligations issued by one or more Underlying
Securities Issuers, such Underlying Securities will satisfy certain Eligibility
Criteria described below under "Underlying Securities Issuer". The Underlying
Securities will be purchased in the secondary market and, correspondingly, will
not be acquired from any Underlying Securities Issuer (whether as part of any
distribution by or pursuant to any agreement with such Underlying Securities
Issuer or otherwise). The Underlying Securities will represent direct
obligations of one or more corporations or other business entities organized
under the laws of the United States or any state thereof, which are subject to
the informational requirements of the Exchange Act and which, in accordance
therewith, file reports and other information with the Commission. No Underlying
Securities Issuer will participate in the offering of the Debt Units, nor will
an Underlying Securities Issuer receive any of the proceeds from the sale of
Underlying Securities or from the issuance of the Debt Units.

         This Prospectus relates only to the Debt Units offered hereby and does
not relate to the Underlying Securities. The following description of the
Underlying Securities and the Underlying Securities Issuer is intended only to
summarize material characteristics of the Underlying Securities that the
Depositor is permitted to deposit in a Trust and does not purport to be a
complete description of any prospectus relating to Underlying Securities or of
any Underlying Securities Indenture (as defined below).

         The applicable Prospectus Supplement will describe the material terms
of the Deposited Assets, including the material terms of any derivative
instruments that are included in the Deposited Assets.

Underlying Securities Issuer

         The Underlying Securities Issuers will be either corporations or other
business entities organized under the laws of the United States or any state
thereof, which are subject to the informational requirements of the Exchange Act
and which, in accordance therewith, file reports and other information with the
Commission. In the event that any Trust consists of 10% or more of the
securities of a particular Underlying Securities Issuer, the applicable
Prospectus Supplement will include audited financial statements of such
Underlying Securities Issuer; provided that if (i) such Underlying Securities
Issuer is eligible to use Form S-3 for a primary stock offering and (ii) the

                                       20

<PAGE>



Underlying Securities were not acquired from the issuer thereof nor will such
issuer receive any proceeds from the sale of the Underlying Securities to the
Depositor, then the applicable Prospectus Supplement will only reference the
periodic reports filed with the Commission by such Underlying Securities Issuer,
which periodic reports should be reviewed by any prospective Debt Unitholder of
the Trust containing such Underlying Securities. See "Risk Factors--Need to
Obtain Information Concerning Underlying Securities Issuers".

         Reports and information referred to in the preceding paragraph may be
inspected and copied at the public reference facilities maintained by the
Commission at 450 Fifth Street, N.W., Washington, D.C. 20549, and at the
following Regional Offices of the Commission: New York Regional Office, Room
1100, 7 World Trade Center, New York, New York 10048 and Chicago Regional
Office, Suite 1400, Northwestern Atrium Center, 500 West Madison Street, Suite
1400, Chicago, Illinois 60661-2511, and copies of such material can be obtained
from the Public Reference Section of the Commission, Washington, D.C. 20549, at
prescribed rates. Such material may also be accessed electronically by means of
the Commission's home page on the Internet at http://www.sec.gov.

         WITH RESPECT TO ANY UNDERLYING SECURITIES, A PROSPECTIVE DEBT
UNITHOLDER SHOULD OBTAIN AND EVALUATE THE SAME INFORMATION CONCERNING THE
RELEVANT UNDERLYING SECURITIES ISSUER AS IT WOULD OBTAIN AND EVALUATE IF IT WERE
INVESTING DIRECTLY IN THE UNDERLYING SECURITIES OR IN THE ISSUER THEREOF.

         None of the Depositor, the Trustee, Merrill Lynch & Co. or any of their
affiliates assumes any responsibility for the accuracy or completeness of any
publicly available information concerning any Underlying Securities Issuer
(including, without limitation, any investigation as to its financial condition
or creditworthiness) or concerning any Underlying Securities (whether or not
such information is filed with the Commission) or otherwise considered by a
purchaser of the Debt Units in making its investment decision in connection
therewith; provided that the foregoing shall not apply to any information
concerning the Underlying Securities and any Underlying Securities Issuer that
is expressly set forth in this Prospectus or an applicable Prospectus Supplement
(i.e., Identifying Information, information of the type described in an
applicable Prospectus Supplement under "Description of the Underlying
Securities--General" and "Description of the Underlying Securities--Indenture"
and as to whether Concentrated Underlying Securities and the related Underlying
Securities Issuer meet the "Eligibility Criteria" described above).

Indenture

         General. Unless otherwise specified in the applicable Prospectus
Supplement, each Underlying Security will have been issued pursuant to an
agreement (each, an "Indenture") between the Underlying Securities Issuer and a
trustee (the "Underlying Securities Trustee"). The Indenture and the Underlying
Securities Trustee will be qualified under the Trust Indenture Act of 1939 (the
"Trust Indenture Act") and the Indenture will contain certain provisions
required by the Trust Indenture Act.

         Certain Covenants. Indentures generally contain covenants intended to
protect security holders against the occurrence or effects of certain specified
events, including restrictions limiting the issuer's, and in some cases one or
more of the issuer's subsidiaries', ability to: (i) consolidate, merge, or
transfer or lease assets; (ii) incur or suffer to exist any lien, charge or
encumbrance upon all or some specified portion of its property or assets, or to
incur, assume, guarantee or suffer to exist any indebtedness for borrowed money
if the payment of such indebtedness is secured by the grant of such a lien; or
(iii) declare or pay any cash dividends, or make any distributions on or in
respect of, or purchase, redeem, exchange or otherwise acquire or retire for
value, any capital stock or subordinated indebtedness of the issuer or its
subsidiaries, if any. An indenture may also contain financial covenants which,
among other things, require the maintenance of certain financial ratios or the
creation or maintenance of reserves or permit certain actions to be taken only
if compliance with such covenants can be demonstrated at the time the actions
are to be taken. Subject to certain exceptions, indentures typically may be
amended or supplemented and past defaults may be waived with the consent of the
indenture trustee, the consent of the holders of not less than a specified
percentage of the outstanding securities, or both.

         The Indenture related to one or more Underlying Securities included in
a Trust may include some, all or none of the foregoing provisions or variations
thereof, together with additional covenants not discussed herein. The

                                       21

<PAGE>



Underlying Securities, if not rated investment grade, generally will be subject
to more extensive restrictive covenants. In any event, there can be no assurance
that any type of Underlying Securities will be subject to any such covenants or
that any such covenants will protect the Trust as a holder of the Underlying
Securities against losses. The Prospectus Supplement used to offer any Series of
Debt Units will describe material covenants in relation to any Concentrated
Underlying Security (as defined below) and, as applicable, will describe
material covenants which are common to any pool of Underlying Securities. Any
material risk factors associated with non-investment grade Underlying Securities
deposited into a Trust will be set forth in the applicable Prospectus
Supplement.

         Events of Default. Indentures generally provide that any one of a
number of specified events will constitute an event of default with respect to
the securities issued thereunder. Such events of default typically include the
following or variations thereof: (i) failure by the issuer to pay an installment
of interest or principal on the securities at the time required (subject to any
specified grace period) or to redeem any of the securities when required
(subject to any specified grace period); (ii) failure by the issuer to observe
or perform any covenant, agreement or condition contained in the securities or
the indenture which failure is materially adverse to security holders and
continues for a specified period after notice thereof is given to the issuer by
the indenture trustee or the holders of not less than a specified percentage of
the outstanding securities; (iii) failure by the issuer and/or one or more of
its subsidiaries to make any required payment of principal (and premium, if any)
or interest with respect to other material outstanding debt obligations or the
acceleration by or on behalf of the holders of such securities; and (iv) certain
events of bankruptcy or insolvency with respect to the issuer and/or one or more
of its subsidiaries.

         Remedies. Indentures generally provide that upon the occurrence of an
event of default, the indenture trustee may, and upon the written request of the
holders of not less than a specified percentage of the outstanding securities
the indenture trustee must, take such action as it may deem appropriate to
protect and enforce the rights of the security holders. Certain indentures
provide that the indenture trustee or a specified percentage of the holders of
the outstanding securities have the right to declare all or a portion of the
principal and accrued interest on the outstanding securities immediately due and
payable upon the occurrence of certain events of default, subject to the
issuer's right to cure, if applicable. Generally, an indenture will contain a
provision entitling the trustee thereunder to be indemnified by the security
holders prior to proceeding to exercise any right or power under such indenture
with respect to such securities at the request of such security holders. An
indenture is also likely to limit a security holder's right to institute certain
actions or proceedings to pursue any remedy under the indenture unless certain
conditions are satisfied, including obtaining the consent of the indenture
trustee, that the proceeding be brought for the ratable benefit of all holders
of the security and/or that the indenture trustee, after being requested to
institute a proceeding by the owners of at least a specified minimum percentage
of the securities, shall have refused or neglected to comply with such request
within a reasonable time.

         Each Indenture may include some, all or none of the foregoing
provisions or variations thereof, together with additional events of default
and/or remedies not discussed herein. The Prospectus Supplement with respect to
any Series of Debt Units will describe the events of default under the Indenture
with respect to any Concentrated Underlying Security and applicable remedies
with respect thereto. With respect to any Trust comprising a pool of securities,
the applicable Prospectus Supplement will describe certain common Underlying
Security Events of Default with respect to such pool. There can be no assurance
that any such provision will protect the Trust, as a holder of the Underlying
Securities, against losses. Furthermore, a Debt Unitholder will have no
independent legal right to exercise any remedies with respect to the Underlying
Securities and will be required to rely on the Trustee of the applicable Trust
to pursue any available remedies on behalf of the relevant Debt Unitholders in
accordance with the terms of the Trust Agreement. If an Underlying Security
Event of Default occurs and the Trustee as a holder of the Underlying Securities
is entitled to vote or take such other action to declare the principal amount of
an Underlying Security and any accrued and unpaid interest thereon to be due and
payable, the Debt Unitholders' objectives may differ from those of holders of
other securities of the same series and class as any Underlying Security in
determining whether to require the acceleration of the Underlying Securities.

         Subordination. If specified in the applicable Prospectus Supplement,
certain of the Underlying Securities with respect to any Trust may be either
senior ("Senior Underlying Securities") or subordinated ("Subordinated
Underlying Securities") in right to payment to other existing or future
indebtedness of the Underlying Securities Issuer. With respect to Subordinated
Underlying Securities, to the extent of the subordination provisions of such

                                       22

<PAGE>



securities,and after the occurrence of certain events, security holders and
direct creditors whose claims are senior to Subordinated Underlying Securities,
if any, may be entitled to receive payment of the full amount due thereon before
the holders of any subordinated debt securities are entitled to receive payment
on account of the principal (and premium, if any) or any interest on such
securities. Consequently, the Trust as a holder of subordinated debt may suffer
a greater loss than if it held unsubordinated debt of the Underlying Securities
Issuer. There can be no assurance, however, that in the event of a bankruptcy or
similar insolvency proceeding the Trust as a holder of Senior Underlying
Securities would receive all payments in respect of such securities even if
holders of subordinated securities receive no amounts in respect of such
securities. Reference is made to the Prospectus Supplement used to offer any
Series of Debt Units for a description of any subordination provisions with
respect to any Concentrated Underlying Securities and the percentage of Senior
Underlying Securities and Subordinated Underlying Securities, if any, in a Trust
comprised of a pool of securities.

         Secured Obligations. Certain of the Underlying Securities with respect
to any Trust may represent secured obligations of the Underlying Securities
Issuer ("Secured Underlying Securities"). Generally, unless an event of default
shall have occurred, or with respect to certain collateral or as otherwise set
forth in the indenture pursuant to which such securities were issued, an issuer
of secured obligations has the right to remain in possession and retain
exclusive control of the collateral and to collect, invest and dispose of any
income related to the collateral. The indenture pursuant to which any secured
indebtedness is issued may also contain certain provisions for release,
substitution or disposition of collateral under certain circumstances with or
without the consent of the indenture trustee or upon the direction of not less
than a specified percentage of the security holders. The indenture pursuant to
which any secured indebtedness is issued typically will also provide for the
disposition of the collateral upon the occurrence of certain events of default
with respect thereto. In the event of a default in respect of any secured
obligation, security holders may experience a delay in payments on account of
principal (and premium, if any) or any interest on such securities pending the
sale of any collateral and prior to or during such period the related collateral
may decline in value. If proceeds of the sale of collateral following an
indenture event of default are insufficient to repay all amounts due in respect
of any secured obligations, the holders of such securities (to the extent not
repaid from the proceeds of the sale of the collateral) would have only an
unsecured claim ranking pari passu with the claims of all other general
unsecured creditors.

         The Indenture with respect to Secured Underlying Securities may include
some, all or none of the foregoing provisions or variations thereof. The
Prospectus Supplement used to offer any Series of Debt Units that includes
Concentrated Underlying Securities which are Secured Underlying Securities will
describe the material security provisions of such Underlying Securities and the
related collateral. With respect to any Trust composed of a pool of securities,
a substantial portion of which are Secured Underlying Securities, the applicable
Prospectus Supplement will disclose certain material information with respect to
such security provisions and the collateral.

Principal Terms of Underlying Securities

         Reference is made to the applicable Prospectus Supplement with respect
to each Series of Debt Units for a description of the following terms, as
applicable, of any Concentrated Underlying Security: (i) the title and series of
such Underlying Securities, and the aggregate principal amount, denomination and
form thereof; (ii) whether such securities are senior or subordinated to any
other existing or future obligations of the Underlying Securities Issuer; (iii)
whether any of the obligations are secured and the nature of any collateral;
(iv) the limit, if any, upon the aggregate principal amount of such securities;
(v) the dates on which, or the range of dates within which, the principal of
(and premium, if any, on) such securities will be payable; (vi) the rate or
rates, or the method of determination thereof, at which such Underlying
Securities will bear interest, if any ("Underlying Securities Rate"); the date
or dates from which such interest will accrue; and the dates on which such
interest will be payable; (vii) the obligation, if any, of the Underlying
Securities Issuer to redeem such Underlying Securities and other securities of
the same class or series pursuant to any sinking fund or similar provisions, or
at the option of a holder thereof, and the periods within which or the dates on
which, the prices at which and the terms and conditions upon which such
securities may be redeemed or repurchased, in whole or in part, pursuant to such
obligation; (viii) the periods within which or the dates on which, the prices at
which and the terms and conditions upon which such securities may be redeemed,
if any, in whole or in part, at the option of the Underlying Securities Issuer;
(ix) whether the Underlying Securities were issued at a price lower than the
principal amount thereof; (x) if other than United States dollars, the currency
in which such securities are denominated, or in which payment of the principal
of (and

                                       23

<PAGE>



premium, if any) or any interest on such Underlying Securities will be made, and
the circumstances, if any, when such currency of payment may be changed; (xi)
material events of default or restrictive covenants provided for with respect to
such Underlying Securities; (xii) the rating thereof, if any; (xiii) the
principal United States market on which the Underlying Securities are traded, if
any; and (xiv) any other material terms of such Underlying Securities.


         With respect to a Trust comprised of a pool of Underlying Securities,
the applicable Prospectus Supplement will describe the composition of the
Underlying Securities pool as of the Cut-off Date, certain material events of
default or restrictive covenants common to the Underlying Securities, and, on an
aggregate, percentage or weighted average basis, as applicable, the
characteristics of the pool with respect to the terms set forth in subclauses
(ii), (iii), (v), (vi), (vii), (viii), (ix) and (x) of the preceding paragraph
and any other material terms regarding such pool of securities.

         Other than publicly traded Debt Securities which satisfy the necessary
requirements set forth herein with respect to Underlying Securities, the
Underlying Securities may consist of publicly traded securities that are
primarily serviced by the cashflows of (x) a discrete pool of receivables or
other financial assets, either fixed or revolving, that by their terms convert
into cash within a finite time period or (y) other assets designed to assure the
servicing or timely distribution of proceeds to the securityholders. In
particular, such other eligible securities may include, or be similar in
structure to, trust originated preferred securities ("TOPrS"(sm)). (Trust
Originated Preferred Securities and TOPrS are service marks of Merrill Lynch &
Co.)

         If an issuer of Concentrated Underlying Securities ceases to file
periodic reports under the Exchange Act, the Depositor will continue to be
subject to the reporting requirements of the Exchange Act but certain
information with respect to such obligor may be unavailable. In such an event,
if so required pursuant to applicable law or if so provided in the applicable
Prospectus Supplement, the Depositor will instruct the Trustee of the relevant
Trust to sell all of such Concentrated Underlying Securities and to distribute
the proceeds from such sale to the Debt Unitholders in accordance with the
Allocation Ratio; any such sale will result in a loss to the Debt Unitholders of
the relevant Series if the sale price is less than the purchase price for such
Concentrated Underlying Securities. Otherwise, if so provided in the applicable
Prospectus Supplement, the Depositor will instruct the Trustee of the relevant
Trust to distribute such Concentrated Underlying Securities in accordance with
the Allocation Ratio.

Other Deposited Assets

         In addition to the Underlying Securities, the Depositor may arrange to
be deposited into a given Trust, or the Trustee on behalf of the Debt
Unitholders of a Trust may enter into an agreement constituting or providing for
the purchase of, to the extent described in the applicable Prospectus
Supplement, other assets (such as guarantees, letters of credit, financial
insurance, and hedging contracts or other similar arrangements, including
without limitation puts and calls, interest rate swaps, currency swaps, floors,
caps and collars, and options on each of the foregoing, cash and assets
ancillary or incidental to the foregoing or to the Underlying Securities
(including assets obtained through foreclosure or in settlement of claims with
respect thereto) and direct obligations of the United States) designed to assure
the servicing or timely distribution of payments to holders of the Debt Units,
all as described in the applicable Prospectus Supplement. With respect to any
such other assets that are material to the amount or timing of payments on the
Debt Units of any Series, the applicable Prospectus Supplement will contain a
description of the material terms thereof and, if relevant, information relating
to any obligor thereon or issuer thereof.

         Unless otherwise specified in the applicable Prospectus Supplement, the
Deposited Assets for a given Series of Debt Units and the related Trust will not
constitute Deposited Assets for any other Series of Debt Units and the related
Trust, and the Debt Units of a given Series will possess an equal and ratable
undivided ownership interest in such Deposited Assets. The applicable Prospectus
Supplement may, however, specify that certain assets constituting a part of the
Deposited Assets relating to any given Series may be beneficially owned solely
by or deposited solely for the benefit of one Class or a group of Classes within
such Series. In such event, the other Classes of such Series will not possess
any beneficial ownership interest in those specified assets constituting a part
of the Deposited Assets.


                                       24

<PAGE>



Credit Support

         As specified in the applicable Prospectus Supplement for a given Series
of Debt Units, the Trust for any Series of Debt Units may include, or the Debt
Unitholders of such Series (or any Class or group of Classes within such Series)
may have the benefit of, Credit Support for any Class or group of Classes within
such Series. Such Credit Support may be provided by any combination of the
following means described below or any other means described in the applicable
Prospectus Supplement. The applicable Prospectus Supplement will set forth
whether the Trust for any Class or group of Classes of Debt Units contains, or
the Debt Unitholders of such Debt Units have the benefit of, Credit Support and,
if so, the amount, type and other relevant terms of each element of Credit
Support with respect to any such Class or Classes and certain information with
respect to the obligors of each such element, including financial information
with respect to any such obligor providing Credit Support for 20% or more of the
aggregate principal amount of such Class or Classes.

         Subordination. As discussed below under "--Collections", the rights of
the Debt Unitholders of any given Class within a Series of Debt Units to receive
collections from the Trust for such Series and any Credit Support obtained for
the benefit of the Debt Unitholders of such Series (or Classes within such
Series) may be subordinated to the rights of the Debt Unitholders of one or more
other Classes of such Series to the extent described in the applicable
Prospectus Supplement. Such subordination accordingly provides some additional
credit support to those Debt Unitholders of those other Classes. For example, if
losses are realized during a given period on the Deposited Assets relating to a
Series of Debt Units such that the collections received thereon are insufficient
to make all distributions on the Debt Units of such Series, those realized
losses would be allocated to the Debt Unitholders of any Class of any such
Series that is subordinated to another Class, to the extent and in the manner
provided in the applicable Prospectus Supplement. In addition, if so provided in
the applicable Prospectus Supplement, certain amounts otherwise payable to Debt
Unitholders of any Class that is subordinated to another Class may be required
to be deposited into a reserve account. Amounts held in any reserve account may
be applied as described below under "--Reserve Accounts" and in the applicable
Prospectus Supplement.

         If so provided in the applicable Prospectus Supplement, the Credit
Support for any Series or Class of Debt Units may include, in addition to the
subordination of certain Classes of such Series and the establishment of a
reserve account, any of the other forms of Credit Support described below. Any
such other forms of Credit Support that are solely for the benefit of a given
Class will be limited to the extent necessary to make required distributions to
the Debt Unitholders of such Class or as otherwise specified in the applicable
Prospectus Supplement. In addition, if so provided in the applicable Prospectus
Supplement, the obligor of any other forms of Credit Support may be reimbursed
for amounts paid pursuant to such Credit Support out of amounts otherwise
payable to one or more of the Classes of the Debt Units of such Series. Further,
payments to be made in respect of any forms of Credit Support arranged for on
behalf of the Debt Unitholders may be required to be paid prior to any
distributions that are required to be made to Debt Unitholders.

         Letter of Credit; Surety Bond. The Debt Unitholders of any Series (or
Class or group of Classes of Debt Units within such Series) may, if specified in
the applicable Prospectus Supplement, have the benefit of a letter or letters of
credit (a "Letter of Credit") issued by a bank (a "Letter of Credit Bank") or a
surety bond or bonds (a "Surety Bond") issued by a surety company (a "Surety").
In either case, the Trustee or such other person specified in the applicable
Prospectus Supplement will use its reasonable efforts to cause the Letter of
Credit or the Surety Bond, as the case may be, to be obtained, to be kept in
full force and effect (unless coverage thereunder has been exhausted through
payment of claims) and to pay timely the fees or premiums therefor unless, as
described in the applicable Prospectus Supplement, the payment of such fees or
premiums is otherwise provided for. The Trustee or such other person specified
in the applicable Prospectus Supplement will make or cause to be made draws
under the Letter of Credit or the Surety Bond, as the case may be, under the
circumstances and to cover the amounts specified in the applicable Prospectus
Supplement. Any amounts otherwise available under the Letter of Credit or the
Surety Bond will be reduced to the extent of any prior unreimbursed draws
thereunder. The applicable Prospectus Supplement will provide the manner,
priority and source of funds by which any such draws are to be repaid.

         Unless otherwise specified in the applicable Prospectus Supplement, in
the event that the Letter of Credit Bank or the Surety, as applicable, ceases to
satisfy any credit rating or other applicable requirements specified in

                                       25

<PAGE>



the applicable Prospectus Supplement, the Trustee or such other person specified
in the applicable Prospectus Supplement will use its reasonable efforts to
obtain or cause to be obtained a substitute Letter of Credit or Surety Bond, as
applicable, or other form of credit enhancement providing similar protection,
that meets such requirements and provides the same coverage to the extent
available for the same cost. There can be no assurance that any Letter of Credit
Bank or any Surety, as applicable, will continue to satisfy such requirements or
that any such substitute Letter of Credit, Surety Bond or similar credit
enhancement will be available providing equivalent coverage for the same cost.
To the extent not so available, the credit support otherwise provided by the
Letter of Credit or the Surety Bond (or similar credit enhancement) may be
reduced to the level otherwise available for the same cost as the original
Letter of Credit or Surety Bond.

         Reserve Accounts. If so provided in the applicable Prospectus
Supplement, the Trustee or such other person specified in the Prospectus
Supplement will deposit or cause to be deposited into an account maintained with
an eligible institution (which may be the Trustee) (a "Reserve Account") any
combination of cash or permitted investments in specified amounts, which will be
applied and maintained in the manner and under the conditions specified in such
Prospectus Supplement. In the alternative or in addition to such deposit, a
Reserve Account may be funded through application of a portion of collections
received on the Deposited Assets for a given Series of Debt Units, in the manner
and priority specified in the applicable Prospectus Supplement. Amounts may be
distributed to Debt Unitholders of such Class or group of Classes within such
Series, or may be used for other purposes, in the manner and to the extent
provided in the applicable Prospectus Supplement. Amounts deposited in any
Reserve Account will be invested in certain permitted investments by, or at the
direction of, the Trustee, the Depositor or such other person as may be
specified in the applicable Prospectus Supplement.

Collections

         The Trust Agreement will establish procedures by which the Trustee or
such other person as may be specified in the Prospectus Supplement is obligated,
for the benefit of the Debt Unitholders of each Series of Debt Units, to
administer the related Deposited Assets, including making collections of all
payments made thereon, depositing from time to time prior to any applicable
Distribution Date such collections into a segregated trust account maintained or
controlled by the applicable Trustee for the benefit of such Series (each a
"Debt Unit Account"). An Administrative Agent, if any is appointed pursuant to
the applicable Prospectus Statement, will direct the Trustee, and otherwise the
Trustee will make all determinations, as to the appropriate application of such
collections and other amounts available for distribution to the payment of any
administrative or collection expenses (such as the administrative fee) and
certain Credit Support-related ongoing fees (such as insurance premiums, letter
of credit fees or any required account deposits) and to the payment of amounts
then due and owing on the Debt Units of such Series (and Classes within such
Series), all in the manner and priorities described in the applicable Prospectus
Supplement. The applicable Prospectus Supplement will specify the collection
periods, if applicable, and Distribution Dates for a given Series of Debt Units
and the particular requirements relating to the segregation and investment of
collections received on the Deposited Assets during a given collection period or
on or by certain specified dates. There can be no assurance that amounts
received from the Deposited Assets and any Credit Support obtained for the
benefit of Debt Unitholders for a particular Series or Class of Debt Units over
a specified period will be sufficient, after payment of all prior expenses and
fees for such period, to pay amounts then due and owing to holders of such Debt
Units. The applicable Prospectus Supplement will also set forth the manner and
priority by which any Realized Loss will be allocated among the Classes of any
Series of Debt Units, if applicable.

         The relative priorities of distributions with respect to collections
from the assets of the Trust assigned to Classes of a given Series of Debt Units
may permanently or temporarily change over time upon the occurrence of certain
circumstances specified in the applicable Prospectus Supplement. Moreover, the
applicable Prospectus Supplement may specify that the relative distribution
priority assigned to each Class of a given Series for purposes of payments of
certain amounts, such as principal, may be different from the relative
distribution priority assigned to each such Class for payments of other amounts,
such as interest or premium.

                       DESCRIPTION OF THE TRUST AGREEMENT

         General. The following summary of material provisions of the Trust
Agreement does not purport to be complete, and such summary is qualified in its
entirety by reference to the detailed provisions of the form of Trust Agreement
filed as an exhibit to the Registration Statement. Article and section
references in parentheses below are to articles and sections in the Standard
Terms for Trust Agreements. Wherever particular sections or defined terms of the
Standard Terms for Trust Agreements are referred to, such sections or defined
terms are incorporated herein by reference as part of the statement made, and
the statement is qualified in its entirety by such reference.

Assignment of Deposited Assets

         At the time of issuance of any Series of Debt Units, the Depositor will
cause the Underlying Securities and the Deposited Assets specified in the
Prospectus Supplement, if any, to be assigned and delivered to the Trustee to be
deposited in the related Trust, together with all principal, premium (if any)
and interest received by or on behalf of the Depositor on or with respect to
such Underlying Securities and other Deposited Assets after the cut-off date
specified in the Prospectus Supplement (the "Cut-off Date"), other than
principal, premium (if any) and interest due on or before the Cut-off Date and
other than any Retained Interest. Concurrently with such assignment, the
Depositor will execute, and the Trustee will authenticate and deliver, the Debt
Units to the Depositor in exchange for the Underlying Securities and other
Deposited Assets, if any. Each Deposited Asset will be identified in a schedule
to the Trust Agreement. Such schedule will include certain summary identifying
information with respect to each Underlying Security and each other Deposited
Asset as of the Cut-off Date. Such schedule will include, to the extent
applicable, information regarding the payment terms of any Concentrated
Underlying Security, the Retained Interest, if any, with respect thereto, the
maturity or terms thereof, the rating, if any, thereof and any other material
information with respect thereto.

         In addition, the Depositor will, with respect to each Deposited Asset,
deliver or cause to be delivered to the Trustee (or to the custodian hereinafter
referred to) all documents necessary to transfer ownership of such Deposited
Asset to the Trustee. The Trustee (or such custodian) will hold such documents
in trust for the benefit of the Debt Unitholders.

         The Depositor will make certain representations and warranties
regarding its authority to enter into, and its ability to perform its
obligations under, the Trust Agreement. Upon a breach of any such representation
of the Depositor which materially and adversely affects the interests of the
Debt Unitholders, the Depositor will be obligated to cure the breach in all
material respects.

Collection and Other Administrative Procedures

         General. With respect to any Series of Debt Units, the Trustee or such
other person specified in the Prospectus Supplement, directly or through
sub-administrative agents, will establish and maintain certain accounts for the
benefit of the holders of the relevant Debt Units and will deposit in such
accounts all amounts received by it in respect of the Deposited Assets. The
Trustee on behalf of the Trust may direct any depository institution maintaining
such accounts to invest the funds in such accounts in one or more eligible
investments bearing interest or sold at a discount. Except as otherwise provided
in the applicable Series Supplement, any earnings with respect to such
investments will be paid to, and any losses with respect to such investments
will be solely for the account of, the Debt Unitholders (and, if applicable, the
holder of the Retained Interest) in proportion to their interest in the invested
funds. Further, the Trustee or such other person specified in the Prospectus
Supplement, directly or through sub-administrative agents, will make reasonable
efforts to collect all scheduled payments under the Deposited Assets and will
follow or cause to be followed such collection procedures, if any, as it would
follow with respect to comparable financial assets that it held for its own
account, provided that such procedures are consistent with the Trust Agreement
and any related instrument governing any Credit Support and provided further
that, except as otherwise expressly set forth in the applicable Prospectus
Supplement, it shall not be required to expend or risk its own funds or
otherwise incur personal financial liability.

         Sub-Administration. The Trustee or the Administrative Agent, if any,
may enter into agreements (each, a "Sub-Administration Agreement") with one or
more agents meeting the qualifications set forth in the Trust

                                       27

<PAGE>



Agreement (each, a "Sub-Administrative Agent") in order to delegate certain of
its administrative obligations in respect of the Deposited Assets to such
Sub-Administrative Agents, provided that the Trustee or Administrative Agent
will remain obligated with respect to its obligations under the Trust Agreement.
Each Sub-Administrative Agent will be required to perform the customary
functions of an administrator of comparable financial assets, including, if
applicable, collecting payments from obligors and remitting such collections to
the Trustee; maintaining accounting records relating to the Deposited Assets,
attempting to cure defaults and delinquencies; and enforcing any other remedies
with respect thereto all as and to the extent provided in the applicable
Sub-Administration Agreement.

         Each Sub-Administration Agreement will be consistent with the terms of
the Trust Agreement, and any such delegation to a Sub-Administrative Agent will
not be permitted if it would result in a withdrawal or downgrading of the rating
of the relevant Series of Debt Units issued pursuant to the Trust Agreement.
With respect to any Sub-Administration Agreement between an Administrative Agent
and a Sub-Administrative Agent, although each such Sub-Administration Agreement
will be a contract solely between such Administrative Agent and the
Sub-Administrative Agent, the Trust Agreement pursuant to which a Series of Debt
Units is issued will provide that, if for any reason such Administrative Agent
for such Series of Debt Units is no longer acting in such capacity, the Trustee
or any successor Administrative Agent must recognize the Sub-Administrative
Agent's rights and obligations under such Sub-Administration Agreement.

         The Trustee or Administrative Agent, as applicable, will be solely
liable for all fees owed by it to any Sub-Administrative Agent, irrespective of
whether the compensation of the Trustee, pursuant to the Trust Agreement with
respect to the particular Series of Debt Units, is sufficient to pay such fees.
However, a Sub-Administrative Agent may be entitled to a Retained Interest in
certain Deposited Assets to the extent provided in the applicable Prospectus
Supplement. Each Sub-Administrative Agent will be reimbursed by the Trustee or
the Administrative Agent for certain expenditures which it makes, generally to
the same extent the Trustee would be reimbursed under the terms of the Trust
Agreement relating to such Series. See "Trustee Compensation and Payment of
Expenses".

         The Administrative Agent or Trustee, as applicable, may require any
Sub-Administrative Agent to agree to indemnify the Administrative Agent or
Trustee, as applicable, for any liability or obligation sustained by the
Administrative Agent or Trustee, as applicable, in connection with any act or
failure to act by the Sub-Administrative Agent.

         Realization upon Defaulted Deposited Assets. Unless otherwise specified
in the applicable Prospectus Supplement, as administrator with respect to the
Deposited Assets, the Trustee, on behalf of the Debt Unitholders of a given
Series (or any Class or Classes within such Series), will present claims under
each applicable Credit Support Instrument and will take such reasonable steps as
are necessary to receive payment or to permit recovery thereunder with respect
to defaulted Deposited Assets. As set forth above, all collections by or on
behalf of the Trustee or Administrative Agent under any Credit Support
Instrument are to be deposited in the Debt Unit Account for the related Trust,
subject to withdrawal as described above.

         Unless otherwise provided in the applicable Prospectus Supplement, the
Trustee will be obligated to follow or cause to be followed such normal
practices and procedures as it deems necessary or advisable to realize upon any
defaulted Deposited Asset; provided that, except as otherwise expressly provided
in the applicable Prospectus Supplement, it will not be required to expend or
risk its own funds or otherwise incur financial liability. If the proceeds of
any liquidation of the defaulted Deposited Asset are less than the sum of (i)
the outstanding principal balance of the defaulted Deposited Asset, (ii)
interest accrued but unpaid thereon at the applicable interest rate and (iii)
the aggregate amount of expenses incurred by the Trustee in connection with such
proceedings to the extent reimbursable from the assets of the Trust under the
Trust Agreement, the Trust for the applicable Series will realize a loss in the
amount of such difference. Only if and to the extent provided in the applicable
Prospectus Supplement, the Administrative Agent or Trustee, as so provided, will
be entitled to withdraw or cause to be withdrawn from the related Debt Unit
Account out of the net proceeds recovered on any defaulted Deposited Asset,
prior to the distribution of such proceeds to Debt Unitholders, amounts
representing its normal administrative compensation on the Deposited Asset,
unreimbursed administrative expenses incurred with respect to the Deposited
Asset and any unreimbursed advances of delinquent payments made with respect to
the Deposited Asset.

Retained Interest

         The Prospectus Supplement for a Series of Debt Units will specify
whether there will be any Retained Interest in the Deposited Assets, and, if so,
the owner thereof. If so provided, the Retained Interest will be established on
an asset-by-asset basis and will be specified in an exhibit to the applicable
series supplement to the Trust Agreement. A Retained Interest in a Deposited
Asset represents a specified ownership interest therein and a right to a portion
of the payments thereon. Payments in respect of the Retained Interest will be
deducted from payments on the Deposited Assets as received and, in general, will
not be deposited in the applicable Debt Unit Account or become a part of the
related Trust. Unless otherwise provided in the applicable Prospectus
Supplement, after deduction of all applicable fees as provided for in the Trust
Agreement, the Trustee will allocate on a pari passu basis any partial recovery
on an Underlying Security between the Retained Interest (if any) and the Debt
Unitholders of the applicable Series.

         The applicable Prospectus Supplement will specify the Administrative
Agent's compensation, if any, and the Trustee's compensation, and the source,
manner and priority of payment thereof, with respect to a given Series of Debt
Units.

         If and to the extent specified in the applicable Prospectus Supplement,
in addition to amounts payable to any Sub-Administrative Agent, the
Administrative Agent, if any, and otherwise the Trustee will pay from its
compensation certain expenses incurred in connection with its administration of
the Deposited Assets, including, without limitation, payment of the fees and
disbursements of the Trustee, if applicable, and independent accountants,
payment of expenses incurred in connection with distributions and reports to
Debt Unitholders, and payment of any other expenses described in the applicable
Prospectus Supplement.

Advances in Respect of Delinquencies

         Unless otherwise specified in the applicable Prospectus Supplement, the
Administrative Agent, if any, specified therein will have no obligation to make
any advances with respect to collections on the Deposited Assets or in favor of
the Debt Unitholders of the related Series of Debt Units. However, to the extent
provided in the applicable Prospectus Supplement, any such Administrative Agent
will advance on or before each Distribution Date its own funds or funds held in
the Debt Unit Account for such Series that are not part of the funds available
for distribution for such Distribution Date, in an amount equal to the aggregate
of payments of principal, premium (if any) and interest (net of related
Administration Fee and any Retained Interest) with respect to the Deposited
Assets that were due during the related Collection Period and were delinquent on
the related Determination Date, subject to (i) any such Administrative Agent's
good faith determination that such advances will be reimbursable from Related
Proceeds (as defined below) and (ii) such other conditions as may be specified
in the Prospectus Supplement.

         Advances are intended to maintain a regular flow of scheduled interest,
premium (if any) and principal payments to holders of the Class or Classes of
Debt Units entitled thereto, rather than to guarantee or insure against losses.
Unless otherwise provided in the applicable Prospectus Supplement, advances of
an Administrative Agent's funds, if any, will be reimbursable only out of
related recoveries on the Deposited Assets (and amounts received under any form
of Credit Support) for such Series with respect to which such advances were made
(as to any Deposited Assets, "Related Proceeds"); provided, however, that any
such advance will be reimbursable from any amounts in the Debt Unit Accounts for
such Series to the extent that such Administrative Agent shall determine, in its
sole judgment, that such advance is not ultimately recoverable from Related
Proceeds. If advances have been made by such Administrative Agent from excess
funds in the Debt Unit Account for any Series, such Administrative Agent will
replace such funds in such Debt Unit Account on any future Distribution Date to
the extent that funds in such Debt Unit Account on such Distribution date are
less than payments required to be made to Debt Unitholders on such date. If so
specified in the applicable Prospectus Supplement, the obligations, if any, of
an Administrative Agent to make advances may be secured by a cash advance
reserve fund or a surety bond. If applicable, information regarding the
characteristics of, and the identity of any obligor on, any such surety bond
will be set forth in the applicable Prospectus Supplement.



                                       29

Certain Matters Regarding the Administrative Agent and the Depositor

         An Administrative Agent, if any, for each Series of Debt Units under
the Trust Agreement will be named in the applicable Prospectus Supplement. The
entity serving as Administrative Agent for any such Series may be the Trustee,
the Depositor, an affiliate of either thereof, the Deposited Asset Provider or
any third party and may have other business relationships with the Trustee, the
Depositor, their affiliates or the Deposited Asset Provider.

         The Trust Agreement will provide that an Administrative Agent may
resign from its obligations and duties under the Trust Agreement with respect to
any Series of Debt Units only if such resignation, and the appointment of a
successor, will not result in a withdrawal or downgrading of the rating of any
Class of Debt Units of such Series or upon a determination that its duties under
the Trust Agreement with respect to such Series are no longer permissible under
applicable law. No such resignation will become effective until the Trustee or a
successor has assumed the Administrative Agent's obligations and duties under
the Trust Agreement with respect to such Series.

         The Trust Agreement will further provide that neither such
Administrative Agent, the Depositor nor any director, officer, employee, or
agent or the Administrative Agent or the Depositor will incur any liability to
the related Trust or Debt Unitholders for any action taken, or for refraining
from taking any action, in good faith pursuant to the Trust Agreement or for
errors in judgment; provided, however, that none of the Administrative Agent,
the Depositor nor any such person will be protected against any liability that
would otherwise be imposed by reason of willful misfeasance, bad faith or gross
negligence in the performance of duties thereunder or by reason of reckless
disregard of obligations and duties thereunder. The Trust Agreement will further
provide that, unless otherwise provided in the applicable series supplement
thereto, such an Administrative Agent, the Depositor and any director, officer,
employee or agent of the Administrative Agent or the Depositor will be entitled
to indemnification by the related Trust and will be held harmless against any
loss, liability or expense incurred in connection with any legal action relating
to the Trust Agreement or the Debt Units, other than any loss, liability or
expense incurred by reason of willful misfeasance, bad faith or gross negligence
in the performance of duties thereunder or by reason of reckless disregard of
obligations and duties thereunder. In addition, the Trust Agreement will provide
that neither such an Administrative Agent nor the Depositor will be under any
obligation to appear in, prosecute or defend any legal action which is not
incidental to their respective responsibilities under the Trust Agreement or
which in its opinion may involve it in any expense or liability. Each of such
Administrative Agent or the Depositor may, however, in its discretion undertake
any such action which it may deem necessary or desirable with respect to the
Trust Agreement and the rights and duties of the parties thereto and the
interests of the Debt Unitholders thereunder. The applicable Prospectus
Supplement will describe how such legal expenses and costs of such action and
any liability resulting therefrom will be allocated.

         Any person into which an Administrative Agent may be merged or
consolidated, or any person resulting from any merger of consolidation to which
an Administrative Agent is a part, or any person succeeding to the business of
an Administrative Agent, will be the successor of the Administrative Agent under
the Trust Agreement with respect to the Debt Units of a Series.

Administrative Agent Termination Events; Rights upon Administrative Agent
Termination Event

         Unless otherwise provided in the applicable Prospectus Supplement,
"Administrative Agent Termination Events" under the Trust Agreement with respect
to any given Series of Debt Units will consist of the following: (i) any failure
by an Administrative Agent to remit to the Trustee any funds in respect of
collections on the Deposited Assets and Credit Support, if any, as required
under the Trust Agreement, that continues unremedied for five days after the
giving of written notice of such failure to the Administrative Agent by the
Trustee or the Depositor, or to the Administrative Agent, the Depositor and the
Trustee by the holders of such Debt Units evidencing not less than 25% of the
Voting Rights (as defined below); (ii) any failure by an Administrative Agent
duly to observe or perform in any material respect any of its other covenants or
obligations under the Trust Agreement with respect to such Series which
continues unremedied for thirty days after the giving of written notice of such
failure to the Administrative Agent by the Trustee or the Depositor, or to the
Administrative Agent, the Depositor and the Trustee by the holders of such Debt
Units evidencing not less than 25% of the Voting Rights; and (iii) certain
events of insolvency, readjustment of debt, marshalling of assets and
liabilities or similar proceedings and certain actions by or on behalf of an
Administrative Agent indicating its insolvency or inability to

                                       30

<PAGE>



pay its obligations. Any additional Administrative Agent Termination Events with
respect to any given Series of Debt Units will be set forth in the applicable
Prospectus Supplement. In addition, the applicable Prospectus Supplement and the
related series supplement to the Trust Agreement will specify as to each matter
requiring the vote of holders of Debt Units of a Class or group of Classes
within a given Series, the circumstances and manner in which the Required
Percentage (as defined below) applicable to each such matter is calculated.
"Required Percentage" means, with respect to any matter requiring a vote of
holders of Debt Units of a given Series, the specified percentage (computed on
the basis of outstanding Debt Unit Principal Balance or Notional Amount, as
applicable) of Debt Units of a designated Class or group of Classes within such
Series (either voting as separate classes or as a single class) applicable to
such matter, all as specified in the applicable Prospectus Supplement and the
related series supplement to the Trust Agreement. "Voting Rights" evidenced by
any Debt Unit will be the portion of the voting rights of all the Debt Units in
the related Series allocated in the manner described in the applicable
Prospectus Supplement.

         Unless otherwise specified in the applicable Prospectus Supplement, so
long as an Administrative Agent Termination Event under the Trust Agreement with
respect to a given Series of Debt Units remains unremedied, the Depositor or the
Trustee may, and at the direction of holders of such Debt Units evidencing not
less than the Required Percentage of the Voting Rights, the Trustee will,
terminate all rights and obligations of such Administrative Agent under the
Trust Agreement relating to the applicable Trust and in and to the related
Deposited Assets (other than any Retained Interest of such Administrative
Agent), whereupon the Trustee will succeed to all the responsibilities, duties
and liabilities of such Administrative Agent under the Trust Agreement with
respect to such Series (except that if the Trustee is prohibited by law from
obligating itself to make advances regarding delinquent Deposited Assets, then
the Trustee will not be so obligated) and will be entitled to similar
compensation arrangements. In the event that the Trustee is unwilling or unable
to act, it may or, at the written request of the holders of such Debt Units
evidencing not less than the Required Percentage of the Voting Rights, it will
appoint, or petition a court of competent jurisdiction for the appointment of,
an Administrative Agent acceptable to the Rating Agency with a net worth at the
time of such appointment of at least $15,000,000 to act as successor to such
Administrative Agent under the Trust Agreement with respect to such Series.
Pending such appointment, the Trustee is obligated to act in such capacity
(except that if the Trustee is prohibited by law from obligating itself to make
advances regarding delinquent Deposited Assets, then the Trustee will not be so
obligated). The Trustee and any such successor may agree upon the compensation
to be paid to such successor, which in no event may be greater than the
compensation payable to such Administrative Agent under the Trust Agreement with
respect to such Series.

         No Debt Unitholder will have the right under the Trust Agreement to
institute any proceeding with respect thereto unless such holder previously has
given to the Trustee written notice of breach and unless the holders of Debt
Units evidencing not less than the Required Percentage of the Voting Rights have
made written request upon the Trustee to institute such proceeding in its own
name as trustee thereunder and have offered to the Trustee reasonable indemnity,
and the Trustee for fifteen days has neglected or refused to institute any such
proceeding. The Trustee, however, is under no obligation to exercise any of the
trusts or powers vested in it by the Trust Agreement or to make any
investigation of matters arising thereunder to institute, conduct or defend any
litigation thereunder or in relation thereto at the request, order or direction
of any of the holders of Debt Units covered by the Trust Agreement, unless such
Debt Unitholders have offered to the Trustee reasonable security or indemnity
against the costs, expenses and liabilities which may be incurred therein or
thereby.

Trustee Compensation and Payment of Expenses

         The applicable Prospectus Supplement will specify the Trustee's
compensation, and the source, manner and priority of payment thereof, with
respect to a given Series of Debt Units.

         The applicable Series Supplement may provide for the payment by the
Depositor of certain Prepaid Ordinary Expenses of the Trustee. If the Prepaid
Ordinary Expenses set forth in the Series Supplement are greater than zero, the
Trustee will be deemed to agree that the payment of such amount constitutes full
and final satisfaction of and payment for all Ordinary Expenses. If the Prepaid
Ordinary Expenses set forth in the Series Supplement are zero, the Series
Supplement may indicate that Ordinary Expenses will be paid for by the Trust, in
which case the Trustee will be paid on a periodic basis by the Trust or the
Retained Interest at the rate or amount and on the

                                       31

<PAGE>



terms provided for in the Series Supplement. The Trustee has agreed, pursuant to
the Trust Agreement, that its right to receive such payments from the Trust will
constitute full and final satisfaction of and payment for all Ordinary Expenses
and that the Trustee will have no claim on payment of Ordinary Expenses from any
other source, including the Depositor. If the Prepaid Ordinary Expenses set
forth in the Series Supplement are zero, the Series Supplement may provide that
the Depositor will pay to the Trustee from time to time a fee for its services
and expenses as trustee as set forth in the Series Supplement payable at the
times set forth therein. The Trustee will agree, pursuant to the Trust
Agreement, that its right to receive such payments from the Depositor will
constitute full and final satisfaction of and payment for all Ordinary Expenses
and that the Trustee will have no claim for payment of Ordinary Expenses from
the Trust. The Trustee has further agreed that, notwithstanding any failure by
the Depositor to make such periodic payments of Ordinary Expenses, the Trustee
will continue to perform its obligations under the Trust Agreement. The
Depositor's obligations to pay Ordinary Expenses under the Trust Agreement will
be extinguished and of no further effect upon he payment of Ordinary Expenses
due and owing on the termination of the Trust pursuant to the terms of the Trust
Agreement.

         Subject to the terms of the Trust Agreement, all Extraordinary Expenses
(as defined in the Trust Agreement), to the extent not paid by a third party,
are obligations of the Trust, and when due and payable will be satisfied solely
by the Trust.

         The Trustee will not take any action, including appearing in,
instituting or conducting any action or suit under the Trust Agreement or in
relation thereto which, in the Trustee's opinion, would or might cause it to
incur costs, expenses or liabilities that are Extraordinary Expenses unless (i)
the Trustee is satisfied that it will have adequate security or indemnity in
respect of such costs, expenses and liabilities, (ii) the Trustee has been
instructed to do so by Debt Unit holders representing not less than the Required
Percentage (as defined in the Trust Agreement) of the aggregate principal amount
of Debt Units then outstanding, and (iii) the Debt Unit holders, pursuant to the
instructions given under clause (ii) above, have agreed that such costs,
expenses or liabilities will either be (x) paid by the Trustee from the Trust,
in the case of a vote of 100% of the aggregate principal amount of Debt Units
then outstanding, or (y) paid by the Trustee (which payment will be made out of
its own funds and not from monies on deposit in the Trust), in which case the
Trustee will be entitled to receive, upon demand, reimbursement from those Debt
Unitholders who have agreed to bear the entire amount of such costs, expenses or
liabilities on a pro rata basis among such Debt Unitholders.

Distributions on Debt Units

         The distribution of interest and principal on Debt Units issued in
registered form will be made (i) if the Debt Units are held in book-entry form,
to the relevant book-entry depository, which will credit the relevant
participant's account at such book-entry depository in accordance with the
policies and procedure of such book-entry depository or (ii) if the Debt Units
are not held in book-entry form, at the corporate trust office of the Trustee as
specified in the Trust Agreement or, at the option of the Trustee, by check
mailed to the address of the Person entitled thereto as such address appears in
the Debt Unit register. Subject to the terms and conditions of the Trust
Agreement, with respect to Debt Units not held in book-entry form and having the
minimum wire denomination specified in the Trust Agreement, such payment will be
made by wire transfer of immediately available funds to the account designated
by the holder in a written request received by the Trustee not later than 10
days prior to the relevant distribution date; provided that, if a wire transfer
cannot be made for any reason, payment will be made by check. The Trustee will
not be required to send federal funds wires until any corresponding payments
which were not same day funds when received by it have become same day funds.

         Unless specified otherwise in a Series Supplement, the final
distribution of principal, interest and/or premium will be made upon
presentation and surrender of such Debt Units at the corporate trust office of
the Trustee as specified in the Trust Agreement.

Optional Exchange

         The terms and conditions, if any, upon which Debt Units of any Series
may be exchanged for a pro rata portion of the Underlying Securities of the
related Trust will be specified in the related Series Supplement; provided that
any right of exchange will be exercisable only to the extent that the Depositor
provides upon the Trustee's

                                       32

<PAGE>



request an opinion of counsel that (i) such exchange would not be inconsistent
with the Depositor's and the Trustee's continued satisfaction of the applicable
requirements under the Investment Company Act of 1940, as amended, and (ii) such
exchange would not affect the characterization of the Trust as a "grantor trust"
for United States federal income tax purposes.

         Any tender of a Debt Unit by the holder thereof for exchange will be
irrevocable. Unless otherwise provided in the applicable Series Supplement, the
exchange option may be exercised by the holder of a Debt Unit for less than the
aggregate principal amount of such Debt Unit as long as the aggregate principal
amount outstanding after such exchange is an authorized denomination and all
other exchange requirements set forth in the related Series Supplement are
satisfied. Upon such partial exchange, such Debt Unit will be cancelled and a
new Debt Unit or Debt Units for the remaining principal amount of the Debt Unit
will be issued (which, in the case of any Debt Unit issued in registered form,
will be in the name of the holder of such exchanged Debt Unit).

Voting Rights with Respect to Underlying Securities

         Within five Business Days after receipt of notice of any meeting of, or
other occasion for the exercise of voting rights or the giving of consents by,
owners of any of the Underlying Securities, the Trustee will give notice to the
Debt Unitholders, setting forth (i) such information as is contained in such
notice to owners of Underlying Securities, (ii) a statement that the Debt
Unitholders will be entitled, subject to any applicable provision of law and any
applicable provisions of such Underlying Securities, to instruct the Trustee as
to the exercise of voting rights, if any, pertaining to such Underlying
Securities and (iii) a statement as to the manner in which instructions may be
given to the Trustee to give a discretionary proxy to a person designated in the
notice received by the Trustee. The Trustee will give such notice to the Debt
Unitholders of record on the relevant record date.

         Upon the written request of the applicable Debt Unitholder, received on
or before the date established by the Trustee for such purpose, the Trustee will
endeavor, insofar as practicable and permitted under any applicable provision of
law and any applicable provision of or governing the Underlying Securities, to
vote in accordance with any nondiscretionary instruction set forth in such
written request. The Trustee will not vote except as specifically authorized and
directed in written instructions from the applicable Debt Unitholder entitled to
give such instructions. Notwithstanding the foregoing, if the Trustee determines
(based upon advice furnished by nationally recognized independent tax counsel,
whether at the request of any Debt Unitholder or otherwise) that the exercise of
voting rights with respect to any Underlying Securities could result in a "sale
or other disposition" of such Underlying Securities within the meaning of
Section 1001(a) of the Internal Revenue Code of 1986, as amended (the "Code"),
the Trustee will exercise such voting rights in a manner that would not result
in any such sale or other disposition. The Trustee will have no responsibility
to make any such determination.

         Unless otherwise specified in the applicable Series Supplement, the
voting rights allocable to the owners of the Underlying Securities pursuant to
the terms thereof will be allocated among the Debt Unitholders pro rata, in the
proportion that the denomination of each Debt Unit bears to the aggregate
denomination of all Debt Units. By accepting delivery of a Debt Unit, whether
upon original issuance or subsequent transfer, exchange or replacement thereof,
and without regard to whether ownership is beneficial or otherwise, the Debt
Unitholder agrees so long as it is an owner of such Debt Unit that it will not
grant any consent (i) to any conversion of the timing of payment of, or the
method or rate of accruing, interest on the Underlying Securities underlying the
Debt Units held by such Debt Unitholder or (ii) to any redemption or prepayment
of the Underlying Securities underlying the Debt Units held by such Debt
Unitholder. The Trustee will not grant any consent solicited from the owners of
the Underlying Securities underlying the Debt Units with respect to the matters
set forth in Section 5.15(c) of the Trust Agreement nor will it accept or take
any action in respect of any consent, proxy or instructions received from any
Debt Unitholder in contravention of the provisions of such Section.

Limitations on Rights of Debt Unitholders

         No Debt Unitholder will have the right under the Trust Agreement to
institute any proceeding with respect to the Trustee or the Trust unless such
holder previously has given to the Trustee written notice of breach and unless
(i) such holder has previously given to the Trustee a written notice of breach
and of the continuance thereof, (ii) the holders of Debt Units of such Series
evidencing not less than the Required Percentage of the Voting Rights of

                                       33

<PAGE>



such Series have made written request upon the Trustee to institute such
proceeding in its own name as Trustee thereunder and have offered to the Trustee
reasonable indemnity, (iii) the Trustee for 15 days has neglected or refused to
institute any such proceeding and (iv) no direction inconsistent with such
written request has been given to the Trustee during such 15-day period by Debt
Unitholders evidencing not less than the Required Percentage of the aggregate
Voting Rights of such Series. The Trustee, however, is under no obligation to
exercise any of the trusts or powers vested in it by the Trust Agreement or to
make any investigation of matters arising thereunder or to institute, conduct or
defend any litigation thereunder or in relation thereto at the request, order or
direction of any of the holders of Debt Units covered by the Trust Agreement,
unless such Debt Unitholders have offered to the Trustee reasonable security or
indemnity against the costs, expenses and liabilities which may be incurred
therein or thereby.

Modification and Waiver

         Unless otherwise specified in the applicable Prospectus Supplement, the
Trust Agreement may be amended from time to time by the Depositor and the
Trustee without notice to or the consent of any of the Debt Unitholders for any
of the following purposes: (i) to cure any ambiguity; (ii) to correct or
supplement any provision therein which may be inconsistent with any other
provision therein or in the Prospectus Supplement; (iii) to appoint a change in
Trustee for a Series of Debt Units subsequent to the Closing Date for such
Series; (iv) to provide for administration of separate Trusts by more than one
trustee; (v) to provide for a successor Trustee with respect to Debt Units of
one or more Series; (vi) to provide for the issuance of a new Series of Debt
Units pursuant to a Supplement; (vii) to add or supplement any Credit Support
for the benefit of any Debt Unitholders (provided that if any such addition
affects any series or class of Debt Unitholders differently than any other
series or class of Debt Unitholders, then such addition will not, as evidenced
by an opinion of counsel, have a material adverse effect on the interests of any
affected series or class of Debt Unitholders; (viii) to add to the covenants,
restrictions or obligations of the Depositor, the Administrative Agent, if any,
or the Trustee for the benefit of the Debt Unitholders; (ix) to add, change or
eliminate any other provisions with respect to matters or questions arising
under such Trust Agreement so long as (x) any such addition, change or
elimination will not, as evidenced by an opinion of counsel, affect the tax
status of the Trust or result in a sale or exchange of any Debt Unit for tax
purposes and (y) the Trustee has received written confirmation from each Rating
Agency rating such Debt Units that such amendment will not cause such Rating
Agency to reduce or withdraw the then current rating thereof; or (x) to comply
with any requirements imposed by the Code. Without limiting the generality of
the foregoing, unless otherwise specified in the applicable Prospectus
Supplement, the Trust Agreement may also be modified or amended from time to
time by the Depositor and the Trustee, with the consent of the holders of Debt
Units evidencing not less than the Required Percentage of the Voting Rights of
those Debt Units that are materially adversely affected by such modification or
amendment for the purpose of adding any provision to or changing in any manner
or eliminating any provision of the Trust Agreement or of modifying in any
manner the rights of such Debt Unitholders; provided, however, that in the event
such modification or amendment would materially adversely affect the rating of
any Series or Class by each Rating Agency, the Required Percentage specified in
the related series supplement to the Trust Agreement shall include an additional
specified percentage of the Debt Units of such Series or Class.

         Without limiting the generality of the foregoing, unless otherwise
specified in the applicable Prospectus Supplement, the Trust Agreement may also
be modified or amended from time to time by the Depositor and the Trustee with
the consent of the holders of Debt Units evidencing not less than the required
percentage to amend the Voting Rights of those Debt Units that are materially
adversely affected by such modification or amendment for the purpose of adding
any provision to or changing in any manner or eliminating any provision of the
Trust Agreement or of modifying in any manner the rights of such Debt
Unitholders; provided that no such amendment will (i) reduce in any manner the
amount of, or delay the timing of, payments received on Deposited Assets which
are required to be distributed on any Debt Unit without the consent of the
holders of such Debt Units or (ii) reduce the percentage of aggregate Voting
Rights required to take any action specified in the Trust Agreement, without the
consent of the holders of all Debt Units of such Series or Class then
Outstanding.

         Unless otherwise specified in the applicable Prospectus Supplement,
holders of Debt Units evidencing not less than the required percentage to waive
the Voting Rights of a given Series may, on behalf of all Debt Unitholders of
that Series, (i) waive, insofar as that Series is concerned, compliance by the
Depositor or the Trustee

                                       34

<PAGE>



with certain restrictive provisions, if any, of the Trust Agreement before the
time for such compliance and (ii) waive any past default under the Trust
Agreement with respect to Debt Units of that Series, except a default in the
failure to distribute amounts received as principal of (and premium, if any) or
any interest on any such Debt Unit and except a default in respect of a covenant
or provision the modification or amendment of which would require the consent of
the holder of each outstanding Debt Unit affected thereby.

Reports to Debt Unitholders; Notices

         Reports to Debt Unitholders. Unless otherwise provided in the
applicable Prospectus Supplement, with each distribution to Debt Unitholders of
a Series, the Trustee will forward or cause to be forwarded to each such Debt
Unitholder, to the Depositor and to such other parties as may be specified in
the Trust Agreement, a statement setting forth:

                  (i) the amounts received by the Trustee as of the last such
         statement in respect of principal, interest and premium on the
         Underlying Securities and any amounts received by the Trustee with
         respect to any derivatives transaction entered into by the Trust
         pursuant to the terms of the Trust Agreement;

                  (ii) any amounts payable by the Trust as of such date pursuant
         to any derivatives transaction entered into by the Trust pursuant to
         the terms of the Trust Agreement;

                  (iii) the amount of compensation received by the
         Administrative Agent, if any, and the Trustee for the period relating
         to such Distribution Date, and such other customary information as the
         Administrative Agent, if any, or otherwise the Trustee deems necessary
         or desirable to enable Debt Unitholders to prepare their tax returns;

                  (iv) if the Prospectus Supplement provides for advances, the
         aggregate amount of advances included in such distribution, and the
         aggregate amount of unreimbursed advances at the close of business on
         such Distribution Date;

                  (v) the amount of such distribution allocable to principal of
         and premium, if any, and interest on the Debt Units of such Series, and
         the amount of aggregate unpaid interest accrued as of such Distribution
         Date;

                  (vi) in the case of Debt Units bearing interest on a floating
         rate basis, the respective floating rate applicable to such Debt Units
         on such Distribution Date, as calculated in accordance with the method
         specified in such Debt Units and the related Series Supplement;

                  (vii) such other customary information as the Trustee deems
         necessary or desirable (or that any such Debt Unitholder reasonably
         requests in writing) to enable such Debt Unitholders to prepare their
         tax returns;

                  (viii) if the Series Supplement provides for Advances (as
         defined in the Trust Agreement), the aggregate amount of Advances, if
         any, included in such distribution, and the aggregate amount of
         unreimbursed Advances, if any, at the close of business on such
         Distribution Date;

                  (ix) the aggregate stated principal amount and, if applicable,
         notional amount of the Underlying Securities related to such Series,
         the current rating assigned by the applicable rating agency thereon and
         the current interest rate or rates thereon at the close of business on
         such Distribution Date;

                  (x) the aggregate principal amount (or notional amount, if
         applicable) of each Series at the close of business on such
         distribution date, separately identifying any reduction in such
         aggregate principal amount (or notional amount) due to the allocation
         of certain realized losses on such Distribution Date or otherwise, as
         provided in the Trust Agreement; and


                                       35

<PAGE>



                  (xi) as to any Series for which credit support has been
         obtained, the amount or notional amount of coverage of each element of
         Credit Support (and rating, if any, thereof) included therein as of the
         close of business on such Distribution Date.

         In the case of information furnished pursuant to subclauses (i), (ii),
(iii), (v) and (vii) above, the amounts will be expressed as a U.S. dollar
amount (or equivalent thereof in any other specified currency) per minimum
denomination of Debt Units or for such other specified portion thereof. Within a
reasonable period of time after the end of each calendar year, the Trustee will
furnish to each person who at any time during the calendar year was a Debt
Unitholder a statement containing the information set forth in subclauses (i),
(ii), (iii), (v) and (vii) above, aggregated for such calendar year or the
applicable portion thereof during which such person was a Debt Unitholder. Such
obligation of the Trustee will be deemed to have been satisfied to the extent
that substantially comparable information is provided by the Trustee pursuant to
any requirements of the Code as are from time to time in effect.

         Notices. Unless otherwise provided in the applicable Prospectus
Supplement,any notice required to be given to a holder of a Registered Debt Unit
will be mailed to the last address of such holder set forth in the applicable
Debt Unit Register.

Evidence as to Compliance

         Unless otherwise specified in the applicable Prospectus Supplement, the
Trust Agreement will provide that commencing on a certain date and on or before
a specified date in each year thereafter, a firm of independent public
accountants will furnish a statement to the Trustee to the effect that such firm
has examined certain documents and records relating to the administration of the
Deposited Assets during the related 12-month period (or, in the case of the
first such report, the period ending on or before the date specified in the
Prospectus Supplement, which date shall not be more than one year after the
related Original Issue Date) and that, on the basis of certain agreed upon
procedures considered appropriate under the circumstances, such firm is of the
opinion that such administration was conducted in compliance with the terms of
the Trust Agreement, except for such exceptions as such firm shall believe to be
immaterial and such other exceptions and qualifications as shall be set forth in
such report.

         The Trust Agreement will also provide for delivery to the Depositor,
the Administrative Agent, if any, and the Trustee on behalf of the Debt
Unitholders, on or before a specified date in each year, of an annual statement
signed by two officers of the Trustee to the effect that the Trustee has
fulfilled its obligations under the Trust Agreement throughout the preceding
year with respect to any Series of Debt Units.

         Copies of the annual accountants' statement, if any, and the statement
of officers of the Trustee may be obtained by Debt Unitholders without charge
upon written request to either the Administrative Agent or the Trustee, as
applicable, at the address set forth in the applicable Prospectus Supplement.

Replacement Debt Units

         If a mutilated Debt Unit is surrendered at the corporate trust office
or agency of the Trustee in the City and State of New York or the Depositor and
the Trustee receive satisfactory evidence that such Debt Unit has been lost,
destroyed or stolen it may be replaced upon payment by the holder of such
expenses as may be incurred by the Trustee in connection therewith and the
furnishing of such security and indemnity as the Trustee and the Depositor may
require to hold each of them and any Paying Agent harmless; provided that
neither the Depositor nor the Trustee has received notice that such Debt Unit
was acquired by a bona fide purchaser.

Termination

         The obligations created by the Trust Agreement for each Series of Debt
Units will terminate upon the payment to Debt Unitholders of that Series of all
amounts held in the related Debt Unit Account and required to be paid to them
pursuant to the Trust Agreement following final payment or other liquidation of
any remaining Deposited Assets or Credit Support subject thereto or the
disposition of all property acquired upon foreclosure or liquidation of any such
Deposited Assets or Credit Support. In no event, however, will any Trust created
by the Trust Agreement continue beyond the respective date specified in the
applicable Prospectus Supplement, nor will

                                       36

<PAGE>



such Trust continue to exist if its existence would result in a violation of the
common-law Rule Against Perpetuities. Written notice of termination of the
obligations with respect to the related Series of Debt Units under the Trust
Agreement will be provided as set forth above under "--Reports to Debt
Unitholders; Notices", and the final distribution will be made only upon
surrender and cancellation of the Debt Units at an office or agency appointed by
the Trustee which will be specified in the notice of termination.

         Any such purchase of Deposited Assets or Credit Support and property
acquired in respect of Deposited Assets or Credit Support evidenced by a Series
of Debt Units shall be made at a price approximately equal to the aggregate fair
market value of all the assets in the Trust (as determined by the Trustee, the
Administrative Agent, if any, and, if different than both such persons, the
person entitled to effect such termination), in each case taking into account
accrued interest at the applicable interest rate to the first day of the month
following such purchase or, to the extent specified in the applicable Prospectus
Supplement, a specified price as determined therein (such price, a "Purchase
Price"). The exercise of such right will effect early retirement of the Debt
Units of that Series, but the right of the person entitled to effect such
termination is subject to the aggregate principal balance of the outstanding
Deposited Assets or Credit Support for such Series at the time of purchase being
less than the percentage of the aggregate principal balance of the Deposited
Assets or the Credit Support at the Cut-off Date (as defined in the Trust
Agreement) for the Series specified in the applicable Prospectus Supplement.

Duties of the Trustee

         The Trustee makes no representations as to the validity or sufficiency
of the Trust Agreement, the Debt Units of any Series or any Deposited Asset or
related document and is not accountable for the use or application by or on
behalf of any Administrative Agent of any funds paid to such Administrative
Agent or its designee in respect of such Debt Units or the Deposited Assets, or
deposited into or withdrawn from the related Debt Unit Account or any other
account by or on behalf of such Administrative Agent. If no Administrative Agent
Termination Event has occurred and is continuing with respect to any given
Series, the Trustee is required to perform only those duties specifically
required under the Trust Agreement with respect to such Series. However, upon
receipt of the various certificates, reports or other instruments required to be
furnished to it, the Trustee is required to examine such documents and to
determine whether they conform to the applicable requirements of the Trust
Agreement.

The Trustee

         The Trustee for any given Series of Debt Units under the Trust
Agreement will be named in the applicable Prospectus Supplement. The commercial
bank, national banking association or trust company serving as Trustee will be
unaffiliated with, but may have banking relationships with or provide financial
services to, the Depositor, any Administrative Agent and their affiliates.


                                 CURRENCY RISKS

Exchange Rates and Exchange Controls

         An investment in a Debt Unit having a Specified Currency other than
U.S. dollars entails significant risks that are not associated with a similar
investment in a security denominated in U.S. dollars. Such risks include,
without limitation, the possibility of significant changes in rates of exchange
between the U.S. dollar and such Specified Currency and the possibility of the
imposition or modification of foreign exchange controls with respect to such
Specified Currency. Such risks generally depend on factors over which the
Depositor has no control, such as economic and political events and the supply
of and demand for the relevant currencies. In recent years, rates of exchange
between the U.S. dollar and certain currencies have been highly volatile, and
such volatility may be expected in the future. Fluctuations in any particular
exchange rate that have occurred in the past are not necessarily indicative,
however, of fluctuations in the rate that may occur during the term of any Debt
Unit. Depreciation of the Specified Currency for a Debt Unit against the U.S.
dollar would result in a decrease in the effective yield of such Debt Unit below
its Debt Unit Rate and, in certain circumstances, could result in a loss to the
investor on a U.S. dollar basis.

                                       37

<PAGE>




         Governments have from time to time imposed, and may in the future
impose, exchange controls that could affect exchange rates as well as the
availability of a Specified Currency for making distributions in respect of Debt
Units denominated in such currency. At present, the Depositor has identified the
following currencies in which distributions of principal, premium and interest
on Debt Units may be made: Australian dollars, Canadian dollars, Danish kroner,
Italian lire, Japanese yen, New Zealand dollars, U.S. dollars and ECU. However,
Debt Units distributable with Specified Currencies other than those listed may
be issued at any time. There can be no assurance that exchange controls will not
restrict or prohibit distributions of principal, premium or interest in any
Specified Currency. Even if there are no actual exchange controls, it is
possible that, on a Distribution Date with respect to any particular Debt Unit,
the currency in which amounts then due to be distributed in respect of such Debt
Unit are distributable would not be available. In that event, such payments will
be made in the manner set forth above under "Description of Debt Units--General"
or as otherwise specified in the applicable Prospectus Supplement.

         PROSPECTIVE PURCHASERS SHOULD CONSULT THEIR OWN FINANCIAL AND LEGAL
ADVISORS AS TO THE RISKS ENTAILED BY AN INVESTMENT IN DEBT UNITS DENOMINATED IN
A CURRENCY OTHER THAN U.S. DOLLARS. SUCH DEBT UNITS ARE NOT AN APPROPRIATE
INVESTMENT FOR PERSONS WHO ARE UNSOPHISTICATED WITH RESPECT TO FOREIGN CURRENCY
TRANSACTIONS.

         The information set forth in this Prospectus is directed to prospective
purchasers of Debt Units who are United States residents. The applicable
Prospectus Supplement for certain issuances of Debt Units may set forth certain
information applicable to prospective purchasers who are residents of countries
other than the United States with respect to matters that may affect the
purchase or holding of, or receipt of distributions of principal, premium or
interest in respect of, such Debt Units.

         Any Prospectus Supplement relating to Debt Units having a Specified
Currency other than U.S. dollars will contain information concerning historical
exchange rates for such currency against the U.S. dollar, a description of such
currency, any exchange controls affecting such currency and any other required
information concerning such currency.


                     CERTAIN FEDERAL INCOME TAX CONSEQUENCES

         Certain of the Federal income tax consequences of the purchase,
ownership and disposition of Debt Units that will apply to any Series of Debt
Units will be set forth in the applicable Prospectus Supplement.


                              ERISA CONSIDERATIONS

         The Employee Retirement Income Security Act of 1974, as amended
("ERISA"), and the Code impose certain requirements on (a) an employee benefit
plan (as defined in Section 3(3) of ERISA), (b) a plan described in Section
4975(e)(i) of the Code or (c) any entity whose underlying assets include plan
assets by reason of a plan's investment in the entity (each, a "Plan").

         In accordance with ERISA's general fiduciary standards, before
investing in a Debt Unit, a Plan fiduciary should determine whether such an
investment is permitted under the governing Plan instruments and appropriate for
the Plan in view of the Plan's overall investment policy and the composition and
diversification of its portfolio. Other provisions of ERISA and the Code
prohibit certain transactions involving the assets of a Plan and persons who
have certain specified relationships to the Plan ("parties in interest" within
the meaning of ERISA or "disqualified persons" within the meaning of the Code).
Thus, a Plan fiduciary considering an investment in Debt Units should also
consider whether such an investment might constitute or give rise to a
prohibited transaction under ERISA or the Code.

         An investment in Debt Units by a Plan might result in the assets of the
Trust being deemed to constitute Plan assets, which in turn might mean that
certain aspects of such investment, including the operation of the trust, might
be prohibited transactions under ERISA and the Code. Neither ERISA nor the Code
defines the term "plan

                                       38

<PAGE>



assets". Under Section 2510.3-101 of the United States Department of Labor
regulations (the "Regulation"), a Plan's assets may include an interest in the
underlying assets of an entity (such as a trust) for certain purposes, including
the prohibited transaction provisions of ERISA and the Code, if the Plan
acquires an "equity interest" in such entity. Thus, if a Plan acquired a Debt
Unit, for certain purposes under ERISA and the Code (including the prohibited
transaction provisions) the Plan would be considered to own its share of the
underlying assets of the Trust unless (1) such Debt Unit is a "publicly-offered
security" or (2) equity participation by "benefit plan investors" is not
"significant".

         Under the Regulations, a publicly offered security is a security that
is (1) freely transferable, (2) part of a class of securities that is owned by
100 or more investors independent of the issuer and of one another at the
conclusion of the initial offering and (3) either is (A) part of a class of
securities registered under Section 12(b) or 12(g) of the Exchange Act or (B)
sold to the Plan as part of an offering of securities to the public pursuant to
an effective registration statement under the Securities Act and the class of
securities of which such security is a part is registered under the Exchange Act
within 120 days (or such later time as may be allowed by the Commission) after
the end of the fiscal year of the issuer during which the offering of such
securities to the public occurred.

         Participation by benefit plan investors in the Debt Units would not be
significant if immediately after the most recent acquisition of a Debt Unit,
whether or not from the Depositor or Merrill Lynch & Co., less than 25% of (1)
the value of such class of Debt Units and (2) the value of any other class of
Debt Units that is not a publicly-offered security under the Regulation, were
held by benefit plan investors, which are defined as Plans and employee benefit
plans not subject to ERISA (for example, governmental plans).

         It is anticipated that certain offerings of Debt Units will be
structured so that assets of the Trust will not be deemed to constitute Plan
assets. In such cases, the relevant Prospectus Supplement will indicate either
that the Debt Units will be considered publicly offered securities under the
Regulation or that participation by benefit plan investors will not be
significant for purposes of the Regulation.

         In other instances, however, the offering of Debt Units may not be so
structured. Thus, the assets of the Trust may be deemed to be Plan assets and
transactions involving the Depositor, an underwriter, the Trustee, any trustee
with respect to Underlying Securities, any obligors with respect to Underlying
Securities or affiliates of such obligors might constitute prohibited
transactions with respect to a Plan holding a Debt Unit unless (i) one or more
prohibited transaction exemptions ("PTEs") applies or (ii) in the case of an
issuer of Underlying Securities, it is not a disqualified person or party in
interest with respect to such Plan. Plans maintained or contributed to by the
Depositor, an underwriter, the Trustee, a trustee with respect to Underlying
Securities, any issuer of underlying securities, or any of their affiliates,
should not acquire or hold any Debt Unit.

               If the Trust is deemed to hold Plan assets, the Underlying
Securities would appear to be an indirect loan between the issuer of the
Underlying Securities and any Plan owning Debt Units; however, such loan, by
itself, would not constitute prohibited transaction unless such issuer is a
party in interest or disqualified person with respect to such Plan.

               If the underwriter with respect to an offering of Debt Units is a
broker-dealer registered under the Exchange Act, and customarily purchases and
sells securities for its own account in the ordinary course of its business as a
broker-dealer, sales of Debt Units by such underwriter to Plans may be exempt
under PTE 75-1 if the following conditions are satisfied: (i) the underwriter is
not a fiduciary with respect to the Plan and is party in interest or
disqualified person solely by reason of Section 3(14)(B) of ERISA or Section
4975(e)(2)(B) of the Code or a relationship to a person described in such
Sections, (ii) the transaction is at least as favorable to the Plan as an
arms-length transaction with an unrelated party and is not a prohibited
transaction within the meaning of Section 503(b) of the Code, and (iii) the Plan
maintains for at least six years such records as are necessary to determine
whether the conditions)s of PTE 75-1 have been met.

               The custodial and other services tendered by the Trustee and any
trustee with respect to Underlying Securities might be exempt pursuant to
Section 408(b)(2) of ERISA and Section 4975(d)(2) of the Code, which exempt
services necessary for the establishment or operation of a Plan under a
reasonable contract or arrangement and for which no more than reasonable
compensation is paid. An arrangement would not be treated as reasonable

                                       39

<PAGE>



unless it can be terminated upon reasonably short notice under the circumstances
without penalty. The statutory exemption for services noted above does not
provide exemptive relief from prohibited transactions described in Section
406(b) of ERISA or Section 4975(c)(1)(E) or (F) of the Code.

               Other prohibited transaction exemptions could apply to the
acquisition and holding of Debt Units by Plans, and the operation of the Trust,
including, but not limited to: PTE 84-14 (an exemption for certain transaction
determined by An independent qualified professional asset manager), PTE 91-38
(an exemption for certain transactions involving bank collective investment
funds), PTE 90-1 (an exemption for certain transactions involving insurance
company pooled separate accounts) or PTE 95-60 (an exemption for certain
transactions involving insurance company pooled general accounts).

               The Prospectus Supplement relating to any offering of Debt Units
that will result in the Trust Assets being deemed to constitute Plan assets will
provide that, by acquiring and holding a Debt Unit, a Plan shall be deemed to
have represented and warranted to the Depositor, Trustee, and underwriter that
such acquisition and holding of a Debt Unit does not involve a non-exempt
prohibited transaction with respect to such Plan, including with respect to the
activities of the Trust.


         ANY PLAN OR INSURANCE COMPANY INVESTING ASSETS OF ITS GENERAL ACCOUNT
PROPOSING TO ACQUIRE DEBT UNITS SHOULD CONSULT WITH ITS COUNSEL.

                              PLAN OF DISTRIBUTION

         Debt Units may be offered in any of three ways: (i) through
underwriters or dealers; (ii) directly to one or more purchasers; or (iii)
through agents. The applicable Prospectus Supplement will set forth the material
terms of the offering of any Series of Debt Units, which may include the names
of any underwriters, or initial purchasers, the purchase price of such Debt
Units and the proceeds to the Depositor from such sale, any underwriting
discounts and other items constituting underwriters' compensation, any initial
public offering price, any discounts or concessions allowed or reallowed or paid
to dealers, any securities exchanges on which such Debt Units may be listed, and
the place and time of delivery of the Debt Units to be offered thereby.

         If underwriters are used in the sale, Debt Units will be acquired by
the underwriters at a fixed price for their own account and may be resold from
time to time in one or more transactions, including negotiated transactions, at
a fixed public offering price or at varying prices determined at the time of
sale. Such Debt Units may be offered to the public either through underwriting
syndicates represented by managing underwriters or by underwriters without a
syndicate. Such managing underwriters or underwriters in the United States will
include Merrill Lynch & Co. Unless otherwise set forth in the applicable
Prospectus Supplement, the obligations of the underwriters to purchase such Debt
Units will be subject to certain conditions precedent, and the underwriters will
be obligated to purchase all such Debt Units if any of such Debt Units are
purchased. Any initial public offering price and any discounts or concessions
allowed or reallowed or paid to dealers may be changed from time to time.

         Debt Units may also be sold through agents designated by the Depositor
from time to time. Any agent involved in the offer or sale of Debt Units will be
named, and any commissions payable by the Depositor to such agent will be set
forth, in the applicable Prospectus Supplement. Unless otherwise indicated in
the applicable Prospectus Supplement, any such agent will act on a best-efforts
basis for the period of its appointment.

         If so indicated in the applicable Prospectus Supplement, the Depositor
will authorize agents, underwriters or dealers to solicit offers by certain
specified institutions to purchase Debt Units at the public offering price
described in such Prospectus Supplement pursuant to delayed delivery contracts
providing for payment and delivery on a future date specified in such Prospectus
Supplement. Such contracts will be subject only to those conditions set forth in
the applicable Prospectus Supplement and such Prospectus Supplement will set
forth the commissions payable for solicitation of such contracts. Any
underwriters, dealers or agents participating in the distribution of Debt Units
may be deemed to be underwriters and any discounts or commissions received by
them on the sale or resale of Debt Units may be deemed to be underwriting
discounts and commissions under the Securities Act. Agents and underwriters may
be entitled under agreements entered into with the Depositor to indemnification
by the Depositor

                                       40

<PAGE>



against certain civil liabilities, including liabilities under the Securities
Act, or to contribution with respect to payments that the agents or underwriters
or their affiliates may be required to make in respect thereof. Agents and
underwriters and their affiliates may be customers of, engage in transactions
with, or perform services for, the Depositor or its affiliates in the ordinary
course of business.

         Only Debt Units rated in one of the investment grade rating categories
by a Rating Agency will be offered hereby. Affiliates of the underwriters may
act as agents or underwriters in connection with the sale of the Debt Units. Any
affiliate of the underwriters so acting will be named, and its affiliation with
the underwriters described, in the applicable Prospectus Supplement. The
underwriters or their affiliates may act as principals or agents in connection
with market-making transactions relating to the Debt Units. A Prospectus
Supplement will be prepared with respect to the Debt Units for use by such
underwriters or affiliates in connection with offers and sales related to
market-making transactions in the Debt Units.

         The Depositor is an affiliate of Merrill Lynch & Co.


                                  LEGAL MATTERS

         The validity of the Debt Units will be passed upon for the Depositor
and the underwriters by Shearman & Sterling, New York, New York or other counsel
identified in the applicable Prospectus Supplement.

ITEM 15.     INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Section 145 of the Delaware General Corporation Law provides, in
summary, that directors and officers of Delaware corporations are entitled,
under certain circumstances, to be indemnified against all expenses and
liabilities (including attorney's fees) incurred by them as a result of suits
brought against them in their capacity as directors or officers, if they acted
in good faith and in a manner they reasonably believed to be in or not opposed
to the best interests of the company, and, with respect to any criminal action
or proceeding, if they had no reasonable cause to believe their conduct was
unlawful; provided that no indemnification may be made against expenses in
respect of any claim, issue or matter as to which they shall have been adjudged
to be liable to the company, unless and only to the extent that the court in
which such action or suit was brought shall determine upon application that,
despite the adjudication of liability but in view of all the circumstances of
the case, they are fairly and reasonably entitled to indemnity for such expenses
which the court shall deem proper. Any such indemnification may be made by the
company only as authorized in each specific case upon a determination by the
stockholders of disinterested directors that indemnification is proper because
the indemnitee has met the applicable standard of conduct.

         The Registrant's Amended and Restated Certificate of Incorporation
provides that no director of the Registrant shall be personally liable to the
Registrant or its stockholders for monetary damages for breach of fiduciary duty
as a director, except for liability: (i) for any breach of the director's duty
of loyalty to the Registrant or its stockholders; (ii) for acts or omissions not
in good faith or which involve intentional misconduct or a knowing violation of
law; (iii) in respect of certain unlawful dividend payments or stock redemptions
or purchases; or (iv) for any transaction from which the director derived an
improper personal benefit.

         The Registrant's Amended and Restated Certificate of Incorporation and
By-Laws provide for indemnification of its directors and officers to the fullest
extent permitted by Delaware law, as the same may be amended from time to time.

         Reference is made to Section 6 of the form of Underwriting Agreement
filed as Exhibit 1.1 hereto for provisions relating to the indemnification of
directors, officers and controlling persons against certain liabilities
including liabilities under the Securities Act of 1933, as amended.

         (1) To file, during any period in which offers or sales are being made,
a post-effective amendment to this Registration Statement:

                  (i) To include any prospectus required by Section 10(a)(3) of
         the Securities Act of 1933;

                  (ii) To reflect in the prospectus any facts or events arising
         after the effective date of the Registration Statement (or the most
         recent post-effective amendment thereof) which, individually or in the
         aggregate, represent a fundamental change in the information set forth
         in the Registration Statement; and

                  (iii) To include any material information with respect to the
         plan of distribution not previously disclosed in the Registration
         Statement or any material change to such information in the
         Registration Statement.

         (2) That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

         (3) To remove from registration by means of a post-effective amendment
any of the securities being registered which remain unsold at the termination of
the offering.

         The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 that is incorporated by reference in the Registration
Statement shall be deemed to be a new registration statement relating to the
securities offered therein and the offering of such securities at that time
shall be deemed to be the initial bona fide offering thereof.

         The undersigned Registrant hereby undertakes that:

         (1) For purposes of determining any liability under the Securities Act
of 1933, the information omitted from the form of prospectus filed as part of
this Registration Statement in reliance upon Rule 430A and contained in a form
of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4), or
497(h) under the Securities Act of 1933 shall be deemed to be a part of this
Registration Statement as of the time it was declared effective.

         (2) For the purpose of determining any liability under the Securities
Act of 1933, each post-effective amendment that contains a form of prospectus
shall be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.

         Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the Registrant, pursuant to the foregoing provisions, or otherwise, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission, such indemnification is against public policy as expressed in the
Securities Act of 1933 and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the Registrant of expenses incurred or paid by a director, officer or
controlling person of the Registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the Registrant, will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act of 1933 and will be governed by the final adjudication of such
issue.
